Objective To explore the application values of different detection methods in monitoring the decline pattern of syphilis-spe-cific antibody in the non-congenital syphilis children.Methods A total of 80 non-congenital syphilis children were included in the study.The serum specimens were collected after birth,and the syphilis-specific antibodies were detected using electrochemilumines-cence immunoassay(ECLIA),western blotting(WB),treponema pallidum particle agglutination assay(TPPA),enzyme-linked im-munosorbent assay(ELISA),and toluidine red unheated serum test(TRUST).Follow-up was conducted every three months until the positive results of ELISA and TRUST turned to negative.Results The results of ECLIA showed that the syphilis-specific antibody lev-els in the non-congenital syphilis children declined to 25％of the level at birth within 2 to 3 months,and the rate of decline was inde-pendent of the initial concentration.WB analysis indicated that the specific IgG bands in non-congenital syphilis children at birth were consistent with those of their mother,and the sequence of specific antibodies decline was as follows:TPN47,TPN15,TPN45,and TPN17.Due to methodological limitations,the absorbance values of ELISA showed no significant change during the first three months after birth when high concentrations of antibodies were present in the samples,but it showed high sensitivity in the detection for the samples with low-concentration of syphilis antibodies.The detection rates of ECLIA,TPPA,and WB were compared by using ELISA as the reference method.At birth,the detection rates of syphilis antibodies were 100％,100％,and 90％,respectively.In 3 months after birth,the detection rates were 100％,100％,and 75％.In 6 months after birth,,they were 100％,46％,and 15％.In 9 months after birth,they were 83％,33％,and 0％.The positive rate of TRUST was 17.5％at birth.and turned to negative in 3 month of follow-up.Conclusion Syphilis specific IgG antibodies may fully transferred to the fetus and decline in a predictable pattern after birth.The comprehensive analysis for the results of the four methods suggested that dynamic detection using ECLIA method could be used to pre-dict the risk of non-congenital syphilis or terminate the follow-up at 3 months,while the seroconversion detected by WB was earlier than that by TPPA,while ELISA required the longest follow-up period.

Objective:To evaluate the predictive value of simplified geriatric assessment (sGA) in elderly Chinese patients diagnosed with diffuse large B-cell lymphoma (DLBCL) .Methods:It retrospectively analyzed the relationships of sGA with the clinical characteristics, outcome, and prognosis of 219 patients aged ≥60 years who were newly diagnosed with DLBCL at six hospitals in Jiangsu province between January 2018 and December 2022.Results:The median age of 219 patients was 68 years (60-87 years). According to the sGA system criteria, 101 (46.1%), 103 (47.0%), and 15 (6.8%) elderly patients with DLBCL were categorized as fit, unfit, and frail, respectively. The most common adverse reactions after chemotherapy were hematologic, and the incidence of grade >2 hematologic adverse reactions was similar among the three groups (47.5% vs 41.7% vs 46.7%, respectively; χ2=0.712, P=0.700). Compared with the fit and unfit groups, the frail group showed tendencies toward for higher proportions of grade >2 gastrointestinal, pulmonary, and infectious adverse reactions ( P>0.05 for all). The fit, unfit, and frail groups had respective remission rates of 74.3%, 46.6%, and 20.0% ( χ2=25.249, P<0.001) ; disease progression rates of 5.9%, 11.7%, and 26.7% ( χ2=6.763, P<0.05) ; 2-year overall survival rates of 92.1% (95% CI 86.6% to 97.9%), 77.6% (95% CI 69.5% to 86.6%), and 70.1% (95% CI 49.4% to 99.6%) ( P<0.05) ; and 2-year progression-free survival rates of 76.8% (95% CI 67.0% to 84.8%), 69.7% (95% CI 61.8% to 82.0%), and 65.7% (95% CI 53.3% to 100%) ( P=0.399) . Conclusion:sGA can effectively predict treatment adverse effects and efficacy, disease progression, and long-term survival in elderly DLBCL.

