With the continuous deepening of the concept of precision diagnosis and treatment for lung cancer, how to achieve higher efficiency and accuracy in the screening, diagnosis, and treatment pathways in clinical practice has become an important issue that urgently needs to be overcome. The current clinical difficulty lies in the fact that despite continuous advancements in imaging and molecular diagnostic technologies, there are still limitations in manual efficiency and subjective experience when it comes to massive data analysis and multi-scale feature extraction. Artificial intelligence (AI), especially algorithm systems based on deep learning, is an innovative technology capable of deeply empowering medical big data. This method utilizes algorithms such as convolutional neural networks, combined with radiomics, pathomics, and multi-modal data fusion analysis, demonstrating immense potential in early precise detection and benign-malignant differentiation of pulmonary nodules, digital pathological subtype recognition and non-invasive prediction of driver genes, precise 3D surgical planning and automatic delineation of radiotherapy target volumes, as well as dynamic risk warning during follow-up. This innovative technology provides a brand-new solution for realizing intelligent and individualized lung cancer diagnosis and treatment models. This consensus, based on the latest evidence from evidence-based medicine and combined with the development trends in the AI field and real-world clinical needs, was ultimately formed by gathering the consensus opinions of multidisciplinary experts in radiology, pathology, thoracic surgery, and other fields. The main content covers the application specifications of AI in the three core scenarios of lung cancer screening, diagnosis, and treatment, the technical standards for data collection and algorithm validation, as well as the ethical and regulatory challenges faced at the current stage. It aims to clarify the applicable boundaries of AI as a clinical auxiliary decision support tool, providing scientific guidance and standardized exploration directions for peers currently engaged in or planning to carry out AI-assisted clinical diagnosis, treatment, and translation of lung cancer.

IgG4-related sclerosing cholangitis (IgG4-SC) is an IgG4-related disease charac-terized by bile duct wall thickening and luminal stricture. Its pathogenesis involves complex multi-dimensional regulation, including immune imbalance, genetic epigenetic regulation, microbial ecolo-gical abnormalities, and activation of fibrotic pathways. Due to the lack of specificity in clinical mani-festations, IgG4-SC is easily misdiagnosed as biliary tract diseases such as cholangiocarcinoma and primary sclerosing cholangitis in the early stage, leading to diagnostic difficulties. At present, gluco-corticoids are the preferred treatment option. Although most patients can quickly recover in the early stages, high recurrence rates and hormone dependence limit the long-term effectiveness of treatment. The authors combine the latest research progress at home and abroad to deeply analyze the pathogenesis, clinical manifestations, and diagnosis of IgG4-SC, focusing on treatment strategies and cutting-edge advances, in order to provide reference and inspiration for clinical practice.

BACKGROUND: The sirtuin family is well recognized for its crucial involvement in various cellular processes. Nevertheless, studies on its role in the human endometrium are limited. This study aimed to explore the expression and localization of the sirtuin family in the human endometrium, focusing on sirtuin 3 (SIRT3) and its potential role in the oxidative imbalance of the endometrium in polycystic ovary syndrome (PCOS). METHODS: Endometrial specimens were collected from both patients with PCOS and controls undergoing hysteroscopy at the Center for Reproductive Medicine, Peking University Third Hospital, from July to August 2015 and used for cell culture. The protective effects of SIRT3 were investigated, and the mechanism of SIRT3 in improving endometrial receptivity of patients with PCOS was determined using various techniques, including cellular bioenergetic analysis, small interfering ribonucleic acid (siRNA) silencing, real-time quantitative polymerase chain reaction, Western blot, immunofluorescence, immunohistochemistry, and flow cytometry analysis. RESULTS: The sirtuin family was widely expressed in the human endometrium, with SIRT3 showing a significant increase in expression in patients with PCOS compared with controls ( P <0.05), as confirmed by protein and gene assays. Concurrently, endometrial antioxidant levels were elevated, while mitochondrial respiratory capacity was reduced, in patients with PCOS ( P <0.05). An endometrial oxidative stress (OS) model revealed that the downregulation of SIRT3 impaired the growth and proliferation status of endometrial cells and reduced their receptivity to day 4 mouse embryos. The results suggested that SIRT3 might be crucial in maintaining normal cellular state by regulating antioxidants, cell proliferation, and apoptosis, thereby contributing to enhanced endometrial receptivity. CONCLUSIONS Our findings proposed a significant role of SIRT3 in improving endometrial receptivity in patients with PCOS by alleviating OS and regulating the balance between cell proliferation and apoptosis. Therefore, SIRT3 could be a promising target for predicting and improving endometrial receptivity in this patient population.

