Gastric ulcer （GU） is a high-incidence digestive system disease characterized pathologically by disruption of gastric mucosal integrity， with clinical features including a prolonged course and periodic recurrence. Modern medicine attributes its pathogenesis to the dynamic imbalance between aggressive and defensive factors，while traditional Chinese medicine （TCM） posits its development as closely linked to spleen deficiency. Current therapies combining acid suppressants and antibiotics face challenges such as high recurrence rates，poor mucosal healing，and adverse drug reactions. Long-term use may induce metabolic disturbances like hypergastrinemia and reduced intestinal microbiota diversity. Therefore，exploring safer and longer-lasting therapeutic strategies has become a critical focus. TCM has extensive clinical experience and unique advantages in GU prevention and treatment. Studies demonstrate that the classic formula Shenling Baizhu San exhibits therapeutic properties of "invigorating spleen and tonifying Qi to restore physiological balance and eliminating dampness and regulating middle energizer to unblock Qi movement"， enabling a holistic approach targeting both symptoms and root causes in GU with spleen deficiency as the core pathology by suppressing aggressive factors and strengthening defensive factors. Experimental research reveals its mechanisms involve enhancing the physicochemical barrier of the mucus layer，repairing epithelial barriers and microcirculation，modulating gastric acid secretion and gastrointestinal motility，and regulating microecological barriers and mucosal immunity. Clinical evidence confirms its synergistic effects in promoting ulcer healing，improving Helicobacter pylori eradication rates，and reducing recurrence risks. This review examined the etiology and pathogenesis of GU and systematically evaluated Shenling Baizhu San from three perspectives-clinical application，pharmacological effects， and experimental research-to provide insights for optimizing integrated traditional Chinese and Western medicine protocols and expanding its clinical applications.

Objective:To investigate factors influencing frequent episodes (≥ 4 episodes within 1 year) in children with moderate-to-severe atopic dermatitis (AD) in China.Methods:A national multicenter cross-sectional study was conducted. Patients under the age of 18 years diagnosed with moderate-to-severe AD were enrolled at dermatology clinics in 18 medical institutions across 12 provinces and municipalities in China between June 12 and August 8, 2023. At the time of the visit, their guardians completed a structured questionnaire covering demographic characteristics, clinical features of AD, personal and family history, factors associated with frequent episodes of moderate-to-severe AD, compliance with treatment, and disease awareness. Statistical analyses included t tests, one-way analysis of variance, rank-sum tests, and chi-square tests, with multiple-response analysis applied for multiple-choice questions. Results:A total of 965 valid questionnaires were collected, and 965 children with moderate-to-severe AD were included. Among them, there were 531 males and 434 females, 678 (70.3%) were aged 2 - < 12 years, 837 (86.7%) were from urban areas, the age at onset was 2.47 ± 3.03 years, and the median frequency of AD episodes in the past year was 4 times. These children were divided into 2 groups based on the median episode frequency: < 4-episode group (439 cases, 45.5%) and ≥ 4-episode group (526 cases, 54.5%). Compared with the < 4-episode group, children in the ≥ 4-episode group showed younger ages at onset (2.22 ± 2.98 years vs. 2.76 ± 3.06 years, P = 0.006) and higher proportions of patients with comorbid allergic diseases in both the children themselves (82.9% [436/526] vs. 69.7% [306/439], χ2 = 23.42, P < 0.001) and their relatives (66.0% [347/526] vs. 57.4% [252/439], χ2 = 7.46, P = 0.006). Children in the ≥ 4- episode group also had higher monthly usage of moisturizers (150 [30, 300] g vs. 60 [6, 200] g) and daily frequency of moisturizer use, greater disease awareness, but more severe fear of medication use (all P < 0.05). The region and the human development index level were both significantly associated with the episode frequency (both P < 0.001), with the highest proportion of children from South China in the ≥ 4- episode group (36.3%, 191/526). Children in the ≥ 4-episode group also had a longer duration of topical glucocorticoid use than those in the < 4-episode group ( Z = -2.21, P = 0.027). External triggers associated with AD episodes mainly included heat exposure (50.36%, 486/965), hot water bathing (40.73%, 393/965), seafood (23.52%, 227/965), and dust mites (33.37%, 322/965) . Conclusion:In children with moderate-to-severe AD in China, factors influencing frequent episodes may include residence in southern or economically developed regions, earlier age at onset, having a personal or family history of allergic diseases, and fear of medication use.

