Abstract
Objective: To investigate the value of net water uptake (NWU) for predicting early neurological improvement (ENI) after endovascular treatment in patients with acute anterior circulation large vessel occlusion stroke. Methods: A case-control study. A total of 132 patients (80 men, 52 women, median age 68 years) with acute anterior circulation large vessel occlusive stroke receiving endovascular treatment were retrospectively analyzed at Jinling Hospital from October 2014 to September 2019. Patients were divided into two groups based on the occurrence of ENI, which was defined as either an improvement of NIHSS score of ≥4 points, or an NIHSS score of 0 or 1 at 24 hours after endovascular treatment. The rank sum test, Chi square test, and other methods were used to compare differences in baseline characteristics between the two groups. Logistic regression analysis was used to investigate independent predictors of postoperative ENI. Receiver operating characteristic curve analysis used to assess the capacity of NWU to predict ENI. Results: Of the 132 patients in the study, ENI occurred in 47 and did not occur in 85. In multivariate logistic regression analysis age [odds ratio (OR)=0.940, 95% confidence interval (CI) 0.903-0.979, P=0.003], time from stroke onset to puncture (OR=0.995, 95%CI 0.991-0.999, P=0.025), time from puncture to recanalization/end of operation (OR=0.985, 95%CI 0.974-0.996, P=0.007), NWU (OR=0.762, 95%CI 0.620-0.937, P=0.010), and mTICI (OR=1.644, 95%CI 1.043-2.590, P=0.032) were predictive factors for ENI. Receiver operating characteristic curve analysis indicated that NWU could effectively predict ENI (area under the curve=0.642, 95%CI 0.543-0.741, P=0.007), and prediction accuracy was improved when it was combined with other clinical parameters. Conclusion: NWU is an independent predictor of ENI in patients with acute anterior circulation large vessel occlusive stroke undergoing endovascular treatment.

Abstract
BACKGROUND In adults undergoing noncardiac surgery, the correlation between intraoperative tidal volume and postoperative acute kidney injury (AKI) is unclear. This study aimed to investigate the effects of low tidal volume ventilation on the incidence of postoperative AKI compared with conventional tidal volume in adults undergoing noncardiac surgery. METHODS This was a two-center prospective randomized controlled trial on adult patients who underwent noncardiac surgery and had a mechanical ventilation of >60 min. Patients were randomized to receive either a tidal volume of 6 mL/kg pre-predicted body weight (PBW, low tidal volume) or a tidal volume of 10 mL/kg pre-predicted body weight (conventional tidal volume). The primary outcome was the incidence of AKI after non-cardiac surgery. Appropriate statistical methods were used for this study. RESULTS Among the 1982 randomized patients, 943 with low tidal volume and 958 with conventional tidal volume were evaluable for the primary outcome. Postoperative AKI occurred in 12 patients (1.3%) in the low tidal volume group and 11 patients (1.1%) in the conventional tidal volume group, with an odds ratio of 0.889 (95%CI, 0.391-2.03) and a relative risk of 0.999 ([95%CI, 0.989-1.01]; P=0.804). Postoperative serum creatinine levels increased in 284 (30.0%) patients with low tidal volume compared to 316 (32.0%) patients with conventional tidal volume (P=0.251). No difference in postoperative serum creatinine levels was found between the two groups (57.5 [49.0-68.2] μmol/L vs. 58.8[50.4-69.5] μmol/L, P=0.056). CONCLUSIONS Among adults undergoing noncardiac surgery, low tidal volume mechanical ventilation did not significantly reduce the incidence of postoperative AKI compared with conventional tidal volume.

Abstract
Neuropathic pain has a complex pathogenesis. Here, we examined the role of caveolin-1 (Cav-1) in the anterior cingulate cortex (ACC) in a chronic constriction injury (CCI) mouse model for the enhancement of presynaptic glutamate release in chronic neuropathic pain. Cav-1 was localized in glutamatergic neurons and showed higher expression in the ACC of CCI versus sham mice. Moreover, the release of glutamate from the ACC of the CCI mice was greater than that of the sham mice. Inhibition of Cav-1 by siRNAs greatly reduced the release of glutamate of ACC, while its overexpression (induced by injecting Lenti-Cav-1) reversed this process. The chemogenetics method was then used to activate or inhibit glutamatergic neurons in the ACC area. After 21 days of injection of AAV-hM3Dq in the sham mice, the release of glutamate was increased, the paw withdrawal latency was shortened, and expression of Cav-1 in the ACC was upregulated after intraperitoneal injection of 2 mg/kg clozapine N-oxide. Injection of AAV-hM4Di in the ACC of CCI mice led to the opposite effects. Furthermore, decreasing Cav-1 in the ACC in sham mice injected with rAAV-hM3DGq did not increase glutamate release. These findings suggest that Cav-1 in the ACC is essential for enhancing glutamate release in neuropathic pain.

Abstract
Objective: To investigate the value of stool-based methylated SDC2 test in physical examination population for the screening of colorectal neoplasms. Methods: Using the prospective cohort study method, from December 2020 to November 2021, 2 107 participants from the First People's Hospital of Xiushui County, Jiangxi Province were enrolled, consisted of 1 012 males and 1 094 females, aged 20-90 years with the median age of 49 years old. Fresh stool samples were collected and SDC2 DNA methylation tests were carried out as the primary screening method. The participants with positive results were recommended to undergo colonoscopy, and those who were negative were followed up by telephone. The positive rate of screening, the compliance of colonoscopy, and the detection of colorectal lesions were analyzed by chi-square test. Combined the follow-up results of negative subjects, the value of SDC2 DNA methylation test for the screening of colorectal neoplasms was evaluated. Results: Among the 2 107 participants, 2 106 completed the SDC2 methylation test. 113 participants (5.4%) were positive. The positive rate of primary screening increased with age significantly (χ2=32.135, P<0.001). Out of 113 cases, 72 (63.7%) underwent colonoscopy examinations. Finally, 3 (4.2%) cases of colorectal cancer, 12 (16.7%) cases of advanced adenoma, 31 (43.1%) cases of non-advanced adenoma, and 16 (22.2%) cases of non-adenomatous polyp were detected. The positive predictive value (PPV) of stool-based SDC2 DNA methylation test for intestinal lesions and colorectal neoplasms were 86.1% and 63.9%, respectively. Among the 1 374 follow-up participants, the negative predictive value (NPV) of this test for intestinal lesions and colorectal neoplasms were 97.7% and 99.4%, respectively. Conclusion: Primary stool-based SDC2 DNA methylation test and subsequent colonoscopy examination can effectively find colorectal neoplasms. This strategy may be a potential tool for the screening of colorectal neoplasms in general risk population.

Abstract
Objective: To investigate the frequency of neurotrophic tyrosine receptor kinase (NTRK) gene variations in papillary thyroid carcinoma (PTC) and to analyze the feasibility of detecting tropomyosin receptor kinase (TRK) proteins using immunohistochemistry (IHC) to predict the fusion variation of NTRK. Methods: A cohort of 848 PTC cases was collected at the Department of Pathology, Shenzhen People's Hospital from June 2017 to June 2020. The expression levels of TRK proteins were detected using IHC in 848 PTC samples, and the DNA-based next generation sequencing (NGS) was performed to detect NTRK rearrangements in 150 PTCs. Results: There were 242 males and 606 females, with an age range of 9-83 years. In 120 cases with TRK expression detected by IHC, 13 cases were confirmed to harbor a NTRK gene fusion by NGS. The frequency of NTRK fusion in PTC was 1.5% (13/848). The sensitivity and specificity of TRK-IHC positivity for screening NTRK fusion in PTC were 100% and 21.9%, respectively. The specificity of weak-, moderate- and strong-positive stains of TRK IHC were 23.8%, 76.9% and 93.8%, respectively. The specificity of NTRK gene fusion was predicted to increase with the enhanced intensity of IHC staining. In BRAF V600E negative PTC samples, the specificity of weak-and moderate-positive stains of TRK IHC increased to 62.5% and 96.8%, respectively. Seven NTRK fusion partners were found in the PTC, including EML4, ETV6, CDH1, GJD2, TPR, TFG and SQSTM1. Conclusions: There is a low variation frequency of NTRK gene fusion in PTC. TRK IHC can be used as a screening method for NTRK fusion variation in PTC. The specificity of TRK IHC predicting NTRK fusion can be further enhanced by increasing the cutoff value of the positive cell number and staining intensity of TRK-IHC staining, or being combined with BRAF V600E negativity.

