Abstract
Objective: To investigate the surgical treatment effect and prognostic factors of hilar cholangiocarcinoma. Methods: This is an ambispective cohort study. From August 2005 to December 2022,data of 510 patients who diagnosed with hilar cholangiocarcinoma and underwent surgical resection at the Hepatobiliary Center of the First Affiliated Hospital of Nanjing Medical University were retrospectively collected. In the cohort,there were 324 males and 186 females,with an age of (M (IQR)) 63(13)years (range:25 to 85 years). The liver function at admission was Child-Pugh A (343 cases,67.3%) and Child-Pugh B (167 cases,32.7%). Three hundred and seventy-two(72.9%) patients had jaundice symptoms and the median total bilirubin was 126.3(197.6) μmol/L(range: 5.4 to 722.8 μmol/L) at admission. Two hundred and fourty-seven cases (48.4%) were treated with percutaneous transhepatic cholangial drainage or endoscopic nasobiliary drainage before operation. The median bilirubin level in the drainage group decreased from 186.4 μmol/L to 85.5 μmol/L before operation. Multivariate Logistic regression was used to identify the influencing factors for R0 resection,and Cox regression was used to construct multivariate prediction models for overall survival(OS) and disease-free survival(DFS). Results: Among 510 patients who underwent surgical resection,Bismuth-Corlett type Ⅲ-Ⅳ patients accounted for 71.8%,among which 86.1% (315/366) underwent hemi-hepatectomy,while 81.9% (118/144) underwent extrahepatic biliary duct resection alone in Bismuch-Corlett type Ⅰ-Ⅱ patients. The median OS time was 22.8 months, and the OS rates at 1-,3-,5-and 10-year were 72.2%,35.6%,24.8% and 11.0%,respectively. The median DFS time was 15.2 months,and the DFS rates was 66.0%,32.4%,20.9% and 11.0%,respectively. The R0 resection rate was 64.5% (329/510), and the OS rates of patients with R0 resection at 1-,3-,5-and 10-year were 82.5%, 48.6%, 34.4%, 15.2%,respectively. The morbidity of Clavien-Dindo grade Ⅲ-Ⅴ complications was 26.1%(133/510) and the 30-day mortality was 4.3% (22/510). Multivariate Logistic regression indicated that Bismuth-Corlett type Ⅰ-Ⅲ (P=0.009), hemi-hepatectomy and extended resection (P=0.001),T1 and T2 patients without vascular invasion (T2 vs. T1:OR=1.43 (0.61-3.35),P=0.413;T3 vs. T1:OR=2.57 (1.03-6.41), P=0.010;T4 vs. T1, OR=3.77 (1.37-10.38), P<0.01) were more likely to obtain R0 resection. Preoperative bilirubin,Child-Pugh grade,tumor size,surgical margin,T stage,N stage,nerve infiltration and Edmondson grade were independent prognostic factors for OS and DFS of hilar cholangiocarcinoma patients without distant metastasis. Conclusions: Radical surgical resection is necessary to prolong the long-term survival of hilar cholangiocarcinoma patients. Hemi-hepatectomy and extended resection,regional lymph node dissection and combined vascular resection if necessary,can improve R0 resection rate.

Abstract
Paragonimiasis is a common zoonotic parasitic disease. The retinoic acid-inducible gene I (RIG-I) signaling is very important for the host to recognize invading pathogens (especially viruses and bacteria). However, the role of RIG-I signaling in the early stages of P. proliferus infection remains unclear. Therefore, in this study, Sprague-Dawley (SD) rat models with lung damage caused by P. proliferus were established. Experimental methods including Enzyme-linked Immuno Sorbent Assay (ELISA), real-time fluorescent quantitative polymerase chain reaction (PCR), western blotting, and hematoxylin and eosin (HE) staining were used to explore the mechanisms of lung injury caused by P. proliferus. As a result, the expression of the mRNA and proteins of RIG-I signal-related key target molecules, including RIG-I, tumor necrosis factor (TNF) receptor associated factor 6 (TRAF6), interferon regulatory Factor 7 (IRF7), IPS-1, and downstream C-X-C chemokine ligand 10 (CXCL10), were significantly up-regulated immediately after infection, peaked at 3 or 7 days, and showed a downward trend on after 14 days. The levels of pro-inflammatory cytokines interleukin-1 (IL-1), interferon (IFN)-α, -β, and -γ, which represent type 1 immune response, gradually increased and reached a peak by 14 days, which was consistent with the changes in the degree of inflammatory damage observed under HE staining of lung tissues. In conclusion, RIG-I signaling is activated in the early stage (before 14 days) of P. proliferus infection, it is inferred that the lung injury of the host may be related to the activation of RIG-I like signaling to induce type I immune response.

Abstract
Objective: To investigate the clinicopathological features, classification, and genetic characteristics of common lymphatic malformation (CLM) in superficial soft tissue. Methods: A retrospective study of 110 patients with the diagnosis of CLM at the Henan Province People's Hospital, China from August 2019 to August 2022 was performed. The clinicopathological features, relevant immunohistochemical (IHC) staining results, and fluorescence quantitative PCR of PIK3CA mutation were analyzed, and patients were followed up. Results: Among the 110 CLM patients, there were 53 males and 57 females; 65 cases (65/110, 59.1%) were first detected when the patients were≤2 years old. The most common location was the head and neck in 41 cases (41/110, 37.3%). Clinically, 102 cases (102/110, 92.7%) were solitary, 83 cases (83/110, 75.5%) were skin-colored, 69 cases (69/110, 62.7%) had indistinct borders, and 10 cases (10/110, 9.1%) had diffuse and severe macroscopic manifestations. There were 52 macrocystic type (52/110, 47.3%), 23 microcystic type (23/110, 20.9%), and 35 combined type (35/110, 31.8%). The macrocystic CLM presented as soft, translucent masses with large cystic cavities on the cut surface, and histologically they were composed of large, irregularly dilated channels that were thicker with irregular smooth muscle and lymphocytic infiltration. Microcystic CLM showed wartlike projections or translucent blisters on the skin, with small honeycomb structures on the cut surface, and histologically consisted of round or angular dilated small lymphatic vessels with little or no smooth muscle. The combined CLM had both macrocystic and microcystic morphologies. IHC staining showed that the lymphatic endothelial cells were positive for LYVE-1, D2-40, PROX1, CD31, and VEGFR3 but negative for CD34; in the macrocystic and combined CLM vessel walls were positive for SMA. Eight of 13 CLM had PIK3CA mutation. All patients were followed up, and 24 (24/110, 21.8%) had relapses, which more frequently occurred in combined type, followed by microcystic type. Conclusions: CLM is a congenital vascular malformation composed of dilated, abnormal lymphatic channels, with PIK3CA mutation. There are significant differences in clinicopathological characteristics among the different types. Since microcystic and combined CLM are prone to recurrence, accurate pathological subtyping is necessary to guide treatment and to predict prognosis.

