China Occupational Medicine.2024;51(4):367-373. doi:10.20001/j.issn.2095-2619.20240802

Objective To analyze the incidence of prehypertension (PHTN) and hypertension of male workers in a coal mine and investigate the influencing factors. Methods A total of 10 155 male workers in a coal mine in Shanxi Province were selected as the study subjects using the judgment sampling method. Occupational medical examination was carried out to examine the prevalence of abnormal blood pressure (including PHTN and hypertension) and its influencing factors. Results The prevalence of abnormal blood pressure was 69.9%, with a PHTN prevalence of 44.2% and a hypertension prevalence of 25.7%. The results of multinomial logistic regression analysis showed that the risk of PHTN and hypertension increased with age, drinking frequency and body mass index (all P<0.05). Workers with a pulse rate≥100 times/min had a higher risk of PHTN and hypertension than those with a pulse rate of 60-100 times/min (all P<0.05). The risk of PHTN and hypertension in workers exposed to noise, silica dust or other dust was higher than those without such occupational hazard exposure (all P<0.05). The risk of hypertension in workers with abnormal blood glucose was higher than that in workers with normal blood glucose (P<0.05). Exposure to organic solvents was associated with a higher risk of hypertension (P<0.05). Conclusion The prevalence of PHTN and hypertension among male coal miners in this mine is relatively high. The individual factors such as age, alcohol consumption, pulse rate, and body mass index, along with occupational exposure factors such as noise, silica dust, and other dusts, are influencing factors for PHTN and hypertension.

China Occupational Medicine.2024;51(4):374-380. doi:10.20001/j.issn.2095-2619.20240803

Objective To establish a trimethyltin chloride (TMT) -induced learning and memory impairment model in rats, and to investigate the protective effects and potential mechanisms of ferulic acid. Methods Specific pathogen-free male SD rats were randomly divided into control group, TMT intoxication group, fluoxetine group and 25, 50, 100 mg/kg ferulic acid group. The rats in the last five groups were injected with a dose of 8 mg/kg body weight TMT solution, and the rats in control group were injected with the same volume of 0.9% sodium chloride solution. After 24 hours of TMT injection, the rats in fluoxetine group were treated 10 mg/kg body weight of fluoxetine, the rats in the three ferulic acid groups were treated with ferulic acid at doses of 25, 50, and 100 mg/kg body weight, respectively. The rats in the control group and TMT intoxication group were treated with the same volume of 0.9% sodium chloride solution, once per day for continuous gavage for 28 days. Morris water maze experiment and light-dark box test were used to assess the learning and memory abilities of the rats. The mRNA and protein expressions of nuclear transcription factor-κB (NF-κB), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in the rat hippocampus were detected by real-time quantitative polymerase chain reaction and Western blot. The levels of reactive oxygen species (ROS) and malondialdehyde (MDA) and the activities of superoxide dismutase (SOD) and catalase (CAT) in the rat hippocampus were detected by enzyme-linked immunosorbent assay. Results Compared with the control group, rats of TMT intoxication group on day four had prolonged escape latency (P<0.05), fewer platform crossing (P<0.05), shorter time spent in the target quadrant and shorter latency to enter the dark compartment (all P<0.05). The mRNA and protein relative expression of NF-κB, TNF-α and IL-1β increased (all P<0.05), ROS and MDA levels increased (all P<0.05), SOD and CAT activities decreased (all P<0.05) in the rat hippocampus of TMT intoxication group on day four compared with that of the control group. Except for the terms of escape latency and target quadrant period of the rats in the 25 mg/kg ferulic acid group, rats in three ferulic acid groups on day four had lower escape latency (all P<0.05), more platform crossing (all P<0.05), longer period in the target quadrant and longer latency to enter the dark compartment (all P<0.05), compared with TMT intoxication group. Except for the relative protein expression of TNF-α in the rats of 50 mg/kg ferulic acid group, the mRNA and protein expression of NF-κB, TNF-α and IL-1β decreased (all P<0.05), ROS and MDA levels were reduced (all P<0.05), and the activities of SOD and CAT increased (all P<0.05) in the hippocampus of rats of 50 and 100 mg/kg ferulic acid groups compared with TMT intoxication group. Conclusion Ferulic acid can reverse TMT-induced learning and memory impairment in rats, and its mechanism of action may be related to alleviating oxidative stress damage and excessive inflammatory response in rat hippocampus.

