Abstract
High-risk human papillomavirus (HPV)-related cancers consist of cervical cancer, anal cancer, penile cancer, vulvar cancer, vaginal cancer, and head and neck cancer (HNC). Of these, the disease burden of HNC is second only to cervical cancer. HNC mostly originates from malignant lesions of squamous epithelial cells and mainly includes oral cavity cancer, pharyngeal cancer (including nasopharyngeal cancer, oropharyngeal cancer, and hypopharyngeal cancer), and laryngeal cancer. Tobacco use, alcohol abuse, and HPV infection are three primary risk factors. Recently, there is an upward trend of HNC incidence globally, especially in high-income countries. In China, the disease burden and trends of HPV-related HNC are still not clear. A few small sample size and single-center studies suggest a high HPV prevalence and increasing trend in HNC. Methodological differences in HPV testing and regional variabilities still exist among these studies. Among the anatomic sites, oropharyngeal cancer has been shown to be caused by HPV infection, but the association of HPV with other sites is still under debate. In addition, there is a paucity of relevant studies. Here, this review narrates the association between HPV infection and HNC, compares the differences between global and Chinese studies, and then explores the importance of HPV infection in various anatomical sites. The main objective is to highlight the research on HPV-related HNC and promote relevant prevention and treatment programs.

Abstract
Objective: To investigate the clinical features, morphological characteristics, immunophenotype, and differential diagnosis of goblet cell adenocarcinoma (GCA) in the digestive system. Methods: The clinicopathological data, morphological characteristics, immunophenotypes of 22 cases of GCA in the digestive system diagnosed from January 2010 to January 2021 were collected. Meanwhile, 25 cases of neuroendocrine neoplasm (NEN) and 24 cases of adenocarcinoma were used as controls. Relevant literature was also reviewed. Results: There were 16 males and 6 females, aged from 36 to 79 years with an average of 56 years. The anatomical sites of the 22 GCA were mostly appendix (17 cases) and occasionally extra-appendix (5 cases), including 3 cases in stomach, 1 case in duodenum and 1 case in anal. All 17 cases of appendiceal GCA were pure GCA. Among the 5 cases of extra-appendiceal GCA, One case of gastric GCA was pure, two cases of gastric GCA with NEN or adenocarcinoma, duodenal GCA with NEN and adenocarcinoma, anal GCA with NEN.Low-grade GCAs were composed of goblet, Paneth and neuroendocrine cells, which were arranged in intestinal crypt tubular or cluster structures and distributed in the wall of digestive system. The tubular and cluster structures lacked adhesion. Goblet cells were columnar, located in the base, with clear cytoplasm, small nuclei, inconspicuous atypia, and uncommon mitoses. Extracellular mucus and signet-ring cells with nuclear variations could be seen in some cases. Nerve fiber bundle invasion and tumor thrombus in vessels were often present. High-grade GCAs lacked tubular and cluster structures, and their histological structures were more complex. Tumor cells expressed mixed neuroendocrine and glandular epithelial markers. Similar to the expression patterns of synaptophysin and chromogranin A, CD200 and INSM1 were also dot-like or patch-positive in GCA. Conclusions: GCA is an infrequent tumor of the digestive system and shows the bi-directional differentiation characteristics of neuroendocrine and glandular epithelium. Accurate diagnosis and staging are related to its prognosis.

Abstract
The pollution level, emission characteristics, and emission factors of PCDD/Fs from a number of steel plants were investigated in a particular province of China. The results showed that the concentration of PCDD/Fs was at a low level and decreased by 1-2 orders of magnitude compared with that in 2005-2019. In detail, the concentrations of PCDD/Fs ranged from 0.003-0.557 ng·m-3(I-TEQ), and the mean value was 0.165 ng·m-3 for the sintering process. Moreover, the concentrations of PCDD/Fs ranged from 0.006 to 0.057 ng·m-3, and the mean value was 0.025 ng·m-3 for the electric furnace process. In addition, the concentration of PCDD/Fs in the iron and steel industry from 2005 to 2020 increased first and then decreased, especially after the implementation of the new emission standard and the ultra-low emission control of conventional pollutants such as smoke, showing a significant decline. The results of fingerprint analysis showed that 2,3,7,8-TCDF was the largest congener contributing to the mass concentration, and lower chlorinated PCDFs were increased. This result differed from those of previous studies in which highly chlorinated PCDFs and PCDDs dominated, indicating that the generation source of PCDD/Fs had changed. The congener and isomer profiles of PCDD/Fs in flue gas from the sintering process were similar to those in the flue gas from the electric furnace process. Additionally, showing the characteristics of the typical high-temperature thermal process, the de novo synthesis may be the dominant mechanism of formation of PCDD/Fs in the sintering process and electric furnace process. The emission factor was 0.003-0.5 μg·t-1 (I-TEQ), and the average emission factor was (0.18±0.22) μg·t-1 for the sintering process. The emission factor was 0.04-0.5 μg·t-1, and the average emission factor was (0.27±0.23) μg·t-1 for the electric furnace process. These values were far lower than those of the standard toolkit for identification and quantification of dioxin and furan emissions released by UNEP in 2013 and the emission factors in the dioxin emission inventory of China in 2004. It is suggested that the emission factors of PCDD/Fs in the iron and steel industry of China should be studied and updated.

Abstract
Objective: To estimate stomach cancer incidence and mortality in Henan, 2016 and analyze the trend of stomach cancer incidence and mortality from 2010 to 2016. Methods: Stomach cancer related data in 2016 was extracted from Henan cancer registration and follow-up system. All data were qualified in validity, reliability and completeness according to the Guideline on Cancer Registration in China and International Agency for Research on Cancer (IARC/IACR). The incidence and mortality of stomach cancer were estimated by areas, gender and age based on the quality data and the registered population data of Henan province in 2016. The epidemic trend of stomach cancer was also been evaluated based on the age-standardized incidence and mortality by Chinese population (ASR China) from 2010 to 2016. Results: In 2016, the estimated incident cases of stomach cancer were 44 311. The incidence was 41.07/100 000, ASR China was 30.17/100 000, ASR by world population (ASR world) was 30.36/100 000, and the cumulative incidence rate was 3.84%. The incidences of male and female were 55.65/100 000 and 25.35/100 000, respectively. Meanwhile, 32 927 people died of stomach cancer in Henan. The mortality was 30.52/100 000, ASR China was 21.45/100 000, ASR world was 21.54/100 000, and the cumulative mortality was 2.53%. From 2010 to 2016, both the ASR China for incidence and mortality of stomach cancer in Henan showed a steady downward trend. In rural, the ASR China for incidence and mortality decreased rapidly, while the stable trend was observed in urban. Nevertheless, the incidence and mortality of stomach cancer in rural were still higher than those in urban. Conclusions: The incidence and mortality of stomach cancer in Henan province showed steadily declining trend from 2010 to 2016, and the geographical distribution difference between rural and urban areas was gradually narrowing. However, the disease burden was still high in 2016.

