Parkinson's disease is a neurodegenerative disease that mostly occurs in middle-aged and elderly people. It is characterized by progressive loss of dopaminergic neurons in the substantia nigra and aggregation of Lewy bodies, resulting in a series of motor symptoms and non-motor symptoms. Depression is the most important manifestation of non-motor symptoms, which seriously affects the quality of life of patients. Clinicians often use antidepressant drugs to improve the depressive symptoms of patients with Parkinson 's disease, but it is still urgent to solve the problems of drug side effects and drug resistance caused by such methods. Repetitive transcranial magnetic stimulation is a safe and non-invasive neuromodulation technique that can change the excitability of the corticospinal tract, induce the release of dopamine and other neurotransmitters, and further improve the depressive symptoms of patients with Parkinson 's disease. Based on this, this paper discusses and summarizes the research progress on the efficacy and potential mechanism of repetitive transcranial magnetic stimulation for improving depression in Parkinson 's disease at home and abroad, in order to provide reference for related clinical application research.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

Objective:To explore the diagnostic value of transvaginal color Doppler sonography (TVCDS) combined with serum allograft inflammatory factor-1 (AIF-1) and pyruvate kinase M2 type (PKM2) in cervical cancer.Methods:From Jan. 2022 to Jun. 2024, 168 patients with early cervical cancer who visited Taizhou Central Hospital were regarded as the cervical cancer group, and 96 patients with cervical precancerous lesions were regarded as the precancerous lesion group. All patients underwent TVCDS examination to obtain parameters such as peak systolic velocity (PSV), end diastolic velocity (EDV), and resistance index (RI). ELISA method was used to detect serum AIF-1 and PKM2 levels. Kappa test was used to analyze the consistency between different diagnostic methods and pathological results. ROC curve was used to analyze the diagnostic value of serum AIF-1 and PKM2 levels for cervical cancer.Results:The cervical cancer group had manifestly higher proportions of irregular morphology, unclear boundaries, low echo ratio, and levels of PSV, EDV, AIF-1, and PKM2 than precancerous lesion group, and manifestly lower RI than precancerous lesion group ( P<0.05). The consistency analysis between TVCDS diagnosis of cervical cancer and pathological results showed a Kappa value of 0.674 ( P<0.05). The serum levels of AIF-1 and PKM2 in cervical cancer patients with a maximum tumor diameter of ≥ 4 cm, low differentiation, and vaginal infiltration were manifestly higher than those in patients with a maximum tumor diameter of < 4 cm, medium/high differentiation, and non vaginal infiltration ( P<0.05). The AUC of AIF-1 and PKM2 in the diagnosis of cervical cancer was 0.824 and 0.816, respectively, with diagnostic thresholds of 81.21 ng/L and 29.26 ng/mL. The consistency analysis of TVCDS combined with serum AIF-1 and PKM2 in the diagnosis of cervical cancer and pathological results showed a Kappa value of 0.918 ( P<0.05). The negative predictive value, accuracy, and sensitivity of TVCDS combined with serum AIF-1 and PKM2 in the diagnosis of cervical cancer were higher than those of each indicator alone, and the positive predictive value and specificity were higher than those of AIF-1 alone ( P<0.05) . Conclusion:TVCDS combined with serum AIF-1 and PKM2 has high accuracy and sensitivity in the diagnosis of cervical cancer, and their combination can serve as a potential method for clinical diagnosis of cervical cancer.

