ObjectiveTo clarify the application value of nutritional scoring in patients with sepsis and explore the impact of the modified Nutritional Risk in Critically Ill （mNUTRIC） score on the in-hospital fatality of sepsis patients in the emergency intensive care unit （EICU）. MethodsA retrospective analysis was conducted on the clinical data and laboratory examination results of 436 sepsis patients treated in the EICU of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2021 to May 2024. The patients were divided into survival group （298 cases） and death group （138 cases） according to whether they died or not during hospital treatment， and then compared the two groups’ data. Logistic multi-factor regression analysis was used to analyze the risk factors for in-hospital death and the ROC curve to evaluate the predictive value of each risk factor for the prognosis of sepsis patients. ResultsThe death group exhibited higher Acute Physiology and Chronic Health EvaluationⅡ（APACHE Ⅱ） score， Nutritional Risk Screening 2002 （NRS 2002） score， mNUTRIC score， Sequential Organ Failure Assessment （SOFA） score， Padua Prediction Score for Venous Thromboembolism， the proportions of chronic kidney failure and pneumonia patients， C-reactive protein （CRP） level， lactate concentration and neutrophil count， but lower prognostic nutritional index， cholinesterase level， cholinesterase-albumin ratio and lymphocyte count than the survival group， with statistical significance （all P<0.05）. Logistic regression analysis revealed that the mNUTRIC score ［OR=1.254， 95%CI （1.109，1.417）］， CRP ［OR=1.004， 95%CI （1，1.007）］， and pneumonia ［OR=1.82， 95%CI （1.017， 3.257）］ were independent risk factors for in-hospital death in sepsis patients. ROC curve analysis showed that the area under the curve （AUC） of the mNUTRIC score for predicting in-hospital death in sepsis patients was 0.683 ［95%CI （0.623，0.742）］， with a sensitivity of 83% and a specificity of 49.3%. The AUC for CRP and pneumonia were 0.602 ［95%CI （0.533， 0.671）］， and 0.582 ［95%CI （0.516，0.647）］. ConclusionThe mNUTRIC score is an independent predictive indicator for in-hospital death in sepsis patients in the EICU.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To explore the correlation between the rs290487 and rs7903146 single-nucleotide polymorphism(SNP)of TCF7L2 gene and the occurrence of diabetic kidney disease(DKD)in type 2 diabetes mellitus(T2DM)population in Hebei region.Methods Epidemiological and clinical data as well as SNP data at TCF7L2 rs290487 and rs7903146 sites were collected from 317 non DKD patients and 302 DKD patients.The correlation between SNP at rs290487 and rs7903146 sites and DKD was analyzed through a case-control design.Results The genotype frequency distribution at the rs290487 and rs7903146 loci of the two TCF7L2 genes conforms to the Hardy-Weinberg genetic balance(P>0.05),and the allele frequency distribution conforms to the Hardy-Weinberg genetic balance(P>0.05).Single factor logistic regression analysis of genetic models for different genotypes at rs290487 locus showed that the risk of DKD in TC+CC genotype carriers was 2.772 times that of TT genotype carriers in the dominant model.Multivariate logistic regression analysis of genetic models for different genotypes at rs290487 locus showed that the risk of DKD in TC+CC genotype carriers was 2.837 times that of TT genotype carriers.Conclusions TC and CC genotypes at rs290487 sites of TCF7L2 gene are risk factors for DKD,and gene mutation at rs290487 sites may be associated with DKD in T2DM population in Hebei.

