ObjectiveIn order to improve the survival of graft liver after liver transplantation, this study was designed to investigate whether intraportal injection of 150mg/kg N-acetylcysteine (NAC) in rats could reduce hepatic ischemia-reperfusion injury after 48 h of cold storage and 2 h of reperfusion. Methods Healthy male Wistar rats weighing 250-350g were used. The study consisted of three groups: control group (group Ⅰ) ;NAC-treated group(group Ⅱ). 1 ml of 5% dextrose (D5%) or 1 ml D5% containing 150mg/ kg NAC was injected into the superior mesenteric vein. 15 min after the injection of D5 % or NAC the liver was flushed with cold (4℃) Ringer' s solution through the portal vein . After perfusion, the liver was removed and kept in 100 ml UW solution at 4℃ for 48 h. In group Ⅲ animals were pretreated with buthionine sulfoximine (BSO) 2 h before intraportal injection of D5 % or NAC and liver harvesting. After cold storage, the livers were then perfused for 2 h by a closed circulating system. Aspartate transaminase (AST), alanine transaminase (ALT), and lactate dehydrogenase (LDH) activities in the perfusate were determined by reflectometry. Lactate and acid phosphatase activities were determined by enzymatic methods. ResultsAfter 48 h of cold storage and 2 h of reperfusion, livers from NAC-treated group produced larger amounts of bile than those in the control group, and released less LDH, AST, ALT and acid phosphatase, a marker of Kupffer cell injury in the perfusate. The protective effects of NAC against cold ischemia-reperfusion liver injury were maintained when animals were pretreated with BSO, a specific inhibitor of glutathione synthesis. ConclusionsThis study shows that intraportal administration of NAC in vivo significantly improves the initial function of the isolated rat liver. Our results also indicate that NAC inhibits the activation of Kupffer cells, which are the first source of reactive oxygen intermediates during reperfusion.

Multiple organ failure (MOF) is a severe complication induced by intra-abdominal sepsis (IAS) in surgical patients. The study was planned to evaluate the role of metabolic support with different formulas of nutrient substants in 42 rabbits of MOF model which was establishei before. The results showed that metabolic support in the early stage of MOF induced by IAS coul increase body weight in varying degree, promote protein synthesis and decrease protein degration in rabbits. Lower non-protein calorie supplied with glucose might decrease stress response, increase nitrogen retention and improve lung function. Overloads of amino acid nitrogen could increase stress response, increase urinary nitrogen excretion and deteriorate the respiratory function.

Objective To evaluate the safety and efficacy of laparoscopy-assisted gastrectomy (LAG) for advanced gastric cancer.Methods The clinical data were retrospectively analyzed in 108 patients undergoing radical LAG for advanced gastric cancer from March 2008 to November 2011.Results 98 out of 108 patients were followed-up,the follow-up rate was 90.7％,with medium follow-up period of 30 months (range 6-70 months).26 patients died and 3 patients developed recurrence during the follow-up period.The overall recurrence rate was 26.9％ (29/108),in which the recurrence rate was 0 for Ⅰ B cases,18.8％ (6/32) for ⅡA,30％ (6/20) for ⅡB,30.8％ (8/26) for ⅢA,and37.5％ (9/24) for ⅢB,respectively.The overall 1,2,3-year survival rates were 95.4％,88.9％,73.8％,and 1,2,3-year progression free survival rates were 93.5％,83.3％,73.8％,respectively.Conclusions Compared with open gastrectomy LAG is a safe and feasible surgical procedure with satisfactory 3-year survival in patients of advanced gastric carcinoma.

