基于网络药理学和分子对接探讨钩藤-全蝎药对治疗支气管哮喘的作用机制＊

目的通过网络药理学和分子对接探究钩藤-全蝎药对治疗支气管哮喘的药理作用机制。方法通过TCMSP、TCMIP数据库搜集钩藤、全蝎的活性成分及其作用靶点,并使用Cytoscape软件进行可视化分析成分-靶点网。通过OMIM、GeneCards数据库搜集支气管哮喘的疾病靶点,整合钩藤-全蝎药对与支气管哮喘的共有靶点。利用String平台构建对共有靶点互作PPI网络,并进行GO和KEGG富集分析,通过Cytoscape软件构建成分-靶点-通路网络模型。最后通过Autodock分子对接进行验证。结果经过筛选发现钩藤-全蝎药对37个活性化合物和234个药物靶点,与哮喘6010个靶点取交集得到35个共有靶点。钩藤-全蝎包含槲皮素、山奈酚、育亨宾碱、β-谷甾醇等重要活性成分;根据PPI网络分析,核心网络连接度高的潜在治疗靶点有IL6、CASP3、ECFR、ESR1、MAPK8等;根据KEGG富集分析结果显示,钩藤-全蝎药对主要通过PI3 K-Akt信号通路、TNF信号通路,HIF-1信号通路、M APK信号通路、NF-κB信号通路等来治疗哮喘;钩藤-全蝎药对活性成分与核心靶点的分子对接结果均显示出较好的结合活性。结论钩藤-全蝎药对治疗哮喘呈现出多成分、多靶点、多通路的特点,其核心成分槲皮素、山奈酚、育亨宾碱、β-谷甾醇等可能通过CASP3、MAPK8、ESR1、IL6、ECFR等靶点调节多条通路发挥抗炎、调节免疫、抗氧化应激、改善气道重塑等作用,从而对哮喘达到有效的治疗。     

Distribution of eight blood-group systems and ABH secretion in Mongolian,Korean, and Zhuang nationalities in China

Among different blood-group systems investigated here, the distribution of the ABO system varies most of all, followed by MNSs and P. Although there are differences in ABH secretion in the different populations, no striking regularity has been found. No significant difference has been found in the distribution of the blood-group systems Rhesus, Diego, Duffy, Kell and Kidd in these Chinese populations: the Rh (-) rate is less than 1%, the frequencey of Di^a is about 0·04, the frequency of Fy^a is rather high, the frequency of K extremely low and Jk^a is about 0·4.

In the three nationalities under study, Mongolians are characterized by a high frequency of I^B, M higher than 0·5 and a relatively high frequency of P₁. Koreans are characterized by a high frequency of I^A, slightly more M than N and rather high CDE in the Rh system. The peculiarities of the Zhuangs are a rather high frequency of I^O and M and the lowest frequency of P₁.     

Serum vascular endothelial growth factor receptor 3 as a potential biomarker in psoriasis

To discover novel biomarkers of psoriasis, a target‐specific antibody array screening of serum samples from psoriasis patients was initially performed. The results revealed that vascular endothelial growth factor receptor 3 (VEGFR‐3) was significantly elevated in the sera of psoriasis patients, compared to healthy controls. Next, ELISA validation studies in a larger cohort of psoriasis patients (N = 73) were conducted, which confirmed that serum VEGFR‐3 was indeed significantly increased in patients with psoriasis compared to healthy controls (P < 0.001). Furthermore, receiver operating characteristic curve analysis demonstrated that serum VEGFR‐3 exhibited potential in distinguishing healthy controls from psoriasis patients: area under the curve = 0.85, P < 0.001. In addition, serum levels of VEGFR‐3 were correlated with Psoriasis Area Severity Index scores (R = 0.32, P = 0.008) in psoriasis patients. Interestingly, serum VEGFR‐3 levels were significantly elevated in psoriatic arthritis compared to non‐psoriatic arthritis (P = 0.026). A pilot longitudinal study demonstrated that serum levels of VEGFR‐3 could reflect disease progression in psoriasis. Collectively, serum VEGFR‐3 may have a clinical value in monitoring disease activity of psoriasis.     

Is automatic CPAP titration as effective as manual CPAP titration in OSAHS patients? A meta-analysis

Purpose  

It is costly and time-consuming to conduct the standard manual titration to identify an effective pressure before continuous positive airway pressure (CPAP) treatment for obstructive sleep apnea (OSA) patients. Automatic titration is cheaper and more easily available than manual titration. The purpose of this systematic review was to evaluate the effect of automatic titration in identifying a pressure and on the improvement of apnea/hyponea index (AHI) and somnolence, the change of sleep quality, and the acceptance and compliance of CPAP treatment, compared with the manual titration.     

类风湿关节炎骨破坏及其针灸治疗的骨免疫学机制研究现状

免疫系统和骨骼系统共享多种信号通路和细胞因子，并通过免疫细胞与骨组织细胞相互连接，骨免疫学的主要内容即是研究两者之间相互作用的复杂关系，类风湿关节炎骨破坏的机制亦在于此。针灸具有良好的抗炎镇痛、调节免疫与内分泌、改善微循环等作用，其治疗类风湿关节炎骨破坏的机制主要包括调节破骨细胞、调节NF-κB受体激活蛋白配体（RANKL）-RANK-骨保护素（OPG）通路、调节炎症因子等。参考文献35篇。