Objective:To identify the differentially expressed proteins that caused hippocampal damage after liver ischemia-reperfusion (I/R) in rats.Methods:Eighteen clean-grade healthy juvenile male Sprague-Dawley rats, aged 2 weeks, weighing 20-30 g, were divided into 2 groups ( n=9 each) using a random number table method: sham operation group (S group) and liver I/R group (IR group). A rat model of liver I/R injury was prepared by restoring perfusion after 1 h of liver ischemia. The rats were sacrificed after being anesthetized at day 3 of reperfusion, and the hippocampal tissue was isolated and analyzed to obtain gene expression profiles. Differentially expressed genes were identified using the R software, and further protein interaction networks were constructed through Cytoscape and Kyoto Encyclopedia Genes and Genomes pathway analysis to determine the differentially expressed proteins. Quantitative real-time polymerase chain reaction and Western blot were used for validation. Results:A total of 45 differentially expressed proteins were identified by the proteomic analysis of hippocampal tissues, including 36 significantly up-regulated proteins and 9 significantly down-regulated proteins. The proteins with significant expression related to injury were identified from the PPI network complex using the CytoHubBA plug-in cystscape: Ras-related C3 botulinum toxin substrate (RAC2), HRAS, phosphatidylinositol-3-kinase inhibitor phosphatase and tensin homologue (PTEN), and N-methyl-D-aspartate ionotropic glutamate receptor 2b (GRIN2b). The results of quantitative real-time polymerase chain reaction and Western blot showed that the expression of RAC2, HRAS, PTEN, and GRIN2b in the hippocampal tissue was significantly up-regulated in IR group compared with S group ( P<0.05). The results of Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that differentially expressed proteins were significantly enriched in the expression of PD-L1 and its checkpoint pathway, long-term potentiation, and regulation of the Wnt signaling pathway in cancer. Conclusions:The mechanism by which liver I/R induces hippocampal injury may be related to the up-regulation of the expression of RAC2, HRAS, PTEN and GRIN2b in rats.

Objective:To analyze the significance of systemic immune inflammatory index (SII) combined with neutrophil lymphocyte ratio (NLR) in the treatment of advanced gastric cancer with PD-1/PD-L1 inhibitors.Methods:The clinical data of 90 patients with stage Ⅳ gastric adenocarcinoma who received immunotherapy from January 2020 to January 2023 were retrospectively analyzed, including 70 males and 20 females, aged from 36 to 80 years, with an average age of (53.76±15.58) years. The clinicopathological features and follow-up data were collected. SPSS 26.0 software was used to conduct statistical analysis. The critical values of NLR, SII, PLR and MLR were calculated, and the overall survival (OS) and progression free survival (PFS) of patients with different levels of markers were analyzed. The independent predictive factors of PFS and OS were determined, and the predictive value of risk factors for PFS and OS in patients with gastric cancer was evaluated.Results:The median follow-up time of all patients was 27.3 months, and the median PFS and OS were 10.0 months and 17.7 months, respectively. The area under the curve (AUC) of NLR and SII for predicting PFS and OS were>0.7, the critical values NLR were 4.75 and 3.85, and SII were 1154.67 and 887.90, respectively. PFS and OS in patients with high NLR, high MLR, high PLR and high SII were lower than those in patients with low levels. ECoG PS≥ 1, high NLR and high SII were independent influencing factors of disease progression or death. The AUC of the combination of NLR, ECoG PS and SII was 0.761, which was higher than that of any single factor. The fewer the number of risk factors, the longer the PFS and OS.Conclusions:NLR and SII are effective predictors of PFS and OS in patients with advanced gastric cancer receiving immunotherapy. Pre treatment detection of NLR and SII can provide reliable guidance for immunotherapy of advanced gastric cancer.

