Abstract
AIMS Inflammation is central to the pathogenesis of metabolic syndrome (MetS). Leukocyte cell-derived chemotaxin 2 (LECT2) is constitutively secreted in response to inflammatory stimuli and oxidative stress contributing to tissue or systemic inflammation. We explored the relationship between LECT2 levels and MetS severity in humans and mice. METHODS Serum LECT2 levels were measured in 210 participants with MetS and 114 without MetS (non-MetS). LECT2 expression in the liver and adipose tissue was also examined in mice fed a high-fat diet (HFD) and genetically obese (ob/ob) mice. RESULTS Serum LECT2 levels were significantly higher in MetS participants than in non-MetS participants (7.47[3.36-17.14] vs. 3.74[2.61-5.82], P < 0.001). Particularly, serum LECT2 levels were significantly elevated in participants with hypertension, central obesity, diabetes mellitus (DM), hyperglycaemia, elevated triglyceride (TG) levels, and reduced high-density lipoprotein cholesterol (HDL-C) levels compared to those in participants without these conditions. Pearson's correlation analysis showed that serum LECT2 levels were positively associated with conventional risk factors in all patients. Moreover, LECT2 was positively associated with the number of MetS components (r = 0.355, P < 0.001), indicating that higher serum LECT2 levels reflected MetS severity. Multivariate regression analysis revealed that a one standard deviation increase in LECT2 was associated with an odds ratio of 1.52 (1.01-2.29, P = 0.044) for MetS prevalence after adjusting for age, sex, body mass index, waist circumference, smoking status, white blood cell count, fasting blood glucose, TG, total cholesterol, HDL-C, blood urea nitrogen, and alanine aminotransferase. Receiver operating characteristic curve analysis confirmed the strong predictive ability of serum LECT2 levels for MetS. The optimum serum LECT2 cut-off value was 9.05. The area under the curve was 0.73 (95% confidence interval 0.68-0.78, P < 0.001), with a sensitivity and specificity of 45.71% and 95.61%, respectively. Additionally, LECT2 expression levels were higher at baseline and dramatically enhanced in metabolic organs (e.g. the liver) and adipose tissue in HFD-induced obese mice and ob/ob mice. CONCLUSIONS Increased LECT2 levels were significantly and independently associated with the presence and severity of MetS, indicating that LECT2 could be used as a novel biomarker and clinical predictor of MetS.

Abstract
BACKGROUND Pulmonary hypertension (PH) is a progressive and life-threatening disease characterized by pulmonary vascular remodeling, which involves aberrant proliferation and apoptosis resistance of the pulmonary arterial smooth muscle cells (PASMCs), resembling the hallmark characteristics of cancer. In cancer, the HMGB2 (high-mobility group box 2) protein promotes the pro-proliferative/antiapoptotic phenotype. However, the function of HMGB2 in PH remains uninvestigated. METHODS Smooth muscle cell (SMC)-specific HMGB2 knockout or HMGB2-OE (HMGB2 overexpression) mice and HMGB2 silenced rats were used to establish hypoxia+Su5416 (HySu)-induced PH mouse and monocrotaline-induced PH rat models, respectively. The effects of HMGB2 and its underlying mechanisms were subsequently elucidated using RNA-sequencing and cellular and molecular biology analyses. Serum HMGB2 levels were measured in the controls and patients with pulmonary arterial (PA) hypertension. RESULTS HMGB2 expression was markedly increased in the PAs of patients with PA hypertension and PH rodent models and was predominantly localized in PASMCs. SMC-specific HMGB2 deficiency or silencing attenuated PH development and pulmonary vascular remodeling in hypoxia+Su5416-induced mice and monocrotaline-treated rats. SMC-specific HMGB2 overexpression aggravated hypoxia+Su5416-induced PH. HMGB2 knockdown inhibited PASMC proliferation in vitro in response to PDGF-BB (platelet-derived growth factor-BB). In contrast, HMGB2 protein stimulation caused the hyperproliferation of PASMCs. In addition, HMGB2 promoted PASMC proliferation and the development of PH by RAGE (receptor for advanced glycation end products)/FAK (focal adhesion kinase)-mediated Hippo/YAP (yes-associated protein) signaling suppression. Serum HMGB2 levels were significantly increased in patients with PA hypertension, and they correlated with disease severity, predicting worse survival. CONCLUSIONS Our findings indicate that targeting HMGB2 might be a novel therapeutic strategy for treating PH. Serum HMGB2 levels could serve as a novel biomarker for diagnosing PA hypertension and determining its prognosis.

