Objective To evaluate the relationship between children interleukin-1 receptor antagonist gene(IL-1RN) polymorphisms and susceptibility to febrile seizures(FS).Methods Matching case-control study was carried out,blood samples from 52 patients with FS and 53 healthy children were collected.Genomic DNA was extracted and examined by polymerase chain reaction(PCR) amplification for judging IL-1RN genetype.Results Only Ⅰ/Ⅰ,Ⅰ/Ⅱ,Ⅱ/Ⅳ genetypes of IL-1RN were found in the surveyed Chinese population of Han nationality in Guangdong Province.No significant differences of these genotypes were observed in patients and controls.But the allele frequencise of Ⅰ,Ⅱand Ⅳ in patients were 95.2%,3.8% and 1.0%,respectively,while these frequencise in controls were 84.9%,10.4% and 4.7%,respectively.The allele frequency of IL-1RNⅠin patients was obviously higher than that in controls(P

In order to improve the metabolism yield of cordycepin and adenosine,we studied nitrogen sources ,the levels of nitrogen sources and carbon sources,dynamic development in liquid culture ,as well as the total yield of cordycepin and adenosine in culture system through determining the contents of cordycepin and adenosine by HPLC .The results are as follows: not only animal protein but also some plant protein is very good nitrogen sources; in culture solution the suitable levels of nitrogen sources and carbon sources is respectively 3% and 4%; the content of adenosine in culture solution is very low, while it is quite high in mycelia; it is much higher that the total yield of cordycepin in culture solution than in mycelia; when the culture system is oscillated and cultured after 7~9 days, the total yield of cordycepin and adenosine are both high.

Objective To explore the effect of ACE-inhibitor perindopril on the expression of scavenger receptor A (SR-A) gene in the kidney of diabetic rats.Methods Diabetes were induced in male Sprague-Dawley rats by peritoneal injection with streptozotocin (60mg/kg).The rats were then random di vided into normal control group, diabetes group and ACEI treatment group [4mg/(kg·d) for 24 weeks].Blood glucose concentration and 24h urinary albumin excretion were determined.The renal morphological change was observed.Immunohistochemistry was used to analyze CD68 positive macrophages,and the Mrna of SR-A in renal tissue was detected by quantitative real-time PCR.Results Compared with normal control group,blood glucose concentration,24h urinary albumin excretion and the number of CD68 positive macrophages were significantly increased [(5.3 ± 0.6) mmol/L vs (26.7 ± 3.3) mmol/L;(2.7 ± 1.3) mg/24h vs (26.7 ± 1.8)mg/24h;(0.77 ±0.24)/gcs vs (2.55 ±0.46)/gcs;(6.13 ±0.50)/HPF vs (11.9 ±2.12)/HPF;P ＜0.05],and the expression of SR-A Mrna were significantly up-regulated in diabetes group [ (5.6 ± 1.2 vs 1.5 ±0.2),P ＜0.05].After intervention with ACE-inhibitor,the up-regulations of the above mentioned parameters,except blood glucose concentration,were all significantly inhibited [ (3.6 ±1.4)mg/24h;(1.03±0.37)/gcs;(8.28±1.19)/HPF;3.4±0.7;P ＜0.05].Conclusion ACE-inhibitor might have renoprotective effects of diabetic nephropathy,it probably was associated with inhibiting the expression of SR-A gene.

OBJECTIVETo investigate the liver injury in model rats with endotoxemia and to observe the protective effect of Compound 912 Liquid on it.

METHODSRats were randomly divided into three groups, the endotoxemia model group (EMG, injected by lipoplysaccharides (LPS) peritoneally), the intervention group (IG, treated with Compound 912 Liquid via gastrogavage 1 h before model establishing) and the normal control group (NCG). Blood samples of rats were taken at the time points of the 2nd, 4th, 8th, 12th, 48th, 72nd hour and the 7th day after modeling for measuring liver function, levels of plasmatic endotoxin, tumor necrosis factor alpha (TNF-alpha), interleukin-10 (IL-10). The pathological change of liver was observed using light microscope and electro-transmission microscope.

RESULTSThe peak concentration of endotoxin detected at 2 hour after modeling in the IG was significantly lower than that in the EMG (0.358 +/- 0.056 vs 0.685 +/- 0.030), but insignificant difference (P > 0.05) was shown between them in TNF-alpha level. The level of IL-10 continuously rose in IG after treatment, it was still higher than normal level until day 7 (49.096 +/- 4.076 vs 43.454 +/- 5.928, P < 0.05).

CONCLUSIONLPS can induce the increase of serum inflammatory cytokines and anti-inflammatory cytokines in rats to injure liver. Therefore, the inflammatory reaction indicated by LPS may be one of the mechanisms for liver injury. Preventive medication with Compound 912 Liquid showed a significant liver protective effect.

OBJECTIVETo investigate the relative contribution of lifestyle and obesity to the risk of developing type 2 diabetes.

METHODSAll baseline survey data were based on the program Prevention of Multiple Metabolic Disorders and Metabolic Syndrome in Jiangsu Province (PMMJS) which was conducted during April 1999 to May 2004. In the baseline survey, 8685 participants were selected using multi-stage sampling method. Frem March 2006 to November 2007, 4582 participants who had been in the study for at least 5 years were included in the follow-up survey. A total of 3847 participants were followed and of them 3461 non-diabetic subjects were included in this analysis. High fat diet or not, low fiber diet or not, sedentary or not and occupational physical activity classification were defined as lifestyle variables and the incidence of type 2 diabetes at follow-up survey was defined as outcome variable. It was prospectively examined that the separate and joint association of lifestyle and obesity with the development of type 2 diabetes in subjects recruited from PMMJS, using logistic regression model.

RESULTSA total of 162 incident cases of type 2 diabetes during 6.3 years of follow-up in total 3461 participants were documented. The incidence rate was 4.7%. After adjusted for sex, age, family history of diabetes, blood pressure, lipids and fast plasma glucose, risk of type 2 diabetes increased with lighter occupational physical activity (compared with vigorous group, moderate group aRR = 2.15, 95%CI: 1.26 - 3.68; light group aRR = 2.39, 95%CI: 1.12 - 4.87), sedentary lifestyle (aRR = 2.94, 95%CI: 1.90 - 4.54), low fiber diet (aRR = 1.58, 95%CI: 1.01 - 2.53), overweight (aRR = 1.33, 95%CI: 1.01 - 1.90) and obesity (aRR = 1.59, 95%CI: 1.07 - 3.75). In joint analysis of lifestyle and obesity, the impact of sedentary lifestyle (in BMI < 25 group, aRR = 3.42, 95%CI: 1.99 - 5.86; in BMI ≥ 25 group, aRR = 2.41, 95%CI: 1.13 - 5.12) and low fiber diet (in BMI < 25 group, aRR = 1.42, 95%CI: 0.81 - 2.54; in BMI ≥ 25 group, aRR = 2.63, 95%CI: 1.15 - 6.03) on diabetes were independent of overweight and obesity. When stratified by sedentary lifestyle or low fiber diet, there was no association between overweight/obesity and diabetes risk (sedentary aRR = 2.04, 95%CI 0.87 - 4.71, non sedentary aRR = 1.21, 95%CI: 0.82 - 1.78; non low fiber diet aRR = 1.26, 95%CI: 0.87 - 1.84, low fiber diet aRR = 1.88, 95%CI: 0.80 - 4.80).

CONCLUSIONUnhealthy lifestyle, overweight and obesity independently increase the risk of type 2 diabetes. The magnitude of risk contributed by sedentary lifestyle and low fiber diet are much greater than that imparted by overweight and obesity.
