Abstract
Objective: To explore and compare the reference ranges of four coagulation tests in normal pregnant women during early and late pregnancy and the influence of age. Methods: Values of four coagulation tests from 4 974 pregnant women, who gave single birth at Peking University First Hospital, Obstetrics and Gynecology Hospital of Fudan University, West China Second University Hospital, Peking University Third Hospital and Shengjing Hospital of China Medical University from February 2017 to July 2020, were measured and analyzed in this study, including prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib) and thrombin time (TT). The four normal reference ranges of coagulation during early and late pregnancy phases were expressed as P2.5-P97.5. The difference of two pregnancy phases was compared by non-parametric test of two related samples. And the difference between pregnant women of advanced and non-advanced age in the same pregnancy phase was compared by independent sample non-parametric test. Chi-square test was used to compare the incidence of pregnancy complications in different coagulation reference ranges. Results: The reference ranges of PT of normal pregnant women's early and late pregnancy were 10.0-13.9 s and 9.6-12.3 s, the reference ranges of APTT were 22.6-35.3 s and 22.4-30.9 s, the reference ranges of Fib were 2.4-5.0 g/L and 3.0-5.7 g/L, the reference ranges of TT were 12.0-19.0 s and 11.5-18.4 s. Compared with early pregnancy, PT, APTT and TT shortened significantly, while the Fib significantly increased in late pregnancy (all P<0.001). PT, APTT and TT of advanced and non-advanced age pregnant women were significantly different (all P<0.01). Compared with the ranges of non-pregnant population, more pregnant women were included in the normal pregnant reference ranges of PT in early pregnancy and APTT in the early and late pregnancy, while the incidence of pregnancy complications had no significant differences (all P>0.05). The incidence of fetal distress was higher and the incidence of preterm birth was lower in the reference range of PT in late pregnancy. The incidence of gestational diabetes mellitus was higher in the early and late gestational Fib reference ranges, and the incidence of hypertensive disorders in pregnancy was higher in the late gestational Fib reference range (all P<0.05). Conclusions: The coagulation function of pregnant women increases significantly with the growth of pregnancy, and there is a significant difference between advanced significantly and non-advanced age pregnant women. The recommended ranges of normal pregnant women's early and late pregnancy PT are 10.0-13.9 s and 9.6-12.3 s, the recommended ranges of APTT are 22.6-35.3 s and 22.4-30.9 s, the recommended ranges of TT are 12.0-19.0 s and 11.5-18.4 s. The appropriate ranges of normal pregnant women's early and late pregnancy Fib still need further exploration.

Abstract
In this study, we added ZrO₂ and Y₂O₃ to stabilize the anatase TiO₂ phase at higher temperatures. Composite mesoporous TiO₂/ZrO₂/Y₂O₃ (TZY) oxides were prepared by a sol-gel method, and triblockcopolymer P123 and PEG was used as templates. The properties of the synthesized materials were characterized using X-Ray diffraction (XRD), Raman scattering, N₂ adsorption/desorption, and UV-Visible spectrophotometry (UV-Vis) methods et al. The samples prepared using P123 and PEG as double-template exhibited smaller particles and a higher specific surface area than the samples prepared using P123 and PEG as single-template. Furthermore, crystal phase transition from anatase to rutile occurred later in the case of the double-template method. After introducing ZrO ₂and Y₂O₃, the crystal phase transition and the growth of crystallites were severely suppressed. The results indicated that the RhB degradation efficiency for the double-template method was 99.24%, while the RhB degradation efficiency with TZY/P123 and TZY/PEG samples was 97.43 and 98.18%, respectively.

Abstract
Simiao Yong'an Decoction is composed of Lonicerae Japonicae Flos, Scrophulariae Radix, Angelicae Sinensis Radix, Glycyrrhizae Radix et Rhizome, which was chosen as one of the 100 classic prescriptions in Catalogue of Ancient Classics Prescription(the first batch). Through tracing to the source, It was found that the Simiao Yong'an Decoction(but not named) originated from the Shi Shi Mi Lu, and was later cited by books such as Ancient and Modern Book Integration-Full Record of Medical Department and New Edition of Useful Prescriptions. Literature shows that this prescription was not named until first reported in the Effect of Traditional Chinese Medicine on Arterial Embolism Gangrene in 1956 by a journalist LYU Min. This article recorded that SHIJIA Baoshan, a monk from Hebei Province, used self-named "Simiao Yong'an Decoction" to treat local arterial embolic gangrene. After comparison, there was two difference between ancient books and SHIJIA Baoshan's records. Firstly, according to ancient books, the composition and dosage of Simiao Yong'an Decoction is Lonicerae Japonicae Flos 90 g, Scrophulariae Radix 90 g, Angelicae Sinensis Radix 60 g, Glycyrrhizae Radix et Rhizome 30 g", and the ratio is 3∶3∶2∶1. By SHIJIA Baoshan's record, the composition and dosage are: Lonicerae Japonicae Flos 66 g, Scrophulariae Radix 132 g, Angelicae Sinensis Radix 99 g, Glycyrrhizae Radix et Rhizome 33 g, and the ratio changed to 2∶4∶3∶1. Secondly, ancient books show that patients can be healed after taking seven or ten days of the previous prescription, however, it would take 3 or 4 months, even 7 months in SHIJIA Baoshan's records. It can be considered that the previous prescription should be used at the beginning of gangrene, while the modified Simiao Yong'an Decoction by SHIJIA Baoshan is widely used in the middle and late stages of gangrene, even the critical condition, that is the reason for longer treatment and larger dosage. Nowadays, Simiao Yong'an Decoction is not limited to the treatment of gangrene and bulla in clinic. Relevant studies have confirmed that Simiao Yong'an Decoction has the effects such as anti-inflammatory, plaque stabilization, lipid-lowering, vascular protection, improvement of hemorheology, anticoagulation, inhibition of thrombosis and fibrinolysis, etc. In the follow-up, we should carry out the analysis of the compatibility of this four medicines, and redefine the scope of its clinical application under the theory of traditional Chinese medicine.

Abstract
Importance The outcome of older patients with acute myeloid leukemia (AML) remains unsatisfactory. Recent studies have shown that HLA-mismatched microtransplant could improve outcomes in such patients. Objective To evaluate outcomes in different age groups among older patients with newly diagnosed AML who receive HLA-mismatched microtransplant. Design, Setting, and Participants This multicenter clinical study included 185 patients with de novo AML at 12 centers in China, the United States, and Spain in the Microtransplantation Interest Group. Patients were divided into the following 4 age groups: 60 to 64 years, 65 to 69 years, 70 to 74 years, and 75 to 85 years. The study period was May 1, 2006, to July 31, 2015. Exposures Induction chemotherapy and postremission therapy with cytarabine hydrochloride with or without anthracycline, followed by highly HLA-mismatched related or fully mismatched unrelated donor cell infusion. No graft-vs-host disease prophylaxis was used. Main Outcomes and Measures The primary end point of the study was to evaluate the complete remission rates, leukemia-free survival, and overall survival in different age groups. Additional end points of the study included hematopoietic recovery, graft-vs-host disease, relapse rate, nonrelapse mortality, and other treatment-related toxicities. Results Among 185 patients, the median age was 67 years (range, 60-85 years), and 75 (40.5%) were female. The denominators in adjusted percentages in overall survival, leukemia-free survival, relapse, and nonrelapse mortality are not the sample proportions of observations. The overall complete remission rate was not significantly different among the 4 age groups (75.4% [52 of 69], 70.2% [33 of 47], 79.1% [34 of 43], and 73.1% [19 of 26). The 1-year overall survival rates were 87.7%, 85.8%, and 77.8% in the first 3 age groups, which were much higher than the rate in the fourth age group (51.7%) (P = .004, P = .008, and P = .04, respectively). The 2-year overall survival rates were 63.7% and 66.8% in the first 2 age groups, which were higher than the rates in the last 2 age groups (34.2% and 14.8%) (P = .02, P = .03, P < .001, and P < .001, respectively). The 1-year cumulative incidences of nonrelapse mortality were 10.2%, 0%, 3.4%, and 26.0% in the 4 age groups and 8.1% in all patients. The median times to neutrophil and platelet recovery were 12 days and 14 days after induction chemotherapy, respectively. Five patients had full or mixed donor engraftment, and 30.8% (8 of 26) of patients demonstrated donor microchimerism. Two patients (1.1%) developed severe acute graft-vs-host disease. Conclusions and Relevance Microtransplant achieved a high complete remission rate in AML patients aged 60 to 85 years and higher 1-year overall survival in those aged 60 to 74 years.

