RESUMEN
Background and Purpose: To evaluate the predictive power of the China-PAR model for cardiovascular disease (CVD).Methods: Dominate databases, including PubMed, Web of Science, CNKI, Wanfang Data Knowledge Service Platform, Chinese Biomedical Literature Service System, and VIP self-built database, were searched from January 1, 2016 to February 22, 2022. The primary outcome included observed events and predicted events by China-PAR. Meta-analysis was performed using RevMan 5.3 software. Stroke, arteriosclerotic cardiovascular disease (ASCVD), male, and female were divided into subgroup analyses. Funnel plots were used to assess publication bias.Results: A total of nine studies, which included 221,918 participants, were analyzed. Meta-analysis showed the combined observed incidence of CVD was 3.97%, and the combined predicted incidence was 9.59% by China-PAR. There was no significant difference between the observed and the predicted events. Subgroup analysis showed there was no statistical significance between the observed and the predicted events for stroke or for ASCVD. The difference between the observed and the predicted events by China-PAR was not statistically significant in either males or females.Conclusions: China-PAR model has important public health significance to further improve the primary prevention strategy of CVD.

Numb regulates cell proliferation and differentiation through endocytosis and ubiquitination of signaling molecules. Besides, Numb controls the migration of epithelial cells by regulating intercellular junctions. Studies have shown that Numb promotes or inhibits tumor progression in different tumors. However, its role and mechanism in colorectal cancer remain unclear. We found that the expression level of Numb in colon tumor tissues has a great variety in different patients. Numb expression was negatively correlated with TNM stage and lymph node metastasis but positively correlated with tumor size. Elevated expression of Numb was associated with a good prognosis. Inhibiting Numb expression promoted the migration and invasion of colon cancer cells induced by TGF-ß, up-regulated the expression of EMT-related molecule Snail, and prevented the expression of E-cadherin. We also found that Numb promoted the proliferation and clones formation while inhibiting colon cancer cells' late apoptosis. In addition, Numb inhibited the RhoA activation and ROCK inhibitor Y-27632 or interfered with ROCK expression, partially inhibiting Numb-regulated cell proliferation and migration. In vivo tumorigenesis assay in nude mice also found that Numb promoted the proliferation of colon cancer cells, inhibited the expression of E-cadherin, and strengthened the expression of Snail. In conclusion, our study found that Numb plays multiple roles in the occurrence and progression of colon cancer by regulating the RhoA/ROCK signaling pathway, which provides a new theoretical molecular basis for the pathogenesis of colon cancer.

BACKGROUND: The mastery and application of the "Plan-Do-Check-Act" (PDCA) cycle by hospital clinical department managers are essential for hospitals to carry out total quality management and continuously improve medical quality. This study investigated the degree of cognition of the PDCA cycle by clinical department managers and the factors affecting their cognition. METHODS: A self-designed questionnaire was used to evaluate the cognition of clinical department managers regarding the PDCA cycle in 11 municipal public Class III Grade A hospitals in Western China. RESULTS: More than 25% of clinical department managers in the surveyed hospitals are unaware or partially aware of the PDCA cycle. Logistic regression analysis showed that sex (P = 0.049), education (P < 0.001), duty (P < 0.001), and tenure (P = 0.002) had a significant influence on managers' cognition of PDCA. Participants who were female (P < 0.001), undergraduate (P < 0.001), head nurses, or deputy head nurses (P < 0.001), with a tenure of 5-10 years (P = 0.024) had a better cognition of the PDCA cycle. In the daily management of the department, the vast majority of managers do not implement the Check and Action steps. Among the trained managers, only 65.44% applied the complete PDCA cycle in daily management. Nearly a third of managers thought PDCA was a response to hospital demands; 82.83% of the managers need to receive PDCA cycle training, and half of them indicated a preference for online training. CONCLUSIONS: The cognition level of hospital clinical department managers regarding the PDCA cycle is relatively low, especially among the clinical department heads, and most of them are willing to accept PDCA cycle training.

