血清胃饥饿素、脂肪因子与膝骨关节炎患者骨密度的相关性研究

目的探讨血清胃饥饿素、脂肪因子水平与膝骨关节炎(knee osteoarthritis)患者骨密度(bone mineral density,BMD)之间的相关性。方法本研究选取了164例有症状的膝骨关节炎患者和100位健康人群(对照组)。使用酶联免疫吸附试验(ELISA)测量受试者血清胃饥饿素、脂联素和抵抗素水平。通过双能X线吸收测定法(DXA)测量受试者全身、腰椎、髋部和股骨的BMD。结果膝骨关节炎受试者的全身、腰椎、髋关节、股骨的BMD水平低于对照组(P均<0.05);但脂联素及胃饥饿素水平明显高于对照组(P均<0.05);在单因素分析中,血清胃饥饿素水平与所测量各个部位的骨密度之间有显著的负相关性(P<0.05);脂联素与股骨干骨密度和总股骨骨密度呈显著负相关(P<0.05)。进一步调整年龄、性别、体质量指数(body mass index,BMI)和骨关节炎(osteoarthritis,OA)后,胃饥饿素水平与各个部位的骨密度之间仍然存在显著负相关(P<0.05);脂联素与股骨干、股骨的骨密度之间有显著的相关性(P<0.05)。而血清抵抗素与各部位骨密度在混杂因素调整前后未发现显著相关性。结论血清胃饥饿素和脂联素水平与BMD呈显著负相关,提示胃饥饿素和脂联素对膝骨关节炎患者BMD有潜在的不利影响。

Adipokines in dental pulp: Physiological,pathological, and potential therapeutic roles

BackgroundHundreds of adipokines have been identified, and their extensive range of endocrine functions—regulating distant organs such as oral tissues—and local autocrine/paracrine roles have been studied. In dentistry, however, adipokines are poorly known proteins in the dental pulp; few of them have been studied despite their large number. This study reviews recent advances in the investigation of dental-pulp adipokines, with an emphasis on their roles in inflammatory processes and their potential therapeutic applications.HighlightsThe most recently identified adipokines in dental pulp include leptin, adiponectin, resistin, ghrelin, oncostatin, chemerin, and visfatin. They have numerous physiological and pathological functions in the pulp tissue: they are closely related to pulp inflammatory mechanisms and actively participate in cell differentiation, mineralization, angiogenesis, and immune-system modulation.ConclusionAdipokines have potential clinical applications in regenerative endodontics and as biomarkers or targets for the pharmacological management of inflammatory and degenerative processes in dental pulp. A promising direction for the development of new therapies may be the use of agonists/antagonists to modulate the expression of the most studied adipokines.     

Adiponectin protects rat heart from left ventricular remodeling induced by chronic intermittent hypoxia via inhibition of TGF-β/smad2/3 pathway

Objective

Obstructive sleep apnea syndrome (OSAS) is associated with many cardiovascular disorders. Chronic intermittent hypoxia (CIH) is the primary player in OSAS of the many associated factors. This study was in order to investigate the effects of the Adiponectin (Ad) on left ventricular remodeling induced by CIH.

Methods

Forty-five rats were randomly divided into three groups: normal control (NC) group, CIH group and CIH plus Ad supplemented (CIH + Ad) group. After 35 days’ CIH exposure, masson analysis was used to detect the left ventricular fibrosis and western blot was used to measure the protein expression of collagen I, collagen III and TGF-β/smad2/3 pathway. Gene analysis by RT-PCR was used to study the MMP2 and TIMP2.

Results

After CIH exposure, the fibrosis of left ventricular in CIH group was significantly remarkable than that in both NC and CIH + Ad groups (P<0.05), although statistical difference existed between NC and CIH + Ad groups (P<0.05). In addition, the protein expression of collagen I as well as collagen III and the ratio of mRNA levels of MMP2/TIMP2 were the highest in CIH group but the lowest in NC group, with CIH + Ad group in between. There was a significant difference among three groups (all P<0.05). The TGF-β/smad2/3 pathway was activated obviously in CIH group, but less noticeably in CIH + Ad group (P<0.05) with a significant difference in the two groups.

Conclusions

The present study showed that Ad could ameliorate the left ventricular remodeling induced by CIH via inhibition of the expression of TGF-β/smad2/3 pathway.
