ObjectiveTo explore whether the intestinal absorption solution containing Banxia Xiexintang （BXT） can inhibit the invasion and migration of gastric cancer cells by interfering with the stromal cell-derived factor 1 （SDF1）-CXC chemokine receptor 4 （CXCR4） axis in tumor-associated bone marrow mesenchymal stem cells （TA-BMSCs）. MethodsThe intestinal absorption solution containing BXT was prepared， and the optimal intervention concentration and duration for MFC cells were determined through the cell counting kit-8 （CCK-8） assay. A co-culture system was established comprising TA-BMSCs conditioned medium （TA-BMSCs-CM） and gastric cancer MFC cells. The experiment was conducted with a blank control group， a TA-BMSCs-CM group， an SDF1 inhibitor （LY2510924） group， and intervention groups with varying concentrations （55%， 70%， 85%） of the intestinal absorption solution containing BXT. Cell proliferation was assessed by the CCK-8 assay. Horizontal and vertical cell migration were evaluated via scratch and Transwell assays， respectively. Cell invasion was examined by a Transwell assay with Matrigel. Cell apoptosis was detected by flow cytometry. The levels of factors such as SDF1， matrix metalloproteinase-9 （MMP-9）， and vascular endothelial growth factor A （VEGFA）， as well as the protein levels of macrophage migration inhibitory factor （MIF）， CXCR4， VEGFA， and MMP-9， were quantified by ELISA and Western blot， respectively. ResultsThe CCK-8 assay results indicated that compared with the 24 h intervention， the 48 h interventions with all concentrations of the intestinal absorption solution containing BXT increased the inhibition rate on MFC cells （P<0.01）. The half-maximal inhibitory concentration （IC₅₀） of the intestinal absorption solution containing BXT at the time point of 48 h was 68.51%， and subsequent intervention concentrations were selected as 55%， 70%， and 85%. Compared with the TA-BMSCs-CM group， the intestinal absorption solution containing BXT （particularly at concentrations of 70% 85%） suppressed the proliferation， migration， and invasion of MFC cells， promoted the cell apoptosis （P<0.05， P<0.01）， decreased the levels of SDF1， MMP-9， and VEGFA， and downregulated the protein levels of MIF， CXCR4， VEGFA， and MMP-9 （P<0.05， P<0.01）. The inhibitory effects of the intestinal absorption solution containing BXT were comparable to or superior to those of the SDF1 inhibitor （P<0.01）. ConclusionThe intestinal absorption solution containing BXT can inhibit the invasion and migration of gastric cancer cells by interfering with the SDF1-CXCR4 axis in TA-BMSCs. The underlying mechanism may involve the regulation of the MIF/SDF1/CXCR4 signaling pathway and its downstream effector molecules.

ObjectiveTo observe how Banxia Xiexintang affects programmed cell death 1 ligand 1 （PD-L1） expression induced by exosomes derived from gastric cancer cells in bone marrow mesenchymal stem cells （BMSCs） through the protein kinase B （Akt）/c-myelocytomatosis oncogene （c-Myc） signaling axis， and its effects on the migration of BMSCs and gastric cancer cells. MethodsExosomes were isolated from human gastric cancer NCI-N87 cells and identified by transmission electron microscopy and Western blot. Rat BMSCs were passaged and identified by immunofluorescence staining. A Transwell chamber was used to create a non-contact co-culture system for NCI-N87 exosomes and BMSCs. The experiment was designed with normal， model， Banxia Xiexintang （10% serum containing Banxia Xiexintang）， PD-L1 monoclonal antibody （10% blank serum containing PD-L1 antibody）， and combination （10% serum containing Banxia Xiexintang and 10% blank serum containing PD-L1 antibody） groups. The suspension of BMSCs was added to the upper chamber of each group， with the normal group receiving serum culture medium without exosomes in the lower chamber， and the model group receiving NCI-N87 exosomes. The Banxia