Objective To investigate the effect of leflunomide(LEF)on the expression of associated autophagy genes in synoviocytes of rheumatoid arthritis(RA)by regulating HIF-1α signal pathway.Methods Three genera-tions of RA synovial cells were divided into blank control group,LEF group and Tripterygium wilfordii polyglyco-sides group.The blank control group was added with the same volume of DMEM culture medium.The drug group was treated with LEF(concentration 0.2 mg/ml)and Tripterygium wilfordii polyglycosides(concentration 0.03 mg/ml),the proliferation and apoptosis of synovial cells were detected by flow cytometry,the expression of IL-1 β,TNF-α,ANGPTL-4 and VEGF was detected by ELISA,the expression of HIF-1α mRNA was detected by qRT-PCR,and the expression of HIF-1 α,Beclin-1 and BNIP3 protein was detected by Western blot.Results Com-pared with Tripterygium wilfordii polyglycosides group,the expression of IL-1 α,TNF-α,ANGPTL-4 and VEGF in synovial supernatant of LEF group decreased;compared with the blank control group,the expression of HIF-1αmRNA in synovial cells of LEF group and Tripterygium wilfordii polyglycosides group decreased,and the effect of LEF group was the most obvious;compared with the blank control group,the protein expressions of HIF-1α,Bec-lin-1 and BNIP3 in synovial cells of LEF group and Tripterygium wilfordii polyglycosides group decreased,and the effect of LEF group was the most obvious.Conclusion LEF can inhibit the expression of inflammatory factors in RA synovial cells,inhibit HIF-1α signaling pathway,inhibit the expression of autophagy-related genes Beclin-1 and BNIP3,and improve the pathological state of synovitis.

Objective To investigate the prevalence of Helicobacter pylori(H.pylori)positivity in the urban areas of Chongqing and its relationship with age,season,and gender.Methods A total of 4,836 patients who underwent 14C-UBT testing at our hospital from April 2023 to March 2024 were selected.The detection rate of H.pylori and the infection status of H.pylori in different age groups,genders,and seasons were analyzed.Logistic regression analysis was performed on factors related to H.pylori infection identified in the univariate analysis.Results The positive detection rate of H.pylori in the 4,836 subjects was 29.3％,with a higher rate in males than in females,showing a statistically significant difference(P＜0.05).The highest positive detection rate of H.pylori was in the summer season,and the peak positivity rate for H.pylori was observed in the 30-39 age group.There was a statistically significant difference in the positive detection rate of H.pylori across seasons and among different age groups(P＜0.05).Multivariate logistic regression analysis indicated that gender,age,and season were all influential factors in the outcome of H.pylori infection(P＜0.05).Conclusion The prevalence of H.pylori infection in the urban areas of Chongqing is relatively low,and gender,age,and season are all influential factors for H.pylori infection.

Objective:To analyze the incidence and clinical phenotype of the concomitant extragenital malformations in the patients with female reproductive tract anomalies.Methods:A retrospective study was conducted using clinical data of hospitalized patients diagnosed with uterine, cervical, or vaginal malformations from January 2003 to December 2022 in Peking Union Medical College Hospital. The malformations were classified according to American Society for Reproductive Medicine müllerian anomalies classification 2021, and in each type, the incidence and specific manifestations of concomitant extragnital malformations were analyzed.Results:A total of 444 patients were included. The overall incidence of concomitant extragenital malformations was 43.5% (193/444), including urinary system, skeletal system, and other system malformations. Renal malformations on the obstructed side were present in all patients with oblique vaginal septum syndrome (100.0%, 78/78). The total incidence of concomitant extragnital malformations was as high as 8/11 in uterus didelphys, 43.5% (10/23) in unicornuate uterus, 33.6% (79/235) in Mayer-Rokitansky-Küster-Hauser syndrome, 18.8% (6/32) in septate uterus and 18.5% (12/65) in cervical agenesis. Urinary system malformations (30.6%, 136/444) and skeletal system malformations (13.5%, 60/444) were the most common concomitant malformations in all types, in which, unilateral renal agenesis and scoliosis were the most common.Conclusions:Urinary and skeletal system malformations are important features of female reproductive tract anomalies. Urologic ultrasonography and spinal roentgenogram are recommended for all patients with female reproductive tract anomalies.

