Objective To study the effect of the expansive open-door laminoplasty on the three-dimensional motion and stiffness of the cervical spine. Methods 55 cases after open-door laminoplasty of cervical spine due to myelopathy were follow-up for an average of 35.9 months. Cervical axial symptoms, neural functionality (JOA scoring system) and pre- and post-surgery dynamic cervical spine lateral X-ray films were evaluated. The Three-dimensional Motion and Stiffness of the Cervical Spine of Human Body Measuring Equipment was used in 12 post-operative open door laminoplasty cases and 10 pre-operative cases to measure the active and passive range of motion(ROM), load-displacement relationship, stiffness of cervical spine and torque caused by the isometric contraction of the extensors and flexors of the cervical spine. Results The average rate of improvement was 66. 2%. The excellent and good rate was 78.2%. The number of cases with distinct or severe cervical axial symptoms increased after the surgery ( P < 0. O1 ) . The patients who have severe axial symptoms tend to have less curved cervical spine (P < 0. 01 ) . There was no significant statistic difference between the severity of post-surgery cervical axial symptoms and JOA improvement level (P > 0. 05). The active and passive ROM of extension, rotation and lateral bending of cervical spine were decreased after the surgery ( P < 0. 05), and the main affection was on the middle and lower part of the cervical spine. The load-displacement figure of cervical spine can fit into an exponential equation T= b0eb1θ. In each direction, the lateral bending had the strongest stiffness, then the extension and flexion. The stiffness of rotation was the weakest. The stiffness of cervical spine of the post-surgery group was stronger than that of the contrast group. Conclusion The open-door laminoplasty of cervical spine damages the static mechanic balance on the sagittal plane and decreases the ROM and the flexibility of cervical spine. The curvature of the cervical spine is related to the severity of the axial symptoms and seems not to be related to the JOA score improvement.

Objective To explore the causes and solutions of rehospitalization of the high-risk neonates. Methods The data collection form was designed based on the literature reviewing and the discussion of the nursing quality management team. Results The samples were retrospectively collected from January 2015 to October 2015. There were 106 cases readmitted among the 3012 discharged cases with the ratio of 3.52%. The average interval of readmission were (4.92±4.0) days, most of the cases were readmitted in 7 days after the first discharge with a ratio of 83.95%, the ratio of readmission within 3 days was 38.68%and that was 45.28%for the readmission within 4~7days. For the Preterm infants, the ratio of readmission within 3 days was 21.69%which was higher than that of the full term (16.98%), there was no statistically significant difference between the two groups(chi-square= 1.45, P>1.45). While the ratio of readmission within 7 days for premature infants was 49.06%(52/106), which was higher than that of full term infants [34.91%(37/106)], and there was statistically significant difference between the two groups(chi-square = 5.45, P<0.05). Jaundice was found to be the major reason for unplanned rehospitalization with the ratio of 50.94%. When compared the incidence of readmission contributed by improper feeding between the low birth weigh and normal birth weight infants, there was nostatistical significance (chi-square = 3.58, P>3.58). But when compared between preterm infants and full term, a higher ratio was found in preterm infants (16.04%), and there was statistically significant difference (chi-square = 5.83, P< 0.05). Conclusion One week after discharge was the peak time of readmission.Jaundice was the main factor of readmission. Premature babies were more likely to have readmission due to feeding problems.

Pituitary tumors are clinically common neoplasms involved in the central nervous system. The endoscopic endonasal approach is a safe and feasible technique for managing pituitary tumors. Endoscopic technology has been increasingly used in clinical practice because it results in limited nasal injury, decreased operating time and postoperative complications, and quick postoperative re-covery. This study aims to evaluate the advantages and effectiveness of the endoscopic endonasal transsphenoidal approach for the re-moval of pituitary tumors. This approach should be further modified and optimized in clinical trials and practices.

ObjectiveTo investigate the causes of groin lymphatic fistula after transluminal ultrason ic angioplasty (TUA) in the treatment of deep vein thrombosis(DVT) of lower extremity through groin incision. Methods A retrospective anal ysis of the causes of groin lymphatic fistula(GLF) in 72 patients with DVT after treatment of ultrasonic ablation was made. ResultsTUA and thr ombectomy using Forgaty balloon catheter for DVT of lower extremity achieved successful recanalization in all the 72 cases (100%). Of the 72 cases,51 had i liac vein stenosis,the venous stenosis disappeared after balloon dilation;amo ng the 51 cases ,6 cases received stent placement. GLF occurred postoperati vely in 60 cases. No death occurred in this series. ConclusionsTUA is an effective method in the treatment of DVT of lower extremity,but t he incidence of postoperative GLF is high.The causes of GLF may be related to the injury of lymphatic vessels, increase of quantity of lymph flow induced by increased venous pressure, infection, surgical technique factors and postop erative medicine therapy etc.
