Patients with lung cancer experience a heavy symptom burden during the perioperative period, which seriously affects their recovery and quality of life. Traditional symptom management models rely mainly on scheduled ward rounds during hospitalization and outpatient follow-up after discharge. However, they have limitations such as delayed symptom recognition, lack of post-discharge monitoring, and non-quantitative symptom assessment, which often lead to delayed interventions and low patient satisfaction. In recent years, the symptom management model based on electronic patient-reported outcomes (ePRO) has been increasingly valued in clinical practice. Existing high-level evidence from both domestic and international studies indicates that, through proactive monitoring, real-time alerts, and remote interventions, this model enables dynamic and continuous symptom management and helps improve patient recovery and healthcare experience. As a supplement to routine medical care, the ePRO-based symptom management model aims to enhance the quality of care rather than replace existing medical processes. To promote the standardized application of this model in perioperative lung cancer care, this consensus integrates domestic and international evidence. After multiple rounds of voting by more than 50 experts, it formulates 12 consensus statements covering the three core components, symptom monitoring, alerting, and intervention, to provide scientific and practical recommendations for clinical practice.

With the widespread adoption of low-dose CT screening and the extensive application of high-resolution CT, the detection rate of sub-centimeter lung nodules has significantly increased. How to scientifically manage these nodules while avoiding overtreatment and diagnostic delays has become an important clinical issue. Among them, lung nodules with a consolidation tumor ratio less than 0.25, dominated by ground-glass shadows, are particularly worthy of attention. The therapeutic challenge for this group is how to achieve precise and complete resection of nodules during surgery while maximizing the preservation of the patient's lung function. The "watershed topography map" is a new technology based on big data and artificial intelligence algorithms. This method uses Dicom data from conventional dose CT scans, combined with microscopic (22-24 levels) capillary network anatomical watershed features, to generate high-precision simulated natural segmentation planes of lung sub-segments through specific textures and forms. This technology forms fluorescent watershed boundaries on the lung surface, which highly fit the actual lung anatomical structure. By analyzing the adjacent relationship between the nodule and the watershed boundary, real-time, visually accurate positioning of the nodule can be achieved. This innovative technology provides a new solution for the intraoperative positioning and resection of lung nodules. This consensus was led by four major domestic societies, jointly with expert teams in related fields, oriented to clinical practical needs, referring to domestic and foreign guidelines and consensus, and finally formed after multiple rounds of consultation, discussion, and voting. The main content covers the theoretical basis of the "watershed topography map" technology, indications, operation procedures, surgical planning details, and postoperative evaluation standards, aiming to provide scientific guidance and exploration directions for clinical peers who are currently or plan to carry out lung nodule resection using the fluorescent microscope watershed analysis method.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To explore the effects of early electroacupuncture(EA)intervention on the high mobility group box 1(HMGB1)/Toll-like receptor 4(TLR4)signaling pathway-related protein expression and oligodendrocytes in mice with amyotrophic lateral sclerosis(ALS),and uncover the potential molecular mechanisms underlying the improvement of motor function in ALS mice by early EA intervention.Methods:ALS mice carrying the SOD1G93A gene were randomly divided into a model group and an EA group,with 10 mice in each group;10 littermate mice with a negative SOD1G93A genotype served as the control group.In the EA group,Baihui(GV20),Tianzhu(BL10),and Tianshu(ST25)were selected with needles retained for 10 min,5 consecutive days per week,with 2 days of rest.One week constituted a course of treatment,and a total of 3 consecutive courses were performed.The other groups were grasped and fixed similarly,but