La alta prevalencia de hipotiroidismo subclínico en Chile puede deberse a que el límite superior normal de la hormona estimulante del tiroides (TSH) sérica es bajo. Personas con TSH levemente mayor al límite superior pueden ser metabólicamente similares a personas sanas. Se compararon marcadores de acción tiroidea (gasto energético en reposo [GER] y lipoproteína de baja densidad [LDL]) en adultos con hipotiroidismo subclínico leve y con función tiroidea normal con o sin tratamiento con levotiroxina. Se midió GER, perfil lipídico y tiroideo en personas sanas con función tiroidea normal (TSH ≥0,4-<4,5 µUI/ml; n=91); con hipotiroidismo subclínico leve (TSH ≥4,5-≤6,5 µUI/ml; n=5); y con hipotiroidismo clínico tratado con levotiroxina y TSH normal (n=13). Se analizó la LDL en 838 personas sanas con función tiroidea normal y 89 con hipotiroidismo subclínico leve de la Encuesta Nacional de Salud 2016/17 (ENS). El GER, ajustado por peso, sexo y edad, fue similar entre grupos (p=0,71). La LDL fue similar entre personas con función tiroidea normal e hipotiroidismo subclínico leve (91±24 vs. 101±17 mg/dl; p=0,67), y menor en hipotiroidismo tratado (64±22 mg/dl; p<0,01). La LDL no se asoció con TSH pero si inversamente con T4L en mujeres (r=-0,33; p=0,02; n=53). En la ENS, ambos grupos tuvieron similar LDL (p=0,34), la que se asoció inversamente con T4L en mujeres (r=-0,12; p=0,01; n=569) pero no con TSH. Personas sanas con función tiroidea normal y con hipotiroidismo subclínico leve tienen similar GER y LDL. Esto apoya la idea de redefinir el límite superior normal de TSH.
The high prevalence of subclinical hypothyroidism in Chile may be due to the low normal upper limit of serum thyroid-stimulating hormone (TSH). People with TSH slightly higher than the upper limit may be metabolically similar to healthy people. Thyroid action markers (resting energy expenditure [REE] and low-density lipoprotein [LDL]) were compared in adults with mild subclinical hypothyroidism and with normal thyroid function with or without levothyroxine treatment. REE, lipid and thyroid profile were measured in healthy people with normal thyroid function (TSH ≥0,4-<4,5 µUI/ml (n=91); with mild subclinical hypothyroidism (TSH ≥4,5-≤6 µUI/ml; n=5); and with clinical hypothyroidism treated with levothyroxine and normal TSH (n=13). LDL was analyzed in 838 healthy people with normal thyroid function and 89 with mild subclinical hypothyroidism from the 2016/17 National Health Survey (NHS). REE, adjusted for weight, sex and age, was similar between the groups (p=0,71). LDL was similar between people with normal thyroid function and mild subclinical hypothyroidism (91±24 vs. 101±17 mg/dl; p=0,67), and lower in treated hypothyroidism (64±22 mg/dl; p<0,01). LDL was not associated with TSH but was inversely with FT4 in women (r=-0,33; p=0,02; n=53). In the NHS, both groups had similar serum LDL (p=0,34), which was inversely associated with FT4 in women (r=-0,12; p=0,01; n=569), but not with TSH. Healthy people with normal thyroid function and mild subclinical hypothyroidism have similar REE and LDL. These results support the idea of redefining the normal upper limit of TSH.

