RÉSUMÉ

A complete proteomics study characterizing active androgen receptor (AR) complexes in prostate cancer (PCa) cells identified a diversity of protein interactors with tumorigenic annotations, including known RNA splicing factors. Thus, we chose to further investigate the functional role of AR-mediated alternative RNA splicing in PCa disease progression. We selected two AR-interacting RNA splicing factors, Src associated in mitosis of 68 kDa (SAM68) and DEAD (Asp-Glu-Ala-Asp) box helicase 5 (DDX5) to examine their associative roles in AR-dependent alternative RNA splicing. To assess the true physiological role of AR in alternative RNA splicing, we assessed splicing profiles of LNCaP PCa cells using exon microarrays and correlated the results to PCa clinical datasets. As a result, we were able to highlight alternative splicing events of clinical significance. Initial use of exon-mini gene cassettes illustrated hormone-dependent AR-mediated exon-inclusion splicing events with SAM68 or exon-exclusion splicing events with DDX5 overexpression. The physiological significance in PCa was investigated through the application of clinical exon array analysis, where we identified exon-gene sets that were able to delineate aggressive disease progression profiles and predict patient disease-free outcomes independently of pathological clinical criteria. Using a clinical dataset with patients categorized as prostate cancer-specific death (PCSD), these exon gene sets further identified a select group of patients with extremely poor disease-free outcomes. Overall, these results strongly suggest a nonclassical role of AR in mediating robust alternative RNA splicing in PCa. Moreover, AR-mediated alternative spicing contributes to aggressive PCa progression, where we identified a new subtype of lethal PCa defined by AR-dependent alternative splicing.

RÉSUMÉ

Since 2016, a number of studies have been published on standard decoctions used in Chinese medicine. However, there is little research on statistical issues related to establishing the quality standards for standard decoctions. In view of the currently established quality standard methods for standard decoctions, an improvement scheme is proposed from a statistical perspective. This review explores the requirements for dry matter yield rate data and index component transfer data for the application of two methods specified in “Technical Requirements for Quality Control and Standard Establishment of Chinese Medicine Formula Granules,” which include the average value plus or minus three times the standard deviation (X-±3SD) or 70% to 130% of the average value (X-±30%X-). The square-root arcsine transformation method is used as an approach to solve the problem of unreasonable standard ranges of standard decoctions. This review also proposes the use of merged data to establish a standard. A method to judge whether multiple sets of standard decoction data can be merged is also provided. When multiple sets of data have a similar central tendency and a similar discrete tendency, they can be merged to establish a more reliable quality standard. Assuming that the dry matter yield rate and transfer rate conform to a binomial distribution, the number of batches of prepared slices that are needed to establish the standard decoction quality standard is estimated. It is recommended that no less than 30 batches of prepared slices should be used for the establishment of standard decoction quality standards.

RÉSUMÉ

BACKGROUND: Human leukocyte antigen (HLA) typing is important for transplant patients to prevent a severe mismatch reaction, and the result can also support the diagnosis of various disease or prediction of drug side effects. However, such secondary applications of HLA typing results are limited because they are typically provided in free-text format or PDFs on electronic medical records. We here propose a method to convert HLA genotype information stored in an unstructured format into a reusable structured format by extracting serotype/allele information.METHODS: We queried HLA typing reports from the clinical data warehouse of Seoul National University Hospital (SUPPREME) from 2000 to 2018 as a rule-development data set (64,024 reports) and from the most recent year (6,181 reports) as a test set. We used a rule-based natural language approach using a Python regex function to extract the 1) number of patients in the report, 2) clinical characteristics such as indication of the HLA testing, and 3) precise HLA genotypes. The performance of the rules and codes was evaluated by comparison between the extracted results from the test set and a validation set generated by manual curation.RESULTS: Among 11,287 reports for development set and 1,107 for the test set describing HLA typing for a single patient, iterative rule generation developed 124 extracting rules and 8 cleaning rules for HLA genotypes. Application of these rules extracted HLA genotypes with 0.892–0.999 precision and 0.795–0.998 recall for the five HLA genes. The precision and recall of the extracting rules for the number of patients in a report were 0.997 and 0.994 and those for the clinical variable extraction were 0.997 and 0.992, respectively. All extracted HLA alleles and serotypes were transformed according to formal HLA nomenclature by the cleaning rules.CONCLUSION: The rule-based HLA genotype extraction method shows reliable accuracy. We believe that there are significant number of patients who takes profit when this under-used genetic information will be return to them.

