Objective To describe the academic impact of publications from National Institute of Parasitic Diseases （NIPD），Chinese Center for Disease Control and Prevention，so as to give the quantity evidence for scientific research decision making. Methods The SCIE papers of NIPD published from 2011-2015 were searched and statistically analyzed. The number of published papers，citation frequencies，h⁃index，and funding resources were analyzed. The academic impact of the institute was assessed according to these data. Result A total of 361 papers were published by NIPD，and the quantity increased year by year. The majority type is original articles. The total citations were 1 641 times，the average citation per paper was 5.19 and h⁃index was 17. The majority of these papers were published in foreign professional periodicals，whose impact factors were between 1.194 and 6.751. The major resources of NIPD were from China，and NIPD also had good collaborations with institutions in US and Switzerland. In China and Asia，NIPD led the research in the field of parasitology and tropical medicine. Conclusion The quantity and quality of annual published papers of NIPD are on the rise. However，NIPD lagged behind the leading institutions in the world.

The paper briefly introduces the definition, characteristics of MOOC and its development both in China and abroad, ana-lyzes the relation between medical college and university library and MOOC.It points out that libraries should provide embedded course services based on MOOC, establish MOOC Information Commons ( IC) , develop MOOC specialized database and enhance capability of the librarians in order to develop MOOC from various aspects and continuously promote information service innovation.

Objective:For improving the imperfection of the Active contour model.Methods:This paper puts forward a new active contour model based on the greedy algorithm.The average contour length term is added into the internal energy of the model.The gradient directional energy is introduced to the external energy of the model.A fast algorithm is introduced to solve the minimum of region energy.The algorithm of add or delete snaxel also adopted in this paper.Segmentation of the MRI brain tumor are studied in the experiments.Results:Comparing to the manual segmentation and the GVF segmentation,the method is better.Conclusion:The results of experiments indicate that the model is none sensitive to initial contour.So this algorithm is practical.

OBJECTIVE To know the incidence, etiology, risk factors of hospital-acquired pneumonia(HAP). METHODS From Jan 2003 to Dec 2004, 129 cases of HAP were retrospectively studied. Epidemiologic data, etiology , and evolution of pneumonia were recorded. RESULTS The 115 patients with HAP had one or more intrinsic risk factors, mainly malnutrition (albumin values

Hypoglycemia is a common and early metabolic disease of neonate.Serious and persistent hypoglycemia could result in brain damage.So far the pathogenesis of the disease is on research,but the definition of hypoglycemia,the glucose threshold of intervention,and diagnostic criteria of brain damage are still unclear.The pathogenesis of hypoglycemia is complicated.Brain damage may be related to the specific excitory amino acids receptors,reduced blood flow in occipital lobe,and cerebral hypoxia and ischemia.Diffusion weighted imaging of brain MRI and magnetic resonance spectroscopy are strongly recommended for the diagnosis of brain damage.Besides,clinical manifestation and cerebral function monitor are also included in the diagnosis.The threshold of intervention is suggested as serum glucose concentration with 2.2 ～ 2.6 mmol/L.

A probe into the management of outpatient medical records written by rural doctors:Such a record is indispensible for technical appraisal of medical accidents; yet writing of such a record might involve illegal medical practice or go beyond the scope of practice.It is recommended to normalize the behavior of rural doctors in their writing of outpatient medical records,stipulating that the Basic Regulations on Medical Records do not apply to rural doctors at present.It is also recommended that separate regulations for rural doctors be formulated,along with a promotional period before these regulations are in practice.An alternative would be clarifying that Article 28 of the Regulations of Medical Malpractice Settlement do not apply to rural doctors.
