Objective:To observe the effects of warming triple needling plus Chinese medication on inflammatory responses and daily functioning ability in patients with knee osteoarthritis(KOA)due to wind-cold-dampness Bi-impediment. Methods:A total of 101 patients with KOA due to wind-cold-dampness Bi-impediment were divided into an acupuncture-medication group and a Chinese medication group using the random number table method.Fifty cases in the Chinese medication group took oral Fang Feng Xi Bi Tang for treatment,and 51 cases in the acupuncture-medication group received additional warming triple needling therapy.The symptom score of traditional Chinese medicine(TCM),inflammatory factor levels,and motor function of the knee joint were compared before and after treatment.The clinical efficacy was also compared between the two groups after treatment. Results:Three cases in the acupuncture-medication group and 2 cases in the Chinese medication group dropped out during the study,and the two groups each had 48 cases being included in statistical analysis ultimately.The total effective rate was 95.8%in the acupuncture-medication group,higher than 79.2%in the Chinese medication group,and the between-group difference was statistically significant(P<0.05).After treatment,the TCM symptom score dropped in both groups(P<0.05)and was lower in the acupuncture-medication group than in the Chinese medication group(P<0.05).The levels of interleukin(IL)-6,tumor necrosis factor(TNF)-α,and IL-1β dropped after the intervention in both groups(P<0.05)and were lower in the acupuncture-medication group than in the Chinese medication group(P<0.05).The scores of knee pain intensity,knee joint stiffness,and diurnal functioning decreased after treatment in the two groups(P<0.05)and were lower in the acupuncture-medication group than in the Chinese medication group(P<0.05). Conclusion:Warming triple needling plus Fang Feng Xi Bi Tang can reduce inflammatory responses,improve daily functioning ability,and enhance the quality of life in patients with KOA due to wind-cold-dampness Bi-impediment.

"Tendency of disease" is an important concept in the theory of traditional Chinese medicine （TCM）. It was born out of and rooted in the thinking of "conducting by tendency" of ancient Chinese philosophy， meaning that the development and change of humans and nature have their own inevitable laws and dynamic tendencies. Based on the concept of holism and constant motion， the basic definition of "tendency"， the origin of the idea， the influence factors and related concepts were analysed， to grasp the overall connection in the dynamic changes in space and time， and to find a scientific and comprehensive objective law of development. The "tendency" was regarded as dynamic forces in the complex system， when yin and yang harmonized， called normal tendency； when fail to keep normal， called disease tendency； the season have sequential tendency， the earth has geographical tendency， people have body tendency， medications have medical tendency， and pulse has pulse tendency. Then the "eight methods of treating tendency" were summed up as observing tendency， evaluating tendency， waiting for tendency， accumulating tendency， favoring tendency， counteracting tendency， preventing tendency， and borrowing tendency， and condenses the methodo-logical thinking of "treatment according to disease tendency"， with a view to re-understanding the internal logic of TCM diagnosis and treatment， and providing metaphysical contemplation and exploration for the construction of a new paradigm of TCM syndrome differentiation and treatment.

As a potential vectored vaccine,Newcastle disease virus(NDV)has been subject to various studies for vaccine development,while relatively little research has outlined the immunomodulatory effect of the virus in antigen presentation.To elucidate the key inhibitory factor in regulating the interaction of infected dendritic cells(DCs)and T cells,DCs were pretreated with the NDV vaccine strain LaSota as an inhibitor and stimulated with lipopolysaccharide(LPS)for further detection by enzyme-linked immunosorbent assay(ELISA),flow cytometry,immunoblotting,and quantitative real-time polymerase chain reaction(qRT-PCR).The results revealed that NDV infection resulted in the inhibition of interleukin(IL)-12p40 in DCs through a p38 mitogen-activated protein kinase(MAPK)-dependent manner,thus inhibiting the synthesis of IL-12p70,leading to the reduction in T cell proliferation and the secretion of interferon-γ(IFN-γ),tumor necrosis factor-α(TNF-α),and IL-6 induced by DCs.Consequently,downregulated cytokines accelerated the infection and viral transmission from DCs to T cells.Furthermore,several other strains of NDV also exhibited inhibitory activity.The current study reveals that NDV can modulate the intensity of the innate?adaptive immune cell crosstalk critically toward viral invasion improvement,highlighting a novel mechanism of virus-induced immunosuppression and providing new perspectives on the improvement of NDV-vectored vaccine.

