In March 2024, three male and two female specimens of the genus Lispe were intercepted on cargo ships inbound for Wan Zai Port under Gongbei Customs. Based on morphological characteristics and molecular analysis, the specimens were identified as Lispe pumila. In this study, we describe the morphological features, diagnostic characteristics, and geographical distribution of L. pumila, with the aim of providing a reference for the identification of this species when intercepted at ports.

Abstract In recent years, Chinese college students have shown increased awareness of the importance of physical exercise. However, challenges such as insufficient health literacy, declining physical fitness, and low participation rates in physical activity still persist. To address these issues, the study applies behavioral economics theory and incorporates concepts such as anchoring effects, intertemporal decision making, loss aversion, and herd behavior, to examine the irrational factors and decision making preferences underlying college students physical exercise behaviors. By analyzing the cognitive biases in their decision making processes, the research aims to propose targeted and scientifically validated intervention strategies, so as to provide references for improving college students engagement in physical exercise and promoting their overall well being.

Objective To explore the effect of mangiferin(MF)on pyroptosis in an amyotrophic lateral sclerosis(ALS)cell model by regulating the nuclear factor erythroid 2-related factor 2/heme oxygenase-1(Nrf2/HO-1)signaling pathway.Methods(1)Mouse NSC-34 cell lines transfected with hSOD1WT and hSOD1G93A plasmids were randomly divided into blank group,model group,MF(100 μmol/L)group,MF(200 μmol/L)group.MF was added into the culture plate for 24 hours.Cell viability was assessed using CCK-8 kit.Lactate dehydrogenase(LDH)release was measured using LDH cytotoxicity detection kit.Levels of inflammatory factors interleukin(IL)-1β and IL-18 in cell supernatant were determined by enzyme-linked immunosorbent assay(ELISA).The expression of Nrf2,HO-1,NADPH quinone oxidoreductase-1(NQO-1),NOD-like receptor protein 3(NLRP3),gasdermin D(GSDMD)-N and caspase-1 was detected by Western blotting.(2)Mouse hSOD1G93A NSC-34 cells were randomly divided into model group,MF(200 μmol/L)group,Nrf2-siRNA group and Nrf2-siRNA+MF(200 μmol/L)group.The cells were transiently transfected with Nrf2-siRNA using LipofectamineTM 3000.Western blotting was used to detect the protein expression levels of Nrf2,HO-1,NQO-1,NLRP3,caspase-1 and GSDMD-N.Results(1)The results of the CCK-8 assay showed that after the hSOD1G93A NSC-34 cells were treated with MF at concentrations of 300 μmol/L and below for 24 hours,the changes in cell viability were not significant(P>0.05).Compared with blank group,the release of LDH,the contents of IL-1β and IL-18 in the cell culture supernatant of model group were increased(P<0.001);the protein expression levels of Nrf2,HO-1,and NQO-1 were decreased(P<0.05 or P<0.01);the protein expression levels of NLRP3,caspase-1,and GSDMD-N were increased(P<0.05 or P<0.01 or P<0.001).Compared with model group,the release of LDH,the contents of IL-18 and IL-1β in the culture supernatant in MF(100 μmol/L)and MF(200 μmol/L)groups were decreased(P<0.001);the protein expression levels of NLRP3,caspase-1 and GSDMD-N were decreased(P<0.05 or P<0.001),and the expression levels of Nrf2,HO-1 and NQO-1 were increased(P<0.05 or P<0.01).(2)Compared with model group,the protein expession levels of Nrf2,NO-1 and NQO-1 were increased(P<0.05 or P<0.001)in MF(200 μmol/L)group,while the protein expression levels of NLRP3,caspase-1 and GSDMD-N were decreased(P<0.001);the protein expression levels of Nrf2 and HO-1 were decreased in Nrf2-siRNA group(P<0.01 or P<0.001),while the protein expression levels of NLRP3,caspase-1 and GSDMD-N were increased(P<0.001).Compared with Nrf2-siRNA group,the protein expression levels of Nrf2,HO-1 and NQO-1 in Nrf2-siRNA+MF(200 μmol/L)group were increased(P<0.01 or P<0.001),and the protein expression levels of NLRP3,caspase-1 and GSDMD-N were decreased(P<0.001).Conclusion MF can inhibit pyroptosis in the ALS cell model through Nrf2/HO-1 signaling pathway,playing a protective role.

