Abstract
The tokamak approach, utilizing a toroidal magnetic field configuration to confine a hot plasma, is one of the most promising designs for developing reactors that can exploit nuclear fusion to generate electrical energy1,2. To reach the goal of an economical reactor, most tokamak reactor designs3-10 simultaneously require reaching a plasma line-averaged density above an empirical limit-the so-called Greenwald density11-and attaining an energy confinement quality better than the standard high-confinement mode12,13. However, such an operating regime has never been verified in experiments. In addition, a long-standing challenge in the high-confinement mode has been the compatibility between a high-performance core and avoiding large, transient edge perturbations that can cause very high heat loads on the plasma-facing-components in tokamaks. Here we report the demonstration of stable tokamak plasmas with a line-averaged density approximately 20% above the Greenwald density and an energy confinement quality of approximately 50% better than the standard high-confinement mode, which was realized by taking advantage of the enhanced suppression of turbulent transport granted by high density-gradients in the high-poloidal-beta scenario14,15. Furthermore, our experimental results show an integration of very low edge transient perturbations with the high normalized density and confinement core. The operating regime we report supports some critical requirements in many fusion reactor designs all over the world and opens a potential avenue to an operating point for producing economically attractive fusion energy.

Abstract
Objective: To investigate the clinical efficacy and safety of ferric derisomaltose injection versus iron sucrose injection in the treatment of iron deficiency anemia (IDA) . Methods: A total of 120 patients with iron deficiency anemia admitted from June 2021 to March 2023 were given intravenous iron supplementation with ferric derisomaltose to assess the efficacy and safety of hemoglobin (HGB) elevation before and after treatment. Simultaneously, the clinical effects of iron supplementation with iron sucrose were compared to those of inpatient patients during the same period. Results: Baseline values were comparable in both groups. Within 12 weeks of treatment, the elevated HGB level in the ferric derisomaltose group was higher than that of the iron sucrose group, with a statistical difference at all time points, and the proportion of HGB increased over 20 g/L in the patients treated for 4 weeks was higher (98.7%, 75.9% ). During the treatment with ferric derisomaltose and iron sucrose, the proportion of mild adverse reactions in the ferric derisomaltose group was slightly lower than that of the iron sucrose group, and neither group experienced any serious adverse reactions. The patients responded well to the infusion treatment, with no reports of pain or pigmentation at the injection site. Conclusion: The treatment of IDA patients with ferric derisomaltose has a satisfactory curative effect, with the advantages of rapidity, accuracy, and safety. Therefore, it is worthy of widespread clinical use.

Abstract
Objective: To analyze and summarize the trends and hot spots in the field of neurological damage caused by electric welding operations, and to provide ideas for new researches by searching the domestic and international literature. Methods: In December 2022, using Web of Science Citation Index (Web of Science), China Journal Full-Text Database (CNKI) and Wanfang Database as search databases, literature search was conducted on the Chinese and English search terms related to eletrical welding operations and neurological damage. The bibliometric analysis software VOSviewer 1.6.18 and CiteSpace 6.1.6 were used to visualize the publication year, publication quantity, country, research institution and key words of the literature. Results: A total of 309 articles (112 in Chinese and 197 in English) were included in this study. The first domestic and international papers were published in 1976 and 1994 respectively, and the number of papers reached the peak in 2006 and 2018, and then showed a downward trend to varying degrees. In China, Shandong First Medical University (including Shandong Institute of Occupational Health and Occupational Disease Prevention and Shandong Academy of Medical Sciences) and Wuhan University of Science and Technology had the largest number of publications. The 309 articles were from 52 Chinese journals and 86 English journals. The co-occurrence analysis of key words showed that the domestic research mainly focused on eletrical welding operation, welding workers, neurobehavioral function and manganese, and the nervous system damage caused by manganese in welding smoke was the field of international attention. Long term exposure, risk, and performance were key buzzwords in the field. Conclusion: The research focus in the field of nervous system damage caused by electric welding operation has an obvious trend of time evolution, gradually transiting from clinical manifestations to its toxic mechanism and early biomarkers.

Abstract
Objective: To investigate the expression levels of thymocyte selection related high mobility group proteins (TOX) and different inhibitory receptors in peripheral blood CD8+T cells of patients with aplastic anemia (AA), and to conduct correlation analysis. Methods: From September 2019 to November 2020, 27 AA patients in the Department of Hematology, General Hospital of Tianjin Medical University were retrospectively selected, including 21 males and 6 females, with a median age [M (Q1, Q3)] of 48 (30, 72) years. Thirty-three healthy controls, included 17 males and 16 females, with a median age of 46 (27, 69) years. The expression levels of TOX, programmed cell death receptor-1 (PD-1), T-cell immunoglobulin and mucin domain 3 (TIM-3), cytotoxic T-lymphocyte associated antigen-4 (CTLA-4), T-cell immune receptor with immunoglobulin (Ig) and immunoreceptor tyrosine-based inhibitory motif (ITIM) domain (TIGIT), perforin and granzyme B in peripheral blood CD8+T cells from AA patients and healthy controls were detected by flow cytometry. The correlation between TOX expression levels and different inhibitory receptors was analyzed using Pearson correlation analysis. Results: The expression levels of TOX, PD-1, TIM-3, CTLA-4, TIGIT, perforin, and granzyme B in peripheral blood CD8+T cells of AA patients were 47.33%(41.47%, 56.61%), (30.61±12.37)%, (39.94±10.84)%, (6.21±3.40)%, (51.45±20.21)%, (71.32±22.46)%, and (52.39±23.99)%, respectively, which were higher than those of healthy controls 27.32%(21.64%, 46.96%), (21.29±10.01)%, (21.11±3.00)%, (1.31±0.34)% (30.80±13.40)%, (46.72±22.53)%, (21.75±16.43)% (all P<0.05). The expression level of TOX in CD8+T cells was positively correlated with the expression levels of PD-1, TIM-3, CTLA-4, TIGIT, perforin, and granzyme B (r=0.49, 0.65, 0.70, 0.54, 0.58, 0.48, all P<0.05). Conclusion: The expression levels of TOX and different inhibitory receptors on peripheral blood CD8+T cells in AA patients are higher than those in the healthy control group, and the expression levels of TOX and different inhibitory receptors are positively correlated.

Abstract
Objective: This study aimed to investigate the role and clinical significance of MUC4 gene mutations in thrombotic events in patients with classic paroxysmal nocturnal hemoglobinuria (PNH) patients. Methods: A retrospective analysis was conducted on the clinical data and gene sequencing results of 45 patients with classic PNH admitted to the Department of Hematology, Tianjin Medical University General Hospital, from June 2018 to February 2022. MUC4 gene mutations in patients with classic PNH were summarized, and the risk factors for thrombotic events in these patients were analyzed. Additionally, the effects of MUC4 gene mutations on the cumulative incidence and survival of thrombotic events in patients with classic PNH were determined. Results: The detection rate of MUC4 gene mutations in patients with classic PNH who experienced thrombotic events (thrombotic group) was 68.8% (11/16), which was significantly higher than that in the non-thrombotic group [10.3% (3/29) ] (P<0.001). All mutations occurred in exon 2. MUC4 mutation (OR=20.815, P=0.010) was identified as an independent risk factor for thrombotic events in patients with classic PNH. The cumulative incidence of thrombotic events was 78.6% (11/14) in the MUC4 gene mutation group (mutation group) and 16.1% (5/31) in the non-mutation group, showing a statistically significant difference between the two groups (P<0.001). Survival analysis showed a lower overall survival (OS) rate in the thrombotic group compared with that in the non-thrombotic group [ (34.4±25.2) % vs. (62.7±19.3) % ] (P=0.045). The OS rate of patients was (41.7±29.9) % in the mutation group and (59.1±18.3) % in the non-mutation group (P=0.487) . Conclusion: MUC4 gene mutations are associated with an increased incidence of thrombotic events in classic PNH patients, highlighting their role as independent risk factors for thrombosis in this population. These mutations can be considered a novel predictive factor that aids in evaluating the risk of thrombosis in patients with classic PNH.

