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.

ObjectiveThis study aims to analyze animal models of anxiety disorder based on the clinical characteristics of anxiety disorder in traditional Chinese and Western medicine， systematically assess the clinical compatibility， and provide suggestions for the construction of animal models with a high degree of clinical compatibility between traditional Chinese and Western medicine. MethodsRelevant literature on animal models of anxiety disorder was retrieved from global databases. Scoring scales were developed according to the etiology， pathogenesis， and diagnostic criteria of anxiety disorder in both traditional Chinese and Western medicine. The animal models of anxiety disorder in the literature were analyzed， and their clinical compatibility was systematically assessed to identify reference-worthy models. ResultsThe average clinical compatibility of existing animal models of anxiety disorder was 42.13% for traditional Chinese medicine and 50.94% for Western medicine. Among these， the chronic unpredictable mild stress （CUMS） model had the highest compatibility with both traditional Chinese and Western medicine. However， current models rarely reflect the clinical syndromes of traditional Chinese medicine in depth， and show limitations in syndrome differentiation. ConclusionThe existing animal models of anxiety disorder are mostly established using single-factor approaches， which fail to comprehensively simulate the onset process and physiopathological characteristics of anxiety disorder. These models also neglect the syndrome-based indicators emphasized in traditional Chinese medicine. In the future， the model development should incorporate the clinical characteristics of syndromes in both traditional Chinese and Western medicine， establish standardized evaluation criteria for anxiety disorder models， and utilize multifactorial approaches to enhance the representativeness of animal models in traditional Chinese medicine.

The advancement of tissue clearing technology has significantly propelled neuroscience research. Nevertheless, the fluorescent proteins used in traditional transgenic mouse strains were not specifically optimized for tissue clearing procedures, resulting in a substantial decrease in fluorescent intensity after clearing. In this study, we developed the Ci1 reporter mouse strain (where Ci stands for the Chinese Institute for Brain Research, CIBR) based on the bright red fluorescent protein mScarlet. The Ci1 reporter exhibits no fluorescence leakage in various organs or tissue types and can be readily crossed with multiple tissue-specific Cre lines. Compared to the Ai14 mouse strain, the Ci1 reporter strain demonstrates lower non-specific leakage, stronger fluorescence intensity in different tissues, and better preservation of fluorescence following tissue clearing treatment. The creation of the Ci1 reporter provides a more effective tool for both neuroscience and other biomedical research applications.

Hepatic ascites is one of the common and difficult complications in the decompensated stage of liver cirrhosis， and its incidence is increasing. In clinical practice， the prognosis of patients with hepatic ascites after surgery is worse， and the disease is recurrent. Traditional Chinese medicine （TCM） has certain advantages in treating hepatic ascites. However， there is no uniform standard for the preparation of animal models of hepatic ascites in accordance with TCM evidence. Therefore， this paper summarized the literature on animal models of hepatic ascites and analyzed the existing animal models of hepatic ascites based on the clinical diagnostic criteria of hepatic ascites in TCM and western medicine. The results show that the commonly used modeling methods for hepatic ascites mainly include the single-factor method， composite factor induction method， surgical method， and immunization method. Most of them are guided by western medicine theories， and their pathogenic mechanisms are mostly consistent with those of western medicine and are different from TCM evidence. Therefore， it is suggested that TCM intervening factors should be imposed in the process of model preparation， so as to prepare an animal model of hepatic ascites that meets the clinical evidence characteristics of TCM and western medicine.

Post-stroke depression is a common complication after a stroke. Based on the theory of ＂deficiency of heart qi leading to sadness＂recorded in Huangdi Neijing, our team proposes that deficiency of heart qi is the basic pathogenesis of post-stroke depression, with sadness being its main manifestation. Therefore, we advocate treating post-stroke depression from the perspective of the heart, and clinically, it can be divided into four stages: heart-liver stage, heart-lung stage, heart-spleen stage, and heart-kidney stage. Treating post-stroke depression with the principle of regulating qi and nourishing the heart, patients in the heart-liver and heart-lung stages are mainly middle-aged and young adults, with a pathological nature of qi stagnation and mild deficiency of heart qi, and therefore, the method of promoting the flow of meridians and regulating qi should be adopted. In contrast, patients in the heart-spleen and heart-kidney stages are mainly middle-aged and elderly, with a pathological nature of qi deficiency and severe deficiency of heart qi, and therefore, nourishment and tonification should be prioritized. In response to the above four stages, our team has achieved good clinical efficacy by administering Xiaoyao Powder, Baihe Dihuang Decoction, Ganmai Dazao Decoction and Jingui Shenqi Pill respectively. This study discusses the approach to treating post-stroke depression from the perspective of a "deficiency of heart qi leading to sadness" by examining three aspects: the theoretical basis of Chinese and Western medicine to treat post-stroke depression from the heart, the basic pathogenesis and staging of post-stroke depression, and the treatment principle of regulating qi and nourishing the heart. The study also briefly analyzes the clinical experience of the medications used for this condition to provide a reference for the treatment of post-stroke depression.