Objective:To investigate the association of time in range with metabolic associated fatty liver disease(MAFLD) and advanced liver fibrosis in patients with type 2 diabetes.Methods:This study was a retrospective study. A total of 494 type 2 diabetic patients were recruited in the Department of Endocrinololgy of Henan Provincial People′s Hospital from November 2019 to April 2022. Time in range(TIR) was calculated with continuous glucose monitoring data. Abdominal ultrasound scan was used to diagnose fatty liver. Liver stiffness measurement(LSM) by transient elastography was used to evaluate liver fibrosis. Pearson and multivariate linear regression analysis was used to evaluate the association between TIR and LSM. Multivariate logistic regression analysis was used to analyze the association of TIR with risk of MAFLD and advanced liver fibrosis.Results:Pearson correlation analysis showed that LSM was negatively correlated with TIR( r=-0.86, P<0.001) and was positively correlated with homeostasis model assessment for insulin resistance(HOMA-IR; r=0.48, P<0.001). After adjusting for confounding factors, multivariate linear regression analysis showed that TIR significantly negatively predicted LSM( β=-0.75, P<0.001), and HOMA-IR significantly positively predicted LSM( β=0.21, P=0.025). After adjusting for confounding factors, logistic regression analysis showed that compared with TIR Q4 patients, TIR Q1 patients had an increased risk of MAFLD( OR=1.96, 95% CI 1.07-3.62, P=0.027), advanced liver fibrosis( OR=3.82, 95% CI 1.17-12.50, P=0.027), and HOMA-IR was an independent risk factor for MAFLD( OR=1.22, 95% CI 1.04-1.43, P=0.005) and advanced liver fibrosis( OR=1.26, 95% CI 1.03-1.54, P=0.025). Conclusions:TIR and insulin resistance are independent risk factors for MAFLD and advanced liver fibrosis in patients with type 2 diabetes. TIR has a significant predictive value for MAFLD and advanced liver fibrosis.

Objective:To preliminarily explore the long-term improvement of low-frequency deep brain stimulation (DBS) on the nucleus basalis of Meynert (NBM) in cognitive disorders, neuropsychiatric symptoms and sleep disorders of patients with early-onset severe Alzheimer's disease (AD).Methods:A retrospective study was performed; 18 patients with early-onset severe AD admitted to Department of Neurosurgery, First Medical Center of PLA General Hospital from January 2016 to December 2022 were included. These patients were divided into NBM-DBS group and control group according to different treatments; 6 patients received low-frequency NBM-DBS on basis of conservative treatments; 12 patients accepted conservative treatments. Changes in Brief Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Neuropsychiatric Inventory (NPI), Hamilton Depression Rating Scale (HAMD), Becker-Lavanson Mania Scale (BRMS), Pittsburgh Sleep Quality Index (PSQI), and Zarit Caregiver Burden Interview (ZBI) were observed before treatment and 1 year after follow up.Results:MMSE and MoCA scores 1 year after follow up obviously reduced compared with those before treatment in both NBM-DBS and control patients; MMSE and MoCA scores in NBM-DBS patients showed no significant differences between 1 year after follow up and before treatment ( P>0.05), while significant differences were noted in the control group between 1 year after follow-up and before treatment ( P<0.05); and no significant differences in MMSE and MoCA scores were noted between the 2 groups 1 year after follow up ( P>0.05). NPI, HAMD, BRMS and ZBI scores in the NBM-DBS group 1 year after follow up were significantly different compared with those before treatment ( P<0.05); no significant differences were noted in NPI, HAMD and ZBI scores in the control group between 1 year after follow up and before treatment ( P>0.05), while significant difference was noted in BRMS scores ( P<0.05); significant differences in NPI, HAMD, BRMS and ZBI scores were noted between the 2 groups 1 year after follow up ( P<0.05). Conclusion:Low-frequency NBM-DBS is not only effective in improving cognitive disorders, but also effective in improving neuropsychiatric symptoms and sleep disorders, as well as reducing caregiver burden in patients with early-onset severe AD.

