Objective To investigate the potential beneficial predictors for endovascular treatment(EVT)in case of acute anterior circulation large vessel occlusion with large-core infarction.Methods We made a retrospective inclusion of 92 patients with anterior circulation large vessel occlusion and core infarct volume ranging from 50 to 100 mL,who underwent EVT at Zhangzhou Municipal Hospital of Fujian Province from March 2018 to February 2021.All the patients were confirmed as anterior circulation large infarction and large infarct volume using computed tomography(CT),computed tomography angiography(CTA),and computed tomography perfusion(CTP)before EVT.All clinical and imaging data were collected to observe the postoperative recurrence rate,incidence of symptomatic intracranial hemorrhage(sICH),and functional prognosis 90 days.Then the patients were divided into favorable outcomes group(mRS≤3)and unfavorable outcomes group(mRS＞3)based on Rankin scores 90 days post-stroke.Univariate and multivariate Logistic analysis were conducted to analyze factors influencing the patients'prognosis.By combining the results of multivariate analysis,we constructed receiver operating characteristic(ROC)curves and identified the cut-off value to evaluate the predictive value of age for post-vascular treatment prognosis.Results Among the included patients,the postoperative revascularization rate(mTIICI≥2b)was 95％(88 cases),the rate of favorable outcomes at 90 days postoperatively(mRS≤3)was 32.61％(30 cases),the incidence of sICH was 13％,and the mortality rate was 31.5％.Compared with the unfavorable outcomes group,the favorable outcomes group had a younger age and a higher proportion of males.Multivariate analysis indicated that older age was an independent risk factor for adverse outcomes following endovascular treatment(OR=4.97,95％CI:1.78-13.90,P=0.002).The ROC curve indicated that the area under the curve was maximized at the age of 72.5 years(AUC=0.763,95％CI:0.661-0.864,P＜0.001).Its sensitivity and specificity was 0.565 and 0.833,respectively.Conclusion Age is an independent predictor of the prognosis of acute procirculatory large core stroke.Patients with large core infarction older than 72.5 years may not benefit from endovascular therapy,which needs to be confirmed by a multicenter large sample prospective randomized controlled trial.

Objective To explore the efficacy of blunt separation method in midline catheter intubation in elderly patients with coagulation dysfunction.Methods A total of 80 elderly patients with coagulation dysfunction were selected in the convenience sampling method from October 2022 to April 2023 in our hospital,and they were randomly divided into an experimental(blunt)group and a control(routine)group,with 40 patients in each group.The differences in the degree of bleeding and exudation at the puncture site,the pain score and the incidence of complications(including bleeding and exudation,phlebitis,symptomatic catheter-related thrombus,catheter blockage,catheter pulling-off)were compared between 2 groups.Results In the experimental group,the degree of bleeding and exudation at the puncture point immediately after the operation,degree of bleeding and exudation at the puncture point 24 hours after the operation,pain score 1 day after the catheterization,pain score 3 days after the catheterization,incidence of bleeding and exudation,total incidence of complications and maintenance times were significantly lower than these in the control group(P＜0.05).In terms of the pain score immediately after the operation,pain score 5 days after the operation,incidence of phlebitis,incidence of symptomatic catheter-related thrombosis,incidence of catheter blockage,incidence of catheter pulling-off,incidence of catheter related skin injury,incidence of unplanned extubation,success rate of one-time sheath delivery and the indwelling time,the differences between the experimental group and control group were not significant(P＜0.05).Conclusion The application of blunt separation method in midline catheter indwelling can significantly reduce the incidence and degree of bleeding at the puncture point,decrease the maintenance times and relieve the pain in elderly patients with coagulation dysfunction.

