Under the background of the medical model shifting from biomedicine to systems medicine， the traditional Chinese medicine （TCM） concept of "treating different diseases in the same way" demonstrates unique scientific value. From the perspective of systems biology， this study proposes that "treating different diseases in the same way" is essentially "treating the disease with same mechanism in the same way"； that is， different diseases share common pathological links at levels such as neuro-endocrine-immune network homeostasis， inflammatory signaling pathways， or gut microecology. Through the application of the "same formulas" and "same medicinals"， TCM intervenes in these shared network nodes. On this basis， the modern medical value of the "treating different diseases in the same way" concept is elucidated from three dimensions including "network causality" in epistemology， "systemic modulation" in methodology， and "comorbidity management" in practice. It reveals that as a life network regulation concept based on holism， "treating different diseases in the same way" provides novel diagnostic and therapeutic strategies for complex chronic diseases and multimorbidity.

Avian coccidiosis, an acute parasitic disease that mainly harms chicks, is widely prevalent across the world, which poses a serious threat to poultry industry. Because of the single prophylactic formulations, veterinary clinical treatment of coccidiosis mainly relies on chemically synthesized agents, polyether ionophores and Chinese herbal medicines. The introduction of novel anticoccidial drugs is slow for a long period of time, and there is an increasing problem of anticoccidial drug resistance following long-term use, which has become an urgent problem to be solved in poultry industry. This review summarizes the levels of anticoccidial drug resistance across China from 2018 to 2023, and analyzes the resistance to various anticoccidial agents in coccidia. It is indicated that the overall prevalence of anticoccidial drug resistance is high in coccidia, and development of novel anticoccidial agents and products with reduced antibiotics use and alternatives of antibiotics is of an urgent need.

The Inner Canon of Yellow Emperor （《黄帝内经》） constructs its theoretical system under the influence of the holistic， symbolic， and holographic mental models of traditional Chinese medicine （TCM）. It lays the theoretical foundation of TCM and provides a paradigm for TCM theory construction， serving as an original academic gene and theoretical source for the inheritance and innovation of modern TCM. Based on the theoretical paradigms derived from The Inner Canon of Yellow Emperor， the holistic mental model， the symbolic mental model， and the holographic mental model in shaping nature-human medicine theory， imagery-based theory， and fractal theory， this study revealed that TCM theory relies on the cognitive framework of traditional cultural mental models. On this basis， we proposed that the modern TCM mental model should return to its roots while fostering innovation， integrating tradition with modernity by combining macroscopic with microscopic perspectives， scientific with humanistic cognition， as well as evidence-based research with digital and artificial intelligence technologies. Furthermore， with a future-oriented approach， this paper discussed on the strategies for reshaping the modern TCM mental model from three dimensions of TCM diagnosis and treatment， TCM education， and TCM research， which could not only preserve the traditional clinical thinking characteristics of TCM， but also innovate modern TCM practice.

