AIM: To investigate the protective effect of melatonin on liver after intestinal ischemia-reperfusion injury in rats. METHODS: One hundred and fifty male Wistar rats, weighing 190-210 g, aged 7 wk, were randomly divided into melatonin exposure group, alcohol solvent control group and normal saline control group. Rats in the melatonin exposure group received intraperitoneal (IP) melatonin (20 mg/kg) 30 min before intestinal ischemia-reperfusion (IR), rats in the alcohol solvent control group received the same concentration and volume of alcohol, and rats in the normal saline control group received the same volume of normal saline. Serum samples were collected from each group 0.5, 1, 6, 12, and 24 h after intestinal IR. Levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured with an auto-biochemical analyzer. Serum TNF-α was tested by enzyme-linked immunosorbent assay (ELISA). Malondialdehyde (MDA) in liver was detected by colorimetric assay. Pathological changes in liver and immunohistochemical straining of ICAM-1 were observed under an optical microscope. RESULTS: The levels of ALT measured at various time points after intestinal IR in the melatonin exposure group were significantly lower than those in the other two control groups (P < 0.05). The serum AST levels 12 and 24 h after intestinal IR and the ICAM-1 levels (%) 6, 12 and 24 h after intestinal IR in the melatonin exposure group were also significantly lower than those in the other two control groups (P < 0.05). CONCLUSION: Exotic melatonin can inhibit the activity of ALT, AST and TNF-α, decrease the accumulation of MDA, and depress the expression of ICAM-1 in liver after intestinal IR injury, thus improving the liver function.

AIM: To review the application of nutrition support in patients after surgery for colorectal cancer, and to propose appropriate nutrition strategies. METHODS: A total of 202 consecutive surgical patients admitted to our hospital with a diagnosis of colon cancer or rectal cancer from January 2010 to July 2010, meeting the requirements of Nutrition Risk Screening 2002, were enrolled in our study. Laboratory tests were performed to analyze the nutrition status of each patient, and the clinical outcome variables, including postoperative complications, hospital stay, cost of hospitalization and postoperative outcome, were analyzed. RESULTS: The "non-risk" patients who did not receive postoperative nutrition support had a higher rate of postoperative complications than patients who received postoperative nutrition support (2.40 ± 1.51 vs 1.23 ± 0.60, P = 0.000), and had a longer postoperative hospital stay (23.00 ± 15.84 d vs 15.27 ± 5.89 d, P = 0.009). There was higher cost of hospitalization for patients who received preoperative total parenteral nutrition (TPN)than for patients who did not receive preoperative TPN (62 713.50 ± 5070.66 RMB Yuan vs 43178.00 ± 3596.68 RMB Yuan, P = 0.014). Applying postoperative enteral nutrition significantly shortened postoperative fasting time (5.16 ± 1.21 d vs 6.40 ± 1.84 d, P = 0.001) and postoperative hospital stay (11.92 ± 4.34 d vs 15.77 ± 6.03 d, P = 0.002). The patients who received postoperative TPN for no less than 7 d had increased serum glucose levels (7.59 ± 3.57 mmol/L vs 6.48 ± 1.32 mmol/L, P = 0.006) and cost of hospitalization (47 724.14 ± 16 945.17 Yuan vs 38 598.73 ± 8349.79 Yuan, P = 0.000). The patients who received postoperative omega-3 fatty acids had a higher rate of postoperative complications than the patients who did not (1.33 ± 0.64 vs 1.13 ± 0.49, P = 0.041). High level of serum glucose was associated with a high risk of postoperative complications of infection. CONCLUSION: Appropriate and moderate nutrition

Protective effect of ischemic preconditioning on hepatic ischemia-reperfusion injury by advancing the expressive phase of survivin in rats

引用

Hepatobiliary & Pancreatic Diseases International 2008年第6期7卷 615-620页

作者： Li, Jian-Yi Gu, Xi yin, hong-zhuan Zhou, Yong Zhang, Wen-Hai Qin, Yi-Min China Med Univ Shengjing Hosp Dept Gen Surg Shenyang 110004 Peoples R China Shenyang First Peoples Hosp Dept Gen Surg Shenyang 110044 Peoples R China

BACKGROUND: Survivin is a new and important gene in the regulation of apoptosis. It is very important to explore the effect of the expression of survivin protein caused by ischemia-reperfusion (IR) injury. The effect of IR injury caused by ischemic preconditioning (IP) on the liver in rats and the relation between the protective effect of IP and the expression of survivin are unclear. METHODS: One hundred and fifty male Wistar rats (weighing 190-210 g, aged 6-7 weeks) were divided into three groups at random: ischemic preconditioning (IP), ischemia-reperfusion (IR) and sham-operation (SO). Sample specimens were collected from each group at 6, 12, 24, 48, and 72 hours after reperfusion. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured by an automatic biochemical analyzer. Malondialdehyde (MDA) in liver tissue was measured. Pathological changes in the liver and immunohistochemical staining for survivin were determined with an optical microscope. RESULTS: The ALT levels in the IP and IR groups after reperfusion at each time were higher than those in the SO group (P<0.05), whereas after reperfusion for 6 and 12 hours, the ALT levels in the IP group were lower than those in the IR group (P<0.05). The AST levels in all IP and IR groups were higher than those in the SO group (P<0.05), whereas after reperfusion for 12, 24, 48 and 72 hours, the AST levels in the IP group were lower than those in the IR group (P<0.05). The MDA concentrations after reperfusion in the IP group were lower than those in the IR group (P<0.05), though the MDA concentrations in the IP and IR groups increased in contrast to those in the SO group after reperfusion at each time (P<0.05). After reperfusion for 12, 24, 48 and 72 hours, the number of survivin-positive cells was larger in the IP and IR groups than in the SO group (P<0.05). After reperfusion for 12, 24, and 48 hours the number of survivin-positive cells in the IP group increased compared with that in t

The carbyne compound [Br(CO)_2(Py)_2Mo(≡CC_6H_5)] (Py=pyridine) (1a) reacts with Co_2 (CO)_8, Fe_2(CO)_9 and Mn_2 (CO)_(10) to give tetrahedral tri-metal cluster compounds Co_2Mo(μ_3-CC_6H_5)Br(CO)_8(Py)_2 (2), Fe_2Mo(μ_3-CC_6H_5) Br(CO)_9(Py)_2 (3) and Mn_2Mo(μ_3-CC_6H_5)Br(CO)_(10) (Py)_2 (4) respectively. Tri-metal cluster compound Co_2Mo(μ_3-CC_6H_5)Br(CO)_8-(bipy) (bipy=α,α'dipyridyl) (5) is prepared in a similar reaction sequence from [Br(CO)_2(bipy)Mo(≡CC_6H_5)] (1b) and Co_2(CO)_8. IR, ~1H and ^(13)C NMR spectral data of these compounds are reported and discussed. The crystal structure of compound (5) has been determined by X-ray diffraction.