Abstract
Objective: To estimate the incidence and mortality of esophageal cancer in 2016 and their changing trend during 2010-2016 according to the cancer registration data in Henan province. Methods: The data quality including completeness, validity, and reliability of local registries which submitted the cancer registration data of 2016 were assessed according to the criteria of Guideline on Cancer Registration in China and IARC/IACR. Esophageal cancer cases (ICD10: C15) were extracted from the database, and the incidence and mortality stratified by gender, age, and areas (urban/rural) were calculated, the incidence and mortality of provincial cancer were estimated combined with provincial population data. China's 2000 census population and Segi's population were used to calculate the age-standardized rate. Joinpoint model was used to estimate the changing trend of age standardized incidence and mortality along with the calendar year. Results: Approximately 40.10 thousand new esophageal cancer cases were diagnosed in Henan in 2016, accounting for 13.46% of all new cancer cases, and it ranked the third among cancer of all sites. The crude incidence of esophageal cancer was 37.21/100 000 with an age-standardized incidence rate by China standard population (ASIRC) of 26.74/100 000 and an age-standardized incidence rate by world standard population (ASIRW) of 27.12/100 000. The incidence of esophageal cancer in males was higher than that in females, with the ASIRC of 34.53/100 000 and 19.19/100 000, respectively. It was higher in rural areas than that in urban areas, with the ASIRC of 28.13/100 000 and 20.90/100 000, respectively. About 29.30 thousand deaths of esophageal cancer in Henan in 2016, accounting for 15.61% of all cancer deaths in Henan, which ranked the third among cancer of all sites. The crude mortality rate was 27.14/100 000 with an age-standardized mortality rate by China standard population (ASMRC) of 18.74/100 000 and an age-standardized mortality rate by world standard population (ASMRW) of 18.78/100 000. The mortality in males was higher than that in females, with the ASMRC of 24.78/100 000 and 13.12/100 000, respectively. It was also higher in rural areas than that in urban areas, with the ASMRC of 19.48/100 000 and 15.73/100 000, respectively. The ASIRC and ASMRC were declining with annual percent change (APC) of 3.12% (APC=-3.12%; 95%CI: -5.30%, -0.90%; P=0.015) and 2.47% (APC=-2.47%; 95%CI: -4.70%, -0.20%; P=0.039) during 2010-2016. However, the significant declining trend was only observed in rural areas in Henan, and the changing trend was same between males and females. Conclusions: The incidence and mortality of esophageal cancer are declining since 2010, however, the disease burden remains large in Henan. Therefore, comprehensive prevention and control efforts should be strengthened according to its epidemic characteristics and risk factors.

Abstract
Objective: To systematically evaluate the methodological quality of screening guidelines for upper gastrointestinal cancer (including esophageal cancer and gastric cancer) both at home and abroad, and provide reference for the update of upper gastrointestinal cancer screening guidelines in China. Methods: Original articles and grey literature published as of 31th Aug 2020 were retrieved using Chinese databases (CNKI, Wanfang, China Biomedical Literature Database and China Guideline Clearinghouse), PubMed, The Cochrane Library and Embase, as well as those from International Agency for Research on Cancer and the International Guide Collaboration Network. The inclusion criteria were being independent guidelines/recommendation documents for upper gastrointestinal cancer screening and meeting the definition of the institute of Medicine, USA. The exclusion criteria were being guideline abstracts, interpretation and evaluation literature, duplicate publications, updated original guidelines, and clinical treatment or practice guidelines for esophageal or gastric cancer. Appraisal of Guidelines for Research and Evaluation (AGREE Ⅱ) and Reporting Items for Practice Guidelines in Healthcare (RIGHT) were used to compare and evaluate the quality and reporting standard of esophageal or gastric cancer screening guidelines. Results: A total of 6 esophageal cancer screening guidelines and 5 gastric cancer screening guidelines were included. The results of the AGREE Ⅱ quality evaluation showed that the overall quality of eleven guidelines varied, including two guidelines recommended for "A", one for "B", five for "C" and three for "D". The guidelines had higher scores in the areas of scope and purpose, and clarity. The esophageal cancer screening guidelines had different scores in the areas of rigor and independence. The gastric cancer screening guidelines generally had low scores in the areas of participants and application. The RIGHT evaluation results showed that the quality of eleven guidelines should be improved. The six items with poor report quality were background, evidence, recommendations, review and quality assurance, funding and conflict of interest statement and management and others. Conclusion: The quality of the included upper gastrointestinal cancer screening guidelines is general, and the standardization needs to be strengthened.

Abstract
Objective: To evaluate the compliance rate and its impact factors of liver cancer screening for high-risk groups in urban areas of Henan Province from 2013 to 2019. Methods: Residents of 40-74 years old in 8 cities of Henan province were selected to investigate the risk factors and liver cancer risk assessment. Subjects with high risk of liver cancer received AFP combined ultrasonography for screening. Chi-square tests were used to compare the differences in liver cancer screening participation rates between groups. Multivariate logistic regression models were applied to explore the potential factors correlating to the compliance of liver cancer screening. Results: Overall, 3 6781 participants who met the inclusion criteria were included in this analysis, and 17 241 of them took the following liver cancer screening, yielding a participation rate of 46.87%. The participation rate varied greatly across cities, ranging from 62.50% to 38.59%. Moreover, the participation rate varied greatly across periods, ranging from 52.77% in 2014-2015 to 38.14% in 2013-2014. The multivariate Logistic regression analyses showed that: female, older, high education degree, cigarette and alcohol intake, infrequent physical exercise, chronic hepatitis B, chronic hepatitis C, fatty liver, gallstones and a family history of liver cancer were inclined to accept liver cancer screening (P<0.05). Conclusions: The overall participation rate of liver cancer screening among high-risk population is less than 50% in urban areas of Henan Province. Implement of effective interventions targeting the specific high-risk populations might improve the overall compliance rate of liver cancer screening in the future.

Abstract
Objective: To analyze the effects of esophageal cancer screening in Henan rural areas with cancer screening program from 2014 to 2018. Methods: From July 2014 to June 2019, according to the National Early Diagnosis and Treatment of Upper Gastrointestinal Cancer in Rural Areas Project, cluster sampling method was adopted in 16 counties/county-level cities in rural areas with high incidence of esophageal cancer in Henan province. Endoscopic iodine staining and indicative biopsy were used to screen esophageal cancer. The patients with mild and moderate dysplasia confirmed in screening were followed up. The distribution of esophageal diseases in the screening population was calculated, and Chi-square test was used to compare the differences of detection rate and early diagnosis rate between the primary screening population and the follow-up population. Results: The age of 116 630 primary screening population was (54.29±7.70) years old, and the proportion of males was 41.2% (48 108). In the primary screening population, patients with normal esophagus, mild to moderate dysplasia, severe dysplasia and above accounted for 92.91% (108 363), 6.03% (7 035) and 1.06% (1 232), respectively. The detection rate of esophageal cancer was 1.06% (1 232/116 630), and the rate of early diagnosis was 85.80% (1 057). Among the follow-up population of 6 154 people, those with normal esophagus, mild to moderate dysplasia, severe dysplasia and above diseases accounted for 63.45% (3 905), 33.13% (1 519) and 3.41% (210), respectively. The detection rate of esophageal cancer was 3.41% (210/6 154), and the rate of early diagnosis was 91.90% (1 939). Compared with the primary screening population, the risk of esophageal cancer was higher in the overall follow-up population, people either with mild or with moderate dysplasia diagnosed in primary screening, with OR values (95%CI) of 3.23 (2.78, 3.75), 1.85 (1.49, 2.29) and 8.13 (6.69, 9.88), respectively. Conclusion: From 2014 to 2018, in the early diagnosis and early treatment of upper digestive tract cancer project in rural areas of Henan Province, the detection rate of the follow-up population is significantly higher than that of the primary screening population. Improving follow-up rate and paying more attention to the screening of people who need follow-up could further improve the screening effect.

