Objective To evaluate the clinical results of arthroscopic repair of massive rotator cuff tear. Methods The study involved 16 patients with massive rotator cuff tears treated arthroscopically from September 2007 to June 2009. There were 6 males and 11 females at average age 61.5 years (45-75 years). The rotator cuff tears was repaired with arthroscopic double-row reconstruction. The range of motion, pain, strength of flexed elevation and function evaluation score were all recorded before operation and at final follow-up. The results were evaluated by t test and compared according to age and course of disease. Results All patients were healed without complications and the outcome was improved significantly ( P < 0.01 ). The mean VAS score was improved from preoperative 5.6 to postoperative 1.7,the average forward flexion from 69. 1°to 151.2°, the average external rotation from 14.7° to 32.2°, and internal rotation from L1 level to T10, the mean Constant-Murle from 39 to 85, the mean UCLA from 10.4 to 28, the mean SST from 2.8 to 8.8 and the strength of flexed elevation from 10.7% of normal side to 65.0%. Compared with preoperation, there was statistical difference in aspects of pain, range of motion, muscle strength and function in postoperation (P < 0.01 ). Conclusion Arthroscopic doublerow fixation can attain satisfactory results in repair of massive rotator cuff tear.

BACKGROUND: Changes in the center of body weight during standing reflects the structure, function and muscles of the lower limbs and even the whole body. The relationship between standing posture control and foot type, balance ability, and muscle activation is rarely reported. OBJECTIVE: To investigate the effects of natural, lean forward and lean backward standing on foot arch, body balance and muscle activation. METHODS: Fifteen subjects without foot lesions and diseases related to foot function were selected. Three-dimensional foot scanner was used to test and analyze the foot arch in three standing postures. BTS FREEMG 300 surface electromyography tester and balance tester were used to test and analyze the maximum root mean square of muscle and two balance ability indexes (envelope area and average velocity of center of gravity) in three standing postures. RESULTS AND CONCLUSION: (1) For height index of foot arch: there was significant difference between natural standing and forward standing (P ＜ 0.05). There was significant difference between natural standing and backward standing (P ＜ 0.05), but there was no significant difference between forward standing and backward standing (P＞ 0.05). (2) The degree of muscle activation was as follows: when standing naturally, the medial peroneal muscles＞ erector muscles＞ rectus abdominis＞ gluteus medius＞ biceps femoris＞ external oblique femoris＞ anterior tibial muscle＞ rectus femoris muscle＞ gluteus maximus muscle. During forward standing: the medial of the peroneal muscle＞ medius gluteus＞ vertical ridge＞ long head of biceps femoris＞ anterior tibial muscle＞ rectus abdominis muscle＞ gluteus maximus. During backward standing: the obliquus externus femur＞ rectus femoris＞ long head of biceps femoris＞ erector spinae＞ musculus rectus abdominis＞ the medial of the peroneal muscle＞ gluteus medius＞ gluteus maximus. (3) Balance: there was no significant difference between natural standing and forward standing (P＞ 0.05); there was significant difference between natural standing and backward standing (P ＜ 0.05), but there was no significant difference between forward standing and backward standing (P＞ 0.05). (4) In summary, it is easy to maintain body stability at low muscle activation intensity when the human body is standing naturally. During the body backward standing, the muscle activation intensity is highest due to instability. When the center of gravity moves forward and backward, the contralateral muscle is mainly activated. The arch of the foot rises when it leans forward and backward. The slight anterior and posterior movements of the center of gravity in the standing posture can lead to changes in muscle activation degree and balance control.

Objective:To explore the effect of knowledge-clinical-sharing (KCS) model in humanistic care training of pediatric nurses.Methods:A total of 182 specialist nurses who were trained in Hunan Children's Hospital from June 2019 to December 2019 were selected as the research objects. Among them, 102 specialist nurses from June 2019 to August 2019 were selected as the control group, and 80 specialist nurses from September 2019 to December 2019 were selected as the intervention group. The Jefferson empathy scale was used to compare the effect of humanistic training before and after the implementation. SPSS 22.0 statistical software was used, measurement data were test by F-test and t-test, and the counting data were analyzed by Chi-square test. Results:After the implementation of humanistic care training based on KCS model, the empathy ability score of the intervention group was higher than that of the control group [(80.23±5.33) vs. (78.14±4.37)], and the difference was statistically significant ( P < 0.01). There was no significant difference between neonatal and pediatric specialist nurses before and after the training. Conclusion:The phased humanistic training based on KCS model can improve the empathy ability of pediatric nurses and enhance their confidence in the clinical implementation of humanistic care. However, the humanistic training mode of pediatric nurses should be improved according to the hospital's own situation, so as to adapt to the development of nursing industry.

