Abstract
BACKGROUND Impaired osteo-/angiogenesis, excessive inflammation, and imbalance of the osteoimmune homeostasis are involved in the pathogenesis of the alveolar bone defect caused by periodontitis. Unfortunately, there is still a lack of ideal therapeutic strategies for periodontitis that can regenerate the alveolar bone while remodeling the osteoimmune microenvironment. Quercetin, as a monomeric flavonoid, has multiple pharmacological activities, such as pro-regenerative, anti-inflammatory, and immunomodulatory effects. Despite its vast spectrum of pharmacological activities, quercetin's clinical application is limited due to its poor water solubility and low bioavailability. RESULTS In this study, we fabricated a quercetin-loaded mesoporous bioactive glass (Quercetin/MBG) nano-delivery system with the function of continuously releasing quercetin, which could better promote the bone regeneration and regulate the immune microenvironment in the alveolar bone defect with periodontitis compared to pure MBG treatment. In particular, this nano-delivery system effectively decreased injection frequency of quercetin while yielding favorable therapeutic results. In view of the above excellent therapeutic effects achieved by the sustained release of quercetin, we further investigated its therapeutic mechanisms. Our findings indicated that under the periodontitis microenvironment, the intervention of quercetin could restore the osteo-/angiogenic capacity of periodontal ligament stem cells (PDLSCs), induce immune regulation of macrophages and exert an osteoimmunomodulatory effect. Furthermore, we also found that the above osteoimmunomodulatory effects of quercetin via macrophages could be partially blocked by the overexpression of a key microRNA--miR-21a-5p, which worked through inhibiting the expression of PDCD4 and activating the NF-κB signaling pathway. CONCLUSION In summary, our study shows that quercetin-loaded mesoporous nano-delivery system has the potential to be a therapeutic approach for reconstructing alveolar bone defects in periodontitis. Furthermore, it also offers a new perspective for treating alveolar bone defects in periodontitis by inhibiting the expression of miR-21a-5p in macrophages and thereby creating a favorable osteoimmune microenvironment.

Abstract
Objectives: To assess the efficacy of cord blood-assisted haploid peripheral blood stem cell transplantation (haplo-cord-PBSCT) versus unrelated donor peripheral blood stem cell transplantation (UD-PBSCT) in the treatment of malignant hematological diseases. Methods: A retrospective analysis was performed on one hundred and four patients with malignant hematological diseases who underwent haplo-cord-PBSCT and fifty-two patients who underwent UD-PBSCT at Xiangya Hospital of Central South University between January 2016 and December 2021. Results: ①The median implantation time for neutrophils in the haplo-cord-PBSCT and UD-PBSCT groups was 13 (9-22) days and 13 (10-24) days, respectively (P=0.834), whereas the median implantation time for platelets was 15 (7-103) days and 14 (8-38) days, respectively (P=0.816). The cumulative implantation rate of neutrophils at 30 days after transplantation in the haplo-cord-PBSCT group and the UD-PBSCT group was 100% (P=0.314), and the cumulative platelet implantation rate at 100 days after transplantation was 95.2% (95% CI 88.3% - 98.1% ) and 100% (P=0.927), respectively. 30 days after transplantation, both groups of patients achieved complete donor chimerism, and no umbilical cord blood stem cells were implanted. ②The cumulative incidence rates of grade Ⅱ-Ⅳ acute GVHD within 100 days after transplantation in the haplo-cord-PBSCT group and the UD-PBSCT group were 29.1% (95% CI 20.1% -38.1% ) and 28.8% (95% CI 17.2% -41.6% (P=0.965), respectively. The cumulative incidence rates of grade Ⅲ/Ⅳ acute GVHD were 7.8% (95% CI 3.6% -14.0% ) and 9.6% (95% CI 3.5% -19.5% ) (P=0.725). The cumulative incidence rates of 2-year chronic GVHD in the haplo-cord-PBSCT group and the UD-PBSCT group were 45.3% (95% CI 36.1% -56.1% ) and 35.1% (95% CI 21.6% -44.1% ), respectively (P=0.237). The cumulative incidence rates of severe chronic GVHD at 2 years after transplantation were 13.6% (95% CI 7.6% -21.3% ) and 12.9% (95% CI 5.1% -24.3% ), respectively (P=0.840). ③The 2-year CIR after transplantation in the haplo-cord-PBSCT group and UD-PBSCT group were 12.8% (95% CI 7.0% -20.5% ) and 10.0% (95% CI 3.6% -20.2% ), respectively (P=0.341), and the NRM were 14.7% (95% CI 8.4% -22.6% ) and 16.2% (95% CI 7.4% -28.0% ), respectively (P=0.681). ④The 2-year OS rates in the haplo-cord-PBSCT and UD-PBSCT groups after transplantation were 82.2% (95% CI 74.8% -90.3% ) and 75.5% (95% CI 64.2% -88.7% ), respectively (P=0.276). The 2-year DFS rates were 69.9% (95% CI 61.2% -79.8% ) and 73.8% (95% CI 62.4% -87.3% ), respectively (P=0.551). The 2-year rates of GVHD-free/recurrence-free survival (GRFS) were 55.3% (95% CI 44.8% -64.8% ) and 64.7% (95% CI 52.8% -79.3% ), respectively (P=0.284) . Conclusion: The findings of this study indicate that haplo-cord-PBSCT and UD-PBSCT have comparable efficacy and safety in the treatment of malignant hematological diseases and can be used as an alternative treatment options.

Abstract
BACKGROUND Coordination between osteo-/angiogenesis and the osteoimmune microenvironment is essential for effective bone repair with biomaterials. As a highly personalized and precise biomaterial suitable for repairing complex bone defects in clinical practice, it is essential to endow 3D-printed scaffold the above key capabilities. RESULTS Herein, by introducing xonotlite nanofiber (Ca6(Si6O17) (OH)2, CS) into the 3D-printed silk fibroin/gelatin basal scaffold, a novel bone repair system named SGC was fabricated. It was noted that the incorporation of CS could greatly enhance the chemical and mechanical properties of the scaffold to match the needs of bone regeneration. Besides, benefiting from the addition of CS, SGC scaffolds could accelerate osteo-/angiogenic differentiation of bone mesenchymal stem cells (BMSCs) and meanwhile reprogram macrophages to establish a favorable osteoimmune microenvironment. In vivo experiments further demonstrated that SGC scaffolds could efficiently stimulate bone repair and create a regeneration-friendly osteoimmune microenvironment. Mechanistically, we discovered that SGC scaffolds may achieve immune reprogramming in macrophages through a decrease in the expression of Smad6 and Smad7, both of which participate in the transforming growth factor-β (TGF-β) signaling pathway. CONCLUSION Overall, this study demonstrated the clinical potential of the SGC scaffold due to its favorable pro-osteo-/angiogenic and osteoimmunomodulatory properties. In addition, it is a promising strategy to develop novel bone repair biomaterials by taking osteoinduction and osteoimmune microenvironment remodeling functions into account.

Abstract
Objective: To investigate the correlations between cosmetic and radiographic parameters of shoulder balance, as well as the variations in cosmetic shoulder balance observed from different perspectives, among patients with adolescent idiopathic scoliosis (AIS) characterized by thoracic curves. Methods: A total of 43 patients with thoracic curves treated from July to October in 2022 in Nanjing Drum Tower Hospital were recruited in this study. There were 9 males and 34 females with a mean age of (14.3±1.5) years. All participants underwent comprehensive radiographic assessments and were photographed both from posterior and anterior views, focusing on the shoulder region as well as a higher level (maintaining a consistent vertical distance of 180 cm from the ground). Six cosmetic parameters were measured on the photographs: shoulder angle(α1), axilla angle(α2), shoulder area index 1(SAI1), shoulder area index 2 (SAI2), inner shoulder height (SHi) and outer shoulder height (SHo). Eight radiographic parameters were measured on the radiographs: radiographic shoulder height difference (RSHD), first rib angle (FRA), clavicle-rib cage intersection (CRCI), coracoid process height (CPH), T1 tilt, clavicle angle(CA), clavicle chest cage angle difference (CCAD) and Cobb angle. Differences among bilateral cosmetic indicators from different perspectives were analyzed and compared, and their correlation with bilateral radiographic indicators was studied. Results: There was no significant differences between anterior cosmetic parameters and posterior cosmetic parameters at the same level of observation(all P>0.05). However, when observing SHi, SHo, α1, and α2 at the shoulder level, it became evident that they exhibited significantly higher values compared to the corresponding higher level on the same side of the patients' bodies. This contrast was observed in both the dorsal [SHo: (0.11±1.20) cm vs (-0.44±1.39) cm, P=0.005; SHi: (0.64±0.86) cm vs (0.32±0.56) cm, P=0.003; α1:-0.47°±2.27° vs -0.77°±2.49°, P=0.014; α2:-3.06°±3.23° vs -2.21°±3.03°, P=0.034] and ventral [SHo: (0.12±1.29) cm vs (-0.48±1.35) cm, P=0.007; SHi: (0.61±0.88) cm vs (0.30±0.59) cm, P=0.006; α1:-0.46°±2.18° vs -0.69°±2.35°, P=0.018; α2:-3.26°±3.12° vs -2.05°±2.97°, P=0.029] aspects of the patients. SHi and SHo were more sensitive to this difference of height. The correlation coefficients between radiographic parameters and cosmetic aspects at the shoulder level varied from 0.374 to 0.767. Similarly, the correlation coefficients between radiographic parameters and cosmetic factors at the higher level ranged from 0.273 to 0.579 (all P<0.05). Conclusions: The cosmetic parameters had significant difference between different perspective of observation, the cosmetic parameters are needed to be observed at the shoulder level in the evaluation of patients' shoulder balance.

