RESUMEN
Objective:To explore the effects of acupuncture combined with Buyang Huanwu Decoction on intestinal flora in cerebral blood flow hypo perfusion model rats with carotid artery stenosis.Methods:Totally 40 rats were randomly divided into sham-operation group, model group, TCM treatment group and acupuncture and drug combination treatment group, with 10 rats in each group. Except the sham-operation group, the other groups were prepared cerebral ischemia model by needle control and thread embolism method. TCM treatment group received Buyang Huanwu Decoction 100 mg/kg for gavage, once a day, and the intervention lasted for 2 weeks. In the acupuncture and drug combination group, based on the TCM treatment group, Baihui and its left and right sides of 2 mm were selected for acupuncture, once a day, and continuous intervention was performed for 2 weeks. Neurological function evaluation and behavioral function score were performed 7 and 14 days after administration, respectively. 16S rRNA sequencing was used to comprehensively characterize the structure and composition of fecal microflora of rats in each group. Linear discriminant analysis Effect Size (LEfSe) was used to analyze the difference of intestinal bacteria among groups.Result:On the 7th and 14th day after administration, compared with the model group, the neurological function score in the TCM treatment group and the acupuncture and drug combination group decreased ( P<0.05), and the behavioral function score increased ( P<0.05). Compared with model group, the Shannon index of TCM treatment group and acupuncture and drug combination group increased ( P<0.05). The abundance of Firmicutes increased ( P<0.05), and the abundance of Bacteroidetes and Proteobacteria decreased ( P<0.05); the abundance of Clostridia increased ( P<0.05), and the abundance of Gammaproteobacteria decreased ( P<0.05). The abundance of Escherichia-Shigella and Bacteroides decreased ( P<0.05); the abundance of lactobacillus significantly increased ( P<0.05). Conclusion:Acupuncture combined with Buyang Huanwu Decoction can improve the symptoms of cerebral hypoperfusion model rats with carotid artery stenosis, and the mechanism may be to increase the abundance of probiotics.

RESUMEN
The SARS-CoV-2 virus is the causal agent of the ongoing pandemic of coronavirus disease 2019 (COVID-19). There is an urgent need for potent, specific antiviral compounds against SARS-CoV-2. The 3C-like protease (3CLpro) is an essential enzyme for the replication of SARS-CoV-2 and other coronaviruses, and thus is a target for coronavirus drug discovery. Nearly all inhibitors of coronavirus 3CLpro reported so far are covalent inhibitors. Here, we report the development of specific, non-covalent inhibitors of 3CLpro. The most potent one, WU-04, effectively blocks SARS-CoV-2 replications in human cells with EC50 values in the 10-nM range. WU-04 also inhibits the 3CLpro of SARS-CoV and MERS-CoV with high potency, indicating that it is a pan-inhibitor of coronavirus 3CLpro. WU-04 showed anti-SARS-CoV-2 activity similar to that of PF-07321332 (Nirmatrelvir) in K18-hACE2 mice when the same dose was administered orally. Thus, WU-04 is a promising drug candidate for coronavirus treatment. One-Sentence SummaryA oral non-covalent inhibitor of 3C-like protease effectively inhibits SARS-CoV-2 replication.
