Objective To study the patients' clinical characteristics and prognosis when only C3 deposition exists in endocapillary proliferative glomerulonephritis and try to understand deeply the role of C3 in kidney damage deeply. Methods The patients who were diagnosed with endocapillary proliferative glomerulonephritis but only had C3 deposited in immunofluorescence(to avoid false positive,C3≥2 ﹢ was included)were selected from Beijing Children's Hospital Affiliated to Capital Medical University during November 2010 to October 2014. Their clinical manifestations,la-boratory examinations,treatments,prognosis,and pathological changes were analyzed,and literature review was performed. Their clinical characteristics and prognosis were summarized. Results There were 11 patients diagnosed with endocapil-lary proliferative glomerulonephritis which had only C3 deposition(≥2 ﹢ ). Nine of them had onset with acute nephritis syndrome(81. 8% ),and 2 cases presented recurrent paroxysmal gross hematuria(18. 2% ). Seven cases were diagnosed with acute post streptococcal glomerulonephritis(63. 6% ). Eleven cases' clinical manifestations were relatively severe, and the complement C3 was significantly lower than the normal(100. 0% ). Their light microscope showed capillary proli-ferative glomerulonephritis,and the electron microscope showed the immune complexes were deposited in the endothelium,the epithelium or the mesangial area. The patients received corresponding treatment respectively,and all the patients had good prognosis during following up of 7 months up to 39 months. Conclusions Streptococcus infection is a common cause in endocapillary proliferative glomerulonephritis with only C3 deposition. The clinical manifestations of some children are similar to post streptococcal glomerulonephritis but relatively severe. Only deposition of C3 without IgG may be involved in another complement activation mechanism.

Objective To observe curative effect and clinical outcome in 30 recipients undergoing allogcneic peripheral blood stem cell transplantation (PBSCT) combined with bone marrow transplantation (BMT). Methods 30 patients with a median age of 32.6 years underwent allo-HSCT, of which 11 patients with AML, 14 patients with ALL, and 5 patients with CML They all have a HLA-identical sibling. PBSCswere mobilized with G-CSF. Three hundreds milliliter bone marrow blood was transplanted to the patients on the day that the PBSC was transplanted. Amended Bu/Cy was used as the conditioning regimen. MTXcombined with CsA and MMF was used as GVHD prophylaxis. Results A median number of mononuclear cells of (5.13±2.6)x10~8/kg recipient's weight was collccted from peripheral blood, and (1.3±0.6)x10~8/kgrecipient' s weight from bone marrow blood. Engraftment of neutrophils and platelets was achieved at a median of (12.1±3.25) days and (14±5.33) clays respectively. Ⅰ - Ⅱ acute GVHD occurred in 40.0 % cases,Ⅲ - Ⅳ acute GVHD occurred in 3.3 % cases, and chronic GVHD developed in 43.3 % cases. Severe cGVHD developed in 3.3% cases. The 2 years disease free survival rate (DFS) by the day of transplantation was 72.0 %. Conclusion PBSCT combined with BMT was effective to cure leukemia. The results also suggested that PBSC recipients had an lower incidence of aGVHD and cGVHD as compared with previous reports.

OBJECTIVES: The aims of this study were to update the latest data on the prevalence of hypertension (HTN) in the elderly Chinese population and to assess relationships between new anthropometric indices and HTN. METHODS: Data were obtained from the Basic Public Health Service (BPHS) survey for Jiangsu Province, China. A total of 944,760 people aged 65 years and older were included in this study. Blood pressure was measured by trained investigators. Body weight, body mass index (BMI), waist circumference (WC), waist-to-height ratio (WtHR), conicity index (COI), body roundness index (BRI), and a body shape index (ABSI) were included in the analysis as anthropometric indices. Logistic regression analysis and restricted cubic splines were used to evaluate the association of anthropometric indices with HTN. RESULTS: The prevalence of HTN among elderly residents of Jiangsu Province was 64.7% (95% confidence interval, 64.6 to 64.8). After adjusting for multiple covariates, all anthropometric indices except ABSI showed significant non-linear positive dose-response associations with HTN across sex (pnonlinear<0.001). Among participants with BMI <28 kg/m2, abnormal weight, WC, WtHR, BRI, COI, and ABSI were positively associated with HTN. CONCLUSIONS The prevalence of HTN in the elderly in Jiangsu Province is gradually increasing. It is necessary to consider the combination of ABSI and COI with BMI for screening elderly individuals for HTN in follow-up prospective studies.

