Chaihu Guizhi Ganjiangtang (CGG)is a classic prescription in the Treatise on Cold Damage,which has the effects of clearing and relieving stagnation heat in Shaoyang,warming and dissolving water drink,and relieving the pivot mechanism. It is a classic prescription for treating spleen deficiency and liver depression and stopping internal stagnation caused by water drink. The formula is exquisite and well-matched and is often modified and used by ancient and modern medical practitioners to treat various miscellaneous diseases of internal and external medicine,with significant therapeutic effects. In recent years,with the rapid development of modern pharmacology,research on the micro mechanism of CGG has been continuously developed and deepened,providing new ideas for the treatment of diseases with CGG. Therefore,the authors systematically searched databases such as China National Knowledge Infrastructure,Wanfang Data Knowledge Service Platform,VIP Database, and PubMed for literature on the clinical application and pharmacological mechanism of CGG published by Chinese and foreign scholars in recent years. This article summarized the literature from two aspects:the modern clinical application and mechanism of action of CGG and elaborated on the diseases treated by CGG in modern literature,involving digestive system,respiratory system,nervous system,endocrine system,circulatory system,urinary system,gynecology,as well as its application in reducing the side effects of radiotherapy and chemotherapy, gynecology, dermatology, ophthalmology, and orthopedics. At the same time,the mechanism of CGG in treating diseases may be related to anti-inflammatory,anti-oxidative stress, regulation of immunity, anti-fibrosis, anti-tumor, improvement of gastrointestinal flora and motility, protection of liver tissue, reduction of blood lipids and blood sugar, and regulation of hormone levels.

BACKGROUND:
The transcription factor POU2F1 regulates the expression levels of microRNAs in neoplasia. However, the miR-29b1/a cluster modulated by POU2F1 in gastric cancer (GC) remains unknown.
METHODS:
Gene expression in GC cells was evaluated using reverse-transcription polymerase chain reaction (PCR), western blotting, immunohistochemistry, and RNA in situ hybridization. Co-immunoprecipitation was performed to evaluate protein interactions. Transwell migration and invasion assays were performed to investigate the biological behavior of GC cells. MiR-29b1/a cluster promoter analysis and luciferase activity assay for the 3'-UTR study were performed in GC cells. In vivo tumor metastasis was evaluated in nude mice.
RESULTS:
POU2F1 is overexpressed in GC cell lines and binds to the miR-29b1/a cluster promoter. POU2F1 is upregulated, whereas mature miR-29b-3p and miR-29a-3p are downregulated in GC tissues. POU2F1 promotes GC metastasis by inhibiting miR-29b-3p or miR-29a-3p expression in vitro and in vivo . Furthermore, PIK3R1 and/or PIK3R3 are direct targets of miR-29b-3p and/or miR-29a-3p , and the ectopic expression of PIK3R1 or PIK3R3 reverses the suppressive effect of mature miR-29b-3p and/or miR-29a-3p on GC cell metastasis and invasion. Additionally, the interaction of PIK3R1 with PIK3R3 promotes migration and invasion, and miR-29b-3p , miR-29a-3p , PIK3R1 , and PIK3R3 regulate migration and invasion via the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway in GC cells. In addition, POU2F1 , PIK3R1 , and PIK3R3 expression levels negatively correlated with miR-29b-3p and miR-29a-3p expression levels in GC tissue samples.
CONCLUSIONS
The POU2F1 - miR-29b-3p / miR-29a-3p-PIK3R1 / PIK3R1 signaling axis regulates tumor progression and may be a promising therapeutic target for GC.

Triple-negative breast cancer (TNBC) remains a refractory subtype of breast cancer due to its resistance to various therapeutic strategies. In this study, we introduce a "brake-release and accelerator-pressing" approach to engineer a microneedle patch embedded with copper-doped Prussian blue nanoparticles (Cu-PB) and the ferroptosis inducer sorafenib (SRF) for raised chemodynamic (CDT)/photothermal (PTT) combination therapy against TNBC. Upon transdermal insertion, the dissolving microneedles swiftly disintegrate and facilitate the release of SRF. Under gentle external light exposure, copper ions (Cu2+) and iron ions (Fe3+) were liberated from Cu-PB. The direct chelation of Cu2+ and the indirect suppression by SRF, collectively attenuate glutathione peroxidase 4 (GPX4) enzymatic function, destabilizing the cellular redox equilibrium (referred to as the "brake-release" strategy). The release of Cu2+ and Fe3+ ions instigates a Fenton/Fenton-like reaction within tumor cells, further yielding hydroxyl radicals and elevating reactive oxygen species (ROS) concentrations (referred to as the "accelerator-pressing" strategy). This overwhelming ROS accumulation, coupled with the impaired clearance of resultant lipid peroxides (LPO), ultimately triggers a robust ferroptosis cell death response. In summary, this study presents an innovative combinatorial therapeutic strategy based on dual-ferroptosis induction for TNBC, implying a promising therapeutic platform for developing ferroptosis-centered treatments for this aggressive breast cancer subtype.

