Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Objective:To observe the effects of acupuncture on the motor function of Parkinson disease(PD)model mice and to investigate the neuroprotective effects of acupuncture on PD from the perspective of cellular senescence.Methods:C57BL/6J mice were randomly divided into a normal control(NC)group,a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)group,an acupuncture(ACU)group,and a rasagiline(RAS)group,with 6 mice in each group.Except for the mice in the NC group,all mice were injected intraperitoneally with MPTP[30 mg/(kg·bw)]to establish a PD mouse model.After the models were successfully established,mice in the ACU group received acupuncture at Baihui(GV20)and bilateral Yanglingquan(GB34)for 15 min,once a day for 14 consecutive days.Mice in the RAS group were treated with gavage of rasagiline mesylate[0.5 mg/(kg·bw)],once daily for 14 d.Mouse balance and motor functions were detected using the mouse fatigue rotating rod apparatus.Immunohistochemistry staining was used to detect the number of tyrosine hydroxylase(TH)-positive neurons and the protein expression levels of special AT-rich sequence-binding protein 1(SATB1),p21,and p53 in the substantia nigra(SN)region of the mouse brain in each group.The glutathione peroxidase(GSH-Px)activity of mouse brain SN tissue was detected by enzyme-linked immunosorbent assay.The protein expression levels of interleukin(IL)-6 and senescence-associated β-galactosidase(SA-β-gal)in the SN tissue of mice in each group were detected by Western blotting.The relative expression of SATB1,p21,and p53 mRNA in the SN of each group was detected by real-time quantitative polymerase chain reaction.Results:Compared to the NC group,the overall rod performance(ORP)score,the number of TH-positive neurons,and GSH-Px activity in the SN region were significantly lower in the mice in the MPTP group(P<0.01);compared to the MPTP group,the ORP score,the number of TH-positive neurons,and GSH-Px activity were significantly increased in the ACU group and the RAS group(P<0.01 or P<0.05).Compared to the NC group,the protein levels of IL-6 and SA-β-gal in the SN tissue,the protein and mRNA expression levels of p21 and p53 were significantly increased(P<0.01);compared to the MPTP group,the protein levels of IL-6 and SA-β-gal in the SN tissue,the protein and mRNA expression levels of p21 and p53 were significantly decreased in the ACU group and the RAS group(P<0.01 or P<0.05).Compared to the NC group,the relative expression of SATB1 protein and mRNA in the SN of mice in the MPTP group was significantly decreased(P<0.01);compared to mice in the MPTP group,mice in the ACU group and the RAS group showed significant increases in the relative expression of SATB1 protein and mRNA(P<0.01 or P<0.05).Conclusion:Acupuncture can improve motor function and increase the number of TH-positive neurons in the SN of PD model mice.Its neuroprotective effect may relate to the regulation of the SATB1/p21 signaling pathway and the inhibition of cellular senescence-related biomarker expression in the SN.

This study was aimed at determining the genetic characteristics of Yersinia pestis in Subei County through differ-ential region(DFR),clustered regularly interspaced short palindromic repeats(CRISPR),and variable number tandem repeat(VNTR)analyses,to guide the tracing of plague outbreaks.The DNA of 89 Yersinia pestis strains isolated from various ani-mal in foci of Subei County from 1973 to 2017 was extracted.Primers for genotyping by DFR,CRISPR,and MLVA were used in PCR,and agarose electrophoresis was used to determine whether the amplified products were present.Genotypes were deter-mined through comparison against the DFR database of Yersinia pestis in China.The PCR products were sequenced and com-pared against the online CRISPR database for Yersinia pestis to determine the genotype.The number of VNTR repeats in each strain was calculated through capillary electrophoresis,and the minimum spanning tree was constructed with BioNumerics 7.6 according to the numbers of VNTR repeats from 89 Yersinia pestis strains in Subei County and 11 strains from a Marmota hi-malayana focus in Qinghai Province.The Yersinia pestis strains in Subei County were divided into six main genotypes by DFR:8,7,lb,5,32,and 44.The Yersinia pestis strains were divided into three gene clusters and three genotypes by CRISPR.Ca35'was the main gene cluster in Subei County;the genotype was 26';and the distribution was primarily in Dangchengwan Town,Yuerhong Township,and Shibaocheng Township.Ca7 and CaΔ5'comprised secondary gene clusters,with genotypes 22 and 24,and were distributed in Dangchengwan Town,Yuerhong Township,and Shibaocheng Township.The Yersinia pes-tis strains in Subei County were divided primarily into three clusters:the Dangchengwan Machang cluster,Yuerhong Township cluster and Dangchengwan Town cluster.Therefore,the Yersinia pestis strains in Subei County,divided into major and minor genotypes according to DFR,CRISPR and MLVA,showed different regional distribution characteristics,highly diverse geno-types,and complex population characteristics.These aspects are particularly important in tracing the sources of plague out-breaks.

