Abstract
Background The prognosis of relapsed/refractory multiple myeloma (RRMM) patients with the extramedullary disease was significantly poor. Extramedullary multiple myeloma (EMM) patients gained limited benefits from traditional drugs. Anti-B cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T-cell therapy seems to be a promising approach to treat RRMM patients. However, very few clinical studies are designed for EMM. Our study aimed to compare and assess the safety, efficacy, and pharmacokinetics of anti-BCMA CAR-T cell therapy in EMM and non-EMM. Methods The results from published anti-BCMA CAR-T clinical trials, in which raw data of EMM patients were available, were reviewed and summarized. Two trials conducted in our clinical centers were analyzed and presented with detailed data. Results According to published anti-BCMA CAR-T clinical trials, the ORR of EMM ranged from 57% to 100%, with the complete remission (CR) rate of 29% to 60%. Between February 22, 2017, and September 26, 2019, a total of 61 subjects (EMM 25; non-EMM 36) received anti-BCMA CAR-T cell infusion. The data-cutoff date was April 1, 2021. There were no statistical differences between EMM and non-EMM groups in adverse events (AEs), including cytokine release syndrome (CRS). The most common AEs of grade ≥ 3 in both groups were hematologic toxicities. There was no significant difference in the objective response rate (ORR) and ≥ complete remission (CR) rate between both groups. However, the ≥ CR rate of the EMM group was lower than the non-EMM group receiving the fully human anti-BCMA CAR-T cell therapy (p = 0.026). The median progression-free survival (PFS) for EMM and the non-EMM group was 121 days and 361 days, respectively (p = 0.001). The median overall survival (OS) for EMM and the non-EMM group was 248 days and 1024 days, respectively (p = 0.005). The Cmax and AUC0-28d for EMM group were lower than non-EMM group (Cmax, p = 0.016; AUC0-28d, p = 0.016). Extramedullary disease was an independent prognostic risk factor for PFS (hazard ratio, 2.576; 95% CI, 1.343 to 4.941; p = 0.004) and OS (hazard ratio, 2.312; 95% CI, 1.165 to 4.592; p = 0.017) in RRMM patients receiving anti-BCMA CAR-T cell therapy. Conclusions Based on our results, EMM patients could benefit from the two anti-BCMA CAR products, although they had a shorter PFS and OS compared with non-EMM patients.

Abstract
High-dose chemotherapy followed by autologous stem cell transplantation (HDT-ASCT) is the standard of care for chemosensitive relapsed or refractory (R/R) aggressive B cell lymphoma. Patients with a positive positron emission tomography (PET) scan before ASCT have a poor prognosis, and those who fail to achieve a therapeutic response better than partial remission after salvage treatment are ineligible candidates for ASCT. We conducted this open-label single-arm prospective clinical study to evaluate the safety and efficacy of sequential infusion of CD19/22 chimeric antigen receptor (CAR) T cells following HDT-ASCT. Eligibility for this study included patients with R/R aggressive B cell non-Hodgkin lymphoma (B-NHL) with 18F-fluorodeoxyglucose-PET positivity and patients with stable or progressive disease after salvage chemotherapy. Between November 14, 2016, and August 15, 2019, 42 patients underwent HDT-ASCT followed by CD19/22 CAR T cell infusion. Grade 3 cytokine release syndrome (CRS) occurred in only 2 patients. Twenty-one percent of patients experienced any grade of neurotoxicity, 5% with severe grade 3. All cases of CRS and neurotoxicity were reversible. The overall response rate was 90.5% (95% confidence interval [CI], 77.4% to 97.3%). At a median follow-up of 24.3 months, the median progression-free survival (PFS) and overall survival were not reached. The 2-year PFS rate was 83.3 % (95% CI, 68.2% to 91.7%). No patients were found to be CD19- and CD22-negative at the time of progression; 97.1% and 68.6% of patients with ongoing complete remission (CR) had consistently detectable levels of CD19 and CD22 CAR transgene, respectively, at 3 months. The median time to onset of sustained B cell recovery was 8.2 months. The high durable CR rates and favorable safety profiles support the strong potential of the HDT-ASCT plus CD19/CD22 CAR T cell cocktail therapy for the suboptimal group of patients with R/R aggressive B-NHL who are less sensitive or fail salvage chemotherapy. These early data are encouraging and informative for future trials to further test the efficacy and safety of HDT-ASCT plus CAR T cell therapy in a larger population. © 2021 American Society for Transplantation and Cellular Therapy.

