Objective To observe the results of 45 cases with acquired immunodeficiency syndrome(AIDS) genotypic viral resistance test(GT) assay.Method The technitues provided by AB Applied Biosystem was used to check the mutations in the reverse transcriptase associated with significant viral resistance.Results Fourteen cases out of 40(35%)cases which failed from first line regimen showed resistance to both zedovudine(ZDV) and lamivudine(LMV),and 26 cases out of 40(65%) cases showed resistance to ZDV or lamivudine used in the first line.For no-nucleoside reverse transcriptase in habitor(NNRTIs),11 cases out of 40(27%) cases had resistance to nevirapine(NVP),29 cases out of 40(63%) cases showed resistance to both NVP and efairavir(EFV).Two cases out of 5 which failed from second line regimen showed that one drug from both first and second line had no resistance,so it still could be used in the new regimen.Conclusion GT assay is very useful for choosing a best and personalized regimen for AIDS patients.

This article introduces the way of making and using ultrasound multimedia courseware,which can improve teaching means,enrich teaching contents,activate classroom atmosphere and enhance the connection of basic and clinical knowledge.Meanwhile,the environment request of the demonstration courseware and interaction courseware as well as the necessity and significance of multimedia in ultrasound teaching are discussed.It is suggested that computer assisted instruction(CAI) plays an important role in ultrasound teaching.

Objective To study effect of drug treatment in polycystic ovary syndrome patients with hyperprolactinemia.Methods We retrospectively studied 50 women with polycystic ovary syndrome and hyperprolactinemia from the outpatient between January 2005 and April 2008.Acccording to the beginning time of bmmocriptine.all women were divided into two groups.Groups Ⅰ was composed of 38 cases who received bromocriptine before induction of ovulation cycies,and the dose of bromocriptine was modulated depending on the level of serum prolaotin.When serum prolactin was controlled at normal levels,we decreased the dosage of bromocriptine step by step(1.25mg once),and then continued the treatment at maintenance dosage for no less than 3 weeks.After a baseline ultrasonographic examination on day 3,patients were treated with clomiphene citrate at a dosage of 100mg(2 tablets/day)for 5 days of a normal cycle or progesterone-induced bleeding.On day 9.we monitored the growth conditions of follicles routinely with trails-vagihal ultrasound.If there was no dominant follicle,we added human menopausal hormone(HMG 75U/d)to the protocol.Human chorionic gonadotropin(HCG,5 000-10 000IU)was given intramuscularly when the mean diameter of a follicle reached at least 18mm.At the same time we iustmcted the patients to have sexual intercourses or carried out artificial inseminations before and after ovulation.Group Ⅱ were 12 cases in which induction of ovulations were commenced almost simultaneously with beginning of bromeoriptine.The same protucol was given to patients in group Ⅱ.The procedures of ovulation induction and the outcomes of treatment were analyzed and compared.Results Compared with groupⅡ.the days of using HMG in group Ⅰ was shorter by instructing the time of sexual intercourse.The difference was significant(P=0.004).And there were similar rosults in the artificial insemination cycles(P=0.009).The rate of pregnancy in group Ⅰ(42% 16/38)was higher than that in group Ⅱ(25%,3/12),but the difference was not obvious.Conclusion Bromocriptine administration before the stimulated ovulation therapy can decrease the total dosage and treatment course of ovulating drugs.Induction of ovulations simultaneously with start of bromocriptine therapy can shorten the treatment time of infertility.

Objective To evaluate the efficacy of zoledronic acid combined with radiotherapy for metastatic bone tumours. Methods Eighty patients with metastatic bone tumour by meta were randomly derided into two groups study group(n=40), and the eantrol group (n=40). The study group received 4 mg zoledronic acid infusion for 15 minutes combined with radiotherapy (DT 30Gy/10f/2w) ,control group was only treated with radiotherapy. The primary effective parameters were pain scores, quality of life, KPS scores and pain relief rates. The vital signs, bi-ochemical and hematological parameters were determined. Results The overall response rates of study group and control group were 97.5% and 72.5% ,respectively(P<0.05). The overall response rate of movement capacity im-provement was 87.5 % in the study group and 65.0% in the control group(P<0.05). There was statistical signifi-cance of QOL and KPS in two groups (P<0.01). An adverse event of mild systemic skeletal pain was recorded after pamidronate infusion and completely reversed after 8 hours. Conclusion Zoledronic acid combined with radiothera-py is effective and safe for treating malignant tumour with mestastatic bone tumours. It is a better way to treat meta-static bone tumors at present.

The cost-benefit analysis of medical equipment investment has been paid much more attention by the hospitals' decision makers. The overall planning should been strengthened before the introduction of equipments and doing a good job in market research contributes to exert equipments' effectiveness. The equipment use and management being strengthened can significantly reduce the costs and improve the efficiency and effectiveness,and furthermore,end-of-life equipment management are also important factors to reduce costs. The investigation is based on the same one among Grade II hospitals in Shanghai in 2007. Referring to the result of similar investigation in 2005,analysis and thinking from different aspects are showed to offer some reference in the future device assets management of hospitals.

Through the Introduction of the visualization technology based on VREL and its application in ultrasound teaching,the teaching means has been changed,the teaching content enriched and the contact between basic and clinic knowledge enhanced,which indicates that the visualization technology exerts an important role in ultrasound teaching.

time of infusion. Data analysis indicated that A1B3C2 was the best combination of the 3 factors according to the degree of lung injury. Conclusion Adequate amount of HES 200/0.5 infused during compensated stage of hypovolemic shock produces best result.

Objective To investigate the character 、difference and clinical meaning of distortion product otoacoustic emissions(DPOAE) and auditory brainstem respons(ABR) in high risk neonates with.Methods DPOAE and ABR were recorded with amplaid MK 22 and GSI60 in 200(400ears) high risk neonates, then compared the results.Results Of 200(400ears) newborns, the presence of DPOAE was 64%(256/400 ears), the presence of ABR was 88.25%(353/400 ears). The co-negativity and co-positivity of DPOAE and ABR were 61.50%(246/400 ears)and 9.25%(37/400 ears). The false negative and false positive of DPOAE were 3.91%(10/256 ears)and 74.31%(107/144 ears).Conclusion The DPOAE test is simple,quick,harmless,sensitive and objective. Because it only reflects the function of the cochlea and has high false positive, we can't make the diagnosis of hearing loss immediately when newborns don't pass the DPOAE test.The ABR test is a reliable method for neonatal hearing screening. The combination of DPOAE and ABR in high risk neonatal hearing screening could increase the accuracy and reliability of the test and retest results.

Objective:To investigate the medical equipment quality control work which need to be improved in Shanghai medical institutions, and evaluate the acceptability of hospital management team on regional medical equipment quality control checks and standard, so as to seek the corresponding solutions.Methods: The 92 copies of self-designed medical equipment management standard questionnaire was distributed, 76 valid questionnaires were reveived, the received rate of 83%.Results: Only 70% of the people thought the major difficulty is the shortage of medical equipment management staff; 97% thought the quality control has great impact on improvement of medical equipment management. Quality control center determined the annual topics about the problems and needs to form the problem oriented, team based, expert resource collaborative working model. And studied and formulated three specifications and recommendations templates. We carried out a four-month intensive training and received critical acclaim.Conclusion: Medical equipment management staff proposed new requirements. Questionnaire objectively reflected the difficulties in the quality control inspection work, but also pointed out the direction for the future management of the quality of promotion. It provided the thought to improve the quality management and to enhance management methods and training models in the future.
