Objective To evaluate the changes in the expression of DJ-1 protein during myocardial ischemia-reperfusion (I/R) in diabetic rats.Methods Fifty male Sprague-Dawley rats,weighing 220-280 g,were used in this study.Type 1 diabetes mellitus was induced by intraperitoneal streptozotocin 65 mg/kg and confirmed by fasting blood glucose ＞ 16.7 mmol/L.Forty animals with type 1 diabetes mellitus were randomly divided into 3 groups:diabetes group (group D,n =10),diabetic sham operation group (group DS,n =15) and diabetic I/R group (group DIR,n =15).Another 10 non-diabetic rats in which citrate buffer 6 ml/kg was injected intraperitoneally were served as control group (group C).Myocardial I/R was produced by occlusion of the anterior descending branch of left coronary artery for 30 min followed by 120 min reperfusion in group I/R.At 120 min of reperfusion,5 rats were sacrificed and myocardial specimens were c(on)tained for determination of infarct size in groups DS and DIR,and 10 rats were sacrificed and myocardial specimens were obtained for microscopic examination and for determination of cell apoptosis,malondialdehyde (MDA) content,superoxide dismutase (SOD) activity and expression of DJ-1 and phosphatase and tensin homologue (PTEN) protein.Apoptotic index (AI) was calculated.Linear correlation between the expression of DJ-1 protein and MDA content,SOD activity,AI and expression of PTEN protein was analyzed.Results Compared with group DS,the myocardial infract size was significantly increased in group DIR (P ＜ 0.05).Compared with group C,MDA content and AI were significantly increased,SOD activity was decreased,the expression of DJ-1 was down-regulated,and the expression of PTEN protein was up-regulated in groups D,DS and DIR (P ＜ 0.05).Compared with groups D and DS,MDA content and AI were significantly increased,SOD activity was decreased,the expression of DJ-1 was down-regulated,and the expression of PTEN protein was up-regulated in group DIR (P ＜ 0.05).There was no significant difference in the parameters mentioned above between groups D and DS (P ＞ 0.05).There was linear correlation between the expression of DJ-1 protein and MDA content,SOD activity,AI and expression of PTEN protein and the correlation coefficients (r) were-0.734,0.593,-0.818,and-0.812 in turn.Conclusion Down-regulation of DJ-1 protein expression is involved in myocardial I/R injury in diabetic rats via decreasing anti-oxidative stress responses and upregulating PTEN protein expression.

Objective To compare the effects of remifentanil infused at different rates on median effective target plasma concentration (EC50) of propofol inhibiting responses to laryngeal mask airway (LMA) insertion and determine the optimum infusion rate of remifentanil when used for fiberoptic bronchoscopy in pediatric patients.Methods Eighty-four ASA Ⅰ or Ⅱ pediatric patients,aged 7 months-3 years,scheduled for elective fiberoptic bronchoscopy,were randomly assigned into 3 groups (n =28 each):normal saline group (group C),remifentanil infused at 3 ng· kg-1 ·min-1 group (group R1) and remifentanil infused at 5 ng· kg-1 · min-1 group (group R2).Responses to LMA insertion were defined as body movement and/or bucking during insertion.The initial target plasma concentrations of propofol were 5.2,4.8 and 4.4 μg/ml in groups C,R1 and R2,respectively.The target plasma concentration of propofol was determined by up-and-down sequential allocation.Each time the target plasma concentration increased/decreased by 0.2μg/ml.EC50 and 95 ％ confidence interval of propofol blunting responses to LMA insertion were determined by probit method.Results EC50 (95 ％ confidence interval) of propofol was 5.03 (4.92-5.12) μg/ml,4.71 (4.58-4.84) μg/rnl and 4.46 (4.20-4.94) μg/ml in groups C,R1 and R2,respectively.There was no significant difference in EC50 of propofol between groups R1 and C (P ＞ 0.05).EC50 of propofol was significantly lower in group R2 than in groups C and R1 (P ＜ 0.05).Conclusion The infusion rate of remifentanil should not be lower than 5 ng· kg-1· min-1 when combined with propofol in pediatric patients undergoing fiberoptic bronchoscopy.

