Objective To investigate the effect of morphine preconditioning on mitochondrial permeability transition pore (MPTP) and its protective mechanism after myocardial ischemia-reperfusion injury. Methods A rat model of ischemia-reperfusion injury was established. Forty rats were injected with 2-3[H] DOG and then divided into 4 groups randomly: a sham operation (S) group, an ischemia-reperfusion injury (IR) group, a morphine preconditioning (Mp+IR) group, and a cyclosporine A preconditioning (CsA+IR) group. We monitored the concentrations of serum creatine kinase-Mb (CK-Mb) and cardiac troponin I (cTnI), and measured myocardial mitochondrial 2-3[H] DOG, cytochrome c content, Ca2+ concentration ([Ca2+]m), the velocity of Ca2+ intake and reaction half time of mitochondrial permeability transition pore (MPTP t1/2) in the 4 groups. Results The concentrations of serum CK-Mb and cTnI decreased more in the Mp+IR group and the CsA+IR group than those of the IR group. The concentrations of 2-3[H]DOG and [Ca2+]m in the IR group were evidently higher but the level of cytochrome c was lower than those of the sham operation group. The concentrations of 2-3[H] DOG and [Ca2+]m in the Mp+IR group decreased whereas the concentration of cytochrome c increased compared with those in the IR group. Mitochondrial 2-3[H]DOG content was positively correlated with the concentration of calcium (r=0.797, P<0.01). The 2-3[H]DOG and [Ca2+]m content were negatively correlated with cytochrome c in the IR group (r=-0.805 and r=-0.648, respectively, P<0.01). MPTP t1/2 in the IR group was shortened evidently, and that in the Mp+IR and CsA+IR group was significantly lengthened. Conclusion Morphine preconditioning may have myocardial protective effect through unburdening the calcium overload and lengthening the MPTP t1/2.

Objective To explore the diagnostic value of virtual bronchoscopic navigation (VBN) for peripheral pulmonary lesions. Methods 200 cases with peripheral pulmonary lesions (0.8 cm < diameter < 4.0 cm) were divided into VBN and control group from June 2014 to June 2015. VBN group: VBN guided ultrafine bronchoscope to the target bronchus, control group: ultrafine bronchoscopy with chest CT as a reference guided to the target bronchus. Results There were no significant differences in the diagnosis rates between VBN group and control group in 200 patients (χ2 = 3.31, P = 0.069); But, the diagnosis rates with diameter more than 2.0 cm and less than or equal to 2.0 cm had statistically significant differences of VBN group and control group (χ2 = 13.45, 5.31, P = 0.000, 0.021, respectively); We also found that the mean time of biopsy tool reach to the lesions had significant differences between the two groups (P = 0.047). There were no significant differences in total checking time and complications (P = 0.230, 0.960, respectively). Conclusions Virtual bronchoscopic navigation did not improve the diagnosis rate of pulmonary peripheral lesions, but shortened the time to locate the lesions.
