ABSTRACT
Objective:To investigate the correlation between strong ion gap (SIG) and prognosis of adult hospitalized patients who experienced cardiac arrest (CA).Methods:A retrospective cohort study was conducted on adult CA patients (≥18 years old) who were admitted to the intensive care unit (ICU) for the first time from the Medical Information Mart for Intensive Care Ⅲ (MIMIC-Ⅲ) database from 2001 to 2012. The patients were divided into 3 groups based on the tertiles of serum SIG value. The clinical baseline characteristics and related data of CA patients were compared. Kaplan-Meier method was used to draw the 28- and 90-day cumulative survival curves of CA patients. Meanwhile, the log-rank test was used to compare the differences in the survival curves among different groups, and Cox proportional hazard regression model was established to analyze whether SIG was an independent predictor of all-cause mortality in CA patients.Results:Six hundred and six adult CA patients were eligible for final analysis. The patients were divided into 3 groups based on the tertiles of serum SIG value [<3.91 mmol/L ( n=202), 3.91~7.32 mmol/L ( n=202) and >7.32 mmol/L ( n=202)]. The mean age was (66.91±15.95) years and 382 patients (63.04%) were male. The all-cause mortality rates of ICU, 28 days and 90 days were 36.47%, 49.17% and 56.93%, respectively. There were significant differences in SOFA score, SIG, anion gap, pH, lactic acid, white blood cells, prothrombin time, creatinine, blood potassium, blood phosphorus, hypertension, coronary heart disease, cardiogenic shock, and ICU, 28-day and 90-day all-cause mortality among the 3 groups (all P<0.05). The Kaplan-Meier survival curves showed that the 28- and 90-day cumulative survival rates of CA patients decreased gradually with the increase of SIG level, and the differences were statistically significant among the 3 groups (all P<0.001). Multivariate Cox proportional hazard models showed that the increase of SIG level (>7.32 mmol/L) was an independent risk factor for 28-day ( HR=1.610, 95% CI: 1.177-2.203, P=0.003) and 90-day all-cause mortality ( HR=1.506, 95% CI: 1.123-2.019, P=0.006) among CA patients, after adjusting for the related confounders. Conclusions:The elevated SIG level (>7.32 mmol/L) is an independent predictor of 28- and 90-day all-cause mortality in CA patients. The calculation of SIG level in these patients is helpful for early identification of patients with poor prognosis.
ABSTRACT
Electroencephalogram (EEG) is characterized by high temporal resolution, and various EEG analysis methods have developed rapidly in recent years. The EEG microstate analysis method can be used to study the changes of the brain in the millisecond scale, and can also present the distribution of EEG signals in the topological level, thus reflecting the discontinuous and nonlinear characteristics of the whole brain. After more than 30 years of enrichment and improvement, EEG microstate analysis has penetrated into many research fields related to brain science. In this paper, the basic principles of EEG microstate analysis methods are summarized, and the changes of characteristic parameters of microstates, the relationship between microstates and brain functional networks as well as the main advances in the application of microstate feature extraction and classification in brain diseases and brain cognition are systematically described, hoping to provide some references for researchers in this field.

Incision infection is one of the common complications in surgery. Infected incisions usually need to perform procedures including suture removal, debridement, drainage, sterilization and anti-inflammatory. Until, the wound edge was sutured again after the wound infection was controlled. This contributes to considerable physical and psychological suffering for patients. To this end, with Dalian Medical University as the main inventor and other several experts, a multi-assistance function incision and orifice closure buckle have been designed and obtained the national utility model patent (patent number: ZL 2019 2 1803918.4). The closure buckle with was composed of two blocks with an adhesive layer and one tensioning mechanism. The device is easy to operate, and could effectively play an analgesic, antibacterial and promote healing on the basis of perfecting its wound margins and orifice. It has certain clinical application value.