Abstract
Objective: To explore the clinical features and prognosis of children with histiocytic necrotizing lymphadenitis (HNL). Methods: The clinical data of 118 children with HNL diagnosed and treated in the Department of Rheumatology and Immunology of Children's Hospital, Capital Institute of Pediatrics from January 2014 to December 2021 were retrospectively analyzed. The clinical symptoms, laboratory examination, imaging examination, pathological findings, treatment and follow-up were analyzed. Results: Among the 118 patients, 69 were males and 49 were females. The age of onset was 10.0 (8.0, 12.0) years, ranging from 1.5 to 16.0 years. All the children had fever lymph node enlargement, blood system involvement in 74 cases (62.7%), skin injury in 39 cases (33.1%). The main manifestations of laboratory examination were increased erythrocyte sedimentation rate in 90 cases (76.3%), decreased hemoglobin in 58 cases (49.2%), decreased white blood cells in 54 cases (45.8%) and positive antinuclear antibody in 35 cases (29.7%). Ninety-seven cases (82.2%) underwent B-mode ultrasound of lymph nodes, showing nodular lesions with low echo in the neck; 22 cases (18.6%) underwent cervical X-ray and (or) CT; 7 cases (5.9%) underwent cervical magnetic resonance imaging. Lymph node biopsy was performed in all 118 cases, and the pathological results did not support malignant diseases such as lymphoma or Epstein-Barr virus infection, suggesting HNL. Fifty-seven cases (48.3%) recovered without treatment, 61 cases (51.7%) received oral steroid therapy, and 4 cases (3.4%) received indomethacin as anal stopper. The 118 cases were followed up for 4 (2, 6) years, ranging from 1 to 7 years, 87 cases (73.7%) had one onset and did not develop into other rheumatological diseases, and 24 cases (20.3%) had different degrees of recurrence, 7 cases (5.9%) had multiple system injuries, and all of the tested autoantibodies were positive for medium and high titers. All of them developed into other rheumatic immune diseases, among which 5 cases developed into systemic lupus erythematosus and 2 cases developed into Sjogren's syndrome; 7 cases were given oral steroid therapy, including 6 cases plus immunosuppressant and 2 cases receiving methylprednisolone 20 mg/kg shock therapy. Conclusions: The first-onset HNL portion is self-healing, hormone-sensitive and has a good prognosis. For HNL with repeated disease and multiple system injury, antinuclear antibody titer should be monitored during follow-up, and attention should be paid to the possibility of developing into other rheumatological diseases, with poor prognosis.

Abstract
Objective: To evaluate the efficacy and safety of belimumab in children with systemic lupus erythematosus (cSLE). Methods: The clinical data of 49 cSLE patients admitted into the Department of Rheumatology and Immunology, Children's Hospital affiliated to the Capital Institute of Pediatrics, from August 2018 to December 2021 were collected. They were divided into the belimumab treatment group (18 cases) and the traditional treatment group (31 cases) according to whether they received belimumab treatment. The cSLE patients in the traditional group had similar baseline SLEDAI scores with the belimumab group and were treated with traditional immunosuppressive drugs. The clinical symptoms and improvements before and after treatment, as well as the differences in adverse events during follow-up were compared between the two groups. Results: In belimumab group, the age was (11.9±1.8) years old, the median (Q1, Q3) of disease duration was 7.5 (2.0, 16.8) months, 3 patients were male, and 15 patients completed 24 weeks of treatment. In the traditional treatment group, 31 patients with cSLE were enrolled, with an average age of (11.3±2.4) years, a median (Q1, Q3) of disease duration of 7.0 (2.5, 10.5) months, among whom 6 patients were male, and 25 patients completed 24 weeks of treatment. At baseline, the belimumab treatment group had a significantly lower oral prednisone dose than the conventional treatment group [(29.58±12.43) mg/d vs (38.20±14.11) mg/d, P=0.037]. After 24 weeks of treatment, the dosage of prednisone in both groups was reduced, and the dosage of prednisone in the belimumab group was (14.12±5.86) mg/d, which was lower than that in the traditional treatment group [(23.51±9.79) mg/d] (P=0.002). After 24 weeks of treatment, the levels of complement C3 and C4 increased, the dsDNA levels and SLEDAI score decreased in both groups (all P>0.05). The incidence of adverse events in belimumab group (3/15, 3 cases) was lower than that in traditional treatment group (32.0%, 8/25) (P>0.05). Conclusions: Belimumab in the treatment of cSLE can reduce the initial dose of prednisone and facilitate the reduction of prednisone dose, significantly improve the clinical symptoms and organ involvement, and reduce the disease activity. The incidence of adverse events was low during belimumab treatment.

Abstract
This study aims to explore optimized teaching mode of cancer epidemiology for undergraduates, and provide scientific ideas and basis for improving teaching quality. Non-randomized concurrent control study was used. Undergraduates, enrolled in 2018, from the department of preventive medicine in A and B medical universities were selected as research objects. Traditional teaching mode was used for cancer epidemiology course in A medical university, and innovative teaching mode named "one core, four dimensions" was adopted in B medical university. After the course, questionnaire method was used to investigate self-cognition of students, teaching satisfaction and class preparation time of teachers in B Medical University. The post-class test method was used to compare the students' grades of cancer epidemiology in the two universities. The results indicated that among the 58 students of B medical university, 94.83% (55/58) students were familiar with common types of epidemiological studies and 86.21% (50/58) mastered the evaluation indicators of screening research. Among the nine teaching faculties from B medical university, seven reported that the new teaching plan helped students to learn frontier knowledge of cancer epidemiology, and eight reported the new teaching model was conducive to the interaction between teachers and students. The text score of students in B medical university was 50.34±4.90, significantly higher than that in A medical university (46.21±4.91, t=5.20, P<0.001). The optimized teaching mode of cancer epidemiology is highly praised by students and teachers, which has the potential to improve students' grasp of cancer epidemiology, the ability to combine theory with practice, and the teaching effect of cancer epidemiology.

Abstract
Objective: To explore the effect of lead exposure on the neurobehavior and gut microbiota community structure in mice. Methods: In August 2019, 64 C57BL/6 mice were randomly divided into 4 groups: control group (0 ppm) , low lead exposure group (20 mg/l) , medium lead exposure group (100 mg/l) and high lead exposure group (500 mg/l) . During the experiment, they were free to eat and drink. The drinking water of the lead exposure group was mixed with lead acetate, and sodium acetate was added in the control group. After 10 weeks of exposure, the Morris water maze was used to test the learning and memory ability of each group of mice, and then they were sacrificed for sampling. ICP-MS was used to detect lead content in whole blood and brain tissue. ELISA was used to determine the level of IL-1β in mouse serum. 16S rRNA sequencing was used to detect the structural diversity of the intestinal flora in feces, and then the correlation between the flora and behavior indicators was analyzed. Results: In the Morris water maze experiment, compared with the control group, there was no significant difference in the body weight and swimming speed of the mice in the lead exposure groups. The escape latency of the mice in the 100 mg/l and 500 mg/l dose groups was prolonged, and the number of platform crossings decreased (P<0.05) ; meanwhile, the staying time of the mice in the 500 mg/l Pb-treated group in the target quadrant was lower than that of the control group, and the difference was statistically significant (P<0.05) . Compared with the control group, the blood lead content of the mice in each lead exposure group was significantly increased, and the brain lead content of mice in the 500 mg/l dose group was significantly elevated (P<0.05) . The serum IL-1β levels of mice in each lead exposure group were higher than those of the control group (P<0.05) . At the phylum level, the relative abundance of the Proteobacteria phylum in all of Pb-treated groups was significantly increased (P<0.05) ; at the genus level, Allobaculum, Desulfovibrio, Lachnospiraceae_NK4A136_group, Turicibacter and Ureaplasma were significantly increased (P<0.05) . Among them. The relative abundance of Desuffaoibrio, Turici bacter, and Ureaplasma was negatively correlated with the residence time of mice in the quadrant of the platform (r=-0.32, -0.29, -0.44, P<0.05) . Conclusion: Lead exposure induced learning and memory impairments in mice, which may be related to the disturbance of the gut microbiota.