BACKGROUND: Stroke is a leading cause of death and disability globally. A large proportion of ischemic strokes are caused by carotid atherosclerotic plaques. However, the relationship between vascular health status (arterial stiffness and endothelial dysfunction) and carotid plaque remains unclear. OUR STRATEGY: Here, we recruited 991 subjects with carotid plaques and 1170 subjects without carotid plaques to measure arterial stiffness and endothelial dysfunction, using a logistic regression model and multiple linear regression models to predict the relationship between them and carotid plaques. MAIN RESULTS: The data revealed that patients with carotid plaques presented a significantly higher mean of cf-PWV and lower mean RHI values. Age, male gender, diabetes, hypertension, and smoking contributed to plaque formation. Carotid plaques and their lengths were negatively associated with RHI values and positively associated with cf-PWV values; diabetes combined with hypertension showed a cumulative effect on arteriosclerosis. CONCLUSION: RHI combined with cf-PWV could improve the efficacy of predicting the presence of carotid plaques and their lengths.

BACKGROUND: This study aimed to investigate the risk predictors for early neurological deterioration (END) in isolated acute pontine infarction without any causative artery stenosis. METHODS: In this retrospective study, patients with isolated acute pontine infarction within 72 h of symptom onset were enrolled between October 2017 and December 2021. END was defined as an increase in the National Institutes of Health Stroke Scale (NIHSS) score ≥ 2 points within the first week postadmission. Patients were divided into the END and the non-END groups. Multiple logistic regression analysis was used to evaluate independent predictors of END in patients with isolated acute pontine infarction. RESULTS: A total of 153 patients were included in the final study (62 females; mean age, 67.27 ± 11.35 years), of whom 28.7% (47 of 153) experienced END. Multiple logistic regression analyses showed that infarct volume (adjusted odds ratio [aOR], 1.003; 95% CI, 1.001-1.005; P = 0.002) and basilar artery branch disease (aOR, 3.388; 95% CI, 1.102-10.417; P = 0.033) were associated with END. The combined ROC analysis of the infarct volume and basilar artery branch disease for predicting END showed that the sensitivity and specificity were 80.9% and 72.6%, respectively. CONCLUSION: Basilar artery branch disease and infarct volume were associated with END in acute isolated pontine infarction and may be useful prognostic factors for neurological progression.

BACKGROUND: Prevention and treatment of stroke are extremely important to reduce the incidence of stroke-related disability and the associated death. This study aimed to investigate the current ability of community doctors in stroke management in the Jinjiang district of Chengdu, China, and the effect of intensive education on stroke prevention and management ability of these doctors. METHODS: A self-designed questionnaire was used to investigate the current status of stroke management by community doctors in the Jinjiang district. Subsequently, a series of intensive stroke management education courses for community doctors was designed according to the relevant guidelines for cerebrovascular accident prevention and treatment in China. All community doctors were trained, and their ability to treat and prevent stroke was reassessed using the self-designed questionnaire. RESULTS: Of the 450 questionnaires issued, 370 (82.2%) and 389 (86.4%) community doctors were enrolled before and after intensive education, respectively. The results showed that only 37.8% of the community doctors in the Jinjiang district knew the guidelines for the prevention and treatment of cerebrovascular diseases, and only 45.9% thought they had stroke management ability. The stroke management ability of community doctors improved after intensive education (p < 0.05), including pre-hospital identification and management of stroke, and management of its risk factors. CONCLUSIONS: The capacity of community doctors in the Jinjiang district of Chengdu is far from meeting the requirements of stroke prevention and treatment. However, the stroke management ability of the community doctors was greatly improved by promoting intensive education.

