Abstract
High-grain non-pelleted (HG) and high-grain pelleted (HP) diets are becoming prevalent for ruminant feeding in intensive farms. However, rare information is about their effect on sheep and the comparison between these two kinds of diets. The current study investigated how HG and HP diets affected the transcriptome profiles of rumen epithelium in Hu-lamb. Fifteen male Hu-lambs were assigned randomly to three groups (n = 5 for each group). Lambs in the control (CON), HG, and HP groups were fed with low-grain non-pelleted diet (30% grain), HG diet (70% grain), and HP diet (70% grain), respectively, for 42 days. All these lambs were slaughtered to collect ruminal epithelium samples for transcriptome analysis. Results showed both HG and HP diets obviously changed the transcriptome profiles, and 192, 319, and three differentially expressed genes (DEGs) were identified for CON_HG, CON_HP, and HG_HP comparisons, respectively. Clusters of orthologous group functional classification of CON_HG and CON_HP DEG datasets both showed the enrichments of DEGs in pathways involved in protein biogenesis and modification as well as energy production and conversion. Kyoto encyclopedia of genes and genomes pathway analysis of CON_HG and CON_HP DEG datasets both displayed the enrichments of DEGs in ribosome and oxidative phosphorylation. Almost all these DEGs involved in translation and ribosomal structure and biogenesis as well as oxidative phosphorylation were downregulated in the HG and HP groups compared to the CON group. Furthermore, CON_HP comparison demonstrated more DEGs related to these two pathways than CON_HG comparison. In conclusion, both HG and HP diets inhibited energy production and conversion as well as protein synthesis and modification in ruminal epithelium. HP diet showed lower growth benefits, induced severer rumen acidosis, and more seriously inhibited energy production and protein synthesis as compared to HG diet.

Abstract
BACKGROUND Aortic stenosis (AS) is no longer considered to be a disease of fixed left ventricular (LV) afterload, but rather, functions as a series circuit, with important contributions from both the valve and vasculature. Patients with AS are typically elderly, with hypertension and a markedly remodelled aorta. The arterial component is sizeable, and yet, quantifying this to-date has been difficult to determine. We compared measurement of aortic pressure, flow and global LV load using a cardiac magnetic resonance (CMR)/applanation tonometry (AT) technique to uncouple ventriculo-arterial (VA) interactions. METHODS 20 healthy elderly patients and 20 with AS underwent a CMR/AT protocol. CMR provided LV volume and aortic flow simultaneously with AT pressure acquisition. Aortic pressure was derived by transformation of the AT waveform. Systemic vascular resistance (SVR) and global LV load were determined as the relationship of pressure to flow in the frequency domain. Values from both cohorts were compared. RESULTS AS patients were older (p < 0.01) albeit with no significant difference in brachial or central aortic pressure. SVR (14228 vs 19906 dyne s.cm-3; p = 0.02) and load (740 vs 946 dyne s.cm-3; p = 0.02) were higher in patients with AS, whilst aortic peak flow velocity was lower (38 vs 58 cm/s; p < 0.01). CONCLUSIONS Quantification of aortic pressure, flow velocity and global LV load using a simultaneous CMR/AT technique is able to demonstrate the progressive effects of hypertension and aortic stiffening with advanced age and valvular stenosis. This technique may help to better identify future patients at risk of VA coupling mismatch after correction of AS.

Abstract
PURPOSE To evaluate the potential feasibility of Al[18F]F-1,4,7-triazacyclononane-1,4,7-triaceticacid (NOTA)-tripolyethylene glycol (PEG3)-Duramycin (Al[18F]F-NOTA-PEG3-Duramycin) positron emission tomography (PET) for imaging of rat hepatic fibrosis. PROCEDURES Hepatic fibrosis rat models were injected with thioacetamide (TAA), control rats received saline (n = 12 per group). Rats in the two groups underwent PET imaging using Al[18F]F-NOTA-PEG3-Duramycin and [18F]FDG at multiple time points (2, 4, 6, and 8 weeks after TAA or saline treatment). Between-group differences in the apoptosis rate, fibrotic activity, and liver uptake of Al[18F]F-NOTA-PEG3-Duramycin or [18F]FDG were assessed using Student's t-test. Imaging results were cross-validated using histopathology detection and Pearson's correlation test was used to assess the association relationships between radioactive uptake value and quantified histopathological data. RESULTS Compared with control group at multiple time points, each TAA group showed a higher radioactive liver uptake of Al[18F]F-NOTA-PEG3-Duramycin (each P < 0.05). Furthermore, the increase in the liver uptake of Al[18F]F-NOTA-PEG3-Duramycin was proportional to the progression of fibrosis (R2 = 0.8846, P < 0.001) and apoptosis rate (R2 = 0.9208, P < 0.001) in the TAA group. Meanwhile, there were also between-group differences in [18F]FDG uptake in each phase (P < 0.05), however, no relationship between [18F]FDG uptake and the fibrotic activity was observed. CONCLUSIONS Al[18F]F-NOTA-PEG3-Duramycin PET/CT could be applied to monitor the progression of liver fibrosis, whereas [18F]FDG PET/CT could not. Implications of this work for noninvasive diagnosis of liver fibrosis, assessment of fibrotic activity, and evaluation of antifibrotic therapy are expected.

