ABSTRACT
Objective:To evaluate the clinical value of NG-Test Carba5 for rapid detection of carbapenemases produced by carbapenem-resistant Enterobacteriaceae (CRE) strains. Methods:A total of 1 210 CRE strains were collected during 2018-2022 from 77 hospitals in 21 provinces of China and were subjected to NG-Test Carba5 for rapid detection of carbapenemase. The whole genome sequencing (WGS) analysis was referenced as the gold standard method.Results:Overall, the NG-Test Carba5 demonstrated excellent performance in detection of five kinds of carbapenemases [Klebsiella pneumoniae carbapenemase (KPC), New Delhi metallo-β-lactamase (NDM), imipenemase metallo-β-lactamase (IMP), Verona integron-encoded metallo-beta-lactamase (VIM) and oxacillinase-48-type carbapenemases(OXA-48)] from CRE strains, with a sensitivity of 98.47% (1 161/1 179), specificity of 100% (31/31), and positive predictive value of 100% (1 161/1 161). The sensitivity for detection of NDM, IMP, OXA and VIM reached 100% (307/307), and 97.70% (763/781) for KPC. For 11 strains carrying blaKPC-25, blaKPC-78, or blaKPC-93, NG-Test Carba5 reported positive KPC detection (11/11). For strains carrying blaKPC-33 and blaKPC-77, however, NG-Test Carba5 delivered negative results. Additionally, for those strains co-producing two or three kinds of carbapenemases, NG-Test Carba5 was able to report all of the targets with a sensitivity of 100% (91/91). Conclusions:NG-Test Carba5 showed excellent performance in rapid and accurate detection of carbapenemases from CRE strains. Nonetheless, for those strains with negative results, some other phenotypic and genotypic methods should be implemented alongside to avoid missing targets.
ABSTRACT
Objective:To explore the threshold and diagnostic value of Chinese version of the Chelsea Physical Function Assessment Tool (CPAx-Chi) for ICU acquired weakness(ICU-AW).Methods:To learn the details and precautions of the CPAx-Chi scale, and then two researchers used the CPAx-Chi scale and MRC-Score scale to independently evaluate 200 patients who come from a comprehensive ICU in a top first-class hospital in Gansu Province simultaneously. The best cut-off point and value of the CPAx-Chi scale in the diagnosis of ICU-AW were determined by calculating the Receiver Operating Characteristic (ROC) curve, the Youden index(YI) and the consistency test that are all based on the MRC-Score≤48.Results:The ROC Area Under Curve(AUC) of the CPAx-Chi scale diagnosis ICU-AW which based on the MRC-Score≤48 were as follows: ROC AUC of group A was 0.899 (95% CI 0.862-1.025); ROC AUC of group B was 0.874 (95% CI 0.824-0.925). When the best cut-off point of CPAx-Chi scale for diagnosis ICU-AW was 31.5, the maximum YI=0.643, the sensitivity was 87%, and the specificity was 77% in group A; and the maximum YI= 0.62, the sensitivity was 75%, and the specificity was 87% in group B. Meanwhile, when the best cut-off point of CPAx-Chi scale for diagnosis ICU-AW was 30.5, the maximum YI=0.62, the sensitivity was 79%, and the specificity was 83% in group B. Taking the CPAx -Chi≤31 as the best cut-off point, the score differences in ICU-AW group and the non-ICU-AW group were not detected, A group ( F value was 4.53, P=0.035) or B group ( F value was 6.51, P=0.011). The consistency of CPAx -Chi≤31 and MRC-Score≤48 in the diagnosis of ICU-AW was high, and the Kappa=0.845 ( P=0.02) in the group A; the Kappa=0.839( P=0.04) in the group B, and the group differences were detected. Conclusions:CPAx-Chi≤31 is the best cut-off point for diagnosing ICU-AW, and has good sensitivity and specificity. CPAx-Chi scale can be popularized and applied in the critical care medicine in China.
