Objective To explore the expression of drug transporter organic anion transporting polypeptide2(Oatp2) and P-glycoprotein(P-gp) in brains of chronic epileptic rats induced by lithium-pilocarpine.Methods Chronic epilepsy modles were elicited after status epilepticus(SE) induced by lithium-pilocarpine in adult Wistar rats.The expressions of Oatp2 and P-gp were detected by immuno-histochemistry(SABC) method.Results Positive expression of Oatp2 was predominantly in the plexus epithelial cells and(blood-brain) barrier endothelial cells.Weak staining for Oatp2 was also detected in the neurocyte.In contrast,apparent expression of(P-gp) was seen in brain capillary and neurocyte only.Compared with normal control rats,expression of Oatp2 on the plexus epithelial cells and brain capillary in chronic epileptic rats was significantly decreased(P

Objective To investigate the effects of electro-acupuncture (EA) on remyelination after sciatic nerve was transected in rats, so as to explore the possible mechanism of EA in treatment of peripheral nerve injury. Methods After transection of rat's sciatic nerve, the nerve regeneration chamber was built,then the rats were given EA stimulation at frequencies of 5 Hz and 100 Hz, respectively, and Solochrome Cyanine staining, HE staining of nerve fibers, immunohistochemical staining and semi-quantitative image analysis technique were employed to observe the remyelination of the nerve fibers and S-100 protein expression of Schwann cells. Results EA could significantly promote remyelination of the nerve fibers, elevate S-100 protein expression of Schwann Cells in repairing process of transected sciatic nerve of rats. The therapeutic effect of 5 Hz EA group was better than that of 100 Hz EA group. Conclusion EA is an effective way for the treatment of peripheral nerve injury. It can promote proliferation of Schwann cells and nerve fiber myelination. The therapeutic effects of EA are frequency-depondent.

Objective To investigate the effect of nicergoline on cognitive ability and executive function for patients with vascular cognitive impairment without dementia (VCIND).Methods Totally 68 patients with VCIND were divided into conventional treatment group (33 cases) and nicergoline treatment group (35 cases,nicergoline 10 mg,tid added on basal conventional treatment).All of cases were continuously treated for 12 weeks.Cognitive ability and executive function before and after treatments were evaluated.Results Test scores of immediate free recall of a list of words,the numbers and symbols transformation,the word fluency,clocks and watches painting,and minimental state examination (MMSE) were significantly higher in nicergoline treatment group than in conventional treatment group (P＜0.05).Conclusions Nicergoline may improve attention and memory as well as cognitive ability in patients with vascular cognitive impairment without dementia.

Objective To explore the pathogenesis-related imprinted genes in osteosarcoma and investigate the role of imprinted genes expression in osteosarcoma pathogenesis.Methods The model of malignant transformed immortalized human osteoblastic cells was established and the malignant transformed cells were collected on day 40,55,70,90.The untreated cells passaged from the normal cells on day 90 served as control.After the total RNA extraction,the finally synthesized biotinylated cDNAs were hybridized to CapitalBio Genechip CAP-F0017.2 of the differentially expressed genes.Two genes were chosen at random to further confirm the array results using the SYBR Green real-time PCR in samples of control,day 40 and day 90. Results By an entrance limit of ≥2.0 or ≤0.5,ten imprinted genes which biological functions are mainly related with cell growth/maintenance and signaling transduction were detectable for notablely differential expression,including down-regulated genes of CD81,GRB10,NDN,MEST and up-regulated genes of H19,MKRN3,SLC22A1L,TSSC3,CDKN1C in the malignant transformation of immortalized human osteoblastic cells.The array results were further confirmed by the real-time RT-PCR.Conclusion Ten imprinted genes were detectable for notablely differential expression.Our results will promote our understanding of the molecular mechanisms of imprinted genes in the course of osteosarcoma pathogenesis.

0.05). In hFOB, the expression of P53 was not detected, and that of P63 was weakly positive. The expression of P53 and P63 in HOS transformed by niekel sulfate were higher than that in normal HOS (P

Along with the gradual implementation in legislative work of traditional Chinese medicine,the acupuncture education in Australia has rapidly developed.This paper will examine the history of acupuncture in Australia,laws and regulations of acupuncture education in Australia and the Australian acupuncture education system.It will also demonstrate on how the legislation of traditional Chinese medicine has promoted the development of acupuncture education in Australia.

Objectives To explore the long-term prognosis, treatment (especially dietary treatment) of classic maple syrup urine disease. Methods The complications and dietary treatment were observed by follow-up study of a classic MSUD patient. Results The patient have obvious damage in nervous system. However, reasonable dietary leucine tolerance therapy after the neonatal period can effectively reduce the metabolic crisis and complications. A mutation in BCKDHB gene was detected in the patient by genetic testing. Conclusion It is suggested that dietary restriction and monitoring of branched-chain amino acids are helpful to reduce the development of acute metabolic crisis and complications and improve the quality of life.

Objective To evaluate the rate and types of human papillomavirus (HPV) in vulvar intraepithelial neoplasia (VIN).Methods We detected HPV DNA in 67 lesion tissues collected from 40 VIN patients with PCR based reverse line blot hybridization and DNA sequencing. The PCR using GP5/GP6 primers in HPV L1 region resulted in a 150-bp fragment. When the PCR did not amplify the target DNA,another PCR using SPF1/SPF2 primers was performed to amplify the 65-bp fragment.Results HPV DNA amplified with primers GP5/GP6 was positive in 52.2% (35/67) of the lesions. Of the 32 negative lesions,26 (81.2%) were positive for HPV DNA amplified with SPF1/SPF2 primers. The total positive rate was 91.0% (61/67). Ninety percent of the HPV belonged to high risk types. Sequencing data showed that the genotypes of 31 mono-infection lesions were the same as those of the reverse line blot results,yet the sequences in 4 multi-infection samples could not be determined. Of the 26 SPF PCR products,24 could be sequenced. 80.6% (25/31) patients with multiple lesions displayed the same genotype,suggesting HPV in the different lesions from the same patient was monoclonal.Conclusion The high risk type of HPV is associated with vulvar intraepithelial neoplasia and may play an important role in the development of invasive vulvar carcinoma.