Abstract
Purpose: N-(2-[18F]fluoropropionyl)-L-glutamate ([18F]FPGLU) for hepatocellular carcinoma (HCC) imaging has been performed in our previous studies, but its radiosynthesis method and stability in vivo need to be improved. Hence, we evaluated the synthesis and biological properties of a simple [18F]-labeled glutamate analog, [18F]AlF-1,4,7-triazacyclononane-1,4,7-triacetic-acid-2-S-(4-isothiocyanatobenzyl)-l-glutamate ([18F]AlF-NOTA-NSC-GLU), for HCC imaging. Procedures: [18F]AlF-NOTA-NSC-GLU was synthesized via a one-step reaction sequence from NOTA-NSC-GLU. In order to investigate the imaging value of [18F]AlF-NOTA-NSC-GLU in HCC, we conducted positron emission tomography/computed tomography (PET/CT) imaging and competitive binding of [18F]AlF-NOTA-NSC-GLU in human Hep3B tumor-bearing mice. The transport mechanism of [18F]AlF-NOTA-NSC-GLU was determined by competitive inhibition and protein incorporation experiments in vitro. Results: [18F]AlF-NOTA-NSC-GLU was prepared with an overall radiochemical yield of 29.3 ± 5.6% (n = 10) without decay correction within 20 min. In vitro competitive inhibition experiments demonstrated that the Na+-dependent systems XAG-, B0+, ASC, and minor XC- were involved in the uptake of [18F]AlF-NOTA-NSC-GLU, with the Na+-dependent system XAG- possibly playing a more dominant role. Protein incorporation studies of the Hep3B human hepatoma cell line showed almost no protein incorporation. Micro-PET/CT imaging with [18F]AlF-NOTA-NSC-GLU showed good tumor-to-background contrast in Hep3B human hepatoma-bearing mouse models. After [18F]AlF-NOTA-NSC-GLU injection, the tumor-to-liver uptake ratio of [18F]AlF-NOTA-NSC-GLU was 2.06 ± 0.17 at 30 min post-injection. In vivo competitive binding experiments showed that the tumor-to-liver uptake ratio decreased with the addition of inhibitors to block the XAG system. Conclusions: We have successfully synthesized [18F]AlF-NOTA-NSC-GLU as a novel PET tracer with good radiochemical yield and high radiochemical purity. Our findings indicate that [18F]AlF-NOTA-NSC-GLU may be a potential candidate for HCC imaging. Also, a further biological evaluation is underway.

Abstract
Non-small cell lung cancer (NSCLC) is one of the most devastating cancers with high mortality worldwide. By inhibiting the activity of specific molecular targets in the cancer cells, tyrosine kinase inhibitors (TKIs) have become a standard treatment in combating NSCLC. Tepotinib hydrochloride is an orally bioavailable, mesenchymal-epithelial transition (MET) TKI developed mainly for selected NSCLC patients with METex14 skipping mutations. Tepotinib demonstrated durable clinical response in phase II clinical trials, which led to its approval for use in Japan and breakthrough therapy designation and accelerated approval in the U.S. These progresses highlighted tepotinib as a promising candidate for NSCLC patients. This review summarizes the pharmacological profile of tepotinib, preclinical studies and landmark clinical trials of tepotinib. In addition, we share our perspectives on the future direction of tepotinib as a novel anticancer drug.

Abstract
BACKGROUND AND PURPOSE The clinical practice of three-dimensional TOF-MRA, despite its capability in brain artery assessment, has been hampered by the relatively long scan time, while recent developments in fast imaging techniques with random undersampling has shed light on an improved balance between image quality and imaging speed. Our aim was to evaluate the effectiveness of TOF-MRA accelerated by compressed sensitivity encoding and to identify the optimal acceleration factors for routine clinical use. MATERIALS AND METHODS One hundred subjects, enrolled at 5 centers, underwent 8 brain TOF-MRA sequences: 5 sequences using compressed sensitivity encoding with acceleration factors of 2, 4, 6, 8, and 10 (CS2, CS4, CS6, CS8, and CS10), 2 using sensitivity encoding with factors of 2 and 4 (SF2 and SF4), and 1 without acceleration as a reference sequence (RS). Five large arteries, 6 medium arteries, and 6 small arteries were evaluated quantitatively (reconstructed signal intensity, structural similarity, contrast ratio) and qualitatively (scores on arteries, artifacts, overall image quality, and diagnostic confidence for aneurysm and stenosis). Comparisons were performed among the 8 sequences. RESULTS The quantitative measurements showed that the reconstructed signal intensities of the assessed arteries and the structural similarity consistently decreased as the compressed sensitivity encoding acceleration factor increased, and no significant difference was found for the contrast ratios in pair-wise comparisons among SF2, CS2, and CS4. Qualitative evaluations showed no significant difference in pair-wise comparisons among RS, SF2, and CS2 (P > .05). The visualization of all the assessed arteries was acceptable for CS2 and CS4, while 2 small arteries in images of CS6 were not reliably displayed, and the visualization of large arteries was acceptable in images of CS8 and CS10. CONCLUSIONS CS4 is recommended for routine brain TOF-MRA with balanced image quality and acquisition time; CS6, for examinations when small arteries are not evaluated; and CS10, for fast visualization of large arteries.