AIM:To explore the correlation between trimethylamine-N-oxide(TMAO)and type 2 diabetic kidney disease(DKD),and to provide new ideas for the early clinical diagnosis of DKD.METHODS:A total 246 patients with type 2 diabetes mellitus(T2DM)ad-mitted to the Department of Endocrinology of the First Hospital of Lanzhou University from January 1,2020 to May 31,2020 were divided into diabetic kidney disease group(DKD group)and simple diabetes mellitus group(NDKD group).According to urinary albumin/creatinine ratio(UACR),the patients were divided into A1,A2 and A3 subgroups.According to the estimated glomerular filtration rate(eGFR),the patients were divided into G1,G2,G3 and G4-5 sub-groups.According to the Kidney Disease:Improving Global Outcomes(KDIGO)guidelines,the risk of progression of DKD was assessed(low,medium,high or very high risk).General clinical data and laboratory indicators were collected.TMAO level was measured by euzymelinked immunosorbent assay.SPSS 25.0 software was used for statistical analysis.RESULTS:In T2DM patients,TMAO level was positively correlated with UACR(r=0.515,P<0.01)and negatively correlated with eGFR(r=-0.409,P<0.01).TMAO is an indepen-dent risk factor for the onset and progression of DKD.In diagnostic model,the AUROC was 0.745 with op-timal cut-off value was 5.37μmol/L.CONCLUSION:TMAO is closely related to the occurrence and de-velopment of DKD,and it has certain clinical predictive value for DKD.Therefore,TMAO may become a po-tential target for the early diagnosis and treatment of DKD.

Objective:To explore the impact of self-disclosure on demoralization syndrome in patients with permanent enterostomy for colorectal cancer, so as to provide reference for clinical nursing interventions for those patients.Methods:From January to May 2023, convenience sampling was used to select 207 patients with permanent enterostomy for colocrctal cancer of the Wound Ostomy Clinic of Laoshan Campus of the Affiliated Hospital of Qingdao University as the research subjects. A survey was conducted on patients using the General Information Questionnaire, Distress Disclosure Index, Social Support Rating Scale, and the Demoralization Scale Mandarin Version.Results:Among 207 patients with permanent enterostomy for colorectal cancer, the scores of self-disclosure, social support, and demoralization syndrome were 35.00 (26.00, 47.00) , 32.00 (26.00, 39.00) , and 35.00 (23.00, 47.00) , respectively. A total of 128 patients (61.8%) were in moderate demoralization, and 37 patients (17.9%) were in severe demoralization. Multiple linear regression analysis showed that place of residence, self-care of stoma, self-disclosure, and social support were the influencing factors for demoralization syndrome in patients with permanent enterostomy for colorectal cancer ( P<0.05) . Conclusions:Patients with permanent enterostomy for colorectal cancer have a high overall score of demoralization syndrome, and a high proportion of patients with moderate to severe demoralization. Medical and nursing staff should focus on patients in remote rural areas and those with poor self-care abilities to stomas, develop targeted intervention measures to improve patients' negative emotions, enhance their self-disclosure, and pay attention to strengthening social support to relieve their demoralization syndrome, thereby improving their quality of life.

Objective To create a mouse model of colorectal polyps with Apc-Kras-Cre gene mutations using the tamoxifen induction method.Methods Mice with Apc-Kras-Cre mutations were divided into four groups and injected intraperitoneally with different concentrations and dosages of tamoxifen for different durations,with group 1 injected with low dosage tamoxifen(5 mg/kg)for 1 day,group 2 injected with low dosage tamoxifen(5 mg/kg)for 3 days,group 3 injected with high dosage tamoxifen(50 mg/kg)for 1 day,group 4 injected with high dosage tamoxifen(50 mg/kg)for 3 days.C57BL/6J mice were used as a healthy control group and survival and changes in body weight were observed.All mice were euthanized 4 weeks post-tamoxifen induction and the colon length and number and size of intestinal polyps were observed.Histological changes in the intestinal tissue and polyps were detected by hematoxylin and eosin staining.Results The survival rate of male mice was higher(P＜0.001)and the morbidity rate of male mice was lower compared with female mice(P＜0.05).The survival rate differed significantly among the four groups(P＜0.01).All groups showed significant changes in body weight compared with the healthy control group(P＜0.001).There were also significant differences in weight changes between tamoxifen-induced groups 1 and 2,between groups 2 and 3,and between groups 1 and 4(P＜0.001,P＜0.01,P＜0.05,respectively).There were no significant differences in colon length between any treated group and the healthy control group(P＞0.05),but colon length did differ between tamoxifen-induced groups 1 and 3(P＜0.05).Polyp size varied in each group of tamoxifen-treated mice,with most polyps occuring at the distal end of the colon,while mice in groups 3 and 4 had more and larger polyps.Histopathological examination showed intestinal polyps with uneven and misaligned glandular and epithelial arrangements,a loosely-packed intestinal mucosal barrier,and irregularly-distributed crypts in tamoxifen-induced mice compared with the healthy control group,while mice in tamoxifen-induced groups 3 and 4 showed signs of inflammation and mice in group 4 showed necrosis of cells in some regions.Conclusions Tamoxifen-induced Apc-Kras-Cre model mice were successfully established,with the group 3 induction method being the most suitable.

