Based on commonly used acupoints in the clinical acupuncture treatment of functional dyspepsia （FD）， this study systematically analyzes the therapeutic differences and synergistic effects between local and distal point selection. It also examines the suitability of primary acupoint selection for different FD subtypes， postprandial distress syndrome （PDS） and epigastric pain syndrome （EPS）. The findings suggest that a combination of local and distal acupoints may be more appropriate as primary points for PDS， whereas local acupoints alone may be more suitable for EPS. Additionally， the study explores the impact of various factors， such as stimulation techniques， needling order， intensity or stimulation parameters， and depth， on the efficacy of acupuncture. It concludes that the intrinsic properties of acupoints are the primary determinants of therapeutic direction. Other factors mainly influence the magnitude rather than the direction of the effect. Future research may further investigate how different acupoint combinations， local versus distal， affect the treatment outcomes of FD subtypes， providing new insights for clinical acupuncture prescriptions.

AIM:This study aims to investigate the impact of chronic kidney disease(CKD)on the growth,development,and cognitive function of offspring rats,and to evaluate the effects of esaxerenone(ESAX)intervention.METHODS:Thirty female non-pregnant Wistar rats were randomly assigned to three groups:sham operation+pregnancy(control group),UUO+pregnancy(model group),and UUO+pregnancy+esaxerenone(treatment group),with 10 rats in each group.CKD was induced in the UUO+pregnancy and UUO+pregnancy+esaxerenone groups by performing uni-lateral ureteral obstruction(UUO),while the sham operation+pregnancy group underwent a non-ligated and non-clipped ureter procedure.Rats in the treatment group received esaxerenone at a dosage of 1 mg·kg-1·d-1.Vaginal smears were per-formed weekly from the 8th week post-UUO to monitor the estrous cycle.Female and male rats in pre-estrus or estrus were paired in a 2∶1 ratio,and the day with the first appearance of sperm in vaginal smears was recorded as the first day of preg-nancy.Offspring were delivered 21 to 22 days post-gestation,and 10 offspring from each group were selected for further experimentation:sham-offspring(sham-offspr)group,UUO-offspro group,and esaxerenone treatment offspring(ESAX-offspr)group.At 21 days of age,offspring weight and tail length were measured.Behavioral tests,including the open field test,Y maze test,and Morris water maze test,assessed learning and memory abilities.Serum levels of aldosterone,5-hydroxytryptamine(5-HT),and brain-derived neurotrophic factor(BDNF)were measured using ELISA.Serum creati-nine(SCr)and blood urea nitrogen(BUN)levels were assessed using conventional biochemical methods.Renal pathology was examined using Hematoxylin-Eosin(HE)staining.RESULTS:Offspring in the UUO-offspr group had reduced body weight and tail length compared to the sham-offspr group(P＜0.05).Behavioral tests indicated that exploration and memo-ry abilities were significantly impaired in the UUO-offspr group compared to the sham-offspr group(P＜0.05),while the ESAX-offspr group showed improved behavioral development compared to the UUO-offspr group(P＜0.05).ELISA results revealed decreased levels of serum 5-HT,BDNF,and aldosterone in the UUO-offspr group compared to the sham-offspr group(P＜0.01),with increased levels in the ESAX-offspr group(P＜0.05).Renal function tests showed elevated SCr and BUN levels in the UUO-offspr group compared to the sham-offspr group(P＜0.01),while levels in the ESAX-offspr group were reduced(P＜0.01).HE staining demonstrated mild tubular dilation and inflammatory cell infiltration in the UUO-offspr group,whereas the ESAX-offspr group had well-arranged tubules with reduced inflammation.CONCLU-SION:Chronic kidney disease adversely affects the growth,development,and cognitive function of offspring rats by 21 days of age.Esaxerenone intervention can mitigate these detrimental effects on growth,development,and cognitive abili-ties in offspring rats.

Aim To study the mechanism of salidro-side combined with rosavin in rats with ischemic stroke.Methods The MCAO rats was established by using thread-embolic method.The rats were divided into the sham group,MCAO group,salidroside com-bined with rosavin group,and positive control group;the drug was given continuously for seven days.Western blot was used to detect apoptosis indicators.Proteomics was used to analyse differential proteins(DEPs).STEP receptor inhibitor was injected into the lateral ventricles,the rats were administered for seven days,then the apoptosis indicators were detected.Re-sults Salidroside combined with rosavin could reduce neurological function scores in MCAO rats and inhibit cell apoptosis.Quantitative proteomics identified 496 DEPs in brain tissue and discovered core proteins STEP,p38,and CRTC1.Salidroside combined with rosavin could promote the STEP and CRTC1 while in-hibiting p38 protein.After treatment with STEP inhibi-tor,those effects were reversed.Conclusion Salidro-side combined with rosavin can inhibit cell apoptosis in MCAO rats,which is closely related to the regulation of the STEP/p38/CRTC1 signaling pathway.

