The prevalence rate of heart failure is increasing year by year,posing a significant threat to human health,partly due to the rapid growth of overweight and obese populations.Obesity,as an independent risk factor of heart failure,affects hemodynamics,cardiac structure and cardiac function through mechanisms such as adipocyte release of adipokines,insulin resistance and accumulation of epicardial adipose tissue.Although the results of whether weight loss can reduce heart failure incidence are inconsistent,weight loss is associated with benefits such as reduced symptoms and comorbidities,and improved quality of life.Weight loss thus plays an indispensable role in the prevention and management of cardiovascular diseases in obese individuals.Currently,effective weight loss strategies confirmed by evidence-based studies mainly include lifestyle interventions,medication therapy and weight loss surgery.

OBJECTIVE To investigate the efficacy of Methotrexate （MTX） injection combined with Mifepristone tablets in the treatment of ectopic pregnancy. METHODS A retrospective cohort study method was used to collect data on patients with ectopic pregnancy who visited the Affiliated Hospital of Chengdu University from January 1， 2013 to December 31， 2021. Control group was given MTX injection alone， and exposure group was given MTX injection combined with Mifepristone tablets. Baseline variables were balanced between the two groups using a propensity score matching （PSM）， and the outcomes of the matched cohorts were compared. RESULTS A total of 125 patients were included， involving 68 in the control group and 57 in the exposure group. After PSM， 46 cases in each group were successfully matched. There was no significant difference in the treatment response rate and the incidence of adverse drug reaction （ADR） between the exposure group and the control group， which were 73.91% and 63.04%， 21.74% and 13.04% （P＞0.05）. Compared with before treatment， serum levels of β-HCG were all significantly decreased in 2 groups after treatment （P＜0.05）； there was no significant difference in the serum level of β-HCG after treatment， the time to return to normal， the interval time of second pregnancy， second ectopic pregnancy and second intrauterine pregnancy between 2 groups （P＞0.05）. The mean diameter difference of B-ultrasound pregnancy mass before and after treatment， duration of clinical symptom remission and length of hospital stay in the exposure group were significantly higher than those in the control group （P＜ 0.05）， but drug costs during hospitalization and total hospitalization costs were not significantly increased （P＞0.05）. There were no significant difference between single-dose group and multi-dose group of MTX in the treatment response rate and the incidence of ADR （P＞0.05）. The hospitalization time， drug cost and total cost of the single dose group were significantly less than those of the multi-dose group （P＜0.05）. CONCLUSIONS MTX injection combined with or without Mifepristone tablet can both effectively treat ectopic pregnancy， with comparable efficacy and safety. MTX single-dose regimen is similar to the multi-dose regimen in efficacy， but the multi-dose regimen increases the hospital stay and hospitalization costs.

Thyroid disease is characterized by unusual levels of thyroid hormones, which results in either hyperthyroidism or hypothyroidism. The pathology of a particular type or stage of thyroid disease is very complicated, and always linked to a variety of biological functions. Although the mortality rate is not high, thyroid dysfunction could lead to metabolic and immunological disorders that can subsequently cause discomfort. To date, many drugs are suggested to have curative effects on thyroid disease, however, drug toxicity and long treatment periods encourage the search for more promising ones. Prunella vulgaris L. (Labiatae) is a popular herb that has shown great potential for improving human immunity and organ protection. It has been extensively used in the treatment of many diseases but its ability to treat specific diseases has not been fully reported. In this review, a literature search regarding herbs and herbal recipes for treating thyroid disease were carried out, organized, and summarized. In addition, this study conducted a literature search on the current situation and progress of P. vulgaris treatment for various diseases. Finally, this study discussed studies regarding P. vulgaris treatment of goiter, and the mechanism of treatment through the regulation of apoptosis. Accordingly, a combination therapy of herbs and Western medicine can provide significant therapeutic effects in the clinical treatment of thyroid disease. Furthermore, the association between P. vulgaris and various diseases suggests that P. vulgaris is rich in a variety of active substances that can fight oxidation and participate in the regulation of apoptosis, thus having a protective effect on the thyroid. Here, a comprehensive literature review regarding the application of herbs or herbal recipes in the treatment of thyroid disease was presented. It is concluded that there is strong evidence for further research regarding the use of P. vulgaris in the treatment of thyroid diseases.

