Abstract
Objective: To investigate long-term health-related quality of life (HRQoL) and related factors in children with severe hemophilia A (HA) who received regular low-dose prophylaxis. Methods: Clinical data of severe HA children who began to receive regular low-dose coagulation factor Ⅷ (FⅧ) prophylaxis in Peking Union Medical College Hospital from January 1, 2008 to December 31, 2011 were retrospectively enrolled. The longest last follow-up period was May 31, 2023. The attendance of school or work and daily physical activity during the last follow-up were investigated. The patients were divided into full attendance group and incomplete attendence group according to attendance. The patients were divided into into exercise attainment group (reached Chinese sports recommendation) and exercise nonattainment group according to the exercise status. Barthel score was used to assess activities of daily living and Haemo-QoL was used to assess quality of life. Long-term HRQoL for children aged 8-16 years and patients aged 17 years and above were assessed using Haemo-QoL SF and Haem-A-QoL versions, respectively. Spearman correlation analysis was used to examine the correlation between treatment conditions and Haemo-QoL scores. Results: A total of 22 cases were enrolled, the prophylaxis initiation age ranged from 1.8-17.9 (10.4±3.8) years old. The average prophylactic FⅧ dose during low-dose prophylaxis was 24.2 U/kg per week and the follow-up time was 6.3-15.1 (9.6±2.8) years. At the last follow-up, the age of the patients was (20.2±5.4) years, of which 14 (63.6%) were adults over 18 years old. There were 15 patients in the full attendance group and 7 patients in the incomplete attendence group. Compared with the full attendance group, the incomplete attendence group had a smaller preventive treatment dose [M(Q1, Q3), (28.4±11.1) vs (15.3±3.7) U/kg, P=0.012], shorter preventive treatment time [148. 1 (18.6, 346.5) vs 48.0 (32.0, 156.9) weeks, P=0.017], and higher annual joint bleeding rate (AJBR) [12.5 (6.0, 22.3) vs 14.2 (13.2, 17.8) times, P=0.017]. There were 7 cases in the exercise attainment group and 15 cases in the exercise nonattainment group. Compared to the exercise attainment group, the exercise nonattainment group had shorter preventive treatment time[313. 7 (156.9, 366.0) vs 48.0 (16.5, 108.9) weeks, P=0.006], a higher AJBR [7.0 (5.1, 10.0) vs 23.3 (12.5, 29.8), P=0.003] and a higher hemophilia joint health score (HJHS) [9.0 (2.0, 15.5) vs 23.0 (12.0, 27.8), P=0.014]. Barthel score showed 81.8% (18 cases) of the patients' living ability was not influenced by the illness. In Haemo-QoL score, the total score of Haemo-QoL SF in 7 cases was (47.6±17.0) scores, the total score of Haem-A-QoL in 15 cases was (45.2±22.6) scores. The daily activity dimension of the Haem-A-QoL score was the lowest [38.2 (10.9, 45.5) scores], which was positively correlated with the starting age of prophylactic initiation (r=0.501, P=0.057), and negatively correlated with the duration of prophylaxis (r=-0.545, P=0.036). Conclusions: Regular low-dose prophylaxis could improve the long-term HRQoL of some children with severe HA, and children with higher prophylactic doses and longer prophylactic treatment time have higher quality of life.

Abstract
A retrospective analysis was conducted on a MonoMAC syndrome case admitted in October 2022 to the First Affiliated Hospital of Zhejiang University School of Medicine. The patient, a 16-year-old female with a history of persistent monocytopenia and mild anemia for several years, experienced recurrent symptoms of cough, expectoration, and fever, leading to multiple visits to the hospital. The diagnosis of MonoMAC syndrome was confirmed through comprehensive assessments including routine blood tests, pathogen metagenomic sequencing, lung and bone marrow biopsies, and next-generation sequencing of peripheral blood. The patient underwent haploidentical hematopoietic stem cell transplantation, with a smooth course of transplantation, achieving neutrophil engraftment on + 16 d and platelet engraftment on + 17 d, eventually restoring normal monocyte and NK cell counts. MonoMAC syndrome patients often initially present with infectious symptoms, and the diagnosis can be established based on significant monocytopenia in routine blood tests, history of non-tuberculous mycobacterial infections, and GATA2 germline mutations. Allogeneic hematopoietic stem cell transplantation may be required for some patients to improve their prognosis.

