Objective: To compare the application effect of the colonoscopy, fecal immunochemical test (FIT) and novel risk-adapted screening approach in colorectal cancer screening in Xuzhou population. Methods: From May 2018 to April 2019, 4 280 subjects aged 50-74 were recruited from Gulou district, Yunlong district and Quanshan district of Xuzhou. They were randomly assigned to the colonoscopy group (n=863), FIT group (n=1 723) and novel risk-adapted screening approach group (n=1 694) according to the ratio of 1∶2∶2. For the novel risk-adapted screening approach group, after the risk assessment, high-risk subjects were invited to undergo colonoscopy and low-risk subjects were invited to undergo FIT examination. All FIT positive subjects were invited to undergo colonoscopy. Colonoscopy participation rate [(the number of colonoscopies completed/the number of colonoscopies invited to participate)×100%], detection rate of colorectal lesions [(the number of diagnosed patients/the number of colonoscopies completed)×100%], colonoscopy resource load (the number of colonoscopies completed/the number of diagnosed advanced tumors) and FIT resource load in each group were calculated and compared. Results: The age of all subjects was (61±6) years old, including 1 816 males (42.43%). There was no statistically significant difference in the socio-demographic characteristics of the subjects in different screening groups. The colonoscopy participation rate was 22.60% (195/863) in the colonoscopy group, 57.04% (77/135) in the FIT group, and 33.94% (149/439) in the novel risk-adapted screening approach group, respectively. The colonoscopy participation rate was higher in the FIT group than in the colonoscopy group and the novel risk-adapted screening approach group (P<0.001). The colonoscopy participation rate of novel risk-adapted screening group was significantly higher than the colonoscopy group (P<0.001). The detection rates of advanced tumors were 6.67% (13/195), 9.09% (7/77) and 8.72% (13/149), respectively, and the difference was not statistically significant (P>0.05). The colonoscopy resource load (95%CI) was 15 (13-17) in the colonoscopy group, 11 (9-14) in the FIT group and 11 (10-13) in the novel risk-adapted screening approach group, respectively. Among them, the colonoscopy resource load of high-risk individuals in the novel risk-adapted screening approach group was 12 (9-15). FIT resource loads (95%CI) were 207 (196-218) and 88 (83-94) in the FIT group and the novel risk-adapted screening approach group. Conclusion: The combined application of risk-adapted screening approach and FIT may have a good application effect in colorectal cancer screening.

Pneumoconiosis, an interstitial lung disease that occurs from breathing in certain kinds of damaging dust particles, is a major occupational disease in China. Patients diagnosed with occupational pneumoconiosis can avail of free medical treatment, whereas patients without a diagnosis of occupational diseases cannot not claim free medical treatment in most provinces from the government before 2019. This study aimed to analyze the priority of medical facility selection and its influencing factors among patients with pneumoconiosis. A total of 1,037 patients with pneumoconiosis from nine provinces in China were investigated. The health service institutions most frequently selected by the patients were county-level hospitals (37.5%). The main reason for the choice was these hospitals' close distance to the patients' homes (47.3%). The factors for the choice of health care institutions were living in the eastern region (

Traumatic brain injury (TBI) would result in structural injury and/or physiological disruption of brain. Mild traumatic brain injury (mTBI) can result in vestibular dysfunctions, such as dizziness, vertigo and imbalance. Vestibular rehabilitation is effective on vestibular dysfunction after mTBI. This paper reviewed the possible mechanisms of vestibular dysfunction caused by mTBI, the common assessments of vestibular function and the new progress in vestibular rehabilitation.

