The theory of constitution in traditional Chinese medicine （TCM） has emerged as a new discipline in recent years. Constitution plays a vital role in the onset，progression，transformation，and prognosis of diseases. At present，some clinical scholars have adopted a novel diagnostic and treatment model of "constitution differentiation-disease identification-syndrome differentiation"，in which constitution is regarded as a core element throughout the diagnostic and therapeutic process. Constitution is closely associated with etiology，onset，pathogenesis，syndrome differentiation，and treatment. Against this background，the construction of animal models based on constitution holds far-reaching significance for advancing clinical research. This paper focuses on the construction and evaluation of rodent models with Qi-deficiency constitution，aiming to explore how to further induce Qi-deficiency syndromes and related disease states on the basis of Qi-deficiency constitution models，thereby developing an integrated animal model that embodies the trinity of "constitution-disease-syndrome". The establishment of this model not only provides a solid experimental foundation for the development of new therapies and drugs in TCM targeting specific constitutions，diseases，and syndromes，but also greatly promotes the modernization and scientific advancement of TCM theory. By comprehensively applying multidisciplinary technologies and methods，the study evaluates the model's validity，reliability，and practicality，with the aim of opening new avenues for future research in TCM and promoting the development of the field.

Background: and Purpose Ruptured intracranial aneurysms (RIA) are associated with a mortality rate of up to 40% in the Chinese population, highlighting the critical need for targeted treatment interventions for at-risk individuals. Although the impact of aldehyde dehydrogenase 2 (ALDH2) gene mutations on susceptibility to intracranial aneurysms (IA) is well documented, the potential connection between ALDH2 rs671 single-nucleotide polymorphism (SNP) and RIA remains unexplored. Given the increased prevalence of ALDH2 gene mutations among Chinese Han individuals, it is clinically relevant to investigate the link between ALDH2 rs671 SNP and IA rupture. Methods: A prospective study was conducted on 546 patients diagnosed with IA to investigate the association between ALDH2 rs671 SNP and the risk of IA rupture. Results: The ALDH2 rs671 SNP (ALDH2*2) was significantly more prevalent in patients with unruptured IA (UIA) than in those with RIA (32.56% vs. 18.58%, P=0.004). Multivariate logistic regression analysis revealed that people with the ALDH2 mutation (ALDH2*1/*2 and ALDH2*2/*2 gene type) had a significantly reduced odds ratio (OR=0.49; 95% confidence level [CI] 0.27–0.88; P=0.018) for RIAs. Age-specific subgroup analysis indicated that the ALDH2 mutation provided a stronger protective effect in individuals aged 60 years and above with IA compared to those under 60 years old (OR=0.38 vs. OR=0.52, both P<0.05). Conclusion The incidence of RIA was significantly higher in individuals with a normal ALDH2 gene (ALDH2*1/*1) than in those with an ALDH2 rs671 SNP (ALDH2*1/*2 or ALDH2*2/*2). ALDH2 rs671 SNP may serve as a protective factor against RIA in the Chinese Han population.

OBJECTIVE: Hepatocellular carcinoma (HCC) is sensitive to ferroptosis, a new form of programmed cell death that occurs in most tumor types. However, the mechanism through which ferroptosis modulates HCC remains unclear. This study aimed to investigate the oncogenic role and prognostic value of FANCD2 and provide novel insights into the prognostic assessment and prediction of immunotherapy. METHODS: Using clinicopathological parameters and bioinformatic techniques, we comprehensively examined the expression of FANCD2 macroscopically and microcosmically. We conducted univariate and multivariate Cox regression analyses to identify the prognostic value of FANCD2 in HCC and elucidated the detailed molecular mechanisms underlying the involvement of FANCD2 in oncogenesis by promoting iron-related death. RESULTS: FANCD2 was significantly upregulated in digestive system cancers with abundant immune infiltration. As an independent risk factor for HCC, a high FANCD2 expression level was associated with poor clinical outcomes and response to immune checkpoint blockade. Gene set enrichment analysis revealed that FANCD2 was mainly involved in the cell cycle and CYP450 metabolism. CONCLUSION To the best of our knowledge, this is the first study to comprehensively elucidate the oncogenic role of FANCD2. FANCD2 has a tumor-promoting aspect in the digestive system and acts as an independent risk factor in HCC; hence, it has recognized value for predicting tumor aggressiveness and prognosis and may be a potential biomarker for poor responsiveness to immunotherapy.

