Abstract
PURPOSE This research was performed to evaluate the relationship between hypertension (HTN) and abdominal obesity index in patients with type 2 diabetes mellitus (T2DM). METHODS Totally 1657 participants with T2DM (mean age 54 ± 12 years; 38.02% female) were enrolled. They were divided into the groups of HTN (n = 775) and non-HTN (n = 882). Anthropometric and biochemical indicators were measured and collected. A bioelectrical impedance analyzer was used to measure visceral and subcutaneous fat areas. RESULTS Compared with the HTN group, the non-HTN group had a lower level of Chinese visceral adiposity index (CVAI) (p < 0.001). Meanwhile, among tertiles of CVAI, as CVAI increased, the proportion of patients with HTN increased, which was 33.51%, 44.30%, and 62.50%, respectively. CVAI was shown to have a significant positive correlation with HTN. (r = 0.258, p < 0.001). CVAI was independently related to an elevated risk of HTN by binary logistic regression analyses, and the OR was (95% CI) 1.013 (1.010-1.016, p < 0.001) after adjustment. The area under the receiver operating characteristic curve (AUC) of CVAI predicted HTN in T2DM patients was greater than those of other abdominal obesity indices (p < 0.001). CONCLUSION We found that CVAI was highly positively correlated with HTN in T2DM. Compared with other indices of abdominal obesity, such as WC, BMI, WHR, VAI, and LAP, the CVAI showed superior discriminative ability in T2DM complicated with HTN. Therefore, more attention should be paid to CVAI in T2DM.

Abstract
Sovleplenib (HMPL-523) is a selective spleen tyrosine kinase (Syk) inhibitor with antitumor activity in preclinical models of B-cell malignancy. We conducted a dose-escalation and dose-expansion phase I study of sovleplenib in patients with relapsed/refractory mature Bcell tumors. Dose escalation followed a 3+3 design; patients received oral sovleplenib (200-800 mg once daily [q.d.] or 200 mg twice daily [b.i.d.], 28-day cycles). During dose expansion, patients were enrolled into four cohorts per lymphoma classification and treated at the recommended phase 2 dose (RP2D). Overall, 134 Chinese patients were enrolled (dose escalation, n=27; dose expansion, n=107). Five patients experienced dose-limiting toxicities: one each of amylase increased (200 mg q.d.), febrile neutropenia (800 mg q.d), renal failure (800 mg q.d.), hyperuricemia and blood creatine phosphokinase increased (200 mg b.i.d.) and blood bilirubin increased and pneumonia (200 mg b.i.d.). RP2D was determined as 600 mg (>65 kg) or 400 mg (≤65 kg) q.d. The primary efficacy end point of independent review committee-assessed objective response rate in indolent B-cell lymphoma was 50.8% (95% CI, 37.5-64.1) in 59 evaluable patients at RP2D (follicular lymphoma: 60.5%, marginal zone lymphoma: 28.6%, lymphoplasmacytic lymphoma/Waldenström macroglobulinemia, 0%). The most common (≥10% patients) grade ≥3 treatment-related adverse events in the doseexpansion phase were decreased neutrophil count (29.9%), pneumonia (12.1%) and decreased white blood cell count (11.2%). Pharmacokinetic exposures increased doseproportionally with ascending dose levels from 200-800 mg, without observed saturation. Sovleplenib showed antitumor activity in relapsed/refractory B-cell lymphoma with acceptable safety. Further studies are warranted.

Abstract
Spleen tyrosine kinase (Syk) is an intracellular tyrosine kinase involved in the signal transduction in immune cells mainly. Its aberrant regulation is associated with diversified allergic disorders, autoimmune diseases and B cell malignancies. Therefore, inhibition of Syk is considered a reasonable approach to treat autoimmune/inflammatory diseases and B cell malignancies. Here we described the preclinical characterization of sovleplenib, a novel, highly potent and selective, oral Syk inhibitor, in several rodent autoimmune disease models. Sovleplenib potently inhibited Syk activity in a recombinant enzymatic assay and Syk-dependent cellular functions in various immune cell lines and human whole blood in vitro. Furthermore, sovleplenib, by oral administration, demonstrated strong in vivo efficacies in murine models of immune thrombocytopenia (ITP), autoimmune hemolytic anemia (AIHA), and chronic graft-versus-host disease (cGVHD), and a rat model of collagen induced arthritis (CIA) respectively, in a dose-dependent manner. Collectively, these results clearly supported sovleplenib as a therapeutic agent in the treatment of autoimmune diseases. Sovleplenib is being globally developed for ITP (Phase III, NCT05029635, Phase Ib/II, NCT03951623), wAIHA (Phase II/III, NCT05535933) and B-cell lymphoma (Phase I, NCT02857998, NCT03779113). SIGNIFICANCE STATEMENT: Syk is a key mediator of signaling pathways downstream of a wide array of receptors important for immune functions, including the B cell receptor, immunoglobulin receptors bearing Fc receptors. Inhibition of Syk could provide a novel therapeutic approach for autoimmune diseases and hematologic malignancies. The manuscript describes the preclinical pharmacology characterization of sovleplenib, a novel Syk inhibitor, in enzymatic and cellular assays in vitro and several murine autoimmune disease models in vivo.

