Abstract
Objective: To investigate the efficacy and tolerability of Polatuzumab vedotin+rituximab±bendamustine (Pola-(B)R) in relapse/refractory diffuse large B cell lymphoma (R/R DLBCL) patients. Methods: The clinical data of 21 patients enrolled in Chinese Pola compassionate use program (CUP) in 4 centers from November 2019 to August 2020 were collected. There were 15 males and 6 females, and the median age was 56 years (ranged 25-76 years). Of the patients, 10 cases received Pola-BR regimen and the other 11 received Pola-R. Their clinical features, regimens, efficacy, and adverse events (AEs) were retrospectively analyzed. Results: Twenty-one patients with at least one efficacy evaluation were included. At data analysis cut-off point (12 Aug. 2020), the best overall response (BOR) rate was 81.0% (17/21) and the complete response (CR) rate was 19.0% (4/21). Kaplan-Meier survival estimation was performed, at a median follow-up of 54 days, three patients (14.3%) had disease progressed, and 18 patients (85.7%) were censored; the median progression-free survival (mPFS) was estimated to be 148 days. The incidence of adverse effects (AEs) of any grade was higher in Pola-BR group than Pola-R group (80.0% vs 63.6%). However, the incidence of grade 3-4 AEs were close in the two groups (30.0% vs 29.3%). The most common hematological toxicities were thrombocytopenia (28.6%, 6/21), neutropenia (28.6%, 6/21) and anemia (14.3%, 3/21), respectively. One patient with pneumonia and 1 patient with hemophagocytic syndrome recovered after symptomatic treatment. No peripheral neuropathy of grade≥2 was observed. Conclusions: The preliminary data suggested that, for heavily treated Chinese R/R DLBCL, the Pola-(B)R regimen still achieves promising efficacy and tolerable safety.

Abstract
In this work, a high-order gas kinetic flux solver (GKFS) is developed for simulation of two-dimensional (2D) compressible flows. Different from the conventional gas kinetic scheme, which uses the local integral solution to the Boltzmann equation to reconstruct the numerical fluxes of macroscopic governing equations, the GKFS evaluates the numerical fluxes by the local asymptotic solution to the Boltzmann equation. This local asymptotic solution consists of the equilibrium distribution function and its substantial derivative at the cell interface. To achieve high-order accuracy in the simulation, the substantial derivative is discretized by a difference scheme with second-order accuracy in time and fourth-order accuracy in space, which results in a polynomial of the equilibrium distribution function at different locations and time levels. The Taylor series expansion is then introduced to simplify this polynomial. As a result, a simple high-order accurate local asymptotic solution to the Boltzmann equation is obtained and the numerical fluxes of macroscopic governing equations are given explicitly. A series of numerical examples are presented to validate the accuracy and capability of the developed high-order GKFS. Numerical results demonstrate that the high-order GKFS can achieve the desired accuracy on both the quadrilateral mesh and the triangular mesh and it outperforms the second-order counterpart.

Abstract
The anti-tumor mechanism of tumor treating fields (TTFields) is mainly through interfering with the dynamics of microtubule subunits in mitosis,which blocks the normal process of cell division and eventually leads to cell death.In recent years,relevant studies have found that TTFields still have immunological,molecular biological and other related anti-tumor mechanisms,and can induce reversible increase of cell membrane and blood-brain barrier permeability,which plays a synergistic role in combination with anti-tumor drugs.With the development of multi-system research,the specific treatment frequency,time and field strength of TTFields in different tumor treatments will be revealed.These research progress will further expand the application field of TTFields and benefit more patients.

