Abstract
The COVID-19 pandemic has resulted in over 772 million confirmed cases, including nearly 7 million deaths, according to the World Health Organization (WHO). Leveraging rapid development, accelerated vaccine approval processes, and large-scale production of various COVID-19 vaccines using different technical platforms, the WHO declared an end to the global health emergency of COVID-19 on May 5, 2023. Current COVID-19 vaccines encompass inactivated, live attenuated, viral vector, protein subunit, nucleic acid (DNA and RNA), and virus-like particle (VLP) vaccines. However, the efficacy of these vaccines is diminishing due to the constant mutation of SARS-CoV-2 and the heightened immune evasion abilities of emerging variants. This review examines the impact of the COVID-19 pandemic, the biological characteristics of the virus, and its diverse variants. Moreover, the review underscores the effectiveness, advantages, and disadvantages of authorized COVID-19 vaccines. Additionally, it analyzes the challenges, strategies, and future prospects of developing a safe, broad-spectrum vaccine that confers sufficient and sustainable immune protection against new variants of SARS-CoV-2. These discussions not only offer insight for the development of next-generation COVID-19 vaccines but also summarize experiences for combating future emerging viruses.

Abstract
Ulcerative colitis-colorectal cancer (UC-CRC) is one of the most serious complications in patients with ulcerative colitis (UC), with worse prognosis and higher mortality than sporadic colorectal cancer (CRC). Since most UC-CRC developed through the "inflammation-dysplasia-carcinoma" approach, early detection of dysplasia through identification of high-risk groups reasonable monitoring and active prevention are extremely important. However, there is no consensus on the risk factors of UC carcinogenesis and the drugs that can be used for chemoprevention currently. This article combined with relevant literature at home and abroad, reviewed the current risk factors and chemopreventive drugs for UC carcinogenesis, in order to provide reference for early prevention, early detection and early diagnosis of UC-CRC.

Abstract
Objective: To investigate the predicting value of different risk prediction models for short-term death in patients with ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock and treated with extracorporeal membrane oxygenation (ECMO). Methods: This study was a retrospective case-control study. Forty patients with STEMI complicated by cardiogenic shock who hospitalized in the First Affiliated Hospital of Zhengzhou University from April 2017 to August 2021 and treated with percutaneous coronary intervention (PCI) and ECMO, were enrolled in this study. Patients were divided into survival group and death group according to their clinical outcomes at 30 days after ECMO implantation, and clinical data of the two groups were collected and analyzed. Receiver operating characteristic (ROC) curve and decision curve analysis (DCA) were used to compare the predictive value of ACEF, AMI-ECMO, Encourage and SAVE risk scores for mortality at 30 days after ECMO implantation. According to the evaluation results of DCA, the optimal risk score was selected. Kaplan-Meier curve estimating the 30-day survival after ECMO implantation was plotted by grouping risk scores with reference to previous literatures. Results: A total of 40 patients with STEMI combined with cardiogenic shock were included, age was (57.4±16.7) years, 31 (77.5%) patients were male, there were 21 (52.5%) patients in the death group and 19 (47.5%) in the survival group. Compared with the survival group, patients in the death group had higher lactic acid values, higher proportion of anterior descending artery or left main artery lesions, and a higher proportion of acute renal failure and continuous renal replacement therapy during hospitalization (all P<0.05). Compared with survival group, ACEF, AMI-ECMO and Encourage scores were higher in death group, SAVE score was lower in death group (all P<0.05). The ROC curve analysis showed that the area under the curve (AUC) of ACEF, AMI-ECMO, Encourage and SAVE scores in predicting mortality were 0.707, 0.816, 0.757, and 0.677 respectively (P>0.05). ACEF score demonstrated the highest sensitivity (90.5%) and Encourage score exhibited the highest specificity (89.5%). DCA indicated that the AMI-ECMO and Encourage scores had the best performance in predicting the 30-day mortality after ECMO therapy. Kaplan-Meier survival curve analysis showed that the 30-day mortality after ECMO implantation increased with the increase of AMI-ECMO and Encourage scores (log-rank P≤0.001). Conclusions: The 4 scoring systems are all suitable for predicting 30-day mortality after VA-ECMO therapy in patients with ST-segment elevation myocardial infarction complicated by cardiogenic shock. Among them, AMI-ECMO and Encourage scores have better predicting performance.

Abstract
Bacterial flagellin is a potent powerful adjuvant, which exerts its adjuvant activity by activating the Toll-like receptor 5 (TLR5) signaling pathway to induce host pro-inflammatory responses. Flagellin of Salmonella typhimurium (S. typhimurium) has shown strong adjuvant effects for a variety of vaccine candidates, however, the adjuvanticity of different serotypes of Escherichia coli (E. coli) flagellin (FliC) is unclear. To explore the adjuvant activity of different serotypes of E. coli flagellin, FliCH1, FliCH7, and FliCH19 recombinant flagellins were prokaryotically-expressed and purified. The adjuvanticity of three recombinant flagellins was evaluated by analyzing their abilities to induce the IL-8 production in human colorectal adenocarcinoma (Caco-2) cells and the immune responses to co-administrated FaeG antigen in mice. Sequence analysis showed that the N-and C-terminal regions are highly conserved, whereas the central region is hypervariable. The TLR5 recognized site is identical among these three serotypes of flagellins. Coomassie blue staining SDS-PAGE showed the molecular mass of FliCH1, FliCH7, and FliCH19 recombinant flagellin are 66 kDa, 64 kDa, and 68 kDa, which can be recognized by anti-FliCH1, FliCH7, and FliCH19 serum, respectively. Moreover, the flagellin serotypes induced similar levels of IL-8 and TNF-α production in Caco-2 cells, anti-FaeG specific IgG antibodies in mice, and IL-4 production in mice spleen cells. Our results indicated that E. coli flagellins can be an adjuvant for vaccine candidates and that different serotypes of E. coli flagellins possess identical adjuvant effects.

