ABSTRACT
Objective:To evaluate the performance of rural practitioners of endoscopic cleaning and disinfection participating in the Early Diagnosis and Treatment Program for Upper Gastrointestinal Cancers and to analyze the influencing factors.Methods:The questionnaires for skill assessment were designed based on the skill scheme and clinical practice of the Early Diagnosis and Treatment Program for Upper Gastrointestinal Cancers in rural China, and the App Early diagnosis, Early treatment was used as the examination platform. The practitioners in 539 county hospitals from 25 provinces participating in the program in 2019 were assessed for techniques and skills for endoscopic cleaning and disinfection and the excellence rate was calculated. Multivariate logistic regression model was used to analyze the influencing factors for the examination. Results:A total of 1 671 endoscopic cleaning and disinfection practitioners participated in the assessment with the score of 73.41±16.60. The passing rate was 85.82%, and the excellence rate was 44.94%. Among all questions, the correct rate of "opportunistic screening flow chart" was the highest (98.21%), and that of "the evaluation index for mass screening" was the lowest (57.89%). The multivariate logistic regression analysis showed that the excellence rate was high in practitioners who had a bachelor degree or above ( OR=1.627,95% CI:1.319-2.007, P<0.001), the career for 5 to <15 years (5 to <10 years: OR=1.329,95% CI:1.045-1.689, P=0.020; 10 to <15 years: OR=1.384,95% CI:1.026-1.867, P=0.033), working in eastern and central regions (eastern regions: OR=3.476,95% CI:2.368-5.103, P<0.001;central regions: OR=4.028,95% CI:2.679-6.057, P<0.001) and with full understanding of the screening scheme ( OR=1.547,95% CI:1.246-1.921, P<0.001) . Conclusion:Practitioners on the Early Diagnosis and Treatment Program for Upper Gastrointestinal Cancers in rural China have mastered the basic screening scheme and skills for endoscopic cleaning and disinfection. The education background, duration of the career, area and understanding of screening scheme are influencing factors for the excellence rate of endoscopic cleaning and disinfection.
ABSTRACT
Objective:To realize the understanding level of cancer awareness of residents in Shanxi Province, and to provide a scientific basis for cancer prevention and treatment.Methods:In April 2020, 1 897 local residents in Shanxi Province were recruited to fill in the core knowledge questionnaire of cancer prevention and treatment. The basic demographic information and the core knowledge of cancer prevention and control were collected, and the influencing factors for the understanding of the core knowledge of cancer prevention and treatment were analyzed by using multivariate logistic regression model.Results:In the survey on the awareness rate of core knowledge of cancer prevention and control among residents in Shanxi Province, 37 940 items were answered, among which 29 396 items were known, and the awareness rate of the population was 77.48% (29 396/37 940). The single-factor results showed that there were statistically significant differences in awareness rates of core knowledge of cancer prevention and treatment among the population with different gender, household registration, ethnic groups, education degree, occupation and different frequency of the health examination were statistically significant (all P < 0.05); there were no statistically significant differences in awareness rates of core knowledge among the population with different age, and smokers or non-smokers (all P >0.05).Multivariate logistic regression analysis showed that education degree of junior middle school or above ( OR = 3.412-16.767, 95% CI 1.755-32.476) and receiving physical examination once a year ( OR = 2.291, 95% CI 1.154-4.549) were the favorable factors for knowing the core knowledge of cancer prevention and treatment. Household location in rural area ( OR = 0.522, 95% CI 0.378-0.722) and non-Han nationality ( OR = 0.369, 95% CI 0.151-0.904) were the unfavorable factors for knowing the core knowledge of cancer prevention and treatment. Conclusions:The awareness of core knowledge of cancer prevention and treatment among residents in Shanxi Province is good, so it is necessary to continue to strengthen the publicity of cancer prevention and control and improve the awareness of cancer prevention and control in the future.
