Receptor-interacting serine/threonine-protein kinase 1 (RIPK1) functions as a key regulator in inflammation and cell death and is involved in mediating a variety of inflammatory or degenerative diseases. A number of allosteric RIPK1 inhibitors (RIPK1i) have been developed, and some of them have already advanced into clinical evaluation. Recently, selective RIPK1i that interact with both the allosteric pocket and the ATP-binding site of RIPK1 have started to emerge. Here, we report the rational development of a new series of type-II RIPK1i based on the rediscovery of a reported but mechanistically atypical RIPK3i. We also describe the structure-guided lead optimization of a potent, selective, and orally bioavailable RIPK1i, 62, which exhibits extraordinary efficacies in mouse models of acute or chronic inflammatory diseases. Collectively, 62 provides a useful tool for evaluating RIPK1 in animal disease models and a promising lead for further drug development.

120 extracted maxillary first premolars were endodontically treated and randomly divided into 5 groups(n=24).The teeth in group A had 4 walls of coronal tooth structure,in group B,C,D and E had only 3 walls,missing the palatal,buccal,mesial and distal wall,respectively.The teeth in group A0-E0(n=6)were restored without post,in group A1-E1(n=6)with buccal post,in group A2-E2(n=6)with palatal post,in group A3-E3(n=6)with buccal and palatal post,respectively.The fracture resistance of group A was higher than that of B,C,D and E groups(P＜0.05).The fracture resistance of fiber posts placed in the buccal root canal was higher than that in the palatal root canal(P＜0.05).The 360° complete ferrule can provide the best fracture resistance,When the ferrule is not complete,it is recommended to place buccal fiber post for repair.

Objective To investigate the clinical diagnostic value of circulating tumor cells (CTCs)and circulating cell-free DNA (cfDNA) in peripheral blood samples in breast cancer. Methods From July 2017 to April 2018, 47 patients with BMC (7 in stage Ⅱ, 19 in stage Ⅲ and 21 in stage Ⅳ), 24 patients with benign breast diseases and 28 healthy people were selected. After collecting peripheral blood samples, serum and blood cells were separated. The size-based high-throughput microfluidic chip was used to capture CTCs. The real-time fluorescent quantitative PCR based on Alu sequence was used to detect the length of cfDNA(247 bp, 115 bp)in the serum, and the ratio of amplified products of long and short fragments was used as the index of DNA integrity. The Mann-Whitney U test or Kruskal-Wallis H test was used to compare the differences between the groups and analyze the relationship between CTCs and cfDNA and clinical parameters of breast cancer. The ROC curve was drawn and the area under the curve (AUC) was used to evaluate the feasibility of blood cell CTCs and plasma cfDNA detection as diagnostic criteria. Results The CTCs and cfDNA of 47 BMC patients were analyzed. The CTCs and cfDNA integrity index (Alu 247/115) of BMC patients were significantly higher than those of physical examination patients[(13.98± 12.36)cells / ml vs (1.14 ± 1.35) cells / ml; 0.7687 ± 0.3868 vs 0.5094 ± 0.2456], and the difference was statistically significant(the U value was 126.5,359.0;P<0.001), the area under ROC curve of CTCs was 0.885 (95％CI: 0.805-0.965), cut-off value was 7.68/ml, sensitivity was 80.4％, specificity was 96.4％. The area under ROC curve of Alu 247/115 was 0.727(95％CI: 0.608-0.847), cut-off value was 0.431, sensitivity was 71.7％, specificity was 71.4％. The AUC of CTCs and Alu 247/115 was 0.919 (95％CI 0.854-0.984), which was higher than the single test of each indicator. Conclusions CTCs and cfDNA may be the potential biological indicators for breast cancer diagnosis. The combined detection of CTCs and cfDNA maybe improve the diagnosis rate of breast cancer patients.

Objective To evaluate the effect of tyrosol on myocardial ischemia-reperfusion (I/R) injury in diabetic rats and the role of silent mating-type information regulation 1 (SIRT1)/adenosine monophosphate-activated protein kinase (AMPK)/endothelial nitric oxide synthase (eNOS) signaling pathway.Methods SPF healthy adult male Sprague-Dawley rats,weighing 200-220 g,were intraperitoneally injected with streptozotocin 60 mg/kg to establish the model of diabetes mellitus.Fifty-six diabetic rats were divided into 4 groups (n =14 each) using a random number table method:sham operation group (S group),myocardial I/R group (I/R group),myocardial I/R plus tyrosol group (I/R+T group),and myocardial I/R plus tyrosol plus SIRT1 inhibitor EX527 group (I/R+T+E group).In I/R+T and I/R+T+E groups,tyrosol 20 mg · kg-1 · d-1 was given by gavage for 45 consecutive days,and the equal volume of normal saline was given in the other two groups.In I/R+T+E group,EX527 5 mg · kg-1 · d-1 was intraperitoneally injected for 3 consecutive days before ischemia,and EX527 5 mg/kg was intraperitoneally injected at 20 min before repeffusion.Myocardial I/R was induced by ligation of the left anterior descending branch of coronary artery for 30 min followed by 2-h reperfusion.The myocardial infarct volume was measured by TTC staining.The levels of creatine kinase-MB (CK-MB),lactic dehydrogenase (LDH) and 5-F2t-isoprostane in serum and superoxide dismutase (SOD) in myocardial tissues were detected by enzyme-linked immunosorbent assay.The expression of SIRT1,AMPK,phosphorylated AMPK (p-AMPK),eNOS and p-eNOS was detected by Western blot.Results Compared with S group,the levels of serum CK-MB,LDH and 15-F2t-Isoprostane and myocardial infarction volume were significantly increased,the SOD activity was decreased,and the SIRT1 expression was down-regulated in I/R group,and the levels of serum CKMB,LDH and 15-F2t-Isoprostane and myocardial infarction volume were significantly increased,the SOD activity was decreased,the SIRT1 expression was down-regulated,and the expression of p-AMPK and peNOS was up-regulated in I/R+T and I/R+T+E groups (P＜0.05).Compared with I/R group,the levels of serum CK-MB,LDH and 15-F2t-Isoprostane and myocardial infarction volume were significantly decreased,the SOD activity was increased,and the expression of SIRT1,p-AMPK and p-eNOS was up-regulated in I/R+T group (P＜0.05),and no significant change was found in the parameters mentioned above in I/R+ T+E group (P＞0.05).Compared with I/R+T group,the levels of CK-MB,LDH and 15-F2t-isoprostane in serum and myocardial infarct volume were significantly increased,the SOD activity was increased,and the expression of SIRT1,p-AMPK and p-eNOS was down-regulated in I/R+T+E group (P＜0.05).Conclusion Tyrosol can mitigate myocardial I/R injury,and the mechanism may be related to activating SIRT1/AMPK/eNOS signaling pathway and inhibiting oxidative stress response in diabetic rats.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.
