OBJECTIVE To investigate the application of antibacterials in patients accepted operation in grass-roots(hospitals),so to standardize the application of antibacterials and cut down the medical cost.METHODS Full-time administrators for nosocomial infection investigated the application of antibacterials in patients who accepted(operation) in Sep 2004,and filled in the questionnaires.RESULTS In 1 383 cases of 11 hospitals the application rate of antibacterials was 98.63%;in which 86.50% were for prophylactic usage and 13.50% for therapeutic usage;(29.90%) for single antibiotics treatment and 50.15% for bigeminy,18.70% were for trigeminy.Time of(application) differentiated(6.90,7.00,6.60d) fromⅠto Ⅲ kinds of operation.Per capita cost of antibacterials was $956.50(47.60%).CONCLUSIONS High cost of antibacterials results from such factors as multiple kinds,long time and(combined) application.

Objective To analysis of the thyroid hormone test results of Abbott Architect ci16200 automatic biochemical-im-mune analyzer (Abbott system) and Roche Cobas e601 automated immunoassay analyzer (Roche system) .Methods The thyroid hormone(including T4 ,FT4 ,T3 ,FT3 ,TSH ) levels of 93 cases of serum samples were respectively detected by Abbott system (CMIA) and Roche system (ECLIA) ,and the results were analyzed .Results The thyroid hormone test results of the two systems had a good correlation ,and the coefficients of T4 ,FT4 ,T3 ,FT3 ,and TSH were 0 .960 ,0 .962 ,0 .976 ,0 .900 ,and 0 .999(P<0 .01) . However ,there were significant difference of the detection results of the two systems(P<0 .05) .Conclusion The thyroid hormone test results of Abbott system and Roche system are not comparable .

In the magnetic induction tomography(MIT) system,the electrical conductivity of biological tissue is direct proportion to the phase difference between the excitation signal and the detection signal.To obtain the image of the contribution of tissue's electrical conductivity,the system must have the function of phase detection with high accuracy.The paper focuses on the means of digital phase detection,including FFT method,the correlation method and the classic method,which are ultimately compared with analogue phase detection method.The experimental results show that FFT method and the correlation method,with low error level and high linearity,can better detect the phase difference with the level of 0.1?.The digital phase difference detection provides a kind of effective method for MIT system.

ABSTRACT:Objective To a rare case of double primary cancer (hepatocellular carcinoma with gallbladder)to guide clinical application.Methods and Results We reported one case of primary hepatocellular carcinoma and gallbladder.A male patient,54 years old,had main complaints of intermittent right upper quadrant pain for 4 days. The abdominal CT of the local county hospital showed gallstones,gallbladder with liver infiltration.And then he went to the First Affiliated Hospital of Xi’an Jiaotong University for further treatment.Laboratory examination revealed:HBsAg(+),HBcAb(+),alpha-fetoprotein (AFP)> 60 500 ng/mL,carcinoembryonic antigen (CEA) 5.25 ng/mL.Abdominal CT showed hilar slightly stronger light echo groups:liver cancer or gallbladder cancer? Hepatic artery and portal vein CT imaging (CTA+CTV)examination showed the malignant tumor shadow in the inside of the left hepatic lobe huge,uneven thickening of the gallbladder wall,suspected liver disease with gallbladder infringement or gallbladder disease with liver infringement. With the preoperative preliminary consideration of primary liver cancer with infiltration of the gallbladder,we chose the operation as the resection of segment Ⅳ b and Ⅴ of the liver,cholecystectomy and T tube drainage.Pathological examination postoperative showed the bulky liver carcinoma grade Ⅲ and the poorly differentiated adenocarcinoma of gallbladder.A month later,abdominal CT showed the tumor spread intrahepatic,prompting the poor prognosis.Conclusion The two which are not continuous,which is the standard of double primary cancer,are not suitable for all double primary cancers.This case provides useful experience for future similar diagnosis and treatment of disease,and also helps us with timely and accurate identification of “metastatic”or “primary”,which is the key point for clinicians to give patients an effective treatment.

OBJECTIVE:To investigate the preparation technic and method of quality control of Xinyoukexing tincture(XYKX) METHODS:To determine the content of Valaciclovir by spectrophotography,and podophyllotoxin by dual-wavelength spectrophotography RESULTS:In the range of 14 88～34 72?g/ml,the Valaciclovir concentration in XYKX was in direct proportion to the absorption at 310 4nm,C=44 5 905A+1 7 556,r=0 9 998 In the range of 17 50～50 12?g/ml,the podophyllotoxin concentration in XYKX was in direct proportion to the absorption at 292nm,C=97 7 981Ap292+1 3 614,r=0 9 999,AP292=As292-As325 CONCLUSION:The preparation technic of XYKX is simple and the method of quality control is feasible
