Abstract
Objective: To summarize the clinical characteristics of tumour necrosis factor receptor-associated periodic syndrome (TRAPS) in children. Methods: The clinical manifestations, laboratory tests, genetic testing and follow-up of 10 children with TRAPS from May 2011 to May 2021 in 6 hospitals in China were retrospectively analyzed. Results: Among the 10 patients with TRAPS, including 8 boys and 2 girls. The age of onset was 2 (1, 5) years, the age of diagnosis was (8±4) years, and the time from onset to diagnosis was 3 (1, 7) years. A total of 7 types of TNFRSF1A gene variants were detected, including 5 paternal variations, 1 maternal variation and 4 de novo variations. Six children had a family history of related diseases. Clinical manifestations included recurrent fever in 10 cases, rash in 4 cases, abdominal pain in 6 cases, joint involvement in 6 cases, periorbital edema in 1 case, and myalgia in 4 cases. Two patients had hematological system involvement. The erythrocyte sedimentation rate and C-reactive protein were significantly increased in 10 cases. All patients were negative for autoantibodies. In the course of treatment, 5 cases were treated with glucocorticoids, 7 cases with immunosuppressants, and 7 cases with biological agents. Conclusions: TRAPS is clinically characterized by recurrent fever accompanied by joint, gastrointestinal, skin, and muscle involvement. Inflammatory markers are elevated, and autoantibodies are mostly negative. Treatment mainly involves glucocorticoids, immunosuppressants, and biological agents.

Abstract
BACKGROUND Safe and effective vaccines are urgently needed to end the COVID-19 pandemic caused by SARS-CoV-2 infection. We aimed to assess the preliminary safety, tolerability, and immunogenicity of an mRNA vaccine ARCoV, which encodes the SARS-CoV-2 spike protein receptor-binding domain (RBD). METHODS This single centre, double-blind, randomised, placebo-controlled, dose-escalation, phase 1 trial of ARCoV was conducted at Shulan (Hangzhou) hospital in Hangzhou, Zhejiang province, China. Healthy adults aged 18-59 years negative for SARS-CoV-2 infection were enrolled and randomly assigned using block randomisation to receive an intramuscular injection of vaccine or placebo. Vaccine doses were 5 μg, 10 μg, 15 μg, 20 μg, and 25 μg. The first six participants in each block were sentinels and along with the remaining 18 participants, were randomly assigned to groups (5:1). In block 1 sentinels were given the lowest vaccine dose and after a 4-day observation with confirmed safety analyses, the remaining 18 participants in the same dose group proceeded and sentinels in block 2 were given their first administration on a two-dose schedule, 28 days apart. All participants, investigators, and staff doing laboratory analyses were masked to treatment allocation. Humoral responses were assessed by measuring anti-SARS-CoV-2 RBD IgG using a standardised ELISA and neutralising antibodies using pseudovirus-based and live SARS-CoV-2 neutralisation assays. SARS-CoV-2 RBD-specific T-cell responses, including IFN-γ and IL-2 production, were assessed using an enzyme-linked immunospot (ELISpot) assay. The primary outcome for safety was incidence of adverse events or adverse reactions within 60 min, and at days 7, 14, and 28 after each vaccine dose. The secondary safety outcome was abnormal changes detected by laboratory tests at days 1, 4, 7, and 28 after each vaccine dose. For immunogenicity, the secondary outcome was humoral immune responses: titres of neutralising antibodies to live SARS-CoV-2, neutralising antibodies to pseudovirus, and RBD-specific IgG at baseline and 28 days after first vaccination and at days 7, 15, and 28 after second vaccination. The exploratory outcome was SARS-CoV-2-specific T-cell responses at 7 days after the first vaccination and at days 7 and 15 after the second vaccination. This trial is registered with www.chictr.org.cn (ChiCTR2000039212). FINDINGS Between Oct 30 and Dec 2, 2020, 230 individuals were screened and 120 eligible participants were randomly assigned to receive five-dose levels of ARCoV or a placebo (20 per group). All participants received the first vaccination and 118 received the second dose. No serious adverse events were reported within 56 days after vaccination and the majority of adverse events were mild or moderate. Fever was the most common systemic adverse reaction (one [5%] of 20 in the 5 μg group, 13 [65%] of 20 in the 10 μg group, 17 [85%] of 20 in the 15 μg group, 19 [95%] of 20 in the 20 μg group, 16 [100%] of 16 in the 25 μg group; p<0·0001). The incidence of grade 3 systemic adverse events were none (0%) of 20 in the 5 μg group, three (15%) of 20 in the 10 μg group, six (30%) of 20 in the 15 μg group, seven (35%) of 20 in the 20 μg group, five (31%) of 16 in the 25 μg group, and none (0%) of 20 in the placebo group (p=0·0013). As expected, the majority of fever resolved in the first 2 days after vaccination for all groups. The incidence of solicited systemic adverse events was similar after administration of ARCoV as a first or second vaccination. Humoral immune responses including anti-RBD IgG and neutralising antibodies increased significantly 7 days after the second dose and peaked between 14 and 28 days thereafter. Specific T-cell response peaked between 7 and 14 days after full vaccination. 15 μg induced the highest titre of neutralising antibodies, which was about twofold more than the antibody titre of convalescent patients with COVID-19. INTERPRETATION ARCoV was safe and well tolerated at all five doses. The acceptable safety profile, together with the induction of strong humoral and cellular immune responses, support further clinical testing of ARCoV at a large scale.

