Objective To observe the abnormal brain activity in patients with migraine without aura(MwoA)with MRI.Methods Fifty MwoA patients(MwoA group)and 46 healthy volunteers(control group)were prospectively enrolled.Functional MRI(fMRI)was performed to observe the dynamic regional homogeneity(dReHo)of brain regions,then brain regions with differences of dReHo value between groups were extracted,and correlations with clinical scales were analyzed.Results Compared with control group,dReHo values of surrounding cortex of bilateral calcarine fissure and right middle occipital gyrus increased,of right middle temporal gyrus,right middle frontal gyrus and left cuneus decreased in MwoA group(GRF correction,voxel level all P＜0.005,cluster level all P＜0.05).The weight analysis showed that brain regions with top 3 absolute weight values were surrounding cortex of right calcarine fissure,left cuneus and right middle occipital gyrus.dReHo value of surrounding cortex of left calcarine fissure in MwoA patients was negative correlated with self-rating depression scale(SDS)(r=-0.28,P=0.04).Conclusion Abnormalities in the upward transmission pathway of visual information existed in MwoA patient,especially in surrounding cortex of right calcarine fissure,left cuneus and right middle occipital gyrus.

Background::Prenatal and postnatal factors may have joint effects on cardiovascular health, and we aimed to assess the joint association of birth weight and ideal cardiovascular health metrics (ICVHMs) prospectively in adulthood with incident cardiovascular disease (CVD).Methods::In the UK Biobank, 227,833 participants with data on ICVHM components and birth weight and without CVD at baseline were included. The ICVHMs included smoking, body mass index, physical activity, diet information, total cholesterol, blood pressure, and hemoglobin A1c. The Cox proportional hazards model was used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) in men and women.Results::Over a median follow-up period of 13.0 years (2,831,236 person-years), we documented 17,477 patients with incident CVD. Compared with participants with birth weights of 2.5-4.0 kg, the HRs (95% CIs) of CVD among those with low birth weights was 1.08 (1.00-1.16) in men and 1.23 (1.16-1.31) in women. The association between having a birth weight <2.5 kg and CVD risk in men was more prominent for those aged <50 years than for those of older age ( P for interaction = 0.026). Lower birth weight and non-ideal cardiovascular health metrics were jointly related to an increased risk of CVD. Participants with birth weights <2.5 kg and ICVHMs score 0-1 had the highest risk of incident CVD (HR [95% CI]: 3.93 [3.01-5.13] in men; 4.24 [3.33-5.40] in women). The joint effect (HR [95% CI]: 1.36 [1.17-1.58]) could be decomposed into 24.7% (95% CI: 15.0%-34.4%) for a lower birth weight, 64.7% (95% CI: 56.7%-72.6%) for a lower ICVHM score, and 10.6% (95% CI: 2.7%-18.6%) for their additive interaction in women. Conclusions::Birth weight and ICVHMs were jointly related to CVD risk. Attaining a normal birth weight and ideal ICVHMs may reduce the risk of CVD, and a simultaneous improvement of both prenatal and postnatal factors could further prevent additional cases in women.

Background::Life’s Simple 7, the former construct of cardiovascular health (CVH) has been used to evaluate adverse non-communicable chronic diseases (NCDs). However, some flaws have been recognized in recent years and Life’s Essential 8 has been established. In this study, we aimed to analyze the association between CVH defined by Life’s Essential 8 and risk of 44 common NCDs and further estimate the population attributable fractions (PAFs) of low-moderate CVH scores in the 44 NCDs.Methods::In the UK Biobank, 170,726 participants free of 44 common NCDs at baseline were included. The Life’s Essential 8 composite measure consists of four health behaviours (diet, physical activity, nicotine exposure, and sleep) and four health factors (body mass index, non-high density lipoprotein cholesterol, blood glucose, and blood pressure), and the maximum CVH score was 100 points. CVH score was categorized into low, moderate, and high groups. Participants were followed up for 44 NCDs diagnosis across 10 human system disorders according to the International Classification of Diseases 10th edition (ICD-10) code using linkage to national health records until 2022. Cox proportional hazard models were used in this study. The hazard ratios (HRs) and PAFs of 44 NCDs associated with CVH score were examined.Results::During the median follow-up of 10.85 years, 58, 889 incident NCD cases were documented. Significant linear dose-response associations were found between higher CVH score and lower risk of 25 (56.8%) of 44 NCDs. Low-moderate CVH (<80 points) score accounted for the largest proportion of incident cases in diabetes (PAF: 80.3%), followed by gout (59.6%), sleep disorder (55.6%), chronic liver disease (45.9%), chronic kidney disease (40.9%), ischemic heart disease (40.8%), chronic obstructive pulmonary disease (40.0%), endometrium cancer (35.8%), lung cancer (34.0%), and heart failure (34.0%) as the top 10. Among the eight modifiable factors, overweight/obesity explained the largest number of cases of incident NCDs in endocrine, nutritional, and metabolic diseases (35.4%), digestive system disorders (21.4%), mental and behavioral disorders (12.6%), and cancer (10.3%); however, the PAF of ideal sleep duration ranked first in nervous system (27.5%) and neuropsychiatric disorders (9.9%).Conclusions::Improving CVH score based on Life’s Essential 8 may lower risk of 25 common NCDs. Among CVH metrics, avoiding overweight/obesity may be especially important to prevent new cases of metabolic diseases, NCDs in digestive system, mental and behavioral disorders, and cancer.

