目的研究Ets-1、基质金属蛋白酶1(MMP-1)及基质金属蛋白酶1抑制物(TIMP-1)在膀胱移行细胞癌(BTCC)中的表达及意义。方法用免疫组化方法检测40例BTCC组织和12例正常膀胱黏膜组织中Ets-1、MMP-1及TIMP-1的表达;分析Ets-1与BTCC临床病理特征间的关系;研究BTCC中MMP-1、TIMP-1表达与Ets-1表达的相关性。结果①Ets-1在BTCC中高度表达,阳性率为82.5%(P<0.01),且随BTCC临床分期和病理分级的升高而增加,肿瘤复发组高于无复发组,肿瘤转移组高于无转移组(P<0.05)。②MMP-1阳性表达率膀胱癌组(85.0%)明显高于对照组(58.3%)(p<0.05);TIMP-1阳性表达率对照组(83.3%)明显高于膀胱癌组(47.5%)(P<0.05)。③MMP-1与Ets-1表达呈正相关(Rs为0.824,P<0.01),而TIMP-1与Ets-1表达呈负相关(Rs为-0.821,P<0.01)。结论①Ets-1在BTCC中高度表达,并随BTCC分期分级升高而增加;Ets-1与BTCC转移及复发密切相关。②BTCC中Ets-1上调MMP-1表达,而下调TIMP-1表达,从而参与BTCC侵袭与转移。     

热性惊厥患儿血清褪黑素水平和细胞免疫功能的变化及其临床意义

Objective To investigate the changes of melatonin and cellular immunological function in children with febrile seizures and its clinical significance. Methods 50 children, including 23 cases with complex febrile seizure (CFS) and 27 cases with simple febrile seizure (SFS) , and 25 cases with upper respiratory infections children selected as control group were enrolled in this study. Serum melato- nin was measured by enzyme-linked immunosorbent assay (ELISA) and cellular immunological function was measured by flow eytomcter. Results The levels of serum melatonin in the 3 groups of CFS, SFS, control were(14. 91±2. 61) ng/L, (20. 72±2. 54) ng/L, (23.93± 2. Ol) ng/L, respectively. The melatonin levels in CFS children were significantly decreased than that in control group and SFS children (P <0. O1). CD3 + ,CD4 +, the ratio of CD4 + /CD8 + and CD8 + in CFS group were significantly decreased than that in control group and SFS group (P <0.01). The ratio of CD4 +/CD8 + in SFS group was significantly decreased than that in control group (P <0.05), but CD3 + ,CD4 + and CD8 + had no statistics significance among these groups(P >0. 05). The serum rnelatonin level were positive related withdecreaseddegreeofCD3+,CD4+ andtberatioofCD4+ /CDS+ (r≥0. 472, P <0.05). Conclusion The disorder cfcellular immunological function was possible related with the loss of serum melatonin, and the loss of serum melatonin maybe one of the reasons for febrile seizures relapse and brain injured.

目的:通过观察妇宝胶囊对动物出凝血时间、血液凝固系统的影响,探讨妇宝胶囊的止血机制。方法:采用毛细玻璃管法测定小鼠凝血时间(CT),用断尾法测定出血时间(BT);用ACL-200型血液凝集仪测定大鼠凝血酶原时间(PT)和部分凝血活酶时间(APTT)。结果:妇宝胶囊能明显缩短小鼠CT、BT,缩短大鼠PT和APTT。结论:妇宝胶囊的止血机制主要通过促进内源性和外源性凝血系统,抑制纤维蛋白溶解系统达到目的。     

Polo-like kinase 1 inhibitors in mono- and combination therapies: a new strategy for treating malignancies

Polo-like kinase 1 (Plk1) inhibitors belong to a new class of drugs for the treatment of malignant diseases. They selectively act against a target (Plk1) which is involved in different stages of mitosis such as centrosome maturation, spindle formation, chromosome separation and cytokinesis. Because Plk1 is mainly expressed in proliferating tissues and overexpressed in cancers, its inhibition is potentially less prone to toxicities associated with current antimitotic agents, which also act on nondividing cells. Several Plk1 inhibitors are being evaluated as cancer treatment drugs. Based on the essential role of Plk1 during mitosis, Plk1 inhibitors target all rapidly dividing cells irrespective of their tumor suppressor or oncogene mutations. In this article, their mechanisms of action, efficacy and toxicity profile are discussed.

Investigational therapies targeting CD37 for the treatment of B-cell lymphoid malignancies

Introduction: While chemotherapy still remains a cornerstone of oncologic therapy, immunotherapy with monoclonal antibodies has steadily improved the treatment strategy for several hematologic malignancies. New treatment options need to be developed for relapsed and refractory non-Hodgkin lymphoma (NHL) patients. Currently, novel agents targeting specific molecules on the surface of lymphoma cells, such as anti-CD37 antibodies, are under considerable investigation. Here we report on anti-CD37 targeting for the treatment of patients with B-cell NHL.

Areas covered: CD37 seems to be the perfect therapeutic target in patients with NHL. The CD37 antigen is abundantly expressed in B-cells, but is absent on normal stem cells and plasma cells. It is hoped that anti-CD37 monoclonal antibodies will increase the efficacy and reduce toxicity in patients with both newly diagnosed and relapsed and refractory disease. Recent clinical trials have shown promising outcomes for these agents, administered both as monotherapy and in combination with standard chemotherapeutics.

Expert opinion: The development of new therapeutic options might help to avoid cytotoxic chemotherapy entirely in some clinical settings. This article presents the latest state of the art on the new treatment strategies in NHL patients. It also discusses recently approved agents and available clinical trial data.
