Abstract
Hand, foot and mouth disease (HFMD) is a serious public health problem. Generally, it is considered that HFMD is mainly caused by enterovirus 71 (EV71) and coxsackievirus A16 (CVA16). Nevertheless, the incidence of HFMD caused by coxsackievirus A6 (CVA6) and coxsackievirus A10 (CVA10) has increased significantly and CVA6 and CVA10 have become major causes of HFMD epidemic. This study develops a duplex real-time reverse transcript polymerase chain reaction (RT-PCR) assay for simultaneous detection of CVA 6 and CVA 10. The specificity, sensitivity, and reproducibility of this assay were analyzed. No cross-reactions with other viruses or false positives were observed. The detection limit of this assay was as low as 11.935 copies for CVA6 and 17.591 copies for CVA10 per reaction (concentration giving a positive duplex real-time RT-PCR result in 95% of samples). The coefficients of variation of the intra- and inter-assay reproducibility for CVA 6 and CVA 10 were both lower than 2%. Our results showed that this duplex real-time RT-PCR assay was a simple, rapid, and cost-effective method for simultaneous identification of CVA6 and CVA10.

End-of-radiation PSA as a novel prognostic factor in patients undergoing definitive radiation and androgen deprivation therapy for prostate cancer. Prostate Cancer Prostatic Dis 2017; 20:203-209.

Abstract
Background In men undergoing definitive radiation for prostate cancer, it is unclear whether early biochemical response can provide additional prognostic value beyond pre-treatment risk stratification. Methods Prostate cancer patients consecutively treated with definitive radiation at our institution by a single provider from 1993–2006 and who had an EOR PSA (n=688, median follow-up 11.2 years). We analyzed the association of an end-of-radiation (EOR) prostate-specific antigen (PSA) level, obtained during the last week of radiation, with survival outcomes. Multivariable-adjusted cox proportional hazards models were constructed to assess associations between a detectable EOR PSA (defined as ≥0.1 ng ml−1) and biochemical failure-free survival (BFFS), metastasis-free survival (MFS), prostate cancer-specific survival (PCSS), and overall survival (OS). Kaplan-Meier survival curves were constructed, with stratification by EOR PSA. Results At the end of radiation, the PSA level was undetectable in 30% of patients. Men with a detectable EOR PSA experienced inferior 10-year BFFS (49.7% vs. 64.4%, p<0.001), 10-year MFS (84.8% vs. 92.0%, p=0.003), 10-year PCSS (94.3% vs. 98.2%, p=0.007), and 10-year OS (75.8% vs. 82.5%, p=0.01), as compared to men with an undetectable EOR PSA. Among NCCN intermediate- and high-risk men who were treated with definitive radiation and androgen deprivation therapy (ADT), a detectable EOR PSA was more strongly associated with PCSS than initial NCCN risk level (EOR PSA: HR 5.89, 95% CI 2.37–14.65, p<0.001; NCCN risk level: HR 2.01, 95% CI 0.74–5.42, p=0.168). Main study limitations are retrospective study design and associated biases. Conclusions EOR PSA was significantly associated with survival endpoints in men who received treated with definitive radiation and ADT. Whether the EOR PSA can be used to modulate treatment intensity merits further investigation.

Abstract
Bacterial LPS is one of the most powerful immunostimulators in nature and causes a wide spectrum of acute pathophysiological effects recognized as toxic properties. At the cellular level, LPS also is cytotoxic for a variety of cells. However, the molecular mechanisms responsible for LPS cytotoxicity are not well understood. In this study, possible mechanisms of LPS cytotoxicity for mouse macrophages were examined in comparison with the effect of detoxified LPS (DeLPS). Mouse peritoneal exudate macrophages cultured with 10 μg/ml of LPS for 48 h evinced approximately 40% cell death as measured by the tetrazolium dye reduction assay. Co-treatment of the macrophages with IFNγ enhanced LPS-associated toxicity so that as little as 0.1 μg/ml of LPS induced a significant toxicity. In contrast, neither DeLPS alone nor the combination of DeLPS and IFNγ induced any cytotoxicity even at a high concentration of DeLPS, such as 100 μg/ml, and a relatively long incubation period such as 72 h. Examination of nitric oxide (NO) production demonstrated a dose-response production of NO in culture supernatants of LPS treated macrophages but not in DeLPS macrophages. However, when the macrophages were primed with IFNγ and stimulated with LPS, more NO production was observed as compared to stimulation with LPS alone. Macrophages were cultured with LPS in the presence of anti-IFNβ; cytotoxicity as well as NO production was significantly reduced. Treatment with the NO inhibitor, NG-monomethyl-L-arginine, completely blocked production of NO and, furthermore, diminished the cytotoxicity induced by either the combination of IFNγ and LPS or LPS alone. Investigation of the possible mechanism of LPS induced cytotoxicity implicated the involvement of apoptosis as shown by DNA fragmentation. Furthermore, treatment with the NO inhibitor completely blocked DNA fragmentation induced by LPS and IFNγ. The data obtained suggest that LPS-induced cytotoxicity of macrophages may be due to apoptosis caused by excessive production of NO.

