OBJECTIVETo investigate the value of serum IgA/C3 ratio in the diagnosis of IgA nephropathy and explore its relationship with the clinicopathological features of the patients.

METHODSSixty-six patients with IgA nephropathy, 111 with other glomerular diseases, and 40 healthy control subjects without kidney disease were tested for serum IgA and C3 levels using CRM470 adjusted standardized immune turbidimetric method, and the IgA/C3 ratio was calculated. According to Oxford and Lee's classification criteria, we analyzed the pathological grades of the renal biopsy samples from patients with IgA nephropathy. The ROC curve was used to assess the value of serum IgA and IgA/C3 ratio in predicting IgA nephropathy.

RESULTSPatients with IgA nephropathy had an elevated serum IgA/C3 ratio than those with other glomerular diseases and the control subjects, with an area under the ROC curve of 0.776. An elevated serum IgA/C3 ratio was not found to significantly correlate with the pathological grade of renal biopsy samples in patients with IgA nephropathy.

CONCLUSIONIn the absence of renal biopsy findings, serum IgA/C3 ratio can help in the diagnosis of IgA nephropathy.

Background:Fenretinide,which is capable of generating reactive oxygen species( ROS ),has emerged as a promising antineoplastic agent based on numerous in vitro and in vivo studies and clinical chemoprevention trials. Preliminary studies showed that fenretinide could induce apoptosis in human hepatocellular carcinoma( HCC)cells in vitro, however,the precise mechanism was not clarified. Aims:To elucidate the effect of ROS on apoptosis of human HCC cells induced by fenretinide and the underlying mechanism. Methods:Human HCC cell line Huh-7 was treated with antioxidant vitamin E,fenretinide or their combination,respectively. ROS in live cells was evaluated by confocal microscopy and flow cytometry;cell viability and apoptosis were assessed by CellTiter-Glo Luminescent Cell Viability Assay Kit and Caspase-Glo3/7 Assay Kit;expression and intracellular localization of nuclear receptor Nur77,as well as expression of stress-induced transcription factor GADD153 were measured by immunofluorescence staining and Western blotting,respectively. Results:Vitamin E pretreatment fully blocked the fenretinide-induced ROS production. In Huh-7 cells pretreated with vitamin E,cell apoptosis induced by fenretinide was significantly reduced(P<0. 05). Furthermore,effect of vitamin E pretreatment was noteworthy on reducing fenretinide-induced GADD153 expression, while no significant impact on fenretinide-induced Nur77 expression and translocation was observed. Conclusions:Elimination of ROS by vitamin E can abrogate the pro-apoptotic effect of fenretinide on Huh-7 cells,which indicates the participation of ROS in fenretinide-induced apoptosis of human HCC cells. Its mechanism might be associated with induction of GADD153 protein expression.

Objective To explore suitable anatomy for teaching methods for international medical students from multiple sources. Methods Thirteen international medical students of 6-year-programme (grade 2011) and 19 Chinese medical students of five-year-programme were taught with Chinese system anatomy(module) textbooks and Chinese-English bilingual textbook(as reference) by three-step bilingual anatomy teaching method , which includes previewing anatomical vocabulary , teaching Chinese and foreign students in the same class. Teaching effect was international tested by scale separating teaching and examing and questionnaire survey. SPSS 10.0 was used to do statistical analysis and t test was used to compare the score of Chinese medical students and international med-ical students. P<0.05 students for statistic difference. Results Average test scores of international and Chinese students in the same class were 86.2 and 88.1 respectively, with no significant difference (P﹥0.05). 92.3%(12/13) international students were satisfied with this teaching method and the same class teaching for Chinese and international students . Conclusions Three-step bilingual anatomy teaching method in the same class may be more suitable for international students from multiple sources and this teaching method is worthy of further study and practice.

