Objective To explore the clinical and pathological features of primary IgA nephrology in patients of different gender.Methods The clinical manifestations,laboratory examination and renal pathology results were compared in 192 IgA nephrology patients.Results Not only the onset age of the male patients was older than that of the female ones (P<0 .05 ),but also the course of disease before the kidney biopsy of male patients was longer than that of the female ones (P<0.05).Besides,the proportion of edema in the male patients was lower (P<0.05).The mean arterial pressure,hemoglobin and 24 h urine protein levels were higher in the male patients at the time of kidney biopsy.Besides,the proportions of high blood pressure,hyperuricemia and hypertriglyceridemia were all higher in the male patients.Furthermore,eGFR of the male patients was lower than that of the female ones (P<0 .05 ).There was a significant difference in the gender distribution of clinical and pathological types (χ2=12.666,P<0.05),and the male and female patients also significantly differed in the 24 h urine protein and CKD grouping (Z=-3.118,Z=-3.246,P<0.05).However,there was no significant sex difference in Lee pathology grading or immunofluorescence type (Z=-1.881,χ2 =-0.187,P>0.05 ).Patients of different gender significantly differed in the renal-interstitial lesions grading (Z=-3.0432,P<0.05);to be more specific,the scores of glomerulosclerosis and renal tubule interstitia were higher in the male patients (P<0.05).Conclusion Patients of different gender differ in the clinical and pathological features of primary IgA nephrology.And clinical pathology of male patients is worse than that of female ones.

Objective To investigate the levels and clinical value of the peripheral blood CD154 and CD4+CD25+FoxP3+ regulatory T cells in patients with ankylosing spondylitis (AS).Methods 20 patients with AS and 20 healthy donors were studied.Flow cytometry was used to analyze the levels of the peripheral blood CD154,CD4+CD25+FoxP3+ regulatory T cells and HLA-B27.And T-test,Spearman correlation analysis were used in statistical analysis.Results The level of the peripheral blood CD154 was significantly higher in AS patients than that in normal controls [(4.38 ± 1.64) ％ vs.(1.92 ± 1.13) ％ (t =5.836,P ＜ 0.05)],and the level of the peripheral blood CD4+CD25+FoxP3+ regulatory T cells was lower in AS patients than that in normal controls [(3.87 ± 1.11) ％ vs.(6.30 ± 1.46) ％ (t =6.254,P ＜ 0.05)].There was negative correlation between the peripheral blood CD154 and CD4+CD25+FoxP3+ regulatory T cells in AS (r =-0.539,P ＜ 0.05).No relationship of the peripheral blood CD154,CD4+CD25+FoxP3+ regulatory T cells with laboratory parameters were found in AS.Conclusion The levels of the peripheral blood CD154 and CD4+CD225+FoxP3+ regulatory T cells in AS are abnormal,and may be involved in the immunological pathogenesis of AS.

Objective To analyze the structures and molecular weight distributions of the capsular polysaccharides from 6 serotypes of pneumococcus .Methods The structures of pneumococcal capsular pol-ysaccharides of 6 serotypes were analyzed by 1 H nuclear magnetic resonance ( NMR) .Chemical shifts of all characteristic protons were investigated to analyze polysaccharide integrity and inter -assay consistency .High performance size exclusion chromatography-multi angle laser light scattering ( HPSEC-MALLS) was used to measure the molecular weights .Results The chemical shifts of all characteristic protons of the pneumococ-cal capsular polysaccharides of 6 serotypes were consistent with the standard chemical shift .The weight-aver-age molecular mass of the pneumococcal capsular polysaccharides ranged from 7.182×104 g/mol(for serotype 19A) to 1.273×106 g/mol(for serotype 9V)examined by HPSEC-MALLS.Conclusion The structures and molecular weight distributions of pneumococcal capsular polysaccharides could be rapidly and effectively ana -lyzed by 1 H NMR and HPSEC-MALLS.Moreover, C-PS and acetate contained in capsular polysaccharides could also be detected .HPSEC-MALLS is an applicable method for the quantitative analysis of molar mass distributions in different serotypes of pneumococcal capsular polysaccharides . Although 1 H NMR and HPSEC-MALLS have been accepted as the quality control measurements by WHO , to use them as the re-placements of the traditional QC method still needs further investigation .

Objective To investigate the molecular size distribution and the structure of group B me-ningococcal capsular polysaccharides for the development of vaccines .Methods The molecular size distribution of group B meningococcal capsular polysaccharides was analyzed by chromatography on a Sepharose CL -4B col-umn.The molecular weight of repeat units were measured by matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS).The structural characteristics of group B meningococcal capsular polysaccharides were analyzed by nuclear magnetic resonance ( NMR) based on the chemical shift of all charac-teristic protons by using group C meningococcal capsular polysaccharides and sialic acid as the controls .Results The KD value of group B meningococcal capsular polysaccharides extracted from 15 strains were ranged from 0.60 to 0.76.The molecular weight of repeat units was 284, which was identical to the theoretical value .The group B meningococcal capsular polysaccharides were 2→8 linked homopolymers of sialic acid lacking O-acetyl groups.Conclusion The group B meningococcal capsular polysaccharides had lower molecular weights , which might result in their poor immunogenicity .The structure of group B meningococcal capsular polysaccharides could be quickly and accurately analyzed by NMR technology .

OBJECTIVETo study the relationship between the TCM Syndrome Differentiation-types of congestive heart failure (CHF) and thyroid hormones, including triiodothyronine (T3), thyroxine (T4) and thyroid stimulating hormone (TSH), and atrial natriuretic peptide (ANP), as well as cardiac function parameters, including left ventricular ejection fraction (LVEF), mean velocity of circumferentid fiber shortening (mVcf) and A peak/E peak (A/E).

METHODSOne hundred patients with CHF were divided into 4 Syndrome Differentiation-type groups, their cardiac function parameters, ANP and thyroid hormones were determined and compared with those in the 23 subjects in the control group.

RESULTSIn CHF patients with edema and blood stasis Syndrome type, the level of plasma ANP was significantly higher than that in the control group (P < 0.05); level of T3 was significantly lower than that in the control group and in CHF patients of other three (Xin-qi deficiency, Yin-deficiency and blood stasis) Syndrome groups (P < 0.01, P < 0.01, P < 0.05 and P < 0.01); levels of LVEF and mVcf were significantly lower than those in the other three Syndrome groups (all P < 0.01). Level of T4 in other three Syndrome groups significantly increased than that in the edema and blood stasis Syndrome type. A/E value showed a higher level in patients of all TCM type than that in the control (P < 0.01). Correlation analysis showed that T3 was positively correlated with LVEF and T4 (r = 0.200, P < 0.05, and r = 0.293, P < 0.01), and negatively correlated with ANP (r = -0.263, P < 0.01); T4 was negatively correlated with A/E (r = -0.226, P < 0.05).

CONCLUSIONThe lowering of T3 and T4 and increasing of ANP may be one of the important reasons for lowering of LVEF in CHF patients with edema and blood stasis Syndrome-type. The decrease of T4 may be one of the important reasons for elevation of A/E and aggravation of left ventricular diastolic dysfunction in CHF patients of all the 4 TCM Syndrome-types.