Abstract
Abstract
Introduction: Bruton’s tyrosine kinase (BTK), a member of the Tec family, plays a crucial role in signaling through B-cell receptor (BCR). BTK inhibition blocks BCR signals and prevents B-cell activation and growth. First-generation BTK inhibitors such as ibrutinib covalently binds to a cysteine residue (C481) of BTK. Their most frequent acquired resistance is the development of a serine mutation in the binding site (C481S). Next generation BTK inhibitors such as LOXO-305 and ARQ 531 are being developed to overcome this resistance to first-generation inhibitors.
Methods: HMPL-760 was tested in biochemical assays using recombinant human wild type (WT) and C481S mutant BTKs. Its selectivity was carried out using Eurofins Cerep KinaseProfilerTM panel. Cellular activity of HMPL-760 was evaluated in HEK293 cells stably transfected with BTKWT or BTKC481S, and other tumor cell lines, which are either human diffuse large B cell lymphoma (DLBCL) or mantle cell lymphoma (MCL) cell lines. The in vivo antitumor activity and PKPD correlation of HMPL-760 was studied in HBL-1 xenograft mouse models bearing BTKWT or BTKC481S respectively.
Results: In biochemical assays, HMPL-760 strongly inhibits BTK kinase activities towards wild-type BTK (BTKWT) and C481S mutant (BTKC481S), and binds to BTK in a reversible way. HMPL-760 demonstrates high selectivity in a panel containing 413 kinases. In cellular assays, HMPL-760 displays strong anti-proliferative activities in B-cell lymphoma cells (TMD-8, OCI-LY10, REC-1, HBL-1 and HBL-1-BTKC481S) harboring either BTKWT or BTKC481S (GI50: 0.0015-0.046 μM). In human whole blood assay, HMPL-760 inhibits activation of B-cells at nanomolar concentrations measured by inhibition of immunoglobulin-induced CD69 expression in CD19+cells. HMPL-760 shows ≥ 10-fold inhibitory potency than ARQ 531 in both BTKWT and BTKC481S cells, and ~3-fold higher inhibitory potency than that of LOXO-305 in BTKC481S cells. In cellular assay by detecting p-BTK after compound washout, HMPL-760 maintains a longer duration of target inhibition than LOXO-305 in both BTK wild type (HBL-1) and BTK mutant (HBL-1-BTKC481S) cell lines. HMPL-760 displays dose-dependent antitumor efficacy in multiple human B cell lymphoma xenograft models in mice when orally administered at 3~50 mg/kg once daily. Complete tumor regression occurs in most of the tested models at the high dose levels. HMPL-760 shows much stronger antitumor efficacy than LOXO-305 and ARQ 531 at similar dose level, which may be associated with HMPL-760’s higher drug exposures and more sustainable inhibition on BTK phosphorylation in the tumor tissues.
Conclusion: HMPL-760 is a reversible, selective, highly potent, BTK inhibitor targeting both BTKWT and BTKC481S. The first-in-human Phase 1 clinical trials of HMPL-760 are under way in patients with r/r B-NHL (NCT05190068, NCT05176691).