Abstract
Objective: To estimate cancer incidence and mortality of kidney and unspecified urinary organs in China using cancer registry data in 2015. Methods: The cancer registry data from 501 local cancer registries in China were collected, checked and assessed based on the criteria of data quality control of the National Central Cancer Registry of China (NCCRC), and data from 368 registries were qualified for the analysis. Cancer incidence and mortality rates of kidney and unspecified urinary organs stratified by geographical location (eastern, middle, western areas), gender, age groups were calculated. Population data of 2015 was used to estimate the cancer cases and deaths of kidney and unspecified urinary organs in China. Chinese standard population in 2000 and Segi's world population were used for the calculation of age-standardized incidence and mortality rates. Results: A total of 74.2 thousand new cancer cases of kidney and unspecified urinary organs were diagnosed in 2015, 46.9 thousand of them were male, while 27.3 thousand were female, with a crude incidence rate of 5.40/10(5). The age-standardized incidence rates by Chinese (ASIRC) and world standard population (ASIRW) were 3.57/10(5) and 3.56/10(5), respectively. A total of 53.4 thousand and 20.8 thousand new cases were diagnosed in urban and rural area, with incidence rates of 6.93/10(5) and 3.45/10(5), respectively. The ASIRC of urban area was higher than that of rural area. There were 39.2 thousand, 20.6 thousand, and 14.4 thousand new cases diagnosed in eastern, middle, and western areas of China, respectively. The crude incidence rates were 7.60/10(5), 4.47/10(5), and 3.63/10(5), respectively, with a descend ASIRC of each area. A total of 27.1 thousand death cases reported, of them 16.9 thousand were male, while 10.2 thousand were female, with a crude mortality rate of 1.97/10(5), both of the ASIRC and ASMRW were 1.21/10(5). The deaths of urban and rural area were 19.5 thousand and 7.6 thousand cases, with the crude mortality rates of 2.53/10(5) and 1.26/10(5), respectively. The ASIRC of urban area was higher than that of rural area. There were 13.4 thousand, 8.4 thousand, and 5.1 thousand death cases reported in eastern, middle, and western areas, respectively, the crude mortality rates were 2.61/10(5), 1.83/10(5) and 1.30/10(5), respectively, with a descend ASIRC of each area. Conclusion: The disease burden of kidney cancer differs between urban area and rural area, and differs among eastern, middle, and western areas of China, therefore, different prevent and treatment strategies should be taken in different areas of China.

Abstract
Objective: To evaluate the compliance of low-dose computed tomography (LDCT) screening for high-risk groups of lung cancer and influencing factors in urban area of Henan province during 2013-2017. Methods: Cluster sampling method was used to select the residents of 40-74 years old in Henan for cancer risk factor investigation and lung cancer risk assessment. Subjects with high risk of lung cancer received LDCT screening. The differences of LDCT receiving rates between groups were compared with χ(2) tests, and the time trend of rates were tested with the Cochran- Armitage trend test. The potential factors correlating to the compliance of LDCT screening were identified with multivariate logistic regression models. Results: Overall, 35 672 participants who met the inclusion criteria were included in this analysis, and 13 383 of them received LDCT screening, the receiving rate was 37.52%. The receiving rate varied greatly across cities, ranging from 38.47% to 26.73% (P<0.05). Moreover, the receiving rate varied greatly across periods, ranging from 29.22% during 2013-2014 to 43.30% during 2014-2015, and the receiving rate increases gradually as the screening year increases (P<0.001). The multivariate logistic regression analyses showed that: being female, age 45-69 years, with education level of junior high school/high school, previous smoking, drinking or previous drinking, infrequent physical exercise, history of tuberculosis, history of chronic bronchitis, history of emphysema, history of asthma bronchiectasis and family history of lung cancer were positive factors for receiving LDCT screening (All P<0.05). Conclusions: The overall compliance of LDCT screening in high-risk population of lung cancer was still not high in urban area of Henan. Implementation of effective interventions targeting the specific high-risk populations might improve the overall compliance of LDCT screening in the future.

Abstract
Objective: To study the compliance of endoscopic screening for high-risk population of upper gastrointestinal cancer and relevant factors in urban areas of Henan Province, 2013-2017. Methods: The study participants were from the Cancer Screening Program in Urban Henan Province, China. From October 2013 to October 2017, 43 423 residents, who were evaluated as high-risk population for upper gastrointestinal cancer, were recruited from Zhengzhou, Zhumadian and Anyang. The cancer risk assessment questionnaire was used to collect basic demographic characteristics, dietary habits, living environment and habits, psychology and emotions, disease history and family history of cancer, and women's physiological and reproductive history. The data of endoscopic screening was obtained from hospitals participating in the Cancer Screening Program. Multivariate logistic regression model was applied to explore potential factors related to the compliance of endoscopic screening. Results: The age of study participants was(55.49±8.15) years old, and 44.00% (19 105) were male. About 18.41% of study subjects (7 996) took the endoscopic screening. The multivariate logistic regression analysis showed that females, individuals aged 45-64 years old, with junior high school education or above, unmarried/divorced/widowed, previous smoking, alcohol drinking, infrequent physical exercise, history of reflux esophagitis, history of superficial gastritis, history of gastric ulcer, history of duodenal ulcer, history of gastric polyps and family history of upper gastrointestinal cancer were more likely to accept endoscopic screening. Conclusion: The overall participation rate of endoscopic screening among high-risk population of upper gastrointestinal cancer was still low in urban areas of Henan Province. Gender, age, education, marital status, smoking, alcohol consumption, physical activity, history of upper gastrointestinal disease and family history of upper gastroin testinal cancer were associated with the compliance of endoscopic screening.

