BACKGROUND:How to repair bone defect has been a clinical problem for a long time.The effective ingredients of traditional Chinese medicine have good biological activity and therapeutic effect,and the combination of effective ingredients of traditional Chinese medicine and tissue engineering materials has a broad prospect in the field of bone repair.The combination of different effective ingredients of traditional Chinese medicine and scaffolds has similarities in their functional relationships. OBJECTIVE:To collect the cases of the combinations of effective ingredients of traditional Chinese medicine and scaffolds,then analogize tissue engineering scaffolds and effective ingredients of traditional Chinese medicine into two types of traditional Chinese medicine that generate compatibility relationships based on the inspiration of the compatibility of seven emotions and summarize the relationship between the two based on their functional relationships. METHODS:Relevant articles from January 1998 to January 2024 were searched in PubMed and China National Knowledge Infrastructure(CNKI),using English search terms"traditional Chinese medicine,Chinese medicine,traditional Chinese medicine monomers,bone defect,bone repair,bone tissue engineering,tissue engineering,scaffold"and Chinese search terms"traditional Chinese medicine,effective ingredients of traditional Chinese medicine,traditional Chinese medicine monomers,bone tissue engineering,bone tissue engineering scaffold,scaffold,tissue engineering,bone defect,bone repair."A total of 88 articles were included for review and analysis. RESULTS AND CONCLUSION:(1)Both tissue engineering scaffold materials and active ingredients of traditional Chinese medicine have been widely used in the field of bone repair.Although they have obvious advantages in osteogenesis,there are still many shortcomings.Many studies are dedicated to preparing composite materials from the two,hoping to exert a detoxification and synergism through the interaction between the two.(2)Some drugs and materials can promote each other in osteogenesis,antibacterial,and promoting angiogenesis,enhancing their original effects.Inspired by the traditional concept of prescription compatibility,this article summarized it as a"Mutual promotion"relationship and provided examples to support it.(3)Some drugs can enhance the strength of materials,while some materials can achieve sustained release and controlled release effects,increase drug loading and stability,or achieve targeted delivery of drugs loaded on them.The article summarized this unilateral enhancement effect as a"Mutual assistance"relationship.(4)The combination of some traditional Chinese medicine and materials can reduce the toxic side effects of the other party.The article summarizes this detoxification relationship as"Mutual restraint and detoxification."(5)The article provided a new perspective on traditional Chinese medicine composite scaffolds,inspired by the seven emotions compatibility relationship and based on the classification of action relationships.It introduced traditional Chinese medicine concepts into the field of tissue engineering,providing new research ideas for subsequent researchers of composite scaffolds,and providing certain convenience in material selection and matching.

Objective To reveal the scientific output and trends in pulmonary nodules/early-stage lung cancer prediction models. Methods Publications on predictive models of pulmonary nodules/early lung cancer between January 1, 2002 and June 3, 2023 were retrieved and extracted from CNKI, Wanfang, VIP and Web of Science database. CiteSpace 6.1.R3 and VOSviewer 1.6.18 were used to analyze the hotspots and theme trends. Results A marked increase in the number of publications related to pulmonary nodules/early-stage lung cancer prediction models was observed. A total of 12581 authors from 2711 institutions in 64 countries/regions published 2139 documents in 566 academic journals in English. A total of 282 articles from 1256 authors were published in 176 journals in Chinese. The Chinese and English journals which published the most pulmonary nodules/early-stage lung cancer prediction model-related papers were Journal of Clinical Radiology and Frontiers in Oncology, respectively. Chest was the most frequently cited journal. China and the United States were the leading countries in the field of pulmonary nodules/early-stage lung cancer prediction models. The institutions represented by Fudan University had significant academic influence in the field. Analysis of keywords revealed that multi-omics, nomogram, machine learning and artificial intelligence were the current focus of research. Conclusion Over the last two decades, research on risk-prediction models for pulmonary nodules/early-stage lung cancer has attracted increasing attention. Prognosis, machine learning, artificial intelligence, nomogram, and multi-omics technologies are both current hotspots and future trends in this field. In the future, in-depth explorations using different omics should increase the sensitivity and accuracy of pulmonary nodules/early-stage lung cancer prediction models. More high-quality future studies should be conducted to validate the efficacy and safety of pulmonary nodules/early-stage lung cancer prediction models further and reduce the global burden of lung cancer.

