With the widespread use of antibiotics, drug-resistant bacterial infections have become a significant threat to human health. Finding new antibacterial strategies that can effectively control drug-resistant bacterial infections has become an urgent task. Unlike small molecule drugs that target bacterial proteins, antisense oligonucleotide (ASO) can target genes related to bacterial resistance, pathogenesis, growth, reproduction and biofilm formation. By regulating the expression of these genes, ASO can inhibit or kill bacteria, providing a novel approach for the development of antibacterial drugs. To overcome the challenge of delivering antisense oligonucleotide into bacterial cells, various drug delivery systems have been applied in this field, including cell-penetrating peptides, lipid nanoparticles and inorganic nanoparticles, which have injected new momentum into the development of antisense oligonucleotide in the antibacterial realm. This review summarizes the current development of small nucleic acid drugs, the antibacterial mechanisms, targets, sequences and delivery vectors of antisense oligonucleotide, providing a reference for the research and development of antisense oligonucleotide in the treatment of bacterial infections.

Acute lung injury(ALI) is a critical clinical condition primarily characterized by refractory hypoxemia and infiltration of inflammatory cells in lung tissue, which can progress into a more severe form known as acute respiratory distress syndrome(ARDS). Immune cells and inflammatory cytokines play important roles in the progression of the disease. Due to its unclear pathogenesis and the lack of effective clinical treatments, ALI is associated with a high mortality rate and severely affects patients' quality of life, making the search for effective therapeutic agents particularly urgent. Ginseng Radix et Rhizoma, the dried root of the perennial herb Panax ginseng from the Araliaceae family, contains active ingredients such as saponins and polysaccharides, which possess various pharmacological effects including anti-tumor activity, immune regulation, and metabolic modulation. In recent years, studies have shown that ginsenosides exhibit notable effects in reducing inflammation, ameliorating epithelial and endothelial cell injury, and providing anticoagulant action, indicating their comprehensive role in alleviating lung injury. This review summarizes the pathogenesis of ALI and the molecular mechanisms through which ginsenosides act at different stages of ALI development. The aim is to provide a scientific reference for the development of ginsenoside-based drugs targeting ALI, as well as a theoretical basis for the clinical application of Ginseng Radix et Rhizoma in the treatment of ALI.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

OBJECTIVE: As an age-related neurodegenerative disease, the prevalence of mild cognitive impairment (MCI) increases with age. Within the framework of traditional Chinese medicine, spleen-kidney deficiency syndrome (SKDS) is recognized as the most frequent MCI subtype. Due to the covert and gradual onset of MCI, in community settings it poses a significant challenge for patients and their families to discern between typical aging and pathological changes. There exists an urgent need to devise a preliminary diagnostic tool designed for community-residing older adults with MCI attributed to SKDS (MCI-SKDS). METHODS: This investigation enrolled 312 elderly individuals diagnosed with MCI, who were randomly distributed into training and test datasets at a 3:1 ratio. Five machine learning methods, including logistic regression (LR), decision tree (DT), naive Bayes (NB), support vector machine (SVM), and gradient boosting (GB), were used to build a diagnostic prediction model for MCI-SKDS. Accuracy, sensitivity, specificity, precision, F1 score, and area under the curve were used to evaluate model performance. Furthermore, the clinical applicability of the model was evaluated through decision curve analysis (DCA). RESULTS: The accuracy, precision, specificity and F1 score of the DT model performed best in the training set (test set), with scores of 0.904 (0.845), 0.875 (0.795), 0.973 (0.875) and 0.973 (0.875). The sensitivity of the training set (test set) of the SVM model performed best among the five models with a score of 0.865 (0.821). The area under the curve of all five models was greater than 0.9 for the training dataset and greater than 0.8 for the test dataset. The DCA of all models showed good clinical application value. The study identified ten indicators that were significant predictors of MCI-SKDS. CONCLUSION The risk prediction index derived from machine learning for the MCI-SKDS prediction model is simple and practical; the model demonstrates good predictive value and clinical applicability, and the DT model had the best performance.

