This paper systematically reviews the current status of integrated traditional Chinese and western medicine in the treatment of Helicobacter pylori （Hp） infection， as well as recent progress in clinical and basic research both in China and internationally. It summarizes the advantages of traditional Chinese medicine （TCM） in Hp infection management， including improving Hp eradication rates， enhancing antibiotic sensitivity， reducing antimicrobial resistance， decreasing drug-related adverse effects， and ameliorating gastric mucosal lesions. These advantages are particularly evident in patients who are intolerant to bismuth-containing regimens， those with refractory Hp infection， and individuals with precancerous gastric lesions. An integrated， whole-process management approach and individualized， staged comprehensive treatment strategies combining TCM and western medicine are proposed for Hp infection. Future prevention and control of Hp infection should adopt an integrative Chinese-western medical strategy， emphasizing prevention， strengthening primary care， implementing proactive long-term monitoring， optimizing screening strategies， and advancing the development of novel technologies and mechanistic studies of Chinese herbal interventions. These efforts aim to provide a theoretical basis and practical pathways for the establishment and improvement of Hp infection prevention and control systems.

Objective To investigate the post-discharge exercise behavior and factors influencing moderate to vigorous intensity physical activity (MVPA) in patients undergoing lung surgery. Methods A total of 2874 patients from the large prospective, observational perioperative lung symptom study cohort (CN-PRO-Lung 3) in the Department of Thoracic Surgery at Sichuan Cancer Hospital between April 7, 2021, and January 31, 2024, were selected as the survey subjects. A survey was conducted using the Investigation of Exercise Behavior after Lung Surgery questionnaire and the International Physical Activity Questionnaire-Short Form (IPAQ-SF) among patients who underwent lung surgery. Binary logistic regression was used to analyze the factors influencing patients’ engagement in MVPA. Results A total of 702 patients were surveyed, including 252 males and 450 females, with an average age of (52.4±10.2) years. Patients with lung cancer accounted for 85.9%. Only 36.0% of the patients had regular exercise habits, while 42.3% did not engage in any physical activity. The three main barriers for postoperative exercise were physical discomfort (pain, coughing, shortness of breath, etc, 54.7%), lack of professional guidance (41.7%), and concerns about the surgical wound (28.9%). The proportions of patients engaging in vigorous, moderate, and low-intensity physical activity were 5.7%, 28.2%, and 66.1%, respectively. Multivariate analysis showed that patients with a personal annual income ≥50000 yuan (OR=1.52, 95%CI 1.01-2.29, P=0.044), high school education or above (OR=1.92, 95%CI 1.33-2.76, P<0.001), and lobectomy (OR=1.44, 95%CI 1.02-2.03, P=0.037) engaged in more MVPA. Conclusion Patients undergoing lung surgery have inadequate physical activity after discharge, particularly lacking in MVPA. Patients with higher income, higher educational levels, and lobectomy are more frequently engaged in MVPA. Measures such as symptom control, providing exercise guidance, and enhancing education on wound care may potentially improve the inadequate physical activity in lung surgery patients after discharge.

Objective: To investigate the influence of sinus morphology on the safety of hydraulic sinus floor elevation surgery and provide a biomechanical basis for clinical treatment. Methods: After approval by the Medical Ethics Committee of the institution, cone beam computed tomography imaging data from nine patients were collected. The sinus morphologies were classified into slope, flat and concave types. Three-dimensional finite element models of maxillary sinuses with the aforementioned morphologies were constructed using Mimics, Geomagic, Solidworks, and ANSYS software, followed by a simulation of the hydraulic elevation process. The sinus membrane elevation height was set at 1-6 mm. The pressure required for elevation and the equivalent, compressive, tensile, and shear stresses generated on the sinus membrane were recorded and analyzed. The equivalent stress distribution on the sinus membrane was visualized using contour plots. Results: The elevation pressure and the equivalent, compressive, tensile, and shear stresses generated on the sinus membrane increased along with the elevation height. When the sinus membrane was lifted to 6 mm, the elevation pressure was (301.17 ± 98.1) kPa, (151.85 ± 3.7) kPa, and (149.36 ± 10.31) kPa in the slope, flat and concave finite element analysis models, respectively. The equivalent stress was (1 023.86 ± 201.99) kPa in the slope sinuses, comparing with (687.91 ± 69.08) kPa and (698.27 ± 96.09) kPa in the flat and concave sinuses. Higher elevation pressure and the equivalent stress, compressive stress and shear stress values were found in the slope sinus than in the flat and concave sinuses under the same elevation height (P < 0.05). Stress distribution analysis revealed that stress was uniformly distributed in the flat sinuses, followed by concave sinuses, but asymmetrically distributed in the slope sinuses Conclusions The slope sinuses demonstrated inferior safety and efficiency compared with the flat and concave sinuses when performing hydraulic sinus floor elevation surgery.

