Thyroid hormones (TH) play an imp or tant role in the development and maturity of the mammalian brain. Maternal TH de ficiency, even subclinical hypothyroidism, leads to poor neurodevelopment of the fetus. Screening of pregnant women for hypothyroidism is recommended. Identific ation of the TH-responsive genes in the developing brain and investigation on t heir functions are helpful to provide insights into the molecular mechanisms by which TH influence brain development.

Objective To investigate the correlation between the glycosylated hemoglobin (HbA1c) detection data and hemo‐rheological indicators in diabetes patients to provide reference basis for its treatment and prevention .Methods One hundred and forty‐two patients with typeⅡdiabetes mellitus(T2DM ) in the hospital were selected as the research subjects and divided into the A group(69 cases ,better control) and B group(73 cases ,poor control) according to the HbA1c detection results .Contemporaneous 70 healthy individuals undergoing physical examination were selected as the control (C group) .The detection results of HbA1c ,hemo‐rheology and biochemical indexes were performed the contrastive analysis .Results Except hematocrit and erythrocyte deformation index without statistical difference among 3 groups(P>0 .05) ,the other hemorheologic indicators had statistical differences among 3 groups(P<0 .05) .No matter the HbA1c level in T2DM patients ,the hemorheological indexes ,triglyceride and total cholesterol were higher than those in the healthy people ,When the HbA1c leve was poorly controlled ,the increase degresss of various indexes were more significant .Conclusion The abnormality of hemorheology indices exist in most of the patients with diabetes mellitus .It is recommended that clinic should monitor the HbA1c level for long term and strictly observe the change of hemorheology indexes to guide the clinical treatment for reaching the effects of early vascular protection and prevention of diabetic complications .

Thyroid-stimulating hormone receptor(TSHR)is an important autoantigen whose cleavage and shedding can induce autoimmunity.The TSHR is the main functional receptor of the thyroid.The shedding of the ? subunit plays an important role in the forming of TSAb and balancing between TSAb and TBAb.Research on the cleavage and shedding of the TSHR extracellualar domain helps to gain a deep insight into the structure and function of TSHR,illuminate the pathogenesis of autoimmune thyroid disease and find out a new therapy.The structure of TSHR,the mechanism and the significance of its cleavage and shedding are reviewed in this article.

This paper introduces the nursing care for 36 patients with framework exposure in auricular reconstruction by temporal superficial fascia flaps combining with split skin grafts transplantation,such as pre-and post-operative behavioral in-struction,psychological care,and close observation of blood circulation of reconstructed auricular. The patients' wounds healed up well and all the split skin grafts survived successfully. No infection and stent exposure occurred once more. The appear-ance of the reconstructed auricular was pleasing too. It is suggested that high quality of pre-and post-operative nursing,care-ful health education and psychological care be beneficial for the successful repair of framework exposure after auricular recon-struction.

Many flaviviruses are emerging and reemerging pathogens, such as West Nile virus (WNV), dengue virus (DENV), yellow fever virus (YFV), and Japanese encephalitis virus. Serological assay is the dominant method for diagnosis of flavivirus infections in human. Because antibodies generated during flavivirus infections cross-react with other flavivirus members, plaque reduction neutralization test (PRNT) is the only available assay to determine the infecting flavivirus type.Since PRNT requires culturing raw viruses, it must be performed in biosafety level-3 or level-4 containment for many flaviviruses, and takes more than ten days to complete. To overcome these problems, we have developed flavivirus viral-like particles (VLPs) that could be used to replace raw viruses in the neutralization assay. The VLPs were prepared by trans packaging a luciferase-reporting replicon with viral structural proteins. This novel assay involves three simple steps: (ⅰ) VLPs from a panel of flaviviruses are incubated with flavivirus-infected sera at 37℃ for 1 h; (ⅱ)the neutralized VLPs are used to infect Vero cells; and (ⅲ) the infected cells are measured for luciferase activities at 22 h post-infection. The virus type whose VLP is most efficiently neutralized by the serum specimen (as quantified by the luciferase activities) is the etiologic agent. As a proof-of-concept, we show that a WNV-infected mouse serum neutralized the WNV VLP more efficiently and selectively than the DENV and YFV VLPs. Our results demonstrate that the VLP neutralization assay maintains the "gold standard" of the classic PRNT; importantly, it shortens the assay time from ＞10 days to ＜1 day, and can be performed in biosafety level-2 facility.

Objective To sum up the experience of a large-scale aero transportation of mass casualties away from the quake-hit region to distant cities,and to provide reference for medical transportation of mass casualties.Method The study analyzed the aero medical transportation of 3 482 casualties from quake-hit region treated in West China Hospital of Siehuan University and other seven hospitals in Sichuan Province to other provinces from 22 May 2008 to 3 June 2008.The influencing factors of aero medical transportation were discussed,including selection standard of patients,preparation of staff and mcterials before transportation,management during transportation.The selection standards were:patients with stable condition after orthopedic operation and craniocerebral operation,and patients with passage of gas by anus after abdominal operation 5 days.Results Total of 3 482 casualties were transported in 99 times to 19 cities including Guangzhou,Shanghai,Shenyang,only 8 victims felt a little bit uncomfortable during flight,and recovered soon after management.Conclusions Total of 3 482 patients were safely transported.Strict selection of patients,comprehensive planning and monitoring,and psychotherapy are important for aero medical transfer.

Myogenic potentials evoked by air conducted sound (ACS), bone conducted vibration (BCV) or galvanic pulses can be recorded with surface electrodes over contracted muscles. These myogenic potentials are of vestibular origin (utricle and saccule) and so these potentials are called vestibular evoked myogenic potentials (VEMPs). Since the vestibular system has projections to many muscle systems, there are many such VEMPs. In this review, we discuss the generated origin, response pathway, waveform characteristics and clinical application of ocular vestibular-evoked myogenic potential (oVEMP).
