Heterogeneous graph construction and node representation learning method of Treatise on Febrile Diseases based on graph convolutional network / 数字中医药（英文）

Objective@#To construct symptom-formula-herb heterogeneous graphs structured Treatise on Febrile Diseases (Shang Han Lun,《伤寒论》) dataset and explore an optimal learning method represented with node attributes based on graph convolutional network (GCN).@*Methods@#Clauses that contain symptoms, formulas, and herbs were abstracted from Treatise on Febrile Diseases to construct symptom-formula-herb heterogeneous graphs, which were used to propose a node representation learning method based on GCN − the Traditional Chinese Medicine Graph Convolution Network (TCM-GCN). The symptom-formula, symptom-herb, and formula-herb heterogeneous graphs were processed with the TCM-GCN to realize high-order propagating message passing and neighbor aggregation to obtain new node representation attributes, and thus acquiring the nodes’ sum-aggregations of symptoms, formulas, and herbs to lay a foundation for the downstream tasks of the prediction models.@*Results@#Comparisons among the node representations with multi-hot encoding, non-fusion encoding, and fusion encoding showed that the Precision@10, Recall@10, and F1-score@10 of the fusion encoding were 9.77%, 6.65%, and 8.30%, respectively, higher than those of the non-fusion encoding in the prediction studies of the model.@*Conclusion@#Node representations by fusion encoding achieved comparatively ideal results, indicating the TCM-GCN is effective in realizing node-level representations of heterogeneous graph structured Treatise on Febrile Diseases dataset and is able to elevate the performance of the downstream tasks of the diagnosis model.

Effect of cognitive-behavioral therapy on psychological stress and quality of life in patients with pulmonary tuberculosis / 中华全科医师杂志

Objective:To explore the effect of cognitive-behavioral therapy on psychological stress and quality of life in patients with pulmonary tuberculosis.Methods:According to two-level cluster random design 461 patients with tuberculosis from 20 communities in Pizhou county of Jiangsu province were selected in the study from September 2018 to November 2018. The intervention group received cognitive-behavioral therapy for two months, while control group received routine follow-up. Anxiety, depression and quality of life were assessed by GAD-7, PHQ-9 and SF-36 scales, respectively. At the same time, the comparison between the two groups was conducted by independent sample t test, and the difference between the two groups before and after treatment was analyzed by paired sample ttest. Results:A total of 454 participants were finally included in this analysis; there were 230 cases in the intervention group and 224 cases in the control group. In the intervention group the scores of anxiety and depression after intervention were significantly lower than the baseline scores [(7.57±5.27) vs. (5.93±2.56), t=-4.245, P<0.01; (8.13±6.01) vs. (6.02±2.67); t=-4.866, P<0.01], and the quality of life score was significantly higher than the baseline score [(58.46±12.71) vs. (74.31±13.22); t=13.108, P<0.01]; while in the control group there were no significant differences in the scores of anxiety, depression and quality of life after intervention, compared with those at baseline [(7.62±5.41) vs.(7.65±5.38); (8.00±5.84) vs. (8.07±5.91); (59.11±13.25) vs. (60.51±13.76); t=0.059, t=0.126, t=1.104, all P>0.05]. However, only for patients with mild and moderate anxiety and depression symptoms in the intervention group, the anxiety and depression scores were decreased after intervention [(7.29±1.21) vs. (5.54±1.71), (11.99±1.31) vs. (9.17±1.55); (7.01±1.47) vs. (4.42±1.22), (11.88±1.12) vs. (8.39±2.33); t=8.056, t=10.020, t=13.558, t=8.852,all P<0.01]. Conclusion:Cognitive-behavioral therapy can relieve the psychological pressure and improve the quality of life in pulmonary tuberculosis patients with mild or moderate anxiety/depression symptoms.

Analysis of risk factors for osteoporosis in patients with pemphigus treated with systemic glucocorticoids / 中华皮肤科杂志

Objective:To investigate the incidence of and risk factors for osteoporosis in patients with pemphigus treated with systemic glucocorticoids, and to analyze the current status of prevention and treatment of osteoporosis.Methods:Clinical data were collected from 101 inpatients with pemphigus treated in Institute of Dermatology, Chinese Academy of Medical Sciences and Peking Union Medical College from January 2014 to January 2019, and these patients were divided into osteoporosis group ( n= 21) and non-osteoporosis group ( n= 80) according to their bone mineral density (BMD) values. Correlations of osteoporosis with patients′ general information, treatment duration and cumulative dose of glucocorticoids, application of immunosuppressive agents, diabetes mellitus, hypertension, hyperlipidemia, smoking, outdoor activity and other factors were analyzed, and the application status of calcium supplements, vitamin D and bisphosphonates was also analyzed. Enumeration data were compared by using chi-square test, measurement data were compared by using t test, and multiple factors influencing osteoporosis were analyzed by using non-conditional Logistic regression analysis. Results:Logistic regression analysis showed that age ( P= 0.001, OR= 1.08, 95% CI: 1.03- 1.14) and cumulative dose of glucocorticoids ( P<0.001, OR= 1.72, 95% CI: 1.18- 2.52) were risk factors for the occurrence of osteoporosis, while outdoor activity ( P<0.001, OR= 0.04, 95% CI: 0.01- 0.21) was a protective factor. Moreover, 13 (61.9%) patients in the osteoporosis group and 16 (21.6%) patients in the non-osteoporosis group received combination treatment with calcium supplements, vitamin D and bisphosphonates. Conclusions:Pemphigus patients treated with systemic glucocorticoids are prone to develop osteoporosis. Older age, cumulative dose of glucocorticoids may be risk factors for osteoporosis in patients with pemphigus, while outdoor activity may be a protective factor. The prevention and treatment of osteoporosis in pemphigus patients are still not standardized.