Objective To evaluate the application of partial cpsA-cpsB serotype prediction system as a serotyping method for streptococcus pneumonia.Methods Ninety-four isolates in this study were provided by Microorganism Research Room of Beijing Pediatric Research Institution,Beijing Children's Hospital Affiliated to Capital Medical University.The quelling test was applied to determine gold standard of serotypes of isolates.Polymerase chain reaction (PCR),sequencing,sequence data management and alignment were implemented previously.Results Eighty-three out of all 94 isolates were serotyped by quelling reaction,and 11 isolates were non-serotype isolates.Among the 83 isolates,67 (80.72％) isolates got positive PCR results and 60 (89.55％)isolates got results consistent with gold standard or containing gold standard.Among 12 isolates belonging to 19F,10 isolates were correctly predicted,and 2 isolates were predicted to be 6A,23F/10A.Among 19 isolates belonging to serotype 19A,1 isolate was predicted to be 35 F/47F,and the other 18 isolates were correctly predicted.Among 10 isolates belonging to serotype 14,9 isolates got results consistent with gold standard,and 1 isolate was predicted to be 19A.All 7 isolates belonging to serotype 6B were predicted to be 6A/6B and 4 isolates belonging to 23F were predicted to be 23F/10A.3 of 11 (27.27％) non-serotype isolates got positive PCR results and were predicted to be 6A/6C,6A/6B,19A.Conclusions Partial cpsA-cpsB sequencing system is a useful method for detecting streptococcus pneumoniae serotypes.

Objective To study miRNA expression differences in ovalbumin(OVA)- induced murine asthma models of mice and mast cells stimulated by inflammatory cytokines stimulation,and to better understand asthma deve-lopment so as to provide potential target for its prevention and treatment. Methods OVA - induced murine asthma models were validated by detecting cells in bronchoalveolar lavage fluid(BALF)and histopathology. And miRNA ex-pression differences in the lung tissues between the model group and the normal control group were detected by real -time polymerose chain reaction PCR . After tumor necrosis factor - α(TNF - α),interleukin 12(IL - 12)stimulation, miRNA expression differences in murine mast cells P815 were detected. Results The number of total cells and eosino-phil cells both increased in BALF of the model group[(12. 8 ± 2. 2)x 107 / L vs(5. 6 ± 2. 5)x 107 / L,t = 4. 760,P ﹤0. 05;(6. 6 ± 1. 9)x 107 / L vs(0. 8 ± 0. 8)x 107 / L,t = 8. 068,P ﹤ 0. 05]. In addition,histopathology showed more inflammatory cell infiltration in the model group than that in the normal control group,indicating that the models were validated. The expression of miRNA - 155 was up - regulated approximately 5. 0 - fold in the lung tissues of the model group(P ﹤ 0. 05),while miRNA - 192 showed no differences compared with the controls. After TNF - α and IL - 12 stimulated P815 mast cells,miRNA - 192 expressions in P815 were expression in P815 was up - regulated approximate-ly 1. 9 - fold and 1. 7 - fold after TNF - α and IL - 12 stimulation,respectively(P ﹤ 0. 05). Conclusions It is conclu-ded that miRNAs are differentially expressed in the presence of OVA - induced murint asthma models and mast cells stimulated by inflammatory cytokines. These differentially expressed miRNAs may regulate the function of mast cells and involved in the pathogenesis of asthma.

