Hepatic fibrosis（HF） is a common pathological link of a variety of chronic hepatic diseases， and its complex pathological mechanism and prolonged clinical course pose a major challenge to modern medicine. Modern conventional therapies for HF cannot reverse the pathological vascular remodeling of the liver， and targeted vascular treatment for HF is a current research hotspot. There is a contradiction between the inhibition of pathological repair and the promotion of physiological regeneration with a single targeted therapy. The dynamic equilibrium concept of "achieving equilibrium of Yin and Yang" of traditional Chinese medicine can provide a new treatment strategy， and multi-target traditional Chinese medicine compounds can achieve two-way regulation of pathological mechanisms. According to the research on the modernization of traditional Chinese medicine， the "collaterals and vascular system" are highly compatible in structure and function， and they can guide the treatment of HF at different stages by identifying their common pathological links in HF. The intrahepatic collaterals are an important component of the hepatic collaterals， and the theory of "hepatic collateral disease" based on this physiology has important guiding significance for the clinical diagnosis and treatment of HF. Hepatic sinusoidal obstruction caused by endothelial dysfunction in the early stage of HF is a pathological manifestation of stagnant nutrient Yin in collateral passages. It can be treated by diffusing Qi to resolve stagnation and promoting circulation to unblock collaterals. Repeated stimulation of angiogenesis by hypoxia and inflammation in the medium stage is the pathological manifestation of lingering stagnation of damp and heat in collateral passages. It can be treated by clearing and draining damp and heat， eliminating turbidity， and unblocking collaterals. Pathological vascular remodeling induced by hemodynamic abnormalities in the later stage is a pathological manifestation of the consumption of collateral passages by pathogenic toxins. At this stage with excessive pathogenic factors and deficient healthy Qi， combined therapy of dredging and nourishing is adopted to eliminate toxins， resolve blood stasis， nourish Yin， and supplement Qi simultaneously. Moreover， the holistic concept of harmony between human and nature in traditional Chinese medicine emphasizes the time， place， and treatment based on individual conditions， so the practical application of the theory should consider the specific regional characteristics. This paper aims to discuss the characteristics of pathogenesis， treatment principles， prescriptions， and medicines in different stages of HF based on the correlation between "collaterals and vascular system" as well as the theory of "hepatic collateral disease". It was proposed that Qi deficiency and collateral obstruction were the core pathogenesis of HF， and that hepatic collateral damage was the core pathological basis for the deterioration and prognosis of HF. The scientific connotation and pathogenesis evolution of collateral damage and mass generation in HF were discussed. Sichuan was taken as an example to investigate the treatment of HF according to local conditions， providing new ideas for the treatment of HF.

BACKGROUND:Formononetin demonstrates potent anti-inflammatory and antioxidant abilities.However,its protective effect on nucleus pulposus mesenchymal stem cells is not yet clear.OBJECTIVE:To investigate the effect and mechanism of formononetin on nucleus pulposus mesenchymal stem cells under an inflammatory microenvironment.METHODS:(1)Primary nucleus pulposus mesenchymal stem cells were isolated from the intervertebral discs of SD rats,and flow cytometry was performed to identify the surface markers of mesenchymal stem cells.(2)The CCK-8 assay was employed to evaluate the impact of lipopolysaccharide and formononetin on the proliferation viability of nucleus pulposus mesenchymal stem cells,aiming to determine the appropriate concentration of formononetin for subsequent cell treatments.(3)An inflammatory microenvironment was simulated by adding 5 μg/mL lipopolysaccharide to the DMEM/F-12 culture medium,and nucleus pulposus mesenchymal stem cells were treated with different concentrations of formononetin for 24 hours.Levels of inflammation markers were detected using western blot assay,real-time quantitative PCR,and immunofluorescence.Western blot assay was conducted to measure the protein levels of the nuclear factor kappa B signaling pathway.RESULTS AND CONCLUSION:(1)The nucleus pulposus mesenchymal stem cells cultured in adherent wall were shuttle-shaped with good growth status.The results of flow cytometry showed that the surface markers of mesenchymal stem cells were positive for CD29,CD44,and CD90,and the surface markers of hematopoietic stem cells were negative for CD34 and CD45.(2)The treatment with formononetin at 12.5,25,50,100,and 200 μmol/L concentrations for 24 hours had no significant proliferation inhibitory effect on nucleus pulposus mesenchymal stem cells.Compared with the lipopolysaccharide group,the cell viability of nucleus pulposus mesenchymal stem cells treated with 12.5,25,and 50 μmol/L formononetin for 24 hours was significantly increased,so formononetin at 12.5,25,and 50 μmol/L concentrations was subsequently selected as the low,medium,and high concentrations for treating nucleus pulposus mesenchymal stem cells.(3)Compared with the lipopolysaccharide group,the protein and mRNA expressions of matrix metalloproteinase-3,matrix metalloproteinase-13,and tumor necrosis factor-α in nucleus pulposus mesenchymal stem cells in the low,medium,and high concentrations of formononetin groups were significantly decreased(P＜0.05)in a dose-dependent manner.(4)Compared with the lipopolysaccharide group,the expressions of phosphorylated nuclear factor kappa B and phosphorylated nuclear factor kappa B inhibitor protein in nucleus pulposus mesenchymal stem cells in the low,medium,and high concentrations of formononetin groups were significantly decreased(P＜0.05)in a dose-dependent manner.The above results suggest that formononetin may attenuate lipopolysaccharide-induced inflammation in rat nucleus pulposus mesenchymal stem cells by inhibiting the activation of the nuclear factor kappa B signaling pathway.