Abstract
PURPOSE The long noncoding RNA LINC00261 was reported to be involved in carcinogenesis and has been validated as a tumor suppressor in pancreatic cancer (PC); however, how LINC00261 is regulated has not been fully examined. Here, we attempted to investigate the upstream and downstream targets of LINC00261 in PC. METHODS LINC00261 expression in PC tissues was examined by the Gene Expression Omnibus (GEO) datasets and the Gene Expression Profiling Interactive Analysis (GEPIA) database. The quantitative reverse transcription polymerase chain reaction (qRT-PCR) assays were performed to detect the expression level of LINC00261 in PC cells. The location of LINC00261 in PC cells was identified by RNA fluorescence in situ hybridization (RNA-FISH). Cell Counting Kit-8 (CCK-8), cell apoptosis assay, transwell invasion and migration assays testified the critical role of LINC00261 in PC. The luciferase reporter assay was applied to confirm the binding of LINC00261 to its upstream transcription factor KLF13. The changes in LINC00261 related target protein levels were analyzed by Western blotting assay. RESULTS LINC00261 was significantly lower in PC tissues and was mainly concentrated in the nucleus. Overexpression of LINC00261 inhibited the invasion and migration of PC cells. Mechanistically, transcription factor KLF13 was confirmed to inhibit the epithelial-mesenchymal transition (EMT) process of PC cells by promoting the transcription of LINC00261 and suppressing the expression of metastasis-associated proteins, such as matrix metalloproteinase MMP2 and vimentin, thus inhibiting the metastasis of PC. CONCLUSION LINC00261 regulates PC cell metastasis through the "KLF13-LINC00261-mTOR-P70S6K1-S6" signaling pathway, which provides a significant set of potential PC therapeutic targets.

Abstract
Objective: To evaluate the efficacy within the first 24 h post extracorporeal membrane pulmonary oxygenation (ECMO) and the impact of early efficacy on the prognosis of adult patients with fulminant myocarditis (FM). Methods: This retrospective case analysis study included hospitalized patients (age≥18 years) who were diagnosed with fulminant myocarditis from November 2016 to May 2021 in the First Affiliated Hospital of Zhengzhou University. Patients were divided into survival or non-survival groups according to treatment outcomes. The age, sex, treatments, drug use, ECMO use, clinical and laboratory data (before and 24 h after the use of ECMO) were analyzed. The change rate of clinical and laboratory data after 24 h use of ECMO was calculated to find differences between two groups. Multivariate logistic regression was used to analyze the related factors with in-hospital death and complication between the two groups. Results: A total of 38 FM patients treated with ECMO were included. There were 23 cases (60.5%) in the survival group, aged (39.6±13.7) years, and 17 (73.9%) cases were female. The total ECMO time was (134.4±71.3)h. There were 15 cases (39.5%) in non-survival group, aged (40.0±15.8) years, and there were 12(80.0%) female, the ECMO time was (120.1±72.4) h in this group. The proportion of tracheal intubation and continuous renal replacement therapy in the survivor group and dosage of norepinephrine within 24 h after ECMO implantation were significantly less than in non-survival group (all P<0.05). There was no significant difference in all efficacy related biochemical indexes between two groups before ECMO use. The levels of lactic acid, procalcitonin, creatinine, alanine aminotransferase, aspartate aminotransferase, creatine kinase-MB, cardiac troponin I and N-terminal B-type natriuretic peptide prosoma were significantly less in survival group than in non-survival group at 24 h after the use of ECMO (all P<0.05). Results of multivariate logistic regression analysis showed that the higher 24 h change rate of creatinine (OR=0.587, 95%CI 0.349-0.986, P=0.044) and creatine kinase-MB (OR=0.177, 95%CI 0.037-0.841, P=0.029) were positively correlated with reduced risk of in-hospital mortality. The central hemorrhage and acute kidney injury in survival group were less than in non-survivor group (P<0.05). Conclusions: After 24 h early use of ECMO in FM patients, the improvement of various efficacy related biochemical test indexes in the survival group was better than that in the non-survival group. Faster reduction of creatine kinase-MB and creatinine values within 24 h ECMO use is positively correlated with reduced risk of in-hospital mortality in adult patients with FM.

