ObjectiveTo describe the status of depressive symptom among children and adolescents with type 1 diabetes mellitus(T1DM) and explore the related factors.MethodsThis was a multi-plot cross-sectional survey.136 cases in Hunan province were investigated by questionnaires.The questionnaires included General Information Questionnaire,Depression Self-Rating of Children( DSRS),Quality of Life Scale for Children and Adolescents.ResultsThe DSRS score of all subjects was (9.51 ± 5.19),24 cases suffered from depressive symptom (17.6％).The multi-factor non-condition logistic regression analysis showed that age(OR =2.831 ),current education status (OR =9.822 ),parents' current marital status (OR =0.061 ),yearly household income (OR =0.415 ),hospitalization in the past 6 months (OR =8.797 ),peer relationship (OR =0.133 ),parent-child relationship(OR =0.182 ),FBS(OR =0.061 ) and sample source(OR =8.366 ) were factors which independently predicted depressive symptom in children and adolescents with T1DM.ConclusionThe influential factors of depressive symptom among children and adolescents with T1DM include age,current education status,parents' current marital status,yearly household income,hospitalization in the past 6 months,peer relationship and parent-child relationship,FBS and sample source.

Objective The study was to investigate the relationship among angiotensin 1-converting enzyme(ACE), plasminogen activator inhibitor-1 (PAI-1)gene polymorphisms and the common carotid artery (CCA-IMT), and the predicting effects of them on CCA-IMT in newly diagnosed type 2 diabetes (T2DM). Methods The polymorphisms of ACE (I/D) gene and PAI-I (4G/5G) gene were deter-mined by polymemse chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele-specific polymerase chain reaction (AS-PCR) method in 308 cases with T2DM. CCA-IMT was compared among the groups with different genotypes of ACE and PAI-1. The in-dependent or synergistic effects of the ACE I/D and PAI-1 40/5G polymorphisms on CCA-IMT in 308 patients with T2DM were analyzed with multivariate linear regression. Then the 156 newly diagnosed type 2 diabetics (durations< I year) without AS received the maltifactorial targeted intervention, including taking aspirin and controlling blood glucose, blood pressure, blood lipid and body weight. The differences of metabolic control, ACE (I/D) and PAId (40/5G) gene polymorphisms were analyzed. Logistic regression analysis was used to analyze the eorrelation among the CCA-IMT, ACE (I/D) and PAI-1 (4G/5G) polymorphisms. Results Patients with ACE DD genotypes had higher CCA-IMT than those with ACE-Ⅱ or ACE ID genotypes. Patients with both ACE DD and PAI-1 404G genotypes had a higher CCA-IMT than those with any other pairs of genotypes. Multivariate linear regression analysis showed that ACE DD and PAI-1 4G4G gene polymorphisms had synergistic effect on the CCA-IMT in T2DM patients. After 2 years multifactorial intervention, the frequencies of PAI-1 4G alleles and 404G genotypas were lower than those in the CCA-IMT non-inereasing group. Conclusions These findings indicate that the ACE-DD geno-type and its synergistic effects with the PAI-1 4G/4G genotype are independent risk factors for the CCA-IMT in T2DM patients. Under multi-factorial intervention for 2 years, PAI-1 4G/4G genotype may be a negative predictor for the progression of CCA-IMT in T2DM patients.

Objective To investigate epidemiologically the prevalence of obesity and overweight in Mongolian and Han residents aged over 55 years old in pastoral area of Inner Mongolia,China.Method From 2008 to 2009,with diagnostic criteria of overweight and obesity adopted by Chinese and World Health Organization (WHO),an epidemiological investigation was carried out in 9 146 subjects.Result The incidences of obesity and overweight in Mongolian and Han residents were 32.43％ (32.25％ by WHO criteria),19.09％ (9.91％),and 33.60％ (29.85％),15.19％ (7.66％),respectively.The prevalence of obesity in Mongolian residents was higher than that in Han residents (x2 =16.272,P＜0.01).The status of obesity in Mongolian and Han female residents was more marked than that in male residents (P ＜ 0.05).Overweight between male and female of Han population was different(x2 =5.541,P =0.019).The prevalence of obesity between Mongolian and Han was statistically different (x2 =16.272,P＜0.01).Waist circumference,waist/height ratio,and body mass index between Mongolian and Han were also different (all P ＜ 0.01).Conclusion Differences in prevalence of overweight and obesity were found between Mongolian and Han ethnics among residents aged over 55 in pastoral area of Inner Mongolia,China.

