Extended circulation of anticancer nanodrugs in blood stream is essential for their clinical applications. However, administered nanoparticles are rapidly sequestered and cleared by cells of the mononuclear phagocyte system (MPS). In this study, we developed a biomimetic nanosystem that is able to efficiently escape MPS and target tumor tissues. The fabricated nanoparticles (TM-CQ/NPs) were coated with fibroblast cell membrane expressing tumor necrosis factor (TNF)-related apoptosis inducing ligand (TRAIL). Coating with this functionalized membrane reduced the endocytosis of nanoparticles by macrophages, but increased the nanoparticle uptake in tumor cells. Importantly, this membrane coating specifically induced tumor cell apoptosis via the interaction of TRAIL and its cognate death receptors. Meanwhile, the encapsulated chloroquine (CQ) further suppressed the uptake of nanoparticles by macrophages, and synergized with TRAIL to induce tumor cell apoptosis. The vigorous antitumor efficacy in two mice tumor models confirmed our nanosystem was an effective approach to address the MPS challenge for cancer therapy. Together, our TM-CQ/NPs nanosystem provides a feasible approach to precisely target tumor tissues and improve anticancer efficacy.

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 investigate the early predictive factors of periprocedural thrombus migration and the relationship between periprocedural thrombus migration and prognosis after mechanical thrombectomy (MT) in stroke patients.Methods:The patients with anterior circulation acute large vessel occlusion stroke (ALVOS) who underwent MT in the Stroke Center of Yijishan Hospital of Wannan Medical College from May 2015 to December 2019 were retrospectively analyzed. The baseline characteristics, procedural and clinical outcomes were collected. Univariate and multivariate regression analysis was used to explore the risk factors of thrombus migration and the relationship between thrombus migration and prognosis of patients.Results:There were 302 ALVOS patients [(68.8±11.0) years old and 166 males (55.0%)] included, of whom thrombus migration was identified in 80 patients (26.5%), including 60 cases (75.0%) of proximal migration. Cardiogenic stroke ( OR=2.722, 95% CI 1.367-5.418, P=0.004) and clot burden score (CBS; OR=0.849, 95% CI 0.745-0.968, P=0.015) were independent risk factors of thrombus migration. Proximal migration ( OR=2.822, 95% CI 1.220-6.528, P=0.015) was an independent risk factor of 90-day clinical outcome, while the effect of distal migration on 90-day clinical outcome was not statistically significant. Conclusions:Cardiogenic stroke and lower CBS score are independent predictors of periprocedural thrombus migration in ALVOS patients who underwent MT. Proximal migration is an independent risk factor for the prognosis of patients, which has important clinical intervention significance.

Objective:To construct a scientific and practical micro-course content framework of cross-cultural nursing hospice care from the perspective of attention, relevance, confidence and satisfaction (ARCS) model.Methods:The research team was established in November 2018. Using Delphi method, 16 experts in cross-cultural nursing, hospice care, nursing management, nursing education and other fields were consulted for 3 rounds of correspondence. According to scores of experts, the index weights were calculated to form micro-course content framework of cross-cultural nursing hospice care from the perspective of ARCS model.Results:The positive coefficient of experts surveyed by the questionnaire was 100%, the average value of expert authority coefficient was 0.81. The determined importance values of the first and second level indexes were all greater than 4.00. The coefficient of variation was 0 to 0.12, which were all less than 0.25 and met the requirements. In the end, a content framework containing 3 first-level indexes of professional concepts, professional knowledge and professional skills and 19 second-level micro-course content framework of cross-cultural nursing hospice care were formed.Conclusions:Based on the perspective of ARCS model, the construction process of content framework of the cross-cultural nursing hospice care micro-course is scientific and the setting is reasonable, which has a good guiding significance for the development of training for hospice care nurses.

