Septic shock due to obstructive suppurative cholangitis secondary to choledocholithiasis was diagnosed. Anemia was also present,and upper gastrointestinal tract endoscopy revealed blood emerging from the Papilla of Vater.The cause of the anemia was identified as haemobilia.Angiography showed a small aneurysm over the artery on segment 3(A3) .The cause of the haemobilia was suspected to be the bleeding into the biliary tree from this aneurysm.Because the patient's general condition was poor,minimally invasive therapy was needed.Transcatheter arterial embolization(TAE) was selected initally.Later,lateral sectionectomy was performed in order to remove the aneurysm on A3. No surgical complication occurred and,after surgery,no haemobilia was identified.In conclusion,a twostage treatment,namely,surgery following TAE,is recommended for patients in a physically poor condition who have haemobilia due to intrahepatic aneurysm.展开更多

By adopting the two stage aerobic process, the COD Cr in PTA wastewater could be reduced from 4000—6000 mg/L to below 100 mg/L; the COD loading in the first aerobic tank could reach 7 0 to 8 0 kgCOD Cr /(m 3·d) and that of the second stage was from 0 2 to 0 4 kgCOD Cr /(m 3·d). Further researches on the kinetics of substrate degradation were carried out.展开更多

The results show that with increasing the solution treatment temperature (T_s), two way memory effect (TWME) decreases continuously and temperatures of martensite and reverse, martensite transformations (MR) rise, but the temperature of R start trans- formation (parent→R) does not change. The results of the internal friction measurements indicate that when T_s=1073 K, internal friction peaks of MR and P→R transformations are larger than those of the specimens after solution-treatments at 973 and 1173 K. With increasing T_s, the de- crease of TWME can be attributed to that the defect stress field caused by the rolling fades out grad- ually and preferential martensite variants, which fit into the defect stress field, decrease. The changes of transformation temperatures and internal friction peaks with T_s are closely related to the change of defect numbers.展开更多
