Objective To analyze drug resistance and clustering of environmental and clinical isolates of Acinetobacter baumannii (A. baumannii) in ICU of a medical institution in Shanghai. Methods The isolates of A. baumannii from ICU environments and clinic were used to analyze the contamination and distribution in 2021-2024. Antimicrobial susceptibility testing was carried out with microbroth dilution method. Whole genome sequencing was performed out of strains for MLST typing and SNP clustering. Results The detection rate of contamination in ICU environment was 7.67%, and the most serious contamination was found in pillows, bedding, hospital gowns and other items that patients directly contacted. Clinical isolates were predominantly from sputum specimens. The environmental and clinical isolates had a high level of resistance to third generation cephalosporins, third generation quinolones and carbapenems (more than 85%). Environmental isolates had a low level of resistance to polymyxin B, but none of the clinical isolates were resistant. MLST typing showed that ST2 was the dominant clone (66.67%), and SNP clustering found that isolates from different sources but with the same ST type were clustered together. Conclusion ST2 is the dominant clone of A. baumannii isolates in this medical institution, and there is cross-contamination between different samples. Monitoring of drug resistance and disinfection should be further strengthened to prevent the emergence and spread of pan-resistant or even fully resistant strains.

Objective To explore the risk factors of progression to dementia within 2 years in patients with recent subcortical small infarction (RSSI) complicated with cognitive dysfunction. Methods A total of 340 patients with RSSI complicated with cognitive dysfunction who were treated in the hospital and completed 2-year follow-up were selected from February 2021 to February 2025. According to whether the patients progressed to dementia, they were classified into dementia group (n=105) and non-dementia group (n=235). The clinical data were compared between both groups, and the independent risk factors were screened by Logistic regression analysis. Results Multivariate logistic regression analysis suggested that history of hypertension (OR=1.919), history of diabetes mellitus (OR=1.597), multiple infarctions (OR=1.455), severe white matter lesions (OR=1.595), no cognitive function training (OR=1.923), increased infarct size (OR=1.069), reduced MMSE score (OR=0.945) and increased levels of NfL (OR=1.049) and IL-6 (OR=1.038) were independent risk factors for the progression to dementia (all P<0.05). Conclusion The progression to dementia in patients with recent subcortical small infarction and cognitive dysfunction is affected by multiple factors. In clinical practice, the integration of vascular risk factors, imaging features, cognitive assessment and serum biomarkers (NfL, IL-6) helps to construct an early risk prediction model and implement targeted interventions for high-risk groups.

This report described the multidisciplinary management of a preterm infant with congenital tracheal agenesis (TA). The infant, delivered via cesarean section at 32 +5 weeks' gestation, had Apgar scores of 6 and 8 at 1 and 5 minutes, respectively. Although skin color improved after 30 seconds of bag-mask ventilation, the infant exhibited no cry, weak spontaneous breathing, and failed multiple intubation attempts. The patient was transferred to Anhui Children's Hospital of Fudan University under continuous bag-mask positive-pressure ventilation at 3 hours after birth (September 10, 2024). Combined imaging and fiberoptic bronchoscopy confirmed TA (Floyd type Ⅱ/Faro type C) with multiple anomalies, including duodenal atresia, aortic coarctation, and butterfly vertebrae. Whole-genome sequencing revealed a suspected mosaic SCN2A c.5317G>A variant (wild-type parents) and an ERCC5 c.2974C>T heterozygous variant inherited from the mother (homozygous). Following esophageal intubation, invasive mechanical ventilation, and continuous gastrointestinal decompression, respiratory distress significantly improved with a stabilized condition. The infant died 30 hours after birth following treatment withdrawal.

Objective:To explore the clinical, imaging, and pathological features of glottic squamous cell carcinoma of the larynx and their relationship with prognosis. Methods:A retrospective analysis was conducted on the clinical, imaging, and pathological data of 130 patients with glottic squamous cell carcinoma of the larynx who were treated at the First People's Hospital of Yinchuan and the General Hospital of Ningxia Medical University from January 2018 to March 2023. Imaging examinations （CT and MRI） were used to evaluate the lesion boundary clarity, density, enhancement nature, and enhancement degree. Postoperative pathological examination was used to determine the pathological nature, immunohistochemistry, etc. Statistical methods such as χ² test, Spearman correlation analysis, multivariate logistic regression analysis, and Kaplan-Meier method were used to analyze the data. Results:Among the 130 patients, 127 were male and 3 were female, with an average age of （61.92±9.595） years. There was a correlation between clinical, imaging, and pathological features. Multivariate analysis showed that heterogeneous MRI density （OR=12.414;P=0.019） and squamous cell carcinoma as a subtype were correlated. The initial symptom of non-hoarseness （HR=6.045;P=0.010） and unclear MRI boundary （HR=12.559; P=0.029） were independent risk factors for poor prognosis in patients with glottic squamous cell carcinoma of the larynx. Conclusion:There is a correlation between the clinical, imaging, and pathological features of patients with glottic squamous cell carcinoma of the larynx, and they can affect prognosis. The initial symptom of non-hoarseness and unclear MRI boundary of the tumor are independent risk factors for poor prognosis.

