H型高血压患者舌面诊图像颜色特征参数分析＊

目的 分析H型高血压患者的舌面诊图像颜色参数特征，探讨H型高血压患者的舌诊、面诊变化规律。方法 运用上海中医药大学自行研制的Smart TCM-1型中医舌面一体仪，采集高血压患者舌面诊图像，提取特征参数，分析健康对照组、H型高血压组与非H型高血压组患者舌面颜色参数特征。结果 ①在舌色各项参数中，H型高血压组舌尖部R值、B值、V值均显著小于健康对照组（P < 0.01）；非H型高血压组舌尖部B值显著小于健康对照组（P < 0.01），S值较健康对照组显著增大（P < 0.05）；H型高血压组舌尖部R、V值均明显小于非H型高血压组（P < 0.05）。在舌苔各项参数中，H型高血压组舌中H值、V值均明显小于健康对照组（P < 0.05）；非H型高血压组舌中V值、舌右V值均显著小于健康对照组（P < 0.01）；H型高血压组舌中H值明显小于非H型高血压组（P < 0.05），右侧舌苔S值明显大于非H型高血压组（P < 0.05）。②H型高血压组面色参数鼻G值、下颌G值、口唇R值、口唇V值均明显小于健康对照组（P < 0.05）；非H型高血压组前额H值、目眶H值、脸颊H值、鼻H值、下颌H值、整体H值均明显大于健康对照组（P < 0.05）；H型高血压组前额H值、目眶G值、目眶H值、脸颊H值、鼻G值、鼻H值、下颌R值、下颌G值、下颌H值、下颌V值、口唇R值、口唇G值、口唇V值、整体R值、整体G值、整体H值、整体V值均明显小于非H型高血压组（P < 0.05）。结论 H型高血压患者苔色偏黄，以舌中部为主，且舌右侧黄苔积聚较明显；H型高血压患者面色为黄中带红，口唇、下颌部更为晦暗。H型高血压患者的舌、面诊特征参数的变化，与高血压病阳亢湿盛病机相符。     

Systematic review of optical coherence tomography usage in the diagnosis and management of basal cell carcinoma

Optical coherence tomography (OCT) is a noninvasive imaging tool used in vivo in real time for diagnosis, treatment delineation and monitoring of basal cell carcinoma (BCC). Features of BCC on OCT have been widely described and reviewed. However, the diagnostic accuracy of OCT in these various applications is unclear. We systematically reviewed the literature to assess the accuracy of OCT in diagnosis and management of BCC using the Embase and Medline databases. In total 179 unique references were identified in the initial search, of which 22 studies with 556 histologically proven BCCs were eligible. Assessment of the quality of eligible studies was undertaken using the STROBE criteria. Data extraction and quality assessment were performed independently by the two authors. This systematic review provides an overview of the clinical applications of OCT in the diagnosis and management of BCC. OCT has been suggested to be useful in the diagnosis, treatment planning and treatment monitoring of BCC. As the technology improves and its utility increases, further studies with good methodological quality will be needed to implement OCT into daily practice.     

The quality of spontaneous adverse drug reaction reports from the pharmacovigilance centre in western China

Background: High-quality adverse drug reaction (ADR) reports are essential for conducting drug safety monitoring in pharmacovigilance. The study aim was to assess the current quality of ADR reports in western China, and to identify problems with ADR report quality.

Research design and methods: A sample of 1139 reports received by the Shaanxi ADR Monitoring Center from January 2015 to December 2017 was selected. ADR report quality was evaluated using an ADR report quality evaluation system.

Results: None of the reports were rated as excellent and 1.40% (n = 16) as good. Report quality was better for new and serious reports than for general reports. Medical institutions generated higher quality reports than pharmaceutical manufacturers. Nurses generated higher quality reports than doctors, pharmacists, and other professionals. Reporters of different occupations showed significant differences in the quality of the indicators Reporting time limit, Intervention ADR time, ADR termination time, ADR intervention measures, Original disease, and Cause of medication (P = 0.000).

Conclusions: The ADR data quality was poor in western China, and of lower quality than reported data from previous research in other regions. Improvements in the quality and availability of ADR reports are urgently needed.

益母草对子宫的药理作用研究进展

益母草是著名的经产良药,具有"调经"功效,自古以来是治疗妇人"经产带下"之良药。子宫是益母草"调经"功效的重点靶器官。本文通过对益母草对子宫的药理作用研究进行梳理,显示益母草对子宫有双向调节子宫收缩活动、调节子宫肌电、保护子宫内膜和促进子宫内膜复旧、抗子宫内膜炎等多种作用,其作用的发挥与益母草的入药品种与炮制、提取成分和子宫状态密切相关。本文对指导益母草质量提升和临床应用有参考意义。     

miRNA93和miRNA192在H3N2亚型SIV病毒复制及宿主抗病毒免疫中的作用

目的 探讨分离于广西猪流感病毒SW/Guangxi/NS2783/2010和SW/Guangxi/NS650/2012跨种属感染人肺腺癌A549细胞的miRNA93和miRNA192对病毒复制及宿主抗病毒免疫的影响。方法 通过测定不同稀释浓度的病毒感染细胞HA滴度值,确定病毒最佳稀释浓度。荧光定量PCR检测病毒感染细胞后miRNA93和miRNA192表达,Western blot检测病毒NP和HA蛋白表达水平;转染miRNA93和miRNA192抑制剂后,重新检测miRNA93、miRNA192、IFN-β及病毒NP、HA蛋白表达水平。结果 不同稀释度病毒感染人A549细胞后HA滴度的结果显示病毒SW2783的最佳稀释度为10^-3,而SW650的HA滴度无明显变化趋势,提示病毒SW2783对人A549细胞具有较好的适应性和感染能力。荧光定量PCR和Western blot结果提示两株病毒感染细胞后病毒NP和HA蛋白表达均先升高后降低,加入miRNA93抑制剂,两株病毒NP和HA蛋白的表达均上调;加入miRNA192抑制剂,病毒SW2783的HA蛋白表达下调（P=2.10×10^-4）,而SW650的HA蛋白表达上调（P=5.45×10^-5）,NP蛋白反而下调（P=0.034）;ELISA结果提示病毒SW2783和SW650感染细胞后炎症因子IFN-β表达水平随感染时间延长而升高。结论 研究表明miRNA93和miRNA192的表达与SIV病毒增殖及宿主抗病毒免疫有关,可作为干预猪流感病毒跨种属感染的新靶点。
