Objective To develop and validate a model to predict the risk of radiation-induced lung injury (RILI) and assess its clinical feasibility. Methods Clinical data from 125 patients with non-small cell lung cancer (NSCLC) were included in the study. The patients were divided into training group (88 cases) and validation group (38 cases). Key predictive factors were identified using univariate and multivariate logistic regression analyses combined with least absolute shrinkage and selection operator (LASSO) regression. A predictive model was constructed and evaluated using a nomogram, receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis. Results The key variables identified by the model were tumor volume (P = 0.017), Eastern Cooperative Oncology Group performance status score (P = 0.035), 95% of the minimum dose to the target volume (P = 0.028), percentage of bilateral lung volume receiving 20 Gy of radiation (P < 0.001), and neutrophil-to-lymphocyte ratio (P = 0.021). The ROC curve showed that the areas under the curve (AUC) for the model in the training and validation groups were 0.987 and 0.992, respectively, indicating good predictive ability. The calibration curve and decision curve further confirmed the accuracy and clinical practicability of the model. Conclusion The predictive model proposed in this study can accurately assess the risk of developing RILI in patients with NSCLC who have undergone radiotherapy, demonstrating its potential value in clinical practice.

A virus was successfully isolated from a sick cat exhibiting clinical signs such as oral mu-cosal ulceration,nasal mucosal redness,and increased nasal secretions utilizing F81 cells.Through a comprehensive analysis as such PCR amplication,sequencing,morphology,serology,and animal re-gression tests,the virus was identified as a feline calicivirus and named FCV-BJ,an inactivated vac-cine was developed from this isolated strain its safety and efficacy were assessed.The results re-vealed that the isolated FCV-BJ strain exhibited characteristic serological and morphological fea-tures consistent with caliciviruses.Furthermore,inoculation of cats with the FCV-BJ demonstrated the strain is highly virulent and the cats manifested the clinical signs of feline calicivirus infection.For the vaccination trial,domestic cats were immunized with inactivated fifth-generation virus cell culture at varying dilutions,followed by a booster immunization after 21 days.Fourteen days after the challenge with the virus,cats immunized with 107.0 TCID50/mL or higher remained largely healthy,while all cats in the control group developed clinical signs of FCV.These findings suggest that the inactivated vaccine derived from the FCV-BJ isolate exhibits strong immunogenicity and protective efficacy at a minimum immunization dose of 107.0 TCID50/mL.This strain holds promise as a candidate for vaccine production,providing a valuable reference and foundation for future re-search and development of feline calicivirus vaccines.

Objective:To explore the relationship between relapse tendency and psychological craving in fe-male methamphetamine(MA)-dependent young adults,focusing on the roles of self-control and future time per-spective.Methods:A total of 340 MA-dependent young adults from two women's compulsory isolation drug reha-bilitation centers in Sichuan Province were included.Participants were assessed with the Relapse Tendency Ques-tionnaire(RTQ),Obsessive Compulsive Drug Use Scale(OCDUS),Drug Abuser Self-Control Ability Question-naire(DASAQ)and General Future Time Perspective Scale(GFTPQ).The moderated mediation model was ana-lyzed by using the SPSS macro program PROCESS(version4.2).Results:The RTQ scores were positively correla-ted with the OCDUS scores(r=0.45,P＜0.001).The DASAQ scores partially mediated the relationship between the scores of OCDUS and RTQ,accounted for 37.91％of the total effect.The GFTP scores moderated the relation-ship between the scores of the OCDUS,DASAQ and RTQ(β=-0.18,0.19,P＜0.001).Conclusion:The influ-ence of psychological craving on relapse tendency in female MA-dependent young adults exhibits a moderated me-diating effect,suggesting the potential of enhancing self-control and future time perspective for preventing relapse and improving detoxification efficiency.

Heart failure(HF)is a highly morbid syndrome that seriously affects the physical and mental health of patients and generates an enormous socio-economic burden.In addition to cardiac myocyte oxidative stress and apoptosis,which are considered mechanisms for the development of HF,alterations in cardiac energy metabolism and pathological autophagy also contribute to cardiac abnormalities and ultimately HF.Silent information regulator 1(Sirt1)and adenosine monophosphate-activated protein kinase(AMPK)are nicotinamide adenine dinucleotide(NAD+)-dependent deacetylases and phosphorylated kinases,respectively.They play similar roles in regulating some pathological processes of the heart through regulating targets such as peroxisome proliferator-activated receptor γ coactivator 1α(PGC-1α),protein 38 mitogen-activated protein kinase(p38 MAPK),peroxisome proliferator-activated receptors(PPARs),and mammalian target of rapamycin(mTOR).We summarized the synergistic effects of Sirt1 and AMPK in the heart,and listed the traditional Chinese medicine(TCM)that exhibit cardioprotective properties by modulating the Sirt1/AMPK pathway,to provide a basis for the development of Sirt1/AMPK activators or inhibitors for the treatment of HF and other cardiovascular diseases(CVDs).

