Objective To approach the effect of bed exercise for patients with intracranial aneurysm undergoing neural interventional treatment. Methods Ninety-six patients with intracranial aneurysm were divided into the test group(50 cases) and control group(46 cases).The control group received routine nursing, while the test group carried out bed exercise base on routine nursing. The incidence of complica-tions and changes of life quality were compared between the 2 groups. Results Lower incidence of com-plications took place in the test group than the control group(P ＜ 0.05).But changes in pulse rate and blood were not significant (P ＞ 0.05).The score of life quality in the physical domain and psychological domainwere not statistically different between the two groups (P ＜ 0.01 ),but no evident difference was seen in the domain of social relationship and environmental domain (P ＞ 0.05). Conclusions Bed exercise could al-leviated the anxiety and trepidation of patients with intracranial aneurysm,decrease the incidence of compli-cations such as body pain caused by absolute bed rest,thus improve patients' life quality.

Objective: To investigate and analyze the performance of informed consent of self-expense medical expenses by medical staff. Methods: By using stratified random method, a sample of 480 medical records of medical insurance patients was selected from 40 wards of a third class A hospital in Zhejiang province in 2016. Combined with semi-open questionnaire, the performance of medical staff was investigated to do informed consent of self-expense medical expenses. Results: In general, the rate of informed consent was low, and only the rate of informing bed fee was over 70％. Medical staff thought that the effective performance of informed consent was affected by many factors, such as subjective and objective factors. Conclusion: There are still some problems in the performance of informed consent of self-expense medical expenses. It is necessary to take multi-party linkage and multi-measures interventions to improve the rate of informed consent.

Objective To observe the effects of penetrance,different time of onset and mutation sites on retinal nerve fiber layer (RNFL) and macular thickness in patients with Leber's hereditary optic neuropathy (LHON).Methods This was a cross-sectional observational study.A total of 88 patients with LHON and 1492 relatives of the maternal relatives (gene carriers) who received treatment in People's Liberation Army General Hospital from 2015 to 2017 were included in the study.Among the 1492 family members,there were 694 males and 798 females.Peripheral venous blood was extracted from all subjects for mitochondrial DNA testing,and penetrance was calculated.A total of 117 patients underwent BCVA and SD-OCT examinations,including 82 patients and 35 gene carriers.The BCVA examination was performed using the Snellen visual acuity chart,which was converted into logMAR visual acuity.The thickness of RNFL,ganglion cell complex (GCC) and inner limiting membrane (ILM)-RPE were measured with OCT instrument.The mean follow-up was 50.02± 86.27 months.The disease course was divided into 6 stages including ≤3 months,4-6 months,7-12 months and ＞ 12 months.The thickness of RNFL,GCC and ILM-RPE in patients with different time of onset and mutation sites were comparatively analyzed by covariance analysis.Categorical variables were expressed as a percentage,and the x2 test was used for comparison among multiple groups.Results Among the 1492 family members,285 were diagnosed with LHON and highly suspected clinical manifestations (19.10％),including 190 males (21.98％) and 95 females (11.90％).The total penetrance rates of 11778,14484 and rare mutation sites were 19.84％ (228/1149),20.50％ (33/161),and 13.19％ (24/182) respectively;male penetrance rates were 28.87％ (153/530),27.28％ (20/72),and 18.48％ (17/92) and female penetrance rates were 12.12％ (75/619),14.61％ (13/89) and 7.78％ (7/90).There was no significant difference in total (x2=4.732),male (x2=4.263) and female (x2=4.263) penetrance between different mutation sites (P=0.094,0.110,0.349).Compared with non-pathogenic carriers,the thickness of the RNFL,GCC and ILM-RPE were all different in the four stages (≤3months,4-6 months,7-12 months and ＞12 months).The thickness ofRNFL,GCC and ILM-RPE decreased with the time of onset (P=0.000).There were significant differences in the thickness of each of the GCC and ILM-RPE layers in the macular area of LHON patients with different mutation sites (P＜ 0.05).Among them,the site 11778 and 3460 had the most severe damage in all quadrants of macular GCC and ILM-RPE layer,followed by 14484 site,and the rare site had the least damage in all quadrants.Conclusions The penetrance of LHON patients is 19.10％.With the extension of the onset time (within 1 year),the RNFL layer of the optic disc and all quadrants of the macular GCC and ILM-RPE layer gradually thinned.Compared with 11778 and rare site,14484 site,and the rare site had the lighter damage on the thickness of RNFL,GCC and ILM-RPE.
