南阳市玉米穗腐病致病镰刀菌种群结构分析

镰刀菌是玉米穗腐病的主要病原菌.本研究对南阳市5县2009年夏玉米穗腐病致病镰刀菌的种群结构进行调查分析.从病样中按常规组织分离法进行病原菌分离,对分离物经单孢分离纯化后根据柯赫法则进行致病性检测,并根据形态特征和核糖体基因内转录间隔区（rDNA-ITS）序列对病原菌进行鉴定.从采集的80份穗腐病样品中分离获得105株镰刀菌,接种结果表明,所有菌株对玉米均有致病性.形态和分子鉴定结果表明,引起南阳市玉米穗腐病的镰刀菌至少有4种：层出镰刀菌Fusarium proliferatum、串珠赤霉菌Gibberella monoliformis、木贼镰刀菌F.equiseti及玉蜀黍赤霉菌G.zeae.南阳市玉米穗腐病致病镰刀菌以层出镰刀菌为优势种,串珠赤霉菌为次优势种.     

福建省不同居群长柄石杉石杉碱甲含量的研究

实地采集标本并用改进的HPLC法测定了福建省不同地区16个居群间长柄石杉的石杉碱甲(Hup A)含量。结果显示,石杉碱甲在长柄石杉福建省不同居群间均有分布,其中以梁野山和新罗区黄连盂两个居群含量较高,分别为0.047 7%和0.046 4%;从区域上看,龙岩地区含量最高,平均为0.041 6%,三明地区含量次之,平均为0.041 4%,宁德地区含量最低,平均为0.019 7%。结果表明,福建地区拥有良好的石杉碱甲植物资源。     

内镜黏膜下剥离术治疗早期食管癌及食管癌前病变

研究内镜黏膜下剥离术(ESD)治疗早期食管癌及食管癌前病变的治疗价值。对25例早期食管癌及食管癌前病变在确定病变范围及浸润深度后行黏膜下剥离术。先超声内镜判断浸润深度及利用Lugol液染色确定病灶范围,后采用术中标记、粘膜下注射、边缘粘膜切开、剥离及创面处理等方法。结果显示,病灶完整切除,术中无穿孔、出血;术后3、6、12月常规随访,均无复发。1例术后3个月出现食管狭窄,给予扩张后狭窄缓解。结果表明,对早期食管癌及食管癌前病变,内镜黏膜下剥离术是一种安全的内镜下治疗方法。     

发挥编辑大智慧 推动专题策划的实践和创新——以《山东医药》骨外科系列专题为例

Patients＇ quality of life after laparoscopic or open cholecystectomy

Objective: This study was aimed at evaluating and comparing the quality of life in patients who underwent laparo-scopic and open cholecystectomy for chronic cholecystolithiasis. Methods: The study included 25 patients with laparoscopic cholecystectomy (LC group) and 26 with open cholecystectomy (OC group). The quality of life was measured with the Gastrointestinal Quality of Life Index (GLQI) preoperatively, thereafter regularly at 2, 5, 10 and 16 weeks after the operation. Results: The mean preoperative overall GLQI scores were 112.5 and 110.3 in LC and OC group respectively (P>0.05). In the LC group, the mean overall GLQI score reduced slightly to 110.0 two weeks after the operation (P>0.05). The LC group showed significant improvement in overall score and in the aspects of symptomatology, emotional and physiological status from 5 to 16 weeks postoperatively. In the OC group, the GLQI score reduced to 102.0 two weeks after surgery (P<0.05). Significant reductions were shown in the aspects of symptomatology, physiological and social status. The GLQI scores returned to the preoperative level of 115.6 ten weeks after the operation (P>0.05). The patients experienced significant improvements of GLQI sixteen weeks after OC operation (P<0.01-0.05). Within the 10 postoperative weeks, the LC group had significantly higher GLQI scores than the OC group (P<0.05). Conclusions: LC can improve the quality of life postoperatively better and more rapidly than OC. The assessment of quality of life assessment is a valid method for measuring the effects of surgical treatment.

Video-assisted thoracic surgery―the past, present status and the future

VATS,THE PAST Historical perspective The application of thoracoscopy can be traced back to nearly one hundred years ago,when Dr.Jacobaeus(1910)first reported his experiences in the diagnosis and treatment of pleural effusions by tho-racoscope in1909.Most patients who needed to un-dergo thoracoscopy at that time suffered from pul-monary tuberculosis(TB)(“the era of enthusiasm”)(Cutler,1933),and was rarely performed after the development of chemotherapy for patients with TB after the195…
