Objective:To explore the relationship between general demographic characteristics,inflammatory indicators,nutritional indicators,pathological data and lymph node metastasis in endometrial cancer(EC)pa-tients,and to construct and validate a model for preoperative prediction of lymph node status in endometrial canc-er patients.Methods:The preoperative clinical data of 473 patients with EC who underwent surgical treatment in the Zhu Jiang Hospital of Southern Medical University from January 2010 to April 2024 were retrospectively ana-lyzed.The independent risk factors of lymph node metastasis of endometrial cancer were screened by univariate and multivariate Logistic regression analyses,and the nomogram prediction model was constructed by R soft-ware.The performance of the model was evaluated by the receiver operating characteristic(ROC)curve,calibra-tion curve and clinical decision curve.Results:Menopausal status,high grade biopsy pathology,CA125 ≥24.47U/ml,systemic immune inflammatory index(SII)≥710.91,and prognostic nutritional index(PNI)＜52.90 were in-dependent risk factors for lymph node metastasis in endometrial cancer(OR＞1,P＜0.05).The nomogram model constructed based on these five factors had an AUC of 0.853 in the training set and 0.871 in the test set.The cali-bration curve fitted well,and the clinical decision curve shows a positive benefit.Conclusions:The endometrial cancer lymph node metastasis prediction model constructed based on menopausal status,biopsy pathology,CA125,SII,and PNI has good accuracy and fit,with certain clinical application value.

Objective To investigate the effect and mechanism of miR-195-5p on myocardial fibro-sis in rats with atrial fibrillation(AF).Methods A total of 72 male SD rats were randomly divid-ed into control group,AF group,negative control group,miR-195-5p inhibitor group,recombinant adeno-associated virus serotype 9(rAAV9)group(miR-195-5p inhibitor+rAAV9-negative con-trol),and combination group[miR-195-5p inhibitor+rAAV9-siRNA-SMAD homolog 7(Smad)],with 12 rats in each group.Except for the control group,the rats in the other groups were inflicted to construct AF model.After receiving corresponding intervention measures,elec-trocardiography was conducted to record the incidence and the duration of AF.HE staining and Masson staining were used to observe the pathological changes and fibrosis in the myocardial tis-sues,respectively.qRT-PCR was applied to detect the mRNA levels of miR-195-5p and Smad7,and Western blotting was performed to detect the expression of TGF-β1,Smad2,p-Smad2,Smad3,p-Smad3,Smad7,Collagen-Ⅰ and Collagen-Ⅲ in the myocardial tissues.Dual luciferase assay was used to verify the regulatory effect of miR-195-5p on Smad7.Results Compared with the control group,the AF group had significantly higher AF incidence(75.0％vs 0)and longer duration(27.02±2.65 s vs 0 s),larger collagen volume fraction(CVF)[(14.47±0.89)％vs(2.12±0.35)％],and increased expression levels of miR-195-5p(3.27±0.21 vs 1.00±0.10),TGF-β1(0.76±0.08 vs 0.23±0.04),Collagen-Ⅰ(0.58±0.07 vs 0.20±0.04),Collagen-Ⅲ(0.46±0.05 vs 0.11±0.02),p-Smad2/Smad2(0.92±0.10 vs 0.37±0.05),and p-Smad3/Smad3(0.65±0.06 vs 0.14±0.03),but notably decreased expression of Smad7 at mRNA(0.32±0.06 vs 1.02±0.09)and protein(0.19±0.03 vs 0.58±0.07)levels in the myocardial tissues(P＜0.05).The AF incidence and duration,CVF,miR-195-5p level,and protein levels of TGF-β1,Collagen-Ⅰ,Colla-gen-Ⅲ,p-Smad2/Smad2,and p-Smad3/Smad3 were significantly decreased,and the mRNA and protein levels of Smad7 were significantly increased in the miR-195-5p inhibitor group than the AF group and the negative control group(P＜0.05).The combined treatment increased the inci-dence and duration of AF,CVF,myocardial TGF-β1,Collagen-Ⅰ,Collagen-Ⅲ,p-Smad2/Smad2 and p-Smad3/Smad3 expression levels,and decreased the mRNA and protein expressions of Smad7 when compared with the miR-195-5p inhibitor group and the rAAV9 group(P＜0.05).Conclusion Down-regulation of miR-195-5p alleviates myocardial fibrosis in AF rats probably by targeting Smad7 to inhibit TGF-β1 signaling.

