Abstract
Objective: To analyze the efficacy and safety of first-line treatment with an anti-CD38 monoclonal antibody regimen for primary plasma cell leukemia (pPCL). Methods: Patients diagnosed with pPCL from December 1st, 2018 to July 26th, 2023, receiving first-line treatment of anti-CD38 monoclonal antibody-based regimens across multiple centers including Peking University People's Hospital, Fuxing Hospital of Capital Medical University, Qingdao Municipal Hospital, Shengjing Hospital of China Medical University, Handan Central Hospital, the First Affiliated Hospital of Harbin Medical University, the Fourth Hospital of Hebei Medical University and General Hospital of Ningxia Medical University were consecutively included. A total of 24 pPCL patients were included with thirteen being male and eleven being female. The median age [M(Q1, Q3)] was 60 (57, 70) years. Patients were grouped according to peripheral blood plasma cell (PBPC) percentage [5%-19% (n=14) vs ≥20% (n=10)]. Last follow-up date was September 26th, 2023. The median follow-up period was 9.1 (4.2, 15.5) months. Patients' data related with clinical baseline characteristics, efficacy, survival and safety were retrospectively collected. Cox proportional hazards regression model was used to analyze risk factors associated with survival. Results: Among 24 pPCL patients, 16 (66.7%) patients had anemia at diagnosis, 13(54.2%) patients had thrombocytopenia, 8 (33.3%) patients had a baseline estimated glomerular filtration rate (eGFR)<40 ml·min-1·(1.73m2)-1, 13 (54.2%) patients had elevated lactate dehydrogenase (LDH) levels. The median PBPC percentage was 16% (8%, 26%) . Fluorescence in situ hybridization testing indicated that patients harboring 17p deletion, t(4;14) or t(14;16) were 6 (25.0%), 4 (16.7%) and 4 (16.7%), respectively. The overall response rate was 83.3% (20/24). The median progression-free survival (PFS) was 20.5 (95%CI: 15.8-25.2) months, and the median overall survival (OS) was not reached. Estimated 1-year and 2-year PFS and OS rates were 75.0% and 89.1%, 37.5% and 53.4%, respectively. The median PFS and OS for patients with PBPC percentages 5%-19% and≥20% were not reached and 20.5 (95%CI:15.7-25.3) months, 17.8 months and not reached, respectively. There was no significant statistical difference of PFS and OS between two groups (all P>0.05). Multivariate Cox regression analysis showed that 1p32 deletion was the risk factor associated with PFS (HR=7.7, 95%CI: 1.1-54.9, P=0.043). Seventeen patients (70.8%) developed grade 3-4 hematologic toxicities. Twelve patients (50.0%) developed grade 3-4 thrombocytopenia. Sixteen patients (66.7%) developed infection. All hematologic toxicities and infections were improved after supportive treatment. Conclusion: First-line treatment with anti-CD38 monoclonal antibody-based therapy for pPCL is effective and safe.

Abstract
Objective: To analyze the epidemic characteristics of mumps in people aged 0-14 years in Jiangxi Province and the vaccination situation of mumps-containing vaccines (including mumps vaccines) from 2015 to 2022 to provide a scientific basis for the prevention and control of mumps epidemic in Jiangxi Province. Methods: The mumps epidemic situation and mumps vaccination data in Jiangxi Province from 2015 to 2022 were obtained from Chinese Disease Prevention and Control Information System and Jiangxi Immunization Program Information System and were analyzed using descriptive epidemiological methods. The chi-square test, cluster analysis, and Cochran-Armitage trend test were used for statistical analysis. Results: From 2015 to 2022, a total of 40 734 cases of mumps were reported in people aged 0-14 in Jiangxi Province, with an annual average reported incidence rate of 53.69/100 000, and the peak of incidence occurred in aged 6-7 years group, and the reported incidence rate was 86.43/100 000. The high incidence seasons in 2015-2019 were summer and winter, and there was no significant high incidence season in 2020-2022. Mumps outbreaks mainly occurred in Shangrao, Ganzhou, and Ji'an, and the outbreak sites were mainly reported primary schools. From 2015 to 2019, the 1-year group was the primary age group for vaccination against mumps, while from 2020 to 2021, it was 0 and 1-year groups. Conclusions: From 2015 to 2022, the incidence of mumps in the population aged 0-14 in Jiangxi Province showed a downward trend, and the peak of incidence occurred in age group 6-7 years. It is suggested to continue to strengthen the coverage rate of 2 doses of mumps vaccination for school-age children and, simultaneously, strengthen the monitoring and prevention of mumps in key places to avoid outbreaks.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases in children and adolescents. NAFLD ranges in severity from isolated hepatic steatosis to nonalcoholic steatohepatitis (NASH), wherein hepatocellular inflammation and/or fibrosis coexist with steatosis. Circulating microRNA (miRNA) levels have been suggested to be altered in NAFLD, but the extent to which miRNA are related to NAFLD features remains unknown. This analysis tested the hypothesis that plasma miRNAs are significantly associated with histological features of NAFLD in adolescents. AIM To investigate the relationship between plasma miRNA expression and NAFLD features among adolescents with NAFLD. METHODS This study included 81 adolescents diagnosed with NAFLD and 54 adolescents without NAFLD from the Teen-Longitudinal Assessment of Bariatric Surgery study. Intra-operative core liver biopsies were collected from participants and used to characterize histological features of NAFLD. Plasma samples were collected during surgery for miRNA profiling. A total of 843 plasma miRNAs were profiled using the HTG EdgeSeq platform. We examined associations of plasma miRNAs and NAFLD features using logistic regression after adjusting for age, sex, race, and other key covariates. Ingenuity Pathways Analysis was used to identify biological functions of miRNAs that were associated with multiple histological features of NAFLD. RESULTS We identified 16 upregulated plasma miRNAs, including miR-193a-5p and miR-193b-5p, and 22 downregulated plasma miRNAs, including miR-1282 and miR-6734-5p, in adolescents with NAFLD. Moreover, 52, 16, 15, and 9 plasma miRNAs were associated with NASH, fibrosis, ballooning degeneration, and lobular inflammation, respectively. Collectively, 16 miRNAs were associated with two or more histological features of NAFLD. Among those miRNAs, miR-411-5p was downregulated in NASH, ballooning, and fibrosis, while miR-122-5p, miR-1343-5p, miR-193a-5p, miR-193b-5p, and miR-7845-5p were consistently and positively associated with all histological features of NAFLD. Pathway analysis revealed that most common pathways of miRNAs associated with multiple NAFLD features have been associated with tumor progression, while we also identified linkages between miR-122-5p and hepatitis C virus and between miR-199b-5p and chronic hepatitis B. CONCLUSION Plasma miRNAs were associated with NAFLD features in adolescent with severe obesity. Larger studies with more heterogeneous NAFLD phenotypes are needed to evaluate miRNAs as potential biomarkers of NAFLD.

Abstract
Objective: To predict and analyze the incidence trend of mumps using the Autoregressive integrated moving average model (ARIMA) in Jiangxi Province. Methods: The ARIMA was used to model the number of mumps cases per month from 2015 to 2019 in Jiangxi Province. The number of mumps cases in 12 months was predicted and was compared with the actual reported cases in 2020, 2021, and 2022, respectively. Results: The optimal model was ARIMA (0,2,1)(1,2,0)12. The predicted number of cases was significantly higher than that reported in 2020, 2021 and 2022. The number of reported cases of mumps in 2020, 2021, and 2022 decreased by 54.02%, 63.40%, and 66.09% compared with the forecast. Conclusions: From 2020 to 2022, the reported incidence of mumps in Jiangxi Province was significantly lower than the predicted incidence. Considering that it was related to non-drug intervention measures and changes in immunization strategies, it was suggested to strengthen mumps surveillance further to better cope with the epidemic situation of mumps.