Abstract
Objective: To observe the histopathological features of different opportunistic infections and tumors of the intestinal mucosa in AIDS patients, and to explore the correlation between different lesions and CD4+ T lymphocyte levels. Methods: Colonic mucosal biopsy specimens of 263 patients with clinically diagnosed AIDS and abdominal pain, diarrhea, blood in the stool and other gastrointestinal symptoms were collected from Beijing Ditan Hospital from 2010 to 2018. There were 232 males and 31 females, with age range 10-81 (mean 40±13) years. HE staining, histochemical special staining, immunohistochemical staining, and in-situ hybridization were used to detect the expression of different opportunistic infection pathogens, tumors and CD4+ T lymphocytes. Peripheral blood was also taken for CD4+ T lymphocytes, CD8+ T lymphocytes, HIV viral load and routine indicators. Results: The cohort included 263 intestinal mucosal biopsy specimens. There were 175 cases (66.5%) of non-specific inflammation, and pathogens were detected in 41 cases (15.6%), including 20 cases(7.6%) of cytomegalovirus (CMV) infection, 12 cases (4.6%) of mycobacterial infection, eight cases (3.0%) of amoeba infestation, and one case (0.3%) of talaromycesmarneffei infection; there were also 41 (15.6%) neoplastic lesions including 25 cases (9.5%) of intraepithelial neoplasia, 10 cases (3.8%) of adenocarcinoma and squamous cell carcinoma, six cases (2.3%) of lymphoma; and six cases (2.3%) of ulcerative colitis. The peripheral blood CD4+T lymphocyte levels of patients with CMV, mycobacteria and talaromycesmarneffei were less than 200/μL; the peripheral blood CD4+ T lymphocyte level (P<0.01) and intestinal mucosa CD4+T lymphocytes (P<0.01) were all significantly lower than those in patients with non-specific inflammation. The peripheral red blood cells and hemoglobin levels of patients with CMV and mycobacterial infection (P<0.01), adenocarcinoma and squamous cell carcinoma (P<0.05) were significantly lower than those of non-specific inflammation patients. Conclusions: Pathologic examination of intestinal mucosa can identify specific infections and neoplastic lesions in AIDS patients; the most common lesions are non-specific inflammation, and CMV infection is the most common opportunistic infections; CMV, mycobacteria and talaromycesmarneffei infections are associated with decreased levels of CD4+ T lymphocytes in peripheral blood and intestinal mucosa; entamoeba histolytica infestation and non-HIV-related neoplastic lesions such as intraepithelial neoplasia, adenocarcinoma and squamous cell carcinoma are not associated with changes in AIDS immune function.

Abstract
The greater wax moth, Galleria mellonella Linnaeus (Lepidoptera: Galleriinae), is a ubiquitous pest of the honeybee, and poses a serious threat to the global honeybee industry. G. mellonella pheromone system is unusual compared to other lepidopterans and provides a unique olfactory model for pheromone perception. To better understand the olfactory mechanisms in G. mellonella, we conducted a transcriptomic analysis on the antennae of both male and female adults of G. mellonella using high-throughput sequencing and annotated gene families potentially involved in chemoreception. We annotated 46 unigenes coding for odorant receptors, 25 for ionotropic receptors, two for sensory neuron membrane proteins, 22 for odorant binding proteins and 20 for chemosensory proteins. Expressed primarily in antennae were all the 46 odorant receptor unigenes, nine of the 14 ionotropic receptor unigenes, and two of the 22 unigenes coding for odorant binding proteins, suggesting their putative roles in olfaction. The expression of some of the identified unigenes were sex-specific, suggesting that they may have important functions in the reproductive behavior of the insect. Identification of the candidate unigenes and initial analyses on their expression profiles should facilitate functional studies in the future on chemoreception mechanisms in this species and related lepidopteran moths.

Abstract
Neuropathic pain (NP) caused by nerve injury or dysfunction is one of the most challenging neurological diseases. In-depth study of disease signatures contributes to the development of novel target treatment for NP. In this study, we analyzed expression profiles of qualified NP datasets (GSE24982 and GSE63442) deposited at Gene Expression Omnibus database by systematic bioinformatics approaches. We analyzed the differentially expressed genes of high and low pain compared with normal control group, and between spinal nerve ligation (SNL) injury model and sham-operation group. A total of 1,243 upregulated and 1,533 downregulated genes were identified in GSE24982, 380 upregulated and 355 downregulated genes were identified in GSE63442. By comparing low-pain samples with the corresponding sham-operation group, we identified 457 upregulated and 409 downregulated genes. Overlapping genes were screened out and signaling pathway and expression regulation model analyses were performed. SCN10A and SST were identified as biomarkers for NP. In conclusion, our study showed the expression pattern of gene about NP. These identified biomarkers could serve as potential therapeutic targets for treating NP.

Abstract
BACKGROUND We compared Kaposi sarcoma (KS) risk in adults who started antiretroviral therapy (ART) across the Asia-Pacific, South Africa, Europe, Latin, and North America. METHODS We included cohort data of human immunodeficiency virus (HIV)-positive adults who started ART after 1995 within the framework of 2 large collaborations of observational HIV cohorts. We present incidence rates and adjusted hazard ratios (aHRs). RESULTS We included 208140 patients from 57 countries. Over a period of 1066572 person-years, 2046 KS cases were diagnosed. KS incidence rates per 100000 person-years were 52 in the Asia-Pacific and ranged between 180 and 280 in the other regions. KS risk was 5 times higher in South African women (aHR, 4.56; 95% confidence intervals [CI], 2.73-7.62) than in their European counterparts, and 2 times higher in South African men (2.21; 1.34-3.63). In Europe, Latin, and North America KS risk was 6 times higher in men who have sex with men (aHR, 5.95; 95% CI, 5.09-6.96) than in women. Comparing patients with current CD4 cell counts ≥700 cells/µL with those whose counts were <50 cells/µL, the KS risk was halved in South Africa (aHR, 0.53; 95% CI, .17-1.63) but reduced by ≥95% in other regions. CONCLUSIONS Despite important ART-related declines in KS incidence, men and women in South Africa and men who have sex with men remain at increased KS risk, likely due to high human herpesvirus 8 coinfection rates. Early ART initiation and maintenance of high CD4 cell counts are essential to further reducing KS incidence worldwide, but additional measures might be needed, especially in Southern Africa.

