Abstract
Early and specific detection of cancer provides an opportunity for appropriate treatment. Although studies have suggested that QKI is a tumor suppressor gene, no studies have evaluated the diagnostic utility of QKI methylation in colorectal cancer (CRC). Here, we evaluated the methylation status of QKI by integrating the methylation data of tissues and cell lines of multiple cancer types. The diagnostic performance of QKI was analyzed in the discovery dataset from the TCGA CRC 450K array (n = 440) and tested in the test sets (n = 845) from the GEO. The methylation level of QKI was further validated in our independent dataset (n = 388) using targeted bisulfite sequencing. All detected CpG sites in the QKI promoter showed CRC-specific hypermethylation in 31 types of tumor tissues. In the discovery dataset, six consecutive CpG sites achieved high diagnostic performances, with AUCs ranging from 0.821 to 0.930. In the test set, a region (chr6: 163,834,452–163,834,924) including four consecutive CpG sites had robust diagnostic ability in distinguishing CRC and adenoma from normal samples. In the validation dataset, similar robust results were observed in both early- and advanced-stage CRC patients. In addition, QKI exhibited hypermethylation in the cfDNA of patients with CRC (n = 14). Collectively, the QKI promoter is a CRC-specific methylation biomarker and holds great promise for improving the diagnosis using minimally invasive biopsy.

Abstract
Colorectal cancer (CRC) remains one of the most common malignancies worldwide and its mechanism is unclear. Polymeric immunoglobulin receptor (PIGR) which plays an important role in mucosal immunity is widely expressed in the mucosal epithelium and is dysregulated in different tumors. However, the role and underlying mechanisms of PIGR in CRC remain unclear. Here, we demonstrated that PIGR was hypermethylated and downregulated in our cohort (N = 272), and these features were associated with reduced overall survival in patients (HRmethylation 1.61, 95% CI [1.11-2.33]). These findings were validated by external TCGA and GEO data. Moreover, PIGR overexpression inhibits CRC cell malignant phenotypes in vitro and impedes CRC cells growth in male BALB/c nude mice. Mechanistically, PIGR physically associates with RE1 silencing transcription factor (REST) and blocks the transcription of laminin subunit beta 3 (LAMB3). Subsequently, the AKT-FOXO3/4 axis was suppressed by downregulated LAMB3. In the drug sensitive assay, PIGR-overexpressing cells were more sensitive to cisplatin and gemcitabine. Together, PIGR may serve as a powerful prognostic biomarker and putative tumor suppressor by suppressing the AKT-FOXO3/4 axis by downregulating LAMB3 in CRC. Our study may offer a novel therapeutic strategy for treating CRC patients who highly express PIGR with cisplatin and gemcitabine.

Abstract
Objective: To evaluate the occurrence and recovery of adverse drug reactions (ADRs) of preventive treatment in the elderly population with latent tuberculosis infection (LTBI). Methods: A total of 2 583 elderly patients with LTBI were recruited in Zhongmu, Henan Province from July 1 to October 17, 2015. Face-to-face surveys and physical examinations were used to obtain the basic information of the participants, and the body mass index (BMI) was calculated. Fasting venous blood was collected from the participants for blood biochemical and routine blood tests. The random numbers were generated by Excel 2010, and the participants were divided into group A (1 284 cases) and group B (1 299 cases) by simple randomization. Both group A and group B received combination treatment of isoniazid and rifapentine. Group A was treated for 8 weeks with weekly doses of isoniazid at 15 mg/kg and 900 mg for those with body weight ≤50 and>50 kg, respectively, and the doses of rifapentin were 750 and 900 mg, respectively. Group B was treated twice a week for 6 weeks, the doses of isoniazid in patients with body weight ≤50 and>50 kg were [600-(50-body weight)×15] (rounded up) and 600 mg, respectively, and the doses of rifapentin were 600 and 450 mg, respectively. During the treatment period, doctors observed, inquired about and recorded symptoms related to ADRs, and blood biochemical and routine blood tests were performed at 4 weeks after taking the drug, the end of the treatment, and 3 months after the end of the treatment. The patients with ADRs were treated accordingly by severity. The ADRs and graded treatment outcomes of LTBI patients in group A and group B were compared. Results: The age[M(Q1,Q3)]of the participants was 60 (55,65) years old, and 54.7% (1 412/2 583) were males. There were no statistical differences in age, gender, BMI and baseline biochemical indexes between groups A and B (all P values>0.05). The incidence of ADRs in group A and group B were 18.5% (237/1 279) and 16.3% (209/1 279), respectively, and those with alanine aminotransferase (ALT)≥5 ULN accounted for 0.8% (7/931) and 1.1% (11/987), aspartate aminotransferase (AST)≥5 ULN accounted for 0.3% (3/931) and 0.3% (3/987), respectively, and there were no statistically significant differences (all P values>0.05). There were 7 and 11 patients with ALT≥5 ULN in group A and group B, respectively, and 3 patients with AST≥5 ULN for each group, respectively. After treatment, except for 2 patients with ALT≥5 ULN in group B, ALT and AST levels in all the other patients returned to normal. There were 15 and 10 patients with abnormal white blood cell count in group A and group B, respectively, and 10 and 9 patients returned to normal after treatment. Conclusion: LTBI preventive treatment has a high incidence of adverse drug reactions, but it can be effectively controlled through active monitoring and graded management.