Abstract
BACKGROUND T cells are central to the immune responses contributing to hypertension. LGMN (legumain) is highly expressed in T cells; however, its role in the pathogenesis of hypertension remains unclear. METHODS Peripheral blood samples were collected from patients with hypertension, and cluster of differentiation (CD)4+ T cells were sorted for gene expression and Western blotting analysis. TLGMNKO (T cell-specific LGMN-knockout) mice (Lgmnf/f/CD4Cre), regulatory T cell (Treg)-specific LGMN-knockout mice (Lgmnf/f/Foxp3YFP Cre), and RR-11a (LGMN inhibitor)-treated C57BL/6 mice were infused with Ang II (angiotensin II) or deoxycorticosterone acetate/salt to establish hypertensive animal models. Flow cytometry, 4-dimensional label-free proteomics, coimmunoprecipitation, Treg suppression, and in vivo Treg depletion or adoptive transfer were used to delineate the functional importance of T-cell LGMN in hypertension development. RESULTS LGMN mRNA expression was increased in CD4+ T cells isolated from hypertensive patients and mice, was positively correlated with both systolic and diastolic blood pressure, and was negatively correlated with serum IL (interleukin)-10 levels. TLGMNKO mice exhibited reduced Ang II-induced or deoxycorticosterone acetate/salt-induced hypertension and target organ damage relative to wild-type (WT) mice. Genetic and pharmacological inhibition of LGMN blocked Ang II-induced or deoxycorticosterone acetate/salt-induced immunoinhibitory Treg reduction in the kidneys and blood. Anti-CD25 antibody depletion of Tregs abolished the protective effects against Ang II-induced hypertension in TLGMNKO mice, and LGMN deletion in Tregs prevented Ang II-induced hypertension in mice. Mechanistically, endogenous LGMN impaired Treg differentiation and function by directly interacting with and facilitating the degradation of TRAF6 (tumor necrosis factor receptor-associated factor 6) via chaperone-mediated autophagy, thereby inhibiting NF-κB (nuclear factor kappa B) activation. Adoptive transfer of LGMN-deficient Tregs reversed Ang II-induced hypertension, whereas depletion of TRAF6 in LGMN-deficient Tregs blocked the protective effects. CONCLUSIONS LGMN deficiency in T cells prevents hypertension and its complications by promoting Treg differentiation and function. Specifically targeting LGMN in Tregs may be an innovative approach for hypertension treatment.

Abstract
PURPOSE/OBJECTIVE(S) Effective, non-toxic, and targeted induction of lung cancer cell death is urgently needed. The goal of this research is to create a new implantable battery-free therapeutic pellet with integrated drug microneedles that allows for wireless photodynamic therapy (PDT) and targeted release of a ferroptosis inducer (Imidazole ketone erastin, IKE) into tumor tissue. MATERIALS/METHODS A wireless power unit, μ-LED illuminant, a flexible control circuit, and an IKE-stored biodegradable microneedle enclosed in polydimethylsiloxane (PDMS) were all built into an integrated therapeutic pellet. Lung cancer cells were used to illustrate the in vitro viability and molecular biological processes of this system. Therapeutic pellet implanted into the LLC xenograft C57BL/6 model. PDT was conducted by 660 nm laser irradiation after injecting a photosensitizer (Chlorin e6, Ce6) and targeted IKE released into the tumor. Systematically analyzing the therapeutic effects on lung cancer and toxic side-effects. RESULTS The PDT-IKE group reduced cellular viability by 90% compared to the control group at the cellular level. In mouse model studies, the PDT-IKE group suppressed tumors at 78.8%, three or four times greater than the PDT (26.6%) or IKE (19.2%) group alone. The PDT-IKE group also controlled IKE release more precisely with heated electrodes, reducing nephrotoxicity and improving safety. Moreover, the combination of PDT and IKE can effectively cause ferroptosis in tumor cells, both in vivo and in vitro. CONCLUSION A new implantable battery-free therapeutic pellet was designed for wireless PDT with integrated IKE microneedles to induce obvious ferroptosis in lung cancer. The proposed pellet would provide a promising strategy for cancer treatment.

Abstract
Solar flares are one of the severest solar activities that have important effects on near-Earth space. Previous studies have shown that flight arrival delays increase as a result of solar flares, but the intrinsic mechanism behind this relationship is still unknown. In this study, we conducted a comprehensive analysis of flight departure delays during 57 solar X-ray events by using a huge amount of flight data (~ 5 × 106 records) gathered over a 5-year period. It is found that the average flight departure delay time during solar X-ray events increased by 20.68% (7.67 min) compared to quiet periods. Our analysis also revealed apparent time and latitude dependencies, with flight delays being more serious on the dayside than on the nightside and longer (shorter) delays tending to occur in lower (higher) latitude airports during solar X-ray events. Furthermore, our results suggest that the intensity of solar flares (soft X-ray flux) and the Solar Zenith Angle directly modulate flight departure delay time and delay rate. These results indicate that communication interferences caused by solar flares directly affect flight departure delays. This work expands our conventional understanding of the impacts of solar flares on human society and provides new insights for preventing or coping with flight delays.

