Hepatocellular carcinoma （HCC） is a malignant tumor with relatively high incidence and mortality rates worldwide， and its therapeutic resistance and recurrence mechanism are closely associated with liver cancer stem cells （LCSC）. This article systematically introduces the biological characteristics of LCSC and their key role in the progression of HCC， reviews the functional characteristics of the specific surface markers （such as EpCAM and CD133） and related signaling pathways （such as Wnt/β-catenin， TGF-β， and STAT3）， elaborates on the interaction between LCSC and tumor microenvironment， and summarizes the latest clinical treatment strategies targeting LCSC and the countermeasure for existing resistance mechanisms. The article points out that LCSC promote tumor development and progression through metabolic reprogramming and immune microenvironment remodeling， and it is proposed to establish a standardized detection system for LCSC specific markers and promote a triple synergistic therapeutic paradigm combining targeted therapy， immune regulation， and traditional chemotherapy， in order to provide new ideas for the clinical intervention of HCC.

Liver cirrhosis is the final stage of the progression of various chronic liver diseases， often accompanied by serious complications and high mortality rates. Recent studies have shown that the interaction between gut microbiota and bile acid metabolism （the gut microbiota-bile acid axis） is closely associated with liver cirrhosis. This article systematically reviews the mechanism of action of the gut microbiota-bile acid axis in the progression of liver cirrhosis， elaborates on the pathological features of liver cirrhosis and its harm to the body， and summarizes the association of the gut microbiota-bile acid axis with the development and progression of liver cirrhosis. It also analyzes the key regulatory role of this axis in the progression of liver cirrhosis and explores its potential application value as a therapeutic target for liver cirrhosis， in order to provide a theoretical basis for exploring more effective clinical intervention methods.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Objective:To explore the predictive value of neutrophil-to-lymphocyte ratio (NLR) and tumor necrosis factor -α (TNF-α) level on the therapeutic effect of transcatheter arterial chemoembolization (TACE) combined with microwave ablation in patients with massive liver cancer.Methods:The medical records of 106 patients with massive liver cancer who underwent TACE combined with microwave ablation treatment in the Affiliated Hospital of Weifang Medical University from February 2020 to February 2023 were retrospectively analyzed. The efficacy was evaluated 6 weeks after surgery, and the patients were divided into remission group and non-remission group according to the therapeutic effect. The levels of NLR and TNF-α in the two groups were detected before surgery, 3 days after surgery and 7 days after surgery. Point two column correlation was used to analyze the relationship between the levels of NLR and TNF-α in different time periods and the therapeutic effect of TACE combined with microwave ablation in patients with massive liver cancer. The receiver operator characteristic (ROC) curve was drawn to analyze the predictive value of NLR and TNF-α levels in different time periods for the therapeutic effect of TACE combined with microwave ablation in patients with massive liver cancer.Results:Six weeks after surgery, out of 106 patients with massive liver cancer, 13 achieved complete remission, 48 achieved partial remission, 20 experienced disease progression, and 25 remained stable. The overall remission rate was 57.55% (61/106). Before surgery, the levels of NLR [ (2.26±0.13) vs. (2.43±0.12), t=6.87, P<0.001] and TNF-α [ (36.20±4.38) pg/ml vs. (42.74±5.74) pg/ml, t=6.66, P<0.001] in the remission group ( n=61) were lower than those in the non-remission group ( n=45), with statistically significant differences. At 3 days after surgery, there were no statistically significant difference in the levels of NLR [ (6.16±3.22) vs. (6.22±3.30), t=0.09, P=0.925] or TNF-α [ (48.84±7.22) pg/ml vs. (49.13±7.34) pg/ml, t=0.20, P=0.840] between the remission group and the non-remission group. At 7 days after surgery, the levels of NLR [ (2.60±0.18) vs. (2.82±0.26), t=5.15, P<0.001] and TNF-α [ (38.20±6.30) pg/ml vs. (45.57±5.79) pg/ml, t=6.16, P<0.001] in the remission group were lower than those in the non-remission group, with statistically significant differences. There were statistically significant differences in NLR and TNF-α levels before surgery, 3 days and 7 days after surgery between the remission group and the non-remission group ( F=82.43, P<0.001; F=54.45, P<0.001; F=76.23, P<0.001; F=15.61, P<0.001). Further pair-to-pair comparison showed that the levels of NLR and TNF-α were higher in both groups 3 and 7 days after surgery than before surgery, but the levels of NLR and TNF-α were lower in both groups 7 days after surgery than 3 days after surgery, with statistically significant differences (all P<0.005). Point two column correlation analysis showed that NLR level, TNF-α level and the efficacy of TACE combined with microwave ablation in patients with massive liver cancer were significantly positively correlated before and 7 days after surgery ( r=0.42, P<0.001; r=0.49, P<0.001; r=0.43, P<0.001; r=0.46, P<0.001). ROC curve showed that the area under the curve (AUC) of NLR and TNF-α alone in predicting the efficacy of TACE combined with microwave ablation in patients with massive liver cancer before and 7 days after surgery was 0.750 (95% CI: 0.656-0.844), 0.788 (95% CI: 0.699-0.877), 0.751 (95% CI: 0.652-0.850), 0.788 (95% CI: 0.700-0.876), respectively. The AUC of combined prediction of NLR and TNF-α before and 7 days after surgery were 0.818 (95% CI: 0.736-0.900) and 0.813 (95% CI: 0.730-0.897), respectively. There were no statistically significant differences in the AUC values of NLR and TNF-α alone or in combination for predicting the therapeutic effect of TACE combined with microwave ablation in patients with massive liver cancer before and 7 days after surgery (all P>0.05) . Conclusions:The levels of NLR and TNF-α before and 7 days after surgery are related to the effect of TACE combined with microwave ablation in patients with massive liver cancer, and the combination of NLR and TNF-α levels before and 7 days after surgery has certain value in predicting the effect of TACE combined with microwave ablation in patients with massive liver cancer.