without intervention.Motor function was assessed using the open field test(OFT)and Morris water maze(MWM).Subsequently,hematoxylin-eosin staining was used to observe neuron morphology in the M1 region of the cerebral cortex.Immunofluorescence was performed to detect the positive cell rate of TAR DNA-binding protein 43(TDP-43),and double immunofluorescence staining was used to observe the positive cell rate and cell states of ionized calcium-binding adaptor molecule 1(Iba-1)and myelin basic protein(MBP)in the M1 region of the cerebral cortex.Western blotting was used to detect the relative expression levels of TDP-43,tumor necrosis factor(TNF)-α,HMGB1,and TLR4 proteins.Results:Compared to the control group,the model group exhibited a reduced total movement distance in the OFT,and an increased escape latency,as well as fewer platform crossings in the MWM,with statistically significant differences(P<0.01).In the model group,the number of degenerated and necrotic neurons in the M1 region of the ALS mouse cerebral cortex increased,with significant nuclear shrinkage and cytoplasmic vacuolization;the percentage of TDP-43 immunofluorescence positive cells in the M1 region of the cerebral cortex increased(P<0.01),and the relative expression level of TDP-43 protein in the cerebral cortex showed a significant increase(P<0.01);the Iba-1 positive cell percentage increased,while the MBP positive cell percentage decreased(P<0.01);the relative expression levels of TNF-α,HMGB1,and TLR4 proteins increased(P<0.05).Compared to the model group,the EA group showed an increased total movement distance(P<0.01),and a reduced escape latency,and more platform crossings in the MWM,with statistically significant differences(P<0.05).In the EA group,neurons showed improvement,with reduced degeneration and necrosis,and larger,clearer nuclei;the percentage of TDP-43 immunofluorescence positive cells in the M1 region of the cerebral cortex decreased(P<0.05),and the relative expression level of TDP-43 protein also decreased(P<0.05);the percentage of Iba-1 positive cells in the M1 region of the cerebral cortex decreased,while the percentage of MBP positive cells increased(P<0.01);the relative expression levels of TNF-α,HMGB1,and TLR4 proteins decreased(P<0.05).Conclusion:EA intervention can suppress microglial activation,improve the state of oligodendrocytes,and reduce abnormal TDP-43 aggregation in the M1 region of the cerebral cortex in ALS model mice;its mechanism of action may be related to the HMGB1/TLR4 signaling pathway.

Objective:To evaluate the efficacy and safety of nebulized inhalation of recombinant human interferon (IFN) α1b injection in the treatment of respiratory syncytial virus (RSV) associated lower respiratory tract infections (pneumonia and bronchiolitis) in children.Methods:A randomized, double-blind, parallel, placebo-controlled add-on design was used.Children with pneumonia or bronchiolitis aged 2 months to 5 years who tested positive for RSV antigen within 72 hours of onset from 30 clinical trial sites including Beijing Children′s Hospital, Capital Medical University between February 2021 and December 2022 were included in this study and randomly divided into 2 groups at a ratio of 1∶1 based on a stratified-block method.Both groups received basic treatments such as cough control, asthma relieving, expectorant treatment, fever reduction, oxygen therapy, etc.The experimental group received additional nebulized inhalation of IFN α1b injection at a dose of 2.0 μg/(kg·time), twice a day.The control group received nebulized inhalation of placebo twice a day.Clinical efficacy was evaluated based on indicators such as the duration of clinical symptoms and signs, and the Kaplan-Meier method was used to calculate the median and 95% CI of the duration of clinical symptoms and signs.The Log-rank test was used to compared data between groups.Safety was assessed through the incidence of adverse reactions and laboratory tests, and the Chi-square test was used to analyze the difference between groups. Results:There were 123 children in the experimental group and 122 children in the control group.The median durations of all the 5 clinical symptoms and signs [including shortness of breath, wheezing, dyspnea (visible retractions), decreased transcutaneous oxygen saturation, and abnormal mental state] in the experimental group after treatment were slightly shortened than those in the control group [2.7 d(95% CI: 1.9-3.0 d)] vs.