Myeloid differentiation factor MyD88 is a critical adaptor molecule that integrates and transduces intracellular signals in inducing the differentiation of dendritic cells (DCs).The domain regions within MyD88 was searched,it could potentially affect the function of dendritic cells and found that MyD88 aa155-171 motif not only regulate the activity of transcription factor NF-?B, but also control the production of cytokines and expression of costimulatory molecules. Indeed, aa155-171 motif deleted type MyD88 (MyD88155-171) transfected RAW264.7 cells exhibited the reduced NF-?B and AP-1 activity and interrupted the expression of CD86 and B7H1. Meanwhile, lower level expression of cytokines such as IL-12,IFN-? were also observed by means of cytokine array in MyD88-/-DC trasfected with MyD88155-171 as compared to the MyD88 transfected cells. Thus, aa155-171 motif inside MyD88 could affect the expression of costimulatory molecules, production of cytokines and transduction of Toll like receptor signal pathway, suggesting that this motif may play an important role in regulating responses of innate immune system.

OBJECTIVETo investigate the effect of early escharectomy on resting energy expenditure (REE) in severely burned patients dynamically with the metabolic monitoring and diagnostic system.
METHODSFifty-six adult male patients with severe burns were divided into early escharectomy (group A, n = 39, escharectomy within 5 PBDs) and non-early escharectomy (group B, n = 17, escharectomy after 5 PBDs) groups. The wounds of full thickness and deep partial thickness burn in the two groups were all excised and covered with allogeneic skin and autologous micro-skin in the first operation. The changes in REE were observed dynamically at the bedside of the patients with the metabolic monitoring and diagnostic system. The plasma contents of IL-6, IL-8, TNF-alpha and LPS from 9 patients in group A and 7 in group B were also determined dynamically.
RESULTSAll patients survived. The REE in both groups was elevated markedly, but REE in group A was lower compared with group B before and after escharectomy within 14 days. (P < 0.05). The plasma level of IL-6, IL-8, TNF-alpha and LPS in group A were obviously lower than those in group B (P < 0.05).
CONCLUSIONThe hypermetabolic response of burn patients with severe burns could be lowered by early escharectomy, and it seemed to be related to the decrease of the release of proinflammatory mediators.

OBJECTIVETo study the expression of ET receptor and the apoptosis after intervened with ET receptor antagonist in androgen-independent prostate cancer.
METHODSPC3, an androgen-independent prostate cancer cell line, was used. The expression of ETA and ETB receptor in PC3 was measured through RT-PCR. After intervened with selective ETA and ETB receptor antagonist, the apoptosis in PC3 was studied through flow cytometry and electron microscope.
RESULTSClear signal was obtained in PC3 for ETA receptor mRNA transcript, while the signal for ETB receptor mRNA transcript was very weak. The expression of ETA receptor mRNA was obviously reduced and the apoptosis of PC3 cell was observed after intervened with selective ETA receptor antagonist. There was no change after intervened with selective ETB receptor antagonist.
CONCLUSIONET-1 exerts its effects through the ETA receptor subtype and ETB receptor is silenced in PC3. The expression of ETA was reduced and the apoptosis was observed in PC3 when ETA receptor was blocked. It was dose-dependent.

Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification.

OBJECTIVETo evaluate the clinical validity of anti-thyroperoxidase antibody (anti-TPOAb) and anti-thyroglobulin antibody (anti-TgAb).
METHODSerum levels of anti-TPOAb and anti-TgAb were assayed using chemiluminescence immunoassay in 434 subjects, including 51 patients with Hashimoto's thyroiditis, 58 with Graves' disease, 68 with nodular goiter, 56 with thyroid adenoma and carcinoma, 56 with subacute thyroiditis, 65 with euthyroid non-thyroid endocrine disease, 35 with euthyroid non-thyroid autoimmune diseases, and 45 euthyroid controls.
RESULTSThe highest level and most positive results of serum anti-TgAb and anti-TPOAb were observed in patients with Hashimoto's thyroiditis (median 373 and 6 974 U/ml, positive rate 84.3% and 86.3%), followed by patients with Graves' disease (median 84 and 1 369 U/ml, positive rate 44.8% and 72.4%). Serum anti-TgAb and anti-TPOAb were also more common in patients with subacute thyroiditis and other autoimmune diseases than in the controls.
CONCLUSIONThe assay of serum anti-TPOAb and anti-TgAb by chemiluminescence immunoassy are useful in the differential diagnosis of autoimmune thyroid disease.

OBJECTIVETo evaluate the relationship between the incidence of abnormal thyroid function of newborns and maternal hyperthyroidism with antithyroid drug therapy.
METHODThe clinical data of 35 neonates born to mothers with hyperthyroidism from 1983 to 2003 in Peking Union Medical College Hospital were retrospectively analyzed. According to the maternal thyroid function and the antithyroid drugs taken during pregnancy, subjects were divided into different groups.
RESULTSThe proportion of abnormal thyroid function in newborn was 48.6% (17/35). The prevalences of primary hypothyroidism, subclinical hypothyroidism, hypothyroxinemia, and central hypothyroidism were 29.4%, 29.4%, 35.3%, and 5.9%, respectively. The incidence of abnormal thyroid function of neonates whose mothers did not take the antithyroid drugs (ATDs) until the third trimester of pregnancy was significantly higher than those without and with ATDs during the first or second trimester (P < 0.01). The incidence of abnormal thyroid function significantly increased in premature neonates, neonates whose mothers with modest or heavy pregnant hypertension, or neonates whose core serum thyroid-stimulating hormone or serum anti-thyroid peroxidase antibodies levels were abnormal.
CONCLUSIONThe risk of abnormal thyroid function of infants whose hyperthyroid mothers did not take ATDs until the third trimester of pregnancy may be increased. Prompt diagnosis and appropriate treatment of hyperthyroidism in pregnant women are essential for the prevention of neonatal thyroid functional abnormality.

OBJECTIVETo study the incidence, clinical features and related factors of propylthiouracil (PTU)-induced hepatic injury in patients with hyperthyroidism.
METHODSA prospective study were carried out in 70 patients of hyperthyroidism with normal liver function. Every patient was treated with PTU 300 mg/d until the thyroid functions recovered to normal, following by decease and maintenance PTU dose in period of six months. Liver function, including serum levels of alanine aminotransferase (ALT), alkaline phosphatase (ALP), aspartate aminotransferase (AST), total bilirubin (TBIL) and direct bilirubin (DBIL), thyroid function (serum thyroxine, triiodothyronine, free thyroxine, and free triiodothyronine and thyrotropin) and blood routine items were measured before therapy and once a month for six months after PTU therapy was begun.
RESULTSSixty-four cases of 70 patients completed the therapy for 6 months. Hepatic injury developed in 33 patients (51.6%). Asymptomatic, transient hepatic injury was shown in 22 patients (34.4%). Slight symptomatic hepatic injury occured in 6 cases (9.4%) and overt hepatic injury in 5 patients (7.8%) after PTU administration. However, all the patients who developed overt hepatic injury did not stop PTU. Hepatic function returned normal one month after stopping PTU. No one finally suffered from viral hepatitis and autoimmune hepatitis in patients of symptomatic and overt hepatic injury.
CONCLUSIONSPTU-induced symptomatic hepatic injury is not rare and usually develops within the first few months of PTU administration. Its clinical course is relatively benign. However, it may be difficult to predict its development, so all patients should be monitored for liver function test during the administration in early stage.
