眼内异物合并外伤性白内障的联合手术治疗：附88例分析

眼内异物合并外伤性白内障是眼外伤常见的致盲原因之一,各地报告的致盲率为20%～48.9%。本文对88例眼内异物合并外伤性白内障患者采用联合手术治疗,收到较好疗效,术前视力0.05以下占85.2%,术后矫正视力0.05以下占27.3%,矫正视力0.06～1.5占73.7%,其中矫正视力0.6～1.5者占22.8%。根据异物的性质、在眼内部位和晶体损伤情况选择不同的手术方式一次联合手术摘出异物和白内障,术后采用中西药配合治疗。联合手术可提高疗效,减少术后并发症.减少手术次数,减轻病人的痛苦,缩短病程,减少医疗费用.眼科学报1993;9:216—218.     

中药空气消毒液消毒作用的实验研究

作者通过大量的基础实验和临床现场实验研究,成功研制了中药空气消毒液。研究结果证明:本品具有抗细菌,抗甲型、乙型流感病毒及单纯疱疹病毒的作角。该药液对以金黄色葡萄球菌为代表的G~+菌,以大肠杆菌、绿脓杆菌为代表的G~-菌的最小抑菌浓度为5％,最小灭菌浓度为20％,最短灭菌时间为5min。毒理试验证明长期使用此药液无毒副作用。本品在常温下保存性能稳定;对日常用品无损伤现象。临床试验结果证明本品喷雾空气消毒作用与常规紫外线照射法、过氧乙酸喷雾法基本相同。效果满意。     

Are there any successful men from criminogenic backgrounds?

In the Cambridge Study in Delinquent Development, a prospective longitudinal survey of 411 London males, a vulnerable group of 63 boys from criminogenic backgrounds was defined on the basis of the best nonbehavioral predictors of delinquency at age 8-10 (low family income, large family size, convicted parents, low intelligence, and poor parental child-rearing behavior). These males were followed up to age 32, and the more successful men were defined according to criteria such as the absence of convictions and of other deviant behavior, good relationships with wives and children, and good accommodation and employment histories. Hence, "success" here refers to satisfactory social adjustment. The more successful men were those who had been neurotic at age 10, those who had few or no friends at age 8, those without convicted parents or behavior problem siblings, those with mothers who had a high opinion of their sons, and those who did not spend their leisure time with their fathers. At age 8-10 they were already better behaved and less daring than those later judged as the unsuccessful men. There was some tendency for shyness to act as a protective factor against delinquency for non-aggressive boys but as an aggravating factor for aggressive boys.     

宫颈粘液过氧化物酶在月经周期中的变化规律

本文对29例月经周期正常妇女的宫颈粘液过氧化物酶进行了30个周期的研究。在月经周期不同时间测定宫颈粘液过氧化物酶(CMPx)活性及血清促黄体生成素(LH)、雌二醇(E_2)和孕酮(P)。结果表明:在排卵前三天酶活性明显下降,至排卵后一天开始上升。卵泡期,酶活性与E_2呈负相关(r=-0.67);黄体期,酶活性与P呈正相关(r=0.79)。本研究提示:1.CMPx在排卵周期具有特定的变化规律,其变化受体内激素水平影响,可作为预告排卵的指标。2.如简化测定方法,可为自然避孕提供新途径。     

“90增血剂”对特发性血小板减少性紫裥患者的T细胞亚群的作用

作者根据现代免疫学观点,自1989年起采用自制中药“90增血剂”治疗ITP46例。期间,应用间接免疫荧光技术检测了患者外周血T淋巴细胞亚群,结果表明病例组全T细胞(CD_3)、T辅助/诱导细胞(CD_4)降低,T抑制/细胞毒细胞(CD_8)增高,CD_4/CD_8比值明显降低。治疗后,患者T亚群恢复常态,血小板数上升,骨髓产板型巨核细胞数增加,临床总有效率达91.2%,明显优于激素组(71.4%)。提示中药具有显著的疗效和良好的免疫调节作用。同时,动态观察ITP患者T细胞亚群的变化,对帮助临床判断治疗反应和预后有很大意义。     

CLINICOPATHOLOGICAL CONFERENCE A 51-YEAR-OLD MAN WITH PALPITAT10N, SHORT BREATH, CYANOSIS AND SUFFOCATION

A 51-year-old man was admitted to our hospital on January 23, 1985 because of pal- pitation and short breath for 40 years. He was well until 7 years of age. Then he devel- oped symptoms ofpalpitation and shortbreath with cyanosisafter exercises. Relief of the symptoms would be achieved by squat- ting for a while or taking a few minutes' rest. Later, his growth was retarded. In 1960 he developed clubbing fingers. In 1965 when hospitalized for tonsillectomy, he was sus- pected of having "congenital heart disease" with ventricular septal defect, stenosis of the pulmonary artery and Eisenmengeris syndrome in question. In 1966, cardiac catheterization was performed, showing that the partial pressure of blood oxygen was l.85 vol%, higher in the right ventricle than in the left auricle. This means there exists a left to right shunt and the magnitude of shunt is 24.0% of the pulmonary circulation. The blood oxygen saturation in the f'emoral artery is a little bit low (93.5%). The hemoglubin concentration is (180g/l). Bilateral shunt could not be excluded.Since August 1969, he began to be very often troubled by nocturnal dyspnea, cough and chest distress. These symptoms could be abated by the treatment of aminophytlline. In 1976, ultrason- ocardiography revealed ventricular septal de- fect and aortic insufficiency. In May 1984. he had high fever for several days and was sus- pected of having "bacterial endocarditisu. The fever subsided with antibiotic therapy for a few db.ys. Twenty days before this hosptalization he had chest distress, short breath, palpitation, cyanosis, nocturnal dyspnea and paroxysmal precordial pain af- ter getting cold.     

Button bolsters in dermatologic surgery

Ordinary plastic buttons may be used as bolster devices to relieve tension across wounds. This article describes the method of placement of those "button bolsters" and suggests two methods of closing the wound once they are in place. This simple technique is easily mastered and gives additional wound closure security in the initial phase of wound healing.