Aim To investigate the antidepressant mechanism of hyperforin via the utilization of single-cell sequencing technology.Methods C57BL/6 mice were randomly divided into the control group,depres-sion model group,and hyperforin intervention group.The chronic unpredictable mild stress(CUMS)model was induced and drug interventions were administered for 28 d.Behavioral experiments were conducted to as-sess depressive symptoms,and hippocampal tissue was collected for single-cell RNA sequencing.Key cell populations and differentially expressed genes across groups were identified,followed by PPI network,GO,and KEGG enrichment analysis.Results Behavioral experiments indicated that CUMS successfully induced depressive symptoms in mice,while hyperforin im-proved depressive behavior.In the depression model group,the proportion of brain perivascular macrophages(PVM)increased,and this proportion decreased after hyperforin intervention,approaching the level seen in the control group.The top 20 common differentially ex-pressed genes in the PVM subpopulation were Saa3,Hbb-bs and Ccl24.PPI network analysis identified core targets,including Ccl2,Dhx9,C3,Msr1,Cxcl2 and Cx3cr1.KEGG enrichment analysis revealed pathways related to chemokines,phagosome formation,and inosi-tol phosphate metabolism.Conclusion The antide-pressant mechanism of hyperforin may be related to the regulation of Ccl24 and its related chemokine signaling pathway by PVM.

Objective To estimate the prevalence of calcified nodule(CN)among patients with coronary artery disease(CAD)and identify the possible risk factors associated with an increased CN risk.Methods Databases include PubMed,Web of Science and Embase was conducted to identify studies reporting the prevalence and/or risk factors of CN.For this databases,the search was from inception to January 1,2024.Data analyses was performed using R statistical Software 4.2.2.Results A total of 46 studies involving 17 926 patients were included.Among them,13 studies with 4 187 patients reported both the prevalence and associated risk factors.The overall prevalence of CN was found to be 5.72％(95％CI 4.47％-7.31％),while in studies reporting both the prevalence and risk factors,the CN prevalence was slightly higher at 8.72％(95％CI 6.43％-11.71％).Hypertension(OR 1.75,95％CI 1.29-2.37),diabetes(OR 1.84,95％CI 1.46-2.33),chronic kidney disease(OR 2.50,95％CI 1.67-3.74),and hemodialysis(OR 7.77,95％CI 4.77-12.67)were associated with an elevated CN risk(all P＜0.001).Conversely,obesity(OR 0.39,95％CI 0.18-0.83)and history of smoking(OR 0.61,95％CI 0.47-0.80)were linked to a decreased CN risk(both P＜0.05).Conclusions The overall prevalence of CN is relatively low among patients with CAD.However,the prevalence of CN is influenced by a variety of clinical factors.Further research is warranted to elucidate the underlying mechanisms.

Aim To investigate the therapeutic effects of a newly developed Tadalafil tablets on pathological myocardial hypertrophy induced by abdominal aortic constriction(AAC)in rats,as well as its influence on the activation of the NF-κB signaling pathway in myo-cardial cells.Methods SD rats were randomly divid-ed into 4 groups:the sham operation group(Sham),the model group(AAC),the tadalafil new tablet treat-ment group(N-Tad,5 mg·kg-1),and the positive control drug treatment group(Cialis,10 mg·kg-1g).The AAC model group and treatment group rats under-went blunt dissection and constrictive ligation of the abdominal aorta at the left renal artery branch point during surgery,while the Sham group rats only had their arteries separated without any constrictive liga-tion.Rats in the treatment groups received either N-Tad or Cialis via gavage three days after modeling,while rats in the sham group and the model group re-ceived physiological saline daily for 8 weeks.Small an-imal ultra-high-resolution echocardiography and hemo-dynamic assessment were applied to evaluate left ven-tricular function in each group of rats,and the calcula-tion of the left ventricular mass index was conducted.By employing Western blot and RT-PCR.we assessed the impact of this treatment on the expression of the hy-pertrophy factor atrial natriuretic peptide(ANP),phosphorylated NF-κB p65 protein(p-NF-κB p65),and phosphorylated IκB-α in the left heart tissue of rats and in H9c2 cardiomyocytes.Results Compared to the Sham group,the AAC rats exhibited a significant decrease in left heart function,an increase in left ven-tricular mass index,and a notable increase in ANP and p-p65 expression in the left heart tissue(P＜0.05).Both N-Tad and Cialis treatments could significantly enhance left ventricular function,decrease left ventric-ular mass index,and inhibit the expression of ANP and phosphorylated NF-κB p65 in rats with myocardial hy-pertrophy(P＜0.05).Notably,the therapeutic effect of low-dose N-Tad was comparable to that of high-dose Cialis.At the cellular level,Tadalafil significantly in-hibited the activation of the NF-κB signaling pathway and reduced the expression of associated proteins in H9c2 cardiomyocytes.Conclusions N-Tad can sig-nificantly inhibit p65 and IκB-α phosphorylation,and the activation of the NF-κB signaling pathway,reduce ANP expression,and improve pathological myocardial hypertrophy,as well as mitigate left heart function damage caused by abdominal aortic constriction.