Abstract
Studies on insect olfaction have increased our understanding of insect's chemosensory system and chemical ecology, and have improved pest control strategies based on insect behavior. In this study, we assembled the antennal transcriptomes of the lychee giant stink bug, Tessaratoma papillosa, by using next generation sequencing to identify the major olfaction gene families in this species. In total, 59 odorant receptors, 14 ionotropic receptors (8 antennal IRs), and 33 odorant binding proteins (28 classic OBPs and 5 plus-C OBPs) were identified from the male and female antennal transcriptomes. Analyses of tissue expression profiles revealed that all 59 OR transcripts, 2 of the 8 antennal IRs, and 6 of the 33 OBPs were primarily expressed in the antennae, suggesting their putative role in olfaction. The sex-biased expression patterns of these antenna-predominant genes suggested that they may have important functions in the reproductive behavior of these insects. This is the first report that provides a comprehensive resource to future studies on olfaction in the lychee giant stink bug.

Abstract
A elderly woman patient,with a unclear boundary,solid,smooth surface,moderately active mass that estimated 0.4 cm at its greatest diameter in the left lobe of thyroid. Ultrasonography revealed a hypoechoic mass in the left lobe and Computed Tomography showed a 38 mm×25 mm×23 mm oval lesion with uniform density in the left lobe also. The surgical findings revealed tumor located in the inner side of left thyroid lobe near the isthmus,with unclear boundary. Pathological examination showed unclear boundaries between thyroid and tumor,the tumor cells attack into the muscle tissue,braided/ fascicles spindle shaped or star shaped myofibroblasts cells in the tumor area with myxedema inflammatory background and the lesion did not have any mitotic figures. Immunohistochemical analysis indicated that the spindle cells were positive for Vim,ACT,SMA,Bcl2 and ClyD1,and focal lesion histiocytes showed focal positive for CD68,CK and S-100,but negative for DES,Mgo,CD99,CD34,CD117,IgG4,ALK-1.The pathological diagnosis supports inflammatory myofibroblastic tumor of thyroid. Imaging and immunohistochemistry and others are useful in differential diagnosis.

Abstract
Here we describe the combination of three-dimensional (3D) printed chip and automated microfluidic droplet-based screening techniques for achieving massively parallel, nanoliter-scale protein crystallization screening under vapor diffusion mode. We fabricated high-density microwell array chips for sitting-drop vapor diffusion crystallization utilizing the advantage of the 3D-printing technique in producing high-aspect-ratio chips. To overcome the obstacle of 3D-printed microchips in performing long-term reactions caused by their porousness and gas permeability properties in chip body, we developed a two-step postprocessing method, including paraffin filling and parylene coating, to achieve high sealability and stability. We also developed a simple method especially suitable for controlling the vapor diffusion speed of nanoliter-scale droplets by changing the layer thickness of covering oil. With the above methods, 84 tests of nanoliter-scale protein crystallization under vapor diffusion mode were successfully achieved in the 7 × 12 droplet array chip with a protein consumption of 10 nL for each test, which is 20-100 times lower than that in the conventional large-volume screening system. Such a nanoliter-scale vapor diffusion system was applied to two model proteins with commercial precipitants and displayed advantages over that under microbatch mode. It identified more crystallization conditions, especially for the protein samples with lower concentrations.

Abstract
The dysfunction of peripheral immune tolerance plays an important role in the pathogenesis of allergic diseases. Recent reports indicate that micro RNA (miR)-98 is associated with the process of aberrant immune responses. This study aims to test a hypothesis that miR-98 is associated with the pathogenesis of airway allergy via interfering with the development of regulatory B cells (Breg). In this study, patients with airway allergy were recruited into this study. The frequency of Bregs was assessed by flow cytometry. The levels of miR-98 in peripheral B cells were determined by RT-qPCR. A cell-culture model of B cells was developed to test the role of miR-98 in the repressing of interleukin (IL)-10 in B cells. The results showed that the levels of IL-10 in peripheral B cells were significantly lower in patients with airway allergy as compared with healthy subjects. High levels of miR-98 (one of the miR-98 members) were detected in peripheral B cells of patients with airway allergy, which was mimicked by stimulating B cells with IL-4. Histone acetyltransferase p300 was involved in the IL-4-induced miR-98 expression. miR-98 mediated the IL-4-inhibited IL-10 expression in B cells. In conclusion, miR-98 affects the expression of IL-10 in B cells and may be a novel therapeutic target for the treatment of allergic diseases.

Abstract
Regeneration of bone tissue, as well as other tissues, requires involvement and interaction of cells, scaffolds and relevant growth factors, among which growth factors play a crucial role in maintaining the stability of microenvironment. Nel-like-type 1 molecule (NELL-1), a novel growth factor in tissue engineering, has been studied intensively in recent years. Researches mainly covered gene and protein structure and their expression profiling, biological function, molecular mechanisms and disease relevance. NELL-1 expressed in embryonic tissue is essential for growth and development of bone tissue. NELL-1 presents excellent abilities of inducing bone and cartilage regeneration,especially with high specificity to chondrocyte lineage. Compared with classic osteogenic growth factor bone morphogenetic protein 2 (BMP-2), the process of osteogenesis interacted with NELL-1 exhibits stronger specificity, higher bone density and fewerside effects. Furthermore, a recent study shows synergistic effects of NELL-1 and BMP-2. NELL-1 enhances the osteogenic reaction induced by BMP-2 of cells and notably declines inflammation response caused by BMP-2. This review evaluates the current research progress of the function and application of NELL-1 by the systematic method of evidence-based medicine.

Abstract
OBJECTIVE To investigate the efficacy and safety of MA (mitoxantrone and cytarabine) regimen chemotherapy combined with granulocyte-colony stimulating factor (G-CSF)-mobilized family related HLA-haploidentical donor peripheral blood hematopoietic stem cell (G-PBHSC) infusion for the treatment of acute myeloid leukemia (AML) patients aged over 80 years. METHODS Four elderly patients with AML were treated in Chinese Second Artillery General Hospital from August 2008 to September 2013. The proportion of male to female was 1 : 3 and the median age 83 (80-85) years. All patients received programmed infusions of G-PBHSC after MA regimen chemotherapy without graft-versus-host disease (GVHD) prophylaxis. After complete remission (CR), patients only received G-PBHSC infusion without chemotherapy. RESULTS Three cases achieved CR and their disease free survival (DFS) time was 18, 8, 6 months, respectively. 1 case did not reach remission after 2 cycles chemotherapy. The median overall survival (OS) time was 10 (3-20) months. No GVHD was observed in any of the patients during treatment. Concludsion: The combination of chemotherapy and programmed haploidentical G-PBHSC infusion is an alternative approach for AML patients aged over 80 years.