Abstract
OBJECTIVES Implementation of EUCAST susceptibility testing in an Australian hospital laboratory demonstrated higher rates of aminopenicillin and amoxicillin/clavulanate resistance in Haemophilus influenzae than previously recognized. This study aimed to better define the variability in the detection of β-lactam resistance based on EUCAST and CLSI disc diffusion (DD) methodology, by comparison with the recommended reference method, broth microdilution (BMD), and by concordance with genomic analysis. METHODS A total of 100 random H. influenzae isolates were assessed for ampicillin and amoxicillin/clavulanate susceptibility by EUCAST and CLSI DD and BMD. WGS was used to analyse the ftsI gene of a subset of isolates with β-lactam resistance, other than that due to isolated β-lactamase production. RESULTS Of the 100 isolates, 32 were categorized as either β-lactamase negative, ampicillin resistant (BLNAR) (n = 18) or β-lactamase positive, amoxicillin/clavulanate resistant (BLPACR) (n = 14) by EUCAST DD. All 18 EUCAST BLNAR isolates were genotypically confirmed by WGS. Five of 18 BLNAR isolates were concordant by CLSI DD, 12 by EUCAST BMD and 4 by CLSI BMD. Nine of 14 EUCAST BLPACR isolates were confirmed by WGS; the remaining 5 were 1 mm below the EUCAST DD breakpoint. Only one isolate was detected as BLPACR by CLSI DD. Group III mutations associated with high-level ampicillin resistance were identified in 10/32 isolates. CONCLUSIONS The EUCAST DD susceptibility method is more reliable than either CLSI or BMD for the detection of genotypically defined BLNAR resistance. However, accurate categorization of amoxicillin/clavulanate resistance remains problematic. Continuous and reproducible surveillance of resistance is needed; for this to be possible, robust susceptibility methods are required.

Abstract
Fimbriae-mediated initial adherence is the initial and critical step required for enterotoxigenic Escherichia coli (ETEC) infection. Therefore, vaccine candidates have been developed that target these fimbriae and induce specific anti-fimbriae antibodies to block initial ETEC attachment. While this vaccine effectively protects against ETEC-associated post-weaning diarrhea (PWD), developing a broadly effective vaccine against initial ETEC attachment remains a challenging problem, owing to the immunological heterogeneity among these antigens. Here, we applied multi-epitope fusion antigen (MEFA) technology to construct a FaeG-FedF-FanC-FasA-Fim41a MEFA using the adhesive subunits of predominant fimbriae K88 and F18 as the backbone, which also integrated epitopes from adhesive subunits of the rare fimbriae K99, 987P, and F41; we then generated a MEFA computational model and tested the immunogenicity of this MEFA protein in immunized mice. We next evaluated the potential of the fimbriae-targeted MEFA as a vaccine candidate to effectively prevent PWD using in vitro assessment of its anti-fimbriae, antibody-directed inhibition of bacterial adherence. Computational modeling showed that all relevant epitopes were exposed on the MEFA surface and mice subcutaneously immunized with the MEFA protein developed IgG antibodies to all five fimbriae. Moreover, anti-fimbriae antibodies induced by the MEFA protein significantly inhibited the adhesion of K88+, F18+, K99+, 987P+, and F41+ ETEC strains to piglet small intestinal IPEC-1 and IPEC-J2 cell lines. Taken together, these results indicate that FaeG-FedF-FanC-FasA-Fim41a MEFA protein induced specific anti-fimbriae neutralizing antibodies against the five targeted fimbriae. Critically, these results show the potential of fimbriae-targeted MEFA and indicate their promise as a broad, effective vaccine against PWD.

Abstract
PURPOSE Before biologic and targeted synthetic disease-modifying antirheumatic drug (b/tsDMARD) treatment, latent tuberculosis infection (LTBI) screening by tuberculin skin test (TST) or interferon gamma release assay (IGRA) is recommended. However, both tests have reduced reliability in immunosuppressed patients. We investigated whether dual LTBI screening with both tests could reduce the incidence of tuberculosis. METHODS Consecutive patients receiving b/tsDMARDs for rheumatic diseases in a regional hospital were recruited. All patients underwent either TST/IGRA or both. They were categorised into a single or dual testing group and were followed up for at least 6 months. Isoniazid was prescribed if any one test was positive. RESULTS In total, 217 patients were included in this study; 121 underwent single LTBI testing and 96 underwent dual testing. Tuberculosis occurred in nine patients in the single testing group and one patient in the dual testing group (7.4% vs 1.0%, P=0.045). However, the difference was not statistically significant when follow-up duration was considered (log rank test). In total, 71 patients tested positive for LTBI with isoniazid treatment (28.9% in the single testing group and 45.8% in the dual testing group, P=0.007). Agreement between the IGRA and TST was 74.4% (Cohen's kappa=0.413); agreement was lower in patients receiving prednisolone. Infliximab use was independently associated with tuberculosis (P=0.032). Mild isoniazid-related side-effects occurred in seven patients. CONCLUSIONS Dual LTBI testing with both TST and IGRA is effective and safe. It might be useful for patients receiving prednisolone at the time of LTBI screening, or if infliximab therapy is anticipated.

