ObjectiveTo analyze the changes in the degree of coordination of China's major epidemic prevention and control efforts before and after the outbreak of the Corona Virus Disease 2019 (COVID-19), so as to explore the impact of epidemic prevention and control measures on coordination dynamics. MethodsA total of 3 864 policy documents related to epidemic prevention and control from January 2000 to December 2020 across 31 provinces (autonomous regions, and municipalities) in China were systematically collected. Contents specific to collaborative and cooperative efforts were extracted, and the extent of interdepartmental coordination were quantified to assess the effectiveness of epidemic prevention and control efforts. Wilcoxon signed-rank test was adopted to statistically analyze the differences between the indicators before and after the epidemic. ResultsThe average overall coordination level for major epidemic prevention and control in 31 provinces (autonomous regions, and municipalities) increased from 43.06% to 97.62%, and the average coordination levels in the eastern, central, and western China soared from 42.29%, 37.50%, and 47.46%, to 98.81%, 96.20%, and 97.46%, respectively, with statistically significant differences (all P<0.05). In terms of department categorization, coordination levels in the professional departments and the key support departments peaked at 100.00%, while other support departments rose to 95.43%, with an increase of 77.15%, 181.85%, and 139.89%, respectively, exhibiting noteworthy statistically significant differences (all P<0.001). ConclusionThe scope of coordination departments of China’s major epidemic prevention and control exists a remarkable surge following the COVID-19 outbreak, notable heightened coordination is particularly observed among the key support departments. Future endeavors should prioritize the roles played by diverse departments in epidemic prevention and control, enhancing both the clarity of departmental responsibilities and the effectiveness of interdepartmental coordination.

Aim To observe the effects of Wenfei Jiangzhuo formula(WFJZF)on rats with vascular de-mentia and investigate its possible mechanism of ac-tion.Methods Thirty-six healthy male SD rats were randomly divided into the sham group,model group,donepezil group,and low-dose,medium-dose and high-dose groups of Wenfei Jiangzhuo formula,with six rats per group.Except for the sham group,the other groups were prepared as VaD models,and each group was gavaged with the corresponding drugs after suc-cessful modeling,and tests were performed after three weeks of treatment.Behavioral,hippocampal CA1 area morphology,neural dendrites and mitochondrial chan-ges were observed in all groups of rats,and phospho-glycerate mutase 5(PGAM5),dynamics-related pro-teins1(Drp1),opticatrophyprotein-1(OPA1),and other proteins were detected in each group.Results Compared with the sham group,rats in the model group and each intervention group had prolonged es-cape latency(P＜0.05),a shorter number of travers-als across the platforms(P＜0.05),a sparse morphol-ogy of hippocampal neurons,a reduction in the number of secondary dendritic spines,and a rupture of the out-er membrane of the mitochondria;the expression of the PGAM5 and Drp1 proteins in hippocampal tissues was elevated(P＜0.05),and the expression of the OPA1 and Mfn1/2 protein expression decreased(P＜0.05);compared with the model group,donepezil group and Wenfei Jiangzhuo formula high-dose group of rats had shorter evasion latency(P＜0.05),increased number of times to traverse the platform(P＜0.05),increased number of hippocampal neurons,tightly packed,more secondary dendritic structures,and reduced mitochon-drial damage;the expression of PGAM5 and Drp1 pro-teins was reduced(P＜0.05),and the expression of OPA1 and Mfn1/2 proteins was elevated(P＜0.05).Conclusions Wenfei Jiangzhuo formula can regulate the PGAM5-Drp1 signaling axis to improve the balance of mitochondrial homeostasis,thus improving the cog-nitive condition of the brain and exerting cerebroprotec-tive effects.

