With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

Objective To explore the epidemiological characteristics of gouty arthritis in Northwest China from 2023 to 2025, and to formulate preventive intervention measures. Methods By retrospectively analyzing the case data of medical institutions in Northwest China from January 2023 to June 2025 (a total of 8 139 cases), the incidence trend and population distribution characteristics of gouty arthritis in this area were analyzed. Multivariate logistic regression analysis was performed to identify risk factors. Results From 2023 to 2025, the prevalence rate of gouty arthritis in adult residents in Northwest China was 3.74% (304/8 139). Among the sites affected by gouty arthritis, the metatarsophalangeal joint accounted for the highest proportion (P<0.05). From the perspective of age distribution, the prevalence rate was the highest in 40-59 years old group (5.90%), followed by 66-80 years old group (4.21%) and >80 years old group (2.75%). The incidence rate in 40-65 years old group was higher than that in the other age groups (P<0.05). High blood uric acid and creatinine, alcohol drinking, obesity, high purine diet, concurrent chronic kidney disease and metabolic syndrome were risk factors affecting gouty arthritis in Northwest China (P<0.05). Conclusion High blood uric acid level, high creatinine level, alcohol drinking, obesity, high purine diet, concurrent chronic kidney disease and metabolic syndrome are risk factors influencing gouty arthritis in Northwest China. Based on the above factors, this study proposes comprehensive prevention strategies from the individual, community and public health levels to provide a scientific basis for reducing the incidence rate of gouty arthritis.

OBJECTIVE: To analyze the efficacy and safety of decitabine-based myeloablative preconditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with acute myeloid leukemia (AML). METHODS: The clinical characteristics and efficacy of 115 AML patients who underwent allo-HSCT at the First Medical Center of Chinese PLA General Hospital from August 2018 to August 2022 were retrospectively analyzed, including 37 patients treated with decitabine conditioning regimen (decitabine group) and 78 patients without decitabine conditioning regimen (non-decitabine group). The cumulative incidence of relapse (CIR), overall survival (OS), leukemia-free survival (LFS), non-relapse mortality (NRM) and graft versus host disease (GVHD) were analyzed. RESULTS: For the patients in first complete remission (CR1) state before allo-HSCT, the 1-year relapse rates of decitabine group(22 cases) and non-decitabine group(69 cases) were 9.1% and 29.6%, respectively, the difference was statistically significant(P =0.042). The 1-year cumulative incidence of acute graft-versus-host disease (aGVHD) in decitabine group and non-decitabine group was 62.2% and 70.5%, respectively, and the 1-year cumulative incidence of chronic inhibitor-versus-host disease (cGVHD) was 18.9% and 14.1%, respectively, there were no significant differences in the incidence of aGVHD and cGVHD between the two groups (P >0.05). Of the 115 patients, there were no significantly differences in the 1-year CIR(21.7% vs 28.8%, P =0.866), NRM(10.9% vs 3.9%, P =0.203), OS(75.2% vs 83.8%, P =0.131) and LFS(74.6% vs 69.1%, P =0.912) between the decitabine group(37 cases) and the non-decitabine group(78 cases). CONCLUSION Decitabine-based conditioning regimen could reduce the relapse rate of AML CR1 patients with good safety.

BACKGROUND: The association between uric acid-albumin ratio (UAR) with different diseases has been evaluated before. However, the association between UAR with spontaneous reperfusion (SR) in patients with ST-segment elevation myocardial infarction (STEMI) has not been explored. METHODS: STEMI patients admitted to our department and underwent primary coronary angiography between 1^st November 2018 and 31^st December 2020 were retrospectively enrolled. The patients were divided into the SR group and the non-SR group according to the index coronary angiography results. The association between UAR and SR was evaluated by uni-variable and multi-variable logistic analysis. Receiver operating characteristic curve analysis was used to determine the optimum cut-off level of UAR in predicting SR. RESULTS: Three hundred and fifty-seven patients were finally enrolled in our study, 55 patients were divided into the SR group and 302 patients were divided into the non-SR group. In uni-variable analysis, patients with SR were older (P = 0.032), with higher red blood cell distribution width (P < 0.001) and red blood cell distribution width-to-platelet ratio (P < 0.001), higher level of C-reactive protein (P = 0.046), higher level of uric acid (P < 0.001) compared with patients without SR. Patients with SR had a lower level of platelets (P = 0.008), lower level of on-admission B-type natriuretic peptide (P < 0.001). As for the level of UAR, STEMI patients with SR had significantly higher levels of UAR compared with STEMI patients without SR [11.1 (8.9-13.4) vs. 8.3 (6.6-10.0), P < 0.001]. Further multi-variable logistic analysis reveals that UAR was the independent risk factor of SR in different models after adjusting different variables. Receiver operating characteristic analysis showed that UAR had good predictive value in SR (AUC = 0.75, 95% CI: 0.702-0.794, P < 0.01). CONCLUSIONS Our study shows that UAR is an independent risk factor for predicting SR in STEMI patients.

