Abstract
Objective: To investigate the breakthrough incidence of invasive fungal disease(IFD) and side effects of posaconazole as primary prophylaxis during induction chemotherapy for acute myeloid leukemia(AML). Methods: A total of 206 newly diagnosed AML patients admitted to our department during January 2016 and December 2018 were enrolled in the study. Exclusive criteria were as followings including patients diagnosed as acute promyelocytic leukemia; those who received intravenous antifungal therapy after admission or had history of IFD one month before induction chemotherapy, or those with functional insufficiency of vital organs and those older than 65. Forty-seven patients received posaconazole (posaconazole group), 61 cases received voriconazole (voriconazole group) and 98 cases did not receive any prophylaxis (control group) during induction chemotherapy. Prophylactic efficacy and safety between posaconazole and voriconazole were compared. Results: During induction chemotherapy, five possible cases of IFD occurred in posaconazole group (10.6%); while 11 cases (18.0%) were in voriconazole group including 7 possible, 3 probable and 1 proven. Thirty-five cases (35.7%) in control group were diagnosed as IFD including 19 possible, 11 probable and 5 proven ones. The incidences of IFD in posaconazole and voriconazole group were significantly lower than that in control group (P<0.05). The difference of posaconazole group and voriconazole group was not significant (P>0.05). The reported adverse events in posaconazole group were significantly lower than those in voriconazole group [12.8%(6/47) vs. 32.8%(20/61), P<0.05]. Conclusions: Posaconazole and voriconazole decrease IFD as primary prophylaxis during induction chemotherapy in patients with AML. The prophylactic effect of IFD with posaconazole is similar as voriconazole, but posaconazole shows better safety.

Abstract
Lung adenocarcinoma (LUAD), a histological subclass of non-small-cell lung cancer, is globally the leading cause of cancer-related deaths. Long noncoding RNAs (lncRNAs) are emerging as cancer regulators. Zinc finger protein multitype 2 antisense RNA 1 (ZFPM2-AS1) is an oncogene in gastric cancer, but its functions have not been investigated in LUAD. We showed that ZFPM2-AS1 expression is high in LUAD samples based on GEPIA database (http://gepia.cancer-pku.cn/) and validated ZFPM2-AS1 upregulation in LUAD cell lines. Functionally, ZFPM2-AS1 facilitated proliferation, invasion, and epithelial-to-mesenchymal transition of LUAD cells. Thereafter, we found that ZFPM2 was negatively regulated by ZFPM2-AS1, and identified the suppressive effect of ZFPM2 regulation by ZFPM2-AS1 on LUAD progression. Mechanistically, we showed that ZFPM2-AS1 interacted with up-frameshift 1 (UPF1) to regulate mRNA decay of ZFPM2. Rescue assays in vitro and in vivo confirmed that ZFPM2-AS1 regulated LUAD progression and tumor growth through ZFPM2. Taken together, our findings demonstrate a role for the ZFPM2-AS1-UPF1-ZFPM2 axis in LUAD progression, suggesting ZFPM2-AS1 as a new potential target for LUAD treatment.

Abstract
PURPOSE Radiotherapy is the main treatment method for patients with locally advanced, unresectable esophageal cancer. The aim of this study is to compare overall survival (OS) using 3D radiotherapy (3DRT) alone with concurrent chemoradiotherapy (CCRT) in 296 non-surgical esophageal carcinoma patients. PATENTS AND METHODS Over 10 years, of the 480 patients with esophageal carcinoma treated with 3DRT with or without chemotherapy, 148 patients each comprised 3DRT and CCRT groups after propensity score matching. RESULTS The 5- and 10-year OS (P=0.337) and PFS (P=0.715) rates for 3DRT alone were 22.0%, 14.4% and 26.1%, 23.2%, respectively, compared with 28.8%, 18.6% and 34.7%, 29.1% for CCRT, respectively. CCRT did not improve 5-year and 10-year OS or PFS in 60-70Gy group (OS: 27.5% and 25.2%; 17.9% and 17.0%, P=0.938; PFS: 38.3% and 31.8%; 31.9% and 27.8%, P=0.890) nor reduce 10-year hematogenous metastasis (31.7% and 28.3%, P=0.698). CCRT improved 5-year OS and PFS of 50.0-59.9Gy group (OS: 33.3% and 12.0%, P=0.029; PFS: 33.1% and 10.6%, P=0.081). For 3DRT, the 5-year OS and PFS rates were significantly better in the 60-70Gy group (P=0.017) compared with 50.0-59.9Gy group (P=0.002). For CCRT group, 5-year OS and PFS favored the 50.0-59.9Gy group, but the difference was insignificant. Major toxicities were greater with CCRT compared with 3DRT. CONCLUSION For non-surgical esophageal carcinoma patients, 3DRT combined with CCRT was effective in prolonging both OS and PFS.

