The uncovered tracts and the liver wound surface were managed by some of the methods combined such as high frequency electrocoagulation, titanium clamp, suture, hemostatic gauze oppression, argon-beam coagulation, protein glue adherence, and Endo-GIA switcher. The total operative outcome, operating time, blood loss, postoperative complications and postoperative hospital stay were summarized in order to assess feasibility and safety of the clinical laparoscopic liver resection.Results: 1. Laparoscopic liver resection with clamp dissection method needs only the ordinary laparoscopic equipment. It has a low cost but causes a little more bleeding. 2. Laparoscopic liver resection operated by microwave tissue coagulation method had very little bleeding when dissecting hepatic parenchyma. The operative field is clear and the cost is low. It is a safe, convenient and effective method. 3. Ultrasound dissector is a relatively ideal appliance for laparoscopic liver resection at present because ofless bleeding during operation. But the speed is slow thus prolongs the operation time. Its separating intensity is not strong enough, and it can only be applied to patients without hepatic cirrhosis. 4. Ligsure has clamp dissection and electrocoagulation functions. It can carbonize hepatic tissue including the tracts whose diameters are less than 7mm. It has some advantage in dissecting. However, it has the shortcomings of the clamp dissector during coagulating. 5. Hand-assisted laparoscopic liver resection can make use of the flexibility and feeling of the operators left hand.
结果:1、钳夹分离切肝法不需特殊仪器设备,只要具备常规的腹腔镜器械即可实施,成本低,肝断面较易渗血;2、微波固化切肝法肝实质出血很少,视野清晰,成本低,操作简单,是一种安全、简便、有效的方法;3、超声刀是目前较为理想的切肝器械,术中出血少,但是,切割速度慢,手术时间长,而且,切割强度有限,适用于无肝硬化的肝切除;4、Ligsure具有挤压粉碎及高频电凝止血两大功能,可使包括7~以下管道的肝组织碳化、形成焦痴,具有一定的优势,但是,也存在分离钳电凝止血的缺点;5、手辅助腹腔镜肝切除可以利用术者左手的灵活性及手感,便于术中显露、分离、控制出血等,可随意协助右手及助手的主要操作,缩短了手术时间,大大提高了腹腔镜肝切除的安全性,李朝龙等的改良方法,同样达到了手辅助目的,又节省了费用;6、小切口腹腔镜辅助切肝法可以使用剖腹肝切除常规器械及剖腹肝切除技术,操作简单、可靠,适用于肝左外叶切除及右肝第V段切除;7、Endo一GIA切肝法在离断肝组织的同时闭合管道结构,多用于肝左静脉、门静脉分支、管径较大胆管的切割,缺点是不能用于较厚肝组织的切割,而且价格昂贵;8、临床巧例腹腔镜肝切除均获得成功,手术时间最短1.5h,最长sh,平均125 min,多数在100 min左右,手术出血量最少50 ml,最多500 ml,平均1 78 ml,除2例合并严重肝硬化的原发性肝癌患者术后出现少量腹水,1例术后发生胆漏外,其余无并发症,发生胆漏的1例患者术后住院40d,多数在术后一周左右出院,术后住院时间5一40d,平均gd。

The time and frequency of the polecat searching different preys and burrows were nearly the same. The polecat attacked virtually all prey offered and thus exhibited opportunistic foraging behaviour. However, it did not captured all prey with equal sequence. It first captured the zokor, then the pika and last for the root vole. In addition to using the typical musteline killing method of biting the nape of the neck, the polecat evolved a variety of killing methods suited to a range of prey types depending on the activity, size and anti-predation ability of prey. The zokor was bitten on the head, whereas the pika was killed by bites to the head or throat and the root vole was killed by bites to the head or chest. The time polecats pursued the root vole was the longest, followed by that used in pursuing the pika and the zokor.
实验结果表明:艾虎对三种猎物的搜寻时间和搜寻频次基本一致,在搜寻猎物的过程中并非已知洞道系统中所存在的食物信息,是一种机会主义的捕食者;艾虎除了具有典型鼬科动物捕杀猎物的方法外,能够根据猎物的大小、活动性和反捕食能力采用不同的捕杀方法,在捕杀猎物的过程中首先捕杀高原鼢鼠,其致死部位全部为头部,其次捕杀高原鼠兔,其致死部位除了头部外,明显增加了颈部的比例,最后捕杀根田鼠,其致死部位主要是头部和胸部;艾虎在捕杀猎物的过程中,追击根田鼠的时间最多,追击鼢鼠的时间最少,而用于捕杀根田鼠的时间最少,用于捕杀鼢鼠的时间最多,艾虎捕杀高原鼠兔后单位时间内获得的能量值最大,其次为捕杀高原鼢鼠,而捕杀根田鼠后单位时间内活动的能量值最小。
