Objective To explore the relationship between systemic immune-inflammation index(SII),red blood cell distribution width(RDW),25-hydroxy-vitamin-D[25(OH)D]levels and frailty index in elderly pa-tients with type 2 diabetes mellitus(T2DM).Methods A total of 197 elderly patients with T2DM admitted to the hospital from March 2023 to March 2024 were collected as the research subjects.The patients were divided into the frailty group(106 cases)and the non-frailty group(91 cases)according to the scores of the clinical frailty scale.The clinical data and the levels of SII,RDW and 25(OH)D of the two groups were compared.Pearson correlation analysis was used to analyze the correlations between the levels of SII,RDW and 25(OH)D and the frailty index of elderly patients with T2DM.Logistic regression was used to analyze the influencing factors of frailty in elderly patients with T2DM.Results Compared with the non-frailty group,the proportion of women,the history of falls within 1 year,and the age of the frailty group increased,while the body mass in-dex and the proportion of men decreased,and the differences were statistically significant(P＜0.05).The SII and RDW levels in the non-frailty group were lower than those in the frailty group,and the 25(OH)D level was higher than that in the frailty group,and the differences were statistically significant(P＜0.05).Pearson correlation analysis showed that SII and RDW levels were positively correlated with frailty index,and 25(OH)D level was negatively correlated with frailty index in elderly T2DM patients(P＜0.05).Logistic regression analysis showed that female,age ≥ 74.25 years old,SII≥ 938.36,RDW≥ 15.19％,and 25(OH)D≥48.42 nmol/L were independent risk factors for frailty in elderly T2DM patients(P＜0.05).Conclusion The levels of SII,RDW and 25(OH)D in elderly patients with T2DM are related to the frailty index.

Objective To analyze the morphological alterations of corpus callosum in children with spastic cerebral palsy(SCP)using three-dimensional magnetization prepared rapid acquisition gradient echo(3D-MPRAGE)technology and to investigate the correlation between morphological indexes and gross motor function.Methods Sagittal T1WI 3D-MPRAGE data was collected from 136 children with SCP(SCP group)and 132 age-and gender-matched healthy controls(HC)(HC group),and the gross motor function measure-88(GMFM-88)was applied to assess the gross motor function.Independent sample t-test was used to compare the corpus callosum surface area,volume,maximum anterior-posterior diameter,median sagittal area(total area and area of Ⅰ-Ⅴ zone)between the two groups.Partial correlation analysis was performed to calculate the correlation between morphological indexes of the corpus callosum and GMFM-88 with age as a covariate.Results Children under 3 years old,the corpus callosum surface area of the SCP group(3 914.51 mm2±1 207.97 mm2)was lower than that of the HC group(5 725.51 mm2±1 412.66 mm2).The volume of the corpus callosum(6 108.46 mm3±2 803.97 mm3)in the SCP group was lower than that of the HC group(11 297.96 mm3±4 109.02 mm3).Also,the maximum anterior-posterior diameter of the corpus callosum in the SCP group(53.40 mm±6.31 mm)was lower than that of the HC group(57.74 mm±6.04 mm)(all P<0.05).Children over 3 years old,the corpus callosum surface area of the SCP group(4 970.06 mm2±1 191.31 mm2)was lower than that of the HC group(6 372.55 mm2±1 445.59 mm2).The volume of the corpus callosum(8 330.20 mm3±2 888.20 mm3)in the SCP group was lower than that of the HC group(13 599.82 mm3±3 429.81 mm3)(all P<0.05).Partial correlation analysis showed significant correlation between corpus callosum volume,median sagittal area and gross motor score(P<0.01)with age as a covari-ate.Conclusion The 3D-MPRAGE technology can be useful for the comprehensive assessment of morphological alterations of the corpus callosum in SCP.The corpus callosum volume,and median sagittal area may become neuroimaging references for the assess-ment of motor development in cerebral palsy(CP).

