Idiopathic pulmonary fibrosis （IPF） is a chronic and fibrotic lethal interstitial lung disease with poor prognosis. It is mainly treated by organ transplantation and administration of chemical drugs， which have poor efficacy and induce side effects， failing to meet the clinical needs. Therefore， it is urgent to develop more safe and effective drugs to treat IPF. Traditional Chinese medicine （TCM） has garnered increasing attention in recent years in the treatment of IPF due to its unique advantages. Increasing studies have shown that TCM has remarkable therapeutic effects on IPF and thus demonstrate broad application prospects. Modern medical research shows that the pathogenesis of IPF can be discussed from inflammation （macrophage polarization）， oxidative stress， epithelial-mesenchymal transition （EMT）， autophagy inhibition and other related signaling pathways， while few studies systematically explain the relationship between the signaling pathways and TCM theory. According to the theory of TCM， lung collateral obstruction is the basic pathogenesis of IPF. Therefore， according to the principle of dredging and replenishing lung collaterals， IPF can be treated with the methods of reinforcing healthy qi and eliminating pathogen， replenishing qi and activating blood， and detoxifying and dredging collaterals， which demonstrate definite curative effect and can effectively relieve clinical symptoms， restore the lung function and blood oxygen partial pressure， improve the quality of life of patients， and reduce adverse reactions. Experimental studies have found that dredging and replenishing lung collaterals have significant effects on IPF inflammation （macrophage polarization）， oxidative stress， EMT， autophagy inhibition and other signaling pathways. Therefore， from the perspective of impediment， this article reviews pathogenesis of IPF， the research progress in TCM treatment of IPF， and the treatment of IPF from active components， single herbs， and compound prescriptions of TCM， with the aim of revealing the scientific connotation of the treatment of IPF from impediment and providing a new theoretical basis for enriching the TCM methods of treating IPF.

AIM:To investigate the value of optical coherence tomography angiography(OCTA)indicators in the diagnosis of diabetic retinopathy(DR), and to provide patients with diabetic nephropathy(DN)with more sensitive OCTA screening indicators to detect concurrent DR at an early stage.METHODS: A total of 200 patients who treated in the ophthalmology department of the Seventh Affiliated Hospital, Sun Yat-sen University from 2022 to 2023 were included, including 95 first-diagnosed DR patients and 105 patients without DR, and all patients underwent OCTA examination and a collection of demographics and renal function parameters. After a quality check, automated measurements of the foveal avascular zone area, vessel density(VD), and perfusion density(PD)of both 3 mm×3 mm and 6 mm×6 mm windows were obtained.RESULTS: Using random forest and multivariate Logistic regression methods, we developed a diagnostic model for DR based on 12 variables(age, FBG, SBP, DBP, HbA1c, ALT, ALP, urea/Scr, DM duration, HUA, DN, and CMT). Adding specific OCTA parameters enhanced the efficacy of the existing diagnostic model for DR(outer vessel density in 6 mm×6 mm window, AUC=0.837 vs 0.819, P=0.03). In the study of DN patients, the parameters in the 6 mm×6 mm window improved the diagnostic efficacy of DR(inner VD; outer VD; full VD; outer PD; full PD).CONCLUSION:The outer VD in the 6 mm×6 mm window can enhance the efficacy of the traditional DR diagnostic model. Meanwhile, compared with the 3 mm×3 mm window, the microvascular parameters in the 6 mm× 6 mm window focusing on DN patients can be more sensitive to diagnosing the occurrence of DR.

Objective: To explore the feasibility of synthetic magnetic resonance imaging (syMRI) combined with clinicopathological characteristics for the pre-treatment prediction of chemoradiotherapy (CRT) response in advanced nasopharyngeal carcinoma (ANPC). Materials and Methods: Patients with ANPC treated with CRT between September 2020 and June 2022 were retrospectively enrolled and categorized into response group (RG, n = 95) and non RGs (NRG, n = 32) based on the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. The quantitative parameters from pre-treatment syMRI (longitudinal [T1] and transverse [T2] relaxation times and proton density [PD]), diffusion-weighted imaging (apparent diffusion coefficient [ADC]), and clinicopathological characteristics were compared between RG and NRG. Logistic regression analysis was applied to identify parameters independently associated with CRT response and to construct a multivariable model. The areas under the receiveroperating characteristic curve (AUC) for various diagnostic approaches were compared using the DeLong test. Results: The T1, T2, and PD values in the NRG were significantly lower than those in the RG (all P < 0.05), whereas no significant difference was observed in the ADC values between these two groups. Clinicopathological characteristics (Epstein–Barr virus [EBV]-DNA level, lymph node extranodal extension, clinical stage, and Ki-67 expression) exhibited significant differences between the two groups. Logistic regression analysis showed that T1, PD, EBV-DNA level, clinical stage, and Ki-67 expression had significant independent relationships with CRT response (all P < 0.05). The multivariable model incorporating these five variables yielded AUC, sensitivity, and specificity values of 0.974, 93.8% (30/32), and 91.6% (87/95), respectively. Conclusion SyMRI may be used for the pretreatment prediction of CRT response in ANPC. The multivariable model incorporating syMRI quantitative parameters and clinicopathological characteristics, which were independently associated with CRT response, may be a new tool for the pretreatment prediction of CRT response.

