Objective To investigate the relationship between serum insulin-like growth factor 1 (IGF1) and metabolic syndrome ( MS) . Methods Four hundred and sixty-five subjects were enrolled and divided into two groups: MS group( n = 255) and non-MS group as control(n = 210). Fasting levels of blood glucose (FBG), insulin (Ins) , C peptide (Cp) , cholesterol (Cho) , triglyceride (TG), lower-density lipoprotein cholesterin ( LDL-C) , higher-density lipoprotein cholesterin ( HDL -C), lipoprotein a (Lpa), serum IGF1, postprandial 2 hours blood glucose (PBG), and BMI were measured in these persons. Results The levels of IGF1, Cp, FBG, PBG, CT, TG, LDL-C, BMI were higher, and HDL-C was lower in MS group than those in non-MS group (all P

The aim of this study is to establish stable transfected cell lines which could produce SPAG4L protein labeled with Myc and His tags in vitro. The open reading frame (ORF) of human SPAG4L was amplified by PCR and the fragments were cloned into eukaryotic expression vector pcDNA3.1/myc-His(-)A. The recombined plasmids of pcDNA3.1/myc-His(-)A/SPAG4L were verified by sequencing and digestion with enzymes. Then, the recombined plasmids were introduced into HeLa cells and screened by G418. Western blotting was performed to detect the expression of SPAG4L and its tags in stable transfected cell lines. SPAG4L and its tags were expressed in the stable cell lines transfected with pcDNA3.1/myc-His(-)A/SPAG4L, but not in the control group. Further study showed that SPAG4L colocalized with the endoplasmic reticulum(ER) marker PDI by immunofluorescence. The stable transfected cell lines established in this study will provide a powerful tool for further studies such as co-immunoprecipitation and pull-down.

Objective To investigate the effects of acute fatigue on the outcome of aged patients with cerebral infarction. Methods The Fatigue Severity Scale was used to investigate the incidence of fa-tigue in 240 elderly patients with acute cerebral infarction,to assess the outcome of the patients at discharge and one year after discharge,and to analyze the effect of acute fatigue on the functional recovery and survival of patients. Results Totally 89 patients (37. 1%) suffered from acute fatigue. Multivariate Logistic regres-sion analysis showed that high admission NIHSS score(OR=2. 472,95%CI= 1. 931-3. 164) and acute post-stroke fatigue(OR=4. 820,95%CI=2. 281~10. 187) were the influencing factors for functional recovery of elderly patients with cerebral infarction at discharge(P<0. 01). High admission NIHSS score( OR=1. 674, 95%CI=1. 411-1. 985),acute post-stroke fatigue( OR=2. 123,95%CI=1. 187-3. 796),mRS score≥ 2 at discharge(OR=9. 822,95%CI=4. 899-19. 693) and recurrence( OR=6. 146,95%CI=2. 596-14. 553) were independent risk factors for functional recovery of elderly patients with cerebral infarction one year after dis-charge ( P<0. 05). Multivariate Cox regression analysis showed that age (OR=1. 096,95% CI=1. 027-1. 169),post-stroke fatigue in acute phase OR=5. 233, 95% CI=1. 051-6. 053) and recurrence ( OR=13. 983,95%CI=2. 821-49. 307) were independent predictors of mortality for elderly patients with cerebral infarction (P<0. 05). Conclusion Fatigue after acute stroke can effect the functional recovery and survival of elderly patients with cerebral infarction.

Objective:To analyze the clinical value of 18F-FDG PET/MR for precise localization of epileptogenic foci in patients with refractory epilepsy. Methods:From February 2019 to December 2021, 81 patients (52 males, 29 females; age (30.0±10.9) years) with refractory epilepsy confirmed in Ruijin Hospital Shanghai Jiao Tong University School of Medicine were retrospectively enrolled. All patients underwent preoperative PET/MR exam, and the possible position of the epileptogenic foci were determined by PET/MR imaging and pre-surgical evaluation, then the stereoelectroencephalography (SEEG) electrodes were implanted. Surgery was performed, and outcome was assessed by using a modified Engel classification two years after surgery. χ2 test was used to compare the detection rates of MRI and PET/MR fusion imaging in localizing epileptogenic foci and the detection rates of epileptogenic foci in temporal lobe epilepsy (TLE) and extratemporal lobe epilepsy (ETLE) by PET/MR. Results:MRI correctly localized seizure foci in 38 patients, with the detection rate of 46.91%(38/81), while PET/MR detected seizure foci in 73 patients, with the detection rate of 90.12%(73/81; χ2=35.05, P<0.001). There were 63 TLE and 18 ETLE patients. The detection rate of PET/MR in localizing seizure foci in TLE patients was 95.24%(60/63), which was significantly higher than that in ETLE patients (13/18; χ2=5.94, P=0.015). After 2 years follow-up, the postoperative efficacy rate of TLE patients with Engel grades Ⅰ-Ⅱ was 76.19%(48/63), which was 13/18 of ETLE patients ( χ2=0.12, P=0.731). Conclusion:Hybrid PET/MR imaging can accurately locate epileptogenic foci, especially for MRI negative lesions, which provides precision imaging information for surgical planning and improves surgical success rate.

