Objective:To explore the mediating effect of self-management efficacy between social support and self-management behavior in cancer patients treated with proton-heavy ions.Methods:From April 2020 to April 2021, convenience sampling was used to select 674 cancer patients in Shanghai Proton and Heavy Ion Center as the research subject. The patients were investigated with the General Information Questionnaire, Chronic Disease Self-Management Study Measures (CDSMS) , Chinese-version Strategies Used by People to Promote Health (C-SUPPH) , and Medical Outcome Study Social Support Survey (MOS-SSS) . Statistical analysis was performed using SPSS 24.0 and AMOS 24.0 software. Pearson correlation was used to calculate the correlation between variables, and a structural equation model was constructed to test the relationship between variables. A total of 674 questionnaires were distributed, 610 valid questionnaires were recovered, and the valid recovery rate was 90.5% (610/674) .Results:The total scores of self-management behavior, self-management efficacy, and social support in 610 cancer patients treated with proton heavy ions were (18.38±7.64) , (94.30±22.72) and (73.97±13.94) , respectively. Pearson correlation analysis showed that except for the dimension of life support with dimension of exercise, all the other dimension scores and the total score of patients' social support were positively correlated with all the dimension scores and the total score of self-management behaviors ( P<0.05) ; the dimension scores and the total score of patients' social support were positively correlated with the dimension scores and the total score of self-management efficacy ( P<0.05) ; the dimension scores and the total score of patients' self-management efficacy were positively correlated with the dimension scores and the total score of self-management behavior ( P<0.05) . Self-management efficacy had a partial mediating effect between social support and medical staff communication behavior, with an effect value of 23.4% ( P<0.05) . Conclusions:Cancer patients treated with proton-heavy ions have poor levels of self-management behavior. Nurses can improve the patients' self-efficacy and enhance the impact of social support on the patients' self-management behavior, so as to promote the precise realization and timely completion of proton heavy ion therapy.

Objective:To evaluate the benefits and risks of advanced age patients with acute anterior circulation large vessel occlusive stroke (ALVOS) accepted mechanical thrombectomy (MT), and explore the related influencing factors for prognoses in these patients.Methods:Six hundred and eighty patients with acute anterior circulation ALVOS accepted MT in 3 comprehensive stroke centers from January 2014 to December 2020 were sequentially collected. (1) Patients were divided into advanced age group (≥80 years old) and non-advanced age group (<80 years old) according to age, and the differences between the two groups were compared in successful postoperative vascular recanalization rate, incidence of perioperative complications, and good prognosis rate (modified Rankin scale [mRS] scores≤2) and mortality 90 d after onset. (2) Patients were divided into good prognosis group (mRS scores≤2) and poor prognosis group (mRS scores>2) according to the prognoses 90 d after onset; univariate analysis and multivariate Logistic regression analysis were used to investigate the independent factors for prognoses of the patients after MT. (3) According to the prognoses 90 d after onset, the advanced age patients were divided into good prognosis subgroup (mRS scores≤2) and poor prognosis subgroup (mRS scores>2). Univariate analysis and multivariate Logistic regression analysis were used to investigate the independent factors for prognoses of the elderly patients after MT.Results:(1) In these 680 patients, 92 patients (13.5%) were into the advanced age group and 588 patients (86.5%) were in the non-advanced age group; patients in the advanced age group had significantly lower successful recanalization rate (67.4% vs. 77.9%), significantly lower good prognosis rate 90 d after onset (20.7% vs. 50.2%), and statically higher mortality 90 d after onset (40.2% vs. 21.1%) as compared with the non-advanced age group ( P<0.05); however, there was no significant difference between the two groups in the incidences of symptomatic intracranial hemorrhage (sICH, 15.6% vs. 10.6%) and malignant cerebral edema (MCE, 12.2% vs. 17.6%, P>0.05). The baseline data of the advanced age and non-advanced age patients were further matched with propensity score matching analysis (1:1) and statistically analyzed: the 91 elderly patients had significantly lower good prognosis rate 90 d after onset (20.9% vs. 36.3%) and MCE incidence (12.4% vs. 33.3%) than the 91 non-elderly patients ( P<0.05); there was no significant differences in successful vascular recanalization rate (67.0% vs. 71.4%), sICH incidence (15.7% vs. 17.6%) or mortality 90 d after onset (39.6% vs. 37.4%) between the two groups ( P>0.05). (2) Among the 680 patients, 314 (46.2%) had good prognosis and 366 (53.8%) had poor prognosis. As compared with the good prognosis group, the poor prognosis group had significantly higher proportion of patients at advanced age, significantly lower proportion of male patients, significantly higher proportion of patients with hypertension, diabetes or atrial fibrillation, significantly lower baseline Alberta Stroke early CT (ASPECT) scores, significantly higher baseline National Institutes of Health Stroke Scale (NIHSS) scores, statistically higher proportion of patients with cardiogenic embolism, significantly lower incidence of tandem lesions, significantly shorter time from onset to sheathing, statistically higher proportion of internal carotid artery occlusion, significantly lower proportion of patients with grading 2 collateral circulation, and significantly lower proportion of successful vascular recanalization ( P<0.05). Advanced age ( OR=3.144, 95%CI: 1.675-5.900, P<0.001) was an independent factor for prognoses 90 d after MT, in addition to baseline ASPECT scores, baseline NIHSS scores, diabetes mellitus, successful recanalization, and collateral circulation grading. (3) In the advanced age group, there were 19 patients (20.7%) with good prognosis and 73 patients (79.3%) with poor prognosis. As compared with the good prognosis subgroup, the poor prognosis subgroup had significantly lower proportion of male patients, significantly lower proportion of patients with grading 2 collateral circulation or complete recanalization, and significantly higher baseline NIHSS scores ( P<0.05). Baseline NIHSS score ( OR=1.482, 95%CI: 1.187-1.850, P=0.001) was an independent factor for prognoses 90 d after MT in advanced age patients. Conclusion:Although advanced age is an independent risk factor for prognoses of patients with acute anterior circulation ALVOS accepted MT, there are still some advanced age patients benefiting from MT without increased complications, especially for those with low baseline NIHSS scores.

