Abstract
Objective: To explore the clinical changes in levels of the new clinical marker serum hepatitis B virus (HBV) pregenomic RNA (pgRNA) in patients with chronic hepatitis B (CHB) with long-term antiviral therapy. Methods: 100 CHB cases who were initially treated with nucleos(t)ide analogues (NAs) at Peking University First Hospital were included. The levels of alanine aminotransferase (ALT), HBV DNA, hepatitis B e-antigen (HBeAg), and hepatitis B surface antigen (HBsAg) during the follow-up period were measured. The TaqMan-based real-time quantitative PCR method was used to detect serum HBV pgRNA levels. The independent sample t-test and Mann-Whitney U test were used to compare continuous variables between groups, while Pearson's χ (2) test and Fisher's exact test were used to compare categorical variables. Results: HBV pgRNA levels decreased significantly in patients who developed virological responses at 48 weeks (n = 54) during subsequent treatment compared to those who did not (n = 46). The HBV pgRNA level was lower in HBeAg-positive patients than in HBeAg-negative patients (P < 0.05 or P < 0.01). Patients with higher HBV DNA and HBeAg-positivity levels at baseline had a higher HBV pgRNA level following antiviral therapy. There was no statistically significant difference in HBV pgRNA levels in patients with different HBV pgRNA levels at baseline after antiviral therapy. There was no correlation between serum HBV pgRNA and HBsAg at baseline, but there was a correlation after long-term antiviral therapy, while there was a weak correlation between HBV pgRNA and HBsAg at the fifth and ninth years of antiviral therapy (r = 0.262, P = 0.031; r = 0.288, P = 0.008). Conclusion: HBV pgRNA levels were higher with higher HBV activity in CHB patients with long-term antiviral therapy.

Abstract
Objective: To explore the effects of resistance training with elastic band at home on muscle function and walking ability of severely burned children. Methods: A prospective non-randomized controlled study was conducted. From January 2022 to April 2023, 40 children with severe burns who met the inclusion criteria were admitted to Tongren Hospital of Wuhan University & Wuhan Third Hospital. According to the willingness of the children or their families, the children were assigned to conventional rehabilitation group and combined rehabilitation group. During the study, 8 children dropped out of the study, 17 children were finally included in the conventional rehabilitation group with 6 males and 11 females, aged (8.5±2.4) years, and 15 children were included in the combined rehabilitation group with 5 males and 10 females, aged (9.6±2.5) years. The children in the 2 groups received conventional burn rehabilitation treatment in the hospital, including active and passive activity training, scar massage, and pressure therapy. The children in combined rehabilitation group received resistance training with elastic band of 3 to 5 times per week after discharge, and the children in conventional rehabilitation group received daily activity ability training after discharge. Before home rehabilitation training (1 week before discharge) and 12 weeks after home rehabilitation training, the grip strength was measured using a handheld grip dynamometer, the muscle strengths of the upper and lower limbs were measured using a portable dynamometer for muscle strength, lean body mass was measured by bioelectrical impedance measuring instrument, and the 6-min walking distance was measured. Data were statistically analyzed with independent sample t test, paired sample t test, Mann-Whitney U test, or Fisher's exact probability test. Results: After 12 weeks of home rehabilitation training, the grip strengths of children in combined rehabilitation group and conventional rehabilitation group were (15±4) and (11±4) kg, respectively, which were significantly higher than (10±4) and (9±4) kg before home rehabilitation training (with t values of -9.99 and -11.89, respectively, P values all <0.05); the grip strength of children in combined rehabilitation group was significantly higher than that in conventional rehabilitation group (t=3.24, P<0.05). After 12 weeks of home rehabilitation training, the muscle strengths of upper and lower limbs of children in combined rehabilitation group (with t values of -11.39 and -3.40, respectively, P<0.05) and the muscle strengths of upper and lower limbs of children in conventional rehabilitation group (with t values of -7.59 and -6.69, respectively, P<0.05) were significantly higher than those before home rehabilitation training, and the muscle strengths of upper and lower limbs of children in combined rehabilitation group were significantly higher than those in conventional rehabilitation group (with t values of 3.80 and 7.87, respectively, P<0.05). After 12 weeks of home rehabilitation training, the lean body mass of children in combined rehabilitation group was significantly higher than that before home rehabilitation training (t=0.21, P<0.05). After 12 weeks of home rehabilitation training, the 6-min walking distances of children in conventional rehabilitation group and combined rehabilitation group were significantly longer than those before home rehabilitation training (with t values of -5.33 and -3.40, respectively, P<0.05), and the 6-min walking distance of children in combined rehabilitation group was significantly longer than that in conventional rehabilitation group (t=3.81, P<0.05). Conclusions: Conventional burn rehabilitation treatment in hospital and home resistance training with elastic band for 12 weeks after discharge can significantly improve the muscle function and walking ability of severely burned children.

Abstract
Previously, liver lesions in cirrhosis were considered irreversible, especially because the condition aggravated gradually after entering the decompensated phase, thus making it difficult to return to the compensated phase. At present, more and more evidence shows that some patients with decompensated liver cirrhosis can be recompensated after the cause is controlled and complications are managed. This article explores the research progress related to LC reversal and recompensation from three aspects: liver histopathology, liver function, and clinical complications.

Abstract
Objective: To analyze the occurrence of recompensation conditions in patients with chronic hepatitis B virus-related decompensated cirrhosis after entecavir antiviral therapy. Methods: Patients with hepatitis B virus-related decompensated cirrhosis with ascites as the initial manifestation were prospectively enrolled. Patients who received entecavir treatment for 120 weeks and were followed up every 24 weeks (including clinical endpoint events, hematological and imaging indicators, and others) were calculated for recompensation rates according to the Baveno VII criteria. Measurement data were compared using the Student t-test or Mann-Whitney U test between groups. Categorical data were compared by the χ (2) test or Fisher's exact probability method between groups. Results: 283 of the 320 enrolled cases completed the 120-week follow-up, and 92.2% (261/283) achieved a virological response (HBV DNA 20 IU/ml). Child-Pugh and MELD scores were significantly improved after treatment (8.33 ± 1.90 vs. 5.77 ± 1.37, t = 12.70, P < 0.001; 13.37 ± 4.44 vs. 10.45 ± 4.58, t = 5.963, P < 0.001). During the 120-week follow-up period, 14 cases died, two received liver transplants, 19 developed hepatocellular cancer, 11 developed gastroesophageal variceal bleeding, and four developed hepatic encephalopathy. 60.4% (171/283) (no decompensation events occurred for 12 months) and 56.2% (159/283) (no decompensation events occurred for 12 months and improved liver function) of the patients had achieved clinical recompensation within 120 weeks. Patients with baseline MELD scores > 15 after active antiviral therapy achieved higher recompensation than patients with baseline MELD scores ≤15 [50/74 (67.6%) vs. 109/209 (52.2%), χ (2) = 5.275, P = 0.029]. Conclusion: Antiviral therapy can significantly improve the prognosis of patients with hepatitis B virus-related decompensated cirrhosis. The majority of patients (56.2%) had achieved recompensation. Patients with severe disease did not have a lower probability of recompensation at baseline than other patients.