Abstract
OBJECTIVE Identification of reliable biomarkers for the diagnosis and prognosis of gastric cancer (GC) is very important for achieving early cancer detection and improving clinical outcomes. The aim of the present study was to explore the clinical significance of serum exosomal miR-134 in GC. METHODS A total of 133 GC cases were enrolled in this study, and quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) was carried out to measure the relative serum exosomal miR-134 expression level. The association between serum exosomal miR-134 expression and clinicopathological characteristics was investigated. RESULTS Our results showed that serum exosomal miR-134 expression was significantly lower in GC patients than in controls. In addition, serum exosomal miR-134 discriminated GC cases from healthy controls with high accuracy. Moreover, reduced serum exosomal miR-134 expression was closely associated with aggressive clinical variables including TNM stage, lymph node metastasis and invasion depth. Furthermore, Kaplan-Meier analysis revealed that GC patients with low serum exosomal miR-134 expression tended to have shorter overall survival and relapse free survival. In multivariate analysis, serum exosomal miR-134 was an independent prognostic marker for GC. CONCLUSION In conclusion, serum exosomal miR-134 might serve as a promising diagnostic and prognostic biomarker for GC.

Abstract
Objective: The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China. Methods: This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems. Results: According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%). Conclusion: Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Abstract
BackgroundDeucravacitinib (DEUC) is a novel, oral, selective TYK2 inhibitor with a unique allosteric mechanism of action that has demonstrated efficacy in patients with psoriasis (PsO)1 and psoriatic arthritis (PsA).2 TYK2 mediates signalling of select immune cytokines, eg, interleukin (IL) 23, IL-12, and Type I interferons, whereas the related Janus kinases (JAK) 1/2/3 mediate signalling of a wider array of cytokines and mediators involved in inflammatory, developmental, metabolic, and hematopoietic pathways. DEUC reduced inflammatory markers associated with skin and joint manifestations but did not result in laboratory abnormalities associated with inhibition of JAK1/2/3 in a PsA trial.3ObjectivesTo identify baseline biomarkers that predict response to DEUC in patients with PsA.MethodsThe double-blind Phase 2 trial (NCT03881059) enrolled 203 patients with PsA randomised 1:1:1 to placebo (PBO), DEUC 6 mg once daily (QD), or 12 mg QD.2 Molecular profiling of baseline serum samples was performed by immunoassays. Clinical response at Week 16 was measured by ≥20% improvement from baseline in American College of Rheumatology Improvement Criteria (ACR 20) and ≥75% improvement from baseline in Psoriasis Area and Severity Index (PASI 75) scores.ResultsBiomarkers of the IL-23/T helper cell type 17 pathway, including IL-17A, IL-17‒induced β-defensin 2 (BD2), and IL-19, were associated with higher PASI but not Psoriatic Arthritis Disease Activity Scores overall at baseline. PASI 75 responders in DEUC-treated groups had higher baseline levels of IL-17A compared with nonresponders. In contrast, PASI 75 responders in PBO-treated patients had lower baseline expression of IL-17A, BD2, and IL-19 compared with nonresponders. In patients treated with DEUC 12 mg QD, greater reductions in BD2 were observed in the PASI 75 responder group compared with nonresponder group. When patients were dichotomised by median baseline biomarker level, higher clinical responses in both PASI 75 and ACR 20 were achieved in those with higher baseline overall biomarker levels in the DEUC-treated groups compared with the PBO group. Higher baseline expression of IL-23 biomarkers IL-17A, IL-19, and BD2 enriched ACR 20 response in patients treated with DEUC compared with PBO (OR=5.64, 6.68, and 4.99, respectively). While greater benefit was observed in high-biomarker groups, the low-biomarker populations still manifested clinical responses although not significant (Figure 1).ConclusionPatients who had higher expression of IL-23 pathway biomarkers were more likely to benefit from DEUC compared with placebo in skin and joint manifestations of PsA. These results reinforce the value of TYK2 inhibition in patients with IL-23‒mediated diseases. The potential value of IL-23-pathway markers in predicting higher responses to DEUC should be further explored in larger trials.References[1]Armstrong A et al.

