Abstract
BACKGROUND The prognostic value of cytokeratin 19 fragment (CYFRA 21 - 1) and Ki67 in advanced non-small cell lung cancer (NSCLC) patients with wild-type epidermal growth factor receptor (EGFR) remains to be explored. METHODS In this study, 983 primary NSCLC patients from January 2016 to December 2019 were retrospectively reviewed. Finally, 117 advanced NSCLC patients with wild-type EGFR and 37 patients with EGFR mutation were included and prognostic value of CYFRA 21 - 1 and Ki67 were also identified. RESULTS The patients age, smoking history and the Eastern Corporative Oncology Group (ECOG) performance scores were significantly different between CYFRA21-1 positive and negative groups (p < 0.05), while no significant differences were found in Ki67 high and low groups. The results of over survival (OS) demonstrated that patients with CYFRA21-1 positive had markedly shorter survival time than CYFRA21-1 negative (p < 0.001, For whole cohorts; p = 0.002, For wild-type EGFR). Besides, patients with wild-type EGFR also had shorter survival times than Ki67 high group. Moreover, In CYFRA 21 - 1 positive group, patients with Ki67 high had obviously shorter survival time compared to patients with Ki67 low (median: 24vs23.5 months; p = 0.048). However, Ki67 could not be used as an adverse risk factor for patients with EGFR mutation. Multivariate cox analysis showed that age (HR, 1.031; 95%CI, 1.003 ~ 1.006; p = 0.028), Histopathology (HR, 1.760; 95%CI,1.152 ~ 2.690; p = 0.009), CYFRA 21 - 1 (HR, 2.304; 95%CI,1.224 ~ 4.335; p = 0.01) and Ki67 (HR, 2.130; 95%CI,1.242 ~ 3.652; p = 0.006) served as independent prognostic risk factor for advanced NSCLC patients. CONCLUSIONS Our finding indicated that CYFRA 21 - 1 was an independent prognostic factor for advanced NSCLC patients and Ki67 status could be a risk stratification marker for CYFRA 21 - 1 positive NSCLC patients with wild-type EGFR.

Abstract
Objective: To investigate the correlation between dyslipidemia and the risk of papillary thyroid carcinoma (PTC). Methods: A case-control study was conducted. PTC patients diagnosed by pathology in Tianjin Medical University Cancer Institute and Hospital from April 2014 to August 2019 were enrolled as the experimental group, and healthy controls in the physical examination center at the same time were also enrolled as the control group. The demographic data and blood lipid parameters of the subjects were collected. Multivariate logistic analyses were used to assess the correlation between dyslipidemia and the risk of PTC. Results: A total of 2 000 cases of PTC were enrolled, with a mean age of (42±12) years, including 1 419 females (71.0%) and 581 males (29.0%). There were 4 524 cases in the control group, with a mean age of (42±9) years, including 3 311 females (73.2%) and 1 213 males (26.8%). There was no statistically difference in age and gender between the two groups (both P>0.05). Compared with the control group, triglyceride (TG) [(1.7±1.1) vs (1.4±1.0) mmol/L, P<0.001] and low-density lipoprotein (LDL) [(2.9±0.8) vs (2.8±0.7) mmol/L, P=0.015] increased in peripheral blood of PTC patients, while high-density lipoprotein (HDL) [(1.3±0.4) vs (1.4±0.3) mmol/L, P<0.001] decreased, but the difference was not statistically significant in total cholesterol (TC) [(4.9±1.0) vs (4.9±0.8) mmol/L, P=0.172]. After adjusting for age and gender, increase of TC (OR=1.20, 95%CI: 1.06-1.34, P=0.003), TG (OR=1.73, 95%CI: 1.55-1.94, P<0.001), LDL (OR=1.21, 95%CI: 1.08-1.36, P=0.001), LDL/HDL (OR=1.77, 95%CI: 1.56-2.02, P<0.001) and decrease of HDL (OR=3.15, 95%CI: 2.78-3.58, P<0.001) were the related factors of PTC. Conclusions: Compared with the control group, patients with PTC have higher level of TG and LDL and lower level of HDL. Dyslipidemia is an important factor related to the risk of PTC.

Abstract
Objective: To analyze the risk factors of recurrence or metastasis of medullary thyroid carcinoma (MTC) and the influencing factors of disease-free survival (DFS). Methods: The clinicopathological data of MTC patients who visited Tianjin Medical University Cancer Institute and Hospital and underwent surgery from August 2014 to August 2019 were retrospectively analyzed. The patients were divided into recurrence or metastasis group and no recurrence or metastasis group. Multivariate logistic regression analysis was used to analyze the risk factors for recurrence or metastasis. Kaplan-Meier survival analysis and Cox regression analysis were used to determine the risk factors of DFS. Results: A total of 158 MTC patients were enrolled in final analysis, including 83 females and 75 males, with a median age of 52 (19-74) years. There were 146 cases of sporadic MTC (92.4%) and 12 cases of familial MTC (7.6%), respectively. Bilateral thyroid lesions presented in 33 cases (20.9%) and multiple lesions presented in 57 cases (36.1%), respectively. The median follow-up time was 59.7 (10.0-93.0) months and the median DFS was 55.5 (0-92.9) months. Presence of multifocality, the largest tumor size>2 cm, T3/4, N1b, clinical stage Ⅲ/Ⅳ, lymph node metastasis ratio (LNR)>0.3, preoperative calcitonin>2 000 ng/L, postoperative calcitonin>40 ng/L and no biochemical cure were significantly correlated with the recurrence or metastasis and DFS of MTC (all P<0.05). Clinical stage Ⅲ/Ⅳ (OR=36.57, 95%CI: 1.33-1 006.98, P=0.033), the largest tumor size>2 cm (OR=5.81, 95%CI: 1.01-33.33, P=0.049), multifocality (OR=3.64, 95%CI: 1.03-12.88, P=0.045) and postoperative calcitonin>40 ng/L (OR=15.03, 95%CI: 1.39-162.61, P=0.026) were independent risk factors of recurrence or metastasis. Clinical stage Ⅲ/Ⅳ (HR=19.39, 95%CI:1.40-268.19, P=0.027), the largest tumor size>2 cm (HR=3.64, 95%CI: 1.02-13.02, P=0.047) and postoperative calcitonin>40 ng/L (HR=10.68, 95%CI: 1.34-84.95, P=0.025) were influencing factors for DFS (all P<0.05). Conclusion: The larger tumor size, advanced clinical stage and higher postoperative calcitonin at the initial treatment of MTC are risk factors for recurrence or metastasis and influencing factors for DFS.

