Methods Using individualized health management for 66 elderly patients with colorectal cancer for 3 months, the level of hope, anal sphincter function and quality of life were evaluated. Results After 3 months, the defecation function of the patients recovered well to reach 90.91%, and the difference was statistically significant (P<0.01); After 3 months, the scores of each dimension of Herth Hope Index (HHI) and SF-36 were significantly improved, and the difference was statistically significant (P<0.01). Conclusion The implementation of individualized health management for the elderly patients with colorectal cancer may improve the survival level and improve the quality of life.

目的 通过检测结直肠癌患者血清及组织中癌胚抗原(CEA)及β₂微球蛋白(β₂MG)的表达,探讨结合两者在结直肠癌诊断中的作用。方法 对30例结直肠癌患者的血清、癌组织和癌旁组织进行CEA及β₂MG检测,设置对照组为行肠镜检查的正常健康体检者30例。分别对比CEA及β₂MG在结直肠癌中的关系,进一步对比CEA及β₂MG两者在结直肠癌在结直肠癌患者中的肿瘤大小、分期、浸润深度及转移的关系。 同时对结直肠癌及健康体检者的一般情况如性别、年龄、CEA、β₂MG、血红蛋白及白蛋白进行对比,以进一步了解CEA及β₂MG 在结直肠癌中的重要性。结果 CEA在结直肠癌患者癌组织、癌旁组织及血清中升高的比例为100%、10%、47%;β₂MG在结直肠癌患者癌组织、癌旁组织及血清升高的比例为60%、57%、23%;联合血清中CEA及β₂MG升高的比例为63%;正常对照组中的CEA升高的比例为33%,β₂MG升高的比例为67%;无论CEA还是β₂MG在结直肠癌中均有一定比例的升高,联合两者升高更明显。结论 CEA及β₂MG是恶性肿瘤特别是结直肠癌的重要指标,联合两者的检测提高结直肠癌的早期诊断。

Objective To detect the expression of carcinoembryonic antigen and β₂ microglobulin in serum and tissue of patients with colorectal cancer, and to explore their roles in the diagnosis of colorectal cancer. Methods 30 patients with colorectal cancer were examined for CEA and β₂MG in serum, cancer and para-cancer tissues, and 30 healthy persons with normal colonoscopy were selected as the control group. The expressions of CEA and β₂MG in serum and tissues were compared, and the relationship between CEA and β₂MG and tumor size, stage, depth of invasion and metastasis were analyzed. Results The increased in proportion of CEA in cancer tissue、para-carcinoma tissue and serum of colorectal cancer was 100%、10%、47%; Similarly, the increased in proportion of β₂MG was 60%、57%、23%;Combined calculation the increased in proportion ofCEA and β₂MG in serum of colorectal cancer was 63%;In the normal control, the increased in proportion of CEA was 33%;The increased in proportion of β₂MG was 67%.Both CEA and β₂MG in colorectal cancer had a certain proportion, the rise of joint both was obviously more. Conclusion CEA and β₂MG are important markers of malignancy, especially colorectal cancer. Combined detection of CEA and β₂MG can improve the early diagnosis of colorectal cancer.

目的 研究超声内镜(EUS)对结直肠癌(CRC)术前分期和指导手术方案的应用价值。方法 选取我院2014年11月—2015年11月结直肠外科收治的52例CRC患者,均接受根治性切除术治疗并经术中病理观察确诊,并以手术病理TNM分期结果作为金标准。术前对入选患者行超声内镜检查,参考金标准回顾性分析超声内镜的TNM分期诊断效果。结果 该52例CRC患者EUS诊断结果显示肿瘤侵犯浸润T分期(T1～T4)准确率分别为87.50%、80.00%、94.12%、83.33%,较手术病理金标准无差异(P>0.05);EUS诊断淋巴结转移N分期(N0～N2)准确率分别为76.92%、79.17%、86.67%,其中N0、N2准确率较金标准无差异(P>0.05),但N1分期准确率较金标准偏低(P<0.05)。结论 虽然ENS对淋巴结转移程度尤其是N1的诊断准确度存在一定误差,但从整体来看EUS能较好的观察CRC患者肿瘤侵犯浸润深度和判断淋巴结转移情况,术前结合EUS诊断结果有利于患者术前病理分期,并为选择合适的手术方案提供参考依据。

Objective To study the application value of endoscopic ultrasonography (EUS) in preoperative staging of colorectal cancer (CRC) and guidance of surgical procedures. Methods 52 cases of patients with CRC who were admitted in the department of colorectal surgery of our hospital from November 2014 and November 2015 were selected. All of them underwent radical resection and were confirmed by surgical and pathological observation. Surgical and pathological TNM staging results were taken as golden standard. Before surgery, endoscopic ultrasonography was performed in the selected patients. Referring to the gold standard, TNM staging diagnostic effects of endoscopic ultrasonography were retrospectively analyzed. Results The EUS diagnostic results of 52 patients with CRC showed that the accuracy rates of tumor invasion T stage (T1-T4) were 87.50%, 80.00%, 94.12% and 83.33% respectively. There was no significant difference, compared with surgical and pathological golden standard (P>0.05); The accuracy rates of EUS in diagnosis of lymph node metastasis N stage (N0-N2) were 76.92%, 79.17% and 86.67%, respectively. There was no significant difference in accuracy rate in N0 and N2, compared with the gold standard (P>0.05), but the accuracy in N1 stage was lower than that of gold standard (P<0.05). Conclusion Although ENS has some errors in the diagnosis of degree of lymph node metastasis, especially N1, on the whole, EUS can be better to observe the depth of tumor invasion and lymph node metastasis in patients with CRC. The diagnosis combining with EUS before surgery is helpful to the preoperative pathological staging, and provide reference for the selection of appropriate surgical procedures.