ObjectiveTo observe the clinical efficacy of modified Yigongsan combined with multi-enzyme tablets and bifidobacterium triple live powder on infantile anorexia with spleen-stomach Qi deficiency syndrome. MethodA total of 112 infantile patients anorexia with spleen-stomach Qi deficiency syndrome treated at Hebei Provincial Hospital of Traditional Chinese Medicine from January 2022 to June 2023 were enrolled and divided into a control group and an observation group， with 56 cases in each group， according to a random number table. Children in the control group were treated with multi-enzyme tablets and Bifidobacterium triple live powder， while those in the observation group were treated with modified Yigongsan in addition to the treatment in the control group. During the study， one case dropped out in the control group and two cases dropped out in the observation group. The clinical efficacy of the two groups of children was compared， including changes in traditional Chinese medicine （TCM） syndrome scores （main symptoms， secondary symptoms， tongue， and pulse）， time to restore normal food intake， and increase in body weight. Changes in calcium， iron， zinc levels， hemoglobin， and albumin levels before and after treatment， as well as changes in gastrointestinal hormones such as gastrin and motilin， vasoactive intestinal peptide， somatostatin， neuropeptide Y， orexin， and leptin， were observed. The occurrence of adverse reactions in the two groups of children during the study was also recorded. ResultThe total effective rate of children in the control group after treatment was 85.19% （46/54）， while that in the observation group was 98.15% （53/54） （χ2 =5.939， P<0.05）. Compared with the control group， the time for food intake to return to normal in the observation group was shorter， and the increase in body weight was greater （P<0.05）. Compared with the results before treatment， the TCM syndrome scores （main symptoms， secondary symptoms， tongue， and pulse） in both groups of children significantly decreased， while the levels of calcium， iron， zinc， hemoglobin， albumin， gastrin， motilin， neuropeptide Y， and orexin increased， and the levels of vasoactive intestinal peptide， somatostatin， and leptin decreased （P< 0.01）. Compared with the control group after treatment， the improvement in the above indicators in the observation group was more significant （P<0.01）. The incidence of adverse reactions in the two groups of children during the treatment period was similar， and the difference was not statistically significant. ConclusionModified Yigongsan combined with multi-enzyme tablets and Bifidobacterium triple live powder is highly effective in treating infantile anorexia （spleen-stomach Qi deficiency syndrome）. After treatment， symptoms of the children were improved，appetite and food intake increased， gastrointestinal function was improved， body weight increased， and adverse reactions were few， indicating that the treatment was safe and reliable.

As color doppler ultrasound listed as the thyroid to regular physical examination project, the positive detection rate of benign and malignant thyroid diseases has increased year by year. The population of patients after thyroid surgery is getting larger and larger, however, the research on how to replace the absent thyroid with exogenous thyroid hormone is not perfect. As the switch of thyroid hormone activation and deactivation, deiodinase plays an important role in maintaining the internal environment of human body. The expression of these enzymes will change with the different needs of each organ in the individual. In the past, many authors have made a detailed description of deiodinase in basic medicine, but the principle of action in clinical aspects is relatively lacking. In this paper, the mechanism of deiodinase was reviewed through literature reading, to explore the basic principle of deiodinase in exogenous thyroid hormone supplementation after thyroid surgery.

Objective:To analyze the clinical and genetic characteristics of congenital hypogonadotropic hypogonadism (CHH) in boys.Methods:Cross-sectional study.Clinical data, laboratory data and genetic results of boys who were genetically diagnosed with CHH at the Department of Endocrinology of Shenzhen Children′s Hospital from December 2019 to February 2023 were collected in this retrospective study.Their clinical manifestations, hormone levels and gene mutations were analyzed.The non-normal distribution was represented by the median.The rank sum test was used to compare the non-normal distribution data between the two groups.Results:A total of 27 boys were genetically diagnosed with CHH, with the age at first diagnosis ranging from 0.3 to 16.6 years old.All these children presented with micropenis (100%), of whom 16 were complicated with cryptorchidism (59.3%), 9 with microrchidia (33.3%), 7 with simple micropenis (25.9%), and no had simple cryptorchidism.Three children had cardiovascular dysplasia.The median of basal luteinizing hormone(LH) level was 0.09 IU/L, and 92.5%(25/27) of children had the basal LH level below 1.00 IU/L.The median of peak LH level after gonadotropin-releasing hormone(GnRH) stimulation was 1.42 IU/L, and 96.2%(26/27) of children had the peak LH level below 4.00 IU/L.The median of serum inhibin B was 41.15 μg/L, and the median of serum anti-Müllerian hormone(AMH) was 12.62 mg/L.The serum AMH level of children with cryptorchidism was significantly lower than that of children without cryptorchidism (10.02 mg/L vs.50.50 mg/L, P<0.05). A total of 12 gene mutations were detected in the 27 children, of which 1 was biallelic mutation.The most common gene mutations were in CHD7 and ANOS1 genes (7 children each, both accounting for 51.8%), followed by FGFR1 gene (3 children, 11.1%). After short-term treatment by GnRH pump or subcutaneous injection of recombinant human follicle stimulating hormone in 4 children, the levels of serum inhibin B and AMH increased significantly, and the testicular volume also increased.

