Abstract
To investigate the role of co-stimulatory and co-inhibitory molecules on immune tolerance in immune thrombocytopenia (ITP), this study mapped the immune cell heterogeneity in the bone marrow of ITP at the single-cell level using Cytometry by Time of Flight (CyTOF). Thirty-six patients with ITP and nine healthy volunteers were enrolled in the study. As soluble immunomodulatory molecules, more sCD25 and sGalectin-9 were detected in ITP patients. On the cell surface, co-stimulatory molecules like ICOS and HVEM were observed to be upregulated in mainly central memory and effector T cells. In contrast, co-inhibitory molecules such as CTLA-4 were significantly reduced in Th1 and Th17 cell subsets. Taking a platelet count of 30×109 L-1 as the cutoff value, ITP patients with high and low platelet counts showed different T cell immune profiles. Antigen-presenting cells such as monocytes and B cells may regulate the activation of T cells through CTLA-4/CD86 and HVEM/BTLA interactions, respectively, and participate in the pathogenesis of ITP. In conclusion, the proteomic and soluble molecular profiles brought insight into the interaction and modulation of immune cells in the bone marrow of ITP. They may offer novel targets to develop personalized immunotherapies.

Abstract
Urolithiasis, or the formation of calculi in the urinary system, represents a prevalent urological condition frequently encountered among individuals aged 30 to 55 years. An in-depth analysis of the composition of these calculi holds significant promise in shedding light on the underlying etiological and pathogenic factors contributing to this ailment. The primary objective of this study was to delineate the principal components comprising urinary system calculi within a cohort of patients who sought medical intervention at a tertiary grade A hospital located in Baoding City. Furthermore, our investigation entailed a comprehensive examination of the physical and morphological characteristics exhibited by these calculi. In this study, a total of 2307 individuals afflicted with urinary system calculi were recruited as participants, and a corresponding number of 2307 calculous specimens were subjected to thorough examination. The specimens were examined using infrared spectroscopy. We collected and examined patient data including gender, age, location of the calculi, employment status, residential area, and other factors. The middle-aged demographic exhibited a conspicuous predilection for urinary system calculi, wherein a notable gender disparity was observed, with a male-to-female ratio of 1.63 to 1. Among the enrolled patients, kidney calculi were prevalent in 1270 cases, ureteral calculi were documented in 983 cases, and bladder calculi were encountered in 46 instances. Notably, the principal components comprising these calculi were identified as calcium oxalate and apatite, while uric acid and ammonium magnesium phosphate were comparatively less frequently encountered. Furthermore, the analysis of calculus composition across patients residing in distinct geographical regions did not reveal any statistically significant variations. The identification of components within upper urinary tract calculi plays a pivotal role in elucidating the root causes of calculus formation. This valuable information empowers healthcare professionals, particularly nursing staff, to provide personalized dietary and health guidance to patients, thereby enhancing the quality of care and promoting more effective management of this condition.

Abstract
Inflammatory bowel disease (IBD) is comprised of ulcerative colitis and Crohn's disease, the pathogenesis of which is closely related to intestinal flora disorders. Abnormalities in the intestinal microenvironment caused by intestinal flora disorders affect amino acid metabolism. Tryptophan is an essential amino acid, and its metabolites are involved in the regulation of immunity, neuronal function, intestinal homeostasis, etc. The development of IBD disease is accompanied by tryptophan deficiency or metabolic abnormalities. This review focuses on the relationship between the intestinal flora metabolite tryptophan and its metabolites and the occurrence and development of IBD disease, and provides new ideas for future diagnostic methods for predicting IBD disease activity and protocols for treating IBD.

Abstract
INTRODUCTION Prostate-specific antigen-based screening for prostate cancer reportedly does not improve cancer-specific survival. However, there remain concerns about the increasing incidence of advanced disease at initial presentation. Here, we investigated the incidences and types of complications that occur during the course of disease in patients with metastatic hormone-sensitive prostate cancer (mHSPC). METHODS This study included 100 consecutive patients who were diagnosed with mHSPC at five hospitals from January 2016 to August 2017. Analyses were conducted using patient data extracted from a prospectively collected database, along with information about complications and readmission obtained from electronic medical records. RESULTS The median patient age was 74 years and the median serum prostate-specific antigen level at diagnosis was 202.5 ng/mL. Ninety-nine patients received androgen deprivation therapy; 17 of these patients also received chemotherapy. During a mean follow-up period of 32.9 months, 41 patients reported bone pain; of these patients, 21 developed pathologic fractures and eight had cord compression. Twenty-eight patients developed retention of urine; of these patients, 10 (36%) required surgery and 11 (39%) required long-term urethral catheter use. Among 15 patients who developed ureteral obstruction, four (27%) required ureteral stenting and four (27%) required long-term nephrostomy drainage. Other complications included anaemia (41%) and deep vein thrombosis (4%). Fifty-nine (59%) patients had ≥1 unplanned hospital admission during the course of disease; 16% of such patients had >5 episodes of readmission. CONCLUSION Among patients with mHSPC, 70% experienced disease-related complications and unplanned hospital admissions, which substantially burdened both patients and the healthcare system.

Abstract
OBJECTIVE To explore the clinical characteristics and prognosis of multiple myeloma(MM) patients with secondary primary malignancies. METHODS The clinical data of newly diagnosed MM patients admitted to the First Affiliated Hospital of Zhengzhou University from January 2011 to December 2019 were retrospectively analyzed. The patients with secondary primary malignancies were retrieved, and their clinical features and prognosis were evaluated. RESULTS A total of 1 935 patients with newly diagnosed MM were admitted in this period, with a median age of 62 (18-94) years old, of which 1 049 cases were hospitalized twice or more. There were eleven cases with secondary primary malignancies (the incidence rate was 1.05%), including three cases of hematological malignancies (2 cases of acute myelomonocytic leukemia and 1 case of acute promyelocytic leukemia) and eight cases of solid tumors (2 cases of lung adenocarcinoma, and 1 case each of endometrial cancer, esophageal squamous cell carcinoma, primary liver cancer, bladder cancer, cervical squamous cell carcinoma, and meningioma). The median age of onset was 57 years old. The median time between diagnosis of secondary primary malignancies and diagnosis of MM was 39.4 months. There were seven cases with primary or secondary plasma cell leukemia, the incidence rate was 0.67%, and the median age of onset was 52 years old. Compared with the randomized control group, the β2-microglobulin level in the secondary primary malignancies group was lower (P=0.028), and more patients were in stage I/II of ISS (P=0.029). Among the 11 patients with secondary primary malignancies, one survived, ten died, and the median survival time was 40 months. The median survival time of MM patients after the secondary primary malignancies was only seven months. All seven patients with primary or secondary plasma cell leukemia died, with a median survival time of 14 months. The median overall survival time of MM patients with secondary primary malignancies was longer than that of the patients with plasma cell leukemia (P=0.027). CONCLUSION The incidence rate of MM with secondary primary malignancies is 1.05%. MM patients with secondary primary malignancies have poor prognosis and short median survival time, but the median survival time is longer than that of patients with plasma cell leukemia.

