Abstract
There is still no effective clinical antiviral drug against human enterovirus 71 (EV71) infection, which causes hand, foot and mouth disease (HFMD) in children. Scavenger receptor class B member 2 (SCARB2) is an important receptor of EV71 as it plays a vital role in the early steps of viral infection. In this study, recombinant SCARB2 protein was expressed and purified in a prokaryotic expression system, and was identified by western blot with a monoclonal antibody and mass spectrometry analysis. Detection of the sera from mice immunized with the recombinant SCARB2 protein using ELISA and western blot showed good immunogenicity of the recombinant protein. Furthermore, in the neutralization test cytopathic effect was significantly decreased when EV71 was incubated with the immune sera before infection. In summary, the SCARB2 protein was expressed successfully, and the immune sera showed obvious antiviral effect against EV71. This study provides useful information about the interaction mechanism between SCARB2 and EV71, and is also helpful for further clinical treatment research of HFMD.

Abstract
OBJECTIVE The purpose of this study is to evaluate the histocompatibility and feasibility of structure and function of bone marrow mesenchymal stem cells (BMSCs) and silk fibroin meniscus porous scaffolds in repairing meniscus injury in rabbits. MATERIALS AND METHODS BMSCs were cultured and identified in vitro, silk fibroin meniscus porous scaffolds were prepared and the histocompatibility of porous scaffolds was evaluated via in vitro culture. Silk fibroin-BMSCs porous scaffolds were implanted into the meniscus defect area of New Zealand white rabbits as the experimental group, the blank scaffold group without BMSCs, pure BMSCs group and blank control group were set up with 10 rabbits in each group. Joint capsules were opened for general observation at 6 weeks and 12 weeks after operation. The specimens received the HE staining, alkaline toluidine blue staining, and immunohistochemical staining of Type I and Type II collagen and S100 protein. RESULTS In vitro HE staining and SEM observation showed that the scaffolds showed the sponge-like structure with abundant microporous structure on the surface and inside, which had a good histocompatibility with BMSCs. At 6 and 12 weeks after operation in experimental group, meniscus-like tissues were found in the meniscus defect area. HE staining showed the fibrous cartilage-like structure and obvious collagenous fiber structure around arranged in an orderly manner. Alkaline toluidine blue staining showed the cartilage-specific glycosaminoglycan (GAG); Type I and Type II collagen and S100 protein staining were strongly positive. However, the above changes were not seen in other groups. CONCLUSIONS BMSCs and silk fibroin meniscus porous scaffolds have a better histocompatibility and feasibility of structure and function in repairing meniscus injury in rabbits.

Abstract
Objectives The aim of this study was to identify key pathological genes in osteoarthritis (OA). Methods We searched and downloaded mRNA expression data from the Gene Expression Omnibus database to identify differentially expressed genes (DEGs) of joint synovial tissues from OA and normal individuals. Gene Ontology (GO) and Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathway analyses were used to assess the function of identified DEGs. The protein-protein interaction (PPI) network and transcriptional factors (TFs) regulatory network were used to further explore the function of identified DEGs. The quantitative real-time polymerase chain reaction (qRT-PCR) was applied to validate the result of bioinformatics analysis. Electronic validation was performed to verify the expression of selected DEGs. The diagnosis value of identified DEGs was accessed by receiver operating characteristic (ROC) analysis. Results A total of 1085 DEGs were identified. KEGG pathway analysis displayed that Wnt was a significantly enriched signalling pathway. Some hub genes with high interactions such as USP46, CPVL, FKBP5, FOSL2, GADD45B, PTGS1, and ZNF423 were identified in the PPI and TFs network. The results of qRT-PCR showed that GADD45B, ADAMTS1, and TFAM were down-regulated in joint synovial tissues of OA, which was consistent with the bioinformatics analysis. The expression levels of USP46, CPVL, FOSL2, and PTGS1 in electronic validation were compatible with the bio-informatics result. CPVL and TFAM had a potential diagnostic value for OA based on the ROC analysis. Conclusion The deregulated genes including USP46, CPVL, FKBP5, FOSL2, GADD45B, PTGS1, ZNF423, ADAMTS1, and TFAM might be involved in the pathology of OA. Cite this article: X. Zhang, Y. Bu, B.