Abstract
Marine protected areas (MPAs) are increasingly implemented as a conservation tool worldwide. In many cases, they are managed adaptively: the abundance of target species is monitored, and observations are compared to some model-based expectation for the trajectory of population recovery to ensure that the MPA is achieving its goals. Most previous analyses of the transient (short-term) response of populations to the cessation of fishing inside MPAs have dealt only with gonochore (fixed-sex) species. However, many important fishery species are protogynous hermaphrodites (female-to-male sex-changing). Because size-selective harvest will predominantly target males in these species, harvesting not only reduces abundance but also skews the sex ratio toward females. Thus the response to MPA implementation will involve changes in both survival and sex ratio, and ultimately reproductive output. We used an age-structured model of a generic sex-changing fish population to compare transient population dynamics after MPA implementation to those of an otherwise similar gonochore population and examine how different features of sex-changing life history affect those dynamics. We examined both demographically open (most larval recruitment comes from outside the MPA) and demographically closed (most larval recruitment is locally produced) dynamics. Under both scenarios, population recovery of protogynous species takes longer when fishing was more intense pre-MPA (as in gonochores), but also depends heavily on the mating function, the degree to which the sex ratio affects reproduction. If few males are needed and reproduction is not affected by a highly female-biased sex ratio, then population recovery is much faster; if males are a limiting resource, then increases in abundance after MPA implementation are much slower than for gonochores. Unfortunately, the mating function is largely unknown for fishes. In general, we expect that most protogynous species with haremic mating systems will be in the first category (few males needed), though there is at least one example of a fish species (though not a sex-changing species) for which males are limiting. Thus a better understanding of the importance of male fish to population dynamics is needed for the adaptive management of MPAs.

Abstract
Objective: To investigate the mortality of colorectal cancer and its trend from 1999 to 2015 in Tianjin, China, and to explore the mortality features in different populations in order to provide data for prevention and control strategies of colorectal cancer. Methods: Colorectal cancer mortality data between 1999 and 2015 were collected from Tianjin population - based mortality surveillance system maintained by the Tianjin Centers for Disease Control and Prevention (CDC). Population data of permanent residents were collected from Tianjin Municipal Public Security Bureau. The number of new cases and deaths, incidence [including crude incidence, age-adjusted standardized incidence and 95% confidence interval (95% CI)], and mortality (including crude mortality, age-adjusted standardized mortality and 95% CI) of colorectal cancer were calculated. Standardized incidence and mortality of colorectal cancer were calculated using the Segi's world standard population, adjusted with age and gender. JoinPoint regression and Cochran-Armitage trend test were used to determine the statistical significance of differences in mortality trend. Results: A total of 31 376 new onset cases and 14 893 death cases of colorectal cancer were observed in Tianjin from 1999 to 2015. Colorectal cancer incidence increased from 1999 to 2015 with a standardized rate from 9.66/100 000 to 15.36/100 000 [annual percent change(APC)=3.48%, Z=23.21, P<0.001]. Colorectal cancer mortality increased from 1999 to 2015 with a standardized rate from 5.18/100 000 to 6.11/100 000 (APC=1.24%, Z=5.69, P<0.001). Both showed an increasing trend. The death proportion of colon cancer increased (39.67% in 1999 and 50.33% in 2015), while the death proportion of rectal caner decreased (60.33% in 1999 and 48.57% in 2015). The median age of colorectal cancer onset fluctuated steadily around 66 years old (APC=0.16, T=1.75, P=0.100); the median age of death increased from 69 to 73 years old (APC=0.43, T=8.81, P<0.001). From 1999 to 2015, the mortality of colorectal cancer showed a downward trend (all P<0.05) in the age groups of <35 and 35-44 years, while an upward trend (all P<0.05) in the age groups of 45-54 years, 55-64 years and ≥ 65 years. Colorectal cancer mortality in males increased with a standardized rate of 5.53/100 000 in 1999 to 7.33/100 000 in 2015(APC=2.29%, Z=7.86, P<0.001), while colorectal cancer mortality in females flatted with a standardized rate of 4.83/100 000 in 1999 to 4.89/100 000 in 2015 (APC=0.10%, Z=-0.30, P=0.752). Colorectal cancer mortality increased with a standardized rate of 6.75/100 000 in 1999 to 7.33/100 000 in 2015 (APC=0.54%, Z=1.98, P=0.048) in urban areas and of 3.18/100 000 in 1999 to 4.38/100 000 in 2015 (APC=2.47, Z=6.46, P<0.001) in rural areas, whose differences were significant. Standardized mortality rate in rural area was lower but the rising velocity was faster as compared to urban area. Conclusions: Crude mortality and standardized mortality of colorectal cancer increase from 1999 to 2015 in Tianjin population. The people of elder, male and urban area have higher mortality. The mortality in people of male and rural area presents a faster rising state. Further efforts to reduce colorectal cancer mortality in Tianjin are needed to prevention and control of colorectal cancer.

