Objective Measuring job satisfaction level of community health workers,providing on the evidences for the design of the relevant policy and the evaluation of job effect.Methods 57 Community Health Service centers and 54 stations were randomly selected in 12 cities in Anhui province,and all staff on the job were investigated.The questionnaires were delivered to the working staff and anonymously filled in by them.Results The total job satisfaction average score of the staff is 110.84± 18.18.The average score of pay(10.05±2.99),welfare(10.35±3.17)and promotion(10.85±3.00)are rather low.The average score of coworkers(14.78±2.11),nature of work(14.60±2.69)and supervision (13.90±3.00)are quite high.Logistic regression analysis shows the staff's duration and title are the main factors affecting their overall job satisfaction.Conclusion The overall job satisfaction level of community health workers is not high.Establishing the reasonable system of pay,welfare mechanism and the predictable promotion space are feasible choices to promote job satisfaction of community health workers

OBJECTIVE To investigate the relationship between phenotypes and genotypes of clinical isolates of ESBLs-producing Klebsiella pneumoniae.METHODS Agar dilution method was used to test the MICs of 11 antibiotics against 67 ESBLs-producing K.pneumoniae strains.PCR was performed for amplifying ?-lactamase-encoding genes of SHV-,TEM-,and CTX-M-type,and the PCR products of some strains were cloned and sequenced to identify their gene serotypes.RESULTS With no imipenem-resistant strains among 67 strains,their resistant rates to 10 kinds of antibiotics were 10.45-89.55% The cross-resistant rates to aminoglycosides of 60 strains and to ?-lactams of 44 strains were 88.33% and 40.91%,respectively.The positive rates of SHV-,TEM-,and CTX-M-type for 67 strains were 91.04%,56.72% and 28.36%,respectively,and SHV-12,TEM-1 and CTX-M-3 genotypes were found in 7 strains by cloning and sequencing.CONCLUSIONS Sixty seven strains of ESBLs-producing K.pneumoniae present a clear feature of multi-resistance and cross-resistance to most of antibiotics except imipenem,among them there are 7 strains producing SHV-12 and CTX-M-3 extended-spectrum ?-lactamase coexistent with TEM-1 broad-spectrum ?-lactamase.

Objective: To explore the relationships of neutrophil gelatinase-associated lipocalin (NGAL) with severity of skin lesions in children with psoriasis and peripheral neutrophil count, and to evaluate in vitro effect of NGAL on expression of tumor necrosis factor-α (TNF-α) and interleukin-22 (IL-22) by a human immortalized keratinocyte cell line HaCaT. Methods: From January 1st 2017 to December 31st 2018, 98 children who newly developed psoriasis were enrolled from Department of Dermatology of 6 hospitals in China, including 51 males and 47 females. Their age was 7.00 ± 2.99 years (range: 3-14 years) , and their course of disease was 7.4 ± 5.85 days (range: 3-28 days) . The serum level of NGAL was detected in all the patients before and two weeks after treatment, and the relationships of NGAL with psoriasis area and severity index (PASI) scores and peripheral neutrophil count were evaluated. Western blot analysis and reverse-transcription (RT) -PCR were performed to determine the protein and mRNA expression of TNF-α and IL-22 in HaCaT cells, respectively, after 12-hour treatment with NGAL at concentrations of 0 (control group) , 0.125, 0.25, 0.5, 1 mg/L. Statistical analysis was carried out with SPSS 16 software. by using t test and one-way analysis of variance. Results: After 2-week treatment, the PASI score, neutrophil count and NGAL level in children with psoriasis significantly decreased (1.80 ± 1.19, [6.16 ± 0.76] × 10⁹/L, 90.86 ± 0.75 μg/L, respectively) compared with those before the treatment (10.38 ± 3.42, [11.01 ± 2.85] × 10⁹/L, 113.48 ± 21.26 μg/L, respectively; t = 31.42, 18.34, 16.37 respectively, all P < 0.001) . Before the treatment, the serum level of NGAL in the patients was positively correlated with the PASI score and peripheral neutrophil count (r = 0.918, 0.799 respectively, both P < 0.05) . The mRNA and protein expression of IL-22 in HaCaT cells significantly differed among these groups treated with different concentrations of NGAL (F = 176.31, 296.96 respectively, both P < 0.001) , so did the mRNA and protein expression of TNF-α (F = 193.28, 318.80 respectively, both P < 0.001) . Additionally, the protein and mRNA expression of IL-22 and TNF-α in HaCaT cells was significantly higher in the 0.125-, 0.25-, 0.5- and 1-mg/L NGAL group than in the control group (all P < 0.05) . The NGAL level was positively correlated with the protein and mRNA expression of TNF-α and IL-22 in HaCaT cells (all P < 0.05) . Conclusions The serum level of NGAL was high in children with psoriasis, and positively correlated with severity of skin lesions and peripheral neutrophil count. NGAL can upregulate the expression of TNF-α and IL-22 in HaCaT cells in vitro.