Objective:To collect registered clinical research plans on TCM characteristic therapies for treating cervical spondylosis; To explore their research registration status; To provide references for future clinical trial registration and implementation.Methods:Clinical research on TCM characteristic therapies for treating cervical spondylosis was retrieved from ChiCTR, ITMCTR and Clinical Trials. gov from the establishment of the databases to July 1, 2024. Excel 2019 was used to conduct descriptive statistics on registration time, registration area and institution, funding source, research type and design scheme, research participation center and sample size, cervical spondylosis type, intervention measures, outcome indicators, reporting quality, research openness and methodological application.Results:A total of 138 clinical trials for the TCM treatment of cervical spondylosis were included, of which 136 were registered by domestic researchers in 22 provincial-level administrative regions. The top three in terms of registration numbers were Shanghai, Guangdong Province, and Beijing. Additionally, 2 were registered by foreign researchers in Egypt and Malaysia. The main sources of funding were 50 local finances, followed by 26 hospital subsidies and 18 national finances. The intervention research accounted for the largest proportion of research types, with 123 items (89.13%). The research center mainly focused on single center studies (98 projects). Most randomized controlled trials (115 trials) described randomization methods, while a small number of randomized controlled trials (50 trials) indicated blinding. The intervention measures were mostly combined with TCM therapy, and the outcome indicators were mainly efficacy indicators, with fewer safety indicators.Conclusions:At present, clinical trial registrations for TCM treatment of cervical spondylosis are increasing, but issues remain, such as poor study design, uneven distribution, and incomplete information. It is recommended to refine registration details, optimize study protocols, and promote high-quality clinical research.

BACKGROUND:Studies have shown that upregulation of heme oxygenase-1 expression enhances cellular antioxidant and anti-apoptotic abilities.However,the effects of upregulating heme oxygenase-1 expression on the proliferation and differentiation of neural stem cells under oxidative stress conditions remain unclear.OBJECTIVE:To investigate the influence of heme oxygenase-1 overexpression on the survival and differentiation capacity of neural stem cells under oxidative stress conditions.METHODS:(1)Mouse primary neural stem cells were isolated and cultured from newborn Balb/c mice.Immunofluorescence was used to detect the neural stem cell marker Nestin.(2)Lentivirus was used to infect neural stem cells to induce heme oxygenase-1 overexpression.Flow cytometry was used to assess green fluorescent protein fluorescence.Western blot assay was performed to detect the expression levels of heme oxygenase-1.(3)H2O2 was added to the lentivirus-infected neural stem cell culture medium to simulate the oxidative stress microenvironment after spinal cord injury.Effects of heme oxygenase-1 overexpression on neural stem cell proliferation and apoptosis levels were analyzed using cell proliferation assay kits,cell apoptosis assay kits,and TUNEL staining kits.(4)The levels of lipid oxidation markers malondialdehyde,catalase,superoxide dismutase,and glutathione peroxidase were detected using assay kits.(5)Flow cytometry was used to measure intracellular reactive oxygen species levels,and neural stem cell differentiation into astrocytes and neurons.(6)The effect of heme oxygenase-1 overexpression on neuronal axon growth during neural stem cell differentiation was observed under optical and fluorescence microscopes.RESULTS AND CONCLUSION:(1)Mouse neural stem cells exhibited stable morphology,good growth status,and high expression of Nestin as detected by immunofluorescence.(2)Western blot analysis showed that the overexpression of heme oxygenase-1 in the overexpression group was significantly higher than that in the empty carrier control group.Flow cytometry was used to detect the expression of green fluorescent protein in the neural stem cells of the heme oxygenase-1 overexpression group and empty vector control group.(3)Overexpression of heme oxygenase-1 maintained the proliferative activity of neural stem cells and significantly reduced the number of apoptotic cells under oxidative stress conditions.(4)Overexpression of heme oxygenase-1 inhibited lipid peroxidation of neural stem cells under oxidative stress microenvironment,enhanced the expression of enzymes related to maintaining the oxidative-reductive balance,and significantly reduced intracellular reactive oxygen species levels.(5)Overexpression of heme oxygenase-1 promoted the differentiation of neural stem cells into neurons and reduced differentiation into astrocytes.(6)The heme oxygenase-1 overexpression group exhibited longer axons,and more intercellular connections.The above results indicate that overexpression of heme oxygenase-1 can alleviate oxidative damage of H2O2-induced neural stem cells,reduce neural stem cell apoptosis,promote proliferation,and facilitate differentiation of neural stem cells into neurons.

