Objective To observe the changes of body weight,fat mass and skeletal muscle mass of rats after 4 weeks of intermittent fasting,and explore relationship with autophagy in skeletal muscle,so as to provide theoretical basis for intermittent fasting.Method Twenty male Sprague Dawley rats were randomly divided into a control group (Con) and an intermittent fasting group (IF),each of 10.The rats of IF group were forbidden to eat food every Wednesday and Friday,and the body weight of both groups was recorded weekly.After 4 weeks,Dual-Energy X-Ray Absorption (DEXA) was used to analyze the body fat mass,then the bilateral soleus was separated to record the wet weight and measure the cross-sectional area of the soleus fibers by testing laminin with immunofluorescence confocal laser scanning microscope.The form of autophagic vacuole of soleus was observed using a transmission electron microscopy.The expression of autophagy-related protein LC3,p62 and regulating protein AMPK,pAMPK and ULK1 were measured using Western blotting.Result After 4 weeks of intermittent fasting,the weight and fat mass of IF were significantly lower than those of Con (P＜0.01),but there were no significant differences between them in wet weight and cross-sectional area of soleus (P＞0.05).The expressions of AMPK,p-AMPK,ULK1 in IF were significantly higher than those in Con (P＜0.01).Compared with Con,the expression of LC3-Ⅱ/LC3-Ⅰ of IF increased significantly,while the expression of p62 decreased significantly (P＜0.01).Conclusion Four weeks of intermittent fasting decreases the fat mass significantly,and control the weight efficiently.Intermittent fasting can maintain the skeletal muscle mass by promoting moderate autophagy through the AMPK-ULK1 pathway.It should be a potential lose weight method for further research.

Simplified interspecies nuclear transfer in mouse and bovine and the possibilities of the embryos reprogramming were developed. The zona and nucleus of the bovine oocyte were removed by pronase and bisection method respectively. When the skin fibroblast of mouse was fused with the nucleus-free oocyte of the bovine using 40?s and 1. 5 kv/cm direct current pulse, the rates of fusion and cleavage were 67. 44% and 30.23% respectively. Reconstructed heterogenous embryos finally developed to 8-cell stage when they were previously activated by ionomycin and 6-DMAP and subsequently cultured in press-made micro-well in the drop of the medium. Zona-free bisection method could be used for mouse heterogenous embryos cloning, and the micro well culture method could be used to avoid zona-free embryos aggregation.

Objective To explore the effect of suledexide on renal injury and podocalyxin expression of podocytes in STZ diabetic desoxycorticosterone acetate (DOCA)-hypertensive rats. Methods Wistar rats were subjected to subcutaneous injection of streptozotocin(STZ), followed by uninephrectomy and subcutaneous administration of DOCA. Diabetic and hypertensive rats were randomly allocated to treatment with sulodexide or a combination of sulodexide and telmisartan for 8 weeks. Blood pressure (BP), 24-hour urinary albumin were measured every 2 weeks. Blood and urinary samples were collected to detect biochemical indexes of plasma and urinary β-acetyl-β-D-glucosaminidase (NAG) at the end of the study. Immunohistochemistry (IHC), RT-PCR and Western blot were performed to examine the expression and distribution of podocalyxin. Results STZ +DOCA-treated rats progressively developed hypertension, albuminuria and hyperglycemia. Hyperlipidemia and hypoinsulinemia were found in diabetic and hypertensive rats compared with controls. Albuminuia was significantly reduced in sulodexide group at week 8 and sulodexide plus telmisartan group at week 6 and week 8. Blood pressure decreased in sulodexide plus telmisartan group. No significant effects on lipid and glucose metabolism were observed in all treated groups. Histopathological index increased in STZ+DOCA-treated rats, but was significantly lower in sulodexide group as well as sulodexide plus telmisartan group. The number of podocytes on glomerular cross-section of the four groups were comparable. Segmental loss and down-regulation of podocalyxin were detected in STZ+DOCA-treated rats, which were greatly attenuated by sulodexinde, meanwhile, combination treatment preserved more podocalyxin expression in glomeruli than sulodexide monotherapy. Conclusion Sulodexide effectively reduces albuminuria, prevents loss of podocyte podocalyxin and alleviates renal damage in STZ diabetic DOCA-hypertensive rats.

