Objective To detect serum Vaspin level in subjects with normal glucose regulation(NGR)and newly-diagnosed type 2 diabetes mellitus (T2DM) ,and to investigate the association between serum Vaspin and body mass index (BMI), age, gender, glycometabolism and lipemetabolism and insulin sensitivity index. Methods The fasting serum levels of Vaspin were measured in 48 normal controls and 66 T2DM patients using enzyme linked immunosorbent assay ( ELISA ). BMI, waist-hip ratio (WHR) and % body fat were measured,as well as fasting blood glucose (FBG), HBA1C, lipids and insulin levels. Results The fast serum Vaspin concentrations in the obese T2DM patients was ( 1.13 ±0. 25 ) μg/L,which were significantly higher than that in the non-obese T2DM patients (0. 65 ± 0. 13 ) μg/L (P < 0. 01 ). In the NGR group, the fast serum Vaspin concentrations in the obese was (0. 95 ± 0. 11 ) μg/L, which were significantly higher than that in the non-obese (0. 38 ± 0. 18) μg/L( P < 0. 01 ). In the T2DM group, serum Vaspin concentration in females ( [0. 92 ± 0. 35]μg/L) was higher than in males ([0.76 ± 0. 22] μg/L) (P < 0.01 ). In the NGR group, serum Vaspin concentration in females was also higher than that in males ( [1.05 ± 0. 21] μg/L vs [0. 48 ± 0. 14] μg/L) )(P<0. 01 ). Serum Vaspin level was positively correlated with BMI,WHR,% Body Fat,fasting insulin(FINS)and insulin sensitivity index (ISI) (r = 0. 365,0. 214,0. 238,0. 183 and 0. 147, respectively, Ps < 0. 05 ). The multiple stepwise regression analysis showed that gender( R2 = 0. 161, P < 0. 01 ), ISI ( R2 = 0. 183, P < 0. 01 )and WHR( R2 = 0. 216, P < 0. 01 ) were independent variables associated with Vaspin. Conclusion Serum vaspin level significantly increases in subjects with obesity, and independently associated with gender, ISI,WHR. These findings suggest that serum Vaspin may be involved in the pathophysiology of insulin resistance syndrome.

Objective To screen for selective transforming growth factor β(TGF-β)inhibitors from the compound library, and analyze their structure-activity relationship. Methods The inhibiting activities of 170 compounds to TGF-βpathway were evaluat-ed by the SMAD3 luciferase reporter system;the positive hits were examined for their selectivity towards activin receptor like kinase (ALK)4、ALK5 or ALK7 by a molecule based screening system composed of SMAD3,ATP and the purified kinase domain for ALK4, ALK5 or ALK7;the EGFP-SMAD2 fusion protein redistribution assay was used to confirm the inhibiting effects of positive hits. The structure-activity relationship was analyzed by comparing the docking module of SB431542 with ALK5 kinase domain. Results Fif-teen compounds were found capable of inhibiting luciferase expression downstream of SMAD3 with≥25%inhibitory rate;several of them showed different selectivity towards ALK4,ALK5 and ALK7. Compound 63 selectively inhibited the activity of ALK4 and ALK7 with IC500.234 and 0.370μmol/L,respectively,while compound 64 showed inhibiting activity towards all three kinases with the IC50 values 10,6 and 85 nmol/L for ALK4、ALK5 and ALK7,respectively. In addition,compounds 63 and 64 further inhibited the TGF-β1 induced EGFP-SMAD2 nuclear translocation,with the IC50 values of 0.45 and 6.30μmol/L,respectively. The MTT anti-proliferative assay indicated that compounds 63 and 64 exerted these activities at non-toxic concentrations. The analysis of structure-activity rela-tionship indicated that the compounds sharing a core structure,the 1,2,4-triarylimizazole or 1,3,5-triarylpyrazoline,with the 3,4 methyoenedioxyphenyl,6-methylpyridine and 4-aminocarboxyl substitution groups tended to exhibit better activities. Conclusion The two potent TGF-βpathway inhibitors,63 and 64 are identified through this screening project,of which,63 selectively inhibited the ALK4 and ALK7 activity,while 64 showed inhibiting activity towards all three tested types of ALKs.