RÉSUMÉ

Background@#Summative assessment of student performance should provide information on achievement of program outcomes to support evaluation decisions. Alternative approaches to the traditional assessment systems like the written licensure examinations in Physical Therapy (PT) should be explored to ensure valid measurement of achievement of these terminal outcomes. @*Objective@#The study aimed at establishing equivalence of two summative assessments new to PT in measuring achievement of the PT outcomes: work-based assessment using Entrustable Professional Activities (EPA) and knowledge-based assessment using Context-Dependent Item Sets (CDIS). @*Methodology@#Thirty-two newly graduated PT's underwent a one-week EPA assessment and took a 102-item CDIS test (based on 14 clinical vignettes). Qualitative data from blueprint review, group face-to-face interviews with participants and assessors, and field notes from observations, and quantitative data from EPA entrustment decisions and CDIS scores were utilized to ascertain their comparability in terms of Purpose, Administration, Quality and Decisions. This was used to determine the extent of equivalence of the two assessments. @*Results@#Review of both blueprints show alignment with PT outcomes, with integrative content motivating participants towards professional development. Administration were equally acceptable to users, though EPA had more practice opportunities with a longer assessment time. Entrustment decisions in EPA had a high inter-rater reliability, while CDIS had low reliability, with most items having poor discriminative power. Decisions of “pass” or “fail” had good concordance when high prevalence indices were considered. @*Conclusion@#There is high extent of equivalence in purpose of EPA and CDIS but are not equivalent in terms of administration. There is moderate equivalence in quality and decisions, with potential for increased concordance if improved quality of CDIS is attained.

RÉSUMÉ

OBJECTIVE: To establish a comprehensive and multi-angle evaluation model for rational drug use in medical institutions, and to provide support for rational drug use in medical institutions. METHODS: Referring to the phenomenon of irrational drug use and its influential factors in medical institutions, rational drug use evaluation indicator system, which contained 3 evaluation subjects, 6 first-level indicators and 15 second-level indicators, was established on the basis of 360-degree Feedback Method, with hospitals at the same level, superior regulation department and patient as subjects of multi-angle evaluation. At the same time, the linguistic information of vague and uncertain evaluation given by the evaluation subject was comprehensively quantified by Hesitant Fuzzy Sets Theory. The total evaluation score of rational drug use in the evaluated medical institutions was calculated by using the score function formula of hesitant fuzzy number; the level of rational drug use in medical institutions was determined according to the score (the higher the total score, the higher the comprehensive level of rational drug use). RESULTS: An all-round and multi-angle evaluation model of rational drug use in medical institutions was established. According to the evaluation index system based on 360-degree feedback evaluation method, the evaluation subject and weight of evaluation index were determined, the grade of evaluation index was divided, the hesitant fuzzy numbers of each index were gathered, and the first-level index was weighted. Finally, the total evaluation score of rational drug use in medical institutions was calculated; the examples were set to prove the feasibility of the model. CONCLUSIONS: The established evaluation model for rational drug use in medical institutions based on 360-degree Feedback Method and Hesitant Fuzzy Sets Theory can comprehensively and effectively evaluate the rational drug use in medical institutions, and contribute to standardizing and improving clinical drug use behavior in medical institutions.

