With the increasing utilization of cancer therapy, the incidence of lung injury associated with these treatments continues to rise. The recognition of pulmonary toxicity related to cancer therapy has become increasingly critical, for which interstitial lung disease (ILD) is a common cause of mortality. Cancer therapy-related ILD (CT-ILD) can result from a variety of treatments including chemotherapy, targeted therapy, immune checkpoint inhibitors, antibody-drug conjugates, and radiotherapy. CT-ILD may progress rapidly and even be life-threatening; therefore, prompt diagnosis and timely treatment are crucial for effective management. This review aims to provide valuable information on the risk factors associated with CT-ILD; elucidate its underlying mechanisms; discuss its clinical features, imaging, and histological manifestations; and emphasize the clinical-related views of its diagnosis. In addition, this review provides an overview of grading, typing, and staging treatment strategies used for the management of CT-ILD.

Objective: To explore differences in the factors influencing parents and teachers assessments of preschool children s mental health using the Strengths and Difficulties Questionnaire (SDQ), so as to provide reference for promoting children s mental health. Methods: A retrospective analysis was conducted on the SDQ survey data of 14 763 middle and senior kindergarten children in Nanshan District, Shenzhen, from March to June 2023. Chi square χ 2 tests were used to analyze differences in mental health assessments between parents and teachers. Multivariate Logistic regression was employed to examine the factors influencing parental assessments, and Kappa coefficients were used to evaluate the consistency between parent and teacher evaluations. Results: The positive rate of mental health problems reported by parents (7.2%) was significantly higher than that reported by teachers (6.2%) ( χ 2=254.27, P <0.01). Gender differences revealed that parents reported a lower positive rate for boys (7.9%) compared to teachers (8.5%), whereas for girls, the parental positive rate (6.4%) was higher than that reported by teachers (3.8%) ( χ 2=163.59, 81.26, all P <0.01). Age related differences showed that parental positive rates for 4, 5, and 6 year olds (8.5%, 7.4%, 5.8%) were consistently higher than teachers assessments (6.3%, 6.7%, 5.4%) ( χ 2=41.23, 157.53, 63.67, all P <0.05). Univariate analysis of parental assessments indicated higher positive rates among boys (7.9%), 4 year olds (8.5%), mothers aged 20-35 ( 6.6 %), mothers with high school education or below (9.8%), fathers aged 23-40 (6.4%), fathers with high school education or below (10.3%), and children exposed to secondhand smoke (7.9%) ( χ 2=23.56-235.24, all P <0.01). Multivariate Logistic regression identified lower parental education levels and exposure to secondhand smoke as significant risk factors for abnormal SDQ assessments by parents ( χ 2=2.05, 1.62, 3.15, all P <0.05). The Kappa coefficients for parent-teacher agreement across SDQ subscales and total difficulties ranged from 0.04 to 0.12 (all P <0.01). Conclusions Parental education level and exposure to secondhand smoke are significant factors influencing preschool children s mental health. Differences exist between parental and teacher assessments of children s mental health, and incorporating teacher evaluations can provide a more comprehensive understanding of preschoolers psychological well being.

Objective::To investigate the correlation between maternal serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and gestational duration in pregnant women with pulmonary hypertension (PH).Methods::The study included pregnant individuals with PH stemming from mitral valve stenosis and mitral valve regurgitation (post-capillary PH) or pulmonary arterial hypertension (pre-capillary PH) who were admitted to Guangdong Provincial People’s Hospital between January 1, 2014 and December 31, 2020. In this retrospective cohort study, maternal serum NT-proBNP levels during pregnancy, along with other clinical data, were obtained from structured electronic medical records. These data included gestational age at delivery, echocardiographic parameters, laboratory findings, gestational duration, delivery mode, and other relevant clinical variables. Univariate and multivariate regression analyses were conducted to assess the association between NT-proBNP levels and gestational duration. Adjustments were made for potential confounding factors, and curve fitting and threshold effect analysis were employed to identify tangent points. Furthermore, stratified analyses were performed based on tricuspid regurgitation velocity, maternal age, and parity.Results::A total of 64 patients with post-capillary PH and 74 patients with pre-capillary PH were included in this study. Among patients with post-capillary PH, the results of multivariate regression analysis indicated a significant association between maternal NT-proBNP levels and gestational duration (β = -0.03, 95% confidence interval (CI) -0.05 to 0.00, P = 0.02). The fitted curve demonstrated a negative correlation between maternal NT-proBNP levels and gestational duration, with a significant break point at 379.9 ng/L ( P < 0.05). In the post-capillary PH group, the stratified analysis revealed a regression coefficient of -0.05 (95% CI:-0.06 to -0.04, P = 0.001) in patients with a tricuspid regurgitation velocity >340 mm/s. For patients >35 years old, the regression coefficient was -0.03 (95% CI -0.06 to -0.01, P = 0.02). In multiparous women, the regression coefficient was -0.03 (95% CI-0.06 to 0.00, P = 0.03). Conclusion::In pregnant women with pulmonary hypertension, maternal NT-proBNP levels are associated with gestational duration, particularly with an increased risk of preterm labor.

