Metabolic abnormality is correlated with the incidence of colorectal cancer.Metabolic syndrome is consisting of abdominal obesity,dyslipidemia,high blood pressure,sugar metabolic abnormality,and all of these factors are associated with colorectal cancer.Abdominal obesity and sugar metabolic abnormality may be the primary factors causing rectal cancer.Visceral fat is physiologically more active than subcutaneous fat.Visceral fat can produce and secret hormones and cytokines,which are involved in inflammation and metabolism,therefore the amount of visceral fat may directly or indirectly related to the occurrence of colorectal cancer.Obesity acts as a risk factor for colorectal cancer by several mechanisms,including high blood insulin,insulin-like growth factor,and the change of the adipose cytokines concentrations.Metabolic biomarkers may not only provide clues of colorectal carcinogenesis from the point of view of etiology,but also can help to explore new obesity phenotypes that is relevant to incidence risk of colorectal cancer.

Purpose:To investigate the clinicopathological characristics of colorectal mucinous adenocarcinoma (MUC),which is generally bel ieved to have a poor prognosis,in an attempt to assess ways in which the surgica l outcome can be improved. Methods:From 1994 to 2003,1 715 large intestinal cancer patient s underwent operation, among them, 197 patients were with MUC. The clinicopathol ogical parameters and prognosis of MUC and non-MUC were analyzed retrospectivel y. Results:There were no significant differences in sex , tumor si te and size. Patients with MUC had higher rate of serosal invasion (MUC:59.9% vs non-MUC: 35.1%) , invasive type lymph-node involvement (MUC:41.6% vs non-MUC 21.6%). Patients with MUC were of more advanced stage(D stage:MUC :44.1% vs non-MUC: 22.1%). Conclusions:Based on these findings , a more aggressive attitud e toward surgical intervention is recommended , including extensive lymph node d issection and the resection of adjacent organs that seems to be affected microsc opically , to improve the surgical outcome of this clinical entity.

Objective: To investigate the effect of Astragalus on peritoneal macrophages function in stable continuous ambulatory peritoneal dialysis(CAPD) patients. Methods: 28 stable CAPD patients were included in this study.All the patients were treated with peritoneal dialysis fluid containing Astragalus(20 ml/2 L) in vivo for one week.Peritoneal macrophages function such as phagocytosis ratio、bactericidal ratio、excretion of cytokines(TNF-? and NO) and mitochondrial dehydrogenases activity(MTT assay) were examined ex vivo just before and after the treatment. In vitro,peritoneal macrophages isolated from effluent were incubated with RPMI 1640、CDF or CDF containing various concentrations of Astragalus. Then peritoneal macrophages function mentioned above were examined again and compared. Results:No significant difference was found in TNF-? level in effluent between before and after the treatment (100?63)ng/L vs (116?60)ng/L, (P=0.192). While comparing with pre-treatment, peritoneal macrophages function was improved significantly after the addition of Astragalus into dialysate (phagocytosis ratio: (34.8?12.7)% vs (43.4?9.3)%,P0.05).The results in these two groups were significantly lower than those in Astragalus groups(P0.05). While significant decreasing in NO level and mitochondrial dehydrogenases activity were observed in 8% Astragalus groups as compared with those in 2% Astragalus group(P

Objective: To investigate the effect of Astragalus mongholicus injection(AM) on the secretion and mRNA expression of transforming growth factor((TGF-?1)) and basic fibroblast growth factor(bFGF) in cultured human peritoneal mesothelial cells((HPMC).) Methods: HPMC got from patients underwent surgical operation were cultured in vitro.At first,cells from the third passage were incubated with RPMI1640 culture medium containing 0.1% FBS for 24 hours.Then,they were divided into control group,PDS group,AM group 1,AM group 2 and AM group 3 for testing.Each group was supplemented with equal volum of RPMI1640 culture medium containing 20% FBS.After 24 hour incubating,mitochondrial dehydrogenases activity(MTT assay),the levels of TGF-?1 and bFGF in supernatant of the cell culture and the mRNA expression of TGF-?1 and bFGF were detected.Results: Significant decrease of mitochondrial dehydrogenase activities were observed in PDS group as compared with those in control group and AM groups(P0.05).The levels of TGF-?1 and bFGF in supernatant of the cell culture were significantly lower in control group than those in PDS group.Marked lower levels of TGF-?1 and bFGF were found in AM group 1,AM group 2 and AM group 3 as compared with those in PDS group(P0.05).The mRNA expressions of TGF-?1 and bFGF in PDS group increased significantly as compared with those in control group.And significant mRNA expressions of TGF-?1 and bFGF were found in PDS group when compared with those in AM groups(P

