RESUMO
<p><b>OBJECTIVE</b>To study the expression level and role of apoptosis-associated speck-like protein containing a caspase recruitment domain (PYCARD) gene transcript variant mRNA in peripheral blood mononuclear cells (PBMCs) of primary gout (PG) patients with different Chinese medicine (CM) syndromes.</p><p><b>METHODS</b>The expressions of PYCARD gene transcript variant mRNA and interleukin-1β (IL-1β) mRNA in PBMCs were investigated in 96 PG patients with acute phase (APPG, 44 cases) and non-acute phase (NAPPG, 52 cases) and 30 healthy controls (HCs) by reverse transcription-polymerase chain reaction (PCR) and/or realtime quantitative PCR. PYCARD and nuclear factor-κB (p50) [NF-κB (p50)] protein was detected by Western blot in PBMCs respectively. IL-1β, IL-4 and IL-10 protein levels in plasma of HCs and PG patients were measured by enzyme-linked immuno sorbent assay.</p><p><b>RESULTS</b>The main CM syndromes in APPG patients were obstruction of dampness and heat syndrome (ODHS, 36.36%) and intermingled phlegm-blood stasis syndrome (IPBSS, 27.27%), while in NAPPG patients were Pi (Spleen)-deficiency induced dampness syndrome (PDIDS, 40.38%) and qi-blood deficiency syndrome (QBDS, 26.92%). It showed statistical significances of the expressions of PYCARD gene and its transcript variant mRNA, the protein of PYCARD and NF-κB (p50) and the plasma IL-1β, IL-4 and IL-10 in APPG, NAPPG, ODHS, IPBSS, PDIDS and QBDS groups, compared with the HC group respectively (P<0.05 or P<0.01). There were also significant differences of mRNA expressions of PYCARD-1 and PYCARD-2 as well as protein expressions of IL-1β, IL-4 and IL-10 among the 4 CM syndromes groups (P<0.05 or P<0.01). Correlation analysis showed positive correlation between the mRNA expressions of PYCARD-1 gene transcript variant and IL-1β in APPG patients (r=0.3088, P=0.0183).</p><p><b>CONCLUSION</b>PYCARD gene and its transcript variant may play a critical and regulative role in the inflflammatory response of PG patients with different phases and CM syndromes.</p>
RESUMO
<p><b>OBJECTIVE</b>To understand the difference in clinical indicators of gout patients of different Chinese medical syndromes and its clinical significance.</p><p><b>METHODS</b>Form November 2011 to December 2012, syndrome typed were 257 male gout in-/outpatients from Affiliated Hospital of Chuanbei Medical College. Another 50 healthy male subjects were recruited as the control. Their clinical and laboratory data were collected. All were excluded from infections and other inflammatory diseases.</p><p><b>RESULTS</b>Four syndrome types existed in gout patients, i.e., intermingled phlegm-stasis blood syndrome (IPSBS), obstruction of dampness and heat syndrome (ODHS), Pi-deficiency induced dampness syndrome (PDIDS), qi-blood deficiency syndrome (QBDS). Of them, 53 acute phase gout patients suffered from IPSBS, 41 from ODHS, 25 from QBDS, and 17 from PDIDS; 41 non-acute phase gout patients suffered from QBDS, 40 from PDIDS, 24 from ODHS, and 16 from IPSBS. Statistical analysis of clinical data showed that, when compared with the normal control group, there was statistical difference in blood routines (WBC, GR, LY, MO) and blood biochemical indices (UA, Ur, Cr, ALT, AST, ALB, GLOB, TG, HDL-C, VLDL-C, apoA, apoB100) of gout patients of different syndromes (P < 0.05, P < 0.01). There was also statistical difference or correlation among different syndromes (P < 0.05).</p><p><b>CONCLUSIONS</b>In the acute phase gout patients, IPSBS and ODHS were dominated, while in the non-acute phase gout patients, QBDS and PDIDS were often seen. In patients of IPSBS and ODHS, inflammation and immune response were more obvious, indicating that better efficacy might be achieved by clearing heat and removing blood stasis associated anti-inflammatory and immune regulation therapies. In patients of QBDS and PDIDS, impaired renal functions were more significant, indicating that better efficacy might be achieved by invigorating Pi and tonifying Shen dominated treatment.</p>