Abstract
Objective: To analyze the changes in self-efficacy and its influencing factors in type 2 diabetic patients after community-based self-management group intervention. Methods: From August to November 2014, a 3-month community-based self-management intervention study of type 2 diabetes patients was implemented in Fangshan District, Beijing. 510 patients were recruited through posters, household inquiries and telephone notification and then were randomly divided into intervention group (260 patients) and control group (250 patients). Finally, 500 patients completed the study, including 259 in the intervention group and 241 in the control group. Self-efficacy score was measured through face-to-face interview at different time points, including pre-intervention, post-intervention, 2 years after the intervention and 5 years after the intervention, respectively. A two-level random coefficient model was fitted to analyze the long-term trend of self-efficacy and its relationship with group intervention. Results: Individual-level educational attainment, disease duration as well as their treatment plans had a positive correlation with self-efficacy of type 2 diabetic patients while gender and age did not affect their self-efficacy. Patients with junior middle school education, senior high school education and university and above education had 4.66 (P<0.05), 6.40 (P<0.05) and 11.02 (P<0.05) points higher than those with primary education, respectively. The self-efficacy of diabetic patients increased by 0.23 (P<0.05) for each additional course year. The effect of treatment plan on self-efficacy was mainly reflected in the self-efficacy of taking medication or insulin injection as prescribed and blood glucose monitoring. After controlling for the confounding factors, i.e., gender, age, disease duration, educational attainment, and treatment plan, self-efficacy scores at the post-intervention increased in both groups compared to those at the pre-intervention. The intervention group had 7.95 points higher than the control group (P<0.05). After the intervention, the self-efficacy scores of both groups decreased year by year while the intervention group declined faster, with 5.41 points (P<0.05) at 2 years after the intervention and 8.94 points (P<0.05) at 5 years after the intervention. Conclusion: Community-based self-management group intervention could improve the self-efficacy of type 2 diabetic patients while the self-efficacy decreases year by year in the absence of follow-up intervention.

Abstract
Schizophrenia is a severe psychiatric disorder with high premature mortality rates. This is a meta-analysis and systematic review of the prevalence of suicidal ideation (SI) and suicide plan (SP) among people with schizophrenia. PubMed, Web of Science, Embase, and PsycINFO were systematically searched from their respective inception to October 10, 2020. Data on prevalence of SI and/or SP were synthesized using the random effects model. Twenty-six studies covering 5079 people with schizophrenia were included for meta-analysis. The lifetime and point prevalence of SI were 34.5% (95% CI: 28.2-40.9%), and 29.9% (95% CI: 24.2-35.6%), respectively. The lifetime prevalence of SP was 44.3% and the point prevalence of SP ranged between 6.4 and 13%. Subgroup and meta-regression analyses revealed that source of patients, survey countries, and sample size were significantly associated with the point prevalence of SI, while male proportion and quality assessment scores were significantly associated with the lifetime and point prevalence of SI. Survey time and mean age were significantly associated with lifetime prevalence of SI. Both SI and SP are common in people living with schizophrenia, especially in males and inpatients. Routine screening and effective interventions for SI and SP should be implemented in this population.

Abstract
Anti-CD19 chimeric antigen receptor (CAR) T-cell therapy has led to unprecedented results to date in relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL), yet its clinical application in elderly patients with R/R DLBCL remains somewhat limited. In this study, a total of 31 R/R DLBCL patients older than 65 years of age were enrolled and received humanized anti-CD19 CAR T-cell therapy. Patients were stratified into a fit, unfit, or frail group according to the comprehensive geriatric assessment (CGA). The fit group had a higher objective response (OR) rate (ORR) and complete response (CR) rate than that of the unfit/frail group, but there was no difference in the part response (PR) rate between the groups. The unfit/frail group was more likely to experience AEs than the fit group. The peak proportion of anti-CD19 CAR T-cells in the fit group was significantly higher than that of the unfit/frail group. The CGA can be used to effectively predict the treatment response, adverse events, and long-term survival.

Abstract
Objective: To compare the activity difference of the high affinity humanized CD19 chimeric antigen receptor (CAR)-T cells and murine CD19 CAR-T cells. Methods: Peripheral venous blood T cells from 8 healthy volunteers were collected and infected with humanized and murine CD19 CAR lentivirus. Human and murine CD19 CAR-T cells were prepared and cell proliferation was detected by cell counting kit-8 (CCK-8) method. The cytotoxicity of CD3(+) T cells, humanized and murine CD19 CAR-T cells to NALM-6 cells was detected by lactate dehydrogenase assay. Thirty BAL B/c nude mice transplanted with NALM-6 cells were randomly divided into 3 groups with 10 mice in each group and injected humanized CD19 CAR-T cells, mouse CD19 CAR-T cells and control CD3(+) T cell via tail vein, respectively. The proportion of NALM-6 cells in peripheral blood and the proportion of CD19 CAR-T cells in T cells from the vein of the inner canthus were detected by flow cytometry. The overall survival of BAL B/c nude mice was observed. Results: The proliferation of mouse and humanized CD19 CAR-T cells were (68.50±0.93)% and (80.63±1.41)%, respectively (t=20.353, P<0.001) after cultured in vitro for 24 hours, and were (91.38±1.41)% and (148.13±1.25)%, respectively (t=85.364, P<0.001) after cultured for 48 hours. When the effect to target ratio was 1∶1, there was no difference between the humanized and murine CD19 CAR-T cell group after co-culture for 24 hours (P=0.169), while the killing activity of humanized CD19 CAR-T cells against NALM-6 cells was higher than that of murine CD19 CAR-T cells (P<0.01) after 48 hours of co-culture. When the effect to target ratio was 4∶1, the cytotoxicity of humanized CD19 CAR-T cells against NALM-6 cells was higher than that of murine CD19 CAR-T cells in co-culture for 24 and 48 hours (P<0.01). On the seventh day of CD19 CAR-T cell therapy, the proportion of NALM-6 cells in the peripheral blood of BAL B/c nude mice decreased to the lowest level in the humanized CD19 CAR-T cell group and the murine CD19 CAR-T cell group. After 21 days, the proportion of NALM-6 cells in the murine CD19 CAR-T cell group was higher than that in the humanized CD19 CAR-T cell group (P(21 d)=0.001, P(28 d)<0.001, P(35 d)<0.001). The proportion of humanized and murine CD19 CAR-T cells in the peripheral blood reached the peaks after 7 days of therapy, and the proportion of humanized CD19 CAR-T cells was higher than that of murine CAR-T cells (P(7 d)=0.002). The CD19 CAR-T cells disappeared in the peripheral blood in the murine CD19 CAR-T cell group after 14 days of therapy, while in the humanized CD19 CAR-T cell group it disappeared after 21 days of therapy. The median survival of BAL B/c nude mice in the murine CD19 CAR-T cell group and the humanized CD19 CAR-T cell group was 42 days and 63 days, respectively (χ(2)=15.382, P<0.001). Conclusions: High affinity humanized CD19 CAR-T cells have stronger proliferation, higher cytotoxicity and longer survival time compared with those of murine CD19 CAR-T cells. The results indicate that the clinical efficacy of humanized CD19 CAR-T cells would be better than that of murine CD19 CAR-T cells.

