The most common clinical manifestations of Hashimoto’s thyroiditis (HT) are goiter and hypothyroidism. The biochemical thyroid function varies quite widely among patients. Anti-TPO antibodies (TPOAbs) are the most sensitive index to screen HT. The thyroid function deteriorates gradually, and the hypothyroidism is the permanent sequeala of HT. The natural history of HT in children and adolescents is not fully known, and monitoring of thyroid function for all patients should be long-term. Children with hypothyroidism should be treated with levothyroxine replacement therapy.

Because of their physiological and anatomical immaturity, premature infants are prone to disorders of glucose metabolism. In the ifrst week after birth, infants have the greater risk of abnormal glucose metabolism. Compared with term infants, the glucose/insulin homeostasis of preterm infants is very different. This article reviewed the characteristics of glycometabolism in premature infant and the methods of glucose test.

Obesity in children and adolescents has become a public health problem of global attention.Although children obesity has less significant cardiovascular events,many obese children have early vascular lesion and endothelial dysfunction.Therefore,the risk factors of cardiovascular injury should be evaluated and intervented as soon as possible.

Objective To study the significance of thyroid stimulating antibody (TSAb) and thyroid stimulating-blocking antibody (TSBAb) in children with Graves' disease (GD) or Hashimoto's thyroiditis (HT).Methods Five hundred and twenty-seven cases of serum from 180 children with autoimmune thyroid disease (AITD) children were divided into 282 cases of GD and 245 cases of HT.According to the status of thyroid function,they were divided into 157 cases of hyperthyroidism,91 cases of hypothyroidism and 279 cases of normal thyroid.GD group was subdivided into 127 GD hyperthyroidism and 155 GD remission;HT group was subdivided 30 HT hyperthyroidism,124 HT remission and 91 HT hypothyroidism.Seventy-nine healthy children were taken as the healthy control group.Free triiodothyronine(FT3),free thyroxine(FT4) and sensitive thyroid stimulating hormone(TSH) were detected by chemoluminescence.Serum TSAb and TSBAb were detected by serum TSAb or TSBAb enzyme linked immunosorbent assay (ELISA),respectively.The differences in TSAb and TSBAb among each group were compared and analyzed of find out the relationship between TSAb and TSBAb was performed.Beside,the correlation between TSAb and TSBAb with FT3,FT4,and TSH were analyzed.Results (1) TSAb levels were significant (F =11.995,all P =0.000):the GD group (0.727 ± 0.157) ＞ HT group (0.605 ± 0.148) ＞ healthy control group (0.350 ± 0.105);the difference was significant(F =109.165,P =0.000) among hyperthyroidism group (0.745 ± 0.169) ＞ normal thyroid group (0.647 ± 0.153) ＞hypothyroidism group(0.612 ±0.144) ＞healthy control group (0.350 ±0.105);the difference was significant(F=156.712,P =0.000) in the GD hyperthyroidism group(0.747 ±0.17) ＞ GD remission group (0.640 ± 0.16) ＞ healthy control group (0.350 ± 0.105);the difference was significant (F =109.165,P =0.000) in the HT hyperthyroidism group(0.739 ±0.140) ＞HT remission group(0.655 ±0.135) ＞ HT hypothyroidism group(0.612 ± 0.140) ＞healthy control group (0.350 ±0.105).(2) TSBAb levels were significantly different(F =15.610,P =0.000):the HT group(0.704 ±0.633) ＞ GD group(0.567 ±0.178) ＞ healthy control group (0.334 ±0.104);the difference was significant(F =13.311,P =0.000) in the hypothyroidism group (0.693 ± 0.125) ＞ remission group (0.648 ±0.446) ＞hyperthyroidism group(0.562 ±0.181) ＞healthy control group(0.334 ±0.104);the difference was significant(F =19.269,P =0.000) in the GD remission group (0.672 ±0.572) ＞ GD hyperthyroidism group (0.550 ± 0.187) ＞ healthy control group (0.334 ± 0.104);HT hypothyroidism group (0.693 ± 0.725) was higher than HT hyperthyroidism group(0.618 ±0.142) and HT remission group (0.619 ±0.199),the difference was not significant between HT hyperthyroidism group and HT remission group(F =12.208,P =0.000).(3) TSAb level was positively correlated with TSBAb,FT3 and FT4(r =0.162,0.091,0.194,all P ＜ 0.05) and was negatively correlated with TSH (r =-0.224,P ＜ 0.05).TSBAb levels were negatively correlated with FT3 (r =-0.155,P ＜ 0.05) and was positively correlated with TSH (r =0.131,P ＜ 0.05).Conclusions Thyroid function was related to the serum levels of TSAb and TSBAb.TSAb and TSBAb could be regarded as an important predictive index for children with AITD during the treatment period.