Thyroid diseases are common clinical endocrine disorders， and their pathogenesis is generally considered to be closely related to genetic predisposition factors， immune system disorders， hormone levels， etc. Xiaoyaosan is widely used in the treatment of various thyroid diseases with excellent effects. This study summarized the relevant literature on the treatment of thyroid diseases with modified Xiaoyaosan prescriptions and their active ingredients from aspects such as theoretical analysis， clinical research， and mechanism research. Theoretical analysis revealed that Xiaoyaosan could not only disperse stagnated liver qi but also replenish deficient spleen Qi， which was consistent with the etiology and pathogenesis of thyroid diseases. Clinical studies found that Xiaoyaosan and its modified prescriptions could be widely used in the treatment of multiple thyroid diseases， such as hyperthyroidism， Hashimoto's thyroiditis， and thyroid nodules. Both the use of modified Xiaoyaosan alone and in combination with medications such as methimazole， propylthiouracil， and euthyrox could effectively improve patients' clinical symptoms. In the mechanism research， this study discovered that the whole formula of Xiaoyaosan and its modified prescriptions could inhibit inflammatory reactions， regulate immune balance， and delay liver damage during the treatment of thyroid diseases. The research on Xiaoyaosan for treating thyroid diseases mainly focused on thyroid cancer， autoimmune thyroiditis， hyperthyroidism， and hypothyroidism. The mechanisms of action mainly involved promoting cell apoptosis， inhibiting cell proliferation and migration， arresting the cell cycle， and regulating thyroid hormone levels. In conclusion， this study systematically combs and summarizes the research status of Xiaoyaosan in treating thyroid diseases through literature retrieval， aiming to provide new perspectives and new ideas for the prevention and treatment of thyroid diseases with traditional Chinese medicine.

[Objective] To systematically evaluate the therapeutic effect of washed red blood cells and white suspended red blood cells on patients with autoimmune hemolytic anemia, and to provide reference for their clinical treatment. [Methods] CNKI, Wanfang, VIP, PubMed, Embase, Cochrane Library and other databases from the establishment of the database to August 2024 were searched, including the randomized controlled trials of washed red blood cells and white suspended red blood cells in the treatment of autoimmune hemolytic anemia that met the requirements. After literature screening, data extraction and quality evaluation, meta-analysis was performed using Review manager 5.3 software and Stata 15.1 software to analyze the therapeutic effect of blood transfusion in the primary outcome, hematological indicators (Hb, Ret, RBC, and TBIL) of the two groups after blood transfusion and the occurrence of adverse blood transfusion reactions. [Results] After screening, 10 literatures meeting the criteria were retrieved, and a total of 753 patients with autoimmune hemolytic anemia were treated with washed red blood cell infusion in the observation group and white suspended red blood cell infusion in the control group. Meta-analysis suggested that there was no significant difference in the therapeutic effect of transfusion between patients who received washed red cells and those received white suspended red cells[SMD=1.16, 95%CI (0.87, 1.54), P>0.05]. The hematological indexes of the two groups after transfusion (Hb [SMD=0.04, 95%CI (-0.14, 0.22), P>0.05]、Ret[SMD=-0.15, 95%CI (-0.34, 0.03), P>0.05]、RBC[SMD=0.08, 95%CI (-0.10, 0.26), P>0.05] and TBIL [SMD=-0.02, 95%CI (-0.18, 0.15), P>0.05]) and the incidence of transfusion adverse reactions[SMD=0.8, 95%CI (0.47, 1.39), P>0.05] were not significantly different. [Conclusion] Based on the current study, the efficacy and safety of infusion of washed red blood cells and white suspended red blood cells are comparable in patients with autoimmune hemolytic anemia. However, considering the simple preparation process of washed red blood cells and the low price, infusion of washed red blood cells is recommended for patients with autoimmune hemolytic anemia.

