Objective:To explore the acupoint selection law of acupuncture and moxibustion in the treatment of broca aphasia after stroke.Methods:RCT articles about acupuncture and moxibustion treatment for broca aphasia after stroke were retrieved from CNKI, VIP, Wanfang Data, China Medical Journal Full-text Database, SinoMed, PubMed, Web of Science and Embase database from the establishment of the databases to May 31, 2024. Excel 2021, SPSS Statistics 27.0, SPSS Modeler 18.0 and Cytoscape 3.9.1 software were used to analyze the frequency of acupoint, clustering, association rules and core co-occurrence network.Results:A total of 87 articles were included, involving 100 acupuncture and moxibustion prescriptions and 101 acupoints/acupoint area, involving 6 types, including Lianquan (CV 23) (35 times), Jinjin (EX-HN12) (35 times) and Yuye (EX-HN13) (34 times). The selected acupoints were mainly distributed in the head, face, neck and lower limbs, and the meridians were mainly Governor Vessel and Conception Vessel; the specific acupoints were mainly original acupoints, followed by collaterals acupoints, and scalp acupuncture was used most frequently in special acupuncture (88 times). According to the clustering analysis of high-frequency acupoints/acupoint area, there were five effective groups, such as "Jinjin (EX-HN12)-Yuye (EX-HN13)-Lianquan (CV 23)-Baihui (GV 20)-Yamen (GV 15)". The core co-occurrence network analysis showed that the acupoints used most frequently were Lianquan (CV 23) and Jinjin (EX-HN12), and the highest correlation between the two acupoints was Jinjin (EX-HN12)-Yuye (EX-HN13).Conclusions:Acupuncture and moxibustion for the treatment of broca aphasia after stroke is often based on "awakening the brain as the outline, benefiting the marrow as the foundation, and resuscitation". Under the guidance of the theory of Zang-fu meridians and collaterals, through dredging the meridians and collaterals, tonifying the brain and opening and closing the sound, the recovery of language function can be achieved.

Guided by the pathogenesis of"structure-activity imbalance of lung collaterals",this paper proposes that structure-activity imbalance of lung collaterals is the initial factor of idiopathic pulmonary fibrosis(IPF)and elucidates the pathogenesis of abnormal changes in biomechanical properties of IPF.It is postulated that the changes of biomechanical properties of lung tissue are closely related to the injury of lung qi collaterals,the abnormal mechanical stress are closely related to the injury of lung blood collaterals,and the biomechanical response of intrapulmonary resident cells is closely related to the structure-activity imbalance of lung collaterals,which ultimately leading to abnormal increase in lung tissue stiffness and progressive scarring formation in lung tissue.Integrating traditional pathogenesis concepts with microscopic pathological changes,and the in-depth exploration of the correlation between the structure-activity imbalance of lung collaterals and the biomechanical properties of IPF can provide direction for exploring IPF medical-engineering cross research,which are of great significance for enriching the syndrome and treatment system of lung collateral diseases.

Objective The aim of this study is to systematically analyze the therapeutic mechanisms of Wuzi Yuye Decoction in diabetic oligoasthenozoospermia based on network pharmacology and animal experiments.Methods Active components and therapeutic targets of Wuzi Yuye Decoction were screened by integrating multiple databases,and their inter-section with diabetic oligoasthenozoospermia-related targets was obtained.Common targets were identified using the Venny platform,and protein-protein interaction(PPI)networks were constructed via the STRING database.And key targets were screened through topological analysis with Cytoscape.Gene Ontology(GO)functional enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analyses were performed using the DAVID platform.A mouse model of diabetic oligoasthenozoospermia was established by high-fat diet combined with streptozotocin induction,followed by intervention with Wuzi Yuye Decoction.Body weight,testicular index,and sperm quality were assessed,while histopathological changes were evaluated by HE staining and transmission electron microscopy(TEM).In addition,ELISA,oxidative stress assays and Western blot were used to verify the changes in key pathway-related proteins.Results A total of 36 common targets were identified,including key nodes such as TNF,IL6 and IL1B.Enrichment analysis indicated that these targets were sig-nificantly involved in inflammatory responses,oxidative stress,autophagy-apoptosis regulation and reproduction-related pathways.Animal experiments confirmed that Wuzi Yuye Decoction markedly improved testicular mass and sperm motility in diabetic mice,reduced the levels of AGE,TNF-α,IL-6 and IL-1β in testicular tissues,alleviated oxidative stress damage,and restored autophagic flux and blood-testis barrier function by inhibiting the RAGE/NF-κB/mTOR signaling axis.Conclusion Wuzi Yuye Decoction improves the pathological progression of diabetic oligoasthenozoospermia by synergistically modulating multiple targets,including inflammation inhibition,antioxidant effects,autophagy regulation,and related pathways.

