Objective: To understand the distribution characteristics of high-risk populations for chronic obstructive pulmonary disease (COPD) among residents aged ≥40 years in Inner Mongolia Autonomous Region, so as to provide a basis for comprehensive prevention and control of COPD. Methods: A multi-stage stratified cluster random sampling method combined with probability proportional to size sampling was used to select residents aged ≥40 years from May to December 2019 in 4 monitoring sites in Inner Mongolia Autonomous Region for a questionnaire survey. Information on demographics, current or past smoking, severe respiratory infections in childhood, exposure to occupational harmful factors, exposure to indoor polluting fuels, chronic respiratory symptoms, personal history of chronic respiratory diseases, and family history of chronic respiratory diseases was collected. The distribution characteristics of high risk populations of COPD and high-risk factors were analyzed. Results: A total of 2 302 people were surveyed, including 1 234 males (53.61%) and 1 068 females (46.39%). The mean age was (57.87±8.67) years. A total of 2 114 people (91.83%) were exposed to at least one high-risk factor. The exposure rate of risk factors was 87.88%. There were significant differences in the exposure rates of risk factors among residents of different genders, ages, residence, and occupations (all P<0.05). The exposure rate was higher in males than in females, higher in the 50-60 years than in the 60-<70 years, higher in rural areas than in urban areas, and higher among those engaged in agriculture, forestry, animal husbandry, fishery, and water conservancy than among national enterprise clerks, professional and technical personnel, and retirees (all P<0.05). The prevalence of chronic respiratory symptoms was 14.73%. There were significant differences in the prevalence of chronic respiratory symptoms among residents of different residence and occupations (all P<0.05). The prevalence was higher in rural areas than in urban areas, and higher among those engaged in agriculture, forestry, animal husbandry, fishery, and water conservancy than among retirees (all P<0.05). The exposure rate of personal history of chronic respiratory diseases was 10.90%. There were significant differences in the exposure rate of personal history of chronic respiratory diseases among residents of different educational levels, residence, and occupations (all P<0.05). The exposure rate was higher among those with primary education or below and junior high school education than among those with high school education or above, higher in rural areas than in urban areas, and higher among those engaged in agriculture, forestry, animal husbandry, fishery, and water conservancy than among retirees (all P<0.05). The exposure rate of family history of chronic respiratory diseases was 22.85%. The exposure rate was higher in rural areas than in urban areas (P<0.05). Among residents exposed to risk factors, the exposure rate of current or past smoking was 38.84%, the exposure rate of severe respiratory infections in childhood was 2.13%, the exposure rate of occupational harmful factors was 44.27%, and the exposure rate of indoor polluting fuels was 60.12%. The exposure rates of current or past smoking and occupational harmful factors were higher in males and rural residents (all P<0.05). Conclusions The proportion of high-risk populations for COPD among residents aged ≥40 years in Inner Mongolia Autonomous Region is relatively high. It is recommended to strengthen health education for male residents, rural residents, and those engaged in agriculture, forestry, animal husbandry, fishery, and water conservancy, and to adopt comprehensive prevention and control strategies to reduce the exposure level of risk factors among residents.

Objective To explore the feasibility and safety of fastest recovery after surgery(FRAS)in laparoscopic surgery of gastrointestinal tumors.Methods The clinical data of patients undergoing laparoscopic surgery for gastrointestinal tumors under FRAS and enhanced recovery after surgery(ERAS)from Jan.2023 to May 2024 were collected,and perioperative safety and medical cost were analyzed.Results A total of 87 patients were enrolled,including 43 in the FRAS group and 44 in the ERAS group.Compared with the ERAS group,the FRAS group had significantly shorter surgical time(3.0[2.5,3.5]h vs 3.0[2.5,4.0]h),first postoperative movement time([2.85±4.29]h vs[20.18±6.13]h),first postoperative oral feeding time(2.0[2.0,3.0]h vs 24.0[15.0,48.0]h),postoperative hospital stay(24.0[20.0,40.0]h vs 192.0[150.0,216.0]h),lower hospitalization costs(50 515.61[46 650.44,56 827.12]yuan vs 65 555.09[58 683.21,86 239.02]yuan),and lower medication costs(2 671.09[2 063.31,3 127.09]yuan vs 7 326.90[5 104.66,10 674.26]yuan)(all P＜0.05).Conclusion It is safe and feasible to use FRAS during the perioperative period of laparoscopic radical gastrectomy for gastrointestinal tumors,and FRAS can also reduce the costs of hospitalization and medications.

