OBJECTIVE To explore a model for constructing a platform for medical institution formulation and provide insights for promoting their development. METHODS By systematically reviewing the development status and challenges of medical institution preparations in China, and based on the theory of industry-university-research collaborative innovation, the organizational structure, collaborative processes, and safeguard mechanisms of the platform were designed. RESULTS & CONCLUSIONS Medical institution formulations in China mainly faced challenges such as weak research and development (R&D) capacity, uneven quality standards, and blocked transformation pathways. This study established a full-chain, whole- industry collaborative innovation network covering the government, medical institutions, universities/research institutes, pharmaceutical enterprises, and the market, forming a new “government-industry-university-research-application” five-in-one platform model for medical institution formulations. By establishing mechanisms such as multi-entity collaborative cooperation, full- chain intellectual property management, contribution-based benefit distribution, staged risk-sharing, and third-party evaluation, the model clarified the responsibilities and collaborative pathways of all parties. The new model highlights the whole-process transformation of clinical experience-based prescriptions, enabling precise alignment between clinical needs and technological R&D, as well as between preparation achievements and industrial transformation. While breaking down the barriers of traditional platform construction, it effectively achieves optimal resource allocation and complementary advantages, addresses problems emerging in the development of medical institution preparations, and provides reference value for the formulation of relevant systems.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

Objective:
To evaluate the performance of 5T magnetic resonance imaging (MRI) in visualizing dental pulp and periodontal ligament (PDL) tissues in vivo in the young adult population, thereby providing a basis for the application of high-field MRI technology in clinical oral examinations.
Methods:
The study was approved by the Ethics Committee of the hospital. A total of 15 healthy volunteers (413 permanent teeth altogether) were recruited and underwent full-mouth 5T MRI scans. Among them, six volunteers (168 permanent teeth) also received both 3T MRI and cone-beam computed tomography (CBCT) scans. Two dental specialists independently evaluated the imaging quality of the dental pulp and PDL on the images using a 5-point Likert scale and recorded the number of detectable root canals for each tooth. Inter-rater agreement was assessed using weighted kappa statistics and intraclass correlation coefficient (ICC). Non-parametric tests were employed to compare differences in imaging performance among different tissue structures, tooth positions, and imaging modalities.
Results:
5T MRI can achieve in vivo imaging for most dental pulp tissues and partial periodontal membrane structures. There was a high level of agreement between the two raters in their imaging scores for the dental pulp and PDL (dental pulp κ = 0.934, PDL κ = 0.737). The imaging scores for dental pulp were significantly higher than those for PDL (P < 0.001), and the scores for molar dental pulp were lower than those for premolars and anterior teeth. In the multimodal comparison involving six volunteers, the raters showed good consistency in scoring dental pulp and PDL imaging across 5T MRI, 3T MRI, and CBCT, as well as in root canal counts (5T MRI for dental pulp κ = 0.971, 3T MRI for dental pulp κ = 0.933, CBCT for dental pulp κ = 0.964; 5T MRI for PDL κ = 0.625, 3T MRI for PDL κ = 0.667, CBCT for PDL κ = 0.571; ICC for root canal counts all ≥ 0.990). The imaging scores for dental pulp and PDL using 5T MRI were significantly higher than those using 3T MRI (dental pulp: P < 0.001; PDL: P = 0.022), but there was no statistically significant difference in the detection rate of the number of root canals between the two (P > 0.05). Although the imaging scores for dental pulp and PDL as well as the detection rate of the number of root canals with 5T MRI were inferior to those with CBCT (dental pulp: P < 0.001; PDL: P = 0.02; number of root canals: P < 0.05), 5T MRI can truly achieve "direct imaging" of these two soft tissues.
Conclusion
5T MRI enables effective in vivo direct imaging of dental pulp and PDL tissues in the young adult population, indicating its potential clinical application value in the diagnosis and treatment of pulp and periodontal diseases.