Abstract
Objective: To explore the safety and feasibility of stereotactic radiation therapy (SBRT) strategy for irradiating porcine ventricular septum, see if can provide a preliminary experimental evidence for clinical SBRT in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: Five male pigs (39-49 kg, 6 months old) were used in this study. Pigs were irradiated at doses of 25 Gy (n=2) or 40 Gy (n=3). Delineation of the target volume was achieved under the guidance of 3-dimensional CT image reconstruction, and SBRT was then performed on defined target volume of porcine ventricular septum. Blood biomarkers, electrocardiogram and echocardiography parameters were monitored before and after SBRT. Pathological examination (HE staining, Masson staining) was performed on the target and non-target myocardium at 6 months post SBRT. Results: SBRT was successful and all animals survived to the designed study endpoint (6 months) after SBRT. Serum cardiac troponin T (cTnT) level was significantly higher than the baseline level at 1 day post SBRT, and reduced at 1 week after SBRT, but was still higher than the baseline level(P<0.05). Serum N-terminal pro-B type natriuretic peptide (NT-proBNP) was also significantly increased at 1 day post SBRT (P<0.05) and returned to baseline level at 1 week post SBRT. The serum NT-proBNP level was (249±78), (594±37) and (234±46) pg/ml, respectively, and the cTnT was (14±7), (240±40) and (46±34) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 40 Gy dose group. The serum NT-proBNP level was (184±20), (451±49) and (209±36) pg/ml, respectively, the cTnT values were (9±1), (176±29) and (89±27) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 25 Gy dose group. Both NT-proBNP and cTnT values tended to be higher post SBRT in the 40 Gy dose group as compared with the 25 Gy dose group, but the difference was not statistically significant (P>0.05). The left ventricular ejection fraction and the left ventricular end-diastolic diameter remained unchanged before and after SBRT (P>0.05). The interventricular septum thickness showed a decreasing trend at 6 months after SBRT, but the difference was not statistically significant ((9.54±0.24) mm vs. (9.82±8.00) mm, P>0.05). The flow velocity of the left ventricular outflow tract, and the valve function and morphology were not affected by SBRT. At 6 months after SBRT, HE staining revealed necrosis in the irradiated target area of the myocardium in the 40 Gy dose group and the 25 Gy dose group, and the degree of necrosis in the irradiated interventricular septum was more obvious in the 40 Gy dose group as compared with the 25 Gy group. The combined histological analysis of the two groups showed that the necrotic area of the irradiated target area accounted for (26±9)% of the entire interventricular septum area, which was higher than that of the non-irradiated area (0) (P<0.05). There was no damage or necrosis of myocardial tissue outside the target irradiation area in both groups. The results of Masson staining showed that the percentage area of myocardial fibrosis was significantly higher in the irradiated target area than non-irradiated area ((12.6±5.3)% vs. (2.5±0.8)%, P<0.05). Conclusion: SBRT is safe and feasible for irradiating porcine ventricular septum.

Abstract
BACKGROUND AND PURPOSE Radiation necrosis, for which abnormal WM enhancement is a hallmark, is an uncommon complication of craniospinal irradiation in children with medulloblastoma. The magnetization transfer ratio measures macromolecular content, dominated by myelin in the WM. We investigated whether the pretreatment supratentorial (nonsurgical) WM magnetization transfer ratio could predict patients at risk for radiation necrosis after radiation therapy for medulloblastoma. MATERIALS AND METHODS Ninety-five eligible patients with medulloblastoma (41% female; mean age, 11.0 [SD, 5.4] years) had baseline balanced steady-state free precession MR imaging before proton or photon radiation therapy. Associations among baseline supratentorial magnetization transfer ratio, radiation necrosis (spontaneously resolving/improving parenchymal enhancement within the radiation field)3, age, and the presence of visible brain metastases were explored by logistic regression and parametric/nonparametric techniques as appropriate. RESULTS Twenty-three of 95 (24.2%) children (44% female; mean age, 10.7 [SD, 6.7] years) developed radiation necrosis after radiation therapy (19 infratentorial, 1 supratentorial, 3 both). The mean pretreatment supratentorial WM magnetization transfer ratio was significantly lower in these children (43.18 versus 43.50, P = .03). There was no association between the supratentorial WM magnetization transfer ratio and age, sex, risk/treatment stratum, or the presence of visible brain metastases. CONCLUSIONS A lower baseline supratentorial WM magnetization transfer ratio may indicate underlying structural WM susceptibility to radiation necrosis and may identify children at risk for developing radiation necrosis after craniospinal irradiation for medulloblastoma.

Abstract
In a typical cincinnus, the neighboring two flowers are generally enantiomorphic, which leads to the pendulum symmetry of the entire cyme. While in a two-flowered Cannaceae cincinnus, the flowers develop the same chirality. In this study, we observed several abnormal cincinni of Canna indica that extended longer than their normal form, which presented a second enantiomorphic flower, thus reflecting a typical pendulum symmetry. The chirality change of the second flower was strongly associated with the position of the lateral cincinnus meristem, which determines the angle size of the cincinnus zigzag shift and may serve as a key factor controlling the formation of pendulum symmetry. We propose that alternating floral chirality and the concomitant pendulum symmetry are the essential characteristics of a typical cincinnus. Accordingly, Canna flowers with the same chirality are arranged in modified cincinni.

Abstract
Background Keeping and improving work engagement among physicians fighting COVID-19 is important to healthy medical systems. In line with the job demands-resources model, optimism was expected to positively relate with job resources, leading to higher work engagement. However, the underlying mechanism between optimism, autonomy and work engagement has not been explored. Aims To examine whether optimism has a positive impact on work engagement via autonomy among physicians fighting COVID-19 in China. Methods This study was conducted among physicians in March 2020. A convenience sample was used to recruit physicians from the Wuhan Leishenshan Hospital and Wuhan Jinyintan Hospital. One hundred and four Chinese physicians working in the COVID-19 epidemic completed a survey measuring levels of autonomy, optimism and work engagement. The PROCESS macro (model 4) was used to test hypotheses about mediation. Results This current study found that optimism was related to increased autonomy, and autonomy was related to increased work engagement. The results of the bias-corrected bootstrap method suggested the indirect effect of optimism on work engagement via autonomy (Effect = 0.16, SE = 0.08, lower level confidence interval = 0.04, upper level confidence interval = 0.37), indicating a mediated relationship, in which autonomy is one mechanism to explain the link between optimism and increased work engagement. Conclusions This study follows an observational design, with in-depth analysis of the relationship between optimism, autonomy and work engagement. When management implements strategies to improve work engagement among physicians working in the COVID-19 epidemic, the mediating impact of autonomy on the association between optimism and work engagement should be considered.

