Objective: Patients with atherosclerotic cardiovascular disease (ASCVD) following percutaneous coronary intervention (PCI) are classified as very-high-risk individuals in cardiovascular disease (CVD) risk stratification. The distribution pattern of traditional Chinese medicine (TCM) syndromes in this patient population, as well as its association with blood lipid profiles and clinical prognosis, remains unclear. The present prospective cohort study aims to investigate these correlations, thereby providing insights to enrich the research fields. Methods: We enrolled consecutive patients with ASCVD who underwent PCI at the Integrated Cardiology Unit of China-Japan Friendship Hospital between September 1, 2020 and December 31, 2022. Demographics and clinical characteristics, signs and symptoms defining each TCM syndrome, and fasting venous blood samples were collected at baseline and follow up or upon major adverse cardiovascular events (MACEs). We analyzed the correlation between TCM syndromes, blood lipid profiles, and MACEs, and developed a new joint prognostic model incorporating both TCM syndromes and blood lipids using logistic regression. The analyses were based on detailed baseline and one-year follow-up data. Results: A per-protocol analysis was performed on 586 patients with complete data ultimately. During the one-year follow-up, 174 patients (29.69%) experienced a MACE. We performed statistical analyses on comorbidities, medication, and biochemical indicators across groups defined by TCM syndrome differentiation. When comparing different TCM syndromes, no significant differences were found in age, body mass index (BMI), history of revascularization, comorbidities, family history of CVD, smoking or drinking, or statin intensity (P > 0.05). Patients with intertwined phlegm and blood stasis syndrome exhibited significantly higher levels of total cholesterol (TC, 5.27 ± 1.18 mmol/L, P < 0.001), triglyceride (TG, 1.96 ± 1.33 mmol/L, P = 0.008), low-density lipoprotein cholesterol (LDL-C, 3.35 ± 0.79 mmol/L, P < 0.001), and high-density lipoprotein cholesterol (HDL-C, 1.24 ± 0.81 mmol/L, P < 0.001) compared with those with other TCM syndromes combined. A multivariable logistic regression model was constructed to predict MACEs. The model included TCM syndrome type [with intertwined phlegm and blood stasis as a predictor, adjusted odds ratio (OR) = 1.413, 95% confidence interval (CI): 0.517 – 3.864, P = 0.501], age (adjusted OR = 0.97, 95% CI: 0.955 – 1.001, P = 0.057), male gender (adjusted OR = 0.698, 95% CI: 0.416 – 1.170, P = 0.173), TC (adjusted OR = 1.004, 95% CI: 0.513 – 1.965, P = 0.990), and LDL-C (adjusted OR = 5.825, 95% CI: 2.214 – 15.326, P < 0.001). This model demonstrated good discriminatory ability for MACEs in post-PCI ASCVD patients [the area under the receiver operating characteristic (ROC) curve (AUC) = 0.865, 95% CI: 0.816 – 0.914]. Conclusion The intertwined phlegm and blood stasis TCM syndrome is associated with a distinct atherogenic lipid profile characterized by elevated levels of TC and LDL-C. The prognostic model that incorporates this TCM syndrome type along with conventional lipid parameters (TC and LDL-C) shows good discriminatory ability for predicting MACEs in ASCVD patients after PCI, underscoring the potential clinical utility of integrating TCM syndrome differentiation into CVD risk assessment.

This study explores methodological issues in the design， evaluation， and reporting of randomized controlled trials （RCTs） under the concept of "syndrome dominating disease". The discussion focuses on key aspects including the adaptability of trial design， the screening of research participants， the standardization of syndrome differentiation， the balance between intervention individualization and standardization， the integration of multi-dimensional outcome measures， and the limitations of existing evaluation and reporting tools when applied to this type of research， along with corresponding recommendations and future perspectives. Regarding research design， it is recommended to select or draw upon innovative design concepts such as basket trials and subgroup-based dynamic/static parallel-group designs， in order to innovate the design format of RCTs. Meanwhile， criteria for participant screening， TCM syndrome differentiation， and disease classification should be standardized. The balance should be appropriately achieved between intervention individualization and standardization， and a multidimensional assessment system encompassing TCM syndromes， disease-specific outcomes， and patient-reported outcomes should be established. For risk of bias assessment and research reporting， it is recommended，to develop specialized assessment and reporting tools based on existing instruments， in order to standardize the assessment and reporting of study findings. Future research may further explore the potential applications of artificial intelligence in the study design， risk-of-bias assessment， and reporting quality assessment of RCTs based on the "syndrome dominating disease" model， with a particular focus on methodological optimization， data integration， and enhancement of research quality.

