ABSTRACT
BACKGROUND:A previous study by our group found that protein phosphatase 2Cm(PP2Cm)null mice developed significantly fewer symptoms of renal failure relative to wild-type mice,and thus it was speculated that PP2Cm may play an important protective role in the development of renal fibrosis,however,the molecular mechanisms remain undefined. OBJECTIVE:To investigate the effect of the PP2Cm gene on the transcriptome of human renal tubular epithelial cells. METHODS:Cultured human renal tubular epithelial cells were transfected with the PP2Cm gene into human renal tubular epithelial cells using plasmids.The expression of PP2Cm in the cells was detected by fluorescence quantitative PCR assay and western blot assay,and subsequently,cell RNA was separately extracted for transcriptome sequencing to look for differentially expressed genes between transfected and control groups.The resulting differential genes were further subjected to GO analysis and KEGG analysis using bioinformatics methods. RESULTS AND CONCLUSION:There were 796 differentially expressed genes,553 of which were downregulated genes and 243 upregulated genes,in human renal tubular epithelial cells transfected with the PP2Cm gene compared with untransfected blank cells by sequencing analysis.GO analysis results showed that the upregulated genes were significantly enriched in cellular biosynthetic processes,protein translation,intrinsic apoptotic signaling pathways,and so on.The downregulated expressed genes were significantly enriched in endothelial cell proliferation,cell adhesion and other signaling pathways.KEGG analysis results showed that the significantly up-regulated genes were enriched in metabolism-related signaling pathways such as amino acid metabolism and biosynthesis.The downregulated expressed genes were significantly enriched in signaling pathways such as pantothenate and coenzyme A biosynthesis.Our results show that PP2Cm overexpression can affect a number of signaling pathways related to a range of biological processes in renal tubular epithelial cells,which may be important in metabolism-related signaling pathways such as amino acid metabolism and biosynthesis.

ABSTRACT
Objective To investigate the incidence of fatigue in maintenance hemodialysis(MHD)patients and its related factors.Methods A total of 289 patients on MHD between January 2016 and March 2017 in hemodialysis centers of the First Affiliated Hospital of Xinjiang Medical University,Xinjiang Yili Kazak Autonomous Prefecture Friendship Hospital,and Yili Prefecture Hospital were enrolled.Internationally standard fatigue rating scale(FAI)was applied to assess the incidence of fatigue in MHD patients,and subjective comprehensive nutrition assessment(SGA)protein energy wasting rating scale was used to assess protein energy wasting(PEW)conditions.All patients were divided into the fatigue group and the non-fatigue group according to the FAI score.The clinical data and the blood biochemical indicators in two groups were compared.The risk factors of fatigue in MHD patients were analyzed by logistic regression method.Results The incidence of fatigue was 83.0%in MHD patients,and the rate of PEW was 62.6%.Blood total cholesterol in the fatigue group was lower than that of the non-fatigue group(P < 0.05).The difference between SGA scores of two groups had statistical significance(P < 0.001).Single factor logistic regression analysis results showed that higher SGA score(OR=1.312,95%CI:1.163-1.481,P < 0.001),lower blood total cholesterol(OR=0.661,95%CI:0.496-0.880,P=0.005)were risk factors of fatigue in MHD patients.Multivariable logistic regression analysis results showed that higher SGA score(OR=5.286,95%CI:2.078-13.442,P < 0.001)was an independent risk factor of fatigue in MHD patients.Conclusions The incidence of fatigue and PEW are high in MHD patients.PEW is an independent risk factor of fatigue in MHD patients.