Abstract
4547 Background: Patients (pts) with mUC with FGFR3 mutations who have failed platinum-based chemotherapy have a poor prognosis. Their response to immune checkpoint inhibitors appears diminished 10% or less compared to WT pts. 20% of mUC pts harbor FGFR3 mutations or fusions (M/F). Vofatamab is a fully human monoclonal antibody against FGFR3 that blocks activation of the wildtype and genetically activated receptor. FIERCE-21 is a Phase 1b/2 study designed to evaluate vofatamab monotherapy (VFM) or in combination with docetaxel (VFD). Methods: The P2 expansion enrolled mUC pts with FGFR3 M/F+ tumor (identified with FoundationONE CDx™), who failed ≥ 1 prior line of chemotherapy (including prior taxane for pts receiving VFM) or recurred ≤ 12 months of (neo)adjuvant chemotherapy. Pts had measurable disease and ECOG ≤ 1. Treatment consisted of vofatamab at 25 mg/kg alone and in combination with docetaxel at 75 mg/m2 q3w. Efficacy was assessed by investigators (RECIST 1.1). Primary objectives were safety and objective response-rate (ORR). Results: In the P2, 21 pts each received VFM and VFD. 57% of VFD pts had received at least 2, and 71% of VFM at least 3 prior lines of therapy. Best response to prior therapy was PD for 67% of VFD and 38% of VFM. The safety profile is consistent with previously reported data. TEAEs occurring in > 20% of pts were decreased appetite, diarrhea, pyrexia, asthenia, anemia, dyspnea, and fatigue. Most common vofatamab-related TEAEs in > 10% of pts were asthenia, diarrhea, decreased appetite and rash; all were Grade 1 or 2. In VFM, only 1 pt had a grade 3 TEAE and no pt discontinued treatment due to an AE. There were no cases of hyperphosphatemia, ocular or nail toxicity; 1 pt reported grade 2 skin toxicity. For pts receiving VM, median age was 70 yrs, ECOG 1 = 67%, Hgb < 10 g/dL 5%, liver metastases 19%. Responses have been seen in 7 pts to date including those receiving both VFM and VFD. Conclusions: Vofatamab both alone and combined with D in a q3w schedule are well tolerated with a low frequency of grade 3 TEAEs. Both VFM and VFD have demonstrated efficacy in terms of ORR. PFS/OS and DOR data will be presented at 7+ months for VFD and 9+ months for VFM. Clinical trial information: NCT02401542.

Abstract
409 Background: Patients (pts) with mUC who have failed platinum-based chemotherapy have a poor prognosis. About 20% of them usually respond to immune checkpoint inhibitors (ICI). Also, 20% of pts with mUC harbor FGFR3 mutations or fusions (M/F), and this feature may be associated with lower sensitivity to ICI. Vofatamab (B-701) is a fully human monoclonal antibody against FGFR3 that blocks activation of the wildtype and genetically activated receptor. FIERCE-21 is a Phase 1b/2 study designed to evaluate vofatamab monotherapy (VM) or in combination with docetaxel (VD). Methods: The study consists of a P 1b lead-in (P1b with VD), previously reported followed by P2 expansion cohort in FGFR3 M/F+ pts (identified with the FoundationONE CDx™ assay on archival samples). The study enrolled mUC pts with failure to ≥ 1 line prior chemotherapy (including prior taxane treatment) or ≤12 months of (neo)adjuvant chemotherapy, measurable disease and ECOG ≤ 1. Treatment consisted of vofatamab at 25 mg/kg alone (VM) and in combination with D (VD) at 75 mg/m2 q3w. Efficacy was assessed by investigators (RECIST 1.1). Primary objectives were safety and activity (objective response-rate [ORR]). Results: 55 pts have received treatment. In the Ph 2 study, 21 pts received VM, 15 pts received VD. 35% of pts were included as 2nd line therapy, 65% in 3rd or later line of treatment. For pts receiving VD, safety was consistent with Ph 1B data. For pts receiving VM, median age was 67 yrs, ECOG 1 = 71.4%, Hgb < 10 gm/dL 13%, liver metastases 19%, ≥ 2 prior regimens 57%, (best response to prior therapy PD 31%). TEAEs occurring in ≥5% patients were asthenia (19%), diarrhea (9.5%), flushing 14%, chills (9.5%), hypotension (9.5%), decreased appetite (19%) and creatinine increased (9.5%). The majority of TEAS were grade 1 and 2. Only 1 patient on MF had a grade 3 TEAE and only 1 patient discontinued treatment due to an AE. The ORR have been seen in 7 pts to date including those receiving both VM and VD. Conclusions: Vofatamab both alone and combined with D in an every 3-week schedule are well tolerated with a low frequency of grade 3 TEAEs. Both VM and VD have demonstrated efficacy in terms of ORR, and mature results with PFS data will be presented. Clinical trial information: NCT02401542.