There is limited evidence to support the use of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in solid organ transplants (SOTs). This systematic review and meta-analysis aimed to assess the safety and efficacy of GLP-1RAs in this population. PubMed, Embase, and Cochrane databases were a thorough literature search until July 2024 for SOTs with pre- and posttransplant diabetes mellitus (DM). Hemoglobin A1c (HbA1c), weight, and body mass index (BMI) were the primary outcomes. We estimated odds ratios and standardized mean difference (SMD) or mean difference (MD) with 95% confidence interval (CI) for dichotomous and continuous outcomes, respectively. I2 statistics measured heterogeneity. GLP-1RAs were administered to 806 subjects (99.8%) in 16 trials. Median follow-up was 12 months (interquartile range, 1–49 months). The mean age was 57.05 ± 10.24 years, with 64.6% male patients. HbA1c levels (MD, –0.61% [95% CI, –0.82 to –0.40]; p < 0.01, I2 = 72%), weight, and BMI were statistically significantly reduced. Estimated glomerular filtration rate (eGFR; SMD, –0.38 mL/min/1.73 m2 [95% CI, –1.01 to 0.25]; p = 0.24, I2 = 0%), creatinine, and blood pressure did not change significantly. Additionally, total daily insulin dosage, lipid profile, fasting plasma glucose, and urine albumin-to-creatinine ratio and tacrolimus levels (MD, –0.40 ng/mL [95% CI, –0.85 to 0.05]; p = 0.08, I2 = 42%) did not yield statistically significant. GLP-1RAs caused increased nausea and vomiting (13.9%), urinary tract infections (21.1%), and drug discontinuation (13.4%). In SOT recipients, GLP-1RAs significantly reduced HbA1c, weight, and BMI without significantly altering tacrolimus trough levels, eGFR, creatinine, or cardiovascular outcomes. Gastrointestinal side effects were the most common adverse events.

ObjectiveTo evaluate the effect of women's body mass index （BMI） on pregnancy outcomes of ovulation induction intrauterine insemination （OI-IUI） in patients with unexplained primary infertility. MethodsThe study included 764 OI-IUI cycles from January 2016 to December 2022 in reproductive center of Sun Yat-sen Memorial Hospital. According to BMI，patients were divided into three groups：low BMI （BMI<18.5 kg/m²）， normal BMI （18.5 kg/m² ≤BMI＜23.0 kg/m²）， and high BMI （BMI≥23.0 kg/m²）. Comparison of clinical data and pregnancy outcomes was performed between the groups. Logistic regression was used to analyze the association between BMI and live birth rate. ResultsFrom the low BMI group to the high BMI group， the HCG positive rate （7.08%，9.74%， 13.19%）， clinical pregnancy rate（5.51%， 7.91%， 13.19%）， and live birth rate （4.72%， 6.90%， 12.50%） increased. Among them， the live birth rate of the high BMI group was significantly higher than that of the low BMI group and the normal BMI group， with a statistically significant difference （P=0.034）. While the early miscarriage rate （14.28%， 10.26%， 5.26%） decreased from the low BMI group to the high BMI group. The binary logistic regression analysis revealed that BMI was an independent factor in live birth， and high BMI resulted in a better live birth rate than low BMI （OR=3.15，95%CI=1.191-8.329，P=0.021）. ConclusionLow BMI is associated with poor OI-IUI outcomes in patients with unexplained primary infertility. These patients are encouraged to gain weight in a healthy manner.

