Abstract
BACKGROUND The pathophysiology and the potential risks of placental transfusion (PT) differ substantially in preterm infants, necessitating specific studies in this population. This study aimed to evaluate the safety and efficacy of PT in preterm infants from the perspective of long-term neurodevelopmental outcomes. METHODS We conducted a systematic literature search using placental transfusion, preterm infant, and its synonyms as search terms. Cochrane Central Register of Controlled Trials, Medline, and Embase were searched until March 07, 2023. Two reviewers independently identified, extracted relevant randomized controlled trials, and appraised the risk of bias. The extracted studies were included in the meta-analysis of long-term neurodevelopmental clinical outcomes using fixed-effects models. RESULTS A total of 5612 articles were identified, and seven randomized controlled trials involving 2551 infants were included in our meta-analysis. Compared with immediate cord clamping (ICC), PT may not impact adverse neurodevelopment events. No clear evidence was found of a difference in the risk of neurodevelopmental impairment (risk ratio [RR]: 0.89, 95% confidence interval [CI]: 0.76 to 1.03, P = 0.13, I2 = 0). PT was not associated with the incidence of cerebral palsy (RR: 1.23, 95% CI: 0.59 to 2.57, P = 0.79, I2 = 0). Analyses showed no differences between the two interventions in cognitive, language, and motor domains of neurodevelopment. CONCLUSIONS From the perspective of long-term neurodevelopment, PT at preterm birth may be as safe as ICC. Future studies should focus on standardized, high-quality clinical trials and individual participant data to optimize cord management strategies for preterm infants after birth.

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 The disease burden of gastrointestinal disease (GD) in China is high, with significant variation across provinces. A comprehensive agreed set of indicators could guide rational resource allocation to support better GD outcomes. Methods This study collected data from multiple sources, including national surveillance, surveys, registration systems, and scientific research. Literature reviews and Delphi methods were used to obtain monitoring indicators; the analytic hierarchy process was used to determine indicator weights. Findings The China Gastrointestinal Health Index (GHI) system consisted of four dimensions and 46 indicators. The weight of the four dimensions from high to low included the prevalence of gastrointestinal non-neoplastic diseases and gastrointestinal neoplasms (GN) (0.3246), clinical treatment of GD (0.2884), prevention and control of risk factors (0.2606), and exposure to risk factors (0.1264). The highest indicator weight of GHI rank was the successful smoking cessation rate (0.1253), followed by the 5-year survival rate of GN (0.0905), and the examination rate of diagnostic oesophagogastroduodenoscopy (0.0661). The overall GHI for China in 2019 was 49.89, varying from 39.19 to 76.13 across all sub-regions. The top five sub-regions in the total GHI score were in the eastern region. Interpretation GHI is the first system designed to monitor gastrointestinal health systematically. In the future, data from sub-regions of China should be used to test and improve the GHI system for its impact. Funding This research was supported by the National Health Commission of China, the First Affiliated Hospital of Naval Medical University (2019YXK006), and the Science and Technology Commission of Shanghai Municipality (21Y31900100).

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
PURPOSE This study focused on the role and mechanism of IGF2BP1 in cell cisplatin resistance of oral squamous cell carcinoma. METHODS Low-dose intermittent induction method was used to induce cisplatin-sensitive oral squamous cell carcinoma cell line HN30, and establish cisplatin-resistant cell line HN30/DDP. Western blot was used to detect the protein expression level of IGF2BP1 in parental and resistant cell line. Knockdown or overexpression of IGF2BP1 by RNAi and lentivirus transfection method was utilized to analyze the effect of decreased or increased the gene expression of IGF2BP1 on cisplatin resistance. MTT method was used to detect the change of IC50. Statistical analysis of data was performed using SPSS 17.0 software package. RESULTS Cisplatin-resistant oral squamous cell carcinoma cell line was successfully established. The IC50 of the drug-resistant cells was significantly higher than that of the parental cells. Knocking down the expression level of IGF2BP1 in drug-resistant strains reduced cell resistance; on the contrary, after overexpression of IGF2BP1 in parental cells dramatically increased cisplatin resistance. Mechanically, activation of Akt signaling pathway was the key factor mediating IGF2BP1 to promote cisplatin resistance in oral squamous cell carcinoma. CONCLUSIONS IGF2BP1 is significantly associated with cisplatin resistance in oral squamous cell carcinoma. IGF2BP1 can promote cisplatin resistance of oral squamous cells by activating downstream Akt signaling pathway.