Abstract
We reported a case of vascular Ehlers-Danlos syndrome presenting with recurrent pulmonary hemorrhage. A 22-year-old man was admitted for intermittent hemoptysis and chest pain during the past 18 months. Computed tomography of chest showed bilateral nodules and cavities with halo sign. Inflammatory markers, including erythrocyte sedimentation rate, C reactive protein and interleukin 6, were within normal range. The microbiological and pathological examination of bronchoalveolar lavage fluid and CT-guided percutaneous lung biopsy failed to draw a diagnosis. The pulmonary lesions waxed and waned despite empirical antibacterial, antifungal, antimycobacterial, and anti-parasite treatment. Video-assisted thoracoscopic lung biopsy showed pulmonary hemorrhage, hematoma, ossification, and fibrous nodules, suggesting vascular Ehlers-Danlos syndrome. The molecular testing revealed a heterozygous missense variant in the COL3A1 gene which confirmed the diagnosis of vascular Ehlers-Danlos syndrome. The patient had no skin hyperextensibility or joint hypermobility. During 3-year follow-up, there were no evidence of other vascular or organ involvement except he had intermittent minor hemoptysis. Through this clinical pathological discussion, we aimed to remind pulmonologist to consider the possible diagnosis of vascular Ehlers-Danlos syndrome in young patients with recurrent hemoptysis and waxing and waning pulmonary nodules, cavities, or cysts on CT scan who has neither obvious systematic inflammation nor effective reaction on empirical antimicrobial therapy. Molecular testing should be carried out as soon as possible in a suspected patient to avoid unnecessary invasive examinations.

Abstract
A 52-year old man was admitted to our hospital because of dyspnea on exertion for 2 months and subcutaneous nodules for 1 month. Chest enhanced CT showed bilateral hilar and mediastinal lymphadenopathy. Bronchial alveolar lavage fluid revealed a CD4+/CD8+ T cell subsets ratio of 4.3 and culture for acid-fast bacillus (AFB) was negative. The pathology of skin nodules and transbronchial needle aspiration biopsy guided by endoscopic ultrasound (EBUS-TBNA) revealed non-caseating necrotizing epithelioid granulomas with negative acid-fast bacilli staining and periodic acid-Schiff staining, which was compatible with sarcoidosis. The patient was diagnosed as sarcoidosis and glucocorticoid was administrated. The subcutaneous nodules were improved. However, the lymph nodes were enlarged instead of shrinking after 6-month therapy. The failure to respond to glucocorticoids raised the possibility of sarcoidosis complicated with tuberculosis infection. The patient received anti-tuberculosis therapy. Lymphadenopathy responded within 4 months, and there was complete regression after 18-month treatment. The patient was followed up for 5 years and repeated chest CT scan showed that the sizes of bilateral hilar and mediastinal lymph nodes were normal.

