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.     

带蚓状肌的游离足趾再造拇、手指

自１９７２年以来，在游离足趾再造拇、手指手术中，应用足趾蚓状肌与缺损拇、手指蚓状肌残端或关节囊进行缝合的方法共完成手术３００例，由于再造拇、手指的蚓状肌得到修复，既改善了其指间关节屈曲畸形，又防止了掌指关节的过伸。术后随访１－２２年，再造拇、手指的外形及功能均满意。     

早期应用无创性通气治疗老年Ⅱ型呼吸衰竭的护理

目的　探讨应用无创性通气治疗老年Ⅱ型呼吸衰竭的护理。方法　在常规治疗的同时 ,实验组与对照组分别应用无创通气和呼吸兴奋剂治疗 ,观察 2组患者治疗前、后、治疗间歇期动脉血气变化及康复例数。结果　实验组患者治疗后血气明显改善 (P <0 .0 1) ,康复例数明显多于对照组 (P <0 .0 1)。结论　应用无创通气可促进呼吸衰竭患者的康复 ,护士要加强对患者的心理支持 ,严密监测生命体征 ,保持呼吸道通畅 ,熟练掌握无创通气呼吸机的性能、使用方法 ,防止并发症     

强化胰岛素治疗的2型糖尿病患者胰岛素脱离与否相关因素分析

目的比较强化胰岛素治疗的2型糖尿病患者在脱离胰岛素治疗和继续胰岛素治疗时的临床特点,分析脱离胰岛素的相关因素。方法统计66例入院的2型糖尿病患者的患病时间,检测开始胰岛素强化治疗、治疗过程、治疗结束时的糖化血红蛋白(HbA1 c)、体重指数(BM I)、胰岛素用量,观察脱离胰岛素所需时间。结果34例患者脱离胰岛素治疗,32例继续治疗,两组患者在年龄、治疗开始时间、BM I、HbA1 c差异均无统计学意义,而患病时间比较差异有统计学意义(P<0.05),脱离时的胰岛素用量和HbA1 c比继续治疗患者显著减低(P<0.01)。结论患病时间长短是胰岛素脱离与否的重要因素,胰岛素投入量及HbA1 c数值对脱离胰岛素与否有积极作用。

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.
