This paper reported the clinical manifestations, pathological features, immunophenotype and follow-up of two patients with superficial CD34-positive fibroblastic tumor (SCPFT), who were admitted to Shandong Provincial Hospital in 2022 and 2023, and discussed the relevant literatures. The two patients, aged 43 and 20 years old, were both male. Their tumors were located in the perineum and the back of left shoulder, respectively. Both presented as single slow-growing subcutaneous masses with a course typically measured in years, accompanied by mild tenderness but without pain or pruritus. Microscopically, spindled to epithelioid cells and pleomorphous nuclear cells arranged in cellular fascicles and solid sheets were the main findings. Immunophenotypically, positive expression of CD34 was found in both cases. Extended resection ensured negative marginal and basal margins for both cases. No recurrence was observed after 22 and 12 months of follow-up, respectively. Clinical features, pathology, and differential diagnosis were discussed and summarized through a review of relevant literature. SCPFT is a novel type of fibroblastic tumor categorized as a low-grade malignant soft tissue tumor with unique pathological and biological characteristics that is relatively rare clinically. Routine resection may lead to recurrence; therefore, long-term follow-up is necessary. The combination of morphological characteristics and immunohistochemistry is helpful to diagnosis. It is important to differentiate this disease from other tumors to avoid misdiagnosis or mistreatment.

Excessive ionizing radiation can disrupt the molecular structures of organisms,leading to health issues such as acute radiation syndrome and cancer,posing serious threats to human health.The development of radioprotective drugs holds significant importance for mitigating ionizing radiation damage and safeguarding public health,yet its research process faces multidimensional ethical challenges.This paper systematically explores the ethical issues involved in the full lifecycle of radioprotective drug development,focusing on the ethical particularities of animal experimentation,ethical dilemmas in human trials,data privacy and security risks,as well as challenges in managing conflicts of interest.Targeted solutions are proposed,including strengthening ethical review mechanisms,promoting interdisciplinary collaboration,constructing data security management systems,and establishing conflict-of-interest mediation mechanisms.These comprehensive measures aim to build a scientifically rigorous ethical framework for radioprotective drug research,fostering sustainable development in this field.

Objective To explore the role of clinical pharmacists in the treatment of advanced breast cancer patients with severe myelosuppression.Methods This case report describes the diagnostic and therapeutic process of an advanced breast cancer patient who developed severe myelosuppression after applying ADC-based drug therapy.The clinical pharmacist proposed a prophylactic antimicrobial drug selection plan and medication monitoring recommendations for the patient's granulocytopenic fever after assessing the risk of infection and liver and renal function.For oncology drug-associated thrombocytopenia,when the doctor proposed to use the recombinant human thrombopoietin combined with TPO agonists in the case of the ineffectiveness of conventional treatment,the clinical pharmacist searched for the pharmacological basis of the combination regimen,the clinical studies of the efficacy and the adverse reactions to assist the physician's decision-making and provided targeted medication monitoring of the patient.Results The clinician and clinical pharmacist developed and implemented a rational treatment plan,and the patient was discharged with improvement.Conclusions Clinical pharmacists can assist physicians in optimizing individualized treatment plans through pharmacological monitoring of advanced breast cancer patients with severe myelosuppression.This collaborative treatment model can provide patients with more individualized treatment;it can also provide clinical reference to the treatments of patients with severe myelosuppression.

Objective:To investigate the role of YTHDF2 in cervical lesions and its potential molecular mechanism.Methods:Gene expression data of cervical tissue were obtained from the GEO database to analyze the expression of YTHDF2 mRNA and perform pathway enrichment analysis. Patients with cervical lesions diagnosed by thinprep cytologic test in Gynecological Outpatient Department of Maternal and Child Health Hospital in Jiexiu, Shanxi Province, were selected as the research subjects. Data of cervical lesions and cervical exfoliated cells were collected. HPV infection status was detected by flow-through hybridization, and the expression of YTHDF2 mRNA was detected by reverse transcription real-time polymerase chain reaction. The expression of YTHDF2 in cervical lesions and the mediating role of HPV infection in the relationship between YTHDF2 and squamous intraepithelial lesion (SIL) were evaluated. YTHDF2-related genes were screened from multiple datasets in the GEO and ENCORI databases, and their expression, immune infiltration, and survival analysis were performed to assess the association between YTHDF2 and prognosis. Results:Compared with normal cervical tissue, YTHDF2 was highly expressed in cervical lesion tissue ( P<0.05). A total of 3 672 differentially expressed genes were screened from the dataset GSE49339. Gene Ontology analysis showed that YTHDF2 was mainly involved in transcription regulation. Kyoto Encyclopedia of Genes and Genomes analysis showed that YTHDF2 might be related to HPV infection and other signaling pathways. In the mediation analysis, χ2 test results showed that the expression level of YTHDF2 was significantly different among groups ( χ2=22.47, P<0.001). Trend χ2 test further showed that the expression level of YTHDF2 was upregulated with the degree of cervical precancerous lesions (trend χ2=10.26, P=0.001). Multivariate logistic regression analysis indicated that high YTHDF2 expression increased the risk of low-grade squamous intraepithelial lesions ( OR=3.15, 95% CI: 1.93-5.15) and high-grade squamous intraepithelial lesions ( OR=1.85, 95% CI: 1.01-3.39). Mediation effect analysis revealed a partial mediating effect of HPV infection between YTHDF2 and SIL, accounting for 32.02% of the total effect. Twelve YTHDF2 related genes were screened by the intersection of multiple datasets. The immune infiltration analysis results showed that YTHDF2 and related genes KLF4, E2F3 and HOXC6 were associated with immune infiltration (all P<0.05). Multivariate Cox proportional hazard regression model analysis showed that low expression of KLF4 ( HR=0.53, 95% CI: 0.30-0.94) and high expression of RHOB ( HR=1.80, 95% CI: 1.04-3.13) were risk factors for the prognosis of cervical cancer. Conclusion:YTHDF2 is highly expressed in cervical lesions and may have been involved in the regulation of HPV infection-related pathways and its downstream related genes are related to immune infiltration and prognosis of cervical cancer, providing a theoretical basis for the study of mechanisms related to cervical lesions.

Post-stroke spasticity is a series of symptoms after stroke,such as hand and foot urgency,unflexion and extension of muscles,etc.In order to deeply understand the cognition of post-stroke spasticity of ancient Chinese physicians and comb out their therapeutic thoughts,this study took the General Catalogue of Chinese Ancient Books of Traditional Chinese Medicine as a bibliographic reference,all the ancient Chinese literature on spasms after stroke was retrieved manually and by computer,and then sorted and analyzed,and classified them by longitudinal time,and extracted the description about post-stroke spasticity,including medical classics,prescriptions,clinical evidence,medical records and so on.And this paper verified and summarized the etiology,pathogenesis,functional and indications and prescription characteristics of spasticity after stroke,in order to deeply understand systematic theories and treatment ideas of the ancient medical practitioners in the bud,development and mature stages of their understanding of spasticity after stroke,and provide the theoretical basis for the later doctors to understand this disease and the modern clinical treatment of traditional Chinese medicine.
