Objective To compare the serum thyroid hormones level in patients with pre-diabetes,newly diagnosed type 2 diabetes mellitus(T2DM)and healthy people,and to investigate the association of glucose metabolism with thyroid function.Methods Sixty newly diagnosed T2DM patients(T2DM group),60 pre-diabetes patients(pre-diabetes group),and 60 healthy people(healthy group) from outpatient departments were randomly enrolled in the study.Their thyroid peroxidase antibodies(TPOAb),thyroglobulin antibodies(TGAb),thyrotropin receptor antibodies(TRAb),and thyroid color dopplar ultrasound were all normal.Thyroid hormones was measured.Glycosylated hemoglobin A1c(HbA1c),fasting plasma glucose(FPG),glycated albumin(GA) was additionally measured in T2DM patients.We compared the difference of thyroid hormones among the 3 groups and investigated the factors that influence thyroid hormones level in each T2DM patients.Results There was no significant difference found on thyroid hormones level between the pre-diabetes group and healthy group(P＜0.05).T3 and FT3 level were(1.34±0.24)nmol/L and(3.88±0.51)pmol/L in the T2DM group,respectively,which were significantly lower than those in the pre-diabetes group([1.48±0.29]nmol/L and [4.12±0.55]pmol/L,t=-0.135 and -0.145,respectively,Ps＜0.01＝ and in the healthy group([1.49±0.26]nmol/L and [4.13±0.55]pmol/L,t=-0.240 and -0.260,respectively,P＜0.05 or 0.01) .In the T2DM group,T3 and FT3 were negatively correlated with FPG,GA,HbA1c(For T3:r=-0.275,-0.318 and -0.453,respectively,Ps＜0.05;For FT3:r=-0.280,-0.291 and -0.336 ,respectively,Ps＜0.05).Conclusion In patients with abnormal glucose metabolism, thyroid hormone was influenced only when the glucose metabolism level reached a certain abnormal degree.

Objective To investigate the association of leptin receptor gene Gln223Arg polymorphism with metabolism syndrome and insulin resistance. Methods The genotypes of leptin receptor in 167 patients with metabolic syndrome and 216 healthy subjects were determined by polymerase chain reaction restriction fragment length polymorphism. The biochemical indicators were detected. Results The frequency of A alleles was significantly higher in patients with metabolic syndrome than in healthy subjects. The risk of metabolic syndrome in inviduals with allele A was 3. 302 folds of that with allele G( P<0.01 ). Compared with allele G, the patients withA allele had higher body mass index,blood pressure, blood glucose, insulin level, waist circumference, and more serious dyslipidemia. The risk of insulin resistance in patients with A allele was 3. 446 folds of that with allele G (P<0.01). Conclusions Leptin receptor gene Gln223Arg polymorphism is associated with an increased risk of metabolic syndrome and insulin resistance.

Objective To investigate the therapeutic effects of alendronate combined with Caltrate D on regional bone mineral density (BMD) in elderly type 2 diabetic women with osteoporosis. Methods Thirty-four elderly type 2 diabetic women with osteoporosis aged 60-79 years (average 68. 0±4.5 years), with body mass index (BMI) of (25.0±3.7) kg/cm2 and duration of diabetes (8.9 ±4.4) years were enrolled. At the basis of a comprehensive management, the patients were treated with alendronate combined with Caltrate D for 6 months. BMD of the lumbar spine and hip, several biochemical indexes were measured before and after treatment. Results After the 6 months treatment, the BMD of different regions at lumbar spine and hip all increased. The T value and BMD were significantly higher at lumbar spines than at hip (both P＜0.01). The differences of T value and BMD of different regions were significant (P = 0.003 and 0.005,respectively). BMD percent change at lumbar spine were L4 (44.7%) ＞ L3 (31.9%) ＞ L total (27.3 % ) ＞ L1 (20.0%) ＞ L2 (14.3 % ), and the BMD percent changes were significantly higher in L3 and L4 than in other regions at lumbar spine (P=0. 038 and 0. 008, respectively). The changes of T value and BMD were significantly higher in L3, L total, L1 and L4 than in L2 (T value: P=0. 036,0. 042, 0. 006 and 0. 004, respectively; BMD: P=0. 002, 0. 002, 0. 003 and 0. 001, respectively).Conclusions On the basis of comprehensive management, the 6 months treatment with alendronate combined with Caltrate D in elderly type 2 diabetic women with osteoporosis may achieve good therapeutic effect at lumbar spines, especially at the lower lumbar spines, while less effective at hip.

