Lacking of objective referential data resources,current domestic psychotherapeutic practice is mainly based on verbal communications and associated subjective means,which elucidates the limitations to its effectiveness including discrepancies between individual patients and low repeatability.With modern technological advancement,psychotherapeutic devices have been invented to change this situation.This paper gives review of the development in this field,and proposes a practical categorization method.Besides,further development of this area is prospected.

Necrotizing enterocolitis of newborn (NEC) remains a significant cause of morbidity and mortality in neonatal intensive care units.Although many advances have been made in the understanding of this disease,the pathophysiology remains incompletely clear,and treatment is mainly limited to supportive care.In recent years,studies have focussd on the role of the inflammatory mediators,signaling and their impacts on the disease process.Investigators also made some advances in the fields of intestinal proteome and probiotics.Early breasffeeding and probiotics are promoted to prevent and/or amehorate neonatal NEC.In this artical,we reviewed the advances in the above fields for helping to the pathogenesis and treatment of NEC.

Via activating G-protein receptor transduction pathways,nitric oxide (NO),an important signal molecule,has a complex and diverse role which is closely related with activity and gene expression of nitric oxide synthetase (NOS).NO is involved in tumor related events such as cellular proliferation,migration,especially the angiogenic process,and it is closely related with the occurrence and progression of prostate cancer.NO donors and NOS inhibitors have anti-cancer and radio-chemotherapy enhancement roles.

Objective To develop and identify the monoclonal antibodies (McAbs) against Region II~+ motif in circumsporozoite protein of Plasmodium falciparum. Methods BALB/c mice were immunized with 12 peptides within Region Ⅱ~+ in circumsporozoite protein of P. falciparum. Spleen cells isolated from the immunized mice were fused with myeloma cell. After three times screening with ELISA, 3 positive hybridoma cell lines were obtained. Results ELISA test indicated that the McAbs reacted with recombinant circumsporozoite protein fragment containing tandemly repeat region and conserved Region II~+. IFA test showed that the McAbs recognized not only the sporozoites of P. falciparum, but also the sporozoifes of P. yoelii. Conclusion McAbs obtained can probe the Region II~+ motif in circumsporozoite protein of P. falciparum, which might also recognize that of other Plasmodium species.

Objective To isolate CESs by dynabeads coated with the specific antibody of CD146 from peripheral blood and its origin was identified.Methods One mL blood with or without admixed HUVECs was diluted(1∶2) in PBS-0.1% BSA.Anti-CD146-coated Dynabeads were added and incubated for 30mins at(4 ℃).Cells bound to anti-CD146-coupled beads were separated from blood in Dynal MPC and then washed and resuspended in(4 mL) buffer.After 4 additional washes with PBS-0.1% BSA using the magnet,the rosetted cells were flushed from the tube wall with (100 ?L) of PBS-BSA with acridine orange or Giemsa,and counted in a hemocytometer in a inverse phase contrast fluorescence microscope.Results The amount of CECs in healthy adult was 10.5(6～16.5)/mL(n=42).The recovery rate was 91%.Isolated CECs were confirmed by positive expression of vWF and CD31.Conclusion Isolation of CECs from blood by immunomagnetic beads coated with antibody of CD146 is characterized by its accuracy,time-saving,high recovery rate,less contaimination of blood and less damage to CECs.It can be used to quantify CECs and to analyze the functional performance of CECs from patients with vascular injury diseases.

Mitochondrial adenosine triphosphate (ATP) synthase is the key enzyme of mitochondrial oxidative phosphorylation reaction. The down-regulation of the mitochondrial ATP synthase is a hallmark of most human carcinomas, which is the embodiment of the bioenergetic signature of cancer in the performance of the decreased oxidative phosphorylation and increased aerobic glycolysis. Combining with the bioenergetic signature of cancer, studies showed that mitochondrial ATP synthase and multidrug resistance and adverse prognosis of tumor were closely related. Its mechanisms are related to post-transcriptional regulation of the ATP synthase, the hypermethylation of the ATP synthase gene and the inhibitor peptide of the mitochondrial ATP synthase, called ATP synthase inhibitory factor 1 (IF1). In this review, we stress the biological characteristics of mitochondrial ATP synthase and the relationship between ATP synthase and multidrug resistance and prognosis of Malignant tumor, in order to find a new way for tumor therapy.

