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.

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.

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 explore ladder and compensation system of nurse-staffing which is suitable for the situation of our country.Methods The ladder management and compensation system to nursestaffing of National Health Service (NHS) in UK were given detailed introduction and analysis through the official documents,references and personal study experiences,and summarize its scientific and referenced aspects.Results NHS has formed a set of mature competency-based ladder system,and linked the ladder system to compensation system,made a relative scientific performance appraisal system,realized the scientific competency matches the level,salary changes along with the level model.Conclusions It provides references and thinking to the in-depth reform of public hospitals in our country,and the development of high quality nursing service,as well as the implementation of nursing ladder management and compensation reform.

Objective To investigate the clinical effect of plastic surgery of double-palpebra with reposition of lacrimal gland for blepharochalasis.Methods We operated on 10 cases (20 eyes) with dermatolysis palpebrarum which stopped attack and was static for more than one year.A double eyelid fold incision was made.Then redundant skin and sphincter palpebrarum as well as protrusion of intraorbital fat were removed.In the operation of dislocation of lacrmial gland we sewed up lacrmial gland in full thickness and fixed it to the periosteum of lacrmial fossa,and the levator muscle of upper eye lid aponeurosis prothesis or plication was choosed when the levator muscle of upper eye lid aponeurosis was broken or not.And for the shorted transverse diameter of coloboma of eye lid we sewed up the external palpebral ligament and fixed it to the periosteum of lateral orbital margin.Results All the 10 patients got satisfactory therapeutic effect,the cutis laxa had been amended obviously,the good upper double eyelid shape could be achieved,the reposition of lacrimal gland was finished,lapsus palpebrae superioris and shorted transverse diameter of coloboma of eye lid had been rectified satisfactorily.All cases we followed up for three monthes to one year,and dislocation of lacrmial gland had been amended in one case,others had been reposited well,without recurrence.Conclusions Blepharochalasis can be effectively treated by surgery,and it is convenient and effective to treat dislocation of lacrimal gland and blepharochalasis through a double eyelid fold incision.This multiple surgical treatment is not only a curative operation but also a cosmetic surgery.

Objective To analyze the relationship between HA orbital implantation and its complications.Methods and Results The authors retrospectively reviewed 38 cases,among which 24cases received unwrapped HA implantation,5 of them became exposure(20.8%);14 wrapped in autologous sclera,only 1 became exposure(7.1%),there was significant difference between the two types of surgery(P

Objective To study the genetic polymorphism of Nanjiang yellow goat and to investigate the feasibility of this research by AFLP. Methods The genomic DNAs of 15 goats were analyzed with RAPD and AFLP molecule marking techniques. The effects of the two methods were compared. Results The rates of the polymorphic loci and the genetic similar index of population by RAPD marker were 26.98% and 0.942 respectively, and that by 31.4% AFLP and 0.874 respectively. Conclusion AFLP and RAPD technique are effective methods in genetic polymorphism monitoring of Nanjiang yellow goats, and supply useful parameter with appraise genetic stability.
