ObjectiveThis paper aims to conduct a secondary analysis of a randomized controlled trial on the treatment of myelodysplastic syndrome （MDS） with deficiency of both the spleen and kidney and blockage of toxin and blood stasis with an arsenic-containing traditional Chinese medicine compound， by applying the mixed model for repeated measure （MMRM） and the method of stratified composite outcome with win ratio. The analysis includes the assessment of hematological efficacy and the composite outcome evaluation of adverse reactions， so as to more comprehensively assess the therapy of this regimen. MethodsThe MMRM and win ratio methods were used to evaluate the efficacy of a prospective，multi-center，double-blind，randomized controlled study. The blood routine （hemoglobin concentration，neutrophil count， and platelet count） and biochemical indexes （aspartate aminotransferase，alanine aminotransferase，serum creatinine，and serum ferritin） of the patients were detected at the time of enrollment and at the end of each course of treatment in the laboratory department of Xiyuan Hospital. The patients' syndromes at the time of enrollment and after treatment were recorded and scored according to the therapy standard of traditional Chinese medicine for diseases and syndromes. MMRM was used to analyze the blood routine indexes of the experimental group and the control group. This method has the advantages of high data reliability and dynamic efficacy under intervention and time. The win ratio method was used to evaluate the composite outcome of traditional Chinese medicine syndrome scores and biochemical indexes according to the priority and to verify the clinical safety of arsenic-containing traditional Chinese medicine compound. ResultsThe results of MMRM analysis showed that the hemoglobin concentration of patients in the group with arsenic-containing traditional Chinese medicine compound increased significantly compared with that before treatment in the group，while that in the placebo group decreased significantly （P<0.01）. When compared with that after treatment in the placebo group，the hemoglobin concentration of patients in the group with arsenic-containing traditional Chinese medicine compound increased significantly，and the mean difference of least squares （LS） was statistically significant （P<0.01）. When compared with those before treatment in the group，there were no statistically significant differences in the neutrophil count and platelet count in both groups. After treatment，there were no statistically significant differences in the neutrophil count， platelet count， and the mean difference of LS between the two groups. The analysis results of win ratio showed that the group with arsenic-containing traditional Chinese medicine compound had a significant advantage in the comparison of composite outcomes，with a win ratio （95% CI） of 2.01 （1.24-3.27） （P<0.01），and that the possibility of "winning" in terms of safety was 2.01 times that of the placebo group. The safety advantage of the group with arsenic-containing traditional Chinese medicine compound mainly came from the traditional Chinese medicine syndrome scores，renal function indexes， and iron reserve capacity indexes，and the number of winning times was less than that of losing times in the comparison of liver function outcomes. ConclusionThe MMRM analysis proves that the arsenic-containing traditional Chinese medicine compound can significantly improve the hemoglobin concentration of patients with myelodysplastic syndrome with refractory cytopenia and multilineage dysplasia （MDS-RCMD） of the type of deficiency of both the spleen and kidney and blockage of toxin and blood stasis. This conclusion is not interfered with by time trends and individual relationships and methodologically improves the credibility of the therapy of the arsenic-containing traditional Chinese medicine compound in treating MDS. Four outcomes are evaluated by the win ratio method，namely traditional Chinese medicine syndromes，liver function，renal function， and iron reserve capacity，proving that the arsenic-containing traditional Chinese medicine compound has the comprehensive advantages of improving the survival quality of the patients and reducing adverse reactions. The win ratio outcome provides clear comparative indexes for the evaluation of adverse reactions，making it easier for regulatory authorities，medical staff， and patients to understand the safety of the arsenic-containing traditional Chinese medicine compound in clinical application.

Protrusive facial deformities, characterized by the forward displacement of the teeth and/or jaws beyond the normal range, affect a considerable portion of the population. The manifestations and morphological mechanisms of protrusive facial deformities are complex and diverse, requiring orthodontists to possess a high level of theoretical knowledge and practical experience in the relevant orthodontic field. To further optimize the correction of protrusive facial deformities, this consensus proposes that the morphological mechanisms and diagnosis of protrusive facial deformities should be analyzed and judged from multiple dimensions and factors to accurately formulate treatment plans. It emphasizes the use of orthodontic strategies, including jaw growth modification, tooth extraction or non-extraction for anterior teeth retraction, and maxillofacial vertical control. These strategies aim to reduce anterior teeth and lip protrusion, increase chin prominence, harmonize nasolabial and chin-lip relationships, and improve the facial profile of patients with protrusive facial deformities. For severe skeletal protrusive facial deformities, orthodontic-orthognathic combined treatment may be suggested. This consensus summarizes the theoretical knowledge and clinical experience of numerous renowned oral experts nationwide, offering reference strategies for the correction of protrusive facial deformities.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.

