Nannan LIU, Mei MA, Yiping XU, Jinmiao ZHA, Kaifeng RAO, Zijian WANG

《环境科学与工程前沿（英文）》 2013年 第7卷 第1期   页码 77-84 doi: 10.1007/s11783-012-0466-z

摘要： 2,4,6-trichlorophenol (2,4,6-TCP) is a widespread probable human carcinogen and has been proven to have genotoxicity in assays. However, little genotoxicity information and no micronuclei induction data for 2,4,6-TCP is available from tests, especially for sex-specific differences. Following a preliminary test, a piscine peripheral erythrocyte micronucleus assay was conducted on medaka ( ) after a 28-day exposure to 2,4,6-TCP. In the present study, the mean micronuclei (MNC) frequencies of all of the groups increased in a dose-dependent manner, which indicated the potential genotoxicity of 2,4,6-TCP. Moreover, males were found to be more susceptible compared with females after a 28-day exposure to 2,4,6-TCP in all of the dosed groups above 10 μg·L . This is the first report on the potential of micronuclei induction and a sex-susceptible effect in the peripheral erythrocytes of mature fish after 2,4,6-TCP exposure.

Xiaoxia LU, Weikun HU, Shengdao XIONG, Guopeng XU, Fen LAN

《医学前沿（英文）》 2009年 第3卷 第2期   页码 187-190 doi: 10.1007/s11684-009-0033-6

摘要： The study aimed to detect the expression of the Th1-specific cell surface protein T cell Ig and mucin domain-containing molecule-3 (Tim-3) mRNA in peripheral blood lymphocytes isolated from asthmatic patients and to examine the correlation among Tim-3 mRNA, interleukin-4 (IL-4), interferon-γ (IFN-γ) level, and FEV1/FVC (force expiratory volume in one second/forced vital capacity) to explore the role of Tim-3 in the development and progression of asthmatic inflammation. Tim-3 mRNA expression was detected by reverse transcription polymerase chain reaction (RT-PCR). The IL-4 and IFN-γ levels were determined by using enzyme-linked immunosorbent assay (ELISA). The correlation among Tim-3 mRNA, IL-4, IFN-γ level, and pulmonary ventilatory capacity was analyzed. The expression of Tim-3 mRNA in patients with acute asthma exacerbation was 0.39±0.06, significantly higher than that in patients at the remission stage and controls (0.18±0.05 and 0.07±0.03, <0.05). The level of IL-4 in patients with acute asthma exacerbation was 68.42±10.54, significantly higher than that in the patients at the remission stage and controls (41.83±9.37 and 32.75±8.16, <0.05). The level of IL-4 in patients in remission was significantly higher than that in controls ( <0.05). The level of IFN-γ in patients with acute asthma exacerbation was 65.74±7.85, significantly lower than that in patients in remission and the control group (120.84±11.62 and 139.65±13.47, <0.05). The level of IFN-γ in patients in asthma remission was significantly lower than that in controls ( <0.05). Tim-3 mRNA expression was positively correlated with the level of IL-4 ( =0.68, <0.05) and negatively with the level of IFN-γ and pulmonary ventilatory capacity ( =-0.85, =-0.76, both <0.01). The increased expression of Tim-3 mRNA in peripheral blood lymphocytes might be involved in the development and progression of asthmatic inflammation.

SUN Ledong, SUN Jing, ZENG Kang, MENG Fanyi, DIAO Youtao, XU Dan, HUANG Liang, ZHAO Jie, Liu Qifa

《医学前沿（英文）》 2008年 第2卷 第2期   页码 191-194 doi: 10.1007/s11684-008-0036-8

摘要： The aim of this study is to explore the effectiveness of autologous peripheral hematopoietic stem-cell transplantation in the treatment of refractory pemphigus. A 35-year-old male patient presented with a 4-year history of recurrent bullae on his trunk and extremities. The diagnosis of pemphigus was made on the basis of the clinical, histologic and immunofluorescence findings. The patient had shown resistance to conventional therapy with glucocorticoid and immunosuppressive agents. Two months before admission, he complained of hip joint pain. X-ray and CT scan revealed aseptic necrosis of the femoral head. Stem-cell mobilization was achieved by treatment with cyclophosphamide, granulocyte colony-stimulating factor (G-CSF) and rituximab. Peripheral blood stem cells were collected via leukapheresis and cryopreserved for later use. Immunoablation was accomplished by using cyclophosphamide (200 mg/kg; divided into 50 mg/kg on days -5, -4, -3, and -2), antithymocyte globulin (ATG; 10 mg/kg; divided into 2.5 mg/kg on days -6, -5, -4, and -3), and rituximab (1200 mg/d; divided into 600 mg/d on days 0 and 7). Autologous peripheral hematopoietic stem cell transplantation was followed by reconstitution of the immune system which was monitored by flow cytometry. The glucocorticoid was withdrawn immediately after transplantation. The pemphigus titer turned negative 6 weeks after transplantation and remained negative. The patient was in complete drug-free remission with no evidence of residual clinical or serological activity of pemphigus during 1 year of follow-up. The patient’s response suggests that autologous peripheral hematopoietic stem cell transplantation may be a potential “cure” for refractory pemphigus. However, further studies are needed to evaluate the risk-benefit ratio of this approach in patients with pemphigus showing resistance to conventional therapy.

