BACKGROUND:Resuscitative endovascular balloon occlusion of the aorta(REBOA)can temporarily control traumatic ***,its prolonged use potentially leads to ischemia-reperfusion injury(IRI).Partial REBOA(pREBOA)can alleviate ischemic burden;however,its security and eff ectiveness prior to operative hemorrhage control remains ***,we aimed to estimate the effi cacy of pREBOA in a swine model of liver injury using an experimental sliding-chamber ballistic ***:Twenty Landrace pigs were randomized into control(no aortic occlusion)(n=5),intervention with complete REBOA(cREBOA)(n=5),continuous pREBOA(C-pREBOA)(n=5),and sequential pREBOA(S-pREBOA)(n=5)*** the cREBOA and C-pREBOA groups,the balloon was inflated for 60 *** hemodynamic and laboratory values were compared at various observation time *** samples immediately after animal euthanasia from the myocardium,liver,kidneys,and duodenum were collected for histological assessment using hematoxylin and eosin ***:Compared with the control group,the survival rate of the REBOA groups was prominently improved(all P<0.05).The total volume of blood loss was markedly lower in the cREBOA group(493.14±127.31 mL)compared with other groups(P<0.01).The pH was significantly lower at 180 min in the cREBOA and S-pREBOA groups(P<0.05).At 120 min,the S-pREBOA group showed higher alanine aminotransferase(P<0.05)but lower blood urea nitrogen compared with the cREBOA group(P<0.05).CONCLUSION:In this trauma model with liver injury,a 60-minute pREBOA resulted in improved survival rate and was effective in maintaining reliable aortic pressure,despite persistent *** tolerance time for aortic occlusion in Zone I for non-compressible torso hemorrhage was feasible with both continuous partial and sequential partial measures,and the significant improvement in the severity of acidosis and distal organ injury was observed in the sequential pREBOA.

OBJECTIVE: To provide an objective experimental basis for the gastric mucosa pathological evolution and the transformation of different Traditional Chinese medicine(TCM) syndromes in helicobacter pylori(H. pylori)-related gastric diseases(HPGD) patients, based on the combination of TCM syndrome differentiation, molecular biology and ***: A total of 203 participants were enrolled in this study. The expressions of miR-499/miR-149 and *** infection in the gastric tissues from all participants were detected. The genotyping for miR-499 rs3746444 and miR-149 rs2292832 was ***: In H. pylori positive subjects, the proportion of precancerous gastric lesions(PGL) in liver-stomach disharmony syndrome(LSDS) group was higher than in spleen Qi deficiency syndrome(SQDS) group(P < 0.001);The proportion of gastric cancer(GC) in SQDS group was higher than in spleen-stomach damp-heat syndrome(SSDHS) group and LSDS group(all P < 0.001). We also found C allele of miR-149 rs2292832 was linked to lower risk of gastric atrophy [miR-149 rs2292832 C vs T:adjusted odds ratio = 0.207; 95% confidence interval(0.043-0.989); P = 0.048]. Compared with healthy control(HC) group, the expression of miR-499 was significantly increased in GC group, while the expression of miR-149was significantly decreased in chronic inflammation group,PGL group and GC group(all P < 0.05). Test for trend showed that GC risk was on a rising trend with the increasing expression of miR-499 and decreasing expression of miR-149(both P for trend < 0.05).CONCLUSION: The C allele of miR-149 rs2292832 may be a protective factor for gastric mucosal atrophy. *** may participate in the evolution of benign to malignant gastric mucosa lesions by inducing the overexpression of miR-499 and down regulation of miR-149. In addition, patients with H. pylori infection combined SQDS or LSDS may have higher risk of gastric mucosal malignant lesions.
