OBJECTIVE:
To investigate the activation characteristics of microglia (MG) in the rats striatum with MA-induced neurotoxicity.
METHODS:
Male Wistar rats were divided randomly into control group (n=24) and experimental group (n=24). The rats of experimental group were injected intraperitoneally with MA (15 mg/kg x 8 injections, at 12 hours interval). The rats of control group were administrated with saline. The tissues of striatum of two rat groups were harvested at 0.5 d, 1 d, 2 d, 3 d, 4 d, 5 d, 6 d and 7 d post initial administrations of MA or saline. The structure changes were observed by transmission electron microscopy and CD-11b immunohistochemistry. The ratio of activated MG was calculated and statistically analyzed.
RESULTS:
In the control group, the morphological characteristics of the MG showed that the cell bodies were small with slender processes, high electronic density nucleus, and fewer organelles known as the "fork-type". In contrast, the MG in the MA-induced neurotoxicity group displayed larger cell body, shorter cell processes or disappeared, lower electronic density nucleus and rich organelles, resembling "bush-like" or "amoeba-like". The ratio of activated MG in control group was below 0.15 at all timepoints, whereas in the experimental group, the ratio of activated MG increased significantly from day 1 to day 7 (P<0.001).
CONCLUSION
The continuous MA stimulation of the CNS results in prominent MG activation.

Objective To investigate the capability of 99 Tcm?tricine?EDDA/HYNIC?SFSIIHTPILPL ( SP94) as a specific probe for HCC imaging. Methods HYNIC?SP94 peptide was prepared by solid phase synthesis, followed by 99 Tcm labeling with tricine?EDDA as the coligand. After determination of radiochemical purity and stability, cell binding study was carried out by incubating Huh?7 cells with 99 Tcm?tricine?EDDA/HYNIC?SP94 at different specific activities (2.5, 4.0 and 30.0 GBq/μmol). The biodistribution studies and microSPECT/CT imaging were performed in Huh?7 tumor?bearing mice ( study group) and Hela tumor?bear?ing mice ( control group ) . Statistical analysis was by two?sample t test. Results 99 Tcm?tricine?EDDA/HYNIC?SP94 was synthesized with over 95% of labeling yield, which remained stable in saline and FBS up to 12 h. With increasing concentrations of 99 Tcm?tricine?EDDA/HYNIC?SP94, Huh?7 cell binding increased but became gradually saturated. In biodistribution studies, (1.02±0.26) %ID/g of tracer was accumulated in Huh?7 tumors at 0.5 h after injection of 99 Tcm?tricine?EDDA/HYNIC?SP94, higher than that in the HYNIC?SP94 blocking group ((0.34±0.09) %ID/g;t=3.537, P<0.05). Compared to Hela tumors, Huh?7 tumors were clearly visualized by microSPECT/CT, with which better imaging quality could be achieved with higher specific radioactivity. Conclusion 99 Tcm?tricine?EDDA/HYNIC?SP94 could achieve a high labeling effi?ciency and good in vitro stability as a potential diagnostic tracer specifically targeted for HCC.

BACKGROUND: Ulinastatin (UTI) is a urinary trypsin inhibitor extracted and purified from urine of males. This study aimed to explore the effects of UTI on paraquat-induced-oxidative stress in human type II alveolar epithelial cells. METHODS: The human type II alveolar epithelial cel s, A549 cel s, were cultured in vitro. The A549 cel s were treated with different concentrations of paraquat (200, 400, 600, 800, 1000, 1200 μmol/L) and ulinastatin(0, 2000, 4000, 6000, 8000 U/mL) for 24 hours, the cell viability was measured by cell counting kit-8 and the median lethal concentration was selected. In order to establish an in vitro model of paraquat intoxication and to determine the safe dose of ulinastatin, we calculated LD50 using cell counting kit-8 to determine the survival rate of the cells. A549 cells were divided into normal control group, paraquat group and paraquat+ulinastatin group. The levels of malondialdehyde (MDA) and myeloperoxidase (MPO) were detected by biochemistry colorimetry, while the level of reactive oxygen spies (ROS) was detected by DCFH-DA assay. RESULTS: The survival rate of A549 cells treated with different concentrations of paraquat decreased in a concentration-dependent manner. Whereas there was no decrease in the survival rate of cells treated with 0–4000 U/mL ulinastatin. The levels of MDA, MPO, and ROS were significantly higher in the paraquat group than in the normal control group after 24-hour-exposure. And the survival rate of the paraquat+ulinastatin group was higher than that of the paraquat group, but lower than that of the normal control group. The levels of MDA, MPO, and ROS were lower than those of the paraquat group. CONCLUSION: Ulinastatin can alleviate the paraquat-induced A549 cell damage by reducing oxidative stress.

Objective To discuss the methods of selecting different shapes occluder and to evaluate the feasibility,safety and efficacy of them in transcatheter closures of congenital ventricular septal defect (VSD) in children.Methods Transcatheter closures were performed in 226 children with congenital VSD,age ranging from 2 to 14 years(mean 5.62 years) under the guidance of transthoracic echocardiography(TTE) and fluoroscopy.There were 14 patients with intracristal VSD,209 patients with perimembranous VSD and 3 patients with muscular VSD.Left ventriculography and transthoracic echocardiography were performed repeatedly after the procedure to assess the effect of occlusion.The echocardiography and electrocardiography were scheduled before discharge,1,6 and 12 months for the follow-up.Results The occluders were deployed successfully in 211 patients.The successful rate was 93.4%.Thin waist shape occluders,were deployed in 7 patients;equal side shape occluders,were deployed in 191 patients;eccentric shape occluders were deployed in 12 patients,and muscular defect occluders were deployed in 1 patient.There were no complications encountered during or after closure.Conclusions It is very important in transcatheter closure of congenital in children to select different shape occluder according to pathologic characteristics.In general,equal side shape occluder is suita-ble for a large number of defect and it is easy for deployment.In some conditions,the other shape occluder may be necessary.

It is unanimously accepted that stroke is a highly heterogeneous disorder.Different subtypes of ischemic stroke may have different risk factors,clinical features,and prognoses.The aim of this study was to evaluate the risk factors,clinical characteristics,and prognoses of different subtypes of ischemic stroke defined by the Trial of ORG10172 in Acute Stroke Treatment (TOAST) criteria.We prospectively analyzed the data from 530 consecutive patients who were admitted to our hospital with acute ischemic stroke within 7 days of stroke onset during the study period.Standardized data assessment was used and the cause of ischemic stroke was classified according to the TOAST criteria.Patients were followed up till 30 and 90 days after stroke onset.It was found that large-artery atherosclerosis was the most frequent etiology of stroke (37.4%),and showed the highest male preponderance,the highest prevalence of previous transient ischemic attack,and the longest hospital stay among all subtypes.Small artery disease (36.4%) was associated with higher body mass index,higher plasma triglycerides,and lower plasma high-density lipoprotein cholesterol than cardioembolism.Cardioembolism (7.7%),which was particularly common in the elderly (i.e.,individuals aged 65 years and older),showed the highest female preponderance,the highest prevalence of atrial fibrillation,the earliest presentation to hospital after stroke onset,the most severe symptoms on admission,the maximum complications associated with an adverse outcome,and the highest rate of stroke recurrence and mortality.Our results suggest that ischemic stroke should be regarded as a highly heterogeneous disorder.Studies involving risk factors,clinical features,and prognoses of ischemic stroke should differentiate between etiologic stroke subtypes.