Abstract
This study reviewed the clinical data of patients who were hospitalized in the Department of Neurology of Henan Provincial People's Hospital from January 2017 to October 2020. A total of 46 patients with positive serum anti-CV2 antibody were included. The average age of the patients was (54±15) years old, with a male to female ratio of 1.88∶1. Twenty-six patients were diagnosed with paraneoplastic neurological syndrome (PNS). The most malignant tumors were thymoma, small cell lung cancer, and prostate cancer. The most common PNS included myasthenia gravis, subacute cerebellar degeneration, and subacute/chronic sensorimotor neuropathies. Twenty non-PNS patients exhibited subacute/old cerebral infarction, Parkinson's disease, Alzheimer's disease, and so on. Among them, brain magnetic resonance imaging (MRI) of 10 cases showed different degrees of white matter demyelination, some of which were accompanied by brain atrophy. The current study found that the positive predictive value of anti-CV2 antibody for the diagnosis of PNS was 56.5%, which was relatively weak. As an accompanying antibody, it may be a coincidence, and it may also be related to the involvement of family members in the pathological process of the diseases.

Abstract
The non-alcoholic fatty liver disease (NAFLD) fibrosis score (NFS) has emerged as a useful predictor of long-term outcome in NAFLD patients. We evaluated the predictive performance of the NFS for overall mortality in a Chinese population with NAFLD. All NAFLD patients diagnosed ultrasonographically at Xixi Hospital of Hangzhou between 1996 and 2011 were retrospectively recruited to the study. Outcome was determined by interview and causes of death were confirmed by medical records. The area under the receiver operating characteristic curve (AUCROC ) was used to determine the predictive accuracy of the NFS, BARD (body mass index, aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio, diabetes) score, FIB-4 index and the AST/platelet ratio index (APRI) for mortality. Data from a total of 180 eligible patients (median age 39 years; 96 men) were analysed, with 12 deaths over a median follow-up period of 6.6 years (range 0.5-14.8 years). Using Cox model analysis, the NFS as a continuous variable was identified as the only predictor for all-cause mortality (hazard ratio 2.743, 95% confidence interval (CI) 1.670-4.504). The NFS yielded the highest AUCROC of 0.828 (95% CI 0.728-0.928, P < 0.05), followed by the FIB-4 index, APRI and BARD score (AUCROC 0.806 (P < 0.05), 0.732 (P < 0.05) and 0.632, respectively). The data indicated that the NFS is a useful predictor of 6.6-year all-cause mortality for Chinese patients with NAFLD.

Abstract
Raman spectroscopy has been shown to have the potential for revealing oxygenated and spin ability of hemoglobin. In this study, confocal micro-Raman spectroscopy is developed to monitor the effect of sodium nitrite on oxyhemoglobin (HbO2 ) in whole blood. We observe that the band at 1,638 cm(-1) which is sensitive to the oxidation state decreases dramatically, while the 1,586 cm(-1) (low-spin state band) reduces both in methemoglobin (MetHb) and poisoning blood. Our results show that adding in sodium nitrite lead to the transition from HbO2 (Fe(2+) ) to MetHb (Fe(3+) ) in whole blood, and the iron atom converts from the low spin state to the high spin state with a delocalization from porphyrin plane. Moreover, multivariate statistical techniques, including principal components analysis (PCA) and linear discriminant analysis (LDA) are employed to develop effective diagnostic algorithms for classification of spectra between pure blood and poisoning blood. The diagnostic algorithms based on PCA-LDA yield a diagnostic sensitivity of 100% and specificity of 100% for separating poisoning blood from normal blood. Receiver operating characteristic (ROC) curve further confirms the effectiveness of the diagnostic algorithm based on PCA-LDA technique. The results from this study demonstrate that Raman spectroscopy combined with PCA-LDA algorithms has tremendous potential for the non-invasive detection of nitrite poisoning blood.

