ABSTRACT

ObjectiveTo study the association of serum adiponectin and high sensitivity C-reactive protein (hs-CRP) levels to short-term outcome in patients with acute ischemic stroke (AIS). MethodsClinical data of 216 patients with AIS in Beijing Bo'ai Hospital from January, 2019 to September, 2020 were collected. The serum biochemical indicator was measured in all the patients within 24 hours after enrollment, and adiponectin was detected with enzyme-linked immunosorbent assay. Meanwhile, all patients were evaluated with National Institute of Health Stroke Scale (NIHSS). Modified Rankin Scale (mRS) was used to assess the functional outcome 90 days after onset during follow-up. ResultsThe incidence of poor outcome in patients with AIS within 90 days was 48.1%. Compared with the good outcome group, the serum adiponectin was lower (t = 5.861, P < 0.001) and the serum hs-CRP level was higher (Z = 5.525, P < 0.001) poor outcome group. Reduced serum adiponectin (OR = 0.862, 95%CI 0.751 to 0.975, P < 0.001) and increased serum hs-CRP (OR = 1.215, 95%CI 1.015 to 1.455, P < 0.001) were independent risk factors for poor outcome in patients with AIS. The areas under curve (95% CI) of serum adiponectin and hs-CRP for predicting the outcome of patients with AIS were 0.819 (0.761 to 0.877) and 0.722 (0.654 to 0.791), respectively (P < 0.001). The predictive power of serum adiponectin was higher than that of hs-CRP (Z = 2.151, P = 0.032). The optimum cut-off point of adiponectin was < 3.5 mg/L, and the Yoden index was 0.609, yielding a sensitivity of 0.704 and a specificity of 0.905. ConclusionSerum adiponectin and hs-CRP can serve as independent predictors for short functional outcome in patients with AIS.

ABSTRACT

ObjectiveTo investigate the association between serum 25-hydroxy vitamin D [25(OH)D] and the occurrence and outcome of stroke-associated pneumonia (SAP) in patients with acute ischemic stroke (AIS) in emergency ward. MethodsThe clinical data of 256 patients with AIS from January, 2019 to December, 2021 were collected in the emergency department of Beijing Bo'ai Hospital. Blood routine, biochemical indicators and serum concentration of 25(OH)D were detected within 24 hours after enrollment; meanwhile, National Institute of Health Stroke Scale (NIHSS) and A2DS2 score were evaluated. The patients were divided into non-SAP group (n = 164) and SAP group (n = 92) according to whether pneumonia occurred during hospitalization. Multivariable logistic regression model was used to analyze the influencing factors of SAP. The predictive ability of serum 25(OH)D and A2DS2 for SAP were evaluated by receiver operating characteristic (ROC) curves. The 28-day survival of patients with SAP was followed up. Multivariable Cox proportional hazard regression model was used to investigate the association between vitamin D nutritional status and 28-day all-cause mortality. ResultsSerum 25(OH)D was significantly lower in the SAP group than that in the non-SAP group (Z = 6.896, P < 0.001). After adjusting age, sex, infarct volume, A2DS2 score and other factors, lower serum 25(OH)D level (OR = 0.934, 95%CI 0.884 to 0.986, P = 0.014) was an independent risk factor for SAP. The areas under curve (95%CI) of serum 25(OH)D, A2DS2 score and their combined model for predicting SAP were 0.774 (0.718 to 0.824), 0.832 (0.781 to 0.876) and 0.851 (0.802 to 0.893) (P < 0.001), respectively; and the optimum cut-off values were 25(OH)D < 10.2 ng/mL, A2DS2 score > 5 points, combined prediction > 0.207, and the Youden index were 0.493, 0.662 and 0.616, respectively. A2DS2 score could improve the prediction efficiency of serum 25(OH)D (Z = 2.106, P = 0.035). After adjusting age, sex, infarct volume and NIHSS score, vitamin D deficiency was an independent risk factor for all-cause mortality after 28 days of SAP (HR = 2.871, 95%CI 1.004 to 8.208, P = 0.049) . ConclusionSerum 25(OH)D is independently associated with the occurrence and outcome of SAP in patients with AIS in emergency ward, which could serve as an independent predictor for SAP.

