Objective:To explore the effects of "rain classroom" wisdom teaching on geriatric students′ autonomous learning ability and self-efficacy.Methods:From June to August, 2021, 61 nursing students who practiced in the department of gerontology of the Second Xiangya Hospital, Central South University were selected as research subjects, and divided into experimental group (30 students) and control group (31 students) by random number table method. In the experimental group, wisdom teaching based on "Rain classroom" was carried out at the same time as conventional teaching, while in the control group, conventional teaching was carried out, and the teaching effect was evaluated by the independent learning ability measurement scale and academic self-efficacy scale of nursing students.Results:The score of autonomous learning ability of nursing students in the experimental group was 68.55 ± 11.06, and that in the control group was 74.29 ± 9.16. The difference between the two groups was statistically significant ( t = -2.01, P<0.05). The academic self-efficacy scores of nursing students in experimental group and control group were 52.27 ± 11.56 and 52.64 ± 9.28 respectively. There was no significant difference between the two groups ( P>0.05). Conclusions:The wisdom teaching of "rain classroom" improves the independent learning ability of geriatric nursing students, and attaches importance to the cultivation of self-efficacy of nursing students, and the improvement of self-efficacy needs further research.

Objective To prepare the sunscreen lipstick in order to prevent UVA and UVB.Methods The ratio of bees-wax,castor oil and liquid paraffin were optimized with the orthogonal test based on viscosity and heat resistance.The spread-able ability,stability and the anti-ultraviolet effect of the optimized lipstick were investigated.Results The best ratio of bees-wax,castor oil and liquid paraffin was 8:5:4(w/w/w).The viscosity of the sunscreen lipstick was appropriate,easy to spread and stable,which was demonstrated the good prevention effect from UVA and UVB.Conclusion The advantages of the prepared sunscreen lipstick included simple preparation,low cost and stable quality.It could be a new type of sunscreen lipstick protecting from UVA and UVB.

Objective To compare the improvement effect of three physical techniques on the transdermal absorption of sinap?ine thiocyanate(ST)in vitro,including microneedles,sonophoresis and iontophoresis,and to evaluate the mechanism and rules of physcial techniques on the transdermal absorption of poorly transdermal absorbed drugs. Methods In vitro transdermal experiment was carried out under the circumstances of microneedles,sonophoresis or iontophoresis,using the modified Franz diffusion pool. The 2 mg/ml ST solution was adopted as the donor solution, and the SD rats′abdomen skin was used as the model skin. Sampling was car?ried out at the predetermined time points and each sample was analyzed by HPLC. Cumulative transdermal amount and steady transder?mal absorption rate were calculated. Pathological slides were made after the skins were treated with microneedles ,sonophoresis and iontophoresis for 12 h. The structure changes were observed to evaluate the transdermal improvement mechanism of different technolo?gies. Results Accumulated transdermal amount of ST was little without any techniques. The transdermal improvement effect of differ?ent technologies was as follows:microneedles>sonophoresis>iontophoresis. A substantial hole formed on the skin by microneedles to promote ST transdermal absorption obviously. Sonophoresis disrupted the tight structure of skin and improved the transdermal absorp?tion of drugs easily. The effect of iontophresis on skin structure was little. Conclusion This study provides experimental evidence for choice of different techniques to improve transdermal absorption.

OBJECTIVE:To explore the effect of dabigatran etexilate on coagulation indexes and safety of elderly patients with persistent atrial fibrillation. METHODS:52 elderly patients with persistent atrial fibrillation were randomly divided into obser-vation group and control group by random number table,26 cases in each group. Creatinine clearance rate in observation group was higher than 30 ml/min,110 mg Dabigatran etexilate capsule was orally given,bid;when 15-30 ml/min,55 mg capsule was orally given,bid. Control group orally received Warfarin sodium tablet with initial dose of 2.5 mg,qd,according to international normal-ized ratio (INR) after 3-5 days till maintained in 2.0-3.0. After 3 months,coagulation indexes [prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time (TT),INR,platelet count (PLT),fibrinogen (FIB)] before and after treat-ment,incidences of clinical events (cerebral embolism,cerebral hemorrhage,fatal bleeding,the remaining parts of embolism, death)and adverse reactions in 2 groups were compared. RESULTS:There was no significant difference in PT,APTT,TT,PLT and FIB between 2 groups before treatment(P>0.05);after treatment,PT and INR in 2 groups significantly increased,and obser-vation group was obviously better than control group,the difference was statistically significant(P0.05);the incidence of remaining parts of embolism,death in observation group significantly lower than control group,the difference was statistically significant(P<0.05). The incidence of adverse reactions in observation group was significant-ly lower than control group,the difference was statistically significant (P<0.05). CONCLUSIONS:Dabigatran etexilate shows good coagulation effect on elderly patients with persistent atrial fibrillation,which can effectively improve PT and INR levels and reduce the incidences of clinical events,with good safety.
摘要
To better evaluate neuromuscular function of patients with stroke related motor dysfunction, we proposed an effective corticomuscular coherence analysis and coherent significant judgment method. Firstly, the related functional frequency bands in the electroencephalogram (EEG) were extracted via wavelet decomposition. Secondly, coherence were analysed between surface electromyography (sEMG) and sub-bands extracted from EEG. Further more, a coherent significant indicator was defined to quantitatively describe the similarity in certain frequency domain and phase lock activity between EEG and sEMG. Through the analysis of corticomuscular coherence during knee flexion-extension of stroke patients and healthy controls, we found that the stroke patients exhibited significantly lower gamma-band corticomuscular coherence in performing the task with their affected leg, and there was no statistically significant difference between their unaffected lag and the healthy controls, but with the rehabilitation training, the bilateral difference of corticomuscular coherence in patients decreased gradually.
