Abstract
Low back pain (LBP) is the world's leading cause of disability and is increasing in prevalence more rapidly than any other pain condition. Intervertebral disc (IVD) degeneration and facet joint osteoarthritis (FJOA) are two common causes of LBP, and both occur more frequently in elderly women than in other populations. Moreover, osteoarthritis (OA) and OA pain, regardless of the joint, are experienced by up to twice as many women as men, and this difference is amplified during menopause. Changes in estrogen may be an important contributor to these pain states. Receptors for estrogen have been found within IVD tissue and nearby joints, highlighting the potential roles of estrogen within and surrounding the IVDs and joints. In addition, estrogen supplementation has been shown to be effective at ameliorating IVD degeneration and OA progression, indicating its potential use as a therapeutic agent for people with LBP and OA pain. This review comprehensively examines the relationship between estrogen and these pain conditions by summarizing recent preclinical and clinical findings. The potential molecular mechanisms by which estrogen may relieve LBP associated with IVD degeneration and FJOA and OA pain are discussed.

Abstract
Here, the antibiotic levofloxacin (LFX) widely used and detected in the environment was degraded by photoelectrolysis using a new electrode based on zinc oxide (ZnO) and a mixture of mixed oxides of ruthenium and titanium (MMO). The influence of the potential and irradiation of UV light was investigated in the photostability of the Ti/MMO/ZnO electrode and in the degradation of the antibiotic. The experiments were conducted at different pH values (5.0, 7.0 and 9.0) in sodium sulfate solution in a glass reactor with central lighting. It was observed that the new Ti/MMO/ZnO electrode has good stability under light irradiation and potential, presenting excellent photocurrent and high photoactivity in LFX photoelectrolysis. The removal efficiency of the compound was directly related to the formation of oxidizing species in solution, the photo-generated charges on the electrode and the electrostatic characteristics of the molecule. The mineralization rate, the formation of reaction intermediates and short chain carboxylic acids (acetic, maleic, oxalic and oxamic acid), in addition to the formation of N-mineral species (NO3- and NH4+) was dependent on the pH of the solution and the investigated processes: photoelectrolysis was more efficient than photolysis, which, in turn, was more efficient than electrolysis. The synergistic effect and the high rate of degradation of LFX after 4.0 h of treatment (100%) observed in photoelectrolysis at alkaline pH, was associated with the high stability of the Ti/MMO/ZnO electrode at this pH, the photoactivation of sulfate ions and the ease generation of oxidizing radicals, such as OH.

Abstract
Fluoroquinolones (FQs) has caused increasing concerns regarding its potential environmental risks. However, their effects on bacterial community and microbial interactions in wetland system remains unclear. To verify these issues, a lab-scale constructed wetland exposed to low concentration FQs mixture was carried out for two months. The results showed that the removal efficiencies of COD and TP were negatively affected. FQs significantly increased the bacterial diversity and altered the overall bacterial community structure. Proteobacteria significantly decreased while Firmicutes exhibited opposite tendency (P < 0.05). Dechloromonas and Delftia, involved in phosphorus removal, decreased significantly (P < 0.05). Molecular ecological network analysis suggested that FQs promoted the network complexity and microbial interactions. A super module emerged at FQs and among-module connections were weakened obviously. Additionally, Nodes of Betaproteobacteria lost most interactions while Clostridia acquired more interactions at the presence of FQs. This study provided insights into how the bacterial community and their molecular ecological network respond to FQs in constructed wetland system.

