The study was undertaken to determine whether low dose of endotoxin could induce rat brain damage, and its relation to the metabolism of oxygen free radicals. Male Wistar rats were treated with E. Coli endotoxin intraperitoneally (2 mg/kg body wt). Fourteen hours later, the lipoperoxide level was markedly elevated in animals given endotoxin compared with that in the controls (5.0?1.0 vs 3.9?0.7, P

Objective To examine the localization of neurokinin B receptor (NK3)\|like immunoreactivity (\|LI) in the central nervous system of the mouse. Methods An immunohistochemcial staining method was used. Results NK3 receptor\|LI was localized in somatic and dendritic profiles in the most parts and in neuropil in a few regions of the mouse central nervous system. A large number of neurons with NK3\|LI was seen in the anterior olfactory nuclei, accumbens nucleus, septal area, ventral pallidum, pallidum, caudate putamen, nucleus of the stria terminalis, anterior hypothalamic area, tuber cincreum area, lateral hypothalamic area, perifornical nucleus, supraoptic nucleus, arcuate nucleus, mammillar nuclei, substatia nigra, ventral tegmental area, retrorubral area, superior and inferior colliculus, periaqueductal gray, nucleus of the solitary tract, and superficial layers of the medullary and spinal dorsal horns. The superfical layers of the cerebral cortex, piriform cortex, dorsal hippocampus, amygdal complex, reticular formation of the brainstem contained some neurons with NK3 receptor\|LI. In the ventral hippocampus, median and intralaminar nuclei of the thalamus and interpeduncular nuclei, NKR\|LI was localized in neuropil. Conclusion\ Neurons with NK3 receptor\|LI were widely distributed in the central nervous system. It may be involved in many physiological functions in the central nervous system of the mouse.\;[

OBJECTIVE To explore the early intervention effect in autism spectrum disorders children with dysaudia. METHODS Three cases of child with language barrier were diagnosed with dysaudia by acoustic impedance test, distortion otoacoustic emission (DPOAE) and short sound auditory brainstem response test (ABR). They were diagnosed with autism pectrum disorders through further test. They were matched with hearing aid, and took speech rehabilitation training, followed-up one year to observe the language communication effect. RESULTS After one year of treatment with hearing aid, both CAP and SIR score increased. CONCLUSION Autism spectrum disorders children with dysaudia can get better language exchange by early intervention with hearing aid and speech rehabilitation training.

The aim of this study was to comprehensively investigate the correlations between foliar fungal endophyte communities and effective components accumulations in Salvia miltiorrhiza. Foliar samples of S. miltiorrhiza were collected in 5 different areas. Their fungal endophyte communities and effective component contents were determined by denaturing gradient gel electrophoresis (DGGE) and high performance liquid chromatography (HPLC), respectively. The results showed that, for characteristics of foliar fungal endophyte communities and effective component contents, there were both similarities and differences among the five samples. Correlation analysis of DGGEs' band and 24 effective components revealed a significant correlations (P < 0.01). For examples, 4 bands (15, 18, 23 and 26) were all significantly correlated with the accumulations of caffeic acid, salvianolic acid B, salvianolic acid C and dihydrotanshinone I.

OBJECTIVE:
To explore the differentially expressed gene profile in cervical squamous cell carcinoma tissues with and without pelvic lymph node metastasis by microarray technique and to screen tumor metastasis-related genes.
METHODS:
Cancer tissue samples were collected from 4 cervical squamous cell carcinoma patients with pelvic lymph metastasis and 6 patients without metastasis before the treatment. Differentially expressed gene profile was identified between cervical squamous cell carcinoma tissues with and without pelvic lymph node metastasis by NimbleGen microarray. Fluorescent real-time quantitative PCR was employed to validate the accuracy of the microarray by detecting the expression of genes picked from the differentially expressed gene profile. We screened tumor metastasis-related genes through the gene bank, PUBMED and gene ontology analysis.
RESULTS:
With the application of microarray, 329 genes were identified as markedly differentially expressed genes between cervical squamous cell carcinoma tissues with and without pelvic lymph node metastasis. Real-time PCR was in accordance with microarray. Forty-four genes associated with tumor metastasis were identified from the differentially expressed gene profile.
CONCLUSION
Gene profile in cervical squamous cell carcinoma tissues associated with pelvic lymph node metastasis is preliminarily identified, indicating that lymph node metastasis of cervical squamous cell carcinoma is a process involving numerous genes.

Objective: To investigate mechanism on the restenosis after percutaneous transluminal coronary angioplasty (PTCA) with FSZ (Hirudo, Rhizoma Coptidis, Radix et Rhizoma Rhei, Radix Curcumae, Rhizoma Polygonati Odoroti, etc) by studying the protective effects of FSZ on arrhythmia and injury induced by ischemia and reperfusion.Methods:Rats were randomly divided into four groups and administered orally with FSZ. Left coronary artery ligature was used to form ischemia and reperfusion model. Lipid peroxidation (LPO), superoxide dismutase (SOD), cyclic adenosine monophosphate (cAMP), area of myocardial infarction, myocyte ultrastructural injury and occurrence of arrhymia were investigated.Results: FSZ could improve the changes in ST segment. In rats treated with FSZ, the levels of SOD were elevated while cAMP, LPO, and the specific viscosity of whole blood or plasma and the aggregation of the platelet were lowered, keep to improving the hemorheological changes. It also could antagonize the myocardial damage by myocardial ischemia or reperfusion reduced the area of myocardial infarction. Especially, Fufangshuizhijing Capsule reduced the area of left ventricular (LV) compared with the control group remarkably.Conclusion: FSZ could obviously antagonize arrhythmia and the injury induced by the ischemia and reperfusion, FSZ may scavenge oxygen free radical, regulate the second messenger, remarkably improve the local circulation to reduce the specific viscosity of whole blood of plasma and the aggregation of the platelet in rats, protect mitochondria safeguard the cardiac myocyte to treat PTCA.