Abstract
AIM: To evaluate the predictive effect of baseline hepatitis B surface antigen (HBsAg) on response to pegylated interferon (PEG-IFN)-α2b in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients.
METHODS: This retrospective analysis compared the treatment efficacy of PEG-IFN-α2b alone in 55 HBeAg-positive CHB patients with different baseline HBsAg levels. Serum HBV DNA load was measured at baseline, and at 12, 24 and 48 wk of therapy. Virological response was defined as HBV DNA < 1000 IU/mL. Serum HBsAg titers were quantitatively assayed at baseline, and at 12 and 24 wk.
RESULTS: Eighteen patients had baseline HBsAg > 20 000 IU/mL, 26 patients had 1500-20000 IU/mL, and 11 patients had < 1500 IU/mL. Three (16.7%), 11 (42.3%) and seven (63.6%) patients in each group achieved a virological response at week 48, with a significant difference between groups with baseline HBsAg levels > 20000 or < 20000 IU/mL (P = 0.02). Thirteen patients had an HBsAg decline > 0.5 log10 and 30 patients < 0.5 log10 at week 12; and 6 (46.2%) and 10 (33.3%) in each group achieved virological response at week 48, with no significant difference between the two groups (P = 0.502). Eighteen patients had an HBsAg decline > 1.0 log10 and 30 patients < 1.0 log10 at week 24, and 8 (44.4%) and 11 (36.7%) achieved a virological response at week 48, with no significant difference between the two groups (P = 0.762). None of the 16 patients with HBsAg > 20000 IU/mL at week 24 achieved a virological response at week 48.
CONCLUSION: Baseline HBsAg level in combination with HBV DNA may become an effective predictor for guiding optimal therapy with PEG-IFN-α2b against HBeAg-positive CHB.

Abstract
OBJECTIVE To investigate the relation of hepatitis B surface antigen (HBsAg) level with chronic hepatitis B (CHB) and liver inflammation and fibrosis. METHODS A total of 301 patients who diagnosed CHB and underwent liver biopsy were enrolled into the study. Meantimes, the biochemical markers, ferritin (FERR), serum HBsAg and HBV DNA quantitation were detected. The relation between HBsAg level and liver pathology were determined by spearman rank correlation analysis. The receiver operating characteristic curve was used to evaluate the accuracy of HBsAg level for liver inflammation and fibrosis. RESULTS The body mass index (BMI), age, gender, genotype and family history had no effective on liver inflammation and fibrosis (P < 0.05). With the progressing of inflammation and fibrosis, the serum AST and ALT raise obviously (chi2 = 71.193, 96.344, 47.847, 63.981; P = 0.000, 0.000, 0.000, 0.000). When fibrosis reached to S4, the level of HBV DNA decreased obviously (chi2 = 33. 322; P = 0.000). With the aggravation of inflammation and fibrosis, the serum HBsAg gradually descended (chi2 = 68.173,15.719; P = 0.000, 0.000). The areas under operating characteristics curves of HBsAg predicted < or = G3 and < or = S3 were 0.732 and 0.793, and the specificity were 0.778, 0.891, and sensitivity were 0.685, and 0.633, respectively. CONCLUSION The level of HBsAg of Chinese CHB patients descended gradually with the aggravation of liver inflammation and fibrosis. The serum HBsAg had a higher specificity to predict < or = G3 and < or = S3 of CHB patients. But there had superiority of predicting fibrosis than inflammation.

Abstract
Second harmonic microscopic imaging and spectroscopy technology has become a powerful tool for biomedical studies, especially in fibrosis-related diseases research. And type I collagen is the major risk factors for fibrotic diseases. In this study, model for three-dimensional (3-D) uniform arrangement type I collagen is set up for researching the second harmonic generation (SHG) on nonlinear optics microscopy. Based on this model, we discuss the influence of different length and size collagen in 3-D arrangement type I collagen. Results can guide us to neatly judge the size, length, and molecules density effect on SHG. For practical application, this theoretical approach can lead us to analyze different severity of collagen diseases.

Abstract
OBJECTIVE To understand the genotype characteristics and its evolution of patients with poor response to initial combined treatment of Lamivudine and Adefovir dipivoxil for chronic hepatitis B. METHODS We detected the HBV genotypes of three patients-S1, S2, S3, who with poor response to initial treatment of Lamivudine and Adefovir dipivoxil for chronic hepatitis B over 12 months by the application of cloning and sequencing method at the time point of baseline,4 weeks after treatment, 12 weeks, 24 weeks, 48 weeks, 60 weeks. 25 clones were randomly selected to identify and sequence at each time point. RESULTS The total number of clones from 3 patients with poor response to initial combined treatment of Lamivudine and Adefovir dipivoxil for chronic hepatitis B at each time point was 398. About patient S1 at baseline, genotype C accounting for 8.3%, genotype B, for 91.7%, so genotype B was in dominant (22/24). But genotype C has gradually developed to 100% after treatment for 60 weeks. About patient S2 and S3, genotype B was the only type at baseline. However type B has gradually "drift" to type C during treatment. When treatment for 60 weeks, type C has taken the absolute advantage 75% for S2, and 100% for S3. CONCLUSIONS The cloning and sequencing can represent the overall genotype level better. HBV genotype has performed the evolution trend that genotype has drifted from B to C during long-term drug pressure, which is the main reason for poor response to initial combined treatment of Lamivudine and Adefovir dipivoxil for chronic hepatitis B.

