Objective To investigate the effect of curcumin on renal interstitial fibrosis following unilateral ureteral obstruction (UUO), and compare the effects of Curcumin with that of Enalapril. Method UUO rat model was used. Male Wistar rats were randomly divided into four groups with 8 rats each:shame-operated group (0.9% saline solution), model group (dimethyl sulphoxide, DMSO), Curcumin treatment group [curcumin 100 mg/(kg?d)], and Enalapril treatment group [enalapril 10 mg/(kg?d)]. All rats were killed 4 w after surgery. The degree of tubulointerstitial fibrosis was scored by HE and Masson staining. The sites and levels of protein expression of TGF-?1, CTGF and TIMP-1 were detected by immunohistochemistry staining. Result Compared with those of shame-operated group, the blood urea nitrogen level was significantly increased (P 0.05). Conclusion Pharmacological effects of Curcumin or Enalapril on unilateral ureteral obstruction rats are quite similar. These effects may result from the down-regulation of TGF-?1, CTGF and TIMP-1 expression in kidney tissue.

Objective To compare the effects of curcumin and enalapril on transdifferentiation of renal tubular epithelial cells in unilateral ureteral obstruction (UUO) rats. Method UUO rat model was used. Male wistar rats were randomly divided into four groups with 8 rats each:shame-operated group (0.9% saline solution), model group (dimethyl sulphoxide), curcumin treatment group [curcumin 100 mg/(kg?d)], and enalapril treatment group [enalapril 10 mg/(kg?d)]. Medicines were given intraperitoneally daily two days after the operation. All rats were killed 4w after surgery. The degree of tubulointerstitial fibrosis was scored by HE and Masson staining, and the sites and levels of protein expression of TGF-?1、?-SMA and vimentin were detected by immunohistochemistry staining. Result Compared with shame-operated group, the serum urea nitrogen level was significantly increased (P 0.05). Conclusion The pharmacological effects of curcumin and enalapril may be partly mediated by inhibiting the transdifferentiation of renal tubular epithelial cells towards myofibroblast in UUO rats.

Objective To explore the clinical effect of renal transplant from donation after citizen's death (DCD) donors with acute kidney injury (AKI).Methods This was an observational retrospective study of 622 patients who underwent renal transplantation from 312 DCD donors' kidneys at the First Affiliated Hospital of Xi'an Jiaotong University from December 2011 to December 2016.The transplant patients were divided into AKI group and non-AKI group according to the Acute Kidney Injury Network (AKIN) criteria based on initial and terminal creatinine values.We evaluated and compared transplant outcomes of these two groups.Results There were 131 donors with AKI,and the incidence of AKI was 42.0 ％.AKI group and non-AKI group recipients respectively had DGF in 20.2％ and 7.2％ of cases (P＜0.01),153.6 ± 56.2 and 119.3 ± 40.7 μmol/L of serum creatinine (SCr) levels at 1st month (P＜0.01),and 38.5 ± 14.1 and 57.6 ± 23.4 ml· min-1 (1.73 m2)-1 of eGFR at 1st month (P＜0.01).There was no significant difference in SCr and eGFR between two groups at 1st year after transplantation.Conclusion Most of kidneys from DCD donors with AKI can be considered for transplantation.Renal transplantation of organs from DCD donors with AKI showed greater DGF but good outcomes.

Objective To evaluate the clinical value of adenosine triphosphate (ATP) determination in CD4+ cells in cytomegalovirus pneumonia after renal transplantation.Methods The ATP level of CD4+ T cells was measured by ImmuKnowTM kit.The ATP levels were determined in 187 renal transplant recipients before and 30,60,90,180 days after operation,and at the time of CMV pneumonia and 4 weeks after treatment of CMV pneumonia.The associations between ATP levels and CMV pneumonia were analyzed.Analysis of variance (ANOVA),Pearson-Spearman and relative risks were used for data analysis.Results 17 cases out of 187 renal transplant recipients were diagnosed as CMV pneumonia (9.1％),and the onset of CMV pneumonia started on the (2.8 ±1.2)month after renal transplantation.ATP concentrations in CD4+ T cells were significantly lower after operation than those before operation (P＜0.01).ATP concentrations reached the lowest on the about postoperative day 90 (P＜0.05),then increased gradually.In 17 recipients with CMV pneumonia,the ATP levels before and 30,90 days after operation,at the time of CMV pneumonia and 4th week after treatment of CMV pneumonia were (376 ±182),(283 ± 146),(196 ± 112),(145 ± 102) and (236 ± 117) μg/L respectively.ATP levels at the time of CMV pneumonia were significantly lower than any other time points (P＜0.05).There was close correlation between ATP levels and CMV pneumonia.Conclusion The determination of ATP in CD4+ cells could reflect the status of cell-mediated immunity in renal transplant recipients,and could evaluate the severity and prognosis of CMV pneumonia and guide the clinical treatment.

Objective To investigate impaired fasting glucose(IFG)status of office worker and enterprise personnel in Shiji-azhuang area,for providing a basis for early prevention of diabetes mellitus.Methods The fasting blood glucose level of 109 083 of-fice workers and enterprise personnel in Shijiazhuang area were detected in physical examination in 2012.Results The people of IFG (fasting blood glucose 5.6-<7.0 mmol/L)accounted for 14.61% in all subjects,1 6.61% in men,10.23% in women.3.5 1%male of the 18-<21 years old group were IFG.With the increasing of age,the ratio of IFG people gradually rised to a peak of 30.44% at the age group of 71-<76,and then decreased a little.While the proportion of female with IFG was 1.55% at 18-<21 years old group,with the increasing of age,to the age group of 5 1 - < 56 reached the first peak 20.27%,then decreased at the 56-<61 age group.Rapidly rising again,up to 31.74% the second peak in 76-<81 age group,and then decreased a little.Conclu-sion The proportion of IFG in male is higher than that in female.The proportion of IFG increases with age,and reaches the peak in a certain age (over 70 years old),and then at a relatively stable level.

In recent years, dielectric barrier discharge has been well developed in analytical chemistry, especially in spectrometric analysis. This review emphasizes its applications in atomic spectrometry, including atomic emission spectrometry, atomic absorption spectrometry, and chemical vapor generation for sample introduction to atomic spectrometry.

Objective To explore the clinical curative effect of electromyographic biofeedback on pointed foot in children with spastic cerebral palsy. Methods From June, 2014 to December, 2015, 80 children with spastic cerebral palsy and pointed foot were divided into con-ventional group (n=40) and electromyographic biofeedback group (n=40). The conventional group received exercise and massage, while the electromyographic biofeedback group received electromyographic biofeedback in addition. The passive range of motion (PROM) of ankle, the surface electromyographic results and the selective control results were compared before and eight weeks after treatment. Results After treatment, the PROM significantly decreased in both groups (t>9.142, P<0.001);the integrated electromyography and root mean square, and the selective control increased in both groups (t>3.456, Z>3.178, P<0.01), which were better in the electromyographic biofeedback group than in the conventional group (t>3.737, Z=-2.748, P<0.01). Conclusion Electromyographic biofeedback can further improve the foot dor-sal flexure and pointed foot gait of spastic cerebral palsy children.
