Objective:To retrospectively analyze the routine clinical laboratory parameters for hepatocellular carcinoma,in an attempt to search for parameters for diagnosis of hepatocellular carcinoma(HCC).Methods:The pre-operation clinical labo- ratory data,such as tumor makers,and serological biochemical indices,hepatitis B virus(HBV)infection markers,and HBV DNA titers,were collected from 828 patients who were pathologically diagnosed as having HCC;then the correlation between these data with tumor size and the pathological grades of HCC was analyzed.Results:It was found that 97.9% of the 828 pa- tients were infected with HBV and 70.9% of them were accompanied by liver fibrosis.We also found that the tumor size was correlated with albumin(ALB),globulin(GLB),A/G,aspartate aminotransferase(AST),ratio of aspartate to alanine amin- otransferase(AST/ALT),gamma-glutamyl transferase(GGT),alkaline phosphatase(ALP),alpha-L-fucosidase(AFU),al- pha-fetoprotein(AFP)and tumor grades;meanwhile,the pathological grades of tumor was correlated to prealbumin(PALB), GGT and tumor size(all P

Objective To explore the risk factors in elderly type 2 diabetes mellitus with cerebral infarction. Methods Retrospective investigarion was performed on 148 elderly hospitalized patients with type 2 diabetes.The patients were classified based on the presence or absence of cerebral infarction and compared with 60 controls.Logis- tic regression analysis was used to reveal the risk factors for cerebral infarction.Results The levels of systolic blood pressure(SBP),body mass index (BMI),fasting blood glucose (FBG),total cholesterol (TC),triglyceride (TG) and plasma fibrinogen(Fg) were higher in the patients with cerebral infarction[141.15?17.46)mmHg,(23.81?3.53)kg/m~2,(8.82?2.81)mmol/L,(5.69?1.15)mmol/L,(2.08?0.75)mmol/L and (4.08?0.65)g/L] than those without cerebral infarction[(129.78?14.65) mmHg,(22.18?3.22)kg/m~2,(7.06?1.72 )mmol/L,(5.09?1.12)mmol/L,(1.62?0.43)mmol/L and (3.48?0.58)g/L].The logistic analysis showed COUR,SBP,FBG, TC,TG and Fg were the independent risk factors for cerebral infarction.Conclusion Early intervention of the inde- pendent risk factors including SBP,FBG,TC,TG and Fg in elderly patients with type 2 diabetes was important for reduction and postponement of cerebral infarction.

Objective To investigate the role of inducible nitric oxide synthase (iNOS) in reduction of myocardial ischemia-reperfusion (I/R) injury by sufentanil preconditioning in rats. Methods Thirty adult male SD rats, weighing 250-330 g, were randomly divided into 5 groups ( n =6 each): sham operation group (group S),I/R group, sufentanil preconditioning group (group SF), sufentanil preconditioning + a specific inhibitor of iNOS S-methyl thiourea (SMT) group (group SF+ SMT) and S-methyl thiourea group (group SMT). In I/R,SF,SF+SMT and SMT groups, myocardial I/R was produced by occlusion of left anterior descending coronary artery for 30 min followed by 120 min reperfusion. Group SF received 30 min infusion of sufentanil 120 μg/kg via caudal vein 24 h before ischemia. Group SF + SMT received infusion of sufentanil 120 μg/kg via caudal vein 24 h before ischemia and then SMT 10 mg/kg was injected 10 min before ischemia. In group SMT, SMT 10 mg/kg was injected 10min before ischemia. MAP and HR were recorded at 30 min before ischemia, at 30 min of ischemia and at the end of reperfusion. The rate-pressure product (RPP) was calculated. Arterial blood samples were obtained immediately at the end of reperfusion to determine the plasma concentration of NO. Then the animals were sacrificed and myo cardial tissues were obtained to determine the area at risk (AAR), infarct size (IS) and iNOS expression. IS/AAR was calculated. Results Compared with group S, MAP and RPP were significantly decreased, while IS/AAR was significantly increased at 120 min of reperfusion in the other four groups, and MAP and RPP were significantly decreased at 30 min of ischemia in I/R and SMT groups ( P ＜ 0.05). Compared with group I/R, no significant change was found in HR, MAP and RPP in SF, SF + SMT and SMT groups, and in IS/AAR and plasma NO concentrations in SF + SMT and SMT groups ( P ＞ 0.05), but IS/AAR was significantly decreased, and the plasma NO concentration and iNOS expression were significantly increased in group SF ( P ＜ 0. 05). Conclusion iNOS is involved in reduction of myocardial I/R injury by sufentanil preconditioning in rats.

