Abstract
BACKGROUND The outcome of patients with resectable mucosal melanoma is poor. Toripalimab combined with axitinib has shown impressive results in metastatic mucosal melanoma with an objective response rate of 48.3% and a median progression-free survival of 7.5 months in a phase Ib trial. It was hypothesized that this combination administered in the neoadjuvant setting might induce a pathologic response in resectable mucosal melanoma, so we conducted this trial. PATIENTS AND METHODS This single-arm phase II trial enrolled patients with resectable mucosal melanoma. Patients received toripalimab 3 mg/kg once every 2 weeks (Q2W) plus axitinib 5 mg two times a day (b.i.d.) for 8 weeks as neoadjuvant therapy, then surgery and adjuvant toripalimab 3 mg/kg Q2W starting 2 ± 1weeks after surgery for 44 weeks. The primary endpoint was the pathologic response rate according to the International Neoadjuvant Melanoma Consortium recommendations. RESULTS Between August 2019 and October 2021, 29 patients were enrolled and received treatment, of whom 24 underwent resection. The median follow-up time was 34.2 months (95% confidence interval 20.4-48.0 months). The pathologic response rate was 33.3% (8/24; 4 pathological complete responses and 4 pathological partial responses). The median event-free survival for all patients was 11.1 months (95% confidence interval 5.3-16.9 months). The median overall survival was not reached. Neoadjuvant therapy was tolerable with 8 (27.5%) grade 3-4 treatment-related adverse events and no treatment-related deaths. Tissue samples of 17 patients at baseline and after surgery were collected (5 responders and 12 nonresponders). Multiplex immunohistochemistry demonstrated a significant increase in CD3+ (P = 0.0032) and CD3+CD8+ (P = 0.0038) tumor-infiltrating lymphocytes after neoadjuvant therapy, particularly in pathological responders. CONCLUSIONS Neoadjuvant toripalimab combined with axitinib in resectable mucosal melanoma demonstrated a promising pathologic response rate with significantly increased infiltrating CD3+ and CD3+CD8+ T cells after therapy.

Abstract
Multiple sclerosis (MS) is an autoimmune disease characterized by the infiltration of immune cells and demyelination in the central nervous system (CNS). Experimental autoimmune encephalomyelitis (EAE) serves as a prototypic animal model for studying MS. In this study, we aimed to investigate the role of CD4 T cells in the initiation and relapse of EAE, focusing on the activation phase and immune response. To create the EAE mice model, female mice were immunized with myelin oligodendrocyte glycoprotein (MOG)35-55 emulsified with complete Freund's adjuvant (CFA). Clinical scores were assessed daily, and results demonstrated that mice in the EAE group exhibited a classic relapsing-remitting pattern. Hematoxylin-eosin (H&E) and luxol fast blue (LFB) staining analysis revealed significant infiltration of inflammatory cells in the CNS and demyelination in EAE mice. Regarding the activation phase, both CD4+CD69+ effector T (Teff) cells and CD4+CD44+CD62L- effector memory T (Tem) cells may contribute to the initiation of EAE, however, the relapse stage was probably dominated by CD4+CD44+CD62L- Tem cells. Additionally, in terms of immune function, helper T (Th)1 cells are primarily involved in initiating the EAE. However, both Th1 and Th17 cells contribute to the relapse stage, and the immunosuppressive function of regulatory T (Treg) cells was inhibited during the EAE pathological process.

Abstract
Lung cancer is a major public health problem worldwide, with high rates of morbidity and mortality. It often coexists with chronic obstructive pulmonary disease (COPD), the diagnosis and management of which often receives insufficient attention. In particular, the presence of COPD has significant implications for the clinical management of lung cancer patients. This review systematically assesses the influence of COPD on the efficacy of immunotherapy and the occurrence of immune-related adverse events in patients with lung cancer, identifies existing challenges and proposes avenues for future research in this field.

Abstract
Objective: To observe the efficacy and adverse reactions of a combination therapy regimen based on bortezomib and glucocorticoids in recurrent/refractory immune thrombocytopenic purpura (iTTP) . Methods: Six patients with recurrent/refractory TTP were included and treated with a glucocorticoid and two courses of bortezomib-based regimen. The clinical remission status of patients, changes in ADAMTS13 activity/ADAMTS13 inhibitor, and the occurrence of treatment-related adverse reactions were observed. Results: Of the 6 patients, 2 were males and 4 were females, with a median age of 21.5 (18-68) years. Refractory TTP was found in 1 case and recurrent TTP in 5 cases. Glucocorticoids were administered with reference to prednisone at 1 mg·kg(-1)·d(-1), and gradually reduced in dosage after achieving clinical remission. Bortezomib is subcutaneously administered at 1.3 mg/m(2) on days 1, 4, 8, and 11 with a 28-day treatment course consisting of 2 courses. Six patients achieved clinical remission after receiving bortezomib as the main treatment. ADMATS13 activity returned to normal in all patients with TTP after treatment, and the ADAMTS13 inhibitor turned negative. Thrombocytopenia is the most common adverse reaction after treatment, with other adverse reactions, including peripheral neuritis and abdominal pain, but ultimately all patients returned to normal. In a median follow-up of 26 (9-41) months, 5 patients maintained sustained remission, and 1 patient relapsed after 16 months of bortezomib treatment. Conclusion: Combination therapy of bortezomib and glucocorticoids has a satisfactory therapeutic effect and controllable adverse reactions for recurrent/refractory iTTP.

Abstract
Objective: To report the clinical manifestations and laboratory features of five patients with congenital thrombotic thrombocytopenic purpura (cTTP) and explore its standardized clinical diagnosis and treatment along with a review of literature. Methods: Clinical data of patients, such as age of onset, disease manifestation, personal history, family history, and misdiagnosed disease, were collected. Treatment outcomes, therapeutic effects of plasma infusion, and organ function evaluation were observed. The relationship among the clinical manifestations, treatment outcomes, and ADAMTS13 gene mutation of patients with cTTP was analyzed. Additionally, detection of ADAMTS13 activity and analysis of ADAMTS13 gene mutation were explored. Results: The age of onset of cTTP was either in childhood or adulthood except in one case, which was at the age of 1. The primary manifestations were obvious thrombocytopenia, anemia, and different degrees of nervous system involvement. Most of the patients were initially suspected of having immune thrombocytopenia. Acute cTTP was induced by pregnancy and infection in two and one case, respectively. ADAMTS13 gene mutation was detected in all cases, and there was an inherent relationship between the mutation site, clinical manifestations, and degree of organ injury. Therapeutic or prophylactic plasma transfusion was effective for treating cTTP. Conclusions: The clinical manifestations of cTTP vary among individuals, resulting in frequent misdiagnosis that delays treatment. ADAMTS13 activity detection in plasma and ADAMTS13 gene mutation analysis are important bases to diagnose cTTP. Prophylactic plasma transfusion is vital to prevent the onset of the disease.

Abstract
Between August and September, 2021, this study included 605 SARS-CoV-2 natural infection cases and 589 SARS-CoV-2 breakthrough cases from Nanjing and Yangzhou, as well as 690 inactivated COVID-19 vaccine recipients from Changzhou, China. In SARS-CoV-2 natural infection cases, the age range was 19-91 years (median age: 66 year), and the medians(Q1,Q3) of IgG titers were 0.19 (0.06-1.31), 3.70 (0.76-69.48), 15.31 (2.59-82.16), 4.41 (0.99-31.74), 2.31 (0.75-13.83), 2.28 (0.68-9.94) and 2.80 (1.00-9.53) at one to seven weeks after SARS-CoV-2 infection, respectively. In SARS-CoV-2 breakthrough cases, the age range was 18-76 years (median age: 45 year), and the medians(Q1,Q3)of IgG titers were 1.93 (0.34-26.67), 38.87 (7.90-121.0), 75.09 (11.85-123.70), 21.97 (5.20-95.58), 13.97 (3.47-46.82), 9.56 (2.48-33.38) and 4.38 (1.87-11.00) at one to seven weeks after SARS-CoV-2 infection, respectively. In inactivated COVID-19 vaccine recipients, the age range was 18-87 years (median age: 47 years), and the medians(Q1,Q3)of IgG titers were 16.22 (15.84-33.42), 5.35 (2.96-13.23), 3.30 (2.18-6.18), 3.14 (1.16-5.70), 2.77 (1.50-4.52), 2.72 (1.76-4.36), 2.01 (1.27-3.51) and 1.94 (1.35-3.09) at one to eight months after SARS-CoV-2 infection, respectively. The results suggested that IgG antibodies increased gradually within two weeks after SARS-CoV-2 infection, then declined gradually at three to seven weeks in SARS-CoV-2 natural infection cases. In SARS-CoV-2 breakthrough cases, IgG antibodies increased rapidly within two weeks, then declined gradually at three to seven weeks after SARS-CoV-2 infection. Additionally, IgG antibodies decreased rapidly within three months, then decreased gradually and remained at a low level within three months after immunization.

