ObjectiveTo investigate the potential mechanism of Shenqi Yiliu Formula （参芪抑瘤方） in treating precancerous lesions of gastric cancer （PLGC） by the Wnt/β-catenin signaling pathway. MethodsThe CCK-8 assay was used to determine the optimal intervention time for Shenqi Yiliu Formula drug-containing serum and the concentration of the Wnt/β-catenin pathway inhibitor XAV939 depends on the survival rate of AGS gastric cancer cell line. AGS cells were divided into the gastric cancer cell group （15% blank serum）， inhibitor group （selected concentration of XAV939）， high-dose Shenqi Yiliu Formula group （12% Shenqi Yiliu Formula drug-containing serum + 3% blank serum）， medium-dose Shenqi Yiliu Formula group （6% Shenqi Yiliu Formula drug-containing serum + 9% blank serum）， and low-dose Shenqi Yiliu Formula group （3% Shenqi Yiliu Formula drug-containing serum + 12% blank serum）. Each group was tested in triplicate. After culturing for 24 and 48 hours， cell migration and invasion were assessed by scratch assays； after a selected intervention period （48 hours）， cell cycle distribution was analyzed using flow cytometry， Ki67 protein levels were detected by immunofluorescence， the protein levels of Wnt， β-catenin， GSK-3β， and intranuclear T-cell specific factor（TCF） were measured by the protein immunoblotting assay， and the mRNA expressions of these above factors were determined by quantitative real-time PCR. ResultsThe optimal intervention time for Shenqi Yiliu Formula drug-containing serum was determined to be 48 hours， and the effective concentration of XAV939 was 20 μmol/L. Compared with the gastric cancer cell group， Shenqi Yiliu Formula at all doses reduced the cell migration rate at 24 and 48 hours （P＜0.05）， except for the low-dose group at 24 hours. Compared to the low-dose group at corresponding time points， high- and medium-dose Shenqi Yiliu Formula groups showed significantly reduced migration rates， particularly the high-dose group at 48 hours （P＜0.05）. Compared with the gastric cancer cell group， the high-dose Shenqi Yiliu Formula and inhibitor groups exhibited reduced protein and mRNA levels of Wnt， β-catenin， and TCF， along with reduced Ki67 protein levels and a decreased proportion of cells in the S and G2 phases of the cell cycle， but GSK-3β protein levels， GSK-3β mRNA expression， and the proportion of cells in the G1 phase increased （P＜0.05）. Compared to the inhibitor group， the high-dose Shenqi Yiliu Formula group showed a decreased proportion of G1-phase cells and an increased proportion of G2-phase cells （P＜0.05）， although differences in Wnt and β-catenin protein levels and mRNA expressions were not statistically significant （P＞0.05）. ConclusionShenqi Yiliu Formula drug-containing serum inhibits the migration and invasion of gastric cancer AGS cells and block the cell cycle at G1 phase， and its underlying mechanism may be related to the regulation of the Wnt/β-catenin signaling pathway.

Objective To explore the trend of lung cancer prevalence and influencing factors in a Hospital of Zigong from 2019-2023. Methods Select 2 835 lung cancer patients in Zigong region admitted to the Zigong Fourth People's Hospital from January 2019 to December 2023, and analyze the changes in the clinical characteristics and age strata of patients in different time periods in this group. Three thousand non-cancer respiratory patients in the same time period were included to compare the differences in patient data and to analyze the influencing factors affecting the changes in the characteristics of lung cancer in this region. Results There was an upward trend in the number of patients with pneumonia included between 2019 and 2023, with the highest volume of patients included in 2021 (609 cases). Over the 5-year period, the percentage of patients aged 0-39 years did not change significantly and accounted for a relatively low percentage. The proportion of patients aged 40-49 years increased (APC=0.69%, t=2.990, P<0.05), and the proportion of patients over 60 years old decreased, but to a lesser extent (APC=-0.25%, t=2.210, P<0.05). There were no significant differences in male percentage, lesion site, distant metastasis, smoking history and tumor diameter among patients in different years (all P>0.05). There were significant differences in TNM stage and lymphatic metastasis among patients in different years (all P<0.05). Compared with 2019, the proportion of early stage and patients with lymph node metastasis showed an upward trend within five years (χ²_{early stage}=9.153, P_{early stage}=0.002; χ²_{lymph node metastasis}=5.848, P_{lymph node metastasis}=0.016). The factor associated with the change in age of lung cancer patients in different years was family history of lung cancer (P<0.01). Factors associated with histologic changes in lung cancer patients in different years were age, family history of lung cancer and smoking history (all P<0.05). Factors associated with changes in TNM distribution in lung cancer patients in different years were age, tumor diameter, family history of lung cancer and lymph node metastasis (all P<0.05). Factors associated with changes in lymph node metastasis in lung cancer patients in different years were tumor diameter and TNM stage (all P<0.05). Conclusion From 2019 to 2023, the age of patients with lung cancer in a Hospital in Zigong area showed a decreasing trend, which may be influenced by family history of lung cancer.Patients with TNM early stage and lymph node metastasis increased respectively, which influenced each other and were interfered by factors of age, tumor diameter, and family history of lung cancer.

