RESUMO
@#Objective - （ ） To evaluate the effect of job rotation on pain in wrist work related musculoskeletal disorders WMSDs （ ）Methods of physical therapists PTs . A total of 100 PTs from nine medical institutions were selected as the research subjects ， using judgment sampling method and they were divided into control group and intervention group by stratified random sampling ， method with 50 person in each group. The individuals in control group perform routine works. People in the intervention group were rotated between posts or added mobile shift replacements in daily work for 30 minutes. The duration of intervention was ， ， （ ） once a day five days a week for ten weeks. Visual Analogue Scale VAS score and pain duration were used as the evaluation ， indexes of intervention effect. The changes of indexes before intervention five weeks and ten weeks after intervention were Results ， compared between the two groups. Before intervention there was no significant difference in the VAS score and pain （ P ） duration between the control group and the intervention group all >0.05 . There was no significant difference in VAS score （ P ） and pain duration among the control group at three time points after intervention all >0.05 . The VAS score of PTs in the （P ）， intervention group at ten weeks was lower than that in the control group at the same time point <0.05 and it was lower than （ P ） that before intervention and at five weeks of intervention in the same group all <0.05 . The pain duration of PTs in the （ P ）， intervention group was lower than that in the control group at five and ten weeks after intervention all <0.05 and was lower （ P ） Conclusion ， than that before intervention at the same group all <0.05 . Rotating schedule can relieve WMSDs of PTs and the effect of intervention for ten weeks is more effective than that of intervention for five weeks.
RESUMO
Objective@#To explore the relationship between MSX1 gene detection and tooth loss in a Van der Woude syndrome (VWS) family @* Methods @# DNA was extracted from the venous blood of 2 patients with dental hy⁃podontia in the 9th family of Van der Woude syndrome (VWS) families and 62 controls with complete dentition. Primers were designed for the MSXl gene. The coding regions of exons 1 and 2 of the MSX1 gene were amplified by PCR. The purified products of exons 1 and 2 of the MSX1 gene were sequenced and analyzed by sequence alignment @*Results@#The ivs2+68 C>T polymorphism in the MSX1 gene was found in the VWS9 members with tooth loss, and the VWS pa⁃tients with IRF6 gene mutations had increased tooth loss@* Conclusion@#Congenital tooth loss in the patients with con⁃genital missing teeth in VWS family 9 may be related to the ivs2 + 68 C> T polymorphism of the MSX1 gene.
RESUMO
@#In patients with anterior teeth loss, especially in patients with soft tissue defects, the aesthetic problem of soft tissue is still a major problem in the delayed planting restoration. In the restoration of anterior teeth, the health of the soft tissue around implants play a key role in guaranteeing the long-term success of dental implants. Therefore, consideration is worth being taken that how to deal with the soft tissue during the process of the delayed implant restoration as well as how to evaluate the effects after treatment. According to the process of the delayed implant operation sequence therapy-preoperative, intraoperative and postoperative treatment, this article will have a literature review and summary through these aspects as followings: the red aesthetic evaluation index, treatment of soft tissue around delayed implant, clinical curative effect evaluation.
