BACKGROUND:Lumbar degenerative disease is a common and frequently occurring disease in spinal surgery. With increasing age, the incidence rate is increased. OBJECTIVE: To elevate clinical outcomes and improve the quality of life of patients by analyzing spinal stability after lumbar implant fixation fusion and functional training in treatment of lumbar degenerative disease. METHODS: (1) We used a prospective randomized controled design. The 52 patients with I° or II° degenerative lumbar spondylolisthesis were randomly divided into two groups, with 26 cases in each group. Conventional exercises were carried out in the control group and core stabilization exercises for the treatment group, with course of treatment for 24 weeks. Curative effects of numerical rating scale and the Oswestry Disability Index were compared at 6, 12 and 24 weeks after treatment respectively. (2) Spinal stability after lumbar fusion and fixation of the implant for degenerative lumbar spondylolisthesis was evaluated by database document retrieval. RESULTS AND CONCLUSION:(1) After 24 weeks, numerical rating scale score and the Oswestry Disability Index were significantly lower in the treatment group than in the control group (P < 0.05 orP < 0.01). Core stabilization exercises apparently relieve lumbar pain and improve the ability of activities. Core stabilization exercises are better than conventional training. (2) Pedicle instrument fixation combined with interbody fusion is effective for lumbar spondylolisthesis within the second degree. Posterior interbody fusion has predominant mechanical property in maintaining spondylolisthesis orthopedic and stabilizing the structure. Correction loss and fixation failure easily occur after posterolateral fusion, but clinical effects are not affected.

Objective:To evaluate the changes in the transverse dimension and the perimeters of the maxillary archs produced by 3 self-ligating appliance systems during the leveling and aligning phases. Methods: 45 patients who had class I skeletal pattern and upper arch crowding 3-6 mm were divided into 3 groups with 15 subjects in every group. The dental casts were analyzed. Results: Statistically significant increases were recorded of all dentoalveolar widths (with the exception of intermolar width measured lingually) and arch perimeters. The increase in arch perimeter showed a significant negative relationship with the individual perimeter of the maxillary arch before treatment. No significant change was found in arch depth. Conclusion: The self-ligating appliance systems produce statistically significant increases in the transverse dentoalveolar width and the perimeter of the maxillary arch during the leveling and aligning phases of treatment.

Objective The levels of endothelin-1(ET-1) and calcitonin gene-related peptide(CGRP) in the plasma and cerebrospinal fluid(CSF)after acute cervical spinal cord injury. Method ET-1 and CGRP were determined by RIA in order to observe the effects of naloxone on levels of ET-1 and CGRP and neuronal death of cervical spinal cord. Result Levels of ET-1 in the plasma and cerebrospinal fluid(CSF)after acute cerical spinal cord injury increased significantly; but the levels of CGRP in the plasma and cerebrospinal fluid(CSF) decreased markedly. The levels of ET-1 in the plasma and cerebropinal fluid(CSF)decreased markedly after the threapy of naloxone; but levels of CGRP in the plama and cerebrospinal fluid(CSF)increased sinificantly. Conclusion These deta suggest that the lessening of CGRP and increasing of ET-1 may be some important reson causing death of neuron after acute cervical spinal cord injury, and naloxone can protecet cervical spinal cord neuron by increasing levels of CGRP and decreasing levels of ET-1.

ObjectiveIn order to enhance the curative resectability rate of pancreatic carcinoma. MethodsSixteen consecutive patients received an extended resection, which is referred to systemic dissection of regional lymph nodes and combined resection of the diseased PV/SMV based on traditional Whipple operation or the distal pancreatectomy. ResultsMean operation time was 8.5 hours. Mean intraoperative blood infusion was 1250mL. The procedure was considered curative in 11 (68.8 % ) and palliative in the other five. Postoperative complications occurred in 7 (43.8% ). Perioperative death occurred in one patient(6.25% ). Median length of hospital stay was 35 days. In nine patients undergoing curative resection,two cases survived for 1/2～1 year, six patients survived for 1～2 year and another patient has survived for more than 32 months without evidence of recurrence. ConclusionExtended resection for pancreatic cancer is technically feasible and two- third of pancreatic carcinoma invading PV/SMV alone can be expected to obtain curative resecetion.

Long-term outcomes of surgical bile duct injury (BDI) repair are affected by multiple factors, such as surgeon's experience, severity of BDI, pathological changes of the proximal duct, and the manner and timing of surgical repair. However, the timing of BDI repair is still controversial still. In this article, the authors reviewed the correlation of pathophysiologic changes of the proximal duct, repair timing and outcome discussed in English references. It was shown that pathophysiologic changes of the proximal duct are a major contributor to the timing of BDI repair.

Hepatic fibrosis is a wound-healing re-sponse to all kinds of chronic liver injury, which if persistent can lead to cirrhosis. Once develops to cirrhosis, the only ef-fective therapy will be liver transplantation. In recent years,many scholars have taken all kinds of methods to try to pre-vent liver fibrosis developing to cirrhosis. As auto adult stem cell possesses multi-directional differentiation and none reject reaction advantages, it has become the study hotspot of nu-merous researches for hepatic fibrosis therapy and acquired significant progression.