Detection and Quantification of Chimeric Antigen Receptor Transgene Copy Number by Droplet Digital PCR versus Real-Time PCR. J Mol Diagn 2021; 22:699-707. [PMID: 32409121 DOI: 10.1016/j.jmoldx.2020.02.007] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Revised: 02/01/2020] [Accepted: 02/10/2020] [Indexed: 12/30/2022] Open
Abstract
Chimeric antigen receptor (CAR) T-cell immunotherapy is a new strategy for the treatment of refractory B-cell malignancies; therefore, the rapid and accurate quantification of CAR transgene copy number is essential. Real-time PCR was used for quantifying the copy number of chimeric antigen receptor transgene. Droplet digital PCR (ddPCR) is an absolute quantification method that does not require a standard curve. In this study, key performance parameters of the ddPCR and real-time PCR methods were assessed, including linearity, detection range, the lower limit of detection, repeatability, reproducibility, and accuracy, using a series of gradient diluted standards and clinical peripheral blood samples from CAR T-cell patients. The two platforms showed a good correlation for the standards (Pearson R2 = 0.9966; P < 0.0001) and clinical samples (Pearson R2 = 0.8952; P < 0.0001), and both showed good linearity (R2 = 0.9996 for ddPCR; R2 = 0.9984 for real-time PCR) over the detection range. Compared with real-time PCR, ddPCR showed lower intra-assay and interassay CVs for the series of diluted standards, which indicated ddPCR has better repeatability and reproducibility. The limit of detection of ddPCR was lower compared with that of real-time PCR. The combined results suggest that ddPCR is a more promising tool for the detection and quantification of the chimeric antigen receptor transgene copy number.

Abstract
Chimeric antigen receptor T (CAR T) cell immunotherapy has shown remarkable efficacy in non-Hodgkin’s lymphoma (NHL) patients. Minimal residual disease (MRD) monitoring in NHL is essential after CAR T cell therapy, which can be achieved by monitoring circulating tumor DNA (ctDNA). The mutation of TP53 in NHL has been suggested to be associated with a poor prognosis. However, whether TP53-mutated ctDNA can be used as a biomarker remains undetermined. In this study, a total of 40 patients with mutated TP53 who received CAR T cell treatment were analyzed, and specific probes targeting 29 different TP53 mutation sites in the 40 patients were designed and verified. Then, the presence of TP53-mutated ctDNA in longitudinal plasma samples was tracked by droplet digital PCR. Patients were stratified into two groups, favorable or unfavorable, based on their highest ctDNA level using a MAF cutoff of 3.15% according to the ROC curve. The unfavorable group had significantly worse PFS than the favorable group (p < 0.001). Our results suggest that patients with mutated TP53 with a favorable ctDNA profile in the first trimester have better prognostic outcomes than patients with an unfavorable profile, and ctDNA can be a reliable predictor of the subsequent clinical outcome.

Abstract
The application of silica nanoparticles (SiNPs) in areas of agriculture and medicine has raised great concerns for the potential adverse effects of SiNPs. The increasing toxicological studies focused mainly on the lung and cardiovascular system, but the adverse effects of SiNPs on nervous system have not been well explored. This study aimed to evaluate the role and mechanism of unfolded protein reaction (UPR) in SiNPs-induced cell injury on nerve cells in vitro. We investigated the UPR-mediated apoptosis caused by SiNPs in human neuroblastoma (SH-SY5Y) cell line. The size of SiNPs and its effect on cell ultrastructure were observed by transmission electron microscopy (TEM). Cell growth, mitochondrial membrane potential (MMP), calcium ion (Ca2+ ), apoptosis rate, and the expression level of related proteins were evaluated using MTT, flow cytometry, and western blot in SH-SY5Y cells exposed to SiNPs. The results showed that with the increase of SiNPs concentration, cell viability decreased, MMP decreased, active oxygen (ROS), and Ca2+ levels increased in a dose-dependent manner. In addition, protein expression of PERK, GRP78, and other related proteins in the unfolded protein response increased in a dose-response manner together with the expression of apoptosis proteins. Conclusively, this study confirmed that SiNPs can affect the neural system by interfering structure and functional and inducing apoptosis in nerve cells through unfolded protein response.