AIM:To study the protective effect of transient receptor potential vanilic acid subtype 1(TRPV1)agonist capsaicin(CAP)on traumatic blood loss shock rats,and to further explore its possible mechanism by network pharmacology.METHODS:Forty-five SD rats were divided into 5 groups by random number table method:normal group,shock group,lactated Ringer's solution(LR)group,CAP pretreatment(single administration before shock)group,CAP pre-final administration(twice administration before and after shock)group,with 9 rats in each group for survival observation.Then 32 SD rats were divided into 4 groups according to the results of survival experiment:normal group,shock group,LR group,CAP pre-final administration group,with 8 rats in each group for blood pressure,hemodynamics,arterial blood gas,vascular reactivi-ty and hepaticand renal blood flow.At the same time,the potential mechanism of CAP in the treat-ment of traumatic hemorrhagic shock was investi-gated by network pharmacology.Furthermore,ap-ply the dataset to validate and analyse the diagnos-tic value of the hub genes.RESULTS:Rats in shock group died within hours of the completion of the shock model,and the mean survival time was 1.25(0.42,6.21)h.LR resuscitation could improve the survival of rats to some extent.The survival rate and survival time of rats in the CAP pretreatment group were slightly increased as compared with the LR group,while twice administration of CAP be-fore and after shock(CAP pre-final administration)resulted in better outcomes than LR resuscitation alone.Further results indicated that CAP pre-final administration significantly reduced the blood lac-tic acid level,improved the vasoconstrictive and di-astolic reactivity,and increased the liver and kidney blood flow of shock rats as compared with LR group.The improvement of hemodynamics and blood gas indexes in CAP group was slightly higher than LR group,but there was no statistical signifi-cance.A total of 37 genes related to CAP anti-trau-matic hemorrhage shock were obtained by net-work pharmacology.KEGG enrichment analysis showed that the Ca ion signaling pathway and Ras signaling pathway were significantly enriched.Vali-dation of the dataset showed that the expression levels of CXCR4,NF-kB1,GFPA and NTF3 hub gene were significantly different in the normal and shock groups,and that CXCR4 has a high diagnostic value for traumatic haemorrhagic shock.CONCLUSIONS:CAP,the TRPV1 agonist,significantly improved vas-cular function,increased organ blood flow,and cor-rected the lactic acidosis in rats with traumatic hemorrhagic shock,thus markedly improved the survival outcomes.The mechanism may be related to Ca ion signal pathway and Ras signal pathway.CXCR4,NF-kB1,GFPA and NTF3 may be having an important role in it.

Objective:To establish a stable rat model of sequelae of pelvic inflammatory disease(SPID)with clinical characteristics,and to provide a reliable experimental model for the study of the pharmcological effect and mechanism of SPID.Methods:Twenty-four 7-week-old SD rats were divided into sham operation group,model-A(108 cfu/mL mixed bacterial solution,0.2 mL),model-B(109 cfu/mL mixed bacterial solution 0.2 mL),and model-C(108 cfu/mL E.coli 0.2 mL).The weight of the rat's uterine was weighed and the uterine index was calculated.The automatic hematology analyzer was used to detect the blood routine;hematoxylin-eosin staining(HE)and masson staining were used to detect uterine pathlogical changes in rats.Enzyme-linked immunosorbent assay(ELISA)was used to detect interleukin-1β(IL-1β),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)in rat uterine tissue homogenates.Western blot was used to detect the expression of proteins related to NF-κB signaling pathway.Results:Compared with the sham operation group,the uterine index of model-A,model-B,and model-C were significantly increased(P＜0.05,P＜0.01).The levels of WBC and NE in the model-A increased significantly(P＜0.01).The level of LY in model-B decreased significantly(P＜0.01).The levels of IL-1β,TNF-α in model-A,model-B,and model-C were significantly increased(P＜0.01).The levels of IL-6 in model-A and model-B were significantly increased(P＜0.05,P＜0.01).The collagen volume fraction of model-A and model-B were significantly increased(P＜0.01).Mechanism study indicates that the expression levels of p-IKKβ/IKKβ,p-IκBα/IκBα and p-p65/p65 in model-A were significantly increased(P＜0.01),and the expression levels of IκBα/β-actin were significantly decreased(P＜0.01).The expression level of p-IKKβ/IKKβ in model-B was significantly increased(P＜0.01).Conclusions:A stable rat model of SPID that conforms to clinical characteristics can be successfully constructed by combining 0.2 mL of mixed bacterial solution with a concentration of 108 cfu/mL and mechanical injury.This modeling method intervened in the expression of the NF-κB inflammatory signaling pathway.