Abstract
OBJECTIVE To investigate 3-year antiviral efficacy and side effect of adefovir dipivoxil (ADV) on the old patients with hepatitis B chronic infection. METHODS 31 HBeAg-negative chronic hepatitis B virus infected old patients (include 8 patients with chronic hepatitis B and 23 patients with liver cirrhosis) with serum HBV DNA levels > 1000 copies/ml, and ALT > 2 times the upper limit of normal, without company with other liver diseases, cancer, renal dysfunction, and autoimmune disease. All the patients were treated with ADV orally (10 mg once daily) for 36 months. HBV DNA and biochemical and blood routine indexes were checked after treated. RESULT Serum total bilirubin, direct bilirubin, alamine aminotransferase, aspartate aminotransferase and load of HBV DNA decrease significantly after therapy (P < 0. 001). Other biochemical indexs and blood routine are no significant changes (P > 0.05). CONCLUSION The way to treat with ADV is safe and effective for old patients with chronic hepatitis B virus infection.

Abstract
A simple method for preparing solvent-resistant nanofibers with a thermal-sensitive surface has been developed by the combined technology of reversible addition-fragmentation chain-transfer (RAFT) polymerization, atom transfer radical polymerization (ATRP), electrospinning, and "click chemistry". Initially, well-defined block copolymers of 4-vinylbenzyl chloride (VBC) and glycidyl methacrylate (GMA) (PVBC-b-PGMA) were prepared via RAFT polymerization. Electrospinning of PVBC-b-PGMA from a solution in tetrahydrofuran gave rise to fibers with diameters in the range of 0.4-1.5 microm. Exposure to a solution of sodium azide (NaN(3)) not only affords nanofibers with azido groups on the surface but also leads to a cross-linking structure in the nanofibers. One more step of "click chemistry" between the PVBC-b-PGMA nanofibers with azido groups on the surface (PVBC-b-PGMA(-N3)) and alkyne-terminated polymers of N-isopropylacrylamide (NIPAM) (PNIPAM(AT)), which were prepared by ATRP, allows the preparation of a PVBC-b-PGMA nanofiber with thermal-sensitive PNIPAM brushes on the surface (PVBC-b-PGMA-g-PNIPAM). PVBC-b-PGMA-g-PNIPAM nanofibers exhibit a good resistance to solvents and thermal-responsive character to the environment, having a hydrophobic surface at 45 degrees C (water contact angle approximately 140 degrees) and having a hydrophilic surface at 20 degrees C (water contact angle approximately 30 degrees).

Abstract
A modified cellular automaton (MCA) coupled with a momentum and species transport model has been developed in order to predict the evolution of dendritic morphology during solidification of alloys in the presence of melt convection. In the present model, the cellular automaton algorithm for dendritic growth is incorporated with the transport model, for calculating fluid flow and mass transfer by both convention and diffusion. The MCA model takes into account the effects of the constitutional undercooling and the curvature undercooling on the equilibrium interface temperature. It also considers the preferred growth orientation of crystals and solute redistribution during solidification. In the transport model, which is coupled with cellular automaton approach, the SIMPLE scheme is employed to solve the governing equations of momentum and species transfers. The present model was applied to model solutal dendritic growth of an Al-3mass%Cu alloy in a forced flow. The simulations reproduced the typical asymmetric growth features of convective dendrites with various preferred orientations. The effects of inlet flow velocity on the solute redistribution and the growth velocity of a dendritic tip were quantitatively investigated.

Abstract
The function of ANP in the cardiovascular regulation is very similar with the TCM theory of "the Heart governs blood circulation". Using the method of cardiac impedance to check cardiac output and the method of radioimmunoassay (RIA) to check plasma ANP, the result showed that in the status of Blood Deficiency Syndrome, cardiac function was impaired, there were reduced kinemia and stroke volume, as well as markedly raised plasma ANP and peripheral resistance. The above-mentioned indexes were significantly different from those of normal group (P < 0.01). Using multivariate regression analysis, cardiac output was negatively correlated with the plasma ANP (P < 0.05). 23 cases with Blood Deficiency Syndrome showed normal hemoglobin, but an evidently changed cardiac output and plasma ANP were closely related with the level of the Blood Deficiency. Both parameters might serve as the objective basis to reflect the level of Blood Deficiency to facilitate the clinical diagnosis of the patient.
