OBJECTIVES: To investigate the underlying causes and clinical manifestations in infants undergoing colonoscopy, and to analyze changes in disease spectrum. METHODS: Clinical data from 180 infants who underwent a total of 184 colonoscopies at the Department of Gastroenterology, Children's Hospital Affiliated to Shandong University from January 2015 to December 2024 were retrospectively analyzed. Patients were grouped by age: ≤6 months (n=41) and >6-12 months (n=139); and by examination period: 2015-2019 (n=83) and 2020-2024 (n=97). Primary causes for performing colonoscopy, final diagnoses, and disease spectrum evolution were assessed. RESULTS: Among 184 colonoscopies, the leading causes prompting examination were hematochezia (37.8%, 68/180), diarrhea (36.7%, 66/180), and co-occurring hematochezia and diarrhea (21.1%, 38/180). Causes for performing colonoscopy differed significantly by age group (P<0.05). Colonic polyps were only detected in the >6-12 months group (P<0.05). Compared to the 2015-2019 group, the 2020-2024 group had fewer food allergy-related gastrointestinal diseases (P<0.05) but more colitis (P<0.05). CONCLUSIONS Colonoscopy is essential for diagnosing infantile digestive disorders, with disease spectra varying by age and time period.

OBJECTIVE: To analyze the efficacy and safety of decitabine-based myeloablative preconditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with acute myeloid leukemia (AML). METHODS: The clinical characteristics and efficacy of 115 AML patients who underwent allo-HSCT at the First Medical Center of Chinese PLA General Hospital from August 2018 to August 2022 were retrospectively analyzed, including 37 patients treated with decitabine conditioning regimen (decitabine group) and 78 patients without decitabine conditioning regimen (non-decitabine group). The cumulative incidence of relapse (CIR), overall survival (OS), leukemia-free survival (LFS), non-relapse mortality (NRM) and graft versus host disease (GVHD) were analyzed. RESULTS: For the patients in first complete remission (CR1) state before allo-HSCT, the 1-year relapse rates of decitabine group(22 cases) and non-decitabine group(69 cases) were 9.1% and 29.6%, respectively, the difference was statistically significant(P =0.042). The 1-year cumulative incidence of acute graft-versus-host disease (aGVHD) in decitabine group and non-decitabine group was 62.2% and 70.5%, respectively, and the 1-year cumulative incidence of chronic inhibitor-versus-host disease (cGVHD) was 18.9% and 14.1%, respectively, there were no significant differences in the incidence of aGVHD and cGVHD between the two groups (P >0.05). Of the 115 patients, there were no significantly differences in the 1-year CIR(21.7% vs 28.8%, P =0.866), NRM(10.9% vs 3.9%, P =0.203), OS(75.2% vs 83.8%, P =0.131) and LFS(74.6% vs 69.1%, P =0.912) between the decitabine group(37 cases) and the non-decitabine group(78 cases). CONCLUSION Decitabine-based conditioning regimen could reduce the relapse rate of AML CR1 patients with good safety.

Lingguizhugan Decoction (LGZG) demonstrates significant efficacy in treating various cardiovascular diseases clinically, yet its precise mechanism of action remains elusive. This study aimed to elucidate the potential mechanisms and effects of LGZG on isoproterenol (ISO) continuous stimulation-induced chronic heart failure (CHF) in mice, providing direct experimental evidence for further clinical applications. In vivo, continuous ISO infusion was administered to mice, and ventricular myocytes were utilized to explore LGZG?s potential mechanism of action on the ?1-adrenergic receptor (?1-AR)/Gs/G protein-coupled receptor kinases (GRKs)/?-arrestin signaling deflection system in the heart. The findings reveal that LGZG significantly reduced the messenger ribonucleic acid (mRNA) expression of hypertrophy-related biomarkers [atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP)] and improved cardiac remodeling and left ventricular diastolic function in mice with ISO-induced CHF. Furthermore, LGZG inhibited the overactivation of Gs/cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signaling and downregulated the downstream transcriptional activity of cAMP-response element binding protein (CREB) and the expression of the coactivator CBP/P300. Notably, LGZG downregulated the expression of ?-arrestin1 and GRK 2/3/5 while upregulating the expression of ?1-AR and ?-arrestin2. These results suggest that LGZG inhibits Gs/cAMP/PKA signaling and ?-arrestin/GRK-mediated desensitization and internalization of ?1-AR, potentially exerting cardioprotective effects through the synergistic regulation of the ?1-AR/Gs/GRKs/?-arrestin signaling deflection system via multiple pathways.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To explore the correlation of different HBV DNA loads with peripheral blood lymphocyte subsets and interleukin-6 (IL-6) in patients with chronic hepatitis B.Methods:A cross-sectional study was conducted. A total of 519 patients with chronic hepatitis B admitted to the Fifth Medical Center of the General Hospital of the People′s Liberation Army from April 2019 to June 2024 were included. The patients were divided into high, medium, and low viral load groups and a negative group based on HBV DNA load. Another 100 healthy individuals who underwent physical examinations during the same period were recruited as the control group. The quantities of peripheral blood lymphocyte subsets and IL-6 levels were compared among the groups. Meanwhile, alanine aminotransferase (ALT) levels were recorded and compared among the groups. The correlation of HBV DNA levels with lymphocyte subsets and IL-6 was analyzed using Pearson correlation analysis.Results:HBV DNA loads were negatively correlated with the counts of CD3 +, CD4 +, CD8 +, CD19 +, and CD56 + lymphocyte subsets (correlation coefficients r were -0.483, -0.508, -0.524, -0.573, and -0.561, respectively; all P<0.001) and positively correlated with IL-6 levels ( r=0.862, P<0.05). Compared with the control group, the counts of each lymphocyte subset were higher in the high, medium, and low viral load groups ( P<0.05). In the HBV DNA-negative chronic hepatitis B group, the counts of CD8 + and CD19 + lymphocyte subsets were significantly higher [712.32(526.00,898.64) and 495.62(345.74,645.50) cells/μl] than those in the control group [612.10(479.89,744.31) and 470.32 (396.00,544.64) cells/μl] ( P<0.05). Conclusion:The degree of HBV replication activity in patients with chronic hepatitis B is associated with the immune status of the body, and negatively correlated with the quantities of lymphocyte subsets and positively correlated with IL-6 levels.

