Study on The Current Status and Progress of Clinical Application of Ciprofol

Ciprofol,as a new type of short-acting intravenous anesthetic drug,belongs to the category of gamma-aminobutyric acid(GABA)receptor agonists.Its unique chemical structure,through the introduction of the cyclopropyl group in the isopropyl side chain of propofol,constructs a new type of chiral molecule,which significantly enhances the spatial effect,and improves the affinity for GABA receptors.Its pharmacological properties are characterized by high potency,rapid onset of action,rapid recovery,low accumulation,and minimal adverse reactions.Therefore,it has a wide range of applications in various endoscopic diagnostic and therapeutic operations,ICU sedation,and general anesthesia.In this paper,the related knowledge of ciprofol and the development of clinical application research are comprehensively sorted out and synthesized,to provide a solid theoretical basis for the rational application of ciprofol in clinical practice.At the same time,the future research direction of ciprofol will also be prospected to provide valuable references for research in related fields.

Diagnostic and prognostic role of neutrophil-to-lymphocyte ratio(NLR) in sepsis

Objective: To evaluate neutrophil-to-lymphocyte ratio(NLR) as diagnostic and prognostic role in sepsis. Methods: It was a prospective, observational study, conducted in Intensive Care Unit of Mianyang Central Hospital , from August 2017 to August 2018. A total of 37 cases of newly diagnosed cases of sepsis were included in the study and 20 healthy adults were taken as controls. According to the mortality within 30 d,patients with sepsis were divided into survival group (n=15) and death group (n=22) . The white blood cell (WBC), neutrophils count (NEU), lymphocyte count (LYM), and NLR in peripheral blood were recorded at 1, 3,5,7 days after admission for patients . Logistic regression analysis was used to evaluate the risk factors for predicting the outcome, and receiver-operating characteristic curve (ROC) was plotted for evaluating the value of these factors on the 30-day prognosis. Results: NLR on day 1 (NLR1) of sepsis was signifcantly higher as compared to controls (P<0.001), with far higher diagnostic efficiency (AUC=0.959) than WBC (AUC=0.788) and equivalent to NEU% (AUC=0.942);WBC and NLR on day 7 (NLR7) is independent risk factors for 30-day mortality of sepsis patients and is helpful to predict the prognosis of sepsis. Conclusion: NLR can be a convenient and useful diagnostic and prognostic marker in sepsis and is of great clinical applicative value for primary hospitals without ability to detect other costly biomarkers and for emergency department.

Toll-like receptor 10 (TLR10) exhibits suppressive effects on inflammation of prostate epithelial cells

Prostate inflammation (PI) is closely related to the development and progression of chronic prostatic diseases: benign prostatic hyperplasia and prostate cancer. Toll-like receptor (TLR) 2 has been reported to be associated with inflammatory diseases, such as infections, autoimmune diseases, and cancers. Meanwhile, TLR10, which can form heterodimers with TLR2, has been considered an orphan receptor without an exact function. The present study therefore aims to examine the effects of TLR2 and TLR10 on PI. Prostate samples and clinical data were obtained from the patients diagnosed with benign prostatic hyperplasia. The inflammatory cell model was established by adding lipopolysaccharide to RWPE-1 cells. Prostate tissues/cells were examined by histological, molecular, and biochemical approaches. Both TLR2 and TLR10 were found to be expressed in prostate tissues and RWPE-1 cells. mRNA/protein expression levels of TLR2 and TLR10 were both positively correlated with prostate tissue inflammatory grades. Lipopolysaccharide-stimulated RWPE-1 cells expressed higher levels of TLR2, TLR10, high mobility group box 1 (HMGB1), phosphonuclear factor kappa-light-chain-enhancer of activated B-cells P65 (phospho-NF-κB P65), interleukin (IL)-6, and IL-8 than control cells. Moreover, HMGB1, phospho-NF-κB P65, IL-6, and IL-8 were down regulated after TLR2 knockdown and upregulated after TLR10 knockdown in RWPE-1 cells. TLR2 stimulation can activate the inflammatory signaling cascade in prostate epithelial cells. Conversely, TLR10 exhibited suppressive effects on inflammation. With antagonistic functions, both TLR2 and TLR10 were invoIved in PI. TLR10 could be a novel target in modulating inflammatory signal transduction of prostate epithelial cells.
