ABSTRACT
Objective:To investigate the application effect of workshop in pediatric intravenous indwelling needle training for nursing undergraduates.Methods:A total of 214 undergraduate nursing interns were randomly divided into experimental group ( n=106) and control group ( n=108). Workshop teaching model was used in the experimental group, while the traditional teaching model in the control group. Clinical Decision Making in Nursing Scale (CDMNS), General Self-efficacy Scale (GSES) and theoretical assessment of the two groups were compared respectively before and after training, and operation evaluation was performed after training. Results:Scores of GSES, theory and operation evaluation in the experimental group were all higher than those in the control group with statistically significant differences ( P<0.05). The scores of clinical decision-making awareness was higher in the experimental group than in the control group, but the difference was not statistically significant ( P>0.05). Conclusion:Application of workshop teaching model in the training of pediatric patients with intravenous indwelling needles could enhance nursing students' self-efficacy, theoretical and operational achievements, thus improve the teaching quality.
ABSTRACT
Objective To compare the efficacy of ozone injection plus electrothermal acupuncture versus oral glucosamine and nimesulide in treating knee osteoarthritis and investigate the effects of the two treatments on the WOMAC total score and the pain, stiffness and physical function scores.Method Eighty patients with knee osteoarthritis were randomly allocated to combination and Western medicine groups, 40 cases each. The combination group received a combined treatment with intra-articular ozone injection and electrothermal acupuncture and the Western medicine group took glucosamine hydrochloride and nimesulide sustained-release tablets. The WOMAC score was recorded in the patients before and after treatment. The therapeutic effects were evaluated using the WOMAC score. Result The control and marked efficacy rate of ozone injection plus electrothermal acupuncture for knee osteoarthritis was higher than that of Western medicine. The WOMAC score decreased in both groups after treatment (P0.05). The physicalfunction score decreased more in the combination group than in the Western medicine group (P<0.05).Conclusion Ozone injection plus electrothermal acupuncture is more effective than Western medicine in treating knee osteoarthritis. It is more effective in improving knee function but not in relieving the pain and joint stiffness in comparison with Western medicine.
ABSTRACT
Intestinal barrier dysfunction and autophagy abnormality play important roles in the mechanism of inflammatory bowel disease, however, whether autophagy has effect on intestinal barrier dysfunction has not been reported.Aims: To explore the effect of autophagy inducer pp242 on intestinal barrier dysfunction induced by tumor necrosis factor-α (TNF-α).Methods: Model of intestinal epithelial monolayer barrier was established with Caco-2 cells in Transwell chambers, and then randomly divided into four groups: control group (without any intervention), TNF-α group (10 ng/mL TNF-α), pp242 group (1 μmol/L pp242), TNF-α+pp242 group (10 ng/mL TNF-α+1 μmol/L pp242).The intestinal barrier function was evaluated by transepithelial electrical resistance (TEER) and flux of FITC-dextran.The protein expressions of autophagy related protein LC3B-Ⅱ and p62 were detected by Western blotting.Results: Compared with control group, TEER was significantly decreased (P<0.05), flux of FITC-dextran, protein expressions of LC3B-Ⅱ and p62 were significantly increased in TNF-α group (P<0.05).Compared with TNF-α group, TEER was significantly increased (P<0.05), protein expression of LC3B-Ⅱ was significantly increased (P<0.05) while protein expression of p62 was significantly decreased in TNF-α+pp242 group (P<0.05).Conclusions: Autophagy inducer pp242 relieves TNF-α-induced intestinal epithelial barrier dysfunction via activating autophagy flux.
ABSTRACT
Objective To compare the efficacies of electrothermal needle acupuncture versus nimesulide in treating knee osteoarthritis and the relieving effects of them on the pain and explore the possible mechanism of electrothermal needle treatment for knee osteoarthritis.Method Eighty patients with knee osteoarthritis were randomly allocated to electrothermal needle and Western medicine groups, 40 cases each.The electrothermal needle group received electrothermal needle therapy and the Western medicine group took nimesulide sustained-release tablets.The therapeutic effects were compared after thecompletionof treatment.Therelieving effects of the two treatments on the pain were evaluated using the Pain Visual Analogue Scale(VAS).Serum SOD and MDA were measured in all the subjects before and after treatment.Result The marked efficacy rate and the total efficacy rate for knee osteoarthritis were higher in the electrothermal needle group than in the Western medicine group.There was no significant post-treatment difference in the VAS pain score between the electrothermal needle and Western medicine groups.After treatment, serum SOD increased and MDA decreased in the electrothermal needle group and they did not change significantly in the Western medicine group.Conclusion Electrothermal needle therapy can well relieve the symptoms of knee osteoarthritis.Its relieving effect on the pain is equal to that of nimesulide.The mechanism of electrothermal needle treatment for knee osteoarthritis may be relatedto its improving bodilyoxidative stress levels.
ABSTRACT
OBJECTIVE:To prepare Baicalin proliposomes (PBA) containing sodium deoxycholate (SD) with optimized for-mulation,and to study pharmacokinetics of it in rats in vivo. METHODS:PBA were prepared by spray drying method. Response surface method based on Box-behnken design was adopted to optimize the formulation of PBA with the amount of HSPC,cholester-ol and SD as factors using entrapment efficiency of PBA as index. The particle size,morphology,leakage rate and stability of the optimal PBA were evaluated along with the pharmacokinetics of it(compared to raw materials)in rats after ig administration of 15 mg/kg. RESULTS:The optimal formulation of PBA was that the amounts of baicalin,HSPC,cholesterol and SD were 100,214, 68 and 53 mg,respectively;the predicted and practical values of entrapment efficiency were 86.42% and 84.32%,respectively, and particle size of the optimal PBA was 358.4 nm. The leakage rate of reconstituted liposomes was low and the stability of PBA was good. Compared with baicalin raw material,t1/2,tmax,MRT,cmax and AUC0-t of PBA were all increased significantly(P<0.05 or P<0.01 or P<0.001). CONCLUSIONS:PBA were prepared successfully using the spray drying method. This method is simple and easy,and the optimized formulation is feasible and can improve the oral bioavailability of baicalin.
ABSTRACT
Objective To explore the impact and mechanism of miR-200 b on intestinal epithelial tight junction. Methods The negative-lentivirus and human-miR-200 b-lentivirus were employed to infect the Caco-2 cell thus establishing two stable cell lines which were then stimulated by 10 ng/mL human tumor necrosis factor-α(TNF-α) to establish the model of the intestinal epithelial injury. Those Caco-2 cells were divided into NC, NC+TNF-α, 200b, and 200b+TNF-αgroups.The tight junction permeability was detected by transepithelial electrical resistance (TEER) and Fluorescein isothiocyanate-labeled dextran (FITC-dextran). The protein alterations myosin light chain kinase (MLCK)/phosphorylated myosin light chain (P-MLC) pathways were measured by Western blot analysis. Results Compared to NC group, NC+TNF-αgroup had lower TEER, higher FITC-dextran, and up-regulated expressions of MLCK and P-MLC proteins (P

ABSTRACT
PBL teacheing mode has satisfactory postive influence to the learning motivation,because it has a different characteristic compared with the traditional teaching mode,and can stimulate the curiosity and the desire of learning more effectively,thus arousing the initiative of the students. It can also cultivate their spirit of master and consciousness of responsibility more effectively,and it is beneficial to teaching students in accordance with their aptitude and developing their personality.In the course of the PBL teaching mode,the principles of moderate difficulty,precise occasion,in association with practice and encourage by feedback should be paid enough attention to.
