52例囊虫性脑小脓肿的病理观察

对52例因癫痫发作就诊,CT检查在脑内发现小脓肿的病例,手术切除标本进行了寄生虫学检查,证实为脑囊虫病患者。取脓肿壁作病理切片,病理检查发现5例囊虫仍存活并伸出头节,16例囊虫虽死亡但虫体尚完整,14例在切片中查见了虫体成分。结果表明病变组织的坏死和炎症反应以完整死虫组最显著;至囊虫残破炎症逐渐缓和,增生性变化渐占优势,脓肿腔缩小;有3例硬结纤维化;钙质沉积罕见。对脑内囊虫性小脓肿的形成以及病变与CT影像之间的相关性进行了讨论。

甘草酸铵调控IL-33/ST2通路对特应性皮炎小鼠肥大细胞活化的影响

目的 研究甘草酸铵对特应性皮炎（AD）小鼠IL-33/ST2通路及肥大细胞的活化情况的影响。方法 72只ICR小鼠（雌雄各半）随机均分为对照组、模型组及甘草酸铵低、中、高剂量（25、50、100 mg/kg）和泼尼松龙（阳性药,60 mg/kg）组。除对照组外,以丙酮-DNCB为致敏源构建AD小鼠模型,建模后各组ip相应药物,对照组和模型组ip生理盐水。记录小鼠夜间搔抓次数;甲苯胺蓝患处皮肤组织染色法观察肥大细胞活化情况;ELISA法检测白细胞介素（IL）-33和ST2血清学水平;实时荧光定量PCR（qRT-PCR）和Weston blotting法检测皮肤组织中的IL-33和ST2 mRNA和蛋白水平。结果 与对照组比较,模型组小鼠的搔抓次数显著增多（P<0.05）,肥大细胞密度显著升高（P<0.05）,IL-33和ST2的血清学水平、皮肤组织的转录水平和蛋白表达水平均显著升高（P<0.05）;与模型组比较,泼尼松龙组和甘草酸铵低、中、高剂量组的搔抓次数和肥大细胞密度分别显著减少和降低（P<0.05）,IL-33、ST2的血清学水平、皮肤组织mRNA和蛋白表达均显著降低（P<0.05）。结论 甘草酸铵能够明显抑制AD模型小鼠IL-33和ST2的血清学水平、皮肤组织中的转录水平和蛋白表达,降低了肥大细胞的活化程度,从而减轻AD的瘙痒症状。

Collagen type XVIII alpha 1 chain (COL18A1) variants affect the risk of anti‐tuberculosis drug‐induced hepatotoxicity: A prospective study

BackgroundThe role of collagen type XVIII alpha 1 chain (COL18A1) in anti‐tuberculosis drug‐induced hepatotoxicity (ATDH) has not been reported. This study aimed to explore the association between of COL18A1 variants and ATDH susceptibility.MethodsA total of 746 patients were enrolled in our study from December 2016 to April 2018, and all subjects in the study signed an informed consent form. The custom‐by‐design 2x48‐Plex SNPscanTM kit was used to genotype all selected 11 SNPs. Categorical variables were compared by chi‐square (χ²) or Fisher''s exact test, while continuous variables were compared by Mann‐Whitney''s U test. Plink was utilized to analyze allelic and genotypic frequencies, and genetic models. Multivariate logistic regression analyses were used to adjust potential factors. The odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were also calculated.ResultsAmong patients with successfully genotyping, there were 114 cases and 612 controls. The mutant A allele of rs12483377 conferred the decreased risk of ATDH (OR = 0.13, 95%CI: 0.02–0.98, P = 0.020), and this significance still existed after adjusting age and gender (P = 0.024). The mutant homozygote AA genotype of rs12483377 was associated with decreased total protein levels (P = 0.018).ConclusionOur study first revealed that the A allele of COL18A1 rs12483377 was associated with the decreased risk of ATDH in the Western Chinese Han population, providing new perspective for the molecular prediction, precise diagnosis, and individual treatment of ATDH.