OBJECTIVE: To compare the difference in the risk of stroke for four kinds of carotid artery plaque and carotid artery stenosis. METHODS: Literature was collected by searching the PubMed, Embase, Cochrane library and Ovid databases up to June 2022, using the free search terms "carotid plaque" and "stroke". Meta-analysis was performed on the selected articles using Stata16 to analyse the relationship of stroke risk factors. RESULTS: A total of 11 studies including 6661 participants were included. Meta-analysis results showed that the incidence of stroke was statistically significantly different between IPH (intraplaque haemorrhage) plaques and LRNC (lipid-rich necrotic core) plaques (RR: 1.27, 95% CI: 1.04-1.55, P < 0.05) and IPH plaques and calcification plaques (RR: 2.99, 95% CI: 1.74-5.14, P < 0.0001). Furthermore, there was a statistically significant difference between TRFC (thinned or ruptured fibrous caps) plaques and carotid artery stenosis (RR: 10.84, 95% CI: 5.60-20.98, P < 0.0001) and calcification plaques and carotid artery stenosis (RR: 0.83, 95% CI: 0.75-0.92, P < 0.0001). However, there was no statistically significant difference between the IPH and carotid artery stenosis (RR: 1.55, 95% CI: 0.68-3.52, P > 0.05), LRNC and TRFC (RR: 0.80, 95% CI: 0.11-5.82, P > 0.05), LRNC and calcification (RR: 1.81, 95% CI: 0.90-3.66, P > 0.05) and LRNC and carotid artery stenosis (RR: 1.40, 95% CI: 0.69-2.81, P > 0.05). CONCLUSION: IPH was associated with a higher incidence of stroke compared to LRNC and calcification plaques and TRFC has a higher risk of stroke than calcification plaques and carotid stenosis. This evidence suggests that IPH and TRFC may play an important role in predicting stroke.

BACKGROUND: Patients with acute large vessel occlusion (LVO) presenting with minor stroke are at risk of early neurological deterioration (END). The present study aimed to evaluate the frequency and potential predictors of END in patients with medical management and LVO presenting with minor stroke. The relationship between SVS length and END was also investigated. METHODS: This was a prospective multicenter study. Consecutive patients were collected with anterior circulation. LVO presented with minor stroke [National Institutes of Health Stroke Scale (NIHSS) ≤ 4] within 24 h following onset. END was defined as a deterioration of NIHSS ≥4 within 24 h, without parenchymal hemorrhage. The length of the susceptibility vessel sign (SVS) was measured using the T2* gradient echo imaging. RESULTS: A total of 134 consecutive patients with anterior circulation LVO presenting with minor stroke were included. A total of 27 (20.15%) patients experienced END following admission. Patients with END exhibited longer SVS and higher baseline glucose levels compared with subjects lacking END (P < 0.05). ROC curve analysis indicated that the optimal cutoff point SVS length for END was SVS ≥ 9.45 mm. Multivariable analysis indicated that longer SVS [adjusted odds ratio (aOR), 2.03; 95% confidence interval (CI), 1.45-2.84; P < 0.001] and higher baseline glucose (aOR,1.02; 95% CI, 1.01-1.03; P = 0.009) levels were associated with increased risk of END. When SVS ≥ 9.45 mm was used in the multivariate logistic regression, SVS ≥ 9.45 mm (aOR, 5.41; 95%CI, 1.00-29.27; P = 0.001) and higher baseline glucose [aOR1.01; 95%CI, 1.00-1.03; P = 0.021] were associated with increased risk of END. CONCLUSIONS: END was frequent in the minor stroke patients with large vessel occlusion, whereas longer SVS and higher baseline glucose were associated with increased risk of END. SVS ≥ 9.45 mm was a powerful independent predictor of END.

BACKGROUND: The high morbidity, mortality, and disability rates of stroke constitute a heavy burden to the society. The level of understanding about stroke warning symptoms and first aid systems among community residents was generally low. The aim of our work is to investigate stroke-related knowledge in community residents of Jinjiang district of Chengdu and to raise public awareness about stroke through an intensive educational program. METHODS: Nine communities in Jinjiang district were sampled and a questionnaire about stroke-related knowledge was applied before and after stroke educational activities. We analyzed the impact of such activities in stroke recognition and management. RESULTS: We collected 1685 valid questionnaires. The awareness about stroke risk before educational activities was 11.4%. The recognition of stroke warning signs among community residents was 29.8-59.5%. Among them, the recognition of major signs, such as limb weakness, language disorder, and imbalance was more than 50%. When faced with five stroke warning signs, the proportion of participants who chose to make an emergency call was 41.5%. Less than 10% of the participants chose to consult a doctor, take medicine, or wait. After strengthening publicity and educational activities regarding stroke, there was a significant improvement in the identification of stroke risk factors, warning signs, and stroke management. The percentage of participants who chose to make an emergency call increased from 53.2 to 82.7%. CONCLUSIONS: The knowledge about stroke among community residents in Jinjiang District of Chengdu was low. Strengthening publicity and educational activities may raise awareness about stroke prioritizing call emergency after the onset of stroke signs.

