Objective To investigate the correlation between insulin resistance and interleukin-6 (IL-6), chemerin, total cholesterol (TC)/high density lipoprotein cholesterol (HDL-C) ratio, triglyceride (TG)/HDL-C ratio, low density lipoprotein cholesterol (LDL-C)/HDL-C ratio and insulin resistance in obese patients with type 2 diabetes mellitus (T2DM), and to provide scientific basis for T2DM prevention and control. Methods A total of 355 obese T2DM patients in Songjiang Hospital Affiliated to Shanghai Jiaotong University School of Medicine were selected from January 2021 to December 2023. IL-6, chemerin and lipids were detected, and the assessment of insulin resistance was conducted through the homeostasis model assessment of insulin resistance (HOMA-IR). Results Among the 355 obese T2DM patients, there were 280 cases of insulin resistance, with the incidence rate of 78.87%. The BMI, IL-6, chemerin, TC/HDL-C, LDL-C/HDL-C, and TG/HDL-C in the insulin resistance group were higher than those in the non-insulin resistance group (P<0.05). The above insulin resistant patients were divided into 4 subgroups by means of insulin resistance, and there were significant differences in BMI, IL-6, chemerin, and TG/HDL-C among the subgroups (P<0.05). IL-6, chemerin, and TG/HDL-C were positively correlated with HOMA-IR in obese T2DM patients (P<0.05), while TC/HDL-C and LDL-C/HDL-C had no significant correlation with HOMA-IR (P>0.05). BMI, IL-6, chemerin, and TG/HDL-C were all influencing factors of insulin resistance in obese T2DM patients (P<0.05). Conclusion IL-6, chemerin and TG/HDL-C are correlated with insulin resistance in obese patients with T2DM and are influencing factors for the occurrence of insulin resistance.

OBJECTIVES: To explore the mechanism through which moxibustion promotes endometrial repair in rats with in thin endometrium (TE). METHODS: Female SD rats were randomized into control group, 95% anhydrous ethanol-induced TE model group and moxibustion (at "Guan Yuan") group. High-throughput sequencing was used to identify the target genes of TE, and the targeting relationship between miR-223-3p and NLRP3 was verified using a dual luciferase assay. Histopathological of rat uterus was observed with HE staining, and expressions of miR-223-3p and NLRP3 were detected using RT-qPCR; serum levels of IL-1β and IL-18 of the rats were detected using ELISA, and protein expressions of NLRP3, ASC, caspase-1 and GSDMD in the uterus were detected with Western blotting. The pregnancies of the rats after treatment were counted. RESULTS: Enrichment analysis of the differential genes suggested up-regulated inflammatory response in TE, and dual luciferase assay verified targeted inhibition of NLRP3 expression by miR-223-3p. The rat models of TE had significantly decreased endometrial thickness and reduced endometrial glands and blood vessels with enhanced mRNA expression of NLRP3, increased serum levels of IL-1β and IL-18, up-regulated protein expressions of NLRP3, ASC, caspase-1 and GSDMD, lowered pregnancy rates on both the affected and unaffected sides and the overall number of pregnancies. Treatment of the rat models with mo-xibustion obviously increased the endometrial thickness and the density of glands and blood vessels, up-regulated miR-223-3p expression, lowered serum IL-1β and IL-18 levels and the protein expressions of NLRP3, ASC, caspase-1 and GSDMD, and significantly increased the number of pregnancies. CONCLUSIONS Moxibustion at "Guan Yuan" acupoint up-regulates the expression of miR-223-3p, which results in targeted inhibition of NLRP3 to suppress pyroptosis and promote endometrial repair in rat models of TE.

Objective:To explore the chain mediation effects of psychological resilience and fear of falling on family function and rehabilitation exercise adherence among stroke patients of different genders.Methods:Totally 298 stroke patients from Xinxiang Central Hospital between January and December 2023 were selected by convenience sampling. Participants were assessed using the Family Assessment Device (FAD), Connor-Davidson Resilience Scale (CD-RISC), Fear of Falling Questionnaire-Reversed (FFQ-R), and Exercise Adherence Questionnaire (EAQ). The SPSS PROCESS macro was utilized to test the chain mediation effects.Results:Male stroke patients had higher total FAD scores, communication, and family role dimension scores, total CD-RISC scores, resilience and self-reliance dimension scores, and EAQ scores, including adherence to physical exercise and exercise supervision, compared to female patients ( P<0.05). However, female patients scored higher in emotional response and emotional involvement dimensions of FAD, total FFQ-R, and all dimensions of FFQ-R, as well as adherence to seeking timely advice of EAQ ( P<0.05). Mediation analysis showed that in male stroke patients, family function had no significant direct effect on rehabilitation exercise adherence (95% CI: -0.055 - 0.096), with psychological resilience and fear of falling playing a fully mediating role; the total mediation effect was 0.113, accounting for 84.96% of the total effect. In female stroke patients, family function had a significant direct effect on rehabilitation exercise adherence, with an effect of 0.110, accounting for 42.80% of the total effect. In addition, psychological resilience and fear of falling partially mediated the relationship between family function and rehabilitation exercise adherence, with a total mediation effect of 0.147, accounting for 57.20% of the total effect. Conclusions:The levels of family function, psychological resilience, fear of falling, and rehabilitation exercise adherence, as well as the mechanisms linking these factors, differ by gender in stroke patients. In male stroke patients, psychological resilience and fear of falling fully mediate the relationship between family function and rehabilitation exercise adherence. In female stroke patients, family function influences rehabilitation exercise adherence through both direct effects and the partial mediating effects of psychological resilience and fear of falling.

