Objective:To investigate the effect of a rapid rehabilitation nursing model under the theoretical framework of Rogers' Science of Unitary Human Beings in the postoperative care of children undergoing radical operation on Hirschsprung's disease.Methods:A total of 91 children with Hirschsprung's disease and their parents who underwent radical surgery at the Children's Hospital Affiliated to Zhengzhou University (Henan Children's Hospital, Zhengzhou Children's Hospital) between January 2022 and January 2024 were selected by convenience sampling. Using a computer-generated random number table, they were randomly divided into an intervention group ( n=46) and a control group ( n=45). The control group received routine surgical nursing, while the intervention group received a rapid rehabilitation nursing model based on Rogers' theoretical framework in addition to routine care. Postoperative pain stress, anorectal function, gastrointestinal functional recovery, and parental satisfaction were compared between the two groups. Results:On the third postoperative day, the intervention group had lower scores on the FLACC scale, better anorectal function, and shorter times to first bowel sound, first anal exhaust, and first defecation than the control group. The overall parental satisfaction rate in the intervention group was 86.96% (40/46), higher than 51.11% (23/45) in the control group, and the differences were statistically significant (all P<0.05) . Conclusions:The rapid rehabilitation nursing model under the theoretical framework of Rogers' Science of Unitary Human Beings showed significant effectiveness in children undergoing radical operation on Hirschsprung's disease. It reduced postoperative pain, promoted recovery of anorectal and gastrointestinal function, and improved parental satisfaction.

Mitochondrial diabetes mellitus(MDM)is a genetically heterogeneous disorder caused by mitochondrial DNA(mtDNA)or nuclear DNA mutations,characterized by multi-system involvement and diverse clinical phenotypes.We report a pediatric case presenting with growth retardation followed by subsequent development of diabetes mellitus.Systematic evaluation revealed concurrent bilateral sensorineural hearing loss,bilateral basal ganglia calcification,and electroencephalographic abnormalities.A post-exercise lactate test demonstrated significant elevation of serum lactate levels immediately after physical exertion.Genetic analysis identified a large-scale mitochondrial DNA deletion spanning from m.8649 to m.16084.This case re-port is complemented by a literature review focusing on the pathogenesis,genetic characteristics,and therapeu-tic approaches of mitochondrial diabetes,with particular emphasis on mitochondrial disorders exhibiting large-scale mtDNA deletions alongside diabetic manifestations.Our comprehensive analysis aims to enhance clinical understanding and inform diagnostic strategies for this complex disease entity.

Objective To analyze the differences in clinical indicators between malignant insulinoma and benign in-sulinoma,in order to provide diagnostic and therapeutic insights for the early detection and diagnosis of malignant insulinoma.Methods A retrospective analysis was conducted in patients diagnosed and treated for insulinoma at Peking Union Medical College Hospital from January 2018 to June 2022.Among them,10 cases were diagnosed as malignant insulinoma.Twenty cases of benign insulinoma patients matched for age,sex,and body mass index(BMI),were randomly selected.Statistical analysis was performed to compare the differences between malignant and benign insulinomas.Results 1)Compared to benign insulinoma,malignant insulinoma showed significantly ele-vated C-peptide(CP)and C-peptide to glucose ratio(CPGlu)during hypoglycemia(blood glucose＜3.0 mmol/L)[6.04(3.40,6.76)vs 1.68(1.39,2.47)ng/mL,P＜0.05),2.25(1.12,3.58)vs 0.74(0.54,1.54),P＜0.05].The tumor diameter(DIA)was larger(1.9±0.6 vs 1.4±0.3 cm,P＜0.05),and the insulin level at 300 minutes(INS300)during the 5-hour oral glucose tolerance test(5 h OGTT)was significantly elevated(30.47±5.67 vs 9.67±3.32)μIU/mL,P＜0.01).Levels of blood tumor markers AFP,CEA,and CA724 were also increased(P＜0.05).2)Correlation analysis indicated that CP,CPGlu,DIA,INS300,AFP,CEA,and CA724 were positively correlated with malignant insulinoma during hypoglycemia.3)The ROC curve analysis suggested that the optimal cut-off points for distinguishing malignant from benign insulinomas were CP 2.49 ng/mL,CPGlu 1.31,DIA 1.85 cm,and INS300 20.22 μIU/mL,respectively.Conclusions In clinical practice,if an insulinoma patient has a CP level higher than 2.49 ng/mL and a tumor diameter larger than 1.9 cm during hypoglycemia,the possibility of malignant insulinoma should be considered,warranting further examinations and enhanced follow-up.Persistent elevation of AFP,CEA,and CA724 may indicate malignant insulinoma.