ABSTRACT
Objective:To investigate the incidence and mortality of lung cancer in the cancer registration areas of Shanxi Province in 2017.Methods:The cancer registration data reported by 12 tumor registration areas of Shanxi in 2017 were sorted out and stratified by urban and rural areas and gender. The number of incidence and death ,the crude incidence and mortality, the cumulative rate (0-74 years), age-specific incidence and mortality, Chinese population standardized rate and world population standardized rate were calculated. The incidence and mortality were standardized by the 2000 China census standard population composition and Segi's world standard population composition.Results:In 2017, there were 2 275 new cases and 1 736 deaths of lung cancer in the tumor registration area of Shanxi Province. The crude incidence rate of lung cancer was 46.72/100 000 (male 63.99/100 000, female 28.80/100 000, urban area 58.05/100 000, rural area 39.09/100 000), Chinese population standardized rate was 31.67/100 000, the world population standardized rate was 32.10/100 000, and the cumulative rate (0-74 years) was 3.87/100 000. The crude mortality rate was 35.65/100,000 (male 49.84/100,000, female 20.93/100,000, urban area 44.53/100,000, rural area 29.67/100 000), Chinese population standardized rate was 23.82/100 000, the world population standardized rate was 24.14/100 000, and the cumulative rate (0-74 years) was 2.69/100,000. Overall, the age-specific incidence and mortality of lung cancer in 2017 were at a low level in 0-44 years age group, and increased rapidly after 45 years age group, and reached a peak in 85 years age group. The incidence and mortality of lung cancer in males were higher than that in females. Although there were some differences in the incidence and mortality of patients with different ago range in urban and rural areas, the overall trend was similar.Conclusions:Lung cancer is the most common malignant tumor threatening the health of residents in Shanxi Province. Male, urban areas and middle-aged and elderly population are the focus of cancer prevention and control in Shanxi Province. Lung cancer prevention and control should be targeted carried out according to the differences between urban and rural areas and gender.
ABSTRACT
Objective@#To investigate the demand and access to the cancer prevention and treatment knowledge and related factors among urban residents in China from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of general demographic characteristics, the demand and access to cancer prevention and treatment knowledge, and the influencing factors of the attitude. The Chi-square test was used to analyze the difference of the demand of the cancer prevention knowledge among different groups and the corresponding factors of the cancer prevention and treatment knowledge were analyzed by using the logistic regression model.@*Results@#The proportion of residents who need the cancer prevention and treatment knowledge was 79.5%. The demand rate of the inducement, symptom and diagnosis methods of cancer in the occupational population was highest, about 66.8%, 71.0% and 20.8%, respectively. The demand rate of treatment methods and cost in current cancer patients was the highest, about the 45.9% and 21.9%, respectively. The top three sources to acquire the cancer prevention and treatment knowledge were "broadcast or television" (69.5%), "books, newspapers, posters or brochures" (44.7%) and "family and friends" (33.8%). The multivariate analysis showed that compared with public institution personnel/civil servants, unmarried/cohabiting/divorced/widowed and others, annual household income less than 20 000 CNY, from the eastern region, people without cancer diagnosis and people with self-assessment of cancer risk, the demand rate of cancer prevention and treatment knowledge was higher in enterprise personnel/workers, married, annual household income between 60 000 CNY and 150 000 CNY, from the central region, people with cancer and people with unclear cancer risk (all P values <0.05).@*Conclusion@#There was a high demand for the cancer prevention and treatment knowledge among urban residents in China from 2015 to 2017. The main access to the knowledge is from the radio or television. The occupation, marital status, annual household income, residential region, health status and risk of disease were the main factors of the demand of the cancer prevention and treatment knowledge.
ABSTRACT
Objective@#To understand the health literacy of the cancer prevention and treatment among urban residents of China, and explore the related factors.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The health literacy of the cancer prevention, early discovery, early diagnosis, early treatment and the demands of cancer prevention and treatment knowledge was analyzed. The level of health literacy among different groups were calculated and compared. The binary logistic regression model was used to analyze the influencing factors of the health literacy of the cancer prevention and treatment.@*Results@#The level of health literacy of the cancer prevention and treatment was 56.97% among all study population; in each group it was 55.01% for community residents, 59.08% for cancer risk assessment/screening population, 61.99% for cancer patients and 57.31% for occupational population, respectively (P<0.001). The level of health literacy of the cancer prevention and treatment of residents aged 50 to 69 years old, other occupational groups, unmarried, the central and western region residents and the group with unclear self-assessment of cancer risk was significantly lower than that of residents younger than 40 years old, personnel of public institutions/civil servants, married, the eastern region residents and the group whose self-assessment without cancer risk (P<0.05) . The level of health literacy of cancer prevention and treatment of females, people who went to high school or over, cancer risk assessment/screening population, cancer patients and occupational population was significantly higher than that of males, people who had an education level of primary school or below and community residents (P<0.05) .@*Conclusion@#The health literacy of the cancer prevention and treatment of urban residents in China was relatively high, but there was still room for improvement. Gender, age, educational level, occupation, region, marital status, self-assessment of cancer risk, and type of respondents were the key influencing factors of the health literacy of the cancer prevention and treatment. Male, 50-69 years old, lower educational level, central and western regions, unclear cancer risk self-assessment, and without specific environmental exposure to cancer prevention and treatment knowledge or related risk factors were the characteristics of the key intervention group of the health literacy of the cancer prevention and treatment.
