Objective To investigate the clinical characteristics and associated risk factors for patients with mixed Candida/bacterial bloodstream infections (BSIs). Methods A retrospective study was conducted in the Second Affiliated hHospital of Zhejiang University School of Medicine from February 2012 to June 2015. The clinical data of cases was collected, and the clinical characteristics, the microbiology data and outcomes in patients with mixed Candida/bacterial BSIs confirmed by blood culture were compared with those with candidaemia. A Logistic regression analysis was performed to investigate the independent risk factors. Results A total of 136 candidaemia cases were analyzed including 40 cases (29.4%) of mixed Candida/bacterial BSIs and 96 cases of candidaemia. Among the 136 candidas strains, the proportion of non-albicans exceeded the albicans (50.7% vs 49.3%), although the later was still the predominant one. There was no significant difference in the distribution of candidas strains between patients with mixed Candida/bacterial BSIs and patients with candidaemia. In patients with mixed Candida/bacterial BSIs, 25 strains (61.0%) of gram-positive cocci and 16 strains (39.0%) of gram-negative bacilli were isolated. Compared with patients with candidaemia, patients with mixed Candida/bacterial BSIs needed longer period of antifungal therapy [12.0 (4.0-25.0)days vs 7.0 (3.0-13.5) days, P=0.027], but the crude 30-day and 90-day mortality did not differ between the two groups (40.0% vs 32.3%; 45.0% vs 36.5%; both P>0.05). Univariate analysis revealed that the prior hospital stay, ICU admission at the onset of candidaemia, blood transfusion, human albumin infusion, mechanical ventilation, linezolid use and high SOFA score were related with the occurrence of mixed Candida/bacterial BSIs (all P<0.05). Multivariate analysis showed that only high SOFA score was the independent risk factor (P=0.003). Conclusions Gram-positive cocci were the predominant species in mixed Candida/bacterial BSIs. Compared with candidaemia, mixed Candida/bacterial BSIs needs a longer ICU stay, a longer hospital stay, and a prolonged antifungal therapy. High SOFA score is the independent risk factor for mixed Candida/bacterial BSIs.

目的探讨念珠菌/细菌混合性血流感染(BSIs)的临床特点及相关危险因素。方法对2012年2月至2015年6月在浙江大学医学院附属第二医院就诊的患者进行回顾性研究。收集病例的临床数据,并将血液培养证实的念珠菌/细菌混合型BSI患者与念珠菌血症患者的临床特征、微生物学数据和结果进行比较。进行Logistic回归分析,以调查独立的危险因素。结果共分析了136例念珠菌血症病例,其中念珠菌/细菌混合型BSI 40例(29.4%),念珠菌血症96例。在136株候选菌株中,非白色念珠菌的比例超过了白色念珠菌(50.7%对49.3%),尽管后者仍然是主要菌株。念珠菌/细菌混合型BSI患者和念珠菌血症患者的念珠菌菌株分布没有显著差异。在念珠菌/细菌混合型BSI患者中,分离到25株(61.0%)革兰氏阳性球菌和16株(39.0%)革兰氏阴性杆菌。与念珠菌血症患者相比,念珠菌/细菌混合型BSI患者需要更长的抗真菌治疗时间[12.0(4.0-25.0)天vs 7.0(3.0-13.5)天,P=0.027],但两组30天和90天的粗死亡率没有差异(40.0%vs 32.3%;45.0%vs 36.5%;均P>0.05),念珠菌血症发作时入住ICU,输血,人白蛋白输注,机械通气,利奈唑胺的使用和SOFA评分高与念珠菌/细菌混合型BSI的发生有关(均P<0.05)。多因素分析表明,只有SOFA评分高时才是独立的危险因素(P=0.003)。结论革兰氏阳性球菌是念珠菌/细菌混合型BSI中的主要菌种。与念珠菌血症相比,念珠菌/细菌混合型BSI需要更长的ICU住院时间、更长的住院时间和更长的抗真菌治疗。高SOFA评分是念珠菌/细菌混合型BSI的独立危险因素。关键词:念珠菌血症;细菌血流;混合感染;临床特征;菌株分布;抗真菌易感性;风险因素;临床结果