Chaihu Guizhi Decoction is an excellent prescription of ZHANG Zhongjing;however,nowadays the application of Chaihu Guizhi Decoction is primarily derived from the text.The xiang thinking is the source of traditional Chinese medicine thinking.Understanding Chaihu Guizhi Decoction from the xiang thinking,it is easy to perceive the true meaning of ZHANG Zhongjing,and grasp the location of the disease and the patient's overall qi,so as to make better use of this formula.This article discusses the understanding of Chaihu Guizhi Decoction from five perspectives:firstly,it gives an overview of the xiang thinking,pointing out the source and essential value of the xiang thinking;secondly,it analyses the disease position and the patient's qi of Chaihu Guizhi Decoction under the perspective of the xiang thinking as a whole;thirdly,it discusses the disease position and the patient's qi of the original text of Chaihu Guizhi Decoction from the xiang thinking;fourthly,it discusses how to understand the principle of formula formation and the main and minor parts of Chaihu Guizhi Decoction by xiang thinking;finally,it analyses the primary medicines in Chaihu Guizhi Decoction by using xiang thinking based on the records of Shennong Bencao Jing.Based on these five points,we hope to reveal the traditional Chinese medicine thinking behind Chaihu Guizhi Decoction,and provide new ideas for the clinical application of Chaihu Guizhi Decoction.

Objective To investigate the modeling elements of various types of animal models for acute liver injury,and to provide references and suggestions to establish and evaluate animal models of acute liver injury(ALI).Methods The animal experimental literature of ALI from 2002 to 2022 was searched in the databases of the China Knowledge Network,WanFang,Chongqing Vip(VIP),Chinese Medical Journal Full Text Data(Yiigle),and PubMed.The animal species,positive control drugs,modeling method,modeling drugs,and drug administration of the animal models of ALI in the literature were summarized.The result were analyzed using Excel,SPSS Modeler 18.0,and Cytoscape 3.8.2.Results A total of 896 articles were included in the databases.The most used animal models for ALI were male KM mice.The modeling method were mainly chemical liver injury,alcoholic liver injury,drug-related liver injury,and immune liver injury.①The corresponding main modeling method were intraperitoneal injection of 10 mL/kg of 0.1％CC14 in vegetable oil at 24 h before experiments,②gavage of 12.0 mL/kg of 50.0％～56.0％ethanol at 16 h before experiments,③intraperitoneal injection of 300 mg/kg APAP at 24 h before experiments,④tail vein injection of 20 mg/kg Con A at 8 h before experiments.Evaluation of the models was based on liver pathological indexes as the gold standard combined with biochemical indexes of serum ALT,AST,and SOD and MDA contents and activities in liver tissue homogenate as direct indicators.Conclusions Because the causes of ALI vary in clinical practice,the preparation of animal models of ALI should be based on the specific study content and characteristics,and the corresponding modeling method should be selected.

Parkinson's disease is the second most common neurodegenerative disease in middle-aged and elderly people.It is characterized by a long disease course and complex treatment process,introducing great challenges to society.Behavioral changes in animal models of Parkinson's disease can intuitively reflect the modeling situation of experimental animals and the effects of drug interventions.Therefore,selecting standardized animal models and appropriate behavioral assays is fundamental for both understanding the mechanisms of Parkinson's disease and developing anti-Parkinson drugs.In this paper,we summarize the method of behavioral experiments of Parkinson's disease using mice and rats at home and abroad and systematically summarize the experimental equipment,experimental method,evaluation indexes,and precautions of commonly used Parkinson's behavioral experiments.We also provide an overview of the commonly used animal models of Parkinson's disease and analyze their modeling mechanisms,alignment with the clinical features of Parkinson's disease,and respective advantages and disadvantages.This analysis will help researchers in choosing appropriate animal models of Parkinson's disease and behavioral testing method according to the purpose of the study.

Nicotine addiction is a concern worldwide. Most mechanistic investigations are on nicotine substance dependence properties based on its pharmacological effects. However, no effective therapeutic treatment has been established. Nicotine addiction is reinforced by environments or habits. We demonstrate the neurobiological basis of the behavioural aspect of nicotine addiction. We utilized the conditioned place preference to establish nicotine-associated behavioural preferences (NABP) in rats. Brain-wide neuroimaging analysis revealed that the medial prefrontal cortex (mPFC) was activated and contributed to NABP. Chemogenetic manipulation of µ-opioid receptor positive (MOR⁺) neurons in the mPFC or the excitatory outflow to the nucleus accumbens shell (NAcShell) modulated the NABP. Electrophysiological recording confirmed that the MOR⁺ neurons directly regulate the mPFC-NAcShell circuit via GABA_A receptors. Thus, the MOR⁺ neurons in the mPFC modulate the formation of behavioural aspects of nicotine addiction via direct excitatory innervation to the NAcShell, which may provide new insight for the development of effective therapeutic strategies.

Primary hepatic carcinoma, hepatic carcinoma for short, is a common gastrointestinal tumor with an insidious onset and rapid progression, and its incidence rate is increasing year by year, seriously threatening the life and health of our people. At present, there is still a lack of specific markers for early diagnosis and treatment of hepatic carcinoma, so the research on its biological characteristics and pathogenesis has become very urgent. Metabolic reprogramming is one of the main characteristics of tumor cells, and lipid metabolic reprogramming is involved in the occurrence and development of hepatic carcinoma. Therefore, the key metabolic enzymes and regulatory molecules in the process of lipid metabolism are considered as important targets for the diagnosis and treatment of hepatic carcinoma. This paper mainly focuses on the signaling pathways and regulatory molecules related to hepatocellular carcinoma lipid metabolism, as well as the related anti-hepatoma drugs, so as to provide new ideas for the prevention and treatment of hepatic carcinoma.