Abstract
Objective: To analyze the correlations between serum thyroglobulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) and clinicopathological features in children and adolescents with papillary thyroid carcinoma (PTC). Methods: A retrospective analysis was conduced on the clinicopathological data of children and adolescents (age≤21 years old) with PTC admitted to Tianjin Medical University Cancer Hospital from 2011 to 2019, and then, we used χ2 test or Fisher's exact probability test to compare the differences in clinicopathological characteristics between groups with different TgAb and TPOAb status and multivariate logistic regression model analysis to evaluate independent predictors of cervical lymph node metastasis. Results: A total of 304 patients, including 89 males and 215 females, aged 5-21 years (median age 19 years), were enrolled in this study. The comparison between groups with different TgAb and TPOAb status showed that there were significant differences in gender, preoperative thyroglobulin (Tg) level, primary tumor location, number of primary tumors and maximum tumor diameter (all P<0.05), which suggested that TgAb+group (n=81) and TPOAb+group (n=84) had relatively better primary tumor characteristics. Patitents with TgAb+and TPOAb+were more common in females and their preoperative Tg level was mostly within the normal range, and there were significant differences in primary tumor location, number of primary tumors and maximum tumor diameter between TgAb+and TgAb-(223 cases) groups (all P<0.05). There was significant difference in the maximum tumor diameter between TPOAb+and TPOAb-(220 cases) groups (P<0.05). Analysis of risk factors for cervical lymph node metastasis showed that independent risk factors for central lymph node metastasis were maximum tumor diameter>2 cm (OR=2.84, 95%CI: 1.59-5.07, P<0.001) and extra-thyroid extension (OR=0.32, 95%CI: 0.17-0.60, P<0.001), and independent risk factors for lateral neck lymph node metastasis included age≤14 years old (OR=0.34, 95%CI: 0.18-0.67, P=0.002), preoperative Tg+(OR=2.16, 95%CI: 1.10-4.24, P=0.026) and maximum tumor diameter>2 cm (OR=3.99, 95%CI: 2.33-6.82, P<0.001). Conclusion: It is recommended to test routinely serum TgAb and TPOAb before surgery in children and adolescents with PTC. Preoperative Tg+, age≤14 years, maximum tumor diameter>2 cm, and extra-thyroid extension are risk factors for cervical lymph node metastasis.

Abstract
Objective: To investigate the incidence, characteristics and risk factors of spinal epidural hematoma after unilateral biportal endoscopic (UBE) lumbar spine surgery. Methods: The clinical data of 105 patients who underwent lumbar spine surgery under UBE in Guangdong Provincial People's Hospital from February 2020 to March 2021 were retrospectively reviewed. Of the patients, 48(45.7%) were male and 57(54.3%) were female, the mean age was (60.1±11.4) years (ranged 26 to 85 years). The MRI images at the third day post-surgery were observed, and the occurrence of hematoma was counted. Patients were assigned to normal group and hematoma group based on the presence of hematoma or not. The related clinical indicators of each patients were collected and used for comparison between two different groups. Logistic stepwise regression model was used to analyze whether each index was a risk factor for hematoma after the UBE lumbar fusion. Results: The total hematoma incidence rate was 28.6%(30/105), the symptomatic hematoma rate was 6.7%(7/105), and the hematoma reoperation rate was 0.9%(1/105). Univariate logistic regression analysis showed that hypertension (OR=3.368, 95%CI: 1.389-8.171), diabetes (OR=3.589, 95%CI: 1.230-10.476), admission systolic blood pressure>140 mmHg (1 mmHg=0.133 kPa,OR=3.687, 95%CI: 1.493-9.017), platelets<200×109/L (OR=0.300, 95%CI: 0.119-0.785), preoperative blood calcium<2.25 mmol/L (OR=0.340, 95%CI: 0.142-0.818), spinal stenosis grade D (OR=4.462, 95%CI: 1.810-10.996) were possible risk factors for spinal hematoma after UBE lumbar fusion. Multivariate logistic regression analysis showed that admission blood pressure systolic blood pressure>140 mmHg (OR=3.788, 95%CI:1.055-13.606), preoperative blood calcium<2.25 mmol/L (OR=78.544, 95%CI:3.895-1 584.058) and spinal stenosis grade D (OR=3.698, 95%CI:1.110-12.325) were risk factors for spinal hematoma after UBE lumbar fusion (all P<0.05). Conclusion: The types of spinal canal hematoma after UBE lumbar fusion include localized and extended type. The risk factors for hematoma include high systolic blood pressure on admission, low preoperative blood calcium and severe spinal stenosis.