Abstract
Objective: To estimate the consumption level of four drugs in Beijing using wastewater-based epidemiology (WBE). Methods: The primary sludge from one large wastewater treatment plants (WWTPs) was collected in Beijing from July 2020 to February 2021. The concentrations of codeine, methadone, ketamine and morphine in the sludge were detected through solid-phase extraction-liquid chromatography-tandem mass spectrometry. The consumption, prevalence and number of users of four drugs were estimated by using the WBE approach. Results: Among 416 sludge samples, codeine had the highest detection rate (82.93%, n=345) with a concentration [M(Q1, Q3)] of 0.40 (0.22-0.8) ng·g-1, and morphine had the lowest detection rate (28.37%,n=118) with a concentration [M(Q1, Q3)] of 0.13 (0.09, 0.17) ng·g-1. There was no significant difference in the consumption of the four drugs on working days and weekends (all P values>0.05). Drug consumption was significantly higher in winter than that in summer and autumn (all P values<0.05). The consumption [M(Q1, Q3)] of codeine, methadone, ketamine and morphine in winter was 24.9 (15.58, 38.6), 9.39 (4.57, 26.72), 9.84 (5.18, 19.45) and 5.67 (3.57, 13.77) μg·inhabitant-1·day-1, respectively. For these drugs, there was an upward trend in the average drug consumption during summer, autumn and winter (the Z values of the trend test were 3.23, 3.16, 2.19, and 3.32, respectively and all Pvalues<0.05). The prevalence [M(Q1, Q3)] of codeine, methadone, ketamine and morphine were 0.0056% (0.0034%, 0.0092%), 0.0148% (0.009%, 0.0267%)、0.0333% (0.0210%, 0.0710%) and 0.0072% (0.0038%, 0.0117%), respectively. The estimated number of drug users [M(Q1, Q3)] was 918 (549, 1 511), 2 429 (1 578, 4 383), 5 451 (3 444, 11 642) and 1 173 (626, 1 925). Conclusion: Codeine, methadone, ketamine and morphine have been detected in the sludge of WWTPs in Beijing, and the consumption level of these drugs varies in different seasons.

Abstract
Parastomal hernia is a common complication after abdominal ostomy. Although the European Hernia Society guidelines recommend surgical treatment for parastomal hernia, there is still no "gold standard" procedure. The exploration and practice of parastomal hernia repair surgery has been carried out for many years, from the earlier hernia ring suture and stoma relocation repair, to the reinforcement of meshes (such as the Keyhole repair technique and the Sugarbaker repair technique) and the application of laparoscopic technique, and then to the combination of various methods. The intervention of single-port laparoscopic technique and robot-assisted surgery, the prevention of parastomal hernia, the specialization of treatment, multidisciplinary cooperation, and the improvement of diagnostic methods will all provide more optimal solutions for stoma patients. This article will review and summarize the development process and evaluation of parastomal hernia surgical techniques.

Abstract
Objective: To investigate the detection of occupational health for vinyl chloride workers in Tianjin. Methods: In this study, we have collected data from 7 companies with vinyl chloride hazards in 16 districts of Tianjin. Finally, the occupational health surveillance data of 478 vinyl chloride-exposed workers were included in the analysis. Quantitative data was tested for normality. If the data conforms to the normal distribution, using the Mean±SD for statistical description, and t test for statistical analysis. If the data does not conform to the normal distribution, using Median (Q(1), Q(100)) for statistical description, rank sum test for statistical analysis. The qualitative data was described by composition ratio, and the chi-square test was used for statistical analysis. The logistic regression was used to assess the impact on suspected occupational disease and occupational contraindication from personal general conditions, occupational history, company information. Results: The abnormal detection rate of vinyl chloride monomer workers in Binhai New Area was higher than that in other areas (χ(2)=5.20, P=0.023). The abnormal detection rate of vinyl chloride monomer workers in non manufacturing industries was higher than that in manufacturing industries (χ(2)=7.74, P=0.005). The abnormal detection rate of vinyl chloride monomer workers in domestic enterprises was higher than that in foreign invested enterprises (χ(2)=22.38, P<0.01). Compared with the normal group of vinyl chloride monomer workers, the abnormal group of workers was older and had longer working years, The difference was statistically significant (Z=-3.32, -3.54, P=0.001, <0.01). The employer of vinyl chloride monomer workers is in Binhai New Area, the economic type is domestic funded enterprise, the industry is classified as non manufacturing industry, the age is more than 40 years old, and the length of service is more than 20 years old, which is the influencing factor for workers to detect abnormalities (OR=1.875, 95%CI: 1.279~2.749; OR=1.657, 95%CI: 1.071~2.563; OR=3.562, 95%CI: 2.057~6.170; OR=2.166, 95%CI: 1.245~3.768; OR=1.968, 95%CI: 1.345~2.879, all P<0.05) . Conclusion: To protect the health of workers and prevent occupational diseases, the management of vinyl chloride exposure on production process, especially in domestic enterprise, should be improved. Also, better occupational health surveillance should be provided to female workers.

Abstract
Objective: To analyze the level and trend of occupational pneumoconiosis disease burden in Tianjin from 2010 to 2019, and to provide scientific basis for making prevention and control countermeasures and suggestions. Methods: In June 2021, the data of occupational pneumoconiosis cases in Tianjin from 2010 to 2019 were selected from Follow-up survey of occupational pneumoconiosis patients in Tianjin and occupational "Health Hazardous Surveillance Information System", the subsystem of China Disease Control and Prevention Information System. Disability-adjusted life year (DALY) , years of life lost (YLL) and years lost due to disability (YLD) were used to comprehensively measure the disease burden of occupational pneumoconiosis by region, year, disease type, industry, sex and age; Kruskal-wallis H test was used for univariate analysis of DALY loss in pneumdo-niosis occupational. Results: A total of 43089 person-years of DALY due to pneumoconiosis in Tianjin from 2010 to 2019, of which the YLD accounted for about 2/3 (28277 person-years) , the YLL accounted for about 1/3 (14812 person-years) , and the average DALY was 7.34 person-years. The industrial distribution of pneumoconiosis burden in Tianjin was mainly concentrated in the manufacturing industry accounting for 90.6% of the whole industry. The disease types were mainly concentrated in silicosis, foundry pneumoconiosis, asbestosis and cement pneumoconiosis accounting for 34.4%, 16.9%, 13.3% and 10.5%, and the age distribution was mainly concentrated in the 50~<85 years old age group, accouling for 83.6%. The median DALY of occupational pneumoconiosis patients with different pneumoconiosis stages, disability grades and years of service exposed to dust were statistically significant (P<0.05) . Conclusion: The disease burden of occupational pneumoconiosis in Tianjin was still serious. It is necessary to take targeted intervention measures for key industries and population.

Abstract
This study is to investigate the effect of valve ablation on bladder function in patients with posterior urethral valves. The clinical data of patients with posterior urethral valves who received urodynamic examination before and after valve ablation were retrospectively analyzed.The bladder compliance improved during urine storage after operation, and the maximum detrusor pressure decreased during micturition. The postoperative urinary system ultrasound showed that the residual urine volume of the group with significantly improved upper urinary tract hydrocephalus was significantly less than that of the group with no improvement. The bladder compliance was significantly higher than that of the group with no improvement, and the maximum urine flow rate was significantly higher than that of the group with no improvement (all P<0.05). Valve ablation has limited effect on improving bladder function in patients with PUV. Valve incision can help improve the maximum bladder volume, residual urine volume and maximum urinary flow rate. It has a certain effect on bladder compliance and maximum detrusor pressure.