Abstract
Clinical Case
An 89-year old lady presented with symptoms of chest pain and dyspnea, without a significant cardiovascular history, regular medical therapy nor any cardiac risk factors.
The electrocardiogram (ECG) demonstrated hyper-acute T waves, and moderate troponin T elevation which peaked at 998 ng/ml. Transthoracic echocardiography (TTE) demonstrated apical ballooning, with hyperdynamic function of the basal left ventricle (LV). These findings were suggestive of a diagnosis of Takotsubo’s cardiomyopathy (TTC), further supported by the coronary angiogram, which confirmed the absence of obstructive coronary artery disease. Notably, her symptoms had not occurred in the setting of emotional or physical stress.
The initial recovery was uncomplicated, with no recurrence of symptoms, arrhythmias or cardiac failure. Five days after her presentation, she suddenly experienced severe chest pain and dyspnea associated with profound hypotension. The ECG demonstrated widespread, deep T wave inversion which had evolved over the preceding days, without new ischaemic ST segment changes. Bedside TTE demonstrated severe eccentric mitral regurgitation (MR) with an anteriorly directed jet, not present on earlier TTE, and a hyperdynamic LV. Stability was re-established with intravenous vasopressors, and subsequently with an intra-aortic balloon pump. Transoesophageal echocardiography to evaluate the aetiology of the acute MR demonstrated rupture of the antero-medial papillary muscle with a resultant flail posterior mitral valve leaflet.
She was managed with a palliative, non-surgical approach following consideration of her advanced age, frailty, and wishes, and passed away the following day.
Discussion
TTC is characterized by transient LV impairment, typically due to apical ballooning, with a modest troponin elevation and ECG changes that can mimic acute myocardial infarction. There is, however, an absence of obstructive coronary artery disease. It is most common in post-menopausal females. The overall prognosis is favourable, but can be complicated by cardiac failure, ventricular arrhythmias, and thrombo-embolic phenomena, which carry a significant in-hospital mortality.
Rarely, acute MR due to systolic anterior motion of the mitral valve with LV outflow tract obstruction can complicate TTC. Acute MR due to papillary muscle rupture, as in this case, is unusual and has only been reported on a few occasions. The mechanism is not well understood as this pathology is usually found in the context of myocardial infarction, which is excluded on coronary angiography as part of the diagnostic evaluation TTC. Two potential mechanisms have been proposed. As is the case in dilated cardiomyopathy, dilatation of the LV in TTC may create abnormal tension on the tendinae chordae and papillary muscle, or microvascular ischaemia, which has been postulated as a cause for TTC, either of which may then lead to spontaneous papillary muscle rupture.

Abstract
OBJECTIVE To investigate the levels of period circadian protein homolog 3 (PER3) in paclitaxel-resistant prostate cancer patients and the effect of PER3 on paclitaxel-resistant prostate cancer cell lines. PATIENTS AND METHODS A total of 38 patients diagnosed with prostate cancer in our hospital from June 2013 to June 2016 were divided into paclitaxel-resistant group (n=19) and non-resistant group (n=19) according to the follow-up treatment effects. Fluorescent quantitative polymerase chain reaction (PCR) was performed to evaluate the levels of PER3 in drug-resistant and non-resistant groups as well as the relative levels of PER3 before and after treatment. PER3 was overexpressed or knocked down in a paclitaxel-resistant prostate cancer cell line, followed by measuring its IC50 as well as changes in cell cycle and apoptosis. Using Western blot, we detected downregulation of Notch pathway and related receptor proteins when PER3 was overexpressed. RESULTS The results of fluorescence quantitative PCR showed that the expression of PER3 in the paclitaxel-resistant prostate cancer group was lower than that in the non-resistant group, and the relative expression of PER3 was decreased after treatment. Fluorescent quantitative PCR and Western blot showed that the expression of PER3 in paclitaxel-resistant prostate cancer cells was higher than that of the untreated counterparts. After overexpression of PER3 by transfecting prostate cancer-resistant cell lines with plasmids, the IC50 was significantly reduced, the cell cycle was arrested, and the apoptosis was significantly increased. Subsequently, we detected decreased expression of Notch1 in PER3 over-expressed paclitaxel-resistant cell lines by Western blot; this attenuated resistance in paclitaxel-resistant cell lines. CONCLUSIONS PER3 can induce sensitivity of paclitaxel-resistant cell lines to paclitaxel by inhibiting the expression of Notch1.

