Chinese Journal of Current Advances in General Surgery 2004;0(05):-
Objective:To investigate the expression and clinical significance of metastasis suppressor gene Kiss-1 and KAI-1 in colorectal cancer. Methods: In situ hybridization was used to detect and analyze the gene expression of Kiss-1 and KAI-1 in 61 cases of colorectal cancer and 20 cases of normal para cancer tissue. Results: In situ hybridization revealed that the positive expression rates of Kiss-1 and KAI-1 in colorectal cancer were significantly lower than those in normal para cancer tissue (P
2.Analysis of epidemiological features of food-borne diseases through active surveillance in Wenchang, Hainan Province from 2017 to 2021
Shanghai Journal of Preventive Medicine 2023;35(7):667-673
ObjectiveTo understand the epidemiological and etiological characteristics of food-borne diseases in Wenchang, Hainan Province, and to analyze the suspected food exposure sites and sources so as to provide scientific data for early prevention. MethodsThe data of food-borne disease cases, including basic information, time, population, region, suspected exposed food, etiology, etc., from the sentinel hospitals of the surveillance systems in Wenchang from 2017 to 2021 were statistically analyzed. ResultsA total of 2 219 food-borne disease cases were collected from 2017 to 2021. The male-to-female sex ratio was 1.2:1, and there was no significant statistical difference (χ2=5.732, P>0.05). Cases were mainly concentrated in children aged <7 years (43.26%), followed by 7 to 18 years (15.41%), 19 to 30 years (11.72%) and >60 years (11.36%), and there was a significant statistical difference (χ2=168.125, P<0.001). The highest number of cases were found in preschool children (36.05%), followed by students (17.49%) and farmers (16.18%). The peak incidence occurred from July to November (54.44%). The suspected exposure foods reported in the monitored cases were mainly vegetable foods (17.49%) and mixed foods (17.08%). The exposure sites were primarily households (76.30%) and catering services (13.56%). The positive rate of pathogens was 12.26% in 1085 tested samples, and there was no statistically significant difference in the annual detection rate (χ2=1.086, P>0.05). The main pathogens of food-borne pathogens were Salmonella (9.95%), followed by norovirus (2.03%) and rotavirus (0.28%). ConclusionThe surveillance of foodborne disease cases in Wenchang shows seasonal peak patterns according to population and pathogen epidemiological features. The main affected groups are preschool children, students, farmers, and the elderly. The exposures are mainly related to vegetable foods and mixed foods in households and catering service establishments. Efforts should be made to strengthen food safety awareness, health education, and supervision targeting residents and food operators in order to reduce the incidence of foodborne diseases in the Wenchang area.

Objective:To explore the teaching effect of magnetic on-demand teaching mode in nursing interns of neurology department.Methods:Forty-two nursing students who practiced in Neurology Department of Haikou People's Hospital from July 2019 to December 2019 were selected as the control group, and 44 nursing students who practiced from January 2020 to June 2020 were selected as the study group. The traditional teaching mode was adopted in the control group, while the magnetic on-demand teaching mode was adopted in the study group. The scores of theory and skill examination after teaching, nurses' core competence (evaluated by nurse core competence scale) before and after teaching, active learning rate and incidence of nursing errors during teaching and satisfaction with teaching were compared between the two groups. SPSS 25.0 was used for t test and chi-square test. Results:After teaching, the scores of theory and skills in the study group were significantly higher than those in the control group ( P<0.05). After teaching, the scores of core competence of nurses in the two groups were higher than before, and the scores of core competence of nurses in the study group were higher ( P<0.05). During the teaching period, the active learning rate of the study group was higher than that of the control group ( P<0.05), and the incidence rate of nursing errors was lower than that of the control group ( P<0.05). The satisfaction of all kinds of teaching in the study group was higher than that in the control group, with statistically significant differences. Conclusion:In the clinical teaching of nursing interns in neurology department, the magnetic on-demand teaching mode can significantly enhance the mastery of nursing theory and skills, improve the core competence of nurses, improve the active learning rate and teaching satisfaction, and reduce the occurrence of nursing errors.

HBeAg seroconversion refers to the disappearance of HBeAg and the appearance of anti-HBe in chronic hepatitis B (CHB) patients with positive HBeAg in the past. HBeAg seroconversion marks the reductions in viral replication, immune tolerance, and liver inflammation and is an important monitoring indicator for evaluating disease conditions and the effect of CHB antiviral therapy, and it also indicates the endpoint of satisfactory treatment. Exploring the influencing factors for HBeAg seroconversion is of great significance to the selection of treatment regimens and the prognostic evaluation of CHB patients. This article mainly elaborates on the association of HBV with HBeAg seroconversion in CHB patients from the aspects of virological factors, host genetic factors, drug factors, and immunological factors.
