Objective To investigate the relevance of the clinical score and pathology score and assess two scoring system including the British Islet Lupus Assessment Group2004 (BILAG2004) and systemic lupus erythematosus disease activity index 2000 (SLEI)AI2000) by analyzing the biopsy results and related laboratory tests on lupus nephritis (LN). Methods Retrospective analyzed 59 cases of patients with renal biopsy. All biopsied tissues were scored based on the to ISN/RPS2003 lupus nephritis pathological typing standards. Meanwhile, respective index (AI), chronic Index (CI) and tubulointerstitial lesions (TIL) score were used to evaluate the activities of lupus nephritis and SLEDAI2000 and BILAG2004 were used to evaluate the clinical disease activity. The adssociation between pathological changes and disease activities was assessed. Results ①According to ISN/RPS2003 pathological type standard, among these 59 patients, type Ⅳ was the most common type,which accounted for 44.07 percent of all biopsied tissues. ② For those patients. With LN typeⅡ,Ⅲ Ⅳ, their SLEDAI2000 score and BILAG2004 renal biopsy AI was positively correlated (00.05). Conclusion BILAG2004 score and SLEDAI2000 scoring system can be used to assess the disease pathology activity of patients with lupus nephritis. The study has found that BILAG2004 scoring system is superior to SLEDAI2000 score system for the assessment of LN patients on pathological activities, especially for with severe LN patients. As a non-invasive method of assessment, BILAG2004 score system is better than SLEDAI2000 score system in guiding clinical treatment.

Objective To examine the effects of different compositions of metabolic syndrome [Overweight and (or) obesity, hyperglycemia, hypertension, dyslipidemia] on chronic kidney disease. Methods A total of 1552 health data were collected from the survey of chronic kidney diseases among Uygur adults in Moyu country in Xinjiang Uygur Autonomous Region and the relationship between metabolic syndrome and chronic kidney disease was analyzed by using SPSS 15.0 software package. Results Before and after adjusting of age and gender, the prevalence of metabolic syndrome was 14.18% and 14.45% (95% CI 14.30%?14.60%). The prevalence of albuminuria (7.27% vs 3.83%, χ2=5.42, P=0.02), reduced estimated glomerular filtration rate (9.55% vs 3.45%, χ2=16.96, P=0.00) and chronic kidney disease(13.64% vs 6.76%, χ2=12.52, P =0.00) increased in residents diagnosed as metabolic syndrome than those without metabolic syndrome. The prevalence of chronic kidney disease increased with the increasing number of metabolic syndrome elements. Conclusions The prevalence of chronic kidney disease is associated with the accumulation of metabolic syndrome compositions. Early intervention on metabolic risk factors may reduce the risk of chronic kidney disease.

Objective To investigate the scintigraphic features of neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) and to explore the clinical significance of 99Tcm-EHIDA hepatobiliary scintigraphy.Methods Hepatobiliary scintigraphy with 99Tcm-EHIDA was performed in 28 genetic confirmed NICCD cases (16 males,12 females,1-8 months).Normal dynamics (i.e.,time-activity curve) of the tracer in heart,liver and kidneys was defined as normal hepatic uptake function.Decreased liver uptake of the tracer and/or prolonged heart and kidneys radioactivity retention was defined as impaired hepatic uptake function.Normal or delayed biliary excretion was defined as radioactivity appearing in the bowel within 60 min or after 60 min.Occluded biliary excretion was defined as absent bowel radioactivity within 24 h.The characteristics of hepatobiliary scintigraphy and their relationship with levels of serum total bilirubin (TB),direct bilirubin(DB),ALT,total bile acid (TBA) were retrospectively analyzed.Statistical analysis was performed using Kruskal-Wallis rank sum test.Results Of 28 NICCD patients,20 showed normal uptake while 8 had impaired hepatic uptake.Ten of twenty patients with normal uptake function showed normal biliary excretion and the others showed delayed biliary excretion.Four of eight cases who presented impaired hepatic uptake function were with delayed biliary and the rest displayed biliary excretion occlusion.Compared with the patients with normal hepatic uptake function,patients with impaired hepatic uptake had significantly higher levels of TB and DB (TB:183.6(128.7-280.9) mmol/L vs 105.5(80.0-141.7) mmol/L,Z=-2.25;DB:135.6 (95.7-212.6) mmol/L vs 73.1(53.9-97.9) mmol/L,Z=-2.73; both P＜0.05).Compared with the cases with normal biliary excretion function,patients with delayed biliary excretion had significantly higher levels of TB,DB and TBA (TB:137.5 (122.0-170.9) mmol/L vs 81.7(65.7-93.5) mmol/L,Z=-3.92;DB:96.5 (81.1-108.0) mrrol/L vs 54.1(45.3-72.6) mmol/L,Z=-3.74; TBA:245.6(183.9-299.2) mmol/L vs 136.0(73.5-163.2) mmol/L,Z=-2.57; all P＜0.05).The levels of TB (262.0(152.1-542.8) mmol/L) and DB (192.7(118.1-407.2) mmol/L; both Z=-2.82; both P＜0.05) were the highest in patients with occluded biliary excretion.Compared with the patients with delayed excretion,the occluded excretion subgroup had significantly higher levels of ALT (71.5 (48.5-144.8) U/L vs 20.0(16.5-27.7) U/L,Z=-2.66,P＜0.05).Conclusion 99Tcm-EHIDA hepatobiliary scintigraphy may evaluate hepatic uptake and excretion function of the NICCD infants.When the hepatic uptake is remarkably decreased,the occluded biliary excretion can be shown.

