International Journal of Laboratory Medicine 2015;(5):594-595
Objective To investigate the levels and clinical significance of serum adiponectin(ADPN),high sensitive C-reactive protein(hs-CRP)and cystatin C(CysC)in type 2 diabetic nephropathy.Methods 75 outpatients and the inpatients with type 2 dia-betes mellitus(T2DM)in our hospital from February 2013 to May 2013 were selected and divided into three groups according to the urinary albumin excretion rate (UAER),normal-albuminuria group(UAER<30 mg/d,30 cases),micro-albuminuria group (UAER 30-300 mg/d,22 cases)and macro-albuminuria(UAER>300 mg/d,23 cases).30 subjects of healthy physical examination were selected as the control group.Urine microalbumin was measured by the immune turbidimetric method,UAER was calculated ac-cording to the 24 h urine volume,CysC and hs-CRP were measured by the immune turbidimetric method,and ADPN was measured by the enzyme linked immunosorbent assay(ELISA).The ADPN,hs-CRP and CysC levels were compared among groups.Results The ADPN level in 3 type 2 diabetic nephropathy groups was lower than that in the control group,the difference was statistically significant (P <0.05 ).With increase of UAER,serum ADPN,hs-CRP and CysC levels in 3 type 2 diabetic nephropathy groups were increased,the difference among the groups was statistically significant (P <0.05 ).The levels of serum ADPN,hs-CRP and CysC in type 2 diabetic nephropathy were positively correlated with UAER(r=0.715 6,0.476 3,0.741 3,P <0.05).Conclusion The combined detection of serum ADPN,hs-CRP and CysC has important reference value for the diagnosis and disease course of early renal damage in T2DM.

International Journal of Laboratory Medicine 2009;30(7):651-652,654
Objective To study the diagnostic value of anti-neutrophil cytoplasmic antibody (ANCA) detction in patients with systemic lupus erythematosus (SLE). Methods Indirect immunofluorescence (IIF) and Western blotting were applied to detecting the expression of sera ANCA, antinuclear antibody (ANA), anti-double-stranded DNA antibody, anti-SmithD1 antibody in 25 samples of control group and 106 samples of patients with SLE. Results ALL samples of control group showed negative; 47.2% (50/106) sera showed ANCA positive in patients with SLE,and all of them were peripheral nuclear pattern (pANCA). In ANCA positive group, the positive rate of ANA, anti-SmithD1 antibody and anti-ds-DNA antibody was respectively 100% (50/50), 82% (41/50) and 94% (47/50); in ANCA negative group, the positive rate was respectively 91.1% (51/56), 67.9% (38/56)and 50% (28/56). There were no statistical differences in positive rates of ANA and anti-SmithD1 antibody between ANCA positive and negative groups (both P>0. 05), but there was in positive rates of anti-ds-DNA antibody (P<0.01). ANCA positive rate was respectively 84.6% (44/52) and 11.1%(6/54) in active SLE group (n=52) and inactive SLE group (n=54) (P<0.01). Conclusion The determined ANCA in patients with SLE is not correlative with ANA and anti-SmithD1 antibody, but positively relates to anti-double-stranded DNA antibody. The positive rate of ANCA in patients with active lupus is significantly higher than that in non-active lupus.

Objective To observe the effects of Tianma Gouteng Yin (TGY) on the proliferation of myocardial fibroblasts of spontaneous hypertensive rat(SHR) stimulated by insulin. Methods The cardiac fibroblasts from one-day-old spontaneously hypertensive rat were primarily cultured and then sub-cultured to 3rd-6th generation,and were identified with light microscopy and immunohistochemical technique. The effect of serum containing TGY on the proliferation of cardiac fibroblasts of SHR treated with insulin was determined by MTT colorimetric assay and 3-H-TdR incorporation,and the cell cycle was analysised with flow cytometer. Results TGY inhibited the proliferation of cardiac fibroblasts induced by insulin. Insulin can stimulate the proliferation of fibroblasts by promoting the cell cycle transfer from G0/G1 period to S period and increasing the synthesis of cell DNA. Compared with the model group,the percentage of the cells at G0/G1 period was much higher,while the percentage of the cells at S period was much lower in TGY group. Conclusion TGY has the effect on inhibiting the proliferation of cardiac fibroblasts and inhibiting the cell cycle transfer from G0/G1 period to S period,which may be one of its therapeutic and protective mechanisms for hypertension and myocardial fibrosis in clinic.

Objective To investigate the effect of Candida albicans and its components on the expression level of human beta-defensin-2 mRNA (HBD-2) in keratinocytes in vitro. Methods Different components of Candida albicans were isolated by lyticase, repeated freezing and thawing, sonication, and centrifugation. The keratinocytes and HaCaT cell lines were co-cultured with Candida albicans and its cellular components for 24 h. The expression level of HBD-2 mRNA was detected by reverse-transcription polymerase chain reaction (RT-PCR). Results Low expression level of HBD-2 mRNA in the unstimulated keratinocytes and HaCaT cells was detected. The HBD-2 mRNA expression levels in the keratinocytes stimulated by Candida albicans, the extract of its cell wall, and pure mannan were significantly increased (P 0.05). Conclusions Candida albicans, the extract of cell wall of Candida albicans, and commercial mannan can increase the expression level of HBD-2 mRNA in keratinocytes.

Objective To study the prevalence of food intolerance and to explore its related factors among adult health check-up receivers.Methods A total of 863 adults who took physical examinations in our hospital from April to October 2011 were enrolled in this investigation.Height,body weight and blood pressure were measured,and serum IgG level was measured by enzyme-linked immunosorbent assay (ELISA).Results The total positive rate of food intolerance was 73%,and the leading intolerance items were crab (40.1% ),egg (29.8% ),cod fish ( 21.6% ),milk ( 20.0% ) and soybean ( 14.4% ).Females showed significantly higher prevalence of food intolerance than males.Various positive rate of milk or soybean intolerance was found in different age groups.No correlations of serum specific IgG with body mass index and systolic or diastolic blood pressure were observed.In logistic regression analysis,the odds ratio of food intolerance of women was 1.67 ( 95 % confidence interval 1.190 to 2.607 ).ConclusionsThe prevalence rate of food intolerance was high.The risk for food intolerance was significantly increased in women.Specific IgG antibody detection may help to early prevent and diagnose food intolerance-related diseases.
