Obiective To analyze the characteristics of antibacterial drugs caused adverse drug reactions (ADR) and correlation with DDDs in Ezhou Central Hospital,and provide reference for safe and rational use of antibacterial drug in clinic.Methods ADR reports of antibacterial drugs in Ezhou Central Hospital from September 2011 to August 2016 were entered into Microsoft Excel 2000 software,Statistical analysis was performed on the categories of antimicrobials,drug names,clinical manifestations,and DDDs,composition ratio of ADR and ratio ofB/A.Results Involved in 151 ADR cases and 10 kinds of antibacterial drugs,the top 3 antibacterial drugs respectively were Fluoroquinolones,Cephalosporins,and Penicillins,the top 3 DDDs respectively were Cephalosporins,Fluoroquinolones,and Macrolides,and the B/A values of Cephalosporins,Macrolides,and Antifungal agents were over 1.The top 4 ADR composition ratios respectively were Levofloxacin,Moxifloxacin,Cefmetazole,and Cefotiam,and the top 4 DDDs respectively were Levofloxacin,Cefodizime sodium,Azithromycin,and Cefmetazole,and the B/A ratios of Cefodizime sodium,Metronidazole,and Azithromycin were over than 1.Levofloxacin and moxifloxacin had a higher risk of severe ADR,and Levofloxacin and Cefotiadine had a higher risk of new ADR.Conclusion The ADR rate of antibacterial drugs is basic consistent with its DDDs.Clinical should pay more attention to the individual drugs with higher rates of ADR,such as Cefodizime sodium,metronidazole,and azithromycin etc.

Objective To study the effect of thalidomide and arsenic trioxide on the proliferation and apoptosis effect in human myelodysplastic syndrome cell line MUTZ-1 and explore its possible mechanism.Methods MUTZ-1 cells were cultured with different concentration of thalidomide alone, arsenic trioxide alone, and thalidomide plus arsenic trioxide for 48 h. The cell proliferation was analyzed by CCK-8 test, and cell apoptosis was analyzed by flow cytometry. The expression of Bmi-1 was analyzed by semi-quantitative RT-PCR. Results Thalidomide alone had no significant inhibition on growth of MUTZ-1 cells (P >0.05).Arsenic trioxide alone had obviously inhibited the cell proliferation (P <0.05). While thalidomide plus arsenic trioxide group had the great inhibition effect(CDI <0.7), and reveal was that two drugs had synergism effect on inhibiting the MUTZ-1 cells. Arsenic trioxide group of apoptosis rate was increased with higher concentrations of drug, a dose-dependent (r = 0.627, P <0.05), thalidomide in the rate of apoptosis with no increase in drug concentration significantly (r= 0.313, P> 0.05), and the combined group with the drug also increased the concentration of expression (P <0.05). In arsenic trioxide group the expression of Bmi-1 / β-actin declined with the increased concentration, a dose-dependent (r =-0.912, P<0.05), thalidomide group Bmi-1 / β-actin with the increased concentration of no significant decline (r =-0.594, P >0.05), the combined group Bmi-1 inhibition was significantly higher than arsenic trioxide, thalidomide in a separate drug group (CDI <0.7).Conclusion Thalidomide group had no significant growth inhibition. Arsenic trioxide on MUTZ-1 cells significantly inhibited the growth and increased in the combined group significantly.

Objective To evaluate the efficacy and side effects of standard-dose of dexamethasone and low-dose dexamethasone combined with thalidomide in treatment of multiple myeloma. Methods Thirtynine patients with multiple myeloma were randomly divided into 2 groups, who were treated with chemotherapy of thalidomide (200 mg/d) plus dexamethasone (40 mg d1-46728 days in standard-dose group and 20 mg dl-4d/28 days in low-dose group), for a total of 4 courses. The efficacy, survival time and adverse events were compared between the two groups. Results Complete remission rate, partial remission rate and overall response rate of the standard-dose group were 26.3 %, 35 % and 75 %, respectively; and those of the low-dose group were 15.8% , 36.8 % and 68.4 %, respectively. No statistical difference between the two groups (P >0.05 ) was observed. Lung infections, blood pressure elevation, blood glucose elevation, shingles and other adverse reactions in the standard-dose group were statistically higher than those in the low-dose group (P <0.05). Conclusion Efficacy on multiple myeloma of standard-dose and low-dose dexamethasone are similar, but adverse reactions are significantly increased.