Objective:To explore the application of medical dialectics combined with problem-oriented teaching based on textbooks in hematology internship teaching.Methods:A total of 100 undergraduate students who practiced in the Department of Hematology of the First Hospital of Jilin University from 2022 to 2023 were selected as the research subjects. Students were randomly assigned to a control group and an observation group, with 50 students in each group. The control group received traditional teaching, while the observation group received medical dialectics combined with textbook-based problem-oriented teaching. We assessed the theoretical and operational scores, classroom performance, comprehensive abilities, and teaching satisfaction of two groups of students using t-test and χ 2 test in SPSS 22.0. Results:The theoretical and operational scores of the observation group were (94.26±5.35) points and (92.68±4.72) points, respectively. The theoretical and operational scores of the control group were (86.16±5.42) points and (81.52±5.28) points, respectively. The differences between the two groups were statistically significant ( P<0.001). The recognition rates were significantly higher by students in the observation group than in the control group ( P<0.05) in terms of improving learning efficiency, self-learning ability, understanding and comprehensive analysis of diseases, problem-solving ability, language and organizational expression ability, integration of theory and practice, clinical thinking ability, and independent thinking ability. The satisfaction with teaching was higher in the observation group than in the control group ( P<0.05) in terms of teaching attitudes, teaching methods, teaching arrangements, practicality of teaching content, clear explanation of teaching theories, and outstanding teaching objectives. Conclusions:The medical dialectics combined with textbook-based problem-oriented teaching can improve the assessment scores of medical students, while helping to cultivate their comprehensive abilities and develop good clinical diagnosis and treatment thinking.

Objective To develop a new model for predicting recurrence after liver transplantation for hepatocellular carcinoma (HCC) beyond Milan criteria based on related preoperative and postoperative indicators. Methods A retrospective analysis was performed for the clinical data of the patients with HCC beyond Milan criteria who underwent orthotopic liver transplantation for the first time in Tianjin First Central Hospital from August 2014 to July 2018, and according to the presence or absence of recurrence during follow-up, the patients were divided into recurrence group and no-recurrence group. The t -test or the Mann-Whitney U test was used for comparison of continuous data between groups, and the chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves, and the log-rank test was used for comparison of survival curves. Univariate and multivariate Cox proportional hazards regression analyses were used to identify the risk factors for recurrence-free survival after surgery. A new model was developed for recurrence after liver transplantation in the patients with HCC beyond Milan criteria based on the risk factors identified. The area under the receiver operating characteristic curve (AUC) was used to evaluate predictive performance, and the Hosmer-Lemeshow test was used to assess the goodness of fit of the model. Results A total of 117 patients with HCC beyond Milan criteria were enrolled in this study, with a median follow-up time of 24 (1-74) months. A total of 53 patients (45.3%) experienced recurrence after surgery, among whom 52 (98.1%) had recurrence within 3 years after surgery, with a median time to recurrence of 6 (1-52) months. The Cox proportional hazards regression analysis showed that preoperative serum alpha-fetoprotein (AFP) >769 ng/mL, neutrophil-lymphocyte ratio (NLR) >3.75, and ki67 index >0.25 were independent risk factors for recurrence-free survival after liver transplantation. The model established based on these three risk factors had an AUC of 0.843, with good sensitivity (88.7%) and specificity (70.3%). The optimal cut-off value was selected according to the maximization of Youden index, and then the patients were divided into low-risk group (0-1 point) and high-risk group (1.5-4 points). The log-rank test showed that the low-risk group had significantly higher 3-and 5-year recurrence-free survival rates than the high-risk group (84.1%/72.0% vs 10.9%/10.9%, χ 2 =29.425, P < 0.001). Conclusion Liver transplantation for HCC beyond Milan criteria should be performed with caution, and the predictive model established based on preoperative AFP, NLR, and ki67 index can accurately assess the indication for liver transplantation in such patients.

