目的 评估多普勒超声引导的痔上动脉结扎治疗Ⅱ、Ⅲ度内痔的临床应用价值。方法 对2009 年4～9月期间在我科行多普勒超声引导的痔上动脉结扎的49 例Ⅱ、Ⅲ度内痔患者从术后肛门括约肌功能、症状有效改善情况、疼痛程度及完全恢复正常生活所需时间方面进行评价。结果 术后无患者出现肛门括约肌功能失调；术后1 周、1 个月及3 个月Ⅱ、Ⅲ度内痔分别有77.8%(42/54)、87.0%(47/54)、92.6%(50/54)和59.4%(19/32)、71.9%(23/32)、78.1%(25/32)的患者单项症状得到有效改善； 术后6 h及24 h VAS 法疼痛程度评分平均分分别为1.95分和1.63分； 患者完全恢复正常生活所需时间平均为术后2.98 d。结论 多普勒超声引导的痔上动脉结扎治疗Ⅱ、Ⅲ度内痔安全有效，术后疼痛较轻且可以较快地完全恢复正常生活。
Objective To compare the clinical effect of tissue selecting therapy stapler (TST) and procedure for prolapse and hemorrhoids (PPH) in treatment of hemorrhoid in Ⅲ-Ⅳ degree. Methods Clinical data of 80 cases of hemorrhoid in Ⅲ-Ⅳ degree who treated in The First Affiliated Hospital of Harbin Medical University from May 2015 to July 2015 were retrospectively collected. All the 80 cases were divided into TST group (n=40) and PPH group (n=40) according to the surgical types. The comparison of the clinical effect of 2 groups was performed. Results The operative time, hospital stay, intraoperative blood loss, anal fall bilge feeling score, postoperative pain score at 3 time points, and the incidence of anal secretions of TST group were lower or shorter than those corresponding indexes of PPH group (P<0.05). But there was no significant difference in cure rate, the incidence of urinary retention, the incidence of anal stenosis, the incidence of intractable pain, and satisfaction situation between the 2 groups (P>0.05). All of the cases were followed up for 3 months, during the follow-up period, no one suffered from rectal vaginal fistula, fecal incontinence, and recurrence. Conclusion TST and PPH both have satisfactory effect in treatment of hemorrhoid in Ⅲ-Ⅳ degree, but TST has advan- tages of less blood loss, shorter operative time, rapid postoperative recovery, and less pain.
Objective To summarize the new progress of circulating tumor cell markers and their clinical application. Methods The related literatures about the detection and clinical application of circulating tumor cell markers in recent years were reviewed. Resuts Epithelial markers, other markers such as human epidermal growth factor receptor 2 (HER2), estrogen receptor (ER), and immuno-checkpoint genes have also become a useful means to detect the ability of malignant metastasis of circulating tumor cells (CTCs). Moreover, the epithelial-to-mesenchymal transition (EMT) and cancer stem cells (CSCs) have also received increasing attention as important CTCs markers owing to their roles in the biological progression of metastasis. Conclusions Through the detection of peripheral blood CTCs, to identify early cancer, monitoring the metastasis and recurrence of cancer and its treatment on all has the very good guiding significance. Signs of circulating tumor cells has great clinical application value in diagnosis and treatment of tumor and prognosis.
Objective To summarize progress of Warburg effect in colorectal cancer and to provide basis for diagnosis and treatment of colorectal cancer. Method The relevant literatures about the Warburg effect in the colorectal cancer in recent years were reviewed. Results The Warburg effect played a significant role in the growth, proliferation, and metastasis of the colorectal cancer cells. It was contributed to the growth of cancer cells and inhibited the apoptosis, at the same time it created the suitable environmental conditions for the tumor metastasis. Conclusions Mechanism of Warburg effec in occurrence and development of colorect cancer is not unclear. Warburg effect and relationship between its key enzyme (hexokinase, phosphofructokinase, and pyruvate kinase) and colorectal caner need to be studied so as to providing a new direction and approach for early diagnosis and treatment of colorectal cancer.