Abstract
Objective: To analyze the relationship between the severity of esophageal acid reflux and esophageal motility, esophageal mucosal injury and morphological anatomy of gastroesophageal junction (GEJ) in patients with gastroesophageal reflux disease (GERD). Methods: The clinicaldata of GERD patients who underwent 24 h pH-impedance monitoring, gastroscopy and high-resolution manometry (HRM) from January 2016 to January 2019 in the Gastroesophageal Surgery Department of PLA Rocket Force Characteristic Medical Center were retrospectively analyzed. The patients were divided into non-pathological acid reflux group, mild pathological acid reflux group and moderate to severe pathological acid reflux group according to the DeMeester score. The gender and age of each group were matched, with 60 cases in each group. Statistical analysiswas performed to analyze thedifferences in upper esophageal sphincter pressure, lower esophageal sphincter pressure (LES), LES length, length of ventral LES, percentage of ineffective swallowing, esophagitis, Hill grade of GEJ, and hiatus hernia (HH) in each group. The comparison and correlation analysis are also carried out between the groups. Results: The male-female ratio was 33/27, and the age was (57±13) years in each group. Non-parametric analysis showed that the LES pressure and the length of the ventral LES decreased with the severity of acid reflux, and there was a statistical difference (P= 0.033, P=0.015). The detection rate of HH by HRM increased significantly (χ(2)=0.001) as well. Esophagitis score increased with the severity of acid reflux and there was statistical difference (P<0.001).The detection rate of esophagitis increased significantly (χ(2)<0.001) as well. Hill grading score of GEJ increased with the severity of acid reflux, and there was statistical difference (P<0.001).The detection rate of HH by endoscopy increased significantly (χ(2)<0.001) as well. The correlation between DeMeester score and LES pressure, length of ventral LES, percentage of ineffective swallowing, esophagitis score, and Hill grade score were statistically significant (P<0.05). Conclusions: The esophageal low motility (such as low LES pressure) and anatomical abnormalities (abdominal esophageal shortening, GEJ flabbiness, and even HH formation) of the GEJ regionare significantly associated with the severity of acid reflux. These factors may be important causes of increased acid reflux. In addition, the aggravation of acid reflux can also increase the incidence and severity of esophagitis.

Abstract
Target leaf spot (TLS) of sorghum, a foliar disease caused by the necrotrophic fungus Bipolaris cookei (also known as Bipolaris sorghicola), can affect grain yield in sorghum by causing premature drying of leaves and defoliation. Two sorghum recombinant inbred line (RIL) populations, BTx623/BTx642 and BTx623/SC155-14E, were assessed for TLS resistance in replicated trials. Using least square mean trait data, four TLS resistance QTL were identified, two in each population. Of these, three were previously unidentified while a major QTL on chromosome 5 in the BTx623/BTx642 RIL population corresponded to the previously identified TLS resistance gene ds1. A set of sorghum lines were assessed for production of reactive oxygen species induced by treatment with the microbe-associated molecular pattern (MAMP) flg22 (a derivative of flagellin). Flg22-induced ROS production varied between lines in a consistent fashion. One QTL associated with variation in the flg22 response was detected in the RIL populations. No evidence was found to link variation in the MAMP response to variation in TLS resistance.