Objective:To investigate the clinical characteristics and prognosis of acute myeloid leukemia (AML) patients with positive TLS-ERG fusion gene.Methods:The clinical data of 9 AML patients with positive TLS-ERG fusion gene in the First Hospital of Jilin University from June 2013 to August 2020 were retrospectively analyzed, and the relevant literature was reviewed.Results:Among 9 patients with positive TLS-ERG fusion gene, there were 5 males and 4 females, with a median age of 16 years old (6-40 years old). Five patients received chemotherapy alone, 3 patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT), and 1 patient did not receive systematic treatment. Among 8 patients with systematic treatment, 1 patient had complete remission after the first induction chemotherapy and 5 patients had complete remission after induction therapy. The median overall survival time of 5 patients with chemotherapy alone was 1.5 months (1-11 months), of which 3 patients did not respond to the first course of treatment and died of infection, and 2 patients died after relapse. The median overall survival time of 3 patients with allo-HSCT was 16 months (13-17 months), of which 2 patients died after relapse and 1 patient had sustained molecular complete remission by the end of follow-up.Conclusions:AML with positive TLS-ERG fusion gene has low incidence rate and poor induction efficacy. Hematopoietic stem cell transplantation may partially improve the survival prognosis of patients, but it cannot overcome the adverse effect of positive TLS-ERG fusion gene on prognosis.

  Objective  To study the demographic and clinical characteristics, correlation of genotype and phenotype and treatment of Blau syndrome to facilitate early diagnosis and timely treatment of Blau syndrome.  Methods  Seventy-two patients with Blau syndrome from 11 centers from May 2006 to April 2022 were retrospectively analyzed, and their general information, clinical data, laboratory examination and treatment medication were collected.  Results  The distribution of patients with Blau syndrome was uniform in geographical north and south of China, and there was no obvious gender bias. The mean age of onset was (14.30±12.81) months, and the age of diagnosis was (55.18±36.22) months. 35% of patients with Blau syndrome happened before 1 year old, and all patients developed before 5 years old. 87.50% (63/72) had granulomatous arthritis, 65.28% (47/72) had rash, 36.11% (26/72) had ocular involvement, 27.78% (20/72) had fever, and 15.28% (11/72) had pulmonary involvement. Arthritic manifestations of Blau syndrome were most at risk, followed by rash, ocular involvement, and fever.The first 25 months of the disease, the risk of developing a rash was the greatest. The risk of developing arthritis was the greatest between 25 months and 84 months. The main mutations were p.R334Q and p.R334W, and patients with p.R334Q mutation had relatively high incidence of fever (35.71%[5/14] vs. 14.29%[1/7], P=0.43) and ocular involvement (42.86%[6/14]vs. 28.57%[2/7], P=0.51). There was a relatively high incidence of rash (85.71%[6/7] vs. 64.29%[9/14], P=0.59) in patients with the p.R334W mutation. Forty-five patients(62.50%)were treated with a combina-tion of glucocorticoid and methotrexate. Twenty-two patients were treated with tumor necrosis factor antagonist in addition to glucocorticoid and methotrexate.  Conclusions  The risk of different clinical manifestations of Blau syndrome from high to low was arthritis, followed by rash, ocular involvement and fever. The main treatment was glucocorticoid combined with methotrexate, to which biological agents could be added.

OBJECTIVE: To explore the genetic etiology of a neonate with suggestive features of Cornelia de Lange Syndrome (CdLS). METHODS: Chromosome karyotyping, copy number variation sequencing (CNV-seq) and whole exome sequencing (WES) were carried out for the child. Meanwhile, peripheral venous blood samples were taken from his parents for verifying the suspected pathogenic variants detected in the child. RESULTS: The child has exhibited developmental delay, microcephaly, ptosis, micrognathia, and low ear setting, and was suspected as CdLS. No abnormality was found by karyotyping and CNV-seq analysis. WES has detected 5 heterogeneous variants and 1 hemizygous variant on the X chromosome. Combining the genetic pattern and result of family verification, a hemizygous C.3500T>C (p.ile1167thr) of the SMC1A gene was predicted to underlay the clinical manifestations of the patient. This variant was not recorded in the dbSNP and gnomAD database. PolyPhen2, Provean, SIFT all predicted the variant to be harmful, and PhastCons conservative prediction is was a conservative mutation. ACMG variant classification standard evidence supports are PM2, PP2, and PP3. CONCLUSION The novel c.3500T>C (p.Ile1167Thr) missense mutation of the SMC1A gene probably underlay the genetic etiology of CdLS in this child. Above results has enriched the mutation spectrum of CdLS type II, and facilitated clinical counseling for this family.