Objective:To evaluate the role of tubulin tyrosin ligase like-6 (TTLL6)-mediated microtubule polyglutamylation and Spastin(a microtubule cleaving protein)-induced excessive microtubule cleavage in the developmental impairment of dendritic spines in neonatal mice following repeated sevoflurane anesthesia, by utilizing TTLL6 conditional knockout mice.Methods:Fifty SPF female TTLL6 brain tissue-specific knockout (TTLL6 CKO: Camk2-Cre + ; TTLL6 f/f) and fifty control (TTLL6 CON: TTLL6 f/f) mice with C57BL/6J background, aged 6 days old were selected.TTLL6 CKO mice were divided into TTLL6 CON control group and TTLL6 CON sevoflurane group, and TTLL6 CKO mice were divided into TTLL6 CKO control group and TTLL6 CKO sevoflurane group, with 25 mice in each group by random block method.Mice in the sevoflurane groups were exposed to 3% sevoflurane with 60% O 2 for 2 hours daily on postnatal days 6, 8, and 10.The mice in control groups received only 60% O 2 under the same condition.The polyGlu-Tubulin and postsynaptic density 95(PSD95) protein expression were detected using Western blot. The expressions of TTLL6, Spastin, and α-Tubulin were assessed via immunofluorescence.Golgi staining and electron microscopy were employed to observe the density of hippocampal dendritic spines and synaptic conditions. The Morris water maze test was used to evaluate spatial memory capabilities. Statistical analysis was performed using GraphPad Prism 8.0 software. Results:(1) Behavioral results showed significant time and group interactions among the four groups in terms of latency to find the platform ( F=8.22, P<0.001).Mice in the TTLL6 CON sevoflurane group had a significantly longer escape latency on days 3-7 compared with the TTLL6 CON control group (all P<0.05), while there was no significant difference between the TTLL6 CKO sevoflurane group and the TTLL6 CKO control group (all P>0.05). The number of platform crossings differed significantly among the four groups ( H=11.95, P=0.007).The TTLL6 CON sevoflurane group had significantly fewer crossing times than the TTLL6 CON control group ( P<0.05), but no significant difference was observed between the TTLL6 CKO sevoflurane group and the TTLL6 CKO control group ( P>0.05). (2) Golgi staining and electron microscopy results revealed significant differences in dendritic spine density and synapse number among the four groups( F=29.00, 41.94, both P<0.001). The dendritic spine density ((5.83±0.40)/10 μm) and the number of synapses ((3.67±0.58)/10 μm) in the TTLL6 CON sevoflurane group were both significantly lower than those in the TTLL6 CON control group ((12.87±1.70)/10 μm, (9.33±0.57)/10 μm)(both P<0.05). In contrast, there was no statistically significant difference between the TTLL6 CKO sevoflurane group and TTLL6 CKO control group (both P>0.05). (3) Immunofluorescence results showed significant differences in the percentage of TTLL6 and Spastin and α-Tubulin co-expressed positive cells in the CA3 region of the hippocampus among the four groups of mice ( F=215.20, 26.08, both P<0.001). The percentage of TTLL6 and Spastin and α-Tubulin co-expressed positive cells in the TTLL6 CON sevoflurane group ((16.75±1.81) %, (47.98±8.42) %) were significantly higher than those in the TTLL6 CON control group ((2.44±0.58) %, (20.07±4.54) %)(both P<0.05), while there was no statistically significant difference between the TTLL6 CKO sevoflurane group and TTLL6 CKO control group ( P>0.05). (4) Western blot results indicated significant differences in the expression of polyGlu-Tubulin and PSD95 proteins in the hippocampal tissue among the four groups of mice ( F=19.66, 8.57, both P<0.001). The TTLL6 CON sevoflurane group had higher polyGlu-Tubulin expression (0.86±0.19) and lower PSD95 expression (0.61±0.13) compared to the TTLL6 CON control group (0.51±0.11, 1.01±0.07) (both P<0.05).However, there was no significant difference between the TTLL6 CKO sevoflurane group and the TTLL6 CKO control group ( P>0.05). Conclusion:The mechanism underlying long-term cognitive impairment in developing brain of neonatal mice caused by repeated sevoflurane anesthesia may relate to the upregulation of TTLL6-induced microtubule polyglutamylation and accelerated Spastin-mediated microtubule severing, which ultimately leads to abnormal dendritic spine development.

