Objective To investigate the clinical significance of urine transferrin in the type 2 diabetic nephropathy and primary chronic glomerular disease. Methods The level of TRF and UAER in the urine of 114 patients with type 2 diabetes mellitus (T2DM), 108 patients with CGD and 30 healthy patients was measured by rate nephelometry and analyzed. Results Urine TRF significantly increased earlier than ALB at the early stage of DN; Linear correlation was found by correlation analysis between the level of TRF in urine level and the quantity of protein in urine. Conclusion TRF in urine obviously increased at the early stage of DN. It was more sensitive than UAER to reflect the early renal injury of DM. A statistically significant correlation was found between the TRF level and the quantity of protein in the urine.

Objective To study the inhibitory effect and its mechanism of sodium butyrate on human laryngeal carcinoma in nude mice. Methods Human laryngeal carcinoma cell line Hep-2 was seeded in the subcutaneous layer of 12 nude mice to built laryngeal carcinoma xenograft model. Then they were randomly and equally divided into 2 groups. Sodium butyrate was given in experimental group while phosphatic-buffered saline (PBS) was used in control group for 4 weeks. Tumor size and body weight of the mice were measured at regular time-intervals. The tumor,heart,liver,lungs,spleen and kidneys were removed at the end of treatment. Tumor sections were examined by electronic microscopy. TUNEL method and immunohistochemical S-P method were used for detecting the expression of Ki-67 nuclear antigen and survivin protein. The heart,liver,lung,spleen and kidney sections were examined after HE staining for assessment of toxicity. Results In experimental group,the volume of tumors was reduced,the area of necrosis in tumors was widened,the apoptotic rate was increased obviously and the expression level of Ki-67 nuclear antigen and survivin protein was decreased as compared with control group. During treatment,all the nude mice grew well and there were no toxic reactions. At the end of treatment,there were no abnormal changes in heart,liver,lung,spleen and kidney sections examined under light microscope. Conclusion Sodium butyrate can significantly inhibit the growth of human laryngeal carcinoma xenograft in nude mice. Its mechanism may be related to the apoptosis in tumor cells by inhibiting the expression of survivin protein and Ki-67 nuclear antigen. There is no toxicity to heart,liver,lungs,spleen and kidneys at a treatment dose of sodium butyrate.

Objective To explore the DNA damage in peripheral blood lymphocytes of rats exposed to sodium arsenite. Methods Thirty-two Wistar rats, weighing 180 - 200 g, equal male and female, were randomly divided into 4 groups, 8 in each group. Sodium arsenite 0(control) ,0.05,0.15,0.45 mg/L were given through drinking water for 30 days. Body weight and drinking water consumption were measured every day. Blood were collected and DNA damage in peripheral blood lymphocytes was examined by single cell gel electrophoresis.Results The increase of body mass[( 121.00 ± 38.57), ( 120.62 ± 42.80), ( 125.38 ± 48.68)g]and water intake [(36.9 ± 6.2), (37.9 ± 5.8), (39.3 ± 4.2)ml/d]in 0.05,0.15,0.45 mg/L sodium arsenite groups were compared with the control group[( 119.25 ± 47.27)g, (38.4 ± 5.1 )ml/d], and the difference were not significant (F = 0.040,0.828, all P ＞ 0.05). The tail ratios[46.25%(185/400) ,57.00%(228/400),64.00%(256/400)], tail lengths [(32.89 ± 17.18), (58.74 ± 36.28), (77.55 ± 35.73 ) μm]and tail moments [(6.29 ± 3.74), ( 11.20 ± 9.64),(17.30 ± 12.60)μm]in 0.05,0.15,0.45 mg/L sodium arsenite groups were significantly higher than those of the control group[39.25%(157/400), (18.73 ± 15.83),(2.61 ± 1.05)μm, all P ＜ 0.01], and the tail ratios,tail lengths and tail moments in lymphocytes increased with increased doses of arsenic concentration. Conclusions Low doses of arsenic exposure can induce DNA damage in peripheral blood lymphocytes of rats.

Objective To investigate the expression and significance of death receptor 4(DR4) and DR5 in human craniopharyngioma.Methods The expression of DR4 and DR5 was determined by immunohistochemistry and in situ hybridization in 28 samples of craniopharyngioma and 25 samples of normal brain tissue.Results With low expression in partial normal brain tissue,DR was expressed highly in all of the craniopharyngioma samples.High DR expression in craniopharyngioma tissue differed from low DR expression in normal brain tissue(P0.05).Conclusions High DR expression is prevalent in craniopharyngioma tissue.This may contribute to the apoptosis-induced therapy of craniopharyngioma.The control of DR expression lays in protein level.This may contribute to the selective induced-apoptosis of tumor necrosis factor-related apoptosis-induced ligand.

BACKGROUNDCoronary artery lesions (CALs) are known to be the main complication in children with Kawasaki disease (KD). Instead of intravenous immunoglobulin (IVIG), corticosteroid therapy has been accepted to be used for children with KD who are unresponsive to IVIG. This study aimed to evaluate risk factors for CALs in children with KD.

METHODSWe retrospectively reviewed the clinical records of 2331 children with KD from January 2005 to December 2014. To identify the independent risk factors for CALs, multivariable logistic regression models were constructed using significant variables identified from univariate logistic regression analysis.