Abstract
Abstract
Background: Mutations in isocitrate dehydrogenase (IDH) 1/2 are frequently identified in various cancers, such as AML, cholangiocarcinoma, chondrosarcoma and glioma. Mutant IDHs (mIDHs) cause accumulated 2-HG, leading to blockage of cell differentiation, thereby inducing malignant transformation. Rare cases were identified carrying co-existing mutations in IDH1 and IDH2. mIDH isoform switching, from mutant IDH1 to mutant IDH2 and vice versa, have been reported as a mechanism of acquired resistance to IDH inhibition in AML and cholangiocarcinoma. Thus, simultaneous inhibition on both mIDH1 and mIDH2 may be a promising strategy to overcome resistance and improve clinical efficacy. HMPL-306, a dual inhibitor of mIDH1/mIDH2, developed by HUTCHMED, is being evaluated in clinical trials.
Methods: The inhibition of HMPL-306 on IDH enzymes, including mutant and wild type, was determined by fluorescence-based assay. The selectivity of HMPL-306 was evaluated in 322 kinases (SelectScreenTM) and 88 proteins (Cerep). For cellular activities of HMPL-306, 2-HG production and differentiation were detected in cells harboring mIDH. Human tumor xenograft models carrying IDH1 or 2 mutations were established for evaluating mIDH inhibition by detecting 2-HG in plasma and tumor, and anti-tumor efficacies.
Results: HMPL-306 inhibited mutant IDH enzyme activities including IDH1R132H, IDH2R140Q and IDH2R172K, while showed weaker inhibition on IDH1/2 wild type enzymes. HMPL-306 had a superior selectivity profile in a kinase panel and a safety panel, while enasidenib, an approved mIDH2 inhibitor, inhibited Adenosine-A3 with IC50 of 12 nM. In cellular assays, HMPL-306 displayed comparable activities to enasidenib and ivosidenib (approved mIDH1 inhibitor) and suppressed 2-HG through inhibition of mIDH1 or mIDH2 at similar level, indicating an equal potency against mIDH1 and 2. Moreover, in both mIDH1/2 cells, HMPL-306 reduced the levels of histone methylation, and promoted hemoglobin γ and Kruppel1 gene expression, which led to differentiation from immature malignant cells to mature normal cells. Oral administration of HMPL-306 remarkably decreased 2-HG level in plasma and tumor tissues in xenograft models carrying mIDH1 or mIDH2 and the inhibition is more potent and durable than either ivosidenib or enasidenib at the same dose. Pharmacokinetics (PK) study in rodents showed high exposures of HMPL-306 in brain and cerebrospinal fluid, a desirable feature for glioma therapy. Combination treatment of HMPL-306 and azacitidine synergized in releasing the differentiation block in mIDH AML cells. HMPL-306 also significantly improved in vivo anti-tumor efficacy of chemotherapy drugs in solid tumor models with mIDH1/2.
Conclusion: HMPL-306 is a potent, dual inhibitor of IDH1/2 mutation. The strong activity and favorable PK profiles support further clinical evaluation.

Abstract
Goose astrovirus (GoAstV) is a novel avastrovirus that typically causes gosling gout and results in 2 to 20% mortality. GoAstV capsid protein is the sole structural protein, which is responsible for viral attachment, assembly, maturation as well as eliciting host antibodies. However, the epitopes within capsid protein have not been well studied. In this study, a monoclonal antibody, named 1D7, was generated against GoAstV capsid protein by hybridoma technology. Western blot results showed that this MAb could react with recombinant capsid protein expressed in E. coli. Also, it recognized the precursor of capsid protein, VP90 and VP70, in GoAstV-infected cells. Besides, excellent specificity of MAb 1D7 was further demonstrated in indirect immunofluorescence assay and immunohistochemical analysis. Epitope mapping results revealed that MAb 1D7 recognized the epitope 33QKVY 36 within Cap protein. Sequence alignment indicated that 33QKVY 36 is a conserved epitope among the isolates of goose astrovirus type 2 (GoAstV-2), suggesting the potential for its use in GoAstV-2 specific diagnostic assay. These findings may provide some insight into a function of the GoAstV capsid protein and further contribute to the development of diagnostic methods for GoAstV infection.

Abstract
BACKGROUND Heilongjiang province is the main cattle-producing area in China, and molecular epidemiological studies of bovine viral diarrhea viruses (BVDV) in cattle have not been performed in the province. AIMS The objective of this research was to determine the genetic and clinical characteristics of BVDV in cattle. METHODS Fifty-three BVDV-positive clinical samples were collected from 22 cattle farms in Heilongjiang, and the 5´-untranslated region (5´-UTR) was used to carry out a phylogenetic analysis of the viruses. RESULTS The similarity of the 5´-UTR sequences among these BVDVs was 84.2%-100%, and the phylogenetic analysis showed that all viruses belong to the BVDV-1 species, which is classified into five subtypes: BVDV-1b (47.17%, n=25), 1c (15.09%, n=8), 1d (16.98%, n=9), 1 m (3.77%, n=2), and 1o (16.98%, n=9). The statistical results showed that the BVDV-1b subtype had a positive correlation with gastrointestinal disease (P<0.05; 95% CI: 1.19 to 3.34). There were up to three or four BVDV-1 subtypes in some dairy cattle farms, but farms with a single subtype were prevalent (5/10). CONCLUSION BVDV-1b is predominant in cattle herds of Heilongjiang province, China, and shows a positive correlation with gastrointestinal disease. BVDV-1o was found for the first time in Chinese cattle, which increased the complex distribution of BVDV-1 subtypes in cattle herds of China.