Abstract
Objective: To analyze the mortality and years of life lost (YLL) trends of cervical cancer in Tianjin, and provide references for the research and prevention programs of cervical cancer. Methods: Mortality rate, standard mortality rate, cumulative rate (0-74 years-old) and truncated rate (35-64 years-old) of cervical cancer from 1999 to 2015 were calculated. The annual percentage change of the mortality rate and YLL rate were analyzed by using Joinpoint regression analysis, and the trend in different age-groups were analyzed. Results: From 1999 to 2015, 1 741 cases died of cervical cancer in Tianjin, the average crude mortality rate was 2.15/100 000. The average age-standardized rate of (ASR) China and ASR world were 1.47/100 000 and 1.50/100 000 respectively. The average YLL was 3 347.97 person-years. Deaths occurred in those aged 0-34 years, 35-64 years and 65 years and over accounted for 3.10%, 57.84% and 39.06% of the total, respectively. The mortality rate of cervical cancer in urban area was higher than that in rural area, with a ratio of 1.37∶1 between urban area and rural area. The age-specific mortality rate of cervical cancer during 1999-2015 increased with age. Two peaks of mortality rate were observed in those aged 50 years and aged 75 years, during 2014-2015. From 1999 to 2011, the mortality rate of cervical cancer was stable (APC=-0.2%, P=0.80), but there was a rapid increase from 2011 to 2015 (APC=21.6%, P<0.01). But group aged 20-49 years, it showed an upward trend from 1999 to 2015 (APC=6.9%, P<0.01). For group aged 50-69 years, it showed a downward trend from 1999 to 2007 (APC=-9.2%, P<0.01), and an upward trend from 2007 to 2015 (APC=14.5%, P<0.01). For group aged 70 years and over, it showed a downward trend from 1999 to 2009 (APC=-10.2%, P<0.01), but the difference in the mortality were not significant from 2009 to 2015 (APC=7.8%, P=0.10). Since 2008, the YLL rate of cervical cancer in group aged 50-70 years had exceeded that in group aged >70 years and the gap gradually widened. Conclusions: There had been a rapid increase trend of cervical cancer mortality since 2011 in Tianjin. Women aged 50-70 years were the main group of life loss.

Abstract
BACKGROUND Studies from high-income countries report moderate-to-strong positive associations between alcohol use disorder (AUD) and other mental disorders, but there is little evidence about the comorbidity of AUD from low-and-middle-income countries. METHODS A sample of 74 752 adults from five provinces that account for >12% of China's adult population was screened using the General Health Questionnaire, and the Structured Clinical Interview for DSM-IV was administered by psychiatrists to a subsample of 9619 males. The associations between AUD and other mental disorders at each site and the characteristics of men with AUD with and without comorbid mental disorders were estimated using logistic regression and summarized across sites using meta-analysis. Generalized estimation equations estimated the associations between the clinical features of alcohol dependence and comorbidity. RESULTS Robust inverse associations were found between current AUD and any mood disorder (adjusted OR = 0.6, 95% CI = 0.4-0.8) and any anxiety disorder (OR = 0.5, 95% CI = 0.3-1.0). Compared with men without AUD, men with AUD without comorbid disorders were more likely to be middle-aged, to be currently married, and to have higher family incomes. Men with comorbid AUD and other disorders were more likely to have the clinical features of alcohol dependence than men with AUD without comorbid disorders. CONCLUSIONS Inverse associations between AUD and other mental disorders and the higher social status of men with AUD than men without AUD found in this large, representative sample of community-dwelling Chinese males highlight the importance of considering the local substance-use culture when designing clinical or preventive interventions for addictive conditions.

Abstract
Pigs have been recognised as a reservoir of livestock associated methicillin-resistant Staphylococcus aureus (LA-MRSA) in Europe, Asia and North America. However, little is known about the presence and distribution of MRSA in the Australian pig population and pig industry. This study describes the presence, distribution and molecular characteristics of the human adapted Australian CA-MRSA ST93 isolated from pigs, people, and the environment within a piggery. Isolates were subjected to antibiotic susceptibility testing, DNA microarray, whole genome sequencing, multi locus sequence typing, virulence and resistance gene characterization and phylogenetic analysis. MRSA were isolated from 60% (n = 52) of farm workers where 84% of isolates returned ST93 and the rest ST398. Of the thirty-one pig isolates tested further, an equal number of ST398 and ST93 (15 each) and one as ST30-V were identified. Four of six environmental isolates were identified as ST93 and two as ST398. This study has identified for the first time in Australia the occurrence of CA-MRSA ST93 and LA-MRSA ST398 amongst farm workers, pigs, and the farm environment. Comparative genome analysis indicates that ST398 is likely to have been introduced into Australia from Europe or North America. This study also reports the first linezolid resistant MRSA isolated in Australia.

Abstract
AIM To assess the extent of sigmoid sinus dehiscence (SSD) on high-resolution computed tomography venography (HRCTV) or high-resolution computed tomography (HRCT) images in pulsatile tinnitus (PT) and non-PT groups to determine whether there is an association between the extent of SSD and occurrence of PT. MATERIALS AND METHODS Twenty-eight SSD patients with ipsilateral PT and 28 age- and gender-matched SSD patients without PT who underwent HRCTV or HRCT were enrolled in this study and categorised into two groups: "PT group" and "non-PT group". The extent of SSD in each group was calculated and compared. RESULTS The largest transverse diameter and largest vertical diameter of SSD in the PT group were 6.21±1.7 and 6.15±2.19 mm, respectively. The largest transverse diameter and largest vertical diameter of SSD in the non-PT group were 3.06±1.38 and 2.51±1.03 mm, respectively. The extent of SSD was statistically different between the two groups (p<0.001; p<0.001). CONCLUSIONS As a cause of PT, SSD can also occur in individuals without PT symptoms. Preliminary findings suggest that there may be a potential correlation between the extent of SSD and an occurrence of PT.

