Coexistence of benign phyllodes tumor and invasive ductal carcinoma in distinct breasts: case report

This report describes a rare case of coexistence of benign phyllodes tumor, which measured 9 cm in the right breast, and invasive ductal carcinoma of 6 cm in the left breast, synchronous and independent, in a 66-year-old patient. The patient underwent a bilateral mastectomy due to the size of both lesions. Such situations are rare and usually refer to the occurrence of ductal or lobular carcinoma in situ when associated with malignant phyllodes tumors, and more often in ipsilateral breast or intra-lesional.     

Balancing Within Various Discourses—The Art of Being Old and Living as a Sami Woman

The aim of this part of the Umeå 85+ Study was to explore how indigenous women narrate their lives and their experience of being old as Sami women. Interviews with 9 old Sami women were analyzed using grounded theory. The categories identified were “reindeer as the basis of life,” “longing for significant Sami values,” “feeling valued as a Sami woman,” and “changing for survival;” these evolved into the core category: “balancing within various discourses—the art of being old and living as a Sami woman.” Knowing how to balance provided the ability to make use of available opportunities.     

肝脏增强CT扫描与MRI在肝癌诊断中的研究价值

目的探讨增强CT扫描与MRI在肝癌诊断中的价值。方法回顾性分析2014年5月至2016年3月在本院进行影像检查并经手术病理确认的60例肝癌患者的临床资料和影像资料,同时对患者癌变部进行归类分析,并通过两种影像检查方法的确诊率来评判两种检查方式的价值。结果60例中,巨块型占总数,结节型占总数54.5%,小肝癌例数占总数30.3%。增强CT对肝癌患者的总检出率为91.2%,MRI对肝癌患者的总检出率为92.3%。两者无明显统计学差异。结论在肝癌的确诊方面,MRI和增强CT扫描均具有较高的精度,可以作进一步推广应用。     

肛门镜压迫下内痔注射法治疗Ⅱ、Ⅲ期内痔的临床疗效

为探讨新型肛门镜压迫下内痔注射法治疗Ⅱ、Ⅲ期内痔的临床疗效,本研究采用多中心随机对照方法,选取200例Ⅱ、Ⅲ期内痔患者分为试验组及对照组,各i00例,试验组采用新型肛门镜压迫下内痔注射法治疗,对照组采用传统消痔灵注射法治疗,观察两组疗效及不良反应。结果显示,试验组治愈84例,好转12例,无效4例,治愈率为84．0％;对照组治愈30例,好转58例,无效12例,治愈率为30．0％。试验组治愈率明显高于对照组,P〈0．01。两组术后第3天出血治愈率差异无统计学意义,P〉0．05;但试验组术后痔核脱出、肛门坠胀治愈率明显高于对照组,P〈0．01。结果表明,肛门镜压迫下内痔注射法治疗Ⅱ、Ⅲ期内痔疗效确切,与传统消痔灵注射法比较,在治疗内痔脱出方面具有更高的临床实用价值。？     

Frequency of blood lactate elevation following esophagectomy and its association to postoperative complications

Background

Esophagectomy is a major surgical intervention and a cornerstone in the treatment of esophageal cancer. There is clinical experience that blood lactate concentration often is elevated in the period following esophagectomy, but the incidence and clinical consequences are sparsely studied.

Methods

We extracted data from all patients undergoing esophagectomy at Karolinska University Hospital 2016–2018, n = 153. Most were performed with minimally invasive technique, n = 130. Blood lactate values directly after surgery, highest value during the first night, and morning level on postoperative day one were recorded. Primary outcome was hospital length of stay and secondary outcome was a composite of postoperative infection, additional surgery, or intensive care during the hospital stay. Development of anastomotic leak was analyzed separately.

Results

Postoperative hyperlactatemia was common as 93% of patients had peak lactate concentration >1.6 mmol/L and 27% >3.5 mmol/L in the first night following operation. Median hospital length of stay was 14 days. Blood lactate showed a weak correlation to hospital stay and intensive care the morning following surgery, but not at arrival to postoperative ward. There were no statistical differences between those with and without anastomotic leak at any of the time points. Elevated lactate in the first 12–16 h postoperatively was related to surgical factors (open technique, surgery time, and perioperative bleeding) but not to patient related factors (ASA-class, Charlson comorbidity index, sex, age) or cumulative fluid balance.

Conclusion

In conclusion, elevated blood lactate in the immediate time following esophagectomy showed a weak association to intensive care and length of stay but not anastomotic leak.     

亚麻子水提液对DPP-4及α-葡萄糖苷酶活性抑制实验研究

目的通过观察亚麻子水提液对二肽基肽酶-4（DPP-4）、α-葡萄糖苷酶抑制作用,为该药防治糖尿病提供实验依据。方法①以DPP-4酶、缓冲液、底物建立DPP-4抑制剂的体外筛选体系,对亚麻子水提液进行抑制实验,采用发色底物法测定吸光度（OD）,计算DPP-4抑制率及IC50值;②以蔗糖为底物建立α-葡萄糖苷酶活性抑制模型,采用葡萄糖氧化酶法测定亚麻子水提液对α-葡萄糖苷酶的抑制作用,计算其抑制率和IC50值。结果①亚麻子具有轻度DPP-4抑制作用,其IC50值738.20mg/L;②亚麻子具有α-葡萄糖苷酶抑制作用,其IC50值为365.9mg/mL。结论亚麻子水提液可一定程度地抑制DPP-4及α-葡萄糖苷酶活性。     

TLIF术式在布氏杆菌性脊柱炎病人中的临床疗效及安全性分析

目的 对比分析单纯后路内固定+一期经腰椎间孔病椎间病灶清除(TLIF)与经典的前后联合手术在布氏杆菌性脊柱炎患者中的临床疗效及安全性。 方法 对我院2015年1月至2017年12月收治的93例布病性脊柱炎患者的临床资料进行分析。按手术方式分为观察组(45例)和对照组(48例)。对两组患者的基础数据、临床指标、术前术后各项指标水平以及术后并发症、植骨治愈情况。 结果 观察组与对照组基础数据比较,差异无统计学意义(P>0.05)。观察组患者的手术时间、住院天数、术中出血量及术后下床时间均明显低于对照组(P<0.01)。两组患者术后3个月的ODI、VAS、CRP、ESR及Cobb角均明显低于术前(P<0.05);术后3个月,观察组患者的ODI、VAS、CRP、ESR及Cobb角均明显低于对照组(P<0.05)。观察组术后并发症发生率(4.4%)明显低于对照组(25.0%)(Χ²=7.674,P<0.01)。 结论 TLIF治疗布氏杆菌性脊柱炎患者的临床疗效突出,安全性较好,更有利于患者术后身体的恢复。
