By analyzing the current application of multi-modal data in the diagnosis of gastric "inflammation-cancer" transformation， this study explored the feasibility and strategies for constructing a disease-syndrome integrated diagnosis and treatment system. Based on traditional Chinese medicine （TCM） phenomics， we proposed utilizing multi-modal data from literature research， cross-sectional studies， and cohort follow-ups， combined with artificial intelligence technology， to establish a multi-dimensional diagnostic and treatment index system. This approach aims to uncover the complex pathogenesis and transformation patterns of gastric "inflammation-cancer" progression. Additionally， by dynamically collecting TCM four-diagnostic information and modern medical diagnostic information through a long-term follow-up system， we developed three major modules including information extraction， multi-modal phenotypic modeling， and information output， to make it enable real-world clinical data-driven long-term follow-up and treatment of chronic atrophic gastritis. This system can provide technical support for clinical diagnosis， treatment evaluation， and research， while also offering insights and methods for intelligent TCM diagnosis.

Objective To explore the association of the magnitude of systolic blood pressure reduction(SBPr)with post-procedure 24 h symptomatic intracranial hemorrhage(sICH)and 90-day clinical outcomes in patients with successful endovascular thrombectomy(EVT).Methods Consecutively registered patients with EVT caused by anterior circulation large vessel occlusion stroke(LVOS)in the First Affiliated Hospital of Wannan Medical College(Yijishan Hospital)between July 2015 and April 2023 and patients with successful reperfusion were analyzed.Demographic data,medical history(hypertension,diabetes),the trial of Org 10172 in acute stroke treatment(TOAST)classification,the baseline National Institutes of Health Stroke Scale(NIHSS)score and the baseline Alberta stroke early CT(ASPECT)score of patients were collected.And procedure related parameters(including time from onset to puncture,time from onset to reperfusion,occluded site[internal carotid artery,M1 segment of middle cerebral artery,M2 segment of middle cerebral artery],collateral circulation status[determined based on preoperative occluded angiography showing the range of collateral circulation in the occluded vessel area,defined as good collateral circulation with a reflux range of ≥ 50％and poor collateral circulation with a reflux range of＜50％]),immediate postoperative reperfusion status(evaluated using the modified thrombolysis for cerebral infarction[mTICI]grading,successful reperfusion defined as mTICI grading of 2b-3),24 hours sICH,and 90 days clinical outcomes(evaluated using the modified Rankin scale score at 90days after EVT,with a score ≤ 2indicating a good prognosis and a score＞2indicating a poor prognosis).SBPr was defined as(baseline SBP-mean SBP)/baseline SBP x 100％.According to the the magnitude of SBPr,SBPr is divided into 5 categories(＜-10％,-10％-10％,＞10％-20％,＞20％-30％and＞30％).Based on the clinical outcomes at 90 days and the occurrence of sICH at 24 hours after EVT,patients were divided into a good prognosis group and a poor prognosis group,as well as an sICH group and a non-sICH group.The relationship between SBPr and postoperative 90 days clinical prognosis or sICH was analyzed using a binary Logistic regression model.Subgroup analysis was conducted based on a history of hypertension(yes and no),continuous intravenous hypotensive therapy(yes and no),baseline ASPECT scores(3-5 and 6-10),and collateral circulation status(good and bad).Using a restricted cubic plot to depict the relationship between SBPr and sICH and clinical prognosis at 90days.Results(1)In total,731 patients were included.The median age was 71(62,77)years and 424(58.0％)were men.The median baseline NIHSS score was 14(12,18),the median baseline ASPECT was 9(7,10),405(55.4％)patients achieved 90-day modified Rankin scale score 0-2,and 35 patients(4.8％)developed sICH.