Abstract
OBJECTIVE Osteoarthritis (OA) is a common disease in the elderly and seriously affects the quality of life of patients. The purpose of this study was to explore the protective effect of Fibulin-5 on articular chondrocytes and its mechanism of action. PATIENTS AND METHODS Articular cartilage tissues from patients with OA and normal people were selected and tested for differences in Fibulin-5 expression. In addition, human chondrocytes were cultured, and the effects of Fibulin-5 on the extracellular matrix (ECM) of chondrocytes and the level of inflammation were examined by means of cell transfection and cytokine intervention. SKL2001, an agonist of the Wnt/β-catenin signaling pathway, was used to validate the mechanism of action of Fibulin-5 to protect chondrocytes. RESULTS Fibulin-5 was lowly expressed in the cartilage tissue of patients with OA. Overexpression of Fibulin-5 significantly increased the expressions of ECM collagen II and aggrecan in chondrocytes, while decreasing the expressions of MMP-3 and MMP-13. In addition, Fibulin-5 reduced IL-1β-induced inflammation of chondrocytes, as well as expressions of IL-6, IL-8, and TNF-α. Overexpression of Fibulin-5 also reduced the activity of Wnt/β-catenin signaling pathway, and activation of Wnt/β-catenin signaling pathway attenuated the protective effects of Fibulin-5 on the ECM of chondrocytes. CONCLUSIONS Fibulin-5 can protect the ECM of chondrocytes and reduce the inflammatory response of chondrocytes by inhibiting the Wnt/β-catenin signaling pathway.

Abstract
Hepatitis B virus (HBV) infection remains a major global health problem. It is therefore imperative to develop drugs for anti-hepatitis B with high-efficiency and low toxicity. Attracted by the observations and evidence that the symptoms of some patients from the Southern Fujian, China, suffering from hepatitis B were alleviated after daily eating an edible marine mollusk, Thais clavigera (Küster 1860) (TCK). Water-soluble polysaccharide from TCK (TCKP1) was isolated and characterized. The anti-HBV activity of TCKP1 and its regulatory pathway were investigated on both HepG2.2.15 cell line and HBV transgenic mice. The data obtained from in vitro studies showed that TCKP1 significantly enhanced the production of IFN-α, and reduced the level of HBV antigens and HBV DNA in the supernatants of HepG2.2.15 cells in a dose-dependent manner with low cytotoxicity. The result of the study on the HBV transgenic mice further revealed that TCKP1 significantly decreased the level of transaminases, HBsAg, HBeAg, and HBV DNA in the serum, as well as HBsAg, HBeAg, HBV DNA, and HBV RNA in the liver of HBV transgenic (HBV-Tg) mice. Furthermore, TCKP1 exhibited equivalent inhibitory effect with the positive control tenofovir alafenamide (TAF) on the markers above except for HBV DNA even in low dosage in a mouse model. However, the TCKP1 high-dose group displayed stronger inhibition of transaminases and liver HBsAg, HBeAg, and HBV RNA when compared with those of TAF. Meanwhile, inflammation of the liver was, by pathological observation, relieved in a dose-dependent manner after being treated with TCKP1. In addition, elevated levels of interleukin-12 (IL-12) and interferon γ (IFN-γ), and reduced level of interleukin-4 (IL-4) in the serum were observed, indicating that the anti-HBV effect of TCKP1 was achieved by potentiating immunocyte function and regulating the balance of Th1/Th2 cytokines.

Abstract
AIM To characterise symptomatic intracranial plaque without substantial stenosis using three-dimensional (3D) high-resolution contrast-enhanced black-blood magnetic resonance imaging (BBMRI) and to determine plaque features associated with recent cerebrovascular events. MATERIALS AND METHODS The institutional review board approved this retrospective study. The case notes from patients with evidence of intracranial atherosclerosis in a large intracranial artery with preceding BBMRI were reviewed retrospectively. Symptomatic and asymptomatic plaques with substantial luminal stenosis (<50%) were matched by plaque location and patient age. All MRI images were de-identified and interpreted by two neuroradiologists who were blinded to the history of symptoms. Qualitative analyses including the presence of intraplaque haemorrhage (IPH), eccentricity, surface irregularity, and grade of plaque enhancement were recorded. Quantitative analyses including normal wall index and degree of contrast enhancement were calculated. Multivariate regression analysis was performed to identify the association with cerebrovascular ischaemic events. RESULTS A total of 38 pairs of symptomatic and asymptomatic plaques from 74 patients were analysed. Compared to asymptomatic plaques, symptomatic plaques demonstrated higher degree of contrast enhancement (29.77 ± 19.23 versus 18.21 ± 12.18%, p=0.039) and presence of IPH (26% versus 8%, p=0.032). No significant differences were detected regarding eccentricity, surface irregularity, and normal wall index. Events were associated with contrast enhancement (OR, 1.212; 95% confidence interval [CI], 1.086-1.352) after controlling for age, sex, cardiovascular risk factors, and stenosis degree. IPH was not associated with events. CONCLUSION Contrast enhancement in the intracranial plaque without substantial stenosis is associated with previous events, and may serve as the vulnerable feature, thereby stratifying stroke risk not achievable by luminal stenosis.

