Objective:To investigate the relationship between the neutrophil- to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), C-reactive protein (CRP), and the efficacy of immunotherapy in patients with advanced non-small cell lung cancer (NSCLC).Methods:The clinical data of 47 patients with NSCLC who received immunotherapy at The First Affiliated Hospital of Anhui University of Science and Technology from December 2021 to May 2023 were retrospectively analyzed. Based on the duration of immunotherapy, patients with a duration of more than 1 year were classified as having a good immune response, while those with a duration of less than 1 year were classified as having a poor immune response. The clinical pathological characteristics of patients with good and poor immune responses were compared. The cutoff values for NLR, LMR, and CRP were calculated using receiver operating characteristic curves, and patients were grouped based on these cutoff values. The predictive probabilities of different combinations were compared. Univariate and multivariate Cox analyses were performed to identify factors affecting patient survival.Results:Significant differences were observed in the distribution of therapy lines (1 st-line vs. 2 nd-line treatment), NLR, LMR, and CRP levels between patients with good immune response and those with poor immune responses (all P < 0.05). The area under the curve (AUC) for NLR was 0.763 [95% CI: (0.608, 0.918)], the AUC for LMR was 0.715 [95% CI: (0.544, 0.875)], and the AUC for CRP was 0.697 [95% CI: (0.540, 0.853)]. To assess the diagnostic value of combined indicators in predicting the efficacy of immunotherapy in NSCLC, different indicators were combined, resulting in the variables NLR + LMR, NLR + CRP, LMR + CRP, and NLR + LMR + CRP. Receiver Operating Characteristic curves were plotted based on the probabilities. The combination of NLR + LMR + CRP showed the best predictive performance, with an AUC of 0.897 [95% CI: (0.806, 0.988)]. Univariate and multivariate Cox analyses indicated that LMR [ HR: 0.428; 95% CI: (0.213, 0.858), P = 0.017] and the distribution of treatment lines [ HR: 1.815; 95% CI: (1.005, 3.642), P = 0.033] were important independent prognostic factors for progression-free survival. Conclusions:NLR, LMR, and CRP are correlated with immunotherapy efficacy in patients with NSCLC and provide predictive value. LMR and treatment line are independent prognostic factors for progression-free survival.

[Objective]To analyze the digital research literature in the field of traditional Chinese medicine culture,to understand the hot topics and lineage of research on digitization of traditional Chinese medicine culture and analyze the future development trend.[Methods]China National Knowledge Infrastructure(CNKI)and Web of Science(WOS)databases were searched to collect relevant journal literature in the field of digitization of traditional Chinese medicine culture from January 2006 to February 2024.CiteSpace 6.1.R6 software was used to analyze the evidence visualization of the included literature,including the trend of publication,the cooperation of authors and institutions,journal distributions,keyword co-occurrence,clustering and burst word analysis,and the visualization map was drawn.[Results]A total of 523 documents were included in the analysis.The number of studies on digitization of traditional Chinese medicine culture was generally on the rise;there were 82 core authors,with a total of 184 articles(35.18%),and the core group of authors had not yet been formed.Research institutions were mainly located in Beijing and Shanghai,and there was less exchange and cooperation among different institutions and scholars.High-frequency keywords in the field of digitization of traditional Chinese medicine culture included Chinese medicine,communication,new media and international communication,etc.,of which cultural self-confidence,integrated media and popularization of science were hot and cutting-edge topics in recent years.[Conclusion]In the past years,the digital research on Chinese medicine culture had shown more obvious features of digital integration,more focused direction of digital empowerment,and a focus on digital inheritance and dissemination direction research.In the future,researchers should further improve the construction of the research system,promote the cooperation of scholars in different fields,adopt interdisciplinary research methods and promote the diversification of research contexts.

This study was aimed at exploring the epidemic characteristics and spatio-temporal evolution patterns of severe fever with thrombocytopenia syndrome(SFTS)in Henan Province from 2011 to 2022,to provide a reference for prevention and control ef-forts.Data on SFTS in Henan Province from 2011 to 2022 were collected from the Information Management System for Infectious Dis-ease Reporting,and epidemiological characteristics and spatio-temporal evolution patterns were investigated through spatial autocorre-lation analysis,standard deviation ellipse analysis,and spatial-centered transfer curves,on a district-county basis.From 2011 to 2022,a total of 5 471 SFTS cases associated with 81 deaths were reported in Henan Province.The incidence rate showed an increasing trend(χ2trend=23.24,P<0.001),and the average annual incidence was 0.4 677/100 000.The case-fatality rate showed a decreasing trend from 2011 to 2019(χ2trend=8.86,P=0.003),but an increasing trend from 2020 to 2022(χ2trend=12.93,P<0.001).The average an-nual case-fatality rate was 1.48%.The peak incidence period was from May to July;this period accounted for 58.75%of the total cases.Females(59.39%),individuals 60-80 years old(55.40%),and farmers(96.64%)were the high prevalence groups.The disease was distributed primarily in Xinyang City,and Shangcheng County had the highest incidence rate(27.411 8/100 000).Spatial aggregation was observed in the southeastern region(Moran's I>0,P<0.001),and the disease centers were all located in Guangshan County,Xin-yang City,and showed southeast-northwest-southeast-northwest-southeast-northeast-southwest movement during the 12-year pe-riod.In conclusion,from 2011 to 2022,SFTS in Henan Province had a high incidence in May to July,and females,older people,and farmers were the high-risk groups.Spatial aggregation was observed in the southeastern region,along with spread to surrounding areas.Xinyang City is therefore a key area for the prevention and control of SFTS.

