Objective To genotype Yersinia pestis and explore intrinsic relationship among different ecotypes of Yersinia pestis in Yunnan foci.Methods A total of 171 strains from three types of Yersinia pestis,house mouse,wild-type mouse and Yulong Yersinia pestis,were tested.Twenty-three different regions (DFR) were used to genotype and cluster analysis was performed using BioNumerics 5.0.Results A total of 171 Yersinia pestis were divided into 7 genotypes by 23 DFRs,which were Genomovar5,Genomovar7,Genomovar9 and 4 newly discovered genotypes.The genotypes of all Yulong plague were Genomovar5.The genotypes of the 16 strains of wild-type mouse plague (the highland of northwestern Yunnan Province type) were divided to 3 genotypes,13 of them were Genomovar 7,2 of them were Genomovar9,and 1 of them was newly discovered genotype Genomovaryn1.The genotypes of the 148 strains of house mouse plague(the residential area of Yunnan and Fujian Provinces type) were divided into 4 genotypes,145 of them were Genomovar9,and 3 of them were newly discovered including Genomovar-yn2,-yn3 and-yn4.The ecological typing results of clustering showed genotype of Yulong plague was similar to the highland of northwestern Yunnan Province type(wild-type mouse plague),and the percentage of similarity was up to 87.20％,but only up to 73.75％ to the residential area of Yunnan and Fujian Provinces type (house mouse plague).The genotypes of 2 wild-type strains of the highland of northwestern Yunnan Province type(wild-type mouse) and main genotypes of the residential area of Yunnan and Fujian Provinces type(house mouse)were Genomovar 9.The genotype of Genomovar-yn 1 of the highland of northwestern Yunnan Province type was similar to Genomovar 7,but lack of DFR 11.The genotypes of Genomovar-yn2,-yn3 and-yn4 of the residential area of Yunnan and Fujian Provinces type were similar to Genomovar 9,but lack of DFR 10,DFR 9 and DFR 11,respectively.Conclusions One newly genotype strain is found in wild-type mouse plague and 3 newly genotype strains are founded in house mouse plague.Wild-type mouse strains are founded in the house mouse strains.The similarity of genotype between Yulong plague and the highland of northwestern Yunnan Province type (wild-type mouse plague) is high while the similarity between Yulong plague and the residential area of Yunnan and Fujian Provinces type(house mouse plague) is low.

OBJECTIVETo evaluate the outcomes of T3a prostate cancer with unfavorable prognostic factors treated with permanent interstitial brachytherapy combined with external radiotherapy and hormone therapy.

METHODSFrom January 2003 to December 2008, 38 patients classified as T3a prostate cancer with unfavorable prognostic factors were treated with trimodality therapy (brachytherapy + external radiotherapy + hormone therapy). The prescription dose of brachytherapy and external radiotherapy were 110 Gy and 45 Gy, respectively. The duration of hormone therapy was 2-3 years. The endpoints of this study included biochemical failure-free survival (BFFS), distant metastasis-free survival (DMFS), cancer-specific survival (CSS), and overall survival (OS). Survival curves were calculated using the Kaplan-Meier method. The Log-rank test was used to identify the prognostic predictors for univariate analysis.

RESULTSThe median follow-up was 71 months. The serum pre-treatment prostate-specific antigen (PSA) level ranged from 10.0 to 99.8 ng/ml (mean 56.3 ng/ml), the Gleason score ranged from 5 to 9 (median 8), and the percentage of positive biopsy cores ranged from 10% to 100% (mean 65%). The 5-year BFFS, DMFS, CSS, and OS rates were 44%, 69%, 82%, and 76%, respectively. All biochemical failures occurred within 40 months. The percentage of positive biopsy cores was significantly correlated with BFFS, DMFS, and OS (all P=0.000), and the Gleason score with DMFS (P=0.000) and OS (P=0.001).

CONCLUSIONST3a prostate cancer with unfavorable prognostic factors presents not so optimistic outcome. Hormone therapy should be applied to prolong the biochemical progression-free or metastasis-free survival. The percentage of positive biopsy cores and the Gleason score are significant prognostic factors.

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.

This study is to establish physiologically based pharmacokinetic (PBPK) models of famitinib in rat and monkey, and then to predict the pharmacokinetics and tissue distribution of famitinib in human based on the PBPK models. According to published paper, previous studies and the chemical properties of famitinib predicted by ACD/ADME suite and SimCYP, the PBPK models of rat and monkey were established and optimized using GastroPlus. And then, the PBPK models were applied to predict the pharmacokinetic and tissue distribution of famitinib in human. The results showed that the PBPK models of rat and monkey can fit the observed data well, and the AUC0-∞, ratios of observed and calculated data in rat and monkey were 1.00 and 0.97, respectively. The AUC0-∞, ratios of observed and predicted data in human were 1.63 (rat to human) and 1.57 (monkey to human), respectively. The rat and monkey PBPK models of famitinib were well established, and the PBPK models were applied in predicting pharmacokinetic of famitinib in human successfully. Hence, the PBPK model of famitinib in human could be applied in future drug-drug interaction study.