Abstract
Objective: To observe the efficacy and safety of humanized anti-BCMA chimeric antigen receptor modified (BCMA CAR) -T cell therapy after disease progression with their murine BCMA CAR-T cell therapy in patients with relapsed/refractory multiple myeloma (MM) . Methods: Study participants underwent leukapheresis to collect T cells for BCMA CAR-T manufacturing. Patients were pretreated with intensive chemotherapy (fludarabine combined with cytarabine) before CAR-T therapy. Adverse events (AEs) , CAR DNA expansion, and cytokine were monitored. In vitro, transfection efficacy, specific cytotoxicity, and inflammatory response were detected when co-cultured with effector and target cells. Results: Patient (PT) 1 and 2 achieved complete remission (CR) and disease stability at 3 months post murine CAR-T therapy. However, 16 and 18 months later, they experienced progression of disease (PD) , and patient 1 presented with extramedullary disease at PD. Both of the patients received humanized CAR-T therapy and achieved partial remission (PR) and very good partial remission (VGPR) post humanized CAR-T therapy. PT1 achieved CR of the soft tissue masses at 4 months post humanized CAR-T therapy. Notably, the median peak of the BCMA CAR-T cells, copy of BCMA CAR gene, persistence of BCMA CAR-T, and the peak levels of IL-6, IL-8, IL-10, IFN-γ and TNF-α were higher in humanized CAR-T therapy than those in the murine CAR-T therapy. During the murine CAR-T therapy, both of the patients experienced grade 1 CRS and no ICANS. PT1 experienced grade 3 CRS and grade 2 ICANS during humanized CAR-T therapy, which were relieved by supportive care. Grade 2 CRS was observed for patient 2 during humanized CAR-T therapy. Humanized BCMA CAR-T cells showed a higher inflammatory response and in vitro cytotoxicity than that of murine BCMA CAR-T cells with effector/targets cells at 1∶1 over 48 hours (P<0.001) . The proportions of residual cells in humanized BCMA CAR-T and murine CAR-T were (17.38±5.18) % vs (28.27±4.58) %, (13.25±1.62) % vs (22.77±1.77) % for PT1 and PT2, respectively. Conclusions: The humanized BCMA CAR-T cell therapy was efficient and safe for patients who experienced progression of disease after the murine CAR-T therapy, especially for patients with extramedullary disease.

Abstract
Objective: To evaluate the quality of the National Demonstration Area for Comprehensive Prevention and Control of NCDs (referred to as "the Demonstration Area"). Methods: Based on the evaluation scores of the Demonstration Area field survey from 2017 to 2019, we counted the scores of each indicator, comparing the scores among indicators and regions. x±s was used to describe the scores. The 95%CI of the score was used to test the statistical difference among regions. Each score was converted into a hundred-mark system to compare the scores among indicators. Results: Of 236 Demonstration Areas, the total score was 83.5. The scores of the first-level indicator listed from high to low appeared as Integrating System of NCD Prevention and Control (92.8), Policy Perfection (90.3), Building Supportive Environment for NCD Prevention and Control (88.4), Implementation of Health Education and Health Promotion (87.4), Whole-course Management of NCDs (78.1), Innovation and Guidance (76.5), Surveillance and Evaluation (75.1). Total scores were higher in the east (259.2±18.8) comparing to the middle (243.2±15.2) or the west (245.4±19.7) regions. Conclusions: Substantial variations on the quality in the Demonstration Area existed across different regions in China. These disparities are important to the government when developing health policies and allocating resources. Whole-course Management of NCDs, Surveillance and Evaluation, and Innovation and Guidance in the Demonstration Area also needs to be improved.

Abstract
Objective: To investigate the characteristics and cytotoxicity in vitro of the residual leukemia cells in the culture system that caused the accidental transfer of CD19 chimeric antigen receptor (CAR) into leukemia cells during the preparation of autologous CD19 CAR-T cells of relapsed/refractory B-cell acute lymphoblastic leukemia. Methods: ①Peripheral blood mononuclear cells (PBMC) of 30 patients with relapsed/refractory B-cell acute lymphoblastic anemia (R/R B-ALL) who accepted CD19 CAR-T cell therapy and six healthy volunteers were collected. ②The residual leukemia cells were analyzed by flow cytometry in the system after the PBMCs of R/R B-ALL patients were sorted by CD3 magnetic beads. ③ CD3(+) T cells from patients and healthy volunteers were transfected with CD19 CAR and CD22 CAR lentivirus to prepare CD19 CAR-T and CD22 CAR-T cells. ④The Nalm-6 cell line was resuscitated and the Nalm-6 cells with CD19 CAR lentivirus were transfected to prepare CD19 CAR-Nalm-6 cells. The patient's primary ALL cells were transfected with CD19 CAR lentivirus at the same time. ⑤The transfection rates were analyzed by flow cytometer, the cell proliferation was analyzed by the CCK-8 method, and the cell-killing activities were detected by the lactate dehydrogenase method. Results: ① Among the 30 R/R B-ALL patients who received CD19 CAR-T cell therapy, two patients had 2.04% and 3.32% residual leukemia cells in CD3(+) T cells. After 4 days in culture, the residual leukemia cells disappeared and could not be detected by a flow cytometer with prolonged cultivation in vitro. ② The proliferation of CD19 CAR-Nalm-6 cells was higher than that of the Nalm-6 cells. ③ The killing activity of the CD19 CAR-T cells on Nalm-6 cells was higher than that of the CD19 CAR-Nalm6 cells at a target ratio of 1∶1 on 24, 48, 72 h, respectively. The cytotoxicity of CD22 CAR-T cells on CD19 CAR-Nalm-6 cells was significantly higher than that of CD19 CAR-T cells. ④ The cytotoxicity of CD22 CAR-T alone on CD19 CAR-Nalm-6 cells was higher than that of CD19 CAR-T combined with CD22 CAR-T at the same target ratio. Conclusion: The residual leukemia cells in the culture system in the preparation of CD19 CAR-T cells may lead to the introduction of CD19 CAR into leukemia cells and results in the failure of the CD19 CAR-T cell therapy. Detecting the residual leukemia cells in the culture system via flow cytometry before transfection with CD19 CAR lentivirus is needed. Thus, CD22 CAR-T cell therapy could be used as one of the salvage treatments.

Abstract
Objective: This study aimed to evaluate the maintenance therapy following an anti-CD19-CAR T-cell therapy for a B-cell acute lymphoblastic leukemia (ALL) patient who relapsed after allogeneic hematopoietic cell transplantation (allo-HSCT) and investigate the effect of donor stem cells and donor T lymphocyte infusion on the amplification of CD19 CAR-T cells. Methods: One refractory B-ALL patient relapsed after murine CD19 CAR-T cell therapy followed by a sibling allo-HSCT. He underwent a humanized CD19 CAR-T cell therapy followed by donor stem cell and donor T lymphocytes infusions as maintenance therapy in our hospital. The level of cytokines, the proportion of CD19 CAR-T cell, the level of CAR19 DNA expression in the peripheral blood, and the proportion of leukemia cells and donor chimerism in the bone marrow were detected. Correspondingly, T lymphocytes from the C57 spleen were separated to modify the CD19 CAR lentivirus and refused into C57 mice, and after 14 days, the B lymphocytes from C57 mice were separated and refused into the same C57 mice. The CD19 CAR T cells, B cells, and CD19 CAR gene counts in the peripheral blood were evaluated at different time points. Results: ①The patient achieved a complete response (CR) 14 days after a humanized CD19 CAR-T therapy with grade 1 cytokine release syndrome (CRS) and restored a donor chimerism to 99.76%. ② Following the remission from humanized CD19 CAR-T therapy, the patient received a maintenance therapy of donor stem cell infusion. Mild graft-versus-host disease (GVHD) manifested 24 days after infusion with an increased proportion of CD19 CAR-T cells and an increased level of CAR19 DNA expression in the peripheral blood. It fell with the remission of GVHD. The patient maintained CR and 99.69% donor chimerism during this period. ③ Throughout the subsequent donor T lymphocytes maintenance therapy, mild GVHD surfaced12 days after infusion without an increased proportion of CD19 CAR-T cells and an increased level of CAR19 DNA expression in the peripheral blood. The patient maintained CR and 99.87% donor chimerism during this period. ④ In vivo experiments on C57 mice confirmed that the proportion of CD19 CAR-T cells and the level of CAR19 DNA expression were upregulated in mice following CAR-T cell infusion, accompanied by depletion of CD19(+) B lymphocyte. After infusion of CD19(+) B lymphocyte cells, an increased proportion of CD19 CAR-T cells and an increased level of CAR19 DNA expression in the peripheral blood were observed again. Conclusions: The infusion of donor stem cells and donor T lymphocytes could be used as a maintenance treatment after CD19 CAR-T cell therapy for B-ALL patients who relapsed after allo-HSCT. Infusion of donor stem cells induced an increased proportion of CD19 CAR-T cells and an increased level of CAR19 DNA expression with the occurrence of GVHD. It might lead to further elimination of minimal residual disease.

