The results indicated that ZnO nanoparticles markedly inhibit HTFs viability and decrease the Δψm in a concentration-dependent pattern. Exposure of HTFs to ZnO nanoparticles could also induce the elevated Caspase-3, Caspase-9, and Apaf-1 expression, decrease the levels of FSP-1, collagen III, and E-cadherin expression, leading to HTFs apoptosis. Our results suggested that elevated ROS and activated Caspase signaling play a fundamental role in ZnO nanoparticle-induced HTFs apoptosis. 5-lipoxygenase is a key enzyme in the synthesis of leukotrienes from arachidonic acid. The produced leukotrienes are involved in inflammatory diseases including psoriasis, asthma, and atherosclerosis. A suitable 5-lipoxygenase inhibitor might be useful for preventing and improving the symptoms of leukotriene-related inflammatory diseases. Here, we investigate the mechanism underlying the anti-inflammatory effect of a proanthocyanidin found in red-kerneled rice. Red-kerneled rice proanthocyanidin exhibited potent mixed noncompetitive inhibition of 5-lipoxygenase, with an IC50 of 7.0 μM. This compound decreased leukotriene B4 production in rat basophilic leukemia-2H3 cells. In imiquimod-induced psoriasis-like mouse skin, topical application of the proanthocyanidin suppressed hyperplasia, decreased inflammatory cell infiltration, and down-regulated expression of the psoriasis-associated genes Il17a, Il22, S100a9, and Krt1. Lipid metabolome analysis by electrospray ionization mass spectrometry showed that red-kerneled rice proanthocyanidin treatment of psoriasis-like mouse skin dose-dependently decreased the production of leukotriene B4 but no other arachidonate metabolites. Red-kerneled rice proanthocyanidin inhibits 5-lipoxygenase, resulting in a decrease in leukotriene B4 production and psoriasis-like mouse skin inflammation. These results suggest that this proanthocyanidin may be therapeutically effective for treating leukotriene-related diseases. BACKGROUND Blocking the interaction between PD-1 and its ligands is a promising treatment strategy for advanced hepatocellular carcinoma. This study aimed to assess the antitumour activity and safety of the anti-PD-1 inhibitor camrelizumab in pretreated patients with advanced hepatocellular carcinoma. METHODS This is a multicentre, open-label, parallel-group, randomised, phase 2 trial done at 13 study sites in China. Eligible patients were aged 18 years and older with a histological or cytological diagnosis of advanced hepatocellular carcinoma, had progressed on or were intolerant to previous systemic treatment, and had an Eastern Cooperative Oncology Group performance score of 0-1. Patients were randomly assigned (11) to receive camrelizumab 3 mg/kg intravenously every 2 or 3 weeks, via a centralised interactive web-response system using block randomisation (block size of four). The primary endpoints were objective response (per blinded independent central review) and 6-month overall survival, in all randomltiple organ failure). INTERPRETATION Camrelizumab showed antitumour activity in pretreated Chinese patients with advanced hepatocellular carcinoma, with manageable toxicities, and might represent a new treatment option for these patients.

Peptide receptor radionuclide therapy can prolong progression-free survival in these patients. Tamoxifen Additional treatment of liver disease might further improve outcomes. We aimed to investigate the safety and efficacy of additional holmium-166 (166Ho) radioembolisation after peptide receptor radionuclide therapy in patients with metastatic liver neuroendocrine neoplasms. METHODS The Holmium Embolization Particles for Arterial Radiotherapy Plus 177Lu-Dotatate in Salvage Neuroendocrine Tumour Patients (HEPAR PLuS) study was a single-centre, phase 2 study done at the University Medical Center Utrecht (Utrecht, Netherlands). Patients, aged at least 18 years, with histologically proven grade 1 or 2 neuroendocrine neoplasms of all origins, an Eastern Cooperative Oncology Group performance status of 0-2, and three or more measurable liver metastases according to Rlide therapy. A future randomised, controlled study should investigate the added benefit of this treatment on progression-free survival. FUNDING None. BACKGROUND Severe maternal morbidity continues to be an issue of national and global concern and is increasing in incidence. The incidence of infertility is also on the rise, and infertile women experience a higher risk of incident chronic medical disease and cancer, suggesting that fertility may serve as a window to a woman's overall health. OBJECTIVE To investigate the risk of severe maternal morbidity by maternal fertility status. STUDY DESIGN Retrospective cohort analysis using Optum's de-identifed Clinformatics® Data Mart Database between 2003-2015. Infertile women stratified by infertility diagnosis, testing or treatment were compared to fertile women seeking routine gynecologic care. In both groups, only women who underwent pregnancy and delivery of a singleton during the follow up period were included. Main outcomes were severe maternal morbidity indicators, defined by the CDC, and identified by ICD-10 and CPT codes within 6 weeks of each delivery. Results were adjusted for maternal age, race, educatiated among infertile Black women, who face similar risks as infertile Caucasian women. BACKGROUND Literature on the use of bowel preparation in gynecologic surgery is scarce and limited to minimally invasive gynecologic surgery. The decision on the use of bowel preparation before benign or malignant hysterectomies is mostly driven by extrapolating data from the colorectal literature. OBJECTIVE Bowel preparation is a controversial element within enhanced recovery protocols, and literature investigating its efficacy in gynecologic surgery is scarce. Our aim was to determine if mechanical bowel preparation (MBP) alone, oral antibiotics (OA) alone, or a combination are associated with decreased rates of surgical site infections (SSI) or anastomotic leaks (AL) compared to no bowel preparation following benign or malignant hysterectomy. STUDY DESIGN We identified women who underwent hysterectomy between January 2006 and July 2017 using OptumLabs, a large US commercial health plan database. Inverse propensity score weighting was used separately for benign and malignant groups to balance baseline characteristics.