We performed an epigenome-wide association study (EWAS) by combining with the waist-to-hip ratio (WHR)-discordant monozygotic (MZ) twin design in an attempt to identify genetically independent DNA methylation marks associated with abdominal obesity in Northern Han Chinese and to determine the causation underlying. METHODS A total of 60 WHR discordant MZ twin pairs were selected from the Qingdao Twin Registry, China. Generalized estimated equation (GEE) model was used to regress the methylation level of CpG sites on WHR. The Inference about Causation through Examination of FAmiliaL CONfounding (ICE FALCON) was used to assess the temporal relationship between methylation and WHR. Gene expression analysis was conducted to validate the results of differentially methylated analyses. RESULTS EWAS identified 92 CpG sites with the level of P < 10 - 4 which were annotated to 32 genes, especially CADPS2, TUSC5, ZCCHC14, CORO7, COL23A1, CACNA1C, CYP26B1, and BCAT1. ICE FALCON showed significant causality between DNA methylation of several genes and WHR (P < 0.05). In region-based analysis, 14 differentially methylated regions (DMRs) located at 15 genes (slk-corrected P < 0.05) were detected. The gene expression analysis identified the significant correlation between expression levels of 5 differentially methylated genes and WHR (P < 0.05). CONCLUSIONS Our study identifies the associations between specific epigenetic variations and WHR in Northern Han Chinese. These DNA methylation signatures may have value as diagnostic biomarkers and provide novel insights into the molecular mechanisms of pathogenesis.

Abstract
Objective: To investigate the diagnostic value of rapid antigen test based on colloidal gold immunochromatographic assay for the detection of SARS-CoV-2 infection in symptomatic patients. Methods: From May 20 to June 5 2022, 76 hospitalized children and their 55 accompanying family members with confirmed SARS-CoV-2 infection in the COVID-19 isolation unit of the Children's Hospital of Fudan University (designated referral hospital for SARS-CoV-2 infection in Shanghai) enrolled. Their nasopharyngeal swab specimens were consecutively collected. The samples were tested for SARS-CoV-2 nucleic acid by real-time quantitative. SARS-CoV-2 antigen was tested by immunochromatography. The correlation between the antigen detection results and the change of the cycle threshold (Ct) values were evaluated, as well as the sensitivity and specificity of SARS-CoV-2 antigen detection at different periods after the onset of the disease. Kappa consistency test was conducted to investigate the consistency between the 2 diagnostic methods. Results: Of the enrolled SARS-CoV-2 symptomatic infections, 76 were children, including 41 males and 35 females, with an age of 5 (2, 9) years; 55 were accompanying families, including 8 males and 47 females, with an age of 38 (32, 41) years. All 478 samples were simultaneously tested for SARS-CoV-2 antigen and nucleic acid. In any period from disease onset to negative conversion of viral nucleic acid, the overall sensitivity of the rapid antigen test was 48.2% (119/247), the specificity was 98.3% (227/231), and antigen test and nucleic acid test showed moderate consistency (κ=0.46, P<0.05). The sensitivity of antigen test was 100% (82/82) when the Ct value was ≤25. And the sensitivity of antigen test was 8/10, 4/15 and 8.3% (3/36) when the Ct value was 26, 30 and 35, respectively. All antigen tests were negative when Ct value was >35. During the period of 1-2 days, 3-5 days, 6-7 days, 8-10 days and >10 days after onset, the sensitivity and specificity of SARS-CoV-2 antigen test were 5/8 and 5/5, 90.2% (37/41) and 5/5, 88.9% (24/27) and 2/5, 45.0% (36/80) and 94.1% (32/34), 18.7% (17/91) and 98.9% (183/185) respectively. The Ct values of nasopharyngeal swabs were<26 during 2 to 7 days after onset, 28.7±5.0 on day 8, 34.5±2.9 on day 13 and > 35 after 14 days, respectively. Conclusion: SARS-CoV-2 antigen test in the patients with SARS-CoV-2 infection shows acceptable sensitivity and specificity within 7 days after onset of disease, and the sensitivity was positively correlated with viral load and negatively correlated with onset time.

Abstract
Objective: To investigate the ABC prognostic classification and the updated version of Model for End-stage Liver Disease (MELD) score 3.0 and Chinese Group on the Study of Severe Hepatitis B ACLF Ⅱ score (COSSH-ACLF Ⅱ score) to evaluate the prognostic value in acute-on-chronic liver failure (ACLF). Methods: ABC classification was performed on a 1 409 follow-up cohorts. The area under the receiver operating characteristic curve (AUROC) was used to analyze MELD, MELD 3.0, COSSH-Ⅱ and COSSH-Ⅱ score after 3 days of hospitalization (COSSH-Ⅱ-3d). The prognostic predictive ability of patients were evaluated for 360 days, and the prediction differences of different classifications and different etiologies on the prognosis of ACLF were compared. Results: The survival curve of 1 409 cases with ACLF showed that the difference between class A, B, and C was statistically significant, Log Rank (Mantel-Cox) χ2=80.133, P<0.01. Compared with class A and C, χ2=76.198, P<0.01, the difference between class B and C, was not statistically significant χ2=3.717, P>0.05. AUROC [95% confidence interval (CI)] analyzed MELD, MELD 3.0, COSSH-Ⅱ and COSSH-Ⅱ-3d were 0.644, 0.655, 0.817 and 0.839, respectively (P<0.01). COSSH-Ⅱ had better prognostic predictive ability with class A ACLF and HBV-related ACLF (HBV-ACLF) for 360-days, and AUROC (95% CI) were 0.877 and 0.881, respectively (P<0.01), while MELD 3.0 prognostic predictive value was not better than MELD. Conclusion: ACLF prognosis is closely related to ABC classification. COSSH-Ⅱ score has a high predictive value for the prognostic evaluation of class A ACLF and HBV-ACLF. COSSH-Ⅱ score has a better prognostic evaluation value after 3 days of hospitalization, suggesting that attention should be paid to the treatment of ACLF in the early stage of admission.

Abstract
Objective: To explore the influencing factors of health-related quality of life (HRQoL) in patients with knee osteoarthritis, and to analyze the non-surgical treatment of knee osteoarthritis. Methods: Demographic variables, treatment modalities, imaging data, and 12-item short form health survey (SF-12) scores of patients with knee osteoarthritis in orthopedic outpatient departments of five hospitals in Beijing from December 2017 to November 2018 were collected to analyze influencing factors of HRQoL and non-surgical treatment. Results: A total of 2 034 patients were included. There were 530 males (26.1%) and 1 504 females (73.9%), with a mean age of (59.17±10.22) years. In terms of physical quality of life, female patients with knee osteoarthritis had lower physical components summary (PCS) compared with male patients (β=-0.521, P=0.036); patients aged ≥64 years had lower PCS than those aged<55 years (β=-0.636, P=0.026). Patients with an education of more than 12 years had higher PCS than those with less than 10 years (β=1.063, P<0.001). Compared to patients with mild clinical symptoms, the PCS of patients with moderate clinical symptoms was lower (β=-0.860, P=0.002), while the PCS of those with severe clinical symptoms was much lower (β=-1.126, P<0.001). Patients treated with combination therapy had higher PCS than untreated patients (β=0.731, P=0.005). In terms of mental quality of life, compared to patients engaged in sedentary work, the mental components summary (MCS) of patients engaged in mild manual labor jobs was lower (β=-0.712, P=0.015); Compared to patients with a Charson comorbidity index of 0, patients with a Charlson comorbidity index ≥ 2 had lower MCS (β=-1.183, P=0.007). In the past 12 months, 648 (31.9%), 143 (7.0%), 406 (20.0%), 680 (33.4%), 343 (16.9%), 681 (33.5%), 170 (8.4%) patients had used non-steroid anti-inflammatory drugs (NSAIDs), acetaminophen, glucosamine/chondroitin formulations, physical therapy, articular cavity puncture injection, traditional Chinese medicine treatment and exercise therapy, respectively. Total of 451 patients (22.2%) received monotherapy and 889 patients (43.7%) received combination therapy. Conclusions: The major non-surgical treatment methods for patients with knee osteoarthritis in Beijing are NSAIDs, physiotherapy and traditional Chinese medicine. Combination therapy is used more frequently than monotherapy. Physical quality of life is related to gender, age, education, severity of symptoms and treatment, while mental quality of life is related to occupational labor and comorbidities.

Abstract
Thrombosis is the main cause of the development and progression of venous thromboembolism(VTE). Anticoagulant therapy is the cornerstone for the prophylaxis and treatment of VTE, and it has evolved mainly through indirect thrombin inhibitors, direct thrombin inhibitors, vitamin K antagonists and new oral anticoagulants. Although safety is improving, the risk of bleeding remains a non-negligible side effect of current anticoagulation therapy, especially in patients with higher bleeding risk. Studies of the coagulation pathway have found that FXI is not involved in the initiation of hemostasis, but promotes thrombus growth and stabilization primarily through feedback activation of FⅪ by thrombin. Further studies have found that inhibition of FⅪ significantly inhibits thrombus formation and only affects hemostasis slightly. Recent studies have confirmed the efficacy and safety of FⅪ inhibitors in the prevention of VTE in patients after knee replacement. In addition, the safety of FⅪ inhibitors has been further confirmed by the studies of FⅪ inhibitors in people with higher bleeding risk. FⅪ inhibitors may be the most promising anticoagulant drugs in the next decade.

