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.

Objective To evaluate the role of phosphatase and tensin homologue deleted on chromosome 10 (PTEN) in diabetes mellitus-induced reduction of hypoxic postconditioning (HPO)-induced protection of cardiomyocytes and the relationship with glycogen synthase kinase-3β (GSK-3β)-mediated mitochondrial apoptotic pathway.Methods H9c2 cells incubated in high-glucose (30 mmol/L) medium for 24 h were divided into 6 groups (n =5 each) using a random number table:normoxia group (group N),hypoxia-reoxygenation (H/R) group,group HPO,PTEN gene silencing normoxia group (group P-N),PTEN gene silencing H/R group (group P-H/R),and PTEN gene silencing HPO group (group P-HPO).H9c2 cells were exposed to 95％ N2-5％ CO2 for 4 h followed by 2 h reoxygenation with 90％ O2-10％ CO2.HPO was induced by 3 cycles of 5 min reoxygenation followed by 5 min hypoxia before reoxygenation.At the end of reoxygenation,the level of lactate dehydrogenase (LDH) in the supernatant was detected by enzyme-linked immunosorbent assay,the changes in mitochondrial membrane potential (MMP were assessed by JC-1 fluorescence assay,the cell apoptosis was detected by AnnexinV-FITC/PI flow cytometry,and the expression of PTEN and phosphorylated GSK-3β (p-GSK-3β) was determined by Western blot.The JC-1 monomer/polymer ratio and apoptosis rate were calculated.Results Compared with group N,the amount of LDH released,JC-1 monomer/polymer ratio and apoptosis rate were significantly increased,and the expression of PTEN was up-regulated in H/R and HPO groups (P＜0.05).There was no significant difference in the parameters mentioned above between group H/R and group HPO (P＞0.05).Compared with group HPO,the amount of LDH released,JC-1 monomer/polymer ratio and apoptosis rate were significantly decreased,PTEN expression was down-regulated,and the expression of p-GSK-3β was up-regulated in group P-HPO (P＜0.05).Compared with group N,the expression of PTEN was significantly down-regulated,and no significant changes were found in the other parameters mentioned above in group P-N (P＞0.05).Compared with group H/R,the expression of PTEN was significantly down-regulated,and no significant changes were found in the other parameters mentioned above in group P-H/R (P＞0.05).Conclusion PTEN is involved in diabetes mellitus-induced reduction of HPO-induced protection of cardiomyocytes,and the mechanism is associated with PTEN-induced activation of GSK-3β-modulated mitochondrial apoptotic pathway.

Objective To observe the effects of electro-acupuncture (EA) at “Weizhong” (BL40) on expressions of Fas and FasL in rat models with lumbar disc degeneration; To discuss its mechanism of action.MethodsThirty SD rats were randomly divided into sham-operationgroup, model group and EA group, with 10 rats in each group. The sham-operation group was treated with sham operation to incide local skin; the model and EA groups established rat model of lumbar disc degeneration by puncturing the annulus fibrosus. Four weeks after modeling, rats in the sham-operation and model groups received fixed treatment under identical condition, and rats in the EA group were treated with EA at “Weizhong” (BL40) in 20 minutes, once a day, for 4 weeks. After treatment, Western blot and RT-PCR technology were used to test the protein and mRNA expression levels of Fas and FasL.ResultsThe expressions of Fas and FasL in the model group were higher than those in the sham-operation group (P<0.05); protein and mRNA expression levels of Fas and FasL in the EA group were lower than those in the model group (P<0.05). ConclusionEA at “Weizhong” (BL40) can reduce the expressions of Fas and FasL to inhibit the development of lumbar disc degeneration.

