OBJECTIVE To compare the efficacy and safety of infliximab（IFX）， ustekinumab（UST） and vedolizumab（VDZ） in the treatment of active Crohn’s disease （CD）. METHODS The patients with active CD who were diagnosed and initially received any of the aforementioned biologics at the First Affiliated Hospital of the USTC （Anhui Provincial Hospital） from January 2020 to December 2023 were selected as the study subjects. They were divided into the IFX group （34 cases）， the UST group （37 cases）， and the VDZ group （15 cases） based on their treatment regimens. Patients in all three groups received induction and maintenance therapy with IFX， UST or VDZ for at least 12 months. The CD Activity Index （CDAI） scores and their changes from baseline （ΔCDAI）， clinical remission rates， clinical response rates， nutritional indicators [body mass index （BMI）， albumin （ALB）， hemoglobin （HGB）]， and inflammatory markers [C-reactive protein （CRP）， erythrocyte sedimentation rate （ESR）] of three groups after the induction phase （9th week of treatment） and during the maintenance phase （12th month of treatment） were compared. Additionally， the cumulative clinical remission rates at 1 year of treatment and the incidence of adverse events （AEs） were compared. RESULTS There were no statistically significant differences in the aforementioned baseline indicators among the three groups （ P ＞0.05）. In all three groups， the CDAI scores were significantly lower after the induction phase and during the maintenance phase， compared to the baseline （ P ＜0.05）. In the IFX group， CDAI scores at the above time points were significantly lower than those in the UST and VDZ groups during the same periods （ P ＜0.05）， and the absolute value of ΔCDAI during the maintenance phase was significantly higher than that in the VDZ group （ P ＜0.05）. The clinical remission rate in the IFX group during the maintenance phase was significantly higher than that in the UST and VDZ groups during the same period， and the clinical response rate was significantly higher than that in the VDZ group during the same period （ P ＜0.05）. The levels of ALB， HGB， CRP and ESR in the IFX group after the induction phase and during the maintenance phase， as well as the levels of CRP and ESR in the UST group after the induction phase， all improved significantly compared to the baseline. Furthermore， the levels of ALB and HGB in the IFX group were significantly higher than those in the UST and VDZ groups during the same period （ P ＜0.05）. The cumulative clinical remission rates among the three groups were significantly different （ P ＜0.05）， with patients in the IFX group achieving remission more rapidly and at a higher proportion. There was no statistically significant difference in the incidence of AEs among IFX， UST and VDZ groups （14.71%， 8.11% and 20.00%， respectively； P ＞0.05）； infusion reactions were the most common AEs in the IFX group （8.82%）. CONCLUSIONS Compared with UST and VDZ， IFX demonstrates a higher clinical remission rate during the maintenance phase， more effectively improves active CD patients’ nutritional status， and continuously reduces systemic inflammatory responses. However， clinicians should be mindful of the risk of adverse events， such as infusion reactions， associated with this drug.

Objective To compare the benefits and drawbacks of primary patch expansion versus pericardial tube right ventricular-pulmonary artery connection in patients diagnosed with pulmonary atresia with ventricular septal defect (PA/VSD). Methods A retrospective study was conducted on patients diagnosed with PA/VSD who underwent primary right ventricular-pulmonary artery connection surgery at our center between 2010 and 2020. Patients were categorized into two groups based on the type of right ventricular-pulmonary artery connection: a pericardial tube group and a patch expansion group. Clinical data and imaging findings were compared between the two groups. Results A total of 51 patients were included in the study, comprising 31 males and 20 females, with a median age of 12.57 (4.57, 49.67) months. The pericardial tube group included 19 patients with a median age of 17.17 (7.33, 49.67) months, while the patch expansion group consisted of 32 patients with a median age of 8.58 (3.57, 52.72) months. In both groups, the diameter of pulmonary artery, McGoon index, and Nakata index significantly increased after treatment (P<0.001). However, the pericardial tube group exhibited a longer extracorporeal circulation time (P<0.001). The reoperation rate was notably high, with 74.51% of patients requiring further surgical intervention, including 26 (81.25%) patients in the patch expansion group and 12 (63.16%) patients in the pericardial tube group. No statistical differences were observed in long-term cure rates or mortality between the two groups (P＞0.005). Conclusion In patients with PA/VSD, both patch expansion and pericardial tube right ventricular-pulmonary artery connection serve as effective initial palliative treatment strategies that promote pulmonary vessel development and provide a favorable foundation for subsequent radical operations. However, compared to the pericardial tube approach, the patch expansion technique is simpler to perform and preserves some intrinsic potential for pulmonary artery development, making it the preferred procedure.

ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

Background/Aims: Transmembrane 4 L six family member 1 (TM4SF1) is highly expressed and contributes to the progression of various malignancies. However, how it modulates hepatocellular carcinoma (HCC) progression and senescence remains to be elucidated. Methods: TM4SF1 expression in HCC samples was evaluated using immunohistochemistry and flow cytometry. Cellular senescence was assessed through SA-β-gal activity assays and Western blot analysis. TM4SF1-related protein interactions were investigated using immunoprecipitation-mass spectrometry, co-immunoprecipitation, bimolecular fluorescence complementation, and immunofluorescence. Tumor-infiltrating immune cells were analyzed by flow cytometry. The HCC mouse model was established via hydrodynamic tail vein injection. Results: TM4SF1 was highly expressed in human HCC samples and murine models. Knockdown of TM4SF1 suppressed HCC proliferation both in vitro and in vivo, inducing non-secretory senescence through upregulation of p16 and p21. TM4SF1 enhanced the interaction between AKT1 and PDPK1, thereby promoting AKT phosphorylation, which subsequently downregulated p16 and p21. Meanwhile, TM4SF1-mediated AKT phosphorylation enhanced PD-L1 expression while reducing major histocompatibility complex class I level on tumor cells, leading to impaired cytotoxic function of CD8+ T cells and an increased proportion of exhausted CD8+ T cells. In clinical HCC samples, elevated TM4SF1 expression was associated with resistance to anti-PD-1 immunotherapy. Targeting TM4SF1 via adeno-associated virus induced tumor senescence, reduced tumor burden and synergistically enhanced the efficacy of anti-PD-1 therapy. Conclusions Our results revealed that TM4SF1 regulated tumor cell senescence and immune evasion through the AKT pathway, highlighting its potential as a therapeutic target in HCC, particularly in combination with first-line immunotherapy.

Objective:To assess the effect of joint exposure to multiple air pollutants on sleep structure in patients with stable chronic obstructive pulmonary disease (COPD), identify key air pollutants, and analyze potential influencing factors.Methods:In this panel study, 92 stable COPD patients were recruited. From March 2021 to September 2023 in Beijing, all participants completed 254 nights of sleep monitoring. The total sleep duration, light sleep duration, deep sleep duration and rapid eye movement sleep duration and their respective proportions in total sleep duration were recorded. The exposure levels of fine particulate matter (PM 2.5), inhalable particulate matter (PM 10), nitrogen dioxide (NO 2), ozone (O 3), sulfur dioxide (SO 2), and carbon monoxide (CO) were estimated based on the infiltration factor method and time-activity logs of participants. To assess the lag effect of air pollutants, moving average concentrations of air pollutants from 0-1 day to 0-3 months were calculated. The linear mixed-effect model and Bayesian kernel machine regression (BKMR) model were used to assess the single and joint effects of air pollutants on sleep structure parameters in COPD patients, respectively. Results:All six types of air pollutants were associated with changes in sleep structure, manifesting as an increase in total sleep duration and light sleep proportion and a reduction in deep sleep proportion. The effects of O 3 were strongest at lag 0-6 days, while other air pollutants were at lag 0-3 months. Joint exposure to multiple air pollutants exerted significant joint effects on sleep structure, and NO 2 was identified as the dominant pollutant. NO 2 had a posterior inclusion probability (PIP) greater than 0.5 for light sleep proportion (PIP=0.691) and deep sleep proportion (PIP=0.957). With an interquartile range (IQR) increase of 8.6 μg/m 3 in NO 2 at lag 0-3 months, the light sleep proportion increased by 10.5% (95% CI: 2.2%-19.4%), and the deep sleep proportion decreased by 19.5% (95% CI:-30.6%- -6.8%). Conclusion:Joint exposure to air pollutants is associated with changes in sleep structure in stable COPD patients, and NO 2 may be a key pollutant.