Abstract
Objectives: Microvascular obstruction (MVO) is a specific cardiac magnetic resonance (CMR) imaging feature in patients with acute myocardial infarction. The purpose of this study was to elucidate the predictive value of MVO in left ventricular adverse remodeling after primary percutaneous coronary intervention (PCI) in patients with acute ST-elevation myocardial infarction (STEMI). Methods: A total of 167 patients with STEMI undergoing primary PCI in the Chinese PLA General Hospital from 2016 to 2020 were enrolled in this prospective cohort study, the average age of study patients was 57±10 years old, with 151 males (90.4%) and 16 females (9.6%). The patients were divided into the MVO group (n=81) and non-MVO group (n=86) according to the presence or absence of MVO on CMR imaging, respectively. The primary endpoint of the study was the occurrence of left ventricular adverse remodeling, which was defined as an increase in left ventricular end diastolic volume (LVEDV) by >20% at 6 months after primary PCI compared with the baseline. Patients who completed follow-up were diagnosed as left ventricular adverse remodeling or no left ventricular adverse remodeling according to CMR. The baseline data, perioperative data, and related data of end points were compared between the MVO group and non-MVO group. Finally, the predictive value of MVO in left ventricular adverse remodeling was calculated by receiver operating characteristic curve analysis. Results: In the baseline data, preoperative thrombolysis in myocardial infarction (TIMI) flow (χ2=13.74, P=0.003) and postoperative TIMI flow (χ2=14.87, P=0.001) were both obviously decreased in the MVO group. After 6 months of follow-up, the incidence of left ventricular adverse remodeling in the MVO group was significantly higher than that in the non-MVO group [37.0%(27/73) vs. 18.9%(14/74), χ2=5.96, P=0.015]. The left ventricular end systolic volume at 6 months post infarction in the MVO group was significantly larger than that in the non-MVO group [(94±32) vs. (68±20) ml, t=-5.98, P<0.001], as well as the LVEDV [(169±38) vs. (143±29) ml, t=-4.74, P<0.001]. Receiver operating characteristic curve showed that the area under the curve of MVO size for predicting left ventricular adverse remodeling was 0.637. Conclusion: The risk of left ventricular adverse remodeling is significantly increased in patients with MVO after primary PCI for acute STEMI.

Abstract
Objective: The purpose of this study was to assess the safety and efficacy of a second allogeneic hematopoietic stem cell transplantation (allo-HSCT) with reduced-intensity conditioning (RIC) in patients with hematological malignancies who had relapsed after the first allo-HSCT. Methods: Between April 2018 and June 2021, 44 patients with hematological malignancies (B-ALL 23, T-ALL/T-LBL 4, AML15, and MDS 2) were enrolled and retrospectively examined. Unrelated donors (n=12) or haploidentical donors (n=32) were used. Donors were replaced in all patients for the second allo-HSCT. Hematological and immunological germline predisposition genes and hematopoietic and immune function tests were used to select the best-related donor. Total body irradiation (TBI) /fludarabine (FLU) -based (n=38), busulfan (BU) /FLU-based (n=4), total marrow irradiation (TMI) /FLU-based (n=1), and BU/cladribine-based (n=1) were the RIC regimens used. For graft versus host disease (GVHD) prevention, cyclosporine, mycophenolate mofetil, short-term methotrexate, and ATG were used. Eighteen (40.9%) of 44 patients with gene variations for which targeted medications are available underwent post-transplant maintenance therapy. Results: The median age was 25 years old (range: 7-55). The median interval between the first and second HSCT was 19.5 months (range: 6-77). Before the second allo-HSCT, 33 (75%) of the patients were in complete remission (CR), whereas 11 (25%) were not. All patients had long-term engraftment. The grade Ⅱ-Ⅳ GVHD and severe acute GVHD rates were 20.5% and 9.1%, respectively. Chronic GVHD was found in 20.5% of limited patterns and 22.7% of severe patterns. CMV and EBV reactivation rates were 29.5% and 6.8%, respectively. Hemorrhage cystitis occurred in 15.9% of cases, grade Ⅰ or Ⅱ. The 1-yr disease-free survival (DFS), overall survival (OS), and cumulative recurrence incidence (RI) rates of all patients were 72.5% (95% CI, 54.5%-84.3%), 80.6% (95% CI, 63.4%-90.3%), and 25.1% (95% CI, 13.7%-43.2%), respectively, with a median follow-up of 14 (2-39) months. There were eight deaths (seven relapses and one infection). The rate of non-relapse mortality (NRM) was only 2.3%. The CR patients' 1-yr RI rate was significantly lower than the NR patients (16.8% vs 48.1%, P=0.026). The DFS rate in CR patients was greater than in NR patients, although there was no statistical difference (79.9% vs 51.9%, P=0.072). Univariate analysis revealed that CR before the second allo-HSCT was an important prognostic factor. Conclusion: With our RIC regimens, donor change, and post-transplant maintenance therapy, the second allo-HSCT in relapsed hematological malignancies after the first allo-HSCT is a safe and effective treatment with high OS and DFS and low NRM and relapse rate. The most important factor influencing the prognosis of the second allo-HSCT is the patient's illness condition before the transplant.

Abstract
OBJECTIVE To investigate the diversity and composition of microflora in laboratory-reared Aedes albopictus at different developmental stages and larval habitat waters. METHODS The larval habitat waters and different developmental stages of laboratory-reared A. albopictus were collected, and the V3 and V4 regions of the bacterial 16S rRNA gene were sequenced using Illumina Miseq next-generation sequencing. The abundance and diversity of the microflora were examined using alpha diversity index in A. albopictus at different developmental stages, and the difference in the microflora compositions was compared in A. albopictus at different developmental stages using principal component analysis (PCA). In addition, the species composition and relative abundance of microflora in A. albopictus at different developmental stages were described using histograms and Venn diagrams. RESULTS A total of 16 phyla, 30 classes, 72 orders, 129 families and 224 genera of bacteria were detected in larval habitat waters and different developmental stages of A. albopictus. The highest bacterial diversity was seen in larval A. albopictus, with Chao index of 125.20 ± 30.48 and Shannon diversity index of 2.04 ± 0.39, which were comparable to those (Chao index of 118.52 ± 15.07 and Shannon diversity index of 2.15 ± 0.30) in larval habitat waters (t = 0.35 and -0.41, both P values > 0.05). The bacterial abundance and evenness were significantly greater in female adults than in male adults (Chao index: 42.50 ± 3.54 vs. 18.50 ± 2.13, t = 8.23, P < 0.05; Shannon diversity index: 1.25 ± 1.67 vs. 0.50 ± 0.05, t = 6.00, P < 0.05). Proteobacteria, Bacteroidota, Actinobacteriota and Finnicutes were four common phyla of bacteria at each developmental stage of A. albopictus, with Proteobacteria dominated at the pupal stage (90.36%), Bacteroidota dominated at the adult stage (46.01% in female adults and 86.11% in male adults), and Actinobacteriota dominated at the larval stage (32.10%). Elizabethkingia and Rahnella 1 were common dominant genera of bacteria at each developmental stage of A. albopictus, with Rahnellal as the major component at the pupal stage (87.56%), Elizabethkingia as the main component at the adult stage (46.01% in female adults and 86.11% in male adults, respectively), and Microbacteria as the dominant bacterial genus at the larval stage (12.11%). In addition, Delftia, Elizabethkingia, Romboutsia, Serratia, Rahnella 1, Enterococcus and Microbacterium were common genera of bacteria at each developmental stage of A. albopictus, with Edaphobaculum dominated at the larval stage (17.54%) and Sphingobacterium dominated in larval habitat waters (13.93%). CONCLUSIONS There are differences in the composition of symbiotic bacteria at different developmental stages of A. albopictus; however, similar microflora diversity is maintained at the phylum level. The microflora diversity is comparable in larvae and larval habitat waters of A. albopictus.

