Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated death globally. Liver transplantation (LT) has emerged as a key treatment for patients with HCC, and the Milan criteria have been adopted as the cornerstone of the selection policy. To allow more patients to benefit from LT, a number of expanded criteria have been proposed, many of which use radiologic morphological characteristics with larger and more tumors as surrogates to predict outcomes. Other groups developed indices incorporating biological variables and dynamic markers of response to locoregional treatment. These expanded selection criteria achieved satisfactory results with limited liver supplies. In addition, a number of prognostic models have been developed using clinicopathological characteristics, imaging radiomics features, genetic data, and advanced techniques such as artificial intelligence. These models could improve prognostic estimation, establish surveillance strategies, and bolster long-term outcomes in patients with HCC. In this study, we reviewed the latest findings and achievements regarding the selection criteria and post-transplant prognostic models for LT in patients with HCC.

Traditional Chinese medicine(TCM), a treasure of the Chinese nation, contains abundant chemical components and demonstrates unique pharmacological activities, showing important values in clinical applications. With profound connotations and broad application prospects, TCM urgently needs us to further explore and conduct systematic research. Puerarin is a small-molecule natural isoflavonoid carbon glycoside extracted from plants of Pueraria. It is also the main active ingredient of Puerariae Lobata Radix, a Chinese herbal medicine with both medicinal and edible values. Puerarin has a variety of pharmacological effects such as blood pressure-lowering, anti-atherosclerosis, anti-ischemia-reperfusion injury, antithrombotic, anti-tumor, anti-inflammatory, liver-protecting, nerve cell-protecting, and intestinal microbiota-regulating effects. It is also an active ingredient that has been widely studied. This article comprehensively reviews the research progress in the pharmacological effects and molecular mechanisms of puerarin over the years, aiming to provide references and theoretical support for the in-depth research and development as well as clinical application of puerarin.

Liver diseases cannot be easily detected in the early stage， and although invasive diagnostic methods， such as liver biopsy， are relatively accurate， they tend to have a low degree of acceptance， which greatly limits the improvement in diagnosis and treatment techniques for liver diseases. Therefore， it is of great importance to search for new biomarkers and therapeutic targets. As an emerging biomarker for liquid biopsy， tRNA-derived small RNA （tsRNA） is abnormally expressed in various liver diseases including viral hepatitis， fatty liver disease， liver injury， and liver cancer， and it can affect the development and progression of liver diseases by regulating the biological functions such as gene expression， epigenetic regulation， and protein translation. This article reviews the origin， classification， and biological function of tsRNA， as well as the research advances in tsRNA as biomarkers and potential therapeutic targets for liver diseases， so as to provide ideas for the early diagnosis and treatment of liver diseases.

Objective:To compare the clinical and laboratory characteristics and survival between Chinese and Western patients with myelodysplastic neoplasms (MDS) .Methods:Clinical and laboratory data were collected from 1,464 primary adult patients diagnosed with MDS at the Institute of Hematology & Blood Diseases Hospital from August 2016 to June 2024. Collected data were retrospectively analyzed and compared with 2,191 patients from the International Working Group for the Prognosis of Myelodysplastic Syndromes (IWG-PM) .Results:Chinese patients were significantly younger (median age: 56 years vs. 72 years, P<0.001) and experienced more severe hematopenia ( P<0.001) compared with patients from the IWG-PM. Further, Chinese patients exhibited a higher percentage of isolated del (20q), +8, and complex karyotypes as well as a lower percentage of normal karyotypes, del (5q), and -Y ( P<0.001). Higher U2AF1, NRAS, and NPM1 mutation rates and lower ASXL1, SF3B1, and RUNX1 mutation rates were observed in Chinese patients than in participants from the IWG-PM ( P<0.05). No significant difference in overall survival (OS) was found between the two groups (median OS: 48 [95% CI: 40 - 56]months, vs. 45[95% CI: 40 - 49] months; P=0.449). Among participants aged ≤45 years, Chinese patients demonstrated more trisomy 8 ( P=0.070) and U2AF1 mutation ( P<0.001) and higher 4-year OS rate compared with those from the IWG-PM (75.5% vs. 62.1%, P=0.001). Among participants aged ≥70 years, Chinese patients exhibited more complex karyotypes but fewer del (5q) as well as more NPM1 but less SF3B1 and TET2 compared with those from the IWG-PM ( P<0.05). Chinese patients demonstrated shorter survival (median OS: 20 [95% CI: 13 - 27] months vs. 37 [95% CI: 32 - 42] months, P<0.001) . Conclusion:Chinese and Western MDS patients differ in age of onset, clinical features, and cytogenetic or molecular genetic abnormalities, with significant differences persisting in age-matched groups. Although the OS is similar, disparities exist in survival for younger and older patients between the two populations.