Abstract
Multidrug-resistant (MDR) Staphylococcus aureus and its biofilm formation have been challenging to control in milk and dairy industries. Biofilms formed by Staph. aureus may result in the failure of antibacterial agents and disinfectants to penetrate the biofilm in an attempt to control contamination. Novel natural antibacterial agents are required to combat MDR bacteria and biofilms. In this study, we evaluated the bactericidal, antibiofilm, and antimotility effects of Rumex japonicus Houtt. (RJH) extract on MDR Staph. aureus isolated from milk. The RJH extract exhibited good antibacterial activity against MDR strains with minimum inhibitory concentrations (MIC) ranging from 0.78 to 6.25 mg/mL and minimum bactericidal concentrations ranging from 3.125 to 12.5 mg/mL. The extract showed strong inhibition of biofilm formation (81.9%) at sub-MIC value and eradication of biofilm at higher concentrations. The motility of Staph. aureus was effectively blocked by the extract. Major compounds emodin, chrysophanol, and physcion were identified in RJH extract using HPLC-linear trap quadrupole (LTQ)/Orbitrap-mass spectrometry. The extract was nontoxic to human epithelial cell lines such as Caco-2 and HT-29 cell lines at concentrations ranging from 0.1 to 0.5 mg/mL, and from 0.1 to 0.75 mg/mL, respectively. These findings suggest that RJH extract could be an alternative to synthetic preservatives in milk and dairy products.

Abstract
Objective: To summarize the clinical characteristics of children with rheumatic disease combined with endocrine disorder. Methods: A retrospective analysis was performed on the clinical data, including sex, age, clinical presentation, laboratory tests, treatment and outcome, of 13 patients with rheumatic diseases combined with endocrine disorder, who were admitted to our department in Children's Hospital, Capital Institute of Pediatrics from January 2014 to December 2020. Results: Among the 13 cases, 3 were males and 10 were females, without family history. Their age was (10±4) years. And the average course of disease was 4.1 months. Eight of them were diagnosed with systemic lupus erythematosus (JSLE), 2 with juvenile idiopathic arthritis (JIA), 1 with childhood vasculitis, 1 with juvenile-onset systemic sclerosis (JSSc) and 1 had juvenile dermatomyositis (JDM). Regarding the initial presentation, 10 cases had symptoms of rheumatic disease, 2 had polydipsia and polyuria, and 1 had goiter. All the 13 patients had multiple system involvement. Regarding endocrine disorder, 10 had thyroiditis or subclinical thyroiditis, 4 had diabetes mellitus and one had both thyroid and pancreas involvement. Thyroid stimulating hormone in 10 patient with thyroid involvment was 19.6 (5.2-34.0) mU/L, and their total thyroxine was 75.3 (45.2-105.4) nmol/L. Besides, thyroid peroxidase antibody or thyroglobulin antibody was positive in 7 cases. The blood glucose of 4 children with pancreatic injury was 25.0 (17.0-33.0) mmol/L, and C-peptide was 0.4 (0.3-0.5) mg/L. Glutamate dehydrogenase antibody, protein tyrosine phosphatase antibody and zinc transporter 8 antibody were positive in two cases. After treatement with immunosuppressant or immunoglobulin combined with glucocorticoid or nonsteroidal antiinflammatory drugs for rheumatic symptoms, and levothyroxine or insulin for endocrine diseases, they were all followed up for more than 6 months and maintained clinical stability. Conclusions: Rheumatic diseases in children can be complicated with endocrine disorders, and the involved organs are usually thyroid and pancreas. In children with rheumatic disease, thyroid injury usually has subtle onset, whereas pancreas injury develops rapidly, even life-threatening. Insulin should be used persistently under the instruction of endocrinologist.

Abstract
Objective: To identify the threshold of a health warning system based on the association of apparent temperature and years of life lost (YLL). Methods: Daily mortality records and meteorological data were collected from 364 Chinese counties for 2006-2017. Distributed lag nonlinear model and multivariate Meta-analyses were applied to estimate the association between the apparent temperature and YLL rate. A regression tree model was employed to estimate the warning thresholds of the apparent temperature. Stratified analyses were further conducted by age and cause of death. Results: The daily YLL rate was 23.6/105. The mean daily apparent temperature was 15.7 ℃. U-shaped nonlinear associations were observed between apparent temperature and YLL rate. The actual temperature-caused YLL rate for the elderly was higher than the young population. The daily excess deaths rate increased with the higher effect levels. Conclusions: Regression tree model was employed to define the warning threshold for meteorological health risk. The present study provides theoretical support for the weather-related health warning system.

Abstract
Due to the poor repair ability of cartilage tissue, regenerative medicine still faces great challenges in the repair of large articular cartilage defects. Quercetin is widely applied as a traditional Chinese medicine in tissue regeneration including liver, bone and skin tissues. However, the evidence for its effects and internal mechanisms for cartilage regeneration are limited. In the present study, the effects of quercetin on chondrocyte function were systematically evaluated by CCK8 assay, PCR assay, cartilaginous matrix staining assays, immunofluorescence assay, and western blotting. The results showed that quercetin significantly up-regulated the expression of chondrogenesis genes and stimulated the secretion of GAG (glycosaminoglycan) through activating the ERK, P38 and AKT signalling pathways in a dose-dependent manner. Furthermore, in vivo experiments revealed that quercetin-loaded silk protein scaffolds dramatically stimulated the formation of new cartilage-like tissue with higher histological scores in rat femoral cartilage defects. These data suggest that quercetin can effectively stimulate chondrogenesis in vitro and in vivo, demonstrating the potential application of quercetin in the regeneration of cartilage defects.

Abstract
Objective: To analyze the compliance and related factors of low-dose computed tomography (LDCT) screening among the high-risk population of lung cancer in three provinces participating in the cancer early diagnosis and early treatment program in urban areas of China. Methods: From October 2017 to October 2018, 17 983 people aged between 40 and 74 years old at high risk of lung cancer were recruited from Zhejiang, Anhui and Liaoning provinces. The basic demographic characteristics, living habits, history of the disease and family history of cancer were collected by using a cancer risk assessment questionnaire, and the data of participants examined by LDCT were obtained from the hospitals participating in the program. The screening compliance was quantified by the screening participation rate, and it was calculated as the proportion of participants completing LDCT scan among high-risk population. The related factors of LDCT screening compliance were analyzed by using a multivariate logistic regression model. Results: The age of 17 983 participants was (56.52±8.22) years old. Males accounted for 51.9% (N=9 332), and 69.5% (N=12 495) had ever smoked, including former smokers and current smokers. A total of 6 269 participants were screened by LDCT, and the screening participation rate was 34.86%. The results of multivariate logistic regression analysis showed that the age group of 50 to 69 years old, female, passive smokers, alcohol consumption, family history of lung cancer and history of chronic respiratory diseases were more likely to be screened by LDCT, while the compliance of LDCT screening in current smokers was low. Conclusions: The LDCT screening compliance of the high-risk population of lung cancer in urban areas of China still needs to be improved. Age, sex, smoking, drinking, family history of lung cancer and history of chronic respiratory disease are associated with screening compliance.

Abstract
Objective: To analyze the clinical characteristics of infantile Takayasu arteritis and the efficacy of infliximab (IFX). Methods: Clinical manifestations, laboratory investigations and infliximab intervention of a case with infantile Takayasu arteritis, who was admitted to Department of Rheumatism and Immunology, Children's Hospital, Capital Institute of Pediatrics in January 2018, were reviewed and analyzed. The related literature published from the beginning to March 2020 were retrieved from CNKI, Wanfang, SinoMed and PubMed with the keywords of"Takayasu arteritis","Infant" in both Chinese and English. Results: This case was a 70-day-old boy admitted due to recurrent fever for 20 days. On admission, his blood pressure were 104/90, 95/59, 125/80, and 152/125 mmHg (1 mmHg=0.133 kPa) in the right arm, left arm, right leg, and left leg, respectively. The complete blood cell count showed leukocytosis (22.6×109/L), thrombocytosis (858×109/L) and mild anemia (80 g/L). He also had elevated erythrocyte sedimentation rate (119 mm/1h), serum ferritin (598 μg/L) and C-reactive protein (112 mg/L). Computed tomographic angiography (CTA) showed narrowing of the thoracic and abdominal aorta, with thickening and heterogenous enhancement of the vessel wall. Coronary artery ultrasound detected dilatation and wall thickening of the bilateral coronary arteries, and uneven dilatation of the middle segment of the right coronary artery, showing bead-like change. Vessel wall thickening was also found in the other main arteries, including both femoral arteries, axillary arteries, carotid arteries, and subclavian arteries, and both superficial femoral arteries were slightly narrowed in the distal segments. The diagnosis of TA was confirmed, and the boy was treated with infliximab monotherapy (5 mg/(kg·every time), a total of 13 times). Then his body temperature and all inflammatory markers were normalized, and the vascular pathology was resolved according to the radiography. No side effects such as allergy or infection were noted during the treatment. During the 2 years and 6 months of follow-up, the boy maintained normal growth and development. Literature review found 8 related articles, and one of them was in Chinese but had limited information. In the other 7 papers, a total of 7 infants with TA were reported. The most common symptom was fever (5 cases), and inflammatory markers usually elevated, and the most common affected artery was abdominal aorta (6 cases). Most cases were treated with glucocorticoid. Conclusions: TA is a rare disease in infants, usually presents with fever and increased inflammatory markers. At the early stage, infliximab monotherapy could effectively control the symptoms and ensure normal growth and development.