Abstract
Objective: To evaluate the effect of topical glucocorticoid in treating phimosis on urinarytract infection(UTI) of vesicoureteral reflux(VUR) in infants. Methods: Clinical data of infants with UTI diagnosed as primary VUR admitted to our hospital from January 2016 to January 2021 were retrospectively analyzed. The children were divided into three groups:the effective group (topical glucocorticoid was effective in the treatment of phimosis), the ineffective group(topical glucocorticoid was ineffective in the treatment of phimosis), and the untreated group(phimosis was not treated). Age of onset, degree of reflux, side and other indicators were compared to understand the effectiveness of topical glucocorticoid in treating phimosis, and the clinical characteristics of repeated UTI with VUR in treated phimosis and untreated phimosis. Results: A total of 544 children were included. Among them, 59 cases were treated with topical glucocorticoid for phimosis, 48 cases in the effective group, and their age was (12.5±8.4) months;11 cases in the ineffective group,and their age was (11.2±8.9) months. There were 485 cases in the untreated group, and their age was (13.1±9.3) months.The effective rate of topical glucocorticoid in the treatment of phimosis was 81.36%. There were 12 cases(12/48) of recurrent UTI in the effective group and 213 cases (213/485)of recurrent UTI in the untreated group, and the difference between the two groups was statistically significant (P=0.008). Conclusion: Treatment of phimosis with topical glucocorticoid is an effective, easy to perform, and cost-effective method, and can effectively reduce the risk of recurrent UTI in infants with primary VUR.

Abstract
Bacterial adaptation is largely shaped by horizontal gene transfer, xenogeneic silencing mediated by lineage-specific DNA bridgers (H-NS, Lsr2, MvaT and Rok), and various anti-silencing mechanisms. No xenogeneic silencing DNA bridger is known for α-proteobacteria, from which mitochondria evolved. By investigating α-proteobacterium Sinorhizobium fredii, a facultative legume microsymbiont, here we report the conserved zinc-finger bearing MucR as a novel xenogeneic silencing DNA bridger. Self-association mediated by its N-terminal domain (NTD) is required for DNA–MucR–DNA bridging complex formation, maximizing MucR stability, transcriptional silencing, and efficient symbiosis in legume nodules. Essential roles of NTD, CTD (C-terminal DNA-binding domain), or full-length MucR in symbiosis can be replaced by non-homologous NTD, CTD, or full-length protein of H-NS from γ-proteobacterium Escherichia coli, while NTD rather than CTD of Lsr2 from Gram-positive Mycobacterium tuberculosis can replace the corresponding domain of MucR in symbiosis. Chromatin immunoprecipitation sequencing reveals similar recruitment profiles of H-NS, MucR and various functional chimeric xenogeneic silencers across the multipartite genome of S. fredii, i.e. preferring AT-rich genomic islands and symbiosis plasmid with key symbiosis genes as shared targets. Collectively, the convergently evolved DNA bridger MucR predisposed α-proteobacteria to integrate AT-rich foreign DNA including symbiosis genes, horizontal transfer of which is strongly selected in nature.

Abstract
Patients with inflammatory bowel disease (IBD) have a significantly higher incidence of psychological issues than the general population. Anxiety and depression are the most common psychological problems. These psychological problems have an adverse impact on the quality of life and prognosis of IBD patients. Low quality of life and complex course of disease also aggravate patients' anxiety and depression. The disorder of the brain-gut axis is the important mechanism in bi-directional interactions between IBD disease activity and psychological issues. More and more attention has been paid to the diagnostic approaches for psychological conditions and standardized management in IBD. This article reviews the common psychological issues in IBD patients, the interactions between psychological issues and IBD disease activity, and related management of psychological problems in patients with IBD.

Abstract
Objective: To investigate the detection of suspected occupational diseases and occupational contraindications for benzene workers in Tianjin. Methods: In June 2020, the occupational health inspection data of 16113 benzene workers in 514 enterprises with benzene hazards in 16 municipal districts in Tianjin from January to December 2019 were included in the analysis. Enterprise information included the employer's region, economic type, industry classification and enterprise scale. Occupational health inspection data for benzene workers during their on-the-job period included routine inspection indicators and benzene special inspection indicators. Multivariate unconditional logistic regression was used to analyze the relationship between personal general information, occupational history, enterprise information and suspected benzene poisoning and occupational contraindications of benzene workers. Results: There were 16073 benzene workers in the normal group and 24 in the suspected benzene poisoning group. The detection rate of suspected benzene poisoning in females was higher than that in males (χ(2)=8.26, P=0.004) . There was no significant difference in the detection rates of suspected benzene poisoning among different dimensions such as age, length of service, occupational health inspection institution location, employer location, industry classification, economic type, and enterprise scale (P>0.05) . There were 16073 benzene workers in the normal group and 16 in the benzene contraindication group. The detection rate of benzene contraindications for workers in suburban areas where occupational health inspection institutions were located was higher than that in urban areas (χ(2)=9.71, P=0.002) , and there was no significant difference in the detection rates of contraindications for benzene in other dimensions (P>0.05) . Multivariate logistic regression analysis showed that female benzene workers were more likely to detect suspected benzene poisoning (OR=3.53, 95%CI: 1.57-7.94, P=0.002) ; benzene workers who received physical examination in suburban occupational health inspection institutions (OR=5.81, 95%CI: 1.94-17.42, P=0.002) , the employer's area was in the suburbs (OR=9.68, 95%CI: 1.23-76.07, P=0.031) , and female workers (OR=3.07, 95%CI: 1.13-8.37, P=0.028) , it was easier to detect occupational contraindications. Conclusion: Female benzene workers with employers located in the suburbs have a higher risk of detecting occupational contraindications, and women are more likely to detect suspected benzene poisoning. The management of benzene operations in the production environment of enterprises in the suburbs of Tianjin and the occupational health monitoring of female workers should be strengthened.

Abstract
INTRODUCTION Synaptic N-methyl-d-aspartate receptor subtype 2B(NR2B) is significantly reduced in prefrontal cortex (PFC) in the neurodevelopmental methylazoxymethanol (MAM) model of schizophrenia (SCZ). Recent research has shown that LY395756 can effectively restore NR2B levels and improve cognitive performance in juvenile MAM mice model. However, the underlying mechanisms of these beneficial effects remain unclear. MATERIALS AND METHODS Juvenile MAM mice model of SCZ is used in our study. Synaptic membrane protein levels were examined by western blotting under different treatment conditions. Interaction of cAMP-response element binding protein (CREB) and the promoter of NR2B was detected by the chromatin immunoprecipitation (ChIP) assay. Further examination of signaling pathway that mediates NR2B expression was also investigated by western blotting. RESULTS In the PFC of the juvenile MAM mice schizophrenia model, CREB was found to directly bind with the promoter of NR2B. LY395756 activated the phosphorylation of AKT. Phosphorylated AKT subsequently induced the phosphorylation of CREB, and the activated CREB promoted the expression of NR2B. Subsequent experiments showed that the dephosphorylation of CREB induced by protein phosphatase 1 (PP1) can inhibit NR2B levels. Taken together, these findings support that the AKT/CREB signaling pathway is essential for the promoting effect of LY395756 on synaptic NR2B in PFC in juvenile MAM mice SCZ model. CONCLUSIONS Our investigation has identified a novel mechanism by which LY395756 increases NR2B expression in juvenile MAM mice SCZ model. The AKT/CREB signaling pathway warrants further research as a potential direction for clinical treatment of SCZ.

