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.

While the field of ATP synthase research has a long history filled with landmark discoveries, recent structural works provide us with important insights into the mechanisms that links the proton movement with the rotation of the Fo motor. Here, we propose a mechanism of unidirectional rotation of the Fo complex, which is in agreement with these new structural insights as well as our more general ΔΨ-driving hypothesis of membrane proteins: A proton path in the rotor-stator interface is formed dynamically in concert with the rotation of the Fo rotor. The trajectory of the proton viewed in the reference system of the rotor (R-path) must lag behind that of the stator (S-path). The proton moves from a higher energy site to a lower site following both trajectories simultaneously. The two trajectories meet each other at the transient proton-binding site, resulting in a relative rotation between the rotor and stator. The kinetic energy of protons gained from ΔΨ is transferred to the c-ring as the protons are captured sequentially by the binding sites along the proton path, thus driving the unidirectional rotation of the c-ring. Our ΔΨ-driving hypothesis on Fo motor is an attempt to unveil the robust mechanism of energy conversion in the highly conserved, ubiquitously expressed rotary ATP synthases.

Objective To investigate the clinical outcomes of flupenthixol melitracen on refractory asthma with anxiety and/or depression.Methods 105 patients with refractory asthma,who were given asthma controlled test (ACT) and comprehensive hospital anxiety and depression scale (HAD)test,were randomly classified into control group and treatment group,the former used recommended classical drugs in the consensus,Salmeterol Xinafoate and Fluticasone Propionate and Montelukast;while the latter used above therapy combining flupentixol melitrace.HAD score,ACT score and pulmonary function were applied to assess therapeutic effect.Results In 105 cases of refractory asthma patients,75 patients were complicated with anxiety and/or depression,with prevalence of 71.42％.With the alleviation of anxiety and/or depression,the degree of asthma controlled was improved.After treatment,HAD score of the treatment group was lower that of control group((10.67±2.32) scores vs (11.94±3.02) scores,t=2.06,P＜0.05),ACT score in treatment group was much higher than that of control group((14.54± 3.14) scores vs (11.25±3.06)scores,t=4.59,P＜0.01),there were statistical significance in FEV1％ pre between two groups ((55.29±5.72) vs (43.36±7.13),t=8.02,P＜0.01).Conclusion Antidepressant treatment can alleviate anxiety and/or depression,improve the clinical curative effect of refractory asthma and help to improve lung function.
