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).

Osteoarthritis (OA), the most prevalent joint disease of late life, is closely linked to cellular senescence. Previously, we found that the senescence of fibroblast-like synoviocytes (FLS) played an essential role in the degradation of cartilage. In this work, single-cell sequencing data further demonstrated that cartilage acidic protein 1 (CRTAC1) is a critical secreted factor of senescent FLS, which suppresses mitophagy and induces mitochondrial dysfunction by regulating SIRT3 expression. In vivo, deletion of SIRT3 in chondrocytes accelerated cartilage degradation and aggravated the progression of OA. Oppositely, intra-articular injection of adeno-associated virus expressing SIRT3 effectively alleviated OA progression in mice. Mechanistically, we demonstrated that elevated CRTAC1 could bind with NRF2 in chondrocytes, which subsequently suppresses the transcription of SIRT3 in vitro. In addition, SIRT3 reduction could promote the acetylation of FOXO3a and result in mitochondrial dysfunction, which finally contributes to the degradation of chondrocytes. To conclude, this work revealed the critical role and underlying mechanism of senescent FLSs-derived CRTAC1 in OA progression, which provided a potential strategy for the OA therapy.

Acetabular fracture is a kind of intra-articular fracture with complicated anatomy and difficult treatment. The core of treatment lies in anatomic reduction and strong fixation. The low incidence and intricate anatomical structure present significant challenges for treatment of acetabular fractures. In recent years, significant progress has been made in the treatment of acetabular fractures, particularly in surgical approaches, robotic-assisted technology, the application of tranexamic acid, and treatment strategies for elderly patients, providing new therapeutic options. This article reviews the latest progress in acetabular fracture treatment research.

Objective To investigate the clinical efficacy of Jianpi Qushi Method(a spleen-invigorating and dampness-removing approach)combined with Chinese herbal fumigation therapy in treating seborrheic alopecia of spleen deficiency with dampness-accumulation type and to observe its influence on hormone levels.Methods The observation was carried out in 104 patients with spleen deficiency with dampness-accumulation type of seborrheic alopecia,who admitted to the Department of Dermatology at Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from January 2023 to February 2024.The patients were equally randomized into a trial group and a control group,with 52 cases in each group.The control group received oral administration of Finasteride Tablets,while the trial group was additionally treated with Jianpi Qushi Method combined with Chinese herbal fumigation therapy for 3 months.Serum hormone levels,hair loss scores,clinical symptom scores(including greasy hair,pruritus,scaling,and growth of new hair),and trichoscopic parameters of the hair in the two groups were assessed before and after treatment.After treatment,the clinical efficacy and adverse reactions in the two groups were also evaluated.Results(1)After 3 months of treatment,the total effective rate in the trial group was 94.23％(49/52)and that in the control group was 73.08％(38/52).The trial group demonstrated significantly superior efficacy compared to the control group(tested by chi-square test,P<0.01).(2)After treatment,both groups exhibited a significant decrease in serum testosterone level(P<0.05)and a significant increase in serum estradiol level(P<0.05)compared to those before treatment.Notably,the trial group showed a more pronounced reduction in testosterone and a greater elevation in estradiol than the control group(P<0.01).(3)Both groups displayed a significant reduction in hair loss scores after treatment(P<0.05),and the trial group achieved a markedly greater decrease than the control group(P<0.01).(4)After treatment,the clinical symptom scores for greasy hair,pruritus,scaling,and growth of new hair significantly decreased in both groups compared to those before treatment(P<0.05).And the trial group exhibited significantly greater improvements in the scores of all symptoms than the control group(P<0.01).(5)After treatment,both groups showed a significant increase in hair density(hairs/cm2)and count of upright regrowing hair(P<0.05),along with a significant decrease in vellus hair count,hair count in the single hair follicle,and count of perifollicular keratosis(P<0.05).The trial group demonstrated significantly superior improvements in all trichoscopic parameters compared to the control group(P<0.01).(6)No significant adverse reactions were observed in either group during the treatment period,indicating a favorable safety profile for both therapeutic approaches.Conclusion Jianpi Qushi Method combined with Chinese herbal fumigation therapy exerts significant efficacy in treating seborrheic alopecia of spleen deficiency with dampness-accumulation type.The combined therapy is effective on regulating hormone levels,promoting hair regeneration,and alleviating symptoms such as greasy hair and pruritus,and demonstrates favorable safety.