Standardized clinical trial reporting is crucial for ensuring the scientific validity,reproducibility,and clinical translational value of reported results.The Consolidated Standards of Reporting Trials(CONSORT)statement,an internationally recognized guideline for randomized controlled trials(RCTs),has become an important reference standard for writing research papers in medicine since the 2010 version of CONSORT was published.With advancements in scientific research methodologies and the emergence of new forms of clinical trials,the CONSORT working group released an updated version in April 2025,published in journals such as The BMJ.Herein,we provide a systematic interpretation of the core revisions of CONSORT 2025,as well as a comparison with CONSORT 2010 to highlight the key differences.By providing practical,example-based recommendations,we aim to help domestic researchers apply the new guidelines efficiently,thereby improving the quality of clinical trial reports authored by domestic researchers.

A high-quality clinical trial protocol is the cornerstone for ensuring the scientific integrity and ethical compliance of a study.The Standard Protocol Items:Recommendations for Interventional Trials(SPIRIT)has become the international benchmark for developing clinical trial protocols since its release in 2013.To adapt to the developing trends of open science and patient-centered principles,the SPIRIT group completed a comprehensive update in 2025.While retaining its core structure,this updated guideline introduces a new open science module and incorporates several new elements,including patient and public involvement,trial monitoring,and data sharing,alongside substantial revisions of five pre-existing items.In this article,we critically examine the core revisions in SPIRIT 2025 and,through analysis of representative case studies,illustrate the practical application of the new reporting guideline in drafting trial protocols.Our goal is to to provide Chinese researchers with a valuable reference for understanding and implementing this new reporting guideline,thereby enhancing the quality and rigor of clinical trial protocols developed in the country.

OBJECTIVES: To analyze the differentially expressed exosomal miRNAs in patients with chronic heart failure (CHF) complicated by hyperuricemia (HUA) and explore their potential as novel diagnostic molecular markers and their target genes. METHODS: This study was conducted among 30 CHF patients with HUA (observation group) and 30 healthy volunteers (control group) enrolled between September, 2020 and September, 2023. Peripheral blood samples were collected from 6 CHF patients with HUA for analyzing exosomal miRNAs by high-throughput sequencing, and the results were validated in the remaining 24 patients using qRT-PCR. GO and KEGG enrichment analyses were performed to predict the the target genes of the identified differential miRNAs. We also validated the differentially expressed miRNAs by animal experiment. RESULTS: A total of 42 differentially expressed exosomal miRNAs were detected in observation group by high-throughput sequencing; among them, miR-27a-5p was significantly upregulated (P=0.000179), and miR-139-3p was significantly downregulated (P=0.000058). In the 24 patients with both CHF and PUA, qRT-PCR validated significant upregulation of miR-27a-5p (P=0.004) and downregulation of miR-139-3p (P=0.005) in serum exosomes. When combined, miR-27a-5p and miR-139-3p had a maximum area under the curve (AUC) of 0.899 (95% CI: 0812-0.987) for predicting CHF complicated by HUA. GO and KEGG enrichment analyses suggested that the differential expressions of miR-27a-5p and miR-139-3p was associated with the activation of the AMPK-mTOR signaling pathway to activate the autophagic response. We obtained the same conclusion from animal experiment. CONCLUSIONS Upregulated exosomal miR-27a-5p combined with downregulated exosomal miR-139-3p expression can serve as a novel molecular marker for diagnosis of CHF complicated by HUA, and their differential expression may promote autophagy in cardiomyocytes by activating the AMPK-mTOR signaling pathway.

