拜安捷TM血糖监测仪免调码技术的试验分析

血糖仪的调码是指不同批号的试纸由于生产条件的不同而产生的批间差异，因此，在使用不同批号的试纸测试血糖时，需要血糖仪根据试纸上的密码校准批间差异。目前市场上的血糖仪大多在更换试纸时必须先手动调整血糖仪的代码或手动插入试纸盒内专用的代码卡。     

患丙型肝炎的肝移植病人的免疫抑制及转归（下）

在特异性免疫抑制剂对丙型肝炎移植病人长期结果的影响方面，存在一些疑惑，使用皮质醇治疗急性细胞排斥对感染HCV的接受是有害的。多年前，Kings学院医院Ed Gane和同事表示皮质醇片剂与血清中HCVRNA浓度增加4到100倍有关。较高的HCV RNA水平也与复发性肝炎的组织学严重程度增加有关。他们也表示皮质醇片剂与急性肝炎和较早时间复发的频率增加有关。     

Q热（下）

直接接触动物 多数Q热感染是由于在动物分娩或屠宰反刍动物的时候吸入了被污染的悬浮颗粒造成的。上述事件造成环境污染可以持续数月到数年，因此吸入灰尘也可能致病。牛、绵羊、山羊是感染人类的主要传染源。     

ANGURAR BLEPHARITIS IN WELL KNOWN CLINJ OF RIBOFLAVIN ARIBOFLAVINOSIS - A CAL . MANIFESTATION DEFICIENCY

Sebrell in 1938 (i)五rst suspected that pellagra might be a manifestation of multiple deficiency in which ribofiavin .might play a role. Experiments carrie.d out by him and Butler in the ''same year showed that diets low in ribofiavin content would produce a clinical syndrome, which we now know to'' be char- acteristic of ribofiaviri. deficiency. The w~rk of these authors w.as later confirmed by workers in all partbs of the world. Spies (2)i Sydenstricker (3), Viakil（二）, Gopalan (5), Hou (6), (7), etc. a:re important contributors. The disease has been reported in tIhe United States of America,''England, Africa, India, M.alaya and is quite common in China, especially among soldiers, students, coolies, refugees and prisoners. .     

ACUTE CECO-COLIC lNTUSSUSCEPTION IN ADULT CAUSED BY TRICHURIS TRICHIURiY INFESTATION REPORT OF.A CASE

InX.rssusception .of intestine occurs most frequently in children under two years of age,1n which no apparent excitingi cause is known to be present in the lai''gye ma.jorities (1). Rarely, it may occur in adults as a result of some sorts of anatomioal or pathological changes in the wall of the intestine such as tumor grrowths, diverticula, chronic granulomata, chronic inflamrnations, etc* Intestinal intussusception of parasitic origin has beeri occasionally recorded in the literature (2,S)t of which;-schistosomiasis was responsible for most of the oases.'' Other kinds of intestinal parasites may also produce a similar lesion but they are relatively rar4e     

股骨干骨折--扩髓和不扩髓髓内钉比较

治疗股骨干骨折，采用不扩髓髓内钉比扩髓髓内钉手术时间明显缩短，而且失血也少。但是，扩髓钉的骨愈合更快，延迟愈合更少。两者都没有显著增加包括肺损害等其它并发症的风险。功能结果不能确定。     

自身免疫性肝炎-进化的概念（下）

9．细胞因子 1型和2型细胞因子组成了免疫调节网络，其以繁多的作用和广泛的交叉调节功能为特点。细胞因子网络影响着自身免疫性肝炎的发生、临床表现和结果。 在1型和2型自身免疫性肝炎的儿童中已经描述了不同的细胞因子模式。2型细胞因子的应答可使自身免疫性肝炎区别于慢性病毒性肝炎。IL-2和IL-4一般较少，1型自身免疫性肝炎病人的成人中其血清浓度低于正常人。1型细胞因子在肝脏中炎症活动期间占优势。2型细胞因子在缓解期的循环系统中占优势。这些结果表明在疾病活动期细胞因子模式的变化，或是免疫反应的原因，或是其结果。     

麻风的研究问题

麻风的研究问题Ｊ．Ｇｒｏｓｓｅｔ因为ＷＨＯ的ＭＤＴ治疗麻风非常有效，有人正在鼓吹对麻风已不再需要研究了。可以认为，ＭＤＴ已证明很有效，只要推广应用便足以在２０００年时达到将麻风做为公共卫生问题加以解决的目标。不过，这种想法有失于太简单。首先，科学知识...