ABSTRACT

Objective:To establish a prediction model for major adverse cardiovascular and cerebrovascular events (MACCE) in elderly patients with emergency acute coronary syndrome (ACS) within 1 year, and to evaluate its prediction efficiency.Methods:This was a prospective cohort study. Elderly ACS patients who were admitted to the Cardiovascular Care Unit (CCU) or the Emergency Intensive Care Unit (EICU) in Beijing Bo'Ai Hospital through emergency department from January 2019 to December 2021 were successively enrolled. General data of the patients were collected within 24 h after admission, the incidence of malignant arrhythmia, complete revascularization and acute kidney injury (AKI) during hospitalization were recorded. Within 24 h, laboratory indexes such as serum creatinine (Scr), albumin (Alb), hypersensitive C-reactive protein (hs-CRP), creatine kinase isoenzyme MB (CK-MB), D-dimer, cardiac troponin I (cTnI) and N-terminal pro-brain natriuretic peptide (NT-pro-BNP) were measured. In addition, transthoracic echocardiography and the Frailty Screening Questionnaire (FSQ) were performed. Patients were followed up for the occurrence of MACCE within 1 year. The influencing factors of MACCE were screened by univariable and multivariable logistic regression analysis. The cut-off values of continuous variables were determined by receiver operating characteristic (ROC) curve and discretization was carried out with reference to clinical practice. Corresponding scores were set up according to the β regression coefficient of each variable to establish a clinical prediction score scale of MACCE. Finally, ROC curve was used to evaluate its prediction efficiency.Results:The study enrolled 322 elderly ACS patients, and the incidence of MACCE within 1 year was 24.5%. After preliminary screening of independent variables by univariable logistic regression analysis, the influencing factors of MACCE ( P<0.2) were as follows: ① Continuous indicators: age, body mass index (BMI), Alb, hs-CRP, D-dimer, NT-pro-BNP, ejection fraction (EF), Killip grade and FSQ score; ② Discrete indicators: ≥3 comorbidities, incomplete revascularization, and AKI. Multivariable logistic regression analysis after discretization of continuous indicators showed that age ≥84 years old [odds ratio ( OR)=4.351, 95% confidence interval (95% CI): 1.635-11.576, P=0.003], incomplete revascularization ( OR=6.580, 95% CI: 2.397-18.060, P < 0.001), combined with AKI ( OR=2.647, 95% CI: 1.085-6.457, P=0.032), EF ≤50% ( OR=2.742, 95% CI: 1.062-7.084, P=0.037), and FSQ≥3 points ( OR=9.345, 95% CI: 3.156-27.671, P < 0.001) were independent risk factors for MACCE. The total score of the clinical prediction system for MACCE was 8 points, including age ≥84 years old (2 points), incomplete revascularization (2 points), FSQ ≥3 points (2 points), EF ≤50% (1 point), and combined with AKI (1 point). The area under ROC curve (AUC) of the scoring system for predicting MACCE was 0.891, (95% CI: 0.844-0.938, P < 0.001). The optimal cut-off value was >3 points, and the sensitivity and specificity were 0.825 and 0.792, respectively. Conclusions:The prediction score scale of MACCE has a good diagnostic efficacy and has certain guiding value for clinicians to judge the prognosis of elderly ACS patients.