ABSTRACT
Objective:To investigate the association between the initial red cell distribution width (RDW) and all-cause mortality in patients with cardiac arrest (CA) in intensive care unit (ICU).Methods:We conducted a retrospective cohort study and extracted the related clinical data in ICU among adult CA patients (age ≥18 years), using the Multiparameter Intelligent Monitoring Intensive Care III (MIMIC-Ⅲ, v1.4) database from 2001 to 2012. Based on whether they survived or not on 90 days, the patients were divided into the survival group and death group, and the clinical data of the two groups were compared. Meanwhile, the RDW values were divided into four parts according to quartile. The cumulative survival rate of 28-day and 90-day were estimated using the Kaplan-Meier method and compared using the log-rank test. Multivariate Cox proportional hazard models were also used to reveal the association between RDW and all-cause mortality.Results:Based on the inclusion and exclusion criteria, 853 adult CA patients were finally enrolled. The mean age was (67.26±15.84) years, and 534 (62.60%) patients were male. And the mean SOFA score was (6.13±3.70). Compared with the survival group ( n=410), the patients in the death group ( n=443) were older and had a higher SOFA score, RDW, anion gap, creatinine and blood phosphorus. Moreover, the proportion of chronic obstructive pulmonary disease, acute kidney injury and sepsis in the death group were higher than those in the survival group, and the length of stay in ICU in the death group was longer than that in the survival group (all P<0.05). However, the indicators of arterial blood oxygen partial pressure, hemoglobin and total blood calcium, as well as the proportion of coronary heart disease and acute myocardial infarction were lower than those in the survival group, and a shorter duration of hospitalization in the death group was noted (all P<0.05). Kaplan-Meier survival curves demonstrated that there was a significant difference in the cumulative survival rate of 28-day and 90-day (all P<0.001). In the multivariate Cox proportional hazard models, a higher RDW at ICU admission was an independent risk factor for 28-day ( HR=1.399, 95% CI: 1.014-1.930, P=0.041) and 90-day ( HR=1.433, 95% CI: 1.064-1.929, P=0.018) all-cause mortality among CA patients. Conclusions:An elevated RDW is an independent predictor for 28-day and 90-day all-cause mortality of CA patients. As a clinical indicators, it indicates a poor prognosis for adult CA patients.
ABSTRACT
Objective:To establish the UPLC fingerprint analysis method for Puerariae Lobamle Radix. Methods:The column was Agilent ZORBAX Eclipse Plus C18 column (2.1 mm×100 mm, 1.8 μm). The mobile phase consisted of acetonitrile (A)-0.1% formic acid (b), gradient elution, flow rate was 0.3 ml/min. The detection wavelength was 250 nm. The column temperature was set at 30 ℃. The sample volume was 2 μl, and the similarity evaluation system of traditional Chinese medicine fingerprint was adopted. The cluster analysis, principal component analysis and partial least square method in SPSS software were used to judge the differences of Pueraria lobata from different habitats.Results:With puerarin as reference peak, 22 common peaks were calibrated, and 6 peaks were identified. The similarity of 25 batches of samples was above 0.990 except S22 was 0.935, which indicated that the samples were with good consistency. Through cluster analysis, principal component analysis and partial least square analysis, 25 batches of Puerariae Lobamle Radix can be clustered into 4-5 categories, and different components such as 3'-hydroxy puerarin were found. The extraction process of Puerariae Lobamle Radix was optimized based on analytic hierarchy process and multi-index orthogonal test. The results showed that adding 50% ethanol 40 ml and refluxing for 40 min was the best extraction process. Conclusion:UPLC fingerprint is suitable for Puerariae Lobamle Radix, and the results are reliable. It can be used as a quality evaluation method for Puerariae Lobamle Radix.
ABSTRACT
Objective:To investigate the role of peroxisome proliferator-activated receptor γ (PPARγ)/CD36 signaling pathway in macrophage lipid metabolism after Mycobacterium tuberculosis ( Mtb) infection. Methods:THP-1-derived macrophages were infected with Mtb. Four groups were included in this study, which were control group, Mtb infection group, Mtb+ rosiglitazone (ROZ, PPARγ agonist) group and Mtb+ GW9662 (PPARγ antagonist) group. Western blot and RT-PCR were used to detect the expression of PPARγ in macrophages at protein and mRNA levels, respectively. The lipids in cells were detected by oil red O staining. The concentrations of total cholesterol (TC), triglycerides (TG), low density lipoprotein (LDL-C) and high density lipoprotein (HDL-C) in the supernatant of cell culture were detected by automatic biochemical analyzer. The expression of CD36 was detected by immunohistochemistry. CCK-8 was used to detect the proliferation rate of macrophages. Results:Mtb infection significantly increased the expression of PPARγ in macrophages ( P<0.001), promoted intracellular lipid aggregation and CD36 expression and decreased the levels of TC, TG, LDL-C and HDL-C in the supernatant of cell culture ( P<0.001) and cell proliferation rate ( P<0.001). PPARγ agonist significantly enhanced the intracellular lipid accumulation and CD36 expression that were induced by Mtb infection and down-regulated the lipid level in the supernatant of cell culture and cell proliferation rate, while PPARγ antagonist reversed the above effects. Conclusions:PPARγ played a role in lipid metabolism in Mtb-infected macrophages through affecting CD36 expression.
