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.

Pancreatic cancer is a kind of highly malignant tumor with a low survival rate and poor prognosis. The effectiveness of gemcitabine as a first-line chemotherapy drug is limited; however, it can activate dendritic cells and improve antigen presentation which increase the sensitivity of tumor cell to immunotherapy. Although immunotherapy has made some advancements in cancer treatment, the therapeutic benefit of programmed cell death receptor 1/programmed death receptor-ligand 1 (PD-1/PD-L1) blockade therapy remains relatively low. The chemokine C-X-C chemokine ligand 12 (CXCL12) contributes to an immunosuppressive tumor microenvironment by recruiting immunosuppressive cells. The receptor C-X-C motif chemokine receptor 4 (CXCR4), highly expressed in various tumors including pancreatic cancer, plays a crucial role in tumor development and progression. In this study, the anti-tumor immune response of human peripheral blood mononuclear cell (hPBMC) was enhanced using the combination of BsNb PX4 (anti-PD-L1&CXCR4 bispecific nanobody) and gemcitabine. In a co-culture system of gemcitabine-pretreated hPBMCs with tumor cells, the BsNb PX4 synergized gemcitabine to improve the cytotoxic activity of hPBMCs against tumor cells. Flow cytometry analysis confirmed increased ratio of CD8⁺ to CD4⁺ T cells in combination treatment. In NOD/SCID mice bearing pancreatic cancer, the combination treatment exhibited more infiltration of CD8⁺ T cells into tumor tissues, contributing to an effective anti-tumor response. This study presents potential new therapies for the treatment of pancreatic cancer. Ethical approval was obtained for collection of hPBMC samples from the Local Ethics Committee of Shanghai Jiao Tong University. All animal experiments were approved by the Animal Ethic Committee of Shanghai Jiao Tong University (authorizing number: A2024246).

Background: and Purpose Ruptured intracranial aneurysms (RIA) are associated with a mortality rate of up to 40% in the Chinese population, highlighting the critical need for targeted treatment interventions for at-risk individuals. Although the impact of aldehyde dehydrogenase 2 (ALDH2) gene mutations on susceptibility to intracranial aneurysms (IA) is well documented, the potential connection between ALDH2 rs671 single-nucleotide polymorphism (SNP) and RIA remains unexplored. Given the increased prevalence of ALDH2 gene mutations among Chinese Han individuals, it is clinically relevant to investigate the link between ALDH2 rs671 SNP and IA rupture. Methods: A prospective study was conducted on 546 patients diagnosed with IA to investigate the association between ALDH2 rs671 SNP and the risk of IA rupture. Results: The ALDH2 rs671 SNP (ALDH2*2) was significantly more prevalent in patients with unruptured IA (UIA) than in those with RIA (32.56% vs. 18.58%, P=0.004). Multivariate logistic regression analysis revealed that people with the ALDH2 mutation (ALDH2*1/*2 and ALDH2*2/*2 gene type) had a significantly reduced odds ratio (OR=0.49; 95% confidence level [CI] 0.27–0.88; P=0.018) for RIAs. Age-specific subgroup analysis indicated that the ALDH2 mutation provided a stronger protective effect in individuals aged 60 years and above with IA compared to those under 60 years old (OR=0.38 vs. OR=0.52, both P<0.05). Conclusion The incidence of RIA was significantly higher in individuals with a normal ALDH2 gene (ALDH2*1/*1) than in those with an ALDH2 rs671 SNP (ALDH2*1/*2 or ALDH2*2/*2). ALDH2 rs671 SNP may serve as a protective factor against RIA in the Chinese Han population.

Non-infectious chronic diseases in human including diabetes, non-alcoholic fatty liver disease (NAFLD), atherosclerosis (AS), neurodegenerative diseases, osteoporosis, as well as malignant tumors may have some common pathogenic mechanisms such as non-resolved inflammation (NRI), gut microbiota dysfunction, endoplasmic reticulum stress, mitochondria dysfunction, and abnormality of the mammalian target of rapamycin (mTOR) pathway. These pathogenic mechanisms could be the basis for "homotherapy for heteropathy" in clinic. Some commonly used clinical drugs, such as metformin, berberine, aspirin, statins, and rapamycin may execute therapeutic effect on their targeted diseases,and also have the effect of "homotherapy for heteropathy". The mechanisms of the above drugs may include anti-inflammation, modulation of gut microbiota, suppression of endoplasmic reticulum stress, improvement of mitochondria function, and inhibition of mTOR. For virus infectious diseases, as some viruses need certain commonly used replicases, the inhibitors of the replicases become examples of "homotherapy for heteropathy" for antiviral therapy in clinic (for example tenofovir for both AIDS and HBV infection). Especially, in case of outbreak of new emerging viruses, these viral enzyme inhibitors such as azvudine and sofibuvir, could be rapidly used in controlling viral epidemic or pandemic, based on the principle of "homotherapy for heteropathy". In this review article, we show the research progress of the biological basis for "homotherapy for heteropathy" and the possible mechanisms of some well-known drugs, in order to provide insights and new references for innovative drug R&D.

