2010—2020年北京市房山区梅毒防治效果分析

目的了解北京市房山区梅毒规划(2010—2020年)实施期间梅毒防治效果和各考核指标达标情况,为下一步制定有效的梅毒防治策略提供科学依据。方法根据《中国预防与控制梅毒规划(2010—2020年)》(以下简称《梅控规划》)终期评估的要求,通过专网、现场调查、APP答题等方式对涉及的16个指标进行收集,并将16个指标划分为梅毒防治保障措施的落实、防治工作开展和防治效果3个层面进行评估,同时将评估结果与终期评估标准进行比较。采用SPSS 18.0软件进行描述性统计分析。结果2010—2020年北京市房山区共报告梅毒病例3260例,年均报告发病率27.99/10万,年均增长0.08%,男女比例基本持平,以25岁年龄组病例数最多,历年病例均以隐性梅毒为主。保障措施与能力建设方面均达标;防治工作方面:感染梅毒的孕产妇所生婴幼儿接受规范诊疗服务的比例为50.00%,梅毒患者接受规范化治疗的比例86.11%,两指标未达标,其余均达标;防治效果中一期和二期梅毒年报告发病率增长幅度为3.80%,未达标,先天梅毒年报告发病率为9.25/10万活产数达到了《梅控规划》的工作要求。结论2010—2020年北京市房山区梅毒防治工作取得了一定成效,但部分指标仍未达标,应继续加强梅毒防治工作,尤其是需提高规范化诊疗的比例同时控制新发梅毒发病率。

Analysis on internal mechanism of zedoary turmeric in treatment of liver cancer based on pharmacodynamic substances and pharmacodynamic groups

Zedoary tumeric (Curcumae Rhizoma, Ezhu in Chinese) has a long history of application and has great potential in the treatment of liver cancer. The anti liver cancer effect of zedoary tumeric depends on the combined action of multiple pharmacodynamic substances. In order to clarify the specific mechanism of zedoary tumeric against liver cancer, this paper first analyzes the mechanism of its single pharmacodynamic substance against liver cancer, and then verifies the joint anti liver cancer mechanism of its "pharmacodynamic group". By searching the research on the anti hepatoma effect of active components of zedoary tumeric in recent years, we found that pharmacodynamic substances, including curcumol, zedoarondiol, curcumenol, curzerenone, curdione, curcumin, germacrone, β-elemene, can act on multi-target and multi-channel to play an anti hepatoma role. For example, curcumin can regulate miR, GLO1, CD133, VEGF, YAP, LIN28B, GPR81, HCAR-1, P53 and PI3K/Akt/mTOR, HSP70/TLR4 and NF-κB. Wnt/TGF/EMT, Nrf2/Keap1, JAK/STAT and other pathways play an anti hepatoma role. Network pharmacological analysis showed that the core targets of the "pharmacodynamic group" for anti-life cancer are AKT1, EGFR, MAPK8, etc, and the core pathways are neuroactive live receiver interaction, nitrogen metabolism, HIF-1 signaling pathway, etc. At the same time, by comparing and analyzing the relationship between the specific mechanisms of pharmacodynamic substance and "pharmacodynamic group", it is found that they have great reference significance in target, pathway, biological function, determination of core pharmacodynamic components, formation of core target protein interaction, in-depth research of single pharmacodynamic substance, increasing curative effect and so on. By analyzing the internal mechanism of zedoary tumeric pharmacodynamic substance and "pharmacodynamic group" in the treatment of liver cancer, this paper intends to provide some ideas and references for the deeper pharmacological research of zedoary tumeric and the relationship between pharmacodynamic substance and "pharmacodynamic group".     

Diagnosis of intrahepatic cholangiocarcinoma by Raman spectroscopy provides high efficiency: A protocol for systematic review and meta-analysis

Background:We aim to evaluate the efficiency of Raman spectroscopy (RS) in diagnosing suspected patients with intrahepatic cholangiocarcinoma (ICC), manifested by diagnostic sensitivity, specificity, and accuracy.Methods:We will research widely the articles concerning the use of RS in ICC through authenticated database including PubMed/Medline, EMBASE, Web of Science, Ovid, Web of Knowledge, Cochrane Library, and CNKI between January 2012 and November 2020, retrieving at least 1500 spectra with strict criteria. This study will be carried out in accordance to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We are going to summarize the test performance using random effects models.Results:Based on the pooled sensitivity, specificity, and diagnostic accuracy, we intend to provide the relative diagnostic efficiency in ICC through RS.Conclusion:Through this systematic review and meta-analysis, we intend to provide the pooled sensitivity, specificity and diagnostic accuracy of RS in the diagnosis of suspected ICC. Other parameters like positive likelihood ratios (LR), negative LR, diagnostic odds ratio (DOR), and area under curve (AUC) of the summary receiver operating characteristics (SROC) curve will also be calculated and related figures will be drawn to help illustrate the efficacy of RS in the diagnosis of ICC.