Abstract
Objective: To investigate the correlation between the osseous structure of temporomandibular joint (TMJ) and three different status of anterior disc location, so that it could guide the clinical diagnosis further. Methods: Fifty-two patients [46 females and 6 males, with an age of (27.8±8.3) years] who treated with MRI and cone beam CT, were recruited from the Temporomandibular Joint Specialist Clinic, The First Affiliated Hospital of Xinjiang Medical University, between March 2018 to December 2021. According to the radiographic findings of the level of anterior disc displacement (ADD) in TMJ, patients were divided into three groups: normal articular disc position (NADP, n=28 TMJs), anterior disc displacement with reduction (ADDWR, n=28 TMJs), and anterior disc displacement without reduction (ADDWoR, n=28 TMJs). In the light of the reconstructed three-dimensional model, ten representative morphological parameters including condylar volume (CV), condylar superficial area (CSA), fossa volume (FV), fossa superficial area (FSA), the proportion of the condylar volume in the articular fossa (CV%), the proportion of the condylar superficial area in the articular fossa (CSA%), superior joint space (SJS), anterior joint space (AJS), posterior joint space (PJS), and medial joint space (MJS), were measured respectively under one-way analysis of variance (ANOVA), Kruskal-Wallis Htest and receiver operator characteristic curve(ROC curve) analyses. Results: CV and CSA values varied significantly in the pathological progression from normal location to irreversible anterior displacement in TMJ. For CV value, NADP group [(1 834.90±667.67) mm3]>ADDWR group [(1 747.34±369.42) mm3]>ADDWoR group [(1 256.29±418.27) mm3] [t=4.31, P(NADP-ADDWoR)<0.001; t=3.66, P(ADDWR-ADDWoR)<0.001], for CSA value, NADP group [(859.27±216.01) mm2]>ADDWR group [(838.23±118.82) mm2]>ADDWoR group [(669.14±150.26) mm2] [t=4.27, P(NADP-ADDWoR)<0.001; t=3.80, P(ADDWR-ADDWoR)<0.001]. The difference of SJS value in NADP group [(2.22±0.88) mm], ADDWR group [(1.94±0.64) mm] and ADDWoR group [(1.45±0.57) mm], was statistically significant [t=4.11, P(NADP-ADDWoR)<0.001; t=2.63, P(ADDWR-ADDWoR)=0.010]. The results of MJS in NADP group [(5.03±1.41) mm], ADDWR group [(3.86±1.32) mm], and ADDWoR group [(4.91±1.65) mm] were significantly different [t=3.00, P(NADP-ADDWR)=0.004; t=2.63, P(ADDWR-ADDWoR)=0.009]. As calculated by the ROC curve analysis, CV, CSA and SJS showed that (AUCCV=0.77, AUCCSA=0.76; AUCSJS=0.76) for the NADP and ADDWoR groups, and (AUCCV=0.80; AUCCSA=0.80; AUCSJS=0.72) for the ADDWR and ADDWoR groups. While the diagnostic accuracy of MJS for the comparison in NADP versus ADDWR and ADDWR versus ADDWoR was respectively AUC(NADP-ADDWR)=0.73, and AUC(ADDWR-ADDWoR)=0.69. Conclusions: CV, CSA, SJS, and MJS were significantly associated with the different disc displacement status, and the condyle in TMJ ADD exhibited three-dimensionally altered dimensions. They could be considered as promising biometric markers to diagnose the ADD status.

Abstract
To explore the clinical and pathological characteristics as well as therapies and prognosis of gray zone lymphoma (GZL). The clinical data of 10 GZL patients admitted to the First Affiliated Hospital of Soochow University from December 2016 to December 2022 were retrospectively collected. The clinical and pathological characteristics, therapies and prognosis were analyzed. The cut-off time for follow-up visits was December 31, 2022, and the median time for follow-up visits [M(Q1, Q3)] was 40.0 (28.3, 59.8) months. Treatment efficacy was divided into complete remission (CR), partial remission (PR), stable disease (SD) and progressive disease (PD). There were 6 males and 4 females, with a median age [M(Q1, Q3)] of 33.5 (27.3-39.5) years. Among them, 8 patients had mediastinal (thymus) involvement and 7 patients were accompanied with extranodal involvement. According to Ann Arbor staging, 1 case was in the limited stage and 9 cases were in the progressive stage. The immunophenotypes of 4 patients were strong expression of CD20, expression of CD30, and no expression of CD15. The immunophenotypes of 6 patients were unequal expression of CD20 and strong expression of CD30 and CD15. One patient received classical hodgkin lymphoma(cHL)-like immunochemotherapy and only achieved PR, and then received enhanced diffuse large b-cell lymphoma (DLBCL)-like immunochemotherapy to achieve CR. Five patients received enhanced DLBCL-like immunochemotherapy for induction therapy and achieved CR. All 4 patients who did not achieve CR achieved CR after receiving second-line or third-line salvage therapy. All patients were given autologous stem cell transplantation (ASCT) for consolidation therapy. One patient relapsed and died during the follow-up visit in the 33rd month, and the remaining patients currently maintained a state of sustained remission. It is found that GZL mostly occurs in young patients, mediastinal involvement is common, and diagnosis relies on pathological morphology and immunophenotype. GZL may be more sensitive to DLBCL-like intensive immune regimens. Sequential ASCT for consolidation can reduce the risk of relapse.

Abstract
Objective: To investigate the prevalence of Helicobacter pylori infection among family members, and analyze associated risk factors. Methods: The current investigation was a cross-sectional study. The Qinghai region was stratified into urban areas, agricultural areas, and pastoral areas. The urban areas of Xining City, the agricultural areas of Haidong City, and the pastoral areas of Haibei Tibetan Autonomous Prefecture were selected. A total of 396 resident families (1 131 people) who underwent health checkups from 2021 to 2022 in the above areas were included in the survey study. Questionnaires were administered and H. pylori infection was detected using the 13C-urea breath test. Numerical data were expressed as cases and percentages, and the Chi-square test was used to compare differences in H. pylori infection rates in the populations and families in each group. Multifactorial logistic regression was used to analyze risk factors for H. pylori infection, and P<0.05 was considered statistically significant. Results: The prevalence of H. pylori infection in Qinghai province was 52.8% (597/1 131) and the prevalence of H. pylori infection in households was 80.6% (319/396). In H. pylori-positive households with at least 1 infected spouse, 40.4% (36/89) had only 1 infected spouse, and in 59.6% (53/89) both spouses were infected. In analysis of children infected by parents with H. pylori, 20.0% (9/45) of households had fathers and children infected, 48.9% (22/45) had mothers and children infected, and 31.1% (14/45) had both parents and children infected. In univariate analysis there was a statistically significant difference in the overall comparison of H. pylori infection rates among families with different numbers of people living together (χ2=11.12, P=0.004), and between-group comparisons suggested that H. pylori infection rates were higher in families with 4 or 5 people and more than 5 people living together than in families with 2 or 3 people living together. The H. pylori infection rate was higher in families that did not use serving chopsticks and spoons during family meals than in families that did use serving chopsticks and spoons (χ2=6.12, P=0.013). In multifactorial logistic regression analyses the number of people living together in a family and whether or not serving chopsticks and spoons were used at family meals were associated with H. pylori infection (P<0.05). Conclusion: The H. pylori infection rate in families in Qinghai Province is high, and there is a clear association with family aggregation. It is more common for both members of a couple to be infected, and H. pylori infection of a mother has a greater effect on the children's infection status than H. pylori infection of a father. The infection rate of H. pylori was lower in families that used serving chopsticks and spoons during dinner gatherings, and the fewer the number of people living together in the family, the lower the H. pylori infection rate.

Abstract
Objective: To investigate the clinicopathological features of glomuvenous malformation (GVM). Methods: Thirty-one cases of GVM diagnosed at the Henan Provincial People's Hospital from January 2011 to December 2021 were collected. Their clinical and pathological features were analyzed. The expression of relevant markers was examined using immunohistochemistry. The patients were also followed up. Results: There were 16 males and 15 females in this study, with an average age of 11 years (range, 1-52 years). The locations of the disease included 13 cases in the limbs (8 cases in the upper limbs, 5 cases in the lower limbs), 9 cases in the trunks, and 9 cases in the foot (toes or subungual area). Twenty-seven of the cases were solitary and 4 were multifocal. The lesions were characterized by blue-purple papules or plaques on the skin surface, which grew slowly. The lumps became larger and appeared to be conspicuous. Microscopically, GVM mainly involved the dermis and subcutaneous tissue, with an overall ill-defined border. There were scattered or clustered irregular dilated vein-like lumens, with thin walls and various sizes. A single or multiple layers of relatively uniform cubic/glomus cells were present at the abnormal wall, with scattered small nests of the glomus cells. The endothelial cells in the wall of abnormal lumen were flat or absent. Immunohistochemistry showed that glomus cells strongly expressed SMA, h-caldesmon, and collagen IV. Malformed vascular endothelial cells expressed CD31, CD34 and ERG. No postoperative recurrence was found in the 12 cases. Conclusions: GVM is an uncommon type of simple venous malformation in the superficial soft tissue and different from the classical glomus tumor. Morphologically, one or more layers of glomus cells grow around the dilated venous malformation-like lumen, which can be combined with common venous malformations.

Abstract
OBJECTIVE Efforts have been made to reduce epidemiological indicators of osteoradionecrosis in patients with head and neck cancer over recent years. This umbrella review aims to synthesize the information of the systematic reviews/meta-analyses investigating the effect of radiotherapy in patients with head and neck cancer on the frequency of osteoradionecrosis and to identify and analyze the gaps in current scientific literature. MATERIAL AND METHODS A systematic review of systematic reviews with and without meta-analysis of intervention studies was conducted. Qualitative analysis of the reviews and their quality evaluation were performed. RESULTS A total of 152 articles were obtained, and ten of them were selected for the final analysis, where six were systematic reviews and four were meta-analysis. According to the guide Assessing the Methodological Quality of Systematic Reviews (Amstar), eight articles included were of high quality and two of medium quality. These descriptive systematic reviews/meta-analyses included a total of 25 randomized clinical trials, showing that radiotherapy has positive effects on the frequency of osteoradionecrosis. Even though a reduction in the incidence of osteoradionecrosis was observed back in the history, in systematic reviews with meta-analysis, overall effect estimators were not significant. CONCLUSIONS Differential findings are not enough to demonstrate that there is a significant reduction in the frequency of osteoradionecrosis in patients with head and neck cancer treated by radiation. Possible explanations are related to factors such as the type of studies analyzed, indicator of irradiated complication considered, and specific variables included in the analysis. Many systematic reviews did not address publication bias and did identify gaps in knowledge that require further clarification.

