ABSTRACT
Based on the virtual simulation of "digital embryo" in the digital teaching platform for medical morphology, this study constructs the course resources of human embryology by integrating the contents of the course, recording micro-videos, formulating course guides, and analyzing clinical cases, then implements the blended teaching model of pre-class preview, in-class discussion, and after-class expansion, and establishes a course evaluation system combining formative assessment and end-of-course assessment. Comparison of assessment scores and satisfaction questionnaire between traditional off-line teaching and blended teaching showed a significant improvement in total score, and more than 5% of the students reported a significant reduction in the difficulty of the course, while the degree of satisfaction with the course was increased by 11%. This suggests that the establishment of the blended teaching model of human embryology meets the requirements for personalized and diversified learning among students, realizes the diversity of teaching methods and teaching evaluation, and improves the quality of teaching.
ABSTRACT
Objective:To explore the role of one-to-one teaching led by international enterostomal therapist (ET) in the standardized training of wound stoma in gastrointestinal surgery.Methods:A total of 36 interns who underwent standardized training in the Gastrointestinal Surgery Department of The First Affiliated Hospital of Kangda College of Nanjing Medical University from July 2019 to January 2020 were selected as the control group, and the traditional teaching was adopted. Other 38 interns who were trained from May 2020 to October 2020 wre grouped into research group, and ET-led one-to-one teaching was adopted. The scores of theoretical knowledge and practical operation skills of gastrointestinal surgery wound stoma were compared between the two groups after the training, and the scores of case analysis, problem analysis and solving, knowledge application and comprehensive ability before and after the training were compared. Besides, satisfaction with methods and teaching effectiveness was compared. SPSS 25.0 was used for t test and chi-square test. Results:The clinical theoretical knowledge [(93.45±5.28) vs. (90.11±6.39)] and practical operation skills assessment scores [(92.25±6.18) vs. (89.13±5.36)] of the research group were all significantly higher than those of the control group after training ( P<0.05); the scores of case analysis ability, problem analysis and solving ability, knowledge application ability, and comprehensive ability of the two groups after the training were significantly higher than those before the training ( P<0.05), and the above scores in the research group were all higher than those in the control group ( P<0.05); the satisfaction of the interns in the study group with teaching methods and teaching effects was higher than that in the control group ( P<0.05). Conclusion:Applying ET-led one-to-one teaching to the wound and stoma teaching of gastrointestinal surgery residents can significantly improve their assessment performance, teaching satisfaction, and the teaching effect, and improve their case analysis ability, problem analysis and solving ability, knowledge application ability, and comprehensive ability.

ABSTRACT
Objective:To investigate the distribution and influencing factors of the ocular biological parameters related to refractive development in school-age children.Methods:A cross-sectional study was performed.A total of 1 091 children aged 6-12 years old from July, 2017 to August, 2018, resident in downtown of Zhenjiang were enrolled in this study.The corneal radius of curvature (CR) and axial length/corneal radius of curvature ratio (AL/CR) were calculated after AL and corneal curvature (K) were measured by IOL Master.After pupillary dilatation with 0.5% tropicamide, cycloplegic retinoscopy was performed to identify refractive status.According to the spherical equivalent refraction (SER), all right eyes were classified into myopia, hyperopia and emmetropia.The comparison of the above parameters between different genders, as well as among different age groups and different refractive status groups were determined while the relative factors of the biological parameters and refractive status were analyzed by multivariate regression analysis.The study protocol was approved by the Ethics Committee of Affiliated People's Hospital of Jiangsu University (No.K-20190153-W).Results:There were statistical differences in AL, SER and AL/CR value among different age groups ( F=32.34, P<0.01; F=33.69, P<0.01; F=2.19, P=0.04), which showed that refractive status shifted to myopia as well as AL and AL/CR value were increased with age.Compared with the girls, the boys had significantly longer AL, greater CR, greater AL/CR value, and smaller K ( t=7.58, P<0.01; t=-7.48, P<0.01; t=-8.08, P<0.01; t=-2.14, P=0.03). There were statistical differences in AL and AL/CR value among different refractive status groups ( F=192.68, P<0.01; F=143.15, P<0.01). The myopia group had longer AL and greater AL/CR value than the other two groups.Children whose parents were not myopic and children who had outdoor activities more than 14 hours per week and did homework less than 20 hours per week and children who slept more than 9 hours per day had shorter AL, smaller AL/CR value, and were more inclined to hyperopia or emmetropia.The results of multivariate regression analysis suggested that children aged from 6-12 years old with older age, female, increased height, parental myopia, and more time in homework or less time in outdoor activities per week may be more likely to have myopia, and longer AL or bigger AL/CR value was correlated with older age, male, greater body mass index (BMI), increased height, myopia conditions of parents, more time of doing homework, and less time in outdoor activities. Conclusions:The SER shifts to myopia with age in 6 to 12-year-old school-age children in the downtown of Zhenjiang.And there are significant differences in AL, CR and AL/CR value between boys and girls.Female, older age, increased height, more time in homework, less time in outdoor activities, and parental myopia are associated with more negative SER.