Abstract
BACKGROUND Microbial Translocation (MT) and altered gut microbiota are involved in immune activation and inflammation, whereas immune checkpoint proteins play an important role in maintaining immune self-tolerance and preventing excessive immune activation. OBJECTIVE This study aims to investigate the relationship between plasma phage load and immune homeostasis in people living with HIV(PLWH). METHODS We recruited 15 antiretroviral therapy (ART)-naive patients, 23 ART-treated (AT) patients, and 34 Healthy Participants (HP) to explore the relationship between the plasma phage load and immune checkpoint proteins. The Deoxyribonucleic Acid (DNA) load of the lambda (λ) phage was detected using fluorescence quantitative Polymerase Chain Reaction (PCR). The Immune Checkpoints (ICPs) were detected using multiplex immunoassay. RESULTS Our study demonstrated that the plasma phage load was increased in people living with HIV (PLWH) (P<0.05), but not in the ART-naive and AT groups (P>0.05). Plasma ICPs, including cluster of differentiation 27 (CD27), soluble glucocorticoid-induced Tumor Necrosis Factor (TNF) receptor (sGITR), soluble cluster of differentiation 80 (sCD80), sCD86, soluble glucocorticoidinduced TNF receptor-related ligand (sGITRL), soluble induced T-cell Costimulatory (sICOS), sCD40, soluble toll-like receptor 2 (sTLR2), and sCD28, were markedly decreased among the ARTnaive group (P<0.05) but not in the AT and HP groups (P>0.05). The plasma phage load was positively correlated with ICP and C-reactive protein (CRP) levels in PLWH (P<0.05). CONCLUSION Our study indicated that the plasma phage load in PLWH was positively related to the expression of ICPs and inflammation, which may be used as a promising marker for the immune level of PLWH.

Abstract
BACKGROUND AND AIMS Hepatitis B virus (HBV) is a common viral pathogen that infects more than a third of the world's population; however, the transmission route remains to be further defined. The 18-year implementation of free HBV vaccine for children has greatly changed the prevalence of HBV infection in China, which presents a unique real-world model for assessing the pattern of HBV transmission. METHODS Cross-sectional data of HBV seromarkers between July 2019 and April 2020 were collected from 53,371 individuals aged 1-60 years in four areas of North to South in Eastern China. Longitudinal data of HBV seromarkers between 2007 and 2020 were collected from 177 adults in an area of South China. The regional- and age-specific changes in HBV seromarkers were analyzed. RESULTS Overall, positive rates of HBV surface antigen (HBsAg) (from 3.44% to 15.1%) and antibody against HBV core antigen (anti-HBc) (from 7.6% to 44.0%) significantly increased from North to South. Among persons aged ≤18 years, the positive rates of antibody against HBsAg (anti-HBs) and anti-HBc (+) remained at low levels in the North, while they were increasing among persons aged >12 years in the South, despite higher positive rates of anti-HBs (+). Among persons aged >18 years, the anti-HBs (+) rates remained relatively stable (~60%), while anti-HBc (+) rates increased significantly with age. Up to ~80% of the anti-HBs (+) adults in the South was anti-HBc (+) while it was 13.6% in the North. In the longitudinal cohort, the anti-HBc (+) rate among adults in the South increased by 14.2% during 10 years of follow-up. CONCLUSION Horizontal transmission might be a common route in highly endemic areas, and may help to explain the high HBV exposure worldwide. The risk of horizontal transmission among children without seroprotective anti-HBs should be notified in highly endemic areas. This article is protected by copyright. All rights reserved.

Abstract
Purpose Red blood cell distribution width (RDW) has been considered as a potential indicator of the effects of treatment or as a prognostic indicator for various malignancies. Most chronic myeloid leukemia (CML) patients are in the chronic phase, but some have transformed to accelerated phase or blast phase (blast crisis). However, the clinical significance of RDW in CML remains limited. Patients and Methods In the present study, detailed clinical information and the RDW of 168 healthy people and 153 CML patients (106 patients for the training cohort and 47 patients for the validation cohort) were retrospectively assessed. Results Multivariate analysis demonstrated that patient age (OR, 1.081; 95CI% 1.039~1.125; p < 0.001), platelet counts (OR, 0.997; 95CI% 0.994~0.999; p = 0.001) and RDW at admission (OR,1.469; 95CI% 1.121~1.925; p = 0.005) were significantly associated with the patients with advanced phase. Among CML patients in the chronic phase, higher RDW was significantly associated with overall survival (OS; p = 0.0008) and the event-free survival (EFS; p = 0.0221) among CML patients with chronic phase, but not with Transformation-free survival (TFS; p = 0.0821). Furthermore, higher RDW was associated with higher mortality compared to patients with low RDW (CML-associated deaths; p < 0.0001). In addition, a decline in RDW is associated with the treatment of CML patients with tyrosine kinase inhibitors, especially at 6 and 12 months after the start of treatment. Conclusion Higher RDW is a potential prognostic biomarker for chronic CML patients.