ObjectiveTo establish a reliable chronic obstructive pulmonary disease (COPD) mouse model based on a self-developed multichannel automatic control system for long-term continuous cigarette smoke exposure in small animals using a novel continuous cigarette smoke exposure method, and to conduct phenotypic evaluation and analysis, thereby providing an animal experimental basis for investigating COPD pathogenesis and prevention strategies. MethodsTwenty male C57BL/6J mice aged 6 weeks were randomly and equally divided into a control group and a model group. The model group (n=10) underwent 6 h of continuous cigarette smoke exposure daily (6 cigarettes per day for 12 consecutive weeks), while the control group (n=10) received no intervention. Body weight was monitored biweekly. Post-exposure, in vivo micro-CT imaging was performed. After euthanasia, serum and bronchoalveolar lavage fluid (BALF) levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were quantified by ELISA. Lung tissues underwent H&E and Masson's trichrome staining to observe changes in lung morphology and inflammatory cell infiltration, and the mean linear intercept (MLI) was calculated, thereby comprehensively evaluating the clinical features of COPD in the mouse model. ResultsCompared with the control group, the model group showed significantly reduced body weight (P<0.01) from the fourth week. Compared with the control group, IL-6 level in the serum and BALF of the model group increased by 27.2% and 140.0%, respectively (P<0.01). TNF-α level in the serum and bronchoalveolar lavage fluid of the model group increased by 16.7% (P<0.01) and 19.3% (P<0.05), respectively. Histopathological examination revealed alveolar wall thinning, septal rupture, emphysematous bullae formation, reduced alveolar count, bronchial wall thickening with lumen narrowing, and inflammatory cell infiltration. MLI was significantly elevated (P<0.01). Masson's staining confirmed collagen deposition and bronchial remodeling. Micro-CT demonstrated localized high-density shadows exhibiting typical features of chronic bronchitis. Conclusion The self-developed device enables long-term continuous smoke exposure, and the successfully established COPD mouse model exhibits pathological features highly consistent with clinical manifestations, offering an efficient and reliable tool for COPD research.

ObjectiveTo explore the mechanism of Yinchenhao Tang regulating the tumor necrosis factor receptor superfamily member 6 (Fas)/cysteine protease-8 (Caspase-8)/cysteine protease-3 (Caspase-3) signaling pathway to inhibit hepatocyte apoptosis and improve cholestatic liver injury (CLI). MethodsAmong 48 Wistar rats,12 rats were randomly selected as the blank group,and the other rats were administered alpha-naphthalene isothiocyanate (ANIT) by gavage to induce a CLI model. The modeling rats were randomly divided into the model group, the ursodeoxycholic acid group(0.1 g·kg-1) and the Yinchenhao Tang group(9.23 g·kg-1),with 12 rats in each group. The rats in each group were given corresponding drugs by gavage for three consecutive days. The levels of alanine aminotransferase (ALT),aspartate aminotransferase (AST),alkaline phosphatase (ALP),gamma-glutamyl transpeptidase (γ-GT),total bilirubin (TBil) and total bile acid (TBA) in serum were detected. The levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in liver tissue were detected. The histopathological changes of the liver were observed by hematoxylin-eosin (HE) staining. The protein and mRNA expressions of Fas,Caspase-8,Caspase-3,B-cell lymphoma-2 (Bcl-2) associated X protein (Bax) and Bcl-2 in liver tissue were detected by Western blot and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultsCompared with those in the blank group,the levels of ALT,AST,ALP,γ-GT,TBA and TBil in serum of the model group were significantly increased (P<0.01). The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly increased (P<0.01). The arrangement of hepatocytes was disordered,and inflammatory cell infiltration and bile duct epithelial cell proliferation were observed. The protein and mRNA expressions of Fas,Caspase-8,Caspase-3 and Bax in liver tissue were significantly increased(P<0.05,P<0.01),while the protein and mRNA expressions of Bcl-2 were significantly decreased (P<0.05,P<0.01). Compared with those in the model group,the levels of ALP,γ-GT,TBA and TBil in the serum of rats in the ursodeoxycholic acid group were significantly decreased. The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly decreased(P<0.05,P<0.01). The protein and mRNA expressions of Fas,Caspase-8,Caspase-3 and Bax in liver tissue were significantly decreased (P<0.05,P<0.01),while the mRNA expression of Bcl-2 was significantly increased (P<0.05,). The levels of ALT,AST,γ-GT,TBA and TBil in the serum of rats in the Yinchenhao Tang group were significantly decreased (P<0.01). The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly decreased (P<0.05,P<0.01). The protein expression of Fas and Bax and the mRNA expression of Fas,Caspase-8,Caspase-3 and Bax in liver tissue were significantly decreased (P<0.05,P<0.01),while the protein and mRNA expression of Bcl-2 were significantly increased (P<0.05,P<0.01). Hepatocyte injury,inflammatory cell infiltration and proliferation of bile duct epithelial cells were reduced. ConclusionYinchenhao Tang can ameliorate CLI,and its mechanism may be related to inhibiting hepatocyte apoptosis mediated by the Fas/Caspase-8/Caspase-3 signaling pathway.

