Abstract
In this work, we prepared a novel cancer chemotherapeutic nanocarrier through the self-assembly of a mussel-derived, cancer-targeting peptide with a pH-sensitive conjugation of antitumor drugs. The biomimetic peptide was designed with a fluorescent molecule fluorescein isothiocyanate for imaging, a RGD sequence for cancer-targeting and tetravalent catechol groups for dynamic conjugation of the antitumor drug bortezomib via pH-cleavable boronic acid-catechol esters. Our study demonstrated that the peptide-based prodrug nanocarrier dramatically the enhanced specific cellular uptake and cytotoxicity toward human breast cancer cells in vitro in comparison with free drug and nontargeting control nanoparticles. Likewise, the prodrug nanocarrier showed improved therapeutic efficacy and low systematic toxicity in vivo. Considering highly biomimetic nature of the peptide-based nanocarriers, rapid drug release from the dynamically conjugated prodrugs, and convenience of introducing cancer-targeting activity onto this nanosystem, we believe our work would provide new ideas for the development of intelligent and biocompatible drug delivery systems to improve the chemotherapy efficacy in clinic. Furthermore, the pH-sensitive drug conjugation mechanism on peptide-based nanocarriers would provide a hint for the exploitation of dynamic prodrug strategies and the development of highly biocompatible nanocarriers using biogenic materials, e.g., the proteinogenic nanomaterials decorated with drugs through dynamic covalent chemistry.

Abstract
AIM We aimed to evaluate the association between selective COX-2 inhibitors (coxibs) and the risk of colorectal neoplasms and vascular events with and without low-dose aspirin. METHOD We searched for randomized controlled trials and comparative studies in PubMed, EMBASE and Cochrane Library databases using pertinent key terms. Risk ratios (RRs) were calculated for each study with a fixed- or random-effects model. RESULTS Eight clinical studies with 44 566 subjects were eligible. The use of coxib significantly reduced the overall risk of colorectal neoplasms by 21% (RR = 0.79, 95% CI 0.70-0.89; P = 0.000). The chemopreventive effect of coxibs was beneficial in the first year (RR = 0.74, 95% CI 0.58-0.94; P = 0.013), marginal in the third year (RR = 0.79, 95% CI 0.63-1.01; P = 0.059) and counterproductive in the fifth year (RR = 1.65, 95% CI 1.23-2.21; P = 0.001). Compared with the use of aspirin alone, combined use of coxib and aspirin for 3 years increased the risk of a colorectal neoplasm by 80% in the fifth year (RR = 1.80, 95% CI 1.22-2.66; P = 0.003) but decreased by 79% and 30%, respectively, the risks of cardiovascular thromboembolic events (RR = 1.79, 95% CI 1.33-2.41; P = 0.0001) and renal impairment/hypertension (RR = 1.30, 95% CI 1.09-1.54; P = 0.003) caused by coxib use alone. CONCLUSION Coxibs may reduce the overall risk of colorectal neoplasms, but the chemopreventive effects are attenuated over time. When participants take low-dose aspirin simultaneously, coxibs may not be useful for chemoprevention of colorectal neoplasm.

Abstract
Objective:The aim of this study is to investigate the effect of highly selective branches neurotomy of vidian nerve with low temperature plasma on the level of vasoactive intestinal peptide in nasal mucosa of patients with allergic rhinitis. Method:Fifty patients with allergic rhinitis were selected as the experimental group. At the same time, 50 normal adults in our hospital were selected as the control group. Highly selective branches neurotomy of vidian nerve with low temperature plasma was performed to observe the changes of vascular intestinal peptide levels in patients with nasal mucosa and the clinical efficacy. Result:Fifty patients with allergic rhinitis were treated with highly selective branches neurotomy of vidian nerve with low temperature plasma. 28 cases have significant effect and the curative effect was 64.3%-92.1% (average was 77.4±4.5)%; 19 were effective and the therapeutic effect was 31.2%-56.4%, with an average of (43.2±2.9)%; only 3 cases were ineffective, and the therapeutic effect was less than 30%. There was significant difference between the two groups after treatment (P<0.05). The optical density of vasoactive intestinal peptide was (1 723.3±215.4) and (2 732.3±324.5) in the preoperative and postoperative groups, respectively, with significant differences (P<0.05). The optical density of vasoactive intestinal peptide in the control group was (1 855.4±429.3), which was significantly different from that in the experimental group before operation (P<0.05). The difference between the control group and the experimental group after operation have no statistically significant (P>0.05). Conclusion:Highly selective branches neurotomy of vidian nerve with low temperature plasma can significantly reduce the level of vasoactive intestinal peptide in nasal mucosa of patients with allergic rhinitis, alleviate the symptoms of nasal congestion and paroxysmal sneezing, and improve the prognosis of patients.