Abstract
Objective: To assess the efficacy and safety of polymyxin B in neutropenic patients with hematologic disorders who had refractory gram-negative bacterial bloodstream infection. Methods: From August 2021 to July 2022, we retrospectively analyzed neutropenic patients with refractory gram-negative bacterial bloodstream infection who were treated with polymyxin B in the Department of Hematology of the First Affiliated Hospital of the Soochow University between August 2021 to July 2022. The cumulative response rate was then computed. Results: The study included 27 neutropenic patients with refractory gram-negative bacterial bloodstream infections. Polymyxin B therapy was effective in 22 of 27 patients. The median time between the onset of fever and the delivery of polymyxin B was 3 days [interquartile range (IQR) : 2-5]. The median duration of polymyxin B treatment was 7 days (IQR: 5-11). Polymyxin B therapy had a median antipyretic time of 37 h (IQR: 32-70). The incidence of acute renal dysfunction was 14.8% (four out of 27 cases), all classified as "injury" according to RIFLE criteria. The incidence of hyperpigmentation was 59.3%. Conclusion: Polymyxin B is a viable treatment option for granulocytopenia patients with refractory gram-negative bacterial bloodstream infections.

Abstract
Objective: To investigate the plasma levels of thrombin activatable fibrinolysis inhibitor (TAFI), plasminogen activator inhibitor-1 (PAI-1) and tissue-type plasminogen activator (t-PA) in patients with systemic lupus erythematosus (SLE), and their relationship with deep venous thrombosis of the lower limbs. Methods: A case-control study was conducted to retrospectively select 32 SLE patients with deep venous thrombosis of the lower extremities (thrombus group) admitted to Liaocheng People's Hospital in Shandong Province from June 2018 to June 2021, including 4 males and 28 females, with a mean age of (49.7±5.5) years. Meanwhile, 64 SLE patients without deep venous thrombosis of the lower extremities (control group) were also selected, including 11 males and 53 females, with a mean age of (50.8±5.5) years. The plasma levels of TAFI, PAI-1 and t-PA of the two groups were compared. A logistic regression model was used to analyze the correlation of TAFI, PAI-1 and t-PA with SLE in patients. Results: The plasma levels of TAFI, PAI-1 and t-PA were (32.77±5.17) mg/L, (29.43±5.51) μg/L and (6.58±1.40) μg/L in the thrombotic group, while the plasma levels of TAFI, PAI-1 and t-PA in the control group were (23.56±4.40) mg/L, (19.00±4.40) μg/L and (9.40±2.23) μg/L. The levels of TAFI and PAI-1 in the thrombotic group were higher than those in the control group, while the level of t-PA was lower than that in the control group (all P<0.05). The results of logistic regression model showed that higher TAFI levels (OR=1.75, 95%CI: 1.05-2.90, P=0.043), higher PAI-1 levels (OR=1.85, 95%CI: 1.04-3.29, P=0.046), and lower t-PA levels (OR=0.72, 95%CI: 0.52-0.99, P=0.048) were related factors for the occurrence of deep venous thrombosis of the lower limbs in SLE patients. Conclusion: The plasma levels of TAFI and PAI-1 in SLE patients with deep venous thrombosis of the lower extremities increase, while the t-PA level decreases, which are related factors for the occurrence of deep venous thrombosis of the lower extremities in SLE patients.

Abstract
To examine the association between human leukocyte antigen (HLA) and nevirapine (NVP)- and efavirenz (EFV)-induced cutaneous adverse reactions in human immunodeficiency virus (HIV) patients, we conducted a case-control study at our center consisting of 96 patients. Patients were further assigned based on the occurrence of cutaneous adverse events and the drugs involved. All patients were subjected to next generation sequencing (NGS)-based screening with focus on HLA phenotype, including the presence of HLA-B, HLA-C, and HLA-DRB1. Our data indicated that the HLA-C*01:02:01 allele presence was observed in 47.4% (18/38) of patients in the EFV-hypersensitivity group compared with 18.9% (7/30) in the control group [odds ratio (OR) = 5.837; 95% confidence interval (CI) = 1.727-19.722, p = .005]. In contrast, the occurrence of HLA-DRB1*08:03 was found to be significantly lower in the EFV-hypersensitivity group (4/38, 10.5%) compared with the corresponding control group (12/37, 32.4%) (OR = 0.148; 95% CI = 0.035-0.625, p = .009). In addition, the HLA-DRB1*04:05:01 antigen was expressed more frequently in the NVP-hypersensitivity group (23.8%, 5/21) compared with the control group (10.8%, 4/37) (OR = 7; 95% CI = 1.265-38.793, p = .026). Our data not only revealed a significant association between HLA-C*01:02:01 and EFV-induced cutaneous adverse reactions but may also shed light on defining the treatment for Chinese HIV patients.

Abstract
Objective: To determine the effect of tumor metastasis-associated gene 1 (MTA1) on the sensitivity of HeLa cells to radiotherapy, and to clarify its molecular mechanism. Methods: The transcriptome differences between MTA1 knocked down Hela cells and control cells were analyzed, and the differentially expressed genes (DEGs) was used to perform Gene-Set Enrichment Analysis (GSEA) and Gene Ontology (GO) cluster analysis. Flow cytometry was used to detect apoptosis in MTA1-overexpressed HeLa cells and control cells before and after 10 Gy X-ray irradiation. Cloning formation assay and real-time cellular analysis (RTCA) were used to monitor the cell proliferation before and after 2 Gy X-ray irradiation. To dissect the underlying molecular mechanisms of MTA1 affecting the sensitivity of radiotherapy, the proteins encoded by the DEGs were selected to construct a protein-protein interaction network, the expression of γ-H2AX was detected by immunofluorescence assay, and the expression levels of γ-H2AX, β-CHK2, PARP and cleaved caspase 3 were measured by western blot. Results: By transcriptome sequencing analysis, we obtained 649 DEGs, of which 402 genes were up-regulated in MTA1 knockdown HeLa cells and 247 genes were down-regulated. GSEA results showed that DEGs associated with MTA1 were significantly enriched in cellular responses to DNA damage repair processes. The results of flow cytometry showed that the apoptosis rate of MTA1 over-expression group (15.67±0.81)% after 10 Gy X-ray irradiation was significantly lower than that of the control group [(40.27±2.73)%, P<0.001]. After 2 Gy X-ray irradiation, the proliferation capacity of HeLa cells overexpressing MTA1 was higher than that of control cells (P=0.024). The numbers of colon in MTA1 over-expression group before and after 2 Gy X-ray irradiation were (176±7) and (137±7) respectively, higher than (134±4) and (75±4) in control HeLa cells (P<0.05). The results of immunofluorescence assay showed that there was no significant expression of γ-H2AX in MTA1 overexpressed and control HeLa cells without X-ray irradiation. Western blot results showed that the expression level of β-CHK2 in MTA1-overexpressing HeLa cells (1.04±0.06) was higher than that in control HeLa cells (0.58±0.25, P=0.036) after 10 Gy X-ray irradiation. The expression levels of γ-H2AX, PARP, and cleaved caspase 3 were 0.52±0.13, 0.52±0.22, and 0.63±0.18, respectively, in HeLa cells overexpressing MTA1, which were lower than 0.87±0.06, 0.78±0.12 and 0.90±0.12 in control cells (P>0.05). Conclusions: This study showed that MTA1 is significantly associated with radiosensitivity in cervical cancer HeLa cells. MTA1 over-expression obviously reduces the sensitivity of cervical cancer cells to X-ray irradiation. Mechanism studies initially indicate that MTA1 reduces the radiosensitivity of cervical cancer cells by inhibiting cleaved caspase 3 to suppress apoptosis and increasing β-CHK2 to promote DNA repair.

