Dietary therapy of the herbal porridge improves the symptoms of functional dyspepsia: A randomized, double-blind, placebo-controlled, clinical trial.

This study (ISRCTN17174559) aimed to explore the efficacy and safety of a kind of herbal porridge (Hou Gu Mi Xi) on the clinical symptoms of functional dyspepsia (FD). This was a single-center, single-dose, prospective, double-blind, randomized controlled trial involving 64 participants with FD (35 cases and 29 controls) for 2 months of intervention and 1 month of follow-up. The 7-point Global Overall Symptom Scale (GOSS), 36-Item Short Form Survey (SF-36), and other indicators were assessed at baseline (day 0), at days 15, 30, and 60 of treatment, and at follow-up 1 month after the end of the intervention. Many participants with FD achieved remission of their epigastric symptoms at follow-up on the 90th day after treatment with herbal porridge compared to the placebo group (45.71% vs. 20.69%, p = .036). Furthermore, herbal porridge appeared to be effective in improving the quality of life of participants with FD, which was reflected in the rising SF-36 scores for physical role, bodily pain, emotional role, and mental health. Although adverse events were reported, there was no overall difference in the number of adverse events between the two groups (p = .578). Herbal porridge is another effective and safe method for improving the symptoms and quality of life in patients with FD.

Effects of Glucomannan Supplementation on Type II Diabetes Mellitus in Humans: A Meta-Analysis.

The hypoglycemic and lipid-lowering effects of glucomannan are widely known, and it is a potential effective treatment for type II diabetes. In this study, we evaluated the effects of glucomannan supplementation on blood-lipid-related indicators, blood-glucose-related indicators, blood pressure (BP), and body weight (BW) in patients suffering from type II diabetes. We searched databases including PubMed, Cochrane, the comprehensive biomedical research database (Embase), Web of Science, and China National Knowledge Infrastructure (CNKI) for literature on glucomannan and type II diabetes. Six randomized controlled trials (RCTs) were eligible (n = 440 participants) to be included in our analysis. Glucomannan not only reduced the total cholesterol (TC) (MD -0.38 [95% CI: -0.61, -0.15], p = 0.001) and low-density lipoprotein (LDL) levels (MD -0.35 [95% CI: -0.52, -0.17], p < 0.0001) compared with the control group, but also reduced the fasting blood glucose (FBG) (MD -1.08 [95% CI: -1.65, -0.50], p = 0.0002), 2 h postprandial blood glucose (P2hBG) (MD -1.92 [95% CI: -3.19, -0.65], p = 0.003), fasting insulin (FINS) (MD -1.59 [95% CI: -2.69, -0.50], p = 0.004), and serum fructosamine (SFRA) levels (SMD -1.19 [95% CI: -1.74, -0.64], p < 0.0001). Our analysis indicates that glucomannan is an effective nutritional intervention for type II diabetes.

Inverse Association Between Baseline Plasma Selenium Concentrations and Risks of Renal Function Decline in Hypertensive Adults.

BACKGROUND: The kidney has the highest level of selenium (Se) in the body, but the role of plasma Se in chronic kidney disease is uncertain. OBJECTIVE: We aimed to investigate the longitudinal association between baseline plasma Se and renal function decline in adults with hypertension and to explore possible effect modifiers. METHODS: This was a post hoc analysis of 935 men and women with hypertension aged 40 to 75 years from a folic-acid intervention trial (the China Stroke Primary Prevention Trial) in China. The baseline plasma Se was analyzed both as a continuous variable and as tertiles. The primary outcome was a rapid decline in renal function, defined as a mean decline in the estimated glomerular filtration rate of ≥ 5 mL/(min × 1.73 m2) per year. RESULTS: The median follow-up duration from baseline to outcome was 4.4 years. After multivariate adjustment, there was an inverse association between plasma Se and a rapid decline in renal function (per 10-unit increment; OR: 0.85; 95% CI: 0.73, 0.99). When the baseline plasma Se was assessed as tertiles, compared to the lowest tertile (<74.5 µg/L), a lower trend of the primary outcome was found in the second tertile (74.5 to < 89.4 µg/L; OR: 0.60; 95% CI: 0.34, 1.07) and the highest tertile (89.4 to <150 µg/L; OR: 0.42; 95% CI: 0.22, 0.80; Ptrend = 0.006). Furthermore, the Se-renal association was more pronounced among participants with folic acid treatment or with a higher baseline folate concentration (both Pinteraction values < 0.05). CONCLUSIONS: In this sample of Chinese adults with hypertension, baseline plasma Se concentrations were inversely associated with the risk of renal function decline. The China Stroke Primary Prevention Trial was registered at clinicaltrials.gov as NCT00794885.

Anthocyanin Consumption and Risk of Colorectal Cancer: A Meta-Analysis of Observational Studies.

