Abstract
Porphyrin-based photosensitizers have been widely utilized in photodynamic therapy (PDT), but they suffer from deteriorating fluorescence and reactive oxygen species (ROS) due to their close π-π stacking. Herein, a biocompatible pure organic porphyrin nanocage (Py-Cage) with enhanced both type I and type II ROS generation is reported for PDT. The porphyrin skeleton within the Py-Cage is spatially separated by four biphenyls to avoid the close π-π stacking within the nanocage. The Py-Cage showed a large cavity and high porosity with a Brunauer-Emmett-Teller surface area of over 300 m2 g-1, facilitating a close contact between the Py-Cage and oxygen, as well as the fast release of ROS to the surrounding microenvironment. The Py-Cage shows superb ROS generation performance over its precursors and commercial ones such as Chlorin E6 and Rose Bengal. Intriguingly, the cationic π-conjugated Py-Cage also shows promising type I ROS (superoxide and hydroxyl radicals) generation that is more promising for hypoxic tumor treatment. Both in vitro cell and in vivo animal experiments further confirm the excellent antitumor activity of the Py-Cage. As compared to conventional metal coordination approaches to improve PDT efficacy of porphyrin derivatives, the pure organic porous Py-Cage demonstrates excellent biocompatibility, which is further verified in both mice and rats. This work of an organic porous nanocage shall provide a new paradigm for the design of novel, biocompatible and effective photosensitizers for PDT.

Abstract
Photothermal therapy (PTT) represents a promising noninvasive tumor therapeutic modality, but the current strategies for enhancing photothermal effect have been mainly based on promoting thermal relaxation or suppressing radiative dissipation process of excited energy, leaving little room for further improvement in photothermal effect. Herein, as a proof of concept, we report the thermophoresis-enhanced photothermal effect with pure organic Janus-like nanoparticles (Janus-like NPs) for PTT. The Janus-like NPs are eccentrically loaded with compactly J-aggregated photothermal molecules (DMA-BDTO), which show red-shifted absorption wavelength and inhibited radiative decay as compared to individual molecules. Under NIR irradiation, the asymmetric heat generation at particle surface endows Janus-like NPs the active thermophoresis, which further increases collisions and converts kinetic energy into thermal energy, and Janus-like NPs exhibit significantly elevated temperature as compared to conventional NPs with homogenously distributed DMA-BDTO. Both in vitro and in vivo results confirm such thermophoresis-enhanced photothermal effect for improved PTT. Our new strategy of thermophoresis-enhanced photothermal effect shall open new insights for improving photothermal-related tumor therapy.

Abstract
X-ray induced photodynamic therapy (X-PDT) circumvents the poor penetration depth of conventional PDT with minimal radio-resistance generation. However, conventional X-PDT typically requires inorganic scintillators as energy transducers to excite neighboring photosensitizers (PSs) to generate reactive oxygen species (ROS). Herein, a pure organic aggregation-induced emission (AIE) nanoscintillator (TBDCR NPs) that can massively generate both type I and type II ROS under direct X-ray irradiation is reported for hypoxia-tolerant X-PDT. Heteroatoms are introduced to enhance X-ray harvesting and ROS generation ability, and AIE-active TBDCR exhibits aggregation-enhanced ROS especially less oxygen-dependent hydroxyl radical (HO•- , type I) generation ability. TBDCR NPs with a distinctive PEG crystalline shell to provide a rigid intraparticle microenvironment show further enhanced ROS generation. Intriguingly, TBDCR NPs show bright near-infrared fluorescence and massive singlet oxygen and HO•- generation under direct X-ray irradiation, which demonstrate excellent antitumor X-PDT performance both in vitro and in vivo. To the best of knowledge, this is the first pure organic PS capable of generating both 1 O2 and radicals (HO•- ) in response to direct X-ray irradiation, which shall provide new insights for designing organic scintillators with excellent X-ray harvesting and predominant free radical generation for efficient X-PDT.

