0.05).All cases showed normal bone formation. Conclusion:There is no significant influence on tibial growth if cancellous bone harvesting is controlled strictly in two third of total amount from tibial proximal metaphyses.

Objective: To estimate the clinical efficacy of combination of chemotherapy with osteoblast promoting and anti-osteolys-is agents in bone metastatic carcinoma. Methods: Seventy-one patients with bone metastatic carcinoma were divided into 2groups and treated with protocol A or B, respectively. The protocol A was a combination of chemotherapy with osteoblastpromoting and anti-osteolysis agents, the protocol B was a combination of chemotherapy with antiosteolysis agent only. Theefficacies of the 2 protocols were compared and studied. Results:The effect of A was more remarkable than that of B in re-lieving bone pain and enhancing bone repair. No severe adverse effect of these agents was found in therapy. Conclusion: Theclinical efficacy of combination of chemotherapy with osteoblast promoting and anti-osteolysis agents in bone metastatic car-cinoma was definite, the osteoblast promoting agent as an effective adjtmctive agent can be used not only in osteoprosis butalso in bone metastatic carcinoma.

Ammonium perchlorate (AP), mainly used as solid propellants, was reported to interfere with homeostasis via competitive inhibition of iodide uptake. However, detailed mechanisms remain to be elucidated. In this study, AP was administered at 0, 130, 260 and 520 mg/kg every day to 24 male SD rats for 13 weeks. The concentrations of iodine in urine, serum thyroid hormones levels, total iodine, relative iodine and total protein, and malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) activity in thyroid tissues were measured, respectively. Our results showed that high-dose perchlorate induced a significant increase in urinary iodine and serum thyroid stimulating hormone (TSH), with a decrease of total iodine and relative iodine content. Meanwhile, free thyroxine (FT4) was decreased and CAT activity was remarkably increased. Particularly, the CAT activity was increased in a dose-dependent manner. These results suggested that CAT might be enhanced to promote the synthesis of iodine, resulting in elevated urinary iodine level. Furthermore, these findings suggested that iodine in the urine and CAT activity in the thyroid might be used as biomarkers for exposure to AP, associated with thyroid hormone indicators such as TSH, FT4.

Objective: To explore the blood-saving effect of autologous platelet-rich plasma (PRP) back-transfusion in patients with Stanford type A aortic dissection surgery. Methods: A total of 59 consecutive patients who received Stanford type A aortic dissection surgery in our hospital from 2013-01 to 2015-10 were studied. The patients were at the age of (50±6) years with mean body weighting at (80±12) kg and were randomly divided into 2 groups: Traditional (T) group,n=31 and Autologous PRP back-transfusion (P) group,n=28. Blood levels of Hb, platelet counts, PT, APTT were measured at pre-induction of anesthesia (T1), before CPB (T2), prior ifnishing of CPB (T3) and at 1 h (T4), 24 h (T5), 48 h (T6) after the operation. The in-operative, 48 h post-operative volumes of allogeneic blood transfusion and the volume of chest tube drainage at 48h after operation were recorded; the complication occurrence at peri-operative period was recorded. Results: In P group, whole blood processing volume was (1269±197) ml, PRP volume was (753±78) ml, PRP separation time was (35±9) min and the separated platelets were about (22±3)% of total platelet counts. Compared with T group, P group had decreased Hb at T2 (131.0±15.0) g/L vs (101.0±10.0) g/L, decreased platelet counts at T3 (115.0±51.0)×109 /L vs (83.0±23.0)×109/L, while increased platelet counts at T4 (103.0±25.0)×109/L vs (151.0±27.0)×109/L, T5 (105.0±25.0)×109 /L vs (147.0±39.0)×109/L and T6 (101.0±26.0) ×109/L vs (149.0±35.0)×109/L, allP<0.05; P group presented reduced PT at T4 (17.6±2.1) s vs (14.1±1.1) s and T5 (17.6±2.7) s vs (13.5±0.8) s, allP<0.05. The in-operative transfusions of platelet, plasma, cold precipitation and post-operative transfusions of red blood cells, platelets, plasma, cold precipitation and the volume of chest tube drainage at 48h after operation were less in P group,P<0.05. Compared with T group, P group had the lower rates of acute post-operative lung injury (32.1% vs 19.4%), shorter mechanical ventilation time (69.1±5.9) h vs (43.1±1.5) h and ICU staying time (8.1±2.8) d vs (5.3±1.1) d, allP<0.05. Conclusion: Autologous PRP back-transfusion could reduce the post-operative bleeding and allogeneic blood transfusion for Stanford A aortic dissection surgery, it has obvious blood-saving effect.
