Objective: To explore the effect of previous treatment on the efficacy of multidrug resistant pulmonary tuberculosis (MDR-TB) patients. Methods: From February 2015 to February 2017, 64 cases with MDR-TB who received treatment in the First Hospital of Ninghai were collected.All patients received antituberculous therapy for 6 months.The clinical data were retrospectively analyzed.The factors that influence the efficacy of MDR-TB patients were evaluated by multivariate logistic regression analysis. Results: After standard chemotherapy for MDR-TB patients, the incidence of chest radiographic lesions in primary and relapsed MDR-TB patients was 18 cases(81.82%) and 21 cases(50.00%), respectively.There was statistically significant difference between the two groups (χ²=22.835, P<0.05). The cavity closure rate of MDR-TB patients after primary treatment and relapse was 54.55% and 40.48%, respectively, and there was significant difference between the two groups (χ²=8.693, P<0.05). After standard chemotherapy for MDR-TB patients, the cure rates of primary and recurrent MDR-TB patients were 18 cases(81.82%) and 23 cases (54.76% ), respectively, there was statistically significant difference between the two groups (χ²=21.791, P<0.05). Conclusion The effect of initial treatment of MDR-TB is better than recurrent MDR-TB, so it is necessary to strengthen the surveillance of drug resistance in patients with tuberculosis and to find the disease as soon as possible.Early treatment of MDR-TB is the best option for patients.

Objective To evaluate the practical efficacy of comparison method in experimental teaching of pathological anatomy.Methods The junior college students of stomatology were divided into experimental group (n =48) and control group (n =48) randomly.Students in experimental group adopted the experimental teaching with comparison method of pathological anatomy and histology while those in control group followed the traditional experimental teaching.Experiment examination results of two groups were compared and questionnaire investigation was carried out among students in experimental group.Results Average score of experiment examination in experimental group was (88.35 ±5.68) while that in control group was (78.35 ±4.86),with statistical differences (P ＜0.01).The results of questionnaire investigation showed that students in experiment group preferred comparison teaching method.Conclusions Comparison teaching method is feasible,the mechanism of which emphasizes gaining new knowledge by reviewing the old and strengthens the contact of basic subjects,therefore it is conducive to enhancing the quality of pathological experimental teaching.

Next-generation sequencing has allowed identification of millions of somatic mutations in human cancer cells. A key challenge in interpreting cancer genomes is to distinguish drivers of cancer development among available genetic mutations. To address this issue, we present the first web-based application, consensus cancer driver gene caller (C), to identify the consensus driver genes using six different complementary strategies, i.e., frequency-based, machine learning-based, functional bias-based, clustering-based, statistics model-based, and network-based strategies. This application allows users to specify customized operations when calling driver genes, and provides solid statistical evaluations and interpretable visualizations on the integration results. C is implemented in Python and is freely available for public use at http://drivergene.rwebox.com/c3.