OBJECTIVE To investigate the mechanism of isochlorogenic acid A against hepatocellular carcinoma based on the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway and multi-omics technology. METHODS The invasion rate and migration rate of human hepatocellular carcinoma HepG2 cells after 48 h of intervention with 0 （control group）， 0.25 and 0.5 mg/mL isochlorogenic acid A were examined； mRNA expression of DEP domain-containing mTOR-interacting protein （DEPTOR）， the protein expressions of mTOR， PI3K and phosphatase and tensin homologue deleted on chromosome ten （PTEN）， as well as the phosphorylation level of Akt protein were determined in the cells. Metabolomics analysis was performed using liquid chromatography-tandem mass spectrometry， and differential metabolites were screened and subjected to Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis； transcriptomics monitoring was conducted by RNA sequencing， and differentially expressed genes were screened and subjected to gene ontology （GO） and KEGG pathway enrichment analyses. RESULTS Compared with the control group， intervention with 0.25 and 0.5 mg/mL isochlorogenic acid A for 48 h significantly inhibited the invasion rate and migration rate of HepG2 cells， significantly up-regulated the mRNA expression of DEPTOR and the protein expression of PTEN， and significantly down-regulated the protein expression of PI3K and the phosphorylation level of Akt protein （except for 0.25 mg/mL isochlorogenic acid A） （ P ＜0.05）. A total of 304 differential metabolites and 212 differentially expressed genes were screened by multi-omics analysis. KEGG pathway enrichment analysis suggested that isochlorogenic acid A regulated key signaling of HepG2 cell growth mainly by inhibiting the PI3K/Akt signaling pathway， synergizing with metabolic reprogramming such as mTOR signaling pathway， ferroptosis， pentose phosphate pathway and purine/pyrimidine metabo lism. CONCLUSIONS The anti-hepatocellular carcinoma effect of isochlorogenic acid A is associated with the blockade of abnormal activation of the PI3K/Akt/mTOR signaling pathway. In addition， it may also be related to the inhibition of the pentose phosphate pathway and purine/pyrimidine metabolism， as well as the induction of ferroptosis，etc.

Objective:To investigate the effect of miR-1-3p on mitophagy in human esophageal squamous cell carcinoma (ESCC) cells and the related mechanisms.Methods:The differentially expressed miRNAs in ESCC were screened using the GEO database. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to measure miR-1-3p expression in normal esophageal epithelial cells (HET-1A) and ESCC cell lines (TE1, KYSE30, KYSE150, KYSE410, Eca109). Bioinformatics tools were utilized to predict target genes of miR-1-3p, subcellular localization was confirmed by fluorescence in situ hybridization. The targeting relationship between miR-1-3p and SLC7A11 was validated using dual-luciferase reporter assay. Cell proliferation and apoptosis were detected by CCK8 assay and flow cytometry, respectively. Furthermore, experimental validation demonstrated that overexpression of SLC7A11 rescued the presence of the miR-1-3p/SLC7A11 axis. Confocal microscopy was used to detect changes in mitochondrial autophagic lysosomes, while transmission electron microscopy was employed to observe mitophagy and morphological alterations. Western blot was conducted to evaluate the expression of autophagy-related proteins LC3 and P62. Flow cytometry was used to measure mitochondrial membrane potential and reactive oxygen species (ROS). Immunohistochemistry was applied to assess SLC7A11 expression in 133 ESCC patient tissues and 115 normal esophageal epithelial tissues. The correlation between SLC7A11 expression level and clinicopathological features was analyzed. Survival analysis was performed using the Kaplan-Meier method, and Cox proportional hazard regression models were used for multivariate analysis.Results:The expression of miR-1-3p in ESCC cells was significantly lower than that in HET-1A cells ( P＜0.05). SLC7A11 was a target gene of miR-1-3p. Transfection of miR-1-3p mimic inhibited the proliferation of ESCC cells. CCK-8 assay results showed that the proliferative capacity of KYSE30 and KYSE410 cells in the miR-1-3p mimic group (absorbance values: 2.88±0.24 and 2.88±0.18, respectively) was significantly lower than that in the miRNA mimic negative control (NC) group (3.94±0.27, P＜0.001; 4.20±0.21, P＜0.001). Meanwhile, the proliferative capacity of KYSE30 and KYSE410 cells in the miR-1-3p mimic+SLC7A11-overexpression (OE) group (absorbance values: 3.57±0.15 and 3.60±0.13, respectively) was significantly higher than that in the miR-1-3p mimic +empty vector (EV) group (2.54±0.10, P＜0.001, 2.36±0.16, P＜0.001). Additionally, transfection of miR-1-3p mimic promoted apoptosis. Flow cytometry results demonstrated that the apoptosis rates of KYSE30 and KYSE410 cells in the miR-1-3p mimic group [(9.22±0.05)% and (6.55±0.37)%, respectively] were significantly higher than those in the miRNA mimic NC group [(0.81±0.17)%, P＜0.001); (1.04±0.12)%, P＜0.001]. Conversely, the apoptosis rates of KYSE30 and KYSE410 cells in the miR-1-3p mimic + SLC7A11-OE group [(0.73±0.04)% and (1.19±0.05)%, respectively] were significantly lower than those in the miR-1-3p mimic+EV group [(9.83±0.41)%, P＜0.001); (6.09±0.17)%, P＜0.00)]. MiR-1-3p mimic downregulated SLC7A11 protein expression and the LC3Ⅱ/LC3I ratio ( P＜0.05), upregulated P62 protein expression ( P＜0.05), this phenomenon can be rescued by overexpressing SLC7A11 ( P＜0.05). Additionally, miR-1-3p mimic increased ROS levels and decreased mitochondrial membrane potential (JC-1 aggregate/monomer ratio), this phenomenon can be rescued by overexpressing SLC7A11 ( P＜0.05). SLC7A11 expression was higher in ESCC tissues compared to normal esophageal epithelial tissues ( P＜0.001), and SLC7A11 serves as an independent prognostic factor in ESCC ( HR=2.15, 95% CI: 1.27-3.65, P=0.004). Conclusion:miR-1-3p inhibits mitophagy in esophageal squamous cell carcinoma by targeting SLC7A11.