Objective:To analyze the clinical characteristics of tigecycline-related adverse reactions and provide the basis for the safe and rational use of the drug.Methods:Adverse reaction reports with suspected drug as tigecycline from Beijing Adverse Drug Reaction Monitoring Center from January 1st, 2019 to June 30th, 2024 were collected. The adverse reaction reports were standardized using the preferred term (PT) and system organ class (SOC) in the Chinese updated edition (2015 version) of the World Health Organization Adverse Reaction Terminology. The patients' general condition, tigecycline use, and adverse reaction occurrence (including latency, severity, treatment, outcome, and correlation evaluation) were descriptively and statistically analyzed. Results:A total of 408 tigecycline-related adverse reaction reports were entered, including 153 females (37.5%) and 255 males (62.5%). The age was (68±21) years, ranging from 2 to 99. The main reasons for tigecycline use were infections of lung, blood flow, skin and skin soft tissue, etc. The pathogens were mainly Klebsiella pneumoniae, Acinetobacter baumanii, Escherichia coli, etc. The usage and dosage of tigecycline in most patients were in line with the instructions. Four hundred and eight adverse event reports involved 11 SOCs and 580 PTs. The top 3 SOCs were gastrointestinal diseases (195 case times, 33.62%), vascular, bleeding and coagulation diseases (183 case times, 31.55%), and hepatobiliary diseases (142 case times, 24.48%). The main clinical manifestations were nausea, vomiting, diarrhea, etc. The main laboratory abnormalities were decreased plasma fibrinogen, decreased platelet count, increased alanine aminotransferase, increased aspartate aminotransferase, and increased bilirubin. There were 27 case times of adverse reactions that were not recorded in the instructions, mainly including leukopenia, abdominal distension, fever, dysbacteriosis, etc. The latency of adverse reactions ranged from 5 min to 65 days, with a median time of 5 days. The grade of adverse reactions was general in 379 patients (92.89%) and severe in 29 patients (7.11%). The top 3 SOCs involved in 53 case times of severe adverse reactions were hepatobiliary diseases (30 case times, 56.60%), vascular, bleeding and coagulation diseases (8 case times, 15.09%), and urinary tract diseases (4 case times, 7.55%), the main clinical manifestations were elevated liver enzymes, coagulation disorders, pancreatitis, etc. After the occurrence of adverse reactions, all patients stopped tigecycline, and received symptomatic treatments such as liver protection, intravenous infusion of human fibrinogen, intravenous infusion of platelets, and antidiarrheal therapy. Among 408 patients, 66 (16.18%) were cured, 297 (72.79%) were improved, 20 (4.90%) were not improved, and 25 cases' outcome (6.13%) were unknown. The shortest time for recovery or improvement was 0.5 hour, the longest was 44 days, with a median time of 5 days. The correlation between tigecycline and adverse reactions was probable in 132 patients (32.35%), and possible in 276 patients (67.65%). Conclusions:Tigecycline-related adverse reactions involve multiple organ systems, mainly including gastrointestinal diseases, vascular, bleeding and coagulation diseases, and hepatobiliary diseases, etc. which can lead to severe adverse reactions such as acute pancreatitis and coagulation disorders. After drug withdrawal and symptomatic treatments, most patients had a good prognosis.

