OBJECTIVE To investigate the mechanism of isochlorogenic acid A against hepatocellular carcinoma based on the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway and multi-omics technology. METHODS The invasion rate and migration rate of human hepatocellular carcinoma HepG2 cells after 48 h of intervention with 0 （control group）， 0.25 and 0.5 mg/mL isochlorogenic acid A were examined； mRNA expression of DEP domain-containing mTOR-interacting protein （DEPTOR）， the protein expressions of mTOR， PI3K and phosphatase and tensin homologue deleted on chromosome ten （PTEN）， as well as the phosphorylation level of Akt protein were determined in the cells. Metabolomics analysis was performed using liquid chromatography-tandem mass spectrometry， and differential metabolites were screened and subjected to Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis； transcriptomics monitoring was conducted by RNA sequencing， and differentially expressed genes were screened and subjected to gene ontology （GO） and KEGG pathway enrichment analyses. RESULTS Compared with the control group， intervention with 0.25 and 0.5 mg/mL isochlorogenic acid A for 48 h significantly inhibited the invasion rate and migration rate of HepG2 cells， significantly up-regulated the mRNA expression of DEPTOR and the protein expression of PTEN， and significantly down-regulated the protein expression of PI3K and the phosphorylation level of Akt protein （except for 0.25 mg/mL isochlorogenic acid A） （ P ＜0.05）. A total of 304 differential metabolites and 212 differentially expressed genes were screened by multi-omics analysis. KEGG pathway enrichment analysis suggested that isochlorogenic acid A regulated key signaling of HepG2 cell growth mainly by inhibiting the PI3K/Akt signaling pathway， synergizing with metabolic reprogramming such as mTOR signaling pathway， ferroptosis， pentose phosphate pathway and purine/pyrimidine metabo lism. CONCLUSIONS The anti-hepatocellular carcinoma effect of isochlorogenic acid A is associated with the blockade of abnormal activation of the PI3K/Akt/mTOR signaling pathway. In addition， it may also be related to the inhibition of the pentose phosphate pathway and purine/pyrimidine metabolism， as well as the induction of ferroptosis，etc.

Cartilage degeneration stands as the main pathological hallmark of joint diseases such as osteoarthritis(OA),characterized by the degradation of cartilage matrix,abnormal cell function,and disruption of structural integrity.This series of changes poses a severe threat to patients' quality of life.The significant impact of mechanical stimuli on cartilage health and function has long been widely acknowledged,and research on its underlying mechanisms has become relatively systematic and in-depth.However,the specific pathways in which mechanical stimuli affect cartilage,as well as the hidden laws and intrinsic mechanisms behind them,are still in the process of continuous exploration,gradual revelation,and ongoing refinement.This article reviews the research progress in the field of mechanical stimuli and articular cartilage in 2024,indicating that it demonstrated characteristics of greater diversity in research subjects,broader perspectives,and more innovative techniques,further expanding our understanding of the role of mechanical factors in cartilage degeneration.The mechanical regulation-based therapeutic strategies are also explored,such as exercise therapy,biomechanical correction,chemical drug therapy,acupotomy therapy,and tissue engineering,providing theoretical foundations and practical directions for the prevention and treatment of degenerative joint diseases.Future research should concentrate on the integration of multi-scale and multi-perspective mechanisms as well as clinical translation to promote the application of precision medicine in the field of cartilage degeneration.