This study was aimed at understanding the prevalence and influencing factors of food-borne parasitic diseases in ethnic minority areas of Guizhou Province,to provide a scientific basis for the development of appropriate intervention measures based on the human-animal-environment One Health concept.In 2023,the infection status of the human population,reservoir hosts,intermediate hosts,food-borne parasitic diseases,and related social and environmental factors were investigated in Congjiang County in Qidongnan Miao and Dong Autonomous Prefecture;Luodian County in Qiannan Buyi and Miao Autonomous Prefecture;and Ceheng County in Qianxinan Buyi and Miao Autonomous Prefecture.At least 1 000 individuals were sampled from each county,along with at least 50 insect-protected host samples from each location.Food-borne parasite infections were detected with the modified Kato thick smear method.A questionnaire survey was administered to the population.Detection of food-borne parasitic metacercariae was performed in intermediate host fish through the flaking and digestion method,and in crabs through the pounding and sedimentation method.The chi-square test was used to compare rates,and logistic regression was applied for multivariate analysis.A total of 3 023 questionnaires and fecal samples were collected.Males accounted for 47.50%,females accounted for 52.50%,and members of ethnic minorities accounted for 96.06%.A total of 186 food-borne parasitic infections were identified,and the infection rate was 6.15%.Five insect species were detected,which showed an infection rate of 5.39%.The infection rate of Clonorchis sinensis was 0.33%,that of Taenia was 0.40%,that of Heteroceles was 0.17%,that of Acanthus was 0.17%,and that of Echinostoma was 0.03%.Human infections with Echinostomus colloides and Echinostomia transferoris had not previously been reported in China.Single-factor analysis revealed statistically significant differences in food-borne parasite infections according to various factors,including the consumption of untreated water,raw fish and shrimp,raw pig blood,raw cow gastric juice,and raw pork and beef,as well as raw pig and cow viscera(P<0.05).Multivariate analysis indicated that the risk factors for food-borne parasite infections among residents in minority areas of Guizhou Province included the consumption of raw pig blood(OR=2.841,95%CI:1.809-4.463),raw cow gastric juice(OR=2.122,95%CI:1.297-3.469),and raw fish and shrimp(OR=1.779,95%CI:1.049-3.018).A total of 173 fecal samples of the reservoir host were examined,which showed a rate of food-borne parasite infection of 5.2%.A total of 510 intermediate host fish were examined,which showed a 4.51%positivity rate of encysted metacercaria of Clonorchis sinensis.The crab,pig,and beef samples were not positive.In conclusion,food-borne parasitic infections were prevalent in ethnic minority regions of Guizhou Province,and consumption of raw food were influencing factors.A focus on populations with raw food consumption habits,including raw pig blood,cow gastric juice,fish and shrimp,is essential.Concurrently,monitoring of animal hosts must be strengthened to perform key interventions according to the One Health concept.

