ObjectiveTo evaluate two "up and down stair" methods used by hemiplegic patients.Methods40 cases with hemiplegia were randomly divided into two groups with 20 cases in each group. Patients in the group A went upstairs with health leg and downstairs with affected leg, while, patients in the group B upstairs with affected leg, downstairs with health leg, and then up and down stairs with health and affected leg alternated. Effects of two training menthods were compared.ResultsEach of two training methods had its advantage and disadvantage, but motor function and mobile ability of patients in the group B were better than patients in the group A (P<0.05).ConclusionHemiplegic patients Should choose different training method of up and down stairs according to his status, and not always choose the method of going upstairs with health leg and downstairs with affected leg.

ObjectiveTo seek the optimal method in treating hemifacial spasm (HFS).MethodThirty HFS patients were selected and randomized into atreatment group and a control group. The treatment group was intervened by selecting cervical Jiaji (EX-B2) points plus conventional acupuncture, while the control group was by conventional acupuncture alone; 15 sessions were regarded as a treatment course, and the therapeutic efficacies were observed and compared after 2 successive treatment courses. ResultThe total effective rate was 86.7% in the treatment group, significantly higher than 66.7% in the control group (P<0.05). ConclusionElectroacupuncture at cervical Jiaji plus conventional acupuncture is significantly effective in treating HFS, and its total effective rate is higher than that of the conventional acupuncture alone.

BACKGROUND:The eradication therapy of glioma is the major problem, and anti-angiogenesis therapy is a potential treatment of glioma.
OBJECTIVE:To confirm the inhibiting effect of endostatin on angiogenesis in vitro, and to lay the foundation in inhibiting the growth of tumor by endostatin in the future.
METHODS:Endostatin mRNA was extracted from the liver of Wistar rats by Trizol and endostatin cDNA was synthesized by RT-PCR. Endostatin cDNA and pcDNA3 were connected and pcDNA3-Endo recombined plasmid was constructed successful y. The recombinant pcDNA3-Endo was transfected into bone marrow mesenchymal stem cells by Lipofectamine. The expression of endostatin was identified by RT-PCR and western blot analysis. Endostatin proteinum activity was detected by ECV-304 cellproliferation inhibition experiment using MTT assay. The in vitro experiments were divided into four groups:recombinant plasmid group, vector plasmid group, liposome control group and blank control group.
RESULTS AND CONCLUSION:PcDNA3-Endo eukaryon expression plasmid was constructed successful y. Endostatin gene can be transcribed and expressed effectively in vitro by pcDNA3-Endo plasmid. The growth of ECV-304 cellwas inhibited obviously by pcDNA3-Endo. The growth of vascular endothelial cells can be inhibited obviously by endostatin gene.

According to the theory of medical ethics,ethical guidelines and moral criterions for medical laboratories are proposed based on the characteristics of the laboratories.Internal management in terms of ethics need to be strengthened,and t the quality of service needs to be improved continually,so as to ensure the rights of patient,protect staffs against professional hazards,and protect the environment.

Objective To make a passive personal sampler for the determination of the styrene in the air. Methods To make a passive personal sampler for the determination of the styrene in the air. Results Under the condition of wind velocity of 100-600 cm/s, relative humidity of 40%-80% and temperature of 10-40 ℃, the sampling flux of the passive sampler was 61.8 ml/min, the capacity was 5.95 mg, the shortest sampling time was 30 min, the self life was at least 30 days, the storage stability was at least 14 days, the RSDs were 8.07%-9.37%. Conclusion This new kind of passive personal sampler can be used as a new device for the determination of the styrene in the air.

Objective:To investigate the consumption situation and cognition of health care products in hospitalized patients, ana-lyze the problems in purchasing and use of health care products to provide evidence for the correct selection and rational use of health care products. Methods:The investigation and analysis was conducted with an anonymous questionnaire on awareness and consumption situation of health care products in hospitalized patients. Results:The survey received 129 valid questionnaires, and more than 1/3 re-spondents did not know the differences between health care products and medicines, and 27. 91％ of them treated diseases with health care products, 57. 36％ of them purchased health care products per month, and 96. 12％ of them thought the efficacy of health care products were inconsistent with the advertising efficacy. Conclusion:Patients cannot distinguish health care products from medicines, and lack of trust in the health care products market. Corresponding measures should be performed to help patients purchase and use of health care products and safeguard their legitimate rights and interests.

Objective: To understand and grasp the current situation and actual demands of China’s pharmaceutical industry, in order to provide a basis for the establishment of the chemometrics guideline in the Chinese Pharmacopoeia.
Methods: Online questionnaire was adopted to investigate the chemometrics backgrounds and demands of pharmaceutical industry practitioners.
Results: The practitioners of China’s pharmaceutical industry had certain expectations and demands for the chemometrics guideline, but the situation of talent reserves was not that optimistic.
Conclusions: It is extremely urgent to develop the chemometrics guideline, as general chapters of the Chinese Pharmacopoeia, which serve as the legal basis to guide the data quality control, the establishment of analytical methods and the verification of analytical methods in analytical practice, so as to ensure the scientific of multivariate analysis methods and reliability of analytical results, and will be conducive to promoting the improvement of China’s pharmaceutical level.

OBJECTIVE:To observe the clinical efficacy of omeprazole plus colloidal bismuth pectin and amoxicillin in the treatment of duodenal ulcer(DU) and on which a cost-effectiveness analysis was performed.METHODS:80 patients with DU were randomly assigned to receive omeprazole+colloidal bismuth pectin+amoxicillin(Group A,n=40) or omeprazole+clar-ithromycin+amoxicillin(Group B,n=40).After the completion of treatment,gastroscopic examination was performed to observe the cure rate of DU and the improvement of clinical symptoms.The cost-effectiveness ratios were compared.RESULTS:In the two groups(A vs.B),the cure rates under gastroscope were 100.00% vs.87.50%(P