Abstract
BACKGROUND Adipose tissue is an attractive source of mesenchymal stem cells (MSC) as it is largely dispensable and readily accessible through minimally invasive procedures such as liposuction. Until recently MSC could only be isolated in a process involving ex-vivo culture and their in-vivo identity, location and frequency remained elusive. We have documented that pericytes (CD45-, CD146+, and CD34-) and adventitial cells (CD45-, CD146-, CD34+) (collectively termed perivascular stem cells or PSC) represent native ancestors of the MSC, and can be prospectively purified using fluorescence activated cell sorting (FACS). In this study we describe an optimized protocol that aims to deliver pure, viable and consistent yields of PSC from adipose tissue. We analysed the frequency of PSC within adipose tissue, and the effect of patient and procedure based variables on this yield. METHODS Within this twin centre study we analysed the adipose tissue of n = 131 donors using flow cytometry to determine the frequency of PSC and correlate this with demographic and processing data such as age, sex, BMI and cold storage time of the tissue. RESULTS The mean number of stromal vascular fraction (SVF) cells from 100 ml of lipoaspirate was 34.4 million. Within the SVF, mean cell viability was 83 %, with 31.6 % of cells being haematopoietic (CD45+). Adventitial cells and pericytes represented 33.0 % and 8 % of SVF cells respectively. Therefore, a 200 ml lipoaspirate would theoretically yield 23.2 million viable prospectively purified PSC - sufficient for many reconstructive and regenerative applications. Minimal changes were observed in respect to age, sex and BMI suggesting universal potential application. CONCLUSIONS Adipose tissue contains two anatomically and phenotypically discreet populations of MSC precursors - adventitial cells and pericytes - together referred to as perivascular stem cells (PSC). More than 9 million PSC per 100 ml of lipoaspirate can be rapidly purified to homogeneity using flow cytometry in clinically relevant numbers potentially circumventing the need for purification and expansion by culture prior to clinical use. The number and viability of PSC are minimally affected by patient age, sex, BMI or the storage time of the tissue, but the quality and consistency of yield can be significantly influenced by procedure based variables.

Abstract
IntroductionVarious socio-demographic variables have been shown to influence attitudes towards seeking professional psychological help (ATSPPH), while negative ATSPPH can act as a barrier to mental healthcare, resulting in under-utilization of psychological services.Aims and objectivesTo explore the factor structure of the ATSPPH scale and determine whether any significant socio-demographic differences exist in relation to ATSPPH among a nationally representative sample.MethodsData was extracted from a population-based, cross-sectional survey conducted between March 2014 and March 2015 among Singapore Residents aged 18-65 years (n = 3006). Respondents completed the 10-item ATSPPH scale and also provided socio-demographic information. Exploratory factor analysis (EFA) was performed to establish the factor structure of the ATSPPH scale. Multivariable linear regression analyses were conducted to examine socio-demographic factors associated with ATSPPH.ResultsEFA revealed that the ATSPPH scale formed three distinct dimensions comprising “Openness to seeking professional help”, “Value in seeking professional help” and “Preference to cope on your own”. Higher “Openness to seeking professional help” scores were significantly associated with 18-34-year-olds and unmarried respondents, whilst Malay ethnicity and lower education were significantly associated with lower openness scores. Malays, Indians and lower education were significantly associated with lower “Value in seeking professional help” scores, whereas higher “Preference to cope on your own” scores were significantly associated with lower education.ConclusionPopulation subgroups including those with lower educational levels and different ethnic groups have more negative ATSPPH. Tailored, culturally appropriate educational interventions which reduce negative ATSPPH are needed, which effectively target these populations.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Metallic drug-eluting stents (DES) are the first choice for percutaneous coronary interventional treatment of coronary artery disease at present. Although they have overcome some disadvantages and limitations of plain balloon angioplasty and bare-metal stents, chronic local inflammatory reactions related to permanent polymer existence and poor vascular healing after first generation DES implantation may translate into the increased risk of late and very late stent thrombosis. There have been technological developments in stent design, materials and coatings, including more conformable platform designs, biocompatible or biodegradable polymers and improved kinetics of drug release. The newer generation DES have proven superior to previous DES technology in terms of both safety and efficacy. Accumulating evidence has suggested that DES with cobalt chromium stent platform, modified biodegradable polymer coatings, and rapamycin derivative drugs are associated with improved clinical outcomes. Currently, several new cobalt chromium biodegradable polymer sirolimus-eluting stents have been introduced to clinical practice. This review will describe basic concept and rationale behind the newer cobalt chromium biodegradable polymer sirolimus-eluting stents, systematically present the new clinical experiences with several representative devices.

