ABSTRACT
Objective@#To understand the status of anemia among rural children aged 3-6 in central China and its relationship with dietary behavior, and to provide reference for prevention and intervention of anemia in rural children.@*Methods@#From April to June 2021, stratified cluster sampling was used to select 1 246 preschool children aged 3 to 6 years old in rural areas in central China. Peripheral blood of the ring finger was collected. Dietary behaviors regarding consumption of cereals and potatoes, fruits, vegetables, soy products, milk, animal foods, food diversity, and drinking water were investigated. Logistic regression analysis was used to analyze the association between anemia and dietary behaviors.@*Results@#The detection rate of anemia in rural children aged 3-6 in central China was 13.88%. The anemia detection rate of left behind children (19.00%) was higher than that of non left behind children (11.27%), and the difference was statistically significant ( χ 2=13.93, P <0.01). Logistic regression analysis showed that the proportion of left behind children ( OR=1.28, 95%CI =1.16-1.56) with anemia was higher than that of non left behind children ( P <0.01). Consumption of animal food intake ≥3 times/week ( OR=0.82, 95%CI =0.69-0.91), and ≥2 kinds of vegetables ( OR= 0.86, 95%CI =0.71-0.93) were associated with lower rate of anemia ( P <0.05).@*Conclusion@#The detection rate of anemia in rural children aged 3-6 years in central China is relatively high, especially in left behind children. Dietary literacy of caregivers should be further improved regarding increased intake of animal foods and vegetables to reduce the risk for anemia in preschoolers.
ABSTRACT
Inflammation, abnormal cholesterol metabolism, and macrophage infiltration are involved in the destruction of the extracellular matrix of the nucleus pulposus (NP), culminating in intervertebral disc degeneration (IDD). Whether nimbolide (Nim), a natural extract, can alleviate IDD is unclear. In this study, we demonstrated that Nim promotes cholesterol efflux and inhibits the activation of the nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways by activating sirtuin 1 (SIRT1) in nucleus pulposus cells (NPCs) during inflammation. Thus, Nim balanced matrix anabolism and catabolism of NPCs. However, the inhibition of SIRT1 significantly attenuated the effects of Nim. We also found that Nim promoted the expression of SIRT1 in RAW 264.7, which enhanced the proportion of M2 macrophages by facilitating cholesterol homeostasis reprogramming and impeded M1-like macrophages polarization by blocking the activation of inflammatory signaling. Based on these results, Nim can improve the microenvironment and facilitate matrix metabolism equilibrium in NPCs. Furthermore, in vivo treatment with Nim delayed IDD progression by boosting SIRT1 expression, modulating macrophage polarization and preserving the extracellular matrix. In conclusion, Nim may represent a novel therapeutic strategy for treating IDD.

ABSTRACT
BACKGROUND@#Total knee arthroplasty (TKA) can reduce severe joint pain and improve functional disability in hemophilia. However, the long-term outcomes have rarely been reported in China. Therefore, this study aimed to evaluate the long-term outcomes and complications of TKA in Chinese patients with hemophilic arthropathy.@*METHODS@#We retrospectively reviewed patients with hemophilia who underwent TKA between 2003 and 2020, with at least 10 years of follow-up. The clinical results, patellar scores, patients' overall satisfaction ratings, and radiological findings were evaluated. Revision surgery for implants during the follow-up period was recorded.@*RESULTS@#Twenty-six patients with 36 TKAs were successfully followed up for an average of 12.4 years. Their Hospital for Special Surgery Knee Score improved from an average of 45.8 to 85.9. The average flexion contracture statistically significantly decreased from 18.1° to 4.2°. The range of motion (ROM) improved from 60.6° to 84.8°. All the patients accepted patelloplasty, and the patients' patellar score improved from 7.8 preoperatively to 24.9 at the last follow-up. There was no statistically significant difference in clinical outcomes between the unilateral and bilateral procedures, except for a better ROM at follow-up in the unilateral group. Mild and enduring anterior knee pain was reported in seven knees (19%). The annual bleeding event was 2.7 times/year at the last follow-up. A total of 25 patients with 35 TKAs were satisfied with the procedure (97%). Revision surgery was performed in seven knees, with 10- and 15-year prosthesis survival rates of 85.8% and 75.7%, respectively.@*CONCLUSIONS@#TKA is an effective procedure for patients with end-stage hemophilic arthropathy, which relieves pain, improves knee functions, decreases flexion contracture, and provides a high rate of satisfaction after more than ten years of follow-up.