Abstract
Membrane separation technology for CO2 capture in pre-combustion has the advantages of easy operation, minimal land use and no pollution and is considered a reliable alternative to traditional technology. However, previous studies only focused on the H2-selective membrane (HM) or CO2-selective membrane (CM), paying little attention to the combination of different membranes. Therefore, it is hopeful to find the optimal process by considering the potential combination of H2-selective and CO2-selective membranes. For the CO2 capture process in pre-combustion, this paper presents an optimization model based on the superstructure method to determine the best membrane process. In the superstructure model, both CO2-selective and H2-selective commercial membranes are considered. In addition, the changes in optimal membrane performance and capture cost are studied when the selectivity and permeability of membrane change synchronously based on the Robeson upper bound. The results show that when the CO2 purity is 96% and the CO2 recovery rate is 90%, the combination of different membrane types achieves better results. The optimal process is the two-stage membrane process with recycling, using the combination of CM and HM in all situations, which has obvious economic advantages compared with the Selexol process. Under the condition of 96% CO2 purity and 90% CO2 recovery, the CO2 capture cost can be reduced to 11.75$/t CO2 by optimizing the process structure, operating parameters, and performance of membranes.

Abstract
Accurate assessment of physical fatigue is crucial to preventing physical injury caused by excessive exercise, overtraining during daily exercise and professional sports training. However, as a subjective feeling of an individual, physical fatigue is difficult for others to objectively evaluate. Heart rate variability (HRV), which is derived from electrocardiograms (ECG) and controlled by the autonomic nervous system, has been demonstrated to be a promising indicator for physical fatigue estimation. In this paper, we propose a novel method for the automatic and objective classification of physical fatigue based on HRV. First, a total of 24 HRV features were calculated. Then, a feature selection method was proposed to remove useless features that have a low correlation with physical fatigue and redundant features that have a high correlation with the selected features. After feature selection, the best 11 features were selected and were finally used for physical fatigue classifying. Four machine learning algorithms were trained to classify fatigue using the selected features. The experimental results indicate that the model trained using the selected 11 features could classify physical fatigue with high accuracy. More importantly, these selected features could provide important information regarding the identification of physical fatigue.

Abstract
OBJECTIVE Energy Expenditure (EE) estimation plays an important role in objectively evaluating physical activity and its impact on human health. EE during activity can be affected by many factors, including activity intensity, individual physical and physiological characteristics, environment, etc. However, current studies only use very limited information, such as heart rate and step count, to estimate EE, which leads to a low estimation accuracy. METHODS In this study, we proposed a deep multi-branch two-stage regression network (DMTRN) to effectively fuse a variety of related information including motion information, physiological characteristics, and human physical information, which significantly improved the EE estimation accuracy. The proposed DMTRN consists of two main modules: a multi-branch convolutional neural network module which is used to extract multi-scale context features from inertial measurement unit (IMU) data and electrocardiogram (ECG) data and a two-stage regression module which aggregated the extracted multi-scale context features containing the physiological and motion information and the anthropometric features to accurately estimate EE. RESULTS Experiments performed on 33 participants show that our proposed method is more accurate and the average root mean square error (RMSE) is reduced by 22.8% compared with previous works. CONCLUSION The EE estimation accuracy was improved by the proposed DMTRN model with a well-designed network structure and new input signal ECG. SIGNIFICANCE This study verified that ECG was much more effective than HR for EE estimation and cast light on EE estimation using the deep learning method.

Abstract
Background During the coronavirus disease 2019 pandemic, the management of nosocomial infections became even more crucial. There is an urgent need to develop a competency model for healthcare practitioners to combat public health emergencies. Aim To determine practitioners' competency in hospital infection prevention and control measures. Methods A theoretical framework was developed based on a literature review, key informant interviews, the Delphi method and a questionnaire survey. These items were evaluated based on response rate, maximum score, minimum score and mean score. Factor analyses, both exploratory and confirmatory, were used to determine the structure of the competency model. Results The effective response rate for the questionnaire was 88.29%, and Cronbach's α-coefficient was 0.964. Factor analysis revealed a Kaiser–Meyer–Olkin score of 0.945. Bartlett's test gave a χ2-value of 10523.439 (df=435; P<0.001). After exploratory factor analysis, the five-factor model was retained, four items were deleted and a five-dimensional, 26-item scale was obtained. The new structure's confirmatory factor analysis revealed high goodness of fit (comparative fit index=0.921; Tucker–Lewis index=0.911; standardized root mean square residual=0.053; root mean square error of approximation=0.044). Conclusion The proposed scale is a useful tool to assess the competency of hospital infection prevention and control practitioners, which can help hospitals to improve infection prevention and control.

