RESUMEN

BACKGROUND: One of the greatest challenges in using Lactobacillus acidophilus as a probiotic is acid stress. The current research aimed to identify substances that help L. acidophilus resist acid stress; this was achieved through assessing its nutrient consumption patterns under various pH conditions. RESULTS: The consumption rates of alanine, uracil, adenine, guanine, niacin, and manganese were consistently higher than 60% for L. acidophilus LA-5 cultured at pH 5.8, 4.9, and 4.4. The consumption rates of glutamic acid + glutamine and thiamine increased with decreasing pH and were higher than 60% at pH 4.9 and 4.4. The viable counts of L. acidophilus LA-5 were significantly increased under the corresponding acidic stress conditions (pH 4.9 and 4.4) through the appropriate addition of either alanine (3.37 and 2.81 mmol L-1), glutamic acid + glutamine (4.77 mmol L-1), guanine (0.13 and 0.17 mmol L-1), niacin (0.02 mmol L-1), thiamine (0.009 mmol L-1), or manganese (0.73 and 0.64 mmol L-1) (P < 0.05). The viable counts of L. acidophilus LA-5 cultured in a medium supplemented with combined nutritional factors was 1.02-1.03-fold of the counts observed in control medium under all acid conditions (P < 0.05). CONCLUSION: Alanine, glutamic acid + glutamine, guanine, niacin, thiamine, and manganese can improve the growth of L. acidophilus LA-5 in an acidic environment in the present study. The results will contribute to optimizing strategies to enhance the acid resistance of L. acidophilus and expand its application in the fermentation industry. © 2024 Society of Chemical Industry.

RESUMEN

BACKGROUND: Standard treatment for drug-susceptible tuberculosis (DS-TB) includes a multidrug regimen requiring at least 6 months of treatment, and this lengthy treatment easily leads to poor adherence. There is an urgent need to simplify and shorten treatment regimens to reduce interruption and adverse event rates, improve compliance, and reduce costs. METHODS: ORIENT is a multicenter, randomized controlled, open-label, phase II/III, non-inferiority trial involving DS-TB patients to evaluate the safety and efficacy of short-term regimens compared with the standardized six-month treatment regimen. In stage 1, corresponding to a phase II trial, a total of 400 patients are randomly divided into four arms, stratified by site and the presence of lung cavitation. Investigational arms include 3 short-term regimens with rifapentine 10 mg/kg, 15 mg/kg, and 20 mg/kg, while the control arm uses the standardized six-month treatment regimen. A combination of rifapentine, isoniazid, pyrazinamide, and moxifloxacin is administered for 17 or 26 weeks in rifapentine arms, while a 26-week regimen containing rifampicin, isoniazid, pyrazinamide, and ethambutol is applied in the control arm. After the safety and preliminary effectiveness analysis of patients in stage 1, the control arm and the investigational arm meeting the conditions will enter into stage 2, which is equivalent to a phase III trial and will be expanded to recruit DS-TB patients. If all investigational arms do not meet the safety conditions, stage 2 will be canceled. In stage 1, the primary safety endpoint is permanent regimen discontinuation at 8 weeks after the first dose. The primary efficacy endpoint is the proportion of favorable outcomes at 78 weeks after the first dose for both two stages. DISCUSSION: This trial will contribute to the optimal dose of rifapentine in the Chinese population and suggest the feasibility of the short-course treatment regimen containing high-dose rifapentine and moxifloxacin for DS-TB. TRIAL REGISTRATION: The trial has been registered on ClinicalTrials.gov on 28 May 2022 with the identifier NCT05401071.

RESUMEN

Objectives: To assess the contemporary prevalence and decadal trends of depression and antidepressant use among adults with cardiovascular disease (CVD) in the United States, as well as their risk factors from 2009 to 2020. Materials and methods: We used the National Health and Nutrition Examination Survey data to calculate the weighted prevalence of depression and antidepressant use. Adults aged 20 years or older with CVD were included. Depression and CVD were assessed by the Patient Health Questionnaire (PHQ-9) and self-report, respectively. Results: A total of 3,073 eligible participants with CVD aged >20 years were included. The overall prevalence of depression defined by PHQ-9 score ≥10 was 15.7% (95% CI 13.8-17.5), with a steady trend during 2009-March 2020 (p = 0.777). Female gender (aOR 1.78, 95% CI 1.20-2.64) and sleep disorder (aOR 2.62, 95% CI 1.78-3.86) were independent risk factors for depression in CVD patients, while high education level, high income, longer sleep duration, and non-current smokers were considered protective factors. The weighted prevalence of antidepressant use among depressed patients with CVD was 38.6%, which also remained unchanged during the survey period (p = 0.699). Participants with normal sleep pattern and duration were significantly less likely to take antidepressants (p = 0.003). Conclusion: The longitudinal trends in the prevalence of depression among CVD patients in the United States have been stable over the past decade, despite being significantly higher in women, and those with sleep disorders. Overall, antidepressant use was fairly low. Aggressive screening and tailored treatment are recommended for specific vulnerable subpopulations to improve their clinical outcomes.