Abstract
Objective: To investigate the feasibility of circulating tumor DNA (ctDNA) in detecting small cell lung cancer (SCLC) gene mutations and its prognostic value in chemotherapy and/or radiotherapy for SCLC patients. Methods: A total of 77 SCLC patients who were admitted to the Department of Thoracic Medical Oncology and the Department of Thoracic Radiation Oncology of Zhejiang Cancer Hospital from July 2016 to November 2019 were included. There were 66 males and 11 females, with a median age of 60 years. Among them, 42 cases were in limited stage (LS) and 35 cases were in extensive stage (ES). Next-generation sequencing (NGS) of patients' plasma ctDNA was performed before treatment. The differences of mutated genes and signaling pathways between LS and ES patients were analyzed and compared. Blood-based tumor mutation burden (bTMB) was calculated according to detected somatic cell mutations. Patients were divided into the high bTMB and the low bTMB groups according to the optimal threshold calculated by R software. Log-rank tests were used to compare progression-free survival (PFS) between the high bTMB and the low bTMB groups. Results: Among the 77 patients, 76 patients had gene mutations detected in their plasma, and the positive rate of ctDNA test was 98%. Among the 76 patients, the genes with the highest mutation frequency were TP53 (89%), RB1 (70%), LRP1B (34%), CREBBP (21%), MLL3 (21%), MLL2 (16%), NOTCH1 (13%), ROS1 (13%), BRCA2 (12%), and PTPRD (12%). The most common mutated genes in LS patients were TP53 (90%), RB1 (68%), LRP1B (24%), MLL2 (22%), and BRCA2 (17%); the most common mutated genes in ES patients were TP53 (89%), RB1 (71%), LRP1B (46%), CREBBP (31%), and MLL3 (29%). The mutation rates of NOTCH1 and CREBBP genes were significantly higher in ES patients (31.4% and 22.9%) than those in LS patients (11.9% and 4.8%) (both P<0.05). Signaling pathway analysis showed that there were more NOTCH pathway gene variations in ES patients. Among LS patients, patients in the high bTMB group (≥ 6.96 mutations/Mb) had a longer PFS than that in the low bTMB group (<6.96 mutations/Mb) (P=0.033); but no such difference was noted in ES patients. Conclusion: Plasma ctDNA sequencing detected SCLC gene mutation profiles similar to those reported in previous literature, thus ctDNA could be used as a tool to study SCLC genomics; the mutation spectra of ES-SCLC and LS-SCLC were different. bTMB has potential prognostic value in LS-SCLCs treated with chemoradiotherapy.

Abstract
Objective: To establish the nutrition literacy core items for Chinese lactating women. Methods: The framework system and preliminary items of nutrition literacy were established through literature review and experts consultation. E-Delphi method was used to determine the nutrition literacy items. 11 experts in the field of maternal and child nutrition, obstetrics and gynecology, health education and nutrition and diseases were invited to score the importance of each nutrition literacy item via Email. The judgment basis and familiarity of experts towards the items, active coefficient, authority coefficient and harmony coefficient were evaluated and analyzed to generate the final list of nutrition literacy items. Results: The active coefficients of consultation in two rounds were 81.8% (9/11) and 87.5% (8/9). The authority coefficients were (0.86±0.11) and (0.85±0.06). The average scores of importance were (4.03±1.24) and (4.64±0.50)and the harmony coefficients were 0.556 (χ²=163.42, P<0.001) and 0.40 (χ²=64.41, P<0.001). After the second round of consultation, all selected items met the inclusion criteria. We identified the final list of nutrition literacy items consisting of 3 scales (basic knowledge and concept, lifestyles and dietary behaviors, and basic skills), 10 subscales (basic nutrition concept, food and nutrition knowledge, feeding knowledge, lifestyles, dietary behaviors, feeding behaviors, weight management, complementary food production, acquisition, understanding and application of nutrition information, judgement of nutrition information, and nutrition decision making) with 24 items in total. Conclusions: The framework system and core items of nutrition literacy were established for Chinese lactating women based on E-Delphi method. The experts involved in the consultation process presented a performance with good representativeness, enthusiasm and authority. All experts' opinions are coordinated and unified, which could satisfy the demand of developing nutrition literacy core items for target population.

Abstract
Nutrition literacy is an important part of health literacy, as well as an significant factor to enhance the quality of population, improving the nutritional status of residents and preventing nutrition-related diseases. In 2010, China developed an evaluation tool for health literacy and began to monitor residents' health literacy. So far, eight national surveys on health literacy have been completed, providing an important basis for health promotion intervention strategies and related policies. However, in health literacy evaluation system, there is neither evaluation content of nutrition literacy, nor evaluation tools. In order to achieve the goals of "national nutrition plan (2017-2030)"and evaluate the implementation effect, it is urgent to carry out the assessment and monitoring of nutrition literacy. According to the nutritional characteristics of different populaitons, this research organizes national experts in related fields, following the principles of scientificity, conciseness and generality and through the scientific formulation procedures to construct the nutrition literacy assessment tools for different populations. This assessment tool can enhance the pertinence and scientificity of nutrition education and improve nutrition development strategy. The establishment of the nutrition literacy assessment tool is the premise of gradually establishing the nutrition literacy assessment system of the residents, and also lays a solid foundation for further conducting the national nutrition literacy evaluation work.

Abstract
Nutrition literacy is one of essential components of health literacy. A relatively mature health literacy evaluation system has been established in China so far. However, the studies on nutrition literacy evaluation are still limited, especially for specific population, such as children, adolescents, older people, and maternal. The present study introduces the concept of nutrition literacy, and summarizes the evaluation tools of nutrition literacy for both general population and special population (i.e., children, adolescents, older people, and maternal) in China and foreign countries, and their dimension, reliability, validity and applicable scope. This study aim to provide evidence for the development of nutrition literacy evaluation tools for different population according to the current problem of nutrition in China.

Abstract
Hallux valgus is a common foot deformity disease caused by various extrinsic and intrinsic factors, and systemic conditions, but the etiopathogenesis and pathogenesis of this deformity are still unknown. Hallux valgus affects 10-20% of Chinese adults. Although considered highly heritable, the candidate gene is unclear. We conducted the first candidate gene study of hallux valgus to identify the biological mechanism. Between June 2015 and July 2018, the records and radiographs of 80 patients diagnosed with hallux valgus and 80 controls who were treated were analyzed. In order to compare the differences in severity associated with this deformity, the charts of 80 patients were divided into 3 groups from the angle of hallux valgus. Clinical and basic studies were also statistically compared by PCR and data analysis. Patients and controls had significant differences in age and gender, however, there were no significant differences in age and gender among the light, moderate and severe groups. Post-operative groups resulted in significant improvements in all of the measured radiographic parameters compared with pre-operative groups. BsmI seemed to show a specific variation, and may serve as a useful bio-marker for the disease (OR = 5.88, 95% CI 1.54-22.35, P <0.001). In this paper, the article which proved the VDR polymorphisms (BsmI) playing an important role in hallux valgus were studied to understand and manage the hallux valgus more scientifically.

