Objective To investigate the association between HbA1c status,arterial stiffness and endothelial function in subjects with type 2 diabetes mellitus(DM).Methods The study group consisted of 338 DM patients,including 74 subjects with normal HbA1c(≤ 6.0％)(Group A),102 subjects with mildly increased HbA1c(HbA1C increased by less than 6.5％)(Group B)and 162 patients with high HbA1c level (HbA1c increased by more than 6.5％)(Group C).All patients were evaluated for glucose,HbA1c,TC and TG.Pulse wave velocity(PWV)and flow-mediated dialation(FMD)were performed simultaneously.Results Compared with Group A,Group B and C had higher baPWV([1734 ± 343]cm/s vs.[1537 ± 313]cm/s and [1853 ± 364]cm/s vs.[1537 ± 313]cm/s).Patients in Group C had a higher baPWV than those in Group B ([1853 ± 364]cm/s vs.[1734 ± 343]cm/s,P =0.006).The patients in group A had a lower level of FMD than that of group B and C([4.20±3.13]％ vs[5.29±3.92]％,[4.09±2.79]％ vs.[5.29±3.92]％,P＜0.01).Leaner association analysis showed a positive correlation between baPWV and HbAlc(r =0.53,P ＜0.01).baPWV was negatively correlated with FMD(r =-0.25,P ＜0.01).Logistic regression analysis showed that HbA1c(OR32.19％,CI 11.26 ～53.12,P＜0.001),age(OR 14.21,95％ CI 11.43 ～ 17.00,P＜0.001),systolic blood pressure(OR 7.36,95％ CI 6.12-8.59)and TC(OR:0.31,95％ CI:9.97-70.64)were independent predictors for the increased arterial stiffness(baPWV).Conclusion Arterial stiffness parameters varied significantly across subgroups of patients with different levels of HbA1c and the arterial stiffness was positively associated with deranged glucose homeostasis.

This study was aimed to compare the function of dendritic cells (DCs) in patients of Y in-Huang syn-drome and Y ang-Huang syndrome from the peripheral blood of HBV related hepatic failure. Jaundice patients of HBV related hepatic failure were divided into two groups, which were the Y ang-Huang syndrome group and Y in-Huang syndrome group. And a healthy control group was also established. The DCs were separated and cultured in vitro from PBMCs in the peripheral blood. Surface molecules such as HLA-DR, CD80, CD86, CD83 and CD1αwere detected by the flow cytometry. And the level of IFN- α and IL-4 in the supernatant of DCs were also de-tected. The expression difference of inflammatory cytokines and immune cells between Y in-Huang and Y ang-Huang syndrome in patients of HBV related hepatic failure were compared. The results showed that compared with healthy people, the expression rate of DCs phenotype such as HLA-DR, CD1α, CD83, CD80, CD86 in patients of HBV related hepatic failure was significantly decreased (P < 0.01); the excreted factor IFN-α had a significant rising (P < 0.01). Compared to Y ang-Huang syndrome group, the expression rate of CD83 and CD86 in the Y in-Huang syndrome group of HBV related hepatic failure patients was significantly reduced (P < 0.01). And the ex-creted factor of IL-4 had a significant rising in Y in-Huang syndrome group (P < 0.01). Compared to the Y in-Huang syndrome group, the excreted factor IFN-α in the Yang-Huang syndrome group had a significant rising (P< 0.01). It was concluded that DCs function of patients with HBV related hepatic failure in both Y in-Huang syn-drome and Y ang-Huang syndrome group showed low immune function. And the immune function of the Y in-Huang syndrome group was lower. There was excessive releasing of inflammatory factors in the Y ang-Huang syn-drome group. And there was enhanced anti-inflammatory cytokine expression in the Y in-Huang group.

As an endogenous organism protective measure in vivo, preconditioning/ postconditioning in the process of ischemia/reperfusion may play common protective mechanisms, such as reducing the generation of oxygen free radicals, activating adenosine receptor, increasing endogenous nitric oxide and heat shock protein, inhibiting immune inflammatory response and neuronal apoptosis, activating intracellular signal transduction pathways, opening mitochondrial ATP-sensitive potassium channels, as veil as closing mitochondrial permeability transition pores. Investigating the common target of these mechanisms may provide a new theoretical basis for developing new drugs and reducing ischemia/reperfusion injury.
