Enthesitis in patients with psoriatic arthritis: A nationwide data from the Chinese Registry of Psoriatic Arthritis (CREPAR) / 中华医学杂志(英文版)

BACKGROUND@#The clinical features of enthesitis in patients with psoriatic arthritis (PsA) have been reported in some Western countries, but data in China are very limited. This study aimed to describe the characteristics of enthesitis in Chinese patients with PsA and compared them with those in other cohorts.@*METHODS@#Patients with PsA enrolled in the Chinese Registry of Psoriatic Arthritis (CREPAR) (December 2018 to June 2021) were included. Data including demographics, clinical characteristics, disease activity measures, and treatment were collected at enrollment. Enthesitis was assessed by the Spondyloarthritis Research Consortium of Canada (SPARCC), Maastricht ankylosing spondylitis enthesitis score (MASES), and Leeds enthesitis index (LEI) indices. A multivariable logistic model was used to identify factors related to enthesitis. We also compared our results with those of other cohorts.@*RESULTS@#In total, 1074 PsA patients were included, 308 (28.7%) of whom had enthesitis. The average number of enthesitis was 3.3 ± 2.8 (range: 1.0-18.0). More than half of the patients (165, 53.6%) had one or two tender entheseal sites. Patients with enthesitis had an earlier age of onset for both psoriasis and arthritis, reported a higher proportion of PsA duration over 5 years, and had a higher percentage of axial involvement and greater disease activity. Multivariable logistic regression showed that axial involvement (odds ratio [OR] 2.21, 95% confidence interval [CI], 1.59-3.08; P <0.001), psoriasis area and severity index (PASI) (OR: 1.03, 95% CI: 1.01-1.04; P = 0.002), and disease activity score 28-C reactive protein (DAS28-CRP) (OR: 1.25, 95% CI: 1.01-1.55; P = 0.037) were associated with enthesitis. Compared with the results of other studies, Chinese patients with enthesitis had a younger age, lower body mass index (BMI), a higher rate of positive human leukocyte antigen (HLA)-B27, more frequent dactylitis, and a higher proportion of conventional synthetic disease-modifying antirheumatic drugs' (csDMARDs) use.@*CONCLUSIONS@#Enthesitis is a common condition among Chinese patients with PsA. It is important to evaluate entheses in both peripheral and axial sites.

Association of skin lesion severity with clinical features of psoriatic arthritis / 中华内科杂志

Objective:To investigate the relationship between psoriasis severity and clinical features in psoriatic arthritis (PsA).Methods:Patients were recruited from the Chinese REgistry of Psoriatic ARthritis (CREPAR) between December 2018 and June 2021, and data were collected including the baseline demographic characteristics, various clinical manifestations (including arthritis, nail disease, comorbidities), laboratory tests[including erythrocyte sedimentation rate(ESR), C-reactive protein (CRP)], health assessment questionnaire (HAQ). Body surface area (BSA) and psoriasis area and severity index (PASI) were selected for the tools of assessment of cutaneous psoriasis. Patients were divided to two groups, including the severe psoriasis group (BSA>10%) and the non-severe psoriasis group (BSA≤10%). Disease assessment included ankylosing spondylitis disease activity score (ASDAS), disease activity score 28 (DAS28) and disease activity in psoriatic arthritis (DAPSA).Results:1 074 eligible patients with PsA were recruited, and 106 (9.9%) had severe psoriasis. Compared with non-severe psoriasis group, the severe psoriasis group had more peripheral joint involvement (including patients with ever or current peripheral arthritis, 94.3% vs. 85.6%), more polyarticular joint involvement (including patients with current peripheral arthritis, 74.0% vs. 58.2%), more axial joint involvement (51.4% vs. 39.9%), more nail disease (72.6% vs. 61.4%), more frequency of smoking (20.2% vs. 18.7%), and higher proportion of hypertension (23.4% vs. 14.4%). In addition, the severe psoriasis group had higher level of ESR [33(10, 70) mm/1h vs. 20(9, 38) mm/1h] and CRP [18.6(5.0, 60.8) mg/L vs. 7.0(2.4, 18.1) mg/L], higher values of DAS28-ESR (4.5±1.7 vs. 3.7±1.5), DAS28-CRP (4.2±1.5 vs. 3.4±1.4), ASDAS-ESR (3.5±1.4 vs. 2.6±1.2), and ASDAS-CRP(3.4±1.6 vs. 2.5±1.2), higher scores of HAQ [0.6(0.1, 1.0) vs. 0.3(0.0, 0.8)].Conclusion:Patients with PsA with severe psoriasis bore a heavier disease burden. Therefore, clinicians were supposed to pay more attention to them. In addition to skin lesions, they should also focus on examination of other clinical manifestations, such as joints and nails.

