Abstract
Different from most of the previous studies using light or photons, we use highly charged ions as projectiles to activate proton migration in the smallest saturated and unsaturated hydrocarbon molecules, i.e., CH4 and C2H2. The H3 + formation channel (H3 + + CH+) and isomerization channel (C+ + CH2 +), serving as indicators of proton migration, are observed in the fragmentation of CH4 and C2H2 dications. Corresponding kinematical information, i.e., kinetic energy release, is for the first time obtained in the collisions with highly charged ions. In particular, for the C+ + CH2 + channel, a new pathway is identified, which is tentatively attributed to the isomerization on high-lying states of acetylene dication. The kinetic energy release spectra for other two-body breakup channels are also determined and precursor dication states could thus be identified.

Abstract
AIMS/OBJECTIVES To investigate the underlying molecular mechanism of the patient's ABO typing discrepancy. BACKGROUND ABO typing discrepancy was frequently seen in patients due to different causes. In this study, ABO typing discrepancy was found in a 24-year-old man with arthralgia, whose forward ABO grouping was O and reverse ABO grouping was AB. Primary immunodeficiency disease was speculated in this patient, especially X-linked agammaglobulinemia (XLA). METHODS Immunoglobulins of all isotypes were detected using a specific protein analyser. Lymphocyte subgroups were analysed by flow cytometry. All 19 exons and boundaries of BTK gene were amplified by polymerase chain reaction (PCR), and all PCR products were sequenced by a DNA analyser. BTK protein in the leukocytes and platelets was detected by Western blot. RESULTS No B lymphocytes could be detected in the peripheral blood of the patient. A novel BTK gene variation, c.817G>T, in the exon 9 of BTK gene was discovered. No BTK protein expression could be detected in the leukocytes and platelets of the patient. CONCLUSIONS XLA could be occasionally discovered by ABO typing discrepancy in some cases because of the deficiency of reciprocal IgM anti-A and/or anti-B antibodies in the serum of the patient. Humoral immunodeficiency is one of the causes of ABO typing discrepancy.

Abstract
We theoretically study Ar8+-induced dissociation of C2H2 molecule at 1.2 MeV using the time-dependent density-functional theory non-adiabatically coupled to nuclear dynamics. We find that molecular dissociation depends strongly on the ionization at the initial stage and the collision configuration. A detailed analysis shows a correspondence between the charge state of [C2H2]q+ and the final fragments. A remarkable impact parameter effect provides deep insights of bond breakup and electronic transport. We analyze two typical sequential dissociation channels reported in experiments by tracking structural and electronic dynamics in real time. Our results provide better understanding of experiments. Moreover, the comparison between various exchange-correlation functionals reveals that electrons' correlation and self-interaction do not significantly impact the initial ionization and fragment distribution in the present study.

Abstract
SummaryThree to four percent of the world’s population has diabetes mellitus (DM), which leads to a markedly increased risk of blindness, renal failure, amputation and cardiovascular disease, and reduces average life expectancy by 10 or more years. However, the prevalence of this severe metabolic disease among patients with severe mental illness (SMI), including schizophrenia, bipolar disorder, schizoaffective disorder and major depressive disorder, is higher than in the general population and its impact on these individuals significantly greater. We reviewed the literature on what is currently known about the relationship between SMI and DM and report prevalence rates of DM type 2 as well as important individual lifestyle choices and side effects of antipsychotic and antidepressant treatment, which each account for much of the increased risk of this metabolic disease in these patients. However, the exact cause and effect relationships between the prescription of these medications and DM type 2 still remain to be elucidated.

