The indication of surgical treatment of cerebellar hemorrhage]

61 patients with cerebellar hemorrhage were studied. The age at onset ranged from 15 to 84 years with a mean of 57.4 years. 49 cases were treated conservatively and 12 surgically and the mortality rates of the two groups were 32.5% and 25% respectively. Based on this study, it is suggested that the clinical and CT indications of surgical treatment of hematoma are as follows; Severe disturbance of consciousness; Bilateral eyeball fixation; Volume of hematoma over 10 ml; Size of hematoma over 4 cm in diameter; Marked acute obstructive hydrocephalus; Compression of cisterna ambieus and quadrigeminus.     

带血管蒂岛状筋膜瓣移植治疗晚期类风湿性髋关节炎

目的：阐明带血管蒂岛状筋膜瓣移植治疗晚期类风湿性髋关节炎的疗效。材料和方法：对４２例４８髋晚期类风湿性髋关节炎病人采用以旋股外侧血管降支为蒂的股前外侧筋膜瓣移植行患髋成形术。结果：术后随访４～１０．５年，平均４．５年，髋关节活动范围术前平均１６．５°，术后２２８．６°，按照Ｃｈａｒｎｌｅｙ和吴之康人工髋关节置换术后的疗效评定标准，优良２９髋、很好１３髋、好６髋，尚可、差、很差无。结论：患者年龄在１５～４０岁之间为合适的治疗年龄。与人工髋关节置换术相比，本方法对髋关节正常结构破坏小；一旦手术失败仍可选用其它治疗方法弥补；且并发症少、费用低、远期效果好。     

视觉近点测定修布和验布作业视疲劳的初步探讨

应用视觉近点测定评价纺织厂不同作业工人的视疲劳。检查了32名修布工人和38名验布工人。同一工厂的33名保育员作对照组。结果表明:视觉近点的测定指标比调查受试者主诉的眼视觉症状更为敏感。修布和验布组在工作后,作业者的视觉近点比上班前明显变远,但时照蛆工作前后无明显变化。三组视觉近点比较,发现修布和验布组视觉近点的变化。提示由修布和验布作业引起的视觉疲劳,可以通过测定视觉近点来进行评价。

Relationship among dosages of aminophylline, plasma levels of theophylline and variation of pulmonary arterial pressure]

The relationship among the dosages of aminophylline, plasma levels of theophylline and variations of mean pulmonary arterial pressure (mPAP) in 72 patients with COPD was investigated. The results showed that after a different loading dosage of aminophylline (6 mg/kg, 5 mg/kg and 4 mg/kg) was administered by intravenous injection, mPAP in the 6 mg/kg group was decreased more significantly (P less than 0.01) than that in the 4 mg/kg group. In the 6 mg/kg group, the decreased mPAP period sustained for 120 min, which was longer than that in the other 2 groups. The plasma levels of theophylline in the 6 mg/kg group of patients 30 to 120 min after loading dose injected were 115.54-79.04 mumol/L, which were higher than that in the others. Within the 120 min period of observation after the drug was administered no patients in any of these groups showed severe untoward effects. According to the results of this experiment, we suggest that the 6 mg/kg as a loading dose should be advised for the treatment of pulmonary hypertension in COPD. The optimum time to give the maintenance dosage should be set within 2 h after the loading dose. It is necessary to monitor the plasma levels of theophylline while aminophylline is administered, so that optimal therapeutic effects could be achieved without side effects.     

重度创伤患者外周血单个核细胞HLA-DR的表达与创伤后免疫功能障碍的关系

为了探讨创伤后机体细胞免疫、体液免疫及红细胞免疫功能障碍与外周血单个核细胞ＨＬＡ－ＤＲ表达率之间的关系，本文选择了３０例重度复合伤病人。在住院治疗期间，连续观察了患者受伤当日、伤后第３、１０、２０ｄ及出院前一天外周血单个核细胞ＨＬＡＤＲ表达率的变化及其与细胞免疫、体液免疫及红细胞免疫功能状况之间的相关性，发现创伤病人自受伤当日至出院前外周血单个核细胞膜上ＨＬＡ－ＤＲ表达率的变化无统计学意义（Ｐ＞０．０５），提示创伤后免疫功能障碍不是由于外周血单个核细胞ＨＬＡ－ＤＲ表达异常所致。     