Objectives To observe the clinical significance and application value of autologous blood transfusion in neurosurgery of primary hospital. Methods Four hundred and fourteen patients who underwent the neurosurgery operation and were subjected to intraoperative blood transfusion were selected, among whom 97 patients were subjected to autologous blood transfusion (observation group), and 317 patients were subjected to heterogenous blood transfusion (control group). The condition of intraoperative blood transfusion, changes of hemoglobin and hematocrit, blood transfusion related cost were compared between 2 groups. Results There were no statistical differences in operation time, infusion volume, rate of transfusion related complications and postoperation hemoglobin, hematocrit between observation group and control group (P>0.05). The patients in control group were infused with 189 000 ml, and the transfusion liquid volume proportion of total blood transfusion was 79.22%(189 000/238 580);13 patients in observation group were used the heterogenous blood transfusion with 5 400 ml, and the transfusion liquid volume proportion of total blood transfusion was 10.30%(5 400/52 430). Eighty-six patients (88.66%, 86/97) in observation group performed autologous blood collection and transfusion, the volume of autologous collection was 80 650 ml, and the volume of transfusion was 47 020 ml. Eleven patients in observation group did not perform autologous blood transfusion, among whom 6 patients was because of operational and mechanical reasons, and 5 patients performed collection but did not transfuse. The cost of heterogenous concentrated suspension red blood cell over 6 U was significantly higher than the cost of disposable material and injection of autologous blood:(2 287.06 ± 243.52) yuan vs. (1 595.08 ± 133.95) yuan, and there was statistical difference (P<0.05). The rate of heterogenous concentrated suspension red blood cell 6 U in control group was 14.83%(47/317), and the rate of over 6 U was 6.62%(21/317). Conclusions The autologous blood transfusion is safe and effective, and it is worth popularizing in neurosurgery of primary hospital. But in the process of its application, it is necessary to strengthen the user′s operating skills and ensure the quality of autologous blood transfusion.

Objective To explore the effect of electroacupuncture at Weizhong (BL40) acupoint on the expression of Bcl-xL and Bax in rats with lumbar disc degeneration. Methods Thirty male adult Sprague-Dawley rats were randomly divided into sham-operated group (n= 10), model group (n=10), and electroacupuncture group (n=10). The lumbar disc degeneration model was established by puncturing the annulus fibrosis in the model group and electroacupuncture group. One month after modeling, the electroacupuncture group was electroacupunctured at Weizhong acupoint for four weeks. HE staining was used to observe the pathological changes. Immunohistochemical staining was used to observe the expression of Bax in the lumbar disc tissue. Western blotting was used to detect the expression of Bcl-xL and Bax protein. Results HE staining showed that the degrees of lumbar disc degeneration from light to severe was ranged as: the sham-operated group, the electroacupuncture group and the model group. The expression of Bcl-xL was lower (P<0.05), and the expression of Bax was higher (P<0.01) in the model group than in the sham-operated group, which was opposite (P<0.01) in the electroacupuncture group than in the model group. Conclusion Electroacuponcture at Weizhong may upregulate the expression of Bcl-xL and downregulate the expression of Bax in rats with lumbar disc degeneration.

OBJECTIVEThe decoction of Astragali Radix and Angelicae Sinensis Radix (A&A) has shown antifibrotic effects in rats with unilateral ureteral obstruction (UUO). The aim of this study was to track the effective parts of A&A for its renoprotective effects, according to the improvement of renal function and renal tubulointerstitial damage.

METHODA&A was sequentially extracted by using different solvents for three times and eleven different parts were gained. Wistar rats were randomly divided into Sham, UUO and the treatment groups with A&A or each part of A&A. After administration of A&A or its parts for 10 days, the levels of serum creatinin (Scr) and urea were measured. The morphological changes of kidneys were also semi-quantitatively analyzed by HE, Masson stained tissue sections, which including interstitial cell infiltration, tubular atrophy and interstitial fibrosis.

RESULTThe levels of Scr, urea were significantly increased, accompanied with severe renal damage in rats with UUO. As same as A&A, the part I in the first extraction and part IC in the second extraction were all shown to decrease the levels of Scr and urea and the index of renal interstitial damage. However, the following 4 parts extracted from IC in the third extraction were shown no effect on the above indexes.

CONCLUSIONThe extract part I and part IC could be considered as the predominant parts of A&A for its renoprotective effects, due to their improvement of renal damage in interstitial nephropathy.
