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 evaluate the technical feasibility and perioperative safety of pyeloplasty assis-ted by the CarinaTM modular laparoscopic surgical robotic system in patients with ureteropelvic junction obstruction(UPJO).Methods:From November to December 2024,five consecutive patients diagnosed with UPJO underwent robot-assisted pyeloplasty using the CarinaTM modular laparoscopic surgical system at Peking University First Hospital.Data on patient demographics,intraoperative parameters(including docking time,console time,and estimated blood loss),perioperative outcomes,follow-up results,and surgeons' subjective evaluations of system performance were prospectively collected.Descriptive statistics were used;continuous variables were presented as median(range),and categorical variables as frequen-cy and percentage.Results:The cohort included four females and one male.All the patients successfully completed the robotic procedure without conversion to open or conventional laparoscopic surgery.The me-dian age was 32 years(24-37 years),and the median body mass index was 21.6 kg/m2(15.8-27.3 kg/m2).The median docking time was 8 min(3-12 min),and the median console time was 91 min(71-125 min).Intraoperative blood loss was uniformly 20 mL.The median postoperative drainage du-ration was 3 d(0-4 d),and the median length of hospital stay was 4 d(4-9 d).No Clavien-Dindo grade Ⅲ or higher complications occurred.All the patients had their double-J stents removed at 2 months postoperatively,and pain in the ipsilateral flank,reported preoperatively by all the five patients,was al-leviated.The subjective surgical success rate was 100％.Surgeons reported stable system performance throughout all the procedures,with no instances of mechanical arm interference or visual drift affecting surgical fluency.Conclusion:Preliminary findings indicate that pyeloplasty using the domestically deve-loped CarinaTM modular laparoscopic robotic system is technically feasible and perioperatively safe for the treatment of UPJO.

Objective:To construct a risk prediction model for early post-injury respiratory failure in patients with traumatic cervical spinal cord injury (TCSCI) and validate its efficacy.Methods:A retrospective cohort study was conducted to analyze the clinical data of 393 TCSCI patients admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University from January 2020 to October 2024, including 294 males and 99 females, aged 18-82 years [59(45, 72)years]. Among them, 76 patients had respiratory failure (19.3%). The patients were randomly divided into the training set ( n=275) and validation set ( n=118) at a ratio of 7∶3. According to the presence of respiratory failure within one week after admission, 275 patients in the training set were divided into respiratory failure group ( n=53) and non-respiratory failure group ( n=222). The demographic data, injury characteristics, laboratory test results, and imaging findings of the patients were collected. Risk factors were determined through univariate analysis and multivariate Logistic regression analysis and a nomogram prediction model was constructed. The area under the receiver operating characteristic (ROC) curve (AUC) and Hosmer-Lemeshow test were used to evaluate the discrimination and calibration of the model. Decision curve analysis (DCA) was plotted to evaluate the clinical effectiveness of the prediction model. Results:The results of the univariate analysis showed that there were significant differences in history of respiratory diseases, causes of injury, Glasgow coma scale (GCS), American Spinal Injury Association (ASIA) classification, ASIA-motor score (AMS), injury severity score (ISS), clinical pulmonary infection score (CPIS), hypoproteinemia and cervical vertebra fracture and dislocation between the respiratory failure group and non-respiratory failure group in the training set ( P<0.05). The results of multivariate Logistic regression analysis indicated that GCS, ASIA classification, CPIS, and hypoproteinemia were independent risk factors for early post-injury respiratory failure in TCSCI patients ( P<0.05). Based on the above four variables, a Logistic regression equation was constructed: Logit( P)=2.361-0.675×ASIA classification+0.419×CPIS-0.358×GCS+0.854×hypoproteinemia. In the prediction model established based on this equation, the AUC was 0.96 (95% CI 0.94, 0.99) in the training set and 0.89 (95% CI 0.82, 0.96) in the validation set. In the calibration curves of the training set and validation set, the prediction curve and reference curve were approximately overlapping, with the average absolute errors of 0.04 and 0.03. DCA results demonstrated that both the training and validation sets exhibited positive net benefits when threshold probabilities fell within ranges of 0%-78% and 0%-87%, respectively. Conclusion:The risk prediction model for early post-injury respiratory failure in TCSCI patients based on GCS, ASIA classification, CPIS and hypoproteinemia has good predictive efficacy and clinical practicability.