Objectives:To explore the clinical characteristics of children with adenoid hypertrophy (AH) and laryngopharyngeal reflux (LPR) by detecting the expression of pepsin in adenoids as a standard for AH with LPR.Methods:A total of 190 children who were admitted for surgical treatment due to AH were included in the study. The main clinical symptoms of the patients were recorded, and the degree of adenoid hypertrophy was evaluated. Before the surgery, Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) were used to evaluate the reflux symptoms. After the surgery, pepsin immunohistochemical staining was performed on the adenoid tissue, and according to the staining results, the patients were divided into study group (pepsin staining positive) and control group (pepsin staining negative). SPSS 19.0 software was used for statistical analysis. Quantitative data conforming to normal distribution between the two groups were tested by two-independent sample t test, and quantitative data with skewed distribution were tested by Mann-Whitney U test. Results:The positive rate of pepsin staining in the 190 AH patients was 78.4% (149/190). The study group had higher levels of preoperative symptoms such as erythema and/or congestion of the pharynx(2.1±0.7 vs. 1.8±0.6, t=2.23), vocal cord edema[1.0(0, 1.0) vs. 1.0(0, 1.0), Z=2.00], diffuse laryngeal edema[0(0, 1.0) vs. 0(0, 0), Z=2.48], posterior commissure hypertrophy[(1.4±0.6 vs. 1.1±0.5), t=2.63], and a higher total score on the RFS scale than the control group(6.2±2.7 vs. 5.0±2.6, t=2.47), with statistical differences ( P<0.05). The sensitivity and specificity of RFS score in diagnosing AH with LPR were 24.8% and 80.5%, respectively. When RFS>5 was used as the positive threshold, the sensitivity and specificity of RFS score in diagnosing AH with LPR were 61.1% and 58.5%, respectively. There was a statistical difference in the number of positive cases of RFS score between the study group and the control group(91 vs. 17, χ2=5.04, P=0.032). Conclusions:LPR is common in AH children. Children with AH and LPR have specific performance in electronic laryngoscopy, such as erythema with edema in the pharynx, posterior commissure hypertrophy, and vocal cord edema.

Background::Immunoglobulin G4-related disease (IgG4-RD) is a recently recognized immune-mediated disorder that can affect almost any organ in the human body. IgG4-RD can be categorized into proliferative and fibrotic subtypes based on patients’ clinicopathological characteristics. This study aimed to compare the clinical manifestations, laboratory findings, and treatment outcomes of IgG4-RD among different subtypes.Methods::We prospectively enrolled 622 patients with newly diagnosed IgG4-RD at Peking Union Medical College Hospital from March 2011 to August 2021. The patients were divided into three groups according to their clinicopathological characteristics: proliferative, fibrotic, and mixed subtypes. We compared demographic features, clinical manifestations, organ involvement, laboratory tests, and treatment agents across three subtypes. We then assessed the differences in treatment outcomes among 448 patients receiving glucocorticoids alone or in combination with immunosuppressants. Moreover, risk factors of relapse were revealed by applying the univariate and multivariate Cox regression analysis.Results::We classified the 622 patients into three groups consisting of 470 proliferative patients, 55 fibrotic patients, and 97 mixed patients, respectively. We found that gender distribution, age, disease duration, and frequency of allergy history were significantly different among subgroups. In terms of organ involvement, submandibular and lacrimal glands were frequently involved in the proliferative subtype, while retroperitoneum was the most commonly involved site in both fibrotic subtype and mixed subtype. The comparison of laboratory tests revealed that eosinophils ( P = 0.010), total IgE ( P = 0.006), high-sensitivity C-reactive protein ( P <0.001), erythrocyte sedimentation rate ( P <0.001), complement C4 ( P <0.001), IgG ( P = 0.001), IgG1 (P <0.001), IgG4 (P <0.001), and IgA ( P <0.001), at baseline were significantly different among three subtypes. Compared with proliferative and mixed subtypes, the fibrotic subtype showed the lowest rate of relapse (log-rank P = 0.014). Conclusions::Our study revealed the differences in demographic characteristics, clinical manifestations, organ involvement, laboratory tests, treatment agents, and outcomes across proliferative, fibrotic, and mixed subtypes in the retrospective cohort study. Given significant differences in relapse-free survival among the three subtypes, treatment regimens, and follow-up frequency should be considered separately according to different subtypes.Trial Registration::ClinicalTrials. gov, NCT01670695.

