Objective: To study the etiology, epidemiology, clinical and pathological features, diagnose and treatment of cat-scratch disease(CSD).
Method: The clinical information of 1 case was reported and the literatures were also reviewed.
Result: Bartonella henselae was the primary pathogen of CSD. Almost all patients with CSD were in contact with animals, especially cat or dog before the occurrence of the disease. All the patients had the self-limited swelling of local lymph nodes and commonly a fever. The pathological feature was necrotic granulation-like micro abscessation, and a pleomorphous argyrophil G- bacillus could be showed by Warthin-Starry or Brown-Hopp stainings in the swelling lymph nodes.
Conclusion: CSD is a self-limited bacterial infectious disease. And its clinical features,biopsy and special stainings of swelling lymph nodes are helpful to the final diagnosis. Gentamicin, rifadin, ciprofloxacin, clarithromycin, bactrim, mitramycin, or resection of swelling lymph nodes had good effects on treating CSD.

The current understanding of humoral immune response in cancer patients suggests that tumors may be infiltrated with diffuse B cells of extra-tumoral origin or may develop organized lymphoid structures, where somatic hypermutation and antigen-driven selection occur locally. These processes are believed to be significantly influenced by the tumor microenvironment through secretory factors and biased cell-cell interactions. To explore the manifestation of this influence, we used deep unbiased immunoglobulin profiling and systematically characterized the relationships between B cells in circulation, draining lymph nodes (draining LNs), and tumors in 14 patients with three human cancers.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the standard method for sampling mediastinal/hilar lymph node disease. However, the smaller samples obtained via needle aspiration have a lower diagnostic rate for benign compared to malignant diseases. The low diagnostic rates have been reported to be improved through using endobronchial ultrasound-guided intranodal forceps biopsy (EBUS-IFB), but the implementation of IFB presents technical challenges, as described with variable results in certain studies.

Background: Orthotopic murine models of pancreatic cancer represent an important tool for evaluating treatment strategies. Several genetically modified mouse tumors and xenograft models have been reported. Genetic models have unpredictable growth and variable waiting period, while orthotopic models are operative ones, difficult to create and result in irregular metastasis.

Background: There is a clear correlation between accurate postoperative lymph node staging and the survival prognosis of patients. This study aimed to explore the application and value of indocyanine green (ICG) fluorescence real-time imaging technology in lymph node sorting during radical esophagectomy for esophageal cancer.
Methods: From August 2022 to June 2023, the specimens of 66 patients who underwent esophageal cancer resection with lymph node dissection were examined.

Chest computed tomography (CT) is the most frequently performed imaging examination worldwide. Compared with chest radiography, chest CT greatly improves the detection rate and diagnostic accuracy of chest lesions because of the absence of overlapping structures and is the best imaging technique for the observation of chest lesions. However, there are still frequently missed diagnoses during the interpretation process, especially in certain areas or "blind spots", which may possibly be overlooked by radiologists.
