OBJECTIVE:To provide reference for the promotion of rational use of essential medicines and further implementa-tion of essential medicines system. METHODS:Depended on the data (including the number of species,the amount of prescrip-tion and prescription departments,etc)of essential medicines(chemical drugs and biological drugs)use in outpatient and emergen-cy departments and wards of 20 sample medical and health institutions fromThe Hospital Prescriptions Cooperation Project,statis-tical analysis was performed by using Excel and Access software. RESULTS:The proportion of the amount of essential medicines included in National Essential Medicines List(2012 edition)or Beijing Essential Medicines(Supplementary list)(2012 edition)to the amount of total medicines(hereinafter referred to as the essential medicines use ratio)in medical and health institutions of Bei-jing from 2013 to the first half year of 2014 was small and showed a slight downward trend. The essential medicines use ratio of grade 2 and grade 3 general hospitals did not reached the required ratio by former Health Department. The essential medicines use ratio in different departments showed great differences,the essential medicines use ratio in imaging department was 100%,while chemotherapy departnent was 4.04%. The essential medicines use ratio in different medicines also showed great differences,5 kinds of drugs(including sulfani lamides)was 100%,while there were 16 kinds of drugs that was less than 0.1%. CONCLUSIONS:The essential medicines use ratio is relatively low in medical and health institutions of Beijing from 2013 to the first half year of 2014 and shows great differences in different departments and different medicines. It is suggested to further improve the essential medi-cines use ratio to better benefit the majority of patients by changing the prescribing habits of physicians,strengthening the advocacy of essential medicines policy and optimizing the use of essential medicines in different departments.

OBJECTIVE:Analyze drug use of pediatrics in China,and to provide reference for promoting research,develop-ment and supply of pediatric drugs. METHODS:Analyze the data of drug use in 2 632 514 pediatric patients aged from 0 to 14 of 78 sample hospitals from Beijing,Shanghai,Tianjin,Hangzhou,Zhengzhou,Guangzhou and Chengdu in“The Hospital Prescriptions Cooperation Project”of Hospital Pharmacy Professional Committee of Chinese Pharmaceutical Association,statistical analysis was performed by using Excel and Access software. RESULTS:Pediatric patients in 78 sample hospitals of 7 regions had used 1 572 kinds of drugs from 2013 to 2014,but only 31.04%of drugs were pediatric drugs;both the ratio of pediatric drug types and the ra-tio of pediatric drugs use frequency had a great gap in different drug classifications. The ratio of drug use frequency in injection ad-ministration was 57.97%,and it was greatly higher than that of oral administration(31.04%). Among oral solid preparations,the ratio of drug use frequency for drugs with unreasonable specification was 29.57%,and ratio of drug types was 40.99%. CONCLU-SIONS:The pediatric patients had a great drug shortage in kinds,dosage forms and specifications in 78 sample hospitals of 7 re-gions during 2013-2014. Off-label drug use,high frequence of injection use,tablets used after breaking and other irrational phenom-ena were found in pediatric patients during clinical drug therapy,which reduced high risk of drug use. It is recommended that gov-ernment should strengthen and improve incentives mechanism of research,development and supply of pediatric drugs,so as to solve pediatric drug shortage in China,promote rational clinical drug therapy for children and guarantee the safety of drug use in pe-diatrics.

Objective To explore the influence of psychosocial factor on post partum depression,to offer the theoretical support for intervention on the occurrence of post partum depression. Methods 45 women with the post partum depression as the case group and 84 health women as the control were investigated by using the gravida general situation questionnaire,the Edinburgh Postnatal Depression Scale (EPDS),life event scale (LES),Type A Behavior pattern questionnaire (TABQ),Eysenck Personality Questionnaire (EPQ),Social Support Rating Scale (SSRS),symptom check list-90 (SCL-90),Trait Anxiety Inventory (T-AI) and State Anxiety Inventory (S-AI).

Objective: To investigate the effect of zinc supplementation on expression of MT-1 and MT-2 mRNA in placenta and small intestine of pregnant rats. Method: Eighteen healthy pregnant SD rats were randomly divided into two groups,normal control (ZC) and zinc supplement group (ZS). Rats in both groups were fed the same normal diet. Rats in ZC group drank deionized water and those in ZS group drank the water supplemented with 1.26 mmol/L Zn. At gestational 9.5d and 17.5d, serum zinc was determined by atomic absorption spectrophotometer and the expression of MT-1 and MT-2 mRNA of placenta and small intestine was examined by RT-PCR. Results: Serum zinc levels at gestational 9.5d and 17.5d were higher in ZS group. Relative expression of both MT-1 and MT-2 mRNA in placenta, MT-1 mRNA at gestational 17.5d and MT-2 mRNA at each time point were higher in ZS group. At gestational 9.5d, there was no difference between two groups in expression of MT-1 mRNA. Conclusion: The expression of MT-1 and MT-2 mRNA in placenta and small intestine was up-regulated by dietary zinc supplementation during pregnancy.