Objective To investigate the role of polymorphisms of scavenger receptor class B gene CD36 in affecting the progress of subclinical atherosclerosis (AS) and the associated factors affecting the expression of CD36 on the surface of peripheral blood monouclear cells (PBMC) and the association between CD36 expression and progress of subclinical AS in type 2 diabetic patients.Methods CD36 polymorphisms (CD36-rs1984112, CD36-T620C) were typed by PCR-RFLP in 470 cases of type 2 diabetes mellitus and 220 non-diabetic controls of Hans in Hunan area.The genotypes and allele frequencies were compared between cases and controls.Fluorescence intensity of CD36 on the surface of PBMC was analyzed in 102 cases of type 2 diabetes mellitus by flow cytometry and was compared between the patients without AS and the patients with subclinical AS.Multiple linear regression was applied to evaluate the relevant factors contributing to CD36 expression.Results The genotypes and allele frequencies of CD36-rs1984112 in type 2 diabetes mellitus were not significantly different between cases and controls (P＞0.05), either did CD36-T620C (P＞0.05).The mean florescence intensity (MFI) of CD36 in type 2 diabetics with subclinical AS was higher than that without AS (1 382±659 vs 1 173±340, P＜0.05).Factors affecting the CD36 expression were: age (P=0.005), gender (P=0.021), systolic blood pressure (SBP) (P=0.027), standardized coefficients Beta was 0.28, 0.31 and -0.21, respectively.Age contributed to the CD36 expression level in males (P=0.002) and diastolic blood pressure in females (P=0.001) respectively.Conclusion CD36-rs1984112 and T620C seem not to be a functional polymorphism sites in Hans of Hunan, southern China.CD36 expression level is higher in type 2 diabetics with subclinical AS in contrast with those without AS.CD36 expression on PBMC surface is higher in aged males with lower SBP.

Objective To explore the clinical value of the level of granzyme B and perforin mRNA in urine for the diagnosis of renal transplantation patients with delayed graft function (DGF). Methods Twenty-four cases of renal transplantation patients with DGF were included in this study. Seventy-three u-rine specimens were obtained from these patients who received graft biopsies. Among the 24 cases, ureteral obstruction occurred in 2 cases, vascular thrombosis in 1 case, acute CsA intoxication in 3 cases, acute tubu-lar necrosis (ATN) in 7 cases, ATN complicating borderline change in 2 cases, ATN complicating acute re-jection (AR) in 3 cases, AR in 6 cases. Total RNA was isolated from the urinary cells. Messenger RNA (mRNA) encoding the cytotoxic proteins perforin and granzyme B gene were measured with the quantitative polymerase-chain-reaction assay-(RT-PCR). SPSS13.0 software was used for data analysis. Levels of mRNA were log-transformed before analysis. Results The levels of perforin and granzyme B mRNA in u-rine among the ureteral obstruction group, vascular thrombosis group, acute CsA intoxication group and ATN group were very low. There was no significant difference among these groups (P>0.05). However,among the ATN complicating borderline change group 1.22, 0. 97 fg/μg, ATN complicating AR group (1.20±0.39), (1.07±0.30)fg/μg, and AR group(11.13±0. 33), (1.01±0.19)fg/μg, the levels were increased significantly(P<0.001). Conclusion Measurement of mRNA encoding the cytotoxic proteins perforin and granzyme B gene in urinary cells in renal transplantation patients with DGF could be helpful to etiological diagnosis of DGF, and might be used as an index for the appropriate management of the borderline change.

