Objective To retrieve the anticoagulation management related evidences in postoperative patients with heart valve operation to provide an evidence-based basis for medical professionals conducting the antithrombotic therapy in postoperative patients with heart valve operation.Methods The related evidences of anticoagulation management after heart valve surgery were retrieved from major databases and websites at home and abroad based on the"6S"evidence resource pyramid modeling system.The retrieval time was from January 1,2017 to February 29,2024.Two researchers trained by evidence-based care evaluated the quality of the literatures and extracted the relevant evidences meeting the criteria by combining with clinical situation.Results A total of 12 literatures were included,including 5 guidelines,4 clinical practices and 3 expert consen-sus.Thirty pieces of best evidences were summarized in eight aspects:contraindications,postoperative an-tithrombotic regimens,warfarin use method,vitamin K use precautions,daily life precautions,anticoagulation complications,long term perioperative anticoagulation bridging and complicating pregnancy.Conclusion The evidences summarized in this study could provide a reference for standardizing anticoagulation management in postoperative pa-tients with heart valve operation and for clinical healthcare workers in order to standardize the anticoagulation therapy after heart valve replacement and reduce the occurrence of anticoagulation-related complications.

Primary hyperparathyroidism (PHPT) is a disorder of calcium metabolism, which is characterized by elevated blood calcium and PTH urine calcium, which is easy to involve multiple systems. The disease is mainly caused by a benign adenoma of parathyroid tissue, a few of which are parathyroid hyperplasia or parathyroid adenocarcinoma. As awareness of physical examination increased, the proportion of asymptomatic PHPT patients gradually increased. The disease can be cured by surgical resection of the parathyroid gland, most of which is a real good prognosis, but a few of them are complex and difficult to diagnose and treat. At present, there continue to be many controversies about the diagnosis and treatment of PHPT.This article is a review of the progress in the diagnosis and treatment of PHPT.

Objective To investigate the interaction between traditional Chinese medicine syndromes of patients with chronic heart failure (CHF) and the primary pathogenesis of CHF, so as to grasp the distribution regularity of TCM syndrome caused by different primary diseases and provide reference for better intervention of CHF. Methods A total of 580 patients with CHF were included in the clinical cross-sectional study. The baseline data of the patients, the primary disease and the four diagnosis information of TCM were collected. The syndromes of TCM were judged and the logistic regression method was used to analyze the correlation of CHF and the distribution of syndromes. Results Analysis of TCM Syndromes of CHF showed that the main syndromes were Qi deficiency syndrome, blood stasis syndrome, water retention syndrome, yin deficiency syndrome, phlegm syndrome, and yang deficiency syndrome. Further analysis showed that the above causes of CHF were related to the distribution of TCM syndromes. When coronary heart disease is the primary disease, blood stasis syndrome, yang deficiency syndrome, and yin deficiency syndrome are related to the occurrence of CHF (χ2 values are 0.480, 4.445, 0.192, P<0.05). When hypertension is the primary disease, blood stasis syndrome and phlegm syndrome are related to the occurrence of CHF (χ2 values are 12.344, 10.990, P<0.05); dilated cardiomyopathy is the primary disease, blood stasis syndrome and yang deficiency syndrome and chronic heart failure It is related (χ2=5.222, 3.456, P<0.05). Conclusions The distribution patterns of TCM Syndromes of CHF caused by different primary diseases were different, which was related to the pathogenesis of CHF. It is of great significance for better application of traditional Chinese medicine CHF syndrome differentiation during treatment, so as to form optimal treatment to reduce re-admitted into hospitalization rate and mortality in patients with CHF.
