ABSTRACT
Autism spectrum disorder is a group of neurodevelopmental disorders that occur in early childhood. The specific pathogenesis is not clear. Abnormal development of neurons and glial cells is a significant feature of patients with autism spectrum disorder. This article reviewed the changes in neurons, astrocyte, microglial cell and oligodendroglia cell in autism spectrum disorder.
ABSTRACT
@#Objective To explore the effect of action observation therapy (AOT) on upper limb function in children with spastic hemiplegic cerebral palsy,and the better program. Methods From March to November,2017,45 children with spastic hemiplegic cerebral palsy were randomly assigned to control group and AOT group.The control group was further divided into group A(n=11)and group B(n=11), and received conventional rehabilitation treatment and scenic-observation therapy, 20 minutes every time for group A,and 30 minutes every time for group B.AOT group was further divided into group C(n=10)and group D (n=11), and received AOT in addition, 20 minutes every time for group C, and 30 minutes every time for group D,five times each week for twelve weeks for all the groups.Before treatment,eight and twelve weeks af-ter treatment, they were assessed with hand grip strength, Upper Extremities Functions Test (UEFT), and Wee Functional Independence Measure(WeeFIM). Results After treatment,the hand grip strength and the score of UEFT were better in group D than in groups B and C(P<0.05),and were better at twelve weeks than at eight weeks(P<0.05).No significant difference was found in the score of WeeFIM among groups after treatment(P>0.05). Conclusion AOT could improve upper limp function in children with spastic hemiplegic cerebral palsy,and it's more ef-fective after more training.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the application effect of Chinese medical clinical pathway for treating attention-deficit hyperactivity disorder (ADHD), and to provide evidence for further improving clinical pathways.</p><p><b>METHODS</b>Totally 270 ADHD children patients were recruited and treated at pediatrics clinics of 9 cooperative hospitals from December 2011 to December 2012. The treatment course for all was 3 months. Scores of attention deficit and hyperactivity rating scale, scores of behavior, Conners index of hyperactivity (CIH), and Chinese medical syndrome scores were compared between before and after treatment. The efficacy difference in various sexes, ages, and disease courses were evaluated by judging standards for Chinese medical syndrome and ADHD.</p><p><b>RESULTS</b>Fifteen children patients who entered clinical pathway dropped out, and the rest 255 completed this trial. Compared with before treatment, total scores of attention deficit and hyperactivity rating scale, scores of attention deficit and hyperactivity rating scale, CIH, and Chinese medical syndrome scores obviously decreased (all P < 0.01). The total effective rate in disease efficacy was 87.8% (224/255 cases), and the total effective rate in Chinese medical syndrome curative effect was 87.5% (223/255 cases). The clinical curative effect was not influenced by age, gender, or course of disease when statistically analyzed from judging standards for Chinese medical syndrome or for disease efficacy.</p><p><b>CONCLUSION</b>Intervention by Chinese medical clinical pathway could improve ADHD patients' symptoms, and its efficacy was not influenced by sex, age, or course of disease.</p>

The aim of this study is to establish an HPLC method for simultaneous determinations of mifepristone and its metabolites, mono-demethylated mifepristone, di-demethylated mifepristone and C-hydroxylated mifepristone in plasma and to evaluate the pharmacokinetic characteristics of mifepristone tablet. Twenty healthy female Chinese subjects were recruited and a series of blood samples were collected before and after 0.25, 0.5, 1.0, 1.5, 2.0, 4.0, 8.0, 12.0, 24.0, 48.0, 72.0 and 96.0 hours administration by a single oral dose of 75 mg mifepristone tablet. Mifepristone and its three metabolites were extracted from plasma using ethyl acetate and determined by high performance liquid chromatography. The main pharmacokinetic parameters of mifepristone and its metabolites, including Cmax, tmax, MRT, t(1/2), V, CL, AUC(0-96 h) and AUC(0-infinity), were calculated by Drug and Statistical Software Version 2.0. The simple, accurate and stable method allows the sensitive determinations of mifepristone and its metabolites in human plasma up to 4 days after oral administration of 75 mg mifepristone tablet and the clinical applications of their pharmacokinetic studies.

Objective To explore the changes of S-100 protein(S-100) levels in blood in newborn rats with bilirubin encephalopathy.Methods The model was established by administered bilirubin intraperitoneally(200 mg/kg) in newborn rats.The blood and brains samples were taken from 8 rats at the sequential time points of 6,12,24,48,72 and 96 h after the model established.Eight normal rats were used as the control.The dynamic changes of S-100 were detected by enzyme linked immunosorbent assay(ELISA) and immunohistochemical technique.Results S-100 significantly increased in blood of bilirubin encephalopathy newborn rats compared with controls(P
ABSTRACT
Objective To observe the dynamic changes of neuron-specific enolase(NSE)mRNA and protein in offspring rats brain tissue with bilirubin encephalopathy and explore the pathological mechanism and its diagnostic value on bilirubin encephalopathy.Methods Seven-day postnatal Wistar rats were used for study.One hundred and twenty rats were divided into 2 groups randomly(control group and experimental group),which were respectively subdivided into 6 groups(6,12,24,48,72,96 h).The rats in control group were intraperitoneally administered physiological saline 0.5 mL,the rats in experimental groups were intraperitoneally administered bilirubin(200 mg/kg).Reverse transcription-polymerase chain reaction was used to analyze the dynamic changes of NSE mRNA expression at 6,12,24,48,72 and 96 h in brain tissue of rats with bilirubin encephalopathy.Immunohistochemistry was used to evaluate NSE protein expression in hippo-campi,cerebral cortex,thalamic and pallidus at different times.Results The expression of NSE mRNA significantly decreased in brain tissue of rats with bilirubin encephalopathy from 6 h to 96 h compared with the control groups.The expression of NSE protein in hippocampi decreased in offspring rats with bilirubin encephalopathy from 6 h to 96 h,but there were no differences compared with the control groups.The expression of NSE protein in cerebral cortex was significantly decreased in rats with bilirubin encephalopathy from 6 h to 96 h,there were significant differences compared with the control group.The expression of NSE protein in thalamic significantly decreased in rats with bilirubin encephalopathy from 6 h to 96 h,but there were significant differences between experimental groups and the control groups at 24 h and 72 h.The expression of NSE protein in pallidus significantly decreased in offspring rats with bilirubin encephalopathy from 6 h to 96 h,and there were significant differences compared with control groups.Conclusions The changing trends of expression of NSE mRNA were identical to those of NSE protein.NSE may reflect the degree of injury of neurogliocyte.It can serve as reliable index to determine bilirubin encephalopathy.
