OBJECTIVE:To evolve the method for effective clinical pharmacy practice. METHODS:The contents and outcome of the clinical pharmacy practice in our hospital was evaluated. RESULTS & CONCLUSION:The practice of clinical pharmacy work can help guide and promote clinical rational drug use.

Objective To understand the trend of occurrence,diagnosis,and prognosis of breast cancer in the cases treated in Peking Union Medical College Hospital(PUMCH) between 1975 and 2006.Methods A total of 1092 cases of breast cancer treated in the PUMCH from 1975 to 2006 were classified into six groups by time span and reviewed for a comparative study on the parameters of gender,age,menstruation status,tumor size,mumber of positive axillary nodes,pathologic stage,recurrence and metastasis and disease-free survival rate.Results The average age of breast cancer patient has risen from 50.90 to 53.92,while 40-49 year-old group was the largest age group of breast cancer patients,and the percentage of menopause female was the highest.Tumor size has gradually been smaller especially since 2000.The number of positive axillary nodes showed no significant change during the time periods.In all 6 groups,stage-II cases were more frequent,although the percentage of stage-0 and stage-I cases was on the rise,while the percentage of stage-III declined,and that of stage-IV remained stable.In all 6 groups,the 5-year and 10-year disease free survival rate had steadily increased.Conclusions The early diagnostic rate of breast cancer has been improving and subsequently the prognosis has improved as well.

Objective To investigate the accuracy of contrast enhanced ultrasound (CEUS) in diagnosing acute severe panereatitis.Methods Thirty three patients with acute severe pancreatitis were enrolled in the study and all of them underwent CEUS and spiral computed tomography(CT) scan.CT was taken as gold standard in acute severe pancreatitis diagnosis.CEUS were done within 72 hours after CT scan.Results Compared with CT, the sensitivity, specificity,accuracy, positive predictive value,and negative predictive value of CEUS for detecting the necrosis of pancreas were 90%, 95%, 94%, 90% and 95%respectively.The sensitivity, specificity, accuracy, positive predictive value,and negative predictive value of CEUS in diagnosing severe acute pancreatitis were 85%, 92%, 88%, 94% and 80% respectively, while 37% ,86% ,58%, 78%, 50% for conventional ultrasound respectively.Conclusions CEUS is accurate in detection of pancreatic necrosis and diagnosis of acute severe pancreatitis.

Objective To construct short-hairpin RNA (shRNA) eukaryotic express vectors targeting of insulin like growth factor-1 receptor (IGF1R) gene, and to explore the changes of adhesion, invasion and FAK protein expression of MHCC-97 H hepatocellular carcinoma cells with RNA interference. Methods The shRNA oligonucleotide fragments were designed and synthesized based on the sequence of IGF1R mRNA. Double strands were formed after annealing and inserted into pGCsi-U6-Neo-GFP vector. The recombinant was transformed into Stable 3, then plasmids were extracted and identified by restriction enzyme and sequencing analysis. The most effective vectors were selected by RT-PCR and Western blotting after transfecting 293T cells. The best one was used to transform MHCC-97H cells which were selected with G418 to obtain positive colons. The changes of adhesion, invasion and FAK protein expression in MHCC-97H cells were studied. Results The restriction enzyme analysis and sequencing analysis demonstrated that shRNA had been inserted into vectors, and their sequences were the same as the design. It was indicated by RT-PCR and Western blotting that the silencing efficacy of IGF1R was 88%. The ability of adhesion and invasion significantly decreased after IGF1R silencing in MHCC-97H cells, and so was the expression of FAK protein. Conclusion IGF1R pGCsi-U6-Neo-GFP shRNA can significantly decrease the abilities of adhesion and invasion in MHCC-97H cells, and inhibit the expression of FAK protein.

Objective To study the relationship of expression of central cortex glucocorticoid receptor (GR) at protein level with GR expression in the liver at protein level and with changes of serum cortisol and adrenocorticotropic hormone (ACTH) following severe closed traumatic brain injury (TBI) in mice. Methods Severe TBI was established in awake mice by using a BIM-Ⅲ biomechanical machine. At 0.5, 2, 8, 24, 48 and 72 hours after TBI, the total cytosolic GR in the cortex and liver were detected with Western blotting. Levels of serum ACTH and cortisol were measured by ELISA technique and radio-immunological assay (RIA) respectively. Results The expression of GR both in the cortex and liver were obviously down-regulated at protein levels at 2-72 hours after TBI and increased slowly eight hours after injury. The GR in the liver showed no recovery at 72 hours after injury and that in the cortex was decreased continually at 24 hours after injury. Serum ACTH and cortisol levels were increased markedly compared with control group, when there were two different peaks in the observation curve.Conclusion There is glucocorticoid resistance both in the central and peripheral tissues after severe closed TBI in the awake mice, which changes in a time-dependent manner.

Objective To develop the Chinese version of the 35-item Medical Outcomes Study HIV Health Survey (MOS-HIV) and to assess the reliability and validity of MOS-HIV among HIV-infected individuals.Methods Between April and July of 2007,a croas-sectional survey of 758 HIV-infected individuals was conducted.Responses to the MOS- HIV were analyzed for its reliability and validity.Results Pearson's correlation coefficients of items for test-retest relia- bility ranged from 0.46-0.92,all internal consistency reliability coefficients exceeded 0.69,and all items were more strongly correlated with hypothesized scale than any other scale.Eight scales of MOS-HIV were significantly associated with CD_4 cell counts.Conclusions The Chinese version of MOS-HIV offers good reliability and validity and can be used as a tool to assess the quality of life of HIV infected individuals in China,thus providing evidence for further studying AIDS related quality of life in this country.
