Objective To investigate the present situation of the core competencies of nurses and patient's safety culture cognition in level two class A hospital,and analyze the correlation of the core competence and patient safety culture cognition,so as to offer a proposal to improve the core competence and patient's safety culture cognition.Methods A total of 342 clinical nurses in Hu'nan province from six level two class A hospitals from August to September 2016 by convenient nonprobability sample method,using the general information questionnaire,hospital core competence scale and registered nurses'perception of patient safety culture assessment questionnaire.Results The mean scores of 342 nurses' (from level two class A hospitals) the core competence and the patient's safety culture of nurses' cognition were (2.51±0.69) points and (4.06±0.37) points, which both were at the medium level. The total score of nurses' competency was positively correlated to the total score of patient's safety culture cognition (r=0.395,P<0.01).ConclusionsHospitals should improve construction of medical organization atmosphere,and strengthen the communication and cooperation between higher and lower levels,and promote the team cooperation ability,so as to facilitate the nurses' recognition level for patient's safety culture,reduce adverse event,and provide a better nursing quality.

Objective: To investigate the prevalence of anemia among students aged 6-15 years old participated in the Nutrition Improvement Program for Rural Compulsory Education Program in 2012-2021 in Hunan Province, and to explore associated factors. Methods: A cluster random sampling method was used. The survey was conducted among compulsory education students who came from counties in Hunan Province where nutrition improvement plan and key surveillance were carried out. Height and weight were measured, hemoglobin, dietary habits and health knowledge were collected. Results: Since the implementation of nutrition improvement plan in 2012, the anemia rate decreased from 12.8% to 9.3%, the average hemoglobin content decreased from 133.9 g/L to 130.0 g/L. The proportion of students eating meat every day increased from 20.4% to 47.3%. Students eating three or more servings of table tennis ball size of meal increased from 21.4% to 47.3%. The proportion of students eating more than three kinds of vegetables per day was 39.1% in 2016 and 32.6% in 2019, and less than 30% in other years. The proportion of students eating three or more servings of table tennis ball size of vegetables increased from 19.5% to 39.6%, and the proportion of students eating snack less than once a day increased from 13.1% to 76.9%. The proportion of students drinking beverages less than once a day increased from 36.5% to 90.7%. Girls, older than 12 years, not eating meat every day, and who eat less than 1 serving of table tennis ball size of meat, eat less than 3 servings of table tennis ball size of vegetables and fruit at one time, and who eat less than 3 kinds of vegetables every day, and those who grow slowly had higher risk of anemia. Potential factors of anemia in students varied by survey year. Conclusion The implementation of the compulsory education has improved the nutritional status of compulsory education students in rural areas of Hunan Province, but anemia still occurs. Potential factors associated with childhood anemia are changing. Child health literacy education should adapt to the changing social and economic enviornment, as well as lifestyles. Targeted and appropriate nutritional education and intervention are greatly needed.

Objective: To investigate the feasibility of repairing soft tissue defects of extremities with the perforator flap based on the first perforating artery of profunda artery. Methods: From January 2015 to December 2018, 9 patients with soft tissue defects of extremities were treated in the Department of Burns and Plastic Surgery, Affiliated Hospital of Zunyi Medical University. 5 males and 4 females; aged 29-48 years, average 36 years old. The causes of injury were traffic accident injury (4 cases), heavy object crush injury (3 cases) and mechanical injury (2 cases). There were 3 cases of soft tissue defect of upper limb, 6 cases of soft tissue defect of lower extremity, 2 cases of tendon and nerve rupture, 2 cases of fracture, 1 case of tendon and 1 case of bone exposure. All soft tissue defects were repaired with the perforator flap based on the first perforating artery of Profunda artery. After debridement, The range of soft tissue defect was 10 cm×5 cm-16 cm×10 cm. The intraoperative flap area was 12 cm×6 cm-18 cm×11 cm. The vascular anastomosis was performed in the area, the flap covered the wound surface and the donor site directly pulled the suture or grafted skin. Results: All flaps survived completely and there were no complications such as vascular crisis. Follow-ups were performed in various forms for 6 to 12 months. These flaps were satisfactory in appearance and function and had a good texture. Conclusions The perforator flap based on the first perforating artery of profunda artery can repair the defects of the limbs in the soft group. The donor site of the flap is hidden, the amount of tissue available is relatively large and the repair effect is good.
