Objectives: This study aimed to investigate the impact of coronavirus disease 2019 (COVID-19) on admission rates and in-hospital mortality among patients with ischemic and hemorrhagic stroke. Methods: We constructed a dataset detailing the monthly hospitalizations and mortality rates of inpatients with stroke from January 2017 to December 2021. Employing an interrupted time series analysis, we explored the impact of COVID-19 on hospitalizations and 30-day in-hospital mortality among stroke patients. Results: The number of ischemic stroke admissions decreased by 18.5%, from 5335 to 4348, immediately following the COVID-19 outbreak (p<0.001). The in-hospital mortality rate for ischemic stroke increased slightly from 3.3% to 3.4% immediately after the outbreak, although it showed a decreasing trend over time. The number of hemorrhagic stroke admissions fell by 7.5%, from 2014 to 1864, immediately following the COVID-19 outbreak. The 30-day in-hospital mortality rate for hemorrhagic stroke initially decreased from 12.9% to 12.7%, but subsequently showed an increasing trend. Conclusions We confirmed that COVID-19 impacted both the admission and death rates of stroke patients. The admission rate for both ischemic and hemorrhagic strokes decreased, while in-hospital mortality increased. Specifically, in-hospital mortality from ischemic stroke rose initially after the outbreak before stabilizing. Additionally, our findings indicate variable effects based on sex, age, and socioeconomic status, suggesting that certain groups may be more susceptible. This underscores the need to identify and support vulnerable populations to mitigate adverse health outcomes.

The main chemical components of Allii Macrostemonis Bulbus and components in serum were analyzed and identified rapidly and precisely by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS)technique in this study.The compounds were identified based on the relative molecular mass,fragmentation ions,and retention time of chromatographic peaks.A total of 36 kinds of chemical components were identified from Allii Macrostemonis Bulbus,including 28 kinds of saponins,3 kinds of amino acids,2 kinds of flavonoids,one kind of organosulfur compound,one kind of nucleoside,and one kind of hormone-lipid compound.In addition,8 kinds of compounds of Allii Macrostemonis Bulbus were identified from the serum.Based on the intersection compounds of which detected in serum and screened out by TCMSP platform database,by using targeted network pharmacology and molecular docking technology,a"drug-component-target-pathway"association network was constructed.Naringenin,quercetin,macrostemonoside E and 25(R)-26-O-β-D-glucopyranosyl-22-hydroxy-5β-furostan-3-O-β-D-glucopyranosyl(1→2)-β-D-glucopyranoside were screened as the main active constituents of Allii Macrostemonis Bulbus in the treatment of hyperlipidemia.In addition,adenosine 5′-monophosphate-activated protein kinase(AMPK),tumor necrosis factor(TNF),vascular endothelial growth factor A(VEGFA)and matrix metallopeptidase 9(MMP9)were the key action targets for Allii Macrostemonis Bulbus in the treatment of hyperlipidemia.Molecular docking was performed using the main pharmacodynamic components and key action targets.The results indicated that all the four active components showed strongly bound to AMPK.This suggested that the regulation of lipid metabolism might be the key mechanism of Allii Macrostemonis Bulbus in antihyperlipidemic effect.This study provided a data reference for the research on the pharmacodynamic components of Allii Macrostemonis Bulbus,and provided a basis for the improvement of quality standard of Allii Macrostemonis Bulbus.

An analytical method for 10 mycotoxins in Hippophae Fructus medicinal and edible products was established in this study, and the contamination of their mycotoxins was analyzed. First of all, the mixed reference solution of ten mycotoxins such as aflatoxin, ochratoxin, zearalenone, and dexoynivalenol was selected as the control, and the Hippophae Fructus medicinal and edible products were prepared. Secondly, based on the ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) technology, 10 mycotoxins in Hippophae Fructus medicinal and edible products were quantitatively investigated and their content was determined. Finally, the contamination of mycotoxins was analyzed and evaluated. The optimal analysis conditions were determined, and the methodological inspection results showed that the 10 mycotoxins established a good linear relationship(r>0.99). The method had good repeatability, test sample specificity, stability, and instrument precision. The average recovery rates of 10 mycotoxins in Hippophae Fructus medicinal products, edible solids, and edible liquids were 90.31%-109.4%, 87.86%-107.8%, and 85.61%-109.1%, respectively. Relative standard deviation(RSD) values were 0.22%-10%, 0.75%-13%, and 0.84%-8.5%, repsectively.

The PRR11 gene (Proline Rich 11) has been implicated in lung cancer; however, relationship between PRR11 and immune infiltration is not clearly understood. In this study, we used The Cancer Genome Atlas (TCGA) data to analyze the lung adenocarcinoma patients; PRR11 gene expression, clinicopathological findings, enrichment, and immune infiltration were also studied. PRR11 immune response expression assays in lung adenocarcinoma (LUAD) were performed using TIMER, and statistical analysis and visualization were conducted using R software. All data were verified using Gene Expression Profiling Interactive Analysis (GEPIA), and the Human Protein Atlas (HPA). We found that PRR11 was an important prognostic factor in patients with LUAD. PRR11 expression was correlated with tumor stage and progression. Gene Set Enrichment Analysis (GSEA) showed that PRR11 was enriched in the cell cycle regulatory pathways. Immune infiltration analysis revealed that the number of T helper 2 (Th2) cells increased when PRR11 was overexpressed. These results confirm the role of PRR11 as a prognostic marker of lung adenocarcinoma by controlling the cell cycle and influencing the immune system to facilitate lung cancer progression.

