ObjectiveTo compare the differences between wild Alpiniae Oxyphyllae Fructus(WAOF) and cultivated Alpiniae Oxyphyllae Fructus(CAOF) through a traditional quality evaluation system for medicinal materials. MethodsA total of 10 batches of WAOF and 12 batches of CAOF samples were collected from various regions of Hainan province. Relevant analytical methods from the 2020 edition of the Pharmacopoeia of the People's Republic of China were employed to observe the characteristics of WAOF and CAOF, followed by microscopic identification, thin-layer chromatography(TLC) identification, moisture content(toluene method), total ash, acid-insoluble ash, water-soluble and alcohol-soluble extracts(hot dipping method), water-soluble protein, total polysaccharides and total flavonoids(ultraviolet spectrophotometry), and volatile oil content(method A under general rule 2204). The contents of five active components(protocatechuic acid, chrysin, kaempferol, tectochrysin and nootkatone) were quantified using ultra-performance liquid chromatography(UPLC), and the antioxidant activity was evaluated. Building upon traditional quality evaluation of AOF, quantitative measurements were conducted on its appearance traits including diameter, length, plumpness(diameter/length ratio), and color. Canonical correlation analysis was performed using SPSS 26.0 to explore relationships between appearance traits and intrinsic quality. ResultsNo significant differences were observed between WAOF and CAOF in microscopic observation, TLC identification, moisture content, protocatechuic acid content, kaempferol content, odor, or antioxidant activity measured by 2,2ʹ-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS) method. WAOF exhibited significantly higher levels in water-soluble extracts, alcohol-soluble extracts, total polysaccharide content, water-soluble protein content, 100-grain weight, length, and total color difference(ΔE*ab) compared to CAOF(P<0.01). In contrast, CAOF showed significantly higher levels of total ash, acid-insoluble ash, content of total flavonoids, volatile oil content, chrysin content, tectochrysin content, nootkatone content, diameter, plumpness, lightness(L*), red-green chromaticity(a*), yellow-blue chromaticity(b*), and antioxidant activity measured by 1,1-diphenyl-2-picrylhydrazyl(DPPH) method compared to WAOF(P<0.01). Correlation analysis between 7 phenotypic traits and 8 quality traits revealed that among the phenotypic traits, plumpness, L*, a*, and b* exerted significant influence on intrinsic quality. Among the quality traits, total flavonoids, volatile oils, nootkatone, chrysin, and tectochrysin contributed substantially to intrinsic quality. ConclusionPlumpness, L*, a*, and b* of AOF significantly influence its intrinsic quality, and higher values of these parameters indicate relatively superior intrinsic quality. The comprehensive quality evaluation reveals that CAOF samples collected in this study are superior to their wild counterparts.

Objective To investigate dynamic changes in myocardial protein phosphorylation during the acute phase of myocardial infarction (MI) in mice. Methods Six 8-week-old C57BL/6J mice were randomly assigned to MI model (n=3) or sham-operated control (n=3) groups. Cardiac tissues were harvested 72 hours post-intervention for proteomic analysis. Phosphorylation modifications were systematically characterized using liquid chromatography-mass spectrometry (LC-MS). Bioinformatics analyses included differential phosphorylation screening, functional enrichment, hierarchical clustering, and protein-protein interaction network. Results LC-MS identified 1 921 differentially phosphorylated sites (20 tyrosine and 1 901 serine/threonine sites) across 851 proteins. Compared with controls, MI hearts exhibited significant phosphorylation upregulation at 1 545 sites and downregulation at 376 sites (P<0.05). Conclusions This study delineates MI-associated phosphorylation dynamics, providing mechanistic insights and potential therapeutic targets for acute MI intervention.

