马鞭草全长转录组测序分析

目的:利用高通量测序技术获得马鞭草Verbena officinalis L.的全长转录组基因信息。方法:通过PacBio Sequel高通量测序平台,对马鞭草根、茎、叶3个部位的混合样品进行全长转录组测序,并基于序列同源性对转录本进行功能注释,得到马鞭草全长转录组的遗传信息。结果:测序数据经过质控后获得197542个高质量的转录本及169063条环形一致性序列(CCS),检测出4955个转录因子。其中161062个(81.53%)转录本在非冗余蛋白(NR)、真核生物相邻类的聚簇(KOG)数据库、京都基因与基因组百科全书(KEGG)、基因本体(GO)数据库、蛋白家族(Pfam)数据库和SwissProt蛋白序列数据库中均得到注释。MISA分析发现54063个简单重复序列(SSR)位点,还预测到70050个长链非编码RNAs(lncRNAs)和45499个信使核糖核酸(mRNAs),并在马鞭草全长转录组中共鉴定到了60个转录本可能参与单萜类化合物的生物合成。结论:利用高通量测序技术和生物信息学分析获得了马鞭草的全长转录组信息特征,可为后期开展马鞭草功能基因鉴定、解析萜类化合物次生代谢途径及其调控机制提供参考。     

Clinicopathological characteristics,prognosis, and chemosensitivity in patients with metastatic upper tract urothelial carcinoma

PurposeTo investigate the clinical characteristics, chemosensitivity, and outcome of metastatic upper tract urothelial carcinoma (UTUC).Patients and MethodsRecords of patients with metastatic UTUC since January 2005 were retrieved from a database that included clinical and survival data. Statistical analyses including survival and multivariate analyses of factors were respectively performed by the Kaplan-Meier method and Cox proportional hazard model.ResultsA total of 250 consecutive UTUC cases were evaluated. There were 56 patients (22.4%) with initially diagnosed stage IV disease. The most common metastatic sites were lung (39.6%), distant lymph nodes (39.2%), bone (19.6%), liver (18.0%), and adrenal gland (7.2%), respectively, and the local recurrence rate was 10.4%. Two hundred thirteen patients received first-line chemotherapy. The overall response rate was only 28.7% and the median progression-free survival time was only 5.0 months. The overall survival time of the cohort was 18.0 months. Multivariate analyses showed that initially diagnosed stage IV disease, number of metastatic organs ≥3, no response to chemotherapy and cycles of chemotherapy ≤2 were adverse prognosticators for overall survival.ConclusionUTUC presented to be more prone to metastasize than locally recur and thought to have low chemosensitivity. Stage IV disease at initial diagnosis, number of metastatic organs, response and cycles of chemotherapy were independent prognosticators for metastatic UTUC.     

阿帕替尼和替吉奥对结肠癌治疗效果的系统评价和Meta分析

目的通过系统评价和Meta分析探讨阿帕替尼与替吉奥对比治疗结肠癌的有效性和安全性。方法以"阿帕替尼""替吉奥""结肠癌""等为中文关键词,以"Apatinib""Tegafur""Colon cancer"等为英文关键词,检索PubMed,Cochrane Library,Embase,Web of Science,中国知网、中国生物医学文献服务系统、维普数据库、万方数据知识服务平台,时间限制在从建库到2020年12月。评价阿帕替尼和替吉奥对结肠癌的总体疗效,结肠癌进展和无进展生存期的差异。研究采用RevMan 5.3软件进行Meta分析。结果Meta分析结果显示,阿帕替尼与替吉奥对结肠癌的疗效相比,部分缓解+稳定的差异没有统计学意义(RR=1.10,95%CI,0.71~1.71,P=0.640),在结肠癌进展方面的差异没有统计学意义(RR=0.51,95%CI:0.28~1.32,P=0.205),在无进展生存期方面阿帕替尼组大于替吉奥组,差异具有统计学意义(SMD=0.90,95%CI;0.42~1.37,P<0.0001)。结论相较于替吉奥,阿帕替尼用于治疗结肠癌患者能明显延长无进展生存期,总体生存效益有所提高。     

内镜下全腹膜外Sublay修补在腹壁疝中的应用

目的评价腹壁疝内镜下全腹膜外Sublay(TES)手术的效果并总结经验。方法回顾性总结国内10所医院自2016年3月至2019年7月115例腹壁疝内镜下TES手术的患者资料。分析患者情况、疝的特点、手术经过和结果。结果115例计划实施TES的患者中,因严重腹膜破损中转为IPOM修补患者1例,其余均成功手术。可以缝合缺损患者108例(94.74%),需要永久补片固定患者15例(13.16%)。放置引流患者76例(66.67%),中位手术时间为144 min,术中无严重并发症发生。随访时间3~45个月,总并发症发生率为20例(17.54%),其中出现血清肿患者5例(4.38%)。绝大多数患者术后仅出现轻微疼痛,未出现慢性疼痛。结论在腹壁疝的治疗中,对熟悉腹壁解剖的外科医师而言,TES是一种有效、安全的修复手段。在熟悉手术的基础上适应症可逐步拓展。     

Polyphenols intervention is an effective strategy to ameliorate inflammatory bowel disease: a systematic review and meta-analysis

Abstract

Whether polyphenols could ameliorate inflammatory bowel disease (IBD) is still conflicting. To explore the efficacy of polyphenols as an adjuvant therapy for IBD, we conducted this systematic review and meta-analysis. Literature search was performed using PubMed, Web of Science, Scopus and Cochrane databases. Finally, 12 randomized controlled trials (RCTs) were included. In contrast to control group, curcumin treatment significantly improved clinical remission in intention-to-treat (ITT) (OR = 3.36, 95% CI: 1.09–10.37) and per-protocol (PP) analysis (OR = 5.13, 95% CI: 1.84–14.27). Meanwhile, curcumin could significantly ameliorate endoscopic remission (OR = 5.69, 95% CI: 1.28–25.27) and clinical response (OR = 4.69, 95% CI: 1.03–21.47) in PP analysis. Heterogeneity was present across the studies. In conclusions, polyphenols might be an effective adjuvant treatment for ameliorating IBD. Considering the relatively few studies included in our present study, further clinical trials are required to verify the effects of polyphenols on IBD.
