[Objectives]To investigate the effect of METTL3 on the malignant biological behaviors of uveal melanoma cells and to verify whether this effect is related to m6A methylation.[Methods]Uveal melanoma cell models with METTL3 knockdown,overexpression,and point mutations at m6A-related catalytic sites were constructed via lentivirus transfection.Transwell assays were used to assess cell migration and invasion;CCK8 assays were used to measure cell proliferation and flow cytometry was used to analyze apoptosis and cycle changes.[Results]The proliferation,migration and invasion abilities of C918 and MUM-2B cells with METTL3 knockdown were significantly decreased(P<0.001),while the apoptosis rate was increased.The proportion of cells in G1 phase significantly increased,whereas the proportion in the S phase significantly decreased.Cells overexpressing METTL3 showed significantly enhanced proliferation,migration and invasion abilities(P<0.001),along with a decreased apoptosis rate.In C918 cells,the proportion of cells in G1 phase decreased significantly,while the proportion in S phase increased significantly.The cell cycle distribution of MUM-2B cells did not change remarkably.Following point mutation of m6A-related catalytic sites,cell proliferation,migration and invasion decreased,and the apoptosis rate increased.In MUM-2B cells,the percentage of cells in G1 phase significantly increased;the percentage in S phase significantly decreased and the percentage in G2 phase slightly decreased.In C918 cells,the percentage of G1 phase cells significantly increased,with no significant changes in the proportions of S and G2 phases.[Conclusions]The proliferation,invasion and metastasis of uveal melanoma cells were positively correlated with the expression of METTL3,while the apoptosis rate was negatively correlated.Changes in METTL3 levels differentially affect the cell cycles in different cell lines.The effects of METTL3 on the proliferation,migration and invasion of uveal melanoma cells are related to m6A methylation modification.

Objective:To investigate the association between the metabolic score for visceral fat(METS-VF)and sarcopenia in older adults in China.Methods:A retrospective cohort study was conducted.A total of 1 262 participants aged ≥60 years old who did not diagnose with sarcopenia in 2011 and had complete follow-up data in 2015 were selected from the China health and retirement longitudinal survey(CHARLS). Participants were divided into the low METS-VF group (n=621)and the high METS-VF group (n=641), and then the corrleation between METS-VF and sarcopenia was analyzed.Results:The inverse probability of treatment weighting(IPTW)was used to balance all covariates between the low METS-VF group and high METS-VF group.The results showed that 30 participants in the low METS-VF group and 47 participants in the high METS-VF group were diagnosed with sarcopenia, with prevalence rates of 4.83%(30/621)and 7.33%(47/641), respectively.The difference in the prevalence of sarcopenia between the two groups was statistically significant after IPTW ( χ2=3.934, P=0.048, SMD=0.150). Logistic regression analysis showed that, after adjusting for various confounders, high METS-VF was significantly associated with an increased risk of sarcopenia in older adults( OR=2.130, 95% CI: 1.294~3.572, P=0.003). Subgroup analyses further indicated that individuals without cardiovascular disease had a relatively higher risk of sarcopenia( P for interaction=0.032). Conclusions:METS-VF is associated with an increased risk of sarcopenia in older adults in China, and its predictive and diagnostic value warrants further investigation.

