Of these institutions, library plays a major role in metaliteracy education since it is not only the main driving force of metaliteracy education and the institution to make,file and maintain the resources for metaliteracy education, but also is the organizer, coordinator and manager of metaliteracy teachers.

This paper reports serum ?_2 microglobiln (?_2M in abbreviation) in 216 normal children of different ages. Urin ?_2M in 60 normal adults; and both in 50 cases of common glomerular disease in children were detected by RIA. The results showed that serum ?_2M is more accurate than BUN in judging the renal function. The elecating serum ?_2M is coincidence with the elevating of diastolic pressure of the sick children. The dynamic observation on delayed cases examination of serum ?_2M and urin ?_2M may be of help in monitoring the pathological changes in glomerular and tubule.

Positron emission tomography-computed tomography (PET-CT) is widely used in the diagnosis and grading of FDG-uptake lymphoma,particularly in the extranodal lesions.Baseline PET-CT improves the accuracy of subsequent response assessment.Focal FDG uptake within the bone or bone marrow is highly sensitive for involvement in Hodgkin' s lymphoma (HL) and diffuse large B-cell lymphoma (DLBCL) and is better than bone marrow biopsy.Many international trials suggest that interim scan is prognostic,but not proven as a method to guide therapy.A negative PET-CT scan at the end of therapy is the best predictor of a good outcome.However,surveillance PET-CT scan should not be done routinely.

Objective To study whether the positive psychological capital intervention could improve the level of psychological capital and the will of retention of clinical nurses. Methods A randomized controlled trials was conducted. The control group did not take any psychological intervention;Intervention group was given psychological capital intervention, which was conducted for 7 weeks (once a week, 1-2 hours per time).It used Nurses′ Psychological Capital Questionnaire and Nurses′ Retention Intention Questionnaire to evaluate the participants before and after intervention. Results There were no statistical differences between intervention group and control group in the score of Nurses′Psychological Capital Questionnaire (84.74 ± 10.04 vs. 86.16 ± 8.57,P > 0.05 ) and Nurses′ Retention Intention Questionnaire ( 19.21±3.47 vs. 18.54±3.41,P>0.05 ) on the day before intervention. The score of Nurses′Psychological Capital Questionnaire of intervention group was 93.89 ± 7.10 on the intervention day and 93.60 ± 6.88 three months later while the control group scored 84.41 ± 6.58 and 83.92 ± 9.31.The intervention group was statistically lower than the control group (t=6.156, 5.155, P<0.05) .And the score of Nurses Retention Intention Questionnaire was 22.42±2.66 on the intervention day and 22.24±2.61 three months later while the control group scored 18.61 ± 3.08 and 19.21 ± 3.47. The intervention group was statistically lower than the control group (t=5.866, 4.292, P<0.05). Conclusions Positive psychological capital intervention can improve the the will of retention of clinical nurses.

Objective:To observe the relationship between the vascular endothelial growth factor (VEGF) and the survival of flap in the rat back which received radiotherapy. Methods: Forty Wistar rats were divided into four groups. A 3×4 cm~2 full thickness dorsal flap with pedicle was prepared at the posterior end. The skin flaps were given~(60)Co radiotherapy in the 2, 4, 6 day postoperation. Group A was given of VEGF in the third, fifth, seventh day. Group B was given a high quantity of VEGF. Group C was the control of Group A,Group D was the control of Group B. Control groups received normal saline. Results: Pathological observation revealed that the survival of flap and blood vessel lumen diameter of group A were higher than that of group B(P<0.05). Group A showed remarkable difference compared with group C(P<0.01). Group B showed remarkable difference compared with group D(P<0.05). Results of fluorescence staining and SDH examination showed that three times injection had better results than one time injection. Conclusion: Three times injection of VEGF has better effect on the viability of rat skin flap than one time injection.

Objective To know the quality of life-related factors in patients with asthma, and then carry out certain effective counter nursing measures. Methods Investigated 137 patients with severe asthma, to know their nursing requirement and factors which can influence their quality of life, and then counert nursing measures were carried out for patients according to the results of investigation. Compared the quality of life of patients with asthma before and after the research. Results There was a negative correlation between the quality of life for patients with asthma and their smoking habit, sleeping station, disease course and complica-tions respectively, while a positive correlation between the quality of life for patients with asthma and their edu-caiton background, asthma-related knowledge and incomes. The nursing requirement about health education, psychological interview, treatment services were the main requirements. After the nursing intervention, the quali-ty of life for patients with asthma was significant better than before. Conchlsions There were several factors which can influence the quality of life for patients with asthma, analysis,carry out certain strategy and eval-uation a kind of proper mode for adult patients with asthma.

