BACKGROUND:In the initial stage of ischemia,organisms complete angiogenesis and maintain the blood supply of organization through compensatory regulation and repair,in which process a variety of cytokines,especially vascular endothelial growth factor (VEGF),have played a key role.OBJECTIVE:To observe the characteristics and rules of VEGF level changes in both ischemic tissues and blood serums at different time points after establishing rat models of lower limb ischemia.DESIGN,TIME AND SETTING:A randomized controlled animal experiment was performed at the Loboratory for Key Subjects in Dongzhimen Hospital and the Laboratory of Molecular Biology in Beijing University of Chinese Medicine from April to November in 2007.MATERIALS:A total of 42 male SD rats of 4 weeks were divided by random digits table into 6 groups,namely a control group and a model group which was subdivided into 5 groups at the time points of hour 4,day 3,weeks 1,2 and 4 post modeling respectivly.METHODS:Rat models of lower limb ischemia were established in the model group by performing ligation and mutilation operation to left femoral arteries of rats that were anesthetized with 100 g/L chloral hydrate. At the time points of hour 4,day 3,weeks 1,2 and 4 following modeling respectively,rats were selected to extract their abdominal aorta blood samples whose supernatant was then obtained through 10 minutes of 3 000r/min centrifugalization. Gastrocnemius tissues in left legs of rats were isolated at the same time. Samples in control group were obtained directly from anesthetized rats.MAIN OUTCOME MEASURES:Western blotting method was used for detecting protein expression of VEGF in ischemic tissues and ELASA method for VEGF level in serum.RESULTS:The protein expression of VEGF in ischemic tissues began to increase immediately at hour 4 following ischemia and reached a peak at day 3,after which it reduced gradually till week 2 when it reached its minimum. Then it began to increase again and reached the level close to that of normal tissues by the end of week 4 following ischemia. As for the VEGF level in serum,it decreased immediately after ischemia,with the maximum decrease amplitude between immediate and hour 4 following ischemia,a smaller one between hour 4 and week 1;From week 1 following ischemia on,it began to increase but was still lower than the normal level by the end of week 4 (P＜0.01 ).The VEGF level in serum changed with the tendency of immediate decrease from hour 4,minimum at week 1 and graduate increase after week 1 following ischemia.CONCLUSION:After ischemia in lower limb,VEGF level in ischemic tissues changes in the direction of increase-decrease-increase;VEGF level in serum changed in the direction of decrease-increase. In another words,VEGF levels after ischemia shows the characteristics of being low in serum and high in local ischemic tissues.

ObjectiveTo investigate the relationship between tumor-infiltrating mast cell (TIM) and the clinicopathological and prognostic factors of patients with colorectal cancer.MethodsA total of 282 cases of paraffin-embedded colorectal cancer specimens were obtained from the First Affiliated Hospital of Sun Yat-sen University from January 2002 to December 2005.The density of TIM was determined by immunohistochemical staining.According to the mean TIM density detected [ ( 8.4 + 6.5 )/HPF ],all the patients were divided into low-TIM density group (mean TIM density ＜8.4/HPF) and high-TIM density group (mean TIM density ＞8.4/HPF).The clinicopathological factors and the prognosis of patients between high-TIM density group and low-TIM density group were compared.All data were analyzed using the t test or chi-square test.The survival curve was drawn using the Kaplan-Meier method,and the survival of the patients was analyzed by the Log-rank test.The clinicopathological factors were analyzed retrospectively with the univariate and multivariate COX regression model.ResultsTIM was detected in all the patients with colorectal cancer.Significant differences were observed in the number of patients in N stage and TNM stage between patients in the high-TIM density group and those in the lowTIM density group (x2 =6.025,7.410,P ＜ 0.05 ).All patients were followed up till September 2010,the 5-year overall and tumor-free survival rates of patients were 82.9％ and 63.1％ in the low-TIM density group,79.0％ and 59.3％ in the high-TIM density group,with significant difference between the 2 groups (P ＜ 0.05 ).COX proportional hazard regression model revealed that high density of TIM was associated with short overall survival time and tumor-free survival time of colorectal cancer patients ( RR =2.119,95 ％ CI 1.326- 3.386; RR =2.084,95 ％ CI 1.357-3.199,P ＜0.05).The resuhs of multivariate analysis showed that high density of TIM was the independent factor influencing the overall survival time and tumor-free survival time (RR =1.651,95％ CI 1.009-2.702; RR =1.680,95％ CI 1.074-2.629,P ＜ 0.05 ).ConclusionHigh density of TIM is correlated with the N stage and TNM stage of colorectal cancer,and it is an independent predictor of poor survival for patients with colorectal cancer.

Objective To investigate the association of polymorphisms of arylhydrocarbon receptor (AhR) - 1661G/A with glutathione S-transferase pi ( GSTP1 ) - 313A/G and the susceptibility to endometriosis in southern Han Chinese.Methods Total of 432 endometriosis patients undergoing laparoscopic or laparotomy surgery matched with 493 patients with fallopian tube ligation,tubal recanalization,laparoscopic hydrotubation,benign ovarian tumor and teratoma surgeries without endometriosis as control group were enrolled in this study.The single nucleotide polymorphism (SNP) of AhR -1661G/A and GSTP1 -313A/G were detected by using a fluorescent quantitative PCR-based high resolution melting (HRM).Results The numbers of combined genotypes AhR - 1661G/A and GSTP1 -313A/G were 120 patients with AG + AA,64 patients with AG + AG,8 patients with AG + GG,109 patients with GG +AA,84 patients with GG + AG,4 patients with GG + GG,31 patients with AA + AA,10 patients with AA + AG,1 patient with AA + GG at endometriosis group and 131 patients with AG + AA,68 patients with AG + AG,6 patients with AG + GG,157 patients with GG + AA,66 patients with GG + AG,4 patients with GG + GG,35 patients with AA + AA,20 patients with AA + AG,3 patients with AA + GG at endometriosis group.There was no statistically different frequencies of genotypes between endometriosis group and control group (x2 = 12.558,P = 0.128 ).Compared with genotype GG + AA,the risk of endometriosis with genotype GG + AG was increased 1.833 time (95％CI:1.233-2.274).Conclusion The combined genotype GG + AG [ from AhR - 1661G/A (GG) and GSTP1 - 313A/G (AG) ] might be related with susceptibility to endometriosis.
