Objective To assess the risk of human Spirometra mansoni infections and investigate the knowledge, attitude and practice (KAP) towards sparganosis mansoni among residents in Henan Province, so as to provide insights into formulation of the sparganosis mansoni control measures. Methods Qinling Village in Fugou County of Zhoukou City, Bali Village in Yancheng District of Luohe City, Duzhai Village in Puyang County of Puyang City and Doushan Village in Luoshan County of Xinyang City were sampled as survey sites in Henan Province from July to August 2023, and more than 40 frogs were sampled from ponds or streams in each survey site for detection of Sparganum mansoni infections. At least 150 residents were sampled using a cluster sampling method from each survey site, and the sero-prevalence of anti-S. mansoni IgG antibody was estimated. In addition, a questionnaire survey was conducted on the KAP towards sparganosis mansoni among participants, and the proportion of eligible KAP, rate of correct KAP and KAP scores were calculated. Results A total 229 frogs were collected from 4 survey sites in 2023, and the overall prevalence of S. mansoni infection was 4.37% (10/229) in frogs, with 7.75% (10/129) prevalence in wild frogs and 0 in farm-bred frogs. A questionnaire survey was performed among 649 residents sampled from 4 survey sites, and 649 serum samples were collected. The seroprevalence of anti-S.mansoni IgG antibody was 0.15% (1/649) and the overall proportion of eligible KAP was 23.73% (154/649) among participants. There were age- (χ² = 30.905, P = 0.000), educational level- (χ² = 41.011, P = 0.000), and occupation-specific proportions of eligible KAP among participants (χ² = 10.721, P = 0.005), and the proportion of eligible KAP decreased with age (χ² _trend = 22.717, P = 0.000) and increased with education levels (χ² _trend = 40.025, P = 0.000). The rates of correct KAP towards sparganosis mansoni were 40.81% (2 119/5 192), 96.66% (1 882/1 947) and 63.81% (3 727/5 841) (χ² = 1 913.731, P = 0.000) among residents, respectively. The rates of correct KAP towards sparganosis mansoni varied significantly among survey sites (χ² = 136.872, 42.347 and 255.157; all P values= 0.000, with the highest rate of correct knowledge (51.94%, 748/1 440) and practices (75.86%, 1 229/1 620) in Yancheng District of Luohe City and the highest rate of correct attitudes in Puyang County of Puyang City (99.11%, 446/450) (all P values< 0.05). Conclusions There is still a high transmission risk of sparganosis mansoni in Henan Province, and the KAP towards sparganosis mansoni is required to be improved among residents.

Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

IgG4-related disease (IgG4-RD) involving the ureter manifested as a ureteral tumor is rare. This paper reports a case of a female patient who was found with a mass at the left ureteropelvic junction for one week during physical examination. Urinary ultrasound and MRI showed a 3 cm mass at the left ureteropelvic junction with hydronephrosis, and the serum level of IgG4 was elevated. B-ultrasonic guided biopsy of the mass was performed. Histopathological findings showed lymphoplasmic infiltration and the ratio of IgG4/IgG positive cells>0.5. We finally diagnosed IgG4-RD and started using glucocorticoid for her treatment. One month later, CT-scan revealed that the tumor became smaller and the serum IgG4 decreased to the normal range.

Ectopic prostate is rare.This paper reports a case of a male patient who was found a mass in the pelvis for 20 days during physical examination.Urinary ultrasound, CT scan and MRI showed a pelvic mass that was about 4 cm×5 cm in size.Serum total prostate specific antigen (tPSA) was 6.09 ng/ml, and free PSA (fPSA) was 1.97 ng/ml. B-ultrasonic guided biopsy of the prostate and the mass was performed. Pathological findings suggest benign prostatic hyperplasia, weakly positive P504S and positive 34βE12. Pelvic mass is the prostate tissue with negative P504S and positive 34βE12. Finally, the ectopic prostate was diagnosed. Although it is rare, ectopic prostate should also be considered as a differential diagnosis of the pelvic tumor.