Objective:To investigate intraoperative pathological findings and the interventional effects of "deep cervical lymphaticovenous anastomosis+" (dcLVA+) on deep cervical lymphatic drainage as well as the blood flow of carotid artery and jugular vein in elderly patients with cognitive impairment, and to put forward the thoughts based on the findings from the surgery.Methods:Between May 2024 and December 2024, retrospective analysis of Microsurgery Hospital, Fengcheng Hospital, Xi'an Medical College performed dcLVA+ between the deep cervical lymphatics or lymph nodes and jugular veins in 50 elderly patients with cognitive impairment (19 males and 31 females, aged 55-88 years with 69.94 years in average). Nine patients were found with Clinical Dementia Rating (CDR) score at 1 (mild), 7 with CDR score at 2 (moderate) and 34 with CDR score at 3 (severe). Intraoperative observations based on literature reviews had identified anatomical relationships between the lymphatic sacs containing cervical lymphatic chain and the carotid sheath. The lymph node count, size, distribution, thickness of fat tissue and conditions of lymphatic vessels were documented. Ultrasound was used to compare the blood flow of carotid artery and jugular vein as well as the cross-sectional areas at the planes of hyoid and cricoid cartilage before and after the closure of incisions under anaesthesia in 39 patients. Correlation analyses for Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCa), Activities of Daily Living (ADL) and Agitation behavior score before and 1 week after surgery were performed using Spearman's correlation and Wilcoxon paired tests. P<0.05 was considered statistically significant. Postoperative follow-ups were conducted via the visit of outpatient clinic and WeChat and telephone interviews. Results:In surgery, the cervical lymphatic chain was found running within an almost enclosed sac surrounding the carotid sheath. There were enlarged lymph nodes, increased fat deposition, lymphatic dilation or fibrosis in the sac. The preoperative blood flow in the carotid artery at the planes of hyoid and cricoid cartilage in the 39 patients was recorded at 150.52 ml/min±40.33 ml/min and 358.29 ml/min±129.30 ml/min, while that in the jugular vein was at 172.50 ml/min±63.94 ml/min and 317.00 ml/min±105.21 ml/min, respectively, both were far lower than the normal blood flow. There were statistically significant differences in the blood flow of carotid artery and jugular vein before and after surgery ( P<0.01). It was found that the preoperative blood flow of the internal carotid artery at the plane of hyoid was positively correlated with the preoperative scores of MMSE ( P<0.01), MoCa ( P<0.05) and ADL ( P<0.01). The blood flow of the common carotid artery at the plane of cricoid cartilage was found significantly and positively correlated with the preoperative scores of MMSE ( P<0.05). It was also noted that the blood flow of the internal carotid artery at the plane of hyoid was significantly and positively correlated with the postoperative ADL ( P<0.01) but negatively correlated with the Agitation behavior score ( P<0.05). The blood flow of the common carotid artery at the plane of cricoid cartilage was significantly and positively correlated with the postoperative scores of MMSE and MoCa ( P<0.05). The blood flow of the internal jugular vein at the plane of hyoid was negatively correlated with the Agitation behavior score ( P<0.01). The cross-sectional area of carotid artery at the plane of left hyoid was significantly and positively correlated with the MMSE score ( P<0.05). Statistically significant differences were observed in MMSE, MoCa, ADL and Agitation behavior score before and after surgery ( P<0.01). Conclusion:dcLVA+ shows a certain therapeutic benefit to the elderly patients with cognitive impairment. The intraoperatively observed pathological changes in cervical lymphatic sacs affect deep cervical lymphatic drainage and the blood flow of carotid artery and jugular vein. Further studies are necessary to find out whether the findings from this study would be the specific pathological changes and the morbidity mechanisms among the elderly patients with cognitive impairment.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.

