To investigate the pathogenic mechanism of interleukin 6(IL-6) in the tubulointerstitial lesions of patients with active lupus nephritis(LN). Methods Uninary IL-6 from 42 active LN cases and the renal tissues sections from 15 of them were examined by performing ELISA and in situ hybridization with IL-6 cDNA probe labelled by digoxingenin respectively. Results In 36/42 (85.7%) of active LN patients, uninary IL-6 content was higher than or equal to 5 pg/mg ,cr, while no one case did in normal controls. Uninary IL-6 content was highly correlated with the uninary ft-m and NAG excretion respectively. In normal tubules and interstitium, IL-6 mRNA was undetectable. For all sections from 15 active cases, IL-6 mRNA was found in tubular and interstitial cells, and the distribution correlated with the extent of tubulointerstitial lesions. Conclusion IL-6 is probably involved in tubulointerstitial lesions of patients with active lupus nephritis.

The relationship of the nose tip position and the skull figures which were measured from the lateral craniographs in 49 ladies of 17～19 age living in Shenyang was studied. The figures measured on craniographs were analyzed by multiple stepwise regression analysis on IBM-PC/XT computer, and the regressoin equations for estimating the nose tip position of female in Shenyang were obtained. Cases in which the errors were within 2 mm were 71.43 to 77. 55 percent.

Objective To investigate the influence of mental intervention on the self-image of breast cancer patients.Methods Fifty patients with breast cancer who were hospitalized in our hospital from January to September,2015 were enrolled as the control group in the study,where routine nursing intervention,health education on disease related knowledge and psychological nursing were carried out.During October 2015 to June 2016,50 patients with breast cancer were enrolled as the observation group,where psychological awareness intervention was carried out apart from the routine nursing intervention.The self-image level of breast cancer patients from the two groups was evaluated by self-image questionnaire for breast cancer patients (BIBCQ).Result After intervention,the scores on self-image in the observation group were significantly higher than those in the control group (P＜0.05).Conclusion Mental intervention can improve the self-image of breast cancer patients and help improve their quality of life.

Objective This study was carried out to reveal the photocatalytic degradation characteristics of Bisphenol A,a representative endocrine disruptor,with immobilized nanometer TiO2 catalyst supported on fiberglass net.Methods The effects of photolysis under black light lamp and cold cathode low-pressure mercury lamp,and initial concentration(0.98-6.23 mg/L) on the degradation of bisphenol A(BPA) was explored by photoreactor in laboratory.Photocatalytic mineralization and intermediates under different irradiations was also investigated.Results It was found that the reaction kinetics was first order with respect to BPA concentration,and the apparent kinetic constants decreased with the increase of initial concentration.Photodecomposition of BPA under black light lamp irradiation was caused by not photolysis but photocatalysis,while that under cold cathode low-pressure mercury lamp was caused by the synergistic effect of photolysis as well as photocatalysis.Further studies showed that photocatalytic mineralization of BPA differed greatly under those different irradiations.1,4-benzoquinone,p-dihydroxybenzene,methyl p-hydroxybenzoate,D-hydroxyacetophehone,1-(4-hydroxyphenyl)-1-propanone,1-(4-hydroxyphenyl)-vinyl alcohol were identified as intermediates under black light lamp,and 3-hydroxyl-3-crotonic acid,4-hydroxybenzaldehyde,D-hydroxyacetophehone,2-acetyl-3-methoxyl-5,8-dihydroxy-1,4-naphthoquinone,3,4-di-(4-hydroxyphenyl)hexane were found under cold cathode low-pressure mercury lamp.Conclusion The differences of photocatalytic mineralization under different illumination are attributed to the molecule structure with two benzene-rings.

