[Effects of positive end expiratory pressure ventilation upon respiratory function and hydrophobic surfactants proteins in rabbit with seawater respiratory distress syndrome].
To investigate the effects of positive end-expiratory pressure (PEEP) ventilation upon respiratory function and lung surfactant protein B (SP-B)/SP-C in seawater respiratory distress syndrome (SW-RDS) rabbit. ⋯ PEEP ventilation can improve the oxygenation indices and lung compliance in SW-RDS animals. And such an effect is correlated with both the mRNA expressions of SP-B/SP-C and mechanical distension.

Comparative Study[Dose distributions of proton beam therapy for hepatocellular carcinoma: a comparative study of treatment planning with 3D-conformal radiation therapy or intensity-modulated radiation therapy].
A comparative dose distribution study has been undertaken between proton beam therapy (PBT), 3-dimensional conformal radiation therapy (3D-CRT) and intensity-modulated radiation therapy (IMRT) in the treatment of hepatocellular carcinoma (HCC), so as to assess the potential advantages of PBT. ⋯ Compared with 3D-CRT, PBT reduced the dose to the normal liver tissues and nonliver OARs significantly, even with 20 to 30.3 percent of dose escalation. Compared with IMRT, PBT reduced the dose to the normal liver tissues significantly, even with 20 to 30.3 percent of dose escalation. PBT reduced the dose to the right kidney and stomach significantly. No significant difference was observed respect to the dose to spinal cord.

[Study of spinal sagittal plane curve in patients with thoracolumbar intervertebral disc herniation].
To understand the curve of thoracolumbar junction in patients with thoracolumbar intervertebral disc herniation and analyze the relation between thoracolumbar intervertebral disc herniation and spinal sagittal curve. ⋯ The Cobb angles of sagittal plane of thoracolumbar junction of spine in patients with thoracolumbar intervertebral disc herniation are greater than those in healthy controls. The abnormal spinal curve is possibly responsible for thoracolumbar intervertebral disc herniation by abnormal biomechanical action.

[A special type of discogenic low back pain: normal signal intensity of magnetic resonance imaging with abnormal discography].
To report a group of special patients showing a normal signal intensity of MRI with a positive discography and discuss its pathogenesis and clinical significance. ⋯ Patients who are refractory to conservative care and have normal signal intensity in lumbar disc MRI and who are suggested as discogenic origin and might need further treatment such as minimal invasive surgery or lumbar interbody fusion should still be examined by discography.

[Association study of SIM2 gene polymorphisms with susceptibility to congenital scoliosis in a Chinese Han population].
To investigate whether polymorphisms of SIM2 gene are associated with congenital scoliosis (CS) in a Chinese Han population. and explore the relationship of between polymorphisms of SIM2 and clinical phenotypes of CS. ⋯ Genetic variants of SIM2 gene may not be associated with the susceptibility to CS and different clinical phenotypes of CS in Chinese Han population.
