Precision medicine, based on personalized medicine, is to provide personalized and precise treatment. The emergence of 3D printing technique as well as genome sequencing provides an effective way to realize precise and personalized treatment. The application of 3D printing technique in the field of surgery is listed as following: optimize operation plan to achieve precise and personalized surgery; design personalized navigation template; personalized prosthesis production; design of personalized tissue and organ. With the development of tissue engineering, new material technology and genome sequencing and the improvement in related polices and regulations, precision medicine will step on a higher level in the field of surgery. This review introduces the application of precision medicine in the field of surgery.

Objective: To explore the value of 3D printing technique in the surgical management and strategy of rehabilitation therapy of acetabular fracture., Methods: For a patient with acetabular fracture, the pelvis model was printed preoperatively by 3D printing technique for surgical simulation to determine the optimal position of the screw, measure the screw length, and design the route of screw entry. Laparoscopic assisted internal fixation was performed, and a gradual and systematic rehabilitation plan was carried out after the surgery based on the results of simulation., Results: The operation was completed successfully with a shortened postoperative recovery time., Conclusions: The application of 3D printing allows more accurate and safer surgical management of acetabular fracture to promote postoperative recovery of the patient and lower the medical costs.

Objective: To investigate the prevalence and risk factors of postpartum depression (PPD) in Tianhe district of Guangzhou., Methods: A total of 1428 postpartum women in 3 hospitals in Tianhe District of Guangzhou were screened with Edinburg Postnatal Depression Scale (EPDS), Social Support Rating Scale (SSRS) and a self-designed questionnaire of PPD-related factors during the period from May to September, 2013., Results: The prevalence of PPD was 20.03% in these women. Unconditional logistic regression analysis showed a significant correlation of PPD with education, delivery mode, only daughter, relationship between mother-in-law and daughter-in-law, newborn gender satisfaction and housing condition (P<0.05). Multivariate logistic regression analysis identified education, delivery mode, only daughter, relationship between mother-in-law and daughter-in-law, and newborn gender satisfaction as the risk factors for PPD, and housing condition was negatively correlated with the incidence of PPD with an OR value of 0.900. Compared with healthy postpartum women, the patients with PPD exhibited significantly reduced total score of social support rating scale, score of objective support, score of subjective support, and social utilization degree., Conclusion: The prevalence of PPD is high in Tianhe District of Guangzhou, and health education and psychosocial intervention should be offered to prevent PPD.
