羊水细胞培养宫内诊断的应用(附120例分析)

报告120例羊膜腔穿刺羊水细胞培养结果:在成功的99例中,发现二例染色体异常,核型为47,xy,+18和46,xx/47,xx,+F,在21例失败中出现一例眼球畸形。培养成功率为82.5%;染色体异常检出率为2.02%。无一例因羊膜腔穿刺而导致流产,但出现一例轻度羊水栓塞合并症。并对羊水细胞培养在产前宫内诊断中应用价值及术后并发症进行了讨论。     

加压滑动鹅头钉治疗股骨转子间骨折的临床与实验研究

探讨加压滑动鹅头钉在治疗股骨转子间骨折中的作用。临床应用４５例。男３４例，女１１例。平均年龄６１岁。稳定型１３例，不稳定型３２例。经临床应用和生物力学实验测定，结果表明：（１）对不稳定型转子间骨折，恢复小转子区内后侧皮质骨的连续性在骨折的稳定中具有重要作用。（２）内后侧骨折块解剖复位，加压螺丝钉固定或大转子骨折端加压螺丝钉固定能显著增强加压滑动鹅头钉的固定作用，明显提高不稳定型转子间骨折的术后稳定性。（３）该装置设计合理，性能坚固，对转子间骨折具有很强的固定作用，能有效地达到早期下床和避免长期卧床的目的，是目前临床最理想的内固定装置。

慢性活动性肝炎中单核性细胞超微形态研究

经电镜观察,慢活肝中主要为淋巴细胞及单核巨噬细胞浸润。淋巴细胞分3型,通过4种方式与肝细胞接触,可能代表杀伤肝细胞的动态过程。与肝细胞接触的主要为起细胞毒作用的T_8~+Ⅱ型淋巴细胞及单核巨噬细胞。多数T_4~+淋巴细胞为Ⅰ型淋巴细胞,可能为T辅助细胞。在肝细胞损伤中,淋巴细胞及单核巨噬细胞均起重要作用。     

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.

第一掌背动脉双叶皮瓣在手外科中的应用

我们设计主要以第1掌背动脉为蒂的手背双叶皮瓣,同时修复两个部位的手部皮肤缺损和拇指再造,共10例均获成功。皮瓣面积最小10cm×3cm,最大13cm×5cm,蒂宽1.5cm×2.5cm。皮瓣每叶面积最小为3.5cm×2cm,最大6cm×3cm。文中介绍了本皮瓣的解剖学基础,并对其手术适应证和优缺点进行了讨论。     

益肾化浊注射液对慢性肾功能衰竭大鼠残余肾中细胞因子含量的影响

通过观察益肾化浊注射液对5／6肾切除大鼠残余肾中细胞因子含量的影响，益肾化浊注射液延缓慢性肾功能衰竭（CRF）模型大鼠肾功能减退的作用机理。结果显示：益肾化浊注射液可以降低5／6肾切在鼠血清肌,尿素氮（P＜0．01），下调肾组织中白细胞介素－1（IL－1）（P＜0．05），白细胞介素－8（IL－8）（P＜0．05）及肿瘤坏死因子（TNF）（P＜0．05）的总体水平，说明益肾化浊注射液可以通过下调5／6肾切除大鼠残余肾中相关细胞因子含量，抑制促炎细胞因子对肾脏的损害，从而延缓CRF的进展。
