As a mature neuromodulation technique with sufficient evidence and wide application， transcranial magnetic stimulation （TMS） has become a highly promising approach for the treatment of insomnia disorder. However， there is still a lack of unified standards for formulation of treatment regimens， technical operations， indications and contraindications， treatment of adverse reactions， and application in special populations. In order to standardize the application of TMS in the diagnosis and treatment of insomnia disorder， Professional Committee of Sleep and Neuromodulation of Chinese Sleep Research Society organized the compilation of the technical specifications. This document systematically elaborates on the technical principles and stimulation modes of TMS， summarizes the clinical evidence for its application in the treatment of primary insomnia disorder and comorbid conditions such as depression and cognitive impairment， clarifies the key points for formulating treatment regimens （including stimulation coils， targets， modes， and intensity）， refines the technical specifications such as treatment room setup， personnel qualifications， operation procedures， and efficacy evaluation， and provides recommendations for the management of adverse reactions and principles for use in special populations， which provides a comprehensive expert consensus and practical guidance for the standardized clinical application of TMS in the treatment of insomnia disorder.

AIM: To investigate expression differences and mechanism of action of serine/threonine kinase 1(AKT1), ATP synthase F1 subunit(ATP5F1), and Bcl-2-associated anti-apoptotic gene 3(BAG3)in the occurrence and progression of pterygium.METHODS:Pterygium-related gene expression data were retrieved from GEO database to screen differentially expressed genes(DEGs). String and Cytoscape were used to construct protein-protein interaction(PPI)networks and identify core targets. GO/KEGG enrichment analyzed mitochondrial metabolic pathways. The pterygium samples(head/body)were collected; pathological features were evaluated by HE staining, and the expression of AKT1, ATP5F1, and BAG3 was detected via immunohistochemistry(IHC).RESULTS:A total of 1 264 DEGs were identified(585 upregulated, 679 downregulated). GO analysis showed significant enrichment of mitochondrial pathways regarding to biological processes, cell components and molecular functions; KEGG analysis highlighted oxidative phosphorylation and chemical carcinogenesis-reactive oxygen species(ROS)pathways. The head and body pterygium samples were collected from 28 cases(28 eyes)that received pterygium surgery, including 7 males(7 eyes)and 21 females(21 eyes), with a mean age of 69.32±8.98 years. HE staining showed more severe dysplasia, disordered stroma, and inflammation in the pterygium head versus the body. IHC detection confirmed significantly lower AKT1, ATP5F1, and BAG3 expression in the head compared with the body(all P<0.05).CONCLUSION:GEO-based bioinformatics and experiments confirmed that AKT1/ATP5F1/BAG3(mitochondrial genes)had significant differential expression in pterygium, correlating with pathological progression. They may regulate mitochondrial metabolism to mediate pterygium progression, offering new insights for targeted therapy.

ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis （AS）. MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group， low drug-containing serum group， medium drug-containing serum group， high drug-containing serum group， and positive drug group. After drug intervention， cell proliferation was measured using the cell counting kit-8 （CCK-8） assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase （ALP） activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin （OCN）， osteopontin （OPN）， and runt-related transcription factor 2 （Runx2） was detected by Western blot. The mRNA expression levels of Wnt5a， β-catenin， and Dickkopf-1 （DKK-1） were measured by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression （P<0.05）. The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression （P<0.05， P<0.01）， with the positive drug group showing the most pronounced effect （P<0.01）. The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins （P<0.05， P<0.01）， while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN， OPN， and Runx2 proteins （P<0.05， P<0.01）. ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts， thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression， further inhibiting the transcription of downstream target genes.

OBJECTIVE: To assess the value of chromosomal microarray analysis (CMA) for the detection of low-level mosaicisms in amniotic fluid samples, and to retrospectively analyze the rare cases of mosaicisms. METHODS: Chromosomal karyotype of the fetus was determined by G-banding analysis of cultured amniotic fluid cells. CMA was used to detect copy number variation of fetal chromosomes, and fluorescence in situ hybridization (FISH) was used to determine the proportion of fetal chromosomal mosaicisms in uncultured amniotic fluid cells. RESULTS: Among 825 prenatal samples, 4 cases of true fetal mosaicisms were detected, which yielded an incidence of 0.48%. Two cases were sex chromosomal mosaicisms, and two were autosomal mosaicisms, which involved chromosomes 8 and 9, respectively. All cases were verified by G-banding analysis of cultured amniotic fluid cells, CMA, and/or FISH. CONCLUSION CMA has a great value for detecting low-level mosaicisms in amniotic fluid samples, though the positive results need to be verified by other techniques and should be interpreted with caution. The review of rare cases can provide a basis for prenatal genetic counseling.

