Chinese Journal of Primary Medicine and Pharmacy 2017;24(15):2317-2320
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 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.

Objective To explore the significance and methods of surgical treatment of mammary hyperplasia. Methods Patients with mammary hyperplasia were treated by different operative procedures,and cosmetic operations were performed synchronously on some selected patients. Results 523 cases were treated by surgery. All cases were diagnosed as mammary hyperplasia on the pathological examination and were in good condition postoperatively. The results of synchronous cosmetic operation were satisfactory . Conclusions The surgical treatment of mammary hyperplasia should be done if the efficacy was not satisfatory after the therapy combined traditional chinese medicine with western medicine . The operative indications must be defined carefully.

Objective To study the liver damage induced by platelet activating factor (PAF) and the protective effects of the PAF antagonist WEB2170. Methods Experiments in vivo: after the administration of PAF to induce liver damage in rats, serum levels of aspartate transaminase (AST), alanine transaminase (ALT), lactic dehydrogenase (LDH) and tissue malonyldialdehyde (MDA) were determined by biochemical method, the succinate dehydrogenase (SDH) activity in mitochondrion was assessed by histochemical method, and the morphologic changes in hepatic structure were observed. In the treatment group, WEB2170 was used for intervention. Experiments in vitro: the fluidity of cellular velum of liver cells was detected with DPH probe, and the effect of TNF and MDA produced by Kupffer cells cultured by PAF stimulation was observed. Results PAF increased the expression of serum AST, ALT, LDH and tissue MDA (P
