Objective To investigate the low back pain(LBP)of clinic nurses and find out the understanding of related knowledge of LBP in nurses,and improve the occupational protection of nurses.Methods Investigation was carried out in 692 nurses by self-designed questionnaires.Results The incidence of LBP in nurses was 97.4%.The knowledge of LBP and the related occupational protection in nurses were greatly deficient.Conclusions The hospital should pay attention to the protection of LBP in nurses and improve their health.

OBJECTIVE: To provide references for domestic drug manufacturing enterprises' participation in laboratory accreditation as well as the enhancing of drug analysis capability. METHODS: Both international and domestic laboratory-ratified standards, the importance of laboratory accreditation and drug manufacturing enterprises' participation in laboratory accreditation were expounded. RESULTS & CONCLUSIONS: Domestic drug manufacturing enterprises' participation in laboratory accreditation is conducive to the enhancing of their drug analysis capability.

OBJECTIVE:To provide references for Chinese pharmaceutical enterprises in developing commissioning manufacture of overseas drugs.METHODS:The registration system of medicine commissioning manufacture in China,Japan and other countries were compared.The current status of Chinese drugs commissioning manufacture and the feasibility for Chinese pharmaceutical enterprises to gain commissioning manufacture of overseas drugs were analyzed.RESULTS & CONCLUSIONS:Both the government and pharmaceutical enterprises in China should take advantage of the amendment of the pharmaceutical affairs Law in Japan to contribute to the development of commissioning manufacture of overseas drugs.

Objective To know the ability of degrading oxalate of three species of Lactic acid bacterium and their mixing bacteria coming from yoghurt in vivo culture broth. Methods Identifying the species of Lactic acid bacteria obtained from 6 brands of yoghurt.Three species of bacterium and their mixture was cultured separately for 72 h in MRS broth which contained three different concentration of ammonium oxalate,and the broth without inoculum of bacteria was prepared as a control.The concentration of ammonium oxalate in culture were detected. Results Three species of Lactic acid bacteria (L.bulgaria,L.acidophilus and L.thermophilus) were detected in every band of yoghurt.After 72 h incubation,the concentration of oxalate in all the broth containing bacteria was lower than that in the control ones.L.acidophilus showed the best degrading activity,and in the presence of ammonium oxalate 5 mmol/L,the 11.0% of oxalate was degraded by the bacteria.The higher concentration of oxalate was,the more the amount of oxalate degraded was,but the lower the percent of degrading was. Conclusions All the species coming from yoghurt have the ablitiy of oxalate degrading which become greater as the increasing of the concentration of oxalate in culture.

Objective: To observe the effect of different caesalpinia sappan extract on the Mice thymus tissue, peripheral T-cell proliferation and the production of INF-?. Methods: To make preparation of different caesalpinia sappan extract and give them to the mice, weighing the mice thymus and calculating the thymus index 7 days later. The MTT method was used to measure the proliferation ability of T-cells of the mouse spleen. A double antibody sandwich ELISA was used to detect INF-? content in T-cells culture supernatant. Results: The different caesalpinia sappan extract not only have clear inhibitory effect on the weight of thymus but also have inhibitory effect on the proliferation of T-cells and the production of INF-?. The inhibitory effect of caesalpinia sappan ethanol extract and n-butanol extract on the T-cells is much stronger.

Objective: To determine the maximal tolerance of Xunengda Tablets on mice and explore curative effects of its antithrombotic effect and provide the theoretical basis for selecting drugs. Methods:Mice were given maximal dose, 26g?kg -1 of body weight, XND Ig once; Divided 53 mice into five groups, they were administered XND tab.(3g?kg -1 ), RSC(1.25g?kg -1 ), CDDP(1.25g?kg -1 ), XSTL(2.5g?kg -1 ), and NS once daily for 7 days, repectively; 1h after treatment the seventh day, the animals of groups iv. were given collagen adr by producing whole organism thrombus, observing the mortality, They were determined coagulation time with the blood capillaries and the number of writhings per mouse was recorded in order to determine pain. Results:Maximal tolerance (Ig) is 26g?kg -1 , 886.7 times the dose of clinical application apart from XSTL, three kinds of drug showed the avidence of antithrombotic effect ( P

Objective To establish the determination method of Paeoniflorin in Xiaoshuan pills. Methods Extract solvent and time was studied by HPLC method. The HPLC system consisted of Lichrospher C18 column (5 ?m,150 mm?4.6 mm) and methanol-water (30∶70) as the mobile phase. The detective wavelength was 230 nm, the flow rate was 1.0 mL/min, and the temperature was 25 ℃. Results The powder of Xiaoshuan pills was extracted with methanol. The Paeoniflorin was linear within the range of 0.051～0.510 mg/mL, the average recovery was 98.37%, and RSD was 3.13%. Conclusion The method is simple, highly exclusive, and suitable for quality control of Xiaoshuan pills.

Objective To investigate the effect of alternating shift on general well-being of nurses,and analyze its relationships with related factors. Methods Alternating shift nurses from general hospi-tals above courty-level in Liaocheng city who were engaged in clinical work were selected by duster sam-pling.Questionnnires were sent out and later gathered. The investigation tools included general well-being schedule(GWB) ,marital quality inventory, social support inventory, Eysenck personality questionnaire were used in survey. Results (1)There was difference in the score of general well-being between nurses with different ages and professional titles(P<0.01). (2)There was significant difference between GWB and oth-er factors such as marital quality,EPQ (psychoticism, neuroticism and introversion and extroversion), so-cial support(P<0.01). (3)Multivariable linear regression which took general well-being as dependent vari-able, the variables which entered the equation were neuroticism, family relationship,support utilization,psychoticism, objective support, introversion and extroversion, marriage satisfaction,arrangement of econ-omy. Conclusions (1)The older, the higher of professional tltles,the stronger general well-being of nurses. (2)Sabjective well-being and marital quality, social support, lying defense were positively corre-lated; neuroticism, psychoticism were negatively correlated. (3)Neuroticism, family relationship,support and utilization, psychoticism, objective Support, introversion and extroversion, marriage satisfaction,ar-rangement of economy can affect general well-being,among which neuroticism had great influence.