BACKGROUND:Previous studies have shown that human dental pulp stem cells have good osteogenic differentiation potential and are potential seed cells in bone tissue engineering,and the effect of recombinant human growth hormone on the proliferative osteogenic differentiation of human dental pulp stem cells is still unclear. OBJECTIVE:To explore the effect of recombinant human growth hormone on the proliferation and osteogenic differentiation of human dental pulp stem cells. METHODS:Human dental pulp stem cells were isolated and cultured by tissue block culture method.After screening according to the drug concentration gradient,recombinant human growth hormone containing 10,100,250,500,1 000 μg/L was selected as the experimental group,and 0 μg/L without recombinant human growth hormone was selected as the control group.CCK-8 detection reagents were used on days 1,3,5,and 7 after the drug intervention to detect the proliferation of human dental pulp stem cells.Different concentrations(10,100,250,500,and 1 000 μg/L)of recombinant human growth hormone were added to the osteogenesis induction solution to intervene in human dental pulp stem cells.Alkaline phosphatase activity was detected by alkaline phosphatase staining and semi-quantitative analysis on day 7 of mineralization induction.The mRNA expression levels of osteogenic gene type I collagen,osteocalcin and Runt-related transcription factor 2 were detected by fluorescence quantitative RT-qPCR.Alizarin red staining was performed on day 14 of mineralization induction to detect osteogenic mineralized nodules. RESULTS AND CONCLUSION:(1)CCK-8 assay results showed that from the third day of intervention,the 100,250,500,1 000 μg/L recombinant human growth hormone group could promote the proliferation of human dental pulp stem cells compared with the control group(P<0.01).(2)The alkaline phosphatase activity of human dental pulp stem cells in the 100,250,and 500 μg/L recombinant human growth hormone group was significantly increased compared with the control group(P<0.01).The number of alizarin-stained mineralized nodules in human dental pulp stem cells in the 100,250 μg/L recombinant human growth hormone group was significantly increased compared with the control group(P<0.01).Compared with the control group,the mRNA expression of type I collagen and osteocalcin increased in the 250 μg/L recombinant human growth hormone group(P<0.05,P<0.01).mRNA expression of Runt-associated transcription factor 2 increased in the 100 and 250 μg/L recombinant human growth hormone groups(P<0.01).(3)According to the above results,recombinant human growth hormone at a concentration of 250 μg/L is a more suitable concentration to promote the proliferation and osteogenic differentiation of human dental pulp stem cells.

BACKGROUND:Glucocorticoids can inhibit the expression of hub genes in the parathyroid hormone type Ⅰ receptor(PTH1R)/protein kinase A(PKA)signaling axis and interfere with the osteogenic and angiogenic differentiation of bone marrow mesenchymal stem cells,leading to the disruption of blood supply in bone and bone tissue structures.Previous studies of the research team showed that Gubitongxiao granules can induce blood vessel formation and inhibit osteoblast apoptosis,which has a certain effect on the prevention and treatment of steroid-induced femoral head necrosis. OBJECTIVE:To observe the therapeutic effect of Gubitongxiao granules in a mouse model of steroid-induced femoral head necrosis,and to explore its mechanism from the PTH1R/PKA signaling axis. METHODS:An animal model of steroid-induced necrosis of the femoral head was established by intraperitoneal injection of lipopolysaccharide and gluteal muscle injection of prednisolone acetate.After identification by nuclear magnetic resonance method,60 mice that were successfully modeled were divided into model group,Gubitongxiao granule group and Tongluo Shenggu capsule group,with 20 mice in each group.Another 12 normal mice were used as control group.The corresponding groups were intragastrically given the corresponding drugs for 12 weeks,and then the samples were taken under anesthesia.Histomorphology of femoral head samples was observed by hematoxylin-eosin staining.Enzyme-linked immunosorbent assay was used to detect the serum levels of bone alkaline phosphatase,type Ⅰ amino-terminal extension peptide,parathyroid hormone,osteocalcin and alkaline phosphatase.Western blot and RT-qPCR were used to detect PTH1R,PKA,myocyte enhancer factor 2,sclerostin and guanylate-binding protein activity-stimulating peptide at protein and gene expression levels,respectively. RESULTS AND CONCLUSION:Gubitongxiao granules may reduce the serum PTH level in mice,inhibit the activation of the PTH1R/PKA signal axis,further up-regulate the protein expressions of sclerostin and myocyte enhancer factor 2,and increase the levels of bone alkaline phosphatase,type Ⅰ amino-terminal extension peptide,osteocalcin and alkaline phosphatase in mice,thus improving femoral head necrosis,which is comparable to the intervention effect of Tongluo Shenggu capsules.It is speculated that Gubitongxiao granules may prevent and treating hormonal femoral head necrosis by regulating the PTH1R/PKA signaling axis.