Abstract
Objective: To screen core differentially expressed genes of bronchial asthma and conduct bioinformatics analysis. Methods: Macrophage microarray data GSE22528 from asthma patients were downloaded from gene expression database (GEO). The dataset included transcriptome information from 10 human alveolar lavage fluid samples, and five of them were from allergic asthmatic subjects and five from control subjects. Differential expression genes (DEGs) were screened by R 4.0.4 software. Gene ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed to select DEGs using DAVID 6.8 database. Protein interaction network (PPI) was constructed from DEGs encoded proteins using STRING online database. Cytoscape software was used to construct core modules and determine core DEGs. Results: Alveolar lavage fluid samples were all collected from Caucasian Canadians, with age range as (20, 37) and (18, 36) years, respectively, including 3 males for each group. In asthmatic patients, 449 genes were up-regulated and 47 down-regulated. GO analysis showed that the up-regulated genes in asthmatic patients were mainly involved in biological processes such as response to folded proteins, and the molecular function was focused on binding of folded proteins and growth factors. Down-regulated genes were mainly involved in biological processes such as histone deacetylation and ubiquitin-mediated protein degradation, and their molecular functions focused on histone deacetylation activity. KEGG pathway enrichment analysis showed that pathways were mainly enriched by up-regulation genes, involving Hippo signaling pathway, hypertrophic cardiomyopathy, estrogen signaling pathway, arrhythmogenic right ventricular cardiomyopathy, basal cell carcinoma, neuro-activated receptor ligand interaction, dilated cardiomyopathy and adhesion and connection signaling pathways. Two core modules were obtained by PPI analysis, and 14 core DEGs were screened out. They were pro-melanin concentrating hormone (PMCH), prepronociceptin (PNOC), Sphingosinol-1-phosphate receptor 2 (S1PR2), Sphingosinol-1-phosphate receptor 5 (S1PR5), CC-type chemokine ligand 21 (CCL21), Kelch-like protein 25 (KLHL25), ubiquitin binding enzyme E2V2 (UBE2V2), F-box protein 17 (FBXO17), taste receptor type 2 member 3 (TAS2R3), somatostatin receptor 2 (SSTR2), metabolic glutamate receptor 2 (GRM2), Lister E3 ubiquitin protein ligase 1 (LTN1), LIM domain specific protein 7 (LMO7) and ring finger protein 19A gene(RNF19A), in which LTN1 and UBE2V2 were down-regulated and the rest were up-regulated. Conclusion: DEGs was found in macrophages of asthmatic and control individuals. PMCH, PNOC, S1PR2, S1PR5 and CCL21 might be the core genes in the pathological process of asthma.

Abstract
Objective: To explore the effect of human bone marrow mesenchymal stem cells(MSC) on the steroid resistance of human airway epithelial cells. Methods: Ovalbumin (OVA)/lipopolysaccharide (LPS) were used to construct steroid resistant BEAS-2B cells, which were then co-cultured with MSC. Groups were set as follows: blank group, model group, Glucocorticoid group, MSC group, MSC+Glucocorticoid group (MSC+bud group). The expression of interleukin (IL)-8 in the cell supernatant was detected by enzyme-linked immunosorbent assay (ELISA); the expression of reactive oxygen species (ROS) in the cells was detected by flow cytometry; the expression of glucocorticoid receptor α (GRα) and histone deacetylase 2 (HDAC2) protein in the cell was detected by Western blotting; and the expression of GRα and HDAC2 mRNA was detected by reverse transcription-polymerase chain reaction (RTPCR). Results: The expression level of IL-8 in the MSC group was significantly lower than that in the Glucocorticoid group (31.7±0.7 vs. 49.8±3.6, P<0.01). The expression of ROS in the MSC group was significantly lower than that in the Glucocorticoid group (2754±154 vs.4624±228, P<0.05). The expression level of HDAC2 mRNA in the MSC group was significantly higher than that in the Glucocorticoid group(1.749±0.005 vs. 1.283±0.098, P<0.05). The expression level of GRα mRNA in the MSC group was significantly higher than that in the Glucocorticoid group (1.623±0.079 vs.1.047±0.220, P<0.01). The expression of HDAC2 protein in the MSC group was significantly higher than that in the Glucocorticoid group (1.067±0.100 vs. 0.620±0.083, P<0.01). The expression of GRα protein in the MSC group was significantly higher than that in the Glucocorticoid group (0.834±0.053 vs. 0.579±0.017, P<0.01). ROS was positively correlated with the IL-8 expression (r=0.796, P<0.01) and negatively correlated with the HDAC2 and GRα mRNA expression (r=-0.893 3, P<0.01; r=0.931 4, P<0.01, respectively), as well as the HDAC2 and GRα Protein expression (r=-0.929 5, P<0.01;r=-0.864 3, P<0.01, respectively). Conclusions: Human MSC can improve steroid resistance of airway epithelial cells in an exocrine manner. The mechanism may be related to the down-regulation of ROS and up-regulation of HDAC2, which lead to GRα overexpression. In addition, MSC may improve the steroid resistance by reducing the expression of IL-8.

When the cells were treated with 2, 4, 6, 8 Gy irradiation, the cell survival scores of the si-TPT1-AS1 group were 0.280±0.040, 0.069±0.011, 0.020±0.003 and 0.005±0.001, respectively, lower than 0.648±0.070, 0.348±0.080, 0.130±0.020 and 0.060±0.009 of the si-NC group (P<0.05), the radiosensitization ratio of the si-TPT1-AS1 group was 1.672. The number of cell migration and invasion in the si-TPT1-AS1 group were (50.00±4.36) and (44.00±4.03), respectively, which were lower than (109.00±8.68) and (94.00±7.49) in the si-NC group (P<0.05), the cell absorbance (A) values at 24, 48 and 72 hours were 0.28±0.03, 0.43±0.04 and 0.68±0.07, respectively, lower than 0.46±0.04, 0.87±0.08 and 1.35±0.13 of the si-NC group (P<0.05), the protein expression levels of Cyclin D1, p21, E-cadherin and MMP-2 were 0.25±0.02, 0.65±0.06, 0.68±0.07 and 0.27±0.03, respectively, statistically different from 0.88±0.08, 0.17±0.02, 0.14±0.01 and 0.89±0.09 of si-NC group (P<0.05), the proportions of S phase and G(2) phase in the si-TPT1-AS1 group were (17.82±1.03)% and (34.15±2.29)%, respectively, significantly different from (35.14±2.61)% and (16.84±1.21)% in the si-NC group (P<0.05). The luciferase activity of cells in the WT-TPT1-AS1+ miR-30c-5p group was 0.26±0.02, lower than 0.92±0.09 in the WT-TPT1-AS1+ miR-NC group (P<0.05). The cell survival scores in the si-TPT1-AS1+ anti-miR-30c-5p group were 0.450±0.081, 0.200+ 0.045, 0.070±0.010, 0.026±0.004 after treatment with 2, 4, 6, 8 Gy irradiation, higher than 0.285±0.043, 0.075±0.014, 0.028±0.004, 0.006±0.001 of si-TPT1-AS1+ anti-miR-NC group (P<0.05).

Abstract
Objective: To explore the experience of intimate partner-related violence (IPV) and its correlation with high-risk sexual behaviors among MSM. Methods: MSM were recruited in Ji'nan, Qingdao, and Jining of Shandong province from April to July 2019. Information on socio-demographic characteristics, AIDS prevention and control knowledge, IPV experience in the last year and high-risk sexual behaviors in the previous six months was collected by face-to-face questionnaire. EpiData 3.1 and SPSS 24.0 software were used for data cleansing and statistical analysis. Results: The average age of the 1 122 MSM was (29.80±8.78) years, with 68.1% (764/1 122) unmarried. 9.8% (110/1 122) had IPV experiences in the past year. MSM who came from Jining and Qingdao, living in the local area for more than two years, met their sexual partners in bar/bathroom/park, having no basic knowledge about AIDS, being drug users, and diagnosed with STD in the previous year, had a higher proportion of IPV experiences in the last year (P<0.05). 49.0% (550/1 122) and 20.9% (234/1 122) had unprotected anal intercourse and group sex behavior during the past six months, respectively. The results of multivariate logistic regression showed that MSM who experienced IPV were likely to have unprotected anal intercourse and group sex behavior during the past six months (aOR = 1.82, 95%CI: 1.14-2.91;aOR = 3.30, 95%CI: 2.10-5.20) than those did not experience IPV. Conclusions: IPV exists in the MSM population, and the IPV experience is positively associated with high-risk sexual behaviors. Targeted intervention to reduce the risk of high-risk sexual behaviors should be taken among MSM who experienced IPV.

