BACKGROUND:Osteoblasts are the main cell types responsible for bone formation and remodeling,and the normal performance of their function is precisely regulated by various signaling pathways.Among them,the bone morphogenetic protein and Wnt signaling pathways play a key role in osteogenesis. OBJECTIVE:To review the role of bone morphogenetic protein/Wnt signaling pathway in the regulation of osteoblast function and analyze its changes in different physiological and pathological conditions in order to further reveal the molecular mechanism of bone formation and remodeling. METHODS:The Chinese and English search terms"BMP signaling pathway,Wnt signaling pathway,and osteogenesis"were searched in CNKI,Wanfang,and PubMed databases for original researches published from the inception to June 2023.Totally 61 articles were finally selected for analysis and summary.Using the method of the literature review,the studies of the bone morphogenetic protein/Wnt signaling pathway in regulating osteogenesis were sorted out and analyzed. RESULTS AND CONCLUSION:(1)Bone morphogenetic protein and Wnt signaling pathways play important roles in the differentiation,proliferation,and maturation of osteoblasts.Bone morphogenetic protein signaling pathway mainly regulates the expression of osteogenesis-related genes through the activation of Smad protein.Smad protein enters the nucleus and regulates the expression of genes related to osteogenesis.Different Wnt signaling pathway from bone morphogenetic protein mainly depends on the activation of β-catenin to exert its biological effects.(2)The regulatory effect of bone morphogenetic protein/Wnt signaling pathway will be affected by many factors in different physiological and pathological states.Growth factors,hormones,and mechanical stress can affect the activity of bone morphogenetic protein/Wnt signaling pathway to some extent.(3)Bone morphogenetic protein/Wnt signaling pathway interacts with other signaling pathways in the regulation of osteogenesis,and they together constitute a complex regulatory network.(4)Chinese medicine and natural compounds can promote bone health by regulating signaling pathways,providing new possibilities for treating bone diseases.(5)Future studies can further explore the interaction of bone morphogenetic protein/Wnt signaling pathway and other signaling pathways and its changes in different physiological and pathological conditions,resolve the key nodes and regulation mechanism in the complex network,to provide more precise targets for the treatment of bone-related diseases,and also provide new ideas to reveal the molecular mechanism of bone formation and remodeling.

