Abstract
γδT cells function as sentinels in early host responses to infections and malignancies. Previously, we found ectopically expressed human MutS homologue 2 (hMSH2), recognized by γδT cells, triggered a γδT cell-mediated cytolysis to tumor cells. However, the characteristics of hMSH2-specific γδ Τ cells are not fully understood. In this study, we investigated the complementary determinant region (CDR) 3δ diversity of hMSH2-specific γδ T cells. We found that the CDR3δ sequences of hMSH2-specific γδ T cells displayed limited diversity, while the length and germline gene usage showed no differences compared with whole CDR3δ immune repertoire. There are more hydrophilic amino acids in P/N insert of hMSH2-specific γδ T cells including the more conserved amino acid at the position 97. Our results offer clues to understanding antigen recognition pattern of γδ T cells to stress-induced hMSH2 of tumor cells and also the mechanism of γδT cell-mediated tumor immune surveillance.

Abstract
The objective of this study was to determine the expression of miR-483 and miR-483*
and the relationship among them, their host gene (Igf2), and other
cytokines in a murine model of renal fibrosis. The extent of renal fibrosis was
visualized using Masson staining, and fibrosis was scored 3 days and 1 and 2 weeks
after unilateral ureteral obstruction (UUO). Expression of miR-483, miR-483* and
various cytokine mRNAs was detected by real-time polymerase chain reaction (PCR).
Expression of miR-483 and miR-483* was significantly upregulated in the UUO model,
particularly miR-483 expression was the greatest 2 weeks after surgery. Additionally,
miR-483 and miR-483* expression negatively correlated with Bmp7
expression and positively correlated with Igf2,
Tgfβ, Hgf, and Ctgf expression,
as determined by Pearson's correlation analysis. Hgf expression
significantly increased at 1 and 2 weeks after the surgery compared to the control
group. This study showed that miR-483 and miR-483* expression was upregulated in a
murine UUO model. These data suggest that miR-483 and miR-483* play a role in renal
fibrosis and that miR-483* may interact with miR-483 in renal fibrosis. Thus, these
miRNAs may play a role in the pathogenesis of renal fibrosis and coexpression of
their host gene Igf2.

Abstract
We use multiple-tip Langmuir probes and fast imaging to unambiguously identify and study the dynamics of underlying instabilities during the controlled route to fully-developed plasma turbulence in a linear magnetized helicon plasma device. Langmuir probes measure radial profiles of electron temperature, plasma density and potential; from which we compute linear growth rates of instabilities, cross-phase between density and potential fluctuations, Reynold's stress, particle flux, vorticity, time-delay estimated velocity, etc. Fast imaging complements the 1D probe measurements by providing temporally and spatially resolved 2D details of plasma structures associated with the instabilities. We find that three radially separated plasma instabilities exist simultaneously. Density gradient driven resistive drift waves propagating in the electron diamagnetic drift direction separate the plasma into an edge region dominated by strong, velocity shear driven Kelvin-Helmholtz instabilities and a central core region which shows coherent Rayleigh-Taylor modes propagating in the ion diamagnetic drift direction. The simultaneous, complementary use of both probes and camera was crucial to identify the instabilities and understand the details of the very rich plasma dynamics.

