Objective To explore the impact of a“one-week”staged multivessel percutaneous coronary intervention (PCI) versus culprit-only PCI on deaths and major adverse cardiac events (MACE). Methods We retrospectively analyzed 447 patients with multivessel disease who experienced a ST-segment elevation myocardial infarction (STEMI) within 12 h before undergoing PCI between July 26, 2008 and Septem-ber 25, 2011. After completion of PCI in the infarct artery, 201 patients still in the hospital agreed to undergo PCI in non-infarct arteries with more than 70%stenosis for a“one-week”staged multivessel PCI. A total of 246 patients only received intervention for the culprit vessel. Follow-up ended on September 9, 2014. This study examined the differences in deaths from any cause (i.e., cardiac and noncardiac) and MACE between the two treatment groups. Results Compared to a culprit-only PCI treatment approach, the“one-week”staged multivessel PCI was strongly associated with greater benefits for 55-month all cause death [41 (16.7%) vs.13 (6.5%), P=0.004] and MACE [82 (33.3%) vs. 40 (19.9%), P=0.002] rates. In addition, there were significant differences in the number of myocardial infarctions [43 (17.5%) vs. 20 (10.0%), P=0.023], coronary-artery bypass grafting [CABG;20 (8.1%) vs. 6 (3.0%), P=0.021], and PCI [31 (12.6%) vs. 12 (6.0%), P=0.018]. Patients undergoing culprit-only PCI compared to“one-week”PCI had the same number of stent thrombosis events [7 (2.8%) vs. 3 (1.5%), P=0.522]. Conclusions Compared to a culprit-only PCI treatment approach,“one-week”staged multi-vessel PCI was a safe and effective selection for STEMI and multi-vessel PCI.

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

OBJECTIVETo investigate the effect of epidermal stem cells from human hypertrophic scar (HS-ESCs) on the skin wound healing in nude mice.
METHODS40 mice were randomly divided into two groups as experimental group (n = 20) and control group (n = 20). Wounds, 1 cm in diameters, were made on every mouse back. The wounds were treated with HS-ESCs and erythromycin ointment in experimental group, or only with erythromycin ointment in control group. The wound healing was observed during the following 14 days. The expression of collagen-I, collagen-III, epidermal growth factor (EGF), fibroblast growth factor (FGF2) , transforming growth factor (TGFbeta1, and TGFbeta2) were studied.
RESULTSThe wound healing time in the experimental group was (20.8 +/- 0.84) d, which was (25.6 +/- 0.89) d in the control group. HE staining revealed that the extent of vascularization in the experimental group was 11.60 +/- 0.55, while it was 8.04 +/- 0.33 in the control group. Immunochemistry analysis showed the expression of collagen-I, collagen-III, EGF, FGF2, TGFbeta1, and TGFbeta2 in the experimental group were significantly higher, compared with those in control group (P < 0.05).
CONCLUSIONHS-ESCs may promote wound healing through enhancement of the vascularization of the wound tissue and the expression of growth factors.
