Abstract
Artificial intelligence (AI) is a potentially reliable assistant in the diagnosis of osteoporosis. This meta-analysis aims to assess the diagnostic accuracy of the AI-based systems using medical images. We searched PubMed and Web of Science from inception to June 15, 2020, for eligible articles that applied AI approaches to diagnosing osteoporosis using medical images. Quality and bias of the included studies were evaluated with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. The main outcome was the sensitivity and specificity of the performance of the AI-based systems. The data analysis utilized the R Foundation packages of "meta" for univariate analysis and Stata for bivariate analysis. Random effects model was utilized. Seven studies with 3186 patients were included in the meta-analysis. The overall risk of bias of the included studies was assessed as low. The pooled sensitivity was 0.96 (95% CI 0.93-1.00), and the pooled specificity was 0.95 (95% CI 0.91-0.99). However, high heterogeneity was found in this meta-analysis. The results supported that the AI-based systems had good accuracy in diagnosing osteoporosis. However, the high risk of bias in patient selection and high heterogeneity in the meta-analysis made the conclusion less convincing. The application of AI-based systems in osteoporosis diagnosis needs to be further confirmed by more prospective studies in multi-centers including more random samples from complete patient types.

Abstract
We report the development of a high-resolution spectrometer for extended x-ray absorption fine structure (EXAFS) studies of materials under extreme conditions. A curved crystal and detector in the spectrometer are replaceable such that a single body is employed to perform EXAFS measurements at different x-ray energy intervals of interest. Two configurations have been implemented using toroidal crystals with Ge 311 reflection set to provide EXAFS at the Cu K-edge (energy range 8.9-9.8 keV) and Ge 400 reflection set to provide EXAFS at the Ta L3-edge (9.8-10.7 keV). Key performance characteristics of the spectrometer were found to be consistent with design parameters. The data generated at the National Ignition Facility have shown an ≃3 eV spectral resolution for the Cu K-edge configuration and ≃6 eV for the Ta L3-edge configuration.

Abstract
Objective: To investigate the correlation between serum ferritin (SF) level and liver damage in the acute stage of dengue fever. Methods: A retrospective study was conducted to analyze 171 cases diagnosed with dengue fever as dengue fever group and 130 healthy patients as control group in Hangzhou 3A grade hospital from July to December 2017. Clinical data, SF and liver function related indicators were collected from both groups: alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) to analyze the correlation between liver damage and SF in patients with dengue fever. Results: ALT, AST, and SF levels were significantly higher in the dengue fever group than those in the healthy control group (Z = 11.553, 15.054 and 15.163, P < 0.001). SF levels were higher in the dengue fever combined with liver damage group than those without the liver damage group (z = 6.930, P < 0.001). However, there was no statistically significant differences in age, gender, peak body temperature, and history of liver disease (P > 0.05). In addition, Spearman's correlation analysis showed that SF was positively correlated with ALT, AST, and TBIL (r = 0.464, 0.531 and 0.315, P < 0.001). Among dengue patients with different SF levels, there were significant difference in ALT, AST levels and incidence of liver damage (H = 14.240 and 17.584, χ(2) = 49.547, P < 0.001). Patients with higher SF levels had higher ALT, AST levels and incidence of liver damage. Binary logistic regression analysis showed that hyperferritinemia (SF≥500 ng/ml) was the risk factor for dengue fever combined with liver damage (OR = 8.120, P < 0.001). Furthermore, ROC curve analysis showed that the AUC for SF to judge dengue fever combined liver damage was 0.846 (95% CI: 0.785-0.908), and the sensitivity and specificity when the SF cut-off value was 1 506 ng/ml were 74.8% and 83.3%. Conclusion: There is a certain correlation between the SF level and the degree of liver damage in acute stage of dengue fever patients, and hyperferritinemia is a risk factor for dengue fever combined with liver damage.

Abstract
Edge turbulence is important for plasma confinement, so the gas puffing imaging (GPI) diagnostic was proposed on the J-TEXT tokamak for the two-dimensional measurement of turbulence in the edge region. GPI is a diagnostic of plasma turbulence that uses a puff of neutral gas at the plasma edge to increase the local visible light emission for improved space-time resolution of plasma fluctuations. Considering the conditions of J-TEXT, the observation area is 21° away from the position of the optical system in the toroidal direction, and the observation area is 10 cm × 10 cm inside and outside the last closed flux surface. To have a lower divergence of the gas flow, the gas puff nozzle is specially designed. An interface has been developed for operation. To photograph the line radiation generated by the neutral gas cloud along the magnetic field lines, the optical system is designed. It is composed of a quartz glass, mirrors, commercial lenses, filters, and high-speed cameras. The high-speed camera can capture the line radiation with a speed up to 180 000 frames/s with 256 pixels × 256 pixels and an exposure time of 5 µs. In a recent experiment, the new GPI diagnostic has obtained some preliminary pictures.