Objective To characterize the changing species distribution and antibiotic resistance profiles of respiratory isolates in hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Methods Commercial automated antimicrobial susceptibility testing systems and disk diffusion method were used to test the susceptibility of respiratory bacterial isolates to antimicrobial agents following the standardized technical protocol established by the CHINET program.Results A total of 589 746 respiratory isolates were collected from 2015 to 2021.Overall,82.6％of the isolates were Gram-negative bacteria and 17.4％were Gram-positive bacteria.The bacterial isolates from outpatients and inpatients accounted for(6.0±0.9)％and(94.0±0.1)％,respectively.The top microorganisms were Klebsiella spp.,Acinetobacter spp.,Pseudomonas aeruginosa,Staphylococcus aureus,Haemophilus spp.,Stenotrophomonas maltophilia,Escherichia coli,and Streptococcus pneumoniae.Each microorganism was isolated from significantly more males than from females(P＜0.05).The overall prevalence of methicillin-resistant S.aureus(MRSA)was 39.9％.The prevalence of penicillin-resistant S.pneumoniae was 1.4％.The prevalence of extended-spectrum β-lactamase(ESBL)-producing E.coli and K.pneumoniae was 67.8％and 41.3％,respectively.The overall prevalence of carbapenem-resistant E.coli,K.pneumoniae,Enterobacter cloacae,Pseudomonas aeruginosa,and Acinetobacter baumannii was 3.7％,20.8％,9.4％,29.8％,and 73.3％,respectively.The prevalence of β-lactamase was 96.1％in Moraxella catarrhalis and 60.0％in Haemophilus influenzae.The H.influenzae isolates from children(＜18 years)showed significantly higher resistance rates to β-lactam antibiotics than the isolates from adults(P＜0.05).Conclusions Gram-negative bacteria are still predominant in respiratory isolates associated with serious antibiotic resistance.Antimicrobial resistance surveillance should be strengthened in clinical practice to support accurate etiological diagnosis and appropriate antimicrobial therapy based on antimicrobial susceptibility testing results.

AIM:To investigate the possible mechanism how orphan nuclear receptor 4A1(NR4A1)affects renal fibrosis in unilateral ureteral obstruction(UUO)mice.METHODS:(1)Specific pathogen-free(SPF)male C57BL/6J mice(5 to 6 weeks old)were randomly divided into sh-Con+sham group(n=6),sham+sh-NR4A1 group(n=6),sh-NR4A1+UUO group(n=6),and sh-NR4A1+UUO group(n=6).Renal NR4A1 knockdown mice were prepared by intrarenal injection of NR4A1 viral vector.(2)SPF male C57BL/6J mice(5 to 6 weeks old)were randomly assigned to in sham group,UUO group,and UUO+cytosporone-B(Csn-B)group.An animal model of renal fibrosis was prepared by UUO,and Csn-B was intervened for 14 days.HE,Masson,and Sirius red staining were used to observe renal pathological damage.Immunohistochemistry and Western blot were performed to detect the expression of NR4A1,interferon-γ(IFN-γ),α-smooth muscle actin(α-SMA)and vimentin.The purpose of this study is to observe the regulatory effect of NR4A1 on UUO-induced renal fibrosis.RESULTS:(1)The expression of NR4A1 was decreased in kidney tissues of UUO mice(P<0.05).(2)HE staining results showed that there are tubular dilation,atrophy,and massive inflammatory cell infiltra-tion in sh-Con+UUO group,and NR4A1 knockdown can aggravate UUO-induced kidney damage(P<0.05).The results of Masson and Sirius red staining showed a banded distribution of collagen deposition in the sh-Con+UUO group,and colla-gen deposition increased significantly after NR4A1 knockdown(P<0.05).Treatment with Csn-B could improve renal path-ological damage and reduce collagen deposition.(3)UUO could upregulate the expression of α-SMA and vimentin,and NR4A1 knockdown could significantly increase UUO-induced their expression(P<0.05).In addition,Csn-B could im-prove UUO-induced renal fibrosis(P<0.05).(4)The expression of IFN-γ was increased in UUO mice,and NR4A1 knockdown could upregulate UUO-induced IFN-γ expression(P<0.05).Moreover,Csn-B could down-regulate UUO-in-duced IFN-γ expression(P<0.05).CONCLUSION:NR4A1 can affect renal fibrosis by regulating IFN-γ in UUO mice.
