Objective:To investigate the efficacy and safety of endovascular therapy (EVT) guided by noncontrast CT (NCCT) in patients with large vessel occlusive stroke within a late window (6-24 hours after onset).Methods:Consecutive patients with acute large vessel occlusive stroke within a late window admitted to the General Hospital of Wanbei Coal-electricity Group Co., Ltd from July 1, 2023 to September 30, 2024 were included retrospectively. All patients completed CT angiography or magnetic resonance angiography to confirm the presence of anterior circulation large vessel occlusion and rule out intracranial hemorrhage (ICH). The Alberta Stroke Program Early CT Score (ASPECTS) ≥4 as assessed by NCCT images was used as the EVT screening criteria. The main outcome measure was the functional outcome assessed by the modified Rankin Scale at 90 days after onset, 0-2 was defined as good outcome. The secondary outcome measures were symptomatic ICH (sICH) and death within 90 days. Multivariate logistic regression analysis was used to determine the independent influencing factors of functional outcome. Results:A total of 74 patients with large vessel occlusive stroke within the late window were enrolled, including 42 males (56.8%), aged 68.69±11.62 years (range, 47-89 years), with a baseline National Institutes of Health Stroke Scale score 11.20±5.12 and a median baseline ASPECTS 7 (interquartile range, 6-8). Ten (13.5%) and 7 patients (9.5%) respectively experienced any ICH and sICH, and 7 (9.5%) died within 90 days after onset. Twenty-seven patients (36.5%) received EVT, 47 (63.5%) only received conventional drug treatment; 20 (27.0%) had good outcome, and 54 (73.0%) had poor outcome. Univariate analysis showed that the good outcome rate in the EVT group at 90 days was significantly higher than that in the non-EVT group (40.7% vs. 19.1%; χ2=4.054, P=0.044), and there was no significant difference in the proportion of patients in sICH (11.1% vs. 8.5%; χ2=0.701, P=0.505) and who died within 90 days (7.4% vs. 10.6%; χ2=1.000, P=0.495) compared to the non-EVT group. The proportion of patients receiving EVT in the good outcome group was significantly higher than that in the poor outcome group (60.0% vs. 27.8%; χ2=6.539, P=0.011). Multivariate logistic regression analysis showed that EVT was an independent influencing factor of good outcome (odds ratio 0.440, 95% confidence interval 0.144-0.987; P=0.041). Conclusion:Compared with the conventional drug treatment alone, EVT guided by NCCT evaluation can achieve better outcome in patients with large vessel occlusion stroke within late window, and does not increase the risk of sICH and death within 90 days.

Objective:To conduct a multi-center cross-sectional study of elderly patients with cognitive impairment based on real-world data; To analyze the clinical characteristics and core medication law of the disease population.Methods:The medical records of elderly patients diagnosed with cognitive impairment from January 1, 2016 to December 31, 2024 were retrieved from Chinese Evidence-based TCM Database. Excel 2010 software was used to collect general information, TCM syndrome elements and syndrome types, use frequency of Chinese materia medica, property, taste, meridian tropism, efficacy classification and other information, using PivotTable to establish Chinese materia medica matrix. IBM SPSS Modeler 18.0 software was used to display the frequency of co-occurrence among high-frequency Chinese materia medica, and the association rules were analyzed based on the Apriori algorithm. R language 4.4.1 was used for clustering analysis on Chinese materia medica and the cluster pedigree and correlation heat map were drawn.Results:A total of 1 194 elderly patients with cognitive impairment were enrolled, with a mean age of (79.51±7.65) years, and the highest frequency of comorbidities was hypertension (891 cases, 74.62%); AD was the most frequent diagnosis of cognitive impairment (367 times, 30.74%). The proportion of mild cognitive impairment in the low value group of Systemic Immune Inflammation Index (SII) was relatively high, and the high value group of SII was mainly vascular dementia and AD. Wind-phlegm blocking syndrome (106 times, 13.73%) topped the list; phlegm was the most frequent element of pathogenicity (353 times, 45.73%), and meridians and collaterals (194 times, 25.13%). Totally 328 prescriptions were included, involving 308 kinds of Chinese materia medica. The total recorded frequency of Chinese materia medica was 5 665, with tonifying herbs constituting the most frequently used category, accounting for 1 633 times; the medicinal property of drugs for treating elderly patients with cognitive disorders was mostly warm (103 times, 33.44%), the taste was mostly bitter (141 times, 45.78%), and attributed to the liver meridian (145 times, 47.08%); among the two and three association rules, the drug pairs with the highest confidence were Gastrodiae Rhizoma→Uncariae Ramulus cum Uncis (97.22%) and Hyperici Perforati Herba→Acanthopanacis Senticosi Radix et Rhizoma seu Caulis+Alpiniae Oxyphyllae Fructus (97.06%); five medicinal combinations were obtained by high frequency drug clustering analysis.Conclusions:Elderly patients with cognitive impairment are mainly diagnosed with AD. There may be a potential correlation between SII level and the progression of cognitive impairment. The drugs are used to tonify the kidney and replenish essence, detoxify and unblock collaterals, replenish qi and activate blood circulation, and awaken the brain and open the orifices. Shengmai Decoction, Renshen Yangrong Decoction and other TCM classic prescriptions can be used in clinic.

