This paper explores the research progress of acupuncture for the prevention and treatment of Alzheimer's disease (AD) based on the "kidney-governor vessel-brain" axis. According to the fundamental pathogenesis of AD in traditional Chinese medicine (TCM), which attributes to kidney deficiency, marrow depletion, and impaired mental faculties, as well as the governor vessel's connection between the kidney and brain, the concept of the "kidney-governor vessel-brain" axis is proposed. The theoretical basis of the "kidney-governor vessel-brain" axis is analyzed based on the meridian pathway and physiological functions of the governor vessel, as well as the interdependent and mutually reinforcing relationships among the kidney, governor vessel, and brain. The relationship between AD and the "kidney-governor vessel-brain" axis is elucidated from both traditional medical theories and modern biological perspectives. Integrating clinical and mechanistic research on AD prevention and treatment based on this axis, it is suggested that the "kidney-governor vessel-brain" axis provides valuable insights and references for future research on AD prevention and treatment.

The therapeutic effects of Yueju Pills on depression and cardiovascular diseases have been widely recognized. Previous studies have shown that the drug can significantly improve depressive-like behaviors induced by chronic unpredictable mild stress(CUMS) combined with atherosclerosis(AS). Given the complex pathogenesis of psychocardiac diseases, this study integrated metabolomics and network pharmacology to systematically elucidate the mechanism of Yueju Pills in alleviating depressive symptoms in psychocardiac diseases. The results demonstrate that, after Yueju Pill intervention, the levels of 9 abnormal metabolites in the hippocampus restore to normal ranges, primarily involving key pathways or signaling pathways, including the cyclic adenosine monophosphate(cAMP), mammalian target of rapamycin(mTOR), glycine/serine/threonine metabolism, and aminoacyl-tRNA biosynthesis. In a high-fat diet-induced CUMS ApoE~(-/-) mouse model, Yueju Pills significantly increases adenosine monophosphate(AMP) levels and decreases L-alanine and D-glyceric acid levels in the hippocampus. In conclusion, Yueju Pills exert antidepressant effects by regulating multiple metabolic axes, including glycine/serine/threonine metabolism and the cAMP, mTOR signaling pathways. Network pharmacology predictions reveal that the treatment of CUMS combined with AS by its core active components may be realized through modulating pathways concerning neuroinflammation and synaptic plasticity, including serine/threonine-protein kinase 1(AKT1), mitogen-activated protein kinase 1(MAPK1), and prostaglandin-endoperoxide synthase 2(PTGS2). This study provides a theoretical reference for the clinical application of Yueju Pills in alleviating the depressive symptoms of psychocardiac diseases.

The important studies in the field of extracorporeal life support (ECLS) in 2024 focused on the application of cardiac support technologies in acute myocardial infarction (AMI) with cardiogenic shock (CS): veno-arterial extracorporeal membrane oxygenation (V-A ECMO) has not shown advantages in either short- or long-term outcomes and may increase the risk of bleeding and vascular complications; in contrast, micro-axial flow pumps demonstrate potential in improving mortality. The effects of veno-venous extracorporeal membrane oxygenation (V-V ECMO) combined with prone positioning on severe acute respiratory distress syndrome (ARDS) remain uncertain. The survival benefit of extracorporeal cardiopulmonary resuscitation (ECPR) in out-of-hospital cardiac arrest (OHCA) patients has been further validated. The potential benefits of extracorporeal carbon dioxide removal (ECCO2R) require further investigation. Additionally, new guidelines released in 2024 focus on Neurological monitoring and management during ECMO, as well as the Definition and management of right ventricular injury during veno-venous ECMO. ECMO management requires more refined strategies, including optimized oxygenation targets, anticoagulation, blood transfusion, and weaning strategies to improve patient outcomes.