Objective To investigate the effect of long non-coding ribonucleic acid cancer susceptibility can-didate gene 19(lncRNA CASC19)regulating the microRNA(miR)-490-3p/high mobility group protein A2(HMGA2)axis on the proliferation,migration,and chemotherapy resistance of colorectal cancer(CRC)cells.Methods Human normal colonic epithelial cells(FHC)and CRC cell lines(LOVO,HCT116,SW480)were cultured.LOVO cells were randomly divided into Control group,sh-NC group,sh-CASC19 group,sh-CASC19+anti-NC group and sh-CASC19+anti-miR-490-3p group.The lncRNA CASC19,miR-490-3p and HMGA2 mRNA expression were detected by real-time fluorescence quantitative polymerase chain reaction(qRT-PCR).The relationship between lncRNA CASC19 and miR-490-3p and between miR-490-3p and HM-GA2 were detected by Dual luciferase assay.The cell proliferation ability was detected by cell counting kit-8(CCK-8)assay and colony formation assay.The cell migration ability was detected by cell scratch assay.The cell invasion ability was detected by Transwell assay.The cell metastasis-related proteins(MMP2,MMP9)and HMGA2 protein expression were detected by Western blot assay.The chemotherapy resistance was detec-ted by cisplatin and fluorouracil.Results The lncRNA CASC19 and HMGA2 mRNA expression increased in CRC cell lines,and miR-490-3p expression decreased.The lncRNA CASC19,miR-490-3p and HMGA2 mRNA expression in LOVO cells were the most significant,LOVO cells were selected for subsequent experiments.The dual luciferase assay showed that,after the transfection of lncRNA CASC19 and HMGA2,compared with mimic-NC group,the luciferase activity in miR-490-3p mimic group decreased(P＜0.05).Compared with sh-NC and Control groups,the survival rate,clone number,migration rate,invasion rate,MMP2,MMP9,HMGA2 mRNA and protein expression of LOVO cells in sh-CASC19 group were decreased,and the miR-490-3p ex-pression was increased(P＜0.05).Compared with sh-CASC19 group and sh-CASC19+anti-NC group,the survival rate,clone number,migration rate,invasion rate,MMP2,MMP9,HMGA2 mRNA and protein expres-sion of LOVO cells in sh-CASC19+anti-miR-490-3p group were increased,and the miR-490-3p expression was decreased(P＜0.05).The chemotherapy resistance experiment showed that,compared with Control group,the chemotherapy resistance sensitivity of LOVO cells in sh-CASC19 group increased(P＜0.05).Compared with sh-CASC19 group,the chemoresistance sensitivity of LOVO cells in sh-CASC19+anti-miR-490-3p group was decreased(P＜0.05).In the same group,with the increase of the concentration of fluorou-racil and cisplatin,the cell survival rate gradually decreased(P＜0.05).Conclusion Knockdown of lncRNA CASC19 can regulate miR-490-3 p/HMGA2 signaling pathway,inhibit the proliferation and migration of CRC cells,and increase the sensitivity of chemotherapy resistance.

Background::B-cell maturation antigen (BCMA)-directed chimeric antigen receptor T (CAR-T) therapy yield remarkable responses in patients with relapsed/refractory multiple myeloma (R/RMM). Circulating tumor DNA (ctDNA) reportedly exhibits distinct advantages in addressing the challenges posed by tumor heterogeneity in the distribution and genetic variations in R/RMM.Methods::Herein, the ctDNA of 108 peripheral blood plasma samples from patients with R/RMM at the First Affiliated Hospital, School of Medicine, Zhejiang University was thoroughly investigated before administration of anti-BCMA CAR-T therapy to establish its predictive potential. Flow cytometry is used primarily to detect subgroups of T cells or CAR-T cells.Results::In this study, several tumor and T cell effector-mediated factors were considered to be related to treatment failure by an integrat analysis, including higher percentages of multiple myeloma (MM) cells in the bone marrow ( P = 0.0125), lower percentages of CAR-T cells in the peripheral blood at peak ( P = 0.0375), and higher percentages of CD8 + T cells ( P = 0.0340). Furthermore, there is a substantial correlation between high ctDNA level (>143 ng/mL) and shorter progression-free survival (PFS) ( P = 0.007). Multivariate Cox regression analysis showed that high levels of ctDNA (>143 ng/mL), MM-driven high-risk mutations (including IGLL5 [ P = 0.004], IRF4 [ P = 0.024], and CREBBP [ P = 0.041]), number of multisite mutations, and resistance-related mutation ( ERBB4, P = 0.040) were independent risk factors for PFS. Conclusion::Finally, a ctDNA-based risk model was built based on the above independent risk factors, which serves as an adjunct non-invasive measure of substantial tumor burden and a prognostic genetic feature that can assist in predicting the response to anti-BCMA CAR-T therapy.