(2)Multivariate analysis showed that the older age(OR,1.036,95％CI 1.017-1.056),the higher baseline NIHSS score(OR,1.095,95％CI1.049-1.144),the lower baseline ASPECT score(OR,0.704,95％CI 0.636-0.780),diabetes(OR,1.729,95％CI 1.084-2.758),bad collateral circulation(good collateral circulation vs.bad collateral circulation,OR,0.481,95％CI 0.332-0.696)and SBPr＞30％(SBPr-10％-10％as a reference,OR,2.238,95％CI 1.230-4.071),the higher the risk of poor clinical outcomes at 90 days(all P＜0.05).Continuous intravenous hypotensive therapy is a risk factor for postoperative 24 h sICH(OR,2.278,95％CI 1.047-4.953;P=0.038),while SBPr 20％-30％is associated with a lower risk of postoperative 24 h sICH(SBPr-10％-10％as a reference,OR,0.362,95％CI0.131-0.998;P=0.049).(3)The restrictive cube plot shows that there is a U-shaped relationship between SBPr after EVT and poor clinical outcomes at 90 days,while there is a nearly linear relationship with the occurrence of sICH.The more SBP reduction,the lower the incidence of sICH.(4)In the subgroup analyses,in the non-hypertension history and the good collateral circulation group,SBPr＞30％has a higher risk of poor clinical outcomes compared to SBPr-10％-10％(OR and 95％CI were 2.921[1.000-8.528]and 2.363[1.078-5.183],respectively,with P=0.05 or P＜0.05);After EVT,the group receiving continuous intravenous hypotensive therapy and the baseline ASPECT score 6-10 groups showed a significant correlation between SBPr＞30％and poor clinical outcomes at 90 days(SBPr-10％-10％as a reference,OR and 95％CI were 2.646[1.168-5.993]and 2.481[1.360-4.527],respectively,with P＜0.05).The correlation between SBPr and lower incidence of sICH was only found in the subgroup of poor collateral circulation(SBPr-10％-10％as a reference,SBPr＞20％-30％:OR,0.133,95％CI 0.027-0.652;SBPr＞30％:OR,0.104,95％CI 0.013-0.864;all P＜0.05).Conclusions Among patients who achieved successful reperfusion with EVT,SBPr might be related to a worse functional outcome at 90 days and sICH 24 h after operation.However,the relationship may exhibit significant heterogeneity across different subgroups.Baseline ASPECT score,history of hypertension,collateral circulation,and the use of continuous venous hypertension after EVT have been highlighted in individualized blood pressure management after EVT.

Objective:To investigate the clinical outcome of endovascular treatment vs. drug treatment in patients with symptomatic non-acute long-segment occlusion of the internal carotid artery. Methods:Based on prospective cohort registration research data, patients with symptomatic non-acute long-segment occlusion of internal carotid artery were retrospectively included. They were divided into a drug treatment group and an endovascular treatment group according to the actual treatment received. The latter was further divided into a successful recanalization group and an unsuccessful recanalization group. The endpoint events included ipsilateral ischemic stroke, any stroke, and all-cause death. Multivariate logistic regression analysis was used to compare the endpoint events between groups during the perioprocedural period (within 30 days), and multivariate Cox proportional hazards model was use to compare the endpoint events between the groups during the long-term follow-up. Results:A total of 684 patients were included, of which 570 (83.33%) were male, median aged 63 years (interquartile range, 56-70 years). Three hundred and fifty-three patients (51.6%) received drug treatment; 331 (48.4%) received endovascular treatment, of which 161 (48.6%) had successful recanalization. The median follow-up time was 1 223 days (interquartile range, 646.5-2 082 days), with 109 patients (15.9%) experiencing stroke recurrence events (including 87 ipsilateral ischemic stroke) and 78 (11.4%) experiencing all-cause mortality. The risk of any stroke during the perioprocedural period in the successful recanalization group was significantly higher than that in the drug treatment group (odds ratio 3.679, 95% confidence interval 1.038-13.036; P=0.044), but the risk of ipsilateral ischemic stroke recurrence (risk ratio 0.347, 95% confidence interval 0.152-0.791; P=0.012) and all-cause mortality (risk ratio 0.239, 95% confidence interval 0.093-0.618; P=0.003) during the long-term follow-up were significantly lower than those in the drug treatment group. Conclusions:In patients with symptomatic non-acute long-segment occlusion of the internal carotid artery, endovascular treatment can increase the risk of stroke recurrence within 30 days, but successful recanalization can reduce the risks of long-term ipsilateral ischemic stroke recurrence and all-cause mortality.

