基于TGF-β/smad信号通路探讨七方胃痛颗粒对人胃腺癌AGS细胞上皮间质转化过程的影响＊

目的 探究七方胃痛颗粒对转化生长因子-β1（TGF-β1）诱导人胃腺癌细胞AGS上皮间质转化（Epithelial-mesenchymal transition， EMT）过程的影响及其潜在分子机制。方法 为了探究七方胃痛颗粒对TGF-β1处理的AGS细胞增殖、迁移和侵袭的影响，实验分为四组：AGS细胞对照组，EMT空白模型组，中药血清组，TGF-β/smad通路抑制剂组，分别利用CCK8、细胞划痕实验和Transwell实验检测细胞增殖、迁移和侵袭能力。此外，通过免疫荧光检测EMT过程中相关蛋白（E-cadherin、N-cadherin、14-3-3ζ、Smad2和p-Smad2/3）的表达水平。结果 与AGS细胞对照组相比，TGF-β1诱导EMT过程，显著促进AGS细胞增殖、迁移和侵袭，下调了E-cadherin的表达，上调了N-cadherin、14-3-3ζ、Smad2和p-Smad2/3的表达；与EMT空白模型组相比，中药血清组、TGF-β/smad通路抑制剂组显著抑制了细胞增殖、迁移和侵袭，上调了E-cadherin的表达，降低了N-cadherin、14-3-3ζ、Smad2和p-Smad2/3的表达。结论 七方胃痛颗粒通过调控TGF-β/smad信号通路从而抑制人胃腺癌AGS细胞的EMT过程。     

Chinese herbal injections combined with rt-PA intravenous thrombolysis for acute ischemic stroke: A systematic review and meta-analysis protocol

Background:Acute ischemic stroke (AIS) is an important factor leading to adult death and disability globally. For AIS patients who meet certain conditions, recombinant tissue plasminogen activator (rt-PA) intravenous thrombolysis is an important method recommended by national guidelines to achieve vascular recanalization. However, complications such as hemorrhagic transformation and vascular reocclusion after thrombolysis are still unsolved problems in clinical. Several systematic reviews of clinical randomized controlled trials (RCTs) in the past have shown that Chinese herbal injections (CHIs) can improve the neurological function of patients, increase the tolerance of ischemic tissues to hypoxia, and inhibit platelet aggregation. Therefore, this study conducted a meta-analysis of AIS treatment with intravenous thrombolysis alone and compared it with the combined application of CHIs. To evaluate whether CHIs have a synergistic effect on thrombolytic therapy and provide a basis for clinical application.Methods:The following databases will be searched until September 2020: ①English databases: PubMed, Cochrane Library, Embase; ②Chinese databases: CNKI, Wanfang database, Weipu database, SinoMed. RCTs will be included to compare the efficacy of thrombolysis combined with CHIs and thrombolysis alone in the treatment of AIS. Data extraction and risk of bias assessments will be carried out by 2 verifiers independently. The risk of bias will be evaluated through the Cochrane risk of bias tool. Review Manager software 5.3 will be used for statistical analysis.Results:This study will provide comprehensive evidence for the treatment of AIS by CHIs combined with intravenous thrombolysis from multiple aspects.Conclusion:The conclusion of the meta-analysis will provide a basis for judging whether CHIs combined with intravenous thrombolysis is an effective measure for the treatment of AIS.Ethics and dissemination:Ethical approval is not needed because this study will be based on data that already published. We will publish the findings of this study in a peer-reviewed journal and related conferences.PROSPERO registration number:CRD42020215546.     

理肺消积丸对Lewis肺癌小鼠肿瘤生长的抑制作用

目的:观察理肺消积丸对Lewis肺癌小鼠肿瘤生长的影响作用。方法:将50只小鼠随机分为空白对照组、模型对照组、理肺消积丸组[240μg/(g·d)]、顺铂组[0.5μg/(g·d)]、联合组[理肺消积丸240μg/(g·d)+顺铂0.5μg/(g·d)]。采用皮下接种法建立Lewis肺癌小鼠模型,制备模型次日进行药物干预。2周后分别采用活体成像技术检测小鼠体内肿瘤生长情况,HE染色评价肿瘤组织病理学形态,免疫组化技术观察肿瘤细胞增殖细胞核抗原(Proliferating cell nuclear antigen,PCNA)及人第10号染色体缺失的磷酸酶及张力蛋白同源物(gene of phosphate and tension homology deleted on chromosome ten,PTEN)的表达情况,TUNEL技术评价肿瘤细胞凋亡情况。结果:模型对照组小鼠体内肿瘤增殖明显,肿瘤细胞异型性明显、核分裂象多见,PCNA蛋白表达程度极高,而细胞凋亡率及PTEN蛋白表达量极低。与模型对照组对比,理肺消积丸组的肿瘤生长受到抵制,肿瘤细胞异型性及核分裂象减少,PCNA蛋白表达下降,肿瘤细胞凋亡率升高,PTEN蛋白表达升高,差异均有统计学意义(P<0.05)。而顺铂组和联合组除PTEN蛋白表达较模型对照组差异无统计学意义外,其余指标均有统计学意义。结论:理肺消积丸可显著抑制Lewis肺癌小鼠肿瘤生长,其机制可能与其抑制肺癌细胞增殖、上调细胞凋亡和PTEN蛋白表达有关。     