Abstract
Background: Immune thrombocytopenia (ITP) is characterized by non-chronic (transient, <12 months) and chronic (≥12 months) decline in the number of platelets. Herpes virus infections have been shown, in many studies, to be associated with the development of ITP. However, it remains unclear whether the herpes virus infection status is associated with the chronic ITP. Methods: We reviewed 480 primary pediatric patients with ITP in the period from January 2017 to December 2019. The prevalence of herpes virus antibodies including the Cytomegalovirus (CMV), Herpes simplex virus 1 (HSV-1), Herpes simplex virus 2 (HSV-2), and Epstein Barr virus were recorded. The levels of serum complement C3 and C4, T (CD3+, CD4+, CD8+), B (CD19+) lymphocytes, and natural killer (CD16+ 56+) cells were also analyzed. Multivariate analysis was used to evaluate the associations between chronic ITP and herpes virus infection status. Results: Compared with non-chronic, patients with chronic ITP had older age (≥3 years), lower levels of hemoglobin and complement C3, and lower probability of CMV and HSV-2 infections (IgM positive; p < 0.05). Patients with herpes virus infection had lower serum platelet counts (p < 0.001), lower complement C3 levels and lower CD4+/CD8+ cells ratio (p < 0.05). Furthermore, platelet counts were positively correlated with CD4+/CD8+ cells ratios (r = 0.519; p = 0.0078), and negatively correlated with T cells (CD3+: r = -0.458, p = 0.0213; CD8+: r = -0.489, p = 0.0131). Multivariate analysis showed that age (OR, 1.644; 95%CI, 1.007-2.684; p = 0.047) was an adverse risk factor for chronic ITP and CMV IgM positive (OR, 0.241; 95%CI, 0.072-0.814; p = 0.022) had lower risk of chronic ITP development, while other herpes virus infection statuses and clinical features were not. Conclusion: Although herpes virus infections were associated with the onset of ITP, our findings indicated that herpes virus infection status might not be a risk factor for chronic ITP.

Abstract
Microbial translocation (MT) and altered gut microbiota have been described in acute leukemic patients and contribute to immune activation and inflammation. However, phage translocation has not been investigated in leukemia patients yet. We recruited 44 leukemic patients and 52 healthy adults and quantified the levels of 3 phages in peripheral blood, which were the most positive phages screened from fecal samples. The content of 16S rRNA in plasma was detected by qPCR to assess the intestinal mucosa of these patients. Spearman's rank correlation was used to analyze the relationship between phage load and the relevant clinical data. We found the most prevalent phages in fecal samples were λ phage, Wphi phage, and P22 phage, and λ phage had the highest detection rate in plasma (68%). Phage content was affected by chemotherapy and course of disease and correlated with the levels of CRP (r = 0.43, p = 0.003), sCD14 (r = 0.37, p = 0.014), and sCD163 (r = 0.44, p = 0.003). Our data indicate that plasma phage load is a promising marker for gut barrier damage and that gut phage translocation correlates with monocyte/macrophage activation and systemic inflammatory response in leukemic patients.

Abstract
Human cytomegalovirus (HCMV) is an opportunistic prototypic beta-herpesvirus that can cause severe and even fatal diseases in immune-naive newborns and immunocompromised adults. Host-virus interactions occurring at the transcriptional and posttranscriptional levels are critical for establishing an HCMV latent or lytic infection, but the mechanisms remain poorly understood. Herein, we investigated the expression of circRNAs in human leukemia monocytes (THP-1 cells) latently infected with HCMV and explored the diagnostic value of circRNAs in children with HCMV infection. A total of 2,110 and 1,912 circRNAs were identified in mock-infected and HCMV latent-infected THP-1 cells, respectively. Of these, we identified 1,421 differently expressed circRNAs, of which 650 were upregulated and 771 were downregulated. The host genes corresponding to the differentially expressed circRNAs were mainly involved in the regulation of host cell secretion pathways, cell cycle, and cell apoptosis. The differentially expressed circRNAs had binding sites for microRNAs, suggesting an important role in the mechanism of HCMV latent infection. Furthermore, a clinical analysis showed that the expression levels of hsa_circ_0001445 and hsa_circ_0001206 were statistically significantly different in HCMV-infected patients vs. normal controls, suggesting that these circRNAs could potentially serve as biomarkers of HCMV-infection.

Abstract
Objective: To evaluate the efficacy of ultrasound guided quadratus lumborum block combined with non-steroidal anti-inflammatory drugs for postoperative analgesia in patients undergoing total hip arthroplasty. Methods: From January to June 2017, sixty American Society of Anesthesiologists (ASA) physical status Ⅰ to Ⅲ patients, aged 55-75 yr, scheduled for total hip arthroplasty, were randomly divided into control group(group N) and quadratus lumborum block (group R). Ultrasound guided quadratus lumborum block was implemented on the affected side at the end of operation.Then 30 ml 0.33% ropivacaine were administrated in group R, while the control group did not receive the same block. A sufentanil patient-controlled analgesia pump was connected to the patient. The rest visual analogue score (VAS) were recorded at 0 h(T(0)), 3 h(T(1)), 6 h (T(2)), 12 h(T(3)), 24 h (T(4)), 36 h (T(5)) and 48 h(T(6)) after sugery, the VAS scores on movement were evaluated at T(4), T(5) and T(6) time points.The consumption of sufentanil within each period time were recorded.The maximal flexion and abduction degrees of the hip joint were evaluated at 12, 24, 36 and 48 h after operation. The number of patients for rescue pain relief by intravenous analgesia pump during 24 h and 48 h after surgery were counted in both groups. The postoperative adverse effects and overall satisfaction in the two groups were recorded. Results: The VAS at rest in group R were 0.8±0.4, 1.0±0.3, 1.2±0.5, 2.0±0.5, 1.7±0.4 , 1.6±0.5 at T(1), T(2), T(3), T(4), T(5), T(6) respectively, and those in group N were 3.0±0.7, 3.5±0.9, 3.8±0.9, 3.3±1.1, 3.3±0.7, 3.0±0.7 at the same time points. The VAS at rest were lower in group R than those in control group at all time points (F=203.090, 216.354, 203.956, 35.548, 96.332, 80.577, all P<0.01). The VAS on movement in group R were 2.7±0.9, 2.9±0.7 , 2.0±0.6 at T(4), T(5), T(6) respectively , and those in group N were 6.0±1.5, 5.8±1.1, 4.5±1.0. The VAS on movement were also lower in group R than those in control group(F=154.561, 143.224, 141.479, all P<0.01). The maximum flexion degrees in group R were (61±12)degrees, (64±10)degrees, (69±15)degrees and(78±19)degrees at 12, 24, 36, 48 h after operation, and those were (45±11) degrees, (49±10)degrees, (52±12)degrees and(60±14)degrees at the same time points. The maximum flexion degrees in group R were increased more than control group at 12, 24, 36, 48 h after operation(F=34.981, 35.575, 52.106, 41.681, all P<0.01). The abduction degrees in group R were(22±6)degrees, (26±6)degrees, (27±8)degrees and(28±7)degrees at 12, 24, 36, 48 h after surgery, and those in group N were (14±5) degrees, (17±6)degrees, (20±6)degrees and(20±5)degrees. The abduction degrees in group R were increased more than those in group N(F=58.974, 33.402, 19.151, 20.575, all P<0.01). The rates of rescue analgesia for pain relief were 10% and 16.7% at 24 h and 48 h after operation respectively in group R, and those were 100% and 100% in group N. Compared to group N, the rates of rescue analgesia for pain relief in group R were significantly decreased (χ(2)=49.091, 42.857, all P<0.01). The incidences of postoperative nausea and vomiting, pruritus in group R were 3.3% and 3.3% respectively, and those in group N were 23.3% and 20.0%. The incidences of nausea and vomiting, pruritus in group R were lower than those in group N (χ(2)=5.192, 4.875, all P<0.01). The overall satisfaction scores in group R (3.7 ± 1.0 ) were higher than those (1.9±0.7) in the group N(t=7.841, P<0.01). Conclusion: The quadratus lumborum block combined with parecoxib sodium for multimodal analgesia after total hip arthroplasty is effective and provides satisfactory analgesia.