Objective:To analyze the clinical characteristics and medication options of patients with elderly-onset epilepsy and influencing factors for medication efficacy.Methods:A total of 213 patients with elderly-onset epilepsy (age of onset≥65 years) were selected from Epilepsy Outpatient, Department of Neurology, First Medical Center of Chinese PLA General Hospital from February 1999 to March 2023. General data, imaging findings and follow-up results of these patients were collected. Seizure frequencies and types, medication types, and medication efficacy were analyzed retrospectively. According to medication efficacy, these patients were divided into effective anti-seizure medications (ASMs) group and ineffective ASMs group (effective ASMs was defined as having no seizures or seizure reduction>50% at 6 months after medication, and ineffective ASMs as having seizure reduction≤50% or seizure increase. Univariate and multivariate Logistic regression analyses were used to identify the influencing factor for ASMs efficacy.Results:In these 213 patients with elderly-onset epilepsy, 143 (67.1%) were males and 70 (32.9%) were females. Onset age was 70.0 (67.0, 74.5) years, with duration of 12 (4, 32) months. Time from first onset to treatment was 2.0 (1.0, 10.5) months, with that<2 months enjoying the largest proportion ( n=101). MRI/CT in 102 patients indicated potential epileptogenic abnormal structures, such as post-stroke gliosis/encephalomalacia ( n=67) and post-traumatic gliosis/encephalomalacia ( n=13). MRI/CT in 78 patients indicated non-epileptogenic abnormal structures, such as ischemic changes of small and medium vessels ( n=51) and brain atrophy ( n=15). Structural change was the most common cause ( n=160). Sixty-nine patients (32.4%) did not take medicine and 144 (67.6%) took medicine at the visiting; sodium valproate was mostly used ( n=74), followed by levetiracetam ( n=35) and carbamazepine ( n=24). Five patients had sodium valproate combined with levetiracetam, and 4 patients had sodium valproate combined with carbamazepine. Multivariate Logistic regression analysis showed that disease duration and medication combination were independent influencing factors for ASMs efficacy. Conclusion:Structural change is the main cause for elderly-onset epilepsy; medication efficacy is worse in patients with longer disease course and medication combination therapy.

This review aims to sum up how Non-coding RNAs (ncRNAs) regulate the development of periodontitis and provides a new perspective for understanding the pathogenesis of periodontitis. We explored the ncRNA's dual role in the development of periodontitis by summarizing evidence from previous in vivo and in vitro studies as well as clinical samples. In our review, the downregulation of 18 miRNAs, 22 lncRNAs and 10 circRNAs demonstrates protective roles in periodontitis. In contrast, the expression of other 11 miRNAs, 7 lncRNAs and 6 circRNAs are upregulated in periodontitis, which promote the progression of periodontitis. These dysregulated ncRNAs exert their protective or destructive roles by mainly influencing cell proliferation, differentiation and apoptosis via cross-talking with various molecules or signaling pathways. Our findings suggested which and how ncRNAs promote or delay the progression of periodontitis, which may greatly contribute to diagnose and therapy development of periodontitis based on ncRNAs in the future.

Objective : To investigate the role and mechanism of bone formation caused by the ratio of advanced platelet-rich fibrin (A-PRF) and β-tricalcium phosphate (β-TCP) in rabbit femur defect model, which provides a new idea for clinical treatment of bone defect. Methods : Twenty-four New Zealand white rabbits were divided into model group, 1∶1 complex group (A-PRF∶β-TCP=1∶1), 2∶1 complex group (A-PRF∶β- TCP=2∶1) and 4∶1 complex group (A-PRF∶β- TCP=4∶1）, with 6 rabbits in each group. Femoral defect models were constructed in each group. In the composite group, the bone defect was filled with composite material, while in the model group, no material was filled. After 8 weeks, the animals were euthanized and specimens were collected. Bone mineral density (BMD), bone volume fraction (BV/TV), trabecular thickness (Tb.Th), trabecular separation (Tb.SP) and trabecular number (Tb.N) in femoral defect tissue were measured by micro-CT and photographed. Hematoxylin - eosin staining was used to detect the pathological changes of new bone tissue. The morphological changes of the new bone tissue were observed by scanning electron microscopy. Determination of phospho-mitogen activated protein kinase p38 (p-p38MAPK), CCAAT/enhancer binding protein homologous protein (CHOP) and phospho-cysteine aspartic protease-3 (p-Caspase3) in newborn femur by ELISA. The mRNA expressions of osteoprotegerin (OPG), bone morphogenetic protein-2 (BMP-2), receptor activator of nuclear factor kappa-B ligand (RANKL) and p38MAPK were detected by real-time quantitative PCR. The expression of OPG, BMP-2, RANKL, p-p38MAPK and p-Caspase3 protein in the new bone tissue was observed by immunohistochemistry. Results : In the model group, bone formation in the femoral defect area was slow and osteogenic quality was poor. Compared with the model group, the bone formation and neocapillaries of femoral defect area in the complex group was good, BMD, BV.TV, Tb.Th, Tb.N were increased, and Tb.Sp were decreased, the expressions of p-p38MAPK, CHOP and p-Caspase3 were decreased, and the mRNA and protein expressions of OPG and BMP-2 were increased. The mRNA expression of RANKL and p38MAPK was decreased. Apoptosis in new bone tissue of each group showed the lowest apoptosis rate in samples of the 2∶1 complex group (P<0.05); A-PRF: β-TCP=2∶1 ratio has the best osteogenic effect. Conclusion The complex composed of A-PRF and β-TCP can promote the expression of OPG, inhibit the expression of RANKL and phosphorylation of p38MAPK, reduce the apoptosis of new bone tissue cells, and promote osteogenic differentiation.
