ObjectiveTo evaluate the therapeutic effect of stewed Polygoni Multiflori Radix on androgenic alopecia (AGA) and study the treatment mechanism. MethodNinety-nine SPF-grade male C57BL/6J mice were randomized into control, model, positive drug (finasteride, 0.65 mg·kg-1), low (0.78 g·kg-1), medium (1.56 g·kg-1), and high (3.12 g·kg-1)-dose stewed Polygoni Multiflori Radix, and Polygoni Multiflori Radix Praeparata groups by the random number table method. The mouse model of AGA was constructed by subcutaneous multi-point injection of testosterone propionate diluent for 60 days, and the mice were administrated with corresponding drugs by gavage from day 11. The therapeutic effects of stewed Polygoni Multiflori Radix and Polygoni Multiflori Radix Praeparata on AGA were evaluated by newly hair area, hair length, hair weight in the hair removal area, and hematoxylin-eosin staining. Enzyme-linked immunosorbent assay was employed to determine the levels of testosterone (T), dihydrotestosterone (DHT), and 5α-reductase (5-AR) in the skin tissue of mice. Western blot was employed to determine the expression levels of key proteins in the Wnt/β-catenin signaling pathway. ResultCompared with the control group, the model group (after 60 days of modeling) showed reductions in the newly hair area, hair length and weight in the back hair removal area, and ratio of hair follicles containing melanin to total hair follicles (P<0.05, P<0.01), elevated levels of T, DHT, and 5-AR, up-regulated expression level of glycogen synthase kinase-3β (GSK-3β) (P<0.05, P<0.01), and down-regulated expression levels of β-catenin, phospho-glycogen synthase kinase-3β (p-GSK-3β), and p-GSK-3β/GSK-3β (P<0.05, P<0.01) in the skin tissue. Compared with the model group, the positive drug, low-, medium-, and high-dose stewed Polygoni Multiflori Radix, and low-, medium-, and high-dose Polygoni Multiflori Radix Praeparata improved the newly hair area and hair length of mice (P<0.01), and stewed Polygoni Multiflori Radix and Polygoni Multiflori Radix Praeparata at low and medium doses improved the weight of newly formed hair in mice (P<0.05, P<0.01). The positive drug, low-, medium-, and high-dose stewed Polygoni Multiflori Radix, and low- and high-dose Polygoni Multiflori Radix Praeparata increased the ratio of hair follicles containing melanin to total hair follicles in the skin tissue (P<0.05, P<0.01). Compared with Polygoni Multiflori Radix Praeparata at the same doses, the medium and high doses of stewed Polygoni Multiflori Radix increased the ratio of melanin-containing hair follicles to total hair follicles (P<0.05). Compared with the model group, stewed Polygoni Multiflori Radix lowered the levels of T and DHT, down-regulated the expression level of GSK-3β (P<0.01), and up-regulated the expression levels of β-catenin, p-GSK-3β, and p-GSK-3β/GSK-3β (P<0.05, P<0.01) in the skin tissue of the mice. ConclusionStewed Polygoni Multiflori Radix can ameliorate androgenic alopecia in mice by reducing the androgen level and promoting Wnt/β-catenin signaling.

Institutions of higher education undertake a significant number of animal experiment projects with diverse types. To standardize animal experiments and ensure animal welfare, ethical review has become a core task for the Institutional Animal Care and Use Committee (IACUC) in these higher education institutions. A key issue worth exploring is how to improve the efficiency of animal ethical reviews while maintaining systematic quality of supervision. Based on the current status of ethical reviews at the Laboratory Animal Center of Huazhong University of Science and Technology, this paper designs and implements a full-process ethical review software system. This system seeks to offer solutions for the ethical review and supervision of animal welfare in institutions of higher education through information technology. The system employs a full-process supervision philosophy of "pre-approval, in-process supervision, post-review," focusing on strengthening the review and approval of animal research protocols, as well as post-approval monitoring. At the pre-approval stage, the system optimizes the process for designated members involved in the project review, ensuring that all projects comply with ethical standards and legal regulations. At the in-process stage, veterinary verification and consultation are carried out by executive veterinarians, using a method of "offline inspections and online records" for supervision. At the post-review stage, researchers are required to provide retrospective data to evaluate the experimental process. Additionally, this paper provides an in-depth exploration of the software, detailing its functional and non-functional requirements, as well as its security considerations. It also delves into the comprehensive software architecture, process design, and operational details. Furthermore, it illustrates the system's operational efficacy and impact since its launch. This paper discusses the software's applicability and practicality, analyzing existing limitations and challenges, such as the difficulty of balancing experiment urgency with the stringent nature of review processes, and the traceability blind spots in post-approval supervision. Future research will continue to enhance the accuracy and strength of animal welfare ethical reviews and supervision through new technologies and methods.