Abstract
OBJECTIVE To explore the effects of micro ribonucleic acid (miR)-188 on proliferation and apoptosis of lung adenocarcinoma (LUAD) cells, and its potential mechanism. MATERIALS AND METHODS The expression level of miR-188 in LUAD cell lines was detected via quantitative Real Time-Polymerase Chain Reaction (PCR). The effects of miR-188 overexpression on proliferation and apoptosis of A549 cells were detected using methyl thiazolyl tetrazolium (MTT) assay, colony formation assay, and flow cytometry. The potential targets for miR-188 were predicted using the TargetScan Human database, and the interaction between miR-188 and target gene was determined through Dual-Luciferase reporter assay. Moreover, the associations of miR-188 and sine oculis homeobox homolog 1 (SIX1) with the extracellular signal-regulated kinase (ERK) pathway were detected via Western blotting. RESULTS The expression of miR-188 significantly declined in LUAD cell lines (p<0.05). The overexpression of miR-188 significantly reduced the proliferation rate of A549 cells and increased the percentage of apoptotic A549 cells (p<0.05). Similarly, it was found in colony formation assay that the overexpression of miR-188 inhibited the colony formation ability of A549 cells most significantly (p<0.05). SIX1 was a direct target for miR-188, and its mRNA and protein expressions were downregulated by the overexpression of miR-188. The remarkable downregulation of phosphorylated ERK was observed in A549 cells overexpressing miR-188, while the decline in phosphorylated ERK was reversed in A549 cells overexpressing miR-188 and SIX1. CONCLUSIONS The expression of miR-188 is downregulated in LUAD cell lines. The overexpression of miR-188 inhibits proliferation and promotes apoptosis of LUAD cells, whose functional mechanism may be related to its regulation on the ERK signaling pathway by targeting SIX1.

Abstract
OBJECTIVE Abnormal expression of micro ribonucleic acids (miRNAs) has become an important marker of cancer. However, the exact molecular mechanisms of miRNAs were not very clear. Here, we decided to investigate the miR-19 effect and molecular mechanism on pancreatic cancer, which was blank until now. PATIENTS AND METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) analysis was applied for testing miR-19 and gene of phosphate and tensin homolog deleted on chromosome ten (PTEN) expression. Western blot was used for detecting the protein expression. Methyl thiazolyl tetrazolium (MTT) assay and transwell assay were carried out to measure cell proliferation, invasion, and migration. RESULTS We showed that miR-19 expression was increased in cancerous tissues and was associated with the survival of patients, tumor node metastasis (TNM) stage, tumor size, and lymph node metastasis. MiR-19 mimic enhanced cell proliferation, invasion, and migration, while suppressing miR-19 cell progression was suppressed. With the help of TargetScanHuman and luciferase reporter assay, we verified PTEN as a specific target of miR-19. Moreover, PTEN expression was reduced by miR-19 mimic and was increased by miR-19 inhibitor. We next found that PTEN was elevated in cancerous tissues and its expression was negatively correlated with miR-19 expression. Furthermore, miR-19 regulated cell progression via activating phosphatidylinositol 3-hydroxy kinase/protein kinase B (PI3K/AKT) signaling pathway. CONCLUSIONS We demonstrated that miR-19 facilitated cell progression through modulating PI3K/AKT signaling pathway by targeting PTEN, which provided a potential therapeutic target for pancreatic cancer patients.

Abstract
Objective: To investigate the effect of six degree of freedom (6-DOF) bed combined with cone beam computed tomography (CBCT) in the on-line correction of setup errors in patients with primary rectal cancer. Methods: The clinicopathological data of 17 patients with primary rectal cancer in Department of Radiotherapy, Third Hospital of Peking University from July 2013 to January 2014 were collected. There were 14 males and 3 females, a median age of 65 years. The difference of CBCT and 6-DOF bed combined with CBCT online correction of patients with positioning error were retrospectively analyzed. Results: Before position correction, the first CBCT verification of setup errors in the three translation directions including X (left and right), Y (in and out) and Z (up and down) directions were (0.06±0.25) cm, (0.13±0.40) cm and (-0.28±0.31) cm, respectively. The setup errors of RX (rotation pitch), RY(rolling) and RZ (left and right rotation) directions were (0.62±1.15)°, (-0.19±0.99)°, and (-0.34 ± 0.84)°, respectively . After correction of IGRT combined with six freedom of bed, the setup errors of translation X, Y and Z were (0.01±0.09) cm, (-0.01±0.05) cm and (-0.03±0.08) cm, respectively, and the setup errors of rotation RX, RY and RZ directions were (-0.16±0.40)°, (0.36±0.31)°and (-0.01±0.25)°, respectively. There were significant differences in translation direction (X, Y and Z direction) and rotation direction (Rx, RY and RZ) before and after 6-DOF bed combined with CBCT correction (all P<0.05). In the translation direction, the higher frequency range of Z-direction error value was 0.20-0.79 cm. In the rotation direction, the frequency range of error in Rx direction was 0.20°-2.99°. There was no significant difference between bone mode and gray scale model registration (P>0.05). With the progress of radiotherapy, the setup errors of X, Z, Rx, RY and RZ directions increased except Y direction. Conclusions: In radiotherapy, six freedom bed combined with CBCT is helpful to correct the setup errors of patients with primary rectal cancer. Six freedom bed may be used to correct the setup errors of patients with primary rectal cancer online. Image-guided radiation therapy (IGRT) is recommended for bone pattern registration in patients with rectal cancer.

