Objective To construct a lung cancer surgery-oriented disease-specific database covering the entire perioperative care pathway, thereby improving the quality and usability of key surgical data elements. Methods Real-world clinical data were extracted from a single-center thoracic surgery department. A standardized data model was established based on the open electronic health record (openEHR) standard. Large language model (LLM), optical character recognition (OCR), and artificial intelligence (AI)-driven techniques were employed to extract, structure, and perform quality control on unstructured clinical narratives, imaging reports, and radiological data, with a focus on capturing surgically relevant perioperative indicator. Results A multimodal database comprising 19 917 patients was established, including 7 930 males and 11 987 females, with ages ranging from 15 to 97 (61.7±9.7) years. The database includes 582 structured data variables, textual report data corresponding to 69 clinical indicators, 13 000 pulmonary function test PDF reports, and chest CT imaging data from 16 884 patients. This database comprehensively covers major information relevant to surgical diagnosis and treatment of lung cancer, significantly improving the completeness and granularity of surgical detail data. Large language models (LLMs) and optical character recognition (OCR) technologies enhanced the efficiency of converting unstructured data into structured formats, while a multi-level manual verification process ensured data accuracy and traceability. The database supports real-world research including comparisons of surgical procedures, prediction of postoperative complications, prognosis assessment, and multimodal data association analyses.

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.

BACKGROUND: Alpha-glucosidase inhibitors or dipeptidyl peptidase-4 inhibitors are both hypoglycemia agents that specifically impact on postprandial hyperglycemia. We compared the effects of acarbose and sitagliptin add on to metformin on time in range (TIR) and glycemic variability (GV) in Chinese patients with type 2 diabetes mellitus through continuous glucose monitoring (CGM). METHODS: This study was a randomized, open-label, active-con-trolled, parallel-group trial conducted at 15 centers in China from January 2020 to August 2022. We recruited patients with type 2 diabetes aged 18-65 years with body mass index (BMI) within 19-40 kg/m 2 and hemoglobin A1c (HbA1c) between 6.5% and 9.0%. Eligible patients were randomized to receive either metformin combined with acarbose 100 mg three times daily or metformin combined with sitagliptin 100 mg once daily for 28 days. After the first 14-day treatment period, patients wore CGM and entered another 14-day treatment period. The primary outcome was the level of TIR after treatment between groups. We also performed time series decomposition, dimensionality reduction, and clustering using the CGM data. RESULTS: A total of 701 participants received either acarbose or sitagliptin treatment in combination with metformin. There was no statistically significant difference in TIR between the two groups. Time below range (TBR) and coefficient of variation (CV) levels in acarbose users were significantly lower than those in sitagliptin users. Median (25th percentile, 75th percentile) of TBR below target level <3.9 mmol/L (TBR 3.9 ): Acarbose: 0.45% (0, 2.13%) vs . Sitagliptin: 0.78% (0, 3.12%), P = 0.042; Median (25th percentile, 75th percentile) of TBR below target level <3.0 mmol/L (TBR 3.0 ): Acarbose: 0 (0, 0.22%) vs . Sitagliptin: 0 (0, 0.63%), P = 0.033; CV: Acarbose: 22.44 ± 5.08% vs . Sitagliptin: 23.96 ± 5.19%, P <0.001. By using time series analysis and clustering, we distinguished three groups of patients with representative metabolism characteristics, especially in GV (group with small wave, moderate wave and big wave). No significant difference was found in the complexity of glucose time series index (CGI) between acarbose users and sitagliptin users. By using time series analysis and clustering, we distinguished three groups of patients with representative metabolism characteristics, especially in GV. CONCLUSIONS: Acarbose had slight advantages over sitagliptin in improving GV and reducing the risk of hypoglycemia. Time series analysis of CGM data may predict GV and the risk of hypoglycemia.

