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.

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.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

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.

Cryptogenic stroke refers to ischemic stroke that is not clear to the cause of the disease through routine examinations. With the development of medical technology, studies have found that most cryptogenic stroke is caused by embolism.Therefore,the concept of embolic stroke of undetermined source (ESUS) is proposed. The main causes of ESUS include subclinical atrial fibrillation, patent foramen ovale, aortic arch atherosclerotic plaque, non-stenotic complex carotid atherosclerotic plaques, and tumor-related embolism, etc. This article reviews the etiology and secondary prevention of ESUS.
