Objectives To describe the Epstein Barr virus (EBV) infection of children in Hefei, analyze its epidemiological characteristics, and explore the factors affecting EBV infection. Methods The children as the outpatient in the department of our hospital were recruited as the research subjects from June 2018 to June 2021. Epidemiological data of the research subjects were collected from medical records and the laboratory tests were performed to detect the related serological indicators of EBV. The distribution characteristics of different serological antibodies of EBV were described. According to the types of serological antibodies, all research subjects were divided into three states: primary infection, previous infection and non-infection. Logistics regression was used to analyze the factors affecting the infection status. Results There were 480 children in this study. The mean age and body mass index of all research subjects were 8.7±1.5 years and 20.78±3.2kg/m2, respectively. There were 276 boys(57.50%) and 204 girls(42.50%). 67 children(12.92%) were positive for VCA-IgM antibody. 326 children(67.92%) were positive for VCA-IgG antibody. 290 children(60.42%) were positive for NA-IgG antibody and 25 children(5.21%) were positive for EA-IgG antibody. There was no significant distribution difference of serological antibodies in gender, season of onset, disease duration, fever, angina and enlargement of lymph nodes. However, there were significant distribution differences of serological antibodies among different body mass index(χ²=50.207, P<0.001) and age(χ²=48.295, P<0.001). According to the types of serological antibodies, all research subjects were divided into three states. There were 78(16.25%) children with primary infection, 335(69.79%) with previous infection and 67(13.96%) with non-infection. Only age was the main factor affecting infection status by Logistic regression analysis(P_{primary infection vs. non-infection}<0.001, OR_{primary infection vs. non-infection}=0.580; P_{previous infection vs. non-infection}=0.038, OR_{previous infection vs. non-infection}=2.347). Conclusion The previous infection by EBV is the mainly infection type in children aged 6 to 12 year. The positive VCA-IgG antibody accounts for the most in previous infection. Age is the important influencing factor on EB infection. The younger the age, the higher the probability of primary infection. Besides, the positive VCA-IgM antibody is the main pattern of primary infection in children.

Objective To investigate the effect of ERH gene knockdown on the proliferation and apoptosis of human bladder cancer T24 cells. Methods T24 cells infected by lentivirus with interference on ERH gene sequence were cloned to establish stable T24 cells clone in ERH gene suppression. The expression of ERH mRNA gene in bladder cancer was detected by using quantitative real time polymerase chain reaction (qPCR). The effects of ERH knockout on the cell proliferation and apoptosis were examined by using methylthiazolyl tetrazolium (MTT) assay, colony formation assay and flow cytometry. The effect of ERH knockout on the tumorigenic effect of T24 cells in vivo was verified by subcutaneous tumor formation in nude mice. Results After lentiviral transfection, qPCR results showed that the knockdown effect of ERH mRNA in ERH normal group (untreated T24 cells) was better than that in ERH gene knockdown group, and the difference was statistically significant [(1.006±0.126) vs. (0.079±0.007); t=12.72, P=0.0002]. After knocking out ERH gene, MTT assay showed that the proliferation ability of T24 cells in ERH gene knockdown group was weakened compared with ERH normal group, and the difference was statistically significant [A490 value: (0.13±0.00) vs. (0.66±0.01);t=104.61, P<0.0001]. Colony formation assay indicated that the ability of clone in ERH normal group was weakened compared with ERH gene knockdown group [(10.5 ±1.2) vs. (196.4 ±4.0); t= 73.63, P< 0.0001]. Flow cytometry showed that the cell apoptosis rate in ERH gene knockdown group was higher than that in ERH normal group [(11.0 ±0.5) ％ vs. (4.2 ±0.5) ％; t= 16.06, P<0.0001]. Imaging results of subcutaneous tumor formation in nude mice showed that the total fluorescence intensity of the tumor area in ERH gene knockdown group was (4.67 ±0.59) × 1010 μW/cm2, and the corresponding part in ERH normal group was (9.54±4.20) × 1010μW/cm2 (t=3.64, P=0.0051);tumor weight in ERH gene knockdown group was (0.80±0.62) g, and in ERH normal group was (1.79±0.71) g (t=3.33, P=0.0037). Conclusion ERH gene knockout can inhibit the proliferation of human bladder cancer T24 cells, and promote the cell apoptosis.