Abstract
BACKGROUND: Type 2 diabetes mellitus (T2DM) is a complex disease with high incidence and serious harm associated with polygenic determination. This study aimed to develop a predictive model so as to assess the risk of T2DM and apply it to health care and disease prevention in northern China. OBJECTIVE: Based on genotyping results, a risk warning model for type 2 diabetes was established. METHODS: Blood samples of 1042 patients with T2DM in northern China were collected. Multiplex polymerase chain reaction and high-throughput sequencing (NGS) techniques were used to design the amplification-based targeted sequencing panel to sequence the 21 T2DM susceptibility genes. RESULT: The related key gene KQT-like subfamily member 1 played an important role in the T2DM risk model, and single-nucleotide polymorphism rs2237892 was highly significant, with a P value of 1.2 × 10-5. CONCLUSIONS: Susceptibility genes in different populations were examined, and a model was developed to assess the risk-based genetic analysis. The performance of the model reached 92.8%.

Abstract
BACKGROUND Li-Fraumeni syndrome (LFS) is characterized as an autosomal dominant cancer predisposition disorder caused by germline TP53 gene mutations. Both primary and therapy-related hematopoietic malignancies with LFS are associated with dismal outcomes with standard therapies and even allogenic stem cell transplantation (SCT). CASE PRESENTATION We reported a relapsed/refractory acute B-cell lymphoblastic lymphoma (B-LBL) patient in the context of LFS. He was identified to harbor a TP53 c.818G>A (p.R273H) germline mutation, and his family history was significant for rectal carcinoma in his father, an unknown cancer in his sister and acute lymphoblastic leukemia in his brother and one of his sons. The patient received murine monoclonal anti-CD19 and anti-CD22 chimeric antigen receptor (CAR) T-cell "cocktail" therapy and achieved complete remission with negative minimal residual disease (MRD), as assessed by morphology and multiparameter flow cytometry. Fifteen months after murine monoclonal CAR T-cell "cocktail" therapy, the patient's B-LBL recurred. Fortunately, a round of fully human monoclonal anti-CD22 CAR T-cell therapy was still effective in this patient, and he achieved CR again and continued to be followed. Each time after infusion, the CAR T-cells underwent extremely rapid exponential expansion, which may be due to the disruption of TP53, a gene that can functionally control cell cycle arrest. Grade 4 and grade 1 cytokine release syndrome occurred after the first and second rounds of CAR T-cell therapy, respectively. CONCLUSIONS This case provides the first report of the use of CAR T-cell therapy in a hematologic malignancy patient with LFS. As traditional chemotherapy and allogenic SCT are not effective therapy strategies for patients with hematologic malignancies and LFS, CAR T-cell therapy may be an alternate choice.ChiCTR-OPN-16008526 and ChiCTR1900023922.

Abstract
BACKGROUND Relapsed/refractory (R/R) multiple myeloma (MM) patients and primary plasma cell leukemia (PCL) have an unfavorable prognosis and no effective treatment. This study was designed to assess the safety and preliminary efficacy of a novel anti-B-cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T cell in R/R MM and PCL. METHODS Between February 22, 2017, and June 25, 2018, 28 R/R and two R/R primary PCL patients received a median dose of 11.2 × 106 CAR+ cells/kg. The subjects were refractory to a proteasome inhibitor and/or an immunomodulatory agent. Fludarabine and cyclophosphamide were given as lymphodepletion chemotherapy. RESULTS Results for these 30 consecutive patients who received an anti-BCMA CAR T cell infusion are reported. The patients had received a median of four prior lines of therapy. A total of 44 different types of adverse events were recorded, and hematologic toxic effects were the most common events of any grade during treatment. Hematologic toxic effects were also the most common events of grade 3 or higher. A total of 29 patients (96.7%) had cytokine release syndrome, which was of grade 1 or 2 in 24 patients (80%) and grade 3 in five patients (16.7%). Neurologic toxic effects only occurred in one patient (3.3%) and were of grade 1. The objective response rate was 90%, and the complete response rate was 43.3%. With a median follow-up of 12.6 months, the median progression-free survival (PFS) and overall survival were 5.2 months and 14.0 months. One of the two primary PCL achieved a complete response with a PFS of 307 days. The other patients achieved a very good partial response with a PFS of 117 days. CONCLUSIONS Anti-BCMA CAR T cell treatment is safe and highly active in R/R multiple myeloma.

