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 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

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.

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

OBJECTIVETo investigate the effect of thymosin alpha 1 on cellular immune function in the elderly patients with malignant tumor.

METHODSThirty patients with malignant tumor were injected with thymosin alpha 1 subcutaneously at the dose of 1.6 mg q.d. for the first month and q.o.d. for the following month. The number of T cell subgroups and the activity of NK cell in peripheral blood were detected and the quality of life of the patients were evaluated before treatment and at the end of treatment.

RESULTTreatment of thymosin alpha 1 increased the number of CD4 cells and improved the NK activity, and also improved the quality of life of the elderly patients with malignant tumor. There were no side effects found.

CONCLUSIONThymosin alpha 1 can enhance the cellular immune function of the elderly patients with malignant tumor.

OBJECTIVETo observe the clinical therapeutic effect and side effect of pressure-control ventilation (PCV) on traumatic acute respiratory distress syndrome (ARDS) compared with volume-control ventilation (VCV).

METHODSForty patients with traumatic ARDS were hospitalized in our department from June 1996 to December 2002. Twenty were treated with PCV (PCV group) and 20 with VCV (VCV group). The changes of the peak inflating pressure and the mean pressure of the airway were observed at the very beginning of the mechanical ventilation and the following 12 and 24 hours, respectively. The transcutaneous saturation of oxygen pressure, the pressure of oxygen in artery, the mean blood pressure, the central venous pressure, the heart rate and the incidence of the pressure injury were also monitored before ventilation and 12 hours after ventilation.

RESULTSThe pressure of oxygen in artery, the transcutaneous saturation of oxygen pressure, the heart rate and the respiratory rate in the PCV group were obviously improved after ventilation treatment. The peak inflating pressure, the mean pressure of the airway and the central venous pressure in the PCV group were lower than in the VCV group. The incidence of pressure injury was 0 in the PCV group while 10% in the VCV group.

CONCLUSIONSThe clinical effect of PCV on traumatic ARDS is better and the incidence rate of pressure injury is lower than that of VCV. PCV has minimal effects on the hemodynamics.
