Pinellia ternata, belonging to the Pinellia genus within the Araceae family, is a medicinal plant due to its tubers. There are severe issues with unclear germplasm and mixed varieties in its cultivation, necessitating urgent new variety protection efforts. The distinctness, uniformity, and stability (DUS) testing of the plant variety is the basis for protecting new plant varieties, and the DUS test guidelines are the technical basis for DUS testing. To develop the DUS test guidelines for P. ternata, agronomic traits of 229 germplasm of P. ternata were observed and measured during its two growth stages over the years, and each character was graded and described. A total of 38 traits were selected as the test traits of the DUS test guideline for P. ternata. There were three plant traits, 19 leaf traits, six flower traits, two fruit traits, two tuber traits, five bulbil traits, and one ploidy trait. These traits could be divided into 22 quality characters, 12 quantitative characters, and four pseudo-quantitative characters, as well as seven groups, including plants, leaves, flowers, fruit, tubers, bulbils, and ploidy. By searching for standard traits, 10 standard varieties were ultimately determined. Preparing these guidelines will have great significance for reviewing and protecting P. ternata varieties, safeguarding breeders' rights, and promoting the development of the P. ternata industry.

Pharmacotranscriptomic profiles, which capture drug-induced changes in gene expression, offer vast potential for computational drug discovery and are widely used in modern medicine. However, current computational approaches neglected the associations within gene‒gene functional networks and unrevealed the systematic relationship between drug efficacy and the reversal effect. Here, we developed a new genome-scale functional module (GSFM) transformation framework to quantitatively evaluate drug efficacy for in silico drug discovery. GSFM employs four biologically interpretable quantifiers: GSFM_Up, GSFM_Down, GSFM_ssGSEA, and GSFM_TF to comprehensively evaluate the multi-dimension activities of each functional module (FM) at gene-level, pathway-level, and transcriptional regulatory network-level. Through a data transformation strategy, GSFM effectively converts noisy and potentially unreliable gene expression data into a more dependable FM active matrix, significantly outperforming other methods in terms of both robustness and accuracy. Besides, we found a positive correlation between RSGSFM and drug efficacy, suggesting that RSGSFM could serve as representative measure of drug efficacy. Furthermore, we identified WYE-354, perhexiline, and NTNCB as candidate therapeutic agents for the treatment of breast-invasive carcinoma, lung adenocarcinoma, and castration-resistant prostate cancer, respectively. The results from in vitro and in vivo experiments have validated that all identified compounds exhibit potent anti-tumor effects, providing proof-of-concept for our computational approach.

Objective To investigate the effect of Dex on neurological function in PD rats through the receptor interacting protein kinase 1(RIPK1)/RIPK3/mixed lineage kinase domain-like pro-tein(MLKL)pathway.Methods After rat PD model was constructed,the PD rats were assigned into PD group,L-,M-and H-Dex groups(intraperitoneal injection of 25,50,and 100 μg/kg Dex,respectively),and Dex+recombinant RIPK1 protein(rRIPK1)group(intraperitoneal injection of 100 μg/kg Dex+8 μg/kg rRIPK1),with 6 animals in each group.Another 6 rats served as sham-operation(Sham)group.The rats from the Sham group and PD group were intragastrically ad-ministered and injected with an equal amount of normal saline solution once a day.After 21 con-secutive days,the rotational behavior was observed of in each group rats.HE staining was per-formed to detect the pathological changes in dopaminergic neurons in the substantia nigra.TUNEL staining was conducted to measure the apoptosis of dopaminergic neurons.ELISA was used to determine the levels of neurotransmitters[DA,HVA,3,4-dihydroxyphenylacetic acid(DOPAC),5-hydroxytrptamine(5-HT)]and inflammatory factors(TNF-α,IL-1β)in the sub-stantia nigra.Western blotting was applied to detect the expression of RIPK1/RIPK3/MLKL pathway related proteins in the substantia nigra tissues.Results Intact and well-arranged mor-phology and structure were observed in the neurons of the Sham group.The PD group presented prominently less neurons,in scattered arrangement,with obviously reduced volume,irregular nu-clear deformation,indicating notably neuronal damage.The severity of neuronal damage was at-tenuated sequentially in the L-Dex,M-Dex,and H-Dex groups,but the damage in the Dex+rRIPK1 group was further worsened.The PD group had significantly larger number of rotations,longer escape latency,higher apoptotic rate,increased TNF-α and IL-1β contents,and elevated lev-els of p-RIPK1/RIPK1(1.07±0.18 vs 0.36±0.11),p-RIPK3/RIPK3(1.32±0.21 vs 0.47±0.14),and p-MLKL/MLKL(0.79±0.11 vs 0.18±0.05),but lower DA,DOPAC,5-HT,and HVA con-tents than the Sham group(P<0.05).Dex treatment of low,medium and high doses reserved all above changes induced by PD modeling(P<0.05).The Dex+rRIPK1 group obtained larger num-ber of rotations,longer escape latency,higher apoptotic rate,increased TNF-α and IL-1β contents,and elevated levels of p-RIPK1/RIPK1(0.95±0.17 vs 0.41±0.12),p-RIPK3/RIPK3(1.14±0.20 vs 0.51±0.15),and p-MLKL/MLKL(0.72±0.09 vs 0.24±0.06),but decreased DA,DOPAC,5-HT,and HVA contents when compared with the H-Dex group(P<0.05).Conclusion Dex protects the neurological function of PD rats by inhibiting the RIPK1/RIPK3/MLKL pathway.

