[Purpose]To analyze the changing trends of the disease burden of liver cancer related to hepatitis B virus(HBV)globally and in China from 1992 to 2021.[Methods]Based on the Global Burden of Disease database in 2021,indicators such as the age-standardized incidence rate and mortality rate of HBV-related liver cancer globally and in China from 1992 to 2021 were collected.The Joinpoint regression model was used to analyze the changing trends of epidemiologi-cal characteristics,and the age-period-cohort model was adopted to analyze the impacts of age,period,and cohort factors on the incidence and mortality risks of HBV-related liver cancer globally and in China.[Results]From 1992 to 2021,the age-standardized incidence rate and age-standardized mortality rate of HBV-related liver cancer globally generally showed a trend of decreasing.The average annual percentage changes were-0.31％and-0.61％,respectively,and all the down-ward trends were statistically significant(both P＜0.05).During the same period,the average annu-al percentage changes of the age-standardized incidence rate and age-standardized mortality rate of HBV-related liver cancer in China were-0.45％and-0.90％,respectively,and all the downward trends were statistically significant(both P＜0.05).The results of the age-period-cohort model anal-ysis showed that from 1992 to 2021,the annual net drift rates of the incidence of HBV-related liver cancer globally and in China were-0.71％(95％CI:-0.84％～-0.57％)and-0.73％(95％CI:-1.01％～-0.44％),respectively.The annual net drift rates of the mortality were-1.15％(95％CI:-1.28％～-1.02％)and-1.42％(95％CI:-1.69％～-1.14％),respectively,all showing an over-all decline.The age effect showed that the risk of HBV-related liver cancer incidence in both the global and Chinese populations began to increase after 30 years of age,peaking in the 70～74 age group,while the risk of mortality surged after 40 years of age and peaked in the population aged 80 and above.The period effect indicated that the incidence and mortality risks were the highest from 1997 to 2001 and the lowest from 2017 to 2021.The cohort effect revealed that the inci-dence and mortality risks gradually decreased in populations born after 1962,with the 2007-2011 birth cohort having the lowest risks.The results of the Wald x2 test showed that there were statistically significant differences in the changing trends of the age,period,and cohort effects on the incidence and mortality of HBV-related liver cancer globally and in China(all P＜0.05).[Con-clusion]From 1992 to 2021,the age-standardized incidence rate and age-standardized mortality rate of HBV-related liver cancer showed a downward trend both globally and in China.The disease burden of HBV-related liver cancer in China was higher than the global level.The age-period-cohort model has revealed the historical changes in the incidence and mortality of HBV-related liver cancer.The current and future situation of the disease burden of HBV-related liver cancer is not optimistic.It is recommended to implement precise stratified interventions for populations of different ages,periods,and birth cohorts,and actively transform the prevention,treatment,and management strategies for HBV-related liver cancer.

Inguinal hernia is one of the most prevalent general surgical conditions affecting the elderly population.Currently, open or laparoscopic surgical repair represents the only curative approach.Among various surgical techniques, tension-free hernia repair via the preperitoneal space effectively addresses the complications associated with traditional surgical methods, such as excessive tension in the surgical area, postoperative pain and discomfort, and a subsequent decline in patients' quality of life.Nevertheless, a certain recurrence rate persists.This paper aims to highlight the insufficient research on preperitoneal hernia repair procedures within the field of hernia surgery and to conduct a comprehensive analysis of the primary factors contributing to postoperative recurrence.This analysis will be approached from three key perspectives: medical origins, individual patient variability, and the characteristics of the patch used.The goal is to provide a foundation for the theoretical framework and practical strategies aimed at reducing postoperative recurrence rates.

