ObjectiveTo explore the early factors influencing 30 days survival of hypertensive intracerebral hemorrhage.MethodsThe data of 96 cases of hypertensive intracerebral hemorrhage were analyzed with log-rank and cox model.ResultsGCS scores, systolic blood pressure (SBP), diastolic blood pressure (DBP), body temperature, FPG, the volume of hemorrhage whether or not breaking through ventricle were significant factors in log-rank and GCS scores, body temperature, FPG, the volume of hemorrhage showed a significant relation in cox model.ConclusionMany factors can induce the death of hypertensive intracerebral hemorrhage patients; the most important factors are coma, body temperature, FPG, the volume of hemorrhage.

Objective To study the effect of cerebrovascular accident on lower urinary tract.Methods A retrospective review of non-complete synchronized videourodynamic recordings of 19 patients with cerebrovascular accident and 19 cases with thoracic spinal cord injury in synchronization was performed.Results The patients with cerebrovascular accident were found mainly detrusor hyperreflexia,low bladder compliance,sphincter relaxation,and the detrusor hyperreflexia was noted primarily in lesions of the basal ganglia lobe as well as the frontal.These characteristics were different from the cases with thoracic spinal cord injury.Conclusion The videourodynamic findings are mainly detrusor hyperreflexia and sphincter relaxation in patients with micturitional disturbance after cerebrovascular accident.It is different from findings in patients with thoracic spinal cord injury.

Objective:To investigate the correlation between the level of serum 25-hydroxyvitamin D [25(OH)D] and infarction volume in patients with acute ischemic stroke (AIS) with internal carotid artery system (anterior circulation).Methods:A prospective cohort study was conducted. Patients with AIS admitted to the department of emergency of Beijing Boai Hospital from October 2017 to September 2019 were enrolled. Nutritional risk screening 2002 (NRS 2002) were assessed in all cases within 24 hours after enrollment. Fasting venous blood was collected for biochemical analysis, including albumin (ALB), homocysteine (HCY), uric acid (UA), hypersensitive C-reactive protein (hs-CRP), etc. Serum 25(OH)D level was detected by electrochemiluminescence immunoassay. Magnetic resonance imaging (MRI) was performed to calculate the volume of cerebral infarction. According to the volume of cerebral infarction, the patients were divided into small volume (≤ 1 cm 3) group, medium volume (1 cm 3 < infarct volume < 20 cm 3) group and large volume (≥20 cm 3) group. The differences of serum 25(OH)D and other indicators in each group were compared; the influencing factors of infarct volume were analyzed by Logistic regression; and the goodness of fit of regression model was tested by Hosmer-Lemeshow (HL). Results:A total of 224 patients with AIS were enrolled, 92 in small volume group, 90 in medium volume group and 42 in large volume group, and there was no significant difference in serum 25(OH)D level among small, medium and large volume groups [μg/L: 13.21 (7.47, 19.33), 11.20 (7.00, 15.07), 9.19 (6.30, 17.10), H = 4.994, P = 0.082]. There were 124 patients with AIS in anterior circulation, 45, 56 and 23 patients in the small, medium and large volume groups, respectively, with the increase of the cerebral infarction volume, the serum 25(OH)D level in small, medium and large volume groups decreased gradually, and the difference was statistically significant [μg/L: 13.22 (9.00, 19.65), 10.41 (6.72, 14.92), 8.30 (4.70, 11.30), H = 11.068, P = 0.004]. In addition, with the increase of the cerebral infarction volume, the older the patients with AIS in anterior circulation [years old: 63.0 (54.0, 75.5), 76.0 (63.0, 84.0), 82.0 (67.5, 85.0), H = 14.981, P = 0.001], the higher the nutritional risk ratio (35.6%, 53.6%, 73.9%, χ2 = 9.271, P = 0.010), the higher the serum hs-CRP level [mg/L: 1.91 (0.92, 3.40), 4.10 (1.73, 22.42), 19.74 (4.02, 68.81), H = 21.477, P < 0.001], and the lower the ALB level (g/L: 42.30±12, 38.11±5.06, 35.14±5.49, F = 19.347, P < 0.001). After adjusting for age, gender, atrial fibrillation, nutritional risk, hs-CRP and other confounding factors, serum 25(OH)D was an independent protective factor for the infarct volume of AIS in anterior circulation [odds ratio ( OR) = 0.962, P = 0.040], For every 10 μg/L decrease of 25(OH)D, the risk of one grade increase in infarction volume was increased by 47.7% respectively (goodness of fit: χ2 = 5.357, P = 0.719). Conclusion:The low serum 25(OH)D level was associated with the increase of infarct volume in the anterior circulation cerebral infarction, and early detection of serum 25(OH)D level can help risk stratification of AIS patients.

ObjectiveTo explore the risk factors of stroke-associated pneumonia (SAP) for patients with mild to moderate acute ischemic stroke (AIS). MethodsFrom October, 2016 to December, 2019, 321 patients with mild to moderate AIS in Beijing Bo'ai Hospital were collected and divided into SAP group (n = 71) and non-SAP group (n = 250) according to whether they were complicated with SAP. Gender, age, time from symptom onset to admission, systolic pressure, diastolic pressure, scores of National Institutes of Health Stroke Scale (NIHSS) at admission, and medical history were recorded. Laboratory indexes including the count of white blood cell and platelet, levels of D-dimer, hypersensitive C-reactive protein (hs-CRP) and α-hydroxybutyrate dehydrogenase (α-HBDH) were measured. ResultsUnivariate analysis showed that age, NIHSS score, history of hypertension, atrial fibrillation, prior cerebral infarction, the count of white blood cell and platelet, the levels of D-dimer, hs-CRP and α-HBDH were the influencing factors of SAP (P < 0.2). Multivariate Logistic regression showed that age > 70 years old (OR = 7.121, 95%CI 3.493 to 14.514, P < 0.001), NIHSS score > 4 (5 to 10, OR = 4.861, 95% CI 2.412 to 9.797, P < 0.001), the count of platelet > 300×10⁹/L (OR = 6.978, 95% CI 1.864 to 26.128, P = 0.004), and the level of D-dimer > 1.0 mg/L (OR = 3.036, 95% CI, 1.518 to 6.071, P = 0.002) were the risk factors of SAP. The model fitted the original data well (HL = 1.509，P = 0.680) and appeared a good prediction (AUC = 0.847, 95% CI 0.796 to 0.898, P < 0.001). ConclusionAge > 70 years old, NIHSS score > 4 (5 to 10), the count of platelet > 300×10⁹/L and the level of D-dimer > 1.0 mg/L were the risk factors of SAP for patients with mild to moderate AIS.