Abstract
Background Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematopoietic malignancy. There is no standard chemotherapy regimen for BPDCN, and even allogeneic hematopoietic stem cell transplantation (allo-HSCT) has not been able to extend the survival of patients with BPDCN. Case Report Here, we present a case of recurrence of BPDCN in a patient with new nodules in his head six months after allo-HSCT. He was enrolled in a clinical trial of anti-CD123 chimeric antigen receptor (CAR) T-cell therapy (ChiCTR1900022058). However, there were no significant changes in the nodules 28 days after anti-CD123-CAR T-cell infusion. He received radiotherapy for the nodules when the proportion of anti-CD123-CAR T-cells in the peripheral blood was 2.8% and the adverse events related to the anti-CD123-CAR T-cell therapy were resolved. The proportion of anti-CD123-CAR T-cells, the level of CD123-CAR gene desoxyribonucleic acid, and the serum levels of cytokines in the patient’s peripheral blood reached the highest peak 14 days after radiotherapy. Fortunately, the nodules disappeared gradually 28 days after radiotherapy. He achieved complete remission again from the anti-CD123-CAR T-cell therapy followed by radiotherapy. To date, he has maintained progression-free survival with complete donor chimerism for six months after the combination therapy. Conclusion Anti-CD123-CAR T-cell therapy followed by radiotherapy for a recurrence of blastic plasmacytoid dendritic cell neoplasm after allo-HSCT is effective.

Abstract
Objective: To investigate the factors influencing the efficacy of CD19 chimeric antigen receptor T (CAR-T) cells in the treatment of patients with relapsed refractory B cell lymphoma and to provide evidence for further improvement of CAR-T efficacy. Methods: A total of 34 patients with relapsed and refractory B-cell lymphoma were recruited from the Department of Hematology of Tianjin First Central Hospital from February 2017 to January 2019. All patients received CD19 CAR-T cell therapy. These patients were evaluated for efficacy, factors with poor efficacyand adverse effects. Results: The overall response rate was 58.8% (20/34) and the complete remission rate was 41.2% (14/34) after infusion of CD19 CAR-T cells in 34 patients with relapsed refractory B cell lymphoma. According to the efficacy of CAR-T cells, patients were divided into two groups, 20 in the effective group and 14 in the poorly effective group. The median am ount of CD19 CAR-T cell infusions in these two groups were 8.6 (5.0-12.7)×10(6)/kg and 9.7 (5.8-15.0) × 10(6)/kg, respectively, and the difference was not statistically significant (P=0.654). The percentage of CD19 CAR-T cells in the effective group and the poorly treated group was 10.28% (3.92%-44.16%) and 4.05% (0.92%-28.63%), respectively.The effective group had a higher proportion of CAR-T cells than the poorly treated group, but the difference was not statistically significant (P=0.371).The presence of massive mass was an unfavorable factor affecting the efficacy of CD19 CAR-T cells and the difference was statistically significant (P=0.001). Logistic regression multivariate analysis showed that the characteristics of massive tumors were still independent prognostic factors for poor efficacy of CD19 CAR-T cells (P=0.005, OR=0.039). Of all 34 patients, there were 70.6% (24/34) who showed varying degrees of adverse reactions after the infusion of CD19 CAR-T cells, mainly cytokines release syndrome (CRS). The median time of occurrence of fever was on the third day after infusion (0-11th) day. 16 patients were with grade 1 CRS, 7 with grade 2, and 1 with grade 3. After glucocorticoids and support treatment, they all showed improvements. Conclusions: CD19 CAR-T cell therapy has achieved a certain effect in CD19(+)B cell lymphoma, but has poor efficacy on some patients. Large mass tumors may be an adverse factors to CAR-T cell treatment.

Abstract
Objective: To retrospectively analyze the efficacy and safety of modified cell infusion method in reducing the incidence of febrile non-hemolytic transfusion reaction (FNHTR). Methods: A total of 69 patients were enrolled in the clinical trial of CD(19) chimeric antigen receptor T (CAR-T) cell treatment from February 2017 to October 2018. Study group received the modified cell infusion method, that 1×10(6) CAR-T cells were re-suspended in 2 mg human serum albumin with total volume of 20 ml and injected intravenously. The control group was intravenously administrated with CAR-T cell in 100 ml normal saline. The incidence of FNHTR, cytokine releasing syndrome (CRS) grade, cytokine level and efficacy were compared. Results: (1)The incidence of FNHTR in the study group was 21.1%, significantly lower than that in the control group (71%)(P=0.000). (2)There was no statistical difference in cell proliferation between the study group and the control group on day 4, 7, 14 and 21 after CAR-T cell infusion (P=10.223, 3.254, 5.551, 7.605). (3)There was no statistical difference in CRS grading between the study group and the control group (P=0.767). There was no statistical difference in the levels of interleukin 2 receptor (IL-2R), IL-6, tumor necrosis factor (TNF)-α between the two groups. (4)The C-reaction protein (CRP) level of the study group was lower than that of the control group on day 4 and 7 (P=0.026, 0.007). (5)There was no statistical difference of response rates in acute lymphocytic leukemia (ALL) and non-Hodgkin lymphoma (NHL) patients between the two groups (P(ALL)=0.842; P(NHL)=0.866). Conclusion: The modified cell infusion method in CD(19) CAR-T cell treatment reduces the incidence of treatment-related FNHTR. It does not affect the proliferation of CAR-T cells in vivo, the grading of CRS and the response rates.

Abstract
Anti-CD19 chimeric antigen receptor T cell (CAR-T) therapy has changed the typical outcomes of relapsed/refractory B-cell leukemia and lymphoma. However, treatment effectiveness for patients with relapsed/refractory B-cell non-Hodgkin lymphoma has been less satisfactory compared with patients with B-cell acute lymphoblastic leukemia. The present study described a case of refractory follicular lymphoma. A high expression of programmed cell death 1 (PD-1) was measured on CD3+ T cells (80.90%) in peripheral blood samples obtained from the patient enrolled in this study, indicating that treatment with autologous CAR-T 19 cell therapy may not be successful. Therefore, a therapy regimen consisting of CAR-T 19 cells in combination with a reduced dose of nivolumab (1.5 mg/kg) for PD-1 blockade was used. A low dose of PD-1 blockade therapy was used to reduce the adverse effects associated with the combination of a PD-1 inhibitor and CAR-T 19 cells. This salvage therapy resulted in remission that lasted for >10 months.