Abstract
The impact of climate change on agricultural systems is a major concern as it can have a significant effect on the world food supply. The objective of this study was to evaluate climate change impacts on crop production and nitrate leaching in two distinct climatic zones in Canada. Spring wheat (Triticum aestivum L.) was selected for the semiarid regions of Western Canada (Swift Current, SK) and maize (Zea mays L.) was chosen for the more humid regions of central Canada (Woodslee, ON). Climate scenarios were based upon simulations from a Canadian Regional Climate Model (CanRCM4) under two Representative Concentration Pathways (RCP4.5 and RCP8.5) and crop simulations were conducted using the Decision Support System for Agrotechnology Transfer (DSSAT) model. Compared to the baseline climate scenario, wheat yields increased by 8, 8, 11, 15%, whereas maize yields decreased by 15, 25, 22, 41% under RCP4.5 2050s (2041-2070), RCP4.5 2080s (2071-2100), RCP8.5 2050s and RCP8.5 2080s scenarios, respectively. Annual nitrate leaching increased by 19, 57, 73, 129% at Swift Current and by 84, 117, 208, 317% at Woodslee under the four scenarios, respectively. Adaptation measures suggested that fertilizer N rate for spring wheat should be increased to 80-100 kg N ha-1 to obtain optimal yields although this will result in an additional risk of 5-8 kg N ha-1 nitrate leaching at Swift Current. The fertilizer N rate of 150 kg N ha-1 was found to be suitable for high maize yields at Woodslee. New wheat and maize cultivars with long growing seasons would enable crop growth to match the phenological stage and hence maintain high crop yields to adapt to increased temperatures in the future.

Abstract
OBJECTIVE We aimed at investigating changes in the expression and physiological function of hyperpolarization-activated cyclic nucleotide-gated (HCN) channels in interstitial cells of Cajal (ICC) in diabetic state. MATERIALS AND METHODS Twenty adult female Sprague-Dawley (SD) rats were randomly assigned to control and Zucker diabetic fatty (ZDF) group. The protein and mRNA expression of HCN isoforms and C-kit in the rat bladders were detected using Western blotting and reverse transcription-polymerase chain reaction (RT-PCR). The bladder contraction was evaluated using a bladder smooth muscle strip test. Whole cell patch-clamp techniques were used to detect the activity of HCN channels. Immunofluorescent staining was used to the positive expression of HCN and C-kit in ICC. RESULTS cAMP, as HCN channel-specific stimulant, could increase the frequency and amplitude of spontaneous contractions in both group, while cAMP inducing contraction of ZDF rats, was still significantly lower compared with the control group. Acute bladder ICCs were isolated by collagenase digestion. Classic Ih current pattern was recorded on ICCs while Ih current amplitude of ICCs from ZDF diabetic rats was significantly lower than the control group. The expression and mRNA of HCN1-4 isoforms in ZDF diabetic rats were both significantly lower compared with the control group. Meanwhile, the number of c-kit positive cells in ZDF diabetic rats showed no significant differences compared with controls. The morphological structure of ICC in the bladder of ZDF rats was relatively loose and the number of their cell process was apparently decreased. CONCLUSIONS The structure of ICCs in ZDF rats was relatively loose, their connection to each other was also diminished. The expression of HCN was down-regulated and its response to cAMP was also decreased. HCN channels in bladder ICCs might regulate detrusor contraction. Changes in HCN expression and activity in bladder ICCs might be one of the most important mechanisms of diabetic cystopathy.