Abstract
BACKGROUND & AIMS Single nucleotide polymorphisms could affect risk for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). We performed a germline copy number variation (CNV)-based genome-wide association study (GWAS) in populations of Chinese ancestry to search for germline CNVs that increase risk of HCC. METHODS We conducted a CNV-based GWAS of 1583 HCC cases (persons with chronic HBV infection and HCC) and 1540 controls (persons with chronic HBV infection without HCC) in Chinese populations. Identified candidates were expressed in L-02, HepG2, or TP53-/- or wild-type HCT116 cells, and knocked down with short hairpin RNAs in HepG2, Bel-7402, and SMMC-7721 cells; proliferation, colony formation, and apoptosis were measured. Formation of xenograft tumors from cell lines was monitored in nude mice. Subcellular localization of ribosome proteins and levels or activity of p53 were investigated by co-immunoprecipitation, immunofluorescence, and immunoblot analyses. Levels of small nucleolar RNA H/ACA box 18-like 5 (SNORA18L5) were quantified by quantitative reverse transcription polymerase chain reaction. RESULTS We identified a low-frequency duplication at chromosome 15q13.3 strongly associated with risk of HBV-related HCC (overall P = 3.17 × 10-8; odds ratio, 12.02). Copy numbers of the 15q13.3 duplication correlated with the expression of SNORA18L5 in liver tissues. Overexpression of SNORA18L5 increased HCC cell proliferation and growth of xenograft tumors in mice; knockdown reduced HCC proliferation and tumor growth. SNORA18L5 overexpression in HepG2 and SMMC-7721 cells inhibited p53-dependent cell cycle arrest and apoptosis. Overexpression of SNORA18L5 led to hyperactive ribosome biogenesis, increasing levels of mature 18S and 28S ribosomal RNAs and causing the ribosomal proteins RPL5 and RPL11 to stay in the nucleolus, which kept them from binding to MDM2. This resulted in increased MDM2-mediated ubiquitination and degradation of p53. Levels of SNORA18L5 were increased in HCC tissues compared with nontumor liver tissues and associated with shorter survival times of patients. CONCLUSIONS In a CNV-based GWAS, we associated duplication at 15q13.3 with increased risk of HBV-related HCC. We found SNORA18L5 at this location to promote HCC cell proliferation and tumor growth in mice. SNORA18L5 increases ribosome biogenesis, facilitates ribosomal RNA maturation, and alters localization of RPL5 and RPL11, allowing for increased MDM2-mediated proteolysis of p53 and cell cycle arrest.

Abstract
BACKGROUND AND PURPOSE Convolutional neural networks are a powerful technology for image recognition. This study evaluates a convolutional neural network optimized for the detection and quantification of intraparenchymal, epidural/subdural, and subarachnoid hemorrhages on noncontrast CT. MATERIALS AND METHODS This study was performed in 2 phases. First, a training cohort of all NCCTs acquired at a single institution between January 1, 2017, and July 31, 2017, was used to develop and cross-validate a custom hybrid 3D/2D mask ROI-based convolutional neural network architecture for hemorrhage evaluation. Second, the trained network was applied prospectively to all NCCTs ordered from the emergency department between February 1, 2018, and February 28, 2018, in an automated inference pipeline. Hemorrhage-detection accuracy, area under the curve, sensitivity, specificity, positive predictive value, and negative predictive value were assessed for full and balanced datasets and were further stratified by hemorrhage type and size. Quantification was assessed by the Dice score coefficient and the Pearson correlation. RESULTS A 10,159-examination training cohort (512,598 images; 901/8.1% hemorrhages) and an 862-examination test cohort (23,668 images; 82/12% hemorrhages) were used in this study. Accuracy, area under the curve, sensitivity, specificity, positive predictive value, and negative-predictive value for hemorrhage detection were 0.975, 0.983, 0.971, 0.975, 0.793, and 0.997 on training cohort cross-validation and 0.970, 0.981, 0.951, 0.973, 0.829, and 0.993 for the prospective test set. Dice scores for intraparenchymal hemorrhage, epidural/subdural hemorrhage, and SAH were 0.931, 0.863, and 0.772, respectively. CONCLUSIONS A customized deep learning tool is accurate in the detection and quantification of hemorrhage on NCCT. Demonstrated high performance on prospective NCCTs ordered from the emergency department suggests the clinical viability of the proposed deep learning tool.

Abstract
Hepatitis E virus (HEV) infection causes subclinical diseases, leading to high mortality (>25%) in pregnant women. HEV replication is aggressively escalated in pregnant women, especially in the third trimester of pregnancy. Oestrogen plays an important role in pregnancy. However, the pathogenesis of HEV in pregnant women or immunosuppressive pregnant women (such as HIV-infected or organ-transplanted pregnant women) remains unclear. We investigated the role of oestradiol in HEV infection in a cell culture system. HEV-infected pregnant women had significantly higher oestradiol levels compared with uninfected individuals. HEV infection was significantly increased in cells treated with analogues of oestradiol, diethylstilbestrol (DES) or 17β-oestradiol in a dose-dependent way. However, tamoxifen, an antagonist oestrogen, inhibited HEV replication. HEV infection inhibits oestrogen receptor (ER-α) expression. Immunofluorescence and co-immunoprecipitation assays indicated that ER-α interacted with the helicase of HEV ORF1 indirectly. More importantly, HEV infection was exacerbated in immunosuppressive cells treated with an inhibitor of PI3K-AKT-mTOR signal pathway (LY296004) and supplemented with pregnant women serum with high oestradiol simultaneously. These results strongly suggest that pregnant women with high oestradiol and/or immunosuppression will be vulnerable to HEV infection.