Abstract
OBJECTIVE To compare the diagnostic capabilities between capsule endoscopy (CE) and multislice CT (MSCT) enterography in combination with MSCT angiography for assessment of obscure gastrointestinal bleeding (OGIB). METHODS A total of 127 patients with OGIB were looked at in this study. 82 patients (aged 42.7 ± 19.1 years; 34 males) were assigned to receive MSCT diagnosis and 67 patients to (aged 53.9 ± 16.2 years; 28 males) receive CE diagnosis. Among them, 22 patients (aged 54.1 ± 19.1 years; 12 males) received both examinations. Oral isotonic mannitol and intramuscular injection of anisodamine were performed; non-ionic contrast (iopromide, 370 mg I ml(-1)) was intravenously administered; and then multiphase scanning was conducted at arterial, small intestinal and portal venous phases in MSCT. The results were compared with findings of reference standards including double balloon enteroscopy, digital subtraction angiography, intraoperative pathological examination and/or clinical diagnosis. RESULTS Administration of anisodamine markedly increased the satisfaction rate of bowel filling (94.67% vs 28.57%; p < 0.001) but not the diagnostic yield (p = 0.293) of MSCT. Compared with MSCT, CE showed an improved overall diagnostic yield (68.66% vs 47.56%; p = 0.010), which was also observed in overt bleeding patients (i.e. patients with continued passage of visible blood) (76.19% vs 51.02%; p = 0.013) and in patients aged younger than 40 years of age (85% vs 51.28%; p = 0.024). However, CE had similar positive rates to MSCT (p > 0.05). Among the 22 cases in whom both examinations were conducted, CE showed no significantly different diagnostic capability compared with MSCT (p = 0.4597). CONCLUSION Both CE and MSCT are safe and effective diagnostic methods for OGIB. ADVANCES IN KNOWLEDGE CE is preferred for overt bleeding or patients aged younger than 40 years. The combined use of CE and MSCT is recommended in OGIB diagnosis.

Abstract
BACKGROUND The epidemiology, diagnosis, and treatment of motor neuron disease (MND) in Chinese patients are ill known. METHODS A registered study of 461 MND patients was conducted across 10 facilities in 7 Chinese cities from February 2009 to March 2010. RESULTS Patients were classified as amyotrophic lateral sclerosis (ALS) (84.4%), progressive bulbar palsy (PBP) (4.1%), progressive muscular atrophy (PMA) (10.4%), or primary lateral sclerosis (PLS) (0.9%). MND was predominant in men (men/women; 1.6:1.0). Mean onset age was 52.6 years, with the highest incidence being observed between 51 and 60 years. Notably, 26.0% of MND patients were employed in forestry, fishery, or animal husbandry industries. Ten cases (2.7%) reported family history of MND, and 54.2% exhibited cervical onset. MND was also associated with head/neck trauma. Non-invasive positive pressure ventilation was the most common supportive therapy. CONCLUSION As a novel comprehensive report of a Chinese population, this study reveals that epidemiological characteristics of MND patients were similar to those observed in international populations. MND is age-related, male gender predominant, and may be associated with both environmental and genetic risk factors.

Abstract
UNLABELLED We found that type 2 diabetes mellitus (T2DM) was associated with increased fracture risks in non-obese postmenopausal Chinese women, and suppressed bone turnover might be the underlying mechanism. This is the first study evaluating and explaining the association of T2DM with osteoporotic fracture in Chinese population with such high homogeneity. INTRODUCTION The aim of this study was to investigate the association of T2DM with osteoporotic fracture in postmenopausal Chinese women. METHODS One thousand four hundred ten postmenopausal women were included and stratified into non-obese population [body mass index (BMI) < 25 kg/m(2)] and obese population (BMI ≥ 25 kg/m(2)). Each type of population was classified into diabetes group, impaired fasting glucose (IFG) group, and normal glucose group. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry. Serum C-terminal telopeptide of type I collagen (β-CTX) and serum N-amino terminal prepeptide of type 1 procollagen (P1NP) were quantified. Vertebral fractures (VFs) and non-VFs were assessed by vertebral X-ray and questionnaire, respectively. RESULTS Comparing to normal glucose group, diabetes group and IFG group both had lower levels of P1NP and β-CTX, despite population types. Despite having non-decreased BMD, non-obese diabetic patients had higher risks of total fracture and VF than BMI-matched normal glucose subjects (both P < 0.05). Non-obese population was further classified by a mean value of P1NP or β-CTX. Non-obese diabetic patients with low P1NP or high β-CTX had higher fracture risks (both P < 0.05), comparing to non-obese normal glucose subjects with high P1NP or high β-CTX, respectively. CONCLUSIONS Type 2 diabetic patients had suppressed bone turnover, which might explain the increased fracture risks, independent of BMD. IFG patients might also have poor bone quality and need early prevention.

