鞘内注射miR-212反义锁核酸对骨癌小鼠痛行为的影响

目的研究骨癌痛发展和维持过程中小鼠脊髓水平miR-212表达的变化规律及连续鞘内注射miR-212反义锁核酸LNA．anti—miR-212对骨癌痛小鼠痛行为的影响。方法本实验分为两个部分：（一）骨癌痛小鼠脊髓水平miR-212表达的变化规律：C3H／HeJ雄性小鼠36只,随机分为假手术组（sham组,n=18）和肿瘤组（T组,n=18）。sham组小鼠在右侧股骨远端骨髓腔注射不含肿瘤细胞的仪一MEM,T组小鼠在右侧股骨远端骨髓腔注射纤维肉瘤细胞NCTC2472,建立骨癌痛模型。在术前1d,术后4d、7d、10d、14d、21d,sham组和T组各随机取三只小鼠处死,取脊髓腰膨大标本,用Real-timePCR的方法检测脊髓水平miR一212的表达情况。（二）连续鞘内注射LNA—anti-miR-212对骨癌痛小鼠痛行为的影响：C3H／HeJ雄性小鼠24只,随机分为四组：L组（鞘内注射LNA-anti—miR一212,n=6）、L’组（鞘内注射LNA＇-negativecontrol,n=6）、C组（鞘内注射溶媒无核酸酶水,n=6）和S组（假手术处理,n=6）。L组、L’组和C组小鼠在右侧股骨远端注射纤维肉瘤细胞NCTC2472,S组小鼠在右侧股骨远端骨髓腔注射不含肿瘤细胞的仪一MEM。所有小鼠于术前1d、术后4d、7d、10d、14d测小鼠痛行为指标,包括自发抬足次数和机械缩足阈值（PWMT）,术后14d,L组、L’组、C组小鼠分别鞘内注射LNA—anti—miR-21212pmol／5山、LNA＇-negativecontrol12pmol／5I＊1和无核酸酶水5I＊1,连续鞘内注射7d,1次／d,每天测小鼠痛行为指标,至术后第21天。结果miR-212的表达变化表现为：与基础值相比,sham组和T组小鼠在术后第4天,脊髓水平miR一212明显升高（P〈0．05）;与基础值和sham组相比,T组小鼠脊髓水平miR-212在术后7d、10d、14d、21d均明显升高（P〈0．05）。连续鞘内注射LNA—anti—miR-212改善骨癌痛小鼠痛行为：术后19d至21d,与L’组和c组相比,L组小鼠PWMT[19d（1．07-4-0．16）g,20d（1．13±0．21）g,21d（1．27±0．21）g）]明显升高（P〈0．05）,自发抬足次数明显降低[19d（6．674-1．04）,20d（6．62±1．39）,21d（6．47±1．17）]（P〈0．05）。与14d给药前相比,L组小鼠术后19d至21d的PWMT明显升高（P〈0．05）,自发抬足次数明显降低（P〈0．05）。结论骨癌痛发展过程中,脊髓水平miR-212表达量升高。连续鞘内注射LNA-anti—miR一212可以缓解骨癌小鼠痛行为。     

4种肿瘤标志物在肺癌病理分型、分期中的临床价值

目的：探讨CEA、SCC-Ag、NSE、CA125与肺癌病理分型以及临床特征之间的关系。方法：应用电化学发光方法检测109例肺癌患者血清中4种肿瘤标志物水平。结果：CEA在腺癌中的水平明显高于其他类型的肺癌（P＝0．003）;SCC-Ag在鳞癌中的水平明显高于其他类型的肺癌（P＝0．006）;NSE 在小细胞肺癌中的水平明显高于其他类型的肺癌（P＝0．001）。CEA在T3、T4分期表达的水平明显高于T1和T2分期（P＝0．041）。NSE和CA125在N2和N3期患者中表达水平明显高于N0和N1期患者（P＜0．05）。CEA在有远处转移的患者中表达水平明显高于无转移的患者（P＝0．038）。CEA和SCC-Ag转移部位越多,其表达越高（P＜0．05）。CEA在Ⅳb 期患者中表达水平明显高于Ⅰ＋Ⅱ＋Ⅲ和Ⅳa 期患者（P＝0．037）。CA125在有胸腔积液的患者中表达水平明显高于无胸腔积液的患者（P＝0．001）。结论：CEA对晚期腺癌的诊断价值较高, SCC-Ag是诊断鳞癌有价值的标志物,NSE对小细胞肺癌有较高的诊断价值。CEA与临床分期正相关,高表达预示分期晚,低表达则对分期参考作用小。CEA及SCC-Ag高浓度应高度警惕有无多部位转移,CA125水平高提示可能存在胸膜转移。     