Abstract
Cd_{3}As_{2} is a three-dimensional topological Dirac semimetal with connected Fermi-arc surface states. It has been suggested that topological superconductivity can be achieved in the nontrivial surface states of topological materials by utilizing the superconductor proximity effect. Here we report observations of both π and 4π periodic supercurrents in aluminum-Cd_{3}As_{2}-aluminum Josephson junctions. The π period is manifested by both the magnetic-field dependence of the critical supercurrent and the appearance of half-integer Shapiro steps in the ac Josephson effect. Our macroscopic theory suggests that the π period arises from interference between the induced bulk superconductivity and the induced Fermi-arc surface superconductivity. The 4π period is manifested by the missing first Shapiro steps and is expected for topological superconductivity.

Abstract
BACKGROUND AND OBJECTIVES Nicotine, the main psychoactive component of tobacco, affects cell metabolism, proliferation, adhesion and, importantly, the osteogenic differentiation of fibroblasts. Approximately 15% of all orthodontic patients are adults among who one-fifth are smokers. Hence, it is necessary to have insight into the effects of nicotine on the osteogenic differentiation of hPDLCs during orthodontic tooth movement. This study aimed to investigate the effects and mechanisms of nicotine on the osteogenic differentiation of human periodontal ligament cells (hPDLCs) under the application of cyclic tensile stress. MATERIAL AND METHODS hPDLCs were obtained from donor third molars. The hPDLCs were treated with nicotine and/or cyclic tensile stress that was applied with a cell stress plus unit. The effect of nicotine on cell viability was analyzed using the MTT assay. The osteogenic differentiation of hPDLCs was detected by alkaline phosphatase staining, Alizarin Red S staining, quantitative real-time polymerase chain reaction and western blotting. RESULTS In combination with cyclic tensile stress, nicotine prevented the tensile stress-induced increase in alkaline phosphatase activity, formation of mineralization nodules and the upregulation of mRNA and protein expression of Runt-related transcription factor 2, transcription factor Sp7 and collagen type I; however, canonical Wnt pathway was activated. Furthermore, the addition of Dickkopf-related protein 1 and α-bungarotoxin counteracted the negative effect of nicotine and rescued the osteogenic differentiation of hPDLCs, respectively. CONCLUSION These results indicate that nicotine prevents the increased osteogenic potential of hPDLCs induced by cyclic tensile stress by binding to an α7 nicotinic acetylcholine receptor and activating the canonical Wnt pathway.

Abstract
Documented reports about T helper type 17 (Th17) cells have revealed that Th17 plays a critical role in inflammation and autoimmunity diseases. However, the role of Th17 in cancer remains contradictory. The interplay between Th17 and tumour cells in the tumour microenvironment of primary hepatic carcinoma (PHC) needs to be explored further and the relationship between Th17, regulatory T cells (Tregs ) and regulatory B cells (Bregs ) has not been defined completely. In this study, numerous experiments were undertaken to elucidate the interaction of Th17 and Treg /Breg cells involved in PHC. Our work demonstrated that an increased Th17 was detected in the peripheral circulation and in tumour tissues in PHC patients. In addition, increases in peripheral blood Th17 corresponded with tumour-node-metastasis (TNM) stage progression. Also, further studies indicated that Th17 cells were promoted by tumour cells in the PHC tumour microenvironment through both contact-dependent and -independent mechanisms, but cell-contact played the major important role in promoting the production and proliferation of Th17. When isolated CD4+ CD25+ CD127low Tregs and CD4+ CD25- CD127+ non-Tregs were cultured with autologous tumour cells, it implied that the phenotype of Th17 and Tregs was modified by tumour cells in the tumour microenvironment. As well as this, Th17 cells were also found to correlate positively with CD4+ forkhead box protein 3+ Tregs and CD19+ CD5+ CD1dhi Bregs in PHC. Notably, Th17 increased synchronically with Tregs and Bregs in PHC. These findings may provide new clues to reveal the mechanisms of immune escape in PHC.

