Its high incidence significantly increases the risk of falls, fractures, disability, and mortality among the elderly, posing a global public health challenge for geriatric health. Insulin-like growth factor-1 (IGF-1), a key cytokine regulating muscle growth, repair, and metabolism, exhibits a progressive decline in serum levels with aging and is closely associated with the onset and progression of sarcopenia in the elderly. This study reviews the research progress of IGF-1 in the diagnosis and efficacy prediction of sarcopenia in the elderly, providing theoretical references for precise diagnosis, treatment, and prognosis assessment of sarcopenia in the elderly.展开更多

文摘To enhance the anti-resistance efficacy of our previously disclosed naphthyl-triazine 5,structure-based drug design strategy was rationally conducted to design a series of novel biphenyl-piperidine-triazinecontaining non-nucleoside reverse transcriptase inhibitors.Remarkably,several of these compounds demonstrated single-digit nanomolar antiviral potency against both wild-type(WT)human immunodeficiency virus-1(HIV-1)and five clinically relevant mutant strains.Among these,compound 11s emerged as the most potent inhibitor,showing remarkable efficacy against WT HIV-1(50%effective concentration(EC_(50))=2 nmol/L)and five mutant strains(EC_(50)=0.003-0.073μmol/L),which was significantly superior to that of compound 5.This optimized derivative demonstrated substantially improved pharmacological properties compared to existing drugs etravirine(ETR)and rilpivirine(RPV),showing a 4-fold reduction in cytotoxicity alongside 6-fold enhancement in selectivity index(50%cytotoxic concentration(CC_(50))=19.69μmol/L,selectivity index(SI)=7438).The compound's metabolic profile revealed exceptional stability,with an elimination half-life(t_(1/2)=41.4 min)more than double that of RPV(t_(1/2)=16.03min).Comprehensive safety evaluation indicated minimal cytochrome P450(CYP)enzymes interference,low cardiac ion channel activity,and no observable acute toxicity,collectively suggesting a reduced risk profile for therapeutic applications.These promising characteristics significantly advance the development potential of biphenyl-piperidine-triazine derivatives as next-generation non-nucleoside reverse transcriptase inhibitors(NNRTIs),offering enhanced efficacy,improved safety,and favorable pharmacokinetic properties for antiretroviral therapy.
文摘Objective:To compare the clinical efficacy and safety of intravitreal injection of faricimab and conbercept in the treatment of diabetic macular edema(DME).Methods:A total of 50 patients diagnosed with DME in our hospital from January 2023 to May 2025 were selected and randomly divided into an observation group and a control group,with 25 cases in each group,using a random number table method.The observation group received intravitreal injection of faricimab,while the control group received intravitreal injection of conbercept.Both groups adopted a loading phase plus maintenance phase treatment regimen.The best-corrected visual acuity(BCVA,expressed in logMAR)and central subfield thickness(CST)of the two groups were compared before treatment and at 1,3,and 6 months after treatment,and the incidence of adverse events during treatment was recorded.Results:The logMAR BCVA in the observation group was lower than that in the control group at 3 and 6 months after treatment(both p<0.05).The CST in the observation group was smaller than that in the control group at 1,3,and 6 months after treatment(all p<0.05).There was no statistically significant difference in the overall incidence of adverse events between the two groups(χ^(2)=0.189,p=0.663).Conclusion:Both intravitreal injections of faricimab and conbercept are effective in improving visual acuity and reducing macular edema in patients with DME,with good safety profiles.However,faricimab demonstrates superior efficacy in the medium to long term(3 and 6 months)compared to conbercept,making it more suitable for long-term treatment of patients with DME.

