"Compared with nonuse of hormone therapy, oral conjugated equine estrogen therapy increases the risk of venous thrombosis dose-dependently, esterified estrogen does not influence venous thrombosis risk, and the use of any estrogen in combination with medroxyprogesterone acetate increases risk as well," the authors write."If replicated, these findings for venous thrombosis may have implications for the choice of hormone in treating menopause-related vasomotor symptoms in perimenopausal and postmenopausal women."

Smith博士同时指出，相较於非荷尔蒙使用者，口服结合性雌激素不论剂量高低都会提高静脉栓塞的风险，脂化雌激素对静脉栓塞并不会造成影响；任何雌激素，只要伴随medroxyprogesterone acetate，都会提高静脉栓塞的风险；如果本项试验适用，就可以选择正确的荷尔蒙疗法，以治疗更年期及停经期妇女的血管舒缩症状。

Methods Taking 25mmHg as standard of leg venous hypertension, by means of triple integral, the optimal pressures against venous hypertension were worked out and four layer bandage was designed in the purpose of sustained pressure regulated compression for the healing of venous ulcers.

Results :The deep formal vein,formed by the perforating venous trunk and tributaries of gracilis muscle,converged into the femoral vein 8.6±0.9 cm below the midpoint of inguinal ligament.Its truck was 2.6±0.5 cm long and 6.9±1.1 mm in diameter.In 29 cases,there was 1 valve proximal to the abouchement of the first perforating vein.The deep femoral vein collected the venous blood of the thigh and the knee,the superficial venous blood of the shank.

结果：股深静脉由穿静脉主干及股薄肌支汇合而成，汇入股静脉处位于腹股沟韧带中点下8.6±0.9 cm，主干长2.6±0.5 cm，外径6.9±1.1 mm，29侧各有一个瓣膜位于第一穿静脉汇入处近侧，股深静脉通过其属支收集大腿外侧、后侧、内侧深部及浅静脉回流，并收集膝部深、浅静脉及小腿浅静脉回流。

Laser-induced chorioretinal venous anastomosis is a new and effective treatment for RVO, but serious complications limited its use in the clinic.

激光诱导脉络膜视网膜静脉吻合术（chorioretinal venous anastomosis，CRVA）是一种新的有效的治疗方法，但因能引起较严重的并发症，限制了其在临床上的普遍应用。

Creating chorioretinal venous anastomosis potentially offers a means of permanently bypassing the site of obstruction to venous outflow, to recovery the retinal blood circulation and to reduce the retinal ischemia. It is one of the methods curing the reason of CRVO and is demonstrated effective in non-ischemic CRVO patients using laser-induced chorioretinal venous anastomosis. Patients with ischemic CRVO have more severe situations and high risk factors of later neovascular complications occuring, the surgery of via a pars plana vitrctomy combined chorioretinal venous anastomosis can be the newest attempting treatment.

其发病机理和病因目前仍未完全阐明，也没有有效的治疗措施；除常规的药物和针对新生血管并发症的视网膜光凝治疗以外，近年来开展的各种旨在重建或恢复视网膜血液循环的激光和手术治疗方法正日益成为眼科界关注的焦点；利用建立脉络膜视网膜静脉吻合途径，使被淤滞的静脉血流经由脉络膜血管流出眼外，促进或者恢复视网膜血液循环，减少视网膜缺血缺氧状态的发生，是多途径CRVO对因治疗的方法之一。

Objective To investigate the significance of imageology diagnosis on cranial venous sinus thrombosis in ophthalmologic clinical practice.

目的 探讨影像学诊断在首诊于眼科颅内静脉窦血栓（cranial venous sinus thrombosis， CVST）形成中的意义。

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.

本研究结果显示，(1)单独应用TTE作为影像学引导进行冠状窦电极导管置放的成功率为93.8％～96.7％，并且应用TTE作为影像学引导放置专用冠状窦电极导管和普通电极导管的成功率和放置时间在统计学上无显著差异；(2)TTE作为影像学引导，除过度肥胖患者外，可完全替代X线引导进行冠状窦电极导管置放，包括鞘管和扩张管的放置、指引导丝在静脉而非动脉内的证实均可由TTE完成引导，且较X线C型臂有一定优越性；(3)TTE结合普通X线胃肠透视机作为影像学导引，可顺利完成心内电生理检查时导管的安全到位，而不需昂贵的X线C型臂，可将心内电生理检查扩大到广大的基层医院；(4)TTE较X线更易和更早期发现介入治疗的并发症如急性心包填塞等，对并发症的防治甚至挽救病人的生命至为重要；(5)动物实验研究表明，TEE可引导射频导管消融术时大头电极导管成功到位。

Objective:To provide anatomic basis for precaution and treatment of the massive hemorrhage of venous plexus of presacral region in Mile's operation.

摘 要：目的：研究骶前区静脉丛(Venous plexus of presacral region，VPPSR)的解剖学特点，为骶前区静脉破裂大出血的防治提供解剖学基础。

Results According to morphology, there were 3 types of superficial venous trunks in the flaps:"I" type,"Y" type and branch type. All types of the superfical venous trunks were the major passages in the venous drainage of the flaps. If the superficial venous trunks were occluded in pedicles, the venous drainage of the flaps almost stoped.

结果：根据形态可将逆行皮瓣中的浅静脉千分为3种类型：&I&形，&Y&形和树枝形，各种类型的浅静脉干都是皮瓣静脉逆向回流的主要通道，如果在蒂部将浅静脉干闭塞，皮瓣的静脉回流基本停滞。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