Abstract
Objective: To evaluate the effect of a community-based intervention supporting type 2 diabetes mellitus patients in their self-management of the disease. Methods: This research was a randomized controlled trial conducted in communities in Fangshan District, Beijing, China. Adult patients with type 2 diabetes from 17 communities in 4 sub-district of Fangshan District were randomly assigned to either the intervention or control group. Participants in the intervention group participated in a three-month group-based diabetes self-management intervention service. Data were collected both in intervention and control group at baseline and after the intervention to evaluate the effect of the intervention. A questionnaire survey was completed by all participants to collect their demographic information, diabetes related health behaviors and skills. A physical examination and lab testing including height, weight, blood pressure, and waist circumference as well as HbA1c, fasting blood glucose, lipid profile were conducted before and after the intervention. Results: A total of 500 valid questionnaires were received, including 259 in the intervention group and 241 in the control group. Patients in the intervention group who learned how to conduct the self-monitoring of blood glucose increased from 56.76% (n=147) to 87.26% (n=226) after the intervention, higher than that of control group (63.07%, n=152) (P<0.001). 69.50% (n=180) patients in intervention group had blood glucose monitor at home, which was 60.62% (n=157) prior to the intervention and higher than that of control group (57.68%, n=139) (P=0.004). After the intervention, 3.09% (n=8) patients in intervention group ceased to take medicine by themselves, which was 16.22% (n=42) before the intervention, while the control group was 8.30% (n=20) after the intervention (P=0.009). Patients in the intervention group made significant improvements in implementing self monitoring on blood glucose (SMBG), which was increased from one day per week to 2 days per week, and foot self-examination, which increased from 2 days per week to 7 days per week. The body weight of patients in the intervention group reduced 1.62 kg on average after the intervention, while it increased 0.88 kg in the control group. Similar improvement was found in waist circumstance between the intervention and control group (-0.83 cm vs -0.16 m). There was a significant reduction on body weight and waist circumstance in the intervention group (P<0.05). Conclusion: The group activities focusing on people with type 2 diabetes resulted in improvement in their lifestyle and self management behaviors, as well as their body weight and waist circumstance.

Abstract
CD19 chimeric antigen receptor (CAR) T cell therapy has changed the outcomes of relapsed/refractory B‑cell leukemia and lymphoma. However, its efficacy in patients with relapsed/refractory non‑Hodgkin lymphoma (NHL) has been less impressive compared with that in patients with acute lymphoid leukemia. Furthermore, immune checkpoints have a critical role in the immune system. Several clinical trials have confirmed the dramatic effects of programmed death‑1/programmed death‑ligand 1 (PD‑1/PD‑L1) inhibitors in numerous malignancies, but the immune‑associated adverse events of PD‑1/PD‑L1 inhibitors may occur in a number of systems. The aim of the present study was to investigate the combination of CD19 CAR‑T cells with a reduced dose of PD‑1 inhibitor. This method is expected to overcome the side-effects of PD‑1 inhibitors, while maintaining therapeutic efficacy. The findings demonstrated that a reduced dose of PD‑1 inhibitor did not affect the transfection rate, proliferation rate or cytokine secretion of CD19 CAR‑T cells. An interesting finding of the present study was that the number of PD‑1‑positive cells CAR‑T cells, measured by flow cytometry, declined when they were cultured in vitro, but returned to high levels with gradual prolongation of the co‑culture time of CD19 CAR‑T cells with lymphoma cells; however, there was no change in the mRNA expression of T cells and CAR‑T cells during this process. This phenomenon may be one of the reasons why the curative effect of CAR‑T cells on B‑cell lymphoma is unsatisfactory compared with B‑cell leukemia. The synergistic effect of a reduced‑dose PD‑1 inhibitor combined with CD19 CAR‑T cells from T cells highly expressing PD‑1 was confirmed in a mouse trial. Mice in the combined treatment group achieved the longest survival time. In this group, the proportion of CAR‑T cells and the level of interleukin‑6 were higher compared with those in the CAR‑T cell group. In conclusion, a reduced dose of a PD‑1 inhibitor combined with CD19 CAR‑T cells appears to be a promising treatment option for relapsed/refractory B‑NHL exhibiting high PD‑1 expression by T cells. This method may achieve good clinical efficacy while reducing the side-effects of PD‑1 inhibitors.

Abstract
Objective: To analyze the trends on mortalities of all-cause and deaths caused by chronic and non-communicable diseases (NCDs) among Chinese labor force population during 2007 to 2016. Methods: Data on cause-of-death that collected from the National Mortality Surveillance System was used to analyze the age and area-related specific crude mortality rates, age-standardized mortality rates and component ratios of NCDs, among the Chinese labor force population, during 2007 to 2016. Trend of crude mortality rates and mortality component ratios of the three major diseases (infectious diseases, maternal and infant diseases, nutritional deficiency diseases; NCDs; injuries) were analyzed. Age-standardized mortality of cancer, COPD, cardiovascular and cerebrovascular diseases were also analyzed by gender. Age-standardized mortality was calculated based on the Year 2010 Population Census of China. Joinpoint regression model was used to obtain annual percentage change and 95%CI was set for assessing the trend. Results: In 2016, the age-standardized all-cause mortality rate was 217.23 per 100 000 among the Chinese labor force population, but decreased by -2.8% (95%CI: -3.8%- -1.7%) annually from 2007 to 2016. The gap between different gender and regions gradually narrowed. The proportion of deaths caused by NCDs increased annually by 0.8% (95%CI: 0.7%-0.9%). The age-standardized mortality rate of NCDs appeared as 171.89/100 000, among the Chinese labor force population in 2016, showing a downward trend by -2.4% (95%CI:-3.3% - -1.4%). However, in females, there appeared the greatest decrease, with an average annual change of -3.3% (95%CI:-4.0% - -2.5%). Diseases as cancer, COPD, cardiovascular and cerebrovascular diseases all showed downward trends in the whole country, with an average range of -2.0% (95%CI: -2.6%--1.3%), -8.0% (95%CI: -8.9% - -7.1%), -1.5% (95%CI: -2.9% - -0.1%), -2.3% (95%CI: -2.8% - -1.8%) in a ten-year period, respectively. Conclusion: All-cause and age-standardized mortality rates caused by NCDs among Chinese labor force population were decreasing during 2007 to 2016. However, the constituent ratios appeared increasing, year by year. Close attention needs to be paid on NCDs which affecting the health of the labor force population in China.

Abstract
Objective: To analyze the burden of disease (BOD) on diabetes attributable to high BMI in China from 1990 to 2016. Methods: Data based on population of the 2016 Global Burden of Disease Study for China were used to analyze the attributable fractions (PAF) of BOD for diabetes attributable to high BMI. Measurements for attributable BOD of diabetes included disability adjusted life years (DALY), years of lost life (YLL), years living with disability (YLD), death number and mortality rate. The average world population from 2010 to 2035 was used as a reference. Results: In 2016, death number of diabetes attributable to high BMI was 40 310, which was significantly higher than that in 1990 (15 008). Age-standardized death rate of diabetes attributable to high BMI increased from 2.01/100 000 in 1990 to 2.60/100 000 in 2016, which showed a more significant increasing trend in both males and people aged 15-49 years. DALYs of diabetes attributable to high BMI increased from 1.09 million person years to 3.30 million person years. YLL and YLD also showed increasing trends. The highest increasing rate of YLD was in people aged 15-49 years. High BMI was responsible for 26.01% of the diabetes deaths in 2016 in China, an increase of 39.39% compared with that in 1990 (18.66%). Most provinces in China experienced a sharp increase of DALY of diabetes attributable to high BMI from 1990 to 2016. Inner Mongolia, Xinjiang, Zhejiang, Macao SAR, Sichuan and Qinghai had the most significant increase tendency in terms of DALY rate during this period. Conclusions: There was a rapid increase of the deaths and mortality rate of diabetes attributable to high BMI, causing a heavy disease burden, in China from 1990 to 2016. The BOD varied in both different age and gender groups. More attention should be paid to males and people aged 15-49 years in the prevention and control programs of diabetes.

