Objective To investigate the clinical value of the combined detection of Golgi protein 73 (GP73),alpha-fetoprotein variant-L3 (AFP-L3)and transforming growth factorβ1(TGFβ1)in the early diagnosis of hepatocellular carcinoma (HCC).Meth-ods 48 cases of healthy control,42 cases of hepatitis B,50 cases of posthepatitic cirrhosis and 58 cases of HCC were selected and detected GP73,AFP-L3 and TGFβ1.The detection results were compared among 4 groups.Results (1)The levels of GP73,AFP-L3 and TGFβ1 had statistical differences among 4 groups(P <0.05 );(2 )The positive rate of the 3-marker combined detection reached 96.55%,which was higher than that of the 2-marker combined detection and the single marker detection.Conclusion (1) GP73,AFP-L3 and TGFβ1 may be used as the serum indicators for the early diagnosis of HCC;(2)Compared with the traditional HCC marker AFP,AFP-L3 has relatively high sensitivity and specificity and has the important role in the differential diagnosis of benign and malignant diseases of the liver,which is considered as a better serum marker in the HCC diagnosis;(3)The 3-indicator combined detection can significantly improve the positive detection rate of HCC and has better application value.

OBJECTIVE To study the distribution and drug resistance of pathogens in urinary system,provide the credible evidence with the clinic diagnosis and the treatment of urinary diseases,and give doctors reasonable advice for medicine usage. METHODS The pathogens from the urine specimens were isolated and cultured from the patients in hospital from Jan 2003 to Dec 2004.The total 536 strains of pathogens were identified and the drug resistance was analyzed. RESULTS Escherichia coli among the pathogens infected the urinary system rated the top(57.0%),secondly were Enterococcus,Klebsiella,Staphylococcus,Pseudomonas aeruginosa and fungi.The drug resistance of E.coli to imipenem was the lowest,about 2.6%,however,it was above 30.0% towards the most beta-lactam antibiotics;the drug resistance of Enterococcus was generally higher,about 40.0-70.0%,but vancomycin was lower,about 10.3%. CONCLUSIONS The main pathogens are Enterobacteriaceae which infect the urinary system,the drug resistance is obviously higher to the quinolones,the clinic should reasonably choose the antibiotics according to the test results of the pathogens sensitivity to drugs.