Objective:To investigate multi-system involvement in Kennedy′s disease and its association with disease progression.Methods:We retrospectively reviewed the clinical, laboratory, and electrophysiological data from 48 genetically confirmed patients with Kennedy′s disease at the Department of Neurology, First Medical Center of the Chinese PLA General Hospital, between February 2016 and February 2024. The disease progression rate was calculated based on the functional scores at baseline and follow-up. Correlation analyses and multiple linear regression models were employed to assess the relationships among clinical variables and to identify potential predictors of disease progression.Results:The age of muscle weakness onset ranged from 16 to 66 years (mean 42±11 years), with a diagnostic delay of 5.0 (3.0, 9.8) years. Lower limb weakness was the most common initial symptom in 72.9% (35/48) of patients, and 37.5% (18/48) exhibited non-motor manifestations prior to the onset of weakness. Core motor manifestations included bulbar weakness (89.6%, 43/48) and symmetric proximal limb weakness (83.3%, 40/48), frequently accompanied by gynecomastia (74.2%, 23/31) and sexual dysfunction (64.6%, 31/48). The median CAG repeat length was 43 (42, 46), which showed a significant negative correlation with the age at onset ( r=-0.406, P=0.004). Patients with CAG repeats > 43 had a higher prevalence of sexual dysfunction. Elevated serum muscle enzymes were observed in 97.9% (47/48), and abnormal sex hormone levels were detected in 81.2% (39/48). Sensory neuropathy was present in 68.1% (32/47), with CAG repeat length inversely correlating with compound muscle action potential (CMAP) amplitudes in the median ( β=-0.29; t=-2.27, P=0.029) and ulnar ( β=-0.22; t=-2.23, P=0.031) nerves. Low-frequency repetitive nerve stimulation (RNS) revealed a decrement in 43.3% (13/30) of patients, most commonly affecting the axillary and spinal accessory nerves. The disease progression rate was 1.3±0.3 (range: 0.5-2.0). Furthermore, serum creatine kinase-MB (CK-MB) levels were negatively correlated with disease progression rate ( r=-0.303, P=0.036). Conclusions:Kennedy′s disease presents with diverse initial manifestations and frequent multi-system involvement. Non-motor manifestations may precede muscle weakness, serving as valuable clues for early diagnosis. Widespread sex hormone abnormalities (particularly testosterone/luteinizing hormone dysregulation) support the role of androgen insensitivity in disease pathogenesis. Sensory neuropathies are frequent and not length-dependent. The presence of decremental responses on low-frequency RNS suggests neuromuscular junction dysfunction, which may underlie motor impairment in patients with Kennedy′s disease. Finally, serum CK-MB may serve as a potential biomarker for disease progression.

Objective: To investigate the role of ferroptosis in transfusion-related acute lung injury (TRALI) and evaluate the efficacy of the specific inhibitor Ferrostatin-1 (Fer-1), thereby to provide a basis for the prevention and treatment of TRALI. Methods: This study utilized a ”2-hit” model to induce TRALI in mice. The mouse model of TRALI was validated through survival curve analysis, lung tissue wet/dry weight ratio (W/D), myeloperoxidase (MPO) activity, and total protein concentration in lung tissue. Samples from the TRALI model group, LPS group, and control group (n=6) were collected. The occurrence of ferroptosis in TRALI was confirmed by measuring key ferroptosis indicators, including iron concentration in lung tissue, malondialdehyde (MDA) level, lipid peroxidation products (LPO) level, and expression levels of related proteins (GPX4, ACSL4). Additionally, a Fer-1 intervention group was added to evaluate its preventive and therapeutic effects. The survival rates and clinical symptoms of the four groups (n=6) were dynamically monitored, and the degrees of lung injury were assessed. Ferroptosis-related indicators were also measured to elucidate the protective mechanism of Fer-1. Results: A mouse model of TRALI was successfully established. Compared to the control and LPS groups, the TRALI group showed significantly higher levels of ferrous iron [(18.32±1.11) nmol/well, MDA [(14.68±0.96) μmol/L], and LPO [(1.60±0.02) μmol/L] in lung tissue (all P<0.01), along with a downregulation of GPX4 and an upregulation of ACSL4. Fer-1 pretreatment significantly reversed these abnormalities: the W/D ratio decreased to 4.01±0.43, and MPO activity significantly decreased [Fer-1 group: (21 606±4 235) pg/mL vs TRALI group: (30 724±2 616) pg/mL], the total protein concentration in lung tissue of the Fer-1 group decreased by approximately 40.8% compared to the TRALI group (all P<0.01). These changes indicate that the lung injury in mice was alleviated after treatment. Following Fer-1 intervention, ferrous iron concentration [(7.46±1.83) nmol/well] was restored to a level close to that of the control group [(5.48±0.70) nmol/well]. Lipid peroxidation tests further revealed that Fer-1 intervention reduced MDA and LPO levels by 35.8% and 29.4%, respectively (P<0.001). Additionally, the expression levels of GPX4 and ACSL4 proteins returned to near-normal levels in the treated mice (both P>0.05). Conclusion: The progression of TRALI is closely related to the activation of ferroptosis, characterized by iron overload, lipid peroxidation accumulation, and the imbalance of GPX4/ACSL4. Ferrostatin-1 significantly alleviates pulmonary edema and inflammatory damage by inhibiting the ferroptosis pathway, suggesting that targeting ferroptosis may provide a new therapeutic strategy for TRALI.