Abstract
The progression of colorectal cancer (CRC) is a multistep process and metastatic CRC is always incurable; consequently, CRC is the leading cause of cancer-related deaths. There is therefore an urgent need for identifying useful biomarkers with enough sensitivity and specificity to detect this disease at early stages, which will significantly reduce the mortality for this malignancy. In this study, we performed an integrating analysis of different RNA-Seq data sets to find new candidate biomarkers for diagnosis, prognosis and as therapeutic targets for this malignancy, as well as to elucidate the molecular mechanisms of CRC carcinogenesis. We identified 883 differentially expressed genes (DEGs) across the studies between CRC and normal control (NC) tissues by combining five RNA-Seq data sets. Gene function analysis revealed high correlation with carcinogenesis. The top 10 most significantly DEGs were further evaluated by quantitative real-time polymerase chain reaction (qRT-PCR) in both rectal cancer (RC) and colon cancer (CC), and the results matched well with integrating data, suggesting that the method of integrating analysis of different RNA-seq data sets is acceptable. Therefore, integrating analysis of different RNA-seq data sets may be a useful way to overcome the limitation of small sample size in a single RNA-seq study. In addition, our study showed that some genes, such as SIM2, ADAMTS6, FOXD4L4 and DNAH5, may have an important role in the development of CRC, which could be applied for diagnosis, prognosis and as therapy for this malignancy. Our findings would also help to understand the pathology of CRC.

Abstract
This article describes the complementary application of non-invasive micro-Raman spectroscopy and energy dispersive X-ray fluorescence spectrometry to the characterization of some ancient Chinese silicate artifacts. A total of 28 samples dated from fourth century BC to third century AD were analyzed. The results of chemical analysis showed that the vitreous PbO-BaO-SiO2 material was used to sinter these silicate artifacts. The barium copper silicate pigments including BaCuSi4O10, BaCuSi2O6 and BaCu2Si2O7 were widely identified from colorful areas of the samples by Raman spectroscopy. In addition, other crystalline phases such as Fe2O3, BaSi2O5, BaSO4, PbCO3 and quartz were also identified. The present study provides very valuable information to trace the technical evolution of man-made barium copper silicate pigments and their close relationship with the making of ancient PbO-BaO-SiO2 glaze and glass.

Abstract
OBJECTIVES The proportion of people living with HIV/AIDS in the ageing population (>50 years old) is increasing. We aimed to explore the relationship between older age and treatment outcomes in HIV-positive persons from the Asia Pacific region. METHODS Patients from the Australian HIV Observational Database (AHOD) and the TREAT Asia HIV Observational Database (TAHOD) were included in the analysis. We used survival methods to assess the association between older age and all-cause mortality, as well as time to treatment modification. We used regression analyses to evaluate changes in CD4 counts after combination antiretroviral therapy (cART) initiation and determined the odds of detectable viral load, up to 24 months of treatment. RESULTS A total of 7142 patients were included in these analyses (60% in TAHOD and 40% in AHOD), of whom 25% were >50 years old. In multivariable analyses, those aged > 50 years were at least twice as likely to die as those aged 30-39 years [hazard ratio (HR) for 50-59 years: 2.27; 95% confidence interval (CI) 1.34-3.83; HR for > 60 years: 4.28; 95% CI 2.42-7.55]. The effect of older age on CD4 count changes was insignificant (p-trend=0.06). The odds of detectable viral load after cART initiation decreased with age (p-trend=< 0.0001). The effect of older age on time to first treatment modification was insignificant (p-trend=0.21). We found no statistically significant differences in outcomes between AHOD and TAHOD participants for all endpoints examined. CONCLUSIONS The associations between older age and typical patient outcomes in HIV-positive patients from the Asia Pacific region are similar in AHOD and TAHOD. Our data indicate that 'age effects' traverse the resource-rich and resource-limited divide and that future ageing-related findings might be applicable to each setting.

Abstract
This study was aimed to investigate the efficacy of Hyper-CVAD/MA regimen chemotherapy combined with haploidentical hematopoietic stem cell infusion for the treatment of lymphoblastic lymphoma/leukemia (LBL/ALL). Seven patients with LBL/ALL were treated in Second Artillery General Hospital from August 2009 to September 2012. All patients received programmed infusions of granulocyte-colony stimulating factor (G-CSF)-mobilized family related HLA-haploidentical donor peripheral blood hematopoietic stem cell (G-PBHSC) after each of cycle of Hyper-CVAD/MA regimen chemotherapy without graft-versus-host disease (GVHD) prophylaxis. A total of four cycles of therapy were planned. The interval between each cycle of treatment was 8 to 12 weeks. By April 2014, the median follow-up time was 41 (20-57) months. The results showed that the 7 patients totally received 30 cycles of treatment, and all patients achieved complete remission (CR). The patients were generally well-tolerated to therapy, and the most significant toxicities of grade 3 to 4 neutropenia and thrombocytopenia developed in nearly all of the patients after each course of the Hyper-CVAD/MA regimen. No GVHD was observed in any of the patients during treatment. Up to now, 5 patients were still alive, 2 patients were died of relapse. It is concluded that the combination of chemotherapy and programmed haploidentical G-PBHSC infusion is a promising approach to the treatment of LBL/ALL.

Abstract
Nondestructive analysis plays an important role in the studies of ancient artifacts. The present paper reports the chemical compositions and micro-area phases of 21 silicate artifacts samples analyzed by portable X-ray fluorescence spectrometer and laser Raman spectrometer. Based on the chemical compositions, these samples can be divided into PbO-BaO-SiO2, K2O-SiO2 glass systems, faience and PbO-BaO glassy faience which were discussed respectively, and preliminary investigation of colorants in different parts of some samples was also involved. By laser Raman spectroscopy, Chinese blue (BaCuSi4O10), Chinese purple (BaCuSi2O6) and Chinese dark blue (BaCu2Si2O7) were identified invasively in the blue pigment of some eye beads and circle beads, and then a variety of mineral phase including quartz, calcite, lead carbonate, burnt umber and terre verte were also analyzed successfully in the same way. According to the archaeological research results, the provenances of these samples were discussed briefly. PbO-BaO-SiO2 glass, K2O-SiO2 ear pendant and PbO-BaO glassy faience were made in China while the faience was suspected to be from the west. Those results illustrated the communications of culture and technologies among different regions of ancient China, and between ancient China and the western regions. The combination of portable X-ray fluorescence spectrometer and laser Raman spectrometer can provide chemical and phase information of relics, and has great advantages in scientific analysis of ancient artifacts, which supports future studies of archaeology.

Abstract
BACKGROUND D-isoascorbic acid is a food antioxidant additive and used in accordance with Good Manufacturing Practice (GMP). High solubility in water (about 150 g/L at 25°C) reduces its effectiveness in stabilizing fats and oils. Our research group had successfully synthesized D-isoascorbyl palmitate using immobilized lipase Novozym 435 as a biocatalyst. Low production efficiency of D-isoascorbyl palmitate is still a problem for industrial production due to the long reaction time of over 24 h. In the present work, ultrasonic treatment was applied for accelerating the reaction process. The operation parameters were optimized to obtain the maximum D-isoascorbyl palmitate conversion rate by using a 5-level-4-factor Central Composite Design (CCD) and Response Surface Methdology (RSM). The reaction apparent kinetic parameters under the ultrasound treatment and mechanical shaking conditions were also determined and compared. RESULTS Results showed that ultrasound treatment decreased the reaction time by over 50%. D-isoascorbyl palmitate yielded to 94.32 ± 0.17% and the productivity reached to 8.67 g L-1 h-1 under the optimized conditions as: 9% of enzyme load (w/w), 61°C of reaction temperature, 1:5 of D- isoascorbic-to-palmitic acid molar ratio, and 137 W of the ultrasound power. The immobilized lipase Novozym 435 could be reused for 7 times with 65% of the remained D-isoascorbyl palmitate conversion rate. The reaction kinetics showed that the maximum apparent reaction rate (vmax) of the ultrasound-assisted reaction was 2.85 times higher than that of the mechanical shaking, which proved that ultrasound treatment significantly enhanced the reaction efficiency. CONCLUSION A systematic study on ultrasound-assisted enzymatic esterification for D-isoascorbyl palmitate production is reported. The results show a promising perspective of the ultrasound technique to reduce the reaction time and improve the production efficiency. The commercial D-isoascorbyl palmitate synthesis will be potentially realized due to this ultrasound-promoted esters synthesis method.