Objective:To investigate the mechanism of Fusobacterium nucleatum ( Fn) in regulating the formation of neutrophil extracellular trap (NET) to aggravate colitis. Methods:With a completely randomized design, 15 C57BL/6 mice were randomly divided into negative control group, dextran sulfate sodium (DSS) A group (DSS-induced colitis), and DSS+ Fn A group (DSS-induced colitis with Fn infection); another 15 C57BL/6 mice were randomly divided into DSS B group, DSS+ Fn B group, and GSK484 group (DSS-induced colitis with Fn infection and followed by intraperitoneal injection of peptidylarginine deiminase 4 (PAD4)inhibitor GSK484), with 5 mice in each group. The Fn-infected neutrophils (HL-60 cell) model and PAD4-inhibited cell model were established and divided into neutrophil-like control cell (induced with 1.25% dimethylsulfoxide), Fn+ neutrophil-like cell (neutrophil-like cells co-cultured with Fn), and GSK484 cell ( Fn+ neutrophil-like cell co-cultured with GSK484) with a completely randomized design. The neutrophil-like control and Fn+ neutrophil-like cells were divided into 2 batches to conduct experiments before and after PAD4 inhibition separately.The expression of zonula occludens-1 (ZO-1), neutrophil elastase (NE), reactive oxygen species, PAD4, and citrullinated histone H3(cit-H3) were analyzed by immunohistochemistry staining, Western blotting, and flow cytometry assay. Two-tailed t test was used for statistical analysis. Results:The results of immunohistochemical staining showed that compared with those of the DSS A group, the expression levels of NE, PAD4 and cit-H3 of the DSS+ Fn A group were upregulated, and the expression level of ZO-1 was downregulated; compared with those of the DSS+ Fn B group, the expression level of ZO-1 of the GSK484 group was upregulated, and the expression levels of cit-H3 and PAD4 were downregulated. The results of Western blotting demonstrated that, before the PAD4 inhibition, the expression levels of NE, PAD4 and cit-H3 of the Fn+ neutrophil-like cell were all higher than those of the neutrophil-like control cell (1.52±0.11 vs. 1.00±0.19, 1.21±0.06 vs. 1.00±0.07, 1.59±0.16 vs. 1.00±0.16), and the differences were statistically significant ( t=-4.13, -3.86, and -4.47; P=0.014, 0.014, and 0.018); after the PAD4 inhibition, the expression levels of PAD4, cit-H3, and NE of the GSK484 cell were all lower than those of the Fn+ neutrophil-like cell (0.95±0.09 vs. 1.27±0.04, 1.15±0.34 vs. 2.29±0.50, 1.22±0.14 vs. 1.68±0.12), and the differences were statistically significant ( t=5.61, 3.24, and 4.49; P=0.005, 0.032, and 0.011). The results of flow cytometry assay indicated that the positive rate of reactive oxygen species of the DSS+ Fn A group was higher than that of the DSS A group ((21.15±2.93)% vs. (11.14±1.42)%), and the positive rate of reactive oxygen species of the Fn+ neutrophil-like cell was also higher than that of the neutrophil-like control cell before the PAD4 inhibition ((51.69±6.94)% vs.(31.95±3.31)%), and the differences were statistically significant( t=5.33 and 4.45, P=0.006 and 0.011). Conclusion:Fn can promote neutrophil to release NET by upregulating reactive oxygen/PAD4/cit-H3 signaling pathway, which disrupt the intestinal barrier and aggravate colitis.

Background and purpose:Human papilloma virus(HPV)infection status is crucial for diagnosing cervical precancerous lesions and classifying cervical cancer.High-risk(HR)HPV is often linked to P16 protein overexpression,so P16 detection via immunohistochemistry(IHC)is commonly used to assess HPV infection.However,the differences between HPV status and P16 expression remains unclear.An in-depth study of the correlation between HPV and P16 is essential for clinical guidance.Methods:We retrospectively collected clinical and pathological data of cervical lesions from 618 patients diagnosed at the Department of Pathology,Fudan University Shanghai Cancer Center from January 2020 to December 2023(Ethical number:050432-4-2307E).Polymerase chain reaction(PCR)reverse dot hybridization was used to detect HPV including HR and low-risk(LR)subtypes,and immunohistochemistry was used to detect P16 for comparative analysis.Based on different clinical and pathological diagnoses,the sensitivity and specificity of P16 expression in evaluating HPV infection were evaluated.Among the 618 cases of cervical lesions,there were 92 cases of cervical squamous cell carcinoma,257 cases of cervical adenocarcinoma,79 cases of high-grade squamous intraepithelial lesions(HSIL),105 cases of low-grade squamous intraepithelial lesions(LSIL),and 85 cases of chronic cervical inflammation.Results:According to clinical diagnosis,the HR-HPV positive rate in cervical squamous cell carcinoma was 88.0%(81/92),the P16 positive rate was 91.3%(84/92),and the overall consistency rate between P16 and HPV detection was 90.2%(88/92);for HR-HPV infection,the sensitivity and specificity of P16 were 96.3%and 45.5%.The positive rate of HR-HPV in adenocarcinoma was 54.5%(140/257),the positive rate of P16 was 58.8%(151/257),and the overall consistency rate between P16 and HPV detection was 82.5%(212/257);for HR-HPV infection,the sensitivity and specificity of P16 were 87.9%and 76.1%.In HSIL,the HR-HPV positive rate was 75.9%(60/79),the positive rate of P16 was 70.9%(56/79),and the overall consistency rate between P16 and HR-HPV detection was 82.2%(65/79);for HR-HPV infection,the sensitivity and specificity of P16 were 85.0%and 73.7%.In LSIL,the HR-HPV positive rate was 73.3%(77/105),the positive rate of P16 was 8.5%(9/105),and the overall consistency rate between P16 and HR-HPV detection was 33.3%(35/105);for HR-HPV infection,the sensitivity and specificity of P16 were 10.4%and 96.4%.In chronic cervical inflammation,the HR-HPV positive rate was 20%(17/85),the positive rate of P16 was 0.0%(0/85);for HR-HPV infection,the sensitivity and specificity of P16 were 0.0%and 100.0%.There was a significant positive correlation between P16 positivity and HPV16/18 in cervical squamous cell carcinoma,adenocarcinoma,and HSIL(P=0.000),while there was no significant correlation in LSIL and chronic cervical inflammation(P＞0.05).Conclusion:In cervical squamous cell carcinoma and adenocarcinoma,the consistency of P16 expression and HPV DNA positivity are high,especially in HPV16/18 subtype.There is a good concordance between HR-HPV positivity and P16 protein overexpression.The positive expression of P16 in HSIL may initially reflect HPV infection status.However,in LSIL and chronic cervicitis,P16 expression may not accurately correlate with HPV infection.The inconsistency between P16 and HPV DNA testing could be influenced by multiple factors,including HPV subtypes,histopathological categories,specimen quality,and technical limitations.In clinical practice,it is recommended to conduct comprehensive analysis or employ multiple diagnostic methods to confirm HPV infection status for precise evaluation.

