It is believed that there is a pathogenesis of yang deficiency in polycystic ovary syndrome (PCOS) infertility, and it is concluded that warm-yang method has a better effect in improving endometrial abnormality, enhancing the quality of follicles, correcting endocrine disorders, and resolving or alleviating clinical symptoms in PCOS infertility. Based on Yanghe Decoction (阳和汤), a representative traditional Chinese medicine decoction for warming yang, Yanghe Xiaonang Decoction (阳和消囊汤) was formulated, combining with warm medicinals according to symptoms, and aerobic exercise was also advocated to help generate and develop yang qi, in order to provide ideas for clinical treatments.

Polycystic ovary syndrome(PCOS) and its resulting infertility is one of the common diseases of gynecology and reproductive endocrinology. The phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt) signaling pathway is relatively well-studied in the development of intervention in PCOS, and the experiments on PCOS in rats conducted by traditional Chinese medicine through this signaling pathway is also the main direction of mechanistic research. In this paper, 20 articles published in academic journals in the past 5 years were selected through the corresponding criteria, and the objective situation and existing problems of the selected research projects were analyzed from five aspects, namely, baseline data, modeling and treatment, grouping, evaluative indexes, and pharmacodynamic indexes. It is found that there were different degrees of problems in each research project, such as the observation indicators of modeling, criteria for judging the success of the model, the treatment period, the calculation of dosage of prescription/active ingredients and specific dosage were not clearly defined, which could easily lead the bias of the results or reduce the validity of experimental data. Based on this, the list of PCOS rat experimental research operations was formed, involving five categories of experimental rats, model construction, study implementation, outcome measures and analysis and report with a total of 21 operation lists, with a view to provide a reference for the subsequent PCOS experiments related to scientific research and helping to form high-quality results.

Platinum-based chemotherapy is used for non-small cell lung cancer (NSCLC). However, it has side effects and minimum efficacy against lung cancer metastasis. In this study, platinum-curcumin complexes were loaded into pH and redox dual-responsive nanoparticles (denoted as Pt-CUR@PSPPN) to facilitate intracellular release and synergistic anti-cancer effects. Pt-CUR@PSPPN was prepared by a nano-precipitation method and had a diameter of ∼100 nm. The nanoparticles showed increased anti-cancer effects both and . In addition, Pt-CUR@PSPPN blocked PI3K/AKT signal transduction pathway and inhibited MMP2 and VEGFR2, resulting in enhanced anti-metastatic activity. Furthermore, reduced side effects were also observed. In conclusion, Pt-CUR@PSPPN provided a novel and attractive therapeutic strategy for NSCLC.