Abstract
Fluoroquinolones are frequently used to treat infectious disease that is caused by Escherichia coli in dairy cattle. However, fluoroquinolone resistance occurs and is due either to chromosomal mutations in the bacterial topoisomerase genes and/or to plasmid-mediated resistance genes. The purpose of this study was to determine the prevalence and molecular characteristics of fluoroquinolone resistance determinants in E. coli strains (n=148) isolated from dairy cattle with bovine endometritis in Inner Mongolia (China). Analysis of the mutations in the quinolone resistance-determining regions of resistant E. coli isolates confirmed previously reported substitutions in the GyrA and ParE. However, we identified additional substitutions in the ParC and GyrB that have not been reported earlier. No plasmid-mediated quinolone resistance genes in any of the isolates were found. The number of point mutations found per isolate correlated with an increase in the minimum inhibitory concentration of ciprofloxacin. Overall, 45.5% of the isolates were positive for the class I integrase gene along with four gene cassettes that were responsible for resistance to trimethoprim (dfr1 and dfrA17) and aminoglycosides (aadA1 and aadA5), respectively. The prevalence of extended-spectrum β-lactamases (ESBLs) was 100%, and the blaTEM gene was predominant in all of the isolates. In conclusion, our results identify the mechanism of quinolone resistance for the first time and reveal the prevalence of integron and ESBLs in E. coli isolates from dairy cattle with bovine endometritis in China after 20 years of quinolone usage in cattle.

Abstract
Background Isoascorbic acid is a stereoisomer of L-ascorbic acid, and widely used as a food antioxidant. However, its highly hydrophilic behavior prevents its application in cosmetics or fats and oils-based foods. To overcome this problem, D-isoascorbyl palmitate was synthesized in the present study for improving the isoascorbic acid’s oil solubility with an immobilized lipase in organic media. The structural information of synthesized product was clarified using LC-ESI-MS, FT-IR, 1H and 13C NMR analysis, and process parameters for high yield of D-isoascorbyl palmitate were optimized by using One–factor-at-a-time experiments and response surface methodology (RSM). Results The synthesized product had the purity of 95% and its structural characteristics were confirmed as isoascorbyl palmitate by LC-ESI-MS, FT-IR, 1H, and 13C NMR analysis. Results from “one–factor-at-a-time” experiments indicated that the enzyme load, reaction temperature and D-isoascorbic-to-palmitic acid molar ratio had a significant effect on the D-isoascorbyl palmitate conversion rate. 95.32% of conversion rate was obtained by using response surface methodology (RSM) under the the optimized condition: enzyme load of 20% (w/w), reaction temperature of 53°C and D- isoascorbic-to-palmitic acid molar ratio of 1:4 when the reaction parameters were set as: acetone 20 mL, 40 g/L of molecular sieves content, 200 rpm speed for 24-h reaction time. Conclusion The findings of this study can become a reference for developing industrial processes for the preparation of isoascorbic acid ester, which might be used in food additives, cosmetic formulations and for the synthesis of other isoascorbic acid derivatives.

Abstract
PURPOSE Despite best current therapies, approximately half of patients with acute myeloid leukemia in first complete remission (AML-CR1) with no HLA-identical donors experience relapse. Whether HLA-mismatched stem-cell microtransplantation as a novel postremission therapy in these patients will improve survival and avoid graft-versus-host disease (GVHD) is still unknown. PATIENTS AND METHODS One hundred one patients with AML-CR1 (9 to 65 years old) from four treatment centers received programmed infusions of G-CSF-mobilized HLA-mismatched donor peripheral-blood stem cells after each of three cycles of high-dose cytarabine conditioning without GVHD prophylaxis. Donor chimerism and microchimerism and WT1+CD8+ T cells were analyzed. RESULTS The 6-year leukemia-free survival (LFS) and overall survival (OS) rates were 84.4% and 89.5%, respectively, in the low-risk group, which were similar to the rates in the intermediate-risk group (59.2% and 65.2%, respectively; P=.272 and P=.308). The 6-year LFS and OS were 76.4% and 82.1%, respectively, in patients who received a high dose of donor CD3+ T cells (≥1.1×10(8)/kg) in each infusion, which were significantly higher than the LFS and OS in patients who received a lower dose (<1.1×10(8)/kg) of donor CD3+ T cells (49.5% and 55.3%, respectively; P=.091 and P=.041). No GVHD was observed in any of the patients. Donor microchimerism (2 to 1,020 days) was detected in 20 of the 23 female patients who were available for Y chromosome analysis. A significant increase in WT1+CD8+ T cells (from 0.2% to 4.56%) was observed in 33 of 39 patients with positive HLA-A*02:01 antigen by a pentamer analysis. CONCLUSION Microtransplantation as a postremission therapy may improve outcomes and avoid GVHD in patients with AML-CR1.

Abstract
We investigated a possible molecular pathogenesis involving retinal ganglion cell apoptosis following transient high intraocular pressure. Changes in the gene expression profiles of the retina were detected via gene chip methodology. Twelve New Zealand white rabbits were randomly assigned to control and 3-min negative pressure suction groups. The control group was treated only with a laser, and the experimental group was also treated with suction for 3 min, using a negative pressure generator. Total RNA was then extracted from the retinal tissue at different recovery stages to analyze gene expression profiles using the Agilent rabbit one-way gene chip. The groups were then compared. Immediately after negative pressure suction induction, 704 genes were differentially expressed. Among these, 485 genes were upregulated, and 219 were downregulated. Expression of the genes encoding CRYAA, CRYAB, and TLR3 genes, which are involved in apoptosis, was elevated. The KRT18 gene, which is involved in apoptosis, had reduced expression. Seven days after negative pressure suction, 482 genes were differentially expressed. Among these, 178 genes were upregulated, and 304 were downregulated. Expression of the genes encoding CRYAB, IL1-BETA and IL1R1, which are involved in apoptosis, was upregulated. Ten days after negative pressure suction, 402 genes were differentially expressed. Of these, 213 genes were upregulated, and 189 were downregulated. Apoptosis genes CRYAB, CRYBA3, CRYBB2, IL1- BETA, and IL1R1 showed higher expression levels. We concluded that negative pressure suction for long periods of time (for example, 3 min) results in changes in gene expression. Genes with higher fold changes help protect retinal ganglion cells from apoptosis. We suggest that promoting the expression of these genes should be considered as a new means for treating ischemic-hypoxic retinopathy.

Abstract
We investigate the influence of thermal effects on the high-speed performance of 1.3-μm InAs/GaAs quantum-dot lasers in a wide temperature range (5-50°C). Ridge waveguide devices with 1.1 mm cavity length exhibit small signal modulation bandwidths of 7.51 GHz at 5°C and 3.98 GHz at 50°C. Temperature-dependent K-factor, differential gain, and gain compression factor are studied. While the intrinsic damping-limited modulation bandwidth is as high as 23 GHz, the actual modulation bandwidth is limited by carrier thermalization under continuous wave operation. Saturation of the resonance frequency was found to be the result of thermal reduction in the differential gain, which may originate from carrier thermalization.