Abstract
OBJECTIVE To investigate the risk factors for the short-term outcome of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF), and to establish a risk model for predicting the short-term outcome of these patients. METHODS A total of 338 patients with HBV-related ACLF who were admitted to 30 Lod hospital of PLA hospital from January 2010 to January 2014 were enrolled, and a prospective clinical follow-up was performed for them. Multivariate logistic regression was used to determine the risk factors for short-term (12 weeks) outcome, the predictive model with logistic regression equation was established, and the predictive value of this model was evaluated. RESULTS The multivariate logistic regression analysis showed that age, a family history of hepatitis B, hepatic encephalopathy (HE), hepatorenal syndrome (HRS), white blood cell (WBC), platelet (PLT), international normalized ratio (INR), total bilirubin (TBil), total bile acid (TBA), creatinine, Na, HBV DNA, and HBeAg were the independent risk factors for the short-term outcome of these patients. Logistic(p) = -4.466 + 1.192 age + 1.631 family history of hepatitis B + 1.091 HE + 1.631 HRS + 1.208 WBC -1.487 PLT + 1.092 INR + 1.446 TBil + 1.608 TBA -1.101 CHE + 1.279 CRE -1.713 Na + 1.032 HBV DNA + 0.833 HBeAg. The area under the receiver operating characteristic curve of the model for the prediction of short-term outcome was 0.930, the cut-off value was 3.16, the sensitivity was 0.860, and the specificity was 0.871. With the increasing scores of the equation, the mortality of patients tended to increase gradually. CONCLUSION Age, a family history of hepatitis B, HE, HRS, WBC, PLT, INR, TBil, TBA, CHE, CRE, Na, HBV DNA, and HBeAg are the independent risk factors for the short-term outcome of patients with HBV-related ACLF. The model for predicting short-term outcome established on the basis of independent risk factors has a better clinical value in guiding clinical therapy.

Abstract
BACKGROUND Psoriasis symptoms may decrease quality of life for patients. Skin-related personal relationship difficulties in psoriasis patients are common, under-reported and poorly understood. OBJECTIVE To assess the effect of ixekizumab (IXE) treatment on skin-related personal relationship difficulties in patients with moderate-to-severe psoriasis. METHODS Pooled data (N = 2570) on skin-related relationship problems were obtained from two large phase 3 trials (UNCOVER-2 and UNCOVER-3) in patients with moderate-to-severe plaque psoriasis randomized to subcutaneous placebo (PBO, N = 361), etanercept (ETN; 50 mg twice weekly, N = 740), or 80 mg IXE as one injection every 4 (IXEQ4W, N = 733) or 2 weeks (IXEQ2W, N = 736) for 12 weeks, following a 160-mg initial dose. The Dermatology Life Quality Index (DLQI) Personal Relationships Domain (PRD) (Items 8 and 9) was used to assess how much the skin caused any personal relationship difficulties at weeks 0, 2, 4 and 12. Improvement was compared for IXE vs PBO and ETN using logistic models. Factors associated with improvement were assessed using multiple linear regressions. DLQI Item 9, assessing sexual difficulties, was also analysed separately. RESULTS PRD scores (mean ± standard deviation) at baseline were similar across all treatment groups (PBO: 1.8 ± 1.9; ETN: 1.7 ± 1.8; IXEQ4W: 1.6 ± 1.8; IXEQ2W: 1.7 ± 1.8). Treatment with IXE rapidly and significantly improved the mean PRD score compared to PBO and ETN (P < 0.001 at all time points). Baseline PRD score was the strongest negative predictor of improvement. IXE enabled significantly more patients with moderate-to-severe plaque psoriasis to reduce their skin-related sexual difficulties at Week 12 compared to PBO (P < 0.001) or ETN (P < 0.001). CONCLUSION Ixekizumab improves patient-reported skin-related PRD difficulties in patients with moderate-to-severe psoriasis.