ABSTRACT
Decision-making aid for cancer patients is of great significance in the diagnosis and treatment for diseases. Breast cancer is one of the most common malignant tumors in women all over the world, and breast cancer patients have become the main target population for decision-aided research. Application of decision-making assistance for patients in Western countries has developed to a certain extent, while relevant research in China is still at the early stage. There are kinds of intervention forms for patients' decision aids, including traditional brochures and videos, decision aids systems, decision coaching, multidisciplinary breast cancer teams, etc. The tools for decision-making quality evaluation include the patients' awareness for decision-making, participation, decision-making conflict, decision-making satisfaction, decision-making regret, which can provide important guidance for the application of decision-making aid treatment in breast cancer patients in the future.

Objective:To investigate the current status of intensive care unit-acquired weakness (ICU-AW) assessment, analyze the assessment barriers, and to provide reference to improve ICU-AW assessment.Methods:A convenient sampling cross-sectional survey was conducted. First, an interview outline which based on related domestic and international literatures and combining with the research purpose of this study were designed. Thirteen medical personnel (8 ICU nurses, 3 ICU doctors, 1 respiratory therapist and 1 physiotherapist) who worked in the intensive care unit (ICU) of the First Hospital of Lanzhou University were enrolled with convenience sampling method to interview. Second, the topics were comprehensively analyzed and extracted, and then a questionnaire was constructed, and the reliability and validity was assessed. Finally, the questionnaire survey including the general situation of ICU medical staffs, the current practices of ICU-AW and influencing factors was implemented in China.Results:The retest reliability was 0.92 and expert validity was 0.96 of the questionnaire. There were 3 563 respondents in 31 provinces, municipalities and autonomous regions which eliminated 357 unqualified questionnaires, including 173 respondents from neonatal or pediatric ICU, 89 respondents whose working time was less than 6 months, and 95 invalid respondents, and then there were finally 3 206 valid questionnaires and the response rate were 90.0%. Those 3 206 respondents included 616 doctors (19.2%), 2 371 nurses (74.0%), 129 respiratory therapists (4.0%), 51 physiotherapist (1.6%) and 39 dietitians (1.2%). The mean age was (30.7±6.3) years old. Most of them had bachelor's degree (65.9%), master and above was 14.1%. Associate senior physician and above was 8.0%; ICU working time was (5.94±4.50) years. In clinical practice, only 26.5% of the ICU medical staffs confirmed that they had treated or taken care for ICU-AW patients; 52.9% of medical staffs evaluated ICU-AW only based on clinical experience, and only 12.3% used ICU-AW assessment tools. The majority of respondents believed that ICU-AW knowledge training should be performed (81.8%), ICU-AW assessment should be as important as other complications (pressure sore, infected ventilator associated pneumonia, etc., 75.1%), and ICU-AW assessment should be part of daily treatment and care activities (61.2%). However, only 10.2% of respondents had received ICU-AW related knowledge training, and 42.7% respondents believed that their ICU-AW related knowledge could not meet clinical needs. Only 18.7% respondents would actively assess whether patients suffered from ICU-AW or not, and 42.3% respondents thought that ICU-AW should be assessed every day, and the assessment tools were also inconsistent. There were 44.0% respondents considered the Medical Research Council Muscle score (MRC-score) scale was the optimal tool for diagnosing ICU-AW, the following were neuro-electrophysiological examination (17.2%) and manual muscle strength (MMT, 11.1%). The main cause of the ICU-AW assessment barriers was the lack of ICU-AW related knowledge (88.1%), and the following were lack of ICU-AW assessment guidelines (76.5%), patients' cognitive impairment or limited understanding ability (84.6%), unable to cooperate with the assessment due to critical illness (83.0%), and inadequate attention to ICU-AW assessment by the department (77.5%).Conclusion:The current status of ICU-AW assessment were unsatisfying in China, and the main barriers were lack of skills and knowledge.
