Objectives To analyze the risk factors associated with infant wheezing in Zhongshan city. Methods A multi-center, large sample of case-control study was applied and the data related to risk factors was collected by questionnaire survey. T test and chi-square test were firstly used for univariate analysis, and then the multivariate stepwise logistic regression was used to analyze the independent risk factors associated with infant wheezing. Results A total of nine factors were found rele-vant to infant wheezing by univariate analysis including parental allergic history, way of birth, respiratory syncytial virus infec-tion, Mycoplasma pneumoniae infection, personal allergic history, like crying, parents have constant disagreements, home near the road, and factory around (P<0.05). Parental allergic history (OR=3.441, 95%CI:1.914-6.186, P<0.001), respiratory syncy-tial virus infection (OR=2.910, 95%CI:1.793-4.723, P<0.001), Mycoplasma pneumoniae infection (OR=2.277,95%CI:1.110-4.667, P=0.025), home near the road (OR=2.036, 95%CI:1.280-3.239, P=0.003) and like crying (OR=1.521, 95%CI:1.049-2.206, P=0.027) were approved to be the independent risk factors of infant wheezing in ZhongShan. Conclusions Nine factors have relationship with infant wheezing, including parental allergic history, respiratory syncytial virus infection, Mycoplasma pneumoniae infection, home near the road, like crying, personal allergic history, and that the former five factors are the indepen-dent risk factors.

Objective To observe the therapeutic effect of multidisciplinary rehabilitation therapy on patients with angina pectoris of coronary heart disease.Methods 86 patients with angina pectoris of coronary heart disease were randomly divided into the rehabilitation group(55 cases)and control group(31 cases).The patients in the rehabilitation group received routine drugs and multidisciplinary rehabilitation(psychotherapy,diet guiding,kinesitherapy,post discharged guiding etc).The patients in the control group received routine drugs for 10～14 days,activities after chest pain dispearance and natural life after discharge.The follow up period was 6 months,recording the changes of cardiac event rate,body mass index,blood lipid(glycerol,cholesterol,low-density lipoprotein).Results The rehabilitation group was significantly superior to that of control group in symptom remission velocity and remission degree(P<0.05).Cardiac event rate of the rehabilitation group was lower than that of the control group significantly within follow up period(P<0.01);body mass index and blood lipid were improve in the two groups,but the rehabilitation group was significantly superior to that of the control group(P<0.05).Conclusion The multidisciplinary rehabilitation therapy can improve clinical symptoms of patients with angina pectoris of coronary heart disease and reduce cardiac event.

Objective To investigate the effects of an enriched environment (EE) on the psychological and behavioral symptoms of senescence and on the level of plasmic adrenocorticotropic hormone (ACTH) and serum corticosteroid (Cor). MethodsTwenty male senescence-prone SAMP8 mice of 3 months old were divided randomly into an enriched environment (EE) group and a standard environment (SE) group.Five male senescence-resistant SAMR1 mice of the same age served as the control group.Behavioral symptoms were assessed after 2 months using autonomic activity and elevated-plus maze (EPM) test performance.Plasma ACTH and serum Cor were detected using radio-immunologic methods. ResultsAverage autonomic activity frequency and EPM open-arm times were significantly lower with the SAMP8 mice than among the control group,and the autonomic activity frequency was significantly higher in the EE group than in the SE group of SAMP8 mice.The average EPM open-arm times of the EE group and the SE were not significantly different.Average ACTH and Cor levels were both significantly lower in the SAMP8 mice,and the level of ACTH was significantly higher in the EE group than in the SE group.There was no significant difference in these groups' average Cor levels. ConclusionsThe SAMP8 mice of 5 months demonstrated significant mental and behavioral abnormalities,as well as down-regulated plasma levels of ACTH and Cor.EE An enhanced environment can reduce behavioral disturbance through up-regulating ACTH.

Objective To analyze the clinical effects of thrombolytic therapy in patients with ischemic in-hos-pital stroke (IHS). Methods The clinical data were collected from patients with ischemic IHS in the last five years. The patients were divided into thrombolysis group and non-thrombolysis group, according to the use of recombinant tissue plasminogen activator (r-tPA) treatment. The clinical outcomes were measured by the modified Rankin scale (mRS) at discharge. Results There were a total of 121 patients in this study. There were 6 patients in thrombolysis group and 115 patients in the non-thrombolysis group, respectively. Six patients (100%) in the thrombolysis group achieved favor-able outcomes (mRS 0~2) at discharge whereas only 42 patients (36.5%) in the non-thrombolysis group achieved fa-vourable outcomes. The rate of favorable outcomes was significantly higher in the thrombolysis group than in the non-thrombolysis group (P<0.05). Conclusions R-tPA thrombolytic therapy can improve the prognosis of patients with ischemic IHS.

