ABSTRACT

Objective To study the etiology and drug resistance of escherichia coli isolated from clinic in chengde from 2016 to 2018, and to provide an objective basis for the epidemiological study and clinical rational use of antimicrobial agents. Methods The feces of 702 diarrhea patients in an outpatient clinic in chengde district from 2016 to 2018 were collected, isolated and prepared by conventional pathogen testing procedures, and the specimens suspected of escherichia coli were identified by multiple PCR and single PCR experiments. DEC was sensitized to 15 antibiotic drugs in vitro by automatic microbiological identification and drug sensitivity analyzer Vitke-2 compact. Results A total of 189 DEC strains was isolated from the feces of 702 diarrhea patients, and the detection rate was 26.92%. Among 189 DEC strains, EAEC had the highest detection rate (57.67%), followed by ETEC (32.80%), then EPEC (6.35%) and mixed (3.17%). EIEC and EHEC were not detected. The virulence genes were mainly ast A 、est Ib and esc V. All types of DEC were detected throughout the year, with the highest detection rate (29.19%) between June and August. The patients were mainly aged between 20 and 45 years old, and the detection rate was 25.86% and 27.97% for men and women. The detection of EPEC was not affected by season, sex or age, except by season and age. DEC had the highest resistance to ampicillin at 62.96%, 51.32%, 49.74% and 30.16% to cotrimoxazole, ciprofloxacin and gentamicin, and less than 20% to the other 11 drugs, all of which were sensitive to meropenem but not resistant. Among 189 DEC strains, esbl-producing strains accounted for 1.59%. Multiple resistant strains accounted for 32.80%. Conclusion DEC for chengde area of the most common bacterial pathogens in gastrointestinal tract infection, clinical laboratory should strengthen the monitoring of the region DEC, especially to carry on a variety of virulence genes, ESBL producing and multiple drug resistance strains, timely grasp the dynamics of bacterial drug resistance, and to guide clinical rational drug use, delay and reduce the generation of bacterial drug resistance.

ABSTRACT

Objective To analyze the colonization of Candida, Rhodotorula, Penicillium and Aspergillus in skin surfaces of patients with atopic dermatitis, and to assess the relationship between the four common fungal allergens and severity of atopic dermatitis. Methods Fifty patients with atopic dermatitis and 20 healthy controls were enrolled. Scales were scraped from lesional and non?lesional skin of flexural extremities of the patients, as well as from normal skin of the flexural elbow of healthy controls, then were subjected to microscopic examination and culture. Scale specimens were inoculated onto Sabouraud dextrose agar medium and cultured at 25 ℃ in a constant temperature incubator. Subsequently, suspected fungal or yeast?like colonies were collected for pure culture. Finally, fungal strains were identified according to colony morphology, color, growth speed, as well as microscopic features of spores and hyphae. Results No hyphae or pseudohyphae were found in any case by microscopic examination. Candida albicans and Rhodotorula were detected in 29(58%)and 17(34%)out of the 50 patients, respectively, and in 5(25%)and 2 (10%) out of the 20 healthy controls, respectively. The detection rates of Candida albicans and Rhodotorula were significantly higher in the patients than in the controls(χ2=6.23, 4.10, respectively, both P<0.05). Of 25 patients with severe lesions, 19(76%)and 12(48%)were colonized by Candida albicans and Rhodotorula respectively;among 25 patients with moderate lesions, 10 (40%) and 5 (20%) were colonized by Candida albicans and Rhodotorula respectively. An increase was observed in the detection rates of Candida albicans and Rhodotorula in the patients with severe lesions compared with those with moderate lesions(χ2=6.65, 4.37, respectively, both P<0.05). There was no significant difference in the detection rate of Penicillium or Aspergillus between the patients and health controls. Conclusion The colonization rates of Candida albicans and Rhodotorula on skin surfaces were higher in patients with atopic dermatitis than in healthy controls, and higher in patients with severe lesions than in patients with moderate lesions, indicating that the types of colonizing fungi are associated with the health status of skin and severity of symptoms in patients with atopic dermatitis.

ABSTRACT

Aim To investigate whether genistein pro-tects paraoxon-induced vascular endothelial dysfunction through down-regulating p22phox and Nox4 expressions as well as inhibiting the generation of ROS.Methods In this study,thoracic aortas were isolated from the male Sprague-Dawley(SD)rats and were divided into the following groups:① control group,the thoracic a-ortas were incubated with dimethyl sulfoxide (DMSO, 0.1%)for 30 min;② genistein group,the thoracic a-ortas were incubated with genistein(100 μmol·L -1 ) for 30 min;③ paraoxon group,the thoracic aortas were incubated with paraoxon at the concentration of 40.5 μmol · L -1 for 30 min; ④ paraoxon plus genistein groups,the thoracic aortas were incubated with paraoxon (40.5 μmol·L -1 )plus genistein (100μmol·L -1 )for 30 min.The expressions of p22phox and Nox4 mRNA were detected by RT-PCR and the protein expressions ofp 2 2 phox and Nox4 were detected by Western blot.Results Compared with the control group,the expressions of p22phox and Nox4 were markedly increased in the paraoxon group. In the genistein group,the expressions of p22phox and Nox4 were significantly repressed. When treated with genistein plus paraoxon,there was a marked increase in the expression of Nox4(P <0.05),but no signifi-cant difference in the expression of p22phox.The ex-pression of p22phox in the paraoxon plus genistein group was significantly decreased(P <0.05)as com-pared with paraoxin group,but there was no significant difference in the expression of Nox4.Conclusion Paraoxon may result in oxidative damage of vascular endothelium through up-regulating p22phox and Nox4 expressions,genistein may down-regulate the expres-sions of both and protect vascular endothelium.
