Liver is the main target organ of the metastasis of colorectal cancer.More and more researches demonstrate that including micro-environment of cancer,signal transduction pathway,abnormality of chromosomes and the gene which control cell proliferation and apoptosis are the most important mechanisms in liver metastasis of colorectal cancer.The metastasis of colorectal cancer is the result of all these factors.To study the mechanism can shed some light on prevention and therapy in liver metastasis of colorectal cancer.

OBJECTIVETo investigate the effects of E 4031, a sodium calcium exchanger (NCX) agonist, on the isolated cardiac function and resting Ca2+ level in myocardial cells from rats with chronic heart failure.

METHODSRats chronic heart failure model was established by abdominal aorta coarctation with; Isolated heart perfusion by Langendorff apparatus was used to detect heart function and the effects of E 4031 on haemodynamic indexes; Myocardial cells of rats in the model group were extracted quickly and co-incubated with calcium fluorescent indicator fluo3/AM and the impact of E 4031 on the fluorescence intensity in myocardial cells were evaluated by confocal microscopy.

RESULTSHeart function of rats in the model group detected by Langendorff perfusion was significantly reduced after 12 weeks, E 4031 at 10 micromol/L could improve their left ventricular developed pressure(LVDP) and systolic / diastolic maximum rate (+/- dp/dtmax). Compared with the control and sham operation groups, the resting Ca2+ fluorescence intensity of the myocardial cells of rats in model group was at a higher level and went through a process of transient rise and drop, then stably remaining at a low level after co-incubated with 10 micromol/L E 4031.

CONCLUSIONE 4031 can improve the isolated heart function of rats with chronic heart failure, which may be associated with its enhancing the activity of NCX in the myocardial cell membrane and stabilizing intracellular Ca2+ level.

[Objective]To observe expression of inducible nitric oxide synthase and peroxynitrite anion around the prostheses,and study the relationship between the osteolysis and inducible nitric oxide synthase peroxyni-trite.[Method]Interface tissues were obtained at three Delee-Charnley acetabular sections and seven Gruen femur sections in six revision total hip arthroplasty surgery. The tissues were prepared for immunohistochemical assays to determine the expression of iNOS and nit rotyrosine (NT)-a specific“footprint”of peroxynitrite. Pre-revision X-ray films were observed to determine the incidence of osteolysis regions and non-osteolysis regions. The correlation between the positive cells and the severity of osteolysis were analyzed and compared.[Result]Data showed that zone Ⅲ has much higher iNOS positive immunostaining than that of zone Ⅰ and Ⅱ at acetabulum, and the expression of zone 1、2、6、7 was significantly higher than the other zone at femur(P

Objective To investigate the roles of cell apoptosis and the gene expressions of Fas, FasL, bcl-2 and bax in acute rejection of pancreaticoduodenal transplantation and to evaluate the function of duodenum biopsy for early detection of rejection in rats. Methods Wistar and SD rats were divided into two groups: ①Wistar rats that underwent allogenic pancreaticoduodenal transplantation from the organs of SD rats; ②Wistar rats that received homogenic transplantation. The grafts were then harvested on day 3, 5 and 7 after the transplantation, and all graft samples were observed with HE staining and TUNEL was also used to detect apoptotic cells. The expressions of Fas, FasL, bcl-2 and bax were measured by immunochemical method. According to Nakhleh’s score, pathologic features of transplanted pancreas and duodenum were ranged from one to three scores in order. Results The percentage of same or different scores between the pathological scores of pancreas and duodenum in allogenic pancreaticoduodenal transplantation group were 61.1% (11/18) and 38.9% (7/18) respectively, and there were 6 specimens of pancreatic tissue got higher scores with only one higher score for duodenum. There were significant differences of histopathologic rejection scores and apoptotic indices between the two groups, respectively (P

Objective To explore the water quality of the product water from the centralized water supply system in Hunan, 2006. Methods The sanitary quality of the product water samples collected from 28 centralized water supply system in cities and 39 centralized water supply system in counties in Hunan, 2006, which distributed among the area of Xiangjiang River, Zishui River, Yuanjiang River and Lishui River, were determined and evaluated according to the Standards for Drinking Water Quality (GB5749—2006). Results The eligible rate of the water sample was 70.1%. Among 74 water quality indexes, 12 indexes (such as antimony,aluminum,pH value,manganese and so on) exceeded the standard limits in degrees in some centralized water supply systems. Most of the routine indices of water quality were unqualified and the reference indices were qualified. The quality of some water samples presented statistical difference in some indices (such as aluminum, sulphate, arsenic, et al) among 4 different river areas in Hunan province (P

[Objective]To observe whether erythromycin and alendronate are effective in treating aseptic loosening in a murine osteolysis model. [Method]Air pouches were established in the back of BALB/c mice by injecting sterile air subcutaneously. After the air pouches were mature, grafts of calvaria from syngeneic mouse donors were implanted in the air pouches and polyethylene debris was injected into the air pouches. Mice were divided into 4 groups. In the first group, saline was injected into the air pouches.In the other three groups, polyethylene debris was used. Saline,erythromycin and alendronate were injected intraperitoneally separately.Pouch tissues were collected at 14 days after polyethylene debris administration for molecular and histologic analysis.[Result] Both erythromycin and alendronate inhibited osteoclastogenesis and bone resorption, but alendronate was not as effective as erythromycin in anti-inflammation.[Conclusion]Both erythromycin and alendronate can be promising drugs for the treatment of aseptic loosening.

[Objective]To evaluate the outcome inforation provided by two scoring systems after operative treatment of elementary posterior wall fractures of the acetabulum.[Method]Thirty-two patients with elementary posterior wall fracture of the acetabulum were included in the study.Functional outcomes were assessed with use of the eight health dimensions of the short form(SF)-36,and clinical outcomes were evaluated with use of the modified Merle d' Aubign? score.The SF-36 scores were compared with previously reported normal values and the correlation was analyzed between the modified Merle d' Aubign? score and score of each SF-36 health dimension.[Result]The mean modified Merle d' Aubign? score was 16.28 (range 13-18,SD 1.3),indicating overall good-to-excellent clinical results.However,all SF-36 health dimensions were significatly lower than the expected forms,with a significant statistical difference(P