Objective To analyze and compare the efficacy of DNA barcode,i.e.,Cytochrome b(Cytb)and 12S ribosomal RNA(12S rRNA)gene sequences,in the species identification of wildlife.Methods DNA extraction,quantification,PCR amplification of Cytb and 12S rRNA gene fragments,Sanger sequencing,and sequence alignment analysis were performed on ten wildlife samples.Results Both gene fragments were successfully amplified in six samples,while Cytb alone was successfully amplified in 1 sample,and 12S rRNA alone in 3 samples.Sequence analysis indicated that Cytb enabled species-level identification for 6 samples(Gallinula chloropus,Streptopelia orientalis,Phasianus colchicus,Falco naumanni,Myiopsitta monachus and Lynx lynx)and genus-level identification for 1 sample(Lepus).In contrast,12S rRNA achieved species-level identificaggion for 8 samples(Gallinula chloropus,Lepus sinensis,Phasianus colchicus,Myiopsitta monachus,Muntiacus reevesi,Macaca mulatta and Lynx lynx),representing seven species,and genus-level identification for 1 sample(Falco).However,by combining Cytb and 12S rRNA,all samples could be identified to the species level.Conclusion When applying DNA barcodes to wildlife identification,the Cytb and 12S rRNA gene regions analyzed here can effectively identify common species such as Gallinula chloropus and Streptopelia orientalis,but face difficulties in distinguishing closely related species within the same genus.Therefore,when conducting wildlife species identification,it is recommended to use two or more DNA barcode markers.

With the deepening of the modernization of traditional Chinese medicine(TCM),the analysis of mineralogical features of mineralogical TCM,as an important part of TCM,has received more and more attention.At present,the research of mineral-based traditional Chinese medicine is faced with problems such as confusion of medicinal resources,unclear material basis,and low exclusivity of quality standards,while common analytical techniques have certain limitations in quantitative analysis,sensitivity and comprehensive characterization,which restrict the modernization research of mineral-based medicines and its clinical applications.The advanced mineral identification and characterization system integrates energy spectrum and spectral analysis techniques,combined with efficient data processing algorithms,which can rapidly and accurately analyze mineral components qualitatively and quantitatively,but its application in mineral medicine research is still in its infancy.This article reviews the common analytical techniques for mineral medicine and the potential application of advanced mineral identification and characterization system in the identification of mineral Chinese medicine matrix and quality control.The advanced mineral identification and characterization system can not only accurately distinguish the mineralogical characteristics of mineral medicines,such as the mineral composition,elemental state and embedded characteristics,and provide data support for the research of mineral medicine resources,but also provide scientific basis for the establishment of systematic quality standards,the analysis of the preparation mechanism,the revelation of its potential medicinal effect of the material basis and the control of the risk of heavy metals.