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: The CT/MRI Liver Imaging Reporting and Data System (LI-RADS) demonstrates high specificity with relatively limited sensitivity for diagnosing hepatocellular carcinoma (HCC) in high-risk patients. This study aimed to explore the possibility of improving sensitivity by combining CT/MRI LI-RADS v2018 with second-line contrast-enhanced ultrasound (CEUS) LI-RADS v2017 using sulfur hexafluoride (SHF) or perfluorobutane (PFB). Materials and Methods: This retrospective analysis of prospectively collected multicenter data included high-risk patients with treatment-naive hepatic observations. The reference standard was pathological confirmation or a composite reference standard (only for benign lesions). Each participant underwent concurrent CT/MRI, SHF-enhanced US, and PFB-enhanced US examinations. The diagnostic performances for HCC of CT/MRI LI-RADS alone and three combination strategies (combining CT/ MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or a modified algorithm incorporating the Kupffer-phase findings for PFB [modified PFB]) were evaluated. For the three combination strategies, apart from the CT/MRI LR-5 criteria, HCC was diagnosed if CT/MRI LR-3 or LR-4 observations met the LR-5 criteria using LI-RADS SHF, LI-RADS PFB, or modified PFB. Results: In total, 281 participants (237 males; mean age, 55 ± 11 years) with 306 observations (227 HCCs, 40 non-HCC malignancies, and 39 benign lesions) were included. Using LI-RADS SHF, LI-RADS PFB, and modified PFB, 20, 23, and 31 CT/MRI LR-3/4 observations, respectively, were reclassified as LR-5, and all were pathologically confirmed as HCCs. Compared to CT/MRI LI-RADS alone (74%, 95% confidence interval [CI]: 68%–79%), the three combination strategies combining CT/MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or modified PFB increased sensitivity (83% [95% CI: 77%–87%], 84% [95% CI: 79%–89%], 88% [95% CI: 83%–92%], respectively; all P < 0.001), while maintaining the specificity at 92% (95% CI: 84%–97%). Conclusion The combination of CT/MRI LI-RADS with second-line CEUS using SHF or PFB improved the sensitivity of HCC diagnosis without compromising specificity.

Regulatory T cells(Tregs)are key regulators of the immune system and play important roles intumorigenesis and tumor progres-sion.They exert immunosuppressive effects through immune checkpoint pathways and by secreting inhibitory cytokines and specific chemokines as well as through other mechanisms that promote tumor immune escape.However,their mechanisms of action are complex and involve multistage,multifactorial processes.This article summarizes the mechanisms by which Tregs exert immunosuppressive effects in tumors and promote immune escape and describes related research progress.This study aims to provide a reference for an indepth under-standing of immune regulatory mechanisms in tumors and the development of novel therapeutic strategies.

AIM To investigate the clinical effects of Mahuang Fuzi Xixin Decoction combined with non-immunosuppressive treatment on patients with focal segmental glomerulosclerosis due to Spleen-Kidney Yang Deficiency.METHODS Sixty patients were randomly assigned into control group(30 cases)for 24-week intervention of non-immunosuppressive treatment,and observation group(30 cases)for 24-week intervention of both Mahuang Fuzi Xixin Decoction and non-immunosuppressive treatment.The changes in clinical effects,TCM syndrome effects,TCM syndrome score,24 h UTP,ALB,eGFR,Nephrin,Podocin and safety indices were detected.RESULTS The observation group demonstrated higher total effective rate and TCM syndrome effective rate than the control group(P＜0.05).After the treatment,the two groups displayed decreased TCM syndrome score,24 h UTP,Nephrin,Podocin(P＜0.05),and increased ALB(P＜0.05),especially for the observation group(P＜0.05).No obvious adverse reactions occured in the two groups.CONCLUSION For the patients with focal segmental glomerulosclerosis due to Spleen-Kidney Yang Deficiency,Mahuang Fuzi Xixin Decoction combined with non-immunosuppressive treatment can improve TCM syndromes,whose action mechanism may be contribute to the alleviation of podocyte injury.

