Osteoarthritis （OA） and stroke are common clinical diseases that reduce patients' quality of life and place a burden on families and society. Ruyi Zhenbaowan， a classic prescription in Tibetan medicine， have the functions of clearing heat， awakening the brain and opening orifices， relaxing tendons and promoting meridian circulation， and eliminating yellow water. Clinically， they are used to treat osteoarthritis， post-stroke sequelae， neuropathic pain， and other related conditions. Modern pharmacological studies have demonstrated their anti-inflammatory， analgesic， and nerve-repairing effects. However， current research remains insufficient regarding the appropriate indications， timing， and efficacy of this medicine in treating relevant diseases. To enhance clinicians' understanding of this medicine and promote its standardized and rational clinical use， a panel of national experts， including clinical specialists， Tibetan medicine practitioners， pharmacologists， and methodologists， formulated this consensus based on clinical experience and evidence-based practice. The Cochrane systematic review framework， the Grading of Recommendations Assessment， Development and Evaluation （GRADE） system， and the nominal group method were employed to generate seven graded recommendations and 19 consensus-based suggestions. These recommendations clearly define the key points in the clinical application of Ruyi Zhenbaowan， including therapeutic indications， dosage and administration， treatment duration， and medication safety. The consensus specifically addresses the clinical efficacy， appropriate timing of administration， dosage strategies， treatment cycles， and combination medication strategies for treating osteoarthritis and stroke and provides an overview of safety considerations. The aim is to provide standardized guidance for hospitals and healthcare institutions nationwide to ensure the rational application of Ruyi Zhenbaowan in the treatment of osteoarthritis and stroke， reduce medication-related risks， and further leverage its clinical advantages. This consensus has been approved and issued by the China Association of Chinese Medicine， with the standard number GS/CACM 369-2024.

Objective: To explore the causal association between micronutrients and irritable bowel syndrome (IBS) using a Mendelian randomization (MR) method, so as to provide the evidence for formulating prevention and treatment measures for IBS. Methods: Genome-wide association studies (GWAS) summary data for 14 micronutrients (copper, selenium, zinc, iron, magnesium, calcium, potassium, folate, vitamin C, vitamin D, vitamin E, vitamin B6, vitamin B12, and carotene) were collected from the MRC Integrative Epidemiology Unit at the University of Bristol GWAS data and the UK Biobank data. GWAS data for IBS were obtained from the FinnGen R10 database. A bidirectional two-sample MR analysis was conducted to assess the causal relationships between micronutrients and IBS, with the inverse-variance weighted method as the primary analytical approach. Heterogeneity among instrumental variables was evaluated using Cochran's Q test. Horizontal pleiotropy was assessed via MR-Egger regression and the MR-PRESSO test. The robustness of the results was examined using leave-one-out and funnel plot. Results: Forward MR analysis revealed a statistically significant association between vitamin B12 and IBS (OR=1.523, 95%CI: 1.093-2.213), while no significant associations were observed for the other 13 micronutrients (all P>0.05). Reverse MR analysis showed no significant association between IBS and any of the 14 micronutrients (all P>0.05). Sensitivity analyses revealed no evidence of heterogeneity or horizontal pleiotropy among the instrumental variables (all P>0.05). The robustness of the findings was supported by leave-one-out and funnel plot. Conclusion Higher vitamin B12 level is associated with an increased risk of IBS, but no reverse causal relationship between vitamin B12 and IBS has been found.