Objective To explore the traditional Chinese medicine(TCM)syndrome characteristics of patients with Chikungunya hemorrhagic fever and to provide empirical data to support the application of TCM in diagnosing and treating Chikungunya hemorrhagic fever.Methods A cross-sectional survey was conducted to collect clinical data(sex,age,days since onset,and comorbidity underlying disease conditions)and TCM with four-examination information(symptoms,tongue manifestations,and pulse manifestations)from 255 patients with Chikungunya hemorrhagic fever who visited Lecong Hospital of Shunde,Foshan,the Third People's Hospital of Shunde District of Foshan,Shunde Hospital of Southern Medical University Affiliated Chencun Hospital between July 23 and July 29,2025.Factor and cluster analyses were used to summarize TCM syndrome characteristics and analyze core pathogenesis in conjunction with clinical features.Results Among the 255 patients with Chikungunya hemorrhagic fever,131 were male and 124 were female,with a age of(49.05±17.93)years and a disease duration of(3.26±1.78)days.Among the four types of examination information in TCM,35 items exhibited a frequency exceeding 10%.The most prevalent symptoms were arthralgia(180 patients,70.59%),exanthem(153 patients,60.00%),fatigue(99 patients,38.82%),anhidrosis(98 patients,38.43%),pruritus(96 patients,37.65%),and fever(92 patients,36.08%).Tongue and pulse manifestations were primarily white fur(155 patients,60.78%),pink tongue(111 patients,43.53%),slippery pulse(143 patients,56.08%),and greasy fur(134 patients,52.53%).Patients with disease onset≤3 d had a higher incidence of arthralgia,fatigue,fever,aversion to cold,generalized muscle pain,aversion to wind,insomnia,headache,sweating,low-grade fever,poor appetite,loose stool,hyperhidrosis,and red tongue than those with disease onset≥4 d(P<0.05).Patients with disease onset≥4 d had a higher incidence of pink tongue and thick fur than those with disease onset≤3 d(P<0.05).The syndrome elements in patients with Chikungunya hemorrhagic fever predominantly manifested on the defensive exterior,with involvement of the sinew-bone joints,skin-muscle,and spleen.Pathogenic factors were primarily characterized by external winds,dampness,and heat.Factor and cluster analysis result indicated three TCM pathogenesis progression patterns:imbalance of the defensive exterior with wind-dampness conflict and heat transformation;dampness-heat flowing into muscles and meridians causing joint obstruction and qi blood stasis;and dampness-heat congelation resulting in qi mechanism obstruction,consumption of body fluids,and infiltration of the skin.Conclusion Patients with Chikungunya hemorrhagic fever primarily present with fever,joint pain,and rashes.In TCM,this condition falls under the category of"dampness-warmth"syndrome.Its etiology is attributed to pathogens,with transmission occurring through mosquito bites.The core pathogenesis of TCM is the invasion of the defensive exterior and dampness-toxic heat accumulation.The therapeutic principles focus on clearing heat pathogens,resolving dampness pathogens,dispersing wind pathogens,and promoting the resolution of rashes.

Objective To investigate whether the application of automated software for computed tomography angiography(CTA)and computed tomography perfusion imaging(CTP)can improve in-hospital workflow for endovascular treatment(EVT)in acute ischemic stroke patients.Methods We included patients with acute ischemic stroke who received CTA and CTP evaluation followed by EVT through the stroke emergency pathway at the Affiliated Hospital of Southwest Medical University between January 1,2020 and December 30,2022.The patients were divided into two groups:control group and artificial intelligence(Al)group based on whether automated software was used for assessment.The control group consisted of patients who underwent manual post-processing of multimodal imaging before June 2021,while the AI group was composed of patients whose imaging was processed with automated software from July 2021 onwards.The primary outcome was door-to-puncture time(DPT),and the secondary outcome was the 90-day modified Rankin Scale(mRS)score.Results A total of 312 patients were included,with 145 in the control group and 167 in the AI group.The median age of all the patients was 68 years(range:58-74 years),and 55.4％(173 patients)were male.The median National Institutes of Health Stroke Scale(NIHSS)score at presentation was 16 scores(range:12-19 scores).The median DPT was reduced from 110 min(range:80-150 min)before the use of automated software to 95 min(range:65-125 min)after its implementation(P＜0.001).However,there was no significant difference in the proportion of patients achieving functional independence(mRS score of 0-2)between the two groups(39.3％vs.41.3％,P=0.719).Conclusion The application of multimodal CT automated software improves the in-hospital workflow for acute ischemic stroke patients by reducing the time to EVT.However,the software did not significantly impact neurological functional outcomes as measured by the mRS.