Abstract
In this paper, we aimed to look for a potent long acting GLP-1 receptor agonist for diabetes treatment. In this work, we constructed the eukaryotic expression vector of GLP-1-Exendin-4/IgG4 (Fc)-pOptiVEC™-TOPO(®) and then transfected it into Chinese hamster ovary DG44 (CHO/DG44) cells using liposome method. Then the beta-cell line INS-1 cells were treated with purified GLP-1-Exendin-4/IgG4 (Fc) fusion protein (0.01, 0.1, 1.0 mM respectively) and randomly assigned to 2 groups, each group were then grown in KRB buffer in the presence of 2.8 mM or 16.8 mM glucose for 2 h separately. In addition, single dose of fusion protein was intraperitoneally injected into male CD1 mice for pharmacokinetic study. Besides, multiple low doses of streptozotozin (STZ) induced diabetes mice were used to evaluate the effect of fusion protein for anti-diabetes in male CD1 mice. GLP-1-Exendin-4/IgG4 (Fc) had stimulatory effect on insulin secretion glucose-dependently from INS-1 cells in a dose-dependent manner. Pharmacokinetic studies showed that the GLP-1 level increased significantly after injecting fusion protein and maintained a higher level for 200 h. Besides, multiple-low-dose STZ-induced diabetes mice which received intraperitoneal injections of fusion protein did not show sign of diabetes. Our results indicated that GLP-1-Exendin-4/IgG4 (Fc) fusion protein retained native GLP-1 activities and had effect on long-term glucose regulation. All the results suggest that this fusion protein may serve as a potent long acting GLP-1 receptor agonist.

Abstract
AIM We aimed to investigate the feasibility, initial safety and efficacy of coronary intervention using FIREHAWK®, a novel abluminal groove-filled biodegradable polymer sirolimus-eluting stent (SES), in patients with complex anatomical and clinical scenarios. METHODS A total of 57 patients (79 lesions) with complex anatomical and clinical scenarios implanted with the FIREHAWK® SES between March and November 2014 were studied. The primary endpoint was target lesion failure (TLF), a composite endpoint of cardiac death, target vessel-myocardial infarction (TV-MI), and ischemia-driven target lesion revascularization (iTLR). Optical coherence tomography and intravascular ultrasound was performed according to the discretion of operators. RESULTS 28.1% of patients presented acute myocardial infarction and all patients had at least one of the following anatomical and locational complexity: multi-vessel disease (64.9%), left main disease (24.6%), chronic total occlusion (17.5%), bifurcation (56.1%), and heavily calcified lesions (10.5%). One patients experienced coronary perforation during the procedure and resolved without any additional treatment. Device success was 100%, clinical success was 100%. There was 1 (1.8%) TLF occurred at follow-up of 150 ± 65 days. One patients had non-iTLR. Out of 2 non-Q-wave MI, 1 patient experienced TV-MI, but no death and stent thrombosis were reported. OCT and IVUS imaging showed a high rate of covered struts and low neointimal hyperplasia at follow-up. CONCLUSION The study showed the feasibility, initial safety and efficacy of coronary intervention using FIREHAWK® SES for treating patients with complex anatomical and clinical scenarios. The performance of the FIREHAWK® SES in complex patients justifies the conduct of a large, randomized trial.

Abstract
Dog bites are a significant pediatric public health challenge in rural China. This study evaluated the effect of various sources of dog-safety information on children's knowledge, attitudes, beliefs and practices with dogs. A total of 1925 children (grade 3-6) between 6 and 15 years old in four rural regions across China participated between May and September 2012. Results showed that teachers and especially parents were effective information sources for children to learn about dog safety. Learning from peers and children teaching themselves were ineffective education strategies. Multi-source learning (from both parents and teachers) did not differ from single-source learning (from parents but not teachers) but did exceed learning from teachers but not parents or no learning from adults. Older age was associated with greater safety knowledge but also riskier practices with dogs. Girls generally held more safety knowledge, less risky attitudes/beliefs and safer practices than boys. Neither age nor gender interacted with information sources on outcome measures. In conclusion, parents appear to play a major role in educating children in rural China on dog safety. Future dog safety interventions might focus on changing cognition and behavior as well as delivering basic knowledge to youth through teachers and especially parents.

Abstract
This open-label multicentre study evaluated ease of use, safety, and efficacy of a pen device for self-administration of recombinant follicle-stimulating hormone (rFSH) in 43 subjects undergoing ovulation induction. Follitropin beta was administered subcutaneously with the Follistim Pen within 3 days of onset of menses. A 75 IU starting dose could be increased by 25 or 50 IU on days 8 and 15 if no ovarian response was observed. Human chorionic gonadotrophin (HCG; 10,000 IU) was administered when one follicle > or =18 mm or two to three follicles > or =15 mm were observed. Subjects received standardized instruction for the pen device and subject comprehension was recorded as subjects practised and prepared injections. Ease of use was also evaluated by questionnaire. Forty-four subjects enrolled; 43 were treated with rFSH and 41 were treated with HCG. The comprehension questionnaire revealed that during the mock injection, 100% of subjects properly loaded the cartridge into the pen device, while 95% selected the correct dose and 100% self-injected the medication prescribed. During the second actual injection, 100% of subjects comprehended these pen-related steps. The ease-of-use questionnaire showed that 100% of the subjects rated the overall experience of self-administering with the pen as 'very good' to 'good'. Mean duration and total amount of follitropin beta were 11.4 +/- 4.2 days and 1070.3 +/- 580.3 IU respectively. Ovulation rate was 95%. Biochemical and ongoing pregnancy rates per attempt were 34.9 and 30.2% respectively. Three subjects experienced serious adverse events [asthma; ovarian hyperstimulation syndrome (OHSS) and pain; OHSS]. In conclusion, the pen device provides an easy, safe, and effective way for women to self-administer follitropin beta during ovarian stimulation.