ABSTRACT
Objective:To investigate the cognitive impairment after intensive care unit (ICU) discharge and provide theoretical basis for prevention and intervention.Methods:Studies about cognitive impairment after ICU discharge were retrieved in PubMed, Embase, Cochrane Library, Web of Science, Wanfang data, CNKI and SinoMed from their foundation to December 2019. The literature screening and data extraction were performed by two researchers independently, and the quality of different types of researches was evaluated using Cochrane Handbook 5.1.0, Newcastle-Ottawa scale (NOS) and agency for healthcare research and quality criteria (AHRQ). The Meta-analysis was performed by Stata 13.0 software. Sensitivity analysis was used to determine the reliability of the combined effect values. Funnel plot and Egger test were used to analyze publication bias. The non-parametric clipping was used to evaluate the impact of publication bias on the results.Results:A total of 35 studies were enrolled, including 27 prospective cohort studies, 4 retrospective cohort studies, 2 randomized controlled trial (RCT) studies, 1 case-control study, and 1 cross-sectional study. Three literatures were published in Chinese and 32 were in English, which covered 13 countries, and a total of 102 504 ICU survivors were followed up successfully. Literature quality evaluation results showed that the NOS scores of 31 cohort studies were between 6 and 9, of which the case-control study scored 9. The quality grade of 2 RCT studies were both B. According to the AHRQ criteria, 1 cross-sectional study's design was scientifically rigorous and of high quality. Thirty-five studies reported that the overall incidence of cognitive impairment after ICU discharge ranged from 2.47% to 66.07%. For the multiple follow-ups studies, the first survey data was selected for Meta-analysis, and the results showed that the pooled incidence was 38.44% [95% confidence interval (95% CI) was 29.32-47.55]. Each study was removed for sensitivity analysis and the pooled results did not change much, which indicated that the results were reliable. The sub-group analysis was performed on different evaluation methods for cognitive impairment after ICU discharge, different types of ICU patients, and different follow-up time. The results showed that the pooled incidence of studies using neuropsychological test to evaluate cognitive impairment after ICU discharge was 31.42% (95% CI was 21.82-41.02), the pooled incidence of studies using questionnaires or scales was 38.75% (95% CI was 29.54-47.96), and the difference between the two groups was statistically significant ( P < 0.01). The pooled incidence of cognitive impairment after ICU discharge in general ICU patients was 43.42% (95% CI was 30.88-55.95), acute respiratory distress syndrome (ARDS) patients' pooled incidence was 34.40% (95% CI was 23.02-45.79), and the pooled incidence of elderly ICU patients was 12.93% (95% CI was 8.48-17.37), the difference among the three groups was statistically significant ( P < 0.01). The incidences of cognitive impairment < 1 year, 1 to 4 years, ≥ 5 years after ICU discharge were 43.30% (95% CI was 29.47-57.13), 34.21% (95% CI was 26.70-41.72), and 20.22% (95% CI was 4.89-35.55), respectively, and the differences among the three groups were statistically significant ( P < 0.01). The funnel plot showed that the distribution of all studies was asymmetric, and the Egger test result also suggested that there might be publication bias ( P < 0.05). The non-parametric clipping was used to estimate the impact of publication bias on the results, and the result showed that the difference in the incidence of cognitive impairment after ICU discharge before and after non-parametric clipping was large, suggesting that publication bias might influence the stability of the research results. Conclusions:The incidence of cognitive impairment after ICU discharge is relatively high and persistent for a long time, but diagnostic criteria of cognitive impairment and follow-up time are quite different. It is necessary to develop consistent evaluation criteria and rigorous designed research in the further.