Objective To explore the efficacy and prognostic factors of chemotherapy regimens including decitabine in treatment of elderly patients newly diagnosed with acute myeloid leukemia (AML). Methods The clinical data of 47 elderly patients newly diagnosed with AML (except M3) who received chemotherapy regimens including decitabine in the First Hospital of Jilin University from February 2013 to November 2017 were retrospectively analyzed, including 11 patients treated with single decitabine and 36 patients treated with decitabine combined with low_dose chemotherapy group. The treatment outcome and the impact of different factors on the prognosis were also analyzed. Results Of 47 patients, there were 15 males and 32 females, and the median age was 65 years old (60-83 years old). The overall response rate of decitabine plus low_dose chemotherapy group for 1 course was higher than that of single decitabine group [80.6% (26/36) vs. 27.3% (3/11), χ 2 ＝ 8.693, P＝ 0.003], and the former showed less courses to acquire remission than the latter (u＝ 3.133, P＝ 0.002); however, there was no significant difference in the median overall survival (OS) time between the two groups (14 months vs. 12 months, P＝ 0.950). Univariate analysis indicated that the median OS time in the complete remission (CR) group was longer than that in the non_CR group (17 months vs. 5 months, P <0.01). The median OS time of the elderly patients with primary AML was longer than that of the patients with secondary AML (16 months vs. 6 months, P＝ 0.01). Cox multifactor analysis showed that failing to achieve CR was identified as an independent adverse influencing factor ( HR＝0.180, 95% CI 0.085-0.382, P< 0.01). The incidence of neutropenia with fever in the patients treated with decitabine plus low_dose chemotherapy group was higher than that in single decitabine group [69.4% (25/36) vs. 36.4% (4/11), χ2＝3.902, P＝0.048]. Conclusion For newly elderly AML patients, chemotherapy regimens including decitabine are safe and effective.

To explore the influence for combination of nourishing yin and tonifying yang sequential therapy (NYTYST) with Western medicine in treating anovulatory infertility rats with diminished ovarian reserve (DOR) based on TGF-β1/Smads signaling pathway. 
 Methods: A total of 40 female rats were randomly divided into 5 groups, a normal control group, a model group, a Western medicine group, a NYTYST group and a combination group (n=8 in each group). The DOR model was established through orally taking tripterygium pill for continuous 2 weeks. The normal control group and the model group were treated with saline for 10 days. The Western medicine group was treated with hormone replacement therapy (HRT) and ovarian stimulation. The NYTYST group was treated with nourishing yin herbs in proestrus and tonifying yang herbs in late estrus and the combination group was treated with Chinese herb and Western drugs for 10 days. HE staining was used to observe histopathologic changes in ovary. Expression levels of transforming growth factor β1 receptor (TGF-β1R) in rats ovarian were detected by immunohistochemistry. Expression levels of Smad2, Smad3 and Smad7 protein in rat ovarian were detected by Western blot.
 Results: Compared with the control group, the numbers of developing follicles, mature follicles and corpus luteum were decreased , while atrefic follicles were increased significantly in the model group (P<0.01); the levels of TGF-β1R, Smad2 and Smad3 were decreased significantly, while Smad7 was increased significantly (P<0.01). Compared with the model group, the numbers of developing follicles, mature follicles and corpus luteum, Smad2 and Smad3 expression were increased, while atrefic follicles and Smad7 were decreased significantly in the treatment group (P<0.05 or P<0.01). The numbers of developing follicles and corpus luteum in the combination group was superior to the Western medicine group (P<0.05). Compared with the Western medicine group, the levels of TGF-β1R, Smad2 and Smad3 were increased significantly, while Smad7 was decreased significantly in the combination group (P<0.05 or P<0.01). 
 Conclusion: NYTYST combined with Western medicine can improve the function of ovaries reserve by up-regulation of TGF-β1R, Smad2 and Smad3 while down-regulation of Smad7 in DOR rats.
