Abstract
Objective: To evaluate the impact of preemptive analgesia with ibuprofen on postoperative pain following the extraction of impacted mandibular third molars in a Chinese population, aiming to provide a clinical reference for its application. Methods: This multicenter, randomized, double-blind, placebo-controlled parallel-group trial was conducted from April 2022 to October 2023 at the Capital Medical University School of Stomatology (40 cases), Beijing TianTan Hospital, Capital Medical University (22 cases), and Beijing Chao-Yang Hospital, Capital Medical University (20 cases). It included 82 patients with impacted mandibular third molars, with 41 in the ibuprofen group and 41 in the control group. Participants in the ibuprofen group received 300 mg of sustained-release ibuprofen capsules orally 15 min before surgery, while the control group received a placebo. Both groups were instructed to take sustained-release ibuprofen capsules as planned for 3 days post-surgery. Pain intensity was measured using the numerical rating scale at 30 min, 4 h, 6 h, 8 h, 24 h, 48 h, and 72 h after surgery, and the use of additional analgesic medication was recorded during days 4 to 6 postoperatively. Results: All 82 patients completed the study according to the protocol. No adverse events such as nausea, vomiting, or allergies were reported in either group during the trial. The ibuprofen group exhibited significantly lower pain scores at 4 h [2.0 (1.0, 4.0) vs. 4.0 (3.0, 5.0)] (Z=-3.73, P<0.001), 6 h [2.0 (1.0, 4.0) vs. 5.0(2.5, 6.0)] (Z=-3.38, P<0.001), and 8 h [2.0 (1.0, 4.0) vs. 5.0 (2.0, 6.0)] (Z=-2.11, P=0.035) postoperatively compared to the control group. There were no statistically significant differences in pain scores between the groups at 30 min, 24 h, 48 h, and 72 h postoperatively (P>0.05). Additionally, 11 out of 41 patients (26.8%) in the ibuprofen group and 23 out of 41 patients (56.1%) in the control group required extra analgesic medication between days 4 and 6 post-surgery, with the ibuprofen group taking significantly fewer additional pills [0.0 (0.0, 1.0) vs. 1.0 (0.0, 3.0)] (Z=-2.81, P=0.005). Conclusions: A pain management regimen involving 300 mg of oral sustained-release ibuprofen capsules administered 15 minutes before surgery and continued for 3 d postoperatively effectively reduces pain levels and the total amount of analgesic medication used after the extraction of impacted mandibular third molars. Considering its efficacy, safety, and cost-effectiveness, ibuprofen is recommended as a first-line drug for perioperative pain management, enhancing patient comfort during diagnosis and treatment in a feasible manner.

Abstract
INTRODUCTION Mandibular asymmetry has negative impacts on maxillofacial aesthetics and psychological well-being. This study investigated the effects of unilateral injection of botulinum toxin type A (BTX-A) into the masseter muscle on mandibular symmetry. METHODS Forty Wistar rats (4-week-old) were divided into 4 groups (n = 10): control, group 1 (1U BTX-A), group 2 (3U BTX-A), and group 3 (1U BTX-A for 3 times). BTX-A was injected into the right masseter of treatment groups. Cone-beam computerized tomography scans were taken before the injection and then at 2 weeks, 4 weeks, and 6 weeks after injection. Histologic and immunohistochemical staining were done for the condylar cartilage. RNA sequencing and quantitative reverse transcription polymerase chain reaction were used to detect gene expression in the angular process. RESULTS In Groups 2 and 3, the right angular process length and the ramus height were reduced 4 weeks after injection, resulting in the mandibular midline deviating to the right side; the right condylar cartilage had reduced thickness and decreased expression of RUNX2, SOX9, and COL II (P <0.05). Two hundred sixty-one genes were differentially expressed (256 downregulated) in the angular process at 3 days post-BTX-A injection, and the calcium signaling pathway was unveiled through the Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis. Furthermore, TRPC1, Wnt5a, CaMKII, Ctnnb1, and RUNX2 expression were significantly downregulated at 1 and 3 days postinjection. CONCLUSIONS Unilateral injection of BTX-A into the masseter muscle in adolescent rats induces mandibular asymmetry by suppressing the angular process growth on the injected side.

Abstract
BACKGROUND Thoracoscopic lobectomy is accompanied by intense trauma and pain due to impaired chest wall integrity. We aimed to introduce a modified ultrasound-guided serratus anterior plane block (MUG-SAPB) for postoperative analgesia in patients who underwent thoracoscopic lobectomy, and to determine whether it could effectively alleviate postoperative pain and improve recovery quality. MATERIAL AND METHODS Overall, 78 patients randomly received either combined MUG-SAPB (0.25% ropivacaine, 10 mg dexamethasone, 40 mL) with patient-controlled intravenous analgesia (PCIA) or received PCIA alone. The primary outcomes were visual analog scale (VAS) scores at rest and during movement at 4, 8, 12, 20, 24, 48, and 72 h postoperatively. The secondary outcomes included use of opioids during surgery, numbers of rescue analgesics (butorphanol), frequency of patient-controlled analgesia (PCA), comfort score within 24 h postoperatively, and postoperative complications within 72 h. RESULTS Compared to the PCIA group, in the MUG-SAPB group, resting VAS scores at 4-24 h (P<0.05) and movement VAS scores at 4-12 h postoperatively (P<0.05) were lower; intraoperative use of sufentanil and frequency of PCA were less, and less rescue analgesia was used (P=0.02, P=0.04 and P=0.03, respectively). Patients in the MUG-SAPB group had faster first mobilization (P=0.04). The MUG-SAPB group had higher comfort scores than the PCIA group (P=0.03). None of the MUG-SAPB patients had any SAPB-related complications. CONCLUSIONS MUG-SAPB effectively relieved postoperative pain, reduced opioid consumption, and accelerated early ambulation in comparison with PCIA alone in patients who underwent thoracoscopic lobectomy.

Abstract
OBJECTIVE To compare the performance of machine learning models and traditional Cox regression model in predicting postoperative outcomes of patients with esophagogastric junction adenocarcinoma (AEG). METHODS This study was conducted among 203 AEG patients with complete clinical and follow-up data, who were treated in our hospital between September, 2015 and October, 2020. The clinicopathological data of the patients were processed for analysis using R language package and divided into training and validation datasets at the ratio of 3:1. The Cox proportional hazards regression model and 4 machine learning models were constructed for analyzing the datasets. ROC curves, calibration curves and clinical decision curves (DCA) were plotted. Internal validation of the machine learning models was performed to assess their predictive efficacy. The predictive performance of each model was evaluated by calculating the area under the curve (AUC), and the model fitting was assessed using the calibration curve. RESULTS For predicting 3-year survival based on the validation dataset, the AUC was 0.870 for Cox proportional hazard regression model, 0.901 for eXtreme Gradient Boosting (XGBoost), 0.791 for random forest, 0.832 for support vector machine, and 0.725 for multilayer perceptron; For predicting 5-year survival, the AUCs of these models were 0.915, 0.916, 0.758, 0.905, and 0.737, respectively. For internal validation, the AUCs of the 4 machine learning models decreased in the order of XGBoost (0.818), random forest (0.758), support vector machine (0.0.804), and multilayer perceptron (0.745). CONCLUSION The machine learning models show better predictive efficacy for survival outcomes of patients with AEG than Cox proportional hazard regression model, especially when proportional odds assumption or linear regression models are not applicable. XGBoost models have better performance than the other machine learning models, and the multi-layer perception model may have poor fitting results for a limited data volume.

