Abstract
BACKGROUND Pulmonary hypertension (PH) is a common but rarely recognized comorbidity of multiple myeloma (MM) patients, while its prognostic significance for MM has been rarely reported. METHODS We retrospectively analyzed the clinical characteristics and prognostic value of baseline echocardiography-defined PH in 426 newly diagnosed MM (NDMM) patients. RESULTS Echocardiograph-defined PH was found in 12.7% (54/426) of NDMM patients, associated with older age, anemia, and renal insufficiency, as well as severe diastolic dysfunction and higher BNP and NT-pro-BNP levels. Patients with PH presented with a higher prevalence of atrial fibrillation, while with a similar incidence of thrombosis compared with those without PH. Based on similar treatment regimens and autologous stem cell transplantation (ASCT) rates, patients without PH have deeper and better responses than those with PH (p = 0.002). With the remission of MM, 81.5% of PH was reversible, accompanied by improvement of right ventricular dysfunction and normalization of BNP/NT-pro-BNP levels, while could reoccur at MM relapse. Survival analysis revealed that PH was an adverse prognostic factor, associated with reduced progression-free survival (PFS) (21 vs. 50 months, p < 0.001) and overall survival (OS) (45 vs. 90 months, p = 0.014). Multivariate analysis further verified that baseline PH was an independent predictor for shorter PFS and OS. CONCLUSION In conclusion, echocardiography-defined PH is an adverse prognostic indicator for MM patients and should be routinely evaluated in MM patients at diagnosis to make a precise prognosis.

Abstract
BACKGROUND Selinexor 80 mg combined with low-dose dexamethasone (Sd) demonstrated significant clinical benefit in patients with relapsed/refractory multiple myeloma (RRMM) who had disease refractory to a proteasome inhibitor (PI), an immunomodulator (IMiD), and an anti-CD38 monoclonal antibody based on a global phase II STORM study. The present study, MARCH, addresses China regulatory needs to further validate the data from STORM in Chinese patients with RRMM. METHODS The MARCH study was conducted at 17 sites in China, where eligible Chinese RRMM patients who had disease refractory to PI and IMiD were enrolled. Selinexor 80 mg combined with dexamethasone 20 mg was administered orally on day 1 and day 3 of each week in 4-week cycles. The primary endpoint was the overall response rate (ORR) per an independent review committee, with the null hypothesis of ≤15%. Patients who received at least 1 dose of study treatment were included in the safety population. The pharmacokinetic (PK) profile was characterized by parameter and ethnicity sensitivity analyses. RESULTS A total of 82 patients with RRMM were enrolled in the study, with a median age of 60 years. Of the 82 patients, 55 patients (67.1%) had high-risk cytogenetic abnormalities, defined as one or more of del 17p13, t(4;14), t(14;16), or 1q amplification identified by fluorescence in situ hybridization (FISH); 18 patients (22.0%) had abnormal renal function. Enrolled patients were heavily pre-treated with a median prior regimen number of 5. All 82 patients (100%) were refractory to both PI and IMiD, including 20 patients (24.4%) categorized as triple-class refractory population (refractory to PI, IMiD, and daratumumab). Ten patients (12.2%) had undergone CAR-T therapy. ORR was 29.3% (95% CI 19.7, 40.4) with a median DOR of 4.7 months. The median PFS and OS were 3.7 and 13.2 months, respectively. ORR was 25.0% (95% CI 8.7, 49.1) in the triple-class refractory population. Efficacy was consistent across various subgroups. The most frequent grade 3/4 adverse events (AEs) included anemia (57.3%), thrombocytopenia (51.2%), lymphopenia (42.7%), neutropenia (40.2%), hyponatremia (29.3%), and lung infection (26.8%). Serious AEs were reported in 54.9% of patients. No significant drug accumulation was shown following multiple administrations. No human PK ethnicity difference was identified between Chinese and western patients. CONCLUSIONS With an encouraging ORR, the MARCH study has demonstrated that selinexor combined with low-dose dexamethasone (Sd) delivers meaningful clinical benefit to Chinese patients with RRMM, including triple-class refractory patients. AEs were expected and manageable with supportive care and dose modification. TRIAL REGISTRATION ClinicalTrials.gov, NCT03944057 (May 09, 2019); Chinadrugtrials.org.cn , CTR20190858 (June 05, 2019).

Abstract
Objective: To analyze the repetitive reporting of hepatitis B in Fujian province during 2016-2020, and provide evidence for the improvement of hepatitis B surveillance. Methods: The reporting cards from the China Information System for Disease Control and Prevention were collected and divided into repetitive reporting cards and non-repetitive reporting cards from the report cards collected according to the valid ID number on the cards, and the proportion of repetitive report cards and related factors were analyzed by using software SAS 9.4. Results: A total of 314 551 hepatitis B reporting cards were submitted in Fujian from 2016 to 2020, in which 90.93% (286 020/314 551) were included in the analysis. The repetitive reporting cards accounted for 10.48% (29 982/286 020). The annual proportion of the repetitive reporting cards from 2016 to 2020 was between 2.98% and 3.71%, showing an overall increasing trend year by year (Z=2.26, P=0.024). The proportions of the repetitive reporting cards in 1-5 years were 3.17%, 5.40%, 7.74%, 9.27% and 10.48%, respectively, showing an increase trend with year (Z=128.16, P<0.001). The proportions of the repetitive reporting cards in 10 areas of Fujian ranged from 5.44% to 13.48% with significant difference (χ2=2 050.41, P<0.001) and increased with the increase of reported incidence of hepatitis B (Z=26.92, P<0.001). There were significant differences in relationships between repetitive reporting proportion and sex, age and type of the cases between the areas with high incidence and low incidence of hepatitis B. Conclusions: The reported incidence of hepatitis B was seriously affected by the repetitive reporting in Fujian from 2016 to 2020. A cross-year and cross-area surveillance mechanism for hepatitis B should be established and targeted measures should be taken to strengthen the control of the repetitive reporting and improve the surveillance for hepatitis B.