Abstract
Phosphoinositide 3-kinases, delta (PI3Kδ) and gamma (PI3Kγ) are enriched in immune cells and regulate the development and function of innate and adaptive immunity. Dual PI3Kδγ inhibitors are considered high value targets for their potential to treat a variety of immune-mediated diseases, but their discovery has been challenging. Here we describe the preclinical pharmacology of HM5023507, an orally active dual inhibitor of δγ isoforms in immune signaling. HM5023507 inhibited PI3Kδ and PI3Kγ isoforms with greater than 100-fold selectivity against PI3Kα and PI3Kβ in recombinant enzymatic assays and in primary human immune cells with an exquisite selectivity against other targets. HM5023507 attenuated the PI3Kδ/γ signaling in human basophils (IC50: 42/340 nmol/L; selectivity ratio ~1:8). HM5023507 attenuated the activation and function of human B and T cells, Th17 differentiation of CD4 T cells in the blood of healthy donors and rheumatoid arthritis patients, and cytokine and IgG production in human T and B cell cocultures, in vitro. Orally dosed HM5023507 attenuated PI3K δ/γ-mediated immune signaling in the rat in a dose-related manner. In addition, HM5023507 inhibited semiestablished collagen-induced arthritic inflammation in the rats (ED50 of 0.25mg/kg, p.o. BID or 0.5 mg/kg, QD, AUC: 1422 ng/mL*h), improved histopathology- and micro-computed tomography (µCT)-based indices of joint damage, bone destruction, and attenuated the levels of anti-collagen antibody, with an overall anti-inflammatory profile matching that of a TNFα neutralizing antibody. The PI3K δγ inhibitory profile of HM5023507 and its selectivity make it a useful tool to further delineate immunobiology of dual PI3K δγ targeting.

Abstract
Background: Previously, we showed that the Zinc finger-containing transcription factor ZNF424 inhibits p21 transcription, which has been widely associated with various cancers. However, because the roles of ZNF424 in tumorigenesis have not been characterized, we correlated ZNF424 expression with tumorigenesis in lung cancer. Results: The present immunohistochemical analyses show significantly lower ZNF424 expression levels in 43 of 60 lung cancer tissues compared with adjacent tissues. Moreover, flow cytometry assays indicated that overexpression of ZNF424 induces apoptosis in A549 human lung carcinoma cells, and overexpression of ZNF424 significantly increases numbers of G1 phase cells and decreases numbers of S phase cells, suggesting that ZNF424 inhibits proliferation. Western Blot analyses show that overexpression of ZNF424 decreases protein expression levels of the mitogen-activated protein kinase (MAPK) signaling proteins P-P38 and P-ERK in A549 cells. Conclusion: These are the first data to associate ZNF424 with tumorigenesis and demonstrate an inhibitory role in lung cancer, indicating the potential of ZNF424 expression as a diagnostic marker of lung tumorigenesis.

Abstract
Background: Four-and-a-half LIM domains protein 1 (FHL1) mutations are associated with human myopathies. However, the function of this protein in skeletal development remains unclear. Methods: Whole-mount in situ hybridization and embryo immunostaining were performed. Results: Zebrafish Fhl1A is the homologue of human FHL1. We showed that fhl1A knockdown causes defective skeletal muscle development, while injection with fhl1A mRNA largely recovered the muscle development in these fhl1A morphants. We also demonstrated that fhl1A knockdown decreases the number of satellite cells. This decrease in satellite cells and the emergence of skeletal muscle abnormalities were associated with alterations in the gene expression of myoD, pax7, mef2ca and skMLCK. We also demonstrated that fhl1A expression and retinoic acid (RA) signalling caused similar skeletal muscle development phenotypes. Moreover, when treated with exogenous RA, endogenous fhl1A expression in skeletal muscles was robust. When treated with DEAB, an RA signalling inhibitor which inhibits the activity of retinaldehyde dehydrogenase, fhl1A was downregulated. Conclusion: fhl1A functions as an activator in regulating the number of satellite cells and in skeletal muscle development. The role of fhl1A in skeletal myogenesis is regulated by RA signaling.

Abstract
An electronic density model was developed and used to identify a novel pyrrolotriazinone replacement for a quinazolinone, a commonly used moiety to impart selectivity in inhibitors for PI3Kγ and PI3Kδ. Guided by molecular docking, this new specificity piece was then linked to the hinge-binding region of the inhibitor using a novel cyclic moiety. Further structure-activity relationship optimization around the hinge region led to the discovery of candidate 26, a highly potent and selective PI3Kγ-PI3Kδ dual inhibitor with favorable drug metabolism and pharmacokinetic properties in preclinical species.