Abstract
Graphene has taken impressive roles in light manipulation and optical engineering. The most attractive advantage of graphene is its tunable conductivity that could be dynamically modulated by various means. In this paper, we show that the spin Hall shift of light is dynamically tunable via changing the Fermi level of the graphene-wrapped spheres. Such tunability is prominent when different modes interfere with each other, such as at the interference of electric and magnetic dipolar modes or at the interference of electric dipolar and electric quadrupole modes. The circular polarization degree in the near field clearly demonstrates the strength of spin-orbit interaction, which is associated with spin Hall shift of light in the far-field. In addition, the spin Hall effect is shown in far-field detection plane and should be observed in experiment. Our results provide insights into how the spin Hall effect could be tuned and add new perspective in designing optical super-resolution imaging techniques.

Abstract
Objective: To investigate the correlation between cone-beam CT (CBCT) morphological stage of midpalatal suture (MPS) and cervical vertebral maturation stage (CS) of Chinese children and youth. Methods: This study was a retrospective observational study. A total of 1 076 CBCT images (male: 401, female: 675, age≥ 6.0 years old and<21.0 years old) taken from January 2013 to April 2018 in Peking University School and Hospital of Stomatology were included. MPS and CS of each sample were recorded according to previous studies. MPS included five stages: MPS 1, MPS 2, MPS 3, MPS 4s1 (substage), MPS 4s2 (substage), and MPS 5. CS included six stages: CS 1-6. Correlation between MPS and CS (ordinal categorical variables) was investigated by Spearman correlation coefficient and diagnostic test analysis. Results: Spearman coefficient between CS and MPS was 0.803. Diagnostic pairs with the best diagnostic performance include: CS 6-MPS 5, CS 5-MPS 4s2, CS 1-MPS 1, CS 4-MPS 4s1, CS 2-MPS 1, CS 3-MPS 3. The 90.9% (309/340) of individuals at CS 1-3 were at MPS 1-3 and 9.1% (31/340) were at MPS 4s1. The 33.0% (107/324) of individuals at CS 4 were at MPS 3 and 46.6% (151/324) were at MPS 4s1. Conclusions: CS has a close relationship with MPS. Individuals at CS 4 are recommended to take pre-treatment CBCT, so as to estimate feasibility of skeletal expansion with traditional tooth-borne rapid maxillary expansion.

Abstract
Candida albicans is one of the most common clinical pathogenic microorganisms and it is becoming a serious health threat, particularly to immunocompromised populations. Drug resistance of Candida species has also frequently emerged, and combination therapy for fungal infections has attracted considerable attention. In this study, we established the Qinling Mountains myxobacterial secondary metabolites library and a synergic assay in combination with ketoconazole against C. albicans was introduced for metabolites screening. Two active compounds with synergic anticandidal activities were obtained, which were identified as trans-resveratrol and cis-resveratrol. According to our study, resveratrol can reduce the dosage to 1/64 of ketoconazole as well as itraconazole. Furthermore, synergistic anticandidal activity of resveratrol combined with azoles was verified against a panel of clinical C. albicans isolates, and the combination strategy enhanced the azoles susceptibility of three fluconazole-resistant isolates. These findings suggest that resveratrol enhances the efficacy of azoles and provides a promising application in therapy of C. albicans infection.