Indigenous knowledge and traditional culture for sustainable use of native plants in Juenang cultural region of Rangtang county, Aba Zang and Qiang Prefecture of Sichuan province, have been characterized in this paper followed the principles and methods of ethnobotany. The results indicate that 38 species from 27 families(including 6 species of fungi) are ethnobotanically used commonly in this area. Of 38 species of the native plants, 13 species from 12 families are collected for eatables and vegetables, 12 families and 16 species of indigenous plants for medicinal and edible use, 4 species from 4 families for decoration, 4 species from 4 families used for building materials or firewood, and 1 species from 1 families used for religious folklore. Under the influence of Juenang culture and Tibetan culture, indigenous knowledge such as instinctive reverence and gratitude for nature, protection ecological environment and habitats, and moderate use of natural resources(especially wild bioresource), have been gotten passed on from generation to generation in Juenang culture region of Rangtang county, which is of great significance to the protection of local bioresources and environment, including ethnic medicinal plants, and also to provide practical guidance for biodiversity conservation and ecological restoration in those alpine ecological vulnerable areas.

Antifungal drug resistance is a significant clinical problem, and antifungal agents that can evade resistance are urgently needed. In infective niches, resistant organisms often co-existed with sensitive ones, or a subpopulation of antibiotic-susceptible organisms may evolve into resistant ones during antibiotic treatment and eventually dominate the whole population. In this study, we established a co-culture assay in which an azole-resistant Candida albicans strain was mixed with a susceptible strain labeled with green fluorescent protein to mimic in vivo conditions and screen for antifungal drugs. Fluconazole was used as a positive control to verify the validity of this co-culture assay. Five natural molecules exhibited antifungal activity against both susceptible and resistant C. albicans. Two of these compounds, retigeric acid B (RAB) and riccardin D (RD), preferentially inhibited C. albicans strains in which the efflux pump MDR1 was activated. This selectivity was attributed to greater intracellular accumulation of the drugs in the resistant strains. Changes in sterol and lipid compositions were observed in the resistant strains compared to the susceptible strain, and might increase cell permeability to RAB and RD. In addition, RAB and RD interfered with the sterol pathway, further aggregating the decrease in ergosterol in the sterol synthesis pathway in the MDR1-activated strains. Our findings here provide an alternative for combating resistant pathogenic fungi.

To provide evidence for Campylobacter jejuni (C.jejuni) vaccine research,the B cell epitope of AhpC protein were predicted,and the antigenicity was analyzed.AhpC was found locating in outer membrane of C.jejuni without transmem brane structure and no signal peptide by bioinformatics software TMHMM Server V2.0,SignalP 4.1.There were seven B-cell linear epitopes in AhpC predicted by IEDB.Then,the AhpC protein and chemically synthesized antigenic epitopes of C.jejuni were used as antigens,and the AhpC antibody of C.jejuni was used as the primary antibody,the antigens of predominant linear B cell epitopes were detected by ELISA and dot blot.Results showed that one epitope of B cell epitopes (AhpC4-16) was able to recognize the antibodies of C.jejuni AhpC and had strong antigenicity,indicating that could be used in the follow-up vaccine research.

OBJECTIVETo evaluate the efficacy and safety of tiotropium in treatment of severe persistent asthma.

METHODSReports of randomized controlled trials (RCTs) describing tiotropium for treatment of severe persistent asthma published from January 1946 to February 2015 were searched in Cochrane Library, ClinicalTrials.gov, PubMed, Ovid Medline, CNKI, and CSJD. The data of the included RCTs were extracted and the data quality was evaluated. Meta-analyses were performed with Revman 5.3 software.

