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.

As a representative prescription of stagnated blood syndrome,Didang Decoction has the effect of breaking blood,removing blood stasis and purging heat.According to the pathogenesis characteristics of"blood stasis and heat accumulation",Didang Decoction has been widely used in the treatment of diabetes and its complications,cerebrovascular diseases,gynecology and andrology and other diseases.This article summarized the effects of factors such as drug compatibility,processing methods and decocting time on the chemical components of Didang Decoction,and concluded its pharmacological effects from the aspects of improving insulin resistance,antioxidation,regulating cell death,anti-inflammatory,anti-tumor,anti fibrosis,anticoagulation,reducing toxicity of Gelsemium elegans,regulating blood lipid metabolism,and improving microcirculation,providing references for the research and clinical application of Didang Decoction.

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.

Objective To elucidate the immunologic mechanism and clinical effect of high intensity focused ultrasound (HIFU) combined with dendritic cell and cytokine induced killer cell (DC-CIK) immunotherapy on patients with pancreatic cancer.Methods Seventy-two pancreatic cancer patients were divided randomly into 2 equal groups,one treated with HIFU only the other treated with HIFU and DC-CIK immunotherapy.Ultrasound imaging and a variety of immunological indexes were recorded before and after treatment and the clinical effects in the two groups were compared.Moreover,autogenous tumor cells were isolated from the combination therapy group and the killing activity of DC-CIK which loaded tumor antigen processed by HIFU on autogenous tumor cells was observed.Results Tumor antigen processed by HIFU can improve the killing activity of DC-CIK on autogenous tumor cells.After treatment,the immunological indexes,of all patients were better than before treatment.(58.26 ± 17.97 versus 52.15 ± 14.22 pg/ml with IL-12 22.14 ± 6.39 versus 17.36 ± 5.73 ng/ml with HSP70 and 0.94 ± O.34 versus 1.32 ± O.61 ng/ml with TGF-β,P ＜ 0.05 ) ; The combination group was significantly better than the HIFU group with regard to the average scores of quality of life (75.89 ± 19.65 versus 67.22 ± 16.34,P＜0.05),pain (3.15 ±0.82 versus 3.59 ± 1.04,P ＜0.05),tumor markers (107.55 ±27.58 versus 123.63 ±34.12 U/ml) and survival time (18.92±6.47 versus 13.36 ±5.78 mos).Conclusion HIFU can improve the immunologic status and anti-tumor response in patients with pancreatic cancer.HIFU combined with DC-CIK has good synergistic therapeutic effect for treating pancreatic cancer.