Abstract
BACKGROUND Lung cancer is one of the most aggressive malignancies and the efficacy of chemotherapy or concurrent chemoradiation is limited in clinical application. Curcumin has been reported to block cancer development by modulating multiple signaling pathways. However, whether curcumin can inhibit gemcitabine-resistant non-small cell lung cancer through regulation of lncRNA and the involved molecular mechanisms are rarely reported. MATERIALS AND METHODS MTT assay, clonogenic assay, apoptosis assay, qRT-PCR, Western blotting, immunohistochemistry, xenograft experiment were carried out in the present study. RESULTS The results showed that curcumin suppressed gemcitabine-resistant non-small cell lung cancer cell proliferation and induced apoptosis. Curcumin upregulated the expression of lncRNA-MEG3 and PTEN, and MEG3 overexpression could increase the level of PTEN expression, while MEG3 knockdown decreased the level of PTEN expression in gemcitabine-resistant non-small cell lung cancer cells. Curcumin treatment failed to inhibit the proliferation and induce apoptosis in MEG3 knockdown or PTEN knockdown cells. CONCLUSIONS These findings show the antitumor activity of curcumin for potential clinical application in gemcitabine-resistant non-small cell lung cancer treatment.

Abstract
To assess the correlation between thyroid function and glucolipid metabolism in type 1 diabetic adults. A retrospective analysis was conducted in 230 type 1 diabetic adults who were hospitalized in the Department of Endocrinology of Shandong Provincial Hospital Affiliated to Shandong University from January 2008 to January 2020. It showed that thyroid stimulating hormone(TSH) was significantly positively correlated with total cholesterol (TC) (r=0.239), triglycerides (TG) (r=0.166) and low-density lipoprotein cholesterol (LDL-C) (r=0.249), respectively (all P<0.05). Free triiodothyronine (FT3) was significantly negatively correlated with fasting plasma glucose (FPG) (r=-0.272), glycated hemoglobin (HbA1c) (r=-0.240), TC (r=-0.197) and LDL-C (r=-0.220), respectively (all P<0.05). Free thyroxine (FT4) was negatively correlated with TC (r=-0.171) and LDL-C (r=-0.170), respectively (all P<0.05). TC was an independent predictor of TSH, FT3 and FT4, FT3 and FT4 were independent predictors of HbA1c. TSH was an independent predictor of TC, TG and LDL-C. Thyroid function is closely related to glucolipid metabolism in type 1 diabetic adults.

Abstract
BACKGROUND Evidence suggests that arteriosclerosis and sarcopenia (decreased muscle mass) share some of their many causes. However, after controlling for confounding factors, it is unclear whether the presence of arteriosclerosis correlates with sarcopenia. OBJECTIVES The aim of this paper is to explore whether sarcopenia is associated with arteriosclerosis. DESIGN A multicenter cross-sectional community-based study. MATERIALS AND METHODS A total of 2511 elderly subjects from six Chinese community health service centers in Anhui province were surveyed through an e-health promotion system to collect basic data and measurements of brachial-ankle pulse wave (baPWV), body composition, and handgrip strength (HGS). Pearson's correlation and binary logistic regression analyses were performed to identify associations between sarcopenia and high baPWV. RESULTS The prevalence rates of sarcopenia were 12.9% in men and 15.3% in women according to the 2019 standard of Asian Working Group for Sarcopenia. Among subjects with high baPWV, the proportion of sarcopenia was higher compared to those with normal baPWV (men: 17.7% vs. 3.7%; women: 20.4% vs. 4.9%, both p<0.001). Binary logistic regression analysis revealed that sarcopenia was associated with high baPWV (p<0.0001, odds ratio=1.619) after adjusting for confounding factors. HGS slightly and negatively correlated with baPWV (-0.19 in men and -0.18 in women). CONCLUSIONS The intertwined pathophysiological mechanisms shared by arteriosclerosis and sarcopenia are potential targets for future interventions to reduce morbimortality in subjects with both disorders. Upcoming prospective studies and clinical trials are expected to advance these findings.