Objective:In general, patients with seropositive rheumatoid arthritis (RA) are considered to show an aggressive disease course. However, the relationship between the two subgroups in disease severity is controversial. Our study is aimed to compare the clinical characteristics and prognosis of double-seropositive and seronegative RA in China through a real-world large scale study.Methods:RA patients who met the 1987 American College of Rheumatology (ACR) classification criteria or the 2010 ACR/European Anti-Rheumatism Alliance RA classification criteria, and who attended the 10 hospitals across the country from September 2015 to January 2020, were enrolled. According to the serological status, patients were divided into 4 subgroups [rheumatoid factor (RF)(-) anti-cyclic citrullinated peptide (CCP) antibody (-), RF(+), RF(+) anti-CCP antibody(+), anti-CCP antibody(+)] and compared the disease characteristics and treatment response. One-way analysis of variance was used for measurement data that conformed to normal distribution, Kruskal-Wallis H test was used for measurement data that did not conform to normal distribution; paired t test was used for comparison before and after treatment within the group if the data was normally distributed else paired rank sum test was used; χ2 test was used for count data. Results:① A total of 2 461 patients were included, including 1 813 RF(+) anti-CCP antibody(+) patients (73.67%), 129 RF(+) patients (5.24%), 245 RF(-) anti-CCP antibody(-) patients (9.96%), 74 anti-CCP antibody(+) patients (11.13%). ② Regardless of the CCP status, RF(+) patients had an early age of onset [RF(-) anti-CCP antibody(-) (51±14) years old, anti-CCP antibody(+) (50±15) years old, RF(+) anti-CCP antibody(+) (48±14) years old, RF(+)(48±13) years old, F=3.003, P=0.029], longer disease duration [RF(-) anti-CCP antibody(-) 50 (20, 126) months, anti-CCP antibody(+) 60(24, 150) months, RF(+) anti-CCP antibody(+) 89(35, 179) months, RF(+) 83(25, 160) months, H=22.001, P<0.01], more joint swelling counts (SJC) [RF(-) anti-CCP antibody(-) 2(0, 6), Anti-CCP antibody(+) 2(0, 5), RF(+) anti-CCP antibody(+) 2(0, 7), RF(+) 2(0, 6), H=8.939, P=0.03] and tender joint counts (TJC) [RF(-) anti-CCP antibody(-) 3(0, 8), anti-CCP antibody(+) 2(0, 6), RF(+) anti-CCP antibody(+) 3(1, 9), RF(+) 2(0, 8), H=11.341, P=0.01] and the morning stiff time was longer [RF(-) anti-CCP antibody(-) 30(0, 60) min, anti-CCP antibody(+) 20(0, 60) min, RF(+) anti-CCP antibody(+) 30(10, 60) min, RF(+) 30(10, 60) min, H=13.32, P<0.01]; ESR [RF(-) anti-CCP antibody(-) 17(9, 38) mm/1 h, anti-CCP antibody(+) 20(10, 35) mm/1 h, RF(+) anti-CCP antibody(+) 26(14, 45) mm/1 h, RF(+) 28(14, 50) mm/1 h, H=37.084, P<0.01] and CRP [RF(-) anti-CCP antibody(-) 2.3 (0.8, 15.9) mm/L, Anti-CCP antibody(+) 2.7(0.7, 12.1) mm/L, RF(+) anti-CCP antibody(+) 5.2(1.3, 17.2) mm/L, RF (+) 5.2(0.9, 16.2) mm/L, H=22.141, P<0.01] of the RF(+)patients were significantly higher than RF(-) patients, and RF(+) patients had higher disease severity(DAS28-ESR) [RF(-) anti-CCP antibody(-) (4.0±1.8), anti-CCP antibody(+) (3.8±1.6), RF(+) anti-CCP antibody(+) (4.3±1.8), RF(+) (4.1±1.7), F=7.269, P<0.01]. ③ The RF(+) anti-CCP antibody(+) patients were divided into 4 subgroups, and it was found that RF-H anti-CCP antibody-L patients had higher disease severity [RF-H anti-CCP antibody-H 4.3(2.9, 5.6), RF-L anti-CCP antibody-L 4.5(3.0, 5.7), RF-H anti-CCP antibody-L 4.9(3.1, 6.2), RF-L anti-CCP antibody-H 2.8(1.8, 