Abstract
We conducted an antibiotic susceptibility survey of 830 blood-borne methicillin resistant Staphylococcus aureus collected from nationwide hospitals in Japan over a three-year period from January 2008 through May 2011. Antibiotic susceptibility was judged according to the criteria recommended by the Clinical Laboratory Standard Institute. Over 99% of the MRSA showed to be susceptible to teicoplanin, linezolid, sulfamethoxazole/trimethoprim and vancomycin, and over 97% of them were susceptible to daptomycin, arbekacin and rifampin. The majority of the MRSA strains showed resistant to minocycline, meropenem, imipenem, clindamycin, ciprofloxacin, cefoxitin, and oxacillin in the rates of 56.6, 72.9, 73.7, 78.7, 89.0, 99.5, and 99.9%, respectively. Among the MRSA strains, 72 showed reduced susceptibility to vancomycin, including 8 strains (0.96%) of vancomycin-intermediate S. aureus (VISA), 54 (6.51%) of heterogeneous vancomycin-intermediate S. aureus (hVISA), and 55 (5.63%) of β-lactam antibiotics-induced vancomycin resistant S. aureus (BIVR). Unexpectedly, among the 54 hVISA and 55 BIVR, 45 isolates (83.3% and 81.8%, respectively) showed both hVISA and BIVR phenotypes. A new trend of vancomycin resistance found in this study was that VISA strains were still prevalent among the bacteremic specimens. The high rates of the hVISA/BIVR two-phenotypic vancomycin resistance, and the prevalence of VISA in the bloodborne MRSA call attention in the MRSA epidemiology in Japan.

Abstract
For degenerative retinal diseases, like the acquired form exemplified by age-related macular degeneration (AMD), there is currently no cure. This study was to explore a stem cell therapy and a stem cell based gene therapy for sodium iodate (SI)-induced retinal degeneration in rats. Three cell types, i.e., rat mesenchymal stem cells (rMSCs) alone, erythropoietin (EPO) gene modified rMSCs (EPO-rMSCs) or doxycycline (DOX) inducible EPO expression rMSCs (Tet-on EPO-rMSCs), were transplanted into the subretinal spaces of SI-treated rats. The rMSCs were prepared for transplantation after 3 to 5 passages or modified with EPO gene. During the 8 weeks after the transplantation, the rats treated with rMSCs alone or with two types of EPO-rMSCs were all monitored with fundus examination, fundus fluorescein angiography (FFA) and electroretinogram. The transplantation efficiency of donor cells was examined for their survival, integration and differentiation. Following the transplantation, labeled donor cells were observed in subretinal space and adopted RPE morphology. EPO concentration in vitreous and retina of SI-treated rats which were transplanted with EPO-rMSCs or Tet-on EPO-rMSCs was markedly increased, in parallel with the improvement of retinal morphology and function. These findings suggest that rMSCs transplantation could be a new therapy for degenerative retinal diseases since it can protect and rescue RPE and retinal neurons, while EPO gene modification to rMSCs could be an even better option.

