Objective To investigate the current status of tobacco control in public places in Jiading District, after the introduction of "Tobacco Control Regulation in Public Places of Shanghai" (amendment), providing basic data for further implementing regulations. Methods The method of field observation was adopted to conduct the monitoring in 14 representative public places, including site staff in 109 places in April and September. Results The display rate of tobacco control propaganda increased(χ²=10.588, P < 0.001), but the posting rate of pictures for smoking control warnings decreased(χ²=6.272, P=0.012);the differences between two monitoring results were both statistically significant; the smoking rate in the staff within the workplaces decreased to 5.17%(χ²=20.973, P < 0.05);the differences between two monitoring results were both statistically significant. Conclusion The situation of tobacco control in Jiading District public places is good, but in some places smoking control should be further strengthened, and the intensity of tobacco control in public places should be maintained.

OBJECTIVE: The primary objective of this study was to examine the validity and reliability of a semi-quantitative food frequency questionnaire (FFQ) among Chinese children aged 12-17 years. METHODS: A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls (24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children (N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients (ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs. RESULTS: For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman's correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from -0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification. CONCLUSION The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.

Objective To evaluate the performance of diluted thrombin time (dTT) assay for detecting Dabigatran levels and observe whether this assay may meet the requirements of clinical laboratory.Methods According to EP15-A2,EP6-A,EP7-A and C-24 documents of the Clinical and Laboratory Standards Institute (CLSI),the precision,trueness,analytical measurement range,carryover rate and anti-biological interference of dTT assay were evaluated and the stability of specimen for dTT assay was observed.Results Both the within-day and between-day coefficient of variation (CV) of dTT assay for detecting Dabigatran levels were consistent with manufacturer's stated CV.Compared with target values of Dabigatran,the relative bias of 3 levels of proficiency test materials from College of American Pathologists (CAP) were less than 10％.The results meet linear verification when Dabigatran concentration was between 30.92 and 249.13 ng/mL.The carryover rate was-0.84％.There was no interference for Dabigatran levels by dTT assay for detecting Dabigatran when Hb≤3 g/L,triglyceride≤873 mg/dL,heparin≤2.2 IU/mL and FDP≤29 mg/L.The results of stability showed that plasma specimens for dTT could not be stored at room temperature more than 4 hours,at 4 ℃ more than 4 days,at-20 ℃ exceed 1 month,while at-80℃ the plasma specimens could be stored at least 6 months for dTT assay.Conclusion The precision,trueness,analytical measurement range,carryover rate,anti-biological interference of dTT assay may meet the requirement of clinical laboratory.The stability of the specimen can fulfill the clinical requirements.

Background:The increasing prevalence of colorectal cancer (CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment.We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial burden of CRC patients in China.Methods:We conducted a multicenter,cross-sectional survey in 37 tertiary hospitals in 13 provinces across China between 2012 and 2014.Each enrolled patient was interviewed using a structured questionnaire.All expenditure data were inflated to the 2014 Chinese Yuan (CNY;1 CNY =0.163 USD).We quantified the overall expenditure and financial burden and by subgroup (hospital type,age at diagnosis,sex,education,occupation,insurance type,household income,clinical stage,pathologic type,and therapeutic regimen).We then performed generalized linear modeling to determine the factors associated with overall expenditure.Results:A total of 2356 patients with a mean age of 57.4 years were included,57.1％ of whom were men;13.9％ of patients had stage Ⅰ cancer;and the average previous-year household income was 54,525 CNY.The overall average direct expenditure per patient was estimated to be 67,408 CNY,and the expenditures for stage Ⅰ,Ⅱ,Ⅲll,and Ⅳ disease were 56,099 CNY,59,952 CNY,67,292 CNY,and 82,729 CNY,respectively.Non-medical expenditure accounted for 8.3％ of the overall expenditure.The 1-year out-of-pocket expenditure of a newly diagnosed patient was 32,649 CNY,which accounted for 59.9％ of their previous-year household income and caused 75.0％ of families to suffer an unmanageable financial burden.Univariate analysis showed that financial burden and overall expenditure differed in almost all subgroups (P ＜ 0.05),except for sex.Multivariate analysis showed that patients who were treated in specialized hospitals and those who were diagnosed with adenocarcinoma or diagnosed at a later stage were likely to spend more,whereas those with a lower household income and those who underwent surgery spent less (all P ＜ 0.05).Conclusions:For patients in China,direct expenditure for the diagnosis and treatment of CRC seemed catastrophic,and non-medical expenditure was non-ignorable.The financial burden varied among subgroups,especially among patients with different clinical stages of disease,which suggests that,in China,CRC screening might be cost-effective.