Abstract
Objective: To analyze the efficacy of sinonasal adenoid cystic carcinoma (ACC) with perineural invasion (PNI), and explore the prognostic value of PNI on sinonasal adenoid cystic carcinoma. Methods: The clinical data of 105 patients with sinonasal ACC admitted to Cancer Hospital, Chinese Academy of Medical Sciences from January 2000 to December 2016 were retrospectively reviewed. All patients were restaged according to American Joint Committee on Cancer 8th edition. Follow-up visits were conducted to obtain information of treatment failure and survival outcome. The Log rank test was used for univariate analysis of prognostic factors, and Cox regression model was used for multivariate prognostic analysis. Results: The maxillary sinus (n=59) was the most common primary site, followed by the nasal cavity (n=38). There were 93 patients with stage Ⅲ-Ⅳ. The treatment modalities included surgery alone (n=14), radiotherapy alone (n=13), preoperative radiotherapy plus surgery (n=10), and surgery plus postoperative radiotherapy (n=68). The median follow-up time was 91.8 months, the 5-year local control (LC), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) rates were 72.6%, 73.0%, 52.9% and 78.0%, respectively. There were 33 patients (31.4%) with PNI-positive. The 5-year DMFS, PFS, and OS rates of PNI-positive group were 53.7%, 29.4% and 56.5%, respectively, which were significantly inferior to those of PNI-negative group (80.8%, 63.0% and 86.8%, respectively, P<0.05), while there was no significant difference in the 5-year LC rate between both groups (64.5% vs 76.5%, P=0.273). The multivariate Cox regression analysis showed PNI was one of the poor prognostic factors of DMFS (HR=3.514, 95%CI: 1.557-7.932), PFS (HR=2.562, 95%CI: 1.349-4.866) and OS (HR=2.605, 95%CI: 1.169-5.806). Among patients with PNI-positive, the 5-year LC, PFS and OS rates of patients received surgery combined with radiotherapy were 84.9%, 41.3% and 72.7%, respectively, which were significantly higher than 23.3%, 10.0% and 26.7% of patients receiving surgery or radiotherapy alone (P<0.05). Conclusion: The presence of PNI increases the risk of distant metastasis in patients with sinonasal ACC. Compared with patients with PNI-negative, the prognosis of patients with PNI-positive is relatively poor, and surgery combined with radiotherapy for PNI-positive sinonasal ACC results in good clinical outcomes.

Abstract
Alkylphosphinates have received extensive attention in the past few decades because of their very useful mechanical properties, electrical properties, low density, and low toxicity, and have been widely used in flame-retardant materials and other fields. In this work, aluminum diethylphosphinate is successfully synthesized under atmospheric pressure. More importantly, two novel dialkylphosphinates, aluminum dioctylphosphinate and aluminum didecylphosphinate, are first synthesized and characterized. The structures of these aluminum dialkylphosphinates are confirmed by nuclear magnetic resonance, Fourier-transform infrared spectroscopy, and high-resolution mass spectrometry, and the microscopic morphology and thermal stability are analyzed by scanning electron microscopy and thermogravimetric analysis, respectively. Furthermore, conditions for the synthesis of aluminum dioctylphosphinate are optimized. Compared with the traditional method of synthesizing dialkylphosphinates under high pressure, the method reported in this paper has the advantages of high safety, easy operation, and low economic cost, which makes it suitable for industrial production.

Abstract
Objective: To examine the safety and feasibility of gasless submental-transoral combined appoach endoscopic thyroidectomy for papillary thyroid carcinoma (PTC). Methods: A retrospective analysis of the clinical data of 41 patients with PTC who underwent the gasless submental-transoral combined appoach endoscopic thyroidectomy at the Department of Head and Neck Surgery, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from November 2020 to April 2021. There were 5 males and 36 females with the age of (35.0±8.7) years (range: 19 to 58 years). A horizontal incision with a length of 2.0 cm is made under the chin as an observation hole, a 10 mm Trocar and a self-developed retractor are inserted, and two 5 mm longitudinal incisions are made on the labial side in the vestibule of the oral cavity as an operation hole, each inserting a 5 mm Trocar, the operation direction is from the cranial side to the caudal side. The sensation of the lower lip and chin was measured on the first day and one month postoperative. The operation time, hospital stay, the number of lymph nodes dissected and postoperative complications were recorded. Results: Surgical procedures in all cases were successfully completed under endoscopic approach without transfering to open surgery. The operation time was (99±34) minutes (range: 50 to 180 minutes) and the postoperative hospital stay was (3.4±2.2) days (range: 2 to 16 days). The maximum diameter of PTC was (7.6±5.8) mm (range: 2 to 30 mm), and the number of lymph nodes of the central compartment dissection was 6(5) (M(IQR)) (range: 1 to 25). The duration of follow-up is 1 month after operation, and the follow-up method is adopted in outpatient clinic. Postoperation complications included 2 cases of transient hypoparathyroidism, One case of recurrent laryngeal nerve injury (continue to follow up to assess whether it is a temporary injury). Postoperative minor chyle leak, seroma, and local redness and swelling in 1 case each were cured after conservative treatment. 1 case of transient minor numbness of the lower lip was observed. No permanent hypoparathyroidism, postoperative bleeding and numbness of the chin was observed.