[2.9 d(95% CI: 2.6-3.6 d), P=0.027].The improvement in dyspnea (retractions) was especially pronounced in the experimental group, with a relief rate of 50.0% (0, 100%) on the first day of administration[compared with 0 (0, 50.0%) in the control group ( Z=2.002, P=0.025)].The median duration of dyspnea in the experimental group was nearly 1 day shorter than that in the control group [1.0 d(95% CI: 0.7-1.7 d) vs.1.8 d(95% CI: 1.0-2.5 d), P=0.046].There were no significant difference in hospital stay [6.0(5.0, 8.0) d vs.6.5(5.0, 8.0) d, Z=0.675, P=0.500], oxygen therapy duration [32.0(14.0, 96.3) h vs.39.0 (24.0, 83.2) h, Z=0.094, P=0.925], the recovery rate from clinical symptoms during treatment [(105/106, 99.1%) vs.(96/101, 95.0%)], and recurrence rate [(0/106, 0) vs.(2/101, 2.0%)] between the 2 groups (all P>0.05).However, the above-mentioned four indicators in the experimental group showed a trend of clinical benefits.The quantitative virus detection results showed that the RSV viral load in both groups decreased after treatment compared to before treatment.After 2 days of treatment, the decline rate of RSV viral load from the baseline was 0.90 lg copies/(mL·d) in the experimental group and 0.25 lg copies/(mL·d)in the control group, with a statistically significant difference ( P<0.05).Furthermore, there was no statistically significant difference in the incidence of adverse reactions between the 2 groups ( P>0.05).Importantly, no drug-related serious adverse reactions occurred in both groups. Conclusions:The nebulized inhalation therapy of IFN α1b demonstrates efficacy and safety in treating pediatric RSV associated lower respiratory tract infections.It particularly offers outstanding clinical therapeutic value for severe children.

Objective Through in vitro experiments,biomechanical data of the transtibial pullout suture(TPS),tendon reconstruction(TR),and tendon reconstruction with suture augmentation(TRS)were collected,so as to evaluate the biomechanical effectiveness of tendon reconstruction for repairing medial meniscus posterior root tear(MMPRT).Methods Eighteen porcine knee joint models were divided into TPS,TR,and TRS groups.Sutures were used to fix the meniscal root in TPS group.Tendons were passed through an incision at the meniscal root in TR group.Tendons were passed through an incision at the meniscal root and secured at tendon-meniscus contact area with additional sutures in TRS group.The sutures and tendons were pulled out through tibial tunnels and fixed at the anteromedial tibia.All groups underwent failure load tests,and ultimate failure load,displacement at failure load,load at clinical failure,stiffness,and failure modes of the samples were recorded.Results The maximum failure load in TPS group was significantly higher than that in TR group(P＜0.05),but there was no significant difference between TPS group and TRS group(P＞0.05).The maximum failure load in TRS group was significantly higher than that in TR group(P＜0.05).The displacement under failure load in TR group and TRS group was significantly lower than that in TPS group(P＜0.05),but there was no significant difference between TR group and TRS group(P＞0.05).There were no significant differences in the load under clinical failure among the 3 groups(P＞0.05).The stiffness of TRS group was significantly greater than that of TPS group(P＜0.05),but no significant difference was observed between TR group and TPS group,as well as between TR group and TRS group(P＞0.05).All failures were caused by suture or tendon cutting through the meniscus.Conclusions The tendon reconstruction techniques is superior to the TPS in terms of failure displacement and stiffness,while the TRS further enhances the stability of the repair.

Ferroptosis is an emerging form of regulated cell death characterized by iron-dependent lipid peroxidation and the failure of the antioxidant system，which results in iron-dependent oxidative damage to the cell membrane. Ferroptosis is implicated in various biological processes，including cell proliferation，aging，and differentiation. The regulation of oxidative stress by ferroptosis is closely associated with the inactivation of glutathione peroxidase 4（Gpx4），dysfunction of the cysteine/glutamate antiporter System Xc-，the production of reactive oxygen species derived from oxidized polyunsaturated fatty acids，and alterations in lipid metabolism. Oxidative stress is a critical mechanism underlying the onset and progression of benign prostatic hyperplasia（BPH）and plays a pivotal role in its pathogenesis. Ferroptosis may regulate the occurrence and development of BPH by mediating lipid oxidative stress response.