Objective:To explore the effects of Baduanjin and brisk walking on the sleep quality among fe-male college students.Methods:Ninety female college students with poor sleep quality[Pittsburgh Sleep Quality Index(PSQI)≥ 8]were recruited randomly assigned to Baduanjin,brisk walking,and control groups,with 30 par-ticipants in each.The Baduanjin and brisk walking groups participated in 10-week intervention(five 45-minute ses-sions per week),while the control group did not receive any intervention.Baseline and post-intervention assessments were conducted using the PSQI,a lung capacity test,echocardiography,and the Fatigue Scale(FS-14).Results:Af-ter 10 weeks,participants in both the Baduanjin and brisk walking groups got significantly lower PSQI and FS-14 total scores compared to baseline(Ps＜0.001).Cardiopulmonary function indicators,including stroke volume(SV),forced expiratory volume in one second(FEV1.0),the vital capacity-to-body mass index(VC/W),and maximum voluntary ventilation per minute(MVV),also significantly improved(Ps＜0.001).Furthermore,the Baduanjin group had significantly lower PSQI and FS-14 scores than both the brisk walking and control groups(P＜0.001),along with superior improvements in cardiopulmonary function(P＜0.001).Conclusion:This study in-dicates that Baduanjin is particularly effective in improving sleep quality,cardiopulmonary function,and reducing fatigue among female college students,showing advantages over brisk walking.

Objective:To investigate the effect of circular RNA (circRNA)_005987 on contrast-associated acute kidney injury (CA-AKI) and its mechanism, and provide new ideas for the prevention and treatment of CA-AKI.Methods:CA-AKI rat models and HK-2 cell injury models were established using iopromide, and CA-AKI-related circRNA_005987 was screened based on circRNA expression chip and real-time quantitative PCR (RT-qPCR). Knockdown and overexpression of circRNA_005987 were performed in HK-2 cell model, respectively. Cell counting kit-8 (CCK-8) and Edu staining assays were used to evaluate cell proliferation. Western blotting was used to detect the protein expression of autophagy-related protein microtubule-associated protein 1 light chain 3B (LC3B), P62, beclin-1 and autophagy-related gene 14 (ATG14). Immunofluorescence staining was used to detect protein expression of LC3B. Electron microscope was used to observe the autophagosome formation. Autophagy activator rapamycin and autophagy inhibitor 3-methyladenine were used for in vitro rescue experiments to observe the changes of the above indicators. Mechanistically, bioinformatics analysis was applied to analyze the binding site among circRNA_005987, miR-129-5p and ATG14, and dual luciferase reporter assay was used to verify their interactions. CircRNA_005987 was knocked down and overexpressed in HK-2 cell model, and RT-qPCR was used to detect the expression of miR-129-5p. HK-2 cells were treated with miR-129-5p inhibitor and mimic, Western blotting was used to detect the protein expression of ATG14, and CCK8 and Edu staining assays were used to evaluate cell proliferation. Results:CircRNA_005987 expression was up-regulated in vitro and vivo CA-AKI models (both P<0.05). Overexpression of circRNA_005987 inhibited cell proliferation and promoted cell autophagy, while knockdown of circRNA_005987 had opposite effects (all P<0.05). In vitro rescue experiments confirmed that circRNA_005987 inhibited cell proliferation by activating autophagy ( P<0.05). The dual luciferase reporter assay suggested that there was an interaction between circRNA_005987, miR-129-5p and ATG14. Knockdown of circRNA_005987 increased miR-129-5p expression, while overexpression of circRNA_005987 inhibited miR-129-5p expression (both P<0.05). Knockdown of miR-129-5p inhibited cell proliferation, while overexpression of miR-129-5p reversed the effect (both P<0.05). Conclusion:CircRNA_005987 promotes CA-AKI through activating autophagy via sponging miR-129-5p, suggesting that circRNA_005987 plays an important role in the pathological process of CA-AKI.