The anti-tumor effect of anti-PD-1 antibody has long been shown to be strongly related to the tumor immune microenvironment (TIME). This study aimed to mechanistically assess whether Chang Wei Qing (CWQ) Decoction can enhance the anti-tumor effect of PD-1 inhibitor therapy. PD-1 inhibitor therapy showed the significant anti-tumor effect in patients with mismatch repair-deficient/microsatellite instability-high (dMMR/MSI-H) colorectal cancer (CRC), rather than those with mismatch repair-proficient/microsatellite stable (pMMR/MSS) CRC. Hence, immunofluorescence double-label staining was utilized to explore the difference in the TIME between dMMR/MSI-H and pMMR/MSS CRC patients. Flow cytometry was used to analyze T-lymphocytes in tumors from mice. Western blot was used to measure the expression of PD-L1 protein in mouse tumors. The intestinal mucosal barrier of mice was evaluated by hematoxylin-eosin staining and immunohistochemistry. 16S rRNA-gene sequencing was used to examine the structure of the gut microbiota in mice. Subsequently, Spearmanapos;s correlation analysis was used to analyze the relationship between the gut microbiota and tumor-infiltrating T-lymphocytes. The results showed that dMMR/MSI-H CRC patients had more CD8⁺T cells and higher expression of PD-1 and PD-L1 proteins. In vivo, CWQ enhanced the anti-tumor effect of anti-PD-1 antibody and increased the infiltration of CD8⁺ and PD-1⁺CD8⁺ T cells in tumors. Additionally, the combination of CWQ with anti-PD-1 antibody resulted in lower inflammation in the intestinal mucosa than that induced by anti-PD-1 antibody alone. CWQ and anti-PD-1 antibody co-treatment upregulated PD-L1 protein and reduced the abundance of Bacteroides in the gut microbiota but increased the abundance of Akkermansia,Firmicutes, andActinobacteria. Additionally, the proportion of infiltrated CD8⁺PD-1⁺, CD8⁺, and CD3⁺ T cells were found to be positively correlated with the abundance of Akkermansia. Accordingly, CWQ may modulate the TIME by modifying the gut microbiota and consequently enhance the anti-tumor effect of PD-1 inhibitor therapy.

Platycodon grandiflorum (Jacq.) A. DC. is a famous medicinal plant commonly used in East Asia. Triterpene saponins isolated from P. grandiflorum are the main biologically active compounds, among which polygalacin D (PGD) has been reported to be an anti-tumor agent. However, its anti-tumor mechanism against hepatocellular carcinoma is unknown. This study aimed to explore the inhibitory effect of PGD in hepatocellular carcinoma cells and related mechanisms of action. We found that PGD exerted significant inhibitory effect on hepatocellular carcinoma cells through apoptosis and autophagy. Analysis of the expression of apoptosis-related proteins and autophagy-related proteins revealed that this phenomenon was attributed to the mitochondrial apoptosis and mitophagy pathways. Subsequently, using specific inhibitors, we found that apoptosis and autophagy had mutually reinforcing effects. In addition, further analysis of autophagy showed that PGD induced mitophagy by increasing BCL2 interacting protein 3 like (BNIP3L) levels.In vivo experiments demonstrated that PGD significantly inhibited tumor growth and increased the levels of apoptosis and autophagy in tumors. Overall, our findings showed that PGD induced cell death of hepatocellular carcinoma cells primarily through mitochondrial apoptosis and mitophagy pathways. Therefore, PGD can be used as an apoptosis and autophagy agonist in the research and development of antitumor agents.
