Abstract
Objective: To compare the efficacy and safety of active transfer of plaque (ATP) versus provisional stenting (PS) with drug-eluting stents (DES) for the treatment of coronary bifurcation lesions. Methods: A total of 1 136 patients with bifurcation lesions hospitalized in 6 selected hospitals between January 2010 and January 2014 were included in this prospective observational trial, patients were divided into either ATP (n=560) or PS group (n=576) accordingly. The primary endpoint was target lesion revascularization within 1 year, and the second endpoints were all-cause death, cardiogenic death, myocardial infarction, stent thrombosis, stroke, recurrent angina within 1 year. Results: There were no significant differences in age, sex, hypertension, diabetes, hyperlipidemia and smoking history between the two groups (P>0.05). The incidence of TIMI blood flow <3 grade in the side branch (1.6%(9/560) vs. 7.5% (43/576), P<0.01), acute occlusion of the side branch (1.3%(7/560) vs. 7.1%(41/576), P<0.01) and implanted stents of side branch (1.8%(10/560) vs. 7.8% (45/576), P<0.01) were significantly lower in the ATP group than those in the PS group. During the one year follow up, the rate of target lesion revascularization was similar between ATP group and PS group (4.6%(26/560) vs. 4.0%(23/576), P=0.66). Conclusions: The effectiveness and safetyof ATP techniquein the patients with coronary bifurcation lesions is comparable to the PS technique. However, ATP technique is superior to PS technique on effectively reducing the incidence of implanted stents in the side branch.

Abstract
Mercury emission flows in the global supply chains have evolved into an ever-increasing complex network. However, the underlying structural features remain unknown. Therefore, the global embodied mercury flow network was constructed to reveal the characteristics of energy-induced mercury emissions embodied in international trade at both national and sectoral scales. The small-world nature of the global mercury flows network was identified at both scales. Results showed that the global mercury flow network can be divided into 4 national communities, within which the spillover effects of the interventions in one region spread more easily. Detecting the mercury-intensive supply-chain clusters highlights the importance of monitoring these clusters that dominate mercury emissions in global supply chains, which could offer insights on where policy can be implemented effectively. Moreover, vital regions (e.g., mainland China, the USA, and Germany) and sectors (e.g., Petroleum, Chemical and Non-Metallic Mineral Products, Metal Products and Electrical and Machinery in mainland China) for global mercury control have been unveiled by using an integrated centrality measurement system. Our results highlight that, for the overall mercury reduction, regional and even global collaboration should be enhanced along with efforts in individual regions, and enterprises in these important sectors should invest more to green their cluster-wise supply chains.

Abstract
BACKGROUND Ceramide plays critical roles in cell proliferation, senescence and apoptosis, and is implicated in neurodegenerative diseases, etc. To clarify if ceramide plays some roles in retinal diseases, we established in vivo and in vitro retinal injury models with ceramide 2 (C2) treatment. In addition, Erythropoietin (EPO), which showed protective effects on retinal cells and blood-retinal barrier (BRB), was also tested for its protection and possible mechanism(s) in these models. METHODS Male Sprague-Dawley rats were divided into four groups, i.e., normal control, vehicle control, C2 treatment, and C2+EPO treatment. After intravitreal injection, the rats were examined for eye fundus, electroretinogram, histological study, and immunostaining, etc. In vitro, retinal neuronal cell line (R28) and the primary human retinal microvascular endothelial cells (HRMECs) were treated with C2, cell viability assay, transendothelial electrical resistance (TEER) and BRB-related molecules were studied to test the protective effect of EPO. RESULTS Intravitreal C2-treatment caused significant vision loss in rats, as reflected by reduced b-wave amplitude, increased TUNEL positive cells and GFAP immunostaining in retina. Another major retinal injury observed was BRB breakdown following C2- treatment. Such C2-induced injuries were further confirmed by in vitro study. When HRMECs were treated with C2, the TEER was significantly reduced. The mechanisms for C2 to induce such injuries might be through evidently increased expressions of the related molecules like plasmalemma vesicle-associated protein (PLVAP or PV-1), ecto- 5'-nucleotidase (CD73) and intercellular adhesion molecule-1 (ICAM-1), as observed in C2-treated R28 cells. All these injuries induced by C2 were significantly prevented by EPO both in vivo and in vitro, and its protective mechanisms here might be, in addition to neuroprotective, closely related to its maintenance of BRB integrity, through reducing the expressions of PV-1, CD73 and ICAM-1. CONCLUSION C2 could induce severe retinal injury, and such injuries could be effectively prevented by EPO treatment.

Abstract
Objective: To understand the current status of follow up of people living with HIV/AIDS by health service at grass root in rural area of Jiangxi province and related factors, and provide references for the promotion of the follow up by grass root health service. Methods: People living HIV/AIDS aged ≥18 years and diagnosed before 31 December 2017 in 6 townships of Xinjian, Yushan counties and Guixi city were included in the study in Jiangxi province. They had been followed up for more than one time after the first epidemiologic survey. The information about their demographic characteristics and HIV infection status were collected by using self-designed questionnaire. Univariate and multivariate logistic regression analyses were conducted to identify the factors that influencing the acceptance of follow up by grass root health service. Results: Of the 373 surveyed HIV infected subjects aged (53.06±16.15) years, 261 were males (70.0%, 261/373). Among the surveyed subjects, the illiteracy and people who received only primary school education accounted for 54.7% (204/373). The rate of follow up of the HIV infected subjects by grass root health service was 55.8% (208/373), and those through heterosexual contact were 58.5% (190/325). The multivariate regression analysis showed that the acceptance of follow up by grass root health service was higher in those who were farmers (OR=7.36, 95%CI: 2.52-21.45), had family support (OR=16.01, 95%CI: 2.25-49.73), didn't worry about discrimination (OR=12.97, 95%CI: 4.75-35.42), trusted health care provider (OR=5.07, 95%CI: 2.19-11.76) and showed AIDS symptoms (OR=10.58, 95%CI: 2.25- 49.73). Conclusions: The performance of follow up of people living with HIV/AIDS by grass root health service was well, suggesting it is a feasible management model. Being famer or not, family member supporting or not, worry about discrimination or not, trusting health care provider or not and showing AIDS symptoms or not were the main factors influencing the acceptance of follow up by grass root health service.