Abstract
BACKGROUND To explore the clinical efficacy, safety, and prevention of major adverse reactions of the non-steroidal anti-inflammatory drug celecoxib combined with OxyContin and Pregabalin in the treatment of cancerous pudendal neuralgia. METHODS A total of 51 patients presenting with pelvic malignancies with cancerous pudendal neuralgia were selected, and random number table method was used to allocate them to either the experimental group (n=27) or control group (n=24). The control group was treated with OxyContin combined with Pregabalin, and the experimental group was treated with Celecoxib on the basis of the control group. RESULTS At 24 hours after treatment, the clinical effective rate of the experimental group was 92.6%, which was significantly higher than the 66.7% of the control group (P<0.05). The numerical rating scale (NRS) scores of the 2 groups of participants on the 7th and 14th days after treatment were lower than before treatment (P<0.05), and the NRS scores of the participants in the experimental group had decreased more significantly. At the same time, the average daily consumption of OxyContin on the 7th and 14th day of the experimental group was lower than that of the control group (P<0.05). Compared with the control group, the incidence of constipation and dysuria in the experimental group was significantly reduced (P<0.05). Co-occurring in both groups during treatment, 10 participants with urinary dysfunction were treated with tamsulosin hydrochloride sustained-release capsules, no urinary retention occurred, catheterization was avoided, tamsulosin hydrochloride sustained-release capsules could be stopped after 1 week, and urination was smooth (P<0.05). After treatment, the quality of life of the 2 groups of participants had improved compared to before treatment, and the improvement was more significant in the experimental group. CONCLUSIONS When treating patients with cancerous pudendal neuralgia with OxyContin and Pregabalin, the addition of celecoxib has a significant effect, which can effectively improve the patient's pain, improve their quality of life to a certain extent, and reduce the consumption of OxyContin. Lowering the dose of OxyContin reduces the occurrence of adverse reactions related to the drug, especially the incidence of constipation and urinary retention. Tamsulosin hydrochloride sustained-release capsules can effectively relieve urinary disorders caused by OxyContin. TRIAL REGISTRATION Chinese Clinical Trial Registry ChiCTR2100046045.

Abstract
BACKGROUND Globally, there have been many cases of coronavirus disease 2019 (COVID-19) among medical staff; however, the main factors associated with the infection are not well understood. AIM To identify the super-factors causing COVID-19 infection in medical staff in China. METHODS A cross-sectional study was conducted between January 1st and February 30th, 2020, in which front-line members of medical staff who took part in the care and treatment of patients with COVID-19 were enrolled. Epidemiological and demographic data between infected and uninfected groups were collected and compared. Social network analysis (SNA) was used to establish socio-metric social links between influencing factors. FINDINGS A total of 92 medical staff were enrolled. In all participant groups, the super-factor identified by the network was wearing a medical protective mask or surgical mask correctly (degree: 572; closeness: 25; betweenness centrality: 3.23). Touching the cheek, nose, and mouth while working was the super-factor in the infected group. This was the biggest node in the network and had the strongest influence (degree: 370; closeness: 29; betweenness centrality: 0.37). Self-protection score was the super-factor in the uninfected group but was the isolated factor in the infected group (degree: 201; closeness: 28; betweenness centrality: 5.64). For family members, the exposure history to Huanan Seafood Wholesale Market and the contact history to wild animals were two isolated nodes. CONCLUSION High self-protection score was the main factor that prevented medical staff from contracting COVID-19 infection. The main factor contributing to COVID-19 infections among medical staff was touching the cheek, nose, and mouth while working.

Abstract
Laser cladding is so complex that small disturbances may cause defects. Developing on-line monitoring technology for laser cladding is thus a priority task. Compared with expensive spectrometers and high-speed cameras, an economical optical sensing system based on two different photodiodes was established to optimize laser parameters and help monitor abnormal working conditions. In order to find optimal parameters, a series of experiments was carried out under different operating parameters such as laser power, scanning speed, and powder feeding rate. A practical rule is summarized to optimize process parameters by analyzing the time domain characteristics of the optical signal. Several experiments under different working conditions were performed to detect abnormal working conditions. Not only can an abnormal situation be recognized, but its type can also be distinguished by analyzing optical signals in the time and frequency domains. The optical sensing system provides a better understanding and accurate evaluation of laser cladding.