Abstract
OBJECTIVE To compare the effect of Tongyuan acupuncture combined with medication and medication alone on pregnancy outcome in patients with recurrent implantation failure (RIF) of thin endometrium type. METHODS A total of 74 patients with RIF of thin endometrium type undergoing freeze-thaw embryo transfer were randomly divided into an observation group (37 cases) and a control group (37 cases). The patients in the control group were treated with freeze-thaw embryo transfer in hormone replacement cycle, and the estradiol valerate tablets were taken orally from the fifth day of menstruation, 2 mg per day. On the basis of the control group, the observation group was additionally treated with Tongyuan acupuncture at Baihui (GV 20), Dazhui (GV 14), Qihai (CV 6), Guanyuan (CV 4), etc., combined with other acupoints based on syndrome differentiation and menstrual stage, once every other day. Both groups were treated for 3 menstrual cycles. The clinical pregnancy rate and embryo implantation rate of the two groups were observed after transplantation; the endometrial thickness and type, resistance index (RI) and pulsatility index (PI) of endometrial blood flow were measured before treatment and one day before transplantation, and adverse reactions was recorded. RESULTS The clinical pregnancy rate was 37.8% (14/37) in the observation group, which was higher than 16.2% (6/37) in the control group (P<0.05). There was no significant difference in embryo implantation rate between the two groups (P>0.05). One day before transplantation, the endometrial thickness and the proportion of type A in endometrial classification in the two groups were increased compared with those before treatment (P<0.01), and those in the observation group were higher than the control group (P<0.01, P<0.05). The PI and RI of endometrial blood flow in the two groups were lower than those before treatment (P<0.01), and those in the observation group were lower than the control group (P<0.01, P<0.05). During the treatment, 6 patients in the control group had discomfort such as breast distending pain, stomach pain, dizziness and nausea, and there were no adverse reaction in the observation group. CONCLUSION On the basis of conventional medication, Tongyuan acupuncture could increase the endometrial thickness, improve endometrial receptivity, improve pregnancy outcome and reduce adverse reactions in patients with RIF of thin endometrial type.

Abstract
Objective: To explore the main influencing factors of leucopenia in benzene workers. Methods: The data of 514 benzene hazardous enterprises and 97 non benzene hazardous enterprises in 16 municipal districts of Tianjin from January to December 2019 were collected. A total of 16113 benzene exposed workers and 5817 non benzene exposed workers were included in the study. The occupational health examination data of workers during on-the-job were analyzed, and they were divided into white blood cell count reduction group and white blood cell count normal group. Additive interaction was used to evaluate the effects of workers' general situation, occupational history, enterprise information and benzene exposure on leukocyte count reduction. Results: The age and length of service of workers in the white blood cell count reduction group were higher than those in the white blood cell count normal group (Z=-3.411, -4.539, P<0.01) . The detection rate of white blood cell count reduction in women was higher than that in men (χ(2)=211.631, P<0.01) . The detection rate of white blood cell count reduction in workers in enterprises located in urban areas, classified as manufacturing and small and micro enterprises was higher than that in workers in suburbs, non manufacturing and large and medium-sized enterprises (χ(2)=8.039, 4.232, 37.478, P<0.05) . The additive interaction analysis of the influencing factors of white blood cell count reduction showed that there was additive interaction between gender and benzene exposure, the relative excess risk ratio (RERI) , attribution ratio (AP) and interaction index (S) were 3.789 (95%CI: 2.280-5.299) , 0.571 (95%CI: 0.414-0.726) and 3.045 (95%CI: 1.699-5.459) , respectively. Conclusion: The management of benzene operation in the production environment of small and micro manufacturing enterprises in Tianjin should be strengthened, as well as the personal protective articles and occupational health protection measures for female operators, so as to protect the health of operators and prevent the occurrence of occupational diseases.

Abstract
The ubiquitous bacterial second messenger c-di-GMP is intensively studied in pathogens but less so in mutualistic bacteria. Here, we report a genome-wide investigation of functional diguanylate cyclases (DGCs) synthesizing c-di-GMP from two molecules of GTP in Sinorhizobium fredii CCBAU45436, a facultative microsymbiont fixing nitrogen in nodules of diverse legumes, including soybean. Among 25 proteins harboring a putative GGDEF domain catalyzing the biosynthesis of c-di-GMP, eight functional DGCs were identified by heterogenous expression in Escherichia coli in a Congo red binding assay. This screening result was further verified by in vitro enzymatic assay with purified full proteins or the GGDEF domains from representative functional and nonfunctional DGCs. In the same in vitro assay, a functional EAL domain catalyzing the degradation of c-di-GMP into pGpG was identified in a protein that has an inactive GGDEF domain but with an active phosphodiesterase (PDE) function. The identified functional DGCs generally exhibited low transcription levels in soybean nodules compared to free-living cultures, as revealed in transcriptomes. An engineered upregulation of a functional DGC in nodules led to a significant increase of c-di-GMP level and symbiotic defects, which were not observed when a functional EAL domain was upregulated at the same level. Further transcriptional analysis and gel shift assay demonstrated that these functional DGCs were all transcriptionally repressed in nodules by a global pleiotropic regulator, MucR1, that is essential in Sinorhizobium-soybean symbiosis. These findings shed novel insights onto the systematic regulation of c-di-GMP biosynthesis in mutualistic symbiosis. IMPORTANCE The ubiquitous second messenger c-di-GMP is well-known for its role in biofilm formation and host adaptation of pathogens, whereas it is less investigated in mutualistic symbioses. Here, we reveal a cocktail of eight functional diguanylate cyclases (DGCs) catalyzing the biosynthesis of c-di-GMP in a broad-host-range Sinorhizobium that can establish nitrogen-fixing nodules on soybean and many other legumes. These functional DGCs are generally transcribed at low levels in soybean nodules compared to free-living conditions. The engineered nodule-specific upregulation of DGC can elevate the c-di-GMP level and cause symbiotic defects, while the upregulation of a phosphodiesterase that quenches c-di-GMP has no detectable symbiotic defects. Moreover, eight functional DGCs located on two different replicons are all directly repressed in nodules by a global silencer, MucR1, that is essential for Sinorhizobium-soybean symbiosis. These findings represent a novel mechanism of a strategic regulation of the c-di-GMP biosynthesis arsenal in prokaryote-eukaryote interactions.

Abstract
Disease modelling has had considerable policy impact during the ongoing COVID-19 pandemic, and it is increasingly acknowledged that combining multiple models can improve the reliability of outputs. Here we report insights from ten weeks of collaborative short-term forecasting of COVID-19 in Germany and Poland (12 October-19 December 2020). The study period covers the onset of the second wave in both countries, with tightening non-pharmaceutical interventions (NPIs) and subsequently a decay (Poland) or plateau and renewed increase (Germany) in reported cases. Thirteen independent teams provided probabilistic real-time forecasts of COVID-19 cases and deaths. These were reported for lead times of one to four weeks, with evaluation focused on one- and two-week horizons, which are less affected by changing NPIs. Heterogeneity between forecasts was considerable both in terms of point predictions and forecast spread. Ensemble forecasts showed good relative performance, in particular in terms of coverage, but did not clearly dominate single-model predictions. The study was preregistered and will be followed up in future phases of the pandemic.

Abstract
Portable ultrasound has been extensively used for diagnostic applications in health monitoring, emergency rooms, and ambulances. However, these handheld ultrasound systems may suffer from heat and battery issues attributed to the large power consumption of the transmitter. Additionally, the largest portion of the direct current (DC) power consumption can be attributed to the amplifier in the digital-to-analog converter (DAC) of the transmitter and to the analog-to-digital converter (ADC) of the receiver. Therefore, the number of transmit/receive channels in a portable ultrasound instrument is one of the crucial design factors regarding heat and battery related issues. To address these problems, we propose an acoustic-field beamforming (AFB) technique for low-power portable ultrasound systems with a single receive and five transmit channels. Finally, the simulation, experimental, and in vivo results verified the feasibility of this approach.

