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 investigate the impact of previous cystectomy for ovary benign cyst on ovarian reserve and pregnancy outcome in in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) cycles. Methods Totally 622 infertility patients were retrospectively investigated who underwent first IVF/ICSI-ET cycle in Reproductive Hospital Affiliated to Shandong University from January 2013 to June 2014. There were 153 cases who had been removed ovarian cyst by cystectomy surgeries recruited as study group, in which 44 cases of ovarian endometriosis cyst, 35 cases of benign ovarian teratomas, 67 cases of simple ovarian cyst and 7 cases of ovarian mucinous cystadenoma. In contrast, 469 infertility patients with tubal-factor infertility or male factor were included as control group. The age-matched women in the control group had no ovarian surgery previously. The indicators of ovarian reserve and pregnancy outcome were analyzed between two groups. The influence of different types of ovarian cysts on ovarian reserve and pregnancy outcome in IVF/ICSI-ET cycles were also studied, ovarian endometriosis cyst was studied as Group A, and Group B consisted of benign ovarian teratomas, simple ovarian cyst and mucinous cystadenoma. Results (1) The significantly lower serum antimullerian hormone (AMH) level (median: 1.92 versus 2.90 mg/L), antral follicle count (AFC; median: 12.0 versus 13.0), retrieved oocytes (12 ± 5 versus 13 ± 6) and the number of embryo cryopreserved (median:1.0 versus 3.0) were found in study group compared with control group (all P0.05). A better clinical pregnancy rate was achieved in control group (61.6%, 241/391) than that in study group (61.4%, 81/132), but no significant difference was existed (P=0.96). (2) Compared to Group B, Group A had fewer AFC, lower serum AMH level, retrieved oocytes and the number of embryo cryopreserved (11±4 versus 13±5;1.65 versus 2.15 mg/L;9±4 versus 13±5;0 versus 2.0;all P0.05). Conclusions Ovarian reserve declines after the cystectomy for ovarian benign cysts and the cystectomy has a negative impact on IVF/ICSI-ET cycle, resulting in a decrease of the number of retrieved oocytes and the number of embryo cryopreserved, but do not influence clinical pregnancy outcome. Ovarian reserve is impaired more seriously by cystectomy for ovarian endometriosis cyst than other ovarian benign cyst.

Objective To confirm the clinical diagnosis of complete androgen insensitivity syndrome (CAIS) by molecular genetic testing in a large family. Methods PCR was performed to amplify the coding region of androgen gene, followed by direct sequencing in the patients with CAIS and relatives in this family. Results A missense mutation Arg773His was identified in the patients (homozygous) and carriers(heterozygous). Conclusions Mutation Arg773His in the AR gene leads to CAIS in this family. Molecular genetic testing of CAIS facilitates not only prenatal genetic diagnosis but also preimplantation genetic diagnosis and offers genetic counseling for future pregnancies to abandon the transmission of the mutated X chromosome to the coming generation.