Abstract
A 54 years old male patient with chronic leg ulcers was admitted in our hospital in November 2017. He was diagnosed as pyoderma gangrenosum by the pathological examination. Then the wound was treated with simple vacuum sealing drainage combined with irrigation of oxygen loaded fluid. This therapy overcame the shortage of hypoxia in the Tibetan Plateau on wound healing, resulting in a better wound healing. The patient was eventually cured and discharged from hospital.

Abstract
BACKGROUND/AIMS Kidney ischemia and reperfusion injury could cause microvascular barrier dysfunction, lung inflammatory cascades activation, and programmed cell death of pulmonary endothelium, leading to acute lung injury. Our study aimed at determining whether erythropoietin (EPO) can ameliorate lung dysfunction following renal ischemia and reperfusion (IR) injury and explored the underlying mechanisms. METHODS In vivo, C57BL/6 mice received EPO (6000 U/kg) before right renal vascular pedicles clamping for 30 minutes, followed by 24 hours of reperfusion. The lung histopathologic changes and inflammatory cytokines expression were assessed. In vitro, cultured human umbilical vein endothelial cells were treated with EPO, and apoptosis rate, proliferation capacity, and phosphorylation status of the Janus kinase-signal transducer and activator of transcription 3 (Jak-STAT3) pathway were measured respectively in the presence or absence of lipopolysaccharide stimulation. RESULTS In vivo, EPO remarkably attenuated pulmonary interstitial and alveolar epithelial edema caused by renal IR injury. In vitro, the proliferation capacity of human umbilical vein endothelial cells was significantly increased under EPO stimulation, which correlated with changes in Jak-STAT3 signaling. CONCLUSION Our data indicated that EPO is able to ameliorate acute lung tissue damage induced by renal IR, and at least in part, via the Jak-STAT3 pathway.

Abstract
OBJECTIVE We previously reported that genetic ablation of (Fibroblast Growth Factors Receptors) FGFR1 in knee cartilage attenuates the degeneration of articular cartilage in adult mice, which suggests that FGFR1 is a potential targeting molecule for osteoarthritis (OA). Here, we identified R1-P1, an inhibitory peptide for FGFR1 and investigated its effect on the pathogenesis of OA in mice induced by destabilization of medial meniscus (DMM). DESIGN Binding ability between R1-P1 and FGFR1 protein was evaluated by enzyme-linked immuno sorbent assay (ELISA) and molecular docking. Alterations in cartilage were evaluated histologically. The expression levels of molecules associated with articular cartilage homeostasis and FGFR1 signaling were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR), Western blotting and immunohistochemistry (IHC). The chondrocyte apoptosis was detected by terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) assay. RESULTS R1-P1 had highly binding affinities to human FGFR1 protein, and efficiently inhibited extracellular signal-regulated kinase (ERK)1/2 pathway in mouse primary chondrocytes. In addition, R1-P1 attenuated the IL-1β induced significant loss of proteoglycan in full-thickness cartilage tissue from human femur head. Moreover, this peptide can significantly restore the IL-1β mediated loss of proteoglycan and type II collagen (Col II) and attenuate the expression of matrix metalloproteinase-13 (MMP13) in mouse primary chondrocytes. Finally, intra-articular injection of R1-P1 remarkably attenuated the loss of proteoglycan and the destruction of articular cartilage and decreased the expressions of extracellular matrix (ECM) degrading enzymes and apoptosis in articular chondrocytes of mice underwent DMM surgery. CONCLUSIONS R1-P1, a novel inhibitory peptide for FGFR1, attenuates the degeneration of articular cartilage in adult mice, which is a potential leading molecule for the treatment of OA.

Abstract
The design of French VFCWs leads to the formation of a sludge layer at the surface of the first filters due to the retention of suspended solids from the percolation of unsettled wastewater. This layer plays a major role in the system but still little is known on its characteristics and evolutions. In this study, suspended solids and sludge deposits sampled from two French VFCW plants were analyzed by different methods in the objective to assess the evolution of particulate organic matter (POM) along the treatment chain and within the sludge layer, and identify relevant analytical indicators of these phenomena. The treatment chain included an aerobic trickling filter followed by FeCl3 injection and two successive stages of filters. Thermal analyses showed that OM contents of suspended solids decreased along the treatment chain. POM in inflow suspended solids was predominantly composed of reactive, biodegradable compounds which were partly hydrolyzed and mineralized notably at the trickling filter stage. 3D fluorescence spectra collected from aqueous POM extracts confirmed the evolution of organic matter from low-molecular reactive compounds to more complex and stable structures such as humic-like substances. FTIR confirmed the mineralization of POM's reactive constituents along the treatment chain by the decrease in the intensities of the characteristics bands of aliphatic compounds or proteins, and its humification in the sludge deposits through the relative increase of the bands at 1634cm-1 (vC=O) and 1238cm-1 (δC=O and/or δOH). Isotopic ratios δ2H/1H and δ15N/14N were found to be good indicators of POM evolutions. The higher values of δ2H/1H and δ15N/14N ratios measured in sludge deposits as compared to inflow suspended solids were related to POM humification and to microbial processes of POM hydrolysis and mineralization, respectively.

