Objective To explore the changes in neural activity in patients with type 2 diabetes mellitus(T2DM)and their corre-lation with executive function,and to analyze the neural mechanisms underlying the decline in executive function in T2DM patients.Methods Thirty-one T2DM patients(T2DM group)and thirty-two healthy controls(HC)(HC group)matched for body mass index(BMI)underwent resting-state functional magnetic resonance imaging(rs-fMRI)scans and N-back task tests were included.Differ-ences in the amplitude of low-frequency fluctuation(ALFF),regional homogeneity(ReHo),and seed-based functional connectivity(FC)between the two groups were compared,and partial correlation analyses were performed between the difference results and N-back task performance.Results The T2DM group showed prolonged reaction time(RT)in the 1-back and 2-back tasks.T2DM patients exhibited increased ALFF in the bilateral caudate nucleus,left medial superior frontal gyrus,and right postcentral gyrus,as well as elevated ReHo in the right putamen.FC analysis revealed significant alterations in FC between the caudate nucleus,putamen,and multiple brain regions in T2DM patients,with some of these FC changes significantly correlated with RT and accuracy(ACC)in the N-back task.Conclusion The decline in executive function in T2DM patients may be associated with abnormal neural activity in brain regions such as the striatum,salience network,and frontoparietal control network.FC further decreases under increased cognitive load.These findings provide evidence for the study of the neural mechanisms of executive function impairment in T2DM patients.

This article summarizes the experience of providing remote nursing care for a pediatric patient with severe burns using augmented reality(AR)technology.Key nursing points include:to establish a remote management team to enhance multidisciplinary collaboration;to conduct remote nursing ward rounds to provide real-time guidance for clinical nursing practice;to remotely guide PICC(Peripherally Inserted Central Catheter)insertions and conduct precise fluid management;to remotely assess ward environments and provide guidance on disinfection and isolation measures;to alleviate pediatric pain through comprehensive management measures.After meticulous care and treatment,the patient's condition stabilized after 23 days,and the patient was transferred to a specialized hospital for continued treatment requiring skin grafting.

For TCM to go global,while carrying forward its own characteristics,it should also build a set of measurement methods recognized by the international medical field.PRO scale is more and more widely used in the field of traditional Chinese medicine because there are many confluence points between PRO scale and TCM connotation.The patient-reported outcomes measurement information system(PROMIS)provides a reference for the development of PRO scales in the field of TCM.We can learn from the methods and models relied on by PROMIS and build a PRO evaluation system for TCM diseases based on TCM culture,so as to promote the standardization,standardization and modernization of TCM.

Starting from the connotation of "New Medicine" in the context of Healthy China, Guangxi Medical University has launched a reform of medical humanities education based on the concept of holistic medicine and the competency-based approach. With the construction of first-class courses and majors as the starting point, the university aims to position itself, clarify goals, and innovate concepts based on "value orientation", and it reconstructs the education system and reshapes the education model with the integration of medical humanities and the combination of learning and practice, thereby establishing a holistic education system with the integration of medical humanities centered on longitudinally sequenced medical humanities curricula. The university also constructs a participatory teaching method based on online-offline platforms, pre-class/post-class engagement, and on-campus/off-campus collaboration, as well as a teaching assessment system with multiple subjects, multiple dimensions, dynamic evolution, and virtue orientation. The university has also built a diversified collaborative educational practice platform among universities, hospitals, and communities, thereby forming a comprehensive medical humanities teaching model with the teaching of humanistic knowledge, the cultivation of humanistic spirit, and the training of good behaviors.