Abstract
Cervical cancer is a serious public health problem and is associated with high cancer-related mortality in females worldwide. The expression of IL17A can increase the migration and invasiveness of cervical cancer cells by activating the NF-κB signal pathway. Single-nucleotide polymorphisms (SNPs) can alter gene function and protein expression. We examined the association between two IL17A SNPs (rs2275913 and rs3748067) and the risk of cervical cancer. We also investigated the interaction between IL17A -174G/C and -572C/G mutations and environmental factors. Our 1:2 matched case-control study included 185 cervical cancer patients and 370 healthy controls. The IL17A rs2275913 and rs3748067 SNPs were genotyped by polymerase chain reaction-restriction fragment length polymorphism. Using logistic regression analysis, we found that individuals harboring the TT genotype of IL17A rs3748067 had an increased risk of cervical cancer compared with those carrying the CC genotype, and the adjusted OR (95%CI) was 6.29 (2.30-19.81). Moreover, individuals carrying the T allele of IL17A rs3748067 were more susceptible to cervical cancer than those with the C allele, and the adjusted OR (95%CI) was 2.31 (1.53-3.50). No significant interaction was observed between the IL17A rs2275913 polymorphism and cervical cancer risk. In conclusion, our study suggests that the IL17A rs3748067 polymorphism is independently associated with the risk of cervical cancer, and has a relationship with human papillomavirus infection with regard to the risk of cervical cancer.

Abstract
To screen effective antigens as therapeutic subunit vaccines against Mycobacterium latent infection, we did bioinformatics analysis and literature review to identify effective antigens and evaluated the immunogenicity of five antigens highly expressed in dormant bacteria, which included Rv2031c (HspX), Rv2626c (Hrp1), Rv2007c (FdxA), Rv1738 and Rv3130c. Then, several fusion proteins such as Rv2007c-Rv2626c (F6), Rv2031c-Rv1738-Rv1733c (H83), ESAT6-Rv1738-Rv2626c (LT40), ESAT6-Ag85B-MPT64<190-198> -Mtb8.4 (EAMM), and EAMM-Rv2626c (LT70) were constructed and their therapeutic effects were evaluated in pulmonary Mycobacterium bovis Bacilli Calmette-Guérin (BCG) - latently infected rabbit or mouse models. The results showed that EAMM and F6 plus H83 had therapeutic effect against BCG latent infection in the rabbit model, respectively, and that the combination of EAMM with F6 plus H83 significantly reduced the bacterial load. In addition, the fusion proteins LT40 and LT70 consisting of multistage antigens showed promising therapeutic effects in the mouse model. We conclude that subunit vaccines consisting of both latency and replicating-associated antigens show promising therapeutic effects in BCG latent infection animal models.

Abstract
Acute lung injury (ALI) is a major outcome of exposure to high levels of hydrogen sulfide (H2S). Dexamethasone (DXM) has been used to treat ALI. However, the mechanisms involved in H2S-induced ALI and the protective mechanisms of DXM in treating ALI are still nebulous. To explore the mechanisms involved, we evaluated the role of claudin-5 in the protective effect of DXM against H2S-induced ALI. Sprague-Dawley rats were exposed to H2S to establish the ALI model. In parallel with the animal model, a cell model was also established by incubating human umbilical vein endothelial cells (HUVECs) with NaHS. Lung hematoxylin-eosin staining, electron microscope assay, and wet/dry ratio were used to identify whether the ALI was successfully induced by H2S, and changes in claudin-5 expression were detected in both rats and HUVECs. Our results revealed that claudin-5 was markedly decreased after H2S exposure and that DXM significantly attenuated the H2S-induced downregulation of claudin-5 in both rats and HUVECs. In the animal experiment, p-Akt and p-FoxO1 presented a similar tendency as claudin-5, but their levels decreased 6 h prior to the levels of claudin-5. In a further investigation, the DXM-induced protective effect on ALI and rescue effect on downregulation of claudin-5 were both blocked by LY294002. The current study demonstrated that claudin-5 was involved in the development of H2S-induced ALI and that DXM exerted protective effects through increasing claudin-5 expression by activating the phosphatidylinositol 3-kinase pathway. Therefore, claudin-5 might represent a novel pharmacological target for treating ALI induced by H2S and other hazardous gases.