Abstract
Objective: To understand ten-year changes in clinical characteristics and antiviral treatment patterns of chronic hepatitis B in China. Methods: Patients with chronic HBV infection:demographic, virologic, hematologic, blood biochemistry, and antiviral treatment data were extracted from the China Registry of Hepatitis B (CR-HepB) database between 2012 and 2022 for descriptive statistics and change trend analysis. Multiple group comparisons were conducted using the Kruskal Wallis H test, while counting data was compared between groups using χ (2) test. Results: A total of 180 012 patients with chronic HBV infection were included, with a median age of 40 years old, and a male proportion accounting for 60.2%. The HBeAg positive rate was 43.3%. Over time, the median age of new patients each year increased from 39 to 47 years, while the HBeAg positive rate decreased from 51.3% to 32.8%. The initial diagnosis of patients was mainly CHB (71.4%), followed by hepatitis B cirrhosis (11.8%), inactive HBsAg carrier status (10.6%), and chronic HBV carrier status (6.2%). Among the newly registered patients every year from 2012 to 2022, the proportion of hepatitis B cirrhosis remained stable, but after 2019, the proportion of CHB increased and the proportion of other diagnoses decreased. The proportion of patients with cirrhosis increased with age in different age groups, with 3.5%, 19.3%, and 30.4% in the < 40, 40-69, and≥70 age groups, respectively. The proportion of women in patients with cirrhosis also increased with age, from 16.1% in those < 30 years old to 44.3% in those≥80 years old. From 2012 to 2022, the proportion of patients receiving first-line nucleos(t)ide analog antiviral treatment increased year by year, from 51.0% in 2012-2013 to 99.8% in 2022. Conclusion: The CR-HepB registration data reflect the changes in clinical characteristics and antiviral treatment patterns in patients with chronic HBV infection in China over the past ten years and can thus provide a reference to promote hepatitis B diagnosis and treatment practice, as well as scientific research.

Abstract
Objective: To assess the safety and efficacy of transcatheter fenestration closure following Fontan procedure with an atrial septal occluder. Methods: This is a retrospective study. The study sample consists of all consecutive patients who underwent closure of a fenestrated Fontan baffle at Shanghai Children's Medical Center Affiliated to Shanghai Jiaotong University School of Medicine between June 2002 and December 2019. The indications of Fontan fenestration closure included that normal ventricular function, targeted drugs for pulmonary hypertension and positive inotropic drugs were not required prior the procedure; and the Fontan circuit pressure was less than 16 mmHg (1 mmHg=0.133 kPa) and no more than a 2 mmHg increase during test occlusion of the fenestration. Electrocardiogram and echocardiography were reviewed at 24 hours, 1, 3, 6 months and annually thereafter post procedure. Follow-up information including clinical events and complications related to Fontan procedure was recorded. Results: A total of 11 patients, including 6 males and 5 females, aged (8.9±3.7) years old were included. The types of Fontan were extracardiac conduits (7 cases) and intra-atrial duct (4 cases). The interval between percutaneous fenestration closure and the Fontan procedure was (5.1±2.9) years. One patient reported recurrent headache after Fontan procedure. Successful fenestration occlusion with atrial septal occluder was achieved in all patients. Compared with prior closure, Fontan circuit pressure ((12.72±1.90) mmHg vs. (12.36±1.63) mmHg, P<0.05), and aortic oxygen saturation ((95.11±3.11)% vs. (86.35±7.26)%, P<0.01) were increased. There were no procedural complications. At a median follow-up of (3.8±1.2) years, there was no residual leak and evidence of stenosis within the Fontan circuit in all patient. No complication was observed during follow-up. One patient with preoperative headache did not have recurrent headache after closure. Conclusions: If the Fontan pressure is acceptable by test occlusion during the catheterization procedure, Fontan fenestration could be occluded with the atrial septum defect device. It is a safe and effective procedure, and could be used for occlusion of Fontan fenestration with varying sizes and morphologies.

Abstract
Multipartite entanglements are essential resources for proceeding tasks in quantum information science and technology. However, generating and verifying them present significant challenges, such as the stringent requirements for manipulations and the need for a huge number of building-blocks as the systems scale up. Here, we propose and experimentally demonstrate the heralded multipartite entanglements on a three-dimensional photonic chip. Integrated photonics provide a physically scalable way to achieve an extensive and adjustable architecture. Through sophisticated Hamiltonian engineering, we are able to control the coherent evolution of shared single photon in the multiple spatial modes, dynamically tuning the induced high-order W-states of different orders in a single photonic chip. Using an effective witness, we successfully observe and verify 61-partite quantum entanglements in a 121-site photonic lattice. Our results, together with the single-site-addressable platform, offer new insights into the accessible size of quantum entanglements and may facilitate the developments of large-scale quantum information processing applications.

Abstract
The spatial distribution and abundance of suspected microplastics (SMPs) in the surface water of a metropolitan city, as represented by four Hong Kong rivers, was studied during the dry season. Shing Mun River (SM), Lam Tsuen River (LT), and Tuen Mun River (TM) are located in urbanized areas, and SM and TM are tidal rivers. The fourth river, Silver River (SR) is situated in a rural area. TM had a significantly higher SMP abundance (53.80 ± 20.67 n/L) than the other rivers. The SMP abundance increased from upstream to downstream in non-tidal rivers (LT and SR), but not in tidal rivers (TM and SM), probably due to the tidal influence and a more homogeneous urban development along the tidal rivers. Inter-site differences in the SMP abundance were strongly correlated with the built area ratio (defined as the percentage of surrounding developed land area), human activities, and the nature of the river. About half (48.72 %) of the SMPs were <250 μm. Fibers and fragments were most abundant (>98 %), with most of them being transparent (58.54 %), black (14.68 %), or blue (12.12 %). Polyethylene terephthalate (26.96 %) and polyethylene (20.70 %) were the most common polymers. However, the MP abundance could be overestimated due to the presence of natural fibers. By contrast, an underestimation of the MP abundance could result from a smaller volume of water samples collected, due to a low filtration efficiency caused by high organic content and particle concentrations in the water. A more effective solid waste management strategy and upgrading of the sewage treatment facilities for removing microplastics are recommended to ameliorate the microplastic pollution in local rivers.

Abstract
Patients with either a repaired or medically managed aortic dissection have varying degrees of risk of developing late complications. High-risk patients would benefit from earlier intervention to improve their long-term survival. Currently serial imaging is used for risk stratification, which is not always reliable. On the other hand, understanding aortic haemodynamics within a dissection is essential to fully evaluate the disease and predict how it may progress. In recent decades, computational fluid dynamics (CFD) has been extensively applied to simulate complex haemodynamics within aortic diseases, and more recently, four-dimensional (4D)-flow magnetic resonance imaging (MRI) techniques have been developed for in vivo haemodynamic measurement. This paper presents a comprehensive review on the application of image-based CFD simulations and 4D-flow MRI analysis for risk prediction in aortic dissection. The key steps involved in patient-specific CFD analyses are demonstrated. Finally, we propose a workflow incorporating computational modelling for personalised assessment to aid in risk stratification and treatment decision-making.