Abstract
Tall fescue (Festuca arundinacea) is an important grass species worldwide, but temperature stress severely affects its distribution and yield. Transcription factors (TFs), as the master switches in sophisticated regulatory networks, play essential roles in plant growth development and abiotic stress responses. In this study, the comparative transcriptome analysis was performed to explore the commonalities and differences in the response of TFs to the heat (40 °C), cold (10 °C) and control (22 °C) conditions. A total of 877 TF genes belonging to 35 families were identified. Most of them (784) were differentially expressed genes (DEG), indicating TF genes actively responded to temperature stress. The expression of bZIP and GTF family members was up-regulated when exposed to both heat and cold, but conversely, the expression of the most WRKY and NAC families members decreased. The HSF and GTE families and DREB2B were up-regulated upon heat, while bHLH, MYB, HD-ZIP and ERF families were elevated under cold stress. The TFs involved in 'Plant hormone signal transduction', 'Plant-pathogen interaction', 'Circadian rhythm' play major roles in responding to temperature stresses. The results showed the temperature threats up-regulated the expression of stress tolerance-related genes, and down-regulated those genes associated with growth and disease resistance, indicating TFs exert crucial roles in plant adaptation to an adverse environment. This study profiled the responsive pattern of TFs to temperature stresses, partially explained the mechanism of adaptations of cold-season forage crops and screened many candidate stress-tolerant TF genes.

Abstract
Objective: To examine clinical efficacy and prognostic factors of hepatocellular carcinoma(HCC) patients with different China Liver Cancer Staging (CNLC) after hepatectomy. Methods: From January 2010 to December,2019,549 patients underwent surgical resection and pathologically proven HCC were retrospectively reviewed in the First Affiliated Hospital of Nanjing Medical University. There were 462 males(84.2%) and 87 females(15.8%);the median age was 57 years (range: 21-84 years). Preoperative parameters,intraoperative and postoperative conditions,and postoperative pathological examination were observed.Survival analysis was performed by Kaplan-Meier method and the Log-rank test. Factors associated with disease-free survival(DFS) and overall survival(OS) of HCC patients were identified using univariate and multivariate Cox proportional hazards regression models. Results: Among the 549 patients underedwent liver resection,200 patients(36.4%) belonged to CNLC Ⅰa,whiles 148 patients(27.0%) belonged to CNLC Ⅰb. Furthermore,there were 49 patients(8.9%) with CNLC Ⅱa,32 patients(5.8%) with CNLC Ⅱb, 101 patients(18.4%) with CNLC Ⅲa and 19 patients(3.5%) with CNLC Ⅲb.The 1-,3-,5-,10-year OS for the entire cohort was 83.8%,69.0%,54.2%,37.7%,respectively,while 1-,3-, 5-year DFS was 61.0%,44.2%,36.0%, respectively. The 1-,3-, 5-year OS and DFS for CNLC Ⅰa were 97.3%,90.6%,80.5% and 83.9%,65.0%,54.0%,respectively;The 1-, 3-, 5-years OS and DFS for CNLC Ⅰb were 87.9%,71.0%,47.7%,and 58.4%,42.3%,33.4%,respectively.The 5-year OS for CNLC Ⅱa (37.2%) and Ⅱb(44.3%) were similar to CNLC Ⅰb. The 1-, 3-, 5-year OS and DFS for CNLC Ⅲb were 35.3%,13.2%,0 and 23.5%,0 and 0,respectively. Univariate analysis showed that preoperative symptoms,AFP level,total protein level,AST level,total bilirubin level,intraoperative blood loss,intraoperative or postoperative blood transfusion,postoperative complications,tumor number and size,microvascular invasion,macrovascular invasion and tumor differentiation were prognostic factors for long-term survival(≥5 years)(all P<0.05). The multivariate analysis suggested that AST level,intraoperative blood loss,tumor number and size,macrovascular invasion and tumor differentiation were the independent prognostic factors of long-term OS (all P<0.05). Conclusions: HCC patients with different stages of CNLC have different recurrence patterns and prognosis.After strict preoperative evaluation,patients with CNLC Ⅱa-Ⅲb can also benefit from radical resection. AST level,intraoperative blood loss,tumor number,tumor size,macrovascular invasion and tumor differentiation were independent factors that affect long-term survival. This will provide an important basis for the choice of treatment and the evaluation of surgical prognosis for patients with HCC.

Abstract
In the present study, we analyzed the effects of Glycyrrhiza polysaccharide (GCP) on growth performance, serum antioxidant capacity, and biochemistry of broilers. A total of 600, one-day-old AA broilers randomly divided into 5 treatment groups with 6 replicate pens of 20 birds per cage received dietary supplementation with GCP (0, 200, 500, 1,000, and 1,500 mg/kg) for 42 d. The supplementation of GCP linearly decreased (P < 0.05) feed conversion rate on day 22 to 42. Dietary supplementation with GCP reduced (P < 0.05) serum total cholesterol on day 21 and 42 and linearly improved (P < 0.05) albumin and high-density lipoprotein cholesterol. Dietary supplementation with 1,000 or 1,500 mg/kg GCP significantly increased (P < 0.05) serum total superoxide dismutase (T-SOD) activity on day 21 and 42 and reduced (P < 0.05) serum malondialdehyde content on 21 d. Dietary supplementation with 1,000 or 1,500 mg/kg GCP significantly improved (P < 0.05) interleukin-1β (IL-1β) and interferon-γ (IFN-γ) expressions in liver on day 21 and 42. At the end of the experiment, we randomly selected 20 broilers from 3 treatment groups (0, 1,000, and 1,500 mg/kg), respectively, to perform an lipopolysaccharide (LPS)-induced acute stress experiment. The 60 broilers were divided into 6 treatment groups with 10 birds per cage. The experiment was designed as a 3 × 2 factorial arrangement with GCP (0, 1,000, or 1,500 mg/kg) and LPS (injection of saline or 1 mg/kg body weight) levels as treatments. When the grouping was finished, the broilers were immediately intraperitoneally injected with LPS or normal saline. Six hours after challenged, serum antioxidant and liver immunity were analyzed. The results showed that dietary GCP prevented LPS-induced reductions in T-SOD activity and increases in malonaldehyde content (P < 0.05). Also, dietary GCP supplementation mitigated the LPS-induced increase in IL-1β and IFN-γ in the liver. Supplementation with 1,500 mg/kg GCP showed the most optimal effect in broilers. GCP has the potential to be used as feed additive in broilers.

Abstract
Objective: To investigate the effect of down-regulating long non-coding RNA (lncRNA) and HOX transcript antisense RNA (HOTAIR) targeting miR-761 on the radiosensitivity of HCCLM3. Methods: The expression of HOTAIR in liver cancer cells HuH-7, SNU-449, HCCLM3 and normal liver cells L-02 were measured by real-time quantitative PCR. HCCLM3 cells were divided into control, Sh-NC (transfected shRNA negative control), Sh-HOTAIR (transfected HOTAIR shRNA), RAD+Sh-NC (transfected shRNA negative control and irradiated with 8Gy dose), and RAD+Sh-HOTAIR (HOTAIR shRNA was transfected and irradiated with 8Gy dose) group. Apoptosis was detected by flow cytometry, Bcl-2 Associated X Protein (Bx-2), cleaved cysteine-containing Cleaved cysteinyl aspartate specific proteinase 3 (C-Caspase-3) protein expression. Sh-NC, Sh-HOTAIR cells were irradiated with 0, 2, 4, 6, 8 Gy, and plate-clone experiments were used to determine radiosensitivity. Bioinformatics software predicted that miR-761 might be a target gene of HOTAIR, and the luciferase reporter system identified the targeting relationship. The miR-761 inhibitor, HOTAIR shRNA and inhibitor negative control, and HOTAIR shRNA were co-transfected into HCCLM3 cells, respectively. Cell apoptosis and Bax and C-cysteine-containing aspartate proteins were also measured using the above method, as well as the hydrolase-3 protein expression and cell survival fraction. Results: The expression levels of HOTAIR in liver cancer cells HuH-7, SNU-449, and HCCLM3 were higher than those in normal liver cells L-02 (1.85±0.12, 2.27±0.23, 2.68±0.15 vs 1.00±0.09, P<0.05). Compared with Sh-NC, the apoptosis rate of Sh-HOTAIR, RAD+Sh-NC cells and Bax, C-Caspase-3 protein levels are higher [Apoptotic rate: (13.47±1.32)%, (12.84±1.19)% vs (2.98±0.27)%; Bax protein: 0.74±0.08, 0.72±0.06 vs 0.42±0.06; C-Caspase-3 protein: 0.56±0.06, 0.54±0.08 vs 0.25±0.04, all P<0.05]. Compared with Sh-HOTAIR and RAD+Sh-NC, RAD+Sh-HOTAIR cell apoptosis rate and Bax, C-Caspase-3 protein levels are higher [apoptosis rate:(22.57±2.36)% vs (13.47±1.32)%, (12.84±1.19)%, Bax protein: 0.99±0.11 vs 0.74±0.08, 0.72±0.06, C-Caspase-3 protein: 1.03±0.12 vs 0.56±0.06, 0.54±0.08,all P<0.05]. Compared with Sh-NC, Sh-HOTAIR cells had lower survival scores and higher radiosensitivity (P<0.05). HOTAIR targets negative regulation of miR-761 expression. Compared with cells co-transfected with inhibitor negative control and HOTAIR shRNA, cells co-transfected with miR-761 inhibitor and HOTAIR shRNA had lower apoptosis rate after radiation treatment [(10.24±1.32)% vs (21.84±2.01))%], Bax (0.50±0.06 vs 1.01±0.10) and C-Caspase-3 protein (0.56±0.07 vs 1.05±0.14) had lower expression and higher cell survival scores (all P<0.05). Conclusion: Down-regulating lncRNA HOTAIR targets miR-761 to increase the radiosensitivity of HCCLM3.

