Objective To study the clinicopathological characteristics and prognosis of asymptomatie IgA nephropathy (IgAN) children with pmteinuria and/or microscope haematuria .Methods Clinical and pathological characteristics of 54 children with IgA nephropathy confirmed by renal biopsy were analyzed . These children with IgAN were divided into two groups according to their clinical characteristics at the first onset: asymptomatic IgAN group (AsIgAN) and symptomatic IgAN group (SIgAN) . Histologic changes were classified by Lee SM and Katafuchi semiquantitative scoring system . Results Eighteen children were in AslgAN group and 36 children were in SIgAN group . The degree of proteinuria in SIgAN group [(2 .3±2 .2) g/d] was higher than that in AslgAN group [(0 .4±0 .3) g/d] at the time of biopsy (P＜0 .05) . Although asymptomatic IgAN children were mainly of Lee's type Ⅰ ～Ⅱ, 2 children (11%) were of Lee's type Ⅳ～Ⅴ and 5 cases (27%) presented interstitial injury . Symptomatic IgAN children were mainly of Lee's type Ⅱ ～Ⅲ, there was no significant difference between two groups (P＞0 .05) . Urine micrealbumin was increased in 87% children presented with microscope haematuria . After an average of (26 .9±8 .8)months follow-up, only one case of Lee's Ⅴ progressed into renal failure and the others maintained normal renal function . Conclusions Although children with asymptomatic IgAN have minor clinical symptoms, severe renal pathological lesion and poor prognosis also occur . Urine screening helps to detect renal diseases and renal biopsy should be performed in the patients with increased urine microalbumin .

Objective To analyze of the relationship between level of anxiety and depression before surgery and anus exhausting time for patients after gynecological abdominal surgery.Methods A descriptive study was conducted with a survey of 100 cases of patients with gynecological abdominal surgery where the level of anxiety and depression before surgery and post-anus exhausting time were analyzed to explore the correlation between them.Results In the 88 valid questionnaires,the incidences of stress and anxiety before surgery were respectively 38.64％(34/84) and 19.32％(17/88) and the average anus exhausting time after surgery was (44.55 ± 13.90) hours;the anus exhausting time of anxious patients was significantly longer than that of non-anxious patients [(48.35±12.84) hours vs.(42.50±14.13) hours,t=-2.12,P＜0.05] and bivariate Logistic regression analysis suggested that preoperative level of anxiety had a significant effect on anus exhausting time after surgery.Conclusions Stress,anxiety and other negative emotions can affect anus exhausting time after surgery and level of anxiety could be used as one predictor of the delay of anus exhausting time after surgery.

Objective To analyze the changes and characteristics of cancer incidence and mortality among Jiaxing residents in the past 6 years,and to provide evidence for the prevention and control of cancer incidence and mortality.Methods Registered malignant tumor data from the Zhejiang Chronic Disease Information Monitoring and Management System were collected and analyzed based on the International Statistical Classification of Diseases (ICD-10).The statistical indexes used for analyses included crude incidence,standardized incidence,crude ortality,standardized mortality,potential years of life lost (PYLL),average years of life lost (AYLL),rate of potential years of life (PYLL‰) and so on.Results From 2010 to 2015,the crude incidence,the standardized incidence,the crude mortality,and the standardized mortality were 342.52/105,240.89/105,194.71/105 and 126.27/105,respectively.The crude incidence and mortality for males were both higher than those for females(378.44/105 vs.307.49/105,x2=763.06,P＜0.01;255.31/105vs.135.62/105,x2-3 814.11,P＜0.01).The PYLL,AYLL and PYLL‰ of residents in Jiaxing were 248,307 years,6.16 years and 12.00‰,respectively.The PYLL‰for males was significantly higher than that for females(x2=37073.85,P＜0.01).The AYLL for females was 6.50 years,higher than that for males(5.98 years)(t =125.15,P＜0.01).The incidence of malignant tumors increased with age,especially in the older than 40 age group,with the older than 80 age group showing the highest rate at 1 779.01/105 (x2 =38 840 907,P ＜ 0.01).Rates for Lung cancer (70.59/105),colorectal cancer (39.86/105),liver cancer (29.14/105),breast cancer(26.73/105) and stomach cancer (26.00/105) were the most common malignant tumors in Jiaxing.Conclusions The morbidity and mortality of malignant tumors are showing signs of rising and the incidences of lung cancer and gastrointestinal cancer are particularly pronounced in Jiaxing.In consequence,measures for the prevention and control of malignant tumors should be developed with clearly defined objectives and research on the pathogenesis of malignant tumors should be stepped upto reduce the incidence and mortality of malignant tumors.

