Diastolic blood pressure, systolic blood pressure, high-density lipoprotein, low-density lipoprotein, body mass index and hyper-sensitive C-reactive protein were higher in diabetes combined with hyperlipidemia group than in diabetes group (P < 0.05).
With the dilution factor increased, the concentrations of serum lipids and anti-CCP, CRP and RF showed the same downward trend, indicating that the detection methods of the above indicators were reasonable and would not be affected by hyperlipidemia.