Abstract
The root of Angelica sinensis is one of the most widely used traditional Chinese medicines. In commercial planting, early bolting and flowering (EBF) of ca. 40% of 2-year-old plants reduces root yield and quality. Although changes in physiology in bolted plants have been investigated, the mechanism activating EBF has not been identified. Here, transcriptomics profiles at four different growth stages (S1 to S4) were performed, gene expression was validated by qRT-PCR and the accumulation of endogenous hormones quantified by HPLC. A total of 60,282 unigenes were generated, with 2,282, 1,359 and 2,246 differentially expressed genes (DEGs) observed at S2 versus S1, S3 versus S2 and S4 versus S3, respectively; 558 genes that co-exist in at least three stages from S1 to S4 were obtained. Functional annotation classified 38 DEGs linked to flowering pathways: photoperiodism, hormone signalling, carbohydrate metabolism and floral development. The levels of gene expression, hormones (GA1 , GA4 and IAA) and soluble sugars were consistent with the EBF. It can be concluded that the EBF of A. sinensis is controlled by multiple genes. This integrated analysis of transcriptomics, together with targeted hormones and soluble sugars, provides new insights into the regulation of EBF of A. sinensis.

Abstract
One 51 years old man was admitted to the rheumatology department with a history of prominent eyes, headache and blurred vision for half year. The main manifestations included retrobulbar inflammatory pseudotumor and retroperitoneal fibrosis. He was initially diagnosed as granulomatosis with polyangiitis. Prednisone and cyclophosphamide were administrated and effective. New mass of dura mater and osteosclerosis presented during follow up. Finally Erdheim Chester disease(ECD) was diagnosed by biopsy and pathological examination. Vemurafenib, a v-raf murine sarcoma viral oncogenes homolog B1 (BRAF) inhibitor, 480 mg was given twice a day. The patient's condition is stable and still in follow-up. Although ECD is a rare histiocytosis, clinicians should pay attention to its manifestations and differential diagnoses.

Abstract
For over two decades photoacoustic imaging has been tested clinically, but successful human trials have been limited. To enable quantitative clinical spectroscopy, the fundamental issues of wavelength-dependent fluence variations and inter-wavelength motion must be overcome. Here we propose a real-time, spectroscopic photoacoustic/ultrasound (PAUS) imaging approach using a compact, 1-kHz rate wavelength-tunable laser. Instead of illuminating tissue over a large area, the fiber-optic delivery system surrounding an US array sequentially scans a narrow laser beam, with partial PA image reconstruction for each laser pulse. The final image is then formed by coherently summing partial images. This scheme enables (i) automatic compensation for wavelength-dependent fluence variations in spectroscopic PA imaging and (ii) motion correction of spectroscopic PA frames using US speckle tracking in real-time systems. The 50-Hz video rate PAUS system is demonstrated in vivo using a murine model of labelled drug delivery.

Abstract
Objective: To explore the association between blood pressure (BP) and the left ventricular mass (LVM) in children aged 6-8 years. Methods: The participants were from the community-based census-like design child cohort on sensitization, puberty, obesity and cardiovascular risk (PROC) conducted in six public non-boarding primary schools in Shunyi District, Beijing. Repeated three measurements on anthropometrical, M-mode and 2-dimensional (2D) echocardiographic imaging (2D/M ECHO) and blood biochemical assay, and BP measurements were carried out at baseline and follow-up from October 2018 to June 2019. A total of 1 659 children who had repeated BP measurements and cardiac structure information were included in this study. The average value of last two measurements of BP was determined as BP value for analysis. Formula recommended by Devereux was used to calculate the mass of left ventricle. Robust linear regression models were used to explore the association between BP and LVM in different groups. Results: The average age of all patients was (7.10±0.29) years old, including 832 boys (50.15%). Of all, 83.54% (1 386/1 659) were grouped as normal BP with average LVM (58.54±13.33) g, and 16.46% (273/1 659) as elevated BP group with LVM (63.84±15.78) g (P<0.001). The LVM of the normal BP group was lower than elevated BP group in overall participants, boys and girls (P<0.005). Univariate analysis showed that systolic BP was associated with LVM in overall, boys and girls (P<0.001) respectively. While diastolic BP was associated with LVM in overall and girls (P<0.03). Multivariable analysis indicated that the associations between systolic BP and LVM were observed in overall, boys and girls (P<0.05) with the β (95%CI)=0.14 (0.08, 0.21), 0.18 (0.08, 0.27) and 0.12 (0.03, 0.22), respectively. However, the associations of diastolic BP and LVM were not significant. Conclusion: Systolic BP is highly associated with LVM and elevated BP could increase the LVM in children. Boys with elevated BP present a larger LVM and might indicate higher risk of left ventricular hypertrophy in adulthood.

Abstract
Objective: The study is to explore the association between trunk fat index (TFI) and carotid intima-media thickness (cIMT) among children aged 6-8 years old in Shunyi District, Beijing. Methods: The participants were enrolled from the child cohort on sensitization, puberty, obesity and cardiovascular risk (PROC) conducted in Shunyi District, Beijing from October 2018 to June 2019. The PROC used a community-based census-like design, and all eligible first-grade children from six public non-boarding primary schools in urban area were approached. Finally, a total of 1 503 children with written informed consent from parents and had complete data of TFI and cIMT were included for the present study. Sequential baseline surveys including anthropometric measurements, laboratory testing and ultrasonography measurement were conducted to collect the data on height, weight, body composition, blood pressure, serum lipids and cIMT. Linear regression was used to determine the predictors of cIMT, receiver operating characteristic (ROC) curve analysis was used to determine the cut-off value of TFI to identify children with high cIMT, and analysis of covariance was used to evaluate the post-consistency classification of cIMT by TFI. Results: The age of 1 503 participants was (6.7±0.3) years, and 752 boys accounted for 50.0%. The average cIMT was (0.358±0.024) and (0.355±0.023) mm, and the M (P25, P75) of TFI was 0.70 (0.22, 1.78) and 0.74 (0.23, 1.52) kg/m2 for boys and girls, respectively. The detection rates for boys and girls of high cIMT were 2.1% and 3.3%, respectively. Linear regression analysis showed that height, systolic blood pressure (SBP), diastolic blood pressure (DBP), TFI were positively correlated with cIMT in boys (P values<0.05). And height, SBP, triglyceride (TG), TFI were positively correlated with cIMT, and high-density lipoprotein cholesterol (HDL-C) was negatively correlated with cIMT in girls (P values<0.05). ROC curve analysis indicated that the best cut-off values for TFI to identify children with high cIMT were 1.78 and 1.14 kg/m2, at P75 and P66 for boys and girls, respectively. After grouped with the cut-off value of TFI and adjusted for age, height, SBP, DBP, TG, HDL-C, multivariable covariance analysis showed a consistent cut-off of inter-group cIMT mean by TFI groups (P values<0.005). Conclusion: TFI is associated with cIMT, which underscore its application potential in identifying early vascular structural damage.