BACKGROUND: Infections could increase the risk of poor outcome in patients with acute ischemic stroke (AIS). The peripheral neutrophil-to-lymphocyte ratio (NLR) is an important indicator of inflammation. The purpose of our study was to investigate the association increased NLR with post stroke infections (PSI) in AIS. METHODS: In this study, we included 606 consecutive patients with AIS within 24 h. The NLR was calculated by dividing absolute neutrophil counts by absolute lymphocyte counts. Receiver operating characteristic (ROC) curve was performed to identify the optimal cut point of NLR for PSI. The relationship between NLR and PSI was analyzed by multivariable analysis. RESULTS: We assessed 606 consecutive patients with AIS. ROC curve analysis showed that the optimal cut point of NLR for PSI was NLR ≥ 5.79. Compared with no PSI, patients with PSI have higher NLR, older age, higher NIHSS, higher PCT, higher percentage of nasogastric tube feeding and indwelling urinary catheter (P < 0.05). Multivariable analysis showed that NLR ≥ 5.79 [adjusted odds ratio (aOR),4.52; 95% confidence interval (CI),3.02-6.76; P < 0.001], older age (aOR,1.03; 95% CI, 1.00-1.05; P = 0.009), higher admission NIHSS (aOR,1.13; 95%CI, 1.07-1.18; P < 0.001), indwelling urinary catheter (aOR1.83; 95%CI, 1.08-3.10; P = 0.026], and nasogastric tube feeding (aOR2.52; 95%CI, 1.38-4.59; P = 0.003) were associated with increased risk of PSI. CONCLUSIONS: Higher NLR can predict PSI in AIS patients. The NLR may help to select high-risk patients to start intervention in time.

BACKGROUND: Poststroke depression can lead to functional dependence, cognitive impairment and reduced quality of life. The aim of this study was to evaluate the effects of a percutaneous mastoid electrical stimulator (PMES) plus antidepressants on poststroke depression and cognitive function. METHODS: This study was a prospective, randomized, double-blind, and sham-controlled study. A total of 258 clinically depressed ischaemic stroke patients within 14 days of index stroke were randomly assigned to the PMES plus antidepressant (PMES group, N = 125) and sham plus antidepressant (sham group, N = 133) groups. All patients underwent the Montreal Cognitive Assessment (MoCA) and Hamilton Rating Scale for Depression (HRSD) test at 2 weeks (baseline), and 6 months(M6) after ischaemic stroke. Primary outcomes were the percentage of patients showing a treatment response (≥50% reduction in HRSD score) and depression remission (HRSD score ≤ 9) at 6 months. The secondary outcome was the percentage of patients with a MoCA score < 26. RESULTS: The percentages of patients showing a treatment response and depression remission were significantly higher in the PMES group than in the sham group (57.60% vs 41.35%, P = 0.009; 44.00% vs 29.32%, P = 0.014 respectively). The mean value of the HRSD score change [M (month)6-baseline] was significantly higher in the PMES group than in the sham group at 6 months (- 11.93 ± 5.32 vs - 10.48 ± 6.10, P = 0.036, respectively). The percentage of patients with MoCA scores < 26 was lower in the PEMS group than in the sham group (12.0% vs 24.06%, P = 0.012,respectively), and the mean value of the MoCA score change (M6-baseline) was higher in the PMES group than in the sham group (3.50 ± 2.55 vs 2.72 ± 2.52, P = 0.005, respectively). CONCLUSION: These findings demonstrate that PMES adjunctive to antidepressant therapy is effective in reducing depression, achieving remission in the short term, and improving cognition. TRIAL REGISTRATION: This trial was retrospectively registered (registration number: ChiCTR1800016463) on 03 June 2018.