Cardiac fibrosis is characterized by an elevated amount of extracellular matrix (ECM) within the heart. However, the persistence of cardiac fibrosis ultimately diminishes contractility and precipitates cardiac dysfunction. Circular RNAs (circRNAs) are emerging as important regulators of cardiac fibrosis. Here, we elucidate the functional role of a specific circular RNA CELF1 in cardiac fibrosis and delineate a novel feedback loop mechanism. Functionally, circ-CELF1 was involved in enhancing fibrosis-related markers' expression and promoting the proliferation of cardiac fibroblasts (CFs), thereby exacerbating cardiac fibrosis. Mechanistically, circ-CELF1 reduced the ubiquitination-degradation rate of BRPF3, leading to an elevation of BRPF3 protein levels. Additionally, BRPF3 acted as a modular scaffold for the recruitment of histone acetyltransferase KAT7 to facilitate the induction of H3K14 acetylation within the promoters of the Celf1 gene. Thus, the transcription of Celf1 was dramatically activated, thereby inhibiting the subsequent response of their downstream target gene Smad7 expression to promote cardiac fibrosis. Moreover, Celf1 further promoted Celf1 pre-mRNA transcription and back-splicing, thereby establishing a feedback loop for circ-CELF1 production. Consequently, a novel feedback loop involving CELF1/circ-CELF1/BRPF3/KAT7 was established, suggesting that circ-CELF1 may serve as a potential novel therapeutic target for cardiac fibrosis.

ObjectiveTo investigate and explore the characteristics and influencing factors of glucose metabolism in children with β-thalassemia major （β-TM） after allogeneic hematopoietic stem cell transplantation （allo-HSCT）. MethodsThe follow-up data of 41 patients with β-TM who underwent HSCT at Hematopoietic Stem Cell Transplantation Department of Children's Medical Center of Sun Yat-sen Memorial Hospital， Sun Yat-sen University were retrospectively analyzed. Their glucose metabolism characteristics were evaluated through laboratory tests and the related influencing factors were analyzed. ResultsIn the study， 41.46% （17/41） of patients developed abnormal glucose homeostasis after HSCT. Among them， 82.35% （14/17） characterized by insulin resistance， but no cases of diabetes mellitus were found. The results of insulin releasing test and oral glucose tolerance test（OGTT） showed that 45.00% （9/20） of patients had abnormal insulin releasing curve and 40.0% （8/20） had delayed serum glucose peak. The average age of HSCT in abnormal glucose homeostasis group was significantly older than that in the normal glucose homeostasis group ［（8.8±3.9） years old vs （6.0±3.1） years old， P=0.015］. ConclusionsPatients with β-TM after HSCT may develop abnormal glucose homeostasis， consists largely of insulin resistance. The elder age of HSCT （≥7 years old） is a risk factor for abnormal glucose homeostasis in β-TM patients after HSCT. It is recommended to regularly monitor glucose metabolism indicators in β-TM children after HSCT， especially in elderly transplant recipients.

The theory of "yang transforming qi and yin shaping up body" comes from Huangdi Neijing (Inner Canon of Yellow Emperor),which describes the basic form of human metabolism dominated by "yang transforming qi":the effect of " yang transforming qi" leads the energy metabolism of human body,while the effect of "yin shaping up body" leads the material metabolism. Metabolic syndrome is a clinical syndrome with metabolic disorders of protein,fat and carbohydrate. The theory of "yang transforming qi and yin shaping up body" has a strong guiding value for the pathogenesis analysis and clinical differentiation and treatment of metabolic syndrome. Yin and yang represent the two basic trends of the change and development of things,and the functions of "transforming qi" and "shaping up body" are the main manifestations of them in metabolism. From this perspective,this paper suggests that the key pathogenesis of metabolic syndrome should be "insufficiency of yang transforming qi and impairment of yin shaping up body" based on the mutual assistance of yin and yang. On this basis we take "coordinating yin-yang and promoting the reproduction of them" as the main directions of therapy,which provides a new idea for the treatment of metabolic syndrome.