结直肠癌中雄激素受体及其与临床病理学特征关系的研究

应用放射性配基结合分析法，检测了４０例结直肠癌及部分癌旁正常粘膜组织中的雄激素受体（ＡｎｄｒｏｇｅｎＲｅｃｅｐｔｏｒ，ＡＲ），同时分析了ＡＲ水平与临床病理学变化的关系。证实结直肠癌ＡＲ数目（３３．７±２３．３ｆｍｏｌ／ｍｇ蛋白）明显低于癌旁５ｃｍ以外粘膜（５３．９±３２．４ｆｍｏｌ／ｍｇ蛋白），Ｐ＜０．０１，而其亲和力则无变化；结直肠癌时ＡＲ数目变化与女性、直肠癌、高分化癌及早期癌关系密切。提示ＡＲ与结直肠癌关系密切，本实验为临床上结直肠癌的诊断及内分泌治疗提供了初步资料。

Exogenous advanced glycosylation end products induce diabetes-like vascular dysfunction in normal rats: a factor in diabetic retinopathy

BACKGROUND. Diabetic retinopathy has been shown to be directly associated with the degree and duration of hyperglycemia, and advanced glycosylation end products (AGEs) have been implicated in this pathological process. The purpose of the experiments reported here was to study the effect of AGE deposition on retinal vascular damage which leads to diabetic retinopathy. METHODS. Intravenous injection of exogenous AGEs was used to treat wild-type non-diabetic Sprague-Dawley rats. One of the two retinal slides from each animal was treated using immunohistochemical staining to label retinal vascular AGE deposition, the other H&E staining for counting of capillary pericytes. The results were compared with the findings in untreated wild-type and diabetic controls and in rats treated with unmodified rat serum albumin (RSA). RESULTS. After 2 weeks of continuous treatment, AGEs were identified in the retinal vascular tissue of the AGE-RSA-injected group. The average number of retinal capillary pericytes per 10x100 microscope power field was 4.313+/-0.34 (mean +/- SD) in the AGE-RSA-injected group, compared with 5.798+/-0.481 in the control group ( P<0.01). CONCLUSION. These experiments demonstrate that AGEs, independent of other metabolic factors, can induce vascular change resembling that of diabetic retinopathy.     

Effects ofTripterygium hypoglaucum (Lévl.) Hutch on male fertility

Tripterygium hypoglaucum (Lévl.) Hutch (TH) is a perennial used in Chinese traditional medicine for the treatment of rheumatoid arthritis and various skin disorders. One study showed that daily oral doses of TH significantly reduced the fertility of male rats without apparent toxicity. The effects of daily oral doses of TH on the fertility of men taking it for the treatment of rheumatoid arthritis were evaluated. Sperm concentration, motility and motility grade all were significantly reduced in the 13 men taking TH compared to 11 untreated controls. TH therapy did not affect testosterone, FSH, LH levels, and its antifertility effects appeared to be reversible.

Resumen Triperygium hypoglaucum (Lévl.) Hutch (TH) es una perenne usada en la medicina tradicional china para el tratamiento de artritis reumatoidea y de varios desórdenes de la piel. Un estudio demostró que orales diarias de TH reducían significativamente la fertilidad en ratas macho, sin toxicidad aparente. Se evaluaron los efectos de dosis diarias orales de TH en la fertilidad de hombres que le tomaban para el tratamiento de la artritis reumatoidea. La concentración de espermatozoides, la motilidad y el grado de motilidad, se encontraron significativamente reducidos en los 13 hombres tomando TH comparados con 11 controles no tratados. La terapia con TH no afectó los niveles de testosterona, FSH y LH y sus efectos antifertilidad parecían ser reversibles.

Resumé LeTriperygium hypoglaucum Hutch (TH) est communément utilisé en médecine traditionnelle chinoise pour le traitement de la polyarthrite chronique évolutive (PCE) et de divers troubles cutanés. Une étude a montré que l'administation quotidienne de doses orales de TH réduisait considérablement la fécondité de rats mâles sans provoquer de toxicité apparente. On a évalué les effets de doses quotidiennes administrées par voie orale sur la fécondité d'hommes atteints de PCE et traités au TH. La concentration, la motilité et le degré de motilité du sperme avaient significativement diminué chez 13 hommes traités au TH par comparaison avec 11 témoins non traités. Le traitement au TH n'a eu aucun effet sur les niveaux de testostérone, FSH et LH et ses effets anti-fécondants semblent être réversibles.
