OBJECTIVE:To provide reference for improving the service quality of outpatient pharmacy in hospital. METH-ODS:A questionnaire survey was conducted to investigate and analyze the patients’satisfaction and related influential factors to outpatient pharmacy in a third grade class-A hospital in Chengdu. RESULTS:Totally 165 questionnaires were sent out,and 150 were effectively received with effective recovery of 90.91%. The total score for patients’satisfaction was (44.67 ± 7.81) scores, and the rate of satisfaction was(81.22±14.19)%. The top three entries were“the will you choose to come to our hospital again if necessary”,“the notices about time and place for taking the medicine”and“the overall evaluation of the professional ethics of med-ical staff”,scored 4.38,4.25 and 4.25,respectively;the last three entries were“waiting time for taking medicine”,“the notices about how long it takes to take the medicine”and“service facilities and environmental facilities for drug taking”,scored 3.55, 3.63 and 3.95,respectively. The top three suggestions were“long waiting time for taking medicine and inconvenient”,“noisy envi-ronment,bad order”and“expensive drugs charges but less reimburse”. The univariate analysis and multivariate analysis showed that gender,age,marital status,education,occupation,family income per month,resident,drug taking times and payment etc. factors showed no significant effects on patients’satisfaction scores(P>0.05). CONCLUSIONS:The degree of patients’satisfac-tion in outpatient pharmacy have no obvious specificity and preference,the key to improve the degree of satisfaction lies on strengthening the service of the hospital and the perception of the patients. While the next research will focus on how to find the breakthrough points and key points to improve the experience of waiting,standardize process management and logistics manage-ment,and make patients aware of the service development.

Objective To investigate the effects of probiotics on the occurrence of ovalbumin (OVA) induced food allergy and the regulatory effects on immune function of rat models. Methods Thirty female Brown-Norway rats aged 3 weeks were randomly divided into blank control group,food allergy group and probiotics intervention group(n=10).The levels of serum OVA-IgE and intestinal sIgA were measured by ELISA method.Splenic lymphocytes were isolated and cultured in vitro,and the Treg lymphocyte subgroups in the spleen were analyzed by flow eytometry.The levels of IFN-γ,IL-4 and IL-10 in the supernatant of cultured splenic lymphocytes were measured by ELISA method. Results The serum OVA-IgE level in food allergy group was significantly higher than that in blank control group(P<0.05),while that in probiotics intervention group was significantly lower than that in food allergy group(P<0.05).Compared with food allergy group and blank control group,the level of intestinal sIgA in probiotics intervention group was significantly higher(P<0.05).The percentage of CD4~+CD25~+T lymphoeytes in food allergy group was significantly lower than that in blank contml group(P0.05).The levels of IL-4 and IL-10 in food allergy group were significantly higher than those in blank control group(P<0.05).Probiotics intervention group had significantly lower levels of IL-4,IL-10 and IFN-γ than food allergy group(P<0.05).The ratio of IFN-γ/IL-4 in food allergy group was significantly lower than that in blank control group(P<0.05),while that in probiotics intervention group was significantly higher than that in food allergy group(P<0.05). Conclusion Probioties intervention could prevent the occurrence of food allergy in animal models by modulating the Th1/Th2 eytokine balance.

Objective To investigate the effect of standardized usage of antibiotics and hand hygiene on carbapenem-re-sistant Enterobacteriaceae (CRE) infection in neonates. Methods According to the situation of standardized management of an-tibiotics in our hospital, the study period, from January 2011 to December 2013, was divided into pre-intervention, transition and post-intervention. Retrospective study was employed to analyze the antibiotics use density (AUD), the hand hygiene compliance rate among the medical staff, the positive rate of CRE and the nosocomial infection percentage of the neonatology department. Results From pre-intervention to post-intervention period, the AUD was decreased from 12.93 DDDs to 8.10 DDDs;hand hy-giene compliance rate of medical staff was increased from 53.49%to 83.33%;the detection rate of CRE was decreased from 3.71%to 2.27%. The differences were all signiifcant among different periods (P<0.01). The nosocomial infection percentage decreased from 0.22%to 0.17%and there was no signiifcant difference (P=0.441). Conclusions Standardized usage of antibiotics and hand hygiene can be served as economical yet effective approaches to controlling CRE infection in neonates.

