With the rapid development of information technology， research on ancient TCM books has shifted from the traditional collation and digitization into intelligent knowledge service， thereby achieving the deep integration of ancient TCM books collation and clinical needs. Based on the clinical problem and knowledge element theory， we implemented in-depth indexing and knowledge mining for 600 kinds of ancient TCM books， built a knowledge sharing service platform for ancient TCM books by integrating database， cloud platform， knowledge graph and other technologies， and carried out the thematic literature research and developed databases for four major diseases including stroke， heart failure， liver cirrhosis， and diabetes. The digital intelligence products have been applied in hundreds of hospitals for evaluation and feedback. Finally， through "digital processing plus intelligent application"， the two-way interaction between ancient TCM books and current clinical practice is realized， and the path and paradigm of ancient TCM books knowledge serving the modern prevention and control of major diseases is formed， providing reference for the innovative utilization of ancient TCM books.

Objective To retrospectively analyze the distribution and drug resistant characteristics of isolated pathogens （especially Gram-negative bacteria） in hospital and promote the rational use of antibacterial drugs. Methods The pathogens and drug sensitivity test results were collected from the whole hospital every quarter from July 2018 to March 2023, and were conducted retrospective analysis. Results A total of 14 844 pathogens were isolated and detected, including 4 757 Gram-positive bacteria （32.05%） and 10 087 Gram-negative bacteria （67.95%）. The detection rate of extended spectrum beta-lactamases Escherichia coli was 43.23%, and it maintained high sensitivity to carbapenems and enzyme inhibitors, and the sensitivity rate was about 99.00%. The drug resistance of Klebsiella pneumoniae was more serious, and carbapenem-resistant, multi-drug resistance and extensively-drug resistance appeared. In 2022，the detection rate of carbapenem-resistant Klebsiella pneumoniae was 54.82%; the detection rates of carbapenem-resistant Pseudomonas Aeruginosa and carbapenem-resistant Acinetobacter baumannii in non-fermentative bacteria were 22.02% and 74.34%, the detection rate of multi-drug resistant Acinetobacter baumannii was >70%. Conclusion The problem of drug resistance of Gram-negative bacteria was still serious, especially in Klebsiella pneumoniae and Acinetobacter baumannii. The problem of bacterial resistance poses great challenges to clinical treatment, and it is necessary to conduct regular monitoring and promote rational drug use.

ObjectiveTo understand the mortality trends among residents of Fuling District， Chongqing， before and after theCOVID-19 outbreak， and to provide references for the government to formulate disease prevention and control policies and measures. MethodsData on mortality and population in Fuling District from 2017 to 2022 were collected to analyze population mortality and standardized mortality rates， and to compare the changes in the causes of death by year and before and after the pandemic. ResultsFrom 2017 to 2022， the crude mortality rate in Fuling District showed an upward trend （APC=3.04%， P<0.05）， while the standardized mortality rate showed a downward trend （APC=-6.47%， P<0.01）. The mortality rate of males was higher than that of females （P<0.05）， with different age groups having different causes of death composition. The highest proportion of deaths in 0-year-old group was from infectious diseases， maternal and neonatal diseases， and nutritional deficiencies， the highest proportion of deaths in the 1‒24 age group， with the exception of those aged 5‒9， was from injuries， and the main cause of death for residents aged 25 and above was chronic diseases. The mortality rate of mental and behavioral disorders rose from the 13th to the 9th place. According to the epidemic situation of COVID-19， there were no changes in the top five causes of death among the entire population. The motility rate of endocrine， nutritional and metabolic diseases rose from the sixth to the fifth place in male population， and the motility rate of malignant tumor rose from the 3rd to the 2nd place in female population. ConclusionThere are no changes in the top five causes of death among the entire population of Fuling District before and after the COVID-19 outbreak. Chronic diseases remain the main cause of death. It is necessary to control the risk factors for cardiovascular and cerebrovascular diseases such as hypertension， diabetes， and dyslipidemia， and to curb the rising trend of mortality rates from strokes and acute myocardial infarction. For deaths caused by accidental injuries， targeted health education should be conducted for different populations.

