The paper introduces the formation, current status and developing strategies of E - reading room open information service, and points out that this kind of service has become new model of library service in information era.

Objective:To study the Raman spectrum and the surface enhanced Raman spectrum ( SERS) of cefalexin, cefadroxil and cephradine, and analyze the surface enhanced Raman spectrum of the three compounds under different pH conditions. Methods:The Raman spectrum and the surface enhanced Raman spectrum of the three compounds under different pH conditions were detected and measured by a portable Raman spectroscopy. Results: The results showed that the three compounds could exhibit characteristic peak information in the surface enhanced Raman spectroscopy corresponding to that in the normal Raman spectrum, and the pH values had certain impact on the surface enhanced Raman spectrum of the three substances. Conclusion: Both the Raman spectrum and the surface enhanced Raman spectrum of cefalexin, cefadroxil and cephradine reflect certain fingerprint characteristics, and it is feasible to use Raman scattering method to identify the three cephalosporins.

Objective To explore the effect of peer-education on self-efficacy of hemodialysis(HD) patients. Methods Totally 90 HD patients were divided into two groups equally. The intervention group received peer-education for 3 months and the control group received routine nursing. The two groups were compared in terms of score on self-efficacy. Results There was no statistically significant difference in the score on self-efficacy and every item between the two groups before intervention (P>0.05). The score on self-efficacy and the items ofcontrol of depressive mood, the confidence in taking self-care measures, the confidence in doing other thingswere statistically significantly different between the two groups after intervention (P<0.05). Conclusion Peer-education can improve HD patient′s self-efficacy.

Glabridin (Glab) is an isoflavonoid originally isolated from the roots of Glycyrrhiza glabra L. (Fabaceae). Glab is widely considered to be a phytoestrogen and has been associated with numerous biological properties ranging from antioxidant, anti-inflammatory, neuroprotective, anti-atherogenic effects, to the regulation of energy metabolism. In this paper, a review on its biological activity was reviewed.

Objective:To explore the effect of micro-video education combined with active psychological management on the rehabilitation effect of hip replacement.Methods:From January to December 2018, 100 patients with total hip arthroplasty were divided into control group and observation group, 50 cases in each group. The control group was given routine nursing, and the observation group was given micro video education combined with positive psychological management. The depression, pain, joint function and complications were evaluated.Results:After the intervention, the Self-rating Depression Scale (SDS) score of patients in the observation group was (34.72±6.83) points, which was significantly lower than (40.58±7.59) points of the control group. The difference was statistically significant ( tvalue was 4.058, P<0.05); pain control education in the observation group and satisfaction scores for pain control or reduction methods were (43.01±5.72) and (63.77±8.62) points respectively, which were better than the control group's (33.96±4.58) and (55.15±9.27) points. The difference was statistically significant ( tvalues were 8.733, 4.815, P<0.05); the excellent and good rate of hip joint function in the observation group was 90.00% (45/50), which was higher than 64.00% (32/50) in the control group. The difference was statistically significant ( χ 2value was 4.336, P<0.05); the complication rate in the observation group was 2.00% (1/50), which was significantly lower than the control group's 18.00% (9/50). The difference was statistically significant ( χ 2value was 7.111, P<0.05); The scores of each item of quality of life in the observation group were higher than those in the control group, and the differences were statistically significant ( tvalues were- 9.859 to- 3.154, P<0.01). Conclusion:Micro video education combined with positive psychological management can improve the depression of patients after hip arthroplasty, reduce the degree of joint pain, promote the function of hip joint and reduce complications.

0.05).A similar amount of propofol was used in each group.A significantly higher dose of sufentanil was administered in the Group C(73.9?13.6 ?g)than in the Group A(24.3?4.9 ?g)and the Group B(35.4?8.1?g)(qC-A=237.924,P=0.000;qC-B=119.385,P=0.000).The expected time of recovering consciousness was shorter in the Group A and B than in the Group C.Conclusions Administered by target-controlled infusion with propofol,sufentanil dose-dependently reduces BIS and modifies hemodynamic responses during anesthesia induction.The target effect-site sufentanil concentration of 0.6 ng/ml combined with plasma propofol concentration of 3 ?g/ml is suitable for anesthesia induction for short-time laparoscopic operation.

Late in-the-bag dislocation of intraocular lens bag complex is a rare but potential complication after cataract surgery,which can affect the quality of patients'life seriously,and usually need surgical treatment.People are paying more attention to this complication,because it has been reported with increasing frequency in recent years.This complication may present after a long time frame.There is a research showing that the interval between cataract surgery and the dislocation was 10.9 years.The cumulative risk of IOL dislocation at 10 years,20 years,and 25 years after cataract extraction was 0.1％,0.7％,and 1.7％ respectively.Late in-the-bag IOL dislocation is a result of progressive zonular dehiscence up to many years after cataract surgery,and its genesis is multifactorial.This article reviews the incidence,possible mechanism and risk factors of late in-the-bag IOL dislocation.

Objective To investigate the effect of mesalazine on the expression of TNF-α, IL-6, IL-17 and intestinal barrier function in patients with ulcerative colitis. Methods 76 patients with UC from January 2015 to April 2016 in The Fifth Central Hospital of Tianjin were collected and randomly divided into control group and observation group with 38 cases in each group. After admission were given maintenance of water and electrolyte, basic acid-base balance and nutritional support treatment, and the control group were treated with conventional drug sulfasalazine (SASP) treatment, two tablets each time, four times once day, four weeks for each course, the observation group was treated with mesalazine, four tablets each time, three times once day, four weeks each course of treatment. The levels of TNF-α, IL-6, IL-17, L/M and Baron endoscopic scores in the two groups were observed after two courses of treatment. The efficacy and side effects of the two groups were compared. Results No dropout or dropout cases in this study, two groups after the treatment of TNF-α, IL-6, IL-17, L/M, Baron scores were significantly decreased (P<0.05), but the observation group after treatment the above indexes were all significantly lower than the control group (P<0.05), the total effective rate of the observation group was 89.47%(34/38) higher than that of the control group 71.05%(21/38), the adverse reaction rate of 13.16% (5/38) was lower than that in the control group 34.21% (13/38), the differences were statistically significant(P<0.05). Conclusion Compared with conventional drug SASP, the effect of on the expression of TNF-α, IL-6 and IL-17 in serum of patients with UC and the improvement of intestinal barrier function can be effectively suppressed, which has the advantages of clinical efficacy and low adverse reaction rate.