Abstract
UNLABELLED The present meta-analysis synthesized evidence from 10 articles encompassing 28 independent studies to verify the association between hypertension and osteoporotic fracture risk in women and men. Our results indicate that the risk of osteoporotic fracture among individuals with hypertension was higher than that among individuals without hypertension. INTRODUCTION Epidemiological studies have suggested that hypertension is related to osteoporotic fracture. However, discrepancies exist in the reported findings. In this study, a systematic review of relevant published articles was conducted to verify the association between hypertension and osteoporotic fracture risk in women and men. METHODS PubMed (1953_October 5th, 2016) and Embase (1974_October 5th, 2016) were systematically searched for relevant articles. Odds ratios (ORs) and confidence intervals (CIs) were derived using random effect models. Categorical, subgroup, heterogeneity, publication bias, and meta-regression analyses were conducted. RESULTS We analyzed 10 articles encompassing 28 independent studies, 1,430,431 participants, and 148,048 osteoporotic fracture cases. The risk of osteoporotic fracture among individuals with hypertension was higher (pooled OR = 1.33, 95% CI 1.25-1.40; I 2 = 72.3%, P < 0.001) than that among individuals without hypertension. The association between hypertension and fracture risk was slightly stronger in women (pooled OR = 1.52, 95% CI 1.30-1.79) than in men (pooled OR = 1.35, 95% CI 1.26-1.44). Studies conducted in Asia revealed results that were consistent with those of studies performed in Europe. CONCLUSIONS Hypertension is associated with osteoporotic fracture risk. However, the biological mechanisms underlying the effect of hypertension on osteoporotic fracture remain to be elucidated.

Abstract
OBJECTIVES The objective of this study was to perform a systematic review of the orthodontic literature with regard to efficiency, effectiveness and stability of treatment outcome with clear aligners compared with treatment with conventional brackets. METHODS An electronic search without time or language restrictions was undertaken in October 2014 in the following electronic databases: Google Scholar, the Cochrane Oral Health Group's Trials Register, Scopus, CENTRAL, MEDLINE via OVID, EMBASE via OVID and Web of Science. We also searched the reference lists of relevant articles. Quality assessment of the included articles was performed. Two authors were responsible for study selection, validity assessment and data extraction. RESULTS Four controlled clinical trials including a total of 252 participants satisfied the inclusion criteria. We grouped the trials into four main comparisons. One randomized controlled trial was classified as level 1B evidence, and three cohort studies were classified as level 2B evidence. Clear aligners appear to have a significant advantage with regard to chair time and treatment duration in mild-to-moderate cases based on several cross-sectional studies. No other differences in stability and occlusal characteristics after treatment were found between the two systems. CONCLUSIONS Despite claims about the effectiveness of clear aligners, evidence is generally lacking. Shortened treatment duration and chair time in mild-to-moderate cases appear to be the only significant effectiveness of clear aligners over conventional systems that are supported by the current evidence.

Abstract
The placement of metal stents is often used as a palliative treatment for malignant esophageal stenosis. We designed a novel stent that has been used clinically since 2011, and we therefore performed a retrospective study to compare the therapeutic effects of this novel metal stent to a conventional partially covered metal stent in patients with malignant esophageal strictures. The records of 201 consecutive patients who underwent placement of either the conventional partially covered metal stents (Group A, n = 92) or the new metal stents (Group B, n = 109) in the Endoscopy Center of General Hospital of Chengdu Military Command from October 2008 to March 2013 were reviewed. The median dysphagia score significantly improved in both groups 1 week following stent placement (P < 0.001). No significant differences were observed in success rate (P = 0.910) or the complication rate (P = 0.426) between groups. Six months after stent placement, recurrent dysphagia due to stent migration, tissue ingrowth or overgrowth or food obstruction occurred in 45% and 29% of patients in the conventional stent and new stent groups, respectively. The results of this retrospective study indicate that the new modified self-expandable metal stents (SEMS) is at least as safe and effective as the conventional partially covered SEMS in treatment of malignant esophageal strictures.