Abstract
Objective: To analyze the drug resistance and genomic characteristics of Salmonella enterica serovar London isolated from clinical and food sources in Hangzhou City from 2017 to 2021. Methods: A total of 91 Salmonella enterica serovar London strains isolated from Hangzhou City from 2017 to 2021 were analyzed for drug susceptibility, pulsed field gel electrophoresis (PFGE) typing and whole genome sequencing. Multilocus sequence typing (MLST), core genome multilocus sequence typing (cgMLST) and detection of drug resistance genes were performed by using the sequencing data. Phylogenetic analysis was conducted to compare the 91 genomes from Hangzhou City with 347 genomes from public databases. Results: No significant difference in the drug resistance rate was observed between clinical strains and food strains to 18 drugs in Hangzhou City(all P>0.05), and the multidrug resistance (MDR) rate was 75.8% (69/91). Most strains were resistant to 7 drug classes simultaneously. One strain was resistant to Polymyxin E as well as positive for mcr-1.1, and 50.5% (46/91) of the strains were resistant to Azithromycin and were positive for mph(A). All 91 Salmonella enterica serovar London strains were ST155, which were subdivided into 44 molecular types by PFGE and 82 types by cgMLST. Phylogenetic analysis showed that most strains from Hangzhou City (83/91) were clustered together, and a small number of human isolates from Europe, North America and pork isolates from Hubei and Shenzhen were mixed in the cluster. Other strains from Hangzhou City (8/91) were closely related to strains from Europe, America and Southeast Asia. Strains isolated from pork were the most closely related to clinical strains. Conclusion: The epidemic of Salmonella enterica serovar London in Hangzhou City is mainly caused by the spread of ST155 strains, which is mainly transmitted locally. At the same time, cross-region transmission to Europe, North America, Southeast Asia, and other provinces and cities in China may also occur. There is no significant difference in the drug resistance rate between clinical strains and food strains, and a high level of MDR is found in the strains. Clinical infection of Salmonella enterica serovar London may be closely related to pork consumption in Hangzhou City.

Abstract
Objective: To analyze the expression of C-X-C chemokine receptor 5 (CXCR5)+CD8+ T cells and plasma C-X-C motif chemokine 13 (CXCL13) in severe aplastic anemia (SAA) patients and their correlations with hematological parameters. Methods: The clinical data of 35 SAA patients in the Hematology Department of Tianjin Medical University General Hospital from January 2018 to September 2021 were retrospectively analyzed. The patients were divided into two groups according to whether they had received the medication: untreated SAA group and recovery SAA group. In untreated group, there were 18 patients who had not received any medication, with 9 males and 9 females, and aged 51 (18-76) years. In recovery SAA group, there were 17 patients who were separated from component blood transfusion after the immunosuppressive treatment with anti-thymocyte globulin (ATG) combined with cyclosporine A (CsA), with 7 males and 10 females, and aged 46 (16-70) years. Meanwhile, 20 healthy controls were also selected, including 8 males and 12 females, and aged 45(15-72) years. Peripheral blood and bone marrow samples were collected from SAA patients, while peripheral blood samples were obtained from healthy controls. Flow cytometry was used to detect the percentage of CXCR5+CD8+ T cells in peripheral blood and bone marrow samples. The concentration of plasma CXCL13 was measured by enzyme-linked immunosorbent assay (ELISA). The correlations between the percentage of CXCR5+CD8+ T cells and the concentration of CXCL13, as well as the correlations between these two parameters and the hematological parameters were analyzed by Spearman correlation analysis. Results: The proportion of CXCR5+CD8+ T cells in the bone marrow of untreated SAA group was (4.9±2.9)%, which was higher than that of recovery SAA group (2.7±1.5)%, with a statistically significant difference (t=2.34, P=0.027). The proportion of CXCR5+CD8+ T cells in peripheral blood of untreated SAA group, recovery SAA group and healthy control group was (8.4±4.2)%, (3.8±2.3)% and (2.6±2.0)% respectively. The proportion of CXCR5+CD8+ T cells in peripheral blood of untreated SAA group was higher than that of recovery SAA group and healthy control group (both P<0.05). The plasma CXCL13 concentration in untreated SAA group was (97.2±46.8) ng/L, which was significantly higher than that in recovery SAA group [(54.9±20.9) ng/L] and healthy control group [(47.6±17.3) ng/L] (both P<0.05). The proportion of CXCR5+CD8+ T cells in peripheral blood of SAA patients was positively correlated with the concentration of plasma CXCL13 (r=0.545, P<0.001). The proportion of peripheral blood CXCR5+CD8+ T cells in SAA patients was negatively correlated with white blood cell count, platelets count, percentage of neutrophils, absolute neutrophils count, percentage of reticulocytes, absolute reticulocytes count, bone marrow myeloid cells, bone marrow erythroid cells and megakaryocytes count (r=-0.556, -0.392, -0.617, -0.615, -0.395, -0.543, -0.432, -0.484 and -0.523, all P<0.05). The proportion of peripheral blood CXCR5+CD8+ T cells was positively correlated with the percentage of peripheral blood lymphocytes and bone marrow lymphoid cells (r=0.593 and 0.556, both P<0.05). Meanwhile, the concentration of plasma CXCL13 in SAA patients was negatively correlated with white blood cell count, absolute neutrophils count, percentage of reticulocytes, absolute reticulocytes count and bone marrow myeloid cells (r=-0.447, -0.446, -0.498, -0.407 and -0.456, all P<0.05), but positively correlated with bone marrow lymphoid cells (r=0.384, P<0.05). Conclusions: The proportion of CXCR5+CD8+ T cells and the concentration of plasma CXCL13 increases in SAA patients. The proportion of CXCR5+CD8+ T cells in peripheral blood is positively correlated with the concentration of CXCL13. Moreover, the proportion of CXCR5+CD8+ T cells and the concentration of CXCL13 are correlated with many hematological parameters, which may play a critical role in the immune pathogenesis of SAA.

Abstract
Objective: To describe fertility and explore factors associated with it among pre-conception couples of childbearing age. Methods: Based on the pre-conceptional offspring trajectory study of the School of Public Health of Fudan University, couples of childbearing age who participated in the pre-conception physical examination in Shanghai Jiading District from 2016 to 2021 were recruited and followed up. Couples' time to pregnancy (TTP) was analyzed and Cox proportional hazards regression model was used to explore the factors associated with TTP. Kaplan-Meier was used to calculate each menstrual cycle's cumulative pregnancy rate. Results: A total of 1 095 preconception couples were included in the analysis, the M(Q1,Q3)of TTP was 4.33 (2.41, 9.78) menstrual cycles. Age of women (FR=0.90, 95%CI: 0.85-0.95, P<0.001), women who were overweight or obese before pregnancy (FR=0.36, 95%CI: 0.24-0.55, P<0.001), women who were exposed to second-hand smoking (FR=0.63, 95%CI: 0.44-0.92, P=0.016), women whose home or office had been renovated in the past 2 years and had a particular smell (FR=0.46, 95%CI: 0.26-0.81, P=0.008) were risk factors for impaired fertility. Regular menstrual cycles (FR=1.64, 95%CI: 1.16-2.31, P=0.005), females who often drank tea/coffee (FR=1.55, 95%CI: 1.11-2.17, P=0.011) and males who took folic acid before conception (FR=2.35, 95%CI: 1.38-4.23, P=0.002) were associated with better fertility. The cumulative pregnancy rate of 3, 6, and 12 menstrual cycles was 37.6%, 64.4%, and 78.4%, respectively. Conclusion: Older couples, overweight or obesity before pregnancy, irregular menstruation, exposure to secondhand smoke and decoration pollutants in females are associated with impaired fertility. Frequent tea/coffee drinking before pregnancy in females and taking folic acid before pregnancy in males are associated with shortened conception time.

Abstract
The Surface Eroding Thermocouple (SETC) is a robust diagnostic utilized in DIII-D to provide fast, edge-localized modes (ELMs) resolved heat flux measurements, in particular in geometric regions that are too shadowed for traditional infrared thermography. In order to further investigate the power dissipation in the divertor region, a combination of flush-mounted and recessed SETCs was developed to assess the effect on surface heating from non-charged particles at the divertor target. Utilizing the Divertor Materials Evaluation System sample exposure platform, the first demonstration of the feasibility of using this new method to distinguish between the heat flux from charged particles and that from neutrals and radiative heating was achieved. This paper details the process of using the combination of flush SETCs and recessed SETCs to measure the multiple heat flux components at the divertor target and further discusses how to determine two important ratios, α (ratio of heat flux from charged particles deposit on recessed SETC to that deposit on flush SETC) and β (ratio of heat flux from non-charged particles deposit on recessed SETC to that deposit on flush SETC), in the estimation of the heat flux from non-charged particle sources. Using a time dependent ratio α, it was found that ∼50% of the total incident heat flux is attributable to the non-charged particles in the fully detached open divertor in DIII-D. Finally, the new application of similar SETC diagnostics in the Small Angle Slot divertor with a V-like configuration and partial tungsten coated surface (SAS-VW) is also introduced.