Abstract
BACKGROUND Patients with port-wine stain (PWS) suffer physically and psychologically because of the high incidence (0.3%-0.5%) of the disease. Pulsed-dye laser (PDL) at 595 nm is the gold standard of the treatment for PWS. Nevertheless, clinicians intend to determine whether the dual-wavelength laser (DWL; 595-nm PDL + 1064-nm Nd:YAG) is an adequate choice in the treatment of non-treated PWS. This study is the first prospective within-patient controlled research seeking to investigate the safety and efficacy of DWL for the treatment of non-treated PWS. METHODS A total of 61 patients with non-treated flat facial PWS, who were treated using the Cynergy laser system in our clinic, were included in this study. Each PWS lesion was divided into two adjacent test treatment sites of similar size and colour. The two sites were randomly assigned to PDL or DWL treatment in a blinded manner of participants. In each case, two sets of treatment parameters were used: (i) 595-nm PDL and (ii) 595-nm PDL + 1064-nm Nd:YAG. Both had a 10 mm spot size, an epidermal cooling system and 1-s interpulse interval between two pulses. Clinical efficacy and safety outcomes were evaluated by visual assessment 2 months after treatment. RESULTS Comparison by visual evaluation suggests that the responses of non-treated PWS to treatment by PDL and DWL were not significantly different. Moreover, three patients developed scarring after DWL treatment. CONCLUSION Compared with PDL, DWL exhibits a higher risk of potential scarring and has no advantage in efficacy of treating non-treated PWS.

Abstract
Objective: To evaluate the population immunity to measles and explore the factors associated with measles susceptibility in Yunnan residents aged ≥20 years. Methods: 2 689 residents aged ≥20 years were selected by multistage stratified systematic randomized sampling in 252 villages of 42 counties in Yunnan Province between June and September in 2015. Each subject was surveyed by the same questionnaire, including general information, measles contained vaccine history, measles history, and 5 ml blood sample of each subject was collected. Serum IgG antibodies against measles virus were measured by ELISA. Positive was defined as the antibody concentration ≥250 mU/ml, and negative as <250 mU/ml. Non-conditional logistic regression model was used analyze the factors associated with measles susceptibility in adults. Results: Among 2 689 subjects, 1 214 were males (45.15%), and the overall positive rate of measles IgG antibody was 89.77%. Compared with subjects from the region where economic development was low, subjects from the region where economic development was moderate were likely to be susceptible to measles virus (OR=1.81, 95%CI: 1.33-2.47). Four age groups had higher risk of being susceptible to measles virus (compared with ≥40 years: 20-24 years old, OR=2.04, 95%CI: 1.26-3.31; 25-29 years old, OR=3.72, 95%CI: 2.37-5.86; 30-34 years old, OR=1.94, 95%CI: 1.22-3.09; 35-39 years old, OR=1.81, 95%CI: 1.07-3.05). Conclusion: Our results suggest that the serological susceptibility in adults (20-39 years), especially adults from the regions where the economic development was moderate, should be concerned. The additional vaccination strategy targeting young adults is important for reducing the risk of measles infection.

Abstract
OBJECTIVE Contrast enhanced ultrasound (CEUS) is an innovative technique that employs microbubble contrast agents to demonstrate parenchymal perfusion. Ultrasound contrast agent was reported to be directly used in human internal lumen to improve the observation capacity of ultrasound. However, CEUS has never been reported to be used in the guidance of percutaneous renal access in percutaneous nephrolithotomy (PCNL). This study aimed to assess the efficacy of CEUS-guided renal access in PCNL. METHODS In this retrospective study, percutaneous renal access was performed under real-time monitoring of CEUS during PCNL in a cohort of 20 patients with renal stones at Peking University First Hospital. Data regarding patients' demographic and clinical characteristics, therapeutic regimens, and postoperative information were collected from a comprehensive database containing comprehensive medical records of the patients undergoing PCNL. Briefly, the procedure was as follows. With the patient under general anesthesia, renal access was established by the guidance of CEUS. Afterwords, holmium laser, pneumatic or ultrasonic lithotripsy was used by the same urologist. The patient demographics, stone characteristics and procedure details were noted. Finally, appropriate statistical analyses were performed to evaluate the effectiveness and safety of the CEUS-guided percutaneous renal access in PCNL. RESULTS All the 20 patients underwent PCNL successfully with the help of CEUS guidance for tract creation. The collecting system was successfully accessed in all the patients, and only one patient underwent re-puncture. All the patients approached through a middle-pole percutaneous access. The median puncture time was 3.9 (2.9-4.6) min, and the median operating time was 112 (98.5-134.5) min. The preliminary stone-free rate of PCNL was 95.0% (19/20) as shown by the kidney, ureter, and bladder (KUB) radiographs 48 h postoperation, and the median decline in hemoglobin level was 10 (5.5-14.5) g/L. Two patients had transient postoperative fever and responded well to antibiotics. In addition, no other major complications were observed. CONCLUSION CEUS is a safe and effective alternative way of guidance for percuta-neous renal access for PCNL beginners. It makes this procedure more visualized and simpler, and produces clearer images than common ultrasonic ones. PCNL beginners might benefit from this method to shorten the learning curve of PCNL, while it warrants further comparative studies to clarify.