INTRODUCTION: This prospective, randomized, multicenter head-to-head outcome study was performed to compare the efficacy and safety of Percutaneous Mastoid Electrical Stimulator (PMES) and Supraorbital Transcutaneous Stimulator (STS) in migraine prevention. METHODS: This was a prospective, randomized, head-to-head outcome study that involved three medical centers. After a one-month run-in, episodic patients with at least two migraine attacks/month were randomized to receive PMES daily for 45 min or STS daily for 20 min for three months. The primary outcomes were change in monthly migraine days and the 50% response rate. RESULTS: A total of 90 patients were included in this study. We observed statistically significant reduction of migraine days in the third month treatment both in the PMES group and STS group. The difference between the two groups was not significant (60.5% vs. 53.8%, p = 0.88). Of note, 77.8% patients in the PMES group and 62.2% patients in the STS group had a ≥50% reduction of migraine days in the third month (p = 0.070). The change in monthly migraine days, monthly migraine attacks, severity of migraine days, accompanying symptoms during migraine and monthly acute anti-migraine drug intake were not significantly different between the two groups. The change of Headache Impact Test-6 (HIT-6) from run-in to the third-month treatment in the STS group was more remarkable than that in the PMES group (36.5% vs. 25.6%, p = 0.041). The occurrence of discomfort paresthesia was higher in the STS group (13.3% vs. 0%, p = 0.026). CONCLUSION: PMES and STS treatment were both effective in migraine prevention. The safety and efficacy of PMES and STS were comparable.

BACKGROUND: Endothelial progenitor cells (EPCs) play an important role in ischemic stroke. However, there are few studies on the relationship between EPC and nondisabling ischemic cerebrovascular events. Our aim was to investigate the association of EPCs and SDF-1 (serum stromal cell-derived factor-1) with NICE (nondisabling ischemic cerebrovascular events). METHODS: TIA (transient ischemic attack) and minor stroke patients (153 in total) who had an onset of symptoms within 1 day were consecutively collected. 83 of the patients were categorized into the HR-NICE (high-risk nondisabling ischemic cerebrovascular event) group, and 70 of the patients were in the NHR-NICE (non-high-risk nondisabling ischemic cerebrovascular events) group. Adopted FCM (flow cytometry) was used to measure EPCs, taking double-positive CD34/KDR as EPCs. ELISA was used to measure the concentrations of serum SDF-1 and VEGF (vascular endothelial growth factor). By the sequence of admission time, 15 patients were selected separately from the HR-NICE group and NHR-NICE group, and another 15 healthy volunteers were chosen as the NC (Normal Control) group. The MTT method was used to measure the proliferation of EPCs of peripheral blood in all groups, and the Boyden chamber was used to measure the migration of EPCs. RESULTS: Compared with the NHR-NICE group, the HR-NICE group was older and contained more patients with hypertension and diabetes. Triglyceride, total cholesterol, and low-density lipoprotein in the HR-NICE group were also higher. For factors such as smoking, BMI (body mass index), and HCY (homocysteine), there were no significant differences (P > 0.05). Circulating EPCs, SDF-1, and VEGF in the NHR-NICE group were all higher. According to the multifactor regression analysis, age, hypertension, diabetes, total cholesterol, EPCs, and SDF-1 are independent risk factors for HR-NICE. For EPCs of 48-h isolated cultures, proliferation and migration were observed to be weakened compared with those of the NC group (P < 0.05). EPCs in HR-NICE group had lower proliferation and migration than those in NHR-NICE group (P < 0.01). CONCLUSIONS: For TIA and minor stroke patients, circulating EPCs and serum SDF-1 concentrations can be used to prognose HR-NICE. Factors that lead to high-risk NICE might be relevant to the decrease in proliferation and migration of circulating EPCs.