Objective To observe the effects of action observation therapy based on mirror neuron theory on upper-extremity motor function and performance in activities of daily living(ADL) after stroke.Methods Eightyone stroke patients were randomly assigned to an observational group (41 cases) or a control group (40cases).Both groups received conventional rehabilitation,and the observational group also received action observation therapy for 16 weeks,10 times per week.Upper-extremity motor function and ADL performance were assessed before treatment using the Fugl-Meyer assessment (FMA) and the Barthel index (BI) and then again after 4,8 and 16 weeks of treatment.Results The average FMA scores and BI scores in the observational group at the 4th week (32.50 ± 9.32 and 67.41 ± 16.81),the 8th week (36.35 ± 8.32 and 78.74 ± 15.63) and the 16 th week (41.32 ± 13.45 and 93.85 ± 13.45) had increased significantly compared with the pre-treatment assessment and were significantly better than at the same time point for the control group (P ＜ 0.05).Conclusion Action observation therapy based on mirror neuron theory can promote the recovery of upper-extremity motor function and ADL performance after stroke.

AIM:To explore the survivorship and the mechanism of the intravenous administration of bone marrow stromal stem cells(BMSCs) for treating permanent focal cerebral ischemia in rats.METHODS:After purified,proliferated,and marked with BrdU,the BMSCs were injected intravenously into rats 1 d after focal cerebral ischemia.Modified neurological severity score(mNSS) was evaluated before and following 1,7,14 and 28 d after middle cerebral artery occlusion(MCAO).Rats were executed at 1,7,14 and 28 d after MCAO.Brain sections were stained with hematoxylin and eosin(HE) for determining the infarct volume.Slides were stained by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labeling(TUNEL) and immunostaining for cleaved caspase-3 method for apoptosis detection and mechanism exploration in situ.RESULTS:mNSS in BMSCs-transplanted group at 14th day and 28th day of MCAO was significantly lower than that in control group(P

AIM:To investigate the role of SDF-1? in migrating of bone marrow stromal cells to the injured areas. METHODS:Ischemic brain lesion model was created in rats by permanent middle cerebral artery occlusion (MCAO). 48 SD rats were divided randomly into 2 groups. Group 1:phosphate buffered saline (PBS 1 mL) for control (n=25); Group 2:BMSCs (2?106) were injected intravenously at 24 h after MCAO (n=24). After propagated in BMSCs,Ad5/F35 GFP (green fluorescent protein) was infected to BMSCs. The expression of SDF-1? (stromal cell-derived factor-1?) mRNA in the penrumbral tissue was assayed by real-time quantitative PCR. The expression of CXCR4 on MSCs was detected by flow cytometry. Confocal microscopy was used to detect the GFP-labeled MSCs migration. RESULTS:Ad5/F35 GFP signals was observed in almost infected BMSCs. The expressions of SDF-1? mRNA in the thalamus and hippocampus of the ischemic brains were peaked at 3rd day after stroke,followed by a decrease at 14th day post-ischemia. The expression of SDF-1? mRNA in the cortex of the ischemic brains was peaked at 7th day post-ischemia,still at high level at 14th day post-ischemia. The median percentage of surface CXCR4 expression in BMSCs was 14%. GFP labeled BMSCs were detected in the origination of the middle cerebral artery (olfactory area) at 6 h,after 3 days in the prenumbra tissue such as thalamus,and in the cortex more labeled cells were found after 14 d post-ischemia.CONCLUSION:BMSCs can pass through the blood brain barrier of ischemic rats. Its mechanism might be associated with the expression of SDF-1? in the ischemic brain.

Objective To prove the remarkable inhibitive effect of multiple siRNAs targeting a proliferation-inducing ligand (APRIL) on the human colorectal cancer cell.Methods We constructed a multiple short hairpin RNA(shRNA) expression vector containing four shRNAs (pG4) as well as four single one (pGsh644,pGsh1451,pGsh1938,pGsh2231) against APRIL gene in SW480 cell,and then transfected them into the human colorectal cancer cell line by cationic liposome.Ultimately,SW480 were screened by EGFP to obtain expression cell lines.APRIL expression levels including mRNA and APRIL protein were detected after transfected with all different kinds of vectors.Results A multiple shRNA expression vector containing four shRNAs (pG4) and four single ones were successfully constructed.Four single vectors (pGsh644,pGsh1451,pGsh1938,pGsh2231) and the multiple siRNAs expression vector (pG4) all decreased the APRIL mRNA by 56.2％,49.5％ ;50.9％,49.2％ and 79.3％.And APRIL protein expression was also remarkably reduced,especially by multiple siRNAs expression vector(87.5％).Conclusion Multiple siRNAs expression vector produced a more significant knockdown effect of APRIL than the vectors containing only one APRIL shRNA.What we found suggested us using the vector containing multiple shRNA to silence the expression of APRIL might be exploited as a novel therapeutic strategy for tumors.
