Objective This study was designed to determine the serum CA-Hb 3 level in human colorectal carcinoma and analyze its clinical significance.Methods The level of serum CA-Hb 3 was measured by ELISA in 72 patients with colorectal carcinoma and 36 normal persons as the control group.Results The level of serum CA-Hb 3 in colorectal carcinoma was significantly higher than that of normal control .The level of serum CA-Hb 3 was positively related with tumor size,clinical pathological staging.With progression of clinical pathological staging (Dukes'stage),the level of CA-Hb 3 increased significantly,but its relation to tumor size,age,and sex was not significant.Conclusion Serum CA-Hb 3 assay may be a potentially valuable marker in assessment of pathological staging and judgement of clinical prognosis of colorectal carcinoma.
4.Effect of homocysteine on secretion and expression of interleukin-6 in cultured rat vascular smooth muscle cells
Chinese Journal of Pathophysiology 1999;0(09):-
AIM: To investigate the effect of homocysteine (Hcy) on secretion and expression of interleukin-6 (IL-6), which is a multifunctional proinflammatory cytokine, in cultured rat vascular smooth muscle cells (VSMCs). METHODS: Rat VSMCs were stimulated with Hcy. Cell ELISA was performed to measure the expression of IL-6 protein and semiquantitative RT-PCR was used to dectect the IL-6 mRNA expression. RESULTS: Compared with control, treatment of 0.25 mmol Hcy for 6 h could increase IL-6 production. In addition, Hcy concentration-dependently increased the expression of IL-6 protein in these cells. 0 1 mmol/L, 0 25 mmol/L Hcy increased IL-6 production 1 4-fold and 3 4-fold, respectively Furthermore, RT-PCR analysis demonstrated that homocysteine also enhanced IL-6 mRNA expression in a concentration- and time-dependent manner.CONCLUSION: Homocysteine can induce IL-6 expression in VSMCs and elicit vascular inflammatory response, which may thereby influence the pathogenesis of atherosclerosis.

Objective To investigate the relationship between smoking and the occurrence of pulmonary tuberculosis among type 2 diabetics(DM-PTB).Methods A hospital-based case-control study was carried out at three hospitals in Tianjin from 2001 to 2002.87 cases of newly-diagnosed pulmonary tuberculosis with type 2 diabetes mellitus and 129 controls by frequency-matched by gander and age were recruited and interviewed.Univariate and multivariate unconditional logistic regression analysis was conducted.The adjusted odds ratio(OR) and 95% confidence interval(CI) were estimated.Results Higher smoking index(OR=1.399,95%CI=1.098~1.782)?beginning smoking at younger(OR=2.028,95%CI=1.076~3.821)?large consumption of cigarets per day(OR=1.349,95%CI=1.087~1.674)?no smoking cessation after diabetes diagnosis(OR=5.327,95%CI=1.703~16.661) were significantly associated with DM-PTB after adjusted for other risk factors.Among female diabetics large consumption of cigarets per day? beginning smoking at younger higher smoking index were generally associated with increased risk of pulmonary tuberculosis;while without smoking cessation after diabetes diagnosis might be risk factor among the male;higher smoking index might increase the risk of pulmonary tuberculosis among younger(youger than 60y) diabetics.Conclusion Smoking control or cessation among type 2 diabetics might decrease the risk of pulmonary tuberculosis.
7.Role of mitogen-activated protein kinase in myocardial hypertrophy
Chinese Journal of Pathophysiology 2000;0(07):-
Myocardial hypertrophy is an independent risk factor for cardiac events. Mitogen-activated protein kinases (MAPK), including extracellular signal-regulated kinases, C-jun N-terminal kinases and P38-MAPK, are the common intracellular pathway of transducing hypertrophic signs. All three MAPK subfamilies play an important role in development of myocardial hypertrophy.
8.Changes of DNA content in the fibroblasts of narrow pedicled subdermal vascular network flap during its surviving
Chinese Journal of Medical Aesthetics and Cosmetology 2002;0(01):-
Objective To study the dynamic changes of DNA content of the fibroblasts in narrow pedicle subdermal vascular network flap (SVNP) during their surviving. Methods Eighteen pieces of surviving skin in pig back with size of 16 cm?8 cm and pedicle wideness of 4 cm were stained with acridine orange, and their DNA contents were measured with the adherent cell analysis and sorting cytometer 570. The tissue samples were taken at 3, 4 ,5 ,and 7 days after operation from different parts of the flap.Results The DNA content of fibroblast in the proximal part of the flap was slightly changed, those in the middle portion increased from 3rd to 5th day and became normal at 7th day, and in the distal portion progressively increased after operation. The results suggested that the transitional part of the flap and skin graft in the middle portion was most active in function and metabolism, and well survived, but the distal portion of the graft was poor in surviving and had a long repairing period. These indicated that local tissue hypoxia stimulated proliferation of fibroblasts and synthesis of the DNA in a short time, but as time wert by, the proliferative speed and DNA synthesis in the individual cell were heterogeneous, probably because of the degeneration or necrosis of some epidermal cells in the graft. Conclusion The wideness and length of the pedicle as well as its vascular anastomoses should be readjusted to promote the blood circulation of the distal skin graft tissues.

AIM To test the hypothesis that intravenous liposomal prostaglandin E 1 (Lipo PGE 1) would attenuate reperfusion injury in a rabbit ischemia reperfusion model. METHODS Twenty four open chest rabbits were randomized to receive a 10 minute intravenous infusion of either liposome diluent (placebo), free PGE 1 (2 ?g?kg -1 ), or Lipo PGE 1(2 ?g?kg -1 PGE 1) after 60 minutes of left anterior desending (LAD) ligation just before reperfusion. Carotid arterial pressure and electrocardiogram were monitored and recorded continously throughout the whole experiment. After 2 hours reperfusion, infarct size and region at risk were measured by postmortem dual dyes with triphenyl tetrazolium chloride (TTC) and Evans blue. Myocardial leukocyte infiltration by myeloperoxidase (MPO) assay was performed. RESULTS Infarct size as a ratio of weight of infarcted tissue to weight of region at risk (MI/RISK) was significantly reduced with Lipo PGE 1 32.20%?4.70% compared with PGE 1 42.09%?6.93% or placebo 44.57%?5.46% ( P
