30,BMI≥25 kg?m -2 ),who were admitted to the hospital from Apr.2004 to Sep.2005,were induded in the study.They underwent CPAP.The PSG and leptin,ghrelin,true insulin,fasting blood glucose are measured before the treatment,and one week and six months after the treatment.Results After one week,there was a little decrease of leptin and ghrelin,and no change in true insulin and fasting blood glucose.After six months,only 16 patients improved a lot in AHI and hypoxemia.There was significant decrase of leptin and ghrelin and also a change of true insulin.Conclusion These data indicate that the elevated leptin and ghrelin levels are not determined by obesity alone,since they decrease during CPAP therapy.The glucose metabolic disturbance and insulin resistance in OSAS are improved after 6 months of CPAP therapy.Therefore,we can think that OSAS patients have metabolic disturbance of leptin and ghrelin,which is one of factors of obesity.

Methods Seventy-two hours after bilateral ureteral ligation,12 uremic dogs were hemodialyzed for 2 hours,yeilding decreases in plasma urea from (66. 76?13.70) mmol/L to (17. 85?5. 84)mmol/L( P

Atherosclerosis is a pathegenesis process involved in the inflammatory and proliferative responses of cells in which endothelial cells have an important function in the regulation of a variety of genes. A variety of molecules have been identified in the atherosclerotic environment that are able to activate NF ?B. Possible functional implications for activated NF ?B in atherogenesis are discussed by protecting endothelial cells selectively, perhaps, it may provide a new method for the therapy of the atherosclerosis.

ObjectiveTo investigate the clinical significance and histological origin of glomerular epithelial proliferative lesion in patients with focal segmental glomerulosclerosis (FSGS). MethodsSeventy-four patients with idiopathic FSGS hospitalized in Peking University First Hospital from Jan. 2000 to Dec.2005 were enrolled in this study. Patients were classified into two groups according to with or without glomerular epithelial proliferative lesion. Estimation of active and chronic pathological scores was carried out using a semi-quantitative grade system by two pathologists. Clinical and pathological characteristics were compared between two groups. Immunohistochemical studies were performed to analyze the histological origin of glomerular epithelial proliferative lesion. ResultsThirty-one patients with glomerular epithelial proliferative lesion showed shorter interval from presentation to biopsy (P<0.05), higher percentage of nephrotic syndrome (NS) (P<0.05), higher frequency of segmental glomerulosclerosis(P<0.05), higher pathological active scores (P<0.05) and lower pathological chronic scores (P<0.05)as compared to 43 patients without glomerular epithelial proliferative lesion. Twenty-nine patients were followed up and renal survival rate in patients with glomerular epithelial proliferative lesion (39.7%) was significantly lower than that in patients without glomerular epithelial proliferative lesion (83.3%) (P=0.049). The frequency of glomerular epithelial proliferative lesion and the serum creatinine (Scr) level at biopsy were independent predictors of ESRD (OR value was 1.204, 1.008 respectively ). Glomerular epithelial proliferative lesion did not express mature podocyte markers including WT-1 and pedocalyxin, but stained positive for PCNA, PAX-2 and CK-8. ConclusionsGlomerular epithelial proliferative lesion represents the pathological change of acute stage and active lesion of FSGS, and also may be the pathological marker of severe clinical presentation and worse renal survival. Glomerular epithelial proliferative lesion may be derived from proliferation of parietal epithelial proliferation or de-differentiated podocytes.

Extended liver resection may provide longterm survival in selected patients with hilar cholangiocarcinoma.In May 2013,a patient with hilar cholangiocarcinoma received right hemihepatectomy combined with caudate lobectomy under the guidance of precision hepatectomy technique.The porta hepatis was clamped in the operation for 3 times intermittently.The operation time was 8 hours,and the volume of intraoperative blood loss was 600 mL.The patient was discharged at postoperative day 14.The results of pathological examination confirmed that the patient had moderately-highly differentiated adenocarcinoma with full-thickness infiltration of the bile duct and tumorfree margins.No tumor recurrence was detected during the followup which was lasted for 6 months.The operation was carried out based on the three dimensional reconstruction,liver reserve function evaluation,intraoperative controlled low central venous pressure and precision hepatectomy technique,and the results were satisfactory.

OBJECTIVETo analyze the changes of patients with type 2 diabetes in different stages in glucagon (GC) and free fatty acid (FFA) in fasting, OGT and L-Arg experiments, and discusses the role of pancreatic alphabeta cells in diabetes pathogenesis by studying the relations among indexes such as glucagon (GC), free fatty acid (FFA) and blood glucose (BG), insulin, insulin homeostasis model (HOMA) and glucose metabolism hormone secretion curve, in order to provide theoretical basis for the treatment of diabetes.

METHODStudy objects were divided into the T2DM group (45 cases), the IGT group (28 cases) and the NGT group (30 cases) for an OGTT experiment and then an L-Arg experiment on the next day. Under the fasting state, their blood glucose (FBG), insulin (F), glucagon (FGC), free fatty acid (FFA) were detected to calculate HOMA-beta, insulin sensitivity index (ISI) and HOMA-IR of different groups. Meanwhile, efforts were made to calculate different time quantum detected in OGTT and L-Arg experiments and area under the curve AUC(BG), AUC(INS) and AUC(GC).

RESULTObvious overall differences were observed in FFA and FGC of the three groups. FGC of each group was negatively correlated with HOMA-beta and ISI. Among all of the 103 study objects, FGC was positively correlated with FBG and HOMA-IR and negatively correlated with HOMA-beta and ISI, with no correlation with FINS; FFA was positively correlated with FBG, HOMA-IR and negatively correlated with FINS, HOMA-beta, ISI. FGC and FFA were positively correlated in the T2DM group and the IGT group, but with no statistical correlation in the NGT group. The sequence of the three study objects was T2DM > IGR > NGT in AUC(GC) in the OGTT experiment and T2DM > IGR > NGT in in AUC(GC) in the L-Arg experiment, with the significant positive correlation between AUC(GC) and AUC(BG) and significant negative correlation with AUC(INS).

CONCLUSIONGlucagon and free fatty acid of T2DM and IGT patients increased, which was positively correlated with blood glucose and HOMA-IR and negatively correlated with INS, HOMA-beta and ISI. The increase in glucagons of T2DM and IGT patients indicated inappropriate secretion of pancreatic alphabeta cells among patients with type 2 diabetes.

Objective To study the effect of lentinan on cisplatin’s inhibition on cervical cancer Hela cell line. Method Cervical cancer Hela cell line were divided into LEN group (only lentinan treatment), CIS group (only Cisplatin treatment), LEC group (Both Lentinan and Cisplatin treatment) and CON group (no Lentinan and Cisplatin treatment) according to their treatment methods. The differences of cell proliferation, cell cycle, PI and apoptosis were compared. Results The differences of absorbance between LEN group and CON group were not significant d1-d8 after treatment, but significant between CIS and LEC group (P<0.05). The absorbance in LEC group was significantly lower than in CIS group (P<0.05). The differences of PI and apoptosis rate in LEC and CIS group were significant (P<0.05), but not between LEN and group. The PI in LEC group was lower than in CIS group (P<0.05), while apoptosis rate was higher (P<0.05). Conclusion Lentinan could significantly promote Cisplatin’s inhibition effects on cervical cancer Hela cell line.