Abstract
Objective: To compare the clinical efficacy of the direct anterior approach (DAA) and the posterolateral approach (PLA) for total hip arthroplasty (THA) in the lateral decubitus position. Methods: From July to December, 2014, 104 patients randomly divided into two equal groups of the DAA group and the PLA group underwent unilateral primary THA procedures.All procedures were performed by the same surgeon in the Department of Orthopaedics, the Affiliated Anhui Provincial Hospital of Anhui Medical University.General data, perioperative index, postoperative function and radiological evaluation were recorded and statistically analyzed. Results: The patients had an average follow-up of 14 (range, 10-16) months.No significant differences were detected with respect to the operation time, incision length, preoperative Hb concentration and transfusion rate between two groups (P> 0.05 for all comparisons). However, there were significant differences associated with the intraoperative bleeding, postoperative drainage and postoperative Hb concentration in the two groups(P<0.05 for all comparisons). The DAA group showed significant superior outcomes compared with the PLA group in the Harris hip scores [(83.6±7.1) vs (79.8±6.6), P<0.05], WOMAC[ (28.9±6.1) vs (36.1±6.9), P<0.001], and VAS pain scores[ (2.2±0.9) vs (2.9±1.1), P<0.05]at 1 month after surgery. No differences were seen between the study groups in the evaluation of radiography and the incidence of adverse event (P> 0.05 for all comparisons). Conclusions: Compared with the posterolateral approach, the present study shows the exciting results in patients underwent the DAA THA in the lateral decubitus position at early follow-up.The advantages of THA using the DAA include less operative trauma, alleviation of postoperative pain, and faster postoperative rehabilitation. It is a safe, reliable and effective surgery approach.

Abstract
MicroRNAs (miRs) are associated with tumor progression in various cancers, such as gastric and hepatic carcinomas, and lung cancer. miR-301a is overexpressed and displays oncogenic activity in cancers. We investigated the biological involvement of miR-301a in osteosarcoma (OS). Quantitative real-time polymerase chain reaction (qRT-PCR) was used to analyze expression levels of miR-301a in 24 OS and matched adjacent non-tumor tissues. A miR-301a mimic was transferred into OS cell lines U-2 OS and MG-63 to upregulate miR-301a. The effects of miR-301a were investigated by examining cell proliferation, migration, and the cell cycle. The miR-301 target was predicted by TargetScan and confirmed by western blotting and qRT-PCR. The expression of miR-301a was significantly higher in OS tissues compared with the matched adjacent non-tumor tissues (0.959 ± 0.39 vs 3.9516 ± 1.18). Upregulated miR-301a significantly increased proliferation at 48 and 72 h compared to the negative control (U-2 OS: 2.11 ± 0.21 vs 2.88 ± 0.24; 2.70 ± 0.26 vs 3.71 ± 0.24; MG-63: 2.19 ± 0.20 vs 3.19 ± 0.22; 3.1 ± 0.25 vs 4.01 ± 0.27) and migration capability (U-2 OS: 100 ± 20.19 vs 150.68 ± 32.83; MG-63: 100 ± 17.20 vs 133.35 ± 26.26), and decreased apoptosis in both U-2 OS (10.87 ± 2.53 vs 4.01 ± 2.23) and MG-63 (15.26 ± 2.15 vs 8.25 ± 3.07). The cell cycle studies revealed that miR-301a caused an increase of the G2 population in U-2 OS (38.6 ± 6.58 vs 47.2 ± 7.27) and MG-63 (44.01 ± 5.28 vs 57.9 ± 4.25). Additional experiments indicated that CDC14A was upregulated by miR-301a (0.63 ± 0.06 vs 0.98 ± 0.06; 1.49 ± 0.25 vs 2.99 ± 0.14). Overexpressed miR-301a may increase CDC14A expression and promote cell proliferation and migration in OS cells. Therefore, miR- 301a may be useful for osteosarcoma diagnosis and therapy.

