ObjectiveTo investigate the short-term effect of health education intervention on the recovery of new schizophrenia patients. Methods82 patients were randomly divided into observation group, in which patients accepted routine antipsychotic medication, general nursing and system health education intervention, and control group, in which patients accepted antipsychotic medication and general nursing. Brief psychiatric Rating Scale (BPRS) and Positive And Negative Syndrome Scale (PANSS) were used to assess the effects. ResultsThere was no difference in the score of every factor before intervention (P>0.05), but it became different after intervention (P<0.01 or P<0.05). ConclusionHealth education intervention can improve the effect on schizophrenia.

Objective To investigate the meaning of expression of apoptosis related molecules NFKBp65 and p53 and GPX1-mRNA in patients with Keshan disease(KSD).Methods Sixteen chronic Keshan Disease patients were enrolled in KSD group according to electrocardiogram,chest X ray film and clinical examinations on 15,September in 2009,and 23 healthy people were included in control group from physical examination taken in The Second Affiliated Hospital of Xi'an Jiaotong University.Fresh blood(5 ml)was collected from antecubital vein of all subjects in the fasting state.Total mRNA and protein of blood sample were isolated using Trizol.GPX Assay Kit was used to detect GPX enzyme activity,and GPX1-mRNA expression was determined by SYBR Real-Time PCR.Meanwhile,expression of apoptosis related molecules NFKBp65 and p53 were determined by Western blot.Results GPX enzyme activity decreased significantly in KSD group[(108.61±14.10)U]compared with control group[(122.78±11.89)U,t=2.874,P<0.05],GPX1-mRNA level of KSD group(0.553±0.299)notably KSD group(0.802±0.057)compared with control group[(1.065±0.355),t=6.829,P<0.01].p53 increased in KSD group(1.604±0.191)compared with control group[(1.137±0.186),t=3.033,P<0.05].Conclusiom Decreased GPX1-mRNA expression may result in lower GPX enzyme activity of patients with KSD.Thus oxidative damage increases and cadioeyte apoptosis is activated by activating apoptosis signal pathway.

Objective To study the method of internal boundary parameters identification of middle ear.Method The numerical model is created using CT technology.Based on Matlab tools,the neural network for identifying internal boundary is proposed.Result The uniform pressure of 105 dB is applied at the outside of the tympanic membrane,and the harmonic analysis is calculated on the model to take the training samples.The internal condition parameters are identified using the good neural network.Conclusions The investiga-tion shows that the inverse method reveals a fast convergence and a high degree of accuracy.

Objective To explore the effects of stimulating vagus nerve with pulse current on peripheral blood CD4+T lymphocyte of rats with collagen induced arthritis and its mechanism.Methods To duplicate model rats of experimental arthritis(EA)by intradermal injection of Ⅱtype collagen,divide the rats into 2 groups:vagus nerve stimulation(VNS)group and sham operated group.Rats in VNS group were stimulated at the left cervical vagus nerves for 30 minutes a day with constant square wave,pulse current with intra train of 16 Hz,pulse duration of 1.0 ms,train duration of 10 s,interstimulus interval of 1.5 min and intensities of 3.0 mA.Then flow cytometry and immunofluorescence methods were used to detect the activation of CD4+T lymphocytes(expressing CD71)and the expression of nicotinic acetylcholine receptors alpha 7(nAChR?7)and choline acetyltransferase(ChAT)in peripheral blood CD4+T lymphocytes.Results In VNS group,the expression of nAChR?7 and ChAT were significantly raised in CD4+ T cells at 1st weekend(Pa

To study the possibility of activation of vagus afferent in response to lipopolysaccharide (LPS) through interleukin-1 (IL-1), Wistar rats were randomly divided into LPS group and saline (NS) group. The expression of c-Fos, CD14 and Mac-1 were detected by immunohistochemistry staining. IL-1 bioactivity was determined by L929 cell proliferation. The expression of IL-1R I mRNA was detected by in situ hybridization. Our results showed that there were some c-Fos protein expression positive neurons in the nodose ganglion in LPS group, but no c-Fos protein expression positive neurons in the nodose ganglion in control group. The number of macrophages (M phi) in the connective tissue surrounding the abdominal vagus increased significantly in response to LPS i.p. Forty-five minutes after the application of LPS, the IL-1 bioactivity in the supernatant of M phi was increased. Positive IL-1R mRNA neurons were also observed in the nodose ganglion in the LPS group. The results indicate that vagus afferent is activated in response to LPS and that IL-1 production might be involved in the activation of vagus afferent.

OBJECTIVETo investigate the inhibition effect of curcumin on the proliferation of the human esophageal carcinoma cell line Ec109 and its impact on PEN/PI3K/Akt signaling pathway.

METHODSEsophageal carcinoma Ec109 cells were cultured in vitro conventionally and were treated with curcumin at different concentrations. The cell proliferation level was examined by MIT colorimetry, the ultrastructure of curcumin-treated Ec109 cells were detected with transmission electron microscope (TEM) and cell apoptosis was observed by FCM with AnnexinV-FITC/PI double staining. The protein levels of PTEN, Akt, GSK3P and Caspase 3 of curcumin-treated Ec109 cells were detected by Western blot.

RESULTSMTT test showed that curcumin could inhibit the proliferation of Ec109 cells in a time and concentration-dependent manner. TEM examination indicated that curcumin could induce Ec109 cell apoptosis. FCM detection showed that Ec109 cell apoptotic rate increased significantly with the increase of drug concentration. On the other hand, curcumin could promote the expression of PTEN, GSK3beta and Caspase 3 yet reduce the expression of Akt.

CONCLUSIONCurcumin could obviously up-regulate the expression of PTEN, GSK3beta and Caspase 3, surpress PI3K/Akt signaling pathway and hence inhibit the proliferation of Ec109 cells.
