Objective: To understand the unhealthy listening habits and related factors hearing on impairment among primary and middle school students in Jilin Province, so as to provide a scientific basis for the prevention of hearing impairment in children and adolescents. Methods: From September to November 2021, a stratified cluster random sampling method was employed to select 12 847 primary and middle school students in nine cities of Jilin Province who use headphones for more than 0.5 hours daily for a questionnaire survey. Data on unhealthy listening habits, lifestyle habits and hearing impairment were collected. The data were analyzed using the χ 2 test and Logistic regression. Results: Totally 1 702 students(13.25%) experienced hearing impairment within the last month. There were statistical differences between the sexes with the average daily headphone use, the times of using headphones ≥1 h every day for one week use in all environment or noisy environment ( χ 2=47.86, 57.60, 66.31, P <0.01). Logistic regression analysis results showed that factors related to the occurrence of hearing impairment among primary and secondary school students included:average daily headphone use of 1-2 h and more than 2 h ( OR=1.74, 95%CI =1.60-1.90; OR=1.73, 95%CI =1.59-1.90), times of using headphones ≥1 h every day for one week were 1-2 times and >2 times ( OR=1.71, 95%CI =1.59- 1.84 ; OR=1.83, 95%CI =1.71-1.97), the times of using headphones≥1 h every day for one week being 1-2 times and >2 times in noisy environment per week ( OR=1.48, 95%CI =1.40-1.56; OR=1.72, 95%CI =1.61-1.86), economic underdevelopment ( OR=1.85, 95%CI =1.76-1.96), boarding （OR=1.78, 95%CI =1.69-1.89), single parent family ( OR=1.72, 95%CI =1.60- 1.87 ), daily activity duration less than 1 h ( OR=1.71, 95%CI =1.63-1.81), sedentary behavior duration more than 6 h per day ( OR=1.88, 95%CI =1.79-1.98) ( P <0.05). Conclusions The behavior of ear protection among primary and middle school students in Jilin Province needs to be enhanced, focusing on students in economically underdeveloped areas, boarding schools and single parent families. It is necessary to guide primary and middle school students to improve their bad ear habits, increase outdoor activities and reduce the time of sitting.

ObjectiveTo evaluate the effects of Tongnaoyin on the blood-brain barrier status and neurological impairment in acute ischemic stroke （AIS） patients with the syndrome of phlegm-stasis blocking collaterals by dynamic contrast-enhanced magnetic resonance imaging （DCE-MRI）. MethodsA total of 63 patients diagnosed with AIS in the Jiangsu Province Hospital of Chinese Medicine from October 2022 to December 2023 were enrolled in this study. According to random number table method，the patients were assigned into a control group （32 cases） and an observation group （31 cases）. The control group received conventional Western medical treatment，and the observation group took 200 mL Tongnaoyin after meals，twice a day from day 2 of admission on the basis of the treatment in the control group. After 7 days of treatment，the patients were examined by DCE-MRI. The baseline data for two groups of patients before treatment were compared. The National Institute of Health Stroke Scale （NIHSS） score and modified Rankin Scale （mRS） score were recorded before treatment and after 90 days of treatment for both groups. The rKtrans，rKep，and rVe values were obtained from the region of interest （ROI） of the infarct zone/mirror area and compared between the two groups. ResultsThere was no significant difference in the NIHSS or mRS score between the two groups before treatment. After 90 days of treatment，the NIHSS and mRS scores declined in both groups，and the observation group had lower scores than the control group （P<0.05）. After treatment，the rKtrans and rVe in the observation group were lower than those in the control group （P<0.01）. ConclusionCompared with conventional Western medical treatment alone，conventional Western medical treatment combined with Tongnaoyin accelerates the repair of the blood-brain barrier in AIS patients，thereby ameliorating neurological impairment after AIS to improve the prognosis.

Aortic dissection is a life-threatening cardiovascular disease with devastating complications and high mortality. It requires rapid and accurate diagnosis and a focus on prognosis. Many laboratory tests are routinely performed in patients with aortic dissection including D-dimer, brain natriuretic peptide, cardiac troponin I, C-reactive protein, and procalcitonin. D-dimer shows vital performance in the diagnosis of aortic dissection, and brain natriuretic peptide, cardiac troponin I, C-reactive protein, and procalcitonin exhibits important value in risk stratification and prognostic effect in aortic dissection patients. Our review summarized the clinical utility of these laboratory tests in patients with aortic dissection, aiming to provide advanced and comprehensive evidence for clinicians to better understand these laboratory tests and help their clinical practice.