Abstract
The first (v_{1}^{fluc}), second (v_{2}), and third (v_{3}) harmonic coefficients of the azimuthal particle distribution at midrapidity are extracted for charged hadrons and studied as a function of transverse momentum (p_{T}) and mean charged particle multiplicity density ⟨N_{ch}⟩ in U+U (sqrt[s_{NN}]=193 GeV), Au+Au, Cu+Au, Cu+Cu, d+Au, and p+Au collisions at sqrt[s_{NN}]=200 GeV with the STAR detector. For the same ⟨N_{ch}⟩, the v_{1}^{fluc} and v_{3} coefficients are observed to be independent of the collision system, while v_{2} exhibits such a scaling only when normalized by the initial-state eccentricity (ϵ_{2}). The data also show that ln(v_{2}/ϵ_{2}) scales linearly with ⟨N_{ch}⟩^{-1/3}. These measurements provide insight into initial-geometry fluctuations and the role of viscous hydrodynamic attenuation on v_{n} from small to large collision systems.

Abstract
Objective: To analyze the safety of endoscopic stapes surgery, and to compare the results with stapes surgery under microscopic approach. Methods: This was a retrospective study. One hundred and thirty seven patients from Eye Ear Nose and Throat Hospital of Fudan University and other seven hospitals were enrolled in this study. Eighty eight patients, in whom 29 were male, and 59 were female, aged from 29 to 66 years old, with an average of 40.1±10.7, underwent endoscopic stapedotomy and 49 patients, in whom 17 were male, and 33 were female, aged from 32 to 64 yeas old, with an arerage of 38.7±9.2, underwent microscopic stapedotomy for otosclerosis. Interventions included endoscopic and microscopic stapes surgeries. Main outcome measures consisted of operating time, preoperative and postoperative hearing, intraoperative findings, and postoperative complications. SPSS 16.0 software was used to analyzed the date (t test and χ(2) test) . Results: Patients in the group who underwent endoscopic stapes surgery showed a mean operative time of (74.1±26.0) min. Patients in the group treated by microscopic approach had a mean operative time (66.5±15.9) min. Statistical difference was evident (t=1.279, P<0.05) . The average operative time of endoscopic surgery became shorter as the cases increased. The average duration of the last 10 cases was shorter than that of the first 10 cases in both groups. The differences were significant (t value was 3.028, 3.610, both P<0.05). No statistical difference was found in air conduction threshold improvement (t=1.074, P=0.289) , air-bone gap closure (t=-0.135, P=0.893) and bone conduction improvement (t=1.222, P=0.228) between the two groups. No difference regarding the incidence of the postoperative complications (chorda tympanum damage: 6 cases vs 2 cases, χ(2)=0.08,P>0.05; vertigo:18 cases vs 9 cases,χ(2)=0.09, P>0.05; facial paralysis: 0 case vs 0 case) between the two groups was found. Conclusion: Audiological outcomes achieved by endoscopic surgery are similar to the results obtained through a microscopic approach. Endoscopic stapes surgery is safe.

Abstract
Colon cancer is a major cause of cancer mortality worldwide and most colon cancers are adenocarcinoma. MicroRNA (miRNA) expression signature has been shown to be able to predict progression and prognosis of various cancers. The aim of our study was to explore a novel signature of microRNA expression for predicting survival of colon adenocarcinoma patients. By analyzing the miRNA expression profiles and clinical information of 329 colon adenocarcinoma patients derived from The Cancer Genome Atlas database. 129 miRNAs were identified to be expressed differentially between the cancer and adjacent tissues. Among them, 27 miRNAs were found to be associated with the corresponding clinical characteristics of the patients. Furthermore, 7 miRNAs (let-7a-2, mir-32, mir-181a-1, mir-197, mir-328, mir-505 and mir-652) were found to be significantly correlated with the patient survival. The risk established by the 7-miRNA signature we built was proved be an independent prognostic factor (Hazard ratio [HR] = 2.048; 95% CI = 1.144-3.664; p, 0.016). In summary, our study identified miRNAs correlated with progression and prognosis of colon adenocarcinoma and built a 7-microRNA expression signature for prediction of the survival of the patients with colon adenocarcinoma.

Abstract
Disfunction of Eustachian tube will cause negative pressure of middle ear, which may result in tympanic membrane retraction pocket. Severe pocket can consequently cause cholesteatoma. In clinical practice it is not uncommon to find a cholesteatoma limited to epitympanum, with an otherwise normal pars tensa and mesotympanum. This review explains the theory of "selective epitympanic dysventilation syndrome" developed by endoscopic technique. In the majority of the patients, the only ventilation pathway to the epitympanum is through the tympanic isthmus. Even if Eustachian tube function has recovered, an isthmus blockage with selective epitympanic dysventilation may lead to common attic cholesteatoma.

Abstract
Oxaloacetate (OA) is one of the intermediates of the Krebs cycle. In addition to its role in energy production, OA may have other effects on the cell. We report here that OA could have a cell type dependent cytotoxic effect on the human hepatic carcinoma cell line HepG2 through induction of apoptosis and reactive oxygen species (ROS) accumulation. In our study, OA decreased the viability and colony formation of HepG2 cells and induced cell death. Caspase-3 activity was increased, the pro-apoptotic protein Bax was up-regulated, and the anti-apoptotic protein Bcl-2 was down-regulated in OA-treated HepG2 cells indicating that apoptosis through the intrinsic pathway was involved in the cell death. The ROS level in OA-treated HepG2 cells was increased. The anti-oxidant N-acetylcysteine (NAC) and glutathione (GSH) prevented the OA-induced decrease in cell but did not alter the enhanced apoptotic Bax/Bcl-2 mRNA ratio. These results suggest that the OA-induced apoptosis of HepG2 cell is not driven by oxidative damage and at least two distinct mechanisms, one mediated by ROS and one involving apoptosis, result in the cytotoxic effects of OA on HepG2 cells. These studies expand the biological functional repertoire of OA and provide a mechanism by which hepatocellular carcinoma may be targeted by OA.