Objective:To investigate the association between pre- and post-treatment gene mutation profiles and clinical outcomes (treatment response and prognosis) in patients with myelodysplastic syndromes with excess blasts (MDS-EB) receiving hypomethylating agent (HMA) monotherapy.Methods:The clinical characteristics, treatment efficacy, and survival outcomes of 69 treatment-naive patients with MDS-EB who underwent next-generation sequencing (NGS) before treatment and completed at least 4 cycles of HMA monotherapy at the Institute of Hematology & Blood Diseases Hospital, CAMS & PUMC, between June 2016 and September 2023, were retrospectively analyzed.Results:① The cohort comprised 47 males and 22 females with a median age of 62 years (range: 41-80). Thirty-nine patients were classified as MDS-EB1 and 30 as MDS-EB2. The median number of treatment cycles was 6 (range: 4-35). The median follow-up duration was 22 months (range: 5-72), and the median overall survival (OS) was 32 months (95% CI: 27-43). ② The presence of DTA (DNMT3A, TET2, or ASXL1) mutations, signaling pathway mutations, transcription factor mutations, or splicing factor mutations before HMA treatment showed no significant association with the best response within 4 treatment cycles, duration of response (DOR), or OS. TP53 mutation status was significantly associated with DOR and shorter OS. The median DOR was 3 months (95% CI: 1-10) for patients with biallelic TP53 mutations, 10 months (95% CI: 3-34) for those with monoallelic TP53 mutations, and 16 months (95% CI: 8-27) in patients without TP53 mutations ( P=0.032). The median OS was 16 months (95% CI: 7-38), 15 months (95% CI: 6-40), and 35 months (95% CI: 14-91), respectively ( P<0.001). ③ Neither the Revised International Prognostic Scoring System (IPSS-R) nor the Molecular International Prognostic Scoring System (IPSS-M) could predict the best response within 4 treatment cycles or DOR in patients receiving HMA therapy. ④ Among patients without TP53 mutations, the median OS was 55 months (95% CI: 9-106) for the major clone significant clearance group ( n=14) and 31 months (95% CI: 16-184) for the major clone non-significant clearance group ( n=10) ( P=0.013). For patients who responded to HMA treatment and had significant major clone clearance, the 3-year OS rate reached (77.8±13.9) %. Conclusion:For MDS-EB patients receiving HMA monotherapy, single gene mutations, IPSS-R, and IPSS-M could not effectively predict treatment outcomes before therapy. However, for patients without TP53 mutations, monitoring the degree of major clone clearance by NGS during treatment may predict the long-term efficacy in MDS patients receiving HMA therapy.

Objective: To explore the current status of hyperopic reserve and its related factors among non-myopia preschool and primary school students aged 5 to 12 years in Guangdong Province, so as to provide a basis for formulating intervention strategies for the pre myopia stage of children. Methods: From October to December 2023, by using stratified cluster random sampling method, a survey on hyperopic reserve among preschool children and primary school students in Guangdong were conducted. And a total of 10 567 children from the senior class of kindergarten to the sixth grade of primary school who completed autorefraction measurements with and without cycloplegia and the questionnaire survey were included in the study. The prevalence characteristics of low hyperopic reserve among non-myopia children were analyzed, and multivariable Logistic regression was used to analyze the related factors. Results: The prevalence rate of low hyperopic reserve among 8 790 non-myopia children was 62.4%. The average spherical equivalent (SE) for children aged 5 to 12 years was 0.88 (0.25, 1.25)D, decreasing from 1.13 ( 0.75 , 1.50)D in senior kindergarten to -1.00 (-2.50, 0.38)D in sixth grade, with the difference was statistically significant ( H=2 475.3, P <0.01). Multivariable Logistic regression analysis, after adjusting for confounders including gender, urban and rural, and grade, revealed that parental myopia was a risk factor for low hyperopic reserve in the preschool stage (one parent with myopia: OR=1.62, 95%CI =1.35-1.93; both parents with myopia: OR=2.05, 95%CI = 1.66 -2.55); in the lower primary school stage, parental myopia (one parent with myopia: OR=1.46, 95%CI =1.27-1.68; both parents with myopia: OR=1.58, 95%CI =1.33-1.89), frequently or always reading or using electronic screens while lying down or on one s stomach ( OR=1.43, 95%CI =1.13-1.81), and never or occasionally maintaining a viewing distance of over 3 meters when watching TV/playing video games ( OR=1.34, 95%CI =1.04-1.72) were risk factors; in the higher primary school stage, failing to take a break every hour during near work ( OR=1.79, 95%CI =1.16-2.75) was a risk factor (all P <0.05). Conclusions The emmetropization of children aged 5-12 years in Guangdong Province is accelerated, and non-myopia children generally exhibit insufficient hyperopic reserve. The contributing factors for insufficient hyperopia reserve in non-myopia children vary across different educational stages, necessitating targeted precision interventions.