ABSTRACT
Objective@#To understand the consciousness of the cancer early treatment and its demographic and socioeconomic factors.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The questionnaire collected personal information, the consciousness of the cancer early treatment and relevant factors. The Chi square test was used to compare the difference between the consciousness of the cancer early treatment and relevant factors among the four groups. The logistic regression model was used to analyze the influencing factors related to the consciousness of the cancer early treatment.@*Results@#With the assumption of being diagnosed as precancer or cancer, 89.97% of community residents, 91.84% of cancer risk assessment/screening population, 93.00% of cancer patients and 91.52% of occupational population would accept active treatments (P<0.001). If the immediate family members were diagnosed as precancer or cancer, people who would encourage their family members to receive early treatment in the four groups accounted for 91.96%, 91.94%, 92.44% and 91.55%, respectively (P<0.001). The company employees, annual household income with 40 000 yuan and more and other three groups had a relatively better consciousness of the cancer early treatment (P<0.05). Male, widowed, unemployed and from the central and western regions had a relatively worse consciousness of the cancer early treatment (P<0.05).@*Conclusion@#Residents in urban China participants had a good consciousness of the cancer early treatment. The marital status, occupation, annual household income and residential regions were major factors related to the consciousness of the cancer early treatment.
ABSTRACT
Objective@#To understand the consciousness of the cancer early diagnosis among urban residents and identify the related factors from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The general demographic characteristics, the consciousness of the cancer early diagnosis (whether people would have a willingness or encourage their relatives/friends to confirm the abnormal results once which were detected from the physical examination) and other information were collected by using the self-designed questionnaire. The non-conditional logistic regression model was used to identify the relateol factors related to the consciousness of the cancer early diagnosis.@*Results@#As for residents with abnormal result from the physical examination, 89.29% (28 802) of residents would choose to seek medical treatment for further diagnosis. If their relatives/friends had abnormal results from the physical examination, 89.55% (28 886) of residents would encourage their relatives/friends to confirm the diagnosis in time. The non-conditional logistic regression model analysis showed that compared with the public institution staff/civil servants, annual household income less than 20 000 CNY, the western region and the cancer risk assessment/screening intervention population, the company staff, annual household income about 40 000 CNY and more, and the residents from the middle and eastern region had a stronger consciousness to seek further diagnosis; while the unemployed residents and community residents were less likely to seek further diagnosis (P<0.05).@*Conclusions@#From 2015 to 2017, the Chinese urban residents had a good consciousness of the cancer early diagnosis. Occupation, annual household income, residential region and population group were related to the consciousness of the cancer early diagnosis.
ABSTRACT
Objective@#To understand the consciousness of the cancer early detection among urban residents and identify the influencing factors from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. Self-designed questionnaires were used to collect population, socioeconomic indicators, self-cancer risk assessment, regular participation in physical examination and other information. The multivariate logistic regression model was used to identify the factors of people who had not regularly participated in the regular physical examination in the past five years.@*Results@#The self-assessment results of 32 357 residents showed that there were 27.54% (8 882) of total study population with self-reported cancer risk, 45.48% (14 671) without cancer risk and 26.98% (8 704) with unclear judgement on their own cancer risk. Among population with cancer risk, 79.84% (7 091) considered physical examination accounted. In the past five years, there were 21 105 (65.43%) residents participated in regular physical examination and 11 148 (34.56%) participated in non-scheduled one, respectively. The multivariate logistic regression analysis showed that compared with unmarried and western region residents, divorced, middle and eastern region residents had a stronger consciousness to participate in the regular physical examination (P<0.05). Compare with residents with annual household income less than 20 000 CNY in 2014, cancer risk assessment/screening intervention population, and self-assessment with cancer risk, residents with annual household income between 20 000 CNY and 59 000 CNY in 2014, occupational population, community residents, cancer patients, self-reported cancer-free risk, and self-assessment with unclear judgement of cancer risk were less likely to participate in the regular physical examination (all P values <0.05).@*Conclusion@#From 2015 to 2017, the Chinese urban residents had a acceptable consciousness of the cancer early detection. The marital status, annual household income, population group and self-assessment of cancer risk were related to the consciousness of the cancer early detection of people who had not participated in the regular physical examination in the past five years.

