OBJECTIVE:To summarize the key issues such as the drug waste and the phone calls affecting the working efficiency in pharmacy intravenous admixture service(PIVAS)and to put forward countermeasures so as to improve the working quality there.METHODS:The records about the drug waste in PIVAS and the phone calls that affected the working efficiency from clinical departments were analyzed statistically.RESULTS:Dispensing error and drug return were the main factors accountable for the drug waste in PIVAS.The proportion of phone calls from clinical departments demanding drug bills and drug dispensing was the highest,which greatly affected the working efficiency in PIVAS.CONCLUSIONS:The clinical staff should be informed not to make the unnecessary calls to PIVAS so as to improve the working quality in PIVAS.

OBJECTIVE: To analyze the drug return in our hospital and to put forward countermeasures.METHODS: The drug return in our hospital from 2004 to 2006 was analyzed retrospectively in respect of the amount of money,drug variety and causes.RESULTS: The amount of money of returned drugs increased rapidly in 2005 than the previous year,but decreased in 2006.The major varieties were injectable drugs,followed by anti-infective drugs.Doctors' modification of medical orders was the main reason accountable for drug return.CONCLUSION: It is suggested that effective measures be taken in hospital to strengthen publicizing and management on the rational drug use,standardize procedure of drug return,and improve hospital computer system etc.

Objective To investigate the effect of dexamethasone on the expression of APQ-4 and cytokines in the hematoma and brain tissue of ICH rats. Methods The treatment group was treated with injection of 1mg/kg and dexamethasone, and the model group and the sham operation group were injected with the same amount of normal saline. Results The model group APQ-4, TNF- positive cells. The proportion of second, third, the highest in the 7d after the operation, the sham operation group was the lowest (P<0.05). Conclusion Dexamethasone is beneficial to reduce the APQ-4 expression in brain tissue of rats in ICH, while reducing the expression of TNF- alpha.

Objective To evaluate the acute side effects and efficacy of three dimensional conformal radiotherapy (3D-CRT) combined with gemcitabine chemotherapy for locally advanced non-small cell lung cancer (NSCLC). Methods From January 2006 to December 2007, 90 cases with advanced NSCLC were divided into two groups, treatment group of 45 patients were tre.ated with 3D-CRT and gemcitabine, control group of 45 patients were treated with gemcitabine and conventional radiotherapy. Chemotherapy consisted of intravenously gemeitabine 350 mg/m2 on day 1, 8, 15, 22, 29, 36. Radioactive source was used with X ray of 6 MV or 15 MV. Irradiatial target area were lung site and mediastinal node. Results The complete remission (CR)and remission rate(RR) in centrol group were 5 cases (11.1%) and 28 cases(62.2%), but in treatment group were 13 cases (28.9%) and 38 cases (84.4%), respectively. The difference of response rate in two groups was significant(P < 0.05). The rate of acute radiation-induced pneumonifis and esophagitis in control group (28.9%, 35.6%)were higher than those in treatment group (11.1%, 17.8%), there were significant difference between two groups (P < 0.05). Conclusions Concurrent application of gemcitabine and 3D-CRT can improve the RR for locally advanced NSCLC, and the acute toxicity are lower than those of gemcitabine and conventional radiotherapy. The clinical study is needed, but the late effect shoud be followed.

AIM: To investigate the effect of monoclonal antibody(McAb) AU_(14-1) mediated cytotoxicity against cervical cancer U_(14) cell in vitro.METHODS: MTT colorimetric assay was applied to study the McAb AU_(14-1) mediated cytotoxicity of effector cells including splenocytes,peritoneal macrophages and LAK to U_(14) cells.RESULTS: The cytotoxicity mediated by each effector cells to the U_(14) cells treated with McAb AU_(14-1) was significantly higher than those not treated with it(P