Abstract
Introduction The neural stem cell (NSC) niche is a highly complex cellular and biochemical milieu supporting proliferating NSCs and neural progenitor cells (NPCs) with close apposition to the vasculature, primarily comprised of endothelial cells (ECs). Current in vitro models of the niche incorporate EC-derived factors, but do not reflect the physiologically relevant hemodynamic state of the ECs or the spatial resolution observed between cells within the niche. Methods In this work, we developed a novel in vitro model of the niche that (1) incorporates ECs cultured with fluid shear stress and (2) fosters paracrine cytokine gradients between ECs and NSCs in a spatiotemporal configuration mimicking the cytoarchitecture of the subventricular niche. A modified cone and plate viscometer was used to generate a shear stress of 10 dynes cm-2 for ECs cultured on a membrane, while statically cultured NPCs are 10 or 1000 μm below the ECs. Results NPCs cultured within 10 μm of dynamic ECs exhibit increased PSA-NCAM+ and OLIG2+ cells compared to progenitors in all other culture regimes and the hemodynamic EC phenotype results in distinct progeny phenotypes. This co-culture regime yields greater release of pro-neurogenic factors, suggesting a potential mechanism for the observed progenitor maturation. Conclusions Based on these results, models incorporating ECs exposed to shear stress allow for paracrine signaling gradients and regulate NPC lineage progression with appropriate niche spatial resolution occurring at 10 μm. This model could be used to evaluate cellular or pharmacological interactions within the healthy, diseased, or aged brain.

Abstract
UNLABELLED Secreted frizzled-related protein 5 (sFRP5) level in bone marrow environment is inversely correlated with bone formation markers, suggesting that it decreases bone mass by inhibiting bone formation. Besides, it functions in a local fashion when regulating bone metabolism. sFRP5 may be a target when developing anti-osteoporotic agents. INTRODUCTION The purpose of the study is to investigate the relationship between bone marrow sFRP5 level and bone turnover state. METHODS Eighty-three total knee arthroplasty patients were enrolled in this study. Data were collected prospectively and reviewed retrospectively. Lumbar spine and femoral neck bone mineral density (BMD), marrow adipose tissue (MAT) sFRP5 messenger RNA (mRNA) expression level, sFRP5 concentrations in marrow fluid and serum, concentrations of bone formation and resorption markers were measured for each participant. RESULTS Marrow fluid sFRP5 concentration was positively correlated with both MAT sFRP5 expression (p = 0.040) and serum sFRP5 concentration (p = 0.043). Significantly positive correlation existed between MAT sFRP5 expression level and BMD (p < 0.05). Marrow fluid sFRP5 concentration had a moderate but not significant positive association with BMD. MAT sFRP5 was negatively related to serum bone formation markers including N-terminal propeptide of type 1 procollagen (P1NP) (p = 0.011), osteocalcin (OC), and alkaline phosphatase (ALP). Marrow fluid and serum sFRP5 concentrations also had mild negative correlations with bone formation markers but reached no significance. There was no significant correlation between bone resorption marker β-crosslaps (β-CTX) and sFRP5. The mRNA expression level of MAT sFRP5 was positively related with those of MAT leptin, peroxisome proliferator-activated receptor-γ (PPARγ), and adiponectin, and its correlation with leptin was statistically significant (p = 0.026). CONCLUSIONS Bone marrow sFRP5 level is closely correlated with BMD and bone formation markers. sFRP5 may be a potential negative regulator of bone mass by inhibiting bone formation. It may exert its effects on bone metabolism in a paracrine, rather than endocrine manner.

Abstract
Purpose: We determined whether reperfusion damage was sufficient to allow extravasation of a large molecular weight contrast agent into infarcted pig myocardium. Material and Methods: Five pig hearts were subjected to in situ occlusion of the left anterior descending coronary artery (2 h) followed by reperfusion (1 h). The hearts were excised and perfused in the Langendorff mode for ex vivo MR imaging. Polylysine-Gd-DTPA (50,000 Da) and Gd-DTPA (500-700 Da) were injected into the aorta (alternately) and followed by measurements of T1 relaxation and mean transit time (MTT). Results: In the normal myocardium, MTT of Gd-DTPA (56.8±23.2 s) was significantly ( p=0.02) longer than that of polylysine-Gd-DTPA (29.0±7 s). However, both normal and infarcted myocardium showed similar MTT (29.0±7.0 vs. 28.0±5.0 s, p>0.05) when using polylysine-Gd-DTPA. Conclusion: The results indicate that the permeability of capillaries to polylysine-Gd-DTPA was not significantly higher in infarcted regions of the myocardium compared to normal tissue. However, infarcted myocardium displayed an increased permeability to the small molecular weight Gd-DTPA. We conclude that microvascular damage may not be sufficient to allow the extravasation of polylysine-Gd-DTPA in infarcted myocardium.