Objective:To construct and evaluate a training program for cardiovascular nurse specialists based on a core competency framework.Methods:Among 61 trainees participating in the first training class for cardiovascular nurse specialists organized by a provincial nursing society, a training program focusing on the nine core competencies for cardiovascular nurse specialists was implemented, which consisted of 4-week theoretical and 4-week practical training. The effectiveness of the training program was evaluated using the Kirkpatrick model. Data analyses were performed by using SPSS 26.0. Categorical data were presented as the number of cases; continuous variables in normal distribution were expressed as mean±standard deviation; and continuous variables in non-normal distribution were presented as median (interquartile range) and compared using non-parametric tests.Results:At the reaction level, the satisfaction rates of trainees with the theoretical and practical sections of the training program were 98.36% (60/61) and 95.08% (58/61), respectively. At the learning level, the comprehensive assessment score of the trainees was (83.01±3.39) points, and all of them successfully obtained their completion certificates, with a pass rate of 100.00% (61/61). At the behavior level, the core competencies for cardiovascular nurse specialists were significantly improved after training [the total score increased from 291.00 (254.00, 334.25) to 410.50 (354.50, 433.00), P<0.001]. At the results level, at six months after training, there were significant increases in the number of participants engaging in cardiovascular care practices, clinical nursing education and guidance, leadership roles, and research projects within their units as well as the number of individuals achieving career advancement (all P<0.05). Conclusions:The trainees are highly satisfied with the core competency-focused cardiovascular nurse training program, which can improve core competencies and cardiovascular nursing capabilities, expand the scope of cardiovascular nursing services, and foster the sustained advancement of the participants.

Objective To identify the relationship between physical activity,insulin resistance and cardiovascular risk in individuals with different glucose tolerance status and to provide evidence for exercise intervention in people with different glucose tolerance status.Methods A total of 691 patients with different glucose metabolism status were recruited as subjects of the research.Spearman correlation analysis was used to study the relationship between exercise frequency and insulin resistance,insulin sensitivity,neck circumference(NC)and neck circumference height ratio(NHtR)in the subjects with different glucose metabolism status,the relationship between NC and insu-lin resistance and insulin sensitivity in different glucose metabolism groups.Results 171(62.9%)Subjects with diabetes were intervened by exercised every day.Spearman correlation analysis showed the correlation between exer-cise frequency and tri-glyceride triglyceride-glucose index(TyG index)(r=-0.120,P＜0.05)and NC(r=-0.168,P＜0.05)were negatively correlated.In subjects with diabetes,NC was positively correlated with triglyc-erides(TG)(r=-0.100,P＜0.05),homeostasis model assessment of insulin resistance(HOMA-R)(r=-0.163,P＜0.05),total cholesterol/high-density lipoprotein(TC/HDL-C)(r=-0.214,P＜0.05)and TyG index(r=-0.156,P＜0.05).Conclusions Increased frequency of exercise is associated with reduced NC,improved insulin resistance,and cardiovascular risk factors in subjects of our team with newly diagnosed diabetes.Exercise has no significant effect on insulin resistance of subjects with normal glucose tolerance and pre-diabetes.

