Recent studies have found that brown adipocytes may also regulate metabolism through autocrine, paracrine, and endocrine mechanisms. A growing body of evidences have shown that the BAT has a close relationship with bone metabolism, in which BAT secretes a variety of factors to regulate bone metabolism, while bone also secretes a variety of bioactive substances to control BAT function. In addition, BAT may indirectly participate in bone metabolism through muscle-mediated regulation or SNS activity and improvement of body metabolism, thus forming a BAT-skeletal axis. In this paper, we try to explain the relationship between brown adipose tissue and bone, and to discuss their interactive mechanisms. \u0000 \u0000 \u0000Key words: \u0000Brown adipose tissue; Bone metabolism; Endocrine factors","PeriodicalId":10120,"journal":{"name":"Chinese Journal of Endocrinology and Metabolism","volume":"35 1","pages":"995-998"},"PeriodicalIF":0.0,"publicationDate":"2019-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46017438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hippocampus and striatum tissues from hyperglycemia rat and normal SD rat(control group) were selected as specimens. Isobaric tags for relative and absolute quantification(iTRAQ) technique and 2-dimensional liquid chromatography-tandem mass spectrometry(2D-LC-MS/MS) were used for identifying the deferentially expressed proteins.

KEEN search indicated that the pathway of dopaminergic synaptic, complement, gap junction, autophagic and Fcgamma R-mediated phagocytosis were involved with these significant differentially expressed proteins. The protein interaction network showed that ferrin, aldehyde/ketone reductase(ARK), Ca2+ -binding protein(CaBP), and protein tyrosine phosphatase(PTP) were located at the crossed nodes.

A postmenopausal middle-aged woman, with a history of joint pain, fracture, and kidney stone which were neglected due to the lack of specificity of symptoms for years, went to hospital due to repeated epistaxis. Laboratory results showed high blood calcium, hypophosphatemia, alkaline phosphatase(ALP), and parathyroid hormone(PTH) levels, as well as increased urinary calcium. Imaging examination showed systemically multiple brown tumors and extensive osteoporosis. Meanwhile an abnormal mass was found behind the right thyroid. Taking all findings into account, the diagnosis was made with PHPT, and the histopathology further confirmed that the lesion was a parathyroid adenoma. This case seems to be a rare case of multiple brown tumor caused by parathyroid adenoma, which compressed and destructed nasal blood vessels, thus induced a repeated nasal discharge. After resection of parathyroid adenoma, the patient experienced a transient hypocalcemia and PTH level elevation. After 5-month follow up, part of the brown tumors spontaneously regressed, bone density increased, and her clinical symptoms were mostly relieved. \u0000 \u0000 \u0000Key words: \u0000Primary hyperparathyroidism; Parathyroid adenoma; Brown tumor; Epistaxis","PeriodicalId":10120,"journal":{"name":"Chinese Journal of Endocrinology and Metabolism","volume":"35 1","pages":"981-985"},"PeriodicalIF":0.0,"publicationDate":"2019-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46275206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