Abstract
Objective: To investigate the effect and mechanism of sacubitril/valsartan on left ventricular remodeling and cardiac function in rats with heart failure. Methods: A total of 46 SPF-grade male Wistar rats weighed 300-350 g were acclimatized to the laboratory for 7 days. Rats were then divided into 4 groups: the heart failure group (n=12, intraperitoneal injection of adriamycin hydrochloride 2.5 mg/kg once a week for 6 consecutive weeks, establishing a model of heart failure); heart failure+sacubitril/valsartan group (treatment group, n=12, intragastric administration with sacubitril/valsartan 1 week before the first injection of adriamycin, at a dose of 60 mg·kg-1·d-1 for 7 weeks); heart failure+sacubitril/valsartan+APJ antagonist F13A group (F13A group, n=12, adriamycin and sacubitril/valsartan, intraperitoneal injection of 100 μg·kg-1·d-1 APJ antagonist F13A for 7 weeks) and control group (n=10, intraperitoneal injection of equal volume of normal saline). One week after the last injection of adriamycin or saline, transthoracic echocardiography was performed to detect the cardiac structure and function, and then the rats were executed, blood and left ventricular specimens were obtained for further analysis. Hematoxylin-eosin staining and Masson trichrome staining were performed to analyze the left ventricular pathological change and myocardial fibrosis. TUNEL staining was performed to detect cardiomyocyte apoptosis. mRNA expression of left ventricular myocardial apelin and APJ was detected by RT-qRCR. ELISA was performed to detect plasma apelin-12 concentration. The protein expression of left ventricular myocardial apelin and APJ was detected by Western blot. Results: Seven rats survived in the heart failure group, 10 in the treatment group, and 8 in the F13A group. Echocardiography showed that the left ventricular end-diastolic diameter (LVEDD) and the left ventricular end-systolic diameter (LVESD) were higher (both P<0.05), while the left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were lower in the heart failure group than in the control group (both P<0.05). Compared with the heart failure group, rats in the treatment group were featured with lower LVEDD and LVESD (both P<0.05), higher LVEF and LVFS (both P<0.05), these beneficial effects were reversed in rats assigned to F13A group (all P<0.05 vs. treatment group). The results of HE staining showed that the cardiomyocytes of rats in the control group were arranged neatly and densely structured, the cardiomyocytes in the heart failure group were arranged in disorder, distorted and the gap between cells was increased, the cardiomyocytes in the treatment group were slightly neat and dense, and cardiomyocytes in the F13A group were featured similarly as the heart failure group. Masson staining showed that there were small amount of collagen fibers in the left ventricular myocardial interstitium of the control group, while left ventricular myocardial fibrosis was significantly increased, and collagen volume fraction (CVF) was significantly higher in the heart failure group than that of the control group (P<0.05). Compared with the heart failure group, the left ventricular myocardial fibrosis and the CVF were reduced in the treatment group (both P<0.05), these effects were reversed in the F13A group (all P<0.05 vs. treatment group). TUNEL staining showed that the apoptosis index (AI) of cardiomyocytes in rats was higher in the heart failure group compared with the control group (P<0.05), which was reduced in the treatment group (P<0.05 vs. heart failure group), this effect again was reversed in the F13A group (P<0.05 vs. treatment group). The results of RT-qPCR and Western blot showed that the mRNA and protein levels of apelin and APJ in left ventricular myocardial tissue of rats were downregulated in heart failure group (all P<0.05) compared with the control group. Compared with the heart failure group, the mRNA and protein levels of apelin and APJ were upregulated in the treatment group (all P<0.05), these effects were reversed in the F13A group (all P<0.05 vs. treatment group). ELISA test showed that the plasma apelin concentration of rats was lower in the heart failure group compared with the control group (P<0.05); compared with the heart failure group, the plasma apelin concentration of rats was higher in the treatment group (P<0.05), this effect was reversed in the F13A group (P<0.05 vs. treatment group). Conclusion: Sacubitril/valsartan can partially reverse left ventricular remodeling and improve cardiac function in rats with heart failure through modulating Apelin/APJ pathways.

Abstract
BACKGROUND No standard of care for mucosal melanoma (MM) in the adjuvant setting has been established. Meanwhile, relapse-free survival (RFS) is only about five months after surgery alone. This phase II trial aimed to compare toripalimab vs. high-dose interferon-α2b (HDI) as an adjuvant therapy for resected MM. PATIENTS AND METHODS From July 2017 to May 2019, 145 patients with resected MM were randomized (1:1) to receive HDI (N = 72) or toripalimab (N = 73) for one year until disease relapse/distant metastasis, unacceptable toxicity, or withdrawal of consent. The primary endpoint was RFS. The secondary endpoints included distant metastasis-free survival (DMFS), overall survival (OS), and safety. RESULTS After a median follow-up of 26.3 months, the numbers of RFS, OS, and DMFS events were 51 vs. 46, 33 vs. 29, and 49 vs. 44 in the toripalimab arm and the HDI arm, respectively. The median RFS were 13.6 (95%CI: 8.31-19.02) months and 13.9 (95%CI: 8.28-19.61) months in the toripalimab arm and HDI arm, respectively. The DMFS was not significantly different between the two arms (HR: 1.00, 95%CI: 0.65-1.54). The median OS was 35.1 months (95%CI: 27.93-NR) in the toripalimab arm, with no significant difference in all-cause death (HR: 1.11, 95% CI: 0.66-1.84) for the two arms. The median sums of the patients' actual infusion doses were 3672 mg and 1054.5 MIU in the toripalimab arm and HDI arm, respectively. The incidence of treatment-emergent adverse events with a grade ≥ 3 was much higher in the HDI arm than in the toripalimab arm (87.5% vs. 27.4%). CONCLUSION Toripalimab showed a similar RFS and a more favorable safety profile than HDI, both better than historical data, suggesting that toripalimab might be the better treatment option. However, additional translational studies and better treatment regimens are still warranted to improve the clinical outcome of MM.

Abstract
Objective: To understand the clinical characteristics of children with SARS-CoV-2 Omicron infection imported from Hong Kong Special Administrative Region. Methods: This retrospective study was conducted to collect the data including clinical manifestations, outcomes and vaccination of 107 children with SARS-CoV-2 Omicron infection imported from Hong Kong Special Administrative Region to be admitted to the designated referral hospital in Shanghai from February to March 2022. According to the occurrence of clinical symptoms, the cases were divided into asymptomatic group and symptomatic group. According to the age of diagnosis, the cases were divided into <3 years group, 3-<6 years group and 6-<18 years group, and the clinical manifestations in different age group were analyzed with t-test and Mann-Whitney rank-sum test. Besides, to analyze the effectiveness of vaccination against SARS-CoV-2 Omicron infection in different age group, the cases aged 3-<18 years were also subdivided into unvaccinated group, 1-dose group and 2-dose group, and the relative risk (RR) was used to demonstrate the effectiveness. Results: Among the 107 cases, 66 were male and 41 were female, with infection age of 10 (5, 14) years. There were 29 cases in the asymptomatic group, and 78 cases in the symptomatic group, and no significant difference in the age of infection was observed between the 2 groups (11 (6, 14) vs. 10 (5, 14) years, Z=0.49, P>0.05). And there were no severe cases in symptomatic group. The length of hospitalization was (18±6) days, and was longer in symptomatic group than that in asymptomatic group ((19±6) vs. (16±7) d, t=0.17, P=0.030). Eight-two cases (76.6%) had a history of epidemiological exposure and, among whom, 81 cases (75.7%) were associated with household transmission. Among symptomatic group, 57 cases (73.1%) had fever and 20 cases (25.6%) had cough. Of the 74 cases undergoing chest CT examination, 17 cases (23.0%) showed mild abnormalities. Of the 83 cases who received the lab tests, 23 cases (27.7%) had white blood cell counts<4×109/L, 3 cases (3.6%) had C-reaction protein >8.0 mg/L, and 6 cases (7.2%) had slightly elevated aspartate transaminase and alanine aminotransferase. Among the 92 children aged 3-<18 years, 31 cases were unvaccinated, 34 cases received 1 dose, and 27 cases received 2 doses. The interval between the last vaccination and infection was 2.2 (0.6, 6.0) months; the interval between the last vaccination and infection in the 2-dose group was longer than that in 1-dose group (6.0 (4.5, 7.3) vs. 0.7 (0.3,2.0) months, Z=3.59, P<0.001).The risk of symptomatic infection was reduced by 45% (RR=0.55, 95% CI 0.35-0.87) with two-dose vaccination compared to non-vaccination in cases aged 3-<18 years. All these cases recovered completely. Conclusions: Children infected with SARS-CoV-2 Omicron are usually mild or asymptomatic. Household transmission is the main pattern of infection with SARS-CoV-2 Omicron in children. Two-dose SARS-CoV-2 vaccination in children aged 3-<18 years can provide partial protection against disease caused by SARS-CoV-2 Omicron.