Abstract
Objective: To evaluate the performance of High-risk HPV typing detection in cervical cancer screening. Methods: A total of 3 231 women were recruited as the subjects of cervical cancer screening from Jiyuan city of Henan provinces from June to July 2017. All women underwent HPV DNA test. The women with cytological examination ≥ASCUS or cytological examination negative and HPV 16/18 positive underwent colposcopy biopsy and pathological examination. Pathological diagnosis was used as the gold standard. Sensitivity, specificity, positive predictive value (PPV), negative predictive value(NPV) as well as corresponding 95% confidence interval (CI) of HR-HPV and HPV 16/18 were calculated. Results: The mean age of 3 231 subjects selected in this study was 46.84±10.00 (21-64) years old. 524 subjects had the positive results of HR-HPV, including 91 of HPV16 and 15 of HPV18. Pathological test result CIN2+ was the gold standard. The sensitivity and specificity of HR-HPV for cervical precancer lesions screening were 93.75 (95%CI: 79.85-98.27) and 84.56% (95%CI: 83.26-85.77), respectively. To compared with HR-HPV, HPV16/18 had low sensitivity (65.63%, 95%CI: 48.31-79.59)and higher specificity (97.44%, 95%CI: 96.83-97.93). After age stratification by age 30 and 45, the sensitivity of HPV 16/18 was same with HR-HPV (100%, 95%CI: 34.24-100.00), the specificity of HPV 16/18 was higher than HR-HPV (98.71%, 95%CI: 96.27-99.56 vs 84.48%, 95%CI: 79.27-88.58) in<30 age group.The sensitivity of HR-HPVin 30-45 and ≥45 age group were higher than HPV16/18 (85.71%, 95%CI: 48.69-97.43 vs 71.43%, 95%CI: 35.89-91.78, 95.65%, 95%CI: 79.01-99.23 vs 60.87%, 95%CI: 40.79-77.84), but the specificity werelower than HPV16/18 (86.89%, 95%CI: 84.58-88.90 vs 98.51%, 95%CI: 97.51-99.11、83.49%, 95%CI: 81.81-85.04 vs 96.80%, 95%CI: 95.94-97.48). Conclusions: HR-HPV detection has relatively high sensitivity and specificity in cervical cancer screening. For >30 years old women, HR-HPV is more recommended in cervical cancer screening. Therefore, HR-HPV detection is an effective method for cervical cancer screening.

Abstract
Cervical cancer is the fourth common cancer in women globally, with the number of new cases accounted for 18.6% among all the cancer patients, in China. It is well known that the situation of prevention and control programs are quite challenging. Based on the efforts being made in the last 20 years, the etiology and carcinogenesis on cervical cancer had been clearly understood. Breakthroughs had been achieved in the development of prophylactic human papillomovirus vaccine and the technology of in screening. Various screening strategies are already available in areas with different economic status. Nevertheless, the capacity of health care services at the primary care clinics needs to be improved to narrow the gap between the reality and the demands.

Abstract
Objective: This study aimed to evaluate the clinical performance of p16/Ki-67 dual staining for triage high risk HPV (HR-HPV) infected women. Method: Target objects were women who infected HR-HPV and received colposcopy examination between April and December of 2016 at the Second Affiliated Hospital of Zhengzhou University. Gynecologists collected the cervical exfoliated cells from eligible women for p16/Ki-67 dual staining, LBC testing and HPV DNA testing. Histology diagnosis were used as gold standard. Sensitivities, specificities, positive predictive values (PPVs), negative predictive values (NPVs) of p16/Ki-67 dual staining, LBC testing and HPV16/18 testing for triage of HR-HPV positive population were calculated and compared. Results: A total of 295 HR-HPV infected women were selected, and the mean age was (44.29±11.48) years old. Positive rates of p16/Ki-67 dual staining, HPV16/18 testing and LBC testing were 70.17% (207), 56.95% (168) and 85.76% (253), respectively. When CIN2+as the endpoint, among the three triage methods, sensitivity of p16/Ki-67 dual staining was 90.00% (95%CI: 85.06%-93.43%), higher than the value of HPV 16/18 testing, but lower than the value of LBC testing. Specificity, PPV and NPV of p16/Ki-67 dual staining were the highest [71.58% (95%CI: 61.81%-79.67%), 86.96% (95%CI:81.69%-90.88%) and 77.27% (95%CI: 67.49%-84.78%)]. When detection for CIN3+, sensitivity of p16/Ki-67 dual staining was 92.90% (95%CI: 87.74%-95.99%), lower than the value of LBC testing, but higher than the value of HPV16/18 testing. Specificity of p16/Ki-67 dual staining was 55.00% (95%CI: 46.74%-63.00%), lower than the value of HPV16/18 testing, but higher than the value of LBC testing. PPV of p16/Ki-67 dual staining was 69.57% (95%CI: 62.99%-75.43%), lower than the value of HPV 16/18 testing, but higher than the value of LBC testing. NPV of p16/Ki-67 dual staining was 87.50% (95%CI: 78.99%-92.87%), higher than value of HPV 16/18 testing, but lower than the value of LBC testing. Conclusion: p16/Ki-67 dual staining has better clinical effects than HPV 16/18 testing and LBC testing for triage women with HR-HPV infection.

Abstract
Objective: To estimate the incidence and mortality of kidney cancer in China in 2014, based on the cancer registration data. Data was collected through the National Central Cancer Registry (NCCR). Methods: All together, 449 cancer registries submitted required data on incidence and deaths of kidney cancer occurred in 2014, to the NCCR. After evaluation on the quality of data,339 registries were accepted for analysis and stratified by areas (urban/rural) and age groups. Combined with data from the National population in 2014, the nationwide incidence and mortality of kidney cancer were estimated. Data from the 2000 National census was used, and with Segi's population used for the rates of age-standardized incidence/mortality. Results: The qualified 339 cancer registries covered a total population of 288 243 347, with 144 061 915 in urban and 144 181 432 in rural areas. The percentage of morphologically verified cases and cases with only available death certificates were 72.70% and 1.27%, respectively. The mortality to incidence ratio was 0.37. The estimates of new cases were around 68 300 in whole China, in 2014, with a crude incidence rate as 4.99/100 000 (95%CI: 4.95/100 000-5.03/100 000). The age-standardized incidence rates of kidney cancer, estimated by China standard population (ASR China) and world standard population (ASR world) were 3.43/100 000 (95%CI: 3.40/100 000-3.46/100 000) and 3.40/100 000 (95%CI: 3.37/100 000- 3.43/100 000), respectively. The cumulative incidence rate of kidney cancer was 0.40% in China. The crude and ASR China incidence rates for males appeared as 6.09/100 000 (6.03/100 000-6.15/100 000) and 4.32/100 000 (4.28/100 000-4.36/100 000), respectively, whereas those were 3.84/100 000 (3.79/100 000-3.89/100 000) and 2.54/100 000 (2.50/100 000-2.58/100 000) for females. The crude and ASR China incidence rates in urban areas appeared as 6.60/100 000 (95%CI: 6.54/100 000-6.66/100 000) and 4.25/100 000 (95%CI: 4.21/100 000-4.29/100 000), respectively, whereas those were 3.05/100 000 (95%CI: 3.01/100 000-3.09/100 000) and 2.29/100 000 (95%CI: 2.25/100 000-2.33/100 000) in rural areas. The estimates of kidney cancer deaths were around 25 600 in the country, in 2014, with a crude mortality rate of 1.87/100 000 (95%CI: 1.85/100 000-1.89/100 000). The ASR China and ASR world mortality rates appeared as 1.16/100 000 (95%CI: 1.14/100 000-1.18/100 000) and 1.16/100 000(95%CI: 1.14/100 000-1.18/100 000), respectively, with a cumulative mortality rate (0-74 years old) of 0.12%. The crude and ASR China mortality rates were 2.31/100 000 (95%CI: 2.27/100 000- 2.35/100 000) and 1.52/100 000 (95%CI: 1.50/100 000-1.54/100 000) for males, respectively, whereas those were 1.41/100 000 (95%CI: 1.38/100 000-1.44/100 000) and 0.81/100 000 (95%CI: 0.79/100 000- 0.83/100 000) for females. The crude and ASR China mortality rates were 2.49/100 000 (95%CI: 2.45/100 000-2.53/100 000) and 1.42/100 000 (95%CI: 1.40/100 000-1.44/100 000) in urban areas, respectively, whereas those were 1.12/100 000 (95%CI: 1.09/100 000-1.15/100 000) and 0.78/100 000 (95%CI: 0.76/100 000-0.80/100 000) in the rural areas. Conclusions: Both the incidence and mortality of kidney cancer seemed low, in China. However, the incidence of kidney cancer had greatly increased. Our findings suggested that prevention and control strategies for kidney cancer should be focused on males in the urban areas.