Venous thromboembolism (VTE) is a common disease with high risk for death and recurrence and can severely impair patients' quality of life.Despite decades of study on this troublesome disease,there are still many unsolved problems in terms of pathogenesis,diagnosis and treatment.Hundreds of articles with various study methods and controversial research results are published every year.Thus it is crucial to keep track of reliable recent studies and articles on VTE in order to better understand it and to handle intricate related clinical events more reasonably.We reviewed high-qualified articles and guidelines from recent years and summarized VTE-related progresses in this review.

Objective To analyze the application of modified abdomen pathway for excising the adrenal huge pheoehromocytoma.Methods One patient(male,42-year-old)had adrenal huge pheochromocytoma.The pheochromocytoma was about 15.0 cm×8.0 cm×7.0 cm.After 3 weeks' preparations,the patient was operated.The operation was made through the modified abdomen pathway for excision,without excising the transverse on peritoneal,and the interference to organs of peritoneal was reduced.The tumor on adrenal gland adhered kidney very tightly.Expanded radical excision including tumor,kidney,adrenal gland was applied.Results The operative time was 300 rain and the volume of bleeding was about 1000 ml.In the operation process,blood pressure of the patient was stable,the visual field of operation was satisfactory.Blood pressure of the patient returned normal 6 months postoperatively.And there was no indication of tumour relapse or matastasis.Conclusion The modified abdomen pathway can expose the satisfactory visual field,and is safe and effective for adrenal gland tumor operation.

OBJECTIVETo study the overexpression of Sox9 gene on rabbit bone marrow mesenchymal stem cells for repairing articular cartilage injury in vivo.

METHODSRabbit bone marrow mesenchymal stem cells (BMSCs) were transduced with lentivirus vector containing Sox9 gene and then cartilage specific molecule was detected by RT-PCR in vitro. Total 48 knee joints of 24 mature New Zealand white rabbits were randomly divided into 3 groups according to different defect treatment. After animals anesthesia,a full-thickness cylindrical cartilage defect of 4 mm diameter and 3 mm deep was created in the patellar groove using a stainlesssteel punch. Meanwhile, the transfected cells were implanted to repair the rabbit model with full-thickness cartilage defects. Cartilage defects tissue was observed with light microscope, electron microscope, HE and immunohistochemistry staining to assess the repair of defects by the complex at 6 weeks or 12 weeks after the implantation.

RESULTSAt 3 days after the transfection, Sox9 gene expression was highest and Sox9 gene expression decreased with the increase of time. At 3 days after the transfection, the expression of collagen type II began and reached the peak at 14 days. It showed that the bone marrow mesenchymal stem cells went into chondrogenic differentiation after transfected by Sox9 gene. Histological observation showed that at 6 weeks after the operation, the defects in the experimental group was filled with hyaline like cartilage tissue, 12 weeks after operation,the defects of cartilage and subchondral bone had satisfactory healing. Both at 6 and 12 weeks postoperatively, the defects were filled with fibrous tissues in control groups. Meanwhile, immunohistochemical staining of sections with type II collagen antibodies showed the proteins in the regenerated tissue stained positive for type II collagen and stronger than the control groups. The histological scoring system indicated that the cartilage repair of experiment groups were better than the two control groups with statistical significances.

CONCLUSIONOverexpression of Sox9 gene on rabbit bone marrow mesenchymal stem cells (BMSCs) promote the repair of cartilage defect.

This article tried to discuss that spleen deficiency is the key mechanism of hepatitis B virus associated glomerulonephritis from TCM and Western medicine viewpoint. From the view of pathophysiology, energy metabolic disorder caused by mitochondrial injury and its series of damages are similar to symptoms caused by spleen deficiency appeared as yin fire and organs dystrophy, so mitochondrial injure belongs to spleen deficiency. And mitochondrial damage can further aggravate the virus replication of hepatitis B virus associated glomerulonephritis, causing damage to the kidney. Therefore, from the view of Western medicine, it can be known that spleen deficiency determines whether the liver function damage in the process of hepatitis B virus associated glomerulonephritis and lower energizer transformation. In terms of TCM, spleen deficiency plays an important role in all stages of the disease, and determines the outcome and prognosis of the disease. Therefore, this article proposed that the spleen deficiency is the mechanism of hepatitis B virus associated glomerulonephritis, which can provide references for clinic.
