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.

The capacity to generate iaterleukin-2(IL-2)of,and autologous rosette forming cel-ls(ARFC)ratio of 46 cancer patients(29 nasopharygeal carcinoma,11 lymphoma and6 leukemia)were studied.A several important things have been found as follows:(1)There was a significant decrease in capacity of cancer patient peripheral blood mono-nuclear cells(PBMC)to generate IL-2 after being stimulated for 48 hr by PHA(18%,whencompared to controls;P0.05);(3)The cancer patient plasma could markedly inhibit IL-2 generation,but control plasmadid not.This result suggested that the patient plasma contain immunosuppressive fact-or(s)which can block IL-2 generation;(4)ARFC ratio in cancerpatients was greatlylower than that of controls(10% and 22% respectively;P

Objective: To develop a high performance capillary electrophoresis(HPCE) method for the impurity limit test of raw material of ciprofloxacin. Methods: An optimal method was established by studying on pH value, sampling time and other electrophoretic conditions. Results: The RSD of migration time was 0.23% and of the peak area was 2.49%. The limit of detection was 1.21 ?mol/L. The impurity profile and content was consistent with the dilution of sample concentration. Conclusion: HPCE method proves to be suitable for impurity limit test of raw material of ciprofloxacin. [

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.

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.

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.
