Recent studies have shown that the physiological homeostasis of oral mucosal cells is regulated by the circadian clock.Dis-ruption or dysfunction of the circadian clock is closely associated with the development of oral squamous cell carcinoma(OSCC).Research based on the circadian clock offers a novel perspective on the pathogenesis and therapeutic strategies for OSCC.However,there is current-ly limited research on this topic,and people generally have insufficient understanding and recognition of the circadian clock.Given the complexity and challenges of circadian clock which is the fourth dimension of medical research,we organize relevant experts based on summarizing the current research results of circadian clock in the pathogenesis and precision diagnosis and treatment of OSCC,combining the scientific principles of the circadian clock's role and their long-term research experience,then summarizes and recommends the con-sensus opinions for the research of circadian clock in the pathogenesis mechanism and precision diagnosis and treatment of human OSCC,with the hope of providing guidance for the basic research and clinical application of circadian clock or circadian rhythm in the pathogene-sis mechanism and precision diagnosis and treatment of oral and maxillofacial squamous cell carcinoma.

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).

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

This study constructed a LHCGR-CRE-luc-HEK293 transgenic cell line according to the activation of the cAMP signaling pathway after recombinant human chorionic gonadotropin binding to the receptor. The biological activity of recombinant human chorionic gonadotropin was assayed using a luciferase assay system. The relative potency of the samples was calculated using four-parameter model. And the method conditions were optimized to validate the specificity, relative accuracy, precision and linearity of the method. The results showed that there was a quantitative potency relationship of human chorinonic gonadotropin (hCG) in the method and it was in accordance with the four-parameter curve. After optimization, the conditions were determined as hCG dilution concentration of 2.5 μg·mL^-1, dilution ratio of 1∶4, cell number of 10 000-15 000 cells/well, and induction time of 6 h. The method had good specificity, relative accuracy with relative bias ranging from -8.9% to 3.4%, linear regression equation correlation coefficient of 0.996, intermediate precision geometric coefficient of variation ranging from 3.3% to 15.0%, and linearity range of 50% to 200%. This study successfully established and validated a reporter gene method to detect hCG biological activity, which can be used for hCG biological activity assay and quality control.

Objective:To explore the effect and safety of mesenchymal stem cell exosome microneedle introduction in the treatment of melasma.Methods:Thirty cases of female patients with stable melasma in the Department of Dermatology, Changsha Meilai Medical Beauty Hospital, aged (36±5) years and with a disease duration of (42.4±20.7) months, from July 2021 to July 2022, were retrospectively included. According to Fitzpatrick skin typing, 23 cases of type Ⅲ and 7 cases of type Ⅳ were included. All patients were locally anesthetized with lidocaine cream for 30 min, and rolled with a 0.5 mm needle in a zigzag pattern with even force, in the order of the right cheek, the left cheek, the forehead, the nose, the mandible, and the upper lip. During the rolling process, 3 ml of MSC exosome medical liquid wound dressing was applied to the facial skin, and after it was fully absorbed, exosome was locally readministered in the area of melasma. Treatment ended with a slight redness at the site of application. 1 MSC exosome wound dressing was appllied as a cold compress for 15 min after treatment. Treatment was given once every 2 weeks for 6 consecutive sessions. All the patients were followed up at 4 and 12 weeks after the last session, and the area and severity index of melasma (MASI) were scored before and after the treatment, the clinical efficiency and patient satisfaction rate and the incidence of adverse reactions were also counted.Results:At 4 and 12 weeks after the end of treatment, the skin color of all 30 patients was brighter than that before treatment, and no recurrence of melasma symptoms seen. At 12 weeks after the end of treatment, the decrease rate of MASI score was 66.1%, among which the decrease rate of MASI score in patients with type Ⅲ melasma was 63.9%, and the decrease rate of MASI score in patients with type Ⅳ melasma was 63.9%. Among the 30 patients, 1 case was cured, 25 cases showed obvious improved, 4 cases were improved, and no cases were ineffective, with an effective rate of 86.7% (26/30). Five patients were very satisfied, 18 patients were satisfied, 6 patients were generally satisfied, and 1 patient was dissatisfied; the patient satisfaction rate was 76.7% (23/30). No serious adverse reactions occurred in all patients.Conclusions:MSC exosome microneedle introduction is safe and effective in the treatment of melasma without serious adverse reactions.

Objective:To evaluate the changes in medical service utilization following the implementation of DRG payment reform in Beijing.Methods:The study collected the home data of inpatient medical records from 15 tertiary general hospitals participating in DRG payment,from April 2021 to October 2022.The data was analyzed before and after the reform,with patients receiving urban employee basic medical insurance as the payment group,and other populations as the control group.A propensity score matching-difference-in-differences model was used to analyze the changes in average length of stay,average cost per hospitalization,and re-outpatient rate before and after the reform.Results:The 15 tertiary general hospitals experienced a downward trend in average days of stay and average cost per hospitalization.However,The changes in outpatient revisits rate within 30 days before admission and hospital revisits rates within 30 days after discharge were found to be not significant after the implementation of DRG payment.Conclusion:The implementation of DRG payment did not result in a transfer of inpatient medical service demand to outpatient service.However,it is important to note that the long-term effect of the reform needs further evaluation.

Purpose To analyze the imaging features of juvenile xanthogranuloma (JXG) in children and to improve the diagnostic level of JXG. Materials and Methods The clinical and imaging data of 15 children with JXG confirmed by menstrual biopsy or surgical pathology from January 2011 to December 2023 in Hunan Children's Hospital were retrospectively analyzed. 13 cases underwent CT examinations and 7 cases underwent MRI examinations,of which 5 underwent both MRI and CT examinations. The type,number,involved site,lesion signal,density and enhancement characteristics of JXG were observed and analyzed. Results Of the 15 children with JXG,7 cases were systemic. It involves the central nervous system (5 cases,including pineal region,choroid plexus,cranial sublamina,middle cranial fossa and spinal canal),mastoid process (1 case),liver (3 cases),kidney (3 cases),pancreas (1 case) and lung (2 cases),mainly manifested as single or multiple nodular,mass or patchy lesions in different organs. On MRI,the lesions showed slightly higher or lower or mixed signals on T1WI,low/slightly lower or higher or mixed signals on T2WI,unrestricted or limited diffusion,and significantly enhanced or slightly enhanced enhancement. On CT,the lesions showed patchy,clumpy or nodular low-density or high-density shadows,and the enhancement was mild to moderate uneven enhancement or obvious enhancement. 8 patients with simple skin type showed nodular shadow of subcutaneous soft tissue,equal or slightly low signal on T1WI,slightly low/low signal on T2WI and obvious enhancement. CT showed a slightly low/equal/slightly high density image,and the enhancement showed a slightly enhanced/significantly enhanced image. Conclusion JXG mainly presents as single or multiple nodules and clumps in subcutaneous soft tissues and/or various organs,with increased signal on T1WI,decreased signal on T2WI,decreased or increased diffusion and obvious enhancement. The CT and MRI manifestations of JXG have certain characteristics.
