Objective:To establish the quality standard for Sinapis Semen( stir-baked) formula granule. Methods:TLC was used to identify Sinapis Semen; an HPLC method was applied in the content determination of Sinapine thiocyanate in Sinapis Semen ( stir-baked) formula granule with Hibar Purospher STAR C18 (250 mm × 4. 6 mm,5 μm ) column and with the mobile phase consisting of acetonitrile-0. 08 mol·L-1 potassium dihydrogen phosphate (10 ∶90) at the flow rate of 1. 0 ml·min-1 ,the column temperature was 35℃ and the detection wavelength was set at 326 nm. Results:The characteristic spots of Sinapis Semen( stir-baked) formula granule were clearly detected by the established TLC chromatography. Sinapine thiocyanate had a good linear relationship within the concentra-tion range of 0. 012 2-3. 912 3μg(r=0. 999 9). The average recovery was 100. 4% (RSD=0. 6%, n=6).

Objective To explore the difference involved in the activation of inflammation pathway and the plasma level of inflammatory factors in the subjects with different sorts of insulin sensitivity. Methods The study was carried out in 38 women, consisting of obesity (n = 22 ) and control (n = 16 ) groups according to body mass index. The insulin sensitivity was assessed by homeostasis model assessment of insulin resistance (HOMAIR). Plasma concentrations of interleukin-6 (II-6) and IL-1β were determined by enzyme immunoassay. Western blot analysis was used to examine total protein expression and phosphorylation levels of IκB kinase (IKK) ,inhibitor of nuclear factor-κB ( IκB ) in peripheral blood leukcocytes. Electrophoretic mobility shift assay (EMSA)was used to detect the binding activity of NFκB. Results The levels of fasting plasma insulin[62.2 ( 20.0-127. 0) pmol/L vs 19. 15 ( 14. 2-47. 8 ) pmol/L, P<0. 01], HOMA-IR[2. 32 ( 0. 76-5.49 ) vs 0.70(0.53-1.7),P<0.0l], HbA1 C[(5.42±0. 45 ) % vs ( 5.08 ±0. 38) %, P<0. 05], triglyceride[( 1.75 ±0. 68 vs 1.22 ±0. 58 )mmol/L, P<0. 05], plasma IL-6[3. 15 (0. 03-22. 2) pg/ml vs 1.26 (0. 74-6.06 ) pg/ml, P<0. 01], and IL-1 β[6. 53 ( 0. 84-36 ) pg/ml vs 3. 16( 1.48-8. 86 ) pg/ml, P<0. 01]in obesity group were significantly higher than those in control group. Compared with control group, the levels of IKKo, IKKβ expression and IκBα serine phosphorylation in obesity group were markedly increased, while the expression of IκBα was significantly reduced. Accompanied with the degradation of IκBα protein, the binding activity of NFκB in obesity group was significantly increased. Conclusions The plasma levels of IL-6 and IL-1β were significantly raised in obesity group. The activation of IKK-IκB-NFκB pathway is closely associated with the genesis and development of insulin resistance in obese subjects.

ObjectiveTo investigate the effect of intensive dose atorvastatin on preventive contrast-induced nephropathy (CIN) in elder with coronary heart disease (CHD) after elective percutaneous coronary intervention (PCI).Methods110 subjects older than 60 who received elective PCI,were randomly divided into intensive dose atorvastatin group (the study group,n =50) and conventional treatment group (the control group,n =50).On the ba sis of the hydration therapy,the study group received atorvastatin and the control group received atorvastatin.Scr、β2- MG and liver function were checked for evidence of tubular or glomemlar damage before and after elective PCI were compared between the two groups.Ccr was calculated according to Cockcroft-Gault formula;The incidence of the major adverse cardiovascular events (MACE) and cytotoxicity and hepatotoxicity of rosuvastation were respectively recorded in 30 days follow-up period.ResultsCcr in the study group was significantly higher than that in the control group at day 1 [( 73.12 ± 16.89 ) ml/min vs ( 63.89 ± 18.42 ) ml/min,P =0.036],day 2 [( 65.32 ± 13.46 ) ml/min vs (55.63 ± 15.47 )mL/min,P =0.021] ;Blood β2-M in the study group was significantly lower than that in the control group at day 1 [( 2.44 ± 0.42 ) ml/min vs ( 2.69 ± 0.63 ) mL/min,P =0.009],day 3 ( 2.52 ± 0.46 ) mL/min vs (2.81 ±0.63) ml/min,P =0.011],day 3[(2.37 ±0.43) ml/min vs (2.54 ±0.65 ) ml/min,P =0.021].The incidence of CIN was lower in the study group than that in the control group(6％ vs 24％,P =0.012).During 30days clinical follow-up,the incidence of the MACE in the control group was more than the study group ( x2 =5.316,P =0.021).There was no significant difference between the two groups for the cytotoxicity and hepatotoxicity.ConclusionHigh dose atorvastatin may be more efficient in prevention CIN in elder before elective PCI and this higher dose may be safe to the elder.