OBJECTIVE:The optimal non-surgical therapy for chronic ankle instability remains unclear due to the continuous introduction of novel treatment methods despite the availability of several non-surgical options for improving foot and ankle function and dynamic balance in chronic ankle instability patients.This study aims to investigate the most effective non-surgical therapy options to improve foot and ankle function and dynamic balance for patients with chronic ankle instability using a network meta-analysis. METHODS:Using"CAI,exercise,and randomized controlled trial"as search terms,a literature search of PubMed,Embase,Cochrane Library,and Web of Science databases was conducted through a computer network to collect information from the databases from their inception to March 2024 on non-surgical therapies for the treatment of chronic ankle instability randomized controlled trials on foot and ankle function or dynamic balance in patients.EndNote software was utilized for literature management.RevMan 5.4 software and Cochrane Risk of Bias Assessment Tool were used to evaluate the risk of bias of the included literature.Paired meta-analysis and network meta-analysis of the outcomes such as the Foot and Ankle Ability Measure in daily living subscale score,Foot and Ankle Ability Measure in sports activities subscale score,Star Excursion Balance Test-Anterior score,Star Excursion Balance Test-Posteromedial score,Star Excursion Balance Test-Posterolateral score and Cumberland ankle instability tool score were performed using the network commands of Stata 14.0 software.The strength of evidence rating of the outcome metrics was evaluated according to the GRADE Level of Evidence and Strength of Recommendation Grading Criteria. RESULTS:Of the 22 randomized controlled trials that met the inclusion criteria,1 study was rated as low risk,8 studies were rated as medium risk,and 13 studies were rated as high risk,enrolling a total of 952 patients and 25 treatments.(1)Network meta-analysis showed that compared with the control group,Isokinetic Strength Training,Balance Training,Balance+Stroboscopic Glasses Training,Strength Training,Joint Mobilizations Training,CrossFit Training,CrossFit Training+Self-Mobilization,Wobble Board Training,National Academy of Sport Medicine corrective exercise program,Trigger Point Dry Needling,and Neuromuscular Training had different significant enhancement effects on improving foot and ankle function and dynamic balance in patients with chronic ankle instability(P<0.05).(2)Cumulative probability ranking results showed that the three treatments with the highest ranked Cumberland ankle instability tool score were Joint Mobilizations Training(88.6%)>Visual Feedback Balance Training(83.1%)>CrossFit Training+Self-Mobilization(74.8%);the three treatments with the highest ranked Star Excursion Balance Test-Anterior score were Joint Mobilizations Training(88.4%)>Isokinetic Strength Training(86.9%)>National Academy of Sport Medicine corrective exercise program(65.0%);the three treatments with the highest ranked Star Excursion Balance Test-Posteromedial score were Balance+Stroboscopic Glasses Training(87.4%)>Neuromuscular Training(74.6%)>Strength Training(68.9%);the three treatments with the highest ranked Star Excursion Balance Test-Posterolateral score were CrossFit Training+Self-Mobilization(74.6%)>Balance+Stroboscopic Glasses Training(70.0%)>Neuromuscular Training(63.7%);the three treatments with the highest ranked Foot and Ankle Ability Measure in daily living subscale score were National Academy of Sport Medicine corrective exercise program(91.9%)>Balance+Stroboscopic Glasses Training(85.6%)>Wobble Board Training(82.2%);the three treatments with the highest ranked Foot and Ankle Ability Measure in sports activities subscale score were Balance+Stroboscopic Glasses Training(93.5%)>Balance Training(86.7%)>National Academy of Sport Medicine corrective exercise program(86.4%). CONCLUSION:Non-surgical therapies can significantly improve foot and ankle function and dynamic balance in patients with chronic ankle instability.National Academy of Sport Medicine corrective exercise program had the best efficacy in improving foot and ankle daily activity function in chronic ankle instability patients;Balance+Stroboscopic Glasses Training had the best efficacy in improving foot and ankle sports function and posterior medial dynamic balance;Joint Mobilizations Training had the best efficacy in improving anterolateral dynamic balance and ankle instability condition;and CrossFit Training+Self-Mobilization had the best efficacy in improving posterior lateral dynamic balance.The strength of evidence for each outcome was low,influenced by the risk of methodological bias and risk of publication bias of the included studies.Therefore,the above conclusions need to be validated by more high-quality pilot studies.

Goiter is a kind of non-inflammatory and non-neoplastic hyperplasia and enlargement. Many studies have shown that substances such as thiocyanates and isothiocyanates can prevent the development of a variety of tumors. However, some studies have also found that such substances can lead to goiter. In this article, relevant information on common goitrogen in food are collected to explore their mechanism of action, laying a foundation for guiding residents to maintain a healthy and balanced diet.

Objective:To assess the long-term outcome of sequential radical surgery after immune combined with targeted therapy for patients with initially unresectable hepatocellular carcinoma (HCC).Methods:Clinical data of 100 patients with initially unresectable HCC undergoing sequential radical surgery after immune combined with targeted therapy at the Faculty of Hepato-Pancreato-Biliary Surgery of Chinese PLA General Hospital from December 2018 to August 2023 were prospectively collected, including 87 males and 13 females, with a median age of 55 (24-73) years. The pre-treatment tumor staging was determined using the China liver cancer staging (CNLC). The efficacy of immune combined with targeted therapy was accessed using the modified response evaluation criteria in solid tumor (mRECIST). The cycles of immune combined with targeted therapy were analyzed. The tumor residual of resected tissue was analyzed through a standard pathological protocol. The prognosis was analyzed using the Kaplan-Meier method.Results:Upon initial diagnosis, there were 46 cases (46.0%) staged CNLC-Ⅲa and 40 (40.0%) staged CNLC-Ⅲb. There were also 14 cases (14.0%) staged CNLC-Ⅰb, Ⅱa, and Ⅱb who underwent immune combined with targeted therapy due to rupture of tumor or insufficient liver remnant. All patients received a median of 5 (3-28) cycles of immune combined with targeted therapy and underwent radical surgery after successful conversion. According to mRECIST, 14 (14.0%) were determined as complete remission, 63 (63.0%) as partial remission, 18 (18.0%) as stable disease, and 5 (5.0%) as disease progression. Of 24 (24.0%) were defined as pathologically complete remission by postoperative pathology. Furthermore, pathological tumor residue was less than 10% in 61 (61.0%) cases and less than 50% in 82 (82.0%) cases. The 1, 3, and 5 year-overall survival rates of patients were 98.0%, 83.1%, and 74.5%, respectively. The 1, 2 and 3 year-recurrence-free survival rates were 67.5%, 54.8%, and 49.6%, respectively.Conclusion:Sequential radical surgery after immune combined with targeted therapy benefits the long-term survival of patients with initially unresectable HCC.