Abstract
Objective: To investigate the efficacy of chitinase-3-like protein 1 (CHI3L1) and Golgi protein 73 (GP73) in the diagnosis of cirrhosis and the dynamic changes of CHI3L1 and GP73 after HCV clearance in patients with chronic hepatitis C (CHC) treated with direct-acting antiviral drugs (DAAs). The comparison of continuous variables of normal distribution were statistically analyzed by ANOVA and t-test. The comparison of continuous variables of non-normal distribution were statistically analyzed by rank sum test. The categorical variables were statistically analyzed by Fisher's exact test and χ(2) test. Correlation analysis was performed using Spearman correlation analysis. Methods: Data of 105 patients with CHC diagnosed from January 2017 to December 2019 were collected. The receiver operating characteristic curve (ROC curve) was plotted to study the efficacy of serum CHI3L1 and GP73 for the diagnosis of cirrhosis. Friedman test was used to compare CHI3L1 and GP73 change characteristics. Results: The areas under the ROC curve for CHI3L1 and GP73 in the diagnosis of cirrhosis at baseline were 0.939 and 0.839, respectively. Serum levels of CHI3L1 and GP73 in the DAAs group decreased significantly at the end of treatment compared with baseline [123.79 (60.25, 178.80) ng/ml vs. 118.20 (47.68, 151.36) ng/ml, P = 0.001; 105.73 (85.05, 130.69) ng/ml vs. 95.52 (69.52, 118.97) ng/ml, P = 0.001]. Serum CHI3L1 and GP73 in the pegylated interferon combined with ribavirin (PR) group were significantly lower at the end of 24 weeks of treatment than the baseline [89.15 (39.15, 149.74) ng/ml vs. 69.98 (20.52, 71.96) ng/ml, P < 0.05; 85.07 (60.07, 121) ng/ml vs. 54.17 (29.17, 78.65) ng/ml, P < 0.05]. Conclusion: CHI3L1 and GP73 are sensitive serological markers that can be used to monitor the fibrosis prognosis in CHC patients during treatment and after obtaining a sustained virological response. Serum CHI3L1 and GP73 levels in the DAAs group decreased earlier than those in the PR group, and the serum CHI3L1 levels in the untreated group increased compared with the baseline at about two years of follow-up.

Abstract
Objective: To establish and validate a nomogram model for predicting the risk of microvascular invasion(MVI) in hepatocellular carcinoma. Methods: The clinical data of 210 patients with hepatocellular carcinoma who underwent hepatectomy at Department of Hepatobiliary and Pancreatic Surgery,the Affiliated Hospital of Qingdao University from January 2013 to October 2021 were retrospectively analyzed. There were 169 males and 41 females, aged(M(IQR)) 57(12)years(range:30 to 80 years). The patients were divided into model group(the first 170 cases) and validation group(the last 40 cases) according to visit time. Based on the clinical data of the model group,rank-sum test and multivariate Logistic regression analysis were used to screen out the independent related factors of MVI. R software was used to establish a nomogram model to predict the preoperative MVI risk of hepatocellular carcinoma,and the validation group data were used for external validation. Results: Based on the modeling group data,the receiver operating characteristic curve was used to determine that cut-off value of DeRitis ratio,γ-glutamyltransferase(GGT) concentration,the inverse number of activated peripheral blood T cell ratio (-aPBTLR) and the maximum tumor diameter for predicting MVI, which was 0.95((area under curve, AUC)=0.634, 95%CI: 0.549 to 0.719), 38.2 U/L(AUC=0.604, 95%CI: 0.518 to 0.689),-6.05%(AUC=0.660, 95%CI: 0.578 to 0.742),4 cm(AUC=0.618, 95%CI: 0.533 to 0.703), respectively. Univariate and multivariate Logistic regression analysis showed that DeRitis≥0.95,GGT concentration ≥38.2 U/L,-aPBTLR>-6.05% and the maximum tumor diameter ≥4 cm were independent related factors for MVI in hepatocellular carcinoma patients(all P<0.05). The nomogram prediction model based on the above four factors established by R software has good prediction efficiency. The C-index was 0.758 and 0.751 in the model group and the validation group,respectively. Decision curve analysis and clinical impact curve showed that the nomogram model had good clinical benefits. Conclusions: DeRitis ratio,serum GGT concentration,-aPBTLR and the maximum tumor diameter are valuable factors for preoperative prediction of hepatocellular carcinoma with MVI. A relatively reliable nomogram prediction model could be established on them.

Abstract
Natural snowflakes exhibit remarkable diversity with a fascinating sixfold symmetry and fractal structure. Efforts to discover the snow crystal growth pattern and mechanism behind it have been made in the past 50 years. Among those, cellular automata (CA) have made certain progress. To investigate the influence of latent heat release in snow crystal growth and have a deeper understanding of crystal growth characteristics, an improved CA model combined with vapor diffusion and heat diffusion is proposed to investigate the snowflake growth process in a two-dimensional and nonisothermal field in this paper. Simulation results show that obtained snow crystal growth behavior is consistent with previous experimental observations and satisfies the crystal growth dynamic theory. Latent heat release impacts the small structure of snow crystals, and it could have a more significant influence on snowflake morphology when vapor diffusion is slow and heat diffusion is dominating.

Abstract
Objective: To investigate the clinical symptoms and cone-beam CT (CBCT) imaging characteristics of temporomandibular joint osteoarthritis (TMJOA) with chewing side preference (CSP). Methods: One hundred patients with TMJOA diagnosed in the Department of Stomatology, General Hospital of the Chinese PLA from January 2018 to December 2020 were enrolled, including 32 males and 68 females, with an median age of 27.5 years (16-71 years). According to the habit of CSP, 100 cases were divided into 71 cases of TMJOA with CSP group and 29 cases of TMJOA without CSP group. The clinical symptoms were observed, including pain, TMJ sounds, limited mouth opening as well as the radiograph imaging changes of condylar bone. When analyzing the radiograph imaging changes of condylar, the cases with bilateral TMJ symptoms were excluded and the remaining cases were divided into symptomatic sides and asymptomatic sides with CSP or without CSP according to the symptoms of the chief complaint. SPSS 25.0 was used to analyze the statistical data. Age data did not conform to normal distribution so that median and quartile spacing were used for description, and Mann-Whitney U test was used for nonparametric test. Qualitative data such as gender, clinical symptoms and condylar lesion types were described by composition ratio and Chi-Square test was performed. Results: There was no statistical significance in age and gender of TMJOA patients in the group with or without CSP (P>0.05). There incidence of pain in CSP group [83.1% (59/71)] was margina uy higher than that in non-CSP group but without statistical difference[65.5% (19/29)] (χ²=3.71, P=0.054). There was also no significant difference in TMJ sounds and limitation of mandibular movement between the two groups(χ²=0.11, P=0.742; χ²=0.48, P=0.489). Among all of joints, the most common types of TMJOA were articular flattening and shortening and erosion. CBCT showed that erosion [65.0% (130/200)], flattening and shortening [73.0% (146/200)], subcortical sclerosis [42.0% (84/200)], osteophyte [30.5% (61/200)] and subcortical cystic [15.5% (31/200)]. According to the different groups of chief complaint sides, intra-group comparisons show that the proportion of erosion in symptomatic sides of CSP group [80.0% (40/50)] was significantly higher than that in asymptomatic sides of CSP group [50.0% (25/50)] (χ²=9.89, P=0.002). Inter-group comparisons show that the proportion of condyle flattening and shortening in symptomatic sides of CSP group [84.0% (42/50)] was significantly higher than that in bilateral joint of non-CSP group (8/15) (χ²=8.81, P=0.032). There was no significant difference in the proportion of subcortical sclerosis, osteophyte and subcortical cystic between the group with or without CSP (P>0.05). Conclusions: TMJOA patients with CSP may be more prone to clinical symptoms of pain and CBCT imaging changes of condyle erosion as well as flattening and shortening. CSP may be a promoting factor for the development of TMJOA.

