ABSTRACT
Objective@#To explore the effect of comprehensive rehabilitation treatment of individualized exercise program on lung function, exercise ability, quality of life and biochemical indexes of coal workers’ pneumoconiosis patients, and to provide scientific and effective methods for rehabilitation treatment of coal workers' pneumoconiosis.@*Methods@#In Huaibei Coal Mine Occupational Disease Prevention and Control Hospital, the data of pneumoconiosis patients treated by pneumoconiosis department in the hospital were collected and sorted out. 80 patients were selected according to the inclusion and exclusion criteria. Using a random number table, they were randomly divided into two groups with 40 cases in each group. The data investigated in this study include the results before and after treatment. Pulmonary function index, BMI index, six-minute walking distance (6MWD) , quality of life questionnaire (SF-36) , hospital anxiety and depression scale (HADS) , st George's breathing questionnaire (sgrq) , c-reactive protein (CRP) and blood oxygen saturation (SpO2) were used to evaluate and compare the efficacy of the two groups.@*Results@#The lung function indexes of the test group were significantly higher than those of the control group after treatment (P<0.05) , including forced vital capacity, forced vital capacity in the first second, maximum expiratory flow, expiratory flow when vital capacity was 75% and expiratory flow when vital capacity was 25%. The forced vital capacity, the first-second forced vital capacity and the maximum expiratory flow of the patients in the test group were higher after treatment than before (P<0.05) . The six-minute walking distance of the test group was greater than that of the control group after treatment (P<0.05) . After treatment, the scores of st George’s breathing questionnaire in the test group were lower than those in the control group (P<0.05) . The scores of quality of life questionnaire in the test group were higher than those in the control group after treatment (P<0.05) .@*Conclusion@#The comprehensive rehabilitation treatment of individualized exercise program improved the endurance and exercise ability of pneumoconiosis patients, improved the respiratory status and quality of life of pneumoconiosis patients in Huaibei Coal Mine, improved the lung function of pneumoconiosis patients, and improved the forced vital capacity of patients, but the small airway function has not been significantly improved.
ABSTRACT
OBJECTIVE: To analyze the tendency of incidence in coal workers' pneumoconiosis( CWP) in different time of dust exposure and different types of work in a mining enterprise in Huaibei City. METHODS: A total of 12 152 dust exposed workers who worked from 1970 to 2014 in a mining enterprise in Huaibei City were chosen as study subjects by judgment sampling method. They were divided into 2 cohorts were formed according to initial year of dust exposure( 1970-,1980-),and 4 group according to the type of work( tunneling,mining,combining and helping). Life table method was adopted to calculate cumulative life-incidence of CWP in each cohort. RESULTS: Among 12 152 workers,there were 594 of them diagnosed as CWP patients with a 4. 89% of incidence. During the same 34-year-observation period,the cumulative CWP incidence of 1970-cohort was higher than that of the 1980 s( 8. 03% vs 5. 45%,P < 0. 01). The cumulative CWP incidence of tunneling,mining,combining and helping workers were 69. 33%,40. 53%,36. 66% and 19. 70% by 2014,respectively. The cumulative incidence of CWP in tunneling group started to rise from the 14-year-observation window,mining's from 16-year-observation window,combining and helping workers from 18-year-observation window. Among the workers in 1970-cohort at the 34-year-observation window,the CWP cumulative incidence in mining group was the highest( 33. 83%,P < 0. 004),and combining's was the lowest( 2. 28%,P < 0. 004). Among the workers in 1970-cohort at the 44-year-observation window,the CWP cumulative incidence in tunneling group was the highest( 66. 66%,P < 0. 004),and helping's was the lowest( 27. 24%,P < 0. 004). Among the workers in 1980-cohort at the 34-year-observation window,the CWP cumulative incidence in tunneling group was the highest( 29. 87%,P < 0. 004). CONCLUSION: The cumulative incidence of CWP patients was slowed down with prolonged dust exposure starting time. There were differences among different types of workers with different starting time of dust exposure.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of secondary dust exposure after whole-lung lavage (WLL) on the clinical symptoms, arterial blood gas parameters, and pulmonary function in subjects with pneumoconiosis and patients with stage I coal workers' pneumoconiosis (CWP).</p><p><b>METHODS</b>The subjects with pneumoconiosis and patients with stage I CWP who underwent WLL in our hospital during the study period were selected. All patients were divided into postoperative dust exposure group (n = 86) and lavage control group (n = 86) according to whether they were exposed to dust after conventional operation. In addition, their workmates with similar age, history of dust exposure, and type of dust exposure were selected as non-lavage control group (n = 86). Follow-up was performed before and at one month and one year after WLL to evaluate clinical symptoms, arterial blood gas parameters, and pulmonary function.</p><p><b>RESULTS</b>One month after operation, the clinical scores of the postoperative dust-exposure group and lavage control group were significantly reduced compared with their preoperative scores and the clinical score of the non-lavage control group (P < 0.01). One year after operation, the clinical scores of the postoperative dust-exposure group and lavage control group were significantly reduced compared with their preoperative scores and the clinical score of the non?lavage control group (P < 0.01), and the lavage control group had a significantly lower clinical score than the postoperative dust exposure group (P < 0.01). One month after operation, the arterial partial pressure of oxygen (PaO2) of the postoperative dust-exposure group and lavage control group were significantly higher than their preoperative values and the arterial PaO2 of the non-lavage control group (P < 0.01). One year after operation, the lavage control group had significantly higher arterial PaO2 than the postoperative dust exposure group and the arterial PaO2 of the non-lavage control group was significantly lower than its preoperative value and the arterial PaO2 of the postoperative dust exposure group and lavage control group (P < 0.05 or P < 0.01); the postoperative dust exposure group showed a significant decrease in arterial PaO2 (P < 0.01), while the lavage control group showed a significant increase in arterial PaO2 (P < 0.01). The partial pressure of carbon dioxide showed no significant differences between the three groups before and at one month and one year after operation (P > 0.05).</p><p><b>CONCLUSION</b>Dust exposure should be avoided after WLL to ensure the treatment outcome.</p>
