基于仝小林院士脏腑风湿理论探讨新型冠状病毒肺炎康复期的中药治疗

仝小林院士将新型冠状病毒肺炎定名为"寒湿疫"，并以此理论为基础制定了初期、中期、重症期及恢复期的中医治疗方案，同时基于仝院士学术理论体系中的"脏腑风湿"理论，根据恢复期 "余毒未清，正虚邪恋"的病机特点，探讨其符合具备脏腑风湿行成3个基本要素：即外受寒湿裹挟戾气为必要外因；脏腑内虚为重要基础；邪疫伏留胶着，正邪交争为致病关键。故在辨证施治中可应用脏腑风湿理论以调理脾胃，化湿透邪，补益肺脾，顾护阳气，养阴生津。     

Lower body mass index and higher height are correlated with increased varicocele risk

To evaluate the anthropometric indexes in subjects with varicocele compared to controls and the incidence of varicocele in different body mass index (BMI) groups for the purpose of exploring the association between varicocele and anthropometric indexes. A comprehensive literature search was conducted by using PubMed, MEDLINE, EMBASE databases and Cochrane Library up to February 2019. A systematic review and meta‐analysis was conducted by STATA, and Newcastle–Ottawa Scale was utilised for assessing risk of bias. Ultimately, 13 articles containing seven case–control studies and six cross‐sectional studies with 1,385,630 subjects were involved in our study. Pooled results demonstrated that varicocele patients had a lower BMI (WMD = ?0.77, 95% CI = ?1.03 to ?0.51) and a higher height than nonvaricocele participants, especially in grade 3 varicocele patients. Subgroup analyses showed that normal BMI individuals had a higher risk of varicocele than obese or overweight individuals and a lower risk than underweight individuals. In conclusion, this study indicates that varicocele patients have a lower BMI and a higher height than nonvaricocele participants. Moreover, men with excess bodyweight have a lower incidence of varicocele compared to normal weight or underweight people. That is to say, high BMI and adiposity protect against varicocele and high BMI is associated with a decreased risk of varicocele.     

Prostaglandin signaling suppresses beneficial microglial function in Alzheimer’s disease models

Microglia, the innate immune cells of the CNS, perform critical inflammatory and noninflammatory functions that maintain normal neural function. For example, microglia clear misfolded proteins, elaborate trophic factors, and regulate and terminate toxic inflammation. In Alzheimer’s disease (AD), however, beneficial microglial functions become impaired, accelerating synaptic and neuronal loss. Better understanding of the molecular mechanisms that contribute to microglial dysfunction is an important objective for identifying potential strategies to delay progression to AD. The inflammatory cyclooxygenase/prostaglandin E2 (COX/PGE₂) pathway has been implicated in preclinical AD development, both in human epidemiology studies and in transgenic rodent models of AD. Here, we evaluated murine models that recapitulate microglial responses to Aβ peptides and determined that microglia-specific deletion of the gene encoding the PGE₂ receptor EP2 restores microglial chemotaxis and Aβ clearance, suppresses toxic inflammation, increases cytoprotective insulin-like growth factor 1 (IGF1) signaling, and prevents synaptic injury and memory deficits. Our findings indicate that EP2 signaling suppresses beneficial microglia functions that falter during AD development and suggest that inhibition of the COX/PGE₂/EP2 immune pathway has potential as a strategy to restore healthy microglial function and prevent progression to AD.     

激光联合复方血栓通胶囊治疗糖尿病视网膜病变合并黄斑水肿的疗效观察

目的:分析糖尿病视网膜病变合并黄斑水肿联合采用激光与复方血栓通胶囊治疗的临床疗效。方法:选取我院2017年1月—2019年1月收治的200例糖尿病视网膜病变合并黄斑水肿患者为研究对象,随机分为两组。对照组单独行激光治疗,观察组于对照组基础上联合复方血栓通胶囊治疗,对比两组临床疗效、治疗前后IL-6(白介素-6)、VEGF(血管内皮生长因子)、NOS(血清一氧化氮合成酶)水平变化情况。结果:对照组总有效率(68.00%,68/100)较观察组总有效率(98.00%,98/100)更高(P<0.05);与对照组对比,观察组治疗后NOS水平更高,IL-6、VEGF水平更低(P<0.05)。结论:糖尿病视网膜病变合并黄斑水肿联合采用激光与复方血栓通胶囊治疗的临床疗效显著,值得推广。     

沙利度胺联合TACE治疗原发性肝癌疗效与安全性的系统评价

目的:系统评价沙利度胺(thalidomide,TLD)联合肝动脉化疗栓塞术(transcatheter arterial chemoembolization,TACE)治疗原发性肝癌(primary hepatic carcinomas,PHC)的疗效和安全性.方法:计算机检索Cochrane Library(2014年第3期)、Web of Science(1986/2014-03)、Pub Med(1966/2014-03)、CNKI(1917/2014-03)、维普(1989/2014-03)、万方数据库(1998/2014-03),收集所有TLD联合TACE治疗PHC的随机对照试验.由两名评价员严格按照纳入标准选择文献,提取资料,并参照Cochrane系统评价的要求,对选择纳入的随机对照试验进行方法学质量评估后,采用Cochrane协作网提供的Rev Man 5.2软件对总有效率、疾病控制率、生活质量KPS评分、不同年限生存率、甲胎蛋白的变化、血管内皮生长因子(vascular endothelial growth factor,VEGF)的变化及不良反应发生率进行Meta分析.结果:最终纳入22项随机对照试验,包括1590例PHC患者,Meta分析结果显示,TLD联合TA C E组治疗P H C的总有效率(R R合并=1.29,95%C I:1.15-1.44)、疾病控制率(R R合并=1.27,95%CI:1.16-1.39)、生活质量KPS评分(MD合并=9.23,95%CI:6.90-11.55)、半年生存率(RR合并=1.10,95%C I:1.01-1.20)、1年生存率(RR合并=1.25,95%C I:1.13-1.39)、2年生存率(RR合并=1.45,95%CI:1.18-1.78)、3年生存率(R R合并=1.7 0,9 5%C I:1.1 6-2.5 0)、V E G F水平的变化(M D合并=-123.64,95%C I:-143.72--103.55)优于单纯TACE组,差异有统计学意义(均P0.05);不良反应发生率:在药物性皮疹发生率方面,TLD联合TACE组明显高于单纯TACE组,差异有统计学意义(RR=4.50,95%CI:2.34-8.64,P0.00001);在减少消化系应发生率(RR=1.08,95%CI:0.93-1.25)、降低骨髓抑制发生率(RR=1.12,95%CI:0.82-1.52)、降低肝功能异常发生率方面(R R=1.00,95%C I:0.72-1.39),T L D联合TA C E组与单纯TA C E组相近似,差异无统计学意义(均P0.05).结论:目前研究显示,与单纯TACE疗法相比,TLD联合TACE治疗PHC在总有效率、疾病控制率、生活质量KPS评分、半年生存率、1、2、3年生存率、降低V E G F方面具有明显的优势,但在安全性方面,TLD联合TACE组在药物性皮疹发生率方面明显高于单纯TACE组,而在消化系反应、骨髓抑制率、肝功能异常方面与单纯TACE组相似.
