Background:Liver transplantation(LT)is the best treatment for patients with hepatocellular carcinoma(HCC).However,the surgical technique needs to be *** present study aimed to evaluate the“no-touch”technique in ***:From January 2018 to December 2019,we performed a prospective randomized controlled trial on HCC patients who underwent *** patients were randomized into two groups:a no-touch technique LT group(NT group,n=38)and a conventional LT technique group(CT group,n=46).Operative outcomes and survival in the two groups were ***:The perioperative parameters were comparable between the two groups(P>0.05).There was no significant difference between the two groups in disease-free survival(DFS)(P=0.732)or overall survival(OS)(P=0.891).Of 36 patients who were beyond the Hangzhou criteria for LT,the DFS of the patients in the NT group was significantly longer than that in the CT group(median 402 vs.126 days,P=0.025).In 31 patients who had portal vein tumor thrombosis(PVTT),DFS and OS in the NT group were significantly better than those in the CT group(median DFS 420 vs.167 days,P=0.022;2-year OS rate 93.8%vs.66.7%,P=0.043).In 14 patients who had diffuse-type HCCs,DFS and OS were significantly better in the NT group than those in the CT group(median DFS 141 vs.56 days,P=0.008;2-year OS rate 75.0%vs.33.3%,P=0.034).Multivariate analysis showed that for patients with PVTT and diffusetype HCCs,the no-touch technique was an independent favorable factor for OS(PVTT:HR=0.018,95%CI:0.001-0.408,P=0.012;diffuse-type HCCs:HR=0.034,95%CI:0.002-0.634,P=0.024).Conclusions:The no-touch technique improved the survival of patients with advanced HCC compared with the conventional *** no-touch technique may provide a new and effective LT technique for advanced HCCs.

Based on quantitative structure-property relationship （QSPR） of organic compounds, the molecular connectivity indices of 21 phthalic acid ester compounds were extracted. Relationship between the physicochemical properties （n-octanol/air partition coefficient, vapor pressure, water solubility） and the molecular connectivity indices of phthalic acid ester compounds have been established by multiple linear regression （MLR） method. The results showed that the zero-order valence connectivity index （0Xu） is the topology parameter which affects octanol/water partition coefficient and water solubility, and the topology parameter which affects vapor pressure is the first-order connectivity index （1X）. This indicated to a certain extent_that the molecular connectivity indices can be well used to express the quantitative relationship between the physicochemical properties and structure descriptions of phthalic acid ester compounds. The models constructed have good robustness and highly predictive capability.
