Respiratory Sinus Arrhythmia in Cluster Headache Syndrome

SYNOPSIS
Respiratory sinus arrhythmia is regarded as indicative of cardiac vagal integrity. A ratio of the longest R-R interval to the shortest R-R interval during deep breathing test (E:I ratio) was calculated in controls (n=49), cluster headache (n=33) and CPH (n=4) patients, E:I ratio decreased with age but was not dependent upon sex or upon smoking habits. Furthermore, there were no significant differences as regards E:I ratio between cluster headache patients in and outside a bout, or between patients with right-sided and left-sided headache. However, the E:I ratio was found to be significantly lower in the cluster headache group as such, when compared with controls, but the number of patients disclosing pathological or borderline results was small, 2 and 2, respectively. This may indicate that a putative vagal dysfunction in cluster headache is usually less marked than in patients with e.g. diabetic autonomic neuropathy. Significant attack-related change in the E:I ratio were detected in all individual patients though these changes were not of a uniform nature from individual to individual. E:I ratios were rather high in 3 out of 4 CPH patients examined. However, the number of patients in this group is too small to allow definite statements about the difference between CPH end cluster headache with regard to E:I ratios. There was no significant difference between E:I ratios outside and during a mild, short, mechanically precipitated attack in a single CPH patient.     

无张力疝修补术后顽固性疼痛原因和对策

目的 探讨无张力疝修补术后的顽固性疼痛病因及预防治疗。方法 将同期无张力疝修补术与传统的腹股沟疝修补方法进行比较。结果 无张力疝修补术后的顽固性疼痛率为9．02％(12／133)，传统的腹股沟疝修补方法疼痛率为8．61％(18／209)。无张力疝修补与传统的腹股沟疝修补相比，术后顽固性疼痛的发生率差异无显著性(P＞0．05)。结论 无张力疝修补并不一定减少传统的腹股沟疝修补术后顽固性疼痛，手术规范操作是预防的关键，治疗应先保守治疗，无效再考虑手术治疗。     

金珠滴眼液治疗慢性结膜炎的临床研究

目的　探讨金珠滴眼液治疗慢性结膜炎的疗效。方法　将慢性结膜炎患者 36例 6 8眼随机分为2组 ,每组 34眼 ,实验组用 7.8%金珠滴眼液点眼治疗 ,对照组用 0 .2 5 %氯霉素点眼治疗。结果　金珠滴眼液1、2、4周疗效的综合分值判定均与对照组有显著差异 (P <0 .0 5 ) ,且无局部刺激性。结论　金珠滴眼液对慢性结膜炎有明显的治疗作用 ,可望为临床常见多发的慢性结膜炎患者消除或缓解症状     

病理性损伤因素对肾小管上皮细胞表型转化的影响

目的 :观察低血清、高糖、高蛋白刺激下肾小管上皮细胞向间叶性细胞的表型转化 ,探讨损伤的肾小管上皮细胞在肾小管间质纤维化中的作用。方法 :以体外培养的人近端肾小管上皮细胞为对象 ,分别用含低血清(0 .2mol·L-1小牛血清 )、高葡萄糖 (4.5 g·L-1)、高白蛋白 (15 g·L-1)的培养液培养 7d ,透射电镜检测细胞形态变化 ;免疫组化和Westernblot检测细胞表型改变 ,包括CK、Vimentin、α SMA、Ⅰ和Ⅲ型胶原 ,原位杂交检测Ⅰ型胶原mRNA表达 ,同时检测细胞TGFβ1蛋白表达。 结果 :低血清、高糖、高蛋白直接刺激下 ,肾小管上皮细胞出现明显形态学改变 ,包括细胞变为长梭形 ;透射电镜下细胞内线粒体明显减少 ,粗面内质网明显增加 ,并出现actin样微丝。免疫组化染色和Westernblot显示CK表达明显减弱 ,Vimentin、Ⅰ、Ⅲ型胶原、α SMA和TGFβ1表达增强。原位杂交显示Ⅰ型胶原mRNA表达增强。结论 :低血清、高糖、高蛋白可直接引起人近端肾小管上皮细胞TGFβ1表达增加 ,并发生向间叶性细胞的表型转化     

慢性阻塞性肺疾病患者家庭支持与自我概念的相关性研究

目的 探讨慢性阻塞性肺疾病(慢阻肺)患者的家庭支持与自我概念的关系。方法 用方便抽样法选取108位慢阻肺患者，应用修订的个人资源问卷、自我概念量表和一般资料问卷分别测定其家庭支持、自我概念水平和一般资料。结果 该组患者家庭支持程度为中到高度，自我概念中度积极；家庭支持与总的自我概念呈中度正相关，与自我概念中的体感、自我一致性、理想自我及道德一伦理一精神自我有显著相关．与体象无关。结论 慢阻肺患者的家庭支持水平越高，其自我概念越积极。     

高压氧在治疗脊髓损伤伴截瘫及肢体慢性溃疡中的应用

本文报告了用高压氧治疗脊髓损伤伴截瘫患者１２例，肢体慢性溃疡８例。将患者置于２个大气压的单人氧舱内，每次９０ｍｉｎ。前者疗程为１周，每日２次。后者疗程为２周，每日１次。治疗结果：脊髓损伤伴截瘫患者中８例有明显而有意义的功能恢复，占６６．６％。慢性溃疡患者中有３例愈合，４例好转，有效率为８５％。作者认为：早期使用高压氧是治疗急性截瘫，尤其是不完全性截瘫的一种安全有效的方法。高压氧治疗可加速慢性溃疡创面的愈合，但不能取代溃疡面的局部处理。     

Primary malignant lymphoma of the rectum with distant metastasis to the stomach: Report of a case

Primary extranodal malignant lymphoma frequently occurs in the gastrointestinal tract; however, it is rarely encountered in the rectum. We report herein the case of an 85-year-old man who underwent abdominoperineal resection for primary malignant lymphoma of the rectum, and 1 year later, developed hematemesis caused by gastric metastasis. To our knowledge this is the first case report of such distant metastasis developing from malignant lymphoma of the rectum.