Abstract
Objective: To analyze the compliance and related factors of low-dose computed tomography (LDCT) screening among the high-risk population of lung cancer in three provinces participating in the cancer early diagnosis and early treatment program in urban areas of China. Methods: From October 2017 to October 2018, 17 983 people aged between 40 and 74 years old at high risk of lung cancer were recruited from Zhejiang, Anhui and Liaoning provinces. The basic demographic characteristics, living habits, history of the disease and family history of cancer were collected by using a cancer risk assessment questionnaire, and the data of participants examined by LDCT were obtained from the hospitals participating in the program. The screening compliance was quantified by the screening participation rate, and it was calculated as the proportion of participants completing LDCT scan among high-risk population. The related factors of LDCT screening compliance were analyzed by using a multivariate logistic regression model. Results: The age of 17 983 participants was (56.52±8.22) years old. Males accounted for 51.9% (N=9 332), and 69.5% (N=12 495) had ever smoked, including former smokers and current smokers. A total of 6 269 participants were screened by LDCT, and the screening participation rate was 34.86%. The results of multivariate logistic regression analysis showed that the age group of 50 to 69 years old, female, passive smokers, alcohol consumption, family history of lung cancer and history of chronic respiratory diseases were more likely to be screened by LDCT, while the compliance of LDCT screening in current smokers was low. Conclusions: The LDCT screening compliance of the high-risk population of lung cancer in urban areas of China still needs to be improved. Age, sex, smoking, drinking, family history of lung cancer and history of chronic respiratory disease are associated with screening compliance.

Abstract
Objective: To understand the influence and lag effect of meteorological factors on the incidence of hand, foot and mouth disease (HFMD) in Shijiazhuang. Methods: The daily incidence data of HFMD in Shijiazhuang during 2017-2019 were collected from Chinese Information System for Disease Control and Prevention. The hourly meteorological data were collected form meteorological stations of Shijiazhuang of Chinese meteorological data network. The distributed lag nonlinear model was built for statistical analysis by software R 3.6.2. Results: When the daily average temperature was 15-26 ℃, the risk of incidence of HFMD increased at lag 3-6 days. However, the risk was highest when the temperature was 25 ℃ at lag 3 days (RR=1.03,95%CI:1.00-1.06). When the daily average relative humidity was more than 80%, the risk of incidence of HFMD increased at lag 5-18 days. However, the risk was highest at lag 9 days (RR=1.04, 95%CI: 1.02-1.06).When the daily average air pressure ranged from 999 hPa to 1 007 hPa, the risk of incidence of HFMD increased at lag 5-8 days. However, the risk was highest at lag 6 days (RR=1.01, 95%CI: 1.00-1.02).When the daily average precipitation ranged from 15 to 32 mm, the risk of incidence of HFMD increased at lag 3-18 days. However, the risk was highest at lag 6 days (RR=1.11, 95%CI: 1.02-1.19). Conclusions: Meteorological factors increased the risk of incidence of HFMD such as higher daily average temperature (15-26 ℃), higher daily average humidity (>80%), lower daily average air pressure (999-1 007 hPa) and higher daily average precipitation (15-32 mm) in Shijiazhuang during 2017-2019. They were all correlated with the incidence of HFMD with certain lag days. It is suggested to use these meteorological indicators for the early warning of HFMD.

Abstract
Celiac disease is an autoimmune disorder triggered by toxic peptides derived from incompletely digested glutens in the stomach. Peptidases that can digest the toxic peptides may formulate an oral enzyme therapy to improve the patients’ health condition. Bga1903 is a serine endopeptidase secreted by Burkholderia gladioli. The preproprotein of Bga1903 consists of an N-terminal signal peptide, a propeptide region, and an enzymatic domain that belongs to the S8 subfamily. Bga1903 could be secreted into the culture medium when it was expressed in E. coli. The purified Bga1903 is capable of hydrolyzing the gluten-derived toxic peptides, such as the 33- and 26-mer peptides, with the preference for the peptide bonds at the carbonyl site of glutamine (P1 position). The kinetic assay of Bga1903 toward the chromogenic substrate Z-HPQ-pNA at 37 °C, pH 7.0, suggests that the values of Km and kcat are 0.44 ± 0.1 mM and 17.8 ± 0.4 s−1, respectively. The addition of Bga1903 in the wort during the fermentation step of beer could help in making gluten-free beer. In summary, Bga1903 is usable to reduce the gluten content in processed foods and represents a good candidate for protein engineering/modification aimed to efficiently digest the gluten at the gastric condition.

