Objective In order to explore the role of long non-coding RNA SNHG12 in hepatitis B virus X protein (HBx) induced hepatocarcinogenesis. Methods The liver precursor cells 14-19, EGFP-14-19 and HBx-EGFP-14-19 constructed by the research group was injected into the body through the hepatic portal vein of KM mice; qRT-PCR and Western blot were used to detect the mRNA and protein expression of HBx, SNHG12 and downstream regulatory genes in liver tissues of 30 d, 90 d, 180 d and 360 d mice and cell models. Si-SNHG12 was used to interfere with SNHG12 expression in vitro, the mRNA and protein expression of SNHG12 and downstream genes were detected, and its effect on phenotype in vitro was observed by CCK-8, flow cytometry, scratch test and transwell test. HE staining was used to observe the liver sections of mice. Results qRT-PCR showed that SNHG12, Notch1 and Hes1 were up-regulated in HBx overexpression cells and mouse liver tissue at each time point (F=48.808,P<0.000 1;F=13.322,P<0.000 1); the results of Western blot showed that in HBx over-expressing cells and animal models, the expression of SNHG12 was increased induced by HBx, resulting in the activation of Notch1 signal pathway, the down regulation of pro-apoptotic factor Bax, anti-apoptotic factor Bcl-2, and the up-regulation of cell cycle factors CDK2, cyclin E. After inhibiting the expression of SNHG12, the results of qRT-PCR and Western blot showed that SNHG12 (t=22.746,P<0.000 1) and the above genes were inhibited; CCK-8 experiment showed that cell proliferation was significantly inhibited, flow cytometry showed that cell apoptosis increased, scratch experiment and transwell experiment showed that cell migration and invasion decreased. Conclusions HBx induced Notch1 expression by up regulating SNHG12, resulting in abnormal cell proliferation, cycle and apoptosis, so as to promote the occurrence of liver cancer.

临床研究中,我们会经常遇到多重检验的问题。当同时检验多个假设时,如何控制犯Ⅰ类错误的概率,保证结果的准确性,是研究者面对的首要问题。然而未对多重检验进行校正的文章比例仍较大。本文从简单的单个检验假设出发,回答为什么需要进行多重校正,何时进行多重校正,同时介绍总体错误率(FWER)和错误发现率(FDR)两种重要的错误率以及在此基础上的Bonferroni和Benjamini-Hochberg校正方法,从而避免因多重检验问题带来的混乱。

In clinical research, we often encounter the problem of multiple testing. When testing many hypotheses at the same time, how to control the type I error to ensure the accuracy of the results is the primary problem faced by researchers. However, the proportion of articles that didn't correct the multiple testing remains substantial. Starting with the simple hypothesis of a single test, this article provides an introduction to multiple testing issues, answers why and when multiple corrections are needed, introduces two important error rates which are family-wise error rate (FWER) and false discovery rate (FDR), and the Bonferroni and Benjamini-Hochberg correction methods based on them, thereby avoiding confusion caused by multiple testing.

Objective To explore the cause of hoarseness of voice in patients after thyroidectomy with recurrent laryngeal nerve exposure. Methods The patients from January 2019 to December 2020 underwent thyroidectomy with exposure of recurrent laryngeal nerve during operation were selected. There were 19 cases of hoarseness of voice after operation followed up for 12 months. Postoperative observations included the characteristics of the hoarseness of voice, duration, and direct laryngoscope neck ultrasonography. Results A total of 19 patients had voice hoarseness, only 5 of them had recurrent laryngeal nerve injury during operation, the other 14 patients had good exposure and protection of recurrent laryngeal nerve. Direct laryngoscope showed that 4 of 14 patients had vocal cord edema and 1 had subluxation of arytenoid cartilage. About 1 week after operation, ultrasound examination showed that 11 of 14 patients had varying degrees hydrops of wound cavity. Conclusions Although the routine exposure of recurrent laryngeal nerve reduces the incidence of postoperative hoarseness of voice, the injury of recurrent laryngeal nerve is still a cause of postoperative hoarseness of voice. In addition, non-operative direct factors, such as fluid accumulation in the operative field, vocal cord injury caused by anesthetic intubation and other intubation related complications, are also important reasons for postoperative hoarseness of voice in these patients, which we should pay more attention to.