BACKGROUND:Bone marrow mesenchymal stem cells are one of the sources of adipocytes and express all renin-angiotensin system components,but the effect of angiotensin Ⅱ on bone marrow mesenchymal stem cell differentiation into brown adipose tissue is not clear.OBJECTIVE:To observe the effect of angiotensin Ⅱ on bone marrow mesenchymal stem cell differentiation into brown adipose tissue and investigate the role of angiotensin 1a receptor knockout in effect of angiotensin Ⅱ on bone marrow mesenchymal stem cell differentiation into brown adipocytes and its potential mechanisms.METHODS:After isolation and culture of bone marrow mesenchymal stem cells in wild-type and angiotensin 1a receptor knockout SD rats,the cells were cultured to the third generation and randomly divided into four groups:wild type group,knockout group,wild type+angiotensin Ⅱ group,and knockout+angiotensin Ⅱ group.The differentiation was induced in the brown fat induced differentiation medium for 14 days.Angiotensin Ⅱ(100 nmol/L)was added for intervention when the differentiation medium was changed each time in the latter two groups.Western blot assay,qRT-PCR,immunofluorescence,and other methods were used to detect the expression of induced differentiation,lipolysis,β oxidation,and mitochondrial biogenesis in brown fat.RESULTS AND CONCLUSION:Angiotensin Ⅱ could inhibit the browning of rat bone marrow mesenchymal stem cells.Knockout of angiotensin 1a receptor could improve the inhibitory effect of angiotensin Ⅱ on brown lipid formation of rat bone marrow mesenchymal stem cells by promoting lipolysis,enhancing fatty acid β oxidation,promoting mitochondrial biogenesis,and enhancing mitochondrial function.These findings provide new research directions and potential therapeutic targets for obesity treatment,revealing the important role of renin angiotensin systems in fat metabolism and its potential as a therapeutic target.

Purpose To analyze the impact of early renal complication on brain function in diabetes using the amplitude of low frequency fluctuations(ALFF)and functional connectivity(FC).Materials and Methods A total of 39 early diabetic kidney disease patients and 49 diabetic patients without kidney disease were included at the First Affiliated Hospital of Army Medical University from September 2023 to June 2024.Cognitive assessments were conducted using the Montreal cognitive assessment(MoCA)and mini-mental state examination(MMSE).All subjects underwent resting-state functional magnetic resonance imaging.Differences in brain function between the two groups were analyzed by ALFF and FC.In the early diabetic kidney disease group,the correlation and stepwise multiple linear regression analysis were performed between imaging difference indicators and clinical variables.Results In the early diabetic kidney disease patients,there was a decrease in ALFF values in the left calcarine(P<0.05,corrected for FWE),but an increase in FC with the left putamen(P<0.05,corrected for FWE).The ALFF values showed a negative correlation with urinary albumin-to-creatinine ratio and total cholesterol(r=-0.595,-0.351,both P<0.05)and a positive correlation with MoCA and MMSE scores(r=0.596,0.591,both P<0.001).The FC values were positively correlated with urinary albumin-to-creatinine ratio(r=0.552,P<0.001),while negatively correlated with MoCA and MMSE scores(r=-0.497,P=0.011;r=-0.529,P<0.001).Conclusion Early renal complications can affect changes in brain function and cognitive abilities in diabetic patients;alterations in the ALFF of the left calcarine and its FC with left putamen may serve as imaging biomarkers for monitoring cognitive impairment and brain injury in early diabetic kidney disease.
