Objective :
To investigate the antidepressant effects and the underlying mechanisms of tetrahydrocurcumin(THC) and its nanoparticle formulation(THCN).
Methods :
Forty-six male ICR mice were randomly divided into Con group, LPS group, THC group, THCN group and SER group. A mouse depression model was established by intraperitoneal administration of LPS. The anxiety and depression-like behaviors of mice were evaluated by open field test(OFT) and forced swimming test(FST). Myelin staining was applied to assess the extent of demyelination in the prefrontal cortex of the mice. The prefrontal cortex and hippocampus were further examined for the expression levels of glial fibrillary acidic protein(GFAP) and Toll-like receptor 4(TLR4) through quantitative immunofluorescence assays.
Results :
Compared with the Con group, the LPS group showed increased anxiety-like and depressive-like behaviors in both the long-term and short-term experiments(P<0.05); the degree of demyelination increased in the LPS group of the long-term experiment(P<0.01); the expression of GFAP was reduced in the LPS group of the short-term experiment(P<0.01), while the expression of TLR4 increased(P<0.05); the expression of TLR4 decreased in the THC group(P<0.01); the expression of GFAP in the prefrontal cortex of the THCN group was reduced(P<0.01), while the expression of TLR4 increased(P<0.05). Compared with the LPS group, the THC group showed reduced depressive-like behaviors in the long-term experiment(P<0.05), while the anxiety-like and depressive-like behaviors of the THCN group and the SER group were reduced(P<0.05), and the anxiety-like and depressive-like behaviors of the THC group and the THCN group were reduced in the short-term experiment(P<0.05); the degree of demyelination was reduced in the THC group, THCN group and SER group in the long-term experiment(P<0.05); the expression of GFAP increased in the THC group of the short-term experiment(P<0.05), while the expression of TLR4 was reduced(P<0.05), and the expression of GFAP increased in the THCN group(P<0.05). Compared with the THC group, the THCN group and the SER group showed reduced anxiety-like behaviors in the long-term experiment(P<0.05); the expression of GFAP in the prefrontal cortex of the THCN group was reduced in the short-term experiment(P<0.05), while the expression of TLR4 in the hippocampal DG area increased in the short-term experiment(P<0.01).
Conclusion
Tetrahydrocurcumin and its nanoparticle formulation both exert significant ameliorative effects on depression-like behaviors and demyelination in mice induced by lipopolysaccharide. The antidepressant mechanism of THC appears to be mediated through the down-regulation of TLR4 and the up-regulation of GFAP. The mechanism underlying the antidepressant action of THCN seems predominantly focused on the enhancement of GFAP expression.

Objective To analyze the prognosis and influencing factors in patients with radioiodine-refractory differentiated thyroid cancer (RAIR-DTC). Methods A retrospective analysis was conducted on 52 patients with RAIR-DTC who underwent ineffective 131I therapy at the Department of Nuclear Medicine, Cancer Hospital, Chinese Academy of Medical Sciences from October 2016 to January 2020. Patients were categorized into progression and stable groups based on disease progression within five years post-treatment. Differences between groups were analyzed using chi-square test and logistic regression. Independent prognostic risk factors were identified using a Cox proportional hazards model. The Kaplan-Meier method with log-rank test was used to evaluate the impact of treatment on the prognosis of the progression group. Results The 3-year and 5-year survival rates of the 52 patients with RAIR-DTC were 88.5% and 73.1%, respectively. In the progression group, the rates were 81.8% and 57.6%. In the stable group, the rates were 100% and 100%. There were significant differences between the two groups in terms of age, presence of extrathyroidal extension, and the initial 131I treatment dose (P < 0.05). Univariate analysis indicated that the age, pre-ablation stimulated thyroglobulin level before the first 131I treatment, the neutrophil-to-lymphocyte ratio before the first treatment, and the sites of recurrence and metastasis were significantly associated with overall survival (P < 0.05). Multivariate analysis showed that age > 55 years (HR=12.40, 95% CI= 2.09-73.57, P=0.001) and distant metastasis (HR=24.47, 95% CI=4.17-143.75, P < 0.001) were independent risk factors for poor prognosis. Kaplan-Meier curve analysis showed that local surgery and/or targeted therapy significantly prolonged progression-free survival in the progression group (P < 0.001). Conclusion The prognosis for RAIR-DTC is poor, with advanced age and distant metastasis significantly associated with unfavorable outcomes. In elderly patients and those with extrathyroidal invasion, the treatment dose during initial 131I therapy may be appropriately increased to delay disease progression. For patients with disease progression, prompt local surgical intervention and/or targeted therapy is recommended.