Abstract
Objective: To study the hemoglobin concentration, anemia status and its determinant factors among Chinese rural women of reproductive age in 2012. Methods: This was a cross-sectional study. The data was obtained from the National Free Preconception Health Examination Project (NFPHEP). A total of 712 101 Chinese rural reproductive age women aged 21-49 years old who came from 193 counties of 30 provinces were included. The demographic characteristics were obtained from questionnaires. Hemoglobin concentration was measured using the cyanomethemoglobin method. The definition of anemia we used was recommended by World Health Organization, and was adjusted according to altitude level. The hemoglobin concentration level, the prevalence of anemia and its 95% CI was calculated. Determinant factors of anemia such as demographic characteristics and histories of pregnancy and miscarriage were analyzed using logistic regression. Results: In 2012, the level of hemoglobin concentration in Chinese rural women of reproductive age was (127.77±13.47) g/L, with the lowest in 21-24 years group, which was (127.54±13.54) g/L, and highest in 35-39 years group, which was (128.39±14.12) g/L. In terms of region, the hemoglobin concentration level was lowest in central south, which was (125.79±12.00) g/L, and highest in southwest, which was (129.91±14.37) g/L. The prevalence of anemia in Chinese rural women of reproductive age was 24.80%, with the highest seen in 21-24 years, which was 25.92% (95% CI: 25.74%-26.11%), and lowest in 30-34 years, which was 23.61% (95% CI: 23.37%-23.85%). The prevalence in northwest (28.31%, 95% CI: 28.01%-28.61%) was the highest among all regions, and the prevalence in east (20.88%, 95% CI: 20.68%-21.09%) was the lowest. Conclusions: The prevalence of anemia in Chinese rural reproductive age women was 24.80% in 2012. The anemia prevalence was higher among women who were young, had low educational level, and lived in northwest region.

Abstract
Objective: To investigate the effect of fried food intake on the pathogenesis of gastric cancer and precancerous lesions. Methods: From 2005 to 2013, the residents aged 40-69 years from 11 counties/cities where cancer screening of upper gastrointestinal cancer were conducted in rural areas of Henan province as the subjects (82 367 cases). The information such as demography and lifestyle was collected. The residents were screened with endoscopic examination. The biopsy sampleswere diagnosed pathologically, according to pathological diagnosis criteria, the subjects with high risk were divided into the groups with different pathological degrees. The multivariate ordinal logistic regression analysis was used to analyze the relationship between the frequency of fried food intake and gastric cancer and precancerous lesions. Results: The study coverd 46 425 males and 35 942 females, with a age of (53.46±8.07)years. The study collected 6 707 cases of normal stomach, 2 325 cases of low grade intraepithelial neoplasia, 226 cases of high grade intraepithelial neoplasia and 331 cases of gastric cancer. Multivariate logistic regression analysis showed that, compared with those whoeat fried food less than one time per week, fried foods intake (<2 times/week: OR=1.89, 95%CI: 1.57-2.28; ≥ 2 times/week: OR=1.91, 95%CI: 1.66-2.20) were a risk factor for gastric cancer and precancerous lesions after adjustment for age, sex, marital status, educational level, body mass index (BMI), smoking and drinking status. Conclusion: The intake of fried food is a risk factor for gastric cancer and precancerous lesions. Therefore, reducing the intake of fried food can prevent the occurrence of gastric carcinoma and precancerous lesions.

Abstract
The emissions characteristics of 16 kinds of polycyclic aromatic hydrocarbons (PAHs) in ambient air during the waste tire retreading process (open-air storage, mixing, vulcanization, and grinding processes) and in workers' dormitory were analyzed. In addition, the occupational health risk of the workers was evaluated. Results showed that PAHs were detected in all retreading processes and in the workers' dormitory. The highest concentration site was the mixing process, followed by open-air storage and vulcanization process. The lowest concentration point was in the grinding process. The average concentration of PAHs in the workers' dormitory was 11.1 ng·m-3. The PAHs at all sampling points were largely phenanthrene (Phe), fluoranthene (Flu), anthracene (Ant), and pyrene (Pry), which also had a stronger linear correlation with the total PAH concentration. An analysis of the benzene rings showed that three ring and four ring were the majority, while two ring, five ring, and six ring components accounted for less than 10%. Results of the possible influencing factors of the PAHs revealed that the open-air storage and dormitory might be affected by a combustion source, but the mixing, vulcanization, and grinding processes might be affected by rubber oil. The principal component analysis (PCA) and cluster analysis showed that the spatial location of all sites would significantly influence the distribution of PAHs during the tire retreading process. The health risk assessment showed that occupational workers had a lower risk of lifelong cancer, and there was little influence on life expectancy.

Abstract
Objective: To evaluate the therapeutic effect of cervical Jiaji electroacupuncture on postoperative intractable hiccup of liver neoplasms. Methods: A total of 39 patients with postoperative intractable hiccup of liver neoplasms in The First Affiliated Hospital of Heilongjiang University of Chinese Medicine from May 2013 to May 2017 were collected and divided into 2 groups randomly. The electroacupuncture group included 20 cases, the control group included 19 cases. Patients in the electroacupuncture group were treated by cervical Jiaji electroacupuncture (located in C3-5, sympathetic ganglion), while the control group were treated by metoclopramide combined with chlorpromazine for three days. The therapeutic effects of two groups were compared and the onset time were recorded. Results: Total effective rates of electroacupuncture group and control group were 95.0% and 47.4%, respectively. The onset time in electroacupuncture group and control group were (14.8±3.3) h and (30.5±3.1) h, respectively (P<0.01). Ten cases who resisted the control treatment were then treated by electroacupuncture for 3 days, 6 cases were recovered, 3 cases became better, while 1 case demonstrated no response. No serious adverse reactions were appeared in each group. Conclusion: Cervical Jiaji electroacupuncture is an effective and safe treatment for postoperative intractable hiccup of liver neoplasms, and it can be used as a remedy for intractable hiccup patients who don't respond to drug treatment.

Abstract
To assess the pollution levels, characteristics, and the pollution sources and occupational inhalation exposure of polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs)in the workshops,ambient air samples in different types of incinerators of two municipal solid waste incinerators(MSWI) were collected and analyzed. The results showed that ① The I-TEQ concentration ranged from 0.034-2.152 pg·m-3in the two waste incineration plants, and the most sites' I-TEQ exceeded the ambient air quality standard. Besides, the I-TEQ concentration behind the incineration plant was higher than others. ② The dioxins in incineration plant were dominated by OCDD and 1,2,3,4,6,7,8-HpCDD. For MSWI A, the flue gas and the fly ash had major effect on PCDD/Fs, while the dioxins pollution in MSWI B was only affected by the fly ash. ③ Occupational inhalation exposure of PCDD/Fs was 0.01-1.10 pg·(kg·d)-1 in incineration plant, some occupational inhalation exposure values exceeded the evaluation standard, and the areas behind the incinerators were evaluated to have a high exposure risk.

