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.

Background/Aims: Dysregulated cholesterol metabolism is a hallmark of hepatocellular carcinoma (HCC) that drives tumor initiation and progression. However, clinical targeting of cholesterol metabolism has yielded limited benefits due to stringent feedback in tumor cells. Identifying a central mediator capable of restoring cholesterol homeostasis within the cell’s intrinsically fine-tuned regulatory framework is urgently needed. Methods: We integrated a proteomic dataset from patients with cholesterol-dysregulated HCC into a global cholesterol metabolic regulatory network to identify potential therapeutic targets for disrupted cholesterol homeostasis. The prognostic significance of the candidate targets was further validated in an independent cohort through immunohistochemistry. Functional and mechanistic studies were conducted in vitro using HCC cell lines and in vivo using mouse models. The pharmacological efficacy of the candidate agent was evaluated in both subcutaneous and orthotopic HCC mouse models. Results: ER lipid raft-associated 1 (ERLIN1), a pivotal regulator of cholesterol metabolism reprogramming, was identified as an independent favorable prognostic indicator in HCC. ERLIN1 constrains HCC progression both in vitro and in vivo by stabilizing the INSIG1–SCAP–SREBP2 axis and maintaining the metabolic balance of intracellular cholesterol. Under hypoxia, impaired factor-inhibiting hypoxia-1-dependent hydroxylation of ASB11 at asparagine residues 90 and 92 enhances ASB11-mediated ERLIN1 degradation. Pharmacological targeting of this axis using zoledronic acid (ZoA) attenuated HCC progression by weakening the ASB11–ERLIN1 interaction and restoring cholesterol homeostasis. Conclusions ERLIN1 represents a druggable metabolic vulnerability in cholesterol-dysregulated HCC. Targeting the ASB11–ERLIN1 axis with the clinically approved ZoA reestablishes cholesterol homeostasis and offers a promising therapeutic strategy to overcome the current limitations of cholesterol-targeted HCC therapies.

Objective:To investigate the role and possible mechanism of tripartite motif-containing protein 72 (Trim72) in acute viral myocarditis (AVMC) in mice.Methods:A mouse model of AVMC was established by intraperitoneal injection of Coxsackievirus B3 (CVB3, 2.0 × 10 5 PFU/mouse). Forty mice were randomly divided into the negative control (NC) + phosphate-buffered saline (PBS) group (NC+PBS group), Trim72 overexpression + PBS group (Trim72 + PBS group), NC + CVB3 group, and Trim72 + CVB3 group ( n = 10). Fourteen days before modeling, mice in each group were injected with adeno-associated virus type 9 vector (AAV9) encoding either negative control or Trim72 overexpression (5.0 × 10 11 VG/mouse) via tail vein. Subsequently, PBS or CVB3 was injected intraperitoneally in the PBS and CVB3 groups, respectively. After seven days, the surviving mice were euthanized, and the heart and serum samples were collected. HE and TUNEL staining were used to observe the cardiac pathological changes and cardiomyocyte apoptosis, respectively. The mRNA expression levels of Trim72 and pro-inflammatory cytokines TNF-α, IL-6, and IL-1β in myocardial tissues of each group were detected by RT-qPCR. The protein levels of cTnI, TNF-α, IL-6, and IL-1β in serum were detected by ELISA. The expression levels of Trim72, apoptosis-related proteins (Bax, Bcl-2, Cleaved caspase-3, Caspase-3), TLR4, p-p65, and p65 were detected by Western blot. Results:The protein and mRNA expression levels of Trim72 in myocardial tissues of mice in the NC+CVB3 group were significantly downregulated compared with those in the NC + PBS group ( P<0.05). Compared with the NC + CVB3 group, Trim72 overexpression significantly increased the protein and mRNA expression of Trim72 in myocardial tissues ( P<0.05), ameliorated myocardial inflammatory injury, decreased the apoptotic index of cardiomyocytes ( P<0.05), and reduced the levels of pro-inflammation cytokines TNF-α, IL-6, and IL-1β in the myocardium and serum ( P<0.05). Additionally, Trim72 overexpression also downregulated the protein expression of Bax, Cleaved caspase-3/Caspase-3, TLR4, and p-p65, and upregulated the protein expression of Bcl-2 in myocardial tissues ( P<0.05). There was no significant difference in the indexes of mice between the NC + PBS and Trim72 + PBS groups ( P>0.05). Conclusions:Trim72 overexpression attenuates AVMC in mice by inhibiting myocardial inflammatory injury and apoptotic imbalance, and the mechanism may be related to the negative regulation of the TLR4/NF-κB signaling pathway.

Objective:To prepare ((2-(2-chlorophenyl)-3-(4-((2- 18F-fluoroethyl)oxy)phenyl)-5, 6, 7, 8-tetrahydrooxepino[3, 2-c]pyrazol-8-yl)amino)methanoic acid methyl ester ( 18F-JR-1001) and evaluate its binding affinity to the cannabinoid type 1 receptor (CB1R). Methods:18F-JR-1001 was synthesized using an integrated automated synthesis module, and its radiochemical yield (RCY) and molar activity were determined. Cell-specific uptake, lipid-water partition coefficient (log P), competitive binding assays, and in vitro stability tests were performed. Rimonabant-fed rat models (blocking group) with pre-occupied CB1R were established. Radioautography and microPET/CT imaging were conducted on both the blocking group and normal Sprague-Dawley (SD) rats to evaluate the brain uptake of 18F-JR-1001 and its blood-brain barrier (BBB) penetration capability. Results:The RCY of the synthetic 18F-JR-1001 after decay correction was (32.5±9.2)% ( n=10), with the molar activity of (194.6±67.3)GBq/μmol. Cell experiments demonstrated that 18F-JR-1001 exhibited specificity for CB1R, with log P of 3.40±0.11 ( n=3) and half-maximal inhibitory concentration of 0.975nmol/L. Within 3h at 37℃, the radiochemical purity of 18F-JR-1001 in physiological saline and blood remained above 92%, with no significant radioactive by-product peaks observed. Radioautography showed that the whole brain uptake of 18F-JR-1001 in the blocking group was 65.6% of that in normal SD rats. MicroPET/CT imaging showed that the mean whole brain uptake of 18F-JR-1001 in the blocking group was 0.4706, which was lower than that in normal SD rats (1.0561). Additionally, continuous scanning for 60min demonstrated that 18F-JR-1001 exhibited good BBB penetration capability. Conclusion:The synthesized 18F-JR-1001 meets the requirements of production and application, and is proved the potential as a CB1R-targeted tracer in the in vitro experiments, microPET/CT imaging and radioautography.