Objective To study the protective effect of chemokine C-C motif ligand 6 (CCL6) on glucose-oxygen deprivation induced injury in cardiomyocytes and its possible molecular mechanism. Methods Gene expression was analyzed in the public database Gene Expression Omnibus (GEO) database and gene expression of analyzed for myocardial tissue was analyzed gene expression in the sham group and the ischemia-reperfusion group (IR group). Rat H9C2 cardiomyocytes were cultured in vitro, and myocardial cell injury model was established by oxygen glucose deprivation (OGD). Cell viability was detected by MTT assay; apoptosis was determined by Annex V/PI double staining; the expression of related genes was detected by real-time PCR and Western blot. Results Compared with the sham group, transcriptome analysis and real-time PCR showed that the expression of CCL6 in the myocardial tissue of the IR group was significantly decreased (P<0.01). Oxygen glucose deprivation induced a decrease in CCL6 expression levels in H9C2 cardiomyocytes in a time-dependent manner. In addition, oxygen glucose deprivation leads to decreased cell viability and increased apoptosis; while addition of CCL6 promotes cell viability and reduces apoptosis. The lncRNA microarray and real-time PCR showed that CCL6 treatment of cardiomyocytes resulted in a significant decrease in the expression of lncRNA IGF2-AS and further increased the phosphorylation of Akt and GSK-3β. Conclusion CCL6 can inhibit cardiomyocyte injury induced by glucose deprivation, and its molecular mechanism may be related to inhibition of IGF2-AS and enhancement of Akt/GSK-3β signaling pathway.

目的研究趋化因子C-C基序配体6(CCL6)对糖氧剥夺诱导的心肌细胞损伤的保护作用及其可能的分子机制。方法在公共数据库Gene expression Omnibus(GEO)数据库中分析基因表达,并分析假手术组和缺血再灌注组心肌组织的基因表达。体外培养大鼠H9C2心肌细胞,采用氧糖剥夺法建立心肌细胞损伤模型。MTT法检测细胞活力;Annex V/PI双染色法检测细胞凋亡;通过实时PCR和蛋白质印迹检测相关基因的表达。结果与假手术组相比,转录组分析和实时PCR显示IR组心肌组织中CCL6的表达显著降低(P<0.01),缺氧-葡萄糖剥夺诱导H9C2心肌细胞CCL6表达水平下降呈时间依赖性。此外,缺氧-葡萄糖剥夺导致细胞活力降低和细胞凋亡增加;而添加CCL6促进细胞活力并减少细胞凋亡。lncRNA微阵列和实时PCR显示,CCL6处理心肌细胞可显著降低lncRNA IGF2-AS的表达,并进一步增加Akt和GSK-3β的磷酸化。结论CCL6能抑制葡萄糖缺乏引起的心肌细胞损伤,其分子机制可能与抑制IGF2-AS和增强Akt/GSK-3β信号通路有关。关键词:心肌细胞;趋化因子;细胞凋亡

Objective To explore the characteristics and value for predicting prognosis of cytokines in septic children with or without neutropenia. Methods Totally 138 septic children were divided into the neutropenia and non-neutropenia groups according to absolute neutropenic count. Septic children were divided into the shock and non-shock groups according to circulation function and organ perfusion. The levels of C-reactive protein, procalcitonin, cytokines, PRISM-Ⅲ and clinical outcomes were analyzed between the relative groups. Results (1) Totally 138 septic children were recruited, 64 with neutropenia and 74 without neutropenia. The level of PRISM-Ⅲ of the neutropenia group was significantly higher than that of the non-neutropenia group (P=0.048).Mortality showed no significant difference between the two groups, but hospital stay in the neutropenia group was longer than that in the non-neutropenia group. The levels of C-reactive protein, IL-6, and IL-10 ihe neutropenia group were significantly higher than those of the non-neutropenia group (P=0.001; P=0.001; P=0.032). The level of TNF-α in the neutropenia group was significantly lower than that of the non-neutropenia group (P=0.032). (2)Among the 64 septic children with neutropenia, 23 were combined with shock. The PRISM-Ⅲ level of the shock group was significantly higher than that of the non-shock group (P=0.001). The mortality of the shock group (43.5%, 10/23) was significantly higher than the non-shock group (2.4%, 1/41) (P=0.001). C-reactive protein, procalcitonin, IL-6, IL-10 and TNF-α in the shock group elevated obviously than those in the non-shock group (P=0.001; P=0.001; P=0.001; P=0.005; P=0.019). The area under receiver operating characteristic curve was 0.8 for IL-6 (cut-off value 315.38 pg/mL), 0.8 for IL-10 (cut-off value 45.18 pg/mL), and 0.85 for TNF-α (cut-off value 1.95 pg/mL). (3) Among the 74 septic children without neutropenia, 19 were combined with shock. The PRISM-Ⅲ level of the shock group was significantly higher than that of the non-shock group (P=0.022).There was no significant difference of mortality between the two groups (P=0.3). IL-10 level in the shock group elevated obviously than that in the non-shock group (P=0.015).(4) Among the 42 children with sepsis shock, 23 were combined with neutropenia. The PRISM-Ⅲ level of the neutropenia group was significantly higher than that of the non-neutropenia group (P=0.005). There was no significant difference of mortality between the two groups (P=0.29). The levels of C-reactive protein, procalcitonin, IL-6 and IL-10 in the neutropenia group were significantly higher than those in the non-neutropenia group (P=0.001; P=0.001; P=0.001; P=0.035). There was no difference of TNF-α level between the two groups.(5) Among the 96 children without sepsis shock, 41 were combined with neutropenia. No difference of PRISM-Ⅲ level was observed between the neutropenia and non-neutropenia groups. The mortality of the neutropenia group