Objective: To investigate the environmental contamination of norovirus in nurseries and primary/secondary schools, so as to provide a scientific basis for effective prevention and control measures. Methods: A total of 483 external environmental samples were collected from 34 cluster outbreaks of norovirus gastroenteritis in kindergartens and primary/secondary schools in Linhai City from 2021 to 2024. Pathogen detection was conducted using a rapid nucleic acid extraction kit and realtime fluorescence RT-PCR, and the results were analyzed using the χ2 test or Fishers exact test. Results: Among the collected external environmental samples, the total positive rate of surface contamination was 13.66%. The positive rates in kindergartens and primary/secondary schools were 12.20% and 15.82%, respectively. In kindergartens, the five surfaces with the highest detection rates were desks/chairs (23.33%), toilet stool troughs (20.69%), urinal troughs (12.00%), washbasins/sinks (11.11%), and toilet mops (9.38%). In primary/secondary schools, the top five were toilet stool troughs (38.30%), urinal troughs (23.53%), toilet door handles (13.04%), toilet mops (12.50%), and drinking cups (11.11%). The difference in positive detection rates among different external environments in primary/secondary schools was statistically significant (Fishers exact probability test, P<0.01). The positive detection rate in sanitary toilets was higher than that in classroom environments (χ2=17.38), while the positive detection rate in classroom environments of kindergartens was higher than that in primary/secondary schools (χ2=5.42)(P<0.05). Conclusions Norovirus exhibits a high contamination rate in nurseries and schools, particularly in restroom areas. Strengthening sanitation and disinfection in highrisk environments, and improving hygiene awareness among children and staff, are essential for the effective prevent and control of norovirus.

Objective:To investigate the molecular mechanisms of bexarotene in treating double hit lymphoma(DHL)based on Weighted Gene Co-expression Network Analysis(WGCNA),thereby providing potential targets and experimental evidence for DHL treatment.Methods:The gene expression datasets GSE44164 and GSE43677 were downloaded from the Gene Expression Omnibus(GEO)database,and differentially expressed genes(DEGs)were identified.WGCNA was employed to identify gene modules associated with DHL.A protein-protein interaction(PPI)network was constructed to screen for key hub genes.Drug-gene association analysis was conducted using the EpiMed platform to identify potential targeted drugs for DHL.The effects of bexarotene on DHL cell proliferation and key protein expression were evaluated using the CCK-8 assay and Western blotting(WB),and its effects on cell apoptosis was evaluated using flow cytometry.Results:WGCNA identified a turquoise module highly associated with DHL,and 10 hub genes(COL1A2,COL3A1,MMP2,COL5A2,DCN,BGN,FN1,MMP9,FBN1,and LUM)were screened from the PPI network.Drug association analysis nominated bexarotene as a potential therapeutic agent.In vitro validation demonstrated that bexarotene significantly inhibited U2932 cell viability(P<0.05),promoted cell apoptosis(P<0.001),and downregulated c-Myc and COL1A2 expression(P<0.05).Conclusion:Bexarotene may exert anti-DHL effects by suppressing the c-Myc signaling pathway and modulating extracellular matrix-related genes.Further studies are warranted to validate its in vivo efficacy and potential for combination therapy.

In order to investigate the related pathogens and reveal the etiological characteristics of gout in goslings,191 typical clinical cases from partial regions of China were examined by RT-PCR/PCR detection of viral nucleic acids in domestic poultry and pathological analysis.The autop-sy results show that the clinical cases could be classified into three types based on the severity of urate deposition:severe,moderate,and mild,namely systemic urate deposition,local urate deposi-tion mainly in the liver and kidneys,and only a small amount of fine-grained urate deposition in the liver,gallbladder,or glandular stomach.The results of RT-PCR/PCR detection showed that the to-tal positive rates were as follows:GAstV Group2 63.9％,GAstV Group1 50.3％,AAstV-2 38.7％,novel Muscovy duck parvovirus(NPV)17.8％,GPV 16.2％,GoCV 12.6％,MDPV 7.9％,MDRV 8.4％,DPV 0.5％,GPMV and NDV 0.5％,the AstV-1、ARV、TMUV、NDV、FAdV、GHPyV were zero.Among all the postive samples,the rates of single positive,double positive,and multiple posi-tive were 18.3％,27.2％,and 44.0％,respectively.The rate of single positive samples containing AAstV was only 12.0％,the double or multiple positive samples containing GAstV Group 1/2 was 60.7％,and the rate of samples without GAstV Group 1/2 was 10.5％.The results also showed that 20(10.5％)samples were negative for 16 types of viruses.The AAstV particles isolated from single positive samples appear spherical shape,non-enveloped and 20-80 nm minsize.Two types of virus particles which with spherical shape and diameters of 40-100 and 20-40 nm can be isolated from the negative samples.The virus inoculation results show that the goose embryos can be led to death by clinical GAstV isolates,which with classic histopathological characteristics.Although the GAstV isolates cannot led to death and obvious typical histopathological change in goslings,the vi-ral nucleic acids can be detected in heart,liver,spleen,kidney,intestine and cloacal anal swabs.The above results indicated that there were multiple pathogens co-infection dominated by AAstv in Gosling gout in China,including cross species infections of multiple AAstVs,parvovirus,ARV and suspec-ted novel viruses.Moreover,the GAstV maybe not the only pathogen causing gout in goslings.