Objective To summarize the clinical data of atypical hemolytic uremic syndrome (aHUS) and analyze the treatment and prognosis.Methods A prospective cohort study was conducted on 66 cases in Beijing Children's Hospital affiliated to Capital Medical University from January 2011 to December 2017.The children were divided into positive and negative auto-antibody groups according to the results of anti-factor H autoantibody test.The clinical characteristics,treatment plan and prognosis of the two groups were compared.Results Among the 66 children who met the inclusion criteria,there were 43 cases (65.2％) in the positive group,with an average onset age of (8.0±2.9) years.There were 23 eases (34.8％) in the negative group,with an average onset age of (3.0± 2.6) years.On the basis of plasma treatment,in the positive group,the usage rate of hormone was 83.3％ (35/42) and the usage rate of immunosuppressive agents was 42.9％(18/42),while in the negative group,the rates were 63.6％(14/22) and 13.6％(3/22) respectively.The average follow-up time was 19.3 months.One child in each group was lost to follow-up.In the positive group,8 cases recurred (19.0％)and the average recurrence interval time was 16.1 months.In the negative group,7 cases recurred (31.8％) and the average recurrence interval time was 9.3 months.And the recurrent interval time in the positive group was more longer than the negative group (P ＜ 0.05).A total of 85.9％(55/64) children had complete hemolysis control and complete recovery of renal function,in which the positive group was 85.7％(36/42) and negative group was 86.4％(19/22).However,7.8％(5/64) children had abnormal renal function,in which the positive group was 9.5％(4/42) and the negative group was 4.5％(1/22).And 4.7％(3/64) children died,in which the positive group was 2.4％(1/42) and the negative group was 9.1％ (2/22).The one left (1.6％) showed dialysis dependence,which was positive for the auto-antibody.Multifactor Cox regression analysis showed that the age of less than 3 years old was the risk factor of poor prognosis (HR=4.651,95％CI 0.988-21.898,P=0.047).Conclusions The positive proportion of anti-factor H autoantibody in children with aHUS is high.The age of these children is older.Individualized therapy based on anti-factor H autoantibody and immunosuppressive therapy is of great significance for disease remission,preventing recurrence and improving the prognosis.Age less than 3 years old is the risk factor for poor prognosis.

Objective: To determine the effects of ω-3 polyunsaturated fatty acids from different sources on glucolipid metabolism in type 2 diabetic patients with dyslipidemia. Methods: We recruited participants from the diabetes specialist clinic at the Guanlin hospital in Yixing city, Jiangsu Province from February 2017 to March 2017. A total of 180 subjects were randomly assigned to 3 g/day fish oil (FO), perilla oil (PO), or fish oil mixed with linseed oil (FLO) for 6 months. The basic conditions and fasting venous blood sample were obtained from each study subject at baseline, after 6 months of intervention. Serum glucose and lipid metabolism were investigated. Results: A total of 156 subjects aged (62.6±8.6) years completed the final follow-up after 6 months (FO,54 subjects; PO,52 subjects; FLO,50 subjects). Among them,59 patients (37.8%) were male. Serum glucose, glycated hemoglobin, C peptide, insulin and homeostasis model assessment-insulin resistance were not significantly different among the three groups after 6 months. Serum triglyceride decreased, whereas high-density lipoprotein cholesterol increased in FO [1.33 (1.05,1.93) mmol/L, (1.36±0.29) mmol/L, respectively] compared with PO [1.71 (1.23, 2.17) mmol/L, (1.23±0.22) mmol/L, respectively] and FLO [1.51 (1.12, 2.22) mmol/L, (1.29±0.30) mmol/L, respectively] (P<0.05). Serum low-density lipoprotein cholesterol and apolipoprotein B decreased in PO [(2.60±0.57) mmol/L,(0.96±0.23) g/L, respectively] compared with FO [(2.89±0.76) mmol/L, (1.07±0.30) g/L, respectively] (P<0.05). Serum lipoprotein(a) decreased in FLO [130.7 (63.3,270.6) mg/L] compared with FO [137.4 (58.7,333.2) mg/L] (P<0.05). Serum free fatty acid decreased in FLO [(0.43±0.15) mmol/L] compared with PO [(0.53±0.22) mmol/L] (P<0.05). Conclusion The effects of ω-3 PUFA from different sources on glucose metabolism in type 2 diabetic patients with dyslipidemia are similar. Each of them has a good application prospect in improving lipid metabolism.

BACKGROUNDAn zidovudine (AZT)-substitution regimen containing 24-week stavudine (d4T) followed by long-term AZT for HIV therapy is potential to trade off short-term AZT-related anemia and long-term risks associated with d4T in resource-limited settings. However, evidence is scarce. This study aims to assess the efficacy and safety of AZT-substitution regimen, aiming to find a regimen with better efficacy, less adverse events, and more affordability in resource-limited settings.

METHODSThis prospective, multicenter study enrolled 499 (190 on d4T regimen, 172 on AZT regimen, and 137 on AZT-substitution regimen) HIV-1-infected subjects who initiated combined antiretroviral therapy and attended follow-up visits over 96 weeks from 2009 to 2011. Lamivudine (3TC) and either nevirapine (NVP) or efavirenz (EFV) were the other two drugs in the antiretroviral regimens. Virologic and immunologic responses and adverse events were monitored at baseline and at weeks 4, 12, 24, 36, 48, 60, 72, 84, and 96.

RESULTSIn terms of hematological adverse effects, AZT-substitution group had similar safety profiles to d4T group and was superior to AZT group. In comparison with AZT-substitution group, AZT group was associated with higher risk of developing anemia (adjusted hazard ratio (aHR) for anemia ≥ grade II, 8.44, 95% CI 1.81-39.46) and neutropenia (aHR for neutropenia ≥ grade II, 1.86, 95% CI 1.19-2.93). The prevalence of lipodystrophy in d4T group was 19.5%, while that in AZT-substitution group was zero. As to antiretroviral efficacy, these three groups showed no differences.

CONCLUSIONAZT-substitution regimen provides a relatively safe and effective first-line antiretroviral strategy in resource-limited settings.