Abstract
Objective: To analyze the characteristics of high-grade squamous intraepithelial lesion (HSIL) diagnosed by cervical tissue sampling in postmenopausal women. Methods: A retrospective study was performed on 2 013 patients with HSIL diagnosed by cervical tissue sampling under colposcopy and treated by cervical conization at the First Affiliated Hospital of Zhengzhou University from June 2017 to November 2018, to compare the difference of patients' clinical features, HPV test, liquid-based thin-layer cytology (TCT), performance of colposcopy and biopsy pathology, pathology after cervical conization between 439 postmenopausal patients and 1 574 pre-menopausal patients. Results: (1) Clinical features: the proportion of contact bleeding showed no significant difference between postmenopausal patients and pre-menopausal patients [4.3% (19/439) vs 6.4% (101/1 574); χ²=2.672, P=0.102]. Among the patients with contact bleeding, the proportion of cervical cancer after cervical cone resection was significantly higher in postmenopausal patients compared with pre-menopausal patients [10/19 vs 22.8% (23/101); χ²=7.157, P=0.007]. Among the patients found by routine screening, the proportion of cervical cancer after cervical cone resection was significantly higher in postmenopausal patients compared with pre-menopausal patients [9.0% (38/420) vs 4.3% (63/1 473); χ²=14.726, P<0.01]. The proportion of smooth cervix was higher in postmenopausal patients compared with pre-menopausal patients [63.6% (279/439) vs 35.5% (558/1 574); χ²=111.601, P<0.01]. (2) High-risk HPV infection: there was no significant difference in the high-risk HPV positive rate between the postmenopausal group and the pre-menopausal group [92.0% (404/439) vs 94.4% (1 486/1 574); χ²=3.394, P=0.065]; the HPV 16 infection was the most common type, but there was no significant difference in the HPV 16 infection rate between the two groups [65.8% (289/439) vs 68.0% (1 070/1 574); χ²=0.722, P=0.395]. (3) TCT test: TCT test results included negative for intraepithelial lesion and malignancy (NILM), atypical squamous cell of undetermined signification (ASCUS), atypical squamous cells cannot exclude high-grade lesion (ASC-H), low grade squamous intraepithelial lesion (LSIL), HSIL, compared with the different results of TCT examination, there were not statistically significant difference between postmenopausal and pre-menopausal patients (all P>0.05). (4) The performance of colposcopy: the proportion of insufficient colposcopy and the proportion of cervical type Ⅲ conversion area were higher in postmenopausal patients compared with pre-menopausal patients [87.5% (384/439) vs 32.5% (511/1 574), P<0.01; 80.0% (351/439) vs 21.9% (344/1 574), P<0.01]. The proportion and positive rate of endocervical curettage (ECC) in postmenopausal patients were higher than those in pre-menopausal patients [35.3% (155/439) vs 20.4% (322/1 574), P<0.01; 67.7% (105/155) vs 53.1% (171/322), P=0.003]. The proportion of lesions involving the vaginal wall was higher in postmenopausal patients compared with pre-menopausal patients [5.9% (26/439) vs 1.0% (16/1 574); χ²=40.443, P<0.01]. There was a positive correlation between vaginal wall lesions and cervical lesions in postmenopausal patients (r=0.660, P<0.01). (5) Postoperative pathology: the positive rate of margin and the proportion of pathological escalation after cervical conization were significantly higher in postmenopausal patients compared with pre-menopausal patients [14.6% (64/439) vs 4.8% (75/1 574), 10.9% (48/439) vs 5.5% (86/1 574); P<0.01]. Conclusions: Colposcopy in postmenopausal women is often inadequate, and the cervix is mostly type Ⅲ transformation zone. The lesion in postmenopausal women is more likely to involve the cervical canal and vaginal wall. Clinical attention should be paid to cervical tube curettage and comprehensive examination of the vaginal wall. The high rate of positive margins and a high proportion of pathological upgrading after cervical conization in postmenopausal patients requires further active intervention.

Abstract
Abstract Objective To discuss a new coding method for individual identification based on oral panoramic tomography, analyze the diversity of different coding modules in nonhomologous images and the consistency and the matching rate of the coding indexes of different coding modules in homologous images, and evaluate the application value of the different modules and the new coding method in individual identification. Methods The oral panoramic tomography images of 1 000 patients with permanent teeth were collected retrospectively. Each patient had two images taken at different times (called the Early database and the Late database according to the chronological order). Each image was coded according to the designed coding method. A computer program was designed to compare the diversity of different modules, and calculate the diversity and consistency of different coding modules as well as the matching rate of the coding indexes. Results The diversity of the 4 modules that reflected teeth characteristics was much higher than that of other modules in the same database. The highest diversity was noticed in the module of right mandibular teeth in samples of both databases. The coding consistencies of the 4 modules were all above 50%. Besides, 90.2% of the matching rates of indexes of homologous images were over 80%. Conclusion The 4 modules have higher application value in individual identification, especially the right mandibular teeth. The coding method has a certain value in forensic individual identification.

