Renal interstitial fibrosis is basically the common terminal pathway of various progressive renal diseases. Decrease of interstitial capillary density plays an important role in renal interstitial fibrosis. Endothelial progenitor cells can be induced to differentiate into mature vascular endothelial cells. They contribute to angiogenesis and angiopoiesis, and therefore may be a potential therapeutic approach for chronic kidney disease..

Described in this paper are the design of location navigation system for journals and its functions implementation in small and medium-sized library with limited funds, technologies and staff.

Objective To investigate the relationship between of the serum homocysteine (Hcy) level and the occurrence and severity of diseased coronary arteries in patients. Methods The total serum Hcy content was determined in sixty-seven patients with diseased coronary arteries and forty-three normal subjects. They were all subjected to coronary artery angiography for evaluation. Using the Gensini's scoring system the degree of severity of of pathology the coronary arteries were assessed. Other risk factors were analyzed in addition to Hcy and Gemini's scores. Results The total serum level of Hcy in patients with diseased coronary artery was significantly higher compared with the normal controls (P

The reform in cultivating professional-degree programs in Clinical Medicine Education contributes to the transformation of training mode, which surpasses the connotative bounds of the inherent education management. The personalized training of students has made it more challenging for both the tutor and the faculty to involve in education management, the effectiveness of which is highly valued due to the pressing need for sound medical ethics. Furthermore, the development of information technology calls for the reform of education management as well as the emphasis of student-centered approach. This article summa-rizes the existing problems of current education management mode for master degree programs of profes-sional clinical medical education. In addition, a three-level management system composed of medical experts is brewed and put forth. This system, based on compensation and restraint, assessment and incentive, ser-vice as well as security, is meant to facilitate the training of application-oriented medical talents.

Objective To discuss the efficacy of applying management-by-objectives(MBO) in the hospital-level nursing quality control group.Methods Goals of objective management and assessment details were set by leaders of quality control groups along with the nursing department at the beginning of the year.The nine subordinate groups performed upon the required criteria,completed the quality inspection on time and recorded group activities.At the end of the year,group leaders reported to the hospital-level nursing quality committee and head nurses about their performances,where several major honors were rewarded to the best performing groups.SPSS 17.0 software was used for data statistics.The measurement data were analyzed by paired t test data while enumeration data by chi-square test.Results Scores of assessment items were significantly raised after implementing MBO(P＜0.05).Scores of key items,such as high quality care,emergency management,nursing skill,were increased to (98.1 ± 2.2),(97.7 ±2.7),(99.6±0.6),(96.1 ±2.1)from (93.6 ±2.5)(P=0.009),(93.0 ± 2.6) (P=0.009),(96.2 ± 1.3) (P=0.000) and (89.3 ± 4.5) (P--0.000),respectively.Care complaints were sharply dropped for all inpatient wards while numbers of management innovationand process reengineering were greatly increased (x2=8.884,P=0.031).Condusion Introduction of MBO in the hospital-level nursing quality control group does facilitate the continuous improvement of care quality.

Objective In order to know the proper prevention and nursing measures for postoperative hemorrhage among patients with tyroid surgery. Methods Analized the medical history of 19 patients with postoperative hemorrhage after thyroid surgery retrospectively. Results The 19 patients with postoperative hemorrhage were all recovery smoothly by careful nursing and proper treatment. Conclusions Uncomplete intraoperative hemostasis, intraoperative breathholding and improper placement of drainage structures are the risk factors for postoperative hemorrhage. Careful postoperative observation and nursing can avoid certain postoperative hemorrhage.

Objective To observe the impact of different culture conditions on the growth of the endothelial progenitor cells(EPCs) from rat peripheral blood. Methods Mononuclear cells obtained from rat peripheral blood were isolated by using density gradient centrifugation. According to the culture medium added with vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and the dishes were precoated with fibronectin or not, the mononuclear cells were divided into different groups and cultured under different conditions in vitro to compare the differences of the growth conditions. The different growth conditions were recorded and the result was calculated by statistics software. At last, the cells were identified by immunohistochemistry and immunofluorescence. Results The mononuclear cells from rat peripheral blood grew in the manner of keeping close to the wall in vitro. The cells and cell colonies cultured for 7 days hinted:under the same culture conditions, precoating FN was beneficial to the adherent proliferation of EPCs (t=4.43, P＜0.05; t=3.70, P＜0.05). Excluding the impact of fibronectin, growth factors could promote mononuclear cells differentiation to EPCs, indicating that growth factors enhanced proliferation of EPCs (t =-13.22, P＜0.01; t =-10.96, P＜0.01). Immunohistochemistry and immunofluorescence showed that, at day 4, 7, 10 of cells cultured, CD34 and CD133 expressions were increased gradually [(35.7±4.2)%, (60.1±3.8)%, (81.8±6.4)%; (3.2±0.9)%, (18.4±7.3)%,(32±3.8)%, respectively]; at day 14, both were decreased [(32.1±5.4)%, (1.9±2.7)%]; but Flk-1was increased at day 4, 7,10, 14 [(31.2±3.5)%, (40.6±5.3)%, (71.2±8.4)%, (81.5±4.1)%].Conclusions Fibronectin is conducive to adhesion and proliferation of EPCs. VEGF and bFGF play an important role in the differentiation of EPCs. The success culture of EPCs in vitro will provide a sufficient number of seed cells for its application in vascular tissue engineering, and offer new ideas for peripheral blood stem cell transplantation for the treatment of various diseases.

SHRs were randomly divided into three groups: SHRs control group, Benazepril group (10mg/kg?d) and Losartan group (30mg/kg?d). WKYrats act as the normal control group. The animals were treated for 3 months. Compared with WKY rats, the blood pressure, angiotensinⅡ(AⅡ)levels in blood and myocardium, mitogen activated protein kinase (MAPK) activity, and myocardial hypertrophy in SHRs control group were increased ( P

To investigate the changes in nitric oxide (NO) and angiotensin (AⅡ) in rat with spontaneous hypertension (SHR) and the effect of benazepril on production of NO/AⅡ. The animals were divided into three groups: normotensive (WKY) group, SHR control group and benazepril group. Blood pressure was measured by the tail-cuff method. NO - 3 concentration in serum was assayed by activated cadmium reduction method; cGMP and AⅡ levels in vascular tissue were assayed by RIA (radioimmunoassay). The results showed that blood NO - 3 concentration and vascular cGMP level were all lower in SHR group compared with WKY rats(P

Objective To evaluate the serum Level of B-natriure peptide(BNP)in elderly patients with Left Ventricular dysfunction and to determine the correlation between the BNPand hemodynamic Variable.Methods According to New York Heart Association(NYHA)class.51 patients with Left Ventricular dysfunction and 28 without Left Ventricular dysfunction(control group)were measured.BNP Levels were obtained,Left ventricular ejection fraction(LVEF)was assessed by echocardiography,center vein pressure(CVP)was determined in NYHA Class Ⅲ-Ⅳ groups.Results BNP were (39.32?5.51)ng/L in control group,respectively(265.94?63.13)ng/L in NYHA ClassⅡgroup(n=18),(569.93?109.17)ng/L 、CVP was(9.67?1.23)cmH_2O in NYHA class Ⅲ group,(2 764.33?1 020.53)、CVP was(19.61?4.57)cmH_2O in NYHA class Ⅳ.The difference of BNP and CVP in groups were scegnificant(all P