Objective:To explore the molecular mechanism through which repetitive transcranial magnetic stimulation (rTMS) promotes nerve regeneration after ischemic stroke.Methods:The miRNA expression profile in rats after rTMS was downloaded from the GEO database. Differentially-expressed miRNAs were identified using R software, and their corresponding mRNAs were predicted using the online database in order to construct miRNA-mRNA regulatory networks and identify the key miRNAs. The protein interaction network encoded by each gene was constructed by functional enrichment analysis, and the core mRNAs in the network were identified. Twenty-four male Sprague-Dawley rats of a specific pathogen-free grade were randomly divided into a sham operation group, a model group and a magnetic stimulation group, each of 8, and a stroke model was induced in the model and magnetic stimulation groups. The magnetic stimulation group then received rTMS for 7 consecutive days, while the other 2 groups did not. Modified neural function scores (mNSSs) were used to quantify neural function deficits before the experiment and 1, 3 and 7 days after the modeling. Eight days after the modeling, brain tissues were sampled for hematoxylin-eosin and Nishin staining to observe tissue loss and neuron morphology. Real-time fluorescence quantitative polymerase chain reactions were employed to verify the differential gene expression in the ischemic cortex.Results:A total of 167 different miRNAs were screened, and 25 mRNAs were predicted. Enrichment analysis showed that those genes are related to the positive regulation of cell migration and the positive regulation of neurotrophic factor receptor signaling pathways, including adenylate-activated protein kinase, the neurotrophic factor pathway, and rat sarcoma signaling pathways. The miRNA-mRNA regulatory network highlighted miR-206-3p, miR-378a-3p, miR-107-3p, miR-92a-3p and miR-29b-3p as key miRNAs. Integrin subunit β1, aquaporin 4, brain-derived nerve growth factor (BDNF), and member 4 of solutes vector family 2 were identified as key mRNAs by the protein interaction network analysis. Seven days after the modeling, the average mNSS score of the magnetic stimulation group was significantly lower than the model group′s average. Compared with the model group, the expression of miR-206-3p in the right cortex of the magnetic stimulation group had decreased significantly, while BDNF expression had increased significantly.Conclusions:miR-206-3p-BDNF pathways play an important role in neural repair promoted by rTMS.

OBJECTIVE To explore the mechanism of Yishen tongluo formula （YSTLF） in improving abnormal lipid metabolism based on the sterol regulatory element binding proteins （SREBPs） pathway. METHODS Using C57BLKS/J （db/db） mice as model and C57BLKS/J （db/m） mice as normal control， the mechanism of 1， 2.5 and 5 g/kg YSTLF improving abnormal lipid metabolism of db/db mice was investigated by determining the liver coefficient， the contents of serum total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein （LDL） and high-density lipoprotein （HDL）， observing steatosis and lipid accumulation in liver tissue of mice， detecting the protein expressions of SREBP-1 and SREBP-2 as well as mRNA transcription levels of Srebp- 1c， Srebp-2 and their downstream lipid metabolism-related target genes （Fasn， Acc1， Scd5， Fads1， Hmgcr， Dhcr24， Insig-1， Fdps） in liver tissue of mice. Using low-fat cultured human liver cancer cell HepG2 as an in vitro cell model for abnormal lipid metabolism， and 25-HC （SREBPs inhibitor， 10 μmol/L） as the control， the effects of 125， 250 and 500 μg/mL YSTLF on protein expressions of SREBP-1 and SREBP-2 as well as mRNA transcription of SREBP-1c， SREBP-2 and their downstream lipid metabolism-related target genes were investigated to verify the mechanism in vitro. RESULTS 1， 2.5， 5 g/kg YSTLF significantly reduced the levels of TC， TG and LDL， the percentage of lipid droplet-positive region in liver tissue and liver coefficient， significantly down-regulated protein expressions of Pre-SREBP-1， n-SREBP-1， Pre-SREBP-2 and n-SREBP-2， and mRNA transcription of Srebp-1c， Srebp-2 and their downstream target genes in liver tissue， while significantly increased HDL level， with statistical significance （P＜0.05 or P＜0.01）. In the cell experiment in vitro， the expressions of the above-mentioned proteins and genes in the cells treated with YSTLF at 125， 250 and 500 μg/mL for 24 hours were consistent with those in the animal experiment； there was no significant difference in the expressions of the above-mentioned proteins and genes between inhibitor control group and 250， 500 μg/mL YSTLF groups （P＞0.05）. CONCLUSIONS YSTLF can regulate the expression of transcription factor SREBPs， so as to inhibit the high expression of fatty acid and cholesterol synthesis-related genes， promote the degradation of TC and TG， improve the abnormality of lipid metabolism and inhibit lipid accumulation， thus playing the role of lipid-lowering.
