日本临床肿瘤组最近进行了一项大规模临床试验,结果揭示了可切除的胃癌手术治疗的关键策略。研究发现:与D2淋巴结清扫术相比,D3淋巴结清扫术不能提高生存率,且不推荐用于可切除的胃癌。此外,对于侵犯食管≤3 cm的食管–胃交界处或胃贲门腺癌的治疗,建议采用经食管裂孔入路,而非左胸腹入路。过去建议将胃切除伴脾切除术和网膜囊切除术作为D2淋巴结清扫术的一部分。然而,最近的临床试验结果显示,对于近端胃癌,伴D2淋巴结清扫的全胃切除术应避免脾切除术;对于可切除的胃癌,伴D2淋巴结清扫的胃切除术应避免网膜囊切除。脾切除术和网膜囊切除术均不能提高生存率,反而增加手术并发症。这些试验结果表明,上述侵入性和激进性手术未能使患者得到生存获益,胃癌手术可能将向"从侵入性到低侵入性"和"从激进到较保守"的趋势发展。

Journal of Hydrodynamics 2007年第3期19卷 356-364页

作者： KUBOTA takashi College of Electric Power South China University of Technology Guangzhou 510640 China

Different from the reaction turbines, the hydraulic performance of Pelton turbine is dynamic due to the unsteady flow in the rotating buckets in time and space. The dynamic energy efficiency of bucket ηεB and power efficiency of bucket ηPB within a short period can be predicted from the dynamic flow pattern of the free-surface sheet flow in the rotating bucket, whereas the dynamic discharge efficiency of bucket ηQB is defined as the resident discharge in the bucket at the respective moment. Under the operation of higher unit speed non than the optimum one, the power efficiency of bucket is deteriorated by the jet interference with the rear surface of bucket △Prear at the first stage of the dynamic performance, as well as the loss power due to the spilt flow from the cutout of bucket at the later stage of performance. Based on the dynamic performance prediction presented, the future possibility of the quantitative investigation for the negative scale effect of Pelton turbines was discussed.