Objective To examine the interleukin-27 (IL-27) levels in the serum of the patients with neuromyelitis optica (NMO) and healthy controls (HCs) and explore the correlation of the serum IL-27 level with disease severity.Methods Serum concentrations of IL-27 from 39 patients with NMO and 39 HCs were measured by using enzyme-linked immunosorbent assay (ELISA).Mann-Whitney U test was performed to analyze the difference in the IL-27 levels between the NMO group and the HCs.Spearman's rank correlation analysis was used to analyze the correlations of serum IL-27 levels with clinical parameters (EDSS,spinal cord lesion length,annual relapse rate and antibody titers of AQP-4) of NMO.Results The serum IL-27 levels were significantly lower in NMO group than in HCs (P＜0.001).Serum IL-27 levels were negatively correlated with EDSS,total length of spinal cord lesion identified by MRI at the sampling,and the average relapse rate during two-year follow-up (r=-0.439,P=0.010;r=-0.434,P=0.006;r=-0.451,P=0.031).There was no significant correlation between IL-27 levels and antibody titers of AQP-4 (r=-0.027,P=0.871).Multivariate regression analysis showed that serum IL-27 levels were negatively correlated with EDSS (B=-0.025,P=0.023).Conclusion IL-27 may participate in the pathogenic process of NMO and might be a prognosis marker of the disease.

Objective To investigate the efficacy of treatment and prevention of VitE on vacuous chewing move-ments (VCMs) of haloperidol-induced tardive dyskinesia (TD) rats and serum levels of brain-derived neurotrophic fac-tor ( BDNF) and total antioxidant capacity ( TAC) , and to explore the possible mechanisms.Methods Thirty-two male Sprague-Dawley (SD) rats were randomly divided into TD, P-Vit E, T-Vit E and control group (n=8), receiving to-week treatment with Haloperidol (Hal)+NS, Hal+Vit E (medicated at the baseline), Hal+VitE (medicated at the fifth week) or normal saline (NS), respectively.VCM was evaluated at each week.ELISA and spectrophotometer were used to detect the serum levels of BDNF and TAC, respectively.Results The VCM score of both TD group and T-Vit E group increased at the 2nd weekend, reached the peak at the 5th weekend.VCM score of T-Vit E group declined gradually at the 6th weekend and was significantly lower than that in the TD group [(6.5 ±3.3) vs.(27.9 ±5.8), P<0.001] but was not significantly different from the control group (3.5 ±1.9) (P>0.05) at the 10th weekend.There was no significant difference in VCM score between P-Vit E group and control group for ten weeks(P>0.05).At the 10th weekend, serum BDNF [(6.9 ±1.0) pg/mL] and TAC [(11.9 ±3.2) U/mL] levels of TD group were significantly lower than those of the controls [BDNF (8.6 ±2.5) pg/mL, TAC (18.2 ±5.5) U/mL] and T-Vit E group [BDNF (8.7 ±2.0) pg/mL, (18.6 ±5.9) U/mL] (P<0.01).However, there was no significant difference in the BDNF and TAC levels between TD and P-Vit E groups (P>0.05).Conclusions Vit E may relieve and prevent VCM in TD model rats though alleviation of free radical damage.

Objective To screen stable express A30P a-synuclein PC12 cell as the research object,and to preliminarily investigate the activity of different glycogen systhesis kinase 3β (GSK3β) for the regulation of autophagy pathway causes a-synuclein autophagy level change and its effects on cell growth.Methods The vector of A30P a-synuclein was used to transfect to PC12 cells.G418 was used to screen stable expressed cells.Liposome method was used to transfect GSK3β-expressed plasmid,GSK3β silence plasmid,and blank plasmid into these cell lines,and stable expressed activity of GSK3β cell lines were screened.Western blot was used to detect the expression of GSK3 β after transfection and verify the transfection efficiency.Western blot was used to test groups of cells in LC-3 Ⅱ,Beclin1,and a-synuclein expressions.Methyl thiazolyl tetrazolium (MTF) method was used to detect the change of cell proliferation.Terminal dexynucleotidyl transferase (TdT) mediated dUTP nick end labeling (TUNEL) method was used to detect apoptosis.Results (1) When GSK3β expressed group was compared to GSK3β silence group,blank plasmidgroup,and blank control group,the expressions of LC-3 Ⅱ and Beclin1 were significantly increased (P ＜ 0.05),the expression of a-synuclein was significantly reduced (P ＜ 0.05),the results of MTT and TUNEL showed that the cells were the decrease of apoptosis and increase of cell proliferation,with a statistically significant difference (P ＜ 0.05).(2) When GSK3β silence group was compared to GSK3β express group,blank plasmidgroup,and blank control group,the expressions of LC-3 Ⅱ and Beclin1 were significantly reduced (P ＜ 0.05),the expression of a-synuclein was significantly increased (P ＜ 0.05),the results of MTT and TUNEL showed that the cells were the increase of apoptosis and decrease of cell proliferation,with a statistically significant difference (P ＜0.05).Conclusions (1) Activation of GSK3β activity can improve the level of cell autophagy,enhance the ability of alpha-synuclein degradation,and promote cell survival.(2) Inhibition of GSK3β activity can reduce the level of cell autophagy,weaken the ability of alpha-synucleindegradation,and reduce cell survival.(3) Autophagy is closely related to the pathogenesis of Parkinson's disease (PD).The improvement of the level of autophagy and enhancing of the degradation of asynuclein is a new way of the future treatment of PD.
