Ethically, wish-fulfilling services confront the principles of the common morality if the autonomy of a patient is compromised, beneficence is unclear, harm is foreseeable, or distributive justice is compromised. selleck chemicals llc Wish-fulfilling dental treatment can be restricted by legislation if it conflicts with safe, effective and efficient care, or if it interferes with patient's real needs or undermines established professional standards. CONCLUSIONS The general understanding of wish-fulfilling medicine including its ethical and legal themes is relevant to dentistry. CLINICAL RELEVANCE Ethical considerations and legislation can guide a dentist to reflect critically on clinical decisions regarding wish-fulfilling dentistry. The antitumor activity of doxorubicin (DOX) is often limited owing to the occurrence of multidrug resistance (MDR) during treatment. Herein, we developed hybrid polymeric micelles, which consisted of pluronic F127 as long-circulating helper in blood, and phenylboronic ester-grafted pluronic P123 (PHE) as efflux and detoxification regulator to efficiently deliver DOX and reverse MDR in vivo. Hybrid F127/PHE micelles exhibited higher stability and drug encapsulation (~80%) than simple F127/P123 micelles due to its lower CMC, and displayed in vitro drug release in a hydrogen peroxide (H2O2)-sensitive manner. Besides, DOX-loaded hybrid micelles (F127/PHE-DOX) possessed higher cell-killing ability and induce more apoptotic in MDR-cells than other groups, which was probably because it not only could greatly increase intracellular drug concentration by inhibiting P-gp mediated drug efflux, but also promote reactive oxygen species (ROS) generation by decreasing glutathione (GSH) levels. Besides, in vivo evaluation indicated that F127/PHE-DOX could well accumulate at tumor regions and exhibit the strongest tumor growth inhibition (TGI 87.87%) accompanied with low side effects. As a result, F127/PHE micelles had great potentials as a platform for anticancer drugs delivery and tumor MDR reversal in clinical application. BACKGROUND Acute kidney injury (AKI) is common after cardiac arrest and targeted temperature management (TTM). The impact of different lengths of cooling on the development of AKI has not been well studied. In this study of patients included in a randomised controlled trial of TTM at 33°C for 24 versus 48hours after cardiac arrest (TTH48 trial), we examined the influence of prolonged TTM on AKI and the incidence and factors associated with the development of AKI. We also examined the impact of AKI on survival. METHODS This study was a sub-study of the TTH48 trial, which included patients cooled to 33±1˚C after out-of-hospital cardiac arrest for 24 versus 48hours. AKI was classified according to the KDIGO AKI criteria based on serum creatinine and urine output collected until ICU discharge for a maximum of seven days. Survival was followed for up to six months. The association of admission factors on AKI was analysed with multivariate analysis and the association of AKI on mortality was analysed with Cox regreration. AKI after cardiac arrest is an independent predictor of time to death. V.Recently studies showed that pregnane X receptor (PXR) was expressed in human brain microvessel endothelial cells and coordinately induced multidrug resistance protein 1 (MDR1) expression. The present study aimed to investigate the regulatory effect of Z-guggulsterone on MDR1 in human brain microvessel endothelial cells, and explored whether it involved modulation of PXR. The results showed that Z-guggulsterone (30 μM) simultaneously inhibited the expression of PXR and MDR1 at 24 h in human brain-derived microvessel endothelial cells (hBDMECs). Meanwhile, the levels of PXR and MDR1 expression were simultaneously reduced in PXR siRNA-transfected hBDMECs; MDR-1 siRNA-transfected hBDMECs showed significant decrease in MDR1 expression, but no change in PXR expression. Furthermore, Z-guggulsterone inhibited the activation of PXR in hBDMECs through decreasing the release of cAMP/PKA. Z-guggulsterone reduced the co-activator SRC-1 expression in hBDMECs, as to prevent the activation of MDR1 gene transcription. In addition, Z-guggulsterone (30 μM) at 24 h significantly inhibited the expression of human constitutive androstane receptor (CAR) protein in hBDMECs. However, after treatment with Z-guggulsterone (≤30 μM), the level of MDR1 reporter gene activity was lower in human PXR-transfected cells than that in human CAR-transfected cells. The inhibition effect of Z-guggulsterones on MDR1 reporter gene activation was gradually enhanced with the increase of human PXR to CAR ratio, which was greater extent than that with the increase of human CAR to hPXR ratio. The present study suggested that Z-guggulsterone down-regulating the efflux function and expression of MDR1 in hBDMECs might be mainly through the PXR-dependent manner. As recreational substances, synthetic cathinones started to be used at the beginning of the 21st century. There is still limited data on these compounds, introduced to the illicit drug market for the most part after 2009. Considering that synthetic cathinones are currently the second largest group of new psychoactive and dangerous substances among over 670 new psychoactive substances identified in Europe and monitored by the EMCDDA, research on them should be regarded as extremely important. This review focuses on the availability of synthetic cathinones on the illicit drug market, presentation of current trends in the use of these substances, and their mechanisms of action and toxicity. The authors discuss cases of intoxication with synthetic cathinones and post-mortem diagnostics as well as the problem of combined used of synthetic cathinones with other psychoactive substances. Literature as well as clinical and forensic data indicate the need for further research on the metabolism, toxicokinetics, toxicodynamics, clinical effects, and addictive potential of synthetic cathinones, especially in the context of potential threats caused by increased consumption of this group of drugs in future. Steroidal agent is a standard clinical treatment of atopic dermatitis; however, have serious side effects. Artesunate is reported to exhibit anti-inflammatory properties although its effect on atopic eczema remains unknown. We investigated the therapeutic effects and possible mechanism of systemic artesunate on DNCB-induced atopic dermatitis in a BALB/c mouse model. To ascertain artesunate (5 and 10 mg/kg) efficacy, skin dermatitis severity and ear, spleen, and lymph node weight were evaluated. Skin tissue mRNA and protein expression and serum cytokine levels were examined. Artesunate significantly improved atopic dermatitis symptoms, decreasing the dermatitis score, ear weight difference, spleen weight, and lymph node weight compared with those following DNCB treatment. Artesunate reduced ear and skin epidermal thickness and mast cell infiltration, as determined using hematoxylin-eosin and toluidine blue staining, respectively. The basal level of IgE (287.67 ± 70.41 ng/ml) and TNF-α (19.94 ± 3.98 pg/ml) were Significantly elevated by DNCB (IgE 1273.