Objective:To study the efficacy and influencing factors of ursodeoxycholic acid (UDCA) in the treatment of cholesterol gallstone, so as to provide reference for the treatment of cholesterol gallstone by internal medicine.Methods:From March 1, 2017 to March 31, 2018, at outpatient department of gastroenterology of 9 Beijing medical centers including Peking University People′s Hospital, the Sixth Medical Center of PLA General Hospital, Beijing Huaxin Hospital, PLA Rocket Force Characteristic Medical Center, Peking University Aerospace Center Hospital, Beijing Youan Hospital of Capital Medical University and Beijing Tiantan Hospital of Capital Medical University, Beijing Tongren Hospital of Capital Medical University, and Beijing Shijitan Hospital of Capital Medical University, the data of patients with cholesterol gallstone treated by UDCA were collected. The inclusion criteria were that the largest diameter of stone was ≤10 mm and the stone was not detected under X-ray. The treatment plan was taking UDCA orally for 6 months at a dose of 10 mg·kg -1·d -1. The basic information of patients, the ultrasound examination results before treatment and 6 months after treatment, and scores of biliary abdominal pain and dyspepsia symptom were collected. Univariate and multivariate logistic regression were used to analyze the influencing factors of the efficacy in gallstrone dissolution by UDCA, and Wilcoxon signed rank test was used for statistical analysis. Results:A total of 215 patients were enrolled. The complete dissolution rate of gallstone was 19.5% (42/215) and partial dissolution rate was 50.7% (109/215), and the total effective rate was 70.2% (151/215). The complete dissolution rate of sandy stone was significantly higher than that of lumped stones (37.0%(17/46) vs. 14.8%(25/169); OR=3.377, 95% confidence interval (95% CI) 1.621 to 7.035, P=0.001). In lumped stones, the complete dissolution rate of the stones with diameter ≤5 mm was significantly higher than that of the stones with diameter >5 mm (37.5%(9/24) vs. 11.0%(16/145); OR=4.837, 95% CI 1.823 to 12.839, P=0.002). The complete dissolution rate of patients with higher body mass index ( OR=0.872, 95% CI 0.764 to 0.995, P=0.043) and longer disease course ( OR=0.942, 95% CI 0.912 to 0.973, P<0.001) was low. The results of multivariate logistic analysis indicated that long disease course of gallstone ( OR=0.940, 95% CI 0.908 to 0.974, P=0.001), rough gallbladder wall ( OR=0.438, 95% CI 0.200 to 0.962, P=0.040) and lumped stone ( OR=0.236, 95% CI 0.101 to 0.550, P=0.001) were independent risk factors of influencing the efficacy of stone dissolution by UDCA. As for lumped stones, the independent risk factors included long disease course of gallstone ( OR=0.926, 95% CI 0.877 to 0.978, P=0.006) and stone diameter >5 mm ( OR=0.142, 95% CI 0.043 to 0.470, P=0.001). After 6 months of UDCA treatment, score of biliary abdominal pain decreased from 0 (0 to 6) to 0 (0 to 0) and the score of dyspepsia symptom decreased from 1 (0 to 2) to 0 (0 to 0), and the differences between before treatment and after treatment were statistically significant ( Z=-8.50, and -9.13, both P<0.001). Conclusions:UDCA has a certain efficacy in cholesterol gallstone dissolution and can ease biliary abdominal pain and dyspepsia symptom. Long disease course of gallstone, rough gallbladder wall and stone diameter >5 mm are independent risk factors of poor efficacy in gallstone dissolution by UDCA.