Objective:To investigate the clinical characteristics and major allergens of patients with pollen-food allergy syndrome（PFAS） and their correlation with the severity of symptoms, and to provide a basis for identifying high-risk patients, optimizing the allergen testing process and developing individualized dietary management strategies. Methods:The clinical data of 166 patients with PFAS admitted to our hospital from January 2021 to July 2023 were retrospectively analyzed. The clinical symptoms, pollen types and food allergy of the patients were analyzed by questionnaire survey and serum specific IgE detection. phi coefficient, Apriori algorithm modeling and multivariate logistic regression analysis were used to evaluate the association between allergen and symptom severity. Results:Artemisia pollen was the most common allergen in this area, with a positive rate of 96.39%. Peach and mango were the most common food allergens, which caused allergic reactions in 24.10% and 22.89% of patients, respectively. Oral mucosal symptoms were the main symptoms. Correlation analysis showed that there was a correlation between pollen allergens and allergenic food. Association rule analysis showed that when the patient was allergic to the combination of peanuts and trees, the probability of high severity of symptoms was 82.35%. Multivariate analysis showed that ragweed allergy was significantly positively correlated with the severity of PFAS symptoms. Conclusion:Artemisia pollen and related food allergens play an important role in the pathogenesis of PFAS. Association rule mining and network map analysis revealed direct associations between peanut and tree combination allergy and symptom severity, as well as potential links between other inhaled allergens and specific food allergies. Ragweed and peach allergy are independent risk factors for the aggravation of PFAS symptoms, which can be used as early warning indicators. These results help to improve the screening of high-risk patients and the construction of regional allergen databases.

Objective To explore the effects of Emotional Freedom Techniques combined with PERMA model intervention on fear of disease progression and quality of life in postoperative liver cancer patients.Methods A total of 58 liver cancer patients admitted from September 2023 to February 2024 were randomly divided into the experimental group(n=29)and the control group(n=29)using a random number table method.The experimental group received Emotional Freedom Techniques combined with PERMA-based positive psychological intervention,while the control group received the holistic nursing and routine psychological guidance.Both groups underwent the continuous intervention for 8 weeks.Outcomes were assessed using the Fear of Progression Questionnaire-Short Form(FoP-Q-SF),Distress Thermometer(DT),Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS),Cancer Fatigue Scale(CFS),Athens Insomnia Scale(AIS)and Index of Well-Being(IWB).Results After the intervention,the experimental group showed the significantly lower scores than those in the control group in FoP-Q-SF(24.97±2.34/34.10±8.46),DT(2.24±0.95/2.93±1.33),SAS(49.55±1.35/58.55±4.60),SDS(51.86±1.58/61.79±4.00),CFS(4.03±0.94/5.10±1.18),and AIS(2.45±1.12/4.07±0.96)(all P<0.05),while the IWB score(10.56±1.74/7.39±2.05)was significantly higher than that in the control group(P<0.05).Conclusion The combination of Emotional Freedom Techniques and PERMA model intervention can effectively alleviate the disease-related fears,improve the negative emotions,reduce the physical symptoms and enhance the subjective well-being in postoperative liver cancer patients,and it has a significant clinical application value.

