Liver Qi deficiency is also known as Liver Qi deficiency. Liver Qi is the material basis and driving force for the liver to carry out its physiological functions. When Liver Qi is insufficient, the various functions of the liver are seen to diminish and Liver Qi deficiency lesions appear. Liver Qi deficiency evidence commonly exists. Common tests 1. Echinocytic erythrocytes Erythrocytes have pinpoint protrusions on their surface, which are irregularly spaced. The length and width of the protrusions vary. They are more frequent in blood smears of patients with beta lipoprotein deficiency. They are also seen after splenectomy and in alcoholic liver disease. Note the distinction from crinkled erythrocytes. Crinkled red blood cells are closely arranged with serrated periphery, equal in size, and more pointed at the outer end. 2, A fetal globulin test AFP is a single peptide chain glycoprotein composed of 590 amino acids, which is an embryonic protein, mainly produced by the hepatocytes and yolk sac during the embryonic period, and a small amount can also be produced by the mucosal epithelium of the gastrointestinal tract. The concentration of AFP decreases rapidly after birth and approaches adult levels within a few months to a year. Its amino acid sequence has great homology with human serum albumin, and the genes for both are located on the same DNA strand. Normal liver cells do not produce AFP, but synthesize albumin. Urinary testosterone Testosterone is the main androgen in human body. 95% of plasma testosterone in adult men comes from testicular interstitial cells, and a small portion comes from adrenal cortex and extra-glandular transformation. In women, it mainly comes from the adrenal cortex, with a small amount secreted by the ovaries. Testosterone is the main indicator of androgen. 4, inter alpha trypsin inhibitor Once called protein π, is a single polypeptide chain composed of glycoprotein, unstable in nature, leukocyte elastase can be cleaved into two nodal pieces, one of which can inhibit trypsin, chymotrypsin and other proteases. Electrophoresis is located in the alpha 2 globulin region. 5, cerebrospinal fluid glutamine The free ammonia produced by the process of amino acid metabolism in brain tissue can be synthesized by the action of glutamine synthetase to eliminate the toxic effects of ammonia on the central nervous system. Ammonia in cerebrospinal fluid is about 1/3 of that in arterial blood. 6. Immunoelectrophoresis A qualitative method combining agar electrophoresis and bidirectional agar diffusion for the analysis of antigen composition. It was created by GrABar and Williams in 1953. This technique is a basic immunological technique widely used in biomedical fields because of the high specificity of the antigen-antibody reaction and the rapidity, sensitivity and high resolution of the electrophoretic separation technique.
