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.

Objective To study the characteristics of perioperative care for patients with Mitral Valve Repair (MVP) received totally robotic surgery without opening chest and provide scientific data for the clinic work. Methods The first 13 cases who received MVP with totally robotic was collected on their individual information and nursing data from their admission to discharge. Results All cases were accomplished successfully without complications. After operation 1 patient occurred Cerbral Infarction and recovery activity of extremity prior to discharge. One patient occurred thrombus of right femoral artery and take the right femoral arteriotomy embolectomy. Conclusions Totally robotic surgery with MVP is a new minimally-invasive procedure. Preoperative education is important to alleviate the patient's misgivings care. In early postoperative course, the amount of drainage should be observed and the pulmonary nursing should be carried out, especially the right lung must be stressed. The early postoperative exercise can reduce the recovery time.

Objective To study adrenomedullin (AM) mRNA and protein expression level in myocardium of autoimmune myocarditis animal models induced by immunization of mice with lactobacillus casei cell wall element(LCWE). Methods Forty-five Balb/c male mice were randomly divided into experimental group (n = 30) and control group (n = 15), which were intraperitoneally injected with LCWE and phosphate buffered solution(PBS) at day 0,3,5 and 10,respectively. Sera and myocardium samples were gained 14,21 and 28 days after the first immunization. AM expression levels were determined by semiquantitative reverse transcriptase-polymerase chain reaction(RT- PCR) and immunchistochemistry,and mycardial histopathological lesions were observed. The anti- myosin antibodies in different stages were examined by an ELISA. Results There were myocardial necrosis or inflammatory infiltration in the experimental group, but myocardial lesions were not found in the control group. Anti - myosin antibodies were detected in sera of experimental mice,but not in control group. Immunchistochemistry findings demonstrated that AM expression level was higher in the experimental group than in the control group( P

OBJECTIVETo explore whether the constructed vector of short haprin in vivo can induce human glioma cell line BT325 to produce RNAi duplexes and reverse the expression of MDR1 gene.

METHODSThree 62nt oligonucleotide fragments (shRNA) were constructed according to GenBank MDR1 sequence and were cloned to the retrovirus-delivered vectors. After transfected these vectors directly into the human malignant glioma BT325 cells by lipofectamine 2000 with enhanced green fluorescence protein (EGFP) co-transfecting, the MDR1 gene silence effects were detected by the changing level of mRNA and P-glycoprotein including real time PCR (RT-PCR), Northern blot and Western blot analysis. To assess the multidrug resistance against adriamycin (ADR) and VCR, cell proliferation assays were performed by cell counting kit-8.

RESULTSThe RNAi plasmid vectors were constructed successfully. RT-PCR showed MDR1 mRNA was significantly reduced (P < 0.05). Northern blot analysis showed that the gene silence became most intense at 48 hours after transfection. Western blot analysis demonstrated that P-gp expression was reduced at different time to 12.9%, 30.3% and 4.8%, respectively. The chemosensitivity assays indicated that the transfected cells showed an enhanced sensitivity to ADR and VCR. Based on the value of IC(50), BT325 cells had significantly increased sensitivity to the drugs.

CONCLUSIONThe sequence specific RNAi can inhibit MDR1 mRNA and P-gp expression in the glioma cell line. It may reverse multidrug resistance phenotype, therefore, may provide promising therapeutic modalities in the treatment of human glioma.

Objective To improve objectivity and accuracy of the diagnosis,prognosis,treatment efficiency and observe the levels of cognitive and intelligent deficits of children with attention deficit hyperactive disorder(ADHD).Methods Event related potentials(ERP)P3 wave test provocated by audition and Wechsler intelligence scale for children(C-WISC) test were detected and compared in 60 children with ADHD(ADHD group) and 60 cases of healthy children(healthy control group).The ERP P3 wave test results between 2 groups of children which had different intelligent balance ability were also compared.Results Compared with the healthy control group,there was a significantly longer latency of P3 wave(P

Objective To observe toxic effect of deoxynivalenol(DON)on articular cartilage and synovium of New Zealand rabbits's knee ioints.Methods Fifteen male rabbits were divided randomly into 3 groups:control, high-dosage,and low-dosage group.In high-dosage and low-dosage group,saline solution of DON was injected with a dose of 0.10 and 0.05 ms/kg every 48 h into ear vein of rabbits.Specimen of articular cartilage and synovium were through pathologY methods,and IL-1β,TNF-α,NO levels were assayed in joint liquid,after 20 days. Results Morphological changes were observed, such as synovium inflammative infiltration, chondrocytes deformation and necrosis under light microscope.The levels of IL-1β,TNF-α and NO had statistical significance in comDarison between 3 grouPs(F=19.396,18.195,22.136,P＜0.05).The levels of IL-1β,TNF-α and NO were significantly higher(all P＜0.05),high-dosage[(0.451±0.091),(0.575±0.122)μg/L;(70.27±11.53)μmol/L] and low-dosage group[(0.295±0.107),(0.387±0.131)μg/L;(45.32±12.24)μmol/L]compared with control ((0.1 13±0.049),(0.138±0.087)μg/L;(23.56±9.35)μmoL/L],and high-dosage compared with low-dosage group Conclusions DON results in articular and synovial impairment,which has the symptom similar to osteoarthritis. DON probably causes osteoarthritis.

Objective To characterize the audiological features in the infants with otitis media with effusion(OME)and to investigate the utility of variety of objective andiometry methods in diagnosis and intervention on OME.Methods Fifry six infants(40 males and 16 females)were investigated,who were referred to our clinic at the General Hospital of Chinese People's Liberation Army by the other hospitals from December 2004 to June 2007 when the infants were diagnosed or highly suspected of OME.The ages at the initial diagnosis ranged from 42 days to three years,with an average of five months.The infants,after receiving the conventional otolaryngological exams,were subjected to the tests of auditory brainstem response (ABR),otoacoustic emission(OAE),tympanometry(226 Hz and 1000 Hz)and behaviors audiometry.Results Among 56 affected infants.87 ears were diagnosed with OME,of which 31 infants were affected bilateral and 25 with monaural.For the 49 infants who received hearing screening at birth.36 infants were referred at the initial screening.For the 52 infants who received repeated screening.all subjects were referred.Six infants without receiving hearing screening came to clinic when their parents observed their kids'hearing impairment.Among the 52 cases(104 ears)who received tympanometry test,20 subjects (28 ears)showed B or C type tympanometry curve.Thirty-nine cases(78 ears)were given tympanometry test at 1000 Hz,of which 38 cases(55 ears)showed abnormal hearing.Among 56 infants(112 ears)with ABR test,49 subjects(74 ears)exhibited prolonged ABR type Ⅰ curve.All 56 infants(112 ears)received OAE test,of which 55 subjects(81 ears)were referred Four infants(8 ears)accepted the behavior test and all of them showed A-B Gap.Conclusions The combined tympanometry test at both 226 Hz and 1000 Hz,ABR latency or threshold test,infant's behavior test and OAE,used jointly,enable characterizing better OME in infants.thus helping early diagnosis of this hearing disorder.
