METHODS: The causes of dispensing error in computerized community pharmacy and the related countermeasures were discussed. RESULTS: To prevent dispnesing error in the computerized community pharmacy, it is urgernt for the concerned personnel to improve their professional level and working ability and arrange drugs scientifically. CONCLUSION: Great importance should be attached to the dispensing error in community pharmacy to provide patients with a high quality community health service.

Objective To investigate the efficacy of laparoscopy for the treatment of rectovaginal septum endometriosis. Methods A totalof 13 patients with rectovaginal septum endometriosis underwent open (5 cases) or laparoscopic (8 cases) operations in our hospital between January 2001 and May 2006.Results In the open surgery group,the operation time ranged from 130 to 200 minutes (mean,187 minutes) ,and the mean intraoperative blood loss was 189 ml (170 to 280).After the operation,the menstrual pain was relieved in 5 cases at 1 month,4 at 3 months,3 at 6 months,and 2 at 12 months.Whereas,in the laparoscopy group,the operation time ranged from 120 to 185 minutes (mean,155 minutes),and the mean blood loss was 135 ml(100 to 190 ml).The menstrual pain was relieved in 8 cases at month 1,8 cases at month 3,7 cases at month 6,and 5 cases at month 12.Conclusions Laparoscopic surgery is effective and safe for patients with rectovaginal septum endometriosis.

Objective To explore the role of platelet activating factor(PAF) and its receptor in portal hypertension in liver cirrhosis. Methods A model of hepatic cirrhosis was replicated in rat by intraperitoneal injection of CCL 4 for 8 weeks. The blood and hepatic PAF and PAF receptors contents were assayed with ELISA, RT-PCR and saturation binding technique. Results Compared with control rats, cirrhotic rats had higher hepatic PAF levels, hepatic PAF output, and plasma PAF levels, which were increased by 44%, 87.7% and 54.5%(P

Objective To analyze the clinical and pathological features and responses to therapy of primary biliary cirrhosis(PBC) and autoimmune hepatitis(AIH) overlap syndrome. Methods Comparison was made between 11 patients with PBC/AIH overlap syndrome, 21 cases with type I AIH and 20 cases with PBC (Scheuer stage Ⅰ and Ⅱ), and the emphases was laid upon the clinical manifestations, pathological features and responses to therapy of the patients with PBC/AIH overlap syndrome. Results No significant differences were found in sex, age and course of diseases among the three groups. In PBC/AIH group, the serum levels of alkaline phosphatase (AKP), ?-glutamyl-transpeptidase (GTP), IgM and the frequency of positive anti-mitochondrial antibodies (AMA) and AMA-M2 antibodies were significantly higher than those in the pure AIH group(P

Objective To study the changes in PAF and its receptor in Kupffer cells in experimental cirrhosis and to evaluate the role of activated Kupffer cells in portal hypertension. Methods Kupffer cells, isolated from the livers of control and CCl_4-induced cirrhotic rats, were cultured in serum-free medium overnight. PAF synthesis and release by Kupffer cells were determined 24 h later by rapid ~3H-PAF scintillation proximity assay, and the expression of PAF receptor in Kupffer cells by saturation binding technique and semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR). By immunohistochemisty, the distribution of PAF in Kupffer cells was surveyed. Results Cell-associated PAF synthesis and release was increased about 1.48 fold and 2 fold, respectively, by Kupffer cells in cirrhotic liver as compared with the control (P0.05). Consistent with the receptor binding capacity, the mRNA expression of PAF receptor increased significantly in the Kupffer cells of cirrhotic liver (P

Objective To observe the influence of Zhenweifang on the muscle tension in flaccid paralysis period and prognosis of stroke.Methods One hundred and eighty patients were randomly divided into basic group,Buyanghuanwutang group and Zhenweifang group.Basic group was treated with usual medical treatment with nerve rehabitilation and acupuncture.Buyanghuanwutang group and Zhenweifang group were given the corresponding traditional Chinese medicine.Patients in Buyanghuanwutang group and Zhenweifang group stop taking the traditional Chinese medicine when their muscle tension reach the level of Ashworth Grade Ⅱ,and continued their basic treatment.The defect of neurological and daily life ability were evaluated after three-week and six-week treatment,and the prognosis was evaluated according to clinical efficacy.Results The time that patients muscle tension in Zhenweifang group need to reach Ashworth Grade Ⅱ was much shorter than that in Buyanghuanwutang group and basic group(P

s Objective To study the effect of HBV DNA of pregnant mothers on HBV intrauterine transmission. Methods Thirty one pairs of mothers and their newborn babies were detected for HBV by the HBV DNA qualitative PCR and HBV serology, as well as the concentration of HBV DNA in the blood by fluorescence quantitative PCR. Results There was a positive linear regression( r=0.5401, P=0.0017 ) between the concentration of HBV DNA in the infant and that in the mothers. Among the 31 infants, 19 showed abnormal by HBV DNA qualitative PCR and(or) HBV serology. It indicated that there was vertical transmission from the mothers to their infants. The transmission rate is 61%. The concentration of HBV DNA copies/ml(7.2?3.1) in mothers whose infants were abnormal was significantly higher than the others(5.8?1.3). Among the 31 mothers, 6 cases showed anti-HB positive and their babies were of much lower concentration of HBV DNA(4.2?1.8) than others(6.1?1.8). Conclusion The quantity of HBV in mothers reflected the strength of HBV vertical transmission and the chance of HBV transmission from mothers to infants have been decreased after mothers have obtained HbsAb.

[Objective]To explore the surgical feasibility and clinical outcome of pedicle screw instrument for treatment of irreducible atlantoaxial dislocation and to choose an effective method of internal fixation.[Method]From June 2003 to February 2009,14 pationts with atlas dislocation followed by upper cervical cord compression were treated surgically with oral anterior soft tissue release combined with posterior reduction and pedicle screw instrument.Preoperative CT,MRI and radiographs as well as intraoperative screw placement and bone graft were administered in all pationts.Only cervical collars were used as external support for 3 months in occipitocervical fusion.[Result]All screws were successfully placed in atlas and axis.Forteen patients were followed up for an average of 18 months.Bone fusion was achieved in all cases with no complications of nerve,internal fixation failure and redislocation.Neurological recovery was significantly improved in 12 cases and took a turn for better in 2 cases.[Conclusion]Pedicle screw instrument in atlas and axis has the advantages of direct screw placement,short-segment fusion,intraoperative reduction and high fusion rate.It is a better alternative for atlantoaxial dislocation.

[ ABSTRACT] AIM:To investigate the effect of DEC1 gene over-expression on the proliferation and invasion abili-ties of human esophageal cancer ECA109 cells.METHODS: ECA109 cells were transfected with plasmid pcDNA3.1 (-)/DEC1 (DEC1 group) or pcDNA3.1 (-) (vector group).The mRNA and protein levels of DEC1, cyclin D1 and MMP-9 were evaluated by real-time PCR and Western blot, respectively.The effects of DEC1 over-expression on the prolif-eration and invasion abilities of the ECA109 cells were evaluated by CCK-8 assay, colony formation assay and Transwell test respectively.RESULTS:The DEC1 expression level in ECA109 cells in DEC1 group was significantly higher than that in vector group (P<0.01), but the levels of MMP9 and cyclin D1 expression were opposite (P<0.01).However, both the proliferation and invasion abilities of ECA109 cells in DEC1 groups decreased significantly as compared with those in vector group (P<0.05).CONCLUSION:The over-expression of DEC1 significantly inhibits the proliferation and invasion of ECA109 cells, which may be involved in the expression of cyclin D1 and MMP9.
