Objective: Our purpose was to study the effect of anisodamine on the injury of myocardium after myocardial ischemia reperfusion. Methods: Eighteen patients (ASA grade Ⅱto Ⅲ) scheduled for valve replacement, were randomly divided into 2 groups during extracorporeal circulation. Anisodamine (0.25 mg/kg) was given intravenously in the anisodamine group before reperfusion. Equivalent volumes of normal saline were administered in the control group. The central venous blood samples were collected at different time after ischemia and reperfusion. We then measured the concentrations of lactic dehydrogenase (LDH), creatine kinase (CK), and malondiadehyde (MDA) with biochemical methods. Results: The levels of serum LDH, CK, and plasma MDA increased significantly in the control group during ischemia and reperfusion. In the anisodamine group, the levels of serum LDH and CK increased. But the values were lower at corresponding time than those in the control group (P<0.05) during reperfusion. The plasma level of MDA unchanged in the anisodamine group during ischemia and reperfusion. The postoperative cardiac function recovered much more better in the anisodamine group. Conclusion: Anisodamine can reduce the degree of reperfusion injury. A certain protective effect on myocardial ischemia reperfusion injury exsists during valve replacement.

Objective A prospective randomized controlled trial was carried out to explore the best time of In-domethacin suppositories administration for the prevention of post-ERCP pancreatitis in high-risk groups. Methods 81 patients were enrolled in the study finally. Patients were randomized into group A (100 mg rectal Indomethacin suppositories was administrated immediately after ERCP), group B (100 mg rectal Indomethacin suppositories was administrated half an hour after ERCP) and group C (ERCP alone group, which did not give Indomethacin supposito-ries). The level of serum amylase, urine amylase, serum CRP, serum IL-6, serum TNF-α were measured before, 3 h, 24 h and 48 h after ERCP, and the incidence of PEP and hyperamylasemia were analyzed. Results There was 1 case (4.00%) of PEP in group A, 2 cases (5.41%) of PEP in group B and 5 cases (26.31%) of PEP in group C;the incidences of PEP of group A and group B were significant lower than that in group C (P < 0.05). There was 1 case (4.00%) of hyperamylasemia in group A, 5 cases (13.51 %) of hyperamylasemia in group B and 6 cases (31.6 %) of hyperamylasemia in group C, and the incidences of hyperamylasemia of group A and group B were significant lower than that in group C ( P< 0.05). Conclusion Administration of 100 mg Indomethacin suppositories immediately or half an hour after ERCP can effectively reduce the incidence of PEP and hyperamylasemia.

OBJECTIVE:To observe the clinical efficacy of sitagliptin combined with benazepril in the treatment of diabetic nephropathy(DN). METHODS:Sixty DN patients admitted to our hospital during Sept. 2014-Jun. 2015 were divided into sitagliptin group,benazepril group,drug combination group according to random number table,with 20 cases in each group. Based on routine treatment,sitagliptin group was given sitagliptin 100 mg orally,qd;benazepril group was given Benazepril 10 mg orally,qd;drug combination group was given sitagliptin 100 mg+benazepril 10 mg orally,qd. The drug dosage would be doubled if the blood pressure of patients in 3 groups had not yet reached the standard. Treatment course of 3 groups lasted for 12 weeks. The levels of 24 h urine protein,IL-6 and Cys-C were measured in 3 groups before and after treatment. Clinical efficacies and the occurrence of ADR were observed. RESULTS:Total response rate of drug combination group(90.00%)was significantly higher than those of sitagliptin group (65.00%)and benazepril group(70.00%);there was statistically significance(P<0.05). After treatment,the levels of 24 h urine protein,IL-6 and Cys-C in 3 groups were significantly lowered,compared to before treatment;those of drug combination group was significantly lower than those of other 2 groups;there was statistically significance(P<0.05). There was no statistical significance in above indexes between sitagliptin group and benazepril group(P>0.05). No obvious ADR was found in 3 groups during treatment. CONCLUSIONS:Both sitagliptin and benazepril can decrease the levels of 24 h urine protein,IL-6 and Cys-C,while drug combination shows better effect and clinical response rate,and does not influence the safety of drug use.

