Due to different disease background of gastric stump cancer(GSC) patients (benign or malignant lesion, reconstruction of digestive tract, etc.), the GSC surgical procedure and the difficulty of lymphadenectomy are also different. The extent of radical lymphadenectomy for gastric stump cancer should extend beyond D2 lymphadenectomy, according to the different backgrounds of initial disease, reconstructions, and tumor location. A lymphadenectomy should include the lymph nodes in anterior (No.17) and posterior (No...

BACKGROUND: It is unclear how preoperative therapy for gastric cancer affects the metastasis rate of lymph nodes (LNs) and whether the location of positive LNs affects survival after preoperative therapy. Therefore, we determined the association between positive central lymph nodes (CnLNs) and disease stage and overall survival (OS). METHODS: We reviewed a prospectively maintained database to identify patients who had undergone resection of gastric adenocarcinoma at our institution from 2005 to 2015...

Fever of unknown origin (FUO) refers to fevers of > 101 °F that persist for > 3 weeks and remain undiagnosed after a focused inpatient or outpatient workup. FUO may be due to infectious, malignant/neoplastic, rheumatic/inflammatory, or miscellaneous disorders. The FUO category determines the focus of the diagnostic workup. In the case presented of an FUO in a young woman, there were clinical findings of both CMV infectious mononucleosis or a lymphoma, e.g., highly elevated ESR, elevated ferritin levels, and elevated ACE level, β-2 microglobulins...

The average age of the human population is rising leading to an increasing burden of age-related diseases, including increased susceptibility to infection. However, immune function can decrease with age which could impact on processes that require a functional immune system. Aging is also characterised by chronic low-grade inflammation which could further impact immune cell function. Whilst changes to neutrophils in blood during aging have been described, little is known in aging lymphoid organs. This study used female C57 BL /6J mice comparing bone marrow ( BM ), spleen and lymph nodes from young mice aged 2-3 months (equivalent to 18 human years) with healthy elderly mice aged 22-24 months (equivalent to 60-70 human years)...

Colorectal cancer, a malignant tumor arising from the colon or rectum, is a common cancer in China, with most patients diagnosed at the advanced stage or locally advanced stage. Large tumor size results in the invasion of adjacent organs and the multiple organ involvement, which poses certain challenges for clinical treatment. When facing advanced stage colorectal cancer, some surgeons do not consider surgery, a reasonable option. However, in fact, multi-disciplinary treatment can achieve relatively good treatment outcomes in patients with advanced stage or locally advanced stage colorectal cancer...

In the past there have been a multitude of studies that ardently support the role of Arginase II (Arg II) in vascular and endothelial disorders however, the regulation and function of Arg II in autoimmune diseases has thus far remained unclear. Here we report that a global Arg II null mutation in mice suppressed experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. During EAE both Arg I and Arg II were induced in spinal cords, but only Arg II was induced in spleens and splenic DCs...

Angioimmunoblastic T cell lymphoma (AITL) is a peripheral T cell non-Hodgkin lymphoma with an aggressive fatal course and it has varied clinical presentation with an uncommon presentation when they present as soft tissue masses or when there is spill in the peripheral blood or there are composite lymphomas that are rare presentations. Common presentations include lymphadenopathy, fever and systemic symptoms, hemolytic anemias, skin rashes, and rheumatoid arthritis. The classical histopathology is absence of follicles in lymph nodes with presence of high endothelial venules and the tumor cells of small to medium-sized lymphocytes with pale cytoplasm mixed with reactive T cells...

BACKGROUND: Ulcerative colitis (UC) is a type of inflammatory bowel disease (IBD) characterized by chronic inflammation of colon. It is commonly believed that the imbalance of immune system and overwhelming production of cytokines are involved in the pathogenesis of UC. Recent studies demonstrated that interleukin-35 (IL-35), a key player in the regulation of inflammation, has been identified as potential therapeutic target to treat UC. However, conventional intravenous administration is costly and inconvenient...

B cells play a major role in the adaptive immune response by producing antigen-specific antibodies against pathogens and imparting immunological memory. Following infection or vaccination, antibody-secreting B cells and memory B cells are generated in specialized regions of lymph nodes and spleens, called germinal centers. Here, we report a fully synthetic ex-vivo system that recapitulates the generation of antigen-specific germinal-center (GC) like B cells using material-surface driven polyvalent signaling...

In recent years, the incidence of gastric cancer has shown a decreasing trend. However, the incidence of advanced upper gastric cancer in China is steadily increasing. Nowadays, surgery is the only way to cure advanced gastric cancer, and lymph node dissection is the key of operation. Since lymph node metastasis is the main metastatic route of gastric cancer, it is critical for surgeons to be aware of this when performing lymph node dissection during operation. At present, the only possible cure for advanced gastric cancer is surgery...

According to Japanese gastric cancer treatment guidelines, the standard operation for locally advanced upper third gastric cancer is the total gastrectomy with D2 lymphadenectomy, which includes the dissection of the splenic hilar lymph nodes. With the development of minimally invasive ideas and surgical techniques, laparoscopic spleen-preserving splenic hilar lymph node dissection is gradually accepted. It needs high technical requirements and should be carried out by surgeons with rich experience of open operation and skilled laparoscopic techniques...
