Objective To identify specific behaviors detrimental to language development in parent-child inter-actions among Mandarin-speaking infants and toddlers with language delays,and to provide a foundation for develo-ping parent-involved early intervention programs that enhance language acquisition.Methods A qualitative research design was used,employing interaction analysis and categorical analysis methods.Observations from 30 parent-child interaction videos involving children with delayed language development were analyzed to identify common detrimen-tal behaviors(coding).The validity of the qualitative findings was tested by analyzing 108 parent-child where low-quality parental interactions were identified and provided with five rounds of constructive feedback.Results Two major categories of detrimental behaviors with three aspects and a total of 10 issues were identified:5 issues related to parental interaction skills,3 issues related to mutual influences between parent and child,and 2 issues related to the interaction environment.After 5 rounds of feedback,detrimental behaviors in the 108 parent-child pairs im-proved significantly,with 8 behaviors met the 80％stability standard.Conclusion The study identified and catego-rized behaviors in parent-child interactions that hinder language development in children with language delays.Video-based behavior analysis and feedback can enhance parental interaction skills and create a conductive environ-ment for early language development.

Background:Bushen Zhuanggu Formula(BZF),derived from the classic Yougui Pills,has shown favorable clinical efficacy in treating advanced nontraumatic osteonecrosis of the femoral head(NONFH),particularly by promoting bone repair.However,its underlying mechanisms remain unclear.Objective:This study aimed to explore the mechanisms by which BZF promotes bone repair in advanced NONFH.Materials and methods:A total of 518 potential BZF targets were identified from the ETCM v2.0 database.Transcriptomic profiling of clinical cohorts revealed 485 differentially expressed genes in advanced NONFH patients compared to healthy controls.A drug target-disease gene interaction network was constructed to identify candidate BZF targets involved in NONFH pathogenesis.In vivo experiments were conducted to validate the effects of BZF in a rat model of advanced NONFH.Results:Network analysis identified key pathways associated with blood circulation obstruction,immune-inflammatory imbalance,and abnormal bone metabolism.Protein kinase C alpha(PKCA),Ras proto-oncogene(RAS),mitogen-activated protein kinase 3(ERK),ETS proto-oncogene 1(ETS1),and receptor activator of nuclear factor-κB ligand(RANKL)formed a signaling axis implicated in NONFH pathogenesis.BZF treatment alleviated joint inflammation,preserved trabecular bone morphology,reduced bone loss,and promoted bone repair.Mechanistically,BZF significantly downregulated the expression of PKCA,RAS,ERK,ETS1,and RANKL,improved blood circulation,and inhibited osteoclast activation while promoting osteoblast activation.Conclusion:BZF may promote bone repair in advanced NONFH by enhancing blood circulation and modulating the PKC-RAS-ERK-ETS1-RANKL signaling axis,thereby reversing dysregulated bone metabolism.

Cancer cachexia is a complex syndrome caused by multiple factors,which seriously affects the quality of life and prognosis of patients.Its overall pathogenesis is related to the deficiency of spleen qi,insufficiency of kidney essence,internal generation of turbid toxins,and the obstruction of the production of qi,blood and essential qi,which cannot nourish the muscles and bones.Under the guidance of the dynamic diagnosis and treatment system of"spleen and kidney exhaustion as the root cause and internal accumulation of turbid toxins as the manifestation",the overall regulation is carried out from four dimensions:opening and closing the spleen and stomach,nourishing the kidney and promoting transportation,transforming turbid toxins and detoxification,and tonifying qi and nourishing yin.It has shown unique value in the intervention of cancer cachexia and can provide ideas and references for the clinical practice of TCM in treating cancer cachexia.

However, its underlying mechanisms remain unclear. Objective: This study aimed to explore the mechanisms by which BZF promotes bone repair in advanced NONFH. Materials and methods: A total of 518 potential BZF targets were identified from the ETCM v2.0 database. Transcriptomic profiling of clinical cohorts revealed 485 differentially expressed genes in advanced NONFH patients compared to healthy controls. A drug target-disease gene interaction network was constructed to identify candidate BZF targets involved in NONFH pathogenesis. In vivo experiments were conducted to validate the effects of BZF in a rat model of advanced NONFH. Results: Network analysis identified key pathways associated with blood circulation obstruction, immune-inflammatory imbalance, and abnormal bone metabolism. Protein kinase C alpha (PKCA), Ras proto-oncogene (RAS), mitogen-activated protein kinase 3(ERK), ETS proto-oncogene 1 (ETS1), and receptor activator of nuclear factor-κB ligand (RANKL) formed a signaling axis implicated in NONFH pathogenesis. BZF treatment alleviated joint inflammation, preserved trabecular bone morphology, reduced bone loss, and promoted bone repair. Mechanistically, BZF significantly downregulated the expression of PKCA, RAS, ERK, ETS1, and RANKL, improved blood circulation, and inhibited osteoclast activation while promoting osteoblast activation. Conclusion: BZF may promote bone repair in advanced NONFH by enhancing blood circulation and modulating the PKC-RAS-ERK-ETS1-RANKL signaling axis, thereby reversing dysregulated bone metabolism.

Objective: To investigate the effect of compound sophora flavescens injection on T helper cells 17 (Th17), regulatory T-cells (Treg cells) and the related cytokines in lung cancer patients with cirrhosis. Methods: A total of 63 patients with early non-small cell lung cancer and cirrhosis in Shouguang People's Hospital of Shandong Province from January 2016 to January 2018 were selected. All patients were scheduled to undergo surgical treatment. The patients were randomly divided into observation group (33 cases) and control group (30 cases) according to the random number table method. The patients in the control group were treated with liver protection, and the patients in the observation group were given compound sophora flavescens on the basis of the control group. After 3 months of treatment, the changes of liver fibrosis index, the levels of Th17 and Treg cells in peripheral blood and the changes of interleukin (IL)-10, IL-17, IL-6, and transforming growth factor (TGF)-β in serum were compared between the two groups. Results: After treatment, the alanine aminotransferase (ALT) of 15 cases (45.45%) in the observation group were normalized and 6 cases (20.00%) in the control group were normalized. There was a significant difference in ALT normalization rate between the two groups (P < 0.05). The levels of serum laminin (LN) and hyaluronic acid (HA) in the two groups after treatment were lower than those before treatment (all P < 0.05), and the serum LN [(156.74±30.52) ng/ml] and HA [(179.56±25.32) ng/ml] in the observation group after treatment was lower than those in the control group [(210.58±39.42) ng/ml and (203.75±28.79) ng/ml] (t values were 18.236 and 12.184, both P < 0.01). There was no significant difference in the level changes of type Ⅲ procollagen and type Ⅳ collagen between the two groups before and after treatment (all P > 0.05). After treatment, the levels of Th17 and Th17/Treg increased and the level of Treg cells decreased (all P < 0.05). After treatment, the levels of Th17 [(1.32±0.18)%] and Th17/Treg (0.23±0.04) in the observation group were higher than those in the control group [(1.21±0.17)% and 0.20±0.03] (t values were 3.201 and 1.087, both P < 0.01), while the level of Treg cells in the observation group was lower than that in the control group (P < 0.05). After treatment, the serum levels of IL-10, IL-17, IL-6, and TGF-β in the two groups were lower than those before treatment (all P < 0.05), and their levels in the observation group were lower than those in the control group (all P < 0.05). Conclusion Compound sophora flavescens injection can improve the liver function and fibrosis index of patients with lung cancer and cirrhosis, and it can regulate the levels of Th17, Treg cells and their related factors, which can be used as a clinical adjuvant.
