半乳糖凝集素-1蛋白在宫颈病变组织中的表达及其与高危型人乳头瘤病毒的关系

目的:探讨半乳糖凝集素-1(Galectin-1)蛋白在宫颈上皮内瘤变(CIN)及宫颈癌中的表达及其与高危型人乳头瘤病毒(HR-HPV)的关系。方法:用免疫组织化学法检测宫颈癌(54例)、CINⅠ(10例)、CINⅡ(20例)、CINⅢ(25例)和正常宫颈组织(20例)中Galectin-1蛋白的表达,用第二代杂交捕获法(HC-Ⅱ)检测HR-HPV感染情况,分析Galectin-1与CIN及HR-HPV的关系。结果:Galectin-1蛋白在正常宫颈、CINⅠ、CINⅡ、CINⅢ和宫颈癌组织中的阳性表达率分别为5.0%、20.0%、40.0%、56.0%、48.1%,随着CIN病变程度的加重,Galectin-1蛋白阳性表达逐渐增强;宫颈癌和CINⅡ、CINⅢ的Galectin-1蛋白阳性表达率明显高于正常宫颈组织和CINⅠ(P<0.01),宫颈癌与CINⅡ、CINⅢ间比较、差异无统计学意义(P>0.05)。宫颈癌中Galectin-1蛋白阳性表达在有否淋巴结转移、组织学分级、临床分期和有否HR-HPV的感染中比较,差异有统计学意义(P<0.05,P<0.01),在不同组织学类型中比较,差异无统计学意义(P>0.05)。结论:Galectin-1蛋白表达增强与宫颈病变的进展有一定关系,HR-HPV可能通过诱导宫颈上皮高表达Galectin-1而促使宫颈癌发生、发展。     

Dynamin 2 expression as a biomarker in grading of cervical intraepithelial neoplasia

Objective

Dynamin 2, which plays a role in endocytosis, is known to be required for HPV infection on host cells. We investigated dynamin 2 as a biomarker in grading of cervical intraepithelial neoplasia (CIN) by comparing with Ki-67 expression and the type of HPV infection (low-risk vs. high-risk).

Study design

We performed immunohistochemical stains of dynamin 2 and Ki-67 on tumor samples of patients with CIN and the type of HPV infection was investigated.

Results

All the patients with reactive changes (n = 7) or normal (n = 4) did not show dynamin 2 expression. There were 33, 14, and 12 cases with CIN I, II, and III, respectively, and there was a negative correlation between the degree of dynamin 2 expression and the severity of CIN lesions with statistical significance (P < 0.001). Negative expression of dynamin 2 was more sensitive for the detection of CIN II/III than high expression (2+) of Ki-67 (96.2% vs. 73.1%, P = 0.041). Among patients in whom HPV infection was detected, the degrees of dynamin 2 expression were not associated with the type of HPV infection (low-risk vs. high-risk). Overall, there was a negative correlation between the expression patterns of Ki-67 and dynamin 2.

Conclusion

We found that dynamin 2 may be a helpful biomarker in grading of CIN lesions and a candidate biomarker for detecting low grade CIN with high sensitivity.

不同宫颈癌临床分期患者外周血中T淋巴细胞及NK细胞的表达分析

目的分析宫颈癌患者外周血中T淋巴细胞及其亚群以及NK细胞的表达情况。方法前瞻性分析145例在我院就诊的宫颈癌患者的临床资料,按照宫颈癌FIGO临床分期差别分为:宫颈癌Ⅰ期38例、宫颈癌Ⅱ期42例、宫颈癌Ⅲ期35例、宫颈癌Ⅳ期30例;同期选择体检正常女性30例作为对照组。应用流式细胞仪检测各组患者外周血CD3^+、CD4^+、CD8^+T细胞亚群、调节性T细胞(Treg)以及NK细胞数量,同时计算各亚群的比例以及Treg占CD4^+T细胞的比例。应用多元Logistic回归分析评估各细胞亚群数量及比例与宫颈癌临床分期的相关性。结果与对照组相比,宫颈癌患者CD3^+T细胞、CD4^+T细胞、NK细胞数量以及CD4^+/CD8^+比值均较低,Treg/CD4^+比值较高(均P <0.05),而CD8^+T细胞数量差异无统计学意义(均P>0. 05)。随宫颈癌病理严重程度递增,CD3^+T细胞、CD4^+T细胞、NK细胞数量以及CD4^+/CD8^+比值逐步降低,Treg/CD4^+比值逐步增高(均P <0.05),而CD8^+T细胞数量差异无统计学意义(均P>0.05)。多元Logistic回归分析显示,Treg/CD4^+比值是宫颈癌临床分期的危险因素,CD4^+T细胞、CD4^+/CD8^+比值及NK细胞是其保护性因素(均P<0.05)。结论宫颈癌患者细胞免疫功能均不同程度降低,晚期患者降低最显著。检测T淋巴细胞亚群及NK细胞可用于宫颈癌患者免疫监测,为临床治疗及预后评估提供参考。     