ObjectiveTo explore the impact of e-sports activities on adolescents' health based on International Classification of Functioning, Disability and Health (ICF), and conduct a systematic review of health condition and functioning, interventions and outcomes. MethodsThe ICF was used to systematically analyze the physical and mental health and functional impact of adolescents engaging in e-sports activities. Using the keywords and subject heading search method, articles about e-sports, health condition, functioning, functional rehabilitation (intervention) and outcome were searched in CNKI, VIP, Wanfang Database, PubMed, Web of Science and EBSCO from establishment to February, 2022. Systematic review had been adopted for literatures scanning, selection, quality review, and literature synthesis. ICF framework and WHO-FICs coding system were used to analyze the literatures in the fields of e-sport participants' main health condition and health-related conditions, functioning, interventions, and outcomes (health conditions and functioning). Results and ConclusionEight literatures from six countries had been finally included, mainly in the fields of clinical medicine, rehabilitation sciences, sports psychology and rehabilitation psychology. The literatures published mainly after 2015. The average scores on Physiotherapy Evidence Database (PEDro) were 6.88. Using ICF framework, adolescent e-sport participants had main health conditions and functioning at the levels of body, activity and participation, and environment. At body level, the health conditions and functioning involved in the fields of mental function, sensory function and pain, neuromusculoskeletal and motor-related functions, mainly manifested impairments or disorders such as cognitive impairment, emotional disturbance, fatigue, sleep disturbance, depression and anxiety, obesity and musculoskeletal pain. At the individual level, main health conditions and functioning included healthy behaviors (such as sedentary behaviors, insufficient physical activity), diet and malnutrition, and other healthy behaviors. At the level of environment, main factors included support and personal relation, attitudes, services, institutional and policy performance. There were two categories of interventions: interventions at body level, such as physical intervention, psychological intervention; and intervention at activity and participation level, such as social intervention, cognitive-behaviors intervention, social media and moderate-to-high-intensity physical activity. Adolescent participants can get health benefits from interventions in the six dimensions of WHODAS2.0 of cognition, mobility, self-care, getting along with others, life activities, participation and health impact, and specifically manifested improvement in the fields of emotional and cognitive conditions, daily physical activity level, rapidly increasing from light to moderate physical activity; interruption sedentary, increasing in physical activity; enhancement of social relations, accessing to social support; and forming healthy living habits and improving the quality of life and well-being.

ObjectiveTo review the effects of video game intervention on adults motor functioning based on International Classification of Diseases, Eleventh Revision (ICD-11) and International Classification of Functioning, Disability and Health (ICF). MethodsThe literatures about video game therapy and motor dysfunction were retrieved from databases of CNKI, PubMed, Web of Science, and EBSCO, from establishment to June, 2022. The contents of the literatures were analyzed and encoded based on the conceptual framework and coding of ICD-11 and ICF. ResultsSeven articles were included, which were from six countries, involving 59 randomized controlled trials and 2 648 participants, aged 19.8 to 75.4 years, mainly from the fields of medicine, rehabilitation science, video games, exercise interventions and sports science, with publication dates mainly from 2015 to 2021. The intervention types were mainly classified as simple video game, and combination of video game and exercise intervention. The ways of intervention were human-computer interaction, perceptual motor and augmented reality. The intervention scenes were in scene and presentation scene, while the former involved a rehabilitation institution and family environment, and the latter involved a virtual scene and a physical scene. The frequency of interventions was mainly one to five times a week, 20 to 60 minutes a time, for four to 24 weeks. The outcomes of the intervention mainly involved the promoting the recovery of function of joint and bone, improving the static and dynamic balance of gait, increasing muscle strength, improving self-efficacy, reducing anxiety; improving posture control, providing feedback on daily activities; promoting social interaction, increasing social interaction and communication behavior, etc. ConclusionThere are two types of video game interventions: video game alone and video game combined with motor intervention. The video game intervention combines video game and motor intervention through the interaction of virtual sceneries, dynamic activity demonstration and the presentation and feedback of activity goals, to enhance the effectiveness and efficiency of the intervention and improves patients' interest in motor learning. The intervention can be divided into human-computer interaction, perceptual motor and augmented reality. The outcomes of the intervention can be reflected in three aspects: improvement of physical function, promotion of activity and participation, and enhancement of overall function and quality of life.

