OBJECTIVE To investigate the effect of Huangqin decoction (HQD)-based self-assembled nanoparticles (SAN) co-loaded with terbinafine (TBF) (TBF-HQD-SAN NPs) on the transdermal absorption of TBF. METHODS High-speed centrifugation combined with dialysis was used to separate HQD-SAN, and TBF-HQD-SAN NPs were obtained by loading TBF using the ultrasound magnetic stirring method; the particle size distribution, Zeta potential and polydispersity index (PDI) of the nanoparticle were characterized, and the encapsulation efficiency (EE) and drug loading (DL) of TBF were determined; using in vitro and in vivo transdermal experiments, the differences in transdermal performance between TBF-HQD-SAN NPs and TBF raw materials, as well as TBF and HQD-SAN physical mixture (TBF-HQD-SAN PM), were compared and analyzed. RESULTS TBF- HQD-SAN NPs were spherical with a particle size of (177.60±2.57) nm, a PDI of 0.197 4±0.007 9, and a Zeta potential of (-14.63±0.85) mV. The EE and DL of TBF were (99.49±0.71)% and (3.22±0.10)% , respectively. In vitro transdermal experiments, compared with TBF raw materials, the steady-state permeation rate (Jss) and skin retention of TBF-HQD-SAN NPs increased by 3.34 times and 27.56 times, respectively (P<0.05); compared with TBF-HQD-SAN PM, its Jss and skinretention were increased by 2.04 times and 7.44 times, respectively (P<0.05). In vivo transdermal experiments 69号) showed that, the area under the drug-time curve and the maximum concentration of TBF-HQD-SAN NPs increased by 2.13 times and 2.06 times respectively compared to TBF raw materials, and increased by 1.59 times and 1.65 times respectively compared to TBF-HQD-SAN PM (P<0.05). CONCLUSIONS TBF-HQD-SAN NPs can significantly enhance the in vitro and in vivo transdermal absorption efficiency and skin retention of TBF.

In recent years, hybrid brain-computer interfaces (BCIs) have gained significant attention due to their demonstrated advantages in increasing the number of targets and enhancing robustness of the systems. However, Existing studies usually construct BCI systems using intense auditory stimulation and strong central visual stimulation, which lead to poor user experience and indicate a need for improving system comfort. Studies have proved that the use of peripheral visual stimulation and lower intensity of auditory stimulation can effectively boost the user's comfort. Therefore, this study used high-frequency peripheral visual stimulation and 40-dB weak auditory stimulation to elicit steady-state visual evoked potential (SSVEP) and auditory steady-state response (ASSR) signals, building a high-comfort hybrid BCI based on weak audio-visual evoked responses. This system coded 40 targets via 20 high-frequency visual stimulation frequencies and two auditory stimulation frequencies, improving the coding efficiency of BCI systems. Results showed that the hybrid system's averaged classification accuracy was (78.00 ± 12.18) %, and the information transfer rate (ITR) could reached 27.47 bits/min. This study offers new ideas for the design of hybrid BCI paradigm based on imperceptible stimulation.

Objective:This study aimed to analyze the genomic characteristics of Varicella-Zoster Virus (VZV) strains circulating in Jilin province from 2010 to 2023.Methods:Vesicle fluid from 78 sporadic cases with VZV infection were collected in Jilin province from 2010 to 2023, after detecting by Real-time PCR, 26 specimens (CT<25) were detected by PCR. Open reading frame 22(ORF22), ORF38 and ORF62 were amplified and analyzed. Genotyping was confirmed by SNPs ORF22 (37902, 38019, 38055, 38081 and 38177) and ORF38 (69424). Vaccine strains were indentified from wild-type strains according to ORF38 (69349) and ORF62 (106262, 107252, and 108111). Sequences were analyzed by homologous comparison and phylogenetic analysis.Results:The comparison with Dumas sequence revealed that SNPs (37902, 38055, 38081 and 38177) in ORF22 and ORF38 (69424) have mutations similar to the pOka strain, which belong to clade 2. Compared to the Dumas and Baike strains, all 26 samples were wild-type strains. JL2016-4 strain changes from threonine to asparaginyl at position 38059, JL2021-4 strain changes from arginine to proline at position 37933, from aspartic acid to tyrosine at position 37935, and from aspartic acid at base 38031 to tyrosine. JL2023-1 strain changes from arginine to leucine at position 37933.Conclusions:VZV has been prevalent for 14 years in Jilin province. The main epidemic strains belong to the clade 2. We should strengthen the monitoring of VZV outbreaks and raise the coverage rate of VZV vaccination.

