Objective:To establish the drug release determination conditions and method for methylphenidate hydrochloride bipolar controlled release osmotic pump tablets. Methods: The drug release of the tablets was determined by HPLC using a Diamonsil C18 (250 mm × 4. 6 mm, 5 μm) column with acetonitrile-KH2 PO4 (0. 02 mol·L-1 ,and pH was adjusted to 3. 0 by 1% H3 PO4 solution) (30∶ 70) as the mobile phase at a flow rate of 1 ml·min-1 , the column temperature was 35 ℃ and the injection volume was 20 μl. The effects of release medium, release apparatus and rotation speed on the release of methylphenidate hydrochloride bipolar controlled release osmotic pump tablets were studied as well. Results:The established drug release determination method had a good linear rela-tionship within the range of 1. 0-24. 0 μg·ml-1(r=0. 999 5), and the average recovery was 100. 5%(RSD=1. 58%, n = 6). Un-der the conditions of 900 ml pH 3. 0 phosphate buffer solution as the release medium and the rotation speed of 50 r·min-1 , the drug was quickly released in 0-2h, and then the release behavior was complied with a zero-level model in vitro in 2-10h with the release e-quation of Q=5. 505t+44. 221(r=0. 994 5). Conclusion:The method is simple, accurate and reliable, and suitable for the quality control of methylphenidate hydrochloride bipolar controlled release osmotic pump tablets.

By taking the course of laboratory hematology in Curtin University in Australia as an ex-ample, this paper introduced the characteristics of its teaching mode, teaching contents, teaching methods, assessment methods and laboratory practice. The advantages and disadvantages of education characteristics between Australia and China were compared and analyzed on the training methods and the training objec-tives, respectively. The education characteristics of laboratory hematology in Curtin University provided an important inspiration for our education reform in the field of medical laboratory in the future.

OBJECTIVE:To investigate the satisfaction degree of outpatients on policy of separation of clinical pharmacy from 4 third grade hospitals in Shanghai,and provide reference for promoting medical reform policy. METHODS:Parts of outpatients in the 4 new suburb third grade hospitals were investigated by the questionnaire and interview in Shanghai city,and the data was sta-tistically analyzed by Excel software and SPSS 19.0 software. RESULTS:Totally 400 questionnaires were sent out and 368 were valid with effective recovery of 94.3%. The awareness rate of medical separation policy was 81.3% in the outpatients;55.5% of outpatients thought that medicine cost savings effect was not obvious;the overall satisfaction of patients was 91.6%,and the high-est of satisfaction was the service attitude and the lowest was medical expenses. CONCLUSIONS:Policy of separation of clinical pharmacy has reduced the medical expenses,guided the triage treatment of patients partly and improved the satisfaction of patients. It is suggested to shorten the waiting time by optimizing examination process,strengthen price regulation in drug,standardize pro-duction and distribution process,improve use rate of essential medicines and promote clinical rational drug use for further improve-ment of satisfaction.

Objective To observe the effect of Zhuyun Capsule(Pregnant-promoting Capsule)on serum sex hormone and expres- sion of ovarian cytokine of polycystic ovary syndrome(PCOS)rats.Methods Progestogen plus human chorionic gonadotrophin (HCG)was adopted to make PCOS rat models.Totally 40 SD rats were randomized into control group,PCOS model group,Zhuyun Capsule group,and clomiphene citrate group with 10 in each.Radioimmune assay(RIA)was used to measure the sex hormone and immunohistochemical test was done to measure the expression of tumor necrosis factor-?(TNF-?)of ovarian tissue,insulin-like growth factors-1(IGF-1),and leukemia inhibitory factor(LIF)to analyze the relations among these factors.Results Zhuyun Capsule could reduce greatly serum testosterone(T)and luteinizing hormone(LH),decrease expression of TNF-?and IGF-1,but increase expres- sion of LIF.Conclusion Zhuyun Capsule could regulate endocrine function and expression of ovarian cytokine to improve gonad func- tions of PCOS rats and to promote the maturation of follicle and ovulation.