Objective:To summarize the clinical characteristics of plaque psoriasis patients with thrombocytopenia, and to evaluate the efficacy and safety of biologics in such patients.Methods:A single-center retrospective cohort study was conducted. Clinical data were collected from plaque psoriasis patients with thrombocytopenia at the Department of Dermatology, Peking University Third Hospital between January 2017 and October 2024. Comparative analysis was conducted on clinical data, such as platelet counts, before and after the use of biologics, and the efficacy and safety of biologics were evaluated.Results:Eleven patients (10 males, 1 female; age range: 33 - 72 years) had thrombocytopenia prior to biologic therapy. Thrombocytopenia was caused by hypersplenism secondary to liver cirrhosis in 7 patients, and the causes of cirrhosis including prior medications for psoriasis (5 cases) and viral hepatitis (2 cases) ; 3 patients were diagnosed with primary immune thrombocytopenia (ITP), and 1 patient with aplastic anemia. All the 11 patients achieved a Psoriasis Area and Severity Index (PASI) 90 response after biologic therapy. Only one patient experienced a transient episode of further decrease in platelet counts, which was considered potentially related to anti-tuberculosis drugs. The Wilcoxon signed-rank test showed no significant decrease in platelet counts after biologic therapy in the 11 patients (pre-treatment platelet counts M [ Q1, Q3]: 77 [55, 87] × 10 9/L, post-treatment platelet counts: 84 [65, 114] × 10 9/L, P = 0.083) ; notably, 3 patients with ITP showed an upward trend in platelet counts after treatment with interleukin (IL) -17A or IL-23 inhibitors. Conclusions:Thrombocytopenia may not be a contraindication for biologic therapy in patients with plaque psoriasis. Plaque psoriasis patients with ITP may obtain dual benefits from the use of IL-17A inhibitors or IL-23 inhibitors.

Objective:To summarize the clinical characteristics of elderly patients with stage Ⅰ diffuse large B-cell lymphoma (DLBCL) and analyze the factors associated with prognosis.Methods:A case series study was conducted by retrospectively collecting clinical data from patients aged over 60 years with newly diagnosed stage Ⅰ DLBCL across 20 medical centers in Jiangsu Province, China, between June 2010 and April 2023. The involved site, classification and treatment plan were summarized. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Statistical analyses were performed using the Kaplan-Meier method, and Cox regression model.Results:The study included 255 patients with a median age of 69 years, of whom 130 (51.0%) were male, 66 (25.9%) were aged ≥75 years and 26 (10.1%) had a high Charlson Comorbidity Index (CCI) score of ≥2. Extranodal involvement was observed in 163 (63.9%) patients, with the stomach (37.4%, 61/163), intestine (19.0%, 31/163), testes (11.0%, 18/163), and breast (7.4%, 12/163) being the most frequently affected sites. The non-germinal center B-cell (non-GCB) subtype was prevalent in 63.7% of patients (142/223), with no significant difference between the nodal and extranodal groups ( P=0.681). Furthermore, 73.9% (184/249) and 11.7% (29/249) of patients received the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) and R-miniCHOP regimen, respectively. The overall 3-year PFS rate was 81.5%, and the 3-year OS rate was 85.6%. Patients aged ≥75 years ( HR=2.910, 95% CI 1.565-5.408, P=0.001) and/or with a CCI score ≥2 ( HR=2.324, 95% CI 1.141-4.732, P=0.020) had a significantly poorer PFS. Incorporating age ≥75 years and CCI score ≥2 into the stage-modified international prognostic index (sm-IPI) can better stratify the prognosis of elderly patients with stage Ⅰ DLBCL. The 3-year PFS rate was 48.7% in the high-risk group versus 85.7% in the low-risk group ( P<0.001). Conclusions:Our findings show that the elderly patients with stage Ⅰ DLBCL were predominantly characterized by extranodal involvement (particularly in the stomach and intestinal tract) and non-GCB subtype. Age ≥75 years and CCI ≥2 were identified as independent prognostic factors. The newly established sm-IPI-75-CCI incorporating these factors demonstrated superior prognostic discrimination compared to conventional risk assessment systems.