Objective:The clinical symptoms of children with global developmental delay (GDD) were analyzed to provide the scientific basis for the intervention of children with GDD.Methods:The results of the neuro-psychobehavioral scale were collected from 32 511 children with GDD from June 2020 to November 2023. Inclusion criteria: Children diagnosed with GDD according to the Diagnostic and Statistical Manual of Mental Disorders-V, ages 0.0 to 4.9 years. Exclusion criteria: children with common hearing impairment and visual impairment. The Chi-square tests were used for statistical analysis.Results:There were more boys than girls with GDD in outpatient clinics (68.2% vs. 31.8%). Among the children, the proportion of developmental delay in 5, 4, 3, and 2 domains was 31.1%, 23.4%, 22.9% and 22.6% respectively. The rate of delay in 2-3 domains was lower in boys (41.9%) than in girls (53.1%). The rate of delay in 4-5 domains was higher in boys (58.1%) than in girls (46.9%) ( χ2=352.11, P<0.001). Overall, outpatient GDD decreased with age. From 1.0-1.9 to 4.0-4.9 years of age, the proportion of children with developmental delay in 5 domains increased with age (18.2%, 36.4%, 43.9%, 52.4%). Among children aged 0.0-0.9 years, the proportion of 2 domains of developmental delay was higher (33.4%).Among children aged 1.0-1.9 years, the proportion of 2-3 domains of developmental delay was higher (30.7%). Among children aged 2.0-, 3.0-, 4.0-4.9 years, the proportion of developmental delay in 5 domains was higher (36.4%, 43.9%, 52.4%). In children with GDD, the fine motor delay occurred most frequently (85.1%), followed by social self-care (83.9%), language (79.0%), adaptation (62.3%), and gross motor (52.8%). The frequency of developmental delays in fine motor, adaptability, language, and social self-care in boys was higher than that in girls ( χ2=161.37, χ2=41.10, χ2=320.90, χ2=238.54, all P<0.001). The age groups with the highest delay incidence of gross motor, fine motor, adaptability, language, and social self-care were: 4.0-4.9 years (70.6%), 3.0-3.9 years (97.4%), 4.0-4.9 years (81.2%), 2.0-2.9 years (90.9%),2.0-2.9 years (95.4%). The proportions of fine motor delay in GDD children aged 0.0-0.9, 3.0-3.9 and 4.0-4.9 years were (74.5%, 97.4%, 96.8%) and the proportions of social self-care delay in GDD children aged 1.0- and 2.0-2.9 years were (92.1%, 95.4%). Peripheral and mild developmental delays were predominant in children with GDD. The proportion of severe language delay (6.4%) was higher than that in other fields. Conclusions:The proportion of GDD children with developmental delay in 4-5 domains was 54.5%. The most frequent domain of delay was fine motor. The frequencies of developmental delays in fine motor skills, adaptability, language, and social self-care in boys were higher than in girls. Most of the developmental delays in GDD children were marginal and mild. The rate of severe developmental delay in language was higher than in other domains.

Objective:To investigate repeated dose toxicity of CpG 2395 and summarize common safety characteristics of CpG ODNs.Methods:Rats were randomly divided into 7 groups and injected with different doses of CpG 2395,CpG-Alum adjuvant system and normal saline into hindlimb muscles(4 administrations,2 weeks apart).After administration,clinical observations were conducted at different time points,accompanied by other examinations,such as body weight,food consumption,body temperature,hematology,coagulation,clinical chemistry,urinalysis,cytokines,gross pathology and histopathology.Additionally,repeated dose toxicity results of other CpG ODNs were summarized and analyzed.Results:CpG 2395 possessed relevant attributes to induce significant immunostimu-latory effects,and addition of aluminum adjuvants could enhance these processes.Different CpG ODNs had common safety characteris-tics.Relevant symptoms would be mainly alleviated or eliminated without delayed toxicity after end of administrations,and dose-toxicity relationship had been confirmed.Conclusion:CpG 2395 is considered to be safe and controllable at proposed clinical dose,and based on common safety characteristics,possible local and systemic adverse reactions can be predicted in advance before clinical application of CpG 2395.

OBJECTIVES: This study aims to investigate factors influencing dental arch development in patients aged 0-6 years with cleft palate after Sommerlad-Furlow (SF) palatoplasty. METHODS: A total of 183 patients who underwent primary SF repair for cleft lip and palate before 18 months of age were included. Follow-ups were conducted at different ages, and digital dental casts of the maxillary dental arch were obtained using 3-matic Research 12.0 software. The length and width of the dental arch and palate were measured to explore developmental changes in the maxillary dental arch of the patients after the procedure. The study also investigated the influence of gender, age, cleft palate type, and relaxation incision on maxillary dental arch development. RESULTS: After SF, maxillary dental arch measurements showed statistically significant differences between children aged 0-2 years and those aged 3-6 years (P<0.05). However, no statistically significant differences were observed among different age groups within the 3-6 years range. Statistically significant differences were detected between males and females, with males having greater width of the posterior dental arch and palate (P=0.001) and shorter length of the anterior dental arch and entire dental arch (P<0.05). The unilateral cleft lip and palate group had shorter dental arch length (P<0.01) and wider posterior palate (P<0.01) than the cleft palate only group. Maxillary dental arch measurements had no statistically significant differences between groups with or without a relaxing incision. CONCLUSIONS Gender and age influence the width of the maxillary dental arch in children aged 0-6 years after SF, while age and cleft palate type affect dental arch length.

