Objective To analyze the application of antimicrobial agents before and after the improvement of prescription evaluation system in Green Town Cardiovascular Hospital.Methods One thousand outpatient prescriptions of antimicrobial agents were randomly selected from our hospital from January 2014 to January 2016,serving as the data before intervention.These prescriptions were analyzed according to the prescription evaluation system and effective interventions were proposed according to the existing problems in prescriptions.Another 1 000 effective prescriptions of antimicrobial agents during February 2015 to January 2016 in our hospital were taken as the data after intervention.Unreasonable use of antimicrobial agents and the satisfaction degree of physicians,nurses and patients towards the prescription were compared before and after intervention.Results After intervention,the percentage of unreasonable use of antimicrobial agents from May 2015 to May 2016 (2.10%) was significantly lower than that from April 2014 to April 2015 (30.00%),the difference was statistically significant (χ2=288.857,P<0.05).The satisfaction degree of physicians,nurses and patients towards the prescription from May 2015 to May 2016 [(93.23±5.93)points,(95.29±6.01)points,(68.99±4.27)points] was significantly higher than that from April 2014 to April 2015 [(75.34±5.32)points,(71.46±5.13)points,(68.99±4.27)points],the difference was statistically significant (t=110.706,95.368,123.711,all P<0.05).Conclusion The improvement of prescription evaluation system can obviously improve unreasonable use of antimicrobial agents,increase the satisfaction degree,avoid drug abuse,produce obvious effect and great significance.

Objective:To examine the soft tissue changes of early skeletal Class III malocclusion patients after maxillary protraction treatment. Methods:60 skeletal anterior crossbite patients, 27 males, 33 females in the late mixed dentition were selected. The age ranged from 8 to 11 years. Mean age was 9.3 years. The patients were divided into treatment group and control group. Average treatment time was 12.1 months. Pre- and post-treatment lateral cephalograms of both groups were traced and analyzed. Difference between pre- and post-treatment was analyzed with paired t-tests. Results:After treatment, Ns-Sn-Pos, Ns-Prn-Pos, Sn-S-Si and Cm-Sn-UL decreased significantly,while Sn-Ns-Si and UL-E increased significantly. No significant change was found in S-Ns-Sn and LL-E. Conclusion:Soft tissue profiles are significantly improved by maxillary protraction treatment in the late mixed dentition. The concave profiles were changed to straight or nearly normal profiles. The relationship among nose, upper lip, lower lip and chin become harmonious. The curve of the lips tends to be smooth and harmonious.

Objective To analyze the β-lactamases-producing Escherichia coli which were isolated from hospital specimens from Jun 2012 to Dec 2014,and provide a more accurate evidence to guide drug-selecting for antibacterial use.Methods An-alyzed 1 587 E.coli from patient sample selected between Jun 2012~Dec 2014 using the microbial analysis system manufac-tured by ZHUHAI DL BIOTECH CO.LTD,A phenotypic test was also conducted to test ESBLs.Results 1 587 stains of E-.coli were isolated,which counted for 23.9% of the specimens;901 stains (56.8%)out of total 1 587 stains appeared to be ESBLs-producing E.coli,and others were non-ESBLs-producing E.coli.The 1 587 Escherichia coli mainly came from De-partment of Urology (408,weight 25.7%),Department of Endocrinology (271,weight 17.1%),Department of Respiration (249,weight 15.7%).Rine specimen contributed 609 stains (47.3%),411 E.coli stains (31.9%)were discovered in spu-tum samples,and 83 stains (6.5%)showed in blood samples.The resistance to imipenem were discovered in the analysis. The rates of resistance to penicillins,cephalosporins were over 90.0%,the rates of resistance to Levofloxacin,ciprofloxacin were above 70.0%,and resistance rates to amoxicillin-clavulanic acid,Ticarcillin-clavulanic acid,piperacillin/tazobactam, amikacin were lower than 7.7%.Conclusion The drug-resistance of the E.coli were increasing over the past three years. There was a significant portion of MDR and PDR present in the trend.Thus,the reinforcement of the drug-resistance survey and testing have a far-reaching meaning to promote rational drug selecting.

Objective:To observe the effect of Chinese herbal fumigation combined with three-step tuina manipulation on concentration of endothelin (ET) and calcitonin gene-related peptide (CGRP) and vertigo in patients with vertebral artery cervical spondylosis (VACS).
Methods:A total of 120 eligible cases were randomly allocated into an observation group and a control group, 60 in each group. Cases in the observation group were treated with Chinese herbal fumigation combined with three-step tuina manipulation, whereas cases in the control group were treated with oral Flunarizine Hydrochloride Capsules.
Results: After treatment, vertigo in both groups was alleviated; there were intra-group significant differences in ET decrease and CGRP increase (P<0.01, P<0.05);and there were also inter-group significant differences (both P<0.05).
Conclusion: Chinese herbal fumigation combined with three-step tuina manipulation can regulate the levels of ET and CGRP and improve vertigo in patients with VACS. Its therapeutic efficacy is superior to oral Flunarizine Hydrochloride Capsules.

Objective To study the adsorption ability of the chitosan and the chitosan film to Cd2+. Methods Under the given condition,different time and different temperature and different beginning concentration of Cd2+, the adsorption rate and capability of the chitosan and the chitosan film were studied. Results The chitosan (or chitosan film) could adsorb Cd2+ quickly at first,however,an hour later,the adsorption rate declined slowly. Adsorption rate increased as the temperature increases. There was significant connection between the beginning concentration of Cd2+ and the adsorption rate and capability of the chitosan(or chitosan film). The adsorption rate of the chitosan (or chitosan film) even reached above 80% when the beginning concentration of Cd2+ was no more than 20 mg/L, whereas the adsorption rate and capability of the chitosan (or chitosan film) declined slowly when enhanced the beginning concentration of Cd2+. The adsorption rate and capability of the chitosan (or chitosan film) obtained a maximum only when the beginning concentration of Cd2+ was about 10 mg/L. The adsorptive ability of the chitosan film to Cd2+ was stronger than that of chitosan under the same condition. Conclusion The biosorption of the chitosan (or chitosan film) to Cd2+ fits the Langmuir equation and the adsorbability to Cd2+ of the chitosan film is stronger compared with chitosanb.