Abstract
Objective: To evaluate the pathologic findings from biopsy samples to predict the status of nodal metastasis for patients with usual cervical adenocarcinoma. Methods: The 32-pair samples of cervical adenocarcinoma specimens (32 cervical biopsies and 32 hysterectomies with staging) from 2013 to 2019 were selected for retrospective study in Shanghai first Maternal and infant Health Care Hospital Affiliated to Tongji University. The correlation between histopathologic features including necrotic tumor debris (NTD), nuclear grade, mitotic count and pattern-based classification system and the status of lymph node metastasis was evaluated. Results: Tumor invasive patterns of cervical adenocarcinoma, as described previously, could be discerned in hysterectomy/staging specimens, but not in cervical biopsies. Because the biopsy tissues were small, only 14(14/32, 43.8%) cases could be classified according to pattern of invasion, and the concordance rate with resected specimens was 37.5%. NTD (9/19) and grade 3 nuclei (11/19) were positively correlated with invasive pattern C and nodal metastases (P<0.05). Moreover, when NTD and (or) nuclear grade were evaluated at the same time, the sensitivity for type C infiltration was higher. Conclusions: Evaluation of NTD and nuclear grade in biopsies for cervical adenocarcinoma provides good predictive value for lymph node metastasis. It is helpful for patient stratification and management andto avoid unnecessary staging procedures. However, multicenter studies and prospective clinical trials are necessary to confirm the findings before clinical application can be considered.

Abstract
Acute osteofascial compartment syndrome is a series of symptoms and signs caused by acute ischemia of muscles and nerves in osteofascial compartment. If it is not treated in time, it can lead to tissue necrosis. It is rare that it is caused by rodenticide poisoning. Such patients are often difficult to diagnose and treat early and have poor prognosis. In May 2018, a patient with acute osteofascial compartment syndrome caused by anticoagulant rodenticide poisoning was admitted to the Twelfth Hospital of Guangzhou City. After systematic treatment, he finally recovered and discharged. The early manifestations of this patient were mainly coagulation dysfunction, and finally acute osteofascial compartment syndrome. 5 days later, the diagnosis was made, and the operation of incision decompression and vacuum sealing drainage (VSD) was performed.

Abstract
Objective: To investigate the colonscopy screening interval among patients with negative colonscopy. Methods: We selected 14 606 participants who completed the baseline and 3-year or 5-year colonoscopy examinations in the American Prostate, Lung, Colorectal, and Ovarian (PLCO) dataset as the target population. Sociodemographic characteristics (i.e., sex, age, marital status, race, and smoking), lifestyle, family history of cancer, and family history of colorectal cancer were collected. Cochran-Armitage trend analysis was used to examine whether the rate of positive cases (colorectal cancer, advanced adenoma, adenoma, and hyperplastic polyp) was increased with the length of screening interval. We compared the differences in number of detected cases, positive rates, and proportions of 3-year and 5-year screening interval strategies using internal standardization method. Results: The age of the population was (61.9±5.2) years and over half of them were males (54.4%) and 46.2% had family cancer history. The mean screening interval between the first and second endoscopies was (1 639.1±320.9) days. A total of 1 716 cases had positive endoscopic findings. With the screening interval extended, rate of the screened positive cases was also increased (P for trend<0.001). After standardized by the internal standardized population (14 606), 17.99 and 11.57 colorectal cancer cases and 177.37 and 240.35 advanced adenoma cases were detected by 3-year and 5-year screening interval strategies, respectively. Conclusion: Based on the initial screening negative population of colonoscopy in the United States, the 3-year screening interval strategy could detect a relatively large number of colorectal cancer cases, but its health and economic evaluation needs to be further explored.