Objective:To analyze the disease burden and changing trend of pancreatic cancer in our country from 1990 to 2021, and predict the incidence and mortality trends of pancreatic cancer from 2022 to 2036.Methods:Utilizing the data from the Global Burden of Disease 2021 Study, the age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), and disability-adjusted life rate (DALY) of pancreatic cancer in our country from 1990 to 2021 were evaluated. DALY is calculated by adding the number of years of life lost due to pancreatic cancer to the years of life lost due to disability. The Joinpoint model was used to calculate the average annual percentage change (AAPC), the age-period-cohort model was applied to control the influence of age, period and birth cohort, and the Bayesian age-period-cohort model was used to predict the incidence and mortality trends of pancreatic cancer in our country from 2022 to 2036.Results:Compared with 1990, the data of ASIR, ASMR and age-standardized disability-adjusted life years (DALY) rates of pancreatic cancer in our country in 2021 all increased, and the increase in men was more significant than that in women. The peaks of morbidity and mortality in 1990 and 2021 were both occurred in the elderly. The incidence rate, mortality rate and changes of men in all age groups were higher than those of women. The changes in the age-standardized DALY rate were mainly reflected in the male population. The first peaks of the age-standardized DALY rate in 1990 and 2021 both occurred at the age of 70-74, and the second peak of the age-standardized DALY rate in 2021 shifted to the age of 85-89. The peak rate of age-standardized DALY in females is earlier than that in males. The AAPC of ASIR and ASMR for all genders of pancreatic cancer in our country from 1990 to 2021 was 0.72 (95% CI: 0.50-0.94, P<0.001) and 0.56 (95% CI: 0.31-0.82, P<0.001), respectively, and the difference was statistically significant. In our country men with pancreatic cancer, ASIR (AAPC=0.89, 95% CI: 0.68-1.10, P<0.001) and ASMR (AAPC=0.71, 95% CI: 0.49-0.93, P<0.001) were compared with ASIR (AAPC=0.48, 95% CI: ) in women. 0.22-0.73, P<0.001) and ASMR (AAPC=0.33, 95% CI: 0.08-0.58, P=0.010) increased rapidly, and the difference was statistically significant. The ASDR of all genders showed an upward trend (AAPC=0.36, 95% CI: 0.18-0.54, P<0.001), and the difference was statistically significant. The incidence rate and mortality rate of all genders are on the rise. When the age of the population is over 60 years old, the incidence and mortality of specific diseases show an upward trend with the delay of the birth cohort. It is expected that from 2022 to 2036, the ASIR and ASMR of both men and women will increase annuallyand eventually double. Conclusion:From 1990 to 2021, the burden of pancreatic cancer in our country has generally shown an increasing trend, and it is expected that the disease burden will further increase in the future.

Lactic acid bacteria(LAB) have biological functions such as nutrition,bacteriostasis and immune regulation,which play important roles in the fields of food,agriculture and animal husbandry,industry,medicine and so on. At present,in the clinical application research of LAB,the focus of attention is on gastrointestinal diseases,urinary tract infections,allergic rhinitis,anti-tumor,etc.,but there are few introductions to the research progress of LAB in ocular application. In addition to regulating inflammation,the mechanism of action of lactic acid bacteria in the treatment of eye diseases is also affected by different mechanisms,which can be divided into direct and indirect effects. This article reviews the application of lactic acid bacteria in ocular surface diseases,fungal keratitis,lens and retinal diseases,summarizes and summarizes lactic acid strains and their related mechanisms,compares the differences of different lactic acid strains in the treatment of ophthalmic diseases. The in vitro,in vivo and clinical evidence of lactic acid bacteria in ophthalmic research are summarized,and the use of lactic acid bacteria in the treatment has high safety. The application of ophthalmic diseases has shown significant innovation and clinical significance,broadened the application scope of lactic acid bacteria in ophthalmology,and provided new ideas for future clinical treatment.

Objective To investigate the effect of bear bile powder(BBP)and ursodeoxycholic acid(UDCA)on preneoplastic lesions of hepatocarcinoma,using short-term carcinogenesis bioassay models.Methods Forty 6-week-old male SD rats were divided randomly into control,diethylnitrosamine(DEN),DEN+BBP(200 mg/kg),and DEN+UDCA(30 mg/kg)groups.All rats,except for the control group,were injected intraperitoneally with 100 mg/kg DEN once a week for 3 weeks.Rats in the DEN+BBP and DEN+UDCA groups also received oral BBP 200 mg/kg or UDCA 30 mg/kg suspended solution,respectively,daily from the beginning to the end of the experiment.Results There were no significant differences in body or liver weights between the DEN,DEN+BBP,and DEN+UDCA groups.DEN treatment increased the accumulation of malondialdehyde(MDA),decreased superoxide dismutase(SOD),and reduced glutathione(GSH)activities in liver tissue,while UDCA enhanced SOD and GSH activities and decreased MDA accumulation in liver tissue.In contrast,BBP exerted these antioxidant effects in serum.The number and area of glutathione S-transferase placental(GST-P)type-positive lesions and the Ki-67-positive cell ratio were significantly lower in the DEN+BBP and DEN+UDCA groups than in the DEN group,especially in the DEN+UDCA group.UDCA significantly increased Caspase-9 mRNA expression compared with the model group.Conclusions BBP and UDCA have significant inhibitory effects on preneoplastic lesions of hepatocarcinoma induced by DEN,and both have antioxidant effects on DEN-induced oxidative stress.The antioxidant mechanisms of BBP and UDCA differ,however,and further research is needed to determine the roles of the antioxidant effects in their anticancer mechanisms.
