Under the background of the medical model shifting from biomedicine to systems medicine， the traditional Chinese medicine （TCM） concept of "treating different diseases in the same way" demonstrates unique scientific value. From the perspective of systems biology， this study proposes that "treating different diseases in the same way" is essentially "treating the disease with same mechanism in the same way"； that is， different diseases share common pathological links at levels such as neuro-endocrine-immune network homeostasis， inflammatory signaling pathways， or gut microecology. Through the application of the "same formulas" and "same medicinals"， TCM intervenes in these shared network nodes. On this basis， the modern medical value of the "treating different diseases in the same way" concept is elucidated from three dimensions including "network causality" in epistemology， "systemic modulation" in methodology， and "comorbidity management" in practice. It reveals that as a life network regulation concept based on holism， "treating different diseases in the same way" provides novel diagnostic and therapeutic strategies for complex chronic diseases and multimorbidity.

OBJECTIVE To explore the safety， effectiveness， and cost-effectiveness of elderly patients with sarcopenia receiving Shenling baizhu powder combined with nutrition and exercise intervention， providing a reference for rational clinical drug use. METHODS A total of 237 elderly sarcopenia patients were randomly assigned to an observation group （118 cases） and a control group （119 cases）. Both groups of patients received nutrition and exercise intervention； the observation group added Shenling baizhu powder （6 g each time， three times daily） on this basis. The safety， effectiveness， and cost-effectiveness of the two plans were compared after 3 months. RESULTS Both groups of patients completed the follow-up. Before intervention， no significant difference was observed in skeletal muscle index （SMI）， grip strength， and 6-minute walk test （6MWT） speed between the two groups （P＞0.05）. After intervention， the grip strength of the patients in the observation group was significantly greater than that of the control group （25.05 kg vs. 23.18 kg， P＜0.01）； the treatment response rate of sarcopenia， SMI， and 6MWT speed were higher than those of the control group， butthe differences were not statistically significant （P＞0.05）. The adverse reaction/event rate of the patients in the observation group was lower than that of the control group （14.41% vs. 16.81%， P＝0.611）， but the difference was not statistically significant. Compared with the control group’s plan， the cost of the observation group’s plan was higher （981.25 yuan vs. 913.94 yuan）， and the effect was better （effectiveness rate： 0.618 6 vs. 0.563 0）， with an incremental cost-effectiveness ratio of 1 210.61 yuan. The results of the sensitivity analysis were consistent with the cost-effectiveness analysis results. CONCLUSION Elderly patients with sarcopenia who receive Shenling baizhu powder combined with nutrition and exercise intervention can significantly strengthen grip strength without increasing the incidence of adverse reactions/events. Compared with the control group plan， the observation group needs to spend an additional 1 210.61 yuan for each additional effective patient with sarcopenia.

OBJECTIVE To screen the prescription and preparation method of Bupleurum nanoemulsion, and evaluate its quality, study the antipyretic effect. METHODS The emulsifier and co-emulsifier of the nanoemulsion were preliminarily screened, and then the prescription was screened by pseudo-ternary phase diagram.

【Objective】 To compare the value of CT pulmonary angiography (CTPA) and echocardiography in predicting the degree pulmonary hypertension (PH). 【Methods】 Fifty-four patients in our hospital who underwent right heart catheterization, CTPA and echocardiography for suspected or confirmed PH from November 2013 to April 2021 were retrospectively recruited. Pulmonary artery systolic pressure (PASP) and mean pulmonary artery pressure (PAMP) were measured by right heart catheterization. According to PAMP, the patients were divided into non-PH group and mild, moderate, and severe PH groups. The three-dimensional model of the pulmonary artery was obtained by computer-aided segmentation, and the best fitting circle diameter (Dfit), inscribed circle diameter (Dmin), circumscribed circle diameter (Dmax), hydraulic diameter (Dh), cross-sectional area (Area), circumference (Scf), and the largest area and largest short diameter of the right ventricle were measured. Echocardiography was used to estimate PASP. The differences in the above parameters between different PH groups were compared, the correlations of the above parameters with PASP and PAMP were analyzed, and statistically significant indicators were included to establish three predictive models of PAMP (Model 1: CTPA pulmonary artery; Model 2: CTPA pulmonary artery+CTPA right ventricle; Model 3: CTPA pulmonary artery+CTPA right ventricle+echocardiography), and receiver operating characteristic (ROC) curves were used to compare the diagnostic performance of the three models. 【Results】 Some parameters of main pulmonary artery (Dfit, Dmin, Dmax, Dh, Area, Scf), right pulmonary artery (Dmax, Dh, Area, Scf), left pulmonary artery (Dfit), and right ventricular short diameter increased with the increase of PAMP (P<0.05). Dfit, Dmin, Dh, and area of main pulmonary artery, right pulmonary artery and left pulmonary artery were positively correlated with PASP and PAMP (P<0.05). Right ventricular short diameter and right ventricular maximum area were positively correlated with PASP (P<0.05), and right ventricular short diameter was positively correlated with PAMP (P<0.05). The estimated value of pulmonary artery systolic blood pressure in echocardiography was positively correlated with PASP and PAMP (P<0.05). Model 1, Model 2 and Model 3 could all be used to identify mild PH and moderate PH, among which Model 3 had the best performance in identifying non-PH and mild PH, moderate PH and severe PH. 【Conclusion】 CTPA and echocardiography are helpful in assessing the degree of PH, and the combination of the two has better accuracy in distinguishing non-PH from mild PH, moderate and severe PH.