Abstract
Objective: To investigate the effects of high-flow nasal oxygen (HFNO) combined with early extubation on the incidence of respiratory adverse events (RAE) during emergence from general anesthesia in children undergoing adenoid-tonsillectomy. Methods: From December 2021 to January 2022, 40 pediatric patients [21 males, 19 females, with a median age of 4 (4, 5) years] undergoing tonsillectomy and/or adenoidectomy in Eye & ENT Hospital of Fudan University were randomly divided into two groups: HFNO-assisted early extubation group (Group H, n=20) and conventional extubation group (Group C, n=20) by using a random number table. After entering the post-anesthesia care unit (PACU), the patients in group H received humidified and heated oxygen (flow rate: 25 L/min) through a nasal cannula until their consciousness regained. After patient's spontaneous breathing resumed for 10 min, the oral endotracheal tube was removed. Patients in group C did not receive HFNO. The oral endotracheal tube was removed after the patient's spontaneous breathing resumed for at least 10 min with signs of tube intolerance, or 20 min without signs of tube intolerance. During the PACU stay, the incidence of RAE, the incidence of cough, the application rate of intensive care strategy, the time to extubation, the duration of PACU stay, and vital signs at spontaneous breathing resuming and extubation in each group were recorded. Results: In Group H, the total incidence of RAE [30% (6/20) vs 65% (13/20), P=0.027], the incidence of cough [10% (2/10) vs 45% (9/20), P=0.031] and the application rate of intensive care strategy [20% (4/20) vs 55% (11/20), P=0.048] during PACU stay was significantly lower, compared with those of Group C. Likewise, the time to extubation was significantly shorter [(33.4±4.5) min vs (42.7±5.3) min, P<0.001]. However, there was no statistically significant difference in the duration of PACU stay, the vital signs at the time of spontaneous breathing resuming and extubation between the two groups (P>0.05), except that the end-tidal carbon dioxide partial pressure (PETCO2) at the time of extubation in group H was significantly higher than group C [(52.9±9.4) mmHg vs (48.9±3.1) mmHg (1 mmHg=0.133 kPa), P<0.001]. Conclusion: HFNO combined with early extubation can significantly reduce the incidence of RAE in children undergoing adenoid-tonsillectomy during the emergence from general anesthesia.

Abstract
Objectives: To analyze the type and distribution characteristics of human papillomavirus (HPV) infection along with cervical cytology in middle-aged and elderly women in Guangxi and to provide a basis for the prevention and treatment of cervical cancer in elderly women. Methods: 21 subtypes of HPV and cervical cytology of women over 45-year-old visiting the First Affiliated Hospital of Guangxi Medical University from January 2019 to December 2020 were collected. They were divided into two groups by age, 45-64 years group and over 65 years group. The HPV, HR-HPV, and multiple HPV infection prevalence were analyzed, as well as HPV genotypes, the age distribution of HPV infection rate, and cervical cytology. Results: A total of 6 657 eligible women were included. 6 238 women were in the 45-64 years group, with a HPV prevalence about 20.86% (1 301), while 419 women were in the over 65 years group, with a HPV prevalence about 32.94% (138). The age-associated HPV and HR-HPV prevalence increased with the age, peaking at the age group of 70-74 years (P<0.001). The most prevalent genotype was HPV52, and the infection rate was 5.3% (353), followed by HPV16 and HPV 58, about 4.63% (308) and 3.08% (205) respectively. The majority cytology of HPV-positive middle-aged and elderly women was normal. 8.70% (88) of them were ASC-US, 6.52% (66) for HSIL, 4.55% (46) for LSIL, and 2.96% (30) for ASC-H, and 0.10% (1) for SCC. Compared to middle-aged women, elderly women had a lower negative cytology rate, 69.79% (67) vs. 77.95% (714), but a higher HSIL rate, 13.54% (13) vs. 5.79% (53) (P<0.05). Conclusions: HPV and HR-HPV prevalence of elderly women in a medical center of Guangxi are higher than those of middle-aged women. The most prevalent genotype is HPV16 in elderly women, followed by HPV52 and HPV58.

Abstract
Objective: To screen the differential methylation sites, genes and pathways of air pollution fine particles (PM(2.5)) on human bronchial epithelial (HBE) cells by methylation chip and bioinformation technology, so as to provide scientific basis for further study of the toxicological mechanism of PM(2.5) on HBE cells. Methods: In August 2020, HBE cells were infected with 10 μg/ml and 50 μg/ml PM(2.5) aqueous solution for 24 h, namely PM(2.5) 10 μg/ml exposure group (low dose group) and PM(2.5) 50 μg/ml exposure group (high dose group) ; uninfected HBE cells were used as control group. The DNA fragments were hybridized with the chip, the chip scanned and read the data, analyzed the data, screened the differential methylation sites, carried out GO analysis and KEGG analysis of the differential methylation sites, and analyzed the interaction relationship of the overall differential methylation sites by functional epigenetic modules (FEMs). Results: Compared with the control group, 127 differential methylation sites were screened in the low-dose group, including 89 genes, including 55 sites with increased methylation level and 72 sites with decreased methylation level. The differential methylation sites were mainly concentrated in the Body region and UTR region. Compared with the control group, 238 differential methylation sites were screened in the high-dose group, including 168 genes, of which 127 sites had increased methylation level and 111 sites had decreased methylation level. The differential heterotopic sites were mainly concentrated in the Body region and UTR region. Through FEMs analysis, 8 genes with the most interaction were screened, of which 6 genes had significant changes in methylation level. MALT1 gene related to apoptosis was found in the heterotopic site of methylation difference in low-dose group; PIK3CA and ARID1A genes related to carcinogenesis were found in the heterotopic sites of methylation difference in high-dose group; TNF genes related to tumor inhibition were found in the results of FEMs analysis. Conclusion: After PM(2.5) exposure to HBE cells, the DNA methylation level is significantly changed, and genes related to apoptosis and carcinogenesis are screened out, suggesting that the carcinogenic mutagenic effect of PM(2.5) may be related to DNA methylation.

Abstract
Golgi protein 73 (GP73) is a transmembrane protein on the Golgi apparatus and can be cut and released into the blood. In recent years, an increasing number of clinical studies have shown that the elevated serum GP73 level is closely related to liver diseases. And thus GP73 is expected to be used as a new serum marker for assessing progress of chronic liver diseases. Herein, the clinical application of serum GP73 in chronic hepatitis, liver fibrosis, liver cirrhosis and hepatocellular carcinoma with different etiologies was reviewed based on available literatures; and a research outlook in this field is made.

Abstract
Hepatitis C virus (HCV) RNA can be cleared from the blood circulation by direct antiviral treatment to achieve sustained virologic response (SVR). Studies have shown that SVR after direct antiviral therapy can reduce the incidence of hepatocellular carcinoma; however, monitoring for hepatocellular carcinoma is still needed. This review briefly summarizes and discusses the existing studies on the possible causes of hepatitis C secondary to HCC after antiviral therapy, which is mainly divided into epigenetic alterations and abnormal DNA methylation, HCV-related cirrhosis and abnormal DNA amplification, HBV reactivation, several aspects of occult HCV infection, and the effect of direct antiviral treatment on hepatocellular carcinoma recurrence. In few cases, direct antiviral treatment cannot completely prevent the occurrence and recurrence of hepatitis C-related hepatocellular carcinoma. Therefore, its mechanism needs to be studied and explored, and clinicians should also approach it with caution.