Objective To evaluate the long-term effects of postnatal dexamethasone administration in prevention or treatment of chronic lung disease (CLD) in preterm infants.Methods All randomized controlled clinical trials (RCT) on long-term effect of postnatal dexamethasone in prevention or treatment of chronic lung disease in preterm infants were searched in Medline,Embase database,Cochrane Library and Chinese Medical Citation Index database,China National Knowledge infrastructure,VIP Chinese Periodical Database and Chinese Digital Hospital Library and Wanfang Chinese periodical database.As a supplementation,the works of domestic and international pediatric conferences were collected by manual search.The follow-up time was defined as longer than two years.Revman 5.0 was used for Meta-analysis for the effects of dexamethasone on nervous system,respiratory system and mortality.Results Eight RCTs fulfilled the including criteria.Statistical analysis revealed that the incidence of recurrent respiratory disease decreased from 49.7％ to 38.9％ in the dexamethasone group compared to the control group with RR =0.57 (95％ CI:0.37-0.88,P ＜ 0.05).But the incidence of cerebral palsy in dexamethasone group increased significantly (RR =1.95,95％ CI:1.41-2.71,P ＜ 0.01).Stratified analysis revealed that the incidence of cerebral palsy in early-use group (within 1 week after birth) was higher than that in control group (RR =2.59,95％ CI:1.59-4.21,P ＜0.01) ; while the incidence in later-use group (1 week after birth) was not statistically different from that in control group (RR =1.5,95％ CI:0.95-2.36,P =0.08).There were no significant differences in the incidence of mental retardation (RR =0.77,95％ CI:0.28-0.14,P ＞ 0.05),deafness (RR =0.52,95％ CI:0.17-1.56,P =0.24) and severe visual impairment (RR =1.56,95％ CI:0.77-3.18,P =0.22) between dexamethasone group and control group,as well as in mortality rate (RR =0.91,95％ CI:0.71-1.16,P ＞ 0.05).Conclusions Intravenous administration of dexamethasone after birth for prevention or treatment of CLD in preterm infants can reduce the incidence of recurrent respiratory diseases in childhood; meanwhile the incidence of cerebral palsy may increase,it almost occurs in the early dexamethason administration group,not in the late group.Dexamethasone may not reduce the mortality of CLD.

In the early stage of tumor,the diagnosis index of objective and definite is often deficient,which brings great trouble to the treatment.How to find some valuable markers or characteristic changes in the early stage of cancer is the key problem to be solved by the medical experts.With the development of flow cytometry (FCM),it is playing a more and more important role in precancerous lesion screening,early detection of cancer,chemotherapy guidance and prognosis assessment.In personalized medicine and precise medical background,the application of FCM in tumor marker detection,cancer stem cells separation screening,isolation and identification of circulating tumor cells is especially worth looking forward tc.

Matrix metallopeptidase 9 (MMP-9) is a group of enzymes that belong to the zine-metalloproteinases family involved in the pathophysiological process of various diseases,such as inflammation,angiogenesis and tumor invasion.Hypoxia-inducible factor-1 (HIF-1) is a nucleoprotein with transcription activity,which consists of two different subunits,α and β.It plays an important role in the process of the formation of new blood vessels following ischemic necrosis and the process of hypoxia induced cell apoptosis.Silent information regulator2-related enzymes 1 (SIRT1) is a NAD-dependent deacetylase sirtuin,which belongs to a member of the sirtuin family of proteins,also involved in many pathophysiologic processes,such as aging,cell death and tumorigenesis.This study aims to review the role of MMP-9,HIF-1 and SIRT1 in acute lung injury.

Objective: To construct IκBα vector carrying SAA3 promoter and to observe its effect on NF-κB activity and LPS-induced inflammation, so as to lay a foundation for treatment of sepsis. Methods: Mouse liver cells and kupffer cells were co-cultured and were divided into three groups: control group, LPS group and LPS+ gene transfer group. Twenty-four hours after LPS injection, the levels of AST, ALT, LDH, IL-6 and TNF-α were measured in the supernatants of the each group. For animal experiments: (1) Mice were divided into three groups: control group, LPS group and LPS+gene transfer group(n=10). The levels of TNF-α and IL-6 were measured in the serum and liver tissues 24 hours after intraperitoneal injection of 250ug LPS or saline. (2) Mice were also divided into two groups: LPS group and LPS+gene transfer group(n=21). Mice were injected with 150 μg LPS twice at 0 and 48 h, then the activities of NF-κB and IκBα in the liver were measured at 0,2,24,48,50,72, and 96 h after the first injection. The values at 0 h were taken as control group. (3) Mice were also divided into another two groups: LPS group and LPS+gene transfer group(n=20). The survival rates of animals were observed at 0,2,24,48,50,72, and 96 h after injection of 350 μg LPS. Results: Compared with LPS group, the levels of AST, LDH, TNF-α and IL-6 in the culture supernatants of LPS+gene transfer group were decreased, but were still higher than those in the control group(P<0.05). Compared with LPS group, the levels of TNF-α and IL-6 in the liver tissues and sera of LPS + gene transfer group were significantly decreased(P<0.05). Compared with LPS group, the activity of NF-κB in the liver tissues of LPS + gene transfer group were decreased, but was still significantly higher than that of the control group(P<0.05). Compared with LPS group, LPS+gene transfer group had higher survival rate at 72 and 96 h(P<0.05). Conclusion: IκBα gene can be expressed in the liver with SAA3 promoter, and transfection of IκBα can effectively inhibit endotoxin-induced liver and general inflammation.
