RESUMO
Chronic obstructive pulmonary disease (COPD) is one of the major diseases threatening human life and health. According to the report released by the World Health Organization (WHO) in 2020, COPD has become the third leading cause of death in the world, featuring a sustainable growth of incidence rate as well as population age. The purpose of this review focuses on the advancement of bioactive natural compounds, such as baicalin, quercetin, resveratrol, and curcumin, which demonstrate promising therapeutic/interventional effects on CODP in vitro and in vivo. Information emphasizing on COPD was systematically collected from several authoritative internet databases including Web of Science, PubMed, Elsevier, Wiley Online Library, and Europe PMC, with a combination of keywords containing "COPD" and "natural small molecular compounds". The new evidence indicated that these valuable molecules featured unique functions in the treatment of COPD through various biological processes such as anti-inflammatory, anti-oxidant, anti-apoptosis, and anti-airway fibrosis. Moreover, we found that the promising effects of these natural compounds on COPD were mainly achieved through JAK3/STAT3/NF-κB and MAPK inflammatory signaling pathways, Nrf2 oxidative stress signaling pathway, and TGF-ß1/Smad 2/3 fibrosis signaling pathway, which referenced to multiple targets like TNF-α, IL-6, IL-8, TIMP-1, MMP, AKT, JAK3, IKK, PI3K, HO-1, MAPK, P38, ERK, etc. Current challenges and future directions in this promising field are also discussed at the end of this review. For the convenience of the readers, this review is divided into ten parts according to the structures of potential natural small molecular compounds. We hope that this review brings a quick look and provides some inspiration for the research of COPD.
RESUMO
The clinical efficacy of Bushen Huoxue traditional Chinese medicine( TCM) in the treatment of hyperprolactinemia were systematically evaluated,which provided evidence-based medical evidence for the treatment of hyperprolactinemia with Bushen Huoxue traditional Chinese medicine. The randomized controlled trials on the treatment of hyperprolactinemia with Bushen Huoxue traditional Chinese medicine were comprehensively searched by computer in PubMed,EMbase,Cochrane Library,CNKI,Wan Fang,VIP,CBM and Meta-analysis was performed. The search time is from the time of self-built database to September 28,2018. A total of 816 patients with hyperprolactinemia met the inclusion criteria in 13 clinical studies. The results of Meta-analysis showed that compared with Western medicines,traditional Chinese medicine for tonifying kidney and activating blood circulation had a comparable effect in reducing prolactin and treating infertility,and had obvious advantages in improving of TCM syndromes,disease recurrence and reducing of side effects.

Meta-analysis of randomized controlled trials( RCTs) was conducted to clarify the effect of Bushen Huoxue herbal medicine in subfertile women with polycystic ovary syndrome. Databases including CNKI,Wan Fang,VIP,Sino Med,PubMed,EMbase,the Cochrane Library were searched until September,2018. Two reviewers independently assessed study eligibility,extracted data,and evaluated the risk of bias for included trials. Meta-analysis used Review Manager 5. 3 software. Seven RCTs( n = 634) were included.RESULTS: of Meta-analysis indicated that,Bushen Huoxue herbal medicine had advantages on increasing pregnancy rate,lowering LH,T and INS. Bushen Huoxue herbal medicine were not clear on increasing ovulation rate,increasing FSH. No serious adverse reaction appearing from Bushen Huoxue herbal medicine was reported in the including researches. The current Meta-analysis showed a promising effect of Bushen Huoxue herbal medicine in subfertile women with polycystic ovary syndrome,but the quality of current evidence was low and possible publication bias.

Potential xanthine oxidase (XOD) inhibitors in Lagotis brevituba were captured by using affinity and ultrafiltration. The structures of the captured components were identified by ultra-performance liquid chromatography coupled with Q-TOF mass spectrometry (UPLC-Q-TOF-MS). The binding intensity and binding mechanism between the captured components and XOD were analyzed by using molecular docking software Autodock 4.2. A total of 17 compounds were identified, including 9 flavonoids, 5 phenolic acids and 3 triterpenes. Molecular docking results showed that all the captured components could be spontaneously bound with XOD mainly via hydrogen bond, Van der Waals' force and hydrophobic interaction. From the perspective of binding energy and scoring function, the collected fractions all had potential prospects for XOD inhibitors, and the flavonoid luteolin-3',7 glucuronide had the best effect. The results also showed that affinity and ultrafiltration, ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) and molecular docking technology can provide a powerful tool for the analysis of XOD inhibitor components in natural products.
