0.05), reduced obviously in hydrotherapy group as compared with sham group. Postsynaptic density (PSD) in hippocampus was more in intervention group than non-intervention group. Conclusion Enriched environment stimulus and hydrotherapy can promote the rehabilitation of neonatal rats with HIBD. The intervention effects of enriched environment and combined application of enriched environment stimulus and hydrotherapy is better than hydrotherapy. The change of NMDA receptor in hippocampus might be one of the mechanism.

Objective:To observe the effect of simvastatin at different doses on the inflammatory factors and renal function in se-nile patients with diabetic kidney disease ( DKD) . Methods:Totally 160 cases of DKD patients were randomly divided into the control group, low dose group, conventional dose group and high dose group. All the patients were given the foundation treatment, and the low dose group, conventional dose group and high dose group was respectively given simvastatin 10, 20,40 mg·d-1 . The changes of in-flammatory cytokines (CRP, ICAM-1 and IL-1β) and renal index (BUN, Cr, UAER, 24hUpro and Uβ2-MG) among the groups were observed and compared before and after the 4-week treatment. Results:CRP in the high dose group after the treatment was significantly decreased when compared with that before the treatment and that in the control group after the treatment, and the difference was statisti-cally significant (P<0. 05). ICAM-1 in the low dose group, conventional dose group and high dose group was significantly decreased when compared with that before the treatment and that in the control group after the treatment, and the difference was statistically sig-nificant (P<0. 05). IL-1β in the four groups after the treatment had no obvious change when compared with that before the treatment, and there was no significant difference among the groups (P >0.05). BUN in the four groups after the treatment had no obvious change when compared with that before the treatment, and there was no significant difference among the groups (P>0. 05). Cr and UAER in the four groups after the treatment were significantly decreased (P<0. 05), those in the low dose group, conventional dose group and high dose group after the treatment were significantly lower than those in the control group after the treatment (P<0. 05), and those in the conventional dose group and high dose group after the treatment were significantly lower than those in the low dose group after the treatment (P<0. 05). 24hUpro in the low dose group, conventional dose group and high dose group after the treatment was significantly decreased when compared with that before the treatment and that in the control group after the treatment (P<0. 05). Uβ2-MG in the low dose group, conventional dose group and high dose group after the treatment was significantly decreased when com-pared with that before the treatment and that in the control group after the treatment (P<0. 05), that in the conventional dose group and high dose group after the treatment was significantly decreased when compared with that in the low dose group after the treatment (P<0. 05), and that in the high dose group after the treatment was significantly lower than that in the conventional dose group after the treatment (P<0. 05). ③There was no statistically significant difference in the adverse reactions incidence among the four groups (P>0. 05). Conclusion:Simvastatin can improve diabetic nephropathy conditions in two aspects of inflammation factors and renal in-dex, and simvastatin at high dose shows more advantages.

Hearing loss caused by cochlear damage is the main symptom of sudden deafness (SD). Some patients also suffer from vestibular symptoms. In recent years, more attention has been paid to the vestibular dysfunction in patients with SD. The lesions could involve the whole inner ear in SD patients with and without vertigo. Comprehensive evaluation of vestibular function may help us understand the extent of lesions in sudden deafness and analyze the pathogenesis of disease. A less involvement of inner ear lesion may indicate a better hearing recovery.

OBJECTIVETo construct a 3D finite-element model of the craniofacial complex with the original DICOM data of CT and to investigate the preliminary biomechanical characteristics with different directions and magnitudes of retractive forces to the maxilla of rhesus monkeys.
METHODSA male rhesus monkey with mixed dentition was used. Spiral CT was performed to establish a 3D finite-element model of the craniofacial complex. The ANSYS 12.1 software was used to analyze craniofacial complex displacement.
RESULTSEach landmark showed larger displacement with increasing force value. The displacement values and force size exhibited a linear relationship. In the x-axis direction, all displacements were small. In the y-axis direction, all displacements showed significantly higher changes with increasing force value displacement. In the z-axis direction, the A-point and ANS point moved downward, but PNS moved upward.
CONCLUSIONLoading retractive force resultes in an apparent backward and clockwise rotation on the maxilla with no obvious effects on the width of the upper jaw.

Objective To evaluate the effect of 27G pars plana vitrectomy (PPV) and 25G PPV on idiopathic epiretinal membrane (IMEM). Methods Thirty-eight eyes of 38 patients with IMEM were enrolled into this retrospective and comparative study. Eighteen eyes were treated with 27G PPV (group A), 20 eyes underwent 25G PPV (group B) voluntarily. The best corrected visual acuity (BCVA), intraocular pressure (IOP), slit-lamp microscope, indirect ophthalmoscopy, fundus color photograph, ocular coherence tomography (OCT) and counting of corneal endothelial cells (CEC) were examined before the surgery. BCVA results were converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity. There was no statistically significant difference between two groups in terms of BCVA, IOP, foveal macular thickness (FMT), the counting of CEC and CEC hexagon rate before the surgery (t=1.627, 0.860, 0.293, 1.238, 0.697;P>0.05). All operations were performed by the same doctor. Operation time for vitrectomy and peeling membrane was recorded. BCVA, IOP, OCT, FMT, counting of CEC and the improvement of metamorphopsia were observed on 1, 7 days and 1, 3 months after PPV. Results The mean operation time for vitrectomy in group A and B were (6.7±2.8), (10.5±3.3) min, respectively. The mean operation time for vitrectomy in group A was significantly longer than that in group B (t=3.084, P<0.05). The mean operation time for peeling membrane in group A and B were (10.2±5.2), (11.0±5.9) min, respectively. There was no statistically significant difference between two groups in terms of the time for peeling membrane (t=1.970, P=0.187). On 1, 7 days and 1, 3 months after PPV, the difference of BCVA (t=1.463, 0.683, 0.961, 1.226;P=0.833, 0.509, 0.699, 0.744) and IOP (t=1.314, 1.262, 0.699, 1.116;P=0.763, 0.721, 0.534, 0.712) between two groups were not statistically significant. On 1 day after PPV, there were 2 eyes and 5 eyes with<9 mmHg (1 mmHg=0.133 kPa) IOP in group A and B. On 7 days and 1, 3 months after PPV, the difference of FMT between two groups were not statistically significant (t=1.257, 1.368, 1.437;P=0.735, 0.745, 0.869). On 3 months after PPV, the difference of CEC between two groups were statistically significant (t=2.276, P<0.05);the difference of hexagon rate between two groups were not statistically significant (t=1.473, P=0.889). Conclusion The efficacy of 27G PPV for IMEM appears similar to 25G PPV. But 27G PPV has a shorter operating time for vitrectomy, a more stable IOP and a minimal damage to CEC.
