Objective To investigate the relationship between glycosylated hemoglobin A1 c （HbA1 c） and blood glucose levels of eight different points throughout the day in well-glycemic-controlled medical nutrition therapy （MNT） alone type 2 diabetic pafients. Methods Data were collected as＂ capillary blood glucose value of eight different sample points among sixteen observing days in thirty MNT alone type 2 diabetic patients. The correlation between HbAI c and capillary blood glucose value was evaluated by Pearson＇s correlation method. Results The r-values between HbA1c and capillary blood glucose of 3：00, 6：00, and bedtime （22：00-23：00） were 0. 81,0. 79, and 0. 78, respectively（P 〈0. 001 ）. The best correlation was found between the mean value of 8- point blood glucose value throughout the day and HbA1c （ r=0. 84, P 〈0. 001 ）. Conclustion Fasting blood glucose and postabsorptive blood glucose have better correlations with HbAlc compared with other points in this group of well-glycemic-controlled MNT alone type 2 diabetic patients.

The interaction of the novel tetra-carboxylphenyl calix[4]arene （TCPC） with the bovine heart cytochrome c （Cc） was first investigated by fluorescence spectroscopy and molecular modeling methods. The formation of a stable 1：1 complex was monitored by fluorescence titration, and its binding constant is 1.916 ×10^7 L mol^-1. Molecular modeling reveals the recognition mechanism of TCPC to the Cc surface, that is, the electrostatic interaction drives TCPC to the Cc surface, and the van der Waals interaction orientates TCPC parallel to the cleft of Cc.