Abstract
Objective: To determine whether 60 Gy is superior to standard 50 Gy for definitive concurrent chemoradiation(CCRT) in esophageal squamous cell carcinoma (ESCC) using modern radiation technology in a phase Ⅲ prospective randomized trial. Methods: From April 2013 to May 2017, 331 patients from 22 hospitals who were pathologically confirmed with stage ⅢA-ⅣA ESCC were randomized to 60 Gy or 50 Gy with random number table. Total of 305 patients were analyzed, including 152 in 60 Gy group and 153 in 50 Gy group. The median age was 63 years, 242(79.3%) males and 63(20.7%) females. The median length of primary tumor was 5.6 cm. The clinical characteristics between two groups were comparable. All patients were delivered 2 Gy per fraction, 5 fractions per week. Concurrent weekly chemotherapy with docetaxel (25 mg/m(2)) and cisplatin (25 mg/m(2)) and 2 cycles consolidation chemotherapy with docetaxel (70 mg/m(2)) and cisplatin (25 mg/m(2), d1-3) were administrated. The primary endpoint was local/regional progression-free survival (LRPFS). The data were compared with Pearson chi-square test or Fisher's exact test. Results: At a median follow-up of 27.3 months, the disease progression rate was 37.5% (57/152), 43.8% (67/153) in the high and standard-dose group, respectively (χ(2)=1.251, P=0.263). The 1, 2, 3-year LRPFS rate was 75.4%, 56.8%, 52.1% and 74.2%, 58.4%, 50.1%, respectively (HR: 0.95, 95%CI: 0.69-1.31, P=0.761). The 1, 2, 3-year overall survival rate was 84.1%, 64.8%, 54.1% and 85.4%, 62.9%, 54.0%, respectively (HR: 0.98, 95%CI: 0.71-1.38, P=0.927). The 1, 2, 3-year progression-free survival rate was 70.8%, 54.2%, 48.5% and 65.5%, 51.9%, 45.1%, respectively (HR: 0.93, 95%CI: 0.68-1.26, P=0.621). The incidence rates in toxicities between the two groups were similar except for higher rate of severe pneumonitis in high dose group (χ(2)=11.596, P=0.021). Conclusions: The efficacy in disease control is similar between 60 Gy and 50 Gy using modern radiation technology concurrent with chemotherapy for ESCC. The 50 Gy should be recommended as the regular radiation dose with CCRT for ESCC.

Abstract
Abstract Objective To investigate the factors affecting changes of Symptom Check List-90 (SCL-90) of patients with traumatic subdural effusion. Methods One hundred and forty-two cases of patients with traumatic subdural effusion from the Center of Forensic Identification, Wannan Medical College collected from 2007-2018 were tested with SCL-90. The differences between SCL-90 results and the national norm and the influences of gender, age, education level, the number of effusion sites and location on SCL-90 results were analyzed. Results The differences between the scores of somatization, interpersonal sensitivity, depression, anxiety, hostility, terror, paranoia and psychosis factors and total mean scores in SCL-90 of traumatic subdural effusion and that of the national norm had statistical significance (P<0.05). The differences in depression and hostility factor scores between males and females had statistical significance (P<0.05). The differences in compulsion, anxiety and terror factor scores and total mean scores among different age groups had statistical significance (P<0.05). The differences in hostility, paranoia and psychosis factors among patients with different degrees of education had statistical significance (P<0.05). The differences in depression, anxiety, hostility and terror factor scores and total mean scores among single-site group, double-site group and multi-site group had statistical significance (P<0.05). The differences in somatization, depression and anxiety factor scores and total mean scores between the right cerebral hemisphere group and the left cerebral hemisphere group and bilateral hemisphere group had statistical significance (P<0.05). Conclusion Traumatic subdural effusion can cause certain psychological changes, which are related to the primary trauma of arachnoid tear as well as the number and location of effusion sites. Attention should be paid to the influence of the above factors during the assessment of psychological symptoms.

Abstract
Objective To evaluate the feasibility of arthroplasty with varisized three‐dimensional(3D) printing lunate prosthesis for the treatment of advanced Kienböck's disease (KD). Methods From 2016 November to 2018 September, a retrospective study was performed for the patients of KD in our hospital. Five patients (two males, three females) were included in this study. The mean age of the patients at the time of surgery was 51.6 years (range, 37–64 years). Varisized prosthesis identical to the live model in a ratio of 1:0.85, 1:1, and 1:1.1 were fabricated by 3D printing. All patients (one in Lichtman IIIA stage, two in Lichtman IIIB stage, one in Lichtman IIIC stage, and one in Lichtman IV stage) were treated with lunate excision and 3D printing prosthetic arthroplasty. Visual analog scale score (VAS), the active movement of wrist (extension, flexion) and strength were assessed preoperatively and postoperatively. The Mayo Modified Wrist Score (MMWS), Disabilities of the Arm, Shoulder and Hand (DASH) Score, and patient's satisfaction were evaluated during the follow‐up. Results Prosthesis identical to the live model in a ratio of 1:0.85 or 1:1 were chosen for arthroplasty. The mean operation time (range, 45 to 56 min) was 51.8 ± 4.44 min. Follow‐up time ranged from 11 months to 33 months with the mean value of 19.4 months. The mean extension range of the wrist significantly increased from preoperative 44° ± 9.6° to postoperative 60° ± 3.5° (P < 0.05). The mean flexion range of the wrist significantly increased from preoperative 40° ± 10.6° to postoperative 51° ± 6.5° (P < 0.05). The active movement of wrist and strength were improved significantly in all patients. VAS was significantly reduced from 7.3 preoperatively to 0.2 at the follow‐up visit (P < 0.05). The mean DASH score was 10 (range, 7.2–14.2), and the mean MMWS was 79 (range, 70–90). There were no incision infection. All patients were satisfied with the treatment. Conclusions For patients suffering advanced Kienböck's disease, lunate excision followed by 3D printing prosthetic arthroplasty can reconstruct the anatomical structure of the carpal tunnel, alleviate pain, and improve wrist movement.

The optimal analgesia regimen after laparoscopic colorectal cancer surgery is unclear. The aim of the study was to characterize the beneficial effects of continuous transversus abdominis plane (TAP) blocks initiated before operation on outcomes following laparoscopic colorectal cancer surgery.
Methods
Patients undergoing surgery for colorectal cancer were divided randomly into three groups: combined general–TAP anaesthesia (TAP group), combined general–thoracic epidural anaesthesia (TEA group) and standard general anaesthesia (GA group). The primary endpoint was duration of hospital stay. Secondary endpoints included gastrointestinal motility, pain scores and plasma levels of cytokines.
Results
In total, 180 patients were randomized and 165 completed the trial. The intention-to-treat analysis showed that duration of hospital stay was significantly longer in the TEA group than in the TAP and GA groups (median 4·1 (95 per cent c.i. 3·8 to 4·3) versus 3·1 (3·0 to 3·3) and versus 3·3 (3·2 to 3·6) days respectively; both P < 0·001). Time to first flatus was earlier in the TAP group (P < 0·001). Visual analogue scale (VAS) scores during coughing were lower in the TAP and TEA groups than the GA group (P < 0·001). Raised plasma levels of vascular endothelial growth factor C, interleukin 6, adrenaline and cortisol were attenuated significantly by continuous TAP block.
Conclusion
Continuous TAP analgesia not only improved gastrointestinal motility but also shortened duration of hospital stay. A decreased opioid requirement and attenuating surgical stress response may be potential mechanisms. Registration number: ChiCTR-TRC-1800015535 (http://www.chictr.org.cn).

Abstract
Objective: To evaluate the quality of life after Altemeier and Delorme procedures for rectal prolapse patients. Methods: A retrospective cohort study was performed. Clinical data of patients with full-thickness rectal prolapse undergoing surgical treatment in the Sixth Affiliated Hospital, Sun Yat-sen University from February 2013 to January 2018 were retrospectively analyzed. Patients who had no preoperative imaging data, who suffered from internal rectal intussusception, or who did not undergo Altemeier and Delorme operations were excluded. Sixty-seven patients were enrolled, including 32 males with median age of 20.5 (13, 34) years and 35 females with median age of 65.0 (50, 77) years. According to different procedures, patients were divided into the Altemeier group (48 cases) and the Delorme group (19 cases), who received standard Altemeier and Delorme operations respectively. The maximal prolapse length of preoperative squat position, the Longo constipation score, Wexner incontinence score, EQ-5D-5L score, postoperative complications and recurrence rate were analyzed and compared between two groups. Results: The maximal prolapse length of preoperative squat position in Altemeier group and Delorme group was (7.3±3.3) cm and (4.9±2.1) cm respectively with significant difference (t=2.907, P=0.005). The operations in both groups were successfully completed. The operation time and postoperative hospital stay of Altemeier group were longer than those of Delorme group [(112.3±47.0) minutes vs. (80.7±35.4) minutes, t=2.637, P=0.010; (11.3±5.0) days vs. (8.6±3.0) days, t=2.177, P=0.033]. The median follow-up period was 26 (13, 45) months. In the last follow-up, compared to pre-operation, the Longo constipation score [9.0 (6.0, 14.0) vs 4.0 (1.0, 6.5), Z=-4.989, P<0.001], Wexner incontinence score [0 (0, 5.5) vs. 0 (0, 2.0), Z=-3.325, P<0.001] and EQ-5D-5L score [45.0 (40.0, 57.5) vs. 80.0 (70.0, 87.5), Z=-5.587, P<0.001] were all improved obviously in the Altemeier group, meanwhile Longo constipation score [6.0 (5.0, 14.0) vs. 3.0 (1.0, 7.0), Z=-2.186, P=0.029], Wexner incontinence score [0 (0, 12.0) vs. 0 (0, 4.0), Z=-2.325, P=0.020] and EQ-5D-5L score [50.0 (35.0, 60.0) vs. 75.0 (65.0, 90.0), Z=-3.360, P=0.001] in the Delorme group were all improved obviously as well. The postoperative morbidity of complication between the two groups was not significantly different [10/48 (20.8%) vs. 4/19 (21.1%), χ(2)=0.049, P=0.826]. Sixteen patients (28.0%) relapsed after operation, including 10 patients in the Altemeier group and 6 patients in the Delorme group, without statistically significant difference (P=0.134). Conclusions: Both the Altemeier and Delorme procedures are effective treatments for rectal prolapse, which can improve the postoperative quality of life. Delorme procedure has the advantages of shorter operation time and faster postoperative recovery in patients with mild prolapse.

