BACKGROUND: Clinical limb ischemia-reperfusion with no reflow phenomenon after vascular injury repair seriously affects the prognosis of patients. Therapeutic effect of hyperbaric oxygen in myocardial ischemia reperfusion is exactly confirmed, but hyperbaric oxygen is rarely reported in the treatment of limb ischemia-reperfusion. OBJECTIVE: To detect the expression of vascular endothelial growth factor and intracellular adhesion molecule 1 and to investigate the effect of hyperbaric oxygen on the prognosis of limb ischemia-reperfusion with no reflow phenomenon. METHODS: By clinical screening, cases of main arterial injury of the limbs were selected and subjected to vascular repair for restoring limb blood supply. After surgery, all the cases were randomly divided into two groups (Combined treatment group and surgical group), 16 cases in each group. Combined treatment group was treated with hyperbaric oxygen combined with clinical anticoagulant, antiplatelet treatment; surgical group treated with only postoperative clinical treatment. Another 16 adult healthy volunteers were selected to receive hyperbaric oxygen as hyperbaric oxygen group. Expressions of vascular endothelial growth factor and intracellular adhesion molecule 1 were detected using enzyme-linked immunosorbent assay at 8, 72 hours and 7 days after surgery. RESULTS AND CONCLUSION: In the combined treatment and surgical groups, patients exhibited higher expressions of vascular endothelial growth factor and intracellular adhesion molecule 1 than those in the hyperbaric oxygen group (P < 0.01). After 72 hours, the expression of vascular endothelial growth factor was significantly higher in the combined treatment group than the surgical group (P < 0.01). At 8 and 72 hours, the expression of intracellular adhesion molecule 1 was lower in the combined treatment group than the surgical group (P < 0.05). These findings suggest that hyperbaric oxygen can induce high expression of vascular endothelial growth factor and inhibit intracellular adhesion molecule 1, which is crucial for improving growth of blood capillary, formation of endothelial cells, reducing no reflow phenomenon. © 2014 Journal of Clinical Rehabilitative Tissue Engineering Research.

Osteopontin (OPN) plays an important role in the development and progression of some tumors. The polymorphisms of OPN probably change its expression and contribute to interindividual differences of susceptibility to some cancers. The purpose of the present study was to explore the association of rs9138 (+1239; 3′UTR: 3′untranslated regions) and rs1126616 (+750; exon 7) polymorphisms located in the OPN gene with colorectal carcinoma (CRC) susceptibility and to investigate the correlation of the polymorphisms, plasma levels of the OPN protein, clinicopathologic parameters, tumor markers, and lipid. The genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism. The plasma levels, tumor markers, and lipid were measured by enzyme-linked immunosorbent assay. The results indicated that genotype AA and AC of rs9138 and CC and CT of rs1126616 were associated with increased risk of CRC. The allelic frequencies of rs9138A, rs1126616C, and the haplotype (A-C) were associated with increased risk of CRC. Although there was no significant difference of plasma levels in various genotypes, increased plasma protein expression in CRC patients compared with controls was found. Our results suggested that the rs9138 and rs1126616 of OPN were associated with CRC risk, and the OPN protein in plasma may be a potential tumor marker of CRC. © Mary Ann Liebert, Inc.

BACKGROUND: Surgical site infection of instrumented thoracolumbar spine is not rare and may induce serious consequences. There’s controversy about whether to remove the internal fixation in the treatment of infection. OBJECTIVE: To evaluate the safety of the treatment for surgical site infection of thoracolumbar spine without removing internal fixation. METHODS: A total of 358 patients underwent thoracolumbar internal fixation in Department of Orthopedics, the Fourth People’s Hospital of Zigong City, between March 2008 and December 2012. Among them, 13 cases appeared surgical site infection of instrumented thoracolumbar spine, including 5 males and 8 females. The average age of the 13 cases was 54.5 years (31-65 years). After patients were treated with aggressive debridement, irrigation and anti-infective therapy, the wound healings were evaluated. The hemanalysis, erythrocyte sedimentation rate, C-reactive protein and visual analogous scale score were analyzed and compared before debridement and 6 months after debridement. RESULTS AND CONCLUSION: The 13 patients had surgical site infection of instrumented thoracolumbar spine during 1 to 13 months post-operation. After timely diagnosis, aggressive debridement and irrigation, as well as sensitive antibiotic therapy, 12 patients succeeded in curing infection and retaining implants. 1 patient with T12 fracture removed the fixation and cured infection. The follow-up time was 8-40 months, no case recurred. The hemanalysis, erythrocyte sedimentation rate, C-reactive protein and visual analogous scale score showed significant difference before debridement and 6 months after debridement (P < 0.05). Postoperative infection after thoracolumbar internal fixation should be timely diagnosis and receive surgical treatment. Through aggressive debridement, irrigation and sensitive antibiotic therapy, most patients can be cured without removing internal fixation. © 2015, Journal of Clinical Rehabilitative Tissue Engineering Research.

In this study, we tested the hypothesis that the alternating of hypoperfusion and full reperfusion (hypoperfusion postconditioning) could improve neuroprotection on cerebral ischemia in rats and explored the role of TAp63 and ΔNp63 in this process. Eighty male Sprague Dawley rats were randomly divided into 4 groups: the sham group, the cerebral ischemic/reperfusion group (I/R), the hypoperfusion group 1 (HR1), and the hypoperfusion group 2 (HR2). Cerebral ischemia was established by clamping the bilateral common carotid artery with hypotension for 20 minutes. For the rats in the HR1 group, the blood pressure was maintained to 80 to 90 mm Hg in clamping bilateral common carotid artery minutes and then unclamped. For the rats in the HR2 group, the clamping was performed at one side of the common carotid artery and one half of the other side of common carotid artery. Neurologic behavior scores in the I/R, HR1, and HR2 groups decreased significantly after cerebral ischemia, and scores in the HR2 group were significantly higher than those in the I/R group (P < 0.05). Neuronal densities in the HR1 and HR2 groups were significantly higher than that in the I/R group (P < 0.05). Neuronal apoptosis in the HR1 and HR2 groups was significantly lower than that inthe I/R group (P < 0.05). TAp63 and S100β concentration decreased, and ΔNp63 increased significantly in the HR1 and HR2 groups as compared with the I/R group (P < 0.05). No significant difference in these parameters between the HR1 and HR2 groups (P > 0.05). Alternating of hypoperfusion and normal perfusion postconditioning had neuroprotection function on cerebral ischemia in the rats. This could relate with decreasing expression of TAp63 and increasing expression of ΔNp63 in hippocampal region of the first area in the hippocampal circuit to inhibit neuronal apoptosis. © 2014 Mutaz B.