Objective:Based on the data compilation and analysis of the disease burden of esophageal cancer attributed to alcohol consumption in China over the past three decades(1990-2019),this study aims to explore how to strengthen the formulation and management of public health policies to control the disease burden caused by this disease. Methods:Based on the data from the Global Burden of Disease(GBD)2019 study database,indicators such as mortality rate and disability-adjusted life years(DALYs)were used to assess the disease burden of esophageal cancer attributed to alcohol consumption in China.Joinpoint regression software and the age-period-cohort model were employed to analyze the trends in disease burden and mortality rates over time by age,period,and cohort.Bayesian age-period-cohort analysis was used to predict the mortality rates of esophageal cancer attributed to alcohol consumption in China from 2020 to 2030. Results:From 1990 to 2019,the number of deaths from esophageal cancer attributed to alcohol consumption increased from 33 800 cases to 61 900 cases,while the standardized mortality rate decreased from 3.95 per 100 000 to 3.04 per 100 000.DALYs increased from 934 000 person-years to 1 512 600 person-years,and the DALYs rate decreased from 101.36 per 100 000 to 71.39 per 100 000.In 2019,both the number of deaths and DALYs reached their peak in the age group of 65-69 years with 58 800 deaths and a standardized mortality rate of 6.21 per 100 000 for males,and 3 100 deaths and a standardized mortality rate of 0.31 per 100 000 for females.Both the mortality rates and the DALYs rates increased with age.The Joinpoint regression analysis showed that the average annual percentage change(AAPC)of mortality rates attributed to alcohol consumption-related esophageal cancer was-0.97%[95%confidence interval(CI):-1.2%--0.8%],with an AAPC of-2.32%(95%CI:-2.6%--2.1%)for females and-0.81%(95%CI:-1.0%-0.6%)for males.The age-period-cohort analysis of mortality rates attributed to alcohol consumption-related esophageal cancer showed a net drift of-1.301%(95%CI:-1.577%--1.025%,P＜0.05).It is predicted that the burden of esophageal cancer mortality attributed to alcohol consumption will steadily increase during the period of 2020-2030. Conclusion:Compared to the overall trend of esophageal cancer burden,the burden of esophageal cancer attributed to alcohol consumption is declining at a slower rate.The burden of the disease is higher in the male population than that in females,and higher in the middle-aged and elderly population compared to the younger population.It is expected that in the coming years,the burden of esophageal cancer mortality attributed to alcohol consumption in China will steadily increase,suggesting that while focusing on the intervention for males and the middle-aged and elderly population,relevant departments should also strengthen health education in the entire population,formulate public health policies,and raise awareness of early prevention and risk factors of esophageal cancer among residents.

Objective To establish a rapid detection method for invasive candidiasis based on droplet digital polymerase chain reaction(ddPCR).Methods We developed an assay system using a microtitre-based digital PCR platform and designed primer probes specific for four Candida species,namely Candida albicans,Candida smoothii,Candida near-smoothii,and Candida tropicalis.(1)The Limit of Blank(LOB)range and positive judg-ment value were determined by analyzing No Template Control(NTC)samples.(2)The Limit of Detection(LOD)range was determined by diluting positive samples with 10 replicate extractions at each concentration gradient.(3)The Linear Limit of Quantitation(LOQ)range was determined by repetitive testing of diluted samples.(4)The linear range limit was determined through gradient dilution of the positive samples.(5)The coefficient of variation(CV),calculated from the logarithmic values of the resultant concentrations,was assessed by extracting and test-ing positive samples in 12 repetitions at both high and low concentrations.(6)Method reliability was evaluated by calculating the CV from the logarithmic values of the resultant concentrations obtained from clinical samples with fungal culture results.Results The ddPCR assay detected Candida LOB at a range of 0～81 copies/mL,with a positive threshold set at≥3 positive microdroplets.The LOD and LOQ were determined to be 3×102 copies/mL.The linear range for detecting different concentration gradients was found to be between 3×102 and 3×107 copies/mL,with high correlation coefficients observed for Candida albicans(R2=0.999 5),Candida smoothii(R2=0.998 9),Candida near-smoothii(R2=0.999 4),and Candida tropicalis(R2=0.999).Additionally,the coefficient of variation for the resultant concentration logarithmic values was less than 5%,meeting precision requirements.Furthermore,preliminary validation using clinical specimens demonstrated consistent results compared to clinical culture findings.Conclusion ddPCR exhibits rapidity,high sensitivity,good repeatability,and high specificity in detecting inva-sive candidiasis in critically ill patients.This study highlights the potential value of droplet digital PCR as a diag-nostic tool for invasive candidiasis.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.