RESUMEN

The present study explored the regularity of prescriptions for the treatment of intermediate and advanced lung cancer to provide references for clinical medication. CNKI, Wanfang, VIP, and CBM were searched for the research papers on the treatment of lung cancer by Chinese medicine published from database inception to May 31, 2021. The relevant information of qualified papers was extracted to establish a database. The Chinese medicines with frequency >3% underwent analysis of the latent structure and association rules by Lantern 5.0 and SPSS Molder 14.1, respectively, and the prescription regularity in the treatment of intermediate and advanced lung cancer was analyzed based on the frequency description. A total of 713 papers were included, involving 327 Chinese medicines with a cumulative frequency of 12 794 and 106 prescriptions with a cumulative frequency of 824. The commonly used Chinese medicines were dominated by deficiency-tonifying, heat-clearing, phlegm-resolving, and cough/dyspnea-relieving drugs, such as Astragali Radix, Atractylodis Macrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Ophiopogonis Radix, Poria, and Hedyotis Diffusa, which are cold, warm, and plain in nature and sweet, bitter, and pungent in flavor, and mainly act on lung, spleen, and stomach meridians. Commonly used prescriptions included Shashen Maidong Decoction, Liujunzi Decoction, and Baihe Gujin Decoction. The latent structure analysis revealed 32 latent variables and 65 hidden classes. Six comprehensive clustering models and 11 core prescriptions were obtained by professional knowledge inference. The common syndromes of intermediate and advanced lung cancer were inferred to be Qi and Yin deficiency in the lung, Qi deficiency in the lung and spleen, Yin deficiency in the liver and kidney, combined phlegm and stasis, phlegm-heat obstructing lung, and Qi stagnation and blood stasis. Forty-four strong associations were screened out by association rules analysis, including four pairwise strong associations(Polygonati Odorati Rhizoma→Ophiopogonis Radix, Polygonati Odorati Rhizoma→Glehniae Radix, Amomi Fructus→Atractylodis Macrocephalae Rhizoma, and Polygonati Rhizoma→Astragali Radix) and 40 triplet strong associations(such as Trichosanthis Radix+Glehniae Radix→Ophiopogonis Radix, Polygonati Odorati Rhizoma+Glehniae Radix→Ophiopogonis Radix, Trichosanthis Radix+Ophiopogonis Radix→Glehniae Radix, and Scutellariae Barbatae Herba+Codonopsis Radix→Hedyotis Diffusa). In the treatment of intermediate and advanced lung cancer, Qi-replenishing and Yin-nourishing drugs are mainly employed, assisted with cancer-resisting, toxin-removing, spleen-invigorating, phlegm/stasis-resolving, and blood-activating drugs based on syndrome differentiation. The roots were treated following the principles of tonifying lungs and replenishing the spleen, and symptoms following the principles of removing the toxin, dispelling stasis, and resolving phlegm.

RESUMEN

PURPOSE: It is important to predict the prognosis of patients with prolonged disorders of consciousness (DOC). This study established and validated a nomogram and corresponding web-based calculator to predict outcomes for patients with prolonged DOC. METHODS: All data were obtained from the First Affiliated Hospital of Nanchang University and the Shangrao Hospital of Traditional Chinese Medicine. Predictive variables were identified by univariate and multiple logistic regression analyses. Receiver operating characteristic curves, calibration curves, and a decision curve analysis (DCA) were utilized to assess the predictive accuracy, discriminative ability, and clinical utility of the model, respectively. RESULTS: Independent prognostic factors, such as age, Glasgow coma scale score, state of consciousness, and brainstem auditory-evoked potential grade were integrated into a nomogram. The model demonstrated good discrimination in the training and validation cohorts, with area-under-the-curve values of 0.815 (95% confidence interval [CI]: 0.748-0.882) and 0.805 (95% CI: 0.727-0.883), respectively. The calibration plots and DCA demonstrated good model performance and clear clinical benefits in both cohorts. CONCLUSIONS: Based on our nomogram, we developed an effective, simple, and accurate model of a web-based calculator that may help individualize healthcare decision-making. Further research is warranted to optimize the system and update the predictors.