Abstract
We report here a novel strategy to redirect oncolytic adenoviruses to CD123 by carry a soluble coxsackie-adenovirus receptor (sCAR)-IL3 expression cassette in the viral genome to form Ad.IL3, which sustainably infected acute myeloid leukemia (AML) cells through CD123. Ad.IL3 was further engineered to harbor gene encoding manganese superoxide dismutase (MnSOD) or mannose-binding plant lectin Pinellia pedatisecta agglutinin (PPA), forming Ad.IL3-MnSOD and Ad.IL3-PPA. As compared with Ad.IL3 or Ad.sp-E1A control, Ad.IL3-MnSOD and Ad.IL3-PPA significantly suppressed in vitro proliferation of HL60 and KG-1 cells. Elevated apoptosis was detected in HL60 and KG-1 cells treated with either Ad.IL3-MnSOD or Ad.IL3-PPA. The caspase-9–caspase-7 pathway was determined to be activated by Ad.IL3-MnSOD as well as by Ad.IL3-PPA in HL60 cells. In an HL60/Luc xenograft nonobese diabetic/severe-combined immunodeficiency mice model, Ad.IL3-MnSOD and Ad.IL3-PPA suppressed cancer cell growth as compared with Ad.IL3. A significant difference of cancer cell burden was detected between Ad.IL3 and Ad.IL3-PPA groups at day 9 after treatment. Furthermore, Ad.IL3-MnSOD significantly prolonged mouse survival as compared with Ad.sp-E1A. These findings demonstrated that Ad.IL3-gene could serve as a novel agent for AML therapy. Harboring sCAR-ligand expression cassette in the viral genome may provide a universal method to redirect oncolytic adenoviruses to various membrane receptors on cancer cells resisting serotype 5 adenovirus infection.

Abstract
Background: The role of tumour-infiltrating inflammation in the prognosis of patients with colorectal cancer (CRC) has not been fully evaluated. The primary objective of our meta-analysis was to determine the impact of tumour-infiltrating inflammation on survival outcomes. Methods: Ovid MEDLINE and EMBASE were searched to identify studies reporting the prognostic significance of tumour-infiltrating inflammation for patients with CRC. The primary outcome measures were overall survival (OS), cancer-specific survival (CS) and disease-free survival (DFS). Results: A total of 30 studies involving 2988 patients were identified. Studies were subdivided into those considering the associations between CRC survival and generalised tumour inflammatory infiltrate (n=12) and T lymphocyte subsets (n=18). Pooled analyses revealed that high generalised tumour inflammatory infiltrate was associated with good OS (HR, 0.59; 95% CI, 0.48–0.72), CS (HR, 0.40; 95% CI, 0.27–0.61) and DFS (HR, 0.72; 95% CI, 0.57–0.91). Stratification by location and T lymphocyte subset indicated that in the tumour centre, CD3+, CD8+ and FoxP3+ infiltrates were not statistically significant prognostic markers for OS or CS. In the tumour stroma, high CD8+, but not CD3+ or FoxP3+ cell infiltrates indicated increased OS. Furthermore, high CD3+ cell infiltrate was detected at the invasive tumour margin in patients with good OS and DFS; and high CCR7+ infiltrate was also indicated increased OS. Conclusion: Overall, high generalised tumour inflammatory infiltrate could be a good prognostic marker for CRC. However, significant heterogeneity and an insufficient number of studies underscore the need for further prospective studies on subsets of T lymphocytes to increase the robustness of the analyses.

Abstract
BACKGROUND AND OBJECTIVES Mechanical stimulation and hormones act via interconnected signaling pathways to influence the function of bone cells. Estrogen receptor (ER) and β-catenin play important role in bone formation and have implicated in mechanotransduction in bone cells. To investigate the interaction between mechanotransduction and estrogenic signaling in mesenchymal stem cells (MSCs), this study examined the effect of mechanical strain and estrogen on activation of β-catenin in MSCs, and the role of ER in response to mechanical strain and estrogen in MSCs. MATERIALS AND METHODS MSCs were exposed to mechanical strain (2%, 1 Hz) and estrogen (100 nM). The ER inhibitor, ICI182,780 was used to assess the role of ER in activation of β-catenin stimulated by mechanical strain and estrogen. Changes of activated β-catenin in the nuclei were determined by immunoflourescent test. The expression of β-catenin was detected by western blotting. RESULTS Mechanical strain and estrogen augment, respectively, activation of β-catenin and accumulation of activated β-catenin in the nuclei of MSCs. Combined treatment with estrogen and mechanical strain had higher levels of activated β-catenin than the cells exposed to mechanical strain or estrogen. After MSCs were pre-treated by ICI182,780, the level of activated β-catenin expression induced by mechanical strain or estrogen was depressed. Meanwhile, ICI182,780 blocked effect of combined stimulation on activation of β-catenin in MSCs. CONCLUSIONS Our study demonstrates that mechanical strain and estrogen both promote the levels of activated β-catenin in MSCs. Estrogen receptor implicates in activation of β-catenin stimulation by mechanical strain and estrogen in MSCs.