Objective:To compare the curative effects of modified urethral plate reconstruction rolled duct urethroplasty (modified Koyanagi operation), Duckett operation and tubularized incised plate urethroplasty (TIP operation) in the treatment of hypospadias in children.Methods:The clinical data of 100 cases of children with hypospadias admitted to the Third People′s Hospital of Xinjiang Uygur Autonomous Region from January 2018 to June 2022 were analyzed retrospectively. According to different surgical schemes, they were divided into 3 groups, 30 cases performed modified Koyanagi operation were set as group A, 35 cases performed Duckett operation were set as group B, and 35 cases performed TIP operation were set as group C. The recovery time of urination function, hospital stay, overall treatment effect and postoperative complications were compared among the three groups.Results:There were no significant differences in the recovery time of micturition function, hospitalization time, intraoperative blood loss and operation time among the three groups ( P>0.05). The incidence of postoperative complications among the group A, B and C were 20.00%(6/30), 28.57%(10/35), 2.98%(1/35), and the incidence of postoperative complications in the group C was lower than that in the group A and group B ( χ2 = 4.94 and 8.74, P<0.05). Conclusions:In the treatment of hypospadias in children by Modified Koyanagi operation, Duckett operation and TIP operation have no significant difference in curative effect, but TIP operation has fewer postoperative complications.

BACKGROUND:Studies have shown that vascular factors have an important impact on the occurrence of diabetic foot.OBJECTIVE:To investigate the important role of angiopoietin-like protein 4 in the formation of diabetic foot.METHODS:(1)Bioinformatics analysis was performed on the gene expression profile data of diabetic foot patients to find the key genes.The skin samples of diabetic foot patients and healthy people were collected for hematoxylin-eosin staining,immunohistochemical staining,and qRT-PCR experiments to detect the expression of angiopoietin-like protein 4.(2)The immortalized human skin fibroblast cell line and primary human umbilical vein endothelial cells were cultured.The two kinds of cells were divided into control group and exogenous angiopoietin-like protein 4 supplemented group.The migration ability and proliferation ability of fibroblasts were detected by scratch assay and CCK-8 assay.The proliferation ability of endothelial cells was detected by Ki67 assay.RESULTS AND CONCLUSION:(1)Bioinformatics analysis results showed that the down-regulation of angiopoietin-like protein 4 gene might be the key gene leading to the formation of diabetic foot.(2)Hematoxylin-eosin staining exhibited that compared with normal skin,angiopoietin-like protein 4 was weakly expressed in diabetic foot skin,and the mRNA level was decreased(P＜0.01).(3)Scratch assay results demonstrated that compared with the control group,fibroblast migration ability was significantly enhanced in the angiopoietin-like protein 4 group.CCK-8 assay showed that the absorbance value of fibroblasts in the angiopoietin-like protein 4 group was higher than that of the control group at 24 and 48 hours(P＜0.01,P＜0.001).It is suggested that angiopoietin-like protein 4 can enhance the migration and proliferation of fibroblasts.(4)Ki67 assay results demonstrated that the number of Ki67 positive cells in the angiopoietin-like protein 4 group was significantly more than that in the control group.CCK-8 assay results showed that the absorbance value of endothelial cells in the angiopoietin-like protein 4 group was higher than that of the control group at 24 and 48 hours(P＜0.05,P＜0.001).(5)All findings suggest that angiopoietin-like protein 4 can enhance the proliferation of endothelial cells treated with high glucose.