Abstract
We determine the phase diagram of strongly correlated fermions in the crossover from Bose-Einstein condensates of molecules (BEC) to Cooper pairs of fermions (BCS) utilizing an artificial neural network. By applying advanced image recognition techniques to the momentum distribution of the fermions, a quantity which has been widely considered as featureless for providing information about the condensed state, we measure the critical temperature and show that it exhibits a maximum on the bosonic side of the crossover. Additionally, we backanalyze the trained neural network and demonstrate that it interprets physically relevant quantities.

Abstract
BACKGROUND Early detection of solid pancreatic masses through contrast-enhanced harmonic endoscopic ultrasound (CH-EUS) is important. But CH-EUS is difficult to learn. PURPOSE To design a deep learning-based contrast-enhanced harmonic endoscopic ultrasound diagnosis system (CH-EUS MASTER) for real-time capture and segmentation of solid pancreatic masses and to verify its value in the training of pancreatic mass identification under endoscopic ultrasound. METHODS We designed a real-time capture and segmentation model for solid pancreatic masses and then collected 4530 EUS images of pancreatic masses retrospectively, used for training and testing of this model at a ratio of 8:2. The model is loaded into the EUS host computer to establish the CH-EUS MASTER system. A crossover trial was then conducted to evaluate the model's value in EUS trainee training by successfully conducting two groups of EUS trainees in model learning and trainer-guided training. The intersection over union (IoU) and the time to find the lesion were used to evaluate the model performance metrics, and the Mann-Whitney test was used to compare the IoU and the time to find the lesion in different groups of subjects. Paired t-test was used to compare the effects before and after training. When α≤0.05, it is considered to have a significant statistical difference. RESULTS The model test showed that the model successfully captured and segmented the pancreatic solid mass region in 906 EUS images. The real-time capture and segmentation model had a Dice coefficient of 0.763, a recall rate of 0.941, a precision rate of 0.642, and an accuracy of 0.842 (when the threshold is set to 0.5), and the median IoU of all cases was 0.731. For the AI training effect, the average IoU of eight trainees improved from 0.80 to 0.87(95% CI, 0.032∼0.096; P = 0.002). The average time for identifying lesions in the pancreatic body and tail improved from 22.75 seconds to 17.98 seconds (95% CI, 3.664∼5.886; P < 0.01). The average time for identifying lesions in the pancreatic head and uncinate process improved from 34.21 seconds to 25.92 seconds (95% CI, 7.661∼8.913; P < 0.01). CONCLUSION CH-EUS MASTER can provide an effect equivalent to trainer guidance in training pancreatic solid mass identification and segmentation under EUS. This article is protected by copyright.

Abstract
BACKGROUND Except for public health case reports, the incidence of Zika virus (ZIKV), chikungunya virus (CHIKV), and dengue virus (DENV) infection are not available to assess the potential blood transfusion safety threat in Brazil. METHODS Pools of 6 donation samples (MP6) left over from human immunodeficiency virus, hepatitis B virus, and hepatitis C virus nucleic acid testing were combined to create MP18 pools (3 MP6 pools). Samples were tested using the Grifols triplex ZIKV, CHIKV, and DENV real-time transcription mediated amplification assay to estimate prevalence of RNAemia and incidence, and to compare these results to case reports in São Paulo, Belo Horizonte, Recife, and Rio de Janeiro, from April 2016 through June 2019. RESULTS ZIKV, CHIKV, and DENV RNAemia were found from donors who donated without overt symptoms of infection that would have led to deferral. The highest RNAemic donation prevalence was 1.2% (95% CI, .8%-1.9%) for DENV in Belo Horizonte in May 2019. Arbovirus infections varied by location and time of year, and were not always aligned with annual arbovirus outbreak seasons in different regions of the country. CONCLUSIONS Testing donations for arboviruses in Brazil can contribute to public health. Transfusion recipients were likely exposed to ZIKV, CHIKV, and DENV viremic blood components during the study period.

Abstract
The composite material based on N-, S-, and Fe-doped TiO2 (NSFe-TiO2) synthesized by wet impregnation was used as a photocatalyst to rapidly degrade sulfadiazine. The photocatalytic degradation behavior and mechanism of sulfadiazine on NSFe-TiO2 were investigated for revealing the role of degradation under ultraviolet light. The results showed that compared with TiO2, NSFe-TiO2 markedly improved the efficiency in photocatalytic degradation of sulfadiazine: more than 90% of sulfadiazine could be removed within 120 min by NSFe-TiO2 dosage of 20 mg L-1. The process conformed to first-order reaction kinetics model. The parameters such as loaded amount of NSFe-TiO2, solution pH value, humic acid concentration and recycle numbers on removal efficiency were also studied. Compared to neutral and alkaline conditions, acidic condition was not conducive to the photocatalysis. HA, Ca2+, Cu2+ and Zn2+ in the actual water body had mild inhibition on sulfadiazine degradation in UV/NSFe-TiO2 system. Fragments screened by high-resolution mass spectrometry were conducted to explore the oxidation mechanism and pathways of sulfadiazine degradation. On the whole, UV/NSFe-TiO2 photocatalysis has a good effect on sulfadiazine removal.

