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).

Depression is a prevalent mental illness worldwide, its multifaceted pathogenesis is still in the exploratory stage. MicroRNA (miRNA), as a crucial epigenetic regulator, plays an important role in depression. miR-124 is one of the most abundant miRNAs in the central nervous system including neurons and microglia, and involved in various biological events like neuron development and differentiation, synaptic and axonal growth, neural plasticity, inflammation and autophagy. Recent studies have reported abnormal expression of miR-124 in both depression patients and animal models. Most of the studies showed that miR-124 is upregulated in the hippocampus or prefrontal cortex in stress-induced rodent depression animal models such as CUMS, CSDS, CORT, CRS and LH but some evidence for divergence. Upregulation of miR-124 expression may be involved in depression-like behavior via CREB/BDNF/TrkB pathway, GR pathway, SIRT1 pathway, apoptosis and autophagy pathways by directly targeting these genes including Creb, Bdnf, Sirt1, Nr3c1, Ezh2 and Stat3. The downregulation of miR-124 expression in neurons is mainly involved in the neurogenesis and neuroplasticity impairments in depression by targeting the Notch signaling pathway and DDIT4/TSC1/2/mTORC1 pathway. The downregulation of miR-124 expression also was found in the activated microglia in the stress-induced models, and resulted in neuroinflammation. In summary, the abnormal expression of miR-124 in the brain of depression-related models and its related mechanisms are complex and even contradictory, and still need further research. This review provides a summary of the research progress of miR-124 in depression.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

AIM: To investigate the effect of phacoemulsification with steep meridian transparent corneal incision on visual function, corneal astigmatism and tear film changes.METHODS: A total of 106 cataract patients(106 eyes)who underwent phacoemulsification in our hospital from January 2019 to December 2020 were selected as research objects, and they were divided into observation group and control group according to the operation mode: with 51 patients in the observation group who were treated with steep meridian transparent corneal incision, and 55 patients in the control group who were treated with transnasal transparent corneal incision. The changes of visual function, corneal astigmatism and tear film between the two groups were compared before operation and at 1wk, 1 and 3mo after operation.RESULTS: There was no statistical difference between the operation of two groups(all P>0.05). The visual acuity was significantly improved at 1wk, 1 and 3mo after operation, and it was better in the observation group than that in the control group.

External apical root resorption is among the most common risks of orthodontic treatment, and it cannot be completely avoided and predicted. Risk factors causing orthodontic root resorption can generally be divided into patient- and treatment-related factors. Root resorption that occurs during orthodontic treatment is usually detected by radiographical examination. Mild or moderate root absorption usually does no obvious harm, but close attention is required. When severe root resorption occurs, it is generally recommended to suspend the treatment for 3 months for the cementum to be restored. To unify the risk factors of orthodontic root resorption and its clinical suggestions, we summarized the theoretical knowledge and clinical experience of more than 20 authoritative experts in orthodontics and related fields in China. After discussion and summarization, this consensus was made to provide reference for orthodontic clinical practice.

The proximal medial column of the humerus is a continuous cortical region in the inner and lower part of the humerus head, which has attracted more and more attention in clinical and scientific research since it was proposed. It has been shown to increase the stability of internal fixation, maintain the height of the humeral head to prevent varus, and reduce the risk of screw penetration. Biomechanical studies have also shown that the medial column has an outstanding performance in increasing the stiffness, torsion resistance, and shear resistance of the locking plate. Although it has many benefits, there is no unified definition of its concept and specific region, and the existing classification does not include the medial column, therefore more researches are required to provide supporting information. The methods of medial column reconstruction mainly include locking plate combined with talus screw, locking plate combined with bone grafting, internal and external double plate combined support, locking plate combined with bone cement, and humeral cage. These methods have their own characteristics, however they will increase the cost of surgery and bring new complications. How to determine the best way of reconstruction is one of the focuses of future research. In this review, the concept of the proximal medial humerus column, the role of maintaining internal fixation, the role of biomechanics and the reconstruction methods are reviewed.

Exhaled breath condensate (EBC) was analyzed by gas chromatography-mass spectrometry (GC-MS / MS) in childhood asthma and healthy control, aiming to find the potential markers of EBC in children with asthma, and provide a scientific reference for its pathogenesis and early screening. EBC samples were collected from 21 asthmatic children (age (8. 2 ±1. 6) years) and 17 healthy children ( age (8. 1 ±1. 3) years). GC-MS / MS was used to obtain the full scan data of chemical components. Cluster analysis was performed on the two groups of metabolites by principal component analysis (PCA), and potential biomarkers were found using Metaboanalyst 3. 0 attributable metabolic pathways. The results showed that the EBC metabolic maps of asthmatic group and normal group were very different, and eight endogenous potential biomarkers were identified, suggesting that starch and sucrose metabolism, lysine degradation, aminoglycan nucleoside metabolism, phenylalanine metabolism may play important roles in the development of asthma in children.
