Objective: To observe the efficacy of acupoint sticking with Jianpi Tongjing Zhitong ointment in the treatment of functional dyspepsia due to liver-qi stagnation and spleen deficiency and its effect on serum 5-hydroxytryptamine (5-HT) and ghrelin contents. Methods: One hundred patients with functional dyspepsia due to liver-qi stagnation and spleen deficiency were divided into a treatment group and a control group by the random number table method, with 50 cases in each group. The treatment group received acupoint sticking with Jianpi Tongjing Zhitong ointment and the control group was treated with mosapride citrate orally. Patients were treated for 4 weeks as a course. The therapeutic efficacy was compared after one-course treatment and the differences in gastric emptying rate, and serum 5-HT and ghrelin contents between groups were compared before and after treatment. Results: The total effective rate was 79.6％ in the control group and 89.4％ in the treatment group, showing significantly different between groups (P<0.05). After treatment, the gastric emptying rate and serum ghrelin content of the two groups increased significantly, and the serum 5-HT content decreased significantly, the intra-group differences were significant (all P<0.01). After treatment, the gastric emptying rate and serum ghrelin content were significantly higher in the treatment group than those in the control group, while the serum 5-HT was significant lower in the treatment group, the inter-group differences were significant (all P<0.05). A negative correlation (r=-0.59) was observed between serum 5-HT content and gastric emptying rate, and a positive correlation (r=0.64) was observed between serum ghrelin content and gastric emptying rate, showing statistical significance (all P<0.01). Conclusion: Acupoint sticking with Jianpi Tongjing Zhitong ointment has a remarkable clinical efficacy in treating patients with functional dyspepsia due to liver-qi stagnation and spleen deficiency and is able to influence the secretion of serum 5-HT and ghrelin. Improving the gastrointestinal motility through the regulation of related brain-gut peptides is suggested as an underlying mechanism for this therapy.

Actin cytoskeleton in podocyte is a complicated network structure,and the stability of this structure depend on many proteins which located in slit diaphragm,the apical membrane domain and the basal membrane domain with the stimulus of mechanical stress,the actin cytoskeleton can be adaptive regulated to maintain the normal function of glomerulus,and several signal pathways involve in the process,such as RhoA/Rho kinase signal pathway and TRPC6.

Objective Insulin autoantibody (IAA) is known to exist in sera of type 1 diabetes mellitus (T1DM) patients and pre-T1DM individuals. The aim of this study was to establish a novel microtiter plate radioimmunoassay (RIA) for IAA and evaluate its clinical value. Methods Diluted 125Ⅰ-insulin was mixed with 5 ul serum samples in a 96-well microtiter plate and then incubated for 72 h on an orbital plate shaker (4℃). The immunocomplexes were transferred to another protein a coated Millipore plate, and then the plate was washed with Tri-Buffered Saline Tween-20 (TBT) buffer. Counts per minute (CPM) was measured with liquid scintillation and luminescence counter. The positive cut-off point of IAA index was defined as ≥0.06 based on the 99-percentile of the distribution in 317 healthy individuals. The specificity and sensitivity of the assay were calculated from the samples provided by the fourth Diabetes Autoantibodies Standardization Program (DASP 2005). The IAA levels were determined in 71 T1 DM and 551 newly diagnosed type 2 diabetes (T2DM) patients, and 317 healthy controls. The t test, non-parametric test, x2 test and linear correlation analysis were performed on the data using SPSS 11.5 software. The concordance rate was estimated with Kappa value. Results (1) The optimized testing condition was described as 2×104 CPM of 125Ⅰ-insulin, 5 ul serum sample and slowly horizontal shaking for 72 h. (2) The intra-assay CV was 4.8%-8.9% and inter-assay CV was 6.4%-10.5%. Based on DASP 2005 samples, the specificity and sensitivity of the assay were 97% (97/100) and 50% (25/50), respectively. Ninety-six serum samples with different IAA levels were selected and tested to compare between our new method and a domestic IAA RIA kit. The results showed that the IAA indices from the two methods were positively correlated (r= 0.678, P<0.001). The concordance rate was 72.9 %(Kappa value=0.402). There were 25 samples with discordant results, which were positive for IAA titer using the corresponding microtiter plate RIA but negative using the novel RIA kit. (3) In TIDM group the positive rate of IAA was 19.7% (16/71), higher than the healthy controls (0.9%, x2=54.36, P<0.001). The subgroup of T1DM children (with 0-9 years) showed the highest IAA positive rate (55.6% ,x2=4.85, P<0.05). In T2DM group the frequency of IAA was 1.5% (8/551), which had no significant difference comparing with that of healthy controls (x2= 0.95, P >0.05). Conclusions Our proposed microtiter plate RIA method for IAA is highly sensitive and specific, likely to be feasible for clinical application. The frequency of IAA is high in children with T1DM.

Objective To detect the levels of transforming growth factor-?_1(TGF-?_1) in plasma,serum and urinary of children with Immunoglobulin A glomerulonephritis(IgAGN) and mesangial proliferate glomerulonephritis(MsPGN) and explore the different effects of TGF-?_1 in the two diseases.Methods The plasma,serum and urinary TGF-?_1 levels were measured in 24 children with IgAGN,and 30 children with MsPGN and 30 healthy controls by enzyme-linked immunosorbent assay(ELISA).Results The TGF-?_1 levels in plasma,serum and urinary samples of IgAGN group were increased.The TGF-?_1 levels of IgAGN were significantly higher than those of MsPGN and heathy controls(P(0.05)).Conclusion It is showed that TGF-?_1 plays a diffenent role in IgAGN and MsPGN.