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
INTRODUCTION The rapid rise in the prevalence of diabetes has a negative impact on patients' quality of life. Diabetes self-management group education is cost-effective and efficient for patients to control blood glucose. However, there are no consistent standards for self-management group education, and its long-term effects (≥12 months) are unclear. Although a few systematic reviews evaluated the long-term effects, they did not make clear provisions on the content of self-management, and the number and sample size of included studies were small, which may lead to misclassification bias and reporting bias. Therefore, we plan to conduct this systematic review to evaluate the long-term effects of self-management group education and determine the effects of different self-management characteristics on glycosylated haemoglobin (HbA1c). METHODS AND ANALYSIS We will retrieve Chinese databases (Wanfang, Chinese Hospital Knowledge Warehouse) and English databases (PubMed, ScienceDirect, EMBASE, Web of Science, Bailian Platform, Cochrane Central Register of Controlled Trials, Google Scholar) for randomly controlled trials and cluster randomly controlled trials of which participants are adults with type 2 diabetes mellitus. We will manually search citation lists and trial registries, and consult authors to obtain relevant articles. The retrieval time range will be from the establishment of the database to July 2020 to avoid omitting relevant studies. The primary outcome will be HbA1c. The secondary outcomes will be fasting plasma glucose, postprandial blood glucose, total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, systolic blood pressure, diastolic blood pressure, body mass index, waist circumference and death event. Two reviewers will independently conduct article screening and assessment of risk of bias, with a third reviewer arbitrating if necessary. We will give priority to the use of meta-analysis to evaluate the pooled effects of all outcomes. For the outcomes of unrecognised sources of heterogeneity, missing data and less than three related studies, narrative synthesis approach will be used. ETHICS AND DISSEMINATION Ethical approval is not required for this systematic review. We plan to present the findings in a peer-reviewed scientific journal, relevant and responsible organisations, and training meetings. PROSPERO REGISTRATION NUMBER CRD42020209011.

Abstract
A nano-calcium peroxide (nCaO2) powder with a purity of 89.1% was prepared using an improved traditional method. Then, the as-prepared nCaO2 was used as the source of hydrogen peroxide (H2O2) for the Fenton-like degradation of diclofenac sodium (DCF). The results showed that nCaO2 performed better for DCF removal when compared to nCaO2 prepared by a conventional method and commercial calcium peroxide (CaO2). Further experimental results indicated that 97.5% of DCF could be removed in 180 min at a nCaO2/Fe2+-EDTA/DCF molar ratio of 16/8-8/1, which was more efficient than in the H2O2/EDTA-Fe2+/DCF and nCaO2/Fe2+/DCF systems. The best removal rate of DCF was at pH 6.0, unlike previous claims that stated that the lower the pH in the buffer system, the better the degradation of DCF. In addition, the influence of water quality parameters, such as Cl-, NO3-, SO42-, HCO3-, and humic acid (HA), on DCF removal were evaluated. A free radical masking experiment revealed the existence of hydroxyl radical (OH), superoxide radical (O2-) and singlet oxygen (1O2), and indicated that the degradation of DCF was mainly due to oxidation caused by OH. Electron paramagnetic resonance (EPR) studies for different systems and different active oxygen species were carried out, and it was further confirmed that OH radicals have high intensity in the Fenton-like system based on nCaO2. EPR results also showed that the addition of EDTA can promote the production of OH. According to the identification of the dominant reactive species and GC-MS, the possible theoretical DCF degradation pathways were proposed.

