Objective To explore whether the glomerular podocytes can be damaged by aristolochic acid. Methods Thirty-two male SD rats were equally divided into the following 2 groups:model group in which the rats received the extract of Aristolochia manshuriensis Kom (AmK) by gavage; control group only received tap water by gavage.24 h urinary protein excretion was measured at the end of the 1st and 4th week,and SDS-PAGE gel electrophoresis was performed to detect the protein in urine.At the end of the 4th week,all the rats were sacrificed and the glomeruli were isolated by laser capture microdissection technique.The mRNA expression of nephrin,podocin,CDA2P,podocalyxin and podoplanin in isolated glomeruli was determined by RT-PCR,and the average width of glomerular foot process was measured by electron microscopy and image analysis. Results At the end of the 4th week,24 h urinary protein excretion in the model group was significantly higher than that in the control group (P＜0.01) and the urinary albumin content in model group was also obviously increased.The average width of glomerular foot process in the model group was significantly larger than that in control group (P＜0.01).The mRNA expressions of nephrin,podocin,CDA2P,podocalyxin and podoplanin in glomeruli were significantly down-regulated in the model group compared with the control group,which decreased by 34％,62％,56％,50％(P＜0.01) and 27％ (P＜0.05),respectively. Conclusions Aristolochic acid can damage the glomerular podocytes,resulting in the down-regulation of nephrin,podocin,CD2AP,podoplanin and podocalyxin mRNA expression, the segmental widening of foot process, and increased urinary protein excretion.

Objective To study the pathogenesis of anemia in chronic aristolochic acid nephmpathy(CAAN) rats. Methods The hemoglobin(Hb)values of sixty-two male SD rats were assayed to determine its normal range.Among them,24 rats with normal Hb value were randomly divided into 2 groups:model group (MG)in which rats received the extract of Aristololochia manshuriensis Kom (AmK) by gavage,and control group (CG) received tap water only by gavage.Body weisht(BW),Hb,24 h urinary protein excretion(UP)and creatinine clearance (Ccr)of 6 rats in each group were measured before administration and at the end of the 8th week, respeetively.then these rats were sacrificed.The relative area of renal interstitial fibrosis was measured by microscopy.The mRNA expression of erythropoietin (EPO)in kidney tissue Was determined by real-time RT-PCR;protein expression of type I collagen(Coll),aminopeptidase P (APP),hypoxia indHeible factor let and 2α(HIF-1α and HIF-2α)in kidney tissue Was examined by immunohistochemistry staining. Results Hb values of normal rats presented normal distribution. The normal Hb was (155.9±16.5) g/L. Rat anemia was diagnosed when Hb was below 123.6 g/L. There was no difference in all the examination results between CG and MG before administration (P>0.05). Compared with CG, the Hb and Cer in MG were significantly decreased [(121.66±15.68) g/L vs (169.00±12.89) g/L, (0.63±0.13) ml/min vs (1.27±0.18) ml/min, P< 0.01], and the UP in MG was significantly increased at the end of the 8th week [(27.04±9.40) mg/d vs (6.11±0.84) mg/d, P<0.01]; the relative areas of fibrosis and Col l in renal interstitium of MG were significantly enlarged [(12.89±2.33)% vs (0.55±0.10)%, (13.92±2.92)% vs (1.32±0.84)%, P<0.01]; the protein expression of APP and the mRNA expression of EPO in the kidney tissue of MG were significantly down-regulated [(0.55±0.23)% vs (3.77±1.06)%, 0.005±0.001 vs 0.032±0.013, P<0.01]; the protein expression of HIF-lα and HIF-2α in the kidney tissue of MG was significantly up-regulated (2.55±0.16 vs 1.12±0.46, 2.33±0.33 vs 1.15±0.27, P<0.01), at the end of the 8th week. Conclusions The pathogenesis of anemia in CAAN may be due to the decreased production of EPO caused by the destruction of peritubular capillary. The compensatory up-regulation of HIF-lα and HIF-2α expression can not prevent the anemia development.