文摘Objective:To retrospectively evaluate the diagnostic efficacy of traditional MRI and T2 Mapping quantitative imaging technology for knee joint cartilage injury,clarify the differences in diagnostic value of the two imaging methods in different injury grades and different cartilage subregions,and provide evidence-based basis for the accurate diagnosis of clinical cartilage injury.Methods:Clinical and imaging data of 286 patients with knee joint lesions admitted to the Affiliated Hospital of Xiangtan Medicine and Health Vocational College from January 2020 to June 2023 were collected retrospectively.All patients underwent both traditional MRI sequences and T2 Mapping sequences.The knee joint cartilage was divided into 14 subregions.Two senior radiologists independently diagnosed the images of the two imaging technologies using a blind method and recorded the cartilage injury grades.The sensitivity,specificity,accuracy,positive predictive value,negative predictive value,and area under the receiver operating characteristic curve(AUC)of the two technologies for diagnosing cartilage injury were calculated and compared,and the differences in their diagnostic efficacy in different injury grades and different subregions were analyzed.Results:A total of 4004 cartilage subregions from 286 patients were included in the analysis,including 1836 injured subregions and 2168 normal subregions.The overall sensitivity(89.7%),accuracy(91.2%),and AUC(0.946)of T2 Mapping quantitative imaging for diagnosing cartilage injury were significantly higher than those of traditional MRI(76.3%,82.5%,and 0.852 respectively),with statistically significant differences(p<0.001);there was no significant difference in specificity between the two(93.5%vs 90.8%,p=0.062).Subgroup analysis showed that T2 Mapping had the most significant diagnostic advantage in early cartilage injury(Grade 1),with sensitivity(78.5%)33.2%higher than that of traditional MRI(45.3%)(p<0.001).Conclusion:The diagnostic efficacy of T2 Mapping quantitative imaging for knee joint cartilage injury is significantly superior to that of traditional MRI,especially in the detection of early cartilage injury and accurate evaluation of weight-bearing area injury.Data verify its clinical applicability and reliability.It can be used as an important supplementary method to traditional MRI,and is recommended for the early diagnosis,grading evaluation,and clinical follow-up of cartilage injury.
文摘Objective:To investigate the clinical efficacy of electrophysiological therapy under different parameter modes in chronic pelvic pain syndrome(CPPS).Methods:A total of 95patients with CPPS from the Department of Urology,First Affiliated Hospital of Jinan University,were selected and treated with electrophysiological therapy.They were randomly divided into three groups:the fixed-parameter AA7 treatment group,the P2+P4 treatment group,and the precision treatment group(individualized parameter treatment).Pain scores of patients in each group were compared before and after treatment,with a pain score of 0 indicating cure.The cure rate of each group was observed.Results:The average ages of the AA7 group,P2+P4 group,and precision treatment group were 34±14.17 years,35.58±12.57 years,and 35.5±11.27 years,respectively.There was no significant difference in age among the three groups(p>0.05).Before treatment,the pain scores of the AA7 group,P2+P4 group,and precision treatment group were 4.14±1.74,4.64±1.72,and 3.50±1.89,respectively,with no significant differences among the groups(p>0.05).After treatment,the pain scores were 0.71±0.99 for the AA7 group(cure rate:57%),0.49±0.79 for the P2+P4 group(cure rate:67%),and 0.50±0.77 for the precision treatment group(cure rate:64%),with no significant differences among the groups(p>0.05).The cure rates for different pain locations were as follows:83%for lower abdominal pain,74%for perineal pain,62%for dysuria,49%for testicular pain,and 75%for inguinal pain.Conclusion:The pathogenesis of CPPS is complex and diverse,with numerous treatment options and uncertain efficacy,posing significant challenges to clinical practice.This study showed that electrophysiological therapy under different parameter modes significantly reduced pain scores before and after treatment,indicating significant therapeutic effects on CPPS.All three modes demonstrated good cure rates.Individualized precision treatment and fixed-mode P2+P4 or AA7 treatment were safe and effective in CPPS treatment and are worth promoting.Fixed-mode P2+P4 and AA7,due to their easier standardization of parameters and patch modes,reduced the learning curve and had better potential for widespread application.

文摘Chemotherapy-induced diarrhea(CID)is a major concern for cancer patients and is associated with significant morbidity and mortality.Currently,the clinical management of CID is limited.The utilization of antidiarrheal medications,such as loperamide and octreotide,is relatively limited because of their unsatisfactory efficacy and adverse effects.In recent years,traditional Chinese medicine(TCM)has attracted great interest because of its beneficial effect in treating CID,which has multitarget and low-toxicity therapeutic characteristics.TCM exhibits remarkable therapeutic potential in the prevention and treatment of CID.It can alleviate and treat CID by regulating chemical drug metabolism,improving the integrity of the intestinal barrier,stimulating proliferation while suppressing the apoptosis of intestinal epithelial cells,ameliorating oxidative stress and inflammation and regulating bile acids and aquaporins.However,large-scale,randomized,double-blind clinical trials of TCM for the treatment of CID are lacking,and most preclinical experiments have not been translated to clinical trials.Accordingly,this review highlights the clinical efficacy and molecular mechanisms of TCM against CID via PubMed,Web of Science and China National Knowledge Infrastructure and proposes that future research on TCM against CID should focus on strengthening the connection from bench to bed,which may help to comprehensively evaluate the therapeutic potential of TCM against CID.
文摘Sarcopenia in the elderly is a syndrome characterized by age-related progressive loss of muscle mass, decline in muscle strength, and deterioration of muscle function. Its high incidence significantly increases the risk of falls, fractures, disability, and mortality among the elderly, posing a global public health challenge for geriatric health. Insulin-like growth factor-1 (IGF-1), a key cytokine regulating muscle growth, repair, and metabolism, exhibits a progressive decline in serum levels with aging and is closely associated with the onset and progression of sarcopenia in the elderly. This study reviews the research progress of IGF-1 in the diagnosis and efficacy prediction of sarcopenia in the elderly, providing theoretical references for precise diagnosis, treatment, and prognosis assessment of sarcopenia in the elderly.