RESUMEN

OBJECTIVE: To explore the efficacy and safety of Zhuang medicine medicated thread moxibustion (ZMTM) on psoriasis vulgaris. METHODS: A multicenter, randomized, parallel controlled clinical trial was designed. A total of 241 outpatients with psoriasis vulgaris were randomly divided into a control group (120 cases) and a treatment group (121 cases) using a central block randomization from June 2015 to May 2018. The control group was treated with Western medicines alone including pidotimod dispersible tablets, vitamin B compound tablets, and compound cod liver oil-zinc oxide ointment. The treatment group was treated with ZMTM every 2 days combined with Western medicines. The two groups received continuous intervention for 30 days. The primary outcome was Psoriasis Area and Severity Index (PASI), and the secondary outcomes included Itch Rating Scale, Dermatology Quality of Life Index (DLQI), Hamilton Anxiety Rating Scale (HAMA), as well as PASI response rate. Meanwhile, adverse events were evaluated during the whole clinical trial. Follow-up was carried out 30 days after treatment. RESULTS: There were 5 cases of shedding in this trial. In intention-to-treat analysis, 236 cases were included and each group contained 118 cases. On the 30th and 60th days, PASI scores of patients in each group were significantly lower than that at baseline (P<0.01) and the PASI score reduction of the treatment group was greater than that of the control group (P<0.01). Itch Rating Scale, DLQI, and HAMA scale were decreased in both groups after treatment, and the treatment group showed a better therapeutic effect (P<0.01). The response rates of PASI 50 and 75 were significantly higher than those in the control group [81.4% (96/118), 43.2% (51/118) vs. 41.5% (49/118), 11.0% (13/118), respectively, P<0.05]. During follow-up, the improvements in scores of PASI, Itch Rating Scale, DLQI, and HAMA of the treatment group were significantly greater than those of the control group (P<0.01). The response rates of PASI 50 and 75 in the treatment group were significantly higher than those in the control group, respectively (both P<0.05). No obvious adverse reaction was found in either group. CONCLUSION: ZMTM combined with Western medicines showed a better therapeutic effect in the treatment of psoriasis vulgaris without obvious adverse reaction. (Trial Registration No. ChiCTR-IOR-16008159).

RESUMEN

OBJECTIVE: To explore the characteristics and rule of clinical acupoint selection in treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). METHODS: The clinical articles of acupuncture in treatment of AECOPD were retrieved from the databases of PubMed, EMbase, Cochrane Library, Web of Science, CNKI, Wanfang, VIP and SinoMed, from the date of establishment to July 15, 2020. The articles were screened in accordance with the inclusion and exclusion criteria, the prescriptions of acupuncture and the relevant information of the acupoints and meridians were extracted to establish the database. The data mining methods i.e. Apriori association rule analysis and cluster analysis were used to analyse the using frequency, involving meridians, acupoint distributions, association rules and cluster of selected acupoints. RESULTS: A total of 54 articles were included, 67 acupuncture prescriptions were extracted, 69 acupoints were involved and the total using frequency was 475 times. The top 5 acupoints in frequency were Danzhong (CV 17), Feishu (BL 13), Zusanli (ST 36), Fenglong (ST 40) and Dingchuan (EX-B1). The main involved meridians were bladder meridian of foot-taiyang, conception vessel, stomach meridian of foot-yangming and lung meridian of hand-taiyin. The acupoints were mainly distributed in chest and abdomen, waist and dorsum. The mainly selected special points were five-shu points, front-mu points, convergent points and back-shu points. Twenty strong association rules were summarized by association rule analysis, including Fenglong (ST 40)Þ Zusanli (ST 36), Fengmen (BL 12)Þ Danzhong (CV 17), Tianshu (ST 25)Þ Zhongwan (CV 12), Dingchuan (EX-B1)+ Feishu (BL 13) Þ Danzhong (CV 17), Fenglong (ST 40)+ Feishu (BL 13) Þ Zusanli (ST 36), etc. Five cluster groups were summarized by cluster analysis, i.e. ①Feishu (BL 13), ② Dingchuan (EX-B1) and Danzhong (CV 17), ③ Chize (LU 5), Lieque (LU 7) and Fengmen (BL 12), ④Zusanli (ST 36) and Fenglong (ST 40), ⑤Tianshu (ST 25), Guanyuan (CV 4) and Zhongwan (CV 12). CONCLUSION: The local acupoints and acupoints along meridians are the main acupuncture prescriptions for AECOPD, and the special points are the predominated selection. The acupoint compatibility embodies the therapeutic principle of "strengthening vital qi to eliminate pathogenic factors and considering both the root cause and symptoms".

