ABSTRACT
Objective:To analyze the characteristics of prescription about Lingnan Traditional Chinese Medicine (TCM) masters for Biqiu treatment based on data mining, so as to provide reference for the clinical practice and patent drug research and development of rhinorrhea in Lingnan district.Methods:By searching journal documents and medical records in CNKI, VIP, Wanfang, Chinese BioMedical Database (SinoMed) and Duxiu Data Retrieval Platform, we selected the articles and famous TCM medical records that met the criteria on the TCM medical rules of treating Biqiu. We screened database in strict accordance with inclusion and exclusion criteria and extracted prescription information from medical cases. The software Ancient and Modern Consilia Cloud Platform (V 1.5) was used for data mining analysis and medical case standardization, and SPSS Clementine 12.0 software were used to conduct frequency statistics, association analysis and cluster analysis of drugs in medical cases. Results:A total of 31 articles and 42 medical cases including 73 prescriptions were screened. The frequency results showed that there were 40 kinds of high frequency TCMs (frequency more than 5), mainly including drugs for benefiting the qi and strengthening the spleen, medicine to relieve cold and promote nasal passages, which was the same as the frequency statistics of the effects of herbal medicine. Seven drug groups were obtained by cluster analysis. The results of rule analysis showed that 16 association rules for drug pairs and 18 association rules for 3 TCMs pairs were obtained.Conclusions:While treating allergic rhinitis, Lingnan medical doctors focus on tonifying spleen qi, dispersing wind and cold, and promoting the nasal passages, which reflect the treatment theory of cultivating earth and generating gold, and attacking and tonifying. Lingnan medical doctors commonly used Guangdong medicinal herbs, which have distinct regional characteristics. The data mining methods can comprehensively summarize and explore the potential rules of Lingnan prominent practitioners' treatment of allergic rhinitis, and provide reference for guiding the treatment of congested nose and congested nose in TCM.
ABSTRACT
Objective To compare differences in mechanical stability of intramedullary fibular allograft with cannulated screw (modified method) and cannulated screw alone (conventional method) for fixing young and middle-aged Pauwels Ⅰ, Ⅱ, Ⅲ femoral neck fractures. Methods Models of Pauwels Ⅰ, Ⅱ, Ⅲ femoral neck fracture fixed by conventional method and modified method were constructed. Stress distributions on weight-bearing area of the femoral cortical bone shell and the end of femoral neck fracture, as well as shear stress distributions on cortical bone shell of the femoral head and femoral neck fracture surface were analyzed, the maximum principal strain cloud maps of the femur in coronal position were drawn according to the predicted data, and the displacements of femoral neck fracture end between two groups were compared. Results The shear stress distributions on cortical bone shell of the femoral head in two directions (S12, S13) showed that femoral neck fractures fixed by modified method was superior or close to that by conventional method. Besides, the shear stress distributions on fracture surface of the femoral neck in two directions (S12, S23) showed that modified internal fixation was superior to conventional internal fixation. The displacements of femoral neck fracture end in Pauwels Ⅱ and Ⅲ fracture fixed by conventional method were greater than those by modified method and the displacements of Pauwels Ⅱ fracture fixed by conventional method were obviously larger than those of Pauwels Ⅱ fracture fixed by modified method. But Pauwels Ⅰ fracture fixed by modified method showed a larger displacement than that fixed by conventional method. Conclusions Modified method is more suitable for fixing femoral neck fracture with large angles (Pauwels Ⅱ and Ⅲ fracture), and conventional method is more suitable for fixing neck fracture with small angles (Pauwels Ⅰ fracture).
ABSTRACT
OBJECTIVE:To provide idea and reference for TCM therapy for hemoptysis. METHODS:The prescriptions for hemoptysis included in TCM Prescription Dictionary were screened,summarized and logged in TCM inheritance support platform software(V2.5). The medication frequency was analyzed statistically. Apriori algorithm was used to analyze combination of medicinal materials(the number of support degree was 12)and its association rules(confidence degree>0.7)statistically. Correlation coefficient of 2 different medicinal materials(related coefficient of 8,penalty coefficient of 2)and core combination of 3 and 4 ingredients were analyzed statistically by complex system entropy clustering method. Core combination and new prescription were extracted by unsupervised entropy hierarchical clustering method. RESULTS:Totally 105 prescriptions for hemoptysis were screened and included 198 ingredients,among which 39 ingredients were used more than 6 times;there were 30 common couplet medicines(including 15 ingredients)and 11 correlation regularities;48 core combination of 3 ingredients and 5 core combination of 4 ingredients were obtained. Each 6 core combination 1 and 2 were extracted for new prescription clustering to obtain 6 new prescriptions. CONCLUSIONS:The efficacy of each ingredient of the prescriptions for hemoptysis mainly include clearing heat and cooling blood,nourishing Qi and blood,eliminating phlegm and relieving cough. The efficacy of couplet medicines for hemoptysis mainly include clearing heat and cooling blood combined with nourishing Yin and blood,tonifying Qi and Yin. The composition of new prescription shows diverse characteristics,and pay attention to cooling blood to stop bleeding, nourishing Qi and nourishing Yin,or clearing heat and eliminating phlegm.