RESULTSFive RCTs including 1433 patients were analyzed. Meta-analysis of the data showed that compared with the placebo group, tiotropium treatment significantly improved the patients' peak forced expiratory volume in one second (FEV1) [weighted mean difference (WMD): 0.13 L, 95% confidence interval (CI): 0.10-0.16 L, P<0.00001], trough FEV1 (WMD: 0.09 L, 95%CI: 0.06-0.12 L, P<0.00001), peak forced vital capacity (FVC) (WMD: 0.10 L, 95%CI: 0.06-0.14 L, P<0.00001), trough FVC (WMD: 0.12 L, 95%CI: 0.08-0.17 L, P<0.00001), morning peak expiratory flow (PEF) (WMD: 9.21 L/min, 95%CI: 4.2-14.23 L/min, P=0.0003), evening PEF (WMD: 22.06 L/min, 95%CI 13.05-31.08 L/min, P<0.00001). The scores of asthma control questionnaire (ACQ) (WMD: 0.01, 95% CI: -0.07-0.09, P=0.86) or asthma quality of life questionnaire (AQLQ)(WMD: 0.06, 95% CI:-0.18-0.06, P=0.33) were not affected by tiotropium. No significant difference with adverse events between tiotropium group and placebo group were reported in these included studies (P>0.05).

CONCLUSIONSTiotropium for severe persistent asthma treatment can improve FEV1, FVC, and PEF but may not improve the quality of life of the patients. Tiotropium is well tolerated and can be an add-on therapy for severe persistent asthma.

Objective To investigate the effects of asbestos exposure on plasma miRNA expression.Methods Plasma samples were collected from control group and asbestos -exposed group (time of exposure >10 years)and three samples from each group were selected to detect differentially expressed miRNA using LC Sciences miRNA Microarray -Single.The target genes of differential miRNA were predicted by three kinds of online software,Target Scan,miRanda and PicTar.GO term enrichment and KEGG pathways were analyzed.Results The results of microarray indicated that there were 40 differential miRNA expression between exposed and control groups(P <0.05),and the signal value of 9 differential miRNA exceeded 500.After analyzing signal pathways of target genes of 5 miRNA,of which the signal values were over 500,these target genes were found mainly involved in pathways associated with cancer and metabolism,including potential function targets of FAS,TP53 and FGFR3.Conclusion Asbestos exposure can result in differentially expressed miRNA in the plasma from workers occupationally exposed to asbestos and the target genes of these miRNA may play important roles in the pathways of cancer.However,the mechanism of these miRNA in asbestos -related diseases needs to be further studied in the future.

OBJECTIVETo summarize the clinical features of diffuse panbronchiolitis (DPB).

METHODWe retrospectively analyzed the clinical data of 35 patients who had been admitted to Peking Union Medical College Hospital from December 1996 to July 2014 due to DPB,which was confirmed basing on the diagnostic criteria proposed in 1998 by a working group of the Ministry of Health and Welfare of Japan or histopathological examination.

RESULTSThe average age of these 35 patients (20 men and 15 women,with a sex ratio of 1.33 to 1) was (42.2<15.6) years,mainly distributed in the 40-49 age group. The average clinical history was (8.4<8.5) years. The main symptoms and signs of DPB included chronic cough (n=35,100%),copious purulent sputum production (n=31,88.6%),exertional dyspnoea (n=24,68.6%),end-inspiratory crackles (n=28,80.0%). Also,26 patients (74.3%) had a history of sinusitis. Cold agglutination test in 15 out of 15 patients were negative. Pseudomonas aeruginosa and Haemophilus influenza were isolated from 22 patients (73.3%,22/30),and 26 patients (83.9%,26/31) had hypoxemia. The mean values of forced expiratory volume in the first second/forced vital capacity,residua volume/total lung volume,maximum forced expiratory volume of 50% lung volume,and maximum forced expiratory volume of 25% lung volume were 60.5%,53.8%,25.9%,and 31.2%,respectively. The most common CT findings from this cohort of patients were bronchiectasis and bronchiolitis,with nodular shadows distributed in a centrilobular pattern. Finally,29 patients were misdiagnosed as other conditions such as pulmonary infection and bronchiectasis.

CONCLUSIONSDPB in Chinese populations have different presentations compared to that Japanese populations:for instance,the serum cold agglutination test always shows negative results,which is often inconsistent with the pathogens in sputum. DPB usually is misdiagnosed. Clinicians should take DPB into consideration when patients had pulmonary infection and sinusitis.