Objective To investigate the efficacy of venous-arterial extracorporeal membrane oxygenation (VA-ECMO) in the treatment of refractory septic shock in children. Methods From January 2016 to December 2018, the clinical data of children with refractory septic shock (RSS) treated by VA-ECMO in Department of Critical Medicine Affiliated Children's Hospital of Shanghai Jiao Tong University were retrospectively analyzed. The patients with refractory septic shock (RSS) treated by VA-ECMO were compared with those with non-refractory septic shock (NRSS). Results There were 8 cases in the RSS-ECMO group and 6 cases in the NRSS-ECMO group. The sex, age, PRISM score, complication showed no significant difference in the two groups. The median time of ECMO in the RSS-ECMO group was 182 (141, 216) h , and 5 patients were survived and were discharged from the hospital. The blood lactic acid and vasoactive drug index in the RSS-ECMO group was significantly higher than that in the NRSS-ECMO group (P 0.05). After ECMO establishment, the mean invasive arterial pressure increased significantly at 6 h, and lactic acid decreased significantly at 12 h after ECMO support. SCVO2 returned to normal at 24-h ECMO therapy. Conclusions The success rate of VA-ECMO treatment in children with refractory septic shock complicated with MODS is similar to that of children with non-refractory septic shock.

Methods In vivo study: sixty 6-week-old male C57Bl/6 J mice were randomly(random number) divided into three groups evenly, control group, three-day METH treated group and seven-day METH treated group. Mice in control group was given physiological saline through intraperitoneal injection 2 times per day and lasted 7 days. Mice in three days group and seven days group intake methamphetamine at a dose of 15 mg/kg every time through intraperitoneal injection 2 times a day, lasted 3 days and 7 days respectively. The hearts of the mice were then obtained by anatomical method 24 hours after the last intraperitoneal injection of METH, then autophagy related proteins were detected by western blotting. In vitro study: the model was established by H9C2 cells. The cells were divided into two groups, control group (cells were cultured by normal medium) and METH group (cells were cultured by medium includes 900 mmol/mL METH for 24 hours). The expressions change of autophagy related proteins in cells were tested by Western blotting. Additionally, LC3-Ⅱ was tagged by red fluorescent and then the stained cells were visualized under a Zeiss LSM710 confocal microscope. Furthermore, the numbers of autophagosomes in cells were visualized by transmission electron microscopy. Results The expression of p62,Beclin-1and LC3 were significantly increased in METH group when compared with control group (P<0.05). The level of LC3 was significantly increased in METH treated group compared with control group visualized under a Zeiss LSM710 confocal microscope. The numbers of autophagosomes in METH group are more than control group visualized by transmission electron microscopy. Conclusions Autophagy can be induced by METH in myocardial cells.

Objective To investigate the potential therapeutic effect of luteolin on sepsis-induced ALI and the underlying mechanisms. Methods Total of 50 mice were randomly(random number) divided into five groups: a sham control group, a sepsis-induced ALI group, and three sepsis groups pre-treated with 20, 40, and 80 mg/kg body weight luteolin. Mice in the treatment groups were pre-treated with luteolin at the respective oral dose two days before ALI induction. The lungs were isolated for histopathological examinations, and the bronchoalveolar lavage fluid (BALF) was collected for biochemical analyses. Results Luteolin significantly attenuated sepsis-induced ALI. Additionally, luteolin treatment decreased protein and inflammatory cytokine concentration and the number of infiltrated inflammatory cells in BALF compared with that in the non-treated sepsis mice. Pulmonary myeloperoxidase (MPO) activity was lower in the luteolin-pre-treated sepsis groups than in the sepsis group. The mechanism underlying the protective effect of luteolin on sepsis is related to the up-regulation of certain antioxidation genes, including inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), superoxide dismutases (SODs), and heme oxygenase 1 (HO-1), and the reduction of inflammatory responses through blockage of the activation of the nuclear factor (NF)-κB pathway. Conclusions Luteolin pre-treatment inhibits sepsis-induced ALI through its anti-inflammatory and antioxidative activity, suggesting that luteolin may be a potential therapeutic agent for sepsis-induced ALI.