ObjectiveTo investigate the effects of Dihuang Yinzi on the cognitive function in the mouse model of learning and memory impairments induced by scopolamine （SCOP） and explore the treatment mechanism. MethodsA mouse model of learning and memory impairment was induced by intraperitoneal injection of SCOP. Sixty male C57BL/6J mice were randomized into six groups： control （0.9% NaCl， n=10）， model （SCOP 1 mg·kg^-1·d^-1， n=10）， low-， medium-， and high-dose Dihuang Yinzi （SCOP 1 mg·kg^-1·d^-1 + Dihuang Yinzi 5.5， 11.0， and 22.0 g·kg^-1·d^-1， n=10）， and donepezil （SCOP 1 mg·kg^-1·d^-1 + donepezil 0.84 mg·kg^-1·d^-1， n=10）. Mice were administrated with corresponding drugs for 6 weeks. Modeling started in the 4th week， and mice in other groups except the control group were injected with SCOP intraperitoneally 40 min after daily gavage. Behavioral testing began in the 5th week， 30 min after modeling each day. The Morris water maze and novel object recognition tests were carried out to evaluate the spatial learning and memory function of mice. Nissl staining was employed to observe the survival of neurons and Nissl bodies in the hippocampal CA1 region. Western blot was employed to determine the protein levels of silent information regulator 2 （SIRT2）， α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid （AMPA） receptor 1 （GluA1）， protein kinase A （PKA）， cAMP response element-binding protein （CREB）， phosphorylated-CREB （p-CREB）， postsynaptic density protein 95 （PSD95）， growth-associated protein-43 （GAP-43）， and synaptophysin （SYN） in the hippocampus. Immunofluorescence was used to detect the expression of doublecortin （DCX） in the hippocampal dentate gyrus （DG） region. ResultsCompared with the control group， the model group showed impaired learning and memory （P<0.01）， obvious neuronal damage in the hippocampal CA1 region， a reduction in neuron survival （P<0.01）， a decrease in DCX expression in the hippocampal DG region （P<0.01）， down-regulated proteins levels of GluA1， PKA， p-CREB/CREB， PSD95， SYN， and GAP-43 in the hippocampal tissue （P<0.05， P<0.01）， and an up-regulated protein level of SIRT2 （P<0.01）. Compared with the model group， the medium- and high-dose Dihuang Yinzi groups and the donepezil group showed improvements in learning and memory （P<0.05， P<0.01）， while the low-， medium-， and high-dose Dihuang Yinzi groups and the donepezil group had increased neuron survival （P<0.05， P<0.01）. The medium-dose Dihuang Yinzi group and the donepezil group showed increased DCX expression （P<0.05， P<0.01）. The medium- and high-dose Dihuang Yinzi groups and the donepezil group showed up-regulation in the protein levels of GluA1， PKA， p-CREB/CREB， PSD95， SYN， and GAP-43 （P<0.05， P<0.01） and down-regulation in the protein level of SIRT2 （P<0.01）. ConclusionDihuang Yinzi can improve the cognitive function in the mouse model of learning and memory impairments induced by SCOP by inhibiting the upregulation of SIRT2， activating the PKA/CREB signaling pathway， improving synaptic plasticity， and reducing hippocampal neuronal damage.

Objective To investigate how vismodegib(Vis)influences the pathogenesis of basal cell carcinoma(BCC)via a chromatin remodeling factor,bromodomain containing protein 9(BRD9),and to analyze the expression profile of BRD9 in BCC and its relationship with the immune checkpoint,programmed cell death-1 ligand 1(PD-L1)and the Hedgehog(Hh)signaling pathway.Methods ① A UVB-induced BCC model was established in SKH-1 hairless background Ptch1+/-;LacZ reporter mice.Then the mice were treated with Vis,and those without treatment served as control.X-gal staining,immunohistochemistry(IHC)staining,immunofluorescence(IF)assay,and Western blotting were used to assess the expression and localization of BRD9 and PD-L1 in tumor tissues and to evaluate immune-cell infiltration.② In vitro,mouse BCC cell line ASZ001(ASZ cells)were treated with Vis or a BRD9 degrader(dBRD9),and BRD9-overexpressing cells were generated.Cell viability and the protein and mRNA levels of BRD9,PD-L1,Gli1,and cyclin D1(Ccnd1)were measured.ChIP-qPCR was performed to examine BRD9 and H3K27ac enrichment at the PD-L1 promoter,including the promoter-proximal site(P1)and an upstream active segment(P2).Results ① At the tissue level,BRD9 was highly expressed in BCC,and co-localization of BRD9 and PD-L1 was observed within tumor regions,with evident immune-cell infiltration.Vis markedly suppressed UVB-induced BCC formation,reduced the probability of large-volume tumors(by probability-density analysis),decreased the X-gal-positive lesion area(P<0.000 1),down-regulated BRD9(P=0.024 9),and attenuated immune-cell infiltration.② At the cellular level,Vis treatment reduced cell viability and down-regulated BRD9,Gli1,and Ccnd1 in ASZ cells(P<0.000 1).dBRD9 inhibited ASZ cell viability in a dose-dependent manner and decreased PD-L1,Gli1,and Ccnd1(P<0.000 1),whereas its overexpression increased the expression of these molecules(P<0.000 1).In ASZ cells,BRD9 and H3K27ac were enriched at the PD-L1 promoter P1/P2 regions.Treatment with dBRD9 or Vis reduced BRD9 and H3K27ac enrichment at P1/P2 regions(P<0.000 1).Conclusion In BCC,BRD9 maintains chromatin activation at the proximal PD-L1 promoter and modulates Hh/Gli1 signaling,thereby promoting immune evasion.Vis remodels the tumor immune microenvironment by inhibiting the Hh-BRD9-PD-L1 axis.