Objective:To analyze three reconstruction techniques and mid-term clinical outcomes of hip revision for acetabular bone defect after total hip arthroplasty (THA).Methods:This is a retrospective case series study. Included in the study were 109 patients (109 hips) with acetabular bone defect after THA reconstructions in hip revisions from January 2015 to December 2021 in the Senior Department of Orthopaedics, the Forth Medical Center of Chinese People′s Liberation Army General Hospital and the Department of Orthopaedics, the First Medical Center of Chinese People′s Liberation Army General Hospital. According to the preoperative simulated surgeries and different bone defect reconstruction techniques, patients were divided into a normal cup group, an augment group or a triflange group,respectively. There were 54 patients (54 hips) in the normal cup group, reconstructed with the uncemented porous metal cup (including Jumbo cup), with 23 males and 31 females, aged (59.6±9.9) years (range:32 to 76 years); 44 patients (44 hips) in the augment group, reconstructed with the individualized three-dimensional (3D) printed porous metal augment and uncemented porous metal cup, with 18 males and 26 females, aged (52.8±13.6) years(range:17 to 76 years); 11 patients (11 hips) in the triflange group, reconstructed by the individualized 3D printed porous metal triflange cup, with 5 males and 6 females, aged (59.4±11.2) years (range: 43 to 78 years). Radiographic results, including rotation center height, rotation center offset, and leg length discrepancy (LLD) and clinical results, including Harris hip score (HHS) and visual analogue scale(VAS) were evaluated outpatient at 3, 6, 12 months after the operation and annually thereafter. The last follow-up was completed in March 2024, and all parameters at the last follow-up and before the operation were compared. Paired sample t test and repeated measurement ANOVA were used for the radiographic and clinical parameters before and after the operation. Results:All hip revisions for patients with acetabular bone defect after THA were completed and followed for more than two years. The follow-up time of the normal cup group was (6.5±1.7) years (range: 2.8 to 9.3 years), and that of the augment group was (6.0±1.3) years (range: 3.5 to 9.0 years). The follow-up time of the triflange group was (2.8±0.6) years (range: 2.0 to 3.8 years). At the last follow-up, the rotation center height, rotation center offset and LLD of 54 hips in the normal cup group were (24.2±5.6) mm, (29.1±5.5) mm and (4.6±3.3) mm, respectively, and the rotation center height and LLD were significantly lower than those of the preoperative hips ( t=9.671, P<0.01; t=6.073, P<0.01). In the augment group, the rotational center height, the rotation center offset and the LLD of 44 hips were (22.4±9.0) mm, (25.4±5.5) mm and (6.0±4.0) mm, respectively, which were significantly lower than those of the preoperative hips ( t=9.071, P<0.01; t=11.345, P<0.01; t=4.927, P<0.01). In the triflange group, the rotational center height, the rotation center offset and LLD of 11 hips were (22.7±6.0) mm,(30.9±8.0) mm and (5.3±2.2) mm, respectively, and the rotation center height and LLD were significantly lower than those of the preoperative hips ( t=2.716, P=0.022; t=6.226, P<0.01). At the last follow-up, fractures occurred in 3 patients and dislocation occurred in 1 patient in the normal cup group, and fracture reduction and closed reduction were administered under anesthesia, respectively. In the augment group, dislocation occurred in 1 patient and open reduction under anesthesia was performed. The HHS and VAS of the three groups improved significantly after surgery and the differences were statistically significant (all P<0.01). There was no complication in the triflange group. The X-ray at the last follow-up showed that all prostheses and augments were in stable positions and no loosening or migration was observed. Conclusions:For patients with acetabular bone defect after THA undergoing hip revisions, preoperative surgical simulation and rehearsal could help surgeons choose convenient and efficient reconstruction techniques. The targeted selection of Jumbo cup, individualized 3D printed metal augment, and customized triflange cup could achieve satisfactory clinical outcomes.

Acute necrotizing encephalopathy (ANE) is a rare but deadly complication with an unclear pathogenesis. We aimed to elucidate the immune characteristics of H1N1 influenza virusassociated ANE (IANE) and provide a potential therapeutic approach for IANE. Seven pediatric cases from a concentrated outbreak of H1N1 influenza were included in this study. The patients’ CD4+T cells from peripheral blood decreased sharply in number but highly expressed Eomesodermin (Eomes), CD69 and PD-1, companied with extremely high levels of IL-6, IL-8 in the cerebrospinal fluid and plasma. Patient 2, who showed high fever and seizures and was admitted to the hospital very early in the disease course, received intravenous tocilizumab and subsequently showed a reduction in temperature and a stable conscious state 24 h later. In conclusion, a proinflammatory cytokine storm associated with activated CD4+T cells may cause severe brain pathology in IANE. Tocilizumab may be helpful in treating IANE.

