3.The Chifengshan gold-polymetallic deposit is located in the Beishan polymetallic mineralization belt. There are 114 gold-polymetallic veins in the area, among them 19 are gold veins and auriferous veins, they occurred in the marble of Jixian System Pingdingshan Group which located in the north contact zone between biotite adamellite rock body and porphyritic granodiorite stock of Later Variscan, and controlled by the contact zone skarnization belt and EW, NE, NW and NNW strike fault.
赤峰山金 多金属矿位于北山多金属成矿带,区内共发现金 多金属矿脉114条,其中金和含金矿脉19条,均产于华力西晚期黑云二长花岗岩体和斑状花岗闪长岩株北接触带上的蓟县系平顶山群大理岩中,受接触带夕卡岩化带及近EW、NE、NW和NNW向断裂所控制。
4.Methods:30 lower limb veins with CVI and 40 normal limb veins were studied. The lower limb veins were divided into 5 segments:CFV,SFV,PPV,PTV and SFJ. The CVI limbs were also examined by phylebography.
方法：40条正常和30条慢性静脉瓣功能不全（CVI）下肢进行了CDFI检查，将下肢静脉分为股总静脉（CFV）、股浅静脉（SFV）、?静脉（PPV）、胫后静脉（PTV）和隐股连接部（SFJ）五个节段。
5.Because pressing of arteries and veins increased the impact to blood-vessel greatly,this is, make easy exhaustion mixes the stretch ingredient of tube wall rupture, easy development is aneurism and possible burst, at the same time of hemal wall inside film is injured easily and bring about sclerosis of arterial congee appearance and thrombosis, the hemal sclerosis that and be pressed with wide arteries and veins coexists and diastolic pressure are too low return burden of can aggravating heart and blood of influence coronal arteries and veins to offer.
这是因为脉压大就增加了对血管的冲击，使管壁的弹性成分轻易疲惫和断裂，易发展为动脉瘤并有可能破裂，同时血管壁的内膜轻易损伤而导致动脉粥样硬化及血栓形成，并且与宽脉压并存的血管硬化及舒张压过低还会加重心脏负担和影响冠脉血供。
6.50 cases underwent parenteral nutrition throught central veins (CV-TPN), 52 cases underwent parentera nutrition through peripheral veins (PV-TPN), all of the total nutrition admixture (TNA) were mixed thoroughly in PVC 3 liters package and infused into patients slowly.
通过中心静脉肠外营养（CV－TPN）50例，周围静脉肠外营养（PV－TPN）52例，均应用3升营养袋匀速滴入全合一营养液（TNA）。
7.Properties:a significant astringent effect, useful for inflamed and tender skin conditions, such as eczema. It is also valuable for damaged facial veins, varicose veins and hemorrhoids.
特性:具极佳的收?a作用,对发炎及敏感的皮肤,如湿疹有舒缓作用。对治疗面部微血管破裂、静脉曲张及痔疮也有很好的疗效。
8.Connecting branches to the dorsal of the finger side were observed. The superficial palmar digital veins join together in wed and drain into the dorsal palmar veins or the marginal vein arch of the palm.
指掌侧浅静脉在中线两侧走向指根部，在指蹼处邻指掌侧浅静脉汇合构成头间静脉，向背侧注入手背面的静脉，或注入手掌面远侧缘的边缘静脉弓。
9.Leaves ternate; leaflets papery or nearly leathery, ovate to ovate-elliptic, 6-15 cm long and 3-7 cm wide, apex abruptly acuminate, base rounded to subcordate, entire, both surfaces glabrous; basal veins 3, lateral veins 4- or 5-paired, conspicuous on both surfaces; petiolules 1.5-2 cm long, glabrous.
叶为三出复叶；小叶纸质或近革质，卵形至卵状椭圆形，长6-15厘米，宽3-7厘米，先端突尖，基部圆形至近心形，全缘，两面无毛；常有基出3出脉，侧脉4-5对，两面均明显；小叶柄长1.5-2厘米，无毛。
10.Results Compared with the condition before operation,the FPP decreased 3.2±0.4 mmHg,the quantity of blood flow of portal veins from 1104 ml/min dropped to 793 ml/min,and that of splenic veins from 897 ml/min dropped to 355 ml/min.
门脉血流量及脾静脉血流量均下降 ,门脉血流量由 110 4ml/min降到 793ml/min ,脾静脉血流量由 897ml/min降到 35 5ml/min。