Objective:To investigate the knowledge and practice of intravenous therapy by pediatric nurses in a province, and analyze the factors influencing the knowledge level of pediatric nurses.Methods:Convenience sampling was used to organize 695 pediatric nurses participated in the academic conference on intravenous therapy safety in a province in May 2019. The self-designed Nursing Practice Standards for Intravenous Therapy Knowledge and Practice Questionnaire was used to investigate. A total of 698 questionnaires were collected including 695 valid questionnaires. Results:Among 695 pediatric nurses, the score of knowledge of intravenous therapy was (51.74±12.90) . There were statistical differences in the score of knowledge of intravenous therapy among pediatric nurses with different education levels, professional titles, positions, ages and working years ( P<0.05) . Multiple linear regression analysis showed that the professional title and position were influencing factors of intravenous therapy knowledge of pediatric nurses in a province ( P<0.05) . The practice standard for intravenous therapy was generally good, but there were still cases of poor education and communication, accounting for 1.73% (12/695) and 2.30% (16/695) respectively. Conclusions:Pediatric nurses in a province lack knowledge of intravenous therapy and are affected by multiple factors. Nursing managers should regularly carry out relevant training for pediatric nurses, especially nurses with low seniority and low professional title. The training should focus on the safety of nursing staff, the assessment of patients' blood vessels and the protection of puncture sites, in order to improve the knowledge of pediatric nursing staff in intravenous therapy.

Quantitative analysis was carried out using Medical Literature King, Excel 2019 and SPSS 25.0.Results:The number of documents that met the requirements was 303, and the number of documents was on the rise. A total of 224 documents were published from 2013 to 2019, accounting for 73.93% of the total number of documents. Guangdong Province had the largest number of published documents, with 53 articles (17.49%) , followed by Jiangsu with 29 articles (9.57%) . The document fund support rate was 16.17% (49/303) , and the co-author rate was 64.03% (194/303) , and the author's collaboration was 1.96 (595/303) . Among the document types, the number of case-control studies was the largest, with 249 (82.18%) , and the second was review literature, with 32 (10.56%) . The contents of the document research were mainly feeding and growth and development, with 182 articles (60.07%) and 34 articles (11.22%) respectively. The evaluation indicators used were mainly oral feeding time, body weight, hospital stay and milk sucking volume.Conclusions:The overall number of the document is on the rise, and the research efforts continue to increase, but the quality of the document, fund support rate, and evidence-based strength still need to be improved, and the research content needs to be further expanded.

Objective:To construct an evaluation index system for health literacy of parents of children with Kawasaki disease, so as to provide a basis for accurately determining health literacy of parents of children with Kawasaki disease.Methods:A research team was established in September 2020. With the three dimensions of 66 Items of Chinese Citizens' Health Literacy as the basic framework, based on literature analysis and semi-structured interviews with 10 parents of children with Kawasaki disease were conducted, the primary evaluation indicators of health literacy of parents of children with Kawasaki disease was constructed. From October to December 2020, questionnaires were sent to 15 experts through email or Wechat for three rounds of Delphi expert consultation. And the evaluation indicators of health literacy of parents of children with Kawasaki disease were determined according to authority coefficient and Kendall's coordination coefficient. Results:The recovery rates of the three rounds of expert consultation questionnaires were all 100.00%, and the expert authority coefficients were 0.907, 0.913 and 0.920, respectively. In the third round of expert consultation, the Kendall's coordination coefficient of the coordination degree of general indexes, the first-level indexes and the second-level indexes were 0.376, 0.328 and 0.319 respectively (all P<0.01) . The final health literacy evaluation index system for parents of children with Kawasaki disease consisted of 3 first-level indicators and 34 second-level indicators. Conclusions:The established health literacy evaluation index system for parents of children with Kawasaki disease is scientific and reliable, which can provide an effective tool for nursing staff to accurately assess the health literacy of parents of children with Kawasaki disease.