Abstract
Objectives With the prolonged survival time of AIDS patients, complications of various systems and organs of HIV infection are increasingly prominent. These diseases have become the major factors influencing the quality of life and prognosis of HIV‐infected persons, and multidisciplinary cooperation treatment is urgently needed. Methods The Chinese HIV/AIDS Clinical Trial Network has conducted a series of multicentre clinical cohort studies over the past 16 years, in which studies related to people living with HIV systemic complications. Based on the results of previous studies, this review establishes the complications of Chinese people living with HIV after long‐term cART. Results HIV’s direct damage to human cells, chronic abnormal inflammatory activation after HIV infection, long‐term drug side effects caused by cART and persistent reservoirs cause systemic complications in people living with HIV. We summarised the clinical characteristics of the complications of HIV infection in China from the aspects of the liver, cardiovascular, the nervous system, the kidney, bone metabolism, blood glucose, and lipid metabolism. Conclusions The management of the complications of HIV infection is a major link in improving the survival treatment and prognosis of patients in the future. The joint participation of doctors from different departments of general hospitals in the management of comorbidities is the main theme for future improvement of quality of life and prognosis for people living with HIV.

In this work, we show an obvious evidence of nondestructive Raman spectra for the structural transition, i.e., the existence of a charge density wave (CDW) in monolayer 2H-TaS2, which can exhibit a much higher transition temperature than bulk and results in additional vibrational modes, indicating strong interactions with light. Furthermore, we reveal that the degenerate breath and wiggle modes of 2H-TaS2 originated from the periodic lattice distortion can be probed using the optical methods. Since recently several light-tunable devices have been proposed based on the CDW phase transition of 1 T-TaS2, our study and in particular, the theoretical results will be very helpful for understanding and designing electronic devices based on the CDW of 2H-TaS2.

Abstract
Objective: To study the effects on learning and memory, mitochondrial energy metabolism and ATPase activity of hippocampus in mice with subacute exposure to n-hexane. Methods: The SPF 40 Kunming mice were randomly divided into low, middle and high dose groups and control groups according to different dosages. Each group consisted of 10 mice. The mice were given n-hexane by gavage, the mice in the low, middle and high dose groups were given 0.2 ml/d of n-hexane at concentrations of 500, 1000 and 2000 mg/kg respectively, while the mice in the control group were given 0.2 ml/d of cooking oil once a day for 28 days. The y-type maze test, the activity of ATP Enzyme, mitochondrial respiratory chain enzyme complex Ⅰ-IV, the mrna of mitochondrial fusion gene (MFn1, Mfn2) and fission gene (FIs1) in brain tissues were performed. Results: Except for the wrong reaction times of low-dose exposure group in the first test, there existed significantly different in the first and second Y-maze tests in exposure groups and control group (P<0.05) ; in low, middle and high-dose group, the Na(+)-K(+)-ATPase activities were (8.27±2.65) , (5.38±1.55) , (3.55±1.69) μmol/gprot/h, and Ca(2+)-Mg(2+)-ATPase activities were (10.32±2.96) , (7.19±1.94) and (4.49±1.33) μmol/gprot/h, respectively. Compared with those in control group, the activities of Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase decreased significantly in middle-dose group and high-dose group (P<0.05) . Compared with those in control group, the activities of mitochondrial respiratory chain enzyme complex I-IV in each dose group were significantly decreased (P<0.05) . The expressions of Mfn1mRNA and Mfn2mRNA in each dose group was significantly lower than those in control group (P<0.05) . Conclusion: Subacute exposure to n-hexane can result in the decrease of activities of mitochondrial respiratory chain enzyme complex in hippocampus of mice, which may lead to the disorder of mitochondrial energy metabolism by the decrease of ATPase activity and the imbalance of mitochondrial fusion-division, which must be one of the mechanisms of impairment of learning and memory of mice induced by n-hexane.

Abstract
Fast radio bursts (FRBs) are millisecond-duration radio transients of unknown physical origin observed at extragalactic distances1-3. It has long been speculated that magnetars are the engine powering repeating bursts from FRB sources4-13, but no convincing evidence has been collected so far14. Recently, the Galactic magnetar SRG 1935+2154 entered an active phase by emitting intense soft γ-ray bursts15. One FRB-like event with two peaks (FRB 200428) and a luminosity slightly lower than the faintest extragalactic FRBs was detected from the source, in association with a soft γ-ray/hard-X-ray flare18-21. Here we report an eight-hour targeted radio observational campaign comprising four sessions and assisted by multi-wavelength (optical and hard-X-ray) data. During the third session, 29 soft-γ-ray repeater (SGR) bursts were detected in γ-ray energies. Throughout the observing period, we detected no single dispersed pulsed emission coincident with the arrivals of SGR bursts, but unfortunately we were not observing when the FRB was detected. The non-detection places a fluence upper limit that is eight orders of magnitude lower than the fluence of FRB 200428. Our results suggest that FRB-SGR burst associations are rare. FRBs may be highly relativistic and geometrically beamed, or FRB-like events associated with SGR bursts may have narrow spectra and characteristic frequencies outside the observed band. It is also possible that the physical conditions required to achieve coherent radiation in SGR bursts are difficult to satisfy, and that only under extreme conditions could an FRB be associated with an SGR burst.

