Idiopathic pulmonary fibrosis （IPF） is a chronic interstitial lung disease characterized by dyspnea and progressive deterioration of lung function， which significantly impacts patients' quality of life and imposes a major burden on society. Although modern medicine has increasingly enriched the treatment options for pulmonary fibrosis， unfavorable factors such as high costs and significant side effects contribute to the persistently low survival rate of patients. Studies have shown that the occurrence and development of pulmonary fibrosis are closely related to abnormalities in multiple pathways. Among these， Rho/Rho-associated coiled-coil protein kinase （ROCK） plays a key role in the disease progression of IPF by regulating the cytoskeleton. This pathway not only transmits biochemical molecular signals that promote the progress of fibrosis but also responds to the biomechanical environment， such as the increased lung tissue stiffness caused by the deposition of extracellular matrix （ECM） during the process of pulmonary fibrosis. Therefore， research on this pathway is of great significance for the prevention and treatment of IPF. In recent years， traditional Chinese medicine （TCM） has shown remarkable effects in preventing and treating IPF. Many TCM compounds and active components can reduce the production of α-smooth muscle actin （α-SMA）， CollagenⅠ （ColⅠ）， ColⅢ， and inflammatory factors in lung tissue by regulating the Rho/ROCK signaling pathway. These compounds inhibit the transformation of fibroblasts （FBs） into myofibroblasts （MyoFBs）， intervening in the process of pulmonary fibrosis. Based on this， the article briefly reviews relevant research from recent years， discusses the key role of the Rho/ROCK pathway in pulmonary fibrosis from an interdisciplinary perspective， and summarizes the mechanisms through which TCM regulates Rho/ROCK to prevent and treat IPF， based on resources from PubMed， CNKI， and other databases， in order to provide important references for the broader clinical application of TCM in the prevention and treatment of IPF.

Cancer represents a major worldwide disease burden marked by escalating incidence and mortality. While therapeutic advances persist, developing safer and precisely targeted modalities remains imperative. Nanomedicines emerges as a transformative paradigm leveraging distinctive physicochemical properties to achieve tumor-specific drug delivery, controlled release, and tumor microenvironment modulation. By synergizing passive enhanced permeation and retention effect-driven accumulation and active ligand-mediated targeting, nanoplatforms enhance pharmacokinetics, promote tumor microenvironment enrichment, and improve cellular internalization while mitigating systemic toxicity. Despite revolutionizing cancer therapy through enhanced treatment efficacy and reduced adverse effects, translational challenges persist in manufacturing scalability, longterm biosafety, and cost-efficiency. This review systematically analyzes cutting-edge nanoplatforms, including polymeric, lipidic, biomimetic, albumin-based, peptide engineered, DNA origami, and inorganic nanocarriers, while evaluating their strategic advantages and technical limitations across three therapeutic domains: immunotherapy, chemotherapy, and radiotherapy. By assessing structure-function correlations and clinical translation barriers, this work establishes mechanistic and translational references to advance oncological nanomedicine development.

Objective To explore the roles of transcription factor E26 transformation-specific 1(ETS1)and F-box protein 45(FBXO45)in invasion and metastasis in hepatocellular carcinoma cells and the potential molecular mechanism.Methods Jaspar,hTFtarget and Cistrome transcription factor database prediction websites were used to predict the transcription factors of FBXO45.According to the intersection of the predicted results of each database,the expression of FBXO45 was detected after the candidate transcription factors were knockdown in HCCLM3 and Huh7 liver cancer cells,respectively.The most significant influence on FBXO45 expression was selected for further analysis,and chromatin immunoprecipitation assay(ChIP)was used to verify the binding to the FBXO45 promoter.Finally,the potential transcription factor of FBXO45 was identified.The effect of ETS1 overexpression on invasion and migration in HCCLM3 and Huh7 cells was detected by Transwell assay,and the expression levels of epithelial-mesenchymal transition(EMT)pathway proteins were detected by Western blot assay.The effects of FBXO45 knockdown on the invasion and migration under the condition of overexpression of ETS1 were also studied.Results Intersection of FBXO45 transcription factors identified 3 candidate transcription factors,ETS1,SPI1 and YY1.When the 3 transcription factors were knocked down in HCCLM3 and Huh7 cells,respectively,ETS1 knockdown significantly reduced the expression of FBXO45.According to the analysis of The Cancer Genome Atlas(TCGA)data and the Gene Expression Omnibus(GEO)data,the expression levels of ETS1 and FBXO45 were significantly positively correlated(R=0.31,P<0.000 1;R=0.40,P=0.021 9).ChIP suggested that ETS1 could specifically bind to FBXO45 promoter sequence to regulate its expression,confirming that ETS1 was a potential transcription factor of FBXO45.After overexpression of ETS1 in HCCLM3 and Huh7 cells,the invasion and migration abilities of cells were significantly enhanced,and the expression of N-cadherin and Snail was up-regulated(P<0.01).In addition,in the case of ETS1 overexpression,FBXO45 knockdown significantly inhibited the invasion and migration(P<0.01).Conclusion ETS1 activates the transcription of FBXO45 and leads its high expression,which enhances the invasion and migration of HCC cells via EMT pathway and promotes the progression of hepatocellular carcinoma.

