Objective To explore the related risk factors of osteosarcopenia (OS) in elderly patients with type 2 diabetes mellitus (T2DM) and to evaluate their predictive value. Methods We selected 409 elderly patients with T2DM from our hospital between June 2021 and December 2024 as the study subjects, and divided them into an OS occurrence group and a non-occurrence group based on whether they were diagnosed with OS. Results Among the 409 elderly patients with T2DM included, 93 were diagnosed with OS, yielding a prevalence rate of 22.73%. Spearman correlation analysis revealed a significant association between lumbar spine BMD and T-scores with age, history of previous fractures, fasting plasma glucose (FPG), procollagen type I N-terminal propeptide (PINP), osteocalcin (OC), and 25-hydroxyvitamin D (25(OH)D). Gender (OR=0.193), Body Mass Index (BMI) (OR=0.254), history of previous fractures (OR=8.883), FPG (OR=0.543), Total Cholesterol (TC) (OR=3.684), High-Density Lipoprotein Cholesterol (HDL-C) (OR=86.024), PINP (OR=0.818), and OC (OR=0.526) are identified as influential factors for the occurrence of OS in elderly patients with T2DM. The combined prediction of these variables yields a sensitivity of 96.5%, a specificity of 97.8%, and an area under the curve (AUC) of 0.992 for the occurrence of OS in elderly patients with T2DM, indicating an excellent predictive performance. Conclusion The following factors—gender, BMI, history of previous fractures, FPG, TC, HDL-C, PINP, and OC—are influential in the occurrence of OS among elderly patients with T2DM. Formulating intervention measures based on these influencing factors can provide assistance in preventing and treating the occurrence of OS.

Modern cataract surgery has completely moved beyond the traditional vision-restoring model and has fully entered a new era of refractive cataract surgery(RCS)centered on precise refractive correction. Its core objective is to provide patients with personalized visual experiences characterized by full-range, clear, and comfortable vision. Currently, although diagnostic and therapeutic technologies for RCS are rapidly evolving, there remain many bottlenecks in the precise management of the entire perioperative process that urgently need to be addressed. Preoperatively, the measurement consistency among ocular biometry devices based on different detection principles remains poor, and systematic measurement errors cannot be completely eliminated. Moreover, the individualized selection of intraocular lenses(IOLs)relies heavily on surgeons' clinical experience, lacking a standardized quantitative decision-making framework, which makes it difficult to achieve precise personalized matching. Intraoperatively, the quality of continuous curvilinear capsulorhexis is affected by multiple factors such as ocular anatomical characteristics and surgical proficiency, and its stability cannot be reliably ensured. Various intelligent surgical navigation systems are compromised by intraoperative ocular conditions, and their clinical performance fails to meet theoretical expectations. At the postoperative stage, existing IOL optical designs and materials have inherent limitations. The longterm prevention and control of posterior capsule opacification(PCO)remains a core factor restricting patients' long-term high-quality visual outcomes. This article systematically reviews the precise diagnostic and therapeutic challenges and core bottlenecks across the preoperative, intraoperative, and postoperative stages of RCS. It further explores frontier technological directions—including cross-device error compensation models, artificial intelligence-assisted decision-making, preoperative VR-based visual simulation, and the construction of intelligent surgical ecosystem platforms—to delineate targeted solutions and optimization pathways. This review aims to provide references and insights for the standardized clinical implementation, technological innovation, and future research endeavors in precision diagnosis and treatment of RCS.

Phacoemulsification represents the mainstream, efficient, and safe surgical modality for cataract treatment, and continuous technological advances have further improved the safety profile of this procedure in ordinary patients. However, patients with high myopia feature inherent anatomical abnormalities of the eyeball, leading to a fundamental incompatibility with conventional phacoemulsification protocols. Such patients face a markedly elevated risk of both anterior and posterior segment perioperative complications, posing a persistent clinical challenge in cataract surgery. Focusing on the unique ocular anatomical characteristics associated with high myopia, this review systematically summarizes the distinct traumatic effects and pathological impacts of phacoemulsification on the anterior and posterior ocular segments of affected patients. Moving beyond generalized discussions of routine cataract management, it consolidates clinical evidence specific to this special-population patients, aiming to provide refined references for perioperative risk prevention and control in cataract patients complicated with high myopia.

