Objective To explore clinical nursing pathway(CNP) teaching method for nursing practice students.Methods Nursing practice students ( n =120 ) were randomly divided into two groups:experimental group and control group.CNP teaching method was applied in experimental group while traditional teaching method was used in control group.The test results of theory,operational skill,comprehensive quality,patient's satisfaction degree and nursing mistake between the two groups were compared.Results The results of theory,operational skill,comprehensive quality,patient's satisfaction degree in experimental group were obviously better than those in control group(P ＜0.05),the result of nursing mistake in experimental group was greatly decreased compared with that in control group(P ＜ 0.05).Conclusion CNP teaching method is superior to traditional teaching method and it greatly improve the teaching quality.

AIM:To observe the relation between astroglial activation state and ischemic tolerance in the gerbil hippocampus. METHOD: Bilateral occlusion of common carotid arteries and immunofluorescent methods in the gerbil hippocampal tissue. Slices were used. The morphological changes of the neurons were observed by light microscopy.RESULTS:Pretreatment with 2 minute bilateral carotid artery occlusion produced protective effects of CA 1 neurons. Glial fibrillary acidic protein (GFAP) staining showed weak positive cells in control group. Most of GFAP positive cells showed weak and middle positive cells after recirculation 1d and 2d following ischemic 3.5 min and preconditioning of the brain with sublethal ischemia respectively.CONCLUSION:Astroglial played an important role in cerebral ischemia. It is possible that state of astroglial activation related to neuronal survival in ischemic tolerance.

Objective To study the metabolic alteration in the brain of patients with cyanosed congenital heart disease (CCHD) by using 1H magnetic resonance spectroscopy ( 1H MRS) and discover the pathophysiology of chronic hypoxic brain, which will help to diagnose and treat this disease completely. Methods Twenty five patients with CCHD and 25 controls were performed PRESS 1H MRS and MRI, The areas under the resonance of metabolites were measured, the ratios of the other metabolites to Cr were calculated and compared. Results In patients with CCHD, the mean value of NAA/ Cr was significantly lower than that in controls ( P 0.05). Conclusion 1H MRS can detect brain metabolic changes in patients with cyanosed congenital heart disease in vivo noninvasively and can detect the metabolism disorder of the energy and amino acid, so the pathophysiology of this disease can be understood.

Objective To investigate the expression and clinical significance of thyroid transcription factor-1(TTF-1)and chromogranin A(CgA)in small cell lung cancer(SCLC). Methods The expressions of TTF-1 and CgA protein in 68 cases of SCLC tissues and 20 cases of normal lung tissues were examined by immunohistochemistry method,and their correlations with clinical features of SCLC were analyzed. Results The positive rates of TTF-1 and CgA protein in SCLC were 88. 2%(60 / 68)and 70. 6%(48 / 68),respec-tively,and they were higher than those in normal lung tissue[10. 0%(2 / 20)and 5. 0%(1 / 20);χ2 = 45. 442, P = 0. 000;χ2 = 26. 941,P = 0. 000]. The expression of TTF-1 protein was not related to the patients' age,sex and tumor size,while closely related to smoking index(χ2 = 4. 131,P = 0. 042),lymph node metastasis(χ2 =5. 488,P = 0. 019)and clinical stage(χ2 = 6. 011,P = 0. 014). The expression of CgA protein was not related to the patients' age,sex,tumor size and smoking index,while closely related to lymph node metastasis(χ2 =9. 895,P = 0. 002)and clinical stage(χ2 = 4. 145,P = 0. 042). Conclusion TTF-1 and CgA protein are highly expressed in SCLC,especially in the patients with lymph node metastasis and extensive disease.

Postgraduate administration is faced with new challenge in the affiliated clinical hospital because of the increasing quantity of postgraduates.The paper analyzed the characteristics of postgraduate administration and the status quo of information system construction in the affiliated clinical hospital and proposed the ideas of constructing information system for postgraduate administration from three aspects including system-frame,system-function and system-management.The purpose of the study was to provide reference for improving quality of postgraduate administration.

Improvement of the review of dissertation for doctoral degree is important for the training of qualified doctors.Current practice includes double-blind review and open review.This paper compares and analyses the outcome of the two kinds of reviews and found that double-blind review is more objective that the other(the mean of open review score is 96.39±2.069,the mean of double-blind review score is 85.18±6.635.P=0.001,P＜0.01).In the end some suggestions are proposed to improve the double-blind review system.

The paper analysed the double-blind review result of Ph.D candidates' dissertation at Peking University People's Hospital.Rigor deficiency and inadequate knowledge about the research subjects were identified as the main problems.In the end some suggestions were proposed from two aspects,namely,full-process management of Ph.D training and supervisor-team construction.

Objective To investigate the relationship between body fat distribution and pulse wave velocity (PWV) in middle-aged and aged population. Methods Two hundred patients received health examination were enrolled into the male group (103 cases) and the female group (97 cases). Visceral fat volume (VFV), subcutaneous fat volume (SFV) and ba-PWV were determined. Results Compared to patients in the female group, patients in the male group had significantly higher VFV values [(3.17 ± 0.84) kg vs (2.30 ± 0.94) kg], and lower SFV values [(15.56 ± 3.49) kg vs (17.69 ± 4.82) kg], In the male group, there existed a positive correlation between ba-PWV and age, VFV, fasting blood glucose,SBP and DBP. In the female group, a positive correlation was found between ba-PWV and age, SFV, TG, BUN, SBP and DBP, while a negative correlation was observed for HDL-C and Apo A1. Conclusion There was gender differences in body fat distribution in middle-aged and aged healthy population. In the male group , age, VFV, SBP, and DBP were the only independent and significant risk factors for ba-PWV. In the female group , age, SBP and Apo A1 were the independent risk factors for ba-PWV.

Objective To observe the effects of atorvastatin on the microglia activation after traumatic brain injury (TBI). Methods Sixty adult male C57/BL6 mice were randomly divided into sham group, atorvastatin group and saline group, 20 mice for each group. The atorvastatin group and saline group were given hydraulic combat to establish TBI mouse model. The shame group underwent the same surgical procedure without being exposed to percussion injury. The atorvastatin group was treated with atorvastatin (orally, 1 mg/kg)1 h after TBI and for 7 consecutive days. The saline group was given sa?line orally. The expression of microglia (Iba-1+) at the 1st, 3rd, and 7th day after TBI and matrix metalloproteinase-9 (MMP-9) around the lesion at the 3rd day after TBI were detected by immunohistochemical staining. Tumor necrosis factor (TNF)-αwas detected by Western blot assay at the 3rd day after TBI. Results The positive expression of Iba-1+microglia was signifi?cantly decreased in atorvastatin group than that of saline group at the 1st, 3rd, and 7th day after TBI (80.00±7.44 vs. 118.40± 6.65,85.60±10.87 vs. 189.00±7.51,69.40±5.54 vs. 102.40±10.89, P<0.05). The positive expression of MMP-9 was signifi?cantly decreased in atorvastatin group compared with that of saline group at the 3rd day after TBI (86.80 ± 8.40 vs. 133.80 ± 8.46, P<0.05). Results of Western blot assay showed that the positive expression of TNF-αwas significantly decreased in astorvastatin group than that of saline group at the 3rd day after TBI (0.64±0.01 vs. 0.97±0.02,P<0.05). Conclusion Ator?vastatin can reduce inflammation factor by influencing the microglia activation after TBI in mice.
