Objective To identify the core interventions preliminarily performed by pediatric nurses for hospitalized children. Methods Based on Nursing Interventions Classification (NIC), the data of survey related to the factors of representation and frequency derived from the definition of Core Nursing Interventions were collected from 59 pediatric senior nurses above the 3rd clinical ladder, working in one of Shanghai university affiliated and tertiary children hospitals. The data was analyzed by L type of Metric Diagram. The intervention with product of two factors above 12 was selected as the core intervention. Results A total of 109 interventions were selected as core interventions on pediatric nursing from 497 interventions of NIC. The top 3 domains in quantity of interventions were physiological complex domain (36 items), physiological basic domain (26 items) and health system domain (19 items). The domain with the highest score (16.79 ± 3.42) was safety domain, followed by physiological complex domain (16.19 ± 2.98), while domain with the lowest score (13.62±2.05) was family domain. Conclusions The initial and systematic pediatric nursing core interventions were identified based on NIC and definition of core intervention. Part of core interventions reflects the characteristics of pediatric nursing practice, but more is requested to reflect the pediatric-specific care related to family-center and age-appropriated concepts. Some of inefficient interventions remind nursing administers further reflect thinking, especially on human resource management.

0.05). Conclusion The procedure of double-tunnel with double-bundle for reconstruction of posterior cruciate ligament (PCL) under arthroscopy can better improve the knee stability at the different flexion degree, and the QT-B is an optimal graft for the double-tunnel reconstruction.

Crohn's disease (CD) is a chronic nonspecific inflammatory disease.CD can affect any location in the digestive tract,and it also affect other organs,including the eyes,skin,liver and joints,which are termed extraintestinal manifestations (EIMs).The cutaneous manifestations of CD are common and occur in about one-third of patients.EIMs of CD have been divided into 3 categories.(1) Specific lesion,cutaneous manifestations of CD were the same as histopathologic findings of underlying gastrointestinal lesion.(2) Reactive lesion,it was also inflammatory lesion which was usually accompanied by underlying gastrointestinal disease while inflammatory injury was different from histopathologic findings of gastrointestinal lesion.(3) Associated lesion,it was caused by sequelae of human leucocyte antigen and chronic inflammation.In the current era of ever-expanding therapeutic options for CD,some investigators have proposed a fourth category of EIMs,namely those that are therapy-related lesion.The therapy-related lesion is closely related to disease-associated conditions in light of certain skin findings,and there is potential overlap between them.

Objective:To analyze the clinical applicability of the sixth edition of nursing measures classification in children's general surgery, to provide a basis for standardizing clinical nursing terms and to promote the clinical use of standardized terminology of nursing measures.Methods:The research method of this study was mapping method. The electronic nursing records of the general surgery of Shanghai Children′s Medical Center Affiliated to Shanghai Jiaotong University School of Medicine from October 1st to December 31st, 2018, including the records of care records for free entry and the records of nursing measures related to medical orders were selected. The degree of matching between electronic care records and classification of nursing measures (sixth edition of nursing measures classification) was compared with conceptual consistency. Difficulties and time-consuming analysis of the characteristics of the standardized care measures obtained by matching.Results:A total of 4 560 independent electronic care records mapped 86 treatments in seven areas. Among them, 98.84% (4 507/4 560) of the nursing records were completely matched with the nursing measures, 0.83% (38/4 560) of the nursing records were partially matched with the nursing measures, and 0.33% (15/4 560) of the nursing records did not match the nursing measures. Difficulty and time-consuming were expressed as standard deviation, which were 2.20±0.45 and 2.03±1.25 respectively.Conclusions:The classification of nursing measures can be used to describe the daily behavioral activities of the children's general surgery nurses, and can also solve the standardization problem of the nursing records in the presentation, and is suitable as a standardized nursing language for the nursing records of children's general surgery.

Objective To investigate the efficacy of treatment on malignant intracranial gliomas with the chemotherapy of intracerebral implantation of 5-Fu biodegradable polymers combined with radiotherapy of interstitial implantation of 125Ⅰ after microsurgery resection. Methods Sixty-five patients with malignant intracranial gliomas who had underwent craniotomy microsurgical resection were intraoperatively implanted in the tumor bed around with 5-Fu biodegradable polymers and 125Ⅰ seeds. After first implantation (3 months to 1 year), stereotactic guided implantation was carried out 1 or 2 times again. The patients were followed up for 6-36 months to observe the efficacy, edema and adverse reactions, compared with follow-up of 40 patients with malignant intracranial gliomas treated by conventional radiotherapy and chemotherapy after microsurgical total resection. Results Within 1 week after the implantation the patients had headache significantly, WBC of cerebrospinal fluid was increased to some degrees, and edema was obvious compared with surgery alone. All patients were treated and discharged. Forty-four patients were completely followed-up and the survival period was significantly longer. Within 6 months, 1 year, 2 years and 3 years, there were 4 cases (9.1 %) of recurrence and no case of death, 14 cases (31.8 %) of recurrence and no case of death, 20 cases (45.5 %) of recurrence and 12 cases (27.6 %) of death and 29 cases (65.9 %) of recurrence and 20 cases(45.5 %) of death, respectively. No obviously adverse reactions were found and the quality of life was significantly improved. Conclusion Microsurgical total resection is the key of the treatment. It is an alternative treatment of human malignant gliomas in the safe and effective way that the local chemotherapy of intracerebral implantation of 5-Fu biodegradable polymers combined with local sensitivity radiotherapy of interstitial implantation of 125Ⅰ after microsurgical resection.

The association rate constant and dissociation rate constant are important parameters of the drug-cyclodextrin supermolecule systems, which determine the dissociation of drugs from the complex and the further in vivo absorption of drugs. However, the current studies of drug-cyclodextrin interactions mostly focus on the thermodynamic parameter of equilibrium constants (K). In this paper, a method based on quantitative high performance affinity chromatography coupled with mass spectrometry was developed to determine the apparent dissociation rate constant (k(off,app)) of drug-cyclodextrin supermolecule systems. This method was employed to measure the k(off,app) of meloxicam and acetaminophen. Firstly, chromatographic peaks of drugs and non-retained solute (uracil) on β-cyclodextrin column at different flow rates were acquired, and the retention time and variance values were obtained via the fitting the peaks. Then, the plate heights of drugs (H(R)) and uracil (H(M,C)) were calculated. The plate height of theoretical non-retained solute (H(M,T)) was calculated based on the differences of diffusion coefficient and the stagnant mobile phase mass transfer between drugs and uracil. Finally, the k(off,app) was calculated from the slope of the regression equation between (H(R)-H(M,T)) and uk/(1+k)2, (0.13 ± 0.00) s(-1) and (4.83 ± 0.10) s(-1) for meloxicam and acetaminophen (control drug), respectively. In addition, the apparent association rate constant (k(on,app)) was also calculated through the product of K (12.53 L x mol(-1)) and k(off,app). In summary, it has been proved that the method established in our study was simple, efficiently fast and reproducible for investigation on the kinetics of drug-cyclodextrin interactions.
