This paper expounds the connotation of doctor-patient communication and its importance in medical prac-tice, and points out the problems existing in the doctor-patient communication in practice. Based on this, advances the ESP teaching ideas, reform mainly from the following several aspects: first, the increase in oral English course arrange-ment class, small class teaching;secondly, on the oral English teaching mode reform, with school, learning, is unified. Once again, to reform on English spoken language teaching material use, both medical professional knowledge and English language skills. Finally, the reform on oral English teaching staff, improve English teachers' team.

Objective:To illustrate the role of miRNA-143 on the invasiveness of cervical cancer cells. Methods:MiRNA-143 mimics or inhibitor sequences were transiently expressed in the cervical cancer cells by liposome transfection. Transwell assay was ap-plied to test the invasive ability of cervical cancer cells after miRNA-143 over-expression or inhibition. Bioinformatics assay was used to predict the targets of miRNA-143. RT-qPCR and luciferase reporter assay were performed to detect the expression of MACC1 mRNA in the cancer cells. RT-qPCR was conducted to test the expression of miRNA-143 and MACC1 mRNA in 20 fresh primary cervi-cal cancer and their matched para-neoplastic tissues. Statistical analyses were performed to evaluate the association between the expres-sion of miRNA-143 and MACC1 mRNA in the 20 cases of cervical cancer. Results:Transwell assays revealed that the miRNA-143 over-expression inhibited the cell invasiveness, while miRNA-143 inhibition promoted the invasive ability of the cervical cancer cells. Bioinformatics analyses revealed that miRNA-143 could target the 3'-UTR of MACC1. Dual luciferase reporter assay confirmed that miRNA-143 can affect 3'-UTR sequence in MACC1 genes. RT-qPCR analyses indicated that the expression of MACC1 mRNA was ob-viously down-regulated after miRNA-143 over-expression, while significantly increased after the miRNA-143 inhibition. The migration in Caski/miRNA-143 inhibitor cells was obviously elevated after being transfected with MACC1 shRNAs. RT-qPCR analyses showed that the expression of miRNA-143 was obviously decreased in the cancer tissues compared with the normal tissues, while MACC1 mRNA was apparently decreased in cancer tissues compared with the normal ones. Statistical analyses revealed that miRNA-143 was negatively correlated with MACC1 mRNA in the 20 cases of cervical cancer. Conclusion:This study reveals that miRNA-143 is down-regulated in the cervical cancer tissues. MiRNA-143 may play an important role in the regulation of cell invasiveness by targeting MACC1 in the cervical cancer cells.

AIM: To observe the effect of hypoxia on cardiaomyocytes apoptosis and the role of ALDH2 in the process. METHODS: Cultured cardiomyocytes of neonatal rats were used. Hypoxia was imposed to the cardiomyocytes with or without daidzin pretreatment. ALDH2 activity was measured by the method of acetaldehyde metabolism. Apoptosis was measured by Hoechest 33324 staining, fluorescence activated cell sorting (FACS) and the DeadEnd~ TM fluorometric TUNEL system. RESULTS: ALHD2 enzyme activity in myocytes was inhibited by daidzin (24 h, 60 ?mol/L) without induction of apoptosis. When exposed to hypoxia, however, the apoptisis was significantly increased in the cells pretreated with daidzin compared to those without the pretreatment. CONCLUSION: The reduction of ALDH2 activity might increase the susceptivity of myocytes to apoptosis following hypoxia, suggesting a protective role of ALDH2 in hypoxia-induced myocardial injury.

Objective To investigate the epidemic factors of schistosomiasis in wetlands in Sichuan Province, so as to provide scientific evidence for the prevention and control of schistosomiasis in wetlands. Methods The artificial and natural wetlands were selected from Sichuan Province, and the relevant data regarding wetlands were collected. Routine snail survey, investigation on human morbidity due to schistosomiasis, snail diffusion experiments, questionnaire survey, determination of water infectivity and retrospective survey were conducted. Results In Sichuan Province, the mean densities of living snails were 0.003 snails/0.1 m² and 2.033 snails/0.1 m² in the upper and lower reaches of the Meiwan Reservoir wetlands, 0.08 snails/0.1 m² in the Jinyan Lake of Guanghan City, 0.21 snails/0.1 m² in Muhe River of Guanghan City, and 0.02 snails/0.1 m² prior to the construction of Qiong-hai wetland park in Xichang City in 2015. Artificial simulation experiments showed that the largest distance of snail diffusion in water was 2 000 m. There were 8.80% (41/466) of subjects that lived neighboring wetlands, worked in wetlands and visited wet-lands having infested water contact behaviors. A total of 690 sentinel mice were assigned, and no Schistosoma japonicum infection was detected in the 677 mice dissected. Retrospective survey showed that the construction of the Meiwan Reservoir caused the spread of schistosomiasis in Dailing County, and snails were found in the ditches entering the Jinyan Lake and in Jinyan Lake areas 5 years following the construction of the Jinyan Lake in Guanghan City, with S. japonicum -infected snails detected in the ditches entering the Jinyan Lake. Conclusions O. hupensis snails are found in some wetlands in Sichuan Province. Protection of wetlands and snail control with environmental improvements are recommended for the prevention of snail importation in natural wetlands, while in artificial wetlands, thorough snail control is recommended during the construction of the wetlands because of the likelihood of snail importation via water systems. In addition, both natural and artificial wetlands require long-term systematic surveillance of schistosomiasis.
