Objective To investigate the clinical characteristics, diagnosis and treatment of acute mesenteric venous thrombosis(MVT) in the elderly. Methods The clinical features, diagnosis, treatments and prognosis of 10 aged cases with acute MVT were retrospectively analyzed. Results The chief complaints of the 10 cases were different degrees of abdominal pain, which not paralleled with abdominal signs. The accompanying symptoms were nausea, vomiting and bloody stools and so on. All of these patients were misdiagnosised as pancreatitis, appendicitis or intestinal obstruction and so on. diagnosis of two cases was confirmed by ultrasound, 8 by CT. At the same time, 2 cases underwent angiography examination. Of the 8 cases who underwent operation, 5 cases were cured, 3 cases died (1 died of toxic shock and 2 died of multiple organ failure ). Two cases underwent conservative intervention thrombolysis. Conclusions It is essential to improve the knowledge of acute MVT,especially its intricate clinical characteristics, high rates of misdiagnosis and mortality. Early proper diagnosis is crucial. The main treatment is operation and conservative intervention thrombolysis can be performed in the patients whose bowel has not necrosed yet.

OBJECTIVETo summarize the clinical experience about surgical treatment of aortic dissection.
METHODSThe clinical data of 51 patients with aortic dissection admitted from December 2004 to December 2006 were analyzed retrospectively. There were 35 male and 16 female patients with a mean age of 55.7 years (ranged from 18 to 83-years-old). Twenty-seven patients of type I was performed under deep hypothermic circulatory arrest and selected cerebral perfusion with stent-graft which was implanted into the descending aorta through aorta arch. Five patients of type II was performed including Bentall operation in 3 patients, Wheat operation in 1 patient, ascending aorta replacement in 1 patient. Nineteen patients of type III was performed with stent-graft which was implanted into the descending aorta through aorta arch under deep hypothermic circulatory arrest.
RESULTSThe time of cardiopulmonary bypass (CPB) in type I patients was 250 to 290 min with an average of (274 +/- 53) min, and the arrest time was 40 to 59 min with an average of (53 +/- 14) min. CPB time of type II patients was 130 to 159 min with an average of (146 +/- 43) min, and the cross clamp time was 60 to 79 min with an average of (66 +/- 15) min. CPB time of type III patients was 240 to 280 min with an average of (260 +/- 28) min, and the arrest time was 20 to 27 min with an average of (24 +/- 3) min. The mean hemorrhage volume of the entire group was (500 +/- 250) ml. The mean ICU retention time was (5.0 +/- 1.5) d and the length of stay was (15.0 +/- 2.5) d. Three patients died during perioperative period. Two patients appeared cerebrovascular accident after operation. One patient appeared descending aorta dilation in the follow-up of 2 to 21 months.
CONCLUSIONDifferent clinical manifestations and treatment should be selected according to the different condition of aortic dissection aneurysm.

Objective To review the techniques used in biliary reconstruction for adult-adult living donor liver transplantation using a right lobe graft. Methods The clinical data of 21 pairs of donor and recipient who underwent right lobe living donor liver transplantation from April 2007 to May 2009 at Beijing Youan Hospital were analyzed retrospectively. Biliary anastomoses consisted of 10 single right hepatic duct to common hepatic duct anastomoses, 5 donor double branched ducts to recipient double branched ducts anastomoses, 5 single anastomoses between a donor double branched duct which had been converted to a single duct by ductoplasty to a single recipient bile duct, and 1 hepaticojejunostomy. A T-tube was inserted through the anterior wall of the common hepatic duct and splinted across the anastomosis in 2 recipients and a Y-tube was used in 1 recipient. Results 4 recipients died during the first post-transplant month. Another recipient received a retransplantation for acute liver necrosis. The remaining recipients were alive. The 1-year survival rate of the recipients was 77.65 %.5 patients developed biliary leakage and 2 patients developed biliary stricture. The 7 biliary complications were treated and cured by further surgical procedures. There was no significant difference in the biliary complications among the three different types of biliary anastomotic groups (x2 = 0. 659,P=0. 719). Conclusion The different types of biliary anastomoses can be used in living donor liver transplantation depending on the situations found in the donors and recipients. Continuous suturing on the posterior wall of the bile duct, interrupted suturing on the anterior wall and microsurgical techniques in biliary reconstruction are effective modalities to minimize biliary complications.