Objective To develop a risk prediction model for postoperative malnutrition in children with congenital heart disease(CHD)and to verify it both internally and externally.Methods By a convenience sampling method,300 CHD children treated at a tertiary hospital in Shandong Province from January 2018 to December 2021 were selected as a modeling group,and 129 children from January 2022 to June 2023 were selected as a validation group.Data on patient demographics,disease-specific variables,therapeutic interventions,and nursing care parameters were collected.Single factor and logistic regression were employed to construct a risk prediction model for postoperative malnutrition in CHD children,and the nomogram was drawn and its prediction effect was evaluated.Results The incidence of postoperative malnutrition among CHD children was 33.10％.Logistic regression analysis revealed that risk factors for malnutrition in children included birth weight＜2.5 kg,preoperative malnutrition,negative fluid balance 1 week after surgery,and long duration of cardiopulmonary bypass(P＜0.05).The area under the receiver operating characteristic curve of the modeling group was 0.933;the sensitivity was 83.30％;the specificity was 90.90％.The Hosmer-Lemeshow test showed that x2=7.765(P=0.457).The AUC of the validation group was 0.918;the sensitivity was 87.20％;the specificity was 90.00％.The Hosmer-Lemeshow test showed that x2=4.947(P=0.763).Calibration curves for both groups indicated good calibration of the model,and the clinical decision curves demonstrated its practical clinical utility.Conclusion The risk prediction model developed in this study exhibits good predictive ability,which can provide a reference for medical staff to early identify high-risk infants for postoperative malnutrition following CHD surgery and to formulate targeted intervention measures.

Patients with skeletal ClassⅡ often show symptoms such as protrusion of maxillary anterior teeth,mandibular retraction,open lips and teeth,deep overbite,and deep overjet,which seriously affect the facial appearance.This article reports a case of an ado-lescent male patient with skeletal Class Ⅱ combined with impacted teeth treated by one-stage early correction and two-stage fixation.After treatment,the patient's skeletal Class Ⅱ symptoms improved significantly,including the improvement of mandibular retraction.The problem of open lips and teeth was solved;the facial appearance tended to be straight,and there was no obvious abnormality of the temporomandibular joint.This case shows that early correction can achieve good therapeutic effects on this kind of patients and can avoid or reduce the possibility of orthognathic surgery for these patients in adulthood.

