Analysis on the Clinical Therapeutic Effect of Hepatic Artery Chemoembolization in the Treatment of Advanced Liver Cancer

Objective:To analyze the clinical efficacy of hepatic artery chemoembolization in the treatment of advanced liver cancer.Methods:124 patients with advanced liver cancer admitted to our hospital from September 2019 to November 2020 were selected as the research subjects of this paper.The patients with advanced liver cancer were divided into experimental group and control group.The control group was treated with radiofrequency ablation alone,and the experimental group was administered hepatic arterial chemoembolization.The improvement in physical indicators and the incidence of adverse reactions between the two groups were compared.Results:The alpha-fetoprotein(AFP)index and serum total bilirubin(TBIL)index of the experimental group were lower than those of the control group,and the alanine aminotransferase(ALT)index was higher than that of the control group.There were differences in the comparison of liver function indices between the two groups which were statistically significant.After treatment,there were 3 cases of fever,4 cases of vomiting,8 cases of bone marrow transplantation,4 cases of abdominal pain,2 cases of proteinuria,and 1 case of diarrhea occurred in the experimental group;whereas there were 6 cases of fever,8 cases of vomiting,14 cases of bone marrow transplantation,7 cases of abdominal pain,5 cases of proteinuria,and 6 cases of diarrhea occurred in the control group.The difference in incidence of adverse reactions between patients after different treatment interventions was statistically significant.Analyzing the remission rate of tumor diseases in patients,the remission rate of the experimental group was higher than that of the control group,and the difference in the remission rate between the two groups of patients was statistically significant.Conclusion:The implementation of hepatic arterial chemoembolization for patients with advanced liver cancer can promote the improvement of the patient's short-term treatment efficacy,enhance the liver functions of the patient,reduce the incidence of adverse reactions,improve the efficiency of the patient's body rehabilitation,and enhance the quality of life of the patient after treatment.

Elite sd1 alleles in japonica rice and their breeding applications in northeast China

The Green Revolution gene sd1 has been used extensively in modern rice breeding,especially in indica cultivars.However,elite sd1 alleles and related germplasm resources used for japonica rice breeding have not been identified,and extensive efforts are needed for japonica rice breeding to obtain new dwarfing sources.Data from MBKbase-Rice revealed seven sd1 haplotypes in indica and four in japonica rice.Two new sd1 alleles were identified in indica rice.In 295 japonica accessions from northeast Asia,except for the weak functional allele SD1-EQ,sd1-r was the major allele,reducing plant height in comparison with SD1-EQ.Japonica germplasm resources carrying reported sd1 alleles were identified by genotype searching and further verified by literature search,genealogical analysis,and d Caps markers.Pedigrees and geographic distribution showed that sd1-r is an excellent allele widely used in northern China and Tohoku in Japan,and sd1-j is commonly used in east China and Kyushu in Japan.Dongnong-and Xiushui-series cultivars carrying sd1-r and sd1-j,respectively,are essential branches of the backbone parents of Chinese japonica rice,Akihikari and Ce21,with the largest number of descendants and derived generations.In semi-dwarf japonica rice breeding,sd1-d was introgressed into Daohuaxiang 2(DHX2).Dwarf and semi-dwarf lines carrying sd1-d were selected and designated as 1279 and 1280,respectively,after withstanding typhoon-induced strong winds and heavy rains in 2020,and are anticipated to become useful intermediate materials for future genetic research and breeding.This work will facilitate the introduction,parental selection,and marker-assisted breeding,and provide a material basis for the next step in identifying favorable genes that selected together with the sd1 alleles in japonica backbone parents.