A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors.@*Results@#The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05).@*Conclusion@#The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.
ABSTRACT
Objective:To explore the cancer incidence and mortality in registration areas of Shanxi Province in 2014.Methods:The data of 12 cancer registration areas of Shanxi Province in 2014 were taken to analyze the characteristics of cancer incidence and mortality for patients with different age and gender in different areas. And then the results were compared with the malignant cancer incidence and mortality in the nationwide.Results:There were 11 703 new cases, including 6 559 males and 5 144 females in registration areas of Shanxi Province in 2014, and the incidence rate was 221.21/10 5, while the age-standardized incidence rate of Chinese population and world population was 163.91/10 5 and 163.25/10 5, respectively. The cancer incidence rate in urban areas was 247.02/10 5 and the age-standardized incidence rate of Chinese population was 171.35/10 5. In rural areas, the cancer incidence rate was 205.98/10 5 and the age-standardized incidence rate of Chinese population was 159.03/10 5. The common cancer sites were stomach, lung, esophagus, liver and colorectum for males. And breast, cervix, lung, esophagus, stomach were the common cancer sites for females. There were 7 283 malignant death cases, including 4 548 males and 2 735 females. The crude cancer mortality rate was 137.66/10 5, and the age-standardized mortality rate of Chinese population was 99.67/10 5 and world population was 100.11/10 5. The crude cancer mortality rate in urban areas was 141.03/10 5 and the age-standardized incidence rate of Chinese population was 92.84/10 5. In rural areas, the crude cancer mortality rate was 135.68/10 5 and the age-standardized mortality rate of Chinese population was 103.69/10 5. Male common malignant tumor deaths included lung cancer, gastric cancer, liver cancer, esophageal cancer and colorectal cancer, while lung, stomach, liver, esophagus and cervix were the common cancer death sites for females. Conclusions:The incidence and mortality of malignant tumors in registration areas in Shanxi Province are mainly lung cancer, upper gastrointestinal cancer and cervix uteri cancer.

ABSTRACT
Objective@#To describe the status of non-steroidal anti-inflammatory drugs (NSAIDs) use in areas with a high incidence of upper gastrointestinal cancer in China. @*Methods@#This study was based on the National Key Research and Development Program of "National Precision Medicine Cohort of Esophageal Cancer" and "Study on Identification and Prevention of High-risk Populations of Gastrointestinal Malignancies (Esophageal cancer, Gastric cancer and Colorectal cancer)" . From January 2017 to August 2018, 212 villages or communities with a high incidence of esophageal cancer or gastric cancer were selected from 12 regions in 6 provinces. A total of 35 910 residents aged between 40 and 69 years old who met the inclusion criteria and signed the informed consent were investigated and enrolled in this study. The use of NSAIDs, demographic characteristics, health-related habits, height, weight, and blood pressure were collected by the questionnaire and physical examination. The status of main NSAIDs (aspirin, acetaminophen and ibuprofen) use with the difference varying in genders, age groups and regions were analyzed by using χ2 test and Cochran-Armitage trend analysis method. @*Results@#Of 35 910 subjects, the mean age was (54.6±7.1) years old and males accounted for 43.42% (15 591). The overall prevalence of NSAIDs intake was 4.56% (1 638), but it significantly varied in different provinces (P<0.001). The overall prevalence of NSAIDs intake was 4.87% (1 750) in females, which was significantly higher than that in males 4.24% (1 524) (P<0.001). The prevalence of NSAIDs intake increased with age (P for trend <0.001). As the frequency of NSAIDs intake increased, the incidence of gastrointestinal symptoms, gastrointestinal ulcers and black stools increased (P for trend <0.05 for all). @*Conclusion@#The use of NSAIDs is prevalent in some areas with a high incidence of upper gastrointestinal cancer in China. The increased use of NSAIDs may lead to more adverse effects related to the gastrointestinal tract.