Objective To detect the serum prohibitin protein(PHB)level in children with renal interstitial damage and analyze the correlation between PHB and renal interstitial fibrosis(RIF). Methods Serum PHB protein levels were determined by Western blot analysis in 36 children with kidney diseases,and 30 healthy children were studied as control. Levels of BUN,Scr,and urinary microprotein series(including ALBU/Cr,NAGU/Cr,IgG U/Cr,α1-MU/Cr)were studied by automatic biochemical analyzer. Renal interstitial damage was semiquantitatively graded according to Katafuchi's method. The correlation between serum levels of serum PHB protein and those of BUN,Scr as well as urine microprotein were analyzed. Results Serum PHB protein was positive in children with diverse kidney diseases however it was negative in the normal controls(P ＜ 0.05). Serum PHB levels were significantly higher in children with proliferative glomerulonephritis than those with non-proliferative glomerulonephritis(P ＜ 0.05). Statistical analysis indicated that serum PHB levels positively correlated with the degree of tubulointerstitial lesions(r ＝ 0.868,P ＜ 0.001)as well as the glomerular injuries(r ＝ 0.753,P ＜ 0.001). And,serum PHB levels were also positively correlated with urinary microprotein including NAG(r ＝ 0.586,P ＜ 0.001)and IgG(r ＝ 0.341,P ＜ 0.001). Conclusions Serum PHB levels were significantly increased in children with kidney diseases and were positively correlated with the degrees of renal interstitial damage,suggesting that PHB might be a potential clinical marker for detecting tubulointerstitial lesions.

Objective To examine the expression of response gene to complement 32 (RGC-32) in renal tissue of children with IgA nephropathy (IgAN), and to explore its significance. Methods The subjects were 45 children diagnosed as IgAN by renal biopsy. The expression of RGC-32, α-smooth muscle actin (α-SMA) and transforming growth factor β1 (TGF-β1) was examined by immunohistochemistry staining. The correlation of RGC-32 expression with α-SMA,TGF-β1, degree of renal pathological lesions and clinical index in IgAN was assessed by Spearman correlation analysis. Results RGC-32 protein located in renal tubular epithelial cells in normal and IgAN renal tissues. The positive expression index of RGC-32 in nomal group, IgAN mild group, moderate group and severe group was (18.29±6.22)%, (23.90±9.65)%, (31.23±9.86)%,and (34.52±10.63)% respectively. With more severity of renal pathological lesions, the expression of RGC-32 in IgAN was enhanced. The RGC-32 expression was positively correlated with the score of glomerulus and renal interstitium in children with IgAN (r=0.385, 0.347, P＜0.05), as well as α-SMA, TGF-β1 (r=0.594, 0.521, P＜0.01), but was not correlated with Scr, urinary NAG/Cr,Alb/Cr, IgG/Cr, and α1-M/Cr (r =0.117, -0.115, -0.138, -0.176, -0.028, all P ＞0.05).Conclusions RGC-32 protein locates in renal tubular epithelial cells in normal and IgAN renal tissues. RGC-32 may participate in the course of renal tubulointerstitial lesions in children with IgAN, especially in the course of epithelial-mesenchymal transition (EMT) induced by TGF-β1.