OBJECTIVE To evaluate the cost -effectiveness of tislelizumab in the second -line treatment of advanced or metastatic esophageal squamous cell carcinoma （ESCC）in China .METHODS A three -state Markov model was constructed to assess the cost -effectiveness of tislelizumab versus chemotherapy in the second -line treatment of advanced or metastatic ESCC and programmed death receptor 1（PD-L1）positive patients . The cycle length of the model was 1 month，and the time horizon of the model was set as 10 years. The discount rate of cost and utility was 5%. One-way sensitivity analysis ，probability sensitivity analysis and scenario analysis were used to verify the robustness of the base -case analysis results . RESULTS The results of the base-case analysis showed that compared with chemotherapy ，the incremental cost -effectiveness ratio （ICER）of tislelizumab in the second-line treatment of advanced or metastatic ESCC and PD -L1-positive patients were 26 864.01 yuan/QALY and 37 510.07 yuan/QALY，respectively，which was much lower than 1 time per capita gross domestic product （GDP）in 2021（80 976 yuan）. Results of scenario analysis showed that the ICER was less than 1 times per capita GDP ，regardless of the chemotherapy regimens（paclitaxel，docetaxel or irinotecan ）used. With the extension of the simulation time limit ，the ICER of tirelizumab regimen gradually decreased ，and the reduction rate gradually E-mail：lishunping@sdu.edu.cn decreased，but they were all less than 1 time China ’s per capita GDP in 2021. The results of the one -way sensitivity analysis showed that the 3 parameters with the most significant impact on the ICER were progression -free survival of tislelizumab group ，price of tislelizumab ，and the proportion of patients receiving follow-up treatment in the tislelizumab group . The results of the probability sensitivity analysis showed that the probability of tislelizumab with cost -effectiveness in the treatment of advanced or metastatic ESCC patients and PD -L1-positive patients were 99.09% and 99.94%，respectively，when using 3 times per capita GDP as the willingness -to-pay threshold . CONCLUSIONS Tislelizumab has economic advantages over chemotherapy alone in the second -line treatment of advanced or metastatic ESCC patients.

Current Situation and Prospect of Pharmacoeconomic Evaluation of Hemophilia in China / 罕见病研究

In 2018, hemophilia, one of the first ones, entered into the catalogue of Rare Disease in China. However, drug accessibility and affordability have been the challenges for hemophilia patients. Therefore, a comprehensive evaluation of the cost and efficacy of hemophilia drugs is essential to push forward the appropriate application of hemophilia drugs. In the article, we have teased out the existing process of the review and approval of hemophilia drugs; have examined the procedures for the drug entry into the medical insurance policy; have systematically searched the pharmacoeconomic evaluation studies of hemophilia in published literature in both China and overseas; and have comprehensively analyzed the quality, the content of evaluation, and challenges of pharmacoeconomic studies of hemophilia in China. At last, we discuss the prospect for the future based on the following three aspects: developing a special model of hemophilia, obtaining the health utility from various sources, and establishing the threshold of willingness to pay for rare diseases, hoping to provide reference and examples to the research into pharmacoeconomic evaluation of hemophilia in China.

Clinical Progress in Negative-Pressure Endometrial Sampler for Endometrial Cancer Screening / 中国医科大学学报

Endometrial cancer is a common malignancy of the female reproductive system. Despite improvement in living standards, the incidence of endometrial cancer is increasing due to the lack of effective screening. Early detection of endometrial cancer and precancerous lesions can significantly improve prognosis and survival. At present, China lacks a method for screening endometrial lesions comparable to that for cervical cancer screening. A recently introduced endometrial sampler has the advantages of simple operation, low cost, and minimal trauma, and is gradually being accepted for clinical screening of endometrial cancer and precancerous lesions in other countries.This study aims to explore current screening methods for endometrial cancer and precancerous lesions and the clinical application of an endometrial sampler for screening.

Role of tumor-derived exosomes in tumor metastasis / 国际肿瘤学杂志

Tumor-derived exosomes (TEXs) are small membrane vesicles secreted by tumor cells.They contain various proteins and RNA which make they serve as functional mediators in cell interaction.TEXs can alter the components of extracellular matrix and induces epithelial-mesenchymal transition of tumor cells,which enhance the invasiveness of tumor cells.TEXs regulate immunity through multiple pathways,allowing circulating tumor cells to escape immune surveillance.TEXs promote pre-metastatic microenvironment in target organ before metastasis and induce angiogenesis after circulating tumor cells colonization.Understanding the role and mechanism of TEXs in this process can effectively block relevant signaling pathways which may provide new targeted therapies for clinic.

Effects of concentrated growth factors on the angiogenic properties of dental pulp cells and endothelial cells: an in vitro study

Abstract The aim was to investigate the angiogenic effects of concentrated growth factors on human dental pulp cells and human umbilical vein endothelial cells. Cells were treated with concentrated growth factor extracts. The CCK-8 assay and cell cycle assay were conducted to evaluate cell growth. Cell migration was evaluated by the Transwell migration assay. Angiogenesis-associated mRNA and protein expression levels were determined using quantitative real-time PCR and Western blotting, respectively. A tube formation assay was conducted to evaluate the angiogenic capacity in vitro. The data showed that compared with the control, concentrated growth factor extracts significantly promoted dental pulp cell proliferation and differentiation and endothelial cell proliferation and migration in a dose-dependent manner (p < 0.05). Concentrated growth factor extracts also promoted the tube-like structure formation of endothelial cells in vitro. The RT-PCR and Western blot results showed that concentrated growth factor extracts upregulated the expression of angiogenesis-related genes - chemokine receptor-4, platelet-derived growth factor, and vascular endothelial growth factor - in dental pulp cells. In conclusion, concentrated growth factors showed proangiogenic effects on dental pulp cells and endothelial cells and have good application potential for dental pulp revascularization.