ObjectiveTo study the mechanism of Yinchenhao Tang on the improvement of cholestatic liver injury (CLI) by inhibiting toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear transcription factor-κB (NF-κB) pathway via regulating farnesol X receptor (FXR). MethodsA total of 40 Wistar male rats were randomly selected, with 10 as a blank group,and the remaining rats were subjected to the CLI model induced by alpha-naphthalene isothiocyanate (ANIT). After modeling,they were randomly divided into the model group, the ursodeoxycholic acid (0.1 g·kg-1) group and the Yinchenhao Tang (9.23 g·kg-1) group,with 10 animals in each group. Each administration group was given the corresponding drug by intragastric administration for three consecutive days. Alanine aminotransferase (ALT),aspartate aminotransferase (AST),alkaline phosphatase (ALP),γ-glutamyl transpeptidase (γ-GT),total bile acid (TBA),total bilirubin (TBil) and direct bilirubin (DBil) levels in serum were detected. Tumor necrosis factor-α (TNF-α),interleukin-1β (IL-1β),and interleukin-6 (IL-6) levels in liver tissue were detected. Real-time PCR was used to detect the mRNA expression of FXR,TLR4,MyD88,NF-κB,F4/80,TNF-α,IL-1β and IL-6 in liver tissue. Western blot was used to detect protein expression of FXR,TLR4,MyD88 and NF-κB in liver tissue. The histopathological changes of the liver were observed by hematoxylin-eosin (HE) staining. ResultsCompared with those in the blank group,ALT,AST,ALP,γ-GT,TBA,TBil and DBil levels in serum of rats in the model group were significantly increased (P<0.01). The levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were significantly increased (P<0.01),and the mRNA and protein expressions of FXR in liver tissue were decreased (P<0.01). The mRNA and protein expressions of TLR4,MyD88 and NF-κB and the mRNA expression of F4/80 were obviously increased (P<0.05,P<0.01). Hepatic histopathology showed inflammatory cell infiltration and proliferative changes of bile duct epithelial cells. Compared with those in the model group,ALT,ALP,γ-GT,TBA,TBil and DBil levels in serum of rats in the ursodeoxycholic acid group were obviously decreased (P<0.05,P<0.01),and the levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were obviously decreased (P<0.05,P<0.01). The mRNA and protein expressions of TLR4,MyD88 and NF-κB and the mRNA expression of F4/80 in liver tissue were obviously decreased (P<0.05,P<0.01). ALT,AST,ALP,γ-GT,TBA,TBil and DBil levels in the serum of rats in the Yinchenhao Tang group were obviously decreased (P<0.05,P<0.01),and the levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were obviously decreased (P<0.01). The mRNA and protein expressions of FXR in liver tissue were significantly increased,and the mRNA expressions of TLR4,MyD88,NF-κB,and F4/80, as well as the protein expressions of TLR4 and NF-κB were obviously decreased (P<0.05,P<0.01). The inflammatory cell infiltration of liver tissue and the proliferation of bile duct epithelial cells decreased. ConclusionYinchenhao Tang has an obvious protective effect on CLI,and its mechanism may be related to regulating FXR to inhibit TLR4/MyD88/NF-κB pathway-mediated inflammatory response.