Objective To assess the safety and effectiveness of laparoscopic implantation of three-dimensional (3D)-printed extravascular stent for treatment of nutcracker syndrome (NCS).Methods The clinical data of NCS in our hospital were prospectively collected from August 2015 to August 2016.Doppler ultrasound and CT examination were performed before the operation of all the patients who were in line with the diagnostic criteria of NCS.The 3D model of extravascular stents with especial device to prevent migration was designed and was made by 3D metal printer with titanium alloy.The left renal vein(LRV) was exposed completely up to the inferior vena cava,then the stent was placed around the compressed LRV.Results 10 patients were enrolled in the study,including 9 males and 1 females,age (21.5 ±4.6) years.Among these patients,there were 4 cases with severe hematuria,1 case with proteinuria,5 cases with left lumbago,and 5 cases with left severe varicocele.The preoperative doppler ultrasound examination showed the diameter of the the compressed LRV was (1.57 ± 0.25) mm,and flow velocity was (164.40 ± 55.27) cm/s;the diameter of the LRV at the renal hilum was (8.7 ± 1.59) mm,and flow velocity was (10.70 ± 2.21) cm/s.The average operation time was (75 ± 11) min,and the average hospital stay after operation was 7 d.All symptoms were relieved at 3-7 d after operation.All patients were asymptomatic and all stents were stable after follow-up.At 12 months after surgery,the diameter of the LRV at the renal hilum was (8.23 ± 1.90) mm on doppler ultrasound,and there was significant decrease (P ＜ 0.01);the flow velocity was (21.20 ±3.88) cm/s,and there was significant increase (P ＜ 0.01).Conclusions Laparoscopic three-dimensional printed extravascular stent placement is a safe,effective and minimally invasive technique for treatment of NCS.

OBJECTIVETo examine the distribution of 3 polymorphisms of lecithin cholesterol acyltransferase gene in Chinese population and the association of these polymorphisms with lipid metabolism in patients with atherosclerotic heart disease (CHD).

METHODSGenotypes and frequencies of 3 sites were examined by PCR-restriction fragment length polymorphism technique in 209 unrelated normal control individuals and 203 CHD patients.

RESULTSThe observed allele frequencies conform well to Hardy-Weinberg equilibrium. The frequency of 608T allele was significantly higher in controls than that in patients (P=0.034). Compared with the CHD patients without 608T, the CHD patients with 608T exhibited a significant increase in plasma HDL-C concentration (P=0.015). 911T/C and 1188C/T polymorphisms were not found in either group.

CONCLUSION608T polymorphism of LCAT gene was associated with higher plasma HDL-C level in CHD patients, while 911T/C and 1188C/T polymorphisms maybe very rare in Chinese population.

BACKGROUNDTo investigate the surveillance trend of birth defects, incidence, distribution, occurrence regularity, and their relevant factors in Xi'an City in the last 10 years for proposing control measures.

METHODSThe birth defects monitoring data of infants during perinatal period (28 weeks of gestation to 7 days after birth) were collected from obstetrics departments of all hospitals during 2003-2012. Microsoft Excel 2003 was used for data input, and Statistical Package for the Social Sciences version 16.0 (International Business Machines Corporation, New York, NY, USA) was used for descriptive analysis. χ2 test, Spearman correlation and linear-by-linear association trend test were used for statistical analyses.

RESULTSThe birth defect rate declined from 9.18% in 2003 to 7.00% in 2012 (χ2 = 45.001, P < 0.01) with a mean value of 7.85%, which is below the Chinese national average level (χ2 = 20.451, P < 0.01). The order of five most common birth defects has changed. The incidence of congenital heart disease (CHD) increased with time, particularly after 2012, it became the most frequent type (r s = 0.808, P < 0.001). Till then, the number of neural tube defects (NTDs) declined significantly (χ2 = 76.254, P < 0.01). The average birth defects rate of 8.11% in rural areas was higher than that in urban areas (7.56%, χ2 = 7.919, P < 0.01) and much higher in males (8.28%) than that in females (7.18%, χ2 = 32.397, P < 0.01). Maternal age older than 35 years (χ2 = 35.298, P < 0.01) is the most dangerous age bracket of birth defects than maternal age younger than 20 years (χ2 = 7.128, P < 0.01).

CONCLUSIONSA downward trend of birth defects was observed in Xi'an City from 2003 to 2012. NTDs significantly decreased after large-scale supplemental folic acid intervention, while the incidence rate of CHD significantly increased.