Abstract
BACKGROUND AND AIMS Distinguishing pancreatic cancer from nonneoplastic masses is critical and remains a clinical challenge. The study aims to construct a deep learning-based artificial intelligence system to facilitate pancreatic mass diagnosis, and to guide EUS-guided fine-needle aspiration (EUS-FNA) in real time. METHODS This is a prospective study. The CH-EUS MASTER system is composed of Model 1 (real-time capture and segmentation) and Model 2 (benign and malignant identification). It was developed using deep convolutional neural networks and Random Forest algorithm. Patients with pancreatic masses undergoing CH-EUS examinations followed by EUS-FNA were recruited. All patients underwent CH-EUS and were diagnosed both by endoscopists and CH-EUS MASTER. After diagnosis, they were randomly assigned to undergo EUS-FNA with or without CH-EUS MASTER guidance. RESULTS Compared with manual labeling by experts, the average overlap rate of Model 1 was 0.708. In the independent CH-EUS video testing set, Model 2 generated an accuracy of 88.9% in identifying malignant tumors. In clinical trial, the accuracy, sensitivity, and specificity for diagnosing pancreatic masses by CH-EUS MASTER were significantly better than that of endoscopists. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value were respectively 93.8%, 90.9%, 100%, 100%, and 83.3% by CH-EUS MASTER guided EUS-FNA, and were not significantly different compared to the control group. CH-EUS MASTER-guided EUS-FNA significantly improved the first-pass diagnostic yield. CONCLUSION CH-EUS MASTER is a promising artificial intelligence system diagnosing malignant and benign pancreatic masses and may guide FNA in real time. TRIAL REGISTRATION NUMBER NCT04607720.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is a sustainable technique that effectively treats morbid obesity. However, the molecular mechanisms underlying the improvement of metabolic health following this process warrants more investigation. This study investigates LSG-related molecules and uses bulk RNA-sequencing high-throughput analysis to unravel their regulatory mechanisms. METHODS Peripheral blood mononuclear cells (PBMC) were collected from ten obese patients with BMI ≥ 32.5 kg/m2 in the Department of General Surgery of Kunming First People's Hospital. After LSG, patients were followed up for one month, and blood samples were retaken. Blood samples from ten patients before and after LSG and bulk RNA-Seq data were analyzed in this study. LSG-associated gene expression was detected by weighted gene coexpression network analysis (WGCNA) and differential analysis. Subsequently, essential signature genes were identified using logistic least absolute shrinkage and selection operator (LASSO) and support vector machine-recursive feature elimination (SVM-RFE) algorithms. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and single-sample gene set enrichment analysis (ssGSEA) were utilized to reveal the potential functions of the target genes. Furthermore, the Pearson correlation of signature genes with leptin and lipocalin was also explored. Finally, we constructed a robust endogenous RNA (ceRNA) network based on miRWalk and starBase databases. RESULTS We identified 18 overlapping genes from 91 hub genes, and 165 differentially expressed mRNAs (DE-mRNA), which were revealed to be significantly associated with immune cells, immune response, inflammatory response, lipid storage, and localization upon functional enrichment analysis. Three signature genes, IRF1, NFKBIA, and YRDC, were identified from the 18 overlapping genes by LASSO and SVM-REF algorithms. The logistic regression model based on the three signature genes highlighted how robustly they discriminated between samples. ssGSEA indicated these genes to be involved in lipid metabolism and degradation pathways. Moreover, leptin levels were significantly reduced in patients undergoing LSG, and NFKBIA significantly negatively correlated with leptin. Finally, we identified how the long non-coding RNA (lncRNA) ATP2B1-AS1 regulated the expression of the signature genes by competitively binding to six microRNAs (miRNAs), which were hsa-miR-6509-5p, hsa-miR-330-5P, hsa-miR-154-5P, hsa-miR-145-5P, hsa-miR4726-5P and hsa-miR-134-5P. CONCLUSION This study identified three critical regulatory genes significantly differentiated between patients before and after LSG treatment and highlighted their potentially crucial role after bariatric surgery. This provides novel insights to increase our understanding of the underlying mechanisms of weight loss and associated metabolic improvement after bariatric surgery.

Abstract
Emerging evidence indicates that the alterations in the gut microbiota-brain axis (GBA), which is the bilateral connection between the gut microbial communities and brain function, are involved in several mental illnesses, including depression. Certain probiotic strains have been revealed to improve depressive behaviours and the dysregulation of 5-hydroxytryptamine (5-HT) metabolism in depression. Here we evaluated the potential antidepressant effects of Lactobacillus helveticus strains using an in vitro enterochromaffin cell model (RIN14B). The L. helveticus strain WHH1889 was shown to significantly promote the level of 5-hydroxytryptamine (5-HTP, 5-HT precursor) and the gene expression of tryptophan hydroxylase 1 (Tph1), which is the key synthetase in the 5-HT biosynthesis in RIN14B cells. Ingestion of 0.2 ml WHH1889 (1´109 cfu/ml) in a chronic unpredictable mild stress (CUMS) mouse model of depression for five weeks normalised depressive and anxiety-like behaviours in the forced swim test, tail suspension test, sucrose preference test, and open field test. Meanwhile, the CUMS-induced elevated level of serum corticosterone and declined levels of hippocampal 5-HT and 5-HTP were reversed by WHH1889. Furthermore, the disturbances of the gut microbiome composition with reduced microbial diversity were also improved by WHH1889, accompanied by the increased colonic 5-HTP level and Tph1 gene expression. In summary, these findings indicate that WHH1889 exerts antidepressant-like effects on CUMS mice, which is associated with the modulations of the 5-HT/5-HTP metabolism and gut microbiome composition. Therefore, ingestion of the L. helveticus strain WHH1889 with antidepressant potentials may become an encouraging therapeutic option in the treatment of depression.

Abstract
Since glass fiber-reinforced polymer (GFRP) bars have a lower modulus than steel bars, the design of GFRP-reinforced concrete (GFRP-RC) is often governed by the serviceability limit state (deflection and cracking) rather than the ultimate state. A new design method has been proposed in this paper for GFRP-RC beams based on the flexure crack width. The state when the maximum flexure crack width in the tensile zone reaches the limit of 0.5 mm specified by ACI 440.1R-15 was used as the design limit state. The concrete compressive strain at the extreme compression fiber of concrete under the design limit state was obtained by four-point bending tests of eight full-scale GFRP-RC beams and finite element analysis. Based on the concrete compressive strain under the design limit state and cross-sectional analysis, a design method for calculating the longitudinal reinforcement ratio of GFRP-RC beams under the design limit state is proposed. This design method is proven to be feasible by the experimental and the finite element results. In addition, the flexural capacity coefficient was discussed to investigate the safety reserve of the design method.

Abstract
With the large-scale construction of suburban railway viaducts, the noise problem along the viaducts is becoming more and more prominent. Conventional vertical noise barriers have been widely used to alleviate the noise problem along the suburban railway viaducts. However, conventional vertical noise barriers often have an adverse effect on the urban landscape and also block the view of train drivers and passengers. A type of near-rail low-height noise barrier was planned to install on the viaducts of Wenzhou Rail Transit Line S1 to reduce the impact of noise on residents along the railway lines. To assess the acoustic performance of the near-rail low-height noise barrier, a numerical procedure for railway viaduct comprehensive noise considering wheel-rail noise and structure-borne noise of the bridge and noise barriers was proposed and then verified by a field test. On this basis, numerical models were established to compare the acoustic performances of the near-rail low-height noise barrier and conventional vertical noise barrier. The influences of the height and top shape of the near-rail low-height noise barrier on the acoustic performance were discussed. Based on the numerical analysis results, it is found that both the near-rail low-height noise barrier and conventional vertical noise barrier have good acoustic performances. The noise reduction effect of the near-rail low-height noise barrier is slightly better than that of the conventional vertical noise barrier. The acoustic performance of the near-rail low-height noise barrier gradually improves, but the improvement rate gradually slows down as the height of the noise barrier increases. The noise reduction effects of both the inverted L-shaped and Y-shaped near-rail low-height noise barrier are obviously better than that of the vertical one, while the noise reduction effects of the inverted L-shaped near-rail low-height noise barrier are slightly better than the Y-shaped one.

Abstract
Objective: To compare the detection rate of advanced neoplasia and the number of people needing endoscopy in colorectal cancer screening giving at different starting age in population at high risk. Methods: Based on the screening project of early diagnosis and treatment of colorectal cancer in Jiashan county, Zhejiang province, two rounds of colorectal cancer screening were conducted between January 2007 and December 2020. After excluding participants who were not at high risk or had incomplete information, 27 130 participants and 31 205 participants were finally enrolled in round one and in round two, respectively. The spline analysis based on the generalized additive model was used to describe the trend of detection rate of advanced neoplasia with age. The detection rate and number of people needing endoscopy for the groups with starting age at 50, 45 and 40 years were calculated, and the differences in the detection rate were tested by χ2 goodness of fit test. Results: A total of 21 077 (77.69%) participants in round one and 25 249 (80.91%) participants in round two received endoscopy, in whom 1 097 (detection rate=52.05‰) and 1 151 (detection rate=45.59‰) had advanced neoplasia (cancers and advanced adenomas), respectively. The detection rate increased significantly with age, and the detection rate in round one were significantly higher than that in round two (P<0.05). The overall detection rates of advanced neoplasia for the groups with starting age at 50, 45 and 40 years were 61.11‰, 56.14‰ and 52.05‰ in round one, and 49.10‰, 46.75‰ and 45.59‰ in round two, respectively. The rates were significantly higher for the group with starting age at 50 years than that with starting age at 40 years in both round one and round two (P<0.05). The numbers of people needing endoscopy of advanced neoplasia for the groups with starting age at 50, 45 and 40 years were 17, 18, and 20 in round one, and 21, 22 and 22 in round two. Conclusions: The detection rate of advanced neoplasia increased with age. Starting screening at lower age might contribute to decreased detection rate and increased number of people needing endoscopy. However, the difference was limited.

