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 study the changes of metabolites in chronic heart failure ( CHF ) patients of blood stasis pattern by applying nuclear magnetic resonance ( NMR) . Methods Demographic data were collected from CHF patients of blood stasis pattern using cross-section survey. Their blood samples were also obtained and then magnetic resonance spectrum with pattern recognition techniques were used for in-tegral calculation and normalization based on chemical shift. All data were imputed into SIMCA-P soft-ware and the results were analyzed by using orthogonal projections to latent structures-discriminant analy-sis ( OPLS-DA) model. Results The OPLS-DA analysis of plasma samples could differentiate and pre-dict blood stasis pattern. Increased levels of lactate, alanine, and pyruvic acid with decreased levels of histidine, glycine, valineas, and other metabolites constitute the metabolomics profile of blood stasis pat-tern. Conclusion This study showed a profile of altered metabolites related to energy utilization and fat-ty acid metabolism in plasma samples of CHF patients with blood stasis pattern, which could offer a new approach to the diagnosis and treatment of CHF.

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.