Abstract
Objective: To assess the disease burden for gynecological disease in China in 2016. Methods: Data were extracted from the global burden of disease study 2016 (GBD 2016) . The burden of gynecological disease among age groups and provinces groups was assessed by prevalence rate, mortality rate, years lived with disability (YLD) , years of life lost due to premature mortality (YLL) and disability-adjusted life years (DALY) . An average world population age-structure for the period 2010-2035 was adopted to calculate age-standardized rates. Results: In 2016, the prevalence rate of gynecological disease in women aged 15 years and above in China was 24.94%, of which was 36.71% to women of childbearing age. The number of DALY from gynecological disease was 2 727 637.82 life years in 2016, with the DALY rate was 411.12/100 000 and standardized DALY rate was 341.80/100 000. The first three gynecological diseases with highest DALY and DALY rate among Chinese women aged ≥15 years were premenstrual syndrome (815 004.64 life years, 122.84/100 000) , uterine fibroids (281 976.67 life years, 42.5/100 000) and endometriosis (154 792.89 life years, 23.33/100 000) . The DALY caused by gynecological disease in Guangdong (220 871.19 life years) , Shandong (190 968.72 life years) , Henan (171 273.92 life years) , Jiangsu (168 404.27 life years) and Sichuan (144 358.5 life years) were higher than other provinces. The standardized DALY rate attributable to gynecological disease were highest in Xinjiang Uygur Autonomous Region (404.00/100 000) , Shanghai (394.90/100 000) , Heilongjiang (382.00/100 000) , Beijing (365.70/100 000) and Jiangsu (357.50/100 000). Conclusions: Gynecological disease is a great threat to women's reproductive health. Effective measures should be taken to address the issue, especially to women of childbearing age.

Abstract
In February 1906, Union Medical College (UMC, Peking) held the opening ceremony. The establishment and operation of the College was mostly attributed to Thomas Cochrane (1866-1953) from London Missionary Society. As a medical missionary in China, Cochrane lived through the dramatic political and social changes in the modern history of China and the world.As an English medical missionary, he witnessed and experienced the extreme poverty and severe shortage of medicine of the Chinese people when he was in Chaoyang, Liaoning Province, most inhabited by the Mongolian ethnic group. Then, he survived the Boxer Movement which with great resentment toward Christianity massacred the Chinese and foreign missionaries. After that, he approached to and then won over the trust and appreciation of the highest ruler of the Qing Dynasty. After the establishment of Republic of China, he handed over in person the college established by himself to the philanthropic organization of American capitalist. Cochrane's less than 30 years of life in China mirrored the great political, social, healthy, educational, intellectual, and ideological changes in China that shaped the medicine and health at the turn of the 20(th) century.

Abstract
Objective: To analyze the deaths attributable to alcohol use and its impact on people's life expectancy in China in 2013. Methods: The mortality data from the Disease Surveillance Points System and alcohol use data from China Chronic Disease Surveillance (2013) were used. The deaths attributed to alcohol use and its impact on the life expectancy of Chinese residents were estimated based on the principle of comparative risk assessment by calculating population attributable fraction. Results: In 2013, alcohol use resulted in 381 200 deaths, including 97 100 hemorrhagic stroke deaths, 88 200 liver cancer deaths, 61 400 liver cirrhosis deaths and 48 700 esophageal cancer deaths, and prevented 76 500 deaths, including 68 500, 4 900 and 3 100 deaths which might be caused by ischemic heart disease, hemorrhagic stroke and diabetes respectively. If risk factor of alcohol use is removed, the people's life expectancy would rise by an average of 0.43 years, especially in western China by 0.52 years, which was 0.12 years higher than that in eastern and central China, and the life expectancy of the population in rural and urban areas would rise by 0.48 years and 0.31 years respectively. Conclusions: Although alcohol has a protective effect on reducing ischemic heart disease, stroke and diabetes deaths, alcohol use is still a risk factor influencing the mortality and life expectancy of residents in China. It is necessary to take targeted measures to reduce the health problems caused by harmful use of alcohol.

Abstract
Objective: To investigate the screening of serum biomarkers in patients with HBV-related acute-on-chronic liver failure (HBV-ACLF) by isobaric tags for relative and absolute quantitation (iTRAQ). Methods: Gel electrophoresis was used to isolate and remove high-abundant proteins. Each group of peptides was labeled by the iTRAQ reagents and then tested with an UltiMateTM 3000 nanoliter high-performance liquid chromatograph, and a Q-Exactive tandem mass spectrometer. The Protein Discovery software was used to analyze mass spectrometry data and perform bioinformatic analysis for differentially expressed proteins. Results: Ten samples each were included in the HBV-ACLF group and the chronic hepatitis B (CHB) group, and six samples each were included in the HBV-ACLF survival group and the HBV-ACLF death group. Compared with the CHB group, the HBV-ACLF group had 43 differentially expressed proteins, among which 34 were downregulated and 9 were upregulated. Compared with the HBV-ACLF survival group, the HBV-ACLF death group had 33 differentially expressed proteins, among which 18 were upregulated and 15 were downregulated. Conclusion: Keratin,α1-acid glycoprotein, and zinc-α2-glycoprotein identified in the serum may be used as potential biomarkers for predicting the prognosis of patients with HBV-ACLF.

Abstract
OBJECTIVE To study the expression of hypoxia inducible factor 1α(HIF-1α) of iron-overloaded in irradiated mice and its effect on erythropoiesis. METHODS Twenty mice were randomly divided into 4 groups: Ctrl (control group), IR (irradiation group), IO (irradiation + iron overload group), and RAPA (rapamycin treatment group). The iron overload model was verified. The CFU-E (colony forming unit-erythroid) and BFU-E(burst colony forming unit-erythroid) were cultured; flow cytometry was used to detect the ratios of early stage (Ter119+CD71-) to late stage (Ter119+CD71+) of primitive erythroblasts; RT-PCR was used to detect the mRNA expression of HIF-1α and its related signal molecules in bone marrow cells. RESULTS The expression of HIF-1α in IR and IO group was significantly higher than that in Ctrl group, and that in IO group was significantly higher than IR group (P<0.05). The ratio of late stage primitive erythroblasts, the number of CFU-E and BFU-E in both IR and IO group were lower than those in Ctrl group, and those in IO group were significantly lower than those in IR group (P<0.05). Compared with Ctrl group, the expression of HIF-1α related signal pathway molecules in both IR and IO group was significantly decreased (P<0.05). Compared with IO group, the expression of HIF-1α and its related signal molecules in RAPA(mTOR inhibitor) group was decreased significantly (P<0.05), the number of BFU-E was increased significantly(P<0.05). CONCLUSION Irradiation induces the increase of HIF-1α and the decrease of the ability of hematopoietic colony formation and the ratio of late stage primitive erythroblasts. Iron overload can aggravate the injury. mTOR inhibitor rapamycin can partially alleviate the injury, suggesting that iron overload can lead to injury of erythropoiesis through HIF-1α.

Abstract
Objective: To understand the 'backward' provinces and the relatively poor work among the construction of National Demonstration Area, so as to promote communication and future visions among different regions. Methods: Methods on Cluster analysis were used to compare the development of National Demonstration Area in different provinces, including the coverage of National Demonstration Area and the scores of non-communicable disease (NCDs) prevention and control work based on a standardized indicating system. Results: According to the results from the construction of National Demonstration Area, all the 29 provinces and the Xinjiang Production and Construction Corps (except Tibet and Qinghai) were classified into 6 categories: Shanghai; Beijing, Zhejiang, Chongqing; Tianjin, Shandong, Guangdong and Xinjiang Production and Construction Corps; Hebei, Fujian, Hubei, Jiangsu, Liaoning, Xinjiang, Hunan and Guangxi; Shanxi, Jilin, Henan, Hainan,Sichuan, Anhui and Jiangxi; Inner Mongolia, Shaanxi, Ningxia, Guizhou, Yunnan, Gansu and Heilongjiang. Based on the scores gathered from this study, 24 items that representing the achievements from the NCDs prevention and control endeavor were classified into 4 categories: Manpower, special day on NCD, information materials development, policy/strategy support, financial support, mass media, enabled environment, community fitness campaign, health promotion for children and teenage, institutional structure and patient self-management; healthy diet, risk factors on NCDs surveillance, tobacco control and community diagnosis; intervention of high-risk groups, identification of high-risk groups, reporting system on cardiovascular and cerebrovascular events, popularization of basic public health service, workplace intervention programs, construction of demonstration units and mortality surveillance; oral hygiene and tumor registration. Contents including oral hygiene, tumor registration, intervention on high-risk groups, identification of high-risk population, reporting system on cardiovascular and cerebrovascular events, popularization of basic public health service, workplace intervention programs, construction of demonstration units and mortality surveillance were discerned as the relatively weak areas in the construction programs of National Demonstration Area. Conclusions: Western regions, especially in some remote provinces had the poorest performance during the construction of National Demonstration Area. Programs regarding chronic disease surveillance, identification and intervention on high-risk groups showed the lowest scores and these outcome-oriented tasks should be further focused on, during the next term of review, in these areas.