Objectives:Coronary slow flow(CSF)has long been regarded as a marker of coronary microvascular dysfunction(CMD).This study aims to evaluate the diagnostic value of CSF for CMD in patients with angina and nonobstructive coronary arteries(ANOCA).Methods:The study data were derived from the ANOCA-CMD prospective cohort study.All enrolled patients underwent coronary angiography and concurrent coronary physiological assessments in the left anterior descending artery using pressure-wire and thermodilution techniques to obtain coronary flow reserve(CFR)and the index of microcirculatory resistance(IMR).Based on the results,CMD was classified into four subtypes:CMD with elevated IMR(IMR≥25),CMD with reduced CFR(CFR<2.5),CMD with either reduced CFR or elevated IMR(CFR<2.5 or IMR≥25),and CMD with both reduced CFR and elevated IMR(CFR<2.5 and IMR≥25).The corrected thrombolysis in myocardial infarction(TIMI)frame count(CTFC)in the left anterior descending artery was calculated from coronary angiography images,with CSF defined as CTFC>27.This study evaluated the correlation between CTFC,CFR,and IMR,and investigated the diagnostic value of CSF for CMD in ANOCA patients.Results:A total of 103 ANOCA patients were enrolled in this study,with a mean age of(64.2±10.6)years,and 53.4％were female.Among them,57 patients(55.3％)were diagnosed with coronary slow flow.Patients with slow flow had higher IMR(P<0.001)and CFR(P=0.041).Similarly,the proportion of CMD with elevated IMR was higher in the slow flow group(P<0.001),while the proportion of CMD with reduced CFR was lower(P=0.044).There was no significant difference between the groups in the proportions of CMD with either reduced CFR or elevated IMR or CMD with both reduced CFR and elevated IMR(all P>0.05).CTFC was positively correlated with hyperemic mean transit time(r=0.424,P<0.001),IMR(r=0.430,P<0.001),and CFR(r=0.211,P=0.032).The area under the curve(AUC)of CTFC for diagnosing CMD with elevated IMR was 0.721(95％CI:0.623-0.819)with an accuracy of 67％(57％,76％),for diagnosing CMD with reduced CFR was 0.610(95％CI:0.499-0.720)with an accuracy of 60％(50％,70％),for diagnosing CMD with either reduced CFR or elevated IMR was 0.549(95％CI:0.425-0.673)with an accuracy of 47％(37％,57％),and for diagnosing CMD with both reduced CFR and elevated IMR was 0.582(95％CI:0.471-0.693)with an accuracy of 47％(37％,57％).Thus,CSF demonstrated limited diagnostic values across all subtypes of CMD.Conclusions:In ANOCA patients,CSF cannot serve as an effective diagnostic marker for CMD.Therefore,in clinical practice,the slow flow phenomenon should not be directly equated with the presence of coronary microvascular dysfunction in ANOCA patients.