ABSTRACT
Objective To evaluate the value of human papillomavirus (HPV) 16/18 E6 protein detection in shunting and prognosis in patients with atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions (LSIL). Methods A total of 98 patients with ASCUS or LSIL from the Affiliated Cancer Hospital of Shanxi Medical University between May 2014 and May 2015 were selected as the subjects. All of them received the thin-cytologic test (TCT), HPV DNA, HPV16/18 E6 protein tests and colposcopy examination. After 3-year follow-up of patients with cervical intraepithelial neoplasia (CIN) grade Ⅰor bellow lesions diagnosed by biopsy and 30 negative controls, the above tests were performed again. The efficacies of all the tests were analyzed. The value of CIN grade Ⅱ or above was predicted. Results The sensitivity, specificity, positive predictive value and negative predictive value in predicting CIN grade Ⅱor above lesions of HPV16/18 E6 protein , HPV DNA and HPV16/18 DNA was 30.8％, 95.3％, 50.0％, 90.0％, respectively; 84.6％, 37.6％, 17.2％, 94.1％, respectively and 61.5％, 67.1％, 22.2％, 91.9％, respectively in shunting study. The relative risk (RR) of CIN grade Ⅱor above lesions in patients with positive HPV16/18 E6 protein, persistent positive HPV16/18 DNA and positive HPV16/18 DNA was 13.429, 10.231 and 8.343, respectively in the follow-up study. Odds ratio (OR) of HPV16/18 E6 positive protein presenting persistent positive HPV16/18 DNA was 34.833 (95％ CI 5.020-241.711). Conclusions In patients with ASCUS and LSIL, the specificity and positive predictive value of HPV16/18 E6 protein in predicting CIN grade Ⅱ or above lesions are higher than those of HPV DNA and HPV16/18 DNA. Moreover, these patients with HPV16/18 E6 protein positive have a higher risk of developing CIN grade Ⅱ or above lesions and persistent positive HPV16/18 DNA.
ABSTRACT
Objective To understand the incidence and mortality of malignancies as well as tumor burden of Shouyang County, Shanxi Province in 2012. Methods According to the review methods and the standards from the National Cancer Registry, the data of the incidence and mortality of malignant tumors in Shouyang County in 2012 were collected, collated and statistically analyzed. Results There were 389 new malignancies cases of Shouyang County in 2012, including 210 males and 179 females. The incidence rate was 187.61/100000 (190.00/100000 in males and 184.88/100000 in females). There were 263 death cases , including 164 males and 99 females. The mortality rate was 126.84/100000 (148.38/100000 in males and 102.25/100000 in females). The top 10 incidence of malignancies of the whole county was followed by lung cancer, cervical cancer, gastric cancer, liver cancer, colorectal anal cancer, esophageal cancer, breast cancer, bladder cancer, gallbladder cancer and uterus cancer, accounting for 86.12 ％ of the overall malignant cancers. The top 10 death malignancies of the whole county was followed by lung cancer, liver cancer, gastric cancer, esophageal cancer, Hodgkin disease, leukemia, colorectal cancer, bone cancer, brain tumor and pancreatic cancer, accounting for 87.45 ％ of the overall malignant cancers. Conclusion Lung cancer ranks first in the incidence and mortality of malignant tumors of Shouyang County, Shanxi Province, and the prevention and control of major tumors should be strengthened.
