Investigation and analysis on status quo of pressure ulcer and other skin injuries among inpatients in Class Ⅲ Grade A hospitals in Hainan province / 中国实用护理杂志

Objective To investigate and analyze the prevalence of pressure ulcer and other skin injuries, and the implementation of pressure ulcer prevention measures among inpatients in Class ⅢGrade A hospitals in Hainan province. To provide basis for fomulating bundle of care model to prevent and intervent pressure ulcer, and establishing early warning management model on nosocomial pressure ulcer in ClassⅢGrade A hospitals in Hainan province. Methods A cross-sectional survey was conducted on inpatients from 7 ClassⅢGrade A hospitals in Hainan province. A investigation was performed by a self-designed inpatients'questionnaire and qualified tools on pressure ulcer and other skin injuries. Statistical analysis of data using by SPSS19.0 software. Results The content validity index of the self-designed inpatients'questionnaire and qualified tools on pressure ulcer and other skin injuries was 0.91, Cronbach α coefficient was 0.93. The prevalence of pressure sores was 2.28% (165/7 248), of which 66.06% (109/ 165) was family involvement, 30.30% (50/165) was hospital acquired, 3.03% (5/165) was community involvement,and 0.61% (1/165) was both from family and hospital acquired. Medical instrument related pressure ulcer accounted for 18.18%(30/165) of the total number of pressure ulcer. The most common site of pressure ulcer was the sacrococcygeal region, accounting for 47.94% (93/194). The proportion of pressure ulcer in stageⅡwas the highest (35.57% , 69/194). 52.01% (647/1 244) of patients at risk of pressure ulcer did not use the anti-pressure devices,and 81.40% (1 013/1 244) of patients' main compression sites were not covered by dressings.35.50%(442/1 244) of patients did not according to plans or regularly turn over, only 56.19% (699/1 244) patients turned over every 2 hours. 61.57% (442/1 244) patients who have pressure ulcer did not have anti-pressure ulcer signs. Among other skin injuries: the prevalence of incontinence related dermatitis was 0.88%(64/7 248), and the prevalence of avulsion skin injury was 0.37%(27/7 248). Conclusions The incidence of acquired pressure ulcer in ClassⅢGrade A hospitals in our province is slightly higher than other domestic investigation results. The reasons may be that anti-pressure devices in hospital configuration are not enough, lack of the tailored bundle of prevention measures of pressure ulcer, and failure to establish an effective early warning management model on pressure ulcer etc. So prevention and treatment of pressure ulcer should have a further standard management. Instrument related pressure ulcer and incontinence related dermatitis should also attract the attention of clinical nurses and managers.

Using cell membrane chromatography and HPLC-TOF/MS method for in vivo study of active components from roots of Aconitum carmichaeli / 药物分析学报

An offline two-dimensional system combining a rat cardiac mascle cell membrane chromatography time-of-flight mass spectrometry （CMC-TOF/MS） with a high performance liquid chromatography time-of-flight mass spectrometry （HPLC-TOF/MS） was established for investigating the parent components and metabolites in rat urine samples after administration of the roots of Aconitum carmichaeli. On the basis of the analysis of the first dimension, retention components of the urine sample were collected into 30 fractions （one fraction per minute）. Then offline analysis of the second dimension was carried out. 34 compounds including 24 parent alkaloids and 10 potential metabolites were identified from the dosed rat urine, and then binding affinities of different compounds on cell membranes were compared and influences of some functional groups on activity were estimated with the semi-quantification and curve fitting method. As a result, binding affinities decreased along with the process of deacylation, debenzoylation and demethylation, which may be related to the alleviation of toxicity in the procedure of herb processing or metabolism. Moreover, some minor components in rat urine （Songorine, 14-benzoylneoline, Deoxyaconitine, etc. ） exerted relatively strong affinity on cell membranes are worth exploring. The results delivered by the system suggest that the CMC can be applied to in vivo study.