Objective To explore the effect of meditative training combined with positive psychological intervention on pain,fatigue and sleep disorders in gastric cancer patients undergoing postoperative chemotherapy.Methods A total of 120 patients who underwent postoperative chemotherapy for gastric cancer in our hospital from August 2021 to August 2022 were randomly divided into control group and combination group,with 60 cases in each group.Positive psychological intervention was applied in both groups,and the combination group additionally received meditative training.The scores of pain,fatigue and sleep disorders,psychological distress,self-care ability and quality of life were compared between the two groups.Results After intervention,the scores of pain,fatigue,sleep disorders,physical quality,emotion,reality,family and spiritual/religious beliefs were significantly decreased in both groups,and the scores in the combined group were lower than those in the control group(all P<0.05).After intervention,the scores of self-concept,responsibility,nursing skills,health cognition,psychology,body,society,symptom and side effects,and specificity were significantly increased in both groups,and the scores in the combined group were higher than those in the control group(all P<0.05).Conclusion The meditation training combined with positive psychological intervention can significantly improve the scores of pain,fatigue and sleep disorders,psychological distress,self-care ability and quality of life in gastric cancer patients undergoing postoperative chemotherapy.

Objective: To explore the correlation between different nutritional status and depressive symptoms among adolescents, so as to provide a theoretical basis for targeted improvement of nutritional status and depressive symptoms in adolescents. Methods: A total of 8 102 adolescents aged 12-17 years in Shanghai, Urumqi, Changsha and Kunming were selected by random cluster sampling. Depressive symptoms were assessed by the Center for Epidemiologic Studies Depression Scale(CES-D). Height and weight were measured. Kruskal Wallis H test, Chi square test and ordinal Logistic regression were used to analyze the relationship between nutritional status and depressive symptoms in adolescents. Results: The overall detection rate of depressive symptoms in adolescents was 25.6%, with girls (30.1%) higher than that of boys (21.1%) ( χ 2=87.60, P <0.01). There were statistically significant differences in the scores of depressive symptoms among girls with different nutritional status ( Z =8.34, P <0.05). The detectable rate of depressive symptoms increased with BMI among girls( χ 2 trend =6.04, P <0.05). After controlling for confounding factors, ordinal Logistic regression showed that the obese girls had higher risks in depressive symptoms detection compared with normal weight girls ( OR=1.45, 95%CI=1.10-1.91, P <0.05). Conclusion The nutritional status of girls is better than boys, but the prevalence of depressive symptoms is higher than boys. The risk of depressive symptoms in girls increases with BMI.

Objective: To explore the relationship between adolescents physical fitness and depressive symptoms, and to provide reference for the early prevention and intervention of depressive symptoms and improvement of physical fitness in Chinese adolescents. Methods: From September to December 2021, a total of 8 102 adolescents were selected by random cluster sampling method in Shanghai, Urumqi, Changsha and Kunming. The Center for Epidemiologic Studies Depression Scale(CES-D) was used to investigate the depressive symptoms, and completed grip strength, standing long jump, 50 m running, modified sitting forward flexion, 20 s repeated traverse, 30 s sit ups, 20 m round trip running (20 m SRT) test. χ 2 test, Goodman Kruskal Gamma and Logistic regression analysis were used to analyze the relationship between physical fitness index(PFI) and depressive symptoms. Results: The overall detection rate of depressive symptoms in adolescents with high level PFI was 23.4%, and the detection rate of low level adolescents was 26.3%, with a statistically significant difference ( χ 2=6.73, P =0.01). There was a significant positive correlation between PFI and depressive symptoms in the high school group ( G=0.09, P <0.05) and the boy group ( G=0.12, P < 0.05 ), and there was no significant association between PFI and depressive symptoms in the junior high school group and the girl group ( P >0.05). After adjusting for gender and age in the Logistic regression model, compared with those with high PFI, the risk of depressive symptoms in those with low PFI was 1.18 times (95% CI =1.05-1.33). Conclusion There is a correlation between physical fitness and depressive symptoms in adolescents. Adolescents with low PFI are at higher risk of developing depressive symptoms than those with high PFI.

