Bronchial asthma （BA） is a common chronic inflammatory airway disease characterized by airway hyperresponsiveness and reversible airflow limitation. Lung macrophages （LMs）， as important effector cells of the innate immune system， play an important role in recognizing and engulfing pathogens， clearing harmful particles， and regulating immune responses. LMs can be polarized to M1 （pro-inflammatory） or M2 （anti-inflammatory） in different immune environments and participate in promoting or inhibiting inflammatory response， as well as lung parenchyma injury and repair （airway remodeling）， playing a key role in the BA occurrence and development. Regulating the polarization balance of macrophages can not only inhibit the inflammatory response in the airway and reduce airway hyperresponsiveness， but also improve airway remodeling and immune regulation， reduce airway mucus secretion， and alleviate the clinical BA symptoms. Traditional Chinese medicine and its active ingredients， especially polysaccharides and saponins， can regulate the polarization balance of M1/M2 macrophages. Traditional Chinese medicine compounds can balance the secretion of anti-inflammatory and pro-inflammatory factors by staging treatment and targeting the polarization state of M1/M2 macrophages， inhibit inflammatory response in the airway， reduce airway remodeling， and improve the BA symptoms. This paper summarized the research progress on the regulation of M1/M2 macrophage polarization by traditional Chinese medicine and its active ingredients， aiming to provide scientific evidence for the precise targeted therapy of BA.

Dry eye disease is a multifactorial chronic ocular surface disorder that is challenging to manage because its pathogenesis is not well understood. The gut-eye axis theory provides insights into its pathogenesis to guide prevention and treatment. Intestinal flora dysbiosis induces dry eye disease through complex mechanisms involving inflammation, ocular surface microbiota, nerve damage, and microbial metabolites. This article reviews the immunometabolic regulation of the gut-eye axis and summarizes gut flora-targeted interventions(fecal microbiota transplantation, probiotic supplementation, and dietary modification)to provide a theoretical basis for dry eye disease prevention and treatment.

Objective: To understand current state of physical health levels of first year students in different body mass index (BMI) categories in Ningxia universities, and to explore the correlation between BMI and physical fitness index (PFI), so as to provide a reference for enhancing physical health levels of university students. Methods: In November 2024, physical fitness test data from 16 631 first year students across four universities in Yinchuan City, Ningxia from 2019 to 2023 were collected by adopting convenience and stratified cluster random sampling methods. The PFI was calculated using the Z score of the physical fitness test results, and a nonlinear quadratic model was established via least squares regression to examine the relationship between BMI and PFI among university students. Results: The BMI for males was (21.69±3.53)kg/m 2, while for females was (20.78±2.94)kg/m 2. The composite score for males physical fitness (69.86±9.25) was lower than that for females (72.24± 8.15 ), with a statistically significant difference ( t =-17.54, P <0.01). Moreover, the failure rates of various physical fitness indicators (vital capacity, sit and reach, standing long jump, pull ups/1 minute sit ups, 1 000 m/800 m run) were higher among males than females ( χ 2=103.48, 72.45, 14.38, 5 134.85, 188.89, all P <0.01). Comparisons across BMI categories revealed that among males, the normal weight group outperformed other groups in the 50 m sprint, standing long jump, 1 000 m sprint, composite score, and PFI ( F =89.17, 113.90, 179.02, 573.35, 593.08); among female students, the normal weight group outperformed other groups in the 50 m sprint, sit and reach, 800 m run, composite score, and PFI ( F =10.67, 19.58 , 96.45, 294.05, 183.45) (all P <0.01). The relationship between BMI and PFI among first year students exhibited a parabolic change trend, students with a moderate BMI demonstrated higher PFI, and as BMI increased, PFI decreased (all P <0.01). Conclusions The physical health level of male students in Ningxia universities is lower than that of female students. There is a correlation between BMI classification and PFI. Tailored intervention measures should be implemented according to the physical characteristics of students across different genders and BMI classifications to enhance university students physical health.

