Objective Increased serum uric acid level is associated with type 2 diabetes (T2DM) through the mechanism of oxidative stress.As the rate-limiting enzyme in the degradation of purines in humans,xanthine oxidoreductase (XOR)catalyzes the final two reactions of purine catabolism,oxidizing hypoxanthine to xanthine,and xanthine to uric acid.The aim of this study is to investigate the association between serum XOR activity and T2DM.Methods A total of 270 patients with T2DM and 140 age-and-gender-matched health controls were enrolled in the study.The clinical examinations such as weight and height were conducted in the morning after an overnight fast.Serum XOR activity and other biochemical parameters like triglyceride,total cholesterol,high density lipoprotein cholesterol,fasting plasma glucose and uric acid levels were measured.Results Serum XOR activity was significantly elevated in T2DM patients compared with that in the controls (31.2 ± 8.91 vs 4.6 ± 0.91 U/L,P ＜0.01).Serum XOR activity was significantly elevated in T2DM patients complicated with lower extremity arterial disease compared to that in patients without lower extremity arterial disease (42.1 ± 8.43 vs 23.7 ± 5.31 U/L,P ＜ 0.01).Conclusion High XOR activity plays an important role in onset and development of T2DM.

Objective To investigate the effect of chloroform extract of Zingiber mioga Roscoe on human dermal microvascular endothelial cell (HDMEC) expression of cell adhesion molecules and adhesivity to lymphocytes.Methods HDMECs were isolated from human foreskin tissue and subjected to subculture.After several passages,some HDMECs were treated with chloroform extract from Zingiber mioga Roscoe (CFMG) of 200 mg/L for 30 minutes before or after 24-hour stimulation with tumor necrosis factor (TNF)-α or interleukin (IL)-1α.Subsequently,enzyme-linked immunosorbent assay was performed to determine the expression levels of intercellular adhesion molecule-1 (ICAM-1),vascular cell adhesion molecule-1 (VCAM-1) and E-selectin on HDMECs.Both T lymphocytes isolated from venous blood of healthy adults and Ramos Burkitt's lymphoma B cells were labelled with chromium-51 and incubated with the HDMECs for four hours followed by the determination of radiation intensity of lymphocytes adhering to HDMECs using a gamma-counter.Results Compared with 0.2％ dimethyl sulfoxide (DMSO),CFMG slightly down-regulated the expression of ICAM-1,VCAM-1 and E-selectin on resting HDMECs (all P ＞ 0.05).In comparison with culture medium,TNF-α enhanced the expressions of ICAM-1,VCAM-1 and E-selectin significantly (all P ＜ 0.01),and IL-1α elevated the expressions of ICAM-1 and E-selectin markedly(both P ＜ 0.01) as well as the expression of VCAM-1 slightly (P ＞ 0.05).The upregulating effects of TNF-α and IL-1α on the expressions of adhesion molecules were notably suppressed by the CFMG treatment prior to the stimulation with TNF-α and IL-1α(all P ＜ 0.01),but not affected by that after the stimulation (all P ＞ 0.05).The adhesivity of HDMECs to T lymphocytes and Ramos cells was slightly decreased by CFMG treatment compared with 0.2％ DMSO (both P ＞ 0.05),but was markedly increased by TNF-α and IL-1α compared with the culture medium (both P ＜ 0.01).Conclusions CFMG may play an antiinflammatory role via blocking the up-regulating effect of pre-inflammatory cytokines such as TNF-α and IL-1α on the expression of adherence molecules on HDMECs and,hence,inhibiting inflammatory cell infiltration in tissue.

The diabetic rats reduced by STZ were treated with the same decoction for 4 weeks, at the end of the experiments the nerve conduction velocity (NCV) and the activity of aldose reductase (AR) were measured.Results: Some symptoms such as acra pain, numbness, asthenia and the peroneal SNCV were significantly improved after treatment with decoction. The animal experiments showed that the NCV were significantly increased and the activity of AR significantly decreased in diabetic rats as compared with the normal rats.Conclusion: Shuanghongtong Decoction could improve the symptom and increase the NCV of DPN. It's mechanism may be through inhibiting the activity of AR then improving the diabetic metabolism disorder.

Objective To investigate the relationship between CD158j expression and phosphorylated ERK (p-ERK) in CD4+ CD28null T cells in cerebral infarction (CI) patients- with carotid atherosclerosis and its effects on carotid atherosclerotic plaque stability. Methods Percentage of peripheral CD4+ CD28null and the expression of CD158j and perform on CD4+ CD28null cells was analyzed with flow cytometry in 106 CI patients with carotid atherosclerosis, 33 CI patients with normal carotid arteries and in 50 normal controls, respectively; p-ERK expression was assayed with flow cytometry in 36 CI patients with unstable plaque, and serum IFN-γ was detected with ELISA. The intima-media thickness (IMT) of bilateral carotid arteries in all subjects was confirmed by the colour Doppler ultrasonograph imagingResults Percentage of the CD4+ CD28null T cells, expression of CD158j and perform on CD4+ CD28null T cells and the serum IFN-γ levels was dramatically higher in CI patients than that in normal controls, respectively (all P <0.01), which was decreased in an order of CI patients with patients with unstable plaque, stable plaque, carotid artery IMT and with normal carotid artery. A strong positive correlation was observed between the CD158j expression and degree of p-ERK in CI patients with unstable plaque (P < 0. 01). Conclusion CD4+ CD28null T cells were significantly increased in CI patients with carotid atherosclerosis. CD158j might up-regulate p-ERK expression and induce the proliferation of the CD4+ CD28nullT cells; consequently, higher cytokine production such as IFN-γ produced by CD4+ CD28null T cells may cause the formation of unstable plaque.
