Objective:To explore the application value of minimally invasive plate osteosynthesis(MIPO)and open reduction and internal fixation(ORIF)in patients with middle and lower humeral shaft fractures.Methods:A total of 32 patients with middle and lower humeral shaft fractures treated with MIPO in our hospital from Jun 2020 to Sep 2023 were selected as the observation group,and another 32 patients with middle and lower humeral shaft fractures treated with ORIF were selected as the control group.The perioperative relevant indicators,fracture healing time,pain factors[substance P(SP),prostaglandin E2(PGE2)],pain severity score,upper limb function(Neer score for shoulder joint,Mayo score for elbow joint)before and after surgery,and complications were compared between the two groups.Results:The operation time,incision length,wound healing time,hospitalization time,fracture healing time,and complete weight-bearing time in the observation group were shorter than those in the control group,and the intraoperative blood loss was lower in the observation group(P＜0.05).The levels of serum SP and PGE2 in the observation group were lower than those in the control group at 3 and 5 days after surgery(P＜0.05).The pain scores in the observation group were lower than those in the control group at 1,3,and 5 days after surgery(P＜0.05).The Neer score of the shoulder joint and the Mayo score of the elbow joint in the observation group were higher than those in the control group at 1,3,and 6 months after surgery(P＜0.05).There was no significant difference in the Neer score of the shoulder joint and the Mayo score of the elbow joint between the two groups at 12 months after surgery(P＞0.05).There was no significant difference in the total incidence of complications between the two groups(P＞0.05).Conclusion:Both MIPO and ORIF have good long-term effects and safety in the treatment of middle and lower humeral shaft fractures,but the former can reduce injury,reduce pain,promote fracture healing,and has significant advantages in improving upper limb function in the early stage.

Objective To investigate the effect of single operation Mammotome system on breast benign tumor patients.Methods 86 cases of benign breast cancer patients admitted from Jan.2011 to Dec.2015 were divided into the control group (43 cases) and the observation group (43 cases) according to the random number table method.The control group were treated by traditional breast lesion resection and the observation group were treated by single operation of Mammotome system.The mean time of operation,the average blood loss and the size of surgical scar were recorded.The number of patients with deformity of breast and complications was recorded.The satisfaction of the two groups was evaluated by questionnaire.The recurrence rate of the two groups was statistically analyzed.Results The average operation time of the observation group was significantly shorter than that of the control group,and the scar size was significantly smaller than that of the control group (P＜0.05).The deformity rate of the observation group was 0％,significantly lower than that of the control group (11.6％).The satisfaction rate was 97.7％ in the observation group,significantly higher than that of the control group (83.7％,P＜0.05).The postoperative complication rate was 4.7％ in the observation group,significantly lower than that of the control group (18.6％,P＜0.05).There was no recurrence in the two groups during 6 months of follow-up.Conclusion The application of single breast operation Mammotome treatment for benign breast tumor has the advantages of simple operation,shorter operation time,less intraoperative blood loss and surgical scars.It also can reduce the postoperative complications,keep breast shape,reduce the recurrence rate,so as to improve the patient satisfaction.

Objective To discuss the impact of group psychology guidance combined with conductive education on social anxiety of children with primary nephrotic syndrome. Methods A total of 60 children with primary nephrotic syndrome were selected, and divided into research group ( 30 cases ) and control group ( 30 cases ) according to the sequence of admission. The patients of two groups were given treatment of metacortandracin. The patients of control group received routine health education while the patients of research group underwent conductive education who was used social anxiety scale for children to evaluate the children anxiety level on the time of before treatment ( T1 ) , induced remission ( T2 ) , alternate-day-treated metacortandracin 1 mg/(kg.d)(T3), alternate-day-treated metacortandracin 0.5 mg/(kg.d)(T4), and the anxiety level of two groups were compared at different time point.Results There were significant differences on anxiety level of 4 time points in two groups ( P<0.01);the anxiety level of T2, T3, T4 in two group were higher than anxiety level of T1 ( P<0.05) . The anxiety level of T1, T2, T3, T4 in research group were lower than that of control group (P<0.05).Conclusions Long time used glucocorticoid can lead to the increasing of social anxiety levels in the treatment of children with nephrotic syndrome, but group psychology guidance combined with conductive education can effectively relieve the anxiety of children.
