OBJECTIVE:To provide reference for promoting the rational use of national essential medicines in antibiotics. METHODS:The use of national essential drugs in antibiotics in 3 second-level general hospitals from Chongming area of Shanghai from 2011 to 2013 were statistically analyzed. RESULTS:The sales amount of antibiotics was in an increasing trend,with an aver-age growth rate of 28.16%;while the proportion of sales amount accounted for the total sales amount of drugs were still relatively low,with an average growth rate of 2.16%. The proportion of total sales amount of top 3 antibiotics from 2011 to 2013 accounted for the total sales amount of drugs were respectively 87.92%,93.60% and 95.54%,with an increasing trend;while compared with 2011,the DDDs of national essential medicines in antibiotics was decreased a little during 2012-2013;the top 2 DDDs were Cefuroxime axetil tablets and Amoxicillin capsules,the top 1 sales amount was Cefuroxime sodium for injection. Varieties with the sales amount/ DDDs close to 1 were relatively less,indicating that the sales amount of drugs and the number of drug use was not synchronous. CONCLUSIONS:There are still some problems in the utilization of national essential medicines in antibiotics. It needs to be continuously improved in the related work to further improve medication rationality and economy,and progressively re-alize the institutionalized and normalized antibiotics in clinical use management.

Objective To summarize the treatment experience of the solitary kidney with renal artery aneurysm.Methods Clinical data of 1 solitary renal artery aneurysm patient treated in our hospital in May.2012 was retrospectively analyzed.The 48 yrs man with a history of hypertension for 10 years,but responded to medical treatment poorly.The highest blood pressure was up to 180/100 mmHg (1 mmHg =0.133 kPa).Preoperative check found that the serum creatinine was 64 μmol/L.Color Doppler ultrasound showed no detection of left kidney,the renal artery enlarged to the range of 21 mm× 14 mm.CT scan showed that the right renal artery locally enlarged,suggesting artery aneurysm.Renal computerized tomography angiography showed that left renal agenesis,right renal with artery aneurysm close to the renal hilum with size of 17.1 mm× 19.1 mm,was located on the distal renal artery bifurcation,involving 2 artery branches.The diagnosis was right solitary kidney with renal artery aneurysm.Renal aneurysm clip occlusion was performed under general anesthesia,blood pressure was controlled to 70/40 mmHg during the procedure.After exposing the renal artery,the renal artery was visible with a diameter of 25 mm and with a basement width about 19 mm,which located in the main renal artery and overrode the branches of the two renal arteries.After the clamp of the artery aneurysm from two sides to center and the middle part of it was overlapped,the artery aneurysm reduced obviously,and clipped the aneurysmal wall with noose suture.When loosen the clamp of main renal artery,the artery aneurysm was not enlarged,blood pressure up to 120/80 mmHg.Results The operation was successful,operation time was 75 min,intraoperative blocking time was 15 min,intraoperative blood loss was 50 ml,and there was no intraoperative and postoperative complication.Postoperatively immediate and the first postoperative day serum creatinine were 95 μmol/L and 150 μmol/L.2 week after surgery the index decreased to 74 μmol/L.After operation the blood pressure was control successful,and kept at 130/80 mmHg.Conclusions Solitary kidney with renal artery aneurysm is rare.Renal aneurysm clip occlusion is a safe,effective and feasible treatment option,especially for the patients with solitary kidney.

OBJECTIVE:To compare the efficacy and safety of desloratadine citrate disodium and acrivastine decremental thera-py in the treatment of chronic urticaria. METHODS:132 patients with chronic urticaria were randomly divided into group A(62 cases)and group B(70 cases). Group A was orally given 8.8 mg Desloratadine citrate disodium tablet in 12 2 weeks,once a day;8.8 mg in 3-4 weeks,once every 2 days;8.8 mg in 5-6 weeks,once every 3 days;8.8 mg in 7-8 weeks,once every 4 days;and 8.8 mg in 9-10 weeks,once every 5 days. Group B was orally given 8 mg Acrivastine capsule in 12 2 weeks,3 times a day;8 mg in 3-4 weeks,twice a day;8 mg in 5-6 weeks,once a day;8 mg in 7-8 weeks,once every 2 days;and 8 mg in 9-10 weeks, once every 3 days. The treatment course for both groups was 10 weeks. Clinical efficacy,and plasma histamine levels and total scores of signs and symptoms before and after treatment in 2 groups were observed,and recurrence and incidence of adverse reac-tions after 4 weeks of stopping drugs in 2 groups were followed-up. RESULTS:There were no significant difference in the total ef-fective rate and incidence of adverse reactions between 2 groups(P>0.05). After treatment,the total scores of signs and symptoms in 2 groups were significantly lower than before,the difference was statistically significant(P<0.01),and there was no significant difference between 2 groups(P>0.05). The recurrence rate in group A was significantly lower than group B,the difference was sta-tistically significant(P<0.05). CONCLUSIONS:Both efficacy and safety of desloratadine citrate disodium and acrivastine decre-mental therapy in the treatment of chronic urticaria are good,however,desloratadine citrate disodium is better than acrivastine in re-ducing recurrence rate.
