ABSTRACT
ObjectiveTo explore the effect of virtual reality on upper limb function in stroke patients through diffusion tensor imaging (DTI). MethodsFrom September, 2021 to March, 2023, 80 stroke patients in the Fuzhou Second General Hospital were randomly divided into control group (n = 40) and experimental group (n = 40). Both groups received routine rehabilitation, while the experimental group received virtual reality training additionally, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and Action Research Arm Test (ARAT) before treatment, after treatment and after four-week follow-up; and they were scaned with DTI to measure the fractional anisotropy (FA) and relative anisotropy (RA) of cerebral peduncle and posterior limb of inner capsule of the affected side before and after treatment. ResultsTwo cases dropped in each group. The FMA-UE and ARAT scores increased in both groups after treatment and follow-up (F > 2.790, P < 0.001), and increased more in the experimental group than in the control group (t > 2.297, P < 0.05). FA and RA in the posterior limb of inner capsule increased in both groups after treatment (t > 21.013, P < 0.001), and increased more in the experimental group (t > 2.006, P < 0.05). The d-value of FA of the posterior limb of internal capsule before and after treatment (ΔFA) was positively correlated with the d-value of FMA-UE score (r > 0.362, P < 0.05) in both groups, the ΔFA of the posterior limb of internal capsule was positively correlated with the d-value of ARAT score (r = 0.459, P < 0.01). ConclusionVirtual reality training can promote the recovery of upper limb function in stroke patients, which may associate with the conductivity of posterior limb of inner capsule.
ABSTRACT
Objective:To explore the application and effect of flipped classroom in community clinical pharmacist training.Methods:Seventeen pharmacists trained in 2017-2018 were used as the control group and received traditional teaching mode. Fourteen pharmacists trained in 2019-2020 were used as the experimental group and received the flipped classroom teaching mode. Finally, the teaching effect was evaluated through the trainees' graduation examination results and satisfaction degree. The SPSS 25.0 was used to conduct the t test and chi-square test. Results:The task performance, prescription audit scores, clinical practice scores, and total scores in the experimental group were significantly higher than those in the control group ( P<0.05). However, there was no significant difference in usual performance between the two groups ( P>0.05). For satisfaction survey, the total score of Likert scale in the experimental group was (20.1±3.4), which was significantly higher than that in the control group (16.9±3.4). However, there was no significant difference in the satisfaction of clinical practice and teachers' level between the two groups ( P>0.05). Conclusion:Flipped classroom can improve the enthusiasm of community clinical pharmacist trainees to participate in learning, increase the level of the trainees' theoretical knowledge and professional practice, and is conducive to the cultivation of high-quality community clinical pharmacists.
ABSTRACT
Objective To investigate the risk of fatal stroke mortality associated with short-term exposure to air pollution， and to determine the susceptible population. Methods In this study， daily stroke mortalities of adults between 2012 and 2014 in Songjiang District， Shanghai were collected. Time-stratified case-crossover approach was used to assess the association between daily concentrations of air pollutants and fatal stroke mortalities. Results This study included 514 patients who died from acute strokes. The average concentrations during the study period were 77.45 μg·m-3 for PM2.5， 21.22 μg·m-3 for SO2， and 57.59 μg·m-3 for NO2. The fatal stroke mortality of adults under the age of 65 was found to be significantly associated with NO2. At the time of a Lag of 2 d and 03 d， a significantly higher risk of fatal stroke mortality in relation to NO2 exposure was observed， and the OR values of ischemic stroke mortality for people were 3.86 （1.53-9.75） and 5.83 （1.40-24.34） respectively. People over the age of 65 were more sensitive to increased PM2.5 concentrations， at the time of a Lag of 03 d， fatal strokes increased by 28% when PM2.5 levels increased. A significantly higher risk of fatal stroke mortality in relation to increase of NO2 concentration was observed among people who were overweight or obese. Conclusion A significantly higher risk of fatal stroke mortality is associated with the increase of PM2.5 and NO2. The results also suggest that the susceptible population should take additional precautions to avoid or reduce the risk of fatal strokes.
ABSTRACT
OBJECTIVE:To compare the effectiveness and safety of low-molecular-weight-heparin(LMWH)calcium and rivar-oxaban in preventing lower extremity deep venous thrombosis (DVT) in the elderly patients after surgery of replacement of frac-ture. METHODS:A total of 58 elderly patients underwent hip or artificial femoral head replacement were randomly divided into LMWH group (29 cases) and Rivaroxaban group (29 cases). All patients received basic prevention and physical prevention for DVT after surgery. Based on this,LMWH group was given Heparin calcium injection 4100 IU subcutaneously 10 h after surgery, for 10 d. Rivaroxabar group was given Rivaroxaban tablet 10 mg 10 h after surgery,once a day,for consecutive 10 d. The occur-rence of DVT and positive D-dimer were observed in 2 groups after surgery. The PT,APTT,TT,FIB and platelet counts abnormal-ity were also observed in 2 groups. RESULTS:There was no statistical significance in the incidence of DVT,the occarrence of pos-itive D-dimer,PT,APTT,TT,FIB and platelet counts abnormality 4,10 d after surgery between 2 groups(P>0.05). CONCLU-SIONS:LMWH and rivaroxaban both can be used for lower extremity DVT in the elderly patients after replacement of fracture sur-gery of and have similar therapeutic efficacy and safety.