Abstract
BACKGROUND Patients with moderate-to-severe psoriasis report impaired health-related quality of life (HRQoL). OBJECTIVE To assess speed of onset of ixekizumab-induced clinically relevant improvement in HRQoL. METHODS This post hoc analysis used pooled data from patients randomized in UNCOVER-2 and UNCOVER-3, and treated with 80 mg ixekizumab every 2 weeks (IXEQ2W), 80 mg ixekizumab every 4 weeks (IXEQ4W), 50 mg etanercept (ETN) twice weekly or placebo (PBO) for 12 weeks. HRQoL and pruritus were assessed using the Dermatology Life Quality Index (DLQI) and Itch Numeric Rating Scale (NRS), respectively. Minimally clinical important differences (MCID) in DLQI and Itch NRS were defined as ≥5-point and ≥4-point improvements from baseline, respectively. Time to response from randomization was estimated using Kaplan-Meier methodology and the log-rank test. Hazard ratios between treatments were calculated using a Cox proportional hazards regression model adjusting for studies. RESULTS A total of 2570 patients were included: 361 PBO; 740 ETN; 733 IXEQ4W and 736 IXEQ2W. Significantly greater differences in time to DLQI ≥5 point or Itch NRS ≥4 point improvement for IXEQ2W or IXEQ4W compared with ETN and PBO (P < 0.001) were observed. The median time when 50% of patients reached a ≥5-point reduction in DLQI was shorter for ixekizumab-treated patients (2 weeks, both schedules) compared with ETN- (4 weeks) or PBO-treated (>12 weeks) patients. Likewise, the median time when 50% of patients reached a ≥4-point reduction in Itch NRS was shorter for ixekizumab-treated patients (2 weeks, both schedules) compared with ETN- (8 weeks) or PBO-treated (>12 weeks) patients. Significantly more ixekizumab-treated patients were likely to achieve MCIDs in DLQI or itch reduction compared with ETN or PBO after 12 weeks of treatment. CONCLUSION Ixekizumab-treated patients achieved more rapid improvements both in HRQoL and itch compared with patients treated with ETN and PBO.

Abstract
Objective: To explore the outcome of trial of labor after cesarean section(TOLAC). Methods: Totally 614 TOLAC were conducted in the First Affiliated Hospital of Kunming Medical University from July 2013 to June 2016. Among them, 586 cases of singleton pregnancy with one prior cesarean section(gestational age≥28 weeks)were studied retrospectively. The maternal and neonatal outcomes among the vaginal birth after cesarean(VBAC)group(481 cases), failed TOLAC group(105 cases)and the elective repeat cesarean section(ERCS)group(1 145 cases)were compared. Multiple logistic regression was used to determine the risk factors of admission to neonatal intensive care unit(NICU). Results: (1)The TOLAC rate was 29.62%(614/2 073)from July 2013 to June 2016, and the VBAC rate was 82.6%(507/614). The cesarean section rate was reduced by VBAC by 3.147%(507/16 112).(2)The comparison of adverse maternal outcomes: in the VBAC group, the postpartum hemorrhage volume was(431±299)ml, the rate of postpartum fever was 6.4%(31/481), the birth weight of the neonates was(3 085± 561)g, and the rate of large for gestational age was 2.9%(14/481). All were significantly lower than those in the failed TOLAC group and the ERCS group(P<0.05). There was no significant difference in other adverse maternal outcomes[the uterine rupture rate(0.2% ,1/481), the bladder injury rate(0), the proportion of postpartum hemorrhage volume≥1 500 ml(1.0%, 5/481), the blood transfusion rate(3.7%, 18/481)]and adverse perinatal outcomes[the rate of neonatal 5-minute Apgar score<7(0.4%, 21/481), the rate of umbilical arterial pH<7.0(0.6% , 3/481), the rate of the NICU admission and the perinatal mortality rate(12.3%, 59/481)]among the 3 groups(P>0.05). Multiple logistic regression showed no association between VBAC and admission to the NICU(OR=0.84, 95%CI: 0.58-1.21). The isolated risk factors for admission to the NICU were preterm birth(OR=16.71, 95% CI: 11.44-24.40), hypertensive disorder complicating pregnamcy(OR=3.89, 95% CI: 2.39-6.35), meconium stained amniotic fluid(OR=2.48, 95% CI: 1.62-3.80), small for gestational age(OR=2.00, 95% CI: 1.19-3.36)and diabetes mellitus(OR=1.69, 95% CI: 1.14-2.50). Conclusions: VBAC reduces cesarean section rate, with good outcomes in both mother and neonate. It is a safe and feasible way of labor in women with only one cesarean section history.