Objective:To compare the therapeutic effect of ureteroscopy(RIRS)combined with fine needle ultra fine channel percutaneous nephrolithotomy(SMP)and microchannel percutaneous nephrolithotomy(MPCNL)in the treatment of complex kidney stones.Methods:100 patients with complex kidney stones who were admitted to our hospital from March 2022 to May 2024 were divided into control group of 50 cases and study group of 50 cases by using random number table method.The control group patients received MPCNL treatment,while the study group patients received fine needle SMP combined with RIRS treatment.The clinical indicators,pain status,inflammatory stress indicators,renal function indicators,and incidence of complications between the two groups were compared.Results:Surgical time in the study group was longer than that in the control group,the intraoperative blood loss was less than that of the control group,the postoperative hospitalization time and time to get out of bed after surgery were shorter than those in the control group(P＜0.05).There was no statistically significant difference in the success rate of stone removal between the two groups(P＞0.05).The visual analog pain scale(VAS)scores in the study group were lower than those in the control group at 6 h,24 h,and 48 h after surgery(P＜0.05).Serum procalcitonin(PCT),high-sensitivity C-reactive protein(hs-CRP),cortisol(Cor),norepinephrine(NE),urea nitrogen(BUN),serum creatinine(Scr),and cystatin C(Cys C)in the study group were lower than those in the control group at 3 d after surgery(P＜0.05).There was no statistically significant difference in the incidence of complications between the two groups(P＞0.05).Conclusion:Compared with MPCNL treatment for complex kidney stones,fine needle SMP combined with RIRS can reduce intraoperative bleeding,shorten time to get out of bed and hospitalization time,alleviate inflammatory stress response,and reduce damage to kidney function and postoperative pain without increasing the incidence of complications.

The aim of this study is to explore the immunogenicity of African swine fever virus p37 recombinant protein in mice.C57BL/6J mice were immunized subcutaneously in the abdomen using p37 recombinant protein as antigen.The second immunization was performed 21 d after the first immunization.Serum-specific antibody levels were detected by ELISA;serum cytokine levels were detected using a multifactor assay technique;mice splenic lymphocytes were isolated 7 d after sec-ondary immunization,and the number of splenic lymphocytes secreting IFN-γ after recombinant protein stimulation was detected by ELISpot;and the ratio of CD4+T cells to CD8+T cells was detected by flow cytometry.The results of indirect ELISA showed that p37 recombinant protein could stimulate mice to produce high levels of specific antibodies;ELISpot showed that p37 recom-binant protein could significantly stimulate splenic lymphocytes to produce IFN-γ(P＜0.001)and activate cellular immune responses;the results of flow cytometry showed that it could signifi-cantly stimulate the differentiation of T-lymphocytes to CD4+T-lymphocytes(P＜0.001).In ad-dition,serum levels of IL-2,IL-4,IFN-γ,and TNF-α immune-related cytokines were significantly higher after the second immunization.Immunization of mice with p37 recombinant protein induced strong humoral and cellular immune responses with good immunogenicity,providing reference for the subsequent epitope identification and functional study of p37 protein and the antigen screening of ASF mRNA vaccine.