Objective:To investigate the effect of zinc supplementation on the expression profile of zinc transporters mRNA in placenta and small intestine of pregnant rats.Method:Eighteen pregnant SD rats were randomly divided into normal control(ZC)and zinc supplement group(ZS).Rats in ZC group drank deionized distilled water while those in ZS group drank water supplemented with zinc of 1.26 mmol/L.Placenta and small intestine were taken at gestational day 9.5 and 17.5,respectively.The expression of ZnT1,2,5 and 6 mRNA was examined by RT-PCR.Results:At gestational D9.5,the expression of placental ZnT1,2 and small intestinal ZnT1,2,6 mRNA was up-regulated,and placental ZnT5 mRNA down-regulated by dietary zinc supplementation.Dietary zinc intake had no effect on the expression of placental ZnT6 and small intestinal ZT5 mRNA.At gestational D17.5,the expression of placental ZnT5 and 6 mRNA was up-regulated by dietary zinc supplementation,and dietary zinc had no effect on the expression of placental and small intestinal ZnT1,2 mRNA.The expression of ZnT5 mRNA at gestational D17.5 in both groups was not detectable.Conclusion:Dietary zinc supplementation during pregnancy has significant effect on the expression profile of ZnT 1,2,5 and 6mRNA in placenta and small intestine of pregnant rats.

This paper is to explore changes of intestinal mucosal barrier, intestinal flora, and bacterial translocation in rats with severe acute pancreatitis (SAP). Twenty four male SD rats were randomly divided into the control group (n = 10) and the experimental group (n = 14). The model of severe acute pancreatitis of rats was induced by the method of injecting adversely 5% sodium taurocholate into the common biliary-pancreatic duct. All of the rats were killed after 24 hours and the level of the serum amylase and the plasma endotoxin was determined after that. The pathological changes of pancreas and small intestine were observed through hematoxylin-eosin staining (HE staining) and the abdominal viscera bacterial translocation rates were tested. With the method of real-time polymerase chain reaction (RT-PCR) the quantity of the intestinal flora was analyzed. In the control group, the level of Escherichia coli, Lactobacillus and Bifidobacterium were 2.08 ± 1.29, 11.04 ± 7.55 and 12.21 ± 4.95, respectively. On the contrast, the level of Escherichia coli in the cecum contents was much higher (9.72 ± 3.58, P < 0.01), while the Lactobacillus number was decreased significantly (0.67 ± 0.34, P < 0.01), and the Bifidobacterium number was also decreased (4.59 ± 3.42, P < 0.05) in the experimental group, so the ratio of Bifidobacterium/Escherichia coli was reversed. Besides, in the experimental group, the plasma endotoxin positive rates and the bacterial translocation rates were much higher (P < 0.01 or P < 0.05) and the pathology scores of pancreas and small intestines were also significantly higher (P < 0.01) than those in the control group. These results indicated that in severe acute pancreatitis rats, the intestinal mucosal barrier was severely damaged and the dysbacteriosis occurs in the intestinal canal. And these might relate to the occurrence and development of multiple organ infection.

OBJECTIVE:To study the protective effects of Li medicine Chushi qufeng decoction on arthritis model rats. METH-ODS:60 rats were randomly divided into normal group,model group,positive group and Chushi qufeng decoction high-dose,me-dium-dose and low-dose groups [45.9,22.95,11.48 g(crude drug)/kg]. Except for normal group,those groups were given chicken type Ⅱ collagen to induce arthritis model. After modeling,normal group and model group were given normal saline intragastrical-ly,once a day,for consecutive 12 d;Chushi qufeng decoction groups were given relevant medicine intragastrically;positive group was given leflunomide 4.5 mg/kg on 1st-3rd day and 1.8 mg/kg on 4th-12th day. The degree of joint lesion in rats were scored. The degree of joint swelling was determined as well as the serum levels of TNF-α,IL-1β and type Ⅱ collagen antibody. RESULTS:Compared with normal group,arthritis index,degree of joint swelling,the serum levels of TNF-α,IL-1βand typeⅡcollagen anti-body increased significantly in model group (P<0.01). Compared with model group,pathological score of positive group and Chushi qufeng decoction high-dose group decreased significantly,and serum levels of TNF-α,IL-1β and type Ⅱ collagen antibody decreased significantly in treatment groups(P<0.05 or P<0.01). CONCLUSIONS:Li medicine Chushi qufeng decoction has cer-tain protective effect on arthritis model rats induced by chicken typeⅡcollagen.