Abstract
AIM Inflammatory dentigerous cysts usually occur in the mixed dentition. It has been reported that inflammatory lesions from the root area of a deciduous tooth bring about the development of dentigerous cysts around the unerupted permanent tooth bud. Endodontic treatment is a common and successful procedure for periapical inflammation in children. An inflammatory dentigerous cyst can occur in conjunction with endodontically treated primary tooth. CASE REPORT This article reports a case of 6 years and 6 months old boy, with a single, well-defined, unilocular, radiolucent area enclosing the first right unerupted mandibular premolar, accidentally discovered on the panoramic radiograph. The first right primary molar had received a root canal treatment 18 months prior. Clinical findings combined with radiographic and microscopic examinations confirmed the diagnosis of inflammatory dentigerous cyst. As treatment, enucleation of the cyst with removal of the involved permanent tooth was chosen and a removable partial denture was supplied to the patient after surgery. The 5-year follow-up revealed good healing of the bony lesion and displaced teeth. CONCLUSION This case presented a severe and rare complication of endodontically treated primary tooth, and the recommendation includes: (1) early diagnosis of dentigerous cysts, which is essential to prevent extensive treatment; (2) more information on the adverse side effects of an endodontic treatment should be given to patients and parents; (3) patients should be informed about the importance of follow-ups and radiographic follow-up should be routinised.

Abstract
Apogossypolone (ApoG2), a novel derivative of gossypol, exhibits superior antitumor activity in Bcl-2 transgenic mice, and induces autophagy in several cancer cells. However, the detailed mechanisms are not well known. In the present study, we showed that ApoG2 induced autophagy through Beclin-1- and reactive oxygen species (ROS)-dependent manners in human hepatocellular carcinoma (HCC) cells. Incubating the HCC cell with ApoG2 abrogated the interaction of Beclin-1 and Bcl-2/xL, stimulated ROS generation, increased phosphorylation of ERK and JNK, and HMGB1 translocation from the nucleus to cytoplasm while suppressing mTOR. Moreover, inhibition of the ROS-mediated autophagy by antioxidant N-acetyl-cysteine (NAC) potentiates ApoG2-induced apoptosis and cell killing. Our results show that ApoG2 induced protective autophagy in HCC cells, partly due to ROS generation, suggesting that antioxidant may serve as a potential chemosensitizer to enhance cancer cell death through blocking ApoG2-stimulated autophagy. Our novel insights may facilitate the rational design of clinical trials for Bcl-2-targeted cancer therapy.

Abstract
AIM It has been recommended that patients with suspected colorectal cancer should proceed straight to an endoscopic test to increase speed of diagnosis, using only the information in the general practitioner's referral letter. This study aims to establish whether the diagnostic accuracy of the first surgical outpatient assessment is significantly greater than the general practitioner's assessment and if so by what means. METHOD Demographic variables, symptoms and signs were collected from the first surgical outpatient assessment letters and the general practitioners' referral letters in 2-week-wait colorectal cancer referrals made between 2002 and 2005. Multiple logistic regression models derived from both the surgeons' and the general practitioners' letters were compared with receiver operator characteristic curves. RESULTS Variables were collected from 978 2-week-wait colorectal cancer referrals. The median age was 69 years (range 19-98) and the male to female ratio was 1:2. Seventy-eight referrals were diagnosed with colorectal cancer. Surgeons' models demonstrated significantly greater diagnostic accuracy than general practitioners' models (area under the curve, 0.84 vs 0.73; P < 0.003). General practitioners' letters contained significantly less information than surgeons' letters (P < 0.001), but correcting for this did not account for the difference in diagnostic accuracy. The single variable that accounted for the difference in diagnostic accuracy was examination of the rectum by rigid sigmoidoscopy. CONCLUSION Rigid sigmoidoscopy significantly improves the diagnostic accuracy of clinical assessment in patients with suspected colorectal cancer. If rigid sigmoidoscopy were omitted in a straight-to-test pathway, some patients would be denied the opportunity for immediate diagnosis.

