In thoracoscopic pulmonary nodule resection surgery, precise preoperative planning is crucial. Artificial intelligence (AI)-assisted three-dimensional (3D) reconstruction technologies have shown great potential in this area. AI-assisted 3D reconstruction technologies can provide accurate, personalized models of the pulmonary vasculature and bronchial anatomy, assisting surgeons in detailed surgical planning and thus enhancing the precision and safety of surgeries. This article reviews the application progress of AI-assisted 3D reconstruction technologies in pulmonary nodule surgery, including their applications in preoperative diagnosis, surgical planning, and intraoperative navigation, as well as the advancements in AI-assisted 3D reconstruction technologies. It analyzes the technical features of all kinds of 3D reconstruction methods, their clinical applications, and the challenges they face.

Pancreaticobiliary maljunction （PBM） is a rare congenital developmental defect of the biliary-pancreatic system characterized by a junction of the pancreatic and bile ducts outside the duodenal wall， forming an extended common channel. This anatomical anomaly compromises the normal function of Oddi’s sphincter， weakens defenses against reflux， and thus triggers a series of biliary and pancreatic complications. Although there is a relatively low incidence rate of PBM， its insidious clinical symptoms often lead to delayed diagnosis， which increases the difficulties in treatment and the risk of poor prognosis. For PBM patients with marked bile duct dilatation， surgical intervention， especially cholecystectomy combined with extrahepatic bile duct resection and bile duct-jejunum Roux-en-Y anastomosis， remains the standard treatment at present. For PBM without marked bile duct dilatation， there are still controversies over related treatment strategies， and most experts are in favor of cholecystectomy， while there is still a lack of consensus on the management of extrahepatic bile ducts， which requires further research and exploration. Endoscopic retrograde cholangiopancreatography （ERCP） is currently the gold standard for diagnosing PBM and assessing pancreaticobiliary abnormalities， and it can not only clarify the nature of lesion， but also collect the bile and biliary duct tissue for pathological examination. ERCP also has the function of interventional treatment， such as stenting， expansion， and drainage， thereby bringing benefits to patients comorbid with biliary neoplasms. However， the application of ERCP in screening is limited by its invasiveness， with increases in technique complexity and the risk of complications in the pediatric population. This article summarizes the definition， classification， pathogenesis， and epidemiological features of PBM and the research advances in current diagnosis and treatment strategies， in order to provide guidance for clinical practice.

Tracheobronchial adenoid cystic carcinoma （TACC） is a low-grade malignant tumor originating from the airway mucosa. Despite its slow progression，it is characterized by high invasiveness，frequent recurrence，and a strong tendency for metastasis. Preclinical studies have shown that vascular-targeted therapy holds significant potential. However，an effective systemic treatment for TACC has not been established yet. This study explored TACC from the perspective of "Feiji" in traditional Chinese medicine （TCM） as the starting point. It deeply investigated the mechanisms of abnormal collaterals and tumor vascular recruitment and further elaborated on the theoretical connection between abnormal collaterals and tumor vascular recruitment. Firstly，collateral hyperactivity led to disordered and erratic pulmonary collaterals. Their abnormal structures were similar to the disorderly and tortuous nature of tumor （pseudo）angiogenesis. This resulted in imbalances in the functions of circulation，perfusion，and reverse injection of the pulmonary collaterals，and then led to unrestrained collateral dysfunction and the accumulation of pathogenic factors. Secondly，the remodeling of the extracellular matrix （ECM） and epithelial-mesenchymal transition （EMT） in TACC were critical processes in vascular co-option （VCO），representing the micro-level manifestation of the displacement of nutrient and defense. During this process，ECM remodeling made TACC cells more likely to hijack normal blood vessels，creating a complex vascular microenvironment conducive to tumor growth. In terms of treatment，this study proposed a TCM strategy of "regulating collaterals to expel pathogenic factors and nourishing collaterals to strengthen the healthy Qi"，and listed potential TCM. These were intended to regulate the Qi and blood in the collaterals，repair the functions of abnormal collaterals，and intervene in the vascular recruitment process of TACC. Future research should focus on improving the TCM clinical syndrome characteristics of TACC. Through modern molecular biology techniques，it is necessary to deeply analyze the micro-level pattern of vascular recruitment in TACC. This would enrich the understanding of the profound connection between abnormal collaterals and tumor vascular recruitment，providing empirical evidence for TCM-targeted therapies for vascular recruitment in TACC.