ObjectiveTo investigate the effects of Zuoguiwan on osteoclast activation induced by breast cancer and its mechanism. MethodsTo simulate breast cancer-induced osteoclastic bone metastasis， RAW264.7 cells were cultured in conditioned medium containing 50% supernatant of MDA-MB-231 breast cancer cells. The dosages of Zuoguiwan used in the experiment were sera containing 5% and 10% Zuoguiwan. Tartrate-resistant acid phosphatase （TRAP） staining was used to detect osteoclast activation. Enzyme-linked immunosorbent assay （ELISA） was used to measure Cathepsin K secretion from RAW264.7 cells. Real-time quantitative polymerase chain reaction （PCR） was used to detect the mRNA expression levels of osteocalcin （OCN） and bone sialoprotein （BSP）. Immunoprecipitation was employed to detect the interaction between Runt-related transcription factor 2 （Runx2） and core binding factor β subunit （CBF-β）. Western blot was used to assess the protein expression of Runx2， phosphorylated Runx2 （p-Runx2）， extracellular signal-regulated kinases 1/2 （ERK1/2）， p-ERK1/2， p38 mitogen-activated protein kinase （MAPK）， p-p38 MAPK， and CBF-β. ResultsCompared with the blank group， the MDA-MB-231 cell supernatant group showed a significant increase in TRAP-positive cell counts and Cathepsin K secretion. Meanwhile， the expression levels of p-Runx2， Runx2-CBF-β interaction， BSP and OCN mRNA， p-p38 MAPK， and p-ERK1/2 proteins were significantly decreased （P<0.01）. Compared with the MDA-MB-231 cell supernatant group， Zuoguiwan-containing sera significantly reduced TRAP-positive cell counts and Cathepsin K secretion （P<0.01）， significantly increased p-Runx2， BSP and OCN mRNA expression， as well as p-p38 MAPK and p-ERK1/2 protein levels， and promoted the interaction between Runx2 and CBF-β （P<0.01）. No significant change in Runx2 expression was observed. Compared to the blank group， the BVD-523 group showed significantly lower expression of p-p38 MAPK and p-ERK1/2 proteins （P<0.01）. Compared with the BVD-523 group， both low and high concentration Zuoguiwan-containing sera groups showed significantly higher p-p38 MAPK expression （P<0.01）， and the high concentration Zuoguiwan group also exhibited a significant increase in p-ERK1/2 expression （P<0.01）， while no statistical difference was found in the low-dose group. ConclusionZuoguiwan inhibits osteoclast activation by inducing phosphorylation of the key transcriptional regulator Runx2 in intra-osteoclast bone formation， and this process is closely associated with the activation of the p38 MAPK/ERK signaling pathway.

ObjectiveTo analyze the trend of lung cancer incidence in Fenghua District, Ningbo City of Zhejiang Province from 2009 to 2023, and to estimate the age-period- cohort effects of incidence rate, so as to provide scientific basis for the formulation of lung cancer prevention and control measures in Fenghua District. MethodsJoinpoint software was utilized to analyze the trends and calculate the average annual percentage change (AAPC) of lung cancer incidence based on the tumor incidence surveillance data from Fenghua District, 2009‒2023. The age-period-cohort (APC) model for lung cancer incidence was analyzed using STATA 17.0 software, and net drift and local drift of lung cancer incidence rates were analyzed using online analytical tools. ResultsThe incidence of lung cancer in Fenghua District showed an overall upward trend from 2009 to 2023, with the standardized incidence rate increasing from 45.05/100 000 in 2009 to 108.20/100 000 in 2023(AAPC=7.05%, P<0.05). The increase in the standardized incidence rate for females (AAPC=12.72%, P<0.05) was higher than that for males (AAPC=2.97%, P<0.05). The overall net drift in lung cancer incidence for residents of Fenghua District was 11.71%, with the net drift for females (16.54%) being higher than that for males (6.64%). The local drift in lung cancer incidence among different age groups ranged from -3.37% to 35.18%. The results of APC model showed that the risk of lung cancer incidence increased and then decreased with age, with the highest age effect coefficient observed in the 65‒69 years age group at 1.08. The period effect showed a gradually increasing trend in lung cancer incidence risk with the progression of time, and the period effect coefficient in 2019‒2023 (0.46) was higher than that in 2009‒2013 (-0.39), increasing by 217.95%. The cohort effect coefficient showed a trend of first decreasing and then increasing with the expansion of the birth cohort, in which the lowest cohort effect coefficient was -1.07 observed in the birth cohort of 1964‒1968 and the highest cohort effect coefficient was 1.77 in the birth cohort of 1924‒1928. ConclusionThe incidence of lung cancer in Fenghua District shows an upward trend from 2009 to 2023, with a higher increase in incidence rates among females than that in males. The risk of lung cancer incidence exists a trend of increasing and then decreasing with age growth. With the progression of time, the risk of lung cancer incidence shows a gradually increasing trend. However, with the expansion the birth cohort, the risk of lung cancer incidence demonstrates a trend of first decreasing and then increasing.

