乳腺癌肿瘤血管生成的临床病理学意义

肿瘤血管生成（ＴｕｍｏｒＡｎｇｉｏｇｅｎｅｓｉｓ，ＴＡ）是目前肿瘤研究的重要课题，其研究目的在于探讨ＴＡ的预后价值以及预测肿瘤对抗血管生成药物的反应。本文应用第八因子相关抗原多克隆抗体对６５例乳腺浸润性导管癌（以下简称乳腺癌）进行了微血管的定量研究。结果显示：腋下淋巴结阳性病例组织的微血管密度（ＭｉｃｒｏｖｅｓｓｅｌＤｅｎｓｉｔｙ，ＭＶＤ）（１２９．７±４４．９）明显高于腋下淋巴结阴性（ＮｏｄｅＮｅｇａｔｉｖｅＢｒｅａｓｔＣａｎｃｅｒ，ＮＮＢＣ）病例组的ＭＶＤ（７９．６±３３．６），差异呈极显著性（Ｐ＜０．００１）；发生术后复发及远处转移的病例的ＭＶＤ均值高达１４５．３；以上结果提示乳腺癌ＭＶＤ与肿瘤转移、复发均密切相关。我们认为乳腺癌ＭＶＤ可反映其血供状态，ＭＶＤ高的病例微血管丰富，肿瘤组织生长快，癌细胞易于进入微循环而发生转移     

急性白血病中c-kil受体表达与染色体异常核型的关系

目的 检测c-kit R在急性白血病（acute leukemia，AL）的表达并进一步分析ANLL中c-kit R表达与染色体异常核型的关系及其意义。方法 采用流式细胞术（flow cytometry，FCM）分别检测并比较92例急性淋巴细胞性白血病（ALL）和81例ANLL初诊患者骨髓单个核细胞（BMMNC）跨膜c-kit R表达的阳性率及阳性水平，并设立20例正常人骨髓标本作为阴性对照组；采用R带显带方法对c-kit R阳性表达的ANLL进行染色体核型分析。结果 ALL患者的c-kit R表达的阳性率及阳性水平与正常人相比差异无显著性（P〉0．05）。ANLL患者的c-kit R表达率及阳性水平则均明显高于正常人和ALL患者（P值分别〈0.01）。ANLL中c-kit R阳性表达者异常核型的百分率为74．1％，明显高于c-kit R阴性组者（26．1％）（P〈0.05）。异常核型的类型有5q-、-17、＋21、del3p、t（8；21）、6p＋、t（1；8）、复杂易位、t（15；17）、t（1；12）、-7、四倍体、20q-等十余种类型。结论 c-kit R可作为髓系免疫学标记，用以协助ANLL的诊断。c-kit R阳性者伴有细胞遗传学异常，但是，c-kit R阳性与染色体异常核型的类型之间不存在特殊对应关系。c-kit原癌基因不是ANLL发病机制的唯一要素。

Grape seed powder increases gastrointestinal motility

Grape seed is an important natural bioactive product with various health benefits. Interstitial cells of Cajal (ICCs) are pacemaker cells in the gastrointestinal (GI) tract. The present study investigated the effects of grape seed powder (GSP) on ICC properties and GI motility. GSP depolarized the pacemaker potentials of ICCs in a dose‑dependent manner. Y25130 or SB269970 slightly inhibited GSP‑induced effects. However, Y25130 and SB269970 together completely blocked GSP-induced effects. In the presence of inhibitors of protein kinase C, protein kinase A, or mitogen-activated protein kinase, GSP‑induced ICC depolarization was inhibited. GSP increased the intestinal transit rate in normal mice and in mice with acetic acid-induced GI motility disorder. In addition, the levels of motilin and substance P were elevated after GSP dosing. These results demonstrate that GSP can regulate GI motility, and therefore, it is a potential therapeutic agent for treating GI motility disorders.     

Retinal Layers Measurements following Silicone Oil Tamponade for Retinal Detachment Surgery

This study aimed to investigate the influence of silicone oil on the retinal nerve fiber layer (RNFL) thickness in patients with primary rhegmatogenous retinal detachment who underwent vitreoretinal surgery. The study included 47 patients (eyes), who underwent a pars plana vitrectomy with the silicone oil tamponade. The control group included unoperated eye of all participants. Spectral-domain optical coherence tomography (SD-OCT) was used for the measurements of peripapilar and macular RNFL thickness. The average peripapillary RNFL thickness was significantly higher in the silicone oil filled eyes during endotamponade and after its removal. The eyes with elevated IOP had less thickening of the RNFL in comparison to the eyes with normal IOP. Central macular thickness and macular volume were decreased in the silicone oil filled eyes in comparison to the control eyes. In conclusion, silicone oil caused peripapilar RNFL thickening in the vitrectomized eyes during endotamponade and after silicone oil removal.

骨髓增生异常综合征及慢性原因不明性粒细胞减少症患者骨髓CFU—GM和CFU—F的初步观察

利用人类骨髓粒一单核系祖细胞集落(CFU—GM)和成纤维细胞集落(CFU—F)体外检测技术,比较观察32例骨髓增生异常综合征(MDS)和11例慢性原因不明性粒细胞减少症(CIN)患者的造血改变。结果表明,MDS 和 CIN 的造血状态存在显著区别,69%的 MDS 患者 CFU—GM集落显著受抑,集簇、簇/落比值明显升高;其 CFU—F 集落亦存在明显缺陷。而 CIN 患者的上述指标均类似于正常。这提示体外集落检测技术有助于 MDS 和 CIN 的鉴别。此外,CFU—GM 系列培养对 MDS 患者具有一定预后价直。     

The role of interferon-gamma release assay in tuberculosis control

Tuberculosis is still one of the major global public health threats. Countries with low incidence must focus on exhausting the reservoir of future cases by preventing reactivation. Therefore, it is important to identify and effectively treat those individuals who have latent tuberculosis infection and who may develop active disease. The tuberculin skin test has been the standard for detection of immune response against M. tuberculosis since the beginning of the 20th century. The new millennium has brought advancement in the diagnosis of latent tuberculosis infection. The name of the new blood test is interferon-gamma release assay (IGRA). Croatia is a middle-incidence country with a long decreasing trend and developed tuberculosis control. To reach low incidence and finally eliminate tuberculosis, its tuberculosis programme needs a more aggressive approach that would include intensive contact investigation and treatment of persons with latent tuberculosis infection. This article discusses the current uses of IGRA and its role in tuberculosis control.
