ObjectiveTo investigate the potential mechanism of action of the Qufeng Tongqiao Cough-relieving Decoction （祛风通窍止咳方， QTCD） in the treatment of upper airway cough syndrome （UACS）. MethodsTwenty-four guinea pigs were randomly divided into blank group， model group， traditional Chinese medicine （TCM） group， and inhibitor group， with six guinea pigs in each group. Except for the blank group， guinea pigs were sensitized with ovalbumin and aluminum hydroxide via intraperitoneal injection， followed by ovalbumin nasal drops combined with smoke exposure to establish the UACS model. After modeling， the TCM group was administered QTCD 0.9 g/（100 g·d） by gavage， the inhibitor group received the transient receptor potential vanilloid receptor 4 （TRPV4） inhibitor GSK2193874 1 mmol/L， 5 min by nebulisation， and the blank group and model group were given 2 ml/（100 g·d） normal saline by gavage once daily. After 7 days of treatment， a cough provocation test was performed using 0.4 mol/L citric acid. The levels of IgE in serum and inflammatory cytokines， including interleukin-6 （IL-6）， interleukin-8 （IL-8） in serum， bronchoalveolar lavage fluid （BALF）， and nasal lavage fluid （NLF） were detected by enzyme-linked immunosorbent assay （ELISA）. Histopathological changes in lung and nasal mucosal tissues were observed by hematoxylin-eosin （HE） staining. Immunohistochemistry was used to detect the protein levels of TRPV4， substance P （SP）， and calcitonin gene-related peptide （CGRP） in lung and nasal mucosal tissues. Real-time polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of TRPV4， SP， and CGRP in lung tissues. ResultsHE staining showed significant structural damage and infiltration of inflammatory cells in the lung and nasal mucosal tissues in the model group， while the TCM group and inhibitor group showed improved pathological changes. Compared with the blank group， the model group showed increased cough frequency， serum IgE level， and IL-6 and IL-8 levels in serum， BALF， and NLF. The protein levels of TRPV4， SP， and CGRP in lung and nasal mucosal tissues and their mRNA expression were elevated （P＜0.05 or P＜0.01）. Compared with the model group， the TCM group and inhibitor group showed reduced cough frequency， serum IgE level， and TRPV4 and SP mRNA expression in lung tissues. The TCM group showed reduced IL-6 and IL-8 levels in serum， BALF， and NLF， and reduced TRPV4 and CGRP protein levels in lung and nasal mucosal tissues. The inhibitor group showed reduced IL-6 and IL-8 levels in serum， BALF， and NLF， reduced IL-6 in BALF， reduced IL-8 in NLF， and decreased TRPV4， SP， and CGRP protein levels in lung tissues and SP and CGRP protein levels in nasal mucosal tissues （P＜0.05 or P＜0.01）. Compared with the TCM group， the inhibitor group had increased serum IgE， IL-6， and IL-8 levels， increased IL-6 level in BALF， and increased IL-8 levle in NLF， but decreased SP protein level in lung tissues and increased TRPV4 and SP mRNA expression in lung tissues （P＜0.01）. ConclusionQTCD effectively reduces cough frequency in the UACS guinea pig model. Its mechanism may involve inhibiting the activation of the TRPV4 pathway， improving airway neurogenic inflammation， alleviating inflammatory responses， and reducing cough hypersensitivity.

Objective: To investigate the status quo and associated factors of drinking water knowledge, attitude and behavior among primary school students in rural areas, so as to provide evidence for health behavioral intervention of drinking water in primary school. Methods: Twentythree primary schools in rural area from Hebei, Henan, Shandong and Shanxi provinces were selected by using purposive sampling method from March 1 to April 27 in 2023. Selfdesigned questionnaires regarding knowledge, attitude and behavior of drinking water were distributed to all students in grade 3-6, and 2 173 valid questionnaires were obtained. Multivariate Logistic regression was used to analyze the influencing factors of drinking water knowledge, attitude and behavior of primary school students. Results: The attainment rates of drinking water knowledge, attitude and behavior level were 20.02%, 26.65%, and 31.20%, respectively, among primary school students. The median of daily water intake was 1 000 mL, and the average daily water intake was (1 172.99±771.89)mL. In addition, 66.31% of students water intake reached the minimum standard of 800 mL recommended. The results of multiple Logistic regression indicated that drinking water accessibility in school, health education of drinking water, and individual selfcontrol ability were positively correlated with the knowledge (OR=1.31, 1.57, 1.58), attitude (OR=2.07, 1.65, 1.73), behavior (OR=1.40, 1.49, 1.91) of drinking water and daily water intake (OR=1.41, 1.38, 1.20) (P<0.05). Conclusions Primary school students in rural areas are generally lack of appropriate health awareness on drinking water including knowledge, attitude and behavior. Schools should take targeted measures to focus on the cultivation of students selfcontrol ability, so as to improve students knowledge and attitudes of drinking water, and furthermore help students shape their healthy behaviors of drinking water.

