Centered on some theoretical researches and useful results of domestic and international literary works, this report summarized the investigation link between the personal and psychological aspects of PTSD of disaster rescue workers, and made suggestions and customers for the future study and policy-making in associated areas in China.Objective To explore the relationship between shift work and menopausal age and menstruation course of retired women. Practices During July 2017 and October 2018, the study had been performed using group sampling in nine areas of Shenzhen City to select all permanent residents (3518 men and women) with Shenzhen household enrollment for which was add up to or over 60 yrs old from the Community Health Service Centers. The data of age, marital status, menopausal age, smoking, consuming, move knowledge and shift years had been gathered. The partnership between shift work and menopausal age as well as menstruation course of professional females were analyzed by multivariate linear regression model. Outcomes There were 359 men and women (10.2%) in the move knowledge group, the menopausal age was (49.71±3.63) many years, and the monthly period period was (34.27±3.92) years. The non-shift knowledge team had been 3159 individuals (89.8%) , the menopausal age was (50.20±3.60) years, plus the menstrual duration was (34.86±4.13) many years. The differences of menopausal age and menstrual years amongst the two groups had been statistically significant (P less then 0.05) . After modifying for aspects such as for example passive smoking and drinking, the outcome of this multiple linear regression model showed that menopausal age, monthly period many years were adversely correlated with shift work (β=-0.493, -0.575, P less then 0.05) . Conclusion changes are associated with ladies menopausal age and monthly period many years, and attention ought to be paid into the influence of work strength and circadian rhythm from the work-related health of feminine workers.Objective To explore the short-term aftereffects of welding fumes on employees’ lung purpose in the welding environment preliminarily, and provide reference for future study. Methods In October 2020, the lung function of the subjects CRT-0105446 cost ended up being over repeatedly measured before and after the working shift with a panel study. The paired t test was used to compare the lung function pre and post the shift, and the linear mixed effects model ended up being utilized to evaluate the short term modifications of lung function. Results 36 male welders had been included, together with average age was (30.72±5.21) years, typical employed year was (4.36±2.17) years. And the normal concentration of welding fume was (1.27±0.49) mg/m(3). The forced vital capacity (FVC) , forced expiratory amount in the first second (FEV1) and top expiratory flow (PEF) of welders following the Plant biology change were dramatically lower than those prior to the shift (t=19.52, 48.13, 62.03, P less then 0.05) . After modifying the workers’ age, BMI and employed years, the modifications of FVCper cent and FEV1% with the concentration of welding fume were statistically significant (β=-1.02, 95%CI -1.54–0.52; β=-1.56, 95%CI -1.95–1.16; P less then 0.01) . In another term, when it comes to 1 mg/m(3) boost of welding fume within the working environment, weighed against the standard, the FVC reduces by 1.02percent, and FEV1 decreases by 1.56per cent. Conclusion Short-term exposure to welding fumes in office can reduce the lung purpose of welders.Objective A gas chromatography-tandem mass spectrometry detection way for benzene as well as its metabolites ended up being set up to produce methodological help and theoretical basis for the research of benzene toxicity process. Techniques In August 2019 to March 2020, your pet model of containing large concentration of benzene by inhalation of poison through the respiratory system of mice was set up, taken the bloodstream of mice after dyeing the poison, and also the HLB solid phase removal technique was made use of to draw out and cleanse the samples. The gas chromatography-tandem mass spectrometry recognition method ended up being used to qualitative and quantitative evaluation associated with the target substances. After divided by HP-17MS capillary chromatographic column, the substances were ionized with EI ion resource, mass spectrometry detection ended up being performed by selective ion scanning method (SIM) , and measurement was performed by additional standard curve technique. Results Benzene and its own metabolites (phenol, catechol, hydroquinone and m-trihydroxybcan be used for qualitative and quantitative detection of benzene and its metabolites (phenol, catechol, hydroquinone and m-trihydroxybenzene) precisely.Objective To investigate the worthiness of fractional exhaled nitric oxide (FeNO) when you look at the analysis of occupational symptoms of asthma (OA) , and evaluate expected genetic advance the correlation between FeNO and pulmonary function in patients with OA. Practices In October 2019, clinical datas, including pulmonary function, FeNO and blood routine test of 64 employees which applied for the diagnosis of OA in January 2012 to October 2018 in our medical center were gathered. The diagnostic value of FeNO in OA ended up being assessed, FeNO and pulmonary function in different levels of OA were compared, plus the correlations were examined.
