Prognostic Factors of Patients with Spinal Chondrosarcoma: A Retrospective Analysis of 98 Consecutive Patients in a Single Center

Purpose

Chondrosarcoma (CHS) in the spine is relatively rare and minimal information has been published in the literature regarding this subject. The objective of our study was to discuss the factors that may affect outcomes of patients with spinal CHS.

Methods

Univariate and multivariate analyses were performed to identify prognostic factors for recurrence, distant metastasis, and survival of spinal CHS. T test, χ ² test and rank sum test were used to analyze a single factor for recurrence and metastasis, while survival rate was estimated using the Kaplan–Meier method. Factors with p values of ≤0.1 were subjected to multivariate analyses by binary logistic regression analyses or Cox regression analyses. p Values of ≤0.05 were considered statistically significant.

Results

A total of 98 patients with spinal CHS were included in the study. The mean follow-up period was 49.7 months (range 6–178). Recurrence was detected in 42 patients after initial surgery in our center, while distant metastasis and death occurred in 24 and 32 cases, respectively. The statistical analyses suggested that pathology grade III was closely related with distant metastasis which was an independent prognostic factor for overall survival. Total en bloc spondylectomy could significantly decrease the risk of recurrence, distant metastasis, and death of patients with spinal CHS.

Conclusions

Total en bloc spondylectomy could significantly decrease the risk of recurrence and distant metastasis, and meanwhile improve overall survival of spinal CHS. Distant metastasis which was closely associated with pathology grade III was an adverse prognostic factor for overall survival of spinal CHS.     

Detection of deception based on fMRI activation patterns underlying the production of a deceptive response and receiving feedback about the success of the deception after a mock murder crime

The ability of a deceiver to track a victim’s ongoing judgments about the truthfulness of the deceit can be critical for successful deception. However, no study has yet investigated the neural circuits underlying receiving a judgment about one’s lie. To explore this issue, we used a modified Guilty Knowledge Test in a mock murder situation to simultaneously record the neural responses involved in producing deception and later when judgments of that deception were made. Producing deception recruited the bilateral inferior parietal lobules (IPLs), right ventral lateral prefrontal (VLPF) areas and right striatum, among which the activation of the right VLPF contributed mostly to diagnosing the identities of the participants, correctly diagnosing 81.25% of ‘murderers’ and 81.25% of ‘innocents’. Moreover, the participant’s response when their deception was successful uniquely recruited the right middle frontal gyrus, bilateral IPLs, bilateral orbitofrontal cortices, bilateral middle temporal gyrus and left cerebellum, among which the right IPL contributed mostly to diagnosing participants’ identities, correctly diagnosing 93.75% of murderers and 87.5% of innocents. This study shows that neural activity associated with being a successful liar (or not) is a feasible indicator for detecting lies and may be more valid than neural activity associated with producing deception.     

Development of 39 novel polymorphic microsatellite markers for the giant mottled eel Anguilla marmorata and cross-amplification in other eel species

In this study, we have developed microsatellite markers for the giant mottled eel (Anguilla marmorata) from expressed sequence tag (EST) sequences using next-generation sequencing. Consequently, a total of 39 novel polymorphic microsatellite markers were identified in 32 individuals from Wangquan River wild population area. The range of observed heterozygosity, expected heterozygosity and polymorphism information content were 0.044–1.000, 0.285–0.946 and 0.3783–0.9016, respectively. In addition, eight loci were deviated from Hardy–Weinberg equilibrium and modified by Bonferroni correction, and the results showed no significant linkage disequilibrium between the locus pair. The amplification of cross-species was conducted in Anguilla bicolor pacifica and Anguilla japonica, which revealed the applicability of EST-SSR primers. These EST-SSR markers can provide sufficient polymorphism for population genetic studies, pedigree and genome mapping of these three kinds of closely related eels.     

50例眼内容物剜除联合羟基磷灰石义眼胎植入术病人的护理

眼内容物剜出术因保留眼球外壳,手术时不伤及眼眶内软组织,故可减少术后眼眶内软组织的萎缩,保持眼外肌其相对的解剖关系,故术后眼部凹陷较轻。在内膜腔内放入适当的植入物,以后装上义眼的外观及活动度较好。此外手术时间也较短,眼球炎病人则可避免或减少炎症向眶内扩散,但术后反应一般较眼球摘除术重,如色素膜切除不彻底,则有继发交感性眼炎的可能[1],植入物排出率较眼球摘出高。现将已施行眼内容物剜出联合羟基磷灰石义眼胎植入手术50例病人的治疗和护理体会介绍如下。1临床资料2003年1月—2003年12月在我院眼科行眼内容物剜出联合羟基磷…     

Cavernous Angiomas of the Cauda Equina: Clinical Characteristics and Surgical Outcomes

Cavernous angioma (CA) is a rare hamartomatous vascular lesion, consisting of abnormal, dilated, and packed sinusoidal vascular channels without interposed nervous tissue. CAs of the cauda equina are exceedingly rare and have been previously reported in the literature as case reports. The aim of this study was to discuss the clinical presentation and the outcomes of microsurgery for these rare lesions. We retrospectively reviewed the records of 10 patients who underwent microsurgery for CAs of the cauda equina. All patients had performed pre- and postoperative magnetic resonance imaging (MRI). CAs of the cauda equina generally exhibited mixed intensity on T₁- and T₂-weighted images. Contrast-enhanced T₁-weighted images showed heterogeneous enhancement. The hemosiderin ring which surrounded the cauda equina CA was rare. Gross total resection was achieved in all cases. All patients were followed up, with a mean duration of 41.1 months. Long-term neurological function was improved in nine patients and remained stable in one patient. No recurrence was observed on MRI. CAs should be considered in the differential diagnosis of cauda equina tumors. Because of the excessive vascularity of CAs, en bloc resection is recommended. For symptomatic patients, early surgery should be performed before neurological deficits deteriorate.
