Application of precision medicine in the field of surgery / 南方医科大学学报

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.

Epidemiological study of postpartum depression among migrant women at Tianhe District of Guangzhou / 实用医学杂志

Objective To investigate the prevalence and risk factors of postpartum depression among female immigrants at Tianhe district of Guangzhou. Methods A total of 2021 migrant women postpartum in three hospitals at Tianhe district of Guangzhou were screened with Center for Epidemiological Survey Depression Scale , (CES-D), Social Support Rating Scale(SSRS) and self-made related factors questionnaire from May to December, 2013. Results This study showed postpartum depression affected 18.31% of migrant women at Tianhe district of Guangzhou. Unconditional logistic regression analysis showed a significant correlation of PPD with birth place , residence time,newborn disease,fetus gender and household income (P < 0.05). Multivariate logistic regression analysis identified birth place,residence time,newborn disease,fetus gender as the risk factors for PPD,household income was negatively correlated with the incidence of PPD with OR value of 0.680;Compared with healthy female immigrants, the total score of social support rating scale,the score of objective support,subjective support and social utilization degree were significantly reduced respectively in female immigrants with PPD. Conclusion The prevalence of PPD was high at Tianhe district of Guangzhou,health education and comprehensive social support system should be offered in order to prevent PPD.

Postoperative rehabilitation strategy for acetabular fracture: application of 3D printing technique / 南方医科大学学报

<p><b>OBJECTIVE</b>To explore the value of 3D printing technique in the surgical management and strategy of rehabilitation therapy of acetabular fracture.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>The operation was completed successfully with a shortened postoperative recovery time.</p><p><b>CONCLUSIONS</b>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.</p>

Prevalence and risk factors of postpartum depression in Tianhe District of Guangzhou / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the prevalence and risk factors of postpartum depression (PPD) in Tianhe district of Guangzhou.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>The prevalence of PPD is high in Tianhe District of Guangzhou, and health education and psychosocial intervention should be offered to prevent PPD.</p>
