1.Functions and characteristics of scientific research administration in modern hospitals
Chinese Journal of Medical Science Research Management 2010;23(4):220-224
Along with the globalization of science and technology, the investment on medical research has been increased gradually in recent years, which brings many challenges to the administration of scientific research. The traditional passive conception and model of research administration can no longer meet the needs of modern research development, and therefore changes are urgently needed. The function of research administration in modern medical research needs to be redefined and new characteristics will subsequently arise. The changes are believed helpful in promoting the efficiency of research funding and implementation of the research projects and further facilitating the transformation and application of research achievements.
2.Bi-modality image classification based on independent component analysis.
Journal of Biomedical Engineering 2014;31(5):1031-1036
We in the present research proposed a classification method that applied infomax independent component analysis (ICA) to respectively extract single modality features of structural magnetic resonance imaging (sMRI) and positron emission tomography (PET). And then we combined these two features by using a method of weight combination. We found that the present method was able to improve the accurate diagnosis of Alzheimer's disease (AD) and mild cognitive impairment (MCI). Compared AD to healthy controls (HC): the study achieved a classification accuracy of 93.75%, with a sensitivity of 100% and a specificity of 87.64%. Compared MCI to HC: classification accuracy was 89.35%, with a sensitivity of 81.85% and a specificity of 99.36%. The experimental results showed that the bi-modality method performed better than the individual modality in comparison to classification accuracy.

5.Recent progress of study in pregnancy and thyroid cancer
Chinese Journal of Endocrinology and Metabolism 2014;30(12):1132-1134
Thyroid cancer accounts for the most common endocrine malignancies in women during childbearing age.Many questions remain to be answered regarding the association between thyroid cancer and pregnancy.This review will discuss both the effects of pregnancy on thyroid cancer and vice versa.Recommendations on how to manage thyroid cancer in pregnancy will also be cited from a Chinese academic guideline as listed at the end of this review.
6.Reoperation of postoperative recurrent hepatocellular carcinomia
Chinese Journal of General Surgery 1993;0(02):-
Objective To evaluate the curative effect of reoperation on postoperative recurrent hepatocellular carcinoma (HCC). Method From Jan.1995 to Dec. 1998, 18 recurrent HCC patients underwent 27 sessions of reoperation in our hospital. Result The mean interval between first and second operation among 18 patients was 39?14 months, and for the 9 cases, in which cancer recurred after second surgery, the mean interval between the second and the third operations was 21?4.5 months (P

By using ATP-ase histochemical and OKT6 colloidal goldsilver immunohi- stochemical methods, we have studied the location and distribution of Langer- han's cells (LCs) in human esophageal epithelium. The results of our study showed that the dendritic LCs scatter in the basal and middle layers of the esophageal epithelium. The morphology and density of LCs are variable as the age grows and the location changes, more LCs are found in the adult esophageal epithelium than in the foetus, and more LCs are found in the lower segment of esophagus than in the upper segment.
8.Translational medical science:the medical science beneficial to patients
Basic & Clinical Medicine 2006;0(08):-
With the rapid development of life sciences, translational medical sciences have a new significance recent years. Translational medical science aims to eliminate the barriers between clinical, pharmaceutical drug breakthroughs and basic research, to shorten the distance from bench to bed side, and to facilitate rapid patient benefits from medical sciences. Translational medical science concurrently agrees with modern 21st century research trends, as well as emphasizing upon Chinese goals of health and sanitation (hygiene science), preventing and treating disease to preserve and improve health standards and quality of life. Following a long-term self study model of integrating basic with clinic research since 1921, Peking Union Medical College Hospital in collaboration with a variety of basic medical science institutions recently and initiated a pilot project of translational medical science in China.

Objective To discuss the therapeutic effect of uterine arterial embolization in treating adenomyosis.Methods Uterine arterial embolization was performed in 80 patients with adenomyosis.The patients were followed up for 3,6,12 and 24 months after the operation.After the treatment the degree of dysmenorrhea,the menstrual flow and the uterine volume were observed and were compared with those before the treatment.Results After uterine arterial embolization the clinical symptoms were relieved in all 80 patients.The menstrual flow was markedly decreased,the anemia was obviously improved and the uterine volume was significantly reduced,while the ovary functioning was not apparently affected.The symptom of dysmenorrhea completely disappeared one month after the therapy in 76 cases and four months after the therapy in the remaining 4 cases.Conclusion Uterine arterial embolization is a mini-invasive and safe therapy with remarkable therapeutic results and few side-effects.Therefore,this treatment can significantly improve the patient's living quality.
