Toosendanin (TSN) is a triterpenoid extracted from the bark or fruits of Melia toosendan Sieb et Zucc, which is a traditional Chinese medicine and mainly grows in China and India. TSN has been verified to possess antitumor activities on various human cancers, whereas the effects of TSN on ovarian cancer (OC) has not been reported yet. Here, TSN was shown to significantly inhibit proliferation of SKOV3 and OVCAR3 cell lines in a dose- and time-dependent manner. ⋯ Research on molecular mechanism indicated that the above efficacy of TSN was associated with decreased expression of survivin, PARP-1, Bcl-2, Bcl-xl, caspase-3, caspase-9, MMP-2 and MMP-9 and increased expression of cleaved PARP-1, Bax, cleaved caspase-3 and cleaved caspase-9. Finally, in vivo results showed that TSN suppressed OC xenograft tumor growth by inducing apoptosis and regulating the related protein expression levels of SKOV3 cells in transplanted tumors. Taken together, our data provide new insights into TSN as a potentially effective reagent against human OC through caspase-dependent mitochondrial apoptotic pathway.

Schisandra sphenanthera Rehd. et Wils (S. sphenanthera) is a single species of Schisandra genus, Magnoliaceae family, and it is a famous medicinal herb mostly growing in southern China, China Taiwan and Vietnam. S. sphenanthera is usually used for the treatments of hepatitis, Alzheimer's disease, renal transplantation, osteoporosis, and insomnia. ⋯ However, resource availability, quality control measures, in-depth in vivo pharmacological study, and clinical application are still insufficient and deserve further studies. This review systematically summarized literatures on the botany, phytochemistry, pharmacology, development utilization, and clinical application of S. sphenanthera, in hopes of provide a useful reference for researchers for further studies of this plant.

Review Meta Analysis
Efficacy and Safety of Chinese Herbal Medicine on Treatment of Breast Cancer: A Meta-analysis of Randomized Controlled Trials.
Breast cancer is currently the most common cancer in women, and it accounts for 11.6% of all cancer diagnoses in 2018. Breast cancer patients frequently resort to alternative medicine in addition to conventional Western therapy. This study is to evaluate clinical effectiveness of Chinese herbal medicine (CHM) on breast cancer by conducting meta-analyses on 81 randomized controlled trials (RCTs) with a total of 7215 subjects from eight databases. ⋯ Moreover, patients with complementary CHM therapy were associated with an mTTP of 2.79 months longer ([Formula: see text] < 0.00001) and an OS of 1.90 months longer ([Formula: see text] < 0.00001); they also had an increase in 3-year PFS ([Formula: see text]= 0.002), 2- ([Formula: see text]= 0.0002) and 5-year ([Formula: see text]= 0.006) OS rates. Therefore, complementary CHM therapy might demonstrate clinical benefits for breast cancer patients in terms of tumor response and survival. Clinical studies with further stratification of tumor stages and intervention types are highly warranted.

Patients with insomnia frequently use acupuncture as an alternative treatment to pharmacotherapy globally. The aim of this paper is to assess the effect of acupuncture on insomnia. Seven medical databases, including MEDLINE, EMBASE, CENTRAL, CNKI, RISS, NDSL, and OASIS, were used to identify studies published through July 09, 2020. ⋯ In the subsequent quantitative meta-analysis of studies comparing acupuncture versus pharmacotherapy, fifteen RCTs demonstrated that acupuncture had a significant effect on patients with insomnia as assessed by the Pittsburgh sleep quality index (PSQI) (RR: -0.74; 95% CI: -1.07 to -0.40; [Formula: see text] ¡0.0001; [Formula: see text] = 89%; [Formula: see text] = 1475). A subgroup analysis showed that there was no significant effect after weeks 1 and 2, but six studies found that acupuncture had a significant effect insomnia at week 3 (RR: -0.97; 95% CI: -1.65 to -0.28; [Formula: see text] = 0.006; [Formula: see text] = 91%; [Formula: see text] = 463) and nine studies demonstrated a significant effect at week 4 (RR: -0.70; 95% CI: -1.15 to -0.25; [Formula: see text] = 0.002; [Formula: see text] = 85%; [Formula: see text] = 594). These results suggest that insomnia patients may experience significant improvement in symptoms after more than three weeks of acupuncture treatment compared to pharmacological treatments.
