ObjectiveTo investigate the functional role and underlying molecular mechanisms of fumarylacetoacetate hydrolase （FAH） in the progression of glioblastoma （GBM）. MethodsDifferential expression analysis was performed on the TCGA-GBM， GSE4290， and GSE116520 datasets. Weighted gene co-expression network analysis （WGCNA） was used to identify key modules， and Cox regression and risk modeling were used to screen prognostic genes. Immune infiltration analysis of prognostic genes was carried out by using single-cell RNA sequencing panels. The clinical expression signature of FAH in GBM was analyzed in the TCGA and HPA databases. The functional role of FAH was validated by in vitro and in vivo experiments， and pathway analysis was performed to explore the underlying mechanisms. ResultsA total of 152 overlapping genes were identified across the three GBM datasets （P<0.05）. WGCNA revealed that the turquoise module was most strongly associated with tumor purity， stromal score， immune score， and ESTIMATE score （P<0.001）. Compared with normal tissues， three prognostic genes （CTSD， FAH， and THBD） were upregulated in GBM and correlated with immune infiltration （P<0.05）. FAH mRNA and protein levels were elevated in GBM tissues relative to normal tissues， and its expression was significantly associated with age stratification and TP53 mutation （P<0.05）. CCK-8 assay results showed that， compared with the shNC group， the proliferative activity of GBM cells in the shFAH group was reduced （P<0.001）. Transwell migration and invasion assays demonstrated that， relative to the shNC group， the numbers of migrated and invaded cells in the shFAH group decreased （P<0.05）. Western blot analysis revealed that the protein expression levels of PI3K， p-AKT， and p-mTOR in the shFAH group decreased compared with those in the shNC group （P<0.05）. In vivo subcutaneous xenograft experiments further confirmed that tumor volume and weight significantly decreased in the shFAH group compared with the shNC group （P<0.001）. ConclusionFAH promotes GBM progression by activating the PI3K/AKT/mTOR signaling pathway and may serve as a potential therapeutic target for GBM.

Objective: To investigate the status of salt-restriction spoons use among residents in Zhejiang Province, so as to provide evidence for optimizing salt-reduction intervention strategies and preventing chronic disease. Methods: Residents aged 18-69 from five counties (cities/districts) in Zhejiang Province were selected using a multi-stage stratified random sampling method. Demographic characteristics, dietary habits, and salt-restriction spoons use were collected using questionnaires. The rate of salt-restriction spoons use and correct rate of salt-restriction spoons use were analyzed. Factors affecting salt-restriction spoons use among residents were analyzed by multivariable logistic regression model. Results: Totally 7 601 questionnaires were allocated, and 7 509 valid questionnaires were recovered, with an effective recovery rate of 98.79%. The respondents included 3 744 males (49.86%) and 3 765 females (50.14%). The mean age was (44.81±14.03) years. The rate of salt-restriction spoons use was 11.97%, the correct rate of salt-restriction spoon use was 52.73%. Multivariable logistic regression analysis showed that rural (OR=0.851, 95%CI: 0.731-0.991), education level of primary school and below (illiterate or semi-literate, OR=0.269, 95%CI: 0.172-0.420; primary school, OR=0.595, 95%CI: 0.436-0.811), and excessive dietary salt intake (OR=0.718, 95%CI: 0.559-0.922) were inhibiting factors for salt-restriction spoons use among residents; physical exercise (OR=1.581, 95%CI: 1.362-1.836) and received health education on a low-salt diet (OR=2.082, 95%CI: 1.790-2.421) were promoting factors for salt-restriction spoons use among residents. Conclusions The rate of salt-restriction spoons use among residents in Zhejiang Province was relatively low, primarily influenced by region, educational level, physical activity, dietary salt intake, and health education on a low-salt diet. It is recommended that propose a multi-component intervention strategy centered on skill enhancement and health education, delivered through progressive staged implementation, to promote sustained adoption of salt-restriction spoons among residents.

OBJECTIVE To analyze the clinical characteristics of the 12 patients tested with Candida auris in a three-A hospital so as to provide guidance for prevention and control of nosocomial C.auris infection.METHODS The specimens sources and departments where the C.auris strains were isolated as well as the drug resistance were retrospectively collected from Zhongda Hospital Affiliated to Southeast University between Sep.2023 and Jun.2024.The clinical characteristics of the patients with C.auris infection were summarized.The epidemiological survey was conducted for the possibility of its transmission in hospitals,and the corresponding modified preven-tion measures were put forward.RESULTS Among the 12 patients who were tested with C.auris,10 were male,and 2 were female;the age ranged between 21 and 92 years old.Most of the patients were complicated with multi-ple underlying diseases and had the history of repeated hospitalization as well as the history of invasive operation procedures such as tracheotomy,urinary catheterization,gastric tube indwelling and venoarterial catheterization;in the meantime,other multidrug-resistant organisms(MDROs)and fungi were tested in those patients,and the patients used multiple types of antibiotics.Totally 16 strains of C.auris were isolated from the 12 patients with C.auris tested,62.50％(10/16)of which were isolated from urine specimens,18.75％(3/16)were isolated from sputum specimens,and 6.25％(1/16)were isolated from deep venous catheter,tissue biopsy and wound swab specimens.All of the 16 strains of C.auris were resistant to fluconazole and sensitive to caspofungin;4 strains were resistant to amphotericin B.Totally 2 patients had Candida auris infection,one was pulmonary infection,and the other was urinary tract infection,and the infection rate was 16.67％;both patients were cured.There were 10 cases of colonization,and the colonization rate was 83.33％.The result of epidemiological survey indicated that the C.auris that was tested in the No.8 patient may originate from the No.4 patient who carelessly brought from outside the hospital due to poor implementation of standardized prevention measures.CONCLUSIONS The patients tested with C.auris usually have complicated medical backgrounds.Although the colonized C.auris strains are dominant among the strains in the hospital,the related departments need to intensify the implementation of pre-vention measures so as to prevent the transmission of C.auris and pay special attention to the early identification and management of imported pathogens.