Aim To systematically investigate the ac-tive components,targets,and regulatory pathways of Po-lygonum capitatum in intervening atherosclerosis(AS)through network pharmacology,molecular docking and animal experiments.Methods Active components of Polygonum capitatum and AS-related targets were screened and identified through database searches.Protein-protein interaction(PPI)network analysis was performed using the STRING database,followed by GO and KEGG enrichment analyses via the David plat-form.Molecular docking validation was conducted with AutoDock.An AS model was established in Syrian golden hamsters fed a high-fat diet.Predicted pathways and targets were validated using qPCR,ELISA,and histopathological assessment of aortic and hepatic tis-sues via HE staining.Results Network pharmacology identified 27 potential active components of Polygonum capitatum(primarily flavonoids such as quercetin and luteolin)and 110 drug-disease intersection targets,in-cluding core targets MMP-9,ALB,and AKT1.GO and KEGG analyses enriched 593 and 125 pathways,re-spectively,with the NF-κB inflammatory pathway,TNF signaling pathway and lipid metabolism/atherosclerosis pathways highlighted as key mechanisms.Animal ex-periments demonstrated that Polygonum capitatum im-proved serum lipid profiles(reduced TC,TG,LDL-C)in AS hamsters,suppressed the MMP-9/NF-κB signa-ling pathway(downregulated MMP-9,p65 phosphoryla-tion,TNF-α,and IL-6),and inhibited VSMC synthetic phenotypic transformation(upregulated α-SMA and myocardin)by downregulating MCPIP1.Additionally,Polygonum capitatum ameliorated aortic lesions and he-patic lipid deposition in AS hamsters.Conclusions Polygonum capitatum alleviates AS by synergistically regulating the MMP-9/NF-κB/MCPIP1 axis through flavonoid components,suppressing vascular inflammato-ry cascades and maintaining VSMC contractile pheno-types.This reflects Polygonum capitatum's multi-com-ponent,multi-pathway,and multi-target characteristics in combating AS.

Objective This study used resting-state functional magnetic resonance imaging(rs-fMRI)to investigate the changes of local brain regional homogeneity in patients with depression and childhood maltreatment,and we calculated the relationship between altered ReHo values and the severity of childhood maltreatment.Methods 25 patients with depression and childhood maltreatment,25 patients with depression without childhood maltreatment,and 25 age,gender,and education-matched healthy controls were prospectively enrolled.All subjects underwent resting-state functional magnetic resonance imaging and ReHo analysis.One-way analysis of variance was used to compare the group differences,along with multiple comparison correction.Pearson correlation analysis was used to explore the relationship between region ReHo values with clinical scales.Results Compared with the group of depression without childhood maltreatment,the abnormal brain regions of depression with childhood maltreatment are mainly located in the dorsolateral prefrontal cortex,cerebellum,parietal gyrus,and precentral gyrus.The ReHo values of depression with childhood maltreatment in the left cerebellum and the left dorsolateral prefrontal cortex are correlated with the severity of childhood maltreatment.Conclusions Depression with childhood mal-treatment is associated with changes in local spontaneous brain activity,which are correlated with the severity of childhood maltreatment.The brain changes in the dorsolateral prefrontal cortex and cerebellum may explain the neurobiological mechanisms of depression with childhood maltreatment.
