Objective To study the pollution levels,characteristics,causes and related adverse effects of indoor volatile organic compounds(VOCs) on human health after decoration. Methods The concentration of indoor air formaldehyde and TVOC were detected,meanwhile the adverse health effects were investigated by questionnaires. Result The results showed that the houses in which formaldehyde concentration exceeded the national indoor air quality standard occupied 47.1%, and three months later, the rate still was 40%,the highest level was 6.56 times of the standard. While the rate of exceed the national standard of TVOC was 76% within one month and 0% three months later respectively. As far as the concerned subjective syndromes, only the complaint of disgusted smell was significantly different between those who lived in newly decorated rooms and those who lived in the houses which taken as the control. Conclusion Now the pollution level of VOCs caused by decoration is some lower than before,but the pollution of formaldehyde was still pervasive and serious. The causes of pollution lay in artificial board materials used for furniture and decoration. Moreover, the complaints of the discomfort of eyes and upper respiratory tract will increase as people moved in the newly decorated rooms.

This study was designed to determine the effects of the recombinant adeno-associated virus vector containing sense CD151 gene (rAAV-CD151) and antisense CD151 gene (rAAV-antiCD151) on the migration of Tca8113 cell. Functional fragment of CD151 gene was amplified by RT-PCR, and inserted into the vector pAAV in the sense direction and antisense direction, respectively. The rAAV-CD151 and rAAV-antiCD151 were produced and the titers were determined by dot blot. The CD151, at protein level, was detected by Western blot. The Transwell chamber was used to detect the effects of the rAAV-CD151 and rAAV-antiCD151 on the tumor cell migration. The titers of the rAAV-CD151 and rAAV-antiCD151 were 2 x 10(11) pfu/ml and 1.0 x 10(11) pfu/ml, respectively. The expression of CD151 was increased by 108% in the cells transfected with rAAV-CD151 and decreased by 79% in the cells transfected with rAAV-antiCD151, as compared with non-transfected cells, respectively. The number of the migrating cells was significantly increased in the cells transfected with rAAV-CD151 (93.56 +/- 11.59) and decreased in the cells transfected with rAAV-antiCD151 (24.00 +/- 4.36) as compared with non-transfected and rAAV-GFP transfected cells (53.00 +/- 6.56 and 46.00 +/- 7.00, P<0.05). It is an important molecular mechanism of the tumor metastasis that the overexpression of CD151 promotes the migration of the tumor cells. The rAAV-antiCD151 is a novel tool, which can reduce the expression of CD151 and inhibit the migration of the tumor cells, and brings us a new approach of anti-sene gene therapy targeted at CD151 in human carcinoma.

Objeetive To investigate the risk of hemorrhagic transformation (HT) and the outcome as well as its influencing factors at 3 months after thrombolytic therapy in acute ischemic stroke patients with non-valvular atrial fibrillation (NVAF).Methods Consecutive acute ischemic stroke patients with NVAF were enrolled retrospectively.Their demography,vascular risk factors and other clinical data were collected.The modified Rankin Scale (mRS) was used to evaluate the outcome at 3 months after symptom onset.The mRS score ≤ 2 was defined as good outcome,and > 2 was defined as poor outcome.Results A total of 119 acute ischemic stroke patients with NVAF were enrolled,including 63 males (52.9%) and 56 females (47.1%); their mean age was 72.1± 10.0; 45 (37.81%) were treated with recombinant tissue type plasminogen activator (rtPA),55 (46.2%) had a good outcome and 27 (22.7%) combined with HT.Compared with the poor outcome group,the mean age was younger in the good outcome group (P =0.028).The proportions of the patients with ischemic heart disease and the time from onset to treatment > 4.5 h were lower (P <0.05).The baseline systolic blood pressure and diastolic blood pressure,as well as the National Institutes of Health Stroke Scale (NIHSS) score were lower (P <0.05),while the proportion of patients receiving intravenous thrombolysis with rtPA was higher (P =0.019).Multivariate logistic regression analysis showed that the patients with ischemic heart disease (odds ratio [OR] 4.572,95% confidence interval [CI] 1.392-15.014; P =0.012),systolic blood pressure before treatment (OR 1.028,95% CI 1.007-1.049; P =0.009),baseline NIHSS score (OR 1.058,95% CI 1.002-1.117; P =0.042) were the independent risk factors for poor outcome,while intravenous thrombolysis with rtPA (CI 0.264,95% CI 0.102-0.683; P =0.006) was an independent protective factor for poor outcome.The proportions of the baseline systolic blood pressure,fasting blood glucose and NIHSS score,as well as the patients with a history of previous stroke or transient ischemic attack (TIA) in the HT group were significantly higher than those in the non-HT group (all P < 0.05).Multivariate logistic regression analysis showed that the baseline NIHSS score (OR 1.147,95% CI 1.068-1.231; P<0.001),baseline systolic blood pressure (OR 1.951,95% CI 1.921-1.982; P =0.002),and blood glucose level (OR 1.191,95% CI 1.095-1.294; P < 0.001) were the independent risk factors for HT.Compared with the non-thrombolysis group,the mean age of the thrombolysis group was younger (P =0.021),the baseline systolic blood pressure,fasting glucose and NIHSS scores,as well as the proportions of patients with hyperlipidemia,previous stroke or TIA history,and using antihypertensive drugs before admission were higher (all P < 0.05).The proportion of patients with ischemic heart disease were lower (P =0.035),but the proportion of the patients with a good outcome was higher (P =0.019).Conclusions Patients with ischemic heart disease,systolic blood pressure and higher baseline NIHSS score before treatment were the independent risk factors for poor outcome,while intravenous thrombolytic therapy with rtPA was an independent protective factor for poor outcome; the high baseline NIHSS score,baseline systolic blood pressure and glucose level were the independent risk factors for HT.For acute ischemic stroke patients with NVAF,such as no obvious contraindications for thrombolytic therapy,might benefit from intravenous thrombolytic therapy,and it could not increase the risk of HT,but the blood pressure and glucose level of the patients should be controlled appropriately.

AIM: To explore the role of NO in the induction of brain ischemic tolerance (BIT) by observing changes of NOS activity and NO_2-/NO_3- content following a transient cerebral ischemia. METHODS: The rat 4-vessel occluding brain ischemic model was used. 140 male Wistar rats were divided into sham, cerebral ischemic preconditioning (CIP), ischemic insult and CIP+ischemic insult groups. An occlusion of the 4 vessels for 3 min was normally used as CIP, and a relative long one for 10 min was used as ischemic insult. When CIP was followed by ischemic insult, the interval between them was 3 d. The CA1 region of the hippocampus of rats was dissected out at 0 h, 2 h, 16 h, 24 h, 36 h, 72 h and 7 d after the last time of ischemia to assay its NOS activity and NO_2-/NO_3- content. RESULTS: The NOS activity and NO_2-/NO_3- content began to increase at 16 h, peaked at 24 h and decreased to basal level at 36 h of reperfusion after CIP. The duration of the up-regulation of NOS activity and NO_2-/NO_3- content was much shorter than that of BIT, which usually takes place 1-7 d after CIP. The pattern of upregulation of the NOS activity and NO_2-/NO_3- content was similar to the CIP group, but the maximum (24 h) was much more than that in CIP group (P