Radiotherapy is one of the important methods for the treatment of pancreatic cancer, and rapid progress has been made in related concepts and technical models of radiotherapy in recent years. With reference to the latest advances in radiotherapy technology and the change of radiotherapy dose mode, which the experts in the field of radiotherapy are concerned with, this article reviews and analyzes recent articles and points out that multimodal images play an important role in guiding radiotherapy for pancreatic cancer, and the dose mode of radiotherapy develops to high-dose hypofractionated radiotherapy. The effect of neoadjuvant radiotherapy has been further confirmed, and strong chemotherapy with the combination of multiple drugs is the main radiotherapy regimen for pancreatic cancer.
ABSTRACT
The abundance of proteins in human urine is low and easily to be masked by high-abundance proteins during mass spectrometry analysis. Development of efficient and highly selective enrichment methods is therefore a prerequisite for achieving deep coverage of urine protein markers. Notably, different experimental methods would affect the urine protein enrichment efficacy and the coverage of urine proteome. In this study, ultrafiltration, nitrocellulose membrane enrichment and saturated ammonium sulfate precipitation were used to process 10 mL urine samples from five healthy volunteers and five bladder cancer patients. The urine proteins were enriched and separate by SDS-PAGE to compare the purification efficiency of different methods. Moreover, the peptide identification effects of different purification methods were analyzed by mass spectrometry to determine the best method for enriching urine protein histones. Saturated ammonium sulfate precipitation method outperformed the ultrafiltration and the nitrocellulose membrane enrichment methods in terms of the protein enrichment efficacy and quality. The interference of highly abundant albumin was reduced, whereas the amount of low-abundance protein was increased, and the sensitivity of mass spectrometry identification was increased. The saturated ammonium sulfate precipitation method may be applied for large-scale urine processing for screening clinical diagnostic markers through proteomics.

ABSTRACT
SOCS3, a feedback inhibitor of the JAK/STAT signal pathway, negatively regulates axonal regrowth and inflammation in the central nervous system (CNS). Here, we demonstrated a distinct role of SOCS3 in the injured spinal cord of the gecko following tail amputation. Severing the gecko spinal cord did not evoke an inflammatory cascade except for an injury-stimulated elevation of the granulocyte/macrophage colony-stimulating factor (GM-CSF) and interferon gamma (IFN-γ) cytokines. Simultaneously, the expression of SOCS3 was upregulated in microglia, and unexpectedly not in neurons. Enforced expression of SOCS3 was sufficient to suppress the GM-CSF/IFN-γ-driven inflammatory responses through its KIR domain by attenuating the activities of JAK1 and JAK2. SOCS3 was also linked to GM-CSF/IFN-γ-induced cross-tolerance. Transfection of adenovirus overexpressing SOCS3 in the injured cord resulted in a significant decrease of inflammatory cytokines. These results reveal a distinct role of SOCS3 in the regenerating spinal cord, and provide new hints for CNS repair in mammals.
ABSTRACT
Objective@#To explore the risk factors associated with depression in type 2 diabetes mellitus (T2DM) patients with erectile dysfunction (DMED).@*Methods@#A total of 60 male DMED patients in Kangning Hospital Affiliated to Wenzhou Medical University were enrolled.They were divided into group A (DMED with depression, 40 cases) and group B (DMED without depression, 20 cases) according to the results of self-rating depression scale (SDS). The comorbidity rate of DMED and depression was calculated.Baseline index, blood glucose control index, sex hormone index and blood lipid biochemical index were compared between the two groups.Pearson correlation analysis was used to judge the correlation between SDS scale scores and the indicators.Finally, these indicators were substituted into logistic regression analysis to find out the factors that may cause the comorbidity of DMED and depression.@*Results@#The age of the patients in group A was older than that in group B[(55.95±6.33)years vs.(44.15±5.08)years, t=7.242, P=0.000], the course of T2DM in group A was longer than that in group B [(10.28±0.94)years vs.(4.38±0.60)years, t=29.467, P=0.000]. The fast plasma glucose (FPG)[(10.24±1.55)mmol/L vs.(8.22±1.15)mmol/L, t=5.153, P=0.000], fasting insulin (FIns) [(21.34±2.58)mU/L vs.(17.35±2.13)mU/L, t=5.967, P=0.000] and glycosylated hemoglobin (HbAlc) [(8.75±1.05)% vs.(6.55±0.84)%, t=8.146, P=0.000] in group A were higher than those in group B. Testosterone (TT) level in group A was lower than that in group B [(1.89±0.24)ng/mL vs.(2.46±0.31)ng/mL, t=-7.855, P=0.000]. The luteinizing hormone (LH) [(12.95±1.14)U/L vs.(8.53±0.70)U/L, t=18.515, P=0.000] and follicle-stimulating hormone (FSH) [(19.55±1.83)U/L vs.(15.40±1.47)U/L, t=8.808, P=0.000] in group A were higher than those in group B. Pearson analysis showed that the SDS scale score was positively correlated with age, T2DM duration, FPG, Fins, HbAlc, LH, FSH (r=0.310, 0.503, 0.465, 0.583, 0.676, 0.355, 0.540, P=0.002, 0.008, 0.017, 0.022, 0.030, 0.026, 0.011), and negatively correlated with TT level (r=-0.713, P=0.028). Logistic regression analysis showed that the age, the course of T2DM and TT were the independent risk factors which caused the comorbidity of DMED and depression.@*Conclusion@#In male T2DM patients, the independent risk factors for DMED with depression are age, long duration, and low TT level.