Abstract
This study was carried out to investigate the effects of pH and heat on the structure and function of milk proteins by comparing goat milk treated under different pH and temperature conditions. The results showed that pH had a significant effect on the thermal stability of goat milk proteins, and the proteins were least thermally stable at pH 7.7. Except for the pH 6.9 goat milk, the surface hydrophobicities of the milk proteins at various pH values reached their maxima at 85°C. The particle size, zeta potential, and content of regular secondary structure also decreased significantly at 85°C, and the turbidity of milk proteins under alkaline pH conditions was lower than that under acidic conditions. It was concluded that alkaline conditions resulted in better emulsion stability and oil-holding capacity, and acidic conditions offered better foaming ability, foam stability, and water-holding capacity for goat milk protein during heat processing. It can also be seen that 85°C was the key temperature for milk proteins after changing the pH of the milk. This paper provides a theoretical basis for optimizing the processing conditions for goat milk and the applications of goat milk proteins.

Abstract
OBJECTIVE Previous investigations have shown that miR-183 is upregulated in bladder cancer (BC); however, its biological significance is not fully investigated. The goal of the current study is to analyze the function of miR-183 in BC development and progression. PATIENTS AND METHODS 23 pairs of BC tumor and adjacent tissues were analyzed for miR-183 and c-Myc expression using Real-time polymerase chain reaction (PCR). MiR-183 expression was modulated by transfection of miR-183 or miR-183 inhibitor (miR-183-in). Protein expression of AXIN2, c-Myc and Cyclin D1 was determined by western blot. Cell growth activity and apoptotic potential were evaluated by cell viability assay and flow cytometry assay, respectively. Luciferase activity assay was conducted to determine whether AXIN2 is a direct target of miR-183. RESULTS The expression of miR-183 is upregulated in BC tissues and cell lines, and is positively correlated with the expression of the Wnt target gene, c-Myc. MiR-183 positively regulated Wnt signaling activity by directly suppressing its negative feedback regulator, AXIN2. Overexpression of miR-183 promoted cell growth and inhibited apoptosis. Inhibition of miR-183 attenuated cell growth and enhanced apoptosis. The effect of miR-183 on cell growth and apoptosis can be abolished by knockdown of AXIN2. CONCLUSIONS MiR-183 functions as an oncomiR in BC and upregulates Wnt signaling activity by directly suppressing AXIN2 expression.

Abstract
LncRNA PITPNA-AS1 was a newly identified lncRNA which has never been studied in cancers. Whether PITPNA-AS1 participated in the development of hepatocellular carcinoma (HCC) is obscure. Given the coaction of lncRNAs and miRNAs to carcinogenesis, the purpose of the present research is to inquire how PITPNA-AS1 affects HCC progression. Firstly, PITPNA-AS1 was observed to be heightened in HCC tissues. Then function assays proved that overexpressing or silencing PITPNA-AS1 could manipulate the proliferation and motility of HCC cells. Besides, PITPNA-AS1 was located in the cytoplasm. Among the candidate miRNAs of PITPNA-AS1, miR-876-5p was an obvious target. Moreover, mechanism experiments validated that PITPNA-AS1 modulated WNT5A expression by targeting miR-876-5p. Rescue experiments affirmed that WNT5A silencing rescued the miR-876-5p suppression-induced cellular processes in PITPNA-AS1-silenced Hep3B cells. And in vivo experiments determined that PITPNA-AS1 regulated HCC progression in vivo via miR-876-5p/WNT5A pathway. In conclusion, this work shed lights on the modulatory mechanism of PITPNA-AS1/miR-876-5p/WNT5A axis in HCC, which might be pivotal for exploring effective diagnostic biomarkers and treatment strategies for HCC patients.

Abstract
Andrias davidianus is widely recognized in traditional medicine as a cure-all to treat a plethora of ailments. In a previous study, a novel antibacterial peptide named andricin B was isolated from A. davidianus blood. In this study, we investigated andricin B structure and its mode of action. Circular dichroism spectra suggested that andricin B adopts a random coil state in aqueous solution and a more rigid conformation in the presence of bacteria. Moreover propidium iodide/fluorescein diacetate double staining indicated that bacteria treated with andricin B were not immediately eliminated. Rather, there is a gradual bacterial death, followed by a sublethal stage. Scanning electronic microscope imaging indicates that andricin B might form pores on cell membranes, leading to the release of cytoplasmic contents. These results were consistent with flow cytometry analysis. Furthermore, Fourier transform infrared spectroscopy suggests that andricin B induces changes in the chemical properties in the areas surrounding these "pores" on the cell membranes. SIGNIFICANCE AND IMPACT OF THE STUDY: The results of this study suggested the new perspectives about the mode of action of antimicrobial peptide (AMP) active against sensitive bacteria. The AMP was able to be in a random coiled state in aqueous solution but to change to a more rigid one in the presence of sensitive bacteria. Exposure to AMP might not lead to immediate death of treated bacteria, rather bacteria concentration decreased gradually flattening at a sublethal stage. These findings will help people to understand better how the AMPs activate against sensitive bacteria.

