Objective To explore the effectiveness, safety and applicability of focused ultrasound (FU) in rural patients with cervicitis-related diseases. Methods Patients with cervicitis-related diseases (n=8 352) from 80 township health centers of 9 counties in Chongqing were enrolled in this multicenter clinical study, and they were treated with CZF Model of FU for one time and then were visited in the following 3 months. According to the category 4 scoring method and the curative index, the effectiveness, safety and applicability in 7027 cases (1 156 mild cases, 5 312 moderate cases, 559 severe cases) with complete records were analyzed. The influencing factors were also analyzed with logistic regression analysis. Results A total of 6 413 cases (91.26%) were treated within 5 minutes. After 3-month follow-up, the total effective rate was 99.59%, and 5 012 cases (71.32%) were cured. Just little or medium amount of vaginal bleeding occurred in 656 cases (9.34%) after treatment, while only 12 cases (0.17%) had bleeding in the similar amount tomenstruation, which were relieved by hemostasis and anti-inflammatory treatment. Conclusion As a promising new therapy, focused ultrasound therapy for treating cervicitis-related diseases is safe and effective, with little postoperative bleeding and short-term of vaginal effusion, so it is suitable to be popularized in rural areas.
【摘要】 目的 探讨宫颈上皮内瘤变（CIN）和宫颈鳞癌（SCC）组织中人类染色体端粒酶基因（hTERC）的表达和临床意义。 方法 收集2007年10月-2009年6月经病理学证实的116例宫颈脱落细胞标本，其中LSIL（CINⅠ）30例、HSIL（CINⅡ/Ⅲ）37例、SCC 16例、宫颈炎33例，用荧光原位杂交（FISH）方法检测脱落细胞hTERC基因。 结果 在宫颈炎、LSIL、HSIL和SCC组中hTERC基因的表达率分别是6.1%、16.7%、51.4%和93.8%，其中，HSIL、SCC组与宫颈炎组比较，hTERC基因阳性率差异有统计学意义（Plt;0.05），LSIL组与HSIL组比较、LSIL组与SCC组比较、HSIL组与SCC组比较，差异有统计学意义（Plt;0.05），且随着病变程度增加，hTERC基因表达率增加。 结论 hTERC基因在细胞学LSIL、HSIL和SCC中表达异常，且随病变程度增加阳性表达率也增加，可作为宫颈癌癌前病变进展的生物遗传学监测指标，并有望成为宫颈癌早期筛查方法之一。【Abstract】 Objective To explore the clinical significance and expression of the human telomerase gene (hTERC) in the cervical intraepithelial neoplasia (CIN) and squamous carcinoma of the cervix (SCC). Methods According to histological biopsy from October 2007 to June 2009, 116 pap smears were divided into LSIL (n=30), HSIL (n=37), SCC (n=16), and cervicitis (n=33) groups. Fluorescence in situ hybridization (FISH) was used to detect the expression of hTERC. Results Positive expression rate of hTERC was 6.1% in cervicitis group, 16.7% in LSIL group, 51.4% in HSIL group, and 93.8% in SCC group, respectively. Compared to cervicitis group, the expression of hTERC in HSIL and SCC groups was significantly higher (Plt;0.05). Among LSIL, HSIL, and SCC groups, there were significant differencec in hTERC expression between every two groups (Plt;0.05). From LSIL to SCC, the expression of hTERC increased obviously. Conclusion Abnormal expression of hTERC exists in LSIL, HSIL, and SCC patients, which significantly increases during malignant development. It may be a biogenetics monitor index of cervical precancerosis and will be a screening marker for cervical cancer.
目的:探讨聚焦超声治疗慢性宫颈炎的安全性和有效性。方法:回顾性分析2003年1月至2006年12月我院门诊诊断治疗的慢性宫颈炎患者,行聚焦超声治疗后并于3月内随访的574例患者,分析其安全性及有效性。结果:574例中,痊愈 378例(65.9%),显效155例(27.0%),总有效率96.7%。治愈率与糜烂面积及深浅程度有关(Plt;0.05)。超声治疗后部分患者出现阴道少量流液及血性分泌物。结论:聚焦超声应用于慢性宫颈炎的治疗安全有效,疗效确切,不良反应及并发症小,值得推广。