Abstract
A family of hydrogels based on the crosslinking of bovine serum albumin (BSA) and activated poly(ethylene glycol) (PEG), were characterized. The swelling process was found to be dependent on the molecular weight of the PEG used and on the OH/NH2 molar ratio of the reagents. These hydrogels performed a volume expansion from 266 to 554% when PEG with molecular weights from 3,350 to 20,000 were used. The volume expansion was greater when the OH/NH2 molar ratio increased. Some anisotropy occurred during swelling since thinner devices swelled more than thicker ones, due to the difference of constraints in the hydrogels structure. Mechanical studies showed that these hydrogels were highly deformable and presented good elastic behavior since they broke only after 80% deformation. At this point, they needed a compression force ranging from 165 to 456 g/cm2 to break. The differentiation of two kinds of water in these highly swollen hydrogels was performed using DSC studies at low temperature. Free water (i.e., bulk water) was found to be the predominant form which filled the network, .and bound water (i.e., water engaged in interactions with PEG) tended to form a trihydrate complex (three molecules of water per ethylene oxide repeated unit). Three forms of water with different evaporating rates were detected by DSC studies at high temperature. This other form of water may be important for maintaining the hydrogen's form.

Abstract
Activation of hepatic stellate cells (HSCs) plays an important role in the development of liver fibrosis. The eukaryotic translation initiation factor (eIF) 3a is the largest subunit of the eIF3 complex and has been involved in pulmonary fibrosis. However, the role of eIF3a in liver fibrosis remains largely unknown. Therefore, in this study, we investigated the role of eIF3a in transforming growth factor-β1 (TGF-β1)-induced HSC activation. Our results demonstrated that the expression of eIF3a was up-regulated in human liver fibrotic tissues and activated HSCs. In addition, knockdown of eIF3a suppressed TGF-β-induced HSC proliferation and the expression of α-smooth muscle actin (α-SMA) and collagen I. Furthermore, knockdown of eIF3a inhibited the expression of p-Smad3 induced by TGF-β1 in HSCs. These results suggest that eIF3a may function as a novel regulator to modulate HSC activation, potentially through inhibiting the TGF-β1/Smad3 signaling pathway.

Abstract
Objective:To compare the therapeutic efficacy and the recurrence rate between the simple repositioning method and the reposition manoeuvre plus medication in the treatment of horizontal semicircular canal otolith benign paroxysmal positional vertigo (HSC-BPPV). Method:Sixty-two patients diagnosed with otolith HSC-BPPV by roll maneuver test were randomly divided into canalith repositioning group (32 patients) and reposition plus drug treatment group (30 patients). Patients in the canalith repositioning group were treated only with Barbecue reposition maneuver; patients in the reposition plus drug treatment group were treated firstly with Barbecue reposition maneuver and then were given Alprostadil, Cinepazide and Betahistine drug treatment. Both groups were evaluated after 7 days and 28 days treatment, and the recurrence rate was analyzed after 3 months. Result:After 7 days of the treatment , the recovery rate of the two groups was 62.5% and 73.3%, respectively. There's no significant difference between the two groups. However, the total effective power of the reposition plus drug treatment group was 96.7%, which was significantly higher than that of the canalith repositioning group (75.0%) (χ²=5.858, P<0.05). There were 8 patients in the canalith repositioning group showed changes of BBPV types after treatment, while only 1 patient in the reposition plus drug treatment group showed lesion changes. The difference was statistically significant (χ²=4.061, P<0.05). After 28 days of the treatment, the recovery rate and the total effective power of the two groups was 100%, respectively. There is no statistical difference in the total effective rate between the two groups. After 3 months follow-up, 2 patients in the canalith repositioning group (6.25%) and in the reposition plus drug treatment group (6.67%) showed BBPV recurrence, and no significant difference in the recurrence rate was found between the two groups (P>0.05). Conclusion:The repositioning maneuver is the preferred method for treating HSC BPPV. Canalith reposition maneuver plus medication has no obvious effect on the recovery rate and the recurrence rate, it only increases the effective rate and reduces the changes of the BBPV types.