Objective: To investigate the current awareness of core knowledge about cancer prevention and its influencing factors among residents in Zhejiang Province, in order to provide a reference for formulating provincial health education strategies of cancer prevention. Methods : From November 2019 to October 2020, the permanent residents aged 18-74 years in Zhejiang Province were selected using multi-stage stratified sampling method. A questionnaire was designed according to Core Information and Knowledge on Cancer Prevention to collect general information, health status, and awareness of core knowledge about cancer prevention. The multivariate logistic regression model was used to analyze the influencing factors. Results: Among 6 974 valid respondents, 3 139 ( 45.01% ) were males and 3 835 ( 54.99% ) were females. The overall awareness rate of core knowledge about cancer prevention was 74.66%; the awareness rates of basic knowledge, risk factors and primary prevention, screening and early diagnosis as well as treatment and rehabilitation were 79.08%, 80.83%, 76.08% and 82.99%, respectively. The multivariate logistic regression analysis showed that the residents who were in rural areas ( OR=0.659, 95%CI: 0.585-0.743 ), ≥45 years old ( OR: 0.794-0.801, 95%CI: 0.655-0.981 ) and with obesity (OR=0.531, 95%CI: 0.436-0.647) had lower awareness rates, while the residents who were with an educational level of junior high school/technical school/senior high school or above ( OR: 1.390-4.361, 95%CI: 1.208-5.600 ), married (OR=1.414, 95%CI: 1.142-1.752), administrative/technical personnel ( OR=2.602, 95%CI: 2.005-3.377 ), service staff/private business owners ( OR=1.368, 95%CI: 1.111-1.684), retired ( OR=1.345, 95%CI: 1.105-1.639 ) and others ( OR=1.542, 95%CI: 1.295-1.838 ), and with experience of cancer screening or examination ( OR=1.267, 95%CI: 1.123-1.428 ) had higher awareness rates. Conclusions The awareness rate of core knowledge about cancer prevention in Zhejiang Province is 74.66%. Health education for the residents aged ≥45 years, living in rural areas, having low educational levels, and having obesity should be

Colorectal cancer is a significant public health issue all over the world. Screening has been shown effective in improving the survival rate and decreasing the deaths of colorectal cancer. Several organizations have released guidelines for colorectal cancer screening. However, detailed recommendations like the age to begin remain controversial. This paper summarizes the recommended different age groups in initiating the colorectal cancer screening program from a few guidelines and analyzes the reasons for the inconsistency, thus facilitating the drafting of colorectal cancer screening guidelines in China.

Objective:To analyze the results of liver cancer screening for urban residents in Zhejiang Province from 2013 to 2018 and explore the influencing factors of the detection rate.Methods:From September 2013 to August 2019, six urban communities in Hangzhou (Jianggan District and Gongshu District), Ningbo (Haishu District, Yinzhou District and Jiangbei District), and Quzhou (Kecheng District) were selected as study sites. All permanent residents aged 40-74 (with local household registration and living in the local area for more than 3 years) were selected as the research subjects by using cluster sampling method. Patients with confirmed cancers and other serious medical and surgical diseases were excluded. A total of 166 293 research subjects were included. Basic demographic characteristics and risk factors of subjects were obtained through questionnaire surveys. The cancer risk assessment system was used to evaluate the liver cancer risk of subjects. Clinical screening participation and screening results for subjects at high risk of liver cancer were obtained from participating hospitals. The high-risk rate of liver cancer, clinical screening rate, detection rate of positive lesions, and detection rate of suspected liver cancer were analyzed. Poisson regression was used to analyze the influencing factors of detection rate.Results:The age of 166 293 subjects was (56.01±8.40) years, of which 41.36% (68 777) were males. A total of 23 765 high-risk subjects for liver cancer were screened (the high-risk rate was 14.29%). Among them, a total of 12 375 subjects participated in clinical screening for liver cancer, with a screening rate of 52.07% (12 375/23 765). A total of 297 cases of positive lesions were detected and the detection rate was 2.40% (297/12 375). A total of 8 cases of suspected liver cancer were detected, with a detection rate of 0.06% (8/12 375). The results of multivariate Poisson regression model analysis showed that compared with men, people who never smoked, never ate pickled food, had low oil content, and had no history of hepatobiliary disease, female, people who were smoking or had smoked, sometimes ate pickled food, ate higher oil content, and had a history of hepatobiliary disease had a higher detection rate of positive lesions. The incidence rate ratio (IRR) ( 95%CI) values were 1.98 (1.45-2.70), 2.23 (1.61-3.09)/2.08 (1.31-3.28), 1.82 (1.22-2.70), 1.44 (1.08-1.91), and 1.45 (1.05-2.00), respectively. Compared with those aged from 40 to 49 years old and without HBsAg test, the IRR (95% CI) of suspected liver cancer in people aged 70 to 74 years old and HBsAg positive were 16.30 (1.32-200.74) and 6.43 (1.24-33.22), respectively. Conclusion:The urban cancer early diagnosis and early treatment project in Zhejiang Province has good compliance in clinical screening of liver cancer. Abdominal ultrasound examination and serum alpha-fetoprotein detection are helpful to detect liver cancer and its precancerous lesions in the high-risk population of liver cancer.

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.