Abstract
OBJECTIVES Dyslipidaemia is common in perinatally HIV-infected (PHIV) youth receiving protease inhibitors (PIs). Few studies have evaluated longitudinal lipid changes in PHIV youth after switch to newer PIs. METHODS We compared longitudinal changes in fasting lipids [total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and TC:HDL-C ratio] in PHIV youth enrolled in the Pediatric HIV/AIDS Cohort Study (PHACS) Adolescent Master Protocol (AMP) study who switched to atazanavir/ritonavir (ATV/r)- or darunavir/ritonavir (DRV/r)-based antiretroviral therapy (ART) from an older PI-based ART and those remaining on an older PI. Generalized estimating equation models were fitted to assess the association of a switch to ATV/r- or DRV/r-based ART with the rate of change in lipids, adjusted for potential confounders. RESULTS From 2007 to 2014, 47 PHIV children/adolescents switched to ATV/r or DRV/r, while 120 remained on an older PI [primarily lopinavir/r (72%) and nelfinavir (24%)]. Baseline age ranged from 7 to 21 years. After adjustment for age, Tanner stage, race/ethnicity, and HIV RNA level, a switch to ATV/r or DRV/r was associated with a more rapid annual rate of decline in the ratio of TC:HDL-C. (β = -0.12; P = 0.039) than remaining on an older PI. On average, TC declined by 4.57 mg/dL/year (P = 0.057) more in the switch group. A switch to ATV/r or DRV/r was not associated with the rate of HDL-C, LDL-C, or TG change. CONCLUSIONS A switch to ATV/r or DRV/r may result in more rapid reduction in TC and the TC:HDL-C ratio in PHIV youth, potentially impacting long-term cardiovascular disease risk.

Abstract
UNLABELLED The achievement of more accurate diagnosis would greatly benefit the management of patients with osteogenesis imperfecta (OI). In this study, we present the largest OI sample in China as screened by next generation sequencing. In particular, we successfully identified 81 variants, which included 45 novel variants. We further did a genotype-phenotype analysis, which helps make a better understanding of OI. INTRODUCTION This study aims to reveal the gene mutation spectrum and the genotype-phenotype relationship among Chinese OI patients by next generation sequencing (NGS). METHODS We developed a NGS-based panel for targeted sequencing of all exons of 14 genes related to OI, and performed diagnostic gene sequencing for a cohort of 103 Chinese OI patients from 101 unrelated families. Mutations identified by NGS were further confirmed by Sanger sequencing and co-segregation analysis. RESULTS Of the 103 patients from 101 unrelated OI families, we identified 79 mutations, including 43 novel mutations (11 frameshift, 17 missense, 5 nonsense, 9 splice site, and 1 chromosome translocation) in 90 patients (87.4%). Mutations in genes encoding type I collagen, COL1A1 (n = 37), and COL1A2 (n = 29) accounts for 73.3% of all molecularly diagnosed patients, followed by IFITM5 (n = 9, 10%), SERPINF1 (n = 4, 4.4%), WNT1 (n = 4, 4.4%), FKBP10 (n = 3, 3.3%), TMEM38B (n = 3, 3.3%), and PLOD2 (n = 1, 1.1%). This corresponds to 75 autosomal dominant inherited (AD) OI patients and 15 autosomal recessive (AR) inherited patients. Compared with AD inherited OI patients, AR inherited patients had lower bone mineral density (BMD) at spine (P = 0.05) and less frequent blue sclera (P = 0.001). Patients with type I collagen qualitative defects had lower femoral neck BMD Z-score (P = 0.034) and were shorter compared with patients with type I collagen quantitative defects (P = 0.022). CONCLUSION We revealed the gene mutation spectrum in Chinese OI patients, and novel mutations identified here expanded the mutation catalog and genotype and phenotype relationships among OI patients.