Objective:Multivariate logistic regression analysis was performed to analyze the risk factors for intensive care unit-acquired weakness (ICU-AW) in critically ill patients.Methods:A total of 220 critically ill patients who were admitted to Intensive Care Unit, The First Hospital of Jiaxing from January 2020 to January 2022 were included in this study. The incidence of ICU-AW was recorded. Univariate analysis was conducted to investigate the factors related to ICU-AW, while multiple logistic regression analysis was performed to identify independent risk factors for ICU-AW in critically ill patients.Results:Among the 220 critically ill patients, 64 developed ICU-AW, resulting in an incidence of 29.1% (64/220). There were no significant differences in sex, age, history of alcoholism, history of smoking, marital status, hypertension, diabetes, or use of glucocorticoid (methylprednisolone sodium succinate for injection) between the ICU-AW group and the non-ICU-AW group (all P > 0.05). The proportion of patients with sepsis in the ICU-AW group was higher than that in the non-ICU-AW group [46.9% (30/64) vs. 15.4% (24/156)]. The proportion of patients who were immobilized in the ICU-AW group was higher than that in the non-ICU-AW group [89.1% (37/64) vs. 64.1% (100/156)]. The use of nerve blocker (vecuronium bromide for injection) was more prevalent in the ICU-AW group than that in the non-ICU-AW group [57.8% (37/64) vs. 23.1% (36/156)]. The Acute Physiology And Chronic Health Evaluation Ⅱ score in the ICU-AW group was higher than that in the non-ICU-AW group [16 (11, 23) vs. 12 (8, 17)]. The duration of mechanical ventilation in the ICU-AW group was longer than that in the non-ICU-AW group [8 (4, 13) days vs. 4 (3, 6) days]. The length of hospital stay in the ICU-AW group was longer than that in the non-ICU-AW group [10 (7, 17) days vs. 7 (5, 11) days]. The blood lactate level in the ICU-AW group was higher than that in the non-ICU-AW group [2 (1, 2) mmol/L vs. 1 (1, 2) mmol/L]. All differences were statistically significant ( χ2 = 24.30, 13.83, 24.70, Z = 3.83, 4.59, 3.97, 2.70, all P < 0.05). The results of the univariate analysis, when included in the multivariate logistic regression analysis, showed that sepsis, immobilization, duration of mechanical ventilation, blood lactate level, and Acute Physiology And Chronic Health Evaluation Ⅱ score were independent risk factors for ICU-AW (all P < 0.05). Conclusions:The incidence of ICU-AW is high and the risk factors for ICU-AW are complex. Therefore, targeted control of high-risk factors should be actively performed to prevent and treat ICU-AW.

A ketogenic diet(KD)refers to an eating pattern designed to achieve a low-calorie content,minimum carbohydrate intake,high-fat consumption,and standard protein levels.A ketogenic diet is used in clinical practice to treat conditions including heart disease,diabetes,obesity,autism,glioblastoma,and other cancers.Although a ketogenic diet has not been recommended for any neurological disorders except epilepsy,extensive recent research suggests that such a diet may have a neuroprotective effect and may thus represent a new dietary therapy for the treatment of Parkinson's disease(PD).In this review,we discuss in detail the mechanisms responsible for the neuroprotective effects of a ketogenic diet in Parkinson's disease,with the aim of providing references for future clinical and experimental studies.