Objective To analyze the relationship between biochemical level and severity levels and clinical,duration of disease in patients with Parkinson Disease (PD).Methods 69 patients with PD and 69 healthy persons of similar sex and age were selected in the research.Serum uric acid and lipids levels were examined and compared.Results The serum uric acid,triglycerides,total cholesterol and low-density lipoprotein cholesterol (LDL-C) were (322.48 ± 66.18) μmol/L,(1.22 ± 0.86) mmol/L,(4.70 ± 0.92) mmol/L and (3.00 ± 0.85) mmol/L in control group,and (384.23 ± 88.28) μmol/L、(1.64 ± 0.94) mmol/L、(5.37 ± 1.31) mmol/L、(3.53 ± 1.03) mmol/L in control group.The differences are significant (t =-4.68,P =0.000;t =-2.74,P =0.007;t =-2.74,P =0.007;t =-3.49,P =0.001;t =-3.27,P =0.001).Serum UA concentration and high-density lipoprotein cholesterol (HDL-C),LDL-C were lower in patients with Parkinson's disease in duration of disease more than 3 years than those in duration of disease less than 3 years (t =3.373,P =0.001;t =2.440,P =0.017).The serum UA levels of any stages of PD patients were lower than the control group (P ＜ 0.05) according to Hoehn-Yahr staging.All lipid levels in early and middle stage PD disease patients were lower than those in control group (P ＜ 0.05).Serum UA,total cholesterol and HDL-C in female PD patients were (305.69 ± 54.25) μmol/L,(4.99 ± 0.95) mmol/L,(1.25 ± 0.27) mmol/L,and (339.76 ± 73.40) μmol/L,(4.41 ± 0.81) mmol/L,(1.06 ± 0.19) mmol/L in male patients.The difference is significant (t =2.198,P =0.031;t =-2.721,P =0.008;t =-3.266,P =0.002).Multivariate logistic regression models assessed lower uric acid concentrations is the risk of PD (OR =1.01,95％ CI 1.004 ～ 1.015,P =0.001).Conclusion Biochemical level changed differently in Parkinson disease and uric acid reduction could be a risk factor for PD.

Objective To explore the differences between patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) accompanied with or without community-acquired pneumonia (CAP).Methods We collected 141 patients with COPD who met the admission criteria and had multiple acute exacerbation hospitalization history.Among them,40 patients with AECOPD accompanied with or without acute exacerbation of hospitalization of CAP (group A),38 patients with AECOPD accompanied with acute exacerbation of hospitalization of CAP (group B) and 63 patients with AECOPD but without acute exacerbation of hospitalization of CAP (group C).The demographic differences of age,sex and smoking status were analyzed and compared.The clinical symptoms and blood-related inflammatory indicators of pa tients in group A were analyzed and compared under the acute aggravation of CAP.The number of acute hospitalizations in 12 months before onset and 12 months after discharge were tracked.Results The age,smoking rate,COPD-GOLD classification,dyspnea index,anxiety and depression score in group A were higher than those in group B and C,while the percentage of forced expiratory volume in the first second (FEV1) in predicted value was lower than that in group B and C.The proportion of patients who cooperated or needed long-term home oxygen therapy and drug therapy was higher than that in group B and C,with statistical significance (P ＜ 0.05),but there was no statistical difference in each index between group B and C (P ＞ 0.05).The clinical symptoms of cough,expectoration,fever and other blood-related inflammatory indicators were aggravated in group A when accompanied with CAP.The number of acute hospitalizations in 12 months after discharge of AECOPD without CAP was significantly higher than that of COPD with CAP (P ＜ 0.05),while there was no significant difference in blood gas analysis indicators between the two cases (P ＞ 0.05).The number of hospitalizations in 12 months after discharge,percentage of neutrophils (N)and the level of interleukin (IL)-17 were independent clinical predictors of COPD with CAP.Conclusions Patients with AECOPD accompanied with or without CAP (group A) had poor lung function,worse illness conditions,greater support of home oxygen therapy and drug therapy and poor quality of life.Patients with AECOPD accompanied with CAP had more symptoms and higher levels of inflammatory indicators,but less risk of re-hospitalization in 12 months after cure than AECOPD patients without CAP.The number of hospitalization in 12 month after discharge,the percentage of neutrophils (N),and IL-17 level were helpful in screening the patients with CAP from the AECOPD patients.

Depression is one of the most common mental disorders, which can be accompanied by cognitive symptoms in addition to core symptoms.With the improvement of the awareness of the disease, people pay more attention to the cognitive symptoms of depression. The cognitive impairment of patients not only appears in the onset of the disease, but also persists during the remission of the disease, which has a negative impact on the patients’ social function. Some cognitive assessment tools such as cognitive tests, event-related potential(ERP) and eye movement tracking technology have been used to assess cognitive impairment in patients with depression, which show that there are multidimensional cognitive impairments. Some therapeutic methods such as exercise therapy, repetitive transcranial magnetic stimulation(rTMS) and drug therapy have shown the potential to improve the cognitive function of patients with depression. This article reviews related researches in recent years to explore the cognitive impairment and therapeutic methods of patients with depression.