Objective To evaluate the clinical value of multi-locus polymerase chain reaction (PCR) for identifying Mycobacterium tuberculosis complex isolated in children. Methods The isolates were collected and were first determined by PNB/TCH medium. 7-point PCR sites including 16SrRNA, Rv0577, IS1561, Rv1510, Rv1970, Rv3877/8 and Rv3120, and 4-point PCR sites including ropB, RD1, RD8 (present), RD8 (deleted) were used to amplify them by PCR. Results Total of 204 isolates were collected, in which 199 were Mycobacterium tuberculosis, 3 were Mycobacterium bovis, and 2 were non-tuberculous mycobacteria by the PNB/TCH method. 4-point PCR analysis showed that 196 were Mycobacterium tuberculosis, 2 were Mycobacterium bovis, 3 were BCG species and 3 were non-tuberculous mycobacteria. 7-point PCR analysis showed that 191 were Mycobacterium tuberculosis, 2 were Mycobacterium bovis, 3 were BCG species, 4 were African Mycobacterium type I, 1 was Mycobacterium caprae, 1 was Mycobacterium microti and 2 were non-tuberculous mycobacteria. Conclusion Compared with the conventional method, the PCR identification in 4-point PCR method and 7-point PCR method could rapidly identify the BCG among the complex group in children tuberculosis. 7-point PCR method was able to identify all the subspecies of Mycobacterium, except Africa Mycobacterium. 4-point PCR method would be more rapid and easier in the identification of BCG strains.

Objective To develop a microsphere-based suspension array for simultaneous detec-tion and identification of Salmonella H antigens by using Luminex xTAG technology and to evaluate its capa-bility in serotyping Salmonella strains. Methods The fliC and fljB genes, encoding the H antigen of Salmo-nella, were selected as the target genes. Universal upstream primers were designed based on the highly con-served regions of fliC and fljB genes, and the corresponding specific reverse primers were designed based on the variable regions. While synthesizing, the 5′end of each upstream primer was labeled with biotin and the 5′end of each specific reverse primer was modified with its certain TAG sequence. After amplified and la-beled with biotin and TAG sequence, the PCR products of specimens were hybridized with the mixture of va-rious MagPlex-xTAGTM microspheres. Each set of microspheres contained its unique anti-TAG sequences. The results of hybridization were analyzed by using Luminex MagPix reader system and the median fluores-cence intensity ( MFI) was reported. The H antigens of 145 Salmonella strains were identified with this de-veloped xTAG suspension array, and the results were compared with those obtained by using traditional ser-um agglutination test. Results The PCR products of different H antigens ranged from 94 bp to 245 bp and could be identified by hybridizing with MagPlex-xTAGTM microspheres. There was no cross-reaction between different H antigens or with DNAs derived from Escherichia coli, Vibrio cholerae, Vibrio parahaemolyticus and Shigella flexneri. Compared with the traditional serum agglutination test, the sensitivity and specificity of the xTAG suspension array in the identification of H antigens of 145 Salmonella strains were 95. 1% and 100%, respectively. Conclusion The developed xTAG suspension array was a specific, accurate and effective method for simultaneous detection and identification of 31 H antigens of common Salmonella serovars strains. It could be used for determining the H antigens of more than 90 Salmonella strains within 5 hours.