Abstract
A comprehensive review of the research of the effectiveness of influenza vaccine and 23 valent pneumococcal polysaccharide vaccine (PPV23) in patients with chronic obstructive pulmonary disease (COPD) both at home and abroad in recent years showed that influenza vaccine and PPV23 immunization can significantly reduce the risk for influenza and pneumonia in COPD patients, and reduce the acute exacerbation of disease and related hospitalization. In particular, the influenza vaccination can also reduce the risk for ischemic heart disease, acute coronary syndrome, ventricular arrhythmia, lung cancer, dementia and death in the patients, and the immunization of both vaccines has a more significant protective effect. It is recommended by authoritative guidelines both at home and abroad that COPD patients can receive influenza vaccine and PPV23. At present, the coverage of domestic influenza and pneumococcal vaccines are low, and there are less studies in the applications of both vaccines in patients with COPD. Effective measures should be taken to strengthen the health education and increase the vaccination coverage. Additionally, the clinical research of influenza vaccine and PPV23 for COPD patients, especially the analysis on clinical benefit of immunization of both vaccines, should be further strengthened to effectively improve the survival and prognosis of COPD patients.

Abstract
As an independent disease, aplastic anemia (AA) has been recognized for more than a century. When AA is diagnosed, other non-AA bone marrow failures should be excluded. It is termed as exclusive diagnosis of AA. The exclusive diagnosis of AA is helplessly based on that there is no parameter by which AA can be sensitively and specifically diagnosed now. So further searching for the meaningful diagnostic parameters of AA should be carried on to establish a direct diagnostic protocol of this disease and make it possible to differentiate it clearly from other bone marrow failure disease such as congenenital bone marrow failure, hypoplastic myelodysplastic syndromes, AA-paroxysmal nocturnal hemoglobinuria syndromes, large granules lymphocyte leukemia, clonal cytopenia of undetermined significance, immunorelated pancytopenia, acute hemopoietic arresting and idiopathic cytopenia of undetermined significance. The new markers and technologies being helpful for distinguishing AA from other bone marrow failures should be used in diagnosing AA. Correct understanding and application of exclusive diagnosis is not only related to the correctness of diagnosis and treatment of excluded diseases, but also to the quality of AA diagnosis, treatment and research.

Abstract
Objective: To examine the clinical effect of acellular bovine pericardium patch in implant based immediate breast reconstruction. Methods: The clinicopathological information of 141 breast cancer patients, who admitted to Department of Breast Reconstruction and Oncoplastic Surgery, Tianjin Medical University Cancer Hospital, underwent immediate mammoplasty with implants combined with acellular bovine pericardium patches were analyzed from June 2016 to October 2019. All patients were female, with the age of (38.8±8.5) years (range: 13 to 60 years). The body mass index was (21.9±2.5) kg/m2 (range: 16.0 to 32.3 kg/m2). There were 39 cases of duct carcinoma in situ, 46 cases of stage Ⅰ, 40 cases of stage Ⅱ and 16 cases of stage Ⅲ. All patients received nipple-areola-sparing mastectomy or skin-sparing mastectomy with sentinel lymph node biopsy or axillary lymph node dissection, and prosthesis implantation with sub-pectoralis combined with breast patch. The correlation of clinicopathological characters and complications was assessed by t test, χ2 test, Fisher's exact probability method and Logistic regression. Pre-and post-operative aesthetic, quality of life scores were recorded. Results: The operation time (M(IQR)) was 3.6(1.5) hours (range: 3.0 to 6.5 hours). The early postoperative complication rate was 22.0% (31/141), prosthesis removal was the main postoperative complication, accounting for 64.5% (20/31) of the total complications, of which 15 cases occurred in the first 30 patients. The follow-up time was 28(8) months (range: 20 to 53 months), The most frequent long-term complications were capsular contracture and implant displacement, with the incidence of 11.2% (14/125) and 10.4% (13/125), respectively. Multivariate analysis showed that prosthesis volume ≥300 ml (OR=8.173, 95%CI: 1.302 to 51.315, P=0.021) and peri-areolar incision (OR=7.809, 95%CI: 2.162 to 28.211, P<0.01) were independent relative factors for the occurrence of short-term postoperative local complications. After 2 years of operation, the score of breast appearance satisfaction was 71.7±15.5, postoperative effect satisfaction was 90.4±9.5, psychological satisfaction was 90.7±17.1, sexual satisfaction was 70.1±25.1. The immediate postoperative satisfaction rate at discharge was 95.4% (134/141), and 17.6% (22/125) of patients had the intention to received revision surgery. Conclusions: Prosthesis volume ≥300 ml and peri-areolar incision were independent realtive factors for short-term local complications after bovine pericardium patch combined with prosthesis implantation in the immediate breast reconstruction. After completing the learning curve, the postoperative complications of the procedure could be decreased.

Objective: To understand the chest CT features of aluminosis caused by alumina and to improve the understanding of the imaging findings of alumina pneumoconiosis. Methods: The chest CT findings of 17 cases of alumina-induced pneumoconiosis and 30 cases of silicosis (the control group) diagnosed in Zibo Occupational Disease Prevention Hospital from April 2015 to July 2020 were analyzed retrospectively. The characteristics of fibrosis of the two kinds of pneumoconiosis and the incidence of size, density, distribution, tractive bronchiectasis, pleural thickening and interlobular septal thickening of pneumoconiosis nodules were compared. Results: Alumina pneumoconiosis showed nodules with thickened interlobular septal of 66.67% (12/18) , honeycomb lung of 22.22% (4/18) , ground glass shadow of 61.11% (11/18) , simple nodules of 11.11% (2/18) , and no fusion mass. In the control group, the long-line fibrosis of nodules with thickened interlobular septal were 16.67% (5/30) , 6.67% (2/30) with honeycomb lung and ground glass density shadow, 23.33% (7/30) with fusion mass and 53.33% (16/30) with simple nodule. There were significant differences in CT findings of nodules with thickened interlobular septal, ground glass density shadow, fused mass and simple nodules between the two groups (P<0.05) . The interstitial beaded nodules were seen in 18 cases of alumina pneumoconiosis, 50.00% (9/18) of them were beaded nodules, 61.33% (46/75) of low density nodules and 38.89% (7/18) of central lobular nodules were seen in alumina pneumoconiosis. The average width of nodules was (1.29±0.38) mm. Central lobular nodules were seen in all 30 cases of silicosis, 10.00% (3/30) were mainly beaded nodules, low density nodules were 36.29% (90/248) , and the average width diameter of nodules was (1.85±0.58) mm. There were significant differences between the two groups (P<0.05) . Alumina pneumoconiosis was often accompanied by traction bronchiectasis, pleural thickening and interlobular septal thickening (11, 18, 17 cases, 61.11%, 100.00%, 94.44%) , compared with the control group (9, 18, 18 cases, 30.00%, 60.00%, 60.00%) . The differences were statistically significant (P<0.05) . The maximum CT value of noncalcified mediastinal lymphnodes in alumina pneumoconiosis was (103.43±26.33) HU, which was higher than that of the control group[ (75.22±16.70) HU], and the difference was statistically significant (P<0.05) . Conclusion: Alumina pneumoconiosis chest CT shows slightly low-density beaded nodules, thickened interlobular septal, and pulmonary interstitial fibrosis of ground-glass shadows, mostly combines with stretched bronchiectasis, thickened pleura, and mediastinum increased lymph node density.

Abstract
The DIII-D small angle slot (SAS) divertor is designed for divertor physics studies with enhanced neutral confinement and special target geometries in a closed divertor. The closed nature of the SAS makes optical diagnostic measurements difficult, so a specially designed, multipurpose array of Langmuir probes has been implemented to study the plasma conditions in and around the slot. The probes are spaced to provide at least 2 mm resolution (shorter than the energy decay length) of the near scrape-off layer when mapped to the outer mid-plane. Due to space limitations at the bottom of the slot, a novel spring-loaded probe and tile design was developed to clamp several short rooftop probe tips and insulators to the cooled baseplate. Initial probe measurements revealed tile to tile edge shadowing, especially where magnetic field line surface angles were less than 1°. Additionally, it was found, using three Langmuir probes (at 90°, 180°, and 270°), that the strike point variation of ±5 mm radially around the torus was not well aligned with the circular slot geometry [Watkins et al., Nucl. Mater. Energy 18, 46 (2019)]. These issues were resolved by (1) designing tiles with all probes mounted near the tile center instead of near the edges and (2) aligning these new custom tiles to the measured strike point toroidal surface with a very accurate laser scanning alignment tool. Post-alignment Langmuir probe measurements and plasma behavior demonstrated close agreement at two separate toroidal locations that were 45° apart.

