Objective To observe the effect of ciclosporin(CsA) treatment on children with refractory nephrotic syndrome(NS).Met-hods Combination treatment of CsA[3-5 mg/(kg?d)] and prednisone were given 55 cases with refractory NS,in which including steroid-dependent NS(SDNS) 3 cases,steroid-resistant NS(SRNS) 22 cases,frequent-relapses NS(FRNS) 30 cases.Concentration of CsA was maintained 100-200 ng/L.Course of treatment was 10 months,the dose was tapered gradually in 4 months.Scr,BUN,Alb,ALT,Ccr,Chol,24 hours urine protein quantitation was measured before and after CsA treatment.Side effect of CsA was observed at the same time.SPSS 13.0 software was used to analyze the data.Results Forty-one cases(74.5%) were complete remission,6 cases(10.9%) were partial remission,total effective rate was 85.5%.Remission rate was 97.6% in simple type NS,50.0% in nephritis type NS,100% in SDNS and FRNS groups,63.6% in SRNS group.In group minimal change disease(MCD),the remission rate was 100.0%,while 60.0% in group mesangial prolife-rative glomerulonephritis(MsPGN),and 42.9% in group focal segmental glomerulosclerosis(FSGS).Fifteen cases(31.9%) relapsed when the dose of CsA was tapering.The adverse effects included hairiness(55 cases),gum hypertrophy(16 cases),hypertension(9 cases),gastroi-ntestinal tract reaction(8 cases),but no obvious nephric adverse effects were observed during the treatment process.Conclusion CsA is safe and effective on refractory NS children,especially to those with SDNS,FRNS and MCD.

This paper, from the aspects of neuroendocrine, emotion, learning etc, analyzed comprehensively the characteristics of the influence of prenatal stress (PS) on offspring, including intensity of PS, timing of exposure and individual differences. Despite the variety in methodology, most studies on it indicate that the prenatal stressful events lead to offspring's increased plasma glucocorticoid (GC) level, more depressed-related behaviors and impaired learning abilities. Although mechanism of prenatal stress is still unclear, most studies show that it is concerned with hypothalamio-pituitary-adneral (HPA) axis,dopaminergic (DA-ergic) system, neuropeptide Y (NPY)and serotoninergic (5-HT ergic) system. Moreover, further studies are proposed to pay more attention to the relationship and interaction of various related substances.

To study the role of anti- C. albicans IgY and serum in protection of C. albicans infection of several animal models. To develop three animal models of C. albicans infection: a burned rat model of C. albicans infection, a mouse model of vaginal candiasis and a immunosuppression mouse model of C. albicans infection. And we compared the contribution of anti- C. albicans IgY and serum to the clearance of the C. albicans in three animal models of C. albicans infection. Anti- C. albicans IgY can protect against C. albicans infection in a burned rat model of C. albicans infection and a mouse model of vaginal candidiasis. The serum can effectively protect the mice from disseminated candidiasis in a immunosuppression mouse model. Humoral immunity component involving anti- C. albicans IgY and serum protect against C. albicans infection in a burned rat model of C. albicans infection ,a mouse model of vaginal candidiasis and a immunosuppression mouse model of C. albicans infection.

To propose the new concept of multidimensional omics, and define that the multidimensional omics is a proper method for studying the material base and mechanism of traditional Chinese medicine (TCM) compounds. Zhuanggu Zhitong capsule was taken for example to study its effect against experimental postmenopausal osteoporosis. From the perspective of chemi-omics, genomics and proteomics of TCM, it systematically interpreted the efficacious materials and mechanisms of Zhuanggu Zhitong capsule in preventing and treating experimental postmenopausal osteoporosis, while taking the lead in designing a three dimensional form to intuitively exhibit the results of the multidimensional omics study. This study provides a new idea and solution for studies on the efficacious materials and mechanisms of TCM compounds.