BACKGROUND: Capsular warning syndrome (CWS) is a rare clinical syndrome, which is defined as a recurrent transient lacunar syndrome. The mechanism and clinical management of CWS remain unclear. The aim of the study was to discuss the clinical characteristics of CWS and evaluate the different outcome between rt-PA and no rt-PA therapy. METHODS: The present multicenter retrospective study involved three medical centers, and the clinical data were collected from patients with CWS between January 2013 and December 2018. The clinical characteristics of CWS were analyzed. Patients were divided into two groups: rt-PA and no rt-PA groups. The therapeutic effects and prognosis of these two groups were analyzed. A good prognosis was defined as 3-month modified Rankin Scale (mRS) ≤ 2. RESULTS: Our study included 72 patients, 27 patients were assigned to rt-PA group, 45 in no rt-PA group. Hypertension and dyslipidemia were the most common risk factors. The mean number of episodes before irreversible neurological impairment or the symptoms completely disappeared was five times (range: 3-11 times). A total of 58 (80.55%) patients had acute infarction lesions on the diffusion weighted imaging (DWI). The most common infarct location was the internal capsule (41,70.69%), followed by the thalamus and pons. The difference in therapeutic effects between the rt-PA, single and double antiplatelet groups was not statistically significant (P > 0.05). A good prognosis was observed in 61 (84.72%) patients after 3 months, in which 23 (23/27, 85.19%) patients were from the rt-PA group and 38 (38/45,84.44%) patients were from the no rt-PA group (P > 0.05). After 3 months of follow-up, two patients had recurrent ischemic stroke. CONCLUSION: The most effective treatment of CWS remains unclear. Intravenous thrombolysis is safe for CWS patients. Regardless of the high frequency of infarction in CWS patients, more than 80% patients had a favorable functional prognosis.

BACKGROUND: Atrial fibrillation (AF) is a common cause of cerebral infarction, which could lead to endothelial dysfunction, increased reactive oxygen species (ROS) and oxidized low density lipoprotein (Ox-LDL).AF is associated with higher mortality and more severe neurologic disability. Statins may exert neuroprotective effects that are independent of LDL-C lowering. The purpose of our study was to investigate whether prestroke statins use could reduce plasma Ox-LDL levels and improve clinical outcomes in patients with AF-related acute ischemic stroke (AIS). METHODS: This was a multicenter prospective study that involved four medical centers, 242 AIS patients with AF were identified, who underwent a comprehensive clinical investigation and a 72 h-Holter electrocardiogram monitoring. All patients were divided into two groups: prestroke statins use and no prestroke statins use groups, who were followed up for 3 months. Plasma Ox-LDL levels were measured using enzyme-linked immunosorbent assay (ELISA) on admission and at 3 months. The outcome was death, major disability (modified Rankin Scale score ≥ 3), and composite outcome (death/major disability) at 3 months after AIS. RESULTS: One hundred thirty-six patients were in no prestroke statins use group, and 106 in prestroke statins use group. Plasma Ox-LDL levels were significantly lower in prestroke statins use than in no prestroke statins use on admission and at 3 months (P < 0.001). Plasma Ox-LDL levels on admission were associated with 3-month mortality [adjusted odds ratio (OR), 1.05; 95% confidence interval (CI), 0.99-1.12; P = 0.047]. In fully adjusted models, prestroke statins use was associated with reduced 3-month mortality [adjusted OR, 0.38; 95% CI, 0.16-0.91; P = 0.031)], major disability (adjusted OR, 0.38; 95% CI, 0.15-0.99; P = 0.047), and composite outcome (adjusted OR, 0.31; 95% CI, 0.17-0.74; P = 0.009). CONCLUSIONS: Prestroke statins use can reduce plasma Ox-LDL levels and improve clinical outcomes in patients with AF-related AIS.

BACKGROUND: Cardiac autonomic dysfunction caused by ischemic stroke might lead to an adverse outcome. Elevated high sensitivity cardiac troponin (hs-cTnT) is a marker of cardiac disease, it can elevate in acute stroke patients. The aim of the present study was to investigate association between serum hs-cTnT with prognosis among patients with acute ischemic stroke. METHODS: Five hundred and sixteen patients (mean age 66.19 ± 10.11) with acute ischemic stroke underwent a comprehensive clinical investigation and serum hs-cTnT activity test. All patients were followed up for 3 months. The prognosis was death or major disability (modified Rankin Scale score ≥ 3) at 3 months after acute ischemic stroke. RESULTS: 22.87% (118/516) of patients had serum hs-cTnT elevation (≥14 ng/l). Compared with normal hs-TnT group, the incidence of insular stroke (adjusted odds ratio, 2.84; 95% confidence interval, 1.48-4.17; P = 0.001) were more likely in patients with hs-cTnT elevation. In fully adjusted models, there was an association between serum hs-cTnT elevation and death (adjusted odds ratio, 3.14; 95% confidence interval, 1.16-8.49; P = 0.02) and major disability(adjusted odds ratio, 2.07; 95% confidence interval, 1.04-4.51; P = 0.04), and composite outcome(adjusted odds ratio,2.22;95% confidence interval,1.10-4.48; P = 0.03). CONCLUSIONS: Higher levels of serum hs-cTnT were independently associated with increased risk of death or major disability after stroke onset, suggesting that serum hs-cTnT may have prognostic value in poor outcomes of ischemic stroke.