Abstract
Objective: To evaluate the effectiveness and safety of Pul-Stent as the treatment of postoperative branch pulmonary artery stenosis in children with congenital heart disease. Methods: This was a retrospective study. Thirty-three patients who underwent Pul-Stent implantation in Shanghai Children's Medical Center due to postoperative residual pulmonary artery stenosis from August 2014 to June 2015 were included. The immediate curative effect, follow-up and complications of Pul-Stent implantation were assessed. Comparisons between groups were performed with unpaired Student t test. Results: Pul-Stent implantation of 33 patients (19 males and 14 females) were performed successfully. Thirty-one patients underwent percutaneous stenting, and 2 patients underwent hybrid stenting. A total of 35 Pul-Stents were implanted (19 of model small, 15 of model medium and one of model large), 23 stents were planted in the proximal left pulmonary artery and 12 stents were in the proximal right pulmonary artery. The initial diameter of dilation balloon ranged from 6 to 16 mm, and the long sheath of percutaneous implantation ranged from 8 to 10 F in 29 patients (29/31, 94%). After stenting, the diameter of the narrowest segment of pulmonary artery increased from (4.0±1.7) mm to (9.1±2.1) mm in all patients (t=-21.60, P<0.001). The pressure gradient at the stenosis in 26 patients after biventricular correction decreased from (30.5±12.3) mmHg (1 mmHg=0.133 kPa) to (9.9±9.6) mmHg (t=12.92, P<0.001), and the right ventricular to aortic pressure ratio decreased from 0.57±0.14 to 0.44±0.12 (t=7.44, P<0.001). The pressure of the superior vena cava after stenting in 5 patients after cavopulmonary anastomosis decreased from (17.0±1.9) mmHg to (14.0±0.7) mmHg (t=2.86, P=0.046). Two patients died during reoperation for repairing other cardiac malformations. The remaining 31 patients were clinically stable during the follow-up period of (5.3±1.6) years, and one stent fracture was found on chest X-ray. Cardiac catheterization reexaminations in 16 patients showed that restenosis was found in one stent, while stent position and patency were satisfactory in the remaining stents. Nine children underwent post-dilation without stent fracture, displacement or aneurysm formation. Cardiac tomography showed no stent stenosis, fracture observed, or significant change in diameter of the stent in 8 patients. The inner diameter and pulmonary blood perfusion could not be accurately evaluated due to artifacts by cardiac magnetic resonance imaging in 4 patients. Conclusions: Pul-Stent has good compliance and adequate radial strength, and can dilate further over time to accommodate for somatic growth. It performs safely and effectively in treating post-operative branch pulmonary artery stenosis in children.

Abstract
Objective: To explore the effects of K-ras gene on the expressions of oncogenes and cancer suppressor genes in human bronchial epithelial (HBE) cells which were exposed to PM(2.5). Methods: According to the mRNA sequence of K-ras gene provided by GenBank in September 2019, interference sequences were designed and synthesized, and the recombinant lentiviral vector was transfected into HBE cell to construct the K-ras gene-silenced cells. HBE cells and K-ras gene-silenced cells were exposed to 10 μg/ml, 50 μg/ml PM(2.5) suspension and 10 μmol/L Cr(6+). Real-time fluorescent quantitative PCR was used to detect the mRNA expression levels of c-myc, c-fos, N-ras, cyclin-D1, p16 and p53 genes, the expression levels of p53 and c-myc proteins were detected by Western blot. Results: In K-ras silenced cell group, K-ras mRNA expression level decreased (80.5%±3.6%) and K-ras protein level decreased (58.9%±4.7%) when compared with the control group (P<0.01) . Compared with the correspoding cell control group without exposure, the mRNA expression levels of c-myc, c-fos, N-ras and cyclin-D1 genes in HBE cell group exposed to different concentrations of PM(2.5), K-ras silenced cell group exposed to different concentrations of PM(2.5), HBE cell group exposed to 10 μmol/L Cr(6+) and K-ras silenced cell group exposed to 10 μmol/L Cr(6+) were increased, the mRNA expressions of p16 and p53 genes were decreased (P<0.01) . Compared with HBE cell group exposed to 10 μg/ml PM(2.5), the mRNA expressions of c-myc, c-fos and p16 genes in K-ras silenced cells exposed to 10 μg/ml PM(2.5) were decreased, and the p53 mRNA level was increased (P<0.01) . Compared with HBE cell group exposed to 50 μg/ml PM(2.5), the mRNA expression levels of c-fos, N-ras, cyclin-D1, p16 and p53 genes in K-ras silenced cell group exposed to 50 μg/ml PM(2.5) were decreased (P<0.01) . Compared with the HBE cell group without exposure, c-myc protein increased and p53 protein decreased in HBE cells exposed to 50 μg/ml PM(2.5) (P<0.05) . Compared with the K-ras silenced cell group without exposure, c-myc protein increased in K-ras silenced cells exposed to 50 μg/ml PM(2.5) (P<0.05) . Conclusion: PM(2.5) can increase the expression levels of oncogenes in HBE cells, and K-ras gene silencing can inhibit the expression levels of oncogenes in HBE cells treated with PM(2.5).

Abstract
Epstein-Barr virus (EBV) infection is closely associated to liver injury with diverse clinical features in adolescents and adults. It is often manifested as infectious mononucleosis syndrome, sometimes causing self-limited acute hepatitis, with mild to moderate elevation of liver transaminases, and relative increase in age-related conditions. EBV infection can also cause cholestatic hepatitis, with elevated alkaline phosphatase and γ-glutamyltransferase as the main manifestations, accompanied by varying degrees of jaundice. A small number of patients with severe EBV infection may experience liver failure, and if left untreated in time, it may lead to high mortality. In addition, EBV infection is also associated with chronic hepatitis, liver cirrhosis, autoimmune liver disease, etc.

Abstract
Higher-order topological insulators, as newly found non-trivial materials and structures, possess topological phases beyond the conventional bulk-boundary correspondence. In previous studies, in-gap boundary states such as the corner states were regarded as conclusive evidence for the emergence of higher-order topological insulators. Here, we present an experimental observation of a photonic higher-order topological insulator with corner states embedded into the bulk spectrum, denoted as the higher-order topological bound states in the continuum. Especially, we propose and experimentally demonstrate a new way to identify topological corner states by exciting them separately from the bulk states with photonic quantum superposition states. Our results extend the topological bound states in the continuum into higher-order cases, providing an unprecedented mechanism to achieve robust and localized states in a bulk spectrum. More importantly, our experiments exhibit the advantage of using the time evolution of quantum superposition states to identify topological corner modes, which may shed light on future exploration between quantum dynamics and higher-order topological photonics.

Abstract
目的 筛选并分析与弥漫大B细胞淋巴瘤(DLBCL)预后相关的免疫表型,探究其预后价值。 方法 选取天津医科大学肿瘤医院2011年1月至2016年12月收治的163例DLBCL患者,免疫组织化学染色检测DLBCL常见免疫表型,COX模型探索独立于国际预后指数(IPI)影响总生存(OS)与无进展生存(PFS)的免疫表型,并分析其两两联合表达对预后的影响。 结果 多因素分析显示BCL6阴性(PFS:HR=1.652,95% CI 1.030~2.649,P=0.037)、P53阳性(OS:HR=1.842,95% CI 1.008~3.367,P=0.047)、BCL2强阳性(OS:HR=2.102,95%CI 1.249~3.537,P=0.005;PFS:HR=2.126,95% CI 1.312~3.443,P=0.002)是DLBCL中独立于IPI的预后不良因素。亚组分析显示,在年龄≤60岁组患者中BCL6阴性(PFS:HR=2.042,95%CI 1.021~4.081,P=0.043)、P53阳性(OS:HR=3.069,95% CI 1.244~7.569,P=0.015)和BCL2强阳性(OS:HR=2.433,95% CI 1.165~5.082,P=0.018;PFS:HR=3.209,95%CI 1.606~6.410,P=0.001)对预后影响显著;在IPI 0~2分亚组患者中,BCL6阴性(OS:HR=2.467,95%CI 1.322~4.604,P=0.005;PFS:HR=2.248,95%CI 1.275~3.965,P=0.005)和BCL2强阳性(PFS:HR=2.045,95%CI 1.119~3.735,P=0.020)对预后影响显著。BCL6和BCL2强阳性的联合表达与DLBCL的预后相关(P=0.005和P<0.001),BCL6阳性/BCL2非强阳性(86例)预后最好[3年OS率(71.6±4.9)%,3年PFS率(67.0±5.1)%],BCL6阴性/BCL2强阳性(10例)预后最差[3年OS率(20.0±12.6)%,3年PFS率(10.0±9.5)%];BCL6、P53的联合表达与DLBCL的预后差异无统计学意义(P=0.061和P=0.089),但生存曲线显示BCL6阳性/P53阴性的病例(98例)预后较好[3年OS率(70.6±4.7)%,3年PFS率(64.6±4.9)%];BCL2强阳性、P53的联合表达与DLBCL的预后显著相关(P<0.001和P<0.001),BCL2强阳性/P53阳性的病例(5例)预后最差(3年OS率和PFS率均为0);无论BCL6与P53表达如何,BCL2强阳性的病例预后均比非强阳性病例差。 结论 BCL6阴性、P53阳性、BCL2强阳性三种免疫表型单独及联合表达对DLBCL尤其是年龄≤60岁和IPI 0~2分患者的预后预测具有一定价值。