Abstract
Background: ET-26 hydrochloride (ET-26HCl), a class 1 new drug, was developed to reserve the advantages of etomidate with a mild adrenocortical inhibition. Purpose: this study was to evaluate the potential adverse effects on the cardiovascular system of beagle dogs and the respiratory and central nervous systems of rats. Methods: three established methods, the whole-body plethysmography for respiratory function, the prototype telemetry transmitter for cardiovascular function, and the standardized functional observational battery for central nervous system function, were accomplished with Good Laboratory Practice standards. Results: no significant difference in the tidal volume, but the respiratory rate and minute ventilation were reduced. The degree of inhibition was the most serious in the first 15 min after dosing and function fully recovered after 1 h. For male rats, the respiratory rate of male rats was reduced significantly at 15 min after injection with ET-26HCl (4 mg/kg, 28.6%, p ≤ 0.01; 8 mg/kg, 24.5%, p ≤ 0.01; 16 mg/kg, 44.5%, p ≤ 0.001), and the minute ventilation at 15 min was decreased by 20.1% (4 mg/kg, p = 0.034), 22.2% (8 mg/kg, p = 0.019), and 44.6% (16 mg/kg, p ≤ 0.001) as compared to control group. As with male rats, the respiratory rate of the female rats was reduced significantly at 15 min (4 mg/kg, 23.3%, p ≤ 0.01; 8 mg/kg, 29.2%, p ≤ 0.001; 16 mg/kg, 44.1%, p ≤ 0.001), and the minute ventilation was decreased by 25.2% (4 mg/kg, p ≤ 0.001), 23.0% (8 mg/kg, p ≤ 0.01), and 47.6% (16 mg/kg, p ≤ 0.001). Then, all the variations in cardiovascular functions were within the expected range for normal biological variation, we concluded that ET-26HCl, even at 10-fold ED50, still does not exert toxicological effects on the cardiovascular system. For male beagle dogs, the systolic blood pressure after 24 h following administration of vehicle control or 8, 12, or 16 mg/kg ET-26HCl was 137.80 ± 5.55, 131.76 ± 10.03, 139.88 ± 8.35, and 141.28 ± 8.75 mmHg, respectively. The diastolic blood pressure was 71.16 ± 4.84, 66.52 ± 8.50, 73.64 ± 8.51, and 74.24 ± 8.68 mmHg, respectively. For female beagle dogs, the systolic blood pressure after 24 h following administration of vehicle control or 8, 12, or 16 mg/kg ET-26HCl was 128.28 ± 5.22, 124.76 ± 7.29, 134.88 ± 5.56, and 135.36 ± 8.72 mmHg, respectively. The diastolic blood pressure was 67.00 ± 4.10, 62.12 ± 7.87, 69.44 ± 6.40, and 70.20 ± 8.42 mmHg, respectively. In central nervous system function experiment, all the changes observed in the functional observational battery tests, including motor activity, behavior, coordination, and sensory and motor reflex responses, and reduced body temperature, were resulted in general anesthesia effect of ET-26HCl. Conclusion: ET-26HCl exerts mild, reversible effects on respiratory, cardiovascular, and central nervous system function as verified by standard in vivo animal models.

Abstract
BACKGROUND Alisol A 24-acetate (AA-24-a), one of the main active triterpenes isolated from the well-known medicinal plant Alisma orientale (Sam.) Juz., exhibits multiple biological activities including hypolipidemic activity. However, its effect on lipid metabolism in adipocytes remains unclear. The present study aimed to clarify the effect of AA-24-a on adipocyte lipolysis and to determine its potential mechanism of action using 3 T3-L1 cells. METHODS We assayed the release of glycerol into culture medium of 3 T3-L1 cells under treatment with AA-24-a. Protein and mRNA expression and phosphorylation levels of the main lipases and kinases involved in lipolysis regulation were determined by quantitative polymerase chain reaction and western blotting. Specific inhibitors of protein kinase A (PKA; H89) and extracellular signal-regulated kinase (ERK; PD98059), which are key enzymes in relevant signaling pathways, were used to examine their roles in AA-24-a-stimulated lipolysis. RESULTS AA-24-a significantly stimulated neutral lipolysis in fully differentiated adipocytes. To determine the underlying mechanism, we assessed the changes in mRNA and protein levels of key lipolysis-related genes in the presence or absence of H89 and PD98059. Both inhibitors reduced AA-24-a-induced lipolysis. Moreover, pretreatment with H89 attenuated AA-24-a-induced phosphorylation of hormone-sensitive lipase at Ser660, while pretreatment with PD98059 attenuated AA-24-a-induced downregulation of peroxisome proliferator-activated receptor-γ and perilipin A. CONCLUSIONS Our results indicate that AA-24-a promoted neutral lipolysis in 3 T3-L1 adipocytes by activating PKA-mediated phosphorylation of hormone-sensitive lipase and ERK- mediated downregulation of expression of perilipin A.

