Objective To investigate the prevalence of renal insufficiency and its associated factors in type 2 diabetes mellitus with normoalbuminuria using estimated glomerular filtration rate ( eGFR) .Methods We retrospectively analyzed 10-year data of chronic complications in type 2 diabetics in-patient from the Chinese Diabetes Society.eGFR was estimated using the equation from Modification of Diet in Renal Disease(MDRD) study.The clinical characteristics as well as associated factors for low eGFR were analyzed among the normoalbuminuric type 2 diabetic patients.Results A total of 1351 type 2 diabetic patients were included, 755 patients with normoalbuminuria, 466 patients with microalbuminuria and 130 patients with macroalbuminuria respectively.Among the patients, 310 (22.9% ) had low eGFR (GFR <60 ml · min~(-1) · 1.73 m~(-2) ) , 19.7% (149/755) in the patients with normoalbuminuria, 21.9% (102/466) in microalbuminuria and 45.4% ( 59/130 ) in macroalbuminuria Patients with normoalbuminuria and low eGFR suffered more chronic complications than those with normoalbuminuria and normal eGFR, mainly retinopathy, cerebrovascular diseases and sensory neuropathy.Stepwise logistic regression analysis revealed that age ( OR = 1.042, P < 0.001), diabetic duration ( OR = 1.038, P = 0.045), systolic blood pressure (OR = 1.017, P < 0.001) were independently associated with renal impairment among the patients with normoalbuminuria.Body mass index ( OR = 0.868, P < 0.001) and HbAlc (OR =0.898, P =0.021) were also related with renal insufficiency.Conclusion A considerable proportion in type 2 diabetic patients without albuminuria may exist renal impairment, and eGFR estimation could benefit the evaluation of renal function in such patients.

Objective To analyze the effects and experience of ideological and political education through inquiring students' satisfaction on it,and to strengthen innovation and efficiency. Methods Five hundred and fifty university students were chosen by random.Through anonymous questionnaires,information on attention and satisfaction of ideological and political education about educate by all staff,campus culture,psychological status,and extracurricular activities were acquired.Results More than 56% of the students thought who impressed them most were the professional teachers;and 75.64% of them would ask friends for help when they were facing difficulties.And 44.91% considered study as the main resource of pressure,although the other 39.09% chose the career perspective.Then,57.45% were willing to take part in the meaningful activities after class,though the study was tough.And 45.45% hoped it would be a great progress on extracurricular activities;74% would take part in entertainment,and on the other hand 68.55% chose volunteer;and 87.72% interested in learning psychological knowledge. Conclusion It is important to strengthen and develop ideological and political education among students in the university.And attention should be paid to the innovation and efficiency of the education.

BACKGROUND:Our previous studies have shown that strontium-doped calcium polyphosphate containing low-dose strontium appears to have a significant effect on angiogenesis-related behaviors of monocultured umbilical vein endothelial cells and osteoblasts.
OBJECTIVE:To investigate the effect of strontium-doped calcium polyphosphate on angiogenesis-related behaviors of umbilical vein endothelial cells and osteoblasts co-cultured, including celladhesion, spreading, proliferation, as wel as the protein secretion of vascular endothelial growth factor and basic fibroblast growth factor from co-culture system in vitro.
METHODS:Human umbilical vein endothelial cells and osteoblastic cells (MG63) were utilized in this study. cells from passage 3 were used for preparation of the cel-scaffold constructs. After placed in 24-wel plate at a ratio of 2:1, human umbilical vein endothelial cells and MG63 cells were seeded onto strontium-doped calcium
polyphosphate, calcium polyphosphate and hydroxyapatite scaffolds and co-cultured for 7 days. The vascular endothelial growth factor and basic fibroblast growth factor protein levels were determined through a double ligand enzyme-linked immunosorbent assay. The colorimetric 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay was performed to quantify the effect of scaffolds on cellproliferation.
RESULTS AND CONCLUSION:Compared with those on calcium polyphosphate and hydroxyapatite scaffolds, cells on strontium-doped calcium polyphosphate scaffolds attached and spread better with a significantly improved cellproliferation. More importantly, the vascular endothelial growth factor and basic fibroblast growth factor expressions were significantly higher in the strontium-doped calcium polyphosphate group than the other two groups (P<0.05), indicating strontium-doped calcium polyphosphate can up-regulate levels of vascular endothelial growth factor and basic fibroblast growth factor proteins.

Objective To discuss the clinical value of electronic bronchoscopic intervention in treatment of tracheobronchial tuberculosis. Methods Clinical features of 45 patients with tracheal and bronchial tuberculosis which were confirmed by electronic bronchoscope and treated by bronchoscopic intervention were retrospectively analyzed from January 2007 to December 2013 in our hospital. Results The efficiency of bronchoscopic intervention is 88.9%, of which 28 cases achieved a significant effect (accounting for 62.2%). Conclusion Electronic bronchoscopic intervention is a preferred way in treatment of tracheobronchial tuberculosis.

Objectives To study the psychological characteristics of children with attention deifcit hyperactivity disorder (ADHD). Methods Human ifgure drawings (HFD) as a projective technique was performed in 107 children with ADHD aged (8.69 ±1.48) years old (6.5~11.5 years), and 107 matched healthy children. Characteristic features of the HFDs in children with ADHD, and correlations between emotional indicators of the HFDs and factors of child behavior checklist (CBCL) were assessed and com-pared with the control group. Results Signiifcant differences in emotional index were found between ADHD and healthy chil-dren, including bad body composition, short arms, long arms, big ifgure, omission of hands and omission of feet (P<0.05). Nega-tive correlation was found between the HFDs emotional index and the factors of activity and social ability in the CBCL (P<0.05), but a positive correlation was found between the HFDs emotional index and behavioral problem (P<0.05). Conclusion Human ifgure drawings can relfect some emotional characteristics of children with ADHD, and when combined with CBCL, it can pro-vide evidence for diagnosis and intervention for ADHD.

Objective To observe the influence of recombinant human brain natriuretic peptide(rhBNP)treatment on serum C-reactive protein(CRP)level in patients with congestive heart failure.Methods Forty patients with congestive heart failure(NYHA class Ⅳ)were divided into experimental group(n=20)receiving rhBNP and control group(n=20)receiving isosorbide dinitrate.Blood pressure and central venous pressure were observed and hypersensitive CRP was checked before and one week after treatment in both groups.Results No obvious change of blood pressure at each time point was found after BNP treatment(systolic blood pressure:P=0.804;diastolic blood pressure:P=0.492)while significant decrease of CVP was noted(P=0.016).Serum CRP level was significantly decreased one week after BNP treatment(10.1?7.4 mg/L vs 7.7?5.0 mg/L;P=0.013)in experimental group,obviously different from that in the control group(P=0.044).hsCRP change was positively related to CVP change(Pearson correlation:0.469,P=0.043).Conclusion Brain natriuretic peptide effectively decreases serum C-reactive protein level in the patients with congestive heart failure,indicating its possible role in relieving inflammation in heart failure.