Abstract
CD63 is a member of the four-transmembrane-domain protein superfamily and is the first characterized tetraspanin protein. In the present study, we cloned the common carp (Cyprinus Carpio) CD63 (ccCD63) sequence and found that the ccCD63 ORF contained 711 bp and encoded a protein of 236 amino acids. Homology analysis revealed that the complete ccCD63 sequence had 84.08% amino acid similarity to CD63 of Sinocyclocheilus anshuiensis. Subcellular localization analysis revealed that ccCD63 was localized in the cytoplasm. Quantitative real-time PCR (qRT-PCR) analysis indicated that ccCD63 was expressed in the gill, intestine, liver, spleen, brain and kidney, with higher expression in spleen and brain tissues than in the other examined tissues. After koi herpesvirus (KHV) infection, these tissues exhibited various expression levels of ccCD63. The expression level was the lowest in the liver and highest in the brain; the expression level in the brain was 8.7-fold higher than that in the liver. Furthermore, knockdown of ccCD63 promoted KHV infection. Moreover, ccCD63 was correlated with the regulation of RIG-I/MAVS/TRAF3/TBK1/IRF3 and may be involved in the antiviral response through the RIG-I viral recognition signalling pathway in a TRAF3/TBK1-dependent manner. Taken together, our results suggested that ccCD63 upregulated the interaction of KHV with the host immune system and suppressed the dissemination of KHV.

Abstract
Objective: To summarize the clinical and pathological features of intravascular NK and T cell lymphoma for better understanding of such disease to reduce misdiagnosis and miss-diagnosis. Methods: Clinical and pathological features were analyzed retrospectively in one case of intravascular peripheral T-cell lymphoma, not otherwise specified (IVPTCL, NOS) , with literatures review. Results: The case presented in this study was a 66-year-old man. PET/CT scan showed multiple lymph nodes enlargement throughout the body. Normal lymph node structure could not be observed by tissue biopsy, while lymph follicles were partially disrupted. High-power light microscope revealed a large number of blood vessels with diffuse proliferation and dilation, where atypical lymphoid cell mass was restricted in the lumen and partially infiltrated the large blood vessel wall. These tumor cells were medium to large with moderate cytoplasm. The nucleus was irregular, single or multiple nucleoli could be seen, chromatin was condensed, some were empty and bright, and mitotic figures could be seen. Immunohistochemical staining showed that the neoplastic cells were positive for expression of CD3, CD43, CD8, GrB, TIA-1 and perforin. EBER in situ hybridization result was negative. Polymerase chain reaction test identified a clonal gene rearrangement of T-cell receptor γ. The patient was treated with CHOP in combination with chidamide, but died of infection and cardiopulmonary failure within 2 months. 56 cases of intravascular NK/T cell lymphoma with definite classification were collected from relevant literatures, including 47 cases with nasal type of extranodal NK/T cell lymphoma (27 were male and 20 were female) , 8 cases with anaplastic large cell lymphoma (3 males and 5 females) , and only one case with de nova IVPTCL, NOS in brain. We report the second case of IVPTCL,NOS, and notably originated from lymph node for the first time. Conclusions: Intravascular NK/T cell lymphoma is a highly aggressive disease with no effective treatment at present. Involvement of Lymph node has rarely been reported, and further studies on more cases are necessary.

Abstract
Objective: To study the risk factors associated with the hospital survival rate of elder patients with acute respiratory distress syndrome (ARDS) in Medical/Respiratory Intensive Care Units (MICUs/RICUs) by evaluating the prognosis, and therefore to provide insight into patient treatment strategy. Methods: Twenty MICUs/RICUs of 19 general hospitals in mainland China participated in the multicenter prospective cohort study carried out from Mar 1st, 2016 to Feb 28th, 2018. Patients who met the criteria of Berlin ARDS and older than 65 years were recruited. Baseline data, risk factors of ARDS, ventilator setup and prognosis data were collected from all patients. Univariant and multivariant regression analysis were conducted to analyze the factors associated with the prognosis. Results: 170 elder ARDS patients (age≥65 years) met the Berlin ARDS criteria, among whom 8.8% (15/170), 42.9% (73/170) and 48.2% (82/170) patients had mild, moderate and severe ARDS, respectively. The most common predisposing factor for elder ARDS was pneumonia, which was present in 134 patients (78.8%). 37.6% (64/170) patients were treated with noninvasive mechanical ventilation (NIV), but 43.8% (28/64) cases experienced treatment failure. 76.5% (130/170) patients were treated with invasive mechanical ventilation. All patients 80 years or older were given invasive mechanical ventilation. 51.8% (88/170) cases had complications of non-pulmonary organ failure. 61.8% (105/170) patients deceased during hospital stay. Multivariant logistic analysis showed that the independent risk factors for hospital survival rate in elder patients with ARDS were SOFA score (P=0.030, RR=0.725, 95% CI 0.543-0.969), oxygen index after 24 hours of ARDS diagnosis (P=0.030, RR=0.196, 95% CI 0.045-0.853), accumulated fluid balance within 7 days after diagnosis of ARDS (P=0.026, RR=1.000, 95% CI 1.000-1.000) and shock (P=0.034, RR=0.140, 95% CI 0.023-0.863). Conclusion: Among 20 ICUs, the high mortality rate of elder patients with ARDS was correlated with higher 24 hour SOFA score, lower 24 hour oxygen index after ARDS diagnosis, more positive fluid balance within 7 days and concomitant shock. The conservative fluid strategy within 7 days of ARDS diagnosis may benefit the elder ARDS patients.

Abstract
Adipocyte fatty-acid binding protein (A-FABP) plays a central role in many aspects of metabolic diseases. It is an important target in drug design for treatment of FABP-related diseases. In this study, molecular dynamics (MD) simulations followed by calculations of molecular mechanics generalized Born surface area (MM-GBSA) and principal components analysis (PCA) were implemented to decipher molecular mechanism correlating with binding of inhibitors 57Q, 57P and L96 to A-FABP. The results show that van der Waals interactions are the leading factors to control associations of 57Q, 57P, and L96 with A-FABP, which reveals an energetic basis for designing of clinically available inhibitors towards A-FABP. The information from PCA and cross-correlation analysis rationally unveils that inhibitor bindings affect conformational changes of A-FABP and change relative movements between residues. Decomposition of binding affinity into contributions of individual residues not only detects hot spots of inhibitor/A-FABP binding but also shows that polar interactions of the positively charged residue Arg126 with three inhibitors provide a significant contribution for stabilization of the inhibitor/A-FABP bindings. Furthermore, the binding strength of L96 to residues Ser55, Phe57 and Lys58 are stronger than that of inhibitors 57Q and 57P to these residues.

