Comparison of uncut Roux-en-Y anastomosis and traditional Roux-en-Y anastomosis in the totally laparoscopic distal gastrectomy for gastric cancer: An analysis of multiple centers' data

目的对比非离断式(Uncut)Roux-en-Y吻合和传统Roux-en-Y吻合应用于全腹腔镜远端胃癌根治术后消化道重建的安全性和短期疗效。方法回顾性分析国内10家单位共60例远端胃癌根治术后全腹腔镜消化道重建的胃癌病人临床资料,根据消化道重建方式不同分为Uncut Roux-en-Y组(Uncut组)34例,传统Roux-enY组(传统组)26例。结果 Uncut Roux-en-Y吻合在消化道重建时间方面用时更短[(51.5±13.3)min vs.(80.4±16.2)min,P=0.000],出血量更少[(60.0±35.6)m L vs.(132.9±65.1)m L,P=0.000],且在进食半流饮食时间方面具有优势[(4.6±1.5)d vs.(7.2±2.3)d,P=0.000]。两组病人在留置胃管时间、术后排气时间、进食流质时间和术后住院时间方面差异无统计学意义。两组病人均无围手术期死亡病例,并发症发生率差异无统计学意义(8.8%vs.7.7%,P=0.875)结论 Uncut Roux-en-Y吻合和传统Roux-en-Y吻合应用于全腹腔镜下消化道重建安全可行,Uncut Roux-en-Y吻合在重建时间和控制出血量方面具有优势。Objective To compare the security and short-term effect of the digestive tract reconstruction during the totally laparoscopic distal gastrectomy for gastric cancer between the Uncut Roux-en-Y anastomosis and the traditional Roux- en- Y anastomosis. Methods The clinical data of 60 gastric cancer patients with digestive reconstruction underwent totally laparoscopic distal gastrectomy between December 2012 and June 2015 in 10 domestic hospital were analyzed retrospectively. According to the difference of digestive reconstruction,it can be divided into the Uncut Rouxen-Y anastomosis group with 34 patients and the traditional Roux-en-Y anastomosis group with 26 patients. Results In uncut Roux-en-Y anastomosis group,the operative time in digestive reconstruction was shorter[(51.5±13.3)min vs.(80.4±16.2)min,P=0.000]; the intraoperative blood loss was less[(60.0±35.6)m L vs.(132.9±65.1)m L,P=0.000];semi-liquid diet time was earlier[(4.6±1.5)d vs.(7.2±2.3)d,P=0.000]. However,there was no difference between the two groups on nasogastric tubegastrointestinaltwo groups on nasogastric tube,gastrointestinal transit,fluid diet and the duration of postoperative hospital stay. Both groups had no death case during the perioperative period and there was no significant statistical difference in the postoperative complication rates(8.8% vs. 7.7%,P=0.875).Conclusion The Uncut Roux- en- Y anastomosis and the traditional Roux-en-Y anastomosis are both safe and feasible for the digestive reconstruction under the totally laparoscopic distal gastrectomy for gastric cancer. Besides,the Uncut Roux- en- Yanastomosis has other advantages such as less reconstruction time and less bleeding.广东省科技计划项目(No.2014A020212591

Academic and clinical experience of professor WANG Yan-hui in treatment for cancer with heavy prescription

文章总结了厦门大学医学院王彦晖教授治疗癌症的临床经验,突出了其善用重剂治疗癌症的特色。王彦晖教授认为,癌症本质上是实证,痰浊和瘀血贯穿于癌症病程的全过程,在癌症的病理病机中,痰瘀是相对不变的,而气滞、寒热、肺虚、脾虚、肾虚等病理病机则是可变的;癌症的治疗,王教授善用重剂,非常重视化痰散结和活血化瘀的治法,并注意处理好祛邪与扶正的关系、调理好寒热和气机升降出入的状态;王教授认为,应该重视中医药在癌症预防方面的独特作用。最后,文章以两个典型病案展示了王彦晖教授治疗癌症的学术特色。The academic and clinical experience of WANG Yan-hui, the professor of medical college of Xiamen University, treated the cancer with heavy prescription was introduced in this paper.Professor WANG Yan-hui thought that excess syndrome was the essential syndrome of cancer and the pathogenic effect of phlegm and blood stasis was throughout its whole process.In the pathological mechanism of cancer, phlegm and blood stasis were relatively invariable, on the contrary the others such as qi stagnation, coldness and heat, lung deficiency, spleen deficiency, kidney deficiency and so on were variable.In the treatment of cancer, heavy prescription was used by professor WANG, who paid attention to reduce phlegm and resolve masses, promote blood circulation to remove blood stasis, the balance of eliminating evil and strengthening the body resistance, the regulation of coldness and heat and the ascent, descent, going out and in of qi.Professor WANG thought that the distinctive effect of Chinese medicine in the treatment of cancer should be valued.Finally, two typical cases were selected for showing the academic characteristic of professor WANG in the treatment of cancer.厦门市重大科技计划项目(No.3502Z20100006)~