Abstract
INTRODUCTION Restoration of native head-shaft angle (HSA) is critical for treatment of proximal humerus fracture. However, HSA has not been properly investigated according to the humeral rotation. This study was designed to analyze the relationship between the humeral rotation and the HSA at 1° increments, and clarify its serial changing pattern according to the humeral rotation. HYPOTHESIS The angulation of HSA would be undervalued when the humerus is being rotated externally and it would be overvalued when it is being rotated internally. MATERIALS AND METHODS Eight dried cadaveric normal humeri were CT scanned. They were analyzed using computer-aided design with a standardized neutral position. HSA was the angle between the humeral shaft axis (SA) and the humeral head axis (HA). SA and HA were the best-fit lines through center of all the best-fitting circles in every cross section along the humeral shaft and within the humeral head, respectively. Each 3D model was rotated 30° internally and 45° externally relatives to the SA at 1° increments with the camera was fixed at antero-posterior view of neutral position. Angulation of HSA in every rotational degree was documented as ratio relatives to the angulation of HSA in neutral position. RESULTS The average HSA at neutral position was 133±1.93°. HSA was underestimated by 8±1.9% and it was overestimated by 20±5.1% at the maximum external rotation (ER) and internal rotation (IR), respectively. HSA was underestimated by 1% in every 5.8° of ER and overestimated by 1% in every 1.5° of IR. Rotational misalignments within 10° of IR and 18° of ER could be tolerated (P>.05). CONCLUSIONS HSA was underestimated at ER and was overestimated at IR. This information could be useful for surgeons in restoring the native HSA for treatment of proximal humerus fracture. TYPE OF STUDY Basic research study.

Abstract
Electrons can be efficiently injected into a plasma wave by colliding two counterpropagating laser pulses in a laser wakefield acceleration. However, the generation of a high-quality electron beam with a large charge is difficult in the traditional on-axis colliding scheme due to the growth of the electron beam duration coming from the increase of the beam charge. To solve this problem, we propose an off-axis colliding scheme, in which the collision point is away from the axis of the driver pulse. We show that the electrons injected from the off-axis region are highly concentered on the tail of the bubble even for a large trapped charge, thus feeling almost the same accelerating field. As a result, quasimonoenergetic electron beams with a large charge can be produced. The validity of this scheme is confirmed by both the particle-in-cell simulations and the Hamiltonian model. Furthermore, it is shown that a Laguerre-Gauss (LG) laser can be adopted as the injection pulse to realize the off-axis colliding injection in three dimensions symmetrically, which may be useful in simplifying the technical layout of the real experiment setup.

Abstract
Comprehensive measurements were conducted at the summit of Mount (Mt.) Huang, a rural site located in eastern China during the summer of 2011. They observed that ozone showed pronounced diurnal variations with high concentrations at night and low values during daytime. The Weather Research and Forecasting with Chemistry (WRF-Chem) model was applied to simulate the ozone concentrations at Mt. Huang in June 2011. With processes analysis and online ozone tagging method we coupled into the model system, the causes of this diurnal pattern and the contributions from different source regions were investigated. Our results showed that boundary layer diurnal cycle played an important role in driving the ozone diurnal variation. Further analysis showed that the negative contribution of vertical mixing was significant, resulting in the ozone decrease during the daytime. In contrast, ozone increased at night owing to the significant positive contribution of advection. This shifting of major factor between vertical mixing and advection formed this diurnal variation. Ozone source apportionment results indicated that approximately half was provided by inflow effect of ozone from outside the model domain (O3-INFLOW) and the other half was formed by ozone precursors (O3-PBL) emitted in eastern, central, and southern China. In the O3-PBL, 3.0% of the ozone was from Mt. Huang reflecting the small local contribution (O3-LOC) and the non-local contributions (O3-NLOC) accounted for 41.6%, in which ozone from the southerly regions contributed significantly, for example, 9.9% of the ozone originating from Jiangxi, representing the highest geographical contributor. Because the origin and variation of O3-NLOC was highly related to the diurnal movements in boundary layer, the similar diurnal patterns between O3-NLOC and total ozone both indicated the direct influence of O3-NLOC and the importance of boundary layer diurnal variations in the formation of such distinct diurnal ozone variations at Mt. Huang.