RÉSUMÉ

Analyzing patterns in data points embedded in linear and non-linear feature spaces is considered as one of the common research problems among different research areas, for example: data mining, machine learning, pattern recognition, and multivariate analysis. In this paper, data points are heterogeneous sets of biosequences (composite data points). A composite data point is a set of ordinary data points (e.g., set of feature vectors). We theoretically extend the derivation of the largest generalized eigenvalue-based distance metric D(ij)(γ₁) in any linear and non-linear feature spaces. We prove that D(ij)(γ₁) is a metric under any linear and non-linear feature transformation function. We show the sufficiency and efficiency of using the decision rule δ(Ξi) (i.e., mean of D(ij)(γ₁)) in classification of heterogeneous sets of biosequences compared with the decision rules min(Ξi) and median(Ξi). We analyze the impact of linear and non-linear transformation functions on classifying/clustering collections of heterogeneous sets of biosequences. The impact of the length of a sequence in a heterogeneous sequence-set generated by simulation on the classification and clustering results in linear and non-linear feature spaces is empirically shown in this paper. We propose a new concept: the limiting dispersion map of the existing clusters in heterogeneous sets of biosequences embedded in linear and nonlinear feature spaces, which is based on the limiting distribution of nucleotide compositions estimated from real data sets. Finally, the empirical conclusions and the scientific evidences are deduced from the experiments to support the theoretical side stated in this paper.

RÉSUMÉ

In this article, we have used an index, called Gaussian fuzzy index (GFI), recently developed by the authors, based on the notion of fuzzy set theory, for validating the clusters obtained by a clustering algorithm applied on cancer gene expression data. GFI is then used for the identification of genes that have altered quite significantly from normal state to carcinogenic state with respect to their mRNA expression patterns. The effectiveness of the methodology has been demonstrated on three gene expression cancer datasets dealing with human lung, colon and leukemia. The performance of GFI is compared with 19 exiting cluster validity indices. The results are appropriately validated biologically and statistically. In this context, we have used biochemical pathways, p-value statistics of GO attributes, t-test and zscore for the validation of the results. It has been reported that GFI is capable of identifying high-quality enriched clusters of genes, and thereby is able to select more cancer-mediating genes.

RÉSUMÉ

Rough set theory is a powerful tool to deal with incomplete information system, which can be applied to prescription data analysis. In this paper, we suggested an improved rough set model called WVP-T model. The model combined the variable precision model with the tolerance relation model. It can overcome the shortcoming of classical model. Furthermore, attribute importance and entropy of information were combined as heuristic information. Medicine was mapped to rough set attribute in order to value its importance. Then, combined with curative effect, attribute reduction was used to investigate the relationship between prescription and medicine and the relationship between symptom and syndrome. The experimental results showed that algorithm proposed in this paper can be used in prescription data analysis and can accurately reveal the compatibility rules to guide the clinical medication.

RÉSUMÉ

OBJECTIVE: This study proposes a new approach that considers uncertainty in predicting and quantifying the presence and severity of diabetic peripheral neuropathy. METHODS: A rule-based fuzzy expert system was designed by four experts in diabetic neuropathy. The model variables were used to classify neuropathy in diabetic patients, defining it as mild, moderate, or severe. System performance was evaluated by means of the Kappa agreement measure, comparing the results of the model with those generated by the experts in an assessment of 50 patients. Accuracy was evaluated by an ROC curve analysis obtained based on 50 other cases; the results of those clinical assessments were considered to be the gold standard. RESULTS: According to the Kappa analysis, the model was in moderate agreement with expert opinions. The ROC analysis (evaluation of accuracy) determined an area under the curve equal to 0.91, demonstrating very good consistency in classifying patients with diabetic neuropathy. CONCLUSION: The model efficiently classified diabetic patients with different degrees of neuropathy severity. In addition, the model provides a way to quantify diabetic neuropathy severity and allows a more accurate patient condition assessment.