ABSTRACT
OBJECTIVE To investigate the effect of Turkish galls extract (TGE) on the expression of IgA in serum,urine and renal tissue of IgA nephropathy (IgAN) model rats.METHODS Fifty healthy male Sprague Dawley rats were randomly divided into normal control group,IgAN model group,and TGE 75,150 and 300 mg· kg-1 groups,10 rats per group.The model of IgAN rats was established with bovine serum albumin (BSA)+lipopolysaccharide (LPS)+carbon tetrachlorid (CCl4)for 12 weeks.From the 13th week,TGE was ig administrated once a day for 4 weeks.At the end of the 12th and 16th weeks,24 h urine protein was measured by BCA method.At the end of the 16th week,serum and urinary IgA levels were measured by enzyme linked immunosorbent assay(ELISA),serum creatinine(SCR) and blood urea nitrogen (BUN) were detected by an automatic biochemical analyzer,and the renal pathological changes were evaluated with an Oxford classification scoring system.The deposition of IgA immune complex in the kidney was observed by immunofluorescence assay.RESULTS At the end of 12th week,24 h urine protein increased in all IgAN groups (P<0.05),compared with normal control group.At the end of 16th week,24 h urine protein,IgA content in serum and urine,SCr and BUN content in serum,score in Oxford classification of renal tissue and deposition of IgA immune complex in the kidney in IgAN model group were all higher than in normal control group (P<0.05).Compared with IgAN model group,24 h urine protein,IgA content in serum and urine and SCr content in serum were decreased in all TGE groups (P<0.05),and BUN content in serum and deposition of IgA immune complex in the kidney decreased in TGE 150 and 300 mg·kg-1 groups (P<0.05).The score in Oxford classification of renal tissue was decreased in TGE 300 mg· kg-1 group only.CONCLUSION TGE has curative effect on IgAN model rats by reducing serum and urinary IgA and decreasing IgA immune complex deposition.
ABSTRACT
Objective To investigate the incidence and risk factors of acute kidney injury (AKI) in patients with multiple soft tissue contusion.Methods A total of 513 patients diagnosed as multiple soft tissue contusion in the First Affiliated Hospital of Xinjiang Medical University from January 1,2008 to January 1,2013 were retrospectively analyzed.Demographics,clinical data and laboratory examinations before and after AKI were collected and analyzed.Results The age of all subjects was 31.30 (12-78) years old with the male to female ratio of 2.1∶ 1.AKI occurred in 74 cases with an incidence rate of 14.4%.No AKI was observed in patients with assault injuries,while AKI was found in 27 cases (36.5%) with car accident injuries and 4 cases (5.4%) with other injuries.AKI showed in 1 case(1.4%) with damaged area under 1%,in 4 cases(5.4%) with damaged area ranged from 1% to < 3%,10 cases (13.5%) with damaged area ranged from 3% to 5% and 19 cases (25.7%) with damaged area over 5% with significant difference among the groups (P < 0.01).Incidence rate of AKI was significantly higher in patients with chronic kidney disease (CKD) than those without CKD (54.5% vs 20.3%,P < 0.01).Two of the AKI cases died,with a mortality rate of 2.7%.Multivariate logistic regression analysis showed that the followings were the independent risk factors for the occurrence of AKI in patients with multiple soft tissue injuries:age (OR =1.996),basic serum creatinine (OR =0.976),basic evaluated GFR (eGFR) (OR =0.964),serum potassium (OR =2.117),myoglobin (OR =0.950) and damaged area (OR =1.811).Conclusions Incidence rate of AKI is quite high in multiple soft tissue contusion.Age,basic serum creatinine,basic eGFR,serum potassium,myoglobin and damaged area are the independent risk factors for the occurrence of AKI in patients with multiple soft tissue injury.
ABSTRACT
Objective To explore the influence of living donor renal transplantation on the safety of donors.Methods Sixty-two donors who underwent living donor renal transplantation in the First Affiliated Hospital of Xinjiang Medical University from April 2003 to April 2007 were selected as research objects.The operation time and length of stay of donors were recorded.The occurrence of postoperative complication and prognosis were observed.Postoperative follow up included serum creatinine (Scr),blood urea nitrogen (BUN),glomerular filtration rate (GFR),plasma albumin,hemoglobin,blood pressure and the influence of kidney donation on life and work.Results The operations of 62 donors were successful.One case developed pneumothorax during open nephrectomy and another case developed fat liquefaction and necrosis of incision.Both of them were cured after symptomatic treatment.Two cases developed pulmonary infection postoperation and were cured after the treatment of sensitive antibiotics and aerosol inhalation.The other cases recovered smoothly after operation.In 62 donors,the average postoperative length of stay was (8.2 ±2.6)d,and the follow-up time was (3.2 ±1 .1 )years.All of the donors survived without influence on life and work.No significant difference was observed in the changes of Scr,BUN,GFR,plasma albumin,hemoglobin,blood pressure of the donors before operation and 7 d,3 months,1 year,3 years,5 years after operation (all in P >0.05).Conclusions The living donor nephrectomy is safe and feasible.It is very important for assuring the safety of donors to examine living donor perfectly before operation,be careful during operation,and closely follow up after operation.