Xiexintang group， PD-L1 monoclonal antibody group， and combination group received 10% serum containing Banxia Xiexintang， 10% blank serum containing PD-L1 monoclonal antibody， and 10% serum containing Banxia Xiexintang and 10% blank serum containing PD-L1 antibody， respectively， in the upper chamber. After 96 h， BMSCs from the upper chamber were collected， and the protein levels of p-Akt， Akt， c-Myc， and PD-L1， as well as the mRNA levels of Akt， c-Myc， and PD-L1， were determined by Western blot and Real-time PCR， respectively. The migration of BMSCs and NCI-N87 was assessed by the Transwell method. ResultsCompared with the normal group， the model group showed increases in protein levels of p-Akt， c-Myc， and PD-L1， as well as mRNA levels of c-Myc and PD-L1 （P<0.05， P<0.01）， and no significant change in the protein and mRNA levels of Akt. Compared with the model group， the Banxia Xiexintang group， PD-L1 monoclonal antibody group， and combination group showed decreases in protein levels of p-Akt， c-Myc， and PD-L1 （P<0.01）. In addition， they had significant effects on the protein and mRNA levels of Akt. The combination group showed greater reductions in the protein and mRNA levels of c-Myc and PD-L1 than the Banxia Xiexintang group and PD-L1 monoclonal antibody group （P<0.05）. Compared with the normal group， the model group showed increases in the number of migrating NCI-N87 and BMSCs （P<0.05， P<0.01）. Compared with the model group， the Banxia Xiexintang group， PD-L1 monoclonal antibody group， and combination group showed decreases in the number of migrating NCI-N87 and BMSCs （P<0.05， P<0.01）， with the combination group showing greater reductions in the number of migrating NCI-N87 and BMSCs than the Banxia Xiexintang group and PD-L1 monoclonal antibody group （P<0.01）. ConclusionBanxia Xiexintang can lower the PD-L1 expression induced by gastric cancer cell-derived exosomes in BMSCs induced and inhibit the migration of BMSCs and gastric cancer cells. Moreover， it has a synergistic effect when being used together with PD-L1， possibly related to the regulation of the Akt/c-Myc signaling axis.

Alzheimer's disease(AD)is the leading cause of dementia,and no effective treatment has been devel-oped for it thus far.Recently,the use of natural compounds in the treatment of neurodegenerative diseases has garnered significant attention owing to their minimal adverse reactions.Accordingly,the potential therapeutic effect of pterostilbene(PTS)on AD has been demonstrated in multiple in vivo and in vitro experiments.In this study,we systematically reviewed and summarized the results of these studies investigating the use of PTS for treating AD.Analysis of the literature revealed that PTS may play a role in AD treatment through various mechanisms,including anti-oxidative damage,anti-neuroinflammation,anti-apoptosis,cholinesterase activity inhibition,attenuation of β-amyloid deposi-tion,and tau protein hyperphosphorylation.Moreover,PTS interferes with the progression of AD by regulating the activities of peroxisome proliferator-activated receptor alpha(PPAR-α),monoamine oxi-dase B(MAO-B),silent information regulator sirtuin 1(SIRT1),and phosphodiesterase 4A(PDE4A).Furthermore,to further elucidate the potential therapeutic mechanisms of PTS in AD,we employed network pharmacology and molecular docking technology to perform molecular docking of related proteins,and the obtained binding energies ranged from-2.83 to-5.14 kj/mol,indicating that these proteins exhibit good binding ability with PTS.Network pharmacology analysis revealed multiple po-tential mechanisms of action for PTS in AD.In summary,by systematically collating and summarizing the relevant studies on the role of PTS in treatment of AD,it is anticipated that this will serve as a reference for the precise targeted prevention and treatment of AD,either using PTS or other developed drug interventions.

