The bilingual teaching of genetic engineering is of great necessity for undergraduates,because it facilitates students to better understand the basic concept,improve their English level,increase their expertise,and promote their ability to solve problems in their studies.To achieve this goal,it is advised that the strategies such as selection of good textbook,the preparation of high quality teaching materials,the increase in teaching capability for teachers,class discussion and course examination in English are rather effective.

Immunocytochemistry, flowcytometry and nucleic acid in situ hybridization were used to observe the effect of sodium tanshinon Ⅱ-A silate (DS201) on proliferation of pulmonary artery smooth muscle cell (PASMC) induced by hypoxic endothelial cell condition medium (HECCM). The results showed that DS201 could obviously hinder PASMC to enter S phase from G0/G1 phase (P<0.05), and decrease the expression of PCNA and platelet-derived growth factor (PDGF)-A and B chain mRNA in PASMC respectively, (P<0.01). It was suggested that DS201 could probably inhibit the prolifertion of PASMC mediated by HECCM, through down-regulating the expression of PDGF-A and B chain gene.

HIV/AIDS has posed an increasingly serious issue in China. In recent years, Chinese government has taken further intensified efforts to combat HIV/AIDS with high-level political commitment, supportive policy development, increased financial allocation, large-scale of governmentled initiatives, expanded international cooperation and great involvement of non-governmental organizations. Meanwhile gaps and challenges coexist impacting the implementation and the results of national HIV/AIDS programs. Thus, further government efforts are needed to improve and tailor the actions to meet the requirement of HIV/AIDS control in China.

Assisted reproductive technology causes a probable rise of artificial multi-embryo.This paper deeply analyzes the ethnical problems brought by it,and makes some corresponding countermeasures.

1 ?mol/L,24 h); (3) With the development of neoplastic transformation, the resistance to terminal differentiation induced by some promoter increased till the promoter became mitogenic. Conclusion: The development of transfected cells provides a powerful and convenient model for detecting potential tumor promoters and research on the mechanisms of promotion tumor.

Objective To explore the psychology of anxiety neurosis and drug treatment efficacy.Methods 123 clearly diagnosed anxiety neurosis sufferers were randomly divided into group A(psychotherapy),group B(drug treatment) and group C(psychotherapy and drug treatment).Psychological measuring scale SCL-90 was adopted and the results were compared at pretreatment and at 8 weeks post-treatment.Results Anxiety neurosis was often accompanied with apprehensiveness,depression,personal relationship sensitivity,compulsion and somatization.Therapeutic efficacy of group C was the best and the symptom remission rates were group A 43.9%,group B 57.5% and group C 88.6%.The rate of group C was significantly different compared with those of group A and group B(P0.05).Conclusion Though drug intervention is necessary,psychotherapy and drug treatment are the best regimens of therapy for anxiety neurosis.

Objective To explore the relationship between the sperm DNA integrity and ART result.Methods Employ improved SCD test for sperm DNA integrity assay.Meanwhile,statistical methods was used for data analysis.Results After compaed the infertility rate( IVF:77.4％ vs 84.8％,P =0.366;ICSI:90.1％ vs 92.1％,P =0.899),cleavage rate ( IVF:97.1％ vs 96.4％,P =0.958 ; ICSI:96.0％ vs 99.0％,P =0.845 ),high-quality embryo rate ( IVF:42.8％ vs 38.6％,P =0.485 ; ICSI:25.8 ％ vs 46.2％,P =0.002 ) and pregnancy outcome ( IUI:13.8％ vs 16.6％,P =1.000;IVF:35.3％ vs 73,7,P =0.150;ICSI:49.5％ vs 42.8,P =0.832) between the populations with normal and abnormal sperm DNA integrity during ART therapy,there is no statistical difference was found except high-quality embryo rate with ICSI therapy.Conclusion Sperm DNA integrity value can't be used to predict the ART outcomes independently.

Autoimmune pancreatitis (AIP)is a special type of chronic pancreatitis that originates from an autoimmune -mediated mecha-nism.AIP has unique radiological,serological,and histopathological features,often accompanied by peripancreatic lesions.AIP may be easily confused with pancreatic cancer and cholangiocarcinoma.It is necessary to diagnose AIP while integrating a variety of clinical indica-tors.Steroid therapy should be performed for patients diagnosed with AIP,and surgical treatment can be selected if necessary.

Objective To investigate the clinical effect of psychological intervention combined with insulin, glimepiride in the treatment of patients with diabetes mellitus. Methods 60 cases of patients with diabetes treated in our hospital from January 2015 to January 2017 were divided into two groups.The control group was treated with routine nursing intervention and insulin treatment, the observation group was treated with psychological intervention+insulin+glimepiride therapy; The clinical efficacy and clinical symptoms in the two groups were compared. Results The clinical effect of the observation group was better than that of the conventional control group,the clinical symptoms improved was better than the control group, the difference was statistically significant (P<0.05). Conclusion The clinical effect of psychological intervention+insulin+glimepiride in the treatment of diabetes is significantly, can effectively improve the clinical symptoms of patients, is widely used in clinical treatment of patients with diabetes.
