Abstract
Objective: To investigate the epidemiology of hepatitis B virus (HBV) infection in patients with rheumatoid arthritis (RA) in China and its association with RA disease characteristics. Methods: A cross-sectional study. A retrospective study was conducted on RA patients recruited from January 2001 to February 2023 in the Department of Rheumatology and Immunology, Sun Yat-Sen Memorial Hospital. Demographic and clinical data were collected including age, gender, disease duration, active smoking, RA disease activity, physical function, radiographic assessment, serological markers of HBV infection and liver function indicators. According to the status of HBV infection, RA patients were grouped as chronic HBV infection, resolved HBV infection and no HBV infection groups. The distribution of each group and the clinical characteristics of RA patients were analyzed. Results: Among 1 941 RA patients, 1 461 (75.3%) completed HBV screening, including 335 males (22.9%) and 1 126 females (77.1%), with a mean age of (55.4±13.1) years. The prevalence of chronic HBV infection was 10.1%(148/1 461), which was significantly higher in male patients than in females [14.6%(49/335) vs 8.8%(99/1 126), P<0.001], especially among those males born from 1970 to 1979[20.0%(7/35) vs 8.5%(17/201), P=0.037] and 1980-1989 [31.8%(7/22) vs 10.5%(14/133), P=0.007]. Among 148 RA patients with chronic HBV infection, there were 5 cases (3.4%) of chronic hepatitis B, 2 cases (1.4%) of HBV-associated cirrhosis and 1 case (0.7%) of hepatocellular carcinoma. The prevalence of resolved HBV infection was 57.6%(841/1 461). There were 472(32.3%) patients with no HBV infection and 267(56.6%) of them showed negative anti-HBs. Among all RA patients, 15 (1.0%) patients had abnormal liver function, of which 7 cases were drug-induced liver injury, 5 cases were chronic hepatitis B, 2 cases were non-alcoholic fatty liver disease, and 1 case was primary biliary cholangitis. Conclusion: Chronic HBV infection remains a common complication in RA patients in China, the infection rate is 10.1%, and the screening and management of HBV infection should be strengthened in clinical practice.

Abstract
Currently, ultrahigh-nickel layered oxide is one of the most promising cathodes for lithium-ion batteries, with the advantages of high theoretical capacity and low cost. However, some problems in ultrahigh-nickel layered oxides are more serious, such as irreversible structural transformation, particle cracking, and side reactions at the electrode/electrolyte interface, resulting in the fast decay of the discharge capacity and midpoint potential. In this work, La doping is introduced into ultrahigh-nickel layered LiNi0.9Co0.1O2 oxide to improve the cycle stability on both discharge capacity and midpoint potential. As demonstrated, La can be doped successfully into the subsurface of LiNi0.9Co0.1O2 oxide, and the morphology of the oxide microspheres is not changed obviously by La doping. Compared with the pristine sample, the La-doped sample presents improved electrochemical performance, especially good cycle stabilization on both discharge capacity and midpoint potential. In addition, after a long-term cycle, the La-doped sample still maintains a relatively complete spherical morphology. It means that the pillaring effect of La with a large radius is helpful in accommodating the volume change caused by the insertion/extraction of Li ions, thus easing the anisotropic stress accumulation and microcrack growth inside the microspheres of the La-doped sample.

Abstract
Objective: To investigate the peripheral blood inflammatory markers including white blood cell count (WBC), monocytes, neutrophils, lymphocytes, platelets, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), high-density lipoprotein(HDL-C), low-density lipoprotein and fibrinogen (FIB) in Ménière's disease (MD) patients with and without migraine, and to explore the relationship between the inflammatory response with MD and migraine. Methods: The general physical condition, clinical manifestations, pure-tone audiometry, and peripheral blood inflammatory markers of 92 unilateral MD patients who were hospitalized in Peking University People's Hospital for surgical treatment from January 2017 to January 2021 were continuously collected. Meanwhile, 50 healthy controls matched with age and sex were included, and their general physical conditions and peripheral blood inflammatory markers were also collected. This study consisted of two parts. First, the differences in epidemical characteristics and peripheral blood inflammatory markers between MD patients and healthy controls were compared by univariate analysis. Second, all 92 MD patients were divided into two subgroups according to whether they were accompanied by migraine. The clinical characteristics and peripheral blood inflammatory markers of MD patients with and without migraine were compared by univariate analysis. Thereafter, binary Logistic regression was used to analyze the related factors of whether MD patients were accompanied with migraine. Results: Compared with the healthy control group, the peripheral blood WBC, neutrophils and FIB of MD patients were significantly increased (all P<0.05). Compared with MD patients without migraine, MD patients with migraine had higher female prevalence, longer disease history, lower low-frequency hearing threshold, higher frequency of vertigo attacks and higher HDL-C levels (all P<0.05), meanwhile, female, frequency of vestibular attacks and HDL-C were independent related factors of whether MD patients were accompanied with migraine. Conclusion: The occurrence of MD and migraine may be related to the inflammatory response. The level of anti-inflammatory factors in the blood of MD patients with migraine are higher, suggesting that the inflammatory response status of MD patients with and without migraine is different.