Objective:To evaluate the role of the TANK-binding kinase 1 (TBK1)/receptor-interacting protein kinase 1 (RIPK1) signaling pathway in postoperative cognitive dysfunction (POCD) in aged mice.Methods:Fifty SPF healthy male C57BL/6 mice, aged 18 months, weighing 20-25 g, were divided into 5 groups ( n=10 each) using a table of random numbers: control group (group C), POCD group, dimethyl sulfoxide group, GSK group and GSK+ Nec-1 group. A mouse model of POCD was established by the closed reduction internal fixation of the left tibial fracture in anesthetized animals. Dimethyl sulfoxide, TBK1 inhibitor GSK8612 and RIPK1 inhibitor Nec-1 (0.5 μl/side) were stereotactically injected into the hippocampal CA1 region at 30 min before operation. Cognitive function was assessed using the contextual fear conditioning test before operation and at 3 days after operation. The mice were then anesthetized and sacrificed, and the hippocampal tissues were obtained for determination of the expression of TBK1, RIPK1, interleukin-lbeta (IL-1β), tumor necrosis factor-alpha (TNF-α), activator protein 1 (AP-1) and Nestin (by Western blot), the expression of Bcl-2, Bax and caspase-3 mRNA (by fluorescent quantitative real-time polymerase chain reaction) and for examination of TBK1/RIPK1 molecular interactions and neural stem cell proliferation in the hippocampal dentate gyrus (DG) region (by immunofluorescent staining). Results:Compared with C group, the percentage of freezing time was significantly decreased at 3 days after operation, the expression of Bax mRNA, caspase-3 mRNA, RIPK1, IL-1β, TNF-α and AP-1 was up-regulated, the expression of TBK1, Bcl-2 mRNA and Nestin was down-regulated, and the proliferation of neural stem cells in the hippocampal DG region was decreased in POCD group ( P<0.05 or 0.01). Compared with POCD group, the percentage of freezing time was significantly decreased at 3 days after operation, the expression of Bax mRNA, caspase-3 mRNA, IL-1β, TNF-α and AP-1 was up-regulated, the expression of TBK1, Bcl-2 mRNA and Nestin was down-regulated, and the proliferation of neural stem cells in the hippocampal DG region was decreased in GSK group ( P<0.05 or 0.01). Compared with GSK group, the percentage of freezing time was significantly increased at 3 days after operation, the expression of Bax mRNA, caspase-3 mRNA, IL-1β, TNF-α and AP-1 was down-regulated, the expression of TBK1, Bcl-2 mRNA and Nestin was up-regulated, and the proliferation of neural stem cells in the hippocampal DG region was increased in GSK+ Nec-1 group ( P<0.05 or 0.01). Conclusions:The TBK1/RIPK1 signaling pathway is involved in the pathogenesis of POCD in aged mice.

AIM: To compare the changes in corneal epithelial thickness(CET)after small incision lenticule extraction(SMILE)and femtosecond laser-assisted in situ keratomileusis(FS-LASIK).METHODS: A total of 187 patients(187 eyes)who underwent either SMILE or FS-LASIK at Urumqi Aier Eye Hospital between December 2022 and November 2023 were collected. The patients were divided into SMILE group and FS-LASIK group according to surgical methods. The CET of the patients was measured by optical coherence tomography(OCT)system before surgery and at 1 wk, 1, 3, and 6 mo postoperatively.RESULTS: Changes in corneal epithelial thickness(△CET)in the central, paracentral, and mid-peripheral regions were compared at 6 mo postoperatively. The SMILE group was characterized by the most significant thickening in the central area and the least thickening in the mid-peripheral area; while the FS-LASIK group was characterized by the most significant thickening in the paracentral area and the least thickening in the mid-peripheral region. At 1 wk, 1, 3, and 6 mo postoperatively, within the 0-7 mm corneal area, the △CET for both the SMILE and FS-LASIK groups was correlated with the preoperative spherical equivalent.CONCLUSION: Within 6 mo postoperatively, both SMILE and FS-LASIK showed a similar trend in epithelial thickening but with distinct characteristics. The change in corneal epithelial thickness for both procedures was positively correlated with the preoperative diopter.