Abstract
We investigated the effects of potassium-releasing bacteria on physiological and bioche-mical characteristics of Lycium barbarum (Cultivar Ningqi 1) under salt stress, with an experiment with treatments following randomized block design. The treatments included control (CK), 100 mmol·L-1 NaCl stress (NaCl), 100 mmol·L-1NaCl stress+KSBGY01 bacteria (NaCl-M1), 100 mmol·L-1NaCl stress+KSBGY02 bacteria (NaCl-M2), and 100 mmol·L-1NaCl stress+KSBGY01+KSBGY02 (NaCl-M3). We measued chlorophyll content, polyphenol content, superoxide anion (O2-·) content, hydrogen peroxide (H2O2) content, soluble sugar content, antioxidant enzyme activity and sucrose metabolic enzyme activity of Lycium barbarum seedlings. Results showed that the presence of potassium bacteria increased the values of flavonoids (FLAV), fluorescence excitation than anthocyanins relative index (FERARI), anthocyanins (ANTH-RB), nitrogen balance index (NBI-G), decreased the contents of O2-· and H2O2, and improved soluble sugar content, catalase (CAT) activity, sucrose phosphate synthase (SPS) activity, sucrose synthase (SS) activity and invertase (INV) activity of leaves in Lycium barbarum seedlings under salt stress. Among all the treatments, the highest values of ANTH-RB and NBI-G, soluble sugar content, and activities of CAT, SPS, SS, and INV presented in NaCl-M2 treatment, the highest values of SPAD, FLAV, and FERARI presented in NaCl-M3 treatment, the highest activity of superoxide dismutase (SOD) presented in NaCl-M1 treatment, the highest activity of glutathione peroxidase (GSH-Px) presented in NaCl treatment, and the highest peroxisome (POD) activity presented in CK. The 14 significant physiological and biochemical indicators in the leaves of L. barbarum seedling were analyzed by grey system correlation degree method. Our results suggested that the weighted correlation degree of phy-siological and biochemical indices of L. barbarum inoculated potassium-solubilizing bacteria was higher than that under CK and NaCl treatments. The highest weighted correlation was observed in NaCl-M2 treatment. Therefore, adding KSBGY02 potassium-solubilizing bacteria could alleviate the salt stress for L. barbarum seedlings.

Abstract
Introduction The present study aimed to investigate the differences in the proteomic expression between uncomplicated parapneumonic pleural effusion (UPPE) and complicated parapneumonic pleural effusion (CPPE). Material and methods There were 10 patients with UPPE and 10 patients with CPPE. These patients were combined due to the complication of pleural effusion and further divided into group A and group B. An LC-MS analysis was conducted with the extraction of high-abundance proteins, and proteins with 1.5-fold or higher difference multiples were identified as differential proteins. Then, gene ontology (GO) and KEGG analyses were conducted on the differential proteins between the groups. Results Compared with the UPPE group, there were 38 upregulated proteins and 29 downregulated proteins in the CPPE group. The GO analysis revealed that the CPPE group had enhanced expressions in monosaccharide biosynthesis, glucose catabolism, fructose-6-phosphate glycolysis, glucose-6-phosphate glycolysis, and NADH regeneration as well as reduced expressions in fibrinogen complexes, protein polymerization, and coagulation. Moreover, the KEGG analysis showed that the CPPE group had enhanced expressions in amino acid synthesis, the HIF-1 signalling pathway, and glycolysis/glycoisogenesis and decreased expressions in platelet activation and complement activation. Conclusions In pleural effusion in patients with CPPE, there are enhanced expressions of proteins concerning glucose and amino acid metabolism, NADH regeneration, and HIF-1 signalling pathways together with decreased expressions of proteins concerning protein polymerization, blood coagulation, platelet activation, and complement activation.

Abstract
Quantum computation promises intrinsically parallel information processing capacity by harnessing the superposition and entanglement of quantum states. However, it is still challenging to realize universal quantum computation due that the reliability and scalability are limited by unavoidable noises on qubits. Nontrivial topological properties like quantum Hall phases are found capable of offering protection, but require stringent conditions of topological band gaps and broken time-reversal symmetry. Here, we propose and experimentally demonstrate a symmetry-induced error filtering scheme, showing a more general role of geometry in protection mechanism and applications. We encode qubits in a superposition of two spatial modes on a photonic Lieb lattice. The geometric symmetry endows the system with topological properties featuring a flat band touching, leading to distinctive transmission behaviors of π-phase qubits and 0-phase qubits. The geometry exhibits a significant effect on filtering phase errors, which also enables it to monitor phase deviations in real time. The symmetry-induced error filtering can be a key element for encoding and protecting quantum states, suggesting an emerging field of symmetry-protected universal quantum computation and noisy intermediate-scale quantum technologies.

Abstract
This study mainly investigated the distribution characteristics and risk assessment of 14 antibiotics in typical marine aquaculture farms surrounding the Bohai Sea. The effects of various culture modes (outdoor pond culture, recirculating water culture, greenhouse pond culture, raft culture, cage culture and bottom sowing culture), and diverse cultured organism species such as fish (grouper, bass, pike and turbot), mollusk (oyster, scallop, conch and mussel) and sea cucumber on the distribution of antibiotics in different mariculture pond matrices (seawater, sediment/biofilm and organism) were studied. In addition, antibiotic pollution levels in various matrices (water, sediment, organism and feed) from different mariculture areas surrounding the Bohai Sea and the Yellow Sea were compared. The biofilm on the inner wall of greenhouse pond was more capable of accumulating antibiotics than the biofilm attached to the rope for raft culture and net for cage culture, and other culture sediments. The antibiotic concentration level in the culture matrices (water, sediment/biofilm and organism) was the highest under greenhouse pond culture mode, and that under the industrial recirculating water culture mode was the lowest. Antibiotic concentration in culture matrices of fish ponds was higher than that of sea cucumber ponds and mollusk ponds. The levels of antibiotics in water and sediment from marine aquaculture farms in Laizhou (Bohai Sea coast) were higher than those in Haiyang and Jimo (Yellow Sea coast). Enrofloxacin in turbot might cause considerable harm to human health, and the risk of antibiotics in other seafood could be ignored. Antibiotic ecological risks and resistance risks were generally low in water. Fluoroquinolones posed medium to high ecological risks in the natural receiving water around the mariculture farm. Trimethoprim and enrofloxacin showed relatively high antibiotic resistance risks in mariculture water and natural water, which might exert selective pressure on the bacterial community in the environment.

Abstract
Liver cirrhosis is the final stage of many chronic liver diseases, and is still a heavy disease burden. The proportion of liver cirrhosis caused by the hepatitis B virus is declining, while that caused by the non-alcoholic fatty liver disease (metabolic-associated fatty liver disease) is rising. Several predictive models and techniques such as transient elastography have been used for the early non-invasive evaluation of liver cirrhosis. Effective etiological treatment and complication management are the possible key to reverse and recompense liver function during liver cirrhosis treatment. In recent years, the effectiveness and availability of anti-hepatitis B and C virus drugs have been significantly improved, which provides the basis for effective etiological treatment of liver cirrhosis. However, there is still a lack of etiological treatment measures for non-alcoholic fatty liver disease. Therefore, in addition to focusing on common complications, we should also manage "rare" complications. This article reviews the changes in epidemiological characteristics, the update of the natural history concepts, diagnostic evaluation methods, and the treatment measures for liver cirrhosis.

