However, the potential risk associated with allogeneic blood transfusion has heightened interest in the use of autologous blood transfusion. In the present study, the serum concentrations of neopterin, interferon-gamma （IFN-γ）, T lymphocyte subsets （CD3^＋, CD4^＋, CD8^＋, CD4^＋/CD8^＋） and a possible association between these variables were investigated. The purpose was to further evaluate the effect of autologous versus allogeneic blood transfusion on immunological status in patients undergoing surgery for gastric cancer. Methods： Sixty ASA Ⅰ～Ⅱ（American Society of Anesthesiologists） patients undergoing elective radical resection for stomach cancer were randomly allocated to receive either allogeneic blood transfusion （n=30） or autologous blood transfusion （n=30）. Serum concentrations of the neopterin, IFN-γ and T lymphocyte subsets in the recipients were measured before induction of anesthesia, after operation, and on the 5th postoperative day. Results： Both two groups, serum neopterin, IFN-γ, percentages of T-cell subsets （CD3^＋, CD4^＋）, and CD4^＋/CD8^＋ ratio had significantly decreased after operation, but decreased more significantly in group H （receiving allogeneic blood transfusion） than those in group A （receiving autologous whole blood transfusion） （P〈0.05）. On the 5th postoperative day,serum neopterin, IFN-γ, CD3^＋, CD4^＋ T-cells, and CD4^＋/CD8^＋ ratio returned to the baseline values in group A. In contrast, the above remain decreasing in group H, where there were no significant relations between serum neopterin and IFN-γ. Conclusion：Perioperative surgical trauma and stress have an immunosuppressive impact on gastric cancer patients. Allogeneic blood transfusion exacerbates the impaired immune response. Autologous blood transfusion might be significantly beneficial for immune-compromised patients in the perioperative period, clearly showing its superiority over allogeneic blood transfusion.展开更多

Methods Two hundred and fifteen women with ectopic pregnancy underwent operative laparoscopy. These patients were divided into two groups. The study group included 21 patients with shock and intraperitoneal hemorrhage more than 1000 mL, and control group included 194 patients, hemodynamically stable, with blood loss less than 1000 mL. Clinical data of perio-perative periods in two groups were retrospectively analyzed. Results All patients were tubal pregnancies. The occurrence rate of tubal rupture was higher in study group than in control group (80.95% vs. 15.98%, P < 0.001). Intraabdominal blood loss was significantly higher in study group than in control group (1900 mL vs. 300 mL, P < 0.001), and autologous blood transfusions were given to 95.24% and 9.3% of patients in study and control group, respectively (P < 0.001). Laparoscopic salpingectomy was performed on 85.7 % and 50.5% of patients in study and control group (P < 0.001). The operative time was somewhat longer in study group than that in control group (60 minutes vs. 45 minutes), but with no significant difference. All patients had no perioperative complications. Conclusion Operative laparoscopy in patients with hopovolemic shock can be safely and effectively performed by experi-enced laparoscopists with the aid of optimal anesthesia, advanced cardiovascular monitoring, and autologous blood transfusion.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