Objective To investigate the effects of metformin(Met)on the proliferation of pancreatic cancer cells under different glucose concentration culture conditions,and to find the potential role of miR-139-5p in the process.Methods PANC-1 cells were treated with different concentrations of metformin(0/5/10/20 mmol/L)in 25 mmol/L(high-glucose group,HG)or 5 mmol/L(normal-glucose group,NG)glucose culture,cell proliferation,apoptosis,migration and cell cycle were detected after 48 h.The expression of miR-139-5p was quantitatively detected by RT-qPCR,and the miR-139-5p mimics were transfected into PANC-1 cells to clarify the role of miR-139-5p.Results Metformin inhibited the proliferation,promoted apoptosis,and induced S phase and G2/M phase arrest of PANC-1 cells under in high glucose and normal glucose culture conditions,and its anti-proliferation and pro-apoptosis effects were more significant in the normal glucose groups.The expression of miR-139-5p was up-regu-lated by metformin treatment in normal but not in high glucose culture.Further studies showed that miR-139-5p mimics inhibited of PANC-1 cells proliferation without metformin pre-incubation and enhanced the anti-prolifera-tion effect of 5 mmol/L metformin.The pro-apoptotic effect of 10 mmol/L metformin in normal glucose culture conditions.Conclusions In normal-glucose culture conditions,metformin can inhibit proliferation,induce apop-tosis and cell cycle arrest of PANC-1 cells more significantly than in higher-glucose culture,which may be partly related to the up-regulation of miR-139-5p.

Objective　To study the relationship between the balance of helper T cell 17 (Th17)/regulatory T cell (Treg) and the expression levels of related cytokines such as interleukin 17 (IL-17), in key endemic areas of Hubei Province for previous schistosomiasis patients, to provide new targets for effective clinical assessment of the state of schistosomiasis. Methods A simple random sampling method was used to select previous schistosomiasis patients from Jiangling County, Jingzhou City, Hubei Province in 2023. And 15 cases were identified as the patient group (P group). Fifteen matched healthy individuals undergoing physical examination at the Hubei Provincial Center for Disease Control and Prevention in 2023 were selected as the control group (C group). The general and clinical data of the two groups were compared, along with the content of peripheral blood Th17, Treg, Th17/Treg ratio, and expression levels of related cytokines such as IL-17, IL-22, tumor necrosis factorα (TNF-α), interleukin 10 (IL-10), and transforming growth factor β1 (TGF-β1). The t-test was used to analyze the levels of Th17/Treg cell balance and related cytokines (e.g., IL-17) between the patient and control groups. Pearson correlation analysis was used for correlation analysis. Results There were no statistically significant differences between the two groups in terms of gender, age, height, and body mass (P>0.05). The serum biochemical indicators alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the patient group [(75.24±12.73) U/L, (61.96±11.82) U/L] were elevated compared to the control group [(18.42±1.21) U/L, (16.35±0.92) U/L], with statistically significant differences (P<0.05). The percentage of Th17 cells in the patient group was higher than that in the control group, and the Th17/Treg cell ratio was increased, with statistically significant differences (P<0.05). There was no statistically significant difference in the percentage of Treg cells between the two groups (P>0.05). The expression levels of IL-17 in peripheral blood were higher in the patient group compared to the control group, with a statistically significant difference (P<0.05), while the expression levels of IL-22, TNF-α, IL-10, TGF-β1 showed no statistically significant differences (P>0.05). The levels of Th17 (%) and cytokine IL-17 in the peripheral blood of the patient group were significantly positively correlated with ALT and AST (P<0.05). Conclusions Influenced by factors such as inflammatory reactions and immune dysfunction, the subjects of this study showed an increase in the Th17/Treg ratio of previous schistosomiasis patients, resulting in an imbalance of Th17/Treg cells and abnormal expression of cytokine IL-17. Therefore, detecting the expression of Th17/Treg cells and their related cytokines may provide a reference for the clinical assessment and symptomatic treatment of schistosomiasis.