AIM To investigate the protective effects of verbascoside on D-galactose-induced liver injury in mice and its underlying mechanisms.METHODS C57BL/6J mice were randomly assigned to the normal group,the model group,the vitamin E group(100 mg/kg),and the low-dose and high-dose verbascoside groups(40,80 mg/kg),with 10 mice in each group.Simultaneous administration of medicine and subcutaneous injection of D-galactose(600 mg/kg)went on among the groups except the normal group for 8 weeks.Serum ALT,AST,ALP activities,along with TBil levels were measured using biochemical kits.Hepatic GSH,MDA concentrations,as well as SOD and GSH-Px activities were quantified.Liver pathological morphology was evaluated by HE staining,while hepatic fibrosis area was assessed using Sirius red staining.Western blot analysis determined hepatic expression of IL-6,IL-1β,TNF-ɑ,TLR4,NF-κB p65,IκBɑ and p-IKBɑ proteins.RESULTS Compared to the model group,the groups treated with vitamin E or verbascoside demonstrated significantly reduced body weight(P＜0.05,P＜0.01);increased hepatic index(P＜0.05,P＜0.01);decreased serum activities of ALT,AST and ALP alongsided reduced TBil levels(P＜0.05,P＜0.01);attenuated pathological damage of liver tissue and fibrosis severity;reduced hepatic MDA level(P＜0.05,P＜0.01);and elevated GSH level with enhanced SOD and GSH-Px activities(P＜0.05,P＜0.01).Furthermore,the high-dose verbascoside group showed significantly decreased hepatic expressions of IL-6,IL-1 β,TNF-ɑ,TLR4,NF-κB p65,and p-IKBɑ/IKBɑ proteins(P＜0.05,P＜0.01).CONCLUSION Verbascoside improves D-galactose-induced liver injury through its antioxidant activity,anti-inflammatory effects,and suppression of the TLR4/NF-κB signaling pathway.

Objective To study the protective effects and mechanism of sacubitril(Sac)/valsartan(Val)on cardiomyocytes of rabbits with heart failure induced by doxorubicin(DOX).Methods Thirty New Zealand rabbits were selected to establish DOX-induced heart failure rabbit model.Twenty-five rabbits with successful modeling were randomly assigned to model group(DOX group,n=9),DOX+Val group(n=8),and DOX+Sac/Val group(n=8);and another 8 New Zealand rabbits were selected as blank group.The DOX+Val group was gavaged with 4.65 mg/kg Val suspension each time,the DOX+Sac/Val group was gavaged with 9.3 mg/kg Sac/Val suspension each time,and the blank group and DOX group were gavaged with equal volume of distilled water each time.Each group was gavaged twice a day for 8 weeks.After 8 weeks of administration,echocardiography was used to measure left ventricular end-diastolic diameter(LVDD),left ventricular end-systolic diameter(LVSD),left ventricular ejection fraction(LVEF),and left ventricular fractional shortening(LVFS).The heart mass index(HMI)and left ventricular mass index(LVMI)were calculated.The pathological morphology and myocardial fibrosis of myocardial tissue were observed by hematoxylin-eosin(H-E)and Masson staining.The ultrastructure of cardiomyocytes was observed by transmission electron microscope.Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL)staining was used to observe cardiomyocytes apoptosis and apoptosis rate was calculated.Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of N-terminal pro-brain natriuretic peptide(NT-proBNP),high-sensitivity cardiac troponin I(Hs-cTNI),angiotensin Ⅱ(Ang Ⅱ),aldosterone(ALD),atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP),cyclic guanosine monophosphate(cGMP),and protein kinase G(PKG)in serum.Quantitative polymerase chain reaction(qPCR)was used to detect the expression of natriuretic peptide receptor A(NPR-A),cGMP-specific phosphodiesterase 5A(PDE5A[cGMP]),PKG,B-cell lymphoma 2(Bcl-2),Bcl-2 associated X protein(Bax),and cysteine aspartate protease 3(caspase 3)mRNA in myocardial tissue.Western blotting was used to detect the expression of phosphorylated cAMP response element-binding protein(p-CREB),phosphorylated Bcl-2 related death promoting factor(p-Bad),Bcl-2,Bax,and caspase 3 proteins in myocardial tissue.Results Compared with the blank group,the LVDD and LVSD in the DOX group were increased(both P<0.01),the LVEF and LVFS were decreased(both P<0.01)and the HMI and LVMI were increased(both P<0.01);the apoptosis and apoptosis rate of cardiomyocytes were increased(P<0.01);the levels of NT-proBNP,Hs-cTNI,Ang Ⅱ,ALD,ANP,BNP,cGMP and PKG and the expression of NPR-A,PDE5A(cGMP),PKG,p-CREB,Bax and caspase 3 were all increased(all P<0.01),while the expression of Bcl-2 was decreased(P<0.01),and the expression of p-Bad had no significant difference(P>0.05).Compared with the DOX group,the LVDD and LVSD of the DOX+Sac/Val group and DOX+Val group were decreased(all P<0.01),the LVEF and LVFS were increased(all P<0.01)and the HMI and the LVMI were decreased(all P<0.01);the apoptosis and apoptosis rate of cardiomyocytes were decreased(all P<0.01);the levels of NT-proBNP,Hs-cTNI,Ang Ⅱ,ALD,ANP,BNP,cGMP and PKG and the expression of NPR-A,PDE5A(cGMP),PKG,Bax and caspase 3 were all decreased(all P<0.01),while the expression of Bcl-2 was increased(P<0.01);and the expression of p-CREB and p-Bad was increased in the DOX+Sac/Val group(both P<0.01),but there was no significant difference in the DOX+Val group(both P>0.05).Compared with the DOX+Val group,the DOX+Sac/Val group showed a decrease in all indicators except for LVEF,LVFS,NPR-A,ANP,BNP,cGMP,PDE5A(cGMP),PKG,p-CREB,p-Bad,and Bcl-2,which were all elevated(all P<0.05).Myocardial pathology and transmission electron microscopy showed that Sac/Val effectively protected cardiomyocytes,reduced cardiomyocytes apoptosis and myocardial fibrosis,and these effects were significantly better than those of Val.Conclusion Sac/Val can effectively reduce cardiomyocytes apoptosis,improve cardiac function and reduce myocardial fibrosis in rabbits with heart failure,and these effects are superior to Val.Its mechanism may be related to activating the NPR-A/cGMP/PKG signaling pathway and inhibiting renin-angiotensin-aldosterone system.

Objective: This study aimed to explore the correlation between balance function and core muscle activation in patients with adolescent idiopathic scoliosis (AIS), compared to healthy individuals. Methods: A total of 24 AIS patients and 25 healthy controls were recruited. The limits of stability (LOS) test were conducted to assess balance function, while surface electromyography was used to measure the activity of core muscles, including the internal oblique, external oblique, and multifidus. Diaphragm thickness was measured using ultrasound during different postural tasks. Center of pressure (COP) displacement and trunk inclination distance were also recorded during the LOS test. Results: AIS patients showed significantly greater activation of superficial core muscles, such as the internal and external oblique muscles, compared to the control group (p < 0.05). Diaphragm activation was lower in AIS patients during balance tasks (p < 0.01). Although no significant difference was observed in COP displacement between the groups, trunk inclination was significantly greater in the AIS group during certain tasks (p < 0.05). Conclusion These findings suggest distinct postural control patterns in AIS patients, highlighting the importance of targeted interventions to improve balance and core muscle function in this population.