Abstract
Objective: To investigate the clinical outcomes and radiographic results of artificial cervical disc replacement (ACDR) for cervical adjacent segment disease (ASD). Methods: The clinical data of 28 patients with single-segment cervical ASD treated with ACDR in Xi 'an Honghui Hospital from December 2013 to July 2016 were retrospectively analyzed. There were 19 males and 9 females with a mean age of (46±7) years (36-63 years). Preoperative, postoperative 1 month and postoperative 24 months of clinical and radiographic outcomes were recorded and compared. The clinical outcome mainly includes Japanese orthopedic association (JOA), Neck Disability Index (NDI%), Odom score and complications. Imaging assessment mainly included range of motion (ROM) of cervical spine, surgical segment ROM, Cobb angle of surgical segment, degree of adjacent disc degeneration, heterotopic ossification, and prosthesis related image parameters. Results: In terms of clinical outcome, the average JOA score was 12.7±1.5 before surgery, 14.0±1.0 one month after surgery, 15.8±0.9 24 months after surgery, and the improvement rate of JOA was 75%±19%. The mean NDI% was 27.0%±2.8% before surgery, 20.5%±1.6% one month after surgery, and 15.3%±2.8% 24 months after surgery; the difference before and after treatment was statistically significant (F=159.101, P<0.01). Twenty patients were classified with excellent Odom score and 8 patients with good Odom score at the final follow-up. The total ROM of cervical spine, operation segment ROM, operation segment Cobb angle were all improved significantly after the operation (F=4.633, 6.063, 26.952, all P<0.05). There was a statistical difference in Miyazaki classification between adjacent discs above ACDR and below the fusion segment 24 months after surgery (μ(c)=2.12, P=0.034). The incidence of heterotopic ossification was 14.3%. The results of displacement degree of prosthesis were as follow: coronal plane (0.30±0.11) mm, sagittal plane (0.28±0.10) mm; subsidence of the prosthesis: (0.27±0.09) mm. No prosthesis loosening was observed. Conclusions: The clinical outcome of revision of cervical ASD by ACDR is satisfactory. The risk of intervertebral disc degeneration in adjacent segments is significantly lower than that of ACDF due to the presence of certain motor function postoperatively.

Abstract
AIMS Acute hepatopancreatic necrosis disease (AHPND) caused by Vibrio parahaemolyticus has emerged as a severe bacterial disease of cultured shrimp. To identify the key virulence factors, two AHPND-causing V. parahaemolyticus (VpAHPND ) strains (123 and 137) and two non-VpAHPND strains (HZ56 and ATCC 17082) were selected. METHODS AND RESULTS Challenge tests showed that the four strains exhibited different virulence towards shrimp with cumulative mortalities at 48 h postinfection (hpi) ranging from 10 to 92%. The expression of pirABVP in strain 123 and 137 was not significantly different. Genomic analysis revealed that the two VpAHPND strains contain a plasmid with the PirABVP toxins (pirABVP ) flanked by the insertion sequence (ISVal1) that has been identified in various locations of chromosomes in VpAHPND strains. The two VpAHPND strains possessed almost identical virulence factors, while ISVal1 disrupted three genes related to flagellar motility in strain 137. Phenotype assay showed that strain 123 possessed the highest growth rate and swimming motility, followed by strain 137, suggesting that the disruption of essential genes mediated by ISVal1 significantly affected the virulence level. Transcriptome analysis of two VpAHPND strains (123 and 137) further suggested that virulence genes related to the capsule, flagella and primary metabolism were highly expressed in strain 123. CONCLUSIONS Here for the first time, it is demonstrated that the virulence of VpAHPND is not only determined by the expression of pirABVP , but also is mediated by ISVal1 which affects the genes involved in flagellar motility and primary metabolism. SIGNIFICANCE AND IMPACT OF THE STUDY The genomic and transcriptomic analysis of VpAHPND strains provides valuable information on the virulence factors affecting the pathogenicity of VpAHPND.

Abstract
Percutaneous coronary intervention is a well-established technique used to treat coronary artery disease, but the risk of coronary artery in-stent restenosis following percutaneous coronary intervention is still high. Previous studies revealed that high mobility group protein B1 (HMGB1)
plays a critical role in neointima formation. In this study, we aimed to investigate the role of glycyrrhizic acid (GA), an HMGB1 inhibitor, in the process of neointima formation and the potential mechanisms. We investigated the role of GA in neointima formation through an iliac artery balloon
injury model in rabbits. Proliferation, migration, and phenotype transformation of human vascular smooth muscle cells (VSMCs) were observed. Besides, inflammation and receptor for advanced glycosylation end products (RAGE) signaling pathways were studied. The results indicate that GA attenuated
neointima formation and downregulated HMGB1 expression in injured artery in rabbits. HMGB1 promoted proliferation, migration, and phenotype transformation through the activation of RAGE signaling pathways in VSMCs, and blockade of HMGB1 by GA (1, 10, and 100 μM) could attenuate those processes
and reduce proliferation of human VSMCs. In conclusion, the HMGB1 inhibitor GA might be useful to treat proliferative vascular diseases by downregulating RAGE signaling pathways. Our results indicate a new and promising therapeutic agent for restenosis.