Abstract
Objective: To explore a modified CT scoring system, its feasibility for disease severity evaluation and its predictive value in coronavirus disease 2019 (COVID-19) patients. Methods: This study was a multi-center retrospective cohort study. Patients confirmed with COVID-19 were recruited in three medical centers located in Beijing, Wuhan and Nanchang from January 27, 2020 to March 8, 2020. Demographics, clinical data, and CT images were collected. CT were analyzed by two emergency physicians of more than ten years' work experience independently through a modified scoring system. Final score was determined by average score from the two reviewers if consensus was not reached. The lung was divided into 6 zones (upper, middle, and lower on both sides) by the level of trachea carina and the level of lower pulmonary veins. The target lesion types included ground-glass opacity (GGO), consolidation, overall lung involvement, and crazy-paving pattern. Bronchiectasis, cavity, pleural effusion, etc., were not included in CT reading and analysis because of low incidence. The reviewers evaluated the extent of the targeted patterns (GGO, consolidation) and overall affected lung parenchyma for each zone, using Likert scale, ranging from 0-4 (0=absent; 1=1%-25%; 2=26%-50%; 3=51%-75%; 4=76%-100%). Thus, GGO score, consolidation score, and overall lung involvement score were sum of 6 zones ranging from 0-24. For crazy-paving pattern, it was only coded as absent or present (0 or 1) for each zone and therefore ranging from 0-6. Results: A total of 197 patients from 3 medical centers and 522 CT scans entered final analysis. The median age of the patients was 64 years, and 54.8% were male. There were 76(38.8%) patients had hypertension and 30(15.3%) patients had diabetes mellitus. There were 75 of the patients classified as moderate cases, as well as 95 severe cases and 27 critical cases. As initial symptom, dry cough occurred in 170 patients, 134 patients had fever, and 125 patients had dyspnea. Reparatory rate, oxygen saturation, lymphocyte count and CURB 65 score on admission day varied among patients with different disease severity scale. There were 50 of the patients suffered from deterioration during hospital stay. The median time consumed for each CT by clinicians was 86.5 seconds. Cronbach's alpha for GGO, consolidation, crazy-paving pattern, and overall lung involvement between two clinicians were 0.809, 0.712, 0.678, and 0.906, respectively, showing good or excellent inter-rater correlation. There were 193 (98.0%) patients had GGO, 147 (74.6%) had consolidation, and 126(64.0%) had crazy-paving pattern throughout clinical course. Bilateral lung involvement was observed in 183(92.9%) patients. Median time of interval for CT scan in our study was 7 days so that the whole clinical course was divided into stages by week for further analysis. From the second week on, the CT scores of various types of lesions in severe or critically patients were higher than those of moderate cases. After the fifth week, the course of disease entered the recovery period. The CT score of the upper lung zones was lower than that of other zones in moderate and severe cases. Similar distribution was not observed in critical patients. For moderate cases, the ground glass opacity score at the second week had predictive value for the escalation of the severity classification during hospitalization. The area under the receiver operating characteristic curve was 0.849, the best cut-off value was 5 points, with sensitivity of 84.2% and specificity of 75.0%. Conclusions: It is feasible for clinicians to use the modified semi-quantitative CT scoring system to evaluate patients with COVID-19. Severe/critical patients had higher scores for ground glass opacity, consolidation, crazy-paving pattern, and overall lung involvement than moderate cases. The ground glass opacity score in the second week had an optimal predictive value for escalation of disease severity during hospitalization in moderate patients on admission. The frequency of CT scan should be reduced after entering the recovery stage.

Abstract
The smoking cessation rate of 1 314 people at high risk of lung cancer in the area of lung cancer screening and early diagnosis and early treatment in Sichuan Province increased from 22.37% at baseline to 41.78% after screening (χ²=227.97, P<0.001), and the smoking amount of persistent smokers decreased from 20 cigarettes per day to 15 cigarettes per day (t=11.76, P<0.001). Those with positive results in lung cancer screening were more likely to quit smoking or continue to quit smoking. Male, younger age or lower education level would increase the risk of continuous smoking or relapse (P<0.05).

Abstract
Objective: To explore the application value of heparin binding protein (HBP) in the diagnosis of severe infection in patients with silicosis. Methods: A prospective study was conducted on 150 patients with silicosis in the pneumoconiosis department of the General Hospital of Xuzhou Mining Group from January 2017 to March 2018. Among them, 100 were severely infected with silicosis and 50 were non-infected with silicosis. 30 patients were selected in the same period of physical examination as the control group. HBP, C-reactive protein (CRP) , procalcitonin(PCT) , white blood cell count (WBC) , neutrophil percentage, and absolute neutrophil count(ANC) were detected in all participants. Using the receiver operating characteristic curve(ROC) to analyze the diagnostic value of indicator above in patients with different stages of severe silicosis infection. Results: Plasma HBP levels in patients with severely infected silicosis group[(50.39±35.64) ng/ml] were higher than those in the non-infected group[(10.71±1.47) ng/ml] and the control group[(9.24±1.83) ng/ml] (P<0.05) , and with the increase of silicosis stages, there is an increasing trend (P<0.05). The ROC curve showed that the AUC of HBP in the patients with severe silicosis in the first, second, and third stages were 0.932, 0.977, and 0.964, which were higher than those of WBC, CRP, and PCT. Correlation analysis showed that HBP was positively correlated with WBC, CRP and PCT (r=0.711, 0.359, 0.729, P<0.01). Conclusion: HBP has high diagnostic efficacy in the diagnosis of severe infections in patients with silicosis, which may become a clinical screening indicator for severe infections in patients with silicosis and an auxiliary examination indicator for the stage of silicosis patients.

Abstract
Objective: To investigate the clinical and coagulation characteristics in patients with critical Coronavirus disease 2019 (COVID-19) and acro-ischemia. Methods: The retrospective study included 7 critical COVID-19 patients with acro-ischemia in an intensive care unit (ICU) in Wuhan, from Feb 4 to Feb 15, 2020. The clinical and laboratory data before and during the ICU stay were analyzed. Results: The median age of 7 patients was 59 years and 4 of them were men. Three patients were associated with underlying comorbidities. Fever, cough, dyspnea and diarrhea were common clinical symptoms. All patients had acro-ischemia presentations including finger/toe cyanosis, skin bulla and dry gangrene. D-dimer, fibrinogen and fibrinogen degradation product (FDP) were significantly elevated in most patients. Prothrombin time was prolonged in 4 patients. D-dimer and FDP levels progressively elevated consistent with COVID-2019 exacerbation. Four patients were diagnosed with disseminated intravascular coagulation (DIC) . Low molecular weight heparin (LMWH) was administrated in 6 patients, which reduced D-dimer and FDP rather than improved clinical symptoms. Five patients died finally and the median time from acro-ischemia to death was 12 days. Conclusions: Coagulation parameters should be monitored closely in critical COVID-2019 patients. The timing and protocol of anticoagulation therapy are still under investigation based on more clinical data.

Abstract
Objective: To investigate the clinical and coagulation characteristics of the critical Coronavirus disease 2019 (COVID-19) patients with acro-ischemia in the intensive care unit (ICU). Methods: The retrospective study included 7 critical COVID-19 patients with acro-ischemia in a single center in Wuhan, from Feb 4 to Feb 15, 2020. The clinical and laboratory data before and during the ICU stay were analyzed. Results: The median age of 7 patients was 59 years and 4 of them were men. 3 of them were associated with underlying comorbidities. Fever, cough, dyspnea and diarrhea were common clinical symptoms. All patients had acro-ischemia presentations including finger/toe cyanosis, skin bulla and dry gangrene. D-dimer, fibrinogen and fibrinogen degradation product (FDP) were significantly elevated in most patients. Prothrombin time (PT) were prolonged in 4 patients. D-dimer and FDP levels increased progressively when COVID-2019 exacerbated, and 4 patients were diagnosed with definite disseminated intravascular coagulation (DIC). 6 patients received low molecular weight heparin (LMWH) treatment, after which their D-dimer and FDP decreased, but there was no significant improvement in clinical symptoms. 5 patients died finally and the median time from acro-ischemia to death was 12 days. Conclusions: The existence of hypercoagulation status in critical COVID-2019 patients should be monitored closely, and anticoagulation therapy can be considered in selected patients. More clinical data is needed to investigate the role of anticoagulation in COVID-2019 treatment.