Abstract
Glaucoma is the leading irreversible blinding eye disease worldwide, and China has the largest amount of primary angle-closure glaucoma (PACG). To reduce blindness, the therapeutic evolution can play a role. With the technical development of minimally invasive glaucoma surgery (MIGS), the treatment of angle-closure glaucoma has been in a transformation. This article reviews the literatures related to the advances of MIGS in the combined treatment of PACG. The research findings show that MIGS may become one of the preferred surgical treatments for PACG in the future clinical management of glaucoma.

Abstract
Myostatin (MSTN) is primarily expressed in skeletal muscle and plays an important role in the regulation of muscle growth and development as well as fat deposition; however, little is known about the molecular mechanism through which MSTN regulates body fat deposition. Therefore, in this study, we sought to identify the signaling pathways through which MSTN regulates fat accumulation in pigs. MSTN knockout (MSTN-/-) pigs showed increased muscle mass, decreased fat mass, and a leaner body composition. In this study, we found that the adipose tissue of MSTN-/- pigs exhibits the characteristics of beige adipose tissue, and the mRNA expression levels of beige adipose marker genes, including UCP3, Cidea, and CD137, were significantly increased. Remarkably, the observed beige phenotype was not adipocyte autonomous but rather caused by muscle-secreted myokine interleukin (IL)-6. This occurrence results in increased AMP-activated protein kinase (AMPK) phosphorylation in adipose tissue, which subsequently activates peroxisome proliferator-activated receptor gamma coactivator 1α and the conversion of white adipocytes to beige in pigs. Therefore, we concluded that MSTN deficiency leads to increased IL-6 secretion in skeletal muscle and activates AMPK in adipocytes, thereby increasing the beige adipose tissue in MSTN-/- pigs.

Abstract
Bombyx mori cypovirus (BmCPV) is an important pathogen of silkworm (B. mori), the economically beneficial insect. The mechanism of its interaction with host immune defence system in the process of infection is still not yet completely clear. Researches have demonstrated that virus-encoded microRNAs (miRNA) play a crucial role in regulating host-pathogen interaction, but few reports are available so far on miRNAs encoded by insect viruses, especially the RNA viruses. In this study, a putative miRNA encoded by the 10th segment of BmCPV genomic RNA, BmCPV-miR-10, was identified and functionally analysed. The expression of the putative BmCPV-miR-10 could be detected via stem-loop RT-PCR (reverse transcription-Polymerase Chain Reaction) in the midgut of silkworm larvae infected with BmCPV. BmCSDE1 (B. mori cold shock domain E1 protein) gene was predicted to be a candidate target gene for BmCPV-miR-10 with the miRNA binding site located in 3' untranslated region of its mRNA. The regulation effect of the putative BmCPV-miR-10 on BmCSDE1 was verified in HEK293 cells by lentiviral expression system, in BmN cells by transfecting BmCPV-miR-10 mimics. The qRT-PCR (quantitative real-time PCR) results showed that the putative BmCPV-miR-10 could suppress the expression of BmCSDE1. By injection of BmCPV-miR-10 mimics into the silkworm larvae infected with BmCPV, it was further proved that the putative BmCPV-miR-10 could suppress the expression of BmCSDE1 in vivo, then inhibit the expression of BmApaf-1 (B. mori apoptotic protease activating factor 1), while enhance the replication of BmCPV genomic RNAs to a certain extent. These results implied that the putative BmCPV-miR-10 could down-regulate the expression of BmCSDE1, then suppress the expression of BmApaf-1, thereby created a favourable intracellular environment for virus replication and proliferation.

Abstract
Cold atom experiments commonly use broad magnetic Feshbach resonances to manipulate the interaction between atoms. In order to induce quantum dynamics by a change in the interaction strength, rapid (∼μs) magnetic field changes over several tens of Gauss are required. Here, we present a compact design of a coil and its control circuit for a change in the magnetic field up to 36 G in 3 µs. The setup comprises two concentric solenoids with minimal space requirements, which can be readily added to existing apparatuses. This design makes the observation of non-equilibrium physics with broad Feshbach resonances accessible.

Abstract
Objective: To explore the predictive value of quantitative electroencephalogram (qEEG) in the poor outcome of children with non-traumatic disturbance of consciousness (DoC) in the pediatric intensive care unit (PICU). Methods: A prospective study was conducted. From January 2019 to May 2019, a total of 62 patients aged from 1 month to 11 years with non-traumatic DoC in the PICU of the First Affiliated Hospital of Bengbu Medical College were enrolled. Bedside monitoring with NicoletOne monitor was performed within 24 hours after admission, and qEEG parameters, including amplitude-integrated electroencephalogram (aEEG), relative alpha variability (RAV), relative band power (RBP), and spectral entropy (SE) were recorded. The state of consciousness was assessed with modified pediatric Glasgow coma scale (MPGCS) before monitoring. According to the pediatric cerebral performance category score at 1 year after discharge, the enrolled subjects were divided into good and poor outcome groups. The association between these variables and the poor outcome was analyzed by univariate and multivariate logistic regression analysis, and the predictive performance was analyzed by receiver operator characteristic (ROC) curve. Results: There were 39 males and 23 females, with the age of 12.0 (5.8, 24.0) months. Fifty patients (81%) were in the good outcome group and 12 patients (19%) in the poor outcome group. The univariate Logistic regression analysis showed that age (OR=1.037, 95%CI 1.001-1.074, P=0.041), severe abnormal aEEG (OR=128.000, 95%CI 10.274-1 594.656, P<0.01), RAV (OR=0.877, 95%CI 0.810-0.949, P=0.001), SE (OR=0.892, 95%CI 0.814-0.978, P=0.015), and MPGCS score (OR=0.511, 95%CI 0.349-0.747, P=0.001) were significantly associated with the poor outcome. However, the multivariate Logistic regression analysis showed that only severe abnormal aEEG (OR=315.692, 95%CI 6.091-16 362.298, P=0.004) and RAV (OR=0.808, 95%CI 0.664-0.983, P=0.033) were significantly associated with the poor outcome. The area under the curve (AUC) of the aEEG and RAV in predicting the poor outcome were 0.848 (95%CI 0.735-0.927, P<0.01) and 0.847 (95%CI 0.733-0.926, P<0.01), respectively. The optimal cut-off value was severe abnormal for the aEEG and 38% for the RAV, with sensitivity of 67% and 83%, specificity of 98% and 84%, positive predictive value of 89% and 55%, negative predictive value of 92% and 95%, and Youden index of 0.647 and 0.673, respectively. The AUC of the novel combined index of aEEG and RAV for predicting the poor outcome was 0.974 (95%CI 0.898-0.998, P<0.01). Conclusions: The aEEG and RAV are reliable predictors for the poor outcome of children with non-traumatic DoC, and the novel combined index of aEEG and RAV can improve the predictive performance. The qEEG can be used as a routine method for outcome assessment due to its good objectivity.