Objective To investigate the clinical value of susceptibility weighted imaging (SWI)combined with three dimensional pseudo continuous arterial spin labeling (3D-PCASL)on the prognosis analysis of acute cerebral infarction.Methods Thirty cases with acute cerebral infarction (< 72 h)underwent conventional MRI,MRA,3D-PCASL and SWI.NIHSS scores were performed at the time of examination and 3 months later.The correlation between the collateral blood vessels,regional cerebral blood flow (rCBF)detected by combination of SWI and 3D-PCASL with clinical prognosis were analyzed.Results Twenty-three cases showed collateral blood vessels in the lesions with 1 grade in 14,and 2 grade in 9.The average rCBFs in grade 0,1,2 infarction areas were (22.69±11.94)mL·100 g-1 ·min-1 ,(25.10±16.55)mL·100 g-1 ·min-1 and (33.04±24.24)mL·100 g-1 ·min-1 ,respectively.Collateral blood vessels,rCBF were positive correlated with the NIHSS scores (r=0.989,P< 0.01).18 cases showed multiple vessels around the lesions. The average rCBFs in the infarction area with or not with periphery collateral blood vessles were (28.33±24.24)mL·100 g-1 ·min-1 and (22.69±11.94)mL·100 g-1 ·min-1 ,respectively.There was a positive correlation between rCBF and NIHSS scores (r=0.897,P<0.01). Of 30 cases of acute cerebral infarction,the average CBFs in the infarct areas and the contralateral mirror areas were (26.92±18.22)mL·100 g-1 · min-1 and (34.22±12.37)mL·100 g-1 ·min-1 .There was significant difference (t=8.093,P<0.01).Conclusion The combination of SWI and 3D-PCASL can display the collateral blood vessels in the lesions and soft meninges,and provide the quantitative analysis of rCBF,which has important clinical significance for prediction of the prognosis of acute cerebral infarction.

Objective: To evaluate the post-operative complication of pulmonary vein stenosis in patients with total anomalous pulmonary venous connection (TAPVC) by echocardiography.
Methods: A total of 66 TAPVC pediatric patients with surgical repair in our hospital were retrospectively studied. The peri-operative and mid-term post-operative echocardiography was conducted to evaluate the complication of pulmonary vein stenosis.
Results: The peri-operative and mid-term post-operative echocardiography presented the increased left ventricular diastolic end diameter (LVEDd) and decreased right ventricular diameter in all 66 patients, P<0.05. There were 6 patients with pulmonary vein stenosis showed high velocity Doppler signals at atanastomosis. The peri-operative echocardiography in those 6 patients showed increased LVEDd, decreased right ventricular diameter and pulmonary artery pressure, all P<0.05. The mid-term post-operative echocardiography in those 6 patients indicated increased LVEDd, P<0.05, while the right ventricular diameter and pulmonary artery pressure were similar before and after the operation, P>0.05.
Conclusion: Echocardiography may monitor the operative effect of TAPVC, the occurrence of post-operative pulmonary vein stenosis could be found by examining right ventricular diameter and pulmonary artery pressure in pediatric patients.

onary artery was turtuous and dilated in 4 cases. Conclusion 64 MSCT is emerging as an essential imaging tool for detecting early anomalous origin of the left coronary artery from the pulmonary artery with high resolution and significance.

Objective To evaluate the role of echocardiography in diagnosis and post-operative evaluation of infants and children with double aortic arch. Methods Echocardiography was performed in 6 patients with double aortic arch from January 2006 to June 2008. The outcome of postoperative follow-up was also evaluated. Results Six patients ranged in age from 3 months to 4 years and averaged 18 months. There were 2 boys and 4 girls. Echocardiography diagnosed double aortic arch in 4 patients, one balanced arch and 3 right arch dominant, and was confirmed by surgical observation in each patient. The size of the two arches were almost same in balanced arch,and the diameter of right arch was bigger than that of left arch in right arch dominant. Echocardiography failed to diagnose in 2 patients with balanced arch. Three patients had associated heart defect, such as patent ductus arteriosus and ventricular septal defect. Five of the 6 patients underwent surgical division of the left arch in order to relieve esophageal and tracheal compression. At about 2 years postoperative follow-up,echocardiography can clearly show the flow of aortic arch and it's branches. Conclusions It is an important clue to double aortic arch if only two branches of aortic arch was shown on supersternal view by echocardiography. As a non-invasive techniqe, echocardiography is useful for diagnosing and post-operative evaluating of patients with double aortic arch.
