Objective To investigate the influence of mannitol and glycerin injection (containing 15％ mannitol and 15％ glycerin) on experimental intracranial hypertension.Methods Rabbits were randomly divided into eight groups (n =8 rabbits/group):normal control group,model control group,mannitol-glycerol injection groups (2.5 ml/kg group,5 ml/kg group,and 10 ml/kg group),compound mannitol injection fluid group,20％ mannitol group,and 10％ glycerol-sodium chloride injection group.The continuous intravenous infusion of nitroglycerin [0.04 mg/(kg · min),10 min] on rabbits was used to establish intracranial hypertension model except the normal control group of animals,and effect of mannitol glycerol injection on it with a single intravenous injection was observed.Serum renal function,electrolytes and other indicators were tested.Results Intravenous infusion of mannitol glycerol injection (2.5 ml/kg,5 ml/kg,and 10 ml/kg) could significantly reduce rabbit nitroglycerin-induced intracranial hypertension,and dosedependent,with increasing dose reducing intracranial pressure could enhance(P ＜ 0.05).Mannitol glycerol injection (5 ml/kg) produced the same intracranial pressure compared to 20％ mannitol and compound mannitol injection,and maintained a long-time role.Conclusions Mannitol glycerin injection can significantly reduce intracranial pressure.Its intensity is the same as 20％ mannitol and compound mannitol injection,and maintains a longer intracranial pressure without significant renal dysfunction and electrolyte distnrhances.

Objective To investigate the differences in the curative effects between traditional telephone follow-up and medical care combined with WeChat and medical mobile app in adult epilepsy patients with anxiety and depression,analyze the influence factors for the differences from following five aspects: medication compliance, anxiety and depression,quality of life of patients, knowledge of diseases and related behavior correction,satisfaction rate of patients to follow-up and patients' hospital readmission rate. Methods A total of 100 adult epilepsy patients with anxiety and depression in our department from February 2015 to October 2015 were investigated in the study. The patients were divided into observation group and control group by admission order alternates (50 respectively). Patients in control group received traditional telephone follow-up,while patients in observation group were managed using WeChat and medical mobile APP. Medication compliance,anxiety and depression,quality of life of patients,knowledge of diseases and related behavior correction, satisfaction rate of patients to follow-up and number of patients' hospital readmission were compared between two groups at intake time and after 6 months' follow-up. Results Among 100 epilepsy patients, 14 patients were lost and 86 patients were followed up for 6 months. At 6 months' post discharge, medication compliance of patients in observation group was significantly higher than that in control group (P<0.05). The scores of SAS and SDS in observation group were lower than those in control group, with statistically significant difference (P<0.05). The score of QOLIT-31 in observation group was significantly higher than that in control group (P<0.05). Patients in observation group performed better than patients in control group in diet habit correction, knowledge of training methods, as well as in satisfaction to follow-up and rate of patients' hospital readmission. The differences were statistically significant (P<0.05). Conclusions Medical care combined with WeChat and medical mobile APP in adult epilepsy patients with anxiety and depression can improve patients' medication compliance, relieve patients' anxiety and depression, increase quality of life of patients, enhance patients' knowledge of disease and behavior correction and raise the rate of patients' hospital readmission and satisfaction to follow-up.