ABSTRACT

Objective:To explore the predictive value and prognosis effect of calprotectin on acute kidney injury (AKI) in patients with sepsis.Methods:A prospective observational study was conducted. From December 2018 to November 2020, patients with sepsis admitted to the Emergency Department of China Rehabilitation Research Center were enrolled. General clinical data of patients were collected continuously, and the acute physiology and chronic health evaluationⅡ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score and calprotectin were evaluated in 24 h after admission. The patients were divided into the AKI group and non-AKI group according to the occurrence of AKI within 7 days after admission. Calprotectin level and other clinical data were compared between the two groups. Logistic regression was used to analyze the risk factors for AKI in patients with sepsis, and receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of calprotectin for AKI in patients with sepsis. The patients with AKI were further divided into the survival group and death group according to the 28-day outcome, and the calprotectin levels between the two groups were compared.Results:A total of 207 patients with sepsis were enrolled, and the incidence of AKI was 68.12% (141/207). The level of calprotectin in patients with AKI was higher than that in patients without AKI [4.65 (3.25, 5.61) μg/mL vs. 3.42 (2.29, 4.09) μg/mL, P < 0.001]. Multivariable Logistic regression analysis showed that APACHEⅡ score ( OR=1.090, 95% CI: 1.043-1.139), C-reactive protein ( OR=1.004, 95% CI: 1.001-1.008) and calprotectin ( OR=1.590, 95% CI: 1.269-1.991) were independent risk factors for AKI in patients with sepsis. The area under ROC curve (AUC) of calprotectin for predicting AKI was 0.716 (95% CI: 0.643-0.788). The cutoff value of prediction was 4.63 μg/mL with the Yoden index of 0.405, which yielded a sensitivity of 0.511 and a specificity of 0.894. When calprotectin was combined with APACHE II score and SOFA score respectively, the predictive ability was significantly improved with the AUC of 0.768 (95% CI: 0.701-0.834) and 0.769 (95% CI: 0.701-0.837), respectively. We further divided patients with AKI into the survival group and non-survival group according to the 28-day outcome and there was no significant difference in calprotectin between the two groups [4.80 (3.40, 5.76) μg/mL vs. 4.19 (2.89, 5.29) μg/mL, P < 0.05]. Conclusions:The level of calprotectin in the AKI group is higher than that in the non-AKI group. Calprotectin can be regarded as an effective predictor of AKI in patients with sepsis, and the combination with APACHEⅡ score or SOFA score will improve its predictive efficacy. However, there is no significant difference in the concentration of calprotectin for patients with sepsis associated AKI with different prognosis.

ABSTRACT

Objective:To investigate the predictive value of mid-regional proadrenomedullin (MR-proADM) on poor prognosis of low-risk patients with sepsis.Methods:This was a prospective cohort study. Patients with sepsis admitted to the Emergency Intensive Care Unit of China Rehabilitation Research Center from December 2018 to December 2020 were included in this study. The patients were divided into the low-risk group (SOFA≤7) and medium-high-risk group (SOFA>7) according to the sequential organ failure assessment (SOFA) score, and the clinical characteristics of the two groups were compared. Proportional hazards regression model (COX regression model) was used to investigate the risk factors of 28-day mortality in the low-risk and medium-high-risk group. The predictive ability of MR-proADM, C-reactive protein (CRP), lactic acid (Lac), interleukin-6 (IL-6), SOFA score, and acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) score for the prognosis in each group was evaluated by receiver operating characteristic (ROC) curve. The outcomes of patients with different concentration of MR-proADM in the low-risk group were compared.Results:Totally 205 patients with sepsis were included, and the 28-day mortality was 41.0% (84/205). There were significant differences in the number of organ dysfunction, acute kidney injury, use of vasoactive drugs, Lac, IL-6, SOFA score and APACHEⅡ score between the two groups ( P<0.05). Cox regression model showed that age, MR-proADM, mechanical ventilation, IL-6 and APACHEⅡ score were the risk factors of 28-day death in the low-risk group, while MR-proADM, Lac, SOFA score and APACHEⅡ score were the risk factors of 28-day mortality in the medium-high-risk group. In each group, MR-proADM had a good predictive ability for the prognosis of patients with sepsis ( P<0.001). Especially in low-risk patients with sepsis, the predictive ability of MR-proADM was better than other indicators. Kaplan-Meier survival curve suggested that the patients with MR-proADM >2.53 nmol/L had worse prognosis than those with MR-proADM ≤2.53 nmol/L, and the difference was statistically significant ( P<0.001). In the low-risk group, the mortality of patients increased from 7.8% to 58.2% if MR-proADM >2.53 nmol/L. Conclusions:MR-proADM is a risk factor for 28-day mortality in patients with sepsis, and MR-proADM can early identify the poor prognosis of low-risk patients with sepsis.