ABSTRACT
Objective To investigate the acute adverse reactions of craniospinal irradiation with helical tomotherapy in medulloblastoma patients and its risk factors. Methods A total of 20 patients with medulloblastoma who received craniospinal irradiation with helical tomotherapy between October 2012 and September 2016 in Air Force General Hospital were selected. The acute adverse events of 20 patients during the treatment were record. According to National Cancer Institute Common Terminology Criteria Adverse Events (NCI-CTCAE) version 4.0, the adverse reactions were divided into the mild group (grade 0-Ⅱ) and severe group (grade Ⅲ-Ⅳ) adverse reactions. And the risk factors were also analyzed. Results The non-hematological adverse reactions included fatigue (55％), vomiting (45％) and headache (25％). The hematological adverse reactions included leukopenia (95％), thrombocytopenia (55％) and lower hemoglobin (45％), and the incidence of severe adverse reactions was 35％ (7/20), 20％ (4/20) and 0 ( 0/20 ) , respectively . Leukopenia occurred in 18 patients ( 90％) at the beginning of radiotherapy within 2 weeks, and thrombocytopenia occurred in 8 patients (40％) at the beginning of radiotherapy after 2 weeks. Single factor analysis showed that there were no statistical differences in hematological adverse events of gender, age and radiation dose of spinal cord (all P>0.05). The incidence of leukopenia for the patients who received the chemotherapy before the radiotherapy was higher than that for the patients without the chemotherapy before the radiotherapy (P< 0.05). Conclusions The hematological adverse reactions were the major acute adverse events during the craniospinal irradiation with helical tomotherapy in patients with medulloblastoma. Theincidence of leukopenia and thrombocytopenia is common, and the incidence of hematological adverse reactions is higher after the chemotherapy. Thus, the close monitoring of hemogram change and treatment of hematological adverse reactions in time during the radiotherapy should be taken into the consideration.
ABSTRACT
Objective To introduce the therapeutic procedures of helical tomotherapy based total marrow irradiation(HT-TMI), and validate the feasibility of TMI. Methods At 1 week before bone marrow transplantation,12 patients received TMI conditioning regimen at a prescriptive dose of 12 Gy in 3 times,once daily. Patient immobilization, CT simulation, target delineation, plan design and dosimetric verification were implemented in sequence according to the TMI procedures. The dosimetric paramaters of the target and normal tissues were analysed. The correlation between the dose verification and image-guided results was observed. Results Compared with total body irradiation(TBI), TMI could significantly reduce the irradiation dose to normal tissues. The median dose D50of all normal tissues except the oral cavity were lower than 6 Gy,where The D50of lens,brain,lung and liver are (1.8±0.1) Gy, (5.7±0.2) Gy, (5.2±0.2) Gy, and (4.6±0.2) Gy, respectively. Pass rate of γ Index was larger than 95% with 3mm/3% criterian for each section. The positioning error of head and neck was relatively lower than that of pelvis at x-axis,and was higher at z-axis.Conclusions Helical tomotherapy based TMI is a feasible and reasonable approach,which has evident dosimetric advantage.

The average and neutral position BED10 respectively were 101416 Gy and 102700 Gy,the number of neutral position chemotherapy period was 4. Kaplan-Meier method, survival analysis, Cox model, multi factor Prognosis analysis were used. Results By the end of January 10,2017 in 36 months' neutral position follow-up visit, the total effective rate of lesion treatment of 86%;the survival rates after 1,2 and 3 years respectively were 74%, 70% and 51%. Neutral survival time was 48 months, and the progression-free time of neutral position was 15 months. Multi-factor analysis indicated that,ECOG<2 and ECOG≥2(P=0000),BED10<100 Gy and BED10≥100 Gy ( P=0006) generated obvious influence on survival prognosis. About 90% of the patients only got 1-2 degree of adverse reaction without emerging treatment related death. Conclusions On the premise of systematic therapy of oligometastasis non-small cell lung cancer, combined with radical radiotherapy of primary lesion and metastasis can obviously improve patients ' overall survival and progression-free survival,the adverse reaction is durable.