Transcriptomic basis of neutrophil ratio variation induced by poly I:C stimulation in porcine peripheral

Haiyan WANG, Qiaoxia ZHANG, Lilin YIN, Xiangdong LIU, Shuhong ZHAO, Mengjin ZHU, Changchun LI

《农业科学与工程前沿（英文）》 2017年 第4卷 第3期   页码 342-352 doi: 10.15302/J-FASE-2017162

摘要： Neutrophils are vital components of defense mechanisms against invading pathogens and are closely linked with the individual antiviral capacity of pigs and other mammals. Neutrophilia is a well-known clinical characteristic of viral and bacterial infections. Using Affymetrix porcine genome microarrays, we investigated the gene expression profiles associated with neutrophil variation in porcine peripheral blood before and after polyriboinosinic-polyribocytidylic acid stimulation. Transcriptomic analysis showed 796 differentially expressed genes (DEGs) in extreme response (ER) pigs and 192 DEGs in moderate response (MR) pigs. Most DEGs were related to immune responses, included , , , , , , , and . Gene ontology analysis indicated that the DEGs of both ER and MR pigs were involved in common biological processes, such as cell proliferation, growth regulation, immune response, inflammatory response and cell activation. The ER and MR groups also showed differences in DEGs involved in biological processes. DEGs involved in cell division and cell cycle were specifically found in the ER pigs, whereas DEGs involved in cell migration were specifically found in the MR pigs. The study provides a basic understanding of the molecular basis for the antiviral capacity of pigs and other mammals.

《医学前沿（英文）》 2017年 第11卷 第4期   页码 548-553 doi: 10.1007/s11684-017-0597-5

摘要：

This study determined the effect of hepatitis B virus (HBV) replication in peripheral blood mononuclear cell (PBMC) from HBsAg-positive mothers on HBV intrauterine transmission. A total of 150 HBsAg-positive mothers and their neonates were recruited in this study. Within 24 h after birth, HBV serological markers, serum HBV DNA, PBMC HBV relaxed circular DNA (rcDNA), and covalently closed circular DNA (cccDNA) were measured in the HBsAg-positive mothers and their neonates before passive-active immune prophylaxis. The relationship between HBV replication in PBMC and HBV intrauterine transmission was examined through Chi-square test and logistic regression. The rate of HBV intrauterine transmission was 8.00% (12/150) in the 150 neonates born to HBsAg-positive mothers. The positivities of PBMC HBV rcDNA and cccDNA in the HBsAg-positive mothers were 36.67% (55/150) and 10% (15/150), respectively. Maternal PBMC HBV cccDNA was a risk factor of HBV intrauterine transmission (OR= 6.003, 95% CI: 1.249–28.855). Maternal serum HBeAg was a risk factor of PBMC HBV rcDNA (OR= 3.896, 95% CI: 1.929–7.876) and PBMC HBV cccDNA (OR= 3.74, 95% CI: 1.186–11.793) in the HBsAg-positive mothers. Administration of hepatitis B immune globulin was a protective factor of PBMC HBV cccDNA (OR= 0.312, 95% CI: 0.102–0.954) during pregnancy. The positivity of PBMC HBV rcDNA was related to that of cccDNA in the HBsAg-positive mothers (c2=5.087, P= 0.024). This study suggests that PBMC is a reservoir of HBV and an extrahepatic site for virus replication and plays a critical role in HBV intrauterine transmission.

