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.

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 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.

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 identify the efficacy and safety of implant vagus nerve stimulation (IVNS) for intractable epilepsy.Methods Eligible patients with intractable epilepsy during 2012-2015 were enrolled,and the information of preoperative evaluation was collected as baseline.During IVNS therapy,the process of seizures,the epileptic discharges of electroencephalogram (EEG),the complications and the changes of antiepileptic drugs or device parameters were recorded.The responder rate,the mean seizure reduction and the change of epileptic discharges were chosen as the indictors.Results Efficacy analyses were done in 33 patients,and the average age of these patients was 17.79 years.Seizure control improved over time with mean seizure reduction of 11.9％,17.3％,35.5％,38.1％,45.4％ and 50.0％,and responder rates of 18.2％(6/33),27.3％(9/33),41.4％(12/29),38.5％(10/26),7/18,and 10/17 at 1,3,6,12,24,36 months of IVNS therapy,respectively.In addition,the mean epileptic discharge reduction in EEG was 0.4％ and 13.0％,while the rate of patients who had epileptic discharge reduction of ≥50％ was 15.3％ and 23.1％ at 6,12 months of IVNS therapy,respectively.Conclusions IVNS is effective and safe.Furthermore,the efficacy of IVNS is time-dependent.

Objective To investigate the expression of cyclin dependent kinases 5(CDK5)in the temporal lobes of the epilepsy patients and to explore the possible roles of CDK5 in the pathogenesis of refractory epilepsy.Methods The brain tissues of intractable epilepsy(IE)were studied by fluorescence quantative polymerase chain reaction(FQ-PCR)for CDK5 mRNA,while immunohistochemistry and Western blot were used to study the protein expression.Nonepileptogenic control brain tissues were used for comparison.Results FQ-PCR analysis showed that the expression of CDK5 mRNA in epilepsy patients was significant higher than those in the control group.And immunohistochemistry showed that the protein mainly existed in the neuron and glial.At the 35000 relative molecular mass,Western blot could been seen that there is a limpid strap.The optical density of CDK5 in IE(temporal lobe 1.4293?0.1839,hippocampus 2.0733?0.4738)was significantly higher than that in the control(temporal lobe 0.9680?0.4147, hippocampus 1.4030?0.6160,P
