Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

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.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Background: Genetic defects in the human thyroid-stimulating hormone (TSH) receptor (TSHR) gene can cause congenital hypothyroidism (CH). However, the biological functions and comprehensive genotype–phenotype relationships for most TSHR variants associated with CH remain unexplored. We aimed to identify TSHR variants in Chinese patients with CH, analyze the functions of the variants, and explore the relationships between TSHR genotypes and clinical phenotypes. Methods: In total, 367 patients with CH were recruited for TSHR variant screening using whole-exome sequencing. The effects of the variants were evaluated by in-silico programs such as SIFT and polyphen2. Furthermore, these variants were transfected into 293T cells to detect their Gs/cyclic AMP and Gq/11 signaling activity. Results: Among the 367 patients with CH, 17 TSHR variants, including three novel variants, were identified in 45 patients, and 18 patients carried biallelic TSHR variants. In vitro experiments showed that 10 variants were associated with Gs/cyclic AMP and Gq/11 signaling pathway impairment to varying degrees. Patients with TSHR biallelic variants had lower serum TSH levels and higher free triiodothyronine and thyroxine levels at diagnosis than those with DUOX2 biallelic variants. Conclusions We found a high frequency of TSHR variants in Chinese patients with CH (12.3%), and 4.9% of cases were caused by TSHR biallelic variants. Ten variants were identified as loss-of-function variants. The data suggest that the clinical phenotype of CH patients caused by TSHR biallelic variants is relatively mild. Our study expands the TSHR variant spectrum and provides further evidence for the elucidation of the genetic etiology of CH.

BACKGROUND:Recent studies have shown that the occurrence and prevention of osteoporosis often focus on the cellular molecular level,and the mechanism of related signaling pathways is an important way to further understand osteoporosis.At present,traditional Chinese medicine has been proved to play a significant role in alleviating osteoporosis.Kaempferol as an emerging Chinese herbal extract has become the focus of clinical and basic research due to its anti-osteoporosis effectiveness and mechanism of action. OBJECTIVE:To further understand the mechanism underlying the anti-osteoporosis effect of kaempferol active monomer through regulation of related signaling pathways by analyzing and collating domestic and foreign literature. METHODS:"Kaempferol,osteoporosis,osteoblasts,osteoclasts,bone marrow mesenchymal stem cells,signaling pathways"were used as Chinese and English search terms to search CNKI,WanFang,VIP,PubMed,Web of Science and Embase databases for relevant literature published from database inception to February 2023. RESULTS AND CONCLUSION:Kaempferol affects the occurrence and progression of osteoporosis to varying degrees by participating in the regulation of differentiation,proliferation and apoptosis of bone marrow mesenchymal stem cells,osteoblasts and osteoclasts.Kaempferol can prevent and treat osteoporosis by regulating various signaling pathways.Kaempferol can promote the proliferation and differentiation of osteoblasts and inhibit the formation of osteoclasts by interfering with the Wnt/β-catenin signaling pathway to regulate β-catenin protein counting and the formation of β-catenin-TCf/LEF complex.Kaempferol interferes with the RANK/RANKL pathway to maintain the dynamic balance of osteoclasts and bone homeostasis.Kaempferol can promote bone formation by intervening with the PI3K/Akt signaling pathway to upregulate the levels of related osteogenic factors Runx2 and Osterix and promote bone cell calcification.Kaempferol interferes with osteoclast differentiation and inhibits reactive oxygen species activity by regulating the ER/ERK pathway.Kaempferol inhibits the expression of ERK,JNK,p38/MAPK and decreases reactive oxygen species production by interfering with the MAPK pathway,thus protecting osteogenesis.Kaempferol enhances the expression of osteogenic factors,bone morphogenetic protein-2,p-Smad1/5/8,β-catenin and Runx2,inhibits the expression of Peroxisome proliferation-activated receptor,and promotes the differentiation and proliferation of osteoblasts through the BMP/Smad pathway.

Objective To compare the results of accumulation and continuation methods in indoor radon measurement. Methods The radon concentrations in 30 households in 7 provincial capital cities of China were simultaneously measured using both accumulation and continuation methods. Results The radon concentration measured by accumulation method in 30 households ranged from 21 to 323 Bq/m³, with a median M(P₂₅, P₇₅) of 70.5 (43.8, 111). The radon concentration measured by the continuation method ranged from 16.1 to 258 Bq/m³, with a median M(P₂₅, P₇₅) of 100 (51.3, 141). The average relative percent deviation between the two measurement methods was 41.8%. There were significant differences among the measurement results at 8, 16, and 24 h by the continuation method. Pairwise comparisons showed there were statistical diffferences between 8 h and 16 h, as well as between 8 h and 24h; however, no statistical significance was found (P < 0.05), between 16 h and 24 h. Conclusion The overall continuous measurement results of the 30 households were higher than those of cumulation method. The comparison between accumulation and continuation measurement results did not show a high level of correlation (r=0.49). The continuation method is significantly affected by environmental factors, and the length of the measurement period can affect the measurement results. The selection of indoor radon measurement methods should consider the purpose, sample size, and environmental conditions.

