ABSTRACT
Objective:To explore the mechanism of balance control after stroke by plantar pressure analysis. Methods:From July to December, 2019, twelve stroke subjects (stroke group) and 30 normal subjects (control group) were recruited in the rehabilitation department of our hospital. Both groups were measured plantar pressure in eyes open and closed conditions. The kinematic parameters, dynamic parameters, plantar pressure center (CoP), symmetry index (SI), symmetry angle (SA) and Romberg quotient (RQ) were calculated. Results:Compared with eyes open condition, the average Y and maximum swing of the control group increased significantly in eyes closed condition (P < 0.01); moreover, the ball length, average speed and maximum swing increased significantly in the stroke group (P <0.05). Compared with the control group, the area of the ellipse (|t| > 3.509, P < 0.001) and the average X (|Z|> 2.311, P < 0.05) significantly increased both in eyes open and closed condition, whereas the maximum swing (Z = -3.118, P < 0.01) increased significantly in eyes closed condition in the stroke group. The RQ of ball length was significantly more in the stroke group than in the control group (t = -3.570, P < 0.01). There was no significant difference in SI and SA of all parameters between the eyes open and closed condition in two groups (P > 0.05). Compared with the control group, load SI, overall load SI, forefoot load SI, area SI and forefoot area SI increased in both the eyes open and closed conditions in the stroke group (t > 2.344, P < 0.05), whereas load SA, overall load SA, forefoot load SA, area SA, forefoot area SA increased (|t|> 2.297, P < 0.05), hindfoot load SA increased only in eyes open condition (t = -2.485, P < 0.05), and hindfoot area SA increased only in eyes closed condition (t = -2.132, P < 0.05). In the control group, CoP was mainly distributed in the negative direction of Y axis when the eyes were open and closed, while CoP in the stroke group was relatively discrete, and the distribution on X axis was more obvious than that of the control group. Conclusion:The balance control of stroke patients might depend on visual compensation, and the plantar pressure analysis system could be used to evaluate the balance function in stroke patients.
ABSTRACT
Objective:To investigate the targeted surveillance combined with cluster management on isolation protector use rate and hand hygiene qualification rate in caregivers of patients with respiratory tract multidrug-resistant bacterial infections.Methods:Second Hospital of Shanxi Medical University began to perform targeted surveillance combined with cluster management among caregivers of patients with multidrug-resistant bacterial infections in July 2019. The caregivers of 50 patients with respiratory tract multidrug-resistant bacterial infections who were admitted before targeted surveillance combined with cluster management were included in the pre-implementation group. The caregivers of 50 patients with respiratory tract multidrug-resistant bacterial infections who were admitted after targeted surveillance combined with cluster management were included in the post-implementation group. Multidrug-resistant bacterial infections in caregivers, isolation protector use rate, environmental disinfection and hand hygiene qualification rate were compared between before and after 6 months of targeted surveillance combined with cluster management. The application value of targeted surveillance combined with cluster management in the prevention of respiratory tract multidrug-resistant bacterial infections was analyzed.Results:The number of caregivers with respiratory tract multidrug-resistant bacterial infections in the post-implementation group was lower than that in the pre-implementation group (5 vs. 13, P < 0.05). The proportion of caregivers who wear a mask (94.11%), isolation clothes (80.39%) and gloves (98.03%) in the post-implementation group was significantly higher than that in the pre-implementation group (70.00%, 62.00%, 78.00%, χ2 = 10.027, 4.911, 9.683, all P < 0.05). The proportion of caregivers who were qualified in terms of hand hygiene (82.35%), object surface (76.47%), and keeping the air fresh in the post-implementation group was significantly higher than that in the pre-implementation group (64.00%, 58.00%, 64.00%, χ2 = 4.341, 3.915, 5.450, all P < 0.05). Conclusion:Targeted surveillance combined with cluster management can effectively help prevent respiratory tract multidrug-resistant bacterial infections in caregivers and increase isolation protector use rate and hand hygiene qualification rate.

OBJECTIVE:To investigate the characteristics of adverse drug reactions(ADR)of our hospital so as to promote rational drug use in the clinic.METHODS:1162ADR cases collected during2002～2004in our hospital were analyzed retrospectively.RESULTS:The occurrence of ADR induced by combined use of drugs accounted for33.6%of the total(390cases),chiefly through IV.Altogether531kinds of drugs involved ADR,in which the anti-infective agents(110kinds)took the lead which amounted to51.3percent of the total,then came the antineoplastic agents,cardiovascular system medicines and Chinese drugs preparations.The first3drugs that involved highest frequency of ADR occurrences were levofloxacin,cefo?peazone/sulbactam and azithromycin.The main clinic manifestations of ADR were skin damage,then gastro-intestinal damage and etc.There were28serious ADR cases.CONCLUSION:The cultivation of professional ability and quality of professional staff should be strengthened and an omnibearing ADR monitoring work should be carried out so as to reduce and avoid the occurrence of ADR.
ABSTRACT
Objective To evaluate the effect of errorless learning on memory processes.Methods Eight- y-four participants were randomly divided into three groups:a group which received computer-assisted memory train- ing (CAMG,n=30) ,a therapist-administered memory training group (TAMG,n=24) and a control group (CG,n =30).A 20-session training course with a Chinese cultural background was tailor-made for Chinese subjects with memory disorders.It was administered over the course of one month to the test groups with a similar course structure and content but different delivery modes.The control group had no training.The Rivermead Behavioral Memory Test- Chinese Version (RBMT-CV) and the Hong Kong List Learning Test (HKLLT) were used to assess memory ability and process at the start and end of the training,and one month later.A repeated measures analysis of variance was used to compare differences across the three groups.Results Comparing pre-training with post-training and follow- up,RBMT-CV and HKLLT scores improved significantly.The CAMG group demonstrated better progress encoding and storage on the HKLLT (including the random and blocked conditions) than the TAMG group.Conclusions Errorless learning is likely to be an effective technique for improving memory function in patients with traumatic brain injury.Its effects last for at least one month.Computer-administered training was more effective than therapist-admin- istered face to face training,especially in improving encoding and storage memory processes.