Objective:To study the effect of Longman Ampelopsis grossedentata on the level of serum lipid. Methods:The exper-imental rats were given high-fat diet during the experiment. The rats were randomly divided into the model group, high dose group (37. 80 g·kg-1), medium dose group (12. 60 g·kg-1), low dose group (6. 30 g·kg-1) and lipid-lowering drug group (180 mg· kg-1 ) . All the groups were administrated continuously for 30 days, and the effect on body weight, serum TC, TG and HDL-C were measured. Results:Compared with that of the model group, the increase of body weight in the other groups was not significant ( P>0. 05), and all the rats had no obvious poisoning symptom. TC and TG were higher after the high-fat diet administration than those be-fore the experiment in the model group, and the differences were statistically significant (P<0. 05). After the 30-day treatment, the levels of TC and TG in the high-dose group were significantly decreased compared with those of the model group (P<0. 05). Conclu-sion:Longman Ampelopsis grossedentata shows assistant therapeutic effect on serum lipid.

Objective To evaluate CTA characteristics of anomalous origin of coronary artery from the pulmonary artery (ACAPA).Methods The clinical data of 24 patients with ACAPA were retrospectively analyzed,and the results of CTA were compared with operation.Results In 24 ACAPA cases,20 cases (20/24,83.33％) occurred in the left coronary artery (LCA),1 case (1/24,4.17％) was in the right coronary artery (RCA),1 case (1/24,4.17％) was in the anterior descending artery (LAD) and 2 cases (2/24,8.33 ％) were in the circumflex artery (LCX).The origins of coronary anomalies originated from the posterior wall of the pulmonary sinus or pulmonary trunk in 11 cases (11/24,45.83 ％),left wall in 7 cases (7/24,29.17％),right wall in 4 cases (4/24,16.67％),originated in the left pulmonary artery in 2 cases (2/24,8.33％).Collateral circulation:Infant type was in 5 cases,no collateral vessels between the coronary artery was observed;adult type was in 19 cases,of which 16 cases were of abnormal origin of the LCA and RCA,1 case was of LAD,2 cases were of LCX.The double LAD and coronary arteries with an intramural segment were found in 1 case respectively.Surgery were performed in 19 cases.Five cases were reviewed by CTA,1 case with anastomotic stenosis of LCX,1 case with restenosis of right ventricular outflow tract and 1 case with coronary pseudoaneurysm.Conclusion CTA can clearly show the origin of abnormal coronary artery,the distance from the ascending aorta,collateral vessels,combined with other coronary artery malformations,which can help surgical preparation of preoperative surgical approach,and postoperative follow-up.

This study examined the impacts of intrauterine murine cytomegalovirus (MCMV) infection on the long-term learning and memory of offspring. Sexually matured male and female BALB/C mice without MCMV infection were identified by ELISA and then mated. Seventy pregnant mice were randomly divided into the virus group (n=40) and the control group (n=30), in which the pregnant mice were subjected to placenta inoculation of MCMV suspension (1 μL, 1×106 PFU) or the same amount of cell culture medium, respectively, at gestational age of 12.5 days. Some pregnant mice [virus group (n=20), control group (n=15)] were sacrificed by cervical dislocation at gestational age of 18.5 days, and the head circumference and brain weight of the mouse fetuses were measured, and the MCMV infection in their brain tissues was detected by PCR. The other pregnant mice [virus group (n=20), control group (n=15)] delivered naturally, and the learning and memory capability of the offspring at 70-day-old was analyzed by Morris water maze test. The results showed that 28.57% mouse fetuses in the virus group developed viral infection in the brain. Their head circumference and brain weight were significantly reduced as compared with those in the control group (P<0.01). The Morris water maze test revealed that the mouse offspring in the control group found the platform with straight-line trajectories after training. In contrast, the counterparts in the virus group intended to enter the central area, but looked for the platform with a circular trajectory. And the infected mice exhibited prolonged swimming distance and swimming latency (P<0.01). It was concluded that: (1) placenta inoculation of MCMV can cause fetal brain infection and intrauterine development retardation; (2) the offspring of MCMV placenta inoculation mice showed a long-term decline in learning and memory capability.