Objective:To construct a cross-cultural nursing quality sensitive indicator system, so as to provide a basis for the hospital's cross-cultural nursing quality evaluation and monitoring.Methods:Based on the Donabedian model and the sunrise model, this study adopted the literature analysis method and the research team discussed preliminary screening indicators. From May to June 2020, 15 nursing and medical experts from a university hospital in Shanghai were selected as the subject of the consultation by using the method of convenience sampling. The Delphi method was used to conduct two rounds of expert consultations to determine the content of sensitive indicators of cross-cultural nursing quality.Results:The positive coefficients of the two rounds of consultations were 100%, and the authority coefficients were 0.883 and 0.893. The constructed cross-cultural nursing quality sensitive indicators included 3 first-level indicators and 20 second-level indicators.Conclusions:The cross-cultural nursing quality sensitive indicator constructed based on the Delphi method is scientific and representative, which can provide a reference for nursing quality evaluation and continuous quality improvement evaluation.

Objective:To explore the influence of blood pressure (BP) profiles 24 h after early endovascular treatment (EVT), including mean blood pressure and blood pressure variability, in clinical prognoses of patients with acute large vessel occlusion stroke (ALVOS) of anterior circulation 90 d after EVT.Methods:Clinical data and blood pressure profiles of patients with ALVOS of anterior circulation who received EVT in our hospital from July 2014 to February 2019 were prospectively collected. The 90-d modified Rankin scale (mRS) scores were used as clinical prognosis evaluation, and modified thrombdysis in cerebral infarction (mTICI) was used as evaluation criteria for recanalization of postoperative occlusive blood vessels. Multivariate Logistic regression analysis was used to determine the independent influencing factors for prognoses 90 d after EVT.Results:(1) Two hundred and sixteen patients were collected; 159 patients were with successful recanalization and 57 patients were with unsuccessful recanalization; 90 d after EVT, 95 patients (44%) had good prognosis and 121 patients (56%) had poor prognosis. As compared with patients in the good prognosis group, patients in the poor prognosis group had signficantly advanced age, signficantly higher proportion of patients with atrial fibrillation, signficantly higher baseline NIHSS scores, and signficantly lower baseline ASPECT scores ( P<0.05); and the differences of occlusion locus were statistically significant between patients from the good and poor prognosis groups ( P<0.05). Patients in the poor prognosis group had significantly higher baseline systolic blood pressure (SBP), mean SBP, max SBP, and significantly higher standard deviation, variable coefficient, and continuous variation of SBP, and statistically higher standard deviation, variable coefficient, and continuous variation of diastolic blood pressure (DBP) as compared with those in the good prognosis group ( P<0.05). Multivariable Logistic regression analysis showed that the standard deviation and continuous variation of SBP were independent influencing factors for clinical prognoses 90 d after EVT ( OR=1.116, 95%CI: 1.002-1.243, P=0.047; OR=1.116, 95%CI: 1.016-1.227, P=0.022). (2) In patients with successful recanalization, as compared with patients in the good prognosis subgroup, patients in the poor prognosis subgroup had signficantly advanced age, statistically higher proportions of patients with diabetes mellitus and atrial fibrillation and baseline NIHSS scores, and statistically lower baseline ASPECT scores ( P<0.05); and the differences of occlusion locus and first choices of treatment were statistically significant between patients in the good and poor prognosis subgroups ( P<0.05). Patients in the poor prognosis subgroup had significantly higher baseline SBP and max SBP, and significantly higher standard deviation, variable coefficient, and continuous variation of SBP, and statistically higher variable coefficient of DBP as compared with those in the good prognosis subgroup ( P<0.05). Multivariable Logistic regression analysis showed the standard deviation, variable coefficient, and continuous variation of SBP were independent influencing factors for clinical prognoses 90 d after EVT ( OR=1.164, 95%CI: 1.021-1.326, P=0.023; OR=1.191, 95%CI: 1.007-1.409, P=0.041; OR=1.141, 95%CI: 1.018-1.279, P=0.024). However, in patients with unsuccessful recanalization, there were no significant differences in blood pressure proliles between the good prognosis subgroup and poor prognosis subgroup ( P>0.05). Conclusion:The blood pressure variability 24 h after EVT is correlated with the clinical prognoses of patients with ALVOS of anterior circulation 90 d after EVT.