Objective To analyze the causes and pathogens of infectious endophthalmitis in ourhospital.Methods The clinical data and laboratory findings of 282 inpatients with infectiousendophthalmitis were retrospectively reviewed.There were 206 males(73.05%)and 76 females(26.95%)with a mean age of(36.0±11.2)years(range from 2 to 79 years).Except 14 patients who lost theireyeballs as of serious conditions.pathogen examinations of vitreous specimen had been performed for allremaining 268 cases.The clinieal and laboratory data were statistically analyzed by Chi-square and Kappaconsistency tests,when P<0.05 the difference should be considered as statistically significant.ResultsThe 4 major causes of infectious endophthalmitis of those 282 patients included ocular trauma(177cases,62.77%),infectious keratitis(61 cases,21.63%),eye surgery(32 cases,11.35%),andendogenous endophthalmitis(12 cases,4.25%).19.21% of the patients in ocular trauma group was 2-13years old,55.74% of the patients in infectious keratitis group was 14-50 years old,and 60.61% of thepatients in eye surgery group was 51-79 years old.The major pathogens were fungus and staphylococcieach accounted for 30.63% of all cases.Most of the pathogenic bacteria were sensitive to ciprofloxaein(81.81%)and gentamicin(77.92%).Conclusions The major reason of infectious endophthalmitis wasocular trauma,and the major pathogens were fungus and staphylococci.Those findings may help us totreat infectious endophthalmitis patients appropriately.

Objective To understand serological detection results of syphilis among hospitalized patients in a gen-eral hospital,and provide new ideas for further prevention and treatment of syphilis. Methods Clinical data of inpa-tients with abnormal serological detection results for syphilis in a hospital from January 2012 to December 2013 were analyzed. Results A total of 164442 patients were admitted to a hospital from January 2012 to December 2013, 112576 of whom were performed syphilis serological screening,2048 cases were with abnormal results of serologi-cal detection for syphilis. The abnormal serological detection results were mainly in patients of 31~ and 41~ years (39.06% ),followed by patients of 51~,61~ years (34.42% ),and≥71 years (15.63% );unemployed people (34.08% ),farmers(23.05% ),and retirees(19.19% )were the main population with abnormal results. The abnor-mal serological detection results distributed in all 36 departments,the main departments were departments of respir-atory medicine(9.86% ),gynaecology(7.13% ),and cardiovascular internal medicine(6.88% ). Non-marital sex is the main route of transmission(56.79% );the main syphilis serological detection results were both positive for Treponemapallidum particle agglutination (TPPA)assay and rapid plasma reagin (RPR)(46.14% ),as well as TPPA positive and RPR negative (43.31% ). 860 (41.99% )patients were with latent syphilis. Conclusion The current status of patients with abnormal serological detection results of syphilis is not optimistic, mainly concentrated in patients of 31-50 years. It is necessary to strengthen publicity and education on prevention and treatment of syphilis,implement syphilis prevention and treatment policy,intensity syphilis screening,so as to pre-vent the epidemic and spread of syphilis.

Objective:To investigate the molecular mechanism of PDGFC regulated by HuR in breast cancer cells.Methods:Through the software analysises,we first predicted the HuR-binding sites on the PDGFC 3'-UTR in breast cancer cells;An RNA-immunoprecipitation tested the interaction of HuR with the PDGFC mRN after adding PDGFC stimulation;Luciferase experiments tested the HuR-binding sites of PDGFC regulated by HuR through structuring five truncated of PDGFC 3'UTR.Results:We found five HuR-binding sites in the 3'UTR of PDGFC by software prediction;The RNA-immunoprecipitation showed the co-immunoprecipitation of HuR and PDGFC mRN after adding PDGFC stimulation confirming the direct association of HuR with the PDGFC;Luciferase experiments ofPDGFC mRNA 3'UTR showed that PDGFC regulated by the second and fourth HuR-binding sites.Conclusions:This study reveals the molecular mechanism of PDGFC regulated by HuR through binding to PDGFC mRNA 3'UTR in breast cancer cells,and provided rationale for the development of strategies in the clinical diagnosis and treatment for breast cancer.
