Objective To explore influence of artesunate on T-bet /GATA-3 equilibrium of peripheral blood in oral lichen planus.Methods 18 OLP patients were selected,and peripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation. The cells were cultured and treated with different concentrations (0, 1, 100 μmol/L) of artesunate. Reverse transcription polymerase chain reaction (RT-PCR) and Western blot were applied to detect theT-bet and GATA-3 mRNA and protein expression respectively.Results The T-bet/GATA-3 mRNA and protein expressions in groups treated with artesunate (1 μmol/L & 100 μmol/L) were higher than that of control group (treated without artesunate) (P

Traumatic brain injury (TBI) is a major cause of morbidity and mortality globally. We unveiled the diagnostic value of serum NLRP3, metalloproteinase‐9 (MMP‐9) and interferon‐γ (IFN‐γ) levels in post‐craniotomy intracranial infections and hydrocephalus in patients with severe craniocerebral trauma to investigate the high risk factors for these in patients with TBI, and the serological factors predicting prognosis, which had a certain clinical predictive value. Study subjects underwent bone flap resection surgery and were categorized into the intracranial infection/hydrocephalus/control (without postoperative hydrocephalus or intracranial infection) groups, with their clinical data documented. Serum levels of NLRP3, MMP‐9 and IFN‐γ were determined using ELISA kits, with their diagnostic efficacy on intracranial infections and hydrocephalus evaluated by receiver operating characteristic curve analysis. The independent risk factors affecting postoperative intracranial infections and hydrocephalus were analysed by logistic multifactorial regression. The remission after postoperative symptomatic treatment was counted. The intracranial infection/control groups had significant differences in Glasgow Coma Scale (GCS) scores, opened injury, surgical time and cerebrospinal fluid leakage, whereas the hydrocephalus and control groups had marked differences in GCS scores, cerebrospinal fluid leakage and subdural effusion. Serum NLRP3, MMP‐9 and IFN‐γ levels were elevated in patients with post‐craniotomy intracranial infections/hydrocephalus. The area under the curve values of independent serum NLRP3, MMP‐9, IFN‐γ and their combination for diagnosing postoperative intracranial infection were 0.822, 0.722, 0.734 and 0.925, respectively, and for diagnosing hydrocephalus were 0.865, 0.828, 0.782 and 0.957, respectively. Serum NLRP3, MMP‐9 and IFN‐γ levels and serum NLRP3 and MMP‐9 levels were independent risk factors influencing postoperative intracranial infection and postoperative hydrocephalus, respectively. Patients with hydrocephalus had a high remission rate after postoperative symptomatic treatment. Serum NLRP3, MMP‐9 and IFN‐γ levels had high diagnostic efficacy in patients with postoperative intracranial infection and hydrocephalus, among which serum NLRP3 level played a major role. What is the central question of this study?Severe craniocerebral injury usually leads to the loss of nerve function: what is the diagnostic value of serum NLRP3, metalloproteinase‐9 (MMP‐9) and interferon‐γ (IFN‐γ) levels in the diagnosis of intracranial infections and hydrocephalus in patients with severe craniocerebral trauma after craniotomy?What is the main finding and its importance?Serum NLRP3, MMP‐9, and IFN‐γ levels had high diagnostic efficacy in patients with postoperative intracranial infection and hydrocephalus, among which serum NLRP3 level played a major role.

The properties and applications of Ag nanowires (AgNWs) are closely related to their morphology and composition. Therefore, controlling the growth process of AgNWs is of great significance for technological applications and fundamental research. Here, silver nanowires (AgNWs) were synthesized via a typical polyol method with the synergistic effect of Cl - , Br - , and Fe 3+ mediated agents. The synergistic impact of these mediated agents was investigated intensively, revealing that trace Fe 3+ ions provided selective etching and hindered the strong etching effect from Cl - and Br - ions. Controlling this synergy allowed the obtainment of highly uniform AgNWs with sub-30 nm diameter and an aspect ratio of over 3000. Transparent conductive films (TCFs) based on these AgNWs without any post-treatment showed a very low sheet resistance of 4.7 Ω sq -1 , a low haze of 1.08% at a high optical transmittance of 95.2% (at 550 nm), and a high figure of merit (FOM) of 1210. TCFs exhibited a robust electrical performance with almost unchanged resistance after 2500 bending cycles. These excellent high-performance characteristics demonstrate the enormous potential of our AgNWs in the field of flexible and transparent materials., Competing Interests: The authors declare no conflict of interest.