Aim To explore the effect of the classical famous prescription Dahuang Zhechong pill(DHZCP)on relieving liver cirrhosis by regulating the stress fiber remodeling mediated by mechanistic signaling pathway and to explore the underlying mechanism.Methods Mice were randomly divided into the control group,model group,DHZCP low-dose group,DHZCP high-dose group,and Colchicine-positive control group.The liver cirrhosis mouse model was constructed by intrap-eritoneal injection of olive oil-solubilized CCl4.HE staining and serologic markers were used to reflect liver injury.Masson staining was used to evaluate collagen deposition in liver tissue.ELISA was applied to detect vasoactive molecules and cancer indicators.Atomic force microscopy was employed to detect liver tissue stiffness.Color Doppler diagnostic instrument was used to assess portal blood flow velocity.Western blot was utilized to detect ROCK2 expression and phosphoryla-tion of YAP,Cofilin,and MLC.Results The liver tis-sues in the model group had obvious inflammatory cell infiltration and collagen deposition,accompanied by significant elevation of serum transaminases and fibrosis indexes.Similarly,vasoactive molecules and cancer in-dicators were elevated,and the mechanoregulatory pro-tein ROCK2 expression and phosphorylation of Cofilin and MLC were elevated,with YAP being strongly de-phosphorylated.Both low and high doses of DHZCP re-versed the pathological changes,serological indices,and inhibited the activation of the stress fiber(SF)re-modeling mechanistic signaling pathway.Conclusion DHZCP effectively ameliorates liver tissue lesions in mice with liver cirrhosis,and its mechanism may be re-lated to the inhibition of SF remodeling mechanistic signaling pathway.

Objective:To evaluate the toxicity of foscarnet sodium injection into the anterior chamber and intravitreal cavity on the cornea and retina.Methods:Thirty-six adult New Zealand White rabbits were randomly divided into control group, intravitreal injection group, and intracameral injection group, with 12 rabbits in each group.In the control group, 0.1 ml of balanced salt solution (BSS) was injected into the vitreous cavity of one eye, and an equal volume of BSS was injected into the anterior chamber of the other eye.In the intracameral injection group and intravitreal injection group, 0.1 ml of sodium foscarnet 1.2 mg was injected into the anterior chamber and vitreous cavity of one eye, respectively.Slit-lamp microscopy, ophthalmoscope, optical coherence tomography (OCT), and in vivo confocal laser scanning microscopy were performed on 3 experimental rabbits from each group on days 1, 7, 14, and 28 after injection.After sacrifice, both eyeballs were removed, and the corneas and retinas were examined using optical microscopy, scanning electron microscopy and transmission electron microscopy to evaluate the toxicity to the cornea and retina comprehensively.The use and care of the animals complied with the ARVO Statement.The study protocol was approved by an Ethics Committee of Peking University Third Hospital (No.IRB00006761-2015197). Results:Slit-lamp microscopy and OCT showed no corneal edema, intraocular inflammation, or other abnormalities in the intravitreal injection and control groups.Mild corneal edema was observed in intracameral injection group 1 day after injection, which resolved 7 days after injection. In vivo confocal laser scanning microscopy revealed normal hexagonal corneal endothelial cell morphology in the intravitreal injection and control groups.There was no significant difference in endothelial cell density at baseline and 1, 7, and 14 days after injection among the three groups ( Fgroup=1.21, P=0.32; Ftime=1.21, P=0.32).Light microscopy revealed no obvious corneal abnormalities.On days 1 and 7 after injection, retinal nerve fiber layer vacuolization and inflammatory cell infiltration were observed in the intravitreal injection and control groups.In the intravitreal injection of BSS group, inflammatory cell infiltration occurred in the retina without vacuolization 1 day after injection.There were no structural changes in the photoreceptor layer, and the nuclear layer was well-organized.Scanning electron microscopy showed no significant abnormalities in the corneal endothelium in the intravitreal injection group 1 day after injection.In the intracameral injection group, a large number of inflammatory cells were deposited and adhered to the corneal endothelium 1 day after injection and disappeared 7 days after injection.Transmission electron microscopy revealed that in the intravitreal injection group, 1 day after injection swelling of corneal endothelial cells, dilatation of the endoplasmic reticulum, and partial mitochondrial swelling were observed, which normalized 14 days after injection and vacuolization was present in the retina and interstitial fluid accumulation persisted until the 28 days after injection.In the intracameral injection group, swollen mitochondrial and endoplasmic reticulum of corneal endothelial cells was observed and resolved by 14 days after injection.However, structural abnormalities in the membranous discs of the photoreceptor outer segments and interstitial fluid accumulation in the optic nerve fiber layer persisted 1 day after injection and did not fully recover 28 days after injection. Conclusions:Intracameral intravitreal and injection of foscarnet sodium have transient toxic effects on the retina, which gradually weaken over time.Intracameral injection of foscarnet sodium was more toxic to corneal endothelial cells than intravitreal injection.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.