目的 调查结直肠癌患者癌因性疲乏状况,研究其动态变化趋势,为临床护理提供理论依据。方法 选用癌症疲乏量表(CFS)对96例结直肠患癌患者于术前一周、术后3~4天、出院前1~2天进行调查分析。结果 三次调查患者的癌因性疲乏水平有差异(P＜0.01),术后3~4天疲乏程度最重,出院前1~2天次之,术前一周最轻;三次调查结肠癌患者的疲乏水平均高于直肠癌患者,两组疲乏水平有差异(P＜0.05)。结论 结直肠癌患者于住院不同时期存在不同程度的疲乏,应针对疾病各时期特点为患者量身裁定护理干预措施,改善其疲乏症状。

Objective To investigate the dynamic changes of cancer-related fatigue (CRF) in patients with colorectal cancer. Methods Totally 96 patients with colorectal cancer were investigated by Cancer Fatigue Scale in three times: a week before patients' surgery, 3~4 days after patients' surgery and 1~2 days before discharge, respectively. Results Scores of fatigue of colorectal cancer patients were significantly different among three measurement points(P＜0.01). The scores of fatigue in the second survey were the highest. The third survey took second place and the first survey was the lowest. The score of fatigue in colon cancer patients were higher than rectal cancer patients in survey, with significant difference(P＜0.05). Conclusion There were obvious differences of fatigue in different periods for colorectal cancer patients in hospital. Inventions should tailor for patients according to characteristics of different periods to improve fatigue.

目的 分析经直肠彩超引导下不同前列腺穿刺方式的阳性率及其相关因素,探讨安全的穿刺方案。方法 回顾性分析接受经直肠彩超引导下前列腺穿刺的701例患者临床资料,所有患者均接受系统性13点穿刺活检,并假设13点穿刺中减少前列腺中线3个穿刺点为10点穿刺术式,加之标准的6点穿刺术式。比较上述穿刺术式的阳性率,分析T-PSA、前列腺体积、PSA体积密度(PSAD)、有无前列腺结节对穿刺阳性率的影响。结果 随前列腺穿刺针数的增加,活检阳性率增高。同一穿刺方式,不同T-PSA组间、不同前列腺体积组、不同PSAD组阳性率有差异。T-PSA>100 ng/mL时,三种穿刺方式的阳性率无差异;T-PSA<100 ng/mL时,6点穿刺法阳性率较低,而10点穿刺、13点穿刺阳性率无差异。前列腺体积>80 mL时,不同穿刺法阳性率有差异。PSAD<0.5 ng/mL²时,10点、13点穿刺阳性率无差异。结论 前列腺穿刺活检阳性率随穿刺针数增多而增加,可根据PSA水平、前列腺体积、PSAD选择个体化穿刺方案。

        儿童孤立性直肠溃疡综合征（SRUS）是一种较为罕见的慢性直肠疾病,儿童发病率低且缺乏明确统计学数据。该病主要表现为便血、排黏液便和排便不尽感,临床诊断较为困难,常易误诊为其他疾病。其发病机制尚不明确,可能与排便习惯异常、直肠黏膜异常、血管异常以及遗传易感性等多种因素有关,其中 CHEK2 基因的 p.H371Y 突变可能在发病机制中起关键作用。诊断需综合病史、体格检查以及排粪造影、超声内镜、肠镜检查与组织病理活检等多种辅助检查手段。治疗上目前尚无统一指南,主要包括改善饮食和排便习惯、生物反馈治疗、药物治疗、内镜下治疗和外科手术治疗等,但总体治疗难度较大且复发率较高。本文对儿童 SRUS 的流行病学、发病机制、临床表现、诊断和治疗等方面的研究进展进行综述,旨在提高临床医师对该病的诊疗水平,为未来进一步的研究提供参考依据。

       Solitary rectal ulcer syndrome（SRUS）in children is a chronic and benign disease of the rectum characterized by ulcers. The clinical incidence of SRUS in children is not high, but it is prone to misdiagnose and miss diagnosis,which can delay the optimal treatment opportunity. This article reviews the research progress on the epidemiology,pathogenesis, clinical manifestations, diagnosis and treatment of SRUS in children, aiming to improve the diagnostic and therapeutic level of clinicians.

       结直肠癌（CRC）是全球第三大最常见的癌症，也是癌症相关死亡的第二大常见原因。结直肠癌肝转移（CRLM）是导致CRC患者死亡的主要原因，根治性肝切除术是目前有望治愈CRLM的唯一途径，但大部分患者不能进行根治性肝切除术。通过早期发现并进行针对性干预，能够改善患者的治疗效果及预后。文章通过综述CRLM的发病机制、诊疗现状及最新纳米诊疗方法，为深入探索高效诊疗方法提供思路。