ABSTRACT
Objective To determine the safety criteria for early goal-oriented rehabilition exercise in patients undergoing mechanical ventilation in intensive care unit (ICU) by systematic review.Methods Randomized controlled trails (RCTs) and cohort studies about early goal-oriented rehabilition exercise in patients undergoing mechanical ventilation in ICU were retrieved in CBM,CNKI,Wanfang Data,PubMed,Cochrane Library and Web of Science from their foundation to March 2018,and other sources as supplement was also retrieved.The intervention program of RCT study was ICU routine nursing in control group,early activity in observation group,and early activity in cohort study without control group.Early activities included active and passive activities on the bed,sitting upright,bed-chair transfer,standing and walking.Literature screening and data extraction were performed independently by two researchers.Variables or parameters.related to cardiovascular,respiratory,nervous,orthopedic and other systems were collected for safety criteria.Variables or parameters used in at least three literatures were collected for each system.Cochrane 5.1.0 was used to evaluate the quality of RCT study,and Newcastle-Ottawa scale (NOS) was used to evaluate the quality of cohort study.Results A total of 24 articles about early activity of patients undergoing mechanical ventilation in ICU were enrolled,involving 4647 patients,including 11 RCT studies involving 1 031 patients,509 in control group and 522 in observation group;13 cohort studies including 3616 patients.It was shown by systematic review that safety criteria for early activity in patients undergoing mechanical ventilation in ICU involved five systems,20 variables or parameters.The cardiovascular system included 8 variables or parameters,such as 40 bpm ＜ heart rate (HR) ＜ 130 bpm (n =4),hemodynamic stability (n =5),no myocardial infarction (n =3),no arrhythmia (n =4),no vascular active drugs (n =4),90 mmHg ＜ systolic blood pressure (SBP) ＜ 200 mmHg (1 mmHg =0.133 kPa,n =4),65 mmHg ≤ mean arterial pressure (MAP) ≤ 110 mmHg (n =3),no history of cardiopulmonary resuscitation (CPR,n =5).The respiratory system included 4 variables or parameters,involving 5 times/min ＜ respiratory rate (RR) ＜ 40 times/min (n =5),fraction of inspired oxygen (FiO2) ≤ 0.60 and positive end-expiratory pressure (PEEP) ≤ 10 cmH2O (1 cmH2O =0.098 kPa,n =4),FiO2 ＜ 0.60 or PEEP ＜ 10 cmH2O (n =3),pulse blood oxygenation (SpO2) ＞ 0.88 (n =5).The nervous system included 4 variables,including no neuromuscular disease (n =7),no increase in intracranial pressure (n =7),no coma (n =4),understand and do the right thing (n =4).The orthopedic system included 2 variables,including no fracture (n =3),no unstable fracture (n =8).Other factors included 2 variables,including no open abdomen wound (n =4),and no palliative care (n =3).Conclusions This study identified safety criteria for early goal-directed rehabilition exercise in patients undergoing mechanical ventilation in ICU included five systems of cardiovascular,respiratory,neurological,orthopedic,and other systems,in which cardiovascular and respiratory systems were the most frequently cited variables or parameters.The consistency of each system security criteria or variables reported by different literatures was high,but the parameters need to be further verified by high-quality study.
ABSTRACT
Objective To explore effective and objective diagnostic tools for evaluating intensive care unit acquired weakness (ICUAW). Methods The studies about evaluation and diagnosis of adult ICUAW in PubMed, Embase, Web of Science, the Cochrane Library, CNKI, CBM, VIP and Wanfang databases from the date of their foundation to July 1st in 2018 were retrieved by computer. The literatures in Chinese and English were searched. Two investigators independently screened literature and evaluated the literature quality ratings, and extracted the research design, sample size, research object, evaluation item, reliability, validity, clinical application and other indicators, and then systematically analyzed the reliability and validity of ICUAW diagnostic tools, and evaluated diagnostic