Right middle pulmonary vein classification by 3D-CT reconstruction and its clinical significance.

Background: A profound understanding of the type of right middle lobe (RML) vein return is crucial for thoracic surgeons to ensure safe anatomic lung resection. In this study, the type of venous return in the RML and its clinical significance were analyzed using the 3D computed tomography (3D-CT) reconstruction technique.

Methods: This retrospective study analyzed the patients who underwent anatomical lobectomy or anatomical lung segment resection with preoperative 3D-CT reconstruction at the Department of Thoracic Oncology Surgery, Fujian Cancer Hospital from January 2020 to October 2022.

Construction and validation of a risk-scoring model to predict lymph node metastasis in T1b-T2 esophageal cancer.

Background: Lymph node status is an important factor in determining preoperative treatment strategies for stage T1b-T2 esophageal cancer (EC). Thus, the aim of this study was to investigate the risk factors for lymph node metastasis (LNM) in T1b-T2 EC and to establish and validate a risk-scoring model to guide the selection of optimal treatment options.

Methods: Patients who underwent upfront surgery for pT1b-T2 EC between January 2016 and December 2022 were analyzed.

A cross-sectional study: analysis of anatomical variation in the right upper lung intersegmental vein V2a based on a 3D reconstruction technique.

Background: This study aimed to summarize and analyze the anatomical structures of the right upper lung intersegmental vein V2a based on 3-dimensional (3D) reconstruction technology.

Methods: We collected the enhanced computed tomography (CT) scans of 157 patients with pulmonary diseases, and reconstructed the right upper lung tissue structure through interactive qualitative and quantitative analysis (IQQA). According to the reconstruction results, the V2a of the right upper pulmonary intersegmental vein was returned to different veins for classification, and the subtypes were further subdivided according to the different vascular routes and the location of the pulmonary segmental bronchus.

Anatomical analysis of variations in the bronchus pattern of the left upper lobe using three-dimensional computed tomography angiography and bronchography.

Background: The number of sublobar resections performed is increasing, thoracic surgeons must be familiar with bronchus anatomy and preoperative planning plays an important role in predicting anatomical variations. However, there is few report showing anatomic variations of the left upper lobe (LUL) using three-dimensional computed tomography angiography and bronchography (3D-CTAB), and no in Chinese population. The present study aimed to use 3D-CTAB to describe variations of the pulmonary bronchus of LUL in Chinese population.

Biodegradable Nanoprobe for NIR-II Fluorescence Image-Guided Surgery and Enhanced Breast Cancer Radiotherapy Efficacy.

Positive resection margin frequently exists in breast-conserving treatment (BCT) of early-stage breast cancer, and insufficient therapeutic efficacy is common during radiotherapy (RT) in advanced breast cancer patients. Moreover, a multimodal nanotherapy platform is urgently required for precision cancer medicine. Therefore, a biodegradable cyclic RGD pentapeptide/hollow virus-like gadolinium (Gd)-based indocyanine green (R&HV-Gd@ICG) nanoprobe is developed to improve fluorescence image-guided surgery and breast cancer RT efficacy.

Surgical Navigation for Malignancies Guided by Near-Infrared-II Fluorescence Imaging.

Near-infrared (NIR) fluorescence imaging is an emerging noninvasive imaging modality, with unique advantages in guiding tumor resection surgery, thanks to its high sensitivity and instantaneity. In the past decade, studies on the conventional NIR window (NIR-I, 750-900 nm) have gradually focused on the second NIR window (NIR-II, 1000-1700 nm). With its reduced light scattering, photon absorption, and auto-fluorescence qualities, NIR-II fluorescence imaging significantly improves penetration depths and signal-to-noise ratios in bio-imaging.

Analysis of anatomical variations of the lingular artery of the left upper lobe using 3D computed tomography angiography and bronchography.

Background: Thoracic surgeons must be familiar with the anatomy of the pulmonary artery during segmentectomy and segmentectomy. But pulmonary arteries have numerous variations and aberrant branching patterns. The purpose of the present study was to analyze the anatomical variations and frequencies of the lingular artery of the left upper lobe (LUL) using 3D computed tomography angiography and bronchography (3D-CTAB).

The role of endoscopic tumor length in resected esophageal squamous cell carcinoma: a retrospective study.

Background: In esophageal squamous cell carcinoma (ESCC), tumor status is assessed on the basis of latitudinal invasion. Endoscopic tumor length (ETL) may represent the longitudinal scope of the primary tumor, and whether it affects tumor stage or prognosis is not entirely clear. In this study, we evaluated the role of ETL in patients with resected ESCC.

[Effects of Tongbi capsule on joint lesions in rabbits with rheumatoid arthritis].

The purpose of this experiment is to observe the effects of Tongbi capsule on joint lesions in rabbit with rheumatoid arthritis induced by ovalbumin and explore the mechanism in order to provide reference for clinical application of Tongbi capsule. Rheumatoid arthritis in rabbits was induced by subcutaneous injection of emulsions of ovalbumin and Freund's complete adjuvant and intra articular injection of ovalbumin. After successful modeling, 30 New Zealand rabbits with arthritis were randomly divided into model control group, the high, medium and low dose groups of Tongbi capsule (90, 45, 22.

Curcumin supplementation ameliorated vascular dysfunction and improved antioxidant status in rats fed a high-sucrose, high-fat diet.

Vascular endothelial dysfunction is a potential risk factor for cardiovascular disease. This study evaluated the effect of curcumin on factors associated with vascular dysfunction using rats fed a high-sucrose, high-fat (HSF) diet. The experiment included 2 animal feeding phases.

Alpha-mangostin from mangosteen ( pericarp extract reduces high fat-diet induced hepatic steatosis in rats by regulating mitochondria function and apoptosis.

Background: Non-alcoholic fatty liver disease (NAFLD) is caused by multiple factors including hepatic oxidative stress, lipotoxicity, and mitochondrial dysfunction. Obesity is among the risk factors for NAFLD alongside type 2 diabetes mellitus and hyperlipidemia. α- mangostin (α-MG) extracts from the pericarps of mangosteen ( may regulate high fat diet-induced hepatic steatosis; however the underlying mechanisms remain unknown.

Fitz-Hugh-Curtis syndrome: clinical diagnostic value of dynamic enhanced MSCT.

[Purpose] This study aimed to investigate the clinical diagnostic value of dynamic enhanced multislice computed tomography (MSCT) for Fitz-Hugh-Curtis syndrome (FHCS). [Subjects and Methods] This study retrospectively analyzed the clinical features and manifestations of scanning and dynamic enhanced MSCT in 19 patients with FHCS. [Results] MSCT scans showed different degrees of liver capsule thickness in the lesion area: seven cases of sub-capsular effusion and three cases with a small amount of pleural effusion; thickness of the liver capsular arterial phase showing significant enhancement in 17 cases, and slight enhancement in two; portal venous and delayed phase enhancement decreased with no clear boundary of the liver parenchyma; and adjacent hepatic parenchymal involvement in five cases, in which the arterial phase appeared to have patchy or triangular enhancement, and unclear portal vein and delayed phase imaging findings.

[Protective effect of pueraria flavonoid on the cerebral ischemic reperfusion injury in rats].

Objective: To research the protective effect of pueraria flavonoid on the cerebral ischemic reperfusion injury.

Method: Using the middle cerebral artery occlusion model (MCAO) in rats, we investigated the influence of pueraria flavonoid on the brain water content, the infarct volume, the activities of SOD, and the content of MDA.