Objective:To investigate the effect of hypericin (Hyp) on neurologic impairment, ferroptosis and cuproptosis in mice with acute cerebral infarction.Methods:Sixty 8-week old male C57BL/6 mice were randomly divided into sham-operated group, middle cerebral artery occlusion (MCAO) group, MCAO+Hyp low-dose treatment group (L-Hyp group), and MCAO+Hyp high-dose treatment group (H-Hyp group), with 15 mice in each group. Intraluminal filament MCAO models in the later 3 groups were established. Saline was given intraperitoneally into the sham-operated group and MCAO group, and Hyp was given intraperitoneally at 0.5 mg/kg or 1 mg/kg into the L-Hyp group and H-Hyp group 24 hours after modeling. Twenty-four hours after Hyp, neurologic function was assessed using Garcia score, grip strength test, and fatigue baton test; brain tissue edema was assessed by dry-wet weight method; neuronal necrosis, survival and apoptosis were detected by HE staining, Nissl staining and TUNEL, respectively; ferroptosis and oxidative stress were assessed using iron assay kit, and reactive oxygen species (ROS), malondialdehyde (MDA) and glutathione (GSH) assay kits; cuproptosis was assessed using copper assay kit and mitochondrial oxidative phosphorylation was evaluated by mitochondrial respiratory chain complex Ⅲ and Ⅳ activity detection kits; morphological changes in neuronal mitochondria after ferroptosis and cuproptosis were observed by electron microscopy; protein expressions of ferroptosis-associated solute carrier family 7 member 11 (SLC7A11), glutathione peroxidase 4 (GPX4), cuproptosis-associated solute carrier family 31 member 1 (SLC31A1), and ferredoxin 1 (FDX1) were detected by Western blotting.Results:(1) Compared with the MCAO group, the L-Hyp group and H-Hyp group had decreased modified Garcia score and brain water content, increased grip strength and rod-turning time, decreased number of necrotic and apoptotic neurons, increased number of survived neurons, decreased Fe 2+, ROS and MDA levels, increased GSH level and mitochondrial respiratory control rate, and decreased copper content, with significant differences ( P<0.05); and the above changes in the H-Hyp group were more obvious than those in the L-Hyp group, with significant differences ( P<0.05). Compared with the MCAO group, neurons in the L-Hyp group and H-Hyp group had significantly improved status in mitochondrial shrinkage, vacuolation, reduced cristulation, increased membrane density, ruptured cell membrane, endoplasmic reticulum damage and chromatin disruption ( P<0.05); and the H-Hyp group had signficantly more obvious improvement than the L-Hyp group ( P<0.05). (2) Compared with the MCAO group (0.38±0.09, 0.28±0.05), the L-Hyp group and H-Hyp group had significantly increased protein expressions of SLC7A11 and GPX4 (0.83±0.11, 0.49±0.06; 1.27±0.08, 0.84±0.04; P<0.05); the H-Hyp group had significantly higher SLC7A11 and GPX4 expressions than the L-Hyp group ( P<0.05). Compared with the MCAO group (2.76±0.17, 0.67±0.07), the L-Hyp group and H-Hyp group had significantly decreased protein expressions of SLC31A1 and FDX1 (1.72±0.07, 0.51±0.05; 1.12±0.06, 0.34±0.05; P<0.05); the H-Hyp group had significantly lower SLC31A1 and FDX1 expressions than the L-Hyp group ( P<0.05). Conclusion:Hyp can ameliorate ferroptosis and cuproptosis by regulating the protein expressions of SLC7A11, GPX4, SLC31A1 and FDX1, to alleviate oxidative stress injury in MCAO mice, thereby promoting the recovery of neurological function.
