胃癌及不典型增生病变中AgNOR和PCNA的表达

对60例患者的胃标本进行了银染色和免疫组化染色,探讨细胞核仁形成区相关嗜银蛋白（AgNOR）和增殖细胞核抗原（PCNA）在胃癌及不典型增生中的表达。结果表明：胃癌组AgNOR和PCNA的表达明显高于不典型增生组和慢性浅表性胃炎组,而不典型增生组高于慢性浅表性胃炎组,差异均有显著性意义（P＜0．05）。结果提示,AgNOR和PCNA的表达异常,可用于临床判断良性病变与恶性病变的指标之一。     

Effect of Yunqi decoction on esophageal mucosal morphology and esophageal motility in reflux esophagitis patients) on esophageal mucosal morphology and esophageal motility in reflux esophagitis patients

Objective: To observe the effects of Yunqi decoction ( , YQD) on both esophageal mucosal morphology and esophageal motility in patients with reflux esophagitis (RE).Methods: According to syndrome differentiation of traditional Chinese medicine (TCM), 42 RE patients were divided into three groups: disharmony of Liver and Stomach (group D), Deficiency-Cold of Spleen and Stomach (Group DC), Heat Syndrome caused by stagnation of Liver Qi (Group H). No. I, II, III of YQD were taken respectively for 4 weeks. Before and after treatment scores of typical symptoms were collected, gastroscopy was performed and esophageal motility were measured.Results: (1) The symptom remission rate was 81.1%, there were significant differences between the group DC with group D and group H(P < 0.01). (2) The esophageal mucosal healing rate was 61.9%, the effective rate was 90.5%, and the ineffective rate was 9.5%. There were not significant differences of effective rate among the three groups (P>0.05). (3) The changes of esophageal motility: Lower esophageal sphincter pressure (LESP) and average peristaltic pressure (APP) of group D were obviously higher than before treatment (P < 0.05), LESP, gastro-esophageal barrier pressure (GEBP) and peristaltic conduct speed (PCS) of group DC were remarkably higher (P < 0.05). GEBP of group H was improved (P < 0.05). Conclusions: YQD has a good therapeutic effect. It’s not only resolving reflux esophageal symptoms, healing esophageal mucosa, but also improving esophageal motile function.     

慢性肾功能衰竭中医证型标准化研究探讨

本文对２次全国性慢性肾衰中医辨证分型标准进行了分析和总结,并按现行慢性肾衰辨证分型方案对４４４例患者进行证候学研究,列出了慢性肾衰中出现率高且具有鉴别诊断价值的症状及体征,并发现慢性肾衰尿毒症患者其气血阴阳虚损的积分值明显高于其它各期,提出现行方案的不足之处及有待改进的探讨意见     

腺苷心肌保护液对离体大鼠心肌能量代谢及离子含量的影响

为观察腺苷心肌保护液对大鼠心肌ＡＴＰ及离子含量的影响, 采用离体大鼠工作心脏缺氧停搏１２０ ｍ ｉｎ, 采用高钾、高钾＋ 腺苷及腺苷停搏液进行心肌保护。发现停搏末含腺苷的两组ＡＴＰ含量明显高于高钾组, 且复灌后进一步恢复; 各离子含量均能保持平稳。高钾组复灌后细胞内Ｎａ＋ 、Ｃａ２＋ 明显增高伴Ｍｇ２＋ 的减少。结果表明： 腺苷心肌保护液能够改善心肌能量代谢, 维持停搏期间及复灌后细胞内离子含量的稳定, 对缺氧心肌发挥保护作用     

镁对脑缺血早期脑组织中谷氨酸及一氧化氮含量的影响

为研究镁在脑缺血早期对神经元保护作用的机制,用电凝法建立大鼠大脑中动脉缺血模型,在造模前给大鼠注射２０ｇ／Ｌ硫酸镁,观察镁对脑组织中谷氨酸（Ｇｌｕ）及一氧化氮（ＮＯ）含量的影响。结果显示,高浓度镁可明显降低脑缺血皮质中Ｇｌｕ、ＮＯ含量,在缺血组Ｇｌｕ、ＮＯ的峰值浓度分别为９．８７、４４．９７ｎｍｏｌ／ｇ,而在加镁组两者浓度分别为７．６８、３３．９２ｎｍｏｌ／ｇ。提示：镁对脑缺血早期神经元的保护作用与其降低脑组织中Ｇｌｕ及ＮＯ含量有关。     

补偿曲线曲度与弦斜度相关性分析

①目的　统一平衡牙合 ５ 个因素的衡量标准平面和单位,探讨弦斜度与补偿曲线曲度的相关关系。②方法　应用 Ｘ 线立体摄影测量结合计算机技术,对哈尔滨市９９ 例青年的补偿曲线进行测量分析,并以圆心角代表补偿曲线曲度。③结果　弦斜度与圆心角呈高度正相关（ｒ＝ ０．９４７１, Ｐ＜ ０．０１）。方差分析示弦斜度性别差异有极显著性（ Ｆ＝ ７．７９１４, Ｐ＜ ０．０１）。④结论　用弦斜度代替补偿曲线曲度是可行的。     

长途汽车司机有关艾滋病知识和态度的调查

①目的　调查长途汽车司机有关艾滋病（ Ａ Ｉ Ｄ Ｓ）的知识及对 Ａ Ｉ Ｄ Ｓ的态度,为进一步在该人群中开展艾滋病知识的宣传教育、制订有关预防措施提供依据。②方法　对青岛市 ３ 个长途汽车运输公司以单纯随机抽样方法抽取７４ 名进行调查,调查表采用匿名自填方式。③结果　大多数调查对象对艾滋病的病原体、传播途径、临床表现及潜伏期病人的危险性认识不足,而对艾滋病的有关知识感兴趣,并希望通过各种途径加以了解。④结论　长途汽车司机对有关艾滋病的知识了解较少,应加强对该人群有关艾滋病知识的宣传教育。     

海南省流动儿童计划免疫现况分析

为更好地了解流动儿童计划免疫管理现况,１９９７年海南省组织了专题调查,发现流动儿童以县内流动为主,流动儿童上卡率为７６．６％,五苗接种率分别为卡介苗６９．４％,脊灰糖丸６５．１％,百白破６３．６％,麻疹５９．９％,ＨＢＶ５６．９％,均远未达到目标要求,脊达抗体ＧＭＴ流动儿童为１：１５３．２０,常住儿童为１：２４３．６１,两者有显著性差异,这表明,加强流动儿垢计划免疫管理,最今后计免工作的重点和难点
