Matrine,oxymatrine, and compound Kushen injection from the roots of Sophora flavescens: an overview of their anticancer activities

In the present review, we updated current information on the chemistry, contents, and anticancer properties of matrine (MT), oxymatrine (OMT), and compound Kushen injection (CKI). The anticancer properties were focused on lung, breast, and liver cancer cells because they are most susceptible. Sources of information were from Google, Google Scholar, PubMed, PubMed Central, Science Direct, PubChem, J-Stage, Directory of Open Access Journals (DOAJ), and China National Knowledge Infrastructure (CNKI). Reference was also made on botanical websites, such as Flora of China and World Flora Online. MT and OMT are dominant quinolizidine alkaloids from the roots of Sophora flavescens (Kushen) of the family Fabaceae. Against lung, breast, and liver cancer cells, MT and OMT inhibit cell proliferation; induce cell cycle arrest, apoptosis, and autophagy; restrict angiogenesis; and inhibit cell metastasis, invasion, and migration. The processes involve various molecular targets and signaling pathways. CKI is a traditional Chinese medicine (TCM) composed of root extracts of S. flavescens and Smilax glabra (Baituling) of the family Smilacaceae. With MT and OMT as major components, CKI has been approved for the treatment of cancer in China more than 20 years ago. In recent years, systematic reviews and meta-analysis have been undertaken to evaluate the anticancer effects of CKI. When CKI is used alone and in combination with chemotherapy of western medicine, there is much to be learned concerning their interactions besides their individual and integrated efficacy. Some perspectives of MT, OMT, and CKI are discussed, and their suggestions for future research are provided.     

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。     

复方倍他米松注射液联合泛昔洛韦胶囊、普瑞巴林胶囊治疗带状疱疹的临床疗效观察

目的 对复方倍他米松注射液联合泛昔洛韦胶囊、普瑞巴林胶囊治疗带状疱疹的临床疗效进行观察并探讨。方法 选取2018 年1 月～2019 年12 月我院收治的118 例带状疱疹患者为研究对象，采用随机抽签的方式将患者分为对照组（泛昔洛韦胶囊+普瑞巴林胶囊+甲钴胺片+维生素B1 片）与观察组（联合复方倍他米松注射液），比较两组治疗总有效率、VAS 评分、QS 评分、C 反应蛋白、无新发皮疹时间、结痂时间及疼痛停止时间、随访2 个月后带状疱疹后遗神经痛发生率以及不良反应发生率。结果 观察组与对照组治疗总有效率分别为94.92%及76.27%，组间对比差异有统计学意义（P＜0.05）；治疗后，观察组VAS 评分显著低于对照组；观察组QS 评分低于对照组（P＜0.05）；治疗后，观察组C 反应蛋白显著低于对照组（P＜0.05）；观察组无新发皮疹时间、结痂时间及疼痛停止时间分别显著短于对照组（P＜0.05）；随访2 个月后，发现观察组带状疱疹后遗神经痛发生率显著低于对照组（P＜0.05）；观察组不良反应发生与对照组比较，差异无统计学意义（P＞0.05）。结论 复方倍他米松注射液联合泛昔洛韦胶囊、普瑞巴林胶囊治疗带状疱疹不仅效果好且安全性高，值得使用。     

Diagnostic sensitivity of electrophysiology and ultrasonography in ulnar neuropathies of different severity

ObjectiveTo assess the diagnostic performance of electrophysiology and nerve ultrasound in ulnar neuropathies of varying clinical severity in 135 consecutive patients.MethodsClinical severity of ulnar neuropathy was graded on a 4 point scale from very mild (symptoms only) to severe (marked atrophy of intrinsic hand muscles). Sensitivity and localization ability of electrophysiology and nerve ultrasound were assessed for each point of the scale.ResultsUltrasound had higher sensitivity than electrophysiology in clinically very mild (20% and 3% for ultrasound and electrophysiology, respectively) and mild (62% and 47% for ultrasound and electrophysiology, respectively) neuropathies, had greater localizing ability in axonal ulnar neuropathies, and identified nerve hypermobility.Ultrasound nerve cross-sectional area had strong positive correlation with both clinical and electrophysiological severity scores, but with significant overlap across the severity groups.ConclusionThe diagnostic work-up of ulnar neuropathies was improved by using both electrophysiology and ultrasound at all levels of clinical severity. Ultrasound increased the diagnostic yield in very mild and mild neuropathies, localized all the ulnar neuropathies with abnormal non-localizing electrophysiology and identified nerve hypermobility.SignificanceThis is the first detailed analysis of the diagnostic performance of electrophysiology and ultrasound in ulnar neuropathies of varying severity.
