Objective To explore the application value of superior mesenteric vein-caval-right atrium Y shape shunt (abbr.SMV-CV-RA Y shape shunt) as a new approach for treatment of mixed pattern Budd-Chiari syndrome (B-CS).Methods The clinical data of 101 cases of mixed pattern B-CS patients were evaluated for the curative effect.Of the 101 patients,62 were treated with superior ruesenteric vein-caval-right atrium Y shape shunt,26 with splenic vein-caval shunt and 13 with superior mesenteric vein-caval shunt using artificial vascular graft.Results Compared with the plastocyte count of patients receiving splenic vein-caval shunt and superior mesenteric vein-caval shunt,the plastocyte count of 62 cases undergoing SMV-CV-RA shunt increased obviously after operation (P＜0.05).The portal vein pressure of patients with SMV-CV-RA shunt decreased significantly (P＜0.05),but the pressure of patients in splenic vein-caval shunt group and superior mesenteric vein-caval shunt group deceased slightly (P＞0.05).The incidence of hepatic encephalopathy in one year after operation was not significantly different among the 3 groups (P＞0.05).The incidence was 3.2%(2/62),0% (0/26),0% (0/13),respectively.The recanalization rate of artificial vascular graft was 95.2%(59/62),69.2%(18/25),38.4%(5/13),respectively in SMV-CV-RA shunt group,splenic vein-caval shunt group and superior mesenteric vein-caval shunt group.The recanalization rate of artificial vascular graft in SMV-CV-RA shunt group was increased significantly (P＜0.05).Conclusion Compared with splenic vein-caval shunt and superior mesenteric vein-caval shunt,the SMV-CV-RA Y shape shunt can get satisfactory effeet in curing massive hemorrhage of gastrointestinal tract for cutting down the pressure of portal vein and inferior vena.Otherwise,the shunt could eliminate hypersplenia of patients.The splenic vein-caval shunt and superior mesenteric vein-caval shunt are not effective in curing the mixed pattern B-CS.

Objective To discuss the types,pathogenesis and treatment of early cardiac arrhyth-mias in infants after open heart surgery with congenital heart diseases. Methods 992 infants after open heart surgeries were divided into control group and arrhythmia group. Another junctionalectopictachycardia ( JET)group was separated from arrhythmia group. Various preoperative and postoperative data were com-pared. Results 197 infants suffered from cardiac arrhythmia within 3 days right after open heart surger-ies. After exactly the same surgery procedures,JET group was significantly different with control group in aortic cross-clamp time,cardiopulmonary bypass time and stay in CICU(p<0. 05). As for time of ventila-tion,no significant difference was found between the two groups. Conclusion Early diagnosis and treat-ment of cardiac arrhythmia can not only improve the success rate of open heart surgery,but also promote early recovery.

Results The positive rate of CD90 (63.89％,23/36),IGF1R (52.78％,19/36) in hepatocellular carcinoma significantly increased (P ＜ 0.05 ); The positive rate of CD90 was higher in UICC Ⅲ - Ⅳ stage group (79.17％ ) than in UICC stage Ⅰ - Ⅱ group (33.33％,P ＜0.05) ;The positive rate of CD90 was higher in low differentiated group (76.92％ ) than in well-differentiated group (56.52％,P ＜0.05).The positive rate of IGF1R was higher in UICC Ⅲ - Ⅳ stage group (70.83％ ) than in UICC stage Ⅰ - Ⅱ group ( 16.67％,P ＜ 0.05 ). The positive rate of IGF1R was higher in low differentiated group (84.62％) than in well-differentiated group (37.38％,P ＜ 0.05 ).The expression of IGF1R was positively correlated with that of CD90 (P ＜ 0.05 ).The median survival of CD90+ patients (85 days) was shorter than CD90- patients ( 505 days ) ( P ＜ 0.05 ).The median survival of IGF1 R + patients (100 days) was shorter than IGF1 R- patients (408 days,P ＜ 0.05). Conclusions CD90 or IGF1R expression correlates positively with the progression of HCC.