Hepatolithiasis is a common biliary tract disease in China and other Asian countries.It has insidious onset,recurrent disease,and may lead to biliary cirrhosis or even cancer in the late stage without inter-vention.At present,surgery is considered to be the best choice for treatment.In the 21st century of minimally inva-sive surgery,traditional procedures such as partial hepatectomy,choledochotomy,cholangioenterostomy and liver transplantation can be performed with the assistance of laparoscopy and da Vinci robots,and emerging endoscopic techniques such as endoscopic retrograde cholangiopancreatography(ERCP)and percutaneous transhepatic cho-ledochoscopic lithotripsy(PTCSL)have also been developed,bringing better treatment for patients with hepatoli-thiasis.As treatment options are becoming more varied,there are also some clinical problems that need to be addressed.In this article,we would like to briefly review the current surgical treatment modalities in order to provide a theoretical basis for optimizing the treatment modalities.

OBJECTIVE: To carry out genetic and metabolite analysis for an infant with cerebral creatine deficiency syndrome type 2 (CCDS2). METHODS: Clinical data of the child was collected. Whole-exome sequencing was carried out to identify potential variants by next generation sequencing. Candidate variants were confirmed by Sanger sequencing. Metabolites were determined by tandem mass spectrometry and magnetic resonance spectroscopy. Treatment was carried out following the diagnosis and genetic counseling for the affected family. RESULTS: Two novel heterozygous variants (c.289delC and c.392-1G>C) of the GAMT gene were identified in the proband, which were respectively inherited from her father and mother. In silico analysis suggested both variants to be pathogenic. Creatine (Cr) level of the child was very low, and cerebral guanidinoacetate (GAA) level was slightly increased. But both had recovered to normal in two weeks, and cerebral Cr level was significantly improved after two months. Intellectual and motor development of the child were significantly improved. CONCLUSION The child was diagnosed with CCDS type 2, for which pathogenic variants of the GAMT gene may be accountable. Treatment has attained a satisfactory effect for the patient.

Objective To analyze the risk factors of malignant glaucoma for primary angle-closure glaucoma(PACG) patients after surgery.Methods Clinical data of elderly patients with PACG who had received surgical treatment at our hospital between 2013 and 2016 were retrospectively analyzed.Patients were divided into two groups according to whether they suffered (Group A) or not (Group B) from malignant glaucoma after surgery.Results A total of 238 patients (315 eyes) were retrospectively analyzed: 17 cases (22 eyes) in Group A and 221 cases (293 eyes)in Group B.The index of axial length, chamber depth and crystal thickness was lower in Group A than in Group B,and the difference was statistically significant(P<0.05).Univariate analysis showed that age under 50, continuous high intraocular pressure, axial length below 22 mm, chamber depth below 2 mm, crystal thickness below 4.5 mm, completely closed anterior chamber angle and chronic angle-closure type were the possible risk factors for malignant glaucoma after surgery (P<0.05).The logistic regression analysis showed that age under 50 and axial length below 22 mm were independent risk factors for malignant glaucoma for PACG patients after surgery.Conclusion PACG patients,especially those who are young or with short axial length,are more vulnerable to malignant glaucoma.

Many studies have shown that high myopia is strongly hnked with glaucoma.Besides,due to its own characteristics of longer axial length,deeper anterior chamber depth and wider chamber angle width,high myopia is often more likely to develop a complication of primary open-angle glaucoma.However,the early fundus changes induced by glaucoma might be concealed by the fundus changes induced by high degree myopia because the latter itself could also induce a series of fundus changes.As a consequence,a deep understanding of the clinical features and diagnosis of high myopia with primary open-angle glaucoma is particularly essential in making early diagnosis as well as reducing missed diagnosis and misdiagnosis.This article summarizes the clinical features of high myopia with primary open-angle glaucoma to enhance understanding of such diseases and provide a basis for the early diagnosis of the diseases.