Abstract
Objective: To investigate the level of the core knowledge and related factors of cancer prevention and treatment among residents in the upper gastrointestinal cancer screening areas of Sichuan Province in 2018. Methods: From April to May 2018, a total of 1 386 residents from Chaotian District of Guangyuan, Enyang District of Bazhong, Nanjiang County of Bazhong, Cangxi County of Guangyuan, Shehong County of Suining, Yilong County of Nanchong, Xichong County of Nanchong and Xuanhan County of Dazhou were recruited in this study. A questionnaire survey was conducted to collect basic demographic characteristics and the knowledge of cancer prevention and treatment. The level of the core knowledge of cancer prevention and treatment of different population was analyzed. A multivariate linear regression model was performed to analyze the related factors. Results: In total, 80.9% (1 120) of all subjects was 25-64 years old and 48.0% (665) were male. The total number of questions answered by the subjects was 18 018, of which 12 147 were known, and the overall awareness rate among the respondents was 67.42%. The female respondents, respondentsaged 65 years old and over, with junior college education or above, and worked in government institutions had a good performance of the core knowledge (P<0.05), about 70.11% (6 571/9 373), 69.23% (387/559), 76.05% (6 327/8 320), and 77.09% (5 602/7 267) respectively. The results of multivariate linear regression showed that the older the age [β=0.871 (95%CI: 0.623-1.119)], the higher the educational level [β=0.741 (95%CI: 0.540-0.943)], the more questions respondents could know; compared with the workers in government organization and institution, workers in enterprise [β=-2.913 (95%CI:-3.499--2.327)], farming workers [β=-0.635 (95%CI:-1.175--0.095)] and other occupation people [β=-1.126 (95%CI:-1.663--0.589)] could know fewer questions. Conclusion: In 2018, the level of the core knowledge of cancer prevention and treatment among residents in upper gastrointestinal cancer screening areas of Sichuan Province was relatively high. Age, education level and occupation were relevant factors.

Abstract
OBJECTIVE To explore the sensitivity of Culex pipiens pallens to common chemical insecticides in the southwestern region of Shandong Province, so as to provide a theoretical basis for the development of reasonable and effective mosquito control measures. METHODS The resistance of Cx. pipiens pallens larvae to 5 chemical insecticides, such as cypermethrin, deltamethrin, DDVP, propoxur, and acetofenate were tested by using the WHO biological test method in 2018, and the co-toxicity coefficients after compounding the above-mentioned insecticides were tested by using a drug compounding method. RESULTS The resistance indexes of Cx. pipiens pallens to cypermethrin, deltamethrin, DDVP, propoxur, and acetofenate in 3 cities were 144.43-557.54, 118.17-445.33, 6.44-19.00, 2.37-8.10, and 0.88-2.98, respectively, and expect the difference between the DDVP resistances of Cx. pipiens pallens in Jining City and Heze City was not statistically significant (P > 0.05), all the other differences were statistically significant (all P < 0.05). The synergistic coefficients of cypermethrin + DDVP, cypermethrin + propoxur, DDVP + acetofenate, and propoxur + acetofenate were 199.58 - 456.95, 190.56 - 292.37, 123.32 - 319.24, and 192.31 - 367.32, respectively. The lower synergism was observed by using the mixture of DDVP + propoxur (synergistic coefficient: 99.87-108.36) . CONCLUSIONS After decades of chemical control, Cx. pipiens pallens in the southwestern region of Shandong Province has produced different degrees of resistance to common chemical insecticides. Therefore, comprehensive control measures should be taken to control mosquito breeding and prevent the development of insecticide resistance.

Abstract
The occurrence of hepatocellular carcinoma (HCC) is a multistep development process through precancerous lesions. A precancerous lesion of HCC is classified into hepatocyte dysplasia at the cytological level and dysplastic nodules at the histological level, and the corresponding lesion subtypes have different risks of canceration. Pathology is the "gold standard" for the diagnosis of early stage HCC and its precancerous lesions. However, it also faces many difficulties and challenges, such as the accumulation of experience in the pathological diagnosis, the understanding and grasp of key points of histopathological diagnosis and differential diagnosis, the combination application of immune and molecular diagnostic markers, and many others. This article briefly discusses the key points of pathological features and differential diagnosis of precancerous lesions of HCC.

Abstract
In this study, the involvement of aluminum-based drinking water treatment residual (DWTR) as substrate in floating treatment wetland (FTW) to enhance its treatment performance was firstly proposed and trialed. A laboratory scale DWTR-FTW fed with synthetic wastewater containing COD, nitrogen (N), phosphorus (P) and mineral salts was operated in three stages of unplanted (1-30 days), planted (31-60 days) and aerated (61-135 days) modes. The results showed that the average removal rates of COD, total nitrogen (TN), total phosphorus (TP) in stage 3 were 88%, 85%, and 90.2%, respectively, indicating the outstanding purification performance of DWTR-FTW in comparison of traditional FTWs. The embedded DWTR enriches the biomass and robustly adsorbs P, while aeration supplies sufficient dissolved oxygen for the microorganism. The results revealed that 7.022 g P was accumulated in DWTR, which is 400 times higher than that in sediment and plants during the experimental period, reflecting that DWTR adsorption is the major P removal pathway in DWTR-FTW. Overall, DWTR-FTW could significantly remove pollutants, especially P, and provide an alternative pathway to enhance purification performance of FTW.

Abstract
Objectives: To assess the diagnostic values of latex immunoturbidimetric assay (LIA) and particle immunofiltration assay (PIFA) for heparin-induced thrombocytopenia (HIT) . Methods: Samples from 94 patients with suspected HIT from May 2016 to July 2018 in our hospital were prospectively analyzed by the two immunoassays. Their medical records and further follow-up data were also collected and analyzed by our hematologists to make the 4Ts scores and confirm the diagnosis of HIT, respectively. Performance characteristics of the two immunoassays were assessed, including sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) . Their post-test probabilities (PTP) were also calculated based on the 4Ts score. Results: Among 94 cases, 15 (16.0%) had a positive HIT, including 6 of 37 (16.2%) with an intermediate, and 9 of 15 (60.0%) with a high 4Ts score. PIFA operating characteristics were: sensitivity 100.0% (15/15) , specificity 51.9% (41/80) , PPV 28.3% (15/53) , NPV 100.0% (41/41) . The positive PTP in intermediate and high 4Ts score group were 28.7% and 75.7%, respectively, while negative PTP were all 0. At manufacturers' cutoffs, LIA operating characteristics were: sensitivity 66.7% (10/15) , specificity 94.9% (75/79) , PPV 71.4% (10/14) and NPV 93.8% (75/80) . The positive and negative PTP in intermediate 4Ts score group were 71.8% and 6.3%, while 95.2% and 34.4% in high 4Ts score group, respectively. Receiver operating characteristic (ROC) analysis manifested that LIA was preferable than PIFA, and combining the 2 assays together was significantly better than single test. Conclusions: 4Ts score is still an important tool for the diagnosis of HIT. Combining clinical score with heparin/PF4 antibody assay can increase the accuracy of confirming or excluding HIT. Although PIFA is inferior to LIA in the diagnostic value, its user friendliness and 100% NPV have major advantages. Combining the 2 assays together can achieve a higher diagnostic value.