BackgroundIn recent years， the incidence of non-suicidal self-injury （NSSI） behaviors among adolescents has been increasing annually. Self-esteem and alexithymia are strongly associated with NSSI behaviors， and alienation is closely linked to both self-esteem and alexithymia. However， there is limited research on the relationship between alienation and NSSI behaviors among adolescents in China. ObjectiveTo analyze the relationship between alienation and NSSI behaviors among adolescents， and to explore the factors influencing NSSI behaviors in this population， so as to provide insights for the prevention and treatment of NSSI behaviors in adolescents. MethodsAdolescents admitted to the Department of Psychiatry and Psychology at the 923^rd Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from September 1， 2021 to March 1， 2023， who met the diagnostic criteria for NSSI in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）， were selected as the study group （n=60）. Concurrently， middle school students from Nanning were recruited as the control group （n=60）. Participants were assessed using Adolescent Self Harm Scale （ASHS）， Rosenberg Self-Esteem Scale （RSES）， Toronto Alexithymia Scale （TAS） and Adolescent Students′ Alienation Scale （ASAS）. Pearson correlation analysis was employed to examine the relationships between scale scores in the study group， and Logistic regression analysis was used to identify the influencing factors of NSSI behaviors among adolescents. ResultsThe RSES score of the study group was significantly lower than that of the control group （t=-7.033， P<0.01）. The TAS and ASAS scores of the study group were significantly higher than those of the control group （t=5.591， 8.124， P<0.01）. The ASHS score was negatively correlated with RSES score （r=-0.410， P<0.01） and positively correlated with ASAS score （r=0.555， P<0.01）. The RSES scores of the study group were negatively correlated with TAS and ASAS scores （r=-0.317， -0.590， P<0.05 or 0.01）. Logistic regression analysis showed that being female （OR=0.714， 95% CI： 0.042~0.709） was a protective factor for NSSI behaviors among adolescents， while high alienation （OR=1.028， 95% CI： 1.013~1.043） and residing in rural areas （OR=6.692， 95% CI： 2.038~21.967） were risk factors for NSSI behaviors among adolescents. ConclusionAlienation was positively correlated with NSSI behaviors in adolescents. Female adolescents had a lower risk of NSSI behaviors， while those with higher levels of alienation or residing in rural areas were more prone to NSSI behaviors. ［Funded by Self-financed Scientific Research Project of the Health Commission of Guangxi Zhuang Autonomous Region （number， Z20210656）； Self-financed Scientific Research Project of the Health Commission of Guangxi Zhuang Autonomous Region （number， Z-A20231057）］

Chronic heart failure （CHF） is the final stage of cardiovascular diseases. It is a complex syndrome， with dyspnea and edema as the main clinical manifestations， and it is characterized by complex disease conditions， difficult cure， and high mortality. Ferroptosis， a new type of programmed cell death， is different from other types of programmed cell death. Ferroptosis is iron-dependent， accompanied by lipid peroxide accumulation and mitochondrial shrinkage， becoming a hot research topic. Studies have confirmed that ferroptosis plays a key role in the occurrence and development of CHF. The regulation of ferroptosis may become a potential target for the treatment of CHF in the future. The theory of Qi deficiency and stagnation refers to the pathological state of original Qi deficiency and abnormal transportation and distribution of Qi， blood， and body fluid， which has guiding significance for revealing the pathogenesis evolution of some chronic diseases. We believe that Qi deficiency and stagnation is a summary of the pathogenesis of ferroptosis in CHF. Deficiency of Qi （heart Qi） is the root cause of CHF， and stagnation （phlegm turbidity and blood stasis） is the branch of this disease. The two influence each other in a vicious circle to promote the development of this disease. Traditional Chinese medicine （TCM） plays an important role in the treatment of CHF， improving the prognosis and quality of life of CHF patients. This paper explores the correlation between the theory of Qi deficiency and stagnation and the mechanism of ferroptosis in CHF. Furthermore， this paper reviews the mechanism of Chinese medicines and compound prescriptions in preventing and treating CHF by regulating ferroptosis according to the principles of replenishing Qi and dredging to remove stagnation， aiming to provide new ideas and methods for the treatment of CHF with TCM.

OBJECTIVE To analyze clinical switching patterns and reasons between bevacizumab biosimilar and originator drugs. METHODS The data were collected from 1 175 cancer patients treated with bevacizumab at Ruijin Hospital， Shanghai Jiao Tong University School of Medicine from January 1， 2018， to December 31， 2023. The patients were divided into originator group （n＝250） and biosimilar group （n＝925）. The switching rate， switching type and reasons of the two groups were compared. RESULTS There were no statistically significant differences in the switching rate， switching types， and the number of switches between the two groups （P＞0.05）. Single， one-way switches were the switching type in both groups. The proportion of patients in the biosimilar group who switched due to adverse events was significantly higher than originator group， while the proportion of patients who switched due to treatment costs was significantly lower than originator group （P＜0.05）. There were no statistically significant differences in the proportions of patients who switched due to efficacy and drug accessibility between the two groups （P＞0.05）. CONCLUSIONS The switching between bevacizumab biosimilar and the originator drugs mainly involves single， one- way switches. Treatment costs and drug accessibility are the main factors for the switches among users of originator drugs， while drug accessibility and adverse events are the main factors for the switches among users of biosimilar.