Abstract
Background Isoflurane preconditioning (IPC) induces cerebral ischaemic tolerance, but the mechanism remains poorly understood. The aim of this study was to determine changes in mitochondrial function in the brain after IPC, and whether the cannabinoid receptor 1 (CB1R) could be involved in the mechanism of mitochondrial protection mediated by IPC. Methods Adult male Sprague-Dawley rats were pretreated with isoflurane 2% for 1 h day -1 , for 5 days consecutively, and then subjected to 120 min right middle cerebral artery occlusion. Cannabinoid receptor 1 expression in the cellular and mitochondrial membrane was measured. The CB1R agonist HU-210 was administered alone, or the antagonists AM251 and SR141716A were given to the animals before each preconditioning. Neurological scores, infarct volume, apoptosis, and mitochondrial function were examined after middle cerebral artery occlusion. Results Expression of CB1R on cellular and mitochondrial membranes was increased 6 h after preconditioning. Both IPC and HU-210 administration before middle cerebral artery occlusion improved neurological outcomes and reduced infarct volume. Isoflurane preconditioning increased the expression of the anti-apoptotic proteins Bcl-2 and Bcl-X L and reduced apoptosis in neurones. Isoflurane preconditioning and HU-210 also markedly preserved the activity of respiratory chain complexes, reduced mitochondrial radical generation, preserved mitochondrial membrane potential, and inhibited mitochondrial permeability transition pore opening. Cannabinoid receptor 1 antagonists abolished the improvement in mitochondrial function and the neuroprotective effects induced by IPC. Conclusions Our results indicate that IPC elicits brain ischaemic tolerance and mitochondrial protection by activating the CB1R, which provides a new mechanism for IPC-induced neuroprotection against cerebral ischaemia.

Abstract
Objective: To explore the efficacy of ossiculoplasty surgery under oto-endoscope in patients of conductive hearing loss with intact tympanic membrane. Methods: A retrospective study was conducted. The clinical data of 45 patients with conductive hearing loss who had undergone simple ossiculoplasty surgery between October 2015 and December 2017 from five hospitals in China (West China Hospital of Sichuan University, General Hospital of the People's Liberation Army, Shanghai Ninth People's Hospital, Shanghai JiaoTong University School of Medicine, Xijing Hospital, Fourth Military Medical University and Shenzhen Sixth People's Hospital) were collected. There were 28 males and 17 females, with the age ranging from 12 to 69 years old. The tympanic membranes of those patients were intact before surgery. The lesion only occurred in the ossicular chain from CT and intraoperative exploration. The cases of otosclerosis, tympanosclerosis, cholesteatoma of middle ear, chronic suppurative otitis media, and tumor of middle ear were excluded. The postoperative complications, hearing improvements and operation time were observed. SPSS 23.0 software was used for statistic analysis. Results: There was neither sensorineural hearing loss nor facial paralysis after surgery in this group. Seven patients had transient mild tinnitus after surgery and gradually relieved during the follow-up period. Nine patients developed dysgeusia after surgery. Two patients developed dizziness after surgery, and the symptoms were mild and relieved during 1 week without special intervention. The air-bone gap (ABG) range of pre-operation was 22.5-45.7 dB, and the average ABG was (25.3±8.6) dB. The ABG range in the third month after surgery was 5.7-26.8 dB, and the average ABG was (9.3±8.6) dB. The mean value of ABG was significantly lower in the third month after surgery compared with that of pre-operation (t=2.31, P<0.05). The operation time of the surgeons in each research center was similar. The overall average of operation time was (43.56±18.25) min. There was no significant difference in the duration of operation between the centers (F=3.26, P>0.05). Conclusion: The ossiculoplasty surgery under oto-endoscope has good efficacy.

Abstract
Objective: To analyze the therapeutic effect of endoscopic myringoplasty. Methods: A retrospective analysis of 523 patients with chronic otitis media who underwent endoscopic myringoplasty between June 2016 and June 2017 in eight tertiary hospitals in China. Among all the patients, 256 were male and 267 were female, aged from 18 to 68 years old. The grafts used to repair the tympanic membrane were all tragus cartilage-perichondrium complex. All patients were followed up at 1 month, 3 months, 6 months, 9 months, and 12 months after surgery, at least 3 months. The closure rate of tympanic membrane perforation by different factors, the hearing results, and the incidence of postoperative complications were analyzed. SPSS 21.0 software was used to analyze the data. Results: Three months after operation, the closure rates of anterior, inferior, posterior and subtotal perforation were 92.4% (109/118), 94.9% (93/98), 95.6% (129/135), and 89.0% (153/172) respectively, the difference was not statistically significant (χ(2)=5.779, P=0.123). The closure rates of small, medium and large perforations were 100.0% (82/82), 93.7% (178/190) and 89.2% (224/251) respectively. The difference was statistically significant (χ(2)=10.927, P=0.004). The closure rates of dry ear and wet ear tympanic membrane perforation were 93.1% (392/421), 90.2% (92/102), the difference was not statistically significant (χ(2)=1.011, P=0.915). The preoperative pure tone audiometry(PTA) was (38.4±5.3) dBHL, while, the 3-month postoperative PTA was (25.1±5.7) dBHL. The difference was statistically significant (t=39.079, P<0.001). The preoperative air bone gap (ABG) was (22.4±4.3) dB, while 3 months postoperative ABG was (9.1±3.8) dB. The difference was statistically significant (t=53.004, P<0.001). Of all 523 patients, 14 (2.7%) had middle ear infection, 8 (1.5%) had dislocated tympanic membrane, 12 (2.3%) had parageusia, 35 (6.7%) had tinnitus, 28 (5.4%) had hearing loss, 26 (5.0%) had vertigo,33 (6.3%) had reperforation, 2 (0.4%) had secondary cholesteatoma, and none had facioplegia. Conclusions: Endoscopic myringoplasty is a safe and effective surgical method with good postoperative outcome.

Abstract
With the rapid development of modern equipment and widespread familiarity with the relative knowledge, endoscopic ear surgery has attracted many oto-surgeons and is becoming more popular in primary hospitals in China. Standardized management of perioperative period in this field can help surgeons shorten the learning curve and avoid potential complications in endoscopic ear surgery. In this article, the management technique was introduced in detail, covering five main aspects including handling of related in-struments, preoperative examination and preparation, informed consent, preparation for patients and operation room setup. Extra focus was placed on the manipulation and resolution of possible difficulties during the procedure.