Objective:To investigate the possible mechanism of Zaogong Erteng decoction (ZGETD) in the treatment of endometritis.Methods:Femal mice were injected 2.5 mg/mL lipopolysaccharide into uterine horn to induce endometritis model. After modelling, low-dose ZGETD, high-dose ZGETD or amoxicillin was given once a day for 7 d. The appearance of the uterus and pathological changes of uterine tissue were observed 7 d later, and the uterine index was calculated. The expression of tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6 in mouse uterine tissue was detected by enzyme-linked immunosorbent assay. The activity of myeloperoxidase (MPO) in mouse uterine tissue was measured by redox reaction. The active ingredients of ZGETD and the target and signal pathway of treatment of endometritis were analyzed by network pharmacology. Western blotting and qRT-PCR were used to detect the expressions of Toll-like receptor 4 (TLR4), P65, p-P65, interferon regulatory factor 3 (IRF3) and p-IRF3 proteins and chemokines CXCL5 and CXCL8 in the mouse uterus, respectively. Terminal dUTP nick end labeling detected endometrial cell apoptosis and endometrial thickness was measured. After treatment, the female rats were mated with the male rats, and the mating rate, the pregnancy rate and the number of implantation sits in the injected uterine horn on day 8 of gestation were counted. Results:Both ZGETD and amoxicillin have atherapeutic effect on endometritis, but compared with low-dose ZGETD and amoxicillin, high-dose ZGETD can significantly alleviate the edema and congestion of uterine tissue and reduce the uterine index (all P=0.001). After treatment, the uterine cavity epithelium of mice was smooth and complete, the uterine gland structure was normal, and no bleeding area and inflammatory cell aggregation were observed. Compared with amoxicillin, high-dose ZGETD significantly decreased the expression of inflammatory factors (TNF-α, IL-1β and IL-6) and MPO activity (all P<0.001). The expression of chemokines ( CXCL5 and CXCL8) was significantly reduced (all P<0.05). The signaling pathways TLR4, nuclear factor kappa-B (NF-κB) and TNF related to the treatment of endometritis by ZGETD were screened by network pharmacology, and their action targets (TLR4, NF-κB and IRF3) were verified. Quercetin, fisetin and luteolin were found to be the most active ingredients acting on these targets. High-dose ZGETD significantly inhibited the activation of TLR4/NF-κB and TLR4/IRF3 pathways ( P<0.05), decreased endometrial cell apoptosis ( P<0.05), and increased endometrial thickness ( P<0.001), mating rate ( P<0.001), pregnancy rate ( P<0.001) and implantation site number of uterine horn on the injection side of LPS after treatment ( P=0.001). Conclusion:High-dose ZGETD has a significant therapeutic effect on endometritis, which may be closely related to the down-regulation of TLR4 signaling pathway.

Intrauterine adhesions are adhesions of the uterine wall caused by damage to the basal layer of the endometrium, which will affect women's menstruation and fertility. At present, the effect of surgery and drug treatment is not ideal, and it is easy to relapse. Platelet-rich plasma (PRP) is a kind of plasma with high concentration of platelets obtained by centrifuging autologous blood, containing a variety of bioactive factors (platelet-derived growth factor, transforming growth factor-β, vascular endothelial growth factor, insulin-like growth factor 1, etc.), which can significantly promote cell proliferation and differentiation, angiogenesis, relieve inflammation and prevent infection, reduce fibrosis and be used as biological scaffold in the treatment of uterine adhesion. It can significantly improve endometrial morphology, reduce fibrosis and improve fertility. In view of the advantages of PRP in the treatment of intrauterine adhesions, this paper will discuss the characteristics, mechanism and application of PRP in the treatment of intrauterine adhesions, so as to further understand the important role of PRP in the treatment of intrauterine adhesions and lay a foundation for its clinical application.

his cross-sectional study employed convenience sampling to enroll 1 994 community-dwelling older adults (aged ≥65 years) undergoing health examinations at a Guangzhou community hospital between January and December 2024, aiming to investigate associations between blood lipid profiles and cognitive impairment. Cognitive function was assessed using the AD8 scale, with demographic characteristics (age, sex, education, occupation), health status (hypertension, diabetes mellitus), and lifestyle factors (smoking/alcohol use) collected via questionnaires. Fasting blood samples quantified triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). Propensity score matching (PSM) balanced baseline characteristics between lipid-level groups. Pre-PSM analyses revealed significant intergroup differences: TG groups differed in sex, BMI, alcohol use, hypertension, and self-rated health ( P<0.05); TC groups in sex, age, occupation, diabetes, and hypertension; LDL-C groups in sex, age, occupation, diabetes, hypertension, and daily living ability; HDL-C groups in sex, age, education, occupation, BMI, smoking, diabetes, and hypertension. Post-PSM adjustment eliminated baseline differences ( P>0.05). Multivariable logistic regression adjusted for demographic, clinical, and lifestyle factors demonstrated that elevated TG levels conferred a 48% reduced risk of cognitive dysfunction [ OR (95% CI): 0.52 (0.29-0.94)], whereas TC, LDL-C, and HDL-C showed no significant associations (all P>0.05). These findings suggest an inverse association between higher triglyceride levels and cognitive dysfunction risk in older adults, highlighting TG′s potential protective role in cognitive health.

The menopausal age is one of the important menopausal factors, and women of different menopausal ages have different risks of diabetes. This study reviewed the evidence from prospective studies on the association between the age at natural menopause and diabetes risk, both domestically and internationally, and presented its research design and main findings. Advanced menopause, especially premature and early menopause, will increase the risk of diabetes in postmenopausal women. The research on the influence of delayed menopause on the incidence of diabetes is still insufficient. Many factors may modify the association between menopausal age and the risk of diabetes.