RATIONALE: Transverse spinal cord infarction (SCI) is rare but highly disabling. Aortic thrombosis was described as one of the most common etiologies. Thromboembolic complications associated with intravenous immunoglobulin (IVIG) have been reported. PATIENT CONCERNS: A previously well, 64-year-old man who was given the treatment of IVIG (0.4 g/kg/d for 5 days) for exfoliative dermatitis 2 weeks before, progressively developed flaccid paraplegia of lower extremities, loss of all sensations below T3 level and urinary incontinence within 50 minutes. DIAGNOSES: A diagnosis of SCI and pulmonary embolism was made. IVIG was considered the possible cause. INTERVENTIONS: Anticoagulation treatment and continuous rehabilitation were administered. OUTCOMES: The neurologic deficiency of the patient was partially improved at the 3-year follow-up. LESSONS: The rapid development of severe deficits within 4 hours mostly contributes to the diagnosis of SCI. Heightened awareness of possible thrombotic events is encouraged for a month-long period following IVIG therapy.

OBJECTIVE: The purpose of this study was to investigate the predictive value of mean platelet volume (MPV) and platelet count (PC) in branch atheromatous disease (BAD). METHODS: This retrospective study included 216 patients with BAD-stroke within 48 h of symptom onset. These patients were divided into good and poor prognosis groups according to their 3-month modified Rankin scale scores after discharge. Multiple logistic regression analysis was used to evaluate independent predictors of poor prognosis in BAD-stroke patients. Receiver-operating characteristic (ROC) analysis was used to estimate the predictive value of MPV and PC on BAD-stroke. RESULTS: Our research showed that a higher MPV (aOR, 2.926; 95% CI, 2.040-4.196; p < .001) and PC (aOR, 1.013; 95% CI, 1.005-1.020; p = .001) were independently associated with poor prognosis after adjustment for confounders. The ROC analysis of MPV for predicting poor prognosis showed that the sensitivity and specificity were 74% and 84.9%, respectively, and that the AUC was .843 (95% CI, .776-.909, p < .001). The optimal cut-off value was 12.35. The incidence of early neurological deterioration (END) was 24.5% (53 of 163), and 66% of patients in the poor prognosis group had END (33 of 50). Multiple logistic regression analyses showed that elevated MPV and PC were associated with the occurrence of END (p < .05). CONCLUSION: Our results suggested that an elevated MPV and PC may be important in predicting a worse outcome in BAD-stroke patients. Our study also demonstrated an independent association of MPV and PC with END, which is presumably the main reason for the poor prognosis.

Esophageal squamous cell carcinoma (ESCC) is a common malignant tumor of the digestive tract. The most effective method of reducing the disease burden in areas with a high incidence of esophageal cancer is to prevent the disease from developing into invasive cancer through screening. Endoscopic screening is key for the early diagnosis and treatment of ESCC. However, due to the uneven professional level of endoscopists, there are still many missed cases because of failure to recognize lesions. In recent years, along with remarkable progress in medical imaging and video evaluation technology based on deep machine learning, the development of artificial intelligence (AI) is expected to provide new auxiliary methods of endoscopic diagnosis and the treatment of early ESCC. The convolution neural network (CNN) in the deep learning model extracts the key features of the input image data using continuous convolution layers and then classifies images through full-layer connections. The CNN is widely used in medical image classification, and greatly improves the accuracy of endoscopic image classification. This review focuses on the AI-assisted diagnosis of early ESCC and prediction of early ESCC invasion depth under multiple imaging modalities. The excellent image recognition ability of AI is suitable for the detection and diagnosis of ESCC and can reduce missed diagnoses and help endoscopists better complete endoscopic examinations. However, the selective bias used in the training dataset of the AI system affects its general utility.