RESUMEN

BACKGROUND: Among discharged COVID-19 patients, the health-related quality of life is poor, and patients suffer from significant physical and psychological impairment. This study was designed to investigate the effects of Liuzijue exercise on the rehabilitation of COVID-19 patients. METHODS: Thirty three eligible patients with COVID-19 were enrolled in the study after discharge. All the participants practiced Liuzijue exercise once per day for 20 minutes over 4 weeks. Data were collected at baseline and the end of the intervention. Primary outcomes involved functional capacity and secondary outcomes involved quality of life. RESULTS: The maximal inspiratory pressure (MIP), peak inspiratory flow (PIF), and diaphragm movement in deep breathing (DM-DB) of patients increased significantly after 4 weeks of intervention. The dyspnea was also alleviated and exercise capacity was significantly improved. In terms of quality of life, physical functioning and role-physical scores were significantly increased. Moreover, Liuzijue could significantly alleviate the depression and anxiety status of the patients. CONCLUSION: Liuzijue exercise is a viable alternative home exercise program that produced better functional capacity and quality of life in discharged patients with COVID-19. These findings also showed the necessity of rehabilitation intervention for cured COVID-19 patients.

RESUMEN

The exacerbation of oxidative and inflammatory reactions has been involved in atherosclerotic cardiovascular diseases leading to morbidity and mortality worldwide. Discovering the underlying mechanisms and finding optimized curative approaches to control the global prevalence of cardiovascular diseases is needed. Growing evidence has demonstrated that gut microbiota is associated with the development of atherosclerosis, while berberine, a natural product exhibits antiatherogenic effects in clinical and pre-clinical studies, which implies a potential link between berberine and gut microbiota. In light of these novel discoveries, evidence of the role of berberine in modulating atherosclerosis with a specific focus on its interaction with gut microbiota is collected. This review synthesizes and summarizes antioxidant and anti-inflammatory effects of berberine on combating atherosclerosis experimentally and clinically, explores the interaction between berberine and intestinal microbiota comprehensively, and provides novel insights of berberine in managing atherosclerotic cardiovascular diseases via targeting the gut-heart axis mechanistically. The phenomenon of how berberine overcomes its weakness of poor bioavailability to conduct its antiatherogenic properties is also discussed and interpreted in this article. An in-depth understanding of this emerging area may contribute to identifying therapeutic potentials of medicinal plant and natural product derived pharmaceuticals for the prevention and treatment of atherosclerotic cardiovascular diseases in the future.

RESUMEN

Lactobacillus acidophilus LA-5 is a suitable probiotic for food application, but because of its slow growth in milk, an increase in its efficiency is desired. To shorten the time required for fermentation, the nutrient requirements of L. acidophilus LA-5 were analyzed, including the patterns of consumption of amino acids, purines, pyrimidines, vitamins, and metal ions. The nutrients required by L. acidophilus LA-5 were Asn, Asp, Cys, Leu, Met, riboflavin, guanine, uracil, and Mn2+, and when they were added to milk, the fermentation time of fermented milk prepared by L. acidophilus LA-5 alone was shortened by 9 h, with high viable cell counts that were maintained during storage of nutrient-supplemented fermented milk compared with the control. For fermented milk prepared by fermentation with Streptococcus thermophilus, Lactobacillus delbrueckii ssp. bulgaricus, and L. acidophilus LA-5, viable cell counts of L. acidophilus LA-5 increased 1.3-fold and were maintained during storage of nutrient-supplemented fermented milk compared with the control. Adding nutrients had no negative effect on the quality of the fermented milk. The results indicated that suitable nutrients enhanced the growth of L. acidophilus LA-5 and increased its viable cell counts in fermented milk prepared by L. acidophilus LA-5 alone and mixed starter culture, respectively.

