The main obstacle of deepening reform in the new era is the solidification of interests, so breaking through the solidification of interests has become the key to the success of deepening reform. At present, the solidification of interests in China is mainly manifested in the following aspects: the solidification of interests caused by the internalization of profit of state-owned enterprises, and the rigidity and corruption in state-owned enterprises, the solidification of interests caused by the subordination of collective land property rights to state-owned land property rights, the solidification of interests caused by the too-big-to-fail real estate market and the tendency of stratum solidification caused by intergenerational transmission of income gap between urban and rural areas and strata. To break through the solidification of interests, it is necessary to carry out Kaldor improvement so that some groups can make a concession to improve the overall welfare of society. This paper gives the exploratory path of breaking through the solidification of interests, such as realizing the universal sharing of state-owned capital gains through legislation, breaking the solidification of interests of land system by realizing the equality of property rights between collective land and state-owned land, breaking through the interest solidification of the real estate market by incorporating the ratio of house price to income into the performance evaluation index of local governments, and restraining the tendency of stratum solidification by improving social mobility.

Effects of starvation on the type and distribution of mucus cells in the digestive tract of Nibea albiflora were evaluated by Alcian Blue/Periodic acid-Schiffs staining (AB-PAS). The experimental fishes were divided into four groups. Control group (S0) was fed with formulated diets to satiation twice a day during the experiment. The other three groups were deprived of feed for 10 (S10), 20 (S20), and 30 (S30) days. Results showed that the total number of mucus cells in the oropharyngeal cavity decreased significantly during the experiment, while no significant differences were observed in the hindgut. In S10 fishes, mucus cells in oesophagus decreased initially and then stabilised, whereas the total number of mucus cells in the foregut decreased significantly (p<0.05). Type I, II and IV mucus cells significantly decreased in all parts of the digestive tract of starved fishes (p<0.05). Type IV mucus cells were the most severely affected cells which even disappeared in the digestive tract after ten days of starvation. However, type III mucus cells containing mainly neutral substances increased significantly during starvation stress (p<0.05).
