Abstract
The American cockroach (Periplaneta americana) is an urban pest with a precise chemosensory system that helps it achieve complex physiological behaviours, including locating food and mating. However, its chemosensory mechanisms have not been well studied. Here, we identified 71 putative odorant carrier protein genes in P. americana, including 57 new odorant-binding proteins (OBPs) and 11 chemosensory proteins (CSPs). To identify their physiological functions, we investigated their tissue expression patterns in antennae, mouthparts, legs, and the remainder of the body of both sexes, and determined that most of these genes were expressed in chemosensory organs. A phylogenetic tree showed that the putative pheromone-binding proteins of P. americana were in different clades from those of moths. Two genes, PameOBP24 and PameCSP7, were expressed equally in antennae of both sexes and highly expressed amongst the OBPs and CSPs. These genes were expressed in Escherichia coli and the resultant proteins were purified. The binding affinities of 74 common odorant compounds were tested with recombinant PameOBP24 and PameCSP7. Both proteins bound a variety of ligands. Our findings provide a foundation for future research into the chemosensory mechanisms of P. americana and help in identifying potential target genes for managing this pest.

Abstract
Objective: To investigate the effect of cannabinoid receptor-2 (CB2) agonist AM1241 on the mRNA and protein expression of platelet-derived growth factor (PDGF) and collagen-III (Col-III) in the liver tissue of mice with experimental liver fibrosis induced by carbon tetrachloride (CCl(4)). Methods: Totally 38 8-week-old male C57BL/6J mice were randomly divided into control group, model group, 3 mg/kg CB2 receptor agonist (AM1241) group, and 9 mg/kg AM1241 group. All mice, except for the control group, were treated with 30% CCl(4) (three times a week, 5 ml/kg body weight, 16 weeks) to establish a liver fibrosis model. Meanwhile, 3 and 9 mg/kg AM1421 was intraperitoneally injected for daily intervention, respectively. The dosage was adjusted according to actual body weight. The same solvent was given in the control group. The serum level of aspartate aminotransferase (AST) was measured by serum enzyme digestion. The liver inflammation and fibrosis were observed by HE staining of tissue slices. The mRNA and protein expression of PDGF and Col-III in hepatic tissue was determined by real-time PCR and immunohistochemistry. Results: Compared with the control group, the mice in model group showed severe liver fibrosis, significantly elevated serum AST level (742 ± 300.8 U/L vs 118.1 ± 31.1 U/L, P < 0.05), and significantly increased mRNA and protein expression of PDGF and Col-III in liver tissue (P < 0.05). Compared with the model group, the mice in 3 mg/kg AM1241 group and 9 mg/kg AM1241 group had less severe liver fibrosis, and significantly reduced serum AST levels (116.6 ± 13.68 U/L vs 742 ± 300.8 U/L, P < 0.05; 113.8 ± 16.01 U/L vs 742 ± 300.8 U/L, P < 0.05) and mRNA and protein expression of PDGF and Col-III in liver tissue (P < 0.05). Conclusion: CB2 receptor agonist AM1241 can inhibit the mRNA and protein expression of PDGF in the liver tissue of mice with hepatic fibrosis, and reduce extracellular matrix synthesis.

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.