Objective To evaluate the diagnostic value of high frequency ultrasound in sebaceous gland carcinoma of eyelid (SC).Methods The ultrasonic characteristic for 11 cases with eyelid SC were respectively analyzed by using 13 MHz high frequency ultrasound and 22 MHz ultra-high frequency ultrasound.Results Through 13 MHz high frequency ultrasound,in 7 patients who exhibited Pagetoid invasion the lid shin thickness of tumor side displays no significant alteration in a comparison with normal side.Furthermore,the color Doppler flow imaging (CDFI) evealed a branch-like blood flow surrounding the masses in all cases,but the blood flow of seven patients with Pagetoid invasion had no difference compared with the healthy side.On 22 MHz ultra-high frequency ultrasound examination,slit-like low echo was found in 9 ;transition zone of tumor infiltration can be identified in 9 ; the echo of tumors with Pagetoid invasion was lower than the healthy side and the skin thickness of tumors with Pagetoid invasion was thicker (0.6 ±0.1) mm than the healthy side.CDFI revealed that mesh-basket like blood flow was rich in all patients,the small branch blood vessels arrived at subcutaneous,and vasa vasorum were found in some patients.The region with Pagetoid invasion was rich in blood flow.The sonography findings on 13 MHz and 22 MHz high frequency ultrasound examination were compared with chisquare test.There were significant differences on homogeneous echo,slit-like low echo,transition zone of tumor infiltration,infiltration skin thickness,blood distribution,central blood vessels,vasa vasorum,blood flow in the region with Pagetoid invasion (x2 =12.571,15.231,15.231,4.701,22.000,15.231,4.899,10.267,P＜0.05).Conclusions Slit-like low echo in the mass is a main finding of eyelid sebaceous gland cercinoma on the 22 MHz ultra-high frequency ultrasound.The ultra-high frequency ultrasound can accurately reveal the skin depth infiltrated by the eyelid sebaceous gland cercinoma and this method can provide solid guidance for clinical treatment strategies.

Objective To investigate the correlation between plasma cystatin C (CysC) level and carotid atherosclerotic plaque in patients with ischemic stroke.Methods The clinical data in patients with acute ischemic stroke were analyzed retrospectively.According to the results of carotid artery ultrasound,the patients were divided into either a non-plaque group or a plaque group.Then the plaque group was redivided into a stable plaque subgroup and a vulnerable plaque subgroup.Multivariate logistic regression analysis and Pearson correlation analysis were used to explore the risk factors for carotid atherosclerotic plaque.Results A total of 226 patients with acute ischemic stroke were enrolled,172 of them had carotid plaque,and 54 had no plaque.Of the patients with carotid plaque,94 were stable plaque and 78 were vulnerable plaque.The age (71.82 ± 9.94 years vs.60.74 ± 13.81 years; t =6.160,P =0.014),proportion of patients with ischemic heart disease (11.6％ vs.1.9％; x2=6.169,P=0.020),systolic blood pressure (148.770± 21.007 mm Hg vs.142.240 ± 19.404 mm Hg; t =2.029,t =0.044),plasma CysC concentration (1.046 ± 0.438 mg/L vs.0.860 ±0.214 mg/L; t =3.006,P =0.003),and carotid IMT (1.122 ±0.278 mm vs.0.878 ±0.250 mm; t =5.762,P=0.000) in the plaque group were significantly higher than those in the non-plaque group.Multivariate logistic regression analysis showed that the age (odds ratio [OR] 1.079,95％ confidence interval [CI] 1.044-1.116; P=0.000) and IMT (OR 31.450,95％ CI 6.233-158.692; P=0.000) was the independent risk factor for carotid plaque,while there was no significant independent correlation between the plasma CysC level and carotid plaque (P =0.217).Only IMT in the stable plaque subgroup was significantly higher than the vulnerable plaque group (1.176 ±0.285 mm vs.1.058 ±0.258 mm; t =-2.824,P =0.005),and it was the independent protective factor for the carotid plaque stability (OR 0.195,95％ CI 0.059-0.064; P =0.007).Pearson correlation analysis showed that the plasma CysC level was positively correlated with the age (r =0.375,P =0.000) and serum creatinine level (r =0.462,P =0.000),but it was not significantly correlated with carotid IMT (r =0.075,P =0.264).Conclusions In patients with ischemic stroke,no correlations were found between the plasma CysC level and carotid atherosclerotic plaque,plaque stability,and IMT.
