OBJECTIVE To investigate the effect of microRNA-129(miR-129)expression on malignant phenotypes of esophageal squamous cell cancer(ESCC) cells and its possible molecular mechanisms. METHODS The constructed miR-129-overexpressed vector (pGCMV/EGFP/miR-129) and negative control vector (pGCMV/EGFP/miR-NC) were stably transfected into ESCC cell lines (Eca109 and EC9706),respectively. Quantitative real-time PCR(qRT-PCR)was performed to detect the expression of miR-129. MTT and flow cytometry(FCM)assays were performed to analyze the effects of miR-129 on proliferation, cell cycle and apoptosis of ESCC cells. Furthermore,a luciferase reporter vector with the putative B-cell lymphoma-2(Bcl-2)3′-untranslated region(pLUC/Bcl-2-3′-UTR-wt and pLUC/Bcl-2-3′-UTR-mut)was constructed to explore whether Bcl-2 was a direct target gene of miR-129 by detecting luciferase activity. Next,Western blotting was performed to detect the expression of Bcl-2, cleaved caspase 3 and total caspase 3 proteins. RESULTS Overexpression of miR-129 significantly inhibited proliferation(P<0.01),induced cell arrest in G0/G1 phase(P<0.05)and enhanced apoptosis (P<0.05)in ESCC cells. Luciferase reporter assay indicated that Bcl-2 was identified as a direct target gene of miR-129. Results of Western blotting showed that overexpression of miR-129 significantly reduced the expression of Bcl-2 protein and increased the expression of cleaved caspase 3 protein,but induced no changes in total caspase 3 protein in ESCC cells. CONCLUSION miR-129 functions as a tumor suppressor in ESCC cells by targeting Bcl-2 gene. Therefore,miR-129 will be a potential molecular target for the treatment of human ESCC.

Objective To compare the safety and efficacy of intravenous thrombolysis for patients with acute cerebral infarction in a second-grand class-A hospital and a third-grand class-A hospital. Methods Twenty-one consecutive patients with cerebral infarction treated with alteplase for intravenous thrombolysis were enrolled in a second-grand class-A hospital (Fengtai Hospital,Beijing)prospectively from January 2012 to December 2013 as the study group,and 65 patients in a third-grand class-A teaching hospital (Xuanwu Hospital,Capital Medical University,Beijing)admitted at the same period for intravenous thrombolysis were used as a control group. The differences of efficacy and safety of intravenous thrombolysis in patients of both groups were compared. The primary outcome measures were Barthel Index (BI)at day14 after onset and the modified Rankin Scale (mRS)scores at discharge. The main safety indicator was the incidence of serious adverse events (SAEs)after thrombolysis (symptomatic intracranial hemorrhage and death). Results (1 )In the primary outcome measures,the proportions of mRS≤2 at discharge in the study group and the control group were 71. 4%(n=15)and 58. 5%(n=38)respectively. At day 14 after thrombolysis,the proportions of BI ≥60 were 61. 9%(n=13)and 64. 6%(n=42)respectively. There were no significant differences between the two groups (P>0. 05). (2)The incidences of the primary serious adverse events were 4. 8%(n=1)and 6. 2%(n=4). There was no significant difference (P>0. 05). Other secondary outcome measures,such as the early reperfusion rate,recanalization rate,and the proportion of neurological improvement at day 14 after thrombolysis and the overall incidence of cerebral hemorrhage had no significant differences. The case referral proportion (9. 5%,n=2)of the study group had a trend of lowering than the control group (27. 7%,n=18)P=0. 09. (3)The out-hospital time delay, in-hospital time delay,and overall time delay of the study group were less than those of the control group, and the mean time was 75 ± 33 vs. 102 ± 50 min,and 72 ± 41 vs. 111 ± 38 min,147 ± 41 vs. 212 ± 47 min. There were significant differences (P<0. 01). Conclusion The second-grand hospital selected by our study can relatively safely and effectively perform intravenous thrombolysis for acute cerebral infarction with alteplase. Moreover,the intravenous thrombolysis of the second-grand hospitals may reduce the case referral ratio and visiting time.

