The Clinical Value of Combined Detection of Anti-HCG and Estradiol and Progesterone in Infertile Women / 医学研究杂志

Objective To evaluate the clinical value of combined detection serum anti-HCG and estradiol and progesterone in infertile women.Methods Serum estradiol(E2) and progesterone(P) in infertile women were detected by ECLIA , Anti-HCG were detected by ELISA.Results the levels of estradiol(E2) and progesterone(P) in anti-HCG positive group were significantly lower than those in anti-HCG negative group.Conclusions The combined detection of anti-HCG and estradiol and progesterone were of important clinical value in diagnosis of infertile women.

Pathogenic Bacteria in Respiratory Infection in Newborns:Their Distribution and Drug Resistance / 中华医院感染学杂志

OBJECTIVE To investigate the distribution and drug resistance of pathogenic bacteria which caused respiratory infection among suscepted patients and offer scientific basis for reasonable usage of antibiotics.METHODS Oropharyngeal swabs among 709 cases of respiratory infection neonates were investigated by the routine methods and drug resistance was analyzed by K-B method.RESULTS Totally 438 bacterial strains were isolated from 709 neonates.most of these bacteria were Gram-negative bacilli(70.3%),among which Haemophilus influenzae and Klebsiella pneumoniae were accounted for 39.8% and 10.3%,respectively;fungi and Gram-positive cocci were accounted for 23.5% and 6.2%.CONCLUSIONS Most strains present higher resistance rates to penicillin and ampicillin;but cefoxitin,amikacin,vancomycin,imipenem and the third generation cephalosporins are revealed with higher sensitivity rates for pathogenic bacteria in newborns.

Pathogen and Antibiotic Resistance in Very-low-birth-weight or Preterm Infants Septicemia / 中华医院感染学杂志

OBJECTIVE To understand the distribution of pathogen in very-low-birth-weight or preterm infants septicemia in early-onset and late-onset and drug sensitivity.METHODS Bacterial isolates from inpatients of very-low-birth-weight or preterm infants septicemia over a period of 3 years were retrospectively analyzed,and classified as when septicemia was happened.RESULTS The positive rate of isolates was 43.2% in 970 samples of very-low-birth-weight or preterm infants septicemia.Most of the sepsis detected by blood culture was late-onset neonatal sepsis(58.6%).Pathogen of late-onset neonatal sepsis mostly was Gram-positive cocci,Staphylococcus were found to be the most common isolates(80.5%).In early-onset sepsis group,the isolates rates of Gram-negative and Gram-positive bacteria were mostly in proportion,there were 52.4% and 47.6%,respeitively.The resistance rate of late-onset sepsis group was higher than that of early-onset one.CONCLUSIONS The key of curing infants septicemia is that we should master the distribution of pathogen of very-low-birth-weight or preterm infants septicemia in early-onset and late-onset and drug sensitivity.Antimicrobial therapy should be initiated under the guidance of anti-microbial sensitivity test,in order to avoid abuse of antimicrobial.
