世界核心医学期刊文摘（胃肠病学分册） 2005年第1期1卷 34-35页

Background Elastic band ligation by means of a rigid proctoscope is the treatment of choice for patients with symptoms caused by internal hemorrhoids of grade 2 to 3. In contrast to the flexible videoendoscope, the rigid proctoscope has limited maneuverability, has a narrower field of view, and does not allow adequate documentation. therefore, a randomized trial was conducted to compare the safety and the efficacy of conventional elastic band ligation with videoendoscopic elastic band ligation. Methods A total of 100 consecutive patients(mean age 47 12 years) with chronically bleeding grade 2 or 3 internal hemorrhoids were randomized to elastic band ligation or videoendoscopic elastic band ligation. For videoendoscopic elastic band ligation, a reusable multiband ligator was attached to the end of a therapeutic upper videoendoscope. From one to 3 bands were placed per session in both groups. Re-treatment was performed every 2 to 3 weeks in both groups until cessation of bleeding and eradication of the hemorrhoids (at least grade 2) were achieved. thereafter, the patients were followed to assess complications and efficacy. Recurrent bleeding was considered a treatment failure. Results to achieve the desired therapeutic aims, a significantly lower number of treatment sessions was required in the videoendoscopic elastic band ligation group (1.8 0.8 vs. 2.4 0.9; p the total number of bands applied was significantly less (2.8 1.1 vs. 3.7 1.4; pted after ligation by 25% of patients in the elastic band ligation group compared with 27% of those who had videoendoscopic elastic band ligation. However, analgesic medications were required in only 7% after elastic band ligation and 9% after videoendoscopic elastic band ligation (NS). Postligation bleeding that had to be treated endoscopically occurred in 3.5% of the patients of the elastic band ligation group and 3.2% of those in the videoendoscopic elastic band ligation group(NS).

the thermal conductivities of different typical species filling materials for sliding gate systems for steel ladles were measured using a hot wire technique, and the relationships between thermal conductivity and temperature were regressed. the factors affecting thermal conductivity were analyzed by using variance analysis for a perpendicular experiment. the effects of thermal conductivity on sliding gate free tapping were studied, and it was revealed that decreasing the thermal conductivity of the filling materials is beneficial in enhancing the rate of free tapping for sliding gates.

前言运动员生理特征的测定,被称为运动轮廓描述,最近已变得非常普及,以至到了近来的讨论会几乎都是测量方面的内容。实验室里身体机能测定,在给一定的活动或运动时,被认为是敏感和有效的,它可以指出运动损伤的预兆。尽管所有冰球运动员的持拍手有一定的优势,但是否会造成腹股沟、腘旁腱肌的力量和柔韧性以及肩带肌力量的不对称,还不能肯定当试图使受伤运动员恢复时,这些因素可能十分主要。正如斯莫莱卡论述的那样,在损伤之后,了解身体两侧的差异,以及正常的力量性和柔韧性对运动损伤的恢复是十分必要的。因为恢复到正常的竞赛状态,完全取决于正常功能的恢复,包括肌肉的力量和柔韧性。在许多种运动中,包括冰球运动员在内,对不同技能水平运动员特征的文献已有报导。然而。

two-stage double peaks ageing and its effect on stress corrosion cracking susceptibility of Al-Zn-Mg alloy

journal of Materials Science & technology 2018年第7期34卷 1250-1257页

Different artificial two-stage ageing behaviors and their effect on stress corrosion cracking （SCC） susceptibility of AI-Zn-Mg alloy have been investigated. the experimental results show that two hardness peaks present on the second-stage ageing-hardening curve when the first-stage ageing is dealt with comparatively lower temperature than the conventional one. the first peak is caused by dispersive and evenly distributed G.P. zones, while η ′phases and coarsened G.P. zones contribute to the second peak. tensile strength of experimental alloy raises 9.6% （33.2 MPa） and SCC susceptibility decreases 38.9% by applying the second peak ageing regime instead of conventional t73. AI-Zn-Mg alloy obtains high strength and SCC resistance due to its finely dispersive matrix precipitates （MPts）, coarsened and discontinuous grain boundary precipitates （GBPs）, as well as the narrow precipitate free zone （PFZ） in the second peak ageing condition. 2017 Published by Elsevier Ltd on behalf of the editorial office of journal of Materials Science ＆ technology.

血清学方法在研究黄化病毒组方面一直是特别有用的,因为这类病毒不能用机械方法传播到植物上,病毒在病株中的含量又很低,在用蚜虫作媒介进行病毒传播研究中,会遇到各种各样的困难.目前,有用的技术已从一种侵染性中和法延伸到酶联免疫吸附测定(ELISA).尽管这些方法有许多优点,但是由于在制备动物抗血清中,要准备足够数量的纯化病毒有某些困难;同时,由于黄化病毒之间的血清学特异性,以及不同动物,甚至同一动物不同个体的抗血清之间,常常发生变异,因此需要多种多样的抗血清,而目前这种抗血清的供应仍很有限;所以这些方法在应用上还是受限制的.

Objective: to correlate repetitive nerve stimulation (RNS)- decrement in different muscles with the predominant clinical presentation in myasthenia gravis (MG), and to study single fibre EMG (SFEMG) sensitivity in ocular MG. Methods: Sixty- nine, untreated, consecutive patients suspected for MG were observed prospectively for a minimum of 6 months. those who improved on medical treatment were diagnosed as MG. the others, in whom the neurophysiological studies were normal and that did not improve on medical treatment served as a control group, from which normative data for RNS and SFEMG was obtained. the MG patients were further classified in 3 subgroups according to the predominant clinical presentation: group I (ocular); group b (bulbar); and group a (axial). We performed RNS in nasalis, trapezius, anconeus, and abductor digiti minimi. All patients with ocular MG underwent jitter determination of the orbicularis oculi muscle. Results: thirty- seven patients were diagnosed as MG (group I, 15; group b, 13; group a, 9). In group I, RNS was abnormal in 33% of the patients. RNS studies disclosed at least one abnormal muscle response in every patient in groups a and b. trapezius was significantly more sensitive in group a, and anconeus and nasalis in group b (P jitter was abnormal in all patients in group I, and the most sensitive parameter was an increased number of unstable pairs, 100% . Conclusions: Based on these observations, we recommend that a shoulder muscle, as the trapezius, should be studied first in the limb- axial presentation of MG, and the anconeus- nasalis muscles in predominant bulbar MG. In ocular MG, RNS is not sensitive and jitter should be performed in facial muscles. Significance: this paper shows the unequal sensitivity of several muscles to RNS in different forms of MG.
