Objective To analyze the clinical features of immunoglobulin A(IgA) nephropathy(IgAN) occurring in the context of pre-vious acute glomerulonephritis.Methods The clinicopathologic features of 108 cases(77 males,31 females,aged 3.2 to 14.0 years old) of IgAN were analyzed restrospectively with the onset of acute glomerulonephritis in this department from Jan.1994 to Dec.2005.Results Of 108 cases with IgAN,10 cases were with the onset of acute glomerulonephritis. All the 10 cases presented with edema, hematuria and proteinuria.Eight cases had macroscopic hematuria, lasting for 2 days to 2 months.Four cases had recurrent macroscopic hematuria,microscopic hematuria lasting for 16 months.Urine protein qualitative +-+++ lasted for 1-8 months.Two cases had hypertension;2 cases had increasing blood uria nitrogen and serum creatinine.The increase of anti-streptolysin O(ASO) titer was detected in 5 of 9 cases.Two cases had a high titer of DNase-B antibody, and 4 cases had hypocomplementemia.Eight cases had prodromal infection with an interval time varying from 1 to 5 days.Renal biopsies revealed mesangial proliferative glomerulonephritis in 9 cases and focal segmental glomerulosclerosis in 1 case, all with mesan-gial IgA deposition.Conclusions The interval time between the prodromal infection and nephritis symptoms is mostly short in IgAN with the onset of acute glomerulonephritis, while macroscopic and microscopic hematuria remain a fairly long time or recurrently aggravate. Renal biopsy is necessary to diagnose IgAN for this kind of children.

OBJECTIVETo explore clinical efficacy of Yiguanjian Decoction (YD) combined Adefovir Dipivoxil Tablet (ADT) in treating HBeAg negative chronic viral hepatitis B (CVHB) active compensated liver cirrhosis (LC) patients.

METHODSTotally 68 HBeAg negative CVHB active compensated LC patients initially treated were assigned to the treatment group and the control group using random digit table, 34 in each group. Patients in the control group took ADT alone, 10 mg each time, once per day. Those in the treatment group additionally took YD, one dose per day. The therapeutic course for all was 48 weeks. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) were detected once in every two weeks. Hepatitis B virus (HBV)-DNA and four items of serum liver fibrosis [procollagen type I (PCN), hyaluronidase (HA), procollagen III peptide (PCIII), laminin (LN)] were detected once per every 4 weeks. Abdominal ultrasound B was performed before and after treatment. The inner diameter of the portal vein and the size of spleen were recorded. The fibrosis degree of liver was evaluated using Fibroscan. Efficacy of Chinese medicine (CM) was evaluated between the two groups before and after treatment using CM syndrome integrals. Efficacy of Western medicine (WM) was also evaluated between the two groups using Child-Pugh grading. Results Compared with before treatment in the same group, ALT and AST levels restored to normal levels, HBV-DNA turned negative (HBV-DNA < or = 1 x 10(2)) in the two groups after 48-week treatment. Besides, levels of TBil, ALB, PCIV, HA, PCIII, and LN obviously decreased (P < 0.05, P < 0.01). Results of ultrasound B showed the inner diameter of the portal vein and the size of spleen decreased. Fibroscan results showed that the elasticity value of the liver obviously decreased (P < 0.05). Besides, post-treatment levels of PCIV, HA, PCEJ, and LN, and the elasticity value of the liver decreased more obviously in the treatment group than in the control group (P < 0.01). There was no statistical difference in post-treatment levels of ALT, AST, TBil, ALB, inner diameter of the portal vein, or the size of spleen between the two groups (P > 0.05). Compared with before treatment in the same group, scores of Chinese medical syndrome and Child-Pugh scores decreased in the two groups after treatment (P < 0.05, P < 0.01). Besides, scores of Chinese medical syndrome decreased more obviously in the treatment group than in the control group (P < 0.05). The effective rate was 8824% (30/34) in the treatment group, higher than that of the control group [67.65% (23/34)] with statistical difference (P <0.05). Conclusion Combined treatment of YD and ADT could significantly improve symptoms of CM and fibrosis degree of liver of HBeAg negative CVHB active compensated LC patients.

The study aimed to investigate the effects of small ubiquitin-related modifier (SUMO) specific protease 1 (SENP1) on human PXR-mediated MDR1 transcriptional activity and mRNA expression. Empty vector and expression plasmids, including PXR, SENP1 and SENP1 mutant (SENP1m) were transiently transfected into HepG2 and LS174T cells using Lipo2000. Transcriptional activity was detected by dual luciferase reporter gene assay, and mRNA level was measured using real-time polymerase chain reaction. The results showed that SENP1 could remarkably reduce the rifampicin (RIF)-induced MDR1 reporter activity and mRNA level in hPXR over expressed HepG2 and LS174T cells (P < 0.05), whereas adding SENP1m restored the RIF-induced increases (P < 0.05). These results indicated that SENP1 could repress the RIF-induced hPXR-mediated MDR1 transcriptional activity and mRNA expression.