Abstract
Long non‑coding RNAs (lncRNAs) are crucial factors in acute promyelocytic leukemia (APL) cell differentiation. However, their expression patterns and regulatory functions during all‑trans‑retinoic acid (ATRA)‑induced APL differentiation remain to be fully elucidated. The profile of dysregulated lncRNAs between three bone marrow (BM) samples from patients with APL post‑induction and three BM samples from untreated matched controls was examined with the Human Transcriptome Array 2.0. The dysregulated lncRNA expression of an additional 27 APL BM samples was validated by reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) analysis. The lncRNA functions were predicted through co‑expressed messenger RNA (mRNA) annotations. Co‑expressed lncRNA‑mRNA networks were constructed to analyze the functional pathways. In total, 825 lncRNAs and 1,218 mRNAs were dysregulated in the treated APL BM group, compared with the untreated APL BM group. The expression of 10 selected lncRNAs was verified by RT‑qPCR analysis. During APL differentiation, NONHSAT076891 was the most upregulated lncRNA, whereas TCONS_00022632‑XLOC_010933 was the most downregulated. Functional analysis revealed that several lncRNAs may exert activities in biological pathways associated with ATRA‑induced APL differentiation through cis and/or trans regulation of mRNAs. The findings of the present study assist in explaining the contributions of lncRNAs in APL myeloid differentiation and improve current knowledge on the potential mechanisms regarding dysregulated lncRNA expression in ATRA‑induced APL differentiation.

Abstract
Objective: To estimate the prevalence of eczema in early childhood and effect of infant feeding practice on eczema by different regions of China with diverse climate and dietary patterns. Method: A questionnaire survey was conducted from June 2012 to October 2012 in Shanghai, Hohhot, and Fuzhou. The parent or guardian of the children aged between 2.5 to 3.5 years attending routine health visit in the chosen communities were invited to complete a modified questionnaire of the International Study of Asthma and Allergy in Childhood (ISAAC). Logistic regression model was used to analyze of the family history of allergy, duration of breastfeeding, timing of introduction of complementary foods and other potential confounders. Result: A total of 2 242 children were interviewed, 750 from Shanghai, 716 from Hohhot, and 776 from Fuzhou. The prevalence of eczema in early childhood was significantly different among Shanghai (16.9%, 95%CI 16.87-16.93), Hohhot (34.5%, 95%CI 34.46-34.54)and Fuzhou (44.3%, 95%CI 44.26-44.34). The difference was statistically significant between 3 groups (χ2=72.05, P<0.05). Introducing complementary food after the age of 6 months was associated with a decreased risk for eczema when compared to introduction between 4 to 6 months(odds ratio (OR) 0.58, 95%CI 0.41-0.81) in Fuzhou, while there was no significant association between timing of introduction of complementary foods and eczema in Shanghai and Hohhot. Conclusion: The prevalence of eczema during early childhood is various among three cities. The relationship between timing of introduction of complementary foods and eczema in Fuzhou is different from that in Shanghai and Hohhot. The role of climate and dietary patterns on prevalence of eczema needs further studies.