Abstract
In a previous study, we elucidated the specific microRNA (miRNA) profile of hepatic differentiation. In this study, we aimed to clarify the instructive role of six overexpressed miRNAs (miR-1246, miR-1290, miR-148a, miR-30a, miR-424 and miR-542-5p) during hepatic differentiation of human umbilical cord lining-derived mesenchymal stem cells (hMSCs) and to test whether overexpression of any of these miRNAs is sufficient to induce differentiation of the hMSCs into hepatocyte-like cells. Before hepatic differentiation, hMSCs were infected with a lentivirus containing a miRNA inhibitor sequence. We found that downregulation of any one of the six hepatic differentiation-specific miRNAs can inhibit HGF-induced hepatic differentiation including albumin expression and LDL uptake. Although overexpression of any one of the six miRNAs alone or liver-enriched miR-122 cannot initiate hepatic differentiation, ectopic overexpression of seven miRNAs (miR-1246, miR-1290, miR-148a, miR-30a, miR-424, miR-542-5p and miR-122) together can stimulate hMSC conversion into functionally mature induced hepatocytes (iHep). Additionally, after transplantation of the iHep cells into mice with CCL4-induced liver injury, we found that iHep not only can improve liver function but it also can restore injured livers. The findings from this study indicate that miRNAs have the capability of directly converting hMSCs to a hepatocyte phenotype in vitro.

Abstract
T lymphocytes have been demonstrated to play a role in the development of diabetic proteinuria. However, the alteration of circulating T lymphocytes has not been investigated in a type 2 diabetic cohort. A cross-sectional study was conducted in Peking University Aerospace Center Hospital. 510 participants were type 2 diabetes mellitus, 30-70 years of age. Patients with immune disease, medical conditions that affect immune function, infection, or end-organ damage were excluded. The percentage of circulating CD8+ T lymphocytes was significantly associated with albuminuria in the cohort. The impact of albuminuria to CD8+ T lymphocytes in a multivariate linear regression model was indicated by the B- coefficient (95% confidence interval) 1.812 (0.204-3.421, P=0.03). Our data first showed that the percentage of circulating CD8+ T cells is associated with albuminuria in type 2 diabetes mellitus, which may support the rationality of systemic inhibition of T lymphocytes in treating albuminuria in these patients.

Abstract
OBJECTIVES Treatment with Sclerostin antibody (Scl-Ab) has shown to enhance fracture healing in rodent and non-human primate models. The current study investigated the time-dependent changes during Scl-Ab treatment in a mouse osteotomy model. METHODS 1 day after osteotomy, C57BL mice received subcutaneous injection with vehicle or Scl-Ab at 25 mg/kg, twice/week for 2, 4, or 6 weeks. 20 mice from each group were necropsied at weeks 2, 4, and 6 for Micro-CT, histomorphmetry and mechanical testing examinations. RESULTS The bone mineral apposition rate at fracture callus was significantly higher in the Scl-Ab treated groups at all the time points. Micro-CT analysis showed that the volumetric bone mineral density (vBMD) and bone volume over tissue volume (BV/TV) in the Scl-Ab treated groups at 4 and 6 weeks were significantly greater than that of vehicle control groups. Mechanical testing showed that the maximum load of failure at the fracture callus increased significantly by 68% at 6 weeks in the Scl-Ab treated groups. CONCLUSIONS This study confirmed that mice treated with Scl-Ab increased bone formation from 2 weeks, bone mineral density and bone volume at 4 weeks, followed by significant increase in bone strength at the fracture site at 6 weeks. These results suggest that applying sclerostin antibody at early stage fracture healing promotes fracture healing.