Abstract
Objective: To investigate the correlation between serum ferritin (SF) level and liver damage in the acute stage of dengue fever. Methods: A retrospective study was conducted to analyze 171 cases diagnosed with dengue fever as dengue fever group and 130 healthy patients as control group in Hangzhou 3A grade hospital from July to December 2017. Clinical data, SF and liver function related indicators were collected from both groups: alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) to analyze the correlation between liver damage and SF in patients with dengue fever. Results: ALT, AST, and SF levels were significantly higher in the dengue fever group than those in the healthy control group (Z = 11.553, 15.054 and 15.163, P < 0.001). SF levels were higher in the dengue fever combined with liver damage group than those without the liver damage group (z = 6.930, P < 0.001). However, there was no statistically significant differences in age, gender, peak body temperature, and history of liver disease (P > 0.05). In addition, Spearman's correlation analysis showed that SF was positively correlated with ALT, AST, and TBIL (r = 0.464, 0.531 and 0.315, P < 0.001). Among dengue patients with different SF levels, there were significant difference in ALT, AST levels and incidence of liver damage (H = 14.240 and 17.584, χ(2) = 49.547, P < 0.001). Patients with higher SF levels had higher ALT, AST levels and incidence of liver damage. Binary logistic regression analysis showed that hyperferritinemia (SF≥500 ng/ml) was the risk factor for dengue fever combined with liver damage (OR = 8.120, P < 0.001). Furthermore, ROC curve analysis showed that the AUC for SF to judge dengue fever combined liver damage was 0.846 (95% CI: 0.785-0.908), and the sensitivity and specificity when the SF cut-off value was 1 506 ng/ml were 74.8% and 83.3%. Conclusion: There is a certain correlation between the SF level and the degree of liver damage in acute stage of dengue fever patients, and hyperferritinemia is a risk factor for dengue fever combined with liver damage.

Abstract
Divertor detachment offers a promising solution to the challenge of plasma-wall interactions for steady-state operation of fusion reactors. Here, we demonstrate the excellent compatibility of actively controlled full divertor detachment with a high-performance (βN ~ 3, H98 ~ 1.5) core plasma, using high-βp (poloidal beta, βp > 2) scenario characterized by a sustained core internal transport barrier (ITB) and a modest edge transport barrier (ETB) in DIII-D tokamak. The high-βp high-confinement scenario facilitates divertor detachment which, in turn, promotes the development of an even stronger ITB at large radius with a weaker ETB. This self-organized synergy between ITB and ETB, leads to a net gain in energy confinement, in contrast to the net confinement loss caused by divertor detachment in standard H-modes. These results show the potential of integrating excellent core plasma performance with an efficient divertor solution, an essential step towards steady-state operation of reactor-grade plasmas.

Abstract
Objective: To observe the efficacy and safety of Kangbingdu granules (KBD) in the treatment of influenza. Methods: A multicenter, randomized, double-blind, double-dummy, and positive-drug parallel control trial was conducted in 27 Grade ⅢA hospitals in China and the subjects were randomly assigned to the KBD test group or the oseltamivir phosphate capsule control group at a ratio of 1∶1. 200 subjects were planned to be enrolled in each group. The experimental group was given KBD (18g each time, 3 times a day) and oseltamivir phosphate simulator orally, while the control group was given oseltamivir phosphate capsule (75 mg each time, twice a day) and KBD simulator orally for 5 days. The primary efficacy indicators included the remission time of major clinical symptoms and the time of complete defervescence. The secondary efficacy indicators included dosage of acetaminophen, the change of traditional Chinese medicine (TCM) syndrome score and the remission time of other important clinical symptoms. The efficacy of KBD in the test group and Oseltamivir phosphate control group were compared. Adverse events or adverse reactions were observed at the same time to evaluate the safety of KBD Granules. Results: A total of 393 subjects from 27 Grade ⅢA hospitals in China were enrolled. The experimental group included 195 subjects and 191 subjects (97.95%) completed the trial, While the control group included 198 subjects and 195 subjects (98.48%) completed the trial. There was no significant difference in the shedding rate and rejection rate between the two groups (P>0.05). In the Full Analysis Set (FAS), the mean age of the experimental group was (34.9±14.4) years old, with 83 males (42.78%). The mean age of the control group was (33.3±13.5) years old, with 78 males (39.59%). There were no statistically significant differences between the two groups in demographic data, physical examination, viral pathogen detection, total score of TCM syndromes and scores of each symptom at baseline (P>0.05). In the FAS, the remission time M (Q1, Q3) of major clinical symptoms was 3.0 (3.0, 4.0) days in the experimental group and 3.0 (3.0, 4.0) days in the control group, and the difference was not statistically significant (P>0.05). The time M (Q1, Q3) of complete defervescence was 34.0 (20.3, 49.0) hours in the experimental group and 36.5 (19.6, 48.8) hours in the control group, and the difference was not statistically significant (P>0.05). KBD granules had the same effect as Oseltamivir phosphate capsule (P>0.05) in terms of acetaminophen dosage, TCM syndrome effect and disappearance rate of most important clinical symptoms. Meanwhile, the disappearance rate of dizziness and chest distress on day 3 in the KBD granules group was better than that of oseltamivir phosphate capsule (P<0.05). Conclusion: KBD granules have the same efficacy as Oseltamivir Phosphate capsule in the treatment of influenza and the drug safety is good.

Abstract
Objective: To explore the clinical phenotypic characteristics of coal worker's pneumoconiosis for guiding the individualized treatment of various types of patients with coal worker's pneumoconiosis. Methods: Collect clinical data of 121 cases of coal worker's pneumoconiosis in different stages, and select 16 clinical variables (age, smoking index, years of underground dust exposure, stages of pneumoconiosis, types of work, family history, main symptoms, secondary symptoms, CAT score, imaging manifestations, FVC%, FEV(1)/FVC, FEV(1)%, DLCO%, respiratory failure complications, pulmonary heart disease complications) . Principal Component Factor Analysis (PCA) was used to analyze 16 clinical variables of 121 patients with coal worker's pneumoconiosis. Extracted 2 principal components and 8 related variables from 16 clinical variables, then coal worker's pneumoconiosis patients were divided into three types according to CCC values. Variance analysis or χ(2) test were used to analyze the characteristics of these three types of clinical data, then summarized the clinical phenotype composition ratio and clinical data characteristics. Results: The patients with coal worker's pneumoconiosis were initially divided into three types, including 73 cases (60.3%) in type 1, 18 cases (14.9%) in type 2 and 30 cases (24.8%) in type 3. Patients in type 1 are mainly middle-aged, with little damage to lung function and mild clinical symptoms, the imaging manifestations of type 1 patients are mainly diffuse nodules, and the stages of pneumoconiosis are mostly one-stage and second-stage. Patients in type 2 are mainly in middle-aged and elderly patients.the main pulmonary impairment is diffuse function decline. The clinical symptoms are severe and the imaging manifestations are complex. The stages of pneumoconiosis are one, second and third stages. Patients in type 3 are mainly middle-aged and elderly patients, with more pulmonary function impairment (decreased ventilation and diffusion) , severe clinical symptoms, complex imaging manifestations (micro nodules, emphysema, mass shadow, fibrosis) , and those pneumoconiosis stages are mainly in the second and third stages. Conclusion: According to the clinical characteristics, the patients with coal worker's pneumoconiosis were divided into 3 types by cluster analysis method, the treatment plan has certain guiding value in clinical work according to different classifications.

Abstract
In this paper, the epidemiological and clinical characteristics of severe acute respiratory syndrome (SARS), pandemic (H1N1) 2009 and COVID-19 were compared. Compared with the other two diseases, COVID-19 is more contagious, more concealed in transmission, greater infectious intensity and more severe in clinical manifestations. If the COVID-19 epidemic was not effectively controlled, it would have a serious impact on human health and even social development. Understanding the characteristics of three diseases, especially COVID-19, and improving the awareness of the harmfulness of COVID-19 are of certain significance to the implementation of the guiding principle of "scientific prevention and treatment, precise implementation of strategies" and the prevention and control of COVID-19.

Abstract
Objective: To understand the situation supported by the National Natural Science Foundation in the field of occupational diseases (H2402) in China, so as to provide a reference basis for the application and research of scientific researchers in the field of occupational diseases in China. Methods: The information system of scientific and technological achievements was used to search the financial support of the National Natural Science Foundation of China (NSFC) in the field of occupational diseases from 2010 to 2019. Results: From 2010 to 2019, a total of 55 projects were funded under the Occupational Disease code (H2402) , with a total funding of 22.33 million yuan, of which 30 were supported by the Youth Science Foundation, 20 by the Youth Science Foundation and 5 by the Regional Science Foundation. Thirty five items of the research projects focused on pneumoconiosis and other respiratory diseases which accounted for 63.64 per cent. Forty one items of scientific research projects are supported by domestic institutions of higher learning which accounted for 74.55 per cent. Conclusion: The research support of the National Natural Science Foundation of China to the field of occupational diseases (H2402) has increased steadily, but the support of different research directions and supporting units is not balanced. It is suggested that departments concerned strengthen guidance and support for the applicants in less developed areas and weak research directions of the projects in the National Natural Science Foundation.