Abstract
Objective: To investigate the safety, efficacy and prognosis of antegrade dissection re-entry (ADR) with the assistance of BridgePoint devices in opening coronary chronic total occlusion (CTO). Methods: A total of 87 consecutive patients, who underwent percutaneous coronary intervention using BridgePoint devices from April 2016 to December 2018 in Xijing Hospital, were included in this study. General information of the selected patients, features of CTO lesions and intraoperative parameters were recorded. Short-term outcomes including technical success rate (defined as achieving TIMI 3 blood flow with residual stenosis<30%), surgical success rate (defined as no major adverse cardiovascular events (MACE) occured while hospitalized), complications, and MACE during hospitalization were observed. MACE included death, recurrent myocardial infarction, target vascular reconstruction (TVR) and cardiac tamponade. Patients were followed up by outpatient or telephone visits at 30 days and 6, 12, 24 and 36 months after discharge. Results: Eighty-seven patients, aged (61±10) years with J-CTO scores (2.49±0.52) were included, and 75(86%) were male. Six patients underwent direct ADR with BridgePoint system, and all were successful. Eighty-one patients underwent rescue ADR using BridgePoint devices, and 62 of them were successful. The success rate of ADR with BridgePoint devices was 78.2% (68/87). Nine out of the 19 failed cases succeeded after the application of rescue antegrade/retrograde technique. The technical success rate was 88.5% (77/87). Coronary perforation occurred in 2 cases (2.3%), one case was treated with covered stent and the other case with tamponade was treated with pericardiocentesis. One patient developed periprocedural myocardial infarction, and one patient suffered from sudden death, and one patient had cardiac tamponade. In-hospital MACE occurred in 3 (3.4%) patients. The surgical success rate was 85.1% (74/87).The procedure time was (175±72)minutes and the amount of contrast used was (449±155)ml. During a follow-up of 17(11, 26) months, the incidence of MACE within 30 days was 4.7% (4/86), while 10.5% (9/86) within 6 months, 17.4% (15/86) within 17 months. Conclusion: Opening CTO with the assistance of BridgePoint devices is feasible and safe, with high success rate and satisfactory outcome.

Abstract
Objective: To investigate the value of sedation in colonoscopy. Methods: A retrospective cohort study of colonoscopy procedures was performed in our institution. Inclusion criteria: (1) colonoscopy procedures were performed by well-trained gastrointestinal surgeons our institution; (2) medical records were complete and colonoscopy was documented properly by notes, videos, photographs, and traceable pathological reports. Those with incomplete records or performed in other institution were excluded. According to above criteria, clinical data of 49 057 cases of clinic and hospitalization receiving diagnostic or therapeutic colonoscopyat Department of Gastric and Colorectal Surgery, Daping Hospital from July 2007 to February 2017 were collected. Among them, there were 24 638 (50.2%) males and 24 419 females, with mean age of (50.6±14.1) (4 to 98) years. Based on the application of sedation during colonoscopy, patients were divided into the sedation group (39 412 cases, 80.3%) and the non-sedation group (9 645 cases, 19.7%). Clinical characteristics of two groups were compared. Results: The sedation rate increased from 45.6% (369/810) to 94.8% (917/967) from 2007 to 2017. As compared to non-sedation group, a higher proportion of females [51.0% (20 095/39 412) vs. 44.8% (4 324/9 645), χ(2)=117.422, P<0.001] and younger median age (50.0 years vs. 51.0 years, Z=-4.774, P<0.001) were found in the sedation group, whose differences were statistically significant. In all the 9645 cases in the non-sedation group, about 5.5% (534) of them terminated the examination because of unbearable discomfort, including 244 (4.6%) males and 290 (6.7%) females (χ(2)=20.522, P<0.001). Among all the screening population who were ≥50 years old, there was no significant difference in the polyp detection rate (PDR) between the sedation group and the non-sedation group [26.7% (4 737/17 753) vs. 27.4% (1 093/3 984), χ(2)=0.937, P=0.330]. The cecal intubation rate (CIR) in the sedation group was significantly higher than that in the non-sedation group [(85.2% (14 422/16 933) vs. 76.1% (2 803/3 682), χ(2)=180.032, P<0.001]. Five cases in the sedation group developed iatrogenic colonic perforation (ICP), with none in the non-sedation group. Conclusions: The application of sedation in colonoscopy is increasingly popular. Sedation can significantly improve CIR in colonoscopy, while it has no positive influence on PDR. Meanwhile, sedation increases the medical expense and may result in higher ICP rate.

Abstract
Abstract Objective To predict the pigmentation phenotypes of Chinese populations from different language families, analyze the differences and provide reference data for forensic anthropology and genetics. Methods The HIrisPlex-S multiplex amplification system with 41 loci related to pigmentation phenotypes was constructed in the laboratory, and 2 666 DNA samples of adult males of 17 populations from six language families, including Indo-European, Sino-Tibetan, Altaic, Hmong-Mien, Tai-Kadai and Austro-Asiatic language families distributed in different regions of China were genotyped. The pigmentation phenotype category of each individual was predicted using the online prediction system (https://HIrisPlex.erasmusmc.nl/), and then the output data were statistically analyzed. Results About 1.92% of the individuals of Asian-European admixed populations from Indo-European and Altaic language families had blue eyes and 34.29% had brown or gold hair. The phenotypes of the color of eyes and hair of other populations had no significant difference, all individuals had brown eyes and black hair. There were differences in skin color of populations of different language families and geographical areas. The Indo-European language family had the lightest skin color, and the Austro-Asiatic language family had the darkest skin color; the southwestern minority populations had a darker skin color than populations in the plain areas. Conclusion The prediction results of pigmentation phenotype of Chinese populations are consistent with the perception of the appearance of each population, proving the reliability of the system. The color of eyes and hair are mainly related to ancestral components, while the skin color shows the differences between language families, and is closely related to geographical distribution of populations.

Abstract
Abstract With the development of new technologies, such as whole genome sequencing and big data, many countries have constructed large cohorts as strategic resources for precision medicine study. Related studies have significantly promoted research progress in many fields, such as medicine and biology, creating the genetic testing industry. In the forensic field, characterization technologies for features, such as biogeographic ancestry, genetic genealogy and physical appearance have emerged and developed rapidly. Compared with traditional forensic DNA technology, the new technology can search for characteristics and provide clues, quickly becoming an important means to solve difficult cases such as cold cases and accumulated cases. This paper briefly reviews the current status of the construction of large cohorts at home and abroad, and the research progress of forensic molecular phenotyping in the context of precision medicine in the context of precision medicine.