RESUMEN

INTRODUCTION: To explore the underlying mechanism of electroacupuncture (EA) treatment on central post-stroke pain (CPSP), and provide basic evidence for the EA treatment on CPSP. METHODS: Firstly, 40 male SD rats were successfully established with a model of CPSP, under the intervention of different EA frequencies (2 Hz and 15 Hz) and fluoxetine (5 ml/kg and 0.4 mg/ml), whose brain tissue was then removed for paraffin-embedded sectioning; secondly, LPS induced the primary brain cells in the hippocampus to cause inflammation model which were added NS398 (inhibitor of COX-2) and DKK-1 (inhibitor of ß-catenin) later. The lesion sites of brain tissue were observed by Nissl staining and Transmission Electron Microscope (TEM) and autophagy-related proteins (LC3B, p62, LAMP-1), COX-2 and ß-catenin were detected by Western Blot and immunohistochemical staining. Finally, the correlation between LC3B, COX-2, and ß-catenin was calculated by multispectral quantification. RESULTS: (1) In the EA group (15 Hz), the number of Nissl bodies increased, autophagy-related protein LC3B-Ⅱ/Ⅰ, LAMP-1, COX-2, and ß-catenin was lowly expressed, p62 was highly expressed; (2) COX-2, ß-catenin and LC3B are positively correlated with each other (COX-2 & ß-catenin: r = 0.923; COX-2 & LC3B: r = 0.818; ß-catenin & LC3B: r = 0.801); (3) Nissl bodies of primary brain cells of the hippocampus under LPS were like animal experiments; after addition of DKK-1, high expression of ß-catenin and COX-2 induced by LPS was significantly down-regulated, and LC3B-II/I was significantly down-regulated, and p62 protein only had up-regulation trend; after addition of NS398, COX-2 and LC3B-II/I was significantly down-regulated. CONCLUSION: EA may inhibit autophagy in the hippocampus by reducing ß-catenin/COX-2 protein expression and effectively alleviating CPSP. SIGNIFICANCE STATEMENT: Previous studies have found that EA can reduce the expression of NK-1R in damaged rats by inhibition of COX-2 and ß-catenin loops, which controls the activation of glial cells in the damaged area and the apoptosis of neuronal cells, and alleviated pain. In the male SD rat model, we evaluated this effect that EA inhibits autophagy in the hippocampus by reducing ß-catenin/COX-2 protein expression in the brain tissue. In addition, we assessed expression levels of autophagy-related proteins and genes on the inflammatory primary brain cells model. From the experiment, we found EA may inhibit autophagy in the hippocampus by reducing ß-catenin/COX-2 protein expression. These findings provide a foundation for the interpretation of the mechanism of EA on relieving CPSP in clinical practice.

RESUMEN

OBJECTIVE: To evaluate the effects of a 48-week course of adefovir dipivoxil (ADV) plus Chinese medicine (CM) therapy, namely Tiaogan Jianpi Hexue () and Tiaogan Jiedu Huashi () fomulae, in hepatitis B e antigen (HBeAg)-positive Chinese patients. METHODS: A total of 605 HBeAg-positive Chinese CHB patients were screened and 590 eligible participants were randomly assigned to 2 groups in 1:1 ratio including experimental group (EG, received ADV plus CM) and control group (CG, received ADV plus CM-placebo) for 48 weeks. The major study outcomes were the rates of HBeAg and HBV-DNA loss on week 12, 24, 36, 48, respectively. Secondary endpoints including liver functions (enzymes and bilirubin readings) were evaluated every 4 weeks at the beginning of week 24, 36, and 48. Routine blood, urine, and stool analyses in addition to electrocardiogram and abdominal B scan were monitored as safety evaluations. Adverse events (AEs) were documented. RESULTS: The combination therapy demonstrated superior HBeAg loss at 48 weeks, without additional AEs. The full analysis population was 560 and 280 in each group. In the EG, population achieved HBeAg loss on week 12, 24, 36, and 48 were 25 (8.90%), 34 (12.14%), 52 (18.57%), and 83 (29.64%), respectively; the equivalent numbers in the CG were 20 (7.14%), 41 (14.64%), 54 (19.29%), and 50 (17.86%), respectively. There was a statistically significant difference between these group values on week 48 (P<0.01). No additional AEs were found in EG. Subgroup analysis suggested different outcomes among treatment patterns. CONCLUSION: Combination of CM and ADV therapy demonstrated superior HBeAg clearance compared with ADV monotherapy. The finding indicates that this combination therapy may provide an improved therapeutic effect and safety profile (ChiCTR-TRC-11001263).