The objective of this study was to examine the effects of tributyrin(TB)on energy me-tabolism,oxidative stress and immune function in dairy cows with negative energy balance(NEB).In this study,25 perinatal Holstein cows from a dairy farm in Heilongjiang Province were selected.Five healthy cows were designated as the control group,and 20 cows with NEB were randomly di-vided into NEB control group,Propylene glycol(PG)group(300 mL PG),TB group(37.5 g TB)and PG+TB group(300 mL PG+37.5 g TB)with 5 cows in each group,and were continuously fed for 14 days.Blood samples were collected at 0,7,14 and 21 days.The indexes of oxidative stress,energy metabolism and immune function in the serum of dairy cows were quantified using commercially available kits.The results showed that compared with the NEB group,the contents of T-AOC,GSH-Px,CAT and SOD in the TB group were significantly increased,whereas the content of MDA was significantly decreased.These results indicated that TB can effectively alleviate the oxidative stress of cows with NEB.The contents of BHB,NEFA and BUN in the TB group were significantly decreased,indicating that TB can regulate energy metabolism disorders in cows with NEB.The contents of IL1β,IL-2,IL-6,IL-21,MIP-1 and IP-10 in the TB group were significantly decreased,while the contents of IgA,IgM and IgG were significantly increased.These results sug-gest that TB has shown significant effects in inhibiting inflammatory response and improving im-mune function.Furthermore,compared with the PG group,the contents of T-AOC,GSH-Px,CAT,SOD,IgA,IgM and IgG in the TB group and the PG+TB group were significantly in-creased,whereas the contents of MDA,BHB,NEFA,BUN,IL-1β,IL-2,IL-6,IL-21,MIP-1 and IP-10 were significantly decreased.These results indicated that feeding TB alone was effective in alle-viating oxidative stress,improving energy metabolism and inhibiting inflammation in dairy cows compared to feeding the traditional drug PG,and the effect of feeding a mixture of PG and TB was particularly significant.This study provides a new theoretical basis for the prevention and treat-ment of oxidative stress and immune function decline caused by perinatal cows with NEB.

The aim of this study is to investigate whether β-hydroxybutyrate(BHB)impaired the mitochondrial function of dairy cow monocytes through the peroxisome proliferator-activated re-ceptor γ coactivator 1 alpha(PGC-1α)signaling pathway.According to the clinical symptoms and the concentration of BHB in whole blood,the tail vein blood of 12 healthy cows(BHB＜1.2 mmol/L)and 12 clinical ketotic cows(CK,BHB＞3.0 mmol/L)was collected.In vivo,after isolation and purification of CD14+monocytes,the intracellular mitochondrial membrane potential was detected by flow cytometry.The protein abundance of oxidative phosphorylation complex cytochrome c oxi-dase subunit Ⅰ(CO Ⅰ),CO Ⅱ,CO Ⅲ,COⅣ,CO Ⅴ,PGC-1 α,mitochondrial transcription factor A(TFAM)and nuclear respiratory factor 1(NFR1)were determined by Western blot.In vitro,CD14+monocytes were co-cultured with 3.0 mmol/L BHB for 0,6,12,24 h.Flow cytometry was applied for intracellular mitochondrial membrane potential detection,and determination the protein abundance of PGC-1α,TFAM and NFR1 by Western blot.The results showed that compared with control group,the mitochondrial membrane potential in CD14+monocytes of ketotic cows was sig-nificantly increased,and the protein abundance of CO Ⅰ,CO Ⅱ,CO Ⅲ,CO Ⅳ,CO Ⅴ PGC-1α,TFAM,and NRF1 in CD14+monocytes of ketotic cows were significantly decreased.Compared with 0 h,the mitochondrial membrane potential of CD14+monocytes was significantly increased after BHB treatment for 6,12,24 h,and the protein abundance of PGC-1α,TFAM and NRF1 were significantly decreased.The results indicated that BHB induced mitochondrial dysfunction in CD14+monocytes of ketotic cows by inhibiting PGC-1α signaling pathway.Therefore,the PGC-1αsignaling pathway may be a preventive and therapeutic target to the mitochondrial dysfunction of monocytes in ketotic cows caused by BHB.

Human amnion (hAM), as a biomaterial, has made significant progress in the field of ophthalmology, particularly in the treatment of retinal diseases. hAM possesses biological properties such as promoting tissue repair, inhibiting inflammation and neovascularization, and reducing fibrosis, which have led to its promising clinical outcomes in treating macular holes, retinal detachment, proliferative vitreoretinopathy, optic disc depression-related macular detachment, and age-related macular degeneration. The application of hAM can improve surgical success rates and promote vision recovery, with no significant rejection reactions observed due to its low immunogenicity. Nevertheless, the use of hAM still faces challenges in optimizing preparation and storage techniques, enhancing therapeutic efficacy, and reducing the risk of infectious disease transmission. Future research should focus on addressing these issues to further promote the application of hAM in retinal disease treatment and enhance its effectiveness.