B and T lymphocyte attenuator (BTLA) is an inhibitory immune checkpoint, which typically interacts with herpesvirus entry mediator (HVEM) and plays a crucial role in regulating immune balance. BTLA interacts with its ligand HVEM in a cis manner on the surface of the same immune cell to maintain immune tolerance, while trans interactions on the surface of different immune cells mediate immunosuppressive effects. Dysregulation of the BTLA/HVEM axis can impair the functions of immune cells, particularly T lymphocytes, promoting immune escape of tumor cells and ultimately leading to tumor progression. Researchers have found that BTLA and HVEM are abnormally expressed in various tumors and are associated with prognosis, suggesting that they may be potential targets for tumor immunotherapy. This review summarizes the molecular structures of BTLA and HVEM, immunomodulatory mechanisms, recent advances in hematologic malignancies, potential inhibitors of BTLA/HVEM interaction, and their applications in immunotherapy for hematologic malignancies.

Objective To investigate the therapeutic effects and mechanisms of Xuefu Zhuyu Mixture(XFZY)in rats with coronary heart disease(CHD).Methods A CHD rat model was established.Successfully modeled rats were randomly divided into five groups(n=12 each):model group,Lipitor group,low-dose XFZY group(7.02 g·kg-1·d-1),high-dose XFZY group(14.04 g·kg-1·d-1),and high-dose XFZY+RS09[Toll-like receptor 4(TLR4)agonist]group(14.04 g·kg-1·d-1 XFZY+intraperitoneal RS09),with an additional normal control group(n=12).After treatment,following treatment completion,all rats underwent echocardiography to assess left ventricular end-diastolic diameter(LVDd),end-systolic diameter(LVDs),ejection fraction(LVEF),and fractional shortening(FS).Myocardial histopathology and vascular remodeling indices were evaluated via hematoxylin-eosin(HE)staining,while myocardial fibrosis was examined using Masson's trichrome staining.Enzyme-linked immunosorbent assay(ELISA)was employed to quantify inflammatory cytokine levels[tumor necrosis factorα(TNF-α),interleukin(IL)-1β,and IL-6]in myocardial tissues.Immunohistochemical analysis determined protein expression of B-cell lymphoma-2(Bc12)and Caspase 3 in myocardial tissues.Western Blot was performed to measure myocardial protein expression levels of TLR4,phosphatidylinositol 3-kinase(PI3K),phosphorylated protein kinase B(p-AKT),total AKT,phosphorylated mammalian target of rapamycin(p-mTOR),and total mTOR.Results Compared with the normal group,rats in the model group exhibited severe myocardial tissue damage,along with significantly elevated collagen volume fraction,LVDs,LVDd,myocardial levels of IL-6,TNF-α and IL-1β,cardiomyocyte apoptosis ratio,aortic media thickness,and protein expression of Caspase 3,TLR4,PI3K,p-AKT/AKT and p-mTOR/mTOR in myocardial tissue(P＜0.05).Conversely,LVEF,FS,aortic luminal diameter,and Bcl-2 protein content were significantly reduced,the difference being statistically significant(P＜0.05).Compared to the model group,both low-and high-dose XFZY groups as well as the Lipitor group demonstrated attenuated myocardial lesions,with significant reductions in collagen volume fraction,LVDs,LVDd,myocardial IL-6,TNF-α,IL-1β levels,cardiomyocyte apoptosis ratio,aortic media thickness,and protein expression of Caspase 3,TLR4,PI3K,p-AKT/AKT and p-mTOR/mTOR(P＜0.05).Concurrently,LVEF,FS,aortic luminal diameter,and Bcl-2 protein content were significantly increased,the difference being statistically significant(P＜0.05).No statistically significant differences were observed between the high-dose XFZY group and the Lipitor group for any aforementioned parameters(P＞0.05).However,rats treated with high-dose XFZY plus RS09 showed aggravated myocardial injury with manifested interstitial fibrosis,alongside significantly intensified inflammatory response,cardiomyocyte apoptosis,and vascular remodeling compared to the high-dose XFZY alone group(all P＜0.05).Conclusion XFZY alleviates CHD symptoms by suppressing TLR4/PI3K/AKT/mTOR pathway activation,thereby reducing myocardial inflammation,fibrosis,apoptosis,and vascular remodeling.

