Objective To propose a method for the determination of droxidopa concentration in human plasma by HPLC method for the study of the pharmacokinetics of droxidopa.Methods After a single oral dose of 200 mg droxidopa capsule was administered to 12 healthy Chinese male volunteers,we used perchloric acid to precipitate proteinum and then determined the droxidopa concentration in plasma by HPLC.The pharmacokinetic parameters of droxidopa were calculated by 3P87 software.Results The linear range was 0.025-2 ?g/ml.Pharmacokinetic parameters were: T1/2(108.50?30.78)min,AUC(185.74?26.41) ?g?ml-1?min-1,CL(1.08?0.08)ml/min,Tmax(99.90?10.05)min,Cmax(0.74?0.08)?g/ml.At 10 h after administration,droxidopa was eliminated from the blood almost completely.Conclusion The method we proposed is sensitive,reproducible,and easy to operate.Pharmacokinetics of droxidopa in vivo is fitted to two-compartment model.

The writing of vocational college thesis is the maln way to test whether the students are able to analyze and solve practical problems with the professional knowledge and skills they've learnt, as well as improve the capability of production and practice. This paper analyzes the present situation of the thesis written by higher vocational college students majoring in pharmaceutical sci-ences, and figures out the four kinds of evaluation standards about graduation thesis for students in various pharmaceutical fields with different problems. The four kinds of evaluation standards includes key point analysis on Standard Operation Procedure (SOP), planning strategy for pharmaceutical mar-keting, investigation of rational use of drugs in hospitals and subject research. The author puts forward the solving method for the problem, and formulate the evaluation requirements.

Objective To investigate the changes of plasma cortisol and adrenocorticotrophic hormone(ACTH)levels in prema-ture neonates with the infectious diseases.Methods Ninety premature neonates in the neonatal department of our hospital were di-vided into the control group(30 cases),mild infection group(30 cases)and severe infection group(30 cases).The radioimmunoassay was adopted to detect the serum cortisol and ACTH levels on 1,3,7 d after birth in all subjects and the corresponding comparison was conducted.Results The cortisol levels on 1,3,7 d in the mild infection group were (193.04 ±39.48),(151.12 ±35.62 ), (128.37±27.47)ng/mL respectively,the level on 1 d was higher than that on 3,7 d (P <0.05),and the 3 d was higher than that on 7 d (P <0.05).The cortisol level on 1,3,7 d in the severe infection group were (99.43±50.17),(96.52 ±44.69),(131.13 ± 42.73)ng/mL respectively,and the level on 1,3 d was significantly lower than that on 7 d (P <0.05).Conclusion The relative ad-renocortical insufficiency exists in premature neonates with the early stage of severe infection and is manifested by the decline of plasma cortisol level,which could recover to the normal level on 7 d,but the plasma ACTH level has no relation with infection.

ObjectiveTo investigate the effects of infrared radiation and magnetic fields on the synovitis of rabbit with experimental knee osteoarthritis (OA).MethodsTwenty-four New Zealand grown rabbits were duplicated for OA model of the knee by extended fixation technique, and after 6 weeks, all rabbits were unchained from fixation. The rabbits were randomly divided into four groups: control group (no treatment), infrared group (treated with infrared radiation ), magnet-therapy group (treated with magnetic fields ) and the combined therapy group (treated with infrared radiation and magnetic fields). At the ends of the first, second and third week after treatment, 2 rabbits in each group were taken to measure the general change and histopathology of their synovium.ResultsCompared with other groups, the severity of synovitis (include the synovium line cells proliferation, the invading of granulation and blood vessels in the underlayer of synovium, the infiltration of inflammatory cells) declined significantly in combined therapy group. Scores of Ayral's index of combined group were significantly lower than other groups ( P<0.05), and there was no significant difference between infrared group and magnet-therapy group ( P>0.05).ConclusionThe combination of infrared radiation and magnetic fields can efficiently suppress the synovitis of OA and alleviate the tissue's destructions.

OBJECTIVE:To optimize the extraction process for Sihuang paste.METHODS:The Radix et Rhizoma Rhei,Radix Scutellariae were extracted with ethanol,and the effects of the concentration and dosage of ethanol,and the ext-racting time,extraction times on the content of emodin were investigated by orthogonal experiment.The Rhizoma coptidis and Cortex Phellodendri were extracted by water decoction method,and the effects of amount of water,the soaking time,the decoction time and decoction times on the content of tannin were investigated by orthogonal experiment.RESULTS:The optimum alcohol extracting condition for Radix et Rhizoma Rhei,Radix Scutellaria was as follows:adding 60% alcohol at a dose of 6 times that of the total medicinal substances and extracting for 1 h/time for 3 times.The optimum water extracting condition for Rhizoma Coptidis and Cortex Phellodendri was as follows:soaking medicinal substances in water(with the ratio of medicinal substances to water at 1∶6)for 0.5 h,decocting for 2 h and extracting for 3 times.CONCLUSION:The optimized methods are simple and stable,which provide theoretic basis for industrial production.

Objective To study the vestibular function in patients with sudden deafness .Methods Retrospec-tive analysis of 436 cases of patients with sudden deafness ,being divided into two groups according to whether the merger of vertigo .147 cases with vertigo group ,75 cases of which were mild to moderately severe hearing loss .In-clud the rise type of 28 cases ,26 cases of flat type ,21cases of decline type .72 cases of which were severe hearing loss .In 289 cases without vertigo ,157 cases had mild moderate and severe hearing loss .Includ the rise type of 36 cases ,57 cases of flat type ,64 cases of decline type .One hundred and thirty two cases of which were severe hearing loss .Use video electronystagmogram (VNG) to test the vestibular function .Process the data with SPSS 13 .0 soft-ware .Results One hundred and twenty three(83 .7% )cases of the vertigo group suffered from vestibular function decline ,with 51 cases of mild to moderately severe hearing loss ,72 cases of severe and above .165 (57 .1% )cases of the without vertigo group suffered from vestibular function decline .There were 45 cases of mild to moderately se-vere hearing loss ,120 cases of severe and above .35 patients with vertigo patients with BPPV ,28 cases of which happened within 1 week in sudden deafness occured and 80% of which were vestibular function decline .Conclusion Patients with sudden deafness with vertigo suffered from vestibular function damage .Patients with sudden deafness without vertigo also suffered from vestibular function damage .And the more serious the hearing loss ,the higher the vestibular function decline opportunities .

Objective To detect the argyrophilic proteins in nucleolar organizer regions(Ag-NORs) that express rDNA and rRNA proliferation of T lymphocytes before chemotherapy and after complete remission(CR) in children with primary acute leukemia(AL).Methods The argyrophilic granules area of NOR/nuclear area(I.S%) of T lymphocytes was detected by image analysis system in peripheral blood of 42 patients before chemotherapy and after CR and 30 normal children.Results I.S% in the patients before chemotherapy(5.06%?1.36%) were significantly lower than those in the healthy donors(7.51%?1.06%)(t=8.238 P0.05).Conclusion These results suggest that decrease of Ag-NORs expresses the evidence for tumour induced suppression of immune function of T cells in children with AL prior to treatment.