Abstract
Objective: To explore sex difference in height growth and blood pressure (BP) change among Beijing school-age children and adolescents. Methods: Using physical examination data of 70 769 school-age children and adolescents from primary to high school during 2009-2018 in Shunyi District, a longitudinal dataset was formed with completed anthropometrical measurements of height and blood pressure (BP) after individual information linkage. Age-specific height, BP, growth rate of height and BP as well BP growth rate based on age at peak height velocity (PHA) were calculated. Linear mixed-effects model was used to identify sex disparity in the growth rates of height and BP. Results: Height and BP increased with age in both boys and girls, and the mean height and BP of boys were always higher than those of girls, except age group from 10 to 11 years. Sex disparity existed in growth rates of height and BP (P<0.001), which was demonstrated by the interaction item of"sex x age"in linear mixed-effects model. The PHA of boys was 12 years old, which was 2 years later than that of girls, about 10 years old. The curves of BP growth rate with age showed double peaks in both boys and girls. Boys reached the peak BP velocity at 13 years old, 3 years lagging behind that of girls who reached the peak at 10 years old. However, the peak of height and BP velocity of boys were higher than that of girls. The change of BP was highly synchronized in time with the increase of height, after adjusting for the growth rate of height by PHA. BP velocity increased with age before onset of puberty till PHA and then declined. Conclusion: Sex disparity in height growth and BP change among school-age children and adolescents is persistent and significant and the change of BP is highly synchronized in time with the increase of height.

Abstract
The frequency of infection of duck circovirus (DuCV) in Anhui province, China is not well-characterized. Therefore, in this study, we collected 69 samples from sick ducks and tested them for the presence of DuCV by conventional polymerase chain reaction (PCR) analysis. The complete viral genomes of five DuCV strains from five different cities were randomly selected, amplified via PCR, sequenced, and subjected to recombination analysis. The five DuCV genomes were named as AHAU9, AHAU25, AHAU28, AHAU37, and AHAUHQ. We found that 36.2 % of the ducks were infected with DuCV. The five DuCV strains had genome lengths ranging from 1987 to 1995 nucleotides, with a sequence similarity of 81.8-98.2 %. Among them, AHAU28, AHAU37, and AHAUHQ were closely related to the reference strain YF180403, GX1105 strain, and wd2015028 of DuCV, respectively. AHAU9 and AHAU25 were found to belong to a new DuCV subtype, DuCV-1d. Moreover, recombination analysis showed that the DuCV-1d subtype strains had the same recombination pattern. These results improve the understanding of the frequency of DuCV infection in Anhui province. Our findings may be useful for preventing and controlling the spread of DuCV.

Abstract
Objective: The study intends to identify gap in HIV/AIDS awareness dissemination between the official channel delivery and the needs of adolescents. Methods: We crawled all the HIV/AIDS queries from "Baidu zhidao" till June 11st, 2018. "Baidu zhidao" inquiry and information form official public service announcement (abbreviated for "official delivery" hereafter) were the data source for comparative analysis. We categorized the text data into four kinds, "prevention", "testing and treatment", "symptoms and infection" and "legalization and policies" according to official categorization. Word segmentation was used for text mining and word frequency statistics, as well word cloud was used for word frequency visualization (all based on a comparison after removing the useless words). Results: Of the official delivery, the proportion of prevention category accounted for 32.3% (n=162) (ranks 1st), and the proportion of legalization and policies category was 14.1% (n=71). While among the "Baidu zhidao" inquiry information, the proportion of testing and treatment category accounted for 51.7% (n=51 264), and the proportion of prevention category accounted for 11.4% (n=11 272). The frequencies of same terms/ repeated terms of two channels accounted for 60% (59.3%-63.9%) of each category among the official delivery, of which, the proportion of interest terms comparatively less and more diverse in "Baidu zhidao" inquiries. The proportion of the terms frequency of each category was about 45% in "prevention, testing and treatment", 34.3% (n=14 781) in "symptoms and infection" and 17.0% (n=5 744) in "legalization and policies", respectively. Conclusion: A big gap was identified between the available official source and inquiries' term, especially word frequency discrepancy between "legalization and policies" and "prevention" categories. It underscore the necessity for the official channel to address the needs and interests of adolescents in the future.

Abstract
Objective: To understand the prevalence of asthma and its variation over time in children aged 0-14 years in China. Methods: The studies on the prevalence of asthma in children in China were systematically retrieved from China National Knowledge Infrastructure (CNKI), WanFang Data, China Science and Technology Journal Database (VIP) and PubMed databases. The search time was up to June 2019, and the study site was located in the asthma surveillance cities. Random effect model was used to calculate the combined prevalence of asthma and its 95% confidence interval (CI). The subgroup analysis was conducted by period, sex and region. All analyses were performed by using Stata 15.1 and R Studio software. Results: Among 2 624 articles, 67 met the eligibility criteria, and the survey time was from 1989 to 2015. A total of 1 661 076 children were involved and 40 737 asthma cases were confirmed from 26 provinces, municipalities and autonomous regions. The prevalence of asthma varied greatly among different studies, ranging from 0.5% to 9.82%. Meta-analysis showed that the combined prevalence of asthma in Chinese children aged 0-14 was 2.6% (95%CI: 2.1%-3.1%), about 3.2% (95%CI: 2.6%-3.8%) for boys and 1.9% (95%CI: 1.6%-2.3%) for girls. The subgroup analysis showed a significant variation of the prevalence over different years, genders and regions (P<0.05). The prevalence of asthma in boys was consistently higher than that of girls. The overall prevalence of asthma showed an upward trend. Before 2010, the prevalence of asthma in the eastern region was higher than that in the central and western regions. The prevalence of asthma across regions showed a significant change and the prevalence of asthma in the central region was significantly higher than that in the eastern and western regions from 2010 to 2015 (P<0.05). Conclusion: The asthma prevalence of children aged 0-14 in China is generally increasing, and the prevalence rate of boys is higher than that of girls. The prevalence rate in the central region is significantly higher than that in the eastern region from 2010 to 2015, suggesting that those regions should strengthen the early prevention and intervention of asthma and implement a sex-specific information dissemination strategy.

Abstract
Objective: To evaluate the clinical characteristics and prognosis of gallbladder cancer (GBC) patients in China. Methods: This retrospective multicenter cohort study enrolled 3 528 consecutive GBC patients diagnosed between January 2010 to December 2017 in 15 hospitals from 10 provinces. There were 1 345 (38.12%) males and 2 183 (61.88%) females.The age of diagnosis was (63.7±10.8) years old (range: 26 to 99 years old) .There were 213 patients (6.04%) in stage 0 to Ⅰ, whereas 1 059 (30.02%) in stage Ⅱ to Ⅲ, 1 874 (53.12%) in stage Ⅳ, and 382 (10.83%) unavailable. Surgery was performed on 2 255 patients (63.92%) . Three hundred and thirty-six patients received chemotherapy or radiotherapy (9.52%; of which 172 were palliative); 1 101 (31.21%) received only supportive treatment.The patient source, treatment and surgery, pathology, concomitant gallstone, and prognosis were analyzed. Results: Among the 3 528 GBC patients, 959 (27.18%) were from East China, 603 (17.09%) from East-North China, 1 533 (43.45%) from Central China, and 433(12.27%) from West China. Among the 1 578 resectable tumor, 665 (42.14%) underwent radical surgery, 913 (57.86%) underwent surgery that failed to follow the guidelines.Eight hundred and ninety-one (56.46%) patients were diagnosed before surgery, 254 (16.10%) during surgery, and 381 (24.14%) after surgery (time point of diagnosis couldn't be determined in 52 patients) .Among the 1 578 patients with resectable tumor, 759 (48.10%) had concomitant gallstone.Among the 665 patients underwent radical surgery, 69 (10.4%) showed positive resection margin, 510 (76.7%) showed negative resection margin, and 86 (12.9%) unreported margin status.The 5-year overall survival rate (5yOS) for the 3 528-patient cohort was 23.0%.The 5yOS for patients with resectable tumor was 39.6%, for patients with stage ⅣB tumor without surgery was 5.4%, and for patients with stage ⅣB tumor underwent palliative surgery was 4.7%. Conclusions: More than half GBC patients in China are diagnosed in stage Ⅳ.Curative intent surgery is valuable in improving prognosis of resectable GBC.The treatment of GBC needs further standardization.Effective comprehensive treatment for GBC is in urgent need.