Abstract
INTRODUCTION Lingual thyroglossal duct cysts (LTGDC) are a rare kind of thyroglossal duct cyst. However, Sistrunk surgery is not very suitable for this type of cyst. This study aimed to explore the efficacy of transoral excision of LTGDC by plasma coblation. METHODS The present study reviewed 11 patients, comprising seven males and four females, who had been diagnosed with LTGDC preoperatively by computed tomography (CT) and fibre-optic electronic laryngoscopy. Of those patients, two had recurrence after surgery of epiglottic cysts. All these patients underwent transoral excision by plasma coblation. Then, we collected preoperative data of the patients, observed the effect of surgery, and analysed factors relevant to LTGDC, including the estimated bleeding amount, postoperative hospitalisation, complications and recurrence rates. RESULTS The connection between LTGDC and hyoid was tapered on sagittal images of CT, which was vital evidence for the diagnosis of LTGDC. Surgery was performed successfully for all 11 patients, and all recovered without complication. There was no evidence of recurrence after surgery, during follow up for 3-43 months. CONCLUSIONS Transoral surgery for LTGDC can be performed successfully by plasma coblation, which is an effective and safe surgical treatment. Fibre-optic electronic laryngoscopy and CT are essential to the diagnosis of LTGDC in order to avoid missing detection and misdiagnosis.

Abstract
Objective: To explore the association between lifestyle-related factors and colorectal adenoma. Methods: Based on the Screening Project of Early Diagnosis and Treatment of Colorectal Cancer in Jiashan county Zhejiang province, from August 2012 to March 2018, information gathered through records on questionnaire and colonoscopic diagnosis were collected from participants with positive results during the primary screening stage. According to the findings of colonoscopy, 11 232 controls without any colorectal diseases and 3 895 cases with colorectal adenoma were included in the study. Multivariate logistic regression models were used to analyze the association between lifestyle-related factors and colorectal adenoma. Results: After adjusting for possible confounding factors, results from multivariate logistic regression analysis showed that smoking, alcohol drinking and obesity were positively related to the risk of colorectal adenoma, with ORs (95%CIs) as 1.38 (1.24-1.54), 1.37 (1.24-1.51) and 1.38 (1.20-1.59) respectively. However, regular aspirin intake was negatively related with the risk of colorectal adenoma (OR=0.65, 95%CI: 0.53-0.80). After stratified by sex and age, data showed that the associations between smoking, alcohol drinking and colorectal adenoma were statistically significant in males, and the association between regular aspirin intake and colorectal adenoma was also statistically significant in older participants (aged 60 years and older). Conclusion: Smoking, alcohol drinking, regular aspirin intake and obesity were associated with colorectal adenoma.

Abstract
Objective: To analyze the clinical and genetic characteristics of primary hypoparathyroidism in children. Methods: The clinical data including age, symptoms, laboratory examination and cranial CT of 13 children with primary hypoparathyroidism diagnosed in the Capital Institute of Pediatrics from May 2017 to December 2019 were collected and analyzed retrospectively. These children and their parents also had gene detected by whole exome sequencing and (or) copy number variation sequencing. Results: Among the 13 patients, 7 were male and 6 female. The onset age was 3 years (1 day-12 years) old. The time from onset to confirmed diagnosis was 2 months (2 days-10 years). The clinical manifestations included convulsion (9 cases), tetany (2 cases), muscle pain (1 case), mental retardation (5 cases), deafness (1 case), and initially misdiagnosed epilepsy (5 cases). The lab examination showed average blood calcium level of (1.7±0.3) mmol/L, blood phosphorus of (2.8±0.4) mmol/L, and parathyroid hormone of 8.2 (3.9-28.7)ng/L. Head CT found 7 cases of ectopic calcification. Among the 7 cases who had genetic abnormalities according to the gene detection, 5 had heterozygous deletion of 22q11.2 region, and only one of whom was diagnosed with typical DiGeorge syndrome. As for the rest 2 cases, one had autosomal dominant hypocalcemia caused by novel heterozygous variation of CaSR gene c.2495T>G (p.F832C), and the other was hypoparathyroidism-deafness-renal dysplasia syndrome caused by GATA3 c.708dupC (p.S237Qfs*66) novel heterozygous variation. Conclusions: Primary hypoparathyroidism in children is mainly characterized by hypocalcemia and usually accompanied with diverse symptoms which may indicate genetic disorders. The detection of large fragment deletion should be considered to exclude 22q11.2 deletion syndrome.

Abstract
In this paper, a thermal convection-based optofluidic conveyor has been introduced, which can flexibly capture and manipulate multiple 20-120 μm silica particles with utmost accuracy. Near the end face, a fiber-based light source can confine 100 μm silica particles within 100 microns. By switching the light source of the fiber array, centimeter-range transportation of 100 μm SiO2 particles has been successfully achieved, which was not possible in optical trapping devices as we know. Through the comparative experiment with silica, polystyrene, and zirconium dioxide particles, the presented conveyor system is proved to be independent of the particles' dielectric properties. Moreover, sorting of silica and polystyrene particles based on the difference of mass densities has also been achieved. Additionally, the components of this conveyor (fiber array) and chip parts (microfluidic chamber) are freely detachable. Here, instead of expensive laser systems, a non-coherent light source has been utilized, which eventually eliminates the use of optical lens assemblies. All these features lead to making the equipment extremely simple in structure and low in cost. Besides, this optofluidic conveyor can be applied to transmit and sort various objects such as blood/cancer cells and microorganisms.

Abstract
OBJECTIVE Previous studies have shown that microRNA-765 (miR-765) is involved in certain biological behaviors of human cancers. However, abnormal expression and function of miR-765 have not been reported in osteosarcoma (OS). PATIENTS AND METHODS Changes in the expression of miR-765 and MTUS1 (Microtubule-associated tumor suppressor 1) were examined via Real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot analysis. The function of miR-765 was investigated through Cell Counting Kit-8 (CCK-8) and transwell assays in OS. The target of miR-765 was identified using a Dual-Luciferase reporter assay. RESULTS MiR-765 was upregulated in OS tissues. And upregulation of miR-765 promoted cell proliferation, migration and invasion in OS. In addition, MTUS1 was confirmed as a direct target gene of miR-765. Moreover, miR-765 promoted the progression of OS through targeting MTUS1. Furthermore, miR-765 was involved in tumorigenesis of OS through activating extracellular-signal-regulated kinase/ epithelial-mesenchymal transition (ERK/EMT) pathway. CONCLUSIONS MiR-765 targets MTUS1 to promote the progression of OS via mediating the ERK/EMT pathway. Therefore, miR-765 may be used as a novel biomarker for the diagnosis of OS.

