Objective In order to study the effect of cold stress on the secretory function of rat ovary, the changes of hCG-induced progesterone and cAMP were observed and the livability of the oocytes was determined. Methods The rat luteal and granulose cells and the oocytes were cultured, progesterone and cAMP content was determined by radioimmunoassay kit (RIA kit) under 37 ℃, 0 ℃, -5 ℃, -10 ℃,-15 ℃, -20 ℃ and -25 ℃ respectively. The livability of the oocytes was determined by MTT assay. Results At -5 ℃ to -25 ℃, the content of progesterone in the luteal cells and granulose cells medium decreased compared with the control group. At 0 ℃～-25 ℃, the content of cAMP in the luteal cells and granulose cells medium was higher compared with the control. The livability of the oocytes was decreasing from -15 ℃. Conclusion Cold stress can inhibit hCG-induced progesterone secretion in the luteal and granulose cells of rats in the one hand, and can increase cAMP, decrease the livability of the oocytes in the other hand.

Objective To analyze the multi-slices spiral CT (MSCT) findings of hepatic alveolar echinococcosis(HAE), and to evaluate the value of MSCT for diagnosis of HAE. Methods Twenty-six cases with HAE were scanning by MSCT. The raw data were transmitted to advanced workstation for reconstruction imaging. Correlated studies were made between the CT features and pathology or other imaging results. Results Altogether 28 lesions were detected. They all revealed as heterogeneous hypodense mass with ill-defined boundary in plain CT but were easily being distinguished from surrounding parenchyma after contrast medium injection.Characteristics of the lesions include different amount of calcification (26/26), liquefied necrosis in center area (20/26), peripheral lacunae or alveolar signs (15/26), compensatory hypertrophy of healthy hepatic part (18/26) and the retraction in the involved hepatic lobe or segment (12/26). The lesions that located at or extended to hepatic hilum caused dilatation of intra-hepatic biliary ducts(9/26), splenomegaly (12/26), and ascites (1/26). MSCT angiography (CTA) depicted signs of abnormalities of hepatic vessels such as compression, displacement, encasement and occlusion. Compared with findings of operation, the sensitivity, specificity and positive prediction value of CTA for evaluating the hepatic artery system disorders were 88%, 96% and 93%, respectively; and for portal venous system were 95%, 100% and 95%, respectively; while for hepatic venous system were 96%, 86% and 96%, respectively. Conclusion MSCT is able to comprehensive display the CT features and vessels complication of HAE. It provides reliable imaging for both accuracy diagnosis and proper treatment of the disease.

Objective To evaluate the mechanical stability of alternative reconstruction methods after total en bloc spon?dylectomy in the lower lumbar spine. Methods Eight adult fresh cadaveric lumbosacral spines (L1-S1) were adopted. Total en bloc spondylecotmy of the L4 vertebra was performed after intact testing. Four designed reconstruction samples were tested for the range of motion (ROM) of the spine:1) expandable artificial vertebral body and short posterior instrumentation at L3-L5 (SP), 2) ex?pandable artificial vertebral body and short posterior instrumentation with additional anterolateral fixation at L 3-L5 (ASP), 3) ex?pandable artificial vertebral body and multilevel posterior instrumentation at L2-S1 (MP), 4) expandable artificial vertebral body and multilevel posterior instrumentation with additional anterolateral fixation at L2-S1 (AMP). Nondestructive biomechanical test?ing was performed on each construct under loading control. The ROM for each construct was obtained by applying pure moments in flexion, extension, lateral bending, and axial rotation. Results In flexion, extension and lateral bending, the ROM of all the re?constructed constructs significantly decreased compared to the intact. The ROM of specimens with anterolateral fixation was less when compared to the ones without additional fixation. In lateral bending, MP (L:1.87° ± 0.32° , R:1.97° ± 0.33° ), ASP (L:1.89° ± 0.37°, R:2.08°±0.36°) and AMP (L:1.32°±0.29°, R:1.61°±0.33°) provided significantly less ROM than the SP (L:3.14°±0.35°, R:3.44°±0.34°). In axial rotation, the ROM of ASP (L:4.21°±0.58°, R:4.02°±0.59°) and AMP (L:3.56°±0.55°, R:3.52°±0.48°) was significant decreased when compared to the intact state (L: 7.47° ± 1.00° , R:7.57° ± 0.84° ). MP (L:6.33° ± 0.71° , R:5.88° ± 0.62°), ASP and AMP showed significantly less ROM than the short posterior fixation (L:9.28°±1.01°, R:9.48°±0.98°). AMP sig?nificantly decreased the ROM compared to MP. Conclusion After total en bloc spondylectomy of lower lumbar, long segmental fixation provided more stability to the construct than the short one. Compared to posterior fixation, circumferential fixations showed a higher stability. In contrast, multilevel segmental instrumentation with circumferential fixation did not provided more stability than the short constructs.