Objective To observe the influence of hIL-10-MSCs on apoptosis of rats subject to discordant liver xenotransplantation. Methods The model of guinea pig to rat discordant liver xenotransplantation was set up. The orthotopic liver transplantation model was established by using modified two-cuff technique. Following groups were designed: control group, MSCs group and hIL-10MSCs group. Before and after operation, the recipients in control group were injected with normal sodium (2 ml) and decaesadril (0.5 ml) ;Those in MSCs group were injected with MSCs (4.0× 106/ml)and decaesadril (0.5 ml); Those in hIL-10-MSCs group were injected with hIL-10-MSCs (4.0 × 106/ ml)and decaesadril (0.5 ml). Twelve h after operation, the livers of recipient were observed by HE staining and electron microscope, and apoptosis of the livers was detected by using TUNEL. The expression levels of hIL-10, caspase-3, Fas and FasL were assayed by Western blot or immunohistochemistry. Results As compared with control group and MSCs group, the pathological changes was alleviated, the expression of IL-10 was significantly increased, the expression of FasL was significantly reduced in hIL-10-MSCs group. The positive area size of Fas and Caspase-3 in hIL-10MSCs group was 11.5 % and 25.1 %, respectively, significantly smaller than those in control group (35.3 % and 70.8 % respectively, P＜0.05. Apoptosis index in hIL-10-MSCs group was 32.5 %,which was significantly lower than in control group (74.1%) and MSCs group (50. 3 % ). ConclusionhIL-10-MSCs can notably decrease apoptosis of the transplanted liver probably by inhibiting theexpression of Fas/FasL.

Objective To observe the influence of hIL-10-MSCs on rejection of rat discordant liver xenotransplantation. Methods The model of cavia to rat discordant liver xenotransplantation was established. The rats were randomized into the control group, MSCs group, and hIL-10-MSCs group.The survival time and liver function of each recipient were observed and expression levels of E-Selectin, LFA-1, VCAM-1, and NF-κB determined by RT-PCR and ELISA 24 h after transplantation.Results The survival time was prolonged, liver function improved, and expressions levels of E-Selectin, LFA-1, VCAM-1 and NF-κB were significantly decreased in the hIL-10-MSCs group (P＜0.05).Conclusion hIL-10-MSCs are able to protect transplanted liver and decrease the expression of E-Selectin, LFA-1, VCAM-1, and NF-κB in the liver.

Objective To observe the effects of hIL-10-MSCs on heterologous T cell prolifera-tion. Methods hlL-10 was cloned by RT-PCR and then hIL-10/pLOX-cwGFPs was construct. The lentivirus was transfected into cavy MSCs and cell culture supernatant was tested for IL-10 protein by ELISA assay. The effects of hIL-10-MSCs on heterologous T cell proliferation were determined by CCK-8. The effect of peripheral blood mononuclearcell secretion IFN-γ was tested by EIASA. Results hIL-10/pLOX-cwGFP were constructed successfully and hIL-10-MSCs cell culture supernatant of IL-10 protein were increased obviously, hIL-10-MSCs could inhibit heterologous T cell proliferation sig-nificantly(P<0.05) but could not induce T cell proliferation (P<0.05). Adding IL-2 could reverse this inhibition(P<0.05), hIL-10-MSCs cell culture supernatant could inhibit peripheral blood mono-nuclearcell secretion IFN-γ. Conclusion hIL-10-MSCs may play an important role in significant im-munosuppression of heterologous T cell proliferation and suppression of secretion IFN-γ by peripheral blood mononuclear cells.

AIM:To investigate whether renal function damage could be induced by acute lung injury(ALI)in aging rats. METHODS: 40 Wistar male rats were used for reproducing aging animal model. Aging rats were randomly divided into aging control; ALI group (Lipopolysaccharide, LPS, 5 mg/kg body weight, iv) and LPS group (same dosage LPS, intraventricle of left heart injection). The samples (blood, lung and kidney ) were collected at 2 or 6 hours after LPS or normal saline administration. RESULTS:Compared with aging control, in ALI group, creatinine (Cr) and urea nitrogen (BUN) contents in blood were increased significantly (all P
