A study on plasma norepinephrine and epinephrine levels in TCM liver syndromes.

The levels of plasma norepinephrine (NE) and epinephrine (E) were determined by HPLC in 220 patients with various TCM liver syndromes, and in 96 healthy subjects as controls. The plasma NE and E contents were higher in patients with liver excess syndromes, including Ganqi Yujie (GQYJ [symbol: see text]) syndrome, Ganyang Shangkang (GYSK [symbol: see text]) syndrome, Ganhuo Shangyan (GHSY [symbol: see text]) syndrome, and Ganyang Huafeng (GYHF [symbol: see text]) syndrome; while they were lower in patients with liver deficiency syndromes, including Ganqixu (GQX [symbol: see text]) syndrome, Ganxuexu (GXX [symbol: see text]) syndrome, and Ganyinxu (GYX [symbol: see text]) syndrome. Futhermore, when Ganshen Yinxu (GSYX [symbol: see text]) syndrome was turned into GYSK and then into GYHF, the plasma NE and E contents increased in order of precedence; while when GQYJ was turned into Ganyu Pixu (GYPX [symbol: see text]) syndrome, both NE and E contents decreased. The results suggest that the plasma NE and E contents are reliable objective parameters for the study of pathophysiological basis of the liver excess and liver deficiency syndromes, and the liver-kidney and liver-spleen interrelated syndromes.     

不同膳食特点地区中老年人血红蛋白及其与膳食营养的关系

测定分析不同膳食特点地区975例年龄45～74岁中老年人的血红蛋白及其与膳食营养素的关系。结果牧民及城市居民贫血率低，北京及新疆托里分别为7.6％和4.6％。男性比女性血红蛋白高，血红蛋白随年龄增加而降低。相关分析结果血红蛋白与膳食热能、蛋白质、动物蛋白质与总蛋白质比值呈显著正相关。结果说明血红蛋白可用于中老年人营养状态监测。     

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     

综合医院心理咨询门诊儿童咨客分析

目的；了解综合医院心理咨询门诊儿童咨客的特点。方法：总结中山大学附属三院心理咨询门诊近3年儿童咨客的资料。结果：咨客男女比例为1．96：1，咨客人数随着年龄的增长而增加，女童中13－16岁的比例男童大，5－8岁和9－12岁的比例较男童小。广州市内外的咨客比例为1．38：1，不同年龄儿童咨客的居住地构成是有差异的。最常见的病种是精神分裂症，神经症、精神发育迟滞，儿童多动症，单纯咨询和品行障碍，不同年龄，不同性别的儿童咨客的疾病构成是有差异的。结论：综合医院心理咨询门诊与儿童心理咨询门诊的儿童咨客是有差异的。

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.
