RESUMEN

<p><b>OBJECTIVE</b>To explore susceptibility genes associated with yang-deficiency constitution using single nucleotide polymorphism (SNP) genotyping.</p><p><b>METHODS</b>Based on an epidemiological survey, 30 volunteers with yang-deficiency constitution and 30 volunteers with a balanced constitution were included according to the Classification and Determination Standards of Constitutions in Traditional Chinese Medicine. Peripheral blood was collected and DNA was extracted from white blood cells. A genome-wide association study (GWAS) was conducted by SNP 6.0 genotyping at the Beijing CapitalBio Corporation Ltd. A minimum association P-value (Fisher's exact value) of less than 10(-4) in the allele, genotype, dominant, and recessive models served as the standard for significant association of SNP with yang-deficiency constitution.</p><p><b>RESULTS</b>Among the four genetic models, a total of 42 SNPs were significantly associated with yang-deficiency constitution (Fisher's exact P-values P<10(-4)). These SNPs were adjacent to more than 20 genes, including RGS6, mGluR5, GAPDHL19, and IKZF1.</p><p><b>CONCLUSION</b>Yang-deficiency constitution exhibits the characteristics of polygenic inheritance. This pilot study suggests that the polymorphisms in RGS6, mGluR5, GAPDHL19, and IKZF1 are associated with changes in cyclic adenosine monophosphate and cyclic guanosine monophosphate levels, memory, metabolic energy status, and immune function, respectively in people with yang-deficiency constitution.</p>

RESUMEN

<p><b>OBJECTIVE</b>To explore the relationship between yin-deficiency constitution (YDC) and biochemical indexes by way of observing the endocrinal and immune functions in subjects with YDC.</p><p><b>METHODS</b>On the basis of epidemiological investigation, 60 subjects with YDC and 50 with gentle constitution (GC) were selected according to the pertinent criteria. From each subject, 8 mL of fasting venous blood was drawn at 8:00-9:00 in the morning, with the serum separated by centrifugation 3 000 r/min for 5 min and preserved at -70 degrees Celsius in a freezer. Serum levels of corticosterone, cortisol, adrenocorticotrophic hormone (ACTH), cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), free triiodothyronine (FT3), free thyroxine (FT4), throtropic stimulation hormone, interleukin 1beta (IL-1beta) and interleukin 2 (IL-2) were detected by double-antibody sandwich ELISA; cAMP/cGMP ratio was calculated, and the difference between the two constitutions in terms of these indexes was analyzed.</p><p><b>RESULTS</b>Serum FT3 was 4.16 + or - 1.38 pmol/L in subjects with YDC, which was higher than that in subjects with GC (3.71 + or - 0.55 pmol/L), but levels of cortisol (124.58 + or - 45.36 ng/mL), ACTH (58.92 + or - 14.55 pg/mL), cGMP (66.00 + or - 18.02 pmol/mL) and FT4 (12.33 + or - 3.12 pmol/L) in YDC were lower than those in GC (13.43 + or - 2.31 pmol/L), showing significant difference (P<0.05).</p><p><b>CONCLUSION</b>YDC is related to some extent with the disturbances in the hypothalamus-pituitary-adrenal axis, hypothalamus-pituitary-thyroid axis, cyclic nucleoside system and immune function.</p>
