The aim of this study was to compare out-of-hospital cardiac arrest (OHCA) outcomes before and after implementation of Smart Advanced Life Support (SALS) protocol incorporating changes in cardiopulmonary resuscitation (CPR) assistance and coaching by physicians via real-time video calls.

A prospective before-and-after multi-regional observational study was conducted between January 2014 and December 2018. In January 2016, emergency medical service (EMS) providers adopted an integrated CPR coaching by physicians via real-time video call via SALS to treat patients with OHCA focusing on high-quality cardiopulmonary resuscitation. Propensity score matching was performed to match patients. Patients' outcomes using conventional protocol were then compared with those of patients using the SALS protocol.

Among 26,349 OHCA cases, 2351 patients and 7261 patients were enrolled during the pre-intervention and the post-intervention periods, respectively. Multivariate analysis showed that SALS was independently associated with favorable neurological outcomes [odds ratio (OR) 2.20; 95% confidence interval (CI) 1.62-2.99]. A total of 2096 patients were propensity score-matched and the two groups were well balanced. In the matched cohort, the use of SALS protocol was still associated with increased prehospital return of spontaneous circulation (ROSC) (OR 3.83, 95% CI 2.80-5.26), survival to discharge (OR 1.68; 95% CI 1.20-2.34), and favorable neurological outcomes (OR 1.83; 95% CI 1.19-2.82).

A multidisciplinary SALS protocol for the resuscitation of patients with OHCA was associated with increased prehospital ROSC, survival to discharge, and good neurologic outcomes compared with traditional resuscitation protocol.

The knowledge of important players during this process remains limited. We previously reported that the aquaporin RhPIP1;1 plays an important role in ethylene-regulated petal cell expansion in rose flower. Here, we identified RhRab5ip as a new interactor of RhPIP1;1. RhRab5ip belongs to the Rab5-interacting protein (Rab5ip) family and may function in vesicle trafficking pathway. By using split ubiquitin yeast two-hybrid (SUY2H) system, bimolecular fluorescence complementation (BiFC) and subcellular colocalization we confirmed the existence of physical interaction between RhPIP1;1 and RhRab5ip in yeast and plant cell. The interaction of these two proteins happened at the small punctate structures in the cytoplasm. Expression of RhRab5ip in petals increased substantially at the initial stage of flower opening and maintained at high level until flower wilting. The transcripts of both RhRab5ip and RhPIP1;1 were greatly up-regulated by ABA and GA3 treatments, while only RhPIP1;1 was down-regulated by ethylene. Moreover, both RhRab5ip and RhPIP1;1 were significantly induced by water deficit treatment after 12 h-treatment, when flowers started to wilt and showed neck bending. Taken together, these findings suggested that RhRab5ip might functionally coordinate with RhPIP1;1 in response to water deficit stress in rose flower, expanding our understanding of the possible involvement of Rab5ip protein in the regulatory network of flower opening during water deficit.Diabetic ulcer is a challenging complication of diabetes mellitus but current treatments cannot achieve satisfactory results. In this study, the effect of Huangbai liniment (HB) and berberine on the wound healing in high fat diet/streptozotocin injection induced diabetic rats was investigated by RNA-seq technology. HB topical treatment promoted wound healing in the diabetic patients and diabetic rats, and it affected multiple processes, of which IL-17 signalling pathway was of importance. Inhibiting IL-17a by its inhibitor or antibody remarkably facilitated wound healing and HB significantly repressed the high IL-17 expression and its downstream targets, including Cxcl1, Ccl2, Mmp3, Mmp9, G-CSF, IL1B and IL6, in diabetic wounds, promoted T-AOC, SOD activity and GSH levels; decreased the levels of nitrotyrosine and 8-OHdG; enhanced angiogenesis-related CD31, PDGF-BB and ANG1 expression; inhibited cleaved caspase-3 levels and promoted TIMP1 and TGFB1. Moreover, berberine (a major component in HB) repressed the IL-17 signalling pathway, and promoted wound healing in diabetes mellitus. This study highlights the strategy of targeting IL-17a in diabetic wounds, deepens the understanding of wound healing in diabetes mellitus in a dynamic way and reveals the characteristics of HB and berberine in promoting wound healing of type 2 diabetes mellitus.Reactive oxygen species (ROS) are key regulators of the proliferation, metastasis, and drug resistance of melanoma, which accounts for 60% of skin cancer deaths. In a previous study, we developed Dudleya brittonii water extract (DBWE) with antioxidant activity, but the mechanism of action and bioactive substances of DBWE have not been fully identified. This study showed altered NADPH oxidase 2 (NOX2) expression and selective inhibition of cytosolic ROS but not mitochondrial ROS in B16-F10 melanoma cells, suggesting the NOX2 inhibitory potential of DBWE. In addition, DBWE inhibited mitochondrial activity, lipid metabolism, and cell cycle in B16-F10 cells. The anti-melanoma effect of DBWE was abrogated by the addition of ROS, and there was no significant change in the melanogenesis pathway. Polygalatenoside A was identified as a candidate bioactive substance in the DBWE aqueous fraction through mass spectrometry, and the DBWE-like anti-melanoma effect was confirmed. These data suggest that DBWE and polygalatenoside A have the potential to prevent and treat melanoma.The metabolism, tissue distribution and excretion of taxifolin in rat after oral administration of taxifolin encapsulated zein-caseinate Nanoparticles (TZP) were studied. The isomerization of taxifolin in rat small intestine and colon was found. Besides isomers, 16 metabolites of taxifolin were identified in rat feces, plasma and urine by UPLC-QTOF-MS. In colon, taxifolin underwent the metabolism of hydration, dehydration and ring-fission through the gut microflora. The main metabolites of taxifolin found in plasma and urine were its sulfated, glucuronidated, and/or methylated products. The dynamic variation of taxifolin and its metabolites in tissues and urine were quantified by UPLC-QqQ-MS/MS. Taxifolin and its metabolites could be quickly absorbed and distributed in the tissues, and relatively low concentrations were found in the heart and brain. The feces excretion of taxifolin was determined by HPLC. The total excretion during 24 h was 2.83 ± 0.80% to its given does, and the maximum excretion was found during 8-10 h post administration. Compared with feces, the excretion of taxifolin and its metabolites in urine was much faster, and the total excretion was 1.96 ± 0.23% during 12 h.
Despite many liver disorders, clinically useful drugs are scarce. Moreover, the available therapies are facing the challenges of efficacy and safety. Alhagi camelorum has been used in folk medicine globally for millennia to treat several ailments. Alhagi camelorum (Ac) is an old plant with a significant therapeutic value throughout Africa, Asia, and Latin America. Our goal was to determine the hepatoprotective activity of Alhagi camelorum against valproic acid induced hepatotoxicity using an animal model.