objective To investigate the recurrence of stroke,clinical prognosis and vascular changes in patients with ischemic stroke due to middle cerebral artery stenosis. Methods The ischemic stroke patients with symptomatic middle cerebral artery stenosis were enrolled continuously and followed up prospectively for six months. The recurrence of ipsilateral stroke,clinical prognosis and dynamic changes of vessels were analyzed. Results Eighty patients were included,and 20.0% of the patients(16 cases)presented with recurrence of ipsilateral ischemic stroke and 56 cases (70.0%)with a good outcome(modified Rankin scale[mRS]≤1)during the 6 months follow-up;38.6% patients (27 cases) presented with significant vascular changes with progression in 12 cases (17.1%)and regression in 15 cases (21.4%). Conclusion The patients with simple symptomatic middle cerebral artery stenosis have an high rate recurrence of ipsilateral stroke but have good prognosis;Lesioned artery of the majority of patients in the short period after stroke was stable,but vascular stenosis in some patients could appear progression or remission.

Background and purpose:Although intermittent endocrine therapy is a treatment strategy for new patients with advanced prostate cancer, the use of hormonal therapy is still controversial. This study aimed to investigate the efficacy of intermittent hormonal therapy for the patients with advanced prostate cancer and determine the factors influencing efficacy of the treatment.Methods:From Jul. 2009 to May 2015, patients with advanced prostate cancer were treated with 6 months of hormonal therapy, and then efficacy was assessed. A hundred and twenty-eight hormone sensitive patients were randomly divided into intermittent and continuous treatment groups, and were observed with efficacy, side effects, quality of life scores and other indicators. The prognostic factors for intermittent group were analyzed.Results:A total of 128 patients with advanced prostate cancer were enrolled in the study. Prostate-specific antigen (PSA) levels were significantly decreased in 96 patients after endocrine therapy. Among those, 43 patients received intermittent endocrine therapy while 53 patients received continuous endocrine therapy. The score of KPS in the intermittent treatment group was 82.6±7.4, which was significantly higher than that of the continuous group (KPS score was 69.8±8.7). There was a sig-nificant difference between them (P<0.05). The incidence of treatment related side effects and the proportion of developing hormone independent tumor in the intermittent group were significantly lower than that in the continuous treatment group (P<0.05). The 5-year survival rate in intermittent group was 72.1%, higher than that in the continuous group (63%). How-ever, the difference was not statistically significant (P>0.5). PSA level in the early stage of endocrine therapy and G1eason score before treatment were important factors affecting the prognosis of patients. The patients in the intermittent group were followed up for 13-70 months, and received 1 to 4 cycles of treatment. The number of patients in the treatment was declined during the extension of the treatment, and the treatment interval was shorter.Conclusion:Intermittent endocrine therapy is an effective treatment for advanced prostate cancer. It is safe and reliable. It can improve the quality of life for patients and reduce the economic burden on them.

Objective To introduce the procedures and evaluate the clinic value of CT-guided interstitial 125I seeds implantation in treating lung cancer. Methods Thirty-one cases patients with lung cancer underwent CT-guided interstitial 125I seeds implantation. All patients were scanned on multi-spiral CT (Philips, MX 8000) with optical navigating system (pinpoint), and treatment plan system, needle, and 125I seeds (Chinese Academy of Science) were used. First of all, according to the size of tumor, TPS calculated the optimal quantity of seeds. Then, under the guidance of CT, 125I seeds were percutaneously implanted into the tumors for interstitial radiotherapy. CT follow-up examinations were performed 1, 2, and 6 months after the therapy, respectively. According to the size of tumor, curative effects were graded as 4 grades: grade Ⅰ: obvious relief (OR) (the size of tumor reduced up to 50%), grade Ⅱ: relief (PR) (the size of tumor reduced by 25%-50%), grade Ⅲ: slight relief (SD) (the size of tumor reduced by 1%-25%), and grade Ⅳ: no effect (PD) (the size of tumor did not reduce or increase, and clinic symptoms showed no relief). Results At 1 month, 9 cases were classified as grade Ⅰ, 6 as grade Ⅱ, 13 as grade Ⅲ, and 3 as grade Ⅳ, respectively. At 2 months, 17 cases were grade Ⅰ, 8 grade Ⅱ, 3 grade Ⅲ, and 3 grade Ⅳ, respectively. At 6 months, 23 cases were grade Ⅰ, 3 grade Ⅱ, 2 grade Ⅲ, and 3 grade Ⅳ, respectively. Conclusion CT-guided interstitial 125I seeds implanted was a safe, reliable, and effective curative method for lung cancer.
