Application Effect of Plan-do-check Action Cycle Nursing Protocol on Improving the Accuracy of Urine Specimen Collection in Newborn Female Infants.

Background: The effect of traditional disposable infant urine collectors is not ideal for female newborns. Due to the poor adhesion of the traditional urine collection bag, it does not meet the physiological and anatomical characteristics of female newborns. Therefore, it is necessary to adopt effective nursing in urine specimen collection in newborn female infants. Objective: To explore the effect of plan-do-check action cycle nursing protocol on improving the accuracy of urine specimen collection in newborn female infants. Design: This was a randomized controlled study. Setting: This study was carried out in the Department of Pediatrics, Strategic Support Force Medical Center. Participants: A total of 120 female newborns admitted to our hospital from January 2021 to June 2022 were selected and divided into a control group and a study group, with 60 cases in each group. Interventions: The control group collected urine samples by routine methods, which used the traditional disposable urine bag collection method. The study group collected urine samples using the plan-do-check action cycle nursing mode. Primary Outcome Measures: (1) success rate of urine collection, collection times, and sample contamination rate (2) cleanliness of the vaginal opening (3) satisfaction of urine collection (4) retention time of urine samples and (5) urine pondus hydrogenii values. Results: Compared to the control group, the success rate of urine collection in the study group was higher, the collection times and specimen contamination rate were significantly lower, the time for collecting urine samples in the study group was shorter, the cleanliness of female vaginal opening in the study group was significantly better, the proportion of female urine pondus hydrogenii 6-7 in the study group was significantly higher (all P < .05). Conclusion: The application of the plan-do-check action cycle management mode in the urine samples of newborn female infants can not only effectively improve the success rate of collection but also improve the cleanliness of the vaginal mouth and make the test results more accurate.

Preparation and in vitro anticancer activity of oxymatrine mixed micellar nanoparticles.

The aim of this study was to prepare oxymatrine (OMT) mixed micellar nanoparticles to delay release of the drug and enhance its cytotoxicity against cancer cells. A co-solvent evaporation method using lipoid E80, lipoid S75, MPEG-PLA and Poloxamer 188 was chosen to prepare the OMT formulation, and its release characteristics, cytotoxic activity in vitro and physical characteristics were evaluated. The results showed that OMT mixed micellar nanoparticles have sustained release and cytotoxic activity in vitro to the SMMC-7721 cell line.

Peripheral dentinogenic ghost cell tumor of the ethmoid sinus: A case report.

RATIONALE: The dentinogenic ghost cell tumor (DGCT), a locally invasive benign neoplasm, is one of the rarest odontogenic tumors, usually developing in the maxilla or mandible. It can be classified into 2 types: intraosseous (central) and extraosseous (peripheral). Here, we describe the first case of a peripheral DGCT located in the ethmoid sinus. PATIENT CONCERNS: An 8-year-old boy presented to our department with a longer than 7-month history of nasal obstruction, purulent secretion, and reduction in sense of smell in the right nasal cavity. DIAGNOSIS: The patient was diagnosed with peripheral DGCT of the ethmoid sinus based on computed tomography scan and pathology. INTERVENTIONS: Functional endoscopic sinus surgery was performed. OUTCOMES: With 2 years of follow-up, there was no evidence of recurrence. LESSONS: Peripheral DGCT can occur in the paranasal sinus and the need to consider this entity as a possible diagnosis by the clinicians.
