Objective To investigate the differences in visceral fat area measured by bioelectrical impedance analysis in different sex and age groups, and explore the relationship between visceral fat area and other metabolic risk factors. Methods This study enrolled 72 in-patients in the department of cardiology in Peking University First Hospital between August, 2014 and October, 2014. The visceral fat area and the subcutaneous fat area were measured by DUALSCAN HDS-2000 in all patients. Results were compared between different sex and age groups and the relationship between visceral fat area and metabolic risk factors were analyzed. Resu1ts Male had larger visceral fat area than female [ ( 114. 04 ± 38. 27 ) cm2 vs. (92. 09 ±30. 57)cm2, P=0. 019], while female had larger subcutaneous fat areas than male [(223. 92 ± 73. 58)cm2 vs. (270. 35 ± 82. 13) cm2, P =0. 019] . Subcutaneous fat area and visceral fat area were positively correlated in both male ( r=0. 777, P﹤0. 001) and female ( r=0. 601, P=0. 002). There were no significant differences in visceral fat area among different age groups (P=0. 582). And visceral fat area had a positive correlation with body mass index (r=0. 748, P﹤0. 001), waist-hip ratio (r=0. 577, P﹤0. 001), abdominal circumference (r =0. 752, P ﹤0. 001) and HbA1c levels (r =0. 413, P =0. 001). Conc1usions There are sex differences in visceral fat area and subcutaneous fat area. The visceral fat area max be related to blood glucose levels and presence of diabetes.

Objective To analyze the relationship between the genetic polymorphisms of uridinediphosphate glucuronosyltransferase 1A9 (UGT1A9) and mycophenolic acid (MPA)pharmacokinetics in Chinese kidney recipients.Methods Gene mutations (C-440T/T-331C,C-2152T,T-275A,T98C) were detected in 196 recipients by PCR-LDR.On the 28th day after transplantation,the plasma samples which were obtained at the time points of predose,0.5 h and 2 h after administration were measured by an immunoassay method (Emit Mycophenolic Acid Assay,Dade Behring).MPA-AUC0-12 was calculated based on these three data.Correlation between single nucleotide polymorphisms (SNPs) and MPA pharmacokinetics was analyzed.Results C-2152T,T-275A and T98C genotypes of UGT1A9 were not found in 196 recipients.The frequency of C-440T/T-331C gene mutation was 14.29% (28/196).The mean value of MPA-AUC0-12 was 40.6±11.8 wild genotype,respectively (P＞0.05).Conclusion C-2152T,T-275A and T98C genotypes of UGT1A9 are scarce in Chinese kidney recipients.In this study,there is no distinct relationship between -440/-331 SNPs and MPA pharmacokinetics in Chinese allograft recipients.

AIM To explore the role of nitric oxide (NO) mediators in seizure behavior and the related expression of interlukin 6(IL 6). METHODS The IL 6 immunoreactivity (IL 6 ir) and behaviour were observed in kainic acid (KA) induced seizure following pretreatment with L nitroarginine( L NNA), a inhibitor of nitric oxide synthase(NOS), or the same number of moles of L arginine( L Arg). RESULTS The results showed that time dependent seizures were induced on animals after administration of KA (10 mg?kg -1 ), accompanied by the immediate enhancement of IL 6 ir in hippocampal structure, piriform area and cortex. The behaviors of rats were not markedly altered by chronic pretreatment with L NNA (50 mg?kg -1 ) or L Arg (40 mg?kg -1 ). However, after the administration of KA, the seizure behaviors were obviously different in the group of L NNA and L Arg respectively. Seizure was agrevated in the animals with L NNA pretreatment and many rats died at KA 3 hours, whereas seizure was alleviated after KA in the group of L Arg. IL 6 expression was apparently up regulated in some brain areas such as hippocampus in the group of KA pretreated with L NNA, but opposite effects appeared in the group pretreated with L Arg before KA injection. CONCLUSION These results indicate that endogenous NO mediators may alleviate the seizure behaviors and may down regulated the early expression of IL 6 in KA challenged seizure, but it the mechanism of the early expression of IL 6 with the homeostasis of endogenous NO mediator merits further study.nismoftheearlyexpressionofIL 6withthehome