Abstract
PURPOSE The presence of cerebral microbleeds (CMBs) may have predictive and diagnostic value for cerebrovascular diseases. The purpose of our study was to measure the phase values (PVs) of CMBs by phase maps. METHODS We retrospectively analyzed 75 patients with hypertension who had CMBs using enhanced T2*-weighted angiography (ESWAN). The PVs of CMBs were measured and documented. The mean PVs of CMBs were correlated with demographic features and the grade of white matter lesions for seven brain regions. RESULTS A total of 275 CMBs were found. Their mean PV was - 1.39 ± 0.29 radians. The mean PV of CMBs in seven brain regions was significantly lower than that of red nucleus and substantia nigra of healthy controls (P < .05). The mean PV of CMBs in the basal ganglia gray matter was significantly lower than that of the brainstem, subcortical white matter, and cerebellum (P < 0.05). In subcortical white matter, the PVs were significantly lower in patients with hypertension < 10 years than for those patients with hypertension ≥ 10 years (P < 0.05). In basal ganglia gray matter, the PVs were significantly lower in men than in women (P < 0.05). There was no significant correlation between the PVs of CMBs and the demographic features addressed or the grade of white matter lesions. CONCLUSIONS Measurement of the PV of phase maps using ESWAN sequence provides quantitative information for detection of CMBs. The measurement data reported herein will provide a reference for a longitudinal study of CMBs in the future.

Abstract
L-arginine (L-Arg), the precursor of nitric oxide (NO), plays multiple important roles in nutrient metabolism and immune regulation. L-Arg supplement serves as a potential adjunctive therapy for severe malaria, because it improves NO bioavailability and reverses endothelial dysfunction in severe malaria patients. In this study, we investigated the effect of dietary L-Arg supplement on host immune responses during subsequent malaria infection using the Plasmodium yoelii 17XL - BALB/c mouse model. We have shown that pretreatment of mice with L-Arg significantly decreased parasitemia and prolonged the survival time of mice after infection. L-Arg supplement led to significant increases in activated CD4(+)T-bet(+)IFN-γ(+) T cells and F4/80(+)CD36(+) macrophages during early-stage infection, which were accompanied by enhanced synthesis of IFN-γ, TNF-α and NO by spleen cells. Moreover, L-Arg-pretreated mice developed more splenic myeloid and plasmacytoid dendritic cells with up-regulated expression of MHC II, CD86 and TLR9. In comparison, L-Arg treatment did not change the number of regulatory T cells and the level of anti-inflammatory cytokine IL-10. Taken together, our results showed that L-Arg pretreatment could improve the protective immune response in experimental malaria infection in mice, which underlines potential importance of L-Arg supplement in malaria-endemic human populations.

Abstract
γδ T cells are characterized by recognizing conserved endogenous and stress-induced antigens without antigen presentation. It has been show that γδ T cells play an important role in anti-tumour/microbe responses, but their function in autoimmune diseases is yet not clear. Here, we reported the quantity and phenotype of peripheral blood γδ T cells from systemic lupus erythematosus (SLE). Both the percentages of γδ T cells in peripheral blood and among CD3(+) T cells of patients with SLE were significantly decreased, regardless of disease activity. However, activating marker CD69 and HLA-DR was upregulated, while inhibiting receptor CD94/NKG2A was downregulated in γδ T cells of patients with SLE. The expression of CD69 is negatively correlated with the quantity of γδ T cells. Moreover, the expression of CD94/NKG2A remained low even with antigen stimulation on those γδ T cells. Our results suggested that the low expression level of CD94/NKG2A upon γδ T cell activation might lead to the over-activation of γδ T cells in patients with SLE. These findings will be useful in elucidating the roles of γδ T cells in SLE pathogenesis.