Objective:To explore the correlation between glycated hemoglobin variability index (HGI) and carotid artery plaque in patients with type 2 diabetic kidney disease (DKD).Methods:This cross-sectional study included 620 DKD patients admitted to the Department of Endocrinology in the First Affiliated Hospital of Nanjing Medical University from June 2019 to June 2022. Basic demographic and laboratory data, including age, disease duration, body mass index (BMI), blood pressure, fasting blood glucose (FBG), glycated hemoglobin (HbA 1c), lipid profile, and urinary albumin excretion rate (UAER), were collected for all participants. A linear regression equation was developed based on FPG and HbA 1c to calculate the HGI level of each patient. The patients were divided into low HGI group, medium HGI group, and high HGI group based on the tertiles of HGI. The detection rate of carotid artery plaque in the three HGI groups was analyzed. The patients were further divided into the non-plaque group (254 cases) and plaque group (366 cases) based on the presence or absence of carotid artery plaque. Binary logistic regression analysis was used to identify the risk factors for carotid artery plaque in DKD patients. Results:Among the DKD patients, the detection rate of carotid artery plaque was 59%. Compared with the non-plaque group, the patients in the plaque group had older age (60.52 years, t=-7.71), longer disease duration (10 years, Z=-4.17), higher systolic blood pressure (141.9 mmHg, t=-3.29), higher HbA 1c (9.2%, Z=-2.17), higher HGI (-0.20%, Z=-3.43), higher urea nitrogen (6.87 μmol/L, Z=-3.96), higher creatinine (77 mmol/L, Z=-4.05), and higher UAER (234.25 mg/24 h, Z=-5.59) (all P<0.05). The detection rate of carotid artery plaque in the low HGI group, medium HGI group and high HGI group was 50.5%, 57.9% and 68.5%, respectively, with a statistically significant difference among the three groups (χ 2=14.15, P=0.001). Age, UAER, and HGI were identified as risk factors for carotid artery plaque ( OR=1.051, 2.775 and 1.474, all P<0.05). The risk of carotid artery plaque in the high HGI group was 2.142 times of that in the low HGI group. After adjusting for confounding factors such as age, gender, disease duration, BMI, blood pressure, lipid profile and UAER, the risk of carotid artery plaque in the high HGI group was 2.558 times of that in the low HGI group. Conclusion:HGI is significantly elevated in DKD patients with carotid artery plaque, and the detection rate of carotid artery plaque increases with HGI level. Elevated HGI is an independent risk factor for carotid artery plaque in DKD patients.

Objective To investigate the epidemiological characteristics of cerebral palsy(CP)in children aged 1-6 years in China,including the incidence,prevalence,type of CP,etiology,prevention and rehabilitation status. Methods The survey was carried out by standard questionnaires,multi-center collaboration,stratified-cluster ran-dom sampling method.The surveyed adopted the following principles:streets in the city and villages in the rural areas, and the number of the urban and rural children was the same,and the proportion of children in each age group was balanced.The investigation areas included provinces and autonomous regions,including Heilongjiang,Beijing,Henan, Shandong,Shanxi,Shaanxi,Anhui,Hunan,Guangxi,Guangdong,Chongqing and Qinghai,and 323 858 children were in-vestigated.Results The incidence of CP was 2.48‰(155/62 591 cases),and the prevalence was 2.46‰(797/323 858 cases)(1-6 years old).The prevalence varied in different regions,in which the highest prevalence was 5. 40‰(54/9 998 cases)in Qinghai province,and the lowest prevalence was 1.04‰(47/45 133 cases)in Shandong province.The prevalence of the males(2.64‰,461/174 391 cases)was higher than that of the females(2.25‰, 336/149 467 cases),and the difference was statistically significant(P<0.05).The types of CP were spastic type (58.85%,469/797 cases),mixed type(13.17%,105/797 cases),dyskinetic(9.79%,78/797 cases),hypotonic (8.28%,66/797 cases),ataxia(6.25%,52/797 cases)and rigid(3.39%,27/797 cases)respectively in 797 CP children.The first three risk factors for CP were long -term exposure to harmful physical factors during pregnancy, whether there were birth defects among the three generations of relatives of the children,such as children's peers, parents or grandparents,whether there were birth defects among the children's peers,parents or grandparents,and neonatal jaundice or persistent jaundice.Among 797 CP children,79.67% of the children with CP were timely detected and treated in the local hospitals,while the other 19.93% of them were not timely treated.The places which could give them timely detection and early diagnosis and treatment were general hospitals(42.97%),Maternity and Infant Hospitals (27.03%)and Children's Hospitals(20.31%). The main rehabilitation methods for 797 children with CP were 34.58% in the hospitals or rehabilitation centers,31.61% in the communities(including at home),33.80% mainly in the medical institution,and in the communities they could also receive partially rehabilitation services. Conclusions The prevalence of CP in China is coincident with international levels.The prevalence rate of CP in males is higher than that in females.The types of CP distribution are accorded with international distribution characteristics.There were still some children with CP who could not receive timely detection and treatment.Rehabilitation at the medical institutions is the chief way and proper rehabilitation guidance should be carried out in the communities.