The animals were segregated in 4-groups (6 male rats each) weighing 250-290g. Group-1 animals were treated with normal saline, Group-2 animals were treated with VPA at the dose of 500mg/kg i.p for 14 days consecutively, while Group-3 and 4 were treated with valproic acid (VPA) at the dose of 500mg/kg i.p for 14 days along with 400mg/kg and 600mg/kg of Ac hydroalcoholic extract respectively. Subsequently, blood serum samples and liver tissues were collected for biochemical and histopathological analysis. g i.p for 14 days along with 400 mg/kg and 600 mg/kg of Ac hydroalcoholic extract respectively. Subsequently, blood serum samples and liver tissues were collected for biochemical and histopathological analysis. Phytochemical screening was carried out to screen for phytochemical classes and HPLC analysis was conducted to screen polyphenols. The antioxidant activity was carried by different assays such as DPPH, SOD, NO etc. KEY RESULTS The administration of Ac showed hepatoprotection at the doses of 400 and 600 mg/kg. Ac significantly reduces the elevated serum levels of liver biomarkers compared to the valproic acid-induced hepatotoxic group. These findings were confirmed with histopathological changes where Ac was capable of reversing the toxic effects of valproic acid on liver cells CONCLUSION It is concluded that Ac showed significant hepatoprotective effects at different doses in the animal model used in this study.Granulocyte colony-stimulating factor (G-CSF) is one of the cytokines which plays important roles in embryo implantation and normal pregnancy. At the maternal-fetal interface, G-CSF can be synthesized by multiple cells, and participates in regulation of trophoblast development, endometrial decidualization, placental metabolism and angiogenesis. Moreover, as an important medium of intercellular communication, G-CSF has also been shown to exert key roles in crosstalk between cellular components at the maternal-fetal interface. Recently, our study demonstrated that G-CSF derived from M2 macrophage could promote trophoblasts invasion and migration through activating PI3K/AKT/Erk1/2 pathway, thereby involving in normal pregnancy program. Herein, we will summarize the role and regulation of G-CSF in normal pregnancy and reproductive-related disease, and the clinical applications of G-CSF in patients undergoing in vitro fertilization with thin endometrium, repeated implantation failure, and women suffered with recurrent spontaneous abortion.Phosphorylation is a posttranslational modification of proteins that regulates many cellular processes, such as communication between cells, cell proliferation, cell movements, and gene expression. Therefore, many studies have been conducted to determine the significance and function of phosphorylation. These studies involve the identification of phosphorylation site(s), kinases and phosphatases, and regulatory mechanisms. Selleck 5-Ethynyl-2'-deoxyuridine Recently, phosphorylation sites were identified using mass spectrometry and detected by immunoblotting with phosphorylation site-specific antibodies. However, the in vivo phosphorylation profile of the target protein is not easy to grasp, and the quantification of site-specific phosphorylation is challenging if the protein is phosphorylated at multiple sites. Phos-tag is a phospho-affinity SDS-PAGE approach in which phosphorylated proteins are separated depending on the number and sites of phosphorylation during electrophoresis, which overcomes the aforementioned problems. We applied this technique to perform an in vivo analysis of the phosphorylation of many proteins.