Abstract
Recently, graphene decorated with various inorganic nanoparticles, such as Pt, Au, Ag, TiO2 and Fe3O4, among which Ag nanocomposites are good candidates for electronics, optics, electrochemistry and catalysis. However, preparation techniques for Ag nanoparticles/carbon matrix hybrids require tedious multi-step processes often involving toxic reducing agents/high temperatures which is not viable for scalable production. Here, a facile, one step and eco-friendly chemical co-reduction route was utilized to synthesis of a new nanocomposites by Ag nanoparticle anchored on reduced graphene oxide (rGO) at ambient temperature and combined first principles theoretical analyze their interfacial adsorption behavior, is reported. In this way, graphene oxide (GO) and Ag+ simultaneously reduced by thiourea dioxide (TD) without using any additional reduced reactants. Results indicated that GO was successfully reduced to rGO and well-dispersed Ag nanoparticles with sizes of 6-7 nm, anchored on the surface of rGO sheets. Reduction mechanism was attributed to the synergistic effect of its hydrolysis products in aqueous media. The experiment and theoretical calculation results obtained demonstrate this method to be applicable to the synthesis of other metals on rGO sheets in order to improve wettability and interfacial bonding between rGO and metal and may possibly find various forthcoming medicinal, industrial and technological applications.

Abstract
Objective: To evaluate the actual efficacy of cervical cancer and precancerous lesions screening approaches in real-world regions with different economic levels in China. Methods: The demonstrative application and effect evaluation of cervical cancer screening program were conducted in 21 hospitals nationwide from 2015 to 2018. Multi-stage sampling method was adopted to divide the country into 7 large areas according to geographical location. Two to four screening sites of two types of cancer (cervical cancer and breast cancer) were selected in each area, and the grassroots screening sites were implemented under the guidance of superior hospitals. In rural areas, women were initially screened using cytology, human papillomavirus (HPV) testing and visual inspection. The women with positive cytology or visual inspection were referred for colposcopy, and the women with positive HPV infection were randomly referred for reflex cytology or visual inspection, or direct colposcopy examination. In urban areas, women were primarily randomized into cytology or HPV testing groups. The women with abnormal cytology or positive HPV 16/18 infection were directly referred for colposcopy examination, whereas the women with positive infection of the other 12 high-risk subtypes of HPV were referred for reflex cytology or colposcopy. All of recruited women would be follow-up and screened by the baseline screening techniques in the third year while the positive women underwent colposcopy examination. The positive rates, referral rates, the detection rates of grade 2 and above of cervical intraepithelial neoplasia (CIN 2+ ) were compared. Results: A total of 63 931 women were recruited at the baseline. Among them, 11 rural sites included 33 823 women: 15 577, 11 157 and 7 089 women were screened by HPV testing, visual inspection via acetic acid or Lugol's iodine (VIA/VILI) and cytology, respectively. Additionally, 30 108 women were from 10 urban sites: 9 907 and 20 201 women were screened by cytology and HPV subtyping, respectively. The HPV positive rate for urban women was 9.34%, whereas that for rural women was 12.53%. The abnormal rate of cytology for urban women was 5.63%, and that for rural women was 4.24%. The positive rate of VIA/VILI in the rural women was 12.25% Furthermore, the detection rate of CIN2+ at the baseline was 0.56%, and that was statistically higher in HPV-positive group than cytology-positive group (P<0.05). Conclusions: All of screening sites completed the baseline screening tasks as expected. The prevalence of HPV infection is higher in rural women than urban women. The performance of HPV testing is better than cytology for detecting CIN2+ cases. This real-world demonstration study provides evidences for cervical cancer prevention and control in different regions.

Abstract
AIM To retrospectively identify clinicopathological and radiological characteristics that could be independent predictors of epidermal growth factor receptor (EGFR) exon 19 and 21 mutation in surgically resected lung adenocarcinomas in a cohort of Asian patients. MATERIALS AND METHODS Demographics, histopathology data, and preoperative chest computed tomography (CT) images were evaluated retrospectively in 471 surgically resected lung adenocarcinomas. A total of 24 CT descriptors were assessed. Univariate analyses and multivariate logistic regression analyses were performed to identify independent predicted factors of harbouring EGFR mutations. RESULTS EGFR mutations were existed in 252 (53.5%) of 471 patients, and associated with 11 clinicoradiological features. For the model with both clinical and radiological features, the independent predictors of harbouring EGFR mutation were small maximum diameter (≤3.9 cm), non-smokers, micropapillary pattern, pleural retraction, vascular convergence, and absence of solid pattern. The area under the receiver operating characteristic (ROC) curve (AUC) was 0.784. Multivariable logistic regression analysis indicated that non-smokers, vascular convergence, and absence of solid pattern were important independent predictors of EGFR exon 19 mutation, while non-smokers and vascular convergence were independent predictors of EGFR exon 21 mutation. The AUCs were 0.807 and 0.794, respectively. A lepidic growth pattern appeared more frequently in exon 21 mutant tumours than in exon 19 mutant group (p<0.001). CONCLUSION CT imaging features of lung adenocarcinomas in combination with clinical variables could be used to prognosticate EGFR mutation status. The separate analysis of EGFR exon 19 or 21 mutation could further improve diagnostic performance.

Abstract
Objective: To investigate the effectiveness and safety of the thoracic paravertebral block(TPVB) in the post postanesthesia care unit(PACU) for patients suffered moderate to severe pain after Video-Assisted Thoracoscopic Surgery(VATS). Methods: 78 atients who complained moderate to severe pain on arrival to PACU after VATS were randomly assigned into two groups: thoracic paravertebral block treatment group(P group) and sufentanil treatment group(S group). The VAS Pain score at rest and movement, heart rate, blood pressure, and pulse oximetry 1 hour after treatment and duration of patients staying in the PACU after treatment were recorded. VAS Pain score at rest and on coughing at 8, 24 and 48 hours after treatment were closely monitored. Sufentanil comsumption, patient satisfaction and related complications were also recorded. Results: A successful TPVB was achieved in all patients in P group without puncture related complications. The VAS pain scores at rest and on coughing 1 hour, 8 hours, 24 hours and 48 hours after treatment in P group were significantly lower than the patients in S group. Systolic blood pressure 1 hour after treatment in P group was also lower than the patients in S group(118mmHg±14mmHg vs 128 mmHg±14 mmHg, P=0.021). SPO2 1 hour after treatment in P group was much higher than the patients in S group(95%±3% vs 92%±4%, P=0.015). The duration of patients staying in the PACU after treatment in both groups were similar. Sufentanil comsumption, rate of vomiting and nausea was significantly less and satisfaction was better in P group than thoses in S group. Conclusion: In the postanesthesia care unit, TPVB could provide effective and safe analgesia therapy for patients suffered from moderate to severe pain after VATS.

Abstract
Ti6Al4V (TC4) alloy has long been used as a bone interfacing implant material in dentistry and orthopedics due to its excellent biocompatibility and mechanical properties. The performance of TC4 can be further tailored by altering its grain structures. In this study, by means of sliding friction treatment (SFT), a nano-grained (NG) surface layer with an average grain size of ≤100 nm on the topmost surface was successfully generated on coarse-grained (CG) TC4 alloy sheet. It was shown that the NG surface possessed notably enhanced corrosion resistance in physiological solution compared to the CG surface, due to the formation of thicker and denser passive film facilitated by surface nanocrystallization. Additionally, the NG surface with stronger hydrophilicity favorably altered the absorption of anchoring proteins such as fibronectin (Fn) and vitronectin (Vn) that can mediate subsequent osteoblast functions. The in vitro results indicated that the NG surface exhibited remarkable enhancement in osteoblast adherence, spreading and proliferation, and obviously accelerated the osteoblast differentiation as compared to CG surface. Moreover, the NG surface also demonstrated good hemocompatibility. These findings suggest that SFT can endure bio-metals with advanced multifunctional properties for biomedical applications.

