Objective: To investigate the prevalence and resistance changes of carbapenem-resistant Enterobacteriaceae (CRE) strains isolated from children patients of Chinese Bacterial Resistance Surveillance Network (CHINET) from 2005 to 2017. Methods: Antimicrobial susceptibility testing was carried out by disk diffusion method (KB method) and automated systems. Results were analyzed according to the Clinical and Laboratory Standards Institute (CLSI) 2017 edition standards. Results: Among the 4 481 CRE clinical strains, the overall prevalence of CRE in children was 6.4%, including 8.8% in neonatal period, 7.3% in infancy, 3.8% in early childhood, 4.0% in preschool, 4.7% at school age and 7.4% of puberty. The CRE prevalence of citrobacter spp. remained stable in 2005-2017, whereas other bacteria showed an upward trend, which was higher than that of the adult group (P<0.01). Among the 4 481 CRE strains, there were 2 905 strains of Klebsiella spp. (64.8%), 813 strains of Escherichia coli (18.1%), 549 strains of Enterobacter spp.(12.3%), and 65 strains of Citrobacter spp.(1.5%). Among the 4 481 CRE strains, 20.7%, 13.3%, and 11.8% were from the intensive care unit (ICU), neonatal department and internal medicine wards, respectively. Specimens were distributed as respiratory (42.8%), urine (26.3%), and blood (14.9%). The results of antimicrobial susceptibility testing exhibited that the CRE strains were highly resistant to most commonly used antimicrobial agents in clinical practice, such as imipenem, meropenem and ertapenem, as well as penicillins and cephalosporins, etc. Conclusion The prevalence of CRE strains in children is increasing year by year, and their antimicrobial resistance to common antibacterial agents in clinical practice is extremely serious, to which serious attention needs to be paid. According to the results of antimicrobial susceptibility testings, the antibacterial agents should be rationally selected to effectively control the spread of CRE.

Objective To investigate the resistance profile of clinical bacterial isolates to antibiotics in Shanghai during 2016.Methods Antimicobial susceptibility testing was carried out for the clinical isolates collected from 47 hospitals according to a unified protocol using Kirby-Bauer method or automated systems.The participating hospitals included 28 tertiary hospitals and 19 secondary hospitals across Shanghai.Results were analyzed according to CLSI 2016 breakpoints.Results A total of 122 548 clinical isolates were collected,including 35 522 (29.0％) strains of gram positive cocci and 87 026 (71.0％) strains of gram negative bacilli.Overall,28.9％ of the isolates were from secondary hospitals and 71.1％ from tertiary hospitals.Gram positive and gram negative isolates accounted for 25.8％ and 74.2％ in secondary hospitals,30.3％ and 69.7％ in tertiary hospitals,respectively.The overall prevalence of MRSA in Staphylococcus aureus was 48.7％ and 77.2％ of MRCNS in coagulase-negative Staphylococcus.The average prevalence of MRSA and MRCNS was 55.9％ and 73.3％ in secondary hospitals,45.9％ and 78.6％ in tertiary hospitals.No strains were found resistant to vancomycin in Staphylococcus.About 77.4％ of the 1 111 strains of non-meningitis S.pneumoniae isolated from children were penicillin-susceptible (PSSP),13.2％ were penicillin-intermediate (PISP) and 9.4％ were penicillinresistant (PRSP).The prevalence of PSSP,PISE and PRSP was 97.8％,2.2％,and 0 in secondary hospitals,76.5％,13.7％,and 9.8％ in tertiary hospitals.Of the 285 strains isolated from adults,94.0％,4.2％ and 1.8％ were PSSP,P1SP and PRSP,respectively.The prevalence of PSSP,PISP and PRSP among the isolates from adults was 93.7％,5.3％,and 1.0％ in secondary hospitals,94.2％,3.7％,and 2.1％ in tertiary hospitals.Overall,37 strains of vacomycin-resistant E.feacium (14 from secondary hospitals and 23 from tertiary hospitals) and 25 strains of vacomycin-resistant E.feacalis (all from tertiary hospitals) were identified.PCR and sequencing analysis indicated that most of these resistant strains were vanA type.The overall prevalence of ESBLs-producing srains was 52.2％ in E.coli,30.9％ in Klebsiella pneumoniae and 29.8％ in Proteus mirabilis.Specifically,the corresponding prevalence of such strains was 55.1％,33.6％ and 34.0％ in secondary hospitals,51.0％,29.7％ and 28.0％ in tertiary hospitals,respectively.Enterobacteriaceae strains were still highly susceptible to carbapenem antibiotics.Overall,8.9％ and 9.1％ of the Enterobacteriaceae strains were resistant to imipenem and meropenem,respectively.The figure was 6.6％ and 7.1％ in secondary hospitals,9.9％ and 10.0％ in tertiary hospitals.Extensively drug-resistant strains were identified in A.baumannii,K.pneumoniae,P.aeruginosa,and E.coli,specifically,223,63,10,and 4 strains in secondary hospitals;224,201,22,and 9 strains in tertiary hospitals.Conclusions Antibicotic resistance is still very serious in the common clinical strains,which poses a critical threat to healthcare facilities.This issue should be taken seriously and effective infection control measures must be put in place.

