Objective To analyze the clinical performance of hepatitis C virus antibody detection by bi-direetional lateral flow method and evaluate whether the bi-directional lateral flow method is suitable for clinical use.Methods Four hurdred and nineteen samples were collected and tested anti-HCV antibodies with hi-directional lateral flow and CMIA kits.These samples contain:107 patients with confirmed hepatitis C virus infection,162 patients with other diseases than hepatitis C virus infection and 150 healthy controls.Two positive reference materials for ELISA were tested at the same time.The testing results were analyzed with statistical methods.Results Compared with RIBA,the sensitivity and specificity of bi- directional lateral flow method were 98.1% and 99.7% respectively,the agreement rate with CMIA was 99.0%.The reproducibility percentage of the+/-20% at the cutoff concentration were 97% and 99% respectively.No crossing reaction with hepatitis A/B/D/E virus infection and HIV-1/2 positive individuals were found in the tests.Conclusion The hi-directional lateral flow method for HCV detection shows good clinical performance and is suitable for clinical use.

Objective To investigate the effect of intrathecal(IT)different concentrations of ozone(O_3) on pain threshold,motor function and cerebral spinal fluid(CSF)malondialdehyde(MDA)concentration and superoxide dismutase(SOD)activity and determine if ozone is toxic to central nervous system(CNS).Methods Thirty New Zealand white rabbits of both sexes aged 3-5 months,weighing 2.5-3.0 kg were randomly divided in 5 groups(n=6 each):groupⅠcontrol;groupⅡpure O_2;groupⅢO_2-O_3 30;groupⅣO_2-O_3 50 and groupⅤO_2-O_3 80.The animals were anesthetized with intraperitoneal pentobarbital.Cerebello-medullary cistern was punctured for IT administration of O_2 and O_3.In groupⅡ2 ml of pure oxygen(O_2)(for medical use)was injected IT.In groupⅢ,ⅣandⅤ2 ml of ozone(O_3)30,50 and 80 mg?L~(-1) was injected IT respectively.Ozone was manufactured by ozone generator(Ozoneline Co,Italy).Before and one day after IT O_3 paw withdrawal latency to heat(PWHL)and to mechanical stimulation(yon Frey filament)(PWML)were measured and motor function was assessed(1=normal,4=severe motor dysfunction and weakness).CSF was obtained at 1,2,4 h after IT O_3 for determination of MDA concentration and SOD activity.Results IT administration of the 3 concentrations of ozone did not affect pain threshold and motor function,but significantly increased SOD activity.MDA concentration decreased significantly at 4 h after IT O_2 or ozone administration in groupⅡ,ⅢandⅣ,but increased significantly at 1 and 2 h after IT ozone in groupⅤ.SOD/MDA was significantly increased at 1,2 and 4h after IT ozone in groupⅢandⅣ,but decreased at 1 and 2 h after IT ozone in groupⅤ.Conclusion IT ozone is toxic to CNS.

To analyze the regularity in combined medication with Xiyanping injection (Xiyanping for short) in the real world by as- sociation rules. Totally 5 822 patients using Xiyanping injection was collected from the 18 Class III Grade I hospitals nationwide to study the combined medication information of the patient with lung infection and make the analysis by using association rules and Apriori. According to the results, major drugs combined with Xiyanping in treatment of lung infection included compound amino acid, inosine, coenzyme A, cytidine triphosphate, vitamin C. Common drugs combined with Xiyanping can be divided into 5 categories: nutrition support therapy (vitamin C, compound amino acid) , coenzymes (coenzyme A, cytidine triphosphate, inosine), expectorants and antiasthmatics (ambroxol, salbutamol, doxofylline), hormones (dexamethasone, budesonide), antibiotics (mainly cefminox). The main combined medicines mostly conformed to the regularity for drugs treating lung infection. In addition, there were two most common medical combination models: the model for Xiyanping combined a single medicine is Xiyanping + nutrition support therapy, while the model for Xiyanping combined two or more than two medicines is Xiyanping + nutrition support therapy + coenzyme. Pharmacologically, Xiyanping is mostly combined with western medicines with similar pharmacological effects to substitute or supplement the antibiotic effect in treating lung infection. However, further studies shall be conducted for the safety and rationality of the combined medication based on clinical practices, in order to provide reference for clinical medication.

OBJECTIVETo evaluate the efficacy and safety of etanercept plus Tripterygium wilfordii polyglycoside (TWP) in elderly patients with active rheumatoid arthritis (RA).

METHODSTotally 46 elderly patients with active RA were randomly assigned to the treatment group (22 cases) and the control group (24 cases). All patients received subcutaneous injection of etanercept, 25 mg each time, twice per week. The dosage was reduced to once per week 3 months later. Patients in the treatment group took TWP Tablet (10 mg each time, three times per day), while those in the control group took methotrexate (MTX), 10 mg each time, once per week. The whole course lasted for 24 weeks. Patients' rest pain, tender joint number, swollen joint number, health assessment questionnaire (HAQ), patients' global assessment, physicians' global assessment, erythrocyte sediment rate (ESR), C reactive protein (CRP), rheumatic factor were assessed at week 0, 4, 8, 12, and 24. The curative effect was statistically evaluated by the United States Institute of Rheumatology ACR20, ACR50, and ACR70 improvement criteria. Meanwhile, any adverse event was recorded and evaluated.

RESULTSTotally 41 completed the trial, and 5 dropped off (3 in the treatment group and 2 in the control group). Compared with the control group, there was no statistical difference in ACR20, ACR50, or ACR70 in the treatment group (P > 0.05). Compared with before treatment in the same group, there was some improvement in tender joint number, swollen joint number, visual analogue scale (VAS) for patients' global assessment, VAS for physicians' global assessment, ESR, CRP, and HAQ between the two groups, showing statistical difference (P < 0.05). Compared with the control group in the same phase, there was no statistical difference in the treatment group (P > 0.05). There was no statistical difference in the occurrence of adverse events between the two groups.

CONCLUSIONSEtanercept plus TWP could achieve equivalent therapeutic effect to that of Etanercept plus MTX. The two regimens could improve clinical signs, symptoms, and QOL related to RA. They were well tolerated in the treatment of elderly patients with active RA.