Background: Esophageal cancer is associated with substantial disease burden in China, and data on the economic burden are fundamental for setting priorities in cancer interventions. The medical expenditure for the diagnosis and treatment of esophageal cancer in China has not been fully quantified. This study aimed to examine the medical expenditure of Chinese patients with esophageal cancer and the associated trends. Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 37 hospitals in 13 provinces/municipalities across China as a part of the Cancer Screening Program of Urban China. For each esophageal cancer patient diagnosed between 2002 and 2011, clinical information and expense data were extracted by using structured questionnaires. All expense data were reported in Chinese Yuan (CNY; 1 CNY= 0.155 USD) based on the 2011 value and inflated using the year-specific health care consumer price index for China. Results: A total of 14,967 esophageal cancer patients were included in the analysis. It was estimated that the overall average expenditure per patient was 38,666 CNY, and an average annual increase of 6.27％ was observed from 2002 (25,111 CNY) to 2011 (46,124 CNY). The average expenditures were 34,460 CNY for stage Ⅰ, 39,302 CNY for stage Ⅱ, 40,353 CNY for stage Ⅲ, and 37,432 CNY for stage IV diseases (P < 0.01). The expenditure also differed by the therapy type, which was 38,492 CNY for surgery, 27,933 CNY for radiotherapy, and 27,805 CNY for chemotherapy (P < 0.05). Drugs contributed to 45.02％ of the overall expenditure. Conclusions: These conservative estimates suggested that medical expenditures for esophageal cancer in China substantially increased in the last 10 years, treatment for early-stage esophageal cancer costs less than that for advanced cases, and spending on drugs continued to account for a considerable proportion of the overall expenditure.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.

BACKGROUNDSunitinib has been proved an effective new option for treatment of metastatic renal cell carcinoma (mRCC). Analysis of clinical data of 22 patients, who were exposed to sunitinib for at least 1 year, was conducted to evaluate the long-term efficacy and safety of sunitinib for the treatment of mRCC.

METHODSA total of 54 patients with mRCC were treated with sunitinib malate, 50 mg/d orally, on a 4-weeks-on and 2-weeks-off dosing schedule in Peking University First Hospital. Treatment continued until disease progression, unacceptable adverse events (AEs), or death. Among them, 22 patients continued treatment for at least 1 year. The clinical data of these 22 patients were prospectively collected for analysis. AEs were assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events, Version 3.0. Tumor response was evaluated in accordance with the Response Evaluation Criteria in Solid Tumors.

RESULTSMedian progression-free survival was 19.5 months until last follow-up. The best efficacy results achieved were complete response, partial response, and stable disease for 2, 9, and 11 patients, respectively. Objective response rate was 50%. The most common AEs were hand-foot syndrome (95%) and hypertension (91%). Other common AEs were thyroid-stimulating hormone elevation (82%), platelet decrease (77%), and loss of appetite (77%). Only one patient withdrew from treatment for cardiac infarction. Another nine patients experienced dose modifications or short-term suspensions.

CONCLUSIONLong-term exposure to sunitinib malate showed encouraging efficacy in the treatment of mRCC. At the same time, the tolerability was good.
