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
ObjectiveTo examine the clinical utility of four methods in diagnosis of tuberculous meningitis.Methods A total of 60 patients with tuberculous meningitis were included as study group and another 70 patients with non-tuberculous intracranial infection as control group. Four methods, including conventional acid fast stain,Myobacterium tuberculous culture in BACTEC MGIT 960, real-time lfuorescent quantitative polymerase chain reaction (FQ-PCR) and modiifed acid fast stain, were used to assay the cerebrospinal lfuid specimens for diagnosis of tuberculous meningitis.ResultsThe positive rate was 11.7% (7/60), 6.7% (4/60), 48.3% (29/60), and 61.7% (37/60), respectively in the study group as tested by the four methods. There was signiifcant difference between the four methods in the positive rate (P< 0.05). Modiifed acid fast stain was more sensitive than the other 3 methods in identifying tuberculous meningitis (P< 0.05). This method also could identify the intracellularM. tuberculosis. All the 8 samples from the 4 patients who were positive for culture ofM. tuberculosis were positive in the modiifed acid fast stain.Conclusions The modiifed acid fast staining method is simple, fast, signiifcantly more senstive in detection of the acid fastM. tuberculosis in CSF, either extracellular or intracellular. It is worthwhile to further investigate its usefulness in early diagnosis of tuberculosis meningitis.

ABSTRACT
Objective To investigate the correlation among mammographic features、pathology and molecu-lar biology markers of breast infitrating ductal carcinoma(IDC) tissues.Methods The mammographic features of 93 cases with IDC confirmed by surgery and histopathology were analyzed retrospectively.The mastectomy specimens of the IDC were stained with immunohistochemistry,and the expression of ER、PR、C-erbB-2 were measured.The rela-tionship between the immunohistochemical pathologic results and mammographic features was analyzed.Results A-mong the 93 cases of IDC,ER positive expression was positively correlated with the spiculate margin of breast cancer (P<0.05);C-erbB-2 positive expression was positively correlated(P<0.05).Moreover,ER and PR positive expres-sion showed a significant inverse correlation with the calcifying of breast cancer(P>0.05);ER and PR positive ex-pression was positively correlated with the transfer of lymph(P<0.05);there existed correlation between the positive expression of C-erbB-2 and lymphatic metastasis and pathohistology grade(P<0.05).Conclusion There was a pos-itive correlation among IDC mammography、pathology and the abnormal value of ER、PR and C-erbB-2.The X-ray mammography could reflect the diagnosis value of ER、PR and C-erbB-2 roughly,and thadpractical value in determi-ning prognoses and endocrinotherapy.
ABSTRACT
Objective To explore the effect of angiotensin-(1-7) [Ang-(1-7)] on proliferation and secretion in cultured rat's glo-merular mesangial cells(GMC) induced by transforming growth factor-β1 (TGF-β1). Methods GMC in logarithmic growth phase were in-cubated, and then were divided into 4 groups: control, Ang-(1-7), TGF-β1,and TGF-β1 + Ang-(1-7) group. Cell numbers of rat's GMC were detected by WST-1. Laminin(LN) and collagenlV (ColⅣ) mRNA expressions in GMC were analyzed by RT-PCR. The secretion of LN and ColⅣ in culture medium of rat's GMC was measured by radioimmunoassay. Results Ang-(1-7) significantly inhibited basal and TGF-β1-induced proliferation of cultured glomerular mesangial cells. Ang-(1-7) significantly down-regulated LN and Col Ⅳ mRNA expressions in glomerular mesangial cells and also inhibited the secretion of LN and ColⅣ induced by TGF-β1(P <0. 05). Conclusions Ang-(1-7) can inhibit basal and TGF-β1-induced proliferation, and inhibit ECM secretion of cultured rats glomerular mesangial cells.
