Objective To determine normal reference values for conduction in the posterior antebrachial cutaneous nerve.Methods Antidromic sensory conduction examinations of the bilateral posterior antebrachial cutaneous nerve were conducted with fifty-eight healthy subjects.The onset latency,peak latency,peak-to-peak amplitude and conduction velocity of the sensory nerve action potentials (SNAPs) were recorded and the inter-side ratios of the peak-to-peak amplitudes were calculated.Results The observed means (and standard deviations) of the onset time,the peak latency,the amplitude and the conduction velocity were 1.96 (0.12) ms,2.48 (0.14) ms,7.39 (2.36) μV and 61.39 (3.69) m/s,respectively.The side-to-side amplitude ratio (smaller/larger) was 0.88 ± 0.09,and no significant difference was observed between the left and right side.The average peak latency and amplitude were significantly different for different age groups.There was no statistically significant difference among the age groups with regard to onset latency or conduction velocity.Conclusion Conduction in the posterior antebrachial cutaneous nerve is easy to study.The peak latency is prolonged and the amplitude decreases with age,suggesting that different normal reference values should be established for different age groups.

Objective To assess the influence of community and hospital comprehensive Health management on quality of life in aged patients with coronary artery disease (CAD) after PCI.Methods 147 patients with CAD after PCI were divided into experimental group(72 cases) and control group (75 cases) accordance with their residential community.In control group,community health education was introduced.While in experimental group,hospital and community comprehensive healthy education lasted for one year.Before and after invention,major adverse cardiac events (MACE) was recorded and generic quality of life inventory (CQOLI-74),self-rating anxiety scale (SAS),and self-rating depression scale (SDS) were carried out on the basis of giving unite guiding words.Results The observation items of the SAS(34±6 vs41 ±7,t =2.714,P ＜0.01)and SDS(35 ±7 vs 41 ±8,t =2.572,P ＜0.05)scores in experimental group were lower than those in control group.Meanwhile the body health dimension(63 ± 12 vs 59 ±11,t =5.935,P ＜0.01 ),psychological health dimension(64 ± 14 vs 58 ± 13,t =6.116,P ＜0.01 ),social function dimension(64 ± 11 vs 58 ± 10,t =6.157,P ＜0.01 ) were higher than those in control group,but the difference of the material life dimension and the MACE rate were not statistically significant( P ＞0.05).Conclusions Community and Hospital comprehensive health management is a practical and valuable strategy for palliating the depression and anxiety and improving quality of life after PCI in aged patients.

Objective To estimate the test-retest reliability of limits of stability (LOS) measurement in healthy young adults. MethodsTwenty-five healthy young adults participated this study.Their center of pressure (COP) displacements were recorded while they stood on a force platform.The subjects performed maximal voluntary sway maneuvers in the anterior,posterior,left and right directions in turn.The LOS in each direction was calculated using balance clinic software.Each subject underwent 3 consecutive,identical tests at 7 day intervals with the same investigator.The test-retest reliability of LOS was analyzed using the intraclass correlation coefficient (ICC).ResultsFor the first test the ICC values ( ICC1 ) of the LOS ranged from 0.790 to 0.857.For the mean LOS of the first two tests the ICC2 ranged from 0.906 to 0.937,and for the mean LOS of three tests the ICC3 ranged from 0.910 to 0.948. ConclusionThe LOS test is a reliable measurement with healthy young adults.In clinical practice,averaging two LOS tests is suggested in assessing balance and postural control with young adults.

Among 172 patients with coronary artery disease (CAD),94 received community and hospital joint management (joint group) after percutaneous coronary intervention (PCI) for Ⅰ year and 78 received community-based health education only (control group) after PCI.The compliance of medication,readmission rate,times of hospitalization,medical costs,major adverse cardiac events (MACE),and general quality of life inventory (CQOLI-74),self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores were compared between two groups.The rate of readmission,times of hospitalization,medical costs,the sores of SAS and SDS in joint group were lower than those in control group(P ＜ 0.01 or 0.05).The compliance of medication,body health dimension,psychological health dimension and social function dimension in joint group were better than those in control group,but there were no differences in material life dimension and the MACE rate between two groups(P ＞ 0.05).Community and hospital joint management can reduce the readmission rate and medical burden,and improve quality of life for elderly CAD patients after PCI.