Objective To understand the thyroid stimulating hormone (TSH) level of neonates and iodine nutritional status of pregnant women and children in Guizhou Province.Metheds From 2016 to 2017,a city (district,county) in government location in Guizhou Province was selected as the urban survey site,and a county (city,district) whose economy was relatively backward and farther from the city (prefecture) in government location was selected as the rural survey site.In each survey site,300 salt samples were collected for determination of salt iodine;300 blood samples in the heel of neonates after birth 72 hours were taken for measurement of TSH.The Wodd Health Organization,United Nations International Children's Emergency Fund,and the International Committee for the Control of Iodine Deficiency (WHO/UNICEF/ICCIDD) recommend that when the proportion of neonates (TSH levels ＞ 5 mU/L) is ＜ 3％,the area is non-iodine-deficient.In other words,the 97th percentile (P97) value should be ≤5 mU/L.The normal reference value of the kit is ≤9 mU/L.And urinary iodine of 150 children aged 8-10 and 150 pregnant women was determined.Results A total of 5 400 edible salt samples were tested,the median of salt iodine was 27.9 mg/kg,and the consumption rate of qualified iodized salt was 94.89％ (5 124/5 400);5 400 neonatal heel blood samples were collected,the median of TSH was 2.62 mU/L,TSH P97 was 6.91 mU/L,and samples proportion with TSH ＞ 5 mU/L was 10.67％ (576/5 400),and ＞ 9 mU/L (the cut-off value of kit) was 1.00％ (54/5 400).Among 3 588 cases of children aged 8 to 10 years,the median of urinary iodine was 212.3 μg/L,those with urinary iodine ＜ 50 μg/L was 2.81％ (101/3 588),and ＜ 100 μg/L was 12.76％ (458/3 588).Among the 2 695 pregnant women,the median of urinary iodine was 163.1 μg/L,and 44.04％ (1 187/2 695) were ＜ 150 μg/L.Conclusions The quality of iodized salt is stable in Guizhou,the iodine nutrition status of children and pregnant women are good.The neonatal TSH and nutritional status of pregnant women should be monitored in the future.

Objective:To investigate the oral health knowledge awareness, attitude and behavior of children in endemic fluorosis areas of Guizhou Province, and evaluate the effectiveness of health education, so as to provide a scientific basis for improving oral health.Methods:In September 2020, 6 counties (cities and districts) were selected as survey sites from the historical fluorosis medium and severe areas in Guizhou Province. One township/village primary school was selected from each survey site to carry out health education activities for one school year. A questionnaire survey was conducted among students from grades 1 to 6 to analyze the changes in children's oral health knowledge, attitude, and behavior before and after health education and their influencing factors.Results:Before and after health education, the awareness rate of children's oral health knowledge increased from 79.22% (7 744/9 775) to 94.38% (9 169/9 715), the recognition rate of children's importance of oral health increased from 89.26% (3 490/3 910) to 95.88% (3 726/3 886), and the formation rate of children's oral health behavior increased from 62.59% (6 118/9 775) to 80.38% (7 809/9 715), with an increase of 15.16, 6.62 and 17.79 percentage points, respectively, the differences were statistically significant (χ 2 = 975.62, 15.17, 756.29, P < 0.001). The analysis of influencing factors showed that whether to stay, gender, and ethnic characteristics could significantly affect the overall score ( t = - 3.94, - 3.86, - 3.62, P < 0.001). Conclusion:The implementation of oral health education in endemic fluorosis areas in Guizhou Province has significantly improved the health knowledge, attitude and behavior of oral health among children in endemic fluorosis areas.

Objective:To investigate the awareness of iodine deficiency disorders prevention and control knowledge among residents in Guiyang City, as well as the behavioral and attitude characteristics of iodized salt consumption, and to determine the focus and direction of future health education on iodine deficiency disorders.Methods:From 0 : 00 to 24 : 00 on May 15, 2021 (the National Day for Prevention and Control of Iodine Deficiency Disorders), through the "Guizhou Disease Control" WeChat official account, the questionnaire was randomly distributed to the residents of Guiyang City who paid attention to the official account in the form of award-winning contest and returned. The survey content included general demographic data, iodine deficiency disorders prevention and control knowledge among residents and the behaviors and attitudes towards iodized salt consumption. The awareness rate of iodine deficiency disorders prevention and control knowledge among residents and the correct rate of their behaviors and attitudes towards iodized salt consumption were calculated.Results:A total of 3 078 valid questionnaires were collected in this survey. The awareness rate of iodine deficiency disorders prevention and control knowledge among residents was 51.3% (9 467/18 468), with a score of (51.26 ± 14.30) points; the correct rate of behavior and attitude towards iodized salt consumption was 93.0% (11 446/12 312), with a score of (92.97 ± 13.13) points. There was a statistically significant difference in the awareness rate of iodine deficiency disorders prevention and control knowledge among residents of different age groups (χ 2 = 23.03, P < 0.001). There were statistically significant differences in the correct rates of behavior and attitude towards iodized salt consumption among residents of different ages, ethnic groups, and professions (χ 2 = 9.66, 4.88, 24.73, P < 0.05), with lower correct rates in the ≥61 years old group, Han minority people and students. The main channels for obtaining knowledge on iodine deficiency disorders prevention and control were promotional materials (59.3%, 1 825/3 078), newspapers and magazines (56.8%, 1 747/3 078), television (56.6%, 1 743/3 078), and the internet (56.2%, 1 731/3 078). Conclusions:The correct rate of behavior and attitude towards iodized salt consumption among residents in Guiyang City is relatively high, but the awareness rate of iodine deficiency disorders prevention and control knowledge is low. We should strengthen health education for residents, especially the elderly, ethnic minorities, and students, and attach importance to promoting the safety of iodized salt and the necessity of long-term iodine supplementation.
