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 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.

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.

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.
