Objective:To review systematically the curative effect and safety of levocarnitine combined with Shenmai injection in the treatment of heart failure caused by ischemic cardiomyopathy.Methods:We searched the databases of PubMcd,Cochrane Library,EMbase,CBM,CNKI,WanFang and VIP for randomized controlled trials(RCTs)comparing the effect upon heart failure caused by ischemic cardiomyopathy between levocarnitine combined with Shenmai injection versus standard treatment from the establishment to June 12th,2023.The pooled odds ratio(OR)or mean difference(MD)with 95％confidence interval(CI)were calculated with a Meta-analysis using the Rev-Man 5.4 software.Results:21 eligible literatures were included,involving 2055 patients[mean age(63.86±9.90)years,males 61.27％].Pooled analysis showed that levocarnitine combined with Shenmai injection significantly im-proved the total effective rate(OR=5.04,95％CI 3.78～6.71,P＜0.001),left ventricular ejection fraction(MD=6.10,95％CI 5.18～7.02,P＜0.001),stroke volume(MD=10.64,95％CI 7.42～13.85,P＜0.001),cardiac output(MD=0.85,95％CI 0.74～0.97,P＜0.001),left ventricular fractional shortening(MD=5.27,95％CI 4.16～6.39,P＜0.001),and significantly reduced left ventricular end-diastolic diameter(MD=-5.64,95％CI-7.31～-3.98,P＜0.001)and left ventricular end-systolic diameter(MD=-5.08,95％CI-6.08～-4.09,P＜0.001)than standard treatment.There were no significant differences in the adverse reaction rate be-tween groups(P=0.220).Conclusion:Current research evidence suggests that levocarnitine combined with Shen-mai injection had better efficacy on the heart failure caused by ischemic cardiomyopathy,with good safety.

Objective To investigate the anatomical structure and surface location of the Lieque(LU7)acupoint.Methods Firstly,the anatomical localization descriptions of the Lieque(LU7)acupoint from classical medical literature were reviewed and summarized.A total of 21 participants were recruited from Shandong Provincial Hospital Affiliated to Shandong First Medical University from January to March 2025.A Cartesian coordinate system was established over the Lieque(LU7)region on the right forearm.Following standardized manual pressure stimulation,the coordinates of the participant′s reported acupoint sensations were recorded.Based on surface pressure mapping result,10 participants were arbitrarily selected for acupuncture intervention.Upon elicitation of acupoint sensation,the ultrasound imaging was used for real-time visualization of anatomical spatial relationships between the needle tip and distal radial osseous landmarks.Five red latex-perfused adult upper limb specimens were selected for microdissection of the Lieque(LU7)regions pre-localized via ultrasonography,achieving definitive structural characterization of its anatomical strata.Another 10 participants were arbitrarily selected to find the physical structure of the Lieque(LU7)acupoint using ultrasound,and the similarities and differences of acupoint sensation responses were verified using acupuncture needle insertions into both the demarcated zone and peripheral tissues.Results The descriptions of the localization of the Lieque(LU7)acupoint in ancient books can be summarized as"one and a half cun above the wrist side"longitudinally,and"at the intersection head,between two tendons and two bones in the hollow"transversely.During surface pressure application,the sites of the participant′s elicited acupoint sensation were anatomically concentrated in the proximal depression adjacent to the radiopalmar ridge,specifically at the transitional interface between the extensor pollicis brevis tendon and scaphoid bone.During acupuncture-induced acupoint sensation,ultrasound imaging demonstrated that the location of the needle tip was located within the proximal depression adjacent to the radiopalmar ridge,accompanied by arterial hemodynamic perfusion signals into adjacent osseous interfaces.Microdissection findings revealed perforating branches of the radial artery traversing the cortical bone interface within the Lieque(LU7)acupoint region.Acupuncture stimulation at the proximal depression adjacent to the radiopalmar ridge elicited consistent acupoint sensations in all 10 participants,and the acupoint sensations differed from those of other surrounding tissues.Conclusion The anatomical structure of Lieque(LU7)acupoint is located within the proximal depression adjacent to the radiopalmar ridge,characterized by the presence of"hilus of bone"structure.