Objective To investigate the influencing factors for acute multiple vessels occlusion(MVO)and its impact on the prognosis of patients with anterior circulation acute large vessel occlusion stroke(ALVOS)who achieved successful recanalization after endovascular treatment(EVT).Methods Patients with anterior circulation ALVOS who received successful EVT at the Yijishan Hospital of Wannan Medical College between July 2015 and April 2023 were retrospectively analyzed.Baseline data,including age,sex,onset-to-puncture time(OTP),onset-to-recanalization time(OTR),medical history(including atrial fibrillation,diabetes,hypertension),alcohol and smoking history,admission blood pressure(systolic and diastolic),Alberta stroke program early CT score(ASPECTS),National Institutes of Health stroke scale(NIHSS)score,trial of Org 10172 in acute stroke treatment(TOAST)classification(atherosclerotic type,cardioembolic type,and other etiology types),and 90-day modified Rankin scale(mRS)score were collected.Collateral circulation was assessed based on the degree of contrast agent reflux observed in the occluded arterial supply area during delayed DSA,and patients were classified into poor and good collateral circulation groups.Malignant cerebral edema was defined as a midline shift of ≥5 mm on the follow-up CT scan performed on day 3 post-surgery.The primary endpoint(efficacy indicator)was the 90-day mRS score,with mRS score≤ 2 considered as a good prognosis and mRS score＞2 considered as a poor prognosis.The secondary endpoint(safety indicator)was the 90-day mortality rate.All patients were divided into MVO and non-MVO groups based on whether they had single or multiple intracranial vessel occlusions.Acute MVO was defined as the detection of acute occlusion of other large or medium vessels,in addition to the main vessels(internal carotid artery or M1/M2 segments of the middle crebral artery[MCA]),in CT angiography,MR angiography,or DSA,resulting in ischemia in brain regions distinct from the main occlusion area.Factors that showed statistically significant differences in univariate analysis were further analyzed using multivariate Logistic regression to identify the risk factors for the occurrence of acute MVO and the factors associated with the prognosis of ALVOS patients.Results A total of 846 patients with ALVOS were included,with ages ranging from 26 to 94 years(mean age[69±11]years).The proportion of male patients was 57.2％(484/846).The median admission ASPECTS was 8(7,9)and the median admission NIHSS score was 14(12,18).The incidence of malignant cerebral edema at 3 days post-surgery was 13.4％(112/835),and the 90-day mortality rate was 19.1％(162/846).(1)Among the 846 ALVOS patients,810(95.7％)were in the non-MVO group and 36(4.3％)were in the MVO group.Univariate analysis showed significant differences between the MVO and non-MVO groups in terms of atrial fibrillation,malignant cerebral edema,admission ASPECTS,admission NIHSS scores,TOAST classification,collateral circulation,rate of complete recanalization,and 90-day poor prognosis rate(all P＜0.05).However,there was no statistically significant difference in 90-day mortality between the two groups(P=0.193).Multivariate Logistic regression analysis showed that TOAST classification of cardioembolic type(OR,16.089,95％CI 1.835-141.061,P=0.012)and other etiology types(OR,9.768,95％CI 1.078-88.540,P=0.043)were associated with the occurrence of MVO.(2)Among the 846 ALVOS patients,445 had a good prognosis at 90days,and 401 had a poor prognosis.Univariate analysis showed that,compared to the good prognosis group,the poor prognosis group had a lower proportion of males and smokers,and a higher proportion of patients with older age,higher baseline systolic blood pressure,hypertension,diabetes,and atrial fibrillation(all P＜0.01).Additionally,the poor prognosis group had higher admission NIHSS scores(P＜0.01),lower admission ASPECTS,lower rates of good collateral circulation and complete recanalization,higher rates of malignant cerebral edema and MVO,and statistically significant differences in TOAST classification distribution(all P＜0.01).Multivariate Logistic regression analysis showed that MVO was associated with poor 90-day prognosis in ALVOS patients after EVT(OR,3.368,95％CI 1.149-9.878,P=0.027).Furthermore,older age(OR,1.045,95％CI 1.025-1.066),diabetes(OR,1.719,95％CI 1.080-2.734),higher baseline systolic blood pressure(OR,1.012,95％CI 1.004-1.019),lower admission ASPECTS(OR,0.746,95％CI 0.674-0.826),higher admission NIHSS score(OR,1.115,95％CI 1.070-1.162),without immediate postoperative complete recanalization(OR,0.413,95％CI 0.290-0.592),poor collateral circulation(OR,0.594,95％CI 0.415-0.851),and malignant cerebral edema(OR,6.191,95％CI 3.026-12.670)were all associated with poor 90-day prognosis after EVT in ALVOS patients(all P＜0.05).Conclusions The TOAST classification of cardioembolic type and other etiology types is associated with MVO.MVO is a risk factor for poor outcomes after successful EVT in ALVOS patients.