AIM To investigate the effects of Wuzi Yanzong Pills on subacute aging-induced testicular trauma and AMPK/mTOR pathway in rats.METHODS Rat models of subacute aging were induced by 8-week subcutaneous injection of D-gal(200 mg/kg)into the rat neck,followed by their random assignment into the model group,the metformin group(0.3 g/kg)and the low-dose and high-dose Wuzi Yanzong Pills groups(0.54,2.16 g/kg),with 9 rats in each group,in contrast to the 8 intact rats of the normal group.And the corresponding drug was given by gavage for 4 weeks after modeling,after which the rats had their levels of serum T,FSH,SOD,LH,8-OHdG and MDA detected by ELISA;their pathological changes of testes observed by HE and β-galactosidase staining;and their expressions of aging-related proteins(p16,p21,p53),testicle secretory function-related proteins(CYP11A1,HSD17B3,STAR),autophagy-related proteins(p62,ATG5,Beclin-1,LC3B)and AMPK/mTOR pathway-related protein detected by Western blot and immunohistochemistry.RESULTS Compared with the normal group,the model group displayed morphologically smaller testes and body surface;dry hair;overall atrophic testicular tissue structure;increased testicular protein expressions of γ-H2AX,p16,p21 andβ-galactosidase(P＜0.05,P＜0.01);and decreased p53 protein expression(P＜0.05);suggesting the modeling success.Compared with the model group,the high-dose Wuzi Yanzong Pills group shared decreased levels of serum 8-OHdG,MDA,FSH and LH(P＜0.01);increased levels of SOD and T(P＜0.01);improved sperm damage and almost morphologically normal testicular tissue;decreased testicular protein expressions of p16,p21,p53,p62 and p-mTOR(P＜0.01);and increased protein expressions of CYP11A1,HSD17B3,STAR,ATG5,Beclin-1,LC3B and p-AMPK(P＜0.01).CONCLUSION Wuzi Yanzong Pills can improve the subacute aging-induced testicular injury and testicular function in rats by reducing their oxidative stress through improving their autophagy level and testicle antioxidant capacity.

Objective To explore the correlation between the expression of serum microRNA(miR)-1298-5p,miR-625-5p,and miR-155 with the degree of Helicobacter pylori(Hp)infection in elderly gastric cancer patients.Methods From January 2021 to November 2023,120 elderly patients with gastric cancer admitted to the hospital from January 2021 to November 2023 were selected as the gastric cancer group,and 130 non-gas-tric cancer patients who underwent gastroscopy were selected as the control group.The expression levels of miR-1298-5p,miR-625-5p and miR-155 in serum were detected by fluorescence quantitative PCR(qPCR).Car-bon 13 urea breath test was used to detect the positive rate of Hp infection in two groups,and the degree of Hp infection in elderly patients with gastric cancer were evaluated.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of serum miR-1298-5p,miR-625-5p,and miR-155 expression levels for Hp infection in elderly gastric cancer patients.Pearson method was applied to analyze the correlation between serum miR-1298-5p,miR-625-5p,miR-155 expression and positive rate of Hp infection in elderly gas-tric cancer patients.Results Compared with the control group,the expression levels of miR-1298-5p and miR-625-5p in serum of gastric cancer group decreased(P＜0.05),while the positive rate of Hp infection and the expression level of serum miR-155 increased(P＜0.05).The expression levels of serum miR-1298-5p and miR-625-5p in elderly gastric cancer patients with Hp grade Ⅰ,Ⅱ,and Ⅲ infection were lower than those without Hp infection,while the expression level of miR-155 was higher(P＜0.05).Patients with poor differ-entiation,lymph node metastasis,and TNM stage Ⅲ-Ⅳ had lower expressions of serum miR-1298-5p and miR-625-5p(P＜0.05),and higher expression of miR-155(P＜0.05)than those with moderate-high differen-tiation,no lymph node metastasis,and TNM stage Ⅰ-Ⅱ.The expression levels of serum miR-1298-5p and miR-625-5p were negatively correlated with the positive rate of Hp infection in elderly patients with gastric cancer(r=-0.443,-0.386,both P＜0.001),and the expression levels of serum miR-155 were positively correlated with the positive rate of Hp infection(r=0.525,P＜0.001).The area under the curve(AUC)of serum miR-1298-5p,miR-625-5p and miR-155 combined diagnosis of Hp infection in elderly gastric cancer pa-tients was higher than that of single diagnosis(P＜0.05).Conclusion The expression levels of miR-1298-5p and miR-625-5p in serum of elderly gastric cancer patients with Hp infection decrease,while the expression level of miR-155 increases.These three factors are related to the degree of Hp infection and have good diag-nostic value for the occurrence of Hp infection.

With the rapid development of social economy and the continuous improvement of human living standard, the incidence, fatality and recurrence rates of cardiovascular disease (CVD) are increasing year by year, which seriously affects people's life and health. Conventional therapeutic drugs have limited improvement on the disability rate, so the search for new therapeutic drugs and action targets has become one of the hotspots of current research. In recent years, the therapeutic role of the natural compound rosmarinic acid (RA) in CVD has attracted much attention, which is capable of preventing CVD by modulating multiple signalling pathways and exerting physiological activities such as antioxidant, anti-apoptotic, anti-inflammatory, anti-platelet aggregation, as well as anti-coagulation and endothelial function protection. In this paper, the role of RA in the prevention of CVD is systematically sorted out, and its mechanism of action is summarised and analysed, with a view to providing a scientific basis and important support for the in-depth exploration of the prevention value of RA in CVD and its further development as a prevention drug.