Abstract
This paper analyzed 17 polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs) by HRGC/HRMS in the flue gas of a certain municipal solid waste incinerator(MSWI) and its surrounding air and other possible sources in Guangdong. It discussed the feature of homologs and main toxic monomers in all samples. It also investigated the relationship among surrounding area, MSWI and possible sources using principle component analysis (PCA) and cluster analysis. The results showed that the concentration of PCDD/Fs was higher in the flue gas than the ambient air, moreover non-effect suffered by prevailing wind direction. The possible sources might be tyre factory and open burning based on spot survey. The concentration of PCDD/Fs was lower in tyre factory than upwind station, but higher at open burning spot than outdrop monitoring station. The analysis of homologs showed that OCDD, 1,2,3,4,6,7,8-HpCDD and 1,2,3,4,6,7,8-HpCDF were the main materials in the flue gas and air, meanwhile OCDF was also found in atmosphere. There was similar feature of 17 PCDD/Fs between surrounding monitoring station and tyre factory, and the same between flue gas and open burning. The further analysis showed that the linearly dependent coefficients of 1,2,3,7,8-PeCDD and 2,3,4,6,7,8-HxCDF were 0.95 and 0.75, respectively. It showed the strong correlation of two monomers in all ambient air samples. The PCA and cluster analysis showed that MSWI influenced the surrounding air, tyre factory had an impact on upwind station, and open burning had a lower effect on outdrop monitoring station.

Abstract
OBJECTIVE To investigate folic acid (FA) supplementation status among Chinese rural reproductive women in their early pregnancy, and to provide evidence for the evaluation of FA supplementation project from national basic public health services. METHODS The data on intake status of FA supplementation from "National Free Preconception Health Examination Project (NFPHEP)" database between January 1, 2010 and December 31, 2012 was used and analyzed.A total of 902 270 women who achieved follow-up during early pregnancy from 220 pilot counties of 31 provinces were recruited. RESULTS From 2010 to 2012, the rate of FA intake among women recuited were 73.58% (134 131/182 289), 75.88% (329 288/433 970) and 76.53% (218 896/286 011), respectively, which increased year by year (χtrend(2)=13 371.8, P<0.001). Among 682 315 women who took FA, 350 738(51.40%) women began to take FA 3 months before amenorrhea; 130 683 (19.15%) women began to take FA 1-2 months before amenorrhea, and 200 894 (29.44%) began to take FA after amenorrhea.Among 682 315 women who took FA, 645 310 (94.58%) women took it regularly, and 342 418 (50.18%) women took FA in a standardized way. CONCLUSIONS The status of FA intake among Chinese rural women in the first trimester of pregnancy was good, and 75.62% (682 315/902 270) of them took FA.It is also important for basic public health services to improve the rate of FA intake and increase the rate of taking FA in a standardized way in Chinese rural pregnant women.

Abstract
Objective: To investigate the potential dose-response relationship between PCDD/Fs inhalational exposure and oxidative damage to DNA and lipid in foundry workers. Methods: The participants were divided into three groups, including exposure group, administrator group and control group. The concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in air environment were determined by isotope dilution high resolution capillary column gas chromatography/high resolution mass spectrometry (HRGC-HRMS). The inhalational dose of PCDD/Fs were evaluated by Houmen's model. Urinary 8-OHdG was analyzed by high performance liquid chromatography-electrochemical detector (HPLC-ECD). Urinary 8-iso-PGF2ɑ were determined by ELISA. Results: The PCDD/Fs environmental concentrations of three groups (pg·TEQ/m) were 0.21±0.08, 0.03±0.01, 0.0012±0.0007 (P<0.05) , respectively. The inhalational dose of exposure group (92.54 (32.90~264.49) fg·TEQ/kg·d) was 5.4 folds higher than the administrator group, and was 201 times more than control group. The levels of urinary 8-OHdG (nmol/L crea) of three groups were 3.25 (1.07~15.36) , 2.72 (0.75~16.07) , 2.17 (0.38~17.07) (P<0.05) and the levels of urinary 8-iso-PGF2ɑ (nmol/L crea) were 19.11 (9.33~76.50) , 20.95 (8.40~79.31) , 11.48 (4.85~37.80) (P<0.05) , respectively. The multiple linear regression analysis revealed that there were significantly increased trend for levels of urinary 8-OHdG and 8-iso-PGF2ɑ as PCDD/Fs exposure levels increased, after adjustment for age, sex, smoking statue, alcohol use and BMI (P<0.01). Conclusion: There was a dose-response relationship between PCDD/Fs inhalational exposure and oxidative damage in foundry workers.

Abstract
Endotoxin lipopolysaccharide (LPS) affects the ruminant health and animal performance. The main purposes of this study were to investigate the potential effects of GH/IGF system and lipoprotein lipase (LPL) concentration on resistance the circulating LPS concentration increased in liver with high concentrate diet treatment. Non-lactating goats were randomly allocated to two groups: a high-concentrate diet (HCD) or a low-concentrate diet (LCD) in cross over design and the blood collection at different time points after feeding at the end of the experiment. The average rumen pH was significantly reduced (P<0.05), but the duration with pH was not more than 120 min in the HCD group. The plasma LPL concentration was significantly raised (P<0.05). However, from 2 h onwards, LPS concentration was significantly reduced (P<0.01) in the HCD group compared with LCD group. In addition, the plasma IGF1 concentration and the hepatic insulin-like growth factor-1 receptor (IGF1R) mRNA expression were markedly reduced (P<0.05). However, growth hormone (GH) secretion at 15, 30, and 45 min after feeding and growth hormone receptor (GHR) mRNA expression in the liver was significantly increased (P<0.05) in HCD group. The correlation analysis showed that the plasma LPL concentration was positively correlated with hepatic GHR mRNA expression (P<0.05). Conversely, the plasma LPS concentration was negatively correlated with LPL concentration (P<0.05). These findings reveal that alterations in GH/IGF system function in response to a high-concentrate diet are accompanied by corresponding changes in systemic LPL in non-lactating goats' liver in presence of endogenous LPS stress.

Abstract
High-resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS) was used to measure contents of 2, 3, 7, 8-polychlorinated dibenzo-p-dioxin and furan (PCDD/F) in ambient air in Guangzhou city, and its sources were traced and tracked preliminarily. Spatial and seasonal distributions, the correlation between PCDD/F concentrations and various kinds of meteorological factors were studied with emphasis, as well as the trajectory of air mass simulated by hybrid single-particle lagrangian integrated trajectory (HYSPLIT) model of the U. S. A Air Resources Laboratory, which will provide important basic data for understanding PCDD/F pollution levels in urban regions. The results show, PCDD/F concentrations in the industrial area are higher than others, and in spring, PCDD/F TEQs are the highest. Meteorological factors, like wind direction and speed, temperature, air pressure, relative humidity, precipitation all have influence on pollution levels of atmospheric PCDD/Fs. Temperature and wind speed has a negative correlation with the concentration, but it is not obvious. By the analysis of the backward trajectory of air mass, something are obtained that the trajectory extends mainly to northwest areas in autumn, and air masses from inland migrate slowly in winter, while they arrive at Guangzhou after passing southeast coast or sea.