OBJECTIVE To explore the distribution and drug resistance of the pathogens causing the abdominal(pelvic)soft tissue infections in secondary or above medical institutions of Suzhou so as to provide bases for pre-vention and control of the infections.METHODS The surveillance data of abdominal(pelvic)soft tissue infections that were reported regularly from 58 member institutions of Suzhou from Jan.2020 to Dec.2023 were collected from the regional nosocomial infection surveillance platform by Suzhou nosocomial infection management and qual-ity control center.Totally 26 tertiary hospitals and 32 secondary hospitals were involved.RESULTS Most of the 1178 strains of pathogens were isolated from the tertiary hospitals,the proportion of gram-negative bacteria was the highest;Escherichia coli,Klebsiella pneumoniae and Enterococcus faecium ranked the top 3 species.The constituent ratio of carbapenem-resistant Klebsiella pneumoniae(CRKP)strains the was highest among the mul-tidrug-resistant organisms.The K.pneumoniae and CRKP strains were sensitive to tigecycline;the E.coli strains were highly sensitive to carbapenems,minocycline and piperacillin-tazobactam;Stenotrophomonas maltophilia strains were highly resistant to most of the antibiotics;Enterobacter cloacae strains were highly resistant to ampi-cillin-sulbactam but were highly sensitive to carbapenems;the drug resistance rate of the A.baumannii strains to tigecycline was less than 5％;the drug resistance rate of Pseudomonas aeruginosa strains to ticarcillin-clavulanic acid was highest.CONCLUSIONS The abdominal(pelvic)soft tissue infection is always mixed infections.The pathogens show severe drug resistance.It is necessary to strengthen the surveillance of etiological spectrum and drug resistance and conduct targeted guidance for clinical practice of diagnosis and treatment.