ABSTRACT
Objective To analyse the relationship and mechanism between chronic periodontitis (CP) and IgA nephropathy (IgAN) by establishing animal model of chronic periodontitis and IgA nephropathy in SD rats.Methods Eighty health male SD rats were divided into four groups,control group (A,n=20),IgAN group (B,n=20),CP group (C,n=20),CP accompanied with IgAN group (D,n=20).CP model was established by ligating silk suture and besmeared pathogenic bacterium in rats dental cervix.Experimental IgAN model was established by lavage of bovine serum albumin (BSA) and injection of lipopolysaccharide (LPS) and carbon tetrachloride (CCl4).Ten rats were sacrificed in every group at the end of week 8 and 12.The blood,urine,kidney tissue samples were examined.The observation index included proteinuria,kidney and liver function,renal tissue pathology and periodontal tissue pathology.The data were statistically analysed.Results Animal models were established successfully.The levels of Scr and BUN in group A,B,C were not obvious difference,but that in group D was higher than the other third groups at 8 weeks (P < 0.05).The levels of Scr and BUN in group D and group B were significantly higher than that in group A,meanwhile that in group D was significantly higher than that in group B at 12 weeks(P < 0.05).The levels of 24 h urine protein in B,C,D groups were higher than that in group A at 8 weeks(P < 0.05),but at 12 week,that in group D was higher than that in group B and C (P < 0.05).At 8 weeks,glomeruli had little mesangial broadening and renal interstitium had mild hyperplasia of fibrous tissue in group B and D,and that in the group D significantly was heavier than that in group B.The focal varying degrees were glomerular mesangial proliferation hardening,glomerular mesangial broadening,focal segmental sclerosis,and diffuse or focal inflammatory cell infiltration in D group at the end of week 12.The score of PAS between group A and group C had no statistical significance.The scores of PAS in group B and D were higher than that in group A (P < 0.01),and that in group D was higher than that in group B (P < 0.01).Obvious inflammation of periodontal tissue was observed in group C and D,and modified sulcus bleeding index (MBI) were higher than that in group A and B,and MBI in group D was significantly higher than that in group C (P < 0.01).Conclusions The model can be used to research the change of biochemistry and pathology and observe the relationship between chronic periodontitis and IgAN.This study shows that there is relationship between chronic periodontitis and IgAN.Chronic periodontitis maybe make more serious pathology damage in kidney by inflammation mechanism.
ABSTRACT
Objective To investigate the factors implicated in the outcomes of patients with invasive pulmonary aspergillosis (IPA).Methods During a 5-year period,65 patients with IPA met the criteria set by the European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG)in 2008 were retrospectively evaluated. The initial CT findings of eligible patients were reviewed by two senior radiologists who specialized in chest radiology.Patients were divided into the survivor (n =43 ) and non-survivor (n =22) groups according to their survival as long as 3 months after the diagnosis of IPA was made.An initial univariate analysis was used to screen variables that were related to prognosis,followed by a multivariate logistic regression analysis to examine these variables. Results Of the 65 IPA patients analyzed,23 (35%) had a proven diagnosis and 42 (65%) were probable ones.The univariate analysis showed that the rates of extra-pulmonary infection,uncontrolled underlying diseases and invasive mechanical ventilation were significantly different between the 3-month survival group and the non-survival group ( P <0.05,respectively),whereas chest CT findings,including air-space consolidation/massive consolidation,macronodules,infarct-like macronodules,halo signs, ground-glass opacities,small nodules,hypodense signs,cavities,crescent signs,small-airway findings,bronchial wall thickening/bronchiectasis,pleural effusion and hydro-pericardium, were not significantly different between the two groups (P > O.05,respectively).Logistic regression analysis revealed that an uncontrolled underlying disease was the only independent predictor of 3-month mortality in patients with IPA (P =0.001,OR:O.024,95 % CI:O.003 ~0.223,B =- 3.714,SE =1.129,Wald =10.821 ). Conclusions An uncontrolled co-morbidity was the only independent predictor of mortality within 3 months in patients with IPA.The initial CT findings did not confer any informatioin of implication in predicting the outcomes of IPA patients.