OBJECTIVE: To investigate chronic hepatitis C virus (HCV) infection's effect on gestational liver function, pregnancy and delivery complications, and neonatal development. METHODS: A total of 157 HCV antibody-positive (anti-HCV[+]) and HCV RNA(+) patients (Group C) and 121 anti-HCV(+) and HCV RNA(-) patients (Group B) were included as study participants, while 142 anti-HCV(-) and HCV RNA(-) patients (Group A) were the control group. Data on biochemical indices during pregnancy, pregnancy complications, delivery-related information, and neonatal complications were also collected. RESULTS: Elevated alanine aminotransferase (ALT) rates in Group C during early, middle, and late pregnancy were 59.87%, 43.95%, and 42.04%, respectively-significantly higher than Groups B (26.45%, 15.70%, 10.74%) and A (23.94%, 19.01%, 6.34%) ( P < 0.05). Median ALT levels in Group C were significantly higher than in Groups A and B at all pregnancy stages ( P < 0.05). No significant differences were found in neonatal malformation rates across groups ( P > 0.05). However, neonatal jaundice incidence was significantly greater in Group C (75.16%) compared to Groups A (42.25%) and B (57.02%) ( χ ² = 33.552, P < 0.001). HCV RNA positivity during pregnancy was an independent risk factor for neonatal jaundice ( OR = 2.111, 95% CI 1.242-3.588, P = 0.006). CONCLUSIONS Chronic HCV infection can affect the liver function of pregnant women, but does not increase the pregnancy or delivery complication risks. HCV RNA(+) is an independent risk factor for neonatal jaundice.

Objective:To investigate the effect of securinine(SEC)on apoptosis of the human colon cancer cell line SW620,and to elucidate its possible mechanism.Methods:The nude mice with subcutaneously transplanted tumor were divided into control group(n=6),oxaliplatin(OXA)group(n=7),and SEC group(n=7).The volume and mass of subcutaneous tumors in the nude mice were measured in various groups,and the tumor inhibitory rates in various groups were calculated.The SW620 cells were treated with different doses(5-120 μmol·L-1)of SEC for 12,24,48,and 72 h,respectively.Cell counting kit-8(CCK-8)assay was used to assess the survival rates of cells in various groups,and the optimal doses of SEC were confirmed.The SW620 cells were divided into control group,20 μmol·L-1 SEC group,40 μmol·L-1SEC group,and 40 μmol·L-1OXA group.TUNEL staining method and flow cytometry were used to detect the apoptotic rates of cells in various groups.JC-1 staining was used to detect the mitochondrial membrane potentials of cells in various groups,and 2',7'-dichlorodi-hydrofluorescin diacetate(DCFH-DA)fluorescence staining and flow cytometry were used to measure the reactive oxygen species(ROS)levels in the cells in various groups.Western blotting method was used to detect the expression levels of cytochrome C,B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),c-Jun N-terminal kinase(JNK),phosphorylated JNK(p-JNK),mitogen-activated protein kinase p38,phosphorylated p38(p-p38),extracellular signal-regulated kinase(ERK)and phosphorylated ERK(p-ERK)proteins in the cells in various groups.Results:Compared with control group,the volume and mass of subcutaneously transplanted tumors in the nude mice in SEC group were significantly decreased(P＜0.05 or P＜0.01 or P＜0.001);the inhibitory rates of tumor in SEC group and OXA group were 20.42％and 6.50％.The CCK-8 assay results showed that compared with 0 μmol·L-1 SEC,when the SEC dose exceeded 20 μmol·L-1,the survival rates of SW620 cells were significantly decreased(P＜0.001).The optimal condition for subsequent experiments was set as doses of 20 μmol·L-1SEC and 40 μmol·L-1SEC,and duration of 24 h.The TUNEL results showed that compared with control group,the apoptotic rates of cells in 20 and 40 μmol·L-1 SEC groups were significantly increased(P＜0.05 or P＜0.001).The results of flow cytometry showed that compared with control group,the apoptotic rate in 40 μmol·L-1SEC group was significantly increased(P＜0.001).The JC-1 staining results showed that compared with control group,the mitochondrial membrane potentials of cells in 20 and 40 μmol·L-1 SEC groups were significantly decreased(P＜0.001).Compared with control group,the levels of ROS detected by DCFH-DA fluorescence staining in the cells of 20 and 40 μmol·L-1 SEC groups and 40 μmol·L-1 OXA group were significantly increased(P＜0.001),while the level of ROS detected by flow cytometry in 40 μmol·L-1SEC group was significantly increased(P＜0.05).Compared with control group,the expression levels of Bcl-2 protein in the cells in 20 and 40 μmol·L-1 SEC groups and 40 μmol·L-1 OXA group were decreased(P＜0.01),while the expression levels of cytochrome C and Bax proteins were increased(P＜0.001).Compared with control group,the ratios of p-JNK/JNK,p-p38/p38 and p-ERK/ERK in 20 and 40 μmol·L-1 SEC groups were significantly increased(P＜0.05 or P＜0.01 or P＜0.001).Conclusion:SEC can inhibit the proliferation of SW620 cells,increase the cellular ROS levels,reduce the mitochondrial membrane potential,and induce the mitochondrial apoptosis;its mechanism may be related to the regulation of the mitogen-activated protein kinase(MAPK)signaling pathway.