This meta-analysis aimed to summarize the association between anthocyanin consumption and the risk of colorectal cancer. All relative articles were located on online databases, including PubMed, Embase, and the Cochrane Library as of June 11, 2018. Risk ratios (RRs) or odds ratio and their 95% confidence intervals (CIs) were calculated through the STATA 12.0 software package. A total of seven studies were included in the meta-analysis. A significant inverse association was found between total anthocyanin consumption and colorectal cancer risk (RR = 0.78; 95% CI, 0.64-0.95). Likewise, there was significant evidence of a relationship between anthocyanin intake and colorectal cancer in the colon site (RR = 0.81; 95% CI, 0.71-0.92); men (RR = 0.88; 95% CI, 0.81-0.95), and case-control studies (RR = 0.69; 95% CI, 0.60-0.78). A dose-response relationship was not found in this meta-analysis. The Grades of Recommendations Assessment, Development, and Evaluation quality in our study was very low. This meta-analysis indicates that anthocyanin consumption is inversely associated with the risk of colorectal cancer. Anthocyanins may play an active role in the prevention of colorectal cancer. Key teaching points: Some epidemiological studies found an inverse correlation between the high consumption of anthocyanins and low risk of colorectal cancer. Because of this structure, anthocyanins/anthocyanidins have a powerful capability of donating electrons, which can be characterized as antioxidant properties. Anthocyanins can also inhibit colon cancer by interfering in the cell cycle and inducing the effect of anti-proliferation and apoptosis. The formation of cytoplasmic vacuoles in cells also indicates that anthocyanins may induce autophagy. From the findings of nonrandomized controlled trials, anthocyanins may play an active role in the prevention of colorectal cancer.

Guidelines for parenteral and enteral nutrition support in geriatric patients in China.

The mortality and morbidity of geriatric patients is much higher than for younger patients, especially when critically ill. This may be attributed to a lower reserve capacity in most organs and systems, reduced ability to deal with physical stress and the presence of acute or chronic co-mobidities. Parenteral and enteral nutrition support can improve the clinical condition of the elderly patient and result in better outcomes, such as lower mortality, reduced hospital stay and reduced medical costs. There is a need to standardize nutrition screening and assessment, and the implementation of appropriate evidence based nutritional support of geriatric patients in China. The Chinese Medical Association's Group of Geriatric Nutrition Support has developed guidelines by researching the present situation in Chinese hospitals and by referring to the guidelines from both American Society for Parenteral and Enteral Nutrition (ASPEN) and the European Society for Clinical Nutrition and Metabolism (ESPEN).

[Effect of L-arginine on diabetic rats].

OBJECTIVE: To observe the effect of L-arginine on diabetic rats. METHODS: Forty adult male Lewis rats were randomized equally into diabetic and normal control groups, and the former rats were treated intraperitoneally with streptozotocin to induce diabetes mellitus. Seven days later, half of the diabetic and normal rats were injected intraperitoneally with L-arginine at the daily dose of 1 g/kg, while the remainder were given saline instead. All the rats were euthanized on 10 days after L-arginine or saline treatment, and their body weight, plasma protein, arginine and sugar, food and water intake were analyzed. RESULTS: Diabetic rats had obviously decreased body weight, plasma protein and arginine but increased blood sugar and food and water intakes in comparison with the control rats. L-arginine significantly increased plasma protein and arginine, decreased food and water intakes, but failed to prevent weight loss and blood sugar increment in diabetic rats as compared to their saline-treated counterparts. L-arginine supplementation did not result in any changes other than arginine elevation in the control rats. CONCLUSION: L-arginine supplementation can partially improve polydipsia and polyphagia and increase plasma protein in diabetic rats.

Chinese medicine compound Changtong oral liquid on postoperative intestinal adhesions.

AIM: The aim of this study was to observe the effect of a Chinese medicine compound Changtong oral liquid (CT) on tissue plasminogen activity (t-PA), plasminogen activator inhibitor (PAI), TGF-beta1 and hydroxyproline (OHP). METHODS: Two sets of animal experiments were performed in the present study. Forty New Zealand rabbits and 48 Sprague-Dawley (SD) rats were assigned randomly to one of the five groups: sham adhesion, adhesion with saline, adhesion with low dosage of the CT, adhesion with middle dosage of the CT and adhesion with high dosage of the CT. t-PA and PAI activity in plasma, OHP and TGF-beta1 expression in adhesion were investigated. Analysis of variance was used to test differences among groups. RESULTS: CT treatment increased plasma t-PA activity in rabbits but decreased TGF-beta1 activity in rats. The data were expressed from low to high dose respectively as follows: t-PA, 46.1+/-8.6 microkat/L, 59.6+/-10.1 microkat/L, 64.0+/-11.5 microkat/L; TGF-beta1 28+/-7.23%, 31+/-3.05%, 30+/-4.04%. There were significant differences compared with saline-treated animals (t-PA 26.4+/-5.1 microkat/L, TGF-beta1 54+/-5.51%). OHP content in cecum of rabbits from middle and high but not low dose of CT lowered significantly as compared with saline-treated rabbits, 0.3641+/-0.1373, 0.3348+/-0.0321, 0.2757+/-0.0497 mg/g vs 0.4183+/-0.0883 mg/g of protein, P>0.05, P<0.05, P<0.05 respectively. The rabbit plasma PAI activity and OHP content in abdominal wall had no difference in all groups. CONCLUSION: CT treatment significantly enhanced t-PA activity in rabbits, but decreased TGF-beta1 content in rats, OHP content in cecum of rabbits, and failed to affect the activity of PAI and OHP content in abdominal wall in rabbits, compared with saline group. The result suggests that CT could effectively prevent adhesions without interfering wound healing.