Objective To explore the current status of posttraumatic growth (PTG) among nurses at psychiatric department and analyze its latent profiles and population characteristics. Methods A total of 357 nurses from psychiatric departments of five tertiary Grade A hospitals were selected as the research subjects using the convenience sampling method. The PTG and professional quality of life were studied using the Posttraumatic Growth Inventory and the Chinese version of the Compassion Fatigue Scale. Results The PTG score of the nurses was (56.6±23.2). The scores of compassion satisfaction, burnout, and secondary traumatic stress among nurses were (32.6±7.2), (26.9±5.9), and (26.0±5.4), respectively. The result of potential profile analysis showed that the nurses could be divided into three latent profiles based on PTG levels: low PTG group (34.4%), moderate PTG group (44.0%), and high PTG group (21.6%). The results of multinomial logistic regression analysis showed that the nurses who slept 7-8 hours per day were at higher risk of being in the high PTG group compared with those who slept more than eight hours per day (P<0.05). Psychiatric nurses who took regular exercise were at higher risk of being in the high PTG group compared with those who took irregular exercise (P<0.05). The nurses who had high job satisfaction scores were at higher risk of being in the high PTG group compared with those who had low job satisfaction scores (P<0.01). The nurses with higher compassion satisfaction scores increased the risk of being in the high PTG group compared with those with lower compassion satisfaction scores (P<0.01). The nurses with higher burnout scores increased the risk of being in the low PTG group compared with those with lower burnout scores (P<0.01). Conclusion The PTG characteristics of the nurses exhibit heterogeneity and can be categorized into three distinct profiles. Sleep duration, regular exercise, job satisfaction, compassion satisfaction, and burnout are influencing factors for the PTG latent profiles of nurses working at psychiatric department.

Objective To analyze the current status and influencing factors of elevated blood pressure among employees in a large petroleum refining enterprise in Hainan Province. Methods A total of 940 workers from a petroleum refining enterprise in Hainan Province was selected as the study subjects using the convenience sampling method. The results of their health status survey, occupational medical examination, and occupational stress measurement were collected. Results The detection rate of elevated blood pressure in the study subjects was 23.9% (225/940), with the detection rate of normal blood pressure and hypertension of 17.7% (166/940) and 6.3% (59/940), respectively. The detection rate of occupational stress was 28.8% (271/940). The result of multivariate logistic regression analysis showed that workers aged 30 -<40, 40 -<50, and ≥50 years had a higher risk of elevated blood pressure than those aged <30 years after controlling for confounding factors such as gender, residential address, length of service, education level, personal monthly income, smoking status, physical exercise, salt intake, oil intake, occupational stress, and high temperature exposure (all P<0.05). Workers in the body mass index (BMI) overweight group and obese group had a higher risk of elevated blood pressure than those in the normal group (all P<0.05). The risk of elevated blood pressure was higher in workers who drinks than those who did not (P<0.05). Workers exposed to noise levels of 85-90 dB(A) had a lower risk of elevated blood pressure compared to those exposed to noise levels >90 dB(A) (P<0.05). Conclusion Age, BMI, drinking status, and noise exposure levels are independent influencing factors for elevated blood pressure among workers in this petroleum refining enterprise. Blood pressure management should be strengthened for workers aged ≥30 years, overweight, obesity, alcohol consumption and with noise exposure intensity > 90 dB(A).

Objective To observe the clinical effects of cognitive behavioral therapy (CBT) combined with pulmonary rehabilitation on the treatment of patients with pneumoconiosis. Methods A total of 108 patients with pneumoconiosis were selected as the research subject using convenient sampling method. They were randomly divided into control group and CBT group, with 54 cases in each group. Patients in the control group were treated with conventional symptomatic treatment and pulmonary rehabilitation treatment for 12 weeks. While patients in the CBT group were treated with CBT treatment in addition to treatments of the control group. The therapeutic effect was analyzed. Results Before treatment, there was no statistical difference on score of Montreal Cognitive Assessment (MoCA), percentage of forced expiratory volume in one second to the predicted value (FEV₁%), forced expiratory volume in one second to force vital capacity ratio (FEV₁/FVC%), score of the Modified Medical Research Council Dyspnea Scale (mMRC), six minute walk distance (6MWD), Hospital Anxiety and Depression Scale (HADS) subscale scores of anxiety (HADS-A) and depression (HADS-D), and scores of Chronic Obstructive Pulmonary Disease Assessment Test (CAT), St. George's Respiratory Questionnaire (SGRQ), and serum levels of leptin, interleukin-6 (IL-6) and C-reactive protein (CRP) between the two groups (all P>0.05). After treatment, the score of MoCA, FEV₁%, FEV₁/FVC% and 6MWD increased (all P<0.05), while the scores of mMRC, HDS-A, HDS-D, CAT and SGRQ decreased (all P<0.05), and the levels of serum leptin, IL-6 and CRP decreased (all P<0.05) in the CBT group compared with the control group. Conclusion The combined treatment of CBT and pulmonary rehabilitation can better improve the cognitive ability, respiratory function, motor function, negative emotion and quality of life, and alleviate inflammatory response in patients with pneumoconiosis. It is of certain clinical application value.