Objective:To investigate the cortical activation characteristics of patients with post-stroke foot drop during task-oriented ankle rehabilitation robot training using functional near-infrared spectroscopy(fNIRS).Method:Twenty patients with post-stroke foot drop were recruited.A 51-channel fNIRS system were used to measure changes in oxygenated hemoglobin(HbO2)in the cortical regions during task-oriented ankle rehabilita-tion robot training.The regions of interest(ROIs)included the bilateral dorsolateral prefrontal cortex(DLP-FC),primary motor cortex(M1),primary somatosensory cortex(S1),premotor area and supplementary mo-tor area(pSMA),and inferior frontal gyrus(IFG).Data processing and statistical analysis were conducted us-ing MATLAB(R2021b)and SPSS 25.0 software.Result:Significant cortical activation was observed in channels 19,26,28,29,35,36,39,42,and 48(P＜0.05)during task-oriented ankle rehabilitation robot training in patients with post-stroke foot drop.Based on the channel-to-brain region registration,significant activation was noted in the bilateral pSMA,bilateral DLPFC,unaffected side S1,and unaffected side IFG's area.Conclusion:Task-oriented ankle rehabilitation robot training can lead to increased cortical activation in pa-tients with post-stroke foot drop,which may represent a potential neural mechanism underlying its therapeutic effects.

Objective To explore the clinical effect and mechanism of Shenqi Shiyiwei granules(SQSYW)on improving colorectal cancer anemia.Methods Through database and network pharmacology analysis,the potential targets and core genes of SQSYW in the treatment of colorectal cancer anemia were obtained.The potential gene targets were analyzed by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes.A total of 80 patients with colorectal cancer anemia admitted in Sichuan Provincial Hospital of Integrated Traditional Chinese and Western Medicine were selected as subjects,according to the treatment plan,they were divided into experimental group(n=40)and control group(n=40).Control group received standard Western medical treatment including subcutaneous erythropoietin injections,while experimental group received additional administration of SQSYW on the base of control group's treatment regimen.Effective treatment rates,TCM symptom score,hemoglobin levels,and red blood cell counts were compared between two groups.Results Five key active ingredients,10 core targets and 30 main pathways were identified through pharmacological screening.Red blood cell count,hemoglobin,TCM syndrome and overall western medicine efficacy were better in experimental group than in control group(P＜0.05).Conclusion SQSYW can treat colorectal cancer anemia through multiple components,multiple targets and multiple pathways.The treatment effect of colorectal cancer anemia combined with SQSYW is better than that of simple western medicine.

BACKGROUND:The cryopreservation technology enables tissues/cells to be stored for a long time in a low-temperature environment while maintaining the integrity of their activity and function,which is of great significance for the construction of cell therapy,tissue engineering and biological sample banks.Cryoprotective agents often contain dimethyl sulfoxide and serum.To avoid the toxic side effects of dimethyl sulfoxide,the complexity of serum components and immune responses,although some finished cryoprotective agents have been marketed,they are faced with many difficulties such as high cost and limited application.Therefore,there is an urgent need to develop a cryoprotective agent with clear components and the ability to solve the above problems.OBJECTIVE:To evaluate the effects of a novel cryoprotectant on cryopreservation efficiency of different tissue and cell sources.METHODS:By applying the novel cryoprotectant as an experimental group with the commercially available and widely used cryoprotectant(control group)to umbilical cord Wharton's jelly tissue,umbilical cord mesenchymal stem cells,umbilical cord blood/peripheral blood mononuclear cells,NK and CIK cells,comparative analyses were conducted in terms of cell morphology,number,viability,surface markers,differentiation potential,and cell-killing toxicity assay before cryopreservation and after resuscitation thawing.We confirmed the cryopreservation effect of the new cryoprotectant and its potential application value.RESULTS AND CONCLUSION:(1)The novel cryoprotectant facilitated the normal growth of cryopreserved Wharton's jelly tissue upon recovery,exhibiting mesenchymal stem cell morphology.No significant differences were observed between the experimental and control groups in terms of cell recovery rate,surface markers,and differentiation potential.(2)There was no significant difference in the number and viability of cells between the experimental group and the control group after cryopreservation of cord blood/peripheral blood mononuclear cells,and the cryo-resuscitated cell numbers and viability of derived NK cells/CIK cells did not show significant difference between the experimental and control groups.(3)For NK cells derived and differentiated from cord blood/peripheral blood mononuclear cells,there was no significant difference in the proportion of CD56+CD16+cell subpopulations between the experimental group and the control group.For CIK cells derived and differentiated from cord blood/peripheral blood mononuclear cells,there was no significant difference in the proportions of CD3+CD8+and CD3+CD56+cell subpopulations between the experimental group and the control group.(4)In terms of cytotoxicity testing,when the effective-target ratio of immune cells and melanoma cell line Mel624 was 20:1,whether it was NK cells/CIK cells derived from cord blood or peripheral blood mononuclear cells,there was no significant difference in the tumoricidal activity of cells between the experimental group and the control group.These findings suggest that the novel cryoprotectant can replace existing commercially available and widely used cryoprotectants,and is applicable to Wharton's jelly tissue,umbilical cord mesenchymal stem cells,umbilical cord blood/peripheral blood mononuclear cells,as well as NK and CIK cells,providing a solid technical foundation for the scaling,standardization,and commercialization of universal cryoprotectants.
