Anti-tumor traditional Chinese medicine has a long history of clinic application, in which the star molecules have always been the hotspot of modern drug research, but they are limited by the solubility, stability, targeting, bioactivity or toxicity of the monomer components of traditional Chinese medicine anti-tumor star molecules and other pharmacokinetic problems, which hinders the traditional Chinese medicine anti-tumor star molecules for further clinical translation and application. Currently, the nanosystems prepared by supramolecular technologies such as molecular self-assembly and nanomaterial encapsulation have broader application prospects in improving the anti-tumor effect of active components of traditional Chinese medicine, which has attracted extensive attention from scholars at home and abroad. In this paper, we systematically review the research progress in preparation of supramolecular nano-systems from anti-tumor star molecule of traditional Chinese medicine, and summarize the two major categories and ten small classes of carrier-free and carrier-based supramolecular nanosystems and their research cases, and the future development direction is put forward. The purpose of this paper is to provide reference for the research and clinical transformation of using supramolecular technology to improve the clinical application of anti-tumor star molecule of traditional Chinese medicine.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.

Tyrosine kinase inhibitors(TKIs)have emerged as the first-line small molecule drugs in many cancer therapies,exerting their effects by impeding aberrant cell growth and proliferation through the mod-ulation of tyrosine kinase-mediated signaling pathways.However,there exists a substantial inter-individual variability in the concentrations of certain TKIs and their metabolites,which may render patients with compromised immune function susceptible to diverse infections despite receiving theo-retically efficacious anticancer treatments,alongside other potential side effects or adverse reactions.Therefore,an urgent need exists for an up-to-date review concerning the biological matrices relevant to bioanalysis and the sampling methods,clinical pharmacokinetics,and therapeutic drug monitoring of different TKIs.This paper provides a comprehensive overview of the advancements in pretreatment methods,such as protein precipitation(PPT),liquid-liquid extraction(LLE),solid-phase extraction(SPE),micro-SPE(p-SPE),magnetic SPE(MSPE),and vortex-assisted dispersive SPE(VA-DSPE)achieved since 2017.It also highlights the latest analysis techniques such as newly developed high performance liquid chromatography(HPLC)and high-resolution mass spectrometry(HRMS)methods,capillary electro-phoresis(CE),gas chromatography(GC),supercritical fluid chromatography(SFC)procedures,surface plasmon resonance(SPR)assays as well as novel nanoprobes-based biosensing techniques.In addition,a comparison is made between the advantages and disadvantages of different approaches while pre-senting critical challenges and prospects in pharmacokinetic studies and therapeutic drug monitoring.

Objective To summarize the clinical characteristics of children with drug-induced hypersensitivity syndrome(DIHS)complicated with herpesvirus reactivation,and to promote the early and accurate identification,diagnosis,and treatment of DIHS in children.Methods The medication history,clinical manifestations,treatment,and prognosis of 12 children confirmed DIHS complicated with herpesvirus reactivation in Guangzhou Women and Children's Medical Center between January 2018 and March 2023 were retrospectively analyzed.The changes in hematological parameters,inflammatory indexes,and hepatic and renal function within 5 d before the eruption,5 d,and 6-10 d after eruption were compared.Results Of the 12 patients,the male-to-female ratio was 5∶1,with a median age of 27(interquartile range 20.50-34.75)months.Two or more antibiotics were used at least two to six weeks before onset,with a combination of 3 or more antibiotics in 7 children,and a combined or sequential application of 2 antibiotics in 5 children.The antibiotics included cephalosporins(n=12),semisynthetic penicillins(n=5),vancomycin(n=4)and azithromycins(n=7).All 12 patients presented fever,rashes,and multiple organ involvement.The rashes were red maculopapules in the early stage and then gradually developed into massive fusion exceeding 50%of the whole body.Among them,seven children were accompanied by facial edema,and two had purplish-red facial rashes.11 children suffered from exfoliative dermatitis in the later stage.12 children presented obviously enlarged lymph nodes.Liver involvement was the most common(100%,simple increase of transaminase in four children,cholestasis in six children,and hepatic failure in two children),and lung involvement was found in nine children.Laboratory examination showed no significant increase in leukocytes or eosinophils within 5 d before the eruption,but low levels of atypical lymphocytes.After the eruption,leukocytes,eosinophils,and atypical lymphocytes increased progressively.Inflammatory indexes of hypersensitive C-reactive protein(CRP),procalcitonin(PCT)increased dramatically before and after the eruption.All the children received intravenous immunoglobulin(IVIG)and methylprednisolone,two children were given antiviral therapy,and nine children were treated with multiple plasma exchanges.After treatment,nine children were cured,one developed immune reconstitution syndrome,and two died of hepatic failure.Conclusions Antibiotics are common allergenic drugs for DIHS in children.Its clinical manifestations include fever and rashes,accompanied by multiple organ involvement,such as the liver and lung.When leukocytes,eosinophils,and atypical lymphocytes are progressively elevated after the eruption,DIHS should be highly suspected,herpesvirus activation should be monitored,medication history should be traced,and early active immunotherapy and antiviral therapy should be conducted if necessary.