ObjectiveTo explore the mechanism by which Yinchenhao Tang intervenes in α-naphthylisothiocyanate (ANIT)-induced cholestatic liver injury by regulating the Takeda G-protein-coupled receptor 5(TGR5)/NOD-like receptor protein 3(NLRP3)/cysteine aspartate-specific protease-1 (Caspase-1) pyroptosis signaling pathway. MethodsForty male Wistar rats were randomly assigned into blank, model, ursodeoxycholic acid, and Yinchenhao Tang groups. Except the blank group, other groups were treated with ANIT dissolved in olive oil for the modeling of cholestatic liver injury. Ursodeoxycholic acid (0.1 g·kg-1) and Yinchenhao Tang (9.23 g·kg-1) were administered by gavage. The blank group and the model group were administrated with the same amount of pure water, once a day for 3 days. The blood and liver tissue samples were collected, and the serum levels of liver function indicators were measured by an automatic biochemical analyzer. Hematoxylin-eosin staining was employed to observe the pathological changes of the liver. The levels of interleukin (IL)-1β and IL-18 in the liver tissue were determined by ELISA. The mRNA levels of IL-1β, IL-18, TGR5, NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), Caspase-1, and GSDMD in the liver tissue were assessed by Real-time PCR. The protein levels of TGR5, NLRP3, ASC, Caspase-1, and GSDMD in the liver tissue were determined by Western blot. ResultsCompared with the blank group, the model group showed elevated levels of alanine amino-transferase (ALT), aspartate transferase (AST), alkaline phosphatase (ALP), total bile acid (TBA), and total bilirubin (TBil) in the serum (P<0.01), inflammatory cell infiltration, hepatocyte swelling, and bile duct epithelial cell proliferation in the liver, raised levels of IL-1β and IL-18 in the liver tissue (P<0.01), down-regulated mRNA and protein levels of TGR5 (P<0.01), up-regulated mRNA levels of IL-18 (P<0.01), ASC (P<0.01), Caspase-1 (P<0.01), GSDMD (P<0.01), IL-1β (P<0.05), and NLRP3 (P<0.05), and up-regulated protein levels of NLRP3 (P<0.01), ASC (P<0.01), Caspase-1 (P<0.01), and GSDMD (P<0.05). Compared with the model group, the ursodeoxycholic acid group showed declined levels of AST (P<0.01), TBA (P<0.01), TBil (P<0.01), and ALT (P<0.05) in the serum, lowered levels of IL-1β and IL-18 in the liver tissue (P<0.01), down-regulated mRNA levels of NLRP3 (P<0.01), Caspase-1 (P<0.01), GSDMD (P<0.01), IL-1β (P<0.05), IL-18 (P<0.05), and ASC (P<0.05), up-regulated mRNA and protein levels of TGR5 (P<0.05), and down-regulated protein levels of NLRP3, ASC, Caspase-1, and GSDMD (P<0.05). Compared with the model group, the Yinchenhao Tang group showed lowered levels of ALT, AST, ALP, TBA, and TBil in the serum (P<0.01), declined levels of IL-1β and IL-18 in the liver tissue (P<0.01), down-regulated mRNA levels of IL-1β (P<0.01), NLRP3 (P<0.01), ASC (P<0.01), Caspase-1 (P<0.01), GSDMD (P<0.01), and IL-18 (P<0.05), up-regulated mRNA and protein levels of TGR5 (P<0.01), and down-regulated protein levels of Caspase-1 and GSDMD (P<0.05). The liver tissue of the administration groups showed reduced infiltration of inflammatory cells, reduced swelling of hepatocytes, and alleviated proliferation of bile duct epithelial cells. ConclusionYinchenhao Tang can ameliorate ANIT-induced cholestatic liver injury by regulating the hepatocyte pyroptosis mediated by the TGR5/NLRP3/Caspase-1 signaling pathway.

Cholestatic liver injury refers to the bile production, secretion, and excretion disorder caused by various reasons. It induces liver injury, metabolic disorders, and dysfunction of the hepatobiliary system, which can further develop into liver fibrosis, cirrhosis, liver failure, and even death. At present, the preferred drug for clinical treatment is ursodeoxycholic acid, which, however, induces adverse reactions and is intolerant in some patients. Yinchenhao Tang is a representative prescription of traditional Chinese medicine for the treatment of jaundice due to Yang jaundice. It has the effects of clearing heat, eliminating dampness, and removing jaundice and has shown good therapeutic effect in long-term clinical application. Modern pharmacological studies have found that this prescription has anti-inflammatory, anti-oxidation, bile acid balance-regulating, hepatocyte apoptosis-inhibiting and other liver-protecting effects. This paper reviews the relevant clinical and animal experimental studies on Yinchenhao Tang in the treatment of cholestatic liver injury in recent years. Yinchenhao Tang can intervene in the progression of cholestatic liver injury by regulating bile acid metabolism and excretion, reducing inflammatory response, inhibiting oxidative stress, alleviating endoplasmic reticulum stress, inhibiting hepatocyte apoptosis, and protecting intestinal mucosal barrier. This paper systematically expounds the molecular mechanisms by which Yinchenhao Tang regulates cholestatic liver injury that are confirmed by current research, aiming to provide reference for the clinical application and in-depth study of Yinchenhao Tang.