Herb-induced liver injury(HILI)tends to have complex toxic material basis and toxic mechanism,which greatly affects the safety of traditional Chinese medicine.This article summarizes the main toxic components of Chinese herbal medicine causing liver injury and their mechanism of action.The toxic components of Chinese herbal medicine causing liver injury can be classified into two categories of drug-derived and non-drug-derived toxic components.Drug-derived toxic components mainly include alkaloids,terpenoids,anthraquinones,and phenylpropanoids,and their mechanism of action involves oxidative stress,apoptosis and necrosis,CYP450 enzymes,and genotoxicity.Non-drug-derived toxic components mainly include pesticide residues,sulfur dioxide residues,heavy metals,fungi,and plant growth regulators,and their mechanisms involve oxidative stress,apoptosis,metabolic disorders,and CYP450 enzymes.On this basis,this article further proposes the unsolved problems and research difficulties,in order to promote the basic research on the hepatotoxicity of traditional Chinese medicine.

Objective:To study the diagnostic value of artificial intelligence B-ultrasound image computer-aided diagnosis system (hereinafter referred to as intelligent ultrasound system) in adult goiter.Methods:In June 2022 and March 2023, two phases of thyroid disease survey were carried out in 4 cities in Anhui Province. One village was selected in each city, and 250 adults were selected as survey subjects in each village. Adult bilateral thyroid area was scanned by both intelligent ultrasound system and conventional ultrasound scanning equipment, and the effectiveness of intelligent ultrasound system in the diagnosis of goiter was analyzed based on the results of conventional ultrasound examination. Receiver operating characteristic (ROC) curve was drawn, and Kappa test was used to analyze the consistency between intelligent ultrasound system and conventional ultrasound examination in the diagnosis of goiter. At the same time, Spearman correlation analysis and Bland-Altman method were used to evaluate the consistency of the two methods in measuring thyroid volume.Results:After screening and removing outliers and missing values, a total of 910 adults were included, including 253 males (27.80%) and 657 females (72.20%). The age was (45.92 ± 10.20) years old, ranging from 18 to 60 years old. The sensitivity, specificity, and accuracy of the intelligent ultrasound system for diagnosing adult goiter were 80.00%, 99.67%, and 99.56%, respectively. The area under the ROC curve (AUC) was 0.996, which was consistent with the results of conventional ultrasound examination for diagnosing goiter ( κ = 0.67, P < 0.001). After controlling for variables such as gender, thyroid function, and thyroid nodules, the intelligent ultrasound system showed good consistency with conventional ultrasound examination in the diagnosis of goiter in females, adults with thyroid dysfunction, and adults without thyroid nodules ( κ = 0.66, 0.80, 0.80, P < 0.001). The consistency in the diagnosis of goiter in adults with thyroid nodules was moderate ( κ = 0.56, P < 0.001). Spearman correlation analysis showed a highly positive correlation between the measurement results of adult thyroid volume by intelligent ultrasound system and conventional ultrasound examination ( r = 0.88, P < 0.001). The Bland-Altman method results showed that only 4.62% (42/910) of points in adults were outside the 95% consistency limit, indicating good consistency between intelligent ultrasound system and conventional ultrasound examination in measuring thyroid volume (< 5%). The proportion of points outside the 95% consistency limit in males, adults with thyroid dysfunction, and adults with thyroid nodules was 6.72% (17/253), 5.83% (12/206), and 6.45% (12/186), respectively. Conclusions:The intelligent ultrasound system has certain diagnostic value for adult goiter and has good consistency with conventional ultrasound examination for thyroid volume measurement. However, the accuracy of diagnosis for males and adults with thyroid nodules still needs to be improved.