Objective To investigate the relationship between serum ferritin and p-cell function,insulin resistance in elderly patients(age>60 years)with type 2 diabetes and impaired glucose tolerance.Methods Total 1143 patients with type 2 diabetes,448 patients with impaired glucose tolerance(IGT),and 2 950 subjects with normal glucose tolerance(NGT)were recruited for the measurments of height,weight,serum triglyceride(TG),total cholesterol,fasting plasma glucose(FPG),fasting insulin(FINS),postprandial 2 h plasma glucose(2hPG),and serum ferritin.Homeostasis model assessment of insulin resistance(HOMA-IR)and QUICK index were used to estimate insulin resistance,and homeostasis model assessment of β cell function(HOMA-p)and disposition index(DI)to evaluate p-cell function.Results The results showed that the level of serum ferritin was significantly higher in type2 diabetes mellitus group than NGT group(P<0.01).HOMA-IR was gradually increased,and HOMA-β,QUICK,and DI decreased from NGT to IGT,type 2 diabetes mellitus groups(all P < 0.05).Spearman and partial correlation analysis showed that partial adjustment for age and sex,serum ferritin was positively associated with FPG,2hPG,TG,FINS,and HOMA-IR,and negatively associated with HOMA-β,QUICK,and DI.Stepwise regression showed that serum ferritin was associated with QUICK,BMI,and TG.Conclusion The results suggest that iron overload exists in elderly patients with type 2 diabetes.With increasing serum ferritin level,insulin resistance increases and p-cell function decreases in the elderly patients with abnormal glucose metabolism.

Objective To investigate the adiponectin levels in non-obese first-degree relatives (FDR)of type 2 diabetic subjects and its relation to insulin sensitivity and the intima-media thickness of the common carotid artery (IMT) during 5-year follow-up. Methods Fifty-three FDR subjects and 37 control subjects who were free of type 2 diabetes were enrolled. Plasma adipenectin, lipid profile, blood glucose, fasting insulin, and blood pressure were determined at baseline and after 5-year follow-up. IMT and endothelial-dependent vasodilation (EDVD) were measured by high-resolution B-mode ultrasound imaging. Homeostasis model assessment was used to evaluate insulin resistance (HOMA-IR)and β-cell function (HOMA-β). 29 FDR subjects and 20 control subjects completed the follow-up. Results Comparing with the control, plasma adiponectin levels in non-obese FDR subjects were lower at baseline [(10.06±5.79)vs (14.43±7.91) mg/L, P< 0.05]. Plasma adiponectin were decreased 24.0% in non-obese FDR and 36.7% in control duning 5 year follow-up (both P<0.05). Adiponectin levels were negatively correlated with waist-to-hip ratio (r = -0. 397), fasting blood glucose (r = -0. 373), IMT (r = -0. 372), and HOMA-IR (r=-0. 40)in the non-obese FDR. After adjusting other relevant risk factors,adiponectin was associated with age, high-density lipoprotein-cholesterol, and IMT in multiple regression analyses in non-obese FDR group. In the control group, a similar analysis revealed that low-density lipoprotein-cholesterol and IMT explained 25% of the variability in the adiponectin concentration. Conclusion Plasma adiponectin levels were decreased after 5 years in both non-obese FDR and control subjects. Decreased adiponectin level may be related to IMT increment.