OBJECTIVE: To identify the risk factors for acute respiratory distress syndrome (ARDS) in geriatric patients following gastrointestinal perforation surgery, and constructed a model to validate its predictive value. METHODS: A retrospective analysis was conducted. The clinical data of geriatric patients (aged ≥ 60 years) after gastrointestinal perforation surgery admitted to the intensive care unit (ICU) of Hebei General Hospital from October 2017 to October 2024 were enrolled. Two groups were divided according to whether ARDS occurred postoperatively, and the differences in each index between the groups were compared. Lasso regression and multifactorial Logistic regression analyses were used to identify independent risk factors for the development of ARDS, and a prediction model was constructed based on these, which was presented using a nomogram. The receiver operator characteristic curve (ROC curve), calibration curve, and decision curve analysis (DCA) were plotted to evaluate the discrimination, accuracy, and clinical practicability of the model. RESULTS: A total of 155 geriatric patients following gastrointestinal perforation surgery were ultimately included in the analysis, among whom 43 developed ARDS, with an incidence rate of 27.7%. There were significantly differences in age, body mass index (BMI), acute kidney injury comorbidity, heart rate, onset time, the duration of surgery, the site of perforation, seroperitoneum, amount of bleeding, shock comorbidity, central venous pressure (CVP), C-reactive protein, and albumin between ARDS and non-ARDS groups. Lasso regression identified nine significant predictors: age, BMI, acute kidney injury comorbidity, onset time, seroperitoneum, shock comorbidity, CVP, hemoglobin, and albumin. Multivariate Logistic regression analysis identified BMI [odds ratio (OR) = 1.310, P < 0.001], hemoglobin (OR = 1.019, P = 0.045), seroperitoneum (OR = 1.001, P = 0.017), and albumin (OR = 0.871, P < 0.001) as independent risk factors for the occurrence of ARDS. A prediction model was constructed based on the above four independent risk factors, and the ROC curve showed that the area under the curve (AUC) of the model for predicting the occurrence of ARDS was 0.885 [95% confidence interval (95%CI) was 0.824-0.946], and internal validation was performed using bootstrap resampling (Bootstrap 500 times), which showed that the AUC value of the model was 0.886 (95%CI was 0.883-0.889). Calibration curves revealed excellent concordance between observed outcomes and model predictions. DCA indicated a high net benefit value for the model, which has good clinical utility. CONCLUSIONS BMI, hemoglobin, seroperitoneum, and albumin were identified as independent risk factors for ARDS in geriatric patients following gastrointestinal perforation surgery. The prediction model constructed using these four indicators facilitates early identification of high-risk individuals by clinicians.

The molecularly imprinted polymers membranes(MIPMs)were prepared for selective adsorption of lamotrigine(LTG)in plasma by surface molecular imprinting technology with polyvinylidenefluoride(PVDF)membranes as supporter,lamotrigine as template molecule,methyl methacrylate as functional monomer,ethylene glycol dimethacrylate as cross-linking agent,azodiisobutyronitrile as initiator and acetonitrile-dimethylformamide(1∶1.5,V/V)as pore-forming agent.The prepared MIPMs were characterized by scanning electron microscope,Fourier transform infrared spectroscopy,Brunaner-emmet-teller measurements,X-ray photoelectron spectroscopy,and thermogravimetric analysis.The adsorption properties of the materials were investigated by kinetic adsorption,isothermal adsorption,selective adsorption,adsorption-desorption and reusability experiments.The results showed that the imprinted layer of LTG was successfully coated on the surface of PVDF,and the materials had uniform particle size.The adsorption capacity and imprinting factor of the MIPMs towards LTG were 3.77 mg/g and 8.97,respectively.The nanomaterials showed fast mass transfer rate(30 min)and good reusability(the adsorption efficiency was 86.66%after 6 cycles),and could be used for the adsorption of LTG in plasma with low matrix interference,recoveries of 86.54%-90.48%and RSD of 1.51%-3.15%(n=5).The proposed LTG MIPMs were demonstrated to be simple and environment friendly,and had high selectivity in rapid separation and extraction of LTG in plasma.