Objective To study the cellular immune function in children with kawasaki disease(KD).Methods T lymphocyte subcytes,levels of serum interleukin 2(IL-2) and soluble interleukin 2 receptor(sIL-2R) were determined by APAAP,ELISA met-hods,and a double-antibody “sandwich” enzyme-linked immunosorbent assay respectively in 60 cases.Results During the acute stage of KD,the percentage of CD4 +,the ratio of CD4 +/CD8 +,levels of IL-2 and sIL-2R increased markedly,while the percentage of CD3 + and CD8 + decreased significantly compared with the controls.These changes were more remarkable in patients subsequently developed coronary artery aneurysms than in those with normal appearing coronary artery.Conclusion Marked activation of cellular immune function and immune regulation disorders develop in acute stage of KD patients.

Objective To investigate the changes of thyroid hormone in peritoneal dialysis patients and analyse its impact factors, as well as the therapeutic effects of small dose of thyroxine.Methods 150 uremic patients in Hunan Provincial People’s Hospital from December 2013 to December 2014 were selected, 70 cases of uremia non-dialysis patients were divided into group A, while 80 uremia peritoneal dialysis for more than half a year were divided into group B.70 cases healthy examinees during the same period in our hospital were selected as control group ( group C ) . The total triiodothyronine (T3), total thyroxine (T4), free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH), hemoglobin (Hb), serum albumin (ALB), total cholesterol (TC), triglyceride (TG), serum creatinine (SCr), C reactive protein (CRP) and left ventricular ejection fraction ( LVEF) , subjective global assessment of nutritional act ( SGA) and other indicators were detected in three groups.Patients in group B were divided into two sub-groups according to thyroid hormone levels: B1 group had normal thyroid level while B2 abnormal.And the administration of small dose of thyroid hormone was given to patients in group B2, and the effect of the administration was evaluated by the above indexes.Results The FT3 in group A and B were significantly lower than that in group C (P<0.01).There were significant differences of levels of ALB, CRP, SGA between group B1 and group B2, and the FT3 level in group B was significant correlated with SGA, ALB, LVEF(r=0.815,P<0.001;r=0.780,P<0.001;r=0.953,P<0.001).After treated with small dose of thyroid hormone, FT3 and LVEF were improved while FT4, TSH, ALB, SGA, CRP were not improved in group B2.Conclusion The thyroid hormone level in patients with continuous ambulatory peritoneal dialysis decreases which is dominated with FT3.The decreased thyroid level is significantly correlated with nutrition ( ALB, SGA) and left ventricular function.The administration of small dose of thyroid hormone can improve the left ventricular systolic function.

The rate of corneal graft rejection is still high for high-risk keratoplasty although immune suppression drug is routinely used.The role of traditional Chinese medicine in corneal transplantation is concerned gradually.Heijingpaichitang on the prevention and treatment of rats with high-risk corneal allograft rejection needs further study.Objective This study was to investigate the inhibitory effect of heijingpaichitang on high-risk corneal transplantation immune rejection in rats.Methods Sixteen female SD rats were used as the donors and 32female Wistar rats were served as recipients.The high-risk corneal trasplantation models were established by corneal suture in 32 Wistar rats,and then homogeneity variant SD-Wistar corneal transplantation was performed.The recipients were randomized into model control group,cyclosporinc A (CsA)group,heijingpaichitang group and CsA +heijingpaichitang group.CsA,heijingpaichitang and CsA + heijingpaichitang was orally administered 4 days after operation once per day for 15 days,and normal saline solution was used at the same way in the model control group.Ocular anterior segment reaction was examined under the slit lamp and corneal opacification,edema and neovasculation were scored based on Larkin' s criteria.Rejection index of the corneal graft was recorded and the graft survival time was calculated.The pathological examination of the corneal graft was carried out in all rats,and the inflammatory cells in the corneas and CD4+ cells in the periphery blood were assayed using flow cytometry.The use of the animals complied with ARVO Statement.Results Corneal graft rejection occurred in 10 days after operation in the model control group,12-13 days in the CsA group and heijingpaichitang group and 22 days in the CsA +heijingpaichitang group.Compared with model control group,the scores of the corneal opacification,corneal edema and neovascularization were significantly lower in the CsA group,heijingpaichitang group and CsA+heijingpaichitang group (P＜0.05),and all the scores were declined in the CsA+ heijingpaichitang group compared with CsA group and heijingpaichitang group(P＜0.01),but no significant differences were seen in the scores between the CsA group and heijingpaichitang group(P＞0.05).The mean survival time of grafts was (10.38 ±1.69)days in the model control group,(22.50 ± 3.07) days in the CsA + heijingpaichitang group,with the significant difference (t =-9.790,P =0.000).The pathological examination of graft showed that the lymphocytes and new blood vessels were less in the CsA+heijingpaichitang group compared with CsA group and heijingpaichitang group 15 days after operation.Flow cytometry verified that the number of lymphocytes in graft,CD4+cells and CD4+/CD8+ in periphery blood were significantly lower in the heijingpaichitang group,CsA group and CsA+heijingpaichitang group compared with model control group (P＜0.05).Conclusions Heijingpaichitang can inhibit immune rejection to certain extent in high-risk corneal transplantation rat and has a similar effect to 0.1％ CsA.Heijingpaichitang and 0.1％ CsA have a synergistic effect.