Abstract
The objective of this study is to investigate the effect of B vitamins-fortified foods on primary school children. A controlled trial was conducted in 101 normal primary school children aged 9-11 years. They were randomly assigned to supplemental control group (S-control, n=36), riboflavin supplementation group (+riboflavin 0.625 mg/day, n=32), and B vitamin compound supplementation group (+riboflavin 0.625 mg/day, +thiamin 0.512 mg/day, +nicotinic acid 0.365 mg/day, +folic acid 0.13 mg/day, n=33) based on school classes. Urinary riboflavin excretion and erythrocyte glutathione reductase activity coefficient (EGRAC) along with erythrocyte transketolase activity (ETKA) were used to evaluate B vitamin levels in the children. AYP index, an index reflecting the brain performance ability, was chosen to assess the children's study abilities. Health education was carried out to help children and their parents adopt scientific dietary concepts. The urinary riboflavin excretion was higher in two supplementation groups (435.24 +/- 153.3 microg/g creatinine, 374.6 +/- 144.6 microg/g creatinine) than in S-control group (235.1 +/- 86.2 microg/g creatinine). Average values of EGRAC were lower in two supplementation groups (0.90 +/- 0.11, 0.80 +/- 0.10) than in S-control group (1.08 +/- 0.25). At the same time, the percentage of thiamine pyrophosphate (TPP%) decreased from 63.69 +/- 28.04 to 42.16 +/- 16.31 in B vitamin compound supplementation group. Meanwhile, AYP index increased at the end of the supplementation in two supplementation groups. B vitamins supplementation can significantly increase B vitamin level in children. Biochemical activities of riboflavin and thiamin can improve with the intake of fortified foods. The effect of B vitamin compound supplementation is better than that of single riboflavin supplementation when the effect of riboflavin's biofunction is considered. In addition, micronutrient supplementation appears to assist children's study abilities.

Abstract
OBJECTIVE To investigate the effects of iron overload on apoptosis and function of splenic CD8+ T cells in mice. METHODS Forty C57BL/6 mice were randomly divided into control groups, Iron overload (IO), IO+NAC and IO+DFX groups. The iron overload model was established by intraperitoneal injection of iron dextran, and saline was injected as the control. The levels of intracellular reactive oxygen species (ROS) and labile iron pool (LIP) were analyzed by measuring the mean fluorescence intensity (MFI) of 2-7 dichlorofluorescein (DCF) or calcein. The ratio of CD8+ T cells and the levels of IFN-γ, TNF-α, Granzyme-B, and perforin in CD8+ T cells were detected by flow cytometry. The CD8+ T cell apoptosis was determined by flow cytometry with Annexin V/PI double staining. Real-time PCR was used to detect the expression of IFN-γ, TNF-α, Granzyme-B, perforin, BCL-2, and bax at mRNA level in CD8+ T cells. RESULTS Iron overload was found by spleen iron staining and flow cytometry. The level of intracellular ROS in iron overload (IO) groups was higher than that of the control groups (P<0.01). The percentage of CD8+ T cells in spleen from mice with IO was lower than that in control groups (P<0.05). The expression of IFN-γ and Granzyme-B in CD8+ T cells in IO group were lower than that in control group, the expression of IFN-γ and Granzyme-B at mRNA level in CD8+ T cells was lower than that of control group (P<0.05). CD8+ T cell apoptosis in iron overload group was significantly higher than that in control groups (P<0.01); the expression of BCL-2 at mRNA level was lower than that in control group, but the expression of BAX at mRNA level was higher than that in control group (P<0.05). These effects could be reversed after treating iron-overloaded mice with DFX or NAC. CONCLUSION Iron overload can inhibit the ratio of CD8+ T cells of splenic cells in mice, decrease the expression of IFN-γ, Granzyme-B, increase the apoptosis of CD3+ CD8+/CD8-. These effects may be regulated through increasing the intracellular ROS level, and can be partially reversed after treating iron-overloaded mice with DFX or NAC.

Abstract
OBJECTIVE To establish macrophage iron overload model in vitro by co-culture macrophages with iron, and to explore the effect of iron overload on cell reactive oxygen species (ROS) and the impact of ROS on macrophages. METHOD Iron overload group were treated with different concentrations (0, 5, 10, 20, 40, 80 μmol/L respectively) of ferric ammonium citrate (FAC). The control group was the group of macrophages without FAC treatment. We detected the number and state of cells, metabolic activity, the change of phagocytosis, the levels of ROS and reactive nitrogen, and changes of related oxidative stress signaling pathways in different groups. Changes in the above indexes were detected after application of deferasirox (DFX) to remove iron and the antioxidant N -acetylcysteine (NAC) to clear excess oxidative stress. RESULTS (1)The levels of labile iron pool (LIP) in macrophages co-cultivated with iron was increased with the increase of iron concentration in a dose-dependent manner. The LIP levels was the highest in the macrophages treated with 80 μmol/L. (2)The increase of FAC concentration, the metabolic activity of macrophages in the 5 FAC-treated groups decreased to 51.58%, 40.98%, 16.23%, 3.46%, and 0.05% of the activity level of the control group (all P< 0.05). The group with the metabolic activity decreased to 16.23% (20 μmol/L) was selected as the iron overload group for the following experiments. (3)Compared with the control group, the number of macrophages in the iron overload group reduced to 32.80% (P<0.05), and the state of cells changed from adherence to partial suspension. The phagocytosis of macrophages in the iron overload group reduced to 20.40% of the control group (P<0.05). (4)Our further experiment showed that the levels of ROS and the activity nitrogen in the iron overload group increased by 7.71-and 1.45-fold compared with the control group (both P<0.05). The RT-PCR showed up-regulated mRNA expression of genes related with ROS production, i. e. nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX 4) gene related with ROS production and inducible nitric oxide synthase (iNOS) gene related with reactive nitrogen production, down-regulated mRNA expression of glutathione peroxidase 1 (GPX1) gene which participated in ROS clearance. Moreover, mRNA expression of phosphatidylinositol-3-kinase (PI3K) gene involved in oxidative stress signaling pathway in the iron overload group was up-regulated, while fork head protein O3 (FOXO3) which regulated oxidative stress through negative feedback showed a down-regulation level of mRNA expression compared with the control group. (5)After iron chelation and antioxidant treatment, the above-mentioned damage in the iron overload group were partially reversed. CONCLUSIONS The damages of iron overload on macrophages may be mediated by inducing oxidative stress and activating oxidative stress signaling pathways. Our established model provides a method to explore the mechanism of iron overload on macrophage, and may shed some new light on possible therapeutic target in treating iron overload patients.

Abstract
Anomalies of the local structural order in quasi-two-dimensional liquid silicon upon cooling are investigated. Results show that the appearance of the left subpeak in pair correlation functions is the signature of the liquid-liquid phase transition (LLPT). The structural origin of the LLPT is the formation of a crystal-like ordered structure with a short-range scale, which in turn forms the local well-organized paracrystalline region. Unlike in the bulk liquid silicon, the stages of the LLPT and liquid-solid phase transition (LSPT) in the quasi-two-dimensional liquid silicon do not overlap. The crystal-like ordered structures formed in the LLPT are precursors which are prepared for the subsequent LSPT. Also observed was a strong interconnection between the local well-organized paracrystalline region and the transition from the typical metal to the semimetal in the two-dimensional silicon. This study will aid in better understanding of the essential phase change in two-dimensional liquid silicon.

