ABSTRACT
Objective:To investigate the prognostic effect of polymorphnuclear neutrophil (PMN) in cervical cancer. Methods:Patients (n=92) who underwent curative surgery for the treatment of stage Ib and IIa cervical cancer according to the International Federation of Gynecology and Obstetrics (FIGO) were assessed to determine their tumor-infiltrating CD66b-positive neutrophils through immuno-histochemistry. Assessment results were then analyzed to identify their correlation with recurrence-free survival (RFS) as an end point. Kaplan-Meier method was used for survival curve analysis, and a Cox proportional hazard model was utilized for univariate and multi-variate analyses. Results:The RFS of the group with a density of CD66b-positive neutrophils above the median in cervical cancer tis-sues was significantly shorter than that of the group with a density of CD66b-positive neutrophils below the median (P=0.001). Univari-ate and multivariate analyses revealed adenocarcinoma (HR=3.020;95%CI=1.340-6.805;P=0.008), lymph node metastasis (HR=2.450;95%CI=1.065-5.637;P=0.035), and high neutrophil density (HR=2.866;95%CI=1.274-46.447;P=0.011) as independent prognostic fac-tors of short RFS. Conclusion:The increasing number of tumor-infiltrating neutrophils in cervical cancer tissues was correlated with short RFS of patients with cervical cancer.
ABSTRACT
ABSTRACT An investigation was conducted to identify the allochthonous microbiota (entire intestine) and the autochthonous microbiota in proximal intestine (PI) and distal intestine (DI) of four species of Indian air-breathing fish (climbing perch; Anabas testudineus, murrel; Channa punctatus, walking catfish; Clarias batrachus and stinging catfish; Heteropneustes fossilis) by PCR based denaturing gradient gel electrophoresis (DGGE). High similarities of the allochthonous microbiota were observed between climbing perch and murrel, walking catfish and stinging catfish, indicating similar food behavior. The autochthonous microbiota of PI and DI from climbing perch and murrel revealed more similarity, than the result obtained from walking catfish and stinging catfish. The autochthonous microbiota of climbing perch and murrel were similar with regard to the allochthonous microbiota, but no such similarity was observed in case of walking catfish and stinging catfish. The fish genotype and intestinal bacteria are well matched and show co-evolutionary relationship. Three fish species has its unique bacteria; autochthonous Enterobacter cloacae, Edwardsiella tarda and Sphingobium sp. in DI of climbing perch, Pseudomonas sp.; allochthonous and autochthonous in PI of walking catfish and uncultured bacterium (EU697160.1), uncultured bacterium (JF018065.1) and uncultured bacterium (EU697160.1) for stinging catfish. In murrel, no unique bacteria were detected.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the clinical efficacy of incising spinal pia mater to relieve pressure and unilateral open-door laminoplasty with internal screw fixation for treatment of the dated spinal cord injury.</p><p><b>METHODS</b>From March, 2009 to July, 2010, 16 cases with chronic cervical cord injury underwent spinal dura mater incision and unilateral open-door laminoplasty with internal screw fixation. Nerve functions of pre- and postoperation were evaluated by Frankel classification and the Japanese Orthopaedic Association (JOA) scale.The improvement rate of JOA score at the indicated time was recorded.</p><p><b>RESULTS</b>Postoperative Frankel classification rating of 16 patients improved obviously.JOA scores at the 1st month, 3rd month, 6th month, and 12th month after surgery were 7.9 ± 2.3, 8.5 ± 1.6, 8.9 ± 2.1, and 12.4 ± 2.5, respectively, and significantly increased compared with that prior to surgery (5.5 ± 0.6). At the end of follow-up period, JOA score was significantly higher than that of pre-treatment (P<0.05). The recovery was relatively rapid during the first 3 months following the surgery, then entered a platform period.</p><p><b>CONCLUSION</b>It is effective for patients with dated spinal cord injury to undergo spinal decompression and laminoplasty.</p>

In this article, the status of spindle assembly checkpoint and the alteration of its major component, Mad2 protein level were examined in A2780 and SKOV3 ovarian cancer cell lines. Recombinant eukaryotic expression plasmid pEGFP-Mad2 was transfected into paclitaxel-resistant SKOV3 cells and Mad2 protein was knocked down by Mad2-specific siRNA in paclitaxel-sensitive A2780 cells. Then the expression level of Mad2 gene was detected by Western blotting. Flow cytometry revealed that SKOV3 cells were not fully arrested in G2/M phase in contrast to A2780 cells in the presence of paclitaxel. However, paclitaxel sensitivity assay showed that sensitivity to paclitaxel was reversed after the transfection in both cell lines in terms of number of cells arrested at G2/M phase and the expression of Bcl-2 was significantly changed. These results suggest that weakened spindle checkpoint with reduced expression of Mad2 is associated with resistance to paclitaxel in ovarian cells and Bcl-2 may be involved in this process.