Abstract
OBJECTIVE This study aims to elucidate the potential role of microRNA-448 in the recovery of spinal cord injury (SCI), and to explore the underlying mechanism. MATERIALS AND METHODS MicroRNA-448 expression was determined by microarray and the established SCI model in mice. The target gene of microRNA-448 was predicted using bioinformatics. The functional binding of the target gene to microRNA-448 was verified by Dual-Luciferase reporter gene assay. The regulatory effects of microRNA-448 and Bcl-2 on apoptosis, motor neuron number and grip strength were evaluated. After injection of microRNA-448 mimics, microRNA-448 inhibitor or Bcl-2 siRNA in mice, expression levels of PI3K/AKT and Caspase3 were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) and Western blot. RESULTS Grip strength of SCI mice significantly decreased compared with mice in the sham group. The microRNA-448 expression gradually increased with the progression of SCI, whereas the Bcl-2 expression decreased. Dual-Luciferase reporter gene assay showed the binding condition between microRNA-448 and Bcl-2. Furthermore, the Bcl-2 expression was negatively regulated by microRNA-448 at both mRNA and protein levels. The injection of microRNA-448 inhibitor into the injured spinal cord of SCI mice significantly upregulated the expressions of p-PI3K, p-AKT and Caspase3, as well as motor neuron regeneration and grip strength. However, the promotive effects of microRNA-448 inhibitor were blocked by Bcl-2 siRNA transfection. CONCLUSIONS MicroRNA-448 is upregulated after SCI, which may be involved in the regenerative process of spinal motor nerves by regulating PI3K/AKT/Bcl-2 axis.

Abstract
With the continuous development of production technology, the performance of glass-fiber-reinforced polymer (GFRP) bars is also changing, and some design codes are no longer applicable to new materials based on previous research results. In this study, a series of durability tests were carried out on a new generation of GFRP bars in laboratory-simulated seawater and a concrete environment under different temperatures and sustained loads. The durability performance of GFRP bars was investigated by analysing the residual tensile properties. The degradation mechanism of GFRP bars was also analysed by scanning electronic microscopy (SEM). Furthermore, the long-term performance of GFRP bars exposed to concrete pore solution under different stress levels was predicted using Arrhenius theory. The research results show that the degradation rate of GFRP bars was increased significantly at a 40% stress level. By comparing the test results, design limits, and other scholars' research results, it is demonstrated that the GFRP bars used in this test have a good durability performance. It is found that the main degradation mechanism of the GFRP bars is the debonding at the fiber-matrix interface. In the range test, the effects of a 20% stress level on the degradation of GFRP bars were not obvious. However, the long-term performance prediction results show that when the exposure time was long enough, the degradation processes were accelerated by a 20% stress level.

Abstract
Carbon steel is strong primarily because of carbides with the most well-known one being θ-Fe3C type cementite. However, the formation mechanism of cementite remains unclear. In this study, a new metastable carbide formation mechanism was proposed as ω-Fe3C → ω′-Fe3C → θ′-Fe3C based on the transmission electron microscopy (TEM) observation. Results shown that in quenched high-carbon binary alloys, hexagonal ω-Fe3C fine particles are distributed in the martensite twinning boundary alone, while two metastable carbides (ω′ and θ′) coexist in the quenched pearlite. These two carbides both possess orthorhombic crystal structure with different lattice parameters (aθ′ = aω′ = aω = \documentclass[12pt]{minimal}

Thus, the θ′ unit cell contains 12 Fe atoms and 4 C atoms, which in turn matches the composition and atomic number of the θ-Fe3C cementite unit cell. The proposed theory in combination with experimental results gives a new insight into the carbide formation mechanism in Fe-C martensite.

Abstract
Objective: To understand the characteristics and dynamics of individuals with HIV-1 subtype infection among injected drug users (HIV infection IDU) in Guangzhou between 2008 and 2015. Methods: HIV-1 RNAs were extracted from serum samples of the individuals that were newly diagnosed with HIV-1 infection among IDUs living in Guangzhou, between 2008 and 2015. The Pol gene segments of HIV-1 genome from these RNA samples were amplified by nested reverse transcription polymerase chain reaction (Nested-PCR) and sequenced. Subsequently, phylogenetic tree was reconstructed using both pol sequences of samples and references before the subtype of HIV-1 was determined. Distributions of HIV-1 subtypes detected in IDUs with different demographic characteristics in different years were compared. Results: A total of 437 pol gene segments were successfully obtained from 517 serum samples of HIV infection IDUs. The average age of 437 HIV infected IDUs was 37.37 years with standard deviation as 8.17 years. 51.5% (225/437) of the HIV infected IDU that registered residence were not in Guangdong. The Guangxi Registered residents were accounted for 54.2% (122/225). Proportion of subtype CRF07_BC (46.5%) appeared the highest, followed by CRF01_AE (24.3%), CRF08_BC (23.3%) and other subtypes (5.9%). The annual proportions of subtype CRF07_BC (trend χ(2)=19.703, P=0.006) and CRF08_BC (trend χ(2)=25.718, P=0.001) were significantly different. The proportion of subtype CRF07_BC decreased from 56.9% to 34.2% (trend χ(2)=15.139, P=0.000), while the proportion of CRF08_BC increased from 11.8% to 37.0% (trend χ(2)=22.577, P=0.000). The proportion of CRF08_BC was significantly higher in the HIV infected IDUs with Guangxi residence (Monte Carlo simulation of exact probability P=0.000, 99%CI: 0.000-0.000). Conclusions: CRF07_BC, CRF01_ AE and CRF08_BC were the predominant HIV-1 subtypes while multiple subtypes were co-circulated among the HIV infected IDUs in Guangzhou, between 2008 and 2015. Behavioral intervention set for HIV infected IDUs with Guangxi residence should be strengthened in Guangzhou.

Abstract
Objective: To explore the effect of listening to different types of music on intraocular pressure (IOP) and the underlying mechanism. Methods: Cross-sectional study. Participants were students from Sun Yat-sen University from October 2017 to May 2018. The study consisted of two parts. In part 1, three types of music, including relaxing, positive and negative music, were used to find out which kind of music could reduce IOP. IOP was measured before and after listening to music. A self-report questionnaire was used to evaluate emotional responses to each type of music. In part 2, the diurnal curve of IOP at 6 time points of 7:30, 9:30, 11:30, 13:30, 15:30 and 17:30 was measured to determine when the individual's IOP peaked. On the second day, the subject listened to the music that could reduce IOP for 15 minutes at his/her IOP peak time. IOP, blood pressure (BP) and heart rate (HR) were measured, and morphology of the chamber angle was captured by swept-source optical coherence tomography before and after listening to music. Image J software was used to measure the diameter and cross-sectional area of Schlemm's canal (SC). Paired t-test was used to compare BP, HR and SC measurements prior to and post-music intervention. Results: In part 1, fifteen subjects, including 7 males and 8 females, were enrolled, with an average age of (23±1) years. Relaxation music could significantly lower IOP [(11.62±2.51) vs. (12.65±2.49) mmHg (1 mmHg=0.133 kPa) , t=-2.39, P=0.032]. Positive music had no effect on IOP [(12.45±2.77) vs. (12.65±2.46) mmHg, P=0.566] and negative music increased IOP [(12.13±1.60) vs. (10.86±2.78) mmHg, t=2.45, P=0.029]. Relaxation music could also arouse relaxation emotions in 14 out of 15 subjects. In part 2, 55 subjects, including 20 males and 35 females, were enrolled, with an average age of (26±10) years. The diurnal curve of IOP at 6 time points of every participant was measured. At each individual's peak time point, listening to relaxation music could decrease IOP [(12.66±4.32) vs. (13.99±4.47) mmHg, t=-5.72, P<0.01]. HR before and after listening to relaxation music was (79.57±10.43) and (75.57±9.62) beats/min, respectively (t=-3.68, P=0.001). Systolic BP was (118.11±13.92) and (110.82±12.67) mmHg, respectively (t=-5.10, P<0.01). Diastolic BP significantly declined from (70.07±9.96) to (66.14±8.48) mmHg (t=-3.65, P=0.001). Average SC area significantly increased after listening to relaxation music [(255.96±93.36) vs. (230.07±92.20) pixels, t=2.88, P=0.006]. Average SC diameter was (8.62±1.89) and (9.41±2.37) pixels, respectively before and after listening to relaxation music (t=3.39, P=0.001). Conclusion: Relaxation music reduces IOP in healthy subjects probably by dilating the SC.(Chin J Ophthalmol, 2020, 56: 25-31).

