OBJECTIVETo discuss the clinical effects and superiority of applying external fixation and bone transport to treat osteomyelitis and bone defect of femoral bone.
METHODSFrom August 2008 to December 2013,16 patients with osteomyelitis and bone defect of femoral bone were treated including 11 males and 5 females with an average age of 42 years old ranging from 13 to 62 years old. The average course of disease was 18 months ranging from 2 months to 4.5 years, and the average length of bone defect was 7.8 cm ranging from 4.5 to 15 cm. The bone defect of all cases were treated by external fixation and bone transport, the bone transport began at 1 week after operation, 1 mm per day and 4 times per day.
RESULTSAll patients were followed up for 10 to 36 months (means 22.5 months). One patient did not cooperate with treatment leads to the failure, then took the amputation. The remaining 15 cases of osteomyelitis were under control, including 12 cases of bone transport achieved one stage bone union, 3 cases achieved bone union via bone graft from iliac bone. The bone union time was 5 to 13 months(means 7.9 months). Thirteen patients almost obtained the same length of two lower extremities,2 patients had shortening of 1.5 to 2 cm. The time of moving the external fixation was from 6 to 16 months (means 9.3 months).
CONCLUSIONApplication of external fixation and bone transport is an effective method in treating the osteomyelitis and bone defect that can control the infection, eradicate wounds, and be the equalization of limb length.

OBJECTIVETo evaluate effects of different treatments on patients with osteoporotic vertebral fracture after percutaneous kyphoplasty in pain and function.
METHODSFrom March 2010 to March 2012,138 patients (165 vertebrae) with thoracic and lumbar vertebral osteoporotic fracture were randomly divided into three groups (control group, treatment group and comprehensive group), 46 cases in each group, and all patients were treated by PKP. Control group were treated with calcium and calcitriol after operation, treatment group added salmon calcitonin see calcimar based on control group, comprehensive group added incrementality waist musculi dorsi function exercise based on treatment group. VAS, ODI scores and BMD before operation, 3 d, 2 weeks, 1 month, 6 months and 12 months after operation were detected and compared.
RESULTSAll operation were performed successfully,38 cases (45 vertebrae) in control group, 36 cases (44 vertebrae) in treatment group and 40 cases (49 vertebrae) were obtained complete following up, there was no significant meaning in following time among three groups (P>0.05). Postoperative VAS and ODI scores at 3 d, 2 weeks and 1 month among three groups were lower than that of before operation (P<0.01). Compared with control group, postoperative VAS score at 3 d, 2 weeks and 1 month were decreasedin treatment group and comprehensive group, but there was no significant meaning in ODI scores (P>0.05). At 6 and 12 months after operation,there was no significant differences in VAS and ODI between control group and treatment group (P>0.05), while VAS score in comprehensive group decreased much than other two groups,decreased continuously (P<0.01). At 12 months after operation, BMD among three groups were increased more than preoperative,and BMD in comprehensive group was more obviously than that of in control and treatment group.
CONCLUSIONPKP, an effective method for the treatment of thoracic and lumbar vertebral osteoporotic fracture, could improve short-term clinical effects by adding calcitonin with calcium supplements and activated vitamin D. Waist musculi dorsi function exercise could improve long-term clinical effects of PKP and improve quality of life.

AIM: To investigate the characteristics of pathological injury and its relationship with the transformation of energy metabolism of hypertrophic cardiomyocytes after hypoxia-reoxygenation. METHODS: Cultured rat cardiomyocytes were induced to be hypertrophy by angiotensin Ⅱ (Ang Ⅱ) and norepinephrine (NE). Glucose oxidation rate (GOR), glucolysis rate (GLR) and fatty acid oxidation rate (FOR) were determined by liquid scintillation counting, and cell apoptosis was detected by TUNEL. RESULTS: (1) Compared with the normal cardiomyocytes (NC), the GOR and GLR were slightly higher and the FOR was slightly lower in the group of hypertrophic cardiac cells (HC) than that in the group of normal cardiomyocytes cultured under the normal oxygen partial pressure. The apoptosis rate had no difference between the two groups. (2) The apoptosis rate of hypertrophic cardiomyocytes after hypoxia was significantly higher than that of hypertrophic cardiomyocytes in normal culture. It was higher and moreover, some necrosis cardiomyocytes appeared after reoxygenation. (3) GOR and FOR in both group (NC and HC) were slightly lower in a time-dependent manner after hypoxia than that in each group in normal culture condition. GLR had no difference in both group. The GOR was more lower in both NC and HC group when reoxygenation than that at the point of hypoxia for 2 hours, but the GLR and FOR were significantly higher in HC than that in NC when reoxygenation. (4) The GOR was significantly higher and the GLR and FOR were significantly lower in the hypertrophic cardiomyocytes group (HC) with dichloroacetate (DCA, 1 000 ?mol/L) or trimetazidine (TMZ, 1 ?mol/L) treated respectively than that in the responded hypertrophic cardiomyocytes after stimulation by hypoxia-reoxygenation. In the meanwhile, the apoptosis rate also was markedly lower in the treated hypertrophic cardiomyocytes group. CONCLUSION: The transformation of energetic metabolism pathway plays an important role in the pathogenesis (mainly the apoptosis) of the hypertrophic cardiomyocytes after hypoxia-reoxygenation.
