Thyroid microsomal antigen-antibody(TMAg-Ab)system plays an important role in the pathogenesis of autoimmune thyroid diseases.TMAb are involved in the complementmediated cytotoxicity and antibody-dependent cytotoxicity,resulting in thyroid follicle epithelial cell and basement membrane injury,followed by thyroiditis and hypothyroidism,and they may also cause hyperthyroidism through some unknown mechanisms.In recent years,indirect hemagglutination,radioimmunoassay and enzyme-inked immunosorbent assay have been used to detect TMAb in thyroid disease patients'sera,indicating the incidence as high as 90%.Measurements of T3,T4 and TSH alsoreveal that serum TMAb level is related with the variation of T3,T4 and TSH.It ispostulated that TMAg might be the lipoprotein on smooth endoplasmic reticulum ofthyroid follicle epithelial cell.Due to the difficulties to purify TMAg,its nature stillremains unclear.

The serum thyroid microsomal antibodies (TMAb) and thyroglobulin antibodies (TGAb) were measured in 103 normal persons and 183 patients with different thyroid diseases by enzyme-linked immunosorbent assay (ELISA). The serum T3 and T4 were also tested. The results showed that the incidence of these two autoantibodies were obviously increased in Hashimoto's thyroiditis, hyperthyroidism and hypothyroidism, and normal in simple goiter and thyroid adenoma. The TMAb and TGAb levels in subacute thyroiditis and thyroid cancer were moderately increased. There were also a negative correlation between TMAb and T3, T4, TGAb and T4 in Hashimoto's thyroiditis.

BACKGROUND:Repair of large-area burns and severe post-traumatic skin defects has always been urgent clinical breakthrough technology bottleneck. With the development of tissue engineering, epidermal stem cel s are increasingly being used in tissue engineering, cel replacement therapy and genetic engineering. Therefore, the isolation and identification of epidermal stem cel s is becoming the research focus of concern.
OBJECTIVE:To review the research progress in biological markers of epidermal stem cel s.
METHODS:The Chinese Biomedical Literature database, CNKI database, China Academic Journals Ful-text database, PubMed database and EMbase database were retrieved for articles about specific markers of epidermal stem cel s using the keywords of“epidermal stem cel s, integrin, keratin, P63, CD71, telomerase, ACE, cx43, hoechst”in Chinese and English. Older theoretical perspectives and repetitive research were excluded.
RESULTS AND CONCLUSION:Final y, only 40 articles were included in result analysis. Epidermal stem cel s bring a new source for skin tissue repair. Epidermal stem cel s distribute in the fol icle eminence and basal layer of the epidermis. About 4%cel s in the basal layer, however, are stem cel s. Therefore, it is critical to correctly isolate, culture and identify skin stem cel s. As a reason, specific markers of epidermal stem cel s become a hotspot. Currently, a great progress in the biological markers of epidermal stem cel s has been made, but there is stil no absolute and proven marker for epidermal stem cel s. Most studies are focusing on integrin, keratin, P63, CD71, connexin 43, and telomerase. In addition, hoechst, CD90, CD98, CD200 have been reported recently. Each marker has its own shortcomings, and there are stil many problems that need to be solved.

BACKGROUND:Recently, the biodegradable materials with good biocompatibility and with no adverse reaction have been widely applied in the clinical treatment and care of gynecology and obstetrics. The development of the biodegradable material is very rapid. OBJECTIVE:To summarize the application of biodegradable materials in gynecology and obstetrics. METHODS: The first author searched PubMed and CNKI databases for articles related to biodegradable materials in gynecology and obstetrics using the keywords of “degraded materials, biodegradable materials, gynecological care, surgery” in Chinese and English respectively. This article has an outlook of the potential application in gynecology and obstetrics based on clinical experience. RESULTS AND CONCLUSION:Biodegradable materials with good biocompatibility and biological security play an important role in biomedical materials. Their polymers and degradation products show smal adverse reactions to the body, and have good biomechanical properties, physical and chemical properties and good workability, which have been widely used in gynecology and obstetrics, such as absorbable stylolite and tampon tape. Although we have made a great progress on the biomaterial research, it stil has the limitation and safety flaws in the clinic. As the biomaterial research is further developed, the biomaterial application prospect wil be more promising.

Olive oil is one of the important byproducts in agriculture. It is rich in oleuropein, which can be hydrolyzed into several bioactive phenolic compounds, including hydroxytyrosol (HT).There are many literatures have been confirmed that HT has significant pharmacological effects in the anti-inflammatory, anti-virus, regulation of metabolic disorders and treatment of degenerative diseases. However, HT has severe instability in vivo and in vitro. It is a challenge how to improve its stability through structural transformation or utilization of pharmaceutical means to processing. This paper will focus on biological activity of HT and its stability improvement, and provid some new ideas for expanding the research and promoting the development of HT in the field of Medicine.

Objective To clarify the intravenous thrombolysis utilization of acute ischemic stroke patients in Huashan hospital,and to analyze the factors affecting thrombolytic therapy compliance.Methods The data from a prospective cohort were analyzed.Consecutive acute stroke and transient ischemic attack patients from Huashan Hospital emergency room were recruited in 2014.Eligible ischemic stroke patients were divided into two groups according to intravenous thrombolysis or not.Results Totally 220 patients from emergency room were assessed in 2014.Among eligible patients,43 patients refused intravenous thrombolysis,whereas 59 patients chose this therapy.After multiple analysis,age,baseline NIHSS score,limb weakness,hemiplegic paralysis,facial paralysis or speech symptoms were significantly different between the two groups (U =936.000,P =0.024;U =284.500,P ＜ 0.01;x2 =8.824,P =0.003;x2 =7.732,P=0.005;x2 =5.169,P=0.038;x2 =5.040,P=0.025).Patients with NIHSS score ＜7 tended to refuse thrombolysis therapy in the receiver operating characteristic curve analysis (sensitivity 0.93,specificity 0.71).From 2008 to 2014,244 cases were analyzed in the thrombolysis database.Compared with patients with higher baseline NIHSS score,intracranial hemorrhage rate (2.6％ vs 19.4％;x2 =12.466,P ＜0.01),7-day mortality rate (1.3％ vs 16.9％;x2 =12.308,P ＜0.01) and 3-month mortality rate (3.8％ vs 21.1％;x2 =11.993,P ＜0.01) were lower in patients whose baseline NIHSS score ＜ 7 (minor group).A higher rate of excellent outcome (3-month modified Rankin Scale score ≤ 1)was observed in minor group (78.2％ vs 38.0％;x2 =34.403,P ＜ 0.01).Conclusions Intravenous thrombolysis was performed in 54.6％ of eligible ischemic stroke patients.Age,baseline NIHSS score,limb weakness,hemiplegic paralysis,facial paralysis or speech symptoms were associated with patients' decision of thrombolysis.The effectiveness and safety of intravenous thrombolysis were promising for patients with mild stroke.
