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 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.

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.

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

BACKGROUND:In the process of designing knee joint prosthesis and operating total knee arthroplasty for the Chinese people, we should not only take into account the proximal tibial anatomical characteristics and the difference of geometry, but also should pay attention to the differences between different races. OBJECTIVE:To compare the anatomical morphological differences between Mongolian and Han nationality through measuring the CT tomography scanning and three-dimensional reconstruction measurement of tibia proximal part of Han and Mongolian nationality, so as to provide the data references for prosthesis selection used for total knee arthroplasty. METHODS:Total y 60 patients who received the treatment at the Department of Joint Surgery were col ected, and divided into Han nationality and Mongolian nationality groups (n=30/group, 15 males and 15 females in each group). The age was (36.00+7.22) years old. 16-row helical CT scan (American GE Lightspeed 16) was used for spiral scanning, slice thickness 0.625 mm. Scanning images were exported in DICOM format and saved. Digital three-dimensional reconstruction measurement was conducted using Mimics 15.0 three-dimensional reconstruction software. The tibial plateau width, anteroposterior diameter of the medial tibial plateau and lateral anteroposterior diameter were measured respectively to observe whether there were any differences among sex, sides and nationality. RESULTS AND CONCLUSION:There were no significant differences in the above indicators between left and right sides (P>0.05). There were significant differences in tibial plateau width, anteroposterior diameter of the medial tibial plateau and lateral anteroposterior diameter between males and females, and Han and Mongolian nationality groups (P<0.05). Specific performed in:(1) There was significant difference in the morphological measurement parameters of proximal tibia between sex for Han and Mongolian nationality, and the mean value of male was larger compared with that of female. (2) There was certain significant difference in the part of the parameter indicators between Han and Mongolian nationality groups. These results suggest that the prosthesis should be chose and placed correctly according to the differences of morphological characteristics, gender, nationality, region of the Chinese people. (3) Digital three-dimensional reconstruction technology and individualized design can choose suitable prosthesis for different people, so as to ensure a good repair effect in patients after total knee replacement.

Purpurin is a common component ofRubia cordifolia L. The study on its molecular target was useful for elucidating the therapeutic material basis and action mechanism ofR. cordifolia. HT-29 cells were used in the cell culture. The highly expressed G Protein-coupled Receptor-35 (GPR35) agonist was used as target. The label-free optical biosensor cellular assay was used to investigate the agonist activity ofpurpurin at an endogenous receptor. The results showed thatpurpurin can cause DMR response in HT-29 cells. And the DMR response curve type was consistent with zaprinast. Its EC50 was 6.142± 0.189μmol·L-1. In addition,purpurinhad desensitization effect on GPR35 agonist zaprinast in HT-29 cells. GPR35 agonist ML145 blocked the DMR ofpurpurin. It was concluded thatpurpurinwas the GPR35 agonist.