Objective:To learn about the epidemic characteristics of human brucellosis in Baoji City, and to identify brucellosis strains, so as to provide scientific basis for precise prevention and control of brucellosis in the city.Methods:A retrospective analysis method was used to conduct a descriptive epidemiological analysis of brucellosis cases in Baoji City reported in the China Disease Prevention and Control Information System from 2009 to 2022. Bacteriology culture, serum agglutination, biochemical test, phage cleavage and PCR were used to identify the isolates and nucleic acids, respectively.Results:From 2009 to 2022, a total of 314 cases of human brucellosis were reported in Baoji City, with an average annual incidence rate of 0.62/100 000, The incidence rate of different years was compared, the difference was statistically significant (χ 2 = 51 748 520.36, P < 0.001). The gender ratio of male to female was 3.30 ∶ 1.00 (241 ∶ 73). The age distribution ranged from 2 to 84 years old, with a median of 50 years old. The cases were concentrated in the 30 - 59 age group (206 cases, 65.61%), followed by the 60 - 84 age group (80 cases, 25.48%) and the 2 - 29 age group (28 cases, 8.92%). The peak of incidence was from April to August, with a total of 205 cases, accounting for 65.29%. Cases were reported in 213 townships, with the number of townships increasing from 1 in 2009 to 29 in 2022. The median time interval between onset and diagnosis of the case was 11 days. There was no significant difference in the time interval between onset and diagnosis among different genders, occupation and regions ( P > 0.05). A total of 10 strains of Brucella were isolated and identified as Brucella genus by BCSP31-PCR, and as Brucella melitensis by AMOS-PCR. After comprehensive identification, 4 strains were Brucella melitensis 3, 3 strains were mutant Brucella melitensis, and 3 strains were Brucella melitensis 1. Conclusion:The epidemic of brucellosis in Baoji City shows a fluctuating upward trend, with the epidemic scope gradually expanding, and the infected strains are all Brucella melitensis.

Objective:To describe the positive rates of high-risk human papillomavirus (HR-HPV) DNA and serum-neutralizing antibody in cervical intraepithelial neoplasia (CIN) tissues of rural women in Xiangyuan County, Shanxi Province, and evaluate the association of HR-HPV DNA and neutralizing antibody positive status with the occurrence of CIN.Methods:In a cohort of 1 897 women aged 35-45 years established by the Shanxi Province Cervical Cancer Screening StudyⅠ, DNA typing (SPF10 PCR-DEIA-LiPA25) was performed by using tissue samples of women with positive HR-HPV test results [Hybrid CaptureⅡ(HC2)] or abnormal cytological or pathological results. Serum HR-HPV neutralizing antibody detection was conducted with multicolor pseudovirion-based neutralization assay. Cochran-Armitage trend test was used to analyze the changing trend of the positive rate of HR-HPV DNA and neutralizing antibody with the progression of CIN. Multivariate logistic regression models were used to evaluate the influence and multiplicative interaction of HR-HPV DNA and neutralizing antibody positive status on the occurrence of CIN. The relative excess risk ( RERI), attributable proportion of interaction ( AP), and the synergy index ( SI) of the interaction were calculated to evaluate the additive interaction of HR-HPV DNA and neutralizing antibody on the occurrence of CIN. Results:The positive rate of any type of HR-HPV DNA (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68) in 479 women who were HC2 positive or had abnormal cytological or pathological detection results was 37.16%. In normal, CIN1, CIN2, and CIN3+ groups, the HR-HPV DNA positive rates were 18.03%, 49.53%, 90.24% and 94.59%, respectively. The positive rate of any type of HR-HPV neutralizing antibody was 63.88%. In normal, CIN1, CIN2, and CIN3+ groups, the positive rates of HR-HPV neutralizing antibody were 63.95%, 57.94%, 70.73%, and 72.97%, respectively. The positive rate of any type of HR-HPV neutralizing antibody was 53.31% in 1 418 women who were HC2 negative and had normal cytopathology, and the most common types were HPV51 (27.36%) and HPV39 (24.96%). Multivariate logistic regression analysis showed that any type of HR-HPV DNA positive status ( OR=9.15, 95% CI: 5.99-14.20, P<0.001) was the independent factor for the occurrence of CIN, HR-HPV neutralizing antibody positive status was not associated with the occurrence of CIN ( OR=0.95, 95% CI: 0.61-1.48, P=0.815). The OR value of the multiplication of HR-HPV DNA and neutralizing antibody positive status of the occurrence of CIN was 1.63 (95% CI: 0.67-3.95), P=0.283. Quantitative analysis of interaction showed that RERI was 1.65 (95% CI:-3.56-6.86), SI was 1.28 (95% CI: 0.58-2.82), and AP was 0.19 (95% CI:-0.36-0.75). Conclusions:HR-HPV DNA positive status was a risk factor for the occurrence of CIN, but neutralizing antibody positive status was not associated with the occurrence of CIN. They had no significant multiplicative or additive interaction with the occurrence of CIN.

