The second part of (2008 edition)includes iodine deficiency disease,thyroditis and thyroid nodule.This guideline reaffirms the epidemic characteristics,the prevention and the management of iodine deficiency disease.It identifies the measurement of iodine nutritional status and the necessity of iodinized salt.It emphasizes the regular diagnosis and treatment of subacute and chronic thyroiditis,and also mentions the advancement on differential diagnosis and rational therapy of thyroid nodules.In addition,it gives some advices on the management of thyroid nodules in two special groups(pregnant women and children).

Thyroid-associated ophthalmopathy(TAO)is an organ specific autoimmune disorder affecting the life quality of patients.Glucocorticoids have been applied for many years in the treatment of TAO,though the side effects are the major concern.Recently,intravenous methylprednisolone pulse therapy is a novel and effective method for TAO treatment.Nevertheless this new strategy needs to be modified,and attention should be paid to the indications and contraindications in order to prevent liver damage when high dose methylprednisolone is applied.

Severe aplastic anaemia is a marrow failure syndrome characterized by pancytopenia and hypocellular bone marrow.Immunosuppressive therapy(IST)consisting of antithymocyte or antilymphocyte globulin (ATG) and cyclosporine has been recommended for children lacking HLA-matched sibling donor.For children unresponsive to initial immunosuppressive therapy or those who relapsed after first immunosuppressive therapy,they can choose repeat course of immunosuppressive therapy,allogeneic hernatopoietic stem cell transplantation,new drugs or clinical trials.And the prognosis has been greatly improved in recent years,dueing to the development of allogeneic hematopoietic stem cell transplantation and the application of new drugs such as eltrombopag.This article reviews researches advance in different therapies for children with relapsed or refractory severe aplastic anaemia,aimed at guaiding treatment methods.

Chronic atrophic gastritis (CAG) is the disease with the pathological features of gastric mucosa inherent glands atrophy, mucous membrane thinning, muscularis mucosa thickening, gastric acid secretion decreasing, or along with intestinal metaplasia or pseudopyloric metaplasia. TCM differential treatment has obvious advantages. Through the summary of the literature on CAG, the authors summarize the aspects of etiology and pathogenesis, syndrome differentiation characteristic and their relations with gastroscopic image, pathology, and Helicobacter pylori infection, with a purpose to provide references for TCM clinic.

Objective To investigate the relationship of hypoxia inducible factor-1 α(HIF-1α),tumor necrosis factor-α (TNF-α),hepatocyte growth factor (HGF) and cerebral infarction.Method Two hundred and twelve cases with acute cerebral infarction in the Fourth People's Hospital of Langfang from Jun.to Dec.2013 were divided into progressive cerebral infarction(PCI) group(n =105) and the stability of cerebral infarction (SCI) group (n =107).Meanwhile 100 healthy people were served as control group.Enzyme-linked immunosorbent assay(ELISA) was applied to detect the levels of HIF-1 α,TNF-α and HGF.The PCI group were divided into small groups according to nerve function or infarction lesion size,and the levels of HIF-1 α,TNF-α and HGF of each group.Result The levels of HIF-1 α,TNF-α,HGF in PCI group were (2.3 ± 1.3) ng/L,(4.0 ± 0.5) mg/L and (1.4 ± 0.3) μg/L,significantly higher than those in SCI group ((1.1 ± 0.5) ng/L,(3.1 ±1.3) mg/L and (0.7 ±0.4) μg/L;F=5.42) and control group((0.5 ±0.1) ng/L,(1.8 ±0.4) mg/L and (0.4 ±0.1) μg/L;F =3.14).Meanwhile,the levels of HIF-1 α,TNF-α,HGF in SCI group was significantly higher than that of the control group (F =1.32,P ＜ 0.05).The levels of HIF-1α,TNF-α,HGF in mild PCI group were significantly lower than those in moderate group and severe group,and those in moderate group was lower than those in severe group (F =0.93,4.32,2.31 ; P ＜ 0.01).The levels of HIF-1 α,TNF-α,HGF in small infarction group were (0.6 ± 0.4) ng/L,(2.7 ± 0.4) mg/L,(0.7 ± 0.4) μg/L,significantly lower than those in infarction group ((1.1 ± 0.5) ng/L,(4.4 ± 0.5) mg/L,(1.1 ± 0.2) μg/L; F =4.71,P＜0.05) and large infarction group((1.4 ± 0.6) ng/L,(4.8 ± 0.6) mg/L,(1.9 ± 0.5) μg/L; F =2.09,P＜0.05).The levels of HIF-1α,TNF-α,HGF in focal infarction group was significantly lower than that in large infarction group and the difference is statistically significant(F =2.45,P ＜0.05).Conclusion HIF-1 α,TNF-α and HGF serum levels in progressive cerebral infarction are significantly increased,which is related to the function defect and size of infarction.

[Summary] Epidemiologic evidence favors strong correlations between low thyrotropin(TSH) and high bone turnover, low bone mineral density ( BMD), and high fracture risk in hyperthyroid patients. Even subclinical hyperthyroidism, in which TSH is low and thyroid hormones are normal, is associated with osteopenia and osteoporosis. These evidences indicate that action of TSH on bone metabolism is independent of thyroid hormones and thus support the theory of the pituitary-bone axis. TSH plays its osteoprotective effect by binding TSH receptor on osteoclasts and inhibiting TNF-α expression. Physicians should screen the BMD in patients with overt and subclinical hyperthyroidism, especially the elderly, and make early diagnosis and better management for the underlying osteopenia and osteoporosis.

Objective To explore the reversion of astragaloside and NMDA receptor antagonist against the hyperphosphorylation of protein Tau induced by fetal intrauterine distress in neonatal rats.Methods The analysis of variance of factorial design was setted up two intervention factors which were fetal intrauterine distress (two levels:no disposition;a course of fetal intrauterine distress)and the drugs (three levels:iv Saline;iv astragaloside;iv MK -801).When the neonatal rats grew to 12weeks,the hippocampus was removed from the neonatal rats.Detected the content of glutamate in the hippocampus of rats by high performance liquid chromatography.The expression of protein Tau which includes p -AT8Ser202 and GSK -3β1H8 in the hippocampus of rats were detected by the methods of immunohistochemistry staining.Results Fetal intrauterine distress could significantly up -regulate the content of glutamate,which was not affected by MK -801,in the hippocampus of neonatal rats which was reduces by the astragaloside (P <0.05).And both influences presented subtracting effects (P <0.05).Fetal intrauterine distress and the drugs do not affect the total protein Tau in the hippocampus of rats (P <0.05).Fetal intrauterine distress could up -regulate the hyperphosphorylation of protein Tau in the hippocampus of neonatal rats which could be reduced by astragaloside and MK -801 (P <0.05).And the influences between fetal intrauterine distress and the drugs presented subtracting effects (P <0.05 ).Conclusion Our results indicate that fetal intrauterine distress reduce the hyperphosphorylation of protein Tau in neonatal rats though up -regulating the content of glutamate.GSK-3βis the key protein in this signaling pathway.

At present, there is no specific antidote for local anesthetic toxicity, which seriously hindered therapeutic efficts of clinical treatment. It is increasingly urgent for finding find the effective antidote to local anesthetic. This article at-tempts to interpret the molecular pharmacological mechanism from fat pool, energy metabolism, NO, ion channel and solubili-zation for the role of fatty acids in reversal of myocardial toxicity of local anesthetics. And the different characteristics of the structure and function of nano liposome and fat emulsion were compared.