Abstract
OBJECTIVE To study the genotyping characteristics and antibiotic resistance of methicillin-resistant Staphylococcus aureus(MRSA) isolated from lower respiratory tract at 2 different level hospitals in Shanghai. METHODS The subjects included 155 patients at Ruijin Hospital and Tongren Hospital between January 2013 and June 2014, including 108 males and 47 females, with a mean age of 67.8±16.5. The 155 MRSA strains were isolated from lower respiratory tract specimens and multilocus sequence typing (MLST) and spa typing were analyzed by the PCR method. The antimicrobial resistance of MRSA was tested by VITEK-32. Fisher's exact test was used for statistical analysis. RESULTS Among the 155 strains, 28 MLST-spa molecular types were identified, of which ST764-t002(41.29%), ST239-t037(17.42%) and ST239-t030(10.32%) were the most predominant types. The MRSA strains were susceptible to linezolid, vancomycin and teicoplanin, and also had a lower resistance to trimethoprim-sulfamethoxazole and rifampin, with a susceptible rate of 83.9% and 83.2% respectively, but were highly resistant to other antibiotics. The resistance rate of ST239-t037 to trimethoprim-sulfamethoxazole was higher than that of other types, and the resistance rate of ST239-t030 to rifampin was higher than that of other types, the differences being significant(P<0.001). The mean length of hospital stay of the 155 patients was (97±84) days, and mechanical ventilation were used in 78(50.3%) patients, while 108(69.7%))patients received invasive procedures. Broad-spectrum antibiotics were used in 136 (87.1%) patients. There were differences in age, hospitalization days, smoking history, history of COPD, mechanical ventilation, and operation between the 2 hospitals(P<0.05). CONCLUSION Most of the MRSA strains at Ruijin Hospital and Tongren Hospital between January 2013 and June 2014 were multi-drug resistant, and the susceptibility spectrum of different genotypes was different.

Abstract
Cryptolestes ferrugineus (Stephens, 1831) is an important insect pest of stored products. Due to its broad host range, short life cycle, and high reproductive capacity, this species has rapidly colonized temperate and tropical regions around the world. In this study, we isolated 18 novel polymorphic microsatellite loci from an enriched genomic library based on a biotin/streptavidin capture protocol. These loci will be useful tool to better understand the genetic structure and migration patterns of C. ferrugineus throughout the world. The genetic parameters were estimated based on 80 individual C. ferrugineus from two natural populations. The results revealed that 18 loci were different polymorphic levels. The numbers of alleles ranged from 3 to 12, and eleven loci demonstrated polymorphic information contents greater than 0.5. The observed (H O) and expected (H E) heterozygosities ranged from 0.051 to 0.883 and 0.173 to 0.815, respectively. Five locus/population combinations significantly deviated from Hardy-Weinberg equilibrium. We also demonstrated the potential utility of the C. ferrugineus microsatellites as population and species markers for four additional Cryptolestes species.

Abstract
OBJECTIVE To explore the clinical value of intraoperative magnetic resonance imaging (iMRI) coregistration combined with position emission tomography/computed tomography (PET/CT) in stereotactic brain biopsy. METHODS Forty nine patients with intracranial lesions were operated by stereotactic biopsy from June 2010 to June 2015 in Tianjin Medical University General Hospital. Seventeen patient's operation was guided by iMRI only (group A), thirty two patients' operation was guided by iMRI and PET/CT (group B). The diagnosis success rate and operation related complications were compared between the two groups. RESULTS PET/CT and iMRI were integrated successfully in all cases of group B. Fourteen patients (82.4%) of group A and all 32 patients (100%) of group B had final diagnosis confirmed by histopathological and immunohistochemical observation. The diagnosis success rate of group B was higher than group A (P<0.05). There were 5 patients in total who had postoperative complication, 2 (11.8%) in group A and 3 (9.3%) in group B, but the difference was not statistically significant. CONCLUSIONS PET/CT based metabolic imaging can be automatically integrated with standard MRI guided stereotactic biopsy. Compared with iMRI only, the combined treatment improves diagnosis success rate without increasing complications; it's safe, and has high clinical efficacy.

Abstract
The acidic leucine-rich nuclear phosphoprotein 32B (ANP32B) is reported to impact normal development, with Anp32b-knockout mice exhibiting smaller size and premature aging. However, its cellular and molecular mechanisms, especially its potential roles in tumorigenesis, remain largely unclear. Here, we utilize 'knockout' models, RNAi silencing and clinical cohorts to more closely investigate the role of this enigmatic factor in cell proliferation and cancer phenotypes. We report that, compared with Anp32b wild-type (Anp32b+/+) littermates, a broad panel of tissues in Anp32b-deficient (Anp32b−/−) mice are demonstrated hypoplasia. Anp32b−/− mouse embryo fibroblast cell has a slower proliferation, even after oncogenic immortalization. ANP32B knockdown also significantly inhibits in vitro and in vivo growth of cancer cells by inducing G1 arrest. In line with this, ANP32B protein has higher expression in malignant tissues than adjacent normal tissues from a cohort of breast cancer patients, and its expression level positively correlates with their histopathological grades. Moreover, ANP32B deficiency downregulates AKT phosphorylation, which involves its regulating effect on cell growth. Collectively, our findings suggest that ANP32B is an oncogene and a potential therapeutic target for breast cancer treatment.

