Objective To study the feasibility of preoperative acute hypervolemic hemodilution for decreasing perioperative blood use. Methods Thirty two patients(ASAI-II) undergoing spinal surgery were randomized into AHH group and control group. After anesthesia 6% HES(200/0.5) was given through internal jugular vein for AHH. The blood volume was increased by about 25%. During the operation, blood loss was replaced by HES in equal volume. Blood was transfused when the Hct dropped below 25%. The HR, MAP, CVP, SPO2, Hb, Hct., Plt, FIB, APTT, PT, amount of blood loss, blood transfused and urine output, volume of drainage 24h after operation and VAS score (0 means no effect, 10 means maximal effect) were observed before AHH, at the end of AHH, at the end of operation, and 24h after the operation. Blood volume expansion was calculated. Results (1) HR increased significantly in both groups(P

Objective To analyse the plasma glucose change in the patients with severe acute respiratory syndrome (SARS) and to discuss its possible mechanism. Methods The clinical data of 61 cases with SARS in Tianjin were retrospectively analysed. Results Plasma glucose level increased in 26 cases with SARS, among them, 2 cases suffered from diabetes before SARS onset, 24 cases were diagnosed as the secondary diabetes whose blood glucose level recovered normal after SARS were cured, except 4 cases who were dead. All of the 61 cases were treated with glucocorticoids. If the patients were grouped by the dose of methylprednisolone they received, 9 out of 14 cases with large dose, 14 out of 26 cases with middle dose and 1 out of 21 cases with small dose were led to secondary diabetes. There was significant difference in the incidence of the secondary diabetes between the small dose group and middle/large dose groups (P

Objective To evaluate mortality associated with simultaneous bilateral or staged bilateral TKA, and better understand the risks involved in the simultaneous versus staged bilateral procedures.Methods A systematic review was conducted, following an a priori protocol, according to the methods recommended by the Cochrane Musculoskeletal Group in the Cochrane Collaboration. Eligible studies were identified in PubMed (1990-2010), OVID MEDLINE (1990-2010), and the Cochrane library, concerning postoperative complications of bilateral or staged bilateral total knee arthroplasty. All of the English-language abstracts were obtained, and retrieval words including bilateral total knee arthroplasty, staged total knee arthroplasty, and total knee arthroplasty, etc. An extensive analysis was then performed to identify articles fulfilling the inclusion criteria for the study. The details of the reported data were extracted and evaluated by two reviewers independently. Data analyses were conducted with Stata 10.0. Results Six studies met our inclusion criteria for review. The combined results showed that the prevalence of mortality[OR=2.925, 95% CI (2.352, 3.638)], mortality 30 days postoperatively[OR=5.078, 95% CI (2.192, 1 1.763)]and mortality in 70 years or older patients[OR=4.087, 95% CI (1.947, 8.582)]were statistically higher in the population that had undergone simultaneous TKA compared with staged TKA. Conclusion Compared with staged bilateral TKA, simultaneous bilateral TKA might carries a higher potential risk of postoperative mortality. Patients should be aware of this information when deciding whether to proceed with simultaneous bilateral TKA. Further well-designed and large-scale randomized controlled trials are required to confirm these findings.

Objective To establish a big animal model of secondary infection of acute necrotizing pancreatitis (ANP). Methods Thirty young pigs were allocated to experiment group ( n = 20 ) or control group (n = 10). The ANP model was induced by retrograde injection of a mixture solution of 5% sodium taurocholate and 5% trypsin (0. 5 ml/kg body weight) into the main pancreatic duct and ligation of the proximal end of the main pancreatic duct, and then the second step was injecting 3 ~ 4 ml living Escherichia coli (E coli) suspension (108/ml) to the necrotic area of the pancreas by fine needle aspiration technique under CT guidance in the experiment group, and by injecting 3 ~ 4 ml inactivated E coli in the control group using the same method. Multi-slice spiral CT dynamic enhanced scan was performed in both groups 1 day and 2 or 3 days after ANP modeling and 5 days after bacterial injection to calculate the CTSI score. Serum amylase, blood WBC count and blood bacterial culture was performed in both groups. 5 days later, the animals were scarified to observe the infected or necrosis foci, and perform smear, bacterial culture and pathologic examinations of the tissue around the infected or necrosis foci. Results The ANP secondary infection model was successfully established in 16 of the 20 animals in the study group, with a success rate of the 80.0% (16/20). There were 17 foci where the positive rate of bacterial culture was 100% (17/17 foci), and the success rate of blood bacterial culture was 68.8%(11/16). In the control group, the ANP model was established successfully in 7 of 10 animals (70%), except for one case of contamination, only one foci was identified;the positive rate of bacterial culture and the success rate of b|ood bacterial culture was 14.3% (1/7). Serum amylase and white blood WBC count increased with similar trends, WBC count in the study group was significantly higher than that in the control group (P<0.01). The mean CT severity index(CTSI) was all ≥4 in beth groups, indicating the severity was moderate to severe. Conclusions A stable and reliable model of secondary infection of ANP in big could be established satisfactorily by injecting active E. coli into the pancreatic necrosis tissue under CT guidance, which helps further pathogenic mechanism studies and clinical studies, especially imaging studies.