Objective: To analyze the unregistered treatment situation and its influencing factors among pulmonary tuberculosis patients in Quzhou City, Zhejiang Province from 2017 to 2023, so as to provide a basis for promoting the management of tuberculosis patients and optimizing disease prevention and control strategies. Methods: Data of pulmonary tuberculosis patients including demographic information, etiological results, and mortality status were collected through the China Disease Prevention and Control Information System Infectious Disease Reporting and Surveillance System and the Tuberculosis Management Information System. Pulmonary tuberculosis patients not matched in the Tuberculosis Management Information System were defined as unregistered treatment patients, and the unregistered treatment rate was analyzed. Factors affecting unregistered treatment among pulmonary tuberculosis patients were analyzed using a multivariable logistic regression model. Results: A total of 10 779 pulmonary tuberculosis patients were reported in Quzhou City from 2017 to 2023, including 7 700 males (71.44%) and 3 079 females (28.56%). There were 5 484 cases aged <65 years, accounting for 50.88%. Among them, 630 cases were unregistered treatment, with an unregistered treatment rate of 5.84% (95%CI: 5.42%-6.38%). Multivariable logistic regression analysis showed pulmonary tuberculosis patients aged ≥65 years (OR=1.829, 95%CI: 1.512-2.212) had a higher risk of being unregistered treatment than those aged <65 years; patients with non-local household registration (OR=5.710, 95%CI: 4.724-6.901) had a higher risk than local patients; and patients engaged in housework/unemployed (OR=2.001, 95%CI: 1.421-2.818) or other occupations (OR=2.396, 95%CI: 1.789-3.137) had a higher risk than farmers. The mortality of unregistered treatment pulmonary tuberculosis patients was higher than the registered treatment patients (26.67% vs. 5.02%),with a significantly elevated mortality risk (OR=7.147, 95%CI: 5.738-8.902). Conclusions The unregistered treatment rate among pulmonary tuberculosis patients was well controlled in Quzhou City from 2017 to 2023, but the elderly, patients with non-local household registration, and those engaged in housework/unemployed had a higher risk of unregistered treatment. It is recommended to improve medical and social security policies, strengthen health education on tuberculosis prevention, enhance treatment adherence, and reduce mortality risk.

Objective To explore basement membrane markers and potential drugs for treatment in idiopathic pulmona-ry fibrosis(IPF).Methods IPF-related datasets were downloaded from the Gene Expression Omnibus(GEO)database,processed to construct basement membrane gene expression matrices associated with IPF,and screened for differential basement membrane genes(DEBMs);DEBMs were enriched for function and pathways,and machine learning algorithms were used to ob-tain candidate signature genes,receiver operating characteristic(ROC)curves were used to identify signature genes and con-struct a nomogram.We performed ssGSEA analysis to explore the correlation between signature genes and immune cells and their functions and predicted the corresponding miRNAs and therapeutic drugs by signature genes.Results A total of 56 DEBMs were extracted;enrichment analysis showed that DEBMs were mainly enriched in"extracellular matrix tissue","extracellular structural tissue",etc.,and were closely related to"ECM-receptor interaction"and"local adhesion spot"pathways.The ma-chine learning has identified six candidate signature genes(TIMP3,P3H2,ITGA7,ITGA4,ADAMTS2,COL8A2),all of which meet the requirements of the signature genes by the ROC curve test,and the nomogram diagnostic value was outstanding(AUC=0.991 523);B cells and Macrophages in IPF were significantly different from the normal group.Finally,miRNAs were predicted to be dominated by miR-4305,miR-3684,progesterone,and tert-butyl hydroperoxide as therapeutic agents with strong relevance to IPF.Conclusion Signature genes and predictive miRNAs may serve as novel markers for IPF diagnosis,and pre-dictive drugs may be a potential source of drugs for treating IPF.

