Objective:To investigate the possible association between Thr241Met polymorphism in the DNA repair gene X-ray repair cross-complementing group 3 (XRCC3) with genetic susceptibility to glioma in a Chinese Han population living in Shanghai and the surrounding provinces in east China. Methods: Genotyping by a TaqMan assay was performed in 771 brain glioma patients living in Shanghai and the surrounding provinces (Jiangsu.Zhejiang, Anhui.etc. )and in 752 control participants matched in age and gender. The genotyping results of TaqMan assay and the association between Thr241Met polymorphism in the DNA repair gene XRCC3 with genetic susceptibility to glioma were statistically analyzed. Results: Genotypes of 1 468 subjects (760 with brain glioma and 708 were cancer-free control) were successfully performed by TaqMan assay, with the successful rate being 96.4%. Statistical analysis result showed that gene(C/T) and genotype(C/CT/CT/T) frequencies of XRCC3 were not significantly different between the glioma and cancer-free groups. Compared with the CC genotype, the variant TC(P = 0. 909; adjusted by age and gender OR = 0. 981; 95%CI = 0. 701-1. 371) or TT(P=0. 642; adjusted by age and gender OR = 0. 7; 95%CI = 0. 156-3. 146) genotypes of XRCC3 Thr241Met were associated with a non-statistically significant increase of glioma risk. Conclusion: The variant TC or TT genotypes of XRCC3 Thr241Met may not be risk factors for brain glioma in Chinese Han population living in Shanghai and the surrounding provinces in east China.

Objective To compare the effects of mild hypothermia induced in different time courses on rats subjected to 3 hours (h) of ischemia followed by 3 h or 72 h of reperfusion.Methods Eighty male Sprague-Dawley rats were divided into three mild hypothermic (MHT, 32±0.2℃) groups, including intra-ischemia (MHTi), intra-reperfusion (MHTr), and intra-ischemia/reperfusion (MHTi+r) group, and one normothermic group (NT, 37±0.2℃) as the control. Reversible focal ischemia was carried out in rats with suture model. The cortical blood flow was measured during 3 h of ischemia followed by 3 h of reperfusion. The permeability of brain blood barrier (BBB) was estimated after 3 h of reperfusion. The infarct volume was measured at 72 h after reperfusion to determine the effects of MHT. Results The acute post-ischemic hyperperfusion and delayed hypoperfusion in ischemic perifocal region and sustained hypoperfusion in ischemic core were inhibited in MHTi+r and MHTi rats (P<0.05). MHTi+r protection on post-ischemic progressive hypoperfusion in the perifocal region was more effective than that of MHTi (P<0.05). The BBB disruption and the infarct volume were significantly reduced in both MHTi and MHTi+r groups (P<0.05), especially in the MHTi+r rats.Conclusions This study demonstrates that MHTi+r has more substantial protective effects on reducing ischemia/reperfusion injury than MHTi. It may inhibit post-ischemic hyperperfusion and delayed or sustained hypoperfusion in ischemic perifocal regions, and reduce brain blood barrier disruption in the cortex region.

Poly (hydroxyethyl methacrylate) (PHEMA) hydrogel for intraocular lens (IOL) materials was synthesized by solution polymerization using 2-hydroxyethyl methacrylate (HEMA) as raw material, ammonium persulfate and sodium pyrosulfite (KPS/SMBS) as catalyst, and trietyleneglycole dimethacrylate (TEGDMA) as cross-linking additive. Effects of reaction time, temperature, dosage of catalyst and cross-linking additive on mechanical strength and the equilibrium water content (EWC) of the PHEMA hydrogel were systematically investigated and their structure and optical property were also characterized. The experimental results showed that the optimum conditions for preparing PHEMA hydrogel are: catalyst 0.5 wt%, cross-linking additive 1.0 wt%, reaction temperature 40 degrees C, reaction time 36 h. Under the optimum conditions, the tensile strength of PHEMA hydrogel prepared is as high as 0.57 MPa, hardness of Shore A is 23.0, EWC is over 40%, and light transmittance is over 97%.