Objective To explore the prognostic impact and clinical application value of therapeutic plasma exchange(TPE)intervention timing and liver injury periodization in patients with exertional heat stroke(EHS).Methods Data of 127 EHS patients from the First Medical Center of the General Hospital of the People′s Liberation Army from January 2011 to December 2023 were collected,then divided into the death group and the survival group based on therapeutic outcomes and into 5 stages according to the dynamic changes of ALT,AST,TBIL and DBIL.According to propensity score matching analysis,11 patients in the survival group and 12 patients in the death group were included in the statistical analysis,and 20 of them were treated with TPE.The changes in indicators and clinical outcomes before and after TPE were observed,in order to evaluate the impact of intervention timing on prognosis.Results Among the 23 patients,14 had no liver injury or could progress to the repair phase,resulting in 3 deaths(with the mortality rate of 21.43%),while 9 patients failed to pro-gress to the repair phase,resulting in 9 deaths(with the mortality rate of 100%),with significant differences(P＜0.05).The mortality rate of the first TPE intervention before the third stage of liver injury was 23.08%(3/13),while that of interven-tion after reaching or exceeding the third stage was 85.71%(6/7),and the difference was statistically significant(P＜0.05).Conclusion TPE should be executed actively in EHS patients combined with liver injury before the third phase to lock its pathological and physiological processes,thereby improving prognosis and reducing mortality.

Objective:To analyze the detection of colorectal advanced neoplasms in the population who underwent colonoscopy screening in Henan Province as part of the Urban China Cancer Screening Program and its influencing factors.Methods:A cross-sectional study design was employed. Based on the Cancer Screening Program conducted in Henan Province, the study enrolled 7 454 urban residents who manifested no symptoms and were recruited from eight cities in the province, including Zhengzhou, Zhumadian, Anyang, Luoyang, Nanyang, Jiaozuo, Xinxiang, and Puyang from October 2013 to October 2019, and participated in colonoscopy screening. The χ 2 test was used to compare the detection rates of colorectal advanced neoplasms among participants with different characteristics, and a multivariate logistic stepwise regression model was used to analyze the factors affecting the detection rates. Results:A total of 7 454 subjects underwent colonoscopy screening, and 112 cases of colorectal advanced neoplasms were detected. Multivariate logistic regression analysis suggested that older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative were risk factors for colorectal advanced neoplasms. The detection rate was significantly higher in people aged 60-74 years compared with those aged 40-49 years, with an odds ratio ( OR) of 2.04 (95% CI: 1.23-3.38).The rates were higher in people who smoked than those who did not smoke, with an OR of 2.21 (95% CI: 1.48-3.31), and in people who consumed more meat than those who consumed less, with an OR of 1.53 (95% CI: 1.04-2.26). Those with diabetes had a higher detection rate compared with those without, with an OR of 1.69 (95% CI: 1.07-2.69), and those with a first-degree family history of colorectal cancer had a higher detection rate than those without, with an OR of 1.64 (95% CI: 1.09-2.46). Conclusion:The detection rate of colorectal advanced neoplasms through colonoscopy screening in Henan Province covered by the Urban China Cancer Screening Program is 1.50%. Older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative are identified as risk factors for colorectal advanced neoplasms.

Objective:To analyze the 5-year relative survival rate of cancer in Henan province based on cancer registration data.Methods:Cancer survival data were extracted from the cancer registration database of Henan province with the diagnosis date between January 1, 2010 and December 31, 2019 were included. The closing date of follow-up was set as December 31, 2019. The 5-year relative survival rate of cancer was calculated using the period survival analysis method and the Ederer II method in the R package "periodR", and the interest period was between 2015 and 2019.Results:During the period of 2015-2019, the overall 5-year relative survival rate of cancer patients in Henan province was 43.6%, and after age-standardization, it was 40.2%. The overall 5-year relative survival rate showed the characteristics of higher survival rate in females than males (45.9% vs 34.7%, Z=39.60, P＜0.001) and higher survival rate in urban areas than rural areas (44.9% vs 39.1%, Z=12.97, P＜0.001). The 5-year relative survival rate for cancer patients among children aged 0-14 was 60.2%, and for adults aged 15 and above, it was 43.5%, which was standardized to 40.2% after age adjustment. There are two types of cancers with a standardized 5-year relative survival rate exceeding 70% (thyroid cancer at 82.2% and breast cancer at 71.6%), and four cancers with a rate below 30% (pancreatic cancer at 18.2%, liver cancer at 19.6%, lung cancer at 24.0%, and gallbladder cancer at 26.6%). Conclusion:The cancer 5-year survival rate in Henan Province is lower than that of the national average, indicating the need for continued enhancement of cancer prevention and control measures.

