Food Sanitation Law which was issued for many years has no longer been congruent with the current development of socio-economy. Under this situation,Food Safety Law came into being. Although the promulgation of the law is important,the task of carrying out the law is more difficult. On the basis of concluding the problems in carrying out the food sanitation law and the analysis of its causes,it is significant to discuss the Food Safety Law from the viewpoint of Food Sanitation Law enforcement.

Objectiv To evaluate the usefulness of dot immuno-gold filtration assay(DIGFA) for the diagnosis of Paragonimus infection.Methods During 2003 to 2006,72 cases suspected of paragonimiasis in Zhejiang Province were examined with DIGFA for rapid detection of specific antibodies against Paragonimus(Pw-DIGFA).The diagnosis was primarily established with the presence of antibodies,experience of ingesting raw freshwater crabs or crayfishes and clinical presentations.The cases were treated with praziquantel and followed-up at 3 and/or 6 months post-treatment.Antibody level in patients(pre-and post-treatment) were detected in parallel and analyzed comparatively by Pw-DIGFA and ELISA.Results The result of detection by Pw-DIGFA was in agreement with that of ELISA.28 of 72 cases were antibody positive and 44 cases were negative.Among the 28 positives,26 cases had a history of eating raw freshwater crab or crayfishes and the other 2 cases drank freshwater from brook before.21 cases showed paragonimiasis-related clinical symptoms such as low-grade fever,cough,or changes in image examination,while the other 7 cases showed only eosinophilia in peripheral blood(15%-70%).The mean absorbance values(A450) of positive sera,negative sera and normal sera tested by ELISA were 1.7361,0.2973 and 0.2657 respectively.There was significant difference between the positive cases and the negative cases(t=12.047,P0.05).At 3 month post-treatment,serum antibody in 5 cases whose clinical symptoms and physical signs relieved or disappeared decreased 2-5 titers and that of one case who relapsed with new signs increased by one titer.In Pw-DIGFA,the dot color of 5 cured cases showed a little weaker than that of pre-treatment and the relapsed case displayed similar response.At 6 month post-treatment,7 sera of clinically cured cases showed significantly weaker response than that of pre-treatment.The antibodies of those sera dropped 3-6 titers.Conclusion Pw-DIGFA is of supplementary value for clinical diagnosis of paragonimiasis.Antibody detection by pre-and post-treatment using Pw-DIGFA shows potential for the evaluation of therapeutic effect.

Objective To investigate effects of Ginkgo biloba extract(EGb) on expression of CREB and pCREB in cortex of aging rats.Methods Male Wistar rats were divided into three groups:young control group,old control group and EGb group.Rats in EGb group were treated with intragastric administration of EGb,while rats in the other two groups were treated with distilled water.The spatial learning and memory were evaluated by Morris water maze,and the expression of CREB,pCREB were detected by western blot.Results( 1 ) Compared with young control group (9.6 ± 2.88,41.55 ± 6.30),the swimming time and times through platform in the target quardrant of rats in old control group(6.8 ± 2.49,34.92 ± 4.56) were reduced (P ＜ 0.05 ).The times passing through the platform and the time exploring the target quadrant were more and longer in EGb group(9.4 ± 2.63,41.0 ± 6.68 ) than those in old control group(P ＜ 0.05 ).(2)Compared with rats in young control group( 1.07 ±0.33,0.26 ± 0.04),relative contents of CREB and p-CREB proteins in cortex (0.70 ± 0.21,0.13 ± 0.05 ) weredecreased in old control group(P＜0.05 ).CREB and p-CREB Levels were higher in EGb group ( 1.02 ±0.18,0.18 ±0.02)than those in old control group(P ＜ 0.05 ).Conclusion EGb can ameliorate spatial learning and memory of rats by increasing the expression of CREB and p-CREB in cortex.

In order to clarify the chemical composition and source of Banxia Xiexin decoction quickly and comprehensively, whole and individual herbs of Banxia Xiexin decoction were analyzed by ultra-performance liquid chromatography with quadrupole-time-of-flight mass spectrometry (UPLC/Q-TOF-MS(E)). Under identical experiment conditions, chromatography results were compared between experiment groups. Based on the Q-TOF-MS(E) analysis, 74 peaks were identified on line. The herbal sources of these peaks were assigned. The results implied that flavonoids, triterpenoid saponins, alkaloids and glycosides were the main components in effective part of Banxia Xiexin decoction. The method established is simple and rapid for elucidation the constituents of Banxia Xiexin decoction and the results could be used for the quality control of Banxia Xiexin decoction.

Objective To investigate and analyze the attitudes towards interprofessional learning among nursing students and medical students,and thereby provide basis for interprofessional education (IPE).Methods Readiness of Interprofessional Learning Scales (RIPLS) were used to investigate 107 nursing students in the third grade and 80 medical students in the fourth grade.A comparison analysis of interprofessional learning was carried out among nursing students and medical students.Results Nursing and medical students' mean scores of RIPLS were (4.48±0.42) and (4.27±0.36),respectively.Nursing students' scores of RIPLS and professional identity were significantly higher than those of medical students.Conclusions Nursing students in the third grade and medical students in the fourth grade both have a positive attitude towards interprofessional learning,so IPE is expected to carry out at these stages to achieve good teaching effect.Meanwhile,for the medical students,it may be appropriate to increase the proportion of humanities and social science courses,increase opportunities to participate in clinical practice,in order to facilitate the improvement and development of their professional identity and interdisciplinary learning attitude,and better implementation of IPE.

0.05). Among 36 sera collected at 12 months post-treatment, the antibody negative conversion rates were 80.6% (29/36) and 58.3% (21/36), there was a significant difference between the two assays (P

Objective:To study the varieties and contents of related substances in cefalotin sodium by HPLC and MS. Methods:The quantitative determination of impurity spectra was carried out using self-contrast method, and UPLC-MS was used to preliminarily i-dentify the variety of impurities. Results:Through the study on the ascription and content of the related substances, there were 6 sub-stances existing in cefalotin sodium, and through the structure analysis, the 6 substances showed antibiotic action and toxicity. Conclu-sion:The method is simple, stable and repeatable, which can be used for the determination of cefalothin sodium and related sub-stances.
