Objective:The establish a standardized training assessment indicator system for young teachers in medical colleges and universities, and to improve the quality of training.Methods:A preliminary assessment indicator system was established through literature analysis and small-sample expert interviews, and then the Delphi method was used to conduct consultation with 40 experts familiar with the standardized training of young teachers in medical colleges and universities. The assessment indicator system was modified based on the opinions of the experts, and consultation was conducted again until basically consistent opinions were obtained from the experts. The analytic hierarchy process was used to assign weights to each indicator, and SPSS 17.0 was used for data analysis and processing.Results:After two rounds of expert consultation, 35 experts agreed with each indicator at a rate of more than 90%, and their opinions were basically consistent. The weight variation coefficient (W value) of each indicator ranged from 0.00 to 0.15, indicating a high degree of concentration. Finally, a standardized training assessment indicator system was established for young teachers, which consisted of 4 first-level indicators, 11 second-level indicators, and 35 third-level indicators.Conclusions:This assessment indicator system provides a basis for scientific evaluation of the quality of standardized training for young teachers in medical colleges and universities and improves the quality and efficiency of standardized training for young teachers by "promoting construction through evaluation and promoting supervision through evaluation".

OBJECTIVE：To investigate the effects of rabepr azole on the pharmacokinetic characteristics of clopidogrel and its active metabolite in healthy volunteers with different CYP2C19 genotypes. METHODS ：Healthy volunteers were selected as subjects，and then randomly divided into extensive metabolizer （EM）group，intermediate metabolizer （IM）group，and poor metabolizer（PM）group with 8 subjects in each group ，according to their CYP2C19 genotypes by random number table. In single-dose，randomized，open，two-cycle-crossover design ，each group was given Clopidogrel bisulfate tablets 300 mg or Clopidogrel bisulfate tablets 300 mg+Rabeprazole sodium enteric-coated tablets 20 mg. UPLC-MS/MS method was adopted to detect the concentration of clopidogrel and its active metabolite derivative （MP-H4）. The pharmacokinetic parameters were calculated and compared by DAS 2.0 software. RESULTS ：There was no statistical significance in clinical data as age ，height， body weight ，liver enzymes and serum creatinine among 3 kinds of metabolism subjects （P＞0.05）. Compared with subjects receiving clopidogrel alone ，cmax and AUC 0－t of clopidogrel of subjects combined with rabeprazole in EM group were increased by 36％ and 27％，while those of MP-H 4 were decreased by 34％ and 28％（P＜0.01）；cmax and AUC 0－t of clopidogrel of subjects combined with rabeprazole in IM group were increased by 19％ and 18％，while those of MP-H 4 were decreased by 19％ and 16％ （P＜0.05 or P＜0.01）；there was no statistical significance in cmax and AUC 0－t of clopidogrel and MP-H 4 in PM group after receiving rabeprazole additionally as well as tmax of clopidogrel and MP-H 4 in all metablism subjects ，compared with clopidogrel alone（P＞0.05）. CONCLUSIONS ：Among CYP2C19 EM and IM subjects ，combined use of rabeprazole can significantly increase the exposure of clopidogrel and decrease the exposure of its active metabolite MP-H 4，but has no significant impact on clopidogrel and its active metabolite in CYP2C19 PM subjects.

Cholangiocarcinoma is the most common malignant tumor of the biliary tract, with a relatively high mortality rate and an incidence rate increasing year by year. Due to atypical symptoms in the early stage and complex anatomical location, it is often difficult for patients with cholangiocarcinoma to be diagnosed in the early stage, and therefore, they often miss the optimal treatment period and tend to have poor prognosis. In recent years, studies have shown that miRNAs play a key role in the pathophysiological process of the development and progression of cholangiocarcinoma. This article reviews the regulatory role of miRNAs in the development, invasion, metastasis, drug resistance, and tumor microenvironment of cholangiocarcinoma and introduces the latest advances in exosome miRNA and cholangiocarcinoma, so as to provide potential treatment strategies for cholangiocarcinoma.

Objective: To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents 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 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.

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.

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.

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.

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.

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.

Objective To compare the efficacy of endoscopic sphincterotomy ( EST) combined with large-balloon dilation ( LBD) and that of LBD alone for large bile duct stones. Methods Data of 61 patients who received EST combined with LBD ( the combination group ) and 48 patients who received LBD alone ( the LBD group) from February 2008 to November 2014 were collected. The efficacy and adverse events of two groups were compared. Results The procedure time from successful cannulating to complete stone removal was shorter in the LBD group than that in the combination group [ 17. 3 min ( 8-35 min ) VS 21. 5 min ( 10-42 min) , P=0. 041] . There were no significant differences in overall complete stone removal rate[90. 2％ (55/61) VS 91. 7％ (44/48), P=1. 000] and complete stone removal rate without mechanical lithotripsy[78. 7％ (48/61) VS 83. 3％ (40/48), P=0. 542] in the combination group and the LBD group. Massive bleeding occurred in one patient of the combination group, but was successfully coagulated under endoscopy. There was no significant difference in the incidence of postoperative pancreatitis between the two groups[4. 9％ (3/61) VS 6. 3％ (3/48), P=1. 000]. Conclusion EST combined with LBD offers no significant advantage over LBD alone for the removal of large bile duct stones. LBD can simplify the procedure compared with EST combined with LBD in terms of shortening the procedure time.
