Objective To study and contruct competency characteristic evaluation models of nursing supervisors in secondly hospitals.Methods Using the matron semi-structured interviews,literature review,questionnaire survey and expert questionnaires to discuss the competency of nursing supervisors in secodary hospitals.Results We found that the competency model of nursing supervisors in secondary hospitals could better reflect the competency of nursing supervisors.The model had 16 competencies which included knewleage skills.management and individual characters.Conclusions Through the study of the model of competency nursing supervisors in secondary hospitals,we form a set of standard for nursing supervisor selection based on their competency.The standard can help to select the most suited nursing supervisors who have great potentials.

OBJECTIVE: To investigate the effects of compound preparation of Cordyceps sinensis and Tripterygium hypoglaucum (CSTHC) on survival time of grafted pigskin after allogeneic transplantation and its mechanism. METHODS: The pigskin was treated with CSTHC solution before allogeneic transplantation, and CSTHC ointment was applied for external use on the grafted pigskin after skin transplantation. Cyclosporine A (CsA) and normal saline were served as control. The survival time, the appearance and the histomorphological changes of the grafted pigskin were observed. The histomorphological changes of testicles in pigs were also examined. The CD4 and CD8 expressions in the grafted pigskins were measured by immunohistochemical method. The white blood cell count in peripheral blood and the liver and renal functions were also examined. RESULTS: The survival time of the grafted pigskin in the CSTHC-treated group was (28.50+/-3.26)d, which was much longer as compared with (10.60+/-1.52)d in the untreated group (P<0.01). The survival time of the grafted pigskin in the CsA-treated group was (28.33+/-3.50)d, and there was no remarkable difference in the survival time of the grafted pigskin between the CsA-treated group and the CSTHC-treated group. The expressions of CD4 and CD8 were lower in the CSTHC-treated group than those in the untreated group on the 7th and 14th day after skin graft (P<0.05), while there was no significant difference in the indices between the CSTHC-treated group and the CsA-treated group. The WBC count was higher in the untreated group than that in the CSTHC-treated group or CsA-treated group on the 7th day after skin graft (P<0.05). CONCLUSION: CSTHC can prolong the survival time of allogeneic grafted pigskin. Its mechanism of inhibiting the immunological rejection may relate to decreasing the expressions of CD4(+) and CD8(+) in the grafted pigskin and reducing the local inflammatory reaction.

The concept and significance of readiness for hospital discharge, measuring tools, application status, shortcomings and prospects of readiness for hospital discharge among patients with chronic diseases were reviewed in this article, with attempts to draw more attention to the readiness for hospital discharge among patients with chronic diseases in clinical practice and provide theoretical basis for forming the intervention plan suitable for China.

Objective To understand the hospital discharge readiness and discharge instruction quality in chronic disease patients and to analyze the correlation between them. Methods Totals of 602 chronic disease patients of related departments from 7 ClassⅢGrade A hospitals in Shanghai were selected by convenience sampling. All of them were investigated with the general information questionnaire, Readiness for Hospital Discharge Scale (RHDS) and Quality of Discharge Teaching Scale (QDTS), and their data were analyzed. Results Among those patients, the scores of hospital discharge readiness and discharge instruction quality were (8.01±1.41) and (8.65±1.29) out of 10 respectively. The score of hospital discharge readiness had a positive correlation with the score of discharge instruction quality with a statistical difference (r=0.507, P＜ 0.01). Conclusions Hospital discharge readiness and discharge instruction quality of chronic disease patients are all in high levels and with a positive correlation. Nurses should enrich the content of discharge instruction to improve the quality of discharge instruction by appropriate instruction skills and to improve the hospital discharge readiness.

Objective:To analyze the clinical characteristics and endoscopic surgical procedures of the second branchial cleft cyst type Ⅳ in children.Methods:A retrospective review was conducted on 15 pediatric cases with type Ⅳ second branchial cleft cysts treated at the Beijing Children′s Hospital affiliated with Capital Medical University and Henan Children′s Hospital from September 2019 to November 2023. All patients underwent excision via a two-person, three-hand endoscopic transoral approach. The cohort included 12 males and 3 females, with an age range of 10 months to 10 years and 5 months, and a median age of (59.20±32.05) months. The clinical data of initial symptoms, sides, imaging features, treatment methods, complications, length of hospital stay, prognosis and outcome were recorded and analyzed. SPSS 22.0 software was used for statistical analysis.Results:Of the 15 children, 13 cases presented with snoring as the primary symptom, 1 case with dysphagia, and 1 case was asymptomatic and was found unintentionally. The mean disease duration was (6.74±9.05) months (range, from 3 days-2 years). MRI revealed cystic lesions on the right side in 12 cases and on the left side in 3 cases, characterized by uniform long T2 signal, equal T1 or short T1 signal. The cysts appeared dumbbell-shaped in 10 cases with the pharyngeal constrictor muscle as the waist, the posterior outside of the mass was adjacent to the internal carotid artery. The remaining 5 cases showed an isolated cyst located inside the pharyngeal constrictor muscle. The intraoperative MRI findings were consistent. Partial cystectomy was performed in 10 cases near the internal carotid artery, leaving only the portion with a clear arterial pulse intact. Five cases with isolated cysts on the medial side of the pharyngeal constrictor muscle were totally removed. The average length of hospital stay was (4.53±0.52) days (4-5 days). All patients were followed up for 7-56 months [median (30±15.12) months] with no recurrence of symptoms observed.Conclusions:The second branchial cleft cyst type Ⅳ in children is characterized by prominent pharyngeal cystic mass, with snoring as a predominant initial symptom, MRI provides excellent diagnostic value. The two-person, third-hand endoscopic transoral approach for cyst excision is feasible, safe, and offers the benefits of minimal invasiveness and reduced hospitalization time.

Severe acute pancreatitis-associated acute lung injury (SAP-ALI) is a serious disease associated with high mortality. Emodin has been applied to alleviate SAP-ALI; however, the mechanism remains unclear. We report that the therapeutic role of emodin in attenuating SAP-ALI is partly dependent on an exosomal mechanism. SAP rats had increased levels of plasma exosomes with altered protein contents compared to the sham rats. These infused plasma exosomes tended to accumulate in the lungs and promoted the hyper-activation of alveolar macrophages and inflammatory damage. Conversely, emodin treatment decreased the plasma/pancreatic exosome levels in the SAP rats. Emodin-primed exosomes showed less pro-inflammatory effects in alveolar macrophages and lung tissues than SAP exosomes. In detail, emodin-primed exosomes suppressed the NF-κB pathway to reduce the activation of alveolar macrophage and ameliorate lung inflammation by regulating PPARγ pathway, while these effects were amplified/abolished by PPARγ agonist/antagonist. Blockage of pancreatic acinar cell exosome biogenesis also exhibited suppression of alveolar macrophage activation and reduction of lung inflammation. This study suggests a vital role of exosomes in participating inflammation-associated organ-injury, and indicates emodin can attenuate SAP-ALI by reducing the pancreatic exosome-mediated alveolar macrophage activation.
