Objective:To explore the intervention effect of Jianpifuwei granule(JPFWG)on gastric mucosal injury in rats with precancerous lesions of gastric cancer(PLGC)by regulating the IL-6/JAK/STAT3 signaling pathway and its mechanism.Methods:The PLGC model rats were established by MNNG combined with composite factors,and randomly divided into 6 groups(20 rats/group):the blank group(untreated),model group(treated with normal saline),Weimeisu group(0.05 g/mL Weimeisu),JPFWG low-dose group(JPFWG-L,0.088 g/mL),JPFWG medium-dose group(JPFWG-M,0.176 g/mL)and JPFWG high-dose group(JPFWG-H,0.351 g/mL).After being treated with Weimeisu and different doses of JPFWG for 12 weeks,the animals were anesthetized and sacrificed,and the gastric tissues were collected.The pathological changes of gastric mucosa were observed by H-E staining,and the expression levels of IL-6-mediated JAK/STAT3 signaling pathway factors(including IL-6,JAK and STAT3)and the mRNA and proteins of their downstream target genes c-Myc and cyclin D1 in gastric mucosal tissues were detected by immunohistochemistry,qPCR and WB.Results:Compared with that in the model group,the gastric mucosal inflammatory cell infiltration was reduced in the Weimeisu group and the low,medium,and high dose groups of JPFWG;pathological condition was improved,most obviously in the high dose group of JPFWG;The protein expressions of IL-6,JAK1 and STAT3 decreased significantly(P<0.05 or P<0.01).The expressions of mRNA and proteins of c-Myc and cyclin D1 in the gastric mucosal tissues of the rats in the Weimeisu group and JPFWG-H group decreased significantly(P<0.05 or P<0.01).Conclusion:JPFWG can improve the histopathological changes of gastric mucosa in rats with PLGC,and its mechanism may be down-regulating the expressions of c-Myc and cyclin D1 through regulating IL-6/JAK/STAT3 signal pathway,thus blocking inflammation-cancer transformation process.

Integrating evidence from animal experiments is a critical component of biomedical research, providing essential prior information for in-depth investigations of disease mechanisms and new drug development. Animal models have played an irreplaceable role in simulating human diseases. However, the integration of evidence from animal experiments has faced numerous challenges, including insufficient emphasis, significant heterogeneity in study designs, high publication bias, and discrepancies with clinical research practices. This paper first identifies existing issues in the original research evidence from animal experiments, such as the selection and applicability of animal models, considerations in the design of experimental studies, and factors influencing the translation of animal experimental evidence. It then discusses various methods for integrating this evidence, including systematic review and meta-analysis, overview of systematic review/umbrella review, scoping review, and evidence mapping, while highlighting recent advancements in their application. Finally, the paper addresses the main challenges currently encountered in the integration of evidence from animal experiments and proposes targeted improvement strategies aimed at enhancing the efficiency of translating research outcomes into clinical practice and promoting the advancement of evidence-based medicine. By continuously optimizing original experimental research protocols and evidence integration practices, this work aims to establish a more efficient and scientific environment for the synthesis of evidence from animal experiments, ultimately contributing to clinical trials and human health.

To explore the effect of acupuncture at Neiguan (PC 6) on the cardiovascular functions in the patient with low pulse pressure syndrome. Methods: 49 cases were randomly divided into acupuncture group and medicine group. Acupuncture group was treated by acupuncture at bilateral Neiguan (PC 6) for 3 consecutive days, and the medicine group was given intravenous drip of Shenmai Injectio for 6 consecutive days. 20ml each day. Blood pressure, pulse pressure. SV, CO. LVWL, MAP, TPR. CCP, PAWP, BV, MHR and CMBV were examined before and after treatment. 23 healthy subjects were observed as controls. Results: The pulse pressure of patients before treatment was significantly lower than that of controls (P