Objective To study the possibility of medication treatment in Alport′s syndrome(AS).Methods Two boys with AS,received cyclosporin A(CyA) in combination with angiotensin-converting enzyme inhibitor(ACEI) or only ACEI,which lasted 22 months and 20 months,respectively.Results After the treatments with the medication,there was obvious effectiveness in the 2 patients with relieved symptom and almost normal serum standard,especially the permanent and obvious recession of proteinuria.There was no side effects of medication during the treatment.Conclusion Patients with AS can be treated with CyA and ACEI,with symptomatic recession,as well as suspend the progression of pathology of kidney.

Objective To investigate the relationship between the clinical character and pathological variants as well as response to treatment of focal segmental glomerulosclerosis(FSGS) in children.Methods The clinical feature, laboratory data and histological variants of 48 children with idiopathic FSGS proven by renal biopsy were studied retrospectively. Among them,34 were boys;14 cases were girls. The age ranged from 1.75 to 16.0 years.Results Of 48 children with FSGS,nephrotic syndrome in 32(66.7%)was the predominant clinical manifestation. The pathological classification included FSGS not otherwise specified(NOS) in 29 cases(60.42%), perihilar variant in 14 cases(29.17%), tip variant 3 cases(6.25%), cellualr variant 2 cases(4.17%)and no collapsing variant. The different pathological variants had similar rate of segmental sclerosis glomeruli; perihilar variant had a higher global sclerosis glomeruli than FSGS NOS and other variants and there was a statistical significance(P 0.05).Vascular lesions were rarely seen in all kinds of histological variants of children.Conclusions Hypertension and renal insufficiency are less frequently seen in children FSGS, isolated hematuria as unique clinic presentation is common in FSGS. All pathological variants have tubular-interstitial lesions, but vascular lesions are rarely seen. Most FSGS children with nephrotic syndrome are sensitive to steroid at initial stage, and easy to develop frequent relapse gradually, immunosuppressive agent may be helpful to elevate remission rate.

Objective To explore the expression and mutual relationship between transforming growth factor-?(TGF-?) and hepatocyte growth factor(HGF) in children's renal tissues,as well as the effect of the 2 indexes on the renal pathological change.Methods According to the severity of renal pathological change under light microscope,61 cases were divided into 3 groups:named control group(26 cases,clinically diagnosed as thin basement membrane nephropathy),test group Ⅰ [22 cases,clinically diagnosed as less evident focal segmental glomerulosclerosi(FSGS) nephropathy] and test group Ⅱ(13 cases,clinically diagnosed as evident FSGS nephropathy).Immunity class test(SP method:streptavidinbiotin peroxidase method) was used to detect the representation of HGF and TGF-?.Semi-quantitative analysis had been carried out in all cases.Film reading of cell was viewed by Olympus microscope,brown yellow from cytoplase as the positive signal,10 high power microscope visions were randomly selected from renal glomerali area and 10 from renal interstitium area.Medical image analysis software was used to determine the masculine area of HGF or TGF-? and image intensity;then the immunity class index was defined as masculine area ? image intensity.Results 1.HGF and TGF-? existed in all renal tissues;2.Expressions of HGF and TGF-? increased obviously along with FSGS pathology alteration(Pa

Objective To observe the time-dependent changes of astrocytes and microvessels in the ischemic core and surrounding areas.Methods Glial fibrillary acidic protein (GFAP)was measured by HE,and CD31 by immunohistochemistry as markers in post-mortem specimens from ten patients,who died of cerebral infarction.Results Each section of the infarcted brains was divided into four areas (the area 0-3).GFAP expressed a little in area 0 and 1,increased in a time-dependent manner in area 2 and 3;CD31 die not expressed in area 0,expressed a little in the area 1,and increased in area 2 and 3 continuously.Conclusions The proliferation of astrocytes and microvessels may play a significant role in the process of restoration after cerebral infarction.

Objective To study the pathological characteristics of skeletal muscle in patients with polymyalgia rheumatica(PMR).Methods Thirteen patients were diagnosed PMR according to the diagnostic criteria described by Bird in 1979.The onset of disease was between 49-78 years of age (median 60.3 years).All of them showed continuous symmetric myalgia with markedly elevated erythrocyte sedimentation rate(ESR).Five patients had mild fever and 8 patients had elevated C-reactive protein(CRP).Electromyogram(EMG)showed myogenic pattern in 2 patients.Only 1 patient showed anemia and 2 patients had mild elevated creatinine phosphokinase.None of them showed evidence of temporal arteritis.Biceps brachii muscle biopsies were performed in all patients before corticosteroid therapy.Results The typeⅡmuscle fiber atrophy was observed in all patients.Moth-eaten changes appeared in 8 cases,increased intramuscular lipid drops in 8 cases and ragged red fibers(RRF)in 3 cases of them.After steroid therapy,all patients showed improvement of myalgia and normal ESR as well as CRP.Conclusions The main symptoms of the patients are myalgia and abnormal ESR.Some patients have high level of CRP and abnormal EMG.Anemia and temporal arteritis are less frequent.The main myopathological changes were typeⅡmuscle fiber atrophy.Some patients have moth-eaten changes.More lipid drops and RRF indicate abnormal metabolism of skeletal muscle.
