ABSTRACT

Tumor calcinosis(TC) has different clinical and biochemical patterns. The existence of chronic injury as well as calcium and phosphorus metabolism disorder has been gradually proved to be the important link in the occurrence of TC. In this paper, the related basic diseases with the pathophysiological mechanism of calcium and phosphorus metabolism disorder were reviewed, and the pathophysiological mechanism of phosphate metabolism disorder in various diseases was summarized.In addition, the phosphate homeostasis genes including GALNT-3, FGF-23 and α-KLOTHO were described. The relevant research results have showed that mutations in any of these three genes will lead to defects in the synthesis or action of FGF-23, which will increase the reabsorption of phosphate by renal tubules, resulting in hyperphosphatemia and severe ectopic calcification of soft tissue.At present, surgical resection is still the main treatment of TC. New technologies such as cinalcet peritoneal dialysis, ultrasound-guided aspiration of TC lesions and local injection of sodium thiosulfate (STS), as well as the successful application of lanthanum carbonate and other drugs, provide alternatives to TC treatment.In this paper, the research literatures on TC at home and abroad in recent years were introduced and the genetic susceptibility genes, related pathogenic factors and the latest treatment progress of TC were reviewed.

ABSTRACT

Objective:To study the relationship between compartmental kneeosteoarthritis (KOA) and osteoporosis (OP).Methods:A total of 118 KOA patients with 50~80 years old and 16.5~38 of body mass index (BMI) were selected as the KOA group, in which the patient with OP caused by secondary factors were excluded. 42 patients who did not suffer from KOA who matched the age of patients in the KOA group were selected. The age, BMI, bone mineral density (BMD) and other data of the two groups of patients were collected. The correlation analysis between KOA and OP was conducted to determine the degree of correlation, so as to reveal the relationship between the incidence, progression, prognosis of KOA and OP.Results:BMD was correlated with BMI. BMD was negatively correlated with age. The incidence of KOA and OP was correlated with age. There is a large correlation between KOA and OP, and the probability of KOA associated with OP is high. For KOA patients, OP is less likely to be accompanied by a higher BMI, while OP is more likely to be accompanied by a lower BMI.Conclusions:OP is one of the pathogenic factors of KOA. KOA patients should be treated with anti-OP before and after surgery.