ObjectiveTo explore the clinical features and causative genes of short stature children with unknown etiology， providing evidence for precise clinical diagnosis and treatment. MethodsThe study recruited children with suspected but undiagnosed short stature from the pediatric endocrinology department in our hospital between January 2018 and August 2022. A retrospective analysis was performed on the clinical manifestations， laboratory test and whole exome sequencing （WES） results. Causative genes were classified and analyzed according to different pathogenic mechanisms. ResultsA total of 48 children （30 boys and 18 girls） were enrolled， aged 7.73 ± 3.97 years， with a height standard deviation score （ HtSDS） of -3.63 ± 1.67. Of the patients， 33 （68.8%） suffered from facial anomalies， 31 （64.6%） from skeletal abnormalities， 26 ［54.2%， 61.5% of whom born small for gestational age （SGA）］ from perinatal abnormalities， 24 ［50.0%， 87.5% of whom with growth hormone （GH） peak concentration below normal］ from endocrine disorders and 21（43.8%） had a family history of short stature. Laboratory tests showed that GH peak concentration following stimulation test was （9.72 ± 7.25） ng/mL， IGF-1 standard deviation score was -0.82 ± 1.42， the difference between bone age and chronological age was -0.93 ± 1.39 years. Of the 25 cases with mutant genes found by WES， 14 （56.0%） had pathogenic mutation， 6 （24.0%） likely pathogenic mutation， and 5 （20.0%） mutation of uncertain significance. Pathogenic and likely pathogenic variants were identified in 14 genes， including 10 affecting intracellular signaling pathways （PTPN11， RAF1， RIT1， ARID1B， ANKRD11， CSNK2A1， SRCAP， CUL7， SMAD4 and FAM111A） and 4 affecting extracellular matrix （ECM） components or functions （ACAN， FBN1， COL10A1 and COMP）. ConclusionsA rare monogenic disease should be considered as the possible etiology for children with severe short stature accompanied by facial anomalies， disproportionate body types， skeletal abnormalities， SGA， GH peak concentration below normal and a family history of short stature. WES played an important role in identifying the monogenic causes of short stature. This study indicated that affecting growth plate cartilage formation through intracellular signaling pathways and ECM components or functions was the main mechanism of causative genes leading to severe short stature in children. Further research may help discover and study new pathogenic variants and gene functions.

Objective:To detect the changes in the biological activity and expression of long-chain non-coding RNA-p21 (lncRNA-p21) in human lens epithelial cells HLE-B3 damage induced by hydrogen peroxide.Methods:HLE-B3 cells were divided into normal control group and hydrogen peroxide group, which were cultured in normal culture medium and culture medium containing 200 μmol/L hydrogen peroxide for 24 hours, respectively.Cell viability was determined by MTS colorimetric method.Cellular reactive oxygen species (ROS) level was detected using ROS assay kits.Cell apoptosis was tested by flow cytometry.Cell Caspase-3 activity was detected using Caspase-3 assay kit.Expressions of Bax and Bcl-2 proteins related to cell apoptosis were determined by Western Blot.Cell cycle distribution was determined by flow cytometry.Cell proliferation ability was detected by EDU proliferation assay kit.The expression of lncRNA-p21 in cells was detected by real time fluorescence quantitative polymerase chain reaction (PCR).The localization of lncRNA-p21 in cells was detected by fluorescence in situ hybridization.Results:The ROS content of cells in hydrogen peroxide group was (4.65±0.38), significantly higher than (1.00±0.01) of normal control group, and the difference was statistically significant ( t=16.66, P<0.05).Compared with the normal control group, the cell apoptosis rate was significantly increased, the activity of Caspase-3 was enhanced, and the relative expression of Bax was significantly increased in the hydrogen peroxide group, with statistically significant differences ( t=20.69, 39.80, 12.73, all at P<0.05).Compared with the normal control group, the proportion of G2 phase cells in the hydrogen peroxide group significantly increased, showing a statistically significant difference ( t=23.10, P<0.05).The EDU-positive cell rate of hydrogen peroxide group was (25.41±6.99)%, significantly lower than (50.58±9.15)% of normal control group ( t=6.559, P<0.05).The relative expression level of lncRNA-p21 in the hydrogen peroxide group was 2.36±0.29, significantly higher than 1.02±0.02 in the normal control group ( t=7.893, P<0.05).The fluorescence in situ hybridization experiments indicate that lncRNA-p21 was localized in the cytoplasm. Conclusions:In the oxidative stress model induced by hydrogen peroxide, the proliferation ability of lens epithelial cells significantly decreases, the apoptosis level significantly increases, and the expression levels of ROS and lncRNA-p21 enhances.lncRNA-p21 may be involved in the oxidative stress injury process of lens epithelial cells.