RESUMEN

With the improvement of people's living standard and the change of dietary structure, the prevalence of gout has increased gradually with the increased intake of protein, sugar and fat. There has been a positive correlation between gout and age, and the age of onset decreased gradually. The inflammation induced by sodium urate crystal is the pathological basis of gout, which activates innate immunity, releases many kinds of inflammatory mediators, such as interleukin(IL)-1β, IL-6 and tumor necrosis factor(TNF)-α, and then causes inflammatory cascade reaction and acute attacks, such as joint redness, swelling and heat pain. There is a spontaneous remission mechanism in gout. For one thing, macrophages reduce the stimulation of monosodium urate(MSU) through phagocytosis of MSU crystals as foreign bodies, for another, differentiated and mature macrophages secrete anti-inflammatory factor transforming growth factor(TGF)-β1, inhibit the expression of inflammatory factors and promote spontaneous relief of acute gout attack. In addition to the activation mechanism of intracellular signaling molecules associated with inflammatory response, the inflammatory mechanism of gout also involves complement activation, cell activation and other pathways. The complications caused by gout, such as cardiovascular system damage and joint destruction, are seriously harmful to human health. At present, western drugs, such as allopurinol and febuxostat, exert an effect in inhibiting xanthine oxidase. Benzimarone has effect in reducing renal absorption of uric acid and promoting uric acid excretion by inhibiting uric acid transporter 1(URAT1) and glucose transporter 9(GLUT9). Even Lesinurad and other medicines in current studies are based on the inhibition of uric acid re-absorption, but with adverse reactions that limit the clinical application. The treatment of gout with traditional Chinese medicine(TCM) has multi-target characteristics, with advantages in reducing uric acid, resisting inflammation and improving joint function and a high safety. It has been gradually popularized and applied in clinical treatment of gout. Therefore, it is a promising research direction to treat gout with TCM and western medicine based on the pathomechanism of gout.

RESUMEN

OBJECTIVE@#To evaluate the effects of a 48-week course of adefovir dipivoxil (ADV) plus Chinese medicine (CM) therapy, namely Tiaogan Jianpi Hexue () and Tiaogan Jiedu Huashi () fomulae, in hepatitis B e antigen (HBeAg)-positive Chinese patients.@*METHODS@#A total of 605 HBeAg-positive Chinese CHB patients were screened and 590 eligible participants were randomly assigned to 2 groups in 1:1 ratio including experimental group (EG, received ADV plus CM) and control group (CG, received ADV plus CM-placebo) for 48 weeks. The major study outcomes were the rates of HBeAg and HBV-DNA loss on week 12, 24, 36, 48, respectively. Secondary endpoints including liver functions (enzymes and bilirubin readings) were evaluated every 4 weeks at the beginning of week 24, 36, and 48. Routine blood, urine, and stool analyses in addition to electrocardiogram and abdominal B scan were monitored as safety evaluations. Adverse events (AEs) were documented.@*RESULTS@#The combination therapy demonstrated superior HBeAg loss at 48 weeks, without additional AEs. The full analysis population was 560 and 280 in each group. In the EG, population achieved HBeAg loss on week 12, 24, 36, and 48 were 25 (8.90%), 34 (12.14%), 52 (18.57%), and 83 (29.64%), respectively; the equivalent numbers in the CG were 20 (7.14%), 41 (14.64%), 54 (19.29%), and 50 (17.86%), respectively. There was a statistically significant difference between these group values on week 48 (P<0.01). No additional AEs were found in EG. Subgroup analysis suggested different outcomes among treatment patterns.@*CONCLUSION@#Combination of CM and ADV therapy demonstrated superior HBeAg clearance compared with ADV monotherapy. The finding indicates that this combination therapy may provide an improved therapeutic effect and safety profile (ChiCTR-TRC-11001263).

RESUMEN

OBJECTIVE: Inconsistent findings in regard to association between different concentrations of vitamin D, calcium or their combination and the risk of fracture have been reported during the past decade in community-dwelling older people. This study was designed to compare the fracture risk using different concentrations of vitamin D, calcium or their combination. DESIGN: A systematic review and network meta-analysis. DATA SOURCES: Randomised controlled trials in PubMed, Cochrane library and Embase databases were systematically searched from the inception dates to 31 December 2017. OUTCOMES: Total fracture was defined as the primary outcome. Secondary outcomes were hip fracture and vertebral fracture. Due to the consistency of the original studies, a consistency model was adopted. RESULTS: A total of 25 randomised controlled trials involving 43 510 participants fulfilled the inclusion criteria. There was no evidence that the risk of total fracture was reduced using different concentrations of vitamin D, calcium or their combination compared with placebo or no treatment. No significant associations were found between calcium, vitamin D, or combined calcium and vitamin D supplements and the incidence of hip or vertebral fractures. CONCLUSIONS: The use of supplements that included calcium, vitamin D or both was not found to be better than placebo or no treatment in terms of risk of fractures among community-dwelling older adults. It means the routine use of these supplements in community-dwelling older people should be treated more carefully. PROSPERO REGISTRATION NUMBER: CRD42017079624.