Objective To assess the efficacy and tolerability of continuous low-dose cyclophosphamide and prednisone regimen(CP)as salvage therapy for multiple myeloma patients with severe complications.Methods The CP regimen consisted of oral cyclophosphamide at 50 mg and oral prednisone at 15 mg daily.The patients were withdrawn if the response was invalid or not improved after 6 months,and follow-up was carried on if CR maintained for 6 weeks.A total of 23 consecutive patients received the CP regimen,with 18 patients having severe complications,and 5 patients unwilling to accept conventional chemotherapy because of severe infection.All patients had received one to four regimens before.Results Among 23 patients with CP regimen,the overall response rate(CR+VGPR+PR)was 61%,with 1 CR,4 VGPR,9 PR,3 MR and 6 PD.The quality of life and physical conditions were improved significandy.Conclusion Our data showed that CP was an effective,well-tolerated,and convenient regimen as salvage therapy for MM with severe complications.

A total of 160 type 2 diabetic patients were divided into microalbuminuria(42 cases)and normoalbuminuria(118 cases)groups.Multivariate analysis demonstrated that the presence of microalbuminuria was independently associated with brachial-ankle pulse wave velocity(baPWV)and intima-media thickness(both P

Objective To discuss the outcome of repair of limbs bone defect by using mineralized collagen graft.Methods The clinical data of 35 cases who diagnosed the existence of bone defect from January 2013 to December 2013 in our department were retrospectively analyzed.After operation,Lane Sandhu X-ray score standard was evaluated.Results All patients were followed up for 12 months.Postoperative 1 month,Lane Sandhu X-ray score was 3 points in 20 cases and 15 cases with 2 pointss;postoperative 6 months,Lane Sandhu X-ray score was 9 points in 21 cases,10 cases with 8 points and 4 cases with 7 points.Postoperative 12 months,Lane Sandhu X-ray score was 12 points in 28 cases,7 cases with 11 points.The scores of postoperative 6 months were better than the scores of postoperative 1 month [(2.60±0.49)points vs.(8.49±0.12)points,t=107.860,P=0.000].There was significant difference between the scores of postoperative 12 months and scores of postoperative 6 months [(8.49±0.12)points vs.(11.8±0.06)points,t=41.630,P=0.000].Conclusion MC is used as an effective bone substitute material,and its clinical effect is good.

Purpose Estimation of the degree of pulmonary artery stenosis (PS) in children patients before treatment can provide an important basis for the choice of treatment.This study explores the accuracy of non-invasive continuous wave Doppler (CW) and electrocardiogram (ECG) in estimating the degree of PS in children patients.Materials and Methods Sixty consecutive cases of PS children were collected from January 2012 to August 2016 in the General Hospital of Shenyang Military.The right ventricular pressure was estimated by measuring cross-pulmonary artery pressure gradient by CW,or estimated by measuring the amplitude of the V1R wave by ECG,which was then compared with that measured by cardiac catheterization respectively.Results The right ventricular pressure estimated by measuring cross-pulmonary artery pressure gradient by CW was positively correlated with that measured by cardiac catheterization (r=0.88,P＜0.05).The right ventricular pressure estimated by measuring the amplitude of the V1R wave by ECG was also positively correlated with that measured by cardiac catheterization (r=0.83,P＜0.05).Conclusion The right ventricular pressure estimated by CW or ECG has good consistency with that measured by cardiac catheterization.Both CW and ECG can be used as noninvasive methods for estimating the degree of PS in children.
