ABSTRACT
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.
ABSTRACT
OBJECTIVE: To investigate the prevalence of occupational musculoskeletal disorders(OMD) in workers of manufacturing industry,and to analyze its influencing factors.METHODS: A total of 1 168 first-line workers from 3manufacturing enterprises were selected as study subjects using convenient sampling.The self-designed questionnaire was used to investigate the basic information and the ergonomics of work process.The Nordic Musculoskeletal Questionnaire was used to investigate the prevalence of OMD.The workers were divided into non-OMD group and OMD group.RESULTS: The prevalence of OMD in these 1 168 workers was 34.9%.Comparing with the non-OMD group,the score of using auxiliary tools to carry the weights in the OMD group was higher(P<0.01),and the scores of straight waist and bent knees when transporting heavy object was lower(P<0.01).Logistic regression analysis showed that male workers had a higher risk of OMD than female workers(P<0.05).The longer the length of service,the greater the risk of OMD(P<0.01).Shift workers had the higher risk of OMD than non-shift workers(P<0.01).The higher scores of using auxiliary tools to carry the weights and straight waist and bent knees when transporting heavy object(it mean that less use of the above labor behavior and posture),the greater the risk of OMD(P<0.05).CONCLUSION: Sex,length of service,shift,labor behavior and posture are the influencing factors of OMD.
ABSTRACT
ObjectiveTo observethe clinical efficacy of surround needling plus high-energy red light in treating herpes zoster. MethodSixty patients with herpes zoster were randomized into a medication group, a control group and a united group. The medication group was intervened by oral administration of medication, the control group was by surround needling plus electroacupuncture in addition to the medication, and the united group was by the medication, surround needling plus electroacupuncture, and the high-energy red light radiation. The effect on pain and the comprehensive therapeutic efficacy were evaluated on treatment day 5 and day 10.ResultThe efficacies in releasing pain in the control group and united group were significantly superior to that in the medication group on treatment day 5 (P0.05); on treatment day 10, the effects on releasing pain in the control group and united group were more significant than that in the medication group (P0.05); on treatment day 10, the efficacies in the control group and united group were significantly better than that in the medication group (P<0.01), and the efficacy in the united group was superior to that in the control group (P<0.05). ConclusionSurround needling plus high-energy red light can effectively reduce the neuralgia caused by herpes zoster, shorten the pain duration, improve the symptoms, andthus this combination is an effective and safe method.
ABSTRACT
AIM: To investigate the effect of l menthol on the absorption of ciprofloxacin (Cip) via the mucosa. METHODS: Mucosa absorption experiment and deposit effect were made on a two cells diffusion apparatus in vitro to calculate permeation coefficients. RESULTS: With increasing of the concentration of Cip, the permeation coefficient of mucosa absorption showed a increasing tendency, but deposit effect declined significantly. After using l menthol, the permeation coefficient of Cip showed a declining tendency. Especially at 0.2 percent concentration of l menthol, the decrease level was more obvious than other groups (P
