METHODS: A systematic review of the literature in the electronic database Medline and the Clinic Trials Registry Database was performed. Literature that did not fit our study were excluded. Patients in the reviewed studies were divided into two groups; one group used aprotinin (aprotinin group) while the other did not (control group). The data in the literature that fit our requirements were recorded. Weighted mean differences (WMD) in the requirements for blood products between the aprotinin group and the control group were tested using a fixed effect model. A Z test was performed to examine their reliability; the Fleiss method of fixed effect model was used to analyze data on postoperative events, and odds ratios (ORs) were tested and merged. RESULTS: Seven citations were examined in our study. Among them, a requirement for blood products was reported in 4 studies including 321 patients, while postoperative events were reported in 5 studies including 477 patients. The requirement for red blood cells and fresh frozen plasma in the aprotinin group was statistically lower than that in the control group (WMD=-1.80 units, 95% CI,-3.38 to-0.22; WMD=-3.99 units, 95% CI,-6.47 to-1.50, respectively). However, no significant difference was indicated in the incidence of laparotomy for bleeding, thrombotic events and mortality between the two groups. Analysis on blood loss, anaphylactic reactions and renal function was not performed in this study due to a lack of sufficient information.CONCLUSION: Aprotinin can reduce the intraoperative requirement for blood products in OLT, and has no significant effect on the incidence of laparotomy for bleeding, thrombotic events and mortality.展开更多

METHODS: The proportion of patients who received HT was compared between two groups determined by the time of AT introduction; period A (1991-1994, n = 93) and period B (1995-2000, n = 201). Multivariate logistic regression analysis was performed in order to identify independent significant predictors of the need for HT. We also investigated the impact of AT and HT on long-term postoperative outcome after curative surgery for HCC. RESULTS: The proportion of patients with HT was significantly lower in period B than period A (18.9% vs 60.2%, P < 0.0001). Multivariate logistic regression analysis identified AT administration as a significant independent predictor of the need for HT (P < 0.0001). Disease-free survival in patients with AT was comparable to that without any transfusion. Multivariate analysis identified HT administration as an independent significant factor for poorer disease-free survival (P = 0.0380). CONCLUSION: AT administration significantly decreased the need for HT. Considering the postoperative survival disadvantage of HT, AT administration could improve the long-term outcome of HCC patients.展开更多

Methods: Serum TTV DNA was tested in 69 hemodialysis patients from our hospital by nested-PCR using primers from a conservative region of TTV genenome, gene sequence analysis and detection of hepatitis C virus antibody (anti-HCV) and the levels of alanine transaminase (ALT) were determined simultaneously. Results: The overall prevalence of TTV viremia was 27.5%. The PCR-amplified gene fragment from one patient was sequenced, and its Sequence homologies with TTV-UHI, TTV-TA278, TTVCHN1 and TTVCHN2 ranged from 89% to 100%, and its deduced amino acid sequence homologies with these 4 isolates ranged from 87% to 100%. There was no significant difference in 1TV prevalence between anti-UCV positive and negative patients (P＞0.05). No significant elevation of ALT is found in all patients. Conclusion: High prevalence of TTV infection is found among hemodialysis patients, and TTV infection has no significant association with HCV infection or elevation of ALT.展开更多

This study retrospectively analyzed the therapeutic effect and shared our experience. The average amount of blood transfused back was 662.41 ml ± 269.15 ml. None of the patients developed transfusion reaction and were all discharged uneventfully. Thoracoscopic surgery combined with autologous blood transfusion is effective in the rescue of patients with progressive hemothorax and hemorrhagic shock. When corresponding indications are well managed, treatment for these patients is quicker, safer, and more effective.展开更多