Abstract
Objective: To report the clinical features of anti-MDA5 antibody positive juvenile dermatomyositis (JDM) complicated with severe interstitial lung disease (ILD). Methods: The clinical data of three patients, who was admitted to the Department of Rheumatology and Immunology, Children's Hospital of the Capital Institute of Pediatrics from September 2016 to July 2017, with anti-melanoma differentiation associated gene 5 (MDA5) antibody positive JDM complicated with ILD were retrospectively extracted and analyzed. Meanwhile, PubMed database, CNKI, Wanfang database and China Biology Medicine disc (from their establishment to February 2019) with the key words "juvenile dermatomyositis" "interstitial lung disease" , and "anti-MAD5 antibody" both in English and Chinese were searched. Results: There were 2 females and 1 male (P1-P3), aged from 10 years 3 months to13 years 4 months, the time from onset to diagnosis were 2 months, 4 months and 10 months. All presented with rash. One of them had decreased muscle strength, and two had decreased activity tolerance. Creatine kinase was 588, 915 and 74 U/L, and serum ferritin were 1 792, >2 000 and 195.4 μg/L. All three patients had positive anti-MDA5 antibodies. At the time of diagnosis, all of them had ILD, pneumothorax and mediastinal emphysema, but had no respiratory symptoms. All three patients received oral methylprednisolone and cyclophosphamide pulse therapy, while human immunoglobulin was given only to P1 and P2. P1 developed rapid progressive pulmonary interstitial disease (RPILD) and died of respiratory failure after 2 months. While P2 and P3 were followed up for 1 to 2 years, who had complete remission, as anti-MDA5 antibody turned to negative and ILD improved significantly. Ten related reports in literature were retrieved, without reported Chinese cases, and most cases initiated with rash and very likely complicated with arthritis. Some of them were more likely to have ILD rather than muscle weakness. It also showed that Japanese JDM children had higher rate of positive anti-MDA5 antibody than patients from the U.S. and U.K., and are more susceptible to ILD and RPILD. The mortality rate of patients with RPILD is extremely high. Conclusions: The cases of JDM with positive anti-MDA5 antibody mainly presented with rash and mild muscle weakness, and could be complicated with ILD, pneumothorax and mediastinal emphysema without respiratory symptoms at early stage. Anti-MDA5 antibody titer is related to disease activity and can turn to negative after treatment.

Abstract
Objective: To compare the dosimetric parameters of three different modern radiation techniques in radical radiotherapy for esophageal cancer. Methods: A total of 25 patients with pathologically confirmed esophageal squamous cell carcinoma in Zhejiang Cancer Hospital were included from September 2015 to May 2016 and three radiation treatment plans for helical tomotherapy (TOMO), intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc therapy (VMAT) were designed respectively for each patient. Study patients included 24 males and 1 female,aged from 47 to 82 years old, with a median age of 63 years old. All patients received the total prescription dose of 60 Gy in 30 fractions to the planning target volume (PTV). Conformity index (CI), heterogeneity index (HI), D(1), D(2), D(50), D(95), D(98), D(9)9 and V(95), V(100), V(105) of PTV was calculated. The mean dose, V(5), V(10), V(20), V(30), V(40) and V(50) of total lung, heart, and maximum dose (D(max)) to spinal cord were recorded as well. Results: Compared with TOMO and IMRT, VMAT showed higher CI (0.81±0.08) and lower HI (0.10±0.05), and CI was worse in IMRT (0.77±0.05) than TOMO (0.79±0.04) (t=2.604, P=0.016) and VMAT (t=2.817, P=0.010). There was no significant difference in HI among three radiation techniques. The dosimetric parameters of TOMO in normal lung were significantly better than those of VMAT and IMRT, especially in V(20) and V(30). The D(max) of spinal cord (38.24±3.72) Gy in TOMO was significantly lower than that of the VMAT ((39.88±3.27)Gy, t=-3.173, P=0.004) and IMRT plan ((41.09±3.18)Gy, t=-5.559, P=0.000). Subgroup analysis showed that VMAT was superior to TOMO and IMRT in CI and HI, especially HI (0.09±0.01) significantly better than TOMO (0.12±0.03, t=3.024, P=0.029) and IMRT (0.12±0.02, t=-3.800, P=0.013) for patients with cervical and upper thoracic esophageal cancer. TOMO and VMAT were significantly better than IMRT in MLD, lung V(20) and V(30) (all P<0.05). TOMO (38.46±2.15)Gy was significantly superior to VMAT ((41.02±1.28)Gy,t=-2.701, P=0.043) and IMRT ((41.76±1.11)Gy, t=-3.111, P=0.027) at D(max) of the spinal cord. For the patients with middle and lower thoracic esophageal cancer, TOMO, VMAT and IMRT had no statistically significant differences in CI and HI. IMRT was inferior to TOMO and VMAT in MLD, lung V(10), V(20), and V(30) (all P<0.05). TOMO (38.17±4.14) Gy was significantly superior to VMAT ((39.52±3.64)Gy,t=-2.219, P=0.040) and IMRT ((40.87±3.59)Gy,t=-4.528, P=0.000) at D(max) of the spinal cord. Conclusions: The VMAT plan is better than TOMO and IMRT in terms of the conformal degree and dose uniformity of the target volume.TOMO seems significantly better than VMAT and IMRT in protecting normal tissue.

Abstract
Objective: To estimate the incidence, mortality and characteristics of cancer in Pearl River Delta Area of Guangdong Province between 2009-2013. Methods: Based on five population-based cancer registration data from Guangzhou, Shenzhen, Zhongshan, Jiangmen and Sihui spanning from 2009 to 2013, along with those corresponding population data, the incidence and mortality rates were estimated by gender and age groups. Chinese standard population derived from the 2000 Population Census and Segi's standard population were used for age-standardized incidence and mortality rates. Results: Between 2009 and 2013, the crude cancer incidence rate was 262.50/100 000, 274.76/100 000 in male and 249.49/100 000 in female. After adjusting for Chinese and Segi's standard population, the age-standardized incidence rates were 225.63/100 000 and 219.88/100 000, respectively. The crude mortality rate was 175.51/100 000, 222.92/100 000 in male and 127.46/100 000 in female, respectively. After adjusting for Chinese and Segi's standard population, the age-standardized mortality rates were 116.02 /100 000 and 114.31/100 000, respectively. The incidence rates were at low levels in the population less than 40 years old, thereafter went up rapidly with age especially in male, and then reached the peak in the population aged 80 and above. As with incidence, the mortality rates kept at low levels in the population before their 50 s and then rose up steadily with age until peaking in the 85+ age group. The most common cancers were female breast cancer, lung cancer, colorectal cancer, liver cancer and nasopharyngeal cancer with descending incidence rate. Lung cancer, liver cancer, colorectal cancer, female breast cancer and nasopharyngeal cancer were the top five cancer-attributable causes of death. Conclusions: Currently, Pearl River Delta Area were faced with huge cancer burden. Lung cancer, colorectal cancer, nasopharyngeal cancer, female breast cancer and male liver cancer are predominant cancers and more efforts should be made to fight against them.

Abstract
Objective: To study the in vitro activity of fosfomycin to extended-spectrum β-lactamases (ESBLs)-producing Escherichia coli and Klebsiella pneumoniae and to explore the mechanisms of fosfomycin resistance. Methods: A total of 1 052 ESBLs-producing E. coli(ESBL-EC) and K. pneumoniae(ESBL-KP) isolates were collected from bloodstream infections of 28 hospitals of 22 provinces and municipalities, which were stored by our laboratory.Minimum inhibitory concentrations (MICs) of fosfomycin against these clinical isolates were determined by agar dilution methods according to the Clinical and Laboratory Standards Institute (CLSI)(2015). The genes related to fosfomycin resistance were confirmed by Polymerase Chain Reaction (PCR) and sequencing. Results: The susceptibility rates of ESBL-EC and ESBL-KP isolates to fosfomycin were 91.3% (818/896) and 91.7% (143/156), respectively. A total of 91 fosfomycin-non-susceptible isolates were detected, of which 73 (80.2%) isolates carried fosA3 genes.Amongst 18 fosA3-negative isolates, 16 isolates were detected to have chromosomal mutations or insertion inactivation, while the rest two isolates had not been detected any resistant mechanisms. Conclusions: Fosfomycin shows great in vitro antimicrobial activity to ESBL-EC and ESBL-KP. The primary mechanism of fosfomycin-non-susceptible isolates is fosA3 gene.Chromosomal mutations may also involve in the fosfomycin resistance.