PURPOSE: Extensive data support the influence of the upper airway on lower airway inflammation and pathophysiology in allergic disease. However, few studies have focused on allergic inflammation in the nose after an isolated lower airway allergen challenge, a situation that can exist clinically when human subjects breathe primarily through the mouth, as occurs when nasally congested. This study used a mouse model to investigate whether upper airway inflammation and hyperresponsiveness were induced by an isolated lower airway allergen challenge. METHODS: BALB/c mice were sensitized by systemic intraperitoneal injection of ovalbumin/saline and challenged with intratracheal ovalbumin/saline. Inflammation in the nose and lungs was assessed by cytology and histology of nasal tissues and bronchoalveolar lavage fluid (BALF), while nasal airway resistance and response were measured over 3 days post-challenge. RESULTS: Intratracheal application of an allergen in anaesthetized mice resulted in exclusive deposition in the lower airway. Compared to control animals, ovalbumin-sensitized mice after challenge showed bronchial hyperreactivity and increased IL-5 in the serum BALF, as well as eosinophil infiltration in the lungs. However, nasal histology of the ovalbumin-sensitized mice showed no increase in eosinophil infiltration. The nasal lavage fluid revealed no increase in eosinophils or IL-5, and the nasal airway resistance did not increase after challenge either. CONCLUSIONS: In a mouse allergy model, exclusive allergen challenge of the lower airway can elicit a pulmonary and systemic allergic response, but does not induce upper airway inflammatory or physiological responses.

OBJECTIVE: To investigate the protective effect of the decoction of tartary buckwheat flavonoids on focal cerebral is-chemia-reperfusion injury of rats. MEHTODS: Fifty male SD rats will be randomly divided into normal group, cerebral ischemia-reperfusion group (model group), high dose of tartary buckwheat flavonoids group, middle dose of tartary buckwheat flavonoids group and low dose of tartary buckwheat flavonoids group, each groups of 10 rats. A rat model of the right middle cerebral artery occlusion/reper-fusion(MCAO) was established by the filament method. After being operated, treatment-group rats will be administered 100,75 and 50 mg · kg-1 of the decoction of tartary buckwheat flavonoids three times a day for 7 consecutive days, after administrated for 7 d, rats in each group will undergo neurobehavioral tests. Expressions of cerebral inducible nitric oxide synthase (iNOS) and endothelial nitric oxide synthase (eNOS) were measured by SP immunohistochemistry. The optical density value (OD) was measured by imaging analysis, and the percentage of cells with iNOS and eNOS positive expression was analyzed under light microscope. RESULTS: Compared with ischemia-reperfusion group, neurological function score increased in the decoction of tartary buckwheat flavonoids groups. Treatment groups had lower expression level of iNOS but higher expression level of eNOS than those in the model groups (P < 0.01, P < 0.05). The number of neurons of Hippocampal CA1 was increased (P < 0.05). CONCLUSION: Tartary buckwheat flavonoids can improve neurological function and decrease the expression of iNOS and increase the expression of eNOS in cerebral ischemia-reperfusion rats, which may contribute to the protection of neural function.

OBJECTIVETo analyze the clinical value of dual-source CT (DSCT) in the diagnosis of coronary artery disease.

METHODSFifty-five patients with suspected coronary heart disease underwent both DSCT coronary angiography (DSCTCA) and selective coronary angiography (CAG) examination, and the diagnostic sensitivity, specificity and accuracy of the DSCTCA was evaluated.

RESULTSThe sensitivity, specificity, positive and negative predictive value, and accuracy of DSCT in the diagnosis of coronary heart disease were 97.7%, 72.6%, 93.5%, 88.9% and 92.7% by the number of patients, respectively; by calculating the coronary arteries, the sensitivity, specificity, positive and negative predictive value, accuracy were 94.9%, 95.8%, 92.5%, 97.1%, 95.5%, respectively. According to the lesion segment, these values were 88.2%, 96.9%, 90.5%, 96.1%, 94.7%, respectively. DSCTCA showed no significant difference from CAG for a diagnostic purpose, nor did their vessel sensitivity, specificity, positive and negative predictive value, and accuracy in different coronaries differ significantly.

CONCLUSIONDSCT has a diagnostic accuracy of coronary heart disease close to that CAG and can on some occasion serve as an alternative to CAG in the screening of coronary artery disease.

OBJECTIVETo investigate the correlation between vascular remodeling index (RI) and serum adiponectin, plasma monocyte chemoattractant protein-1 (MCP-1), endothelial function and evaluate the mechanism of coronary in-stent restenosis.

METHODSRI 6 months after percutaneous coronary intervention (PCI), serum adiponectin, plasma MCP-1 and flow-mediated dilation (FMD) before and 3 days,6 months after PCI were measured in 30 patients with and 30 without coronary in-stent restenosis.

RESULTSCompared with patients without restenosis and those with restenosis before PCI, the patients with coronary in-stent restenosis showed significantly increased plasma MCP-1 3 days and 6 months after PCI (P<0.05) and reduced RI 6 months after PCI, serum adiponectin and FMD 3 days and 6 months after PCI (P<0.05). RI was positively correlated to serum adiponectin and FMD and inversely to MCP-1.

CONCLUSIONThe occurrence of coronary in-stent restenosis is the result of the interrelations between multiple factors.
