Fall of blood pressure is in direct proportion to the resistance of blood flow,and the BP decreases significantly in the arteriole ,where the blood flow resistence is the biggest.

血压降落与血流阻力成正比，在血流阻力最大的微动脉段，血压降落最为显著。

Objective:to explore the evaluation of color doppler ultrasonography in differential diagnosis of renal cystic disease.methods:theultrasonographic finds of cystic renal cancer in 4 cases,renal cyst in 30 cases, renal tuberculosis in 3 cases,nephropyosis in 8 cases,renal hydatid in 2 cases were analyzed.compared with each other in size,shape,edge, echo of cyst wall and cyst water,intracapsular membrane,blood flood.results:two-dimensional and color ultrasonography are helpful in showing the characteristic of structure and blood flow.the signal of blood flow can be found in cystic wall.node of cystic wall and intracapsular membrane of cystic renal cancer.the rate ofintracapsular membrane and node of cystic wall is higher than nephropyosis,renal tuberculosis and cystic renal disease.

目的：探讨彩色多普勒超声在肾脏囊性病变鉴别诊断中的价值。方法：对临床和病理证实的4例囊性肾癌，8例肾脓肿，2例肾包虫，3例肾结核，30例肾囊肿的二维超声及彩色多普勒超声表现进行了分析，对每例病灶的大小、形态、边界、囊壁回声、囊液回声、囊内分隔及彩色血流的有无、性质进行比较。结果：二维超声和彩色多普勒超声可以反映肾脏囊性病变的结构特征及血流特征。

Ovarian stromal flow PSV, EDV and perifollicular vascularity are highly interrelated with ovarian response. Ovarian response will be improved when ovarian blood velocity increases and perifollicual blood flow is abundant. Follicular fluid VEGF level was obviously higher in poor responder group, which suggests VEGF be secreted increasing for compensating due to reduced ovarian stromal blood velocity and fewer perifollicular vascularity.

卵巢基质内血流的PSV、EDV和卵泡周血流分布、卵泡液VEGF水平与卵巢的反应性密切相关，卵巢基质内血流速度升高、卵泡周边血流丰富，有助于提高卵巢的反应性；低反应卵巢组卵泡液VEGF水平显著升高，推测是由于其卵巢基质内血流速度低，卵泡周血管分布少，导致VEGF代偿性分泌增加。

An increase in the blood flow velocity of internal jugular vein,the abnormal acoustic frequency and its spectrum of TCD were signs indicated that the blood stream of CCF were drained by the superior and/or inferior petrous sinuses.TCD could detect the superficial sylvian vein where the blood flow velocity increased when the cortical veins were the main veins draining CCFs.

异常眼静脉搏动征，血流反向是诊断CCF眼上静脉引流的可靠指标；颈内静脉流速增高，声频及频谱异常是CCF血流经岩上窦、岩下窦引流的征象；当以皮层静脉引流为主时，颅内常可检出流速增高的侧裂静脉。

Blood-cooling and blood flow-promoting drugs has the effect of prevention and treatment for the early radiation-induced lung injury, Middle-dose and high -doses group were better than small-dose, however theres no difference between them. Suggest that using the adequate doses of blood-cooling and blood flow-promoting drugs would not enhance the effects of prevention and cure for radiation-induced lung injury if the doses of drugs were aggrandized.

早期应用凉血活血方对放射性肺损伤有防治作用，大、中剂量组的防治效果明显好于小剂量组，但大、中剂量两组无差别，提示凉血活血方中剂量即为较理想有效剂量，剂量加倍而疗效并不增强。

The blood flow velocity of patients with subtentorial brain injury or metabolic or diffused brain disease have no obvious change. The moderate and deep coma patients, if their blood flow velocity of end systolic stage are lower than end diastolic stage, will lose the auto-regulatory function of cerebral blood vessels, as lead to a bad prognosis.

颅内幕下结构损害、代谢及弥漫性脑病患者脑血流变化不明显，中度昏迷及深昏迷患者出现收缩期末血流速低於舒张期末血流速多提示脑血管自动调节功能丧失、预后不佳。
