miR-122 Inhibits Hepatocarcinoma Cell Progression by Targeting LMNB2

In the present study, we investigated the role of miR-122 in hepatocarcinoma progression and explored the mechanism. In hepatocarcinoma tissues and cells, we used qRT-PCR to validate the miR-122 expression level. Next, we used colony formation by crystal violet staining assay to compare cell proliferation ability, and we used scratch test or Transwell assay to compare cell migration or invasion ability. We then conducted bioinformatics or luciferase reporter gene assay to prove the regulation effect of miR-122 on lamin B2 (LMNB2), and the biological function of LMNB2 was analyzed. We used nude mouse tumorigenicity assay to test the inhibition effect of miR-122 ASO therapy against hepatocarcinoma. miR-122 was reduced in hepatocarcinoma tissues compared to the paracarcinoma tissues, which was relatively low or high in hepatocarcinoma cell line SMMC7721 or Hep3B, and overexpressed miR-122 inhibited proliferation, migration, and invasion in hepatocarcinoma cells. Additionally, some reports showed that LMNB2 was regulated by miR-122, which inhibited the expression of LMNB2. Moreover, LMNB2 functioned to promote cell proliferation, migration, and invasion. We could achieve the inhibition of hepatocarcinoma using miR-122 therapy through decreasing LMNB2 expression in vivo. Our data indicated that miR-122 could inhibit hepatocellular carcinoma cell progression by targeting LMNB2 and as a therapeutic target for hepatocarcinoma treatment.     

Hypertension is a risk factor for adverse outcomes in patients with coronavirus disease 2019: a cohort study

Abstract

Background

Comorbidities are commonly seen in patients with coronavirus disease 2019 (COVID-19), but the clinical implication is not yet well-delineated. We aim to characterize the prevalence and clinical implications of comorbidities in patients with COVID-19.     

从武汉抗疫看中医药文化认同与新的医学模式

从武汉抗疫中医药的投入使用情况,反思现代临床和国人所呈现出的中医药文化认同和就医习惯,探索其历史文化根源及社会因素与医学发展的内在关联。回顾历史,中医屡次临危受命,不负重托,如今大疫当前,中医药再次发挥了重要作用。故新时代探讨如何遵循中医药发展规律,传承精华、守正创新,坚持中医药原创优势,形成中医药学科优势整体化呈现的新模式医学,对提升全社会的中医药认知度具有重要意义。     

肾母细胞瘤MIB-1（Ki-67增殖指数）和p27kip1表达及与预后的关系

目的:探讨肾母细胞瘤MIB-1（Ki-67增殖指数）和细胞周期蛋白依赖性激酶抑制剂p27kip1的表达及与预后的关系。方法:经医院伦理委员会批准，连续纳入2008年1月至2013年8月在我院就诊的肾母细胞瘤患者样本作为研究对象，观察p27kip1和MIB-1阳性表达与患者临床特征的关系。结果:肿瘤组织中MIB-1阳性表达率高于正常肾组织，p27kip1阳性表达率低于正常肾组织，差异均有统计学意义（P＜0.05）。MIB-1和p27kip1表达与性别、年龄、病理分型、发病部位等均无相关性（P＞0.05），与临床分期存在相关性（P＜0.05）。MIB-1表达阳性患者中位生存时间低于阴性患者，而p27kip1表达阴性患者中位生存时间低于阳性患者（χ2=6.979、15.247，P=0.008、0.000）。结论:MIB-1表达增加和p27kip1表达降低与肾母细胞瘤的发生、发展、预后密切相关，临床应根据其表达情况进行针对性干预，以改善患者的预后。     

“龙虎交战”针法针刺八脉交会穴对偏头痛患者头痛天数及血清CGRP表达的影响＊

目的 观察“龙虎交战”针法针刺八脉交会穴对无先兆偏头痛（Migraine without aura，MO）患者头痛天数及外周血降钙素基因相关肽（Calcitonin gene related peptide，CGRP）表达水平的影响。方法 按照头痛程度将90例MO受试者区层随机分为治疗Ⅰ组、治疗Ⅱ组和对照组各30例。治疗Ⅰ组施以“龙虎交战”针法针刺八脉交会穴（外关和足临泣），治疗Ⅱ组施以平补平泻针法针刺八脉交会穴（外关和足临泣），对照组施以平补平泻针法针刺非经非穴点，每次留针30分钟，5次/周，共治疗20次。于治疗前、治疗结束4周后的随访分别记录三组患者头痛天数的变化情况以判定疗效，并采集患者治疗前、治疗结束4周后随访的肘部静脉血用ELISA法检测血清中的CGRP含量的变化。结果 ①各组治疗前患者的头痛天数无显著差异（Ｐ > 0.05），治疗Ⅰ组、治疗Ⅱ组和对照组治疗结束4周后随访的头痛天数较治疗前均显著降低（Ｐ < 0.05）；治疗Ⅰ组头痛天数的降低显著优于治疗Ⅱ组和对照组（Ｐ < 0.001），治疗Ⅱ组头痛天数的降低显著优于对照组（Ｐ < 0.05）；②3组治疗前CGRP的表达无显著差异，治疗Ⅰ组、治疗Ⅱ组治疗结束4周后随访CGRP的表达较治疗前均显著下降（Ｐ < 0.001），对照组治疗结束4周后随访CGRP的表达较治疗前差异无显著性（Ｐ > 0.05）；治疗Ⅰ组CGRP治疗结束4周随访的表达较治疗Ⅱ组和对照组均显著下降（Ｐ < 0.01），治疗Ⅱ组CGRP的表达较对照组显著下降（P < 0.01）。结论 ①八脉交会穴施以“龙虎交战”针法针刺能明显改善MO患者的头痛天数，同时降低MO患者血清CGRP的表达水平，这可能是针刺八脉交会穴治疗MO的机制之一；②非经非穴点的针刺效应无持续性，而八脉交会穴的针刺效应具有持续性；③八脉交会穴可以充分发挥复式针刺手法的治疗效应，提示我们在临床上治疗疾病时不仅要注意腧穴配伍，恰当的针刺手法更是提高临床疗效、事半功倍的关键。