Objective Using the concept of allostatic load(AL)to evaluate aging of male SD rats and the effectiveness of Zuogui Pill in naturally aging rats.Methods Naturally aging male SD rats were tested at the ages of 2,5,8,14,18,and 21 months.They were divided into an elderly control group,low-dose Zuogui Pill group,and high-dose Zuogui Pill group.Intervention with Zuogui Pill was trialed for 3 months.Blood samples were taken from the tails of rats each month,and the number of T lymphocytes and rate of apoptosis were measured by flow cytometry.Low-density lipoprotein cholesterol(LDL-c),high-density lipoprotein cholesterol(HDL-c),triglycerides(TG),total cholesterol(TC),free fatty acids(FFA),25 hydroxyvitamin D(25-OH-D),corticosterone(CORT),C-reactive protein(CRP),and interleukin-6(IL-6)were detected in rat sera.By identifying the collinearity between indicators and professional considerations,LDL-c,TC,HDL-c,FFA,TG,CORT,IL-6,CRP,25-OH-D,CD3+T cell count,and CD3+T cell apoptosis rate were included in the AL scoring.The threshold for each indicator was established with data from 5-month-old rats,and the score was 1 point below or/and above the threshold.Results The serum levels of LDL-c,TG,TC,25-OH-D,CRP,and IL-6 of rats showed significant changes with age,although the patterns of change differed.The CD3+T lymphocyte count significantly decreased with age(P＜0.01),while the apoptosis rates of CD3+,CD4+,and CD8+T lymphocytes significantly increased with age(P＜0.01).Zuogui Pill significantly increased serum CORT levels in elderly rats(P＜0.01)and reduced the apoptosis rate of CD8+T lymphocytes(P＜0.05).The AL score began to increase in rats at 5 months of age and reached its peak in those of 18 months of age.Conclusions AL can better characterize the aging process compared to a single indicator.Zuogui Pill can improve the stress response ability of aging rats and alleviate immunosenescence.

Objective:To observe the surgical methods and clinical efficacy on reconstruction of digital flexion function using transfer of modified free gracilis myocutaneous flap.Methods:Between March 2014 and August 2022, 7 male patients, aged between 23 and 38 (average age 28) years old, were treated by reconstruction of forearm flexor function using modified free gracilis myocutaneous flap transfer to overcome the dysfunction in the Department of Hand and Foot Surgery, Zhejiang Rongjun Hospital. After the scar excision, the defects in forearm ranged from 15.0 cm × 4.5 cm to 28.0 cm × 6.5 cm, with flap excision areas of 17.0 cm × 5.5 cm to 30.0 cm × 8.0 cm. The nerve carried by the myocutaneous flap was anastomosed with the musculi branch of the median nerve, and the perforator artery and vein of the gracilis muscle were anastomosed with the brachial artery or the branch of ulnar artery and radial artery. Six patients had the flap donor sites directly closed primarily. A medium-thickness skin graft was taken from the ipsilateral groin area in 1 patient, to cover the remaining wound after the primary closure for wound reduction. Postoperative clinical efficacy was monitored through the follow-ups via visits of outpatient clinic, telephone calls or WeChat interviews.Results:After surgery, 1 patient experienced a vascular compromise of the flap, which was resolved after reanastomosis. One patient had a necrotic in distal flap about 2.0 cm×1.0 cm in size, which healed after dressing change. All other 5 flaps survived successfully. The postoperative follow-up ranged from 12 to 36 months, at 18 months in average. The flaps had good appearance and texture. Protective sensation recovered to varying degrees at 6 months after surgery. At 2 years after surgery, all of 7 patients showed significant improvement in hand and forearm appearance, along with restored finger flexion, grasping and partial hand function. According to the Evaluation Standard of Upper Limb Functional of Hand Surgery of Chinese Medical Association, flexion function recovered to excellent in 1 patient, good in 3 patients and fair in 3 patients. In the donor sites, there were only linear scars or mild pigmentation without significant loss of function.Conclusion:A modified free gracilis myocutaneous flap transfer is used to reconstruct digit flexion function. The procedure is safe and reliable, with a quick and relatively postoperative and satisfactory recovery in forearm flexion function, hence makes it an ideal surgical technique for reconstruction of digit flexion function.

