Corticotropin-Releasing Factor Reduces Lipopolysaccharide-Induced Pulmonary Vascular Leak

Previous studies have suggested that corticotropin-releasing factor (CRF) has immunoregulatory effects in addition to its neuroendocrine role. We examined the ability of CRF to inhibit lipopolysaccharide (LPS)-induced pulmonary vascular leak in vivo. Female BALB/C mice were treated with either normal saline (NS) or CRF prior to injection with LPS. Pulmonary vascular leak was inhibited by CRF as assessed by measurement of lung wet-to-dry ratios. The stress-induced increase in serum corticosterone levels in mice injected with LPS alone was not further increased by treatment with CRF. This indicates that the effect of CRF was not mediated centrally by stimulation of endogenous steroid release. Histologic examination of the lungs revealed that leukocyte infiltration was significantly depressed in CRF-treated mice thus confirming the protective effect of CRF. In addition, a modest prolongation of survival was demonstrated in CRF-treated mice following challenge with LPS (p=.08). These data indicate the potential utility of CRF as a modulator of pulmonary vascular leak.

日晒海盐工人机体内高镁反应

报道福建某盐场从事日晒海盐生产人工机体内高镁对心血管系统的影响，通过现场空气、饮水、主良的镁含量测定，并对进入机体途径进行分析，得出空气、卤水接触、饮水为机体镁增高的主要来源。不同对象头发镁含量测定结果显示，以接触卤水、劳动强度大的盐工最高，并随机体内镁含量增高，出现血压偏低、心率减慢、心电图Ｐ－Ｒ间期延长、ＱＲＳ波增宽、Ｔ波高尖等机体高镁反应，与临床高镁血症相似。

16例胸膜间皮瘤临床分析

１６例胸膜间皮瘤，其中１例有石棉接触史，占６．１７％；＞４０岁者占８１．５％。主要临床表现为胸痛、气短、咳嗽、低热和胸腔积液，临床上易误诊为结核性胸膜炎、肺癌胸膜转移等。胸部ｘ线检查及胸部ＣＴ对该病的诊断有帮助，大都有特征性表现。确诊靠针刺胸膜活检及开胸活检。胸膜间皮瘤的治疗主要采用手术、放疗和化疗，对于局限型治疗首选手术切除。肿瘤的良、恶性、疾病的分期及治疗与预后有一定关系。     

CT-guided stereotactic injection of radionuclide in treatment of brain tumors.

140 patients with brain tumor were treated by CT-guided stereotactic injections of radionuclides, such as Aurum-198 (198 Au), Phosphorus-32 (32 P) and Yttrium-90 (90Y). Of these patients aged from 3 to 67 years (average 37), 64 were male and 76 female. Astrocytoma was found in 75 patients, craniopharyngioma in 46, metastatic carcinoma in 7, meningioma in 5, germinoma in 4 and pituitary adenoma in 3. The tumors were located in the deep part or functionally critical area of the brain. After 267 times of injection of colloidal isotopes, no major adverse effects or complications occurred. Follow-up for 6 to 48 months showed improvement in symptoms in 104 (74.3%) patients and CT scanning showed the diminished tumors.

     

1977～1990年同济医科大学新生视力状况分析

用统计学方法对14年来（1977～1990年）我校6746名新生（13492只眼）的视力状况进行分析。结果表明；新生正常视力逐年减少，视力不良率相应上升（P＜0.001）。城市学生的视力比农村学生差，男生的视力优于女生（P＜0.001）。17～19岁组的视力明显低于其他年龄组（P＜0.001）。高考分数线升高与正常视力者减少呈明显负相关；而与视力不良者增加呈正相关（P＜0.001,＜0.05）。本文认为近距离用眼持续时间过长及环境视域小等是引起视力不良的主要原因。

4℃保存外周血造血干细胞动态观察

本文对4℃条件下不同时间保存后的外周血造血干细胞(peripheral bloodhematopoietic stem cells,PBHSC)数进行了动态观察。在本实验中以定向造血祖细胞(CFU-GM)作为观察PBHSC的指标。结果表明:随着保存时间的延长,PBHSC集落数逐渐下降;0小时与24小时保存后的干细胞数无显著差异;24小时与48、72、96、120小时保存后的干细胞数有高度显著差异;48小时与72、96、120小时保存后的干细胞数无显著差异。同时发现,红细胞的存在有利于PBHSC的4℃保存。