AIM:To compare the clinical effect of 23G and 25G+ vitrectomy for treatment of proliferative diabetic retinopathy (PDR).METHODS: A total of 128 PDR patients (195 eyes) requiring vitrectomy in our hospital from November 2013 to May 2016 were randomly divided into 25G+ group and 23G group, 64 cases (97 eyes) in 25G+ group and 64 cases (98 eyes) in 23G group.In 25G+ group, patients were treated by 25G+ vitrectomy.In 23G group, patients were treated by 23G vitrectomy.The visual acuity, as well as intraocular pressure (IOP), iatrogenic injury and complications in two groups were recorded before and 1d, 1wk, 1mo after treatment.The operation time was compared between two groups.RESULTS: The operation time in 25G+ group was lower than that in 23G group (P<0.05).The postoperative visual acuity at 1mo of two groups were improved compared with before surgery (P<0.01).However, visual acuity between two groups in the same period had no significant difference (P>0.05).IOP in 25G+ group before surgery had no significant difference compared with those after surgery at 1d,1wk, and 1mo(P>0.05), which it was the same in 23G group.IOP of two groups in the same period had no significant difference (P>0.05).The incidence rate of iatrogenic injury in 25G+ group was 4.1%, which was significant lower than that of 23G group (13.3%) (P<0.05).The incidence rate of complication in 25G+ group was 3.1%, which was significant lower than that of 23G group (11.2%) (P<0.05).CONCLUSION: Both 23G and 25G+ vitrectomy are safe and effective treatment for PDR.However, 25G+ vitrectomy is the better choice for PDR for the shorter operation time, lower incidence rate of iatrogenic injury and fewer surgical complications.

Objective Analysis the epidemiological characteristics on rabies cases occurred in Guangxi from 2004 to 2008 and summarize the result of healthy-dog infection rabies virus investigation from 2006 to 2008.Exploring the high-occurrence and correlated factors on rabies in Guangxi.Methods Data collected from the National Disease Surveillance System and the National Active Surveillance System for Rabies from 2004 to 2008 and Data of healthy-dog infection rabies virus investigation from 2006 to 2008 were analyzed.Results The total rabies cases were 2463 in Guangxi from 2004-2008 and average incidence rate was 0.98 per 100 thousand per year.There were 95 counties had rabies case reported,anyway more than 10 cases occurred county number was declined while less than 5 cases rose year by year.The rabies case incidence area was expanded and the cases in middle and west area of Guangxi rose significantly.Rabies cases were reported whole year and no seasonal peak.Human rabies eases mainly were farmers,students and children.Yanger than 20 years old and elder 40 years old were the highest age groups in the population of the investigation,83.79% cases were attacked by dogs.78.5% cases classification category Ⅲ.83.17% cases had exposed on the upper and lower limbs,10.56% exposed to the head,face or neck.But 67.88% cases did not received any PEP and only 18.31% cases vaccinated and 3.63% category Ⅲ exposure cases combined administration of RIG.The incubation median was 60 days.The rabies virus infection rate among randomly collection healthy-dog brain samples from 2006 to 2008 was 1.92%,0.93% and 0.89%.Conclusion Unsuccessful and inadequate PEP of patients were the main factors leading to the high-occurrence of human rabies in Guangxi.And there axe a lot of infection rabies virus healthy-dogs alive in Guangxi also as a high-occurrence factor.

OBJECTIVETo evaluate the efficacy and safety of cyclosporine A(CsA) in the treatment of refractory nephrotic syndrome (RNS) in children.

METHODSThe Cochrane library, PubMed, EMBASE, CBMdisk, CNKI and VIP were searched from the time when the databases were established to December 31, 2008. Reports on RCTs on treating RNS in children with CsA were collected. Data were extracted and assessed independently by three reviewers. The methodological quality of included RCTs was assessed by the revised Jadad-scale (including randomization, allocation concealment, blinding method and withdrawal). Meta-analysis of homogenous RCTs was managed by using RevMan4.2.3.