Abstract
Objective: To analyze the correlation between white matter integrity and spatial navigation impairment in patients with mild cognitive impairment (MCI). Methods: A total of 27 MCI subjects and 24 healthy controls were enrolled from the Affiliated Drum Tower Hospital of Nanjing University Medical School from May 2015 to February 2016, who underwent 3.0 T MRI scan and 2D-computer version spatial navigation test.DTI preprocessing and tract-based spatial statistics (TBSS) were performed by PANDA.Two sample t-test and partial correlation coefficients were performed to investigate the correlation of white matter impairments and spatial navigation decline. Results: Relative to controls, MCI showed worse egocentric navigation (t=-2.202, P<0.05). Decreased FA in superior longitudinal fasciculus (left t=2.95, right t=2.95, P<0.05), inferior longitudinal fasciculus and inferior fronto-occipital fasciculus (left t=2.66, right t=2.96, P<0.05), corpus callosum (t=2.09, P<0.05), cingulum (left t=2.76, right t=2.41, P<0.05), fornix (t=4.83, P<0.05), and corticospinal tract (left t=2.33, right t=2.26, P<0.05), were found in the MCI subjects.The decreased FA value of superior longitudinal fasciculus (left r=-0.354, right r=-0.347, P<0.05), inferior longitudinal fasciculus (left r=-0.338, right r=-0.336, P<0.05), cingulum (left r=-0.395, right r=-0.370, P<0.05), right corticospinal tract (r=-0.362, P<0.05) and fornix (r=-0.369, P<0.05) were correlated with increased ego average total error.Allo average total error were negative correlated with FA value of superior longitudinal fasciculus (left r=-0.329, right r=-0.350, P<0.05), inferior longitudinal fasciculus (left r=-0.349, right r=-0.378, P<0.05), splenium of corpus callosum (r=-0.364, P<0.05) and cingulum (left r=-0.340, right r=-0.406, P<0.05). Conclusion: This study implicated the potential white matter structural basis of spatial navigation impairment and will have an impact on the further study of the neurobiological mechanisms of human spatial navigation ability.

Abstract
We demonstrate unrepeatered transmission of 8x128Gb/s PDM-QPSK signals over a 515k-m fiber link. This ultra-long distance of 800 Gb/s unrepeatered transmission in a single fiber configuration is achieved by employing enabling techniques such as large-effective-area ultra-low-attenuation fibers, co-propagating and counter-propagating 2nd-order-pumped distributed Raman amplification, and remote optically pumped amplifier (ROPA). The ROPA itself is also counter-propagating 2nd-order Raman pumped. The designs and characteristics of the ROPA and 2nd-order pumped distributed Raman amplification are described, and optimization of the transmission performance of this ultra-long reach 800Gb/s unrepeatered transmission fiber link is discussed in this paper.

Abstract
Lipases are ubiquitous enzymes in nature, which play a crucial role in fat metabolism by catalyzing the hydrolysis of triacylglycerol to free fatty acids and glycerol. However, reports concerning insect lipase are rare. In this study, we studied the expression and activity of a lipase-related protein from Antheraea pernyi (ApLRP). Recombinant ApLRP was expressed in Escherichia coli cells and used to raise rabbit anti-ApLRP polyclonal antibodies. ApLRP mRNA and protein expression were abundant in the midgut and malpighian tubules, respectively. After challenge with four different microorganisms (E. coli, Beauveria bassiana, Micrococcus luteus and nuclear polyhedrosis virus), the expression levels of ApLRP mRNA in midgut were inducted significantly compared with the control. The different pathogens induced different ApLRP gene expression patterns. The optimum temperature and pH for the enzyme's activity were 35°C and 7.0, respectively. ApLRP activity was stimulated in the presence of Mg2+, Na+, Ca2+ and b-mercaptoethanol; while Zn2+, Cu2+ and Fe3+ inhibited its activity. Detergents such as SDS, glycerol and Tween-20 increased the lipase activity by 20-30%. Our results indicated that ApLRP might play an important role in the innate immunity of insects.

