烫伤大鼠细胞免疫抑制与肠源性内毒素血症的关系

采用大鼠４０％ＴＢＳＡⅢ度烫伤模型，将动物随机分烫伤对照组和选择性消脱污染防治组，探讨烫伤大鼠全身性细胞免疫抑制与肠源性内毒素血症的关系。结果显示，大鼠４０％Ⅲ度烫伤后脾细胞对促有丝分裂原增殖应答反应、诱生白介素－２（ＩＬ－２）活性及Ｔ细胞亚群（Ｔｈ／Ｔｓ）比值明显下降，预防性进行ＳＯＤ动物，内毒素血症发生率显著降低，脾细胞增殖应答反应和ＩＬ－２活性的诱生能力均明显恢复（Ｐ〈０．０５￣０．０１），     

脾结核的临床特征

目的 探讨脾结核的临床特点、诊断和治疗。方法 回顾性分析经临床、手术及病理证实的11例脾结核的临床特征。结果 11例患者中，男7例，女4例，平均年龄29岁。6例术后证实，5例经内科保守治疗后证实。多数患者表现为发热、消瘦、血沉增快、贫血、脾肿大，B超发现脾脏肿大11例，其中8例脾内多发占位，3例为孤立性占位；7例行CT检查，6例发现脾脏多发性大小不等的结节状低密度灶，1例为单发类圆形低密度影，边缘不清，增强扫描病灶内部无强化；6例患者伴后腹膜、脾门区等淋巴结肿大，5例患者伴其它脏器结核。结论 不明原因发热、消瘦、血沉增快、贫血、脾肿大为脾结核的主要临床表现，腹部B超和腹部CT能对脾结核作出较准确的判断，脾结核患者经正规治疗可治愈。     

垂体后叶素和硝酸甘油联合治疗食管静脉曲张破裂大出血

３０例肝硬化食管静脉曲张破裂大出血患者，用垂体后叶素０．２～０．４Ｕ／ｍｉｎ连续静脉滴注和硝酸甘油含服联合治疗。结果表明，近期止血有效申达８０％，死亡率１０％；无一例出现严重心绞痛和心电图异常。     

原癌基因C－erb B－2蛋白产物在前列腺癌中的表达

应用抗Ｃ－ｅｒｂＢ－２癌蛋白抗体对３０例前列腺癌进行研究，同时选取１０例正常前列腺组织作为对照。结果表明Ｃ－ｅｒｂＢ－２蛋白与肿瘤分化程度有关。并可能对判断其生物学行为，评估预后有重要意义。     

The postoperative recurrence of crohn's disease: An analysis of 37 patients with crohn's disease who underwent endoscopy during initial surgery

A total 37 patients with Crohn's disease who underwent intraoperative endoscopy during resection of the affected intestine were evaluated in this study. The average age of the patients at surgery was 23.2 years. The residual lesions in the remaining intestine identified by intraoperative endoscopy were classified according to their pathologic profiles into three groups: A, B and C. In group A, comprising patients with longitudinal ulcers and/or a cobblestone appearance, 10 of 12 patients had recurrence. In 5 of these 10, the residual lesions were exacerbated and 2 required a further operation. The remaining 5 patients showed recurrence at the site of previous anastomosis and 2 of these 5 required additional surgery.In group B, comprising patients with small ulcers, aphthoid ulcers, or scars, and group C, comprising patients with no residual lesions, recurrence was observed in 13 of 16, and 3 of 9 patients, respectively. The recurrent lesions were all found proximal to, or at the site of previous anastomosis. Additional operations were performed on 3 of the group B patients. The findings of this study revealed that recurrence requiring additional surgery is more frequent at the site of anastomosis, regardless of the endoscopic appearance of the residual lesions.     

巢式聚合酶链反应检测脑脊液中单纯疱疹病毒DNA

应用巢式聚合酶链反应(PCR)检测患者脑脊液(CSF)中单纯疱疹病毒1型(HSV-1)DNA。23例经鞘内HSV-1特异性IgG抗体检测阳性的“HSV-1型性脑炎(HSE)”中19例PCR阳性,4例阴性患者病程均超过1个月。22例IgG阴性的“散发性脑炎”中7例PCR阳性,此7例皆于发病1周内检查CSF,其中2例取材于发病当日。1周后复查7例患者,CSF PCR仍为阳性,IgG皆阴性,提示PCR适用于HSE的早期诊断。

全身(全淋巴)照射后100例医源性急性放射病的临床分析

在造血干细胞移植治疗肿瘤过程中用全身照射（ＴＢＩ）或全淋巴照射（ＴＬＩ）预处理，研究受照不同剂量患者发生医源性急性放射病严重程度，治疗方法和造血恢复及相关合并症。方法１００例患者（白血病９１例，其他肿瘤９例）接受５００～１０００ｃＧｙＴＢＩ或ＴＬＩ和超大剂量化疗作预处理。结果均发生医源性急性放射病，白细胞降至（０～０．１５）×１０９／Ｌ，骨髓空虚，合并各种感染和出血。经造血干细胞移植，抗感染，应用ＧＭ－ＣＳＦ或Ｇ－ＣＳＦ积极支持治疗及保护隔离措施，９２例造血恢复，８例死于不同感染和出血。结论造血干细胞的移植起主要治疗作用，不同造血因子用于治疗急性放射病，可能是一种有希望的方法