Abstract
Objective: To explore the effect of Src on cervical cancer cells through ERK signal transduction pathway. Methods: Experimental study was carried out in vitro. Cervical cancer cell lines Hela (HPV-positive) and C33A (HPV-negative) were treated with Src kinase inhibitor PP2. Then, the cell cycle and apoptosis of each group were evaluated by using flow cytometry (FCM). Western blotting and Real-time PCR were used to detect the levels of the expression of ERK 1/2, c-Fos and c-Jun mRNA and protein respectively. The database was established and analyzed with SPSS statistical software (version 20.0). Results: After down-regulating Src, the cell proliferation was inhibited and cell apoptosis was induced. The proportions of G0/G1 stage of Hela and C33A cell in cell cycle increased while G2/M and S stages decreased. Meanwhile, the mRNA levels of ERK 1, ERK 2, c-Fos and c-Jun increased. And the expression levels of ERK 1/2, phosphorylated ERK 1/2 (p-ERK 1/2) and phosphorylated c-Fos (p-c-Fos) protein decreased, while c-Jun and phosphorylated c-Jun (p-c-Jun) protein expression increased. In addtion, the change level of Hela cell, p-ERK 1/2 and c-Fos protein were lower than that of C33A cell before and after the Src inhibition. Conclusions: Src, involved in regulating the expression of key factors of the ERK signal transduction pathway including p-ERK 1/2 and p-c-Fos, might be capable of promoting the proliferation of cervical cancer cells and inhibiting their apoptosis. The infection with HPV might have adjustable effect on this process.

Abstract
Duck Tembusu virus (DTMUV) is a newly emerging enveloped flavivirus. This study shows the ultrastructure of DTMUV using viral purification, negative staining and electron microscopy. Electron microscopic examinations revealed mature DTMUV particles with 50 to 75 nm in diameter and typical enveloped flavivirus structure that consists of the internal nucleocapsid, an inner layer of lipid bilayer and an external layer of E glycoprotein ectodomain. Particles appear to be mostly spherical. In particular, RNA core is deep colored and dense, both capsid and lipid bilayer are clearly visible, the capsid forms regular hexagon, and E glycoprotein ectodomain forms a fringe instead of visible spikes. Thus, this report about the clear ultrastructure of the DTMUV particles will be the major driving forces behind structural biology of DTMUV.

Abstract
Objective: To investigate the effect of long-term deep slow-wave sleep deprivation on the gonad axis, sperm abnormality rate, and structure of the testis in male rats and possible mechanisms. Methods: A total of 30 specific pathogen-free male Wistar rats aged 5 weeks were randomly divided into slow-wave sleep deprivation group 1 (SD1 group) , slow-wave sleep and sleep time deprivation group 2 (SD2 group) , and control group, with 10 rats in each group. The flower pot method was used to establish a model of sleep deprivation. In addition to 12-hour sleep deprivation at night, the rats in the SD1 group were given interference once every 24 minutes, and those in the SD2 group were deprived of sleep for 8 minutes every 24 minutes; the rats in the control group were given 12-hour light illumination and then placed in dark environment for 12 hours. All rats were sacrificed by exsanguination from the femoral artery, and the testis, the epididymis, and blood were collected for analysis. Sperm abnormality rate and sperm motility rate were measured, and cauda epididymal sperm counting was performed. ELISA was used to measure the serum levels of testosterone (T) , follicle-stimulating hormone (FSH) , and luteinizing hormone (LH) . Results: Compared with the control group, the SD2 group had a significant increase in organ coefficient of the epididymis (P<0.05) and a significant reduction in sperm motility rate (P<0.05) . There were significant differences between the SD1 group and the SD2 group in the increase in sperm abnormality rate (P<0.05) and the reduction in cauda epididymal sperm count (P<0.05) . The levels of FSH and T tended to increase, and the level of LH tended to decrease. Pathological examination showed degeneration and vacuolization of a small amount of spermatogenic cells in the SD1 group; in the SD2 group, there were significant degeneration, edema, and vacuolization of most spermatogenic cells, some spermatogenic cells were observed in the lumen, and there were no sperms in the lumen. Conclusion: Long-term deep slow-wave sleep deprivation impairs the structure of the testis, affects sperm motility rate and sex hormones, and increases the risk of sperm abnormality.

Abstract
OBJECTIVE Vascular invasion is observed at the osteochondral junction in osteoarthritis (OA). Nerve growth factor (NGF) as an angiogenic factor is expressed in OA. This study is to investigate the effects of NGF on angiogenesis in vitro in human chondrocytes. DESIGN Articular cartilages of knee joints were harvested from healthy and OA patients. Expressions of NGF and tropomyosin-related kinase A (TrkA) were detected by western blot, Safranin-O and fast green staining and immunohistochemistry in cartilage. Expression of fibroblast growth factor 2 (FGF2) was detected by western blot in cultured chondrocytes. Chondrocytes were transfected by lentiviral vectors to knock down TrkA. Migration and tube formation of human microvascular endothelial cell (HMVEC) were assessed by using transwell co-culture with chondrocyte after treatment of NGF. RESULTS We confirmed expressions of NGF and TrkA were significantly up-regulated in OA. NGF induced expression of FGF2 in a time- and dose-dependent manner. Angiogenic activities of endothelial cells were greatly enhanced after co-cultured with NGF pre-treated chondrocytes, while knock-down of TrkA significantly abolished the above effects. We further found that NGF-induced expression of FGF2 promoted angiogenic activities of endothelial cells through PI3K/Akt and ERK/MAPK signaling pathways. CONCLUSIONS NGF promotes expression of FGF2 in vitro via PI3K/Akt and ERK/MAPK signaling pathways in human chondrocytes and it increases angiogenesis, which is mediated by TrkA. NGF could be responsible for vascular up-growth from subchondral bone in OA.

