Successful Use of Surgically Placed Impella 5.0 and Central Extracorporeal Membrane Oxygenation Circuit in a Patient with Postcardiotomy Shock

The Impella 5.0, a percutaneously inserted left ventricular assist device, has been used to support patients who have severe heart failure or who are undergoing high-risk percutaneous coronary intervention. We report our surgical placement of the Impella 5.0, through a graft sewn to the aorta, to unload the left ventricle of a 59-year-old man who was undergoing venoarterial extracorporeal membrane oxygenation for postcardiotomy shock. The patient underwent successful placement of a long-term left ventricular assist device before his discharge from the hospital. The versatility of the Impella 5.0 is exemplified in this patient who was successfully bridged to long-term support.     

我国东部地区结节性痒疹患者中医体质类型分布规律

目的探讨我国东部地区结节性痒疹患者中医体质类型的分布特点。方法采用病例对照设计方法,选取120例结节性痒疹患者作为病例组,120例健康体检者作为对照组,参照《中医体质分类与判定表》进行中医体质类型调查,分析其分布规律。结果结节性痒疹患者年龄(41.58±16.27)岁,性别男女比例约1∶1.2,体质类型分布前四位的是湿热质23例、血瘀质20例、气郁质19例、特禀质13例;健康体检者体质类型分布前四位的是平和质33例、气虚质19例、阳虚质14例、痰湿质13例;与对照组相比,病例组偏颇体质明显增多(P<0.01),2组体质构成比亦有显著性差异(P<0.01),其中湿热质、气郁质、血瘀质、特禀质较对照组转化分增加(P<0.05)。结论结节性痒疹的发病与湿热质、血瘀质、气郁质、特禀质偏颇体质类型密切相关。     

HER2-positive advanced breast cancer treatment in 2020

HER2-positive breast cancer is an aggressive subtype identified in the 1980s. The development of therapies targeting the HER2 has improved outcomes. The current standard of care, established in 2012 is dual blockade with trastuzumab + pertuzumab as first-line followed by TDM-1 as second-line. Several suboptimal choices are available in third-line or more. In 2019 the presentation of several trials evaluating new drugs and regimens in third-line has re-opened questions about sequencing, treatment of triple positive disease and treatment choice after exposure to TDM-1. These include tucatinib, neratinib and trastuzumab-deruxtecan. Other agents – including other antibody drug conjugates and bispecific antibodies as well as combinations - will lead to further changes in coming years. Additionally, should the numerous putative biomarkers thus identified ever come into use at the clinic, choice of treatment and response evaluation may be substantially changed.     

顾锡镇教授从脾肾论治肌萎缩侧索硬化症经验

肌萎缩侧索硬化症是一种病因不清的致死性神经系统罕见病，临床表现为进行性加重的肌无力、肌肉萎缩及延髓麻痹，最终累及呼吸肌致呼吸衰竭而死亡。顾锡镇教授从脾肾论治，运用健脾补肾法治疗该病在延缓疾病进展与改善生活质量方面取得了一定疗效。文章总结了顾教授辨治肌萎缩侧索硬化症的临床经验，并例举1个典型医案加以佐证。     

自噬在前列腺癌发生发展和治疗中的研究进展

自噬是真核细胞通过溶酶体对其自身生物大分子和细胞器回收再利用的过程，其在维持细胞稳态中发挥重要作用，并参与多种病理生理过程。在肿瘤的发病过程中，自噬发挥“双面作用”，既可以抗癌也能促癌。前列腺癌是老年男性最常见的恶性肿瘤，研究表明前列腺癌的发生发展与自噬作用密切相关，放化疗、内分泌治疗等对肿瘤细胞造成的应激可通过自噬得以缓解，抵抗治疗，因而自噬抑制剂对于放化疗等具有协同促进作用。本文就自噬在前列腺癌中发病和治疗进行综述，以期为前列腺癌的诊治提供一些新的思路。     

Tratamiento empírico de la oligoastenoteratozoospermia idiopática

Male infertility accounts for 50% of the causes of infertile couples, being more than 30% of unknown etiology. In these cases, empiric treatment can be an option prior to the application of assisted reproduction techniques. Empiric treatment can be categorized as hormonal, such as gonadotropins, antiestrogens and aromatase inhibitors, and antioxidant, with vitamins, trace elements and carnitine, among others. Although scientifically acceptable evidence is limited due to the absence of large randomized and controlled clinical trials, recent systematic reviews and meta-analyses show that treatment with gonadotropins, antiestrogens and antioxidants increases pregnancy and live birth rates and improves seminal parameters. Empiric medical treatment for idiopathic infertility can be considered in specific cases in order to improve semen quality and spontaneous fertility.     

Analysis of Progression Patterns and Failure Sites of Patients With Metastatic Lung Adenocarcinoma With EGFR Mutations Receiving First-line Treatment of Tyrosine Kinase Inhibitors

BackgroundReliable prediction of progression patterns and failure sites for patients with stage IV lung adenocarcinoma is valuable for physicians to deliver personalized tyrosine kinase inhibitor (TKI) treatment.Patients and MethodsWe retrospectively enrolled 266 patients who had stage IV lung adenocarcinoma and received first-line TKI treatment from 2013 to 2017 in Shanghai Chest Hospital. The clinical characteristics at initial diagnosis, progression patterns, and failure sites were analyzed with the attempt to identify some predictive factors for progression patterns and failure sites.ResultsAmong all patients, 62.4% developed systemic progression, and 37.6% developed oligoprogression. Both cohorts had a median progression-free survival (PFS) of 9 months. The percentage of patients who developed original and distant failure was 39.1% and 60.9%, respectively. Patients with oligometastasis at initial diagnosis were more prone to develop oligoprogression (odds ratio [OR], 4.370; 95% confidence interval [CI], 1.881-10.151; P = .001), whereas pulmonary metastasis was negatively correlated with oligoprogression (OR, 0.567; 95% CI, 0.330-0.974; P = .04). Both oligometastasis diagnosis (OR, 2.959; 95% CI, 1.347-6.500; P = .007) and the maximum diameter of the primary lung lesion (threshold 3.25 cm: OR, 3.646; 95% CI, 2.041-6.515; P = .0001) were strong predictive factors for original failures. Osseous metastasis at initial diagnosis might be an indication for distant failure (OR, 0.536; 95% CI, 0.316-0.909; P = .021).ConclusionOver one-half of patients with stage IV lung adenocarcinoma receiving first-line TKI treatment developed systemic progression and distant failure. Metastasis patterns at initial diagnosis was the most important predictive factor for progression patterns and failure sites. The maximum diameter of the primary lung lesion and evidence of osseous metastasis were also found to be significant indicative factors for failure sites.