ABSTRACT

Objective:To investigate the clinical value of nutritional indexes including body mass index (BMI), albumin (ALB), nutrition risk screening 2002 (NRS 2002) and the nutrition risk in critically ill score (NUTRIC) in 28-day prognosis of patients with sepsis related acute kidney injury (AKI).Methods:A prospective cohort study was conducted. Patients with sepsis treated in the emergency intensive care unit (EICU) of China Rehabilitation Research Center from December 1, 2018 to December 1, 2020 were observed for 7 days. Patients with sepsis related AKI were enrolled in this study. The gender, age, BMI, basic diseases, shock, number of affected organs, length of hospital stay, ALB, mechanical ventilation (MV) and vasoactive drug use, sequential organ failure score (SOFA), rapid sequential organ failure score (qSOFA) and acute physiology and chronic health evaluationⅡ(APACHEⅡ) were recorded. The NRS 2002 score and NUTRIC score were calculated. Cox regression model was used to analyze the risk factors of 28-day mortality in patients with sepsis related AKI. The receiver operator characteristic curves (ROC curves) were drawn and the areas under the ROC curves (AUC) were calculated, and the value of BMI, ALB, NRS 2002 score and NUTRIC score was analyzed to predict 28-day mortality in patients with sepsis related AKI. Kaplan Meier survival curves were used to analyze the effects of NRS 2002 score and NUTRIC score stratification on the 28 day prognosis of patients with sepsis related AKI.Results:A total of 140 patients with sepsis related AKI were enrolled, including 73 survival patients and 67 died patients within 28 days. The 28-day mortality was 47.9% (67/140). BMI in the survival group was significantly higher than that in the death group [kg/m 2: 22.0 (19.5, 25.6) vs. 20.7 (17.3, 23.9), P < 0.05], and NRS 2002 score and NUTRIC score were significantly lower than those in the death group [NRS 2002 score: 5 (4, 6) vs. 7 (6, 7), NUTRIC score: 6 (5, 7) vs. 7 (6, 9), both P < 0.05]. The ALB of the survival group was slightly higher than that of the death group, but the difference was not statistically significant. Cox regression analysis showed that NRS 2002 score and NUTRIC score were independent risk factors for 28-day death in patients with sepsis related AKI. ROC curve analysis showed that NUTRIC score had the strongest predictive ability for 28-day death [AUC = 0.785, 95% confidence interval (95% CI) was 0.708-0.850], followed by NRS 2002 score (AUC = 0.728, 95% CI was 0.647-0.800), but there was no significant difference between them. Compared with NRS 2002 score, the predictive ability of BMI and ALB was poor. Kaplan-Meier curve analysis showed that the prognosis of patients with NRS 2002 score≥5 was significantly worse than that of patients with NRS 2002 score < 5 (28-day cumulative survival rate: 42.1% vs. 75.6%, Log-Rank test: 2 = 11.884, P = 0.001), and the prognosis of patients with NUTRIC score≥6 was significantly worse than that of patients with NUTRIC score < 6 (28-day cumulative survival rate: 40.4% vs. 86.1%, Log-Rank test: 2 = 19.026, P = 0.000). Conclusions:Patients with sepsis related AKI have high nutritional risk. Both NRS 2002 score and NUTRIC score have good predictive value for the prognosis of patients with sepsis related AKI, while BMI and ALB have low predictive value. Due to the complex calculation of NUTRIC score, NRS 2002 score may be more suitable for emergency department.