RESULTSThe incidence of CALs was 36.0% (840 of 2331), including 625 (26.8%) coronary artery dilations and 215 (9.2%) coronary artery aneurysms (CAAs). Multivariable logistic regression analysis identified that male, incomplete KD, longer fever duration, and C-reactive protein (CRP) >100 mg/L were independent risk factors for coronary artery dilatations. On the other hand, male, incomplete KD, longer fever duration, prolonged days of illness at the initial treatment, corticosteroid therapy, sodium ≤133 mmol/L, and albumin <35 g/L were the independent risk factors for CAAs. In addition, corticosteroid therapy, prolonged days of illness at the initial treatment, and albumin <35 g/L were the independent risk factors for giant CAAs.

CONCLUSIONSCALs might be associated with male sex, incomplete KD, longer fever duration, prolonged days of illness at the initial treatment, albumin <35 g/L, sodium ≤133 mmol/L, CRP >100 mg/L, and corticosteroid therapy. Corticosteroid therapy was an independent risk factor for CAAs and giant CAAs. Thus, corticosteroids should be used with caution in the treatment of KD with the risk for CALs.

Objective To explore the behavior and initial sandtray characters of the children with oppositional defiant disorders (ODD) in order to provide psychological and behavioral intervention as early as possible.Methods The differences of the Conners parent symptom questionnaire (PSQ) and initial sandtrays between 24 children with ODD and 24 normal children were compared.Results PSQ indicated that children with ODD had higher scores of conduct proble((1.31 ± 0.53),(0.36 ± 0.31)),learning problem ((2.01 ± 0.66),(0.57 ±0.5)),hyperactivity-impulsion ((1.60 ± 0.77),(0.35 ± 0.41)),anxiety ((0.60 ± 0.50),(0.27 ± 0.25)) and hyperactivity index((1.12 ± 0.31),(0.78 ± 0.28)) than normal children.On the use of toys,the experimental group was significantly higher in armament and transports and lower in plants and stones(P＜0.05).On the theme of sandtrays,the ODD group was significantly higher in disorder,neglect,injury,threat and lower in integration and energy (P ＜ 0.05).Conclusion The results show that the children with ODD have more anxiety experience than normal children and this may be associated with oppositional conduct.Children with ODD use more aggressive toys and wounded themes,revealing their attack and conflict.Psychological intervention can be provided according to the characters of behavior scale and initial sandtray.

Objective To investigate the cognitive impairment and time-on-task characteristics of combined type(C type) and predominantly inattentive type (Ⅰ type) of children with attention deficit hyperactivity disorder(ADHD).Methods 24 cases with C type ADHD,20 cases with Ⅰ type ADHD and 24 normal children were completed 2 Block period of continuous performance test task,with conducting a comparative analysis of the behavior results of three groups and block1 and block2.Results 1.three groups comparison:hit numbers of C type (64.37 ±5.29) and Ⅰ type (63.55 ±5.28) were lower than that of the normal control group(67.04 ±2.03) ; reaction time of Ⅰ type (540.33 ± 90.33) ms was longer than that of the normal control group (470.56 ± 95.39)ms; intra-individual variability(ⅡⅤ) of C type (174.24 ± 56.3)ms and Ⅰ type (201.12 ± 50.79)ms were higher than that of the normal control group(144.72 ± 37.17) ms.Commission errors of other figures after 1 of C type was higher than that of Ⅰ type; reaction time of commission errors of Ⅰ type[(701.34 ±311.54) ms] was longer than that of C type((512.57 ± 279.22)ms),and all the differences were statistically significant (P ＜ 0.05).2.Timeon-task comparison:hit numbers,omission errors and ⅡⅤ had the significantly main effect of the type of subjects (P ＜ 0.05) ; hit numbers,omission errors,reaction time and ⅡⅤ had the significantly main effect of time-on-task (P＜0.01) ; Block2 the reaction time of C type and Ⅰ type((501.82 ± 112.47)ms,559.33 ± 90.73)ms) were significantly longer than that of Block1 ((473.19 ± 106.43) ms,(523.45 ± 99.86) ms) (P ＜ 0.05),while no significant difference (P＞0.05) in the normal control group.Conclusions C type ADHD has attention deficit and impulsivity and response inhibition defects.Ⅰ type ADHD has attention deficit and information processing capacity backward.Reaction rate of ADHD is more vulnerable to the impact of time-on-task.Two subtypes of ADHD children has different modes of cognitive impairment.

Calcium hydroxide (CH) is applied to improve disinfection of root canals in most root canal retreatment. This study aimed to analyze the CH removal efficacy using 7 different root preparing files (K file, pre-curved K file, EndoActivator, Ultrasonic file, pre-curved ultrasonic file, F file and needle irrigation alone) with apical transportation. Standardized models of curved canal with such apical transportation or not were set up before applying CH to root canal for 7 days. Seven techniques described above were used for its removal. Then the roots were disassembled and digital photos were taken. The ratio of residual CH in the overall canal surface was calculated using the image analyzer image pro plus 6.0. The data were analyzed using one-way ANOVA with post hoc Tukey test. Results revealed that CH was effectively removed (P<0.05) by using all 6 mechanical methods except irrigation alone. In curved root canals with apical transportation, EndoActivator, pre-curved ultrasonic file and F file were found to be more effective in removing CH than the other four file (P<0.001), while there was no significant difference among EndoActivator, pre-curved ultrasonic file and F file groups (P>0.05). The percentage of residual CH in the canal with apical transportation was higher than that in the canal without apical transportation (P<0.05). In conclusion, CH can be hardly removed completely. Canal with apical transportation will result in insufficient CH removal. EndoActivator, pre-curved ultrasonic file and F file are more effective in the curved root canal with apical transportation.
