Objective To study the distribution of brain dopamine transporter (DAT) in children with autism by single photon emission computed tomography (SPECT). Methods Brain SPECT imaging was performed in 10 autistic children and 10 normal children, and DAT distribution in different functional areas of brain were calculated and compared by semi-quantitative evaluation of tracer uptake. Results There were no differences in tracer uptake between left and right striatum either in autistic children or in normal children (P=0.556, 0.563), while the tracer uptake level in autistic children was significantly higher than that in normal children (P=0.018). Conclusions The striatum dopaminergic neurons are hyperactive in children with autism. SPECT is helpful for the diagnosis of autism.

Objective To evaluate the immediate effect of percutaneous ventricular restoration (PVR) using the PARACHUTE system in ischemic cardiomyopathy patients with apical aneurysm.Methods The study included 25 patients who received PARACHUTE partitioning device (PVD) implantation in the Xiamen Cardiovascular Hospital between January 2015 to December 2016.Invasive left ventricular hemodynamic assessments as well as cardiac output and cardiac output index were analyzed.Results Twenty-five patients [mean age (65.4±11.9) years] suffered from left ventricular aneurysm and heart failure patients after anterior myocardial infarction were enrolled.Ventricular partitioning device implantation was successful in 24/25 (96.0%) patients.PVR was failed in 1 patient due to unable to land the PVD in a satisfactory location.After implantation, a significant increase in cardiac output [(3.83±0.72) L/min vs.(4.85±0.93) L/min, P<0.01] and cardiac index [(2.32±0.74) L/(min·m2) vs.(2.90±0.82) L/(min·m2), P<0.01] was found.Conclusions Our preliminary experience on percutaneous ventricular restoration using PARACHUTE system demonstrates its feasibility and safety with increase in cardiac output and cardiac index immediately following the device implantation.

Objective:To observe the clinical effects of targeted percutanous ozone ablation on lumbar disc herniation (LDH) patients with high intensity zone (HIZ) in lumbar disc annulus fibrosus on MRI T2 weighted imaging.Methods:136 LDH patients with HIZ in lumbar disc annulus fibrosus on MRI T2 were divided into two groups according to therapy methods.In group A,75 patients were injected with 2 ~5 mL of 40 μg/mL mixture of O3 and O2 after targeted percutanous puncturing under the guidance of X-Ray machine with C-type arm.In group B,61 patients were treated with conservative treatment.MacNab score criterion and Oswestry disability index (ODI) were used in assessment of the efficacy.Results:Except 24 patients,all the other cases were followed up for 18 ~ 44 months.At the postoperative 1st,2nd,3rd,6th,9th,12th and 18th month,according to MacNab score criterion,the effective rates were respectively 88.00 %,90.67 %,93.33 %,89.39 %,84.85 %,78.13 % and 73.44 % in group A and respectively 68.85 %,62.30 % 55.74 %,61.82 %,58.12 %,54.17 % and 47.92 % in group B.There were significant differences between two groups at the same time point (P<0.05).At the postoperative 12th and 18th month,ODI was lower in group A,and there was no significant difference between two time points (P>0.05).But it was significant different with that preoperatively and in group B at the same time point (P<0.05).Conclusion:Targeted percutanous ozone ablation is an effective method with stable clinical efficacy in treating LDH with HIZ in lumbar disc annulus fibrosus on MRI T2 weighted imaging.

Objective To discuss the national standard method of"General Test Method in Salt IndustryDetermination of Iodine Ion"and point OUt an incorrect concentration of sodium hypochlorite(NaClO)solution which is not matched with the concentration of oxalic acid solution being used in the national standard method.Methods The iodine ion in the reference salt was determined step by step as stipulated in the method.During the test,the concentration of the NaClO solution was altered from 5.0%to 0.1%in order to screen the suitable ranges of the concentration of NaClO solution.Results 5.0%NaClO solution was used according to the national standard method,which led to a significant deviation up to 700 ms/kg.The relative errors of the standard iodized salt determination were respectively 2312.0%,185.0%,4.0%,3.3%,-0.6%,-3.0%,-3.3%with different concentration NaClO(5.0%,3.0%,2.5%,1.0%,0.3%,0.2%,0.1%).Conclusion Under the circumstance that the concentration of the oxalic acid solution remains the same.the concentration of NaClO solution must be revised into 0.3%~2.5%in the national standard method to decrease testing errors.

AIM:To explore the preventing effect of citalopram on neuro-cell apoptosis caused by long-term stress in CA1 and CA3 region of hippocampus.METHODS:Forty male Sprague Dawley(SD)rats were randomly divided into five groups including blank group,control group(the control group was filled the stomade by 0.9% saline)and three experimental groups(intragastric administration of citalopram hydrobromide at doses of 8 mg?kg-1?d-1,4 mg?kg-1?d-1,1 mg?kg-1?d-1,respectively).Rat stress model was made by compulsory swimming everyday for 4 weeks.Cell apoptosis in CA1 and CA3 region of hippocampus was observed by HE staining method.Apoptotic cell numbers and integral optical density in CA1 and CA3 region were tested and analyzed by terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling(TUNEL)method and Norton Internet Security BR(NIS BR)software.t-test was applied to compare apoptosis cell numbers and integral optical density.RESULTS:Control rats showed more static time and less struggling times.Conversely,static time was shorter and rats spent more time after exhaustive exercise,and more struggling times in the experimental group.Rats in control group showed more positive cells in CA1 and CA3 regions and higher integral optical density in CA3 region than those in blank group.Rats in experimental groups showed fewer positive cells in CA1 and CA3 regions.Rats in experimental group 1 and group 3 showed higher integral optical density in CA1 and CA3 regions than that in control group.CONCLUSION:Long-term stress might cause neuro-cell apoptosis in CA1 and CA3 region of hippocampus.Citalopram might have prophylactic effect on apoptosis caused by long-term stress in CA1 and CA3 region,and the prophylactic effect might not be influenced by citalopram.Our study suggests that the treatment mechanism of citalopram in neural and mental illness by long-term stress may involve in a major role by antagonizing neuronal apoptosis in both the CA1 and CA3.