Objective:To explore the mechanism of long non-coding RNA RP11-79H23.3 in the development and progression of prostate cancer.Methods:The lnCAR database was used to analyze the RP11-79H23.3 content in prostate cancer tissues and adjacent tissues. RP11-79H23.3 content in prostate cancer cell lines C4-2B, LNCaP, DU-145, and 22Rv1 was detected by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR). Taking 22Rv1 as the research target, colony formation experiments and scratch experiments were used to detect the effects of overexpression of RP11-79H23.3 on the proliferation and migration of 22Rv1 cells. The LncRNome and lncACTdb databases were used to predict the downstream gene and binding sequences of RP11-79H23.3. The Cancer Genome Atlas (TCGA) database was used to analyze the correlation between RP11-79H23.3 and miR-410 expression in prostate cancer tissues. The binding of RP11-79H23.3 and miR-410 was confirmed by dual-luciferase reporter gene experiment. The effect of RP11-79H23.3 on the expression of miR-410 was detected by RT-qPCR. Western blotting was used to detect the effect of RP11-79H23.3 on the expression of phosphatase and tensin homolog/protein kinase B/mammalian target of rapamycin (PTEN/AKT/mTOR) signaling pathway proteins in 22Rv1 cells. The measurement data were expressed as mean ± standard deviation ( ± s), paired sample t-test was used for comparison between two groups, and one-way analysis of variance was used for comparison between multiple groups. Results:Compared with adjacent tissues, RP11-79H23.3 was lowly expressed in prostate cancer tissues ( P<0.01). Compared with normal prostate epithelial cells RWPE-1, RP11-79H23.3 was lowly expressed in prostate cancer cell lines C4-2B, LNCaP, DU-145, and 22Rv1 ( P<0.05). The expression of RP11-79H23.3 in 22Rv1 cells in the control group and RP11-79H23.3 group were 1.02 ± 0.30 and 8.94±1.95, respectively. 22Rv1 cells were successfully overexpressed RP11-79H23.3 compared with the control group ( t=4.04, P<0.01). The number of 22Rv1 cell clones in the control group and RP11-79H23.3 group were 166.10 ± 18.35 and 35.03±6.98, respectively. Overexpression of RP11-79H23.3 could inhibit the proliferation of 22Rv1 cells compared with the control group ( t=6.67, P<0.01). The migration rates of 22Rv1 cells in the control group and RP11-79H23.3 group were (67.40 ± 6.29)% and (26.42 ± 6.24)%, respectively. Overexpression of RP11-79H23.3 could inhibit the migration of 22Rv1 cells compared with the control group ( t=5.71, P<0.01) .Dual-luciferase reporter gene experiment showed that RP11-79H23.3 directly binds to miR-410 ( t=6.20, P<0.01). The expression of miR-410 in 22Rv1 cells in the control group and RP11-79H23.3 group were 6.22±1.39 and 1.05±0.23, respectively. RP11-79H23.3 could inhibit the expression of miR-410 in 22Rv1 cells compared with the control group ( t=3.68, P<0.01). At the same time, RP11-79H23.3 can inhibit the transduction of the PTEN/AKT/mTOR signaling pathway in 22Rv1 cells. Conclusion:RP11-79H23.3 blocks the PTEN/AKT/mTOR signaling pathway by inhibiting the expression of miR-410, thereby inhibiting the proliferation and migration of prostate cancer 22Rv1 cells.

ObjectiveTo investigate the changes in cerebral blood perfusion in patients with acute cerebral infarction after taking Tongnaoyin， a traditional Chinese medicine， based on head and neck computed tomography （CT） angiography （CTA） combined with brain CT perfusion imaging （CTP）. MethodA total of 240 patients with cerebral infarction of phlegm and blood stasis syndrome treated in Jiangsu Province Hospital of Traditional Chinese Medicine from March 2018 to September 2023 were randomly divided into a control group （99 cases） and a Tongnaoyin group （141 cases）. Based on the guidelines， the control group was treated with conventional treatment such as anti-aggregation， anticoagulation， lipid-lowering and plaque stabilization， brain protection， and supportive treatment. The Tongnaoyin group was treated with Tongnaoyin of 200 mL in warm conditions in the morning and evening on the basis of the control group. Both groups underwent CTA combined with CTP within 24 hours after admission， and they were reexamined by CTA and CTP in the sixth month after admission. The degree of intracranial artery stenosis was determined according to the North American Symptomatic Carotid Endarterectomy Trial （NASCET） method. The relative cerebral blood volume （rCBV）， relative cerebral blood flow （rCBF）， mean transit time （MTT）， and time to peak （TTP） of the lesion area before and after treatment were compared. The adverse outcomes of the two groups within six months after discharge were compared. ResultCompared with the group before treatment， the degree of vascular stenosis in the Tongnaoyin group was significantly reduced， and the difference was statistically significant （Z=105.369，P<0.05）. Compared with the control group after treatment， the improvement rate of vascular stenosis in the Tongnaoyin group was higher （χ²=84.179，P<0.01）， and the curative effect was better.After treatment， the rCBV and rCBF of patients in the Tongnaoyin group were significantly increased， and the difference was statistically significant （P<0.01）. MTT and TTP showed a trend of shortening， but the difference was not statistically significant. There was no statistically significant difference in rCBV， rCBF， MTT， and TTP in the control group. Compared with those in the control group after treatment， the rCBV and rCBF in the Tongnaoyin group were significantly increased， while MTT and TTP were significantly reduced （P<0.01）. After six months of discharge， the risk of poor prognosis in the Tongnaoyin group was significantly reduced compared with the control group （P<0.05）. ConclusionTongnaoyin has a good effect on improving cerebral blood perfusion in patients with acute cerebral infarction. It can be used as an effective supplement for the conventional treatment of ischemic stroke to improve clinical efficacy.

Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to analyze the expression difference of ZFP36-AS1 in bladder cancer cell lines (J82, RT-4, MGH-U3, 5637). MGH-U3 cells were randomly divided into negative control (NC) group and ZFP36-AS1 group, which were transfected with pcDNA3.1-NC plasmid and pcDNA3.1-ZFP36-AS1 plasmid, respectively. Colony formation assay and flow cytometry were used to analyze the proliferation activity and cell cycle of MGH-U3 cells, respectively. T lymphocytes were co-cultured with MGH-U3 cells in each group, and the levels of interleukin-10 (IL-10), γ-interferon (IFN-γ), and interleukin-4 (IL-4) in the supernatants of each group were detected by enzyme-linked immunosorbent assay (ELISA). The dual-luciferase reporter gene assay verified the targeting relationship between ZFP36-AS1 and miR-221. The effect of ZFP36-AS1 on the expression of miR-221 in MGH-U3 cells was detected by RT-qPCR. Western blotting was used to detect the effect of ZFP36-AS1/miR-221 axis on the protein expression of CDK3, Cyclin C, CDK5, Cyclin D1 and Cyclin D3 in MGH-U3 cells.Results:Compared with normal bladder tissue, ZFP36-AS1 was abnormally low-expressed in bladder cancer tissue ( P<0.01). Compared with SV-HUC-1 cells, ZFP36-AS1 was abnormally low-expressed in bladder cancer cell lines (J82, RT-4, MGH-U3, 5637) ( P<0.01), and the expression was lowest in MGH-U3 cells ( P<0.01). The number of MGH-U3 cell colonies formed in the NC group and the ZFP36-AS1 group were (220.80±34.65) and (77.84±19.11), respectively, and the number of MGH-U3 cell colonies formed in the ZFP36-AS1 group was significantly down-regulated, the difference was statistically significant ( P<0.01). The proportions of G 0/G 1 phase cells in NC group and ZFP36-AS1 group were (48.04±2.89)% and (72.89±3.46)%, respectively, and the proportion of S phase cells were (35.38±2.98)% and (20.62±2.56)%, respectively. The proportion of G 2/M stage cells was (16.59±1.46)% and (6.48±1.50)%, respectively. The proportion of cells in G 0/G 1 phase were up-regulated in ZFP36-AS1 group ( P<0.01), and the proportion of cells in S phase and G 2/M phase were both down-regulated ( P<0.01). Compared with the NC group, the levels of IL-4 and IFN-γ in the ZFP36-AS1 group were significantly up-regulated ( P<0.01), and the level of IL-10 was significantly down-regulated ( P<0.01). ZFP36-AS1 can target miR-221 ( P<0.01). The relative expression of miR-221 in the NC group and the ZFP36-AS1 group was 6.84±1.35 and 1.00±0.21, respectively. Compared with the NC group, overexpression of ZFP36-AS1 could significantly inhibit the expression of miR-221 ( P<0.01). Compared with the NC group, the expressions of CDK3, Cyclin C, CDK5, Cyclin D1, and Cyclin D3 in the ZFP36-AS1 group were significantly decreased. Conclusion:ZFP36-AS1 is abnormally low-expressed in bladder cancer, and it reduces the proliferation activity of bladder cancer cells and inhibits their immune escape by inhibiting the expression of miR-221.

Osteoarthritis (OA) is a chronic degenerative joint disease whose main characteristic is the destruction of articular cartilage, causing pain and disability in patients and seriously affecting their quality of life. OA can be induced by a variety of causes, and pathological changes in articular cartilage are considered to be one of the key driving factors for the occurrence of OA. High mobility group box-1 protein (HMGB1), as a non-histone protein in eukaryotic cells, can participate in regulating the inflammation and apoptosis process of OA chondrocytes, thus leading to the occurrence of OA. This article reviews the research on the mechanism of HMGB1 in OA chondrocytes, with a view to providing new ideas for the clinical prevention and treatment of OA.

The treatment of acute Stanford type A aortic dissection has always been extremely challenging. Organ malperfusion syndrome is a common severe complication of acute aortic dissection, which can cause organ ischemia and internal environment disorder. Malperfusion increases early mortality, and impacts the long-term prognosis. In recent years, many scholars have done some studies on aortic dissection complicated with malperfusion. They explored the pathogenesis, proposed new classification, and innovated new treatment strategies. However, at present, the treatment strategies of acute Stanford type A aortic dissection complicated with organ malperfusion are different at different centers and consensus on its treatment is still lacking. Therefore, this review summarized the pathogenesis, classification, treatment strategy, and prognosis of acute Stanford type A aortic dissection complicated with malperfusion.
