OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Parkinson's disease (PD) is a chronic neurodegenerative disease. At present, levodopa and other drugs are mainly used for dopamine supplementation therapy. However, the absorption of levodopa in the gastrointestinal tract is unstable and its half-life is short, and long-term use of levodopa will lead to the end-of-dose deterioration, dyskinesia, the "ON-OFF" phenomenon and other symptoms. Therefore, new preparations need to be developed to improve drug efficacy, reduce side effects or improve compliance of patients. Based on the above clinical needs, this review briefly introduced the preparation modification strategies for the treatment of PD through case analysis, in order to provide references for the research and development of related preparations.

Constipation is a prevalent ailment which might significantly impact the quality of people's life and rise some associated deseases risks. In this study, a chronic constipation mouse model was established using loperamide hydrochloride. Mice were gavaged an Angelica sinensis Cistanche Fiber Compound, comprised of Dang Gui [Angelica sinensis (Oliv.) Diels], Rou Cong Rong (Cistanche deserticola Y.C.Ma), wheat fiber, and low-molecular-weight xylan at high dosage (3.6 g·kg^-1, 30 times the recommended human dose) and low dosage (0.6 g·kg^-1, 5 times the recommended human dose) for 14 days. The study assessed the therapeutic efficacy of the compound by observing fecal morphology, measuring water content, and conducting small intestine motility experiments. Furthermore, enzyme-linked immunosorbent assays (ELISA) were conducted to evaluate the serum levels of gastrointestinal hormones including motilin (MTL), gastrin (GAS), the inflammatory factors interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α). Histopathological examination with H&E staining was employed to evaluate colonic tissue damage. Additionally, Western blot and immunohistochemistry experiments were conducted to examine the expression levels of aquaporin-3 (AQP3) and c-Kit in the colon. The results indicated that the Angelica sinensis Cistanche Fiber Compound could improve fecal morphology, increase fecal water content, enhance small intestinal transit rates in mice. Additionally, there was a significant elevation in the serum levels of gastrointestinal hormones and a notable reduction in the levels of inflammatory factors. The improvement in colonic histopathological damage was accompanied by a marked decrease in the expression of the colonic water channel protein AQP3 and a significant increase in c-Kit expression. These results collectively suggested the presence of a dose-response relationship. These findings indicate that the Angelica sinensis Cistanche Fiber Compound effectively alleviates constipation in mice. Its action is associated with the regulation of colonic water channel protein AQP3 and c-Kit expression, along with the modulation of serum inflammatory factors and gastrointestinal hormones. This experiment was approved by the Animal Experiment Ethics Committee of Jinan University.

Objective To investigate the effects of inhibiting KDM2A gene on the proliferation,invasion and migration of liver cancer cells and its possible regulatory mechanism.Methods Forty pairs of HCC tissues and their adjacent normal counterparts were collected from 2014 to 2017 in Tongji Hospital,Tongji Medical College Affiliated to Huazhong University of Science and Technology.Human liver cancer cell lines HepG2,Huh7,HCCLM3,MHCC-97H and normal liver cells LO2 were cultured in vitro.The mRNA and protein expression levels of KDM2A in HCC tissues and cells were detected by qRT-PCR and Western blotting.Huh7 cells were taken and set up as follows:(1)si-NC group(transfected with si-NC)and si-KDM2A group(transfected with si-KDM2A);(2)mimic-NC group(transfected with mimic-NC),miRNA-29a-3p mimic group(transfected with miRNA-29a-3p mimic),inhibitor-NC group(transfected with inhibitor-NC)and miRNA-29a-3p inhibitor group(transfected with miRNA-29a-3p inhibitor).The mRNA and protein expression levels of KDM2A were detected by qRT-PCR and Western blotting.The invasion and migration of cells were detected by Transwell,the proliferation of cells was detected by CCK-8 methods.The online databases TargetScan,miRDIP,miRWalk,Starbase and miRDB were used to predict the binding sites of KDM2A and miR-29a-3p.The KDM2A 3'-UTR(WT)or KDM2A 3'-UTR(MUT)report plasmid was co-transfected with NC-miRNA or miR-29a-3p mimics respectively for 48 h in 293T cells,and the luciferase activity was detected by the luciferase reporter gene detection system.Results Compared with adjacent normal counterparts,the relative mRNA and protein expression levels of KDM2A in HCC tissues increased significantly(P＜0.05).Compared with LO2,the relative mRNA and protein expression levels of KDM2A in HepG2,Huh7,HCCLM3 and MHCC-97H increased significantly(P＜0.05).Compared with si-NC group,the proliferation,invasion and migration of Huh7 cells in si-KDM2A group decreased significantly(P＜0.05 or P＜0.01).The analysis results of TargetScan,miRDIP,miRWalk,Starbase and miRDB showed that there were binding sites between KDM2A and miR-29a-3p.The results of the dual luciferase reporter assay showed that miR-29a-3p mimic significantly reduced KDM2A-MUT luciferase activity(P＜0.01).After overexpression of miRNA-29a-3p,the relative mRNA and protein expression levels of KDM2A were decreased(P＜0.01),the proliferation,invasion and migration abilities were decreased(P＜0.05)in Huh7 cells.After inhibiting the expression of miRNA-29a-3p,the relative mRNA and protein expression levels of KDM2A were increased(P＜0.05),the proliferation,invasion and migration abilities were enhanced(P＜0.05)in Huh7 cells.Conclusion Inhibiting the expression of KDM2A can reduce the proliferation and migration ability of Huh7 cells.miR-29a-3p may be the upstream regulator of KDM2A and participate in the occurrence and development of hepatocellular carcinoma.