Abstract
Objectives: To evaluate the clinical efficacy of the stratification medical treatment based on the motor complications risk estimation in improving the quality of life, motor symptoms and delaying the motor complications in Parkinson's patients. Methods: Outpatients and inpatients from Xinhua Hospital, Shanghai Jiao Tong University, were recruited between November 2019 and June 2020. The participants were all clinically diagnosed with PD and treated with anti-PD medications, but had no history of motor complications, with the 8-item Parkinson's disease questionnaire summary index (PDQ-8 SI)>18.59. At baseline, the demographic characteristics, PD medical history, levodopa dosage (LD) and levodopa equivalent dosage (LED) were collected, and the evaluation of PDQ-8, Unified Parkinson's disease rating scale (UPDRS)-Ⅱ and Ⅲ, Hoehn and Yahr (H&Y) grade, Hamilton anxiety scale-14 (HAMA-14), Hamilton depression scale-24 (HAMD-24), mini-mental state examination (MMSE), Pittsburgh sleep quality index (PSQI), and Epworth sleepiness scale (ESS) tools was accomplished in all participants. Meanwhile, a Parkinson's disease risk estimation scale for motor complications was used to assess patients' risk of motor complications, and thus the medication was stratified in PD patients accordingly. During the 6-month and 12-month follow-ups, the evaluation of the above-mentioned parameters was repeated in all participants. At the 3-month and 9-month follow-ups, the information of anti-PD medications, the occurrence of motor complications (motor fluctuations and dyskinesia) and adverse drug reactions were recorded, and PDQ-8 was also evaluated. Results: Two hundred and fifty-one patients completed the 1-year follow-up, with 135 males and 116 females. At baseline, the median age of the patients was 66 (60, 71) years and the median PDQ-8 SI was 31.2 (21.9, 40.6). Additionally, 15.9% (40/251) of the patients were at high risk of motor fluctuation, and 7.2% (18/251) were at high risk of dyskinesia. There were significant differences in the age of onset, disease duration, PD treatment duration, the scores of UPDRS-Ⅱ and Ⅲ, H&Y Grade, and PDQ-8 SI among PD patients of different risk groups (all P<0.05). In the 12th month, the median of PDQ-8 SI, Δ PDQ-8 SI and Δ UPDRS-Ⅲ was 12.5 (9.4, 18.8), -15.6 (-21.9, -9.4) and -9(-16, -4), respectively, which was statistically different from that of baseline (all P<0.05). The change of UPDRS-Ⅱ scores in the group with high risk of motor fluctuation was statistically different from that in the groups with low and moderate risk (P<0.05). The changes of PSQI score, LD and LED in the group with high risk of dyskinesia was statistically different from those in the groups with low and moderate risk (all P<0.05). During the follow-up, the incidence of motor fluctuation and dyskinesia was 9.56% (24/251) and 5.97% (15/251), respectively. Conclusion: The stratification medical treatment might have a positive intervention effect on promoting a better quality of life, improving motor symptoms and delaying motor complications in PD patients.

Abstract
BACKGROUND The purpose of this study was to examine the various shapes and record the morphometric data of the glenoid cavity in a Chinese population. MATERIALS AND METHODS A total of 501 scapulae, 247 left and 254 right, were analyzed. We classified the shape of the glenoid cavity as type Ⅰ (pear-shaped), type Ⅱ (oval-shaped), type Ⅲ (teardrop-shaped), type Ⅳ (calabash-shaped) or type Ⅴ (inverted comma-shaped). Four defined parameters, the superior-inferior glenoid diameter (AB), upper anterior-posterior glenoid diameter (CD), lower anterior-posterior glenoid diameter (EF) and glenoid index (GI), were measured, and five shapes were classified via three-dimensional reconstruction. RESULTS The mean AB, CD, EF and GI values of the glenoid were 3.51±0.41 cm, 1.95±0.28 cm, 2.60±0.34 cm, and 1.35±0.12 cm, respectively. The AB value of type Ⅱ glenoid cavities was significantly smaller than that of type Ⅰ and Ⅲ glenoid cavities (P<0.05), but the GI value of type Ⅱ glenoid cavities was larger than that of type Ⅲ cavities (P<0.05). The CD value showed a difference between type Ⅰ and type Ⅲ glenoid cavities (P<0.05). For the EF parameter, the values of type Ⅲ glenoid cavities were significantly larger than those of type Ⅰ and Ⅱ glenoid cavities (P<0.05). CONCLUSIONS Measuring and observing the variety of shapes and sizes of the glenoid cavity in Chinese people is conducive to for better understand its morphological features. This information can also guide surgeons in the design and selection of suitable prostheses for total shoulder arthroplasty in the Chinese population in order to reduce postoperative complications.

Abstract
Objective: To explore the clinical application value of two longitudes three transverses method in the location of the perforator of thoracodorsal artery perforator and deep wound repair. Methods: The retrospectively observational study was conducted. From December 2018 to June 2020, 17 patients with deep wounds who were admitted to the Affiliated Hospital of Zunyi Medical University met the inclusion criteria and were included in this study, including 7 males and 10 females, aged 12 to 72 years. The wound areas of patients after debridement were 7 cm×3 cm to 11 cm×7 cm. Two longitudinal lines were located through the midpoint of the armpit, the posterior superior iliac spine, and the protruding point of the sacroiliac joint, and three transverse lines were located 5, 10, and 15 cm below the midpoint of the armpit between the two longitudinal lines, i.e. two longitudes three transverses method, resulting in two trapezoidal areas. And then the thoracodorsal artery perforators in two trapezoidal areas were explored by the portable Doppler blood flow detector. On this account, a single or lobulated free thoracodorsal artery perforator flap or flap that carrying partial latissimus dorsi muscle, with an area of 7 cm×4 cm to 12 cm×8 cm was designed and harvested to repair the wound. The donor sites were all closed by suturing directly. The number and location of thoracodorsal artery perforators, and the distance from the position where the first perforator (the perforator closest to the axillary apex) exits the muscle to the lateral border of the latissimus dorsi in preoperative localization and intraoperative exploration, the diameter of thoracodorsal artery perforator measured during operation, and the flap types were recorded. The survivals of flaps and appearances of donor sites were followed up. Results: The number and location of thoracodorsal artery perforators located before operation in each patient were consistent with the results of intraoperative exploration. A total of 42 perforators were found in two trapezoidal areas, with 2 or 3 perforators each patient. The perforators were all located in two trapezoid areas, and a stable perforator (the first perforator) was located and detected in the first trapezoidal area. There were averagely 1.47 perforators in the second trapezoidal area. The position where the first perforator exits the muscle was 2.1-3.1 cm away from the lateral border of the latissimus dorsi. The diameters of thoracodorsal artery perforators were 0.4-0.6 mm. In this group, 12 cases were repaired with single thoracodorsal artery perforator flap, 3 cases with lobulated thoracodorsal artery perforator flap, and 2 cases with thoracodorsal artery perforator flap carrying partial latissimus dorsi muscle. The patients were followed up for 6 to 16 months. All the 17 flaps survived with good elasticity, blood circulation, and soft texture. Only linear scar was left in the donor area. Conclusions: The two longitudes three transverses method is helpful to locate the perforator of thoracodorsal artery perforator flap. The method is simple and reliable. The thoracodorsal artery perforator flap designed and harvested based on this method has good clinical effects in repairing deep wound, with minimal donor site damage.