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
Algal organic matter (AOM) and natural organic matter (NOM) from a typical eutrophic lake were comprehensively investigated in terms of their physico-chemical property, components and disinfection byproduct formation potentials (DBPFPs). The relationships between specific chemical properties of AOM and NOM with their corresponding DBPFPs were further evaluated during chlorination. Results indicated that AOM had lower specific UV absorbance (SUVA) but richer organic nitrogen contents than NOM. Fluorescence excitation emission matrix spectroscopy further demonstrated that AOM were chiefly composed of aromatic protein-like and soluble microbial byproduct-like matters, while NOM were mainly contributed from humic acid-like and soluble microbial byproduct-like substances. Although the molecular weight (MW) distribution of AOM and NOM showed no significant difference, size-exclusion chromatography with organic carbon as well as organic nitrogen detection (LC-OCD-OND) revealed that AOM were concentrated with the fraction of building blocks and NOM had higher concentrations of biopolymers and humics (HS). Moreover, AOM displayed higher DBPFPs than NOM, especially for nitrogenous DBPFP (N-DBPFP). MW < 1 kDa fractions both in AOM and NOM contributed the largest proportion to the formation of carbonaceous disinfection byproducts (C-DBPs). In addition, Pearson correlation analysis showed that bulk parameter SUVA was significantly relevant to the formation potentials of trihalomethane both in AOM and NOM, but was ineffective for carbonaceous DBPFP (C-DBPFP) prediction. Dissolved organic nitrogen contents in biopolymer and HS characterized by LC-OCD-OND had strong correlations with N-DBPFPs from AOM and NOM, indicating that LC-OCD-OND quantitative analysis could improve the prediction accuracy of the DBP formation than bulk parameters during NOM and AOM chlorination.

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
The internal source pollution of sediment is the main factor leading to the repetition of black-odorous river channels. In order to prevent this situation, a river channel in the Binhu District of Wuxi City was used as an experimental site. In-situ CaO2 combined with a biochar covering technology was used to repair the black odorous river sediment in this channel. The effects of this technology on the quality of mud water, sedimentary volatile sulfide (AVS) and phosphorus forms, microorganisms, and restoration of black odorous sediment were investigated. The results showed that CaO2 combined with biochar coverage could significantly increase the dissolved oxygen (DO) concentration and redox potential (ORP) of the muddy water system. The DO concentration and ORP in the overlying water were maintained above 2 mg·L-1 and 50 mV, respectively. The removal rates of interstitial water ammonia-nitrogen (NH4+-N), chemical oxygen demand (COD), and total phosphorus (TP) reached 43.40%, 41.18%, and 50.97%, respectively. The removal rate of AVS in the sediment reached 37.03%. The high-throughput sequencing showed that the relative abundance of anaerobic microorganisms in the sediment was significantly reduced, and that nitrogen and sulfur removal microorganisms appeared (e.g., Thermomonas, Dechloromonas, Proteus hauser, Desulfomicrobium, and Thiobacillus). Phosphorus in the sediment was converted into Fe/Al-P and Ca-P. Therefore, in-situ CaO2 combined with biochar coverage had a good repairing effect on black odorous sediment.

Abstract
Adenosine triphosphate (ATP) biomolecules play critial roles in the biomineralization process during the formation of amorphous calcium phosphate composites (ACPC), and ACPC is an important drug carrier due to its significant advantages of biocompatibility and biodegradability. Hence, studying the behavior of ACPC nanodrug carriers is crucial to investigate the structural regulation of biomimetic minerals and calcium phosphate (CaP)-based drug delivery systems. However, it is difficult to probe these interactions using traditional characterization methods. In this paper, XANES analysis together with STXM successfully provided a method to reveal the interaction of ATP and drug molecules with individual mesoporous ACPC. We found that the adenosine and phosphate groups of ATP biomolecules coordinated with Ca2+ and played critical roles in the formation of ACPC; drug molecules with the -COOH groups were linked to Ca2+via carboxylic acid groups primarily by electrostatic interactions, and the N-containing ring structures within the drug molecules also coordinated with Ca2+.