Abstract
OBJECTIVE The aim of this study was to explore the influences of long non-coding ribonucleic acid (lncRNA) homeobox transcript antisense intergenic RNA (HOTAIR) on the proliferation and apoptosis of myeloma cells and its molecular mechanism. MATERIALS AND METHODS The myeloma cells were randomly divided into three groups, including: group A (myeloma cell group), group B [HOTAIR-small-interfering RNA (siRNA) group], and group C (HOTAIR negative control group). The Reverse Transcription-Polymerase Chain Reaction (RT-PCR) was performed to detect the expression of lncRNA HOTAIR in myeloma cells. The flow cytometry was adopted to determine the apoptosis of myeloma cells. Meanwhile, the protein expression of nuclear factor-kappa-light-chain-enhancer of activated B cells (NF-κB) was detected via Western blotting. In addition, the activity of the myeloma cells was measured using methyl thiazolyl tetrazolium (MTT) assay. RESULTS The expression of HOTAIR in group A, group B, and group C was (2.19 ± 0.33), (1.37 ± 0.25), and (2.51 ± 0.27), respectively. Compared with group A and group C, the expression of HOTAIR was significantly downregulated in group B, in which the cells interfered with siRNAs. The expression of HOTAIR was significantly higher in group C than group A and group B (p<0.05). HOTAIR expression reached the highest level in group C, followed by group A and group B, respectively. The results of MTT indicated that the activity of the myeloma cells significantly increased at 24 h, 48 h, and 72 h in group C when compared with group A and group B. However, the activity of the myeloma cells was relatively low in group B, showing a slow rising trend. The activity of myeloma cells in group A remarkably increased when compared with group B, but it was lower than group C. Furthermore, the activity of the myeloma cells was higher in group C than group B (p<0.05). Western blotting indicated that the protein expression of NF-κB in group A, group B, and group C was (0.79 ± 0.22), (0.51 ± 0.17), and (0.95 ± 0.31), respectively. Compared with group A and group C, the protein expression of NF-κB was significantly downregulated in group B (the cells interfered with siRNAs) (p<0.05). Meanwhile, the protein expression of NF-κB was markedly higher in group C than in group A and group B (p<0.05). The protein expression of NF-κB was the highest in the cells of group C. Flow cytometry demonstrated that the apoptosis rate in group A, group B, and group C was (9.57 ± 1.71), (20.33 ± 1.63), and (8.74 ± 1.23), respectively. Compared with group A and group C, the apoptosis was significantly elevated in group B, in which the cells interfered with siRNAs (p<0.05). Compared with group A, the number of apoptotic myeloma cells significantly decreased in group C (p<0.05). CONCLUSIONS LncRNA HOTAIR activates the expression of NF-κB in myeloma cells and promotes the proliferation of myeloma cells.

Abstract
One 24 years old female patient who suffered extremely severe burn in the third trimester of pregnancy was admitted to the Department of Burns and Skin Repair Surgery of the Third Affiliated Hospital of Wenzhou Medical University on 9th May, 2015. Intrauterine distress occurred after injury and stillbirth was confirmed within 12 hours. In cooperation with the obstetrician, the labor was induced on post injury day (PID) 5. Septic shock and multiple organ dysfunction syndrome occurred on PID 8. Through treatments including anti-infection, ventilator-assisted ventilation, cardiotonic diuresis, and escharectomy and skin grafting, the patient was finally cured. This case indicates that it is crucial to grasp the right time and choose a reasonable induction of labor to deal with stillbirth. The scheme of transvaginal induction of labor after shock is a worthy question to explore. The main characteristics of this patient include the extreme paroxysmal changes in breath, circulation, and urine volume within 24 hours after induced labor, which should be monitored dynamically for effective and timely adjustment of respiratory circulation support. This may be another key point for the rescue of this type of patient. To seize the opportunities to perform escharectomy, cover the wound with xenogenic skin graft, and perform skin grafting in time for wound repair remain the top priority.

Abstract
PURPOSE This study aimed to determine the susceptibility and the changes of bacterial agents of chronic dacryocystitis and determine the risk factors for bacterial prevalence and drug sensitivity to provide a reference for clinical selection of antibiotics. METHODS A case-control study was conducted using 112 patients with chronic dacryocystitis and 112 patients with non-infectious ophthalmopathy between August 2017 and April 2018. Lacrimal and conjunctival sac secretions were cultured for aerobic and anaerobic bacteria. Forty-five patients with chronic dacryocystitis between November 2014 and November 2015 were also included. RESULTS Positive bacterial cultures were obtained from 61.9% and 50.9% of chronic dacryocystitis and non-infectious ophthalmopathy patients, but the detection rates for pathogenic bacteria were 18.3% and 2.7%, respectively (P > 0.001). Gram-negative and anaerobic bacteria were significantly more prevalent in the patient group compared with the control group (P = 0.001 and 0.005, respectively). Bacteria were detected at a significantly higher rate in patients with irritant symptoms (itch or foreign-body sensation) than in those without (OR = 9.333, P = 0.002), particularly Staphylococcus (OR = 9.783, P = 0.002). 11.6% (10/86) and 55.8% (48/86) showed resistance to levofloxacin and tobramycin, respectively. Compared with three years ago, the detection rate for Gram-positive cocci decreased from 51.1% to 27.8% (χ2 = 8.054, P = 0.005) CONCLUSIONS: Gram-positive cocci, Gram-negative bacilli, and anaerobic bacteria were the predominant pathogens. The prevalence of Gram-positive bacteria in cases of chronic dacryocystitis is decreasing.