Objective:To explore the impact of plant and animal dietary behaviors on type 2 diabetes mellitus (T2DM) in older adults aged ≥65 in 18 longevity areas of China.Methods:The subjects were 5 223 older adults over 65 years old from the Healthy Ageing and Biomarkers Cohort Study (HABCS) in 18 longevity areas in China. Through a questionnaire survey and physical examination, information about their demographic characteristics, lifestyles, daily activities, self-health status, current diseases, and fasting venous blood were collected. Food Frequency and Questionnaire (FFQ) was used to collect data on food intake frequency. Based on the prior method, the plant-based diet index (PDI) and animal-based diet index (ADI) of 5 223 older adults were calculated. Subjects were divided into three groups (low-level group: PDI<39 or ADI<31, middle-level group: 39≤PDI≤42 or 31≤ADI≤34, high-level group: PDI>42 or ADI>34) by tertiles of PDI and ADI. Multivariate logistic regression was used to analyze the association between PDI and ADI and the risk of T2DM.Results:The average age of 5 223 subjects was (84.8±11.5) years, with the median ( Q1, Q3) of PDI about 41(38, 43) and the median ( Q1, Q3) of ADI about 33 (30, 35). The prevalence rate of T2DM was 16.41% (857/5 223). After adjusting for covariates, multivariate logistic regression showed that PDI was negatively associated with T2DM. Compared with the low-level group, the OR (95% CI) for T2DM in the high-level group was 0.83 (0.69-0.99). ADI was positively associated with T2DM, and compared with the low-level group, the OR (95% CI) for T2DM in the high-level group was 1.28 (1.06-1.55). For every one-point increase in PDI and ADI, the risk of T2DM decreased by 2% and increased by 3%, respectively, with the OR (95% CI) of 0.98 (0.96-1.00) and 1.03 (1.01-1.06), respectively. Conclusion:In Chinese older adults ≥65 years in 18 longevity areas, higher adherence to the plant-based behavior may be negatively associated with the risk of T2DM, while higher adherence to the animal-based behavior may be positively associated with the risk of T2DM.

Objective:To analyze the clinical characteristics, therapeutic responses, and survival outcomes of patients with lymphocytic variant hypereosinophilic syndrome (L-HES) .Methods:We retrospectively reviewed clinical data from 16 consecutive patients diagnosed with L-HES at the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences, between July 2019 and October 2024. A control group of 65 patients with idiopathic hypereosinophilic syndrome (iHES), diagnosed during the same period, was used for comparison. Clinical and laboratory characteristics, therapeutic responses, and survival outcomes were compared between the two groups.Results:The most frequently involved organs at presentation in patients with L-HES were the skin (75.0%), gastrointestinal tract (25.0%), respiratory tract (18.8%), lymph nodes (18.8%), heart (12.5%), and spleen (6.3%). Compared with iHES patients, patients with L-HES had a significantly higher incidence of skin involvement ( P=0.016), with no statistically significant differences observed in the involvement of other organs. No statistically significant differences were found in complete blood count parameters between the two groups. Multiparameter flow cytometry revealed that the median percentage of CD3 -CD4 + T cells in the peripheral blood of patients with L-HES was 4.08% ( IQR: 1.64%-32.78%), with a median absolute count of 0.10 (0.05-0.55) ×10 9/L. Serum immunoglobulin E (IgE) levels were significantly higher in the L-HES group than in the iHES group ( P<0.001). Clonal rearrangement of T-cell receptor genes was detected in 75.0% of patients with L-HES. After diagnosis, 14 patients with L-HES received glucocorticoids as first-line therapy, yielding an overall response rate of 92.9%. During glucocorticoid tapering, 11 patients experienced recurrent eosinophilia or worsening of clinical symptoms. Three patients received interferon-alpha as a second-line therapy, with two achieving complete remission. After a median follow-up of 16 months ( IQR: 8-28 months), one patient died of cardiac insufficiency 8 months after diagnosis, and no cases of lymphoma transformation were observed. The 2-year overall survival rate was (91.7±8.0) %, which did not significantly differ from that of the iHES group (96.2±2.6) % ( P=0.746) . Conclusions:Patients with L-HES generally have a favorable prognosis and are often characterized by skin involvement and significantly elevated serum IgE levels at diagnosis. They typically respond well to glucocorticoid therapy, although relapse is common during dose tapering. Interferon-alpha may serve as an effective second-line therapeutic option.