With the obesity epidemic,children and adolescents with type 2 diabetes mellitus(T2DM)signifi-cantly increased throughout the world,screening and diagnosis of T2DM in the high - risk population is very important. In addition to lifestyle modification,the recommended optimal pharmacologic treatment of children and adolescents with T2DM is Metformin and Insulin. To reduce the risk of cardiovascular diseases,should fully understand the comorbidities and complications of T2DM,and take better assessment and management.

Objective To study clinical value and significance of thyroid receptor stimulating antibody (TSAb) and thyroid stimulating-blocking antibody (TSBAb) on diagnosis and treatment for children with Graves’disease (GD) and Hashimoto’s thyroiditis (HT). Methods Eighty-eight children with autoimmune thyroid disease (AITD) and treatment time less six months were divided into GD group (n=55) and HT group (n=33). Thirty-eight healthy children were used as control (Normal group). Human serum TSAb ELISA kit and human TSBAb ELISA kit were used to detect the serum TSAb and serum TSBAb in three groups. The serum levels of TSAb and TSBAb were compared between three groups. The correla? tion between TSAb and TSBAb, TSAb/TSBAb and free triiodothyronine three (FT3), free thyroxine (FT4), ultra sensitive thy?roid stimulating hormone (TSH) were analyzed. Results The serum level of TSAb was significantly higher in GD group than that of HT group and Normal group (P<0.05). The serum level of TSBAb was significantly higher in HT group than that of Normal group (P<0.05). There was no significant correlation between serum TSAb and serum TSBAb (P>0.05). There were no significant correlation between serum TSAb, TSBAb and FT3, FT4, TSH (P>0.05). Conclusion TSAb and TSBAb are related to the pathogenesis of GD and HT in children. TSAb and TSBAb have an important clinical value in the diagnosis and treatment for children with GD and HT.

Aim To investigate the effect of small inter-ference RNA-mediated silcencing of the Bmi-1 gene on cell invasion and metastasis in human nasopharyngeal carcinoma cell line CNE-1 . Methods Chemically syn-thesized siRNA targeting the Bmi-1 gene was transfect-ed into CNE-1 cells, which had high invasive and me-tastatic potential. The expression of Bmi-1 mRNA and protein were detected by quantative Real-time PCR and Western blot, respectively. The effects of Bmi-1 knockdown on CNE-1 cells migration and invasion were analysied by Transwell migration assay and Matrigel in-vasion assay. Results Transfected with Bmi-1 siRNA significantly down-regulated the expression of Bmi-1 mRNA and protein as compared with the control group. CNE-1 cells transfected with Bmi-1 siRNA had lower levels of invasion and migration capacity than cells in the control group. Conclusion SiRNA-media-ted silencing of the Bmi-1 gene could significantly in-hibit cell migration and invasion in human nasopharyn-geal carcinoma cell line CNE-1 .