Objective:To evaluate the effects of glutamine-enriched parenteral nutrition on short-term postoperative outcomes compared with conventional nutritional support in colorectal cancer patients with enteral nutrition intolerance after surgery.Method:A retrospective cohort study was conducted to collect clinical data from colorectal cancer patients who underwent radical resection at the Department of Gastrointestinal Surgery of Zunyi Medical University Affiliated Hospital from January 2019 to December 2021.The differences in postoperative complication rates,perioperative nutritional indicators,and inflammatory factors between the two groups were analyzed.SPSS 29.0 software was used for statistical analysis.Result:Based on whether glutamine was added to parenteral nutrition,178 patients were divided into a control group(conventional nutritional therapy,n=120)and an observation group(glutamine enhanced nutritional therapy,n=58).The incidence of postoperative complications(Clavien Dindo grade≥III)in the control and observation groups was 14.17%(17/120)and 3.45%(2/58),respectively,with a statistically significant difference(P=0.030).The observation group recovered faster than the control group in terms of time to first expectoration,defecation and intake of liquid diet after surgery,and had a shorter hospital stay after surgery(P<0.05).However,there was no significant difference in the 30-day readmission rate between the two groups(P=0.393).There was no statistically significant difference in the changes in total protein,albumin,pre-albumin,neutrophil/lymphocyte ratio and endogenous creatinine clearance rate between the two groups of patients after surgery(P>0.05).There were also significant differences in the changes in lymphocyte count,white blood cell count,neutrophil percentage,alanine aminotransferase,aspartate aminotransferase,total bilirubin,and urea nitrogen levels between the two groups of patients after surgery(P<0.05).Conclusion:Compared with regular nutritional support,postoperative parenteral glutamine supplementation can reduce the incidence of postoperative complications in colorectal cancer patients,promote recovery of bowel function,shorten postoperative hospital stay,improve patient immune function and reduce inflammatory levels.

Objective To comparatively analyze the clinical characteristics of primary bilateral macronodular adrenal hyperplasia(PBMAH)and adrenal cortisol-producing Adenoma(CPA),and enhance the understanding of two diseases.Methods The clinical data of 85 PBMAH patients(PBMAH group)and 195 CPA patients(CPA group)diagnosed at Department of Endocrinology,the First Medical Center of Chinese PLA General Hospital,from September 2014 to August 2024 were retrospectively analyzed.The demographic characteristics,comorbidities,biochemical indicators,adrenocorticotropic hormone-cortisol(ACTH-F)levels,and adrenal imaging features and treatment conditions were compared between the two groups.Results(1)General characteristics:Compared with CPA group,PBMAH group had older age at diagnosis and a higher proportion of male patients.(2)Clinical characteristics:Compared with CPA group,PBMAH group had a longer disease duration,a higher proportion of subclinical Cushing's syndrome(CS),and a higher proportion of hypertension,impaired glucose tolerance/diabetes,bone mass reduction or osteoporosis,with higher serum potassium levels,and the differences were statistically significant(P<0.01).(3)Hormone levels:Both PBMAH and CPA groups showed ACTH-F rhythm disorder,significantly increased cortisol levels and suppressed ACTH.Compared with PBMAH group,CPA group had stronger autonomous cortisol secretion ability,manifested by increased midnight serum cortisol(F0:00),16:00 serum cortisol(F16:00),24-hour urinary free cortisol(24 h UFC)levels and lower 8:00 serum ACTH(ACTH8:00)and 16:00 serum ACTH(ACTH16:00)(P<0.01).After low-dose dexamethasone suppression test(LDDST),CPA group showed lower suppression rates of ACTH and cortisol,and higher proportions of paradoxical elevation in serum cortisol and 24 h UFC compared with PBMAH(P<0.01).Conclusions PBMAH has a longer disease course and higher proportions of comorbid metabolic disorders than CPA,mostly manifested as subclinical Cushing's syndrome.CPA has stronger autonomous cortisol secretion ability,with cortisol less likely to be suppressed after LDDST and more obvious paradoxical elevation of cortisol and 24 h UFC.