Abstract
Since March 2013, China had experienced five seasonal epidemics related to Avian influenza A (H7N9). An unprecedented outbreak of H7N9 epidemic started from September 2016, with 730 cases reported till June 30(th) 2017, in mainland China that caused profound influences on both social development and health of the people. As an emerging infectious disease, information on pathogenic characteristics, transmission patterns and other epidemiological features of H7N9 virus somehow remained unclear. Data from previous studies suggested that the live poultry market (LPM) seemed to have served as main places where H7N9 virus got originated, mutated, spread and thus infected the human beings. Hence, closure of LPMs was suggested a major measure to control and prevent H7N9 epidemics in China. However, the effectiveness of different ways of LPM closures on H7N9 epidemics had been controversial. This study systemically summarized the effects of different ways of LPM closures on H7N epidemics from previous studies, aiming to provide references for developing a better program on H7N9 control and prevention in the country.

Abstract
Objective: To find the differences in PM(2.5) exposure level in the context of four commuting modes (by walk, bicycle, bus and subway) in Guangzhou. Methods: The PM(2.5) exposure assessment was carried out from January to December 2015 in Guangzhou. PM(2.5) was measured by using SidePak individual dust meter (AM510, TSI Inc. USA) with time interval of 1 minute. Our measurement was taken on Monday, Wednesday, Friday and Sunday in the second week of each month and the samples were collected in the morning (07:00-09:00), afternoon (11:00-13:00) and evening (17:00-19:00). Results: A total of 284 air samples during walking, 281 air samples during bicycle riding, 278 air samples in bus, and 280 air samples in subway were collected. The median PM(2.5) concentrations exposed during walking, during bicycle riding, in bus and in subway were 38.4, 38.6, 23.3 and 24.1 μg/m(3), respectively, which were positive correlated with exposure concentration in fixed surveillance sites. The exposure level was lowest in summer, and highest in winter. The median of one-way exposure level to PM(2.5) from high to low were as follows: 21.0 μg for bicycle riding, 20.1 μg for walking, 5.1 μg for taking bus and 2.6 μg for taking subway. The season and time specific one-way exposure levels to PM(2.5) of four commuting modes were consistent. Conclusions: The exposure level to PM(2.5) was obviously higher during walking and bicycle riding than that in bus and subway. The exposure level to PM(2.5) during walking was higher than that during bicycle riding, in bus and in subway.

Abstract
A genome-wide association study (GWAS) was conducted on 15 milk production traits in Chinese Holstein. The experimental population consisted of 445 cattle, each genotyped by the GGP (GeneSeek genomic profiling)-BovineLD V3 SNP chip, which had 26 151 public SNPs in its manifest file. After data cleaning, 20 326 SNPs were retained for the GWAS. The phenotypes were estimated breeding values of traits, provided by a public dairy herd improvement program center that had been collected once a month for 3 years. Two statistical models, a fixed-effect linear regression model and a mixed-effect linear model, were used to estimate the association effects of SNPs on each of the phenotypes. Genome-wide significant and suggestive thresholds were set at 2.46E-06 and 4.95E-05 respectively. The two statistical models concurrently identified two genome-wide significant (P < 0.05) SNPs on milk production traits in this Chinese Holstein population. The positional candidate genes, which were the ones closest to these two identified SNPs, were EEF2K (eukaryotic elongation factor 2 kinase) and KLHL1 (kelch like family member 1). These two genes could serve as new candidate genes for milk yield and lactation persistence, yet their roles need to be verified in further function studies.

Abstract
Objective: To evaluate the efficacy and safety of maintenance therapy with reduced dose of rhTPO in the patients with primary immune thrombocytopenia (ITP) who attained stable platelet (PLT) counts after daily administration of rhTPO. Methods: Treatment was started with a daily administration of rhTPO (300 U/kg) for 2 consecutive weeks. Patients who attained stable PLT≥50×10(9)/L were enrolled to maintenance therapy starting with every other day administration of rhTPO, then adjusted dose interval to maintain platelet count (30-100) ×10(9)/L. Results: A total of 91 eligible patients were enrolled. Fourteen patients discontinued the study due to noncompliance (12/14) and investigator decision (2/14) . Among 77 patients who completed the study, 38 patients with the administration of rhTPO at every other day or less could maintain PLT≥30×10(9)/L for 12 weeks. The percentage of patients with a platelet response (PLT≥30×10(9)/L) at 4(th) week, 8(th) week and 12(th) week of maintain therapy was 92.6% (63/68) , 82.7% (43/52) and 85.0% (34/40) , respectively. Median platelet counts remained in the range of (70-124) ×10(9)/L. The overall incidence of rhTPO-related adverse events was 7.7%. All the adverse events were generally mild. Conclusion: Extending the dose interval of rhTPO is feasible to maintain stable platelet count in the patients with ITP, but the optimal dose interval is uncertain and might vary with individuals.

Abstract
Objective: To investigate the efficacy of general anesthesia with epidural anesthesia and postoperative epidural analgesia in terms of pain relief and post-operative functional recovery. Methods: Ninety-six patients were randomly assigned to general anesthesia and intravenous analgesia group (GI) or general anesthesia combined with epidural anesthesia and epidural analgesia group (GE). Demographic and operative data, postoperative VAS pain scores, gastrointestinal function, postoperative hospital stays, general complications were assessed prospectively. Results: (1) The postoperative VAS scores of patients in the group GE at 2, 24, 48, and 72 hours were significantly lower than those in the group GI. (2) Compared with the group GI, the patients in group GE had earlier postoperative flatus and a shorter postoperative hospital stay (8.4 ± 2.5 vs 10.0 ± 3.2, P=0.012 8). Conclusion: General anesthesia combined with epidural anesthesia and postoperative epidural analgesia could provide better pain relief, enhance early rehabilitation and reduce the duration of hospital.

Abstract
Objective:To evaluate the postoperative pain degree on OSAHS patients following UPPP, analyze the pain characteristic during seven consecutive days, and discuss the mechanism. To observe the analgesia effect by using flubiprofen axetil. Finally making a comprehensive understanding about UPPP perioperative period and providing more choices about analgesia treatment.Method:Fifty-five patients who underwent UPPP in the First Hospital of China Medical University were divided into analgesia group(n=30)and control group(n=25).Normal saline 50 ml+ flubiprofen axetil 100 mg was used bid for pain relief in analgesia group during seven days following operation, and normal saline 50ml was used in control group.A visual analog scale(VAS) was used for measuring mean pain intensity each day during the period from operative day to the post-operative 7th day,scores were recorded. Continuous changes about pharynx pain were observed and VAS pain scores were compared betweenanalgesia groupand control group. Result:VAS pain scores were the highest on the operative day and the post-operative 1st day, median (interquartile range) was 7(5.5-8.25),7(6-8)respectively,then decreased gradually. The most significantly decrease happened on the post-operative 2nd and 5th day(P<0.01). Pain scores in analgesia group were most significantly lower than control group from the operative day to the post-operative 4th day(P<0.01), were lower during the post-operative 5th and 6th day(P<0.05),no difference on the post-operative 7th day. Conclusion:The most painful period following UPPP is from the operative day to the post-operative 1st day, then pain decreases gradually. The pain reduces significantly on the post-operative 2nd and 5,6th day.Surgical trauma, in flammatory reaction and suture pulling may be the reason of pain. Flubiprofen axetil effectively reduces pain and the suggested analgesia period is from the operative day to the post-operative 4th-6th day.

Abstract
Objective: To estimate the effect of daily diurnal temperature range (DTR) on mortality in different areas in China. Methods: A time series study using the data collected from 66 areas in China was conducted, and Meta-analysis was used to analyze the estimates of associations between DTR and daily mortality. Modifying effects of extremely low and high DTR-mortality relationship by season and socioeconomic status (SES) were also evaluated respectively. Cumulative excess risk (CER) was used as an index to evaluate the effects. Results: The information about 1 260 913 registered deaths were collected between 1 January 2006 and 31 December 2011, we found the relationship between extreme DTR and mortality was non-linear in all regions and the exposure-response curve was J-shaped. In central and south areas of China, the result indicated the obvious acute effect of extremely high DTR, and the mortality effect in central area (CER=5.1%, 95% CI: 2.4%-7.9%) was significant higher than that in south area (CER=4.5%, 95% CI: 1.7%-7.3%). Regarding to the modification of seasons, the cumulative mortality effect of DTR in cold season (CER=5.8%, 95%CI: 2.5%-9.2%) was higher than that in hot season (CER=3.1%, 95%CI: 1.1%-5.1%). Generally, deaths among the elderly (≥75 years) were associated more strongly with extremely high DTR. Conclusions: The mortality effects of extremely DTR in different areas and seasons showed different characteristics, that in central area and in cold season it was significantly stronger. After modified by season and SES, DTRs were the greatest threat to vulnerable population, especially to the elderly (≥75 years). Therefore, more attention should be paid to vulnerable groups and protection measures should be taken according to the local and seasonal conditions.