Abstract
Covalently closed circular DNA (cccDNA) of hepatitis B virus (HBV) is the template for HBV replication. Currently, there is a lack of therapeutic drugs that directly target cccDNA. Therefore, blocking cccDNA supplements as fast as possible and reducing the existing cccDNA is the key to achieving a complete cure of chronic hepatitis B. Previous studies have suggested that cccDNA had a long half-life, but a recent study showed that it only took a few months to update cycle of cccDNA pool, and its number was much less than previously predicted. In the future, with the advent of new antiviral drugs that can completely inhibit HBV replication, it is expected that the cccDNA pool will be completely cleared due to its supplement complete blockade, so as to achieve virological cure of chronic hepatitis B.

Abstract
BACKGROUND Despite reports on neuroprotective effects of dietary theobromine intake, whether dietary theobromine has beneficial effects on cognitive function is unclear. OBJECTIVES To investigate the association between dietary theobromine and cognitive function. DESIGN A cross-sectional study. SETTING Data were collected from the 2011-2014 cycles of the National Health and Nutrition Examination Survey conducted by the Centers for Disease Control and Prevention of the USA. PARTICIPANTS A representative American population aged ≥60 years. MEASUREMENTS L-theobromine was treated as a log transform and dichotomous form (the highest quantile vs. others). Cognitive function was measured using four tests: Consortium to Establish a Registry for Alzheimer's Disease Word Learning tests, Consortium to Establish a Registry for Alzheimer's Disease delayed recall test, animal fluency test, and digit symbol substitution test. We conducted multiple regression analyses and subgroup analyses to study the association between theobromine and cognitive performance. Basic characteristics, lifestyle factors, disease history, and nutritional intake were adjusted for in these models. RESULTS A total of 2,845 participants were included in the study. The highest quantile of L-theobromine intake was positively associated with sores of delayed recall, animal fluency, and digit symbol substitution tests (β, 95% confidence interval, P: 0.11, -0.00-0.30, 0.049; 0.50, 0.02-0.99, 0.043; 1.55, 0.33-2.77, 0.015; respectively) in the fully adjusted model, but not with immediate recall score (β=0.13, 95% confidence interval -0.16-0.43, P=0.361). Subgroup analyses showed that L-theobromine intake was associated with cognitive performance in the highest quantile of caffeine intake. CONCLUSIONS Daily theobromine intake was associated with cognitive performance in a large nationally representative population. However, further research is needed to corroborate our findings.

Abstract
We report a new optofluidic resonating phenomenon that naturally links the optical radiation pressure, total internal reflection, capillary wave, and Rayleigh-Plateau instability together. When a transparent liquid jet is radiated by a focused continuous wave laser beam, the highly ordered periodic jet breakup is unexpectedly triggered and maintained. The capillary wave enables the liquid-gas interface to serve as a rotating mirror reflecting the laser beam in a wide range of angles, including the critical angle for total internal reflection. The liquid jet acts as an optical waveguide to periodically transmit the laser beam to the upstream of the jet. The periodic optical beam transmittance inside the liquid jet exerts time-dependent optical pressure to the jet that triggers the Rayleigh-Plateau instability. The jet breakup process locks in at the frequency corresponding to the peak growth rate of the Rayleigh-Plateau instability of the liquid jet, which agrees with the prediction from the dispersion relation of a traveling liquid jet.

Abstract
Objective: To establish a dental fluorosis model of SD rats with various degrees, to observe the microstructures of enamel samples under scanning electron microscope and to clarify the changes of enamel microstructures with various degrees of dental fluorosis, so as to provide clinical reference for the treatment of patients with moderate and severe dental fluorosis. Methods: Thirty male SD rats (6 weeks of age) were randomly divided into 3 groups with 10 rats in each group. The control group was fed with deionized water without fluoride, the low fluoride group was fed with 50 mg/L NaF deionized water and the high fluoride group was fed with 100 mg/L NaF deionized water in order to establish the dental fluorosis model of rats. After feeding for 6 weeks, the rats were sacrificed and the mandibular incisor teeth were collected and recorded. The surface and sagittal plane of each tooth were observed by scanning electron microscopy and the enamel thickness was measured. Results: In the control group, the enamel color was brown yellow. Enamel color discoloration occurred both in low-fluoride group and high-fluoride group. The enamel color in low-fluoride group was mostly yellow and white striped while in high-fluoride group was mostly chalky white. Under electronic microscope, the enamel rods were alternately arranged and their structure was clear and plump in the control group. The enamel rods of moderate fluorosis were arranged in a straight orientation like tips of bamboo shoots. The enamel rods of severe fluorosis, however, became thinner and the tips of rods were broken. In the control group, sagittal images of enamel turned out to be a dense outer structure with clear boundaries among the inner. The structure of the middle layer was reticulated showing a clear boundary with middle and outer layers. The structure of enamel rods in the inner layers was arranged vertically and horizontally. In the moderate fluorosis group, the outer layer of the enamel became thinner and the middle layer disappeared although the boundary between the outer and middle layers was still clear. In the inner layer, the vertically arranged enamel rods seemed still clear, however the horizontal enamel rods disappeared. In the severe fluorosis group, the outer layer could not be traced. The middle layer was exposed to the air and the inner enamel rods contracted. The inner layers of the enamel had gradually become thinner with the development of the dental fluorosis. The thicknesses of inner layers in control, moderate and the severe groups were (180.71±7.01), (157.10±11.04) and (121.10±12.56) μm respectively. As for the thicknesses of the full layers in the above mentioned three groups, the same trend was observed. The thicknesses, in order of the severity of dental fluorosis, were (241.54±7.76), (207.42±14.36) and (143.79±14.60) μm. Conclusions: With the development of dental fluorosis, the outer enamel layers became thinner or disappeared and the inner enamel layers became thinner or lost its normal structure as well. It is highly recommended that the resin penetration could be used for the proper treatment of moderate and severe dental fluorosis and the strong bleaching and the micro-grinding should be used cautiously.