Abstract
Objective: To clarify the association between occupational exposure to wood dust and chronic obstructive pulmonary disease risk by a meta-analysis. Methods: A systematic search of the studies was conducted using 3 English databases (Pubmed, Embase, and Cochrane library) and 3 Chinese databases (CNKI, WanFang, and VIP) before March 2019. The following key words was used: 1) wood, 2) hardwood, 3) softwood, 4) saw, 5) dust, 6) chronic obstructive pulmonary disease, 7) chronic obstructive airway disease, 8) lung function. A quality score was evaluated by Newcastle-Ottawa Scale, NOS (Wells, 2012). Pooled effect value with 95% confidence interval (CI) was calculated using fixed-effect model (Heterogeneity test I(2)<25%) or random-effect model (Heterogeneity test I(2)≥25%). Meta-regression was used to explore heterogeneous source. Sensitivity analysis was used to verify the stability of the results. Publication bias was assessed by Egger's test. Fill and trim method was used to correct the pool effect value with 95%CI for studies which wit publication bias. The TSA threshold was calculated by the O'Brien-Fleming loss function in the TSA data. The studies were evaluated based on the accrued information size (AIS) . Results: A total of 9 studies were included in the analysis. The occupational exposure to wood dust was not significantly associated with increased chronic obstructive pulmonary disease risk (ES=1.01, 95%CI: 0.856-1.194). TSA showed that the cumulative Z-value curve neither gone beyond the traditional (Z=1.96) threshold line, nor exceed the TSA threshold, but has reached the expected amount of information. This result was consistent with the meta-analysis. Conclusion: This study does not yet consider that COPD is associated with occupational wood dust exposure.

Abstract
In heavy-fermion compounds, the dual character of f electrons underlies their rich and often exotic properties like fragile heavy quasiparticles, a variety of magnetic orders and unconventional superconductivity. 5f-electron actinide materials provide a rich setting to elucidate the larger and outstanding issue of the competition between magnetic order and Kondo entanglement and, more generally, the interplay among different channels of interactions in correlated electron systems. Here, by using angle-resolved photoemission spectroscopy, we present the detailed electronic structure of USb_{2} and observe two different kinds of nearly flat bands in the antiferromagnetic state of USb_{2}. Polarization-dependent measurements show that these electronic states are derived from 5f orbitals with different characters; in addition, further temperature-dependent measurements reveal that one of them is driven by the Kondo correlations between the 5f electrons and conduction electrons, while the other reflects the dominant role of the magnetic order. Our results on the low-energy electronic excitations of USb_{2} implicate orbital selectivity as an important new ingredient for the competition between Kondo correlations and magnetic order and, by extension, in the rich landscape of quantum phases for strongly correlated f electron systems.

Abstract
Objective: To provide scientific evidence for the prevention and control measures of silicosis by analyzing the epidemiological characteristics of silicosis cases reported in Tianjin city during 2001-2015. Methods: The database of silicosis cases reported in Tianjin from 2001 to 2015 was established and analyzed by SPSS 24.0 software. Results: 2 213 cases of silicosis were reported during 2001~2015 in Tianjin, 2015 of them were new cases, and fewer reports of promoting stage cases and death cases, which were129 and 69 cases. The new cases were increasing by years, mainly stage I silicosis accounting for 99.2%, the years of dust exposure were concentrated from 1970 to 1989, accounting for 69.58%. From 2001 to 2015, the median length of service at the onset of silicosis was 19.30 years, the age of the onset of silicosis is decreasing. The median of onset age in new cases of silicosis was 53.28 years, and increased year by year. There were significant differences in indirect dust working age and diagnostic age in different reporting years. Most cases were distributed in non-mental mineral product industry, and ferrous metal smelting and rolling processing industry. The work types of these cases are various. Conclusion: The increasing incidence of silicosis and the shortening of dust-exposed working years suggest that the form of silicosis hazards is still severe in Tianjin. According to the epidemic characteristics of silicosis, we should strengthen the supervision and management of key industries and special investigation, carry out silicosis census and silicosis screening of dust-removal workers, and take pertinent measures to prevent and control the occurrence of silicosis.

Abstract
Chronic liver disease has caused increasing numbers of deaths worldwide. Fatty liver hemorrhagic syndrome, one of the chronic liver diseases in laying hens, has great similarity to non-alcoholic fatty liver disease (NAFLD) in humans. It is characterized by the pathological accumulation of liver fat. Non-invasive techniques are needed for early identification of fibrosis. As primary de novo lipogenesis in the liver of chicken is similar to that of humans, mature chicken is an ideal animal model for the understanding of NAFLD. This study was aimed to evaluate the relationships between gut microbiota and natural chronic liver disease (i.e., non-alcoholic steatohepatitis [NASH] and fibrosis stages) in a well-characterized laying hen population. One hundred 20-wk-old Hy-Line Brown laying hens were used and fed with basal diets until 52 wk of age. At the end of the experiment, birds were killed for sampling blood, liver, and cecal contents, and then classified by liver histology measurement into different groups. We investigated microbial community structure of cecum using 16S rRNA gene sequencing. Subjects in stage 0 fibrosis without NASH were classified as low NAFLD (Group A), subjects in stage 1-2 fibrosis with mild to moderate NASH were defined as low NASH (Group B), and subjects in stage 3 fibrosis were defined as severe NASH (Group C). The abundance of Firmicutes was reduced in Groups B and C (P < 0.001), whereas opposite results were observed for the abundance of Bacteroidetes. Additionally, the families Bacteroidaceae, Ruminococcaceae Lachnospiraceae, and lactobacillae were significantly different between groups of differing fibrosis stages (P < 0.001), driven entirely by alterations of Bacteroides and lactobacillus and lachnospiraceae genera (P < 0.001), were observed. Results indicated that cecal dysbiosis was linked with the severity of fibrosis and NASH; importantly, increased levels of serum AST, alkaline phosphatase, and uric acid were accompanied with liver fibrosis and NASH severity. Collectively, these data highlight the role of gut-liver axis and associations between the gut microbiota and fibrosis and NASH severity.

Abstract
Objective To perform the separation and confirmation of mixed semen stains with immunological test method, and find a more effective method for the detection of mixed semen stains. Methods The semens of three volunteers were mixed. The mixed semen stains were processed and tested with prostate-specific antigen (PSA) colloidal gold immunoassay strip method, immunomagnetic beads method and laser capture microdissection, respectively. Statistics of the results of STR were gathered and compared with those of a single semen stain. Results After PSA colloidal gold immunoassay strip method testing, the samples showed a purplish red line in the test area and the control area. The results obtained with the immunomagnetic beads method showed a more complete and effective short tandem repeat (STR) sequence. The mixed semen stains were processed with laser capture microdissection and low volume amplified. The results were summarized and superimposed to obtain a complete single typing, which matched the single semen stain typing, with a typing success rate of 84.00%. Single suspect Y-STR typing was obtained with the application of the method above in actual cases, which provided evidence basis for rapid solving of the case. Conclusion The combination of PSA colloidal gold immunoassay strip method, immunomagnetic beads method and laser capture microdissection can be used to separate and confirm the mixed semen stains.

