目的 研究前列腺癌细胞中miR-221的表达情况及其对癌细胞增殖的影响。方法 运用实时荧光定量PCR(qRT-PCR)检测miR-221在前列腺正常细胞株与前列腺癌细胞株中表达的差异情况,利用细胞转染构建miR-221过表达LNCaP和DU145细胞株,再通过CCK8细胞增殖实验检测细胞增殖情况的变化。结果 qRT-PCR检测细胞株发现miR-221在PC3、LNCaP和DU145三种前列腺癌细胞株中表达量均比前列腺正常细胞株PrEC低 (F=254.197,P<0.001),其中两两比较差异也均有统计学意义。细胞转染技术构建的miR-221过表达LNCaP和DU145细胞株,经qRT-PCR结果显示,miR-221在LNCaP和DU145细胞株中的表达水平明显升高(LNCaP,倍数变化=2.24,t=3.46,P<0.01;Du145,倍数变化=2.24,t=4.29,P<0.01)。细胞增殖实验结果显示,过表达了miR-221的LNCaP(P<0.001)和DU145(P<0.001)细胞生长速度慢于对照组。结论 实验证明miR-221表达过度能减慢前列腺癌细胞的增殖,miR-221有可能成为前列腺肿瘤治疗的生物学标志物。

Objective To explore clinical efficacy of different surgical methods in treatment of papillary thyroid cancinoma combined Hashimoto's thyroiditis. Methods Eighty-seven patients of unilateral papillary thyroid carcinoma in patients with Hashimoto's thyroiditis who were treated in our hospital between April 2015 and May 2016 were divided into two groups according to surgical treatment methods, namely observation group and control group. Forty-four patients in the observation group received ipsilateral thyroid lobe + isthmus resection, while forty-three patients in the control group were given total thyroidectomy. Changes of parathyroid and thyroid functions, intraoperative blood loss, length of incision and operation time after different surgical procedures were compared. Results The hypoparathyroidism rate (0.00%), hypothyroidism rate (2.27%), and incision length (4.00±1.10)cm, blood loss (33.60±8.30)mL, operation time (130.73±34.67)min in the observation group were lower than those in the control group (11.63%), (97.67%), (9.70±2.33)cm, (76.70±23.90)mL, (160.94±39.70) min, the difference was statistically significant (P<0.05). Conclusion Ipsilateral thyroid lobe and isthmus resection shows obvious effect in treatment of papillary thyroid carcinoma with Hashimoto's thyroiditis, effectively reduces the incidence of parathyroid and thyroid dysfunction, improves intraoperative blood loss, length of incision and operation time.

目的 比较腹腔镜前列腺癌根治术(laparoscopic radical prostatectomy,LRP)后发生尿失禁(postprostatectomy incontinence,PPI)与没有发生PPI的患者在尿动力学上的差异,为临床诊疗提供尿动力学依据。方法 对87例LRP术后的患者按术后是否并发PPI分成两组,行尿动力学检查后进行比较分析。结果 PPI组患者术中保留一侧或双侧神经血管束的比例少于非PPI组,且最大尿道闭合压(maximum urethral closure pressure,MUCP)、最大膀胱容量(maximum cystometric capacity,MCC)、排尿时膀胱开口压力和最大逼尿肌压均较非PPI组低。而腹压漏尿点压试验阳性与临床上是否漏尿并不完全相符。多变量回归分析表明,术中保留神经血管束、MUCP和MCC是PPI的相关因素。结论 PPI与LRP术中保留神经血管束、MUCP和MCC独立相关。尿动力学检查能为更精准有效指导临床治疗提供依据。

Objective To compare the urodynamic parameters in men with and without postprostatectomy incontinence(PPI) after laparoscopic radical prostatectomy(LRP). Methods 87 patients of prostatic carcinoma after LRP were divided into two groups according to have PPI or not. After urodynamic study, the data were collected to find the difference. Results Overall, the proportion of preservation of unilateral or bilateral neurovascular bundles(NVBs) during LRP was lower in PPI group than that in non-PPI group. Besides, the patients in PPI group had lower maximum urethral closure pressure (P=0.04), maximum cystometric capacity (P=0.04), detrusor pressure during opening (P=0.02)and maximum detrusor pressure (P<0.001), as compared with those in non-PPI group. In the multivariate logistic regression, the preservation of unilateral or bilateral NVBs, MUCP and MCC were identified as the related factor with PPI. Conclusion PPI is significantly associated with the preservation of unilateral or bilateral NVBs, MUCP and MCC. Urodynamic test can be used to make the treatment for PPI. It will be more accurate and effective in clinical practice.

Objective To investigate the expression and clinical significance of Sonic hedgehog(Shh), Glioma-associated oncogene homolog -1(Gli-1) and Matrix metalloproteinase-2(MMP-2) in gastric cancer.Shh and Gli-1 are the molecules of Hedgehog(Hh) signaling pathway. MMP-2 is the member of matrix metalloproteinase family. Methods The expression of Shh,Gli-1 and MMP-2 proteins was examined by immunohistochemistry in the human gastric cancer tissues and the human gastric polyp and the normal gastric mucosa tissues of 40 cases. Results The positive expression rates of Shh,Gli-1 and MMP-2 in gastric cancer were 62.5%,67.5% and 72.5% respectively, which were significantly higher than those in the gastric polyp tissues (the positive expression rates were 27.5%,37.5% and 32.5% respectively) and normal gastric mucosa tissues (the positive expression rates were 22.5%,17.5% and 12.5% respectively),P<0.05.The expression of Shh,Gli-1 and MMP-2 was not correlated with the sex,age or histological type(P>0.05),but was correlated with depth of invasion,differentiation level and lymphonode metastasis in gastric cancer(P<0.05). The expression of Shh and Gli-1 was positive correlated with MMP-2. Conclusion Hedgehog(Hh)signaling pathway may have great effects on enhancing the invasive ability of gastric cancer by upregulating MMP-2 protein through some unknown mechanisms.The combined detection of the expression level of Shh,Gli-1 and MMP-2 in gastric cancer tissues might be used as an Objective references for assessing the prognosis of gastric cancer.
