Erectile dysfunction （ED） is a common chronic andrological disease that seriously impairs men’s physical and mental health and reduces their quality of life. Shugan yiyang capsule is a compound formula of traditional Chinese medicine for the clinical treatment of erectile dysfunction， with core effects of soothing the liver， relieving depression， promoting blood circulation， and nourishing the kidneys. This paper systematically reviewed the mechanisms of action and clinical research progress of Shugan yiyang capsule in the treatment of ED. Accumulated evidence indicated that this capsule exerted its therapeutic effects by modulating signaling pathways such as nitric oxide synthase/cyclic guanosine monophosphate and phosphoinositide 3-kinase/protein kinase B， inhibiting phosphodiesterase-5 （PDE-5） expression and oxidative stress， regulating hypothalamic-pituitary-testicular axis function， and improving penile hemodynamics. In terms of clinical application， Shugan yiyang capsule used alone improved erectile function and related clinical indicators in patients with ED. When combined with PDE-5 inhibitors or surgical operation， Shugan yiyang capsule also demonstrated certain synergistic and efficacy-enhancing effects， with generally good tolerability. However， existing studies were still limited by insufficient investigation of the pharmacodynamic material basis of the formula， inadequate elucidation of the interactions among different signaling pathways， a lack of direct experimental validation for some potential mechanisms， and relatively small sample sizes and limited levels of clinical evidence. Future studies will integrate serum pharmacochemistry， multi-omics approaches， and pharmacokinetic techniques to further characterize the absorbed constituents， key pharmacologically active components， and multi-target synergistic mechanisms of Shugan yiyang capsule. Meanwhile， multicenter， large-sample randomized controlled trials with long-term follow-up will be conducted to strengthen the quality of clinical evidence and facilitate the precise use of Shugan yiyang capsule in the treatment of ED.

Varicocele-induced infertility(VCI)is a common andrological disease in clinical practice.Oxidative stress represents the primary mechanism through which varicocele causes male infertility.Traditional Chinese medicine(TCM)treatment,characterized by its multi-target,multi-component,multi-system,and multi-pathway actions,has achieved favorable outcomes in the field of VCI treatment.This paper summarizes the underlying oxidative stress mechanism of VCI and the relevant signaling pathways involved.By reviewing the current research status on how monomers,active fractions,compound formulas,and related preparations of TCM can intervene in oxidative stress through the regulation of these signaling pathways to improve VCI,it is found that the nuclear factor-erythroid 2-related factor 2(Nrf2)signaling pathway,the mitogen-activated protein kinase(MAPK)signaling pathway,and the hypoxia-inducible factor-1α(HIF-1α)signaling pathway are closely related to the development of VCI.TCM monomers and active fractions(flavonoids from Cuscutae Semen,polysaccharides from Astragali Radix,curcumin,ginsenoside Rg1,hyperin and echinacoside),as well as compound formulas and related preparations of TCM(modified Dahuang zhechong granules,Shengjing huoxue formula,modified Tianxiong san,Tongjingling,Bushen huoxue formula,Mailuoshutong pill,Zishen yutai pill,Danhong tongjing formula)can alleviate oxidative stress,reduce lipid peroxidation damage,improve mitochondrial dysfunction,decrease sperm DNA fragmentation,and inhibit apoptosis by activating the Nrf2 signaling pathways and inhibiting the MAPK and HIF-1α signaling pathways,thereby improving reproductive function.

The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.

Objective:To delineate a deletional mutation of the HLA-B gene in a Chinese pedigree.Methods:A female patient with acute myeloid leukemia who had visited Liuzhou People′s Hospital in April 2022 was selected as the study subject. Routine human leukocyte antigen (HLA) was determined by using PCR-sequence specific oligonucleotide polymorphism (PCR-SSOP) and PCR-sequence-based typing (PCR-SBT) methods. Next generation sequencing (NGS) was used to validate the candidate variant in the HLA-B gene.Results:The PCR-SBT and SSOP results for the HLA-B locus were inconsistent for the patient and her daughter. The SSOP results of the two individuals were HLA-B*35: 01, 40: 02 and HLA-B*35: 01, 40: 01, respectively. However, the PCR-SBT results has indicated a mismatch with the nearest HLA-B*35: 01 at exon 4. NGS results showed that the HLA-B*35: 01 had a 9 bp deletion in the intron 5. The patient′s husband was HLA-B*40: 01, 58: 01, which was normal. Conclusion:The variant in intron 5 of the HLA-B gene in this pedigree has mapped to a primer-binding region for the SBT reagent, which has affected the accuracy of PCR-SBT results.
