The studies on Internet public opinions in domestic library and information field from 2004 to 2013 were analyzed by subject analysis,which showed that studies on the hot spots of Internet public opinions using bibliometrics and knowledge map were rather mature while studies on how library and information science provides the theoretical support for Internet public opinions in its service were immature. The problems in studies on Internet public opinions in library and information field should be further studied, including their objectives, theoretical support, techniques and application.

5srRNA was isolated and purified from the reticulocytes of rabbit. It labeled with ~(125)I, then incubated with mouse myeloma cells (SP2/0). By autoradiography it was observed that ~(125)I-SsrRNA could pass into the nuclei of the cells. In a separate experiment, it showed that the incorporation rate of ~3H-TdR into nuclei of SP2/0 after incubation with 5srRNA was decreased as compared with that f control group, hence the result indicates that 5srRNA inhibits DNA synthesis of the SP2/0 cells and it seems to play a role in the regulation of gene expression through its hybridization with DNA sequences of the SP2/0 cells. Thus it is likely that 5srRNA might act as "erythroid denucleation factor".

OBJECTIVE: A series of recent studies have demonstrated the mechanism of migration and nerve net of neural stem cells. These theories have further substantiated neural stem cell transplantation. In view of these new findings, this paper reviewed the mode of migration and information of network. The significance of these theories was discussed.DATA SOURCE: We search on Pubmed with the key words "neural stem cell", "migration", and "nerve net", limiting the language to English and publication date from 1970 to 2004. At the same time we searched on CNKI.STUDY SELECTION: We selected the randomized and non-randomized controlled studies related to migration and nerve net building of neural stem cells. Review articles and articles with repetitive studies were excluded.DATA EXTRACTION: Among 39 papers selected, 16 papers concerning the development of this topic were selected, and the others were excluded.DATA SYNTHESIS: For retrograde lesions and severe injury of nervous system, transplantation of nerve stem cells may replace aging degenerative and dead nerve cells and rebuild neural network for the recovery of cerebral function. Migration of nerve cell and network principle can solve the survival, differentiation, migration and creation of nerve network after transplantation of nerve stem cells so as to realize the recovery and reconstruction of cerebral function.CONCLUSION: Neural stem cells can migrate to intended places and can build nerve net under some conditions, which will be useful for medicine deyelopment.

Medical team resource management is an effective way to control medical risk, ensure patient safety and enhance patient satisfaction. Based on defining the connotation, this paper illustrates the application and expe-rience of medical team resource management in Taiwan and finally proposes suggestions to apply medical team re-source management in domestic medical practice.

Objective To detect the expression of TRIM24 in uroepithelium cell carcinoma of bladder(BUCC)and analyze the relationship be?tween its expression and clinical pathological factors. Methods Immunohistochemical methods were employed to evaluate protein level of TRIM24 in BUCC. Results TRIM24 expression was observed in the nuclear compartments of tumor cells,while normal epithelia of bladder tissues exhibited negative results. For 72 BUCC tissues,TRIM24 overexpression(score≥4)was observed in 41.6%of cases(30/72). TRIM24 expression correlat?ed with invasive depth(P=0.029)and patients with high TRIM24 expression had high grade of BUCC(P=0.043). Conclusion There was sig?nificant over expression of TRIM24 in BUCC,which was correlated with poor differentiation and high grade of BUCC. It may become a candidate tar?get gene for the treatment of human uroepithelium cell carcinoma of bladder.

Image guided stereotactic body radiation therapy ( SBRT) has emerged as a promising technolo-gy for early-stage non-small cell lung cancer ( NSCLC) increasingly ,particularly for patients that are unable to tolerate or deny operation ,with a trend to replace surgical resection .Abundant clinical research results have dem-onstrated that SBRT is safe to yield local control rate of more than 90%without excessive toxicity in early -stage NSCLC.In this review ,we discuss the research progress on treating stage I NSCLC with SBRT .

Objective To observe the clinical efficacy of grain-sized moxibustion in treating cancer-related fatigue and improving the quality of life of patients with malignant tumor. Method Forty-six patients with malignant tumor were randomized into a grain-sized moxibustion group and a control group. The grain-sized moxibustion group received grain-sized moxibustion plus regular treatment, while the control group received the regular treatment only. The cancer-related fatigue intensity [Karnofsky Performance Status (KPS), European Organization for Research on Treatment of Cancer Core Quality-of-life Questionnaire (EORTC QLQ-C30), Piper Fatigue Scale (PFS)], white blood cell count, hemoglobin level, lymphocyte count, and neutrophil count were compared before and after treatment between the two groups. The correlation between cancer-related fatigue and the observed indexes was also analyzed. Result The grain-sized moxibustion group was better than the control group in mitigating the cancer-related fatigue, up-regulating hemoglobin level, and improving the symptoms (P<0.05). Conclusion Grain-sized moxibustion can effectively mitigate cancer-related fatigue via improving anemia condition and the symptoms of malignant tumor patients, and it can also enhance the quality of life of the patients.

Objective To investigate the relationship between air pollutant exposure and preterm delivery (PTD) by Logistic regression model, as the effect of air pollutant exposure to PTD made great concern today. Methods The present study consisted of 31 145 qualified birth cases, 80.09% of the total amount, from 1 Nov, 2005 to 1 Aug, 2007. The covariant items included maternal age, nation, education, residence, income, occupation, occupation exposure, parent-drinking, father-smoking, heating-type, folic acid supplement, season of pregnancy, prenatal health care, etc. The Logistic regression analysis was employed to control the confounding factors mentioned above, then the pollutant was introduced step by step to build the single, double and triple pollutant Logistic regression model to examine the association between three pollutants (SO2, NO2, and PM10) and PTD during the first and third trimesters of pregnancy. The air monitoring data (daily average of SO2, NO2, and PM10) were collected from Taiyuan Environmental Monitoring Station. Results In the first trimester, a quartile increase of NO2 exposure caused the risk for PTD increased by 22.7%. As for the effect of PM10, no significant differences were seen. In the third trimester, a quartile increase of NO2 exposure caused the risk for PTD increased by 19.1%. Conclusion The NO2 exposure during the pregnancy can increase the risk of PTD. The susceptible exposure-window choice is critical for the further study in this field.

Objective To assess the reliability and validity of the Chinese version of Multidimensional fatigue symptom inventory-short form(MFSI-SF).Methods The reliability and validity of the Chinese version MFSI-SF were assessed in a sample of 203 cancer patients.Statistical software was used to perform the analysis.Results The results showed moderate correlation between items and the total scale,the content validity index was 0.82,and exploratory factor analysis indicated five dimensions of the scale,the cumulative variance contribution was 56.65％.Confirmatory factor analysis showed moderate model fitting:x2/df=l.73,GFI=0.83,AGFI=0.79,NNFI=0.94,RMSEA=0.06,criterion validity was 0.585,and the Cronbach α of the total scale was 0.896.Conclusions The results demonstrated good convergent validity,it is suitable to evaluate fatigue status in Chinese cancer patients.