Fludarabine and intravenous busulfan conditioning with post-transplantation cyclophosphamide for allogeneic peripheral

Ling Wang, Lining Wang, Xing Fan, Wei Tang, Jiong Hu

《医学前沿（英文）》 2021年 第15卷 第1期   页码 108-115 doi: 10.1007/s11684-019-0730-8

摘要： Post-transplantation cyclophosphamide (PT-Cy) alone or in combination with other immunosuppressive drugs has emerged as a promising strategy in the setting of allogeneic hematopoietic stem cell transplantation. Improved survival rate was reported in lymphoid malignancies following PT-Cy strategy compared with myeloid disease in non-myeloablative bone marrow transplant setting. Thus, we aimed to evaluate the safety and efficacy of PT-Cy combined with cyclosporine as graft-versus-host disease (GVHD) prophylaxis after myeloablative conditioning and T cell-replete peripheral stem cell transplantation in lymphoid malignancies. This single-arm phase II clinical trial (NCT01435447) involving 31 adult patients was conducted from January 2013 to June 2018. The donor-type neutrophil engraftment rate was 100%, and the overall incidence of grade II to IV and grade III to IV acute GVHD was 39% and 24%, respectively. The cumulative incidence rates of chronic GVHD (35%), including moderate to severe forms (10%), were reduced compared with those of the historical group ( =0.03 and =0.04, respectively). With a median follow-up of 18 months, the estimated 2-year overall and event-free survival was 64.8% (95% confidence interval: 47.8%–86.7%) and 58.4% (95% CI: 41.9%–81.7%), respectively. The 2-year cumulative incidence rate of relapse was 19.5% (95% CI: 9.0%–35.8%), whereas the non-relapse mortality rate was 21.8% (95% CI: 11.3%–38.1%). These results demonstrated the feasibility of PT-Cy as GVHD prophylaxis in this clinical setting. This strategy could significantly reduce the incidence of chronic GVHD and its moderate to severe forms but not of acute GVHD and results in similar survival outcomes compared with the historical group. A prospective study with additional patients is warranted to confirm the role of PT-Cy in lymphoid malignancy.

《医学前沿（英文）》 2010年 第4卷 第2期   页码 220-224 doi: 10.1007/s11684-010-0025-6

摘要： This study examined the inhibitory effect of triptolid (TP) on tumor necrosis factor-α (TNF-α) secreted from peripheral blood monocular cells (PBMCs) and the association of the inhibitory effect with TNF-α-308 gene polymorphisms in rheumatoid arthritis (RA) patients. Gene polymorphism at A-G site 308 in the promoter region of TNF-α gene was detected in 42 RA patients by using allele specific polymerase chain reaction (AS-PCR) assay. PBMCs were harvested from these patients and treated first with lipopolysaccharides (LPS) and then with different doses of TP (1, 5.4 and 15 ng/mL). The TNF-α level in the supernatants was measured by enzyme-linked immunosorbent assay (ELISA). The results showed that TNF-α level in the supernatants of TP (1 ng/mL)-treated PBMCs was decreased by 3.80% and 4.91%, respectively, in the patients with AA and AG genotypes, when compared with those treated with LPS alone (>0.05). Moreover, the TNF-α level in the patients with GG genotype was reduced by 20.74% (<0.05). When PBMCs were treated with TP at 5.4 ng/mL, TNF-α levels in the patients with AA, AG, and GG genotypes were decreased by 20.42%, 34.73%, and 41.69%, respectively (<0.05). The TNF-α level was slightly higher in the PBMCs treated with 15 ng/mL of TP than those in the two TP groups in the patients carrying AA, AG, and GG genotypes (>0.05). It was concluded that gene polymorphism at TNF-α-308 sites may relate to the secretion of TNF-α in RA patients. TP has different inhibitory effects on the secretion of TNF-α in the patients harboring different genotypes, which may be one of the reasons for individual variation in response to TP.

Photoinduced dichroism and surface-relief-gratings of hyperbranched azo polymers synthesized by azo-coupling reaction

CHE Pengchao, HE Yaning, WANG Xiaogong

《化学科学与工程前沿（英文）》 2007年 第1卷 第4期   页码 360-364 doi: 10.1007/s11705-007-0065-x

摘要： This article reports the synthesis and photoresponsive properties of a hyperbranched azo polymer containing electron donor-acceptor type azo chromophores both in backbone and peripheral positions. For the synthesis, a hyperbranched azo precursor polymer was synthesized by step-growth polymerization of an AB monomer, bis[2-(-ethylanilino)ethyl] 5-aminoisophthalate, through azo-coupling reaction. The hyperbranched precursor polymer was then reacted with the diazonium salt from 4-cyanoaniline to introduce donor-acceptor azo chromophores in the peripheral groups. The resulting azo polymers were characterized by the spectroscopic methods and thermal analysis. The photoinduced dichroism of the hyperbranched polymer was studied and its orientation order parameter was estimated to be 0.063. Thin films of the hyperbranched azo polymers were used to fabricate surface-relief-gratings (SRGs) by exposing them to an interference pattern of Ar laser beam at modest intensities (150 mW/cm). The azo chromophores introduced by post-azo-coupling reaction at the para-positions of the peripheral azobenzenes shows a significant effect on the SRG inscription rate. The hyperbranched azo polymers can potentially be used for applications such as reversible optical data storage, photoswitch, sensors, and other photo-driven devices.