Abstract
BACKGROUND AND OBJECTIVE Individuals with Alzheimer disease and dementia experience cognitive decline and reduction in physical capabilities. Engaging in cognitive challenges and physical exercises is effective in reducing age-related cognitive and physical decline. It is believed that physical activity in the context of cognitive challenges might enhance the process of neurogenesis in the adult brain, but how effective are such interventions? Is there enough evidence to support that dual-task training is more effective than cognitive or physical training alone? To what extent can such training improve cognitive and physical functions in patients at various stages of cognitive decline? METHODOLOGY This systematic review with meta-analysis summarizes the emerging evidence of dual-task training for enhancing cognitive and physical functions in older individuals with cognitive impairment, dementia or Alzheimer's disease. A systematic search was carried out in MEDLINE, PubMed, EMBASE, and Cochrane Library with the following search terms: randomized control trials, dual-task training, SCD, MCI, dementia, and Alzheimer's disease. RESULTS A total of 21 studies with 2,221 participants were identified. The results of dual-task tanning intervention are summarized as change in global cognitive function; SMD = 0.24, (P= 0.002), memory; SMD = 0.28, (P = 0.000), executive function; SMD = 0.35, (P = 0.000), attention; SMD = -0.19, (P = 0.1), gait speed; SMD = 0.26, (P = 0.007), dual-task cost; SMD 0.56, (P = 0.000), and balance; SMD 0.36, (P = 0.004). CONCLUSION Primary analysis showed a small-to-medium positive effect of dual-task training interventions on cognitive functions and medium-to-large positive effect on gait functions and balance.

Abstract
Objective: To evaluate the effect of trifoliate flap design of radial forearm flap in reconstruction of defects after mouth floor cancer resection. Methods: From June 2016 to December 2019, 12 patients with defect after resection of mouth floor cancer were treated with trifoliate flap design of radial forearm flap. All of these patients were T2 stage, included 9 well-differentiated squamous cell carcinoma (SCC) and 3 moderate differentiated SCC. The defect size ranged from 8.0 cm×6.0 cm to 5.0 cm×4.5 cm after resection of tumor and neck dissection. All defects were repaired with trifoliate flap design of radial forearm flap. The flap size ranged from 8.0 cm×2.0 cm to 4.0 cm×1.5 cm, the donor site was sutured directly on Z plasty. Results: All flaps completely survived well. Both the wound and the donor site were stage Ⅰ healing. With the average follow-up of 38.6 months, the swallowing and speech function were satisfactory. Conclusions: Trifoliate flap design of radial forearm flap can effectively repair the postoperative defect of mouth floor cancer, and the donor site can be directly sutured on Z plasty. This technique can avoid forearm scar caused by skin grafting and the formation of the second donor site.

Abstract
Defect engineering with the active control of defect states brings remarkable enhancement on surface-enhanced Raman scattering (SERS) by magnifying semiconductor-molecule interaction. Such light-trapping architectures can increase the light path length, which promotes photon-analytes interactions and further improves the SERS sensitivity. However, by far the reported semiconductor SERS-active substrates based on these strategies are often nonuniform and commonly in the form of isolated laminates or random clusters, which limit their reliability and stability for practical applications. Herein, we develop self-grown single-crystalline "V-shape" SnSe2-x (SnSe1.5, SnSe1.75, SnSe2) nanoflake arrays (SnSe2-x NFAs) with controlled selenium vacancies over large-area (10 cm × 10 cm) for ultrahigh-sensitivity SERS. First-principles density functional theory (DFT) is used to calculate the band gap and the electronic density of states (DOS). Based on the Herzberg-Teller theory regarding the vibronic coupling, the results of theoretical calculation reveal that the downshift of band edge and high DOS of SnSe1.75 can effectively enhance the vibronic coupling within the SnSe1.75-R6G system, which in turn enhances the photoinduced charge transfer resonance and contributes to the SERS activity with a remarkable enhancement factor of 1.68 × 107. Furthermore, we propose and demonstrate ultrasensitive (10-15 M for R6G), uniform, and reliable SERS substrates by forming SnSe1.75 NFAs/Au heterostructures via a facile Au evaporation process. We attribute the superior performance of our SnSe1.75 NFAs/Au heterostructures to the following reasons: (1) selenium vacancies and (2) synergistic effect of the near and far fields. In addition, we successfully build a detection platform to achieve rapid (∼15 min for the whole process), antibody-free, in situ, and reliable early malaria detection (100% detection rate for 10 samples with 160 points) in whole blood, and molecular hemozoin (<100/mL) can be detected. Our approach not only provides an efficient technique to obtain large-area, uniform, and reliable SERS-active substrates but also offers a substantial impact on addressing practical issues in many application scenarios such as the detection of insect-borne infectious diseases.

Abstract
Objective: To compare the efficacy and safety of venetoclax (VEN) combined with azacitidine (AZA) versus CAG regimen combined with decitabine (DAC) in elderly patients with relapsed acute myeloid leukemia (AML). Methods: From January 2018 to August 2020, the clinical data of forty-five elderly patients with relapse AML at the First Affiliated Hospital of Soochow University were retrospectively analyzed, including 31 males and 14 females. The median age was 66 (60-80) years old. Eighteen patients were administrated with VEN and AZA, while the other 27 were in CAG with DAC. The complete remission (CR) rate, partial remission (PR) rate, total remission rate (ORR), adverse events and overall survival (OS) were compared between the two groups. Results: At the end of the treatment, the ORR in VEN with AZA group was 77.8% (14/18); including 11 CR and 3 PR. In CAG with DAC group, the ORR was 37.0% (10/27); including 8 CR and 2 PR (P=0.007). Subgroup analysis suggested that VEN with AZA had a higher ORR in patients stratified as intermediate and poor-risk (P=0.013) or with DNA methylation mutations (P=0.007). Main adverse events in both groups were bone marrow suppression, infections, nausea and vomiting, anorexia and fatigue. Grade Ⅲ-Ⅳ cytopenia developed in lower incidence of VEN with AZA group, such as leukopenia (66.7% vs. 100%, P=0.002), anemia (50.0% vs. 92.6%, P=0.002), thrombocytopenia (72.2% vs. 96.3%, P=0.031) and neutropenia (61.1% vs. 92.6%, P=0.014). In addition, less grade Ⅲ-Ⅳ infections occurred in VEN with AZA group (66.7% vs. 33.3%, P=0.028), as well as grade Ⅲ-Ⅳ gastrointestinal events (40.7% vs. 11.1%, P=0.032), grade Ⅲ-Ⅳ fatigue (55.6% vs.11.1%, P=0.003) compared with CAG with DAC group. The 1-year OS in VEN with AZA group versus CAG with DAC group was 42.9% and 31.6% respectively (P=0.150). Conclusion: VEN combined with AZA proves favorable efficacy and tolerablity in elderly patients with relapsed AML.

Abstract
Objective: To explore the differences of alignment and position of prosthesis between portable accelerometer-based navigation device (PAD) and conventional instrumentation (CI) in total knee arthroplasty (TKA) with valgus deformity. Methods: Patients with knee osteoarthritis and valgus deformity who underwent primary TKA in Peking University Third Hospital from January 2017 to December 2020 were enrolled in this retrospective study and were divided into PAD group and CI group according to the surgical instruments. Five male patients and 44 female patients were included with a mean age of (67.2±7.0) years. The differences in preoperative general data, preoperative and postoperative alignment between the two groups were studied. Results: A total of 49 patients (25 patients in the PAD group and 24 in the CI group) were enrolled in this study. There were no statistically significant differences in gender, age, height, weight, body mass index, surgical side, preoperative hip-knee-ankle (HKA) angle, preoperative HKA angle deviation, Keblish classification and Ranawat classification between the two groups (all P>0.05). There was no significant difference in the accuracy of postoperative HKA angle (2.0°±1.4° vs 3.0°±2.2°, P=0.082), coronal femoral component angle (CFCA) (1.5°±1.2° vs 2.1°±1.6°, P=0.144) and coronal tibial component angle (CTCA) (1.2°±0.8° vs 1.3°±1.0°, P=0.695) between the two groups; but the standard deviation of the above-mentioned three indices in PAD group were all smaller than those in CI group. The rate of outliers of postoperative HKA angle of the PAD group was smaller than that in the CI group (P<0.05), but there was no significant difference in the rate of outliers of CFCA and CTCA between the two groups (both P>0.05). Conclusion: TKA assisted by PAD can provide good alignment and prosthesis position in patients with valgus deformity, and it is superior to TKA with CI in terms of precision and rate of outliers of postoperative overall alignment of lower extremity.

