非溃疡性消化不良的幽门螺杆菌研究

本研究旨在观察幽门螺杆菌（ＨＰ）在非溃疡性消化不良（ＮＵＤ）发病中的作用。结果显示，ＮＵＤ患者ＨＰ阳性率为８３．６％，ＨＰ感染率显著高于健康人（Ｐ＜０．０１）。提示幽门螺杆菌在非溃疡性消化不良发病机制中可能有重要意义。     

THE EFFECT OF ACUPUNCTURE ON PREVENTION AND TREATMENT OF ISCHEMIC ARRHYTHMIA AND THE RELATION BETWEEN EFFECT OF ACUPUNCTURE AND CHOLINERGIC MUSCARINE-LIKE RECEPTORS

For investigating the effect of acupuncture on ischemic arrhythmia and its mech-anism, adult albino rats with ligated anterior descending branch of coronary artery as experimentalmodel were treated with or without acupuncture, and others with imitative operation but without bothcoronary artery ligation and acupuncture treatment were used as control. It was found in acupuncturegroup that the fibrillation-liability of ischemic myocardium was efficiently decreased, the affinity ofAch-M receptors on membranes of ischemic myocardium was markedly increased, and the tolerance ofischemic myocardium to atropine was elevated in the experiment of atropine inducing fibrillation.These results indicate that acupuncture may play a therapeutic role on ischemic arrhythmia throughactivating the activity of muscarine-like receptors of cholinergic nervous system.     

产后4个月内未能坚持纯母乳喂养的因素分析

通过239对母婴产后4个月的跟踪随访发现,在130位母亲未能自始至终坚持纯母乳喂养的因素中,最主要的是自觉奶量不够或者因孩子哭吵、怕孩子吃不饱而添加辅助液体或食品,其次是按旧习惯从出生后3个月起添加米糊类食品,以及医务人员的错误指导和母亲上班等。纯母乳喂养的关键在于必须排除一切干扰,增强母亲的信心。因此,尽快转变旧观念,大力宣传出生后4～6个月纯母乳喂养的重要性,普及泌乳生理知识和哺乳中常见问题的处理方法,加强随访工作,是提高4个月内纯母乳喂养率的重要措施。     

杂多阴离子对SiO_2细胞毒性的拮抗作用

本文采用离体细胞培养法,以细胞存活率、乳酸脱氢酶活性和酸性磷酸酶活性为指标,研究了几种α-Keggin结构的杂多阴离子对石英粉尘细胞毒性的影响。结果表明,与对照组比较,所用杂多阴离子无细胞毒性(P>0.05),石英尘经杂多阴离子作用后,细胞毒性显著降低,与石英尘组比较,上述三项指标差异均有显著意义(P<0.01),由此表明杂多阴离子对石英的细胞毒性有明显的拮抗作用。     

Fluorescence in situ hybridization analysis of chromosome 12p in paraffin-embedded tissue is useful for establishing germ cell origin of metastatic tumors.

The over-representation of chromosome 12p sequences is crucial for the development of invasive testicular germ cell tumors. Testicular cancer patients may have metastatic tumors of diverse histologic types, including adenocarcinoma, undifferentiated carcinoma, sarcoma, or other malignancies that lack features of germ cell tumors. We sought to investigate the possible germ cell origin of such tumors using interphase fluorescence in situ hybridization. In all, 10 metastatic malignant somatic-type tumors from patients with histories of testicular cancer, as well as one malignant somatic-type tumor from a patient with primary mediastinal germ cell tumor were studied and included: adenocarcinoma (five cases), poorly differentiated carcinoma (one), sarcoma (four), and neuroendocrine carcinoma (one). The tumors were analyzed using fluorescence in situ hybridization using 12p spectrum green and 12 centromeric spectrum orange probes in paraffin sections. The patients ranged in age from 27 to 55 years (mean, 43). Colon and lung cancers from patients without germ cell tumors were used as controls. Adequate signals were observed in all tumors. Gain of chromosome 12p was seen in six tumors. None of the control tumors showed 12p amplification. Fluorescence in situ hybridization for 12p amplification in routinely processed surgical specimens is a useful adjuvant diagnostic tool in confirming the germ cell origin of metastatic tumors having the histologic appearance of somatic-type neoplasms.     

Evaluation of peripheral blood involvement of mantle cell lymphoma by fluorescence in situ hybridization in comparison with immunophenotypic and morphologic findings.

Mantle cell lymphoma is non-Hodgkin's B-cell lymphoma characterized by the t(11;14)(q13;q32) translocation. Peripheral blood involvement of mantle cell lymphoma is usually associated with a poor prognosis and therefore, its identification is clinically important. In this study, we performed cyclin D1/IgH-probe fusion fluorescence in situ hybridization analysis on 223 peripheral blood samples: 185 from 125 mantle cell lymphoma patients, and 38 normal controls. The cutoff values for the test were established using normal controls. Flow cytometry on peripheral blood and corresponding bone marrow samples was used to evaluate this test. In all, 26% of the 185 peripheral blood samples and 27% of the 161 corresponding bone marrow samples were flow cytometry positive for mantle cell lymphoma. The mean numbers of single and- double-fusion signals and the mean number of CD5/CD19-positive cells, absolute blood lymphocyte count, and white blood cell count were significantly higher in peripheral blood and corresponding bone marrow samples with mantle cell lymphoma-positive flow cytometry. Double-fusion signals were more specific than single-fusion ones. Fluorescence in situ hybridization was far more likely to be positive for mantle cell lymphoma when the peripheral blood and the corresponding bone marrow samples had positive flow cytometry results or morphology (P<0.01). Our study indicates that cyclin D1/IgH-fusion fluorescence in situ hybridization analysis could be used to determine the presence and character of circulating mantle cell lymphoma cells in peripheral blood, thus enhancing our ability to evaluate leukemic mantle cell lymphoma and minimum residual disease.     

肝癌切除术后辅助肝动脉栓塞化疗的价值

关于原发性肝癌的现有各种治疗手段如外科治疗、微创治疗（肝动脉栓塞化疗、微波射频消融治疗、无水酒精瘤内注射）、放射治疗、化学治疗、免疫治疗和中医中药治疗，都有一定的疗效，但至今仍以手术切除为最有效的治疗方法。近20年来，通过亚临床期肝癌的发现、早期切除、肝癌术后复发的再切除和不能切除肝癌的缩小后再切除、多学科的有序的综合治疗等方法，在一定程度上提高了术后生存率。由于肝癌有早期就容易出现肝内转移的特性，大部分肝癌在手术时已存在有肝内转移灶，所以术后余肝残留肿瘤的机会很大，术后复发率高。