RESUMEN

The present study was designed to elucidate the beneficial effects of XJEK on myocardial infarction (MI) in rats, especially through the amelioration of endothelial dysfunction (ED). 136 Sprague-Dawley rats were randomized into 13 groups: control group for 0wk (n = 8); sham groups for 2, 4, and 6 weeks (wk); MI groups for 2, 4, and 6 wk; MI+XJEK groups for 2, 4, and 6w k; MI+Fosinopril groups for 2, 4, and 6 wk (n = 8~10). In addition, 8 rats were treated for Evans blue staining and Tetrazolium chloride (TTC) staining to determine the infarct size. Cardiac function, ECG, and cardiac morphological changes were examined. Colorimetric analysis was employed to detect nitric oxide (NO), and enzyme-linked immunosorbent assay (ELISA) was applied to determine N-terminal probrain natriuretic peptide (NT-ProBNP), endothelin-1 (ET-1), angiotensin II (Ang II), asymmetric dimethylarginine (ADMA), tetrahydrobiopterin (BH4), and endothelial NO synthase (eNOS) content. The total eNOS and eNOS dimer/(dimer+monomer) ratios in cardiac tissues were detected by Western blot. We found that administration of XJEK markedly ameliorated cardiovascular remodeling (CR), which was manifested by decreased HW/BW ratio, CSA, and less collagen deposition after MI. XJEK administration also improved cardiac function by significant inhibition of the increased hemodynamic parameters in the early stage and by suppression of the decreased hemodynamic parameters later on. XJEK also continuously suppressed the increased NT-ProBNP content in the serum of MI rats. XJEK improved ED with stimulated eNOS activities, as well as upregulated NO levels, BH4 content, and eNOS dimer/(dimer+monomer) ratio in the cardiac tissues. XJEK downregulated ET-1, Ang II, and ADMA content obviously compared to sham group. In conclusion, XJEK may exert the protective effects on MI rats and could continuously ameliorate ED and reverse CR with the progression of MI over time.

RESUMEN

AIM: Cardiovascular diseases, such as coronary heart disease and myocardial infarction (MI) are currently considered as the leading causes of death and disability. The aim of the present study is to investigate the effects of Xin-Ji-Er-Kang (XJEK) on kidney injury and renal oxidative stress. In addition, the associated mechanism involved in these processes was examined in an MI model, and particularly focused on the nuclear factor erythroid 2-related factor (NRF2)/heme oxygenase-1 (HO-1) pathway. MATERIALS AND METHODS: A total of 138 Sprague-Dawley rats were used in the present study. The control group was designated as 0 wk (n = 8). A total of 3 phases (2, 4, 6 wk) of administration were used in the sham-operated groups (sham, n = 10), MI groups (MI, n = 10), MI + XJEK groups (XJEK, n = 10) and MI + fosinopril groups (fosinopril, n = 10). Additional 10 rats were used to evaluate the infarct area. At 2, 4 or 6 wk post-MI, the hemodynamic parameters were monitored, the rats were sacrificed, then blood, heart and renal tissues were collected for furtherly analysis. RESULTS: The results indicated that XJEK administration continuously ameliorated renal hypertrophy index, blood urea nitrogen and cystatin C concentrations. XJEK further improved post-MI cardiac function by limiting scar formation and caused a downregulation in the hemodynamic parameters at the end of 2 and 4 wk. The hemodynamic parameters were upregulated after 6 wk treatment with XJEKcompared with those noted in the MI groups. Similarly, XJEK treatment for 2 wk potentiated Nrf2 nuclear translocation and HO-1 expression and inhibited the deficiency of nuclear Nrf2 and HO-1 at 6 wk post-MI compared with that of the MI groups, indicating the attenuation of the renal oxidative stress condition. The levels of malondialdehyde and angiotensin II (Ang II) in plasma and renal tissues, as well as the levels of aldosterone, 8-hydroxydeoxyguanosine, angiotensin II type 1 receptor and NADPH Oxidase-4 in the kidney tissue significantly decreased following XJEK treatment for 6 wk. In addition, the XJEK treatment groups revealed a significant upregulation in the activity of superoxide dismutase and in the total antioxidant capacity activity compared with those noted in the corresponding MI groups. CONCLUSION: These results demonstrated that progressive nephropathy in MI rats was associated with intrarenal activation of the renin-angiotensin-aldosterone system. Concomitantly, this process was associated with oxidative stress and impaired Nrf2 activation. The improvement in the severity of nephropathy by XJEK in this model may be associated with the reversal of these abnormalities.