Objectives:To assess the impact of intravascular ultrasound(IVUS)guidance for drug-eluting stent(DES)implantation on the long-term outcomes in coronary artery disease(CAD)patients with chronic kidney disease(CKD).Methods:A retrospective study was conducted on 1 800 CAD and CKD patients who underwent coronary DES implantation at Nanjing First Hospital from January 2018 to December 2022.Patients were divided into IVUS-guided group(IVUS group,n=333)and angiography-guided group(angiography group,n=1 467).Propensity score matching(PSM)was performed at a 1:2 ratio to adjust for differences in baseline clinical and angiographic characteristics between the two groups.Major adverse cardiovascular events(MACE),including cardiac death,target vessel myocardial infarction,and clinically driven target vessel revascularization,were evaluated over a 2-year follow-up.Cox proportional hazards regression was performed to identify independent predictors of MACE.Results:After propensity score matching,333 patients in the IVUS group were matched with 666 patients in the angiography group.Following matching,there were no significant differences in clinical characteristics and angiographic data between the two groups(all P>0.05).Regarding procedural data,IVUS group had a higher number of stents implanted,longer total stent length,larger average stent diameter,more frequent use of post-dilation balloons,larger post-dilation balloon diameter,and greater contrast agent usage(all P<0.05).MACE rate was significantly higher in the angiography group than that in the IVUS group(23.9%vs.18.0%,P=0.037).The difference was mainly attributed to a higher rate of cardiac death in the angiography group(16.1%vs.10.8%,P=0.013).Additionally,patients in angiography group had a significantly higher all-cause mortality rate compared to IVUS group(19.7%vs.13.8%,P=0.022).Multivariate cox regression analysis showed that IVUS guidance(HR=0.73,95%CI:0.55-0.99,P=0.042)was an independent protective factor,while hypertension(HR=1.60,95%CI:1.13-2.26,P=0.008),type 2 diabetes(HR=1.56,95%CI:1.19-2.05,P=0.001),acute coronary syndrome(HR=1.92,95%CI:1.12-3.30,P=0.018),and moderate to severe calcification(HR=1.55,95%CI:1.18-2.04,P=0.002)were independent risk factors for MACE at 2 years after DES implantation in CKD patients.Conclusions:Patients with CAD and CKD,IVUS-guided DES implantation is associated with a reduced risk of MACE and all-cause mortality at 2 years post-procedure compared to coronary angiography-guided implantation.

Tuberculosis remains a significant global public health threat.Early diagnosis and effective treatment are crucial to combat this disease.Yet,traditional diagnostic methods for tuberculosis face limitations due to their low sensitivity,extended detection periods,and dependence on sputum samples.Molecular diagnostic techniques,while offering higher sensitivity,still primarily rely on sputum samples,thereby impeding significant advancements in tuberculosis diagnosis.In clinical settings,there exists a pressing demand for diagnostic approaches that are not solely reliant on sputum samples.In recent years,extracellular vesicles(EVs),as emerging biomarkers,have demonstrated substantial potential in various diseases,including tumors and infectious diseases.A multitude of studies indicate that EVs also exhibit potential in the field of tuberculosis.This review provides an in-depth analysis of the biological characteristics of EVs and their role in the pathogenesis of tuberculosis.It systematically summarizes the progress and significance of EV-based biomarkers in tuberculosis diagnosis,treatment monitoring,and disease mechanism exploration,while addressing the challenges and future prospects in this field.The aim is to offer valuable insights and up-to-date research findings to researchers and clinicians engaged in tuberculosis-related studies.

Objective To explore the application of artificial intelligence quantitative analysis in the prognostic assessment of patients with connective tissue disease-associated interstitial lung disease(CTD-ILD).Methods A total of 67 patients with CTD-ILD were retrospectively selected.All subjects underwent high-resolution computed tomography(HRCT)scanning and were categorized into three groups,namely mild,moderate and severe groups,based on the results of pulmonary function tests.The survival rates of patients in each group were compared using Kaplan-Meier curves and analysis of variance.The univariate analysis was employed to assess the rela-tionships between artificial intelligence parameters and patient prognosis.Significant results were then incorporated into a multifacto-rial Cox regression model to construct the most accurate predictive model.Results A significant difference in survival rate was observed among the three groups(P<0.05).Univariate analysis revealed that the volume and percentage of lung infection in deceased patients were significantly greater than those in surviving patients,while the lung volume in deceased patients was significantly smaller than that in surviving patients.The analysis showed left lung volume and the percentage of lesion components CT value≤-750 HU as risk factors for prognosis,and the combination of these two factors as the most effective predictive model.Conclusion The artificial intelligence analysis system for lung lesions provides a new systematic and quantitative method for the prognostic assessment of CTD-ILD patients,which can be used for the prognostic assessment and follow-up of CTD-ILD patients.