ObjectiveTo systematically evaluate the efficacy and safety of Tianmeng Oral Liquid in the treatment of hyperprolactinemia caused by antipsychotics in female patients with schizophrenia， and to provide references for intervention of antipsychotic-induced hyperprolactinemia patients. MethodsEnglish databases （PubMed， Cochrane Library， PsycINFO and Embase） and Chinese databases （CNKI and Wanfang） were systematically searched， with a search time frame of the period from database creation to September 16， 2022. Randomized controlled studies （RCTs） on adjunctive Tianmeng Oral Liquid in the treatment of hyperprolactinemia caused by antipsychotics in female patients with schizophrenia were included. Three investigators independently screened the literatures and extracted data according to PICOS principles and evaluated the quality of including literatures， and the Meta-analysis was performed by using RevMan 5.3. ResultsA total of 3 articles including 256 female schizophrenic patients with hyperprolactinemia were included. Meta-analysis results showed that at the treatment endpoint， the improvement of hyperprolactinemia symptoms reported a significant superiority of the intervention group than the control group （RR=1.73， 95% CI： 1.07~2.79， P˂0.05）. Similarly， the significant superiority of the intervention group than the control group were also found in reducing serum prolactin levels （WMD=-55.17， 95% CI： -68.16~-42.18， P<0.01） and Positive and Negative Syndrome Scale （PANSS） total scores were lower in the intervention group than in the control group （WMD=-7.36， 95% CI： -8.94~-5.77， P<0.01）. ConclusionTianmeng Oral Liquid may help improve clinical efficacy and reduce serum prolactin levels in female schizophrenia patients with hyperprolactinemia. It may improve psychiatric symptoms in female patients with schizophrenia.

Objective:To investigate the influencing factors, periprocedural complications, and long-term outcomes of successful recanalization after endovascular treatment in patients with non-acute symptomatic internal carotid artery occlusion.Methods:Patients with non-acute internal carotid artery occlusion received endovascular treatment in the Nanjing Stroke Registration System between January 2010 and December 2021 were retrospectively enrolled. Clinical endpoint events were defined as successful vascular recanalization, periprocedural complications (symptomatic embolism and symptomatic intracranial hemorrhage), neurological function improvement, and recurrence of ipsilateral ischemic events. Multivariate logistic regression analysis was used to investigate the independent influencing factors of successful vascular recanalization. Cox proportional hazards regression analysis was used to investigate the correlation between endovascular treatment outcomes and neurological function improvement, as well as ipsilateral ischemic cerebrovascular events. Results:A total of 296 patients were included, of which 190 (64.2%) were successfully recanalized. Multivariate logistic regression analysis showed that symptoms manifest as ischemic stroke (odds ratio [ OR] 3.353, 95% confidence interval [ CI] 1.399-8.038; P=0.007), the time from the most recent symptom onset to endovascular therapy within 1 to 30 d ( OR 2.327, 95% CI 1.271-4.261; P=0.006), proximal conical residual cavity ( OR 2.853, 95% CI 1.242-6.552; P=0.013) and focal occlusion (C1-C2: OR 3.255, 95% CI 1.296-8.027, P=0.012; C6/C7: OR 5.079, 95% CI 1.334-19.334; P=0.017) were the independent influencing factors for successful vascular recanalization. Successful recanalization did not increase the risk of symptomatic intracranial hemorrhage within 7 d after procedure (3.2% vs. 0.9%; P=0.428). The median follow-up time after procedure was 38 months. Cox proportional hazards regression analysis showed that after adjusting for confounding factors, successful recanalization was significantly associated with postprocedural neurological improvement (hazard ratio 1.608, 95% CI 1.091-2.371; P=0.017), and significantly reduced the risk of recurrence of long-term ischemic events (hazard ratio 0.351, 95% CI 0.162-0.773; P=0.010). Conclusion:In patients with non-acute internal carotid artery occlusion, successful endovascular recanalization can effectively reduce the risk of long-term ischemic events without increasing the risk of symptomatic intracranial hemorrhage.