Objective To investigate the attitude of career in undergraduates of rehabilitation therapy. Methods 41 undergraduate students were investigated with questionnaire. Results 14.6% of the students preferred rehabilitative therapeutist, 53.7% knew little about the profession, 31.7% selected this profession for employment, 22.0% loved rehabilitation work, 41.4% would take rehabilitation work for life.Conclusion It is important for school to help the students understanding the profession of rehabilitative therapeutist correctly.

Objective To investigate the changes of T cells and dendritic cells (DCs) and their related factors in children with immune thrombocytopenia (ITP) before and after therapy,and to analyze their clinical significance.Methods T-cells and DCs subsets were determined by flow cytometry both in 64 children with ITP (ITP group) before and after therapy and the control group.The serum levels of interleukin (IL)-4,interferon-γ (IFN-γ),transforming growth factor beta 1 (TGF-β1),and IL-27 were detected by enzyme linked immunosorbent assay (ELISA).Results Treatments of glucocorticoid or IVIg were effective in 41 cases of 64 ITP children.Compared to the control group,helper T cells (Th),Th/suppressor T cells (Ts),T regulatory cells (Treg),plasmacytoid DC (pDC),pDC/myeloid DC (mDC),and TGF-β1 in ITP patient group before treatment were significantly lower,while IFN-γ and IFN-γ/IL-4 were significantly higher (P ＜0.05).In ITP group,Th,Th/Ts,Treg,pDC,pDC/mDC,TGF-β1,and IL-27 were significantly increased,while IFN-γ and IFN-γ/IL-4 were decreased in children with ITP after therapy and achieved response (P ＜ 0.05).However,there was no significant difference between before and after therapy in ITP children without treatment response (P ＞ 0.05).Conclusions T cells and DCs subsets disorder and abnormal cytokine levels are observed in children with ITP,which can be corrected by immunosuppressive therapy,indicating that Th1 overactivity and the decrease of Treg and pDC both in quantity and function may be related to the pathogenesis of ITP in children.

Objective To investigate the effect of Akt on cardiomyocyte hypertrophy induced by hydrogen peroxide(H2O2).Methods The neonatal rat cardiomyocytes cultured in primary generation were treated with low concentrations of H2O2.The cardiomyocyte hypertrophy was evaluated by the determination of average cell volume and protein content.The effects of Akt inhibitor on cardiomyocyte hypertrophy induced by H2O2 was recorded.Western blot was performed to examine the phosphorylation of Akt induced by H2O2.ResultsH2O2 at 10 or 50 ?mol/L stimulated cardiomyocyte enlargement as measured by cell volume and the protein content per cell.The inhibitor of Akt inhibited the hypertrophic response of cardiomyoctes stimulated by H2O2.H2O2 increased the level of Akt phosphorylation in cardiomyocytes,while that is suppressed by the inhibitors of PI3K(phosphoinositide 3-kinase). Conclusion Akt signaling is involved in cardiomyocyte hypertrophy induced by H2O2.

OBJECTIVE To explore the efficientcy of washing and sterilization methods for the endoscopic cell brush. METHODS The contaminated cell brush with the mixture of Bacillus subtilis var.niger spore and blood was washed by four methods:manually washing,multienzyme plus manually washing,ultrasonic cleaner washing,and multienzyme plus ultrasonic cleaner washing,and then dipped in glutaraldehyde for 5 h or 10 h,fumigated with glutaraldehyde for 5 h,and sterilized with 3M ethylene oxide box.The positive rates of occult blood test(OB test),the cleaning rates of B.subtilis var.niger spore and the sterilization eligibility ratio of four serilization methods were compared. RESULTS The washing method that multienzyme plus ultrasonic cleaner washing could clear effectively the contaminated cell brush that the positive rates of OB test was 0 and the cleaning rates of B.subtilis var.niger spore was 99.90%.The positive rates of OB test and the cleaning rates of B.subtilis var.niger spore of manually washing was 56.67% and 90.87%.Fumigated in 3M ethylene oxide box or dipped in glutaraldehyde for 10 h could kill all the spores,but dipped in glutaraldehyde for 5 h or fumigated with glutaraldehyde for 5 h could not. CONCLUSIONS The mixed contaminated endoscopic cell brush should be washed effectively by multienzyme+ ultrasonic cleaner washing,and should be sterilized by fumigated in ethylene oxide box or dipped in glutaraldehyde for 10 h.