tools' advantages, disadvantages and application status. Results There were 19 literatures including 14 assessment scales and ultrasound diagnosis. The 14 assessment scales were medical research council score (MRC-Score), Barthel index (BI), 6-minute walk test (6MWT), clinical outcome variables scale (COVS), the Chelsea critical care physical assessment tool (CPAx), functional independence measure (FIM), functional status score for the intensive care unit (FSS-ICU), the ICU mobility scale (IMS), rivermead mobility index (RMI), the Perme ICU score (PERME), the physical function ICU test (PFIT), the physical function ICU test score (PFIT-s), the surgical ICU optimal mobility score (SOMS), and the Manchester mobility score (MMS). Nine scales (60%) were tested reliability and the rang of inter-rater reliability was 0.600-0.996, and the test reliability was 0.970, and the range of internal consistency reliability was 0.680-0.992. Validity of 6 scales (40%) were evaluated, and the range of structure validity was 0.57-0.94, the range of content validity was 0.830-0.988, the range of concurrent validity was 0.730-0.823. It was shown that the reliability of ICUAW assessment scale was relatively good at present, but the degree of accurate assessment of ICUAW was relatively low. The evaluation content of ICUAW can be divided into three categories: in the first, they measured the muscles strength of body just like MRC-Score; in the second, they evaluated the physical function and mobility, such as COVS, CPAx, FIM, FSS-ICU, IMS, PERME, PFIT, RMI, SOMS and MMS; in the third, they evaluated daily activity and physiology parameter just as 6MWT, BI and ultrasound. Different scales were correlated with the length of ICU stay (ICU-LOS), the hospital discharge, and the mortality. For example: COVS, CPAx, FSS-ICU, PFIT, PFIT-s and SOMS could predict the ICU-LOS and hospital discharge, RMI and SOMS can predict patient mortality. However, there was no evidence to testify the consistency between them. Now, the specialist consensus about the observation nodes of threshold and electrophysiological records were the complex action potential (CMAP) range < 0.43-0.65 mV and the sensory nerve action potential (SNAP) range < 17.6 μV. Conclusions There are many diagnostic tools in ICUAW, and the reliability of each scale is relatively good. In future studies, we should collect the advantages of each scale, explore the specific indicators to evaluate ICUAW and improve the accuracy and validity of diagnostic ICUAW.
ABSTRACT
Background and purpose:Microsatellite instability (MSI) status is commonly applied to predict the prognosis and chemosensitivity in stage Ⅱ and stage Ⅲ colorectal cancer patients. However, researches of its function on metastasis colorectal cancer are limited. This study investigated its value on prognosis and chemosensitivity in metastatic colorectal cancer (CRC) patients.Methods:We retrospectively investigated tumor tissues from metastasis CRC patients who were treated with oxaliplatin and 5-FU-based therapy regimens (FOLFOX and XELOX). Immunostaining of proteins of the mismatch repair genehMLH1,hMSH2,hMSH6 andhPMS2 was performed. Prognostic value and chemosensitivity in patients with MSI status were also determined.Results:Clinical features from 113 patients were analyzed. No cor-relation of overall survival (OS) and chemosensitivity with MSI status was found. We further investigated 79 patients with synchronous metastasis and palliatively tumor resection. Median progression free survival (PFS) from 22 MSI patients was significant longer than that in 57 MSS patients (19.9 monthsvs 7 months,P=0.005). No significant difference was seen in OS comparison (P=0.07). MSI status was also an independent prognostic factors of PFS by Cox multivariate analysis (MSS/MSI,HR=2.079,P=0.043). Moreover, in this group, MSI patients had improved disease control rate (59.1%vs 31.6%, P=0.025) in chemosensitivity analysis than MSS patients.Conclusion:A better PFS in MSI patients with synchronous metastasis and palliative tumor resection was found after treated with oxaliplatin and 5-FU-based therapy and a better chemosensitivity in MSI patients was also found.