3.9), H=20.374, P<0.01]. ④ After 3-month follow up, the clinical characteristics of the four groups were improved, but there was no significant difference in the improvement of the four groups, indicating that the RF and anti-CCP antibody status did not affect the remission within 3 months. Conclusion:Among RA patients, the disease activity of RA patients is closely related to RF and the RF(+) patients have more severe disease than RF(-) patients. Patients with higher RF titer also have more severe disease than that of patients with low RF titer. After 3 months of medication treatment, the antibody status does not affect the disease remission rate.

Objective:To retrospectively analyze the serological, virological, biochemical, liver histological status and clinical outcomes in HBeAg-negative chronic hepatitis B (CHB) patients with low HBV viral load, and to explore the necessity of antiviral therapy for these patients.Methods:A total of 99 HBeAg-negative CHB patients with HBV DNA level < 4 lg copies/ml who performed liver biopsy at the baseline were enrolled from the follow-up cohort. Among them, 23 cases received the second liver biopsy during follow-up. The relationships among the degree of inflammation and fibrosis of liver tissues, the status of HBsAg and HBcAg, age, gender, family history, HBV DNA load, serological markers and other indicators were analyzed. The pathological differences between two liver biopsy examinations were compared. The effect of nucleos(t)ide analogues (NAs) treatment on patient’s clinical outcomes were analyzed. For multivariate analysis, a binary logistic regression model was performed. Log-rank test was used to compare the cumulative incidence of hepatocellular carcinoma (HCC) in NAs-treated and non-NA streated patients.Results:Baseline liver histology status showed that 58.6% (58/99) patients had obvious liver tissue damage in their baseline liver tissue pathology (G≥2 and /or S≥2). Univariate logistic regression analysis showed that a liver cirrhosis (LC) family history, a HBsAg-positive family history, baseline alanine aminotransferase and aspartate aminotransferase levels were positively correlated factors for liver tissue damage. Multivariate logistic regression analysis showed that a LC family history was the main risk factor for liver tissue damage. Twenty-three cases had received a second liver biopsy after an interval of 4.5 years. In 10 untreated cases, the second liver biopsy results showed the rate of obvious liver tissue damage (G≥2 and/ or S≥2) increased from 50.0% to 90.0%. In the other 13 cases who received NAs treatment, the second liver biopsy showed improvement in liver histology, and the rate of obvious liver tissue damage decreased from 61.5% to 46.2%. The 5-year HCC cumulative incidence in non-NAs-treated patients was significantly higher than that of in NAs-treated patients (17.7% vs. 3.8%, P = 0.046). Conclusion:For most HBeAg-negative CHB patients with low viral load, liver tissue pathology result suggests that it meets the indications for antiviral therapy, especially in patients with a LC familial history. Without antiviral therapy, liver tissue damage for these patients will progressively worse with the high incidence of HCC. Therefore, it is suggested that antiviral therapy should be started as soon as possible for the HBeAg-negative CHB patients with low viral load regardless of the alanine aminotransferase level, especially in patients over 30 years-old with a LC or HCC family history.
