双头加压螺纹钉贴股骨距内固定治疗股骨颈骨折

在Ｘ光电视下采用双头加压螺纹钉贴股骨距内固定治疗新鲜股骨颈骨折４２例，随访平均２．５年，其中１６例随访３年以上，骨折愈合率９５．２％，骨折不愈合并股骨头缺血性坏死率４．７６％。认为加压螺纹钉贴股骨距内固定可使钉的受力由较大剪应力变为较大轴向力承受，减少骨折处的剪应力，并加压于骨折端能促进骨折愈合。具有操作简单、进钉准确、创伤小、固定牢靠、并发症少等优点。     

大鼠气管上皮细胞体内—体外转化模型的研究

本研究建立了大鼠气管上皮细胞体内－体外转化模型，大鼠气管内滴注苯并芘，三天后处死大鼠，消化气管上皮细胞，接种于无血清完全培养基。细胞形成集落后，换为选择培养基继续培养五周，统计转化率。结果显示，２５ｍｇ／ｋｇ和５０ｍｇ／ｋｇ的苯并芘可诱导大鼠气管上皮细胞转化及微核增加，用同样方法研究了煤焦沥青提取物，结果表明，剂量为８ｍｇ／ｋｇ和２５ｍｇ／ｋｇ的煤焦沥青提取物能明显诱导大鼠气管上皮细胞转化。     

大鼠脑缺血时脑细胞膜磷脂含量变化

采用SD大鼠一侧大脑中动脉阻断致局限性脑缺血模型。脑缺血后迅速断头置于液氮中,HPLC外标定量法测定各磷脂组分。观察脑缺血1、5、15、60、360min时脑细胞膜磷脂含量变化。结果显示,PI在缺血早期显著低于对照组(P<0.01～0.05);PE、PC早期仅呈下降趋势,PE在缺血60min组、PC缺血360min组显著低于对照组(P<0.01～0.05)。PS在缺血全过程中变化轻微(P>0.05)。提示磷脂降解与脑缺血存在一定关系,缺血早期首先出现脑细胞膜功能磷脂降解,膜结构磷脂则在缺血后期出现显著变化,且PE较PC优先降解。     

STUDIES OF HLA-D REGION DNA POLYMORPHISM IN INSULIN-DEPENDENT DIBETES MELLITUS

Restriction fragment length polymorphisms (RFLPs) of peripheral leucocyte DNA in insulin-dependent diabetes mellitus (IDDM) patients and in controls were studied with Southern blot analysis. IDDM has been reportedly associated positively with the HLA-DR3 and-DR4 in Caucasians, with the HLA-DR3 and-DR9 in Chinese, and negatively with the HLA-DR2 in both Caucasians and Chinese, Using an HLA-DQβcDNA probe, an EcoRI 2.2 kb fragment is found associated with DR2 controls (r = 0.78, P=1×10~(-6)), but not with DR2 IDDM patients, their respective frequencies being significantly different (P=0.02). The authors also report here their new findings that the frequencies of the EcoRI3.0 kb and BamHI3.3 kb fragments are both decreased in the patient group (P=0.0032 and P=0.0018 respectively). This suggested certain kinds of mutation such as partial deletion or others in the IDDM patients might have caused the RFLP pattern change as compared to the normal DNA. RFLPs may provide valuable information in searching for the genetic basis of IDDM.     

中国汉译西医学著作在日本的流传和影响

调查了十九世纪汉译西洋医学著作在日本的出版和流传情况，有９种汉译西洋医学著作曾在日本出版，其中６种曾多次再版，７种有和训或和译本，这些著作曾在日本医生中广泛流传，促进了西洋医学在日本的传播和普及，对日本医学从传统医学向现代医学的转变起过一定的作用。本文还分析了汉译西洋医学著作能够在日本广泛流传的原因     

原发性淀粉样变性的临床病理及电镜观察

淀粉样变性是指淀粉样蛋白在皮肤，粘膜或内脏器官的细胞外沉积引起的一种少见疾病。口腔粘膜中舌粘膜是本病的好发部位。本组４例典型地发生于口腔颌面部的原发性淀粉样变性病例，３例病变部位为舌，１例为皮肤和口腔粘膜同时受累，临床提示有必要进行全身系统检查及追踪随访。并就基临床表现，常规病理，组织化学及电镜进行研究，同时讨论了淀粉样蛋白的光镜，电镜特点，组织学类型生化组成及来源。     

Ultrasound Biomicroscopic Dark Room Provocative Test

Purpose : To compare the clinical application value of Ultrasound biomicrsocpic dark room provocative test with the traditional dark room test in screening primary angle closure glaucoma (PACG).Methods: 22 eyes with PACG in prodromal stage and 30 eyes with deep anterior chamber and wide angle of 15 normal persons were observed in this trail. All 52 eyes were performed traditional dark room provocative test and ultrasound biomicorosopic darkroom test respectively. With different positive diagnostic criteria, the sensitivity of the two methods were compared using chi-squared analysis.Results : After staying in the dark room for 2 hours, In case group, IOP in 10 of 22 eyes rose more than 1. 07kPa(1kPa = 7.5mmHg), in 12 eyes less than 1.07kPa or had no changes; appositional angle closure were found by Goldmann gonioscopy in 8 eyes : 3 eyes in two quadrants, 5 eyes in more than two quadrants; the appositional angle closure was found by UBM in 15 eyes; 3 eyes in one quadrants, 5 eyes in two quadrants, 7 eyes     

穿透性角膜移植联合瞳孔成形术的临床观察

目的观察穿透性角膜移植联合瞳孔成形术的效果。方法４８只眼行穿透性角膜移植术的同时对虹膜缺损进行修复，成形瞳孔。术后随访６～８９个月。结果植片透明者３８只眼（７９．２％），视力恢复０．１以上者３１只眼（６４．６％），瞳孔修复接近正常者４３只眼（８９．６％）。结论穿透性角膜移植联合瞳孔成形术，可减少术后并发症、改善植片的预后及视功能。对波及瞳孔的虹膜缺损，联合行瞳孔成形术效果较好。