[Objective]To explore effect of polypeptides from chlamys farreri(PCF) on human umbilical cord blood cells(HUCBCs) differentiation in vitro,the effects of the extract on protein tyrosine kinase(PTKs) was studied in vitro.[Method]Getting human umbilical cord blood cells and cultured with the PCF at dilution concentrations of 1:1600,1:3200,1:6400,1:12800 nerve growth factor(NGF) was used as positive control and DMEM as negative one.After 48,72,96 h,the HUCBCs was cultured and the activity of protein tyrosine kinase(PTK) was examined by ATP in corporation test using PtK assay system.[Result]HUCBCs in the negative control group had no PTK activity,but that of positive control group was detected significantly.The PTK activity in extract of polypeptides from chlamys farreri groups increased at 48h(P

Objective To evaluate the effect of preoperative intramuscular injection of of dextromethorphan in three dosages on fentanyl consumption in postoperative PCA in order to optimize its pre-emptive analgesia dose. Methods 80 ASA Ⅰ-Ⅱ patients underwent spine operations under general anesthesia were randomly divided into four groups, who respectively received intramuscular dextromethorphan 10mg (DM10 group), 20mg (DM20 group), 40mg (DM40 group), or normal saline (CON group) respectively. The PCA fentanyl consumption as well as VAS pain scores were observed 4h, 24h, and 48h after the operation. Results Although there was no significant differences in pain VAS score between the four groups, the fentanyl consumption was significantly lower in groups DM20 and DM40 compared with group CON and DM10. However, there was no significant difference between group DM20 and group DM40. Conclusion Preoperative IM dextromethorphan shows a dose-dependant fentanyl spare effect on postoperative PCA, and a dose of 20mg seems to be optimal for preoperative use.

Traditional sequences of magnetic resonance imaging (MRI) such as T1-weighed imaging, T2-weighed imaging, and fluid-attenuated inversion recovery (FLAIR) imaging can sensitively detect the subacute and chronic intracranial hemorrhage; gradient echo sequence can detect various stages of intracranial hemorrhage, but there is no correlation between the signal intensity of the hematoma and the time of the presence of hematoma. Diffusion-weighted imaging and apparent diffusion coefficient may provide more information about the center and surrounding areas of hematoma, as well as the hemorrhagic tendency after infarction.

AIM: To study the therapeutical effects of salvianolic acid B (Sal B) on myocardial infarction(MI) in dogs. METHODS : The models of myocardial infarction were produced by ligation of the left anterior descending (LAD) coronary artery in the anaesthetized dogs. The extent of myocardial ischemia was detected by epicardial-electrocardiogram and the extent of infarction was determhled by N-BT staining method. The parameter of lactate dehydrogenase was determined in the serums of dogs. RESULTS : It was indicated that the adminstration of Sal B(1、3 and 10mg/kg) by the way of intravenous injection reduced the extent of myocardial infarction (N-ST) ( P

Objective To investigate the expression of heat shock protein 70(HSP70) and c-fos,the presence of apoptosis and the neuroprotective effects of Cudrania tricuspidata root extrate(Ecr) after focal cerebral ischemic reperfusion in rats.Methods Models of middle cerebral artery occlusion(MCAO) were used in this study.The rats in Ecr pretreated ischemia reperfusion(IR) group were fed with Ecr(2 ml tid) for 5 days before MCAO.The brain specimen were took at different reperfusion times: 1 h,6 h,12 h,24 h,3 d and 7 d after recirculation.Then immunohistochemistry,insitu hybridization,terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL) were used to detect the expression of HSP70,c-fos gene and cell apoptosis in the brains.Positive results were semiquantitatively analyzed.Results IR could induce the expression of HSP70 and c-fos.HSP70 was detected at 6 h following reperfusion and peaked at 24 h both in cortical and basal ganglia regions.c-fos was markedly expressed at 1 h and the level peaked at 6 h in the ischemic hemispheres,and then reduced gradually.The TUNEL positive cells were markedly observed at 6 h.After treatment with Ecr,the positive reaction cells both of HSP70 and c-fos were significantly increased(all(P