Abstract
The human Hole gene (hHole) encodes a six-transmembrane protein with 319- amino acids. Our previous study showed that hHole was strongly expressed in adult heart and may act as a suppressor of extracellular signal-regulated kinases (ERKs), overactivation of which contributed to pathological cardiac hypertrophy. In this study, it was observed that Hole expression was up-regulated in murine hypertrophic hearts. In a cardiac specific transgenic mouse model, it was observed that overexpression of hHole specifically in heart attenuated cardiac hypertrophy and fibrosis induced by isoproterenol (ISO), with blunted transcriptions of ERK1/2, total ERK1/2 proteins and phosphorylated ERK1/2 (p-ERK1/2) levels. Furthermore, overexpression of hHole in mice by hydrodynamic tail-vein injection with hHole plamids also inhibited cardiac hypertrophy induced by ISO. Our work identified hHole as a novel repressor of cardiac hypertrophy, and provided new insights into the possible target for the prevention or treatment of cardiac diseases.

Abstract
Branchiostoma belcheri Gray is a second-class, nationally protected protochordate in China. We developed 10 novel polymorphic sites in B. belcheri, which were examined using a population of 30 wild individuals from Xiamen, China. The polymorphism information content ranged between 0.141 and 0.681, and the number of alleles varied from 2 to 5. The expected and observed heterozygosities varied between 0.1528 and 0.6920, and between 0.1429 and 0.5000, respectively. These novel microsatellite markers will facilitate the genetic analysis and protection of wild B. belcheri individuals, and the possible re-stocking of the species in the long-term.

Abstract
Curry fish (Stichopus horrens) is a tropical holothurian species and is widely distributed in the India-West Pacific. In the present study, 9 polymorphic microsatellite loci were isolated and characterized for S. horrens. These loci were tested in 30 individuals from Hainan Island in China. The number of alleles ranged from 2 to 5. The polymorphism information content ranged from 0.348-0.584. The levels of observed and expected heterozygosities varied from 0.1500-0.8000 and from 0.2014-0.5000, respectively. Most loci were in Hardy-Weinberg equilibrium, except HCS1-27 and HCS2-7, after sequential Bonferroni's correction, and no significant linkage disequilibrium was detected for any pairwise combination of loci. These polymorphic microsatellite loci will be useful for studying population structure and conservation strategy design for S. horrens.

Abstract
Thirteen new polymorphic microsatellite markers in Fenneropenaeus penicillatus were isolated and characterized. The polymorphism of the thirteen microsatellite markers was tested by 30 individuals from Lianjiang, China. It showed that the number of al-leles per locus ranged from 3 to 6 and the Polymorphism Information Content (PIC) was from 0.324 to 0.706. The observed and expected heterozygosities were 0.3217-0.8023 and 0.1977-0.6783, respectively. Only one loci (LJ-19) deviated significantly from Hardy-Weinberg equilibrium (HWE) (P < 0.00385) after Bonferroni correction, while the other twelve markers were in HWE after Bonferroni correction (P > 0.00385). The thirteen polymorphic microsatellite markers could pro-vide more genetic data for further research on cultivation and recovery of F. penicillatus.

Abstract
Lunella coronata granulata, from the family Turbini-dae, is an economically important species. The first set of 10 poly-morphic microsatellite loci was screened from L. coronata granulata, and 30 individuals were used to analyze the degree of polymorphism in these loci. The level of observed and expected heterozygosity was 0.0667-0.7333 and 0.0644-0.6628, respectively. The polymorphism information content varied from 0.305 to 0.559. Eight loci were in Hardy-Weinberg equilibrium (HWE) (P > 0.05), while two loci devi-ated significantly from the HWE after Bonferroni's correction (P < 0.005). The isolated microsatellite loci can be utilized in studies of population genetic analysis and they provide important genetic mark-ers for construction of genetic linkage maps and genetic breeding of L. coronata granulata resources.

Abstract
The pen shell, Atrina vexillum Born, is an edible shellfish that is widely consumed in the Asia-Pacific region. In this study, 11 polymorphic microsatellite loci were isolated from A. vexillum, and 30 wild individuals were used to evaluate the degree of polymorphism of these markers. The number of alleles per locus ranged from 3 to 8. The polymorphism information content varied from 0.199 to 0.831. The observed and expected heterozygosities were 0.1000-0.8667 and 0.1244-0.8356, respectively. Two loci deviated significantly from the Hardy-Weinberg equilibrium (HWE) after a Bonferroni correction, while the other nine loci were at HWE. These microsatellite loci will be useful in further studies on population genetic analyses, and will provide important genetic data for the conservation and recovery of A. vexillum.