Abstract
The structure of the edge plasma in a magnetic confinement system has a strong impact on the overall plasma performance. We uncover for the first time a magnetic-field-direction dependent density shelf, i.e., local flattening of the density radial profile near the magnetic separatrix, in high confinement plasmas with low edge collisionality in the DIII-D tokamak. The density shelf is correlated with a doubly peaked density profile near the divertor target plate, which tends to occur for operation with the ion B×∇B drift direction away from the X-point, as currently employed for DIII-D advanced tokamak scenarios. This double-peaked divertor plasma profile is connected via the E×B drifts, arising from a strong radial electric field induced by the radial electron temperature gradient near the divertor target. The drifts lead to the reversal of the poloidal flow above the divertor target, resulting in the formation of the density shelf. The edge density shelf can be further enhanced at higher heating power, preventing large, periodic bursts of the plasma, i.e., edge-localized modes, in the edge region, consistent with ideal magnetohydrodynamics calculations.

Abstract
Objective: To understand the viral genomic characteristics of a 2019-novel coronavirus (2019-nCoV) strain in the first COVID-19 patient found in Hangzhou, China. Methods: Viral RNA was extracted in throat swab and sputum sample of the patient and was performed real-time reverse transcription PCR detection and obtained viral genome by high-throughput sequencing method. Phylogenetic analysis was conducted using 29 2019-nCoV genomes and 30 β-coronavirus genomes deposited in NCBI GenBank. Fifteen genomes from Wuhan were grouped by mutation sites and others were identified by Wuhan's or specific mutation sites. Results: A 29 833 bp length genome of the first 2019-nCoV strain in Hangzhou was obtained, covering full length of the coding regions of coronavirus. Phylogenetic analysis showed that the genome was closest to the genome of a bat SARS-like coronavirus strain RaTG13 with an identity of 96.11% (28 666/29 826). Among the genes between two genomes, E genes were highly conserved (99.56%), while S genes had lowest identity (92.87%). The genome sequence similarities among 29 strains from China (Hangzhou, Wuhan, and Shenzhen), Japan, USA, and Finland, were all more than 99.9%; however, some single nucleotide polymorphisms were identified in some strains. Conclusion: The genome of Hangzhou 2019-nCoV strain was very close to the genomes of strains from other cities in China and overseas collected at early epidemic phase. The 2019-nCoV genome sequencing method used in this paper provides an useful tool for monitoring variation of viral genes.

Abstract
Since 2010, the incidence of hand, foot, and mouth disease (HFMD) has ranked top in notifiable infectious disease in China, causing economic losses to many families and the society of China. This paper summarizes the related methods, results and problems systematically in the research of economic burden of HFMD in China to provide reference for the better estimation of the economic burden caused by HFMD. Many studies showed that HFMD, especially severe and fatal cases, had posed heavy economic burden on the society. To mitigate the burden caused by HFMD, it is necessary to decrease the risk of severe and fatal cases, as well as to reduce the incidence of mild cases.

Objective: To analyze the pulmonary function and clinical features of coal worker's pneumoconiosis complicated with chronic obstructive pulmonary disease (COPD) , coal worker's pneumoconiosis and COPD, in order to improve the diagnosis and treatment of coal worker's pneumoconiosis complicated with chronic obstructive pulmonary disease. Methods: Selected patients in respiratory department of General Hospital of Jincheng Coal Industry Group were classified as pneumoconiosis complicated with COPD group (n=52) , pneumoconiosis group (n=70) and COPD group (n=50) . Clinical data were collected and compared between three groups, including age, history of smoking, BMI, pulmonary function, CAT score and complication with Hypoxemia and respiratory faliure. Results: The mean age, smoking index and BMI of the three groups were not significantly different. The FEV1% pred, FEV(1)/FVC%, DLco-SB%, FVC% pred were significantly lower in pneumoconiosis complicated with COPD group than pneumoconiosis group (P<0.05) ; The FEV(1)% pred, DLco-SB%, FVC% pred were significantly lower in pneumoconiosis complicated with COPD group than COPD group (P<0.05) , but, the FEV(1)/FVC% was no significant different between pneumoconiosis complicated COPD group and COPD group (P>0.05) ; The CAT score for clinical symptoms of pneumoconiosis complicated with COPD group was significantly higher than that of pneumoconiosis group (P<0.05) , but there was no significant difference between pneumoconiosis complicated COPD group and COPD group (P>0.05) . The rate of hypoxemia in coal workers' pneumoconiosis combined with chronic obstructive pulmonary disease was 78.8%, which was higher than that of coal workers' pneumoconiosis group (61.4%) and chronic obstructive pulmonary disease group (72%) ; The respiratory failure rate of coal worker's pneumoconiosis combined with chronic obstructive pulmonary disease group was 44.2%, which was higher than that of coal worker's pneumoconiosis group (4.3%) and chronic obstructive pulmonary disease group (16%) . Conclusion: In pneumoconiosis patients, once complicate with COPD, the pulmonary function indexes are worse, the clinical symptoms are heavier, and the probability of hypoxemia and respiratory failure are higher. Compared with the COPD group, the patients with pneumoconiosis complicated with COPD have more restrictive ventilation dysfunction and diffuse dysfunction, and the clinical symptoms are heavier, and the probability of combined respiratory failure is higher.

Abstract
Objective: To understand the situation and characteristics of out-patient utilization of urban and rural pneumoconiosis patients in Jiangsu province, and to provide a reference for the formulation of relevant policies. Methods: Using a questionnaire on patients with pneumoconiosis and their influencing factors, 120 patients with pneumoconiosis were randomly selected in Nanjing, Wuxi, Suzhou, Yancheng Vocational Defense Institute or CDC. The rate of outpatients with pneumoconiosis in urban and rural areas and the choice of out-patient hospitals were analyzed. Results: Of the 75 patients with severe pneumoconi-related symptoms such as chest tightness and dyspnea in the first two weeks of the survey, 36 (48.0%) lived in cities and 39 (52.0%) lived in rural areas. Patients with pneumoconiosis who live in urban and rural areas have different aggravating conditions within two weeks. Two weeks of aggravated symptoms in outpatient consultations accounted for36 (48.0%) . Of the 36 patients who used outpatient treatment, rural residents mainly chose 8 people from a hospital and a township health hospital, accounting for 34.8%, while 10 people from urban residents chose a nursing home or nursing home, accounting for 40.0%. The main reason why urban and rural pneumoconiosis patients did not go to the doctor is "conscious symptoms are lighter" and "feel that the doctor is useless." Conclusion: The rate of outpatients with pneumoconiosis in Jiangsu province within two weeks is lower than that of ordinary elderly residents. There may be differences in treatment behavior patterns of urban and rural pneumoconiosis patients.Economic factors have a certain influence on the outpatient treatment behavior of pneumoconiosis patients. The recognition of outpatient service is the main factor affecting the outpatient treatment of pneumoconiosis patients. It is very important to popularize the knowledge of pneumoconiosis and do a good job in propaganda of occupational diseases and health education for pneumoconiosis patients. Focusing on the outpatient treatment of pneumoconiosis patients and making targeted medical policies is very important to standardize and improve the rehabilitation of pneumoconiosis patients.