文摘The brain-gut axis is a bidirectional signal transduction system between the gastrointestinal tract and the central nervous system that integrates neural,endocrine,and immune functions.In recent years,the role of the intestinal flora in regulating neural function and affecting the progression of different neurological diseases has received increasing attention.Akkermansia muciniphila is a mucin-degrading bacterium of the intestinal flora present in the intestinal mucus layer that can regulate host immunity,the intestinal barrier and neuroimmune homeostasis.In recent years,a growing body of literature has suggested that Akkermansia muciniphila may play beneficial roles in nerve injury and regeneration by regulating brain-gut axis signalling.This review comprehensively summarizes the latest research results on the role of Akkermansia muciniphila in neurological diseases such as spinal cord injury,multiple sclerosis,Parkinson’s disease,and Alzheimer’s disease.The mechanisms by which Akkermansia muciniphila regulates inflammatory cytokines,neurotransmitters,and short-chain fatty acids are also highlighted.Various Akkermansia muciniphila-based interventions,such as those involving outer membrane proteins,extracellular vesicles,and pasteurized Akkermansia muciniphila,are discussed,and their therapeutic potential in restoring intestinal homeostasis,alleviating neuroinflammation,and supporting neuronal repair is explored.Although promising results from animal models have been reported,significant challenges remain in translating these findings into clinical practice and therapeutic applications.The differences in Akkermansia muciniphila colonization efficiency,host responses,and intervention strategies in different disease states limit the results of these studies.In addition,Akkermansia muciniphila may exhibit different mechanisms of action in acute and chronic neurodegenerative diseases,and thus more targeted mechanistic studies are needed.Despite these limitations,Akkermansia muciniphila represents a novel and potent pathway for the modulation of the brain-gut axis to support neural repair and functional recovery.By enhancing intestinal barrier integrity and regulating neuroimmunity,Akkermansia muciniphila has broad prospects as a microbial candidate for the treatment of central nervous system diseases.Future research should focus on optimizing the administration method and clinical trials to verify its efficacy,ultimately providing new treatment options in the field of neural regeneration and microbial therapy.
文摘Objective:To evaluate the clinical efficacy of blood-letting cupping combined with manual lymphatic drainage in treating breast cancer-related lymphedema(BCRL)and explore its mechanism of action from both traditional Chinese medicine and modern medical perspectives,providing a scientific basis and novel therapeutic approaches for clinical management of BCRL.Methods:Patients with BCRL admitted to the outpatient and inpatient departments of Hebei University Affiliated Hospital were enrolled.A prospective randomized controlled trial design was adopted,with eligible patients randomly assigned to a treatment group and a control group.The control group received manual lymphatic drainage alone,while the treatment group received manual lymphtic drainage combined with blood-letting cupping therapy.Posttreatment comparisons evaluated upper limb circumference reduction,edema severity grading,and upper limb functional scores.Vital signs and adverse reactions during treatment were recorded for both groups.Statistical software analyzed the data.Results:The treatment group demonstrated significantly greater reduction in upper limb circumference,improvement in edema severity,and higher upper limb function scores compared to the control group(P<0.05).Vital signs remained stable throughout treatment in both groups.No severe adverse reactions occurred in the treatment group;only isolated cases of mild skin itching were reported,which resolved after symptomatic management.Conclusion:The combination of bloodletting cupping and manual lymphatic drainage demonstrates reliable efficacy in treating BCRL,effectively alleviating edema symptoms and improving upper limb function with high safety.Its mechanism may relate to traditional Chinese medicine principles of“unblocking meridians,promoting blood circulation,and resolving stasis”and modern medical concepts of“enhancing local blood circulation,facilitating lymphatic drainage,and reducing inflammatory responses”.
文摘Objective: To evaluate the efficacy of noninvasive positive pressure ventilation (NIPPV) in respiratory support for severe pneumonia. Methods: Data were analyzed from 74 patients with severe pneumonia undergoing respiratory support at our hospital between May 2024 and April 2025.