Abstract
The techniques of portable energy-dispersive X-ray fluorescence analysis (PXRF), proton induced X-ray emission spectroscopy (LRS) were employed to analyze the chemical composition, structure and mineral constitution of 12 samples. The results indicated that the chemical compositions determined by PXRF and PIXE are well comparable and most samples are constituted by almost pure jadeite with low concentration of secondary elements. One sample contains a little omphacite and one sample is composed only by omphacite. Raman characteristic peaks of jadeite occurred at 201, 372, 698, 985 and 1 037 cm(-1), while those of omphacite located at 680 and 1 017 cm(-1). By using laser Raman spectroscopy for testing the fissures of the samples, wax in 3 samples and epoxy resin in one sample were found. Raman characteristic peaks of wax located at 2 846 and 2 880 cm(-1) and those of epoxy resin occurred at 2 924 and 3 065 c(-1). The application of nondestructive techniques in jadeite jade broadens the range of samples for future study and provides technical support for jadeite jade's further study, identification and classification.

Abstract
This study was aimed to investigate the effect of recombinant human granulocyte colony-stimulating factor(G-CSF) on murine thymocyte emigration and cell cycle alteration after a sublethal dose of gamma-irradiation. Female BALB/c mice were given 6.0 Gy γ-ray total body irradiation and then randomly divided into G-CSF and control groups. Mice in the G-CSF group were injected recombinant human G-CSF 100 µg/(kg·d) subcutaneously once daily for 14 consecutive days and mice in the control group were given the same volume of phosphate buffered solution. Thymocyte cycle alteration and the proportion of apoptosis cells were detected by flow cytometry within 72 hours after irradiation. Real-time PCR was used for detection and quantitation of murine T cell receptor rearrangement excision circles (sjTREC) of the thymic cells at 30 and 60 day after the irradiation. The results showed that at 6 hour after irradiation G-CSF could significantly increase the thymic cells in G(0)/G(1) phase, G-CSF vs control: (82.0 ± 5.0)% vs (75.9 ± 2.8)% (p < 0.05), and decrease the thymic cells in S phase, G-CSF vs control: (10.2 ± 4.8)% vs (15.7 ± 2.3)% (p < 0.05), but G-CSF seemed have no evident effects on the percentage of thymic cells in G(2)/M phase. G-CSF could also protect thymocytes from apoptosis at 6 hour and 12 hour after irradiation the percentages of apoptosis cells in G-CSF group were (11.5 ± 2.4)% and (15.5 ± 3.3)%, respectively, which were significantly lower than that of the control group (16.5 ± 2.2)% and (22.6 ± 0.7)%, respectively (p < 0.05). The sjTREC copy amount was conspicuously higher in G-CSF group than that in the control at 30 day after irradiation (p < 0.01), but the preponderance disappeared 60 days later. It is concluded that G-CSF has a positive effect on the thymic cell cycle alteration to protect thymocytes from apoptosis and enhance the recent thymocyte emigration, which may contribute to the central immune reconstitution after irradiation.

Abstract
A rapid method has been developed based on the sample preparation procedure named as QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe), combined with reversed-phase high performance liquid chromatography with fluorescence detector and C18 column after pre-column derivatization using o-phthalaldehyde and 2-mercaptoethanol to determine dopamine in porcine muscle. Methanol and deionized water (0.1% acetic acid, v/v) with a ratio of 60:40 was used as mobile phase. The flow rate was 0.8 mL/min and dopamine was eluted within 15 min. The linearity range was 0.003-8 μg/mL with r=0.9992. The detection limit for dopamine was 4 μg/kg and the quantification limit was 9 μg/kg. Recovery studies were carried out at 0.1, 0.5 and 1.0 mg/kg fortification levels and the average recoveries obtained ranged from 90.4% to 98.2% with relative standard deviations between 3.5% and 8.1%. The method was found to be suitable for detection of dopamine in animal product tissues at the maximum residue level.

Abstract
This study was purposed to investigate the effect of G-CSF on the proliferation, differentiation, and cell cycle distribution of thymocytes in sublethally irradiated mice. Female BALB/c mice were exposed to 6.0 Gy γ-ray irradiation and then randomly divided into control and G-CSF treatment group. In the treatment group rhG-CSF 100 µg/(kg·d) was given subcutaneously for 14 continuous days and to make sure the first injection was given within 1 hour after irradiation. Cell cycle distribution and apoptosis of thymocytes were detected within 72 hours after irradiation. Subpopulations of CD4(-)CD8(-) cells and sequential changes in the distribution of CD4(+)CD8(+), CD8(+)CD4(-), CD8(-)CD4(+) cells were detected by a three-color flow cytometry during a four-weeks period after irradiation. The results showed that in G-CSF treatment group marked increase of cells in G(0)/G(1) phase (G-CSF vs control: 82.0 ± 5.0% vs 75.9 ± 2.8%) (p < 0.05) and a decrease of cells in S phase (G-CSF vs control: 10.2 ± 4.8% vs 15.7 ± 2.3%) (p < 0.05)could be observed as early as 6 hours after irradiation, but G-CSF seems have no evident effects on the cells in G(2)/M phase. G-CSF could also protect thymocytes against apoptosis. 6 and 12 hours after irradiation the apoptosis rates of thymic cells in G-CSF treatment group were 11.5 ± 2.4% and 15.5 ± 3.3% respectively, while in the control group the apoptosis rates were 16.5 ± 2.2% and 22.6 ± 0.7% respectively. Comparison between the two group demonstrated significant difference (p < 0.05). CD4(-)CD8(-) double negative thymocytes (DN)can be defined as DN1-4 according to their maturation. G-CSF treatment resulted in a significant increase in DN1 thymocytes and promoted their proliferation and differentiation to a more mature DN3 and DN4 stage. G-CSF could enhance the recovery of CD4(+)CD8(+) thymocytes and mitigate their relapse during reconstitution. The percentage of CD4(+)CD8(+) thymocytes in the G-CSF treatment group 28 days after irradiation was significantly higher than that of the control group (71.0 ± 6.3% vs 25.5 ± 6.3%) (p < 0.05). It is concluded that G-CSF has a positive effects on the thymic cell cycle distribution, proliferation and differentiation, which may contribute to the reconstitution of central immune system after acute irradiation.

Abstract
This study was aimed to investigate the expression level of NOV and BNIP3 mRNA in mice myelomonocytic leukemia (AML-M(4)) and its significance. The mice were inoculated intravenously with myelomonocytic leukemia cells of WEHI-3, and divided randomly into chemotherapy group and control (untreated) group. Bone marrow samples were then collected from both groups at different times. The NOV and BNIP3 mRNA expression were detected by TaqMan quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR), and the relationship between these expression levels and clinical significance in leukemia incidence and progression were analyzed with β-actin as the housekeeping gene. The results showed that the mean values of NOV and BNIP3 increased gradually from 2 weeks after inoculation and achieved highest level at death in control group. Expression level of NOV increased from 1.85E-05 before inoculation to 3.57E-02 at death (p < 0.05), and BNIP3 from 3.44E-03 to 3.48E-02. While 2 gene expression in the chemotherapy group decreased quickly to 2.51E-05 and 1.58E-03 (p < 0.05) respectively after chemotherapy, which were close to the level before inoculation (p > 0.05). The 2 gene expressions again rose at relapse, and difference of expression level between 2 group at death were no statistically significant (p > 0.05). It is concluded that the expression of NOV and BNIP3 in leukemia AML-M(4) is significantly higher than that in normal controls, of which high level expression is an important factor in the development of leukemia. Close relation between the therapeutic effect and expression level of these two genes suggests the great value in prognostic evaluation and MRD detection.

