Culturing sientific research ability and innovative ability of medical college students is important for the development of themselves and the medical colleges as well,which also meets the needs of the local economy and social development.This paper studies the undergraduate research projects in recent five years,to underst and tmedical students' research ability.Countermeasures are proposed to improve the situation.

Objective Newborn bilirubin encephalopathy seriously threatens the life and health of newborns, Both the mortality and morbidity are high.Cerebrospinal fluid bilirubin concentration can better reflect the blood-brain barrier function and brain bilirubin levels, which can help the diagnosis of bilirubin encephalopathy.Methods In order to meet the clinical needs, we confirmed the detection performance of the existing serum bilirubin detection system for cerebrospinal fluid bilirubin, including precision, accuracy and analysis of measurement range.Results The results showed that the detection system was linear at 1.0-25.1μmol/L, and the daytime CVat normal and pathological values was less than the precision requirement (6％) .The bias of each sample and the average bias are less than the allowable bias (5％) , the total error is less than the total allowable error (15％) .Conclusion Therefore, the performance of the detection system meet the industry standards, can be used for neonatal cerebrospinal fluid bilirubin detection.

Objective: To analyze the present situation of management of chronic diseases in the elderly of China, and discuss the corresponding countermeasures. Method: From the population structure, the diagnosis and treatment and fatality rate of chronic dis?ease, current problems of management of chronic diseases in community were studied. Results: The existing problems of manage?ment of chronic disease in community had chaos of management operation mode, low early detection rate of disease and the early man?agement etc. Conclusion: It is important to strengthen the government leading role, to mobilize initiative of community service organ?izations, to guide the understanding of chronic diseases in the elderly in order to achieve maximum health improvements.

Background: and Purpose Collateral circulation is considered an important factor affecting the risk of stroke, but the factors that affect collateral circulation remain unclear. This study was performed to identify the factors associated with collateral circulation, especially blood lipids. Methods: The study involved patients who had undergone digital subtraction angiography and were confirmed as having severe unilateral stenosis or occlusion of the internal carotid artery (ICA). We classified the collateral circulation status of each patient as good (Grade 3 or 4) or poor (Grade 0, 1, or 2) according to the grading system of the American Society of Interventional and Therapeutic Neuroradiology/American Society of Interventional Radiology. We collected data on patients’ characteristics and identified the factors that affect collateral circulation. Results: This study included 212 patients. The multivariate logistic regression analysis showed that the high-density lipoprotein cholesterol (HDL-C) concentration and a complete anterior half of the circle of Willis were independent protective factors for good collateral circulation, whereas elevated lipoprotein(a) [Lp(a)] and serum creatinine concentrations were independent risk factors for good collateral circulation. The area under the receiver operating characteristics curve (AUC) was 0.68 (95% confidence interval [CI], 0.61–0.76) for HDL-C and 0.69 (95% CI, 0.62–0.76) for Lp(a). A binary logistic regression model analysis of the joint factor of HDL-C and Lp(a) yielded an AUC of 0.77 (95% CI, 0.71–0.84). Conclusions In patients with severe unilateral ICA stenosis or occlusion, the combination of HDL-C and Lp(a) is a useful predictor of collateral circulation.

Type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD) are the most problematic metabolic diseases in the world. NAFLD encompasses a spectrum of severity, ranging from simple steatosis to non-alcoholic steatohepatitis (NASH) and fibrosis, increasing the risk of cirrhosis and hepatocellular carcinoma. Importantly, NAFLD is closely linked to obesity and tightly interrelated with insulin resistance and T2DM. T2DM and NAFLD (T2DM-NAFLD) are called as the Xike Rixijing Disease and Tonglaga Indigestion Disease respectively, in Mongolian medicine. Xike Rixijing Disease maybe develop into Tonglaga Indigestion Disease. Forturnately many Mongolian medicines show efficient treatment of T2DM-NAFLD, such as Agriophyllum squarrosum, Haliyasu (dried powder of camel placenta), Digeda-4 (herbs of Lomatogonium carinthiacum, rhizomata of Coptis chinensis, ripe fruits of Gardenia jasminoides, herbs of Dianthus superbus), Guangmingyan Siwei Decoction Powder (Halite, ripe fruits of Terminalia chebula, rhizomata of Zingiber officinale, fruit clusters of Piper longum), Tonglaga-5 (ripe fruits of Punica granatum, barks of Cinnamomum cassia, ripe fruits of Amomum kravanh, fruit clusters of Piper longum, flowers of Carthamus tinctorius), Tegexidegeqi (rhizomata of Inula helenium, ripe fruits of Gardenia jasminoides, rhizomata of Platycodon grandiflorum, rhizomata of Coptis chinensis, heartwood of Caesalpinia sappan), Ligan Shiliu Bawei San (ripe fruits of Punica granatum, barks of Cinnamomum cassia, ripe fruits of Amomum kravanh, fruit clusters of Piper longum, flowers of Carthamus tinctorius, ripe fruits of Amomum tsao-ko, rhizomata of Zingiber officinale), etc. Principles of Mongolian medicine in treating diseases: by balancing “three essences or roots” and “seven elements”, strengthening liver and kidney function, transporting nutrients to enhance physical strength and disease resistance, and combined with drugs for comprehensive conditioning treatment. However, their molecular mechanisms remain unclear. In this review, we prospect that Mongolian medicines might be a promising treatment for T2DM-NAFLD by activating P2X7R/NLRP3/NF-κB inflammatory pathway via lipid-sensitive nuclear receptors (i.e., FXR and LXR).