Abstract
The marbled rockfish, Sebastiscus marmoratus, is an important commercially near-shore fish that inhabits the beach rocky bottom from Japan to the South China Sea. Eleven polymorphic microsatellite loci were developed from S. marmoratus and were used to identify polymorphisms in 30 samples from a wild population. The allele locus number ranged from 2 to 7. Polymorphism data content ranged from 0.032 to 0.751. The observed and expected heterozygosity levels were 0.0333-0.9667 and 0.0328-0.7675, respectively. Two loci, Smd1-112 and Smd2-80, deviated from Hardy-Weinberg equilibrium. These polymorphic microsatellite markers will facilitate further studies of genetic diversity and genetic differentiation of S. marmoratus.

Abstract
Holothuria leucospilota is a tropical holothurian species that is widely distributed in the tropical and sub-tropical India-Western Pacific Region. Eight polymorphic microsatellite loci were developed from H. leucospilota by using the protocol fast isolation by amplified fragment length polymorphism of sequences containing repeats and tested in 30 individuals from Hainan Island in China. The number of alleles was 2-6 and polymorphism information content ranged from 0.371-0.694. The levels of expected and observed heterozygosities varied from 0.3913-0.6701 and from 0.1154-0.7000, respectively. No significant linkage disequilibrium was detected for any pairwise combination of loci. Only loci YZHS1-42 deviated from Hardy-Weinberg equilibrium. These polymorphic microsatellite loci may be useful for germplasm conservation of H. leucospilota.

Abstract
The rabbitfish Siganus fuscescens is an economically valuable species that is widely distributed throughout the estuaries, intertidal, and offshore coasts of the Indo-Pacific and eastern Mediterranean. Ten novel microsatellite loci from the genome of S. fuscescens were developed using the fast isolation protocol with amplified fragment length polymorphism of sequences containing repeats. Polymorphisms in these 10 microsatellite markers were determined from 32 wild individuals. The number of alleles per locus and the polymorphism information content ranged from 2 to 5 and from 0.059 to 0.668, respectively. The observed and expected heterozygosities varied from 0.063 to 0.781 and from 0.062 to 0.731, respectively. Although 1 locus (LZY-X7, P < 0.005) showed significant deviation from the Hardy-Weinberg equilibrium, no deviations were detected in the other 9 loci. These microsatellite loci may be useful for further population genetic studies, conservation studies, population structure assessment, and linkage map construction of S. fuscescens.

Abstract
Fenneropenaeus penicillatus, with high protein and low fat, is a commercially important aquatic product in China. Microsatellite loci were developed according to the protocol of fast isolation by amplified fragment length polymorphism of sequences containing repeats. Eight new polymorphic microsatellite markers for F. penicillatus were identified, and 32 wild individuals were used to evaluate the degree of polymorphism of these markers. The polymorphism information content ranged from 0.2703 to 0.7598, and the number of alleles per locus varied from 3 to 6. The observed and expected heterozygosities were 0.1613-0.5556 and 0.2347-0.7387, respectively. No significant deviations from Hardy-Weinberg equilibrium (P > 0.00625) were detected. These polymorphic microsatellite loci will be useful to study the genetic diversity and population structure of F. penicillatus.

Abstract
The present study was designed to investigate the cardioprotective effects of betaine on acute myocardial ischemia induced experimentally in rats focusing on regulation of signal transducer and activator of transcription 3 (STAT3) and apoptotic pathways as the potential mechanism underlying the drug effect. Male Sprague Dawley rats were treated with betaine (100, 200, and 400 mg/kg) orally for 40 days. Acute myocardial ischemic injury was induced in rats by subcutaneous injection of isoproterenol (85 mg/kg), for two consecutive days. Serum cardiac marker enzyme, histopathological variables and expression of protein levels were analyzed. Oral administration of betaine (200 and 400 mg/kg) significantly reduced the level of cardiac marker enzyme in the serum and prevented left ventricular remodeling. Western blot analysis showed that isoproterenol-induced phosphorylation of STAT3 was maintained or further enhanced by betaine treatment in myocardium. Furthermore, betaine (200 and 400 mg/kg) treatment increased the ventricular expression of Bcl-2 and reduced the level of Bax, therefore causing a significant increase in the ratio of Bcl-2/Bax. The protective role of betaine on myocardial damage was further confirmed by histopathological examination. In summary, our results showed that betaine pretreatment attenuated isoproterenol-induced acute myocardial ischemia via the regulation of STAT3 and apoptotic pathways.