Objective:To explore the diagnostic value of transcranial magnetic stimulation (TMS), transsacral magnetic root stimulation combined with sacral reflexes, external anal sphincter electromyography and pudendal nerve somatosensory evoked potentials in the assessment of neurogenic lower urinary tract dysfunction (NLUTD).Methods:Twenty-one NLUTD patients (1 with a supra-pontine lesion, 5 with a spinal cord injury, 5 with a cauda equina injury, and 10 with pelvic floor disorders) were enrolled. Needle electromyography (EMG) was used to record TMS-induced and transsacral magnetic stimulation-induced motor evoked potentials (tc-MEPs and ts-MEPs, respectively) related to the external anal sphincter (EAS). The dorsal nerve of the penis or clitoris was stimulated electrically to record the latency of the sacral reflex related to the EAS. Central motor conduction time (CMCT) and the tc/ts-MEP latency ratio were calculated to distinguish central from peripheral lesions.Results:In the one patient with a supra-pontine lesion, although the tc-MEP and ts-MEP latencies were within normal limits, the CMCT was prolonged (28.2ms) and the tc/ts-MEP ratio was large (7.4). Among the five patients with a spinal cord injury, one exhibited prolonged tc-MEP latency (50.6ms) and CMCT (47.8ms), along with a large tc/ts-MEP ratio (18.1). In the five patients with cauda equina injury and the ten with NLUTD secondary to pelvic floor disorders, CMCT was within the normal range [averaging (22.9±4.9ms) and (24.2±3.5ms), respectively], but the ts-MEP latency was prolonged [(7.1±2.1ms) and (8.6±3.7ms), respectively], and the tc/ts-MEP ratio was small [(4.4±0.9) and (4.3±1.5), respectively]. The tc/ts-MEP ratio demonstrated the best rate of abnormality detection (93.8%), with an area under the curve of 0.99, indicating good sensitivity.Conclusions:The tc/ts-MEP ratio can be useful for distinguishing central and peripheral lesions. A markedly increased tc/ts-MEP ratio may suggest central nervous system injury, whereas a decreased ratio may indicate peripheral nervous system injury.

Objective:To investigate the distribution of health needs and healthcare workforce demands among potential service users in community health service institurions (CHSIs) and establish a comprehensive health needs profile for targeted service development.Methods:This is a cross-sectional study. A questionnaire survey (55 items for adults and 39 items for minors) was conducted among 564 residents aged 3-65 in Dapuqiao Subdistrict, Shanghai from March to May 2024. A health sketch model was developed, encompassing five dimensions (intake, basal metabolism, consumption, influencing factors, and somatosensory perception). Health issues were mapped to standardized healthcare services, and annual standardized workloads (SW) were calculated to quantify human resource demands. Results:Among 534 valid responses (94.68% response rate), 355 from the adults and 179 from minors, the top health issues for adults were irregular diet, nutritional imbalance, obesity, somatic fatigue, and disordered eating; for minors, they were nutritional imbalance, medication overuse, insufficient physical activity, picky eating, and anorexia. The total annual SW required to address these needs was 3 906 807.93. Among them, the total SW for each age group was as follows: the total annual SW demand for children aged between 3 and 5 years old was 24 108.90, for children aged between 6 and 11 years old was 141 355.70, for adolescents aged between 12 and 17 years old was 29 813.74, 223 475.50 for 18-24 year olds, 476 426.53 for 25-34 year olds, 1 221 105.84 for 35-44 year olds, 812 200.22 for 45-54 year olds; and 978 321.50 for 55-65 year olds. Workforce allocation analysis revealed a total demand for 139.84 standardized personnel, with rehabilitation therapists (38.16), general practitioners (35.69), and nurses (27.34) being the top three required roles.Conclusions:Health needs and workforce demands vary significantly across age groups. This study provides a data-driven framework for optimizing community health services through stratified health needs profiling and precision resource allocation. Future strategies should prioritize tailored interventions and workforce planning to bridge service gaps and enhance health outcomes.

