Work-related musculoskeletal disorders (WMSDs) refer to musculoskeletal disorders caused by work or work as the main cause, which are characterized by high prevalence and heavy burden of disease as a global problem. The classification and catalog of occupational diseases is of great significance for guiding the prevention and control of occupational diseases and safeguarding the rights and interests of workers. The types of WMSDs included in the list of occupational diseases vary greatly from country to country, and the regulations on specific pathogenic factors are also inconsistent. By sorting out and analyzing the lists and characteristics of WMSDs at home and abroad, and using the International Statistical Classification of Diseases and Related Health Problems (ICD-10) in occupational health to standardize of WMSDs in various countries, which would lay the foundation for future multi-country WMSDs occupational health registration and disease burden research, and provide a reference for China to revise the WMSDs list.

4.Symptom prevalence and Primary intervention of work-related musculoskeletal disorders and their related factors among manufacturing workers.
Korean Journal of Occupational and Environmental Medicine 2005;17(2):116-128
OBJECTIVES: To investigate the symptom prevalence and the primary intervention of work-related musculoskeletal diseases(WMSDs) and their related factors among manufacturing workers. METHOD: A self-administered questionnaire survey was conducted on 2,457 workers, at 22 enterprises in Chungnam province, Korea, from September 1 to December 1, 2003. The contents of the questionnaire included general and work-related characteristics, musculoskeletal symptoms and workers' past one-year experience of primary interventions. RESULTS 1. The overall symptom prevalence of the musculoskeletal diseases was 23.9%. The WMSD symptom prevalences at the neck/shoulder, arm/elbow, hand/wrist and back/leg were 14.8%. 2.7%. 7.3% and 12.0%, respectively. 2. In multivariate analysis, all WMSD symptom prevalences were high in the high workload, high force & high repetitiveness, and 'high job strain' groups. The WMSD symptom prevalence at neck/shoulder was also high in females and the group experiencing low social support from the supervisor. 3. The rates of the primary interventions were as follows : 13.7% for health education, 5.8% for health counselling, 18.8% for preventive exercise, 24.7% for ergonomic intervention, and 9.8% for administrative intervention. 4. In multivariate analysis, the size of the enterprises and the type of occupational health management system(OHMS) were significantly associated with all primary interventions except health counselling(p<0.05). The other individual-level predictive factors were as follows. Those for the health education were male and union presence. Those for the health counselling were older age(> or =40 years), irregular employment, and the active group of Karasek's job strain model. Those for the preventive exercise were male, older age, longer tenure and regular employment. Those for the ergonomic intervention were longer tenure, job of physical force and/or repetitiveness, high job stain and the group experiencing high social support from the supervisor. The predictive factor for the administrative intervention was male (p<0.05). CONCLUSIONS: To establish an effective strategy for the primary prevention of WMSDs, approaches are needed which consider the individual nature of small and medium sized enterprises. IAlso necessary is to promote the participation of labor and management because the activation of the primary intervention was associated with the type of OHMS and union presence. Moreover the reduction of workload and increased intervention into the high risk group could be effective in the prevention of WMSDs.

OBJECTIVETo explore the effect and the mechanism of Danhong Injection (DI), Ligustrazine Injection (LI), and adsorbable biomembranes in preventing the adhesion of tendons and tissues.
METHODSTotally 120 patients all suffering from simple flexor digitorum tendon rupture on the hand zone two damaged by sharp weapons were randomly assigned to Group A (Dikang adsorbable biomembrane), Group B (Tianxinfu adsorbable biomembrane), Group C (Tianxinfu adsorbable biomembrane + Ligustrazine group), and Group D (Tianxinfu adsorbable biomembrane + DI group) in accordance with random digit table, 30 cases in each group. Indicators such as total active movement (TAM) of the hand tendon, Minnesota manual dexterity test (MMDT), and finger flex strength test (FFST) were observed.
RESULTSThe TAM and the favorable rate were higher in Group C and D than in Group A and B at post-operative 4 and 8 week (P < 0.05, P < 0.01). There was no statistical difference between Group C and D (P > 0.05). Each index of MMDT was lower in Group C and D than in Group A and B (P < 0.05). There was no statistical difference in FFST among all the 4 groups (P > 0.05).
CONCLUSIONSCombined application of LI or DI with Tianxinfu adsorbable biomembranes could effectively prevent the adhesion of tendons. DI showed equivalent effect as LI did. Besides, the combined application was superior in preventing adhesion to using Xintianfu adsorbable biomembrane or Dikan adsorbable biomembrane alone.

BACKGROUND:
Age-related musculoskeletal diseases are becoming increasingly burdensome in terms of both individual quality of life and medical cost. We intended to establish a large population-based cohort study to determine environmental, lifestyle, and genetic risk factors of musculoskeletal and other age-related diseases, and to clarify the association between vitamin D status and such diseases.
METHODS:
We targeted 34,802 residents aged 40-74 years living in areas of northern Niigata Prefecture, including Sekikawa Village, Awashimaura Village, and Murakami City (Murakami region). The baseline questionnaire survey, conducted between 2011 and 2013, queried respondents on their lifestyle and environmental factors (predictors), and self-reported outcomes. Plasma 25-hydroxyvitamin D (25[OH]D) concentration, an indicator of vitamin D status, was determined with the Liaison® 25OH Vitamin D Total Assay. The primary outcome of this study was osteoporotic fracture; other outcomes included age-related diseases including knee osteoarthritis, perception of chronic pain, dementia, and long-term care insurance use. Mean ages of men and women were 59.2 (SD = 9.3, N = 6907) and 59.0 (SD = 9.3, N = 7457) years, respectively. From the blood samples provided by 3710 men and 4787 women, mean 25(OH)D concentrations were 56.5 (SD = 18.4) nmol/L (22.6 ng/mL) and 45.4 (SD = 16.5) nmol/L (18.2 ng/mL), respectively.
DISCUSSION
Follow-up surveys are planned every 5 years for 15 years, and incident cases of our targeted diseases will be followed at hospitals and clinics in and nearby the cohort area. We anticipate that we will be able to clarify the association between vitamin D status and multiple disease outcomes in a Japanese population.
