BACKGROUND:With the aging of the global population,the incidence rate of osteoporosis is also increasing.It is very important to further understand its pathogenesis and propose new therapeutic targets.Recent studies have shown that ferroptosis is closely related to the pathogenesis of some bone diseases,such as inflammatory arthritis,osteoporosis and osteoarthritis. OBJECTIVE:To summarize the previous studies on the mechanism of ferroptosis in osteoporosis,so as to provide new therapeutic ideas and potential therapeutic targets for osteoporosis. METHODS:The first author used the computer to search the documents published from 2000 to 2022 in CNKI,WanFang,VIP,PubMed and Web of Science with the key words of"ferroptosis,osteoporosis,osteoblasts,osteoclasts,iron chelators,reactive oxygen species,nuclear factor erythroid 2-related factor 2,heme oxygenase-1,glutathione peroxidase 4,review"in Chinese and English.A total of 70 articles were finally included according to the inclusion criteria. RESULTS AND CONCLUSION:Ferroptosis is significantly different from necrosis,apoptosis and autophagy.In terms of cell morphology and function,it does not have the morphological characteristics of typical necrosis,nor does it have the characteristics of traditional apoptosis,such as cell contraction,chromatin condensation,the formation of apoptotic bodies and the disintegration of cytoskeleton.Contrary to autophagy,ferroptosis does not form a classical closed bilayer membrane structure(autophagic vacuole).Morphologically,ferroptosis is mainly manifested by obvious contraction of mitochondria,increased membrane density,and reduction or disappearance of mitochondrial cristae,which are different from other cell death modes.Iron overload can destroy bone homeostasis by significantly inhibiting osteogenic differentiation and stimulating osteoclast formation,leading to osteoporosis.Iron overload interferes with the differentiation of stem cells to osteoblasts,leading to a weakened osteoblast function and further imbalance of bone metabolism in the body,which eventually leads to osteoporosis.Stimulated by iron overload,osteoclast bone resorption is enhanced and bone loss exceeds new bone formation.Iron chelators have been proved to have osteoprotective effects by inhibiting osteoclast activity and stimulating osteogenic differentiation of osteoblasts.Its potential mechanism is related to inhibiting osteoclast differentiation and promoting osteoblast differentiation.Antioxidants can prevent reactive oxygen species production and inhibit bone absorption,thus improving bone metabolism and effectively preventing osteoporosis.
摘要
Extracellular vesicles are nanoscale vesicles secreted by cells, including exosomes and microvesicles. They can be ingested by recipient cells through a variety of mechanisms, transmitting intercellular information and regulating biological functions of recipient cells. Studies have found that extracellular vesicles are closely related to skin diseases, such as autoimmune diseases, pigmented diseases, tumors and wound healing, and play important biological roles in various physiological and pathological processes. This review summarizes updates on extracellular vesicles in dermatology.
摘要
Scutellarin is a flavonoid extracted from breviscapus, a traditional Chinese medicine. Pharmacological studies have shown that scutellarin has anti-inflammatory, antioxidant, anti-fibrosis, anti-tumor, improving cardiac and cerebral ischemia. In recent years, with the deepening of research on scutellarin, it was found that it could inhibit the tumor through multi-target and multi-pathway, and the anti-human colorectal cancer was related to the regulation of p53 pathway, Hedgelog pathway and erythropoietin generates liver cancer interactivator B2(EphrinB2).The anti-esophageal squamous cell carcinoma is related to protein kinaseB1 /protein kinaseB2( Akt1/Akt2).Anti-renal carcinoma and melanoma are associated with phosphatase and tension protein homologues(PTEN) and phosphatidylinositol 3-kinase(PI3K)/Akt/mammalian target of rapamycin(mTOR) pathway. Anti-lung cancer is related to Akt/mTOR/4E binding protein1(4EBP1) and signal transduction and transcriptional activator(STAT3 )signaling pathway. Anti-cervical cancer is related to pyruvate kinase 2(PKM2).Anti-breast cancer is associated with Hippo/YAP pathway. At the same time, scutellarin was found to prevent diabetic microangiopathy, atherosclerosis and non-alcoholic fatty liver disease by regulating glucose and lipid metabolism, but the mechanism of action was not well studied. A review of the literature found that scutellarin anti-tumor, atherosclerosis, diabetic microangiopathy, non-alcoholic fatty liver disease, osteoarthritis, osteoporosis mechanism of action lack of detailed summary. In this paper, the research progress of pharmacological action and mechanism of scutellarin in recent 5 years is reviewed, and Suggestions on its current research status and future direction are put forward, in order to speed up the discovery of pharmacological mechanism of scutellarin and provide scientific basis for its further development and utilization.