Abstract
Background Propofol is the most widely used intravenous sedative-hypnotic anesthetic in clinical practice. However, many serious side effects have been related to its lipid emulsion formulation. The pro-drug design approach was used to develop the water-soluble propofol, which could effectively resolve the limitations associated with the lipid emulsion formulation. Thus, the new water-soluble pro-drug of propofol, HX0969W, was designed and synthesized. The objective of this study was to conduct preclinical pharmacological studies on this novel water-soluble pro-drug of propofol. Methods The assessment of the loss of the righting reflex (LoRR) was used for the pharmacodynamic study, and liquid chromatography-tandem mass spectrometry and high-performance liquid chromatography- fluorescence were used for the pharmacokinetic study. Results The potency of HX0969W (ED50 [95% CI], 46.49 [43.89–49.29] mg/kg) was similar to that of fospropofol disodium (43.66 [43.57–43.75] mg/kg), but was lower than that of propofol (4.82 [4.8–14.82] mg/kg). Administered with a dose of 2-fold ED50, propofol required a shorter time to cause LoRR than that of HX0969W and fospropofol. However, the LoRR duration was significantly longer in response to the administration of HX0969W and fospropofol disodium than that caused by propofol. In the pharmacokinetic study, the Cmax of fospropofol was higher than that of HX0969W. HX0969W had a shorter mean residual time and a rapid clearance rate than that of fospropofol disodium. There was no significant difference between the Tmax of the propofol whether it was released by HX0969W or fospropofol disodium; the Cmax of propofol released by HX0969W was similar to that of propofol, which was higher than the propofol released by fospropofol disodium.

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
Neuromuscular blockers (NMBs) selectively block neuromuscular transmission at the N2-nicotinic receptor on motor neurons to paralyze skeletal muscles, and are mainly used to facilitate tracheal intubation and surgical procedures. Rapid reversal is necessary in clinical practice to avoid profound block and reduce recovery time. Adamgammadex sodium is a modified γ-cyclodextrin derivative consisting of a lipophilic core and a hydrophilic outer end that forms an inactive tight inclusion complex with free molecules of rocuronium and vecuronium. In preclinical study, adamgammadex produced a concentration-dependent reversion effect of neuromuscular blockade induced by rocuronium in beagle dogs. Furthermore, adamgammadex had a less potential side effects than sugammadex and other clinical used neuromuscular block antagonists. In this study, the objective was to assess the safety, tolerability, and pharmacokinetics of single intravenous injection of adamgammadex in healthy volunteers. Approved by the China Food and Drug Administration, 52 healthy volunteers (half male and half female) were enrolled in this single-center, randomized, double-blind placebo-controlled study. No serious adverse effects were happened in this study. The overall frequency of adverse effects in adamgammadex was similar for that in placebo, and there was no specific adverse effect in adamgammadex. All of the volunteers bearing the adverse effects were recovered to normal without any treatment or intervention. In pharmacokinetic study, the value of half-time, Tmax, and clearance were not changed significantly, and the Cmax and AUC0-∞ increased with a similar ratio of the escalating doses. For dose proportionality analysis of adamgammadex, the estimate of slope was close to 1, and it was not significantly different from 1 after doses (AUC0-∞, 0.9965 [90%CI, 0.9468, 1.046]; Cmax, 0.9462 [90%CI, 0.8800, 1.012]). Therefore, adamgammadex exposure in plasma increased in a dose- proportional manner. The urinary route is a significant excretory pathway for adamgammadex, and it is mostly completed at 8 h. All the results in this study showed that adamgammadex may be a novel safe neuromuscular blockade reversal agent .