Objective To investigate technical skills on outflow reconstruction in right lobe graft adult-adult living donor liver transplantation for avoiding of venous congestion. Methods The clinical data of 21 donors and recipients who underwent right lobe living donor liver transplantation were analyzed retrospectively. Donor's standard liver volume was between 1150. 1 and 1629. 8 cm3,graft weight was between 585 and 920 g, the ratio of graft volume to recipient's estimated standard liver volume (GV/ESLV) was between 43 % and 67 %, graft-recipient weight ratio (GRWR) was between 0. 82 % and 1.59 %, the ratio of remnant liver volume to donor's standard liver volume(RLV/SLV) was between 32 % and 55 %, all graft macrosteatosis was less than 10 %. For graftwith middle hepatic vein (MHV), a triangle large orifice was made by joining MHV to right hepatic vein (RHV), then anastomosed to recipient' s enlarged orifice of RHV. For graft without MHV, if tributary of MHV>5 mm, autologous or allogenic blood vessel was used as interposition graft to connect to IVC, and if no large MHV tributary, graft RHV was anastomosed to IVC directly. Graft's right portal vein was anastomosed to main trunk of recipient's portal vein, graft's right hepatic artery to recipient's hepatic artery, and graft's right hepatic duct to recipient's right hepatic duct. Results Among the 21 right lobe grafts, 4 right lobe grafts had MHV, 17 right lobe grafts had no MHV.Autologous greater saphenous veins were adopted in 2 cases, cryopreserved iliac arteries were adopted in 5 cases, and RHV was anastomosed directly to IVC in 10 cases. Outflow was all patent in 7 cases having reconstruction of MHV tributaries one month after operation. One-year survival rate was 75 %, 85. 7 % and 70 % respectively in MHV group, MHV tributaries reconstructed group and RHV directly anastomosed to IVC group with the difference being not significance among these three groups (P>0. 05). Biliary complications occurred in 7 cases during the follow-up period. One case developed small-for-size syndrome, which was cured by splenic artery embolization. No severe complication occurred in donors. All donors returned to normal life during a follow-up period of 6 to 31 months. Conclusion If outflow tract was reconstructed properly, right lobe graft without MHV has equivalent clinical outcomes to right lobe graft with MHV. Using of autologous or allogenic blood vessel as interposition vessel graft for right lobe graft without MHV is an effective modality to prevent hepatic congestion and secure functional graft volume to meet recipients metabolic demand.

OBJECTIVETo investigate HIV survival time and it's influencing factors among former commercial blood and plasma donors engaged in unsafe blood donation practices in China.
METHODSHIV/AIDS cases from 8 counties (districts) in 4 provinces confirmed prior to January 24, 2006 related with former commercial blood and plasma donors were selected and data regarding infection, AIDS progression, death, and influencing factors were retrospectively collected.
RESULTSIn 530 cases of HIV infection, 334 (63.0%) cases had developed AIDS, 168 (50.3%) had received antiretroviral therapy (ART), and 152 (29.0%) had died. For the 530 cases, there was an average (10.1 +/- 1.8) years of observation from time of infection. Among 166 AIDS patients not receiving ART, average survival was 9.1 years (95% CI: 9.1 - 9.4), with an 8 year survival rate of 52.0%. Among 168 AIDS patients receiving ART, average survival was 12.1 years (95% CI: 11.9 - 12.3), with a 12-year survival rate of 80.0%. In 3 years of ART, average survival was longer in the treatment group as compared to the no treatment group with a hazard ratio for death of 12.2. Univariate analysis showed a significant difference (P < 0.05) in AIDS patient average survival based on gender, age, location, ART status, and baseline CD(4)(+) T cells count. Results from multivariate COX-regression showed that highly active ant iretroriral therapy (HAART) was the strongest protective factor for prolonging AIDS patients' survival (HR = 13.3, P = 0.00).
CONCLUSIONAlthough there are many factors influencing AIDS patients survival, intervention with HAART is the principle measure to prolong survival and decrease the risk of death.