Abstract
Objective: To investigate the epidemiological characteristics and transmission chain of COVID-19 in two families, and to provide scientific evidence for effective prevention and control measures. Methods: Field epidemiological investigation was conducted for the COVID-19 cases occurred in two families and the close contacts in a county of Baotou city in Inner Mongolia Autonomous Region. Descriptive statistical analysis on epidemiological data was conducted. Results: The infection source of the COVID-19 cases in the two families was a man who had living history in Wuhan. After his return, his parents were infected by him. A few days later, the members of a neighbor family were found to be infected, and relatives of this family were also infected after dining together repeatedly. Finally, ten confirmed cases and three suspected cases of COVID-19 were detected in the two families. Conclusions: Human-to-human transmission of COVID-19 can occur not only in a family but also in neighborhoods. The cases in two families had close relationship, indicating the necessity to strengthen the health education about COVID-19 prevention and control and the management of groups at high risk to reduce the incidence of COVID-19 in families and neighborhoods.

Abstract
Objective: To understand the provision of preventive medicine curriculum system in the training programs of clinical medicine in the era of Healthy China. Methods: A total of 36 training programs of clinical medicine were selected from different areas of China for a statistical analysis on their basic information, involvement of concept of preventive medicine in program objectives, and provision of preventive medicine curriculum system. Results: Of all the 36 training programs of clinical medicine, 22(61%) have no mentions of prevention medicine in their program objectives; only one university's training program states preventive medicine together with basic medicine and clinical medicine as one of the three main disciplines. The total class hours for the core courses of preventive medicine (hygiene, medical statistics, epidemiology, evidence-based medicine, and social medicine) range from 80 to 252, with an average of (156.7±43.2) hours. The average percentage of class hours for preventive medicine courses among the total class hours is 4.3%±1.1% (range: 2.5%-7.5%), and obvious differences exist among universities. Conclusions: In current training programs of clinical medicine, the proportion of prevention medicine curriculum is insufficient, the percentage of hours for preventive medicine course is very low, and the differences among various universities are obvious. It is urgently needed to strengthen preventive medicine curriculum in training programs for clinical medical students in new era. It is suggested to further promote the concept of putting prevention first, improve the curriculum system of clinical medicine, intensify the integrated development preventive medicine and clinical medicine and pay attention to clinical research ability enhancement for the further improvement of training program of clinical medicine.

Abstract
PURPOSE The supply of non-iodized salt and the water improvement project have been conducted to reduce the iodine concentration in drinking water in areas with elevated water iodine. We aimed to assess the impact of water iodine concentration (WIC) on the iodine intake of pregnant women in areas with restricted iodized salt supply, and determine the cutoff values of WIC in areas with non-iodized salt supply. METHODS Overall, 534 pregnant women who attended routine antenatal outpatient visits in Zibo Maternal and Child Health Hospital in Gaoqing County were recruited. The 24-h urine iodine excretion (UIE) in 534 samples and the iodine concentration in 534 drinking water samples were estimated. Urinary iodine excretion, daily iodine intake, and daily iodine intake from drinking water (WII) were calculated. The relationship between WIC and daily iodine take was analyzed. RESULTS The median WIC, spot urine iodine concentration (UIC), and 24-h UIE were 17 (6, 226) μg/L, 145 (88, 267) μg/L, and 190 (110, 390) μg/day, respectively. A significant positive correlation was found between WIC and UIE (R2 = 0.265, p < 0.001) and UIC (R2 = 0.261, p < 0.001). The contribution rate of WII to total iodine intake increased from 3.0% in the group with WIC of < 10 μg/L to 45.7% in the group with WIC of 50-99 μg/L. CONCLUSION The iodine content in drinking water is the major iodine source in pregnant women living in high-water iodine areas where iodized salt supply is restricted. The contribution rate of daily iodine intake from drinking water increases with the increase in water iodine concentration.

Abstract
OBJECTIVE This study aims to understand the attitude of health-care professionals (HPs) in mainland China toward menopause management (MM) as well as the knowledge they have received regarding MM during training. METHODS An anonymous survey recruited 3709 medical workers nationwide (including physicians, orthopedists, obstetricians and gynecologists, and general practitioners) through online surveys and on-site interviews at professional meetings. RESULTS Of the 3709 questionnaires completed, 3426 questionnaires met the inclusion criteria. Of the participants, 1532 HPs had not received menopause management training (MMT) in nearly 1 year. Among the residents and physician assistants, 103 reported they were not familiar with MM. Satisfyingly, 98.3% of HPs considered it very important or essential to accept MM. Although most interviewees replied some correct menopausal knowledge, nearly half of them could not correctly identify the contraindications for menopause hormone therapy (MHT). Additionally, 73.1% of HPs would advise patients with premature ovarian insufficiency to receive hormone replacement therapy at least until the average age of menopause. CONCLUSION This survey indicated that HPs have some knowledge regarding MM, but a gap remains to master the basic theory of MHT. In order to manage the growing menopausal population in China, creating more in-depth educational MMT programs for HPs is necessary.

Abstract
This report quantifies the influence of inorganic fullerene-like tungsten disulfide (IF-WS2) nanoparticles on the pool-boiling performance of R134a/polyolester mixtures on a commercial (Turbo-ESP) boiling surface. Tungsten disulfide nanoparticles, of roughly 150 nm, were used at a 15% mass fraction in a base polyolester lubricant to produce the test nanolubricant. The nanolubricant was mixed with R134a at a 1% mass fraction. The study showed that the nanolubricant caused an average 37% degradation in the boiling heat flux as compared to R134a/neat-lubricant boiling on a reentrant cavity surface at the same superheat. Similarly, boiling with R134a/neat-lubricant caused, on average, a 27% degradation in the boiling heat flux as compared to pure R134a boiling and the same superheat. An analysis was presented which showed that the nanoparticles were too large and too dense to promote a boiling enhancement. In addition, the fullerene-like structure and the large size encouraged nanoparticle settling, which presumably filled cavities of the boiling surface leading to additional boiling degradations.