ObjectiveGastrodia elata has evolved ecological types with shortened rhizome internodes and diversified flower and fruit coloration in response to different altitudes. Studying the genetic mechanisms of different ecotype germplasm is significant for guiding variety breeding in different cultivation areas. MethodsThe bHLH gene family was identified based on the whole-genome datasets of G. elata f. elata and G. elata f. glauca. Subsequently, the gene family members were subject to analysis, including gene structure, chromosomal localization, cis-acting elements, gene synteny, and phylogeny. Combined with transcriptome data and quantitative Real-time PCR, the expression patterns of bHLH genes in the stems of the different G. elata ecotype germplasm were analyzed. Finally, correlation analysis was conducted between gene expression patterns and color to obtain the key bHLH genes regulating the color formation of stem. ResultsA total of 63 bHLH genes were identified in both G elata f. elata and G. elata f. glauca, unevenly distributed across 17 chromosomes and clustered into 16 subfamilies, with significant expansion in some family members. Obvious inversions of bHLH genes on the same chromosome and interchromosomal translocations were detected in the two ecotype germplasm. Among these genes, 12 bHLH genes (such as bHLH62-3 and bHLH74) were associated with the bright yellow color of G elata f. elata stem, while 9 bHLH genes (such as PIL13, UNE12, and bHLH130) were correlated with the red color of G. elata f. glauca stem. Compared to G. elata f. glauca, the bHLH48 expression level was significantly higher in flowers and scale leaves of G elata f. elata, and the bHLH62-3 expression level was significantly higher in all organs of G elata f. elata. ConclusionsFunctional pathway divergence of the bHLH family members has occurred across different chromosomes in G elata f. elata and G. elata f. glauca. Through synergism or antagonism with other genes, 21 bHLH genes participate in the coloration metabolic pathway regulation of stems, flowers, and fruits. Specifically, bHLH62-3 is involved in regulating stem color differentiation in the anthocyanin biosynthesis pathway of G. elata, thus relevant to the color formation of stem. Additionally, GebHLH48 positively regulates flowering-related pathways to promote the early-flowering phenotype of G. elata f. elata. These findings have laid the foundation for analyzing the genetic regulatory mechanisms underlying the color formation of the G. elata stem.

BackgroundAnxiety exhibits a rising prevalence among college students. Investigating the mechanisms through which family function relates to anxiety and examining the moderating role of emotion regulation strategies within this context hold substantial implications for promoting mental health among college students. However, existing research has not sufficiently elucidated the complex interplay among family function, emotion regulation, and anxiety among college students. Further research is warranted to clarify the underlying mechanisms linking family function to anxiety outcomes and to examine the potential moderating role of emotion regulation strategies in this causal pathway. ObjectiveTo explore the relationship between family function and anxiety among lower-grade college students, and to validate the moderating role of emotion regulation strategies in this relationship, thereby offering evidence-based insights for anxiety reduction interventions in this population. MethodsIn March 2023, a total of 1 980 first- and second-year students from a comprehensive university in Shanghai were selected using the cluster sampling method. A self-designed demographic questionnaire, the Emotion Regulation Questionnaire (ERQ), the Family Adaptability and Cohesion Evaluation Scale Ⅱ-Chinese Version (FACES Ⅱ-CV), and the Symptom Checklist-90 (SCL-90) were utilized for assessment. Pearson correlation analysis and Spearman correlation analysis were employed to test the correlations of each variable. Hierarchical linear regression analysis was conducted to certify the moderating role of emotion regulation strategies in the relationship between family function and anxiety. ResultsCompared with female students, male students scored significantly lower on ERQ cognitive reappraisal (t=-5.793, P<0.01) but significantly higher on ERQ expressive suppression (t=8.359, P<0.01). For lower-grade college students, scores on adaptability and cohesion subscales of FACES Ⅱ-CV showed a positive association with cognitive reappraisal in ERQ (r=0.251, 0.302, P<0.01), while simultaneously displaying negative correlations with both expressive suppression in ERQ (r=-0.113, -0.154, P<0.01) and anxiety in SCL-90 (r=-0.243, -0.202, P<0.01). Notably, anxiety scores in SCL-90 were inversely related to cognitive reappraisal scores in ERQ (r=-0.159, P<0.01) but directly associated with expressive suppression scores in ERQ (r=0.171, P<0.01). Hierarchical regression analysis indicated that cognitive reappraisal significantly moderated the relationship between family cohesion and anxiety (β=-0.421, P<0.01). ConclusionThe cognitive reappraisal strategy serves as a moderator in the relationship between family cohesion and anxiety, potentially mitigating the escalation of anxiety levels associated with family dysfunction.