Abstract
Siganus fuscescens, which is a small commercially important marine fish, is wildly distributed in shallow waters throughout the tropical and subtropical Indo-Pacific and Eastern Mediterranean regions. It is part of a group known as rabbitfish. Fifteen new polymorphic microsatellite markers for S. fuscescens were identified, and 32 wild individuals were used to evaluate the degree of polymorphism of these markers. The number of alleles per locus ranged from 2 to 12, and the polymorphism information content ranged from 0.210 to 0.849. The observed and expected heterozygosities were 0.142-0.808 and 0.225-0.853, respectively. Although significant deviations from Hardy-Weinberg equilibrium were detected at 2 loci (Sf1-37-2 and Sf1-47), no significant deviations were detected at the other 13 loci. These microsatellite markers will provide a useful tool for studies on genetic diversity and differentiation of S. fuscescens.

Abstract
The green lipped mussel, also known as the Asian green mussel (Perna viridis) is a fast reproducing and valuable food source, but it is also considered an invasive species and can clog and damage pipes and marine equipment. Eight novel polymorphic microsatellite loci for P. viridis were isolated and characterized. Microsatellite polymorphism was evaluated in 30 individuals collected from Xiamen, China. The number of alleles per locus and the polymorphism information content ranged from 2 to 5 and from 0.3092 to 0.7031, respectively. The observed and expected heterozygosities were 0.1538-0.8400 and 0.1448-0.6833, respectively. The loci identified in this study could provide a useful tool for the genetic population structure analysis of P. viridis.

Abstract
The onset of resistance to approved anti-AIDS drugs by HIV necessitates the search for novel inhibitors of HIV-1 reverse transcriptase (RT). Developing single molecular agents concurrently occupying the nucleoside and nonnucleoside binding sites in RT is an intriguing idea but the proof of concept has so far been elusive. As a first step, we describe molecular modeling to guide focused chemical syntheses of conjugates having nucleoside (d4T) and nonnucleoside (TIBO) moieties tethered by a flexible polyethylene glycol (PEG) linker. A triphosphate of d4T-6PEG-TIBO conjugate was successfully synthesized that is recognized as a substrate by HIV-1 RT and incorporated into a double-stranded DNA.

Abstract
OBJECTIVES A remarkable increase in traumatic spinal cord injury (TSCI) morbidity has occurred in China from 2001 to 2010 due to rapid industrial and economic development; this increase seriously threatens public health. The current study investigated the major causes and severity of TSCI in 561 hospitalized TSCI patients who came from all over China to the General Hospital of Chinese People's Armed Police Forces. METHODS Information (including each patient's age, gender, time and cause of injury and severity of spinal cord injury (SCI, complete or incomplete)) regarding 561 hospitalized TSCI patients whose injuries occurred between 2001 and 2010 was retrospectively analyzed. RESULTS Among the 561 patients, the youngest was 9 months old and the oldest was 67 years old; the average patient age was 34.74 ± 12.24 years. The sex ratio was 4.1:1 (male:female). The injuries were primarily caused by transportation accidents (51.2%), falling from a height (23.9%), tamping (8.6%), stumbling (8.0%), stabbing (3.0%) and crushing (1.8%). Although no statistically significant associations were observed between the different injury causes and severity of the injury, a statistically significant association was observed between the different injury causes and levels of the lesion. CONCLUSION Transportation accidents, falling from a height, tamping, stumbling, stabbing and crushing are the most common causes of TSCI. No statistically significant relationships were observed between certain injury causes and either complete or incomplete injury. However, different injury causes usually led to different levels of the lesion. No statistical differences were observed between the levels of the lesion and either complete or incomplete injury.

Abstract
Mechanisms that underlie early ischemic damages to the blood-brain-barrier (BBB) are not well understood. This study presents a novel magnetic resonance imaging (MRI) technique using a widely available pulse sequence and a long-circulating intravascular contrast agent to quantify water movements across the BBB at early stages of stroke progression. We characterized the integrity of the BBB by measuring the flip angle dependence of the water exchange-affected MRI signal intensity, to generate an efficient quantitative index of vascular permeability (WEI, or water exchange index). We performed in vivo MRI experiments to measure the transvascular WEI immediately after the permanent filament occlusion of the middle cerebral artery of mice (n = 5), in which we monitored changes in blood volume (V(b)), apparent diffusion coefficient (ADC), and intra-/extravascular WEI for 4 hours. Statistically significant elevations (P < 0.05) of WEI in the ischemic tissue were observed as early as 1 hour after ischemic onset. Initial reduction of the apparent blood volume (V(app)) in the infarct cortex was followed by a continuous increase of V(app) over time. Although the measured ADC in the ipsilesional cortex continuously decreased, the abnormally high intra-/extravascular WEI remained constant at a significantly elevated level, indicating apparent BBB injury at this early stage of stroke.
