多项指标联合检测在原发性肝癌诊断中的应用

目的探讨甲胎蛋白（AFP）、癌胚抗原（CEA）、糖链蛋白199（CA199）、α—L-岩藻苷酶（AFU）、γ-谷氨酰转移酶（γ-GT）等多项指标联合检测对原发性肝癌早期诊断的临床应用价值。方法采用化学发光法检测AFP、CEA和CA199;采用速率法检测AFU;用酶法检测γ-GT。结果单项AFP、CEA、CA199、AFU、γ-GT的血清水平原发性肝癌组与健康对照组比较差异有统计学意义（P〈0．05）;单项AFP、CEA、CA199、AFU、γ—GT的血清水平原发性肝癌组与肝炎肝硬化组比较差异有统计学意义（P〈0．01）。AFP、CEA、CA199、AFU、γ-GT等多项指标联合检测对原发性肝癌诊断阳性率达94．12％．显著高于单项AFP阳性率68．62％（P〈0．01）。结论AFP、CEA、CA199、AFU、γ-GT等多项指标联合检测可提高原发性肝癌早期诊断阳性检出率,特别是单项AFP检测阴性的肝癌患者的诊断具有重要临床实用价值和临床推广价值。     

原发闭经表型的细胞遗传学病因研究

目的:探讨原发闭经表型的细胞遗传学病因。方法:运用常规的染色体核型分析技术及FISH、C-带和Q-带技术,分析25例原发闭经表型患者的染色体核型。结果:25例原发闭经表型病例中,18例核型异常,占72.0%。异常核型病例分别为:45,X 8例、46,XY 2例,等臂X 1例、嵌合核型4例(分别为45,X细胞系与不同的结构异常性染色体细胞系的嵌合体)、X长臂末端缺失1例、X-常染色体平衡易位2例。除这18例异常核型患者外,尚有7例为先天性无子宫、无阴道的原发闭经患者未检出核型异常。结论:X染色体数目单体、X结构异常、X染色体数目单体细胞系与结构异常性染色体细胞系的嵌合体核型、XY性发育异常(DSD)、X-常染色体平衡易位都可导致原发闭经表型。常规G-显带技术与C-带、Q-带技术及FISH技术相互结合,有助于进一步准确诊断核型。     

Mental health and primary dysmenorrhea: a systematic review

Several factors including demographic, reproductive, lifestyle, psychological and social factors can affect incidence and severity of primary dysmenorrhea. This study aimed to systematically review the psychological risk factors associated with primary dysmenorrhea. Embase, ISI web of knowledge, ProQuest, Science Direct, Scopus and PubMed central were searched using keywords related to risk factors and primary dysmenorrhea. Observational studies, published in English after 2000, focusing solely on psychological factors affecting primary dysmenorrhea were included. The search process retrieved 11,928 potential related articles. Thirty three articles met inclusion criteria and were assessed for final synthesis. The STROBE checklist was used to quality assessment of studies. Results of study showed that few studies had investigated relationship between dysmenorrhea and most psychological disorders. Most studies have investigated the relationship between dysmenorrhea and depression, anxiety, stress, alcohol abuse and somatic disorders. So, further studies are needed to investigate relation between most psychological disorders with primary dysmenorrhea. Significant relationship between some mental health components such as depression, anxiety and stress with primary dysmenorrhea shows the importance of psychological assessment before the choice of therapeutic methods. Also, the feasibility of designing and evaluating the effectiveness of the use of psychotherapy interventions for the treatment of primary dysmenorrhea as alternative therapies can be considered.     

基层医院56例早期胃癌胃镜下表现的分析

目的探讨早期胃癌(EGC)普通胃镜下的表现,为提高基层医院EGC的检出率提供参考。方法回顾性分析我院确诊的早期胃癌56例患者的内镜下表现,包括发生部位、大小、分型及各型表现以及亚甲蓝着色特征。结果 56例患者中,病灶位于胃窦部22例(39.3%),胃体部18例(32.1%),胃角部10例(17.9%),贲门部6例(10.7%)。单个病灶直径为0.5~2.6 cm,平均(1.28±1.36)cm。Ⅰ型(隆起型)12例(21.4%),Ⅱ型(平坦型)36例(64.3%),其中Ⅱa型(浅表隆起型)10例(17.9%),Ⅱb型(浅表平坦型)2例(3.6%),Ⅱc型(浅表凹陷型)24例(42.9%),Ⅲ型(溃疡型)2例(3.6%)。56例患者经亚甲蓝染色后,病变黏膜呈黑色或深蓝色48例(85.7%),浅蓝色6例(10.7%),不着色2例(3.6%)。结论 EGC好发于胃窦部,以Ⅱc型为主,多数病变亚甲蓝染色呈深蓝色。     

Two-step transplantation for primary hyperoxaluria: Cadaveric liver followed by living donor related kidney transplantation

Abstract:  In PH, PLTX, although ideal in theory, is rarely achieved. Patients usually have reached end-stage kidney disease while requiring combined liver and kidney transplantation. In this combined procedure, the sudden high oxalates mobilization from blood and tissue stores jeopardizes the success of the kidney graft, with a high risk of post-transplant early kidney necrosis or chronic graft damage. Here, we report the case of a three-yr-old girl with PH and ESRF in whom we performed sequentially deceased donor liver transplantation followed four months later by living donor kidney transplant, after normalization of blood oxalate levels and improvement of urinary oxalate output. After this two-step transplantation, our patient showed normalization of renal function with good urinary output and maintained normal blood oxalate levels. This strategy seems to be a reasonable approach in order to avoid acute renal tubular injury because of oxalate excretion in these patients.

Genetic modification of primary chronic lymphocytic leukemia cells with a lentivirus expressing CD38

Studies of the role of individual genes in chronic lymphocytic leukemia (CLL) have been hampered by the inability to consistently transfect primary tumor cells. Here, we describe a highly efficient method of genetically modifying primary CLL cells using a VSVG pseudotyped lentiviral vector. We transduced CD38 negative CLL cells with a lentiviral vector encoding CD38 which caused increased surface CD38 expression in all the samples tested (n=17) with no evidence of plasmacytoid differentiation. The mean percentage of positive cells expressing CD38 was 87%±8.5% and the mean cell viability 74%±17%. This high level of transduction of all the CLL cell samples tested demonstrates the utility of this technique which should prove applicable for the introduction and analysis of other genes in these non-dividing cells.     

Nonoperative management of a giant omphalocele using a silver impregnated hydrofiber dressing: a case report

The surgical management of a giant omphalocele is challenging. Many cannot be closed at birth and must initially be managed nonoperatively with a topical agent to facilitate epithelialization. We report the case of a term, 1-day-old female neonate with a giant omphalocele treated initially with a hydrofiber dressing containing silver (Aquacel Ag; ConvaTec Inc, Skillman, NJ) and then with delayed primary closure.     

原发性小肠癌的预后因素分析

目的探讨原发性小肠癌的诊断、治疗方法及其主要预后因素。方法回顾性分析我院1978年-2009年间收治并经病理证实的33例原发性小肠癌的临床资料,所有数据采用Kaplan-Meier法进行生存率分析,利用log-rank检验进行统计学差异性比较,应用Cox比例风险模型进行预后多因素分析。结果除患者的构成和肿瘤的生长部位对生存率无明显影响外,肿瘤分期、病理类型和分化程度以及治疗方法对生存率都有重要影响,P值均0.01,差异具有显著性。结论虽然小肠癌患者的生存率总体较低,但早期诊断并行根治性手术可望改善预后,提高无病生存率,化疗对延长生存率作用不大,其价值有待商榷。