Objective:To explore the long-term effects of intravascular ultrasound (IVUS) guidance on patients with acute coronary syndrome (ACS) undergoing drug-eluting stents (DES) implantation.Methods:Data used in this study derived from ULTIMATE trial, which was a prospective, multicenter, randomized study. A total of 1 448 all-comer patients were enrolled between 2014 August and 2017 May. Primary endpoint of this study was target vessel failure (TVF) at 3 years, including cardiac death, target-vessel-related myocardial infarction, and clinically-driven target vessel revascularization.Results:ACS was present in 1 136 (78.5%) patients, and 3-year clinical follow-up was available in 1 423 patients (98.3%). TVF in the ACS group was 9.6% (109/1 136), which was significantly higher than 4.5% (14/312) in the non-ACS group (log-rank P=0.005). There were 109 TVFs in the ACS patients, with 7.6% (43/569) TVFs in the IVUS group and 11.6% (66/567) TVFs in the angiography group (log-rank P=0.019). Moreover, patients with optimal IVUS guidance were associated with a lower risk of 3-year TVF compared to those with suboptimal IVUS results (5.4% (16/296) vs. 9.9% (27/273),log-rank P=0.041). Conclusions:This ULTIMATE-ACS subgroup analysis showed that ACS patients undergoing DES implantation were associated with a higher risk of 3-year TVF. More importantly, the risk of TVF could be significantly decreased through IVUS guidance in patients with ACS, especially in those who had an IVUS-defined optimal procedure.

Objective To analyze the current patient satisfaction levels and their influencing factors from the perspective of medical experience in private rehabilitation hospitals in Chongqing.This analysis aimed to provide references for these hospitals to improve the quality of medical services.Methods A questionnaire survey of 467 inpatients from three private rehabilitation hospitals in Chongqing was conducted,using convenience sampling.The x2 test and logistic regression analysis were used to i-dentify factors influencing patient satisfaction.Results The overall satisfaction rate of inpatient care was 78.6％,with an aver-age satisfaction score of 3.84±0.52.The complaint and advice service scored the higher,while logistics and environmental serv-ice and rehabilitation treatment service were assessed with lower scores.Regression analysis showed that the per capita monthly household income ranged between 2 001 and 4 000 yuan(OR=0.221,95％CI:0.077-0.635),and between 4 001 and 6 000 yuan(OR=0.296,95％CI:0.125-0.700).Additionally,out-of-pocket payment(OR=4.198,95％CI:1.035-17.027),and others payment methods,including commercial insurance(OR=9.591,95％CI:1.767-52.049)were identified as influential factors.Conclusion Inpatients'overall satisfaction with their medical experience is acceptable,but still has considerable room for improvement.It is recommended that a multidimensional approach be adopted to improve patient satisfaction.

ObjectiveTo observe the effect of bilateral sequential repetitive transcranial magnetic stimulation on the motor function of upper limbs in stroke patients. MethodsFrom December, 2020 to December, 2022, 62 stroke inpatients in the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine were included. They were randomly divided into control group (n = 31) and observation group (n = 31). Both groups accepted conventional medicine and rehabilitation, as well as electroacupuncture antagonistic muscle therapy. Before electroacupuncture, the observation group acceped low-frequency repetitive transcranial magnetic stimulation at primary motor cortex (M1) on the healthy side, followed by intermittent theta burst stimulation at M1 on the affected side, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Barthel Index (MBI) and modified Ashworth Scale (MAS), and motor evoked potential (MEP) latency was compared before and after treatment. ResultsOne patient dropped down in the observation group, and no adverse event happened. After treatment, the scores of FMA-UE and MBI significantly increased (|t| > 9.953, P < 0.001), and the score of MAS and the latency of MEP significantly decreased (|t| > 5.043, P < 0.001) in both groups; while all of them were better in the observation group than in the control group (|t| > 2.237, P < 0.05). ConclusionBilateral sequential repetitive transcranial magnetic stimulation can effectively promote the recovery of upper limb motor function in stroke patients.

