This study aimed to investigate halofuginone's inhibitory effect and mechanism on the activity of hepatocellular carcinoma cells. HepG2 cells were used to detect the effects of halofuginone. After treatment, cell activity, cell migration, cell cycle, and cell apoptosis were detected by CCK-8, transwell, and flow cytometry, respectively. The expression levels of growth and metabolism-related factors such as citrate synthase (CS), ketoglutarate dehydrogenase (OGDH), and isocitrate deoxygenase (IDH) were detected by real-time quantitative PCR and Western blot. Compared with the control group, the activity of HepG2 cells was significantly inhibited by halofuginone (

As the country with the largest number of new cancer cases and deaths,China faces a serious situation with a large cancer population base,low relative survival rate,and low adherence to cancer screening.Neighboring Japan,which has the longest life expectancy in the world,has a much higher relative survival rate than China,despite having a similarly high cancer rate,due to its well-established system of cancer prevention and control.Being an Asian country,the major prevalent cancers in China and Japan are similar in spectrum and can be referred to more.This article introduces the construction of Japan's cancer life-cycle prevention and control system of"cancer prevention","cancer care",and"coexistence with cancer"starting from the three major goals of Japan's cancer prevention and control program,and focuses on the improvement of cancer screening in Japan and the improvement of cancer survival in China.It also highlights the means and methods used to increase the cancer screening rate in Japan,with a view to providing suggestions for cancer prevention and control in China.

There was no significant difference in the incidence of adverse drug effects between the two groups ( P>0.05). Conclusions:HFHD treatment for patients with renal anemia in MHD has better treatment effect than LFHD, which can effectively correct the anemia state of patients, improve the body iron metabolism response, reduce inflammatory response and improve kidney function, and has certain clinical application value.

Objective To investigate the expression characteristics of BRAF,RAS and TERT genes in ultrasound-guided fine needle aspiration specimens and their application value in the preoperative diagnosis of thyroid nodules.Methods A retrospective analysis was performed on 537 cases of fine needle aspiration speci-mens of thyroid nodules in the Aviation General Hospital.The cell smear and liquid-based cell section prepara-tion from each specimen conducted the Papanicolaou's stain and the results were interpreted according to the Bethesda grading system.The gene mutation situation in punctured tissues was analyzed by real-time quantita-tive PCR.Results There were 65 cases (12.10%) of Bethesda class Ⅰ nodules,153 cases (28.49%) of class Ⅱ,84 cases (15.64%) of class Ⅲ,9 cases (1.68%) of class Ⅳ,73 cases (13.59%) of class Ⅴ and 153 cases (28.49%) of class Ⅵ.There were 220 cases (40.97%) of BRAF V600E mutation,21 cases (3.91%) of NRAS mutation,6 cases (1.12%) of KRAS mutation and 2 cases (0.37%) of HRAS mutation.Among them,there was BRAF V600E and KRAS co-mutation in 1 case.BRAF V600E gene mutation had the correlation with cytological diagnostic results (P<0.05),BRAF V600E mutation was more likely to occur in younger ones (P<0.05),and BRAF V600E mutation was more common in males than in females (P<0.05).KRAS mutation was more likely to occur in nodules in the left lobe of the thyroid gland (P<0.05).Conclusion BRAF V600E gene mutation is the most common among thyroid fine needle puncture specimens,and the NRAS mu-tation is in the majority for RAS gene mutations.

Sarcopenia is a syndrome associated with decreased muscle mass,decreased muscle strength,and reduced physical performance. Due to multiple factors such as tumor metabolism,systemic inflammatory response,disease progression,and reduced physical activity associated with treatment itself,the risk of sarcopenia in patients with lung cancer is higher than that of the general population. Sarcopenia is closely related to the clinical outcomes,including increased risk for mortality,and significantly impacts patients' long-term quality of life and mental health. This study systematic reviewed the risk factors for sarcopenia in patients with lung cancer,its negative effects on clinical outcomes,long-term quality of life and mental health,and the interventions for sarcopenia. Given the significant impact of sarcopenia on patients with lung cancer,it is urgent to explore a multidisciplinary intervention model to improve their survival and quality of life.