Abstract
Background Interpretation of the floral structure of Zingiberaceae has long concentrated on the relationships of the androecial members. It suggested that labellum is composed of two structures rather than three or five, and glands are interpreted either as gynoecial part or as androecial members. Methods Serial sections were used to observe the vasculature of normal and two-staminate flowers in Alpinia intermedia ‘shengzhen’. Floral diagrams were drawn to interpret the morphological category of the floral organs and the relationships of the androecial members. Androecial vascular bundles were associated with carpellary dorsal bundles (CDBs) and parietal bundles (PBs) in a Zingiberales phylogeny setting using ancestral state reconstruction. Results Anatomical observations demonstrate that the fertile stamen(s) incorporate parietal bundles both in normal and two-staminate flowers. The three appendages represent the three members of the outer whorl of the androecium, while the labellum represents the inner whorl of the androecium in the two-staminate flower. Reconstruction of the origin of the vascular system in the androecium suggests that the outer whorl of androecium receives its vascular supply from the CDBs, and the inner whorl of androecium receives from the PBs in both the basal banana group and the more derived ginger clade. Conclusions The present study adds to a growing body of literature suggesting that the anatomy of abnormal flowers may not provide enough evidence for elucidating the relationships of the androecial members, and help us to better understand how the vascular system is constructed during the androecial petaloidy evolution.

Abstract
OBJECTIVE To investigate the changes as well as the related mechanism in cognitive function and levels of serum β-amyloid peptide (Aβ) and brain-derived neurotrophic factor (BDNF) in stroke patients. PATIENTS AND METHODS A total of 30 patients with acute stroke treated in our hospital from June 2015 to September 2016 were selected as stroke group, while 30 volunteers during the same period were enrolled as control group. Changes in cognitive function of patients were evaluated using the Montreal Cognitive Assessment (MoCA) and mini-mental state examination (MMSE) before and after the treatment. At the same time, the concentrations of serum Aβ1-40 and BDNF were detected, and their correlations with the MMSE score were analyzed. Finally, levels of serum cyclic adenosine monophosphate (cAMP) and phosphorylated-cAMP-response element binding protein (p-CREB), and the phosphorylation level of Tau protein were detected by Western blotting. RESULTS MoCA and MMSE scores of patients in stroke group were significantly lower than those in control group (p < 0.01), and the scores were significantly higher in stroke patients after treatment than those before treatment (p < 0.01). Compared with those in control group, the serum Aβ1-40 concentration in patients in stroke group was significantly increased (p < 0.01), but the BDNF level was significantly decreased (p < 0.01). Compared with those before treatment, the serum Aβ1-40 concentration in patients was significantly decreased after treatment (p < 0.01), but the BDNF concentration was significantly increased (p < 0.01). Correlation analysis showed that the MMSE score was negatively correlated with the concentration of Aβ1-40 (r2 = 0.764, p < 0.01), but positively related to the level of BDNF (r2 = 0.827, p < 0.01). Compared with those in control group, the content of serum cAMP and p-CREB in stroke patients was significantly decreased (p < 0.01), but the expression of p-Tau was statistically increased (p < 0.01). CONCLUSIONS The cognitive function in stroke patients is impaired, with the rising content of serum Aβ1-40 and reduction of BDNF, the mechanism of which is related to the decrease of cAMP and p-CREB and the increase of p-Tau. This provides a theoretical basis for searching the new therapeutic targets and new drugs for stroke.

Abstract
The mouse is the foremost mammalian model for studying human disease and human health. However, blood sample collection from mice is challenging in research work. Tail blood collection is a popular method when a small amount of blood sample is needed. Orbital artery could be considered if a large amount of blood is needed but this blood collection method has ethical issues. Formerly, we demonstrated the feasibility and safety of blood sample collection through subclavian vein puncture in rats, and here we investigate whether this method could be used in mice. We report that this method is safe and practical for blood collection in mice. Blood collection through the subclavian vein puncture in mice can be a convenient method in daily research works.

Abstract
Blood collection with enough blood volume is essential in animal experiments. Blood collection from the tail vein of rats is popular and less stressful compared to other more aggressive methods such as retro-orbital plexus sample collection. However, this blood collection method is sometimes limited by an unsatisfactory success rate. Here, we introduce a method for blood collection through the subclavian vein puncture. The subclavian vein is located just under the clavicle and this vein is large enough to fulfill the volume requirements of blood collection. Our results show that this method is safe and applicable for blood collection sampling with the required blood volume. Blood collection through the subclavian vein puncture could serve as an alternative blood collection method in case of failed tail vein blood sampling in rats.

Abstract
Proper establishment of adaxial-abaxial polarity is essential for the development of lateral organs, while former researches were mostly focused on the polarity regulation in leaves, and little is known in stamens, especially in the asymmetric ones. Canna indica (Zingiberales: Cannaceae) is a widely cultivated ornamental plant and the representative species to study the evolutionary development of Zingiberales. The androecium of Canna indica comprises 3-4 petaloid staminodes and a fertile stamen (FS), which consists of a one-theca anther and a petaloid appendage. The partially petaloid stamen is considered as an intermediate state organ from a two-thecae stamen to a completely petaloid staminode. Using RNA-Seq, we quantified the expressions of the transcripts in anther and petaloid appendage, and detected 64,430 and 57,041 unigenes in these two organs, respectively. 4574 unigenes were down-regulated, and 3525 were up-regulated in petaloid appendage compared with those in anther. GO enrichment analysis indicated that the function of cytokinin is more related to cell differentiation in anther, while auxin is more to cell division in petaloid appendage. B- and C-class floral homeotic genes were expressed in these two androecium parts. Most of the class III HD-ZIP family members, which specify adaxial identity, were expressed lower in petaloid appendage than in anther; while KANADIs and YABBYs, which promote abaxial identity, exhibited opposite expression patterns. In situ hybridization showed that the adaxial marker gene was mainly expressed in the region between the two protrusions of the anther, while the abaxial marker was mainly expressed in petaloid appendage. We hypothesize that the adaxial-abaxial polarity participates in the distinctive anther-petaloid appendage patterning within the asymmetric FS of Canna indica.