ABSTRACT
Objective To investigate folic acid and vitamin B12 on the plasma homocysteine (Hcy) levels and neurological function in young and middle-aged acute ischemic stroke patients with hyperhomocysteinemia (HHcy).Methods Young and middle-aged acute ischemic stroke patients with HHcy were enrolled.They were randomly divided into either an intervention group or a control group.The patients with cerebral infarction in both groups were treated with conventional treatment.At the same time,the patients in the intervention group were treated with folic acid 5 mg and vitamin B12 25 μg,3 times a day for 4 weeks.Those in the control group were given placebo.The next day after admission and thereafter,the plasma Hcy levels were determined once every week.At the time of admission and after 4-week treatment,the National Institutes of Health Stroke Scale (NIHSS) was used to evaluate neurological deficits.Results A total of 78young and middle-aged acute lschemic stroke patients with HHcy were enrolled (n =39 in each group).The baseline plasma Hcy levels and the NIHSS scores in all patients had significant linear correlation (r =0.717;P＜0.01).Four weeks after treatment,the plasma Hcy levels of the intervention group were significantly lower than those of the control group (15.07 ± 2.01μmol/L vs.21.29 ± 2.48 μmol/L; t =4.539; P ＜0.05),but there was no significant difference in the NIHSS scores (4.87 ± 2.17 vs.5.13 ± 1.67; t =0.585,P =0.560).Conclusions The baseline plasma Hcy level was positively correlated with the severity of stroke.Folic acid in combination with vitamin B12 could effectively decrease the plasma Hey level in young and middle-aged acute ischemic stroke patients with HHcy,but it had no significant effect on the improvement of neurological function.
ABSTRACT
Objective To investigate the clinical features,etiology and risk factors of the inpatients with ischemic stroke in the Department of Cardiology.Methods The medical records of the inpatients with ischemic stroke and the inpatients in a control group were collected retrospectively.The demographics,vascular risk factors,clinical features,and other related factors were compared in both groups.Multivariate logistic regression analysis was used to analyze the independent risk factors for in-hospital ischemic stroke in the Department of Cardiology.Results A total of 2 789 inpatients in departments of cardiology were enrolled,and 26 of them (0.93％) had in-hospital stroke.One hundred thirty inpatients from 2 763 patients without in-hospital stroke were used randomly as control cases.The proportions of the inpatients of hypertension (73.08％ vs.50.77％ ; x2=4.348,P=0.037),atrial fibrillation (50.00％ vs.15.38％; x2=15.56,P=0.000),infection (30.77％ vs.7.69％ ; x2 =11.304,P =0.003),smoking (46.15％ vs.21.54％ ; x2 =6.886,P =0.009),alcohol (26.92％ vs.11.54％ ;x2 ＝ 4.233,P =0.040),previous stroke history (19.23％ vs.4.61％ ;x2 =7.062,P =0.008),and taking anti-hypertensive drugs (42.31％ vs.21.54％ ;x2 =4.985,P =0.026),as well as systolic blood pressure (143.43 ± 18.59 mm Hgvs.129.52 ± 23.52 mm Hg; t =3.209,P=0.003; 1 mmHg =0.133 kPa),diastolic blood pressure (88.77± 11.35 mm Hg vs.77.55± 14.60 mmHg; t=2.421,P =0.020),and homocysteine levels (19.27 ± 11.08 μnol/L vs.15.30 ±5.25 μmol/L; t =2.814,P =0.006) in the stroke group were significantly higher than those in the control group in the Department of Cardiology.Multivariate logistic regression analysis showed that atrial fibrillation (odds ratio [OR] 3.310,95％ confidence interval [CI] 1.207-9.076; P =0.020),infection (OR 3.270,95％ CI 1.024-10.438; P =0.045),systolic blood pressure (OR 1.023,95％ Cl 1.002-1.045; P =0.031),and homocysteine level (OR 1.089,95％ CI 1.009-1.175; P =0.029) were the independent risk factors for in-hospital ischemic stroke in the Department of Cardiology.Conclusions Atrial fibrillation,infection,systolic blood pressure,and high homocysteine levels are the independent risk factor for in-hospital ischemic stroke in the Department of Cardiology.Active intervention and control these risk factors may have great significance for reducing its risk.
