Objective To explore the influencing factors on short -term efficacy of intravenous thrombolysis with rt -PA.Methods The clinical data of the 95 acute ischemic stroke(AIS)patients who received thrombolytic therapy were analyze.Multivariate logistic regression analysis was used to determine the possible influencing factors. Results Fifty -six(58.95%)patients had favourable outcomes after thrombolytic therapy for 24 hours.Multivariate logistic regression analysis indicated that diabetes(OR =3.933,95% CI 1.199 ~12.897)and TOAST classification (OR =1.448,95% CI 1.032 ~2.032 )were the independent predictors of short -term outcome.Conclusion Diabetes and TOAST classification are the major influencing factors of short -term efficacy after intravenous thrombolysis with rt -PA.It should pay attention screening patients for intravenous thrombolysis therapy and predicting the efficacy of thrombolysis.

Objective:To investigate the effect of lentivirus-mediated silencing of mitochondrial ribosomal protein L35 (MRPL35) gene on the growth of human esophageal cancer TE-1cells, and to clarify its mechanism.Methods:Three kinds of human esophageal cancer cells, TE-1, ECA109and KYSE150, were selected.The relative expression levels of MRPL35mRNA in three kinds of cells by real-time quantitative PCR.The esophageal cancer TE-1cells were divided into shMRPL35group and shCtrl group, and the cells were infected with si-RNA lentivirus and si-RNA lentivirus;the esophageal cancer cell line stably silenting the MRPL35gene was established.Real-time quantitative PCR and Western blotting methods were used to detect the efficiency of MRPL35gene silencing.The cell growth curves in various groups were detected by CCK-8method, and the apoptotic rates were detected by flow cytometry after AnnexinⅤ-PE/7AAD double staining.Results:Three kinds of esophageal cancer cells expressed MRPL35gene, and the expression levels were not statistically significant between them (P＞0.05) .The results of real-time quantitative PCR and Western blotting methods showed that the mRNA and protein levels of MRPL35in the TE-1cells in shMRPL35group were significantly lower than those in shCtrl group (P＜0.05) .Compared with shCtrl group, the cell growth speed in shMRPL35group was decreased (P＜0.05) , and the apoptotic rate was significantly increased (P＜0.01) .Conclusion:Silencing MRPL35gene can inhibit the proliferation of esophageal cancer TE-1cells and plays a role through the apoptotic pathway.

Objective:To compare the dosimetry and efficacy of intracavitary brachytherapy (ICBT) and intracavitary/interstitial brachytherapy (IC+ ISBT) based on CT image guidance in the treatment of stage Ⅲ B cervical cancer. Methods:Clinical data of 93 patients with stage Ⅲ B cervical cancer treated in Department of Radiotherapy of Jilin Cancer Hospital from June 2014 to February 2017 were analyzed retrospectively. According to the results of Gynecological examination and pelvic MRI before brachytherapy, confirming the size of residual tumor and the degree of parauterine infiltration, all patients were divided into the ICBT and IC+ ISBT groups. The D 90%, D 100%, V 100% and D 2cm 3 of bladder and rectum were compared, and the short-term and long-term efficacy was observed between two groups. Results:The median follow-up time was 60 months. The 5-year local control rate, distant metastasis-free survival rate and overall survival rate of all patients were 83%, 71% and 68%, respectively. Compared with the ICBT group, HR-CTV D 90% in the IC+ ISBT group was all more than 85 Gy, while there was no significant difference between two groups ( P=0.188). The D 2cm 3 of bladder and rectum in the IC+ ISBT group was significantly decreased by 7 Gy and 8 Gy (both P<0.01), and the distant metastasis-free survival rate was significantly improved ( P=0.009). The 5-year local control rate in the HR-CTV volume>60 cm 3 in the IC+ ISBT group was significantly higher than that in the IC group ( P=0.029). Conclusion:For patients with Ⅲ B cervical cancer, IC+ ISBT can not only ensure target coverage, but also significantly reduce the incidence of distant metastasis and the dose of organs at risk, and significantly improve the local control rate of large tumors.

Objective: To investigate the curative effect and prognostic factors of radical radiotherapy for cervical cancer. Methods: A total of 211 patients with stage Ⅰ_A-Ⅲ_B cervical cancer who underwent therapy in department of radiotherapy, Tumor Hospital of Jilin province between June 2014 and February 2017, were analyzed retrospectively. All patients received radical radiotherapy with or without concurrent chemotherapy. Short-term and long-term efficacy and related prognostic factors were observed. Kaplan-Meier method was used for survival analysis, Log-rank test was used for univariate analysis, and Cox proportional hazards regression model was used for multivariate analysis. Results: The 2-year overall survival (OS) and disease free survival (DFS) were 83.4% and 72.5%, respectively. During the follow-up periods, 46 patients (21.8%) died, including two from non-tumor-related diseases, and one from second primary colon cancer. Totally 57 patients (27%) had recurrence and metastasis, including 16 (28.1%) with local recurrence, 27 (47.4%) with distant metastasis, and 14 with local recurrence and distant metastasis(24.6%). Univariate analysis showed that 2-year OS and DFS were significantly correlated with pathological type, pre-treatment squamous cell carcinoma antigen (SCC) value and FIGO stage (OS: χ²=7.123, 6.014, 8.398, P<0.05; DFS: χ²=11.832, 8.003, 7.731, P<0.05). In addition to the above factors, 2-year DFS was also associated with pelvic lymph node metastasis (χ²=9.286, P<0.05). Multivariate analysis showed that pathological type, pre-treatment SCC value and FIGO stage were independent prognostic factors of OS(HR=2.963, 2.473, 2.574, P<0.05). The independent prognosis factors affecting DFS included pathological type, pre-treatment SCC value and pelvic lymph node metastasis (HR =3.014, 1.988, 1.914, P<0.05). Conclusions By means of radical radiotherapy, cervical cancer patients with adenocarcinoma, pre-treatment SCC levels ≥30 ng/ml and advanced stage have poor prognosis, so more active treatment strategy should be adopted.

Intestinal injury is a common adverse reaction of clinical chemotherapy drugs, which limits the further application of chemotherapy drugs and causes serious physical and mental burden to patients. At present, the mechanism of chemotherapy-induced intestinal injury is complex, and traditional Chinese medicine has an excellent preventive effect. This article reviews the related mechanisms of intestinal flora imbalance, oxidative stress, inflammatory response, cell apoptosis, and immune damage caused by chemotherapy, and summarizes the role of traditional Chinese medicine in prevention and treatment of oxidative stress, inflammatory response, cell apoptosis, and immune damage.