ABSTRACT
ObjectiveTo investigate the prevalence rate and risk factors of inpatients with coronary atherosclerotic heart disease (CHD) combined chronic kidney disease (CKD).MethodsAll people who underwent CHD combined CKD in CHD department of the First Affiliated Hospital of Xinjiang Medical University during January to December 2009 were enrolled in the retrospective study.Results A total of 960 hospitalized patients with CHD were enrolled during the observation period. The prevalence of proteinuria and reduced eGFR were 11.04% and 10.52%,respectively.The total CKD prevalence rate was 16.77%,with male of 16.67% and female of 17.11%.There was no significant difference in prevalence rate between male and female( P > 0.05 ).The multi-factors logistic regression analysis showed that diabetes mellitus(OR 2.60,95%CI 1.17-3.29) was risk factor for CHD combined proteinuria.Ten-years older in age( OR1.55, 95%CI1.31-1.83 ), diabetesmellitus ( OR1.69, 95%CI1.15-2.47 ),hypercholesterolemia ( OR 2.89,95% CI 1.49-5.61 ),and hyperuricemia( OR 1.49,95% CI 0.96-2.33 )were risk factors for CHD combined CKD.

ABSTRACT
Objective To investigate the correlation between the changes of left ventricle and age,duration,blood-pressure,hemoglobin,serum creatinine level and glomerular filtration rate (GFR) in lupus nephritis (LN) patients.Methods One hundred and thirty-two patients with systemic lupus erythematosus (SLE) were divided into LN group and non-LN group,the clinical data were analyzed with t test,x2 test,Pearson correlation analysis and multiple regression analysis.Results Compared with non-LN patients (4/67,6% ),the incidence of concentric hypertrophy was significantly increased in LN patients ( 14/65,22% ) (x2=6.790,P<0.05 ).Left ventricular end systolic internal dimension (LVESd) was correlated positively with blood uric acid (BUA) level (B=0.014,P<0.01 ).Left ventricular mass index (LVMI) was correlated positively with blood urea nitrogen (BUN) level (B=2.977,P<0.01 ).lnter-ventricular septal thickness (IVST) was correlated positively with systolic blood pressure (B=0.022,P<0.01 ).Conclusion Compared with non-LN patients,the incidence of concentric hypertrophy is significantly increased in LN patients.It may be one of the mechanisms that SLE could involve kidney,which consequently lead to hypertension,higher BUN and BUA level,which may further aggravate heart damage in turn.
ABSTRACT
Objective To investigate the prevalence and risk factors of chronic kidney disease(CKD)in the adult population receiving healthy examination from Xinjiang. Methods A total of 10 025 subjects who were older than 20 years and received healthy examination in Health Center of the First Affiliated Hospital,Xinjiang Medical University,from January 2009 to April 2010 were enrolled. Results The prevalence of proteinuria was 4.86%(95%CI:4.44%-5.28%),hematuria 3.13%(95%CI:2.79%-3.47%),and reduced eGFR 2.66%(95%CI:2.34%-2.98%).Approximately 9.60%(95%CI:9.02%-10.18%)of these subjects had at least one indicator of kidney damage.Albuminuria was independently associated with male,systolic blood pressure,BMI,glycometabolism abnormity, hypertriglyceridemia.Hematuria was independently associated with female,minority,aystolic blood pressure.Reduced eGFR was independently associated with female,age,obesity,hyperlipidemia,hyperuricemia.Age,gender,glycometabolism abnormity,systolic blood pressure,hyperuricemia and hyperlipidemia were independently correlated with CKD. Conclusions The prevalence of chronic kidney disease is 9.60%in the adult population receiving healthy examination,which is quite high and should be considered.The spectrum and correlated factors of CKD in this population are similar to studies reported.
ABSTRACT
Objective To study the relationship between periodontitis and chronic kidney disease (CKD) among Uygur adults of Xinjiang. Methods Data of 1650 Uygur adult residents (age>18 years) in the Moyu county, Xinjiang were analyzed. The subjects were sampled randomly with stratify capacity from 15 villages among 364 villages. All the subjects received the questionnaire and the oral examination. The markers and risk factors of chronic renal injury were inspected. The subjects were categorized as periodontitis group and non-periodontitis group according to chronic periodontitis diagnostic criteria. The periodontitis group was further divided into mild, moderate and severe periodontitis. Results The data of 1415 subjects were completed. The prevalence of chronic periodontitis was 65.2% (95%CI:65.0-65.4). The prevalence of CKD was 5.2% (95%CI:5.1-5.3). Albuminuria was found in 4.2% (95%CI:4.1-4.3) of subjects. 1.3%(95%CI:1.3-1.4) of individuals had renal insufficiency. In periodontitis group, the prevalence of CKD was 6.4%, which was higher than that in non-periodontitis group 2.9% (χ2=7.841 ,P=0.005).Univariate regression analysis showed that severe periodontitis was risk factor of CKD (OR =3.2,95% CI:2.0-5.2). Multivariate logistic regression analysis showed that severe periodontitis was independently associated with CKD (OR = 1.9, 95%CI: 1.1-3.3). Conclusions In Uygur adults of rural area of Xinjiang, the prevalence of CKD is higher in periodontitis group as compared to non-periodontitis group. Severe periodontitis is an independent risk factor of CKD.