OBJECTIVE To investigate the risk factors for hypokalemia caused by amphotericin B liposome， and to provide reference for clinical use of drugs. METHODS A retrospective analysis was used to collect the information of patients who used amphotericin B liposome during the hospitalization in First Affiliated Hospital of Hainan Medical College from January 2012 to December 2021. The details of use information about amphotericin B liposome and the potassium supplementation were collected. The patients were divided into hypokalemia group and normal group according to the occurrence of hypokalemia. Univariate and multi-variate Logistic regression analyses were used to analyze the risk factors for hypokalemia induced by amphotericin B liposome. RESULTS Of the 121 patients included in this analysis， 60 patients were in hypokalemia group， 61 patients were in normal group. The following parameters of the hypokalemic group were significantly higher or longer than those of the normal group， such as the maintenance dose， cumulative dose and maximum daily dose （in patients with severe hypokalemia） of amphotericin B liposome， treatment days， the maintained days of hypokalemia， daily dose of potassium supplement （in patients with moderate or severe hypokalemia）， the duration of potassium supplement （in patients with moderate hypokalemia）. Results of single factor analysis showed that the cumulative dose of amphotericin B liposome ≥200 mg and the duration of treatment ≥5 days were independent risk factors of hypokalemia caused by this drug （P＜0.05）. Multi-variate analysis results showed that the presence of basic hypokalemia， body weight ＜50 kg， cumulative dose of amphotericin B liposome ≥200 mg and the duration of treatment ≥5 days were the independent risk factors for hypokalemia caused by amphotericin B liposome （P＜0.05）. CONCLUSIONS The incidence of hypokalemia caused by amphotericin B liposome is high， the independent risk factors for hypokalemia include cumulative dose ≥200 mg， treatment days ≥5 days， the presence of basic hypokalemia and body weight ＜ 50 kg. It is suggested that serum potassium should be elevated to normal level before amphotericin B liposome treatment， and the level of serum potassium should be monitored during medication to reduce the occurrence of hypokalemia.

ObjectiveTo investigate the overall level of professional identity, learning motivation and learning engagement in students majoring rehabilitation technology in higher vocational education, and to explore the relationship among them. MethodsFrom March to April, 2022, a questionnaire survey was conducted among 334 students majoring in rehabilitation technology in three public full-time higher vocational schools in Beijing, Shandong and Anhui with the Professional Identity Scale, Learning Motivation Scale and Learning Engagement Scale. ResultsA total of 334 valid questionnaires were collected. The average scores of professional identity, learning motivation and learning engagement were (3.64±0.66), (3.78±0.61) and (3.42±0.72), respectively. There was a significant positive correlation among them (r > 0.602, P < 0.01). The professional identity was different with schools and ages (P < 0.05), and the learning motivation was different with ages and grades (P < 0.01). There was no significant difference in learning engagement in different schools, genders, ages, or grades (P > 0.05). The learning motivation played a mediative role between professional recognition and learning engagement, accounting for about 55.3% of the total effect. ConclusionThe professional identity, learning motivation and learning engagement of the students majoring in rehabilitation technology in higher vocational colleges are at a moderate level, which needs to be improved. The professional identity is different among the schools of cities with different economic development, which suggests that there may be a decreasing effect of policy transmission behind it, which should be highly valued.