Objective To investigate the diagnostic value of 4 novel inflammatory markers related to routine blood tests,namely neutrophil-to-lymphocyte ratio(NLR),red blood cell distribution width(RDW),hemoglobin-to-RDW ratio(HRR)and systemic immune-inflammation index(SII),in elderly patients with chronic cardiovascular disease(CVD)complicated with frailty.Methods Retrospectively analyze 110 patients with chronic stable CVD who were hospitalized in the cadre ward of cardiovascular medicine at the Air Force Characteristic Medical Center from January 2022 to June 2023.According to the assessment results of the Fried scale,they were divided into three groups:non-frailty group(Fried score=0,n=30),the pre-frailty group(Fried score 1 or 2,n=40)and frailty group(Fried score≥3,n=40).The differences in general information,the impairment rate of daily living activities,miniature nutritional assessment-short form(MNA-SF)scores,mini-mental state examination(MMSE)scores,and the indicators such as NLR,RDW,HRR,and SII among the three groups were compared.Spearman rank correlation was used to analyze the correlation between NLR,RDW,HRR,SII and frailty scores as well as each frailty indicator.Multivariate logistic regression analysis was performed to identify the independent risk factors for frailty in elderly patients with chronic CVD,and the receiver operating characteristic(ROC)curve was used to assess the clinical diagnostic value of NLR and HRR in elderly patients with chronic CVD complicated with frailty.Results Compared with non-frailty group and pre-frailty group,patients in frailty group were older,with higher impaired rates of daily living activities,NLR,RDW,and SII,and lower MNA-SF scores,MMSE scores,and HRR,and differences were statistically significant(P<0.05).Spearman rank correlation analysis showed that the frailty score was positively correlated with NLR(rs=0.354,P<0.001),and RDW(rs=0.448,P<0.001),negatively correlated with HRR(rs=-0.232,P=0.024),and had no significant correlation with SII(rs=0.144,P=0.167).Further analysis of the correlation between the above novel inflammatory markers and the 5 components of frailty showed that NLR was positively correlated with fatigue(rs=0.228,P=0.017),slowed walking speed(rs=0.299,P<0.001),and low physical function(rs=0.319,P<0.001);RDW was positively correlated with decreased grip strength(rs=0.321,P<0.001),slowed walking speed(rs=0.422,P<0.001),and low physical function(rs=0.246,P=0.001);and HRR was negatively correlated with slowed walking speed(rs=-0.230,P=0.025),and low physical function(rs=-0.299,P=0.003).Multivariate logistic regression analysis showed that MNA-SF score(OR=0.577,95%CI 0.342-0.973)was an independent protective factor for pre-frailty in elderly patients with chronic CVD(P<0.05);NLR(OR=7.866,95%CI 1.101-56.185)was an independent risk factor for frailty,while HRR(OR=0.344,95%CI 0.120-0.983)and MNA-SF score(OR=0.292,95%CI 0.146-0.580)were independent protective factors for frailty in elderly CVD patients(P<0.05).The area under the ROC curve of NLR and HRR for diagnosing frailty in elderly patients with chronic CVD were 0.778 and 0.749,respectively.Conclusion NLR and HRR have high clinical diagnostic value for frailty in elderly patients with chronic CVD,and are expected to become effective inflammatory markers for screening elderly patients with chronic CVD complicated with frailty.

Backgrounds Insomnia is frequent in schizophrenia and is found to be negatively affected by stressful life events,psychotic symptoms and depressive disorder,while the relationship among the four remains understudied in community-dwelling patients with schizophrenia.Objective To analyze the effect of stressful life events on insomnia in community-dwelling patients with schizophrenia,and to explore the mediation effect of psychotic symptoms and depression,so as to provide references for the intervention of insomnia in community-dwelling patients with schizophrenia.Methods From April to June 2023,a sample of 1 105 patients with schizophrenia attending 48 community health centers in Chengdu,Sichuan province and fulfilling the International Classification of Diseases,tenth edition(ICD-10)diagnostic criteria were included.All subjects were assessed using Stressful Life Event Scale(SLEs),Athens Insomnia Scale(AIS),Psychosis Screening Questionnaire(PSQ),and Patient Health Questionnaire Depression Scale(PHQ-9).Spearman correlation analysis was used to determine the correlation among the scales.Then the mediation model was constructed using Smart PLS 4.0,and tested with partial least squares algorithm and Bootstrap techniques.Results 332 patients(30.05%)with community schizophrenia were found to have insomnia.AIS scores in patients with schizophrenia were positively correlated with the scores on SLEs,PSQ and PHQ-9(r=0.165,0.322,0.554,P<0.01).Stressful life events indirectly contributed to insomnia through both separate mediation path and chained mediation path of psychotic symptoms and depressive disorder,and the indirect effect size of 0.102,0.372 and 0.190 was obtained,accounting for 10.46%,38.15%and 19.49%,respectively.Conclusion The stressful life events not only directly exert an impact on insomnia,but also indirectly contribute to insomnia through both the separate and chained mediation effect of psychotic symptoms and depressive disorder.