The development of Traditional Chinese Medicine(TCM)medical alliances plays a pivotal role in enhancing grassroots TCM service capabilities and meeting public demand for TCM healthcare.However,challenges persist in establishing these alliances,including insufficient Party leadership at primary TCM institutions and deficiencies in clinical services,talent de-velopment,and emergency care capacity.This study examines innovative Party building approaches in public hospitals within the new era context,analyzing practical cases of alliance development.Our findings demonstrate that integrating Party building into the governance structure of medical alliances not only strengthens Party leadership at primary TCM institutions but also significant-ly promotes TCM service development.Systematic analysis of case hospital practices reveals several key insights.Firstly,strengthening top-level design through Party committee leadership is crucial.Secondly,addressing the most pressing public healthcare concerns with genuine commitment forms the foundation.Thirdly,deep integration of Party building with core medical services represents the essential approach.Lastly,policy-responsive innovation based on consolidated achievements serves as the key driver.

DiGeorge(DGS)syndrome is an autosomal dominant disorder caused by 22q11.2 microdeletions,most patients developed the disease in childhood.22q11.2 deletion syndrome,and the mutation types are dominated by haploid deletion of this gene.We report a young patient with hypoparathyroidism(parathyroidism)induced by DGS syndrome combined with hypocalcemic heart failure.Genetic testing revealed pathogenic copy number variants associated with the clinical phenotype of the subject.About 2 674 kb of deletion variation was detected at q11.21 position on chromosome 22,which contained the TBX1 gene and was a pathogenic mutation.This paper discusses the clinical features,pathogenesis and current treatment of DGS,and emphasizes the importance of early screening,early diagnosis and treatment,and regular follow-up of heart failure,aiming to enhance the awareness of clinicians and geneticists on DGS syndrome.

Objective To investigate the correlation between G protein-coupled receptor family C group 6 member A(GPRC6A)gene polymorphisms and their expression and pulmonary infections in elderly patients with chronic heart failure(CHF).Methods 138 elderly CHF patients admitted to the Xianyang First People's Hospital from January 2021 to January 2024 were selected as the research subjects,and were divided into an infected group(n=42)and an uninfected group(n=96)based on their lung infection status.Polymerase chain reaction(PCR)was used to detect polymorphisms at the rs6901250 and rs1606365 loci of the GPRC6A gene.The allele and genotype frequency distributions of the infected and uninfected groups were compared.Logistic regression modeling was used to analyze the s6901250 and rs1606365 loci under three genetic models(co-dominant,dominant and reces-sive)and lung infections in elderly patients with CHF.Real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression level of GPRC6A gene.The predictive value of the mRNA expression level of the GPRC6A gene for the development of pulmonary infections in elderly patients with CHF was analyzed by applying the receiver operator characteristic(ROC)curve.Results The distribution of genotypes at loci rs6901250 and rs1606365 of the GPRC6A gene in both the infected and uninfected groups of the lungs of elderly CHF patients conformed to the Hardy-Weinberg equilibrium law(χ2=0.199～0.376,all P>0.05),which was representative of the population.Compared with the uninfected group,the frequency of allele A at locus rs6901250(57.14%vs 41.67%)was significantly higher in the infected group,Allele G(54.76%vs.37.50%)and genotype GG(14.06%vs 29.99%)frequencies were significantly higher at locus rs1606365,and the differences were statistically significant(χ2=5.628,7.114,6.849,all P<0.05).At locus rs6901250,in the co-dominant model(GG vs AA)and the dominant model(GA+AA vs GG),the elderly CHF patients with AA genotype the risk of lung infection was higher than that of GG genotype(OR=1.753,1.546,all P<0.05);.rs1606365 locus showed that the risk of lung infection was higher than that of CC genotype in el-derly CHF patients with GG genotype under all three genetic models of co-dominant model(CC vs GG),dominant model(CG+GG vs CC)and recessive model(CG+CC vs GG)(OR=1.833,1.741,0.695,all P<0.05).The mRNA expression level of GPR-C6A gene in the lung-infected group of elderly CHF patients(1.43±0.35)was significantly higher than that in the uninfected group(1.02±0.21),and the difference was statistically significant(t=8.515,P<0.001).The results of the ROC curve analysis showed that the GPRC6A gene expression level predicted lung infection in elderly CHF patients with an AUC value of 0.895,a cut-offvalue of 1.37,and sensitivity and specificity of 85.7%and 66.7%,respectively.Conclusion The AA genotype at the rs6901250 locus and the GG genotype at the rs1606365 locus of the GPRC6A gene increased the risk of developing lung infec-tions in elderly patients with CHF.MRNA expression levels of the GPRC6A gene were elevated in the infected group,and its ex-pression level could be used as a predictive indicator for the development of lung infections in elderly patients with CHF.
