The study investigated the intrinsic changes in material basis of Angelicae Sinensis Radix during wine processing by headspace-gas chromatography-ion mobility spectrometry(HS-GC-IMS), headspace-solid phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS), and ultra-high performance liquid chromatography-quadrupole-orbitrap mass spectrometry(UPLC-Q-Orbitrap-MS) combined with chemometrics. HS-GC-IMS fingerprints of Angelicae Sinensis Radix before and after wine processing were established to analyze the variation trends of volatile components and characterize volatile small-molecule substances before and after processing. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were employed for differentiation and difference analysis. A total of 89 volatile components in Angelicae Sinensis Radix were identified by HS-GC-IMS, including 14 unsaturated hydrocarbons, 16 aldehydes, 13 ketones, 9 alcohols, 16 esters, 6 organic acids, and 15 other compounds. HS-SPME-GC-MS detected 118 volatile components, comprising 42 unsaturated hydrocarbons, 11 aromatic compounds, 30 alcohols, 8 alkanes, 6 organic acids, 4 ketones, 7 aldehydes, 5 esters, and 5 other volatile compounds. UPLC-Q-Orbitrap-MS identified 76 non-volatile compounds. PCA revealed distinct clusters of raw and wine-processed Angelicae Sinensis Radix samples across the three detection methods. Both PCA and OPLS-DA effectively discriminated between the two groups, and 145 compounds(VIP>1) were identified as critical markers for evaluating processing quality, including 4-methyl-3-penten-2-one, ethyl 2-methylpentanoate, and 2,4-dimethyl-1,3-dioxolane detected by HS-GC-IMS, angelic acid, β-pinene, and germacrene B detected by HS-SPME-GC-MS, and L-tryptophan, licoricone, and angenomalin detected by UPLC-Q-Orbitrap-MS. In conclusion, the integration of the three detection methods with chemometrics elucidates the differences in the chemical material basis between raw and wine-processed Angelicae Sinensis Radix, providing a scientific foundation for understanding the processing mechanisms and clinical applications of wine-processed Angelicae Sinensis Radix.

Objective To explore the effect of enriched environmental stimulation on mouse brain cognitive reserve to enhance the sensitivity of brain age gap estimation (BrainAGE).Methods Twenty-one healthy adult C57BL / 6J male mice,15 months old,were divided into a group with a standard environment and two groups with enriched environments.All the groups underwent magnetic resonance microcopy.Scaled subprofile model was used to analyze the features reflecting the changes of brain cognitive reserve.Results There were significant differences between the mean BrainAGE of the two groups with enriched environments and that of the remained standard environment group,then it's proved that some assumption might be reasonable that brain cognitive reserve could be estimated based on BrainAGE.Optim ized BrainAGE model made explanations for 58.9％ differences during stimulus phase in enriched environment.Conclusion Improved BrainAGE model gains high sensitivity when used to measure the redundancy of brain cognitive reserve.

The current proxy indicators and quantitative strategy were summarized for cognitive reserve,the findings of cognitive reserve was discussed then in brain aging and Alzheimer's disease,and some future research directions were presented about cognitive reserve.The reserve of brain explains the disjunction between clinical symptoms and the degree of brain damage,whereby some people can tolerate more of age-related or Alzheimer's disease pathology than others and maintain brain function.The cognitive reserve hypothesis has been widely used in epidemiological and neuroimaging studies,but it lacks a unified quantitative indicator.The future research of cognitive reserve should be focused on the development of quantitative indicators that cover a variety of potential factors dynamically.

Objective To compare the clinical value of ultrasound and X-ray guided percutaneous nephrolithotomy ( PCNL) for treat-ment of kidney calculi. Methods We searched relevant clinical controlled articles in PubMed,EMBASE/Cochrane library and CNKI data-base. The outcome indicators included stone clearance rate, complication rate,puncture time,blood loss,and hospital days. All data were ana-lyzed by Revman 5. 0 software. Results There were 9 articles involved in 1693 patients. The results suggested that there was no significant difference in stone clearance rate between ultrasound group and X-ray group[OR=1. 11,95%CI(0. 83,1. 49),P=0. 47]. However,the complication [OR=0. 43,95%CI (0. 27,0. 69),P=0. 0004],time to puncture[WMD= -4. 54,95%CI( -0. 45,-8. 62),P=0. 03], blood loss[WMD= -22. 77,95%CI( -36. 57,-8. 97),P=0. 001],and hospital days[WMD= -0. 16,95%CI( -0. 28,-0. 03),P=0. 02] were better in ultrasound group than those in X-ray group. Conclusion Ultrasound and X-ray guided PCNL had an equal stone clear-ance rate,but it seemed that ultrasound was better than X-ray in time to puncture and hospital days after operation. However,the results of this meta-analysis should be treated carefully because of limitation of data and heterogeneity.

Inflammation plays a critical role in intestinal ischemia reperfusion injury (IRI). Epigallocatechin-3-gallate (EGCG) has been demonstrated to possess anti-inflammatory effect. This study examined the effect of EGCG on intestinal IRI and explored the possible mechanisms. Male Wistar rats were randomly divided into three groups: sham-operated group (Sham), IRI control group (IRI) and IRI-EGCG group (EGCG). Rats in IRI-EGCG group were administered dissolved EGCG in drinking water (0.4 mg/mL) for 14 days prior to IRI induction. A rat model of intestinal IRI was established by ligating the superior mesenteric artery (SMA) for 30 min, followed by reperfusion for 1 h. Intestinal histology, pro-inflammatory cytokines and mediators were examined and the effect of EGCG on PI3K/Akt signalling was assessed. EGCG significantly alleviated the pathological changes of the intestine and suppressed the IRI-induced up-regulation of TNF-α, IL-1 and IL-6 mRNA and protein expression in the serum and intestine. The mechanism might be that EGCG enhanced the activation of PI3K/Akt signalling pathway. In conclusion, the administration of EGCG can significantly mitigate the acute intestinal IRI in rats by enhancing the activation of PI3K/Akt signalling pathway to suppress inflammatory response and might be a promising alternative for the prevention or treatment of intestinal IRI in the clinical practice.