Abstract
Malignant pleural effusion (MPE) is a poor prognostic sign for cancer patients, whereas the functional condition of MPE CD8(+) T cells is unknown. Intracavitary immunotherapy with interleukin (IL)-2 has been proven effective in controlling MPE. To elucidate the underlying mechanism, 35 lung cancer (LC) patients with MPE and 12 healthy donors were included in this study. For the IL-2 therapy experiments, after draining partial MPE, we treated 14 patients by administrating IL-2 (3 or 5 × 10(6) U in 50 ml saline) into the thoracic cavity. Before and after IL-2 treatment (40-48 h), the MPE and peripheral blood (PB) were obtained from the subjects. PB from healthy volunteers was collected as control. The expression of programmed cell death 1 (PD-1), granzyme B (GzmB), interferon (IFN)-γ and the proliferation were analysed in CD8(+) T cells from MPE and PB. The CD8(+) T cells in the MPE of LC patients showed lowest GzmB, IFN-γ and proliferation but highest PD-1 expression, compared with that in PB of LC patients and healthy donors. IL-2 treatment reduced the expression of PD-1, increased the expression of GzmB and IFN-γ and enhanced the proliferation of CD8(+) T cells in MPE. In addition, IL-2 treatment reduced carcino-embryonic antigen (CEA) level in MPE. These results indicate that MPE CD8(+) T cells exhibit exhaustion phenotype which can be reversed by IL-2 therapy.

Abstract
The expression of T-cell antigen receptor (TCR) Vβ genes in autoimmune thyroid diseases (AITDs) was investigated. RNA was extracted from the thyroid tissue of 23 patients with early-stage Graves' disease, 19 patients with late-stage Graves' disease and 20 patients with Hashimoto's disease. Peripheral blood lymphocytes from patients and 20 normal subjects (controls) were analysed in parallel. AITD was found to be associated with diminished TCR Vβ gene family utilization. In addition, AITDs appeared to select for specific TCR Vβ families. The Vβ3, Vβ5 and Vβ8 families were expressed more frequently in thyroid-infiltrating T-lymphocytes of early-stage Graves' disease than other Vβ gene families. Selective expression was not observed in infiltrating T-lymphocytes obtained from thyroid tissue of patients with late-stage Graves' disease or Hashimoto's disease. Preferentially expressed TCR Vβ gene families may be useful as molecular targets for targeted immunotherapy of AITDs.

Abstract
BACKGROUND Psoriasis is a debilitating skin disease associated with substantial pruritus, work impairment, and sleep disturbance. OBJECTIVE This study evaluated associations between pruritus and work productivity, and the role of sleep problems as a possible mediator of the relationship between the two. METHODS AND MATERIALS Data from a pruritus visual analog scale (Itch VAS), the Medical Outcomes Study Sleep Scale (MOS-SS), and the Work Productivity and Activity Impairment Questionnaire (WPAI) were collected in a phase 2 clinical trial in patients with psoriasis treated with ixekizumab or placebo. Mediating effects of sleep were tested in multiple regressions with pruritus severity (independent variable) and work productivity (dependent variable). Sobel tests evaluated the significance of sleep's effect. RESULTS Several MOS-SS domains were significantly associated with the WPAI presenteeism, work productivity, and activity impairment scores, and decreased the effect of pruritus. Sobel tests indicated that the Sleep Problems Index I had a significant effect (P<.05) in mediating the relationship between pruritus and presenteeism, work productivity, and activity impairment. CONCLUSION Sleep may mediate the role of pruritus on work productivity, but both factors appear to have independent negative effects on work.

