Background and purpose:In recent years, the studies have indicated that long non-coding RNAs (lncRNAs) may play important roles in the initial stage and development of tumors. H19 is one of those lncRNAs, which is already proved to overexpress in a variety of tumors such as bladder cancer, stomach cancer and hepatocellular carcinoma (HCC). And H19 also could promote tumor proliferation and increase tumor cell migration and invasion ability, but neither the expression nor the function of H19 in non-small cell lung cancer(NSCLC) are clariifed. This study aimed to observe the effects of H19 on the proliferation, epithelial-mesenchymal transition (EMT) and invasion ability of NSCLC cell line A549.Methods:H19 was overexpressed by plasmids transfection, then the effect of H19 on the proliferation of A549 was measured by cell counting kit-8(CCK-8), the invasion of A549 cells was detected by Transwell assay, and the changes of cell morphology were observed with an optical microscope, and the expression of EMT-related proteins was detected by Western blot, and the promoter activity of CDH1 was measured by luciferase assay.Results:The proliferation of A549 cells was increased under the overexpression of H19(D value in blank group was 1.64±0.02, in negative control group was 1.59±0.04, in overexpression of H19 group 1.89±0.02,P<0.05), the invasion ability of A549 cells was dramatically enhanced [negative control group (30±6)/vision, overexpression of H19 group (110±7)/vision,P<0.05], and the A549 cells developed longer pseudopodia and had wider intercellular spaces. All these morphology changes indicated that the cells were undergoing the process of EMT, and meantime, the expres-sion of CDH1 was decreased, along with the expression of VIM and SNAI2 elevated, which were also related to the progression of EMT, and H19 also could depress the promoter activity of CDH1 by 60% (P<0.05).Conclusion:The overexpression of H19 induces the EMT, and enhances the proliferation and invasion ability of A549 cells.

Background The clinical efficacy and safety of mouse nerve growth factor(NGF) for injection have been evaluated by Ⅰ,Ⅱ,Ⅲ stage of clinical trials.But as a clinical drug,its adverse effects for special population should been further studied.Objective This clinical trial was to observe and assess the safety and tolerability of mouse NGF for injection during the application in juvenile and elder patients with optic nerve damage.Methods A multicenter non-randomized controlled trial for the safety evaluation of mouse NGF injection solution was performed in 100 eye centers in China.This study protocol was approved by the Ethic Committee of each drug research center,and written informed consent was obtained from the subject,legal mandatary and guardian prior to this study.Total 2046 patients who met the included criteria of optical nerve damage were enrolled.The patients were divided into the juvenile group(90 cases,＜ 18 years),youth-middle-age group (1868 cases,1 8-75 years) and older group(88 cases,＞75 years).Mouse NGF(30 μg)was intranuscularly injected once per day for 21 days in all the patients.Systolic and diastolic blood pressure,heart rate,intraocular pressure (lOP),laboratory examinations of blood and urine,blood biochemical indexes were recorded before and after injection.All adverse events were evaluated after administration of drug.Results There were 189 (189/2046,9.23％)dropped out cases,including 184 lost cases after 3 weeks of treatment and 5 withdrew cases from adverse responses of drug,with a shedding rate ＜10％ in each group.Total 1857 individuals finished this trial.No significant differences were found in the IOP,heart rate and blood pressure between before and after admninistration of grug in the juvenile group,youth-middle-age group and older group (P＞0.05).The incidence rate of the adverse response in the juvenile group,youth-middle-age group and older group was 57.78％,68.18％,60.01％ respectively,and the primary local adverse events were pain(48.89％),redness and swelling(59.09％),duration(54.49％),without significant difference in the rate of local adverse events among the three groups(X2 =2.302,P =0.324).The abnormal rates of laboratory results of blood and urine were not significantly different among the three groups(all at P＞0.05).The percentage of impaired fasting glucose was 7.46％,23.73％and 7.79％ in the juvenile group,youth-middle-age group and older group,respectively,and the percentage in the older group was higher than that in the juvenile group and the youth-middle-age group (x2 =8.685,P =0.005 ;x2 =27.720,P =0.000).Conclusions Injection of mouse NGF is well tolerated in juvenile and elder patients over the age of 75 years.

Aim To further study the protective effects of acutobin on focal cerebral ischemia -reperfusion injury in rats. Methods Reversible middle cerebral artery occlusion (MCAO) models were produced by intraluminal suture technique, and reperfusion was begun 3 hours after occlusion and lasted 24 h. The extent of neurological deficits was evaluated by Longa' method; The cerebrovascular morphology was observed by electron microscope. The infarct area of brain was measured by 2,3,5-triphenyltetrazolium chloride (TTC) staining technique;The 2～4 U?kg~(-1) doses of Acutobin were administrated i.v. at the beginning of ischemia or reperfusion respectively. Results ① After 3-h occlusion and 24 h reperfusion, the neurological syndromes and the infarct area were showed, the change of cerebrovascular morphology were appeared and the ratio of TXB_2/6-Keto-PGF_(1?) in plasma was increased. ② After different doses of acutobin were administrated at different time respectively, the neurological syndromes were alleviated; the infarct areas of brain were diminished; the hurt of cerebrovascular endothelial cell was lessened and the ratios of TXB_2/6-Keto-PGF_(1?) in plasma were reduced. Conclusion Protective effects of acutobin on cerebral ischemia-reperfusion injury in rats may be related to lessening cerebrovascular injury and balancing the ratio of TXB_2/6-Keto-PGF_(1?)