Mechanical performance analysis and stiffness test of a new type of suspension bridge

《结构与土木工程前沿（英文）》 2021年 第15卷 第5期   页码 1160-1180 doi: 10.1007/s11709-021-0760-6

摘要： A new type of suspension bridge is proposed based on the gravity stiffness principle. Compared with a conventional suspension bridge, the proposed bridge adds rigid webs and cross braces. The rigid webs connect the main cable and main girder to form a truss that can improve the bending stiffness of the bridge. The cross braces connect the main cables to form a closed space truss structure that can improve the torsional stiffness of the bridge. The rigid webs and cross braces are installed after the construction of a conventional suspension bridge is completed to resist different loads with different structural forms. A new type of railway suspension bridge with a span of 340 m and a highway suspension bridge with a span of 1020 m were designed and analysed using the finite element method. The stress, deflection of the girders, unbalanced forces of the main towers, and natural frequencies were compared with those of conventional suspension bridges. A stiffness test was carried out on the new type of suspension bridge with a small span, and the results were compared with those for a conventional bridge. The results showed that the new suspension bridge had a better performance than the conventional suspension bridge.

《结构与土木工程前沿（英文）》 2015年 第9卷 第4期   页码 397-404 doi: 10.1007/s11709-015-0321-y

摘要： Composite materials reinforced with carbon nanotubes were mechanical tested using Arcan test rig under Mode-I, Mode-II and mixed mode loading conditions to obtain their fracture properties. The butterfly composite specimens were fabricated with 0.02, 0.05 and 0.1 wt % CNTs. The polyester/CNT composite was fabricated using VRTM (Vacuum Resin Transfer Molding) where the CNTs were first functionalised to reach an optimum properties. Arcan test rig was designed and fabricated to work with the Shimadzu testing machine. The results show that the functionalised CNTs have improved the fracture behavior by acting as bridge between the cracked face. In addition, the fracture properties were not improved for the higher weight fraction of 0.1 wt% CNTs.

Tian TIAN, Jianjun TANG, Wei GUO, Mu PAN

《能源前沿（英文）》 2017年 第11卷 第3期   页码 326-333 doi: 10.1007/s11708-017-0489-z

摘要： In this paper, a novel accelerated test method was proposed to analyze the durability of MEA, considering the actual operation of the fuel cell vehicle. The proposed method includes 7 working conditions: open circuit voltage (OCV), idling, rated output, overload, idling-rated cycle, idling-overload cycle, and OCV-idling cycle. The experimental results indicate that the proposed method can effectively destroy the MEA in a short time (165 h). Moreover, the degradation mechanism of MEA was analyzed by measuring the polarization curve, CV, SEM and TEM. This paper may provide a new research direction for improving the durability of fuel cell.

Application of metal magnetic memory test in failure analysis and safety evaluation of vessels

Yiliang ZHANG, Song YANG, Xuedong XU

《机械工程前沿（英文）》 2009年 第4卷 第1期   页码 40-48 doi: 10.1007/s11465-009-0003-3

摘要： Metal magnetic memory test (MMMT), which is a new subject in the field of nondestructive examination, can determine regions of stress concentration by testing the distribution of the magnetic field of metal structures so as to effectively diagnose premature defects. MMMT and other test methods are applied in the study to put a propylene purifier of a temperature-jump accident and a leaked ammonia vessel through safety evaluation. Results are as follows: The margin of safety declines after the purifier is overburnt; several stress concentrations are observed within the overburnt area and the level of stress concentration rises after one-month operation; and overpressure operation of the purifier must be strictly avoided and carefully monitored during later operation. Cracks are observed on the ammonia vessel after one year’s service. Extremely high residual stress is the primary cause of cracks. After four years in service, the residual stresses existing in the area of the base metal and weld zone are still greater than 0.5 , which results in numerous cracks due to stress corrosion. From the MMMT result of the ammonia vessel’s defects, it can be seen that the derivative of magnetic density (d p/d ) is an important reference variable. Within the 31 leakage points, 67.7% of them whose dHp/dx values are more than 10, and 96.8% of them whose dHp/dx values are more than 8.