Objective To analyze the academic literature on sepsis-related microRNA(miRNA)at worldwide,and to dentify thematic hotspots and future research trends.Methods A bibliometric analysis was employed to retrieve the literature on sepsis-related miRNA published in the core collection of China National Knowledge Infrastructure(CNKI),and Web of Science(WOS)databases from January 1,2010,to January 1,2025,which met the article inclusion criteria,and used CiteSpace 6.3.1 software to perform the co-occurrence analysis of keywords,keyword emergence analysis,and cluster analysison;on the basis of these analyses,the keywords were sorted according to time to generate clustering time line figure to explore the current status and hotspot evolution process of sepsis-related miRNA.Results A total of 135 and 1 278 articles were retrieved from CNKI and the core collection of WOS databases,respectively.The frequency and centrality of keywords such as sepsis,prognosis,microRNA,acute lung injury,acute kidney injury,etc.were high in 135 documents in CNKI;in 1 278 documents in WOS core collection,the frequency and centrality of keywords such as expression,sepsis,inflammation,cells,micrornas,etc.were high;The top 10 keywords in the CNKI database in terms of burst intensity were:microRNA,inflammatory response,inflammatory factor,interleukin-10,tumor necrosis factor-α,acute respiratory distress syndrome,interleukin-35,septic shock,rat,tiny microRNA-155(miR-155);the top 10 keywords in the core collection of the WOS database in terms of burst intensity were:expression,NF-κB,microRNA,cells,induction,pathway,mechanisms,septic shock,mortality,cancer.Representative clustering tags in the CNKI are#0 prognosis,#1 miRNA,#2 septic shock;The representative clustering labels in the core collection of WOS database are#0 acute lung injury,#1 cancer,#2 septic shock,and so on.In CNKI and WOS core databases,the early keywords mainly revolve around the study of inflammatory factors and related mechanisms of sepsis,and the research center gradually shifts to the clinical physiological injuries as well as complications and mortality in the later stage,miRNA-126,AMP-activated protein kinase,interleukin-35 and other keywords have emerged.Among the top 10 most-cited English literature,researchers have paid particular attention to studying various miRNA as potential biomarkers of sepsis,including miR-146a,miR-223 and miR-146.Conclusions There are similarities and differences in the direction and hotspots of sepsis-related miRNA research in China and abroad.The research paradigm of sepsis has gradually shifted from the early clinical observation focusing on the overall complications and prognosis of patients to the basic research centered on the molecular mechanisms of inflammatory factors and signaling pathways.In this context,the study of miRNA as novel biomarkers for sepsis has been increasingly emphasized,and miRNA represent a promising direction for sepsis research,with potential applications both in basic research and clinical treatment.

