New posture equilibrometer for the diagnosis of vestibular disease

Summary The vestibulospinal level of vestibular function is commonly neglected in the evaluation of vertiginous patients. We have now developed a new posture equilibrometer. A transducer is placed on the head of the subject being tested. With this meter we can record body swaying, X (left-right) and Y (fore-aft) components of angular displacement, angular velocity, and angular acceleration. A detailed analysis of the data can be made by having patients keep their eyes either open or closed during the Romberg test. The head is turned left or right in this test, while the eyes are opened and closed in the Mann test. The posture equilibrometer has enabled us to evaluate more precisely vestibulospinal function and sensory interactions. Offprint request to: N. C. Zhong

孤立性左肝胆管结石并肝管狭窄的外科治疗

目的总结近２０年来孤立性左肝胆管结石并发左肝胆管狭窄的临床治疗体会．方法原发性肝胆管结石１０１８例，年龄２７～７２岁，其中孤立性左肝胆管结石１３３例，手术治疗１１２例，对其临床资料进行回顾性分析，包括各肝管狭窄并发率，术前各项检查确诊率，手术治疗方式，再狭窄率．结果左肝管狭窄的发生率为５９８％，左外肝管和左内肝管分别为８４０％和８４８％，均以重度狭窄为主．狭窄切开整形后高位胆肠吻合术是处理左肝管狭窄的常用手术方式（５２２％），远期再狭窄率为１７１％；左半肝切除术施实率为１９４％，再狭窄率为００％；狭窄整形术和狭窄扩张术的施实率分别为９０％和１９４％，再狭窄率分别为５００％和９２３％．左外肝管狭窄通常采用肝段或肝叶切除术（７８７％），而左内肝管狭窄的处理则通常采用非左半肝切除术（８４８％）．左内肝管狭窄的术前／后影像学确诊率明显低于左肝管和左外肝管，平均确诊率依次２５９％，９３３％和８７９％．结论二级肝管狭窄是孤立性左肝管结石的常见并发症，肝叶或肝段切除术是其首选治疗原则．过多依赖非肝叶／段切除术和不适当的肝段切除术是遗留狭窄和远期疗效差的重要原因

正常人及胃癌患者胃蛋白酶原C基因多态性研究

以ＰＧＣ３０１为探讨，对１０例胃癌组织及１１例正常人体组织基因组ＤＮＡ中胃蛋白酶原Ｃ基因的ＥｃｏＲ Ｉ限制性片段长度多态性作了观察分析。发现在正常人体有三种常见等位片段，分别为２０ｋｂ、５．７ｋｂ及３．６ｋｂ；一种稀有片段，３．５ｋｂ。在胃癌患者，未发现与正常人体不同的等位片段。但是，稀有片段及稀有杂交带型的出现频率高于正常组。这一结果对深入探讨胃蛋白酶原Ｃ基因稀有片段及稀有杂交带型对胃癌的诊断价     

硫代葡萄糖甙对碘代谢和甲状腺的影响

猪饲喂８％～１６％英籽饼日粮，平均每日从日粮中摄入９１９．４２～１４１６．０２ｍｇ硫代葡萄糖甙。在连续饲喂１２０天后，其甲状腺肿大，甲状腺滤泡和甲状腺上皮细胞显著增生，细胞质内缺乏分泌颗粒和溶酶体，细胞顶端密集微绒毛；滤泡腔内胶质周边部具有大量吸收空泡，分泌功能旺盛。Ｔ＿４和Ｔ＿４／Ｔ＿３比值明显升高，甲状腺功能亢进。若日粮中增加给碘量和服用解毒剂，猪甲状腺的组织形态学和超微结构接近正常，Ｔ＿４和／Ｔ＿４／Ｔ＿３比值亦趋于正常。     

气功对冠心病人CM_5ST段/心率斜率的影响

37名冠心病患者随机分为气功治疗组(22人)和对照组(15人)。气功治疗组接受12周动功治疗,对照组接受安慰剂治疗,治疗前后均测定CM_5 ST段/心率斜率。结果发现动功治疗组CM_5 ST段/心率斜率减少,而对照组不变或增大,两组有显著性差异,ST段下移及常规分级运动试验其它指标在两组间无显著差异。表明CM_5ST段/心率斜率是一个敏感的心肌缺血指标。     

Clinical diagnosis of trauma from occlusion and its relation with severity of periodontitis

The purpose of the present study was to determine the reliability of several selected signs of trauma from occlusion and their relations with severity of periodontitis. 32 moderate to advanced chronic periodontitis patients participated in the study. All teeth present were evaluated for various abnormal occlusal contacts, signs of trauma from occlusion, and the severity of periodontitis. Standardized periapical radiographs were also taken for each tooth. The results demonstrated that: (1) no significant difference occurred in probing pocket depth (PD), clinical attachment loss (AL), or percentage of alveolar bone height (BH) between teeth with and without various abnormal occlusal contacts, i.e., premature contacts in centric relation occlusion, non-working contacts in lateral excursions, premature contacts of anterior teeth or posterior protrusive tooth contacts; (2) teeth with either significant mobility, functional mobility, or radiographically widened periodontal ligament space (PDLS) had deeper PD, more AL and lower BH than teeth without these signs, while teeth with pronounced wear or radiographically thickened lamina dura had less AL than teeth without these findings; (3) 2 combined indices, i.e., the trauma from occlusion index (TOI) and the adaptability index (AI), were proposed for the identification of occlusal trauma and the response of periodontium to excessive biting forces in heavy function, respectively; TOI-positive teeth exhibit deeper PD, more AL and less osseous support than TOI-negative teeth; however, AI-positive teeth had less AL and more osseous support than AI-negative teeth; (4) with identical attachment level, TOI-positive teeth had less osseous support than TOI-negative teeth while the magnitude of difference became greater with an increase of attachment loss.
