1.Thinking about improving the cross-cultural communication capacity of the teaching foreign language on Chinese medicine
Chinese Journal of Medical Education Research 2011;10(9):1047-1049
The purpose of foreign language teaching in Chinese medicine is not only translation,but also clearly the role and the purposes of translation.Inputing a culture to another culture is not culture exchange,but cultural coagulation.Expressions with modem scientific system allow speculative natural philosophy freed from the ancient Chinese-style paper into the theory expressed by modem scientific language in order to solve the problems of teaching foreign languages of traditional Chinese medicine texts.
2.Function of fetal microchimerism during disease and tissue repair in parous women
Chinese Journal of Tissue Engineering Research 2012;16(6):1133-1136
BACKGROUND: Fetal microchimerism is a kind of stem cells which comes from fetus in pluripara. The research on fetal microchimerism is a hotspot because it may affect the health condition of pluripara.OBJECTIVE: To introduce the methods of how to detect fetal microchimerism, and the function of fetal microchimerism during disease and tissue repair of the mother.METHODS: Fetal microchimerism was used as a key word, and papers published before 2011-05-20 were retrieved in PubMed. Repetitive papers were eliminated.RESULTS AND CONCLUSION: Totally 655 papers were retrieved, and finally 26 were reviewed. There are several methods used for fetal microchimerism detecting, and fetal microchimerism may pay an important role in the pathomechanism of pluripara autoimmune diseases, cancer and tissue repair.
3.Improvement of mouse spermatogonial cells transplantation method
Acta Anatomica Sinica 2010;41(1):165-168
Objective To improve the current method of spermatogonial cells transplantation, and make the new method become more operative and easy to carry out. Methods The spermatogonial cells in rC57BL6/tg14 (act-EGFO-Osb Y01) mice that expresse GFP protein were collected as the donor cells, and by using a modified syringe, and then were injected into the seminiferous tubules of pretreated wild type GFP-null mice through testicular efferent duct. The transplantation outcome was evaluated by trypan blue stainting and fluorescent microscopic examination and pathohistological analysis of transplanted testis. Results The transplanted testis of recipient mice showed green fluorescence signal, and the signal of seminiferous tubules was found significantly higher than that of the surrounding tissues. The transplanted GFP-positive cells generated colonies and spermatogenesis but pretreated wild type GFP-null mice were not found. Conclusion The expressed GFP protein spermatogonial cells in rC57BL6/tg14 mice were successfully transplanted in the wild type GFP-null recipient mice, fourthermore the improved transplantation method simplified the triditional one and achieved the same transplantation results.
5.Screening of the diagnostic and thermostable urate oxidase-producing strain and optimization of the fermentation conditions
Chinese Journal of Biochemical Pharmaceutics 2016;36(9):154-157
Objective To screen a thermostable urate oxidase-producing strain, optimize the fermentation conditions and study the enzymatic properties.Methods A urate oxidase-producing strain was screened from high temperature starter based on transparent circle method.Its 16S rDNA sequence was then amplified and analyzed.Meanwhile, the phylogenetic trees were built.Optimization of the fermentation conditions from this strain was carried out.The enzymatic properties of urate oxidase were studied.Results A urate oxidase-producing strain, named Bacillus subtilis ZX-6 by molecular identification, was obtained.The production of urate oxidase under the optimized conditons (135.9 U/L) was 133.7%higher than before.The optimum reaction temperature and pH were 45℃ and 7.6 respectively.The residual activity of urate oxidase at 37℃ for 48 h was still 17.2%.Conclusion The successful screening of a thermostable urate oxidase-producing strain and optimization of the fermentation conditions will lay a foundation for the further research.
6.Meta analysis of BISAP score system in predicting the severity of acute pancreatitis
Chinese Journal of Pancreatology 2014;14(3):149-153
Objective To investigate the value of BISAP scoring system in predicting the severity of acute pancreatitis.Methods Medline,EMBASE,Science Direct,Springer link,CBM,Cnki,Wan fang and VIP database were retrieved by computer between January 2000 and March 2013,and articles of BISAP score system in predicting the acute pancreatitis were collected according to strict inclusion criteria.Quality assessment was made by QUADAS scale.Meta-Disc1.4 software was used to analyze the heterogeneity of included articles and perform quantitative synthesis,as well as calculate the pooled sensitivity and specificity,positive likelihood ratio,negative likelihood ratio,and draw the ROC curve,and the results were presented with 95% CI.Results A total of 11 articles were included,and there were 7 Chinese articles and 4 English articles.According to QUADAS scale,there were 4 articles of A grade,5 articles of B grade,2 articles of C grade.There were 6 studies using 2 as BISAP cut-off value,and 9 articles using 3 as cut-off value,while 4 studies using 2 cut-off values.Pooled analysis showed diagnostic odds ratio of 8.03 (95 % CI 5.66-11.38) when cut-off value was 2,and diagnostic odds ratio of 7.49 (95% CI 5.35-10.49) when cut-off value was 3.There were moderate heterogeneity in both groups (I2 =63.3 %,P =0.018; I2 =56.1%,P =0.019).When BISAP cut-off value was 2,the pooled analysis of sensitivity,specificity,positive likelihood ratio,negative likelihood ratio and area under curve (AUC) were 59% (95% CI56%-63%),82% (95% CI 80%-83%),3.50 (95% CI2.96-4.14),0.45 (95% CI0.36-0.56) and0.82; and when BISAP cut-off value was 3,the corresponding values were 44% (95% CI41%-47%),90% (95% CI 89%-91%),4.59 (95% CI 3.31-6.37),0.64 (95% CI 0.61-0.68) and 0.64.The former had a high sensitivity,low specificity and large AUC,while the latter had a low sensitivity,high specificity and small AUC.Conclusions The best cut-off value of BISAP in predicting SAP is 2.When cut-off value is 2,the misdiagnosis rate is low,and the false positive rate is in the acceptable range,which is suitable for clinical application.