Acute lung injury （ALI） is one of the most common and critical diseases in clinical practice， with extremely high morbidity and mortality， seriously threatening human life and health. The pathogenesis of ALI is complex， in which the inflammatory response is a key factor. Studies have shown that NOD-like receptor protein 3 （NLRP3） inflammasomes are involved in ALI through mechanisms such as inflammation induction， increased microvascular permeability， recruitment of neutrophils， oxidative stress， and pyroptosis， playing a key role in the occurrence and progression of ALI. Therefore， regulating NLRP3 inflammasomes and inhibiting the release of inflammatory factors can alleviate the damage in ALI. At present， ALI is mainly treated by mechanical ventilation and oxygen therapy， which have problems such as high costs and poor prognosis. In recent years， studies have shown that traditional Chinese medicine （TCM） can reduce the inflammatory response and the occurrence of oxidative stress and pyroptosis by regulating the NLRP3 inflammasome， thus alleviating the damage and decreasing the mortality of ALI. Based on the relevant literature in recent years， this article reviews the research progress in TCM treatment of ALI by regulating NLRP3 inflammasomes， discusses how NLRP3 inflammasomes participate in ALI， and summarizes the active ingredients， extracts， and compound prescriptions of TCM that regulate NLRP3 inflammasomes， aiming to provide new ideas for the clinical treatment of ALI and the development of relevant drugs.

ObjectiveTo explore the effect of respiratory training based on core stabilization training on lumbar disc herniation. MethodsFrom January, 2023 to October, 2024, 96 patients with lumbar disc herniation admitted to the First Affiliated Hospital of Bengbu Medical University were divided into control group (n = 32), core group (n = 32) and respiratory group (n = 32). All the groups underwent conventional rehabilitation therapy, with core stabilization training in the core group and respiratory training combined with core stabilization training in the respiratory group, additionally, for four weeks. Before and after training, the scores of Visual Analogue Scale, Japanese Orthopaedic Association (JOA) and Oswestry Dysfunction Index (ODI) were compared, the average electromyographic value (AEMG) and root mean square (RMS) value of the multifidus and transversus abdominis were detected by surface electromyography (sEMG); and the thickness of the multifidus and transversus abdominis were measured by musculoskeletal ultrasonography bilaterally. ResultsThe intra-group effect (F > 597.796, P < 0.001), inter-group effect (F > 16.535, P < 0.001) and interaction effect (F > 49.622, P < 0.001) were significant in the scores of VAS, JOA and ODI; which were better in the respiratory group than in the control group and the core group (P < 0.05), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 7971.631, P < 0.001), inter-group effect (F > 177.760, P < 0.001) and interaction effect (F > 478.771, P < 0.001) were significant in the thickness of the transversus abdominis and multifidus; which were better in the respiratory group than in the control group and the core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 144303.007, P < 0.001), inter-group effect (F > 1495.458, P < 0.001) and interaction effect (F > 3121.361, P < 0.001) were significant in the RMS of the multifidus and transversus abdominis; which were better in the respiratory group than in the control group and the core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 1890.532, P < 0.001), inter-group effect (F > 607.132, P < 0.001) and interaction effect (F > 824.923, P < 0.001) were significant in the AEMG of the multifidus and transversus abdominis; which were better in the respiratory group than in the control group and core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). ConclusionCore training combined with respiratory training can more effectively reduce pain and improve dysfunction by enhancing the strength and control of the core muscles， thus improving the quality of life of patients with lumbar disc herniation.

The integration of UPLC-Q-Orbitrap-MS， MDF and GNPS can provide a reference for the rapid qualitative analysis of other Chinese medicines.