Abstract
OBJECTIVE Intracerebral hemorrhage (ICH) is a devastating cerebrovascular disease of the central nervous system. In this study, we aimed to investigate plasma ZCCHC14 expression and its correlation with the diagnosis, prognosis, and clinical features of ICH. PATIENTS AND METHODS The plasma levels of ZCCHC14, TNF-α, IL-6, and IL-10 were dynamically detected among 130 ICH patients and 60 corresponding healthy subjects. A receiver operating characteristic (ROC) curve was used for the statistical analysis of the diagnostic and prognostic efficacy of ICH. RESULTS Hypertension (p = 0.005), ARB application (p = 0.014), ZCCHC14 level (p < 0.001), TNF-α (p < 0.001), IL-6 (p < 0.001), and IL-10 (p < 0.001) were found to be different between ICH patients and healthy controls. Multiple logistic regression analysis indicated that ZCCHC14 levels at admission were significantly different between the two groups (p = 0.002, OR = 0.440, 95% CI 0.290-0.718). Plasma ZCCHC14 levels dynamically changed, increasing at admission, and peaking on day 7. ZCCHC14 was a potential diagnostic marker for ICH (AUC = 0.953, p < 0.0001, 95% CI: 0.901-1.004) with a specificity and sensitivity of 84.6% and 95.5%, respectively. The plasma ZCCHC14 level was negatively correlated with IL-6 concentration (p = 0.024, r = -0.311) but was positively correlated with IL-10 concentration (p = 0.041, r = 0.298). Furthermore, the plasma ZCCHC14 level was correlated with hypertension (p = 0.005), GOS (p = 0.025), bleeding volume (p < 0.001), midline shift (p = 0.003), and poor outcome (p = 0.006). The low ZCCHC14 expression group had poorer outcomes (death or severe disability) than high ZCCHC14 expression group (Breslow, p < 0.001). CONCLUSIONS We found that the plasma ZCCHC14 level might be a potential biomarker for both the early diagnosis of and prediction of outcomes in ICH.

Abstract
BACKGROUND: Occupational exposure-related risk of Mycobacterium tuberculosis infection has been reported for village doctors in China. This prospective study aims to estimate the infection acquisition in this key population.METHODS: At baseline, all village doctors registered in Zhongmu County were tested by QuantiFERON®-TB Gold In-Tube (QFT) and QuantiFERON®-TB Gold Plus (QFT-Plus) in parallel. Those negatives for either of the tests were retested to identify conversions at the 2-year follow-up investigation.RESULTS: A total of 367 eligible participants completed the 2-year follow-up survey with frequency of conversion of 5.0% (18/361) for QFT and 6.1% (21/343) for QFT-Plus. The agreement of follow-up results between the tests was 93.2% with a κ coefficient of 0.43 (95%CI 0.20-0.65). Among QFT-Plus convertors, the difference between TB1 and TB2 tubes (TB2-TB1) was significantly increased as compared with baseline results (P = 0.039). Participants from the villages with occurrence of microbiologically confirmed pulmonary TB showed higher frequency of QFT conversions (11.0% vs. 3.2%, P = 0.011) and QFT-Plus conversions (12.3% vs. 4.4%, P = 0.027) than those from the villages without occurrence.CONCLUSION: Our results consistently suggest that capability on occupational protection and M. tuberculosis infection control should be improved in village doctors in China.

Abstract
Objective: To investigate the clinical characteristics of patients with coronavirus disease 2019 (COVID-19) with pharyngeal symptoms. Methods: From January 10 to May 15, 2020, clinical data of 1 228 patients with COVID-19 in Renmin Hospital of Wuhan University was collected (554 males and 674 females, with the range of age from 10 to 95 years old, the average age was 55.2 years old). The patients were divided into pharyngeal symptoms group (PS, 126 cases) and non-pharyngeal symptoms group (Non-PS, 1 102 cases) according to the presence or absence of pharyngeal symptoms such as pharyngalgia, pharyngeal dryness, pharyngeal itching, and pharyngeal foreign body sensation. The clinical data in terms of age, sex, medical history, duration of symptoms, treatment time, clinical classification, pulmonary imaging findings, whole blood cell count, serum hypersensitivity C-reactive protein, C-reactive protein, procalcitonin were statistically analyzed between the two groups. Chi-square, Fisher's exact test and Mann-Whitney U test were used for statistical analysis. Results: The most common pharyngeal symptoms were pharyngalgia (59.52%, 75/126), followed by foreign body sensation (23.02%, 29/126), pharyngeal dryness (8.73%, 11/126), and itching (8.73%, 11/126). The median age of the patients in the PS group was 51.50 years old, which was less than 57.50 years old in the non-PS group, showing a significant difference (P<0.05). The female cases accounted for 65.08% (82/126), which was higher than 53.72% (592/1 102) of the non-PS group (P<0.05). The incidence of bilateral lung inflammation confirmed by CT images was 73.81% (93/126), which was significantly lower than 83.48% (920/1 102) in the non-PS group (P<0.05). No significant differences were shown in the proportion of patients with clinical types, treatment days, duration of symptoms, white blood cell count, lymphocyte count, lymphocyte percentage, eosinophil count, eosinophil percentage, hypersensitive C-reactive protein, C-reactive protein, D-dimer, procalcitonin and other indicators (P>0.05). Conclusions: The incidence of pharyngeal symptoms in patients with COVID-19 is 10.26%. Most of these symptoms occur before or at the same time as the common symptoms of the disease. Therefore, patients with such symptoms may bring a greater risk of infection to otolaryngologist. According to the current clinical classification criteria, pharyngeal symptoms have no obvious correlation with the degree of the disease; but the presence of pharyngeal symptoms may suggest a milder clinical presentation and a better prognosis.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has resulted in millions of patients
infected worldwide and indirectly affecting even more individuals through disruption of
daily living. Long-term adverse outcomes have been reported with similar diseases from
other coronaviruses, namely Middle East Respiratory Syndrome (MERS) and Severe Acute
Respiratory Syndrome (SARS). Emerging evidence suggests that COVID-19 adversely affects
different systems in the human body. This review summarizes the current evidence on the
short-term adverse health outcomes and assesses the risk of potential long-term adverse
outcomes of COVID-19. Major adverse outcomes were found to affect different body systems:
immune system (including but not limited to Guillain-Barré syndrome and paediatric
inflammatory multisystem syndrome), respiratory system (lung fibrosis and pulmonary
thromboembolism), cardiovascular system (cardiomyopathy and coagulopathy), neurological
system (sensory dysfunction and stroke), as well as cutaneous and gastrointestinal
manifestations, impaired hepatic and renal function. Mental health in patients with
COVID-19 was also found to be adversely affected. The burden of caring for COVID-19
survivors is likely to be huge. Therefore, it is important for policy makers to develop
comprehensive strategies in providing resources and capacity in the healthcare system.
Future epidemiological studies are needed to further investigate the long-term impact on
COVID-19 survivors.