Abstract
Objective To assess whether miR-204 and HA affect A549 cell injury induced by lipopolysaccharide. Material and Methods. A549 cells were treated with hirsutanol A, and cell damage was induced by LPS followed by analysis of cell proliferation by CCK-8, cell apoptosis by flow cytometry, apoptosis-related protein expression by western blot, downstream target of miR-20 by dual-luciferase reporter gene, and inflammatory factors by ELISA and PCR. Results LPS can significantly inhibit the viability of A549 cells, induce cell apoptosis, and promote the release of IL-6, IL-1β, and TNF-α, while HA pretreatment can target FOXK2 by upregulating miR-204 levels, thereby alleviating apoptosis and promoting cell viability and at the same time inhibiting the release of inflammatory factors by inhibiting the activation of NF-κB. Conclusions miR-204 participates in the protection of HA acute lung injury by targeting FOXK2.

Abstract
Schisandrin A (Sch A) has a protective effect on cardiomyocytes. Circulating miR-155 levels are related to chronic heart failure (CHF). The present study aimed to clarify the role and the molecular mechanism of Sch A in CHF. C57BL/6JGpt mice were used for an isoproterenol (ISO)-induced CHF model to collect heart samples. Echocardiography was employed to detect heartbeat indicators. The degree of myocardial hypertrophy was evaluated based on the measurement of heart weight (HW), body weight (BW) and tibia length (TL) and the observation using hematoxylin-eosin staining. Sprague-Dawley rats were purchased for the separation of neonatal rat ventricular myocytes (NRVMs), which were treated with ISO for 24 h. Transfection regulated the level of miR-155. The viability of NRVMs was detected via MTT assay. The mRNA and protein levels were measured via reverse transcription-quantitative PCR and western blotting and immunofluorescence was used to detect the content of α-smooth muscle actin (α-SMA). Treatment with ISO resulted in rising left ventricular posterior wall thickness, intra-ventricular septum diastole, left ventricular end diastolic diameter, left ventricular end systolic diameter, HW/BW, HW/TL and falling ejection fraction and fractional shortening, the trend of which could be reversed by Sch A. Sch A ameliorated myocardial hypertrophy in CHF mice. In addition, Sch A inhibited ISO-induced upregulated expressions of atrial natriuretic peptide, B-type natriuretic peptide, B-myosin heavy chain and miR-155 in myocardial tissue. Based on the results in vitro, Sch A had no significant effect on the viability of NRVMs when its concentration was <24 µmol/l. Sch A inhibited the levels of miR-155, α-SMA and the phosphorylation levels of AKT and cyclic AMP response-element binding protein (CREB) in ISO-induced NRVMs, which was reversed by the upregulation of miR-155. Schisandrin A mediated the AKT/CREB signaling pathway to prevent CHF by regulating the expression of miR-155, which may shed light on a possible therapeutic target for CHF.