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.

Objective:To study influence of exercise rehabilitation based on psycho-cardiology medical model on pa-tients with coronary heart disease(CHD)after percutaneous coronary intervention(PCI).Methods:A total of 164 CHD patients undergoing PCI in our hospital were randomly and equally divided into routine nursing group and exer-cise rehabilitation group(received exercise rehabilitation based on psycho-cardiology medical model based on rou-tine nursing group).Both groups were intervened for six months.General clinical data,score of somatic symptoms scale(SSS),cardiac function indexes:LVEF and LVEDV,6min walking distance(6MWD)and score of 36-item short-form heath survey(SF-36)were compared between two groups.Results:During follow-up,there were three cases lost in routine nursing group,and two cases lost and four cases stopped follow-up in exercise rehabilita-tion group.Compared with routine nursing group,six months after intervention,there were significant reductions in SSS score[(33.97±5.76)scores vs.(25.76±4.79)scores]and LVEDV[(125.33±16.14)ml vs.(119.53± 16.82)ml],and significant rise in LVEF[(56.28±4.46)％vs.(59.28±4.90)％],6MWD[(410.42±20.08)m vs.(439.69±20.66)m],scores of physical functioning[(19.20±4.22)scores vs.(23.76±3.98)scores],bodily pain[(7.42±1.99)scores vs.(8.84±1.94)scores],general health[(16.42±4.73)scores vs.(19.09±4.37)scores],vitality[16.0(7.0)scores vs.19.0(6.8)scores],role-emotional[(4.86±1.10)scores vs.(5.18± 0.86)scores],mental health[20.0(5.0)scores vs.24.0(8.8)scores]of SF-36 in exercise rehabilitation group(P＜0.05 or＜0.01).Conclusion:Exercise rehabilitation based on psycho-cardiology medical model can signifi-cantly improve cardiac function and psychological status,and improve quality of life in patients with coronary heart disease after PCI.

Objective To investigate the impact and mechanism of efaproxiral (RSR13),a hemoglobin allosteric agent,on lung injury in rats caused by explosion-induced shock waves in plateau areas. Methods Eighty-two healthy male SD rats (8-week-old,transferred from an altitude of 2 880 m to 4700 m within 6 h)were randomly divided into blast injury group and RSR13+blast injury group (intraperitoneal injection of 150 mg/kg RSR132 h before explosion).Sixty rats were positioned at 5 m from the explosion source and divided into 5-m blast injury group (n=30)and 5-m RSR13+blast injury group (n=30). Additionally,16 rats were positioned at 6 m from the explosion source and then assigned into 6-m blast injury group (n=8)and 6-m RSR13+blast injury group (n=8).The left 6 rats served as control (n=6).Survival outcomes of each rat group positioned 5 m from the explosion source were observed over a 24-hour period.HE staining was used to evaluate the pathological score of the surviving rats positioned at 6 m from the explosion source in 24 h after explosion,along with arterial blood gas analysis.The contents of glutathione (GSH),malondialdehyde (MDA ) and superoxide dismutase (SOD ) in the lung tissues were determined by colorimetry.Western blotting was conducted to measure the expression levels of cleaved caspase-3 and occludin in the lung tissue.Results RSR13 pretreatment increased the survival rate immediately after explosion (93.3％ vs 46.7％,P<0.01 )and at 1 h after explosion (86.7％ vs 46.7％,P<0.01 )in plateau areas of 5 m from the explosion source.At high altitude,RSR13 pretreatment reduced the pathological score of lung injury in rats 6 m away from the explosion source (8.27±0.93 vs 13.70±0.78,P<0.01 ),but had no significant effect on the results of arterial blood gas analysis in rats with lung blast injury (P>0.05 ).In addition,RSR13 pretreatment also increased GSH content (40.27±12.47 vs 22.62±10.88 μg/g,P<0.05),but showed no obvious effect on MDA content and SOD activity (P>0.05 ),decreased the protein level of cleaved caspase-3 (P<0.01 )and increased that of occludin (P<0.05 )in the lung tissues.Conclusion RSR13 exerts significant protective effect on lung injury in rats caused by explosion-induced shock waves in high-altitude environment,which may be related to its increasing antioxidant capacity,reducing cell apoptosis and decreasing barrier permeability of lung ventilation.

Mitral valve prolapse is one of the common causes of mitral regurgitation.Mitral valve prolapse complicated with leaflet cleft is rare in clinical practice,which most often undergo surgical mitral valve repair or mitral valve replacement.We report a case of mitral valve prolapse with posterior leaflet cleft treated by transcatheter edge-to-edge mitral valve repair,in order to provide a model for similar cases.
