血绒毛膜促性腺激素β亚单位在早期诊断异位妊娠中的作用

异位妊娠又名宫外孕，是指受精卵种植在子宫腔以外部位的妊娠。近年来国内外文献报道异位妊娠发病率呈上升趋势，可能与性病、流产等高危因素增加、助孕技术广泛开展等有关。异位妊娠在早期与先兆流产有时不易鉴别，为了探讨血绒毛膜促性腺激素β亚单位（β-hcG）值在早期诊断异位妊娠中的价值，我们对比分析研究了同期住院的异位妊娠和先兆流产患者的血β-hcG值。

Changes in T .lymphocyte subsets after severe traumatic brain inJury

BACKGROUND： Besides local changes of cranial parenchymal cells, hemorrhage, etc., severe traumatic brain injuries also cause the changes of total body fluid and various functions, and the changes of lymphocytes and T lymphocyte subsets should be paid more attention to. OBJECTIVE： To reveal the changing laws of T lymphocyte subsets after severe traumatic brain injury, and compare with mild to moderate brain injury. DESIGN： A comparative observation. SETTINGS： Department of Neurosurgery, Longgang District Buji People＇s Hospital of Shenzhen City; Central Laboratory of Shenzhen Hospital of Prevention and Cure for Chronic Disease. PARTICIPANTS： All the subjects were selected from the Department of Neurosurgery, Longgang District Buji People＇s Hospital of Shenzhen City from August 2002 to August 2005. Thirty patients with severe brain injury, whose Glasgow coma score （GCS） was ≤ 8 points, were taken as the experimental group, including 21 males and 9 females, aging 16 - 62 years. Meanwhile, 30 patients with mild traumatic brain injury were taken as the control group （GCS ranged 14- 15 points）, including 18 males and 12 females, aging 15 -58 years. All the subjects were in admission at 6 hours after injury, without disease of major organs before injury Informed consents were obtained from all the patients or their relatives. METHODS： （1） The T lymphocytes and the subsets in peripheral blood were detected with immunofluorescent tricolor flow cytometry at l, 3, 7 and 14 days after injury in both groups. （2） The conditions of pulmonary infections were observed at 4 days after injury. The differences of measurement data were compared with the t test. MAIN OUTCOME MEASURES： Changes of T lymphocytes subsets at 1 - 14 days after severe and mild or moderate traumatic injury. RESULTS： Finally, 28 and 25 patients with mild to moderate traumatic brain injury, whereas 25 and 21 patients with severe traumatic brain injury were analyzed at 7 and 14 days respectively, and the missed ones died due to the development of disease. （1） Changes of T lymphocyte subsets： At 1 and 3 days after injury, CD3, CD4, CD8, CD4/CD8 began to decrease, whereas CD8 increased in the experimental group, which were very significantly different from those in the control group （t =2.77 - 3.26, P 〈 0.01）, and began to recover at 7 days, which were significantly different from those in the control group （t = 2.06 - 2.24, P 〈 0.05）, and generally recovered to the normal levels at 14 days （P 〉 0.05）. （2） Conditions of pulmonary infections： At 4 days after injury, the rate of pulmonary infection was significantly different between the experimental group and control group [73% （22/30）, 0, x2=37.29, P 〈 0.01]. CONCLUSION： Patients with severe traumatic brain injury suffer from damages of cellular immune function at early period （within 7 days）, and they are easily to be accompanied by pulmonary infections.     

叉头蛋白、p66shc与长寿

p66shc是原癌基因shc编码的蛋白，敲除p66shc增加由H202和紫外线诱发的细胞凋亡的抵抗。P66shc^-／-小鼠可增加对百草枯的抵抗和寿命延长。FKHRL1和DAF16是叉头蛋白转录因子家族成员，适当增加叉头蛋白的转录活性可延长寿命，而它的磷酸化可抑制其转录活性。氧化应激可导致浓度依赖的FKHRL1的磷酸化。p66shc^-／-细胞在H202处理后FKHRL1的磷酸化无明显改变，表明氧化应激修饰的叉头蛋白的磷酸化的调节需要p66shc的参与。     

急性冠状动脉综合征患者血清高敏感C-反应蛋白检测的临床分析

目的:观察急性冠脉综合征(ACS)患者血清高敏感C- 反应蛋白(hs CRP)水平的变化并与稳定型心绞痛患者比较,分析CRP与ACS的关系。方法:6 7例经冠状动脉造影证实为冠心病患者分为稳定型心绞痛及ACS二组,分别测定CRP的血清水平并进行分析。结果:ACS患者CRP水平较稳定型心绞痛组明显增高,P <0 .0 1,差异有统计学意义。结论:CRP参与了ACS的发生发展过程。动脉粥样硬化斑块破裂是ACS发生的重要因素。炎症过程在此过程中起关键性作用。早期识别不稳定斑块的存在对转变病程和减少病死率具有十分重要的临床意义。寻找不稳定粥样斑块血清标志物是近年的研究热点。本组通过观察ACS和稳定型心绞痛患者hs- CRP的变化。从临床的角度进行探讨CRP在ACS中的作用。     

亚低温治疗重型颅脑损伤病人的临床观察及护理

目的探讨如何降低重型颅脑损伤病人的致残率和病死率。方法2004年10月至2006年9月，我科采用北京康联医用设备研究所生产的ICE—I系列医用控温毯，对高热病人实施亚低温（32-34℃）治疗58例。亚低温治疗期间密切观察意识、瞳孔、生命体征、颅内压的变化及上消化道出血征象，发现异常及时处理；并加强基础护理、严格无菌操作、定时翻身按摩、预防褥疮及冻疮、防止感染。结果治愈30例．轻残12例，中、重残4例，死亡12例。较2004年10月以前同类病人的病死率同比下降了14％。结论低温治疗可使机体处于休眠和低温状态，从而降低组织代谢，特别是降低脑代谢，减少耗氧量，因而可防止或减轻脑水肿，降低颅内压力，改善脑的缺氧状态，有利于受伤脑细胞的恢复，从而使病死率降低。

人细小病毒B19,B族链球菌及解脲支原体与早产关系的研究

目的研究人细小病毒B19，B族链球菌及解脲支原体与早产的关系。方法应用聚合酶链反应技术(PCR)检测早产350例及足月产500例患者胎盘，胎膜中的3种病原体DNA。结果发现早产组人细小病毒B19，B族链球菌和解脲支原体的感染率分别为14．88％、23．24％及20．53％，明显高于对照组。早产组两种及两种以上病原体感染者92例，占总数26．28％，而对照组无多种病原体感染。结论早产可以由一种病原体感染引起，也可以是多种病原体感染的后果。人细小病毒B19是引起早产的主要病原体之一。