Abstract
BACKGROUND This study aims to investigate the effects of recombinant human brain natriuretic peptide (rhBNP) on serum enzyme data, cardiac function parameters and cardiovascular events in patients with acute anterior myocardial infarction (MI). METHODS A total of 421 patients with acute anterior or extensive anterior MI were collected from 20 hospitals. These patients were randomly divided into two groups: rhBNP and control groups. Both groups of patients received primary percutaneous coronary intervention (PCI) within the effective time window. In the rhBNP group, rhBNP administration (0.01 µg/kg/min, 48-72 successive hours) was performed as early as possible after hospital admission. Prior to and one or seven days after PCI, serum concentrations of cardiac troponin (cTnT), creatine kinase-MB (CK-MB) and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured. At seven days and 6 months after PCI, left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDd) and stroke volume (SV) were measured using 2D Doppler echocardiography. MACEs that occurred during hospitalization and within 6 months after PCI were recorded. RESULTS At postoperative days one and seven, serum concentrations of cTnT were significantly lower in the rhBNP group than in the control group. At postoperative day one, serum concentrations of CK-MB were significantly lower in the rhBNP group than in the control group. At postoperative day seven, serum concentrations of NT-proBNP were significantly lower in the rhBNP group than in the control group, and LVEF was significantly greater in the rhBNP group than in the control group. At postoperative 6 months, LVEDd was significantly lower in the rhBNP group compared with the control group. In addition, SV and LVEF were significantly greater in the rhBNP group than in the control group. By postoperative month 6, the incidence of composite cardiovascular events (16.0% vs. 26.0%, P=0.012), cardiac death (7.0% vs.13.5%, P=0.030), and particularly cardiac death + re-hospitalization for congestive heart failure (13.1% vs. 25.5%, P=0.001) were significantly lower in the rhBNP group than in the control group. CONCLUSIONS Early intravenous rhBNP administration after PCI significantly lowered the serum concentrations of cTnT and NT-proBNP, increased LVEDd, SV and LVEF, and reduced MACEs, including cardiac death, in patients with acute anterior MI undergoing PCI.

Abstract
In this paper, an injectable micellar supramolecular hydrogel composed of α-cyclodextrin (α-CD) and monomethoxy poly(ethylene glycol)-b-poly(ε-caplactone) (MPEG5000-PCL5000) micelles was developed by a simple method for hydrophobic anticancer drug delivery. By mixing α-CD aqueous solution and MPEG5000-PCL5000 micelles, an injectable micellar supramolecular hydrogel could be formed under mild condition due to the inclusion complexation between α-CD and MPEG segment of MPEG5000-PCL5000 micelles. The resultant supramolecular hydrogel was thereafter characterized by X-ray diffraction (XRD) and Scanning electron microscopy (SEM). The effect of α-CD amount on the gelation time, mechanical strength and thixotropic property was studied by a rheometer. Payload of hydrophobic paclitaxel (PTX) to supramolecular hydrogel was achieved by encapsulation of PTX into MPEG5000-PCL5000 micelles prior mixing with α-CD aqueous solution. In vitro release study showed that the release behavior of PTX from hydrogel could be modulated by change the α-CD amount in hydrogel. Furthermore, such supramolecular hydrogel could enhance the biological activity of encapsulated PTX compared to free PTX, as indicated by in vitro cytotoxicity assay. All these results indicated that the developed micellar supramolecular hydrogel might be a promising injectable drug delivery system for anticancer therapy.

Abstract
OBJECTIVE To observe the efficacy and safety of bivalirudin use in Chinese patients with coronary heart disease (CHD) during the peri-percutaneous coronary intervention(PCI) period. METHODS A total of 3 271 patients who underwent PCI and received periprocedural bivalirudin treatment between July 2013 and October 2015 from 88 centers of China were involved in this study. The primary outcome was 30-day net adverse clinical events (NACE a composite of major adverse cardiac or cerebral events (MACE, all-cause death, reinfarction, urgent target vessel revascularization, or stroke) or bleeding), the secondary outcome was stent thrombosis at 30 days. RESULTS The mean age of enrolled patients was (65.12±12.44) years old, 27.4%(889/3 244) of them were female. Percent of stable coronary disease (SCD), non-ST segment elevation acute coronary syndrome (NSTE-ACS) and ST elevation myocardial infarction (STEMI) was 5.0%(162/3 248), 44.6%(1 450/3 248) and 50.4%(1 636/3 248) respectively. Radial access was performed in 89.5% (2 879/3 271) patients, and 9.7% (316/3 271) and 34.1% (1 115/3 271) patients also received ticagrelor and tirofiban medication. 69.3% (2 266/3 271) patients received post-procedural bivalirudin infusion, in which 46.3% (1 050/2 266) was treated at PCI-does, with a median duration of 2.5(1.0, 4.0) h. During the 30-day follow-up, NACE occurred in 3.45% (103/2 988) patients, the incidence of MACE, death was 2.17% (65/2 994) and 1.03% (31/3 017), respectively and bleeding events were recorded in 1.37% (41/2 996) patients. Four cases (0.13%) of stent thrombosis (3 acute stent thrombosis) were recorded. CONCLUSION Peri-PCI Bivalirudin use is safe and related with low bleeding risk in Chinese CHD patients.

Abstract
Despite the clinical success of tamoxifen, its resistance remains a major challenge in breast cancer. Here we show that Aurora-A determines tamoxifen sensitivity by regulation of oestrogen receptor (ER)α. Ectopic expression of Aurora-A decreases and depletion of Aurora-A enhances tamoxifen sensitivity in ERα-positive breast cancer. Elevated Aurora-A was significantly associated with the recurrence of ERα-positive tumours. Notably, Aurora-A inhibitor MLN8237, which is currently in clinical trial, synergizes with tamoxifen and overcomes tamoxifen resistance. Furthermore, Aurora-A interacts with and phosphorylates ERα on serine-167 and -305, leading to increase in ERα DNA-binding and transcriptional activity. Elevated levels of Aurora-A are significantly associated with disease-free survival in ERα-positive but not ERα-negative breast cancers. These data suggest that Aurora-A has a pivotal role in tamoxifen resistance and ERα is a bona fide substrate of Aurora-A. Thus, Aurora-A represents a prognostic marker in ERα-positive tumour and a critical therapeutic target in tamoxifen-resistant breast cancer, and Aurora-A inhibitor could be used as either an independent or concurrent agent in tamoxifen-resistant tumour.

