OBJECTIVE:To establish a new semi-automatic drug dispensing mode,with proper cost,which falls in between full-automatic drug dispensing mode and manual drug dispensing mode,good work efficiency,standard and simple operation meth-od and meets national laws and regulations. METHODS:A semi-automatic drug dispensing system was designed,in which the in-formation in the drug dispensing sheet could be automatically printed on the drug bag,and automatic bagging,packaging and deliv-ery of drugs were realized. Such drug dispensing system included hardware(mechanical structures such as drug turntable and drug funnel,transmission device,etc.)and software control systems(the program of interface with hospital information system,micro control unit software,computer software,etc.). Through commissioning,formal operation and statistics,based on 18 oral drug dis-pensing sheets with the same contents,calculated the time of drug dispensing and the number of drug dispensing errors by 3 phar-macists respectively in manual drug bag dispensing mode and semi-automatic drug dispensing mode,to evaluate the effect of the semi-automatic drug dispensing system. RESULTS:From commissioning in May 2012 to formal operation in September 2012,the system operated normally and utility model patents were obtained. In the two modes,the total time of drug dispensing was 481 and 397 min (t=6.82,P<0.001),the numbers of drug dispensing errors were 25 and 7 (χ2=9.353 8,P=0.002 2),respectively. There was statistical significance. CONCLUSIONS:The semi-automatic drug dispensing system has higher efficiency and less num-ber of drug dispensing errors compared with manual drug bag dispensing mode and lower cost compared to full-automatic drug dis-pensing system. It deserves promotion.

Objective To study the differences in retinoic acid receptor γ(RARγ) mRNA expression levels in blood leukocytes between antipsychotic-free and antipsychotic-naive schizophrenic patients and healthy control,especially in different genders. Methods Forty-three acute schizophrenic patients who were antipsychotic-naive or antipsychotic-free for at least three months (male = 34, female = 9) and 39 age- and sex-matched healthy subjects (male =25 ,female = 14) were included for blood leukocytes expression of RAR γ mRNA ,using real-time PCR technique. Results Kolmogorov-Smirnov Z analysis showed a significant increase of RARγ mRNA (P =0.041) level in blood leukocytes of pooled schizophrenic patients(0. 027 ± 0. 003) than in the healthy subjects (0. 020 ± 0.002). The elevation was mainly found in the female patients (0. 030 ± 0.003). Within-sex analysis showed that the female schizophrenic patients showed a trend increase (P = 0. 166) of RAR γmRNA expression compared with the male patients (0. 026 ± 0. 001) and exhibited greater RARγ mRNA expression (P = 0. 014)when compared with the female healthy subjects(0. 018 ±0.004). Conclusions The present findings showed an abnormal expression of leukocyte RARγ mRNA level in antipsychotic-free and antipsychotic-naive schizophrenia especially in the female patients. Blood RARγ markers could add to the diagnosis and individualized pharmacotherapy of schizophrenic patients ,especially the female patients.

OBJECTIVE: The purpose of this study is to observe the affection of different clinical surgeries on alar nasal cartilages' growth and development. The experimental results can provide some theory basis for clinical surgeries. METHOD: Twenty-eight New Zealand immature rabbits were used in this study, and divided into normal control group, hidden dissection group and cutting off alar nasal cartilages group randomly, which included 4,12 and 12 rabbits, separately. Arc incision were made on the mucous membrane of nasal cavity,and then dissect the alar nasal cartilages hidden or cut off the alar nasal cartilages, separately. The growth and development of the alar cartilage were observed at different stages after the surgery using histological and immuno-histochemical methods. RESULT: Four weeks, eight weeks, twelve weeks and sixteen weeks after surgery, there were no significant differences in the indexes of chondrocytes between hidden dissection group and control group. In cutting off alar nasal cartilages group, fiber tissue were observed in the vacancy left after being cut off cartilages, and even mucous membrane tissue could be seen in some slices. CONCLUSION There is no adverse influence on the growth and development of the alar cartilage after being hidden dissected. Contrarily, the restoring capability of transparent cartilage cannot counteract the injury resulted form the surgery after the alar nasal cartilages being cut off.