Abstract
Abstract Schizophrenia is a common disease characterized by thinking obstructions and accompanied by cognitive, emotional and behavioral disorders. Under the control of psychiatric symptoms, patients with schizophrenia may self-injure or impulsively wound others, resulting in public risk and increase in the burden of family and society. In recent years, many studies have shown that the violent behavior of patients with schizophrenia is related to genetic factors. This article reviews the research progress on the relationship between genetic polymorphism and violent behavior of patients with schizophrenia, analyzes the possible mechanism of the correlation between the two, puts forward the limitations of current research and the directions of future research, and provides scientific basis for risk assessment and prevention of violent behavior of patients with schizophrenia.

Abstract
Objective: To understand the epidemiological characteristics of cases with severe and fatal hand, foot, and mouth disease (HFMD) caused by other enterovirus in Hebei province, 2013-2017. Genetic characteristics of the main pathogen cosackie virus A6 (CoxA6) were also analyzed to further clarifying the characteristics and rules of genetic evolution on this virus. Methods: Descriptive epidemiological methods were used to analyze the distribution of severe and fatal cases with HFMD caused by other enterovirus in Hebei, 2013-2017. The VP1 sequences of CoxA6 were phylogenetically analyzed, using the Mega 5.2 software package. Results: A total of 86 severe and fatal cases with HFMD caused by other enterovirus were reported, accounting for 1.12%, comparing to all the HFMD caused by other enterovirus. Cases began to rise in April, and peaked in May-July. 65.12% of the cases occurred in children between 1 and 5 years old. The sex ratio between male and female was 1.39∶1. A total of 93.02% of the cases were children outside the child care settings. A total of 39 positive strains were identified, with positive isolation rate as 45.35%. Phylogenetic analysis on the VP1 sequences of CoxA6 strains in this study revealed that CoxA6 strains belonged to sub-genotypes D3a and D3b. Conclusions: Severe and fatal HFMD cases that caused by other enterovirus in Hebei province was with seasonal feature, consistent with the overall trend of this disease, 2013-2017. No new evolutionary branch appeared in the CoxA6 strain.

Abstract
Objective: To investigate the epidemiological characteristics and current status of surgical management for esophageal cancer in China. Methods: A national database was setup through a network platform. The clinical data of esophageal cancer treated by surgery was collected from 70 major hospitals in China between January 2009 and December 2014. Results: Complete data of 8 181 cases of esophageal cancer patients who underwent surgery were recorded in the database and recruited in the analysis. Among them, 6 052 cases were male and 2 129 were female, the average age was 60.5 years.The epidemiological investigation results showed that 148 cases (1.8%) had history of psychological trauma, 7 527 cases (92.0%) were lower social economic status, 5 072 cases (62.0%) were short of fresh vegetables and fruits, 6 544 cases (80.0%) ate rough food frequently, 3 722 cases (45.5%) drank untreated water directly from lake or river or shallow well, 3 436 cases (42.0%) had a unhealthy eating habit, including habits of eating food fast (507 cases, 6.2%), eating hot food or drinking hot tea/soup (998 cases, 12.2%), eating fried food (1 939 cases, 23.7%), 4 410 cases (53.9%) had the habits of smoking cigarettes and 2 822 cases (34.5%) drank white wine frequently.The pathological results showed that 7 813 cases (95.5%) were squamous cell carcinoma, 267 cases were adenocarcinoma (3.3%), 25 cases were adenosquamous cell carcinoma (0.3%) and 50 cases were small cell carcinoma (0.6%). A total of 1 800 cases (22.0%) received preoperative neoadjuvant therapy due to locally advanced disease or difficulty of resection. The esophagectomies were performed through left thoracotomy approach in 5 870 cases (71.8%), through right chest approach in 2 215 cases (27.1%), and the remain 96 cases (1.2%) received surgery though other approaches.A total of 8 001 cases (97.8%) underwent radical resection, the other 180 cases (2.2%) received palliative resection. The 30-day postoperative mortality rate was 0.5%, the overall ≥ grade Ⅱ postoperative complication rate was 11.6% (951 cases). The 1-yr, 3-yr, and 5-yr overall actual survival rates were 82.6%, 61.6%, and 52.9%, respectively. Conclusions: The data analysis of the national database for esophageal cancer shows that bad eating habits or eating rough food without enough nutrients, lower social and economic status, drinking white wine and smoking cigarettes frequently may be correlated with tumorigenesis of esophageal cancer. However, strong evidences produced by prospective observation studies are needed. Overall, the long-term survival of esophageal cancer patients has been improved gradually due to the application of advanced surgical techniques and reasonable multimodality treatment.