Abstract
Objective: To understand the prevalence of drug resistance in treatment-naive HIV infected men who have sex with (MSM) in Guangzhou. Methods: HIV-1 RNA were extracted from the serum specimens of the MSM newly confirmed to be HIV-1 positive, living in Guangzhou and receiving no anti-viral therapy from 2008 to 2015. HIV-1 pol gene segments, including full protease and part reverse transcriptase, were amplified by nested reverse transcription polymerase chain reaction (nested-PCR) and sequenced by Sanger. Subsequently, the sequence data were submitted to Stanford University HIV Drug Resistance Database for drug resistance analysis. Results: Among 2 283 HIV infected MSM, HIV-1 pol gene segments were obtained from the serum samples of 1 986 HIV infected MSM aged 16-84 (30.18±8.24) years. Among them, the unmarried accounted for 74.17% (1 473/1 986), those of Han ethnic group accounted for 90.64% (1 800/1 986), those with education level of college or above accounted for 49.65% (986/1 986), those with education level of senior high school or secondary school accounted for 27.14% (539/1 986), those with education level of junior high school or below accounted for 20.89% (415/1 986). The distribution of subtypes was predominated by CRF07_BC (38.22%, 759/1 986) and CRF01_AE (34.49%, 685/1 986). The overall prevalence of drug resistance was 3.32% (66/1 986). The prevalence of resistance to protease inhibitors (PIs), nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs) were 1.36%(27/1 986), 0.65% (13/1 986) and 1.61% (32/1 986), respectively. Subtype B had higher resistance to PIs, NRTIs and NNRTIs and subtype CRF55_01B had highest resistance to NNRTIs compared with other subtypes. In subtype B, the resistant rates to D4T, EFV and NVP were highest (all 4.17%, 5/120), followed by those to NFV, AZT and RPV (all 3.33%, 4/120). In subtype CRF55_01B, the resistant rates to EFV and NVP were highest (all 5.50%, 16/291), followed by those to ETR and RPV (all 5.15%, 15/291). Conclusions: The prevalence of drug resistance in treatment-naive HIV infected MSM in Guangzhou remained at low level and current antiretroviral drugs are generally effective. However, subtype B and CRF55_01B have higher drug resistance.

Abstract
Glaucoma is a major cause of blindness and is frequently associated with elevated intraocular pressure. The trabecular meshwork (TM), the tissue that primarily regulates intraocular pressure, is known to have reduced cellularity in glaucoma. Thus, stem cells, if properly delivered to the TM, may offer a novel therapeutic option for intraocular pressure control in glaucoma patients. For this purpose, targeted delivery of stem cells to the TM is desired. Here, we used magnetic nanoparticles (Prussian blue nanocubes [PBNCs]) to label mesenchymal stem cells and to magnetically steer them to the TM following injection into the eye's anterior chamber. PBNC-labeled stem cells showed increased delivery to the TM vs. unlabeled cells after only 15-minute exposure to a magnetic field. Further, PBNC-labeled mesenchymal stem cells could be delivered to the entire circumference of the TM, which was not possible without magnetic steering. PBNCs did not affect mesenchymal stem cell viability or multipotency. We conclude that this labeling approach allows for targeted, relatively high-efficiency delivery of stem cells to the TM in clinically translatable time-scales, which are necessary steps towards regenerative medicine therapies for control of ocular hypertension in glaucoma patients.

Abstract
Zika virus (ZIKV) infection of pregnant women can cause fetal microcephaly and other neurologic defects. We describe the development of a non-human primate model to better understand fetal pathogenesis. To reliably induce fetal infection at defined times, four pregnant rhesus macaques are inoculated intravenously and intraamniotically with ZIKV at gestational day (GD) 41, 50, 64, or 90, corresponding to first and second trimester of gestation. The GD41-inoculated animal, experiencing fetal death 7 days later, has high virus levels in fetal and placental tissues, implicating ZIKV as cause of death. The other three fetuses are carried to near term and euthanized; while none display gross microcephaly, all show ZIKV RNA in many tissues, especially in the brain, which exhibits calcifications and reduced neural precursor cells. Given that this model consistently recapitulates neurologic defects of human congenital Zika syndrome, it is highly relevant to unravel determinants of fetal neuropathogenesis and to explore interventions.

Abstract
BACKGROUND Because of the potential severe clinical consequences of Zika virus (ZIKV) infection, the large numbers of asymptomatic travelers returning from ZIKV-active areas, the detection of ZIKV nucleic acid in blood, and reports of transmission of ZIKV through transfusion, in 2016 the Food and Drug Administration released recommendations for individual-unit nucleic acid testing to minimize the risk of transmission of ZIKV through blood transfusions. METHODS The American Red Cross implemented investigational screening of donated blood for ZIKV RNA by means of transcription-mediated amplification (TMA). Confirmatory testing of reactive donations involved repeat TMA, TMA testing in exploratory minipools, real-time reverse-transcriptase polymerase chain reaction, IgM serologic testing, and red-cell TMA. Viral loads in plasma and red cells were estimated by means of end-point TMA. The costs of interdicting a donation that was confirmed to be positive were calculated for the 15-month period between June 2016 and September 2017. RESULTS Of the 4,325,889 donations that were screened, 393,713 (9%) were initially tested in 24,611 minipools, and no reactive donations were found. Of the 3,932,176 donations that were subsequently tested individually, 160 were initially reactive and 9 were confirmed positive (a 1:480,654 confirmed-positive rate overall; positive predictive value, 5.6%; specificity, 99.997%). Six (67%) of the confirmed-positive donations were reactive on repeat TMA, of which 4 were IgM-negative; of these 4, all 3 that could be tested were reactive on minipool TMA. Two confirmed-positive donors had infections that had been transmitted locally (in Florida), 6 had traveled to ZIKV-active areas, and 1 had received an experimental ZIKV vaccine. ZIKV RNA levels in red cells ranged from 40 to 800,000 copies per milliliter and were detected up to 154 days after donation, as compared with 80 days of detection in plasma at levels of 12 to 20,000 copies per milliliter. On the basis of industry-reported costs of testing and the yield of the tests in our study, the cost of identifying 8 mosquito-borne ZIKV infections through individual-unit nucleic acid testing was $5.3 million per ZIKV RNA-positive donation. CONCLUSIONS Screening of U.S. blood donations for ZIKV by individual-donation TMA was costly and had a low yield. Among the 9 confirmed ZIKV-positive donations, only 4 were IgM-negative; of these donations, all 3 that were tested were reactive on minipool TMA.