ABSTRACT
Objective:To analyze the relationship between heart rate variability (HRV) and cardiac function and prognosis in patients with Parkinson′s disease (PD) and chronic heart failure (CHF).Methods:60 patients with PD and CHF admitted to our hospital from January 2018 to December 2019 were selected as group A. 50 patients with simple PD admitted in the same period were selected as group B , and 40 patients in the healthy control group were selected as group C. The high frequency (HF), low frequency (LF), high frequency and low frequency ratio (HF/LF), left ventricular ejection fraction (LVEF) were monitored in the three groups, and the incidence and mortality of cardiovascular events such as acute coronary syndrome, malignant arrhythmia and acute heart failure were recorded during six months follow-up.Results:The HF, HF/LF ratio and LVEF of group C were significantly higher than those of group A and B, and LF value was significantly lower than that of group A and B ( P<0.05). The HF, HF/LF ratio and LVEF of group B were significantly higher than those of group A, and LF value was significantly lower than that of group A ( P<0.05). The HF and HF/LF ratio of patients with LVEF≥50% in group A was significantly higher than those with LVEF<50%, and LF was significantly lower than those with LVEF<50% ( P<0.05). The HF and HF/LF values of the patients in group A who died and had cardiovascular events were significantly lower than those of the surviving patients and those without cardiovascular events, and the LF values were significantly higher than those of the surviving patients and those without cardiovascular events ( P<0.05). The HF and HF/LF value of group A was positively correlated with LVEF value ( r HF=0.883, rHF/ LF=0.854, P<0.05), and negatively correlated with mortality ( r HF=-0.819, rHF/ LF=-0.802, P<0.05) and cardiovascular events ( r HF=-0.736, rHF/ LF=-0.794, P<0.05) ; LF value was negatively correlated with LVEF value ( r=-0.743, P<0.05). LF value was positively correlated with mortality ( r=0.743, P<0.05) and the incidence of cardiovascular event ( r=0.750, P<0.05). Conclusions:The decrease of HRV in PD patients with CHF will weaken their cardiac function and increase their adverse prognosis. Therefore, the monitoring of HRV is helpful for the treatment and prognosis intervention in PD patients with CHF.
ABSTRACT
OBJECTIVE@#To explore the genetic basis for a patient with episodic ataxia and pyramidal tract signs.@*METHODS@#The patient was subjected to high-throughput sequencing, Sanger sequencing and analysis of dynamic variant site associated with spinocerebellar ataxias (SCA).@*RESULTS@#The patient was an adolescent male presenting with episodic ataxia, bilateral knee hyper-reflexia and ankle clonus. By genetic testing, he was found to harbor a c.1159-1162dupAAGT variant of PDHA1 gene. The same variant was not found in his parents and elder sister. No abnormalities were found by SCA dynamic variant screening. The patient was diagnosed as pyruvate dehydrogenase E1alpha deficiency due to variant of the PDHA1 gene.@*CONCLUSION@#The de novo c.1159-1162dupAAGT variant of the PDHA1 gene probably underlies the disease in the proband. Patients with pyruvate dehydrogenase E1alpha deficiency have complex phenotypes and very few have pyramidal tract involvement, which may be attributed to abnormal early neuronal development.
ABSTRACT
@#Objective To investigate the changes of plasma glial fibrillary acidic protein (GFAP) in patients with Alzheimer ’s disease (AD) and its correlation with cognitive impairment. Methods asma GFAP levels were analyzed in 34 AD patients and 38 normal controls. We investigated the differences in plasma GFAP levels between the two groups,and analyze the relationship between plasma levels of GFAP and cognitive function. Results The plasma GFAP level in the AD patients [1253(964~1584) pg/ml] was significantly higher than that in the normal controls [874(698~1079)](P<0.001). Plasma GFAP levels might be helpful to the identification of AD from normal control with a sensitivity of 58.8% and a specificity of 86.8%. Plasma GFAP levels correlated with the mini-mental state examination (r=-0.42,P<0.001) and Montreal cognitive assessment score (r=-0.38,P<0.001). Conclusion Plasma GFAP might be a potential biomarker in the differential diagnosis and evaluation of AD,and it is worthy of further study.

ABSTRACT
Objective To investigate the relationship between baseline serum uric acid and the severity of coronary artery disease ( CAD ) in the first-degree relatives or non-first-degree relatives of men with type 2 diabetes. Methods Three hundred and eighty-one men with negative coronary angiography for the first time were divided into diabetes and non-diabetes groups and followed-up for 5 years. The primary outcome was acute coronary syndrome suspected during subsequent 5 years, and the coronary angiography was conducted simultaneously. The severity of CAD was assessed by the coronary stenosis index ( CSI) and the number of coronary lesion vessels. Results In normal blood glucose group, serum uric acid was higher in the first-degree relatives of diabetics compared with non-first-degree relatives(P<0. 01), along with higher morbidity of CAD, CSI, and coronary lesion vessels (all P<0.01). Correlation analysis showed that CSI(r=0. 250, P=0. 041) and coronary lesion vessels(r=0. 252, P=0. 040) in non-diabetics group were associated with baseline levels of serum uric acid. Conclusion The elevation of serum uric acid was closely related to subsequent CAD, especially in first-degree relatives of male with type 2 diabetes, which could be used as an early indicator for CAD prediction.