Abstract
OBJECTIVES To investigate the fetal adverse pregnancy outcomes (APOs) and the predictive value of umbilical arterial Doppler ultrasonography in the third trimester in pregnant women with lupus nephritis (LN). METHODS A retrospective cohort study enrolling 203 LN patients from 2007 to 2017 was performed. Ultrasonic parameters were recorded. RESULTS Fetal APOs occurred in 103 patients (103/203, 50.7%). Sixty-six pregnancies (66/203, 32.5%) ended with preterm births. The incidence rate of intrauterine growth restriction (IUGR) was 18.2% (37/203). Fetal distress was noted in 23 pregnancies (23/203, 11.3%). All the Doppler parameters elevated in patients with IUGR, fetal distress, and composite conditions. Resistance index (RI) indicated the highest risk of IUGR and composite APOs. The cutoff values were 0.66 and 0.67, respectively. Sensitivities were 51.4% and 33.7%, and specificities were 87.4% and 92.1%. Peak velocity of the umbilical arteries at end-systole (Vmax, abbreviated as S) to that at end-diastole (Vmin, abbreviated as D) (S/D) ratio was also a best predictor for IUGR, with the optimal cutoff value of 2.88. Sensitivity and specificity were comparable with RI. Pulsatility index (PI) over 0.84 was an ideal indicator for fetal distress with an optimal combination of sensitivity (89.5%) and specificity (51.6%). CONCLUSIONS Fetal complications were frequent in patients with LN. Umbilical arterial Doppler ultrasonography was a useful measure to predict late IUGR, fetal distress, and the composite APOs.

Abstract
Abstract
Objective
While the use of validity testing in neuropsychological assessments to assist in differentiation between epileptic seizures (ES) and psychogenic non-epileptic events (PNEE) is becoming common, validity considerations regarding symptom self-reporting is seldom examined. This study seeks to add clarity by examining performance validity tests (PVT), and self-report measures of emotional symptoms and daily functioning, in a sample of those with either ES or PNEE.
Methods
Patients: Consecutive Veteran patients referred to an epilepsy monitoring unit for evaluation of intractable seizures, and subsequently diagnosed with ES (32) or PNEE (75). A fixed battery of psychological (Beck Depression Inventory-II, Patient Competency Rating Scale, Quality of Life in Epilepsy) and PVT (Test of Memory Malinger, Word Memory Test) measures were administered as part of a broader neuropsychological assessment. Patients were classified by both their diagnostic, and PVT pass/fail, statuses (PNEEpass, PNEEfail, & ESpass – ESfail was too small to analyze).
Results
PNEE reported more severe symptoms/impairments than ES (each p < .01) when ignoring PVT results. Importantly, when PVTs were considered, PNEEfail reported worse symptoms/impairments than PNEEpass (each p < .01), and PNEEpass and ESpass did not differ on emotional distress (p = .07).
Conclusions
Those with PNEE who fail PVTs report worse psychological distress and functional abilities than both those who pass and those with ES. This is likely due to symptom exaggeration. Validity testing should thus be considered a crucial component of assessment of these individuals: if invalid self-reporting is not accounted for, clinicians put themselves at risk for coming to faulty conclusions while more parsimonious explanations are available.

Abstract
We report on the highest energy photons from the Crab Nebula observed by the Tibet air shower array with the underground water-Cherenkov-type muon detector array. Based on the criterion of a muon number measured in an air shower, we successfully suppress 99.92% of the cosmic-ray background events with energies E>100 TeV. As a result, we observed 24 photonlike events with E>100 TeV against 5.5 background events, which corresponds to a 5.6σ statistical significance. This is the first detection of photons with E>100 TeV from an astrophysical source.

