[Mechanism of heat-clearing prescriptions in alleviating type 2 diabetes mellitus:a review].

Type 2 diabetes mellitus(T2DM), a common chronic metabolic disease, is often accompanied by internal heat syndrome. Heat-clearing prescriptions are widely used to treat different heat syndromes of T2DM from the aspects of clearing stagnant heat, excess heat, damp heat, phlegm heat, and heat toxin, demonstrating remarkable effects. The mechanism of blood sugar-lowering agents has always been a hotspot of research. Recently, the basic studies of heat-clearing prescriptions from different perspectives have been increasing year by year. To clarify the mechanisms of heat-clearing prescriptions and find specific mechanisms, we systematically reviewed the basic studies of heat-clearing prescriptions commonly used for the treatment of T2DM in the past decade, intending to provide a reference for related research.

Effect of Gegen Qinlian Decoction on Hepatic Gluconeogenesis in ZDF Rats with Type 2 Diabetes Mellitus Based on the Farnesol X Receptor/Ceramide Signaling Pathway Regulating Mitochondrial Metabolism and Endoplasmic Reticulum Stress.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a kind of disorder of glucose and lipid metabolism with the main clinical manifestation of long-term higher blood glucose level than the normal value. Farnesol X receptor (FXR)/ceramide signaling pathway plays an important role in regulating cholesterol metabolism, lipid homeostasis, and the absorption of fat and vitamins in diet. Gegen Qinlian Decoction (GQD) is a classical herbal formula, which has a good clinical therapeutic effect on diabetes-related metabolic syndrome. OBJECTIVE: To investigate the effect of Gegen Qinlian Decoction (GQD) on hepatic gluconeogenesis in obese T2DM rats based on the FXR/ceramide signaling pathway regulating mitochondrial metabolism and endoplasmic reticulum stress (ERS). METHODS: ZDF (fa/fa) rats were fed with high-fat diet to establish the T2DM model; GQD was given to T2DM model rats by gavage; changes of the general state and body weight of rats were recorded; fasting blood glucose was detected; blood insulin, blood ceramide, glycosylated hemoglobin in blood, acetyl CoA in liver mitochondria, and bile salt lyase in intestinal tissue were detected by ELISA. The content of T-ß-MCA in blood was detected by LC-MS; the content of glycogen in liver tissue was detected by PAS staining; the expression of FXR, Sptlc2, and Smpd3 in ileum tissue, P-PERK, ATF6α, GRP78 BIP, and P-IRE1 in the liver, and CS and PC protein in liver mitochondria was detected by immunohistochemistry and western blot assay. The mRNA expression levels of FXR, Sptlc2, and Smpd3 in the ileum, PERK, ATF6α, GRP78 BIP, and IRE1 in the liver, and CS and PC in liver mitochondria were detected by qRT-PCR. RESULTS: GQD can improve the general state of T2DM rats, slow down their weight gain, reduce the levels of fasting blood glucose, fasting insulin, glycosylated hemoglobin, blood ceramide, bile salt hydrolase in intestinal tissue, and acetyl CoA in liver mitochondria of T2DM rats, and increase the contents of liver glycogen and T-ß-MCA in blood of T2DM rats. At the molecular level, GQD can inhibit the expression levels of FXR, Sptlc2, and Smpd3 in the ileum of T2DM rats and the protein and mRNA expression levels of oxidative stress-related factors in the liver. At the same time, GQD can increase the expression of CS and reduce the expression of PC in liver mitochondria of T2DM rats. CONCLUSION: GQD can inhibit the FXR/ceramide signaling pathway, regulate endoplasmic reticulum stress, enhance the CS activity of liver mitochondria, reduce the acetyl CoA level and PC activity of liver mitochondria, inhibit hepatic gluconeogenesis, protect islet ß-cells, and control blood glucose.

Integrated Traditional Chinese and Western medicine for ulcerative colitis with diabetes: A protocol for systematic review and meta-analysis.

BACKGROUND: This study aimed to access the efficacy and safety of integrated Traditional Chinese and Western medicine treatment for patients with ulcerative colitis (UC) combined diabetes. METHODS: This protocol adheres to the preferred reporting items for systematic reviews and meta-analysis protocol statement. We plan to search 8 electronic databases to identify qualifying studies published from database inception until December 1, 2020. The software of EndNote reference manager (X9) will be used to study selection. A pre-developed standardized data collection form will be used to extract from all eligible studies. For included studies, the quality will be assessed by Cochrane Risk of bias tool. The RevMan 5.3 software (Copenhagen: The Nordic Cochrane Centre, The Cochrane Collaboration, 2014) developed by the Cochrane Collaboration will be used for all statistical analysis. If possible, meta-analysis will be undertaken for each of the outcomes. For continuous variable data, we will used mean differences with 95% confidence intervals (CIs) as summary statistics. For dichotomous variable data, we will calculate Mantel-Haenszel odds ratio with 95% CIs as summary statistics from the numbers of events in control and intervention groups. We will consider a result to be statistically significant if P < .05. If outcomes cannot be meta-analyzed, we will performer a descriptive analysis. RESULTS: This study will be performed to test the efficacy and safety of integrated Traditional Chinese and Western medicine treatment for patients with UC combined diabetes. CONCLUSION: The results of our study will be published in a peer-reviewed journals, and we will promotion results in domestic and foreign conferences. REGISTRATION NUMBER: INPLASY2020120087. ETHICS AND DISSEMINATION: As a systematic review and meta-analysis which based on previously published literature, ethical approval, and informed consent from patients are not required.

[Analysis on regularity of prescriptions in "a guide to clinical practice with medical record" for diarrhoea based on traditional Chinese medicine inheritance support system].

To analyze the regularities of prescriptions in "a guide to clinical practice with medical record" (Ye Tianshi) for diarrhoea based on traditional Chinese medicine inheritance support system(V2.5), and provide a reference for further research and development of new traditional Chinese medicines in treating diarrhoea. Traditional Chinese medicine inheritance support system was used to build a prescription database of Chinese medicines for diarrhoea. The software integration data mining method was used to analyze the prescriptions according to "four natures", "five flavors" and "meridians" in the database and achieve frequency statistics, syndrome distribution, prescription regularity and new prescription analysis. An analysis on 94 prescriptions for diarrhoea was used to determine the frequencies of medicines in prescriptions, commonly used medicine pairs and combinations, and achieve 13 new prescriptions. This study indicated that the prescriptions for diarrhoea in "a guide to clinical practice with medical record" are mostly of eliminating dampness and tonifying deficienccy, with neutral drug property, sweet, bitter or hot in flavor, and reflecting the treatment principle of "activating spleen-energy and resolving dampness".

[Clinical application of acupunctural anesthesia with new combination principle of acupoints in supratentorial craniocerebral operation of tumor in vital functional area or deep site of brain].

OBJECTIVE: To summarize the experience in applying acupunctural anesthesia (AA) with new combination principle (NCP) of acupoints in supratentorial craniocerebral operation of tumor in functional area or deep site of brain. METHODS: With the acupoints selection of AA changed from the previous combination principle of near segmental and peri-operational region to the NCP of near-remote along corresponding meridian, craniotomy was carried out under AA in 23 patients. RESULTS: Operation was performed successfully in all the patients, 82.6% of them with the effectiveness reaching I A grade. In those operated on the vital functional area, such as central anterior/posterior gyrus and language center, the accidental functional injury could be well prevented. CONCLUSION: AA with NCP of acupoints has satisfactory effect in supratentorial craniocerebral operation of functional area or deep site of brain, it is especially valuable in monitoring the effect of operation on function of around normal cerebral area to avoid accident injury.