Abstract
Cytoplasmic male sterility (CMS) has widely been used as an efficient pollination control system in rapeseed hybrid production. Identification of cytoplasm type of rapeseed accessions is becoming the most important basic work for hybrid-rapeseed breeding. In this study, we report a simple multiplex PCR method to distinguish the existing common cytoplasm resources, Pol, Nap, Cam, Ogu and Ogu-NWSUAF cytoplasm, in rapeseed. Cytoplasm type of 35 F(1) hybrids and 140 rapeseed open pollinated varieties or breeding lines in our rapeseed breeding programme were tested by this method. The results indicated that 10 of 35 F(1) hybrids are the Nap, and 25 the Pol cytoplasm type, which is consistent with the information provided by the breeders. Out of 140 accessions tested, 100 (71.4%), 21 (15%) and 19 (13.6%) accessions possess Nap, Cam and Pol cytoplasm, respectively. All 19 accessions with Pol cytoplasm are from China. Pedigree analysis indicated that these accessions with Pol cytoplasm were either restorers for Pol CMS, including Shaan 2C, Huiyehui, 220, etc. or derived from hybrids with Pol CMS as female parent. Our molecular results are consistent with those of the classical testcross, suggesting the reliability of this method. The multiplex PCR assay method can be applied to CMS "three-line" breeding, selection and validation of hybrid rapeseed.

Abstract
Laser Raman spectroscopic technique is one of the essential methods in scientific archaeological research, which belongs to the nondestructive analysis. As a very good nondestructive analysis approach, it has not been widely applied in the research of the Chinese ancient jade artifacts. First of all in the present paper the fundamentals of laser Raman spectroscopic technique and the new research progress in this field were reviewed. Secondly, the Raman spectra of five familiar jades including nephrite (mainly composed of tremolite), Xiuyan Jade (mainly composed of serpentine), Dushan Jade (mainly composed of anorthite and Zoisite), turquoise and lapis lazuli were summarized respectively. As for an example, the Raman spectra of the four Chinese ancient jade artifacts excavated from Liangzhu Site of Zhejiang Province and Yinxu Site of Anyang in Henan Province were compared with that of the nephrite sample in Hetian of Xinjiang Province. It was shown that the Raman spectroscopic technique is a good nondestructive approach to the identification and investigation of the structures and mineral composition of Chinese ancient jade artifacts. Finally, the limitations and the foreground of this technique were discussed.

Abstract
The activation of T lymphocytes plays a very important role in T-cell-mediated immune response. Though there are many related literatures, the changes of membrane surface nanostructures and adhesion property of T lymphocytes at different activation stages have not been reported yet. However, these investigations will help us further understand the biophysical and immunologic function of T lymphocytes in the context of activation. In the present study, the membrane architectures of peripheral blood T lymphocytes were obtained by AFM, and adhesion force of the cell membrane were measured by acquiring force-distance curves. The results indicated that the cell volume increased with the increases of activation time, whereas membrane surface adhesion force decreased, even though the local stiffness for resting and activated cells is similar. The results provided complementary and important data to further understand the variation of biophysical properties of T lymphocytes in the context of in vitro activation.

Abstract
Some allelic forms of low-molecular-weight glutenin subunit (LMW-GS) can greatly influence the end-use of wheat flours, understanding the function of each allele of LMW-GS is important to wheat quality breeding. A LMW-GS gene XYGluD3-LMWGS 1(AY263369) has been cloned from bread wheat cultivar Xiaoyan 6. The deduced protein contained nine cystine residues, one more than that in all other LMW-GSs reported previously, indicating that it is either a new gene or a new allele of a known LMW-GS gene. In this study, the gene was expressed in E. coil in large scale for the testing of its functional property. Reactive Red 120-Agarose resin was used efficiently to purify the expressed LMW-GS proteins from bacteria, with the lactic acid-sodium lactate buffer (pH 4.5) which contained low concentration SDS as elution solution. The purified protein (belonging to the LMW-m family, MW about 35 KDa) was supplemented into a base flour, the results of 10 g dough mixing test indicated that incorporation of the LMW-GS increased the strength of the dough, with significant increases in mixing time (MT) and peak width (PW), and decrease in breakdown in resistance (RBD) compared with the control. In addition, the dough with incorporation of the LMW-GS had more glutenin macropolyeric protein than the control, suggesting that the LMW-GS participated in forming larger glutenin polymers, and greatly contributed to dough strength. The changes in mixing parameters and the amount of glutenin macropolyeric protein were related to the quantity of incorporating subunits.

Abstract
H22 is a major resistance gene conferring high-level of antibiosis to Hessian fly [Mayetiola destructor (Say)] larvae. It was previously assigned to wheat chromosome 1D through monosomic analysis (Raupp et al. in J Hered 84:142-145, 1993). The objective of this study was to identify molecular markers that can be used for marker-assisted selection for wheat breeding, and to further map this gene toward map-based cloning. Forty-five simple sequence repeat (SSR) and sequence-tagged site (STS) markers specific to chromosome 1D were evaluated for linkage to H22 using a segregating population consisting of 192 F(2:3) families, which were derived from the cross Tugela-Dn1 x KS85WGRC01(H22). The STS Xhor2kv and SSR Xgdm33 are two flanking markers that are tightly linked to H22 at genetic distances of 0.3 and 1.0 cM, respectively. Five other SSR markers including Xgpw7082, Xwmc147, Xcfd15, Xwmc432 and Xwmc336 were also linked to H22 at the distance from 0.8 to 20.8 cM. Analysis of Chinese Spring (CS) deletion lines revealed that all the H22-linked markers are located distal to the breakpoint of del 1DS-5, indicating that the H22 gene is located at the distal 30% region on the short arm of wheat chromosome 1D. Genomic comparison suggested that the H22 gene is located in the same or similar chromosomal region as the leaf rust resistance genes Lr21 and Lr40 on 1DS, and orthologous to the H9 gene cluster of 1AS.

Abstract
PCR technique was employed to isolate gene homologous to the MS2Bnap (X99922.1) from two rapeseed (Brassica napus L.) dominant digenic male sterile lines, namely 220A (male sterile) and 220B (male fertile), 6A (male sterile) and 6C (male fertile). The isolated 2,581 bp sequences from 220A (named 220A-gDNA, GenBank accession number AY288778), 220B (220B-gDNA, AY257490), 6A (6A-gDNA, DQ060318) and 6C (6C-gDNA, DQ060319) all contained six introns. Forty-one single nucleotide polymorphism (SNP) sites were detected by alignment of these four sequences, seven of them dispersed in the exon regions. Two SNPs (1247, 1656) were detected between 220A-gDNA and 220B-gDNA, and the one at nucleotide 1247 of 220A-gDNA with A replaced by C was a missense mutation, which may be the putative male sterility site in 220A. All eight SNPs identified between 6A-gDNA and 6C-gDNA were located in the third intron, so the proteins encoded by them are the same. The one SNP between 6A-/6C-gDNA and 220A-/220B-gDNA at nucleotide 2474 of 220A-/220B-gDNA with C replaced by G was a missense mutation. Mutation site of BNMS2PROT (CAA68190.1) encoded by MS2Bnap in 220A(254) and 6A/6C(584) is different, which indicated dominant digenic male sterile line 220AB and 6CA have some difference in the molecular level. Comparison of structure of MS2Bnap in B. napus with that of MS2 in Arabidopsis thaliana revealed that the similarity of exons between these two genes is higher than that of introns.

