直肠内微波透热法治疗前列腺增生症

报告直肠内微波透热治疗前列腺增生症55例,显效和有效占80%。经3月～10月随访,63.6%疗效如初。治疗前后前列腺腺体体积对比,85.5%缩小,而药物随机对照组仅9%缩小。此法无痛苦、无损伤、无明显副作用、方便易行且疗效较好,值得进一步研究、推广。     

视网膜脱离伴发青光眼

本文报道９７例（１０３眼）视网膜脱离伴发青光眼，其中原已有明确诊断青光眼病史、抗青光眼手术史的视网膜脱离２１例（２５眼）。视网膜脱离合并葡萄膜炎继发青光眼３例。视网膜脱离术后继发青光眼７０例（７２眼）。视网膜脱离与青光眼交替发病型３例。并重点讨论了各类型的临床特点，发病机理及治疗。     

食管霉菌病1例报告

患者，女，24岁。自述食管内异物感及吞咽不畅，夜间加重，食管内似有活动性异物上行至咽喉部。时常出现恶心，严重时胸骨后疼痛及吞咽阻挡感。曾在外院诊断为慢性食管炎及咽炎，经用抗生素治疗未见好转。即来我院就诊。体检：发育营养一般，体温、脉搏、血压正常，全身浅表淋巴结不大，咽及口腔粘膜血管，胸腹部及四肢检查均未见异常。实验室检查无异常。X线检查：钡餐造影示食管中下段不规则充盈缺损，并有轻度狭窄区食管粘膜呈虫蚀状或网络状改变。     

铁骨晶对大鼠钙代谢、骨密度的影响及临床观察

本实验以铁骨晶（多肽钙），进口脱脂奶粉，活性钙冲剂，贝壳钙为钙源添加于大鼠正常饲料中。观察结果表明：上述４组钙的吸收率分别为６４．４％，６９．１％，５９．９％，５１．６％；钙的储留率分别为８９．８％，９３．３％，８５．２％，７９．０％；钙的存留率分别为４３．６％，４９．０％，３２．４％，２６．８％；股骨指数分别为７．０２×１０（－３），６．４３×１０（－３），６．８４×１０（－３）。６．８８×１０（－３）；折断力（牛顿）分别为６０．５４±１２．５５，４６．８１±９．３２，４３．２６±１６．６２，３８．２４±１０．７９。同时以铁骨晶为钙源对７０例（５～６岁）儿童进行了血清Ｃａ，Ｆｅ，Ｚｎ，Ｈｂ及生长发育的检测。铁骨晶组的身高，体重，胸围分别比对照组增加。铁骨晶组血清Ｃａ，Ｆｅ，Ｚｎ，Ｈｂ也均有较好的改善。这表明铁骨晶具有较好的促进钙吸收利用作用，同时能增加骨强度作用。     

IS THE SEVERITY OF OSTEOSCLEROSIS OF FLUOROSIS PROPORTIONAL TO THE DOSE OF FLUORIDE INTAKE?

Histomorphometric study was made on a series of sections of undecalcified epiphyseal femoral specimens from rats with experimental fluorosis. The results revealed osteosclerosis in Group A (5 ppm) being more severe than that in Group B (25 ppm) With the increase of fluoride dose, the parameters fell down instead of increased in parallel. There is seemingly a threshold over which osteosclerosis in fluorosis becomes less severe. In contrast to Bely's conclusion the authors proposed that, fluoride toxi- city, besides decreasing the number of osteoblasts, may also activate the osteoblasts. The number of osteoblasts may be increased with relative lower dose of fluoride also. The net outcome is the in crement in bone volume. When toxic dose of fluoride is higher enough (higher than the proposed threshold), however, the number of osteoblasts and its activity are inhibited. So are the osteocytes. This interpretation may be the cytological basis for osteosclerosis in the experimental fluorosis.     

慢性乙型肝炎中医辨证研究的方法和思路

慢性乙型肝炎中医证型繁杂、辨证标准不统一，临床不易掌握及推广。建立客观的标准化中医辨证体系有利于临床实践及研究，其方法是在中医理论的基础上，首先实现证候的规范化及临床病例采集的规范化，再进行聚类分析、判别分析及多元回归分析，最终实现慢性乙型肝炎中医辨证的标准化。