Objective:To analyze the clinical characteristics of adult Chinese patients with syncope.Methods:This is a cross-sectional survey study. Patients with preliminary diagnosis of syncope in the Emergency Department, Geriatrics and Cardiology Outpatient Department, or Syncope Unit of 37 hospitals in 19 provinces, autonomous regions and the Hong Kong Special Administrative Region from June 2018 to March 2021 were included in this study. The clinical features of these patients with syncope were analyzed.Results:A total of 4 950 consecutive patients with syncope were included in this study. The age was (56.3±16.8)years, and 2 604 cases (52.6%) were male. The most common type of syncope was neurally mediated syncope (2 345 (47.4%)), followed by cardiac syncope (1 085 (21.9%)), orthostatic hypotensive syncope (311 (6.3%)), and unexplained syncope accounted for nearly one third (1 155 (23.3%)). Predisposing syncope was more common in patients under 65 years of age(2 066(72.4%) vs. 786(27.6%),χ 2=136.5, P<0.001). Presyncope was more common in patients with neurally mediated syncope (1 972(79.0%) vs.1 908(73.9%), χ 2=17.756, P<0.001). Premonitory symptoms were more common in women(1 837(80.0%) vs. 1 863(73.0%),χ 2=33.432, P<0.001). Presyncope syndrome was more common in patients under 65 years of age (2 482(77.8%) vs. 1 218(73.4%),χ 2=17.523, P=0.001). Cyanosis was more common in ≥65 years old patients (271(18.2%) vs. 369(12.7%), χ 2=23.235, P<0.001). Urinary incontinence was more common in old patients aged ≥65 years(252(15.2%) vs. 345(10.8%), χ 2=19.313, P<0.001). Family history was more common in patients with cardiogenic syncope compared with other types of syncope (264(24.3%) vs. 754(19.5%), χ 2=11.899, P=0.001). Hypertention(1 480(30.5%)), coronary heart disease(1 057(21.4%)), atrial flutter and atrial fibrillation(359(7.2%)), second degree atrioventricular block(236(4.8%)) were common complications of syncope. The proportion of patients with coronary heart disease was significantly higher in cardiac syncope than that of other types of syncope(417(38.4%) vs. 640(16.6%), χ 2=241.376, P<0.001). Other common complications included cerebrovascular diseases (551 (11.1%)) and diabetes mellitus (632(12.8%)). Conclusions:Neurally mediated syncope is the most common syncope in adult Chinese population. Patients with predisposing conditions and premonitory conditions are younger. Presyncope is more common in women. The proportion of family history and coronary heart disease is higher in patients with cardiogenic syncope.

Objective:To investigate the associations of brain white matter integrity deficits, and to explore the association of fractional anisotropy (FA) abnormality with clinical symptoms and cognitive impairments, as well as the prediction effect of the FA alterations on symptoms and cognitive function outcomes in the acute stage of schizophrenia from the whole brain level based on magnetic resonance diffusion tensor imaging (DTI).Methods:From November 2019 to December 2020, thirty-eight patients with first-episode schizophrenia and 38 healthy controls were recruited in this study. Wisconsin card classification test (WCST), digit span test (DST forward/backward), verbal fluency test, Stroop (A/B/C), trail making test (TMT-A/B), as well as positive and negative syndrome scale (PANSS) were utilized to evaluate patients' cognitive function and clinical symptoms both before and after 8 weeks of risperidone monotherapy. T1-weighted images and DTI data of all the subjects were collected . FSL and SPM8 were used to preprocess MRI data and compare the between-group differences of FA. Support vector machine (SVM) analysis was used to evaluate the accuracy of abnormal FA values in differentiating schizophrenic patients from healthy controls. Finally, stepwise multiple regression analysis or generalized linear models were used to explore the associations between white matter integrity and symptoms or cognition.Results:Before treatment, patients' FA values of right medial temporal lobe (mTL), cuneus, anterior cingulate gyrus (ACG) and inferior parietal lobe (IPL) were significantly lower than those in healthy controls ( P<0.01, GRF corrected), and patients' FA values of bilateral middle cingulate gyrus (mCG) were significantly higher than those in the control group ( P<0.01, GRF corrected). SVM analysis showed that four combinations could distinguish