Abstract
Internet data is introduced into public health arena under the features of fast updating and tremendous volume. Mining and analyzing internet data, researchers can model the internet-based surveillance system to assess the distribution of health-related events. There are two main types of internet-based surveillance systems, i.e. active and passive, which are distinguished by the sources of information. Through passive surveillance system, information is collected from search engine and social media while the active system gathers information through provision of the volunteers. Except for serving as a real-time and convenient complementary approach to traditional disease, food safety and adverse drug reaction surveillance program, Internet-based surveillance system can also play a role in health-related behavior surveillance and policy evaluation. Although several techniques have been applied to filter information, the accuracy of internet-based surveillance system is still bothered by the false positive information. In this article, we have summarized the development and application of internet-based surveillance system in public health to provide reference for a better surveillance program in China.

Abstract
This study assessed the performance and diversity of microbial communities in multi-stage sub-surface flow constructed wetland systems (CWs). Our aim was to assess the impact of configuration on treatment performance and microbial diversity in the systems. Results indicate that at loading rates up to 100gBOD5/(m(2)·day), similar treatment performances can be achieved using either a 3 or 4 stage configuration. In the case of phosphorus (P), the impact of configuration was less obvious and a minimum of 80% P removal can be expected for loadings up to 10gP/(m(2)·day) based on the performance results obtained within the first 16months of operation. Microbial analysis showed an increased bacterial diversity in stage four compared to the first stage. These results indicate that the design and configuration of multi-stage constructed wetland systems may have an impact on the treatment performance and the composition of the microbial community in the systems, and such knowledge can be used to improve their design and performance.

Abstract
Osteosarcoma represents an aggressive type of bone malignancy that poses a significant health threat. The objective of the current study was to analyze the effect and mechanism of dihydroartemisinin (DHA) on the proliferation, metastasis and apoptosis of human osteosarcoma cells. A gradient concentration of DHA (15, 25 and 35 μmol.L-1) was used to stimulate the cells, along with control and Dimethyl sulfoxide (DMSO). The phenotypic outcomes were characterized using MTT assay, clone formation assay, Hoechst 33258 staining assay, luciferase reporter plasmid assay, Western blot and wound healing assay. In addition, IBM SPSS Statistics 18.0 software was applied for statistical analysis and all experimental data were expressed as mean ± s.d. Analysis of variance (ANOVA) was applied to compare the differences among multiple groups. Our results demonstrated that DHA inhibited the proliferation and metastasis of osteosarcoma cells and promoted the apoptosis in the cytomorphosis.

Abstract
Individualized treatment rules recommend treatments on the basis of individual patient characteristics. A high-quality treatment rule can produce better patient outcomes, lower costs and less treatment burden. If a treatment rule learned from data is to be used to inform clinical practice or provide scientific insight, it is crucial that it be interpretable; clinicians may be unwilling to implement models they do not understand, and black-box models may not be useful for guiding future research. The canonical example of an interpretable prediction model is a decision tree. We propose a method for estimating an optimal individualized treatment rule within the class of rules that are representable as decision trees. The class of rules we consider is interpretable but expressive. A novel feature of this problem is that the learning task is unsupervised, as the optimal treatment for each patient is unknown and must be estimated. The proposed method applies to both categorical and continuous treatments and produces favourable marginal mean outcomes in simulation experiments. We illustrate it using data from a study of major depressive disorder.

Abstract
A model simulating the effluent nitrogen (N) concentration of treated animal farm wastewater in a pilot on-site constructed wetland (CW) system, using dewatered alum sludge cake (DASC) as wetland substrate, is presented. The N-model was developed based on the Structural Thinking Experiential Learning Laboratory with Animation software and is considering organic nitrogen, ammonia nitrogen (NH3) and nitrate nitrogen (NO3-N) as the major forms of nitrogen involved in the transformation chains. Ammonification (AMM), ammonia volatilization, nitrification (NIT), denitrification, plant uptake, plant decaying and uptake of inorganic nitrogen by algae and bacteria were considered in this model. pH, dissolved oxygen, temperature, precipitation, solar radiation and nitrogen concentrations were considered as forcing functions in the model. The model was calibrated by observed data with a reasonable agreement prior to its applications. The simulated effluent detritus nitrogen, NH4-N, NO3-N and TN had a considerably good agreement with the observed results. The mass balance analysis shows that NIT accounts for 65.60%, adsorption (ad) (11.90%), AMM (8.90%) followed by NH4-N (Plants) (5.90%) and NO3-N (Plants) (4.40%). The TN removal was found 52% of the total influent TN in the CW. This study suggested an improved overall performance of a DASC-based CW and efficient N removal from wastewater.

Abstract
We conducted a cohort study to investigate whether 3 potential single nucleotide polymorphisms (SNPs) in the xeroderma pigmentosum complementation group G (XPG) gene could predict the survival of advanced non-small cell lung cancer (NSCLC) patients treated with platinum-based doublet chemotherapy. We enrolled 262 patients with histologically confirmed NSCLC between November 2007 and December 2008 in this study. The 3 SNPs (rs2296147T>C, rs2094258C>T, and rs873601G>A) were genotyped using polymerase chain reaction-restriction fragment length polymorphism analysis. Older age, Eastern Cooperative Oncology Group performance score ≥2 and higher disease stage were associated with shorter survival. In the Cox proportional hazard model, patients carrying the rs2296147 TT genotype and the T allele had a significantly reduced risk of developing progressive disease or dying from NSCLC. The HRs (95%CI) were 0.31 (0.13-0.73) and 0.44 (0.24-0.83) for progression-free survival and 0.32 (0.14-0.71) and 0.54 (0.32-0.98) for overall survival, respectively. Moreover, advanced NSCLC patients carrying the rs2094258 GG and the G allele had a significantly decreased risk of developing progressive disease. The HRs (95%CI) for the rs2094258 GG genotype and the G allele were 0.35 (0.16-0.80) and 0.45 (0.23-0.86) for overall survival, respectively. We suggest that the rs2296147 and rs2094258 polymorphisms could be used as surrogate markers, leading to individualization of NSCLC treatment strategies.

Abstract
Adaptation in the overall codon usage pattern of West Nile virus (WNV) to that of two hosts was estimated based on the synonymous codon usage value (RSCU). Synonymous codon usage biases for the beginning coding sequence of this virus were also analyzed by calculating the usage fluctuation for each synonymous codon along the target region (the first 270 codon sites of the whole coding sequence of WNV). Adaptation of WNV to Anopheles gambiae regarding the overall codon usage revealed a mixture of synonymous codon usage patterns between this virus and its vector. Regarding the adaptation of WNV to its dead-end host and codon usage, although a mixture of overall codon usage patterns exists, the number of codons with reversed tendency codon usage is lower than that between the virus and its vector. In addition, some codons with low RSCU values for this virus are highly selected in the beginning translation region of WNV, while codons with low RSCU values in this region tend to pair with tRNAs present in low abundance in the host, suggesting that highly selected codons in a specific region in the beginning region of WNV are, to some degree, influenced by the corresponding low tRNA abundance of hosts to regulate the translation speed of the WNV polyprotein.