Abstract
BACKGROUND Immune and inflammatory dysfunction was reported to underpin critical COVID-19(coronavirus disease 2019). We aim to develop a machine learning model that enables accurate prediction of critical COVID-19 using immune-inflammatory features at admission. METHODS We retrospectively collected 2076 consecutive COVID-19 patients with definite outcomes (discharge or death) between January 27, 2020 and March 30, 2020 from two hospitals in China. Critical illness was defined as admission to intensive care unit, receiving invasive ventilation, or death. Least Absolute Shrinkage and Selection Operator (LASSO) was applied for feature selection. Five machine learning algorithms, including Logistic Regression (LR), Support Vector Machine (SVM), Gradient Boosted Decision Tree (GBDT), K-Nearest Neighbor (KNN), and Neural Network (NN) were built in a training dataset, and assessed in an internal validation dataset and an external validation dataset. RESULTS Six features (procalcitonin, [T + B + NK cell] count, interleukin 6, C reactive protein, interleukin 2 receptor, T-helper lymphocyte/T-suppressor lymphocyte) were finally used for model development. Five models displayed varying but all promising predictive performance. Notably, the ensemble model, SPMCIIP (severity prediction model for COVID-19 by immune-inflammatory parameters), derived from three contributive algorithms (SVM, GBDT, and NN) achieved the best performance with an area under the curve (AUC) of 0.991 (95% confidence interval [CI] 0.979-1.000) in internal validation cohort and 0.999 (95% CI 0.998-1.000) in external validation cohort to identify patients with critical COVID-19. SPMCIIP could accurately and expeditiously predict the occurrence of critical COVID-19 approximately 20 days in advance. CONCLUSIONS The developed online prediction model SPMCIIP is hopeful to facilitate intensive monitoring and early intervention of high risk of critical illness in COVID-19 patients.

Abstract
Patients with malignancy were reportedly more susceptible and vulnerable to Coronavirus Disease 2019 (COVID-19), and witnessed a greater mortality risk in COVID-19 infection than noncancerous patients. But the role of immune dysregulation of malignant patients on poor prognosis of COVID-19 has remained insufficiently investigated. Here we conducted a retrospective cohort study that included 2,052 patients hospitalized with COVID-19 (Cancer, n = 93; Non-cancer, n = 1,959), and compared the immunological characteristics of both cohorts. We used stratification analysis, multivariate regressions, and propensity-score matching to evaluate the effect of immunological indices. In result, COVID-19 patients with cancer had ongoing and significantly elevated inflammatory factors and cytokines (high-sensitivity C-reactive protein, procalcitonin, interleukin (IL)-2 receptor, IL-6, IL-8), as well as decreased immune cells (CD8 + T cells, CD4 + T cells, B cells, NK cells, Th and Ts cells) than those without cancer. The mortality rate was significantly higher in cancer cohort (24.7%) than non-cancer cohort (10.8%). By stratification analysis, COVID-19 patients with immune dysregulation had poorer prognosis than those with the relatively normal immune system both in cancer and non-cancer cohort. By logistic regression, Cox regression, and propensity-score matching, we found that prior to adjustment for immunological indices, cancer history was associated with an increased mortality risk of COVID-19 (p < .05); after adjustment for immunological indices, cancer history was no longer an independent risk factor for poor prognosis of COVID-19 (p > .30). In conclusion, COVID-19 patients with cancer had more severely dysregulated immune responses than noncancerous patients, which might account for their poorer prognosis. Clinical Trial: This study has been registered on the Chinese Clinical Trial Registry (No. ChiCTR2000032161).