Objective:To explore the intimal injury of two kinds of hemostatic clips under different clamping forces, and to optimize and verify the calculation formula of minimum occlusion force (MOF), so as to provide theoretical basis for selecting appropriate hemostatic clips to reduce vascular injury.Methods:A total of 96 male SD rats with body weight ranging from 280 to 300 g (Animal Experimental Center of Shanxi Medical University) were randomly assigned to metal hemostatic clip group ( n=48) and disposable hemostatic clip group ( n=48) by random number table method. Each group was further divided into four subgroups with clamping forces of 0.3, 0.6, 0.9 and 1.2 N for abdominal aortic injury experiments. The damage to the vascular intima was observed under a scanning electron microscope. A vascular closure model was established for mathematical analysis to derive the theoretical calculation formula of the arterial blood management factor (MOF). According to blood pressure (BP), blood vessel diameter (D) and hemostatic clamp width (W), the average values of theoretical and actual MOF data were analyzed by paired t test to verify the accuracy of the formula. From January 2021 to December 2022, six patients (with 12 branch arteries) who presented with oral and maxillofacial malignancies at the Department of Oral and Maxillofacial Surgery, Shanxi Medical University School and Hospital of Stomatology, were included to validate the accuracy of the MOF formula. Results:Under electron microscopy, when the clamping force was 0.3 N, the one-time hemostatic clip caused very little damage to the vascular intima (grade 1 injury), with only a few folds being flattened. When the clamping force was 0.6 N, both types of hemostatic clips caused partial peeling of the intima surface (grade 2-3 injury). However, when the clamping force was adjusted to 0.9 and 1.2 N, the damage caused by both types of hemostatic clips was more severe (grade 3-4 injury), with large areas of intima peeling or even disappearance. In some specimens of the metal hemostatic clip group, the damage even reached the muscular layer. Vascular closure model analysis showed that MOF=2×(1/2×π×D×W×BP), the mean diameter of abdominal aorta of 24 SD rats was (1.41±0.07) mm, the blood pressure was (83.29±11.56) mmHg (1 mmHg=0.133 kPa). The theoretical MOF value was (0.096±0.015) N, the actual clamping force (ACF) was (0.095±0.012) N, there was no statistical significance between the two groups ( t=-0.35, P=0.725). In clinical application, the MOF calculation formula was used to select the appropriate hemostatic clip for 12 arteries, successfully blocking the blood flow, verifying the accuracy of the formula. Conclusions:Hemostatic clips can cause damage to the inner membrane of blood vessels, and the greater the clamping force, the more severe the damage. Disposable hemostatic clips have certain advantages in avoiding excessive damage to the inner membrane of blood vessels. The theoretical MOF calculation formula has a certain degree of reliability and can be used as a reference to select the appropriate hemostatic clip with low damage.

Objective:To analyze clinical indicators and imaging data of hospitalized pneumonia patients and develop prediction models for length of hospital stay based on CT radiomics features and clinical indicators.Methods:Patients admitted to the First Clinical School of Hainan Medical University for pneumonia treatment between November 2020 and May 2024 were enrolled. Clinical data and CT imaging were collected, and radiomics features were extracted. Patients were divided into three groups based on the length of stay (<8 d, 8-28 d,>28 d, and poor prognosis). Three prediction models were constructed using logistic regression (LR): clinical features model, imaging features model and a combined clinical and imaging features model. The predictive performance of three models was evaluated using the area under the receiver operating characteristic (ROC) curve and DeLong test, followed by feature analysis. The Kappa test was used to compare the consistency of the overall classification.Results:A total of 343 subjects were included, with an average age of 61.46±20.98 years. The area under the curve (AUC) values of the combined model in different hospitalization duration classifications (<8 d, 8-28 d,>28 d, and poor prognosis) were 0.73, 0.65 and 0.78 in the training set, and 0.71, 0.65 and 0.76 in the validation set, respectively. The AUC values of the clinical feature model in different hospitalization duration classifications were 0.63, 0.64 and 0.73 in the training set, and 0.60, 0.52 and 0.63 in the validation set, respectively. The AUC values of the imaging feature model in different hospitalization duration classifications (<8 d, 8-28 d,>28 d, and poor prognosis) were 0.67, 0.66 and 0.73 in the training set, and 0.68, 0.54 and 0.66 in the validation set, respectively. The DeLong test results showed that the combined model outperformed other models in hospitalization duration classification (validation set AUC, all P<0.05, Bonferroni correction). Kappa test results showed that the combined model achieved the highest consistency between predicted classifications and actual hospitalization classifications ( K=0.615). Shape features, texture features and clinical features all contributed proportionally to the combined model. Conclusion:The combined model integrating radiomics features with clinical indicators can significantly enhance the predictive efficacy for the length of hospitalization in pneumonia patients.