Colorectal cancer(CRC)is a malignant tumor formed in the colon or rectum,usually caused by uncontrolled growth and division of normal cells in the body.Cell apoptosis,pyroptosis,and necroptosis are key pathways of cell death in colorectal cancer.The comprehensive treatment strategy includes the synergistic effect of cell death inducers with chemotherapy,immunotherapy,and targeted therapy.Traditional Chinese medicine plays an important role as an adjuvant therapy in regulating cell death.The combination of traditional Chinese and western medicine has shown significant effects in precancerous lesions,improving efficacy,reducing adverse reactions,and reducing drug resistance.Although the research on the mechanism of cell death is not yet sufficient,emphasizing the unique characteristics of traditional Chinese medicine,clarifying the anti-tumor mechanism of traditional Chinese medicine,and achieving modern scientific internationalization of integrated traditional Chinese and western medicine treatment for colorectal cancer have become future research directions.This article will comprehensively review the molecular mechanisms of cell apoptosis,pyroptosis,and necroptosis from the perspective of combining traditional Chinese and Western medicine,as well as their regulatory role in the treatment of colorectal cancer.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To compare the clinical efficacy between microscopic varicocelectomy and laparoscopic varicocelectomy in the treatment of varicocele(VC)with male infertility.Methods:A total of 307 patients who were diagnosed with VC complicated with male infertility and admitted to the Affiliated Hospital of Qingdao University from October 2018 to October 2022 were recruited for retrospective analysis.The patients were divided into the microscopic group(180 cases)and laparoscopic group(127 cases)according to the surgery method.The pre-and postoperative clinical data of these two groups were analyzed,including the degree of dilatation and reflux time of internal spermatic vein,hemodynamic parameters of testicular capsular artery,proportion of progressive motility spermato-zoa(PR),concentration of spermatozoa,proportion of normal morphology sperm,the pregnancy outcome of spouses and the incidence of complications related with surgery within 2 years postoperatively.Results:All the surgeries for the 307 patients in this study were successful.There was no significant difference in operation time,hospitalization time and management expenses between the microscop-ic group and the laparoscopic group(P＞0.05).Compared to the patients in laparoscopic group,the patients in the microscopic group received a better improvement in venous diameter,reflux time of spermatic veins and hemodynamic parameters of testicular capsular ar-tery(P＜0.05).Moreover,the semen analysis showed that the PR,spermatozoa concentration and proportion of normal morphology sperm in the microscopic group were also obviously increased than those in the laparoscopic group(P＜0.05).During the 2-year fol-low-up period,the conception rate of spouses in the microscopic group was 67.2％,while only 47.2％in the laparoscopic group,in which the difference was statistically significant(P＜0.05).Besides,the time-to-pregnancy(TTP)within 2 years postoperatively in the microscopic group was significantly shorter than that in the laparoscopic group(P＜0.05).Meanwhile,the incidence of adverse pregnancy outcomes in the microscopic group was also significantly lower than that in the laparoscopic group(P＜0.05).It is worth mentioned that the spontaneous conception rate of spouses with successful pregnancy in the microscopic group was also significantly higher than that in the laparoscopic group(P＜0.05).Severe complication such as testicular atrophy,bleeding and infection did not appear in both of two groups.However,the incidences of testicular hydrocele and recurrence of VC postoperatively in the laparoscopic group were significantly higher than those in the microscopic group(P＜0.05).Conclusion:Both microscopic varicocelectomy and laparoscopic varicocelectomy can be applied to the management of VC combined with male infertility.But microscopic varicocelectomy showed better clinical efficacy in improving the testicular hemodynamic parameters,semen quality,pregnancy outcome and postopera-tive complications,which is worthy of further clinical applications.

