Objective To investigate the effect of routine ultrasound examination and interventional treatment of absolute alcohol in different types of liver cancer.Methods Thirty cases of liver cancer patients who were treated in the 3rd People' s Hospital of Yangquan from May 2010 to May 2014 were selected as ours subjects.They were performed ultrasound exam.The ultrasound characteristic was recorded.Patients were divided into intrahepatic cholangiocarcinoma (ICC) group (11 cases),hepatocellular cholangiocarcinom (HCC) group (14cases) and mixed cholangiocarcinoma group(5 cases) based on pathology results.Nine HCC postoperative recurrence patients and 7 ICC postoperative recurrence patients were treated with absolute alcohol and the clinical effect was observed.Results There were significant differences in the three groups in terms of gender,boundary definition and tumor location (x2 =8.01,6.16,7.32 ; P ＜ 0.05).While the distribution of ultrasound echo intensity was not statistically significant(x =3.44,P ＞ 0.05).The effective rate of interventional treatment of absolute alcohol in HCC patients was 88.89％,and 42.86％ in ICC group,and the difference was statistically significant (x2 =3.88,P ＜ 0.05).Conclusion The ultrasound characteristics of different pathological liver cancer are different.Ethanol interventional therapy on HCC patients is significantly better than the effect of ICC patients,suggesting that ICC postoperative recurrence patients can be treated combined with other methods to help improve the effect.

【Objective】 To analyze the height growth of children aged 6 - 15 years in Nanning, Guangxi Zhuang Autonomous Region, so as to provide evidence for the assessment of local children′s height development. 【Methods】 A total of 25 225 children aged 6 - 15 years were selected to get their physical examination data from 41 primary schools in Nanning by stratified cluster sampling method in December 2021.Then the height data were compared with the current domestic standards. 【Results】 The average height of boys in Nanning was lower than the national standard before the age of 10 years and 7 months, and the gap with the national standard gradually narrowed after the age of 10 years and 7 months. The average height of boys in Nanning City exceeded the national standard between the age of 11 years and 1 month and 13 years and 6 months, and then lagged behind the national standard again after the age of 13 years and 7 months. The mean height of girls in Nanning City was lower than the national standard height in several age groups, and it was more obvious before the age of 9 years and 7 months. The proportion of height ≤-2s,≤-s,≥ +s and ≥+2s in boys aged 6 to 15 years in Nanning City fluctuated from 2.59% to 6.04%, 12.09% to 23.43%, 7.18% to 18.79% and 0.93% to 3.14%, respectively; the total proportions were 4.56%, 17.46%, 11.35% and 1.74%, respectively; the minimum/maximum proportion values of each height group were at 11 years old /8 years old, 14 years old/8 years old, 8 years old/12 years old, and 6 years old/11 years old, respectively. The proportions of girls aged 6 - 15 years in Nanning City with height ≤-2s, ≤-s, ≥+s, and ≥+2s fluctuated from 2.06% to 5.19%, 9.35% to 25.15%, 8.21% to 15.80% and 1.23% to 3.49%, respectively; the total proportions were 3.38%, 16.91%, 11.97% and 2.29%, respectively; and the minimum/maximum proportion values of each height group were at 13 years old/6 years old, 12 years old/6 years old, 7 years old/12 years old, and 6 years old/11 years old, respectively. 【Conclusions】 The overall height level of children in Nanning is still lower than the national level, with short prepubertal basal heights, an earlier age of onset of accelerated pubertal height, and a shorter duration of accelerated pubertal height in boys. Strengthening pre-pubertal height management and emphasizing the onset and duration of children′s pubertal development, especially the height development of boys during puberty, can help improve the adult lifelong height of children in this region.
