Abstract:
The "exterior-interior relationship between lung and large intestine" is one of the theories of traditional Chinese medicine, which is scientific in modern medicine. The ancients discovered the specific connection between the lung and large intestine, and constructed the theory of "exterior-interior relationship between lung and large intestine" through the Yin-Yang theory and the meridian attachment. The theory of "exterior-interior relationship between lung and large intestine" has been of great significance in the critical care field since the first study on intestinal tract and acute respiratory distress syndrome (ARDS) was carried out in the emergency medicine in 1980s. This article analyzes the consistence of lung and large intestine in early embryonic development, explains the close connection between the lung and large intestine through the intestinal flora translocation theory in sepsis, and reviews the immunoregulation mechanism of helper T cell 17 (Th17) in intestine and lung, and the possible molecular mechanism of immune response, so as to provide physicians with further exploration of the traditional theory of "exterior-interior relationship between lung and the large intestine".

01:25Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection....
01:09Large Intestine
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
