Objective To explore the correlation between serum macrophage migration inhibitory factor(MIF),25-hydroxyvitamin D[25(OH)D]and cognitive function in patients with vestibular migraine(VM).Methods A total of 200 patients with VM were selected and used as the VM group.Based on the Montreal Cognitive Assessment(MoCA)criteria,patients were divided into the cognitively normal group(128 cases)and the cognitively impaired group(72 cases).Additionally,200 healthy individuals undergoing routine health examination were selected as the control group.Serum MIF and 25(OH)D levels were measured using enzyme-linked immunosorbent assay.Multivariate Logistic regression was used to analyze influencing factors of cognitive impairment in VM patients.The value of serum MIF and 25(OH)D levels in diagnosing cognitive impairment in patients with VM was analyzed by using the receiver operating characteristic(ROC)curve.Results The serum MIF was higher in the VM group than that of the control group,and serum 25(OH)D was lower in the VM group(P＜0.05).The serum MIF was higher in the cognitive impairment group than that of the cognitive normal group,while the serum 25(OH)D was lower in the cognitive impairment group than that of the cognitive normal group(P＜0.05).Multivariate Logistic regression found that increased serum MIF level and decreased 25(OH)D level were independent risk factors for cognitive impairment in VM patients(P＜0.05).ROC curve analysis showed that the AUC(95%CI)of the combined diagnosis of cognitive impairment in VM patients using serum MIF and 25(OH)D levels was 0.900(0.850-0.938),which was higher than that of MIF diagnosed alone[0.797(0.735-0.851)]and 25(OH)D alone[0.817(0.756-0.868),P＜0.05].Conclusion VM patients with cognitive impairment have elevated serum MIF levels and decreased 25(OH)D levels.The combined diagnostic value of the two markers has a relatively high value for VM patients with cognitive impairment.

Purpose To analyse the expression of aldo-keto reductase AKR1C3 in the tumour tissues of oral squa-mous carcinoma(OSCC)and the correlation of clinical prognosis of patients.Methods Immunohistochemical(IHC)staining was performed to analyze the expression characteristics of AKR1C3 in 86 cases of OSCC tumor tissues and paired paratumor normal tissue.The correlation between AKR1C3 expression and clinical prognosis was evaluated.Ka-plan-Meier survival analysis was conducted to assess the survival outcomes of OSCC patients.Univariate and multivari-ate Cox regression analyses were employed to identify prognostic factors.The findings were further validated by compar-ison with the Cancer Genome Atlas(TCGA)database.Results The expression of AKR1C3 was significantly higher in OSCC tumor tissues than in paratumor normal tissue,with higher expression observed at the invasive front relative to the tumor centers.Immunohistochemical analysis revealed high expression in both tumor cells and tumor-associated fibro-blasts,while no expression was detected in tumor-infiltrating immunocytes.The x2 test was used to compare the rela-tionship between different expression levels of AKR1C3 and clinicopathological features in OSCC,the results showed that high expression of AKR1C3 was strongly associated with higher tumour stage(P=0.001),lymph node metastasis(P=0.023),differentiation(P=0.018),worst pattern of invasion(P=0.024)and depth of invasion(P=0.012).Kaplan-Meier survival curve analysis showed high expression of AKR1C3 was associated with overall survival(P=0.004),disease-free survival(P=0.019),and metastasis-free survival(P=0.05)in OSCC patients.Cox re-gression model was performed for prognostic analysis.Univariate analysis showed that high expression of AKR1C3 in tumour cells was a high-risk factor for patients' tumour stage(P＜0.001),lymph node metastasis(P＜0.001),dif-ferentiation(P＜0.001),worst pattern of invasion(P＜0.001),depth of invasion(P＜0.001).Multivariate analy-sis further showed that high expression of AKR1C3 in tumour cells was an independent prognostic factor in OSCC pa-tients(P=0.025).Conclusion The AKR1C3 expression is closely related to the prognosis of OSCC patients,and patients with high AKR1C3 expression have a poor prognosis,suggesting that AKR1C3 plays an important role in the occurrence and development of OSCC.