BACKGROUND:Diabetic foot patients with wound infections constitute a large patient population,and there is currently no satisfactory treatment approach. OBJECTIVE:To investigate the clinical efficacy of a modified tibial cortex transverse transport combined with antibiotic-loaded bone cement for treating refractory diabetic foot ulcers. METHODS:A total of 46 diabetic foot ulcers patients,27 males and 19 females,with an average age of 64.37 years,were selected from Beijing Chaoyang Hospital,Capital Medical University and Beijing Chaoyang Integrative Medicine Rescue and First Aid Hospital from January 2020 to January 2023.All of them underwent the modified tibial cortex transverse transport combined with antibiotic-loaded bone cement treatment.Ankle-brachial index,WIFi(Wound/Ischemia/Foot infection)classification,pain visual analog scale score,and ulcer area were recorded before and 3 months after surgery. RESULTS AND CONCLUSION:(1)The mean ulcer healing time for the 46 patients was(58.07±24.82)days.At 3 months postoperatively,there were significant improvements in ankle-brachial index,pain visual analog scale score,ulcer area,and WIFi classification in 46 patients,as compared to the preoperative values,with statistically significant differences(P<0.05).Two patients experienced pin-tract infections,without infection or ulcer recurrence during the follow-up period.(2)These findings indicate that the modified tibial cortex transverse transport combined with antibiotic-loaded bone cement effectively alleviates patients'pain,improves lower limb circulation,controls infections,and promotes ulcer healing.

Objective To explore the effects of dexmedetomidine combined with desflurane anesthesia on cerebral oxygen metabolism,sedation depth and cerebral function in liver cancer patients undergoing partial hepatic lobectomy.Methods A total of 30 liver cancer patients undergoing partial hepatic lobectomy at the Affiliated Cancer Hospital of Zhengzhou University from March to September 2022 were selected as the research subjects,they were divided into control group(n=15)and observation group(n=15)according to different anesthesia methods.Patients in both groups underwent partial open hepatectomy,and they were given the same anesthesia induction method.The patients in the control group received desflurane for anesthesia mainte-nance,while patients in the observation group received dexmedetomidine combined with desflurane for anesthesia maintenance.The anesthesia recovery indexes including the postoperative recovery time,recovery time of spontaneous breathing,eye-opening time of patients between the two groups were compared.The arterial oxygen saturation(SaO2),cervical vein oxygen saturation(SjvO2),arterial partial pressure of oxygen(PaO2)and partial pressure of venous oxygen of patients were detected by blood gas analyzer before anesthesia induction(T0),at the completion of anesthesia induction(T,),at 10 minutes after hepatic portal occlusion(T2),after hepatic lobectomy(T3)and after surgery(T4),and arterio-venous oxygen content difference(AVDO2)and cerebral oxygen extraction rate(CEO2)were calculated.The sedation depth of patients was evaluated by bispectral index(BIS)and patient state index(PSI)at T0,T1,T2,T3 and T4.The cerebral function of patients was evaluated by the Glasgow-Pittsburgh cerebral performance category scale at 3 months after surgery.The incidence of postoperative adverse reactions of patients between the two groups was compared.Results The postoperative recovery time,recovery time of sponta-neous breathing and eye-opening time of patients in the observation group were significantly shorter than those in the control group(P＜0.05).There was no significant difference in SaO2 of patients between the two groups at different time points(P＞0.05).At T2 and T3,SjvO2,AVDO2 and CEO2 of patients in the observation group were significantly lower than those in the control group(P＜0.05),but there was no significant difference in SjvO2,AVDO2 and CEO2 of patients between the two groups at the other time points(P＞0.05).At T2,T3 and T4,BIS and PSI of patients in the observation group were significantly lower than those in the control group(P＜0.05),but there was no significant difference in BIS and PSI of patients between the two groups at T0 and T1(P＞0.05).In the control group,there were 11 patients with postoperative brain function in grade 1,3 patients in grade Ⅱ and 1 patient in grade Ⅲ;in the observation group,there were 12 patients in grade Ⅰ and 3 patients in gradeⅡ.There was no significant difference in postoperative grading of brain function between the two groups(x2=1.044,P＞0.05).There was no significant difference in the total incidence of postoperative adverse reactions between the control group and observation group[20.00％(3/15)vs 26.67％(4/15),x2=0.186,P＞0.05].Conclusion Dexmedetomidine combined with desflurane anesthesia can shorten anesthesia recovery time,improve anesthesia depth and reduce cerebral oxygen metabolism in patients undergoing liver cancer surgery,which has no effect on cerebral function,showing good safety.
