简介:摘要家庭内部56天内多人毒鼠强中毒较少见。该文报道5例患者因误服人为毒鼠强蓄意投毒食物引起毒鼠强中毒,主要临床表现为头痛,头晕、乏力、恶心、呕吐、四肢阵发性强直性抽搐、昏迷、呼吸衰竭,发作时全身抽搐、口吐白沫、小便失禁、意识丧失,实验室检查毒鼠强阳性,结合患者的临床表现以及特异性实验室检查,排除其他疾病,毒鼠强中毒诊断成立。本组病例因服毒病史不明确而误诊3例,误诊率高。本文所提5例患者3例死于呼吸衰竭,2例临床治愈。应提请广大临床医生注意人为投毒引起的毒鼠强中毒因病史不清,发病急,特别容易引起患者死亡,要及时确诊、早期洗胃、有效地控制惊厥及二巯基丙磺酸钠的应用。
简介:AbstractBackground:Epithelial to mesenchymal transition (EMT) is a key process in determining distant metastasis and intra-hepatic dissemination of hepatocellular carcinoma (HCC). Follistatin (FST) family members are considered to be an attractive therapeutic targets and prognostic indicators in cancers. As a derivative of FST, Follistatin Like 5 (FSTL5) may play a similar role in HCC cells. This study aimed to investigate the expression and function of FSTL5 in HCC and its role in EMT.Methods:FSTL5, E-cadherin and vimentin in HCC, and paracancerous tissues were detected by immunohistochemistry. Correlation of FSTL5 expression with overall survival was assessed. The proliferation and invasion of HCC cell lines SK-Hep1 and MHCC-LM3 were analyzed by cell counting kit-8 and Transwell assays. The expression of FSTL5, E-cadherin, and vimentin in HCC cells was examined by polymerase chain reaction and Western blot analysis. T-test was used to analyze the difference in proliferation and invasion ability between groups. The Spearman rank correlation test was used to detect the correlation between the expression of FSTL5 and E-cadherin or vimentin.Results:The expression of FSTL5 in HCC was lower than that in paracancerous tissues (9.97% vs. 82.55%, χ2 = 340.15, P < 0.001). Patients with high FSTL5 expression had a better prognosis (χ2= 8.22, P= 0.004) and smaller tumor diameter (χ2 = 45.52, P < 0.001), less lymph node metastasis (χ2 = 5.58, P= 0.02), earlier tumor node metastasis stage (χ2 = 11.29, P= 0.001), a reduced number of tumors (χ2 = 5.05, P= 0.02), lower alpha-fetoprotein value (χ2 = 24.36, P < 0.001), more probability of hepatitis carrying (χ2 = 40.9, P < 0.001), and better liver function grade (χ2 = 5.21, P = 0.02). Immunohistochemistry showed that FSTL5 expression in HCC tissues was positively correlated with E-cadherin expression (r = 0.38, P < 0.001) and negatively correlated with vimentin expression (r = -0.385, P < 0.001). Furthermore, over-expression of FSTL5 up-regulated the expression of E-cadherin and down-regulated the expression of vimentin in SK-Hep1 (negative control [NC] vs. FSTL5-interfering group [Lv-FSTL5]: E-cadherin [t= 45.03, P < 0.001], vimentin [t= 67, P < 0.001]) and MHCC-LM3 (NC vs. Lv-FSTL5: E-cadherin [t = 50, P < 0.001], vimentin [t = 72.75, P < 0.001]) cells at mRNA level. The same as protein level. In addition, the over-expression of FSTL5 inhibited the proliferation (NC vs. Lv-FSTL5: SK-Hep1, 3 d [t = 7.324, P = 0.018], 4 d [t = 6.23, P = 0.021], 5 d [t= 10.21, P= 0.003]; MHCC-LM3, 3 d [t= 4.32, P= 0.037], 4 d [t= 7.49, P= 0.012], 5 d [t= 9.3661, P = 0.009]) and invasion (NC vs. Lv-FSTL5: SK-Hep1, t= 21.57, P < 0.001; MHCC-LM3, t= 18.04, P < 0.001) of HCC cells.Conclusions:Down-regulation of FSTL5 may contribute to EMT of HCC, and FSTL5 is a potential target in the treatment of HCC.
简介:摘要目的探讨宫颈妊娠减少大出血的治疗和预后。方法对我院5年来宫颈妊娠5例患者的临床资料进行回顾分析。结果宫颈妊娠出现多量阴道流血或清宫后阴道流血多者,应尽早双侧骼内动脉栓塞术,成功的保留了患者的子宫,免于术后的创伤。结论宫颈妊娠出现多量阴道流血,及早运用氨甲碟砱(MTX)合双侧骼内动脉栓塞术(WSA)治疗,可以降低子宫切除及死亡率。
简介:摘要姐妹染色单体凝聚发生于DNA复制时期,由黏合素调节,并且依赖于细胞分裂周期相关蛋白5(CDCA5)及黏合素的乙酰化。WAPL可以促进黏合素与DNA解离,CDCA5可以拮抗WAPL的作用,通过稳定黏合素与DNA的结合从而稳定姐妹染色单体凝聚。CDCA5 mRNA在多种肿瘤细胞株中具有较高的转录水平,提示CDCA5可能与肿瘤细胞较高的恶性增殖活性有关,并且已经在肝癌、肺癌等多种肿瘤中得到证实,CDCA5可能是肿瘤治疗的潜在靶向分子。
简介:摘要目的总结儿童声门下囊肿的临床特征及诊疗经验。方法对2018年4月至2019年6月山东大学齐鲁儿童医院确诊的5例声门下囊肿患儿的临床资料进行回顾性分析。结果5例患儿中2例为早产儿,3例为足月儿,均有气管插管史。1例一直无症状,其余4例有喉鸣,其中2例伴声嘶、呼吸困难,曾被误诊为喉软化症、喉炎等。支气管镜检查见声门下灰白色囊肿样病变,增强CT检查为低密度区,无强化。均给予激光及钳夹治疗,术后随访支气管镜5~12周,均无复发及声门下狭窄。结论有气管插管史的患儿出现喉鸣应及时行支气管镜检查明确有无声门下囊肿,经支气管镜激光治疗是声门下囊肿的有效治疗方法。