Objective:To identify the characteristics of the bone marrow immune microenvironment associated with long-term survival in multiple myeloma (MM) patients.Methods:In the follow-up cohort of patients with newly diagnosed MM and who received “novel agent induction therapy and subsequent autologous stem cell transplantation and immunomodulator maintenance therapy” in the First Affiliated Hospital of Sun Yat-sen University, a cross-sectional study was carried out between August 2019 and May 2020. Using NanoString technology, the RNA expression of 770 bone marrow immune-related markers was compared between 16 patients who had progression-free survival ≥5 years and 5 patients with progressive disease. Among the 16 patients who achieved long-term survival, 9 achieved persistent minimal residual disease (MRD) negative while the other 7 had persistent positive MRD. The functional scores of each kind of immune cells were calculated based on the expression level of characteristic genes, so as to indirectly obtained the proportion of each immune cell subset. The Mann-Whitney U test and the Kruskal Wallis test were used for statistical analysis. Results:The proportion of neutrophils was significantly higher in long-surviving MM patients than in patients with progressive disease [functional scores, 13.61 (13.33, 14.25) vs. 12.93 (12.58, 13.38); Z=2.31, P=0.021]. Among long-surviving patients, those who were MRD-positive had a significantly greater number of mast cells compared with those who were MRD-negative [functional scores, 7.09 (6.49, 8.57) vs. 6.03 (5.18, 6.69); H=2.18, P=0.029]. Compared with patients with progressive disease, four genes (CTSG, IFIT2, S100B, and CHIT1) were significantly downregulated and six (C4B, TNFRSF17, CD70, IRF4, C2, and GAGE1) were upregulated in long-surviving patients. Among long-surviving patients, only gene CMA1 was significantly upgraded, 10 genes (ISG15, OAS3, MX1, IFIT2, DDX58, SIGLEC1, CXCL10, IL1RN, SERPING and TNFSF10) were significantly downregulated in the MRD-positive group compared with that in the MRD-negative group, the first 5 of which are related to the interferon response pathway. Conclusions:The increased neutrophil and mast cell numbers may be related to long-term survival in MM. Interferon signaling activation may be a key bone marrow immune profiling feature for MRD-negative, long-surviving patients with MM.

Objective To explore the potential influencing factors and complex pathways affecting rehabilitation effect for children with autism spectrum disorder(ASD)from the perspective of parental efficacy in doctor-patient communication,and to provide evidence for improving the quality of rehabilitation service for children with ASD. Methods An anonymous face-to-face questionnaire survey was conducted to collect general demographic information of parents of children with ASD at designated rehabilitation institutions in Gansu province.The data included paren-tal efficacy in doctor-patient communication,parental compliance of treatment and children's rehabilitation out-comes were collected.A structural equation model was used to explore the impact mechanism of parental commu-nication efficacy on the rehabilitation outcomes of children with ASD. Results Data from 519 parents at 37 rehabilitation institutions across 13 cities/counties in Gansu province were collect-ed.Significant positive correlations were found between parental efficacy in doctor-patient communication,doc-tor-patient relationships,parental compliance with treatment and rehabilitation outcomes for children with ASD(P＜0.05).Through structural equation model analysis,the standardized direct effect of children with ASD from parents'doctor-patient communication efficacy was 0.151(P=0.023).The mediating effect of doctor-patient rela-tionship and parental compliance with treatment were 0.160(P=0.001)and 0.111(P=0.001),respectively,with a chained mediating effect of 0.035(P=0.001).The pathway"parental efficacy in doctor-patient communica-tion → doctor-patient relationship → ASD child's rehabilitation outcome"accounted for the highest proportion of the total mediating effect,at 52.29%. Conclusion Parental doctor-patient communication efficacy may positively impact on the rehabilitation outcomes of chil-dren with ASD directly,and indirectly through the doctor-patient relationship and parental compliance with treat-ment.Rehabilitation institutions should focus on fostering parental communication skills and enhancing high-quality and humanized rehabilitation services.