Objective:To discuss the regulatory role of complement alternative pathway in mouse colorectal cancer(CRC)liver metastasis model based on bioinformatics methods,and to clarify its mechanism through experimental verification.Methods:Using"CRC liver metastasis"as the keyword,the GSE81558 dataset was retrieved from Gene Expression Omnibus(GEO)database,including normal colon tissue samples,CRC tissue samples and CRC liver metastasis tissue samples.Bioinformatics methods were used to analyze and screen differentially expressed genes(DEGs).Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis were performed using R and Cytoscape software,and the results were visualized.Search Tool for the Retrieval of Interacting Genes/Proteins(STRING)database was used to evaluate protein-protein interactions(PPIs)of DEGs and construct PPI network.Twelve C57BL/6 mice were injected with SL4 tumor cells into spleen,and the liver tissues were collected at 0,7 and 14 d.Real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of complement pathway-related genes in liver metastatic foci.The CRC liver metastasis mouse model was used to verify the complement signaling pathway.The mice were divided into control group,factor B knockout group(FB-/-)and C4 factor knockout group(C4-/-),and there were 6 mice in each group.The liver weights of the mice were measured;HE staining was used to detect the percentage of metastatic area in liver tissue in control group and FB-/-group;immunohistochemistry was used to detect macrophage infiltration in liver tissue in control group and FB-/-group,and the percentage of macrophage infiltration was calculated.Results:The distances between normal colon tissue samples and CRC tissue samples,as well as between CRC tissue samples and CRC liver metastasis tissue samples were far,indicating significant differences between samples,allowing subsequent analysis of DEGs.A total of 1 908 DEGs were screened in the dataset comparing normal colon tissue samples and CRC tissue samples,including 771 up-regulated DEGs and 1 137 down-regulated DEGs.Twenty-three up-regulated DEGs and 100 down-regulated DEGs were identified in the dataset comparing CRC and CRC liver metastasis.The GO functional enrichment analysis results showed that compared with normal colon tissue samples,DEGs in CRC samples were mainly enriched in biological processes(BP)related to cell cycle and mitosis,including mitotic cell cycle process,cell division,response to hormone,mitotic nuclear division and response to lipid.Compared with CRC samples,the DEGs in CRC liver metastasis samples were mainly enriched in coagulation-related BP,including platelet degranulation,blood coagulation regulation,acute-phase response,hemostasis regulation and coagulation regulation.The KEGG pathway enrichment analysis results showed that compared with normal colon tissue samples,the DEGs in CRC tissue samples were mainly enriched in cell cycle and p53 signaling pathways.Compared with CRC tissue samples,the DEGs in CRC liver metastasis tissue samples were mainly enriched in complement,coagulation cascade and metabolism-related signaling pathways.The Hub genes identified in PPI network were related to blood proteins.The RT-qPCR results showed that compared with 0 d group,the mRNA expression level of complement related genes complement 1q(C1q)in liver metastatic foci tissue sampres in 7 d group was significantly decreased(P<0.05),the mRNA expression levels of complement 3(C3),complement 5(C5),FB,and factor D(FD)were significantly increased(P<0.05 or P<0.01),the mRNA expression levels of complement pathway-related genes C1q,complement 2(C2),C3,complement fragment 3a receptor(C3aR),C5,complement fragment 5a receptor(C5aR),decay-accelerating factor(DAF),FB and FD in liver metastatic foci tissue sampres in 14 d group were significantly increased(P<0.05 or P<0.01).Compared with control group,the liver weight of the mice in FB-/-group was significantly decreased(P<0.01),while there was no significant difference was observed in C4-/-group(P>0.05).The HE staining results showed that compared with control group,the liver metastatic foci in FB-/-mice were significantly decreased,and the percentage of metastatic area was decreased(P<0.01).The immunohistochemistry results showed that compared with control group,the macrophage infiltration in liver metastatic foci of the mice in FB-/-group was reduced,and the percentage of macrophage infiltration was decreased(P<0.01).Conclusion:Complement cascade is associated with CRC liver metastasis,and the alternative complement pathway regulates CRC liver metastasis,suggesting this pathway may serve as a potential therapeutic target for CRC liver metastasis.

