High-mobility-group B1 (HMGB1), an abundant, highly conserved cellular protein, is widely known as a nuclear DNA-binding protein that stabilizes nucleosome formation, and facilitates gene transcription. Recent studies suggested that HMGB1 could be overexpressed and released from cellular nucleosome upon endotoxin and cytokine stimulation, or other stress challenge including burns, shock, as well as infection. Therefore, extracellular HMGB1 might be involved in the pathogenesis of sepsis and subsequent multiple organ dysfunction syndrome. Moreover, experimental data showed that extracellular HMGB1 might play vital roles in nerves development, tumor metastasis, atherosclerosis and restenosis after vascular damage.

Objective To evaluate intraperitoneal Composix Kugel prosthetic patch repair of vental hernia. MethodsThe clinical data of 10 cases were reviewed for the surgical procedures and perioperative management in the use of this technique. ResultsMean operation time was 62 min(ranging grom 43 to 80 min). There was no postoperative wound hematoma and infection except for 1 case with seroma. Follow up of 2 to 19 months found no hernia recurrence. Conclusion Intraperitoneal Composix Kugel patch repair of vental hernia has the advantages of short operative time, minimal invasiveness and rapid convalescence.

AIM To investigate the potential effect of riboflavin on the growth of probiotic strains Bifidobacterium adolescentis ( B. adolescentis) and Bacillus cereus ( B. cereus) . METHODS By means of routine bacterial quantitative culture, Gram's staining, and light microscopy, changes in B. adolescentis and B. cereus counts were detected in the presence of riboflavin at different concentrations (1, 0 5, 0 25, 0 g?L -1 ). RESULTS ①The counts of B. adolescentis increased by 10 to 100 fold in 1g?L -1 riboflavin group after 48 h, and 10 to 390 fold in 0 5 g?L -1 and 0 25 g?L -1 riboflavin groups within 72 h as compared to that without riboflavin supplement. Meanwhile, the chain lengths of B. adolescentis were markedly longer in culture system with riboflavin than those without. ②Compared with 0 g?L -1 riboflavin group, the count of B. cereus increased significantly in 0 5 g?L -1 riboflavin group at 36 h, and in 0 25 g?L -1 riboflavin group within 72 h, while it decreased by 50 to 100 000 fold in 1 g?L -1 riboflavin group within 72 h. Likewise, the chain length of B. cereus was markedly longer in 0 5 g?L -1 and 0 25 g?L -1 riboflavin groups, together with the delayed spore formation of B. cereus. ③The 6 month survival rates of B. adolescentis and B. cereus counts in preparations (depositing at 4℃) with 0 5 g?L -1 riboflavin were much higher than those without riboflavin supplement. CONCLUSION Riboflavin in concentrations of 0 5 g?L -1 and 0 25 g?L -1 could markedly enhance the growth of B. adolescentis and B. cereus. 0 5 g?L -1 riboflavin might be beneficial to improve the survival rate of B. adolescentis as well as B. cereus when storing for a long term.

AIM:To investigate the ameliorative effect of ischemic postconditioning (I-postC) on pia mater microcirculation in rats subjected to cerebral ischemia reperfusion (I/R) and its mechanisms. METHODS:Thirty-two male Wistar rats were randomly divided into sham,I/R,I-postC,and ischemic preconditioning (IPC) groups. The global cerebral I/R injury was induced by shunting carotid artery in rats. Pia mater microcirculation and cerebral microcirculatory perfusion were measured after reperfusion. The content of soluble intercellular adhesion molecule-1 (sICAM-1) in plasma was detected using enzyme linked-immunosorbent assay (ELISA). Myeloperoxidase (MPO),malondialdehyde (MDA),and superoxide dismutase (SOD) in cerebral tissue were detected. The expressions of vascular endothelial cell cadherin (VE-cadherin) and NF-?B p65 in cerebral tissue were assayed by Western blotting. RESULTS:(1) The disturbance of the blood flow in microvessel induced by I/R was improved significantly by I-postC. In addition,I-postC alleviated significantly the decrease in diameters of microvesseles,cerebral microcirculatory perfusion and cerebral VE-cadherin content induced by I/R (P

Objective Thoracic cavity fistula following esophagus carcinoma resection is a serious complication with a high mortality.This study aims at a better therapy for thoracic cavity fistula following esophagus carcinoma resection by summarizing the ex-perience with the four-tube strategy ( jejunal fistula tube, stomach tube, chest drainage tube, and nasal fistula tube) in the treatment of the complication. Methods We retrospectively analyzed the clinical data about 62 cases of thoracic cavity fistula following esopha-gus carcinoma resection, 35 treated with the four-tube strategy ( treatment group) and the other 27 with the three-tube ( stomach tube, chest drainage tube, and nasal fistula tube) method ( control group) .We compared the hospital days, wound healing time, mortality, and incidence of anastomotic stenosis at 6 months after operation between the two groups of patients. Results Compared with the controls, the treatment group showed remarkable decreases in the hospital days (P<0.05), wound healing time (P<0.05), and mortality (P<0.05), but no statistically significant difference was observed in the incidence rate of anastomotic stenosis at 6 months after operation between the two groups of patients ( P >0.05 ) . Conclusion Compared with the three-tube method, the four-tube strategy has the advantages of shorter healing time and lower mortali-ty, and therefore is preferable for the treatment of thoracic cavity fis-tula following esophagus carcinoma resection.

Objective To evaluate the application of tubular stomach gastroesophagostomy on the life quality after esophagectomy surgery.Methods From March 2011 to September 2011,66 cases of esophageal cancer patients were divided in two groups in randomized principles.Tirty-four cases in group of tubiform gastro surgery whose the stomach was cut into tubiform stomach in width of 4 cm.And 32 cases of conventional group and whose surgery method was adopted to maintain whole stomach but cut the cardia.And then,using statistical methods,life quality after esophagectomy (treatment related symptoms,general symptoms,daily life,social life,emotional activities) and the perioperative complications were evaluated in 3,6,12,24 months in comparison and analysis.Results Sixty-six surgeries of both group patients were successfully performed,tumor resection rate was 100%,and there was no intraoperative accident also no perioperative death.There was no statistical significance of perioperative complications of 2 groups (P > 0.05).Life quality of tubiform gastro group had improved apparently more than conventional group at the 3rd,6th,12th and 24th month after surgery(78.68 ±2.23 vs 65.94± 4.13,83.79 ± 2.40 vs 66.84 ± 5.86,86.41 ± 1.94 vs 67.09 ± 4.43,89.02 ± 1.71 vs 68.88 ±3.53,P<0.05).At each time point,there were statistically significant differences between tubiform gastro group and conventional group on treatment related symptoms,general symptoms,daily life,emotion activities (P <0.05).At the 3rd,6th month after surgery,tubiform gastro group and the conventional group had no statistically significant difference in the aspect of social life (P>0.05).In the conventional group,the evaluation of quality of life at each time point after surgery and before a point in time in the same group showed no statistical significance (P>0.05).Conclusion Tubiform gastro esophagectomy has a positive influence on life quality of patients of esophageal cancer after surgery prospectively.