Abstract
Objective: To investigate the situation where pneumoconiosis patients who should be in hospital are not hospitalized, to analyze the main reasons and influencing factors for their restricted use of hospitalization medical services, and to provide a reference for relevant policy making. Methods: Subjects were sampled in nine provinces, including Zhejiang, Jiangsu, Shandong, and Hebei, using a method that combined stratified sampling and typical sampling, from March 2017 to January 2018. These subjects were patients occupationally diagnosed with pneumoconiosis and patients clinically diagnosed with pneumoconiosis. The questionnaire The health seeking behaviors of pneumoconiosis patients and their influencing factors was used as the survey tool to investigate their health seeking behaviors such as going to the outpatient clinic and being hospitalized. Andersen's Behavioral Model of Health Services Use was used as the analysis model; The χ2 test was used for univariate analysis, and the multivariate logistic regression model was used for multivariate analysis. Results: A total of 1 037 patients with pneumoconiosis were surveyed, with a mean age of 55.9±11.2 years and 67.5% (700/1 037) living in rural areas for a long time. Occupational injury insurance and medical insurance for urban and rural residents were the main insurances used, accounting for 40.9% (424/1 037) and 59.4% (616/1 037) of the cases, respectively. A total of 177 (17.1%) patients were once advised by the doctors to be hospitalized because of pneumoconiosis, while they did not. The proportion of patients who should be in hospital but did not do so among rural patients was significantly higher than that in urban patients (20.1% (141/700) vs 10.7% (36/337) , P<0.05) . Financial difficulties (12.0%, 124/1 037) and self-rated mild symptoms (3.2%, 33/1 037) were the main reasons for not being hospitalized. Model analysis showed that the propensity factor, ability factor, health needs, health seeking behaviors, and self-rated health factor in the Anderson model were all statistically significant (P<0.05) . The main features of high proportion of patients who should be in hospital but did not do so were as follows: personal monthly income below 1 000 RMB (odds ratio[OR]of no income=2.92, 95% confidence interval[CI]: 1.14-7.48; OR of less than 1 000 RMB=3.55, 95%CI: 1.35-9.35) , no occupational injury insurance (OR=2.05, 95%CI: 1.16-3.43) , and concurrent emphysema (OR= 1.98, 95%CI: 1.12-3.50) . Conclusion: Low income, no occupational injury insurance, and concurrent emphy-sema are the main constraining factors for hospitalization services use in pneumoconiosis patients.

Abstract
Objective: To analyze the characteristics of pneumoconiosis patients and the basic status of medical treatment. Methods: Research objects were chosen by stratified sampling method and typical survey method from existing pneumoconiosis patients in China. The survey was carried out from March 2017 to January 2018 in nine provinces including provinces from east, medium and western region in China. Source of pneumoconiosis cases were inpatient cases, outpatient or physical-examined cases and household-investigation cases. The survey mainly included demographic and sociological characteristics, economic status, occupational history and dust exposure history, disease status, work-related injury insurance and social security status and related indicators of pneumoconiosis treatment. Results: Investigated 1037 pneumoconiosis cases which included 186 (19.9%) household-investigation cases, 212 (20.4%) outpatient or physical-examined cases and 639 (61.7%) inpatient cases. Demographic and sociological characteristics, individual monthly income, economic source, occupational history and work-related injury insurance were statistically significant among different source of pneumoconiosis patients (P<0.05) . Among all of the household-investigation cases, there were 74 cases (40.2%) had no income, 117 cases (62.9%) used to work in private enterprises, 36 cases (19.4%) had work-related injuries insurance, 95 cases (51.1%) were at three phase of pneumoconiosis, 108 cases (59.0%) haven't had any drugs for pneumoconiosis. 65 cases (39.4%) haven't went to the clinic, 53 cases (28.5%) hadn't seek medical advice although they needed medical treatment very much. Among all of the outpatient or physical-examined cases, there were 95 cases (46.1%) had no income, 36 cases (17.0%) had work-related injuries Insurance, 139 cases (65.6%) went to the clinic for treatment of pneumoconiosis, 81 cases (38.2%) went to the clinic for more than ten times. Among all the inpatient cases, 310 cases' (49.3%) personal monthly income was above 2000 yuan, 352 cases (55.1%) had work-related injuries Insurance, 588 cases (92.2%) were taking drugs for treatment of pneumoconiosis, 153 canses (24.2%) had hospitalization for than ten times. Conclusion: Household-investigation cases have lower economic conditions, lower rates of Insurance coverage for work-related injuries, severer pneumoconiosis and higher clinical service utilization. Clinical or physical-examined cases have lower economic conditions, lower rates of Insurance coverage for work-related injuries and higher clinical service utilization. Hospitalized cases have better economic conditions, higher rates of insurance coverage for work-related injuries and higher hospitalization service utilization.

Abstract
Objective: To study the main factors that influencing Pneumoconiosis patients' healthcare seeking behaviors. Methods: Conducting a descriptive analysis to analyze the relationship between the annual hospitalization rate and social security status (medical insurance, location of medical insurance, proportion of insurance used for reimbursement of pneumoconiosis, whether there is employment injury insurance at work, whether to apply for compensation after diagnosing pneumoconiosis, whether they receive social assistance and a minimum allowance) , social relationship status of patients (whether there is pneumoconiosis in the family or relatives, whether there is a pneumoconiosis in a friend or a colleague, and whether or not he/she has received financial assistance) , life quality of patients (subjective feelings) and living standard of patients (dietary level) based on data acquired from 120 pneumoconiosis patients. Results: The results of single factor analysis reveal that the location of medical insurance, the proportion of insurance for reimbursement of pneumoconiosis, whether there is employment injury insurance at work, whether to apply for compensation after diagnosing pneumoconiosis are statistically significant in pneumoconiosis patients' hospital utilization ratio (P<0.05) . The place where medical insurance is located is the current place of residence, the reimbursement ratio of medical insurance for pneumoconiosis is listed as 50%-70%, the work unit has medical insurance, those who have not applied for compensation for pneumoconiosis have a higher utilization rate of hospitalization services. The annual hospitalization rate was 73.3%, 80.0%, 60.6%, 63.0%, respectively. Conclusion: The location of patient medical insurance, the proportion of insurance used for reimbursement of pneumoconiosis, whether there is employment injury insurance at work, and whether to apply for compensation after pneumoconiosis are the influencing factors of the patients' annual hospitalization rate.

Abstract
Objective: To explore the value of dual-energy CT-based volumetric iodine-uptake (VIU) in the evaluation of chemotherapy efficacy in advanced gastric cancer. Methods: Inclusion criteria of subjects: (1) without previous systematic therapy; (2) with complete clinical information before and after chemotherapy; (3) without contraindications of chemotherapy. Exclusion criteria of subjects: (1) unfinished duration and times of chemotherapy; (2) unmeasurable primary lesions; (3) poor imaging quality or poor gastric filling. Clinical and image data of 52 patients with advanced gastric cancer who were diagnosed by pathology from gastroscopic biopsy, and needed chemotherapy evaluated by imaging and clinical information in the First Affiliated Hospital of Wenzhou Medical University from February 2017 to February 2018 were collected and analyzed. Of 52 patients, 38 were male and 14 were female with the median age of 65 (31-88) years old. All the patients underwent a dual-energy, dual phase-enhanced CT scanning before chemotherapy and after the third chemotherapy session. The parameters of the lesions measured before and after chemotherapy in portal vein phase were as follows: the maximum diameter (the largest diameter among those measured in the cross-sectional, coronal, and sagittal planes), average CT value (the regions of interest were manually pinpointed under cross-sectional planes with largest diameter of the tumor, which did not include regions less than 2 mm to the edge of the tumor) and VIU (lesion volume × iodine concentration). The change rates of maximum lesion diameter, average CT value and VIU before and after chemotherapy were calculated [(post-chemotherapy parameters-pre-chemotherapy parameters)/ pre-chemotherapy parameters]. The efficacy of chemotherapy was evaluated by RECIST 1.1 (the change of maximum tumor diameter after chemotherapy), Choi (the change of average CT value after chemotherapy) and VIU (the change of VIU after chemotherapy), respectively, which was categorized by complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). Patients with CR, PR, and SD were assigned to the effective group, while those with PD were classified as the ineffective group. Paired t - test or Wilcoxon signed ranks test was used to compare the changes of parameters before and after chemotherapy, whereas Spearman correlation analysis and Kappa test were used for the correlation analysis and the consistency test between the three evaluation criteria (Kappa≥0.75 indicated good consistency). Results: After chemotherapy, the average CT value [(74.01±16.75) HU vs. (81.06±15.87) HU, t=2.202, P=0.030] and median VIU (668.53×10(2) μg vs. 272.52×10(2) μg, Z=4.761, P<0.001) decreased significantly, while the difference of the maximum diameter was not statistically significant [(66.71±34.49) mm vs. (78.45±35.62) mm, t=1.708, P=0.091]. The median change rate of VIU (-53.33%) was greater than that of CT values (-5.75%) with significant difference (Z=-5.408, P<0.001). According to the RECIST 1.1 criteria, 47 patients (90.4%, including 19 with PR and 28 with SD) were effective and 5 patients (9.6%) were ineffective. According to the Choi criteria, 45 patients (86.5%, including 37 with PR and 8 with SD) were effective and 7 patients (13.5%) were ineffective. According to the VIU criteria, 46 patients (88.5%, including 41 with PR and 5 with SD) were effective and 6 patients (11.5%) were ineffective. Efficacy comparison among these three criteria showed no significant difference (χ(2)=0.377, P=0.828). As compared to RECIST 1.1 evaluation, the proportion of PR evaluated by Choi and VIU was significantly higher (χ(2)=16.861, P<0.001), whereas the proportion of SD was significantly lower (χ(2)=24.089, P<0.001). There was no significant difference in the proportions of PR and SD between VIU and Choi criteria (χ(2)=0.887, P=0.346). Consistency and correlation analysis showed that the VIU and Choi evaluation criteria presented the highest consistency and correlation (Kappa=0.912, P<0.001; r=0.916, P<0.001). Conclusion: VIU is a feasible parameter for the evaluation of chemotherapy efficacy in advanced gastric cancer, and may be more sensitive than the evaluation criteria based on maximum diameter or change of CT value in the tumor.