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
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
Oxaliplatin is an antineoplastic agent frequently used in the treatment of gastrointestinal tumors. However, it causes dose-limiting sensorimotor neuropathy, referred to as oxaliplatin-induced peripheral neuropathy (OIPN), for which there is no effective treatment. Here, we report that the elevation of neutrophil extracellular traps (NET) is a pathologic change common to both cancer patients treated with oxaliplatin and a murine model of OIPN. Mechanistically, we found that NETs trigger NLR family pyrin domain containing 3 (NLRP3) inflammasome activation and the subsequent release of IL18 by macrophages, resulting in mechanical hyperalgesia. In NLRP3-deficient mice, the mechanical hyperalgesia characteristic of OIPN in our model was reduced. In addition, in the murine model, treatment with the IL18 decoy receptor IL18BP prevented the development of OIPN. We further showed that eicosapentaenoic acid (EPA) reduced NET formation by suppressing the LPS-TLR4-JNK pathway and thereby abolished NLRP3 inflammasome activation and the subsequent secretion of IL18, which markedly prevented oxaliplatin-induced mechanical hyperalgesia in mice. These results identify a role for NET-triggered NLRP3 activation and IL18 release in the development of OIPN and suggest that utilizing IL18BP and EPA could be effective treatments for OIPN.

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 study the orthopedic treatment strategy for hemophilia complicated with musculoskeletal disorders as well as the peri-operative consumption of clotting factor. Methods: Total 338 orthopedic surgeries were performed for 261 patients, average age of 30.6 y (6-65 y) , with hemophilia between January 1996 and December 2019 at our institute. Two hundred and twenty-six patients presented with bleeds within the joints. Sixty-one patients presented with intramuscular bleeds, 45 presented with hemophilic pseudotumors, and six presented with miscellaneous complaints. Strategy of clotting factor replacement therapy was designed as per differences in the level of the operation procedure. Information regarding clinical manifestation, operative strategy, clotting factor consumption, and re-operation for complications was retrospectively recorded. The costs for multiple joint procedure and single joint procedure were studied. Results: We found that 270 of the 338 surgical procedures were major surgical procedures (79.9%) . There were 203 procedures of joint arthroplasty (60%) . Fourteen patients underwent reoperations for local recurrence (4.2%) . The average factor Ⅷ consumption before the surgery was 44.4 ± 8.1 IU/kg. The average FⅧ consumption within postoperative 2 weeks was 40 962 IU (647±177 IU/kg) . Seven type A hemophilic patients developed F Ⅷ inhibitor following the surgical procedure, with an average level of 13.7±11.2 BU/mL. Sixty-eight patients underwent multiple joint procedures under one anesthesia session (26%) . There was no significant difference in the factor consumption between the multiple joint procedure and single joint procedure. Conclusions: Surgical treatment was found to be effective for hemophilic arthropathy and lesion of the musculoskeletal apparatus, with the clotting factor replacement therapy. Multiple joint procedures under one anesthesia were more cost effective for patients with hemophilia, with less factor consumption than staged single joint procedure.

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
Most studies conducted nowadays to boost electrode performance in microbial fuel cell (MFC) have focused on carbonaceous materials. The titanium suboxides (Ti4O7, TS) are able to provide a new alternative for achieving better performance in MFC and have been tested and demonstrated in this study. The Ti4O7 electrode with high electrochemical activity was modified by graphene/polyaniline by the constant potential method. Electrogenic microorganisms were more conducive to adhere to the anode electrode due to the presence of graphene/polyaniline. The MFC reactor with polyaniline /graphene modified TS (TSGP) anode achieves the highest voltage with 980 mV, and produces a peak power density of 2073 mW/m2, which is 2.9 and 12.7 times of those with the carbon cloth anode, respectively, at the 1000 Ω external resistance. In addition, this study evaluates the effects of anolyte conductivity, pH, and COD on the treatment of oil-containing restaurant wastewater (OCRW) in MFC using TSGP anode. The OCRW amended with 120 mS/cm obtains the lowest internal resistance (160.3 Ω). Increasing the anodic pH, gradually from acidic (pH 5.5) to alkaline conditions (pH 8.0), resulted in a gradual increase in maximum power density to 576.4 mW/m2 and a decrease in internal cell resistance to 203.7 Ω. The MFC at the COD 1500 mg/L could obtain steady-state output voltage during 103 h while removing up to 65.2% of the COD of the OCRW.

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.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 673:230-236. [PMID: 30991314 DOI: 10.1016/j.scitotenv.2019.04.035] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/14/2019] [Revised: 04/02/2019] [Accepted: 04/03/2019] [Indexed: 06/09/2023]
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.