Abstract
Objective: To investigate the action and antioxidant effects of CB2 agonist AM-1241 on rat hepatic stellate cell line (HSC-T6). Methods: HSC-T6 was randomly divided into four groups: control group, oxidative stress group, AM-1241 intervention group and AM-1241+AM-630 antagonist group. Survival rate of HSC-T6 was detected by thiazolyl blue assay under 24 h interventions with 0, 20, 50, 80 μmol/L AM-1241 and 0, 10, 20, 30, 40 μmol/L AM-630, respectively. Besides control group, the remaining groups were well cultured in low-glucose DMEM containing 100 mU/L glucose oxidase (GO) for 12 h to prepare the oxidative stress model. Then, AM-1241 intervention group was treated with 50 μmol/L low-glucose DMEM medium. After incubation for 12 h, the AM-1241+AM-630 antagonist group was treated with CB2 antagonist AM-630 (20 μmol/L) for 2 h, and cultured with 50 μmol/L AM-1241 in complete low-glucose medium for 12 h. The optimal drug concentration was selected according to the cell viability considered by the experiment results. Type III collagen (C III) content in the HSC-T6 supernatant was detected by enzyme-linked immunosorbent assay. Glutathione (GSH) content in HSC-T6 was detected by spectrophotometry. CB2 and heme oxygenase-1(HO-1) in each group of HSC-T6 were detected by western blotting. Results: HSC-T6 proliferation was inhibited in each group of AM-1241 in a concentration-dependent manner (P < 0.05). The inhibition was highest at 80μmol/L, and the cell survival rate was (41.61% ± 3.13%) (P < 0.05). AM-630 concentration group had no significant inhibitory effect on the proliferation of HSC-T6 (P > 0.05). HSC-T6 expressed CB2 receptor in each group. The expression level of CB2 in the AM-1241 intervention group was higher compare with control group (P < 0.05).The expression of Col III were significantly higher in oxidative stress group (P < 0.05) than in control group, and the expression of Col III of AM-1241 intervention group was significantly lower than that in oxidative stress group (P < 0.05). Col III level in AM-1241+AM-630 antagonistic group was significantly higher than that in AM-1241 intervention group (P < 0.05). There was no significant difference between AM-1241+AM-630 antagonistic group and oxidative stress group (P > 0.05). The content of GSH and HO-1 in oxidative stress group was higher (P < 0.05) than control group. The content of GSH and HO-1 in the AM-1241 intervention group was higher compared with oxidative stress group, while content of AM-1241 + AM-630 antagonist group was lower compared to AM-1241 intervention group (P < 0.05), and the differences were not statistically significant for oxidative stress group. Conclusion: CB2 agonist AM-1241 can inhibit the proliferation and activation of HSC-T6 and its mechanism may activate the nuclear translocation of Nrf2 binding to HSC-T6, initiating the up-regulation of antioxidant enzymes HO-1 and GSH protein expression, and thus increase the antioxidant effect of HSC-T6.

Abstract
BACKGROUND Intellectual disabilities (IDs) have become a public health concern worldwide, but few studies on rehabilitation service utilisation in this population were conducted in developing countries. We aimed to examine trends and socioeconomic disparities in the utilisation of rehabilitation services among adults with IDs in China. METHODS We obtained data from a population-based survey by using a multistage, randomised, cluster sampling process to ascertain adults with IDs in 2006 and a selected subsample for follow-up surveys during 2007-2013. Psychiatrists ascertained individuals with IDs ascertained by intelligence quotient score under 70, deficits in two or more adaptive behaviours and age of onset under 18 years. RESULTS Overall, the utilisation rate of rehabilitation services significantly increased from 10.1% in 2007 to 33.7% in 2013, with an annual average percentage growth of 34.3% when adjusting for multiple confounders. The mounting trends remained significant in all socioeconomic groups. The growth rates among lower socioeconomic participants were much higher than those among higher socioeconomic participants, and the strength in the association between socioeconomic position (education and region) and rehabilitation service utilisation declined in 2007-2013. CONCLUSIONS This study found an upward trend in rehabilitation service utilisation in Chinese adults with IDs during 2007-2013, and socioeconomic disparities in rehabilitation service use in this population showed a downward trend over time.