Abstract
Objective: The aim of present study is to analyze clinical and laboratory features of mixed connective tissue disease (MCTD)-associated trigeminal neuropathy (TN). Methods: Clinical records of 12 cases of MCTD complicated with TN diagnosed in Peking University People's Hospital from January 2008 to October 2019 were analyzed retrospectively. Results: The present study included 12 cases, 1 males and 11 females, average age was(40±13)years. TN was developed before the diagosis of MCTD in 1 case. TN and MCTD were occurred simutaneously in 1 case. Raynaud phenomenon (12 cases), arthritis (10cases), edema of fingers (9cases), myositis (6 cases), and pulmonary involvement (11cases) were main cinical feature of MCTD-associate TN. Antinuclear antibody (ANA) and high titer anti-U1-RNP antibody could be detected in serum of all patients. Elevated erythrocyte sedimentation rate (ESR) and creatine kinase were found in serum of 7cases and 5cases, respectively. Blink reflex tests were positive in 6 cases. Neurological symptoms improve slowly without any progress by using glucocorticoid combined immunosuppressants or intravenous gamma globulin. Conclusions: TN is often associted with actived MCTD. Positive ANA and anti-U1-RNP antibody were common in MCTD-associated TN. Blink reflex test is essential to diagnose MCTD-associated TN. Intensive treatment of MCTD contributes to control the progress of TN.

Abstract
We report constraints on the dark photon effective kinetic mixing parameter (κ) with data taken from two p-type point-contact germanium detectors of the CDEX-10 experiment at the China Jinping Underground Laboratory. The 90% confidence level upper limits on κ of solar dark photon from 205.4 kg-day exposure are derived, probing new parameter space with masses (m_{V}) from 10 to 300 eV/c^{2} in direct detection experiments. Considering dark photon as the cosmological dark matter, limits at 90% confidence level with m_{V} from 0.1 to 4.0 keV/c^{2} are set from 449.6 kg-day data, with a minimum of κ=1.3×10^{-15} at m_{V}=200 eV/c^{2}.

Abstract
BACKGROUND AND PURPOSE Cancer is a frequent finding in ischaemic stroke patients. The frequency of cancer amongst participants in the NAVIGATE ESUS randomized trial and the distribution of outcome events during treatment with aspirin and rivaroxaban were investigated. METHODS Trial participation required a recent embolic stroke of undetermined source. Patients' history of cancer was recorded at the time of study entry. During a mean follow-up of 11 months, the effects of aspirin and rivaroxaban treatment on recurrent ischaemic stroke, major bleeding and all-cause mortality were compared between patients with cancer and patients without cancer. RESULTS Amongst 7213 randomized patients, 543 (7.5%) had cancer. Of all patients, 3609 were randomized to rivaroxaban [254 (7.0%) with cancer] and 3604 patients to aspirin [289 (8.0%) with cancer]. The annual rate of recurrent ischaemic stroke was 4.5% in non-cancer patients in the rivaroxaban arm and 4.6% in the aspirin arm [hazard ratio (HR) 0.98, 95% confidence interval (CI) 0.78-1.24]. In cancer patients, the rate of recurrent ischaemic stroke was 7.7% in the rivaroxaban arm and 5.4% in the aspirin arm (HR 1.43, 95% CI 0.71-2.87). Amongst cancer patients, the annual rate of major bleeds was non-significantly higher for rivaroxaban than aspirin (2.9% vs. 1.1%; HR 2.57, 95% CI 0.67-9.96; P for interaction 0.95). All-cause mortality was similar in both groups. CONCLUSIONS Our exploratory analyses show that patients with embolic stroke of undetermined source and a history of cancer had similar rates of recurrent ischaemic strokes and all-cause mortality during aspirin and rivaroxaban treatments and that aspirin appeared safer than rivaroxaban in cancer patients regarding major bleeds. www.clinicaltrials.gov (NCT02313909).