Abstract
The aim of this study was to evaluate protein expression patterns of liver in response to subacute ruminal acidosis (SARA) induced by high-concentrate diet. Sixteen healthy mid-lactating goats were randomly divided into 2 groups and fed either a high-forage (HF) diet or a high-concentrate (HC) diet. The HC diet was expected to induce SARA. After ensuring the occurrence of SARA, liver samples were collected. Proteome analysis with differential in gel electrophoresis technology revealed that, 15 proteins were significantly modulated in liver in a comparison between HF and HC-fed goats. These proteins were found mainly associated with metabolism and energy transfer after identified by matrix-assisted laser desorption ionization/time of flight. The results indicated that glucose, lipid and protein catabolism could be enhanced when SARA occurred. It prompted that glucose, lipid and amine acid in the liver mainly participated in oxidation and energy supply when SARA occurred, which possibly consumed more precursors involved in milk protein and milk fat synthesis. These results suggest new candidate proteins that may contribute to a better understanding of the mechanisms that mediate liver adaptation to SARA.

Abstract
Concentrations and distribution characteristics of 2,3,7,8-substituted polychlorinated dibenzo-p-dioxins and dibenzofurans (2,3,7,8-PCDD/Fs) were analyzed in waste water from a paper mill. And concentrations of 2,3,7,8-PCDD/Fs in waste water before and after electron beam irradiation with different doses were compared. The feasibility, mechanism and rates of 2,3,7,8-PCDD/Fs degradation were discussed. The PCDD/Fs concentrations and corresponding I-TEQ (toxic equivalent quantity) values were 239 pg x L(-1) and 41.0 pg x L(-1), respectively, in the waste water. The concentrations of total 2,3,7,8-PCDD/Fs decreased after electron beam radiolysis at a dose of 30 kGy and 60 kGy with degradation rates of 5.27% and 23.6%, respectively.

Abstract
Atmospheric concentrations of 2,3,7,8-substituted polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were measured seasonally in an industrial area of Guangzhou City. And seasonal variation of concentrations and distribution characteristics of 2,3,7,8- PCDD/Fs was investigated. The PCDD/Fs concentrations and corresponding I-TEQ (toxic equivalent quantity) values were in the range of 2.33-75.4 pg x m(-3) (mean = 23.2 pg x m(-3)) and 0.229-10.7 pg x m(-3) (mean = 2.00 pg x m(-3)), respectively. The seasonal variation of PCDD/Fs concentrations was obvious, with the highest concentration was found in spring (37.8 pg x m(-3)) and the lowest in summer (13.5 pg x m(-3)). However, no obvious difference of concentrations was observed for autumn (22.3 pg x m(-3)) and winter (19.1 pg x m(-3)). The seasonal variation of I-TEQ values is as follows: spring (5.58 pg x m(-3)) > summer (1.06 pg x m(-3)) > autumn (0.839 pg x m(-3)) > winter (0.525 pg x m(-3)). The influences of monsoon and rainfall on the concentration of PCDD/Fs in atmosphere are discussed.

Abstract
The concentration and profiles of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in the environmental air, soil and plant samples around a hospital solid waste incinerator (HSWI) in Northwest of China were determined by HRGC/HRMS, and the flue gas samples of the HSWI were also involved. The results showed that the average concentration (I-TEQ) of PCDD/Fs in the exhaust gas was 184 ng x m(-3), which seriously exceeds the emission standard (0.5 ng x m(-3)). And the average concentration of PCDD/ Fs was 7.30 pg x m(-3) in the ambient air samples, 52.5 pg x g(-1) in the soil samples, and 146 pg x g(-1) in the leaves samples. All of them were at quite high levels. The concentrations of PCDD/Fs in air samples of downwind were obviously higher than those of upwind. The concentration increased and then decreased with the increase of distance from the HSWI, and the highest concentration occurred at the distance of 700 m from the HSWI. The mass concentration (I-TEQ) proportional distributions of 2, 3, 7, 8 substitution toxic dioxins in downwind air and soil samples was similar to those in the exhaust gas samples. The analysis results of PCDD/Fs concentrations, profiles distributions and principal components all showed that the major source of PCDD/Fs in this area was from the HSWI flue gas emissions.

Abstract
AIMS The standard surgical procedure for elderly (≥ 70 years) patients with clinical stage I non-small cell lung cancer (NSCLC) was investigated. METHODS A non-randomized prospective controlled study was conducted to compare lobectomy with segmental resection for the treatment of elderly clinical stage I lung cancer patients under different pulmonary function. Perioperative indicators including time and volume of thoracic drainage, incidence of postoperative complications, locoregional recurrence rates, and 1, 3, and 5-year survival rates were analyzed. RESULTS A total of 184 patients were included in the study. Patients were classified into two groups according to pulmonary function: group 1 included 64 patients who had poor pulmonary function, with a forced expiratory volume in 1 s (FEV(1)) of less than 1.5 L, whereas group 2 consisted of 120 patients with an FEV(1) ≥ 1.5 L. The patients in group 1 had a longer postoperative mechanical ventilation time and a higher incidence rate of respiratory associated complications than those in group 2 (21.9 vs. 8.35%, p = 0.009). The local recurrence and long-term survival rates were not significantly different between lobectomy and segmental resection. Among the patients who underwent segmental resection, those who had regional lymph node dissection showed a higher 3-year and 5-year survival rate than those undergoing selected lymph node resection (77.8 vs. 51.7%, p = 0.042; 55.6 vs. 27.6%, p = 0.034), but this was not significant in lobectomy. CONCLUSIONS Segmental resection combined with regional lymph node resection could be the best choice for elderly clinical stage I NSCLC patients with FEV(1) < 1.5 L.

Abstract
Fifty-two house dust samples were randomly collected in Guangzhou and Haikou City, to analyze the concentrations of Sigma10 PBDEs (sum of BDE 28, 47, 66, 85, 99, 100, 153, 154, 183 and 209), the PBDE composition profiles, and possible influencing factors, and estimate human exposure to PBDEs via dust ingestion for adults and toddlers. The results showed that PBDEs were found in all samples, with the Sigma10 PBDEs concentrations ranging from 544.2 ng/g to 9 654 ng/g, and with median (mean) of 2 547 (3 096) ng/g. The PBDE levels in Guangzhou samples were obviously higher than those in Haikou. No significant correlations between PBDE levels and residential characteristics (number of TVs, computers, and polyurethane foam-contained furniture, time of using TVs and computers) were observed. BDE209, with a mean concentration of 3 021 ng/g, was the dominated congener, contributing 73.70%-99.74% to the Sigma10 PBDEs, with a mean contribution of 96.85%. BDE 47, 99 and 183 were the most abundant congeners of Sigma9 PBDEs (BDE 209 excluded), with a mean contribution of 24.48%, 23.99%, and 21.66%, respectively. There is no notable difference in PBDE composition between Guangzhou and Haikou samples. The estimated exposure for adults and toddlers to PBDEs ranged from 10.59 ng/d to 254.7 ng/d and from 140.1 ng/d to 509.3 ng/d, respectively. Due to their increased dust ingestion rates, toddlers in took more PBDEs via dust ingestion than adults. Dust ingestion was an important human exposure route for PBDEs, especially for toddlers.