Objective To investigate the intervention effect of integrated care including exercise therapy,example learning and psychological support to ease the hematopoietic stem cell transplantation (HSCT) related complications.Methods 40 cases were divided into the intervention group and the control group according to their hospital number,there were 20 cases in each group.The intervention group received integrated care and control group adopted traditional methods.HSCT symptoms scale was used to evaluate the intervention effects in 6 time points (the day before pretreatment,the day before HSCT,the 7th day,14th day,21th day and three months after HSCT).Results There were no statistical differences between the two groups in the score of HSCT scales on the day before pretreatment.The intervention group was statistically lower than the control group in the score of HSCT scales on the day before HSCT,the 7th day,14th day,21th day and three months after HSCT,P＜0.05.Conclusion The integrated care can reduce HSCT complications and worthybe popularizing.

Aim To test the strength of Kraekow bilateral locking stitchfor tendon or ligament free end fixation and evaluate the stitch which wasused in reconstruction of cruciate ligament or secure fixation of soft tissue tobone. Methods Twenty-four specimens of patellar tendon free end, whichwere divided into 3 groups according 2 or 3 stitches and 6 subgroups ac-cording No1 Ethilon or 0.4 mm diameter stainless steel wire different suturematerials, fixed with Krackow locking stitch, were undertaken the tensiletest respectively, so as to find out the least stitches and efficient suture pat-tern. Results 2 Krackow locking stitches had more strength than that of0.4 mm diameter stainless steel wire, the fixation strength of 2 stitcheswhich used No1 Ethilon was more than 80 N, superior to the failure strengthof material itself, it still maintained the same strength if the first stitch wasacross the tendon tissuetransversely. There was no significant differencebetween 2 and 3 Krackow locking stitches in suture strength statistically, thefixation strength was superior to the suture material, it could reduce the'suture exposure when the first stitch is across the tendon tissue while main-tains a comparable strength to other suture. Conclusion If attempt to makea higher strength of suture, we should focus on selecting a stronger materialsor adding the suture materials in number rather than the stitch number.

Objective To study the effects of erythropoietin(EPO) and angiotensin receptor blocker on the expression of eNOS and Bcl-2 after cerebral ischemia.Methods The model of focal cerebral ischemia was made by occluding middle cerebral artery(MCA) for 2h and reperfusing for 48h in healthy Sprague-Dawley rats.The rats received EPO 3 000u · kg-1 · d-1 or valsartan 40mg · kg-1 · d-1 by intraperitoneal injection just before the beginning of reperfusion and after reperfusion.The expression of eNOS and Bcl-2 was detected.Results Compared with ischemia group,Bcl-2 and eNOS expressions in EPO-treated group and EPO-ARB treated group were significantly increased (P ＜ 0.05).eNOS expression in ARB-treated group was significantly increased (P ＜ 0.05),Bcl-2 expression was up-regulated,but it had no significant difference.Conclusion EPO had protective effects on cerebral ischemia-reperfu-sion injury in rats,which partially mediated by up-regulating of Bcl-2 and eNOS expression.Angiotensin receptor blocker had protective effects on cerebral ischemia-reperfusion injury in rats,which partially mediated by up-regulating of eNOS expression.

ObjectiveTo observe the clinical effect of Chinese medication plus warm needling in regulating the hypothalamo-pituitary-ovarian axis (HPOA) for anovulatory infertility.MethodThe relevant clinical data of sixty-seven women with infertility were comprehensively analyzed, to summarize the risking factors for anovulatory infertility, and then the subjects were randomized into an observation group and a control groupby their visiting sequence. The control group was intervened by orally taking Bushen Tiaojing Cupailuan (tonifying kidney, regulating menstruation, and promoting ovulation) decoction, while the observation group was by warm needling in addition to taking the same decoction. The clinical efficacies, growth of endometrium, and size of follicle were compared between the two groups.ResultWarm needling plus Bushen Tiaojing Cupailuan decoction produced a positive effect in treating anovulatory infertility, andthe pregnancy rate of the observation group was significantly higher than that of the control group (P<0.05).ConclusionThe effect produced by warm needling plus Bushen Tiaojing Cupailuan decoction has a comparatively high clinical value.