BackgroundNon-suicidal self-injury （NSSI） represents a prevalent clinical feature among adolescent patients with major depressive disorder. Existing research has suggested that interoceptive awareness might be linked to NSSI behaviors， but investigations into this association among adolescent patients with major depressive disorders remain limited. ObjectiveTo elucidate the correlation between NSSI behaviors and interoceptive awareness in adolescent patients with major depressive disorder， and to identify influencing factors of NSSI behaviors， in order to provide clinical prevention and treatment strategies. MethodsA total of 125 adolescent patients who met the diagnostic criteria for major depressive disorder as outlined in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） were recruited from the Fourth People's Hospital of Hefei from December 2022 to June 2024. These participants were subsequentially categorized into NSSI behavior group （n=60） and non-NSSI behavior group （n=65） based on the presence or absence of NSSI behaviors. Additionally， a control group comprising 40 healthy adolescents was concurrently assembled for comparison. The Hamilton Depression Scale-17 item （HAMD-17） was used to assess the depressive symptoms of adolescent patients with major depressive disorder， and the Multidimensional Assessment of Interoceptive Awareness version 2- Chinese （MAIA-2） was used to evaluate the interoceptive awareness level of all subjects. Pearson correlation analysis was employed to examine the correlation between HAMD-17 scores and MAIA-2 scores. Binary Logistic regression analysis was conducted to identify the influencing factors of NSSI behaviors in adolescent patients. Then the receiver operating characteristic （ROC） curve was drawn to verify the predictive efficacy of MAIA-2 scores for NSSI behaviors in adolescent patients with major depressive disorder. ResultsSignificant differences were identified across six MAIA-2 subscales （noticing， not distracting， not worrying， attention regulation， emotional awareness， body listening） and the MAIA-2 total score among the three groups （F=18.475， 20.631， 6.044， 5.621， 18.456， 12.889， 12.741， P<0.01）. Correlation analysis underscored a notable negative correlation between the MAIA-2 total score and the HAMD-17 total score， as well as its scores on subscales pertaining to weight and cognitive impairment factors（r=-0.315， -0.203， -0.278， P<0.05）. Binary Logistic regression results indicated that longer disease duration （OR=1.112， 95% CI： 1.043–1.206） and higher HAMD-17 total score （OR=2.071， 95% CI： 1.361–3.150） were risk factors for NSSI behavior in adolescents with depressive disorder， while a higher MAIA-2 total score was a protective factor against NSSI behavior in this population （OR=0.580， 95% CI： 0.407–0.828）. The MAIA-2 total score demonstrated a relatively high predictive value for NSSI behaviors in adolescent patients with major depressive disorder （AUC=0.793）. ConclusionNSSI behaviors in adolescent patients with major depressive disorder are closely related to the disease course， severity of depression， and specific interoceptive awareness patterns. Moreover， interoceptive awareness may serve as a predictive indicator for the occurrence of their NSSI behaviors. ［Funded by the National Key Clinical Specialty Construction Project of China； Anhui Provincial Clinical Key Specialty Construction Project； the Hospital-Level Scientific Research Project of the Fourth People's Hospital of Hefei （number， HFSY2022YB07）］