Abstract
Objective: To investigate the therapeutic effects and mechanisms of interleukin-10 (IL-10) gene-modified dendritic cells (DC-IL-10) in mice with liver fibrosis. Methods: DC-IL-10 was constructed in vitro, the phenotype and function of which were evaluated by flow cytometry. BALB/c mice were treated with intraperitoneal injection of carbon tetrachloride (CCl4) to establish liver fibrotic model. DC-IL-10 was administrated via tail vein. Animals were divided into 4 groups including normal dendritic cell(DC) control, liver fibrosis only, negative lentiviral transfection DC (DC-mock) and DC-IL-10. Liver function, cytokine secretion, T lymphocyte differentiation and liver histomorphology were tested. Real-time PCR and western blot were used to analyze the effect of DC-IL-10 on Wnt/β-catenin signaling pathway and its role in liver fibrosis. Results: When compared with DC control and DC-mock, the expression of DC-IL-10 surface stimulating molecules (major histocompatibity complex-Ⅱ, CD(80), CD(86)) were significantly decreased (F=14.708, 22.503, 12.595, respectively, all P<0.05), and DC-IL-10 significantly inhibited T lymphocyte proliferation (F=50.295, P<0.05). When compared with liver fibrosis group, serum alanine aminotransferase and aspartate transaminase were decreased in DC-IL-10 treated group (all P<0.05), other parameters including inflammatory factors (tumor necrosis factor α, IL-6, IL-1β) reduced (all P <0.05), the proportion of regulatory T cells (Treg) increased (F=6.742, P<0.05), pathological damage improved, the expression of Wnt3a, α-SMA and β-catenin mRNA and protein significantly reduced in DC-IL-10 treatment group (all P<0.001) . Conclusions: DC-IL-10 induces elevation of Treg for immune tolerance, as well as inhibition of inflammatory response, block of Wnt/β-catenin signaling pathway, which translates into improvement of liver fibrosis.

Abstract
Objective: To investigate a novel mutation in the HAND1 gene associated with sporadic dilated cardiomyopathy (DCM). Methods: From February 2013 to February 2017, the clinical data and peripheral venous blood samples were collected from 120 patients with sporadic DCM and 200 healthy controls, who were both from the Fifth People's Hospital of Shanghai, Fudan University and Shanghai Chest Hospital, Shanghai Jiaotong University.The genomic DNA was extracted from the study participants.The coding exons of HAND1 were amplified from the study subjects by polymerase chain reaction, and were sequenced for a potential HAND1 mutation.The online computer programs MUSCLE and Mutation Taster were used to analyze the conversation of an altered amino acid and to predict the disease-causing potential of an identified mutation, respectively.The wild-type HAND1 was cloned and the mutant was generated by site-directed mutagenesis.The Dual-luciferase reporter assay kits were used to explore the functional characteristics of the mutant HAND1. Results: A novel heterozygous mutation, a substitution of thymine for guanine at nucleotide 346 (c.346G>T), predicting the conversion of a glutamic acid-encoding codon into a stop codon at codon 116 (p.E116X), was detected in a patient with sporadic DCM.The nonsense mutation was absent in the 200 control individuals.The altered glutamic acid at amino acid position 116 was highly conserved evolutionarily, and the mutation was predicted to be pathogenic.Biological analyses revealed that the mutant HAND1 lost the ability to transcriptionally activate a target gene. Conclusion: Loss-of-function mutation in HAND1 is likely to be an uncommon cause responsible for sporadic DCM.

Abstract
Unconventional superconductivity often emerges at the border of long-range magnetic orders. Understanding the low-energy charge dynamics may provide crucial information on the formation of superconductivity. Here we report the unpolarized/polarized optical conductivity study of high quality MnP single crystals at ambient pressure. Our data reveal two types of charge carriers with very different lifetimes. In combination with the first-principles calculations, we show that the short-lifetime carriers have flat Fermi sheets which become gapped in the helimagnetic phase, causing a dramatic change in the low-frequency optical spectra, while the long-lifetime carriers are anisotropic three-dimensional like which are little affected by the magnetic transitions and provide major contributions to the transport properties. This orbital-dependent charge dynamics originates from the special crystal structure of MnP and may have an influence on the unconventional superconductivity and its interplay with helimagnetism at high pressures.

Abstract
When cells in G2 phase are challenged with DNA damage, several key mitotic regulators such as Cdk1/Cyclin B, Aurora A and Plk1 are inhibited to prevent entry into mitosis. Here we have studied how inhibition of Plk1 is established after DNA damage. Using a Förster resonance energy transfer (FRET)-based biosensor for Plk1 activity, we show that inhibition of Plk1 after DNA damage occurs with relatively slow kinetics and is entirely dependent on loss of Plk1-T210 phosphorylation. As T210 is phosphorylated by the kinase Aurora A in conjunction with its co-factor Bora, we investigated how they are affected by DNA damage. Interestingly, we find that the interaction between Bora and Plk1 remains intact during the early phases of the DNA damage response (DDR), whereas Plk1 activity is already inhibited at this stage. Expression of an Aurora A mutant that is refractory to inhibition by the DDR failed to prevent inhibition of Plk1 and loss of T210 phosphorylation, suggesting that inhibition of Plk1 may be established by perturbing recruitment of Aurora A by Bora. Indeed, expression of a fusion in which Aurora A was directly coupled to Bora prevented DNA damage-induced inhibition of Plk1 activity, as well as inhibition of T210 phosphorylation. Taken together, these data demonstrate that DNA damage affects the function of Aurora A at multiple levels: both by direct inhibition of Aurora A activity, as well as by perturbing the interaction with its co-activator Bora. We propose that the DDR targets recruitment of Aurora A to the Plk1/Bora complex to prevent activation of Plk1 during DNA damage in G2.

Abstract
Objective: To explore the treatment of senile osteoporotic femoral fractures after using internal fixation of bone cement dry prosthetic. Methods: Twelve patients aged from 74 to 94 years with mean age of (84.0±2.5) years with internal fixation of bone cement dry prosthetic surgery who were treated at Department of Orthopaedics in Nanjing Medical University Affiliated Wuxi Second Hospital between May 2013 and May 2015 were retrospectively analyzed. There were 8 male and 4 female, 10 cases of tumble and 2 cases of traffic injury. The fracture types with AO type included 1 case of A1 type, 5 cases of A2 type, 3 cases of A3 type, 1 case of B1 type, 2 cases of B2 type. The steel plate internal fixation with bone cement dry prosthetic method was chosen to treat senile severe femoral fracture. Postoperative observation of postoperative pain assessment, hip joint activity and walking ability were evaluated. Paired simple t test and Wilcoxon rank sum test were used to compare the differences of pain score and the ability to walk. Results: Twelve cases received an average of (16.0±3.6) months follow-up. The average hospitalization days are (9.0±1.4) days and average of intraoperative time was (68.0±10.6) minutes. Intraoperative blood loss compared to normal was (106.0±24.2) ml. Patients began walking load and activities in two weeks. The gait and joint activities gradually restored and there were no obvious deformity and no loose internal fixation. All of the patients didn't have fracture shift with breaking plates or screws deformation and have no bone cement reaction. The walking ability was (4.1±0.9) points, the hip joint activities were 98.5°±7.7° and pain scores were 1.22±0.58 by Holden grading standards. The differences of walking ability (Z=-3.126, P<0.05) and pain scores (t=23.047, P<0.001) between pre- and post-operative were statistically significant. One patient had contralateral hip pain, 2 patients had lateral thigh pain, 10 patients returned to preoperative level of activity. Postoperative function recovered satisfactorily, there were statistically differences. Conclusion: The treatment of severe osteoporosis fractures by internal fixation with bone cement dry prosthetic is a new and effective method, making patients less pain, improving joint function and walking ability.