卡铂术前不同分级盆腔动脉灌注化疗宫颈癌组织内铂离子浓度的对比研究

目的:对比术前超选择子宫动脉与髂内动脉前干灌注卡铂化疗宫颈癌癌组织内的铂离子浓度,为临床上选择合适的靶血管实施动脉化疗提供依据.方法:选择经病理检查证实为宫颈癌、且癌灶较大易于取材的患者14例,随机分为超选择子宫动脉灌注化疗组和髂内动脉前干灌注化疗组,以卡铂300 mg/m2一次性给药.在灌注后0、10、20分钟分别钳取宫颈癌组织,测定标本内铂离子浓度.结果:①峰值及曲线形态:两组癌组织内铂离子浓度的高峰值均出现在化疗结束后即刻,且随时间的延长而快速下降,呈一下降曲线.超选择子宫动脉灌注化疗组的峰值是251.00±119.39 ng/mg,髂内动脉前干灌注化疗组的峰值是186.73±110.66 ng/mg,差异无统计学意义(P>0.05).②浓度一时间曲线下面积(AUCo～20 min)值:超选择子宫动脉灌注化疗组化疗后0～20分钟的癌组织内铂离子浓度AUC0～20 min为3432.50±2099.94 ng.min/mg,髂内动脉前干灌注化疗组为2722.36±1474.34 ng.min/mg,差异无统计学意义(P>0.05).结论:超选择子宫动脉灌注与髂内动脉前干灌注化疗后癌组织内铂离子无论是峰浓度还是AUC0～20 min均无明显差别,但从减少动脉化疗并发症的角度,应根据宫颈癌的分期情况选择合适的靶血管管施动脉化疗.

青藤碱与卡铂对宫颈癌Hela细胞增殖的协同抑制研究

目的:研究选择性环氧合酶-2(COX-2)押制剂青藤碱(sinomenine,SIN)对宫颈癌Hela细胞生长的影响及其与卡铂联合对宫颈癌Hela细胞的协同抑制作用,初步探讨SIN在宫颈癌中的作用机制.方法:MTT法检测SIN及其与卡铂联合对宫颈癌Hela细胞增殖的影响;流式细胞仪检测处理后宫颈癌Hela细胞周期及凋亡的变化.结果:SIN以时间和剂量依赖性特点抑制宫颈癌Hela细胞的增殖,其与卡铂联合对宫颈癌Hela细胞的增殖具有协同抑制作用.流式细胞仪细胞周期分析表明,SIN处理组G1期细胞比例明显增加,S期细胞比例明显减少;卡铂处理组结果相反.细胞凋亡分析表明,SIN处理组细胞凋亡率较对照组升高,呈时间和剂量依赖性特点;两药联合处理组细胞凋亡率较单药处理组升高.结论:SIN以时间和剂量依赖性抑制宫颈癌Hela细胞的增殖,其作用机制与改变细胞周期分布、促进细胞凋亡有关.SIN与卡铂联合对宫颈癌Hela细胞的增殖具有协同抑制作用,其机制可能与共同影响细胞周期分布、促进细胞凋亡有关.     

Randomised placebo-controlled trial of outpatient (at home) cervical ripening with isosorbide mononitrate (IMN) prior to induction of labour – clinical trial with analyses of efficacy and acceptability. The IMOP Study

Objective  To determine whether isosorbide mononitrate (IMN), self-administered vaginally by women at home, improves the process of induction of labour.
Design  Randomised double blind placebo-controlled trial.
Setting  Large UK maternity hospital.
Population or Sample  Nulliparous women with a singleton pregnancy, cephalic presentation ≥37 weeks gestation, requiring cervical ripening prior to induction of labour.
Methods  IMN ( n  = 177) or placebo ( n  = 173) self-administered vaginally at home at 48, 32 and 16 hours prior to the scheduled time of admission for induction.
Main outcome measures  Admission to delivery interval and women's experience of induction of labour.
Results  IMN did not shorten the admission to delivery interval as compared with placebo [mean difference of −1.6 hours (95% CI −5.1,1.9, P  = 0.37)], despite being more effective than placebo in inducing a change in Bishop score [mean difference of 0.65 (95% CI 0.14,1.17, P  = 0.013)]. While both groups found the overall experience of home treatment to be positive, (mean score of 3.8/10 ± 2.3/10 for the IMN group, where 1 = extremely good and 10 = not at all good) women in the placebo group found it marginally more positive than those in the IMN group (just over half a unit on a 10-point scale, P  = 0.043). There were no differences between the groups in the pain or anxiety experienced or willingness to take the treatment in a subsequent pregnancy.
Conclusions  IMN self-administered vaginally at home does not shorten admission to delivery interval despite a significant effect on cervical ripeness assessed using the Bishop score. However, women report positive views on cervical ripening at home, and the setting deserves further investigation.