Objective:To investigate the distribution and clinical significance of amniotic fluid karyotype results in 2 725 cases from southern Anhui.Methods:The karyotypes of amniotic fluid from 2 725 cases of second-trimester pregnant women treated in our hospital from Jan 2017 to Dec 2023 were collected.The annual abnormal detection rate and overall abnormal rate were analyzed.Meanwhile,the abnormal detection rate was compared among 8 groups of different clinical indication including adverse pregnancy history,advanced maternal age(≥35 years),high risk of Down syndrome screening,high risk of non-invasive prenatal testing(NIPT),nuchal translucency thickness(NT)≥2.5 mm,abnormal ultrasound findings,two or more concurrent positive indications,and others.The abnormal detection rate was calculated within high risk of Down syndrome screening and NIPT.Results:Significant differences in annual abnormal rates were observed from 2017 to 2023(χ2=19.705,P=0.003).Among 2 725 cases,233(8.55%)showed abnormal karyotypes.Among them,abnormal autosomal number was the most prevalent(4.41%,120/2 725),with inversion being the most common chromosome structural abnormality.Significant differences in abnormal rates were noted among the eight clinical indication groups(χ2=438.516,P＜0.01).No statistical difference was found in abnormal detection rates among the three high-risk subgroups of Down syndrome screening(χ2=0.323,P=0.851),while significant differences were observed within the high-risk subgroups of NIPT(χ2=100.901,P＜0.01).Polymorphisms were detected in 65 cases(2.38%).Conclusions:Chromosomal numerical and structural abnormalities have been detected in southern Anhui over the past seven years,with variations across subgroups.Karyotype analysis effectively detects second-trimester fetal chromosomal abnormalities,aiding in the prevention of birth defects and worthing clinical application.

Gastric cancer is a malignant tumor of the digestive system with strong invasiveness and a high metastasis rate.Its morbidity and mortality rank among the top five in the world and the prognosis is closely related to the disease stage.Multidisciplinary comprehensive treatment based on systemic antitumor drugs is generally adopted in patients with advanced or metastatic gastric can-cer,but the prognosis is typically poor.With the in-depth research on the tumor microenvironment,the development of multi-omics technology,and the application of immunotherapy and neoadjuvant chemoradiotherapy,the therapeutic effect of advanced gastric can-cer has been initially improved,and immunotherapy has become the most potential of the treatment strategies.Many studies have found that Helicobacter pylori(Hp)infection status is closely related to the efficacy of immunotherapy for gastric cancer,especially im-mune checkpoint inhibitors(ICIs),but there is not clear whether it has advantages or disadvantages.This article reviews the current research on the efficacy of Hp on ICIs in advanced gastric cancer to provide ideas for further research on the interaction between Hp in-fection and tumor immunotherapy.

Objective To investigate the protective effects and possible mechanisms of sofalcone on small intestinal mucosal damage induced by nonsteroidal anti-inflammatory drugs(NSAIDs)in rats.Methods In the first group of animal experiments,rats were randomly divided into five groups:normal control group,diclofenac group(diclofenac 7.5 mg·kg-1),and sofalcone high-doses groups(sofalcone 10 mg·kg-1+diclofenac 7.5 mg·kg-1),sofalcone medium-doses groups(sofalcone 5 mg·kg-1+diclofenac 7.5 mg·kg-1),and sofalcone low-doses groups(sofalcone 2 mg·kg-1+diclofenac 7.5 mg·kg-1).Each group received daily gavage for seven days.Serum D-lactate levels were measured,and histological damage to the small intestine was assessed through HE staining and pathological scoring.In the second group,rats were separated into three groups:normal control group,diclofenac group(diclofenac 7.5 mg·kg-1),and sofalcone group(sofalcone 2 mg·kg-1+diclofenac 7.5 mg·kg-1).Concurrently,the rats'body mass,24-hour diet,and water intake were monitored.Additionally,serum levels of pro-inflammatory cytokines such as IL-6,IFN-γ,TNF-α,inflammatory markers CRP and D-lactate,as well as measurements of tissue reactive oxygen species(ROS),lactate dehydrogenase(LDH),and mitochondrial membrane potential were conducted using appropriate kits.Western blotting was applied to assess the expression levels of intercellular junction proteins(Occludin,Claudin-1,α-Catenin),programmed necrosis pathway-associated proteins including receptor-interacting protein kinase 1(RIPK1),RIPK3,and mixed lineage kinase domain-like pseudokinase(MLKL)along with p-MLKL.Results In the first experiment,the diclofenac group exhibited significant histological damage to the small intestine,with elevated levels of D-lactic acid and pathological scores compared to the normal control group(P<0.01).Following intervention with sofalcone,both the histological damage and the levels of D-lactic acid and pathological scores in the small intestine were notably reduced(P<0.05 or P<0.01).However,there was no substantial difference in pathological scores among different doses of sofaclone groups(P>0.05).In the second experiment,compared with normal control group,rats in the diclofenac group showed decreased body mass,24-hour average diet and water intake,along with elevated levels of IL-6,IFN-γ,TNF-α,CRP,D-lactic acid,tissue ROS,LDH activity,RIPK1,RIPK3,and p-MLKL/MLKL protein expression levels,as well as mitochondrial membrane potential(P<0.05 or P<0.01).Moreover,Occludin,Claudin-1,and α-Catenin protein expression levels were reduced(P<0.05 or P<0.01).Following sofalcone intervention,the previously mentioned parameters were reversed(P<0.05 or P<0.01).Notably,there was no statistically significant difference observed in the reduction of RIPK1 protein expression(P>0.05).Conclusions Sofalcone reduces NSAID-induced small intestinal mucosal injury in rats by inhibiting the RIPK1/RIPK3/MLKL-dependent programmed necrosis pathway.
