Objective To review the surgical results of 28 cases of endecardial cushion defect combined with double-ori-rice mitral valve. Methods Of 860 consecutive patients with endocardial cushion defect, double-orifice mitral valve was iden-tiffed in 28 patients (3.26% ) form October 1996 to November 2007. Intracardiac deformities were corrected simultaneously during the operation. Preoperative mitral valve function, surgical procedures and incidence of pestoperative mitral valve dys-function were reviewed and compared between patients with total endecardial cushion defect ( group Ⅰ, n = 11 ) and partial en-docardial cushion defect ( group Ⅱ, n = 17). Results There were 4 operative deaths in group Ⅰ caused by severe pulmonary inflammation in 3 cases and low cardiac output in 1 case. Two cases were identified as severe mitral valve dysfunction or steao-sis in reoperaticu or autopsy. There was no later death. Mitral valve function is not eatisfactory in group Ⅱ as compared with group Ⅰ in 3 to 89 months of follow-up( averaging 33 months). Conclusion Double-orifice mitral valve is a high risk factor for operative death in total endocardial cushion defect and the longer term results of partial endocardial cushion defect combined with double-orifice mitral valve is not satisfactory.

Objective To observe the influence of Sishen Pill on the NF-κB p65 mRNA and protein expressions of colonic mucosa in rats with experimental ulcerative colitis (UC), and identify its underlying mechanism of action. Methods The experimental rats were divided into blank group, model group, Sishen Pill group and SASP group. The models were prepared by TNBS/ethanol enema. Sishen Pill group was intragastrically administrated by Sishen Pill extract 5 g/kg, SASP group by SASP 0.3 g/kg, and blank group and model group by equal volume of normal saline. The morphological injury of colonic mucosa was observed and scored with the naked eyes, and NF-κB p65 gene and protein expression were detected by RT-PCR and immunohistochemical method. Results Inflammation and ulceration on the colonic mucous membrane were found in the model group by naked eyes, and had significant difference with the blank group (P<0.05). The relative expression amount of NF-κB p65 gene and protein of colonic tissues were increased in the model group compared with the blank group (P<0.01). Compared with the model group, the relative expression amount of NF-κB p65 gene and protein in Sishen Pill group were decreased (P<0.05, P<0.01). Conclusion Sishen Pill has effect for treating UC, which is probably related to the activation of NF-κB signal transduction pathway.

Objective To observe the effect of Sishen Pill on ICAM-1 mRNA and protein expression of colonic mucosa in rats with ulcerative colitis (UC), and identify its mechanism. Methods Taolly 40 SPF Wistar rats were randomly divided into blank group, model group, Pill group and SASP group. Except the blank group, UC model was prepared with TNBS/ethanol enema. Pill group was given Sishen Pill 5 g/kg, and SASP group was given SASP 0.3 g/kg by gavage, blank group and model group was given the same volume physiological saline for three weeks. Morphological injury of colonic mucosa was observed and scored. ICAM-1 gene and protein expression were detected by RT-PCR and immunohistochemical method. Results Inflammation and ulceration were found on the colonic mucous membrane of rats in the model group. The expression of ICAM-1 gene and protein of colonic tissues of rats in the model group increased compared with that of the blank group (P<0.01). Compared with the model group, the expression of ICAM-1 in Pill group decreased (P<0.05, P<0.01). Conclusion Sishen Pill can decrease the expression of ICAM-1 mRNA and ICAM-1 protein, inhibit the infiltration of inflammation cells, prevent and reduce colon tissue damage, and play a vital role in the treatment of UC.

BACKGROUND:Platelet rich plasma contains various growth factors, such as platelet-derived growth factor, metastatic growth factor, insulin-like growth factor, epidermal growth factor as wel as vascular endothelial growth factor. Therefore, it can directly or indirectly promote cel differentiation and proliferation in different stages of bone regeneration.
OBJECTIVE:To study the effects of coral bone with platelet rich plasma in the repair of mandibular defects.
METHODS: Totaly 24 New Zealand white rabbits were randomly divided into three groups (n=8 per group) including test group, control group and blank control group. Coral bone with autologous platelet rich plasma, coral bone or nothing was implanted, respectively, after establishing unilateral mandibular defect models. The defects were evaluated by imaging observation and bone his-tomorphometric analysis at 2, 4, 8, 12 weeks after surgery.
RESULTS AND CONCLUSION:At 12 weeks after surgery, by imaging observation, density of the defect increased in the blank control group, which was lower than that of the normal bone; the bone density in the test group was higher than that in the control group, both of which were similar with the normal bone. Besides, the materials were closely combined with the new tissues. By bone his-tomorphometric analysis, area of the new bone in the test group was significantly larger than that in the control and blank control group (P< 0.05). In conclusion, coral bone with platelet rich plasma has good biocompatibility and bone conductivity, which can induce bone regeneration to promote defect repair.

Aim: To explore the relationship between structure and immunological activity of marine polysaccha-ride YCP,the physicochemical property and immunological activity of the YCP-derived fragment were studied.Methods: YCP was hydrolyzed by α-amylase from human saliva.The hydrolysate was purified to obtain an polysaccharide fragment by gel filtration chromatography.The physicochemical properties of this YCP-derived fragment was characterized by HPLC,FT-IR and TLC.In addition,changes of phagocytic activity,production of reactive nitrogen and macrophage binding were investigated.Results: The relative molecular weight of YCP-de-rived fragment was approximately 6.6 × 10~3.The monosaccharide composition and FT-IR of the YCP-derived frag-ment were identical to YCP.No significant effect of the YCP-derived fragment on NO production and murine mac-rophage phagocyte were observed.And this fragment was not able to compete the binding between YCP and mac-rophages.Conclusion: The remarkable decrease of immunological activity of YCP-derived fragments degraded byα-amylase of human saliva suggests that the complete structure and high molecule weight of YCP are essential for its immuno-modulatory activity.