Dysfunction of nuclear receptors(NRs),which are critical for maintaining renal lipid homeostasis,largely contributes to the progression of diabetic nephropathy(DN)by promoting renal lipid accumulation.However,there are few thera-pies in modern medicine that effectively inhibit re-nal lipid accumulation by modulating NRs.In this review,we first summarize recent advances in NRs-mediated renal lipid accumulation in DN.Then,we summarize recent studies on the effects and mech-anisms of Chinese herbal medicines on DN and highlight the effects of Chinese herbal medicines on renal lipid accumulation via NRs.In addition,the advantages and limitations of traditional Chi-nese medicine in the treatment of DN via NRs-me-diated renal lipid accumulation are analyzed,and the modulation of renal lipid accumulation via NRs is emphasized as a promising therapeutic strategy for the treatment of DN.

Objective To explore the performance of routine blood test parameters,bone marrow parameters and the risk factors of leukemia conversion in higher-risk patients with myelodysplastic syndrome(MDS)treated with Bushen Jiedu Huayu Method in the real world.Methods The clinical data of 162 patients with higher-risk MDS who were admitted to the Department of Hematology,Xiyuan Hospital,China Academy of Chinese Medical Sciences from September 2017 to September 2022 were collected,and their clinical data,blood routine parameters,and bone marrow parameters were analyzed.Results A total of 162 higher-risk MDS patients were included,and the overall effective rate of the combination of traditional Chinese and Western medicine treatment,mainly using Bushen Jiedu Huayu Method being 48.8%.Patients with higher-risk MDS who were younger than 70 years old were more likely to obtain curative effect when treated with Bushen Jiedu Huayu Method combined with chemotherapy(P<0.05).After treatment with Bushen Jiedu Huayu Method,PLT levels in higher-risk MDS patients were significantly higher than those before treatment(P<0.05),and PLT levels in the ineffective group increased more significantly(P<0.05).After treatment,the HGB level in the effective group significantly increased(P<0.05).After treatment,the proportion of bone marrow granulocytes,megakaryocytes and lymphocytes in higher-risk MDS patients were significantly higher than those before treatment(P<0.05).Conclusion Bushen Jiedu Huayu Method,mainly using arsenic containing TCM compound,can treat higher-risk MDS.It can increase the HGB content and PLT level of patients,increase the proportion of bone marrow granulocytes,megakaryocytes and lymphocytes,and also play a certain role in reducing the proportion of bone marrow primitive cells,namely demethylation.

Objective:To investigate the clinical efficacy of extracorporeal shock wave (ESWT) combined with stretching training in the treatment of chronic plantar fasciitis.Methods:A prospective case-control study was conducted to include the patients with chronic plantar fasciitis who had been admitted to Department of Orthopaedic Trauma, Nanfang Hospital, Southern Medical University from June 2021 to June 2022. A SPSS random number generator was used to randomize the patients into an experimental group (receiving treatment with ESWT combined with stretching training) and a control group (receiving stretching training only). Shear wave elastography (SWE) was used to quantitatively evaluate the elastic modulus of the plantar fascia. The 2 groups were compared in terms of visual analogue scale (VAS) pain score, plantar fascia thickness, and elastic modulus of the plantar fascia in the patients at 12 weeks after treatment; the correlation between VAS pain score and elastic modulus of the plantar fascia was examined using Spearman analysis in the patients at 12 weeks after treatment.Results:This study included a total of 41 patients (52 feet), 20 males and 21 females with an age of (49.9±8.2) years. There were 16 left sides, 14 right sides and 11 bilateral sides affected. The course of the disease was 7.0 (6.0, 12.0) months. The 2 groups were comparable because there were no significant differences in the general data before treatment between them ( P>0.05). The VAS pain score at 12 weeks after treatment for the experimental group was 1.0 (1.0, 2.0) points, significantly lower than that for the control group [3.0 (2.0, 3.0) points] ( P<0.05). The elastic modulus of the plantar fascia at 12 weeks after treatment for the experimental group was (79.48 ± 17.65) kPa, significantly higher than that for the control group [(57.08 ± 14.16) kPa] ( P<0.05). However, there was no statistically significant difference between the 2 groups in the thickness of the plantar fascia at 12 weeks after treatment ( P>0.05). There was a significant correlation between VAS pain score and elastic modulus of the plantar fascia after 12 weeks of treatment ( r = -0.708, P<0.001). Conclusion:In the treatment of chronic plantar fasciitis, combination of ESWT and stretching training is more effective than stretching training only.