Abstract
Objective: To understand the prevalence of hepatitis C virus (HCV) infection in 5 populations in China during 2016-2017 and provide evidence for the estimation of prevalence trend of hepatitis C and evaluation on the prevention and control effect. Methods: A total of 87 national sentinel surveillance sites for hepatitis C were set up in 31 provinces (autonomous regions and municipalities) of China to obtain the information about HCV infection prevalence in 5 populations, including volunteer blood donors, people receiving physical examination, patients receiving invasive diagnosis and treatment, patients receiving hemodialysis, and clients visiting family planning outpatient clinics. From April to June, 2016 and 2017, cross-sectional surveys were repeatedly conducted in the 5 populations and blood samples were collected from them for HCV antibody detection. Results: In 2016, 86 sentinel sites completed the surveillance (one sentinel site was not investigated), and 115 841 persons were surveyed. The overall HCV positive rate was 0.38% (442/115 841, 95%CI: 0.23%-0.53%). In 2017, all the 87 sentinel sites completed the surveillance, and 120 486 persons were surveyed. The overall HCV positive rate was 0.37% (449/120 486, 95%CI: 0.23%-0.52%). In 2016 and 2017, the anti-HCV positive rates were 4.46% (223/5 005, 95%CI: 2.18%-6.73%) and 4.39% (216/4 919, 95%CI: 2.29%-6.50%) respectively in hemodialysis patients, 0.85% (44/5 200, 95%CI: 0.27%-1.42%) and 0.70% (36/5 150, 95%CI: 0.15%-1.24%) respectively in patients receiving invasive diagnosis and treatment and remained to be ≤0.25% in volunteer blood donors, people receiving physical examination and clients visiting family planning outpatient clinics. Results for the comparison of the anti-HCV positive rates in the 5 populations indicated that the differences were significant (F=23.091, P<0.001 in 2016 and F=20.181, P<0.001 in 2017). Conclusions: Data from the sentinel surveillance of HCV infection on prevalence in China showed that the anti-HCV positive rates varied in the 5 populations during 2016-2017. The anti-HCV positive rate appeared the highest in the hemodialysis patients, followed by that in the patients receiving invasive diagnosis and treatment, and the prevalence of HCV infection in other 3 populations were at low levels.

Abstract
Objective: To explore the biomarkers that applied to pulmonary acute respiratory distress syndrome (ARDS) and extrapulmonary ARDS respectively. Methods: A total of 49 eligible patients with ARDS were selected from Department of Respiratory intensive care unite (ICU) , Department of General ICU and Department of Emergency ICU, the Second Affiliated Hospital of Nanchang University, during April 2015 and February 2016, and divided into pulmonary ARDS group (n=26) and extrapulmonary ARDS group (n=23) according to primary causes. Totally 19 cases from healthy examination personnel were served as control. Acute physiology and chronic health evaluation Ⅲ (APACHE Ⅲ) score and lung injury score of all hospitalized patients were completed within 24 hours after the diagnosis of ARDS and the serum levels of angiogenin2 (Ang-2) , surfactant protein D (SP-D), soluble receptor for advanced glycation end products (sRAGE), Krebs von den Lungen-6 (KL-6) were measured. Then the 28-day outcomes were observed. The serum levels of the biomarkers were compared between each group and correlation analysis was conducted between different indexes. Finally, The relationship between the four biomarkers and the outcome of each group was analyzed. Results: The serum level of Ang-2 in pulmonary ARDS group and extrapulmonary ARDS group was significantly higher than that in control group[1 462 (569, 3 638) and 4 568 (2 236, 8 457) vs 460 (389, 578) ng/L, all P<0.05], and the serum level of Ang-2 was significantly higher in extrapulmonary ARDS group than that in pulmonary ARDS group (P<0.05). The serum level of SP-D in pulmonary ARDS group and extrapulmonary ARDS group was significantly higher than that in control group[5.9 (2.5, 22.7) mg/L and 3.7 (1.7, 6.5) vs 1.9 (0.6, 4.4) mg/L, all P<0.05], and the serum level of SP-D was significantly higher in pulmonary ARDS group than that in extrapulmonary ARDS group (P<0.05). The serum level of sRAGE in pulmonary ARDS group and extrapulmonary ARDS group was significantly higher than that in control group[238 (101, 583) and 229 (114, 443) vs 117 (88, 176) ng/L, all P<0.05]. The serum level of KL-6 in pulmonary ARDS group was significantly higher than that in control group[10 435 (3 401, 17 607) vs 4 780 (3 962, 5 320) U/L, P<0.05]. Increased serum levels of SP-D (OR=1.089, 95% CI: 1.001-1.085) and KL-6 (OR=1.206, 95% CI: 1.016-1.432) at the early stage were the independent prognostic factors for the 28-day mortality for pulmonary ARDS. Advanced age (OR=2.622, 95% CI: 1.046-6.574) was the independent prognostic factor for the 28-day mortality for extrapulmonary ARDS. Conclusion: SP-D and KL-6 may be the serum biomarkers of pulmonary ARDS and Ang-2 may be the serum biomarker of extrapulmonary ARDS.

Abstract
AIM To determine the enhanced computed tomography (CT) and magnetic resonance imaging (MRI) characteristics of combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) in Chinese patients. MATERIALS AND METHODS Patients with histopathologically proven cHCC-CC (n=54) were compared with hepatocellular carcinoma (HCC; n=41) and cholangiocellular carcinoma (CCC; n=41) patients. Clinical information was measured in all patients. Tumour size, tumour margins, signs of cirrhosis, pseudocapsule, capsular retraction, rim enhancement, intrahepatic biliary dilatation, portal vein thrombosis, upper abdominal lymphadenopathy, were assessed on CT and/or MRI. The dynamic pattern of enhancement was also assessed. RESULTS The majority (81.5%) of cHCC-CC patients had positive hepatitis B serology. The presence of cirrhosis and tumour blood vessels was comparable in cHCC-CC and HCC, but significantly lower in CCC (p>0.05). The presence of ill-defined margin and regional lymphadenopathy was comparable in cHCC-CC and CCC, but significantly lower in HCC (p>0.05). The pseudocapsule, capsular retraction, biliary dilatation, rim enhancement, and abnormal perfusion were significantly different between the three types of lesions, with cHCC-CC being intermediate between HCC and CCC. Nearly half of the cHCC-CC tumours (25; 46.3%) showed the wash-in and wash-out enhancement pattern; the gradual, persistent, and mixed patterns were seen in 12 (22.2%), 5 (9.3%), and 12 (22.2%) tumours, respectively. CONCLUSION The majority of cHCC-CC tumours occur against a background of positive hepatitis B serology and cirrhosis. Imaging findings vary widely between cHCC-CC tumours. In the present series, the enhancement pattern of cHCC-CC tumours was HCC-like in most cases.