Abstract
Objective: To assess the improvement of the robotic-assisted total hip arthroplasty (rTHA) regarding the acetabular cup positioning and the leg length restoration. Methods: Clinical data of 246 patients undergoing primary unilateral THA from September 2019 to June 2021 in Peking University Third Hospital were retrospectively reviewed, including patients treated with rTHA (n=113) and conventional THA (cTHA) (n=133). Thirty-seven male patients along with 76 females were enrolled into the rTHA group with a mean age of (62±9) years. In comparison, the average age of cTHA group was (60±12) years with 59 males and 74 females. The postoperative inclination and anteversion of the acetabular cup and the rate of acetabular cup within the Lewinnek and Callanan "safe zone" were documented and analyzed. For the patient with normal or surgically restored contralateral hip, the leg length discrepancy was also measured and compared between the two groups. Results: The overall mean postoperative inclination and anteversion was 39.0°±5.5° and 14.1°±5.1°, respectively. No statistically significant difference was found between the rTHA and cTHA group regarding postoperative inclination (39.3°±2.9° vs 38.7°±7.0°, P=0.383) and anteversion (13.4°±4.3° vs 14.7°±5.6°, P=0.054). In rTHA group, 97.3%(110/113) of the cups were implanted within the Lewinnek"safe zone"(75.9%(101/133) in cTHA group) and 94.7%(107/113) were within the Callanan"safe zone"(66.2%(88/133) in cTHA group), and those were both higher in rTHA group (both P<0.01). There was no significant difference in postoperative leg length discrepancy between the two groups (P=0.445). Meanwhile, 29(23.0%) cases of cTHA group had leg length discrepancy more than 5 mm, and it was 9.7%(9/93) in rTHA group. Conclusion: It indicated the benefit of rTHA in acetabular cup positioning as well as the leg length restoration.

Abstract
Artificial joint arthroplasty, such as total hip and total knee arthroplasty, is one of the most successful procedures in orthopedics. The quality of life of these patients can be improved significantly through relieving pain, correcting the deformity and improving joint function. Although hip and knee arthroplasty currently are routine surgeries for patients with late stage joint diseases, post-operative complications like leg length discrepancy, dislocation or instability, limp and uncertain reason pain are still common. The position of the implants plays important roles in all these complications. Robotic assisted joint arthroplasty can not only provide 3D pre-operative visual planning, but also can assist to fulfill the pre-operation plan perfectly. But the current joint arthroplasty robots cannot carry out automatic personalized pre-operation planning, and also have the shortcomings of low efficiency and high cost etc. However, based on their current performance and with the help of artificial intelligence and better algorithm, we believe that joint arthroplasty will be more and more precisive, intelligent and minimally invasive, which is an inevitable trend in the development of joint surgery.

Abstract
Objective: To explore the differences of alignment and operative time between computer assisted surgery (CAS) and personal specific instrumentation (PSI) in total knee arthroplasty (TKA). Methods: Patients with knee osteoarthritis who underwent unilateral primary TKA in Peking University Third Hospital from June 2019 to April 2021 were enrolled in this prospective study and were randomly divided into CAS group and PSI group with random number table. The differences in preoperative general data, operative time, preoperative and postoperative alignment between the two groups were studied. Results: A total of 80 patients were enrolled in this study, including 40 patients in the CAS group with an average age of (68±6) years (male/female, 6/34 cases) and 40 patients in the PSI group with an average age of (69±6) years (male/female, 5/35 cases). There was no significant differences in gender, age, height, weight, body mass index, surgical side, preoperative hip-knee-ankle (HKA) angle, and preoperative HKA angle deviation between the two groups (all P>0.05). The accuracy of sagittal femoral component angle (sFCA) (1.7°±1.2° vs 2.5°±1.4°, P<0.05) and sagittal tibial component angle (sTCA) (1.2°±0.9° vs 2.3°±1.8°, P<0.01) of the CAS group were both smaller than those in the PSI group, but there was no significant difference in the accuracy of postoperative HKA angle, mechanical lateral distal femoral angle (mLDFA) and mechanical medial proximal tibia angle (mMPTA) between the two groups (all P>0.05). The precision of postoperative HKA angle and sTCA of the CAS group were both smaller than those in the PSI group (2.0°±1.0° vs 2.6°±1.7°, 1.2°±0.9° vs 2.3°±1.8°, both P<0.01), but there was no significant differences in the precision of mLDFA, mMPTA and sFCA between the two groups (all P>0.05). The rate of outliers of postoperative HKA angle (10.0% vs 27.5%, P<0.05), sFCA(5.0% vs 20.0%, P<0.05) and sTCA (2.5% vs 22.5%, P<0.01) of the CAS group were all smaller than those in the PSI group, but there was no significant difference in the rate of outliers of mLDFA and mMPTA between the two groups (both P>0.05). CAS group had significantly longer surgical time than the PSI group ((81±12) min vs (52±8) min, P<0.01). Conclusions: CAS is better than PSI in overall coronal alignment and sagittal position of the prosthesis after TKA. However, CAS requires a longer operation time.

Abstract
AIMS To evaluate the associations of morning serum cortisol levels with obesity defined by different indices in Chinese rural populations. MATERIALS AND METHODS A cross-sectional study was performed including 6198 participants (2566 males and 3632 females). Serum cortisol was collected in morning and quantified by liquid chromatography-tandem mass spectrometry. Obesity was defined by body mass index (BMI), body fat percentage (BFP), waist-to-height ratio (WHtR), waist circumference (WC), visceral fat index (VFI) and waist-to-hip ratio (WHR). Both multivariable liner regression, logistic regression and restrictive cubic splines models were used to estimate the gender-specific relationships between cortisol levels and obesity defined by different indices, respectively. RESULTS After adjusting for potential confounders, serum cortisol was negatively associated with different obesity measures, except obese females defined by BFP (for instance, overall obesity defined by BMI, Quartile 4 vs. Quartile 1, odds ratio (OR) = 0.25, 95% confidence interval (CI):0.15, 0.41 in males, and OR = 0.58, 95% CI: 0.42,0.80 in females, central obesity defined by WC, OR = 0.52, 95% CI:0.39,0.69 in males and OR = 0.63, 95% CI:0.51,0.77 in females). Similarly, restrictive cubic splines showed the nonlinear relationship between high levels of cortisol and different obesity indices. Furthermore, ROC curve analysis indicated that cortisol could improve the discrimination of model with common biomarkers. CONCLUSION Morning serum cortisol were negatively related to obesity defined by different indices in Chinese rural populations. In addition, cortisol could be as a biomarker for prediction of obesity in males.

Abstract
OBJECTIVES To assess the effectiveness of secukinumab in patients with axSpA treated in routine clinical settings in 5 European countries. METHODS Retrospective analysis of a cross-sectional survey to assess real-world effectiveness of secukinumab in the management of axSpA and rheumatologist satisfaction with treatment in France, Germany, Italy, Spain and the UK from March to December 2018. Outcomes collected included patient demographics, clinical characteristics and rheumatologist- and patient-reported satisfaction with secukinumab treatment. RESULTS Five hundred thirty-five patients receiving secukinumab for more than 4 months were assessed, 359 of whom were diagnosed with AS and 178 with nr-axSpA. Rheumatologist assessment of disease status at treatment initiation indicated that 39 (7.3%) had stable/improving disease. Secukinumab treatment for 4 months or longer resulted in 515 (95.9%) patients judged as stable/improving. Treatment was associated with benefits from initiation to assessment in terms of BASDAI (6.2 vs 2.8), 44-joint count score (9.7 vs 6.6), rheumatologist global VAS score (56.9 vs 23.0) and patient global VAS scores (64.4 vs 25.5). These benefits for key clinical outcomes were sustained for periods of 12 months or longer. Patient-reported outcomes on health status using EQ-5D, global functioning using the ASAS health index and overall work impairment via WPAI were sustained over the treatment period, while patient and rheumatologist satisfaction with secukinumab treatment remained very high at 80.2 and 91.2%, respectively. CONCLUSION Consistent benefits across multiple clinical and patient-reported outcomes were seen with secukinumab treatment in patients with AS and nr-axSpA treated in routine clinical settings across five European countries. Key Points • In routine clinical settings across five European countries, secukinumab treatment resulted in improvements in a wide range of clinical outcomes including physician-reported disease severity, disease status, pain, BASDAI, 44-joint count score and global VAS scores. • Key clinical and patient reported outcomes were sustained for a 12-month period or longer with secukinumab treatment. • Rheumatologist- and patient-reported treatment satisfaction was high with secukinumab.