Abstract
AIM: To explore the effect of dietary composition on the levels of blood glucose lipids as well as the health of individuals with workplace-eating habits.
METHODS: According to the results of questionnaires and medical examination, 100 adults were randomly recruited from a community of Beijing, in which annual medical examination was regularly performed in May. The related data were collected from 2000 to 2004.
RESULTS: The level of aspartate aminotransferase (AST) had a tendency to elevate year by year, and it was significantly different except that between the last two years. Meanwhile, the level of blood glucose tended to increase year by year, and it was markedly different except that between the third and second year as well as that between the last two years. Total cholesterol (TCH) level was enhanced year by year, and it was significant different except that between the second and first year, the fourth and third year as well as that between the fifth and fourth year. Triglycerides (TG) level also had the trend of being elevated year by year, but it had no significant difference except that between the fifth and first year.
CONCLUSION: There are some factors that contributes to the elevation of AST and blood glucose levels in the populations with workplace-eating habits, but their contributions for elevating blood lipid level are not obvious.

A method has been developed to predict the retention times of 209 individual polybrominated diphenyl congeners for different temperature programs. The retention equations lnk'=A+B/T of five PBBs in gas chromatography (GC) were used to evaluate the properties of the regression coefficients A and B, which are widely accepted as being highly reliable chromatographic retentions. The quantitative relationships between the A and B values of PCBs and those of PBBs were found. The regression equations derived have coefficients of determination greater than 0.999. The A, B values of any PBB can be predicted by using the A, B values of the PCB according to these relationships. Using these predicted A and B values, the retention times of all PBBs can be predicted. This is an important advance in the identification of PBBs because at present there are only a few PBB standards available.

Abstract
Genetic distances (GDs) based on morphological characters, isozymes and storage proteins, and random amplified polymorphic DNAs (RAPD) were used to predict the performance and heterosis of crosses in oilseed rape (Brassica napus L.). Six male-sterile lines carrying the widely used Shaan2A cytoplasm were crossed with five restorer lines to produce 30 F1 hybrids. These 30 hybrids and their parents were evaluated for seven agronomically important traits and their mid-parent heterosis (MPH) at Yangling, Shaanxi province in Northwest China for 2 years. Genetic similarity among the parents based on 34 isozyme and seven protein markers was higher than that based on 136 RAPDs and/or 48 morphological markers. No significant correlation was detected among these three sets of data. Associations between the different estimates of GDs and F1 performance for some agronomic traits were significant, but not for seed yield. In order to enhance the predicting efficiency, we selected 114 significant markers and 43 favoring markers following statistical comparison of the mean values of the yield components between the heterozygous group (where the marker is present only in one parent of each hybrid) and the homozygous group (where the marker is either present or absent in both parents of each hybrid) of the 30 hybrids. Parental GD based on total polymorphic markers (GDtotal, indicating general heterozygosity), significant markers (GDsign, indicating specific heterozygosity) and favoring markers (GDfavor, indicating favoring-marker heterozygosity) were calculated. The correlation between GDfavor or GDsign and hybrid performance was higher than the correlation between GDtotal and hybrid performance. GDsign and GDfavor significantly correlated with plant height, seeds per silique and seed yield, but not with the MPH of the other six agronomic traits with the exception of plant height. The information obtained in this study on the genetic diversity of the parental lines does not appear to be reliable for predicting F1 yield and heterosis.

Abstract
AIMS Several studies on space-time clustering have been reported in childhood diabetes, but the findings are conflicting. The present study was undertaken to examine whether such clustering could be detected at either birth or the time of diagnosis in the far South-west of England. METHODS A cohort of 518 children aged 0-15 years and diagnosed with Type 1 diabetes from 1975 to 1996 contained in the population-based Cornwall and Plymouth Children's Diabetes Register (CPCDR) were included in the analyses. The case ascertainment for this register is estimated to be 94.4% complete. Mantel's modification of Knox's method was employed. A method based on K-function was also used, for the first time, to investigate the space-time clustering of diabetes. RESULTS Significant space-time clustering at diagnosis was found by the Knox's test in the following combinations of critical cut-off thresholds: 25, 35 and 50 km and 90, 270 and 360 days (all P < 0.05), with the highest significance found at 35 km and 360 days (P = 0.0011). K-function analysis also confirmed the overall clustering (P = 0.013). CONCLUSIONS There is strong evidence of space-time clustering in the onset of childhood Type 1 diabetes in Devon and Cornwall, England. These results lend some support to the hypothesis that viral infections and some unknown localized environmental factors play a role in the development of childhood Type 1 diabetes.

Abstract
AIMS Previous studies have reported inconsistent results on the association between some compositions (e.g. nitrate) in domestic water and the risk of childhood-onset Type 1 diabetes mellitus. This study aimed to examine the relationship between nitrate, zinc and magnesium in drinking water and the risk of childhood-onset Type 1 diabetes mellitus. METHODS The study covers the Cornwall and the former Plymouth Health Authority Regions in the far south-west of England. Five hundred and seventeen children, aged 0-15 years, diagnosed with Type 1 diabetes mellitus between 1975 and 1996, were identified for inclusion in the study. Domestic water data (nitrate, Zn, Mg, Cu, Al, Ca, Fe and Mn) between 1993 and 1997 were provided by South-west Water Plc, UK, for each of the 40 Water Supply Zones in which the subjects had been resident at the time of diagnosis. The standardized incidence ratio (SIR) of the disease was calculated for each Water Supply Zone using the UK 1991 census population data. The relationship between the SIR of the disease and the water quality indicators in thirds (three strata of low, medium and high concentrations) was examined by chi2 test for trend and Poisson regression analysis. RESULTS The initial analyses by chi2 test for trend on the relation of SIRs and drinking water compositions suggested that copper, magnesium and nitrate might have some protective effects, but Poisson regression analyses showed that only zinc and magnesium were significant factors. The data suggest that the incidence rate of childhood diabetes is significantly lower when the concentrations of zinc and magnesium in the domestic drinking water are in the range 22.27-27.00 microg/l (incidence rate ratio (IRR), 0.76; 95% CI, 0.59-0.97) and greater than 2.61 mg/l (IRR, 0.72; 95% CI, 0.58-0.91), respectively. CONCLUSIONS Our findings suggest evidence of a possible association between zinc and magnesium in the domestic drinking water and childhood diabetes in the far south-west of England. However, these possible protective effects of zinc and magnesium in domestic drinking water warrant further confirmation.

Abstract
The high molecular weight glutenin subunits 14 and 15 were purified from cultivars of bread wheat (Triticum aestivum) Xiaoyan 6 by preparative sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) appled a new method for visualizing protein in gels. N-terminal amino acid sequences were homologous comparing with other High-Molecular-Weight glutenin subunits. The result suggested that they were basic protein analyzed by two-dimensional electrophoresis of IEF(Isoelectric Focussing) x SDS-PAGE and NEPHGE(Non-Equilibrium PI-gradient Electrophoresis) x SDS-PAGE.
