To study the chemical constituents from Zanthoxylum simulans and their anti-inflammatory activity. The constituents of Z. simulans were isolated and purified using various column chromatographies. Their chemical structures were elucidated using extensive spectroscopic methods. The compounds were assayed inhibitory activity against NO production in LPS stimulated RAW 264.7 cells. Four compounds were obtained from the ethanol extract of Z. simulans and determined to be isozanthpodocarpin B(1), kobusin (2), (+)-fargesin (3), and epieudesmin (4). Compound 1 exhibited NO production inhibitory effect with IC50 value of 14.49 µmol · L(-1). Compound 1 is a new dimeric lignan and may be serve as potential anti-inflammatory agent in the future.

Objective To establish a convenient, fast, economic and hypersensitive low-density DNA array method to detect the genotypes of human papillomavirus (HPV) and evaluate its application in clinic services.Methods HPV in cervical swab samples from 355 suspected female patients collected in gynaecology and obstetrics clinic were genotyped by hybrid capture (HC) II method and low-density DNA array simultaneously. HPV in 730 clinic samples from the area of Pearl River delta were genotyped by low-density DNA array.Results Among 355 suspected samples positive HPV-DNA were detectable in 211 (59.4%) samples by DNA array and 222 (62.5%) samples by HCII method. The concordance rate between the two assays was 94.1%. In the HPV genotypes 15 high-risk type and 5 low-risk type were detected by low-density DNA array. The most common high-risk types were HPV-16, 52, 58 and 56. The peak age of HPV infection was 26-30 years. The distribution of genotypes was different from various degree of cervical changes.Conclusion Either single type or multiple type of HPV infection can be detected by low-density DNA array. The combination of HPV detection with cytology detection will provide instruction for cervical cancer screening.

To analyze and compare the protective effects of active components in different ethyl acetate extracts (EAEEPs) from Eclipta prostrate, in order to study the comparison of materials bases protecting normal human bronchial epithelial (NHBE) cells. The MTT assay was taken to compare the protective effect of different EAEEPs on cigarette smoke extracts (CSE) -induced NHBE cells. The ultra-performance liquid chromatography (UPLC) was applied to analyze the content of phenolic acid, coumaric grass ether and flavonoid in EAEEPs. According to the results, all of the eight EAEEPs (0-200 mg x L(-1)) showed certain protective effect on NHBE cells, with statistical difference. Specifically, the total mass of EAEEP VII (89.15 mg x L(-1)) and EAEEP VIII (57.44 mg x L(-1)), which showed the strongest activity, was not the highest, while EAEEP III (132.25 mg x L(-1)) displayed the highest total mass. In the combination with the "component structure" theory, the analysis showed a significant difference in the mass structure among phenolic acid, coumaric grass ether and flavonoid in EAEEP VIII and EAEEP VIII, which were 1.0: 1. 0: 0.5 and 1.0: 1.9: 0.8, respectively. The results suggested a specific optimal "component structure" relationship may exist in EAEEP, which could provide reference for the material base study and quality control.

Objective To assess and compare the effectiveness of gadolinium diethylenetriamine pentacetic acid(Gd-DTPA) solution and barium sulfate(BaSO4) suspension with different concentrations in improving the imaging quality of magnetic resonance cholangiopancreatography(MRCP). Methods The phantom study was carried out to determine the optimal concentration of Gd-DTPA and BaSO4 suspension used as an oral negative contrast agent in MRCP.The patients were grouped randomly and performed MRCP before and after using oral contrast agents in combination with intravenous injection of contrast agents.A comparison of the influence of BaSO4 suspension and Gd-DTPA with different concentrations on the signal intensity of the fluid in gastrointestinal tract on MRCP images was made.Results The phantom study showed that the dilution ratio 1∶10 of Gd-DTPA solution and 100%(W/V)BaSO4 suspension were the optimal concentrations in decreasing the signal intensity.In all patients the high signal intensity of the gastrointestinal fluid was completely suppressed after oral administration of Gd-DTPA diluted solution(P

Objective Through analyzing the epidemic characteristics and laws of human brucellosis in Gansu province during the past two years,to provide the basis for control of the disease. Methods Using China Information System for Diseases Control and Prevention V2.0 and survey data of human brucellosis outbreak,we calculated the incidence of brucellosis and the composition of new cases and chronic cases in 2009 and 2010, respectively, and analyzed the three distributions of the disease. Results Brucellosis incidence was 0.37 per million in 2009, and 1.7 per million in 2010. The new cases accounted for 54.6％(83/152) and 51.8％(43/83),and chronic cases were 53.3％ (81/152) and 56.6％ (47/83), respectively. About 1/3 of the counties (cities,districts) was found to be with the disease, and most cases were clustered in Hexi Corridor and Longdong area of Gansu province. There were three counties with outbreak. Time distribution of the disease was jagged. May, July,September and December were high, with September the highest. Sex ratio was 3 : 1, and mean age was 46 years old.67.7％ (159/235) of cases were farmers, followed by retired officers and herders, with a percentage of about 7％,respectively. Conclusions Epidemic of human brucellosis shows a rapidly rising trend in Gansu province. There are new patients throughout the year, and young farmers are the main victims. A high proportion of chronic brucellosis is more harmful. Strengthen the prevention and control of the disease to increase their brucellosis protective awareness.

Objective To assess the predictive value of thiopurine methyltransferase genotyping and enzyme activity in relation to side effects in patients with inflammatory bowel disease (IBD) who were treated with azathioprine (AZA). Methods One hundred and eleven IBD patients (26 with ulcerative colitis and 86 with Cronh's disease) with indication of AZA administration between April 2004 and Dec. 2009 were enrolled. All patients received 2 mg/kg of AZA daily. Polymerase chain reaction and high performance liquid chromatography were used to genotype the TPMT * 2, * 3A, * 3B, * 3C and to detect TPMT activity, respectively. The association of TPMT genotype and activity with side effects was analyzed in patients treated with AZA for 24 weeks or more, or in those discontinued AZA because of adverse effects. Results Adverse effects were reported in 38(33. 9%) patients, the most frequent being myelosuppression (20. 5%). The frequency of TPMT * 3C heterozygous mutation was 0. 9% (1/112). The TPMT activity was (12. 9±4. 8) U/ml RBC with unimodal distribution. One patient with TPMT * 3C heterozygous mutation developed myelosuppression at the 4th week after AZA treatment. The TPMP genotype myelosuppression patients. Conclusions TPMT genotype mutation and low enzyme activity can be used to predict myelosuppression with high specifically and low sensitivity. In patients treated with AZA, co-administration of 5-ASA results in a high frequency of myelosuppression with no effect on TPMT activity.

Most Chinese medicine has good clinical efficacy and application. However, the material basis is vague for the lack of basic research, the value of Chinese medicine is hard to reflect for the low technology level and product quality is difficult to maintain for the quality control indicator selection is incorrect. Chinese medicine Jinfukang oral liquid is a typical product of Chinese medicines. Jinfukang oral liquid was selected as a model drug in this article. Based on the overall concept and systems theory of traditional Chinese medicine, the research idea and technology system for modern Chinese medicine secondary exploitation was formed. The system includes three parts, for the first, basic research to make clear the components structure and their action mechanism, for the second, technology upgraded to optimize process and improve the product quality, for the last, exploring the associated industry to form the industrial chain. The research ideas and technology system based on the material basis research and development of modern Chinese medicine, guided with component structure in Chinese medicine and aimed clinical needs. This research ideas and technology system provides strategies and methods for the development of modern Chinese medicine secondary exploitation.