With increasing aging， cognitive impairment in elderly coronary heart disease is a "disease group" with high morbidity and mortality in the senior population， which seriously affects the health and quality of life of the elderly. This paper takes the "cardio-cerebral circuit" as the basis of co-morbidity， and under the guidance of the cardio-cerebral homoeopathy， based on the temporal sequential characteristics of the evolution of the disease mechanism of cognitive impairment in elderly coronary heart disease， we construct a “disease-syndrome-phase” prevention and treatment strategy based on the time-sequential characteristics of the pathogenesis of the disease mechanism of "deficiency-blood stasis-toxicity"， from the perspective of pathogenicity of the disease mechanism in time-phase and the spatial multidimensionality of cardio-cerebral homoeopathy. The prevention and treatment strategy of the "disease-syndrome-phase" is constructed from the perspective of the temporal phase of the disease mechanism and the multidimensionality of the space of cardio-cerebral homoeopathy. In the earlier stage， "kidney deficiency and brain emptiness are the foundation"， in the attack stage， "turbid stasis and brain injury are the key"， and in the progression stage， "toxicity and brain damage are the changes". It is emphasized that replenishing the deficiency and benefiting the kidneys to restore the smooth flow of collaterals， eliminating blood stasis and removing turbidity to promote the enrichment of blood， and detoxifying and clearing the heart to tranquilize the spirit and benefit the brain， the spatiotemporal thinking of cognitive impairment of coronary heart disease in the elderly is initially constructed with the spatial dimension to identify the location of the disease， and the temporal dimension to determine the stage of the disease， which will provide a theoretical basis for the spatiotemporal diagnostic and treatments for the heart and brain co-morbidities of TCM.

ObjectiveTo genotype Oncomelania hupensis， based on microsatellites， in different snail-bearing environments in Jiaxing City， Zhejiang Province， for population genetics analysis in order to explore the reasons and influencing factors for the existence or proliferation of snails and to provide scientific basis for effective monitoring and control of snails. MethodsA total of 90 snail samples from three populations were collected in Yaobang Village （YB） and Sanxing Village （SX） in Pinghu City， and Yunhe Farm （YH） in Xiuzhou District， all were selected for snail checking in key snail habitats of Jiaxing City in 2022. DNA of the snails was genotyped and analyzed for population genetics using nine microsatellite loci. ResultsA total of 84 alleles were observed， and the mean number of alleles （Na） was 7.889， 5.667， and 3.778 for YB， SX， and YH respectively； the number of effective alleles （NeA） was 4.807， 3.329， and 2.294， respectively； and the coefficients of inbreeding （F_IS） were 0.400， 0.377， and 0.493， respectively. Under the Infinite Allele Model （IAM）， the SX and YH might have a recent bottleneck. The NEstimator and LDNe software calculated effective population sizes （Ne） were above 31.9. AMOVA analysis showed that the variation of snails in the three populations mainly existed among individuals， accounting for 41.4% of the total variation. The value of the index of genetic differentiation between populations （F_ST） was 0.286， indicating a high degree of genetic differentiation. The results of the principal component analysis and phylogenetic tree were consistent， and the three populations were divided into two lineages， YB and SX were one lineage， and YH belonged to another independent lineage. Population history and dynamics analysis showed that the gene flow of the three populations was insufficient， population divergence history indicated that YH might have diverged from SX first， and YB was produced by the contact fusion of SX and YH. ConclusionThe genetic diversity of snail populations in Jiaxing City is generally low， and the snail populations are unstable， with a great degree of genetic differentiation and insufficient gene flow among populations. This study can provide a basis for evaluating the effectiveness of the control of the snail as well as monitoring the trend of the spread of the snail.

