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 RS_GSFM and drug efficacy, suggesting that RS_GSFM 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.

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 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.

Objective To observe the mid-and long-term effects of Kegel training combined with Pilates training on urinary conti-nence recovery in different body mass index(BMI)male patients with urinary incontinence after prostatectomy.Methods From May,2023 to June,2024,48 patients in Beijing Bo'ai Hospital were recruited and divided into group A(<25 kg/m2,n=15),group B(25 to 30 kg/m2,n=18)and group C(>30 kg/m2,n=15)according to their BMI.All the groups performed Kegel training combined with Pilates training for two months,and followed up at six months from baseline.They were evaluated with one hour pad test,the number of daily urinary incontinence,In-ternational Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF)and modified Oxford Rating Scale before treatment,and four weeks,eight weeks and six months after treatment.Results The intra-group effect,the inter-group effect and interaction effect were significant in the results of one hour pad test and the daily number of urinary incontinence(F>2.955,P<0.05).Post Hoc test showed that they were worse in group C than in groups A and B(P<0.05),and the number of daily urinary incontinence was more in group B than in group A(P<0.05).There was significant difference in the scores of ICIQ-SF and modified Ox-ford Rating Scale among groups in different time points after treatment(Z>10.476,P<0.05)except the score of ICIQ-SF four weeks after treatment(P>0.05),and they were the worst in group C.BMI(group A=1,group B=2,group C=3)was correlated with the results of one hour pad test(r=0.79,P<0.001),the number of daily uri-nary incontinence(r=0.68,P<0.001),and the scores of ICIQ-SF(r=0.68,P<0.001)and modified Oxford Rating Scale(r=-0.47,P=0.001)six months after treatment.Conclusion Kegel training combined with Pilates training could improve the urinary control in patients with urinary in-continence after prostatectomy.The decrease of BMI can promote the recovery of urinary control,and improve the symptoms of later urinary incontinence in mid-and long-term.

Objective To develop a self-care scale for patients with lymphedema after breast cancer surgery and verify its reliability and validity.Methods Based on the model of knowledge,belief and practice,a questionnaire item pool was constructed after literature reviews and qualitative interviews.A questionnaire-based scale was drafted based on the established item pool by carrying out two rounds of consultation with 15 clinical nursing specialists,nursing administrators and nursing educators from 8 provinces or cities in China.Reliability and validity of the scale were tested using convenience sampling,involving 444 patients with breast cancer surgery related lymphedema from 7 general hospitals in Hubei and Henan provinces,China,between May and July 2023.Results The response rates for the two rounds of expert consultation were 93.75%and 93.33%,respectively.The authority coefficients of the two rounds were 0.86 and 0.89,respectively,and the coordination coefficients for the 2 rounds were 0.130 and 0.379,respectively.In the first round,the average importance rating was from 4.33 to 4.93 with the coefficient of variation from 0.05 to 0.19,and the full score ratio from 53.33%to 93.33%.In the second round,the average importance rating ranged from 2.86 to 4.93 with the coefficient of variation from 0.05 to 0.36,and the full score ratios from 7.14%to 92.86%.A total of 421 patients completed the survey.The overall Cronbach's α coefficient of the scale was 0.943,the overall split-half reliability was 0.824,the scale-level content validity index(S-CVI)was 0.912,and the item-level content validity index(I-CVI)of the total scale ranged from 0.857 to 1.000.The KMO value of exploratory factor analysis was 0.919,the Bartrett spherical test value was 4671.724(P<0.001),and the cumulative variance contribution rate was 64.155%.Confirmatory factor analysis showed a good model fit.After the reliability and validity tests,the scale was finalised and determined to consist of three dimensions with 33 items:knowledge(9 items),attitude(6 items)and behaviour(18 items).Conclusion The self-care scale for the patients with lymphedema after breast cancer surgery has demonstrated good reliability and validity,and makes it an effective assessment tool for the patients with lymphedema after breast cancer surgery.

ObjectiveTo observe the effects of Xibining （XBN） and adipose stem cell exosome （ADSC-Exos） in the cases of separate or joint application on cartilage degeneration and mitochondrial autophagy and explore its mechanism of action to improve knee osteoarthritis （KOA）. MethodSD rats were divided into a sham operation group （sham group）， a model group， an ADSC-Exos group （Exos group）， an XBN group， and an ADSC-Exos+XBN group （Exos+XBN group）. KOA model was established by using anterior cruciate ligament transection （ACLT）. The pain sensitivity status of rats was evaluated， and the degeneration degree of the knee joint and cartilage tissue was detected by Micro-CT and pathological staining. The expression of p62 and LC3B was observed by immunofluorescence， and the serum levels of TNF-α， IL-1β， IL-6， and IL-15 in rats were detected by ELISA. The Western blot was used to detect the protein expression levels of MMP-3， MMP-13， ADAMTS5， ColⅡ， TIMP， ACAN， PINK1， Parkin， p62， and LC3A/B. ResultCompared with the sham group， rats in the model group showed decreased cold-stimulated foot-shrinkage thresholds and mechanical pain sensitivity thresholds， varying degrees of abrasion and loss of cartilage tissue， degeneration of cartilage tissue， elevated serum IL-1β， IL-6， IL-15， and TNF-α levels （P<0.01）， and increased protein expression of MMP-3， MMP-13， and ADAMTS5 in cartilage tissue. In addition， the protein expression of ColⅡ， TIMP1， and ACAN was decreased （P<0.01）. Compared with the model group， rats in each treatment group showed higher cold-stimulated foot-shrinkage thresholds and mechanical pain sensitivity thresholds， reduced cartilage tissue degeneration， lower serum levels of IL-1β， IL-6， IL-15， and TNF-α （P<0.05，P<0.01）， decreased protein expression of MMP-3， MMP-13， and ADAMTS5， and higher protein expression of Cold， TIMP1， and ACAN in cartilage tissue （P<0.05，P<0.01）. Moreover， the changes were the most obvious in the Exos+XBN group. ConclusionBoth ADSCs-Exos and XBN can increase the level of mitochondrial autophagy in chondrocytes and delay cartilage tissue degeneration by promoting the expression of the PINK1/Parkin signaling pathway， and the combination of the two can enhance the therapeutic effect.