Objective:To prepare heparin (Hep)-modified gelatin methacryloyl (GelMA) microspheres and to investigate their application in liver-targeted delivery of adipose-derived mesenchymal stem cells (ADSCs).Methods:GelMA microspheres were modified with Hep to obtain GelMA-Hep microspheres. The surface morphology of the GelMA-Hep microspheres was observed by scanning electron microscopy. The changes of carbon atoms, nitrogen atoms and sulfur atoms on the surface of the GelMA-Hep microspheres were detected by X-ray photoelectron spectroscopy. The surface chemical group composition of the GelMA-Hep microspheres was analyzed by Fourier transform infrared spectrometer. The swelling properties of the GelMA-Hep microspheres were detected by water absorption swelling experiment. Human liver HL-7702 cells transfected with lentivirus were co-cultured with GelMA, GelMA-dopamine (GelMA-dop) and GelMA-Hep microspheres. The effects of microspheres on cell proliferation activity were evaluated by cell counting kit-8 method and live/dead cell staining experiment. The adhesion of microspheres to cells was observed by confocal microscopy. The GelMA-Hep microspheres loaded with ADSCs were injected into C57BL/6 mice through the tail vein, and its efficiency of liver-targeted delivery of ADSCs was observed by a small animal in vivo imaging system. The data were compared by independent sample t test or one-way analysis of variance. Results:The GelMA-Hep microspheres were prepared by modifying the GelMA microspheres with Hep. Compared with the GelMA microspheres, the size of the GelMA-Hep microspheres did not change significantly, and the surface did not collapse and showed some crystalline particles. The binding energy of sulfur atoms on the surface of the GelMA-Hep microspheres increased from 166 eV to 168 eV. On the surface of the GelMA-Hep microspheres, the characteristic peaks of sulfonic acid and sulfate groups of Hep were detected at 1 490 cm ?1 and from 1 135 cm ?1 to 1 050 cm ?1, respectively. The swelling rate of the GelMA-dop microspheres was uniform, while the swelling rate of the GelMA microspheres and the GelMA-Hep microsphere was quite different, but the final swelling mass of the three microspheres tended to be consistent at 5 min. After 12, 24, 36 and 48 h of culture, the relative proliferation of cells in the GelMA-Hep group (1.61±0.29, 1.78±0.05, 2.27±0.08, 2.26±0.33) were higher than those in the negative control group (1.00±0.00, 1.28±0.06, 1.39±0.02, 1.41±0.04) (all P<0.05). After 36 h of culture, the relative proliferation of cells in the GelMA-Hep group was higher than that in the GelMA-dop group (1.63±0.21), with significant difference ( P<0.05). Live/dead cell staining experiment showed that after 12 h of cell culture in the GelMA-Hep group, only a few microspheres had cell adhesion; at 24 h, the cells were densely distributed on the surface of the microspheres. After 36 h, the number of cells increased further. At 48 h, live cells were distributed throughout the microspheres. Confocal microscopy showed that after 24 h of culture, cells adhered to the surface of the microspheres in the GelMA-Hep group and showed a stretched morphology. The liver of the GelMA-Hep+ADSCs group showed strong fluorescence at 0.5 h, and the fluorescence brightness continued to 48.0 h. The number of ADSCs reaching the liver was more than that of ADSCs group and GelMA+ADSCs group. Conclusions:GelMA-Hep microspheres were successfully prepared, which can improve the efficiency of liver-targeted delivery of ADSCs.

Breast cancer is one of the most common malignant tumors among women worldwide, with an increasing incidence rate year by year, making it a significant public health concern. With the continuous advancement of tumor biology research, N 6-methyladenosine (m 6A) modification, as an important form of RNA modification, has attracted growing attention. The m 6A modification, the most prevalent RNA modification in eukaryotes, occurs in almost all types of RNA and plays a critical role in the occurrence, progression, and metastasis of breast cancer. It influences cell proliferation, apoptosis, and alterations in the tumor microenvironment, though the specific mechanisms underlying these effects require further in-depth investigation. Moreover, the specific patterns of m 6A modification demonstrate its potential as a novel biomarker for breast cancer, which could provide new directions for early diagnosis and prognosis evaluation.