Abstract
Objective: To evaluate the role of anatomical hepatectomy in the treatment of intrahepatic cholangiocarcinoma. Methods: The cases of intrahepatic cholangiocarcinoma who received curative surgery in two hospitals from 2010 to 2015 were analyzed retrospectively. Among the 98 patients enrolled in this study, 55 were male and 43 were female. The median age was 61 years. According to receiving anatomical hepatectomy or not, the 98 cases were divided into two groups: non-anatomical hepatectomy(n=30) and anatomical hepatectomy(n=68). The surgical results were compared between the two groups.Survival curves were plotted by the Kaplan-Meier method and compared by the log-rank test. The influence of each prognostic factor identified by univariate analysis was multivariate analysis by Cox's proportional hazard regression. Results: The duration of surgery was significantly prolonged in the anatomical hepatectomy group((196.4±94.9)minutes vs. (166.2±65.7)minutes, P=0.027), while there was no significant difference in terms of other surgical results such as intraoperative blood transfusion, postoperative morbidity and mortality rate. Compared to non-anatomical hepatectomy, anatomical hepatectomy significantly improved long-term survival results(14 months vs. 11 months)(χ2=4.641, P=0.031). Single variable analysis indicated that tumor differentiation, tumor numbers, T stage, N stage, anatomical hepatectomy and adjuvant therapy significantly affected overall survival. Multivariate analysis demonstrated that tumor numbers(HR=0.522, 95% CI: 0.259-0.974, P=0.042) and anatomical hepatectomy(HR=1.858, 95%CI: 1.092-3.161, P=0.022) were two independent prognostic factors for overall survival. Conclusion: Compared to non-anatomical hepatectomy, anatomical hepatectomy performed for intrahepatic cholangiocarcinoma is not only safe but also beneficial for long-term survival.

Abstract
Objective: To investigate the prevalence on imaging, topographic distribution and risk factors of perivascular space (PVS) in community population. Methods: This study was based on the population of Shunyi Study in China from June 2013 to September 2016. One thousand two hundred and thirty-two stroke free participants older than 35 years, who completed cerebral MRI, were included. Cardiovascular risk factors were assessed by interview, physical examination and blood sample tests. PVS were evaluated on high-resolution 3-dimensional-T1WI, T2WI and FLAIR sequences. On T1WI, PVS were detected according to 3D imaging criteria. The number and anatomic location of large PVS (≥3 mm) were recorded. And severity of PVS was then semiquantitatively graded in both white matter (WM) and basal ganglia (BG). Associations between risk factors and PVS were analyzed by multinominal Logistic regression models and adjusted for age, gender and relevant confounders. Results: Perivascular spaces were observed in the BG or WM in every subject, aged (55±10) years and 37.3% male. Large PVS were detected in 19.0% (460/1 232) of participants. Severity of PVS was found to be strongly associated with age in both basal ganglia (severe versus mild: OR=1.81; 95%CI 1.45-2.27, P<0.01) and white matter (OR=1.39; 95%CI 1.13-1.71, P<0.01), and the proportion of subjects with hypercholesterolemia decreased with the severity of PVS in BG (OR=0.58, P=0.01) . The present of large PVS was found to be associated with age(present versus absent: OR=1.03, 95%CI 1.02-1.05, P<0.01) and ApoE ε4 carrier genotype(OR=1.53, 95%CI 1.01-2.23, P=0.04). Conclusions: Perivascular spaces are always detected in the BG or WM in elderly people, and large PVS are also prevalent in community-based population. The risk factors are different due to distribution and size, and may depend on anatomic or pathologic characteristics.

Abstract
Focused ultrasound phased array systems have attracted increased attention for brain therapy applications. However, such systems currently lack a direct and real-time method to intraoperatively monitor ultrasound pressure distribution for securing treatment. This study proposes a dual-mode ultrasound phased array system design to support transmit/receive operations for concurrent ultrasound exposure and backscattered focal beam reconstruction through a spherically focused ultrasound array. A 256-channel ultrasound transmission system was used to transmit focused ultrasonic energy (full 256 channels), with an extended implementation of multiple-channel receiving function (up to 64 channels) using the same 256-channel ultrasound array. A coherent backscatter-received beam formation algorithm was implemented to map the point spread function (PSF) and focal beam distribution under a free-field/transcranial environment setup, with the backscattering generated from a strong scatterer (a point reflector or a microbubble-perfused tube) or a weakly scattered tissue-mimicking graphite phantom. Our results showed that PSF and focal beam can be successfully reconstructed and visualized in free-field conditions and can also be transcranially reconstructed following skull-induced aberration correction. In vivo experiments were conducted to demonstrate its capability to preoperatively and semiquantitatively map a focal beam to guide blood-brain barrier opening. The proposed system may have potential for real-time guidance of ultrasound brain intervention, and may facilitate the design of a dual-mode ultrasound phased array for brain therapeutic applications.

Abstract
High-intensity focused ultrasound (HIFU) has demonstrated the capacity to be used for local thermal ablation in clinical surgery; however, relying solely on conventional ultrasound B-mode imaging to monitor HIFU thermal ablation and determine ablation levels remains a challenge. Here, we experimentally demonstrate the ability to use Nakagami imaging to monitor HIFU-induced thermal lesions in porcine livers ex vivo. Ultrasonic Nakagami imaging has been proven to be able to characterize tissues with different scatterer concentrations and distributions. The pathological sections from HIFU thermally ablated porcine liver tissues reveal that normal and denatured tissues significantly differ in scatterer concentration and distribution. Therefore, we believe that Nakagami imaging can be used to monitor thermal ablation by tracing Nakagami parameter changes in liver tissues. The ex vivo porcine liver experiments were performed using a homemade HIFU device synchronized with a commercial diagnostic ultrasound scanner to obtain the ultrasound envelope data before and after thermal ablation. These data were used to evaluate the performance of thermal lesion characterization using Nakagami imaging and were compared with those derived from conventional B-mode imaging. Experimental results showed that Nakagami imaging can be used to identify thermal lesions, which are difficult to visualize using conventional B-mode imaging because there is no apparent bubble formation. In cases with apparent bubble formation, Nakagami imaging could provide a more accurate estimation of lesion size and position. In addition, the Nakagami imaging algorithm is characterized by low computational complexity, which means it can be easily integrated as postprocessing for existing array imaging systems.

Abstract
This study was to investigate expression levels and functional activities of histone deacetylases (HDACs) with potential therapeutic targets selected in animal model of allergic asthma. Mice were sensitized and then challenged with saline (control) or ovalbumin (OVA) for 8 weeks. Airway resistance was determined by increasing concentrations of acetyl-β-methacholine chloride (0 - 50 mg/ml). The number of cells and cytokine production in bronchoalveolar lavage fluid (BALF) were determined by ELISA. Pathological changes of lung specimens were examined by histochemical staining methods under the light microscope. Expression and quantification of HDACs in lungs were measured using immunohistochemistry and Western blotting analysis. HDAC activity was identified using colorimetric and fluorometric methods. The OVA-treated mice had a significant enhancement in airway resistance with a large number of cells and increased interleukin (IL)-4 and -5 levels in BALF. Morphologically, an infiltration of inflammatory cells into epithelial layer with mucus accumulation and subepithelial fibrosis were seen in the OVA-exposed lungs. The expression levels for HDAC1, HDAC5, HDAC6, and HDAC8 were significantly elevated with weak induction of HDAC 2-4, which was identical with their catalytic activities detected in the lungs. In contrast, HDAC1 and HDAC5 activities were higher than others in the lungs. Individual HDACs are differently regulated in expression levels and functional activities in animal model of allergic asthma. Selective targeting of HDAC1/5 offers an opportunity to improve therapeutic effects of the disease.
