深圳市福田区暗娼艾滋病KAP调查分析

目的：探讨暗娼艾滋病KAP的现状，为艾滋病预防控制中的咨询、外展及其它健康教育活动提供依据。方法：在“城中村”中随机抽取55位暗娼，由经过专门培训的调查员调查并采血检验。结果：暗娼艾滋病平均知晓率为73．88％；与艾滋病相关的高危行为，呈现低龄化、职业化的倾向；为了预防艾滋病，绝大部分暗娼愿意坚持使用安全套，但实际情况并不如人意；暗娼获得艾滋病知识及相关服务并不方便；梅毒检出率为9．09％。结论：打工者的性权利长期被忽视，使卖淫拥有很大的市场，这是暗娼们乃以存在并长久不衰的重要原因之一；暗娼艾滋病知晓率有了较大提高，可能与深圳市开展艾滋病防制工作较早、力度较大有关；安全套使用率还有待提高：艾滋病外展服务亟待开展与加强。

Longitudinal Analysis of Severe Acute Respiratory Syndrome (SARS) Coronavirus-Specific Antibody in SARS Patients

The serum antibodies to severe acute respiratory syndrome (SARS) coronavirus of 18 SARS patients were checked at 1 month and every 3 months after disease onset. All of them except one, who missed blood sampling at 1 month, tested positive for the immunoglobulin G (IgG) antibody at 1 month. Fifteen out of 17 tested positive for the IgM antibody at 1 month. The serum IgM antibody of most patients became undetectable within 6 months after the onset of SARS. The IgG antibody of all 17 patients, whose serum was checked 1 year after disease onset, remained positive.     

体重指数、腰围、腰臀比与血压、血糖、血脂关系的探讨

目的 探讨体重指数(BMI)、腰围(WC)、腰臀比(WHR)与代谢性因素的关系.方法 对镇江市居民基线资料的1108例对象按BMI、WC、WHR分组.在正常体重、超重、肥胖;腰围正常、腰围过大;腰臀比正常、腰臀比过大各组中,比较收缩压(SBP)、舒张压(DBP)、血糖(FBG)、总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)的水平.结果 不论男性女性组,超重肥胖、腰围过大组,血压、血糖、血脂水平与正常组比较均明显升高;腰臀比过大组与正常组比较,男性组TG、FBG明显升高;HDL-C明显降低;女性组TG、FBG、SBP明显升高,HDL-C明显降低.结论 BMI、WC、WHR指标与代谢性因素密切相关;BMI、WC在提示肥胖程度方面优于WHR指标.     

Serial CT findings of Paragonimus infested dogs and the Micro-CT findings of the worm cysts.

OBJECTIVE: To investigate the serial CT findings of Paragonimus westermani infected dogs and the microscopic structures of the worm cysts using Micro-CT. MATERIALS AND METHODS: This study was approved by the committee on animal research at our institution. Fifteen dogs infected with P. westermani underwent serial contrast-enhanced CT scans at pre-infection, after 10 days of infection, and monthly thereafter until six months for determining the radiologic-pathologic correlation. Three dogs (one dog each time) were sacrificed at 1, 3 and 6 months, respectively. After fixation of the lungs, both multi-detector CT and Micro-CT were performed for examining the worm cysts. RESULTS: The initial findings were pleural effusion and/or subpleural ground-glass opacities or linear opacities at day 10. At day 30, subpleural and peribronchial nodules appeared with hydropneumothorax and abdominal or chest wall air bubbles. Cavitary change and bronchial dilatation began to be seen on CT scan at day 30 and this was mostly seen together with mediastinal lymphadenopathy at day 60. Thereafter, subpleural ground-glass opacities and nodules with or without cavitary changes were persistently observed until day 180. After cavitary change of the nodules, the migratory features of the subpleural or peribronchial nodules were seen on all the serial CT scans. Micro-CT showed that the cyst wall contained dilated interconnected tubular structures, which had communications with the cavity and the adjacent distal bronchus. CONCLUSION: The CT findings of paragonimiasis depend on the migratory stage of the worms. The worm cyst can have numerous interconnected tubular channels within its own wall and these channels have connections with the cavity and the adjacent distal bronchus.

The upregulation of glial glutamate transporter-1 participates in the induction of brain ischemic tolerance in rats.

Glial glutamate transporter-1 (GLT-1) plays an essential role in removing glutamate from the extracellular space and maintaining the glutamate below neurotoxic level in the brain. To explore whether GLT-1 plays a role in the acquisition of brain ischemic tolerance (BIT) induced by cerebral ischemic preconditioning (CIP), the present study was undertaken to observe in vivo changes in the expression of GLT-1 and glial fibrillary acidic protein (GFAP) in the CA1 hippocampus during the induction of BIT, and the effect of dihydrokainate (DHK), an inhibitor of GLT-1, on the acquisition of BIT in rats. Immunohistochemistry for GFAP showed that the processes of astrocytes were prolonged after a CIP 2 days before the lethal ischemic insult, which could protect pyramidal neurons in the CA1 hippocampus against delayed neuronal death induced normally by lethal ischemic insult. The prolonged processes extended into the area between the pyramidal neurons and tightly surrounded them. These changes made the pyramidal layer look like a 'shape grid'. Simultaneously, the prolonged and extended processes showed a great deal of GLT-1. Western blotting analysis showed significant upregulation of GLT-1 expression after the CIP, especially when it was administered 2 days before the subsequent lethal ischemic insult. Neuropathological evaluation by thionin staining showed that DHK dose-dependently blocked the protective role of CIP against delayed neuronal death induced normally by lethal brain ischemia. It might be concluded that the surrounding of pyramidal neurons by astrocytes and upregulation of GLT-1 induced by CIP played an important role in the acquisition of the BIT induced by CIP.