ABSTRACT
Objective@#To determine the early recognizable factors related to patients with fulminant myocarditis.@*Methods@#Medical records from 60 adult patients who were diagnosed with acute viral myocarditis from January 2003 to September 2016 in our hospital were retrospectively reviewed, and divided into the fulminant group (n=9) and the non-fulminant group (n=51). Clinical presentations, biochemical markers, electrocardiography and echocardiography features on admission were analyzed.@*Results@#Prevalence of syncope (33.3%(3/9) vs. 2.0% (1/51), P=0.009) and fatigue (77.8% (7/9) vs. 21.6% (11/51) , P=0.002) was significantly higher, while the duration from flu-like syndromes to chest discomfort was shorter ((2.0±1.8) days vs. (4.5±3.5) days, P=0.041) in the fulminant group than that in the non-fulminant group. Systolic blood pressare (SBP) ((94±14) mmHg(1 mmHg=0.133 kPa) vs. (117±12)mmHg, P=0.001) and left ventricular ejection fraction((49±12)% vs. (60±13)%, P=0.016) were significantly lower, while heart rate ((99±20)bpm vs. (84±19)bpm, P=0.040) and NT-proBNP concentration ((7 962 (1 470, 23 849) ng/L vs. 1 771 (45, 2 380) ng/L, P=0.000) were significantly higher in the fulminant group than those in the non-fulminant group. PR interval was longer (199 (140, 416) ms vs. 156 (112, 204) ms, P=0.021), QRS complex was wider ((127±14)ms vs. (95±13)ms, t=-6.647, P<0.001) in the fulminant group than those in the non-fulminant group. Prolonged QRS duration≥120 ms was more often in fulminant group (77.8%(7/9) vs. 5.9%(3/51), P=0.000). Multivariate analysis revealed that PR interval (adjusted odd ratio 1.044, 95%CI 1.005-1.084, P=0.025) and QRS complex width (adjusted odd ratio 1.252, 95%CI 1.045-1.501, P=0.015) were the independent risk factors significantly associated with fulminant myocarditis.@*Conclusions@#The risk of a fulminant course of acute myocarditis is higher in patients with elevated NT-proBNP, reduced left ventricular ejection fraction, and conduction disturbances at admission. Prolonged PR interval and widened QRS complex on admission are independent risk factors for developing fulminant myocarditis in adult patients with acute viral myocarditis.

Objective Arenavirus is a negative single-stranded RNA virus and an important human pathogen,mainly harbored and transmitted by rodents,causing severe diseases,including hemorrhagic fever and encephalitis.Following the discovery of a novel pathogenic arenavirus (Wenzhou virus,WENV),the prevalence of WENV in local small rodents was investigated.Methods By using RT-PCR,WENV was screened in 48 and 156 rodents sampled from Wenzhou and Longquan,respectively.Results Consequently,WENV was detected in 5 (10.41％) rodents sampled from Wenzhou.However,no WENV was identified in all the rodents sampled from Longquan.Genetic analysis of complete genome sequences indicated that 4 of 5 virus strains were closely related to the known Wenzhou viruses with high homology.Especially,the L and S segments of Wencheng-Rn-288 strain shared homology of 87.5％ and 91.6％ with other viruses,respectively.They formed a distinct lineage,suggesting that this strain might be a novel variant of WENV.Conclusions Our results indicate that WENV has a high prevalence and high genetic diversity among rodents in Wenzhou.As the respiratory disease caused by WENV has been detected in Cambodia,it is necessary to strengthen the surveillance for WENV in China.

ABSTRACT
OBJECTIVE:To study the inhibition effects of tranilast on hypertrophic scar tissue of rabbits and its mechanism. METHODS:Rabbits were selected to induce hypertrophic scar(HS)model,the HS model rats were randomly divided into model control group (normal saline),tranilast low-dose,medium-dose,high-dose groups (0.3,0.5,0.7 mg/kg),6 rabbits in each group,local intradermaly injected corresponding drugs. Scar thickness 1 h before injection and the first,third,fifth week after in-jection in each group were measured,pathological changes of scar(fifth week after injection)were observed,transforming growth factor β1 (TGF-β1),α-smooth muscle actin(α-SMA)mRNA and protein expression were detected. RESULTS:Compared with 1 h before injection,scar thickness of rabbits in other groups were decreased after injection except for model control group. In fifth week after injection,compared with model control group,scar thickness of rabbits in other groups were decreased,pathological changes were improved;TGF-β1,α-SMA mRNA and protein expression were decreased (P<0.05),showing positive correlation with tranilast dose. CONCLUSIONS:Tranilast can inhibit the formation of hypertrophic scar,and the mechanism may be related to inhibiting the TGF-β1,α-SMA mRNA and protein expression.