Abstract
The implementation of quantum information technologies requires the development of integrated quantum chips. Femtosecond laser direct writing (FLDW) waveguides and superconducting nanowire single-photon detectors (SNSPDs) have been widely applied in integrated quantum photonic circuits. In this work, a novel FLDW waveguide-coupled SNSPD was designed and realized by integrating FLDW waveguides and conventional SNSPDs together. Through a COMSOL simulation, a waveguide end face-nanowire optical coupling structure was designed and verified. The simulation results showed that the FLDW waveguide-coupled SNSPD device, which had a target wavelength of 780 nm, can achieve 87% optical absorption. Then the preparation process of the FLDW waveguide-coupled SNSPD device was developed, and the fabricated device achieved a system detection efficiency of 1.7% at 10 Hz dark count rate. Overall, this method provides a feasible single-photon detector solution for future on-chip integrated quantum photonic experiments and applications.

Abstract
PURPOSE Adenomyosis is a diffuse or localized disease. Our previous study has indicated that tanshinone IIA (TSIIA) inhibits the proliferation, migration, and induces apoptosis of ectopic endometrial stromal cells (EESCs) of adenomyosis. However, the complex molecular mechanism of TSIIA in adenomyosis remains unclear. The objective of this study was to explore the complex molecular mechanism of TSIIA on EESCs. METHODS In our present study, we used the proteomics approach iTRAQ (isobaric tags for relative and absolute quantitation) combined with LC-MS/MS (liquid chromatography-mass spectrometry) to investigate changes in the protein profile of EESCs treated with TSIIA. Differential proteins were analyzed by employing bioinformatics tools and the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. In TSIIA treated EESCs, the protein expression levels of TNFRSF10D, PLEKHM1, FECH, and TPM1A were detected by western blotting. RESULTS Quantitative results revealed 267 significantly differential proteins in TSIIA pretreated EESCs. Gene Ontology (GO) analysis presented an overview of dysregulated proteins in the biological process (BP), cell component (CC), and molecular function (MF) categories. Interestingly, we observed that differential proteins in the extracellular matrix (ECM)-receptor interaction pathway and estrogen signaling pathway were all involved in the focal adhesion pathway, which plays essential roles in the TSIIA-mediated inhibition of EESC proliferation and migration. Furthermore, some significantly differential proteins, which may be potential targets for the treatment of adenomyosis in the future, were validated by western blotting. CONCLUSIONS Our study provides a useful method to detect the detailed mechanism underlying the efficacy of TSIIA on EESCs.

Abstract
OBJECTIVE To investigate the prevalence of Spirometra mansoni infections in hosts in Jiangsu Province, so as to provide the scientific basis for the management of sparganosis mansoni. METHODS From 2018 to 2019, nine counties (cities, districts) were randomly selected from Jiangsu Province as the survey sites, and 100 healthy individuals were randomly selected to perform the serological test of S. mansoni infections and the detection of S. mansoni eggs. The procercoids were detected in the intermediate host Cyclops, and the S. mansoni eggs were identified in the stool samples of the definitive hosts cats and dogs. RESULTS The prevalence of S. mansoni human infections was 0 (0/900) in the 9 survey sites of Jiangsu Province, and the sero-prevalence of the specific IgG antibody against S. mansoni was 1.22% (11/900). The positive rate of procercoids was 0.33% (3/900) in Cyclops. In addition, the S. mansoni egg-positive rate was 1.48% (2/135) in cats and dogs. CONCLUSIONS Sparganosis mansoni is prevalent in Jiangsu Province. Health education pertaining to the damages of sparganosis mansoni and the route of S. mansoni infections should be improved.

Abstract
To evaluate the association between ambient air pollution and hyperuricemia, we prospectively followed 1748 traffic police officers without hyperuricemia at baseline (2009-2014) from 11 districts in Guangzhou, China. We calculated six-year average PM10, SO2 and NO2 concentrations using data collected from air monitoring stations. The hazard ratios for hyperuricemia per 10 µg/m3 increase in air pollutants were 1.46 (95% CI: 1.28-1.68) for PM10, 1.23 (95% CI: 1.00-1.51) for SO2, and 1.43 (95% CI: 1.26-1.61) for NO2. We also identified changes in the ratio of serum uric acid to serum creatinine concentrations (ua/cre) per 10 µg/m3 increase in air pollutants as 11.54% (95% CI: 8.14%-14.93%) higher for PM10, 5.09% (95% CI: 2.76%-7.42%) higher for SO2, and 5.13% (95% CI: 2.35%-7.92%) higher for NO2, respectively. Long-term exposure to ambient air pollution was associated with a higher incidence of hyperuricemia and an increase in ua/cre among traffic police officers.

Abstract
Chronic hepatitis B virus (HBV) infection remains a major world public health problem. Current guidelines of chronic hepatitis B (CHB) suggest the clinical cure as the ideal thearapeutic goal. Although the optimization of the existing antiviral treatment can make some patients achieve clinical cure, but for most patients with chronic hepatitis B, it is difficult to achieve clinical cure according to the existing antiviral treatment plan. The medical community has begun to work together to seek new treatment strategies, especially the immune intervention measures aimed at restoring the immune response in the liver microenvironment. Notably, immune antiviral response plays a crucial role in HBV clearance, and the clinical cure of chronic hepatitis B is finally achieved through the optimized combination of antiviral and immunomodulatory drugs.

Abstract
Objective: To study the effect of p38 mitogen-activated protein kinase (MAPK) gene silencing on expression of apoptotic genes and oncogenes in hepatocytes treated with PM(2.5). Methods: From June to September 2019, according to the p38MAPK gene mRNA sequence provided by GenBank, three interfering sequences were designed and synthesized, ligated into PLVX-shRNA2-puro after annealing, and the recombinant lentiviral vector was transfected into L02 hepatocytes. The p38MAPK silencing cells were identified by real-time fluorescent quantitative PCR and western blotting. The normal L02 cells and p38MAPK silencing cells were treated with 50 μg/mL PM(2.5) water soluble solution, 10 μmol/L positive control Cr(6+), and a blank control group was set up, the treatment time was 24 h. The mRNA levels of oncogenes (c-fos, c-myc, k-ras) , tumor suppressor gene (p53) and apoptotic genes (Caspase-3, Caspase-8, Caspase-9) were detected by real-time PCR. The protein levels of oncogenes and apoptotic genes were detected by Western blotting. Results: The expression levels of p38MAPK mRNA and protein in p38MAPK gene silencing cells were significantly lower than those in L02 hepatocytes (P<0.05) , and the p38MAPK gene silencing cell line was successfully constructed. Compared with the blank control group, the expression levels of the oncogenes c-fos, c-myc, k-ras and the apoptosis genes Caspase-3, Caspase-8 and Caspase-9 increased, the expression level of tumor suppressor gene p53 decreased in the L02 hepatocyte group treated with PM(2.5) water soluble matter, and the differences were statistically significant (P<0.05) . Compared with the L02 hepatocytes group treated with PM(2.5) water soluble matter, the expression levels of the oncogenes c-fos, c-myc, k-ras and apoptosis genes Caspase-3, Caspase-8 and Caspase-9 decreased, the expression level of tumor suppressor gene p53 increased in the p38MAPK gene silencing cells group treated with PM(2.5) water soluble matter, and the differences were statistically significant (P<0.05) . Conclusion: PM(2.5) has effects on the expression of oncogenes, tumor suppressor genes and apoptotic genes in L02 hepatocytes, while p38MAPK gene silencing can inhibit the effects of PM(2.5) on L02 hepatocytes.

Abstract
Renal dysfunction is common in patients with decompensated cirrhosis. The types include of prerenal and postrenal, structural kidney disease, interstitial nephritis and functional renal failure, which is related to hemodynamic changes without obvious histopathological changes, the most common of which are acute kidney injury and hepatorenal syndrome. In recent years, there have been updated to some extents in the liver cirrhosis combined with kidney diseases, especially in the definition, classification, pathogenesis, diagnostic criteria, management process of acute kidney injury and hepatorenal syndrome.
