Pd nanoparticles (Pd NPs) were electrodeposited on the glassy carbon electrode (GCE). Then, Pd NPs/GCE was further inserted into H2 SO4 solution to polarize for 5 min to absorb a certain amount of active hydrogen. Then, the electrode was quickly inserted to HAuCl4 solution for 15 min. AuNPs were deposited spontaneously on the surface of Pd NPs due to the reduction of active hydrogen. As a result, Pd-AuNPs were modified on the surface of GCE. Next, aptamer I of thrombin was immobilized on Pd-Au nanoparticles. In the presence of thrombin, it bound with the aptamer immobilized on Pd-Au nanoparticles and thus the formed complex obstructed the catalysis of Pd-Au nanoparticles to H2 O2 . Hence, the reduction current of H2 O2 decreased with the increase of thrombin concentration. The aptamer sensor had a good linear relationship with the concentration of thrombin in the range of 2. 98-297 nmol/L with a detection limit of 0. 98 nmol/L.

Objective To investigate the association of serum adiponectin and tumor necrosis factor alpha (TNF-α) with endothelial damages in metabolic syndrome (MS) patients. Methods One-hundred and five patients diagnosed as MS were recruited as cases and 37 subjects without characteristics of MS were recruited as controls. The cases were divided into two groups according to the level of serum von Willebrand factor (vWF) :normal endo-thelial functional MS group (57 patients) and abnormal endothelial functional MS group (48 patients). Serum adi-ponectin concentration was measured by enzyme-linked immanosorbont assay (ELISA). Serum TNF-α concentration was measured by radioimmunoassay (RIA). Results The concentration of serum adiponectin in normal subjects (10.5 mg/L [SD:3.2]) was significantly higher than both that of normal endothelial functional MS group (7.9 mg/L [SD :2.2]) and abnormal endothelial functional MS group (6.5 μg/L [SD :2.5]) (P < 0.05). The concen-tration of serum TNF-α in normal subjects(0.17 μg/L [SD :0.04]) were significantly lower than that of normal en-dothelial functional MS group (0.19 μg/L [SD:0.05]) and abnormal endothelial functional MS group (0.23 ng/mi [SD: 0.06]) (P< 0.05). The level of serum adiponectin were negatively correlated with TNF-α(r=- 0.555, P < 0.01). Logistic regression analysis results showed that high level of TNF-α was a risk factor of endo-thelial damages (OR = 20.649, P = 0.035), whereas high level of serum adiponectin protected against endothelial damages (OR = 0.340,P=0.006). Conclusions Low level of serum adiponectin and high level of serum TNF-α may correlate with endothelial damages in MS patients.

Objective To determine the clinical features and gene expression of neonatal chronic granulomatous disease(CGD) in newborns,in order to provide the evidence for early diagnosis,treatment and infection prophylaxis and so as to improve prognosis.Methods The clinical data of 6 neonates with CGD who hospitalized in Beijing Children's Hospital,Capital University of Medical Sciences,from Jan.to Dec.2013 were retrospectively analyzed,to summarize their clinical features and gene expression.Results All patients were male,mean age of onset in 6 patients was 19 days old.Six patients were onset with cough and fever,3 cases with skin abscesses.All patients had special lung images and their respiratory burst test were all positive.Six patients were all X-linked recessive heredity with mutation in CYBB gene,4 cases carried missense mutation,1 case carried frameshit mutation,1 case had shear point disappear.All patients were improved during hospitalization with anti-infective therapy including antifungal and antibiotic drugs.After their discharge,the patients were followed up for 1 year,among them 5 patients taking antibiotics according to doctor's advise hadn't got any severe infections or other complications,1 patient did not receive antibiotics according to doctor's advise,caught respiratory infection was occured once per 1-2 months and died of multiple organ failure in 5 months due to severe infection.Conclusions For newborn with respiratory symptoms such as cough and fever,with apparently nodular and massive radiologic infiltrates,CGD cases should be highly suspected.Long term prognosis is good in children with prophylactic medication and they may have a longer infection interval.

Objective　To show the condition that the NOSIE (Nurses' Observation Scale for Inpatient Evaluation) used in schizophrenia patients. Method　 To evaluate the male and female schizophrenia patients (paranoid type) by NOSIE. Results　 The total cases were 100 patients, male and female were both 50 cases. The result of evaluation showed that there was significant difference in 5 factors such as social competence, irritability, retardation, psychosis and depressive between male and female patients. As well, it matched with clinical information. The result of the consistency test for survey indicated that its Pearson coefficient of correlation for all of 7 factors in NOSIE were 0.617～0.843. Conclusion NOSICE can provided some objective data to clinical works of nurses. But, in other hand, its identity is lower.

Objective To observe the effects of chronic arsenic exposure on mRNA expression of estrogen receptor-binding fragment-associated gene 9 (Ebag9) and estrogen-responsive finger protein (efp) in uterus and ovary of female rats.Methods Fifty female Wistar rats were randomly divided into five groups according to arsenic (As2O3) concentrations given through drinking-water:0.00 (control),0.05,0.10,0.20,0.40 mg/L arsenic exposure groups and real-time RCR (RT-PCR) was used to detect the mRNA expression of Ebag9 and efp in uterus and ovary tissue at the 31 weeks of experiment.Results The mRNA expression levels of Ebag9 and efp of the 0.00,0.05,0.10,0.20,0.40 mg/L arsenic exposure groups were respectively as follows:0.761 ± 0.178,0.521 ± 0.130,0.544 ± 0.035,0.525 ± 0.198,0.498 ± 0.240 and 0.795 ± 0.171,0.874 ± 0.077,0.797 ± 0.066,0.796 ± 0.040,0.832 ± 0.096.Compared with control group,a decreased tendency was observed in Ebag9 mRNA level(with P value 0.055 in 0.40 mg/L arsenic exposure group) and increased tendency in efp mRNA level in experimental groups (all P ＞ 0.05).The mRNA expression levels of Ebag9 and efp in ovary of the five groups were by turns:0.702 ± 0.484,0.719 ± 0.336,0.693 ± 0.095,0.706 ± 0.055,0.728 ± 0.073 and 0.924 ± 0.061,1.009 ± 0.034,0.930 ± 0.085,0.929 ± 0.068,1.012 ± 0.101.Compared with control group,the expression level of Ebag9 mRNA showed a increased tendency in 0.05,0.20,0.40 mg/L arsenic exposure groups(all P ＞ 0.05).The efp mRNA level increased in experimental groups,with significant difference in 0.05,0.40 mg/L groups (all P ＜ 0.05).Conclusions The expression of efp mRNA has changed in ovary of female rats exposed to chronic arsenic.Arsenic may act as an environmental endocrine disruptor to exert its effect.

One hundred patients with early diabetic nephropathy were randomly divided into control group and study group with 50 cases in each group.All patients received conventional antidiabetic therapy with valsartan tablets 80mg, q.d;patients in study group were given additional TCM Jiawen Dihuang decoction.TCM syndrome scores, relevant biochemical testing and renal function changes were evaluated before and after treatment in two groups.After 8 weeks of treatment, the results showed than the TCM scores in both groups were significantly reduced (study group: 18.9±1.6 vs.7.2±5.1, control group 18.8±1.5 vs.10.3±6.2.both P<0.05);the improvement rate of TCM syndrome in study group was significantly higher than that of control group (90% vs.68%, x2=5.3,P<0.05);and the improvement of relevant biochemical index and renal function in study group was more marked than that in control group.The study indicates that the integrated TCM and Western medicine can enhance the efficacy in treatment of early diabetic hephropathy.