OBJECTIVETo investigate the relationship between hormone sensitive lipase (HSL) gene polymorphism and aerobic endurance.

METHODSThe (CA)n repeats polymorphism genotypes in HSL intro 6 of 123 outstanding long distance runners and 127 controls of Han nationality in northern China were analyzed by PCR and Fluorescence labeled STR-genescan. Repeat polymorphisms were grouped according to segmentation point and alleles were divided into long or short chains. Chi-square test was used to analyze the frequency difference of allelic and genotypic between athlete and control groups.

RESULTS(CA) n repeats polymorphism in HSL gene was total of 9 different repeat number of alleles, which composed of 25 different genotypes. The chi-square test result showed that when compared short and long chain alleles split by 4, there was a significant difference (P <0.05) of genotype distribution in 5/10 km group compared with control. Compared the rest groups with control, there was no significant difference.

CONCLUSIONCompared short and long chain alleles split by 4, the LL genotype of (CA)n of HSL was associated with aerobic endurance and it might be a molecular marker of elite 5/10 km long distance runners.

Objective:To prepare the production of TIGIT-Fc fusion protein using H22 cells stably integrated the gene by lentivirus vector , and to explore the immunoregulatory effect on macrophages by TIGIT-Fc.Methods: TIGIT-Fc fusion gene were constructed by molecular cloning.The fusion gene was then subcloned to plasmids contained the secretion signaling peptide .The secrected TIGIT-Fc fusion gene was inserted into the lentivirus backbone vector.The purified lentivirus vector was the used to infect the murine H22 cell line.TIGIT-Fc protein was purified by protein A column from the ascites of H 22-injected C57BL/6 mice.Macrophages stimulated by lipopolysaccharide ( LPS ) was challenged to TIGIT-Fc treatment or control.Cytokine levels was then detected by ELISA.Results: TIGIT-Fc protein was purified from the ascites of H 22-injected mice.PVR was upregulated in LPS-treated macrophages.IL-10 level was upregulated in TIGIT-Fc treated macrophages.Conclusion: TIGIT-Fc promotes the mature macrophages to secrete anti-inflammatory cytokine IL-10.

Bacillus cereus B-04 antagonist to Botrytis cinerea were isolated from samples of tomato soil infected by Botrytis cinerea in Zibo, which are identified through a series of morphological and biochemical characteristics and the sequence of 16SrDNA. Aiming at enhancing the inhibitory effect of this strain, a 4.1kb DNA fragment containing ?-1,3-glucanases gene from pUC1940 was inserted into vector pBE2 and pHY300PLK to construct recombination plasmids, PBE2-glu and pHY300PLK-glu, which were transferred into Bacillus cereus B-04, resulting in a new strain named B-04-glu. Restriction enzyme digestion and ?-1,3-glucanases plate culture confirmed that B-04-glu contained a functional ?-1,3-glucanases gene. Compared to the wild strain B-04, B-04-glu had an increased inhibitory effect against Botrytis cinerea on tomato.

Objective: To investigate the effects of Rehannia glutinosa decoction (RGD)、 Rehmannia glutinosa polysaccharide (RGP) and Rehmannia glutinosa non polysaccharide (RGNP) on peripheral hemogram in mice. Methods: The first experimental group were continuously given RGD、RGP and RGNP for nine days, and then blood sample was taken from tails for determination of peripheral hemogram. The second group were given RGD、RGP and RGNP for five days, after making the blood difficiency model of cyclophosphamide. Determinating peripheral hemogram of the third group, after that those mice were given cyclophosphamide by 2 days, 4 days, 6 days, 8 days. Results: Peripheral hemogram of the every normal group has no difference. To compare the model of blood difficiency group and the control group, there were significant differences, RGNP can only enhance WBC. Both RGP and RGNP can reduce WBC of the mice model of anti cyclophosphamide, while RGP was superior to RGNP. Conclusion: Rehmannia glutinosa has dual directional adjustment function. RGP is tonifying blood active fraction of RG.