Objective To assess the impact of intravenous esketamine administered prior to car-diopulmonary bypass(CPB)initiation on ventricular function and internal carotid artery blood flow in pa-tients undergoing heart valve replacement surgery.Methods Sixty patients underwent elective CPB heart valve replacement,38 males and 22 females,aged 18-75 years,BMI 18.5-30.0 kg/m2,ASA physical status Ⅱ or Ⅲ,NYHA cardiac function classification Ⅰ-Ⅲ,and a left ventricular ejection fraction(LVEF)of≥45％,were selected.The patients were randomly divided into two groups:esketamine group(group E)and normal saline group(group C),30 patients in each group.Total intravenous anesthesia was used during the operation.Following the initiation of CPB,group E received an intravenous infusion of es-ketamine at a rate of 0.5 mg·kg-1·h-1 until the conclusion of the procedure,while group C received an equivalent volume of normal saline concurrently at the same rate.HR,MAP,CVP,and cardiac output index(CI)were recorded before anesthesia induction,during skin resection,and within 60 minutes after stopping CPB.LVEF,left ventricular global longitudinal strain(GLS),global longitudinal time-to-peak strain standard deviation(GLTSD),global circumferential strain(GCS),global circumferential time-to-peak strain standard deviation(GCTSD),right ventricular ejection fraction(RVEF),right ventricular GLS,and GLTSD were obtained during skin resection,within 40 minutes of CPB,and 60 minutes after stopping CPB.rScO2,BIS,concentrations of Hb and lactic acid(Lac),peak systolic flow velocity(SPV),quantity of flow-internal carotid artery(Q-ICA),and blood flow resistance index(RI)were recorded before anesthesia induction,during skin resection,within 40 minutes of CPB,and within 60 minutes after stopping CPB.Concentrations of cardiac troponin Ⅰ(cTnⅠ),alanine aminotransferase(ALT),creatinine(Cr),and neuron-specific enolase(NSE)were recorded before anesthesia induction and 6 hours after operation.Spon-taneous resuscitation after CPB,postoperative extubation time,duration of ICU stay,total hospital stay,in-cidence of adverse cardiac events,and 30-day postoperative mortality were recorded.Results Compared with group C,group E exhibited a significant increase in CI within 60 minutes after stopping CPB(P＜0.05).The LVEF,RVEF,and right ventricular GLS demonstrated significant increases within 60 minutes after stopping CPB in group E compared with group C(P＜0.05).The left ventricular GLS and left ven-tricular GCTSD displayed significant increases 30 minutes after stopping CPB in group E compared with group C.The RI exhibited a significant increase within 40 minutes of CPB in group E compared with group C(P＜0.05).There were no significant differences in cTnⅠ,ALT,Cr,NSE,spontaneous resuscitation affter CPB,postoperative extubation time,duration of ICU stay,total hospital stay,incidence of cardiac adverse events,and 30-day postoperative mortality between the two groups.Conclusion Administration of esket-amine following the onset of CPB in patients undergoing cardiac surgery demonstrates a significant elevation in CI post-CPB cessation.Furthermore,it may augment ventricular longitudinal strain,thereby enhancing myocardial contraction,leading to increased postoperative ventricular ejection fraction,and sustaining hemo-dynamic stability.

Objective To analyze the CT imaging features of renal parenchymal urothelial carcinoma and other renal infiltrative lesions,and to improve the diagnostic and differential diagnostic accuracy of renal parenchymal urothelial carcinoma.Methods The clinical and imaging data from 60 patients with renal infiltrative lesions involving both the renal pelvis and renal parenchyma confirmed by pathology were collected,including 27 cases of renal parenchymal urothelial carcinoma,20 cases of renal papillary cell carcinoma,and 13 cases of renal lymphoma.All patients underwent plain and three-phase enhanced scans.Clinical manifestations and imaging fea-tures were analyzed,and the tumor/cortex CT ratio was measured on plain and three-phase enhanced scans,and statistically ana-lyzed.Results The renal contour of some patients with renal papillary cell carcinoma was altered and locally protruded beyond the contour,while the remaining patients had a normal renal morphology,with involvement of either a renal segment or the entire kid-ney,and unclear cortex-medulla differentiation.All three types of tumors showed mild to moderate progressive enhancement.The tumor/cortex CT ratio on plain scan had no statistical significance among the three groups(P＞0.05),while the tumor/cortex CT ratio on three-phase enhanced scan showed statistical significance(P＜0.05).Conclusion There are differences in imaging manifes-tations between renal parenchymal urothelial carcinoma and other renal infiltrative lesions,with significant differences in the phase of peak enhancement.