Objective:To evaluate the necessity, safety and efficacy of endovascular treatment for cerebral infarction caused by middle cerebral artery (MCA) stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery.Methods:The clinical and surgical data of patients with MCA atherosclerotic disease who underwent endovascular treatment in the First Affiliated Hospital of Zhengzhou University from January 2014 to October 2021 were retrospectively analyzed. A total of 6 patients with cerebral infarction caused by MCA stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery were selected. The preoperative and postoperative clinical imaging characteristics, perioperative complications and follow-up of these 6 patients were summarized and evaluated.Results:After the endovascular treatment, the imaging of the lenticulostriate artery in all the 6 patients was clearer than that before the operation, and the number of main trunks of the lenticulostriate artery shown by imaging in 2 patients was more than that before operation. The computer tomography perfusion of 6 patients after the endovascular treatment showed that perfusion in the supply area of the lenticulostriate artery was significantly improved compared with pre-operation. No stroke, transient ischemic attack (TIA) and death occurred during the perioperative period. The time of clinical follow-up was 360 (322, 495) days, and there were no stroke, TIA or death occurring in the corresponding artery. All the 6 patients underwent imaging follow-up, of which 3 patients underwent digital subtraction angiography and 3 underwent CT angiography. The lumen of the target vessels showed patency in all patients.Conclusions:With rigorous imaging evaluation, endovascular treatment may be safe and effective for cerebral infarction caused by MCA stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery.

Objective:To assess the clinical efficacy of sequential radical surgery after immune and targeted therapy in downstaging patients with initially unresectable hepatocellular carcinoma.Methods:Data were prospectively collected from December 2018 to July 2022 on patients with initially unresectable hepatocellular carcinoma which were downstaged to undergo sequential surgery after treatment with immune and targeted therapy at the Faculty of Hepato-Pancreato-Biliary Surgery, Chinese PLA General Hospital. There were 79 patients, with 69 men and 10 women, aged (53.0±10.9) years, being enrolled into this study. The Kaplan-Meier method was used to calculate the survival rate, and the log-rank test was used for survival rate comparison. Univariate and multivariate Cox regression were used to analyze factors influencing patient prognosis.Results:There were 7 patients (8.9%) with China Liver Cancer Staging (CNLC) Ⅰb, Ⅱa, Ⅱb who had insufficient residual liver volume or tumor rupture before the downstaging therapy, and 38 patients (48.1%) with CNLC Ⅲa and 34 patients (43.0%) with CNLC Ⅲb. These 79 patients underwent R 0 resection after 3-20 cycles (median 5 cycles) of immune and targeted therapy. Based on the modified response evaluation criteria in solid tumor, the results of preoperative imaging assessment were: complete remission in 12 patients (15.2%), partial remission in 50 patients (63.3%), stable disease in 15 patients (19.0%), and disease progression in 2 patients (2.5%). The overall survival rates of patients at 1, 2, and 3 years after diagnosis were 96.1%, 83.5%, and 76.6%; and the recurrence-free survival rates at 1, 2, and 3 years after surgery were 62.1%, 52.9%, and 34.7%, respectively. On multivariate Cox regression analysis, patients with a preoperative alpha-fetoprotein >20 μg/L ( HR=2.816, 95% CI: 1.232-6.432, P=0.014) and a high proportion of pathological residual tumors ( HR=1.015, 95% CI: 1.004-1.026, P=0.006) had a higher risk of postoperative recurrence; and patients with a high proportion of pathological residual tumors ( HR=1.028, 95% CI: 1.007-1.049, P=0.007) and preoperative alpha-fetoprotein >400 μg/L ( HR=4.099, 95% CI: 1.193-14.076, P=0.025) had a higher risk of death. Conclusion:Immunotherapy combined with targeted therapy and sequential surgery for patients with initially unresectable hepatocellular carcinoma provided long-term survival benefits. Elevated preoperative alpha-fetoprotein and a high proportion of pathological residual tumor were independent risk factors for recurrence-free survival and overall survival in this group of patients.
