OBJECTIVE To investigate the effect and mechanism of bumetanide on lung injury in chronic obstructive pulmonary disease （COPD） model rats. METHODS COPD rat model was induced by lipopolysaccharide， and they were randomly divided into model group （COPD group）， bumetanide low-dose and high-dose groups （Bumetanide-L group， Bumetanide-H group）， bumetanide high-dose+Yes-associated protein/transcriptional coactivator containing PDZ-binding motif （YAP/TAZ） signaling pathway activator group （Bumetanide-H+PY-60 group）， with 12 rats in each group. Another 12 normal rats were selected as normal control group （Control group）. Thirty minutes before modeling， bumetanide/normal saline was inhaled or/and PY-60/ normal saline was injected into the tail vein. On the next day after the completion of modeling and drug administration， the pulmonary function index of the rats in each group was measured [forced expiratory volume in 0.3 seconds （FEV0.3）， forced vital capacity （FVC）， peak expiratory flow （PEF）， FEV0.3/FVC]. The levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6） and IL-1β in bronchoalveolar lavage fluid （BALF） were determined； the pathological morphology of lung tissue and degree of pulmonary fibrosis were observed. The expression levels of transforming growth factor- β （TGF- β）， α -smooth muscle actin （α-SMA） and TAZ protein as well as the phosphorylation of YAP protein in lung tissues were detected. RESULTS Compared with COPD group， the pathological injury of lung tissue in Bumetanide-L and Bumetanide-H groups was alleviated； the exfoliation of lung epithelial cells， tube wall thickening and the degree of pulmonary fibrosis were alleviated； inflammatory cell infiltration was reduced， and blue collagen deposition was reduced； FEV0.3， FVC， FEV0.3/FVC and PEF were significantly increased， while the lung injury score， levels of TNF-α， IL-6， IL-1β， expression levels of TGF-β， α-SMA and TAZ protein and the phosphorylation of YAP protein were significantly decreased （P＜0.05）. PY-60 could significantly reverse the improvement effects of bumetanide on above indexes （P＜0.05）. CONCLUSIONS Bumetanide can alleviate lung injury， inflammatory response and pulmonary fibrosis in COPD rats， and its mechanism is related to inhibiting YAP/TAZ signaling pathway.

Objective:To understand the impact of diet on glycemic control in community-managed patients with type 2 diabetes mellitus (T2DM) and provide evidence for implementing prevention strategies and measures for diabetes patients.Methods:Eight communities were randomly selected from Changshu and Wuhan in 2015, and T2DM patients managed in the community were selected to conduct questionnaire surveys, physical measurements, and blood glucose testing. Factor analysis was used to obtain dietary patterns. A binary logistic regression model was used to analyze the factors affecting glycemic control.Results:Finally, 1 818 T2DM patients were included, and the control rate of FPG was 57.59% (95% CI: 55.30%-59.86%), and the control rate of 2 h postprandial blood glucose (2 h PBG) was 24.90% (95% CI: 22.93%- 26.91%). Five dietary patterns were obtained by factor analysis: animal food pattern, fruit-aquatic products-potato patterns, vegetable-grain pattern, egg-milk-bean pattern, and oil-salt patterns. No-conditional multivariate logistic regression analysis showed that after adjusting for confounding factors, the reduced probability of FPG control was related to animal food pattern ( OR=0.71, 95% CI: 0.52-0.98) and fruit-aquatic products-potato patterns ( OR=0.71, 95% CI: 0.51-0.97). The decrease in the 2 h PBG control probability was related to fruit-aquatic products-potato patterns ( OR=0.60, 95% CI: 0.40-0.90). The increased probability of FPG and 2 h postprandial glucose control were both related to vegetable-grain pattern ( OR=1.41, 95% CI: 1.03-1.94; OR=1.68, 95% CI: 1.13-2.51) and egg-milk-bean pattern ( OR=1.75, 95% CI: 1.25-2.46; OR=1.56, 95% CI: 1.00-2.42). Compared with the Q4 group of egg-milk-bean pattern, the FPG control rate of the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q2 group), egg-milk-bean pattern ( Q3 group)" was higher ( OR=6.79, 95% CI: 1.15-40.23, P=0.035). Compared with the Q4 group of vegetable-grain pattern, the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q3 group), egg-milk-bean pattern ( Q2 group), oil-salt pattern ( Q2 group)" had higher control rate of 2 h PBG ( OR=12.78, 95% CI: 1.26-130.05, P=0.031). Conclusions:A proper combination of dietary patterns and dietary patterns are more conducive to the control of FPG and 2 h PBG in T2DM patients managed in the communities of Wuhan and Changshu. Patient nutrition education should be strengthened, and the food-matching ability of patients should be improved.

Hearing loss has become increasingly prevalent and causes considerable disability, thus gravely burdening the global economy. Irreversible loss of hair cells is a main cause of sensorineural hearing loss, and currently, the only relatively effective clinical treatments are limited to digital hearing equipment like cochlear implants and hearing aids, but these are of limited benefit in patients. It is therefore urgent to understand the mechanisms of damage repair in order to develop new neuroprotective strategies. At present, how to promote the regeneration of functional hair cells is a key scientific question in the field of hearing research. Multiple signaling pathways and transcriptional factors trigger the activation of hair cell progenitors and ensure the maturation of newborn hair cells, and in this article, we first review the principal mechanisms underlying hair cell reproduction. We then further discuss therapeutic strategies involving the co-regulation of multiple signaling pathways in order to induce effective functional hair cell regeneration after degeneration, and we summarize current achievements in hair cell regeneration. Lastly, we discuss potential future approaches, such as small molecule drugs and gene therapy, which might be applied for regenerating functional hair cells in the clinic.