Abstract
OBJECTIVE To explore the role of human short stature homeobox 2 (SHOX2) in regulating the migration, invasion and stemness of human bladder cancer cells. METHODS We analyzed SHOX2 gene expression in bladder cancer and adjacent tissues based on TCGA database. Univariate survival analysis of SHOX2 gene expression in TCGA-BLCA data was performed using GEPIA. The probable function of SHOX2 was predicted using GSEA. Human bladder cancer T24 cell models of SHOX2 knockdown or overexpression were assessed for changes in migration and invasion abilities using wound healing assay and Transwell assay, and their cancer stem cell-like characteristics were evaluated using tumorsphere formation assay and colony formation assay. Western blotting was used to detect the expressions of epithelial mesenchymal transition (EMT) markers Ecadherin and vimentin and the TGF-β signaling network component TβR-I in the cells. RESULTS SHOX2 expression was significantly higher in bladder cancer tissues than in the adjacent tissues (P < 0.05), especially in paired tissue specimens (P < 0.01), and was negatively correlated with the overall survival of the patients (P < 0.05). SHOX2 gene expression was correlated positively with EMT-related (P < 0.05) and stemness-related gene signatures (P < 0.01). In T24 cells, SHOX2 knockdown significantly suppressed cell migration and invasion, which was significantly enhanced by SHOX2 overexpression (P < 0.01). The cancer stem cell-like characteristics of T24 cells was repressed by SHOX2 knockdown but significantly enhanced by SHOX2 overexpression (P < 0.01). SHOX2 knockdown induced morphological changes of the cells into epithelioid cells, whereas SHOX2 overexpression induced a mesenchymal morphology of the cells. SHOX2 knockdown increased E-cadherin expression and decreased vimentin and TβR-I expression, while SHOX2 overexpression increased the expressions of vimentin and TβR-I in the cells. CONCLUSION SHOX2 promotes the migration, invasion and stemness of human bladder cancer cells possibly by regulating EMT via the TGF-β signaling pathway.

Abstract
OBJECTIVE To explore the effect of sleeve gastrectomy on type 2 diabetes mellitus (T2DM) in regulating ghrelin and intestinal lesions. MATERIALS AND METHODS Specific pathogen free (SPF) Wistar rats were injected with streptozotocin (STZ) after giving a high-sugar and high-fat diet, to establish a T2DM rat model. The rats were randomly divided into a sleeve gastric excision group, a non-surgical group and a fake surgical group, with 10 rats in each group. The weight, blood glucose, glucose tolerance and ghrelin hormone of rats were compared. The feces of rats in each group at the 8th week after surgery were collected, to extract the total bacterial deoxyribonucleic acid (DNA). The bacterial 16S universal primer was used to expand the 16SrRNA V46 conserved region. The total Polymerase Chain Reaction (PCR) products were sequenced by PE101-bp to classify the gene and genera. RESULTS The weight of the rats after sleeve gastrectomy significantly decreased (p <0.05). The area under the blood glucose curve and the area under the insulin curve were significantly smaller than those in the non-surgical group and the fake surgical group (p <0.05). Compared with the sleeve gastric excision group, the abundance of Phylum Firmicutes was higher, that of Bacteroidetes was lower. Compared with the sleeve gastric excision group, there were more genera in the fake surgical group and the non-surgical group. The genera with higher abundance in the three groups were Lactobacillus and Bacteroidetes. Compared with the sleeve gastric excision group, the fake surgical group and the non-surgical group had higher abundance of Phylum Firmicutes (p <0.05) and lower abundance of Bacteroidetes (p <0.05). CONCLUSIONS To sum up, sleeve gastrectomy can reduce the weight of rats in T2DM rat model, lower blood glucose levels of rats in the model and improve insulin resistance levels. The related mechanism may be related to the upregulation of ghrelin and intestinal flora.

Abstract
Abiotic stresses are major environmental factors inhibiting plant growth and development. AITRs (ABA-induced transcription repressors) are a novel family of transcription factors regulating ABA (abscisic acid) signalling and plant responses to abiotic stresses in Arabidopsis. However, the composition and evolution history of AITRs and their roles in the cotton genus are largely unknown. A total of 12 putative AITRs genes were identified in cultivated tetraploid cotton, Gossypium hirsutum. Phylogenetic analysis of GhAITRs in these tetraploid cottons and their closely related species implicate ancient genome-wide duplication occurring after speciation of Gossypium, and Theobroma could generate duplicates of GhAITRs. Duplicated GhAITRs were stably inherited following diploid speciation and further allotetraploidy in Gossypium. Homologous GhAITRs shared common expression patterns in response to ABA, drought and salinity treatments, and drought tolerance induced in transgenic Arabidopsis plants expressing GhAITR-A1. Together, our findings reveal that duplicates in the GhAITRs gene family were achieved by whole genome duplication rather than three individual duplication events, and that GhAITRs function as transcription repressors and are involved in the regulation of plant responses to ABA and drought stress. These results provide insights towards the improvement of abiotic stress tolerance in cotton using GhAITRs.

Abstract
Oxidative stress is an important factor affecting retinal ganglion cell (RGC) apoptosis. RGC apoptosis is the main pathophysiological feature of visual impairment as a result of glaucoma. Recently, it has been found that long noncoding RNA (lncRNA) and microRNAs are involved in RGC
apoptosis. Here, the function of lncRNA maternally expressed gene 3 (MEG3) and miR-30b in H2 O2-induced RGC proliferation, apoptosis, and oxidative stress was investigated. The expression levels of MEG3 and miR-30b were detected by RT-PCR; the effects of MEG3 and miR-30b
on the proliferation and apoptosis of RGCs were observed by flow cytometry; the levels of apoptosis-related proteins and AKT/PI3K signal pathway proteins were detected by protein immunoassay; and the regulation of miR-34a by pvt1 was verified by in vivo and in vitro experiments.
The expression of MEG3 and miR-30b increased and decreased significantly in RGCs treated by H2O2. MEG3 expression decreased, apoptosis level-related proteins decreased, the apoptosis rate reduced, and the activity of MDA and SOD decreased. When the expression of miR-34a
was inhibited, the proliferation rate of RGCs increased, the apoptosis rate decreased, and the level of apoptosis-related proteins decreased, which reversed MEG3’s effect on RGC apoptosis and proliferation. Furthermore, pvt1 could bind the miR-30b promoter and regulate it with in
vitro expression and in vivo expression. Besides, we found that miR-30b can regulate the AKT/PI3K signaling pathway and participate in cell apoptosis and hyperplasia in stress response. LncRNA MEG3 targets miR-30b and regulates the AKT/PI3K signaling pathway on H2 O2-induced
cell apoptosis, hyperplasia, and oxidative stress of RGCs.

Abstract
In transmission electron microscope (TEM), both the amplitude and phase of electron beam change when electrons traverse a specimen. The amplitude is easily obtained by the square root of the intensity of a TEM image, while the phase affects defocused images. In order to obtain the phase map and verify the theoretical model of the interaction between electron beam and specimen, a lot of simulations have been performed by researchers. In this work, we have simulated defocus images of a SiC nanowire in TEM with the method of electron optics. Mean inner potential and charge distribution on the nanowire have been considered in the simulation. Besides, due to electron scattering coherence loss of the electron beam has been introduced. A dynamic process with Bayesian optimization was used in the simulation. With the infocus image as input and by adjusting fitting parameters the defocus image is determined with a reasonable charge distribution. The calculated defocus images are in a good agreement with the experimental ones. Here, we present a complete solution and verification method for solving nanoscale charge distribution in TEM.

Abstract
Objective: To describe the clinical features of liver involvement in children and adolescent with 2019-nCoV infection. Methods: The clinical data of 77 hospitalized cases admitted to the Children's Hospital of Fudan University were collected from January 19 to November 28, 2020. The characteristics and risk factors of abnormal liver chemistries in children with laboratory-confirmed 2019-nCoV infection were analyzed. Results: Of the 77 cases, 44 were male (57.1%) and 33 were female (42.9%), with a median age of 10 years. 27(35.1%) were asymptomatic, 28(36.4%) had mild illness, 22(28.6%)had non-severe pneumonia. Hydroxychloroquine was used in 7 cases. Of the 75 children without underlying diseases, alanine aminotransferase was elevated in 1 case (1.5%, during hydroxychloroquine therapy), aspartate aminotransferase was elevated in 7 cases (10.3%), alkaline phosphatase was elevated in 7 cases (28%), and total bilirubin, direct bilirubin, albumin, international normalized ratio were in normal range. There was no statistical difference between the pneumonia group and the non-pneumonia group in term of liver chemistries (P > 0.05), same as between the elevated erythrocyte sedimentation rate group and the normal group. There was no aggravation of liver injury in the child with biliary atresia. The child with epilepsy showed no abnormal liver chemistries after infection. Conclusion: Children with 2019-nCoV infection had mild clinical symptoms with few cases of liver injury. The abnormal liver chemistries in children with COVID-19 infection may be related to the underlying disease and the use of antiviral drugs.