Insulin resistance has been regarded as a hallmark of diabetes heart disease (DHD). Numerous studies have shown that insulin resistance can affect blood circulation and myocardium, which indirectly cause cardiac hypertrophy and ventricular remodeling, participating in the pathogenesis of DHD. Meanwhile, hyperinsulinemia, hyperglycemia, and hyperlipidemia associated with insulin resistance can directly impair the metabolism and function of the heart. Targeting insulin resistance is a potential therapeutic strategy for the prevention of DHD. Currently, the role of insulin resistance in the pathogenic development of DHD is still under active research, as the pathological roles involved are complex and not yet fully understood, and the related therapeutic approaches are not well developed. In this review, we describe insulin resistance and add recent advances in the major pathological and physiological changes and underlying mechanisms by which insulin resistance leads to myocardial remodeling and dysfunction in the diabetic heart, including exosomal dysfunction, ferroptosis, and epigenetic factors. In addition, we discuss potential therapeutic approaches to improve insulin resistance and accelerate the development of cardiovascular protection drugs.

Objective: To perform an epidemiological survey of the first case with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Pinghu City of Jiaxing City, Zhejiang Province on March 13, 2022, so as to provide insights into the management of coronavirus disease (COVID-19) epidemics. Methods: According to the requirements of the Protocol on Prevention and Control of COVID-19 (8th Edition), epidemiological investigations were performed among 39 cases with SARS-CoV-2 infections in Pinghu City from March 13 to 20, 2022. Cases' demographics, clinical symptoms, history of immunization and exposure were collected, and close contacts were identified. Pharyngeal swabs were sampled from infected cases for detection of SARS-CoV-2 nucleic acid and whole-genome sequencing, and the source of infection and transmission route were investigated. Results: The index case for this COVID-19 epidemic was an imported case from Shanghai Municipality, who infected 6 persons via aerosol transmission when playing in the badminton venue of Pinghu National Fitness Center on March 9; subsequently, one of these infected cases infected another 18 persons when playing in the badminton venue of Jiadian Village Resident's Fitness Center in Zhapu Township on March 12. Sixteen confirmed cases were reported, and all cases were mild; another 23 asymptomatic cases were diagnosed, with no death reported. This epidemic occurred from March 11 to 20, with 3 generations of spread and a median incubation period of 3 days. The SARS-CoV-2 infected cases had a median age of 33.5 (interquartile range, 12.0) years and included 36 cases with a history of COVID-19 vaccination. There were 16 cases with fever, cough, runny nose and sore throat, and 13 cases with imaging features of pneumonia. The effective reproductive number (Rt) of the COVID-19 epidemic was 7.73 at early stage, and was less than 1 since March 21. Whole-genome sequencing identified Omicron BA.2 variant among 33 cases, which had high homology with the index cases. Conclusion This epidemic was a cluster of COVID-19 caused by imported Omicron BA.2 variant infection from Shanghai Municipality, and the COVID-19 transmission was mainly caused by indoor aerosols.

【Objective】 To understand the effect of long-term high-frequency platelet donation on the health, safety and platelet quality of blood donors. 【Methods】 From August 2020 to July 2022, blood donors who donated platelets for single collection in the station were selected as two groups: those who donated for 20-29 times and those who donated for 30-44 times. Such 14 test indexes as red blood cell count (RBC), hemoglobin (Hb), hematocrit (Hct), mean corpuscular volume (MCV), platelet count (Plt), white blood cell count (WBC), large platelet ratio (P-LCR), lymphocyte (LYM) , neutrophil (NE), mean hemoglobin content (MCH), mean hemoglobin concentration (MCHC), platelet specific volume (PCT), mean platelet volume (MPV) and platelet distribution width (PDW) were grouped and statistically analyzed for 5 times in each group. In addition, blood donors who have donated platelets more than 100 times in the station were chosen; the changes of their 5 parameters as RBC, Hb, Hct, PLT and WBC, as well as the correlation with the total number of platelet donations were analyzed through statistical analysis of the first 100 donations(10 donations/group). 【Results】 During 2 years, the hematological parameters were similar between 20-29 donation group(n=30) and 30-44 donation group(n=11) (P>0.05). For donors with donations≥100 occasions, RBC, Hb, Hct and WBC were negatively correlated with the number of blood donations, while Plt was positively correlated. There were significant differences in Hb, Hct, WBC and Plt among groups (P<0.05). Hb, Hct and WBC showed a downward trend, while Plt showed an upward trend. 【Conclusion】 With the increase of blood donations and units of blood donated, some changes in hematological parameters are observed among long-term high-frequency platelet donors. Monitoring and health education should be strengthened to ensure the safety and quality of blood donors.
