BACKGROUND:Osteoarthritis is pathologically characterized by progressive degeneration of the articular cartilage and abnormal deformation of the subchondral bone.In recent years,with the deepening of medical research,it has been found that the mitogen-activated protein kinases(MAPK)signaling pathway has a regulatory role in inflammatory cell infiltration,inflammatory factor release,and chondrocyte proliferation,which is particularly important for the treatment of osteoarthritis.OBJECTIVE:To briefly review the main research progress in the mechanism of MAPK signaling pathway regulating osteoarthritis in recent years,aiming to provide new ideas for the treatment of osteoarthritis.METHODS:CNKI,WanFang and PubMed databases were searched for relevant literature using the search terms of"mitogen-activated protein kinases,osteoarthritis,extracellular signal-regulated MAP kinases,p38 mitogen-activated protein kinases,JNK mitogen-activated protein kinase"in Chinese and English.Relevant literature published from January 2019 to November 2024 was searched,and 108 articles were finally included for summary analysis.RESULTS AND CONCLUSION:(1)Various stimuli inside and outside the cells activate the MAPK signaling pathway,regulate gene transcription and protein synthesis,and promote the release of inflammatory factors,such as tumor necrosis factor-α,interleukin-1β,and interleukin-6.The release of these inflammatory factors aggravates the progression of osteoarthritis.(2)The active ingredients of traditional Chinese medicine,mainly saponins and flavonoids,as well as Chinese herbal formulas and preparations with the main effects of activating blood circulation and removing blood stasis,tonifying the liver and kidney,can play a therapeutic role in osteoarthritis by inhibiting the MAPK signaling pathway,regulating the release of matrix metalloproteinases,balancing the homeostatic state of osteogenesis and osteoblastogenesis,attenuating the synovial inflammation,decreasing the release of inflammatory factors and inflammatory vesicles,decreasing cellular pyroptosis,promoting autophagy,and ameliorating oxidative stress.(3)Although traditional Chinese medicine has become popular in the treatment of osteoarthritis by virtue of its own advantages of multi-components,multi-targets,multi-pathways,and low side effects,the use of MAPK signaling pathway to guide the treatment of individual osteoarthritis is the difficulty of the technology,which needs to be continuously researched and explored.(4)Therefore,further development of relevant herbal inhibitors that can modulate the MAPK signaling pathway may be a potential drug strategy for the treatment of osteoarthritis in the future.

BACKGROUND:
Disease-modifying therapies have been approved for the treatment of relapsing multiple sclerosis (RMS). The present study aims to examine the safety of teriflunomide in Chinese patients with RMS.
METHODS:
This non-randomized, multi-center, 24-week, prospective study enrolled RMS patients with variant (c.421C>A) or wild type ABCG2 who received once-daily oral teriflunomide 14 mg. The primary endpoint was the relationship between ABCG2 polymorphisms and teriflunomide exposure over 24 weeks. Safety was assessed over the 24-week treatment with teriflunomide.
RESULTS:
Eighty-two patients were assigned to variant ( n = 42) and wild type groups ( n = 40), respectively. Geometric mean and geometric standard deviation (SD) of pre-dose concentration (variant, 54.9 [38.0] μg/mL; wild type, 49.1 [32.0] μg/mL) and area under plasma concentration-time curve over a dosing interval (AUC tau ) (variant, 1731.3 [769.0] μg∙h/mL; wild type, 1564.5 [1053.0] μg∙h/mL) values at steady state were approximately similar between the two groups. Safety profile was similar and well tolerated across variant and wild type groups in terms of rates of treatment emergent adverse events (TEAE), treatment-related TEAE, grade ≥3 TEAE, and serious adverse events (AEs). No new specific safety concerns or deaths were reported in the study.
CONCLUSION:
ABCG2 polymorphisms did not affect the steady-state exposure of teriflunomide, suggesting a similar efficacy and safety profile between variant and wild type RMS patients.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the value of 24 h urinary aldosterone(24 h-UAC) measurement by liquid chromatography-tandem mass spectrometry(LC-MS/MS) in the subtype classification of primary aldosteronism(PA).Methods:A total of 86 patients with PA, including 51 with unilateral primary aldosteronism(UPA) and 35 with bilateral primary aldosteronism(BPA), were enrolled in the Department of Endocrinology and Metabolism at West China Hospital between January 2018 and December 2022. Plasma aldosterone concentration(PAC), plasma renin concentration(PRC) and 24 h-UAC were measured by LC-MS/MS. 24-hour urinary electrolytes and 24-hour urinary creatinine(24 h-UCR) were also measured. The diagnostic value of 24 h-UAC in PA subtype classification was evaluated using receiver operating characteristic(ROC) curve analysis. Multivariate logistic regression analysis was conducted with PA subtypes as the dependent variable(UPA=1, BPA=0) to establish a diagnostic model for differentiating unilateral from bilateral lesions, and its performance was compared with published Chinese classification models. Results:There were no statistical differences between the UPA and BPA groups in terms of age, gender, BMI, systolic and diastolic blood pressure, 24 h urinary potassium, sodium, chloride, 24 h-UCR and PRC( P<0.05). The lowest plasma potassium level was significantly lower in the UPA group than in the BPA group, while PAC, 24 h-UAC, aldosterone-renin ratio(ARR), and 24 h-UAC/UCR were significantly higher( P<0.05). The detection rate of typical adenomas on imaging also showed a significant difference between the two groups( P<0.05). The area under the ROC curve(AUC) of 24 h-UAC for differentiating UPA from BPA was 0.829(95% CI 0.733-0.902), with an optimal cut-off value of 15.4 μg/24 h, yielding a sensitivity of 68.63% and a specificity of 88.57%( P<0.001). At a cut-off value of 24.5 μg/24 h, specificity reached 100%, with a sensitivity of 27.45%. Multivariate analysis indicated that a combined model incorporating 24 h-UAC, the lowest plasma potassium level, and imaging findings of typical adenomas significantly improved diagnostic accuracy for PA subtyping, achieving a specificity of 91.43%. Compared with the existing Chinese modified Küpers scoring model and CONPASS prediction model, this model demonstrated higher diagnostic efficiency, a lower missed diagnosis rate, and a misdiagnosis rate intermediate between the two. Conclusion:The 24 h-UAC in UPA patients is significantly higher than in BPA patients, making it a valuable marker for PA subtype classification. A predictive model combining 24 h-UAC, the lowest plasma potassium level, and imaging evidence of typical adenomas demonstrated high diagnostic accuracy for PA subtype classification and may provide valuable guidance for clinical decision-making.