ObjectiveThe proteome of biological evidence contains rich genetic information, namely single amino acid polymorphisms (SAPs) in protein sequences. However, due to the lack of efficient and convenient analysis tools, the application of SAP in public security still faces many challenges. This paper aims to meet the application requirements of SAP analysis for forensic biological evidence’s proteome data. MethodsThe software is divided into three modules. First, based on a built-in database of common non-synonymous single nucleotide polymorphisms (nsSNPs) and SAPs in East Asian populations, the software integrates and annotates newly identified exonic nsSNPs as SAPs, thereby constructing a customized SAP protein sequence database. It then utilizes a pre-installed search engine—either pFind or MaxQuant—to perform analysis and output SAP typing results, identifying both reference and variant types, along with their corresponding imputed nsSNPs. Finally, SAPTyper compares the proteome-based typing results with the individual’s exome-derived nsSNP profile and outputs the comparison report. ResultsSAPTyper accepts proteomic DDA mass spectrometry raw data (DDA acquisition mode) and exome sequencing results of nsSNPs as input and outputs the report of SAPs result. The pFind and Maxquant search engines were used to test the proteome data of 2 hair shafts of2 individuals, and both obtained SAP results. It was found that the results of the Maxquant search engine were slightly less than those of pFind. This result shows that SAPTyper can achieve SAP fingding function. Moreover, the pFind search engine was used to test the proteome data of 3 hair shafts from 1 European person and 1 African person in the literature. Among the sites fully matched by the literature method, sites detected by SAPTyper are also included; for semi-matching sites, that is, nsSNPs are heterozygous, both literature method and SAPTyper method had the risk of missing detection for one type of the allele. Comparing the analysis results of SAPTyper with the SAP test results reported in the literature, it was found that some imputed nsSNP sites identified by the literature method but not detected by SAPTyper had a MAF of less than 0.1% in East Asian populations, and therefore they were not included in the common nsSNP database of East Asian populations constructed by this software. Since the database construction of this software is based on the genetic variation information of East Asian populations, it is currently unable to effectively identify representative unique common variation sites in European or African populations, but it can still identify SAP sites shared by these populations and East Asian populations. ConclusionAn automated SAP analysis algorithm was developed for East Asian populations, and the software named SAPTyper was developed. This software provides a convenient and efficient analysis tool for the research and application of forensic proteomic SAP and has important application prospects in individual identification and phenotypic inference based on SAP.

Objective To compare the effects of dexmedetomidine and midazolam on intraoperative blood pressure and postoperative 90-day outcome of endovascular treatment(EVT)in patients with acute anterior circulation large vessel occlusive stroke.Methods Retrospective consecutive patients with acute anterior circulation large vessel occlusion stroke who received EVT within 24 hours of onset,admitted to the Department of Neurology at the Second People's Hospital of Hefei from January 2024 to February 2025 were included.Patients were divided into the dexmedetomidine group and the midazolam group based on the choice of sedative in EVT.Baseline and clinical data were collected from patients,including sex,age,medical history(hypertension,diabetes,atrial fibrillation,stroke history),smoking history,blood pressure at admission(systolic,diastolic,mean arterial pressure),National Institutes of Health stroke scale(NIHSS)score at admission,trial of Org 10172 in acute stroke treatment(TOAST)classification,and site of vascular occlusion(internal carotid artery,M1 segment of the middle cerebral artery).Procedure related parameters,including intravenous thrombolysis before EVT,intraoperative use of tirofiban,modified thrombolysis in cerebral infarction(mTICI)grade,thrombectomy techniques(stent-retriever thrombectomy,aspiration thrombectomy,combined stent-retriever and aspiration thrombectomy,and other salvage measures),number of thrombectomy,time from onset to revascularization,time from puncture to revascularization,blood pressure during EVT(minimum systolic,minimum diastolic,and minimum mean arterial pressure),and blood pressure at the end of EVT(systolic,diastolic,and mean arterial pressure).The primary outcome was good prognosis at 90 days after EVT(modified Rankin scale score of 0-2 at 90 days),while secondary outcome was>20%decrease in mean arterial pressure during EVT,early neurological improvement(ENI;a decrease on NIHSS score no less than 8 or a reduction of NIHSS score to 0-1 at 24 hours after EVT),and early neurological deterioration(END;an increase of more than 2 points on the NIHSS at 24 hours after procedure).Safety outcomes included any intracranial hemorrhage within 48 hours after EVT,symptomatic intracranial hemorrhage within 48 hours after EVT(sICH;intracranial hemorrhage confirmed by head CT leading to neurological deterioration,with an increase in NIHSS score of at least 4 points,or the presence of potentially fatal intracranial hemorrhage on head CT),pneumonia