Abstract
Objective: To investigate the effect of HLA-DP gene expression on the susceptibility and disease status of neuromyelitis optica spectrum disorders (NMOSD). Methods: A total of 86 NMOSD patients (52 in acute phase and 34 in remission phase), 52 multiple sclerosis (MS) patients (20 in acute phase and 32 in remission phase) diagnosed in Department of Neurology, the Third Affiliated Hospital of Sun Yat-sen University and 29 healthy controls were enrolled prospectively. Genotyping of HLA-DP was performed. The expression levels of HLA-DP molecules in peripheral blood B cells and monocytes were measured by flow cytometry. The transcription levels of HLA-DPB1 mRNA in peripheral blood mononuclear cells (PBMC) were measured by real time-PCR. The results were compared among different groups Results: There was no statistically significant difference of the distributions of HLA-DPB1*0501/HLA-DPB1*0501, HLA-DPB1*0501/X and X/X genotypes and the frequencies of allele of HLA-DPB1*0501 among NMOSD, MS patients and healthy controls (P=0.96 and 0.71, respectively). The expression levels of HLA-DP on the surface of B cells in NMOSD patients, especially in remission phase patients, were significantly higher than those in healthy controls(212±328 and 374±394 vs 55±57, P=0.049 and 0.002, respectively). The expression levels of HLA-DP on the surface of monocytes in NMOSD patients in acute phase were significantly higher than those in healthy controls(158±175 vs 65±90, P=0.025). The transcription levels of PMBC HLA-DPB1 mRNA in acute phase and remission phase of NMOSD patients were significantly higher than those in healthy controls (3.0±1.4 and 2.9±1.3 vs 1.5±1.4, P=0.000 and 0.003, respectively). The expression levels of HLA-DP molecules on the surface of peripheral blood B cells and monocytes and the transcription levels of PMBC HLA-DPB1 mRNA in MS patients at the acute and remission stages were not significantly different from those in healthy controls. The expression levels of HLA-DP molecules on the surface of B cells in patients with HLA-DPB1*0501/HLA-DPB1*0501, HLA-DPB1*0501/X and X/X genotypes were statistically different (P=0.017). Conclusion: HLA-DP gene transcription and molecular expression levels in antigen presenting cells may affect the susceptibility and disease status of NMOSD patients, while HLA-DPB1*0501 allele may affect the transcription and molecular expression levels of HLA-DP gene in antigen presenting cells.

Abstract
BACKGROUND The immune reconstitution after initiation of highly active antiretroviral therapy (HAART) among HIV-infected individuals substantially affects patients' prognosis. However, the dynamic characteristics and predictors of reconstitution outcome remain unclear. METHODS In this study, the HIV/AIDS patients with sustained virological suppression (viral load < 50 copies/ml) after HAART were enrolled. The patients were subgrouped into immunological non-responders (INRs) (< 200 cells/μl), immunological inadequate responders (IIRs) (200 ~ 500 cells/μl) and immunological responders (IRs) (> 500 cells/μl) according to the CD4 cell count after two-year HAART. The immune reconstitution data based on the CD4+ and CD8+ cell counts with 8-year follow-up were collected for analysis. RESULTS The CD4+ cell counts in the immunological responders (IRs) were significantly higher than in the immunological non-responders (INRs) and immunological inadequate responders (IIRs) (P < 0.001). The overall CD4+ cell count and CD4/CD8 ratio in the IRs increased faster than the IIRs and INRs. The CD4+ cell count growth at 0.5 year and 1 year after HAART in the IRs was significantly higher than the IIRs and INRs. The ROC curve demonstrated that 1 year CD4+ cell count had the highest predictive value, with the best cut-off value of 188 cells/μl, the predictive sensitivity was 81.0%, the predictive specificity was 85.2%, false positive rate was 14.8%, false negative rate was 19.0%, positive predictive value (IR) was 63.0%, negative predictive value (INR) was 93.5%. CONCLUSIONS Taken together, our findings suggest that early initiation of HAART can reduce the immune reconstitution failure. The combination of baseline CD4+ cell count and baseline CD4/CD8 ratio may serve as a valid predictor of immune reconstitution prognosis after HAART.

Abstract
Abstract Objective To explore the distribution of genetic structure of Y-SNP and Y-STR genetic markers in different ethnic groups and its application in forensic science. Methods SNaPshot minisequencing was used to detect the polymorphisms of 12 Y-SNP loci in 439 males from 6 ethnic groups, including Guangxi Han, Guangxi Jing, Guangxi Miao, Guangxi Yao, Guangxi Zhuang and Guangxi Dong. DNATyperTM Y26 kit was used to multiplex-amplify 26 Y-STR loci. The PCR products were analyzed by 3130xl genetic analyzer. The network analysis of Y-STR haplotype under the same Y-SNP haplogroup was analyzed by Network 5.0 software. Results Six haplogroups defined by 12 Y-SNP loci were detected in 6 ethnic groups, and 362 haplotypes were detected in 26 Y-STR loci. The haplotype diversity was 0.996 6. In the C haplogroup, the samples from Guangxi Yao, Guangxi Zhuang and Guangxi Dong were clustered on different branches; in the O1 haplogroup, those from Guangxi Zhuang, Guangxi Miao and Guangxi Jing were relatively independent and clustered separately; in the O2 haplogroup, some samples from Guangxi Miao and Guangxi Yao were gathered in a cluster. Conclusion Based on the Y-STR network analysis of samples with identical haplogroup of Y-SNP, some ethnic groups can be preliminarily distinguished, which could be used to infer male suspects' ethnic group through detecting their genetic markers left in the crime scene.

Abstract
Objective To summarize the general characteristics and identification considerations of appraisal of post-traumatic epilepsy (PTE) in forensic clinical expertise. Methods Descriptive statistics were made on the general situations (age and sex), injury sites, PTE grading, clinical manifestations and blood drug concentrations of 30 cases of PTE. Chi-square test was performed on the differences of sex composition, age group incidences, injury sites, clinical manifestations and PTE grading. Fisher's exact probability method was used to test the differences in clinical manifestations and PTE grading of each site and the differences in PTE grading of different clinical manifestations. Results PTE occurred more frequently among 21 to 40 year olds, more in males than in females, and more frequently in the temporal lobe and frontal lobe. The clinical manifestations were mostly partial seizures and the PTE grading was mostly mild PTE. There were no statistical significance in the differences in distribution of clinical manifestations and PTE grading of injury sites (P>0.05). The difference in the PTE grading of different clinical manifestations had no statistical significance (P>0.05). The blood drug concentration of the three identified people did not reach the effective concentration, which affected the final identification opinion. Conclusion In the identification of PTE, in addition to strictly grasping the necessary factors of identification, such as the history of craniocerebral trauma, and epileptic seizures, it is also suggested that attention should be paid to the detection of blood drug concentration. Overall analysis and comprehensive evaluation should be made.

Abstract
In this work, the conversion of Ag films to silver oxide nanorod arrays with hierarchical porosity which was realized in an oxidation environment by reactive sputtering deposition of metal oxides was reported. The mechanisms from the oxidation of Ag films to the formation of hierarchical porosity were investigated by varying the deposition parameters with the determination of phase structure, hierarchical porosity, diffusion coefficient, and chemical states of elements as well as by a comparison with the oxidation of Ag films by direct exposure to plasma. The oxidation of Ag films can be ascribed to the atomic oxygen in the environment. The formation of silver oxide nanorods and the creation of hierarchical porosity were substantiated to be due to the Kirkendall effect occurring between the oxidized Ag films and the deposited metal oxides with the assistance of the shading effect in deposition. In addition, the sample temperature and the attributes of metal oxides were found to have significant effects on the formation of hierarchically structured porous silver oxide films. The principle revealed in this work is of significance for the synthesis of porous materials with hierarchical porosity, especially for fabrication of hierarchically porous silver oxide films with improved properties, which are needed in the research fields of solid-state thin film batteries, photocatalysts, bactericides, gas sensors, etc.