Objective To compare and analyze the early- to mid-term outcomes of transcatheter aortic valve replacement (TAVR) combined with percutaneous coronary intervention (PCI) versus surgical aortic valve replacement (SAVR) combined with coronary artery bypass grafting (CABG) for the treatment of significant aortic stenosis (AS) and coronary artery disease (CAD). Methods The data of patients with significant AS and CAD who underwent surgical treatment at Central China Fuwai Hospital of Zhengzhou University from January 2018 to July 2023 were collected. These patients were divided into a TAVR+PCI group and a SAVR+CABG group according to the operation method. Propensity score matching (PSM) was used to select patients with close clinical baseline characteristics, and the early- to mid-term outcomes of the two groups were compared. Results A total of 272 patients were enrolled, including 208 males and 64 females, with a mean age of (64.16±8.24) years. There were 47 patients in the TAVR+PCI group and 225 patients in the SAVR+CABG group. After 1 : 1 PSM, 32 pairs were selected. There was no statistical difference in baseline data between the two groups (P>0.05). Compared with the SAVR+CABG group, the TAVR+PCI group had significantly shorter operative time, mechanical ventilation time, ICU stay, postoperative hospital stay, and less intraoperative bleeding, and significantly lower postoperative transfusion and complete revascularization rates (P<0.05). The differences in the rates of postoperative in-hospital death, myocardial infarction, stroke, or other complications between the two groups were not statistically significant (P>0.05), and the differences in the rates of moderate-to-severe perivalvular leakage, death, or readmission in the mid-term follow-up were not statistically significant (P>0.05). Conclusion In patients with significant AS and CAD, the early- and mid-term rates of death and complications are similar between those treated with TAVR+PCI and SAVR+CABG, and TAVR+PCI is a safe alternative to SAVR+CABG.

Objective:To explore the clinical characteristics of adrenal lesions in unilateral primary aldosteronism.Methods:This is a prospective study. Consecutive patients diagnosed with unilateral primary aldosteronism at the First Affiliated Hospital of Chongqing Medical University from December 2023 to November 2024 were included. Inclusion criteria：① Age is 18 to 80 years old；② The laboratory test indicators are in line with the diagnosis of primary aldosteronism；③ The auxiliary examination proved that only one side was involved；④ Patient undergo unilateral total adrenalectomy. The exclusion criteria are as follows：① Complete biochemical remission was not achieved during the 1-6 month follow-up after the surgery；② Postoperative loss to follow-up；③ No surgical specimens were received or the surgical specimens were incomplete，making continuous sectioning impossible. Patients meeting the inclusion criteria were recruited，and their clinical and biochemical data were recorded. The number of adrenal nodules visible on CT scans and the number of macroscopically visible nodules in the postoperative adrenal gross specimens were documented. Hematoxylin-eosin（HE）staining and aldosterone synthase CYP11B2 immunohistochemical staining were performed on the adrenal tissues after the operation. The number of nodules visible under the light microscope and the number of CYP11B2-positive nodules were recorded.Results:A total of 114 cases were included in this study. The age of the patients was（49.86 ± 9.80）years，the body mass index was（25.49 ± 3.40）kg/m2，the preoperative aldosterone level was 352（2012，556）pg/ml，and the direct renin concentration was 1.63（0.50，4.56）μIU/ml. The aldosterone/renin ratio was 224.9（57.1，641.6）（aldosterone concentration unit was pg/ml，renin concentration unit was μIU/ml），the minimum blood potassium concentration was 2.87（2.50，3.40）mmol/L，and the systolic blood pressure was（144.5 ± 19.5）mmHg. Among the 114 patients，105 had adrenal nodules detected by preoperative CT，of whom 2（1.75%）had multiple nodules. Postoperative gross adrenal specimen evaluation and CYP11B2 immunohistochemical staining revealed that 90 out of 114 cases were solitary nodules，2 cases had no nodules，and 22 cases（19.30%）had multiple nodules detected（17 cases had 2 nodules and 5 cases had 3 nodules）. Among them，12 cases（10.53%）presented as grossly visible multinodular lesions，while 10 cases（8.77%）appeared as solitary nodules macroscopically but demonstrated multinodular patterns on immunohistochemical staining. CYP11B2 staining showed that among the 22 patients with multiple nodules，13 had multiple CYP11B2-positive nodules，while the remaining had only one positive nodule. Among the 22 patients with multiple nodules，preoperative CT showed single nodules in 19 cases，hyperplasia in 1 case，and multiple nodules in 2 cases（9.09%）. Among the 12 patients with grossly visible multinodular lesions，preoperative CT showed single nodules in 9 cases，hyperplasia in 1 case，and multiple nodules in 2 cases（16.67%）.Conclusions:Multiple adrenal nodules associated with unilateral primary aldosteronism are relatively common，and are often not detected by preoperative CT examination. Partial adrenalectomy based solely on CT-visible nodules may fail to achieve complete remission of primary aldosteronism. This study provides evidence supporting total adrenalectomy as the preferred surgical approach for unilateral primary aldosteronism.