Objective To explore the monitoring of cerebrospinal fluid (CSF) dynamics in a model of brain herniation induced by acute intracranial hypertension in Guangxi Bama-Mini pigs by phase-contrast cine magnetic resonance imaging (PC cine MRI). Methods Femoral artery blood were extracted from 10 pigs, and injected into the frontal and temporal parietal lobe to make a model of brain herniation induced by acute intracranial hypertension. The mean arterial blood pressure (MAP), intracranial pressure (ICP), and cerebral perfusion pressure (CPP) were monitored. Routine T1WI, T2WI, coronal, sagittal and cerebrospinal fluid flow sequence (fast PC cine slice) which positioned on the cervical 3 (C3) vertebral body as the center and perpendicular to the spinal scans were performed on all experimental animals before and after blood injection with 3.0T Magnetic Resonance Imaging. The ICP, MAP, CPP, the absolute values ​​of CSF peak flow velocity and the absolute value of carotid peak flow velocity before and after blood injection were compared. Results The ICP, MAP , CPP, and the absolute value of CSF peak flow velocity before injection of autologous arterial blood were statistically significant as compared with those after blood injection [(6.80±2.044) mmHg vs (52.20±1.619) mmHg, (76.80±7.068) mmHg vs (142.80±12.399) mmHg, (70.00±6.074) mmHg vs (90.50±12.250) mmHg, and the absolute value of CSF peak flow velocity was (243.20±77.671) mm/s vs (201.40±55.482) mm/s, respectively, P 0.05]. Conclusion After the formation of brain herniation induced by acute intracranial hypertension, the CSF flow in the C3 level spinal canal showed a low dynamic change, and the CSF flow velocity waveform was disordered and malformed. The non-invasive measurement of CSF dynamics by PC cine MRI can provide an important basis for the change of CSF dynamics in the model of brain herniation induced by acute intracranial hypertension, and provide a theoretical basis for further research on damage control neurosurgery in the future.

Objective To investigate the effect of interleukin-1β (IL-1β) on the expression of synaptic protein SNAP-25 in the hippocampus in septic neonatal rat induced by systemic lipopolysaccharide (LPS) injection. Methods Sprague-Dawley (SD) rats were randomly divided into two groups: control group and sepsis group. The rat model of sepsis was produced by intraperitoneal injection of 1 mg/kg LPS, and rats in the control group were injected with an equal volume of 0.01 mol/L phosphate buffered saline (PBS). The expression levels of IL-1β and IL-1R1 in the hippocampus at 1, 2 and 3 d, and synaptosomal-associated protein 25 (SNAP-25) at 7, 14 and 24 d after LPS intraperitoneal injection were detected by Western blot. After cultured for 24 h, primary hippocampal neurons were divided into four groups including the control group, IL-1β (40 ng/mL) treatment group, IL-1β (40 ng/mL) + IL-1Ra (40 ng/mL) treatment group, and IL-1Ra (40 ng/mL) treatment group. The effect of IL-1β on SNAP-25 expression in primary hippocampal neuron was determined by Western blot and real-time PCR. The purity of hippocampal neurons were identified by NeuN immunofluorescence staining and the activity of neurons were detected by CCK-8 assay. All data were analyzed by SPSS version 22.0. The data were analyzed by student-t test and Dunnett-t test. The interaction effects were analyzed by factorial ANOVA. Differences were considered to be statistically significant if P< 0.05. Results Compared with the control group, the expressions of IL-1β and IL-1R1 were significantly increased in the hippocampus at 1, 2 and 3 d after intraperitoneal injection of LPS (P 0.05). Conclusions IL-1β may possibly inhibit the expression level of SNAP-25 protein in the hippocampus in the septic rats through its receptor IL-1R1, which would contribute to cognitive dysfunction of septic neonatal rats in later life.