ABSTRACT
Objective To evaluate the diagnostic accuracy and efficacy on cervical precancerous lesions and cervical cancer by HPV 16/18 E6 protein detection. Methods A total of 439 females with sexual activities were selected from Department of Gynaecology in Shanxi Cancer Hospital from May 2014 to January 2015, including 299 cases of cervical intraepithelial neoplasia (CIN)Ⅱ, CINⅢ or cervical cancer (the case group), and the other 140 cases (the control group). All the patients accepted the thinprep cytology test (TCT), HPV DNA and HPV 16/18 E6 oncoprotein tests and colposcope examination. Results The positive rates of the TCT, HPV DNA, HPV 16/18 E6 oncoprotein in the case group were 97.0 % (290/299), 94.3 % (282/299) and 66.9 % (200/299), respectively, and those in the control group were 44.3 % (62/140), 21.4 % (30/140) and 2.9%(4/140), respectively, and there were significant differences between both groups (all P<0.05). The sensitivity and specificity of the HPV 16/18 E6 oncoprotein test in detecting CINⅡ and above were 66.9 %and 97.1 %, respectively, and both of HPV DNA test were 94.3 % and 78.6 %, respectively; The consistent rate between HPV 16/18 E6 and HPV DNA was 71.9 % (κ= 0.21). In the case group, when TCT was associated with HPV DNA test, the sensitivity, specificity and accuracy were 98.9%, 82.8%and 81.7%, respectively, and when TCT was combined with HPV 16/18 E6 oncoprotein test, those were up to 97.9 %, 97.1 % and 95.0 %. Conclusion HPV 16/18 E6 oncoprotein test can improve the specificity of cervical cancer screening, so it may be used as a primary screening method in the less developed areas where HPV DNA test is difficult to be carried out, or as a shunt method for HPV DNA positive patients, which will allocate the limited health resources rationally.
ABSTRACT
Objective To develop a scoring system to determine peptic ulcer risks and to evaluate its screening efficiency.Methods A total of 862 people who underwent gastroscopy for the first time ranging from 18 to 45 years old were enrolled in this study.They were divided into two cohorts with the method of simple random sampling,514 in the original cohort and 348 in the validation cohort.Information such as demographic characteristics,dietary intake,lifestyle,symptoms relating to peptic ulcer was obtained.A multivariable logistic regression method was used to determine independent predictors of peptic ulcer.Based on the logistic regression model,a scoring system was developed with a regression coefficient-based scoring method.Then the scoring system was internally and externally validated.Each value of calibration,discrimination and accuracy were computed and then compared with those of original cohort to assess its screening efficiency.Results Three variables (gender,smoking and melena) composed the scoring system with scores ranging from 0 to 4 points.It had good calibration (P =0.956) and discrimination (area under the ROC =0.70,95％CI:0.65-0.76).With 2.5 points as the screening cutoff value,the sensitivity,specificity,accuracy rate,positive predictive value,negative predictive value,positive likelihood ratio and negative likelihood ratio were 49.5％,82.2％,75.5％,41.6％,86.4％,2.78 and 0.61,respectively.In the validation cohort,the sensitivity,specificity,accuracy rate,positive predictive value,negative predictive value,positive likelihood ratio and negative likelihood ratio were 27.2％,92.7％,71.3％,64.6％,72.3％,3.89 and 0.79.The results above indicated that the screening efficiency of the scoring system in the original cohort was similar to that in the validation cohort.Conclusion The scoring system to determine peptic ulcer risks,containing gender,smoking and melena,has good screening efficiency and can be applied to predict the risks of peptic ulcer.
ABSTRACT
Objective To explore the cancer incidence in registration areas in Shanxi Province. Methods Data of 8 cancer registration areas in 2011 were taken into account and cancer incidence in different areas with different ages was compared with that in other domestic areas. Results 8 395 new cases in Shanxi all cancer sites were reported in 2011, including 4 810 male and 3 585 female. The incidence of malignant cancer of Shanxi was 207.53/100 000, and the standardized incidence of Chinese population and world population were 125.20/100 000 and 165.72/100 000, respectively. In urban areas, the incidence of Shanxi and the standardized incidence of Chinese population were 202.49/100 000 and 112.81/100 000, respectively. In rural areas, incidence rate of Shanxi was 211.96/100 000 and the standardized incidence of Chinese population was 138.43/100 000. In Shanxi Province, the major malignant cancer sites for males involved stomach, lung, esophagus, liver and colorectum, and cancer sites for females were more on cervix, lung, breast, stomach and esophagus. Conclusions Upper gastrointestinal cancer and uterine cervix cancer are the major cancers in Shanxi registration areas. The incidence of stomach cancer and uterine cervix cancer in Shanxi Province are much higher than national average.