Abstract
Background This study investigated infection status and distribution of human cytomegalovirus (HCMV) serum markers in hospitalized children from the Wenzhou region. Methods This survey was performed on 10,147 hospitalized children from birth to 14 years of age in Southeastern China (Wenzhou region) from March 2010 to March 2013. IgM and IgG antibodies to HCMV were quantitatively detected by chemiluminescence immunoassay (CLIA). HCMV IgM or IgG detection rates, concentration, and distribution in various age groups were retrospectively analyzed. Results In this study of hospitalized children, the overall rates of HCMV IgM+ and IgG+ were 10.8% (1,099/10,147) and 83.0% (8,425/10,147), respectively. The lowest HCMV IgM+ rate (1.0%, P < 0.001) was observed in the group of patients <28 days of age whereas the highest HCMV IgM+ rate (19.9%, P < 0.001) occurred in the 28 days ~ 5 months old group. However, the concentrations of HCMV specific IgM in all age groups were not significantly different (P > 0.05). The HCMV IgG+ rate was highest in the <28 days group (98.1%, P < 0.001). The 28 days ~ 5 months old group had the lowest HCMV specific IgG concentrations (median, 133.9 AU/mL, P < 0.001). Among 1,099 HCMV IgM+ children, 405 (36.9%) were diagnosed with respiratory infections which pneumonia accounted for 18.2% (200/1,099) of the total population. However, children with respiratory infections had the lowest HCMV IgG concentrations (median, 161.1 AU/mL, P < 0.05). Conclusions HCMV specific antibody responses are very common in hospitalized children with respiratory infection in Wenzhou region. Protection against HCMV airway infection needs greater emphasis and further studies will be helpful to reveal the role of HCMV in children respiratory disease.

Abstract
OBJECTIVE Explore the relationship between the HLA-G 14bp insertion/deletion polymorphism and the infection of Enterovirus 71 (EV71) for children. METHODS We genotyped HLA-G 14bp insertion/deletion polymorphism of 125 severe HFMD children infected with EV71 and 133 normal controls by PCR-PAGE;detected the plasma sHLA-G level of 66 heavy type and 15 critical type and 133 normal controls by ELISA. RESULTS Frequencies of the genotype 14 bp - / - ,14 bp + / - and 14 bp + / + were 49.6% , 42.4% and 8.0% for the severe HFMD children infected with EV71, and 34.6%, 48.9% and 16.5% for the normal controls, respectively. A significant difference was observed for the frequencies of the HLA-G 14bp genotype between the two groups(chi2 = 7.850, P = 0.020). And for the allele frequencies. The plasma sHLA-G levels in heavy type were dramatically higher than that in normal controls (Z = -9.692, P = 0.000). The plasma sHLA-G levels in children with critical HFMD were dramatically higher than that with heavy type (Z = -2.420, P = 0.016). CONCLUSION There was a relationship between the HLA-G 14 bp insertion/deletion polymorphism and the susceptibility to the severe HFMD children infected with EV71 and the plasma sHLA-G might be considered as a index for auxiliary diagnosis the severe HFMD infected with EV71.

Abstract
Using molecular dynamics simulations, disorder trapping associated with solidification is studied for the (100), (110), and (111) growth directions in the B2 NiAl ordered alloy compound. At the high interface velocities studied we observe pronounced disorder and defect trapping, i.e., the formation of antisite defects and vacancies in the crystal at higher than equilibrium concentrations upon rapid solidification. The vacancies are located primarily on the Ni sublattice and the majority of antisite defects are Ni atoms on the Al sublattice, while the concentration of Al on the Ni sublattice is negligibly small. The defect concentration is found to increase in an approximately linear relationship with increasing the interface velocity. Further there is no significant anisotropy in the defect concentrations for different interface orientations. Our results suggest that the currently available models of disorder trapping should be extended to include both antisite defects and vacancies.

Abstract
Human leukocyte antigen-G (HLA-G) has been hypothesized to be associated with the pathogenesis of asthma; however, results remain controversial. Furthermore, HLA-G expression could be modulated by the HLA-G 14-bp insertion (+)/deletion (-) polymorphism and by interleukin-10. In this study, the 14-bp polymorphism in exon 8 of the HLA-G gene, plasma soluble HLA-G, and interleukin-10 (IL-10) levels in untreated atopic asthmatic children, and in a group of age-, gender-, and ethnicity-matched normal controls were analyzed. Data showed that HLA-G 14-bp +/- polymorphism was not significant difference between the asthmatic patients and normal controls. Plasma soluble human leukocyte antigen (sHLA)-G in atopic asthma patients (n = 72; median, 179.28 U/ml) was dramatically higher compared with that of the normal controls (n = 76; median, 35.23 U/ml; p < 0.001). Receiver operating characteristic (ROC) curve analysis showed that the area under ROC curve for sHLA-G was 0.986 (p < 0.001) in atopic asthma patients versus normal controls. IL-10 levels in the asthmatic children (n = 50; median, 5.02 pg/ml) was significantly lower than that of the normal controls (n = 48; median, 12.82 pg/ml; p < 0.001). Both HLA-G 14-bp polymorphism and IL-10 levels were unrelated to plasma sHLA-G concentration in both groups. Our findings indicated that the HLA-G 14-bp polymorphism was not a risk factor, but that sHLA-G might be considered as a biomarker for the atopic asthmatic patients. Dramatically increased sHLA-G with decreased IL-10 levels may have implications in the pathogenesis of atopic asthma.

Abstract
Lignocelluloses prepared from woody tea stalk, pine sawdust and sugarcane bagasse were used as adsorbents to isolate decaffeinated catechins from tea extracts and compared with synthetic macroporous resin HPD 600. HPD 600 had the highest adsorption capacity to catechins, followed by tea stalk lignocellulose while lignocelluloses of pine sawdust and bagasse the least. Tea stalk lignocellulose absorbed preferentially tea catechins and showed a good selectivity. HPD 600 absorbed caffeine and tea catechins simultaneously. The kinetics data of tea stalk lignocellulose showed a good fit with the Langmuir isotherm model. It is considered that tea stalk lignocellulose is an alternative low-cost adsorbent for preparing decaffeinated tea catechins.

