ABSTRACT
Objective To investigate changes and clinical significance of serum granulocyte-macrophage colony stimulating factor(GM-CSF),tumor necrosis factor-alpha(TNF-?),interleukin-6(IL-6)and interleukin-8(IL-8)level in patients with bee-sting poisoning.Methods One hundred and nine patients with bee-sting poisoning were also divided into slight poisoning group,moderate poisoning group,and server poisoning group and also divided into dead group and survival group according to the prognosis.Thirty healthy persons were selected as control group.GM-CSF and TNF-?were measured using radioimmunoassay,IL-6 and IL-8 was measured using enzyme linked immunoadsorbent assay(ELISA),and they were compared with control grouup.Results The levels of serum GM-CSF,TNF-?,IL-6,IL-8 in slight poisoning group were increased a little,and there were no significant difference compared with control group(P＞0. 05).The levels of serum GM-CSF,TNF-?,IL-6 and IL-8 were significantly higher in moderate poisoning group and severe poisoning group than those in the control group(P＜0.01),but the severe poisoning group were much higher than the moderate poisoning group(P＜0.01).They were significantly higher in survival group than those in dead group(P＜0.01).APACHEⅡscores were obvious correlated with the levels of serum GM-CSF,TNF-?,IL-6 and IL-8(P＜0.05 or P＜0.01). Conclusion GM-CSF,TNF-?,IL-6 and IL-8 may participate in the occurrence and progress of patients with bee-sting poisoning.Dynamic monitoring of serum GM-CSF,TNF-?,IL-6,IL-8 and APACHEⅡscores plays an important role in diagnosis of the severity of patients with bee-sting poisoning and its prognosis.The use of antagonist and inhibitor of cytokines may be helpful to treat patients with bee-sting poisoning.
ABSTRACT
Objective To study the effects and clinical significance of tea pigment on 24 hour urinary endothelin(UET) excretion in patients with early stage diabetic nephropathy.Methods 65 cases of early stage diabetic nephropathy were randomly divided into expermental group and control group.Control group was treated by routine treatment and the expermental group was treated by tea pigment,in addition to routine treatment,and was orally given tea pigment capsule 0 24g three time daily,for 8 weeks.The amounts of 24 hours UET and urinary albumin excretion rate(UAER)in the two groups patients before and after treatment were measured using radioimmunoassay method.Results The amounts of 24 hour UET in patients with diabetic nephropathy were elevated significantly as compared with those in normal control group(P0 05).After 8 week's treatment,the amounts of 24 hour UET and UAER in expermental group were significantly lower than those of control group(P
ABSTRACT
Objective To investigate the levels of serum tumor necrosis factor-alpha (TNF-?琢) and soluble tumor necrosis factor receptor (sTNF-R) and sTNF-R/TNF-?琢 ratios in patients with severe lupus nephritis (SLN) and the impact of double pulse therapy with methylprednisolone (MP) combined cytoxan (CTX). Methods Serum TNF-?琢, soluble tumor necrosis factor receptor type Ⅰ(sTNF-RⅠ) and soluble tumor necrosis factor receptor type Ⅱ (sTNF-RⅡ) levels were determined in 38 cases of SLN patients and 35 health controls by double antibody sandwich enzyme-linked immunosorbent assay (ELISA) before and after the double pulse therapy with MP and CTX. Anti-dsDNA antibody was detected by ELISA. Antinuclear antibody (ANA) was detected by indirect immunofluorescence experiments. Complement C3 and complement C4 were detected by rate nephelometry. Results The serum levels of TNF-?琢, sTNF-RⅠ, sTNF-RⅡand ratios of TNF-?琢/sTNF-RⅠ, TNF-a/sTNF-RⅡ were significantly higher in SLN patients than those in normal control group (P

ABSTRACT
Objective To investigate the changes of blood and urine endothelin levels in the aged patients with primary nephrotic syndrome(PNS) and their clinical significance. Methods The levels of blood and urine endothelin were measured by radioimmunoassay at different stages(active and alleviated stages) in 40 elderly and 40 non elderly patients with PNS and 40 elderly healthy controls(control group). The levels of endothelin in blood and urine of the aged patients with PNS, and serum creatinine(Scr), endogenous creatinine clearance rate(Ccr), 24 hour urinary protein and urinary retinal binding protein(uRBP) were determined. Results The contents of endothelin in blood and urine of the aged PNS patients in the active stage were (229?81) ng/L and (143?58)ng/24 h,which were apparently higher than those in the alleviated stage 〔(60?11) ng/L, (53?13)ng/24 h〕 and the healthy control group〔(53?9) ng/L, (50?14 ng)/24 h, P 0 05). Conclusions Endothelin may be involved in the pathogenesis of the aged PNS. The increased urine endothelin level may be an important factor in glomerulus and tubular damage in the elderly PNS patients.