Objective To investigate the effects of acupoint application at Tianshu(ST25)combined with kidney-warming and spleen-invigorating therapy on clinical efficacy,intestinal function,and the expressions of Toll-like receptor 4(TLR4)and nuclear factor kappa-B(NF-κB)in patients with ulcerative colitis(UC).Methods A total of 100 UC patients with depletion and deficiency of spleen-kidney complicated with internal accumulation of pathogenic dampness syndrome,treated in the Department of Proctology,Shanghai Municipal Hospital of Traditional Chinese Medicine Affilated to Shanghai University of Traditional Chinese Medicine from June 2022 to June 2024,were selected and randomly divided into four groups(Groups A,B,C,D)using a random number table method,with 25 patients in each group.Group A received standard mesalazine treatment.Group B received Kidney-Warming and Spleen-Invigorating Formula(composed of Psoraleae Fructus,Myristicae Semen,Euodiae Fructus,Schisandrae Chinensis Fructus,Codonopsis Radix,Poria,Atractylodis Macrocephalae Rhizoma,etc.)combined with standard mesalazine treatment.Group C received acupoint application at Tianshu(the medicinal paste for application composed of Caryophylli Flos,Cinnamomi Cortex,Atractylodis Macrocephalae Rhizoma,Euodiae Fructus,Coptidis Rhizoma,etc.)combined with standard mesalazine treatment.Group D received Kidney-Warming and Spleen-Invigorating Formula+acupoint application at Tianshu+standard mesalazine treatment.All groups were treated continuously for 12 weeks.The time for disappearance of clinical symptoms was compared among the four groups.Serum immune cytokines[β-defensin-1,total immunoglobulin A(IgA),interleukin-6(IL-6),tumor necrosis factor-alpha(TNF-α)],peripheral blood levels of TLR4 and NF-κB,protein expression levels of TLR4 mRNA and NF-κB p65 mRNA in intestinal mucosal tissue,and changes in intestinal microbiota were observed before and after treatment.The clinical efficacy of the four groups was evaluated.Results(1)Compared to the other three groups,Group D had the shortest time for disappearance of clinical symptoms such as abdominal pain,diarrhea,mucopurulent bloody stools,and tenesmus(P＜0.05).The time for disappearance of various clinical symptoms in Groups B and C was similar(P＞0.05)but was shorter than that in Group A(P＜0.05).(2)After treatment,the serum levels of β-defensin-1,IgA,IL-6,and TNF-α in all four groups were significantly lower than those before treatment(P＜0.05).Post-treatment intergroup comparisons showed statistically significant differences(P＜0.01),with Group D exhibiting the greatest reduction,significantly lower than the other three groups(P＜0.05).The levels in Groups B and C were similar(P＞0.05)but were lower than those in Group A(P＜0.05).(3)After treatment,the peripheral blood levels of TLR4 and NF-κB,and the protein expression levels of TLR4 mRNA and NF-κB p65 mRNA in intestinal mucosal tissue showed a decreasing trend in all four groups(P＜0.05).Post-treatment intergroup comparison results were statistically significant(P＜0.01),with Group D showing the greatest reduction,significantly lower than the other three groups(P＜0.05).All above levels in Groups B and C were similar(P＞0.05)but were lower than those in Group A(P＜0.05).(4)After treatment,the relative contents of Bifidobacterium and Lactobacillus increased(P＜0.05),while those of Saccharomyces and Clostridium decreased(P＜0.05)in Groups B,C,and D.Post-treatment intergroup comparison results were statistically significant(P＜0.01).Group D showed a significant increase in Bifidobacterium and Lactobacillus and a significant decrease in Saccharomyces and Clostridium,with the magnitude of change significantly greater than that in the other three groups(P＜0.05).The quantities of these bacteria in Groups B and C were similar(P＞0.05),but the improvement was significantly greater than that in Group A(P＜0.05).(5)After 12 weeks of treatment,Group D had the highest total effective rate at 100.00％(25/25).The total effective rates of Groups B and C were similar,both at 84.00％(21/25),but were higher than that of Group A(56.00％,14/25).The intergroup difference was statistically significant(x2=16.310,P＜0.01).Conclusion The comprehensive treatment regimen of acupoint application at Tianshu combined with Kidney-Warming and Spleen-Invigorating Formula,on the basis of standard mesalazine treatment,has a positive impact on UC patients with depletion and deficiency of spleen-kidney complicated with internal accumulation of pathogenic dampness syndrome.This treatment method can effectively improve clinical symptoms,regulate β-defensin-1 and IgA levels,enhance immune defense function,downregulate the expression levels of TLR4 and NF-κB,and alleviate inflammatory response.Compared to monotherapies,it is more effective on improving treatment outcomes.