Increasing evidence suggests that patients scheduled for invasive cardiac procedures such as coronary angiography / PCI feel insufficiently informed about the planned procedure.
Purpose
To improve the Patient Informed Consent (IC) before coronary angiography by using “medical graphic narratives” (patient comic) that illustrate central IC-related aspects in a simple and understandable manner.
Methods
A patient comic illustrating central steps of the procedure, risks, treatment alternatives and behavioural measures was created in collaboration with professional scientific visual communicators. In a randomised, controlled, prospective trial, we included 121 patients undergoing coronary angiography/PCI. Patients were randomised to a group that was informed about the procedure using the usual Patient IC approach (official consent form and conversation with physician; Control group) or a group that additionally obtained a patient comic for reading (graphic illustrations of central IC aspects based on the official consent form; Comic group). Patient Reported Outcome Measures (PROMs), i.e. satisfaction with and perceived quality of the patient IC, were tested in both groups comparing single items of the Client Satisfaction Questionnaire-8 (CSQ-8) and self-designed single items in both IC groups. Differences were compared using the Fisher's exact test. A p-value <0.05 was considered statistically significant.
Results
PROMs showed significant benefits in favour of the Comic group: Quality of the patient IC was perceived to be “very good” in 45.0% of the Comic group compared to 24.9% of patients in the Control group (p=0.023). Only 23.0% of the patients in the Control group, compared to 40.0% in the Comic group, stated that the IC procedure completely met their expectations (p=0.012). 57.4% in the Control group and 76.7% in the Comic group stated that all of their questions were satisfactorily adressed before the procedure (p=0.015). 43.3% in the Comic group, in contrast to 18.0% in the Control group, declared to feel “very satisfied” with the obtained IC procedure (p=0.002). The acceptance of the patient comic was very high: no patient (0%) expressed feelings of not being taken seriously by reading the patient comic.
Conclusions
Our data confirm pronounced limitations of the usual Patient IC practice before coronary angiography. The use of a patient comic that narratively illustrates central steps of the procedure positively impacts on patient-centered endpoints and significantly improves the patient IC procedure.

Abstract
A novel high-resolution x-ray spectrometer for point-like emission sources has been developed using a crystal shape having both a variable major and a variable minor radius of curvature. This variable-radii sinusoidal spiral spectrometer (VR-Spiral) allows three common spectrometer design goals to be achieved simultaneously: 1. reduction of aberrations and improved spectral (energy) resolution, 2. reduction of source size broadening, and 3. use of large crystals to improve total throughput. The VR-Spiral concept and its application to practical spectrometer design are described in detail. This concept is then used to design a spectrometer for an extreme extended x-ray absorption fine structure experiment at the National Ignition Facility looking at the Pb L3 absorption edge at 13.0352 keV. The expected performance of this VR-Spiral spectrometer, both in terms of energy resolution and spatial resolution, is evaluated through the use of a newly developed raytracing tool, xicsrt. Finally, the expected performance of the VR-Spiral concept is compared to that of spectrometers based on conventional toroidal and variable-radii toroidal crystal geometries showing a greatly improved energy resolution.

Abstract
OBJECTIVE To investigate the effects of RNA interference of long noncoding RNA FOXCUT on epithelial mesenchymal transformation and mitochondrial function in nasopharyngeal carcinoma (NPC) cells. METHODS FOXCUT expression levels were detected by RT-PCR in tumor tissues and adjacent tissues from 50 patients with NPC and in NP69, CNE1, CNE2, SUNE2, HER2 and 5-8F cell lines. CNE1 cells were transfected with a short hairpin RNA (shRNA) targeting FOXCUT or a negative control RNA construct (shRNA-NC), and the changes in cell proliferation and morphology were assessed with CCK8 assay, clone formation assay and microscopic observation. An immunofluorescence assay was used to examine the vimentin-positive cells, and the levels of SOD, MDA and LDH in the cells were detected. The changes of mitochondrial membrane potential were detected with flow cytometry, and the expression levels of E-cad, N-cad, vimentin, Bax, Bcl-2, caspase-3 and c-Myc in the cells were detected with Western blotting. RESULTS The expression level of FOXCUT was significantly increased in NPC tissues as compared with the adjacent tissues (P < 0.001). Compared with NP69 cells, CNE1, CNE2, SUNE2, HER2 and 5-8F cells all exhibited significantly increased expressions of FOXCUT (P < 0.001). In CNE1 cells, transfection with FOXCUT shRNA significantly inhibited cell proliferation and clone formation (P < 0.001), and caused obvious changes in cell morphology. FOXCUT knockdown significantly decreased the expressions of N-cad and vimentin, increased E- cad expression and the contents of MDA and LDH (P < 0.05), reduced vimentin- positive cells and the activity of SOD, and caused a shift of red fluorescent cells to green fluorescent cells and an increased percentage of green fluorescent cells. FOXCUT knockdown also resulted in significantly increased expressions of Bax/Bcl2 and cleaved Cas3/Cas3 and a lowered expression of c-Myc. CONCLUSIONS Interference of FOXCUT can inhibit the proliferation and epithelial-mesenchymal transformation, enhance oxidative stress, induce mitochondrial function injury, and promote apoptosis in NPC cells, suggesting the potential of FOXCUT interference for targeted treatment of NPC.