Objective:To explore the prenatal ultrasound phenotype and genetic basis of two fetuses with Wolf-Hirschhorn syndrome (WHS).Methods:A retrospective analysis was conducted on the ultrasound imaging data of two fetuses suspected for WHS at the Prenatal Diagnostic Center of Qingyuan People′s Hospital in July 2017 and August 2019, respectively. Amniotic fluid samples of the two fetuses were subjected to chromosomal karyotyping and chromosomal microarray analysis (CMA). This study was approved by Medical Ethics Committee of the Qingyuan People′s Hospital (Ethics No. IRB-2022-064).Results:Prenatal ultrasound examination of the two fetuses had consistently revealed WHS-associated traits including intrauterine growth restriction (IUGR), craniofacial abnormalities and cardiovascular anomalies. Karyotyping analysis suggested that both fetuses had harbored cryptic chromosomal translocations involving partial deletion of 4p. And parental verification revealed that it was de novo for fetus 1 and paternal for fetus 2. CMA has confirmed that fetus 1 had an approximately 8.7 Mb deletion at 4p16.3p16.1 and a 6.8 Mb duplication at 8p23.1p23.1, whilst fetus 2 had a 20.05 Mb deletion at 4p16.3p15.31 and a 7.66 Mb duplication at 9p24.3p24.1. The karyotype of fetus 1 was determined as 46, XN, der(4)t(4; 8)(p16.1; p23.1)dn.arr[hg19]4p16.3p16.1(68345_8721580)×1, 8p23.3p23.1(158048_6933745)×3, and that of fetus 2 was determined as 46, XN, der(4)t(4; 9)(p15.3; p24)dpat.arr[hg19]4p16.3p15.31(68345_20116061)×1, 9p24.3p24.1(208454_7868292)×3. Conclusion:The 4p deletion is probably the main cause for the WHS phenotype in both fetuses. WHS should be suspected when IUGR, renal anomalies, craniofacial and cardiovascular abnormalities are detected upon prenatal ultrasound screening.

Background:
SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood.
Methods:
We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival.
Results:
Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity.
Conclusions
The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

Malignancies are diseases resulting from an imbalance of cell growth and proliferation, endangering human health and life. Currently, there is no clinically effective treatment for tumors. Tumor cells may alter cell adhesion and tumor cell migration and movement by degrading the extracellular matrix, generating vascular factors, affecting epithelial-mesenchymal transformation, or altering the tumor microenvironment. The mechanisms which lead to multidrug resistance (MDR) are the regulation of membrane proteins, apoptosis-regulated gene expression, enzyme-mediated multidrug resistance, DNA damage repair, and epithelial-stromal transformation, resulting in ineffective treatment of tumors. Therefore, the search for natural, safe, and effective chemosensitizers has become a critical part in tumor research. Due to the increasing use of Chinese medicine in cancer treatment, researchers have conducted more extensive studies on its monomers and compounds. In addition, the mechanisms of Chinese medicine in inhibiting tumor invasion and metastasis and reversing drug resistance are gradually unraveled. The monomers and compounds of Chinese medicine may inhibit tumor invasion, metastasis, and drug resistance by enhancing the sensitivity of chemotherapy drugs and adjuvant properties. Furthermore, they can also improve the tolerance of patients to chemotherapy drugs, relieve side effects of chemotherapy, reduce the chance of recurrence, and prolong the life of patients. The development of traditional Chinese medicine plays an important role in reducing tumor recurrence and metastasis, reversing drug resistance, prolonging the prognosis of cancer patients, improving their quality of life, and prolonging their survival time. Currently, various types of Chinese medicines have been proven to be capable of reducing tumor invasion and metastasis, and reversing drug resistance. The present article reviewed development and findings of Chinese medicine as an anti-tumor invasion, anti-metastasis, and anti-tumor resistance therapy in recent years, in order to provide ideas for future research on anti-tumor effect of active components in Chinese medicine.