Abstract
The incidence of obesity in our country is increasing year by year. Diet and lifestyle interventions are the most commonly used weight loss measures, but their intervention effects are affected by individual genetics, environment and other factors. Genome-wide association analysis has found many SNPs related to weight loss, and explored the interaction between these loci and diet, intestinal flora and other environmental factors. This article summarizes the study of single nucleotide polymorphisms, the analysis of gene-environment interactions related to diet interventions for weight loss, and the multi-loci analysis and prediction models such as genetic risk scores and machine learning modeling in weight loss, which provides reference for the further application and development of the precise nutrition in medical weight loss.

Abstract
A portion of those infected with SARS-CoV-2 shed the virus and its genetic material in respiratory fluids, saliva, urine, and stool, thus giving the potential to monitor for infections via wastewater. Wastewater surveillance efforts to date have largely assumed that stool shedding has been the primary source of SARS-CoV-2 RNA signal; however, there are increasing questions about the possible contribution of other shedding routes, with implications for wastewater surveillance design and feasibility. In this study we used clinical SARS-CoV-2 RNA shedding data and a Monte Carlo framework to assess the relative contribution of various shedding routes on SARS-CoV-2 RNA loads in wastewater. Stool shedding dominated total SARS-CoV-2 RNA load for community-level surveillance, with mean contributions more than two orders of magnitude greater than other shedding routes. However, RNA loads were more nuanced when considering building-level monitoring efforts designed to identify a single infected individual, where any shedding route could plausibly contribute a detectable signal. The greatest source of model variability was viral load in excreta, suggesting that future modeling efforts may be improved by incorporating specific modeling scenarios with precise SARS-CoV-2 shedding data, and beyond that wastewater surveillance must continue to account for large variability during data analysis and reporting. Importantly, the findings imply that wastewater surveillance at finer spatial scales is not entirely dependent on shedding via feces for sensitive detection of infections thus enlarging the potential use cases of wastewater as a non-intrusive surveillance methodology.

Abstract
Objective: To investigate the clinical features in patients with iridocorneal endothelial (ICE) syndrome. Methods: A retrospective case series study. Data of clinical manifestations of patients with ICE syndrome including clinical subtypes, presenting visual acuity, clinical features and secondary glaucoma were collected from January 2014 to May 2020 in the Eye Hospital, School of Ophthalmology and Optometry, Wenzhou Medical University. The Wald's Chi-square test of generalized estimating equations was performed to analyze the differences in three clinical subtypes. Results: A total of 127 eyes of 114 subjects (64 females and 50 males) were included. Mean±SD age at presentation was (49±13) years. There were 53 patients (46.5%) with Chandler's syndrome (CS), 36 patients (31.6%) with progressive iris atrophy (PIA), 24 patients (21.0%) with Cogan-Reese syndrome (CRS) and one patient (0.9%) with an undetermined subtype. And 101 patients (88.6%) had uniocular ICE syndrome. Approximately 81.7% (49/60), 56.1% (23/41) and 41.7% (10/24) of eyes presented visual acuity <0.3 in patients with CS, PIA and CRS, respectively. Corneal edema was most common in CS (52.5%, 32/61), followed by PIA (29.3%, 12/41) and CRS (20.8%, 5/24). Corectopia was found in 95.8% (23/24) of eyes with CRS, 95.1% (39/41) of eyes with PIA and 78.7% (48/61) of eyes with CS. Polycoria was observed in 29.3% (12/41) of eyes with PIA, 3.3% (2/61) of eyes with CS and 8.3% (2/24) of eyes with CRS. Ectropion uvea was most common in CRS (54.2%, 13/24), followed by 16.4% (10/61) in CS and 12.2% (5/41) in PIA. Glaucoma was found in 94 eyes (74.0%, 94/127). Among them, 60.7% (37/61) of CS, 80.5% (33/41) of PIA and 95.8% (23/24) of CRS had secondary glaucoma. The difference of presenting visual acuity, corneal edema, corectopia, polycoria, ectropion uveae and secondary glaucoma in three clinical subtypes all had statistical significance (Wald χ2=13.87, 10.77, 965.78, 11.45, 15.00, 222.04; all P<0.05). And 86.2% of eyes (81/94) had glaucoma surgeries and 41 eyes (43.6%, 41/94) had the intraocular pressure well controlled with various interventions. Conclusions: ICE syndrome is mostly uniocular and more common in middle-aged patients. CS is the most common clinical subtype with poor presenting visual acuity. About 3/4 of eyes have secondary glaucoma, and the majority of them require surgical interventions, but prognoses are discouraging.

Abstract
With the increase of global chemical production and the aggravation of population exposure and health risks, higher requirements are put forward for chemical toxicity testing and safety evaluation.'Toxicity testing in the 21st century: a vision and a strategy' has greatly promoted the reform of toxicity testing. Toxicity testing in the new era has made great progress by using new models, new methods and new strategies, combined with interdisciplinary and high-tech advantages. While improving the efficiency of chemical toxicity testing, it also realizes more comprehensive, multi-level and high-quality data acquisition and toxicity evaluation, which provides strong support for the exploration of toxicity mode, toxicity mechanism and toxicity pathway. Focusing on the current alternative new methods of toxicity testing, this issue invites many scholars to introduce and summarize high-content analysis, three-dimensional (3D) cell culture technology, Ex vivo test, single cell sequencing and zebrafish experimental methods, in order to promote the leapfrog development of chemical toxicity testing and evaluation in China.

Abstract
In the process of xenobiotic toxicity prediction and risk assessment, in vitro cell culture models possess high practical application value. With the rapid development of biological technologies such as three-dimensional (3D) bio-printing, organoid culture and organ-on-a-chip systems, in vitro cell culture models have made great progress. Sharing the similarities in structure, function and the physiological environment with tissues or organs in vivo, hazard identification and dose-response analysis based on 3D cell culture models provide access to more accurate toxicity data as a theoretical basis for risk assessment and risk management of chemicals. This review summarizes the establishment of three typical 3D cell culture models, i.e., human cell line-based co-culture model, 3D-printed scaffold-based cell culture model and organoids, and their application in toxicity tests of xenobiotics.