Abstract
BACKGROUND There is a lack of culturally sensitive dietary interventions targeting Chinese Canadians despite unhealthy dietary behaviours being identified as the most important modifiable risk factor for hypertension in the Chinese population. AIMS To determine the feasibility of a culturally sensitive dietary intervention for hypertension control; to examine the potential effects of the intervention on blood pressure and health-related quality of life among Chinese Canadians in community. METHODS This study was a two-group pilot randomized controlled trial with 8 weeks follow up. Sixty self-identified Chinese Canadians, older than 45 years old and with grade one hypertension but not on antihypertensive medications were recruited in community. The control group received usual care and the intervention group received usual care plus newly developed DASHNa-CC intervention. The DASHNa-CC intervention consisted of a written manual, two classroom sessions, and one telephone booster call to provide healthy dietary and sodium reduction advice, integrated with Traditional Chinese Medicine food therapy recommendations for hypertension control. RESULTS 618 Chinese Canadians participated in blood pressure screening, and 60 eligible participants recruited. Participants were highly satisfied with the intervention and adhered to the trial protocol. The lost to follow-up rate was 5%. At 8 weeks post-randomization, those in the intervention group had greater reductions in systolic blood pressure [3.8mmHg, t (55) = -1.58, p = 0.12] and higher physical health scores [t (55) = 2.13, p = 0.04] compared to those of the control group. There were no group differences in health care utilization. CONCLUSIONS It is feasible to deliver the DASHNa-CC intervention in a Chinese Canadian community. The DASHNa-CC intervention may decrease blood pressure and improve health-related quality of life for Chinese Canadians.

Abstract
Floral organs that take on the characteristics of petals can occur in all whorls of the monocot order Zingiberales. In Canna indica, the most ornamental or 'petaloid' parts of the flowers are of androecial origin and are considered staminodes. However, the precise nature of these petaloid organs is yet to be determined. In order to gain a better understanding of the genetic basis of androecial identity, a molecular investigation of B- and C-class genes was carried out. Two MADS-box genes GLOBOSA (GLO) and AGAMOUS (AG) were isolated from young inflorescences of C. indica by 3' rapid amplification of cDNA ends polymerase chain reaction (3'-RACE PCR). Sequence characterization and phylogenetic analyses show that CiGLO and CiAG belong to the B- and C-class MADS-box gene family, respectively. CiAG is expressed in petaloid staminodes, the labellum, the fertile stamen and carpels. CiGLO is expressed in petals, petaloid staminodes, the labellum, the fertile stamen and carpels. Expression patterns in mature tissues of CiGLO and CiAG suggest that petaloid staminodes and the labellum are of androecial identity, in agreement with their position within the flower and with described Arabidopsis thaliana expression patterns. Although B- and C-class genes are important components of androecial determination, their expression patterns are not sufficient to explain the distinct morphology observed in staminodes and the fertile stamen in C. indica.

Abstract
We introduce a method to extract the photoacoustic (PA) signal from the phase time evolution of an optical coherence tomography (OCT) swept source spectral sweep. This all-optical detection is achieved in a noncontact fashion directly on the sample surface by using its specular reflection. High-speed measurement and referencing allow for close to shot noise limited phase-sensitive detection. It offers a simple way to perform OCT and PA imaging by sharing the same system components.

Abstract
We propose a scheme to compensate dynamically the intrinsic chirp of the attosecond harmonic pulses. By adding a weak second harmonic laser field to the driving laser field, the chirp compensation can be varied from the negative to the positive continuously by simply adjusting the relative time delay between the two-color pulses. Using this technique, the compensation of the negative chirp in harmonic emission is demonstrated experimentally for the first time and the nearly transform-limited attosecond pulse trains are obtained.

Abstract
The aim was to establish a method for extraction and chemical fingerprinting of extracts of Isatis indigotica roots ("Ban-Lan-Gen") and to apply the method developed to 18 Ban-Lan-Gen samples. RP-HPLC with gradient elution was performed on authentic reference standards of powdered I. indigotica roots, indigotin and indirubin purchased from the National Institute for the Control of Pharmaceutical and Biological Products (NICPBP) of China. Eighteen "Ban-Lan-Gen" samples (including the reference powdered herb) were bought from Singapore and different regions in China. Comparisons of the chromatograms showed that the samples can be divided into three groups. The chromatograms of the extracts of five samples were found to be similar to that of the extract of the authentic sample. Eight other samples had similar peaks as the authentic sample but the intensities of the peaks were generally lower, except for the peaks between retention times of 10-40 min. Peaks in these regions were more intense than those found in the extract of the authentic sample. Forty-five characteristic peaks could be found in the extracts of all the above samples. Peaks at retention times 52 and 53 min were determined to be indigotin and indirubin, respectively. The remaining four samples had similar chemical fingerprints to each other but were different from that of the authentic sample. Hierarchical clustering analysis gave similar results as the visual comparison. The RP-HPLC method developed allows simple identification and comparisons of I. indigotica roots. This is the first report of hierarchical clustering analysis of I. indigotica root.