ABSTRACT

Objective:To observe the changes of serum histone H4 level and its predictive value in patients with septic cardiomyopathy.Methods:A prospective study was conducted. A total of 147 patients with sepsis and septic shock were collected in emergency department. The general data were recorded. Transthoracic echocardiography and plasma histone H4 were conducted within 24 hours and 7 days after admission.The scores of sequential organ failure assessment(SOFA), acute physiology and chronic health evaluationⅡ(APACHEⅡ), and nutritional risk screening 2002 (NRS2002) were evaluated within 24 hours. According to whether septic cardiomyopathy occurred, the patients were divided into two groups, and dynamic changes of histone H4 on the first and seventh day of the two groups were observed. The factors influencing the occurrence of septic cardiomyopathy were analyzed by multivariate logistic regression. The prediction ability of serum histone H4 on septic cardiomyopathy was evaluated by receiver operating curve (ROC).Results:The incidence of septic cardiomyopathy was 28.6% (42 / 147). The level of histone H4 in septic cardiomyopathy group was higher than that in non septic cardiomyopathy group ( Z = 4.449, P < 0.001), and dynamic detection showed that the level of histone H4 on the seventh day was lower than that on admission ( Z=3.057, P=0.002). Multivariate logistic regression showed that the high serum histone H4 level [Odd Ratio( OR)=1.337, 95% confidence interval (95% CI) was 1.173-1.522, P < 0.001], SOFA ( OR= 1.474, 95% CI 1.227-1.769, P < 0.001), older age ( OR = 1.074, 95% CI 1.019-1.132, P = 0.008) were independent risk factors for septic cardiomyopathy. The area of ROC curve for serum histone H4 to predict septic cardiomyopathy was 0.729 ( P < 0.001), the predictive cut-off value was 10.81 ng/ml, which yielded a sensitivity 0.524 and a specificity of 0.914. Conclusions:The level of histone H4 showed dynamic change in septic cardiomyopathy, and high serum histone H4 level has a good predictive value for the occurrence of septic cardiomyopathy.

ABSTRACT

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.

ABSTRACT

Objective:This paper constructs a generalized regression neural network (GRNN) model to predict the disintegration time of traditional Chinese medicine (TCM) tablets. Method:Taking Astragali Radix as a model drug, the mixed Astragali Radix powders with different powder properties were prepared by mixing Astragali Radix extract powders with microcrystalline cellulose and lactose, which were made to Astragali Radix tablets by direct compression method. The powder properties of mixed Astragali Radix powders and the disintegration time of Astragali Radix tablets were determined, respectively. The correlation between the original data was eliminated by principal component analysis (PCA). The principal component factors were used as the input layer of the GRNN model, and the disintegration time was used as the output layer for network training. Finally, the verification group data was used to predict the disintegration time, and the network prediction accuracy was calculated by comparing with the actual value. Result:Three principal component factors were obtained through PCA by analyzing the original nine variables that were correlated with each other (Hausner ratio, true density, tap density, compression degree, angle of repose, bulk density, porosity, water content and total dissolved solids), which reduced the complexity of the network. The prediction value of the disintegration time based on this prediction method was in good agreement with the actual value, the error of disintegration time was 0.01-1.34 min and the average relative error was 3.16%. Conclusion:Based on the GRNN mathematical model, the physical properties of Astragali Radix extract powders can be used to accurately predict the disintegration time of Astragali Radix tablets, which provides a reference for studying the disintegration time of TCM tablets.