Abstract
The toxicity data of chemicals and drugs increases rapidly, while the animal experimental-based tests method could not meet the current demand of health risk assessment. The high-throughput screening techniques based on in vitro alternative models, integrating with computational methods and information technology to establish toxicity tests strategy promises to address this problem. High-content screening (HCS) technology uses automated microscopy and quantitative image platforms to perform multi-parameter and high-throughput phenotypic analysis via a visualization and quantification manner, and to quickly and effectively assess toxicity and prioritization of chemicals, which promotes the development of in vitro toxicity tests and computational toxicology. HCS technology has been included as an important tool for Toxicity Testing in the 21st Century (Tox21) and chemical risk prioritization. Its applications have been widely utilized in the research field of toxicity tests and chemical toxicity mechanisms. In this review, we describe the development of HCS technology, technical points, toxicological applications, and the future directions and challenges of HCS, so as to provide references for the toxicity testing technology and risk assessment methodology.

Abstract
OBJECTIVES This systematic review and meta-analysis aimed to pool the effect size of the association between cognitive frailty and adverse outcomes (e.g., falls, disability, and hospitalization) among older adults. DESIGN Systematic review and meta-analysis. METHODS PubMed, ScienceDirect, and Embase were searched from their respective inceptions to June 1, 2022. We extracted prospective cohort studies that reported the association between cognitive frailty and adverse outcomes. Random or fixed-effects models based on heterogeneity were used to pool the effect sizes of independent associations of cognitive frailty, frailty only, and cognitive impairment only with each adverse outcome. RESULTS Fifteen studies involving 49,122 older adults were included in the meta-analysis. Older adults with cognitive frailty had higher odds ratios (OR) for falls (1.82, 95% confidence interval [CI]: 1.29-2.58), disability (3.17, 95%CI: 2.24-4.48), and hospitalization (1.78, 95%CI: 1.48-2.14) compared with those without frailty and cognitive impairment. Older adults with frailty only demonstrated a high risk for falls (pooled OR 1.76, 95%CI: 1.25-2.48), disability (pooled OR 1.82, 95%CI: 1.43-2.33), and hospitalization (pooled OR 1.64, 95% CI: 1.45-1.85). The influence of cognitive impairment only on adverse outcomes was lower compared with cognitive frailty or frailty. Subgroup analyses showed that those with cognitive frailty (defined by the frailty phenotype plus Mini-Mental State Examination) were at greater risk for developing adverse outcomes. CONCLUSION Our findings indicate that cognitive frailty is an independent risk factor for adverse outcomes (e.g., falls, disability, and hospitalization). Early screening and comprehensive intervention may improve cognitive frailty and reduce the risk for adverse outcomes among older adults.

Abstract
OBJECTIVES Malnutrition is associated with increased incidence of heart failure (HF). Left ventricular (LV) remodeling is one of the most important processes in the occurrence and evolution of HF. However, the association between nutritional status and LV remodeling is not well known. The study aimed to investigate the association between malnutrition and LV remodeling. DESIGN The study was a retrospective observation study. SETTING AND PARTICIPANTS We included patients from the registry of Cardiorenal Improvement study from January 2007 to December 2018 at Guangdong Provincial People's Hospital. MEASUREMENTS The primary endpoint was LV remodeling, defined as an absolute decrease in LV ejection fraction ≥10% after discharge compared with baseline. Nutritional status was assessed by the Controlling Nutritional Status (CONUT) score. Eligible patients were divided into absent-mild malnutrition group (CONUT score ≤4) and moderate-severe malnutrition group (CONUT score >4). Univariable and multivariable logistic regression was performed to verify the association between malnutrition and left ventricular remodeling. RESULTS A total of 7,217 patients (mean age 61.3±10.5 years, 71.7% male) were included in the final analysis, among which 712 (9.9%) had LV remodeling. The incidence of LV remodeling in moderate-severe malnutrition group was significantly higher than that in absent-mild malnutrition group (12.9% vs. 9.5%, p=0.002). In multivariable logistic regression, moderate-severe malnutrition group was significantly associated with 1.69-fold increased risk of LV remodeling after adjusting confounders (OR: 1.69, CI: 1.32-2.16). Similar results were observed in subgroup stratified by age, gender, and coronary artery disease. CONCLUSION Nearly one eighth of patients were classified as moderate-severe malnutrition, 12% of whom had LV remodeling. Moderate-severe malnutrition was associated with 69% increased risk of LV remodeling. Further studies are needed to prospectively evaluate the nutrition-oriented managements on outcomes in LV remodeling.

Abstract
BACKGROUND AND PURPOSE In spastic paraplegia type 5, spinal cord atrophy and white matter signal abnormalities in the brain are the main MR imaging alterations. However, the specific mechanism remains unclear. We explored the microstructural changes occurring in spastic paraplegia type 5 and assessed the relation between MR imaging and clinical data. MATERIALS AND METHODS Seventeen patients with spastic paraplegia type 5 and 17 healthy controls were scanned with DTI and T1 mapping on a 3T MR imaging scanner. Fractional anisotropy, mean diffusivity, radial diffusivity, axial diffusivity, and T1 values were obtained using Tract-Based Spatial Statistics and the Spinal Cord Toolbox. Neurofilament light and myelin basic protein in the CSF were measured. The differences in MR imaging and biochemical data between patients with spastic paraplegia type 5 and healthy controls were compared using the Student t test. RESULTS A widespread reduction of fractional anisotropy values and an elevation of mean diffusivity, T1, and radial diffusivity values were found in most cervical, T4, and T5 spinal cords; corona radiata; optic radiations; and internal capsules in spastic paraplegia type 5. A variation in axial diffusivity values was shown only in C2, C6, and the corona radiata but not in the gray matter. The levels of neurofilament light and myelin basic protein were higher in those with spastic paraplegia type 5 than in healthy controls (myelin basic protein, 3507 [SD, 2291] versus 127 [SD, 219] pg/mL; neurofilament light, 617 [SD, 207] versus 265 [SD, 187] pg/mL; P < .001). No correlation was found between the clinical data and MR imaging-derived measures. CONCLUSIONS Multiparametric MR imaging and biochemical indicators demonstrated that demyelination (mainly) and axonal loss led to the white matter integrity loss without gray matter injury in spastic paraplegia type 5.