Abstract
Objective: To investigate the prevalence of Escherchia albertii in Shanxi province. Methods: The chicken intestines were enriched in EC broth. The eae gene was detected by PCR, and the eae-positive EC enrichments were inoculated in MacConkey agar plate. The eae-positive lactose non-fermenting isolates were presumed as Escherchia albertii, and then analyzed by triplex-PCR, 16S rDNA sequencing and MLST. Results: Two suspected Escherchia albertii were isolated from 250 samples of chicken intestines. It was identified as Escherchia albertii by phenotypic, specific genes,16S rDNA sequencing, and MLST analyses. The cytolethal distending toxin B (cdtB) showed positive by PCR,and they were clusted to Ⅱ/Ⅲ/Ⅴ group by sequencing. Conclusion: This study showed that the Escherchia albertii was existed in Shanxi province, China.

Abstract
Objective: To analysis the clinical characteristics and to summarize therapy experience of pediatric patients with cardiac syncope caused by anomalous origin of the left coronary artery from the right sinus (ALCA-R). Methods: We retrospectively analyzed the clinical data including clinical manifestations, myocardial injury biomarkers, radiological features, treatments and prognoses of pediatric patients with ALCA-R who were admitted to Beijing Children's Hospital from November 2015 to June 2018. Results: Four female patients were included in this analysis, age of onset was 7 to 14 years. All the patients presented with exercise-induced syncope and acute myocardial infarction. During the course, three patients presented with acute left heart failure, and one patient had history of sudden cardiac arrest. Laboratory data showed significant elevation of both the creatine kinase and troponin levels in four patients. All electrocardiogram (ECG) showed left main coronary artery occlusion, echocardiography suggested the possible anomalous origin of the left coronary artery in one child. Coronary CT angiography (CTA) revealed there was no coronary ostium in the left coronary sinus, and the left coronary artery had an anomalous origin from the right sinus. The left main coronary artery passed between the ascending artery and the root of the main pulmonary artery, which was compressed by these two large vessels. Two patients underwent cardiac magnetic resonance examination, which detected late gadolinium enhancement in ALCA-R with an interarterial course. Unroofing of the left coronary ostium (cut-back procedure) was performed in two patients, and the other two patients who were not operated were recommended to restrict their physical activities. During a regular follow-up period of 12-43 months, all the children survived without recurrent cardiovascular event. Conclusion: If an adolescent presents with exercise-induced syncope, acute myocardial infarction and even sudden death, and ECG shows left main coronary artery occlusion characteristics, we should consider the possibility of developmental abnormality of coronary artery, particularly the ALCA-R. Once diagnosed as ALCA-R, patients should be recommended to avoid strenuous activities,early recognition and surgical treatment are imperative for these patients.