Objective To explore the mechanism of Yanggan Anhun Decoction in the treatment of insomnia with liver failing in storing soul type based on network pharmacological methods;To perform animal model validation.Methods The drug components and targets of Yanggan Anhun Decoction were retrieved from TCMSP and BATMAN-TCM databases,and the targets of insomnia with liver failure store soul type were retrieved from GeneCards,NCBI and DisGeNET databases.By constructing a protein-protein interaction(PPI)network and analyzing GO and KEGG pathway enrichment,the signaling pathway of Yanggan Anxin Decoction in treating insomnia with liver failing in storing soul type was determined,and molecular docking was performed between the main active components and core targets.24 SD rats were randomly divided into normal group,model group,TCM group and Western medicine group,with 6 rats in each group.The insomnia model rats with liver failing in storing soul type were constructed by compound multi factor stimulation method,and were given drugs for 14 days.The cognitive memory ability of rats were detected by Morris water maze test;Nissl staining was used to observe the morphology and number of Nissl bodies in the hypothalamus of rats;serum IL-6 and TNF-α contents were detected by ELISA;IL-6 and TNF-α in hypothalamus and Bcl-2,Bax protein expression levels of rats were detected by immunohistochemistry.The relative expressions of p38 MAPK,p-p38 MAPK,Bcl-2,Bax proteins in the hypothalamus of rats were detected by Western blot.Results A total of 301 active components,321 potential targets and 92 key targets were obtained.Key active components such as quercetin,kaempferol,luteolin,wogonin,sebiferic acid and β-sitosterol,as well as core targets such as MAPK,IL6 and TNF were obtained after screening.The key targets mainly focused on various signaling pathways such as TNF signaling pathway,MAPK signaling pathway,PI3K-Akt signaling pathway,dopaminergic synapse,and neuroactive ligand-receptor interaction,etc.Kaempferol,quercetin,digitonin and other flavonoids had good binding activity and stability with MAPK,TNF,IL6 and showed good affinity.The results of animal experiments showed that,compared with the normal group,the cognitive memory ability of the model group decreased(P<0.05),Nissl bodies were stained shallowly,the density was lower,the cell body was shrunk and deformed,the cell nucleus was broken and dissolved,and the serum and hypothalamic IL-6,TNF-α increased(P<0.05),the expressions of p-p38 MAPK/p38 MAPK and Bax in hypothalamus increased(P<0.05),while the expressions of Bcl-2 and Bcl-2/Bax decreased(P<0.05);compared with the model group,the cognitive memory ability of the TCM group and the Western medicine group were improved,the number of Nissl bodies significantly increased,the nucleus was clear,the cell body shrinkage and deformation were improved(P<0.05),the levels of IL-6 and TNF-α in serum and hypothalamus decreased(P<0.05),while the expressions of p-p38 MAPK/p38 MAPK and Bax decreased,and the expression of Bcl-2 and Bcl-2/Bax increased(P<0.05).Conclusion Yanggan Anhun Decoction may play its effects in treating insomnia with liver failing in storing soul type by regulating MAPK,TNF,IL6,Bcl-2,Bax and other core targets,and interfering with p38MAPK signaling pathway.

The liver plays an important regulatory role in maintaining the dynamic balance of coagulation and anticoagulation in the body. Such dynamic balance is fragile in patients with liver cirrhosis， and the risk of bleeding can be increased due to reductions in coagulation factors and platelet count and excessive fibrinolysis； meanwhile， thrombus can be formed due to the increases in von Willebrand factor and coagulation factor Ⅷ， the reductions in anticoagulant protein C and anticoagulant protein S， the increase in thrombin-generating potential， and alterations in antifibrinolytic components. This article reviews the mechanisms of coagulation disorder in liver cirrhosis， so as to help clinicians with the prevention and treatment of bleeding or thrombotic disorders in patients with liver cirrhosis.

