Gegen Qinliantang Ameliorates Glucose and Lipid Metabolism Disorders in Rat Model of Catch-up Growth by Regulating SIRT1/PGC1α/Nrf1 Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo investigate the effect of Gegen Qinliantang on glucose and lipid metabolism in the rat model of catch-up growth （CUG） induced by a high-fat diet and the underlying mechanism. MethodA total of 60 SD rats were randomized into a normal control group （n=18） and a modeling group （n=42）. The rat model of CUG was established with a restricted diet followed by a high-fat diet， and the changes of general status and body weight were observed. The levels of fasting blood glucose （FBG）， fasting insulin （FINS）， triglyceride （TG）， and total cholesterol （TC） were measured in 6 rats in each group at the end of the 4th and 8th week， respectively. The homeostasis model assessment of insulin resistance index （HOMA-IR） was calculated， and the insulin sensitivity and body composition changes of CUG rats were evaluated. The successfully modeled rats were assigned into 6 groups： normal control， model， high-， medium-， and low-dose Gegen Qinliantang （2.5， 5， 10 g·kg-1）， and pioglitazone （3.125 mg·kg-1）. The rats were administrated with corresponding drugs by gavage for 6 weeks， and the normal control group and model group were administrated with the same amount of normal saline. During the experiment period， the changes of body weight were recorded， and the FBG， FINS， HOMA-IR， TG， and TC were determined at the end of the experiment. Hematoxylin-eosin （HE） staining was employed to observe the pathological changes of skeletal muscle in rats. The levels of reactive oxygen species （ROS） and malondialdehyde （MDA） in the skeletal muscle were measured strictly according to the manuals of the reagent kits. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was performed to measure the mRNA levels of silencing information regulator 1 （SIRT1）， peroxisome proliferator-activated receptor-gamma coactivator1α （PGC1α）， and nuclear respiratory factor 1 （Nrf1） in the skeletal muscle. Western blot and immunohistochemistry were employed to assess the expression of SIRT1， PGC1α， and Nrf1 in the skeletal muscle. ResultCompared with the normal control group， the model group presented elevated levels of FBG， FINS， TG， and TC （P<0.05， P<0.01）， increased HOMA-IR （P<0.01）， increased diameter of muscle fibers and adipocytes between muscle cells in the skeletal muscle， rising levels of ROS and MDA in the skeletal muscle （P<0.01）， and down-regulated mRNA and protein levels of SIRT1， PGC1α， and Nrf1 （P<0.05， P<0.01）. Compared with the model group， Gegen Qinliantang （especially the medium and high doses） and pioglitazone decreased the body weight， FINS， HOMA-IR， and TG （P<0.05， P<0.01） and reduced interstitial components such as intermuscular fat in the skeletal muscles and the diameter of muscle fibers. Furthermore， the drugs lowerd the levels of ROS and MDA （P<0.05， P<0.01） and up-regulated the mRNA and protein levels of SIRT1， PGC1α， and Nrf1 （P<0.05， P<0.01） in the skeletal muscle. ConclusionGegen Qinliantang can ameliorate the glucose and lipid metabolism disorders and insulin resistance in CUG rats by regulating the SIRT1/PGC1α/Nrf1 signaling pathway.

Understanding of the relations of metabolic syndromes and abnormal Bianzheng based on the physiological characteristics of the liver and spleen in children / 国际中医中药杂志

Bianzheng was a special gasification law, closely related to metabolism Physiologically. The children's Bianzheng was the internal basis for sound physical and mental development and the dynamic balance of the five internal organs. As to the pathology, children's Bianzheng disorders had an adverse effect on the body. The ancient books found that children's Bianzheng disorders were closely related to the dysfunction of liver and spleen. It was manifested as malnutrition, developmental disorders, and even metabolic syndrome in adulthood. The principle of soothing the liver, relieving depression and strengthening the spleen were proposed to treat the metabolic syndrome, in order to enrich the Traditional Chinese Medicine (TCM) theoretical understanding of the metabolic syndrome. The prevention and treatment ideas provide theoretical reference.

Correlation between life quality and disease uncertainty of patients with high risk of diabetic foot / 现代临床护理

Objective To investigate the relationship between the life quality and the disease uncertainty of the patients with high risk of diabetic foot. Methods The data of 235 patients with high risk of diabetic foot were selected by the convenience sampling method, using the life quality scale for patients with type 2 diabetes mellitus(DMQLS revised edition) and the uncertainty of disease scale (MUIS). Results The total score on life quality in the diabetic patients with high risk was (138.04 ± 7.32), which was at a high level. The psychological dimension ranked on the top in terms of the score, following by physiological dimension, social dimension, disease dimension and satisfaction dimension. The overall score on the uncertainty was (100.09 ±6.89), which was at intermediate level. The dimension of unpredictability ranked on the top, followed by uncertainty, complexity and lack of information. Pearson correlation analysis showed that the uncertainty together with its four dimension was negatively related with quality of life (all P <0.05). Conclusions The life quality in the patients with high risk of diabetes is generally poor and their sense of uncertainty is at the moderate level. The quality of life is negatively correlated with the uncertainty of disease. So reducing the disease uncertainty is helpful for the improvement of the quality of life.

Clinical observation of enteral nutrition support in patients with acute exacerbation of chronic obstructive pulmonary disease / 肠外与肠内营养

Objective:To investigate the clinical effect of enteral nutrition (EN) on patients with acute exacerbation of chronic obstructive pulmonary disease (COPD).Methods:96 cases of acute exacerbation of COPD patients admitted to our hospital from January 2015 to December 2016 were randomly divided into observation group (48 cases) and control group (normal diet,48 cases).The patients in two groups were given anti-infection and other symptomatic treatments equally.The serum protein levels and pulmonary function in the two groups were compared after 2 weeks.Furthermore,antibiotic use durations,hospitalization days and the re-admission rates within 3 months were observed and compared between two groups.Results:The serum albumin and pre-albumin levels,FEV1 and FEV1/FVC in the observation group were significantly elevated in comparison with those in the control group.And the antibiotic use durations,hospitalization days and the re-admission rates within 3 months remarkably decreased in the observation group (P ＜ 0.05).Conclusion:Enteral nutrition could improve the nutritional status and pulmonary function in patients with acute exacerbation of COPD,shortening the length of hospital stay and the durations of antibiotic use and reducing the rates of re-admission.Enteral nutrition may be worth applying widely in clinical COPD patients in future.

Objective:To explore the effects of effective nursing intervention on ICU central venous catheter related infection. Methods:A retrospective survey method was adopted. A total of 200 patients with central venous catheter received the conventional nursing care before 2013 were selected as control group, and meanwhile 200 patients from Jan 2013 to Dec 2014 with central venous catheter received the nursing intervention were select as observation group, and then the incidence rate of central venous catheter related infection was compared. Result:The infection rate of three ways of intubation and total infection rate in observation group were lower than those in control group (P<0.05) . Conclusion:Effective nursing intervention can reduce the incidence rate of catheter related infections.