摘要
We assessed the role of diabetes mellitus (DM) on treatment effects in drug-susceptible initial pulmonary tuberculosis (PTB) patients. A prospective study was conducted in eight provinces of China from October 2008 to December 2010. We enrolled 1,313 confirmed drug-susceptible initial PTB patients, and all subjects received the treatment regimen (2H3R3E3Z3/4H3R3) as recommended by the national guidelines. Of the 1,313 PTB patients, 157 (11.9%) had DM; these patients had more sputum smear-positive rates at the end of the second month [adjusted odds ratios (aOR) 2.829, 95% confidence intervals (CI) 1.783-4.490], and higher treatment failure (aOR 2.120, 95% CI 1.565-3.477) and death rates (aOR 1.536, 95% CI 1.011-2.628). DM was a contributing factor for culture-positive rates at the end of the second month and treatment failure and death of PTB patients, thus playing an unfavorable role in treatment effects of PTB.

The objective of this prospective study of the risks of treatment failure in patients with drug-susceptible pulmonary tuberculosis (PTB) was to provide reference data to help develop a disease control strategy. Participants were recruited in eight provinces of China from October 2008 to December 2010. A total of 1447 patients with drug-susceptible PTB and older than 15 years of age were enrolled. Demographic characteristics, bacteriological test results, and patient outcome, i.e., cure or treatment failure were recorded and compared using the chi-square or Fisher's exact tests. Multivariate logistic regression was used to identify factors associated with risk of treatment failure. Of the 1447 patients who were enrolled, 1349 patients (93.2%) were successfully treated and 98 (6.8%) failed treatment. Failure was significantly associated with age 365 years [odds ratio (OR)=2.522, 95% confidence interval (CI): (1.097-5.801)], retreatment [OR=2.365, 95% CI: (1.276-4.381)], missed medicine [OR=1.836, 95% CI: (1.020-3.306)], treatment not observed [OR=1.879 95% CI: (1.105-3.195)], and positive culture result after the first [OR=1.971, 95% CI: (1.080-3.597)] and second month [OR=4.659, 95% CI: (2.590-8.382)]. The risk factors associated with treatment failure were age 365 years, retreatment, missed medication, treatment not observed, and positive culture at the end of month 1 or month 2. These risk factors should be monitored during treatment and interventions carried out to reduce or prevent treatment failure and optimize treatment success.

<p><b>OBJECTIVE</b>To investigate the in vitro protective effect of Pinus massoniana bark extracts (PMBE) against cisplatin-induced nephrotoxicity in human embryonic kidney cells (HEK293), and preliminarily study its mechanism.</p><p><b>METHOD</b>Human embryonic kidney cells (HEK293) were cultured in vitro. The MTT assay was adopted to test the effect of PMBE and cisplatin on growth of HEK293 cells, and the protective effect of PMBE on cisplatin-induced nephrotoxicity of HEK293, and then detect the intracellular reactive oxygen species (ROS), malondialdehyde (MDA), glutathione (GSH) content, catalase (CAT), superoxide dismutase (SOD) and activity of thioredoxin reductase (TrxR).</p><p><b>RESULT</b>PMBE could promote growth of HEK293 cells at low concentrations, but generate slight nephrotoxicity at high concentration. Cisplatin could inhibit growth of HEK293 cells, increase ROS and MDA content, while reducing SOD, CAT and TrxR. The pre-protective PMBE was added to reduce cisplatin's injury to HEK293 cells, ROS, MDA and GSH content, SOD, CAT and TrxR within certain range.</p><p><b>CONCLUSION</b>PMBE at specific concentration has the protective effect in cisplatin-induced nephrotoxicity in HEK293 cells. Its mechanism may be related to PMBE's antioxidant activity.</p>
