AN EEG STUDY OF 120 EPILEPTIC FAMILIES

To study the epilepsy heredity, routine EEG tracings of 120 epileptic families and 57 normal control families were carried out. The results suggest that epilepsy shows an obvious tendency to be inherited.     

甾体避孕药不增加血栓栓塞性疾病危险(病例对照研究)

本文采用1:3病例对照研究方法,对甾体避孕药的使用与血栓栓塞性疾病(急性心肌梗塞、脑栓塞、脑血栓形成和深静脉血栓形成)间的关联进行多因素分析。结果提示在我国广泛应用的甾体避孕药(主要为国产Ⅰ号避孕药)并不增加血栓栓塞性疾病的危险性。用药和停药时间的长短与血栓栓塞性疾病的发生无关,并与高血压病之间亦不存在协同作用。     

钙剂加维生素D治疗对糖尿病患者钙代谢的影响

本文报道NIDDM患者在常规治疗的基础上加用钙剂和维生素D治疗后的钙代谢变化。糖尿病患者单纯用常规治疗控制血糖后,负钙平衡不能完全纠正,而加用钙剂和维生素D治疗后,负钙平衡能完全纠正,并且高于正常对照组平衡值(P<0.01)。说明钙剂加维生素D治疗对糖尿病性骨质疏松是有益的。

局部注射IL-12治疗小鼠皮下肿瘤的实验研究

目的:探讨局部应用白细胞介素-12(IL-12)对于小鼠皮下肿瘤的治疗作用.方法:小鼠右侧腹部皮下注射2x105 个Panc-02细胞建立皮下肿瘤模型.皮下肿瘤被检测24d,通过测量的皮下肿瘤的两个直径以计算出肿瘤大小(mm2).分为IL-12治疗组和对照组,每组6只小鼠.从第3～7天,IL-2治疗组,每天在肿瘤周围注射0.1 μg IL-12,对照组同时同部注射同量平衡盐水.结果:与对照组相比,IL-12治疗组从第7天开始Panc-02肿瘤的生长出现受到抑制.第10天,IL-12治疗组[(13.8±8.7) mm2]与对照组[(36.4±8.5) mm2],(P＜0.05)之间的差异有统计学意义(P＜0.05).第24天,两组之间的差异更加明显[(66.5±50.4) mm2 VS (264.4±46.4 )mm2, P＜0.01].结论:肿瘤周围注射IL-12明显抑制Panc-02皮下肿瘤的生长,为应用于临床肿瘤治疗提供可能性.     

Information Fusing Recognition of Traditional Chinese Medicine （TCM） Pulse State Based on Stochastic Fuzzy Neural Network

Based on the fuzzy characteristic of the pulse state and syndromes differentiation thinking mode of TCM, an information fusing recognition method of pulse states based on SFNN （Stochastic Fuzzy Neural Network） is presented in this paper. With the learning ability in parameters and structure, SFNN fuses the measurement information of three pulse-state sensors distributed in Cun, Guan, and Chi location of body for the pulse state recognition. The experimental results show that the percentage of correct recognition with new method is higher than that by single-data recognition one, with fewer off-line train numbers.

Trehalose protects against ocular surface disorders in experimental murine dry eye through suppression of apoptosis

The disaccharide trehalose is a key element involved in anhydrobiosis (the capability of surviving almost complete dehydration) in many organisms. Its presence also confers resistance to desiccation and high osmolarity in bacterial and human cells by protecting proteins and membranes from denaturation. The present study used a novel murine dry eye model induced by controlled low-humidity air velocity to determine whether topically applied trehalose could heal ocular surface epithelial disorders caused by ocular surface desiccation. In addition, the efficacy of 87.6 mM trehalose eyedrops was compared with that of 20% serum, the efficacy of which has been well documented. Mice ocular surface epithelial disorders were induced by exposure of murine eyes to continuous controlled low-humidity air velocity in an intelligently controlled environmental system (ICES) for 21 days, which accelerated the tear evaporation. The mice were then randomized into three groups: the control group received PBS (0.01M) treatment; a second group received 87.6 mM trehalose eyedrops treatment; and the third group received mice serum eyedrops treatment. Each treatment was administered as a 10 μl dose every 6 h for 14 days. The resultant changes in corneal barrier function and histopathologic examination of cornea and conjunctiva were analyzed and the level of apoptosis on the ocular surface was assessed using active caspase-3. After 14 days of treatment, the corneal fluorescein staining area, the ruffling and desquamating cells on the apical corneal epithelium, as well as the apoptotic cells on ocular surface epithelium had significantly reduced in eyes treated with trehalose compared with those treated with serum and PBS. In contrast, after 14 days of treatment, improvements in the thickness of the corneal epithelium, the squamous metaplasia in conjunctival epithelium and the number of goblet cells of the conjunctiva were less marked in eyes treated with trehalose compared with serum. These results demonstrated that trehalose could improve the appearance of ocular surface epithelial disorders due to desiccation through suppression of apoptosis. Trehalose produces some of the same responses as serum upon topical application and can maintain corneal health.
