[Analysis of projects funded by NSFC in field of efficacy material base of traditional Chinese medicine].

This paper introduces the application and financing of programs of efficacy material base of traditional Chinese medicine funded by the National Natural Science Foundation of China(NSFC), the Youth Science Fund and the Regional Science Fund from 2016 to 2019, and conducts analysis and summary in terms of research objects and analysis methods, with the aim to provide reference for applicants for programs of efficacy material base of traditional Chinese medicine.

[Analysis on projects of ethnomedicine and ethnopharmacology funded by National Natural Science Foundation of China from 1986-2018].

Through summarizing the applications and funding for research related to ethnomedicine and ethnopharmacology in the department of Health Sciences of the National Natural Science Foundation of China( NSFC) from 1986 to 2018,and analyzing the categories,numbers,funds and research contents of all funded projects including Mongolian,Uygur,Tibetan,Zhuang,Miao,the study is aimed to provide certain reference for the declaration of ethnic medicine project. The results showed that the national medicine project application numbers and the amount of funding growth after 2011 have increased significantly,but the overall level of research remained to be further promoted,and the lack of suitable for the study of ethnic medicine features and ways,has yet to mainland medical universities and research institutions to give more attention and jointly promote the development of basic research in the field of ethnic medicine.

[Overview of research projects funding in traditional Chinese medicine oncology field supported by National Natural Science Foundation of China].

In this paper, the funding situation of traditional Chinese medicine oncology research projects supported by National Natural Science Fund from 1986-2016 was reviewed. The characteristics of funded projects were summarized from funding amount, funding expenses, funding category, and the main research contents of projects, etc. At the same time, the main problems in the projects were analyzed in this paper, in order to provide reference for the relevant fund applicants.

[Analysis of projects funded by NSFC in field of Chinese material medica resource in recent three years].

The paper reviewed the sponsorship and final reports of projects focus on Science of Chinese materia medica resource in Medical Science Department, National Natural Science Foundation of China. The applicant and supportive organizations were analyzed. The progress and results of some projects were summarized by research fields including formation mechanism of Dao-di herbs, research of plant taxonomy, breeding and cultivation of medical plants, ecological and environmental adaptability of Chinese materia medica resource, quality assessment of Chinese materia medica resource, and biosynthesis and regulation of active compounds. In addition, the potential problems and the most and least focused areas in the application were summarized for reference.

[Analysis of different mutations in regulatory sequence of prolactin gene during the formation of 17 beta-estradiol-induced prolactinoma in eutopic and ectopic pituitary of rats].

OBJECTIVE: To analyze different mutations in regulatory sequence of prolactin (PRL) gene during the formation of 17 beta-estradiol (E2 ) -induced prolactinoma in eutopic and ectopic pituitary of rats. METHODS: Male Sprague-Dawley rats transplanted with an isologaus pituitary under renal capsule were treated with subcutaneous implantation of an empty or E2-laden silastic capsule. Reverse transcription-polymerase chain reaction was employed to evaluate the expression of PRL mRNA in pituitary glands, and DNA sequencing was used to analyze the mutation in regulatory sequence of PRL gene. RESULTS: After treated with E2 for 120 days, both the eutopic and ectopic pituitaries were three times more heavier than those from control group (P < 0. 01) , and the body weight of rats was decreased to 42. 90% of the control group (P < 0 01 ). The PRL mRNA expressions in glands from the eutopic and ectopic pituitaries 120 days after treated with E2 were much more than those in untreated pituitary glands (P <0. 01). DNA sequencing showed seven mutations in the regulatory sequence of PRL gene in the eutopic pituitaries 120 days after treated with E2 , while the mutation in the ectopic pituitaries was decreased. CONCLUSIONS: Prolactinomas can be induced by chronic treatment with E2 in both the eutopic and the ectopic pituitaries transplanted under renal capsule distant from the hypothalamus. Different mechanisms exist in the formation of eutopic and ectopic prolactinomas.