Abstract
Pennisetum sinese is a good forage grass with high biomass production and crude proteins. However, little is known about the endophytic fungi diversity of P. sinese, which might play an important role in the plant’s growth and biomass production. Here, we used high throughput sequencing of the Internal Transcribed Spacer (ITS) sequences based on primers ITS5-1737 and ITS2-2043R to investigate the endophytic fungi diversity of P. sinese roots at the maturity stage, as collected from four provinces (Shaanxi province, SX; Fujian province, FJ; the Xinjiang Uyghur autonomous prefecture, XJ and Inner Mongolia, including sand (NS) and saline-alkali land (NY), China). The ITS sequences were processed using QIIME and R software. A total of 374,875 effective tags were obtained, and 708 operational taxonomic units (OTUs) were yielded with 97% identity in the five samples. Ascomycota and Basidiomycota were the two dominant phyla in the five samples, and the genera Khuskia and Heydenia were the most abundant in the FJ and XJ samples, respectively, while the most abundant tags in the other three samples could not be annotated at the genus level. In addition, our study revealed that the FJ sample possessed the highest OTU numbers (242) and the NS sample had the lowest (86). Moreover, only 22 OTUs were present in all samples simultaneously. The beta diversity analysis suggested a division of two endophytic fungi groups: the FJ sample from the south of China and the other four samples from north or northwest China. Correlation analysis between the environmental factors and endophytic fungi at the class level revealed that Sordariomycetes and Pucciniomycetes had extremely significant positive correlations with the total carbon, annual average precipitation, and annual average temperature, while Leotiomycetes showed an extremely significant negative correlation with quick acting potassium. The results revealed significant differences in the root endophytic fungi diversity of P. sinese in different provinces and might be useful for growth promotion and biomass production in the future.

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
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
Water movement over and through soil is largely driven by topography and soil management across landscapes. This research tested the hypothesis that the water movement determines the potential for P and Ca redistribution and pH variance across landscapes. This hypothesis was evaluated by using digital elevation model-derived terrain attributes in fields after 55 yr of broiler litter applications on pastures in Smith County, Mississippi. Results show that soils receiving broiler litter had mean Mehlich-3 P levels of 1221.8 mg kg at 0- to 15-cm depth and 618.6 mg kg at 15- to 30-cm depth, and Ca with mean values of 768.3 and 645.0 mg kg at 0- to 15-cm and 15- to 30-cm soil depths, respectively. Across fields, soils in areas of predicted convergent flow contained higher P, Ca, and lower pH values in the upper 0 to 15 cm, suggesting contributions via surface overland flow from areas with higher elevation and lower slope gradient. On the other hand, soils in areas with lesser slope and higher elevation also contained high levels of P, Ca, and pH for the subsurface soil depth, suggesting that vertical flow of water on this landscape is a mechanism for movement of P and Ca deeper in the profile. The incorporation of topographic characteristics across fields offers promising results that may be incorporated into improved P indices and management, making them more robust indicators of P mobilization to waterways.

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
Sphingolipids are a class of novel lipid bioregulatory molecules that play important roles in regulating cell growth, differentiation, proliferation, and apoptosis. Sphingolipid metabolism disorders could induce the development of various diseases including hepatocellular carcinoma (HCC). With the development of lipidomics, it has been demonstrated that sphingolipids play an increasingly essential role in the occurrence, development, and outcome of HCC. Studies have shown that sphingolipids can be used as a new biomarker for the diagnosis of HCC, and regulation of the sphingolipid metabolism pathway may be a potential target for the treatment of HCC. This paper reviews the current progress in research of sphingolipids with regard to their classification, metabolic pathways, role in the development of HCC, and the possibility as a target for diagnosis and treatment of HCC.

Abstract
In vivo mineralization is a multistep process involving mineral-protein complexes and various metastable compounds in vertebrates. In this complex process, the minerals produced in the mitochondrial matrix play a critical role in initiating extracellular mineralization. However, the functional mechanisms of the mitochondrial minerals are still a mystery. Herein, an in vitro enzymatic reaction strategy is reported for the generation of biomimic amorphous calcium phosphate (EACP) nanominerals by an alkaline phosphatase (ALP)-catalyzed hydrolysis of adenosine triphosphate (ATP) in a weakly alkalescent aqueous condition (pH 8.0-8.5), which is partially similar to the mitochondrial environment. Significantly, the EACP nanomineral obviously promotes autophagy and osteogenic differentiation of human bone marrow-derived mesenchymal stem cells by activating an AMPK related pathway, and displays a high performance in promoting bone regeneration. These results provide in vitro evidence for the effect of ATP on the formation and stabilization of the mineral in the mineralization process, demonstrating a potential strategy for the preparation of the biomimic mineral for treating bone related diseases.