OBJECTIVE: To compare the clinical efficacy of jingjin needling combined with rehabilitation training and conventional acupuncture combined with rehabilitation training for post-stroke spastic paralysis. METHODS: A total of 60 patients with post-stroke spastic paralysis were randomly divided into an observation group and a control group, 30 cases in each one. Both groups received conventional rehabilitation training. In the observation group, jingjin needling was applied at tendon blockage points of the shoulder, elbow, wrist, hip, knee, and ankle. In the control group, conventional acupuncture was applied at Jianyu (LI15), Quchi (LI11), Hegu (LI4), Biguan (ST31), Fengshi (GB31), Taichong (LR3), etc. on the affected side. Treatment was given once daily, 5 days a week for 4 weeks in both groups. The scores of clinical spasticity index (CSI), modified Ashworth scale, modified Barthel index (MBI), and Fugl-Meyer assessment scale (FMA) were evaluated before and after treatment, and the onset time was compared between the two groups. RESULTS: After treatment, the scores of CSI and modified Ashworth scale were decreased compared with those before treatment (P<0.001), while the scores of MBI and FMA were increased compared with those before treatment (P<0.001) in the two groups. After treatment, the scores of CSI and modified Ashworth scale in the observation group were lower than those in the control group (P<0.05), the MBI score in the observation group was higher than that in the control group (P<0.05). There was no statistically significant difference in FMA scores between the two groups (P>0.05). The onset time of the observation group was earlier than that in the control group (P<0.05). CONCLUSION Both jingjin needling combined with rehabilitation training and conventional acupuncture combined with rehabilitation training can effectively treat post-stroke spastic paralysis, jingjin needling combined with rehabilitation training exhibits better therapeutic effect and rapider onset.

BACKGROUND: Inflammation plays a critical role in severe cerebral venous thrombosis (CVT) pathogenesis, but the benefits of anti-inflammatory therapies remain unclear. This study aimed to investigate the association between steroid therapy combined with anticoagulation and the prognosis of acute/subacute severe CVT patients. METHODS: A prospective cohort study enrolled patients with acute/subacute severe CVT at Xuanwu Hospital (July 2020-January 2024). Patients were allocated into steroid and non-steroid groups based on the treatment they received. Functional outcomes (modified Rankin scale [mRS]) were evaluated at admission, discharge, and 6 months after discharge. Serum high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), cerebrospinal fluid (CSF) IL-6, and intracranial pressure were measured at admission and discharge in the steroid group. Fundoscopic Frisén grades were assessed at admission and 6 months after discharge. Univariate and multivariate logistic regression were used to evaluat associations between steroid use and favorable outcomes (mRS ≤2) at the 6-month follow-up. Paired tests assessed changes in hs-CRP and other variables before and after treatment, and Spearman's correlations were used to analyze relationships between these changes and functional improvements. RESULTS: A total of 107 and 58 patients in the steroid and non-steroid groups, respectively, were included in the analysis. Compared with the non-steroid group, the steroid group had a higher likelihood of achieving an mRS score of 0-2 (93.5% vs . 82.5%, odds ratio [OR] = 2.98, P  = 0.037) at the 6-month follow-up. After adjusting for confounding factors, the result remained consistent. Pulsed steroid therapy did not increase mortality during hospitalization or follow-up, nor did it lead to severe steroid-related complications (all P  >0.05). Patients in the steroid group showed a significant reduction in serum hs-CRP, IL-6, CSF IL-6, and intracranial pressure at discharge compared to at admission, as well as a significant reduction in the fundoscopic Frisén grade at the 6-month follow-up compare to at admission (all P  <0.001). A reduction in serum inflammatory marker levels during hospitalization positively correlated with improvements in functional outcomes ( P  <0.05). CONCLUSION: Short-term steroid use may be an effective and safe adjuvant therapy for acute/subacute severe CVT when used alongside standard anticoagulant treatments, which are likely due to suppression of the inflammatory response. However, these findings require further validation in randomized controlled trials. TRAIL REGISTRATION ClinicalTrials.gov , NCT05990894.