the patients from the control with the most accurate rate of 89.47%. Patients' baseline decreased FA values in the right IPL were positively associated with their increased total response time in WCST ( β=0.489, P=0.003, FDR corrected), correct response time in WCST ( β=0.450, P=0.008, FDR corrected), error response time in WCST ( β=0.435, P=0.008, FDR corrected), TMT-B ( β=0.296, P=0.042, FDR corrected), Stroop-C ( β=0.345, P=0.035, FDR corrected), and PANSS-P ( β=0.321, P=0.042, FDR corrected). Reduced FA values in the right mTL in patient group were significantly negatively related to the total time spent on the TMT-A ( β=-0.425, P=0.009, FDR corrected) and TMT-B ( β=-0.325, P=0.026 with FDR correction). Increased FA values in right mCG in patient group demonstrated positive associations with total response time in the WCST ( β=0.585, P=0.002, FDR corrected), correct response time in WCST ( β=0.524, P=0.003, FDR corrected), error response time in WCST ( β=0.536, P=0.003, FDR corrected) and total time consuming in TMT-B ( β=0.484, P=0.004, FDR corrected), as well as negative associations with DST-forward ( β=-0.319, P=0.042, FDR corrected). After treatment, patients' percentage changes in total response time of WCST ( β=0.715, P<0.001, FDR corrected), correct response time of WCST ( β=0.752, P<0.001, FDR corrected), as well as total time-consuming of TMT-A ( β=1.333, P=0.001, FDR corrected) showed positive correlations with baseline increased FA values in the left mCG. Percentage alteration of Stroop-B was negatively correlated with baseline FA values in the right cuneus ( β=-0.745, P=0.015, FDR corrected). Conclusions:The combination of abnormal FA values in multiple brain regions may be potential biomarkers to distinguish schizophrenic patients from healthy volunteers. There was regional dependence in the associations of the impairment of white matter integrity with the cognitive impairment, the severity of psychopathological symptoms as well as the prognosis of patients in the acute stage.

Objective:To evaluate the value of combined measurement of urinary insulin-like growth factor-binding protein 7 (IGFBP7) and urinary metalloproteinase inhibitor-2 (TIMP-2) in the early diagnosis and prognosis of cardiac surgery-associated acute kidney injury (CSA-AKI).Methods:From March 2018 to June 2018, cardiac surgery patients admitted to the cardiac macrovascular surgery department of the First Affiliated Hospital of Nanjing Medical University were prospectively included, and the blood creatinine was monitored to observe the presence of acute kidney injury (AKI). The prognostic information of the patients was collected, including in-hospital dialysis, in-hospital death, complete recovery of kidney function at discharge, death in one year after surgery, and progression to chronic kidney disease. The levels of urine IGFBP7 and TIMP-2 at 6 h, 24 h and 48 h after cardiac surgery were detected by enzyme linked immunosorbent assay (ELISA), and the urine creatinine (Cr) was also measured. Moreover, receiver operating characteristic curves (ROC) were plotted and the areas under the curves ( AUC) were calculated to evaluate the predictive value and prognostic value of urinary [TIMP-2]·[IGFBP7] (T*I for short) and urine T*I/urine Cr 2 in CSA-AKI. Results:A total of 74 patients with age of (58.43±10.91) years old and 47 males, were enrolled in this study, of which 24 cases (32.4%) had AKI and 10 cases (13.5%) had stage 2-3 AKI. Compared with the non-AKI group, the AKI group had significantly higher levels of urine T*I levels at 6 h and 24 h (both P<0.05). The AUC of T*I at 24 h predicting for AKI was 0.71(95% CI 0.59-0.81, P=0.001, cutoff value 0.020, sensitivity 79.2%, specificity 56.0%), while the AUC for stage 2-3 AKI was 0.85 (95% CI 0.75-0.92, P<0.001, cutoff value 0.083, sensitivity 70.0%, specificity 90.6%). Urinary T*I normalized for urinary creatinine excretion did not show better predictive value. In addition, of T*I at 24 h predicting for poor hospitalization outcome, renal recovery, and one year postoperative death, the AUC was 0.82(95% CI 0.71-0.90, P=0.001), 0.80(95% CI 0.66-0.86, P<0.001), and 0.81(95% CI 0.70-0.89, P=0.047), respectively. Conclusion:The combined detection of TIMP-2 and IGFBP7 in urine is expected to be a biomarker for early diagnosis of CSA-AKI and has certain clinical value in predicting the prognosis of CSA-AKI.
