Objective To compare the value of intrarectal filling with water and filling in rubber sheath with water in endoluminal uhrasonography for preoperative staging of rectal tumors. Methods 215 cases of rectal tumors were divided into two groups. 120 cases using the method of filling in rubber sheath with water and 95 cases using intrarectal filling with water were diagnosed with uhrasonography. The results were compared with corresponding pathologic results for the judgment of their accuracy. Results The accuracy for the diagnosis of infiltration depth was 60.0 % in the first group and was 73.7 % in the second. The difference was statistically significant (P <0.05). The accuracy for diagnosis of metastases of perirectal lymph nodes was 82.5 % in the first group and was 80.0 % in the second. The difference has no statistical significance (P >0.50). Conclusion Intrarectai filling with water is better than filling in rubber sheath with water in the diagnosis of infiltration depth of rectal tumors, while there is no difference in the diagnosis of metastasis of perirectal lymph nodes.

Endostatin is a potent, endogenous inhibitor of angiogenesis, which corresponds to the C-terminal fragment of collagen ⅩⅧ. The human endostatin gene was amplified from a human fetal liver cDNA library by means of PCR and was cloned into pPIC9K vector. Soluble endostatin was superexpressed in Pichia pastoris (50.5mg/L) . The recombinant protein was purified by cation exchange chromatography with the final yield of more than 95%. Western blotting analysis showed positive immunoreactivity to the expressed product. Recombinant endostatin was able to suppress the angiogenesis on the CAMs. Also, the endostatin inhibited specifically of the migration of HMECs stimulated by bFGF, with EC50 being about 0.4 ?g/ml.

Objective To study the relationship between viral infection and chronic obstructive pulmonary disease (COPD),and the effect of viral infections on the changes of Th1/Th2 in COPD patients. Methods The se-ra from 81 patients with acute exacerbations of COPD,25 patients with stable COPD and 22 healthy subjects were tested for specific IgM of respiratary syncytial virus(RSV) ,herpes simplex virus type 1 (HSV-1), parainfluenza vi-rus (PIV), adenovirus (ADV) and cytomegalovirus (CMV) by indirect enzyme-linked immunosorbent assay (ELISA). Supernatant INF-γ and IL-4 cultured with PHA were determined. Results The positive rates of IgM in patients with acute exacerbations of COPD compared with those in patients with stable COPD and healthy subjects were significantly different(P <0.001 ). The level of INF-γ, and IL-4 in patients with acute exacerbations of COPD and stable COPD compared with normal control group;the level of INF-γ (242±43) and the of IL-4(42±9) in pa-tients with acute exacerbations of COPD was not significantly different as compared with the level of INF-γ( 198±32) and the level of IL-4(56±11 ) in patients with stable COPD (P<0.05), but the level of INF-γ was increased (90±18)and IL-4 was decreased (141±24) in control group (P<0.05). Compared with those in IgM negative group, the levels of INF-γ were significantly higher and the levels of IL-4 were significantly lowerIL-4 in lgM positive group( P<0.01 ). Conclusion Virus infection is a rather important factor in acute exacerbations of COPD, and COPD is characterized by a predominance of Th1-type response,and there is more significant Th1 response predomi-nance in COPD with virus infection.