Objective:To analyze the incidence of surgical site infection (SSI) in patients undergoing colorectal cancer (CRC) surgery and to identify risk factors associated with SSI in an attempt to provide a reference for clinical prevention strategies.Methods:A retrospective cohort study was conducted. Clinical data were retrospectively collected from a total of 2,248 patients who underwent surgery for pathologically confirmed CRC between 2017 and 2022 at two centers: Huangshan Shoukang Hospital ( n=649) and Northern Jiangsu People's Hospital ( n=1 599). Inclusion criteria consisted of the following: (1) age >18 years; (2) pathologically confirmed CRC treated with curative resection, including extended resections (e.g. pelvic exenteration); (3) no surgical incisions other than abdominal or perineal; and (4) no use of prosthetic implants. The incidence of SSI was analyzed, and multivariate logistic regression was used to identify independent its risk factors. Results:A total of 121 patients (5.4%) developed SSI. Among them, 68 cases (56.2%) were organ/space infections, 35 cases (28.9%) were deep incisional infections, and 18 cases (14.9%) were superficial incisional infections. The median postoperative hospital stay was significantly longer in patients with SSI compared to those without (21.0 days vs. 13.0 days, U=65,754, P<0.001). The median hospitalization cost was also significantly higher in the SSI group (56,550 yuan vs. 43,645 yuan, U=72,008, P<0.001). Multivariate logistic regression analysis identified body mass index (BMI) ≤ 20 kg/m 2 (OR=4.25, 95%CI: 3.38-5.34, P<0.001), diabetes mellitus (OR=3.44, 95%CI: 1.89-6.24, P<0.001), open surgery (OR=4.23, 95%CI: 2.37-7.56, P<0.001), and colostomy or ileostomy (OR=1.67, 95% CI: 1.04-2.69, P=0.034) as independent risk factors for SSI. Conclusion:To prevent SSI following CRC surgery, attention should be given to optimizing body weight and glycemic control, promoting minimally invasive surgical approaches when feasible, and cautiously considering the necessity of colostomy or ileostomy.

Objective:To identify different subtypes of patients with preeclampsia(PE)through clinical liver function index data-driven the cluster analysis,to explore the correlation between liver function of different sub-types and pregnancy complications.Methods:From January 2012 to December 2022,the general data of 2230 sin-gleton pregnant women with PE who underwent prenatal examination and delivered in Fujian Maternity and Child Health Hospital were collected.Using 13 liver function indexes before delivery as baseline variables,all included subjects were classified into subtypes by cluster method.The clinical characteristics of different subtypes of PE patients were compared.Single-factor Logistic regression was used to analyze the risk of pregnancy complications among subtypes.Results:PE patients were divided into 3 subgroups that represented different characteristics of patients' liver function.The first subtype(n=1065)exhibited abnormal liver enzymology index characterized by in-creased alkaline phosphatase(ALP)level.The second subtype(n=648)showed abnormal bilirubin metabolism index with the highest levels of total bilirubin(TBIL),direct(DBIL)and indirect bilirubin(IBIL).The third subtype(n=517)had abnormal liver enzymology indexes with elevated alanine aminotransferase(ALT)and aspartate aminotransferase(AST)levels,abnormal bile acid detection indexes with elevated total bile acid(TBA)levels,and abnormal liver synthesis function indexes with decreased total protein(TP),albumin(ALB),and globulin lev-els(GLB).Significant differences were observed among the three subtypes in age,severe PE,anemia,cardiac dysfunction,and renal dysfunction(P＜0.05).Single-factor Logistic regression demonstrated that the third sub-type had significantly higher risks of intrahepatic cholestasis of pregnancy,fetal growth restriction,premature rup-ture of membranes,and preterm birth compared to the first and second subtypes(P＜0.05),as well as a higher risk of placental abruption than the second subtype(P＜0.05).The first subtype had higher risks of placental ab-ruption and fetal growth restriction than the second subtype(P＜0.05).Conclusions:Cluster analysis could be used to subclassify PE patients by liver function characteristics,so as to identify the occurrence of pregnancy complications.The results had significance for understanding the heterogeneity of PE and promoting individualized management.
