Objective To study whether the positive psychological capital intervention could improve the level of psychological capital and the will of retention of clinical nurses. Methods A randomized controlled trials was conducted. The control group did not take any psychological intervention;Intervention group was given psychological capital intervention, which was conducted for 7 weeks (once a week, 1-2 hours per time).It used Nurses′ Psychological Capital Questionnaire and Nurses′ Retention Intention Questionnaire to evaluate the participants before and after intervention. Results There were no statistical differences between intervention group and control group in the score of Nurses′Psychological Capital Questionnaire (84.74 ± 10.04 vs. 86.16 ± 8.57,P > 0.05 ) and Nurses′ Retention Intention Questionnaire ( 19.21±3.47 vs. 18.54±3.41,P>0.05 ) on the day before intervention. The score of Nurses′Psychological Capital Questionnaire of intervention group was 93.89 ± 7.10 on the intervention day and 93.60 ± 6.88 three months later while the control group scored 84.41 ± 6.58 and 83.92 ± 9.31.The intervention group was statistically lower than the control group (t=6.156, 5.155, P<0.05) .And the score of Nurses Retention Intention Questionnaire was 22.42±2.66 on the intervention day and 22.24±2.61 three months later while the control group scored 18.61 ± 3.08 and 19.21 ± 3.47. The intervention group was statistically lower than the control group (t=5.866, 4.292, P<0.05). Conclusions Positive psychological capital intervention can improve the the will of retention of clinical nurses.

Objective To investigate the intervention effect of integrated care including exercise therapy,example learning and psychological support to ease the hematopoietic stem cell transplantation (HSCT) related complications.Methods 40 cases were divided into the intervention group and the control group according to their hospital number,there were 20 cases in each group.The intervention group received integrated care and control group adopted traditional methods.HSCT symptoms scale was used to evaluate the intervention effects in 6 time points (the day before pretreatment,the day before HSCT,the 7th day,14th day,21th day and three months after HSCT).Results There were no statistical differences between the two groups in the score of HSCT scales on the day before pretreatment.The intervention group was statistically lower than the control group in the score of HSCT scales on the day before HSCT,the 7th day,14th day,21th day and three months after HSCT,P＜0.05.Conclusion The integrated care can reduce HSCT complications and worthybe popularizing.

Objective:To present the clinical results and potential complications of modified maxillary distraction osteogenesis in the treatment of moderate to severe maxillary hypoplasia for patients with cleft lip and palate.Methods:All the cases were treated with a modified distraction osteogenesis in the Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from July 2017 to December 2019. A rigid external distraction(RED) with intranasal bone-borne traction hooks was performed after the Le Fort Ⅰ osteotomy and a maxillary internal rigid fixation was done immediately after 3-4 weeks of RED device distraction. Paired-samples t-test was used to analyze the three-dimensional reconstruction and measurements of the patient’s preoperative (T0) and immediate completion of traction (T1) cranial CT maxillofacial bony structures. Results:Fifteen patients (12 males and 3 females, ranging from 14 to 25 years in age) with moderate to severe maxillary hypoplasia were analyzed retrospectively. There were significant differences ( P<0.05) in all measures of maxillary and mandibular morphology at the completion of distraction compared to preoperatively. The mean advancement of A point (subspinale) was (10.69±9.01) mm, and the mean increase in ANB (subspinale-nasion-supramental) was (13.53±7.14)°. The average increase of alveolar plane and mandibular plane was (3.97±5.87)° and (4.65±3.67)° separately. The average growth of anterior facial height was (5.63±4.41) mm. The maxilla moved forward and downward, increasing the midface prominence and improving the facial contour. The traction process had an effect on the position of the mandible, with 5 in 15 patients experiencing moderate to severe decreased mouth opening, and the mouth opening limitation was relieved by mouth opening training after fixation at the end of distraction. One patient experienced temporomandibular joint (TMJ) dislocation, which was relieved by manual repositioning and mouth opening training after maxillary fixation and sagittal split ramus osteotomy. Conclusions:Modified maxillary distraction osteogenesis can effectively advance the maxilla, allowing clockwise rotation of mandible, improving facial contour, and significantly shortening the traction time. Limited mouth opening and TMJ dislocation may occur during traction.
