OBJECTIVE: To establish a HPLC method for the assaying of fluoxetine in microdialysate in rat's brain by HPLC. METHODS: Fluoxetine, which was extracted with N-hexane, was separated on ODS chromatographic column after derivatization by NBD-COCl,acetonitrile-water (50∶50) was the mobile phase with a flow rate of 1.2ml/min, column temperature of 35℃,fluorescence detection wave length ?ex at 478nm and ?em at 537nm. RESULTS: The linear range for fluoxetine in microdialysate in rats' brain was 10～100 nmol/L(r=0.9 996), and the quantitation limit was 10 nmol/L. CONCLUSIONS: The method is specific, sensitive and accurate,it is suitable for the assaying of fluoxetine in biological specimen.

Objective To observe the curative effect of acupoint injection of compound Danshen injection in the treatment of nonneoplastic epithelial disorders of vulva.Methods 96 patients with vaginal epithelial non tumor like lesions were enrolled in this study,including 38 cases of squamous epithelial hyperplasia,lichen sclerosus in 42 cases,lichen sclerosus associated with squamous cell hyperplasia in 16 cases.Take Zhōngjí,Guīlái,Huìyīn, Sānyīnjīao,Zhàohaǐ,and Tàichōng six points,each acupoint injected compound Danshen injection 2mL,injected twice a week,10 times for a course of treatment,after 2 weeks began next course of treatment,a total of three courses.The clinical curative effect and incidence of adverse reaction of three types of nonneoplastic epithelial disorders of vulva were compared.Results The effective rates (effective rate =clinical control +effective +valid)of three types of epi-thelial disorders of vulva tumor like lesions were squamous epithelial hyperplasia 92.11%,lichen sclerosus 90.48%, hardening of lichen planus associated with squamous cell hyperplasia 87.50%,there was no significant difference among the three types of lesions(χ2 =4.102,P >0.05).The total effective rate of three types of nonneqlastie epithe-lial disorders of tumor was 90.62% by acupoint injection,and there were no serious adverse reactions in all patients during therapy.A patient of lichen sclerosus appeared the symptoms of nausea,sweating during treatment due to nerv-ous,and after psychological guidance the symptoms disappeared,re -treatment did not appear.Conclusion The acu-point injection of compound Danshen injection in the treatment of vulvar intraepithelial non -tumor like lesions has better clinical effect,and has no serious adverse reactions.

It is the traditional virtue of Chinese to be honest, and honest-trust is the foundation of the development of market economy. The phenomenon of honest-trust lacking in the field of medical care is a comprehensive result for many factors. It's a new subject to advocate sincere service and spread honest-trust culture for the construction of medical ethics. Therefore, we should put emphasis on the medical ethics education, strengthen the consciousness of sincere service, perfect the criteria of medical ethics, and set up the credit system of medical organization and medical staff.

Establishing harmonious physician-patient relationship is importamt to set up the harmonious society.Some hospitals try in recent years a line the single disease grows the price control charges,which suggest its importamt role in seting up harmonious physician-patient relationship,and greatly attract public's concern as the new measure in this aspect.

This paper expounds four demands of connotation in higher creative education,and summarizes the creative education practice of Harbin medical university in five fields,which involves establishing creative educations base,establishing scientific research item,setting up network teaching platform,promoting teaching method and enhancing professional ability of teachers.

High mobility group box l protein (HMGB1) is a highly conserved non-histone DNA binding protein,which is widely distributed in eukaryotic cells.HMGB1 is an important proinflammatory cytokine,involving in various pathological and physiological processes,such as inflammation,neurogenesis and angiogenesis.In the early stage of intracerebral hemorrhage,HMGB1 can induce secondary brain injury,such as inflammatory reaction,neuronal necrosis,and brain edema.However,in the late stage of intracerebral hemorrhage,HMGB1 can promote angiogenesis and neurogenesis,and thus improving neurological function.HMGB1 will become a novel therapeutic target for intracerebral hemorrhage in the future.

Objective:Investigate the awareness of their own rights and the safeguarding of the rights in practice,raise the patients' sense of safeguarding of the rights and help them defend the legal rights.Methods:A survey was taken among patients by applying the questionnaire.Results:There are 5 items about the patients' knowledge about their own rights and 3 items about defending their rights in practice,in which more than 85 percent of 111 patients chose the answer "always or almost".From this we can see that the awareness and safeguarding of their rights are not good enough.Conclusion: The government is appealed to break up the existence of the monopoly mold in medical treatment and to take measures to protect the rights of patients.The medical personnel should renew their concepts,pay more attention to publicizing and defending patients' rights,and help patients realize their rights.

0.05). Conclusion: Spironolactone could not enhance or inhibit the growth of hair follicle.

Objective To screen extraction process for Rosae Laevigatae Fructus.Methods With the content of total saponins and total phenolic acids from Rosae Laevigatae Fructus as the evaluation indexes, ethanol concentration, extraction time, solid-liquid ratio and extraction times as investigation factors, the test data were analyzed by Design-Expert8.0.5 software, and a multiple quadratic regression equation was set up to screen extraction process parameters of Rosae Laevigatae Fructus.Results The best extraction process parameters of Rosae Laevigatae Fructus were as follows:ethanol concentration was 62.79%;solid-liquid ratio was 13.12:1;the extraction time was 137.93 min;extraction times were 1.85 times. Considering the convenience for actual operation and the practicability of industrial production, the extraction process parameters should be ethanol concentration of 60%, revised solid-liquid ratio of 13:1, 2 hours' extracting time, and 2 extraction times.Conclusion Final selected parameters provide the basis for the extraction process of Rosae Laevigatae Fructus.

Objective To investigate the effect of thalidomide and As_2O_3 to the secretion of VEGF of the cell of ANLL and study if there is coorperation in thalidomide and As_2O_3.Methods From October 2001 to February 2003,23 patients with ANLL were analyzed.Heparinized marrow was taken,then it was putt into Ficoll-isopaque solution to be purified for MNC,which was cultured in the RPMI 1 640 medium,placed in 5% CO_2 saturation and 37℃ to proliferation.Choosing the cells in logarithm growth phase,adding cultural solution to abstaining the cellular density of 2?10~9/L and then putting it into 24-well plates.There are 4 groups :contrast group,thalidomide(300 ?g?mL~ -1 )group,As_2O_3(25 ?mol/L)group,and thalidomide(300 ?g?mL~ -1 )andAs_2O_3(25 ?mol/L)group,cultured for 72 hours.Examine the concentration of VEGF in upper liquid with ELISA method.Results The concentration of VEGF in upper liquid of 4 groups were respectively(1 582.67?281.51)ng/L、(1 206.29?264.87)ng/L、(941.72?236.34)ng/L、(639.12?211.98)ng/L.There were statisticd difference(P
