欧洲、澳大利亚、英国生殖支原体感染诊疗指南介绍

【摘要】 生殖支原体可导致非淋菌性尿道炎、宫颈炎等泌尿生殖道感染甚至附睾炎、盆腔炎、早产等并发症。由于近年来生殖支原体感染率的升高以及多种常用治疗药物耐药的普遍出现，2016年欧洲、2017年澳大利亚性健康联盟、2018年英国性健康与HIV协会分别颁布了生殖支原体感染的诊疗指南，就其感染的临床表现、诊断、患者与性伴的治疗、随访等方面给出了建议，对我国生殖支原体感染的诊治有重要的指导意义。

阿伐斯汀联合氯雷他定治疗慢性难治性荨麻疹的多中心随机对照研究

【摘要】 目的 比较阿伐斯汀与阿伐斯汀联合氯雷他定治疗慢性难治性荨麻疹的疗效。方法 2017年3月至2018年12月，于4家中心采用多中心、随机对照的临床研究，联合治疗组慢性难治性荨麻疹患者口服阿伐斯汀胶囊8 mg每日3次及氯雷他定片10 mg每日1次，阿伐斯汀组口服阿伐斯汀胶囊8 mg每日3次及安慰剂10 mg每日1次，治疗4周。分别于治疗前、治疗1、2、4周随访，采集临床指标及记录不良反应事件。根据瘙痒、风团的数目、风团大小、每次发作持续时间、每周发作次数评估症状积分，使用症状积分下降指数（SSRI）评价疗效。采用重复测量的方差分析和χ2检验进行疗效和安全性评价。结果 联合治疗组53例、阿伐斯汀组59例纳入疗效分析。治疗前，两组症状积分、瘙痒视觉模拟评分差异均无统计学意义。治疗2周，联合治疗组痊愈19例、显效10例，有效率54.72%；阿伐斯汀组痊愈15例，显效6例，有效率35.59%。治疗4周，联合治疗组痊愈23例，显效9例，有效率60.38%；阿伐斯汀组痊愈20例，显效2例，有效率37.29%。治疗2、4周，联合治疗组有效率均高于阿伐斯汀组（χ2 = 4.13、5.96，均P < 0.05）。两组各随访时间点的SSRI差异、组间SSRI差异均有统计学意义（F = 8.62、4.38，均P < 0.05）。多变量方差分析，治疗2、4周时，联合治疗组SSRI（0.63 ± 0.05、0.68 ± 0.05）高于阿伐斯汀组（0.47 ± 0.05、0.51 ± 0.05），差异均有统计学意义（均P < 0.05）。联合治疗组发生药物相关性不良反应7例，阿伐斯汀组3例，主要表现为嗜睡、胃部不适、头痛、肝功能异常。结论 阿伐斯汀治疗慢性难治性荨麻疹安全、有效；阿伐斯汀联合氯雷他定可以显著提高疗效。     

加强我国猴痘的综合监测与公共卫生应对

【摘要】 猴痘是由猴痘病毒感染引起的人畜共患传染病，目前已有超过100个国家报告了猴痘病例。为了有效应对猴痘病例的输入以及传播，我国亟须加强包括入境监测、症状监测和人群监测的综合监测措施，同时做好针对传染源控制、传播途径阻断和重点人群防护的综合应对。     

Gambogic acid causes fin developmental defect in zebrafish embryo partially via retinoic acid signaling

Gambogic acid (GA), the major active ingredient of gamboge, has been approved by the Chinese Food and Drug Administration for clinical trials in cancer patients due to its strong anticancer activity. However, our previous research showed that GA was teratogenic against zebrafish fin development. To explore the teratogenicity and the underlying mechanisms, zebrafish (Danio rerio) embryos were used. The morphological observations revealed that GA caused fin defects in zebrafish embryos in a concentration-dependent manner. The critical exposure time of GA to reveal teratogenicity was before 8 hpf (hours post fertilization). LC/MS/MS analysis revealed that a maximum bioconcentration of GA was occurred at 4 hpf. Q-PCR data showed that GA treatment resulted in significant inactivation of RA signaling which could be partially rescued by the exogenous supply of RA. These results indicate the potential teratogenicity of GA and provide evidence for a caution in its future clinic use.     

The third-generation retinoid adapalene triggered DNA damage to induce S-phase arrest in HaCat cells

Epidermal proliferative diseases consisted of a series of common skin diseases, most of which were recurrent chronic skin diseases, and had greatly negative influence on the life quality of patient. Retinoids exhibited vital roles in the treatment of many skin diseases. Our recent study demonstrated that adapalene significantly inhibited the growth of HaCat cells, and the inhibitory activity was stronger than other retinoids, such as all-trans-retinoic acid, acitretin, isotretinoin, tazarotene, and bexarotene. Further study showed that adapalene suppressed the colony formation of HaCat cells, and it dramatically triggered S-phase arrest and apoptosis, rather than G1 phase arrest which was reported in other retinoids in several studies. Additionally, adapalene treatment greatly upregulated the protein expression of DNA damage marker γ-H2AX, which was in accord with the results of the elongation of tail moment by comet electrophoresis analysis. Moreover, DNA damage was triggered and DNA repair was suppressed synchronously with adapalene treatment, which accounted for the mechanism of S-phase arrest induced by adapalene. In summary, our recent work demonstrated that adapalene showed strong anti-proliferation activity in HaCat cells and could be an alternative agent for the epidermal proliferative disease.     

利妥昔单抗治疗寻常型天疱疮二例临床护理

寻常型天疱疮(pemphigus vulgaris,PV)是以全身皮肤黏膜糜烂、松弛性水疱为临床表现的慢性易复发性自身免疫性皮肤病[1]。目前主要通过抑制免疫系统,减少相关性特异性抗体的产生来治疗PV患者,临床常用糖皮质激素、环磷酰胺、硫唑嘌呤、静注人免疫球蛋白等治疗[2]。但是长期的免疫抑制会增加发生感染的风险和继发性肿瘤等严重的并发症[3]。
