With advances in imaging and the growing emphasis on nephron preservation, partial nephrectomy has become central in the management of T1 renal tumors and has gradually been extended to complex renal masses, where surgical challenges are greater.This article reviews the current status, key technical advances, and clinical application strategies of minimally invasive partial nephrectomy for complex renal tumors.It compares the suitability and advantages of laparoscopic and robot-assisted approaches across different levels of tumor complexity, and summarizes the value of three-dimensional reconstruction, precise selective vascular control, and intraoperative navigation in improving surgical safety and controllability. It elaborates on the management pathways and technical strategies for typical scenarios such as renal hilar lesions, completely intrarenal tumors, cystic tumors, and multifocal tumors, and summarizes operative techniques and perioperative risk-control considerations for high-risk cases, including solitary kidneys, T2 or higher stage tumors, tumors with local invasion of the renal pelvis, and those complicated with vascular tumor thrombus.The article also briefly discusses controversies regarding indication boundaries and the balance between functional preservation and oncologic safety, and highlights the trend toward a standardized, reproducible precision surgery paradigm supported by intelligent planning and quality-control systems.

Objective:To explore the longitudinal predictive relationship between self-neglect and frailty among older adults.Methods:Data were drawn from the Chinese Longitudinal Healthy Longevity Survey conducted in 2011 (T1), 2014 (T2), and 2018 (T3). A total of 1 495 older adults aged≥65 years at T1 who participated in three consecutive surveys and had no missing key variables were included. General demographic information, self-neglect scores, and frailty status were extracted. Spearman correlation analysis was used to examine the association between self-neglect and frailty. Cross-lagged analysis was employed to investigate the potential causal relationship between the two variables.Results:The self-neglect scores for 1 495 older adults at T1, T2, and T3 were (2.84±1.39), (2.47±1.30), and (2.41±1.20), respectively, showing a declining trend. The frailty scores at T1, T2, and T3 were 0 (0, 1.00), 0 (0, 2.00), and 1.00 (0, 2.00), respectively, indicating an increasing trend. Cross-lagged analysis revealed that self-neglect at T1 positively predicted frailty at T2 (β=0.076, P=0.004). Frailty at both T1 and T2 positively predicted self-neglect at T2 (β=0.057, P=0.044) and T3 (β=0.058, P=0.029), respectively. Conclusions:Frailty among older adults positively predicts self-neglect, and self-neglect also has a certain predictive effect on frailty. Medical staff should strengthen early screening and intervention for frailty in older adults to delay the occurrence and progression of self-neglect.

Aim To investigate the association of triglyceride-glucose(TyG)index with microvascular obstruction(MVO)after percutaneous coronary intervention(PCI)in patients with ST-segment elevated myocardial infarction(STEMI).Methods Individual patient-data were pooled from 310 patients with STEMI underwent emergency PCI in Nanjing Drum Tower Hospital,the Affiliated Hospital of Nanjing University Medical School from June 2018 to June 2021 for a prospective analysis.A week following the operation,cardiac magnetic resonance imaging was used to evaluate the MVO region and the patients were divided into two groups based on whether MVO occured after PCI:the MVO group(n=183)and the non-MVO group(n=127).The clinical data of the two groups were compared,and the linear relationship between TyG index and MVO was described using restricted cubic splines(RCS).Univariate and multivariate Logistic regression analysis were used to correct for confounding factors and identify independent risk factors for MVO occurrence.Results After adjustment for confounding factors,TyG index was an independent risk factor for MVO after emergency PCI in STEMI patients,and every 1-unit increased in TyG index,the risk of MVO increased by 1.24 times(OR=2.24,95％CI:1.07～4.71,P=0.033).The RCS curve analysis results showed that there was a linear re-lationship between the TyG index and the occurrence of MVO after emergency PCI(non-linear correlation test P=0.47).When the TyG index was greater than 9.5,the risk of MVO after emergency PCI significantly increased.Conclusion An increased TyG index is postively associated with the incidence of MVO in STEMI patients who have undergone PCI,and has clinical significantce for early prevention and risk stratification of MVO in STEMI patients.

Purpose To compare the clinical and cardiovascular magnetic resonance(CMR)characteristics of hypertrophic cardiomyopathy(HCM)with and without diabetes mellitus,and to investigate the effect of diabetes mellitus on left ventricular remodeling in HCM patients.Materials and Methods A total of 96 HCM patients diagnosed with CMR in Chengdu Fifth People's Hospital from January 2021 to March 2023,retrospectively.They were divided into HCM with diabetes mellitus group(n=22)and HCM without diabetes mellitus group(n=74)according to whether they had diabetes mellitus.The clinical baseline and CMR data of HCM patients were analyzed,and left ventricular function and strain were compared between the two groups.Results The HCM group with diabetes mellitus was observed to have a significantly higher left ventricular mass index compared to HCM without diabetes mellitus group[(1.33±0.50)g/ml vs.(1.10±0.23)g/ml;t=3.002,P=0.003],along with a significantly lower left ventricular global circumferential strain[-19.69(-21.82,-17.06)%vs.-16.33(-20.84,-13.86)%;Z=543.000,P<0.05]and global longitudinal strain[(-8.69±3.94)%vs.(-10.74±3.62)%;t=2.227,P<0.05)].Furthermore,diabetes mellitus was identified as an independent factor associated with an increased left ventricular mass index(β=0.330,P<0.05)by multivariate linear regression analysis.Conclusion In patients with HCM,diabetes mellitus is independently associated with left ventricular remodeling.The global circumferential strain and longitudinal strain of HCM patients with diabetes mellitus decreases significantly,suggesting that diabetes mellitus has a significant impact on left ventricular strain in HCM patients.

Objective:To explore the mediating effect of dyadic coping between perceived social support and family cohesion and adaptability and happiness in spouses of patients with post-stroke motor impairments.Methods:From December 2023 to May 2024, a total of 366 spouses of patients with post-stroke motor impairments who received treatment at the First Affiliated Hospital of Zhengzhou University were recruited as study participants. Data were collected using the general information, perceived social support scale, dyadic coping inventory, Chinese version of the family cohesion and adaptability scale(FACESⅡ-CV), and memorial University of Newfoundland scale of happiness. The AMOS 21.0 software was utilized to construct a structural equation model to examine the mediating effect of dyadic coping between perceived social support, family cohesion and adaptability and happiness.Results:The spouses of patients with post-stroke motor impairments reported overall scores for perceived social support (62.80±12.80), dyadic coping (117.07±20.78), family cohesion and adaptability (115.96±19.51), and happiness (22.27±7.29). Family cohesion and adaptability was positively correlated with dyadic coping and perceived social support ( r=0.614, 0.520, both P<0.01).Spousal happiness was positively correlated with dyadic coping and perceived social support ( r=0.296, 0.202, both P<0.01).The spouses recognized that perceived social support had a positive correlation with dyadic coping ( r=0.479, P<0.01).Dyadic coping played a partial mediating effect between perceived social support and family cohesion and adaptability as well as happiness, accounting for 32.41% (0.211/0.651) and 44.39% (0.190/0.428) of the total effect, respectively. Conclusion:Dyadic coping is the mediating variable of family cohesion, adaptability and happiness of spouses of patients with post-stroke motor impairments. Medical staff should try to construct a dyadic coping intervention plan to improve the dyadic coping level of spouses of patients with post-stroke motor impairments, so as to improve their family happiness index.
