OBJECTIVE:To investigate the effect of clinical pharmacist intervention on prophylactic application of antibiotics in cardiothoracic surgery. METHODS:Medical records of patients underwent cardiothoracic surgery were collected from our hospi-tal during Mar. to Apr. in 2014 (before intervention) and during Jun. to Jul. in 2014 (after intervention). Those were divided into pre-intervention group(n=115)and post-intervention group(n=119). The prophylactic application effect of antibiotics was com-pared before and after intervention. RESULTS:After intervention,the rates of prophylactic application were decreased significantly from 96.5% to 72.3%;the rationality rate of antibiotics selection was improved significantly from 27.9% to 94.2%;The course of prophylactic medication decreased significantly from(5.4±2.8)days to(2.3±1.8)days;the difference had statistical significance before and after intervention(P<0.01). The postoperative infection rate was decreased from 13.0% to 5.9%,the difference had no statistical significance(P=0.074). The average hospitalization time,average drug costs,and average hospitalization expenses were decreased significantly,the difference had statistical significance(P<0.05 or P<0.01). CONCLUSIONS:Clinical pharmacist inter-vention to prophylactic application of antibiotics in cardiothoracic surgery can control the infection effective and guarantee reason-able and safe use of drugs during perioperative period.

Epiretinal membrane (ERM) is a relatively common macular disease that forms along the surface of the internal limiting membrane (ILM) of the retina to some reason.The pathogenesis is not clear.Microincision vitrectomy surgery has been confirmed as a minimally invasive and very safe modality of treatment.Deciding when to perform a vitrectomy can be difficult.There are many factors which can affect the postoperative visual acuity,such as age,the thickness of macular,integrity of photoreceptor inner segment/outer segment (IS/OS) junction.

Objective To analyse the clinical effect of Quantianma capsules combined with flupentixol and melitracen tablets on chronic migraine. Methods 130 patients with chronic migraine were treated with flupentixol and melitracen tablets, were divided into control group and observation group, 65 patients in each group. The observation group were given to Quantianma capsules. Results The effective rate of observation group with 90.77% was higher than control group with 73.85%(P<0.05). After treatment, the number of migraine attacks, duration time, VAS score, HAMA and HAMD score and mean flow velocity of cerebral artery of two groups were lower than pre-treatment and observation group were lower than that of control group(P<0.05). Adverse reactions were similar in the two groups. Conclusion Quantianma capsules can improve the efficacy of treatment of chronic migraine combined with flupentixol and melitracen tablets and improve condition with few adverse effects.

Objective:To evaluate the effect of continuing intervention on prophylactic application of antibiotics in sterile operation in urology department by clinical pharmacist to provide reference for the clinical prophylactic application of antibiotics. Methods:All cases of discharged patients underwent sterile operation in urology department of our hospital from July 2010 to June 2014 were divided into three groups according to the intervention time and methods: non-intervention group(n=141), stage Ⅰ intervention group(n=139), stage Ⅱ intervention group (n=162) and stage Ⅲ intervention group (n=137). The prophylactic application of antibiotics was statistically analyzed. Results:After the continuing intervention, the prophylactic application rate of antibiotics in the three inter-vention groups was decreased significantly from 100% before the intervention respectively to 34. 5%,18. 5% and 14. 6% after the in-tervention (P<0. 01). The rationality rate of prophylactic application was improved significantly from 36. 9% before the intervention respectively to 58. 3%, 63. 3% and 85. 0% after the intervention (P<0. 01). The course of prophylactic application was decreased significantly from (138.2 ±31.6)h respectively to (89.9 ±48.0)h,(72.8 ±32.5)h and(45.1 ±29.5)h (P<0.01) and the post-operative infection rate was decreased from 2. 8% respectively to 2. 1%,1. 8% and 1. 4%. Conclusion:The pharmaceutical interven-tion is feasible and valid to improve the rational prophylactic use of antibiotics in urological surgery.

SUMMARY Our work focused on the studies on the expression and function of transient receptor poten -tial vanilloid subtype 1 ( TRPV1) in the submandibular gland .By using reverse transcription-polymerase chain reaction ( RT-PCR ) , Western blotting , and immunofluorescence , our data demonstrated the expression and distribution characteristics of TRPV 1 in rabbit and human submandibular glands , as well as rat submandibular gland cell line SMG-C6.Furthermore, the possible intracellular signal molecules involved in the TRPV1-modulated saliva secretion were explored .Activation of TRPV1 increased the intracellular Ca2+concentration, upregulated the expression of aquaporin 5 (AQP5), the main transpor-ter that mediate water secretion through transcellular pathway , and led to AQP5 redistribution .Extracel-lular signal-regulated kinase 1/2 ( ERK1/2 ) was involved in the TRPV1-regulated AQP5 content. Besides, TRPV1 activation also modulated the expression , distribution, and function of tight junction protein, and increased paracellular permeability .ERK1/2 and myosin light chain 2 ( MLC2 ) were responsible for the regulation of TRPV1on tight junction properties.Taken together, our work suggested that TRPV1 was a potential target to promote saliva secretion , and activation of TRPV1 might provide a new and safe therapeutic strategy to ameliorate submandibular gland hypofunction .

Objective:To investigate the possibility of predicting facial nerve involvement in the pa-tients with parotid tumors using facial electroneurography (ENoG).Methods:In the study, 53 patients with primary parotid tumors were included in the study , 28 were benign tumors and 25 were malignant . There was no significant difference of tumor locations and sizes between the two groups . House-Brackmann facial nerve function evaluation was gradeⅠin all the patients who received examination of fa-cial electroneurography , including stimulation strength , amplitude , and latent time bilaterally .The facial electroneurography results in the affected side were compared with the results of contralateral normal side , intraoperative appearance and postoperative histopathological diagnosis .The facial electroneurography results were analyzed by Wilcoxon signed rank test and receiver operator characteristic ( ROC) curve. Results:During the facial electroneurography examination , the mean stimulation strength in the patients with benign parotid tumor was 20.0 mA.There was significant decrease in the amplitude at the affected side compared with the normal side upon posterior auricular stimulation ( P<0 .05 ) .But there was no significant difference in the latent time between the bilateral sides (P>0.05).However, in the patients with malignant parotid tumor , the mean stimulation strength was higher at 24.5 mA.There was signifi-cant decrease in the amplitude or even no response at the affected side compared to the normal side upon posterior auricular stimulation ( P<0 .05 ) .No response was detected in the multiple branches of facial nerve of affected sides in 36 .0%patients upon posterior auricular stimulation .The amplitude of branchesⅢand Ⅳwas significantly lower at the affected side than that at the normal side upon anterior auricular stimulation (P<0.05).The area under the ROC curve for ENoG was 0.884.Conclusion: When the facial nerve was involved by the parotid tumors , the stimulation strength in the electroneurography was larger .There was significant difference in the amplitude and the latent time of the facial nerve between the affected side and the normal side upon the posterior auricular stimulation .The rate of absence of reac-tion wave was higher in the patients with malignant tumors .It was feasible to predict the facial nerve in-volvement by ENoG for the parotid gland tumor patients without clinical appearances of facial paralysis .