Objective:To observe the effects of transcranial direct current stimulation (tDCS) on functional connectivity (FC) in language-related brain regions of patients with picture-naming dysfunction after cerebral infarction by using resting state functional magnetic resonance imaging(rs-fMRI).Methods:Twenty-eight patients with post-infarction picture-naming dysfunction were divided into an acute stage group( n=16) and a recovery stage group( n=12) according to the course of the disease, and 18 middle-aged and elderly volunteers were recruited as the normal control group.The anodic tDCS was applied on the posterior perisylvian region(PPR) of the left sylvian of the patients, 5 days a week for 2 weeks.Before and after the 2 weeks′ treatment, the rs-fMRI and Psycholinguistic Assessment of Chinese Aphasia (PACA)-picture-naming subscale were performed, and FC changes in language-related brain areas were observed. Results:After treatment, the PACA scores of patients in both acute and recovery stage groups were significantly improved after treatment( P<0.05). Compared with normal subjects, FC in multiple brain regions and particularly the Wernicke area was reduced in both cerebral hemispheres among the patient group. It was more severe in the dominant hemisphere.After the tDCS treatment, FC in both frontotemporal lobes and in the Wernicke area was significantly enhanced in both the acute and recovery groups. Further comparison showed that in the acute group FC in both temporo-occipital lobes was significantly enhanced after treatment. In the recovery group, the enhanced FC in the left temporal lobe before the treatment was significantly reduced after treatment. Conclusion:The fMRI technique can evaluate changes in brain connectivity in aphasia patients with picture-naming dysfunction after cerebral infarction accurately and non-invasively.tDCS may improve picture-naming function of stroke patients by enhancing the FC in bilateral language-related brain areas(concentrated in frontotemporal lobes) and Wernicke area.

Objective:To observe the effects of Sanjia Powder on myocardial fibrosis in diabetic cardiomyopathy (DCM) model rats; To elaborate its mechanism.Methods:A DCM rat model was constructed using STZ single intraperitoneal injection combined with high-sugar and high-fat feeding. The model rats were divided into model group, TCM group, Western medicine group, miR-21 inhibition group, and miR-21 inhibition control group using a random number table method, with 10 rats in each group; another 10 SD rats were set as normal group. TCM group was orally administered with Sanjia Powder water decoction at a dose of 6.2 g/kg, and the Western medicine group was administered metformin 250 mg/kg + enalapril 45 mg/kg by gavage. miR-21 inhibition group, miR-21 inhibition control group, normal group, and model group were given the same volume of distilled water by gavage, once a day, for 4 weeks; at the same time, the normal group, the model group, TCM group, and the Western medicine group were injected with the same amount of normal saline in the tail vein. The miR-21 inhibition group received tail vein injection of miR-21 inhibitor at a dose of 20 mg/kg, and the miR-21 inhibition control group received tail vein injection of miR-21 inhibitor NC at a dose of 20 mg/kg, twice a week, for 4 weeks. The morphological changes of myocardial tissue were observed using HE; the expression of Collagen-Ⅰ in myocardial tissue was detected using Western Blot; the expressions of endothelial cell marker CD31 and stromal cell marker FSP1 in myocardial tissue were detected using immunofluorescence method.Results:Compared with the model group, the pathological morphology of myocardial tissue improved in the TCM group, Western medicine group, and miR-21 inhibition group, while the expressions of Collagen-Ⅰ and FSP1 decreased ( P<0.01) and the expression of CD31 increased ( P<0.01); there was no statistically significant difference in the expressions of Collagen-Ⅰ, CD31, and FSP1 between the TCM group and the miR-21 inhibition group ( P>0.05). Conclusion:Sanjia Powder can improve myocardial fibrosis in rats with diabetic cardiomyopathy, and its mechanism may be related to the up-regulation of CD31 expression and down-regulation of FSP1 expression, thereby inhibiting endothelial mesenchymal transition, and may also be related to the inhibition of miR-21 expression.