Objective To investigate the clinical features and prognosis of pulmonary infection at different stages after renal transplantation.Methods Medical records of 61 patients with pulmonary infection after renal transplantation from January 2003 to July 2008 in our hospital were reviewed in this retrospective study. According to stages of infection onset, we divided all patients into two groups, early onset group (43/61, 70.5%, ≤12 months after transplantation) and late onset group (18/61, 29.5%, >12 months after transplantation). Clinical manifestations and prognosis were compared between the two groups.Results In the early onset group, the radiographic manifestation suggested diffuse interstitial changes of bilateral lungs. Combination of anti-infective therapy and early mechanical ventilation was preferred. While in the late onset group, unilateral pulmonary lesions were seen in most cases. More patients showed cardiac and gastrointestinal complications in this group, the mortality of which was much higher. Conclusions Pulmonary infection is a major complication of renal transplantation. The etiology, clinical characteristics and prognosis of infection varies with the stage after transplantation. Effective preventive and therapeutic measures should be applied more vigorously in patients with pulmonary infection, especially early onset ones.

AIM To observe the expression of inducible nitric ox ide synthase (iNOS) in the rats' hippocampus of kainic acid (KA) induced-seizur es and the effect of L-arginine(L-Arg) or L-nitroarginine(L- NNA) chronic intervention before KA. METHODS The expression of iN OS mRNA by RT-PCR and behaviour were observed after administration of convulsan t dose of KA (10 mg?kg -1 ) and pretreatment with NO predecessor (L-Ar g, 40 mg?kg -1 ) or a inhibitor of NOS(L-NNA, 50 mg?kg -1 ) befo re KA. RESULTS The time-dependent seizures were induced on rats after giving KA, and were improved and serious in the animals with L-NNA pr etreatment, but they were alleviated by L-Arg pretreatment before KA. Compa red with control, iNOS mRNA expression was feebly at KA 3 h, continuative improv ement accompanying KA time prolonged, and it was markedly enhanced at KA 24 h. I t couldn't be examined at KA 2 d or 3 d, and was obviously improved at KA 7 d a gain. iNOS mRNA appeared weak in the rats hippocampus with L-Arg pretreatme nt after KA 1 h, whereas it wasn't found in L-NNA pretreatment animals. CONCLUSION iNOS mRNA expression appeared in the hippocampus of seizu re rats at a few time after KA, and L-Arg chronic intervention before KA ha s a little effect on it.

Objective To investigate the effect of cyclosporine blood level at first year after kidney transplantation on patients with a survival time over 10 years. Methods 380 patients with functional allograft, a survival time over 10 years and long-term administration of cyclosporine A (CsA) were studied, and received CsA-based treatments. According to the blood CsA level at the first year after kidney transplantation, patients were divided into five groups: group 1, blood CsA level was above 0. 208 μmol/L (1 μmol/L = 1201.9 μg/L), group 2, blood CsA level between 0. 166-0. 208μmol/L; group 3, blood CsA blood level between 0. 125-0. 166 μmol/L; group 4, blood CsA blood level between 0. 083-0. 125 μmol/L; group 5, blood CsA level less than 0. 083 μmol/L. Systolic blood pressure (SBP), diastolic blood pressure (DBP), serum creatinine(SCr), uric acid (UA), cholesterol (CH), triglyceride (TG), alanine aminotransferase (ALT), direct bilirubin (DBil) and total bilibubin (TBil), albumin (Alb), hemoglobin (Hb), count of white blood cells and positive rate of proteinuria in 5 groups at the 1st, 5th and 10th year after kidney transplantation were analyzed. Results At the 5th year SBP in groups 1 and 2 was higher than in groups 3, 4 and 5. UA level in group 5 was lower than other groups, and Alb level in group 5 was higher than other 4 groups. Proteinuria positive rate in groups 4 and group was lower than other groups. At the 10th year after kidney transplantation,indexes among 5 groups had no statistically significant difference, except for SBP, DBP, DBil and CH in some groups. There was also no significant difference in SCr level among 5 groups at the 5th or 10th year after transplantation. Conclusion Blood CsA levels at the first year after kidney transplantation has no significant effect on long-term allograft function. But higher level of CsA (＞0. 166μmol/L) at the first year maybe predict high rate of hypertension, high blood UA and proteinuria at the 5th and 10th year after transplantation.