Abstract
Objective: To investigate the clinical effect of the flap on post aurem and mastoid region on immediate repair of part helix defect. Method: Fifteen patients with part helix defect were immediately repaired using the flap on post aurem and mastoid region. Firstly, the skin tissue above the defect of the helix was used as the pedicle. The flap was drawn toward the post aurem and mastoid region closing to the auriculocephalic angle. The flap was generally 3-4 cm long and at least 1 cm wide. Secondly, the flap was lifted on the perichondrium, and the structure of the helix was formed by upward rotation of the flap to repair the defect of the helix. Finally, the flap was sutured to repair the helix defect. Result: Fifteen cases were applied with this method to repair immediately the defect in the emergency environment. The sizes of helix contour were satisfactory and the auriculocephalic angles had not changed. The ear shape was stable after 1 to 3 months of followup. Conclusion: The flap on post aurem and mastoid region could immediately repair the part helix defect. It has the advantages of simple operation, high flap survival rate and one-time satisfactory shape..

Abstract
Hereditary gingival fibromatosis (HGF) is a highly genetically heterogeneous disease, and current therapeutic method is limited to surgical resection with a high recurrence rate. MicroRNAs (miRNAs) are able to fine-tune large-scale target genes. Here we established a simple but effective computational strategy based on available miRNA target prediction algorithms to pinpoint the most potent miRNA that could negatively regulate a group of functional genes. Based on this rationale, miR-335-3p was top ranked by putatively targeting 85 verified profibrotic genes and 79 upregulated genes in HGF patients. Experimentally, downregulation of miR-355-3p was demonstrated in HGF-derived gingival fibroblasts as well as in transforming growth factor β–stimulated normal human gingival fibroblasts (NHGFs) compared to normal control. Ectopic miR-335-3p attenuated, whereas knockdown of miR-335-3p promoted, the fibrogenic activity of human gingival fibroblasts. Mechanically, miR-335-3p directly targeted SOS1, SMAD2/3, and CTNNB1 by canonical and noncanonical base paring. In particular, different portfolios of fibrotic markers were suppressed by silencing SOS1, SMAD2/3, or CTNNB1, respectively. Thus, our study first proposes a novel miRNA screening approach targeting a functionally related gene set and identifies miR-335-3p as a novel target for HGF treatment. Mechanically, miR-335-3p suppresses the fibrogenic activity of human gingival fibroblasts by repressing multiple core molecules in profibrotic networks. Our strategy provides a new paradigm in the treatment for HGF as well as other diseases.

Abstract
Background:
Experimental animal model studies have shown neuroprotective properties of magnesium. We assessed the relationship between admission magnesium and admission stroke severity and 3-month clinical outcomes in patients with acute intracerebral hemorrhage (ICH).
Methods:
The present study included 323 patients with acute ICH who were prospectively identified. Demographic characteristics, lifestyle risk factors, National Institute of Health Stroke Scale (NIHSS) score, hematoma volumes, and other clinical features were recorded at baseline for all participants. Patients were divided into three groups based on the admission magnesium levels (T1: <0.84; T2: 0.84-0.91; T3: =0.91 mmol/L). Clinical outcomes were death, poor functional outcome (defined by modified rankin ccale [mRS] scores 3-6) at 3 months.
Results:
After 3-month follow-up, 40 (12.4%) all-cause mortality and 132 (40.9%) poor functional outcome were documented. Median NIHSS scores for each tertile (T1 to T3) were 8.0, 5.5, and 6.0, and median hematoma volumes were 10.0, 8.05, and 12.4 ml, respectively. There was no significant association between baseline NIHSS scores (P=0.176) and hematoma volumes (P=0.442) in T3 and T1 in multivariable linear regression models. Compared with the patients in T1, those in T3 were associated with less frequency of all-cause mortality [adjusted odds ratio (OR), 0.10; 95% confidence interval (CI), 0.02-0.54; P-trend=0.010] but not poor functional outcome (adjusted OR, 1.80; 95%CI, 0.71-4.56; P-trend=0.227) after adjustment for potential confounders.
Conclusion:
Elevated admission serum magnesium level is associated with lower odds of mortality but not poor functional outcome at 3 months in patients with acute ICH.