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 To explore the impact of an intelligent puncture navigation used by different physicians with varying years of experience to perform the lung puncture biopsy surgery.Methods A retrospective selection was conducted of 182 patients who completed lung puncture biopsy surgery.The primary parameters were recorded included puncture time,the number of needle adjust-ments,dose length product(DLP),and complications.The physicians were categorized into high-experience and low-experience groups based on their years of clinical practice.The differences of navigation guidance and manual puncture were compared between the two groups.Results The use of navigation guidance significantly reduced the procedure time for both groups of physicians(P<0.05).Additionally,for the low-experience group,navigation guidance notably decreased the number of needle adjustments(P<0.05)and reduced the radiation dose received by patients(P<0.05).Conclusion The application of intelligent puncture navigation can shorten the procedure time,reduce the number of needle adjustments,and lower the radiation dose received by patients in lung puncture biopsy procedures.It also bridges the operational performance gap between low-experience and high-experience physicians,making it a val-uable imaging-guided tool for widespread adoption.

Objective To observe the clinical efficacy of therapy focusing on regulating spleen and stomach for the treatment of acoustic hypersensitivity(AH),which also named as auditory hyperaesthesia,and to explore the relevant factors influencing the efficacy.Methods From January 2018 to December 2023,the patients admitted to the outpatient department of otolaryngology-head and neck surgery of the First Affiliated Hospital of Guangzhou University of Chinese Medicine and diagnosed as AH with complete medical data were included as study subjects.Follow-up through telephone or network was carried out for those patients who with uncertain prognosis.The changes in the pre-and post-treatment scores of Indicators of Acoustic Hypersensitivity Severity(IAHS)were used as the reference index for efficacy evaluation,and the cure rate and effective rate were used as the efficacy analysis indexes for statistical analysis.And then the efficacy of traditional Chinese medicine(TCM)medical care combined with health care focusing on regulating spleen and stomach for the treatment of AH was evaluated.Furthermore,multivariate logistic regression was used to explore the relevant factors influencing the efficacy of AH.Results A total of 298 cases of AH patients meeting the inclusion criteria were collected,among which 151 cases(50.67%)were cured,22 cases(7.38%)were markedly effective,75 cases(25.17%)were effective,and 50 cases(16.78%)were ineffective,with a total effective rate of 83.22%(248/298).The univariate analysis results showed that eight factors(including post-treatment lifestyle score,range of lifestyle adjustment,severity of AH,duration of the disease,presence of tinnitus,presence of hearing drop,presence of vertigo,and age)had an influence on the efficacy,and the differences were statistically significant(P<0.05 or P<0.01).However,the factors of gender,occupation,education level,and history of noise exposure had no influence on the efficacy(P>0.05).The multivariate binary logistic regression analysis showed that five factors,namely post-treatment lifestyle score,range of lifestyle adjustment,severity of AH,presence of vertigo and duration of the disease,had a significant correlation with the cure rate of AH(P<0.05 or P<0.01),and four factors,namely post-treatment lifestyle score,severity of AH,range of lifestyle adjustment and age,had a significant correlation with the effective rate of AH(P<0.05 or P<0.01).Conclusion The method of TCM medical care and health care focusing on regulating spleen and stomach exerts a better efficacy for AH patients.And the lifestyle,severity of AH,duration of the disease,age,and presence of vertigo are the relevant factors affecting the outcomes,which is worthy of further in-depth study.

