In such patients we developed a parenchymasparing one-step approach, that includes extrahepatic right portal vein ligation accompanied by en bloc resection only of segments 7, 8 and 4a and resection of the right and middle hepatic veins. The technique was applied in 3 patients with normal liver function, where according to the preoperative computed tomography the volume of segments 1, 2 and 3 ranged between 17% and 20% of the total liver volume. In all patients liver biochemistry improved rapidly postoperatively and a doubling of volume of segments 1, 2 and 3 was achieved by the third postoperative week, as extrahepatic right portal vein ligation ameliorated reperfusion injury of the remaining segments 5 and 6 and induced hypertrophy of segments 1, 2, 3 and 4b. There was no mortality or long-term complications.Patients are alive and free of disease 74, 50 and 17 months after the operation, respectively. We propose that the term ＂extended upper right sectionectomy＂ may be considered for the en bloc resection of segments 7, 8 and 4a, in future revisions ofthe Brisbane 2000 terminology of hepatic anatomy and resections.展开更多

[Methods]A total of 60 patients with posttraumatic knee osteoarthritis in early stage in Affiliated Hospital of Shannxi University of Chinese Medicine from January 2015 to December2017 were selected and randomly divided into the control group( n = 30) and the observation group( n = 30). The control group was given oral administration of glucosamine hydrochloride capsules for 6 courses of the treatment. The observation group was using the activating blood circulation to resolve blood stasis therapy for 6 courses of treatment. The recovery of traumatic knee osteoarthritis and the symptom of traditional Chinese medicine( TCM) in 2 groups was compared before and after treatment. The symptoms and the quantitative assessment rating scale of knee osteoarthritis,the pain index of knee and the TCM symptom scores were recorded in both groups. And the synovial fluid and serum of patients were collected to detect the expression of matrix metalloproteinase. [Results]The symptoms and the quantitative assessment rating scale of knee osteoarthritis,the pain index of knee and TCM symptom scores of the 2 groups in the 1 st week,the 12 th week and the 24 th week after the treatment were significantly lower than those before the treatment,and the difference was statistically significant( P < 0. 05). Two therapeutic methods had certain therapeutic effects on the recovery from traumatic knee osteoarthritis,and could significantly improve the TCM syndrome. There were better therapeutic effects on oral decoction of traditional Chinese medicine than oral glycosaminoglycans hydrochloride capsules on treating traumatic knee osteogenesis( P < 0. 05). The expression level of MMP3 was decreased significantly in both groups( P <0. 001),while the expression level of MMP13 had no significant change in both groups( P >0. 05). The expression level of MMP1 was decreased significantly in the observation group( P < 0. 001),but there was no significant change in the control group after treatment( P >0. 05). [Conclusions]Two treatment methods have been effective in this clinical study. We found that the expression level of MMP3 was decreased significantly after treatment in 2 therapies,which can be clinically applied.展开更多