Objective To explore the role and mechanism of RNA m6A methyltransferase Wilms'tumor 1-associated protein(WTAP)in epithelial-mesenchymal transition(EMT)of glioblastoma cells and its association with transcription factor JUNB.Methods(1)Based on the Cancer Genome Atlas(TCGA)and Genotype-Tissue Expression(GTEx)databases,the expression levels of transforming growth factor β(TGF-β),WTAP,and JUNB in glioblastoma multiforme(GBM)and normal brain tissues were analyzed,as well as their diagnostic and prognostic values for GBM.The correlation of TGF-β,WTAP,and JUNB with gliomas of different WHO grades was analyzed using the Chinese Glioma Genome Atlas(CGGA)database.Spearman correlation analysis was performed to assess the correlation between TGF-β and m6A methyltransferases.(2)An EMT model was established in human astrocytoma U87-MG cells through TGF-β1 induction.qRT-PCR and Western blotting were employed to detect the expression levels of WTAP,JUNB,matrix metalloproteinase 2(MMP2),and N-cadherin.The migration capacity of U87-MG cells was evaluated by wound-healing and Transwell assays.An m6A RNA methylation quantification kit(colorimetric)was used to detect RNA m6A methylation modification levels.A stable cell line with low expression of WTAP was constructed to investigate the effects of WTAP knockdown on the migration ability of U87-MG cells,as well as the expression of JUNB.(3)A protein-protein interaction network was constructed using STRING database and GeneMANIA database,followed by gene ontology(GO)and KEGG pathway enrichment analyses to explore the biological processes,molecular functions,cellular components,and signaling pathways potentially involved in TGF-β/WTAP/JUNB.Gene set enrichment analysis(GSEA)was performed on JUNB-related genes to investigate their potential downstream signaling pathways.Results(1)The expression levels of TGF-β,WTAP,and JUNB were significantly higher in GBM(P<0.001),positively correlated with WHO grades of glioma(P<0.001).Glioma patients with high expression of all three genes had shorter overall and disease-free survival(P<0.001).Spearman analysis showed that the expression of TGF-β in GBM was positively correlated with WTAP(r=0.175,P=0.023),but no significant correlation with other m6A methyltransferases(P>0.05).(2)After TGF-β1 treatment,the level of m6A methylation modification of total RNA in U87-MG cells significantly increased(P<0.001).Wound-healing assay and Transwell assay results showed that the migration ability of U87-MG cells was significantly increased after TGF-β1 treatment(P<0.01),while WTAP knockdown significantly reduced the migration ability of U87-MG cells(P<0.01).qRT-PCR and Western blotting results showed that the mRNA and protein expression levels of WTAP,N-Cadherin,MMP2,and JUNB in U87-MG cells were significantly increased after 48 h of TGF-β1 induction(P<0.001),while WTAP knockdown significantly reduced the mRNA and protein expression of JUNB(P<0.001).(3)The TGF-β/WTAP/JUNB-related protein-protein interaction network was constructed,which was primary involved in mRNA modification and EMT.GSEA results showed that JUNB-related signaling pathways were closely associated with glioma malignant progression.Conclusions TGF-β,WTAP,and JUNB are all associated with GBM malignant progression and poor patient prognosis.TGF-β may enhance total RNA m6A modification by promoting the expression of m6A methyltransferase WTAP,and WTAP subsquentaly upregulates transcription factor JUNB,thereby promoting EMT and malignant progression of GBM.

Objective:Systematically review the release status and characteristics of policies related to cross-regional medical insurance settlement policies in China,providing reference for promoting the convenience of medical insurance settlement services and improving management efficiency.Methods:Using content analysis,a two-dimensional framework of"policy objectives-policy tools"was constructed.A total of 127 policy documents were coded and analyzed.Results:Demand-based tools were applied most frequently(43.6%),followed by environmental and supply-based tools.Policy objectives mainly focused on improving service convenience,supported by expanding coverage and ensuring regulatory security.Conclusions:China's cross-regional medical insurance settlement policies have improved service accessibility and strengthened institutional supervision while gradually expanding coverage.However,deficiencies remain in assessment refinement and emergency mechanisms.Greater interdepartmental coordination is needed to enhance regulatory linkage and ensure the safe operation of medical insurance funds.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.