Abstract
The temperature dependent single photon emission statistics of interface-fluctuation GaN quantum dots are reported. Quantum light emission is confirmed at temperatures up to ~77 K, by which point the background emission degrades the emission purity and results in a measured g(2) (0) in excess of 0.5. A discussion on the extent of the background contamination is also given through comparison to extensive data taken under various ambient and experimental conditions, revealing that the quantum dots themselves are emitting single photons with high purity.

Abstract
Objective: To investigate the clinical features and genetic characteristics of patients with ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) gene variants. Method: The clinical data of a patient with ENPP1 homozygous variants from Capital Institute of Pediatrics was collected, the related literature was searched from China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, National Center from Biotechnology Information and PubMed by using search term "ENPP1" , "hypophosphatemic rickets" . The literature retrieval was confined from 1980 to February 2017. The clinical manifestations, bone metabolism examinations, X-RAY and genotypes were reviewed. Result: Our patient was an 11 years old girl, with 7 years history of lower limb malformation. She showed significant valgus deformity of the knee (genu valgum). Metabolic examination revealed reduced level of plasma phosphate (0.86 mmol/L), a normal level of plasma calcium (2.30 mmol/L) and an elevated alkaline phosphatase level of 688 IU/L. The calcium-phosphorus product was 25.9. A homozygous nonsense variants of ENPP1 gene, c.783C>G (p.Tyr261X) in exon 7 was identified in the patient. Both parents were heterozygous carriers. Literature review identified 3 Chinese patients from one publication and 17 cases from twenty one publications around the world. None of the patients was found PHEX variants which is the most common variants among hypophosphatemic rickets patients. The disease onset age was 11 months to 10 years. Eight patients had short stature, five patients had the history of generalized arterial calcification of infancy. Four suffered from deafness, three showed localized calcifications of arteries, three patients manifested pseudoxanthoma elasticum and two suffered from ossification of posterior longitudinal ligament. Nine missense variants, six splicing variants and 4 nonsense variants were reported among these twenty patients. c.783C>G was found in two Chinese patients. Conclusion: ENPP1 gene mutation was a cause of patient with hypophosphatemic rickets. Comorbid features included generalized arterial calcification of infancy, early onset hearing loss, pseudoxanthoma and ossification of posterior longitudinal ligament. ENPP1 gene testing should be performed on hypophosphatemic rickets patients without PHEX gene variants. Long-term follow up is recommended. The most common types of ENPP1 gene variants were nonsense/splicing variants. The gene c.783C>G was the most common variants in Chinese patients.

Abstract
Objective: To understand the characteristic of subtype distribution among foreigners who were living with HIV-1, in Guangzhou. Methods: HIV-1 RNAs were extracted from 114 serum specimens in foreigners diagnosed with HIV-1 infections between 2008 and 2010, and in 2015. Partial pol gene of HIV-1 genome from these RNA samples were amplified by nested reverse transcription polymerase chain reaction (nested-PCR) with nucleotide sequenced. Subsequently, phylogenetic tree was reconstructed using the pol sequences of samples and references. Results: Among all the 114 samples, 57.9% were from males and 42.1% from females, with an average age as 35.21 years old and the standard deviation as 9.63 years. A total of 6.8% of the samples were from Africans. The top three subtypes were identified as CRF02_AG, subtype G and subtype C, accounted for 30.7%, 14.9% and 12.3% respectively. Compared with samples gathered from 2008 to 2010, the proportions of subtype A1 and CRF01_AE significantly increased, while the other subtypes significantly decreased in 2015 (χ(2)=37.570; P=0.013, 99% CI: 0.010-0.016). Proportions of CRF01_AE and subtype G among males outnumbered the females but the proportions of subtype A1, CRF02_AG and URF among females appeared the other way round (χ(2)=15.528; P=0.029, 99%CI: 0.024-0.033). Proportions of CRF02_AG and subtype G among HIV-1 positive Africans were larger than those from other Southeast Asian countries or areas, However, the proportion of CRF01_AE among HIV-1 positive patients from Southeast Asian countries was higher than those patients from other areas (χ(2)=39.399; P=0.009, 99% CI: 0.006-0.011). The rates of resistance to any drug of protease inhibitors (PIs), reverse transcriptase inhibitors (RTIs), as well as to PIs, NRTIs, and NNRTIs alone, were 21.9%, 12.3%, 6.1% and 7.0%, respectively. One of nine CRF01_AEs from the HIV-1 positive patients were found closely clustered in those phylogenetic tree (bootstrap=0.855) samples, collected from local patients in Guangzhou. Conclusions: Our findings showed that these foreign subtypes had been spread to the natives, more from the Africans than from the other areas, in Guangzhou. These types of viruses were different from the strains identified locally, suggesting that they might have been brought in by foreigners living with HIV-1, in Guangzhou. Programs related to care, support and behavioral intervention for HIV positive foreigners living in Guangzhou, should be strengthened.

Abstract
Objective: To introduce the development strategy of " Internet Plus" AIDS prevention services and its implementation results from 2010 to 2015 in Guangzhou, China. Methods: A gay men's health column was created for an active website aimed at men who have sex with men(MSM), in collaboration with local community organizations and the Guangzhou CDC. We designed intervention tools(including scenario-based applications and HIV risk self-assessment systems)and an online HIV testing service platform, integrated with applied psychology and behavioral theory as well as the " Internet Plus" concept, to intervene in HIV infection risk factors among MSM. Data of clients who accessed the " Internet Plus" AIDS services from 2010 to 2015 were used to evaluate service operation. Six-year consecutive surveys, conducted between April and July of each service year, were collected using a national AIDS sentinel surveillance questionnaire. For each year of surveillance, information on HIV prevalence, HIV interventions received during the past year, unprotected anal intercourse in the past 6 months, and HIV testing in the past year were compared using the chi-squared(χ2)test, to roughly reflect the effect of"Internet Plus" AIDS prevention services. Results: As of 31 December 2015, a total of 34 395 MSM had received " Internet Plus" services and HIV testing. The number of MSM tested increased from 2 338 in 2010 to 8 054 in 2015. From 2010 to 2015, newly identified HIV cases in each year were 59, 166, 312, 283, 291, and 270, which accounted for 25.0%, 32.8%, 38.8%, 35.1%, 30.5%, and 23.2% of MSM HIV cases of Guangzhou, respectively. Sentinel surveillance data showed that during the study period, 3 047 MSM were investigated, with 405, 400, 401, 633, 608, and 600 each year, respectively. The proportion of participants who had received any HIV intervention during the past year was 74.3%(301), 70.8%(283), 83.3%(334), 85.0%(538), 69.1%(420), and 83.8%(503)each year, respectively(trend χ2=6.53, P=0.011). HIV testing done during the past year accounted for 44.0%(178), 44.3%(177), 49.4%(198), 53.4%(338), 56.1%(341), and 60.2%(361)each year, respectively(trend χ2=40.83, P<0.001). Unprotected anal intercourse in the past 6 months accounted for 59.3%(240), 62.0%(248), 56.6%(227), 57.0%(361), 48.4%(294), and 43.7%(262)each year, respectively(trend χ2=42.21, P<0.001). Conclusion: The"Internet Plus"AIDS prevention services in this study represent a manner to enhance traditional HIV prevention strategies. We found these services to be effective in implementation of the national AIDS control and prevention strategy, especially for the expansion of intervention, testing, and case identification among high-risk populations.
