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.     

Vitapex糊剂用于患儿根尖诱导成形术的护理配合

根尖诱导成形术（apexficaotion，AP）是指牙根未完全形成之前，在消除感染或尖周炎症的基础上，用药物诱导根尖部牙髓和俄根尖周组织，使牙根继续发育并使根尖形成，行永久性充填。2002年-2005年我科将Vitapex糊剂用于儿童患牙行根尖诱导成形术，效果较好：现将护理配合介绍如下。     

甲基强的松龙对低温保存大鼠肝脏的保护作用

应用Ｗｉｓｔａｒ大鼠肝脏离体灌流模型，用ＣＭＵ—１号液，含有甲基强的松龙的ＣＭＵ—１号液，以及缺血前预用甲基强的松龙后再用ＣＭＵ—１号液分别对肝脏进行灌洗保存。检测ＬＤＨ、ＡＬＴ、肝组织匀浆ＳＯＤ活性和ＭＤＡ含量，并观察肝组织结构。结果表明：甲基强的松龙对低温保存的离体大鼠肝脏具有保护作用     

老年急重症胆管炎临床分析

目的：探讨重症胆管(ACST)患者的临床特点及死亡原因。方法：分析我院近十五年来收治46例ACST的治疗情况。结果：手术41例．非手术5例，死亡9例，其中手术治疗死亡6例。结论：老年ACST患者，伴发病多，死亡率高，及时就诊，早期应用大量激素，选择适宜手术方法是降低死亡率的关键。     

New surgical technique of left ventricular free wall rupture: double patch sealing method.

We experienced two cases of left ventricular free wall rupture (LVFWR) following acute myocardial infarction (AMI). Case 1, with the blowout type of LVFWR was initially closed by direct suture, followed by hemostasis using a double patch sealing method (DPS) by which the tear was doubly sealed with large and small bovine pericardium patches to which GRF glue was applied. Case 2 with the oozing type of LVFWR was treated only using DPS. Complete hemostasis was achieved in both cases, and aneurysmal dilatation or constrictive heart failure were not detected by postoperative left ventriculography. Therefore, DPS may be useful for treating LVFWR following AMI.     

学习不良儿童的智力、行为及非智力因素的对照研究

选用《ＦＡＴ》筛选出学习不良儿童４１名，学习优秀儿童３５名。对二组儿童进行ｗｉｃｓ-Ｒ智力测试：不良组儿童ＩＱ低于优秀组儿童（Ｐ＜０．０５），但不良组ＩＱ＞１２０有６名（１４．６０％），优秀组ＩＱ＜９０有５名（１４．５０％）。父母教育方法调查结果表明：优秀组父母偏重意志、兴趣培养，不良组父母着重成绩或者放任，二组父母教育方式存在显著差异（Ｐ＜０．０５）。优秀组儿童在学习中比不良组儿童具有较强的非智力个性心理因素（Ｐ＜０．０５）。《ＣＢＣＬ》儿童行为量表测验结果提示：学习不良儿童比优秀儿童行为问题较为突出（Ｐ＜０．０５）。

雄性大白鼠球海绵体肌和坐骨海绵体肌的运动神经元—HRP法研究

本实验用HRP注射于大白鼠的一侧球海绵体肌和坐骨海绵体肌后,在脊髓腰骶段的不同平面可观察到支配该两肌的运动神经元胞体出现标记并具有一定的局部定位关系。支配球海绵体肌的运动神经元主要位于L_5～S_1的背内侧群,而支配坐骨海绵体肌的运动神经元主要位于背外侧群和腹侧群。本文认为大白鼠腰骶段前角背内侧群和背外侧群同腹外侧群细胞一样,同属于Onuf's核的同源神经细胞。本文还观察了大白鼠腰骶段脊髓前柱细胞的配布。     

视网膜下液对培养的人视网膜色素上皮细胞、神经胶质细胞及成纤维细胞生长的刺激作用

目的:研究视网膜下液(subrefinal fluid,SRF)对增殖性玻璃体视网膜病变(proliferativeVitreoretinopathy，PVR)的多种细胞增殖的影响. 方法；采用直接细胞计数和_³H-TdR掺入率测定DNA合成两种方法观察28例孔源性视网膜脱离患者SRF对培养的人视网膜色索上皮(retinal pigment epithelium，RPE)细胞，视网膜神经胶质(retinal glia，RG)细胞及成纤维细胞(flbroblast，FB)生长刺激作用． 结果：所有标本均具有刺激RPE细胞、RG细胞及FB增殖和DNA合成能力，增殖率范围分别在基线上52.5%～233.3%、36.4%～177.8%、55.4%~277.8%之间．SRF促细胞增殖串在三种细胞间比较无显著差异。 结论：SRF具有促多种细胞增殖的能力，推测SRF中含有促细胞增殖的活性物质。 （中华眼底病杂志，1996，12：233-235）