OBJECTIVE: To investigate the effectiveness of using 3 hollow compression screws combined with 1 screw off-axis fixation under the guidance of three-dimensional (3D) printed guide plate with mortise-tenon joint structure (mortise-tenon joint plate) for the treatment of Pauwels type Ⅲ femoral neck fractures. METHODS: A clinical data of 78 patients with Pauwels type Ⅲ femoral neck fractures, who were admitted between August 2022 and August 2023 and met the selection criteria, was retrospectively analyzed. The operations were assisted with mortise-tenon joint plates in 26 cases (mortise-tenon joint plate group) and traditional guide plates in 28 cases (traditional plate group), and without guide plates in 24 cases (control group). There was no significant difference in the baseline data of gender, age, body mass index, cause of injury, and fracture side between groups ( P>0.05). The operation time, intraoperative blood loss, frequency of intraoperative fluoroscopy, incision length, incidence of postoperative deep vein thrombosis of lower extremity, pain visual analogue scale (VAS) score at 1 week after operation, and Harris score of hip joint at 3 months after operation were recorded and compared. X-ray re-examination was taken to check the quality of fracture reduction, fracture healing, and the shortening length of the femoral neck at 3 months after operation, and the incidences of internal fixation failure and osteonecrosis of the femoral head during operation. RESULTS: Compared with the control group, the operation time, intraoperative blood loss, and frequency of intraoperative fluoroscopy reduced in the two plate groups, and the quality of fracture reduction was better, but the incision was longer, and the differences were significant ( P<0.05). The operation time and intraoperative blood loss were significantly higher in the traditional plate group than in the mortise-tenon joint plate group ( P<0.05), the incision was significantly longer ( P<0.05); and the difference in fracture reduction quality and the frequency of intraoperative fluoroscopy was not significant between two plate groups ( P>0.05). There was 1 case of deep vein thrombosis of lower extremity in the traditional plate group and 1 case in the control group, while there was no thrombosis in the mortise-tenon joint plate group. There was no significant difference in the incidence between groups ( P>0.05). All patients were followed up 12-15 months (mean, 13 months). There was no significant difference in VAS score at 1 week and Harris score at 3 months between groups ( P>0.05). Compared with the control group, the fracture healing time and the length of femoral neck shortening at 3 months after operation were significantly shorter in the two plate groups ( P<0.05). There was no significant difference between the two plate groups ( P>0.05). There was no significant difference in the incidences of non-union fractures, osteonecrosis of the femoral head, or internal fixation failure between groups ( P>0.05). CONCLUSION For Pauwels type Ⅲ femoral neck fractures, the use of 3D printed guide plate assisted reduction and fixation can shorten the fracture healing time, reduce the incidence of postoperative complications, and be more conducive to the early functional exercise of the affected limb. Compared with the traditional guide plate, the mortise-tenon joint plate can reduce the intraoperative bleeding and shorten the operation time.