Abstract
BACKGROUND AND PURPOSE Conventional MR imaging permits subcategorization of brain stem tumors by location and focality; however, assessment of white matter tract involvement by tumor is limited. Diffusion tensor imaging (DTI) is a promising method for visualizing white matter tract tumor involvement supratentorially. We investigated the ability of DTI to visualize and quantify white matter tract involvement in pontine tumors. METHODS AND MATERIALS DTI data (echo-planar, 1.5T) were retrospectively analyzed in 7 patients with pontine tumors (6 diffuse, 1 focal), 4 patient controls, and 5 normal volunteers. Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were calculated from the diffusion tensor in 6 regions of interest: bilateral corticospinal tracts, transverse pontine fibers, and medial lemnisci. Relationships between FA and ADC values and results of the neurologic examinations were evaluated. RESULTS The corticospinal tracts and transverse pontine fibers were affected more often than the medial lemnisci. The DTI parameters (FA and ADC) were significantly altered in all tracts of patients with pontine tumors (P < .05), compared with those values in the control groups. A marginally significant (P = .057) association was seen between the severity of cranial nerve deficit and decreased FA. CONCLUSION DTI provided superior visualization and quantification of tumor involvement in motor, sensory, and transverse pontine tracts, compared with information provided by conventional MR imaging. Thus, DTI may be a sensitive measure of tract invasion. Further prospective studies are warranted to assess the ability of DTI to delineate tumor focality and improve risk stratification in children with pontine tumors.

Abstract
To explore the effect of NF-kappa B on bcl-x gene transcription in extended drug resistance leukemia cell line HL-60/E6, drug-resistant subline HL-60/E6 was derived by intermittently exposing HL-60 cells to 6 ng/ml epirubicin. Indirect immunofluorescence was used to demonstrate the location of NF-kappa B-RelA in HL-60/E6 cells. FCM analysis and RT-PCR were used to detect the efficiency of liposome-mediated ODN transfection and the change of bcl-XL mRNA levels after 5 mumol/L phosphorothioate (PS)-derivatized antisense (AS) oligodeoxynucleotide (ODN) directed to RelA was transferred into HL-60/E6 cells. The results showed that RelA remained persistently active and located at the nuclei of HL-60/E6 cells, but in the cytoplasm of HL-60 cells, the efficiency of liposome-mediated ODN transfection was significantly higher than that of null ODN (P < 0.01 in 4 h, 6 h, 12 h, 24 h). Exposure of HL-60/E6 cells to 5 mumol/L AS-PS-ODN directed to RelA led to a maximal 40% decline of bcl-XL mRNA levels within 8 h. The inhibition rate of bcl-XL mRNA was (15 +/- 1.79)%, (28 +/- 2.34)%, (40 +/- 3.47)%, (20 +/- 1.54)%, in 4 h, 6 h, 8 h, 15 h, respectively, but it was less than 15% in control group. It was concluded that NF-kappa B was involved in regulating bcl-x transcription. It was suggested that NF-kappa B was an important factor for drug resistance in leukemia cells.

Abstract
The mechanism of chemotherapeutic drug-induced apoptosis in leukaemic cells was studied to further investigate whether Fas/FasL system was involved in apoptosis induced by chemotherapeutic drugs and assess their effects when used in combination with soluble FasL (sFasL). The expression of Fas on human leukaemic cell lines K562, HL-60 and U937 treated with daunorubicin (DNR) or cytosine arabinoside (Ara-C) was detected by using flow cytometry. The activities of sFasL, DNR and Ara-C inducing apoptosis of leukaemic cells, in the absence or presence of neutralizing anti-Fas IgG antibody, were detected by using flow cytometry and TUNEL. The results showed that flow cytometric profiles of K562, HL-60 and U937 cells treated with DNR or Ara-C failed to show any significant increase in Fas expression over 18 h (P > 0.05). Anti-Fas monoclonal antibody (IgG) could not block the apoptosis in leukaemic cells induced by DNR or Ara-C, but could block the apoptosis induced by sFasL. A role of sFasL in a cytotoxic synergistic effect when used in combination with chemotherapeutic drugs was revealed. It was concluded that chemotherapeutic drug-induced apoptosis in human leukaemic cells (UG37, HL-60) is independent of the Fas/FasL system, but combination of sFasL and drug treatment produces a synergistic cytotoxic effect on human leukaemic cells.

Abstract
In order to study the significance of flow cytometry immunophenotyping in the diagnosis of acute leukemia, CD45/SSC gating multiparameter flow cytometry (FCM) was utilized to analyze the immunophenotypes of 139 cases of acute leukemia. 139 cases of acute leukemia were enrolled in our hospital from April 1998 to April 2000. Morphological analysis and FCM immunophenotypic tests were conducted on all cases. Our results showed that CD45/SSC gating multiparameter flow cytometry immunophenotyping could reflect the origin of leukemic cells specifically. It is one of the important methods for the diagnosis of ALL, AML, and HAL. CD45/SSC gating multiparameter FCM analysis is a good technique for immunophenotyping. FCM immunophenotypic analysis can help improve the diagnosis and classification of acute leukemia, and extend the use of FCM in clinical practice.

Abstract
Kaposi's sarcoma-associated herpesvirus (KSHV)/ Human herpesvirus 8 encodes three chemokines, which are called viral macrophage inflammatory protein (vMIP)-I, -II, and -III. Here, we expressed the KSHV vMIP-I and vMIP-II proteins and analyzed their biological functions. Both vMIP-I and vMIP-II had an apparent molecular mass of 7.8 kDa and were localized to the cytoplasm in a body cavity-based lymphoma cell line BC-3, stimulated with phorbol ester. We next treated a human monocytic leukemia cell line, THP-1, with purified recombinant vMIP-I and vMIP-II, or vMIP-I and vMIP-II fused with alkaline phosphatase to study Ca(2+) signalling and in vitro chemotaxis in response to these proteins. Calcium mobilization was induced by both vMIP-I and vMIP-II. Furthermore, vMIP-I and vMIP-II induced Ca(2+) mobilization in K562 cells expressing the CC chemokine receptor 5 (CCR5), suggesting that both may be agonistic for CCR5. Additionally, vMIP-I induced Ca(2+) mobilization through the intermediary of CCR8. These viral MIPs were also capable of chemotactically activating the THP-1 cells. These results imply that vMIP-I and vMIP-II may play important roles in the propagation of KS and primary effusion lymphoma by inducing the chemotaxis of CCR5-expressing monocytes.

