密度和氮肥互作对夏直播棉花群体发育和产量的影响

针对长江流域棉区传统植棉模式生产成本高、种植效益低等问题,创建了以"晚播、增密、减氮、见花一次施肥、秸秆还田和阈值管理"为特点的夏直播棉花种植模式,该模式得到广泛应用。为揭示这一新模式提高氮肥利用率、稳定棉花产量的理论基础,2017—2018年采用大田试验探讨了密度和氮肥互作对棉花群体发育和产量的影响。以华棉3097为材料,裂区设计,2个密度(D1,6株·m.D2,8株·m.为主区,3个施氮量(N1、N2和N3分别为150、180和210 kg·hm.为副区,调查了棉花产量及其构成因素、干物质累积、氮素利用和冠层结构等。结果表明:D1时,N3籽棉产量最高(2 831.1 kg·hm.2),比N1和N2分别高14.8%和5.8%;D2时,N3产量(3 014.9 kg·hm.2)较N1增加9.2%,但与N2无差异。逐步回归分析表明,每平米增加1株或1个铃,棉花产量增加63.6或20.1 kg·hm.通径分析表明,棉花产量与库器官生物质量直接相关系数(p=0.70)最大,而源器官和流器官通过库器官对产量起间接作用。同时,棉花产量与生物质累积的最大值(K,R=0.92)、快速累积期平均累积速度(V,R=0.70)、生长期间最大累积速率(R,R=0.87)正相关。此外,D2N2氮素表观利用率(16.6 g·g)和库器官分配比例(73.8%)相对较高。相较于D1,D2提高了群体早期冠层光拦截和生育期最大光拦截率,高效光拦截(>70%)持续期延长了7.4%;D2降低了花铃期冠层白天平均气温、最高气温和相对湿度。综上,夏直播棉花增密减氮在实现群体生物质(尤其是库器官生物质)快速累积的同时,构建了光氮高效利用的群体结构和适宜的冠层环境,维持了产量的稳定。

早产儿和足月儿骨骼的定量超声评估

世界核心医学期刊文摘（儿科学分册） 2005年第12期1卷 12-12页

作者： m.Devitt H. Tom.inson C. White m.P. ahmed S.F. 贺莉 Bone and Endocrine Research Group Royal Hospital for Sick Children Yorkhill Glasgow G3 8SJ United KingdomDr.

There is a need to explore novel m.thods of assessing bone health in sick preterm.infants. This study of the speed of sound in the long bones of newborn term.and preterm.infants shows that, in this population, this technique is not site specific and has a high degree of interobserver and intraobserver precision. The speed of sound in newborn infants is prim.rily dependent on gestation rather than birth weight.

AIm. To investigate the prevalence of enteric parasite contam.nation on hands and the potential role naturally contam.nated hands m.y have in their transm.ssion. m.THODS: Prior to initiating the survey, the protocol was reviewed and approved by respective Institutional Review Boards of each survey site(Dhaka, Bangladesh and Kolkata, India). Both stool and corresponding hand wash sam.les collected, were analyzed for the presence of enteric parasitic ova/(oo)cysts em.loying conventional m.croscopy coupled with perm.nent staining techniques. Additionally m.lecular approachessuch as polym.rase chain reaction(PCR) of enteric parasites recovered from.both stool and corresponding hand wash sam.les, were also used to further confirm.their identity. RESULTS: A total of 972 stool sam.les were collected from.both sites surveyed(300 volunteers from.Kolkata, India and 672 from.Dhaka, Bangladesh). Parasitic analysis revealed, 113(38%) from.Kolkata, India and 267(40%) of stool sam.les from.Dhaka, Bangladesh were positive for parasitic ova/(oo)cysts. When the corresponding hand wash sam.les were analyzed, 43(14%) stool-positive volunteers in Kolkata, India and 47(7%) in Dhaka, Bangladesh were positive for enteric parasitic ova/(oo)cysts. Ascaris lum.ricoides(A. lum.ricoides) ova and Giardia lam.lia(G. lam.lia) cysts predom.nated in hands wash sam.les from.both sites surveyed(from.India, A. lum.ricoides ova, 53%; G. lam.lia cysts 31% and from.Bangladesh, A. lum.ricoides ova, 47%; G. lam.lia cysts 19%). Genotypic analysis of enteric parasitic ova/(oo)cysts obtained from.both stool and corresponding hand wash sam.les taken from.the sam. person were found to be identical. CONCLUSION: These results suggest a possible role of hands contam.nated with enteric parasites' ova/(oo)cysts in the transm.ssion of these parasites highlighting another role of hand hygiene/proper hand washing in reducing the disease burden in low socioeconom.c com.unities.

目的确定进行射频消融和全身化疗的结直肠癌肝转移病人的长期(10年)生存率。材料与方法研究获得单位伦理委员会批准。1997年—2006年间,99例病人共202个小结直肠癌肝转移灶[0.8～4.0cm.平均(2.2±1.1)cm.进行了超声导向下采用内部冷却电极的经皮射频消融治疗,同时进行全身化疗。所选病例包括不适合手术(n=80)和拒绝手术(n=19)的病人。射频消融后采用对比增强CT和(或)m.I检查进行3～10年的随访(随访3、5、7和10年的病例数分别为99、67、49和25)。评价局部有效率和长期生存率。对于每个结束点生成Kaplan-m.ier曲线,采用对数秩检验评价统计学的差异性。结果首次和再次治疗的成功率分别为93.1%(188/202)和100%(14/14)。11.9%(24/202)的转移灶出现局部进展,其中54.2%(13/24)进行再次治疗。再次治疗病人的生存率较没有再次治疗者明显增加(P<0.001)。在随访中,发现了125个新的肝转移灶,其中32.8%(41/125)接受了射频消融治疗。1、3、5、7和10年的总体生存率分别为98.0%、69.3%、47.8%、25.0%和18.0%(中位数为53.2个月)。主要并发症的发生率为1.3%(2/156),没有出现与治疗相关的死亡。撰写本文时32.3%(32/99)的病人还活着,67.7%(67/99)的病人已经死亡,平均随访时间为72个月。结论全身化疗联合射频消融治疗,能局部控制大部分的结直肠癌肝转移灶。此大样本病人的3～10年生存率,基本上与文献报道的大部分手术者的生存率相当。