ObjectiveTo develop traditional Chinese medicine (TCM) formulae for the treatment of nonsevere coronavirus disease 2019 (COVID-19) and to explore its anti-inflammatory mechanism. MethodsThe dysregulated signaling pathways were determined in macrophages from bronchoalveolar lavage fluid of COVID-19 patients and in lung epithelial cells infected with SARS-CoV-2 in vitro based on transcriptome analysis. A total of 102 TCM formulae for the clinical treatment of nonsevere COVID-19 were collected through literature. The pathway-reversing rates of these formulae in macrophages and lung epithelial cells were evaluated based on signature signaling pathways, and the basic formula was determined in conjunction with TCM theory. The commonly used Chinese materia medica for nonsevere COVID-19 were summarized from the 102 TCM formulae as abovementioned. And together with the screening results from the Pharmacopoeia of the People's Republic of China, a “Chinese materia medica pool” was esta-blished for the development of TCM formulae for COVID-19. The regulatory effects of each herb on signaling pathways were obtained based on targeted transcriptome analysis. Oriented at reversing dysregulated signaling pathways of COVID-19, the calculation was carried out, and the artificial intelligent methods for compositing formulae, that are exhaustive method and parallel computing, were used to obtain candidate compound formulas. Finally, with reference to professional experience, an innovative formula for the treatment of nonsevere COVID-19 was developed. The ethanol extract of the formula was evaluated for its anti-inflammatory effects by detecting the mRNA expression of interleukin 1b (Il1b), C-X-C motif chemokine ligand 2 (Cxcl2), C-X-C motif chemokine ligand 10 (Cxcl10), C-C motif chemokine ligand 2 (Ccl2), nitric oxide synthase 2 (Nos2), and prostaglandin-endoperoxide synthase 2 (Ptgs2) using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) in RAW264.7 cells treated with lipopolysaccharide (LPS). ResultsIn macrophages and lung epithelial cells, 34 dysregulated signaling pathways associated with COVID-19 were identified respectively. The effects of the 102 formulae for clinical treatment of nonsevere COVID-19 were evaluated based on the dysregulated signaling pathways and targeted transcriptome, and the result showed that Yinqiao Powder and Pingwei Powder (银翘散合平胃散, YQPWP) ranked first, reversing 91.18% of the dysregulated signaling pathways in macrophages and 100% of the dysregulated signaling pathways in lung epithelial cells. Additionally, YQPWP had the function of scattering wind and clearing heat, resolving toxins and removing dampness in accordance with the pathogenesis of wind-heat with dampness in COVID-19. It was selected as the basic formula, and was further modified and optimized to develop an innovative fomula Qiaobang Zhupi Yin (翘蒡术皮饮, QBZPY) based on expert experience and artificial intelligence in composing formulae. QBZPY can reverse all the dysregulated signaling pathways associated with COVID-19 in macrophages and lung epithelial cells, with the reversing rates of 100%. The chief medicinal of QBZPY, including Lianqiao (Fructus Forsythiae), Xixiancao (Herba Siegesbeckiae) and Niubangzi (Fructus Arctii), can down-regulate multiple signaling pathways related with virus infection, immune response, and epithelial damage. RT-qPCR results indicated that compared with the model group, the QBZPY group down-regulated the mRNA expression of Il1b, tumor necrosis factor (Tnf), Cxcl2, Cxcl10, Ccl2, Nos2 and Ptgs2 induced by LPS in RAW264.7 cells (P<0.05 or P<0.01). ConclusionBased on targeted transcriptome analysis, expert experience in TCM and artificial intelligence, QBZPY has been developed for the treatment of nonsevere COVID-19. The ethanol extract of QBZPY has been found to inhibit mRNA expression of several pro-inflammatory genes in a cellular inflammation model.
