Autism is a pervasive developmental disorder characterized by deficits in socialization, communication, and adaptive functioning. To investigate its neurophysiology, lots of measures have been used. In the past twenty years, due to its evaluation function in the central auditory processing and recognition, auditory event related potential has been implemented in autism more and more generally.

The serum lipids and lipoproteins in 15 type Ⅱ nephrotic syndrome were studied and compared with 20 health controls. The serum TC, TG, LDL-C were significantly increased. There were the inverse correlation between serum TC, TG, LDL-C and albumin and the week positive corre ation between serum lipids, lipoproteins and creatinine. These suggested that there be the wide abnormalities of lipids and lipoproteins in type Ⅱ nephrotic syndrome which may be risk factors of cardiovascular disease and progressive renal diseases.

Objective To explore the clinical significance of procalcitonin(PCT)in guiding the optimizing antimi-crobial treatment strategy in ventilator-associated pneumonia(VAP).Methods Sixty patients receiving mechanism ventilation for ≥48 hours in an intensive care unit between November 2011 and April 2013 were randomly divided into control group (n=29)and trail group (n=31),patients in control group stopped antimicrobial use according to guideline,patients in trail group stopped antimicrobial use according to serum procalcitonin level,duration of anti-microbial use and mechanical ventilation between two groups were compared.Results Days of mechanical ventila-tion,length of ICU stay,mortality rates between two groups were not significantly different(all P >0.05);antimi-crobial days in trail group was significantly less than control group([10.70 ±3.78]d vs [13.93 ±3.03 ]d)(t =4.484;P <0.001).Conclusion Serum procalcitonin level plays an important role in the rational use of antimicrobial agents in patient with VAP.

AIM: It has been proved that transforming growth factor-?1 (TGF-?1) has a close correlation with kidney fibrosis. This study investigated the effects of TGF-?1 on stromal cell-derived factor 1 (SDF-1) in rat renal tubular epithelial cells (NRK52E). METHODS: The experiment was carried out in the Division of Molecular Neurobiology, State Key Laboratory of Biotherapy, Sichuan University from March 2006 to May 2007. ①Rat renal tubular epithelial cells (NRK-52E, Monash Medical Center, Australia) were divided into normal control group, which were not treated with TGF-?1 (Cytola), and experimental group, which were subdivided into time-dependent groups: NRK-52E cells were incubated with TGF-?1 at the same concentration (2 ?g/L) for 6, 12, and 24 hours, and dose-dependent groups: NRK-52E cells were treated with TGF-?1 at different concentrations (2, 5, and 10 ?g/L) for 24 hours. ②The semi-quantitative calculation of SDF-1 protein expression in the cells treated with TGF-?1 at the concentration of 2 ?g/L for different time was accessed by immunocytochemistry to find the best time point. Then the variances of the mRNA and protein expression level in cells treated with TGF-?1 at different concentrations for 24 hours were detected by RT-PCR and Western-Blotting. RESULTS: ①The protein expression level of SDF-1 in NRK-52E cells treated with TGF-?1 for 12 and 24 hours was higher than for 0 hour (P 0.05). This indicated the SDF-1 expression reached a flat stage, and 24 hour was the bets time to study the dose dependence. ②Both the mRNA and protein expression level analyses demonstrated that the expression of SDF-1 in NRK-52E cells treated with 2 ?g/L TGF-?1 for 24 hours was significantly higher than that in normal control group (P

Mechanical ventilation as an important treatment is widely used in clinical practice,the high inci-dence of ventilation lung injury in the course of operating it has been increasingly concerned.The basic mechanism, mechaical stress and high tidal volume machine stimulate lung cells,makes the inflammation in the cells changes,that is,it is from mechanical lung damage to biological injury.With the international and domestic in -depth researches on VILI,the application of control measures,like some medication treatment,ECMO,liquid ventilation have reduced the incidence of VILI to a certain extent,the occurrence mechanism and progress of treatment of VILI are reviewed briefly.

The paper analyzes the problems existing in the architecture of traditional telemedicine based on cloud computing,puts forward a kind of telemedicine architecture that adopts Peer to Peer (P2P) Cloud hybrid network by referring to relevant researches,states the architecture characteristics and operation process,and provides several application cases of telemedicine.

Tryptophan is the essential amino acid in the growth of cell.Indoleamine 2,3-dioxygenase is the rate-limiting enzyme in the catabolism of tryptophan along the kynurenine pathway.Indoleamine 2,3-dioxygenase enzyme mainly promotes tryptophan consumption of local micro-environment,causing tryptophan lack,thus inhibiting proliferation and activation of T cell.Tryptophan-derived catabolites suppress allogeneic T-cell proliferation (kynurenine,3-hydroxykynurenine,and 3-hydroxyanthranilate).Indoleamine 2,3-dioxygenase dendritic cells may interact with regulatory T cells forming an immunomodulatory network to promote immune tolerance induction.Though the immune regulation mechanism of the indoleamine 2,3-dioxygenase-initiated L-tryptophan in transplantation remains unclear,Numerous researches indicate that its role of tolerance induction in transplantation will be significant.

Zinc supplementation can reduce the mean duration,the recurrence rate and mortality of diarrhea.Nonetheless,it has no effect on stool frequency or stool output.Zinc supplementation results in different effort for the difference of the duration of diarrhea,pathogens,zinc type and doses of zinc,and shows no effect in infants younger than 6 months.Using iron as a co-intervention can reduce the effect of zinc,but vitamin A or ORS have a synergistic effect with the meeting.Average baseline zinc levels did not contribute to variations in the effect size.Zinc supplements are unlikely to improve compliance with the treatment for diarrheal disease.Longer course,zinc alone,malnutrition,diarrhea,breast-feeding children are prone to vomiting after oral administration of zinc.

Objective To observe the influence of self-management on health care behavior through health education for patients with hypertension after a self-management model was brought to the communities. Methods There are 252 cases chosen randomly from 546 hypertensive patients in 19 communities to participate in the standard management of hypertension in communities voluntarily. They improve their self-management skills through attending lectures, the guidance of healthy lifestyle and self-management manuals. A scientific self-management methods was established and the support of the society and family was improved. The self-control method was used to analyze this study. Results There are significantly differents (P<0.05 ) in basic health knowledge understanding, self-management skills, and blood pressure control after health education compared with before. Conclusions Patients with health education can improve the self-management level. There are obvious effects on changing the bad lifestyle,improving blood pressure control rate, and decreasing the complication of patients with hypertension.

Objective To explore the characteristics of deficit in action imitation upon objects for the children with autistic spectrum disorder(ASD). Methods Imitative tasks involved objects under the condition of different time after the modelling action ,different action number, different action meaning were used to examine the variations between 12 young children with ASD,and with deaf children(D) matched with the non-verbal IQ and CA( n= 12) ,and children with mental retardation (MR) matched with verbal IQ and CA( n= 12). Results Analyses of repeated ANOVA revealed that: there were significant main effect on the imitation of action involved objects within three subjects(F(2.33) = 10. 138, P＜0.01 ) ;the individuals with ASD achieved lower scores(0.766 ±0.029 ) than the children with MR (0.861 ± 0. 029 ), and the children with deaf significantly ( 0. 949 ± 0. 029). Especially,the autistic imitation deficit was shown on tasks of deferred and meaningless action imitation. Conclusion Children with ASD show deficit on imitation involved objects significantly.