Objective:To explore the influencing factors of dietary habits on the progression from prediabetes to type 2 diabetes mellitus(T2DM)in elderly individuals undergoing health check-ups.Methods:In the cross-sectional study, we enrolled individuals aged 60-70 years with fasting plasma glucose (FPG)≥6.0 mmol/L who underwent health examinations at the Health Management Medical Center of Wenjiang District People's Hospital in Chengdu from 2019 to 2022.Demographic characteristics, dietary habit questionnaires, and FPG values were collected.Unconditional binary logistic regression analysis was used to identify factors influencing the natural progression from prediabetes to T2DM.A nomogram prediction model was established based on logistic regression results, and its predictive performance was evaluated by calculating the C-statistics and drawing a calibration curve.Results:A total of 13 681 elderly participants with FPG ≥6.0 mmol/L were included, comprising 4 306(31.5%)prediabetes cases(FPG 6.0-7.0 mmol/L), aged(63.54±16.49)years and 9 375(68.5%)T2DM cases(FPG>7.0 mmol/L), aged(63.09±16.21)years.Unconditional binary logistic regression analysis showed that frequent breakfast( OR=0.777, 95% CI: 0.696-0.868, P<0.001), dietary preference for light diet( OR=0.781, 95% CI: 0.710-0.858, P<0.001), salty taste( OR=0.571, 95% CI: 0.504-0.648, P<0.001), raw food( OR=0.327, 95% CI: 0.224-0.478, P<0.001)and spicy taste( OR=0.124, 95% CI: 0.112-0.137, P<0.001)were the protective factors for the conversion of prediabetes to the T2DM stage in the elderly physical examination population.While fast eating rate( OR=4.327, 95% CI: 3.978-4.772, P<0.001), dietary preference for sweets( OR=5.168, 95% CI: 4.703-5.678, P<0.001), and high-fat diet( OR=1.401, 95% CI: 1.275-1.539, P<0.001)were risk factors for conversion of prediabetes to T2DM stage.C-statistic of the Nomogram prediction model was 0.781; the goodness-of-fit test of the calibration curve was χ2=11.258, P=0.188, and the model predicted well. Conclusions:Regular breakfast, light diet, and dietary preferences for salty, raw, and spicy foods were protective factors for the transition from prediabetes to T2DM stage, whereas rapid eating rate, preference for sweets, and high-fat diets were risk factors for the transition from prediabetes to T2DM stage in the medical examination population.The constructed risk prediction model helped to find out the magnitude of the risk of T2DM in an individual, which increases the evidence for the transition from prediabetes to T2DM stage prevention evidence.

Objective: To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom. Methods: From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted. Results: The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05). Conclusions Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

This study investigated the effect of Wuling San on transforming growth factor-β1(TGF-β1)-induced fibrosis, inflammation, and oxidative stress in human renal tubular epithelial cells(HK-2) and its mechanism of antioxidant stress injury. HK-2 cells were cultured in vitro and divided into a control group, a TGF-β1 model group, and three treatment groups receiving Wuling San-containing serum at low(2.5%), medium(5.0%), and high(10.0%) doses. TGF-β1 was used to establish the model in all groups except the control group. CCK-8 was used to analyze the effect of different concentrations of Wuling San on the activity of HK-2 cells with or without TGF-β1 stimulation. The expression of key fibrosis molecules, including actin alpha 2(Acta2), collagen type Ⅰ alpha 1 chain(Col1α1), collagen type Ⅲ alpha 1 chain(Col3α1), TIMP metallopeptidase inhibitor 1(Timp1), and fibronectin 1(Fn1), was detected using qPCR. The expression levels of inflammatory cytokines, including tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6(IL-6), interleukin-8(IL-8), and interleukin-4(IL-4), were measured using ELISA kits. Glutathione peroxidase(GSH-Px), malondialdehyde(MDA), catalase(CAT), and superoxide dismutase(SOD) biochemical kits were used to analyze the effect of Wuling San on TGF-β1-induced oxidative stress injury in HK-2 cells, and the expression of nuclear factor E2-related factor 2(Nrf2), heme oxygenase 1(HO-1), and NAD(P)H quinone oxidoreductase 1(NQO1) was analyzed by qPCR and immunofluorescence. The CCK-8 results indicated that the optimal administration concentrations of Wuling San were 2.5%, 5.0%, and 10.0%. Compared with the control group, the TGF-β1 model group showed significantly increased levels of key fibrosis molecules(Acta2, Col1α1, Col3α1, Timp1, and Fn1) and inflammatory cytokines(TNF-α, IL-1β, IL-6, IL-8, and IL-4). In contrast, the Wuling San administration groups were able to dose-dependently inhibit the expression levels of key fibrosis molecules and inflammatory cytokines compared with the TGF-β1 model group. Wuling San significantly increased the activities of GSH-Px, CAT, and SOD enzymes in TGF-β1-stimulated HK-2 cells and significantly inhibited the level of MDA. Furthermore, compared with the control group, the TGF-β1 model group exhibited a significant reduction in the expression of Nrf2, HO-1, and NQO1 genes and proteins. After Wuling San intervention, the expression of Nrf2, HO-1, and NQO1 genes and proteins was significantly increased. Correlation analysis showed that antioxidant stress enzymes(GSH-Px, CAT, and SOD) and Nrf2 signaling were significantly negatively correlated with key fibrosis molecules and inflammatory cytokines in the TGF-β1-stimulated HK-2 cell model. In conclusion, Wuling San can inhibit TGF-β1-induced fibrosis in HK-2 cells by activating the Nrf2 signaling pathway, improving oxidative stress injury, and reducing inflammation.