Objective:To investigate the effects of Houttuynize Herba decoction on aspirin-induced gastric ulcer (GU) in mice; To discuss its mechanism.Methods:A total of 64 SPF male mice were selected, and 48 mice were randomly selected to establish the model by gavage of 20 mg/ml aspirin solution. The remaining 16 rats were treated as normal group by gavage with the same amount of normalsaline once a day for 7 consecutive days. After successful modeling, the remaining mice in the model group were randomly divided into 5 groups, with 8 mice in each group, namely normal saline group (given normal saline), omeprazole group (given omeprazole 0.5 mg/ml), Houttuynize Herba high-, medium- and low-dosage groups (given 1.08 g/ml, 0.54 g/ml, 0.27 g/ml), and the remaining 8 mice in the normal group were given the same amount of normal saline by gavage. The mice were treated by gavage once a day for 7 days. The number of Escherichia coli and Bifidobacterium in mouse feces was counted by bacterial culture method, and the ratio of Bifidobacterium to Escherichia coli (B/E value) was used to judge the imbalance of bacterial flora. The expression of interleukin-6 (IL-6) in serum was detected by magnetic particle chemiluminescence. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of prostaglandin E 2 (PGE 2) in the serum of mice to determine the level of inflammation. Hematoxylin-eosin staining was used to determine the ulcer and healing. ImageJ 1.8.0 was used to calculate the ulcer inhibition rate. The protein expression levels of IκBα, NF-κB-p65 subunit and phosphorylated IκBα (p-IκBα) and p65 (p-NF-κB-p65) subunits in gastric tissue of mice were evaluated by Western blot. Results:Compared with the normal group, the epithelial cells of the gastric mucosa were missing, the glands were irregularly arranged, and the tissue structure was severely damaged in the modeling group; the number of Escherichia coli in the intestine increased ( P<0.01), the number of Bifidobacterium decreased ( P<0.01), and the B/E value was less than 1 ( P<0.01); Serum PGE2 levels were decreased ( P<0.01), IL-6 levels were increased ( P<0.01); The expression of p-IκBα and p-NF-κB-p65 proteins in gastric tissues was elevated ( P<0.05). After 7 days of drug treatment, compared with the saline group, gastric mucosal cells and structures were improved, and weight gained in the Houttuynize Herba groups ( P<0.05); the rate of inhibition of ulcers in mice in the Houttuynize Herba high-dosage group was significantly improved ( P<0.01); the number of Bifidobacteria in the intestinal tract significantly increased ( P<0.01), that of Escherichia coli was diminished ( P<0.05), B/E value was greater than 1 ( P<0.05), IL-6 content in peripheral blood was reduced ( P<0.05), PGE 2 levels significantly increased ( P<0.01); the level of p-IκBα/IκBα and p-NF-κB-p65/NF-κB-p65 in the gastric tissues of mice decreased ( P<0.01). Conclusion:Houttuynize Herba decoction can effectively improve gastric mucosal injury in mice, and its mechanism may be related to regulating intestinal microorganisms, inhibiting the opening of IκBα/NF-κB pathway, and reducing inflammatory response.

Objective To investigate the effect of nobiletin on platelet-activating factor(PAF)metabolism in diabetic rats with renal injury.Methods Totally 72 rats were randomly divided into control group(n=10)and modeling group(n=62).The modeling group rats were induced to develop a diabetic rat model with renal injury and then further divided into the model group,aspirin group(20 mg/kg),and nobiletin low(50 mg/kg),medium(100 mg/kg),and high-dose(200 mg/kg)groups,each with 10 rats.After continuous oral administration for 6 weeks,rat body weight,kidney weight,and kidney index were measured.Histopathological assessments were conducted by using HE,periodic acid-Schiff staining(PAS),Masson staining,and transmission electron microscopy.Blood glucose levels,renal function,inflammatory factors,PAF and its regulatory factors were detected.Expression levels of PAF metabolism-related proteins,PAF-acetylhydrolase(PAFAH),PAF receptor(PAFR),and cholinephosphotransferase 1(CHPT1)in kidney tissues were assessed using Western blotting and immunohistochemistry.Results Following nobiletin intervention,rat body weight increased while kidney weight and kidney index decreased.Improvement in renal tissue pathology was observed,with reduced interstitial fibrosis and thinner basement membrane.Fasting blood glucose and glycated hemoglobin decreased,while fasting insulin showed no significant improvement.Urea nitrogen,blood creatinine,cystatin C,and 24-hour urinary protein excretion were reduced.Levels of interleukin(IL)-1α,IL-6,IL-8,and tumor necrosis factor(TNF-α)were lowered.PAF and its regulatory factors decreased.PAFR and CHPT1 expression decreased,while PAFAH increased.Conclusion Nobiletin can alleviate renal injury in diabetic rats with renal injury,improve kidney function,regulate blood glucose,and mitigate inflammatory response.Its mechanism may be associated with the modulation of platelet-activating factor metabolism.