Objective:To investigate the application of sentinel lymph node biopsy (SLNB) in early-staged cervical cancer by laparoscopy.Methods:It was a prospective, single-arm, single-center clinical study. Seventy-eight cases of cervical cancer patients were collected from July 2015 to December 2018 at the Fourth Hospital of Hebei Medical University. All the patients were injected with tracer into the disease-free block of cervical tissue after anesthesia by the same surgeon who learned sentinel lymph node (SLN) mapping technique in Memorial Sloan-Kettering Cancer Center, and underwent SLN mapping followed by complete pelvic lymphadenectomy. Moreover, all the dissected lymph nodes were stained with hematoxylin eosin staining (HE) pathological examination. Besides, the negative SLN on hematoxylin-eosin staining were detected by immunohistochemistry cytokeratin staining micro-metastasis. To analyze the distribution, detection rate, false negative rate the sensitivity and negative predictive value of the SLN in early-staged cervical cancer by laparoscopy, and explore the value of SLN mapping in predicting the lymph nodes metastasis in early-staged cervical cancer.Results:The overall detection rate of SLN in cervical cancer was 99% (77/78), bilateral detection rate was 87% (68/78). The average of 12.4 lymph node (LN) and 3.6 SLN were dissected for each patients each side. SLN of cervical cancer were mainly distributed in the obturator space (61.5%, 343/558), followed by external iliac (23.5%, 131/558), common iliac (7.3%, 41/558), para-uterine (3.8%, 21/558), internal iliac (2.2%, 12/558), para abdominal aorta (1.1%, 6/558), and anterior sacral lymphatic drainage area (0.7%, 4/558). Fourteen cases of LN metastasis were found among all 78 cases. There were a total of 38 positive LN, including 26 SLN metastasis and 12 none sentinel LN metastasis. Through immunohistochemical staining and pathological ultra-staging, 1 SLN was found to be isolated tumor cells (ITC), and 5 SLNs were found to be micro-metastases (MIC), accounting for 23% (6/26) of positive SLN. SLN mapping with pathological ultra-staging improved the prediction of LN metastasis in cervical cancer (2/14). Metastatic SLN mainly distributed in the obturator space (65%, 17/26), peri-uterine region (12%, 3/26), common iliac region (15%, 4/26), and external iliac region (8%, 2/26). The consistency of the diagnosis of lymph node metastasis by SLN biopsy and postoperative retroperitoneal lymph node metastasis showed that the Kappa value was 1.000 ( P<0.001), indicated that the metastasis status of SLN and retroperitoneal lymph node were completely consistent. The sensitivity, specificity, accuracy, false-negative rate, and negative predictive value of SLN biopsy in the diagnosis of lymph node metastasis were 100%, 100%, 100%, 0, and 100%, respectively. Conclusions:SLN in early-staged cervical cancer patients were mainly distributed in the obturator and external iliac space, pathalogical ultra-staging of SLN could improve the prediction of LN metastasis. Intraoperative SLN mapping is safe, feasible and could predict the state of retroperitoneal LN metastasis in early-staged cervical cancer. SLNB may replace systemic pelvic lymphadenectomy.