Abstract
This roadmap on Nanotechnology for Catalysis and Solar Energy Conversion focuses on the application of nanotechnology in addressing the current challenges of energy conversion: 'high efficiency, stability, safety, and the potential for low-cost/scalable manufacturing' to quote from the contributed article by Nathan Lewis. This roadmap focuses on solar-to-fuel conversion, solar water splitting, solar photovoltaics and bio-catalysis. It includes dye-sensitized solar cells (DSSCs), perovskite solar cells, and organic photovoltaics. Smart engineering of colloidal quantum materials and nanostructured electrodes will improve solar-to-fuel conversion efficiency, as described in the articles by Waiskopf and Banin and Meyer. Semiconductor nanoparticles will also improve solar energy conversion efficiency, as discussed by Boschloo et al in their article on DSSCs. Perovskite solar cells have advanced rapidly in recent years, including new ideas on 2D and 3D hybrid halide perovskites, as described by Spanopoulos et al 'Next generation' solar cells using multiple exciton generation (MEG) from hot carriers, described in the article by Nozik and Beard, could lead to remarkable improvement in photovoltaic efficiency by using quantization effects in semiconductor nanostructures (quantum dots, wires or wells). These challenges will not be met without simultaneous improvement in nanoscale characterization methods. Terahertz spectroscopy, discussed in the article by Milot et al is one example of a method that is overcoming the difficulties associated with nanoscale materials characterization by avoiding electrical contacts to nanoparticles, allowing characterization during device operation, and enabling characterization of a single nanoparticle. Besides experimental advances, computational science is also meeting the challenges of nanomaterials synthesis. The article by Kohlstedt and Schatz discusses the computational frameworks being used to predict structure-property relationships in materials and devices, including machine learning methods, with an emphasis on organic photovoltaics. The contribution by Megarity and Armstrong presents the 'electrochemical leaf' for improvements in electrochemistry and beyond. In addition, biohybrid approaches can take advantage of efficient and specific enzyme catalysts. These articles present the nanoscience and technology at the forefront of renewable energy development that will have significant benefits to society.

Abstract
OBJECTIVE The purpose of this study was to uncover the potential role of non-coding RNA activated by DNA damage (lncRNA NORAD) in the disease progression of diabetic cardiomyopathy (DCM) and the underlying mechanism. MATERIALS AND METHODS Cell viability, 5-Ethynyl-2'-deoxyuridine (EdU)-positive ratio and apoptotic rate in human cardiomyocyte cell line AC16 undergoing treatment of normal-level (NG) or high-level glucose (HG) were assessed at first. NORAD level in HG-induced AC16 cells at different time points was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Subsequently, cell viability, EdU-positive ratio, and apoptotic rate in HG-induced AC16 cells overexpressing NORAD were evaluated. Next, subcellular distribution of NORAD was examined, and Dual-Luciferase reporter gene assay was performed to clarify the interaction among NORAD, miRNA-150-5p, and ZEB1. At last, rescue experiments were conducted to clarify the role of NORAD/miRNA-150-5p/ZEB1 axis in influencing the proliferation and apoptosis in HG-induced AC16 cells. RESULTS Results revealed that HG treatment suppressed the proliferative ability and stimulated apoptosis in AC16 cells. Besides, NORAD was time-dependently downregulated in HG-induced AC16 cells, and it was mainly distributed in cytoplasm. In addition, the overexpression of NORAD enhanced proliferative ability, attenuated apoptosis, and increased Bcl-2/Bax ratio in HG-induced AC16 cells. Finally, NORAD/miRNA-150-5p/ZEB1 axis was verified to protect the malignant progression of DCM. CONCLUSIONS NORAD is upregulated under high-level glucose treatment. Overexpression of NORAD protects DCM development via miRNA-150-5p/ZEB1 axis.

Abstract
Objective: To compare the perioperative blood loss in patients undergoing a total knee arthroplasty (TKA) across three different techniques: computer-assisted navigation surgery (CAS), patient specific instrumentation (PSI) and conventional instrumentation (CI). Methods: Ninety consecutive patients with severe knee osteoarthritis who underwent unilateral primary TKA in Peking University Third Hospital Orthopedics Department from January 2018 to December 2018 were enrolled in this prospective study. The patients were randomly divided into three groups (30 case in each group): CAS-TKA group, PSI-TKA group and CI-TKA group. The study measured intraoperative blood loss, total blood loss, hidden blood loss, decreases of hemoglobin and hematocrit, and the post-TKA blood transfusions in the three groups. One-way ANOVA was used to detect the differences among the cohorts, and LSD was used for the post-hoc test. Results: The overall intraoperative blood loss of all patients was 6 ml (5~8 ml). The mean total blood loss and hidden blood loss in CAS-TKA group, PSI-TKA group and CI-TKA group was (1 147.0±301.8) and (1 140.1±301.9)ml, (1 044.3±454.1) and (1 038.5±454.0)ml, (1 154.0±483.6) and (1 145.3±482.7)ml, respectively; there was no significant differences among the three groups (F=0.639, 0.616, both P>0.05). There were no patients who received allogeneic blood transfusion. There were no significant differences in decrease of hemoglobin and hematocrit among the three groups neither (both P>0.05). Conclusions: Compared with conventional TKA, CAS and PSI does not increase the total blood loss of TKA. However, they both demonstrate a potential benefit in reducing blood loss of TKA.

Abstract
Objective: To investigate the effects of thoracoscopy-guided thoracic paravertebral block for analgesia after single-port video-assisted pulmonary lobectomy. Methods: From December 2019 to April 2020, 60 patients receiving single-port video-assisted pulmonary lobectomy at Ningbo Medical Center Lihuili Hospital were selected. The patients were randomly and equally divided into control group and paravertebral block group using a random number table. Patients of paravertebral block group were injected into the thoracic 4-5 intercostal, paravertebral 1 cm using 0.375% ropivacaine (20 ml) with thoracoscopy-guided at the end of surgery, while patients of control group were given patient controlled intravenous analgesia (PCIA). Postoperative visual analogue scale (VAS) and Ramsay sedation scale were recorded at 6, 12, 24, 36, 48 h after the surgery. The incidence of postoperative adverse reactions, additional dose and times of pethidine, the time to resume eating, the rate of postoperative active cough, the first time to get out of bed after surgery and postoperative hospital stay of two groups' patients were recorded. t test and chisquare test were used for statistical analysis. Results: The VAS score of paravertebral block group were lower than those of control group at all time points (all P<0.05). The Ramsay sedation scale of paravertebral block group were higher than those of control group at all time points (all P<0.05). The additional dose and times of pethidine of paravertebral block group were (8.2±2.3) mg and (0.2±0.1) time, which were lower than (87.8±15.3) mg and (1.8±0.3) time of control group, the differences were statistically significant (t=28.91, 34.37, all P<0.05). Incidence of nausea, vomiting and pruritus of paravertebral block group were 10.0%, 6.7% and 0, which were lower than 40.0%, 30.0% and 13.3% of control group, the differences were statistically significant (χ(2)=7.20, 5.45, 4.29, all P<0.05). The rate of postoperative active cough of paravertebral block group was 33.3%, which was higher than 10.0% of control group, the difference was statistically significant (χ(2)=4.81, P<0.05). The time to resume eating, the first time to get out of bed after surgery and postoperative hospital stay were (6.5±0.4) h, (20.9±3.1) h and (4.6±1.0) d, which were lower than (8.5±0.7) h, (28.6±4.8) h and (6.1±1.3) d of control group, the differences were statistically significant (t=13.47, 7.39, 4.19, all P<0.05). Conclusion: Thoracic paravertebral block under thoracoscopy-guided can effectively reduce the postoperative pain of single-port thoracoscopic lobectomy, with fewer adverse reactions, and is beneficial to postoperative recovery.

Abstract
In Europe, three widespread extreme summer drought and heat (DH) events have occurred in 2003, 2010 and 2018. These events were comparable in magnitude but varied in their geographical distribution and biomes affected. In this study, we perform a comparative analysis of the impact of the DH events on ecosystem CO2 fluxes over Europe based on an ensemble of 11 dynamic global vegetation models (DGVMs), and the observation-based FLUXCOM product. We find that all DH events were associated with decreases in net ecosystem productivity (NEP), but the gross summer flux anomalies differ between DGVMs and FLUXCOM. At the annual scale, FLUXCOM and DGVMs indicate close to neutral or above-average land CO2 uptake in DH2003 and DH2018, due to increased productivity in spring and reduced respiration in autumn and winter compensating for less photosynthetic uptake in summer. Most DGVMs estimate lower gross primary production (GPP) sensitivity to soil moisture during extreme summers than FLUXCOM. Finally, we show that the different impacts of the DH events at continental-scale GPP are in part related to differences in vegetation composition of the regions affected and to regional compensating or offsetting effects from climate anomalies beyond the DH centres. This article is part of the theme issue 'Impacts of the 2018 severe drought and heatwave in Europe: from site to continental scale'.