Abstract
OBJECTIVE To evaluate the immunomodulating effect of oyster peptide on immunosuppressed mice. METHODS ICR mice injected with cyclophosphamide (CTX) were adopted as the module group, with mice without treatment as the control group, and different dosages of oyster peptide (0.5 g/kg, 1.0 g/kg, and 2.0 g/kg) were given to the low, middle, and high groups for 15 days. The body weight, spleen, and thymus weight of the mice, structures under the microscope of the immune organs, numbers of white blood cells, ratios of T lymphocyte subsets, immune cytokines and numbers of nuclear cells, and DNA content in bone marrow were all assessed. RESULTS Compared with the control group, the structures of thymus and spleen of the mice in the CTX group appeared obscure and shrunk when observed under microscope, the number of their white blood cells declined (P=0.04), the proportion of their CD3(+) T cells in peripheral blood declined (P=0.003), the proportion of their CD8(+) T cells in peripheral blood declined (P=0.002), the concentration of their IL-5 in peripheral blood significantly increased (P<0.01), the concentration of their nucleated cells and DNA density in bone marrow decreased (P=0.04, P<0.01). Oyster could improve the structures of thymus and spleen of the immunosuppressed mice. Compared with the CTX group, the number of white blood cells in 2.0 g/kg group increased (P=0.003), the proportion of CD3(+) T cells in peripheral blood in 1.0 g/kg group (P=0.04) and 2.0 g/kg group (P=0.02) increased, the proportion of CD8(+) T cells in peripheral blood in 2.0 g/kg group increased (P=0.002), the concentration of IL-5 in peripheral blood in all the oyster treated groups increased (P<0.01 in 0.5 g/kg, 1.0 g/kg, and 2.0 g/kg groups), the concentration of IL-17 in peripheral blood in 2.0 g/kg group decreased (P=0.03), the concentration of nucleated cells in bone marrow of all the oyster treated groups increased (0.5 g/kg vs. CTX, P=0.04; 1.0 g/kg vs. CTX, P=0.02; 2.0 g/kg vs. CTX P=0.01), the DNA content in bone marrow of all the oyster treated groups increased (P<0.01 in the 0.5 g/kg, 1.0 g/kg, and 2.0 g/kg groups). CONCLUSION Oyster peptide could improve the structures of immune organs of the CTX-induced immunosuppressed mice, recover the imbalances of T lymphocyte subsets, improve the immune cytokines and increase numbers of nucleated cells and DNA content in bone marrow, thus improving the immunologic function.

Abstract
OBJECTIVE To study the diversities of human B cell epitopes of five proteins (Mpt83, Mpt70, LpqH, PstS3, GroES) in Mycobacterium tuberculosis isolates from China. METHODS We selected 179 strains isolated from patients with tuberculosis in different regions of China, and cultured these strains by L-J medium. The gene sequences of these 5 proteins were amplified and sequenced by PCR. The variations (single nucleotide polymorphisms, SNP) of the DNA sequences were compared and analyzed according to the immune epitope database (IEDB). The synonymous mutation rate (dS), non-synonymous mutation rate (dN) and dN/dS values were calculated with MEGA6 software. RESULTS Among the 179 clinical MTBC isolates, 7 SNP mutations were found in the mpt83gene. The dN/dS value of the whole mpt83 gene was 0.88. One SNP mutation was found in the mpt70 gene. The dN/dS values of the whole pstS3 gene and non-B epitopes areas were 1.74 and 1.40 respectively. But no mutation was found in the groES gene. CONCLUSION The mpt83, lpqH and pstS3 genes of 179 MTBC strains contain gene SNPs and human B cell epitopes diversities, while the coding gene and human B cell epitopes of protein mpt70 and groES were conservative.

Abstract
Neutral beam injection has been recognized as one of the most effective means for plasma heating. According to the research plan of the EAST physics experiment, two sets of neutral beam injector (NBI) were built and operational in 2014. The paper presents the development of beam diagnosis system for EAST NBI and the latest experiment results obtained on the test-stand and EAST-NBI-1 and 2. The results show that the optimal divergence angle is (0.62°, 1.57°) and the full energy particle is up to 77%. They indicate that EAST NBI work properly and all targets reach or almost reach the design targets. All these lay a solid foundation for the achievement of high quality plasma heating for EAST.

Abstract
UNLABELLED The aim of the study was to review patients characteristics, describe the exact anatomic locations and size of the endometriosis in the abdominal wall, and discuss the factors that may contribute to mesh use during abdominal wall endometriosis (AWE) resection. MATERIALS AND METHODS Patients diagnosed with AWE in their surgical scars from January 2008 to December 2014 were documented. Descriptive data was collected and analyzed. RESULTS A total of 95 patients with an age ranging from 26 to 48 years, with a mean age of 33.5 ?5.0 years at the time of excision were analyzed. The mean diameter of the mass was 3.25 cm in the present series with an average of 4.97 cm in the mesh group by ultrasound. A total of 18 patients had mesh therapy for fascia defect compared with 77 non-mesh therapy patients. The size of the lesions, the mean duration of symptoms for painful mass, and level of the serum CA125 were statistically different between mesh group and non-mesh group (p < 0.05). Cases of endometriosis lesions limited to the adipose layer had significant lower chance of using mesh (p < 0.05). However, adipose layer endometriosis lesions that had penetrated through the fascia layer and invaded into rectus abdominis muscle layer with/without peritoneum layer had significant higher chance of using mesh (p < 0.05). CONCLUSIONS The more common position for scar endometriosis may be in the adipose layer at the corner of the surgical scar. Mesh therapy should be considered before surgery when the diameter of the abdominal wall mass detected by ultrasound is more than five em and/or when the lesions invade into rectus abdominis muscle with/without peritoneum tissues from adipose and fascia layers.

Abstract
Lung cancer ranks as the first most common cancer and the first leading cause of cancer-related death in China and worldwide. Due to the difficulty in early diagnosis and the onset of cancer metastasis, the 5-year survival rate of lung cancer remains extremely low. Long noncoding RNAs (lncRNAs), which lacking protein-coding ability, have recently emerged as pivotal participants in biological processes, often dysregulated in a range of cancers, including lung cancer. In this review, we highlight the recent findings of lncRNAs in lung cancer pathogenesis. While our understanding of lncRNAs in the onset and progression of lung cancer is still in its infancy, there is no doubt that understanding the activities of lncRNAs will certainly secure strong biomarkers and improve treatment options for lung cancer patients.

Abstract
Tumour cell proliferation, invasion and apoptosis are crucial steps in tumour metastasis. We evaluated the effect of serum from patients undergoing colon cancer surgery receiving thoracic epidural and propofol anaesthesia on colon cancer cell biology. Patients were randomly assigned to receive propofol anaesthesia with a concomitant thoracic epidural (PEA, n = 20) or sevoflurane anaesthesia with opioid analgesia (SGA, n = 20). Venous blood was obtained before induction of anaesthesia and 24 hours postoperatively. The LoVo colon cancer cells were cultured with patient serum from both groups and the effects on proliferation, invasion and apoptosis were measured. Twenty-four hours after surgery, the absorbance value of LoVo cells at 10% serum concentration from PEA was decreased when compared with SGA (0.302 (0.026) vs 0.391 (0.066), p = 0.005). The inhibitory rate of LoVo cells at 10% serum concentration from PEA was higher than that from SGA (p = 0.004) 24 h after surgery. The number of invasive LoVo cells at 10% serum concentration from PEA was reduced when compared with SGA (44 (4) vs 62 (4), p < 0.001). Exposure of LoVo cells to postoperative serum from patients receiving PEA led to a higher luminescence ratio (apoptosis) than those receiving SGA (0.36 (0.04) vs 0.27 (0.05), p < 0.001). Serum from patients receiving PEA for colon cancer surgery inhibited proliferation and invasion of LoVo cells and induced apoptosis in vitro more than that from patients receiving SGA. Anaesthetic technique might influence the serum milieu in a way that affects cancer cell biology and, thereby, tumour metastastasis.

Abstract
We determined whether genetically engineered immature dendritic cells (imDCs) mediated by lentiviral vectors alleviate acute graft-versus-host disease (GVHD) after allogeneic bone marrow transplantation (allo-BMT) in mice. We introduced the mouse chemokine receptor 7 (Ccr7) gene into the bone marrow-derived imDCs of C57BL/6 mice to construct genetically engineered imDCs. A 1:1 mixture of bone marrow and spleen cells from the donors was injected into the recipients, which were divided into four groups: radiation, transplantation, empty vector, and transgenic imDC groups. Symptoms, clinical scores, GVHD pathological changes, and survival times and rates of recipients were recorded; secretion of IFN-γ and IL-4, and allogeneic chimerism rates were detected. The survival time of the transgenic imDC group (27.5 ± 7.55 days) was significantly longer than in the other three groups (P < 0.01). The GVHD score of the imDC group mice was significantly lower than in the transplantation and empty vector groups (P < 0.05), which meant that mice in the transgenic imDC group had the lightest pathology damage in the target organs. In the transplantation group, IFN-γ increased while IL-4 decreased. In contrast, IFN-γ decreased and IL-4 increased in both empty vector and trans-imDC groups, and the difference was significant in the latter (P < 0.01). Thirty days or more following transplantation, the allogeneic chimerism rate was still 95-100%, suggesting complete donor type implantation. Ccr7 transfection into imDCs suppressed occurrence and severity of acute GVHD after allo-BMT in mice; the mechanism might be associated with IFN-γ decrease and IL-4 increase.