ObjectiveUsing multi-omics technology， we conducted the present study to determine whether dexamethasone has therapeutic effect on pneumonia rats through the regulation of intestinal flora and metabolites. MethodsTotally 18 Sprague-Dawley rats were randomly divided into 3 groups （n = 6 each）： Control group， Model group and Dexamethasone （Dex） group. Lipopolysaccharide （LPS） was continuously injected intraperitoneally into rats at a dose of 4 mg/kg for 7 days to induce pneumonia except the Control group. Then the Dex group was given Dex at a dose of 2 mg/kg via oral gavage for 12 days， and both the other two groups received continuously equal volume of sterile PBS buffer for 12 days. On the 19th day， lung， plasma， feces and intestinal contents of rat were collected. Hematoxylin-eosin （H&E） staining and Bio-plex suspension chip system were applied to evaluate the effect of Dex on pneumonia. Furthermore， metagenomic sequencing and UPLC-Q-TOF-MS/MS technology were employed to determine the intestinal flora and metabolites of rats， respectively. ResultsH&E staining results showed that the lung tissue of the Model group was infiltrated with inflammatory cells， the alveolar septum was increased， alveolar hemorrhage， and histological lesions were less severe in Dex group than in the model group. The levels of 3 inflammatory cytokines including TNF-α （P < 0.000 1）， IL-1α （P = 0.009 6） and IL-6 （P < 0.000 1） in the Model group were increased compared with the Control group， while Dex treatment reduced the levels of the three inflammatory factors. Taken together， Dex treatment effectively reversed the features of pneumonia in rats. Metagenomic analysis revealed that the intestinal flora structure of the three groups of rats was changed. In contrast with the Model group， an increasing level of the Firmicutes and an elevated proportion of Firmicutes/Bacteroidetes were observed after Dex treatment. Dex-treated rats possessed notably enrichment of Bifidobacterium， Lachnospiraceae and Lactobacillus. Multivariate statistical analysis showed a great separation between Model group and Dex group， indicating metabolic profile changes. In addition， 69 metabolites （P < 0.05） were screened， including 38 up-regulated in the Model group and 31 elevated in the Dex group， all of which were mainly involved in 3 metabolic pathways： linoleic acid metabolism， tryptophan metabolism and primary bile acid biosynthesis. ConclusionsIn summary， we demonstrate the beneficial effects of Dex on the symptoms of pneumonia. Meanwhile， integrated microbiome-metabolome analysis reveals that Dex improves LPS-induced pneumonia in rats through regulating intestinal flora and host metabolites. This study may provide new insights into the mechanism of Dex treatment of pneumonia in rats.

Objective:To analyze the research hotspots and frontiers in the training of health management talents in China based on knowledge mapping.Methods:The literature related to talent training in health management was retrieved from the databases of CNKI, Wanfang Data, and VIP Journals from 2007 to 2022. The keywords used for retrieval included “health management” “curriculum system” “health manager” “evaluation system” “health service and management” and “talent training”. The time distribution of the literature was analyzed using Excel. Bibliometric analysis was conducted to visually analyze the research in health management talent training, focusing on authorship and collaboration, research institutions, high-frequency keywords, and research hotspots. A knowledge map was created to outline the research framework.Results:A total of 378 journal articles were retrieved. Over the past decade, there has been an overall increasing trend in the number of research publications related to health management talent training. The highest number of articles was published in 2021 (63 articles). In terms of spatial distribution, highly productive authors were relatively concentrated, and research institutions were mostly universities, with Hangzhou Normal University having the highest number of publications (14 articles). The research hotspots included health managers, practice teaching modes, cross-cultivation, and discipline construction. The research frontiers concentrated on talent training modes, health service and management professions, talent demand, and curriculum system construction.Conclusions:In the past decade, health management talents training in China has received more attention and importance. However, there is limited exchange and cooperation among authors and research institutions, and the research hotspots continue to extend in the direction of specialization and diversification. The transformation from vocational education to academic education and strengthening professional construction are the frontiers of the research.