A 36-year-old male developed unconsciousness and no response to voice stimuli after taking approximately 2 050 mg felodipine (the specific time was unknown). Two hours later, he was sent to the department of emergency by his family and admitted to the hospital. His vital signs showed body temperature 35.1 ℃, pulse 148 times/min, respiration 32 times/min, and blood pressure 65/34 mmHg. Acute drug poisoning, acute toxic cardiomyopathy, acute toxic shock, acute type Ⅱ respiratory failure, acute toxic encephalopathy, and acute renal failure were diagnosed based on the patient′s clinical manifestations combined with laboratory tests results, cardiac ultrasound, chest and abdominal CT scans. Endotracheal intubation connected to a ventilator for invasive assisted ventilation, pressure boosting, and fluid resuscitation were given. At the same time, repeated gastric lavage and enema were performed to remove toxins. Blood perfusion was intermittently and repeatedly administered, and continuous renal replacement therapy was used. The blood concentration of felodipine was 1 298 μg/L at 2 hours after admission, and cardiac arrest occurred at 4 hours. Venous-arterial extracorporeal membrane oxygenation (V-A ECMO) treatment was administered immediately. After 48 hours of ECMO operation, sedatives were discontinued and the patient′s consciousness was improved after 4 hours. On the 5th day of ECMO treatment, his heart rate was 72 beats per minute, and blood pressure was 127/65 mmHg. The blood concentration of felodipine decreased to 2 μg/L. The patient′s vital signs were significantly improved and ECMO supportive treatment was withdrawn. After 26 days of hospitalization, the patient recovered and was discharged.

Objective:To investigate the association between metabolic dysfunction-associated steatotic liver disease(MASLD)and the risk of adverse pregnancy outcomes,and to analyze the impact of the type and severity of cardiometabolic risk factor(CMRF)abnormalities on this association.Methods:A retrospective cohort study was conducted among primiparous women with singleton pregnancies who had registered at Beijing Friendship Hospital from March 10,2020,to December 31,2022.A total of 2 623 women were included.Basic characteristics and delivery outcomes were documented,liver ultrasound and relevant prenatal examinations were performed,and adverse pregnancy outcomes were diagnosed.Modi-fied Poisson regression models were used to analyze the association between MASLD and adverse pregnan-cy outcomes.The relationship between the type or severity of CMRF abnormalities in MASLD and the risk of adverse pregnancy outcomes was also explored.Results:After adjusting for confounding factors including age,gestational weight gain,and education level,MASLD was associated with an increased risk of cesarean section(RR=1.531,95％CI:1.304-1.799,P＜0.001),gestational diabetes melli-tus(GDM;RR=2.409,95％CI:1.948-2.979,P＜0.001),pregnancy-associated hypertension(PAH;RR=3.062,95％CI:2.069-4.533,P＜0.001),preterm birth(RR=2.145,95％CI:1.342-3.429,P=0.001),and large for gestational age(LGA;2.224,95％CI:1.599-3.095,P＜0.001).However,no significant associations were found for small for gestational age or postpartum hemorrhage.After adjusting for other CMRF abnormalities,the risk of adverse pregnancy outcomes varied among MASLD pregnant women with different CMRF abnormalities:the body mass index abnormal group had higher risks of cesarean section,GDM,PAH,preterm birth,and LGA;the glucose abnormal group had an increased risk of GDM;the blood pressure abnormal group had a higher risk of PAH;the high density lipoprotein cholesterol abnormal group had higher risks of cesarean section,GDM,and PAH;and the tri-glyceride abnormal group was associated with higher risks of GDM and preterm birth.Additional,as the severity of CMRF abnormalities increased,the risks of cesarean section(RR=1.199,95％CI:1.112-1.292,P＜0.001),GDM(RR=1.478,95％CI:1.345-1.624,P＜0.001),PAH(RR=1.626,95％CI:1.367-1.934,P＜0.001),preterm birth(RR=1.384,95％CI:1.120-1.710,P=0.003),and LGA(RR=1.422,95％CI:1.224-1.650,P＜0.001)continued to rise.Conclusion:MASLD during pregnancy is associated with an increased risk of multiple adverse pregnancy outcomes,and the type and severity of CMRF abnormalities significantly influence this association.These results suggest that attention should be paid to the specific CMRF abnormalities when diagnosed MASLD,as this may help to facilitate targeted interventions and reduce the risk of adverse pregnancy outcomes.

