Objective:To analyze the clinical features, imaging features and diagnosis and treatment process of a female pelvic epithelioid inflammatory myofibroblastic sarcoma (EIMS) with peritoneal metastasis, so as to improve the clinical understanding and diagnostic ability of the disease and avoid misdiagnosis and missed diagnosis.Methods:The clinical data of a female patient with pelvic EIMS combined with peritoneal metastasis in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed.Results:The triad examination of the patient involved an irregular solid mass in the pelvic cavity about 8.0 cm×9.0 cm in size. Laboratory examination revealed human epididymal protein 4(HE4)154.00 pmol/L. The ultrasonography showed multiple low-echo masses in deep pelvic cavity with unclear boundary and uneven internal echo, and color doppler flow imaging (CDFI) showed abundant internal blood flow signals. Enhanced CT showed uneven and obvious enhancement of the lesion. Pathological examination showed the infiltration of inflammatory cells in the mucous interstitial background. The tumor cells were round and epithelioid, with large nuclei, deep staining and obvious nucleolus. Immunohistochemistry showed anaplastic lymphoma kinase (ALK) positive, and molecular pathology fluorescence in situ hybridization showed ALK gene amplification (positive). Combined with pathological, immunohistochemical and genetic tests, EIMS was diagnosed. Conclusions:EIMS should be considered when there are single or multiple solid or cystic nodules or masses in the pelvic cavity with obvious enhancement, invasive growth and peritoneal implantation metastasis, and the correct diagnosis can be made according to the pathological findings, immunohistochemistry and genetic test results.

Polygonatum sibiricum polysaccharide(PSP)is a polysaccharide with multiple pharma-cological activities that has been widely studied and used in the human body.However,there is cur-rently a lack of research investigating the potential advantages of PSP in poultry farming.This study investigated the effects of adding PSP to drinking water on the growth performance,antioxi-dant status,serum biochemical indicators,ileal tissue morphology,immune organs,and intestinal function of chicks.88 Hailan brown laying hens were randomly divided into 4 groups,with 22 hens in each group,namely the blank control group(CON),and fed with basic feed;The low-dose PSP group(250 mg/L),the medium dose PSP group(500 mg/L),and the high-dose PSP group(1 000 mg/L)were fed with corresponding doses of PSP through drinking water on the basis of basic feed,and the experimental period was 21 d.The initial and final body weight and immune or-gan relative quality of chicks,serum biochemical indicators,the activities of SOD,CAT,and GSH-Px,as well as the contents of T-AOC and MDA in the serum of chicks were measured;HE stai-ning method was used to observe the pathological changes of intestinal tissue slices in the ileum;Real time fluorescence quantitative PCR technology was used to detect the mRNA expression lev-els of cytokines ZO-1,Claudin-1,Occludin,Mucin-2,IL-1β,TNF-a,IFN-γ,IL-4,IL-8,and IL-10 in the ileum.The results showed that compared with the blank control group,the addition of medium dose PSP significantly increased the final relative quality(P＜0.01),the final body weight and ADG of PSP500 group chicks significantly increased(P＜0.01),and the F/G of PSP250 and PSP500 groups significantly decreased(P＜0.05 or P＜0.01).The villus height of the jejunum in the 200,500,and 1 000 mg/L PSP groups of chicks significantly increased(P＜0.05).The SOD ac-tivity significantly increased(P＜0.01),and the CAT activity in the PSP1000 group significantly increased(P＜0.01).The PSP500 and PSP1000 groups significantly reduced the mRNA expression of cytokines IL-1β,IL-4,and IFN-γ in the ileum(P＞0.05);PSP did not show significant changes in serum total protein(TP),albumin(ALB),glucose(GLU),cholesterol(T-CHO)content,and immune organ index(P＜0.05).In summary,PSP can improve growth performance,enhance an-tioxidant capacity,improve ileal morphology and epithelial barrier function,and regulate mucosal immune status.Considering the overall economic benefits,the recommended level of PSP addition is 500 mg/L.

Objective: To investigate the intentions of mothers of ageappropriate girls in Qingdao to vaccinate their daughters against human papillomavirus (HPV), so as to provide theoretical guidance for targeted health education in the future. Methods: A multistage random sampling method was adopted to conduct a crosssectional study among 2 244 mothers of girls aged 12-14 years in Qingdao from March to December 2023. The Mann-Whitney U test was used for group comparisons, and Logistic regression was performed to analyze the factors that influenced maternal intention to vaccinate their ageappropriate daughters against HPV. Results: Among the surveyed mothers, 89.22% (n=2 002) intended to vaccinate their daughters against HPV, and 68.58% (n=1 539) had fully vaccinated or had plans to complete it for themselves. The knowledge score of mothers intended to vaccinate their daughters was 10 (8, 11). The multivariate Logistic regression analysis showed that mothers aged >45 years (OR=0.19), those with an annual family income of 60 000-<150 000 yuan (OR=0.65), 150 000-<300 000 yuan (OR=0.58), 300 000-500 000 yuan (OR=0.22), and those with higher knowledge scores (OR=0.90) were more likely to vaccinate their daughters (P<0.05). Mothers with a junior college or undergraduate degree (OR=1.66), those who never or occasionally screened for HPV (OR=1.58), those who were intended to be vaccinated, not planning to complete the fullcourse vaccination, or overaged and unvaccinated (OR=7.13), those who were not concerned about their daughters HPV infection (OR=2.54), and those whose daughters were not in adolescence (OR=1.93) were less intended to vaccinate their daughters (P<0.05). The primary reasons for vaccine hesitancy were vaccine safety concerns (65.06%), followed by the belief of mothers that "the children is to young, and can be vaccinated when they are older" (13.25%). Conclusions Mothers of eligible girls in Qingdao have relatively higher intentions to vaccinate their daughters against HPV, and willingness is influenced by factors such as the mothers vaccination status, knowledge level, and daughters development stage. It is recommended to strengthen targeted health education, improve the cognitive level and acceptance of mother, and increase the vaccination rate of HPV vaccines.