Abstract
Bulk segregant analysis (BSA), randomly amplified polymorphic DNA (RAPD) and sequence characterized amplified region (SCAR) methods were used to tag the downy mildew-resistant genes of grape with molecular markers. Parents and their 60 individuals of an F1 progeny resulting from a cross 88-110 between 83-4-96 (Vitis quinquangularis, downy mildew-resistant) and Muscat Rose (V. vinifera, downy mildew-susceptible), three F2 progenies resulting from three crosses of self-cross and inter-cross of 88-110 F1 seedlings, as well as another interspecific F1 hybrids of 88-84 cross [Xun-3 (V. quinquangularis, downy mildew-resistant) x Ugni Blanc (V. vinifera, downy mildew-susceptible)] and the wild grapes native to China were used for the study. Among 280 Operon primers, 160 gave distinct band patterns. One RAPD marker OPO06-1500 was tightly linked to a major gene resistant to Plasmopara viticola (RPv-1). Based on Mapmaker software analysis, the map distance between RPv-1 and OPO06-1500 was 1.7 cM. Marker OPO06-1500 was cloned and sequenced. According to the sequence, two specific primers were designed to amplify all plant materials. RAPD marker was converted into SCAR marker (SCO06-1500). One distinct single band only in resistant plants was amplified, whose size was the same as that of the RAPD marker. The SCAR marker's popularity was confirmed, and it could be used for the identification of hybrid resistant to P. viticola and will be potentially useful in the development of new resistant grape cultivars.

Abstract
Under strict quality control, the authors investigated the levels of PbB among 270 women from early pregnancy to delivery and their infants. The mean PbB levels of the first three months of pregnancy and delivery is 45.0 microg/L and 64.8 microg/L respectively. Analysis shows an increase of mean PbB level in the period of gestation, and a significant increase in the last three months. The mean PbB level of umbilical cord is 51.9 microg/L (10.4% umbilical cord PbB > 100 microg/L). The mean PbB level of infants increases with the months, it increases significantly after six months. Regression analysis confirmed the positive correlation between the PbB levels of first three and second three months of gestation, the PbB of delivery and umbilical cord, the PbB of umbilical coral and infants. The correlation coefficient of the PbB level of delivery and umbilical cord, the PbB level of infants at six months and at twelve months is 0.80 and 0.47 respectively.

Abstract
In vivo activated T cells (CD25+) present in lymph nodes involved by B-non-Hodgkin's lymphomas (B-NHL) were investigated here for their ability to proliferate in vitro. CD25-/CD25+ T cells were isolated using a rosette method with magnetic beads, then the frequency of proliferating T lymphocyte-precursors (PTL-P) in both populations was assessed by limiting dilution experiments, in the presence of IL2, PHA and allogeneic spleen cells as feeders. In a total of 16 cases studied, growing microcultures were observed in all cases for CD25- T cells (mean value of PTL-P frequency: 1/32; range 1/10 - 1/2899) but in 6 cases only for CD25+ T cells (mean value of PTL-P frequency: 1/441; range 1/119 - 1/3736); the absence of any proliferative cultures in the 10 other cases indicated that the number of PTL-P was inferior to 1/12480. These results suggest that the proliferative potential of CD25+ T cells infiltrating lymph nodes involved by B-NHL is paradoxically decreased.

Abstract
More than 2000 blood samples were collected at random from full-time middle school teachers in 9 cities of China and analyzed for lead concentration with strict quality assurance procedures. Questionnaries about the smoking habits, alcohol consumption, residence condition, and fuel used at home were filled out by each person, and information about traffic, and lead concentration in different areas of the environment was also collected as far as possible. The result showed that the geometric mean of blood lead levels of teachers in different cities was ranging between 59-82 μg l(-1) among them the lowest levels were found in Nanjing and the highest in Shanghai. The difference between the lowest and the highest value was only 23 μg l(-1). Comparing with the results of WHO/UNEP and CEC projects. The overall geometric average blood level in China is lower than in all the other countries except Japan. It indicates that the lead pollution in the general environment of China was not as severe as in the participating countries of WHO/UNEP and CEC projects. This may be attributed by the following factors: The less automobile triffic, the larger proportion of non-leaded gasoline used and the less canned food consumption. Factors influencing the lead levels in blood were also analyzed and the 'normal value' (95% upper limit) of blood lead was assessed to be 160 μg l(-1).

Abstract
The histochemical changes of endometrial fibrinolytic activity were observed in rabbits. 1 horn of the uterus was put in IUDs made of different materials (steel, copper, magnet, and EACA-copper). It was found that the endometrial fibrinolytic activity in the experimental horns was significantly higher than the controls, and the effect was the highest with the copper IUD. In the contrasted groups (copper versus steel, copper versus magnet, steel versus magnet), the endometrial fibrinolytic activity induced by the copper IUD was the highest (P0.05), while there was no significant diffeence between that of steel and magnet (P0.05). In the EACA-copper IUD groups, the results were also observed on days 7, 14, and 28 after insertion of the devices. There was no difference in fibrinolytic activity between the experimental horns and the controls in 7 and 14 days groups, but it was significantly higher than the controls in 28 days group. In the contrasted groups of the EACA-copper IUD and copper IUD the endometrial fibrinolytic activity of the former was lower than that of the latter in 7 days group (0.05 P 0.1). This suggests that fibrinolytic activity may be inhibited by EACA, which, however, may be released from IUD at such a rapid rate that it loses its effect in 28 days.