Objective To investigate the clinical characteristics and prognosis of patients with acute aortic dissection (AAD) and hypertension, and explore other related prognostic factors in AAD. Methods The present study enrolled consecutive patients diagnosed with AAD who were admitted to Peking University People's Hospital between January 2000 to December 2015. Patients diagnosed with AAD by CT angiography, aortography or magnetic resonance imaging within 14 days of onset were included. Patients with infectious diseases, haematological diseases, malignancies, autoimmune diseases and patients without clearly clinical diagnosis or incomplete data were excluded. The patients were initially divided into two groups based on their history of hypertension, and their clinical characteristics were compared and analyzed. We further divided AAD patients into survival group and death group according to their in-patient outcomes, and factors related to their prognoses were analyzed. Logistic regression analysis was applied to analyze the independent risk factors related to hospital death in AAD patients with P<0.05 as the significant value. Results The hypertensive group contained 237/346 cases included (68.45%), patients in this group were generally older than their non-hypertensive counterparts, accompanied by increased prevalence of comorbidities (coronary heart diseases or diabetes) and a statistical significant elevated admission blood pressures (systolic and diastolic, P 0.05). Hypertensive patients were less likely to receive surgical treatment compared with those without hypertension(P 0.05). Further logistic regression analysis revealed the presence of hypertension did not independently predict in-hospital mortality of AAD patients. Factors such as age, Stanford classification of the AAD, NLR and platelet counts were found to have independent predictive values for in-hospital mortality (P<0.05). Conclusion AAD patients with hypertension are generally older, have more comorbidities such as coronary heart diseases and diabetes. The presence of hypertension itself is not directly associated with in-hospital mortality in AAD patients, while the Stanford classification, age, NLR and platelet counts are independent risk predictors.

目的探讨急性主动脉夹层(AAD)合并高血压患者的临床特点和预后,探讨影响AAD预后的其他相关因素。方法本研究纳入了2000年1月至2015年12月期间北京大学人民医院连续收治的AAD患者。包括在发病14天内通过CT血管造影、主动脉造影或磁共振成像诊断为AAD的患者。排除患有传染病、血液病、恶性肿瘤、自身免疫性疾病的患者以及没有明确临床诊断或数据不完整的患者。根据患者的高血压病史,将其初步分为两组,并对其临床特征进行比较分析。我们根据住院结果将AAD患者进一步分为生存组和死亡组,并分析与预后相关的因素。应用Logistic回归分析方法分析AAD患者住院死亡的独立危险因素,P<0.05为显著值。结果高血压组为237/346例(68.45%),伴随着合并症(冠心病或糖尿病)的患病率增加和入院血压(收缩压和舒张压,P 0.05)的统计学显著升高。与没有高血压的患者相比,高血压患者接受手术治疗的可能性较小(P 0.05)。进一步的逻辑回归分析显示,高血压的存在没有独立预测AAD患者的住院死亡率。年龄、斯坦福AAD分类、NLR和血小板计数等因素对住院死亡率有独立的预测价值(P<0.05)。结论AAD合并高血压患者年龄较大,合并冠心病、糖尿病等疾病较多。高血压本身的存在与AAD患者的住院死亡率没有直接关系,而斯坦福分类、年龄、NLR和血小板计数是独立的风险预测因素。关键词:高血压;急性主动脉夹层;预后;中性粒细胞与淋巴细胞比率;血小板计数

Objective To explore the effects of immune-enhanced enteral nutrition support on the clinical outcome and nutritional status of patients with acute stress. Methods From December 2014 to August 2015, 120 patients with acute stress were enrolled in this study in the First Affiliated Hospital of Zhengzhou University. The patients were randomly divided into the control group and the experimental group, 60 cases in each group. Besides of medical treatment, the control group received routine enteral nutrition, while the experimental group received immune-enhanced nutrition for 8 days. The main parameters related to nutritional status, immune function, blood glucose, infection control of patients were collected. Results No significance of parameters listed above were observed between patients in the two groups at baseline. After intervention, the levels of prealbumin and lymphocyte counts in the experimental group were higher than those in the control group [(162.5±29.7) mg/L and (136.6±15.1) mg/L, (1.86±0.9) ×109/L and (1.45±0.710) ×109/L, P=0.021 and P=0.012]. The levels of C-reactive protein in the experimental group were lower than those in the control group [ (47.2±22.1) mg/L and (82.6±13.4) mg/L, P=0.043]. Moreover, the level of blood glucose in the experimental group was lower than that in the control group [(5.4±1.7) mmol/L and (6.6±3.5) mmol/L, P=0.009]. The patients in the experimental group had better intestinal tolerance (8.3% vs 25%, P=0.014) but lower mortality (6.7% vs 20%, P=0.032) than those in the control group. Conclusions Immune-enhanced enteral nutrition can reduce level of blood glucose and alleviate inflammatory responses of patients with acute stress, thus improving intestinal tolerance, and reducing mortality.
