Objective To investigate the clinical characteristics of radiographic contrast-induced nephropathy(RCIN) in children for improving the knowledge of this disease.Method The clinical data of 6 hospitalized children with RCIN collected from Oct.1998 to Dec.2007 were evaluated retrospectively.Results Of 92 patients who had cardio-angiography,intravenous pyelography,renal arteriography,cerebral angiography,and CT with contrast medium,6 cases(2 girls and 4 boys,aged 2-17 years old) had RCIN.Among the 6 children,5 cases [serum creatinine(Scr) was from 168.3 to 249.7 ?mol/L] showed non-oliguria-type acute renal failure;1 case(Scr was 583.1 ?mol/L) showed oliguria-type acute renal failure,and renal biopsy pathology findings showed that renal tubular epithelial cells were vacuolar degene-ration,striated border fell off,renal tubular epithelial cells were necrotic mulifocally,while the glomeruli were normal.Hematuria in 2 cases with primary disease aggravated;2 cases showed microscopic hematuria;1 case had proteinuria(+),1 case appeared microscopic hematuria and proteinuria(+).Five patients with non-oliguria-type acute renal failure were cured successfully after the medication of 10-21 days.Another case with oliguria-type acute renal failure was well after interrupted hematodialysis for 13 days and medication.Conclusion Children suffering RCIN usually manifest non-oliguria-type acute renal failure,and most of them can be cured by hematodialysis and medication mostly.

A clinical laboratory information system consists of two parts--the information system and the management system. Its development is based on scientific and rational lab-workflow, consulting the international standard HL7 Protocol, and combined with barcode technique and instrument communication. The information system mainly manages the data which come from the whole lab testing process while the management system is dominating the lab office work and management decisions.

Objective To explore the effect of Bailing capsule on epithelial-mesenchymal transition( EMT) in rats with adenine-in-duced tubulointerstitial fibrosis. Methods Tubulointerstitial fibrosis animal models were established and SD rats were divided into mo-del group ( n = 30), treatment group ( n = 30) and control group( n = 30), randomly. Experimental rats were harvested at 7 w, 12 w,17 w after onset of experiment and functional evaluations were performed. Histology, immunohistology were examined to investigateboth histolopathology changes and the expression of bone morphogenic protein-7 (BMP-7), transforming growth factor-β1 (TGF-β1 )and a-smooth muscle actin (α-SMA) in kidneys at three time points mentioned above, respectively. Results Compared with controlgroup, 24 h urinary protein in model group lost increasingly and significantly difference appeared at three time points relative to controlgroup ( P ＜ 0.01 ). Urinary NAG in model group was markedly higher than that in control group from 7 w after onset (P ＜ 0.01 ) andwas increasingly raised at 12 w and 17 w (P＜0.01). The value of blood BUN and Cr in model group increased at 7 w (P＞0.05) rel-ative to control group. There was significant difference at 12 w and 17.w (P ＜ 0.01 ). Histologically, kidneys in model group, at 7 w,exhibited tubular casts and gently tubular dilation, granuloma in cortex, mononuclear cells infiltration in tubulointerstitial areas, andmild interstitial fibrosis. At 12 w, the degree of tubular injury and tubulointerstitial fibrosis gradually aggravated. Up to 17 w, diffusetubular dilation or atrophy was observed and focal tubules disappear. Diffuse interstitial fibrosis was exhibited. In normal kidneys, im-munohistochemistry suggested that the light expression of BMP-7 was detected in proximal renal tubular epithelial cells and marked ex-pression was identified in distal tubule, collecting duct, and renal tubular epithelial in junction area between cortex and medulla. How-ever, the expression of BMP-7 in kidneys of model group significantly decreased with increasing tubulointerstitial fibrosis and was nega-tive correlation with the expression of TGF-β1(r = -0. 981 P＜0.01) and α-SMA (r= -0.975 P＜0.01). Bailing capsule ad-ministration protected the expression of BMP-7 and reduced TGF-β1 and α-SMA expression before 12 w(P＜ 0.01 ). Conclusions Ourstudy shows an anti-fibrotic reno-protective function of Bailing capsule in rats with tubulointerstitial fibrosis via prevention of epithelial-mesenchymal transition at early stage. However, the beneficial effect lost with increasing tubulointerstitial fibrosis.

OBJECTIVETo apply needle-knife to treat lumber disc herniation (LDH) and surface electromyography were used to analyze biomechanical characteristic of patient's lumber muscle to make a comprehensive evaluation on its efficacy.

METHODSThirty patients who met the inclusive criteria were selected and treated with needle-knife, once a week for 2 weeks. Visual analogue scale (VAS), ASLR and JOA score before and after treatment were observed. Surface electromyography was applied to test the surface electromyography signals. AEMG, MFs and MPF were calculated before and after the treatment.

RESULTSAfter treatment, VAS was significantly reduced, ASLR, JOA, AEMG and MPF were obviously increased, and the absolute value of MFs was lowed (all P < 0.01).

CONCLUSIONThe needle-knife could significantly relieve lumbar muscle strength, muscle tone and muscle fatigue, improve in the imbalance of lumbar extensor muscle group, leading to the recovery of biomechanical characteristic, and the clinical efficacy is superior.

Plant samples were collected and investigated periodically. According to the growth of different parts and the characteristics of dry substance accumulation of Scrophularia ningpoensis, the development of S. ningpoensis could be divided into four stages: seeding stage, stem and leaf growth stage, expanding period of root tubers, and dry substance accumulation stage of root tuber. Leaf numbers of S. ningpoensis grew gradually from one at first to 370 at the final stage, main stem leaf were 50 pieces. Leaf size increasesed with the fastest growth at the stem and leaf growth stage, average daily increase amount was 225 cm2. By the middle of August, leaf size reached to 16,270 cm2. Leaf area indexrose sharply in the seeding stage, and remained above 8 among stem and leaf growth stage and expanding period of root tubers, and rapidly reduced to zero in the stage of dry substance accumulation of root tuber. Leaf area ratio has a tendency of obvious dropping. The net assimilation rate had a small change ranges, two small peak were seeding stage and dry substance accumulation of root tuber. The value of specific leaf area was higher in seeding stage, and in the earlier stage of dry substance accumulation of root tuber. Relative growth rate changed with large ranges, higher in seeding stage, rapid decrease in stem and leaf growth stage, rose in expanding period of root tubers, and declined again in the stage of dry substance accumulation of root tuber. Crop growth rate was higher in the first and last stages, and smaller in interim stage. The growth parameters of S. ningpoensis such as relative growth rate, net assimilation rate, leaf area index, leaf area ratio, specific leaf area, crop growth rate changed along with the growth. The rule of dry matter accumulation was as follows: the dry matter increased slowly during the seeding stage and speeded up in the middle and late stages, and in dry substance accumulation of root tuber increased slower, the growth of dry matter all appeared an "S" curve, and accorded with logistic equation. Cultivation technologies of S. ningpoensis and the relevant management methods could be established according to the growth of different parts of S. ningpoensis and the characteristics of dry substance accumulation in different stage.
