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, al 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 capil ary, formation of endothelial cells, reducing no reflow phenomenon.

ObjectiveTo explore the safety and efficacy of endoscopic treatment for choledocholithiasis in patients with decompensated cirrhosis.MethodsA total of 104 cases of choledocholithiasis with decompensated cirrhosis were treated by ERCP in our hospital between January 2001 and March 2011.ChildPugh grading and model for end stage liver diseases (MELD) were investigated pre-ERCP and 2 weeks post-ERCP.Complication and mortality during the follow-up were recorded.ResultsThe success rates of complete stone retrieval was 92.3％ (96/104),and plastic stent was placed in other 8.Major complications ineluded post-ERCP bleeding in 9 cases (8.7％) and pancreatitis in 8 (7.7％ ).MELD score valuated 2weeks after ERCP ( 10.1 ± 6.3 ) was significantly lower than that of pre-ERCP ( 1 1.9 ± 6.2,t =2.22,P ＜0.05).The Child-Pugh grading before ERCP of 104 patients were 28 in grade A (26.9％ ),52 in grade B (50.0％ ) and 24 in grade C (23.1％ ),which was significantly different from those of 2 weeks after ERCP (40/52/12).No death was recorded during hospital stay for choledocholithiasis,and 2 patients of Child-Pugh grade C died in 3 months after discharge.ConclusionERCP is an effective method for choledocholi-thiasis in patients with decompensated cirrhosis.The main severe complication was post-ERCP bleeding.Those patients with decompensated cirrhosis would benefit from ERCP if we took effective measures.

Objective To evaluate the short-term effect of Pipeline embolization device (PED)for the treatment of unruptured wide-necked intracranial aneurysms. Methods From October 2015 to September 2016,15 consecutive patients with unruptured wide-necked intracranial aneurysm (aneurysm neck and aneurysm body ratio ≥0. 5)treated with PED at the Department of Neurosurgery,the Second Affiliated Hospital of Nanchang University were enrolled retrospectively. Their clinical and imaging data were analyzed. Kamran scale was used to evaluate the embolization rate of aneurysms and the changes of the parent arteries. DSA examination was performed again at 6 -12 months after operation. Results Fifteen PED were implanted in 15 patients with unruptured wide-necked intracranial aneurysms,including 13ophthalmic artery aneurysms,1 posterior communicating artery aneurysm,and 1 cavernous sinus aneurysm. The technical success rate was 100% . Immediately after PED implantation,Karman rating of 15 cases were aneurysm grade 2 embolization,parent artery grade A (grade 2a). DSA examination was performed again at 6 - 12 months after operation showed that 14 patients were aneurysm grade 4,parent artery was grade A (grade 4a). One patient (ophthalmic artery aneurysm)underwent the second DSA examinations at 6 and 12 months after operation showed that the residual development of aneurysms. The aneurysm embolization was grade 3, and the parent artery was grade A (grade 3a). No branch artery occlusion was observed. Non of them had neurological deficit. The modified Rankin scale score was 0 in all 15 patients. Conclusion The use of PED in the treatment of unruptured wide-necked intracranial aneurysms has a higher occlusion rate. Its long-term effect still needs further follow-up.