The measurement data conforming to normal distribution was expressed in xˉ± s.The non normal distribution data was expressed in M (Q1, Q3). Wilcoxon rank sum test was used to compare the difference between the two groups. Results:There was significant difference between RMS (30.0 (21.3, 45.5) μV vs. 24.0 (14.0, 35.8) μV) and IEMG (15.5. (10.0, 23.0) μV?s vs. 9.0 (5.0, 13.0) μV?s s) values of gluteus maximus on the healthy side and the affected side during double bridge exercise ( Z values were 2.07, 4.19; P values were 0.039, <0.001, respectively). There was significant difference in RMS (31.0 (15.3, 70.0) μV ratio of the healthy and affected biceps femoris 17.0 (11.0, 28.8) μV) and IEMG (14.5 (8.0, 26.5) μV?s vs. 7.0 (5.0, 10.8) μV?s) values of biceps femoris on the healthy side during double bridge exercise ( Z values were 3.44, 3.64; P values were 0.001 and <0.001, respectively ). There was significant difference between RMS(38.5(32.3, 46.0) μV vs. 35.0(22.3, 43.0) μV) and IEMG (16.5(12.0, 22.8) μV?s vs. 12.0(7.0, 21.0) μV?s) values of the gluteus maximus on the healthy side during single bridge exercise ( Z values were 2.24, 2.45; P values were 0.025, 0.014, respectively). There was significant difference between RMS (38.0 (15.3, 70.0) μV vs. 19.0 (12.0, 35.5) μV) and IEMG (16.0 (10.0, 27.0) μV?s vs. 6.5 (5.0, 12.5) μV?s s) values of biceps femoris on the healthy side during single bridge exercise ( Z values were 2.98,4.34; P values were 0.003 and <0.001, respectively). There was significant difference between RMS (24.0 (14.0, 35.8) μV vs. 35.0 (22.3, 43.0) μV) and IEMG (9.0 (5.0, 13.0) μV?s vs. 12.0 (7.0, 21.0) μV?s) values of double and single gluteus maximus on the affected side ( Z values were 2.24, 1.99; P values were 0.025,0.047, respectively). Conclusion:Double bridge and single bridge exercise could improve the related core muscle groups of stroke patients with hemiplegia, and single bridge was better than double bridge for the activation of gluteus maximus

Objective:To analyze the material basis, target and pathway of Chebulae fructus and Margarita in Mongolian medicine Garidi-13 Pill on stroke with the method of network pharmacology and molecular docking technology, so as to better understand its "detoxification" mechanism. Methods:TCMIP and BATMAN-TCM were used to predict the target of Chebulae fructus and Margarita composition, and GeneCards were used to search for the target of stroke. The overlapping targets of the two platforms were imported into the Metascape software for GO biological analysis and KEGG pathway analysis. The molecular docking of key molecules and targets was carried out with LEDOCK. Results:A total of 22 active components were collected and 217 targets related to stroke were predicted. Among them, 1-O-galloyl-glucose, cuprum, ellagicacid, arjungenin and corilagin were the key substances playing the role of "detoxification" of the Chebulae fructus and Margarita; IL6, TNF, HSP90AA1, PTGS2, CASP3, NR1I2, VKORC1 and ATP1A1 were the key targets playing the role of "detoxification" . These targets were significantly enriched in cell response, humoral level regulation, hemostasis, response to steroid hormones, steroid metabolism, coagulation and other biological processes, as well as nitrogen metabolism, IL-17 signaling pathway and other pathways. Molecular docking verified the accuracy of previous prediction results from computer simulation level. Conclusion:The process of Chebulae fructus and Margarita intervening strok is closely related to the elimination of harmful metabolites and calmingthe inflammatory reaction, which was not only consistent with the modern medicine on the pathological process of stroke, but also consistent with the interpretation of "evil and poison" with Mongolian medicine theory.
