    lactis group received the probiotic only. For the CCl4 group, CCl4 was administered for 4 weeks. The experimental groups were all compared with the control group and the L. lactis + CCl4 group. Tissue samples were analyzed histologically and biochemically, and the gene expression levels of interleukin (IL)-1, IL-10 and forkhead box protein P3 (FoxP3) were determined. L. lactis decreased hepatic cirrhosis by preventing steatosis and fibrosis, and by reducing the levels of AST and ALT. Subchronic CCl4 injury induced upregulation of the IL-1β gene in the liver, which was decreased by L. lactis. It was also found that the group treated with L. lactis showed increased expression of Foxp3 in the liver and IL-10 in the gut. These results suggested that oral administration of L. lactis may be a potential probiotic to prevent or protect against CCl4-induced liver injury.Demodex infection gradually develops to Demodex blepharitis, which is characterized as chronic inflammation of the eyelid and meibomian gland (MG) and ultimately leads to MG dysfunction. In the present prospective study, the anti-demodectic effects of an okra eyelid patch in patients Demodex blepharitis were investigated. A total of 52 patients with Demodex blepharitis with ocular discomfort were recruited. Patients were randomized to receive either an okra eyelid patch treatment (treatment group, n=27) or tea tree oil (TTO) eye care patch treatment (control group, n=25) for three months. The Demodex count, the ocular surface disease index (OSDI) score, MG expressibility (MGE) and meibum quality, Schirmer I test (SIT), tear break-up time (TBUT) and corneal fluorescein staining (CFS) were determined prior to treatment and after 1 and 3 months of treatment. Changes in the parameters were compared between the treatment group and control group after 1 and 3 months of treatment. The average survival time in the oktch treatment is able to significantly eradicate ocular Demodex as well as markedly alleviate ocular symptoms. Due to causing less irritation than TTO, the okra eyelid patch may be more suitable for sensitive patients with Demodex blepharitis, such as the elderly and children. The study was registered as a clinical trial in the Chinese Clinical Trial Registry (ChiCTR) in November 2018 (registration no. ChiCTR-1,800,019,466).[This corrects the article DOI 10.3892/etm.2017.4116.].Osteoporosis is a common complication of long-term use of glucocorticoids (GCs) characterized by the loss of bone mass and damage of the microarchitecture as well as osteoblast dysfunction. Previous studies have demonstrated that microRNA-22 (miR-22) is the negative modulator of osteogenesis that may target caveolin-3 (CAV3), which has been reported to enhance bone formation and inhibit the progression of osteoporosis as well as apoptosis. The present study aimed to investigate whether miR-22 may be involved in dexamethasone (DEX)-induced inhibition of osteoblast differentiation and dysfunction by regulating CAV3 expression. Selleckchem MEK inhibitor Reverse transcription-quantitative PCR (RT-qPCR) was performed to measure the expression of miR-22 and western blotting was performed to determine protein levels. The results demonstrated that miR-22 expression was upregulated in DEX-treated osteoblastic cells compared with the control group. In addition, miR-22 mimic aggravated, whereas miR-22 inhibitor mitigated DEX-induced damage in osteoblastic cells compared with the control groups. Additionally, CAV3 was identified as the target of miR-22 in osteoblasts using RT-qPCR, western blotting and dual-luciferase reporter gene assay analysis. The results also demonstrated that silencing of CAV3 blocked the beneficial effects of miR-22 inhibitor against DEX-induced cell damage and apoptosis in osteoblasts, as evidenced by the increased expression levels of cleaved caspase-3, Bax and alkaline phosphatase activity as well as decreased cell viability and Bcl-2 levels. Collectively, these results indicate a novel molecular mechanism by which miR-22 contributes to DEX-induced osteoblast dysfunction and apoptosis via the miR-22/CAV3 pathway.MicroRNAs (miRs) are relevant in biological processes, including human prostate cancer. In the present study, the role of miR-769-5p and its targets in prostate cancer were explored. Publicly available data on expression of genes, miRs and disease-free survival of patients with prostate cancer were analyzed along with RNAseq of transfected cell lines. miR-769-5p expression was inversely associated with patient survival and in vitro assays indicated that its inhibition reduced the proliferation and increased apoptosis of prostate cancer cells. miR-769-5p was revealed to target Rho GTPase activating protein 10 (ARHGAP10) and increased expression of ARHGAP10 in tumors was determined to be associated with a favorable prognosis regarding disease-free survival. Of note, ARHGAP10 is a purported tumor suppressor in ovarian cancer, where it inhibits cell division cycle 42 (CDC42) activity and increases apoptosis. Similar effects were observed in prostate cancer cells, where miR-769-5p inhibition increased ARHGAP10 and led to reduced CDC42 activity. Furthermore, miR-769-5p inhibition increased apoptosis, which was partly reversed by additional knockdown of ARHGAP10. These results suggested that miR-769-5p is an oncogene targeting ARHGAP10, which in turn is a candidate tumor suppressor in prostate cancer.Accumulating evidence suggests that ionizing radiation (IR)-induced cataract may be associated with oxidative stress. Nuclear factor erythroid 2-related factor 2 (Nrf2) serves as a master regulator of the antioxidant defense system against oxidative stress. The present study aimed to investigate the effects of different doses of neutron radiation on the Nrf2-reegulated antioxidant defense system in rat lens and assess the status of oxidative stress. A total of 24 SD rats were randomly divided into the following four groups i) Control group; iis) 0.4 Sv group; iii) 1.2 Sv group; and iv) 3.6 Sv group. The rats were sacrificed 7 days after radiation and lenses were dissected for histological, biochemical (malondialdehyde, glutathione and superoxide dismutase) and western blot (Nrf2, glutamate-cysteine ligase catalytic subunit and heme oxygenase 1) analyses. The morphological features of the lenses remained intact in the 0.4 Sv, 1.2 Sv and control groups, whilst the lenses in the 3.6 Sv group exhibited injuries. Results from the TUNEL assay demonstrated apparent apoptosis in lens epithelial cells following 3.
