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.

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.

目的观察膝关节置换术后功能锻炼和康复指导对减少术后并发症、尽早恢复关节功能、提高患者术后生存质量的作用。方法对23例(26膝)膝关节置换术后患者进行早期主动和被动功能锻炼,预防关节屈曲挛缩和下肢深静脉栓塞。结果经平均13个月随访,23例患者的优良率达85.8%。结论膝关节置换术后进行早期康复训练可减少术后并发症,尽早恢复关节功能,并获得长期稳定的疗效。

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.

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.

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.

The application of standardized patien(tSP)has not been widely used in China. This article summarized some experiences of using SP in pediatric clinical teaching such as choice and training SP,the writing of scenario,and the score criterion in OSCE. We concluded that the use of SP had irreplaceable advantages.