RESULTNine RCTs involving 293 participants were included. Six RCTs were assessed as high-quality studies with scores from 4 to 7 and 3 RCTs were assessed as low-quality studies with scores from 1 to 3. Sub-category meta-analysis was based on different clinical types and interventions of RNS in children. Meta-analysis based on included RCTs showed the following results. (1) In children with steroid-dependent or frequent relapse nephrotic syndrome: the short-term efficacy of CsA plus prednisone was better than that of prednisone alone [OR 0.14, 95% CI (0.03, 0.71)]; the short-term efficacy of CsA, cyclophosphamide (CTX) and mycophenolate mofetil had no significant differences, but compared with chlorambucil, CsA had a worse short-term efficacy [OR 6.93, 95% CI (1.53, 31.38)] and a higher relapse rate [OR 0.06, 95% CI (0.01, 0.58)]; maintaining a blood level of CsA between 60 and 80 microg/L during remission period could reduce the long term relapse rate [OR 6.43, 95% CI (1.21, 34.19)]; the incidence of end-stage renal disease (ESRD) or mortality was zero in both groups. (2) In children with steroid-resistant nephrotic syndrome, the short-term efficacy of CsA was better than that of placebo or supportive treatment and CTX, OR and 95% CI were 0.15 (0.02, 0.96) and 0.41 (0.03, 5.00), respectively, but no significant differences were found in the relapse rate and the incidence of ESRD or mortality. (3) Side effects of CsA: the incidence of nephrotoxicity, hypertrichosis and gum hypertrophy was higher in the CsA group than in that of control group, OR and 95% CI were 0.19 (0.05, 0.79), 0.06 (0.02, 0.19), 0.05 (0.02, 0.18), respectively, but no significant differences were found in the incidence of hypertension and liver toxicity.

CONCLUSIONSAvailable evidence showed that CsA could improve short term efficacy in RNS in children, but could not improve long term and endpoint efficacy, therefore CsA could be one of the ideal second-line drugs for RNS in children. There was a trend that the effect of CsA on steroid-dependent or frequent relapse nephrotic syndrome was superior to that on steroid-resistant nephrotic syndrome.

OBJECTIVETo study the clinical and pathological features of Denys-Drash syndrome (DDS).

METHODThree DDS cases who were treated in our department from December 2009 to June 2011 were subjected to this study by reviewing of literature.

RESULTBoth case 1 and case 2 were female, with karyotype 46, XX. Case 3 was male with bilateral cryptorchidism. The ages of nephropathy onset of the three cases were 1 year and 9 months, 2 years and 8 moths, and 3 months respectively. Proteinuria in case 2 and case 3 were evidenced to be resistant to steroid. Case 1 was partially responsive to tacrolimus, plasma albumin and cholesterol were improved, although proteinuria was persistent after Tacrolimus was administered. Remission was achieved in case 2 after administration of cyclosporine A and later tacrolimus, and her renal function remains normal till present (4 years and 9 months). Residue renal histology revealed diffused mesangial sclerosis (DMS) in all three patients. All of the three patients had developed right unilateral Wilms tumor. A novel WT1 missense mutation exon 9 c.1213C > G was detected in case 1. WT1 exon 9 c.1168C > T nonsense mutation and exon 8 c.1130A > T missense mutation were detected in case 2 and case 3, respectively.

CONCLUSIONThe clinical manifestation of nephropathy in DDS is variable. The majority present with early onset nephropathy and reach renal failure before the age of 4 years. But in a few patients, nephropathy can also be present much later and progress slowly. Proteinuria in DDS is resistant to steroid but is responsive to calcineurin inhibitors, including Cyclosporine A. The effectiveness of tacrolimus was also observed in this study. DDS is evidently caused by WT1 mutation. DMS is the characteristic renal pathological change in DDS.