ABSTRACT
Objective To investigate the relationship between the plasma NT-proBNP level and the severity of acute asthmatic attack,and to provide a reference for the assessment of the severity of asthma and the prognosis of patients with acute asthmatic attack. Methods A total of 103 adult patients with mild,moderate,severe,and very severe acute asthmatic attack were enrolled in this study. The difference of plasma NT-proBNP level among groups,and the correlation between plasma NT-proBNP level and APACHE II score(Acute Physiology and Chron-ic Health Evaluation)were investigated.The correlation between plasma NT-proBNP level and Peak Expiratory Flow (PEF)was also studied in each group. Results There was significant difference in plasma NT-proBNP among groups(P < 0.05). Plasma NT-proBNP and APACHE II score was positive correlated(R = 0.767 1,P < 0.05). However,plasma NT-proBNP was negatively correlated with PEF(R =-0.709 7,P < 0.05). Conclusion NT-proBNP can be used as one of the indexes to evaluate the severity of acute asthmatic attack.
ABSTRACT
Background Retinitis pigmeutosa (RP) is a progressive inheritance disease.It is characterized by highly genetical and phenotypical heterogeneity.With the rapid development of genomics,new methods are applied to the genetic screening of RP.Objective This study was to characterize the clinical features of a Chinese family with autosomal RP and to screen the candidate genes.Methods Twelve members from this family were included in the study.All participants underwent complete ophthalmologic examinations.Targeted-capture next generation sequencing (NGS) based molecular genetic analysis was performed on two patients of this RP family(Ⅱ5,Ⅱ 7).The DNA sample from the two patients was separately sequenced using custom capture gene chip,which includes 59 retinal disease genes.The sequencing results were analyzed by bioinformatics technology.Identified variations were verified in the rest family members by PCR and Sanger sequencing.This study was approved by Ethic Committee of West China Hospital,and informed consent was obtained from the subjects.Results Four members of this family were diagnosed as RP,and the rest were asymptomatic.Missense mutation (c.3065T＞C,p.Phe1022Ser) in USH2A and missense mutation (c.1699G＞A,p.Ala1319Gly) in PDE6A were found in two patients (Ⅱ 5 and Ⅱ7).The variants were not co-segregated with the phenotype of this family.The causative mutation was not found by the targeted-capture NGS based eye disease chip,but it ruled out a large number of candidate genes for RP.Conclusions Our study suggests that targeted-capture NGS based eye disease chip can quickly detect mutations in known RP genes.It can be a new applicable and efficient method for molecular genetic analysis of ocular disease.
ABSTRACT
Glaucoma is the most common cause of irreversible blindness worldwide.The major performances of glaucoma optic neuropathy are progressive loss of retinal ganglion cells (RGCs),specific visual field defect and optic atrophy induced by elevated intraocular pressure.Glaucoma primarily includes primary open angle glaucoma (POAG),chronic angle-closure glaucoma (CACG) and exfoliation glaucoma (XFG).Recent studies showed that genetic factor and environmental factor participate in the pathogenesis of glaucoma,and the contributions of genetic factor to glaucoma are widely concerned,and some disease-causing gene and their pathogenic mechanisms are sequentially announced.A comprehensive discussion of the advances in molecular genetics of glaucoma is included in this paper.
ABSTRACT
Objective:To compare the efficacy of penehyclidine hydrochloride and atropine in the prevention of catheter related bladder discomfort(CRBD) in patients undergoing gynecology laparoscopic surgery.Method;Eighty ASA classⅠorⅡpatients undergoing elective gynecology laparoscopic surgery were randomly assigned into 2 groups of P and A with 40 cases each.Fifteen minutes before the anesthesia induction,penehyclidine hydrochloride 0.5 mg and atropine 0.25 mg were administered in Group P and Group A,respectively.After the induction of anesthesia,patients were catherized with a 14 Fr Foley's catheter.HR,bladder discomfort,Ramsay Sedative Score(RSS) and side reactions were recorded at 0 h,0.5 h,1 h and 6 h after the end of surgery in the post-anaesthesia care unit(PACU).The severity of bladder discomfort was graded as mild,moderate and severe.Result:The total incidence rate of CRBD in Group P was apparently lower than that in Group A(P0.05).The incidence rate of CRBD of Group P was apparently lower than that in Group A at 6 h after the end of surgery(P0.05).Conclusion:The application of enehyclidine hydrochloride before anesthesia induction provides a better prophylactic effect of CRBD than that of atropine but with a higher incidence rate of dry mouth.
