Objective:To investigate the clinical efficacy of low-energy laser in the treatment of erosive oral lichen planus (OLP) and its effect on patients' pain.Methods:Eighty-six patients with erosive OLP who were treated in Shanxian Central Hospital from February 2018 to January 2020 were included in this study. They were randomly divided into control and observation groups ( n = 43/group). The control group was treated by local injection of dexamethasone, and the observation group was treated with semiconductor low-energy laser irradiation. All patients were treated for 8 weeks. Pain scores and physical sign score before and after treatment were evaluated in each group. Therapeutic effects were compared between the two groups. Area of lesion was measured in each group. Recurrence of erosive OLP was calculated at 3 and 6 months after surgery. Results:Before treatment, there were no significant differences in visual analogue scale (VAS) score and physical sign score between the two groups (both P > 0.05). At 7, 14, 28 and 56 days after treatment, VAS score and physical sign score were significantly decreased in each group compared with those before treatment, and VAS score and physical sign score in the observation group were significantly lower than those in the control group (all P < 0.05). Total response rate in the observation group was significantly higher than that in the control group [93.02% (40/43) vs. 83.72% (36/43), χ2 = 1.81, P > 0.05). Before and 1 month after treatment, there was no significant difference in area of lesion between control and observation groups (both P > 0.05). At 3 and 6 months after surgery, area of lesion in the observation group was (0.31 ± 0.14) cm 2 and (0.32 ± 0.12) cm 2, respectively, which were significantly smaller than those in the control group [(0.42 ± 0.18) cm 2, (0.48 ± 0.19) cm 2, t = 3.16, 4.67, both P < 0.05). At 3 and 6 months after treatment, recurrence of erosive OLP in the observation group was 2.33% (1/43) and 13.95% (6/43), respectively, which were significantly lower than those in the control group [13.95% (6/43), 37.21% (16/43), χ2 = 3.89, 6.11, both P < 0.05]. Conclusion:There is no significant difference in the short-term efficacy of low-energy laser versus conventional corticosteroids in the treatment of erosive OLP. However, low-energy laser has a more obvious short-term pain relief effect than conventional corticosteroids. It can accelerate the healing of injured tissue and decrease the recurrence rate of erosive OLP.
Résumé
Object the current radiological health situation of different ranks medical institutions of interventional radiology in a city of Pearl Delta. Methods all the medical institutions in the city, which had carried out interventional radiology before December 31, 2019 as the research objects by survey. By using the method of field epidemiological investigation, the basic situation of general messages, the status of protective facilities, environmental radiation does, personal protective equipment, occupational health monitoring were investigated. Results There were 12 interventional radiology equipment and 180 employees in 7 medical institutions in the city, before December 31, 2019. There was no statistical significance in the composition of employees of different ranks medical institutions (P > 0.05). There was no statistical significance in the composition of protective facilities for interventional treatment in different ranks hospitals (P > 0.05). The environmental radiation dose in interventional radiology devices room of grade A class 3 hospital was higher than that of grade A class 2 hospital (P < 0.05). There was no statistical significance in the composition of individual protective equipment for interventional therapy in different ranks medical institutions (P > 0.05). The proportion of occupational health examination before work and during work in grade A class 2 hospital was higher than A class 3 hospital (P < 0.01). Conclusion The current situation of radiological health of different ranks medical institutions of interventional radiology in a city of Pearl Delta was good momentum. It may be helpful to improve the radiological health protection level of interventional therapy in this city by strengthening the radiological protection management of applying for interventional therapy, actively carrying out the evaluation of radiological protection against occupational disease hazards in construction projects, and urging the employee to carry out the occupational health monitoring inspection as required.

Objective@#To study the correlation of occupation musculoskeletal disease (OMD) and safety behavior in assembly line workers.@*Methods@#Selected assembly line workers of 3 manufacturing factory in Pacity as the objects of this study by judgement sampling. Questionnaires were used for messages collection including the general sociodemographic characteristic, OMD condition, occupational safety behaviors.@*Results@#This study shows that, 826 OMD workers were found that the annual prevalence was 38.03%. The scores of work posture, handling habits, health habit in OMD group was lower than non-OMD group (P<0.01) but personal protection behavior was higher than non-OMD group (P<0.01) . Test of binary logistic regression revealed that age, workage, work posture, handling habits were the factors of OMD (P<0.01) .@*Conclusion@#Safety behaviors were the potent factors of OMD that work posture and handling habits should be broadcast.