within 2 weeks after EVT,and the 90-day mortality after EVT.The baseline and clinical data,EVT conditions,primary outcome,secondary outcome,and safety indicators were compared between the two groups.Univariate Logistic regression analysis was used to screen the variables associated with a decrease in mean arterial pressure>20%during EVT in patients with acute anterior circulation large vessel occlusive stroke.Variables with P<0.15 and those considered potentially influential based on clinical experience were included in multivariate Logistic regression analysis to identify predictors of a>20%decrease in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusive stroke.Results A total of 93 patients with acute anterior circulation large vessel occlusive stroke who underwent EVT were included,comprising 51 males and 42 females,aged 34 to 99 years,with an average of(71±13)years old.Among them,63 patients were in the dexmedetomidine group,and 30 patients were in the midazolam group.33 patients showed>20%decreases in mean arterial pressure during EVT,while 60 patients had ≤20%decreases.(1)Compare with the midazolam group,the proportion of female patients in the dexmedetomidine group was lower(36.5%[23/63]vs.63.3%[19/30],P=0.015),and the age was younger([69±13]years vs.[77±13]years,P=0.005).There were no statistically significant differences in other baseline and clinical data(all P>0.05).(2)In comparison with the midazolam group,the dexmedetomidine group had a higher proportion of patients with more thrombectomy procedures(1.00[1.00,2.00]times vs.1.00[1.00,1.25]times,P=0.011),END(27.0%[17/63]vs.6.7%[2/30],P=0.023),sICH within 48 hours(19.0%[12/63]vs.3.3%[1/30],P=0.041),and a decrease in mean arterial pressure>20%during EVT(42.9%[27/63]vs.20.0%[6/30],P=0.031).There were no statistically significant differences in the remaining EVT conditions,primary outcome,secondary outcome,and safety indicators(all P>0.05).(3)The results of univariate Logistic regression analysis showed that diastolic blood pressure at admission(P=0.002),mean arterial pressure at admission(P=0.009),and dexmedetomidine sedation(P=0.036)were the influencing factors of a decrease>20%in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusion stroke.(4)The results of multivariate Logistic regression analysis showed that dexmedetomidine sedation(OR,3.271,95%CI 1.057-10.126,P=0.040)and higher diastolic blood pressure on admission(OR,1.105,95%CI 1.006-1.213,P=0.037)were independent predictors of a decrease over 20%in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusive stroke.Conclusions Dexmedetomidine is an independent predictor of an over 20%decrease in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusive stroke,but there is no statistically significant differences in the rate of good neurological function at 90 days and 90-day mortality postoperatively between the two groups.Further prospective randomized controlled studies are needed.

Objective Compare the tip perfusion index(TPI)with the disappearance of eyelash reflex in guiding the timing of intubation for painless gastroscopy,in order to find the optimal timing for painless gastroscopy.Methods 362 patients who underwent painless gastroscopy from January to June 2024 were selected.According to the random number table method,they were divided into group N(122 cases,direct endoscopic examination after the disappearance of eyelash reflex),group NS(121 cases,endoscopic examination 30 seconds after the disappearance of eyelash reflex),and group E[119 cases,endoscopic examination after continuous increase of TPI(newly measured value>previous measured value more than 3 times)].The changes in heart rate(HR),mean arterial pressure(MAP),and percutaneous arterial oxygen saturation(SpO2)before anesthesia induction(T0),before intubation(T1),through the throat(T2),and after examination(T3)were recorded and compared among the three groups.The intubation waiting time(from the completion of general anesthesia induction to the moment of intubation)and the incidence of adverse reaction were compared among the three groups.Results The waiting time for endoscopy in group N was(5.52±2.17)s,which was significantly shorter than that in group E[(18.60±3.89)s]and group NS[(35.74±2.17)s],and the differences were statistically significant(P<0.01).At T1 time point,the SpO2 of the group E was significantly higher than that of group N and group NS,the differences were statistically significant(P<0.01).There were no statistical difference of SpO2 at T0,T2 and T3 time points among the three groups(P>0.05).There were no statistical differences in HR and MAP at the T0,T1,T2 and T3 time points among the three groups(P>0.05);The MAP and HR of the three groups of patients at time point T0 were significantly higher than those at time points T1,T2 and T3,and the differences were statistically significant(P<0.05).The incidence of lower jaw support in group E was significantly lower than that in group NS and group N,the incidence of body movement and the rate of additional propofol administration were significantly lower than those in group N,the incidence of coughing was significantly lower than that in group NS,and the differences were statistically significant(P<0.05).Conclusion The TPI is a simple,non-invasive,objective,and real-time predictor of the timing of intubation for painless gastroscopy,which is significantly better than guiding the timing of intubation through the eyelash reflex.When the TPI continuously increases from a low point,it is a good time for painless gastroscopy intubation.