ABSTRACT

Objective:To establish a clinical diagnostic scoring system for septic cardiomyopathy (SCM) and evaluate its diagnostic efficacy.Methods:A prospective cohort study was performed. Patients with sepsis and septic shock admitted to the department of emergency of China Rehabilitation Research Center were enrolled from January 2019 to December 2020. The baseline information, medical history, heart rate (HR), mean arterial pressure (MAP), body temperature and respiratory rate (RR) on admission were recorded. Laboratory indexes such as white blood cell count (WBC), hypersensitivity C-reactive protein (hs-CRP), N-terminal pro-brain natriuretic peptide (NT-proBNP), and blood lactic acid (Lac) were measured. Transthoracic echocardiography was conducted within 24 hours and on the 7th after admission. Sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluationⅡ(APACHEⅡ), and nutritional risk screening 2002 scale (NRS2002) were also assessed. The patients were divided into two groups according to whether SCM occurred or not. The risk factors of SCM were screened by univariate and multivariate Logistic regression. The cut-off value of continuous index was determined by receiver operator characteristic curve (ROC curve) and discretized concerning clinical data. The regression coefficient β was used to establish the corresponding score, and the clinical diagnostic score system of SCM was established. The diagnostic value of the model was evaluated by ROC curve.Results:In total, 147 patients were enrolled in the study and the incidence of SCM was 28.6% (42/147). Univariate Logistic regression analysis showed the risk factors of SCM included: ① continuous indicators: age, NT-proBNP, RR, MAP, Lac, NRS2002, SOFA, APACHEⅡ; ② discrete indicators: shock, use of vasoactive drugs, history of coronary heart disease, acute kidney injury (AKI). Multivariate Logistic regression analysis after discretization of above continuous index showed that age≥87 years old, NT-proBNP≥3 000 ng/L, RR≥30 times/min, Lac≥3 mmol/L and SOFA≥10 points were independent risk factors for SCM [age ≥87 years: odds ratio ( OR) = 3.491, 95% confidence interval (95% CI) was 1.371-8.893, P = 0.009; NT-proBNP≥3 000 ng/L: OR = 2.708, 95% CI was 1.093-6.711, P = 0.031; RR≥30 times/min: OR = 3.404, 95% CI was 1.356-8.541, P = 0.009; Lac≥3 mmol/L: OR = 3.572, 95% CI was 1.460-8.739, P = 0.005; SOFA≥10 points: OR = 8.693, 95% CI was 2.541-29.742, P = 0.001]. The clinical diagnostic score system of SCM was established successfully, which was composed of age≥87 years old (1 point), NT-proBNP ≥ 3 000 ng/L(1 point), RR≥30 times/min (1 point), Lac≥3.0 mmol/L (1 point), SOFA≥10 points (2 points), and the total score was 6 points.

ABSTRACT

Objective:To explore the change of serum 25-hydroxyvitamin D [25(OH)D] and prediction for outcome of acute ischemic stroke in emergency. Methods:From October, 2017 to September, 2019, 224 patients with acute ischemic stroke in emergency and 240 healthy controls were detected serum 25(OH)D within 24 hours after enrollment. The patients were assessed with National Institute of Health Stroke Scale (NIHSS) and Nutritional Risk Screening 2002 (NRS2002), and measured biochemics within 24 hours after admission. They were assessed with modified Rankin Scale (mRS) 180 days after stroke, and divided into favourable group (mRS ≤ 2, n = 106) and unfavourable group (mRS > 2, n = 118). The factors related with the outcome were analyzed with Logistic regression, and the prediction of 25(OH)D for the outcome were analyzed with receiver operator characteristic (ROC) curve. Results:Serum 25(OH)D was less in the patients than in the controls (Z = 4.296, P < 0.001), and less in the unfavourable group than in the favourable group (Z = 5.876, P < 0.001). Serum 25(OH)D (OR = 0.925, P < 0.05) was related with the outcome even controlling the impacts of age, sex, nutritional risk, infarct volume, scores of NIHSS, etc. The area under curve for serum 25(OH)D predicting outcome was 0.795 (P < 0.001). The cut-off point of prediction was 13.17 ng/ml, with the Yoden index of 0.548, which yielded a sensitivity of 0.746 and a specificity of 0.802. Conclusion:Serum 25-hydroxyvitamin D may predict the outcome 180 days after acute ischemic stroke, which may help for risk stratification in emergency.