Objective To understand the blood pressure variability (BPV) and the influencing factors through ambulatory blood pressure monitoring during hemodialysis (HD) in the end-stage renal disease (ESRD) patients.Method Eighty-one ESRD patients on maintenancing HD for more than three months were enrolled into the study.The patients were with properly dry body weight.The blood pressure was monitored using dynamic blood pressure monitor around the HD.BPV was estimated with the coefficient of variation (CV) and standard deviation (SD) of the systolic blood pressure (SBP-CV,SBP-SD).Patients were divided into two groups according to the mean of SBP-CV:high SBPV group and low SBPV group.The possible influencing factors such as age,dialysis duration,ultrafitration volume,ultrafiltration/body weight,therapy of antihypertensive,electrolyte,nutrition state,metabolic bone disease indexes,inflammatory state and serum lipid state were analyzed and compared between the two groups.And multivariate stepwise regression analysis was made between the SBP-CV,SBP-SD and the above observational parameters.Results The average SBP-CV of the 81 patients was (8.12± 3.16)％,SBP-SD was (11.22±4.55) mm Hg.The proportion of hypertention and hypotention in high SBPV(SBP-CV≥8.12％) group (20.0％,25.7％) was higher than that in the low SBPV(SBP-CV ＜8.12％) group (8.7％,6.5％)(P =0.009).Serum high-sensitivity c-reactive protein (hs-CRP) and alkaline phosphatase (ALP) were higher in high SBPV group than that in the low SBPV group[(7.19± 5.95) mg/L vs (3.35±2.78) mg/L,P =0.001 and (180.31±96.32) U/L vs (98.00±41.19) U/L,P =0.049].Serum creatinine and potassium were higher in the low SBPV group than that in the high SBPV group [(1015.83±276.20) μmol/L vs (893.63±216.61) μmol/L,P =0.034 and (5.27±0.78) mmol/L vs (4.80± 0.23) mmol/L,P =0.005].SBP-SD was positively correlated with hs-CRP (β =0.499,P ＜ 0.01),SBP-CV was positively correlated with hs-CRP and dialysis vintage (β =0.464 and 0.211,P ＜ 0.01 and P ＜ 0.05) by the multivariate stepwise regression analysis.Conclusions The SBP-CV during HD is 8.12％ in ESRD patients.Hypertention and hypotention are more often in the higher SBPV patients.SBPV is closely related to the serum hs-CRP.

Fifty five patients with alcohol induced-mental disorder (study group) and 43 local inhabitants without history of alcohol abuse (control group) were surveyed with family environment scale (FES-CV) and generic quality of life inventory-74 (GQOLI-74). The total score and the scores of all dimensions except material life in GQOLI-74 of study group were significantly lower than those of control group(P ＜0. 05). Compared with control group, the scores in FES of study group were lower for factors of cohesion, expressiveness, active-recreational orientation, moral-religious emphasis and organization in the patient's family, while the scores for conflict and control were higher( P ＜ 0. 05 or P ＜ 0. 01 ). The results indicate that family environment is closely correlated with quality of life in patients with alcohol-induced mental disorder, and family therapy would improve their quality of life.

At present, there are 8 sources of neural stem calls (NSCs), such as the early embryo, umbilical cord blood, brain tissue of adults and bone marrow, which are used for experiments. Four methods are also provided to isolate NSCs, for example, the serial passage and the gene transduction. Most of the hotspots at home and abroad are on the modulation of NSC transplantation in vivo, to make it proliferate and differentiate in hand. Most findings are achieved through experiments on rodents, no matter in vitro or vivo, which indicate that the proliferation and differentiation of NSCs can be affected by a variety of biological factors and drugs. Even more, the effects are multiple according to the factors and drugs of different kinds and the same kind of different concentrations, even the same factor would have different roles in different process of the culture of NSCs. The survival of NSCs during transplantation can also be affected by local microenvironment. Neither the NSC endogenous nor exogenous treatment is efficient. Furthermore, the body also rejects the exogenous NSCs. Taken together, it is tough for us to conclude that a factor does have some effects on the NSCs. Moreover, there are still a series of key problems unveiled clinically, such as how to perfect transplantation and whether to choose exogenous or endogenous NSCa for transplantation.