Abstract
Objective: To establish an optimized method of recombinase polymerase amplification (RPA) to rapidly detect Pseudomonas aeruginosa in clinic. Methods: (1) The DNA templates of one standard Pseudomonas aeruginosa strain was extracted and detected by polymerase chain reaction (PCR), real-time fluorescence quantitative PCR and RPA. Time of sample loading, time of amplification, and time of detection of the three methods were recorded. (2) One standard Pseudomonas aeruginosa strain was diluted in 7 concentrations of 1×10(7,) 1×10(6,) 1×10(5,) 1×10(4,) 1×10(3,) 1×10(2,) and 1×10(1) colony forming unit (CFU)/mL after recovery and cultivation. The DNA templates of Pseudomonas aeruginosa and negative control strain Pseudomonas putida were extracted and detected by PCR, real-time fluorescence quantitative PCR, and RPA separately. The sensitivity of the three methods in detecting Pseudomonas aeruginosa was analyzed. (3) The DNA templates of one standard Pseudomonas aeruginosa strain and four negative control strains (Staphylococcus aureus, Acinetobacter baumanii, Candida albicans, and Pseudomonas putida) were extracted separately, and then they were detected by PCR, real-time fluorescence quantitative PCR, and RPA. The specificity of the three methods in detecting Pseudomonas aeruginosa was analyzed. (4) The DNA templates of 28 clinical strains of Pseudomonas aeruginosa preserved in glycerin, 1 clinical strain of which was taken by cotton swab, and negative control strain Pseudomonas putida were extracted separately, and then they were detected by RPA. Positive amplification signals of the clinical strains were observed, and the detection rate was calculated. All experiments were repeated for 3 times. Sensitivity results were analyzed by GraphPad Prism 5.01 statistical software. Results: (1) The loading time of RPA, PCR, and real-time fluorescence quantitative PCR for detecting Pseudomonas aeruginosa were all 20 minutes. In PCR, time of amplification was 98 minutes, time of gel detection was 20 minutes, and the total time was 138 minutes. In real-time fluorescence quantitative PCR, amplification and detection could be completed simultaneously, which took 90 minutes, and the total time was 110 minutes. In RPA, amplification and detection could also be completed simultaneously, which took 15 minutes, and the total time was 35 minutes. (2) Pseudomonas putida did not show positive amplification signals or gel positive results in any of the three detection methods. The detection limit of Pseudomonas aeruginosa in real-time fluorescence quantitative PCR and PCR was 1×10(1) CFU/mL, and that of Pseudomonas aeruginosa in RPA was 1×10(2) CFU/mL. In RPA and real-time fluorescence quantitative PCR, the higher the concentration of Pseudomonas aeruginosa, the shorter threshold time and smaller the number of cycles, namely shorter time for detecting the positive amplified signal. In real-time fluorescence quantitative PCR, all positive amplification signal could be detected when the concentration of Pseudomonas aeruginosa was 1×10(1)-1×10(7) CFU/mL. In RPA, the detection rate of positive amplification signal was 0 when the concentration of Pseudomonas aeruginosa was 1×10(1) CFU/mL, while the detection rate of positive amplification signal was 67% when the concentration of Pseudomonas aeruginosa was 1×10(2) CFU/mL, and the detection rate of positive amplification signal was 100% when the concentration of Pseudomonas aeruginosa was 1×10(3)-1×10(7) CFU/mL. (3) In RPA, PCR, and real-time fluorescence quantitative PCR, Pseudomonas aeruginosa showed positive amplification signals and gel positive results, but there were no positive amplification signals or gel positive results in four negative control strains of Acinetobacter baumannii, Staphylococcus aureus, Candida albicans, and Pseudomonas putida. (4) In RPA, 28 clinical strains of Pseudomonas aeruginosa preserved in glycerin and 1 clinical strain of Pseudomonas aeruginosa taken by cotton swab showed positive amplification signals, while Pseudomonas putida did not show positive amplification signal. The detection rate of positive amplification signal of 29 clinical strains of Pseudomonas aeruginosa in RPA was 100%. Conclusions: The established optimized RPA technology for fast detection of Pseudomonas aeruginosa requires shorter time, with high sensitivity and specificity. It was of great value in fast detection of Pseudomonas aeruginosa infection in clinic.