Abstract
Effective removal of dental plaque is a key measure to prevent and control common oral diseases and to maintain the long-term effect of dental prostheses. The methods of oral plaque control are mainly depending on mechanical measures, including regular toothbrushing, interdental cleaning and oral irrigation. Toothbrushing is the most common and effective method for mechanical removal of dental plaque.How ever the effect of toothbrushing alone to remove dental plaque is limited. It is necessary to control the interdental plaque using tools such as dental floss and interdental brushes. Oral irrigation is an assistant method to improve oral hygiene. Toothbrushing combined with the use of oral irrigator can significantly improve the removal rate of dental plaque. The present article reviews the research progress of the mechanical plaque control methods and their application results.

Abstract
Objective: To investigate the sonographic features of primary thyroid lymphoma (PTL) and to evaluate the clinical significance of ultrasound-guided core needle biopsy (US-CNB) in PTL. Methods: A total of 24 patients with suspected PTL in Sir Run Run Shaw Hospital from January 2013 to June 2018 were analyzed retrospectively. All cases were confirmed by pathology, of them 23 patients received US-CNB and 1 patient chose operation without US-CNB, including 5 males and 19 females, aged from 39 to 75 years old. The effectiveness and safety of 23 patients with US-CNB were evaluated, and the sonographic features of 20 patients with PTL diagnosed by pathology were analyzed. Descriptive statistical methods were used in the study. Results: In the 23 patients with suspected PTL underwent US-CNB, 18 patients were diagnosed as PTL, 4 patients were respectively diagnosed as subacute thyroiditis, anaplastic carcinoma, Hashimoto's thyroiditis, and fibro thyroiditis, and the another patient was hard to diagnose by US-CNB and then was diagnosed as PTL by surgical biopsy. The success rate of US-CNB for diagnosis of PTL was 18/19, and no severe complications occurred in the patients with US-CNB. The other case was diagnosed as PTL by surgical biopsy without US-CNB. Sonographic features of 20 cases with PTL (18 cases diagnosed by US-CNB and 2 cases by surgery or surgery biopsy) were as follows: (1) Most nodules had irregular shapes and unsmooth margins; (2) Hypoechoic or markedly hypoechoic nodules with honeycombed or cord structures were observed in most cases; (3) Calcification was rare; (4) Multiple lesions were common; (5) Abundant intralesional vascularization was commonly observed; (6) Most cases had intensification of posterior acoustic enhancement; (7) Thyroid gland enlargement or with irregular shape; and (8) PTL often accompanied with lymph nodes enlargement in lateral neck or central region. Conclusion: PTL has certain sonographic features, with assistance of US-CNB, more accurate diagnosis of PTL can be obtained.

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
BACKGROUND Poststroke depression is a common secondary mental disorder after stroke, which increases the recurrence rate and mortality rate after stroke and hinders the recovery of function. As a combination therapy, simple acupuncture combined with fluoxetine has achieved good clinical effect, but there is a lack of evidence-based medicine. The purpose of this study is to evaluate the efficacy and safety of acupuncture combined with fluoxetine in the treatment of poststroke depression by meta-analysis. METHODS Search Chinese and English databases: China national knowledge infrastructure, VP information Chinese Journal Service Platform, Wanfang, the China Biomedical Database, PubMed, Embase, the Cochrane Library, and web of science. A randomized controlled trial of simple acupuncture combined with fluoxetine in the treatment of poststroke depression will be selected. The retrieval time is of the establishment of the database in January 2021. Selected literature is extracted and deleted by 2 researchers, and the quality of the included literature is evaluated. The included literature is analyzed by Meta with RevMan5.3 software. RESULTS In this study, the efficacy and safety of acupuncture combined with fluoxetine in the treatment of post-stroke depression are evaluated by Hamilton Depression scale (HAMD) and its reduction rate, Treatment Emergency Symptom Scale, Self-rating Depression Scale, and Activities of Daily living scale. CONCLUSION This study will provide reliable evidence-based evidence for the clinical application of acupuncture combined with fluoxetine in the treatment of post-stroke depression.

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.
