Different processed products of Coptidis Rhizoma have its unique odor, which is an important assessment index for pro- cessed products identification of Coptidis Rhizoma. Objectify odor as an entry point in this study, an electronic nose technology was used, and a suitable method for Coptidis Rhizoma measurement was built firstly. Then different processed products of Coptidis Rhizoma were detected by the method built. Finally, different processed products were identified by combining with chemometrics based on the objective odor information obtained. Electronic nose detection indicated that a significant difference in odor between different processed products was performed. Coptidis Rhizoma processed or not can be distinguished based on statistical quality control (SQC) and soft independent modeling of class analogy (SIMCA). Principle component analysis (PCA) model showed that Coptidis Rhizoma and its various processed products discriminated obviously. In addition, in order to identify the processed products of Coptidis Rhizoma, a correct recognition rate of 100% was acquired by discriminant factor analysis (DFA) , and the initial identification rate and cross-validation recognition rate of linear discriminant analysis (LDA) is 100%, 94.4% respectively. In conclusion, differentiationin odor of different processed Coptidis Rhizoma was performed by the electronic nose technology used, and different products Coptidis Rhizoma were dis- criminated by combining with chemometrics. This research can be a reference for objective identification in odor of traditional Chinese medicine, and is good for the inheritance and development of traditional experience in odor identification.

OBJECTIVES: Falls is a risk factor for fracture. The FRAX® predicts fractures. Whether the FRAX® is associated with fall in both gender is inconclusive. The aim of our study is to evaluate the association between FRAX scores and falls. METHODS: The cross-sectional study set from 2009 to 2010 included 1200 community-dwelling people who were systematically sampled in central Taiwan. The 1200 participants (men: 524; women: 676; ≥40 years old) completed questionnaires about socioeconomic status; lifestyle; medical and fall history were completed. FRAX scores with and without bone mineral density (BMD) were calculated by using the Taiwan calculator. RESULTS: A total of 19.8% participants fell down. Binary regression models showed that diabetes mellitus history (OR: 1.61; 95% CI: 1.03–2.52), the FRAX without BMD in a continuous major score (OR: 1.06; 95% CI: 1.03–1.09), continuous hip score (OR: 1.11; 95% CI: 1.05–1.16), categorical major score ≥ 10% (OR: 1.81; 95% CI: 1.25–2.61), and categorical hip score ≥ 3% (OR: 1.80; 95% CI: 1.30–2.50) were independent risk factors for falls. FRAX with BMD in a continuous major score (OR: 1.04; 95% CI: 1.02–1.06), continuous hip score (OR: 1.06; 95% CI: 1.02–1.09), categorical major score ≥ 10% (OR: 1.52; 95% CI: 1.09–2.12), and categorical hip score ≥ 3% (OR: 1.53; 95% CI: 1.13–2.09) were also independent risk factors. CONCLUSIONS: We concluded that FRAX® scores with and without BMD were unanimously correlated with falls in community-dwelling middle-aged and elderly males and females.

Objective:To introduce a phased evaluation for severe traumatic brain injury in clinical nursing, to promote catheter removal planning. Methods:A case of severe traumatic brain injury in our hospital in October, 2018 was reviewed. Results:This case accepted a phased evaluation about consciousness, condition of tracheotomy and extubation, bladder safety capacity and residual urine volume, and the rehabilitation nursing targeted to the results. After 54 days of treatment and care, all the catheters were removed in a planned way. Conclusion:The phased evaluation for severe traumatic brain injury may promote the planning of catheter removal, prevent repeated tube placement, and facilitate the recovery of patients.
