[Randomized controlled trial outcome indicators of traditional Chinese medicine for gastrointestinal dysfunction in sepsis in recent two years].

The purpose of the study is to analyze the outcomes of randomized controlled trial(RCT) of Chinese herbal medicine formula(CHMF) in the treatment of gastrointestinal dysfunction in sepsis in recent two years. We systematically searched four Chinese databases, three English databases, and two clinical trial registries to analyze the reports of outcome indicators of clinical trials, and evaluated the risk of bias by using the ROB tool of Cochrane Collaboration. After screening, 55 clinical RCTs were included. The results showed that the current clinical studies of gastrointestinal dysfunction in sepsis reported the efficacy and safety indicators. The efficacy indicators included APACHE Ⅱ scores, gastrointestinal dysfunction scores, bowel sound scores, and inflammatory indicator such as C-reactive protein and procalcitonin. The safety indicators mainly include gastrointestinal reactions, skin reactions, and other adverse events and adverse reactions. However, there was no distinction between primary and secondary outcomes. The relevant indicators of health economics were not reported, and the quality of research methodology was poor. Therefore, we suggest that future researchers should be well prepared in the top-level design stage and actively construct the core outcome set, so as to improve the quality of clinical trials.

Mitochondrial Dysfunction and Diabetic Nephropathy: Nontraditional Therapeutic Opportunities.

Diabetic nephropathy (DN) is a progressive microvascular diabetic complication. Growing evidence shows that persistent mitochondrial dysfunction contributes to the progression of renal diseases, including DN, as it alters mitochondrial homeostasis and, in turn, affects normal kidney function. Pharmacological regulation of mitochondrial networking is a promising therapeutic strategy for preventing and restoring renal function in DN. In this review, we have surveyed recent advances in elucidating the mitochondrial networking and signaling pathways in physiological and pathological contexts. Additionally, we have considered the contributions of nontraditional therapy that ameliorate mitochondrial dysfunction and discussed their molecular mechanism, highlighting the potential value of nontraditional therapies, such as herbal medicine and lifestyle interventions, in therapeutic interventions for DN. The generation of new insights using mitochondrial networking will facilitate further investigations on nontraditional therapies for DN.

Probiotics, prebiotics, and synbiotics for the improvement of metabolic profiles in patients with chronic kidney disease: A systematic review and meta-analysis of randomized controlled trials.

This systematic review and meta-analysis of randomized controlled trials (RCTs) was performed to quantify the effects of probiotic, prebiotic, and synbiotic supplementation on biomarkers of inflammation and oxidative stress, as well as lipid profiles among patients with chronic kidney disease (CKD). Electronic databases, including PubMed, the Cochrane Database, and the Web of Science were searched from January 1, 2000, to May 15, 2019. All RCTs that investigated the effect of prebiotics, probiotics, and synbiotics on a circulating (serum and plasma) inflammatory marker (C-reactive protein [CRP]), oxidative stress indicators (malondialdehyde [MDA], glutathione [GSH], and total anti-oxidant capacity [TAC]); and lipid profiles (total cholesterol [TC], triglycerides [TG], low-density lipoprotein cholesterol [LDL-c], and high-density lipoprotein cholesterol [HDL-c]) among patients with CKD were included. Data were pooled and expressed as a standardized mean difference (SMD) with a 95% confidence interval (CI). The protocol for this meta-analysis is registered with PROSPERO; No. CRD42019139090. Thirteen trials that included 671 patients were identified for analysis. The methodological quality varied across studies. Meta-analysis indicated that microbial therapies significantly reduced CRP (SMD, -0.75; 95% CI, -1.03 to -0.47; p = 0.000), MDA (SMD, -1.06; 95% CI, -1.59 to -0.52; p = 0.000), TC (SMD, -0.33; 95% CI, -0.52 to -0.13; p = 0.000), and LDL-c (SMD, -0.44; 95% CI, -0.86 to -0.02; p = 0.000) levels; they also increased the GSH (SMD, 0.44; 95% CI, 0.25 to 0.65; p = 0.000), TAC (SMD, 0.61; 95% CI, 0.07 to 1.15; p = 0.000), and HDL-c (SMD, 0.45; 95% CI, 0.03 to 0.87; p = 0.000) levels in CKD patients, as compared to the placebo groups; however, there was no statistically significant TG concentration among patients with CKD. Subgroup analyses showed that other key factors, such as the duration of intervention, participants' baseline body mass index (BMI), type of intervention, and age, had an effect of microbial therapies on outcomes. This meta-analysis supports the potential use of probiotic, prebiotic, and synbiotic supplements in the improvement of established biomarkers of inflammation and oxidative stress, as well as lipid profiles among patients with CKD, which are well-known cardiovascular risk factors. Further research into these interventions should consider the limitations of our study to explore the effect of long-term administration of these supplements in the CKD population.

Tripterygium and its extracts for diabetic nephropathy: Efficacy and pharmacological mechanisms.

Diabetic nephropathy (DN) is a common but intractable diabetic microvascular complication. Tripterygium, a Chinses herb, has been proven to be effective for DN treatment. In this review, the efficacy and pharmacological mechanism of tripterygium and its extracts on DN is elucidated. Tripterygium and its extracts could effectively reduce urine protein and protect renal function. Its pharmacological mechanism involves anti-inflammation, anti-oxidation, anti-glomerulosclerosis and anti-fibrosis, which is achieved by balancing the Th1/Th2 cells, regulating macrophage infiltration, and regulating the following pathways: p38 MAPK, NF-κB, TGF-ß, Wnt/ß-catenin, Akt and Notch1. Although tripterygium and its extracts may result in some adverse effects, including liver-function damage, gastrointestinal reaction, menstrual disorders, and reproductive problems, they are considered good alternative medicines for DN if used with caution and in the proper manner.

