Objective To investigate the characteristics of human immunodeficiency virus(HIV-1)V3 loop amino acid mutations among AIDS patients in Shenzhen. Methods Fragments of HIV-1 env gene were amplified by RT-nested-polymerase chain reaction(PCR)from plasma of the AIDS patients in Shenzhen.The PCR products were then directly sequenced and the sequences were aligned,translated and analyzed. Results Sequence analysis showed that there were B and CRF01-AE HIV-1 subtypes in Shenzhen.The V3 loop terra peptide GPGQ accounted for about 48%,GPGR about 36%,other V3 loop terra peptide forms were 16%;the V3 loop central motif in the majority(76.9%)of the CRF01-AE strains was GPGQ,the majority(75%)of the B strains was GPGR.We also found some unusual terra peptide compositions:DQDR and DQGQ on the tip of V3 loop,some amino acid mutations at specific of V3 loop associated with SI phenotype were very common in AIDS patients(80%). Conclusions The V3 loop amino acid mutations were very common in AIDS patients,the V3 loop central motif in the majority was GPGQ and GPGR in Shenzhen,the mutations shows the change of HIV-1 phenotype and predicts that disease progress to AIDS.

Objective To investigate the MRI features and the diagnostic value of uterine leiomyoma.Methods All cases were examinated by MRI and ultrasound.Retrospective analysis of MRI manifestations of 71 uterine leiomyomas in 32 patients in combination with the results of operation and pathology was carried out and was compared with ultrasound findings.Results The MRI features of the tumors were:intermediate or slightly low signal intensity on T 1WI and low signal intensity on T 2WI,patch hyperintense areas were seen in degenerated leiomyoma on T 2WI,there were clear margins in all tumors and capsules in most tumors(55/71).MRI was superior to sonography in showing 

ObjectiveTo evaluate the performance of diagnosis-related groups,Beijing version (BJ-DRGs) which were locally developed in Beijing.MethodA total of 1.3 million inpatient records from 149 hospitals in Beijing in 2008 were drawn from Beijing Public Information Center.Coefficient of variation (CV) was used to measure the performance of DRGs system.ResultsBJ-DRGs produced the best CV results for expenditure.ConclusionsUnder Beijing's medical information condition,BJ-DRGs produced good performance.

Diagnosis related groups (DRGs)have been widely used in many countries and regions.The versions of DRGs in different regions are modified according to the local circumstances and conditions.Beijing version DRGs (BJ-DRGs)is the first DRGs system in Chinese,which was developed locally based on the conditions of medical information system and health relative policies in Beijing.This paper introduced the grouping principles,logic and methodology of BJ-DRGs.Taking“ear,nose,mouth and throat disorders”for example,this paper demonstrated the grouping process of BJ-DRGs.

OBJECTIVE:To establish evaluation system and quality management of dispensing department in hospital and provide basis for comprehensive and correct assessment of pharmacy dispensing work.METHODS:Based on the platform of human resource management,the flow and job responsibility of drug dispensing were adjusted."Drug dispensing work quality management specification and performance evaluation system" was established and put into practice.RESULTS:Drug dispensing quality management had criteria and principles to go by.The level of management staff were improved dramatically.58.3% of department administrators were younger than 40 years old,who were recruited and went on duty after passing examination.CONCLUSION:"Drug dispensing work quality management specification and performance evaluation system" is the comprehensive requirement of effectively ensuring the quality of drug dispending work and safety of drug utilization and reflects the standard and scientific management of drug dispensing.

OBJECTIVE:To discusses the influencing factors on the safety and efficacy of pediatric drugs.METHODS:The errors in administration of pediatric drugs were analyzed.The drugs under current use in the pediatric pharmacy of our hospital were classified and compared as per quantity,dosage form,specification,medication safety, direction and medicine evaluation. RESULTS: The influencing factors mainly included the subjective factors(wrong drug treatment) and the objective factors (pharmaceutical factors and social factors) .CONCLUSION: To safeguard the efficacy and safety of pediatric drugs, it' s advisable that an evaluation or control system for rational use of pediatric drugs be established with the participation of the society, the hospital and patients.

Objective Beijing plans to run a DRGs-PPS pilot.The relative height of each DRG group produced by the price of charge categories.Because of serious distortions of medical services prices,DRGs'weight must be adjusted.Methods Dividing medical service into 5 major class-medical,nursing,technique,drugs and consumables,management,a conversion with currency were established to produce the cost.Results The weight of groups involve intervention from MDCF are drop.ConclusionThe weight regulated can optimize resources allocation and reflect the ture value of medical service.

Objective The aim of this study was to assess the relationship between the oral health habit and halitosis. It can provide an advisory basis for nurse giving individualized oral health instruction to patients of halitosis and can improve the result of prevention and treatment for halitosis accordingly. Methods 202 patients with periodontal disease were chosen to participate in this study. The study included the questionnaire of oral health habit and the halitosis diagnosis by organoleptic assessment.Comparisons of difference in the knowledge of oral health habit between the subjects with and without halitosis were conducted. Results Brushing times in subjects without halitosis were significantly more than that in subjects with halitosis. Brushing teeth in evening and interproximal brush usage were much better in subjects without halitosis than that in subjects with halitosis,respectively. Conclusions Good oral health habits could decrease the incidence of halitosis.

Objective To study the expression of fascin, an actin bundling protein associated with cell motility, and the relationship with ER negative breast carcinoma.Methods Comparasion of the expression of fascin, estrogen receptor (ER) and proliferative cell nuclear antigen (PCNA) determined by immunohistological method was made on 84 specimens of primary breast carcinomas. Results The diffuse staining of fascin in cancerous cell cytoplasm was noted. Only 3 of 53 breast carcinomas with ER positive showed fascin positive expression (5.67%); in contrast, 21 of 31 carcinomas with ER-negative showed positive expression(67.7 %) (P