Objective To investigate the expressions of apoptosis stimulating protein of P53 (ASPP)family in colorectal carcinoma tissue and to explore their relationship with the clinicopathological characteristics of colorectal carcinoma,and to clarify the effect of ASPP family in the development of colorectal carcinoma.Methods 45 cases of colorectal carcinoma tissue and 20 cases of healthy controls were selected. Among 45 cases of colorectal carcinoma tissue, there were 1 1 cases of well differentiated colorectal carcinoma, 2 1 cases of moderately differentiated colorectal carcinoma,and 13 cases of poorly differentiated colorectal carcinoma;7 cases of T1 stage colorectal carcinoma,8 cases of T2 stage colorectal carcinoma,25 cases of T3 stage colorectal carcinoma,and 5 cases of T4 stage colorectal carcinoma;19 cases of N1 stage with lymph node metastasis,26 cases of N0 stage without lymph node metatasis.The expressions of ASPP1,ASPP2,and iASPP in 45 cases of colorectal carcinoma tissue and 20 cases of normal colon tissue were detected by immunohitochemistry SP method,and the correlations between the expressions of ASPP family and the pathologic typing,infiltrative depth,and lymph node metastasis of colorectal carcinoma were analyzed. Results ①The immunohitochemical staining results showed that the ASPP family members expressed in colorectal carcinoma tissue and normal colon tissue, and there were no significant differences in ASPP1 and ASPP2 positive rates between colorectal carcinoma tissue and normal colon tissue (P>0.05);the positive expression rate of iASPP in colon cancer tissue was higher than that in normal colon tissue (P0.05);the expression of ASPP2 positive rate was decreased when the differentiation degree of tumor cells reduced,they had positive correlation (rs=0.454,P=0.002);the expression of iASPP in colon cancer tissue had no correlation with the differentiation degree of tumor cells (rs=-0.171,P>0.05).③ The expression of ASPP1 in colon caner tissue had no correlation with the infiltrative depth of tumor (rs=-0.268,P>0.05);the expression of ASPP2 positive rate was decreased when the tumor infiltrative depth increased,they had negative correlation (rs=-0.348,P0.05).④The expressions of ASPP1,ASPP2, and iASPP in colon caner tissue had no correlation with lymph node metastasis (rs=0.089,rs=0.044,rs=0.210, P>0.05).Conclusion The expression levels of iASPP in colon cancer and normal colon tissues are different,it may be useful for the diagnosis, differential diagnosis and evaluation in benign and malignant colorectal diseases. The expression of iASPP is negatively correlated with the pathologic typing and neoplasm staging of colorectal carcinoma,it indicates that iASPP can be used as a indicator in judging the prognosis of colorectal carcinoma.
ABSTRACT
Objective To study the value of EUS-FNA cytology and fluid carcinoembryonic antigen (CEA) for differential diagnosis of malignant and benign pancreatic cystic lesions.Methods Data of 27 patients who underwent EUS-FNA were reviewed.According to Youden exponent,the optimal cut-off points for cyst fluid CEA were determined by receiver operating characteristic (ROC) curve.Compared with surgical pathology,the accuracy,sensitivity,specificity,positive predictive value (PPV) and negative predictive value (NPV) of the EUS imaging,cytology as well as cyst fluid CEA were determined.Results Of the 27 cases,14 were diagnosed as benign lesions,13 were diagnosed as malignant or premalignant lesions.The accuracy,sensitivity,specificity,PPV and NPV of EUS imaging were 77.8% (21/27),69.2%(9/13),85.7% (12/14),81.8% (9/11) and 75.0% (12/16).The accuracy,sensitivity,specificity,PPV and NPV of EUS-FNA cytology were 85.2% (23/27),76.9% (10/13),92.9% (13/14),90.9% (10/11),and 81.3% (13/16).The corresponding values of fluid carcinoembryonic antigen under the ROCderived ideal cut-off were 74.1% (20/27),84.6% (11/13),64.3% (9/14),68.8% (11/16) and 81.8% (9/11) (CEA > 22.24 ng/ml).Conclusion EUS-FNA cytology is highly accurate and specific for differential diagnosis of malignant and benign pancreatic cystic lesions.Cyst fluid CEA shows better sensitivity.EUS-FNA cytology and cyst fluid CEA analysis can basically meet the requirement of differentiating the benign and (pre)malignant pancreatic cystic lesions.