Abstract
Objective: To investigate the interventional effect of bicyclol on isoniazid-induced liver injury in rats and the expression of endoplasmic reticulum stress (ERS) protein, glucose regulatory protein 78 (GRP78), and growth arrest and DNA-damage-inducible gene 153(CHOP). Methods: Eighty Wistar rats were randomly divided into control group (8 rats) and model group (72 rats). After 10 days of intragastric administration of isoniazid, the model group rats were randomly divided into treatment group (A), natural recovery group (B), etiological persistence group (C) and etiological persistence plus treatment group (D). Sixteen rats from each group were sacrificed after 1 and 2 weeks of intervention with different methods. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected. Liver pathological morphology was observed. Apoptotic cells were detected by TUNEL assay. ERS protein expression was detected by Western blot. A t-test or randomized block analysis of variance, K-S test and Levene's test were used to analyze the normality and homogeneity of variance. Kruskal-Wallis rank sum test was used for data that did not suit the conditions of t-test and variance analysis. Results: ALT and AST were elevated in the model group, and liver pathological examination showed liver tissue damage. Apoptotic index was higher than control group (7.13% ± 1.55% vs. 0.75% ± 0.71%, Z = -3.411, P < 0.01), and the expression value of ERS protein in model group was significantly higher than control group (GRP78: 1.16 ± 0.30 vs. 0.23 ± 0.05, t = -6.008, P < 0.01; CHOP: 0.98±0.23 vs. 0.20 ± 0.10, t = -6.378, P < 0.01). Serum enzymes, apoptotic index and ERS protein expressions of rats were decreased after treatment with bicyclol, and the pathological damage was eased. Rats in natural recovery group recovered less than the treatment group. Conclusion: Isoniazid-induced liver injury is associated to ERS-related excessive apoptosis and the therapeutic effect of bicyclol on drug-induced liver injury may minimize ERS-induced apoptosis.

Abstract
Objectives Test the performance of topical antimicrobial wound solutions against microbial biofilms using in vitro, ex vivo and in vivo model systems at clinically relevant exposure times. Methods Topical antimicrobial wound solutions were tested under three different conditions: (in vitro) 4% w/v Melaleuca oil, polyhexamethylene biguanide, chlorhexidine, povidone iodine and hypochlorous acid were tested at short duration exposure times for 15 min against 3 day mature biofilms of Staphylococcus aureus and Pseudomonas aeruginosa; (ex vivo) hypochlorous acid was tested in a porcine skin explant model with 12 cycles of 10 min exposure, over 24 h, against 3 day mature P. aeruginosa biofilms; and (in vivo) 4% w/v Melaleuca oil was applied for 15 min exposure, daily, for 7 days, in 10 patients with chronic non-healing diabetic foot ulcers complicated by biofilm. Results In vitro assessment demonstrated variable efficacy in reducing biofilms ranging from 0.5 log10 reductions to full eradication. Repeated instillation of hypochlorous acid in a porcine model achieved <1 log10 reduction (0.77 log10, P = 0.1). Application of 4% w/v Melaleuca oil in vivo resulted in no change to the total microbial load of diabetic foot ulcers complicated by biofilm (median log10 microbial load pre-treatment = 4.9 log10 versus 4.8 log10, P = 0.43). Conclusions Short durations of exposure to topical antimicrobial wound solutions commonly utilized by clinicians are ineffective against microbial biofilms, particularly when used in vivo. Wound solutions should not be used as a sole therapy and clinicians should consider multifaceted strategies that include sharp debridement as the gold standard.

Abstract
OBJECTIVES To evaluate the performance of QuantiFERON-TB Gold Plus (QFT-Plus) on Mycobacterium tuberculosis (MTB) infection test among registered village doctors from China. METHODS MTB infection of the registered village doctors in Zhongmu County were tested using QFT-Plus and two other interferon-gamma release assays (IGRAs) in parallel: QuantiFERON-TB Gold In-Tube (QFT) and T-SPOT.TB (T-SPOT). Retests were carried out for baseline positives at 3 and 6 months later, respectively. RESULTS A total of 616 village doctors were included in the baseline examination. The positivity of QFT, QFT-Plus and T-SPOT was 27.91% (168/602), 31.22% (187/599) and 27.70% (169/610), respectively. The concordance between QFT and QFT-Plus was 94.81% (Kappa coefficient: 0.87) and between T-SPOT and QFT-Plus was 88.93% (Kappa coefficient: 0.73). Reversions were frequently observed for all three assays. With respect to QFT-Plus, the quantitative results of reversions in the serial testing were mostly distributed in an "uncertain range" zone (0.2-0.7 IU/mL). Similar patterns of distribution were observed for QFT and T-SPOT as well. CONCLUSION Village doctors should gain more attention as an at-risk group for TB infection control in rural China. Our results support, by means of serial testing, a good agreement between QFT-Plus and QFT in Chinese population.

Abstract
Objective: To explore the efficacy of Jinghuaweikang capsules combined with Quadruple therapy in the treatment of Helicobacter pylori (H.pylori)infection. Methods: Patients who were infected with H.pylori in 7 centers in Gansu Province were recruited in this prospective simple randomized study. All the patients are divided into four groups randomly: patients in Group A1 were treated with esomeprazole (20 mg, twice a day) + pectin bismuth (200 mg, three times a day) + amoxicillin (1 000 mg, twice a day) + clarithromycin (500 mg, twice a day), while Group A2 with Jinghuaweikang capsules(160 mg, three times a day) based on group A2, Group B1 with esomeprazole (20 mg, twice a day) + bismuth pectin (200 mg, three times a day) + amoxicillin (1 000 mg, twice a day) + furazolidone (100 mg, twice a day) and Group B2 with Jinghuaweikang capsules(160 mg, three times a day) based on group B2. The treatment time was 14 days for all 4 groups. In the course of treatment, abdominal pain, acid reflux, abdominal distension, belching, hiccups were observed at the time before treatment, 14 days and 30 days after treatment and were scored. Finally, all patients received (13)C or (14)C for H.pylori at the time of 30 days after the treatment. Result: A total of 455 patients were included in 7 hospitals from February 2016 to May 2017 in Gansu province, and there were 189 male patients. Group A1 included 129 cases, group A2 96 cases, group B1 112 cases and group B2 118 cases. The eradication rates that accorded with program data analysis (PP) were A1[46.9%(60/128)], A2[63.8%(60/94)], B1[60.7%(68/112)], B2[68.6%(81/118)] (P<0.004). Compared with group A1, the eradication rate of H.pylori in group B1 and group A2 increased (P<0.001, P=0.032), there was no statistical difference between group B2 and group A2, group B1 and group B2 (P=0.208, P=0.461). According to intentional analysis (ITT), the eradication rates of H.pylori in group A1 were 46.5% (60/129),group A2 were 62.5% (60/96),group B1 were 60.7% (68/112),and group B2 were 68.6% (81/118).The radical rate of A2 was higher than A1 (P=0.017), group B2 was not higher than group B1 (P=0.208), and there was no significant difference among the other groups. The symptoms of abdominal pain, abdominal distention, acid reflux, belching and hiccup in the group A2 and group B2 were improved than those in group A1 and group B1 (P<0.05). No serious adverse reactions occurred in all groups. Conclusion: Jinghuaweikang capsules can improve the eradication rate of Helicobacter pylori, and improve the symptoms of patients.