Elemental imaging analysis based on laser induced-breakdown spectroscopy(LIBS)can provide significant reference value for oil and gas exploration activities.Improving the scanning speed and spatial resolution of LIBS elemental imaging analysis instruments contributes to enhancing the efficiency of mineral surface elemental analysis,which is crucial for achieving in-situ,real-time,and rapid LIBS analysis.In this study,a high-speed scanning LIBS elemental imaging analysis instrument was developed based on a scanning mirror device,achieving a scanning speed of 100 Hz and a spatial resolution of 50 μm.The stability of spectral data collected by this instrument was validated using aluminum alloy standard samples with uniform elemental distribution.The experimental results showed that the relative standard deviations(RSD)of the spectral data collected at different locations were 2.76％,2.79％,2.35％and 2.55％,respectively,demonstrating that the instrument's performance met analysis requirements.Analysis of spectral acquisition channels led to the selection of the 337-595 nm spectral range.Imaging analysis of major elements on the surface of meteorite mineral samples with complex matrices was conducted using this instrument,coupled with a multi-element imaging algorithm enabling visualization analysis of four major elements on the same image.The results revealed a higher level of detail and complexity in element distribution.The study demonstrated that this instrument,combined with multi-element imaging analysis algorithms,could provide crucial technical support for rapid imaging of element distribution in minerals at a microscopic scale during geological research.

Objective To understand the prevalence characteristics of influenza and changes of influenza virus strains,and provide reference for the prevention and control of influenza in the province.Methods Surveillance da-ta about influenza in Hunan Province from 2014 to 2023 were exported from China Influenza Surveillance Informa-tion System.Differences in the percentage of influenza-like illness(ILI)cases(percentage of influenza-like cases[ILI％]in outpatient and emergency department visits)among different years and different populations,as well as the positive rate of influenza virus in ILI specimens were compared.Results From 2014 to 2023,over 2.65 million cases of ILI were reported,with an ILI％of 4.70％.ILI％among different years presented statistically significant differences(P＜0.001).People aged 0-14 years old were the main population with ILI,accounting for 82.90％.The positive rate of influenza virus in ILI specimens was 14.14％,the positive rate of influenza virus among diffe-rent years and age groups were both significantly different(both P＜0.001).The main prevalent influenza strains from 2014 to 2023 included types A(H1N1),A(H3N2),B(Victoria),and B(Yamagata),alternating among di-fferent years.However,type B(Yamagata)strains were not detected from 2020 to 2023.There were basically two influenza prevalence seasons every year,namely winter-spring and summer.Conclusion People＜15 years old are the main population of influenza,and the prevalence peaks are in winter-spring and summer.From 2021 to 2023,the prevalence alternates mainly among 3 types:A(H1N1),A(H3N2),and B(Victoria).

Objective This research was to evaluate the integrity of visual pathways in patients with Parkinson disease(PD)by visual evoked potential(VEP),especially those with visual hallucinations.Methods A total of 76 PD patients were enrolled in this study.According to the presence or absence of visual hallucinations,they were divided into two groups:24 patients with visual hallucinations and 52 patients without visual hallucinations.At the same time,22 sex-and age-matched healthy controls were selected.All subjects underwent VEP test,and Unified Parkinson's Disease Rating Scale(UPDRS),Hoehn&Yahr stage(H-Y stage)and Mini-mental State Examination(MMSE)were performed for PD patients.Results The latencies of N75,P100 and N135(88.26±10.47)ms,(118.48±8.53)ms,(144.71±9.48)ms were significantly longer in PD patients with visual hallucinations than in those without visual hallucinations[(79.00±6.96)ms,(108.60±7.01)ms,(135.95±8.21)ms](P<0.001).However,the amplitudes of N75-P100 and N135-P100[4.35(2.73,7.30)μV]、[6.40(4.15,9.90)μV]were significantly lower in PD patients with visual hallucinations than in those without visual hallucinations[7.10(5.28,9.98)μV]、[9.05(6.30,12.60)μV](P<0.001,P=0.037).Correlation analysis showed that P100 latency was positively correlated with H-Y stage,UPDRS-I,UPDRS-II,and UPDRS-III scores(r=0.537,P=0.007),(r=0.635,P=0.001),(r=0.594,P=0.004)and(r=0.558,P=0.005)in PD visual hallucinations group.Conclusion The integrity of the visual pathway is impaired in PD patients with visual hallucinations.As the progression of the disease,the impairment of visual pathway may be further deteriorated,which may extend beyond the upper pathways of visual pathway to the brain.

