目的 探究长链非编码RNA SNHG12在乙肝病毒X蛋白(HBx)诱导肝癌发生过程中的作用。方法 把课题组构建的肝前体细胞14-19、EGFP-14-19、HBx-EGFP-14-19通过小鼠肝门静脉注射到体内;采用 qRT-PCR、Western blot 方法检测30 d,90 d,180 d,360 d小鼠肝脏组织及细胞模型中HBx、SNHG12以及下游调节基因的mRNA和蛋白表达情况;使用si-SNHG12干扰其表达,并通过CCK-8、划痕实验、transwell实验、流式细胞术观察其对体外表型影响;检测SNHG12及下游的 mRNA 和蛋白表达;HE染色观察小鼠肝组织切片。结果 qRT-PCR结果表明SNHG12、Notch1、Hes1在HBx-EGFP-14-19细胞及各时间段的小鼠肝组织中均上调(F=48.808,P<0.000 1;F=13.322,P<0.000 1);Western blot结果显示在HBx过表达细胞及动物模型中,受HBx诱导SNHG12表达升高后Notch1信号通路被激活,促凋亡因子Bax下调,抗凋亡因子Bcl-2上调,细胞周期因子CDK2和Cyclin E上调;抑制SNHG12表达后,qRT-PCR、Western blot实验结果显示SNHG12(t=22.746,P<0.000 1)及其上述基因表达均扭转,CCK-8实验显示细胞增殖受到明显抑制,流式细胞术检测显示细胞凋亡增多,划痕及transwell实验表明细胞迁移及侵袭减弱。结论 HBx通过上调SNHG12诱导Notch1表达,导致细胞增殖、周期和凋亡异常,从而促进肝癌的发生。

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.

目的 探讨康复护理路径早期功能训练对桡骨远端骨折LCP(锁定加压接骨板locking compression plate, LCP)内固定术后患者腕关节功能康复的影响。方法 对2014年5月—2016年6月住院80例桡骨远端骨折LCP 内固定术后患者分为对照组和观察组,每组各40例,对照组按桡骨远端LCP内固定术后护理措施进行护理,观察组患者在此护理基础上,制定术后功能康复护理路径,按功能康复护理路径对术后患者实施早期功能康复训练,随访评价两组患者患肢的组织肿胀、疼痛、骨折复位和腕关节功能康复效果。结果 疼痛评分:对照组在术后第3天~14天疼痛评分均高于观察组(P＜0.005);肿胀程度评分:对照组在术后第3天~7天肿胀程度评分均高于观察组,消肿速度比观察组慢(P＜0.001);腕关节的屈伸活动范围、握力和捏力比较观察组优于对照组(P＜0.001);腕关节复位优良率观察组95%高于对照组87.5%(P＜0.001)。结论 应用康复护理路径对桡骨远端骨折的LCP内固定术后患者进行早期腕关节功能康复训练,能减轻患者疼痛和局部软组织肿胀,减少并发症,提高术后患者康复质量。

Objective To investigate the early functional training of rehabilitation nursing path to the effects of distal radius fracture LCP (locking compression plate LCP) in patients after internal fixation of wrist joint function rehabilitation. Methods From May 2014 to June 2016, 80 patients with distal radius fractures were divided into control group and observation group(n=LCP), each with 40 cases. The control group was treated with nursing care of patients with distal radius LCP internal fixation. On the basis of nursing, the patients in the observation group were given rehabilitation nursing pathway, and the patients were followed up according to the rehabilitation path including evaluation of two groups of patients with fracture limb swelling, pain, fracture reduction and wrist joint function rehabilitation. Results Pain score: in the third days to fourteenth days pain score of the control group was higher than the observation group (P<0.005); Swelling degree score: swelling scores of the control group for the third days to seventh days after were higher than those in the observation group, the swelling reduced slowly (P<0.001); The wrist flexion range, grip and pinch strength compared to the observation group was better than the control group (P<0.001); The good rate of wrist joint reduction in the observation group (95%) was higher than that in the control group[(87.5%) (P<0.001)]. Conclusion The application of rehabilitation nursing path for patients with distal radius fracture after LCP internal fixation for early rehabilitation of wrist function may reduce the pain and local soft tissue swelling, reduce complications and improve the quality of postoperative rehabilitation.