Abstract
OBJECTIVES This study aimed to explore the association between number of teeth and cognitive frailty in American older adults. DESIGN Cross-sectional study. SETTING Community. PARTICIPANTS The participants were 1,531 community-dwelling older adults aged 60 or older from the NHANES database. METHODS Frailty was assessed using a 49-item frailty index, with a cut-off value for frailty of more than 0.21. Cognitive dysfunction was evaluated by the Digit-Symbol Coding Test (DSCT), with the cut-off being below the lowest interquartile range (scores ≤37). Cognitive frailty was defined as participants who suffered from both frailty and cognitive dysfunction. Oral health indicators included number of teeth and other factors, such as the presence of gum disease, daily use of dental floss, daily use of mouthwash and self-rated oral health. Multivariable logistic regression models were used to explore the relationship between number of teeth and cognitive frailty. RESULTS The mean age of the total sample was 69.67 (SD=6.60) years, and 52.71% (n=807) were female. Our study suggests there was a negative association between number of teeth and cognitive frailty (OR =0.98,95%CI:0.96-0.99, P=0.044) after controlling for potential confounding factors. In addition, older adults with 20 or more teeth had lower odds of being cognitively frail (OR=0.66,95%CI:0.44-0.99, P=0.046) than individuals who had less than 20 teeth. CONCLUSION This study suggests that older adults who have more teeth are associated with a lower risk of cognitive frailty. This finding highlights the importance of maintaining as many teeth as possible throughout life and into old age. Cohort studies will be required in the future to determine this relationship.

Abstract
Osteoporotic fractures, also known as fragility fractures, are prevalent in the elderly and bring tremendous social burdens. Poor bone quality, weak repair capacity, instability, and high failure rate of internal fixation are main characteristics of osteoporotic fractures. Osteoporotic bone defects are common and need to be repaired by appropriate materials. Proximal humerus, distal radius, tibia plateau, calcaneus, and spine are common osteoporotic fractures with bone defect. Here, the consensus from the Osteoporosis Group of Chinese Orthopaedic Association concentrates on the epidemiology, characters, and management strategies of common osteoporotic fractures with bone defect to standardize clinical practice in bone repair of osteoporotic fractures.

Abstract
Abstract
In this study,90Sr was used as the test radionuclide to characterize the sorption kinetics and effects of initial 90Sr activity and remaining 90Sr in solid concentration were simulated for a near-surface repository. The study focused on the sorption characteristics of radionuclides in unsaturated groundwater environment (or vadose zone) is the important information for investigating the near-surface disposal of intermediate and low-level radioactive waste (ILLW). Moreover, the 90Sr sorption experiments reached equilibrium within 56 h, which fit to the first order sorption kinetic model, and the remaining 90Sr in mudrock samples showed obvious sorption equilibrium hysteresis, which fit to the second order sorption kinetic model. Before reaching the maximum sorption capacity, the sorption rate constant increases with 90Sr increasing; the distribution coefficient (Kd) of 56 h decreases with the remaining 90Sr decreasing. In addition, it showed that the slow sorption process dominated before the sorption reaches equilibrium. In fact, a reliable safety assessment methodology for on-going near-surface repository required a lot of the radionuclides parameters with local environment including the radionuclides sorption/desorption rate constant and maximum sorption capacity.

Abstract
Eight mono- or disaccharide analogues derived from BLM disaccharide, along with the corresponding carbohydate-dye conjugates have been designed and synthesized in this study, aiming at exploring the effect of a gulose residue on the cellular binding/uptake of BLM disaccharide and it possible uptake mechanism. Our evidence is presented indicating that, for the cellular binding/uptake of BLM disaccharide, a gulose residue is an essential subunit but unrelated to its chemical nature. Interestingly, d-gulose-dye conjugate is able to selectively target A549 cancer cells, but l-gulose-dye conjugate fails. Further uptake mechanism studies demonstrate d-gulose-dye derivatives similar to BLM disaccharide-dye ones behave in a temperature- and ATP-dependent manner, and are partly directed by the GLUT1 receptor. Moreover, d-gulose modifying gemcitabine 53a exhibits more potent antitumor activity compared to derivatives 53b-c in which gemcitabine is decorated with other monosaccharides. Taken together, the monosacharide d-gulose conjugate offers a new strategy for solving cytotoxic drugs via the increased tumor targeting in the therapy of lung cancer.

Abstract
In addition to offering methionine, 2-hydroxy-4-methylthiobutyric acid (HMTBa) is also an organic acid and shows excellent bacteriostasis. Therefore, 3 experiments were conducted to determine the influence of drinking water supplemented HMTBa in combination with acidifier on performance, intestinal development, and microflora in broilers. The addition of different concentration (0.02–0.20%) of the blend of HMTBa and other acids significantly reduced the pH of water and exerted antimicrobial activity in dose-dependent manner in vitro. The outcomes from animal trial consisting of the drinking water with blended acidifier at 0.00, 0.05, 0.10, 0.15, and 0.20% indicated that the water with 0.15 or 0.20% acidifier resulted in linear and quadratic higher body weight at 42 d, gain and water consumption during 1 to 42 d (P < 0.05). In experiment 3, responding to graded blended acidifier in drinking water, birds receiving 0.10, 0.15, and 0.20% acidifier decreased the internal pH of gastrointestinal tract and muscle, and exhibited increased duodenal weight, length, villus high, and the ratio of villus high to crypt depth. Drinking water with 0.2% blended acidifier increased the abundance of probiotics (Bacteroidaceae, Ruminococcaceae, and Lachnospiraceae) and decreased the account of pathogenic bacteria such as Desulfovibrionaceae. Alternations in gut microflora were closely related to the metabolism of carbohydrate, amino acid, and vitamins. These findings, therefore, suggest that drinking water with 0.10 to 0.13% the combination HMTBa with acidifier might benefit to intestinal development and gut microbiota, and the subsequent produce a positive effect on the performance of broilers.

Abstract
This study evaluated the effects of selenium (Se) supplementation in maternal and offspring diets on performance and antioxidant capacity of ducklings aged from 0 to 2 wk. A total of 144 female Longyan duck breeders aged 22-wk were allotted into 2 treatments and fed a control diet or a 0.16 mg Se/kg supplemented diet. At 40-wk, 120 offspring from each treatment were divided into 2 groups, with 6 replicates of 10 birds. Using a 2 × 2 factorial design, ducklings from each maternal dietary treatment were assigned to a control diet or a 0.16 mg Se/kg supplemented diet from hatch to 2-wk. Compared with Se-deficient diet, maternal diet supplemented with 0.16 mg Se/kg increased the BW of hatchlings (P < 0.01). There were interactions between maternal and progeny diet with 0.16 mg Se/kg in BW of ducklings aged 2 wk and BW gain (BWG) as ducklings from maternal Se/progeny none treatment had the lightest BW and BWG (P < 0.01). Maternal diet with 0.16 mg Se/kg decreased plasma concentration of uric acid and insulin-like growth factor 1 (P < 0.01), and progeny diet supplemented with 0.16 mg Se/kg increased the activities of glutathione peroxidase 3 (GPx3) in plasma and glutathione peroxidase 1 in erythrocyte (P < 0.01). Maternal diet with 0.16 mg Se/kg increased (P < 0.05) the hepatic activity of total superoxide dismutase (T-SOD). Progeny diet supplemented with 0.16 mg Se/kg increased (P < 0.01) hepatic activity of GPx3 and decreased (P < 0.01) the hepatic concentration of malondialdehyde. Interactions were detected between maternal and progeny diet with 0.16 mg Se/kg in hepatic activity of T-SOD and maternal and progeny diet supplemented with Se displayed the highest hepatic activity of T-SOD (P < 0.05). Overall, Se supplementation in the diet of duck breeders and offspring increased the antioxidant capacity of ducklings. Maternal Se supplementation increased the BW of hatchlings, whereas maternal and progeny dietary Se supplementation did not affect the BWG of ducklings aged from 0 to 2 wk. Se supplementation with additional 0.16 mg/kg in the diet of duck breeders and offspring displayed beneficial effects particularly on the antioxidant capacity in ducklings.