Abstract
BACKGROUND The associations between red and processed meat consumption and esophageal cancer risk remain inconclusive. We performed a systematic review and meta-analysis to analyze these associations. METHODS We searched PubMed and EMBASE to identify studies published between the databases' dates of inception and May 2019. RESULTS We ultimately selected 33 eligible studies for analysis. We found that the summary relative risks for the associations between meat consumption and esophageal cancer risk were positive for the case-control studies (P < 0.05), but negative for the cohort studies included in the analysis (P > 0.05). Subtype analysis indicated that red and processed meat consumption was not associated with the risks of esophageal adenocarcinoma (P > 0.05) and esophageal squamous cell carcinoma (P > 0.05) in the cohort studies. CONCLUSIONS We found case-control but not cohort studies to associate consumption of red and processed meat with the risk of esophageal cancer. Further large prospective studies are needed to validate these findings.

Abstract
Abstract In 2014, the International Endohernia Society (IEHS) published the first international “Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias.” Guidelines reflect the currently best available evidence in diagnostics and therapy and give recommendations to help surgeons to standardize their techniques and to improve their results. However, science is a dynamic field which is continuously developing. Therefore, guidelines require regular updates to keep pace with the evolving literature. Methods For the development of the original guidelines, all relevant literature published up to year 2012 was analyzed using the ranking of the Oxford Centre for Evidence-Based Medicine. For the present update, all of the previous authors were asked to evaluate the literature published during the recent years from 2012 to 2017 and revise their statements and recommendations given in the initial guidelines accordingly. In two Consensus Conferences (October 2017 Beijing, March 2018 Cologne), the updates were presented, discussed, and confirmed. To avoid redundancy, only new statements or recommendations are included in this paper. Therefore, for full understanding both of the guidelines, the original and the current, must be read. In addition, the new developments in repair of abdominal wall hernias like surgical techniques within the abdominal wall, release operations (transversus muscle release, component separation), Botox application, and robot-assisted repair methods were included. Results Due to an increase of the number of patients and further development of surgical techniques, repair of primary and secondary abdominal wall hernias attracts increasing interests of many surgeons. Whereas up to three decades ago hernia-related publications did not exceed 20 per year, currently this number is about 10-fold higher. Recent years are characterized by the advent of new techniques—minimal invasive techniques using robotics and laparoscopy, totally extraperitoneal repairs, novel myofascial release techniques for optimal closure of large defects, and Botox for relaxing the abdominal wall. Furthermore, a concomitant rectus diastasis was recognized as a significant risk factor for recurrence. Despite insufficient evidence with respect to these new techniques, it seemed to us necessary to include them in the update to stimulate surgeons to do research in these fields. Conclusion Guidelines are recommendations based on best available evidence intended to help the surgeon to improve the quality of his daily work. However, science is a continuously evolving process, and as such guidelines should be updated about every 3 years. For a comprehensive reference, however, it is suggested to read both the initial guidelines published in 2014 together with the update. Moreover, the presented update includes also techniques which were not known 3 years before.

Abstract
Hypofractionated stereotactic radiotherapy (HFSRT) is a common salvage treatment for recurrent malignant glioma (MG). However, it remains controversial whether the combination of HFSRT and chemotherapy could improve survival for patients with recurrent MG compared to HFSRT alone. The present systematic review and meta-analysis aims to investigate this question, and tries to determine to what extent the addition of chemotherapy to HFSRT affects survival. A systematic review was performed to analyse the survival for patients treated with HFSRT combined with chemotherapy or not. Hazard ratios (HRs) with 95% confidence intervals (CIs) for overall survival (OS) were pooled with random effects; and standard mean difference (MD) with 95% CIs for OS were pooled using the same strategy. A total of 7 studies including 388 patients with recurrent MG were eligible for our study. The OS survival of patients receiving combination therapy ranged from 8.7 to 23 months, and the median OS of patients underwent HFSRT ranged from 3.9 to 12 months. The meta-analyses resulted in the pooled HR of 0.44 (95% CI 0.30-0.65, p < 0.0001) (Cochran Q statistic 4.70, P = 0.320, I2 = 14.8%) and pooled standard MD of 0.80 months (95% CI 0.41-1.18, p < 0.001) (Cochran Q statistic 10.16, p = 0.71, I2 = 50.8%). The present study suggests that HFSRT + chemotherapy confers a slight survival improvement for patients with recurrent MG as compared with sole HFSRT management. To draw a more solid conclusion, greater investigation is warranted.