Objective:To investigate predictive factors for successful endovascular recanalization in patients with non-acute symptomatic internal carotid artery occlusion (SICAO), to develop a decision tree model using the Classification and Regression Tree (CART) algorithm, and to evaluate the predictive performance of the model.Methods:Patients with non-acute SICAO received endovascular therapy at 8 comprehensive stroke centers in China were included retrospectively. They were randomly assigned to a training set and a validation set. In the training set, the least absolute shrinkage and selection operator (LASSO) algorithm was used to screen important variables, and a decision tree prediction model was constructed based on CART algorithm. The model was evaluated using the receiver operating characteristic (ROC) curve, Hosmer-Lemeshow goodness-of-fit test and confusion matrix in the validation set.Results:A total of 511 patients with non-acute SICAO were included. They were randomly divided into a training set ( n=357) and a validation set ( n=154) in a 7:3 ratio. The successful recanalization rates after endovascular therapy were 58.8% and 58.4%, respectively. There was no statistically significant difference ( χ2=0.007, P=0.936). A CART decision tree model consisting of 5 variables, 5 layers and 9 classification rules was constructed using the six non-zero-coefficient variables selected by LASSO regression. The predictive factors for successful recanalization included fewer occluded segments, proximal tapered stump, ASITN/SIR collateral grading of 1-2, ischemic stroke, and a recent event to endovascular therapy time of 1-30 d. ROC analysis showed that the area under curve of the decision tree model in the training set was 0.810 (95% confidence interval 0.764-0.857), and the optimal cut-off value for predicting successful recanalization was 0.71. The area under curve in the validation set was 0.763 (95% confidence interval 0.687-0.839). The accuracy was 70.1%, precision was 81.4%, sensitivity was 63.3%, and specificity was 79.7%. The Hosmer-Lemeshow test in both groups showed P>0.05. Conclusion:Based on the type of ischemic event, the time from the latest event to endovascular therapy, proximal stump morphology, the number of occluded segments, and the ASITN/SIR collateral grading constructed the decision tree model can effectively predict successful recanalization after non-acute SICAO endovascular therapy.

Objective:To evaluate the safety and efficacy of endovascular thrombectomy (EVT) in acute anterior circulation large vessel occlusive stroke (ALVOS) and explore the related influencing factors for prognoses in patients with low Alberta Stroke Program Early Computed Tomography Score (ASPECT).Methods:Patients with acute ALVOS who underwent EVT in Yijishan Hospital of Wannan Medical College from January 2019 to June 2022 were sequentially enrolled. (1) Patients were divided into a low ASPECT group (0-5) and a non-low ASPECT group (6-10), and the differences between the two groups were compared with respect to incidence of perioperative complications and good prognosis rate [modified Rankin scale (mRS) score≤2] 90 days after onset. (2) According to the prognoses 90 days after onset, the low ASPECT group was divided into the good prognosis (mRS score≤2) and poor prognosis (mRS score>2) subgroup. Univariate analysis and multivariate logistic regression analysis were used to investigate the independent risk factors for prognoses of the low ASPECT patients after EVT.Results:A total of 582 patients [age 26-94(69±11) years, 345 male patients (59.3%)] were enrolled for analysis. The baseline ASPECT score was 8 (7, 10), and the baseline NIHSS score was 14 (11, 18). Among them, 102 (17.5%) patients were in the low ASPECT score group and 480 (82.5%) patients were in the non-low ASPECT score group. In the total cohort, patients in the low ASPECT score group had a higher incidence of symptomatic intracranial hemorrhage, lower 90-day good prognosis rate, and higher 90-day mortality rate. Further, propensity score matching statistical analysis showed that patients in the low ASPECT score group had a significantly higher incidence of malignant brain edema after EVT treatment (40.0% vs. 17.6%, χ2=9.13, P=0.003), and a significantly lower 90-day good prognosis rate (24.7% vs. 41.6%, χ2=4.96, P=0.026), but there was no significant difference in the incidence of symptomatic intracranial hemorrhage and 90-day mortality between the two groups (40.3% vs. 26.0%, χ2=3.55, P=0.060). Among 102 patients with low ASPECT score, 22 (21.6%) patients had good prognosis and 80 (78.4%) had poor prognosis. Multivariate logistic regression analysis showed that history of atrial fibrillation ( OR=4.478, 95% CI 1.186-16.913, P=0.027) was an independent risk factor for poor prognosis of EVT in patients with low ASPECT score, while good collateral circulation (grade 2 vs. grade 0: OR=0.206, 95% CI 0.051-0.842, P=0.028) was a protective factor for good prognosis of EVT in patients with low ASPECT score. Conclusions:Although the 90-day good prognosis rate of EVT treatment for patients with low ASPECT score was lower than that of the non-low ASPECT group, 21.6% patients still benefitted from EVT treatment, especially patients with non-atrial fibrillation and good collateral circulation. Future studies involving more patients are needed to validate our observations.