Abstract
Melanoma is a malignant tumor. The acquisition of stemness of melanoma cells aggravates the malignant transformation, which can be regulated by microRNAs (miRNAs, miR). MiR-363-3p is a key tumor-related miRNA, but its role in stemness and melanoma cells is still unknown. Presently, miR-363-3p, induced by hypoxia inducible factor (HIF)-2α, played a positive role in the stemness of melanoma cells. The levels of miR-363-3p and HIF-2α were upregulated in melanoma cell lines. Overexpression of HIF-2α significantly increased the levels of miR-363-3p. However, both HIF-2α knockdown and miR-363-3p inhibition inhibited the levels of the stemness markers (CD133, CD271, Jarid1B, and Nanog). Furthermore, the levels of miR-363-3p and HIF-2α were upregulated in fluorescence activated cell sorting (FACS)-sorted CD271high/+ cells. Whereas miR-363-3p depletion reduced the proportion and the spheroidization of the CD271high/+ cells, decreased the levels of CD133, CD271, Jarid1B and Nanog with restrained proliferative activity of CD271high/+ cells. Additionally, miR-363-3p was confirmed a key downstream of HIF-2α. Intriguingly, cyclin-dependent kinase inhibitor 1A [CDKN1A, p21(Cip1/Waf1)], a key inhibitor of S-phase DNA synthesis and cell cycle progression, was confirmed a target gene of miR-363-3p by luciferase reporter gene assay. The protein levels of CD133, CD271, Jarid1B and Nanog were upregulated with enhanced proliferative activity of CD271high/+ cells by inhibition of p21 in melanoma cells. In conclusion, miR-363-3p is induced by HIF-2α to promote the stemness of melanoma cells via inhibiting p21. The present study provides novel insights that HIF-2α/miR-363-3p/p21 signaling may be a potential target of research and therapy of melanoma.

Abstract
OBJECTIVES To screen the DNA methylation loci associated with the age of Han males in northern China and to construct an age estimation model. METHODS Twenty-one candidate methylation loci were screened. The DNA methylation levels of 476 blood samples from Chinese Han males were detected for 21 amplicons using EpiTYPER technology platform, and data on 153 DNA methylation loci were obtained. RESULTS After correlation analysis, 8 age-related DNA methylation loci were finally screened. CpG1, CpG2, CpG4, CpG7, CpG8 were located on TRIM59, RASSF5, Clorf132, CSNK1D, ELOVL2,CpG5, CpG6 on PDE4C, and CpG3 on chr17:21452808. Based on the 8 loci, 352 samples were used for model construction. A multivariate linear regression age estimation model was constructed (R2=0.93), with mean absolute deviation (MAD) of 2.69 years old. When 109 samples were used for model validation, the MAD was 3.80 years old. The test was repeated 3 times in 15 new samples, with MADs of 4.08, 4.68 and 3.93 years old, respectively. CONCLUSIONS The age estimation model on Han males in northern China constructed in this study can be used to estimate the age of victims and suspects and to narrow the scope of investigation, and therefore has practical application value.

Abstract
Objective: To investigate the long term efficacy of COPADM regimen in the treatment of Burkitt lymphoma (BL). Methods: The clinical data of 39 patients with BL from April 2006 to June 2017 were retrospectively analyzed. According to different chemotherapy regimens, the patients were divided into COPADM group and control group. Results: ①Of 39 BL patients, 26 were male and 13 female. The median age was 30 (11-63) years old, including 25 younger than 40 and 14 older than 40. Among them, 33 patients were in stage Ⅲ-Ⅳ, 13 patients had B symptoms and 25 patients were IPI score≥3. ② Twenty patients treated with COPADM regimen (COPADM group), the 3 year overall survival (OS) and progression-free survival (PFS) were (83.5±2.6)% and (73.2±3.1)%, respectively. Nineteen patients in the control group had a 3-year OS and EFS of (47.4±2.4) % and (42.1±2.4) %, respectively. There were significant differences in OS and EFS between the two groups (all P<0.001). ③Of the 20 patients in COPADM group, 12 were younger patients (age≤40 years), their 3-year OS and EFS were (93.7±3.9)% and (83.3±5.4)%, respectively. The other 8 patients were older than 40 years old, and their 3-year OS and EFS were (48.3±8.5) %, (37.6±6.0) %, respectively. Both OS and EFS in younger patients was significantly better than older patients (P=0.004, P=0.045). ④ There were 24 patients treated with combination of Rituximab, their 3-year OS and EFS were (73.9±9.2)% and (69.9±9.6)%, respectively. The other 15 patients were treated without Rituximab, and their 3-year OS and EFS were (51.3±13.3) % and (38.1±12.9) %, respectively. There were significant differences in OS and EFS between the two groups (P=0.042, P=0.008). Conclusion: COPADM regimen may improve the efficacy of BL. COPADM combined with Rituximab enables BL patients with greater benefit. The prognosis is significantly worse in patients older than 40 years old than in those less than 40 years old.

Abstract
In this study, we investigated the spatial distribution of Culex tritaeniorhynchus Giles, 1901 (Diptera: Culicidae) (the vector of Japanese B Encephalitis) and geo-environmental features (rice fields, forests, watercourses, and highways) correlated with their abundance in pigsties of Dao County, Hunan Province, China. First, light trapping in pigsties was carried out to determine vector density. Second, based on Advanced Land Observing Satellite remote-sensing datasets, spatial datasets of mosquito density and various geo-environmental features were constructed using Geography Information System. Finally, spatial statistical analysis and general linear regression were used to analyze the spatial distribution of vectors in relation to the geo-environmental features correlating with the abundance of mosquitoes in pigsties. As the results show, the distribution of mosquitoes in pigsties was not spatially autocorrelated, and several geo-environmental features that were either positively or negatively correlated with mosquito abundance in pigsties were identified. The application of these results to improve the control of vectors of Japanese B Encephalitis is also discussed.

Abstract
Objective: To estimate the prevalence of HIV/HCV co-infection and explore the influence factors and their interaction on HIV/HCV co-infection of patient's access to methadone maintenance treatment (MMT). Methods: A face to face interviews were conducted among 750 patients at two MMT clinics in Guangxi Zhuang Autonomous Region. The questionnaires information included demographic characteristics, HIV and HCV infection status, history of drug abuse, urine test for morphine, high risk sex behaviors, needle sharing, dropped out etc. Methods of χ(2) test one-way, multivariate logistic regression and interactions were used to analyze the related factors of HIV/HCV co-infection. Results: The study subjects included 750 participants, 18.31% (127/691) of patients were co-infected with HIV and HCV. The HIV/HCV co-infection rate in patients who shared needles with others or dropped out of treatment was 35.84% (81/226) and 19.88% (64/322) respectively, which were higher than those who have never shared needles or dropped out (9.89%, 46/465 and 17.07%, 63/369). Logistic regression analysis results showed that after adjusted for confounding factors, patients who shared needles (OR=4.50, 95%CI: 2.72-7.43) and dropped out of treatment (OR=1.71, 95%CI: 1.04-2.80) were more likely to be infected with HIV/HCV. Interaction analysis showed that sharing needles and dropping out of treatment exist additive effect on co-infection of HIV and HCV (RERI=4.21, AP=0.44, SI=1.95). Conclusions: Needle sharing and dropping out of treatment are associated with HIV/HCV co-infection. Health education, psychological counseling and other measures should be taken to reduce needle sharing and dropping out of MMT.

A 9-year-old girl developed a recurrent headaches and had a runny nose with occasional nosebleed for three years. She was diagnosed as sinusitis and the infection of upper respiratory tract, and given the corresponding treatment in local hospital several times before admitted by our hospital. In our department, a suspected metal body was found by nasal endoscopy and confirmed by CT scan. She was extracted foreign body under local anesthesia. The symptoms were relieved a week after the operation.

Abstract
Objective:To evaluate the diagnostic value of ultrasound patterns of 2015 American Thyroid Association (ATA) guidelines, color Doppler flow imaging (CDFI), superb microvascular imaging (SMI), and spectral Doppler in the differentiation of benign and malignant thyroid nodules.Method:The study included 254 thyroid nodules confirmed by fine needle aspiration cytology (FNAC) or histopathologic examination. All nodules were detected by ultrasonography, SMI, CDFI and spectral Doppler respectively. Blood flow detection technologies (CDFI and SMI) were used to classify flow distribution characteristics of thyroid nodules according to Kim's grading criteria. The optimal threshold drawing from ROC curve is calculated to obtain the cut-off value of spectral Doppler.Result:①For benign solid nodules with peripheral flow distribution and malignant solid nodules with central blood flow distribution, the display rates of SMI are higher than those of the CDFI, the differences were statistically significant (P< 0.05). ②There was a significance difference in detecting benign and malignant nodules using spectral Doppler (P< 0.05). ③The specificity and accuracy of combinative modality 2015 ATA+SMI was significantly higher than that of ATA, SMI, and spectral Doppler. There was no significant difference between ATA+SMI and ATA+SMI+spectral Doppler for the sensitivity, specificity, and accuracy.Conclusion:SMI had a better detection rate of blood vessels than CDFI and contribute a certain value in differential diagnosis of benign and malignant thyroid nodules. The combination of 2015 ATA and SMI can improve diagnostic value in the differentiation between benign and malignant thyroid nodules.
