OBJECTIVE:To provide reference for implementing relevant policies and measures,and promote rational drug use. METHODS:The cognition(questionnaire)and application(prescription spot checks)about antibiotics and glucocorticoids by 191 rural doctors from 14 township hospitals and 18 health room in area A,B and C(representing the economically developed areas, moderately developed areas and undeveloped areas)were investigated,and the results were statistically analyzed. RESULTS:Total-ly 382 questionnaires were sent out(191 for antibiotics and 191 for glucocorticoids),and 382 were effectively received with effec-tive recovery of 100%;and 2 300 prescriptions were checked. Results of questionnaire showed,there were still some misunder-standings and blindness among the rural doctors'cognition and application about antibiotics and glucocorticoids,the usage of β-lac-tam was not fully grasped,part of the empirical use of antibiotics and drug treatment was still not entirely clear,more than 40%had no clear ideas about the classification and contraindications of hormones,and more than half of them didn't know the Glucocor-ticoids Clinical Practice Guidelines;results of prescription spot checks showed,there were regional differences about the proportion of antibiotics and glucocorticoids,area A had the highest proportion among 3 areas,accounting for 60.9% and 18.9%,respective-ly. And area C showed highest proportion about unreasonable prescriptions,accounting for 22.5%. CONCLUSIONS:The cognition and reasonable use of rural doctors for antibiotics and glucocorticoids still needs to be strengthened. It is suggested to take effective measures,formulate and implement the corresponding supervision system,strengthen antibiotics and glucocorticoids knowledge training for rural doctors and fully implement the the principles of rational drug use to improve the rational drug use.

OBJECTIVE To investigate the distribution and antibiotic resistance of nonfermenting gram-negative bacilli isolated from lower respiratory tract infection patients from 2003 to 2007 for rational antimicrobial therapy in practice.METHODS The data of distribution and antibiotic resistance of nonfermenting gram-negative bacilli isolated from sputum samples of lower respiratory tract infection in our hospital from 2003 to 2007 were retrospectively analysed.RESULTS The most predominant nonfermenting gram-negative bacilli isolates were Pseudomonas aeruginosa,Acinetobacter baumannii,Acinetobacter lwoffii and Stenotrophomonas maltophilia.From 2003 to 2007,the resistance rates of these isolates to 15 antibiotics increased,especially P.aeruginosa to ceftazidime.The resistance changed from 30.2% in 2003 to 55.4% in 2005,54.8% in 2006,and reduced to 41.5% in 2007.The resistance to gentamicin,imipenem,netilmicin,ticarcillin and tobramycin varied in the similar way.The resistance of A.baumannii to imipenem increased from 21.1% to 59.7% within the five years.The resistance rate of A.lwoffi was still relatively low.S.maltophilis isolates were highly multi-resistant to antimicrobial agents tested with a rate ranging from 61.9%-100.0% except ceftazidime,ticarcillin and trimethoprim-sulfamethoxazole.CONCLUSIONS P.aeruginosa,A.baumanii and S.maltophilia are the main nonfermentive pathogens of lower respiratory tract infections and not susceptive to many antibiotics.The tendency of susceptibility and distribution changes of those bacteria should be considered in practice for proper antimicrobial therapy.

Objective To assess the clinical significance of serum high sensitive C-reactive protein (hs-CRP) in patients undergone prostate biopsy.Methods A total of 273 consecutive patients were enrolled,aged 44-95 years (mean,69 years).All the patients underwent prostate biopsy.The pathological findings showed 96 cases with prostate cancer (PCa) and 177 cases with benign prostate hyperplasia (BPH).The difference of hs-CRP level between patients with PCa and those with BPH was analyzed.The positive prostate biopsy rate was compared between the patients with high hs-CRP level and those with normal hs-CRP level.Logistic regression was used to evaluate the effect of factors such as hs-CRP,tPSA,PSA density,prostate volume and age on prostate biopsy.Results The medians (interquartile range) of hs-CRP were 3.22 mg/L (1.22-9.84 mg/L) in patients with PCa and 1.24 mg/L (0.55-2.76 mg/L) in those with BPH,respectively,with significant difference(P＜0.05).The positive prostate biopsy rate in patients with high hs-CRP (＞ 3 mg/L)was 55％ (51/92),higher than that in those with normal hs-CRP (≤ 3 mg/L).The odds ratio of hs-CRP was larger than that of all other factors analyzed including tPSA,prostate volume and age according to the Logistic regression analysis.Conclusions Elevated serum hs-CRP level is associated with increased positive prostate biopsy.Serum hs-CRP acts as an independent factor increasing the positive prostate biopsy rate in patients undergone prostate biopsy.

BACKGROUND:In spectral CT imaging study, the selection of scanning parameters is considered by most researchers, but the effects of measuring position are often overlooked. Actual measurement found that different measurement location had significant impact on the result of the measurement. Through measurement and mathematical model of a large amount of data, we can correct the measurement results of different location. The results with real data alignment are higher. OBJECTIVE:To explore effects of different measuring positions on results in spectral CT imaging, and to optimize correction coefficients. METHODS:GE standard water phantom was applied to orderly obtain 5 combined scanning parameters with 552 groups of data. Size measurement method was divided into two measuring range:ROI1 and ROI2. We selected 10 points to measure CT value, including Center, North, South, West and East. The measurement data of ROI1 and ROI2 were classified and screened based on the same sequence. Mathematical modeling and probability statistics analysis were used to optimize correction coefficient, get calibration function and draw experimental simulation curve. RESULTS AND CONCLUSION:(1) Measuring methods of ROI1 were superior to the ROI2’s on water phantom in spectrum CT. (2) To different scanning sequences, the measuring results were different. To the same scanning sequences, the measurements for different positions on water phantom in spectrum CT had remarkable influence on the measuring results, which varied from points to points. (3) Through setting up mathematical modeling, using method of statistical analysis, we could get the correction function on different measuring positions. (4) Above results confirmed that compared with the theoretical model and the experimental data of spectral CT scanning parameters, the coefficients of position can be adjusted, which can optimize the measuring results.