Abstract
The development of multifunctional dental-restorative biomaterials with antibacterial activity and remineralization effect for damaged tooth repair is urgent since dental caries is still one of the most common tooth diseases in human beings. Herein, we report a facile strategy for the synthesis of gluey silver-calcium phosphate (GSCP) composites using the rapid microwave-assisted solvothermal method. The as-prepared GSCP composite is an organic-inorganic hybrid, and Ag+ ions display a significant influence on the formation of GSCP by interacting with adenosine triphosphate biomolecules. The as-prepared GSCP composite shows good antibacterial properties, in addition, it exhibits a great effect on sheltering dentinal canaliculi and improving the remineralization of dentine in the simulated saliva. The as-prepared GSCP composite is promising for various applications such as oral healthcare, especially, remineralization of dentine, and antibacterial applications.

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
Mother-to-child transmission of hepatitis B virus (HBV) is one of major public health issues. Difference is found on effect of preventions of mother to child transmission of HBV such as Hepatitis B vaccine, Hepatitis B immunoglobulin and antiretroviral drugs. Based on the risks of hepatitis B virus on children, influencing factors and interventions of HBV mother-to-child transmission were explored to improve prevention mother-to-child transmission of hepatitis B and to search appropriate strategies reducing mother-to-child transmission of HBV.

Abstract
With the growing popularity of electrical communication equipment, high-performance electromagnetic interference (EMI) shielding materials are widely used to deal with radiation pollution. However, the large thickness and poor mechanical properties of many EMI shielding materials usually limit their applications. In this study, ultrathin and highly flexible Ti3C2T x (d-Ti3C2T x, MXene)/cellulose nanofiber (CNF) composite paper with a nacre-like lamellar structure is fabricated via a vacuum-filtration-induced self-assembly process. By the interaction between one-dimensional (1D) CNFs and two-dimensional (2D) d-Ti3C2T x MXene, the binary strengthening and toughening of the nacre-like d-Ti3C2T x/CNF composite paper has been successfully achieved, leading to high tensile strength (up to 135.4 MPa) and fracture strain (up to 16.7%), as well as excellent folding endurance (up to 14 260 times). Moreover, the d-Ti3C2T x/CNF composite paper exhibits high electrical conductivity (up to 739.4 S m-1) and excellent specific EMI shielding efficiency (up to 2647 dB cm2 g-1) at an ultrathin thickness (minimum thickness 47 μm). The nacre-inspired strategy in this study offers a promising approach for the design and preparation of the strong integrated and flexible MXene/CNF composite paper, which may be applied in various fields such as flexible wearable devices, weapon equipment, and robot joints.

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
Chronic hepatitis C virus (HCV) infection is a serious public health problem worldwide. China, as the country with the largest number of HCV infections in the world, plays a significant role in eliminating hepatitis C. Due to different financial situations and education background, hepatitis C patients take different actions for their disease treatment and management. Therefore, antiviral treatment status should be attached great importance to learn the medical demand of patients. A nationwide, multicenter survey was conducted from July 2015 to June 2016. Of 1798 inpatients and outpatients with chronic HCV from 56 hospitals participated in the survey. Each patient completed the questionnaire with questions about his/her antiviral therapy status, perception of treatment barriers, and expectations for future treatment. In total 1622 patients, including 1241 with chronic hepatitis C, 344 with cirrhosis, and 37 patients with hepatocellular carcinoma, fulfilled data collection requirements and finally were included in analysis. Overall, up to 30.7% of the patients had not or currently does not intend to receive antiviral therapy. The main reason was expecting more potent and well-tolerance medication (31.5%), followed by the fear of interferon related side effects (27.5%). Multiple regression analysis showed that the patient's annual income, the severity of HCV, and comorbidity were independent predictors of not receiving antiviral therapy. The whole patients were expecting more potent and well tolerance medication available soon. In summary, Peg-IFN/RBV treatment regimen cannot meet the need of patients well, and safe and efficient direct-acting antivirals are urgently needed in mainland China.