BackgroundPatients with depressive disorder often exhibit impaired decision-making functions. However， the relationship between decision-making abilities and depressive and anxiety symptoms in these patients remains unclear. ObjectiveTo explore the characteristics of decision-making behavior in patients with depressive disorder， and to analyze its relationship with clinical symptoms. MethodsA total of 48 patients diagnosed with depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） were recruited from the Department of Psychosomatic Medicine of the Affiliated Hospital of Southwest Medical University from October 2020 to May 2023. Concurrently， 52 healthy individuals matched for age and gender were recruited from Luzhou as the control group. Beck Depression Inventory （BDI） and Beck Anxiety Inventory （BAI） were used for assessment， and decision-making behavior was evaluated using Probabilistic Reversal Learning （PRL） task. Indicators assessed included the number of trials to criterion， perseverative errors， win-stay rate and lose-shift rate. Spearman correlation analysis was used to assess the correlation between BDI and BAI scores and PRL task indicators. ResultsThe depression group showed a significantly higher lose-shift rate compared with the control group （t=3.684， P<0.01）. There were no statistically significant differences between two groups in trials to criterion， perseverative errors and win-stay rate （t=0.329， 0.132， 0.609， P>0.05）. In depression group， BDI and BAI scores were positively correlated with the win-stay rate（r=0.450， 0.398， P<0.01）. ConclusionPatients with depressive disorder are more likely to change their decision-making strategies following negative outcomes. Furthermore， the severity of depressive and anxiety symptoms is associated with a greater propensity to maintain existing decisions after receiving positive feedback. ［Funded by 2019 Joint Project of Luzhou Science and Technology Bureau-Southwest Medical University （number， 2019LZXNYDJ39］

Objective To explore the infection status and clinical characteristics of human parvovirus B19 (HPV-B19) in patients with hematological disease. Methods A total of 94 patients with benign hematological disease, 128 patients with hematological malignancy, and 89 healthy individuals at Shanghai Eighth People’s Hospital from February 2019 to February 2020 were selected. The levels of specific IgM and nucleic acid of HPV-B19 in the plasma were detected using ELISA and PCR. The infection rates among the 3 groups and clinical characteristics between HPV-B19 positive and negative patients with hematological disease were compared. Results The positive rate of HPV-B19 IgM was 9.6% (9/94), the positive rate of nucleic acid was 11.7% (11/94), and the overall infection rate of HPV-B19 (IgM and/or nucleic acid positive) was 14.9% (14/94) in benign group of patients. The positive rate of HPV-B19 IgM was 18.0% (23/128), the positive rate of nucleic acid was 19.5% (25/128), and the overall infection rate of HPV-B19 was 26.6% (34/128) in malignant group of patients. The positive rate of HPV-B19 IgM was 1.1% (1/89), the positive rate of nucleic acid was 2.2% (2/89), and the overall infection rate of HPV-B19 was 2.2% (2/89) in healthy controls. The overall HPV-B19 infection rate in benign group of patients was higher than that in healthy controls (P＝0.006). The overall HPV-B19 infection rate was higher in malignant group of patients than that in benign group of patients (P＝0.037) and healthy controls (P＜0.001). In the benign group, the HPV-B19 infection rates in patients with pure red cell aplasia (PRCA), autoimmune hemolytic anemia (AIHA), immune thrombocytopenic purpura (ITP), and aplastic anemia (AA) were higher, with 44.4% (4/9), 27.3% (3/11), 25.0% (4/16), and 21.4% (3/14), respectively. In the malignant group, the HPV-B19 infection rates in patients with non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL) were higher, with 42.9% (9/21) and 37.5% (6/16), respectively. The HPV-B19 positive patients in both hematological disease groups were older (P＜0.05). In patients with NHL, CLL or multiple myeloma (MM), HPV-B19 infection decreased the reticulocyte ratio (P＜0.05); in patients with NHL, acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL), HPV-B19 infection prolonged bone marrow suppression time after chemotherapy (P＜0.05). Conclusions HPV-B19 infection rate in patients with hematological disease is elevated and HPV-B19 infection may influence the condition and treatment efficiency of these patients.