Abstract
Objective: To investigate the clinical value of holographic multimodal real-time three-dimensional navigation (3D-HMRN) technology for navigation and localization of pulmonary micro lesions. Methods: A total of 152 patients who underwent thoracoscopic partial resection of small pulmonary nodules in the Department of Thoracic Surgery of the First Medical Center of Chinese PLA General Hospital from June 2017 to December 2019 were retrospectively collected and were divided into two groups by computer random number. The experimental group consists of 76 patients (31 males and 45 females) with a mean age of (47±17) years. CT scan in lateral position navigation mode and 3D reconstruction of the surgical area were performed on all patients. Before the operation, holographic multimodal real-time 3D navigation technology was used to guide the puncture of the lesion. After the operation was completed, the intraoperative CT was used to verify the location of the puncture and determine the accuracy and error rang of the puncture. The control group consists of 76 patients (34 males and 42 females) with a mean age of (50±19) years. Intraoperative CT positioning was directly subjected to the patients. And then, the localization data of the two groups were compared and statistically analyzed. Results: Seventy-six cases of positioning puncture using navigation technology, the first success rate was 97.4%, the error was (3.9±0.9) mm, and the average operation time was (4.4±1.2) min; while the success rate of one-time CT positioning during routine surgery was 98.7%, the error was (3.5±1.0) mm, and the average operating time was (10.7±2.6) min. Compared with intraoperative CT positioning, the success rate and positioning accuracy of 3D-HMRN were not statistically significant (both P>0.05), however the operation time was significantly shortened (P<0.01). Conclusion: The holographic multi-modal real-time 3D navigation technology saves time and has accurate positioning, which may be used as an effective method for localization of pulmonary micro nodules during surgical treatment.

Abstract
BACKGROUND The ferocious global assault of COVID-19 continues. Critically ill patients witnessed significantly higher mortality than severe and moderate ones. Herein, we aim to comprehensively delineate clinical features of COVID-19 and explore risk factors of developing critical disease. METHODS This is a Mini-national multicenter, retrospective, cohort study involving 2,387 consecutive COVID-19 inpatients that underwent discharge or death between January 27 and March 21, 2020. After quality control, 2,044 COVID-19 inpatients were enrolled. Electronic medical records were collected to identify the risk factors of developing critical COVID-19. FINDINGS The severity of COVID-19 climbed up straightly with age. Critical group was characterized by higher proportion of dyspnea, systemic organ damage, and long-lasting inflammatory storm. All-cause mortality of critical group was 85•45%, by contrast with 0•58% for severe group and 0•18% for moderate group. Logistic regression revealed that sex was an effect modifier for hypertension and coronary heart disease (CHD), where hypertension and CHD were risk factors solely in males. Multivariable regression showed increasing odds of critical illness associated with hypertension, CHD, tumor, and age ≥ 60 years for male, and chronic obstructive pulmonary disease (COPD), chronic kidney disease (CKD), tumor, and age ≥ 60 years for female. INTERPRETATION We provide comprehensive front-line information about different severity of COVID-19 and insights into different risk factors associated with critical COVID-19 between sexes. These results highlight the significance of dividing risk factors between sexes in clinical and epidemiologic works of COVID-19, and perhaps other coronavirus appearing in future.

