Emergency splenic arterial embolization for massive variceal bleeding in liver recipient with left-sided portal hypertension.

Splenic vein thrombosis with gastric variceal bleeding is difficult to manage, and splenectomy may be necessary to stop variceal bleeding. The authors report the case of a post-orthotopic liver transplant patient with bleeding gastric varices secondary to splenic vein thrombosis treated by partial splenic artery embolization. Successful embolization was performed via transcatheter approach depositing Gianturco coils into the intrasplenic artery resulting in immediate cessation of variceal bleeding. No recurrence of bleeding was noted postembolization. In conclusion, splenic artery embolization can be used as treatment for postliver transplant variceal bleeding with hypersplenism.     

PET/CT在胰头肿块型良恶性病变的鉴别诊断和在术前评估胰腺癌切除的可行性

目的 1、探讨PET/CT在胰腺癌与肿块型胰腺良病史鉴别诊断方面的价值。2、PET/CT对胰腺癌可行性切除评估中的价值。3、PET/CT在发现淋巴结转移,神经束膜侵犯和远处转移方面的价值。方法本文对37例经B超、CT、内镜等检查发现胰头占位但未能明确肿块性质的患者进行PET/CT扫描。收集病灶的大小、部位,局部和远处淋巴结转移状况,神经束膜侵犯情况,病变与邻近组织器官的解剖学关系以及是否出现远处转移病灶等情况;测量肿瘤大小及面积,病灶的18FSG早期最大标准化摄取值（SUVmax）。结果 24例术前考虑胰腺癌患者早期SUVmax平均值为6.38±3.84;肿瘤的大小平均3.40cm×2.64cm,假阳性4例;慢性胰腺炎7例早期SUVmax平均值为3.30±2.27;肿瘤的大小平均3.7cm×2.5cm。2例壶腹部癌患者SUVmax分别是5.4和4.2,肿瘤大小分别是：4.2cm×3.8cm和2.7cm×1.9cm;2例胰腺粘液性囊腺瘤,SUVmax分别是：0.6和0.8,肿瘤大小分别是：3.8cm×2.5cm和5.4cm×2.7cm。1例胰腺实性-假乳头状瘤,SUVmax值为6.9,肿瘤大小为6.6×4.7cm。1例十二指肠乳头癌,其SUVmax为6.9,肿瘤大小1.7cm×1.4cm。以早期SUVmax等于3.0作为胰腺良恶性病变的鉴别阈值,PET/CT诊断胰腺癌敏感度、特异性和准确性分别为87.1%（27/31例）、83.3%（5/6例）、86.5%（32/37）。PET/CT发现5例胰腺癌存在远处转移而无法施行手术治疗。结论 PET/CT显像诊断胰腺癌灵敏度、特异性以及准确性较高,在胰头癌和肿块型慢性胰腺炎的鉴别诊断中具有显著意义,并在术前胰腺癌可切除性评估起到指导性意义。

A cross-sectional study of obstructive sleep apnea in patients with colorectal cancer

BackgroundThe association between colorectal cancer (CRC) and obstructive sleep apnoea (OSA) has been attracting increasing attention. several studies had confirmed that OSA increases the risk of CRC onset. However, the findings of studies on the morbidity of OSA in patients with CRC were unclear. Therefore, this study aimed to investigate the morbidity of OSA in patients with CRC as well as the association between the clinicopathological characteristics of OSA and CRC.MethodsA total of 414 patients with a pathological diagnosis of CRC from 1 January, 2020 to 30 December, 2020 were included in this study. Demographic characteristics, clinical information, and tumor characteristics of participants were collected; sleep was monitored using a wearable oximeter and via sleep quality questionnaire. The oxygen desaturation index (ODI) was used to classify OSA severity so that the diagnostic criteria for OSA were set based on the ODI as 0–5 (normal) and ≥5 (abnormal). After correcting for confounding factors, a logistic regression analysis was performed to calculate the odds ratio (OR) and 95% confidence interval (CI) for the factors affecting the tumor lymph node stage (N stage).ResultsA total of 402 patients with CRC were included in this study, including 225 (55.97%) men and 177 (44.03%) women. The mean ODI value of participants was 3.40±8.17. The morbidity of OSA among the patients with CRC having ODI ≥5 was 16.17%. A comparison between the normal and abnormal ODI value groups revealed that the high proportion of abnormal ODI was related to higher N stage (P<0.05). Logistic regression analysis revealed a correlation of ODI values and age to the N stage. Specifically, CRC patients with an abnormal ODI had a higher risk of lymph node metastasis compared to those with normal ODI (OR =1.915, 95% CI: 1.025 to 3.579). Moreover, patients with CRC aged ≥65 years had a higher risk of lymph node metastasis compared to those aged <65 years (OR =2.190, 95% CI: 1.163 to 4.125).ConclusionsCRC patients with abnormal ODI are susceptible to OSA. Additionally, abnormal ODI and age ≥65 years are relevant factors for the N2 stage.     

银杏叶提取物与去铁胺合用防治顺铂耳毒性实验研究

目的银杏叶提取物-金纳多(extract of Ginkgo Biloba leaves injection,EGb)和铁螯合剂-去铁胺(Deferoxamine,DFO)联合应用对抗顺铂(Cisplatin,CDDP)耳毒性的作用。方法将豚鼠随机分为CDDP组、EGb组、DFO组、EGb+DFO组及对照组,测定听性脑千反应(auditory brain—stem response,ABR)、血清超氧化物歧化酶(superoxide dismutase,SOD)活性和丙二醛(MDA)含量及应用光镜、及扫描电镜技术,观察用药前后各指标的变化。结果CDDP组动物ABR阈值较其他各组明显升高(P<0．01),其余各组间差异不显著(P>0．05)。血清SOD活性和MDA含量检测表明,CDDP组血清SOD活性较对照组明显降低(P<0．01),MDA含量显著升高(P<0．01),其他组较对照组则差异无显著性(P>0．05)。耳蜗扫描电镜显示EGb+DFO组和DFO组比CDDP组毛细胞受损程度明显为轻,EGb组较CDDP组毛细胞受损程度略微减轻。结论DFO与EGb合用,可有效减轻CDDP的耳毒性作用,其效果优于单独应用EGb,与单独应用DFO效果相当,二者合用还可能减轻顺铂的骨髓抑制副作用。结果提示铁离子参与的自由基反应可能是顺铂耳毒性机制之一。

血清斯钙素⁃1在稳定期慢性阻塞性肺病中的表达及意义

目的：探讨斯钙素?1（stanniocalcin?1,STC1）在稳定期慢性阻塞性肺病（chronic obstructive pulmonary disease,COPD）患者血清中的表达及意义。方法：收集55例稳定期COPD患者,根据肺功能和问卷评分进行相应分组,且以24例健康者作为对照。采用酶联免疫吸附法（ELISA）测定各研究对象的血清斯钙素?1表达情况,进行相关分析。结果：①与健康对照组相比,稳定期COPD患者血清斯钙素?1表达水平明显降低（P < 0.05）。②血清斯钙素?1在初筛COPD上具有一定价值（P=0.025,AUC=0.659）,最佳阈值为1 350 pg/mL（敏感度81.82%;特异度50.00%）。③血清斯钙素?1与稳定期COPD患者病情严重程度［包括GOLD分级、慢阻肺评估测试（COPD assessment test,CAT）评分、ABCD分组、肺功能］无明显相关性。结论：血清斯钙素?1在COPD中显著降低,可能对于COPD的诊治具有一定临床意义。