Abstract
In the present study, 16 polycyclic aromatic hydrocarbons (PAHs) in the surface sediment from Beijiang River in China were quantitatively determined by GC/MS. The concentration of PAHs varied from 38.2 to 6470 ng x g(-1) dry weight, with average 1071 ng x g(-1), which was in moderate level compared with other rivers in Pear River Basin. The PAHs distribution in Bejiang River was obviously affected by point source emissions. The high PAHs concentrations of 6470 ng x g(-1) and 4 470 ng x g(-1) were found at the outfalls of Shaoye and the Shakou town, respectively, where PAHs probably derived from local mining/smelting and related industrial actives. The ecological risk of surface sediment in Beijiang River was assessed with the methods of sediment quality guidelines (SQGs), sediment quality standards (SQSs) and contamination factors (CFs) . The result shows that the adverse biological toxicity effect might occasionally happen in more than half of sampling stations. By comparison with the background area, the contamination degrees of PAHs in 20 sampling stations were at very high level, which should arrest the local governments' attentions. The highest ecological risk areas occurred at the outfalls of Shaoye and the Shakou town in which the ecological risks derived from PAHs were within between probable effect level (PEL) and frequent effect level (FEL). The future research was suggested mainly focusing on the status of benthos, sources of pollutants and ways to control pollution in high-risk areas.

Abstract
OBJECTIVE The objectives of this study are to understand the current functions, structure and operation of hospital ethics committees (HECs) in Shanghai and to facilitate their improvement. METHODS (1) A questionnaire survey, (2) interviews with secretaries and (3) on-site document reviews of HECs in Shanghai were used in the study, which surveyed 33 hospitals. RESULTS In Shanghai, 57.56% of the surveyed hospitals established HECs from 1998 to 2005. Most HECs used bioethical review of research involving human subjects as well as bioethical review or consultation regarding medical care services and administrative decision- making. Of the surveyed HECs, 14.3% did not provide any formal bioethical training to the HECs' members and many HECs had no standard operating procedures. Some HECs had no clear definition of what was "conflict of interest" that should be considered by the HECs, while 44.4% of the HECs did not perform continuing review. DISCUSSION After the issues of related national regulations, more and more hospitals established HECs in Shanghai, but the functions of HECs need to be further developed and formal training on bioethics should be provided to HEC members. To assure the independence and good performance of HECs, the conflict of interest procedure, the standard operating procedures and bioethical review should be improved. CONCLUSION HECs in Shanghai had developed in the preceding 10 years and they played great roles in protecting the rights and welfare of human subjects and patients; some areas need improvement.

Abstract
OBJECTIVE To clone and analyze novel antigen molecules of Schistosoma japonicum (Sj), and to provide effective vaccine candidate antigens against schistosomiasis japonica. METHODS Sj adult cDNA library was screened using sera of mice infected with Trichinella spiralis (Ts) and the inserts of positive clones were specifically amplified by PCR. The positive clones were sequenced and the sequence data were analyzed using Nucleotide BLAST software of NCBI and Expert Protein Analysis System of Swiss Institute of Bioinformatics. RESULTS Nine positive clones were obtained after three rounds of immunoscreening. The size of these inserts ranged from 0.6 kb to 2.1 kb. Among five novel genes, Sj-Ts1, Sj-Ts3 and Sj-Ts5 (GenBank accession number: AY005816, AF299080 and AY024352, respectively) encode trans-membrane proteins with 83, 83 and 233 amino acids, respectively. Sj-Ts1 protein predicted contains one possible trans-membrance helix, one N-myristoylation site, two phosphorylation sites for protein kinase C and one for tyrosine kinase, Sj-Ts3 protein contains two possible transmembrance helices and one casein kinase II phosphorylation site, whereas Sj-Ts5 protein has five possible transmembrance helices, one N-glycosylation site, one N-myristoylation site, two phosphorylation sites for cAMP- and cGMP-dependent protein kinase and four for protein kinase C and one for casein kinase II. CONCLUSION Three novel genes encoding three transmembrane proteins might be developed as new vaccine candidates against Sj infection.

Abstract
OBJECTIVE To evaluate the specificity and sensitivity of SjMAg in detecting specific antibodies in sera of patients with schistosomiasis japonica and in assessing therapeutic efficacy. METHODS SjMAg-ELISA was used to determine the specific IgG and IgG4 in sera of patients with schistosomiasis japonica at different time points after chemotherapy. RESULTS SjMAg-ELISA was as sensitive and specific as SEA-ELISA. The negative conversion rate of IgG detected by SjMAg-ELISA 12 months after treatment was 80.0%, being significantly higher than 43.3% by SEA-ELISA. The negative conversion rate of IgG4 detected by SjMAg-ELISA 12 months after treatment was 93.3%, being significantly higher than 60.0% by SEA-ELISA. The negative conversion rates of IgG and IgG4 2 yr after treatment were 92.9% and 97.6% respectively. CONCLUSION SjMAg-ELISA is comparable to SEA-ELISA in diagnosing schistosomiasis japonica and is more effective in assessing therapeutic efficacy.

Abstract
We demonstrate spin transport and spin lifetime enhancement in GaAs quantum wells induced by the traveling piezoelectric field of a surface acoustic wave (SAW). Spin transport lengths of about 3 microm corresponding to spin relaxation times during transport over 1 ns are observed, which are considerably longer than the exciton spin diffusion lengths in the absence of a SAW. The slow spin relaxation is attributed to a reduced electron-hole exchange interaction, when the carriers are spatially separated by the lateral potential modulation induced by the SAW.

Thirty-three egg-positive subjects and 32 egg-negative subjects were tested synchronously by KLH-IDT and SEA-IDT in endemic area of schistosomiasis. Compared with stool examination, the positive coincidence rate of KLH-IDT and SEA-IDT were 90% and 100%, respectively, which showed no statistical significance(P > 0.05), and the negative coincidence rate of KLH-IDT and SEA-IDT were 71.9% and 25%, respectively, which showed statistical significance(P < 0.01). Of the 31 egg-negative subjects, 9 subjects showed positive by both SEA-IDT and KLH-IDT, and 15 subjects showed positive by SEA-IDT but negative by KLH-IDT. Both double positive subjects and single positive subjects were examined further by miracidium hatching test, there were 2 subjects showing positive among the 9 double positive subjects. In addition, of 27 subjects that had been treated one year before, only 6 subjects showed positive by KLH-IDT, the reversion rate was 77.8%; whereas, the reversion rate was 22.2% (6/21) by SEA-IDT. The results suggest that KLH-IDT has high value in diagnosing schistosomiasis, particularly shows a potential in assessing therapeutic efficacy of schistosomiasis.
