The operation is simple,and the fixation is reliable,the function is satisfactory.

Objective To develop a HPLC quantitatively test method of glycyrrhizin, liquiritin and isoliquritigenin simultaneously for licorice. Methods The 67% methanol extracts of licorice powder were analyzed by reverse-phase HPLC on an ODS column, using a gradient elution with a mixture of 1% H3PO4 and acetonitrile. The eluate was monitored by UV absorption at 248, 276, 360 and 370 nm. Results The linear equation of glycyrrhizin was Y =1?106X +16 220, r 2=1. The linear equation of liquiritin was Y= 2?106X+49 444, r 2=0.999 5. The linear equation of isoliquritigenin was Y =1?107X +4.466 7, r 2=1. The recovery rate of glycyrrhizin, liquiritin and isoliquritigenin was 98.01%, 102.63% and 98.18% respectively. Conclusion The method is accurate, stable amd reliable, and can be used to determine the three main chemical contents simultaneously.

OBJECTIVE:To provide the information of drug-use in SARS for reference.METHODS:123medical charts of inpatients from April20,2003to May31,2003were analyzed,including the kinds and the cost of drugs that have been used.The frequency of drug-use and DUI were calculated from DDD of drugs.The kinds and costs of drugs used for930employees were also analyzed.The drug cost per employee was compared with that per inpatient.RESULTS:4kinds of drugs were abused.The dosage and usage of the other drugs were appropriate.17kinds of main drugs and2kinds of decoctions prepared by our hospital have been used to inpatients,which costed559440yuans in all,4548.29yuans per inpatient.While14kinds of drugs and one kind of decoction against SARS were used to employees,which costed about500000yuans in all,537.6yuans per employee.CONCLUSION:SARS is still an unknown disease.Although most of the dosage and usage of drugs were appropriate in prevention and treatment of SARS,whether the drugs should be used or not is open to question.

Objective To understand use of blood pressure-lowering medications and to identify factors contributing to their compliance among hypertensive patients at a community health-care service center under Huairou County Hospital, Beijing to improve community management for hypertensive therapy.Methods Medical records of hypertensive patients who visited Qiaozizhen community health-care service center in Huairou county, Beijing during June 2008 to May 2009 were analyzed and 849 of them were interviewed using a pre-tested, structured questionnaire with most closed ended questions included to understand their use of anti-hypertensive drugs and its related factors. Results In 849 hypertensive patients under community management, 78.92% percent (670/849) took anti-hypertensive drugs, 72.54%percent (486/670) in good compliance with drug treatment, and 29. 63 percent (144/486) under guidance of their general practitioners or visited secondary-care hospitals or above, 62. 14 percent (302/486) took drugs by themselves and 8. 23 percent (40/486) took drugs following advice by their relatives or other hypertensive patients. The most common used drugs in 503 hypertensive patients who could remember names of the drugs included reserpine compound tablets, reserpine and triamterene compound tablets (302/503, 60. 04% ) and calcium-channel blockers ( 181/503,35.98% ). Overall, blood pressure was under control in ( 289/849,34. 04% ) percent of those with community management, and( 189/486, 38. 89% ) percent of them kept in a good compliance, significantly higher than that in those with poor compliance (48/179,26. 82% ) (P =0. 0032). Results of multivariate logistic regression analysis showed that drug compliance associated mainly with complications of hypertension ( OR of 4. 423 and 95% CI of ORs 2. 141 - 9. 137). Conclusions Drug compliance among hypertensive patients is still poor in rural Beijing, most with reserpine compound tablets.It is necessary to pay more attention to health education among hypertensive patients, particularly about when to start drug-taking and how to take drugs in a scientific way-regularly and complying with physicians'prescription.

BACKGROUND: Multiple sclerosis(MS) is a chronic autoimmune disease induced by the interaction between genetic and environmental factors. Its pathogen and the mechanism of the relapse and remission m the course of the disease are still unknown. Most of the MS research centers are looking for the pathogenic polypeptide epitope in proteolipid protein(PLP), myelin sheath basic protein (MBP) and oligodendrocyte glycoprotein (MOG) OBJECTIVE: To compare the proliferation of T cell lines(TCL) in MS induced by myelin sheath and delipidated myelin sheath towards 11 components of myelin sheath to mainly search the possible pathogenic polypeptide epitope in PLP, and investigate the possible effects of abnormal dcgrease in myelin sheath.DESIGN: A case-controlled trial.SETTING: Department of neurology in a hospital of a university.PARTICIPANTS: Mononuclear cells(MNC) of 16 MS cases(clinical relapsing-remitting type, patients did not receive any immunosuppresant for at least 3 months when their peripheral blood samples were taken) and 12 HLA-DR15 healthy volunteers were furnished by Dr. Trotter JL of MS Research Center of Washington University from the cell database.INTERVENTIONS: MS-TCL and normal TCL were induced twice by stimulation with myelin sheath and delipidated myelin sheath in vitro by cell culture in vitro. TCL proliferation was tested by 11 antigens including PLP,MBP, M87-106, P30-49, P40-60, P89-106, P95-117, P117-137,P139-151, P178-191, and P185-206.MAIN OUTCOME MEASURES: Difference of scintillation counting in every minute of every well, and the stimulative index of each well were calculated, and the mean wells with positive proliferation of TCL towards each antigen were confirmed as well.RESULTS: The general specific proliferation towards myelin sheath antigens was bigger in MS group than control group 5.49 ±5.31 to 3.10 ± 3. 17, and delipidated myelin sheath-induced TCL was bigger than myelin sheath-induced one 5. 49 ± 5.31 to 3.41 ± 4. 83 . Delipidated myelin sheath significantly changed the immune responses of MS group,especially the changes of responses towards P30-49, P40-60, P89-106,P117-137, P139-161, and P185-206 were significant compared with that the control group only responded to two polypeptides, which indicated that the antigen epitope of MBP, PLP, M87-106, P95-117, P40-60, and P185-206 might have significance in the triggering of MS autoimmune responses.CONCLUSION: TCL induced by MS myelin sheath has different proliferation towards antigen components of myelin sheath from control group. Delipidated myelin sheath significantly increases TCL proliferation in MS group, which suggests that if MS patients developed abnormal degrease in myelin sheath, TCL would produce autoimmune response towards self-myelin sheath, MBP, PLP and its polypeptide segments all can trigger MS or aggravate the state of the illness. Our finding supports the hypothesis of MS autoimmune pathogenic mechanism.

Eight-weeks old C57BL/6J male mice were treated with normal or high fat diet for4 weeks,and then bone mass,number and activity of osteoclasts,differentiation of osteoblasts from bone marrow mesenchymal cells and the change in lipid genes expression were studied.Compared with the normal diet treated group,bone mass of femur from high fat diet treated animal was decreased,but there were increased number and activity of osteoclasts and raised lipid genes expression levels.Besides,no obvious change was found in differentiation of osteoblasts from bone marrow mesenchymal cells.The loss of bone mass induced with high fat diet in young mice was mainly due to increased activity of osteoclasts and bone resorption.

Department of rheumatology and immunology is a compulsory training department for the standardization training of the residents. However, it has been noted that the residents often ignore the importance of rheumatology. They are usually short of communication skill with the patients and theoretical knowledge. They often have high error rate in the clinical work and training their clini-cal skills and thinking ability is very difficult in the actual work. All of these problems may decrease the training quality and make the training a mere formality. Therefore, in order to carefully implement resident standardization training, a set of specific training programs has been developed, involving in theory of knowledge, practice standardization and comprehensive quality training. With these training programs, the quality and efficiency of the residents' training has greatly improved.