Abstract
The objective of this study was to investigate the mechanism of Toll-like receptor (TLR4)- mediated dendritic cell (DC) immune against Cryptosporidium parvum infection. C. parvum sporozoites were labeled with 5,6-carboxyfluorescein diacetate succinimidyl ester. Murine bone marrow-derived DCs were isolated, and divided into TLR4 antibody blocking (TAB; infected with 2 × 105 labeled sporozoites and 0.5 μg TLR4 blocking antibody), TLR4 antibody unblocking (TAU; infected with 2 × 105 labeled sporozoites), and blank control (BC; with 1.5 mL Roswell Park Memorial Institute 1640 medium) groups. The adhesion of Cryptosporidium sporozoites to DCs and CD11c+ levels were examined by fluorescence microscopy and flow cytometry. Male KM mice were orally injected with C. parvum. The proliferation of T lymphocytes in spleen, expression of cytokines in peripheral blood, and TLR4 distribution features in different organs were further determined by immunohistochemistry. A significantly higher expression of CD11c+ and higher C. parvum sporozoite adhesion were found in the TAU group compared with other groups. The expression of CD4+CD8- /CD8+CD4- in the spleen were obviously differences between the TAB and TAU groups. The expression of TLR4, interleukin IL-4, IL-12, IL-18 and IFN-γ improved in the TAU group compared with TAB group. Higher expression of TLR4 was detected in the lymph nodes of mice in the TAU group, with pathological changes in the small intestine. Hence, TLR4 could mediate DCs to recognize C. parvum, inducing Th1 immune reaction to control C. parvum infection.

Abstract
Objective: To investigate the methods for qualitative pathological assessment of dynamic changes in liver fibrosis/cirrhosis after antiviral therapy in patients with chronic hepatitis B (CHB), since antiviral therapy can partially reverse liver fibrosis and cirrhosis caused by hepatitis B and semi-quantitative, rather than qualitative, pathological assessment is often used for the research on liver fibrosis regression. Methods: Previously untreated CHB patients with liver fibrosis and cirrhosis were enrolled, and liver biopsy was performed before treatment and at 78 weeks after the antiviral therapy based on entecavir. The follow-up assessment was performed once every half a year. Based on the proportion of different types of fibrous septum, we put forward the new qualitative criteria called P-I-R classification (predominantly progressive, predominantly regressive, and indeterminate) for evaluating dynamic changes in liver fibrosis. This classification or Ishak fibrosis stage was used to evaluate the change in liver fibrosis after treatment and Ishak liver inflammation score was used to evaluate the change in liver inflammation after treatment. Results: A total of 112 CHB patients who underwent liver biopsy before and after treatment were enrolled, and among these patients, 71 with an Ishak stage of ≥3 and qualified results of live biopsy were included in the final analysis. Based on the P-I-R classification, 58% (41/71) were classified as predominantly progressive, 29% (21/71) were classified as indeterminate, and 13% (9/71) were classified as predominantly regressive; there were no significant differences between the three groups in alanine aminotransferase, aspartate aminotransferase, albumin, HBeAg positive rate, HBV DNA, and liver stiffness (P < 0.05). After treatment, the proportion of predominantly progressive, indeterminate, or predominantly regressive patients changed to 11% (8/71), 11% (8/71), and 78% (55/71), respectively. Among the 35 patients who had no change in Ishak stage after treatment, 72% (25/35) were classified as predominantly regressive and had certain reductions in the Laennec score, percentage of collagen area, and liver stiffness. Conclusion: This new P-I-R classification can be used to assess the dynamic changes in liver fibrosis after antiviral therapy in CHB patients.

Abstract
Objective: To explore the role of microRNA-203 in laryngeal cancer and its underlying mechanism and clarify the relationship between microRNA-203 and LASP1.Method: microRNA-203 expression in laryngeal cancer tissues and paracancerous tissues was detected by quantitative real time-polymerase chain reaction(qRT-PCR). The regulatory effects of microRNA-203 on invasion and apoptosis of laryngeal cancer cells were detected by Transwell assay and flow cytometry, respectively. Dual-luciferase reporter gene assay was performed to access the binding condition of microRNA-203 and LASP1. Both mRNA and protein levels of LASP1 in laryngeal cancer cells were detected after transfection with microRNA-203 mimic or microRNA-203 inhibitor by qRT-PCR and Western blot. Rescue experiments were finally performed to detect whether microRNA-203 regulates laryngeal cancer development via targeting LASP1. Result: microRNA-203 was lowly expressed in laryngeal cancer tissues and cell lines.Knockdown of microRNA-203 in Hep-2 cells can promote the invasiveness and inhibit apoptosis of laryngeal cancer cells. Subsequently,LASP1 was predicted to be the target gene of microRNA-203,which was further verified by dual-luciferase reporter gene assay.LASP1 expression was negatively regulated by microRNA-203. Furthermore,rescue experiments showed that microRNA-203 regulates invasion and apoptosis of laryngeal cancer cells via targeting LASP1. Conclusion: Low expression of microRNA-203 could promote the invasion and inhibit apoptosis of laryngeal cancer cells viainhibiting LASP1. microRNA-203 and LASP1 both play a very important role in the development of laryngeal cancer..

