ObjectiveTo analyze the clinical treatment plan and traditional Chinese medicine (TCM) medication rule of children with primary nephrotic syndrome (PNS) in the First Affiliated Hospital of Henan University of Chinese Medicine. MethodsThe gender and age of children firstly diagnosed with nephrotic syndrome in the pediatric nephrology department of the First Affiliated Hospital of Henan University of Chinese Medicine from November 2019 to December 2022 were collected, and the use of immunosuppressive agents and related frequencies were counted. According to the inclusion and exclusion criteria, an independent TCM prescription database for children with nephrotic syndrome was established. Excel was used to analyze the relevant information of the literature. The frequency counting, association rule analysis, and cluster analysis were carried out on TCM in the prescription, and the high-frequent drugs were analyzed. Results(1) General information: A total of 711 children were included, consisting of 522 males (73.42%) and 189 females (26.58%). The ratio of male to female was about 2.76∶1. The disease mainly occurred in infants and preschool age, and the average age of onset was (4.74 ± 3.48) years old. (2) Clinical treatment plan and use of immunosuppressive agents: Of the 711 children with PNS, 237 were treated with hormone alone (32.33%), and 474 (66.67%) received immunosuppressive agents combined with hormones. In the initial treatment, hormone combined with Tacrolimus (TAC) was the preferred treatment (32.91%). For children with refractory PNS who exhibited poor clinical efficacy, Rituximab (RTX) was mostly used for treatment, with a ratio of up to 23.63%. (3) TCM syndrome and medication rule: In PNS syndrome differentiation, Qi and Yin deficiency was identified as the main syndrome. This involved a total of 477 cases, accounting for 67.09%. Yang deficiency of spleen and kidney was observed in 118 cases, accounting for 16.60%. A total of 711 children were included, of which 706 children were treated with TCM. This involved a total of 706 prescriptions, 226 TCM, and 9 793 frequencies. There were 30 herbs used more than 95 times. The top five TCM were Radix et Rhizoma Glycyrrhizae (81.16%), Radix Astragali (71.81%), Poria (68.84%), Rhizoma Atractylodis Macrocephalae (63.60%), and Fructus Corni (57.37%). The drug association rules and network diagram showed that the combination of ''Radix Astragali-Rhizoma Atractylodis Macrocephalae-Poria'' was the closest, and five types of combinations were obtained by cluster analysis. ConclusionIn the diagnosis and treatment of PNS in children, TAC combined with hormones shows good clinical efficacy and high safety. For children with refractory PNS, RTX combined with hormones can be used. TCM medication for PNS should follow the basic principles of strengthening the body and vital Qi and make good use of drugs such as Radix Astragali, Poria, Rhizoma Atractylodis Macrocephalae, and cornus to regulate the Yin and Yang balance and achieve better clinical efficacy.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.