Abstract
It has long been an aspirational goal to create artificial structures that allow fast permeation of water but reject even the smallest hydrated ions, replicating the feat achieved by nature in protein channels (e.g., aquaporins). Despite recent progress in creating nanoscale pores and capillaries, these structures still remain distinctly larger than protein channels. We report capillaries made by effectively extracting one atomic plane from bulk crystals, which leaves a two-dimensional slit of a few angstroms in height. Water moves through these capillaries with little resistance, whereas no permeation could be detected even for such small ions as Na+and Cl−. Only protons (H+) can diffuse through monolayer water inside the capillaries. These observations improve our understanding of molecular transport at the atomic scale.

Abstract
Objective: To investigate the effect of heterogeneous nuclear ribonucleoprotein K (hnRNP K) and its interaction with human papillomavirus 16 (HPV16) on cervical intraepithelial neoplasia (CIN). Methods: The participants included 67 women with normal cervix (NC), 69 women with CINⅠ and 68 women with CINⅡ/Ⅲ in a community cohort of pathologically diagnosed women established in Jiexiu of Shanxi province, from June 2014 to June 2015. A structured questionnaire was used to collect the demographic data of the subjects and the related factors of cervical lesions. Cervical exfoliated cells and cervical tissues from biopsy or surgery were selected. The infection status of HPV16 was detected by flow-through hybridization. The protein expression levels of hnRNP K were evaluated by Western blot. SPSS 23.0 software was used to collate and analyze the data. To study the differences in demographic characteristics, related factors, hnRNP K protein and HPV16 infection among NC, CINⅠand CINⅡ/Ⅲgroups, χ(2) test, trend χ(2) test, and Kruskal-Wallis H test were conducted. Multiple comparisons of hnRNP K protein in three groups were completed by using the Bonferroni method. The OR and its 95%CI of hnRNP K, HPV16 and CIN were calculated by using the unconditional logistic regression models. Two-way interactions between hnRNP K protein and HPV16 infection on CIN were analyzed by using additive model and related indicators. Results: HPV16 infection rates were 10.4% in women with normal cervix, 14.5% in women with CINⅠ and 41.2% in women with CINⅡ/Ⅲ, respectively. The differences among three groups were significant (P<0.001). Moreover, the infection rates of HPV16 gradually increased with the increasing severity of CIN (trend χ(2)=18.512, P<0.001). The differences in protein expression of hnRNP K among three groups were significant (H=48.138, P<0.001) and the expressionincreased with the development of cervical lesionss (trend χ(2)=21.765, P<0.001). Results from the interaction analysis indicated that there were additive effects between high expression of hnRNP K protein and HPV16 in CINⅡ/Ⅲ group compared with normal group (API=0.639, 95%CI: 0.083-1.196). In contrast, no such additive effect was found in CINⅠ group. Conclusions: HPV16 infection and over-expression of hnRNP K protein were associated with the increased risk of cervical intraepithelial neoplasia. There might be interaction between hnRNP K protein overexpression and HPV16 infection existed on the progress of CINⅡ/Ⅲ.

Abstract
Viral hepatitis is a major public health concern in China, but data on national epidemiological characteristics are lacking. We collected reporting incidence data on hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in China from 2004 to 2014. Empirical mode decomposition (EMD) was performed to accurately describe the reporting incidence trends of HBV and HCV. A mathematical model was used to estimate the relative change in incidence across provinces and age groups. Nationwide, a total of 916 426 hepatitis B cases and 39 381 hepatitis C cases were recorded in 2004; the reporting incidences of HBV and HCV were 70.50/100 000 and 3.03/100 000, respectively. The overall relative changes in HBV and HCV reporting incidences in China from 2004 to 2014 were 0.98 (95% CI 0.96-1.00, P = .082) and 1.16 (95% CI 1.12-1.20, P < .001), respectively. Thirteen provinces experienced decline in HBV reporting incidence. Most provinces exhibited an increasing trend in HCV reporting incidence. People aged ≤24 displayed a significant descending trend in HBV reporting incidence; people aged ≥55 exhibited a significant increasing trend. For HCV infection, the reporting incidence increased in all age groups except the 10-14 age group. In China, the majority of provinces have experienced decline or remained stable in HBV infection but show significant increases in HCV infection. Children and adolescents are well protected from HBV infection, while relatively higher increasing rates are found among older people. HCV is much more prevalent among older people, although its emergence has shifted to younger age groups.

Abstract
Goose parvovirus (GPV) is a highly contagious and lethal disease in goslings and Muscovy ducklings, and is of concern to the waterfowl industry. With the aim of comparing the cellular immunogenicity of three capsid proteins of GPV, plasmids of pcDNA3.1(+)-VP1, pcDNA3.1(+)-VP2, and pcDNA3.1(+)-VP3 were constructed, and the recombinant protein VPs were expressed using an eukaryotic expression system. We detected the levels of immune-related genes (CD4, CD8α, IL-1β, IL-6, IFNα, IFNγ, and IFNλ) in both goose embryo fibroblasts (GEF) and goose peripheral blood mononuclear cells (PBMCs) cellular models. The immune response conferred by a VP2 DNA vaccine in vivo was observed in a time course. Our data suggested that the cellular immune response to VP2 and VP3 was stronger than that to VP1, while VP2 and VP3 shared similar cellular immune reactivity. In addition, vaccination with VP2 plasmid can induce high level of IgY antibody that continued to increase through 28 days post vaccination. Therefore, our findings shed light on the host cellular immune response against GPV capsid proteins. Keywords: GPV; capsid proteins; cellular immune response; humoral immunity.