Objective:To investigate the expression of the proinflammatory factor IL-18-mediated NOD-like receptor thermal protein domain associated protein 3/nuclear factor κB(NLRP3/NF-κB)signaling pathway in penile tissues of rats with high-fat diet-in-duced erectile dysfunction(ED),and to explore the intervention effect of sildenafil.Methods:Fifty-five sexually normal male SD rats were randomly divided into 10 cases as the normal control group,and the rest of the rats were fed with high-fat chow to establish the ED rat model,and the successfully screened ED rats were randomly divided into the ED group,the Sil group,the IL-18 group,and the IL-18+Sil group,with 8 rats in each group.Following 14 days of nonstop treatment,the morphological alterations in the penile tis-sue were observed by HE staining.Using immunohistochemistry,the amount and distribution of NF-κB p65 and Adropin in penile tis-sues were found.RT-qPCR was used to identify the expression of NLRP3 and NF-κB p65 mRNA in penile tissues.Western blot exami-nation showed the expression of the proteins NLRP3,pro-IL-18,p-NF-κB p65,NF-κB p65,and Adropin in penile tissues.Results:The ED group showed altered penis tissue morphology,destroyed muscle fibers,enlarged sinus cavity,increased mRNA and protein expressions of NLRP3,p-NF-κB p65/NF-κB p65,and pro-IL-18(all P<0.05),and decreased Adropin protein expression(P<0.05).While the protein expression of Adropin was increased(P<0.05),the mRNA and protein expressions of NLRP3,p-NF-κB p65/NF-κB p65,and pro-IL-18 in the penis tissues were decreased(all P<0.05)when compared to the ED group.The muscle fibers and sinus cav-ities of the penis were recovered to varying degrees in the Sil group.The IL-18 group experienced the destruction of muscle fibers,an enlargement of the sinus cavity,an increase in the mRNA and protein expressions of NLRP3,p-NF-κB p65/NF-κB p65,and pro-IL-18 in the penile tissues(all P<0.05),as well as a decrease in the protein expression of Adropin(P<0.05).The rat penile tissues in the IL-18+Sil group showed variable degrees of recovery in the muscle fibers and sinus cavities when compared to the IL-18 group.Ad-ditionally,there was a drop(all P<0.05)in the expressions of NLRP3,pro-IL-18 m RNA and protein,p-NF-κB p65/NF-κB p65,and p-NF-κB p65 in the penile tissues.The expression of the Adropin protein was elevated(P<0.05).Conclusion:Significant changes have been observed in the NLRP3/NF-κB signaling pathway,which is regulated by IL-18,in the hyperlipidemia ED rat model.In ED rats,sildenafil can increase erectile function by promoting the production of Adropin and blocking the activation of this pathway.

Urinary incontinence is the most common complication after radical prostatectomy.Traditional Chinese medicine treatments for this disease,such as acupuncture,are diverse and have definite therapeutic effects.The disease is located in the bladder,and its etiology and pathogenesis are mostly related to the dysfunction of the kidney,spleen,triple energizer and other viscera.In view of the insufficiency of kidney essence,decline of the gate of vitality fire(mingmen fire),Qi deficiency leading to impaired bladder containment,compounded by obstruction of meridians from pathogenic factors including blood stasis,damp-heat,and phlegm turbidity.The"Shuanggu Yitong"acupuncture achieves"Dual fortification"through tonifying the kidney and primordial qi consolidation,combined with spleen strengthening and qi supplementation.Additionally,"purging"targets the elimination of blood stasis,phlegm turbidity,damp-heat and other solid evils.This integrated approach combines acupuncture and moxibustion modalities with reinforcing-reducing needle manipulation techniques,simultaneously addressing both the symptoms and root causes of the problem.By coordinating pathogen elimination with constitutional regulation,this method demonstrates favorable therapeutic outcomes in clinical practice and is worthy of further clinical promotion.

Objective:Based on the process theory of stress effect, the mediating effect of health literacy and perceived social support between perceived control and fatigue symptom of asthmatic patients was analyzed, which provide the evidence for the formulation of intervention programs to relieve fatigue in patients.Methods:Adopting a cross-sectional survey design, from January 2019 to November 2023, asthmatic patients at The First Affiliated Hospital of Anhui Medical University (Feidong County People′s Hospital) were selected by convenience sampling method and investigated by the General Information Questionnaire, Fatigue Severity Scale, Perceived Control of Asthma Questionnaire, Health Literacy Management Scale, and Perceived Social Support Scale. Pearson correlation analysis was used to investigate the correlation between fatigue symptom, perceived control, health literacy, and perceived social support in asthma patients. A structural equation model was constructed using AMOS24.0 software and conduct mediation analysis.Results:A total of 260 questionnaires were distributed, and 241 valid questionnaires were collected. There were 110 males and 131 females aged (55.48 ± 15.03) years old. The scores of Fatigue Severity Scale, Perceived Control of Asthma Questionnaire, Health Literacy Management Scale, and Perceived Social Support Scale were (4.27 ± 1.68), (31.72 ± 8.51), (85.71 ± 19.36), (46.97 ± 11.79) points, respectively. Pearson correlation analysis showed that fatigue symptom was negatively correlated with perceived control, health literacy, and perceived social support ( r=-0.719, -0.716, -0.767, all P<0.01). The mediating model showed that perceived control had a significant direct effect on fatigue symptom ( β=-0.204, 95% CI-0.252--0.169). Moreover, perceived control also indirectly affected fatigue symptom through the independent mediating effect of health literacy ( β=-0.378, 95% CI-0.405--0.202), the independent mediating effect of perceived social support ( β=-0.227, 95% CI-0.381--0.203), and the chain mediating effect of health literacy and perceived social support ( β=-0.089, 95% CI-0.142--0.025), which accounting for 77.3% of the total effect. Conclusions:Health literacy and perceived social support play a mediating role in the correlation between perceived control and fatigue symptom, which can promote health literacy and perceived social support and thus alleviate fatigue symptom in asthmatic patients.