Abstract
BACKGROUND Previous studies have demonstrated the efficacy of somatic stimulation for patients with gastrointestinal motility disorders. However, little effort has been made to investigate the effects of acupuncture on colonic motility, particularly in pathological conditions. The precise mechanism employed in the regulation of acupuncture on colonic motility still remains unclear. METHODS We assessed the effect of acupuncture at heterotopic acupoints on distal colonic motility using a warm-water-filled manometric balloon inserted 5-6 cm into the rectum of anesthetized normal rats or rats with diarrhea or constipation. Choline chloride, 4-DAMP, cobra venom and capsaicin were separately applied to investigate the role of M3 receptors in the regulation of distal colonic motility by acupuncture at heterotopic acupoints, and whether Aδ- and/or C-fibers are required for triggering distal colonic motility by acupuncture. KEY RESULTS Acupuncture at heterotopic acupoints increased distal colonic motility not only in normal rats but also in rats with constipation or diarrhea. M3 receptors play an important role in the facilitation of distal colonic motility triggered by acupuncture at heterotopic acupoints. Afferent nerve Aδ- and C-fibers mediate the transduction of the acupuncture signal and C-fibers are essential for enhancing the effect of acupuncture at the heterotopic acupoint on distal colonic motility. CONCLUSIONS & INFERENCES Our results reveal that acupuncture at heterotopic acupoints increases distal colonic motility regardless of normal or pathological conditions via predominately activating C-fibers of somatic afferent nerve and M3 receptors.

Abstract
Vibrio anguillarum is the causative agent of vibriosis, a deadly haemorrhagic septicaemic disease affecting various marine and fresh/brackish water fish, bivalves and crustaceans. However, the diversity and virulence mechanisms of this pathogen are still insufficiently known. In this study, we aimed to increase our understanding of V. anguillarum diversity and virulence through comparative genome analysis of 15 V. anguillarum strains, obtained from different hosts or non-host niches and geographical regions, among which 10 and 5 strains were found to be virulent and avirulent, respectively, against sea bass larvae. First, the 15 draft genomes were annotated and screened for putative virulence factors, including genes encoding iron uptake systems, transport systems and non-ribosomal peptide synthetases. Second, comparative genome analysis was performed, focusing on single nucleotide polymorphisms (SNPs) and small insertions and deletions (InDels). Five V. anguillarum strains showed a remarkably high nucleotide identity. However, these strains comprise both virulent and avirulent strains towards sea bass larvae, suggesting that differences in virulence may be caused by subtle nucleotide variations. Clearly, the draft genome sequence of these 15 strains represents a starting point for further genetic research of this economically important fish pathogen.

Abstract
T-cell exhaustion was originally identified during chronic infection in mice, and was subsequently observed in humans with cancer. The exhausted T cells in the tumor microenvironment show overexpressed inhibitory receptors, decreased effector cytokine production and cytolytic activity, leading to the failure of cancer elimination. Restoring exhausted T cells represents an inspiring strategy for cancer treatment, which has yielded promising results and become a significant breakthrough in the cancer immunotherapy. In this review, we overview the updated understanding on the exhausted T cells in cancer and their potential regulatory mechanisms and discuss current therapeutic interventions targeting exhausted T cells in clinical trials.

Abstract
Near-infrared fluorescence (NIRF) molecular imaging holds great promise as a new "point-of-care" medical imaging modality that can potentially provide the sensitivity of nuclear medicine techniques, but without the radioactivity that can otherwise place limitations of usage. Recently, NIRF imaging devices of a variety of designs have emerged in the market and in investigational clinical studies using indocyanine green (ICG) as a non-targeting NIRF contrast agent to demark the blood and lymphatic vasculatures both non-invasively and intraoperatively. Approved in the USA since 1956 for intravenous administration, ICG has been more recently used off label in intradermal or subcutaneous administrations for fluorescence imaging of the lymphatic vasculature and lymph nodes. Herein, we summarize the devices of a variety of designs, summarize their performance in lymphatic imaging in a tabular format and comment on necessary efforts to develop standards for device performance to compare and use these emerging devices in future, NIRF molecular imaging studies.