Abstract
Foodborne disease caused by Vibrio parahaemolyticus is a serious public health problem in many countries. Molecular typing has a great scientific significance and application value for epidemiological research of V. parahaemolyticus. In this study, a real-time PCR with melting curve analysis was established for molecular typing of V. parahaemolyticus. Eighteen large variably presented gene clusters (LVPCs) of V. parahaemolyticus which have different distributions in the genome of different strains were selected as targets. Primer pairs of 18 LVPCs were distributed into three tubes. To validate this newly developed assay, we tested 53 Vibrio parahaemolyticus strains, which were classified in 13 different types. Furthermore, cluster analysis using NTSYS PC 2.02 software could divide 53 V. parahaemolyticus strains into six clusters at a relative similarity coefficient of 0.85. This method is fast, simple, and conveniently for molecular typing of V. parahaemolyticus.

Abstract
Fully printed humidity sensors based on two-dimensional (2D) materials are described. Monolayer graphene oxide (GO) and few-layered black phosphorus (BP) flakes were dispersed in low boiling point solvents suitable for inkjet printing. The humidity sensors were fabricated by printing GO and BP sensing layers on printed silver nanoparticle electrodes. The electrical response of the GO and BP sensors to humidity levels ranges from 11 to 97% relative humidity, which revealed a high capacitance sensitivity of 4.45 × 104 times for the GO sensor and 5.08 × 103 times for the BP sensor at 10 Hz operation frequency. Response/recovery times of the GO and BP sensor were found to be 2.7/4.6 s and 4.7/3.0 s respectively. These sensors also showed sensitive and fast response to a proximal human fingertip, showing potential applications in contactless switching.

Abstract
BACKGROUND Adults with intellectual disabilities (ID) often have multiple comorbidities. Psychiatric disorders in this population have been poorly studied in developing countries. We aimed to investigate the prevalence of psychiatric disorders in adults with ID and whether comorbid psychiatric disorders were associated with health service utilisation. METHODS We obtained data from the Second National Sample Survey on Disability, conducted in 31 provinces of China and selected a subsample of 13 631 adults aged 18 years and above with ID. ID were defined by intelligence quotient score under 70, deficits in two or more adaptive behaviours and age of onset under 18 years. Psychiatric disorders were identified according to the International Statistical Classification of Diseases, Tenth Revision. Logistic regressions were used for data analyses. RESULTS The prevalence of psychiatric disorders in adults with ID was 16.7%. The most prevalent type of psychiatric disorder was dementia. Older adults, females, being minorities, urban residents, being literate, low-income groups and having severe ID, were associated with elevated risk of psychiatric disorder among adults with ID. Compared with individuals without psychiatric disorders, those with comorbid psychiatric disorders were more likely to use medical service and less likely to use rehabilitation service. CONCLUSIONS The prevalence of psychiatric disorder in adults with ID was strikingly higher than that in the general population. Health service utilisation among Chinese adults with ID remained a big challenge. There is a possibility of diagnostic overshadowing by local clinicians, which may have resulted in overdiagnosis of dementia and underdiagnosis of common mental disorders. This study informs further investigations regarding common mental disorders among people with ID and has implications for public health strategies and health policies to meet health service need for this population.

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
Objective:To systemically review the therapeutic effect of probitics on allergic rhinitis(AR).Method:Literatures about the effect of probitics on AR were searched in PubMed. The Cochrane Library, Web of Science and CNKI, WanFang Data and VIP inception to April 2016,and 2 reviewers independently screened literatures according to the inclusion and exclusion criteria, extracted data, and assessed the risk of bias of included studies. Then meta-analysis was performed using RevMan5.2 software. Result:A total of 16RCTs involving1374 patients were included in the meta-analysis, including 809 cases in the probitic group and 568 cases in the placebo group. The results of meta-analysis showed that the efficacy of probitic group was superior to the placebo group in total RQLQ,nasal RQLQ,eye RQLQ and the serum eosinophil count,the difference was statistically significant [MD=-4.43,95%CI(-8.65~-0.20);MD=-1.08,95%CI(-1.89~0.27);MD=-0.95,95%CI(-1.46~-1.44);MD=-28.40,95%CI(-43.53~-13.26)].There was no significant difference in Serum IgE between the probitic group and the placebo group(P>0.05).There was no significant difference in the NTSS value between the lactobacillus group and the bifidobacterium group(P>0.05). Conclusion:Compared to the placebo, probitics can effectively reduce symptom scores of patients with AR;and different strains of probitics indicated no significant differences in improving nasal symptoms.
