Efficacy and safety of Fuzheng Huayu tablet on persistent advanced liver fibrosis following 2 years entecavir treatment: A single arm clinical objective performance criteria trial.

ETHNOPHARMACOLOGICAL RELEVANCE: Antiviral therapy can alleviate liver fibrosis in chronic hepatitis B, but it has a limited effect on advanced liver fibrosis/cirrhosis. Traditional Chinese medicine (TCM), particularly FuZheng HuaYu (FZHY) tablet, appears to have an antifibrotic effect, but its improving resolution of hepatitis b virus (HBV) -associated advanced fibrosis and experienced anti-viral treatment has not been investigated. AIM OF THE STUDY: To observe the safety and efficacy of adjunctive FZHY on the HBV-associated cirrhosis patients who received 2 years of entecavir but still with advanced fibrosis. METHODS: An open-label, multicentre, single arm trial. 251 patients were included and treated with TCM consisted of FZHY tablets 1.6 g and granules, three times a day in addition to entecavir 0.5 mg daily for an additional 48 weeks. Primary outcome was regression of fibrosis (the proportion of patients with a 1-point decrease in the Ishak liver fibrosis score from baseline to week 48). RESULTS: Fibrosis regression occurred in 94 of 184 patients with paired liver biopsy (51.09%, 95% CI: 43.9～58.0). In 132 compensated cirrhosis patients (Ishak score ≥5), 56.06% (74/132, 95% CI: 47.5～64.2) showed fibrosis regression and reached the goal of 54% (15% more than entecavir mono-therapy). 10 patients occurred adverse reaction, most of them were mild, and all recovered or achieved remission. CONCLUSIONS: The combination therapy of FZHY, TCM granules and ETV could regress the liver fibrosis in the patients with HBV cirrhosis, who experienced 2 years of ETV treatment, and it is safe and well tolerated.

Respiratory Muscle Training Reduces Respiratory Complications and Improves Swallowing Function After Stroke: A Systematic Review and Meta-Analysis.

OBJECTIVE: To investigate whether respiratory muscle training is capable of reducing the occurrence of respiratory complications and improving dysphagia (swallowing or cough function) after stroke. DATA SOURCES: Cochrane Library, Excerpta Medical Database (EMBASE), PUBMED, and Web of Science were searched for studies published in English; the China Biology Medicine (CBM), China Science and Technology Journal Database (VIP), China National Knowledge Infrastructure (CNKI), and Wanfang Database were searched for studies published in Chinese up to August 10, 2021. STUDY SELECTION: Eleven randomized control trials (RCTs) (N=523) met the inclusion criteria were included in this systematic review. DATA EXTRACTION: Data and information were extracted by two reviewers independently and disagreements was resolved by consensus with a third coauthor. Primary outcome was the occurrence of respiratory complications, secondary outcomes would be represented by swallowing and cough function. The quality of each included RCT were assessed by Cochrane risk-of-bias criteria and the GRADE evidence profile was provided to present information about the body of evidence and judgments about the certainty of underlying evidence for each outcome. DATA SYNTHESIS: Respiratory muscle training reduced the risk of respiratory complications (relative risk, 0.51; 95% confidence interval [CI], 0.28-0.93; I2=0%; P=.03; absolute risk difference, 0.068; number need to treat, 14.71) compared with no or sham respiratory intervention. It also decreased the liquid-type Penetration-Aspiration Scale scores by 0.81 (95% CI, -1.19 to -0.43; I2=39%; P<.0001). There was no significant association between respiratory muscle training and Functional Oral Intake Scale (FOIS) scores, cough function: increased FOIS scores by 0.47 (95% CI, -0.45 to 1.39; I2=55%; P=.32), decreased peak expiratory cough flow of voluntary cough by 18.70 L per minute (95% CI, -59.74 to 22.33; I2=19%; P=.37) and increased peak expiratory cough flow of reflex cough by 0.05 L per minute (95% CI, -40.78 to 40.87; I2=0%; P>.99). CONCLUSION: This meta-analysis provided evidence that respiratory muscle training is effective in reducing the risk of respiratory complications and improving dysphagia by reducing penetration or aspiration during swallowing liquid bolus after stroke. However, there was no sufficient evidence to determine that respiratory muscle training improves cough function. Additional multicenter studies using larger patient cohorts are required to validate and support these findings. Furthermore, long-term follow-up studies should be performed to measure outcomes, while avoiding bias due to confounding factors such as heterogeneity of the etiologies of dysphagia.

[Research progress on the regulation of phenolic compounds of traditional Chinese herbs on oral microbes].

Phenolic compounds are widely found in natural Chinese medicinal plants and have excellent pharmacological properties, such as antioxidation and anti-inflammation. They are the main pharmacological components of many medicinal Chinese herbs. Oral microbiota, especially its composition and metabolism, is highly related to the balance of oral microecology and plays a key role in the occurrence and development of oral diseases. Recent studies have shown that phenolic compounds of traditional Chinese herbs can prevent and treat oral diseases, such as caries, periodontal disease, and oral mucosal infection, by regulating the composition, metabolites, and virulence of oral microorganisms. This review will summarize and discuss the regulation of phenolic compounds on oral microbes.

[Studies on extraction technology of total flavonoids from flower of Eriobotrya japonica].

OBJECTIVE: To study the optimum extraction technology of total flavonoids from Flower of Eriobotrya japonica. METHODS: To screen the best extraction technology by single-factor and orthogonal experiment according to the content of total flavonoids. RESULTS: The optimum conditions were as follows: we extracted three times at 60 degrees C, each time for 1 h and the ratio of raw materials and solution was 1:10. CONCLUSIONS: The extracting method is fit for the extraction of total flavonoids from Flower of Eriobotrya japonica. It can also provide a scientific basis for manufacture.

[Studies on the chemical constituents of the aerial parts of Seseli mairei].

OBJECTIVE: To study the chemical constituents of the aerial parts of Seseli mairei Wolf. METHODS: The chemical constituents have been separated with manifold chromatography methods, and their structures were determined hy spectral analysis. RESULTS: Thirteen compounds were isolated and identified as sphondin (I), hergapten (II), isopimpinellin (III), umbelliferone (IV), chrysosptertin B (V), apiin (VI), rutin (VII), quercetin (VIII), ferulic acid (IX), falcarindiol (X), docosanol (XI), beta-sitosterol (XII), daucosterol (X III). CONCLUSION: All these compounds were isolated from the aerial parts of Seseli mairei Wolf. for the first time.
