OBJECTIVE:To provide reference for promoting rational use of vancomycin in the clinic. METHODS:Referring to vancomycin instruction,Guiding Principles for Clinical Use of Antibacterials (2015 edition) and Chinese Expert Consensus on Clinical Use of Vancomycin (2011 edition),720 inpatient medical records of vancomycin were collected from our hospital during Jan. 2013-Dec. 2014,and then drug use of those inpatients were analyzed retrospectively. RESULTS:Among 720 cases,male (428 cases)was more than female(292 cases),and most of them aged 41-65(45.83%). There were 50 cases of prophylactic drug use(6.94%)and 670 cases of therapeutic drug use(93.06%). The patients came from 36 departments. Among 720 cases,the dose of 19 cases were higher than 2 g/d,and there were 13 ADR cases(1.81%). Among 670 cases of therapeutic drug use,587 cases of microbiological samples (87.61%) were detected,and other antibacterials were used in 522 cases additionally (77.91%). DUI of vancomycin was equal to 0.96 in 549 cases no younger than 18 years old of herapeutic drug use. There were 240 cases of unsuit-able drug use (33.33%) in total,including 192 cases of unsuitable solvent (26.67%),28 cases of unsuitable usage and dosage (3.89%)and 20 cases of unsuitable drug combination(2.78%). CONCLUSIONS:The use of vancomycin in our hospital is basi-cally rational;vancomycin is widely used in departments;drug combination is a common phenomenon;the inspection rate of mi-crobiological samples is qualified;no drug abuse is found. However,there still is inappropriate use in the clinic. It is recommended to strengthen special evaluation and training about rational use of vancomycin,and further standardize monitoring for vancomycin use so as to guarantee the safety of drug use.

Objective To evaluate the outcomes of penoplasty with penile frenulum lengthening for concealed penis in children.Methods From March 2014 to March 2016,a total of 233 patients with concealed penis who enderwent penoplasty with penile frenulum lengthening were enrolled.The everage age at surgery was 3.7 years (1 year and seven months-12 years).There were 73 cases with obvious small urinary stream,dysuria,or prepuce dilatation when urinating;41 cases with the history of recurrent infections of prepuces;and 9 cases with the history of urinary tract infections.During operation,incise the back side center of the outer plate of the prepuce and fully release the ring-type funicular tissue between the inner and outer plates of the prepuce to make the inner plate fully swell out.After the prepuce is upturned,cut the penile frenulum at the coronary sulcus.Make a V-shaped cut on the left and right sides of the far end of the outer plate cut of the prepuce from the cut of the penile frenulum.Lengthen penile frenulum after the prepuce is pressed off.Cover the dorsal side of the penis with the inner plate of the prepuce and cover its ventral side with its outer plate.Results Mean surgical time for patients was 38 min (30-55 min).All operations were completed successfully and the post-operation follow-up lasts 3 months to 2 years.For all cases,the appearance of the penis is improved.The penis stretches out,the balanus is exposed,the prepuce has no obvious swelling and the scrotum angle of the penis is obvious.No phimosis relapses and there is no obvious scar hyperplasia.Conclusions This surgical procedure is an effective treatment choice for concealed penis.It provides a good cosmetic result.

Objective To evaluate the effect of the clinical nursing path integrated with the holistic nursing on advanced schistosomiasis patients with ascites. Methods A total of 226 advanced schistosomiasis patients with ascites were randomly di?vided into a control group and an experimental group (113 cases each group). The subjects in the experimental group were nursed by the clinical nursing path integrated with the holistic nursing,while those in the control group were nursed only by the holistic nursing. Then the clinical relevant indexes of the two groups were observed,and the quality of life of the patients before and after hospital discharge was assessed. Results The improvement rate,satisfaction degree,and awareness rate of health knowledge of the patients in the experiment group were 93.8%,100%and 97.4%,respectively,which were significantly higher than those of the control group(all P<0.05). The mortality rate and the complication rate of the patients in the experimental group were 0 and 2.7%,respectively,which were significantly lower than those of the control group(both P<0.05). In addi?tion,the average hospitalization days and the hospitalization cost of the experiment group were(12.2 ± 0.7)d and(4 725.0 ± 310.1)Yuan respectively,which were less than those of the control group(both P<0.01). When 6 months after the discharge from hospital,the quality of life of the patients in the experimental group in various fields was significantly better than that of the control group(all P<0.05). Conclusions The clinical nursing pathway integrated with holistic nursing can effectively improve the improvement rate and decrease the mortality of the advanced schistosomiasis patients with ascites;meanwhile,it can short?en the hospitalization time and save the hospitalization cost. Therefore,this nursing model is suitable for popularization and ap?plication in the treatment and nursing work of the advanced schistosomiasis assistance.