罗仁治疗儿童肾病综合征蛋白尿经验介绍＊

本文介绍了罗仁教授治疗儿童肾病综合征蛋白尿的学术思想及理法方药。肾病综合征蛋白尿属中医学的“水肿”“尿浊”“虚劳”“腰痛”范畴，发病主要与肺、脾、肾三脏功能失调有关。蛋白尿是肾病综合征的必要诊断条件，不仅可直接导致低蛋白血症，引发水肿，还会促进肾功能的恶化。罗仁教授认为尿蛋白源于血浆，是水谷精微，为至阴之精，应固藏于肾，并且有赖于肺之宣发、脾之升清、肝之疏泄的共同作用，创立了肾病1号方从肺、脾、肝、肾四方面减少尿蛋白，使患者更早进入缓解期，延缓疾病进展，调节免疫，防止复发，尤其对激素抵抗、激素依赖患者具有更重要的意义，并随证或随症加减，对于病情复杂的复合病或复合证患者可用单双日疗法调整阴阳，单日用肾病1号方减少蛋白尿，双日用小生六汤调和脏腑，还从心理、运动、饮食三方面指导患者积极面对疾病。     

High expression of HVEM is associated with improved prognosis in intrahepatic cholangiocarcinoma

Herpesvirus entry mediator (HVEM) displays dual signals in T-cell activation according to the ligands and intracytoplasmic effectors it interacts with. High HVEM expression may play an immunosuppressive role in several malignancies. The present study investigated the clinical impact of HVEM on intrahepatic cholangiocarcinoma (ICC), including its prognostic value, and association with clinicopathological features and immune status. The clinical data of 102 consecutive patients with ICC who underwent surgical treatment from January 2012 to December 2017 were collected. The expression of HVEM and different types of tumor-infiltrating lymphocytes (TILs) were investigated in ICC tissue samples by immunohistochemical staining. HVEM expression was detected in the tumor tissues of 92 (90.2%) patients with ICC. Patients with high HVEM expression were more likely to have increased peripheral blood lymphocyte (PBL) concentrations (P=0.031), decreased CEA (P=0.036), low TNM stage (P=0.043) and high frequencies of small-duct histological type (P=0.021) and BAP1 retained expression (P=0.010). Survival analysis showed that high HVEM expression was a favorable independent predictor of overall postoperative survival (P=0.034, hazard ratio=0.486, 95% confidence interval=0.249–0.945). In addition, no significant association of HVEM expression with CD4⁺ (P=0.512), CD8⁺ (P=0.750) or CD45RO⁺ (P=0.078) TILs was identified in the ICC tissues. These results indicate that HVEM may serve as a favorable prognostic marker for ICC. Furthermore, co-stimulatory signals from HVEM may play a dominant role in the progression of ICCs, which can be explained by an increase in the number of PBLs rather than a change in the number of TILs. However, the function of the HVEM network in ICC progression is complex and requires further study.     

肾透明细胞癌不同CT影像学征象对患者术后康复情况的影响

目的探究肾透明细胞癌不同CT影像学征象对患者术后康复情况的影响。方法选取2010年1月到2014年4月我院收治的50例肾透明细胞癌患者的CT征象,进行T分期,并分析不同CT征象与患者预后关系。结果利用CT征象进行T分期区别主要在T3a期,T3a期分为T3a-CT(10例)和T3a-仅病理(6例),T3a-仅病理CT分期可分为T1期2例,T2期4例;单因素分析显示,肿瘤大小、肿瘤是否侵及肾被膜外、是否侵及肾窦集合系统、是否侵及肾静脉及分支、是否侵及下腔静脉、有无广泛性坏死、是否存在囊性改变、瘤周是否受侵、瘤周是否存在新生血管与5年生存率具有一定相关性(P<0.05);多因素回归分析显示,肿瘤≥7cm、肿瘤穿透肾被膜、肾静脉及分支受侵、下腔静脉受侵、肿瘤无囊变、瘤周受侵及瘤周新生血管是影响肾透明细胞癌预后的独立危险因素(P<0.05)。结论肾透明细胞瘤患者肿瘤大于7cm、肿瘤穿透肾被膜、肾静脉及分支受侵、下腔静脉受侵、肿瘤无囊变、瘤周受侵及瘤周新生血管是影响肾透明细胞癌预后的独立危险因素,肿瘤周围受侵及瘤周新生血管形成可降低患者5年生存率,而肿瘤囊变可作为预测术后康复情况较好的标志之一。