ABSTRACT
Objective To investigate the possible correlation between chronic periodontitis(CP)and chronic renal failure(CRF)by establishing chronic periodontitis and chronic renal failure model in SD rats. Methods Forty health male SD rats were divided into four groups: control group(A), CP group(B), CRF group(C), CP accompany with CRF group(D). Ten rats were sacrificed in every group at the end of week 8. The periodontal index, levels of serum Scr and BUN, the concentration of IL-1β and TNF-α were examined. The severity CP and CRF was quantified by histopathology. The date was statistically analyzed. Results Animal models were established successfully.

The kidney change of inflammation was observed in group B, the grade of PAS and Masson in group C and D were higher than that in group A(P<0.01), and that in group D was higher than group C(P<0.05). Obvious inflammation of periodontal tissue was observed in group B and D. Attachment loss level(AL)in group D was higher than that in group B[(173.60± 16.75)μm vs(124.00±23.87)μm, P<0.05]. The level of IL-lβ and TNF-α in group B and C and D were higher than that in group A(P<0.05), and IL-lβ in group D was higher than that in group B and C(P<0.05), TNF-a in group D was higher than that in group B(P<0.05). 2×2 factorial design revealed that there were interactions between CP and CRF on the numerus of Scr and BUN and AL P<0.05), and the influence of each factor on that was significant(P<0.05), no interactions were noted between CP and CRF on IL-1β and TNF-α(P>0.05), but the influence of each factor on that was significant(P<0.05). Conclusions The SD rat models can appear chronic periodontitis and chronic renal failure at the same time. There is correlation between chronic periodontitis and chronic renal failure. Chronic periodontitis can aggravate chronic renal failure throngh the role of inflammation.
ABSTRACT
Objective To investigate the association of prevalence of periodontitis with metabolic syndrome (MS). Methods Data were analyzed from 1 650 Uygur rural residents in Moyu County. The subjects, aged over 18 years, were sampled randomly from 15 villages out of total 364 villages. Questionnaire, oral examination, and blood biochemical indicators were collected. The subjects were divided into groups with and without periodontitis based on chronic periodontitis diagnostic criteria, and the group with periodontitis was further divided into subgroups, each with mild, moderate, and severe periodontitis respectively. The diagnosis of MS was madeaccording to the definition of the International Diabetes Federation in 2005. Results Among 1 415 subjects whosedata were complete, there were 275 ( 19.4% ) subjects with MS and 934 (66.0%) subjects with periodontitis. The prevalence of MS was higher in the group with periodontitis than that without perionontitis (23.1% vs 12.3%, x2=23.9, P<0. 001 ). The prevalence of MS was increased with the grade of periodontitis, being 19.8%, 20.8%,27.6% in the mild, moderate, and severe periodontitis groups, respectively(x2= 31.9, P<0. 001 ). Multiple logistic regression analysis showed that the risk of MS increased with the grade of periodontitis, with OR 1. 6, 1.7,1.9, respectively, in the groups with mild, moderate, and severe periodontitis compared with that without perionontitis ( P<0.05 or P<0.01 ). Conclusions The prevalence of MS was related to periodontitis in the Uygur nationality and increased with the grade of periodontitis.
ABSTRACT
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 (0<r<1, P <0.01), for those patients with LN type Ⅴ, their score BILAG2004 and kidney biopsy AI was positively correlated (0<r<1, P<0.05).③BILAG2004 score had stronger correlation with AI than SLEDAI2000. ④SLEDAI2000 score with AI in patients with type Ⅲ LN had the strongest association, followed by type Ⅱ. BILAG2004 score with AI in patients with type Ⅲ LN had the closet association, followed by type Ⅳ. ⑤ BII,AG2004 score, SLEDAI2000 score and CI, TIL had no significant association in all patients groups (P>0.05). 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.