BackgroundCurrently， the problem of depressed mood in college students is becoming more prominent. The experience of childhood maltreatment is a significant contributor to depression among college students. Although the association between the two has been confirmed， the specific psychosocial mechanisms underlying how childhood maltreatment affects college students' mental health remain insufficiently evidenced. ObjectiveTo explore the mediating role of emotion regulation difficulties in the relationship between childhood maltreatment and depression among college students， and to investigate the moderated effects of psychological resilience and family socioeconomic status， aiming to provide references for improving depressive symptoms in college students. MethodsOn 14 March 2024， a cluster sampling method was employed to recruit 751 college students from a university in Heilongjiang Province. Participants were assessed with Childhood Trauma Questionnaire （CTQ）， Difficulties in Emotion Regulation Scale （DERS）， Patients' Health Questionnaire Depression Scale-9 item （PHQ-9）， 10-item Connor-Davidson Resilience Scale （CD-RISC-10） and Family Socioeconomic Status Questionnaire. Pearson correlation analysis was adopted to examine the correlation between the scores of scales. Model 4 and model 7 in Process 4.2 were used to test the mediating effects of emotional regulation difficulties and the moderated effects of psychological resilience and family socioeconomic status. Results① A total of 712 （94.81%） valid questionnaires were collected. ② College students' CTQ score was positively correlated with DERS score and PHQ-9 score （r=0.296， 0.507， P<0.01）， and negatively correlated with CD-RISC-10 score and Family Socioeconomic Status Questionnaire score （r=-0.148， -0.229， P<0.01）. ③ The indirect effect value of difficulties in emotion regulation on the relationship between childhood maltreatment and depression was 0.091 （95% CI： 0.018~0.046）， accounting for 17.95% of the total effect. ④ The first half of the mediation model "childhood maltreatment → difficulties in emotion regulation → depression" （childhood maltreatment → difficulties in emotion regulation） was moderated by psychological resilience （β=-0.030， t=-6.147， 95% CI： -0.040~-0.020） and family socioeconomic status （β=-0.051， t=-3.929， 95% CI： -0.077~-0.026）. ConclusionChildhood maltreatment exerts both a direct effect on college students' depression and an indirect effect through emotion regulation difficulties. The childhood maltreatment → emotion regulation difficulties pathway in this mediation model is moderated by psychological resilience and family socioeconomic status. ［Funded by Qiqihar Medical University Graduate Student Innovation Fund Project （number， QYYCX2023-48）； Special Research Fund Project for Young Doctors of Qiqihar Academy of Medical Sciences （number， QMSI2021B-08）］

This paper summarizes clinical experience in treating depression with a combined approach of acupuncture and herbal medicine under the guiding principle of deficiency and excess. Given the complex pathogenesis of depression， it is proposed that syndrome differentiation based on deficiency and excess should serve as the overarching principle. Acupuncture is prioritized， supplemented by Chinese herbal medicine. Acupuncture is based on the spirit-regulating protocol； for excess syndromes， it is combined with the calming and restoring protocol， while for deficiency syndromes， it is combined with the five zang organs tonification protocol. In cases of mixed deficiency and excess， the two protocols are alternated， and adjustments are made dynamically throughout the treatment based on syndrome evolution. Herbal prescriptions are also guided by the differentiation of deficiency and excess. For excess patterns， dispersion and clearance should be emphasized， focusing on soothing the liver， clearing heat， relieving irritability， regulating qi， transforming phlegm， and calming the mind； for deficiency patterns， tonification is emphasized， aiming to strengthen the spleen， nourish the blood， calm the spirit， tonify qi， and consolidate the root.