Si-Cu合金化渣剂精炼去除冶金级硅中金属杂质

采用Si-Cu合金精炼与CaO-SiO2-CaCl2造渣精炼相结合的方法对冶金级硅进行精炼,通过多种分析方法考察了合金造渣过程、渣剂添加剂和合金成分对金属杂质铁（Fe）、铝（Al）和钙（Ca）去除效果的影响。结果表明,提高Si-Cu合金中的Cu含量可以有效增加Cu3Si相在Si中的含量,合金造渣过程会产生多而弥散的合金相,造渣后的金属杂质Fe、Ca聚集在Si-Cu合金的Cu3Si相中。在渣剂中添加CaCl2助溶剂可有效提高金属杂质Fe、Al和Ca的去除率。此外,随着Si-Cu合金中Cu含量的增加,Cu在合金中的析出现象明显,Fe的去除率上升,Al的去除率不变,Ca的去除率下降。当Si-30%Cu合金与45%CaO-45%SiO2-10%CaCl2渣剂进行精炼后,Fe的去除率为68%,Al的去除率为94%,Ca的去除率为86%

人工气候箱在“六淫”研究中的应用

“六淫“的发生与气候密切相关,人工气候箱可以模拟出自然界可能出现的各种气候类型,为“六淫“实验研究的最重要手段之一,已在风、寒、湿、燥邪等研究中取得一定成果。然而由于气候对人体的影响规律尚不明确,所以研究中还存在同种邪气气候箱条件设置各异、动物在气候箱放置时间各异等问题,也是“六淫“研究今后要深入探讨的问题。认为随着人工气候箱的发展,可以模拟出更精确、复杂的气候环境,可望在“六淫“和其他气候相关科研中发挥更大作用。国家自然科学基金资助项目(81302876); 福建省自然科学基金资助项目(2013J05123

A Study on the Cytotoxic and Genotoxic Effects of Rare Earth Multi-element Compound Fertilizer (RE-MECF) on Zea mays L.

为了研究常乐稀土多元复合肥对主要农作物--玉米(Zea mays L.)是否产生细胞毒性和遗传毒性效应,采用不同梯度质量浓度的稀土复合肥溶液对玉米进行处理,观察其根尖生长状况,统计分析细胞死亡率、微核率、有丝分裂指数以及对细胞DNA的损伤情况.结果表明,质量浓度为10mg·L-1以下时,常乐稀土复合肥能够促进玉米根尖的生长,100mg·L-1以上时抑制根尖生长;随着试验浓度的递增,细胞死亡率、微核率、DNA损伤率逐渐上升并具有正相关性,表现出明显的剂量-效应关系,而有丝分裂指数却随着浓度的增加逐渐下降.以上结果表明,常乐稀土复合肥对玉米确有一定的细胞毒性和遗传毒性效应,其细胞毒性阈值和遗传毒性阈值皆为100mg·L-1.The root tips were treated with different concentrations of Rare Earth Multi-element Compound Fertilizer(RE-MECF)in order to evaluate the effect on maize in terms of the growth of root-tip, the mortality, the frequency of micronucleus(FMN),mitosis index(MI)and DNA damage. The results indicated that the dosage below 10mg·L-1 (expressed by concentration of RE-MECF) could accelerate the growth of root tips of Zea mays L., but the groups which were treated by the dosages above 100mg·L-1 were repressed. The mortality, frequency of micronucleus(FMN)and DNA damage increased while mitosis index(MI)decreased with increasing concentrations, from which, the dosage-effect relationship was clearly demonstrated. These results suggested that the RE-MECF had certain cytotoxic and genotoxic effect, and that the cytotoxic and genotoxic threshold dosages were both 100mg·L-1.国家自然科学基金项目(No.30470421);; 江苏省高等学校自然科学基金项目(No.D180215