In order to establish a highly efficient,convenient,and effective circular RNA(circRNA)vaccine preparation system,enhanced green fluorescent protein(EGFP)circRNA was constructed using permuted intron exon(PIE)strategy based on type Ⅰ introns.Then,circRNA circularization rates of RNA after in vitro transcription(IVT),primary circularization(IVC1),and secondary circularization(IVC2)were compared after purification.The constructed circRNA system was fur-ther applied to porcine reproductive and respiratory syndrome virus(PRRSV),and two circRNAs based on PRRSV GP5 protein were constructed and developed for in vitro expression.Results showed that circularization rates and protein expression effects of EGFP circRNA in IVC1 RNA and IVC2 RNA were similar,but both were significantly better than those of IVT RNA.Purity of EGFP circRNA reached 74％,and purities of two PRRSV GP5 protein circRNAs constructed using this preparation system were 71％and 64％,respectively.Western blot and indirect immunofluo-rescence assay(IFA)results indicated that both of the PRRSV GP5 protein circRNAs were suc-cessfully expressed.The results demonstrated that an easy-to-operate,low-cost circRNA prepara-tion system with high circularization rate was successfully constructed.Two PRRSV GP5 protein circRNA vaccines were successfully prepared using this system and expressed efficiently,which provides a reference for the development of animal circRNA vaccines and novel candidate vaccines against PRRSV.

Objective:To investigate the differences in clinical outcomes of septic children with varying serum zinc levels,and to analyze the relationship between reduced serum zinc levels and organ dysfunction as well as 28-day mortality in septic children.Methods:This study conducted a retrospective analysis of clinical data from pediatric patients diagnosed with sepsis or septic shock in the Department of critical care medicine of the children's Hospital of Soochow University between January 2017 and December 2022.Clinical characteristics,organ dysfunction,and prognosis were compared between two groups:children with low serum zinc levels and those with normal zinc levels.Results:The serum zinc level of septic children within 24 hours of admission was 9.60(5.52,13.80)μmol/L,with 50.54%(94/186)of the children exhibiting low serum zinc levels(<10.07 μmol/L).Compared to the normal serum zinc group,the low serum zinc group had a significantly lower Pediatric Critical Illness Score(PCIS)[(78.71±9.35)vs.(85.12±8.51),P=0.005]and higher 28-day mortality(46.80%vs.14.13%,P<0.001).The low serum zinc group also had a higher proportion of invasive mechanical ventilation(64.89%vs.47.82%,P=0.019),renal replacement therapy(15.59%vs.3.26%,P=0.003),and use of vasoactive drugs(56.38%vs.30.43%,P<0.001).The rate of underlying conditions in the low serum zinc group was significantly higher than that in the normal serum zinc group(57.44%vs.36.95%,P=0.005).Additionally,the low serum zinc group had a higher incidence of disseminated intravascular coagulation(DIC),respiratory failure,acute kidney injury,shock,and multiple organ dysfunction syndrome(MODS)compared to the normal serum zinc group(P<0.05).Serum zinc levels had predictive value for 28-day mortality in septic children(AUC=0.813;95%CI:0.725～0.902;P<0.001).A serum zinc level of less than 6.950 μmol/L predicted the death of septic children with a sensitivity of 0.618 and a specificity of 0.902.Conclusion:Sepsis in children is commonly associated with low serum zinc levels,especially in those with underlying conditions such as hematologic and oncologic disorders.Sepsis patients hypozincemia with a higher incidence of DIC,respiratory failure,acute kidney injury,shock,and MODS.A serum zinc level below 6.95 μmol/L serves as a significant predictor of 28-day mortality in children with severe sepsis.

Microalgae can achieve sustainable CO2 fixation and biomass conversion,making them a green path for carbon capture and conversion.Monitoring extracellular carbonic anhydrase(CA)activity in microalgae is crucial for regulating carbon conversion efficiency.In this study,double-stranded DNA was designed as a capture probe to bind H+,which was produced by CA-catalyzed CO2 hydration.This interaction induced conformational changes in the DNA probe,enhancing fluorescence signals and thereby establishing a recognition and signal transduction mechanism for CA catalytic product.This approach enabled a novel method for measuring CA activity.The response of probe to H+was investigated using ultraviolet visible(UV-Vis)spectroscopy,circular dichroism sepctroscopy,and fluorescence spectroscopy.The experimental results indicated that the fluorescence intensity of the probe increased progressively with rising H+concentration.Using this probe,CA activity detection could be completed within 29 min,with a detection range of 0.35-17500 U/mL and a detection limit of 0.15 U/mL.Compared to traditional methods,this approach offered a lower detection limit and was suitable for analyzing and detecting extracellular CA activity in actual algal samples.