Objective: To understand the antimicrobial resistance and genome characteristics of Campylobacter isolates recovered from retailed poultry meat samples in 20 provinces in China in 2020. Methods: In 2020, 265 Campylobacter strains including 244 Campylobacter jejuni and 21 Campylobacter coli collected from retailed poultry meat samples in China were tested for antimicrobial resistance to 9 antimicrobial compounds by using the agar dilution method. Forty-two selected isolates were sent for whole genome sequencing and 38 high-quality genomes were analyzed for their antimicrobial resistance genes, virulence genes, sequence types and genetic diversity. Results: The resistance rates of Campylobacter isolates from poultry meats to tetracycline, nalidixic acid and ciprofloxacin were the highest (84%-100%), with 53.2% of the isolates showing multidrug resistance in this study. The resistance rates of C. coli to erythromycin, azithromycin, telithromycin, gentamicin and clindamycin were significantly higher than those of C. jejuni (P<0.05). The resistance genes conferring resistance to β-lactams (100%, 38/38), quinolones (94.7%, 36/38), tetracycline (81.6%, 31/38) and aminoglycosides (50%, 19/38) were the most frequently detected among 38 Campylobacter genomes. C. jejuni carried more virulence genes than C. coli. In total, 19 and 17 sequence types (ST) were obtained from 20 sequenced C. jejuni and 18 C. coli isolates, respectively, including 5 novel STs. The isolates showed a high genetic diversity based on their sequence types. Conclusion: The phenomenon of antimicrobial resistance in Campylobacter from poultry meat sources in China is relatively serious, and resistance and virulence genes are widely distributed in Campylobacter. There is genetic diversity in Campylobacter.

Objective    To investigate the expression and biological function of centromere protein F (CENPF) in non-small cell lung cancer (NSCLC) and the association with prognosis. Methods    Through retrieving and analyzing the bioinformatics data such as Oncomine database, Human Protein Atlas (HPA), Kaplan-Meier Plotter, STRING and DAVID database, the expression of CENPF in both normal tissues and cancer tissues of lung cancer patients was identified, and the protein interaction network analysis, functional annotation and pathway analysis of CENPF with its associated genes were carried out. Results    CENPF was overexpressed in lung adenocarcinoma tissues, but not in normal tissues. The median overall survival (OS) of NSCLC patients with low expression of CENPF was significantly longer than that of patients with high expression of CENPF. Further sub-analysis showed that low expression group from lung adenocarcinoma patients had longer median disease-free survival and OS compared with high expression group patients. CENPF and its associated hub genes mainly affected the protein K11-linked ubiquitination in biological process, anaphase-promoting complex (APC) in cell composition, ATP binding in molecular function, and cell cycle in KEGG pathway. Conclusion    CENPF is regulated in tumorigenesis and progression of NSCLC, and its protein expression level has the value of early diagnosis and prognosis evaluation in lung adenocarcinoma. It is suggested that CENPF gene can be a potential target for molecular targeted therapy of NSCLC.

Objective:To discuss the clinical efficacy of modified Bushen Huoxuetang combined with autologous bone grafting and locking compression plate （LCP） in treating nonunion of long bone fractures， and the effect on microcirculation， osteogenic differentiation factor and bone metabolism index. Method:A total of 70 patients were randomly divided into control group and observation group by random number table， with 35 cases in each group. Patients in both groups received LCP. Patients in control group got Dieda Shenggu granule， 10 g/time， 1 time/day. Patients in observation group got Bushen Huoxuetang， 1 dose/day. The course of treatment lasted for 3 months， and 3-month follow-up data were recorded. On a weekly basis， the main symptoms， such as pain， tenderness， longitudinal percussion pain and swelling were checked， and the time of disappearing of main symptoms and signs were compared. On a weekly basis， a X-ray examination was performed for callus formation and fracture line， and the fracture healing time was recorded. Before and after treatment， Fugl-Meyer （FMA） was scored， and levels of fibrinogen （FIB）， whole blood viscosity （BV） （high shear， low shear）， plasma viscosity （PV）， platelet aggregation rate （PAR）， D-Dimer （D-D）， bone morphogenetic protein-2 （BMP-2）， BMP-7， insulin-like growth factor-1 （IGF-1）， vascular endothelial growth factor （VEGF）， transforming growth factor-β₁ （TGF-β₁）， osteocalcin （BGP）， osteoprotegerin （OPG）， procollagen type Ⅰ N-terminal propeptideserum amino pro peptide （PINP）， serum type 1 collagen cross-linked C-terminal peptide （S-CTX） and serum tartrate resistant acid phosphatase （TRACP） of type I procollagen were detected， and the safety was evaluated. Result:Disappearance time of symptoms and signs and fracture healing time in observation group were all lower than those in control group （P<0.01）. At the third month after treatment， and during the three-month follow-up， scores of callus and FMA （upper and lower limbs） in observation group were all higher than those in control group （P<0.01）. Levels of D-D， FIB， PAR， BV and PV （high-cut and low-cut）， BMP-2， BMP-7， IGF-1， VEGF， TGF-β₁， S-CTX and TRACP were all lower than those in control group （P<0.01）， whereas levels of BGP， OPG and PINP were higher than those in control group （P<0.01）. The curative effect of fracture healing was better than that of control group （Z=1.977， P<0.05）. And the limb function recovery was superior to that in control group （Z=1.970， P<0.05）. Conclusion:Based on autogenous bone and LCP， modified Bushen Huoxuetang can promote the fracture healing， shorten the course of disease， and promote the recovery of limb function， with a good clinical efficacy. It can improve microcirculation， promote the expression of osteogenic differentiation factor， regulate bone metabolism， and play a role in promoting fracture healing， with a safety in clinical use.