DNA flow cytometry of histological material from human gastric cancer

DNA flow cytometry was performed on fixed embedded histological material from 56 radical gastrectomies for human gastric cancer. The ploidy and proportion of cells in the DNA synthetic phase of the cell cycle (S phase fraction) were estimated and the results correlated with histological features. DNA aneuploidy was encountered in 73 per cent of cases. Aneuploid and diploid tumours both had significantly higher fractions of cells in S phase than normal mucosa. S phase fractions for aneuploid tumours were higher than diploid tumours. There was a trend for tumours exhibiting an infiltrating mode of growth and poor tubule formation to have a diploid DNA content and low S phase fraction. No difference was observed between the results obtained from tumours with or without lymph node metastases. Early uniform fixation greatly improved the quality of the flow cytometry results measurable by a reduction in the mean coefficient of variation.     

Combined treatment with X-ray irradiation and 5-aminolevulinic acid elicits better transcriptomic response of cell cycle-related factors than X-ray irradiation alone

Purpose: 5-Aminolevulinic acid (ALA) is a precursor of the photosensitizer protoporphyrin (PpIX) used in photodynamic therapy. In our previous work, PpIX enhanced the generation of reactive oxygen species by X-ray irradiation. In this study, we evaluated the potential of ALA as an endogenous sensitizer to X-ray irradiation.

Methodology: Tumor-bearing C57BL/6J mice implanted with B16-BL6 melanoma cells were subsequently treated with irradiation (3?Gy/day for 10 days; total, 30?Gy) plus local administration of 50?mg/kg ALA 24?hours prior to each irradiation (ALA-XT). Tumor-bearing mice without treatment (NT), those treated with ALA only (ALAT), and those treated with X-ray irradiation only (XT) were used as controls.

Results: ALA potentiated tumor suppression by X-ray irradiation. In microarray analyses using tumor tissue collected after 10 sessions of fractional irradiation, functional analysis revealed that the majority of dysregulated genes in the XT and ALA-XT groups were related to cell-cycle arrest. Finally, the XT and ALA-XT groups differed in the strength of expression, but not in the pattern of expression.

Conclusions: mRNA analysis revealed that the combined use of ALA and X-ray irradiation sensitized tumors to X-ray treatment. Furthermore, the present results were consistent with ALA’s tumor suppressive effects in vivo.     

基质金属蛋白酶-9及其相关因子与卵巢癌的研究进展

卵巢癌是一种恶性程度高、发病隐匿的妇科恶性肿瘤,死亡率居妇科恶性肿瘤之首。多数卵巢癌诊断时已是晚期。MMP-9即基质金属蛋白酶-9,是重要的蛋白水解酶,参与肿瘤侵袭与转移的多步骤过程。大量研究证明:MMP-9能降解细胞外基质的多种成分,包括明胶和基底膜的Ⅳ型胶原,Ⅳ型胶原是构成阻止肿瘤侵袭屏障的重要成分,同时MMP-9还可以促进肿瘤细胞的生长,减少肿瘤细胞凋亡,促进肿瘤血管的生成,在卵巢癌的侵袭与转移中发挥重要作用。多种因子被发现与卵巢癌有关,研究其机制时发现与MMP-9的表达水平相关,下调MMP-9的表达水平成为卵巢癌新的治疗方法。本文对MMP-9及其相关因子在卵巢癌中的研究进展进行综述,并对其在卵巢癌的研究与应用前景作出展望。     

Asian society of gynecologic oncology workshop 2010

This workshop was held on July 31-August 1, 2010 and was organized to promote the academic environment and to enhance the communication among Asian countries prior to the 2nd biennial meeting of Australian Society of Gynaecologic Oncologists (ASGO), which will be held on November 3-5, 2011. We summarized the whole contents presented at the workshop. Regarding cervical cancer screening in Asia, particularly in low resource settings, and an update on human papillomavirus (HPV) vaccination was described for prevention and radical surgery overview, fertility sparing and less radical surgery, nerve sparing radical surgery and primary chemoradiotherapy in locally advanced cervical cancer, were discussed for management. As to surgical techniques, nerve sparing radical hysterectomy, optimal staging in early ovarian cancer, laparoscopic radical hysterectomy, one-port surgery and robotic surgery were introduced. After three topics of endometrial cancer, laparoscopic surgery versus open surgery, role of lymphadenectomy and fertility sparing treatment, there was a special additional time for clinical trials in Asia. Finally, chemotherapy including neo-adjuvant chemotherapy, optimal surgical management, and the basis of targeted therapy in ovarian cancer were presented.