BACKGROUND:Transcranial magneto-acoustical electrical stimulation(TMAES)is a non-invasive,high-precision neurofocused stimulation method based on magneto-acoustic coupling electrical effect,which can regulate the rhythmic oscillation of nerve activity,thereby affecting the brain's movement,cognition and other functions. OBJECTIVE:To explore the effect of TMAES on beta oscillations in the neural circuits of healthy rats and Parkinson's rats. METHODS:(1)Animal experiments:Twenty-four Wistar rats were randomly divided into four groups(n=6 per group).The rats in the normal control group received no intervention,while those in the normal stimulation group received TMAES(the average spatial peak pulse intensity:13.33 W/cm2,fundamental frequency:0.4 MHz,the number of fundamental wave cycles:1000,and pulse frequency:200 Hz).The model control group and model stimulation group were established by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine.After successful modeling,the rats in the model control group received sham TMAES stimulation in the prefrontal cortex,and those in the model stimulation group received TMAES in the prefrontal cortex,and the duration of stimulation was 2.0 minutes per day.After an interval of 8-10 minutes,the local field potential signals of rats were collected during the execution of T-maze test and the correct rate of behavior was recorded at the same time to compare and analyze the time-frequency distribution of local field potential signals and behavioral differences among the groups.The stimulation experiment and T-maze test were stopped when the correct rate of rats was higher than 80%for 3 consecutive days.(2)Modeling and simulation experiments:The cortical-basal ganglion circuit model under TMAES was established,and the ultrasonic emission period(5,10,20 ms),ultrasonic emission duty cycle(30%,50%,90%)and induced current density(20,50,100 μA/cm2)were changed respectively to compare the power spectral density values of beta oscillations in healthy rats and Parkinson's rats under different stimulation parameters. RESULTS AND CONCLUSION:(1)Animal experiments:The spatial learning ability of the rats in the normal control group was stronger than that of the model control group(P＜0.001),the spatial learning ability of the rats in the normal stimulation group was stronger than that of the normal control group(P＜0.05),and the spatial learning ability of the rats in the model stimulation group was stronger than that of the model control group(P＜0.01).The distribution of beta oscillation energy in the normal control group was more concentrated,and the beta oscillation signal energy was reduced in the normal stimulation group compared with the normal control group.The beta oscillation energy was widely distributed and the energy value was significantly higher in the model control group and the model stimulation group than the normal control and normal stimulation groups.Moreover,the beta oscillation signal energy in the model stimulation group was significantly lower than that in the model control group.(2)Modeling and simulation experiments:the peak power spectral density of the beta band of healthy rats without stimulation(30 dB)was significantly lower than that of Parkinson's rats(55 dB).The power spectral density value generally decreased after stimulation.The peak power spectral density in the beta band was positively correlated with the ultrasonic emission period and negatively correlated with the induced current density.In addition,the peak power spectral density value was the lowest when the duty cycle of ultrasonic emission was 50%.These findings indicate that TMAES suppresses beta oscillations in healthy and Parkinson's disease rats,thereby improving motor function and decision-making cognitive function in rats.

Abstract In recent years, the prevention and treatment of eye diseases in children has become one of the worldwide recognized public health issues. Both genetic and environmental factors can influence the development of offspring visual systems, leading to abnormal vision acuity such as refractive errors, strabismus, and nystagmus. With the aim of elucidating the influencing factors and mechanisms of early life adverse exposures on offspring vision outcomes, the article summarizes the research on exposure in early life and visual acuity in offspring from different perspectives, including tobacco exposure during pregnancy, exposure to microelements, gestational diabetes, gestational hypertension, and drug abuse during pregnancy, so as to provide scientific evidence for the development of more effective strategies to prevent and control eye diseases in children and adolescents.

Objective:To introduce a surgical technique of " short distances and multi-segment" buried-guiding suture method and its effects in the surgery of early descent of prosthesis after augmentation mammaplasty.Methods:From August 2019 to January 2022, 15 cases of early descent of prosthesis after augmentation mammaplasty due to axillary approach breast augmentation for micromastia were admitted to the Plastic Surgery Department of Sichuan Provincial People′s Hospital, aged 23-35 years (27.3±3.6) and duration of dislocation from 16 to 35 days (23.8±5.8). There were 12 patients showed unilateral prosthesis drops and 3 patients showed bilateral prosthesis drops. " Short distances and multi-segment" buried-guiding suture method was used to solve the problem, i. e., 2-0 non-absorbable sutures were used to eliminate the lower pole of prosthetic cavity with " short distances and multi-segment" sutures. The distance from the nipple to the midline of the sternum, the distance from the sternotomy to the nipple, the distance from the nipple to the inframammary fold and the distance from the midclavicular point to the inframammary fold were measured bilaterally before and after surgery, and statistical analysis was performed to evaluate the efficacy of the " short distances and multi-segment" buried-guiding suture method for early descent of prosthesis after breast augmentation.Results:All incisions healed by first intention without complications such as hematoma, infection, or scar hyperplasia. 15 patients were followed up for 6-12 months (8.0±1.9). 14 patients were satisfied with the results after surgery, and 1 patient received satisfactory results after secondary surgery. The distance from nipple to inframammary fold was shortened by 0.8-1.4 cm after surgery (1.2±0.2), and the distance from mid-clavicle to inframammary fold was shortened by 1.0-1.6 cm (1.3±0.4), and the differences were statistically significant as compared with the values before surgery ( t=31.17, P<0.05; t=33.78, P<0.05). After surgery, the change in the distance from nipple to sternal was 0.1-0.3 cm (0.16±0.10), and the change in the distance from sternal notch to nipple was 0-0.2 cm (0.12±0.10), and the differences were not statistically significant ( P>0.05). Conclusions:With the advantages of simple operation, little trauma and no additional incision, the " short distance and multi-stage" buried-guiding suture method in the surgery of early descent of prosthesis after augmentation mammaplasty is worthy of clinical application.