RESUMEN

BACKGROUND: Xin-Ji-Er-Kang (XJEK) is a Chinese herbal formula that has beenreported to exert effective protection against cardiovascular diseases, such as hypertension and myocarditis. OBJECTIVE: The aim of the present study was to investigate the effect of XJEK on high-salt-induced hypertensive mice and its possible mechanism. METHODS: The model of hypertension was established through a high-salt diet. Sixty male Kunming mice were randomized into six groups, namely the Control, Model, Low-dose XJEK, Middle-dose XJEK, High-dose XJEK and Fosinopril groups (n=10 per group). Different steady interventions were given to each group: 0.9% Sodium chloride was added to the diet of the Control group and 8% sodium chloride to the diet of the other five groups from the very beginning. An additional 4, 8 and 12 g/kg/day XJEK were intragastrically administered to the Low-dose, Middle-dose and High-dose XJEK groups, respectively, and 2 mg/kg/day fosinopril to the fosinopril group, from the start of week 5. Systolic blood pressure (SBP) was measured weekly from weeks 1 to 8 using the tail-cuff method. At the end of week 8, left ventricular (LV) systolic pressure, LV end-diastolic pressure and rate of rise of LV pressure were examined using a TransonicScisense catheter (Transonic Systems Inc,Ithaca, NY,USA). Endothelium-dependent relaxations induced by acetylcholine were observed in an isolated thoracic aorta ring. Serum and heartsweresampled for the measurement of the following indexes:Serum nitric oxide (NO), superoxide dismutase (SOD) activity and malondialdehyde (MDA) content (determined by colorimetricanalysis); serum angiotensin II(Ang II), endothelin-1, endothelial NO synthase (eNOS), asymmetric dimethylarginine (ADMA), tetrahydrobiopterin (BH4) concentration and l-arginine (determined by enzyme-linked immunosorbent assay); heart to body weight (HW/BW) ratio; myocardial morphological change (determined by HE and VG staining); myocardial eNOS expression (determined by immunofluorescence), and myocardial endothelin receptor A (ETA) expression (determined by western blotting). RESULTS: Statistical data showed that the HW/BW ratio was significantly decreased in the drug treatment group. XJEK treatment could improve the heart systolic and diastolic function and ameliorate hemodynamic parameters and vascular remodeling indexes. Colorimetric results showed that, compared with the model group, XJEK increased serum SOD, NOlevels, and decreased those of serum MDA and Ang II. XJEK reverted changes in cardiac pathology, decreased the myocardial cross-sectional area, collagen volume fraction and perivascular collagen area and improved endothelial dysfunction (ED) by promoting eNOS activity, enhancing NO bioavailability, increasing the expression of BH4 and decreasing ETA content. In addition, treatment with XJEK decreased ADMA content in the myocardium. CONCLUSION: In conclusion, XJEK mitigates cardiac remodeling in high-salt-induced hypertensive mice. The potential mechanism involves improved oxidative stress and endothelial dysfunction, independently of ameliorating BP.

RESUMEN

Lactobacillus rhamnosus GG (LGG) performs many physiological functions, but the fermentation time is long when fermented milk is prepared using LGG alone. To shorten the fermentation time, we analyzed the nutrient requirement profiles of LGG. Based on nutrient requirement profiles, we evaluated the effects on the fermentation time, quality, and sensory properties of unmodified cow's milk fermented by LGG alone. According to the consumption and necessary patterns of amino acids and those of purine, pyrimidine, vitamins, metal ions, and nutrients essential to LGG, we selected Cys, Ser, Arg, Pro, Asp, Glu, guanine, uracil, and xanthine with which to supplement milk. Compared with fermented milk prepared using LGG alone in unmodified milk, the fermentation time of supplemented milk was shortened by 5 h. Viable cell counts, titratable acidity, and water-retaining capability of the fermented milk were improved by addition of nutrient supplements. Supplementation with nutrients did not obviously change the sensory and textural characteristics of fermented milk.
