RESUMEN
Objective To analyze the identification and antibiotic resistance of non active Escherichia coli isolated from feces . Methods Clinical fecal specimens were collected from January 2013 to June 2015 for bacterial culture ,identification and antimicro-bial susceptibility testing .Results Sixty-one strains of E .coli ,inactive were detected ,18 strains of which could be agglutinated with diagnostic serum of Shigella .Three stains could produce extented spectrum β-lactamases(ESBLs);The rate of antibiotic resistance of amoxicillin and ticarcillin was 100% ,The rate of piperacillin ,cephalothin and sulfamethoxazole was 78% ,the rate of cefoxitin and amikacin was 33% ,the rate of piperacillin/tazobactam ,imipenem and meropenem was 0% .Conclusion Non active Escherichia coli can induce diarrhea ,which is easily misdiagnosed as Shigella ,the antimicrobial resistance between Escherichia coli and non active Escherichia coli is not significant difference .
RESUMEN
Objective To evaluate the clinical value of white blood cell(WBC) ,neutrophilic granulocyte percentage(NEUT% ) and C‐reactive protein(CRP) in lung infection of early chronic obstructive pulmonary disease(COPD) ,and analyse the pathogen dis‐tribution .Methods 186 cases of hospitalized patients with COPD were enrolled as research group and 60 healthy ones as control group .Compared WBC ,NEUT% ,CRP levels between the two groups .According to sputum culture results ,patients were divided into normal flora group and pathogen growth group;according to the type of pathogen ,patients were divided into G+ and G- group . Analyse WBC and CRP levels in each groups and compare sensitivity ,specificity and positive predictive value of the two indicators . Distribution of positive sputum culture results were statistically analyzed .Results The levels of three indicators in research group were higher than those in control group(P0 .05) .Based on sputum culture positive results ,the number of fungi is 86 ,and Candida albicans were the most accounting for 35 .85% .The number of bacteria were 73 strains .Differences in WBC ,NEUT% and CRP between G+ group and G- group were not significant(P> 0 .05) .Conclusion WBC ,NEUT% and CRP levels in COPD patients were higher than those in healthy group .But due to many factors which could affect the levels of WBC ,NEUT% and serum CRP ,a preliminary diag‐nosis of COPD lung infection can′t be made just through the three indicators .
RESUMEN
Objective To analyze the routine testing of vaginal discharge samples and investigate the clinical characteristics of the vaginal micro ecology of a hospital women .Methods The data of 2 533 clinical cases were included .The vaginal infection in different ages and seasons was analyzed .The clinical usefulness of bacterial vaginosis (BV) rapid diagnostic method was estimated . Results The rate of low cleanliness samples (stage Ⅲ + Ⅳ) was significantly higher than that of StageⅠ + Ⅱsamples .Of the 2 533 cases ,the detection rates of fungus and small gram negative or gram variable rods were significantly higher among specific patho‐gens and pathogenic bacteria ,respectively .The rates of low cleanliness samples were highest at age below 20 and in the season of winter (81 .3% ,73 .0% ) ,those of fungus at age from 21 to 30 and in the season of summer (23 .9% ,23 .0% ) ,and those of small gram negative or gram variable rods at age from 31 to 40 and in the season of winter (25 .1% ,37 .3% ) .In comparison with golden method ,the sensitivity and specificity of BV BLUETM method were 80 .0% and 90 .0% ,which reflected the accuracy was 87 .5% . Conclusion Vaginal infection of a hospital women was more common in young group and in the season of winter .Fungus and small gram negative or gram variable rods were the major pathogens .BV BLUETM method could assist in the BV rapid diagnosis ,with potential false positive/negative results being fully validated .
RESUMEN
Objective To analyze the relationship between the estimated glomerular filtration rate (eGFR) and 10-year car‐diovascular disease risk (10y CVDR) in Chongqing college staff .Methods The physical examination data of the staff in two univer‐sities including 2630 persons were collected in April 2013 .The eGFR and 10y CVDR of each staff were calculated according to the standardized formula .The differences of 10y CVDR among different eGFR level groups were analyzed .Results The average age of all the staff were (51 .76 ± 14 .53) years old ,which in males was significant higher than that in females (P<0 .01) .The smokers , hypertension patients and diabetes patients accounted for 16 .00% ,15 .20% and 4 .10% respectively .The smokers ,hypertension and diabetes patients in males were significantly more than than those in females (P<0 .05) .The height ,weight ,BMI ,systolic pressure , diastolic pressure ,serum creatinine ,triglyceride ,LDL and blood glucose in males were significantly higher than those in females (P=0 .000) ,while HDL in males was significantly lower than that in females (P=0 .000) .The median of 10y CVDR was 1 .25% , males were significantly higher than females (2 .85% vs .0 .40% ,P<0 .01) .The median of 10y CVDR for the following groups were 0 .74% ,2 .25% ,5 .58% and 14 .39% respectively :eGFR≥90 mL · min-1 · 1 .73 m2 ,75 mL · min-1 · 1 .73 m2 ≤eGFR<90 mL · min-1 · 1 .73 m2 ,60 mL · min-1 · 1 .73 m2 ≤eGFR<75 mL · min-1 · 1 .73 m2 ,and eGFR<60 mL · min-1 · 1 .73 m2 .The results of the one‐way analysis of variance showed that compared to the 10y CVDR of the group with eGFR≥90 mL · min-1 · 1 .73 m2 ,which of the other three groups were all significantly increased .Conclusion eGFR is a significant factor impacting 10y CVDR . The lower the eGFR level ,the higher the risk of the 10y CVDR .
