OBJECTIVE:To optimize the management of drug inventory so as to reduce days of drug turnover. METHODS:Depending on the information management system of the hospital,the method of quality control circle was used to analyze the rea-sons of long days of drug turnover,corresponding measures for continuous improvement were developed,and the effects of the ac-tivities in the quality control circle were evaluated on the basis of the rate of achieving the goal and the growth rate of circle mem-bers. RESULTS:In the activities of the quality control circle,based on the factors such as personnel,drugs and the method,corre-sponding measures were developed in respect of permanent applicants for drugs,the upper and lower limits of drugs to be gotten by the applicant,the increase in the frequency of purchase,“zero inventory”management for part of drugs,and the optimization of the generation program of purchase orders,where the percentage of the drugs with the turnover days within 15 d was increased from 72% to over 85%,the rate of achieving the goal was 107.9%. All the circle members significantly grew as to the application of the method of quality control circle,sense of responsibility,initiative,team spirit,communication and coordination,with growth rate of 12%-28%. CONCLUSIONS:The activities of the quality control circle have achieved a good effect in optimizing the drug inventory management of our hospital and increased the percentage of the drugs with the turnover days within 15 d.

With the strengthening of nuclear weapon development and the expanding of neutron application in economic area,the injury accidents of neutron radiation are happening from time to time.Neutron exposure,with high linear energy transfer,has high casualty rate,severe symptom and poor prognosis.In comparison with low-LET radiation damage,neutron irradiation induced injuries are more difficult to rescue.This review focused on the recent research progresses of radiation effects,intrinsic mechanisms and clinical prevention measures of neutron radiation,and to provide a theoretical clue for establishing an effective prevention protocol of neutron radiation damage.

Objective To evaluate effect of intervention on acquired immune deficiency syndrome(AIDS) high-risk sexual behavior of males who have sex with males(MSM)population in Jilin,and to provide a basis for establishing apropriate intervention strategy for this population.Methods A cross-sectional survey was carried out on the MSM population of young students with the method of classification.Comprehensive intervention strategy included health education via new media,behavioral intervention,voluntary conseling and testing,peer education,condom promotion and standardized services for clinic of sexually transmitted diseases(STDs)and other comprehensive interventions.Before and after intervention,300 MSM were enrolled,and their demographic characteristics,knowledge of AIDS prevention and control,high risk behaviors and intervention measures were investigated and analyzed.Results Before and after the intervention,the awareness rate of AIDS related knowledge was 67.67% and 94.33%,respectively,the condom usage rate was 23.57% and 11.79% in the most recent and the last 6 months before the intervention,and it was 76.21% and 62.10 % after the intervention,respectively.The proportion for those who used condom every time in heterosexual sex behavior was increased from 23.53% (before intervention) to 69.60 % (after intervention),and the condom usage rate in the last 6 months was increased from 15.44% to 66.40%.Proportion of the MSM who had STDs related symptoms was decreased from 21.33% to 7.67% after the intervention.Conclusion After the comprehensive intervention,the awareness rate of AIDS related knowledge among MSM in Jilin is significantly increased,the incidence of highrisk sexual behavior is decreased and the condom usage rate is improved.Intervention by use of new media is low-cost,easy to operate,and can be used as a good supplementary strategy for traditional behavioral intervention.

Objective To investigate the effectiveness of surgical resection for metastatic liver cancer in patients of gastric carcinoma, and evaluate the prognosis. Methods Clinical data of 24 gastric cancer cases undergoing hepatectomy for hepatic metastatic tumor were collected retrospectively. There were 18 cases of synchronous resection and 6 cases of heterochronous resection. The prognostic values of clinicopathological factors were assessed by univariate and multivariate analyses. Results Postoperatively all cases were followed up until the death of the patietns. Counting from the time of liver resection the 1-,3- and 5-year survival rate was 67%, 21% and 13% respectively. Univariate analysis showed lymph node involved, tumor size of hepatic metastases, vascular invasion and R0 margin as significant prognostic factors;Multivariate analysis indicated that tumor size of hepatic metastases and vascular invasion were independent prognostic factors influencing the survival. Conclusion These results suggest that for patients with liver metastasia from gastric cancer, better prognosis can be obtained by surgical treatment.

The clinical data of 147 patients with carcinoma of ampulla of Vatar at our hospital from January 1998 to December 2012 were retrospectively analyzed.The neutrophil-to-lymphocyte ratio ( NLR) was calculated from pre-operative complete blood count.They were divided into low NLR group (NLR<5,n=121) and high NLR group (NLR≥5,n=26).The 5-year survival rates of two groups were compared and the prognostic risk factors examined by univariate analysis and Cox model.The 5-year free survival rates of low and high NLR groups were 57.9%and 27.6%respectively ( P=0.005 ).Univariate analysis revealed that depth of invasion (P=0.006),pancreatic invasion (P=0.002),lymph nodal metastasis (P=0.008), poor differentiation ( P =0.008 ) , tumor stage ( P =0.003 ) and per-operative NLR ( P =0.005 ) were significant prognostic factors.Multivariate analysis showed that per-operative NLR significantly increased the risk of recurrence (P<0.05).Pre-operative NLR represents a significant independent prognostic indicator for patients with carcinoma of ampulla of Vatar.

Objective To study the clinical feature,diagnosis,treatment and prognosis of hepatocellular adenoma(HA).Methods The clinical data of 10 patients confirmed pathologically with HA,were retrospectively analyzed.Results There were four females and six males,aging from 25 to 71 years(mean:42.6 years).Among these 10 patients,6 cases were discovered to have no clinical symptom.Tumors were located in the right lobe of the liver in 4 cases,and in the left lobe in 6 cases.Uhrasonography was performed in all cases.Six cases underwent CT examination and three cases experienced MRI as well as angiography was conducted in one case.All cases were confirmed by complete excision and pathology.All of them were followed up for 5 months to 9 years without tumor recurrence.Conclusion The combination of imaging data is helpful in the diagnosis of HA.Surgery is the best treatment with satisfactory results,and its prognosis is fairly good.

Objective To study the diagnosis and treatment of pancreatic cystadenoma and cystadenocarcinoma.Methods The clinical data of 21 surgically treated patients of the cystic neoplasms of pancreas(CNP),confirmed by pathology,in recent 8 years were retrospectively analyzed.Results CNP was more frequently seen in young to middle-aged women.Upper abdominal mass and abdominal distention and pain were the main clinical presentations.The CNP resection rate was 95%(100%and 80%in benign and malignant CNP respectively).Of the 21cases,pancreaticoduodenectomy and distal pancreatectomy were performed in 2 and 16 respectively;and middle segment pancreatectomy in 2 patients.Postoperative pancreatic fistula was the leading complication.Conclusion CNP have no clinical characteristics.Ultrasonography and CT could be helpful to the diagnosis of CNP.The resection of the whole tumor with part paratumor pancreas tissue is advocated.