Autoimmune enteropathy (AIE) is an autoimmune disease with unclear pathophysiological mechanisms. It was more commonly observed in children but is increasingly diagnosed in adults. AIE is primarily characterized by chronic diarrhea, malabsorption and villous atrophy in the small intestine. Diagnosis is primarily based on pathological findings. Most patients respond well to corticosteroid therapy. This report presents a patient of AIE with diarrhea as the main symptom. After developing steroid dependence, the patient was switched to ustekinumab and achieved satisfactory therapeutic outcomes.

0bjective:To explore the responsiveness and minimal clinical significance difference(MCID)of the Chinese version of the Chelsea critical care physical assessment tool(CPAx),the Perme Score intensive care unit mobil-ity score(Perme Score),and the intensive care unit(ICU)mobility scale(IMS)for patients in ICU during the early-stage rehabilitation,providing more comprehensive evidence support for clinical application of these scales.Method:It is a prospective observational study.The convenience sampling method was used to select 114 pa-tients in a ICU of a Tertiary Hospital in Shanghai from March 2021 to December 2021.Patients were as-sessed by Chinese version of CPAx,Perme Score,and IMS before the first rehabilitation treatment and within 24 hours before discharge from ICU.Likert five-scale was used to evaluate the overall changes in health sta-tus of the patients after the last rehabilitation.Responsiveness includes both internal responsiveness and exter-nal responsiveness.Internal responsiveness was determined by pair t-test,effect size(ES)and standardized re-sponse mean(SRM);external responsiveness was assessed by using Spearman correlation coefficient.MCID was calculated by integrating the estimates from the distribution-based methods and the anchor-based methods.Result:Internal responsiveness outcomes indicated that there was significant difference between the score of CPAx,Perme Score and IMS before and after rehabilitation(P＜0.05),with ES of 1.03,1.09 and 1.14,and SRM of 1.75,1.52 and 1.73,respectively.The results showed that the scale had good internal responsiveness and could sensitively reflect the changes of patients'condition.External responsiveness outcoms showed that Spearman correlation coefficients of CPAx,Perme Score and IMS with global rating of change(GRC)were 0.67,0.50 and 0.30,respectively(P＜0.01),indicating that apart from IMS,the other scales had good external reactivity,and could reflect the changes of patients'self-perception during the rehabilitation process.The MC-ID of CPAx scale with ES as the intermediate index is 5.66,SEM is 5.48,self-therapeutic effects is 8.73.The MCID of Perme Score with ES is 2.43,SEM is 3.64,self-therapeutic effects is 5.00.The MCID of IMS scale with ES is 1.28,SEM is 2.01,self-therapeutic effects is 2.43.Conclusion:Except for the lack of external responsiveness of IMS,the other Chinese version scales had good internal and external responsiveness in early-stage rehabilitation of ICU patients.Combined with the litera-ture review and the actual situation of using the scale in the study,the mean values of distribution method and criterion method were taken to preliminarily determine that the MCID of Chinese version of CPAx,Perme Score and IMS in ICU early rehabilitation were 6.62,3.69 and 1.90,respectively.