Objective To investigate the relationship between the resistance of the Klebsiella pneumoni-ae and the Klebsiella pneumoniae plasmid pNDM-LJ carrying blaNDM-1 by high-throughput DNA sequencing. Methods High-throughput DNA sequencing was carried out by the Illumina Miseq platform , and sequencing data were assembled by Edena software. Contigs were annotated by the RAST server and analyzed by the BLAST server. Results The plasmid pNDM-LJ was 54-kb in size with a GC content of 49%. The plasmid encoded 52 putative functional genes and belonged to the IncX3 group in incompatible classifications. Analysis of the plasmid sequence revealed high similarity with other IncX3 plasmids. The blaNDM-1 gene was located in a complicated gene environment possibly constructed by several transposition events. The 5′ and 3′ ends of the blaNDM-1 gene were adjacent to the ISAba125 and IS 26 respectively , forming a 10.8-kb transposon-like structure. Conclusion The plasmid pNDM-LJ carried the blaNDM-1 gene being resistant to carbapenems and played a possibly impor-tant role in transmission of blaNDM-1 in China.

Objective To observe the effect of recombinant human granulocyte/macrophage colonystimulating factor (rhGM-CSF) combined with nano-silver for deep burn degreen Ⅱ. Methods The burn model were done with Wistar rats. They were randomly divided into four groups , group A (n = 30): petrolatum treatment, group B(n = 30): nano-silver treatment, group C(n = 30): rhGM-CSF treatment, and group D(n =30): rhGM-CSF combined with nano-silver treatment. The healing rates of the four groups were observed on postburn day 1, 4, 7, 10, 14, 21. Meanwhile the levels of VEGF and EGF in serums were measured with ELISA. Results All groups started to heal on postburn day 10. Group A had inflammation obviously , and group D moderately. There were significant difference in the healing retes on postburn day 10 , 14, 21 between four groups (P < 0.05). The level of VEGF in group A peaked on postburn day 21 (25.76 ± 1.46)pg/mL, but the levels of VEGF in group B, group C and group D peaked on postburn day 14[(29.73 ± 1.58)pg/mL, (38.91 ± 2.38)pg/mL, (43.54 ± 1.28)pg/mL]. On postburn day 4, 7, 10, 14, 21, there were significant difference(P <0.05). The level of EGF peaked on postburn day 21 in all groups [(0.72 ± 0.14)ng/mL, (0.93 ± 0.13)ng/mL, (1.18 ± 0.16)ng/mL, (1.50 ± 0.15)ng/mL]. There were significant difference on postburn day 7, 10, 14, 21 between four groups (P < 0.05). Conclusions rhGM-CSF combined with nano-silver treatment could promote wound healing, and be better than rhGM-CSF and nano-silver singly.

Objective: To explore the relationship between 1eptin receptor gene Gln223Arg polymorphism and metabolism syndrome (MS) with its impact on cardiac structure and function.
Methods: Our research included 2 groups:MS group, n=167 patients with ifrst diagnosed MS without treatment in our hospital from 2005-10 to 2008-6 and Control group, n=216 healthy subjects from regular physical examination. Blood pressure, biochemical features, insulin levels and echocardiography were detected;leptin receptor Gln223Arg genotypes were measured by PCR-RFLP;the above indexes were compared between 2 groups.