Objective To investigate the effect of early postoperative activities on rehabilitation and discharge in hepatocellular carcinoma patients with portal hypertension.Methods A total of 423 patients who underwent surgical treatment for hepatocellular carcinoma with portal hypertension in The Third Affiliated Hospital of Naval Medical University from June 2019 to June 2021 were collected as research objects.There were 348 patients without early postoperative activity and 75 patients with early postoperative activity.The impacts of preoperative factors(age,gender,smoking history,etc.)and intraoperative factors(intraoperative hepatic portal block,perioperative blood transfusion,and tumor size)on postoperative recovery of patients were analyzed.In order to reduce the selection bias,75 patients were chosen from 348 patients without early postoperative activity by propensity score matching and taken as non-early activity group.Early postoperative complications,gastrointestinal function recovery(including first ventilation time,abdominal distension,and diarrhea),postoperative hospital stay,and total hospital stay were compared between non-early activity group and early activity group before and after propensity score matching.Results There was no significant difference in the incidences of serious postoperative complications,postoperative diarrhea,or total length of hospital stay between non-early activity group and early activity group before and after propensity score matching(P>0.05).But there were significant differences in the incidences of first ventilation time,postoperative abdominal distension,and postoperative hospital stay between the two groups(P<0.05).Conclusion Early postoperative activities can accelerate the recovery of gastrointestinal function in portal hypertension patients undergoing hepatectomy,promote the intake and absorption of nutrients,facilitate the recovery of postoperative liver function,shorten the postoperative hospital stay,and promote the early recovery of patients.

OBJECTIVES: This study evaluated the association between obesity and glaucoma in middle-aged and older people. A population-based retrospective cohort study was conducted using data from the China Health and Retirement Longitudinal Study. METHODS: Glaucoma was assessed via self-reports. Multivariate logistic regression analysis and a Cox proportional hazards model were used to assess the relationship between obesity and glaucoma risk. RESULTS: Older males living in urban areas who were single, smokers, and non-drinkers were found to have a significantly higher incidence of glaucoma (all p<0.05). Diabetes, hypertension, and kidney disease were also associated with higher glaucoma risk, while dyslipidemia was associated with lower risk (all p<0.05). After the model was adjusted for demographic, socioeconomic, and health-related variables, obesity was significantly associated with a 10.2% decrease in glaucoma risk according to the Cox proportional hazards model (hazard ratio, 0.90; 95% confidence interval [CI], 0.83 to 0.97) and an 11.8% risk reduction in the multivariate logistic regression analysis (odds ratio, 0.88; 95% CI, 0.80 to 0.97). A further subgroup analysis showed that obesity was associated with a reduced risk of glaucoma in people living in rural areas, in smokers, and in those with kidney disease (all p<0.05). Obesity also reduced glaucoma risk in people with diabetes, hypertension, or dyslipidemia more than in healthy controls (all p<0.05). CONCLUSIONS This cohort study suggests that obesity was associated with a reduced risk of glaucoma, especially in rural residents, smokers, and people with kidney disease. Obesity exerted a stronger protective effect in people with diabetes, hypertension, or dyslipidemia than in healthy people.

The finally remote health management program based on dynamic blood glucose monitoring system for elderly patients with diabetes and sarcopenia included 3 first level indicators (remote health management service content, remote health management system, service project description), 11 second level indicators and 25 third level indicators. Conclusions:The remote health management program based on dynamic blood glucose monitoring system for elderly patients with diabetes and sarcopenia is scientific, practical and applicable, and has practical significance for clinical nursing.

【Objective】 To investigate the association of normal weight obesity （NWO） with carotid atherosclerosis （CAS） and peripheral arterial stiffness （PAS） in persons received physical examination. 【Methods】 A total of 1 894 people with normal BMI （18.5-23.9 kg/m²） were consecutively enrolled for this study. All these people had completed body fat measurement， carotid artery ultrasound examination and peripheral arterial stiffness detection. Then they were divided into control group， CAS group， PAS group， and CAS + PAS group according to the test results mentioned above. Clinical data were compared between different groups to assess the baseline situation. Besides， Multivariate Logistic regression analysis was performed to determine independent risk factors for atherosclerosis. 【Results】 The proportion of NWO in CAS group， PAS group， and CAS + PAS group was significantly higher than that in normal group （P<0.05）. Univariate analysis results showed that NWO was correlated with greater risks of both CAS and PAS （P<0.05）. However， multiple factors analysis suggested that NWO was not associated with PAS， but with CAS （OR=1.286， 95% CI： 1.032-1.603， P<0.05）. 【Conclusion】 NWO is closely related to the occurrence of CAS and may be an independent risk factor for CAS. Attention should be paid to the body fat mass of the NWO population. Early intervention is needed to prevent the occurrence of CAS in these people.