文摘Traditional Chinese medicine(TCM)is a holistic medical system that classifies and treats diseases based on the concept of patterns.These patterns describe the pathophysiological process of a disease at a specific stage,reflecting both external signs and internal features.TCM patterns are central to pattern differentiation,treatment,clinical practice,and theoretical development in TCM.However,scientific explanation of TCM patterns remains limited because of subjective diagnostic criteria,the absence of a standardized experimental medical system,and unclear biological mechanisms,which restrict the modernization and globalization of TCM.Addressing challenges such as strong subjectivity in diagnosis,lack of standardized experimental systems,and unclear biological mechanisms is necessary to clarify the scientific meaning of TCM patterns and to provide technical approaches for the modernization and globalization of TCM.A strategy focused on“pathogenic factors,genetic predisposition,and disease progression stages”was adopted.This approach included the following:(Ⅰ)constructing disease-pattern integrated biological models with animal models,organoids,and multi-organ chips;(Ⅱ)applying multi-omics technologies,such as spatial omics,single-cell omics,and dynamic metabolic flux omics;(Ⅲ)using artificial intelligence(AI)and big data for data integration and prediction of pattern evolution;and(Ⅳ)validating formula–pattern associations through the“pattern differentiation through formula efficacy”approach.These strategies directly address the main obstacles in TCM pattern research by providing objective,quantifiable,and reproducible methodologies.Constructing disease-pattern integrated models enabled cross-scale research platforms.Applying multi-omics technologies allowed analysis of complex biological bases.AI and big data approaches addressed challenges related to heterogeneous data.The“formula-based pattern differentiation”approach supported precise interventions and the development of new drugs.This interdisciplinary framework advances TCM pattern research by moving from empirical description to objective quantification.By integrating innovative approaches,the study establishes a foundation for systematic,evidence-based TCM diagnosis and treatment,supporting accuracy and promoting international recognition and modernization of TCM.The study shows that combining multi-omics technologies,AI-driven data analysis,and disease-pattern models enables objective quantification of TCM patterns and clarifies their biological mechanisms.

文摘Objective The analgesic effect of acupuncture has been widely accepted.Nevertheless,the mechanism behind its analgesic effect remains elusive,thus impeding the progress of research geared toward enhancing the analgesic effect of acupuncture.This paper investigated the role of acupuncture needle surface textures on acupuncture’s analgesic effect by creating four experimental acupuncture needles with different patterns of surface augmentation.Methods Four types of acupuncture needles with different surface textures(the lined needle,circle needle,sandpaper needle,and threaded needle)were designed.Additionally,the force/torque measurement system used a robot arm and mechanical sensor to measure the force on the needle during insertion and manipulation.To perform acupuncture analgesia experiments,four experimental acupuncture needles and a normal needle were inserted into the Zusanli(ST36)acupoint of rats with inflammatory pain.By comparing the force and torque and the analgesic efficacy of the different acupuncture needles,these experiments tested the role of acupuncture needle body texture on acupuncture analgesia.Results The analgesic effects of different acupuncture needle body textures varied.Specifically,the force required to penetrate the skin with the lined needle was not greater than that for the normal needle;however,the needle with inscribed circles and the sandpaper-roughened needle both required greater force for insertion.Additionally,the torque of the lined needle reached 2×10^(-4)N·m under twisting manipulation,which was four times greater the torque of a normal needle(5×10^(-5)N·m).Furthermore,the lined needle improved pain threshold and mast cell degranulation rate compared to the normal needle.Conclusion Optimizing the texture of acupuncture needles can enhance acupuncture analgesia.The texture of our experimental acupuncture needles had a significant impact on the force needed to penetrate the skin and the torque needed to manipulate the needle;it was also linked to variable analgesic effects.This study provides a theoretical basis for enhancing the analgesic efficacy of acupuncture through the modification of needles and promoting the development of acupuncture therapy.

文摘Objective:To investigate the potential efficacy and safety of Lutai Danshen Baishao granules(LDBG)for treating female melasma associated with kidney deficiency and blood stasis patterns.Methods:A randomized,double-blind,placebo-controlled trial was conducted at the Third Central Hospital of Tianjin,China from March to December 2023.A total of 110 female patients with melasma linked to kidney deficiency and blood stasis were enrolled and treated with either LDBG or a placebo twice daily for 60 days.Efficacy was assessed through measures such as the total melasma area,reduced melasma area,reduction rate of melasma area,melasma color score,Melasma Area and Severity Index(MASI)score,and traditional Chinese medicine(TCM)symptom score scale.Safety assessments included routine blood and biochemical tests.Results:Participants in both groups were aged 52-63 years,with no significant differences.After the 2-month intervention,the total melasma area decreased in both groups;however,a greater reduction was observed in the test group[462.50 mm^(2)(12.81%)vs.100.00 mm2(3.11%),P<.001].Moreover,LDBG treatment significantly reduced the MASI and melasma color scores in the test group(P<.05).The total TCM symptom evaluation score significantly decreased(test group:6.00 vs.placebo group:7.00,P=.001),with significant relief in symptoms such as improvement in dark lips,nails,and waist soreness in the test group,compared with that in the placebo group(P<.05).Within-group comparisons revealed that TCM syndrome was significantly alleviated in the test group(P<.05).Conclusion:LDBG intervention shows promising effectiveness in reducing female melasma and alleviating TCM syndromes.