OBJECTIVE To evaluate the economic burden of the intensive care unit(ICU)patients due to hospital-associated multidrug-resistant organisms(MDROs)infections based on propensity score matching(PSM)so as to provide evidence-based bases for prevention and control of hospital-associated MDROs infection and improvement of utilization efficiency of medical resources.METHODS A total of 2118 patients who were hospitalized in Zibo Central Hospital from Jan.1,2023 to Dec.31,2024 and conformed to the inclusion and exclusion criteria were re-cruited as the research subjects.The patients with hospital-associated MDROs infections were matched in a 1∶1 ratio by PSM(with the clamp value 0.02).Totally 309 pairs were successfully matched.The length of hospital stay and the costs were observed and compared between the MDROs group and the non-MDROs group.RESULTS The MDROs group was with the length of hospital stay 14.00 days longer than the non-MDROs group after the matching(Z=-5.750,P＜0.001),with the total cost of hospitalization increased by 91,420.84 yuan(Z=-8.271,P＜0.001).With the respect to the medical treatment expenses,the expenses of the MDROs group were higher than those of the non-MDROs group,covering the cost of medical service,therapeutic procedures,nursing,western medicine and TCM,and there were significant differences(P＜0.05).Among the differences in the costs between the two groups,the difference in the cost of western medicine was the most signif-icant(22,182.91 yuan),followed by the cost of clinical laboratory test for diagnosis(19,529.60 yuan)and the cost of therapeutic procedures(16,333.50 yuan).CONCLUSIONS The hospital-associated MDROs infections may lead to the extension of hospital stay length of the ICU patients,which then increases the economic burden.There-fore,it is necessary to strengthen the multidisciplinary collaboration and formulate corresponding measures so as to reduce the risk of such infections among the ICU patients.

Objective To analyze the application effect of size-specific dose estimate(SSDE)in radiation dose and images quality of coronary CT angiography(CCTA).Methods A retrospective study was conducted on 56 patients undergoing CCTA at the First Affiliated Hospital of Chongqing Medical University between February 2022 and February 2025.These patients were assigned to observation group(SSDE injection),while another 56 patients undergoing CCTA during the same period were enrolled as routine group(traditional injection).The two groups were compared for coronary enhancement value,images quality score,objective parameters of images quality[image noise,CT value,contrast to noise ratio(CNR),signal to noise ratio(SNR)],radiation dose parameters[dose-length product(DLP),CT dose index volume(CTDIvol),effective dose(ED)],anteroposterior diameter,left-right diameter and fsize.Results The CCTA image quality score and coronary enhancement value in observation group were significantly higher than those in routine group(P<0.05).Compared with routine group,observation group had higher CT value,CNR,and SNR,as well as lower image noise(P<0.05).The CTDIvol,ED,DLP and SSDE of observation group were lower than those of routine group(P<0.05).The?size in observation group was smaller,while anteroposterior diameter and left-right diameter were longer than those in routine group(P<0.05).Conclusion The application of SSED protocol in CCTA scanning can effectively improve radiation dose and images quality.

BACKGROUND: Without timely and effective rehabilitation, hearing loss may profoundly affect human life quality. China has a large population of hearing-impaired individuals, which imposes a heavy health burden on society. Moreover, this population is projected to increase rapidly owing to China's aging society. METHODS: We used data from a population-representative epidemiological investigation of hearing loss and ear diseases in four Chinese provinces. We estimated the national prevalence using multiple linear regression of the age-group proportions and prevalence in 31 provinces with clustering analysis. We used years lived with disability (YLDs) to analyze the disease burden and forecasted the prevalence of hearing loss by 2060 in China. RESULTS: An estimated 115 million people had moderate-to-complete hearing loss in 2015 across the 31 provinces of China (8.4% of 1.37 billion people). Of these, 85.7% were older than age 50 years (99 million people) and 2.4% were younger than 20 years old (2.8 million people). Of all YLDs attributable to hearing loss, 68.9% were attributable to moderate-to-complete cases. By 2060, a projected 242 million people in China will have moderate-to-complete hearing loss, a 110.0% increase from 2015. CONCLUSIONS The hearing loss prevalence in China is high. Population aging and socioeconomic factors substantially affect the prevalence and severity of hearing loss and the disease burden. The prevalence and severity of hearing loss are unevenly distributed across different provinces. Future public health policies should take these trends and regional variations into account.