Abstract
Background Secreted phospholipase A(2) (sPLA(2) ) may be important mediators of asthma, but the specific sPLA(2) s involved in asthma are not known. Objective To evaluate sPLA(2) group IIA, V, and X proteins (sPLA(2) -IIA, sPLA(2) -V, and sPLA(2) -X) in bronchoalveolar lavage (BAL) fluid, BAL cells, and airway epithelial cells of subjects with and without asthma, and examine the relationship between the levels of specific sPLA(2) enzymes and airway inflammation, asthma severity, and lung function. Methods The expression of sPLA(2) -IIA, sPLA(2) -V, and sPLA(2) -X in BAL cells and epithelial brushings was assessed by qPCR. The levels of these sPLA(2) proteins and sPLA(2) activity with and without group II and group X-specific inhibitors were measured in BAL fluid from 18 controls and 39 asthmatics. Results The airway epithelium expressed sPLA(2) -X at higher levels than either sPLA(2) -IIA or sPLA(2) -V, whereas BAL cells expressed sPLA(2) -IIA and sPLA(2) -X at similar levels. The majority of sPLA(2) activity in BAL fluid was attributed to either sPLA(2) -IIA or sPLA(2) -X. After 10-fold concentration of BAL fluid, the levels of sPLA(2) -X normalized to total protein were increased in asthma and were associated with lung function, the concentration of induced sputum neutrophils, and prostaglandin E(2) . The levels of sPLA(2) -IIA were elevated in asthma when normalized to total protein, but were not related to lung function, markers of airway inflammation or eicosanoid formation. Conclusions and Clinical Relevance These data indicate that sPLA(2) -IIA and sPLA(2) -X are the major sPLA(2) s in human airways, and suggest a link between the levels of sPLA(2) -X in the airways and several features of asthma.

Abstract
Acute kidney injury (AKI) is a major complication in orthotopic liver transplantation (OLT). In an evaluation of Acute Kidney Injury Network (AKIN) criteria in liver transplanted patients, we retrospectively analyzed the usefulness of these criteria to predict survival of 193 consecutive patients at a single center who underwent primary OLT for clinical parameters and peak AKI. Postoperative AKI according to AKIN occurred in 60.1% of the patients, namely, stages 1, 2, and 3 in 30%, 13% and 17.1% respectively. Using multivariate logistic regression, AKIN stage 1 and 2 AKI were independently associated with the pre-OLT Model for End-Stage Liver Disease (MELD) score and age, while stage 3 AKI was independently associated with MELD and Acute Physiology and Chronic Health Evaluation (APACHE) II scores. The 28-day and 1-year mortality post-OLT of AKI patients were 15.5% and 25.9% respectively compared with 0% and 3.9% among non-AKI patients (P < .05 for both). The survival rates of non-AKI and stages 1, 2, and 3 AKI subjects were 96%, 85.5%, 84%, and 45.3%, respectively. Cox regression analysis showed independent risk factors for mortality during the first year after transplantation to include post-OLT AKI (12.1; P < .05), post-OLT infection (HR 4.7; P < .01), pre-OLT hypertension (HR 4.4; P < .01) hazard ratio [HR] and post-OLT APACHE II ≥10 (HR 3.6; P < .05). We concluded that AKI as defined by the AKIN criteria is a major complication of OLT linked to a poor outcomes. It remains to be evaluated whether aggressive perioperative therapy to prevent AKI can improve survival among OLT patients.

Abstract
OBJECTIVES Reduced cortical inhibition is a feature of focal hand dystonia and this likely contributes to excessive muscle contractions. Inhibition from the opposite hemisphere, known as interhemispheric inhibition (IHI), was studied bidirectionally in 7 right-handed patients with writer's cramp (WC) and age-matched healthy controls in a cross-sectional physiologic study. METHODS IHI was measured with paired transcranial magnetic stimulation with the conditioning stimulus applied to the motor cortex and the test stimulus applied to the contralateral motor cortex. Surface EMG was measured in right and left first dorsal interosseous muscles during rest, and while holding a pen between the thumb and index finger at 20% maximum voluntary contraction with the right dystonia-affected hand. The time course and magnitude of IHI was studied at interstimulus intervals of 6, 8, 10, 12, 30, 40, and 50 msec between the conditioning stimulus and test stimulus. RESULTS In WC at rest, IHI was significantly reduced in the dystonia-affected right hand (IHI from right to left motor cortex) at both short (SIHI, 10-12 msec) and long (LIHI, 30-40 msec) intervals compared to the unaffected hand. Compared to controls, SIHI and LIHI were reduced in the dystonia-affected hand only. There was no difference in IHI between controls and WC during the task of holding a pen. CONCLUSIONS In WC, both SIHI and LIHI are reduced in the dystonia-affected hand compared to the unaffected hand and to healthy controls. Impaired IHI may contribute to excessive muscle contraction in WC.