Bawei Chenxiang Powder(BCP), first documented in the Tibetan medical work Four Medical Classics, has been widely applied in clinical practices in Tibetan and Mongolian medicines since its development. It has the effect of clearing the heart heat, calming the mind, and inducing resuscitation. On the basis of BCP, multiple types of formulae have been developed, such as Bawei Yiheyi Chenxiang Powder, Bawei Rang Chenxiang Powder, and Bawei Pingchuan Chenxiang Powder, which are widely used for treating cardiovascular and respiratory diseases. Current pharmacological research has revealed the pharmacological effects of BCP and its related formulae against myocardial ischemia, cerebral ischemia, renal ischemia, and anti-hypoxia. BCP and its related formulae introduced more treatment options for related clinical diseases and provided insights for fully comprehending the essence and pharmacological components of the formulae. This paper systematically reviewed the clinical and pharmacological research on BCP and its related formulae, analyzing the formulation principles and potential key flavors and active ingredients. This lays a fundamental scientific basis for the clinical use, quality evaluation, and subsequent development and application of BCP and its related formulae, providing references for studying traditional Chinese medicine formulae in a thorough and systematic manner.

The medicinal materials of Bawei Chenxiang Pills(BCPs) were extracted via three methods: reflux extraction by water, reflux extraction by 70% ethanol, and extraction by pure water following reflux extraction by 70% ethanol, yielding three extracts of ST, CT, and CST. The efficacy of ST(760 mg·kg~(-1)), CT(620 mg·kg~(-1)), and CST(1 040 mg·kg~(-1)) were evaluated by acute myocardial ischemia(AMI) and p-chlorophenylalanine(PCPA)-induced insomnia in mice, respectively. Western blot was further utilized to investigate their hypnosis mechanisms. The main chemical components of different extracts were identified by the UPLC-Q-Exactive-MS technique. The results showed that CT and CST significantly increased the ejection fraction(EF) and fractional shortening(FS) of myocardial infarction mice, reduced left ventricular internal dimension at end-diastole(LVIDd) and left ventricular internal dimension at end-systole(LVIDs). In contrast, ST did not exhibit significant effects on these parameters. In the insomnia model, CT significantly reduced sleep latency and prolonged sleep duration, whereas ST only prolonged sleep duration without shortening sleep latency. CST showed no significant effects on either sleep latency or sleep duration. Additionally, both CT and ST upregulated glutamic acid decarboxylase 67(GAD67) protein expression in brain tissue. A total of 15 main chemical components were identified from CT, including 2-(2-phenylethyl) chromone and 6-methoxy-2-(2-phenylethyl) chromone. Six chemical components including chebulidic acid were identified from ST. The results suggested that chromones and terpenes were potential anti-myocardial ischemia drugs of BCPs, and tannin and phenolic acids were potential hypnosis drugs. This study enriches the pharmacological and chemical research of BCPs, providing a basis and reference for their secondary development, quality standard improvement, and clinical application.

Gene regulation relies on the precise binding of transcription factors (TFs) at regulatory elements, but simultaneously detecting hundreds of TFs on chromatin is challenging. We developed cFOOT-seq, a cytosine deaminase-based TF footprinting assay, for high-resolution, quantitative genome-wide assessment of TF binding in both open and closed chromatin regions, even with small cell numbers. By utilizing the dsDNA deaminase SsdAtox, cFOOT-seq converts accessible cytosines to uracil while preserving genomic integrity, making it compatible with techniques like ATAC-seq for sensitive and cost-effective detection of TF occupancy at the single-molecule and single-cell level. Our approach enables the delineation of TF footprints, quantification of occupancy, and examination of chromatin influences on TF binding. Notably, cFOOT-seq, combined with FootTrack analysis, enables de novo prediction of TF binding sites and tracking of TF occupancy dynamics. We demonstrate its application in capturing cell type-specific TFs, analyzing TF dynamics during reprogramming, and revealing TF dependencies on chromatin remodelers. Overall, cFOOT-seq represents a robust approach for investigating the genome-wide dynamics of TF occupancy and elucidating the cis-regulatory architecture underlying gene regulation.
