Background and Objective:Lung adenocarcinoma is,at present,the most common malignancy in the world and its overall 5-year survival rate is disappointing.Because most of the patients are diagnosed at advanced stage,early diagnosis may improve the prognosis of patients with lung adenocarcinoma.Surface-Enhanced Laser Desorption and Ionization Mass Spectrometry(SELDI) is one of the currently used techniques to identify biomarkers for cancers.This study explored the application of serum SELDI proteomic patterns to distinguish lung adenocarcinoma patients from healthy individuals.Methods:Serum samples from 71 lung adenocarcinoma patients,71 healthy volunteers with matched gender,age and history of smoking were analyzed using WCX2 ProteinChip to select potential biomarkers.Proteomic spectra were generated by mass spectrometry.Results:Five highly expressed potential biomarkers were identified with the relative molecular weights of 4047.79?1.60,4203.99?1.91,4959.81?2.13,5329.30?2.55 and 7760.12?4.11.The sensitivity for diagnosing lung adenocarcinoma was 90.14%,78.87%,50.70%,57.75%,73.24%;and specificity was 97.18%,92.96%,70.42%,76.06%,94.37%,when the critical point was made 1.5.Conclusions:SELDI-TOF-MS ProteinChip technology is a quick,easy,convenient,and highoutput analyzing method that it is capable of selecting several relatively specific,potential biomarkers from the serum of lung adenocarcinoma patients and may have clinic value.

Objective To evaluate the knowledge,attitude and practice(KAP)related with AIDS of local floating population.Methods A total of 1 942 floating persons were sampled by multistage cluster sampling and interviewed with questionnaire in the agricultural markets,construction sites,and their habitats within 3 communities in Hongkou District.Results 82.9% of the interviewees were 20 ～49 years old.The average score was 34.77 ±3.52 (maximum score is 44)for knowledge,12.11 ±2.32(maximum score is 19)for attitude,5.50 ±0.95(maximum score is 7)for practice,respectively.The scores increased with educational level significantly.The scores of knowledge were 33.26 ±3.54,34.63 ±3.23,36.56 ±3.39 among the subjects with educational levels of primary school and below,junior high school,senior high school and above.The scores of attitude were 13.77 ±2.27,14.79 ±2.39,15.62 ±2.38,respectively.And the score of practice was 5.40 ±0.90,5.51 ±0.93,5.58 ±1.03,respectively.Conclusion In the present,the KAP relating AIDS of local floating population is poor in Hongkou District.A variety of intervention methods and operational patterns should be developed for the floating population with different educational levels and jobs.

Objective: To analyze satisfaction with follow-up management of HIV/AIDS cases conducted by Community Health Service Center (CHS) and related factors in Hongkou district, Shanghai. Methods: Out of 302 HIV/AIDS cases followed up by CHS in Hongkou district from 2012 to 2016, 263 HIV/AIDS cases were recruited to participate in a cross-sectional study assessed by self-designed questionnaire-based interview during October 1, 2016 and October 20, 2016, with efficiency of 87.1%. Information of basic characteristics including sociodemographic, routes of infection, CD4⁺T cell counts, diagnose of AIDS and status of receiving ART were collected, as well as satisfaction with follow-up management conducted by CHS including service professionalism, service attitude, service environment, referral service, privacy protection, health education, psychological support, and care and assistance. Factors related to satisfaction were analyzed using multiple binary logistic regression. Results: Among 263 HIV/AIDS cases, the average age was 42.0±13.5, 93.2% (245 cases) were male and the proportion of overall satisfaction was 72.2% (190 cases). Out of 8 items of satisfaction, service attitude and health education got the highest score with a total number of 235 (89.4%) answering "very satisfied" or "satisfied" , while care and assistance got the lowest score with a total number of 69 (26.2%) answering "dissatisfied" or "very dissatisfied" . Compared to HIV/AIDS local residents and followed up by CHS <12 months, those who were non-local residents and followed up by CHS ≥12 months were more likely to be satisfied, the OR (95%CI) were 2.66 (1.30-5.44) and 2.52 (1.01-6.29), respectively. Compared to HIV/AIDS ≤30 years old and receiving ART, those who were 31-50 years or >50 years old and not receiving ART were less likely to be satisfied, the OR (95%CI) were 0.36 (0.15-0.89), 0.32 (0.10-0.97) and 0.11 (0.01-0.90), respectively. Conclusion Satisfaction with follow-up management conducted by CHS in Hongkou district is relatively high. Age, residence, status of receiving ART and cumulative time of following up by CHS are significantly associated with satisfaction, suggesting that CHS should improve their professional abilities during follow-up management, as well as be more targeted and focus on different aspects.