Abstract
Abstract
Introduction
Kleine-Levin Syndrome (KLS) is a rare disorder affecting adolescents and characterized by relapsing-remitting episodes of severe hypersomnia, cognitive impairment, and behavioral disturbances such as hyperphagia and sexual disinhibition. Pathophysiology is unknown, although imaging studies indicate decreased activity in hypothalamic/thalamic areas and in cortical areas during episodes. Familial occurrence is increased, and risk is associated with reports of complicated birth.
Methods
A worldwide Genome wide association (GWA) study was conducted in 673 KLS patients and ethnically matched 15,341 control individuals.
Results
We found a strong genome-wide significant association (OR=1.48 at rs150168018, p=8.6x10-9) with 24 single nucleotide polymorphisms (SNPs) encompassing a 35kb region located in the 5’ region of TRANK1 gene previously associated with bipolar disorder and schizophrenia. Strikingly, KLS cases with TRANK1 had statistically increased reports of difficult birth. As perinatal outcomes have dramatically improved over the last 40 years, we further stratified our sample by birth years, and found that recent cases had a significantly reduced TRANK1 association. These findings were confirmed in an independent replication cohort of 171 new patients where polygenic risk scores constructed on the discovery cohort replicated (r2=0.15; p<2.7x10-22 at p=0.1 threshold) and the TRANK1 association was found to be dependent on reports of birth difficulties (OR=1.54, p=0.01 versus OR=1.12, p=0.4). Pathway analysis of the overall GWAS association revealed significant association (p=0.02) with 19 genes in a pathway modulating rhythmic behaviors.
Conclusion
Our results demonstrate links between hypersomnia, behavioral rhythmicity and bipolar disorder and indicate that a polymorphism in the TRANK1 region affect brain development in the presence of a perinatal injury, with pathophysiological consequences such as KLS, bipolar disorder and schizophrenia.

Abstract
Introduction
Healthy sleep promotes cognitive functioning and is associated with better academic performance, whereas insufficient, poor, and inconsistent sleep schedules are associated with poor school performance. Several studies have identified gender differences in the timing, duration, and quality of sleep in adolescence, with adolescent girls having poorer sleep compared to adolescent boys, yet research shows that girls outperform boys academically. This could be because sleep might not affect all subjects similarly and previous studies regarding sleep and academic performance combined both genders. The goal of the present study was to determine which aspects of academic performance are specifically associated with short or poor sleep in typically developing adolescents girls.
Methods
80 adolescent girls aged 12-17 years participated in the study. Sleep was assessed in the home environment for five consecutive weeknights using actigraphy. Academic performance was assessed using report card grades.
Results
Hierarchical regression analyses adjusted for age, pubertal status, and socioeconomic status revealed that longer average sleep time was significantly associated with higher grades in mathematics. No significant associations were found between sleep variables and grades in other subjects.
Conclusion
Longer average weekday sleep duration is associated with better mathematics grades in typically developing adolescent girls.

Introduction
The 2009 Pandemrix influenza A pH1N1 vaccine has been linked to an increased number of Narcolepsy type I onsets in children across Europe whereas administration of a very similar adjuvanted vaccine, Arepanrix, had little effects in Canada. One possible explanation for the difference may be vaccine composition differences that could modify peptide binding to narcolepsy associated HLA-DQ0602 allele, as viral extracts for these two vaccines used distinct processes in different factories. Other explanations may involve differences in vaccination timing in relation to the pandemic H1N1 infection wave, or other environmental factors. We have previously compared the amino acid sequence of the Hemagglutinin (HA) component of the Pandemrix and the 2010 Arepanrix vaccine, finding possible contributors, but excluding most of these after DQ0602-tetramer analysis of T cell reactivity in narcolepsy versus controls.
Methods
Mass spectrometric characterization of multiple additional batches of Pandemrix and Arepanrix used during 2009 influenza pandemic vaccination campaign was performed.
Results
In addition to confirming previously published results such as increased deamidation of hemagglutinin (HA) (146N>D) in Pandemrix (p=2.1e-9), we identified novel differences, including a significant 2-fold post-translation deamidation increase in 277N in Arepanrix versus Pandemrix (p=0.032), together with increased 2-fold glycosylation in the 286-323 positions in Arepanrix (p=0.00036). The 277 N to D/isoD substitution is located in pocket 1 of the binding core of a strong binder NAGSGIIIS, (< 10% rank) for HLA-DQ0602 allele and abolishes epitope binding. The increased glycosylation in Arepanrix occurs in the immediate flanking area of the same 277N epitope and could also reduce DQ0602 presentation of the same epitope through differential binding and/or proteolysis of HA in this region of the molecules. As CD4 T cells recognizing this epitope have been reported to be significantly increased in narcolepsy versus DQ0602 controls, with possible mimicry with homologous hypocretin sequence.
Conclusion
These changes could explain why Arepanrix was less narcolepsy inducing. Confirmatory studies, as well as studies of all novel changes observed, are ongoing, but this is a promising result.