OBJECTIVE:The quality of systematic reviews/meta-analyses directly affects the reliability of clinical decision-making basis.Currently,there is no literature quality research on the systematic reviews/meta-analyses of platelet rich plasma versus hyaluronic acid in the treatment of knee osteoarthritis both domestically and internationally.This article will comprehensively evaluate the methodological quality,reporting quality,and evidence quality of the systematic reviews/meta-analyses of platelet rich plasma versus hyaluronic acid in the treatment of knee osteoarthritis.METHODS:Computer searches were conducted on CNKI,WanFang Data,VIP,CBM,PubMed,Embase,and The Cochrane Library.From the establishment of the database until January 24,2024,all systematic reviews/meta-analyses treated with platelet rich plasma versus hyaluronic acid for knee osteoarthritis were collected.Two evaluators independently conducted literature screening and data extraction,and used the AMSTAR 2,PRISMA 2020,and GRADE systems to evaluate and summarize the methodological,reporting,and evidence quality of the included systematic reviews/meta-analyses.RESULTS:A total of 18 qualified systematic reviews/meta-analyses were included,and the results showed that the efficacy and safety of platelet rich plasma might be better than that of hyaluronic acid.The methodological quality of all 18 studies was extremely low;4 reports had poor quality and relatively serious information defects,while 14 reports had moderate quality and some information defects.Among the 275 outcome measures of 16 systematic reviews/meta-analyses,there were 9 medium quality evidence,90 low-quality evidence,and 176 extremely low-quality evidence,with no high-quality evidence.CONCLUSION:At present,the quality of systematic reviews/meta-analyses literature on the treatment of knee osteoarthritis with platelet rich plasma versus hyaluronic acid is relatively low.In the future,the authors of the systematic reviews need to strictly follow the entries of quality evaluation tools such as AMSTAR 2 and PRISMA 2020 in terms of plan registration,research type explanation,retrieval strategy,exclusion list,research site and funding source,bias risk analysis,publication bias evaluation,and public information acquisition,and conduct evidence quality evaluation on the combined results of the systematic reviews/meta-analyses to provide more reliable and rigorous evidence-based basis for clinical practice.

Objective:To evaluate the effect of 5th generation mobile communication technology(5G) remote robot-assisted cholecystectomy on postoperative recovery and quality of life in patients with gallstones.Methods:Clinical data of patients who underwent 5G remote robotic cholecystectomy(20 cases) vs traditional robotic cholecystectomy(20 cases) at Gansu Provincial People's Hospital from May to September 2023 were retrospectively analyzed. Intraoperative and postoperative related indexes were compared between the two groups, and changes in pain analog scores before, 12 hours, and 24 hours after surgery, and global quality of life (GIQLI) scores before and 3 months after surgery were evaluated.Results:There was no significant difference between the two groups in terms of intraoperative and postoperative conditions (intraoperative blood loss, operative time, time to exhaustion, and length of hospital stay). Patients' pain analog scores at 12 and 24 hours postoperatively were lower than preoperatively, but the differences were not statistically significant( P>0.05). In addition, there was no significant difference in recovery indicators between the two groups compared to the control group ( P>0.05). Conclusion:The postoperative recovery metrics of 5G tele-robotic-assisted cholecystectomy were consistent with the results of conventional robotic surgery.