Objective:To investigate the effects of Astragalus on the the apoptosis of cultured human peritoneal mesothelium induced by peritoneal dialysis solution(PDS). Methods:Using RPM1640 culture medium as control,PDS group(commercial PDS containing 1.5% glucose without Astragalus),Astragalus group 1(commercial PDS containing 1.5% glucose and 1% Astragalus) and Astragalus group 2(commercial PDS containing 1.5% glucose and 2% Astragalus) were tested to explore the apoptosis of cultured human peritoneal mesothelial cell in each group.The activity of caspase-3,the terminal deoxynucleotidyl transferase(TdT) mediated dUTP nick end labeling(TUNEL) and flow cytometry analysis were used in apoptosis analysis in this study. Results: The activity of caspase-3 in the control group was defined as 1,the relative activity of caspase-3 in PDS group、 Astragalus group 1 and Astragalus group 2 were 3.26?0.91,(1.87?)0.43 and 1.67?0.32 respectively.The activity of caspase-3 in PDS group was significantly higher than those in the Astragalus group 1 and Astragalus group 2(P

ObjectiveTo study the effect of the rehabilitation nursing and movement training on patients after cardiac valve surgery.Methods26 cases who accepted cardiac valve surgery were assessed with psycho-physiological and cardiac function, then make single rehabilitation nursing measures. Movement training was being done for 20 days as well as mental convalescence and health education of rehabilitation.ResultsCardiac function of all cases was promoted 1-2 grade after rehabilitation. Exercise stress was raised and movement time was prolonged than that of before rehabilitation (P<0.01). The heart rate, systolic pressure, diastolic pressure, binomial product (HR×SBP) ane the lowered S-T segment were also improved significantly after rehabilitation whether in the state at rest or motion with equal time and stress (P<0.01-0.05).ConclusionsRehabilitation nursing and movement training can reduce complications after cardiac valve surgery, raise cardiac reserve, and lower myocardial oxygen consumption. Meanwhile, it can improve myocardial ischemia and raise cardio-pulmonary function. It also can improve quantity of patients' life.

Objective To explore the effects of osteoblasts on the recovery of hematopoiesis and angiogenesis in acute irradiation injury mice.Methods The femurs of 18 male BALB/c mice were used to prepare the bone marrow osteoblasts, and the rest mice were divided into 3 groups as normal group, saline group and osteoblast group.The mice in normal group received no treatment, and the other two groups were received 6.0 Gy 60Co γ-ray irradiation.After irradiation each mouse of osteoblast group was administered with 2 × 106 osteoblasts through tail vein injection, and equal volume saline was given to each mouse of saline group by the same way.The following factors were measured at 7, 14, 21 d after irradiation, they were the counts of peripheral blood cells and bone marrow mononuclear cells ( BMMNC ) , the percentage of CD34 + cells in BMMNC, the histology changes and micro vascular density (MVD) of bone marrow tissue.Results The counts of peripheral blood cells, BMMNC and hematopoietic tissue area in osteoblast group were higher than those in saline group.The percentage of CD34 + cells in BMMNC and the MVD of bone marrow in osteoblast group were also higher than those in saline group at 7, 14, 21 d after irradiation ( t = 2.46 - 64.51, P ＜ 0.05 ).Conclusions Osteoblasts could significantly promote the recovery of hematopoiesis and angiogenesis in mice after acute irradiation injury.