Objective To investigate the role of lncRNA SNHG1 in homocysteine-induced pyroptosis of podocyte.Methods Cbs+/-mice were randomly divided into two groups:a normal diet group(ND)and a high me-thionine diet group(HMD).Western blotting was used to detect the protein expression levels of Caspase-1,Cleaved Caspase-1,and NLRP3.Mouse renal glomerular podocytes were cultured in vitro,and then assigned into a control group(Control,0 μmol/L Hcy)and a homocysteine intervention group(Hcy,80 μmol/L Hcy).Western blotting was used to detect the protein expression levels of Caspase-1,Cleaved Caspase-1,and NLRP3.Mouse renal glomerular podocyion group(OE-NC + Hcy)and the lncSNHG1 overexpression + homocysteine intervention group(OE-SNHG1 + Hcy)were also established.After 48 hours of intervention,Real-time fluorescence quantita-tive PCR was used to detect the expression of lncSNHG1 in podocytes after Hcy intervention.Western blot was used to detect the expressions of Caspase-1,Cleaved Caspase-3 and NLRP3.Immunofluorescence was used to de-tect the expression levels of GSDMD and GSDMD-N.ELISA was used to detect the contents of IL-1β and IL-18.Results(1)In the animal experiments,the expression levels of pyroptosis-related proteins Caspase-1,Cleaved Caspase-1,NLRP3,GSDMD,and GSDMD-N were all increased in the HMD group compared with the ND group.(2)In the cellular experiments,the expression levels of Caspase-1,Cleaved Caspase-1,NLRP3,GSDMD,and GSDMD-N were all increased in the Hcy group compared with the Control group,and the contents of pyroptosis-mediated inflammatory factors IL-1β and IL-18 were increased as well.(3)In the cellular experiments,the expres-sion of lncSNHG1 was increased in the Hcy group compared with the control group.After transduction with lnc-SNHG1 lentivirus,the expression of lncSNHG1 was increased in the OE-SNHG1 group,compared with the control group and the OE-NC group.(4)In the cellular experiments,the expressions of pyroptosis-related proteins Cas-pase-1,Cleaved Caspase-1,NLRP3,GSDMD,and GSDMD-N were increased compared with the OE-NC+Hcy group,and the contents of pyroptosis-mediated inflammatory factors IL-1β and IL-18 were increased in the OE-SNHG1+Hcy group.Conclusion These results indicate that lncSNHG1 may play a role in promoting Hcy induced podocytepyroptosis.

Rheumatoid arthritis （RA） is a systemic autoimmune disease with local joint pain as the main clinical manifestation. It is one of the diseases specifically responding to traditional Chinese medicine （TCM）. The occurrence of RA is not only related to innate factors like genetic disorder but also associated with environmental factors， such as diets and microbial infection. The intestine， a vital human organ with digestive and immune functions， is a place where microorganisms colonize and exert intestinal metabolism-improving， barrier-protecting， and immunomodulatory effects. As the research on the onset and treatment of RA is deepening， the potential relationship of intestinal structural and functional abnormalities with the pathogenesis and progression of RA has been revealed. As clinical and experimental studies indicated， joint inflammation coexists with the impaired barrier function， imbalanced immune cells， and disordered gut microbiota. The theory of the gut-joint axis in the pathogenesis， progression， and treatment of RA is highly consistent with the holistic view in TCM. The recent pharmacological studies have shown that Chinese medicine prescriptions and active components can inhibit inflammation， protect joints， and maintain the intestinal function. This article summarizes the basic connotation of the gut-joint axis in RA and the mechanism by which TCM protect the intestinal barrier and modulate the immunity by regulating the gut microbiota structure and improving microbial metabolism in the treatment of RA. This review gives insights into the future research on the gut-joint axis in RA.

Compared with the model group， the NREM stage and REM stage of the western medicine group and the TCM group were significantly increased （P<0.5， P<0.01）， and the wake stage was shortened （P<0.5）. The total time and distance of platform exploration were significantly decreased （P<0.01）. In the target quadrant （the third quadrant）， the percentage of exploration time and the times of crossing the platform were significantly increased （P<0.05， P<0.01）. The serum IL-10 level was significantly increased （P<0.01）， and the serum TNF-α level was significantly decreased according to the ELISA results （P<0.01）. The results of Western blot showed that the protein expression of IL-10 in brain tissue and lung tissue was significantly increased （P<0.01）， and the protein expression of TNF-α was significantly decreased （P<0.01）. The results of immunohistochemistry showed that the expression of IL-10 in brain tissue and lung tissue was significantly increased （P<0.05， P<0.01）， and the expression of TNF-α was significantly decreased （P<0.05， P<0.01）. ConclusionGuizhi Jia Longgu Mulitang can improve the expression of IL-10 and TNF-α in brain and lung tissue of insomnia rats with sensory dysfunction dominated by lung， prolong sleep time， and then improve insomnia. The mechanism may be related to improving the expression level of inflammatory factors.