Abstract
We investigate the potential association of miR-149C>T and miR-499A>G polymorphisms and the risk of hepatocellular carcinoma (HCC). A matched case-control study of 152 cases and 304 controls were conducted. The miR-149C>T and miR-499A>G genotypes were analyzed using duplex polymerase chain reaction with restricted fragment length polymorphism. HCC patients were more likely to be smokers and drinkers, have hepatitis B and C virus infections, and a family history of cancer. The miR-149 CC genotype was associated with a reduced risk of HCC, while the miR-499 GG genotype was associated with an increased risk of HCC. However, we did not find that the miR-149 CC and miR-499 GG genotypes were associated with risk of HCC, and no interaction was found between miR-149C>T and miR-499A>G polymorphisms and hepatitis B virus infection. In conclusion, the miRNA-149C>T and miR-499A>G polymorphisms were found to play an important role for HCC risk in China. This finding could be useful in identifying people at high risk for the disease for early intervention.

Abstract
INTRODUCTION White grape pomace is not subject to maceration, keeping nearly all polyphenols of grapes, so they represent important sources of bioactive compounds such as proanthocyanidins. Preparation of plant polyphenol extracts is usually performed using raw material powder. However, the fine particles make the further extraction procedure steps more difficult. OBJECTIVE To study the effect of mechanical treatments on extraction yields and anti-oxidant activity from different parts of white grape pomace. METHODS Skins, stems and seeds were isolated from the pomace of white winemaking process. Sequential solvent extraction of polyphenols, first using 80% methanol in water followed by 75% acetone in water, was carried out on both entire and milled (< 1 mm) grape solids; extraction on seed polyphenols was also performed in its squashed form. The phenolic content of each extract was verified by spectrometric and HPLC methods and its anti-oxidant activity was evaluated by the 1,1-diphenyl-2-picrylhydrazyl test. RESULTS More total polyphenols can be extracted from each milled tissue than from its entire form. Seeds present the highest total phenol, oligomeric and polymeric proanthocyanidin content, and similar extraction yield was found between milled and squashed tissues. The HPLC analysis showed no difference in extraction yield of low-molecular-weight proanthocyanidins between milled and entire stems. Anti-oxidant activity showed a positive correlation with total phenol content, galloyled oligomers and polymeric proanthocyanidins. CONCLUSION The use of entire stems and squashed seeds for solvent extraction of polyphenols makes manipulation simpler and more cost-efficient, providing similar extraction yields to using their powdery forms.

Abstract
Even to date, Oral squamous cell carcinoma (OSCC), which is one of the most common malignancies worldwide, is still a major public health problem. The cellular mechanisms underlying development of OSCC are poorly understood. Lipid rafts-associated proteins not only serve as a docking platform for protein sorting and membrane trafficking, but also coordinate signaling molecules at cell membrane to mediate intracellular responses, which makes them susceptible to be subverted by cancer cells. Although Flotillin-1 has been discovered for decades, its potential role in OSCC development is largely unknown. In current study, we demonstrate that Flotillin-1 is highly expressed in OSCC cell lines compared to normal oral epithelial cells. Modulation of Flotillin-1 expression via transfection with Flotillin-1 expression vector or shRNA showed that Flotillin-1 has a clearly positive impact on cell growth and motility in KB and/or Tca8113 cell lines. These observations were further supported by using mice or zebrafish tumor xenograft models. Mechanistic study indicated that Flotillin-1 expression activates NF-κB signaling pathway by enhancing phosphorylation of p65 and IκBα, and translocation of p65 into nucleus. Furthermore, inhibition of EGFR by AG1478 markedly repressed Flotillin-1-induced activation of NF-κB signaling pathway. Our studies suggested that Flotillin-1 plays an important role in OSCC development, and might be a potential therapeutic target for OSCC.

Abstract
This paper presents an integrated model of substrate clogging in a vertical flow constructed wetland (VFCW). The model simulates the reduction of pore space in the wetland substrate due to combined influences of various physical, biogeochemical and plant-related processes. A series of experiments based on laboratory-scale VFCWs were conducted to examine and measure key parameters related to clogging of the wetland substrate during operation under different conditions. The model was then validated using data collected from the experiments. The results showed that the model was able to replicate the clogging phenomenon as observed in the experiments, in particular, the characteristic clogging time. The model also predicted well individual contributions to clogging by accumulated inert suspended solids, microbial biomass and plant root materials during the wetland operation. Although the validation was based on the laboratory data, the results indicated that the model describes well the processes underlying the clogging and has the potential to become a tool for assessing the performance of prototype CWs in relation to clogging at both the design and operation stages.

Abstract
Bacterial fruit blotch (BFB) is a devastating disease caused by Acidovorax citrulli, which was first observed in the United States in 1988 (3). A. citrulli can cause severe infection on a wide range of cucurbits, including watermelon, cantaloupe, and pumpkin. Cotyledon symptoms are brown, angular, necrotic spots or large necrotic lesions. The disease is seedborne, so seeds usually serve as the primary inoculum source for BFB outbreaks (2). In July 2012, seedling blight was observed by local farmers from Anhui province in China on watermelon seedlings grafted to pumpkin rootstocks; lesions were morphologically similar to those caused by A. citrulli. Presence of A. citrulli was detected in symptomatic samples by using species-specific primers BX-L1/BX-S-R2 (1). The seed company claimed seeds of watermelon (cv. Changfeng) were certified free of bacterial fruit blotch, but pumpkin seeds (cv. Kangkuxianfeng-1) had not been tested for A. citrulli. For investigating the inoculum source, the remaining seeds of watermelon (cv. Changfeng) and pumpkin (cv. Kangkuxianfeng-1) for seedling production were collected from the farmer and processed for pathogen extraction as described by Walcott and Gitaitis (2). Two microliters of seed wash was used as template for PCR using primers BX-L1/BX-S-R2 (1). The experiment was conducted three times. A 279-bp DNA fragment was consistently amplified by PCR from seed wash of pumpkin seeds, but not from the seed wash of watermelon seeds. Three Acidovorax-like strains (A1, A2, and A3) were isolated from pumpkin seed wash using TWZ semi-selective medium (0.5% peptone, 0.025% CaCl2, 1% Tween-80, 50 mg/liter berberine, 50 mg/liter cycloheximide, 50 mg/liter 2,3,5-triphenyltetrazolium chloride). PCR was performed on the 16S rDNA gene from isolate strain A1, A2, and A3 (1,492 bp; GenBank Accession Nos. JX875533, JX875534, and JX875535) with primers rp1/fd2 (4), and PCR products were sequenced. Results of sequence analysis showed the sequences of strains A1, A2, and A3 were 99% identical to that of the type strain of A. citrulli AAC00-1 (NC_008752). Pathogencity was confirmed by injection of pumpkin cotyledons with bacterial suspensions of each isolate. Collected pumpkin seeds (n = 100 seeds) and watermelon seeds (n = 100 seeds) were planted in plastic pots containing sterilized field soil at room temperature to detect A. citrulli by a wet chamber growing out test. Eight days later, brown, angular, necrotic spots or wilt developed in pumpkin seedlings, but no symptoms were noted on the watermelon seedlings. To our knowledge, this is the first report of A. citrulli causing watermelon seedling blight transmitted from pumpkin seeds by grafting in China. References: (1) O. Bahar et al.

Abstract
The purpose of this study was to develop an efficient and, possibly, a practically operated methodology to recover phosphorus (P) from P-saturated dewatered aluminium sludge cakes (DASC) after the DASC have been beneficially reused as constructed wetlands substrate for P-rich wastewater treatment. A three-step procedure of 1) P extraction by H2SO4, 2) decolorization of extraction leachate via H2O2 oxidation, and 3) AlPO4 precipitation by pH adjustment, has been explored. The optimal conditions to form the precipitates of AlPO4 were determined, with 97% of P and 99% of Al being recovered. The obtained compounds were identified by XRD, FTIR and SEM analyses. Although the purity, structure, characteristics and production control of the compounds are worthy of further investigation, this study provides a showcase of a 'closed loop' regarding the beneficial reuse of a 'waste' and the recovery of useful elements after the reuse.
