Objective To investigate the prevalence of hypertension and its related factors in Hulunbeier Mongolian region. Method A stratified multistage sampling was used to select residents aged 18 and over in a town of Hulunbeier region. 453 persons served as subjects for this questionnaire survey. Their blood pressure, height, weight, waist circumference were measured and body mass index (BMI) were calculated. Then an analysis of the prevalence of hypertension and its related risk factors were performed. Results The hypertension prevalence rate was 34.5%, the standardized rate was 45.4%, and the prevalence in men (48.9%) was significantly higher than that in women (25.4%) (P50 (OR=11.312, 95%CI 4.309~22.132), BMI (2.255, 1.180~4.311), gender (OR=2.788, 1.461~5.323) and drinking (2.306, 1.287~4.134) were significantly related to hypertension. Conclusion The standardized prevalence of hypertension in Hulunbeier Mongolian region is higher than the average prevalence in China, 2002. Old age, abdominal obesity, overweight or obesity, male and alcohol drinking were the main risk factors for hypertension in this region. The government and the health sector should strengthen the health education of healthy lifestyle and health promotion and the control.

Objective To observe the cell apoptosis, oxidative stress reaction and expressions of Bcl-2 and Bax in kid?ney of dietary zinc deficiency mice during growth period, and discuss the mechanism of renal cell apoptosis induced by zinc deficiency. Methods Thirty weaning male mice were randomly divided into zinc-deficient group and zinc-adequate group, and 15 mice for each group. Zinc-deficient group was fed with zinc deficiency diet (0.85 mg/kg), while zinc-adequate group was fed with enough zinc diet (30 mg/kg). The TUNEL method was applied to observe the cell apoptosis, and the apoptotic in?dex was measured. The content of SOD and MDA were detected to observe the oxidative stress reaction in kidney. The ex?pression levels of Bcl-2 and Bax protein were detected by Western blot assay. Results Compared with zinc-adequate group, the cell apoptosis and oxidative stress reaction were increased in zinc-deficient group. The expression of Bcl-2 de?creased, and the expression of Bax increased. The ratio of Bcl-2 and Bax declined in kidney of zinc deficiency mice. Conclu?sion Diet zinc deficiency in growth period may result in the decreased antioxidase, the increased oxidative stress reaction, and the changed Bcl-2 and Bax expression, which promote the occurrence of cell apoptosis in kidney.

Objective To discuss the way of treating accelerated rejection. Methods Seven patients of accelerated rejection were treated by efficient anti-rejection treatment. ResultsSix patients of accelerated rejection were reversed by efficient treatment of anti-rejection. One allograft was removed because treatment was invalid. And six patients were still alive, the longest survival one has reached to 3 years. ConclusionThe treatment emphasis of accelerated rejection should be focused on 3 aspects, including early diagnosis, efficient treatment in time, and paying more attention to any possible complications during the process of treatment.

Objective To study the expression of immunoglobulin-like transcripts 3 (ⅡT3) and ILT4 in peripheral blood dendritic cells (DC) of kidney transplantation recipients and to analyze its significance in immunity hyporesponsiveness of transplantation. Methods Twenty kidney allograft recipients who were survived more than five years were recruited to two groups: renal function stable groups, chronic rejection groups, and 10 healthy volunteers served as a control group. The peripheral blood mononuclear cells (PBMC) were stimulated with granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin 4 (IL-4) and immature DC were obtained. The expression of ILT3 and ILT4 was detected by using flow cytometry. The level of HLA-G5 in serum was determined by using enzyme linked immunosorbent assay. Results ILT3 expression in renal function stable group was increased and decreased in chronic rejection groups as compared with control group (P<0.05),but ILT4 expression had no significant difference among all groups. HLA-G5 in serum was significantly increased in renal function stable group as compared with other groups. Conclusion Expression of ILT3 and HLA-G was increased in the kidney transplantation recipients with stable renal function and long-term survival, suggesting that they may play an important role in inducing and maintaining periphery immune tolerance.