Objective To investigate the impact of parental career deficit on college students' career decision-making difficulties and analyze the mediating role of psychological capital and career exploration in this relationship.Methods The Perceived Parental Career-Related Behavior Scale,Career Decision-making Difficulty Scale,Psychological Capital Questionnaire,and Career Exploration Inventory were administered to 356 college students.Results Scores of parental career deficit,psychological capital,career exploration,and career decision-making difficulties were 1.84±0.64,4.55±0.77,3.17±0.67,and 5.19±1.12,respectively.Parental career deficit was negatively correlated with psychological capital and career exploration(r=-0.283,r=-0.134,both P＜0.05),but positively correlated with career decision-making difficulties(r=0.373,P＜0.01).The college students'psychological capital was positively correlated with their career exploration(r=0.589,P＜0.01),but negatively correlated with career decision-making difficulties(r=-0.457,P＜0.01).Career exploration was negatively correlated with career decision-making difficulties(r=-0.409,P＜0.01).Bootstrap mediation effect analysis revealed that psychological capital and career exploration acted as chain mediators in the relationship between lack of parental career support and career decision-making difficulties.The value of the chain-mediated effect was 0.068,accounting for 10.38％ of the total effect.Conclusion Parental career deficit not only directly impacts college students' career decision-making difficulties but also indirectly influences these difficulties through their effects on psychological capital and career exploration.

Objective:To investigate the influence of four preoperative CT image characteristics on the outcome of thoracoscopic surgery for chronic tuberculous empyema.Methods:This is a retrospective cohort study. Two hundred and eleven patients of tuberculous empyema who underwent video-assisted thoracic surgery(VATS) decortication at the First Department of Surgery , Wuhan Pulmonary Hospital from June 2020 to June 2023 were retrospectively analyzed. There were 162 male cases and 49 female cases, with an age ( M (IQR)) of 33 (27) years (range: 8 to 76 years). Patients were divided into two groups according to whether low-density lines, mass-patchy density, pleural fusion were observed, and the lesion size. Compare the clinical indicators of two groups of cases. Using the rapeutic efficacy as the dependent variable and four CT features as covariates, cases with cure or improve were included in Logistic regression analysis to calculate OR (95% CI) values. Results:Preoperative chest CT images showed that 127 cases (60.2%) had low-density lines, 102 cases (48.3%) had mass-patchy density, and 88 cases (47.7%) had pleural fusion. The lesions spanned 2 to 11 intercostal spaces, with a median of 7 intercostal spaces. The lesion size was divided into two groups according to <7 intercostal spaces and ≥7 intercostal spaces, with 101 cases (47.9%) and 110 cases (52.1%), respectively. In the intra-group comparison, there were no difference in age, lesion location and pulmonary tuberculosis. In the comparison of gender, except that the proportion of female patients in the group with lesion size <7 intercostal spaces ( χ2=6.064, P=0.010) was higher than ≥7 intercostal spaces, there were no significant difference between other groups. In low-density lines group, there was no difference in the incidence of anemia and hypoproteinemia between the two groups. Compared with the non low-density line group, patients with low-density line group exhibited fewer cases of abnormal elevation in ESR and CRP was lower(all P<0.01), the period of preoperative treatment ( U=7 281.00, P<0.01) was longer than the non low-density line group, while the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours, postoperative drainage duration, lung re-expansion duration, and therapeutic efficacy were all better than the non low-density line group(all P<0.05). In the comparison between the mass-patchy density group, there were fewer cases of anemia, hypoproteinemia, abnormal elevation of ESR and CRP in the without mass-patchy density group(all P<0.05), and the period of preoperative treatmentwas shorter ( U=4 581.50, P=0.026), and the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours, postoperative drainage duration, lung re-expansion duration and therapeutic effect were better too(all P<0.05). In the grouping comparison of pleural fusion, there were no difference in cases of anemia, hypoproteinemia, abnormal elevation of ESR and CRP, and the period of preoperative treatment between the two groups; the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours, postoperative drainage duration, lung re-expansion duration, and therapeutic efficacy of the group without pleural fusion were better than the group with pleural fusion(all P<0.05). The group with <7 intercostal spaces had fewer cases of anemia, hypoproteinemia, abnormal elevation of ESR and CRP (all P<0.05), the period of preoperative treatment was longer ( U=4 295.00, P=0.004), the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours,postoperative drainage duration, lung re-expansion duration and complications were less (all P<0.05), the therapeutic efficacy was better than the group with ≥7 intercostal spaces ( χ2=27.912, P<0.01). The Logistic regression analysis of cured and improved cases showed that mass-patchy density and lesion size were independent risk factors affecting the therapeutic efficacy (all P<0.05). Conclusions:For patients with CT images showing mass-patchy density, pleural fusion, and a large lesion size, the difficulty and risk of surgery may be relatively high.The preoperative CT images can provide objective reference for clinical preoperative evaluation.