Objective To investigate the prognostic value of the platelet-to-lymphocyte ratio(PLR)at different early time points in adult patients undergoing veno-arterial extracorporeal membrane oxygenation(VA-ECMO).Methods A retrospective study was conducted,selecting 55 adult patients who underwent VA-ECMO treatment at the First Hospital of Jiaxing from June 2020 to October 2022 as the study subjects.Then,the patients'gender,age,past history[including hypertension,diabetes,heart disease,chronic obstructive pulmonary disease(COPD)],and the reason for extracorporeal membrane pulmonary oxygenation(ECMO)adjuvant therapy[including severe myocarditis,acute myocardia infarction,in-hospital and out-of-hospital cardiac arrest,severe closed craniocerebral injury,severe pneumonia,pelvic fracture,other(pulmonary embolism,electrocution,traumatic hepatic rupture,post-partum hemorrhage,severe acute pancreatitis,crush syndrome)],acute physiology and chronic health evaluationⅡ(APACHEⅡ),sequential organ failure assessment(SOFA)at the time of admission,and ECMO peripheral blood tests[creatinine,alanine aminotransferase(ALT),aspartate aminotransferase(AST),blood lactate acid(Lac),white blood cell count(WBC),neutrophil count(NEU),lymphocyte count(LYM),hemoglobin(Hb),and platelet count(PLT)]and the last time prior to ECMO assistance,24 hours prior to the occurrence of acute kidney injury(AKI),and 24 hours after the occurrence of AKI.PLR levels at 24 hours ECMO,and the proportion of continuous renal replacement therapy(CRRT).The patients were divided into a death group and a survival group based on their 30-day prognosis and further categorized into a CRRT group and a non-CRRT group based on whether CRRT was administered.Clinical indicators of patients with different prognosis and the differences in PLR levels between CRRT and non-CRRT groups were compared.Logistic regression analysis was used to identify independent risk factors affecting the 30-day prognosis of VA-ECMO patients.The receiver operator characteristic(ROC curves)were plotted to evaluate the prognostic predictive value of each risk factor.Results Compared to the survival group,the death group had significantly higher APACHEⅡscores,SOFA scores,LYM and proportion receiving CRRT[APACHEⅡscore:34.00(28.50,36.00)vs.25.00(14.75,34.00),SOFA score:5.00(4.00,6.50)vs.3.00(2.00,5.25),LYM(×109/L):3.40±1.97 vs.2.24±2.11,proportion receiving CRRT:91.30%(21/23)vs.62.50%(20/32)],and a significantly lower level of the last PLR prior to ECMO adjuvant[30.00(21.06,48.17)vs.58.82(41.80,145.72)],and the differences were statistically significant(all P<0.05).Logistic regression analysis showed that the levels of the last PLR before ECMO assistance[odds ratio(OR)=0.965,95%confidence interval(95%CI)was 0.938-0.993,P=0.013],APACHEⅡscore at the time of admission(OR=1.121,95%CI was 1.018-1.234,P=0.020),and CRRT(OR=7.734,95%CI was 1.042-57.401,P=0.045)were independent risk factors affecting the prognosis of the VA-ECMO patients at 30 days after adjuvant;the ROC curve analysis showed that APACHEⅡscore,CRRT and the last PLR level before ECMO assistance had a predictive value for the prognosis of VA-ECMO patients 30 days after assistance,in which the APACHEⅡscore+the last PLR level before ECMO assistance had the greatest predictive value in predicting the prognosis of the patients,with area under the curve(AUC)of 0.846,with a sensitivity of 62.5%and a specificity of 95.7%.Higher early PLR levels were associated with better prognosis.In the CRRT group,PLR levels at 24 hours before ECMO initiation,24 hours before AKI onset,and 24 hours after AKI onset were significantly lower than those in the non-CRRT group(all P<0.05).Conclusion Early PLR levels and CRRT administration have significant predictive value for the prognosis of patients undergoing VA-ECMO therapy.

With the development of the economy in our country,trauma has already become a major medical burden in society,traffic injury has already become a major type of trauma,and the trauma of lower limbs is relatively much more.Since patients with lower extremity trauma have limited mobility,postoperative dressing changes need to be done at the bedside.At present,in the process of lower limb dressing change,it is necessary for family members or medical staff to help elevate the affected limb,which is unstable and difficult to adhere to.The dressing change process not only increases the pain of patients,but also affects the sight line and comfort of medical staff during operation,resulting in incomplete wound exposure and affecting the effect of dressing change.The washing solution and disinfectant in the dressing change process are easy to contaminate the sheets,which increases the difficulty of ward management.This dressing change method is unscientific,irregular and inconvenient to operate.Therefore,the medical staff of department of emergency of the First Hospital of Jiaxing City developed a mobile treatment vehicle for leg care for debridement and dressing change of patients with lower limb trauma,this device has been granted the National Utility Model Patent of China(patent numbeer:ZL 2021 2 0647636.0),which makes bedside debridement and dressing change more scientific,convenient and normative.The utility model relates to a mobile treatment vehicle for leg care,which is composed of a base,a support seat,a leg support plate,a support rod,a fixed plate and a smart trash can.The angle of the leg support plate can be adjusted 360 °by loosening the bolt,and the height can be adjusted by sliding up and down.Adequate rotation flexibility and high adjustment space can effectively solve problems of bedside debridement and dressing change for patients with lower limb trauma,provide scientific,simple and operable auxiliary tools for trauma medical staff,improve the comfort of patients and operators,and improve the quality of ward management in emergency trauma ward.