ABSTRACT

Objective: To determine the expression of anoikis factor Bcl2 inhibitor of transcription 1 (Bit1), epithelial-mesenchymal transformation (EMT) marker E-cadherin and P16INK4a in tumor budding and central tumor of cervical squamous cell carcinoma, and to explore the significance of Bit1 and E-cadherin expression in the process of obtaining high invasiveness of cervical cancer and their relationship with P16INK4a expression. Methods: A total of 77 paraffin-embedded specimens of cervical squamous cell carcinoma were collected from the Department of Pathology of Gansu Provincial Cancer Hospital between 2014 and 2018. The expression levels of Bit1, E-cadherin and P16INK4a in tumor budding and central tumor of these specimens were detected by immunohistochemistry. Taking the median scores of protein expression in the central tumor and tumor budding as dividing points, the specimens were divided into high expression group and low expression group. The differences of Bit1 and E-cadherin expression under different p16INK4a expression and their relationship with the clinicopathological characteristics of the patients were analyzed. The correlation between Bit1 and E-cadherin expression in central tumor and tumor budding was explored. The χ2 test, continuous correction χ2 test and Spearman rank correlation analysis were used for statistical analysis. Results: In 77 cases of paraffin-embedded specimens of cervical squamous cell carcinoma, the high expression rates of P16INK4a, E-cadherin and Bit1 in central tumor and tumor budding were 32.5% (25/77), 67.5% (52/77) and 63.6% (49/77), and 67.5% (52/77), 33.8% (26/77) and 37.7% (29/77), respectively, and the differences were significant (χ2 18.935, 17.561 and 10.391, all P < 0.01). Both in central tumor and in tumor budding, there were no significant differences in Bit1 or E-cadherin expression between high and low P16INK4a expression regions (all P < 0.05). In central tumor, the low expression of Bit-1 was related to lymphovascular invasion and lymph node metastasis (χ2 5.053 and 4.400, both P < 0.05). In tumor budding, the low expression levels of E-cadherin and Bit-1 were both associated with lymph node metastasis (χ2 5.580 and 7.573, both P < 0.05). Spearman rank correlation analysis showed that there was positive correlation between E-cadherin and Bit1 expression in central tumor and tumor budding (r 0.287, P = 0.011; r 0.236, P < 0.039). Conclusion: The increased invasiveness of cervical cancer may be related to the decreased expression of Bit1 and E-cadherin and the increased expression of P16INK4a. Cervical cancer cells may acquire high invasiveness by inhibiting Bit1 to obtain anoikis resistance and affecting the EMT, but P16INK4a is not involved in this process.

ABSTRACT

Objective:To explore the characteristics of nosocomial infection in patients with spinal cord injury, and analyze the risk factors. Methods:From January, 2015 to June, 2017, 526 patients with spinal cord injury in our hospital were reviewed. The distribution of pathogens and the characteristics of drug resistance of strains were summarized, and the risk factors of nosocomial infection were analyzed. Results:There were 159 person-times with nosocomial infection, and most of the infections were found in urinary tract (60.4%) and lower in respiratory tract (28.9%). The main pathogenic germs were Escherichia coli (39.0%), Pseudomonas aeruginosa (15.7%), Klebsiella pneumoniae (11.3%) and Proteus mirabilis (9.4%). The main pathogens were resistant to second or third generation of cephalosporins and quinolones moderately or severely, but sensitive to compound preparations containing beta-lactamase inhibitors, carbapenems and aminoglycosides. The risk factors for the nosocomial infections in the spinal cord injury patients included the hospitalization time, severity of spinal cord injury, invasive operation history, nutritional risk and use of antibiotics (P < 0.05). Conclusion:Most of the nosocomial infections in patients with spinal cord injury are in urinary tract and respiratory tract. Gram-negative bacilli are the main pathogenic bacteria, which often show multiple drug resistance. It is necessary to take targeted interventions according to the risk factors of nosocomial infections in order to improve the quality of life of patients.