Abstract
Objective: To analyze the occurrence features of adverse events following immunization (AEFI) of Seasonal Influenza Vaccines (InfV) used in China, 2015-2018 influenza season. Methods: InfV (including concurrent administered with other vaccines) AEFI data were collected through the Chinese national AEFI information system during 2015.9.1-2018.8.31 (excluding Chinese Hong Kong, Macao and Taiwan data). The vaccine lot release data were collected from National Institutes for Food and Drug Control published database. Time periods of three influenza season were 2015.9.1-2016.8.31, 2016.9.1-2017.8.31, 2017.9.1-2018.8.31. The vaccines used and included in this analysis were trivalent inactivated influenza vaccine (IIV3)-Split, IIV3-Split (Children) and IIV-subnit. The incidence of AEFI were calculated (per 100 000 release doses), and epidemiological characteristic were analyzed using descriptive methodology. Results: A total of 8 464 InfV AEFIs were collected in 2015-2018 influenza season from National AEFI Information System, in which 5 646 were IIV3-split, with the rate of 10.64/100 000 release doses, 2 818 were IIV3-split (Children), with the rate of 9.355/100 000 release doses. The most common symptom was fever (axillary temperature ≥37.1 ℃) within vaccine reactions, with a number of 6 207 cases. In which, there were 3 554 cases with fever (axillary temperature ≥38.6 ℃) and the estimated reporting rate was 4.274/100 000 release doses. In all rare vaccine reactions, the most common diagnosis was anaphylactic rash(442, 0.531/100 000 release doses) and angioedema (70, 0.084/100 000 release doses). Even the rates of serious rare vaccine reactions were low, febrile Convulsion (27, 0.032/100 000 release doses) and Henoch-Schönlein Purpura(HSP) (21, 0.025/100 000 release doses) were relatively common in serious rare vaccine reactions during the study period. Conclusion: The estimated rate of rare vaccine reactions related toInfV was relatively low. In all vaccine reactions, fever was the most common symptoms. The most common diagnosis of non-serious rare vaccine reaction were anaphylactic rash and angioedema. The incidence of serious rare vaccine reactions was low.

Abstract
Objective: To analyze the changing epidemiological characteristics of hepatitis E cases in China, in order to promote in preventing and controlling hepatitis E. Methods: Data of hepatitis E and outbreaks reported through national notifiable diseases reporting system were analyzed from 2004 to 2017, but data of Hongkong, Macau and Taiwan were not included. Data of hepatitis E were divided into three phases as 2004-2007, 2008-2011 and 2012-2017, representing eight years before, four years before and years after the postmarketing of hepatitis E vaccine. Linear regression was used for analyzing the trend of hepatitis E, improved muster method was used for analyzing the seasonal intensity. Results: From 2004 to 2017, 329 519 hepatitis E cases were reported and the annual incidence were increasing from 1.27/100 000 to 2.10/100 000 (t=6.87, P<0.001). The concentrations of hepatitis E during 2004-2007, 2008-2011 and 2012-2017 were 17.43, 16.06, 11.17, respectively, with low seasonal intensity. Number of cases reported by Jiangsu, Guangdong and Zhejiang accounted for 31.54% of national cases. The incidence were lower in central (1.45/100 000) and western (1.11/100 000) region than that in eastern region (2.67/100 000), but were increasing continuously. There was an increasing trend of incidence with growing ages (t=7.85, P<0.001). The incidence was higher than 2/100 000 among cases aged ≥40, and was the highest (5.22/100 000) in the age group of 65-69 years old. Farmers, retired persons, houseworkers and unemployees accounted for 67.46% of total cases. A total of 7 outbreaks were reported, among which 3 were in nursing homes. Conclusion: The incidence of hepatitis E in central and western regions were increasing continuously and the surveillance should be strengthened. There was higher risk among middle-aged population, farmers and nursing homes, so strategy for immunization among those population was in great need.

Abstract
Objective: To investigate the diagnostic value of extracellular volume (ECV) imaging by magnetic resonance imaging for liver fibrosis of hepatitis B. Methods: A retrospective analysis was recruited in patients with chronic hepatitis B, who underwent liver surgery from April to October 2017 for pathological evaluation of liver tissues, and all patients underwent Gd-EOB-DTPA-enhanced T1 mapping to calculate the liver ECV score. The correlation between ECV and staging of hepatic fibrosis and inflammatory activity were compared to clarify the diagnostic value of staging of fibrosis. Results: 66 patients were enrolled in this study. Concerning the staging of liver fibrosis, there were 13, 4, 13, 10, and 26 cases with F0, F1, F2, F3 and F4 stages, respectively. ECV values had high interobserver consistency (correlation coefficient 0.860). The ECV difference between different stages of liver fibrosis was statistically significant (F = 15.02, P < 0.001). There was a significant positive correlation between ECV and fibrosis stage (r = 0.622, P < 0.001), and weak correlation with inflammatory activity (r = 0.332, P = 0.007). Fibrosis staging was an independent factor influencing ECV (P < 0.001). The area under the receiver operator characteristic curve for the diagnosis of liver fibrosis staging F≥1, F≥3 and F4 were 0.760, 0.846 and 0.873, respectively. The diagnostic sensitivity and specificity were 64.15%, 92.31%, 77.78%, 80.00% and 88.46, 72.50%, respectively. Conclusion: MRI-ECV imaging has great value for staging hepatic fibrosis of hepatitis B, and it can provide an effective method for diagnosis, staging, and evaluating the curative effect of fibrosis.

Abstract
Objective: To explore the application value of endoscope in probing the chronic wound with sinus tract in clinic. Methods: Twenty-eight chronic wounds with sinus tracts from 27 patients conforming to the inclusion criteria admitted to Outpatient Department of Wound Healing Center of Ruijin Hospital from December 2017 to March 2018 were investigated in a prospective and self-controlled trial. After being cleaned, the diameter of the opening of sinus tract was measured with a rule. A probe was used to measure the depth of a sinus tract according to the touch from the probe extremity in operation, and to measure the depth of a sinus tract that could be observed with naked eyes with the help of a pair of hemostatic forceps. Five minutes later, a probe was inserted deeply into the sinus tract to measure the depth under the endoscopic view combined with touch from the probe extremity in operation. Afterwards, the sinus tract was observed with endoscope, and the depth of the tract which could be observed under the endoscopic view was measured using a probe inserted deeply into the sinus tract. After completion of the above exploration, the sinus tract was infused with contrast agent Omnipaque 350 and scanned by computed tomography (CT) later to obtain its depth. The following indicators were calculated: the ratio of the depth of the sinus tract measured by CT to the diameter of the opening of the sinus tract (hereinafter referred to as the depth/diameter ratio of the sinus tract), the deviation rate comparing the depth of the sinus tract measured by conventional method (measured by probe only) and by endoscope (measured by probe under the endoscope view) with the depth of the sinus tract measured by CT (hereinafter referred to as the deviation rate of the measured depth of the sinus tract), the deviation rate comparing the depth of the sinus tract that could be observed measured by conventional method and by endoscope with the depth of the sinus tract measured by CT (hereinafter referred to as the deviation rate of the depth of the sinus tract that could be observed). Data were processed with paired t test. Pearson correlation analysis was applied to analyze the correlation between the depth/diameter ratio of the sinus tract and the deviation rate of the measured depth of the sinus tract and the deviation rate of the depth of the sinus tract that could be observed by conventional method and by endoscope. Results: The depth/diameter ratio of the sinus tract of this group of wounds was 1-32 (8±7). The deviation rate of the measured depth of the sinus tract and the deviation rate of the depth of the sinus tract that could be observed by conventional method were (19±14)% and (79±18)%, respectively, both obviously larger than (9±9)% and (25±25)% by endoscope (t=3.837, 13.626, P<0.01). Positive correlation existed between the depth/diameter ratio of the sinus tract and the deviation rate of the measured depth of the sinus tract by conventional method, and between the depth/diameter ratio of the sinus tract and the deviation rate of the depth of the sinus tract that could be observed by conventional method and by endoscope (r=0.514, 0.585, 0.651, P<0.01). However, there was no obvious correlation between the depth/diameter ratio of the sinus tract and the deviation rate of the measured depth of the sinus tract by endoscope (r=0.113, P>0.05). Conclusions: Compared with the conventional method, application of endoscope is able to get more accurate data of chronic wounds with sinus tracts and observe the wounds with wider range.