Objective To assess the influences of low-protein diet on the renal function and nutritional status in patients with stage 3/4 chronic kidney diseases (CKD).Methods Totally 34 patients with stage 3/4 CKD were randomly divided into group A (protein intake:0.6 g·kg~(-1)·d~(-1);n=14) and B (protein intake:0.8 g·kg~(-1)·d~(-1);n=20).Anthropometric measurement and blood biochemical tests were performed,nutri-tional status was assessed,and 24-hour dietary recall survey was conducted before and after the treatment.Patients were followed up for 6 months.Results In group A,the creatinine level significantly decreased (P=0.010),while albumin level (P=0.042) and the intake of energy (P=0.018) and carbohydrate (P<0.001) signifi-cantly increased after the treatment In all the 34 patients,in group A and group B,the malnutrition rates were de-creased by 14.7%,7.2%,and 21.1% after nutritional intervention.Conclusion The low-protein diet (protein intake 0.6 g·kg~(-1)·d~(-1)),in which part of the staple food was replaced by wheat starch,can increase the in-takes of carbohydrate and energy and improve renal function and nutritional status in patients with stage 3/4 CKD.

LC-Q-TOF-MS and LC-IT-MS in positive and negative ion mode were applied to simultaneously characterize the constituents in Suanzaoren tang. Analysis was performed on an Agilent Zorbax SB-C18, Rapid Resolution HT column(4.6 mmx 50 mm, 1. 8 micro m) with gradient elution of acetonitrile(A) -aqueous solution containing 0. 05% formic acid(B) at a flow rate of 0. 6 mL min(-1) and the column temperature was 30 degreesC. By comparing MS fragmentation, accurate molecular weight, literature date and standard compounds information, a total of48 compounds were successfully identified or speculated. The origins of these compounds were assigned to the corresponding Chinese medicine. Thirty-one compounds were reported in Suanzaoren tang for the first time. LC-Q-TOF-MS combined with LC-IT-MS is a simple and rapid tool for the identification of constituents of Suanzaoren tang, and the results could provide evidence for the research on quality combined and effective constituents of Suanzaoren tang.

The study aims to investigate the embryo-fetus development toxicity of the novel PPAR-δ agonist HS060098 on SD rats. The pregnant rats that were randomly divided into the solvent control group (1% hydroxypropyl methyl cellulose water solution) and HS060098 suspension groups (10, 30 and 100 mg x kg(-1) xd(-1)) were orally administered with HS060098 suspension or vehicle during the gestation of 6 -15 days (GD6-15). At termination (GD20), female rats were sacrificed. The pregnant females were evaluated by corpora lutea count, implantation sites, existence and death of embryos. Fetal sex, weight, externals, variations and malformations of viscus and skeleton were observed. The results show that there were no significant abnormality in maternal general conditions and fetal appearance as well as viscera, but in the 100 mg x kg(-1) x d(-1) group, the maternal weight gain decreased greatly (P < 0.01) and the skeletal ossification delayed remarkably (P < 0.01); in the 30 mg x kg(-1) xd(-1) group, the fatal and litter number of incompletely ossified sternebrae II was higher than those of the control group (P < 0.05); the skeletal malformations occurred in all dose groups, which indicate that the novel PPAR-δ agonist HS060098 had maternal toxicity and adversely effected fetal skeletal development under the experimental conditions.
