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.

The term "a green hospital", meaning "a safe, dependable and harmless hospital", epitomizes the harmony between the hospital's intrinsic quality and extrinsic surroundings. Thus, the construction of a green hospital possesses rich connotations, viz. powerful guarantee, of medical safety, dependable guarantee of quality, delivery of civilized services and harmonious doctor-patient relationship, and comfortable and humanized surroundings for medical care. It is imperative to formulate comprehensive assessment standards for green hospitals or incorporate such standards into the conditions for hospital appraisal so as to render the idea of green hospital a target of hospital development.

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

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.

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.

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.

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.

Tryptophan 2,3-dioxygenase (TDO)is the rate-limiting enzyme in the catabolism of Trp along the kynurenine pathway.Trp is mainly catabilized by the TDO in the liver,which could not only regulate the concentration of the Trp and suppress the T cells proliferation,but also participate in antibacterial action and inflammatory response.The metabolin kynurenines as an endogenous ligand of the AhR receptor,the TDO enzymes,Kyn and AhR form the TDO-Kyn-AhR pathway have effects of regulatory the growth of tumor.With the research of the mechanism of immune regulation goes futher,it is expected to be a promising prospect in cancer therapy and the immune tolerance of transplantation.We reviewed in the article,which summarized the TDO mediated catabolism of Trp and immunomodulatory effect.

CTGF, a member of the CCN family of immediate early genes, is a recently discovered profibrotic growth factor, which is involved in many pathophysiologic procedures. CTGF acts as a downstream effector of TGF-? acting on interstitial cells to enhance the progression of fibrotic renal diseases. It has been shown that CTGF gene expression can be induced or blocked by some kinds of cytokine and drugs. It is an interesting candidate target for future intervention strategies of renal interstitial fibrosis. [