The establishment of an economic operating mechanisms for hospitals is a key factor in advancing the growth of public hospitals in the modern age.At present,the due value of key factors such as medical resources and labor value of medical personnel in public hospitals in China has not been fully reflected,which not only restricts the overall operation efficiency of hospitals,but also makes it difficult to realize the marginal value of hospital operation and management.The economic operating mechanisms of public hospitals is in urgent need of reform.Large public hospitals in Henan Province has established an economic operating mechanisms of public hospitals based on intelli-gent finance,comprehensive budget management as the core,and cost control and performance management as the major tools to realize the interconnection of various systems and promote the high-quality development of hospi-tals with the three major supports of industry and finance integration,financial integration and financial integration.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective To construct a nomogram model for predicting the risk of in-hospital death in CHF patients by using noninvasive hemodynamic monitoring combined with age,DBP,CRP and renal insufficiency(serum creatinine≥ 442 μmol/L).Methods A total of 223 elderly patients with acute onset of CHF admitted in First,Second Medical Centre of Chinese PLA General Hos-pital from September 2022 to March 2023 were recruited in this study.According to their clinical outcomes,they were divided into survival group(196 cases)and death group(27 cases).Based on the in-hospital death and other related indicators,a nomogram model was constructed to predict the risk factors of in-hospital death in CHF.Results Noninvasive hemodynamic mornitoring indi-cated that the death group had significantly higher LVEF and LCWI values but lower LVEDV value than the survival group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that age(OR=1.131,95％CI:1.052-1.213,P=0.001),DBP(OR=0.932,95％CI:0.882-0.982,P=0.011),CRP(OR=1.171,95％CI:1.021-1.352,P=0.024),LVEDV(OR=0.984,95％CI:0.962-0.992,P=0.011)and renal insufficiency(OR=5.863,95％CI:1.351-1.731,P=0.004)were independent risk factors for the short-term prognosis of the elderly CHF patients.The AUC value of the nomogram model was 0.902(95％CI:0.819-0.948,P＜0.05),and calibration curve analysis showed the C-index was 0.902,indicating accurate predictive perform-ance.Conclusion Age,DBP,LVEDV,CRP and renal insufficiency are independent risk factors for the short-term prognosis of the elderly CHF patients.

ObjectiveTo explore the potential mechanism of Zuogui Jiangtang Jieyu Formula （左归降糖解郁方， ZJJF） for diabetic rats with depression. MethodsSixty rats were randomly divided into normal group， model group， wingless MMTV integration site family member 5a （Wnt5a） agonist group， ZJJF group， and ZJJF plus Wnt5a inhibitor group， with 12 rats in each group. Except for the normal group， the rats were fed with high-fat chow， streptozotocin injection， and chronic mild unpredictable stress combination， to establish model of diabetes mellitus complicated with depression. After successful modelling， rats in the Wnt5a agonist group were given bilateral hippocampal stereotactic injections of Wnt5a agonist Foxy-5 with 5 μl each for 7 consecutive days； rats in ZJJF group were given 20.52 g/（kg·d） of ZJJF by gavage； rats in ZJJF plus Wnt5a inhibitor group were given the drug by gavage， and bilateral hippocampal stereotactic injections of Wnt5a inhibitors Box5， with the same dosage and injection method as above. The normal group and model group were given 10 ml/（kg·d） of normal saline by gavage. All groups were gavaged for 4 consecutive weeks. At the end of the intervention， the depression-like behaviour of rats was evaluated using the forced swimming experiment （immobility time） and the absent field experiment （number of activities）； the blood glucose and insulin levels of rats were measured and the insulin resistance index was calculated； the dendritic morphology of dentate gyrus neurons in the hippocampus was observed using Golgi staining； the level of dentate gyrus neuron proliferation was measured using 5-bromodeoxyuracil nucleoside （Brdu） injection and immunofluorescence； RT-qPCR and Western blot were used to detect the mRNA and protein expression of Wnt5a， Ras homologue genomic member A （RhoA） and Rho homologue-associated coiled-coil protein kinase 1 （ROCK1） in the dentate gyrus. ResultsCompared with the normal group， rats in the model group had significantly higher blood glucose， insulin and insulin resistance indices， longer immobility time， fewer activities， lower Brdu integral optical density values and Wnt5a， RhoA， ROCK1 protein and mRNA expression in the dentate gyrus of the hippocampus （P＜0.05 or P＜ 0.01）； the dendritic branches of rat hippocampal dentate gyrus neurons could be seen to be significantly reduced or broken， and their length shortened. Compared with the model group， the blood glucose， insulin and insulin resistance indices of rats in ZJJF group and the ZJJF plus Wnt5a inhibitor group significantly reduced （P＜0.05 or P＜0.01）； the immobility time of rats in the Wnt5a agonist group and ZJJF group was significantly shortened， the number of activities increased， the Brdu integral optical density values elevated， and the Wnt5a， RhoA， ROCK1 protein and mRNA expression elevated （P＜0.05 or P＜0.01）， and the number of dendritic branches of hippocampal dentate gyrus neurons significantly increased， the length lengthened， and the complexity of dendrites increased. Compared with the Wnt5a agonist group， rats in the ZJJF group showed significant decrease in blood glucose， insulin and insulin resistance indices， prolongation of immobilisation time， reduction in the number of activities， and reduction in the Brdu integral optical density value； except for the Wnt5a mRNA in ZJJF group， Wnt5a， RhoA， ROCK1 protein and mRNA expression reduced in both ZJJF group and ZJJF plus Wnt5a inhibitor group （P＜0.05 or P＜0.01）. Compared with ZJJF group， Wnt5a， RhoA， ROCK1 protein and mRNA expression were reduced in ZJJF plus Wnt5a inhibitor group （P＜0.05 or P＜0.01）. ConclusionZJJF can improve hyperglycemia and depressive-like behaviours in rat models of diabetes with depression， and its antidepressant effects may be related to the activation of hippocampal Wnt5a/RhoA signaling and promotion of dentate gyrus neuron dendritic growth.