Objective To determine the current situation of radiological health management in medical institutions in Nanyang, China, to analyze existing problems and propose improvement measures, and to improve the management level of radiological diagnosis and treatment practice in medical institutions. Methods According to the work plan of the Occupational Disease Prevention and Control Project in Henan Province, China, 66 medical institutions engaged in radiological diagnosis and treatment at different levels were selected for a questionnaire survey, in combination with on-site inspections, inquiries, and access to relevant materials. Results Of 66 medical institutions, 65 institutions held radiological diagnosis and treatment licenses, with a license holding rate of 98.5%. There were 17 “new construction, reconstruction, and expansion” projects, with an evaluation rate of 94.1%. In this survey, a total of 391 radiological diagnosis and treatment equipment were involved, and 387 units of equipment were tested for status, with a detection rate of 99.0% and a qualification rate of 94.8% (367/387); 55 units of equipment were tested for stability, with a detection rate of 14.1%; the workplace protection detection rate was 99.0%, and the qualification rate was 100%; 66 medical institutions had 1809 radiation workers, with an occupational health examination rate of 97.8%; 1262 people were trained, with a training rate of 95.7%; 1773 people were monitored for individual dose, with a monitoring rate of 98.0%. Conclusion Medical institutions should further strengthen management in licensing change, construction project evaluation, and equipment stability monitoring to improve the level of radiological health management.

Objective To examine the effect of ground cage use on Oncomelania hupensis spread, so as to provide insights into precision snail control. Methods Twenty ground cages that were frequently used to capture rice field eels were purchased, including 11 packaging tape-made cages, 7 plastic cages and 2 nylon rope-made cages. The eel-capturing activity was mimicked, and 20 ground cages were assigned in settings with relatively high (1.00 snail/0.1 m² and higher) and low snail densities (< 1.00 snail/0.1 m²) in Xindai Township, Pinghu City, Zhejiang Province during the period from 15 : 00 to 8 : 00 of the following day on April 13, 26 and 28. The numbers of snails carried by different types of ground cages were compared in settings with different types of snail densities using the rank-sum test. Results A total of 11 cage-times were assigned in settings with a high snail density, and a total of 77 snails were captured, with a mean number of 7 snails in each cage-time and 2.15 snails in 0.1 m² ground cage. The mean numbers of snails carried by packaging tape-made and plastic cages were 2.47 snails/0.1 m² cage and 0.37 snails/0.1 m² cage, respectively. A total of 24 cage-times were assigned in settings with a low snail density, and a total of 8 snails were captured, with a mean number of 0.33 snails in each cage-time and 0.09 snails in 0.1 m² ground cage. The mean numbers of snails carried by packaging tape-made cages were 0.12 snails/0.1 m² cage; however, no snails were carried by plastic or nylon rope-made cages. The number of snails carried by ground cages was higher in settings with a high snail density than in settings with a low snail density (Z = −4.019, P < 0.01), and the number of snails carried by packaging tape-made cages was higher in settings with a high snail density than in settings with a low snail density (Z = −4.086, P < 0.01). No significant differences were found in the numbers of snails carried by different types of ground cages. Conclusion The use of ground cage in snail habitats is a contributor to snail spread.

OBJECTIVETo investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus (GDM).

METHODSA total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation (WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity.

RESULTSAge, pre-pregnant body weight (BW), and body mass index (BMI) were associated with increased risk of GDM. Fat mass (FM), fat mass percentage (FMP), extracellular water (ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass (FFM), muscular mass (MM), and intracellular water (ICW) were associated with a decreased risk of GDM.

CONCLUSIONMaternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity.