Objective To investigate procedure and therapeutic effect of resection and reconstruction for axis tumors through the sub mandible approach. Methods Between December 2004 to June 2010,17 patients with axis neoplasm underwent tumor resection and antero-posterior reconstruction through the combined the sub mandible-inner sternocleidomastoid muscle (SMIS) approach and posterior approach. Tumor lesions involved C2 in 11 cases, C2-3 in 4, C2-4 in 2. Eight cases involved vertebral body, and 9 involved both vertebral body and element. Fourteen primary lesions including 4 giant cell tumors, 4 plasmocytomas, 2 chordomas, 2 eosinophilic granulomas, 1 hemangiopericytomas and 1 lymphoma, and 3 metastatic lesions were involved in this study. Three types of reconstruction in upper cervical spine including titanium mesh plus vertically placed titanium plate, titanium mesh plus obliquely placed titanium plate and trimmed titanium mesh alone, were adopted after anterior tumor resection, and then posterior tumor resection and reconstruction were performed. Results All patients experienced pain relief and neurological improvement after surgery. Except for one incidence of screw pull-out which was corrected by a revision surgery, solid fusion was achieved in all patients. A follow-up period of 6 months to 6 years was available for this study. One patient died of cerebral infarction 9 months postoperative. Two patients with chordoma relapsed 13 months and18 months postoperative, respectively, of whom one died of high plegia and respiratory failure, and the other was alive with disease. Two patients with metastasis died of multiple remote metastases 12 months and 18 months postoperative, respectively. Conclusion Through the SMIS apporach, a satisfactory exposure can be obtained for axis tumor resection and reconstruction. Anterior reconstruction of upper cervical spine after tumor resection can be achieved with internal fixation system of cervical spine, which can improve intraopera-tive safety. The combined anterior reconstruction and posterior occipito-cervcial fixation can provide immediate stability, and benefit maintaining stability of upper cervical spine.

Objective To investigate the safety and feasibility of en-bloc resection of a primary sacral chordona based on a 3-dimensional printing model.Methods 31 patients with primary sacral chordoma underwent en-bloc resection via a onestage posterior approach or combined anterior and posterior approaches in our oncology department from January 2013 to December 2014.They comprised 21 males and 10 females of mean age (49.2±12.5) years (range,26-67 years).Preoperative 3-D printing models were created by 3D printing technology,it included tumor tissue,the around vascular and nerves involved in sacral chordoma.The sacral chordomas were en-bloc resection with decompression and internal fixation.Results With the mean (29.0±6.8)months follow-up (range from 19 to 41),all patients underwent en bloc excision via 26 cases with posterior approach,5 cases combined posterior and anterior approaches in one stage.The mean operative time and estimated blood loss were (275.0±58.1) min and (3 250.0±1 304.4) ml,respectively.The visual analogue scale (VAS) score was (5.6±1.9) in average (range from 3 to 9) at preoperation,and (2.0±1.5) at post-operation,which was significantly lower than that of preoperation,and the pain was relief obviously.There were 13 cases in grade C,11 cases in grade D,7 cases in grade E of American Spinal Injury Association (ASIA) grade neurological function before surgery,compared with the pre-operation,there were 5 cases in grade C,6 cases in grade D,20 cases in grade E of post-operation,which was significantly improved.MSTS (Musculoskeletal Tumor Society) 93 score was 6-29 points (20.0％-96.7％) at the follow-up 3 months after surgery,with the average of (19.8 ± 5.8) points,which excellent in 8 cases,good in 14 cases,general in 5 cases,poor in 4 cases.Two cases of dysporia for the reasons of resecting on one side of the S1,2 nerve roots involved by the sacral chordoma,after sacrificing the nerve root of complete tumor resection,the urine left dysfunctional,while the pain of other 29 patients were thoroughly relief after surgery.The ones were relieved with the disturbance of sensation of the perineum before the operation.2 cases were recovery of leakage of cerebrospinal by the drainage of lumbar cistern with normal temperature.One hypostatic pneumonia patient was cured by anti-inflammatory.One with the urinary infection got better by the effective bladder irrigation,which had diabetics mellitus with the bladder stoma before.1 case of skin necrosis due to vascular thrombosis before operation,recevied flap translocation half month after surgery,got recovery 3 months later.Only one underwent tumor resection for the recurrence at 15 months follow-up.Conclusion It is feasible and safe to perform en bloc resection of primary sacral chordoma.This is the most effective means of managing method of the marginal resection of the tumor.Preoperative 3-D printing modeling enables better anatomical understanding of the relationship between the tumor,and can avoid vascular and nerves tissue injury,which can also assist in planning the surgical procedure,and be worth recommendation.
