Effects of Allicin on myocardial fibrosis and TLR4/NF-κB pathway / 中国免疫学杂志

Objective:To observe the effect of Allicin in cardial fibroblasts (CFs) proliferation and Collagen secretion,and to explore its role on TLR4/NF-κB signal pathway.Methods:CFs of neonatal Wistar rats were isolated and cultured ,then was stimulated with AngⅡ.CFs proliferation was measured by thiazolyl blue ( MTT) assay.The expression of collagenⅠ,collagenⅢ was measured by ELISA.mRNA expression of TLR4 and NF-κB were detected by reverse transcription-polymerase chain reaction ,protein expression of TLR4 and NF-κB were detected with Western blot.Results: Allicin could reduced MTT value of cardial fibroblasts ( P<0.01 ) , and inhibited expression of collagenⅠ,collagenⅢ(P<0.01),which in a dose-dependent manner.Allicin could reduced mRNA expression of TLR4 and NF-κB and protein expression of TLR 4 and NF-κB in CF induced by Ang Ⅱ ( all P<0.01 ) .Conclusion: Allicin can inhibit Myocardial fibrosis ,which mechanism is possible by inhibiting TLR 4/NF-κB signal pathway.

Relationship between the prevalence of hypertension and metabolic syndrome in minority populations of Baise, Guangxi province / 中华内分泌代谢杂志

There were 3 000 Zhuangs,1 102 Miaos, and 1 283 Yaos in Baise City of Guangxi,who were enrolled in this population sampling stratfying survey. Height, weight, blood pressure, fasting blood glucose, and lipids were determined, and compared with those of 2 000 Hans of the same town. The prevalence of hypertension and metablic syndrome in Zhuang inhabitants was high, so were the disorders of glycemia and lipidemia, while in Miao and Yao minorities, the prevalences were comparatively lower. The awareness, treatment, and control of hypertension in these minorities were insufficient.

Study on the relevance between hypertension and serum uric acid in residents in Baise City of Guang-xi / 中华风湿病学杂志

ObjectiveTo realize the relevance between hypertension and serum uric acid (SUA) in residents in Baise City.MethodsTwenty one thousand,five hundred and eighty eight Baise residents were examined.The body weight,height,waist circumference,hip circumference,blood pressure(BP) were recorded and blood lipidlevels,blood glucoseand serum uric acid (SUA) were tested.The relevance between hypertension and hyperuricemia (HUA) was analyzed by multi-factor variance analysis,x2 test,t test,linear regression and Logistic regression analysis.ResultsHypertension prevalence rate was 31.5％,the frequency of HUA was 12.0％,and 5.8％ residents had both.For patients with both hypertension and HUA,when compared to those with normal serum uric level,their mean diastolic blood pressure(DBP) was(84±10),(72±6) mm Hg res-pectively,there mean systolic blood pressure (SBP) was(151±12),(127±6) mm Hg respectively,and pulse pressure (PP) was (50±12),(37±8) mm Hg respectively.The average BMI of those two groups was (23.9±2.6),(21.7±2.4) kg/m2 respectively.The average TC level was (6.0±1.3),(5.2±1.1)mmol/L respectively,the average TG level was(2.3±2.2),(1.5±0.7) mmol/L respectively,and the average LDL-C level was(3.4±1.3),(3.0±1.1) mmol/L respectively.All these parameters were higher than those people without hypertension or HUA(P＜0.01).However,the situation of HDL-C[ (1.2±0.4),(1.5±0.5)mmol/L] was the opposite (P＜0.01).Regression analysis had shown that age,BMI,waist-hip ratio,SUA,blood glucose,TC,TG,HDL-C and LDL-C were independent risk factors for hypertension,while people with HUA was 3.1 times more when compared to those without HUA.The prevalence rate of HUA in people with hypertension was 2.6 times higher than that of the control group.ConclusionHypertension and HUA are two public health problems that prevalent in the residents in Baise City.Obesity,high blood glucose level and hyperlipidemia are thebasis for the development of hypertension and HUA.Hypertension can be the cause of HUA and verse versa.They may have mutual interactions.The adverse effect of HUA on-cardiovascular system should be taken into consideration clinically.