Objective:Evaluate the effects of brief mindfulness meditation training on improving negative e-motions,mindfulness attention awareness,and sleep quality in patients after percutaneous coronary intervention(PCI)for coronary heart disease.Methods:Eighty-four patients with coronary heart disease after PCI admitted to the cardiology department were selected.According to the principle of simple randomization,they were divided into an intervention group of 42 cases and a control group of 42 cases.The Self Rating Anxiety Scale/Self Rating De-pression Scale,Mindfulness Attention Awareness Scale,and Pittsburgh Sleep Quality Index Scale were used as eval-uation indicators before and after intervention.Results:The difference in total scores of anxiety,depression,and mindfulness attention awareness before and after intervention in the intervention group was higher than that in the control group(P＜0.05).The difference in total sleep score,sleep quality,time to fall asleep,sleep duration,use of hypnotic drugs,daytime dysfunction,and total sleep score before and after intervention was higher than that of the control group(P＜0.05).Conclusion:It suggests that brief mindfulness meditation training could alleviate negative emotions in patients with coronary heart disease after PCI,improve mindfulness awareness,and improve sleep quali-ty.

Less invasive transcatheter tricuspid therapies are optimal alternative for surgery in high-risk individuals with severe symptomatic tricuspid regurgitation on medical therapy. Various techniques are available with Transcatheter Edge-to-Edge Repair (TEER) having the greatest experience worldwide. When the coaptation gap becomes too large for TEER, caval valve implantation (CAVI) emerge as a better option. We described a series of 4 patients who underwent CAVI with the TricValve system and periprocedural computed tomography angiography imaging for the purpose of TricValve sizing. There were few procedural complications, with significant improvements in New York Heart Association functional class and right ventricular function post-procedure.

Background/Aims: The performance of machine learning (ML) in predicting the outcomes of patients with hepatocellular carcinoma (HCC) remains uncertain. We aimed to develop risk scores using conventional methods and ML to categorize early-stage HCC patients into distinct prognostic groups. Methods: The study retrospectively enrolled 1,411 consecutive treatment-naïve patients with the Barcelona Clinic Liver Cancer (BCLC) stage 0 to A HCC from 2012 to 2021. The patients were randomly divided into a training cohort (n=988) and validation cohort (n=423). Two risk scores (CATS-IF and CATS-INF) were developed to predict overall survival (OS) in the training cohort using the conventional methods (Cox proportional hazards model) and ML-based methods (LASSO Cox regression), respectively. They were then validated and compared in the validation cohort. Results: In the training cohort, factors for the CATS-IF score were selected by the conventional method, including age, curative treatment, single large HCC, serum creatinine and alpha-fetoprotein levels, fibrosis-4 score, lymphocyte-tomonocyte ratio, and albumin-bilirubin grade. The CATS-INF score, determined by ML-based methods, included the above factors and two additional ones (aspartate aminotransferase and prognostic nutritional index). In the validation cohort, both CATS-IF score and CATS-INF score outperformed other modern prognostic scores in predicting OS, with the CATSINF score having the lowest Akaike information criterion value. A calibration plot exhibited good correlation between predicted and observed outcomes for both scores. Conclusions Both the conventional Cox-based CATS-IF score and ML-based CATS-INF score effectively stratified patients with early-stage HCC into distinct prognostic groups, with the CATS-INF score showing slightly superior performance.

Lysosomal dysfunction plays an important role in neurodegenerative diseases, including Parkinson’s disease (PD) and possibly Parkinson-plus syndromes such as progressive supranuclear palsy (PSP). This role is exemplified by the involvement of variants in the GBA1 gene, which results in a deficiency of the lysosomal enzyme glucocerebrosidase and is the most frequently identified genetic factor underlying PD worldwide. Pathogenic variants in the SMPD1 gene are a recessive cause of Niemann–Pick disease types A and B. Here, we provide the first report on an association between a loss-of-function variant in the SMPD1 gene present in a heterozygous state (p.Pro332Arg/p.P332R, which is known to result in reduced lysosomal acid sphingomyelinase activity), with PSP-Richardson syndrome in three unrelated patients of Chinese ancestry.

AIM: To investigate the effect of repeated intravitreal injection of anti-vascular endothelial growth factor(VEGF)on the vitreomacular interface(VMI)and its related risk factors in patients with diabetic macular edema(DME).METHODS: The clinical data of 31 patients(55 eyes)with DME who received intravitreal injections of Conbercept(3+PRN)in the ophthalmology department of the First People's Hospital of Zunyi from January 2018 to December 2021 were analyzed retrospectively. There were 9 cases(13 eyes)in the group that has changes in VMI and 22 cases(42 eyes)in the other group that has no changes in VMI. The best corrected visual acuity(BCVA), central retinal thickness(CRT), and central choroidal thickness(CCT)of the two groups were compared, and the risk factors of VMI change were analyzed.RESULTS: The patients were followed up for an average of 9.58±8.32mo, received an average of 4.07±2.17 times of anti-VEGF therapy, and the number of intravitreal injections in VMI changed group was more than that in VMI unchanged group(5.77±2.09 times vs. 3.55±1.93 times, P=0.001). At the last follow-up, compared with before treatment, the BCVA of both patients improved significantly after treatment(both P<0.05), while CCT had no significant change(both P>0.05). CRT of patients in the VMI unchanged group decreased significantly(P=0.039), but there was no significant change in patients of VMI changed group(P=0.627). Logistic regression analysis showed that BCVA was a risk factor for VMI change before treatment(P=0.049, OR=6.210, 95%CI 1.006～38.346).CONCLUSIONS: The VMI of DME patients may change during repeated intravitreal injections of anti-VEGF drugs. The worse the BCVA before treatment, the higher the risk of change in VMI, and the patients with VMI change have a poor response to anti-VEGF treatment.