Abstract
BACKGROUND The current evidence implicates that psychosocial stress, especially pregnancy-specific stress, is associated with the risk of spontaneous preterm birth. The aim of the present study was to determine the effect of pregnancy-specific stress on spontaneous preterm birth among Chinese people. MATERIALS AND METHODS A total of 2,189 pregnant women were enrolled and followed up until parturition from February 2011 to January 2012. Maternal pregnancy-specific stress was assessed using the revised Pregnancy Stress Rating Scale (PSRS) at third trimester in pregnancy. Socio-demographic and psychological data were collected through interviews, medical, and obstetrical examination records. RESULTS High levels of maternal pregnancy-specific stress during the third trimester increased risk of spontaneous preterm birth compared with the low and medium levels (adjusted risk ratios, 2.92; 95% confidence interval, 1.12-7.58). The first stressor from the revised PSRS includes a risk factor for the safety of infants. CONCLUSIONS High level of pregnancy-specific stress in third trimester might predict spontaneous preterm birth.

Abstract
We investigated the association between polymorphisms in the adiponectin gene (APM-1) and atherosclerotic cerebral infarction (ACI) in a Chinese Han population of Hainan Province. Polymerase chain reaction-restriction fragment length polymorphism and gene sequencing were used to analyze the distribution of APM-1 +45T/G and +276G/T genotypes and their alleles in 120 ACI patients and 120 healthy controls. No statistical correlation was found in the frequency and distribution of the genotype 45T/G between the ACI group and the control group. Genotypic frequencies of GG, GT, and TT at the APM-1 +276 locus were 70.0% (84/120), 25.0% (30/120), and 5.0% (6/120), respectively, in the ACI group, while these values were 52.5% (63/120), 37.5% (45/120), and 10.0% (12/120), respectively, in the control group. The frequency of the G allele was 82.5% (198/240) in the ACI group and 71.25% (171/240) in the control group. The T allele frequency was 17.5% (42/240) in the ACI group and 28.75% (69/240) in the control group. Polymorphisms at the APM-1 -276 locus in the case-controlled groups showed significant differences in the genotype distribution and al-lele frequency between the 2 groups (P = 0.041). The occurrence of ACI in the Hainan Chinese Han population may be associated with +276G/T polymorphisms but not with +45T/G polymorphisms in the APM-1 gene.

Abstract
Although many studies on lepidopteran pheromone-binding proteins (PBPs)/ general odorant-binding proteins (GOBPs) have been reported, the functional differentiation within and between the two odorant-binding protein (OBP) subclasses is still elusive. Here we conducted a comparative study on three SexiPBPs and two SexiGOBPs in Spodoptera exigua. Results showed that all five SexiPBP/GOBP genes have the same intron numbers and conserved exon/intron splice sites. Reverse transcription PCR results showed that these five SexiPBP/GOBPs were primarily expressed in antennae of both sexes and some were also detected in other tissues. Further, quantitative real-time PCR showed that five SexiPBP/GOBPs had different sex-biased expression patterns, with PBP1 being highly male-biased (5.96-fold difference) and PBP3 slightly female-biased (2.43-fold difference), while PBP2 and two GOBPs were approximately sex-equivalent (the absolute value<1.90-fold difference). Binding assays showed that all three SexiPBPs could bind all six sex pheromone components, but SexiPBP1 had much higher affinities [dissociation constant (Ki ) <1.10 μM] than did the other two SexiPBPs (Ki >1.20 μM). Very intriguingly, SexiGOBP2 displayed even stronger binding to five sex pheromone components (Ki <0.40 μM) than SexiPBP1. In contrast, SexiGOBP1 only exhibited weak binding to three alcohol-pheromone components. Similar results were obtained for tested pheromone analogues. In addition, each of SexiPBP/GOBPs selectively bound some plant odorants with considerable affinities (Ki <10.0 μM). Taken together, of the three SexiPBPs, SexiPBP1 may play the most important role in female sex pheromone reception, and additionally all three SexiPBPs can detect some plant odorants, while SexiGOBP2 may be involved in the detection of female sex pheromones in addition to plant odorants. The results strongly suggest functional differentiation within and between the two OBP sub-classes.