The effect of probiotic and synbiotic supplementation on biomarkers of inflammation and oxidative stress in diabetic patients: A systematic review and meta-analysis of randomized controlled trials.

The role of gut microbiota in the management of diabetes has been shown. Several current trials are investigating the effect of probiotics and prebiotics, which are widely used to modulate intestinal microbiota, on inflammatory factors and biomarkers of oxidative stress in diabetic patients; however, their findings are controversial. The aim of the current meta-analysis was to evaluate the effects of probiotic and synbiotic supplementation on levels of serum high-sensitivity C-reactive protein (hs-CRP) and biomarkers of oxidative stress in diabetic patients. We searched the PubMed, Web of Science, and The Cochrane Library databases from the inception to October 31, 2018. Randomized controlled trials (RCTs) which reported the effect of probiotics or synbiotics on circulating (serum and plasma) inflammatory marker (hs-CRP) and oxidative stress indicators (malondialdehyde [MDA], glutathione [GSH], nitric oxide [NO], and total antioxidant capacity [TAC]) among patients with diabetes were included. Eligible studies were assessed for risk of bias and subjected to qualitative and quantitative synthesis using either fixed- or random-effects models accounting for clinical heterogeneity. Our meta-analysis identified 16 eligible RCTs (n = 1060). The methodological quality varied across these trials. Pooled data from these trials demonstrated that probiotic and synbiotic consumption significantly decreased hs-CRP level (standardized mean difference [SMD]=-0.38; 95% confidence interval [CI]:-0.51,-0.24; P = 0.000) and MDA (SMD=-0.61; 95% CI: -0.89, -0.32; P = 0.000) in diabetic patients compared to those in subjects receiving placebos. In addition, probiotic and symbiotic supplementation was found to increase TAC (SMD = 0.31; 95% CI: 0.09, 0.52; P = 0.006), NO (SMD, 0.62; 95% CI, 0.25 to 0.99; P = 0.001) and GSH (SMD = 0.41; 95% CI: 0.26, 0.55, P = 0.000) levels. The results of this systematic review and meta-analysis suggest that probiotic and synbiotic supplementation may help to improve biomarkers of inflammation and oxidative stress in diabetic patients. Further studies are needed to develop clinical practice guidelines for the management of inflammation and oxidative stress in these patients.

Research Progress on Non-Drug Treatment for Blood Glucose Control of Type 2 Diabetes Mellitus.

Type 2 diabetes mellitus (T2DM) is one of the common endocrinology diseases that greatly affects the health care sector and economy. Application of hypoglycemic drugs has its own drawbacks and the use of non-drug therapy on treating T2DM has drawn much attention recently. This paper reviewed the research development of the non-pharmacological interventions on T2DM in recent years, including dietary therapy, exercise therapy, psychotherapy, acupuncture and moxibustion therapies and so on. The authors mentioned the problems in the research of non-drug treatment for blood glucose control of T2DM and put forward new ideas for the research in the future. Further well-designed trials with large sample size and long-term follow-up are needed to confirm current conclusions.

Medium-chain fatty acid nanoliposomes for easy energy supply.

OBJECTIVE: Developing a nanoliposome delivery system for an easy energy supply of medium-chain fatty acids (MCFAs) to improve oral doses and bioavailability. METHODS: Bangham's method and high-pressure microfluidization were used to prepare MCFA liposomes. The easy energy-supply property of MCFA nanoliposomes was estimated by the anti-fatigue experiments of mice including a weight-loaded swimming test and its corresponding parameters (serum urea nitrogen, blood lactic acid, and hepatic glycogen). For comparison, nanoliposomes without MCFAs and MCFAs not entrapped in nanoliposomes were used throughout. RESULTS: Compared with crude MCFA liposomes according to Bangham's method, the MCFA nanoliposomes made by high-pressure microfluidization exhibited great advantages in their characteristics, with a small average diameter (76.2 ± 34.7 nm), narrow size distribution (polydispersity index 0.207), high ζ-potential (-50.51 mV), great entrapment efficiency (70.5%) and drug loading (9.4%), and good stability. The high-dose group and the MCFA group (680 mg/kg) showed a longer weight-loaded swimming time (104 ± 29 min, P = 0.087, and 108 ± 11 min, P = 0.047, respectively) and significantly higher hepatic glycogen (16.40 ± 1.45 mg/g, P < 0.001 and 17.27 ± 2.13 mg/g, P < 0.001, respectively) than the control group (59 ± 11 min and 8.79 ± 2.76 mg/g, respectively). Moreover, serum urea nitrogen (891.5 ± 113.4 mg/L, P = 0.024, and 876.6 ± 70.8 mg/L, P = 0.015, respectively) and blood lactic acid (6.05 ± 1.40 mmol/L, P = 0.001, and 5.95 ± 1.27 mmol/L, P < 0.001, respectively) in the high-dose group and the group with an equivalent MCFA dose were significantly lower than those in the control group (1153.6 ± 102.5 mg/L and 12.53 ± 1.86 mmol/L, respectively). CONCLUSION: Similar to MCFAs, MCFA nanoliposomes prepared by high-pressure microfluidization showed a strong easy energy-supply property, which suggested that MCFA nanoliposomes could be a potential drug candidate for an easy energy supply.