Objective:To explore the effect of evidence-based care model based on the need satisfaction theory in postoperative care of patients with intraspinal tumors.Methods:From August 2022 to August 2024, convenience sampling was used to select 150 patients with intraspinal tumors who underwent surgical treatment at Henan Provincial People's Hospital as research subjects. Patients enrolled from August 2022 to August 2023 were assigned to control group ( n=72), while those enrolled from September 2023 to August 2024 were assigned to intervention group ( n=78). Control group received routine postoperative care for intraspinal tumors, while intervention group received an evidence-based care model intervention based on the need satisfaction theory. Patients were surveyed using the Numerical Rating Scale (NRS), Chinese version of the Connor-Davidson Resilience Scale (CD-RISC), Self-Perceived Burden Scale (SPBS), and Nursing Satisfaction Scale. Two groups of patients were compared in terms of the time to first ambulation after surgery, time to bowel movement recovery, hospital stay, pain levels at 1, 3, and 5 days postoperatively, psychological status, self-perceived burden, and patient satisfaction. Results:After intervention, patients in intervention group demonstrated shorter times to first ambulation after surgery, shorter times to bowel movement recovery, and shorter hospital stays compared to control group. Patients in intervention group had lower NRS scores than those in control group on both postoperative days 3 and 5. Patients in intervention group had higher CD-RISC scores across all dimensions and higher total scores compared to control group. Intervention group scored lower than control group on all dimensions of the SPBS and on the total score. Patients in intervention group reported higher satisfaction with nursing than those in control group. All differences were statistically significant ( P<0.05) . Conclusions:Evidence-based care model based on the need satisfaction theory accelerate postoperative recovery, alleviate postoperative pain, improve psychological status, reduce self-perceived burden in patients with intraspinal tumors, and enhance patient satisfaction.

Naringin is a flavonoid compound with a wide range of biological and pharmacologi-cal activities,which can be used in treating tumor,diabetes,neurodegenerative diseases,cardiovascu-lar diseases,metabolic syndrome,etc.Among them,the application of naringin in cardiovascular diseases has attracted the attention of many re-searchers.This article mainly reviews the role of naringin in cardiovascular disease(regulating blood lipids,anti atherosclerosis,lowering blood pres-sure,inhibiting myocardial hypertrophy,anti myo-cardial infarction,protecting myocardial ischemia/reperfusion injury,reducing myocardial ischemia/reperfusion injury and improving pulmonary arteri-al hypertension),the protective effect on cardiotox-icity,and the signal pathways in cardiovascular dis-ease(PI3K-Akt-mTOR,p-eNOS/p-Akt/p-ERK,miR-126/GSK-3 β/β-Catenin),clinical trials,etc.This pa-per is expected to review the current research sta-tus of naringin in cells and animal models so as to reveal its clinical application prospects and provide reference for further research in related fields.

Objective To explore the epidemiological characteristics and differences in antimicrobial resistance be-tween catheter-associated urinary tract infection(CAUTI)and non-CAUTI of healthcare-associated infection(HAI),and provide scientific basis for precise clinical prevention and control.Methods Based on the regional HAI surveillance platform in Suzhou City,urinary tract infection(UTI)surveillance data reported by 61 member units from January 2020 to December 2024 were analyzed retrospectively.Pathogen distribution,detection rate of multi-drug-resistant organisms(MDROs),and antimicrobial resistance spectrum characteristics of patients in the CAUTI group and non-CAUTI group were compared.Results The incidence of CAUTI in patients in CAUTI group was 0.99‰,the incidence of healthcare-associated UTI in patients in non-CAUTI group was 0.14％.There was statis-tically significant difference in the distribution of UTI pathogens between the two groups(P＜0.05).The patho-gens of the CAUTI group were mainly Gram-negative bacteria(56.1％),with high proportions of Escherichia coli(19.6％)and Klebsiella pneumoniae(15.0％).In the non-CAUTI group,the proportion of Gram-negative bacteria was higher(64.7％).Antimicrobial susceptibility testing results showed that the resistance rates of Escherichia co-li to tobramycin,cephalosporins,and carbapenems in the CAUTI group were all higher than those in the non-CAU-TI group(all P＜0.05).Except for tigecycline,the resistance rates of Klebsiella pneumoniae to other antimicrobial agents in the CAUTI group were all significantly different from the non-CAUTI group(all P＜0.05).The resis-tance rates of Acinetobacterbaumannii to ticarcillin/clavulanic acid,quinolones,most cephalosporins,carbapenems,and aminoglycosides in the CAUTI group were higher than those of the non-CAUTI group(all P＜0.05).The de-tection rates of MDROs were higher in the CAUTI group,especially that of carbapenem-resistant Klebsiella pneu-moniae,accounting for 57.8％.Conclusion There are significant differences in pathogen distribution and antimi-crobial resistance of UTI between the CAUTI group and the non-CAUTI group.It is necessary to establish a re-gional antimicrobial resistance surveillance system for pathogens in UTI,and provide basis for the rational use of an-timicrobial agents in clinical practice.