Endovascular aneurysm repair(EVAR)is the most common treatment for abdominal aortic aneurysm.However,when the common iliac artery has expansion or aneurysm,there may be internal leakage at the distal end of the stent.In this case,the ideal endovascular repair should ensure the pelvic blood supply on the premise of complete exclu-sion of the aneurysm.It is feasible and safe to use iliac branch devices(IBD)to preserve unilateral or bilateral internal iliac arteries,and its technology and clinical results are equivalent to standard EVAR.But IBD has certain anatomical a-daptability.In this paper,the current status of preservation of internal iliac artery with IBD is systematically reviewed.

Background and Aims:Abdominal aortic aneurysm(AAA)is a common arterial dilation disease in vascular surgery,with aneurysm rupture being its most serious complication,often leading to fatal hemorrhage and posing a severe threat to patients'lives.Endovascular aneurysm repair(EVAR),due to its minimally invasive nature,safety,and rapid recovery,has become the preferred treatment for AAA.However,endoleak,a complication unique to EVAR,remains a major clinical challenge.Persistent endoleak can lead to sustained high pressure within the aneurysm sac,increasing the risk of continued expansion and rupture.It is one of the main causes of the high reintervention rate following EVAR.In particular,the treatment strategy for type Ⅱ endoleaks remains controversial.This study was conducted to evaluate the clinical value of selective sac embolization via the iliac approach combined with standard EVAR in managing intraoperative immediate endoleaks.Methods:The clinical data of AAA patients with a risk of endoleak who underwent standard EVAR at the First Hospital of China Medical University between March 2023 and September 2024 were retrospectively collected.Patients were divided into an intervention group(n=42)and a non-intervention group(n=32)based on whether selective sac embolization via the iliac approach was performed during operation.General clinical data,preoperative anatomical characteristics of the AAA,surgical details,and postoperative follow-up results were compared between the two groups.Results:There were no statistically significant differences between the two groups in terms of age,sex,anatomical features,rupture rate,or off-label use(all P>0.05).The technical success rate during surgery was 100%in both groups.One patient in the intervention group experienced transient sigmoid colon ischemia after operation,which resolved with conservative treatment.The mean follow-up period was(6.49±4.68)months.The proportions of aneurysm sac shrinkage,stability,and enlargement in the intervention group were 40.5%,57.1%,and 2.4%,respectively,compared to 59.4%,40.6%,and 0.0%in the non-intervention group,with no statistically significant differences(all P>0.05).The incidence of endoleak during follow-up was also comparable between the two groups(P>0.05).Conclusion:For intraoperative endoleaks during standard EVAR,selective sac embolization via the iliac approach is a technically simple and safe method that provides short-term outcomes comparable to those in patients without intraoperative endoleaks.Its long-term efficacy warrants further investigation through extended follow-up.

Objective To investigate the effect of orthosis design parameters on correction of scoliosis and orthosis-trunk interface pressure.Methods A finite element model of scoliosis was constructed to simulate the assembly effect of the orthosis.The orthosis was divided into four loading areas(left rib,right rib,anterior-left and posterior-right area)to simulate six modification conditions.In Models 1,2 and 3,a fixed modification of 20 mm was applied on the anterior left and posterior right areas,while the displacement loads of 20,25 and 30 mm were applied on both the left rib and right rib areas.In Models 4,5 and 6,a fixed modification of 25 mm was applied on left rib and right rib areas,with the displacement loads of 15,20 and 25 mm applied on both anterior left and posterior right areas.The Cobb angle,apical vertebral rotation(AVR)and interface pressure were calculated.Results The correction of Cobb angle in Models 1,2 and 3 was 8.94°,15.62° and 17.91°,respectively,with AVR correction of 7.53°,6.69° and 5.87°,respectively.In Models 4,5 and 6,the correction of Cobb angle was 14.55°,15.62° and 16.09°,with AVR correction of 5.25°,6.69° and 8.63°,respectively.In Model 6,the correction rate of Cobb angle and AVR was 45.48%and 41.22%,respectively,with a maximum pressure of 26.51 kPa on orthosis-trunk interface,achieving the most significant outcome.Conclusions The modification of orthosis has a significant effect on the correction of Cobb and AVR angles.The loading on the left rib and right rib areas mainly affect the Cobb angle,while the loading on the anterior left and posterior right areas mainly affect the spinal axial-rotation.A modification of 25 mm on all loading areas achieves the optimal spinal correction.This study provides the quantitative data for orthosis design.