Objective:To discuss the differences in eosinophil(EOS)infiltration in cervical tissue and its relationship with cervical-related diseases,and to clarify the effect of EOS on the occurrence and development of cervical intraepithelial neoplasia(CIN)and cervical cancer.Methods:The clinical data of 256 patients with cervical diseases were collected and divided into cervical cancer group(n=46,including 26 cases of squamous cell carcinoma,15 cases of adenocarcinoma,and 5 cases of adenosquamous carcinoma),chronic cervicitis group(n=50),CIN stage Ⅰ group(n=50),CIN stage Ⅱ group(n=50),CIN stage Ⅲ group(n=30),and normal group(adjacent normal cervical tissue,n=30)based on their conditions.Colposcopy was used to observe the morphology of cervical tissue of the patients in various groups;thin-layer liquid-based cytology test(TCT)was used to observe the morphology of the cervical exfoliated cells in various groups;hybrid capture-chemiluminescence method was used to detect the human papillomavirus(HPV)infection in cervical tissue of the patients in various groups;HE staining was used to observe the pathomorphology of cervical tissue of the patients in various groups;Congo red staining was used to detect the numbers of EOS infiltration in cervical tissue of the patients in various groups;Pearson correlation analysis was used to analyze the correlation between the number of EOS infiltration and the malignancy degree of cervical cancer.Results:The cervical surface of the patients in normal group was smooth and pink,with uniformly distributed capillaries;the cervical surface of the patients in chronic cervicitis group showed red inflammatory changes,with some accompanied by Nabothian cysts and varying degrees of erosion and ulcers;the patients in CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups showed epithelial ulcers,thickening,and irregular morphology,with mosaic and punctate vessels;the cervical surface of the patients in cervical cancer group showed raised areas with neoplasms and necrotic ulcers,and they were fragile and prone to bleeding.After acetic acid staining,no obvious changes of the patients in normal group were observed.The cervix of the patients in chronic cervicitis group showed slight white changes that lasted for a short time;in CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups,irregular thin acetowhite epithelium with map-like borders was observed,with increasingly acetowhite reactions and larger areas as the stages advanced.The cervix of the patients in cervical cancer group showed thick acetowhite epithelium that lasted longer,with rigid and clear contours.After iodine staining,the cervix of the patients in normal group was brown,with uniform coloration;the cervix of the patients in chronic cervicitis group showed poor coloration in inflammatory lesion areas;the cervix of the patients in CIN stage Ⅰ group showed iodine coloration in metaplastic areas,while the cervix of the patients in CIN stage Ⅲ group showed poor coloration in larger lesion areas;the cervix of the patients in cervical cancer group showed irregular surfaces with cauliflower-like growth and no coloration after iodine staining,appearing orange-yellow or mustard yellow.The TCT observation results showed there were no heteromorphic cells and few inflammatory cells in cervical exfoliated cells of the patients in infiltration in normal group;there were numerous neutrophils and EOS in exfoliated cervical cells without heteromorphic cells in chronic cervicitis group.The heteromorphic binucleated cells with high nuclear-cytoplasmic ratios and deeply stained nuclei were observed in cervical exfoliated cells of the patients in CIN stage Ⅰ and CIN stage Ⅱ groups.More heteromorphic cells with high nuclear-cytoplasmic ratios and irregular nuclear membranes were showed in cervical exfoliated cells of the patients in CIN stage Ⅲ group.The cervical exfoliated cells of the patients in cervical cancer group showed large and prominent nucleoli,clustering into syncytial changes.Compared with normal group,the atypial of cervical exfoliated cells in CIN stage Ⅰ,CIN stage Ⅱ,CIN stage Ⅲ,and cervical cancer groups was increased.The hybrid capture-chemiluminescence results showed that compared with normal and chronic cervicitis groups,the numbers of HPV infection and TCT heteromorphic cells of the patients in CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups were increased(P<0.05);compared with CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups,the numbers of HPV infection and TCT heteromorphic cells of the patients in cervical cancer group were increased(P<0.05).The HE staining results showed normal cell morphology and structure in normal group,with infiltration of inflammation cells such as neutrophils,monocytes,macrophages,EOS,and lymphocytes;in chronic cervicitis group,the infiltration of inflammatory cells was increased;in CIN group,the cervical cells showed slightly larger nucleoli and heteromorphic cells,with inflammatory cells mainly distributing around the hetermomorphic cells;in cervical cancer group,the cervical cells showed large and deeply stained nucleoli with significant atypia,and the infiltration of inflammatory cells around the cancer cells was increased.Compared with normal group,the numbers of inflammatory cells and EOS infiltration in cervical tissue of the patients in chronic cervicitis group were increased(P<0.05),and the numbers of inflammatory cells and EOS infiltration of the patients in CIN group were increased(P<0.05);compared with chronic cervicitis group,the number of inflammatory cells and EOS infiltration of the patients in CIN group were decreased(P<0.05);compared with chronic cervicitis group and CIN group,the numbers of inflammatory cells and EOS infiltration of the patients in cervical cancer group were increased(P<0.05).The EOS in cervical cancer tissue was mainly distributed around the cancer nests;compared with CIN stage Ⅰ group,the numbers of EOS infiltration in CIN stage Ⅱ and CIN stage Ⅲ groups were increased(P<0.05);compared with CIN stage Ⅱ group,the number of EOS infiltration in CIN stage Ⅲ group was increased(P<0.05).The higher the malignancy degree of the tumor,the more EOS infiltration was observed,and the number of EOS infiltration was positively correlated with the invasion depth of cervical cancer(r=0.533 0,P<0.01).Conclusion:HPV infection and EOS infiltration play a role in promoting the and occurrence development of cervical precancerous lesions and cervical cancer.

Ischemic stroke,with a high disability and mortality rate,seriously endangers human health.Pathological process of ischemic stoke involves participations of various cells such as microglia and astrocytes.Among them,microglia,as innate immune cells in central nervous system(CNS),play an important role whether in physiological or pathological states.Triggering receptor expressed on myeloid cells 2(TREM2)is an immunoglobulin like receptor mainly existing on microglia in CNS,and can bind to a variety of ligands,which can negatively regulate autoimmunity and inflammation.In addition,TREM2 can mainly play an important role in process of proliferation,phagocytosis,survival and expressions of inflammatory factors.This article focused on biological characteristics of TREM2 on microglia,corresponding ligands and its signaling pathways,discussing regulation of TREM2 in ischemic stroke and its potential therapeutic effects,in order to provide an new target for prevention and treatment of ischemic stroke.
