ABSTRACT
Objective To investigate the efficacy of transcatheter selective cystic arterial infusion chemotherapy embolization in the treatment of invasive bladder cancer with hemorrhage.Methods 81 cases of with invasive bladder cancer and hemorrhage treated by superselective intervention in hospital were selected,as well as postoperative complications and tumor volume changes were recorded in followG up.Results The success rate of intubation and embolization was 100%,the immediate hemostasis rate was 97.53%,and the preoperative bladder tumor volume (4.08±1.66)cm was significantly larger than that of the six months after surgery (3.45±1.33)cm.Conclusion Superselective cystic arterial perfusion embolization is a safe and effective treatment for patients with invasive bladder cancer complicated with hemorrhage.

ABSTRACT
Objective To investigate the clinical curative effect and significance of partial splenic artery embolization (PSE) for the treatment of patients with hypersplenism at high altitude region. Methods The clinical data of 66 patients with cirrhosis complicated by portal hypertension and hypersplenism, who lived in Xining City of Qinghai Province, the high altitude region in China, and were admitted to authors' hospital during the period from March 2015 to December 2016 to receive PSE, were retrospectively analyzed. White blood cell (WBC) count, red blood cell (RBC) count and platelet (PLT) count were calculated at one day before operation as well as at one, 7, 30 and 90 days after operation. Results The technical success rate of PSE was 100％. The mean WBC count determined at one, 7, 30 and 90 days after PSE was obviously different from that determined at one day before PSE, the differences were statistically significant (P＜0. 05). Conclusion For the treatment of patients with cirrhosis complicated by portal hypertension and hypersplenism, who live at high altitude region, PSE has reliable curative effect, therefore, this therapy is worth promoting in clinical practice.

ABSTRACT
At present,the combined interventional therapy that is based on transcatheter arterial chemoembolization (TACE) technique can control the progression of primary hepatocellular carcinoma (PHC)in different degrees,at the same time the clinical objectives,such as relieving portal hypertension,eliminating portal vein occlusion,controlling refractory ascites and lowering upper gastrointestinal bleeding probability,can be reliably achieved.Thus,the quality of life of the patients can be effectively improved and the survival time will be reliably prolonged.This paper aims to make a comprehensive review about the medical articles concerning TACE combined with other interventional therapies for PHC complicated by portal vein tumor thrombus,which have been published both at home and abroad in recent years,in order to provide practical help for clinical diagnosis and treatment of PHC.
ABSTRACT
Drought is a worldwide problem, seriously influencing plant (crop) productivity. Wheat is a stable food for 35% of the world population, and moreover, about 60% of land area on the globe belongs to arid and semiarid zone. Wheat drought resistance is a multi-gene controlling quantitative character and wheat final production in field is realized mainly by physiological regulation under the condition of multi-environmental factor interaction. Exploring drought resistance physiological mechanisms for different wheat genotypes is of importance to finding new drought resistance gene resources and conventional breeding, and the basis for wheat drought resistance biotechnological breeding and platform. Photosynthesis is the main component for physiological machinery of wheat assimilates conversion and wheat production. Investigation on photosynthetic characteristics of different wheat genotypes at soil water deficits also has other implications for refine physiological regulation of photosynthesis in fields and field management of crops in arid and semiarid areas. By pot-cultivating experiments, investigation of photosynthesis for 10 wheat genotypes at seedling stage and tillering stage at soil water deficits (75%FC, 55%FC and 45%FC, respectively) was conducted. The main results were as followed: developmental stages influenced wheat photosynthesis greatly and tillering stage played more roles; there were significant difference in the main photosynthetic parameters, photosynthesis rate (Photo), stomatal conductance (Cond) and transpiration rate (Tr), among 10 wheat genotypes; general photosynthesis and drought resistance in different wheat genotypes was related much to their domesticated origin soil water environment and selected generations and there was a photosynthetic threshold effect in terms of different wheat genotypes at soil water deficits.