Abstract
Objective: Percutaneous radiofrequency thermocoagulation (RFT) of the Gasserian ganglion is an effective treatment for refractory trigeminal craniofacial pain.In the present study, we assessed the feasibility of accessing the Gasserian ganglion through the foramen ovale with neuronavigation guidance in the patients of trigeminal craniofacial pain. Method: We retrospectively analyzed forty-four patients with type Ⅰ trigeminal neuralgia who had undergone percutaneous RFT treatment in our hospital from June 2014 to December 2016.The patients were divided into fluoroscopy group and navigation group according to the intraoperative guiding manners for foramen ovale cannulation.We compared groups in terms of the duration of the whole RFT procedure and times of intraoperative fluoroscopy.We also analyzed the immediate and late outcome accessing by Barrow Neurological Institute (BNI) pain scale, as well as the complication rates in groups. Result: There were 32 patients in the fluoroscopy group and 12 in the navigation group.The duration of the surgical procedure in navigation group was less than that in fluoroscopy group (46±12 min versus 67±16 min, P=0.00), and times of intraoperative fluoroscopy was reduced (6.3±2.2 versus 1.3±1.6, P=0.00). The learning curve of navigation-aid RFT was not steep in the present study overall.There was no significant difference between groups regarding pain reduction at the immediate (P=0.07) or late follow-up (P=0.400) time points.However, the rate of pain reduction to BNI-Ⅰ grade was greater in navigation group (P=0.026). No significant difference in the complication rate between both groups, and no serious complications were observed in the both groups. Conclusion: Neuronavigation may be encouraged in trigeminal Gasserian ganglion RFT with better operating efficiency and less radiation exposure.The immediate and late therapeutic effects for craniofacial pain control were positive, whereas further studies are necessary.

Abstract
Objective: To detect of the components and concentration of the metals and metalloids in the lavage fluid of whole-lung lavage (WLL) of the cases of pneumoconiosis, and analyze the characteristics, and explore the method to sample and process the samples of bronchoalveolar lavage fluid (BAL) . Methods: The samples of urine and serum of three cases of pneumoconiosis were collected before WLL, and the samples of BAL were collected during the WLL from the left and right lungs according to the sequence of four pressured gas flow and five negative pressure drainage. Each of 10ml original samples of WLL was collected firstly, and the left was centrifuged to acquire all the sediment samples and each of 10 ml samples from the centrifuge clear liquids, The components and concentration of the metals and metalloids in the samples were measured by Inductively Coupled Plasma mass spectrometer (ICP-MS) . Results: The average volume of BAL from unilat-eral lung for 3 patients was 10 758.3±1518 ml, and the average recovery rate was 89.7%. The average dry weight of sediment samples of BAL of three cases of pneumoconiosis was 0.292 gram with the right lung sam-ples slightly higher than the left lung samples. The detectable elements from the samples included Barium (Ba) , Strontium (Sr) , Calcium (Ca) , Magnesium (Mg) , Manganum (Mn) , Ferrum (Fe) , Cuprum (Cu) , Zinc (Zn) , Kalium (K) , Natrium (Na) , Selenium (Se) , Silicon (Si) and Uranium (U) . Each of concentration dis-tributions of these elements were not normal. Except for Cuprum, Selenium and Uranium, the concentrations of the other ten elements in the supernatant samples, mixture samples and sediments samples were statistical-ly different with the nonparametric test of Kruskal-Wallis. The concentrations of Natrium, Kalium and Barium in supernatant samples were higher, while the others in precipitation samples were higher. The concentration of elements in the sample from the right lung was slightly higher than that from the left lung, but there was no statistically significant difference (P>0.05) . There were statistical difference in term of element concentration of precipitates samples before and after pressured gas flow (P<0.05) . The concentration of K、Ca、Mg、Si and Se in se-rum, urine, supernatant and sediment samples had a good correlation. The correlation coefficient of Silicon between serum and precipitation was 0.676 and that between urine and precipitation was 0.524. Conclusion: The concentra-tions of the metals and metalloid in sediment samples were more stable than that of supernatant and mixture samples. The sampling of one-side lung lavage fluid was representative in the detection of metals and metalloid in the BAL. It was the best time for sampling sediment from the BAL after the first pressured gas flow among the WLL.

Abstract
Fast visible imaging of the lower divertor from above is used to study the structure and dynamics of lobes induced by resonant magnetic perturbations (RMPs) in Edge-Localized Mode (ELM) suppression experiments in DIII-D. The best compromise between the amount of light and sharp imaging was obtained using emission at 601 nm from Fulcher band molecular deuterium. Multiple spatially resolved peaks in the D2 emission, taken as a proxy for the particle flux, are readily resolved during RMPs, in contrast to the heat flux measured by infrared cameras, which shows little spatial structure in ITER-like conditions. The 25 mm objective lens provides high spatial resolution (2-4 mm/pixel) from the centerpost to the outer shelf over 40° toroidally that overlaps the field of view of the IRTV that measures the divertor heat flux, allowing direct comparison in non-axisymmetric discharges. The image is coupled to a Phantom 7.3 camera using a Schott wound fiber bundle, providing high temporal resolution that allows the lobe dynamics to be resolved between ELMs and across ELM suppression onset. These measurements are used to study the heat and particle flux in 3D magnetic fields and to validate models for the plasma response to RMPs.

Abstract
Objective: To investigate the safety and efficacy of needle-tract assisted standard percutaneous nephrolithotomy (PCNL) for the treatment of complicated upper urinary tract calculi. Methods: The clinical data of 1 562 patients with complicated upper urinary calculi who received standard PCNL from December 2013 to December 2017 at Department of Urology, the First Affiliated Hospital of Xiamen University were retrospectively analyzed. There were large residual stones in 256 patients through B-ultrasound exploration after standard PCNL, could't be detected with nephoscope in standard PCNL tracts. 16 F mini PCNL tract were established in 120 cases for treatment of residual stones, while needle-tract were established in order to guide nephroscope to find residual stones in 126 cases. Needle-tract were transferred to 16 F mini PCNL tract for treatment of residual stones in 10 patients if these residual stones could't be detected through needle-tract. Operation time, change of hemoglobin level after operation, incidence of postoperative complications, time of hospitalization and rate of stone clearance were measured in two groups. The statistical methods used included t test, Wilcoxon rank sum test, and χ2 test. Results: There were 1 to 3 mini tracts (M(QR): 1(1)) established in the mini tracts group and 1 to 7 needle-tracts (M(QR): 3(2)) established in the needle-tract group (Z=-10.57, P=0.000). Compared with mini tract group, the operation time ((62.0±18.0) minutes vs. (84.0±15.5) minutes, t=10.242, P=0.000), hospitalization time ((4.40±0.86) days vs. (5.20±0.81) days, t=7.570, P=0.049), hemoglobin dropped ((1.31±0.47) g/L vs. (2.74±0.63) g/L, t=20.12, P=0.000), and incidence of postoperative complications (7.9% (10/126) vs. 19.2% (23/120), χ2=6.674, P=0.01) of needle-tract group were lower, while postoperative stone clearance rate was higher (89.7% vs. 76.7%, χ2=7.497, P=0.006). No perioperative severe complications such as pleural injury, pneumatothorax, perforation of renal, trauma of abdominal organ occurred in two groups. Conclusion: Needle-tract assisted standard PCNL for the treatment of complicated upper urinary calculi can significantly improve stone clearance rate, reduce operation time, decrease risk of kidney and surrounding organs damage.

Abstract
A novel type of surface eroding thermocouple (SETC) has been tested and demonstrated in the small angle slot (SAS) divertor of DIII-D for fast local heat flux measurements. The thermojunction of the SETC is formed between two thin (10 μm) ribbons, which are filed over to create microfiber junctions. These thermocouples are able to be exposed directly to the plasma at surface temperatures exceeding 2000 °C and are capable of sub-10 ms time resolution. Before installation in SAS, the SETCs were exposed in the lower DIII-D divertor during L-mode and H-mode discharges, from which results are presented. In preliminary tests, SETCs proved to be a qualified diagnostic to accurately measure both the intra-edge localized mode (ELM) and inter-ELM heat flux during H-mode shots with high frequency ELMs (hundreds of Hz) and to resolve heat flux profiles during strike point sweeps. The heat fluxes measured by using SETCs are consistent with the heat fluxes measured by using IR cameras and Langmuir probes. These new diagnostic capabilities will complement the existing IR camera measurements and will be of particularly significant value to measure surface heat flux in the SAS divertor or other regions where the IR camera lacks line of sight.