Objective:The arrival of the big data era has accelerated the development of information technology in the healthcare sector. Internationally, developed countries such as the United States, the United Kingdom, and the European Union have taken pioneering initiatives in data openness. Since 2015, China has rapidly promoted the application of big data through policy layout. This study aims to help the open and shared development of healthcare big data in our country by investigating the status quo of open and shared healthcare big data at home and abroad.Methods:Through literature research and information integration, this study summarized the development history and current situation of open and sharing health and medical big data at home and overseas, analyzed related problems and challenges, and proposed countermeasures and development suggestions.Results:The open sharing of health and medical big data in developed countries and regions abroad had made outstanding achievements in legislation, standard formulation, platform construction, etc. The domestic policy layout was relatively perfect, and the relevant construction was being actively promoted. Problems and challenges still existed in five aspects, including privacy security, data format standards, data quality, laws and regulations, and property rights and interests.Conclusions:Combined with the problems found in the current research process, the following countermeasures and development suggestions are proposed for domestic health and medical big data open sharing: establish a privacy protection mechanism to ensure data security, unify data standards to improve data interoperability, build a data quality control system to ensure data accuracy, improve laws and regulations to standardize data sharing behavior, clarify the ownership of interests and protect intellectual property rights.

BackgroundNon-suicidal self-injury (NSSI) represents a prevalent clinical feature among adolescent patients with major depressive disorder. Existing research has suggested that interoceptive awareness might be linked to NSSI behaviors, but investigations into this association among adolescent patients with major depressive disorders remain limited. ObjectiveTo elucidate the correlation between NSSI behaviors and interoceptive awareness in adolescent patients with major depressive disorder, and to identify influencing factors of NSSI behaviors, in order to provide clinical prevention and treatment strategies. MethodsA total of 125 adolescent patients who met the diagnostic criteria for major depressive disorder as outlined in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) were recruited from the Fourth People's Hospital of Hefei from December 2022 to June 2024. These participants were subsequentially categorized into NSSI behavior group (n=60) and non-NSSI behavior group (n=65) based on the presence or absence of NSSI behaviors. Additionally, a control group comprising 40 healthy adolescents was concurrently assembled for comparison. The Hamilton Depression Scale-17 item (HAMD-17) was used to assess the depressive symptoms of adolescent patients with major depressive disorder, and the Multidimensional Assessment of Interoceptive Awareness version 2- Chinese (MAIA-2) was used to evaluate the interoceptive awareness level of all subjects. Pearson correlation analysis was employed to examine the correlation between HAMD-17 scores and MAIA-2 scores. Binary Logistic regression analysis was conducted to identify the influencing factors of NSSI behaviors in adolescent patients. Then the receiver operating characteristic (ROC) curve was drawn to verify the predictive efficacy of MAIA-2 scores for NSSI behaviors in adolescent patients with major depressive disorder. ResultsSignificant differences were identified across six MAIA-2 subscales (noticing, not distracting, not worrying, attention regulation, emotional awareness, body listening) and the MAIA-2 total score among the three groups (F=18.475, 20.631, 6.044, 5.621, 18.456, 12.889, 12.741, P<0.01). Correlation analysis underscored a notable negative correlation between the MAIA-2 total score and the HAMD-17 total score, as well as its scores on subscales pertaining to weight and cognitive impairment factors(r=-0.315, -0.203, -0.278, P<0.05). Binary Logistic regression results indicated that longer disease duration (OR=1.112, 95% CI: 1.043–1.206) and higher HAMD-17 total score (OR=2.071, 95% CI: 1.361–3.150) were risk factors for NSSI behavior in adolescents with depressive disorder, while a higher MAIA-2 total score was a protective factor against NSSI behavior in this population (OR=0.580, 95% CI: 0.407–0.828). The MAIA-2 total score demonstrated a relatively high predictive value for NSSI behaviors in adolescent patients with major depressive disorder (AUC=0.793). ConclusionNSSI behaviors in adolescent patients with major depressive disorder are closely related to the disease course, severity of depression, and specific interoceptive awareness patterns. Moreover, interoceptive awareness may serve as a predictive indicator for the occurrence of their NSSI behaviors.

Objective:To design a morning quality assurance method for pencil-beam scanning proton system to achieve integrated measurement of multiple parameters.Methods:A functionally partitioned morning check phantom was designed and manufactured, which was fixed to a specific position on the treatment bed with a 3D-printed clip, along with the two-dimensional matrix ionization chamber, for consistency checks of proton field and beam-related parameters. Additionally, a groove for an imaging phantom was reserved on one side of the clip for the functional check of the onboard imaging guidance system. The sensitivity and specificity of the aforementioned morning check method were tested, demonstrating its effectiveness. The morning check data from a rotating beam treatment room at the Hefei Ion Medical Center over a continuous period of 7 months (126 d) were analyzed. The output, field flatness, symmetry, field size and the duration of morning check were observed.Results:The results showed that the changes in the output, field flatness, and symmetry were all within 1%, the change in the field size was within 0.5 mm, and the range variations for both 155 MeV and 240 MeV energy levels were within 1 mm. The changes in the spot size for the four energy levels of 100 MeV, 130 MeV, 160 MeV, and 190 MeV were all within 2%, and the spot position deviations were within 1.5 mm. The entire morning check process could be completed within 20 min.Conclusions:The morning check method designed and manufactured in this study specifically for pencil-beam scanning proton therapy can efficiently and integrally measure various proton system parameters and can be used as an implementation method for clinical proton therapy morning check.

Objective To investigate the therapeutic effects of copper-doped barium titanate(BaCuTiO4)piezoelectric materials combined with low-intensity pulsed ultrasound(LIPUS)to activate their piezoelectric-catalytic synergistic effect for treating implant-associated infections.Methods BaCuTiO4 coatings were synthesized on the surface of Ti-6Al-4V substrates using a hydrothermal method,and their surface morphology was characterized by scanning electron microscopy.The piezoelectric characteristics of the coatings were analyzed using a piezoresponse force microscope.An in vitro biofilm model of methicillin-resistant staphylococcus aureus(MRSA)was used,with barium titanate(BaTiO3)coatings serving as the control group.Under LIPUS intervention(1.0 W/cm2,1 MHz,10 min),the bacterial viability was assessed using colony counting to evaluate the antibacterial performance of the BaCuTiO4 coatings.Confocal microscopy was used to observe biofilm viability in different groups,assessing the biofilm removal capability of the coatings.Reactive oxygen species(ROS)generation in each group was detected using Rhodamine b as a probe to evaluate the catalytic efficiency of the coatings in generating ROS.Results Copper doping significantly reduced the piezoelectric coefficient of the coating(from 17.7 pm/V to 7.8 pm/V),bringing its piezoelectric performance closer to the requirements of natural bone tissues.Under LIPUS activation,the BaCuTiO4 coatings increased the generation efficiency of reactive oxygen species by 67.5%and effectively disrupted and removed biofilms formed by MRSA,achieving an antibacterial rate of 90.5%.Conclusions The BaCuTiO4 coatings achieve efficient antibacterial and biofilm-clearing functions through a piezoelectric-catalytic synergistic mechanism.Their piezoelectric properties are well-matched with natural bone tissues,promoting implant osseointegration.
