作者： Wei-Hsian Yin Chin-Kun Tseng Tien-Ping Tsao Hsu-Lung Jen Wen-Pin Huang Chien-Lung Huang Jiann-Jong Wang mason shing young Division of Cardiology Heart Center Cheng Hsin General Hospital Taipei Taiwan China Faculty of Medicine National Yang-Ming University Taipei Taiwan China Institute of Clinical Medicine National Yang-Ming University Taipei Taiwan China Cardiovascular Research Centre School of Medicine National Yang-Ming University Taipei Taiwan China

Background Although radial access for drug-eluting stent （DES） combined with rotational atherectomy （RA） in patients with calcified coronary lesions may be associated with a lower risk of major bleeding complications and obtain favorable clinical results compared with femoral access, the long-term outcome data of this approach were limited in contemporary DES era. Methods ＆ Results This retrospective study sought to compare in-hospital and long-term outcomes for patients undergoing RA via the transradial （TR） and transfemoral （TF） route in 126 consecutive patients （59 radial, 67 femoral） from 2009 to 2014. TR RA procedures were performed in 44/62 （71%） by the three TR operators, compared with 15/64 （23%） by the four TF operators in the present study. Significantly smaller diameter guide catheters and burrs （1.39 ± 0.16 mm vs. 1.53 ± 0.24 mm, P = 0.001） were used in the TR group. Procedural success rates were similar in both TR and TF groups. There was a significantly less major access site bleeding complications in favor of radial artery access （2% vs. 16%, P = 0.012）. The incidence of in-hospital death or myocardial infarction was low in both groups. Although a trend of lower adverse event rate was demonstrated in the TR group compared with the TF one, no statistical significance （21% vs. 27%, P = 0.135） was detected. Conclusions Radial access, a useful alternative to femoral access for RA and DES, can be safely and successfully performed on up to 71% of the patients with heavily calcified coronary lesions needing RA by experienced TR operators.

Benign nontraumatic inflammatory stricture of the common bile duct (CBD) may result in obstructive jaundice, which can be misdiagnosed as a malignant tumor of the CBD preoperatively. Two cases with strictures of the mid portion of the common bile duct presenting with obstructive jaundice are reported herein. Preoperative radiological studies prompted us to confidently make the diagnosis of cholangiocarcinoma. However, the postoperative diagnosis on histological examination of the resected lesions was chronic inflammation and fibrosis. The complications of chronic duodenal ulcer are considered as the etiology of these two disorders.

在18世纪到19世纪的200年间,欧洲人才辈出,诞生的大数学家数不胜数。这期间,东方的数学却反常地沉寂。在明治维新以前,日本的数学成就远不如中国;但到了19世纪末,中国的数学反而不如日本。通过比较从明治维新到二战前后中日数学人才的培养,分析了中国这期间数学落后于日本和世界的原因。日本政府明治维新要求老百姓全面向西方学习乃原因之一,而中国人由于坚持"中学为体,西学为用"的信念,因而在追求真理的态度上始终不能全面以赴,也不失数学及其他科学落伍的重要原因。此外,中国早期学习西方以应用科技为主,缺乏对数学的热情,一直到20世纪20年代还没有认识到当代最先进的数学,始终未接触到学问的前沿。另外,日本数学的迅速兴起与其学习方法有密切的关系。没有做学问的热情,没有崇高的志愿,不可能产生杰出的数学家。今日中国数学的前途,端赖于年轻一代数学家的培养,研究生的培养则溯源于中学生的教育。期望重新燃烧起中国人对数学的热情。

Cardiac ryanodine receptor gene(hRyR2) mutation underlying catecholaminergic polymorphic ventricular tachycardia in a Chinese adolescent presenting with sudden cardiac arrest and cardiac syncope

引用

Chinese Medical Journal 2006年第24期119卷 2129-2133页

Sudden cardiac death （SCD） in children and adolescents is uncommon and yet it is devastating for both victim＇s family and the society. Recently, it was increasingly recognized that SCD in young patients with structurally normal heart may be caused by inheritable primary electrical diseases due to the malfunction of cardiac ion channels, a disease entity known as the ion channelopathies. Catecholaminergic polymorphic ventricular tachycardia （CPVT） is a specific form of ion channelopathy which can cause cardiac syncope or SCD in young patients by producing catecholamine-induced bi-directional ventricular tachycardia （BiVT）, polymorphic VT and ventricular fibrillation （VF） during physical exertion or emotion. We reported here an index case of CPVT caused by cardiac ryanodine receptor gene （hRyR2） mutation which presented as cardiac syncope and sudden cardiac arrest in a Chinese adolescent female.

Gastric cancer(GC) is a highly heterogeneous disease with multiple cellular types and poor ***, the cellular evolution and molecular basis of GC at the individual intra-tumor level has not been well demonstrated. We performed single-cell whole exome sequencing to detect somatic singlenucleotide variants(SNVs) and significantly mutated genes(SMGs) among 34 tumor cells and 9 normal cells from a patient with GC. The Complete Prediction for Protein Conformation(CPPC) approach directly predicting the folding conformation of the protein 3D structure with Protein Folding Shape Code, combined with functional experiments were used to confirm the characterization of mutated SMGs in GC cells. We identified 201 somatic SNVs, including 117 non-synonymous mutations in GC cells. Further analysis identified 24 significant mutated genes(SMGs) in single cells, for which a single amino acid change might affect protein conformation. Among them, two genes(CDC27 and FLG) that were mutated only in single cells but not in the corresponding tumor tissue, were recurrently present in another GC tissue cohort, and may play a potential role to promote carcinogenesis, as confirmed by functional characterization. Our findings showed a mutational landscape of GC at intra-tumor level for the first time and provided opportunities for understanding the heterogeneity and individualized target therapy for this disease.

本研究目的是分析香港市民和注册护士对预前指示的态度和使用时所考虑的因素,及他们对垂死病患者采用维持生命治疗的看法。结果显示年龄和学历高的受访者普遍接受预前指示,市民和护士的看法不同。预前指示普及已是社会的趋势,但现时社会预前指示的理解如维持生命治疗的决策过程仍模糊不清,唯医护人员的理解较深。因此,医护人员对预前指示这一概念的推广和教育上应兼付什么责任的问题值得思考。