Articular cartilage (AC) injuries often lead to cartilage degeneration and may ultimately result in osteoarthritis (OA) due to the limited self-repair ability. To date, numerous intra-articular delivery systems carrying various therapeutic agents have been developed to improve therapeutic localization and retention, optimize controlled drug release profiles and target different pathological processes. Due to the complex and multifactorial characteristics of cartilage injury pathology and heterogeneity of the cartilage structure deposited within a dense matrix, delivery systems loaded with a single therapeutic agent are hindered from reaching multiple targets in a spatiotemporal matched manner and thus fail to mimic the natural processes of biosynthesis, compromising the goal of full cartilage regeneration. Emerging evidence highlights the importance of sequential delivery strategies targeting multiple pathological processes. In this review, we first summarize the current status and progress achieved in single-drug delivery strategies for the treatment of AC diseases. Subsequently, we focus mainly on advances in multiple drug delivery applications, including sequential release formulations targeting various pathological processes, synergistic targeting of the same pathological process, the spatial distribution in multiple tissues, and heterogeneous regeneration. We hope that this review will inspire the rational design of intra-articular drug delivery systems (DDSs) in the future.

AIM: To explore the reasons for screening failure of healthy subjects in clinical trials of orally inhaled drug products (OIDPs). METHODS: Screening data of 1 432 healthy subjects who participated in clinical trials of OIDPs were collected. The main reasons for the screening failure, gender differences in screening failure rate and the correlation between age and screening failure rate were summarized and analyzed. RESULTS: The screening failure rate was 72.4 % and increased with age. The failure rate was slightly higher in females than in males. Besides abnormal vital signs (17.3%), abnormal laboratory test results (16.5%) and withdrawal of consent (7.6%), poor venous condition (13.9%), positive for cigarette test results (12.6%) and failure in inhalation training (7.1%) were also the other three main reasons affecting the screening success rate. Abnormal vital signs and poor venous conditions were the primary screening failure reasons for males and females, respectively. CONCLUSION: The screening success rate could be improved by informing fully and communicating effectively, selecting young subjects with strong understanding abilities, and enhancing the training skills of investigators.

By studying various ancient texts such as herbal classics and medical literature from different eras, it was found that there were discrepancies in the records about Bambusae Concretio Silicea(Tian Zhu Huang). In order to establish an accurate foundation, this research was based on ancient herbal literature and combined with plant morphology and investigative studies to examine its earliest mentions in ancient texts, nomenclature, medicinal properties, indications, and quality assessment standards. In the early records, Bambusae Concretio Silicea was referred to by several different names, such as "Zhu Huang" "Tian Zhu Huang" "Zhu Gao" "Zhu Tang", and "Zhu Huang". The earliest known formal usage of the name "Tian Zhu Huang" was found in the book Ri Hua-zi's Materia Medica(Ri Hua Zi Ben Cao). Throughout various ancient texts, the earliest recorded information about Bambusae Concretio Silicea also appeared in Ri Hua-zi's Materia Medica, not in Materia Medica of Sichuan(Shu Ben Cao) or other ancient texts. Ri Hua-zi's Materia Medica provided relevant descriptions of its origin, medicinal properties, and indications, albeit with some errors due to limited knowledge. However, this has been a valuable starting point for future research on Bambusae Concretio Silicea and holds pioneering significance in forming a mature system. As the research delved deeper, the medicinal properties of Bambusae Concretio Silicea have been consistent since Ri Hua-zi's Materia Medica, and the understanding has gradually improved through years of clinical verification. During the investigation process, the authors found limited records on the quality evaluation of Bambusae Concretio Silicea in ancient texts. Although the information is scarce, it serves as a foundational basis for establishing corresponding quality grading standards for Bambusae Concretio Silicea in the future.

OBJECTIVE: To investigate the effect of Yinlai Decoction (YD) on the microstructure of colon, and activity of D-lactic acid (DLA) and diamine oxidase (DAO) in serum of pneumonia mice model fed with high-calorie and high-protein diet (HCD). METHODS: Sixty male Kunming mice were randomly divided into 6 groups by the random number table method: normal control, pneumonia, HCD, HCD with pneumonia (HCD-P), YD (229.2 mg/mL), and dexamethasone (15.63 mg/mL) groups, with 10 in each group. HCD mice were fed with 52% milk solution by gavage. Pneumonia mice was modeled with lipopolysaccharide inhalation and was fed by gavage with either the corresponding therapeutic drugs or saline water, twice daily, for 3 days. After hematoxylin-eosin staining, the changes in the colon structure were observed under light microscopy and transmission electron microscope, respectively. Enzyme-linked immunosorbent assay was used to detect the protein levels of DLA and DAO in the serum of mice. RESULTS: The colonic mucosal structure and ultrastructure of mice in the normal control group were clear and intact. The colonic mucosal goblet cells in the pneumonia group tended to increase, and the size of the microvilli varied. In the HCD-P group, the mucosal goblet cells showed a marked increase in size with increased secretory activity. Loose mucosal epithelial connections were also observed, as shown by widened intercellular gaps with short sparse microvilli. These pathological changes of intestinal mucosa were significantly reduced in mouse models with YD treatment, while there was no significant improvement after dexamethasone treatment. The serum DLA level was significantly higher in the pneumonia, HCD, and HCD-P groups as compared with the normal control group (P<0.05). Serum DLA was significantly lower in the YD group than HCD-P group (P<0.05). Moreover, serum DLA level significantly increased in the dexamethasone group as compared with the YD group (P<0.01). There was no statistical significance in the serum level of DAO among groups (P>0.05). CONCLUSIONS YD can protect function of intestinal mucosa by improving the tissue morphology of intestinal mucosa and maintaining integrity of cell connections and microvilli structure, thereby reducing permeability of intestinal mucosa to regulate the serum levels of DLA in mice.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
