Objective To investigate the cause and related factors of hospitalization in patients with diabetic nephropathy with maintenance hemodialysis.Methods Fifty-six patients of diabetic nephropathy were enrolled in current study who hospitalized in Beijing Tongren Hospital affiliated to Capital Medical University from March 2009 to February 2012.All subjects were divided into hospitalized group (n =29) and non hospitalized group (n =27).The information including age,dialysis age,blood pressure,hemoglobin,blood glucose,serum creatinine,serum potassium,plasma albumin,serum calcium,serum phosphorus,albumin,intact parathyroid hormone (iPTH) and hemodialysis sufficienc (KT/V) were collected.Stepwise multiple regression analysis was applied to explore the main causes and related risk factor.Results Twenty-nine out of 56 patients were hospitalized and they had 56 hospitalization records during 24 months of observed period.Average hospitalization was 1.0 times per patient and hospitalized days were (29.62 ± 14.30) days per hospitalized patients.The main causes of hospitalization were cardiac vascular diseases (35.7％),vascular access stenosis (30.4％),and pulmonary infection (17.8％).Compare with non-hospitalization group,age of patient hospitalization group was older((66.97 ± 9.94) vs.(57.42 ± 11.77),t =2.917,P =0.02) and the level of albumin and Kt/V were lower(albumin:(34.02 ± 4.76) vs.(38.93 ± 3.82),t =-4.573,P =0.000 ; Kt/V:(1.16 ± 0.09) vs.(1.39 ± 0.18),t =6.503,P =0.000).Stepwise multivariate regression analysis showed plasma albumin and KT/V were risk factors to influence the hospitalization in diabetic patients undergoing maintenance hemodialysis (β =-1.724,-0.040 respectively,P =0.00,0.02 respectively) Conclusion Cardiovascular disease,vascular access stenosis and pulmonary infection were the important factors for hospitalization in hemodialysis patients with diabetic mellitus.Cardiovascular disease was the top reason of hospitalization in diabetic patients with maintenance hemodialysis.Hypoalbuminia and inadequacy dialysis were risk factors to influence the hospitalization in diabetic patients undergoing maintenance hemodialysis.

Objective To clarify the MUM1/IRF4 expression in follicular lymphoma (FL) and its clinical and pathological significance. Methods Ninety-six cases FL were immunostained with MUM1,CD10,bcl-2,bcl-6 and Ki-67 antibodies. The results were compared with their clinical and pathological features. Results The overall MUM1 expression rate in FL was 59.2 % (58/96),including 36.2 % (19/51) grade 1 or 2 and 86.4 %(39/45) grade 3 cases (x2 =24.406,P <0.001). 68.9 % cases with diffuse area were MUM1 positive (x2 =8.161,P =0.004). MUM 1 and CD10 expression had inverse correlation,83.3 % CD10 negative cases were MUM1 positive (x2= 12.649,P<0.001). The mitosis rate and Ki-67 label index were statistically higher in MUM1 positive cases than in negative cases (t = -3.852 & -4.610,respectively,P <0.001). Conclusion MUM1 can be used as a biomarker to divide FL into different malignancies. The MUM1 positive FL may be the feature of high grade non germinal center B cell malignant lymphoma.

Objective:To investigate the therapeutic mechanism of high-frequency repetitive transcranial magnetic stimulation (rTMS) in treating mild amnestic cognitive impairment (aMCI).Methods:Twenty-five patients with aMCI were randomly divided into an observation group of 13 and a control group of 12. The observation group was given 10-Hz rTMS over the left dorsolateral prefrontal cortex at 80% of the motor threshold-400 pulses a day, 5 times a week for 4 consecutive weeks. The control group received sham stimulation on the same schedule. Before and after the experiment, both groups were evaluated using the Montreal cognitive assessment (MoCA) and received fMRI scans.Results:After the intervention, the average MoCA score of the observation group had improved significantly more compared with that of the control group and compared with before the intervention. According to the fMRI results, regional homogeneity in the right middle frontal gyrus of the observation group had increased significantly, while that of the control group both there and in the left precuneus had decreased significantly.Conclusions:High-frequency rTMS can effectively improve the cognitive function of patients with aMCI and synchronize neuron activity in cognition-related brain regions.

Objective To investigate the application value of Multi-Latex polygranular technique joint detection of kidney injury-related urinary microproteins in noninvasive diagnosis after renal transplantation. Methods Clinical data of 72 recipients undergoing renal transplantation were retrospectively analyzed. According to the level of serum creatinine (Scr), the recipients were divided into normal renal function group (group A, n=14), mild kidney injury (group B, n=37), and severe kidney injury group (group C, n=21). 20 healthy volunteers were selected as the healthy control group (HC group). The contents of urinary retinol binding protein (RBP), microalbumin (mAlb), IgG, transferrin (TRF), α₁-microglobulin (MG), and β₂-MG of subjects in each group were detected using the Multi-Latex polygranular technique. The correlation between urinary microproteins and Scr, blood urea nitrogen (BUN) was analyzed. The differences of urinary microproteins in each group were compared. And the diagnostic value of single and joint detection of urinary microproteins was evaluated. Results Six kinds of urinary microproteins in HC group and group A were significantly lower than those in group B and group C, and six kinds of urinary microproteins in group B were significantly lower than those in group C (all P < 0.01). Six kinds of urinary microproteins in renal transplant recipients were positively correlated with BUN. RBP, mAlb, α₁-MG, and β₂-MG were positively correlated with Scr. The correlations were statistically significant (P < 0.001-0.05). The diagnostic value of joint detection of urinary microproteins is better than the detection of single index, among which TRF+mAlb+RBP+α₁-MG quadruple detection had the highest diagnostic value. Conclusions Six kinds of urinary microproteins can be used as specific indicators to reflect graft renal function. The polygranular technique can simultaneously detect its contents and achieve noninvasive diagnosis. The diagnosis based on TRF+mAlb+RBP+α₁-MG quadruple detection is expected to further improve the noninvasive diagnosis system after renal transplantation.