Objective:To investigate the safety and feasibility of the domestic single-port serpentine-arm robotic surgical system for pyeloplasty in children with congenital ureteropelvic junction obstruction(UPJO).Methods:Data of UPJO patients who underwent pyeloplasty using a domestic single-port ser-pentine-arm robotic surgical system(Beijing Surgerii Robotics Co.,Ltd.)in Beijing Children's Hospital from November 2023 to February 2024 were retrospectively collected.The patients who were not receiving surgical treatment for the first time,had hydronephrosis caused by other reasons(such as ureterovesical junction obstruction,posterior urethral valve,urinary tract stones,vesicoureteral reflux,ureterocele,etc.),had other urinary tract malformations(such as duplicated kidneys,congenital renal dysplasia,etc.),had severe atrophy of the affected kidney,severe urinary tract infection or severe renal insufficien-cy were excluded.All the surgeries were performed through the umbilicus and abdominal cavity,and the operation time,number of intraoperative incisions,incision size,intraoperative blood loss,and peri-operative complications were recorded.Statistical analysis was performed to compare changes in the an-teroposterior pelvic diameter(APD)and renal cortical thickness before surgery and 6 months postopera-tively.Results:A total of 10 patients were included(8 males and 2 females),with an average age of(10.20±3.12)years.Nine patients were on the left side and one patient was on the right side.The average height was(142.0±17.8)cm and the average weight was(37.6±17.9)kg.All the patients underwent surgery using the domestic single-port robotic surgery system,and no patient was converted to open pyeloplasty.The total operation time was(237±96)min,and the operation time on the operating table was(162.0±69.3)min.The intraoperative blood loss was 5.00(2.25,5.00)mL.No compli-cations,such as bleeding,urine extravasation,fever,and poor wound healing occurred during the perioperative period.Compared with the preoperative measurements,the APD was significantly shortened postoperatively(P=0.005),and the renal cortical thickness significantly increased(P=0.011).Con-clusion:The domestic single-port serpentine arm robotic surgical system is safe and feasible for UPJO pyeloplasty in children,with good surgical results,and can be promoted and applied in most domestic medical centers.

Background and Aims:Intrahepatic cholangiocarcinoma(ICC)is a highly malignant liver tumor,with an increasing incidence worldwide,particularly in Asia.Although radical surgical resection is currently the only potentially curative treatment,the high recurrence rate and low postoperative overall survival(OS)rate of ICC remain major clinical challenges.Adjuvant therapy(AT)and neoadjuvant therapy(NAT)are important strategies to reduce postoperative recurrence and prolong OS.Several studies have shown certain efficacy of these treatments.However,the specific efficacy and safety of combined NAT and AT in ICC treatment require further validation.This study was conducted to evaluate the value of combining NAT and AT in improving the therapeutic outcomes of ICC patients through a multicenter retrospective analysis,so as to provide scientific evidence for optimizing treatment strategies.Methods:The clinicopathologic data of 576 patients with ICC who underwent radical resection and were pathologically confirmed from 13 hospitals in China between December 2011 and December 2017 were retrospectively collected.Patients were grouped based on their treatment modality:NAT+AT group,AT group,and non-NAT/AT group.The three patient groups were matched pairwise in a 1∶1 ratio using propensity score matching(PSM)to balance baseline data.The Kaplan-Meier method was used to analyze OS and disease-free survival(DFS),and subgroup analyses were conducted according to the 8th edition of the AJCC TNM staging system.Results:A total of 395 ICC patients were included in the final analysis,with 42 patients(10.6%)in the NAT+AT group,62 patients(15.7%)in the AT group,and 291 patients(73.7%)in the non-NAT/AT group.Before PSM,significant differences were observed between groups in terms of CA19-9,liver function Child-Pugh classification,intraoperative blood loss,surgical margin,differentiation grade,vascular invasion,ECOG score,and lymph node dissection ratio(all P<0.05).After PSM,there were no significant differences in baseline characteristics between the groups(all P>0.05).After matching,the median OS and DFS in the NAT+AT group were significantly better than in the AT and non-NAT/AT groups(both P<0.05),while there were no significant differences in OS and DFS between the AT and non-NAT/AT groups(both P>0.05).Subgroup analysis showed that in TNM stage I patients,DFS in the NAT+AT group was significantly better than in the non-NAT/AT group(P<0.05),but OS was not significantly different(P>0.05).In TNM stage Ⅱ and Ⅲ patients,both OS and DFS in the NAT+AT and AT groups were significantly better than in the non-NAT/AT group(both P<0.05),and DFS in the NAT+AT group was significantly better than in the AT group in TNM stage Ⅲ patients(P<0.05).Conclusion:NAT combined with AT provides better survival benefits for patients with locally advanced ICC,but its benefit for early-stage ICC patients is limited.However,the retrospective design and sample size limitations of this study may affect the stability of the results,and future large-sample,multicenter,prospective studies are needed for further validation.