Abstract
Phosphate (Pi) deficiency severely restricts plant growth and development, as Pi is an essential macronutrient. Calcium (Ca2+ ) is a ubiquitous second messenger in plants; calcineurin B-like proteins (CBL) and CBL-interacting protein kinases (CIPK) are signalling pathways that act as an important Ca2+ signalling network which integrates plants to fine tune the response to stress; however, whether CIPK are involved in Pi deficiency stress remains largely unknown. In this study, we carried out a reverse genetic strategy to screen T-DNA insertion mutants of CIPK isoforms under Pi deficiency in Arabidopsis thaliana. Then Pi content, transcription of phosphate starvation-induced (PSI) genes, acid phosphatase activity and hydrogen peroxide were determined in the wild-type (WT) and cipk1 mutant, respectively. The phenotype of CIPK1 complementation lines was analysed. The cipk1 mutant had a more sensitive phenotype, with lower root elongation and root length, and decreased Pi content compared with the WT under Pi deficiency. Moreover, CIPK1 mutation caused phosphate starvation-induced (PSI) genes to be significantly induced under Pi deficiency. Histological staining demonstrated that the cipk1 mutant had increased acid phosphatase activity and hydrogen peroxide concentration under Pi deficiency. By using the yeast two-hybrid system, we further demonstrated the interaction between CIPK1 and the WRKY transcription factors, WRKY6 and WRKY42. Overall, we demonstrate that CIPK1 is involved in the Pi deficiency signalling pathway in A. thaliana, revealing the important role of Ca2+ in the Pi nutrition signalling pathway, and potentially providing a theoretical foundation for molecular breeding of crops with better Pi utilization efficiency.

Abstract
OBJECTIVE This study evaluates the efficacy of statin-ezetimibe co-therapy compared to statin monotherapy in reducing cardiovascular and/or cerebrovascular disease (CVD) prevalence in diabetes and non-diabetes patients. PATIENTS AND METHODS Literature search was conducted in electronic databases and study selection was based on pre-determined eligibility criteria. Random-effects metanalyses were performed to examine the risk of CVD incidence between statin-ezetimibe co-therapy and statin monotherapy and subgroups were performed to examine the significance of differences between diabetic and non-diabetic individuals. A pooled analysis of hazard ratios of statin-ezetimibe combination versus statin monotherapy in the prevalence of CVD reported by the individual studies was also performed. RESULTS 8 studies (136893 individuals; 80790 diabetics, 85555 non-diabetics; age 63.5 years [95% confidence interval (CI) 61.2, 65.8]; 61.5% [95% CI 55.2, 67.8] males) were included. Follow-up duration was 45 months [95% CI 27.5, 62.5]. Risk of CVD prevalence was significantly less with ezetimibe-statin than with statin alone in both diabetes (RR 0.69 [95% CI 0.67, 0.73]; p<0.00001) and in non-diabetes (RR 0.68 [95% CI 0.52, 0.90]; p=0.006) subjects (subgroup difference: chi2=0.00; p=0.97). Risk of prevalence of stroke was significantly less with ezetimibe-statin than with statin monotherapy in diabetes (RR 0.74 [95% CI 0.56, 0.98]; p=0.03) but non-significantly less in non-diabetes patients (RR 0.74 [95% CI 0.39, 1.41]; p=0.39) and this sub-group difference was also not statistically significant (chi2=0.00; p=0.99). CONCLUSIONS Statin-ezetimibe co-therapy is found more efficacious than statin monotherapy in reducing the incidence of CVD with no significant difference between diabetic and non-diabetic individuals.

Abstract
Background:Secukinumab has demonstrated significant and sustained reduction of disease activity and improvement in physical functioning and quality of life in PsA pts in RCTs.1Objectives:This study assessed effectiveness of secukinumab in PsA in a real-world setting.Methods:This was a cross-sectional survey of rheumatologists, dermatologists and pts in France, Germany, Italy, Spain, and UK. Data were collected online from June-Dec 2018 via physician-completed patient record forms. Pts receiving any treatment for PsA were included in survey (n=1675). Pts receiving secukinumab >4 months were included in this analysis. Pts reported quality of life, work, and disability measures at their current consultation. Physicians reported patient demographic and disease characteristics, concomitant and previous treatments, and time since diagnosis. Physicians also reported overall, skin and joint disease severity, pain (1-10 scale), BSA psoriasis involvement, global VAS score, PASI score, SJC, and TJC for 2 time points: initiation of treatment and at the time of data collection (current consultation). Data were analysed descriptively. The data analysed here is representative of pts that are currently receiving secukinumab and does not assess pts that have discontinued treatment.Results:572 PsA pts were receiving secukinumab >4 months at their current consultation. Patient mean age was 47.9 yrs, with 43% female, 59% working full time, and a mean BMI of 26.6. On average, pts were diagnosed with PsA 5.6 years before the current consultation, had received secukinumab for 11.0 months, and for 59% of pts secukinumab was their 1st advanced therapy (bDMARDs or tsDMARDs), 24% their 2nd and 16% their 3rd or more. 25% of pts were also receiving a csDMARD concurrently. Pts reported a mean EQ5D utility score of 0.83, mean WPAI overall work impairment of 24.3%, mean HAQ-DI score as 0.6, and mean PsAID12 score as 2.6 at current consultation. Proportion of pts with moderate and severe overall disease severity, and skin and joint severity decreased at current consultation vs at the initiation treatment (Table 1). Between initiation of treatment and current consultation, pts achieved a significant reduction in disease activity scores, pain score, global VAS scores, BSA, PASI score as well as a greater proportion of pts achieving a BSA < 3%, a PASI score < 3 (Table 2).Conclusion:This multinational study demonstrated secukinumab effectiveness in routine care in PsA pts, with significant improvements across all outcomes.References:[1]Mease et al.

Abstract
Background:Patients with psoriatic arthritis (PsA) present with heterogeneous clinical phenotypes, which includes different clinical manifestations such as peripheral arthritis, axial disease, dactylitis, enthesitis, and skin and nail psoriasis. Many drugs for treatment of PsA are available for individualised treatment strategies but robust evidence is available for peripheral arthritis only as primary endpoint of RCTs.Objectives:To evaluate perception of German physicians on the value of current PsA treatments on different clinical PsA manifestations.Methods:In a face-to-face meeting, 8 German physicians (dermatology, rheumatology), specialised in PsA research/patient care, proposed initial scores for the effect size of current PsA drugs on different PsA manifestations based on knowledge of study data and personal experience in use of the drugs. The ability to achieve a consensus of the proposed efficacy scores was explored by applying an online survey among a cohort of PsA experienced physicians. Finally, a second online survey evaluated how a larger group of physicians personally estimate the drug effect sizes on different PsA manifestations.Results:Table 1 summarises the efficacy scores proposed by the initial expert group. In the first online survey 25 treating physicians were invited to participate, 14 (56%) of whom completed the survey. An agreement rate of over 65% of the participants was archived for 49 (68%) of the 72 proposed efficacy scores (Table 1). The consensus was especially high for the group of biological disease-modifying antirheumatic drugs (bDMARDs), except for etanercept and abatacept. However, the second survey (16 (39%) participants out of 41 invited physicians) revealed that the experience with the treatment using abatacept was low (4 / 16 (25%)) or non-existing (3 /16 (18.8%)) and several manifestations could not be estimated (Figure 1). Distribution of answers were broad for etanercept in general and for particular drug-manifestation combinations (e.g. effect of ustekinumab on axial disease).Table 1.Efficacy scores proposed by a PsA expert group and consensus achieved by an online survey among PsA treating physicians Efficacy scores for different drugs and manifestations range from 0 (no effect) to 5 (maximal effect).

Red stars indicate the scores proposed by the initial expert group.Conclusion:Many treatments are available to be used in PsA. The usage of treatment classes seems to depend on experience level and mode of action. Higher agreement on efficacy in specific diseases manifestation was achieved in the class of biologics whereas the opinion on efficacy of csDMARDs in general is divergent. Strategies are needed to guide physicians with lower level of experience in the use of specific drugs to achieve an optimised patient care level using personalized treatment strategies.Disclosure of Interests:Timm Oberwahrenbrock Grant/research support from: BMS, Hannah Tian: None declared, Diamant Thaçi Grant/research support from: Janssen Research & Development, LLC, Klaus Krueger Consultant of: Celgene, Jürgen Wollenhaupt Consultant of: Celgene, Michaela Köhm Grant/research support from: Pfizer, Janssen, BMS, LEO, Consultant of: BMS, Pfizer, Speakers bureau: Pfizer, BMS, Janssen, Novartis, Frank Behrens Grant/research support from: Pfizer, Janssen, Chugai, Celgene, Lilly and Roche, Consultant of: Pfizer, AbbVie, Sanofi, Lilly, Novartis, Genzyme, Boehringer, Janssen, MSD, Celgene, Roche and Chugai

Abstract
In summer 2018, central and northern Europe were stricken by extreme drought and heat (DH2018). The DH2018 differed from previous events in being preceded by extreme spring warming and brightening, but moderate rainfall deficits, yet registering the fastest transition between wet winter conditions and extreme summer drought. Using 11 vegetation models, we show that spring conditions promoted increased vegetation growth, which, in turn, contributed to fast soil moisture depletion, amplifying the summer drought. We find regional asymmetries in summer ecosystem carbon fluxes: increased (reduced) sink in the northern (southern) areas affected by drought. These asymmetries can be explained by distinct legacy effects of spring growth and of water-use efficiency dynamics mediated by vegetation composition, rather than by distinct ecosystem responses to summer heat/drought. The asymmetries in carbon and water exchanges during spring and summer 2018 suggest that future land-management strategies could influence patterns of summer heat waves and droughts under long-term warming.