Abstract
OBJECTIVE To investigate the expression and significance of human telomerase reverse transcriptase (hTERT) gene in cord blood hematopoietic stem cells. METHODS Using in situ hybridization techniques, we detect the expression of hTERT gene in cord blood hematopoietic stem cells in different condition during different culture time. RESULTS hTERT gene was lowly expressed in freshly isolated cord blood CD34+ cells; the positive rate was 13%. It could be increased in 5-7 days when the cells were cultured in vitro, especially in the presence of stem cell factor, interleukin-3(IL-3), IL-6 and Flt-3 Ligand together; the positive rate reached 48%. Transform growth factor-beta 1 and all-trans retinoic acid could repress hTERT gene. CONCLUSION hTERT gene was lowly expressed in the cord blood CD34+ cells; it could be upregulated in the culture in vitro along with optimal cytokines, but was downregulated by negative regulator and induction differentiation.

Abstract
The bioactivities of culture supernatants from retroviral packaging cells carrying the mouse Fas ligand (mFasL) gene was investigated. FasLcDNA was cloned into PLXIN with an internal ribosome entry site to link two cistrons through gene recombination technology, PLXIN and the recombinant vector PLFIN were separately transfected into PA317 retrovirus packing cell line by lipofectamine 2000, and the resistant clones were selected with G418 selective medium. The integration of genome DNA was assayed by genomic DNA PCR. NIH3T3 cells were transduced by the culture supernatants from PA317 carrying the mFasLcDNA gene, and were selected with G418 selective medium, so as to select the PLFIN-PA317 clone capable of producing higher titer of supernatants. The levels of mFasL protein on NIH3T3 cells membrane were assayed by flow cytometry (FCM). The biological activity of mFasL on NIH3T3 cells membrane was investigated by the inducing apoptosis of Fas+ Yac-1 cells co-cultured with NIH3T3 cells expressing Fas ligand. To explore the direct mFasL cytotoxicity of culture supernatants from retroviral packaging cells carrying the mFasL gene, the culture supernatants from PLFIN-PA317 and PLXIN-PA317 were separately co-cultured with Yac-1 cells in parallel. The recombinant PLFIN was successfully constructed. The highest titer of supernatants from twelve resistant clones was 8.5 x 10(5) colony-forming-unit (CFU)/ml. The NIH3T3 cells transfected by above supernatants had a higher level of mFasL (53.81 +/- 6.9%), and significantly induced the apoptosis of Fas+ Yac-1 cells (56.78 +/- 4.5%), as both were cocultured for 5 h at 1:1 ratio, whereas it is 7.08 +/- 3.4% in control group (P < 0.01). Supernatant from PLFIN-PA317 could also directly induce the apoptosis of Yac-1 within 5 h of incubation. Thus, the culture supernatants from PLFIN-PA317 possessed both infectivity and cytotoxicity of mFasL.

Abstract
Biology and life table parameters of Brennandania lambi (Krczal) were studied at different temperatures while feeding on white mushroom (Agaricus bisporus) mycelium cultured on mushroom compost. The duration of egg and larva development, preoviposition and oviposition period, female longevity, and the time to 50% mortality declined as temperature increased from 16 to 28 degrees C. The threshold temperature of development (female) was 9 degrees C and the thermal constant for completion of development (female) was 195 day-degrees. At 16, 20. 24 and 28 degrees C, the total fecundity (eggs/female) was 71, 67, 66 and 57, respectively and the daily fecundity rate (eggs/female/day) was 5.6, 8.7, 8.7 and 9.1, respectively. The sex ratio (female/male) ranged from 1.9 to 2.1 at 16-28 degrees C. At 16, 20, 24 and 28 degrees C, the intrinsic rate of natural increase (rm) was 0.11, 0.18, 0.22 and 0.27, respectively, and the population doubling time was 6.1. 3.9. 3.2 and 2.5 days, respectively. All life stages of the mite died when exposed to 35 degrees C constant temperature for 24h. or to 32 degrees C constant temperature for 12 days or to 31-35 degrees C (average 32.9 degrees C) ambient temperature for 4 days. Brennandania lambi completed development only when fed on Ag. bisporus mycelium growing on mushroom compost. It could not survive on mushroom mycelia of Auricularia auricula. Au. polytricha, Ganoderma lucidum, Hericium erinaceus, Lentinus edodes, Pleurotus ostreatus, P. sajor-caju and Tremella juciformis.

Abstract
A computed tomography (CT) imaging technique called variable resolution x-ray (VRX) detection provides variable image resolution ranging from that of clinical body scanning (1 cy/mm) to that of microscopy (100 cy/mm). In this paper, an experimental VRX CT scanner based on a rotating subject table and an angulated storage phosphor screen detector is described and tested. The measured projection resolution of the scanner is > or = 20 lp/mm. Using this scanner, 4.8-s CT scans are made of specimens of human extremities and of in vivo hamsters. In addition, the system's projected spatial resolution is calculated to exceed 100 cy/mm for a future on-line CT scanner incorporating smaller focal spots (0.1 mm) than those currently used and a 1008-channel VRX detector with 0.6-mm cell spacing.