Abstract
Objective:To assess the role of LPR in the development of complications, such as hemorrhage, following tonsillectomy in adult patients. We want to provide a guidence for future clinical practice.Method:Totally 70 adult patients who had indication of tonsillectomy were recruited and divided into two groups, the laryngopharyngeal reflux (LPR) group and the control group, which were identified by the results of Reflux Symptom Index (RSI) and Reflux Finding Score (RFS). We observed and compared the postoperative complications of the two groups and analyzed the role of LPR.Result:All the patients complained pain after surgery. The duration of the pain in LPR group was much longer than that of control group. The mean body temperature in both groups was not significantly different (P>0.05). There were six cases of bleeding in the LPR group, while only one case of bleeding occurred in the control group. The difference was statistically significant (P<0.05). There were no cases of infection or pulmonary complications in both groups. All patients were discharged successfully.Conclusion:LPR is closely related to the complications following tonsillectomy.

Abstract
Ternary CdS x Se1-x alloy quantum dots (QDs) and CdS x Se1-x /ZnS core/shell nanocrystals exhibiting composition dependent band gaps have been successfully synthesized. The ZnS shell was doped with 0.1% and 5% of paramagnetic manganese ions so as to be used as a fluorescent/paramagnetic bi-functional probe. Energy-dispersive X-ray spectroscopy (EDS) measurements confirmed the presence of Cd, S, and Se in CdS x Se1-x nanocrystals with the atomic ratios of Cd, S, and Se which are well consistent with our synthetic ratios. Wide angle X-ray diffraction (WAXD) indicated that the crystal structures of the CdS x Se1-x core QDs and CdS x Se1-x /ZnS core/shell QDs were zinc blende phases. Both dynamic light scattering (DLS) and transmission electron microscopy (TEM) revealed that the as-synthesized nanocrystals had a narrow size distribution and high crystallinity. The band gaps of CdS x Se1-x nanocrystals were adjustable by varying the ratio of S:Se in the CdS x Se1-x core and were in the range of 1.96 eV to 2.32 eV. Hence, when composition x was changed from 0 to 1, the fluorescence color of the nanocrystals varied from red to green. After shell coverage, the ternary alloy QDs exhibited a superior photoluminescence (PL) quantum yield up to 57%. In comparison with the alloy core QDs, the PL emission peaks of the CdS x Se1-x /ZnS core/shell QDs displayed a small redshift. Electron paramagnetic resonance (EPR) measurements for manganese-doped CdS x Se1-x /ZnS nanocrystals revealed paramagnetic properties for both low and high Mn2+ doping levels.

Abstract
Vanishing bile duct syndrome (VBDS) manifests as progressive destruction and disappearance of the intrahepatic bile duct caused by various factors and cholestasis. VBDS associated with drug-induced liver injury (D-VBDS) is an important etiology of VBDS, and immune disorder or immune imbalance may be the main pathogenesis. According to its clinical symptoms, serological markers, and course of the disease, D-VBDS is classified into major form and minor form, and its clinical features are based on various pathomorphological findings. Its prognosis is associated various factors including regeneration of bile duct cells, number of bile duct injuries, level and range of bile duct injury, bile duct proliferation, and compensatory shunt of bile duct branches. This disease has various clinical outcomes; most patients have good prognosis after drug withdrawal, and some patients may experience cholestatic cirrhosis, liver failure, and even death. Due to the clinical manifestation and biochemical changes are similar to the primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC), it need to identify by clinical physician.

Abstract
The title complex, {(C(2)H(8)N)[Y(C(2)O(4))(2)(H(2)O)]·3H(2)O}(n), was obtained accidentally under hydro-thermal conditions. The Y(III) atom is chelated by four oxalate ligands and one water mol-ecule resulting in a distorted tricapped trigonal-prismatic geometry. Each oxalate ligand bridges two Y(III) atoms, thus generating a three-dimensional network with cavities in which the ammonium cations and lattice water mol-ecules reside. Various O-H⋯O and N-H⋯O hydrogen-bonding inter-actions stabilize the crystal structure. The title complex is isotypic with the Eu and Dy analogues.

Abstract
A lattice Boltzmann interface capturing method for incompressible flows is proposed in this paper. The interface is naturally captured by minimizing the free energy functional. It is easily implemented and does not require interface reconstruction as required by most of the traditional interface tracking methods such as the volume of fluid method. Moreover, the method does not require the isotropic property of the fourth order lattice tensor as do other lattice Boltzmann methods. Thus the D2Q5 (D2 means two dimensional, Q5 means five velocity model) discrete velocity model is applied in the method. The interface profile along the flat interface and coexistence curve can be given analytically. The proposed method is validated for some test cases, and compared to the volume of fluid and level set methods. Numerical results show that the present method performs very well and can generate very sharp interfaces.
