Objective To investigate the effect of sodium ozagrel injection on hemorheology, endothelin (ET) and nitrogen monoxidum (NO) of patients with non-ST segment elevation myocardial infarction (NSEMI). Methods A total of 81 NSEMI patients were divided randomly into two groups: control group and experimental group. Isosorbide mononitrate, low molecular heparin and simvastatin were administered in the control group while sodium ozagrel was added to the experimental group apart from the above-mentioned drugs. The clinical effect of sodium ozagrel was observed. The changes in the indexes of hemorheology, ET and NO were analyzed. Results The clinical effect was significantly better in the experimental group than in the control group (P<0.05). The level of ET was obviously lower after treatment than that in the experimental group and the control group before treatment (P<0.05). The level of NO was obviously higher after treatment than that in the experimental group and the control group before treatment (P<0.05). The changes of ET and NO in the experimental group post-treatment were more significant than those in the control group after-treatment (P<0.05). The level of hemorheology index after treatment was lower than that before treatment in the experimental group (P<0.05). High-shear rate of whole blood viscosity, platelet adherence rate, and fibrin as hemorheology indexes were lower after-treatment than those pretherapy in the control group (P<0.05). Conclusion Sodium ozagrel injection could affect hemorheology,ET and NO of patients with non-ST segment elevation myocardial infarction. Thefore, the therapeutic efficacy can be better if sodium ozagrel is added to the conventional therapy.

Objective To investigate the therapeutic value of Shuxuetong injection in patients with acute coronary syndrome(ACS).Methods 89 ACS patients were divided randomly into two groups: control group(n =44) and experimental group(n=45).The conventional therapy was used in the control group while Shuxuetong was added in the experimental group.The course of treatment was two weeks.Thromboxane B2(TXB2) and 6-keto-prosta-glandin F1a (6-K-PGF1a) were detected by radio-immunity before and after therapy.Homocysteine were tested by corpuscle enzyme linked immunosorbent assay.Results TXB2 was obviously lower in the experimental group [(554.2±303.2) ng/L] and the control group [(737.2±299.3 ) ng/L ] after treatment than that before treatment (P<0.05).Homocysteine was obviously lower in the experimental group [(10.42±2.99 )μmol/L ] and the control group [(16.39±2.29) μmol/L ] after treatment than that before treatment (P < 0.05 ).6-K-PGF1a was obviously higher in the experimental group[(328.4±99.6) ng/L] and the control group[ (234.5±96.2) ng/L] after treat-ment than that before treatment (P<0.05).TXB2 and homoeysteine in the experimental group were obviously lower than those in the control group after treatment(P<0.05). 6-K-PGF1 a in the experimental group was obviously high-er than those in the control group after treatment (P<0.05).Conclusion Shuxuetong injection could degrade the level of TXB2 and HCY, increase the level of PGF1 a and improve the balance of TXB2/PGF1a, so Shuxuetong is ef-fective in treating acute coronary syndrome.

Objective To investigate the clinical results of resection of periacetabular tumors and reconstruction with fibular autograft. Methods Eight patients with tumors around acetabular were treated surgically in Tongji Hospital between January 1999 and April 2003. The series comprised 5 males and 3 females, with an average age of 39.6 years old (range, 21-65 years old). One patient was diagnosed with osteosarcoma, 2 with chondrosarcoma, 3 with metastatic bone tumor, 1 with giant cell tumor(GCT), and 1 with aneurysmoid bone cyst. There were ⅠB in one patient, ⅡB in 3 patients according to Enneking surgical staging in four primary malignant tumors patients. The tumors involved the zones Ⅱ of Enneking classification in 5 patients, the zonesⅠand Ⅱin 3 patients. All the 8 patients with periacetabular tumors underwent resection and reconstruction with fibular autograft(including 3 cases of a free vascularized fibular graft). Functional results were evaluated according to the system of the Musculoskeletal Tumor Society. Results Bony union occurred 15.2 weeks (range 14-16 weeks) in 5 patients reconstructed with non-vascularized fibular graft and 13.6 weeks (range 12-15 weeks) in 3 patients reconstructed with vascularized fibular graft after the initial surgery. Five of them were followed up ranged from 14 to 42 months (mean 28 months). There were continuously disease-free without complications during follow-up. At the final followup, the average functional score was 22 (range 18-27) according to the system of the Musculoskeletal Tumor Society. The good and excellent rate of functional results was 100%. Conclusion Tumor resection and reconstruction by fibular autograft is an effective treatment for patients with periacetabular tumors. Satisfactory postoperative function was obtained, and relief of pain and walking independently could be achieved with a high level of patient satisfaction.
