武汉市健康人群乙型肝炎抗体水平监测

目的了解目标人群乙型肝炎免疫水平,评价免疫规划的有效性,为疾病预测和预防控制策略提供相关依据。方法采取分层随机抽样原则,在武汉市硚口区和江夏区各抽取480人,共采集960名监测对象的血清,采用SPSS 20. 0软件进行统计分析。结果健康人群8个年龄组乙型肝炎表面抗原(HBsAg)阳性率为3. 23%,乙型肝炎病毒表面抗体(HBsAb)阳性率为72. 19%;城乡、性别人群组HBsAg阳性率差异无统计学意义,年龄组间HBsAg阳性率差异有统计学意义(χ~2=20. 218,P 0. 01),职业组HBsAg阳性率差异有统计学意义(χ~2=19. 055,P 0. 05),文化程度组HBsAg阳性率差异有统计学意义(χ~2=14. 18,P 0. 05);城乡、性别、职业组HBsAb阳性率差异无统计学意义,文化程度组HBsAb阳性率差异不大,阳性率在67. 79%～76. 19%之间,年龄组间HBsAb阳性率差异有统计学意义(χ~2=66. 596,P 0. 01)。结论武汉市健康人群HBsAb阳性率明显高于2006年全国乙肝血清调查结果;乙肝疫苗接种是预防乙肝的重要常规免疫管理措施,今后的工作需要进一步提高疫苗接种率,特别是提高24h内新生儿首针及时接种率。     

以眶尖综合征为首发临床表现的鼻咽癌一例

患者,男,60岁,因“头痛20余天、右眼视力下降5 d及睁眼困难3 d”于2019年3月20日就诊于暨南大学附属第一医院眼科门诊。患者多年前诊断为鼻窦炎,长期头痛伴鼻塞未行治疗。此次就诊前20 d无明显诱因出现右侧颞部头痛,疼痛持续无缓解,1周前于暨南大学附属第一医院耳鼻喉科就诊行鼻咽部肿物活检,病理结果示:镜下见小片鳞状上皮及少量炎性渗出物和凝血块。5 d前突然出现右眼视力下降,3 d前右眼出现睁眼困难,未予治疗。     

谷氨酰胺在危重病患者中的应用

目的探讨危重病患者中早期经静脉应用谷氨酰胺（glutamine，Gl）的临床价值。方法42例患者随机分成两组（对照组和Gln组），Gln组进行Gln治疗（100mL／d，共7d）。治疗前后检测患者体质量、白蛋白、谷胱甘肽（GSH）、握力的变化和肠功能不全的发生率。结果体质量两组治疗前后比较差异无显著性（P〉0．05）。白蛋白、握力和GSH Gl治疗后非常显著高于治疗前（P〈0．01）；白蛋白对照组治疗后较治疗前显著增高（P〈0．05），但握力和GSH治疗前后均无显著变化（P〉0.05）；肠功能不全的发生率Gln组为4．8％，显著低于对照组（28．6％，P〈0．05）。结论在危重病患者疾病早期通过静脉途径外源性地补充Gln，有效改善了患者的营养状况；使患者血浆中的GSH水平增高，加强了机体的抗氧化能力；减少了患者肠功能不全的发生率。

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. .