Objective:
To establish an optimized method for isolation and purification of microglia from aged rat brain tissue, and the phenotype of microglia was detected by flow cytometry.
Methods:
With young rats(3 months old) as control, the brain tissues of aged rats were immediately processed into single cell suspensions by mechanical dissociation and enzymatic digestion using type IV collagenase. Microglia were isolated on Percoll gradients(30%-37%-70%). The cells were stained with fluorescence-labeled antibodies and the phenotype of microglia was detected by flow cytometry.
Results:
This study developed a method that enzymatic digestion and mechanical dissociation combined with density gradient centrifugation. More single cells could be obtained by using this method. And the survival rate of cells was more than 90%. The flow cytometric analysis showed that the expression of M1 microglia marker CD86 and MHC Ⅱ increased(P<0.01), and the expression of M2 microglia marker CD200R increased(P<0.01) in aged rats compared with that in young rats.
Conclusion
The use of type IV collagenase and mechanical digestion combined with density gradient centrifugation is good for isolating and purifying microglia from adult and aged rat brain tissue.

With the process of China’s aging population intensifying, palliative care, as an important guarantee for improving the quality of life of terminally ill patients, is receiving more and more social attention, and the demand is constantly increasing. Palliative care needs versatile professionals, and general education can enhance people’s awareness and understanding of it, enabling more people to understand, accept, and participate in palliative care. With the advancement of knowledge and technology in palliative care, the traditional cramming education models are no longer able to meet the actual needs. Therefore, there is an urgent need to innovate palliative care education strategies. By analyzing the current problems in the general education of palliative care in China, this paper proposed thoughts and suggestions for general and innovative education of palliative care in several aspects, such as establishing general and innovative education systems and evaluation systems of palliative care, diversifying educational contents and methods, strengthening medical staffs training, promoting diversified student groups, and strengthening the popularization of palliative care knowledge among the public.

Objective:To explore the clinical phenotype and genetic basis of a child with Neutral lipid storage disease with myopathy (NLSDM).Methods:A child who was admitted to the First Affiliated Hospital of Zhengzhou University in February 2021 for a history of elevated creatine kinase (CK) for over 2 months was selected as the study subject. Clinical and laboratory examinations were carried out, and the child was subjected to whole exome sequencing. Candidate variants were validated by Sanger sequencing of her family members.Results:The patient, a 9-year-old female, had exhibited weakness in the lower limbs, elevated CK level, and refractory cardiomyotrophy. Genetic testing revealed that she has harbored c. 32C>G (p.S11W) and c. 516C>G (p.N172K) compound heterozygous variants of the PNPLA2 gene, which were respectively inherited from her mother and father. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were rated as likely pathogenic (PM1+ PM2_Supporting+ PP3+ PP4). Conclusion:The c. 32C>G (p.S11W) and c. 516C>G (p.N172K) compound heterozygous variants of the PNPLA2 gene probably underlay the myasthenia gravis and elevated creatine kinase in this child.

Objective:To explore the clinical characteristics and genetic etiology of a child with Spondyloocular syndrome (SOS) in order to enhance the awareness and understanding of this disease.Methods:A 3.5-year-old boy with SOS who had presented at the Department of Medical Genetics of Hunan Children′s Hospital on August 10, 2023 due to the repeated fractures for over 2 years and after binocular cataract surgery was selected as the study subject. Clinical data of his pedigree were collected, and peripheral venous blood samples were collected for the extraction of genomic DNA and subjected to trio-whole exome sequencing. Candidate variants were verified by Sanger sequencing and analyzed with bioinformatic software. This study was approved by the Medical Ethics Committee of Hunan Children′s Hospital (No. KYSQ2022-263).Results:The child had manifested repeated fractures, bilateral bowed femur, osteoporosis, cataract, atrial septal defect, and developmental delay. Ultrasonography has revealed fetal edema, peritoneal effusion, pleural effusion and polyhydramnios. Trio-whole exome sequencing and Sanger sequencing revealed that he has harbored compound heterozygous variants of the XYLT2 gene, namely c. 1103_1104delAG (p.Gln368Argfs*8) and c. 1238_1253delinsA (p.Val413_Pro418delinsGlu), which were inherited from his phenotypically normal father and mother, respectively. Neither variant was reported previously. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG) and recommendations from the Clinical Genome Resource (ClinGen), the c. 1103_1104delAG was predicted as a pathogenic variant (PVS1+ PM2_Supporting+ PP4), whilst the c.1238_1253delinsA was predicted as a likely pathogenic variant (PM4+ PM3+ PM2_Supporting+ PP4). Conclusion:The c. 1103_1104delAG and c. 1238_1253delinsA compound heterozygous variants of the XYLT2 gene probably underlay the pathogenesis in this child. Above finding has enriched the phenotypic and mutational spectrum of SOS, and provided a basis for the clinical diagnosis, treatment, prognosis assessment and genetic counseling for this pedigree.
