RESUMEN
【Objective】 To discuss the practice of emergency recruitment of blood donors through TikTok by shooting short videos, and evaluate the recruitment effect. 【Methods】 The completed short videos about blood donor emergency recruitment were released by major media official accounts on TikTok on New Year′s Day, May Day and National Day in 2022. Blood collection data within 10 days before and after the release were collected, and data within 7 days after the release were selected as the experimental group and the same period in last year as the control group to compare the blood collection units, donation frequency, gender and age of blood donors. 【Results】 The units of daily blood collection was the largest on day 1 after the release of TikTok short video, which was 3 times that of the previous day, and then decreased day by day, until to the same level as before the release on day 7. The daily blood collection, the proportion of first-time blood donors, donors aged 26 to 55 years old in the experimental group were all higher than those of the control group, but the proportion of blood donors aged 18 to 25 years old was lower than that of the control group. There was no significant difference in gender between the two groups. 【Conclusion】 Releasing short videos of blood donor emergency recruitment through TikTok, with fast dissemination and wild audience, can increase the blood inventory in a short time and is worthy of promotion.
RESUMEN
Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.
RESUMEN
Objective:To study the effect of micro-course teaching combined with teacher standardized patient combined with objective structured clinical examination (TSP/OSCE) on clinical practice teaching of pediatric nursing.Methods:Forty nurses who performed clinical practice in Pediatrics Department from February 2019 to July 2019 were selected as the control group, and traditional teaching was adopted in the group. In addition, 42 nurses who performed clinical practice in Pediatrics Department from August 2019 to January 2020 were selected as the research group, and the micro-course teaching combined with TSP/OSCE mode teaching was adopted in the group. Two groups of nurses' theoretical and practical skills assessment results were analyzed, and a questionnaire survey was conducted to assess nurses' satisfaction with the teaching of pediatric nursing clinical practice training mode. SPSS 22.0 was used for t test and chi-square test. Results:The research group nurses' theoretical and practical skills assessment scores were better than those of the control group, and the difference was statistically significant ( P=0.000).The nurses in the research group were more satisfied than those in the control group with such eight aspects as improving practical skills, emergency response capabilities, humanistic care and service capabilities, communication skills, and stimulating their interest in nursing learning. There were statistically significant differences ( P<0.05). Conclusion:The use of micro-teaching combined with TSP/OSCE mode in the clinical practice teaching of pediatric nursing can improve nurses' clinical practice ability and increase nurses' satisfaction in pediatric training.
RESUMEN
OBJECTIVE: This study aimed to analyze the bone anatomy of edentulous sites in the posterior maxillary by cone beam computed tomography (CBCT). METHODS: A total of 100 CBCT radiographs from patients with missing maxillary posterior teeth were obtained, resulting in a sample size of 217 edentulous sites. The width and height of edentulous were assessed by three-dimensional reconstruction. In addition, the angle A and morphology of the maxillary sinus walls were evaluated. RESULTS: The mean bone height was 9.53 mm, and the percentage of sites than 10 mm was 62.67% (136/217). The mean bone width was 9.30 mm, and the percentage of sites more than 6 mm was 91.71% (199/217). The bone height decreased from premolar to molar areas, but the opposite trend was observed in bone width. Regarding the morphology of the sinus floor, 64.52% exhibited an oblique configuration. In angle A, the group of less than 30° was 10.14%, 30°-60° was 42.40%, and greater than 60° was 47.47%. CONCLUSION: A high percentage of edentulous sites in the posterior maxillary requires sinus floor elevation to allow the placement of dental implants. Thus, the use of CBCT scans is recommended to evaluate the anatomical structure of the maxillary sinus for reasonable implant planning.