Objective:To compare the genotypes and phenotypes between the monozygotic twins via whole genome sequencing to further clarify the autosomal dominant inherited neurofibromatosis type 1 (NF1) variants related to congenital pseudarthrosis (CP).Methods:According to the diagnostic criteria of congenital tibial pseudarthrosis and the clinical diagnostic criteria of NF1, two pairs of monozygotic twins with NF1 were included. Both were female and only one of each pair had congenital pseudarthrosis. The other did not have congenital pseudarthrosis. Whole genome sequencing was performed using the peripheral blood of the two pairs of monozygotic twins. Customized bioinformatics analysis was then performed to identify single nucleotide variants (SNVs), short insertion deletion variants (InDel), copy number variants (CNVs), and structural variants (SVs). Classified the variants according to the American College of Medical Genetics and Genomics (ACMG) and ClinGen criteria. The germline variants within the monozygotic twins were compared to identify the CP patients' unique variants. The shared pathogenic or likely pathogenic germline variants between the unique variants in the CP patients from the twins were also analyzed. Further, the identified disease-causing variants were validated by Sanger sequencing in the family of the twins and their parents. Finally, the genotypes and phenotypes regarding the pathogenic variants of the NF1 gene among the twins were characterized. Results:Both the two monozygotic twins were identified pathogenic variants in the NF1 gene. One with c.3047_3048del (p.Cys1016SerfsTer4), and the other with c.4267A>G (p.Lys1423Glu). By Sanger sequencing validation in family quads, the two CP patients and their siblings harbored de novo heterozygous variants of the NF1 gene. In addition to the NF1 gene, no other genes were identified pathogenic or likely pathogenic variants uniquely in the CP patients compared with their twin sisters, as well as SVs and CNVs. In addition, by analyzing the rare and damaging variants in the two CP patients from the two twins, they had no overlapping genes against the SNVs, InDels, SVs, or CNVs. Conclusion:Whole genome sequencing revealed that both the two monozygotic twins with NF1 were detected pathogenic variants of gene NF1. No other pathogenic variants specific to the CP patients among the twins were identified. The two CP patients shared no other common genes from the detected likely pathogenic variants.

Objective To explore the correlations of lung resistance protein (LRP) and glutathione S transferase π (GST-π) to chemotherapy resistance and prognosis of epithelial ovarian cancer.Methods The expressions of LRP and GST-π in epithelial ovarian cancer were examined with immunohistochemistry.Correlations of LRP and GST-π to chemotherapy efficacy and survival time after operation were analyzed.Results The short-term efficacy rates of ovarian cancer were lower in patients with positive expressions of LRP and GST-π than those with negative expressions [61.2%,61.7% vs 94.1%,89.5%,x2 =6.47,4.94,P =0.011,P =0.026].The positive rates of LRP and GST-π were significant higher in patients with chemotherapy resistance than in those sensitive to chemotherapy [91.3%,87.0% vs 65.1%,62.8%,P < 0.05].Log-rank test showed that patients with positive LRP and GST-π had shorter survival time than those negative,and patients with both positive LRP and GST-π had shorter survival time than those both negative (P < 0.05).Conclusions The expressions of LRP and GST-π in epithelial ovarian cancer could be used to predict chemotherapy resistance and prognosis of patients.
9.Risk factors for portal vein thrombosis following splenectomy in patients with liver cirrhosis
Journal of Clinical Hepatology 2015;31(7):1173-1175
Portal vein thrombosis (PVT) develops in some patients with liver cirrhosis and may aggravate portal hypertension. The risk factors for PVT have not yet been completely clarified. Splenectomy might increase the risk of developing PVT, which may progress to a life-threatening complication after splenectomy if not diagnosed promptly and treated properly. In this review, we discuss the recent findings concerning the risk factors for PVT after splenectomy. It is pointed out that splenectomy is the major cause of PVT developed in patients with liver cirrhosis.