Abstract
PURPOSE To evaluate the association of postoperative fluoroquinolone use following arthroscopic primary rotator cuff repair with failure requiring revision rotator cuff repair. METHODS An insurance database was queried for patients undergoing rotator cuff repair from 2007 to 2015. These patients were divided into three groups: (1) patients prescribed fluoroquinolones within 6 months postoperatively (divided into 0-2, 2-4, and 4-6 months), (2) a matched negative control cohort of patients not prescribed fluoroquinolones, and (3) a matched positive control cohort of patients prescribed fluoroquinolones between 6 and 18 months following rotator cuff repair. Rates of failure requiring revision rotator cuff repair were compared within 2 years. RESULTS A total of 1292 patients were prescribed fluoroquinolones within 6 months after rotator cuff repair, including 442 within 2 months, 433 within 2 to 4 months, and 417 within 4 to 6 months, and were compared to 5225 matched negative controls and 1597 matched positive controls. The rate of revision rotator cuff repair was significantly higher in patients prescribed fluoroquinolones within 2 months (6.1 %) compared to matched negative (2.2 %, P = 0.0009) and positive controls (2.4 %, P = 0.0026). There were no significant differences in the rate of revision rotator cuff repair when fluoroquinolones were prescribed >2 months after rotator cuff repair. CONCLUSIONS Early use of fluoroquinolones following rotator cuff repair was independently associated with significantly increased rates of failure requiring revision rotator cuff repair. This is the first clinical study examining the association of postoperative fluoroquinolone use with failure following arthroscopic rotator cuff repair. LEVEL OF EVIDENCE III.

Abstract
The interactions of levofloxacin (LEV) with lysozyme (LYZ), trypsin and bovine hemoglobin (BHb) were investigated, respectively, by using multi-spectral techniques and molecular docking in vitro. Fluorescence studies showed that LEV quenched LYZ/trypsin fluorescence in a combined quenching ways and BHb fluorescence in a static quenching with binding constants of .14, .51 and .20 × 105 L mol-1 at 298 K, respectively. The thermodynamic parameters demonstrated that hydrophobic forces, hydrogen bonds, and van der Waals forces played the major role in the binding process. The binding distances between LEV and the inner tryptophan residues of LYZ, trypsin, and BHb were calculated to be 4.04, 3.38, and 4.52 nm, respectively. Furthermore, the results of circular dichroism spectra (CD), UV-vis, and three-dimensional fluorescence spectra indicated that the secondary structures of LYZ, trypsin, and BHb were partially changed by LEV with the α-helix percentage of LYZ-LEV system increased while that of BHb-LEV system was decreased, the β-sheet percentage of trypsin-LEV system increased from 41.3 to 42.9%. UV-vis spectral results showed that the binding interactions could cause conformational and some micro-environmental changes of LYZ, trypsin, and BHb. The results of molecular docking revealed that in LYZ and trypsin systems, LEV bound to the active sites residues GLU 35 and ASP 52 of LYZ and trypsin at the active site SER 195, and in BHb system, LEV was located in the central cavity, which was consistent with the results of synchronous fluorescence experiment. Besides, LEV made the activity of LYZ decrease while the activity of trypsin increased.

Abstract
Levofloxacin was previously reported to induce apoptosis of rat annulus fibrosus (AF) cells by upregulating active caspase-3 and matrix metalloproteinase (MMP)-3 expression in vitro. However, the effects of levofloxacin on rat AF cells, as well as the related mechanism, have not been revealed completely. The purpose of this study was to further explore the changes in extracellular matrix and MMPs of rat AF cells based on levofloxacin-induced apoptosis. AF cells isolated from rat AF regions were cultured in monolayers and treated with levofloxacin in a dose- and time-dependent manner. To determine the cytotoxic effects of levofloxacin, inverted phase-contrast microscopy was used to perform morphological observation of apoptotic cells. The mRNA expression levels of MMP-2, -9 and -13 were quantified by reverse transcription and real-time quantitative polymerase chain reaction (RT-qPCR). Protein level of MMP-2 and MMP-13 were determined by western blot. The results showed that levofloxacin induced marked AF cell apoptosis, which was observed by inverted phase-contrast microscopy, and indicated by the increased expression of active caspase-3. Both RT-qPCR and western blot revealed that MMP-2 and MMP-13 expression were upregulated by levofloxacin treatment in a time- and dose-dependent manner. Moreover, cellular binding to type I collagen was found to be decreased by levofloxacin. In conclusion, the results above suggest that the possible cytotoxic effects of levofloxacin on AF cells in vitro may be attributed to the decreased cell binding to type I collagen and up-regulated expression of MMP-2 and MMP-13.