Abstract
In order to study the new technique of plasma wastewater treatment, the degradation behaviour ofnitenpyram (NTP) pesticide was investigated in a low-temperature plasma formed during a dielectric barrier discharge process. The reactor was a radial flow sedimentation tank centred around the water inlet. We studied the effect of pesticide concentration and input power of the dielectric barrier discharge, together with the effect of external factors on the degradation of nitenpyram pesticide wastewater such as conductivity and the use of various of catalysts, and the reaction products were analyzed by high-performance liquid chromatography mass spectrometry (HPLC-MS). The results showed that NTP could be effectively removed from aqueous solution by low-temperature plasma. Increasing the input power could improve the efficiency of degradation, conforming to a first-order kinetic model. Use of a suitable catalyst clearly improved the degradation process, as also did low conductivity. The pH of NTP was reduced with discharge time.

Abstract
BACKGROUND Endothelial permeability is involved in injury, inflammation, diabetes and cancer. It is partly regulated by the thrombin-, histamine-, and VEGF-mediated myosin-light-chain (MLC) activation pathways. While these pathways have been investigated, questions such as temporal effects and the dynamics of multi-mediator regulation remain to be fully studied. Mathematical modeling of these pathways facilitates such studies. Based on the published ordinary differential equation models of the pathway components, we developed an integrated model of thrombin-, histamine-, and VEGF-mediated MLC activation pathways. RESULTS Our model was validated against experimental data for calcium release and thrombin-, histamine-, and VEGF-mediated MLC activation. The simulated effects of PAR-1, Rho GTPase, ROCK, VEGF and VEGFR2 over-expression on MLC activation, and the collective modulation by thrombin and histamine are consistent with experimental findings. Our model was used to predict enhanced MLC activation by CPI-17 over-expression and by synergistic action of thrombin and VEGF at low mediator levels. These may have impact in endothelial permeability and metastasis in cancer patients with blood coagulation. CONCLUSION Our model was validated against a number of experimental findings and the observed synergistic effects of low concentrations of thrombin and histamine in mediating the activation of MLC. It can be used to predict the effects of altered pathway components, collective actions of multiple mediators and the potential impact to various diseases. Similar to the published models of other pathways, our model can potentially be used to identify important disease genes through sensitivity analysis of signalling components.

Abstract
Multitarget agents have been increasingly explored for enhancing efficacy and reducing countertarget activities and toxicities. Efficient virtual screening (VS) tools for searching selective multitarget agents are desired. Combinatorial support vector machines (C-SVM) were tested as VS tools for searching dual-inhibitors of 11 combinations of 9 anticancer kinase targets (EGFR, VEGFR, PDGFR, Src, FGFR, Lck, CDK1, CDK2, GSK3). C-SVM trained on 233-1,316 non-dual-inhibitors correctly identified 26.8%-57.3% (majority >36%) of the 56-230 intra-kinase-group dual-inhibitors (equivalent to the 50-70% yields of two independent individual target VS tools), and 12.2% of the 41 inter-kinase-group dual-inhibitors. C-SVM were fairly selective in misidentifying as dual-inhibitors 3.7%-48.1% (majority <20%) of the 233-1,316 non-dual-inhibitors of the same kinase pairs and 0.98%-4.77% of the 3,971-5,180 inhibitors of other kinases. C-SVM produced low false-hit rates in misidentifying as dual-inhibitors 1,746-4,817 (0.013%-0.036%) of the 13.56 M PubChem compounds, 12-175 (0.007%-0.104%) of the 168 K MDDR compounds, and 0-84 (0.0%-2.9%) of the 19,495-38,483 MDDR compounds similar to the known dual-inhibitors. C-SVM was compared to other VS methods Surflex-Dock, DOCK Blaster, kNN and PNN against the same sets of kinase inhibitors and the full set or subset of the 1.02 M Zinc clean-leads data set. C-SVM produced comparable dual-inhibitor yields, slightly better false-hit rates for kinase inhibitors, and significantly lower false-hit rates for the Zinc clean-leads data set. Combinatorial SVM showed promising potential for searching selective multitarget agents against intra-kinase-group kinases without explicit knowledge of multitarget agents.

Abstract
Abl promotes cancers by regulating cell morphogenesis, motility, growth, and survival. Successes of several marketed and clinical trial Abl inhibitors against leukemia and other cancers and appearances of reduced efficacies and drug resistances have led to significant interest in and efforts for developing new Abl inhibitors. In silico methods of pharmacophore, fragment, and molecular docking have been used in some of these efforts. It is desirable to explore other in silico methods capable of searching large compound libraries at high yields and reduced false-hit rates. We evaluated support vector machines (SVM) as a virtual screening tool for searching Abl inhibitors from large compound libraries. SVM trained and tested by 708 inhibitors and 65,494 putative noninhibitors correctly identified 84.4 to 92.3% inhibitors and 99.96 to 99.99% noninhibitors in 5-fold cross validation studies. SVM trained by 708 pre-2008 inhibitors and 65 494 putative noninhibitors correctly identified 50.5% of the 91 inhibitors reported since 2008 and predicted as inhibitors 29,072 (0.21%) of 13.56M PubChem, 659 (0.39%) of 168K MDDR, and 330 (5.0%) of 6638 MDDR compounds similar to the known inhibitors. SVM showed comparable yields and substantially reduced false-hit rates against two similarity based and another machine learning VS methods based on the same training and testing data sets and molecular descriptors. These suggest that SVM is capable of searching Abl inhibitors from large compound libraries at low false-hit rates.

Abstract
Fungal infection is a major cause of death in patients who undergo organ transplantation. The incidence of Aspergillus or Mucor infection is low compared with Candida species. We report a case in which Aspergillus and Mucor infected both the hepatic and renal arteries, leading the 2 arteries to rupture at the same time. The patient died 4 days after the second operation. We review the recent literature about this topic and explore the possible route of transmission in our patient. We also discuss the prophylactic methods for Aspergillus and Mucor infections.

Abstract
INTRODUCTION The Candida albicansTHI13 gene was identified by its homology to the Candida tropicalis CtNMT1 gene, which is involved in pyrimidine precursor biosynthesis. METHODS Disruption of THI13 revealed that this gene played a minor role in thiamin biosynthesis in C. albicans. Purified human monocytes were incubated with C. albicans at the optimal Candida: monocyte ratio of 0.5 and cytokines in the supernatants were measured by enzyme-linked immunosorbent assay. RESULTS AND DISCUSSION This experiment showed that the wild-type strain significantly induced interleukin-10 (IL-10) production but had little effect on IL-12 production, and that THI13 mutants had no significant effect on IL-10 production, though the IL-12 level was increased in the supernatants. These results suggest that THI13 is involved in the host effective immune response by regulating IL-10 and IL-12 production.

Abstract
A series of N-diisopropylphosphoryl (DIPP) L-amino acid ester prodrugs of zidovudine (AZT) (3a-3e) and stavudine (d4T) (4a-4e) has been prepared. The activity of these compounds against MCF-7 cells (human pleural effusion breast adenocarcinoma cell line) and K562 cells (human chronic myeloid leukemia (CML) cell line) was evaluated. In difference from that of AZT amino acid phosphoramidates, the alophatic amino acid esters of AZT were found to be more cytotoxic than the aromatic analogues toward MCF-7 cell. Two DIPP-L-amino acid esters of d4T 4b (CC50 = 83 microM) and 4c (CC50 = 182 microM) were found to be more cytotoxic than the parent drug toward K562 cells. MCF-7 and K562 cell cycle disturbance was investigated showing detectable blockade in the S phase when exposed to biologically active AZT, 3a, 3b, 3c, 4b and 4c, indicating that they inhibit cell growth by blocking cell cycle progression. Together with previous reports, present findings suggest that anti-breast cancer activity of AZT may be due to hamper DNA synthesis.