Objective To investigate the molecular mechanism of sulforaphane(Sul)promoting bone marrow stem cells(BMSCs)differentiating into osteoblasts.Methods BMSCs were divided into the control group(without any treatment),induction group(induction of osteogenic differentiation),and induction+Sul group(induction of osteogenic differentiation with the addition of 40 μmol/L of Sul).The adenovirus-shRNA-Mock,-shRNA-TET1,-shRNA-TET2,and-shRNA-TET3 were transfected into BMSCs as the shRNA-Mock group,shRNA-TET1 group,shRNA-TET2 group,and shRNA-TET3 group.BMSCs were cultured in cell culture medium containing osteogenic differentiation induction medium and 40 μmol/L of Sul,and then transfected with adenovirus-shRNA-TET1,-shRNA-TET2,-shRNA-TET3,and-shRNA-Mock as the induction+Sul+shRNA-TET1 group,induction+Sul+shRNA-TET2 group,induction+Sul+shRNA-TET3 group,and induction +Sul+shRNA-Mock group.The mRNA and protein expression levels of Runx2 after BMSCs differentiated into osteoblasts were determined by qPCR and Western blot.The DNA content of Runx2 promoter region bound to Histone H3 after BMSCs differentiated into osteoblasts was determined by chromatin immunocoprecipitation(ChIP).The methylation level of Runx2 promoter region of BMSCs differentiated into osteoblasts was determined by HpaⅡenzyme and MspⅠenzyme digestion combined with qPCR.The degree of BMSCs differentiated into osteoblasts was determined by alizarin red staining.Results Compared with the induction group,the mRNA and protein expression levels of Runx2 in the induction+Sul group were significantly increased(P<0.05);the content of DNA in the Runx2 promoter region bound to Histone H3 was increased(P<0.05),the methylation level of Runx2 promoter region was reduced(P<0.05),and the alizarin red staining score was elevated(P<0.05).Compared with the induction+Sul group,the content of DNA in the Runx2 promoter region bound to Histone H3 in the induction+Sul+shRNA-TET1 group was decreased(P<0.05),the methylation level of Runx2 promoter region was increased(P<0.05),and the alizarin red staining score was decreased(P<0.05).While there was no significant change among the induction+Sul+shRNA-TET2 group,induction+Sul+shRNA-TET3 group,induction+Sul+shRNA-Mock group(P>0.05).Conclusion Sul can promote the differentiation of BMSCs into osteoblasts through promoting DNA demethylation of Runx2 promoter region by TET1.

Objective:To investigate the clinical efficacy of femoral component revision surgery in addressing polyethylene sleeve wear in rotating hinge knee joints.Methods:A retrospective analysis was conducted on 21 patients who underwent treatment for polyethylene sleeve wear in rotating hinge knee joints at the Department of Orthopaedics, the Fourth Medical Center, PLA General Hospital, spanning from August 2008 to April 2023. There were 8 males and 13 females with a median age of 63(38, 76) years. Among them, 11 cases involved the left side, and 10 cases involved the right side. The average body mass index (BMI) was 25.0(22.5, 31.0) kg/m 2, and all cases underwent unilateral knee joint revision. The time interval from receiving the hinge knee joint prosthesis to revision was 10.5(6.0, 17.0) years, with 18 cases undergoing primary revision and 3 cases undergoing revision for the second time. Revision surgery of the femoral component sleeve was performed in all patients due to polyethylene sleeve wear. Visual analogue scale (VAS), range of motion (ROM) of the knee joint, changes in hip-knee-ankle angle (HKA), and Knee Society score (KSS) were collected and recorded to assess the surgical outcomes. Results:All patients were followed up for a median duration of 12.5(11.7, 13.4) months. Preoperatively, the VAS score was 5(3, 7) points, which significantly decreased to 0(0, 1) points at the last follow-up ( Z=5.721, P<0.001). At the last follow-up, the KSS scores decreased from 41.19±13.65 points preoperatively to 79.81±7.80 points, indicating a statistically significant difference ( t=12.560, P<0.001). HKA increased from 174.65°±5.20° preoperatively to 178.71°±2.79°, with a statistically significant difference ( t=5.533, P<0.001). Knee joint ROM increased from 69.05°±34.37° preoperatively to 110.00°±10.12°, also demonstrating a significant improvement ( t=5.960, P<0.001). Notably, patients exhibited knee joint stability with no passive flexion or extension laxity. Conclusion:Femoral component sleeve revision surgery effectively addresses polyethylene sleeve wear in rotating hinge knee joint prostheses, thereby mitigating the substantial loss of bone and soft tissue associated with overall revision procedures. The early postoperative clinical outcomes are promising and indicative of the efficacy of this surgical intervention.