Abstract
We retrospectively studied the impact of cytogenetic abnormalities in 328 consecutive newly diagnosed multiple myeloma (MM) patients. High-risk cytogenetic abnormalities (HRCAs) included del (17p), amp/gain (1q21), t(4;14), and t(14;16). We defined a standard-risk group by the absence of HRCA, an intermediate-risk group with one HRCA, and a high-risk (HiR) group with at least two HRCAs. The HiR group constituted 14.3% of patients and was associated with a median overall survival (OS) of 28.6 months and progression-free survival (PFS) of 14.0 months. Moreover, the HiR group predicted poor outcomes for OS and PFS in multivariate analyses, and bortezomib prolongation to nine cycles could not bring additional benefit to this entity, suggesting the necessity of more effective therapies for these patients. Furthermore, we confirmed the independent prognostic impact of amp 1q21 in this real-world study.

Abstract
When expressing streptavidin recombinant polypeptide on magnetosomes (called bacterial magnetic nanoparticles, or BMPs), the presence of endogenous bacterial biotin might be detrimental. In the study, the streptavidin monomer fragment (S1-116) was fused with the intein N-terminal (termed precursor S1-116-IN), and S1-116-IN was expressed in E. coli (BL21). Meanwhile, the SA117-160 fragment was fused with the C-terminal intein, and then this chimeric polypeptide was expressed on magnetosomes by fusion with magnetosome membrance protein MamF. In the in vitro protein splicing system, the purified engineered magnetosomes (BMP-SA117-160-IC) and the S1-116-IN precursor were mixed. Intein-mediated trans-splicing reaction was induced to produce the functional magnetic beads BMP-SA. Our results indicate that intein-mediated protein trans-splicing may lead to efficient synthesis of the recombinant streptavidin on the magnetosomes, showing its promising potential to produce other functional magnetic nanoparticles.

Abstract
Objective: To investigate the prevalence and associated factors of hyperkalemia in dialysis patients. Methods: Patients underwent hemodialysis (HD) and peritoneal dialysis (PD) from multi-center databases were recruited from January 2017 to December 2019, and those aged ≥18 years and with dialysis duration ≥3 months were included to analyze the prevalence and related factors of hyperkalemia. Results: A total of 12 364 patients were enrolled in the study, and 6 836 cases were men. The average age of the patients was (51±15) years. Among these patients, 4 230 cases underwent HD while 8 134 received PD. Hyperkalemia was detected in 20.7% (2 554/12 364) of the patients while hypokalemia was found in 17.0%(2 102/12 364) of the patients. Multivariate logistic regression showed that HD (OR=2.25, 95%CI: 1.54-3.30), diabetes mellitus (DM) (OR=1.65, 95%CI: 1.17-2.32), high body mass index (BMI) (OR=1.06, 95%CI: 1.03-1.09), high levels of serum albumin (OR=1.04, 95%CI: 1.01-1.07) and phosphorus (OR=3.12, 95%CI: 2.44-4.00), low levels of serum bicarbonate (OR=0.89, 95%CI: 0.87-0.92), triglycerides (OR=0.76, 95%CI: 0.68-0.85) and creatinine (OR=0.95, 95%CI: 0.90-0.99), usage of angiotensin converting enzyme inhibitor/Angiotensin Ⅱ receptor antagonist (ACEI/ARB, OR=1.38, 95%CI: 1.11-1.72) and beta-blocker (OR=1.32, 95%CI: 1.07-1.64) were associated with hyperkalemia. Conclusions: Hyperkalemia occurred in 20.7% of the dialysis patients. HD, DM, high BMI, high levels of serum albumin and phosphorus, low levels of serum bicarbonate, triglycerides and creatinine, use of ACEI/ARB were associated with hyperkalemia.

Abstract
Diacylglycerol acyltransferase (DGAT) is a crucial enzyme in the triacylglycerol (TAG) biosynthesis pathway. The oleaginous fungus Mortierella alpina can accumulate large amounts of arachidonic acid (ARA, C20:4) in the form of TAG. Therefore, it is important to study the functional characteristics of its DGAT. Two putative genes MaDGAT1A/1B encoding DGAT1 were identified in M. alpina ATCC 32222 genome by sequence alignment. Sequence alignment with identified DGAT1 homologs showed that MaDGAT1A/1B contain seven conserved motifs that are characteristic of the DGAT1 subfamily. Conserved domain analysis showed that both MaDGAT1A and MaDGAT1B belong to the Membrane-bound O-acyltransferases superfamily. The transforming with MaDGAT1A/1B genes could increase the accumulation of TAG in Saccharomyces cerevisiae to 4·47 and 7·48% of dry cell weight, which was 7·3-fold and 12·3-fold of the control group, respectively, but has no effect on the proportion of fatty acids in TAG. This study showed that MaDGAT1A/1B could effectively promote the accumulation of TAG and therefore may be used in metabolic engineering aimed to increase TAG production of oleaginous fungi.