Abstract
OBJECTIVE To examine the pattern and extent to which other physical conditions are comorbid with migraine and other headaches in youth in a representative sample of the US population. STUDY DESIGN The National Comorbidity Survey-Adolescent Supplement is a face-to-face survey of adolescents aged 13-18 years in the continental US. Sufficient information to assess the International Headache Society's criteria for migraine with and without aura over the past 12 months was available in the diagnostic module. A caretaker/parental self-administered report was used to assess a broad range of other physical conditions. The sample for these analyses was 6843 adolescents with systematic caretaker/parent reports. RESULTS Adolescents with any headaches reported higher rates of other neurologic conditions, including epilepsy (OR, 2.02; 95% CI, 1.04-3.94), persistent nightmares (OR, 2.28; 95% CI, 1.34-3.87), and motion sickness (OR, 1.6; 95% CI, 1.07-2.4), as well as abdominal complaints (OR, 2.36; 95% CI, 1.59-3.51). Asthma (OR, 2.22; 95% CI, 1.26-3.92) and seasonal allergies (OR, 1.66; 95% CI, 1.12-2.48) were more common in adolescents with migraines than in adolescents with nonspecific headaches. CONCLUSION Adolescent migraine is associated with inflammatory conditions such as asthma and seasonal allergies, as well as with epilepsy, persistent nightmares, and motion sickness. Our findings suggest that comorbid medical conditions should be evaluated comprehensively in determining treatment options in youth with headache. Such comorbidity also could be an important source of the clinical and etiologic heterogeneity in migraine.

Abstract
In the present study, Torque teno sus virus (TTSuV) was detected from different tissues, stool and serum samples of 25 sick pigs. The total prevalence of TTSuV1 and TTSuV2 were 64% (16/25) and 28% (7/25), 24% (6/25) were co-infected with both TTSuV1 and TTSuV2. The prevalence of TTSuV infection in spleen is a slightly higher, with positive rates of 52% (13/25) for TTSuV1 and 24% (6/25) for TTSuV2. Phylogenetic analysis of TTSuV1 showed that 21 isolates were distributed into two clusters (genotype TTSuV1a and TTSuV1b), with genotype TTSuV1b was the dominant genotype. Phylogenetic analysis of TTSuV2 showed that the nine isolates shared 80.9-99.2% nucleotide homology with each other, and were distributed in different genotypes (TTSuV2a-TTSuV2f). TTSuV2d was the most prevalent genotype in this study, which contained five Spanish strains and nine Chinese strains, and shared 94.2-96.8% homology.

Abstract
Avian astrovirus infections are widespread in many countries, and infections have been linked to enteritis and increased mortality in young poultry. Although pigeons are treated as an important poultry product in some countries, their diseases are often poorly understood and astrovirus infection in pigeons has not been reported. In the present study, faecal samples were collected during an outbreak of gastrointestinal illness in a population of Shanghai pigeons. The samples were examined for astroviruses by reverse transcription-polymerase chain reaction. Eighty-nine per cent (40/45) and 4% (2/45) were found to be positive for avian nephritis virus (ANV) and chicken astrovirus, respectively. One positive sample indicated a co-infection with both ANV and chicken astrovirus. Phylogenetic analysis based on the partial polymerase gene sequence and full-length capsid protein from published avian astrovirus sequences in GenBank revealed that the pigeon viruses detected in this study were evolutionarily closely related to chicken ANV. The present study provided evidence for the presence of astrovirus in pigeons and suggests that cross-infection between pigeons and commercial chickens was likely. Whether the astroviruses in pigeons were responsible for the diarrhoea remains to be determined.