Objective To analyze the relationship between serum angiopoietin-like protein 8(ANGPTL8)and semaphorin 3A(Sema 3A)levels and postoperative cerebral vasospasm(CVS)in patients with intracranial aneurysm(IA)rupture.Methods A total of 188 patients with IA rupture receiving surgical treatment in our hospital were prospectively selected during October 2021 and October 2023,and according to whether CVS occurred after surgery,they were classified into a spasm group(75 cases)and a non-spasm group(113 cases).Serum ANGPTL8 and Sema 3A levels were measured after admission.Spearman correlation analysis was performed to assess the correlation of the levels with CVS occurrence.Binary logistic regression analysis was applied to construct a prediction model with serum ANGPTL8 and Sema 3A as variables.ROC curve was plotted to evaluate the predictive value of the levels for postoperative CVS.Results The serum ANGPTL8 level was significantly higher while that of Sema 3A was obviously lower in the spasm group then the non-spasm group(P＜0.01).Binary logistic regression analysis showed that the levels of serum ANGPTL8 and Sema 3A were independent predictors of postoperative CVS in patients with ruptured IA(OR=1.021,95％CI:1.013-1.029,P=0.000;OR=0.980,95％CI:0.967-0.993,P=0.003).ROC curve analysis indicated that the AUC value,sensitivity and speci-ficity of the two indicators combined together in predicting postoperative CVS was 0.939(95％CI:0.894-0.969),89.33％and 89.38％,respectively,with better predictive efficiency than each indicator alone(P＜0.01).Conclusion Serum ANGPTL8 and Sema 3A levels are closely associat-ed with postoperative CVS in patients with IA rupture,and they can be used as effective indicators for early prediction of postoperative CVS.

OBJECTIVE: To investigate the load distribution on the more painful and less painful limbs in patients with mild-to-moderate and severe bilateral knee osteoarthritis (KOA) and explore the compensatory mechanisms in both limbs among bilateral KOA patients with different severity levels. METHODS: A total of 113 participants were enrolled between July 2022 and September 2023. This cohort comprised 43 patients with mild-to-moderate bilateral KOA (Kellgren-Lawrence grade 2-3), 43 patients with severe bilateral KOA (Kellgren-Lawrence grade 4), and 27 healthy volunteers (healthy control group). The visual analogue scale (VAS) score for pain, the Hospital for Special Surgery (HSS) score, passive knee range of motion (ROM), and hip-knee-ankle angle (HKA) were used to assess walking pain intensity, joint function, and lower limb alignment in KOA patients, respectively. Motion trajectories of reflective markers and ground reaction force data during walking were captured using a gait analysis system. Musculoskeletal modeling was then employed to calculate biomechanical parameters, including the peak knee adduction moment (KAM), KAM impulse, peak joint contact force (JCF), and peak medial/lateral contact forces (MCF/LCF). Statistical analyses were performed to compare differences in clinical and gait parameters between bilateral limbs. Additionally, one-dimensional statistical parametric mapping was utilized to analyze temporal gait data. RESULTS: Mild-to-moderate KOA patients showed the significantly higher HSS score (67.7±7.9) than severe KOA patients (51.9±8.9; t=8.747, P<0.001). The more painful limb in all KOA patients exhibited significantly greater HKA and higher VAS scores compared to the less painful limb ( P<0.05). While bilateral knee ROM did not differ significantly in mild-to-moderate KOA patients ( P>0.05), the severe KOA patients had significantly reduced ROM in the more painful limb versus the less painful limb ( P<0.05). Healthy controls showed no significant bilateral difference in any biomechanical parameters ( P>0.05). All KOA patients demonstrated longer stance time on the less painful limb ( P<0.05). Critically, severe KOA patients exhibited significantly higher peak KAM, KAM impulse, and peak MCF in the more painful limb ( P<0.05), while mild-to-moderate KOA patients showed the opposite pattern with lower peak KAM and KAM impulse in the more painful limb ( P<0.05) and a similar trend for peak MCF. CONCLUSION Patients with mild-to-moderate KOA effectively reduce load on the more painful limb through compensatory mechanisms in the less painful limb. Conversely, severe bilateral varus deformities in advanced KOA patients nullify compensatory capacity in the less painful limb, paradoxically increasing load on the more painful limb. This dichotomy necessitates personalized management strategies tailored to disease severity.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.
