Objective To research and prepare the individualized knee in vitro guided plate by 3D printing technique and to investigate the feasibility of its application in 8-plate epiphysiodesis.Methods Twelve children patients with knee varus or valgum in our hospital from January 2014 and November 2016,7 boys and 5 girls,average age of 8.2 years old,were performed the lower extremity continuous spiral CT scanning in the knee straight position.The Dicom format stored CT data were imported into software Mimics 15.0 for reconstructing the knee joint 3D model.The knee joint data after reconstruction were guided into software Geomagic1 1.0 with the.stl format.According to the demand that screws without perforating epiphyseal and joint surface,paralle ling to the epiphyseal and locating in the anterior-posterior median line of epiphyseal,the 8-plate placing screw navigation template was designed and printed by using the 3D printing technique;the 8-plate plate and screw internal fixation was conducted by intraoperative template location.The placed screw position was evaluated by postoperative CT.Results The imaging identification showed that 8-plate epiphysiodesis by using 3D printing individualized in vitro guided plate had accurate screw placement.The cases were followed from 6 months to 2 years,the satisfactory orthopedic effect was obtained in all cases.Conclusion Preparing the individualized knee in vitro guided plate by applying 3D printing technique in assisted 8-plate epiphysiodesis for treating child knee varus or valgum has accurate screw position and satisfactory effect.

Objective:To explore the clinical effects of tuina therapy of Yinyang Ruyin combined with aromatherapy on insomnia and quality of life in patients receiving perichemotherapy for breast cancer.Methods:Totally 199 inpatients with insomnia who received perichemotherapy for breast cancer from June 2018 to December 2019 and met inclusion and exclusion criteria were selected and divided into the control group ( n=48) , the tuina therapy of Yinyang Ruyin group ( n=50) , the aromatherapy group ( n=52) , and the combined treatment group ( n=49) according to the computer-generated random sequence. Patients in the control group received routine care; patients in the tuina therapy of Yinyang Ruyin group received tuina therapy of Yinyang Ruyin on this basis; patients in the aromatherapy group received aromatherapy on this basis; patients in the combined treatment group received both tuina therapy of Yinyang Ruyin and aromatherapy. After 6 cycles of chemotherapy, Pittsburgh Sleep Quality Index (PSQI) , Hamilton Depression Scale (HAMD) , and Functional Assessment of Cancer Therapy: General (FACT-G) were used to evaluate the intervention effects of the four groups. Results:The amelioration rates of insomnia in the 3 and 6 chemotherapy cycles after the intervention of the tuina therapy of Yinyang Ruyin group, the aromatherapy group, and the combined treatment group were higher than that of the control group ( P<0.05) ; the amelioration rates of insomnia in the 3 and 6 chemotherapy cycles after the intervention of the combined treatment group was higher than those of the tuina therapy of control group, Yinyang Ruyin group and the aromatherapy group ( P<0.05) . The repeated measures analysis of variance showed that the main effects of intervention in the PSQI, HAMD, and FACT-G scores of the four groups were statistically different ( P<0.05) ; the time of main effects of PSQI, HAMD, and FACT-G scores was significantly different ( P<0.05) ; there was an interaction between the intervention factors of PSQI, HAMD, and FACT-G scores and the time factor ( P<0.05) . Conclusions:Tuina therapy of Yinyang Ruyin combined with aromatherapy can ameliorate the symptoms of insomnia and depression, thereby improving the quality of life of patients.

Objective To assess the effects of action research on preventing perioperative deep venous thrombosis ( DVT ) form in patients with intracerebral hemorrhage. Methods We selected 93 cases of intracerebral hemorrhage in Neurosurgery of our hospital from 2011 to 2014. A total of 45 cases, who hospitalized from 2011 to 2012, were selected as control group and received routine nursing and perioperative routine nursing, while 48 cases, who hospitalized from 2013 to 2014, were chosen as treatment group and received action research to intervened legs exercise with four steps including plan, action, observation and reflection based on nursing of control group. Then after four steps spiral cycle, we made the plan of lower extremities excise and implemented. The incidences of DVT and rehaemorrhagia in two groups were observed. Results The rate of DVT and rehaemorrhagia were 0 in the treatment group, which were significantly lower than 13. 33% (6/45) and 4. 44% (2/45) respectively in the control group (P<0. 05). The coagulation index changes had no significantly difference between two groups. The difference of DVT had statistical significance between two groups (P<0. 01), but the difference of rehaemorrhagia had no statistical significance between two groups (P>0. 05). Conclusions Action research method is applied for plan of perioperative lower extremities excise in patients with intracerebral hemorrhage, which can decline the incidence of DVT.