Objective:To compare the difference between virtual surgical planning(VSP)position and postoperative real position of maxilla and condyle,and to explore the degree of intraoperative realization of VSP after orthognathic surgery.Methods:In this study,36 patients with mandibular protrusion de-formity from January 2022 to December 2022 were included.All the patients had been done bilateral sagittal split ramus osteotomy(SSRO)combined with Le Fort Ⅰ osteotomy under guidance of VSP.The VSP data(T0)and 1-week postoperative CT(T1)were collected,the 3D model of postoperative CT was established and segmented into upper and lower jaws in CCMF Plan software.At the same time,accor-ding to the morphology of palatal folds,the virtual design was registered with the postoperative model,and the unclear maxillary dentition in the postoperative model was replaced.Then the postoperative model was matched with VSP model by registration of upper skull anatomy that was not affected by the opera-tion.The three-dimensional reference plane and coordinate system were established.Selecting anatomical landmarks and their connections of condyle and maxilla for the measurement,we compared the coordinate changes of marker points in three directions,and the angle changes between the line connecting the marker points and the reference plane to analyze the positional deviation and the angle deviation of the postoperative condyle and maxilla compared to VSP.Results:The postoperative real position of the maxilla deviates from the VSP by nearly 1 mm in the horizontal and vertical directions,and the anteropos-terior deviation was about 1.5 mm.In addition,most patients had a certain degree of counterclockwise rotation of the maxilla after surgery.Most of the bilateral condyle moved forward,outward and downward(the average distance deviation was 0.15 mm,1.54 mm,2.19 mm,respectively),and rotated forward,outward and upward(the average degree deviation was 4.32°,1.02°,0.86°,respectively)compared with the VSP.Conclusion:VSP can be mostly achieved by assistance of 3D printed occlusal plates,but there are certain deviations in the postoperative real position of maxilla and condyle compared with VSP,which may be related to the rotation axis of the mandible in the VSP.It is necessary to use patient personalized condylar rotation axis for VSP,and apply condylar positioning device to further improve surgical accuracy.

Portal vein thrombosis （PVT） is one of the common complications during the natural course of liver cirrhosis and has an important influence on the progression of liver cirrhosis. This article mainly summarizes the research advances in the risk factors for PVT. There are many risk factors for PVT， and Virchow’s triad， namely venous stasis， hypercoagulability， and vascular endothelial injury and systemic inflammation caused by surgery or trauma， are considered the main reasons for the development and progression of PVT. At present， more prospective studies are still needed to validate the predictive models for the risk of PVT that have certain application prospects in clinical practice. Cirrhotic patients with PVT tend to have a poor prognosis， and complete obstructive PVT is associated with increased mortality after liver transplantation. Recent studies have shown that prophylactic anticoagulant therapy is safe and effective in patients with liver cirrhosis and can thus help with the prevention and treatment of PVT.

OBJECTIVE To mine and analyze the post-marketing adverse drug event （ADE） signals of irinotecan in adults and children populations， and to provide a reference for clinical safe medication. METHODS ADE reports of irinotecan from the first quarter of 2004 to the first quarter of 2023 in the US FDA adverse event reporting system database were extracted and the risk signals of irinotecan were detected through the reporting odds ratio and proportional reporting ratio. Statistical analysis was performed for ADE reports and signals of patients aged＜18 years （children） and ≥18 years （adults）. RESULTS A total of 8 013 ADE reports with irinotecan as the primary suspect drug were identified， including 7 656 and 357 ADE reports in adults and children， respectively. A total of 518 and 75 ADE signals were detected in the adults and children， and the mainly involved systems and organs including gastrointestinal disorders， blood and lymphatic system disorders， systemic disorders and various reactions at the administration site， etc. Most of the top 20 ADE signals in terms of frequency were documented in the drug instructions of irinotecan. New ADE signals in adults included peripheral neuropathy， oral mucosal inflammation， pulmonary embolism， epidermal nevus syndrome and reproductive toxicity， while hypertension， progressive neoplasms， tumor lysis syndromes， and embolism were new ADE signals in children. CONCLUSIONS The above new suspected high-risk signals not mentioned in the instructions should raise a high level of alertness in clinical practice of irinotecan.

Objective To construct a risk prediction model for liver cancer in patients with chronic hepatitis C based on seven different machine learning algorithms and select the optimal model. Methods A total of 236 patients with chronic hepatitis C were selected as the research subjects. Patients were divided into a case group and a control group according to whether liver cancer occurs. Prediction models were constructed based on seven machine learning algorithms including classification and regression tree, random forest, gradient boosting decision tree, extreme gradient boosting (XGBoost), logistic regression, K-near neighbor, and support vector machine. The Shapley additive explanations (SHAP) algorithm was used to interpret the best prediction model. Results Among the seven models, the XGBoost model had the best comprehensive prediction performance (accuracy of 0.933, sensitivity of 0.775, specificity of 0.960, area under the ROC curve of 0.956, F1 score of 0.764). The SHAP algorithm suggested that AFP, age, AST, diabetes, BMI, PLT, ALT, liver cysts, FIB-4, and gender contributed to the model decision and are the risk factors for liver cancer in patients with chronic hepatitis C. Conclusion This study develops an interpretable machine learning model based on the XGBoost algorithm, which has a good reference value for individualized monitoring of liver cancer in patients with chronic hepatitis C.
