It is generally agreed that motivation is one of the most important factors influencing the students success or failure in learning a language. Motivation, according to Harmer, is an internal drive that encourages the learner to pursue a course of action(1983: 3). Expressed more colloquially, when students perceive an attractive goal that they wish to achieve, they may do whatever is necessary to reach it. Then they are strongly motivated.This article aims at introducing the classification teaching method into English teaching. Studies suggest that classification teaching method has positive effects on motivation.

In view of the fact that the Pharmaceutical Patent Law will be put into effect in China,the authors suggest that the development of new drugs in China should be relied mainly rather on creating than on copying. However,some of the effective drugs should be still modelled on foreign products. We should pay great attention to the research work on pharmaceutical preparations and the development of Chinese patent medicine, intermediates of preparation and reagents.

Objective:To develop a new nucleic amplication method for detection of Chlamydia trachomatis DNA by gap ligase chain reaction(G-LCR).Methods:A G-LCR DNA amplification assay that targeted the outer major membrane protein gene(omp1)of CT was established to detect CT infection.The sensitivity and specificity of a newly developed G-LCR test was examined by the use of highly purified elementary bodies (EBs).DNA fragments of different species and from other bacteria1 were detected with G-LCR and routine polymerase chain reaction (PCR).Results:Using G-LCR,DNA fragments of 54bp were amplified from five different species.The sensitivity could be improved to detect out 2 chlamydial elementary bodies.G-LCR detected ten-fold EBs than PCR.No signal was observed when C.pneumoniae and other bacteria were used as templates.Conclusion:G-LCR is sensitive,rapid and specific for detection of Chlamydia trachomatis.

Objective:To explore the relations between freshmen's self-identity status,personality characteristics and mental health status.Methods:188 new students were asked to complete the questionnaires of mental health scale and personality scale from the China college students mental health evaluation system,and eollnge students self- identity status scale.Results:①the most status of identity is achievement(43.1%),then the identity diffusion (30.9%);②male students in compare with female,were more likely in achievement status(60.7?13.8/53.9?11.4,P0.406);③the achieve- ment status had obvious negative correlation with depression,dependency(r=-0.17～-0.24),the diffusion status had obvious positive correlation with depression,social-withdrawal,and impulsion(r=0.15～0.34);④active,ac- commodating,tough-minded personality characteristics had obviously negative correlation with mental symptoms(r= -0.16～-0.56).Conclusions:encourage college students to form the achievement ego-identity status,to be ac- tive,accommodating and tough-minded,will be helpful for their psychological health.

Objective:To investigate the preventive effect of nalmefene on sufentanil-induced cough in the patients with general anesthesia. Methods:Eighty patients with general anesthesia were randomly divided into the control group and the nalmefene group. The nalmefene group was intravenously given 0. 25μg·kg-1 hydrochloric acid natrium nalmefene 5 minutes before the induction, and physiological saline with the same capacity was given in the control group. Cough number and intensity in one minute after the injection of nalmefene were observed, and the changes of hemodynamic indices such as the blood pressure, heart rate and pulse oxygen satura-tion before the anesthesia induction (T0), 1min after sufentanil injection (T1) and after the intubation (T2) were observed and com-pared between the groups. Results:The incidence rate of cough was 37. 5% in the control group and 0% in the nalmefene group, and the incidence rate and strength of cough in nalmefene group were both lower than those in the control group (P<0. 05). The hemody-namic parameters at T1 showed notable changes when compared with those at T0 in the control group (P<0. 05), and had significant differences when compared with those in the nalmefene group (P<0. 05), and at T2, all the parameters recovered to the levels at T0. The parameters in the nalmefene group were much more steady than those in the control group (P>0. 05). Conclusion:Pretreatment with hydrochloric acid natrium nalmefene can prevent sufentanil-induced cough response during the induction of anesthesia without weakening the inhibitory effect of sufentanil on intubation response.

The clinical medical work is accompanied with high risk .The medical treatment risk exists everywhere at anytime, but the graduate students of the Medical colleges lack the understanding of the hygiene laws. Therefore it is necessary for them to accept the education of hygiene law.

To solve the problems occurring in Ophthalmologic clinical teaching,we made a detailed investigation on the idea,mode as well as the application of specific methods for ophthalmologic clinical teaching.Then we raised a further proposition compatible with the social environment in order to improve the efficiency and quality of ophthalmologic clinical teaching.

Self-directed learning(SDL)is an important learning form for the future educational development and the continued medical education.SDL facilitates the learning effects of advanced studying doctors in neonatology.This article investigates the major developments and influencing factors relative to self directed learning,and provides insight into the practice and progress of self directed learning of the advanced studying doctors in neonatology.