Objective To investigate the effect of parent-child alienation on depression in surface ship officers and soldiers based on the theory of"diathesis-stress",and the mediating role of resilience between parent-child alienation and depression in them.Methods A cross-sectional study was conducted on 599 officers and soldiers from a surface ship unit.The participants were surveyed with inventory of alienation toward parents,connor-davidson resilience scale and patient health questionnaire-9 to obtain and analyze their demographic-military characteristics of their depression scores.The participants with depression scores ≥5 were recruited as the subjects,and Spearman correlation analysis was used to explore the correlation among parent-child alienation,resilience and depression.On the basis of hierarchical regression analysis,AMOS software was used to establish a structural equation modelling of intermediary effects.Results The depression score was 1(0,4)in the participants,and the depression scores of those with service length ≥11 years were comparatively higher than those with shorter length.Our results indicated that parent-child alienation was positive correlated with depression(r=0.451,P＜0.001),while resilience was negatively correlated with depression and parent-child alienation(r=-0.412,-0.407,P＜0.001).Regression analysis revealed that parent-child alienation had a direct positive predictive value for depression(β=0.574,P＜0.001),and resilience showed a negative predictive value for depression(β=-0.211,P＜0.01).Model analysis displayed that resilience had a significant mediating role in the effect of parent-child alienation on depression among these surface ship officers and soldiers,with an effect value of 0.088,and accounting for 15.86％of the total effect.Conclusion Parent-child alienation has a significant influence on depression among surface ship officers and soldiers,with resilience playing a partial mediating role.

Objective:To analyze the levels of antibody to measles virus in cord blood of newborns in Ankang city, and provide reference for the development of measles prevention and control measures and strategies.Methods:From January to December, 2023, 1 058 pregnant women from 10 county-level general hospitals in Ankang city were recruited in this study. Neonatal umbilical cord blood samples were collected for detecting IgG antibody against measles with ELISA. SPSS 21.0 software was used to analyze the positive rate of antibody to measles virus and the influencing factors.Results:The overall positive rate of IgG antibody to measles virus was 89.22% (944/1 058), and the geometric mean concentration (GMC) was 570.26 mlU/ml. The positive rates of IgG antibody against measles virus in umbilical cord blood of neonates born to women aged ≤20, 21-25, 26-30, 31-35, and ≥36 years old were 91.07% (51/56), 90.27% (232/257), 89.54% (351/392), 88.12% (230/261), and 86.96% (80/92), respectively (χ 2=1.355, P=0.852). Multivariate logistic regression analysis showed that the positive rate of IgG antibody against measles virus in umbilical cord blood samples was higher in neonates with gestational age ≥37 weeks than in those with gestational age <37 weeks [OR (95%CI): 0.403 (0.262-0.622)]. Besides, the positive rate was also higher in newborns with a birth weight of 3.0-3.5 kg than in those with birth weight <3 kg or ≥3.5 kg [OR (95%CI): 0.868 (0.462-1.629), 1.765(1.087-2.865)]. Conclusions:The positive rate and the GMC of IgG antibody to measles virus in neonatal umbilical cord blood decrease with maternal age. It is recommended that women of childbearing age should receive supplementary immunization with measles-containing vaccine before pregnancy.

Objective: To explore the linear associations between social support, coping strategies, depression, anxiety, and cognitive function among people with type 2 diabetes mellitus (T2DM) using a path-analytic method. Methods: This cross-sectional study enrolled 496 individuals hospitalized due to T2DM. Well-trained investigators conducted face-to-face interviews with the participants using the Social Support Rating Scale, the Chinese version of Medical Coping Modes Questionnaire, the Hospital Anxiety and Depression scale, and the Mini Mental State Examination to measure social support (including objective support, subjective support, and support utilization), coping strategies (including confrontation, avoidance, and acceptance-resignation), depression/anxiety, and cognitive function, respectively. A path analysis was used to elucidate the linear associations between social support, coping strategies, depression, anxiety, and cognitive function. Results: In the final path model with satisfactory model fit, objective support was found to be associated with cognitive function not only directly but also indirectly through confrontation coping and depression, and acceptance-resignation coping and depression/anxiety. Further, subjective support was found to be associated with cognitive function indirectly through depression/anxiety, as well as serially through acceptance-resignation coping and depression/anxiety. Support utilization was found to be associated with cognitive function indirectly through confrontation coping and depression, as well as through acceptance-resignation coping and depression/anxiety. Conclusion Social support, coping strategies, depression, and anxiety were associated with cognitive function among people with T2DM, and these associations were best explained by a serial mediation model from social support, coping strategies, and depression and anxiety to cognitive function.