Objective:To analyze the correlation between bone metabolism indicators,ultrasound quantitative parameters,and prediction of osteoporosis fracture risk assessment tool(FRAX)in elderly patients with osteoporosis(OP).Methods:A total of eighty elderly patients with OP who admitted to Wuxi Affiliated Hospital of Nanjing University of Chinese Medicine from December 2023 to December 2024 were selected.Based on the results of measuring bone quality by dual energy X-ray absorptiometry(DXA),they were divided into bone loss group(26 cases),moderate group(41 cases),and severe group(13 cases).All patients underwent measurements for N-terminal osteocalcin(N-MID OCN),total type I collagen N-terminal extended peptide(TP1NP),25 hydroxyvitamin D(25-OH VitD),parathyroid hormone(PTH),and β-collagen specific sequence(CROSSL)bone metabolism indicators when they were enrolled in groups.They underwent examinations of ultrasonic quantitative parameters included ultrasonic bone density(T value),ultrasound conduction velocity(SOS)and bone quality index(BQI),as well as FRAX prediction.The results of bone metabolism indicators,the examination of ultrasound quantitative parameter,and FRAX prediction were compared among the three groups of elderly patients with OP.Using Pearson linear correlation analysis analyzed the relationship among the three factors.Results:The N-MID OCN and 25-OH VitD levels in the severe group were lower respectively than those in the moderate group and the bone loss group,while the TP1NP,PTH,and CROSSL levels were higher than those in the moderate group and the bone less group,and the differences among the three groups were statistically significant(F=31.646,75.055,110.274,93.321,59.246,P<0.05).The T value,SOS,and BQI in the severe group were lower than those in the moderate group and the bone loss group,and the differences among the three groups were statistically significant(F=81.980,108.985,76.327,P<0.05).The levels of proximal humeral fracture(PHF)and postmenopausal osteoporosis fracture(PMOF)in the severe group were higher than those in the moderate group and the bone loss group,and the differences among the three groups were statistically significant(F=57.086,118.079,P<0.05).Pearson linear correlation analysis showed that the N-MID OCN and 25-OH VitD levels were positively correlated with T value,SOS,and BQI in elderly patients with OP(r=0.398,0.617,0.769,0.752,0.500,0.654,P<0.05),and were negatively correlated with PHF and PMOF(r=-0.504,-0.534,-0.572,-0.662,P<0.05).The TP1NP,PTH,CROSSL levels were negatively correlated with T value,SOS and BQI(r=-0.745,-0.751,-0.634,-0.733,-0.728,-0.569,-0.709,-0.648,-0.611,P<0.05),and were positively correlated with PHF and PMOF(r=0.612,0.558,0.602,0.700,0.695,0.740,P<0.05).Conclusion:The bone metabolism indicators of elderly patients with OP are correlated significantly with ultrasound quantitative parameters and FRAX prediction,which can be used as an important scheme in clinical assessment for bone strength and fracture risk.

Objective:To investigate the prenatal echocardiographic features of fetuses diagnosed with Ebstein anomaly (EA), identify prognostic factors affect the fetal and neonatal mortality, and evaluate the clinical value of the Simpson Andrews Sharland prognostic score (SAS prognostic score).Methods:A retrospective cohort study was conducted on 37 fetuses diagnosed with EA via prenatal and postnatal echocardiography at Guangdong Provincial People′s Hospital from June 2012 to June 2024. The echocardiographic features of EA patients were summarized. According to the patients′ survival statuses during the fetal and neonatal periods, they were divided into survival group and death group for a comparative analysis of key echocardiographic parameters, as well as SAS prognostic score. Also, receiver operator characteristic (ROC) curve was employed to assess the predictive abilities of various indicators. Finally, based on the medium-and long-term prognostic outcomes of EA cases, the predictive value of the SAS system was evaluated. The t test, Mann-Whitney U test, and Fisher exact test were used for group comparison. Results:Regarding the 37 EA cases, the gestational age at the initial diagnosis was (29±4) weeks. All of EA fetuses exhibited echocardiographic characterized by tricuspid regurgitation (TR) originating below the native tricuspid annulus with the severity varied, accompanied by manifestations such as right atrial enlargement. Of all cases, 5 cases (14%) died prenatally, and 32 cases (86%) were born alive. Postnatally, 4 cases died preoperatively, 1 case died postoperatively, and 27 cases survived. Compared with the survival group, the death group had a significantly higher average SAS prognostic score (6.9±1.1 vs. 2.0±1.5, t=9.17, P<0.001), right atrium (RA) to left atrium (LA) transverse diameter ratio (2.0±0.5 vs. 1.3±0.2, t=4.87, P=0.001) and TR area to RA area ratio (0.8±0.2 vs. 0.4±0.2, t=5.27, P<0.001). According to the ROC analysis, the optimal predictive value indicators are RA to LA transverse diameter ratio (AUC=0.93, 95% CI 0.81-1.00) and the TR area-to-RA area ratio (AUC=0.93, 95% CI 0.85-1.00); the optimal cut-point values were 1.5 and 0.5, respectively. Of 32 born alive cases, 21 cases (66%) didn′t undergo surgery, 2 cases (6%) underwent bidirectional Glenn surgery, and one case (3%) underwent tricuspid valvuloplasty. All 17 cases with SAS score≤2 survived, while all 9 cases with SAS score≥6 died. Among the 11 cases with a score from 3 to 5, 8 cases achieved a biventricular outcome. Conclusions:The typical echocardiographic feature of EA fetuses is that the originating point of TR is below the native tricuspid annulus and the severity can vary. The SAS score is essential for tiered prognosis. When the SAS is 3-5, dynamic monitoring for TR and RA enlargement should be employed to help guide prenatal intervention and reduce fetal and neonatal mortality.
