Objective The purpose of this study was to provide practical anatomic data for the imaging diagnosis and surgical treatment of the disease of the subphrenic spaces. Methods Sectional anatomy of the subphrenic spaces on the coronal plane were investigated on 30 sets of serial coronal sections of superior abdomen of Chinese adult cadavers and MR imaging of 2 abdomen of cadavers. Results Subphrenic spaces were divided into perihepatic spaces and perisplenic spaces on the coronal plane.The space between the anterior margin of left gastropancreatic fold and the posterior layer of hepatogastric ligament is the only direct communication between the superior and inferior recesses of the lesser sac.Its communicating type is divided into three types on the coronal plane.The right layer of the gastrophrenic ligament is continuous with the posterior layer of the lesser omentum,the left layer of the gastrophrenic ligament is continuous with the right layer of the phrenicosplenic ligament and the posterior layer of the gastrosplenic ligament.Left gastropancreatic fold is continued to the left and right layers of gastrophrenic ligament upward.The bare area of stomach is located between the left and right layers of gastrophrenic ligament,its existing rate is 100%.The bare area of spleen is located among phrenicosplenic ligament,gastrosplenic ligament,splenorenal ligament and splenocoloic ligament.Its the most width exists at the splenorenal ligament.It is divided into the part of the splenic hilus and the splenorenal part.Its maximum is 2 64?1 16 cm,4 16?2 24 cm respectively. Conclusion The coronal plane is dominant for showing left gastropancreatic fold and the communication relationship between superior and inferior recesses of the lesser sac.The superior and inferior recesses of the lesser sac that may communicate with each other is 73 3 percent of all the cases studied

Objective:To investigate the changes of non-specific and HBV core antigen (HBcAg)-specific Th9 cells, and intereleukin-9 (IL-9) in HBV-infected patients, and to assess the influence of Th9 cells on CD8 + T cell function. Methods:Twelve patients with acute hepatitis B (AHB) and 58 with chronic hepatitis B (CHB), who were hospitalized in the First Affiliated Hospital of Xinxiang Medical University between January 2018 and January 2019, were enrolled in this study. Twenty healthy subjects negative for HBsAg were selected as controls. Peripheral blood mononuclear cells (PBMCs) and plasma samples were isolated. Non-specific Th9 cells (CD3 + CD4 + IL-9 + ) and HBcAg-specific Th9 cells were analyzed by flow cytometry. Plasma IL-9 level was measured by enzyme linked immunosorbent assay. CHB patients received tenofovir disoproxil fumarate (TDF) antiviral therapy. The changes of non-specific Th9 cells, HBcAg-specific Th9 cells and plasma IL-9 level were assessed 48 weeks after TDF therapy. CD4 + CCR4 -CCR6 -CXCR3 -(Th9) cells and CD8 + T cells were isolated from 12 HLA-A2 restricted CHB patients and co-cultured with HepG2.2.15 cells with the presence of anti-IL-9 neutralizing antibody. The percentage of dead HepG2.2.15 cells and the levels of IFN-γ and TNF-α were detected. Student′s t test, one-way analysis of variance or SNK- q test was used for statistical comparison between groups. Results:There were no significant differences in non-specific Th9 cells or plasma IL-9 level among AHB patients, CHB patients and healthy controls ( P>0.05). HBcAg-specific Th9 cells was down-regulated in CHB patients when compared with AHB patients [(2.49±0.61)% vs (3.19±0.62)%, P<0.001]. The percentage of HBcAg-specific Th9 cells was negatively correlated with HBV DNA ( r=-0.385, P=0.003), but not correlated with ALT ( P>0.05) in CHB patients. TDF therapy for 48 weeks remarkably elevated the HBcAg-specific Th9 cells [(2.94±0.48)%, P<0.001], however, did not affect non-specific Th9 cells or plasma IL-9 level ( P>0.05) in CHB patients. The cytotoxicity of HBcAg-specific Th9 cells was low in CHB patients. However, HBcAg-specific Th9 cells could induce enhanced cytotoxicity of CD8 + T cells to HepG2.2.15 cells, which manifested as increased percentage of dead HepG2.2.15 cells and higher levels of IFN-γ and TNF-α. Anti-IL-9 neutralizing antibody reduced the enhancement of CD8 + T cell cytotoxicity by HBcAg-specific Th9 cells ( P<0.001). Conclusions:Chronic HBV infection might suppress the level and function of HBcAg-specific Th9 cells, resulting in persistent infection.