Objective:To analyze the results and cost-effectiveness of colorectal cancer (CRC) screening program among Zhejiang urban residents so as to provide evidence for further optimization of CRC screening strategies.Methods:Based on the Cancer Screening Program in Urban China which was conducted in Zhejiang province from 2013-2018, data related to the rates on compliance and detection through the CRC screening program among the 40-74 year-old residents were analyzed. Chi-square tests were used to compare the differences among groups, and multivariate logistic regression models were applied to explore the potential risk factors. Cost-effectiveness ratio (CER) was calculated by using the cost per lesion detected as the indicator.Results:Among all the 166 285 participants who completed the risk assessment questionnaire, 21 975 (13.2%) were recognized as under the high risk of CRC and 4 389 (20.0%) of them received the colonoscopy. The detection rates of CRC, advanced adenoma, and non-advance adenoma were 0.3% (11 cases), 2.7% (119 cases), and 5.2% (229 cases), respectively. Results from the multivariate logistic regression analyses showed that factors as age, gender, education level, smoking, drinking alcohol, previous fecal occult blood test (FOBT), polyp history, and family history of CRC were significantly associated with the compliance rate of colonoscopy while age, smoking and polyp history were significantly associated with the detection rate of advanced neoplasms (CRC and advanced adenoma). The costs were ￥22 355.74 Yuan for every CER advanced neoplasm detection and ￥264 204.18 Yuan per CRC detection, respectively. The CER decreased along with ageing. Sensitivity analysis showed that CERs were expected to decrease when the compliance rate of colonoscopy was increasing.Conclusions:The current screening program seems effective in detecting the precancerous colorectal lesions, but the relatively low compliance rate of colonoscopy restricting both the diagnostic yields and economic benefits. It is necessary to improve the awareness and acceptance of colonoscopy among the high-risk CRC population.

Objective:To observe the incidence, risk factors of malignant brain edema (MBE) and the influence of MBE on outcomes after early successful recanalization of acute large vascular occlusion stroke (ALVOS).Methods:A total of 149 patients (age (68±11) years, male 85 (57.0%)) with ALVOS who underwent early endovascular treatment and achieved successful recanalization at the First Affiliated Hospital of Wannan Medical College from July 2014 to February 2019 were retrospectively analyzed. Baseline data, perioperative data, and 90-day prognostic information were collected from patients enrolled in the study. Univariate and multivariate analyses were used to explore the relationship between MBE and outcomes, and the risk factors of MBE.Results:Among the 149 patients, baseline National Institutes of Health Stroke Scale score was 16 (13, 20), baseline Alberta Stroke Project early CT score was 9 (8, 10), the time of onset-to-puncture was (248.3±61.3) minutes, and the onset-to-recanalization time was (312.4±69.7) minutes. MBE occurred in 23 patients (15.4%, 23/149). The 90-day favorable outcome (90-day modified Rankin Scale score≤ 2) in patients with MBE was significantly lower than those without MBE (17.4% (4/23) vs 61.1% (77/126), χ 2=14.985, P<0.001), and the 90-day mortality in patients with MBE was significantly higher than those without MBE (43.5% (10/23) vs14.3% (18/126), χ 2=10.861, P=0.003). MBE was shown to be an independent predictor of 90-day poor outcome (adjusted OR=12.078, 95 %CI 1.934-75.443, P=0.008) and death (adjusted OR=4.146, 95 %CI 1.060-16.216, P=0.041). Multivariate Logistic regression analysis showed that the collateral circulation status was related to the incidence of MBE in patients with ALVOS after successful recanalization (level 2 vs level 0, adjusted OR=0.109, 95 %CI 0.021-0.563, P=0.008). Conclusions:MBE is an independent risk factor of ALVOS patients with poor outcome or death in 90 days. For patients with ALVOS, even if the occlusive vessels have been successfully recanalized after early endovascular treatment, MBE is still not uncommon. The collateral circulation state is an independent predictive factor of the development of MBE after recanalization by early endovascular treatment in patients with ALVOS.

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.