Abstract
Biodegradable spun-bonded non-woven fabric slices of poly lactic acid (PLA)/polypropylene (PP) were prepared by melt blending. The influence of the proportion of raw materials, blending temperature, blending time and rotation speed on the mechanical properties and melt flow properties of the slices were investigated, the influence of the proportion of PLA and PP composite slices on the thermal properties and microstructure was also researched. According to the research results of optimization conditions, the biodegradable spun-bonded non-woven fabric slice of PLA/PP was prepared and its biodegradable performance was evaluated. The results showed that when (m)PLA : (m)PP was 8 : 2, blending temperature was 185 °C, blending time was 4 min and rotation speed was 50 min−1, the melt blending condition of PLA/PP composite slices was optimal. With the increase of PP mass fraction in slices, slices of melt flow rate (MFR) and glass transition temperature (Tg) were on the decline; T−50 %, T−95 % and TP were on the rise; the crystallinity of PLA/PP slices was increased; SEM results showed that the slices had “sea-island” structure. When (m)PLA: (m)PP was 8 : 2, microorganisms on the slices surface were second level of growth after 28 days which showed that the slices has a good biodegradable performance.

Abstract
Objective: To assess the incidence and characteristics of thyroid dysfunction during anti-Programmed cell death 1 receptor (PD-1) antibody SHR-1210 therapy in patients with advanced solid tumor. Methods: The medical records of 98 patients who initiated SHR-1210 treatment between April 27, 2016 and June 8, 2017 in the phase 1 trial to evaluate the safety, efficacy, and pharmacokinetics of SHR-1210 in patients with advanced solid tumors were retrospectively reviewed. Serological tests of thyroid stimulating hormone (TSH) and free thyroxine (fT4) were measured at baseline and prior to each SHR-1210 administration. Results: A total of 86 patients had normal thyroid function before the first dose of SHR-1210 treatment. Nine out of 86 (10.5%) patients developed new onset hypothyroidism from euthyroid state. 12 patients presented thyroid dysfunction at baseline, 10 of whom were subclinical hypothyroid and 2 were hypothyroidism. Four out of 10 patients developed hypothyroidism from subclinical hypothyroid. Most patients with hypothyroidism were asymptomatic. Thyroid dysfunction occurred early (median, 55days) after the initiation of SHR-1210. The severity of hypothyroidism were all grade 1-2. No grade 3-4 hypothyroidism occurred. No patients discontinue the treatment of SHR-1210 due to clinical impact of the thyroid dysfunctions. Conclusions: Thyroid-related adverse events were common during anti-PD-1 antibody SHR-1210 treatment . The incidence of hypothyroidism is lower in patients with euthyroid state than in patients with thyroid dysfunction at baseline during SHR-1210 treatment . Thyroid function can be improved after thyroid hormone replacement. During SHR-1210 treatment, it is necessary to pay attention to monitor the thyroid function, especially in the patients with thyroid dysfunction at baseline. Trial registration: Chinese Clinical Trial Registry, 2016L01455.

Abstract
OBJECTIVE The objective of this article is to investigate whether the aberrant expression of collagen triple helix repeat containing-1 (CTHRC1) from patients with systemic lupus erythematosus (SLE) could contribute to the pathogenesis of lupus. METHODS We divided SLE patients into active groups (Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score ≥ 6) and inactive groups (SLEDAI score < 6). Serum concentrations of CTHRC1, interferon alpha, interleukin (IL)-28A and IL-28B were determined using an enzyme-linked immunosorbent assay in a group of 40 patients with SLE. Results were compared with those from 23 healthy controls. RESULTS Serum CTHRC1 protein levels were higher in patients with SLE compared with healthy controls. Patients with active disease displayed higher CTHRC1 levels compared with those with inactive disease as well. There was a positive association between serum CTHRC1 levels and SLEDAI and erythrocyte sedimentation rate, and a negative correlation with complement 3 and 4. Moreover, serum CTHRC1 levels were higher in SLE patients with arthritis and anemia compared with patients without the above-mentioned manifestations. CONCLUSIONS These findings indicate CTHRC1 probably plays an important part in the pathogenesis of SLE, and is positively associated with disease activity, while it also likely refers to the development of arthritis and anemia in SLE. Therefore, CTHRC1 may provide a novel research target and shed new light on the pathogenesis and therapy of SLE.

Abstract
We report first measurements of e^{+}e^{-} pair production in the mass region 0.4<M_{ee}<2.6 GeV/c^{2} at low transverse momentum (p_{T}<0.15 GeV/c) in noncentral Au+Au collisions at sqrt[s_{NN}]=200 GeV and U+U collisions at sqrt[s_{NN}]=193 GeV. Significant enhancement factors, expressed as ratios of data over known hadronic contributions, are observed in the 40%-80% centrality of these collisions. The excess yields peak distinctly at low p_{T} with a width (sqrt[⟨p_{T}^{2}⟩]) between 40 and 60 MeV/c. The absolute cross section of the excess depends weakly on centrality, while those from a theoretical model calculation incorporating an in-medium broadened ρ spectral function and radiation from a quark gluon plasma or hadronic cocktail contributions increase dramatically with an increasing number of participant nucleons. Model calculations of photon-photon interactions generated by the initial projectile and target nuclei describe the observed excess yields but fail to reproduce the p_{T}^{2} distributions.

Abstract
MicroRNAs (miRNAs) are small noncoding RNAs approximately with 22 nucleotides. Accumulating evidence indicates that microRNAs are involved in carcinogenesis and tumor progression. Some recent investigations have also reported that several microRNAs could act as biomarkers in cancer diagnosis and prognosis. MicroRNA-589-5p (miR-589-5p) is a less studied microRNA, in this study, we explored its roles in hepatocellular carcinoma (HCC). We analyzed miR-589-5p expression in HCC tissues by sequencing data and proved the expression in liver cancer cell lines by quantitative real-time PCR (qRT-PCR). We studied the effect of miR-589-5p on the growth of liver cancer cells by MTT assay, colony formation and flow cytometry, and identified its target gene by luciferase reporter assay. We found that miR-589-5p was commonly overexpressed in HCC specimens. High expression of miR-589-5p was a risk factor for HCC patient (Hazard ratio [HR] = 1.434; 95% confidence intervals [CI] = 1.006-2.044; p = 0.046). We also found miR-589-5p had higher expression in hepatocarcinoma cell lines HepG2 and HuH-7 than did in normal hepatocyte Lo-2. We identified that suppression of miR-589-5p inhibited cell proliferation and cell cycle progression by loss-of-function studies. Furthermore, we found mitogen-inducible gene 6 (MIG-6) to be a target of miR-589-5p. Our study demonstrated that miR-589-5p facilitated the growth of liver cancer cells by targeting MIG-6 and could be a prognosis biomarker for HCC. Suppression of miR-589-5p may be a feasible approach for inhibiting HCC progress.
