Chinese Journal of Medical Library and Information Science 2016;(2):43-46
The factors influencing the integration of MOOC and information literacy education in academic libraries were divided into objective factor, subjective factor and social factor according to their connotation and significance. Certain measures for their integration were proposed, such as strengthening network construction, perfecting literacy education systems, and carrying out systemic training.Integration of MOOC and information literacy education in academic libraries can improve information service, promote wide application of MOOC and information literacy ed-ucation in academic libraries.
2.Thyroid microsomal antigen-antibody system and its clinical significance
Chinese Journal of Immunology 1985;0(01):-
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.
3.CLINICAL SIGNIFICANCE OF TMAb AND TGAb MEASURED WITH ENZYME-LINKED IMMUNOSORBENT ASSAY
Chinese Journal of Endocrinology and Metabolism 1985;0(02):-
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.

Objective:Study the effect about cone beam CT(CBCT) image guidance sytem to improve the positioning accuracy and reducing the set-up uncertainty in precise radiotherapy. Methods:Use CBCT system to scan head and neck tumors patients (30 cases) and chest tumor patients (40 cases), including head and neck tumor patients were scaned 90 times, chest tumor patients were scaned 113 times. Setup deviation statistics about anterior and posterior, head and feet, left and right direction. Results:The patients with head and neck cancer, the maximum error of anterior-posterior is 6mm, Three directions errors which greater than 3mm all less than 10%. Patients with chest tumor position error are in the head and foot direction, greater than 5 mm up to 21.51%. Before and after the direction of the error did not exceed 5mm. The left and right direction greater than 5 mm up to 4.53%. Conclusion:It greatly enhances the precision of radiotherapy, improved the curative effect of radiotherapy by using CBCT online image guidance system for the patient position correction. Compared with EPID, patients scaned with CBCT absorb smaller cumulative dose, the image resolution is higher, image matching is more accurate. But compared with the ordinary helical CT,the resolution and scanning range also need to improve.

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.

Objective To explore the influence of family factors on physical activity behavior of central obesity patient.Methods A questionnaire investigation to 182 central obesity volunteers was carried out in a residential district of shanghai on April 2007.Results The percentage of the patients taking physical activities,at least one of whose family members participate in regular exercise,was 66.7%.It was significantly higher than that (43.6%) of other patients whose family members hardly ever participated in regular exercise any more(χ2=9.260,P=0.002).The percentage of patients taking physical activities,with highly family function,was 60.2%.It was significantly higher than that of the patients in moderately dysfunctional family (49.9%) and in severely dysfunctional family(35.5%)(χ2=6.448,P=0.04).The average APGAR score,Partnership score and Growth score of the patients in taking exercise group were 7.13±2.63,1.49±0.71 and 1.35±0.73. They were significantly higher than that of the patients in taking no exercise group (6.09±3.09,1.24±0.85 and 0.90±0.86) (t=2.095~3.845,P=0.000~0.038). While family size,family economic status and marital status showed no obvious effect on physical activity behavior of central obesity patients(χ2=0.027~1.709,P>0.05).Conclusion Highly family function and at least one of the other family members taking regular exercise can promote activity of central obesity patient in daily life.