Objective:To explore the correlation between Coronin-1 and non-Mtb induced autophagy in macrophages and its possible signal pathway.Methods: The pEGFP-C1-Coronin-1 plasmids encoding the over-expression of Coronin-1 and pGenesil-1-Coronin-1 plasmids encoding the siRNA of Coronin-1 gene were constructed and transfected into RAW264.7 respectively in order to obtain their stable transfected cell line ( RAW264.7-Cor.Plus and RAW264.7-Cor.Minus ).After the RAW264.7, RAW264.7-Cor.Plus and RAW264.7-Cor.Minus group cells were treated with complete medium, starvation, Rapamycin and Cyclosporine A respectively,the transcription level of Beclin-1 gene was detected by RT-PCR,and the protein expression level of Coronin-1 and Beclin-1 and the ratio of LC3BⅡ/LC3BⅠwas analyzed by Western blot.Results:The over-expression plasmids,the siRNA plasmids and their stable transfected cell lines which can over-express the Coronin-1 or inhibit its expression were successfully constructed.When the three groups cell treated with blank control,the ratio of LC3BⅡ/LC3BⅠwas found that:RAW264.7-Cor.Minus>RAW264.7>RAW264.7-Cor.Plus significantly,and the transcription level of Beclin-1 gene and its protein detected by RT-PCR and Western blot respectively showed the same trend with the ratio of LC3BⅡ/LC3BⅠ;When the three groups cell treated with starvation,the ratio of LC3BⅡ/LC3BⅠjust become the opposite of the first result significantly;When the RAW264.7 cells treated with Rapamycin, the expression of Coronin-1 was inhibited significantly.The ratio of LC3BⅡ/LC3BⅠin the RAW264.7-Cor.Plus group treated with Rapamycin and CsA respectively was higher than its corresponding control treatment group.Conclusion:There is a correlation between Coronin-1 and non-Mtb induced cell autophagy in macrophage.In the nutrition sufficient condition, Coronin-1 can inhibit autophagy;in the hungry condition,Coronin-1 can promote autophagy.The regulation of autophagy by Coronin-1 may be associated with mTOR and calcium signaling pathway.

ObjectiveTo objectively evaluate the clinical efficacy of three-step acupuncture-cupping therapy for cervicogenic headache.MethodSixty patients were randomly allocated to treatment and control groups. The treatment group received three-step acupuncture-cupping therapy and the control group, conventional acupuncture based on “Acupuncture Therapeutics”. Both groups were treated for three courses (10 days as acourse with two days of rest between two courses) and then the clinical therapeutic effects were evaluated. The evaluation included the overall therapeutic effect on the symptoms, the VASscore and the follow-up recurrence rate at six months after treatment.ResultThe total efficacy rate was 96.7% in the treatment group and 83.3% in the control group; there was a statistically significant difference between the two groups (P<0.01). A follow-up of six months after treatment in the two groups showed that the recurrence rate was 16.7% in the treatment group and 46.7% in the control group;there was a statistically significant difference between the two groups (P<0.05).ConclusionThree-step acupuncture-cupping therapy has a definite effect on cervicogenic headache. Its immediate and long-term effects are superior to those of conventional acupuncture. The recurrence rate in six months is lower in this therapy than in conventionalacupuncture.

Objective To investigate the possible association of circulating components of GH-IGFs-IGFBPs system with the GHR-exon 3 genotype in idiopathic short stature (ISS) children. Methods Genomic DNA was extracted and isolat-ed from peripheral leukocytes in 108 ISS children. GHR-exon 3 polymorphism was analyzed with multiplex poly-merase chain reactions (PCR) assay. According to the results of genotype, ISS children were divided into GHRfl group and GHRd 3 group. The height and weight were recorded in two groups. The body mass index (BMI) and BMI standard deviation score (SDS) were measured. The serum levels of insulin-like growth factor (IGF)-1, IGF-binding protein (IGFBP)-3, IGF-1 SDS and IGFBP3 SDS were calculated. GH stimulation test was used to measure the serum GH peak value. Fifty-five ISS chil-dren were treated with recombine human GH [0.15 IU/(kg·d)] for three months to analyse the association of IGF-1 response of GH treatment and genotypes. Results There were 63 GHRfl and 45 GHRd3 in 108 ISS children. There were no signifi-cant differences in BMI, IGF-1, IGFBP3, GH peak, IGF-1 SDS and IGFBP3 SDS between two groups (P>0.05). Multiple stepwise regression analysis showed that age, IGFBP3, lg (BMI) and lg (GH peak) were influencing factors of lgIGF-1 (P<0.05). In 55 ISS children treated with rhGH, there were 34 cases of GHRd3. The differences of △IGF-1 and △IGF-1 SDS were higher in GHRd3 group than those of GHRfl group (n=21). Conclusion The GH sensitivity may be a risk factor in ISS children, which may not be related with GHR polymorphism.