Bedridden patients with cardiopulmonary diseases,elderly long-term bedridden patients,and certain postoperative patients require elevation of their lower limbs to a position above the heart.Traditionally,this is achieved by placing items such as clothing,blankets,or soft objects like leg pads under the lower limb as cushions.However,this method can lead to uneven force distribution on the patient's legs,potentially causing vascular compression and discomfort.To address these issues,the medical staff of department of brain surgery of the Second People's Hospital of Tongxiang City had developed a multi-functional foot pad device incorporating height adjustment,pressure dispersion,and heating functions,based on biomechanical principles.This device has been granted a National Utility Model Patent of China(patent number:ZL 2021 2 3217248.8).The device consists of a cushion plate,a backing plate,a raised block,a rotating shaft,a fixed shaft,a support frame,a chute,a footrest,a gaiter strap,a connecting belt,an extension plate,a drive motor,and a power cord.It allows for angular adjustments ranging from 15°-45° through the use of a rotating backing plate and a chute-supported frame.The arc-shaped footrest,designed ergonomically,and an intelligent temperature control system enable precise adaptation to individual anatomical characteristics.The usage procedure involves placing the adjustable foot pad on a flat bed,positioning the patient's leg in the footrest,securing it with the gaiter strap,adjusting it to a comfortable height,activating the intelligent temperature control system for heating,and promoting limb blood circulation.This device offers an innovative solution for preventing lower extremity deep vein thrombosis(LE-DVT)by employing a multi-dimensional intervention strategy that combines mechanical prevention with physical therapy effects.The adjustable heating foot pad is easy to operate,provides comfort and convenience,and reduces complications such as LE-DVT formation,thereby alleviating the economic burden on patients,enhancing quality of life,and increasing patient and family satisfaction.It is highly suitable for clinical application.

OBJECTIVE To construct a prevention and control index system suitable for stomatology outpatient de-partment of general hospital,so as to provide a theoretical basis for risk assessment of stomatology outpatient de-partment,and to provide an evidence-based basis for precise prevention and control.METHODS Based on the methods of literature research,literature quality evaluation and brainstorming,a draft index of the prevention and control of the general hospital's oral outpatient department was constructed,and the index system for the preven-tion and control in the stomatology outpatient department of a general hospital was finally established through re-search group discussion,content analysis and expert consultation.The three-level indicators in the index system were incorporated into the risk points of risk assessment,the failure mode and effects analysis were applied to con-duct the risk assessment,and the intervention measures and rectification cycles were formulated and implemented in clinical practice for the risk points with risk priority number(RPN)greater than 125.Based on the established index system and risk points with RPN＞125,the hospital infection prevention and control checklist for stoma-tology outpatient was developed and regularly checked in the clinic.After the rectification was completed,the risk points were evaluated again,and the RPN values were compared before and after the risk control.RESULTS The recovery rate of expert consultation questionnaire was 100.00％,and the average expert authority coefficient was 0.84.The consistency ratio(CR)for the first-level indicators was 0.0499,and the consistency ratio(CR)of the second-level indicators was 0.0000-0.0790,which was less than 0.1,and the consistency was acceptable.Final-ly,a hospital infection prevention and control index system was established,comprising 5 first-level indicators,7 second-level indicators and 23 third-level indicators.The improved key control risk points were evaluated again,and the RPN values before and after comparing the risk control were reduced and＜125,indicating that the im-provement measures were effective.CONCLUSION The evaluation system of prevention and control for the stoma-tology outpatient department of a general hospital established in this study is reliable,scientific and practical,and the improvement measures of risk assessment before and after the control of risk points are effective,which pro-vides evidence-based basis for risk assessment and precise prevention and control in the stomatology outpatient de-partment of general hospitals.