ABSTRACT

Objective:To investigate the compatible stability of Xingnaojing injection in combination with 9 common medicines, and to provide a reference for clinical application of this injection. Method:According to the clinical application, Xingnaojing injection was mixed with 9 common medicines and placed in the room under dark and light conditions for 6 h. The appearance of compatible solutions was observed, and the HPLC fingerprint was analyzed by similarity evaluation and principal component analysis(PCA). Result:There were no significant changes in the appearance of compatibility of Xingnaojing injection and 9 common medicines, including piracetam and sodium chloride injection, sodium chloride injection and others. The similarities of fingerprint among compatibility of Xingnaojing injection and 9 common medicines were >0.98 at 0 h of compatibility, 6 h of placement and 6 h of illumination. The results of PCA showed that 9 groups of compatible solutions were clustered into 2 categories, the compatibility of Xingnaojing injection and 8 groups including piracetam and sodium chloride injection clustered into one category, and the relative peak areas of the characteristic components of Xingnaojing injection did not change significantly after compatibility, the compatibility of Xingnaojing injection and Danshen Chuanxiongqin injection clustered into another category, the relative peak areas of some characteristic components of Xingnaojing injection increased after compatibility of 0 h and 6 h,and it was more obvious after 6 h of illumination. Conclusion:The compatibility of Xingnaojing injection and 8 common medicines including piracetam and sodium chloride injection has good stability, while the compatibility has stability problems after Xingnaojing injection mixed with Danshen Chuanxiongqin injection. It is suggested that clinical attention should be paid to their compatibility and rational combination of medicines.

ABSTRACT

Objective:To carry out the risk assessment on the factors in the process of granulation fluidized bed of traditional Chinese medicine(TCM) by using failure model and effect analysis(FMEA) and Bayesian network(BN), in order to effectively control risk factors and improve product quality. Method:The risk analysis of the fluidized bed granulation process was carried out by FMEA and the selected medium risk and high risk factors were taken as the main control points, the corresponding BN was established. The sensitivity analysis was used to screen out the main risk factors affecting particle fluidity, particle size uniformity, solubility and product cleanliness, the occurrence probability of each risk factor was determined by the evidence of unqualified particle quality, finally, taking fluidized bed granulation process of Sanye tablets as an example, the FMEA and BN were combined into the risk assessment process to verify the effectiveness and reliability of the method. Result:Based on the middle and high risk points of fluidized bed process, particle size of raw materials, moisture content and hygroscopicity of raw materials, dosage, concentration and addition amount of binder, cleaning degree and integrity of collection bag, and nozzle position, which were selected by FMEA, a fluidized bed granulation risk network with causality was constructed. Among them, hygroscopicity of raw materials, concentration and addition amount of binder, inlet temperature and atomization pressure were high probability risk factors, and the probability of occurrence were 55%, 63%, 59%and 58%, respectively. According to the Bayesian risk relationship network which controlled Sanye tablets fluidized bed granulation analysis results showed that the P values of inlet temperature, atomization pressure and concentration of binder were 0.003 4, 0.032 6 and 0.041 8, respectively in the regression model of influencing factors and particle size uniformity, indicating that there was a significant correlation between the three factors and the particle quality, which was basically consistent with the conclusion obtained by FMEA-BN method. Conclusion:The combination of FMEA and BN for visualized risk assessment of fluidized bed granulation helps to effectively control the risk factors in the granulation process, reduce product quality risks and provide strong support for the improvement of granulation process of TCM.