Abstract
Background Chemoresistance is a major obstacle for the effective treatment of lung adenocarcinoma (LAD). Forkhead box (FOX) proteins have been demonstrated to play critical roles in promoting epithelial-mesenchymal transition (EMT) and chemoresistance. However, whether FOX proteins contribute to the acquisition of EMT and chemoresistance in LAD remains largely unknown. Methods FOX-A1 expression was measured in LAD cells and tissues by qRT-PCR. The expression levels of EMT markers were detected by western blotting and immunofluorescence assay. The interaction between Sex determining region Y-box protein 5 (SOX5) and FOX-A1 was validated by chromatin immunoprecipitation sequence (ChIP-seq) and Chromatin immunoprecipitation (ChIP) assay. Kaplan-Meier analysis and multivariate Cox regression analysis were performed to analyze the significance of FOX-A1 and SOX5 expression in the prognosis of LAD patients. Findings FOX-A1 was upregulated in docetaxel-resistant LAD cells. High FOX-A1 expression was closely associated with a worse prognosis. Upregulation of FOX-A1 in LAD samples indicated short progression-free survival (PFS) and overall survival (OS). SOX5 is a new and direct target of FOX-A1 and was positively regulated by FOX-A1 in LAD cell lines. Knockdown of FOX-A1 or SOX5 reversed the chemoresistance of docetaxel-resistant LAD cells by suppressing cell proliferation, migration and EMT progress. Interpretation These data elucidated an original FOX-A1/SOX5 pathway that represents a promising therapeutic target for chemosensitizing LAD and provides predictive biomarkers for evaluating the efficacy of chemotherapies.

Abstract
We have upgraded the new Tibet ASgamma experiment in China since 2014 to measure the chemical composition of cosmic rays around the knee. This hybrid experiment consist of an air-shower-core detector array (YAC-II) to detect high energy electromagnetic component, the Tibet air-shower array (Tibet-III) and a large underground water-Cherenkov muon-detector array (MD). We have carried out a detailed air-shower Monte Carlo (MC) simulation to study the performance of the hybrid detectors by using CORSIKA (version 7.5000), which includes EPOS-LHC, QGSJETII-04, SIBYLL2.1 and SIBYLL2.3 hadronic interaction models. The preliminary results of the interaction model checking above 50 TeV energy region are reported in this paper, and the primary proton and helium spectra in the energy range 50 TeV to 1015 eV was derived from YAC-I data and is smoothly connected with direct observation data at lower energies and also with our previously reported works at higher energies within statistical errors. The knee of the (P+He) spectra is located around 400 TeV. The interaction model dependence in deriving the primary (P+He) spectra is found to be small (less than 25% in absolute intensity, 10% in position of the knee), and the composition model dependence is less than 10% in absolute intensity.

Abstract
Fever and abdominal pain are common symptoms and could be main manifestations in patients with autoinflammatory diseases. A 48-year-old female patient was admitted with recurrent fever and abdominal pain for 9 years. Serum level of inflammatory markers synchronously fluctuated with fever, and returned to normal when fever subsided. The periodic episodes of fever occurred every 1 to 4 months and failed to respond to empirical antibiotics. Whole exome sequencing showed heterozygous mutation of NOD2 gene q902k, leading to the final diagnosis of autoinflammatory disease. Corticosteroid and tripterygiumglycosides were effective for the disease remission.

Abstract
Intestinal mucositis is a frequent side effect in cancer patients who are treated with chemotherapy. There are no effective treatment strategies to date. To find a novel way to alleviate mucositis, the effects of selenium-enriched Bifidobacterium longum (Se-B. longum) in preventing irinotecan (CPT-11)-induced intestinal mucositis in a mouse model were investigated. We tested the ability of Se-B. longum (Se 0.6 mg/kg, 5×108 cfu/mice) to reduce small intestinal mucositis induced by CPT-11 (75 mg/kg, daily) injected intraperitoneally for four consecutive days in mice. Se-B. longum significantly decreased mortality induced by CPT-11 from 71.4% to 16.7%. CPT-11 induced body weight loss, which was alleviated by preventative and simultaneous administration of Se-B. longum. Se-B. longum significantly decreased the severity of diarrhoea from 11 to 4% compared to the CPT-11 group. Inflammation, including intestinal shortening and upregulation of tumour necrosis factor-α and interleukin-1β induced by CPT- 11, were prevented by Se-B. longum. Se-B. longum is effective in preventing small intestinal mucositis induced by CPT-11 and therefore has potential to be used clinically by cancer patients.
