AIM:To compare the prognoses of hepatocellular carcinoma(HCC)patients that underwent anatomic liver resection(AR)or non-anatomic liver resection(NAR)using propensity score-matched ***:Between January 2002 and December2010,268 consecutive HCC patients,including 110 and158 patients that underwent AR and NAR,respectively,were retrospectively enrolled in this ***-four patients from each group were selected and matched using logistic multivariate analysis followed by propensity score ***:In the whole analysis set,the histological background of the liver,liver function,and tumor marker levels differed significantly among the *** the overall survival(OS)and recurrence-free survival rates of the two groups did not differ significantly in the whole analysis set,the OS of the AR group was significantly longer than that of the NAR group after propensity matching(76.2±6.3 mo vs 58.9±6.3mo;P=0.0039).Although AR(HR=0.456,P=0.039)was found to be a prognostic factor in the univariate analysis,only vascular invasion(HR=0.228,P=0.002)and the hepatocyte growth factor level(HR=52.366,P=0.035)were subsequently found to be independent prognostic ***:AR conveys a survival advantage over NAR in specific subpopulations of HCC patients with tumors of less than 5 cm in diameter,single tumor,and good liver function.

The utilization efficiency of resources is one of the important factors affecting the development of modern agriculture. Using production function method and ratio analysis method,we carry out the horizontal comparison of the utilization efficiency of major agricultural resources such as arable land,agricultural machinery power and chemical fertilizer in Hebei Province and the national level,and the vertical comparison of the utilization efficiency of major agricultural resources between the prefecture-level cities in the province. The results show that the utilization efficiency of agricultural resources in Hebei Province is below the national average,and there are significant differences in the utilization efficiency of agricultural resources between the prefecture-level cities in the province.

According to the eco-efficiency theory, combined with agricultural production characteristics, I point out the environmental impact and substance energy consumption characteristics of agricultural production. Based on this, I establish the eco-efficiency evaluation indicator system for agricultural production, and conduct a comprehensive analysis on the agricultural eco-efficiency of 17 prefecture-level cities in Anhui Province, using data envelopment analysis method.
