ABSTRACT
Objectives To investigate the effect of different physical activities on the blood pressure in elderly patients with hypertension,and to provide evidence for the prevention and treatment of hypertension.Methods 256 elderly patients with grade 1,2 hypertension and no other complications,and 256 healthy elderly people were selected as the control subjects.According to the blood pressure and the level of physical activity,the patients were divided into hypertension combined with low physical activity group(HL group),hypertension combined with middle physical activity group(HM group),normal blood pressure combined with low physical activity group(NL group)and normal blood pressure combined with middle physical activity group (NM group).The changes of blood pressure were compared in quiet,during and after physical activity.Results The diastolic blood pressure(DBP) and systolic blood pressure(SBP) measured at rest,peak exercise and 5 minutes after exercise were significantly higher in group HL and HM group than in NL group and NM group,and the differences between groups were statistically significant(SBP:F=11.846、18.337、10.976,all P＜ 0.001 for all;DBP:F=13.182、11.694、11.453,all P＜0.05).The DBP and SBP in HL group at rest and 5 minutes after exercise were significantly higher than those in the HM group,and the difference was statistically significant(P＜0.05).The change magnitudes of DBP and SBP were significantly lower in HL group than in the HM group,and the differences were statistically significant (P ＜ 0.05).Conclusions Taking part in an appropriate exercise can improve blood pressure level and a recovery capability of post-exercise blood pressure in elderly patients with hypertension.
ABSTRACT
OBJECTIVE:To reduce the error rate of inventory in the automated pharmacy of our hospital. METHODS:Activi-ties were designed and implemented by the management method of quality control circles(QCC)-PDCA(Plan,Do,Check and Ac-tion)cycle. The reasons for the errors of inventory in the automated pharmacy were analyzed to investigate and implement counter-measures. Visible and invisible achievements were evaluated,and then standardized processes were made. RESULTS:The errors of inventory in the automated pharmacy mainly included those of drug dispensing,drug shelving,drug return sheet,automatic medi-cine dispensing machine and system. In view of the above reasons,relevant standards were formulated and performed,including the process of warehouse-out check and shelving of drugs,drug dispensing process for the automated pharmacy,the process of sec-ondary check,etc. After the implementation of the activities,the error rate of inventory in the automated pharmacy reduced from 9.17% to 3.77%,which was visible achievement;and the above-mentioned standardized processes could ensure continuous run-ning of PDCA cycle. The practice,sense of responsibility,communication and coordination of management members in PDCA cy-cle namely invisible achievements were improved to some extent. CONCLUSIONS:The management method of QCC-PDCA cycle is feasible in reduction of the error rate of inventory in the automated pharmacy,which can provide a reference for automated phar-macy management.
ABSTRACT
BACKGROUND:Peri-fracture nerve injury can inhibit osteoclast activity and promote early fracture healing. OBJECTIVE:To investigate dynamical y the effects of traumatic brain injury on the bone mineral density, microstructure, biomechanics property and bone metabolism in rat models of fractures. METHODS:Sixty-three male rats were randomly divided into three groups:sham group, simple fracture group and fracture combined with brain injury group. After 3, 6, and 3 months, the animals were sacrificed in batches under anesthesia, and then, the bones and serum specimens were used to detect the bone mineral density, microstructure, biomechanics property, serum cross-linked N-telopeptide of col agen type I and osteocalcin levels. RESULTS AND CONCLUSION:Compared with the simple fracture group, the fracture combined brain injury group had significantly increased bone mineral density of the proximal tibia, bone volume fraction of the cancel ous bone, trabecular thickness, cross-sectional area of tibial cortical bone and total area of the bone marrow, ultimate load and stress of the tibia, serum cross-linked N-telopeptide of col agen type I and osteocalcin levels at 3 and 6 weeks after modeling (P<0.05), but no differences in the above-mentioned indexes were found among the three groups at 3 months after modeling. These findings indicate that traumatic brain injury can increase the bone mineral density at the fracture site, improve bone microstructure and enhance biomechanical properties, thereby promoting bone healing and bone metabolism at the fracture site.
