淫羊藿、巴戟天中药提取物对恒河猴M0、M1型单核衍生巨噬细胞基因表达的影响

【目的】探讨中药淫羊藿、巴戟天提取物(中药注射液喘可治的组成)对恒河猴单核衍生的巨噬细胞在未极化(M0)、M1极化条件下基因表达的影响,分析其可能的免疫调节的作用机制。【方法】采用密度梯度离心法分离中国恒河猴外周血单个核细胞(PBMCs),采用贴壁法纯化出单核细胞,并以粒细胞巨噬细胞集落刺激因子(GM-CSF)刺激5 d以使单核细胞分化成巨噬细胞;然后不加入极化因子(M0)或以干扰素γ(IFN-γ,继续培养2 d)诱导巨噬细胞极化为M1表型,同时分别加入淫羊藿、巴戟天提取物进行干预;然后提取m RNA并逆转录后,采用实时荧光定量PCR检测CCR5、CD4、CTLA-4、Fox P3、IDO、IL-10、TGF-β等基因表达量。【结果】与空白对照组比较,加入巴戟天提取物培养的M0巨噬细胞基因表达上调不明显;经淫羊藿提取物培养的M0巨噬细胞,CCR5基因表达量上调4.21倍,TGF-β上调7.66倍,Fox P3、IL-10轻度上调,而CD4、CTLA-4、IDO等基因表达改变倍数无明显变化。经巴戟天提取物刺激的M1型巨噬细胞,CTLA-4基因表达量上调3.22倍,Fox P3上调3.69倍,CCR5、CD4、IL-10、IDO基因改变倍数均无明显变化,TGF-β未测出;而由淫羊藿提取物刺激的M1型巨噬细胞,IL-10的表达量上调11.83倍,Fox P3上调4.55倍,IDO、CCR5、CD4、CTLA-4基因改变倍数无明显变化,TGF-β未测出。【结论】巴戟天和淫羊藿提取物培养能够上调M1型巨噬细胞IL-10、Fox P3、CTLA-4等抑炎基因表达,淫羊藿提取物能够上调M0巨噬细胞CCR5和TGF-β等基因表达,促进病原体清除和组织修复,从而发挥多效免疫调节作用。

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. .

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。