Oncolytic viruses can selectively infect and kill tumor cells.Since China's first oncolytic virus product re-combinant human 5 adenovirus H101 was approved for market in 2005,four oncolytic virus products have entered the market globally.More than 200 clinical trials of oncolytic virus therapies have been conducted worldwide.However,the number of globally approved indications for oncolytic virus products remains limited,and the potential patient populations and therapeutic mechanisms require further clinical investigation.To further optimize the clinical trial design of oncolytic virus products in China,this consensus was developed based on the"Guiding principles for clinical trial design of oncolytic virus drugs(trial version)"issued by the National Medical Products Administration(NMPA).Based on the medicine method,from the perspective of the mechanism of action of oncolytic virus,development indication,clinical application mode,clinical trial biology and pharmacodynamic detection,etc.,multidisciplinary expert meeting discussion and ques-tionnaire survey were carried out based on the considerations and related contents of the current clinical trial design of oncolytic virus.After three rounds of opinion collection,combing and summarizing,the"Chinese expert consensus on the key points of oncolytic virus clinical trial design(2024 edition)"was formed,aiming to provide references for sponsors and re-searchers of clinical trials of oncolytic virus products in China,help related products quickly go to market,and achieve new breakthroughs in tumor treatment.

AIM:This study aims to investigate the effects of baicalin on the hypoxia-inducible factor-1α(HIF-1α)/solute carrier family 7 member 11(SLC7A11)/glutathione peroxidase 4(GPX4)axis and the ferroptosis induced by oxidized low-density lipoprotein(ox-LDL)in RAW264.7 macrophage-derived foam cells.METHODS:RAW264.7 cells were categorized into five groups:control,ox-LDL,baicalin+ox-LDL,ferrostatin-1(Fer-1;ferroptosis inhibitor)+ox-LDL,and baicalin+Fer-1+ox-LDL.To induce foam cell formation,RAW264.7 macrophages were exposed to 100 μg/mL ox-LDL for 24 h.Oil red O staining was employed to visualize lipid droplet formation in each group.The ultrastructure of the mitochondria was examined using transmission electron microscopy.Fluorescence microscopy was utilized to assess the fluorescence intensity of intracellular reactive oxygen species(ROS),lipid peroxides,and Fe2+.A colorimetric assay facilitated the measurement of malondialdehyde(MDA)and glutathione(GSH)levels.Additionally,Western blot analy-sis was conducted to quantify protein levels of HIF-1α,SLC7A11,and GPX4.RESULTS:The model group exhibited foam cell formation,abundant lipid droplets,significant swelling of mitochondrial structures,and observable shortening or disappearance of cristae.There was a marked increase in intracellular fluorescence intensity of ROS,lipid peroxides,and Fe2+,alongside elevated MDA levels and decreased GSH levels.HIF-1α protein expression was significantly increased,while SLC7A11 and GPX4 protein expressions were notably decreased(P<0.05).In comparison to the model group,both the baicalin+ox-LDL and Fer-1+ox-LDL groups demonstrated a significant reduction in lipid droplets,improved mitochon-drial structures,decreased fluorescence intensity of ROS,lipid peroxides,and Fe2+,as well as lower MDA levels and higher GSH levels.Additionally,HIF-1α expression significantly decreased,while SLC7A11 and GPX4 expressions sig-nificantly increased(P<0.05).Furthermore,the baicalin+Fer-1+ox-LDL group showed a more pronounced reduction in lipid droplets,near-normal mitochondrial structures,lower fluorescence intensity of ROS,lipid peroxides,and Fe2+,de-creased MDA levels,and increased GSH levels compared to the baicalin+ox-LDL group;HIF-1α,SLC7A11,and GPX4 protein expressions were also significantly reduced(P<0.05).CONCLUSION:Baicalin modulates the HIF-1α/SLC7A11/GPX4 axis,thereby inhibiting ox-LDL-induced ferroptosis in macrophage-derived foam cells.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.