The incidence and detection rates of benign and low-grade malignant pancreatic tumors have risen yearly.For patients with such tumors,traditional radical resection procedures often result in excessive loss of normal pancreatic parenchyma,leading to complications such as postoperative insufficiency of both exocrine and endocrine functions.Studies have shown that functional-preserving surgeries,such as minimally invasive enucleation or partial resection surgeries,can maximize the protection of patients'pancreatic function and improve long-term quality of life.However,for some tumors deep within the pancreatic parenchyma,accurately locating the tumor and protecting the pancreatic duct pose challenges.Intraoperative ultrasound(IOUS)has become an ideal intraoperative imaging tool,often referred to as the surgeon's"third eye"because of its portability,ability to provide real-time high-resolution information,non-reliance on ionizing radiation,and the fact that it does not require special patient preparation.With advancements in technology,the application scope of IOUS has expanded beyond its initially limited diagnostic role to various surgical applications,including identifying non-palpable lesions,guiding surgical strategies,and staging tumors.In the current era of minimally invasive and precision surgery,the proficiency of surgeons in using IOUS has become an important issue.This article reviews the history of IOUS applications,summarizes the advantages and basic usage methods of robotic IOUS,and shares techniques for applying IOUS in robot-assisted precise resection of pancreatic tumors.

Atopic dermatitis (AD) is a chronic inflammatory skin condition. Natural products have gained traction in AD treatment due to their accessibility, low toxicity, and favorable pharmacological properties. However, their application is primarily constrained by poor solubility, instability, and limited permeability. The transdermal drug delivery system (TDDS) offers potential solutions for transdermal delivery, enhanced penetration, improved efficacy, and reduced toxicity of natural drugs, aligning with the requirements of modern AD treatment. This review examines the application of hydrogels, microneedles (MNs), liposomes, nanoemulsions, and other TDDS-carrying natural products in AD treatment, with a primary focus on their effects on penetration and accumulation in the skin. The aim is to provide valuable insights into the treatment of AD and other dermatological conditions.

Abstract: Objective　To investigate the early diagnostic value of peripheral blood procalcitonin (PCT), C-reactive protein (CRP), fibrinogen (FIB) and D-dimer (D-D) levels in patients with pulmonary tuberculosis (PTB) complicated with bacterial pneumonia. Methods　A total of 102 patients who admitted to Department of Tuberculosis of Affiliated Nantong Hospital of Shanghai University from Jan 2021 to May 2022 were enrolled in this study and divided into a group (52 cases) with pulmonary tuberculosis (PTB) patients and a group (50 cases) with PTB patients complicated with bacterial pneumonia. The levels of PCT, CRP, FIB and D-D in the peripheral blood were measured, the differences and correlations in all indicators were compared among two groups. The sensitivity and specificity of these indicators in the early diagnosis of PTB complicated with bacterial pneumonia were analyzed by receiver operating characteristic (ROC) curve. Results　The levels of PCT, CRP, FIB and D-D in the peripheral blood from the PTB complicated with bacterial pneumonia group were 0.06 (0.04, 0.16) ng/mL, 38.00 (3.88, 96.10) mg/L, 4.51 (3.02, 6.07) g/L, and 0.59 (0.34, 1.88) mg/L, respectively, which were significantly higher than corresponding 0.04 (0.03, 0.04) ng/mL, 3.20 (0.84, 7.22) mg/L, 2.96 (2.48, 3.77) g/L, and 0.27 (0.17, 0.36) mg/L in the PTB group (Z=-4.784, -5.233, -3.853, -4.199, all P<0.001). Furthermore, the levels of CRP and FIB in the PTB complicated by bacterial pneumonia group were highly positively correlated (r=0.855, P<0.001). The area under the ROC curve (AUC) of PCT, CRP, FIB and D-D for early diagnosis of PTB complicated with bacterial pneumonia were 0.757, 0.794, 0.747 and 0.764, respectively. In addition, the AUC obtained by simultaneous measurement of PCT, CRP, FIB and D-D was as high as 0.916, and the sensitivity and specificity of diagnosing PTB complicated with bacterial pneumonia were increased to 85.7% and 96.9%, respectively, which were higher than those of individual indicators. Conclusions　Levels of peripheral blood PCT, CRP, FIB, and D-D all show varying degrees of increase in patients with PTB complicated with bacterial pneumonia, and detecting the levels of all four markers, rather than any single marker, can assist in early monitoring whether the tuberculosis patients are complicated with bacterial pneumonia.
