Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity， and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity， this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine （TCM） herbs that strengthen the spleen， regulate qi， and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation， promoting water-damp metabolism， and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness， internal accumulation of phlegm dampness" and immune dysregulation in obesity， this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

Objective To investigate the value of CT in diagnosis of acuteppendicitis. Methods Acute appendicitis was confirmed by pathology in 30 cases after the operation. CT features of 30 acute appendicitis were analyzed and compared with the surgery and pathological results retrospectively. Results Among of 30 acute appendicitis,20 cases were simple appendicitis,6 cases were acute suppurative appendicitis and 4 cases were appendiceal abscess. 20 cases simple appendicitis showed the appendix enlarged in diameter,with wall thickening in CT imaging. 6 cases acute suppurative appendicitis showed the appendix enlarged in diameter,with wall thickening and periappendiceal inflammation in CT imaging. 4 cases appendiceal abscess showed inflammatory tumors with asymmetrical attenuation in ileocecal region and complicating fluid collection in right iliac fossa and cavity of pelvis in CT imaging. In 4 cases appendiceal abscess,2 cases complicated small intestine obstruction. 7 cases appendiceal fecalith were found in 30 acute appendicitis. Conclusion CT scanning can illustrate feature of acute appendicitis and make correct diagnosis,and can provide important information for clinician.
