喘息性支气管炎患儿皮肤过敏原点刺检测结果分析

目的探讨皮肤过敏原点刺试验检测喘息性支气管炎患儿临床效果。方法对2012年1月1日至12月31日于我院就诊并确诊为喘息性支气管炎的128例患儿进行皮肤过敏原点刺试验,总点数为1792点,选取的过敏原为粉尘螨、户尘螨等14种常见的过敏原,给予患儿皮肤过敏原点刺,对吸人性过敏原（粉尘螨、户尘螨、蓰草花粉、狗毛、梧桐等）及食物性过敏原（鸡蛋清、牛奶、海蟹、扇贝等）相关情况进行观察和过敏原阳性率等数据进行分析。结果128例喘息性支气管炎患者过敏原点刺检测结果为阳性占85．0％（1523／1792）,其中在吸人性过敏原中点刺检测结果阳性占74．1％（1328／1792）,而食物性过敏原阳性率为10．8％（1951／1792）。结论过敏原点刺试验能够快速方便地找出患儿的过敏原,并且能够有效地提示患者喘息性支气管炎病情的严重程度,能尽早进行干预及预防,过敏原点刺试验可以在临床上进一步推广。     

2006年深圳市急性肠胃炎的流行病学和病毒学调查

目的研究2006年深圳市急性肠胃炎发病的主要病因。方法收集深圳急性肠胃炎粪便样本200份（包含122份散发样本和78份暴发样本）,采用RT—PCR的方法进行急性肠胃炎相关病毒检测。结果44％（88／200）的样本为诺如病毒阳性,9％（18／200）为轮状病毒A阳性,2％（4／200）为星状病毒阳性,2％（4／200）为肠道腺病毒阳性,还有8％（16／200）的样本为混合感染。其中散发样本中检出腺病毒、轮状病毒、星状病毒和诺如病毒GI、诺如病毒GII5种病毒,而诺如病毒GII是3次暴发样本中的唯一病原。对22例NoVGII阳性样本测序后的系统发育分析表明NoVGII．4variants2006bcluster是造成2006年深圳市肠胃炎暴发的主要诱因．其次为NoVGII．12和GII．4Hunter簇。结论NoVGII．4是2006年流行于深圳的主要病毒株．     

RP-HPLC法测定五苓散中麦角甾醇和桂皮醛的含量

目的建立五苓散中麦角甾醇和桂皮醛的含量测定方法。方法五苓散样品经甲醇超声提取后,用HPLC法测定。色谱柱为HypersllC18（250mm×4.6mm,5μm）,流动相为甲醇-水梯度洗脱,流速为1mL.min-1,检测波长为283nm,柱温为30℃。结果麦角甾醇在0.0437~1.3098mg.mL-1浓度范围内线性关系良好（r=0.9991）,平均回收率为102.9%,RSD为1.5%（n=6）;桂皮醛在0。0062~0.1872mg.mL-1浓度范围内线性关系良好（r=1.0000）,平均回收率为97.8%,RSD为1.9%（n=6）。结论该方法简便、准确、可靠,可用于五苓散中麦角甾醇和桂皮醛的同时含量测定。     

一个中国Gilbert综合征家系的临床和遗传学特征分析

Objective To perform clinical and genetic pedigree analyses of a Chinese male patient with Gilbert's syndrome and his relatives. Methods Blood sample were collected from the proband and his relatives by liver function test, etiological examination and genetic analysis to exclude other related diseases. The phenobarbital-responsive enhancer module (PBREM) , TATA box and common mutation sites in exons of UGT1A1 gene were amplified by polymerase chain reaction (PCR) and the products screened by direct DNA sequencing. Results c. -3279T ＞ G in PBREM, TA insertion in TATA box and Gly71Arg were observed in this family. A linkage disequilibrium is also noted between c. -3279T ＞ G and TA insertion. In four affected members, three are heterozygotes and one is homozygote. The correlation between genotype and phenotype with a high serum level of unconjugated bilirubin was confirmed. Conclusion c. -3279T ＞ G in PBREM, TA insertion in TATA box and Gly71 Arg are essential for the pathogenesis of Gilbert's syndrome in this Chinese family. Gilbert's syndrome in this family is inherited in an autosomal recessive manner.