Abstract
BACKGROUND Tinea capitis is still common in developing countries, such as China. Its pathogen spectrum varies across regions and changes over time. OBJECTIVES This study aimed to clarify the current epidemiological characteristics and pathogen spectrum of tinea capitis in China. METHODS A multicentre, prospective descriptive study involving 29 tertiary hospitals in China was conducted. From August 2019 to July 2020, 611 patients with tinea capitis were enrolled. Data concerning demography, risk factors and fungal tests were collected. The pathogens were further identified by morphology or molecular sequencing when necessary in the central laboratory. RESULTS Among all enrolled patients, 74.1% of the cases were 2- to 8-year-olds. The children with tinea capitis were mainly boys (56.2%) and more likely to have an animal contact history (57.4% vs. 35.3%, P = 0.012) and zoophilic dermatophyte infection (73.5%). The adults were mainly females (83.3%) and more likely to have anthropophilic agent infection (53.5%). The most common pathogen was zoophilic Microsporum canis (354, 65.2%), followed by anthropophilic Trichophyton violaceum (74, 13.6%). In contrast to the eastern, western and northeastern regions where zoophilic M. canis predominated, anthropophilic T. violaceum predominated in central China (69.2%, P < 0.0001), where the patients had the most tinea at other sites (20.3%) and dermatophytosis contact (25.9%) with the least animal contact (38.8%). Microsporum ferrugineum was the most common anthropophilic agent in the western area, especially in Xinjiang Province. CONCLUSIONS Boys aged approximately 5 years were mainly affected. Dermatologists are advised to pay more attention to the different transmission routes and pathogen spectra in different age groups from different regions.

Abstract
Purpose/Objective(s) Premature discontinuation of radiation therapy (RT) is a significant challenge portending inferior outcomes, particularly with curative intent RT. This study measures the impact of the COVID-19 pandemic compared to prior treatment terminations (TTs) from a multi-institutional health system in the New York Metropolitan area. Materials/Methods TT data was collected from the internal quality assurance records of a multicenter radiation oncology department for the September 2019-February 2020 pre-pandemic interval (BP) and the March 2020-August 2020 post-pandemic interval (AP). We measured aggregate and monthly CT simulations (CT sims), TTs, and terminations with zero fractions of radiation given (0Fx), the latter stratified by palliative vs. curative intent (0Fx-P vs. 0Fx-C). AP TTs attributed to COVID-19 anxiety were also obtained. The data were analyzed as aggregate ratios with monthly weighting of TTs/CT sims, 0Fx/CT sims, and 0Fx/TTs. Ratio statistics were employed and 95% confidence intervals generated. 0Fx-P and 0Fx-C were tested for association with BP and AP by chi-square analysis. Results For BP and AP respectively: TTs/CT sims were 8.1% (95% CI 5.2%-11.0%) and 11.2% (95% CI 9.2%-13.3%); 0Fx/CT sims were 1.4% (95% CI 0.16%-2.70%) and 2.5% (95% CI 1.49%-3.6%); 0Fx/TTs were 15.8% (95% CI 6.35%-25.21%) and 22% (95% CI 16.0%-27.9%). The association of 0Fx-P and 0Fx-C with BP and AP yielded chi-square = 0.43, P = 0.51. TTs attributed to COVID-19 anxiety comprised 3.9% of TTs in AP. Conclusion The endpoints for TTs in the BP and AP periods in our study cohort were suggestive of a COVID impact on patients discontinuing radiation therapy, but without statistical significance. Given the subtleties of TT dynamics and uncertainties such as the count of COVID-19 anxiety-related terminations, along with a relatively small sample size, it is reasonable to infer that this review was underpowered. Moreover, direct statistical attribution of TTs to COVID understates knock-on effects, e.g., the case of a 0Fx TT that would have occurred regardless of COVID but under the stress of the pandemic exacerbates the harm of the waste of resources. At the patient care level, understanding how COVID affects TT patterns may enable interventions that facilitate completion of care as intended by the treating physician. At the health system level, such understanding may elucidate a plausible mechanism of COVID's cascading downstream influence on oncologic outcomes. Nevertheless, it will require a multi-institutional cohort to quantitatively discern the impact of the pandemic on TT dynamics.

Abstract
Introduction/Objective
Goblet cell adenocarcinoma (formerly goblet cell carcinoid) is a rare tumor almost exclusively involving the appendix. It is an amphicrine tumor consisting of both epithelial and neuroendocrine elements containing goblet cells. In the 2019 WHO classification update, GCC was reclassified as goblet cell adenocarcinoma of the appendix as it is recognized to have predominantly mucin secreting cells and a minor neuroendocrine component.
Methods/Case Report
A 72 year old,morbidly obese male presented with a 2 week history of abdominal pain and bilious vomiting. Imaging revealed a peri-appendiceal abscess. Due to the chronicity of his symptoms, he was treated conservatively with drainage of the abscess and intravenous antibiotics. He responded well and underwent elective laparoscopic appendectomy; at which time, the appendix appeared grossly unremarkable, measuring 5.1 x 0.9 x 0.3 cm with a wall thickness of 0.5 cm. Microscopically small nests and clusters of goblet cells circumferentially invaded dense collagenous stroma in the appendiceal wall. The neoplastic cells had large mucin vacuoles and small basally located nuclei. The cells were positive for CK20, CDX2, CD56, synaptophysin and focally positive for chromogranin. Ki-67 was 10%. CK7 was negative. These tumors are now graded and staged similar to colonic adenocarcinomas according to the 5 th edition of the World Health Organization Classification of Tumors - Digestive System Tumors.
Results (if a Case Study enter NA)
NA
Conclusion
This case demonstrates that this rare tumor may be an incidental finding in an elderly patient presenting with appendicitis; accurate diagnosis of this rare tumor may require submission of the entire appendix for microscopic evaluation.

Abstract
Abstract
Introduction/Objective
Chronic myelomonocytic leukemia (CMML) is a myeloid neoplasm characterized by sustained monocytosis, ranging from cytopenia with a dysplastic subtype to leukocytosis with a proliferative subtype, with a typical mutational profile involving TET2, ASXL1, and SRSF2. Mutation in colony-stimulating factor 3 receptor gene (CSF3R) is commonly associated with chronic neutrophilic leukemia (CNL) but exceedingly rare in CMML, particularly CSF3R T618I (~10 cases described, ~30 cases of CSF3R non-T618I mutations). We report a case of CSF3R T618I mutated CMML and compare the clinicopathologic features to reported CMML cases with and without CSF3R T618I mutations.
Methods/Case Report
A 27-year-old woman presented for evaluation of leukocytosis, sustained monocytosis, and anemia. Peripheral blood (PB) revealed leukocytosis (white cell count 35x109/L), left-shifted and dysplastic neutrophils (myelocytes and metamyelocytes, 5%), absolute and relative monocytosis (7x109/L, 29%), anemia (Hgb 4.3 g/dL), and thrombocytopenia. Bone marrow aspirate and core biopsy demonstrated a hypercellular marrow with increased myeloblasts (~3%, immunophenotypically aberrant by flow cytometry), increased myelomonocytic cells, and multilineage dysplasia, including ring sideroblasts and hypolobated megakaryocytes. Cytogenetic and molecular studies revealed a normal karyotype and mutations in CSF3R T618I, ASXL1, SETBP1, BCORL1, KRAS, and PTPN11. Despite the presence of a CSF3R T618I mutation, CMML was diagnosed given marked monocytosis, left- shifted neutrophils in PB, multilineage dysplasia, and immunophenotypically aberrant myeloblasts.
Results (if a Case Study enter NA)
NA
Conclusion
Our case demonstrates clinicopathological features similar to those of reported CSF3R T618I mutated CMML, i.e., a proliferative subtype and less likely to have co-occurring mutations in TET2 or SRSF2, which is distinct from CSF3R non-T618I mutated CMML; the latter often has a dysplastic subtype and mutational profile of frequent TET2 and SRSF2 mutations, similar to CSF3R unmutated CMML. While additional cases with this unusual mutation need to be studied to arrive at a more definitive conclusion, the CSF3R T618I mutation seems to define a unique proliferative subtype CMML with a distinct mutational profile.

