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).

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.

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.

Cellular functions like proliferation,differentiation,migration,morphogenesis and apoptosis are modulated by the extracellular matrix.Integrins are the prototypic heterodimeric transmembrane matrix receptors with competing affinities for individual extracellular matrix ligands.The intracellular integrin domain clusters cytoplasmic proteins into focal adhesion plaques for bidirectional(outside-in and inside-out) signaling.Integrin-linked kinase(ILK) is an intracellular serine/threonine protein kinase that interacts with the cytoplasmic domains of ?-integrins.ILK organizes the connections of the extracellular matrix via integrins to the cytoskeleton and is involved in adhesion plaque signaling,and it plays a crucial role in the pathogenesis of chronic renal fibrosis.High glucose induces the upregulation of the synthesis and activity of ILK in cultivated mouse podocytes and mesangial cells.The ILK protein level is significantly increased in diabetic glomeruli.ILK activity is likely to provide the basis for an effective therapeutic method for diabetic nephropathy.This review gives an introduction of ILK structure and function,followed by a summary of our current understanding of ILK in diabetic nephropathy with a special focus on glomerular cell-matrix interaction.

Objective　To observe the effects of epithelial growth factor (EGF) and basic fibroblast growth factor (bFGF) on wound healing of the penetration keratoplasty (PKP) with autograft in rabbits. Methods　After the establishment of penetrating keratic autograft model on 24 rabbits, they were equally divided into EGF-, bFGF-, EGF+bFGF-treated and control groups. The wound healing of all the animals were observed with healing intensity, liquid scintillation counter, AgNORs staining, VG staining and transmission electron microscopy. Results　①EGF, bFGF, and EGF+bFGF increased the limiting pressure of the wounds and the 3H-TdR incorporation. ②The fibroblast cells and its secreting proliferative collagen in both the bFGF group and EGF+bFGF group were more well-arranged. Conclusion　①EGF, bFGF, EGF+bFGF can obviously elevate the intensity of wound healing after PKP and enhance the synthesis of DNA. ②The effect of this agent combination is just as the same as bFGF applied alone 14 d after the operation. ③bFGF can improve the quality of wound healing after PKP.

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.

Anaplastic thyroid cancer (ATC) is a rare but highly lethal form of thyroid cancer.The original ATC guidelines were published by American Thyroid Association in 2012.The guidelines recommend that once the diagnosis of ATC has been verified,rapid evaluation and establishment of treatment goals are imperative,and a multidisciplinary management is required.Radical surgical resection and high doses of external beam radiotherapy are important factors associated with prolonged survival.