ABSTRACT
Objective To investigate hemorrhagic transformation (HT) and outcomes in acute ischemic stroke.Methods The demographics,vascular risk factors,imaging and other clinical data in patients with acute ischemic acute were collected retrospectively and compared.Using the susceptibility weighted imaging (SWI) to diagnose HT,and the patients were divided into either a HT group or a non-HT group.The modified Rankin scale was used to evaluate the clinical outcomes.Multivariate logistic regression analysis was used to determine the independent risk factors for HT and poor outcome in HT patients.Results A total of 96 patients with acute ischemic stroke were enrolled and 34 of them had HT (35.4％).The age (66.21 ± 7.04 years vs.61.21 ±13.42 years; t =2.020,P=0.046) and infarct volume (3.88 ±2.20 cm3 vs.1.96 ± 1.37 cm3; t =5.67,P=0.001) in the HT group were significantly older or larger than those in the non-HT group.The proportions of hypertension (58.8％ vs.30.6％;x2 =7.228,P=0.007),diabetes (29.4％ vs.6.5％;x2 =9.293,P=0.002),atrial fibrillation (35.3％ vs.3.2％;x2=18.128,P=0.000),and cardiogenic cerebral embolism (35.3％ vs.3.2％ ; P =0.000) were significantly higher than those in the non-HT group,while the proportion of small arterial occlusive stroke was significantly lower than that in the non-HT group (38.2％ vs.62.9％ ;P =0.032).Multivariate logistic regression analysis showed that age (odds ratio [OR] 1.168,95％ confidence interval [CI] 1.059-3.412; P =0.021),infarct volume (OR 3.461,95 ％ CI 1.317-6.270; P =0.044) and atrial fibrillation (OR 1.284,95％ CI 1.117-2.903; P =0.015) were the independent risk factors for HT.In the HT patients,age (69.46 ±7.17 years vs.64.19 ±6.31 years; t =2.248,P =0.032) in the poor outcome group was significantly older than that in the good outcome group.The proportions of hypertension (84.6％ vs.42.9％ ;x2 =781,P =0.016),diabetes (50.0％ vs.14.3％ ;x2 =6.053,P =0.014),cardiogenic cerebral embolism (61.5％ vs.19.0％ ; P =0.025) and hematoma HT (76.9％ vs.19.0％ ;x2 =11.104,P =0.001) were significantly higher than those in the good outcome group.Multivariate logistic regression analysis showed that the diabetes (OR 2.151,95％ CI 1.179-3.218; P =0.023),atrial fibrillation (OR 4.136,95％ CI1.010 to 8.413; P =0.046) and hernatoma HT (OR 2.134,95％ CI 1.219-4.452; P =0.039) were the independent risk factors for the poor outcomes of HT patients at 3 months after symptom onset.Conelusions The incidence of HT in patients with acute ischemic stroke was 35.4％.Age,infarct volume and atrial fibrillation were the independent risk factors for HT,and diabetes,atrial fibrillation and hematoma HT were the independent risk factors for the poor outcomes in HT patients at 3 months after symptom onset.
ABSTRACT
The occurrence of stroke in patients and a variety of underlying diseases during the hospitalization are associated with the treatment, they often result in the aggravation of disease, poor prognosis, and medical disputes. Theoretically, the timeliness of diagnosis and treatment of in-hospital strokes are superior to those outside hospitals, but it still has the widespread delay in the actual diagnosis and treatment. This article reviews the possible causes and mechanisms of in-hospital stroke in order to raise awareness of prevention of in-hospital stroke, prevent and eliminate the potential risks of in-hospital stroke.
ABSTRACT
Previous studies have agreed that the levels of neuron-specific enolase (NSE)and S100B protein have an important value for the severity of cerebral infarction and prognosis estimation. This article reviews the relationship between the serological changes of NSE and S100B and cerebral infarction, infarct volume, severity of neurological deficits, infarct location,and prognosis, as well as the advances in research on the evaluation of therapeutic drugs.

ABSTRACT
Uncoupling protein, a protein that participates in proton transport in the inner mitochondrial membrane, has some physiologic functions such as regulating thermogenesis, maintaining body temperature, regulating energy balance and adenosine triphosphate production, controlling reactive oxygen species production, and restraining apoptosis. It takes part in the pathophysiological processes in a number of diseases. The article reviews the uncoupling protein gene, distribution and regulation, the roles in peripheral tissues and central nervous system, and its possible relationship with cerebral infarction.