Abstract
Vγ4Vδ1 T cell receptor (TCRγ4δ1)-expressing γδT cells were the most dominant subset in gastric tumour-infiltrating γδT cells (γδTIL) we recently analyzed. To study the essential roles of γ and δ chains in assembly and function of TCRγ4δ1, we sequenced and constructed them into lentiviral vectors for the reconstitution of TCRγ4δ1 using different modalities of transduction. We were able to efficiently reconstitute TCRγ4δ1 with functional activities when both γ4 and δ1 chains are coexpressed in TCR-negative J.RT3-T3.5 cells. However, the expression of δ1 chain is greatly diminished when γ4 expression is absent, suggesting that the coexpressing γ4 is critical in maintaining the folding and stability of δ1 product. To functionally study the reconstituted TCRγ4δ1, we examined the cytolytic activity of TCRγ4δ1-reconstituted J.RT3-T3.5 cells and cytokine secretion and found the receptors are fully functional, but their functionality also requires the presence of γ4. Our results demonstrated that γ4 is critical for the stability of δ1 and the function of TCRγ4δ1.

Abstract
Osteonecrosis of the femoral head was induced in rabbits by intramuscular injection of methylprednisolone and vascular occlusion of the capital femoral epiphysis by electrocoagulation. Eight weeks later the animals received no treatment (group A), core decompression by drilling a hole (diameter 1.2 mm) from the outer cortex 2.5 cm distal to the proximal end of the greater trochanter (group B), or injection of 107 autologous adipose-derived stem cells (ADSCs) directly into the femoral head (group C). Eight weeks later, microcomputed tomography scans indicated that bone and trabecular volume and density were significantly higher in group C than in other groups. Histology indicated more new bone formation in group C than in other groups. Group C showed strong osteocalcin immunoreactivity in subchondral bone osteoblasts in the necrotic femoral head, whereas few osteocalcin-positive cells were found among osteoblasts in other groups. Thus, autologous ADSC transplantation improved osteogenesis and the microstructure of vascular deprivation-induced osteonecrotic tissue.

Abstract
The Asiatic topmouth gudgeon, Pseudorasbora parva, is recognized as one of the most invasive fish species in many countries outside of Asia. We isolated and characterized 19 microsatellite loci from P. parva. The polymorphism of these 19 loci was tested on 40 individuals of P. parva sampled from a wild population located in Ezhou, Hubei province of China. The loci had 5 to 11 alleles, with a mean of 7.7 at each locus; 11 loci conformed to Hardy-Weinberg equilibrium. The expected and observed heterozygosities ranged from 0.237 to 0.973 and from 0.647 to 0.914, respectively. All microsatellite loci were in linkage equilibrium. These microsatellite markers are potentially useful for the assessment of population genetic structure during invasion and dispersal of P. parva in new habitats.

Abstract
INTRODUCTION The 2009 (H1N1) influenza A pandemic started in April 2009 and has since spread globally. We have noticed that critically ill patients with confirmed pandemic 2009 (H1N1) influenza A require mechanical ventilation. This paper describes the use of intravenous zanamivir in this group of patients. METHODS Patients who had severe pneumonia with 2009 (H1N1) influenza A and required intravenous zanamivir were referred to the Infectious Diseases Department of our institution. Clinical data was collected from these patients. Clinical samples were sent to the National Public Health Laboratory for sequencing. RESULTS A total of five patients used intravenous zanamivir from April 8 to May 8, 2010. Only one death was reported. There were no side effects attributable to the use of intravenous zanamivir. H275 mutation, which confers resistance to oseltamivir, was seen in a subpopulation of the virus in one case. CONCLUSION Physicians can consider using intravenous zanamivir for the treatment of critically ill patients with 2009 (H1N1) influenza A infection.

Abstract
A novel influenza A(H1N1)2009 variant with mildly reduced oseltamivir and zanamivir sensitivity has been detected in more than 10% of community specimens in Singapore and more than 30% of samples from northern Australia during the early months of 2011. The variant, which has also been detected in other regions of the Asia-Pacific, contains a S247N neuraminidase mutation. When combined with the H275Y mutation, as detected in an oseltamivir-treated patient, the dual S247N+H275Y mutant had extremely high oseltamivir resistance.