Objective To investigate the clinical value of transient elastography in adult after liver transplantation,by means of evaluating the correlation of liver stiffness measured by FibroScan with liver/renal functions.Method Forty-three patients received orthotopic liver transplant in our hospital during Dec.10,2013 and Mar.19,2014 were included in this study.Liver stiffness measurement (LSM) was performed after transplantation.Clinical data and laboratory tests including liver function and renal function were collected and analyzed.Result Bivariate correlation showed that body mass index (BMI),MELD score,graft-to-recipient weight ratio (GRWR) and warm ischemia time had no correlation with LSM.LSM at the 1st day after transplantation (LSM-1) showed no correlation with cold ischemia time,but LSM at the 7th day after transplantation (LSM-7) did,with R =0.335,P =0.028.LSM-1 showed positive correlation with the ICU time (R =0.488,P =0.001),but LSM-7 didn't.There was significantly positive correlation between LSM and aspartate aminotransferase,bile acid and creatinine,but no significant correlations were found between LSM and alanine arninotransferase,alkaline phosphatase,cholinesterase,gamma-glutamyl transferase,total bilirubin,direct bilirubin,indirect bilirubin,urea nitrogen and uric acid.The group with higher LSM-1 had longer ICU time than the lower group (9 d vs,7 d,P =0.013),and so was the hospital stay (34 d vs.23 d,P =0.023).For the LSM-7,there was no significant difference in ICU time and hospital stay between the two groups.The group with higher LSM-1 had higher serious complication incidence than the lower group (78.57％ vs.27.59％,P =0.002),but the two groups in LSM-7 showed no significant difference in serious complication incidence.Conclusion The LSM partially correlates with the liver function and renal function of liver transplantation recipient,and may have its clinical value for assessing the early prognosis after liver transplantation.

Objective To observe the role of rosiglitazone in unclipped kidneys of two-kidney- one-clip hypertensive rats and examine its relationship to angiotensinⅡreceptors.Methods Two- kidney-one-clip hypertensive rats were divided randomly into 4 groups as follows:positive control group (CONT),traditional antihypertensive drugs group (TAHD,reserpine 50?g?kg~(-1)?d~(-1), dihydralazine 6.25 mg?kg~(-1)?d~(-1) and hydrochlorothiazide 6.25 mg?kg~(-1)?d~(-1),regular-dose rosiglitazone group (RRGL,rosiglitazone 5 mg?kg~(-1)?d~(-1)),and high-dose rosiglitazone group (HRGL, rosiglitazone 20 mg?kg~(-1)?d~(-1)).Sham operation rats were as negative controls.Each group had 8 rats. Animals were monitored and sacrificed at 10th week.Results Blood systolic pressure in TAHD group and HRGL group was significantly lower than that in CONT group [TAHD(137?27 ) mm Hg and HRGL (143?16) mm Hg vs CONT (191?25 ) mm Hg,P＜0.05],but no significant difference between the former two groups was found.Nor did the blood systolic pressure between RRGL group [(176?18) mm Hg] and CONT group.At 10th week,rats in SHAM group and treated groups had lower urinary urinary protein excretion rate,glomerular injury score and wall-to-lumen ratio of arteriole than those in CONT group [vs CONT urinary protein excretion rate (44.60?17.40) mg/24 h,P＜0.05; vs CONT glomerular injury score 60.85?33.05,P＜0.05;vs CONT wall-to-lumen ratio of arteriole 2.33?1.01,P＜0.01,except TAHD group].Though with the similar level of blood pressure,blood glucose and lipid,HRGL,compared with TAHD group showed lower urinary protein excretion rate [HRGL (16.78?3.50) mg/24 h vs TAHD (27.94?12.79) mg/24 h,P＜0.05],decreased glomerular injury score (HRGL 18.04?7.76 vs TAHD 27.92?6.39,P＜0.05) and wall-to-lumen ratio of arteriole (HRGL 1.75?0.38 vs TAHD 2.16?0.90,P＜0.05) in the cortexes of unclipped right kidneys.The expression of type 1 angiotensinⅡreceptor (AT1R) mRNA was no difference in HRGL group and TAHD group,but the expression of type 2 angiotensinⅡreceptor (AT2R) mRNA was more intensive in HRGL group.Conclusion Rosiglitazone can protect the kidneys from hypertensive injury,especially in high dose.The beneficial effects seem incompletely dependent on the metabolism modulating and reduction of blood pressure,but in relationship to the upregulation of AT2R mRNA.
