Can the water resources tax policy effectively stimulate the water saving behavior of social water users? A DSGE model embedded in water resources tax.

Whether the implementation of the water resources tax policy can stimulate the water-saving behavior of social water users is one of the important criteria for evaluating the implementation effect of the tax reform policy. Taking Hebei Province, the first tax reform pilot in China, as an example. A dynamic stochastic general equilibrium model (DSGE) with embedded water resources tax is constructed to simulate the persistent impact of water resources tax on water-saving objectives. The research shows that: (1) Water resources tax can effectively achieve the goal of water-saving and improve the utilization efficiency of water resources. (2) Levying water resources tax helps to improve the water-saving awareness of enterprises and residents. It can also encourage enterprises to optimize production structures. (3) Rational and efficient use of special water resources protection funds is the basis for ensuring the effective implementation of water resources tax. It can also improve the recycling capacity of water resources. The results show that the government should speed up formulating a reasonable water resources tax rate and accelerate the construction of water resources tax protection measures. To ensure the relatively steady state of water resources utilization and protection, and achieve the dual goals of sustainable economic development and sustainable use of water resources. The research results of this paper reveal the internal logic of the comprehensive impact of water resources tax on the economy and society and provide an important basis for the national promotion of tax reform policy.

A clinical study on clinical features,manifestations and drug resistance of melioidosis.

Objectives: To explore the clinical features, manifestations and drug resistance of melioidosis. Methods: The clinical data of 45 melioidosis patients treated by Affiliated Haikou Hospital of Xiangya Medical College, Central South University during January 2015 and January 2020 were studied. Informaiton collected included age, birthplace, area of residence, sex, ethnic group, clinical symptoms or signs, colony culture results, degree of drug resistance, treatment regimens and outcomes, department of initial diagnosis, and specimen type, thereby giving an analysis of the clinical features, manifestations, and treatment outcomes of the disease. Body fluids were obtained from all patients to analyze the drug resistance of the bacterium Burkholderia pseudomallei based on colony culture and susceptibility test results. Results: In the 45 cases of melioidosis, the clinical manifestations predominantly included low fever (31.11%), pulmonary infection (22.22%); auxiliary examinations often suggested increases in C reactive protein (CRP) (73.33%), white blood cell count (#WBC) (68.89%) and procalcitonin (PCT) (66.67%); susceptibility test results showed that Burkholderia pseudomallei yielded high sensitive rate to antibacterials including trimethoprim-sulfamethoxazole (SXT) (88.89%),ceftazidime (CAZ)(93.33%), meropenem (MEM) (100.00%), imipenem (IPM)(100.00%); Of the 45 melioidosis patients, 23 were cured (51.11%), and 21 showed an improvement (33.33%) or remained stable (13.33%); A relatively high percentage of the patients experienced post-discharge recurrence/aggravation (recurrence within six months: 4.44%; recurrence within a year: 6.67%). Conclusions: Low fever, pulmonary infection, and increases in serum inflammatory markers are major clinical features of melioidosis. Burkholderia pseudomallei presents high resistance rates to antibacterials such as GEN, FEP, AMP, and IPM.

Parental influences on weekend screen time among preschool children in Nanjing / 中国学校卫生

Objective@#To understand weekend screen time of preschool children in Nanjing, Jiangsu and to explore its association with parental factors,aiming to provide effective strategies for screen time intervention.@*Methods@#A questionnaire survey was conducted in 6 424 parents of preschool children in 20 kindergartens selected using convenience samping method in Nanjing to understand the association of screen time during weekends and parental factors.@*Results@#The proportion of preschool children in Nanjing with screen time ≥2 h/d was 13.01%, among which the proportion of boys was 14.61%, and girls was 11.34%. The difference was statistically significant(χ2=15.27, P<0.01). Logistic regression analysis showed that there was a positive correlation between 3.5-6 years old, boys, paternal education lower than junior high school or equal to senior high school, and no exercise habits with children’s screen time ≥2 h/d(OR=1.43, 1.42, 2.21, 1.82, 2.47, 2.05, 1.36, 1.38, 1.39, 1.52, P<0.05).@*Conclusion@#The video screen time of 3-6 year old preschool children in Nanjing is at moderate level. Parents’ exercise habits and education shows impact on screen time of preschool children, and should be given attention and support.

Health literacy among parents of children and adolescents in Nanjing / 中国学校卫生

Objective@#To understand health literacy among parents of children and adolescents in Nanjing and to provide support and suggestions for health literacy improvement.@*Methods@#A total of 3 412 elementary school students from 6 primary schools were selected to conduct a survey on health literacy during April to May 2017 through convenient sampling method.@*Results@#About 21.69% of parents in Nanjing had proficient health literacy, especially in the understanding of smoking cessation (98.24%). About 98.62% of parents gave correct answer on daily driving method, and 99.79% in skills needed for escaping in a fire, which was 99.79%. Parental health literacy significantly improved as educational attainment increases, from 11.80% to 35.69% for paternal and from 11.98% to 38.38% for maternal educational attainment (χ2=111.46, 114.58, P<0.01); Proportion of proficient health literacy was highest (95.43%) among fathers being professional technicians, and was highest (97.53%) among mothers being professional and technical personnel was 97.53%. Significant differences were found across different parental occupation (χ2=228.95, 218.79, P<0.01).@*Conclusion@#Health literacy should be strengthened among parents in Nanjing to support their children, especially among those with low educational attainment.

Molecular typing and antimicrobial susceptibility profiles of Campylobacter jejuni isolates from north China.

To obtain the genotype and antimicrobial susceptibility profiles of Campylobacter jejuni isolates from north China, 93 C. jejuni isolates (56 isolates from patients with diarrhoea, 7 isolates from Guillain-Barré syndrome patients and 30 isolates from chicken stools) were selected for multilocus sequence typing (MLST), PFGE and drug resistance testing. A total of 49 sequence types (STs) were identified from the entire panel of 93 C. jejuni isolates. Fifty-six isolates belonged to 14 clonal complexes, while 37 isolates could not be assigned to any known clonal complex. The most frequently observed clonal complexes were ST-21 (11 isolates), ST-353 (10 isolates) and ST-443 (6 isolates). Fifty-three PFGE SmaI patterns were identified among 93 isolates. No erythromycin-, gentamicin- or streptomycin-resistant isolates were found among the 44 strains isolated in 2008. Resistance to nalidixic acid, levofloxacin and ciprofloxacin was observed in 100 % (44/44) of the tested isolates. This study has shown the genetic characteristics of C. jejuni isolates in north China. In addition, overlapping clonal groups were defined by both MLST and PFGE for C. jejuni human and chicken isolates.