Abstract
Objective: To further clarify the mid-and-long term follow-up results of self-designed tibial periosteum-bone complex transplantation in the treatment of Hepple V osteochondral lesion of the talus(OLTs). Methods: The clinical data of 30 patients with Hepple V OLTs who received treatment in the Sports Medicine Center of the First Affiliated Hospital of Army Military Medical University from October 2011 to January 2019 were analyzed. There were 19 males and 11 females with a mean age of (40±11) years. Patients were treated with autogenous tibial periosteum-bone complex transplantation and were followed up for at least 2 years. The Foot and Ankle Outcome Score (FAOS), American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, the visual analog scale score (VAS) of pain, the simplified symptomatology evaluation (SSE) and imaging results before the operation and at the follow-up were recorded and compared. Results: The cohort were followed-up for a mean of 63.9 months (range 24-110 months). Twenty-nine (96.7%) patients were satisfied with the curative effect. The FAOS score was improved from 53.5±6.2 preoperatively to 88.4±6.6 at the final follow-up (P<0.001). The AOFAS ankle-hindfoot scale improved from 61.6±8.2 preoperatively to 90.8±6.8 at the last follow-up (P<0.001). The VAS score decreased from 4.3±0.2 preoperative to 0.7±0.7 at the last follow-up (P<0.001). The SSE score was poor in 14 cases (46.7%), average in 16 cases (53.3%) before the operation; and it was excellent in 23 cases (76.7%), good in 6 cases (20%), average in 1 case (3.3%) at the last follow-up. Imaging examination showed cystic change cure rate was 83.3%, cartilage defects were completely infilled with repair tissue, which didn't show any signs of degeneration. However, repair tissue showed varying degrees of heterogeneous signal compared to the normal articular cartilage. Conclusion: The autograft of tibial periosteum-bone complex transplantation is a safe and feasible method for the treatment of osteochondral lesion of the talus in Hepple V type, with good mid-and-long term clinical effect.

Abstract
Upright-legged locomotion is a desirable ability for people with paraplegia. This paper introduces a newly developed lightweight powered exoskeleton (LIPE) for level walking and posture transfer of people with paraplegia using a user-centered design concept, which integrates the requirements of practical use, mechanical structure, and control system. The LIPE was evaluated with two subjects through several experimental tasks including kinematics and dynamics analysis in a local hospital. Results of functional evaluation showed that these subjects received the exoskeleton intervention well and the LIPE could provide appropriate gait assistance to the wearer during level walking, it could also help the wearer achieve the posture transfer from sitting to standing or from standing to sitting independently. Moreover, an endurance test also indicated that LIPE allows wearers to use it continuously for a long time. It is lightweight, cost effective, easy to use, and practical for people with paraplegia in their daily lives.

Abstract
Backgroud Primary tonsil diffuse large B cell lymphoma (PT-DLBCL) is an uncommon disease entity. The role of radiation therapy (RT) in PT-DLBCL is debatable in both the pre- and post- rituximab era. The purpose of this study was to evaluate the treatment outcome and establish a prognostic model in PT-DLBCL based on the Surveillance, Epidemiology, and End Results (SEER) database. Materials and methods Data of 1214 PT-DLBCL patients diagnosed between 1975 and 2016 were extracted from SEER 18. The effect of RT was assessed for the entire cohort and subgroups by stages using univariate, multivariate Cox regression analyses and propensity score matching (PSM). Results The entire cohort included 1043 patients with early-stage (ES) PT-DLBCL and 171 patients with advanced-stage (AS) disease. A decreasing trend of RT utilization in the ES cohort after 2002 was observed. 47.4% of patients in ES received RT, whereas 25.1% in AS underwent RT. RT significantly improved overall survival in both univariate (P < 0.001) and multivariate (P = 0.002) analyses. PSM analysis further validated the survival advantage of RT (P = 0.002). A nomogram was established to predict the potential survival benefit. Subgroup analysis revealed RT was significantly associated with overall survival in ES patients of PT-DLBCL (P = 0.001) and in the rituximab era (P = 0.001) but not in those with AS disease (P = 0.241). Conclusions This population-based study encloses the largest sample of PT-DLBCL to date and demonstrates a favorable survival role of RT in early stages rather than advanced stages. The established nomogram helps to identify high risk patients to improve prognosis.

Abstract
Air, crop, and rhizosphere soil samples were collected from e-waste dismantling areas in Taizhou City (Zhejiang Province, China). The mean PBDEs (Polybrominated diphenyl ethers) concentrations in air in the Fengjiang and Binhai areas were 27.8 and 25.1 pg m-3, respectively (no significant difference, P > 0.05). The mean PBDE concentrations in rhizosphere soil from Fengjiang and Binhai were 9.19 × 104 and 1.34 × 103 pg g-1 dry weight, respectively (no significant difference, P > 0.05). The mean PBDE concentrations in the crop samples from Fengjiang and Binhai were 1.38 × 103 and 6.64 × 102 pg g-1 dry weight, respectively (no significant difference, P > 0.05). PBDEs with≥6 bromine atoms (BDEs-153, -154, -183, and -190) were not translocated from the crop roots to other tissues. PBDEs were taken up by crops selectively. The root epidermis effectively prevented PBDEs from entering edible crop parts and kept the PBDE concentrations in edible roots low. PBDEs with≤5 bromine atoms (BDEs-15, -28, -47, -66, -85, -99, and -100) were selectively enriched from the rhizosphere soil into crop roots, but PBDEs with more bromine substituents were not transferred from the rhizosphere soil to the crop roots. PBDEs with≥6 bromine atoms were selectively enriched from the atmosphere into crop leaves. Crop roots and leaves took up PBDEs with ortho bromine substituents more readily than PBDEs with meta bromine substituents because the octanol-water partition coefficients are lower for ortho-brominated than meta-brominated PBDEs.