Abstract
Objective: To investigate the difference of serum glutamate (Glu) and gamma- aminobutyric acid (GABA) levels between depressive patients and bipolar disorder patients with depressive episodes. Methods: From May 2018 to March 2019, forty-seven patients with depression (depression group) and 45 patients with bipolar depressive episode (bipolar depression group) were selected from the department of psychiatry, the First Affiliated Hospital of Jinan University, and 41 healthy controls (healthy control group) were simultaneously recruited from the community. The subjects' depression and anxiety were assessed by 17 items of Hamilton depression scale (HAMD-17) and Hamilton Anxiety Scale (HAMA). The serum levels of Glu, GABA and Glu decarboxylase (GAD) were detected by enzyme-linked immunosorbent assay (ELISA) . Results: The serum Glu level ( (36±7) mg/L, (37±7) mg/L vs (28±4) mg/L, F=10.97, P<0.01) and Glu/GABA ratio (5.77±0.35, 8.18±0.24 vs 3.35±0.33, F=37.68, P<0.01) in depression and bipolar depression groups were higher than those of healthy control group, while the GABA level ((6.1±0.7) μmol/L,(4.1±0.8) μmol/L vs (8.1±1.2) μmol/L, F=21.61, P<0.01) and GAD ((31±6) U/L, (31±6) U/L vs (35±6) U/L, F=5.61, P<0.01) were lower than those of healthy control group. The level of serum GABA in bipolar depression group was lower than that in depression group. However, Glu/GABA was higher in bipolar depression group than that in depression group (P<0.01). The level of serum GABA in depression group was negatively correlated with HAMD sleep disorder factor (r=-0.46, P=0.01). Conclusions: Both depression and bipolar depression have abnormal levels of Glu, GABA neurotransmitters and imbalance between Glu and GABA in peripheral blood circulation. Moreover, these abnormalities are more obvious in patients with bipolar depression.

Abstract
The low-temperature electrical transport properties of the rare-earth (RE) Ce, Dy, Sm element doped Fe2VAl Heusler alloys have been investigated. A significant enhancement in the Seebeck coefficientS(peak values of about -125 to -160μV K-1) is observed as compared to the pure Fe2VAl (peak value of about 40μV K-1). It is observed that the thermal conductivity reduced by 50% in RE-doped samples. The single parabolic band model has been used to analyze the experimental data and to understand the role of fundamental parameters like the Lorenz number. The lattice contribution to the total thermal conductivity was analyzed through the Callaway model, which in turn provided the insight into the phonon scattering in these alloys. Finally, we demonstrate a significant improvement in power factor and figure of merit at all temperatures for the RE-doped Fe2VAl alloys.

Abstract
BACKGROUND Postoperative depression is one of the most common mental disorders in patients undergoing cancer surgery and it often delays postoperative recovery. We investigated whether dezocine, an analgesic with inhibitory effect on the serotonin and norepinephrine reuptake, could relieve postoperative depressive symptoms in patients undergoing colorectal cancer surgery. METHODS This randomized, controlled, single-center, double-blind trial was performed in the Second Affiliated Hospital of the Army Medical University. A total of 120 patients were randomly assigned to receive either sufentanil (1.3 μg/kg) with dezocine (1 mg/kg) (dezocine group; n = 60) or only sufentanil (2.3 μg/kg) (control group; n = 60) for patient-controlled intravenous analgesia after colorectal cancer surgery. The primary outcome was the Beck Depression Inventory score at 2 days after surgery. The secondary outcomes included the Beck Anxiety Inventory, sleep quality, and quality of recovery scores. RESULTS Compared with those in the control group, patients in the dezocine group had lower depression scores (7.3±3.4 vs. 9.9±3.5, mean difference 2.6, 95% CI: 1.4-3.9; P<0.001) at 2 days after surgery and better night sleep quality at the day of surgery (P = 0.010) and at 1 day after the surgery (P<0.001). No significant difference was found in other outcomes between the two groups. CONCLUSIONS Intravenous analgesia using dezocine can relieve postoperative depression symptoms and improve sleep quality in patients undergoing colorectal cancer surgery.

Abstract
Temperature regulations (mesophilic/thermophilic) and digesting modes (mono-/co-digestion) play key roles in the biomethane potential of anaerobic digestion, but limited research focus on the synergetic effects on microbial interconnections of the biomethane process. In this study, the pineapple and maize residues under different operations were monitored by batch biogas assays and 16S high-throughput sequencing to explore: 1) biomethane potential regarding different operations, 2) microbial communities in different treated reactors, and 3) significant factors determine microbial distribution. Results showed that the co-digestion had higher methanogenic abundance and biomethane production (~3300 mLn) versus mono-digestion under mesophilic condition. To the thermophilic condition, the co-digestion had less methanogenic abundance but more biomethane production (~5000 mLn). Statistical evidence uncovered that the Clostridiaceae and Thermoanaerobacteraceae dominated pathways linked closely with methanogenesis which may contribute the more biomethane production in the thermophilic condition. This study demonstrated the temperature regulations drove rare taxa as major contributors for biomethane production.
