摘要 目的:探讨质软胰腺胰十二指肠切除术(PD)中应用肝圆镰状韧带一体化包裹加强技术的临床价值。方法:回顾性分析哈尔滨医科大学附属肿瘤医院2016年1月至2021年12月实施开腹PD或保留幽门的胰十二指肠切除术(PPPD)质软胰腺病人的临床资料。根据是否应用肝圆镰状韧带一体化包裹加强技术分为无包裹加强组(2016.1-2018.12,246例)及包裹加强组(2019.1-2021.12,244例),比较两组病人基本临床特征、术中资料、术后资料、胰腺术后出血(PPH)病人治疗措施及转归。结果:术前基本临床资料中,两组病人在年龄、性别、术前高血压及糖尿病史、美国麻醉医师协会(ASA评分)、术前丙氨酸氨基转移酶、术前总胆红素、术前血清白蛋白、术前胆道引流、肿瘤位置及性质方面差异无统计学意义(P>0.05)。术中资料中,两组病人在手术时间、术中出血量、术中输血量、切除类型、PV 或SMV切除重建、主胰管直径方面差异无统计学意义(P>0.05)。术后资料中,两组病人在术后总体并发症、临床相关胰瘘(CR-POPF)及腹腔感染发生率、腹腔穿刺引流率、晚期腔外PPH及C级晚期腔外PPH发生率、PPH相关再手术率、总体再手术率、术后住院时间方面差异有统计学意义(P<0.05);两组病人在术后胆瘘、延迟性胃排空障碍、早期PPH、晚期腔内PPH、A级及B级晚期腔外PPH、围手术期死亡率方面差异无统计学意义(P>0.05)。PPH病人治疗措施及转归资料中,两组PPH病人侵袭性治疗率差异有统计学意义(P<0.05);两组PPH病人在不同侵袭性治疗措施及PPH病死率方面差异无统计学意义(P>0.05)。结论:肝圆镰状韧带一体化包裹加强技术能够降低质软胰腺PD术后总体并发症发生率、CR-POPF及晚期腔外PPH、C级晚期腔外PPH的发生率,同时降低病人腹腔感染发生率、腹腔穿刺置管引流率及再手术率,并缩短术后住院时间。 相似文献

A field experiment was carried out to determine the effects of the inoculation of onion (Allium cepa L.) with Glomus sp. Zac-19 on the development of onion white rot (Sclerotium cepivorum Berk.) and on onion production. Mycorrhization delayed onion white rot epidemics by 2 weeks and provided a significant protection
against the disease for 11 weeks after onion transplanting, as compared with nonmycorrhizal controls. Mycorrhizal plants showed
an increase of 22% in yield, regardless of the presence of the white rot pathogen.

Whitening of Gracilaria chilensis, accompanied by tissue softening and thallus fragmentation, was found to be associated with the presence of an endophytic
amoeba. Although the symptoms developed originally in green mutant thalli, subsequent infections in the laboratory also affected
normal, wild-type G. chilensis. Ultrastructural evidence indicates that the amoebae perforate the host cell walls of both cortical and medullary cells and
digest their protoplasm. Feeding by the amoeba appears to involve both phagocytosis and enzymatic digestion of the host tissue.
Destruction of the host tissue resulted in large cavities first, followed by thallus fragmentation. No other organism was
found during the early stages of thallus invasion by the amoeba, although bacteria may appear once the amoeba reaches the
inner tissues of the host. 相似文献

Summary The present review includes information on distribution, symptoms, inoculation techniques, disease rating, sources of resistance, genetics of resistance, breeding approaches for resistance, and the present status of resistance breeding with respect to Sclerophthora and Peronosclerospora downy mildews and Erwinia, Cephalosporium and Fusarium stalk rots. Some suggestions highlighting research gaps pertinent to future breeding strategies are mentioned.Publication No. 2993, Experiment Station, GB Pant University of Agriculture and Technology, Pantnagar, India 相似文献

Two populations of Meloidogyne arenaria (race 2, incompatible on peanut) enhanced development of Cylindrocladium black rot (CBR) on CBR-resistant peanut cv. NC 3033 in greenhouse factorial experiments. Nematode populations 256 and 486 (0, 10³, 10⁴ eggs per 15-cm pot) were tested in all combinations with Cylindrocladium crotalariae (0, 0.5, 5, 50 microsclerotia per cm³ of soil). Root-rot index increased in the presence of either population. Positions but not slope values of inoculum density-disease curves were changed by both populations, indicating increased efficiency of microsclerotia when peanuts were grown in the presence of these nematodes. Although little or no reproduction occurred with either nematode population on NC 3033, larvae of 256 and 486 penetrated roots. Meloidogyne arenaria 486 did not induce root galls and was not snccessful in establishing feeding sites. Meloidogyne arenaria 256 produced a few very small eliptical galls and had a range of success in establishing a feeding site, varying from no giant cell development to large giant cell with production of a few eggs. 相似文献

Optoelectronic motion capture systems are widely employed to measure the movement of human joints. However, there can be a significant discrepancy between the data obtained by a motion capture system (MCS) and the actual movement of underlying bony structures, which is attributed to soft tissue artefact. In this paper, a computer-aided tracking and motion analysis with ultrasound (CAT & MAUS) system with an augmented globally optimal registration algorithm is presented to dynamically track the underlying bony structure during movement. The augmented registration part of CAT & MAUS was validated with a high system accuracy of 80%. The Euclidean distance between the marker-based bony landmark and the bony landmark tracked by CAT & MAUS was calculated to quantify the measurement error of an MCS caused by soft tissue artefact during movement. The average Euclidean distance between the target bony landmark measured by each of the CAT & MAUS system and the MCS alone varied from 8.32 mm to 16.87 mm in gait. This indicates the discrepancy between the MCS measured bony landmark and the actual underlying bony landmark. Moreover, Procrustes analysis was applied to demonstrate that CAT & MAUS reduces the deformation of the body segment shape modeled by markers during motion. The augmented CAT & MAUS system shows its potential to dynamically detect and locate actual underlying bony landmarks, which reduces the MCS measurement error caused by soft tissue artefact during movement. 相似文献