AIM:To investigate the mechanism of chronic stress-induced myocardial injury in atherosclerotic(AS)mice.METHODS:Eight-week-old SPF-grade male ApoE-/-mice and C57BL/6J mice used in this study.The mice received dietary intervention for 10 weeks followed by pathological examination to test the successful AS modeling.After AS establishment,the mice were exposed to chronic unpredictable mild stress(CUMS)for 6 weeks and then divided into five groups:control,CUMS,AS-regular diet(AS-r)+CUMS,AS-high-fat diet(AS-h),and AS-h+CUMS.During CUMS,open-field test and sucrose preference test were performed on mice in all groups.Blood lipids were characterized using an automatic biochemical analyzer.Hematoxylin-eosin(HE)and oil red O staining were performed to evaluate pathological changes in the aortic root.Cardiac function was assessed using echocardiography.The serum concentration of myocardial injury markers and ATP content was detected by ELISA.Transmission electron microscopy was employed to observe the ul-trastructure of myocardial mitochondria.Myocardial mitochondrial oxygen consumption rate was determined using the Oxy-graph-2k high-resolution respiratory energy metabolism analyzer.Western blot was conducted to quantify the expression of B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),and cleaved caspase-3.RESULTS:compared with the Control group,the total distance traveled,the number of entries into the central area,and the sucrose preference rate were significantly decreased in all CUMS groups(P<0.05).All AS groups exhibited varying levels of lipid deposition and endo-thelial damage in the aortic root,along with a significant reduction in cardiac function(P<0.05)and varying degrees of myocardial injury(P<0.05).In the AS-h+CUMS and AS-r+CUMS groups,myocardial mitochondrial structure was signifi-cantly disrupted.ATP content was significantly reduced(P<0.05),and the rates of oxygen consumption associated with mitochondrial respiratory chain complex I,mitochondrial respiratory chain complexes I+II,and the maximum respiratory capacity of the electron transport system were all significantly decreased(P<0.05).Moreover,the protein levels of Bax and cleaved caspase-3 were significantly increased(P<0.05),while that of Bcl-2 protein was significantly decreased(P<0.05).CONCLUSION:Chronic stress triggers mitochondrial non-steady-state load by disrupting myocardial structure and energy metabolism in AS mice,promoting myocardial cell apoptosis and myocardial injury.

Objective To identify the risk factors for postoperative delayed weaning in patients with intracerebral hemorrhage and to establish a predictive model.Methods A retrospective study was conducted on 207 patients who underwent surgery for intracerebral hemorrhage at the intensive care unit(ICU)of Peking University People's Hospital from October 2014 to October 2021.Utilizing the 2007 European Respiratory Society consensus criteria,patients were divided into delayed weaning group(n=66)and non-delayed weaning group(n=141).The demographic and operation-related conditions of the two groups were compared.Multiple logistic regression analysis was employed to identify the risk factors for delayed weaning,and a risk assessment nomogram was constructed and validated.Results Compared with the non-delayed weaning group,the delayed weaning group exhibited a significantly higher proportion of comorbid cardiovascular and cerebrovascular diseases,a lower Glasgow coma scale(GCS)score on admission,a greater incidence of preoperative brain herniation,a higher proportion of patients undergoing emergency surgeries and decompression craniotomies,and higher postoperative APACHE Ⅱ score,GCS score,incidence of atelectasis,weaning failure rate and mortality rate,and longer ICU stay and hospital stay(P<0.05).Multiple logistic regression analysis indicated that emergency surgery,low postoperative oxygenation index,low postoperative score of highest GCS before weaning,and incidence of atelectasis were independent risk factors for postoperative delayed weaning(P<0.05).A nomogram predictive model was established using these four predictors,with an area under the receiver operating characteristic(ROC)curve(AUC)of 0.855(95%CI 0.804-0.907),and the Hosmer-Lemeshow test showed good model fit(P=0.659).Conclusions Postoperative delayed weaning is associated with extended durations of mechanical ventilation,ICU stay,and hospital stay,as well as an increased risk of weaning failure and in-hospital mortality rate.The nomogram model provides valuable insights for the early recognition of patients at high risk for postoperative delayed weaning,thereby facilitating timely adjustment in ventilation management strategies.
