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
Carbon-based, all-inorganic perovskite solar cells (PSCs) have drawn enormous attention recently on account of their ungraded stability and reduced costs. However, their power conversion efficiencies (PCEs) still lag behind the ones with conventional architecture. Moreover, the high cost of FTO substrates and energy-consuming sintering process of TiO2 electron-transporting layers should be further addressed. Herein, it is demonstrated that the FTO/TiO2 substrates could be separated simply from degraded CsPbIBr2 PSCs for fabricating the new ones again, which thus reduces the production costs of resulting PSCs and makes them renewable and sustainable. Meanwhile, the characterization results reveal that there are some residual CsPbIBr2-derived species on recycled FTO/TiO2 substrates, which enable the upper CsPbIBr2 films with suppressed halide phase separation and reduced defects, the diminished work function of TiO2 layers from 4.13 to 3.89 eV, along with decreased conduction band minimum (CBM) difference of CsPbIBr2/TiO2 interface from 0.51 to 0.36 eV. Consequently, the average PCE of CsPbIBr2 PSCs is improved by 20%, from 6.51 ± 0.62% to 8.14 ± 0.63%, wherein the champion one yields the exceptional value of 9.12%. These findings provide an avenue for simultaneous performance enhancement and cost-saving of carbon-based, all-inorganic PSCs to promote their commercialization.

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
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
A high-performance transfer printing method using a new soluble tape which can be dissolved in acetone is proposed to be used in heterogeneous integration. Si inks array was transferred from SOI wafers onto various substrates without adhesion promoter by this new method which we refer to as the acetone soluble tape (AST) method to compare with other transfer printing methods by using thermal release tape (TRT), water soluble tape (WST) and polydimethylsiloxane (PDMS). By using the AST method, the transfer printing process does not involve interface contention between stamp/inks and inks/receiver substrate so that it maximizes the transfer printing efficiency. Experimental results present the AST method has good performances, and various alien substrates, even curvilinear surfaces, can be selected as receiver substrates by the AST method. To examine the quality of the transferred Si inks, the Si TFTs were fabricated by using the Si membrane transferred by the AST method on sapphire substrate and the devices show the good performance. All the results confirm that the AST method is an effective method in heterogeneous integration.

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 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
Inorganic halide perovskite CsPbBr3 is emerging as one of the promising alternatives to the hybrid counterparts for optoelectronic applications owing to its upgraded stability. Yet, the inherently low solubility of a CsBr precursor material restricts the quality and especially the thickness of a solution-processed CsPbBr3 film, thus hindering the further optimization of device performance. Herein, we report a facile intermediate phase halide exchange reaction that can break the thickness limit of a solution-processed CsPbBr3 film, since it avoids the use of low-solubility CsBr. Furthermore, the CH3NH3I byproduct after halide exchange could trigger a beneficial Ostwald ripening process to promote grain coarsening in the film. Hence, the uniformly flat, pure-phase, and compact CsPbBr3 film composed of [100] preferential, microsized grains can be achieved. As a demonstration of its excellent optoelectronic features, the carbon-based, all-inorganic photodetector with such a favorable film yields a maximum photoresponsivity of 0.35 A W-1 and a specific detectivity of 1.94 × 1013 Jones coupled with a response time of 0.58 μs.

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
Perovskite CsPbIBr2 is attracting ever-increasing attention for carbon-based, all-inorganic solar cells, owing to its well-balanced band gap and stability features. However, significant interfacial recombination of charge carriers in solar cells fabricated with this active layer, which is intrinsically associated with the unwanted conduction band misalignment between CsPbIBr2 and the commonly used TiO2 electron transport layer, has limited power conversion efficiency (PCE) values. Herein, we demonstrate successful conduction band alignment engineering at the TiO2 /CsPbIBr2 heterojunction by modifying TiO2 with CsBr clusters. Such modification triggers a beneficial increase in the conduction band minimum (CBM) of TiO2 from -4.00 to -3.81 eV and decreases the work function from 4.11 to 3.86 eV, thus promoting favorable band alignment at the heterojunction, suppressing recombination, and improving extraction and transport of charge carriers. As a result, the carbon-based, all-inorganic CsPbIBr2 solar cells exhibit over 20 % enhancement in average PCE. The champion device achieves a PCE of 10.71 %, a record among pure CsPbIBr2 -based cells, open-circuit voltage of 1.261 V, and excellent stability.

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.

Abstract
Objective: To analyze the prognostic impact of Ikaros family zinc finger 1(IKZF1) mutation on adult Philadelphia chromosome (Ph1) positive acute lymphoblastic leukemia (ALL) patients. Methods: IKZF1 mutation was detected in 63 adult Ph1 positive ALL patients at diagnosis using capillary electrophoresis. Recruited patients were treated in our center and other three hospitals in Ningbo from January 2014 to January 2017. Clinical data were collected and retrospectively analyzed. Results: Thirty-nine (61.9%) patients were positive IKZF1 mutation in this cohort. The white blood cell (WBC) count in IKZF1 mutation group was significantly higher than that of mutation negative group [(64.6±11.3)×10(9)/L vs. (33.7±5.6)×10(9)/L, P<0.05]. Patients with WBC count over 30×10(9)/L accounted for 56.4% in IKZF1 mutation group. Complete remission (CR) rate in the IKZF1 mutation group was also lower than that of negative group after induction chemotherapy (64.1% vs. 75.0%, P>0.05). IKZF1 was a negative prognostic factor but not independent factor for survival by univariate and multivariate analyses. Patients were divided into chemotherapy and allogeneic transplantation groups. The 3-year overall survival (OS) rate and 3-year leukemia-free survival (LFS) rate in IKZF1 mutation group were significantly lower than those of negative group in both transplantation group (42.3% vs. 59.3%; 31.2% vs. 50.0%; respectively, both P<0.05) and chemotherapy group (24.8% vs. 40.0%; 19.0% vs. 34.3%; respectively, both P<0.05). Conclusion: IKZF1 mutation is a poor prognostic factor for adult Ph1 positive ALL patients.