Objective : To analyze the differential expression profile of miRNAs in amniotic fluid exosomes of fetu- ses with Down syndrome (DS) and provide insights for identifying novel biomarkers for the prenatal diagnosis of DS . Methods : Amniotic fluid samples were collected from fetuses with DS and chromosomally normal fetuses . Exo- somes were isolated from the amniotic fluid and subjected to high-throughput sequencing. Differentially expressed miRNAs were identified , and target genes were predicted using TargetScan and miRanda. Target genes located on chromosome 21 were selected , and their biological functions and associated diseases were analyzed using Gene- Cards , HGNC , NCBI Gene , UniProtKB/Swiss-Prot , Ensembl , and OMIM databases . GO and KEGG enrichment analyses were performed to investigate the biological functions of the enriched genes . Results : A total of 59 differ- entially expressed miRNAs were identified , including 31 upregulated and 28 downregulated miRNAs . Based on a fold change > 2 and P < 0. 05 , 10 upregulated and 9 downregulated miRNAs with the highest expression levels were selected . Key miRNAs included hsa-let-7b-5p , hsa-let-7c-5p , hsa-let-7b-3p _ 1ss22CT , and hsa-miR-199b-5p , with BACH1 and IFNAR1 identified as their shared target genes . GO analysis revealed that the enriched target genes were primarily involved in protein binding , metal ion binding , transferase activity , DNA binding , transcriptional regulation by RNA polymerase Ⅱ , and nucleotide binding. KEGG pathway analysis indicated that the target genes were mainly associated with metabolic pathways , cancer-related pathways , the PI3K-Akt signaling pathway , and the Rap1 signaling pathway . Conclusion Differential expression of miRNAs in amniotic fluid exosomes was ob- served between DS fetuses and those with normal karyotypes . Combined analysis with placental miRNAs revealed hsa-miR-199b-5p as a common differentially expressed miRNA in both DS amniotic fluid and placenta. It is hypoth- esized that BACH1 and IFNAR1 , shared target genes of hsa-miR-199b-5p , hsa-let-7b-5p , hsa-let-7c-5p , and hsa- let-7b-3p_1ss22CT , may play a role in the pathogenesis of DS .

Background::Intrauterine growth restriction (IUGR) is associated with adverse metabolic outcomes during adulthood. Histone modifications and changes in DNA methylation-affected genes are important for fetal development. This study aimed to investigate the epigenetic mechanisms in IUGR.Methods::IUGR models were established in Sprague–Dawley rats using a maternal nutritional restriction approach during pregnancy. The abundance of insulin-like growth factor 2 (IGF2), phosphoinositide 3-kinase (PI3K), AKT serine/threonine kinase 2 (AKT2), and peroxisome proliferators-activated receptor gamma coactivator 1 alpha (PGC-1α) was examined by real-time polymerase chain reaction (RT-PCR) and Western blotting analysis. Chromatin immunoprecipitation RT-PCR was employed to analyze histone modification in CCCTC-binding factor (CTCF) 1–4 binding sites of the Igf2/H19 imprinting control region (ICR). The methylation states of CTCF1–4 binding sites were studied by pyrosequencing. Results::The IUGR models were constructed successfully. Igf2 mRNA abundance in the placenta, fetal liver, and newborn liver was decreased in the IUGR group ( P <0.01). Meanwhile, as compared with the control group, the expression levels of AKT2, PI3K, and PGC-1α were lower in newborn and 8-week-old livers in the IUGR group ( P <0.05). In addition, knocking down Igf2 reduced the protein expression levels of AKT2-phosphorylation and PGC-1α ( P <0.05). In CTCF binding sites 1-4 of the Igf2/ H19 ICR, acetylated histones H3 (AcH3) enrichment was significantly lower in CTCF1-3 in newborn and 8-week-old IUGR rats. Histone H3 tri-methylated lysine 4 (H3K4me3) enrichment was significantly lower in the CTCF1–4 of newborn and 8-week-old IUGR groups ( P <0.01). H3K9me2 enrichment was significantly higher in the IUGR group ( P <0.01). The CpG dinucleotide methylation levels of CTCF1 and CTCF3, but not those of CTCF2 and CTCF4 binding sites in IUGR rat fetal, 4-week old, and 8-week-old livers decreased significantly ( P <0.05). Conclusion::The methylation status and histone modification in the Igf2/H19 ICR are related to growth and lipid metabolism via the PGC-1α/PI3K/AKT2 pathway in IUGR rats.
