Globally, individuals with chronic diseases now consume over 80% of all healthcare resources. Set against this depressing projection is decades of epidemiologic work demonstrating that 80%-90% of cardiovascular disease can be prevented via lifestyle and dietary interventions. How can we reconcile such contrasting views toward the future of cardiovascular health in human populations? Herein, we review available sources of evidence that can be used to answer these challenging questions of how and why. In particular, we submit that analytical framework incorporating the 6P (prediction, precision, personalization, prevention, population, and policy)-3G (good food, good environment, and good behavior)-4I (interpretation, integration, implementation, and innovation) will allow us to focus resource towards the development of multi-level approaches for the betterment of population

Objective:To prepare nanobody-based immunotoxin BI7D12-PE38KDEL targeting EGFR and to examine its cytotoxicity against EGFR positive tumor cells.Methods:By using molecular cloning strategy,prokaryotic expression construct of pET28a-BI7D12-PE38KDEL was generated which consisted of nanobody 7D12 targeting EGFR in the form of a divalent fused with PE38KDEL,a truncated form of pseudomonas exotoxin A via a flexible peptide(G4S)4,and then transformed into E.coli BL21(DE3).Protein expression was induced by adding IPTG,purified by Ni-affinity column chromatography,and verified by Western blot.The binding capacity of the resulted immunotoxin to EGFR-positive cells A549,HT29,MCF-7 and EGFR-negative cells CEM,Jurkat were determined by flow cytometry assay,and its cytotoxicity against the target cells was examined.Briefly,tumor cells were treated with different dosage of the immunotoxin,and the killing efficacy of BI7D12-PE38KDEL on these cells were assessed by WST-1 assay after 72 hours.Results:The SDS-PAGE and Western blot results showed the recombinant immunotoxin BI7D12-PE38KDEL was successfully prepared,and majority of them was expressed in soluble form.BI7D12-PE38KDEL could selectively bind to EGFR-positive cells of A549,HT29,and MCF-7.More importantly,the immunotoxin exhibited much more significant killing effect on these EGFR positive cells compared to the negative control group of CEM and Jurkat cells(P<0.01).Conclusion:In the current study,the nanobody-based immunotoxin BI7D12-PE38KDEL targeting EGFR was successfully prepared and exhibited a superior inhibition effect for the growth of EGFR-positive cells.

AIM: To choose the anti myocardial ischemic ingredients from polysaccharide of Ophiopogon Japonicus(PO), then to confirm their effects. METHODS: According to molecular weight, PO was separated to three portions by using ultrafiltration technique. The effects of each separated portion on myocardial ischemia induced by isoproterenol were studied. Then the effects of PO active portions (POAP) on the convulsion of coronary artery induced by pituitrin and acute myocardial ischemia caused by the ligation of coronary artery were further studied in rats. RESULTS: POAP could resist the elevation of Tand S T phase induced by pituitrin in rats, remarkably decrease the elevated S T phase and contents of CK and LDH in serum caused by the ligation of rat coronary artery. POAP also exerted some inhibition effects on the reduction of SOD and increase of MDA caused by myocardial ischemia. CONCLUSION: POAP can protect myocardial cells, inhibit the generation of free radicals, and scavenge the oxygen free radicals generated from myocardial ischemia.

Objective To evaluate the correlation between seram interleukin-10 (IL-10) and testosterone with coronary heart disease (CHD). Methods 387 patients were divided into CHD group (n = 239) and control group ( n = 148 ) according to the results of coronary angiography. CHD patients were divided into subgroups accord-ing to the numbers, Gensini score of lesions in the coronary arteries and clinical severity ( statue of stable coronary artery disease, unstable angina or acute myocardial infarction). Serum IL-10 and testosterone levels were measured by ELASA. Logistic regression and partial correlation were used to evaluate the correlation of serum IL-10 and testoster-one with CHD. Results IL-10 was significantly lower in the CHD group than in the control group[ (39.08 ± 14.22) ng/L vs (49.27 ± 24.67)ng/L, P < 0. 001 ]. The partial correlation analysis results in subgroups showed that the correlation coefficient of IL-10 with number of lesions,gensini score and clinical severity of CHD was - 0.25, P < 0.001, -0.25 ,P <0.05 and -0.25 ,P <0.001 ,respectively. Serum testosterone had no difference in control group and CHD group (P >0.05 ). Logistic regression analysis found that only smoking (OR = 3.79,95% CI 2.09～ 6.84,P<0.01) ,diabetes mellitus (OR =2.48,95% CI 1.05 ～5.88,P <0. 05) ,apoB ( OR = 14.3,95% CI 4.29～46.61 ,P <0.01 ) and IL-10 ( OR =0.74,95%, CI 0.57～0.89 ,P <0.01 ) entered the model. Conclusions Serum IL-10 is not only significantly correlated with CHD but also with its severity. IL-10 is an independent pro-tective factor for CHD.

Medicinal animals are important part of Traditional Chinese medicine resources in China. Cytochrome c oxidase subunit I (COI) was selected as the standard DNA barcoding sequence for animal medical materials. In this study, the 51 animal species from 45 animal medical materials in the Chinese Pharmacopoeia were selected and the intra-specific variation and the inter-specific divergence, the barcoding gap, the identification efficiency of their COI sequences were analyzed. The results showed that the inter-specific divergence is higher than intra-specific distance. The barcoding gap existed between inter-specific sequence divergence and intra-specific dis-tance. The identification efficiencies were 100% both at the genus and species level except the Arthropoda. The cluster dendrogram exhibited that different species distinguished from others. Therefore, COI sequence as a bar-code is suitable to identify the species of animal medical materials in Chinese Pharmacopoeia.

Objective:To analyze the current situation of health education among medical staff at all levels of hospitals in Beijing, for references in improving the level of hospital health education.Methods:From July to November 2022, a stratified random sampling method was used to select medical staff from hospitals at all levels in Beijing as the survey subjects. A self-designed questionnaire was used to investigate the frequency of health education conducted by medical staff in six dimensions. The Likert 5-level scoring method was used to assign scores to the frequency of health education, and latent profile analysis was conducted on each score to explore the categories of health education conducted by medical staff.Results:2 792 questionnaires were effectively collected, among which 2 792 medical staff were surveyed, including 1 009 doctors, 1 609 nurses, and 174 technicians and pharmacists. The scores for the frequency of health education conducted in six dimensions: health education in the media or outside the hospital, health knowledge lectures in the hospital, outpatient health education, inpatient health education, health education during follow-up, and health prescriptions were (1.45±0.68) points, (1.68±1.01) points, (2.65±1.65) points, (2.76±1.74) points, (3.24±1.58) points, and (2.59±1.71) points respectively. According to latent profile analysis, healthcare personnel conducting health education could be divided into four categories: low development group (46.6%, 1 300 people), high development group (4.6%, 129 people), inpatient/follow-up development group (19.4%, 541 people), and outpatient/follow-up development group (29.4%, 822 people). The hospital level and profession of medical personnel in each category were different, and the differences were statistically significant( P<0.001). Conclusions:Medical staff in Beijing mainly carry out health education at such stages as patient follow-up, inpatient, and outpatient, but there is insufficient health education accessible in the media or outside the hospital. There are differences in the health education situation of medical personnel at different levels of hospitals and professions. It is recommended to build an efficient health education management system, actively explore new media-based health education channels, and reasonably allocate health education resources to comprehensively improve the health education of medical staff.

Purpose: The prevalence of multi-morbidities with colorectal cancer (CRC) is known to be increasing. Particularly prognosis of CRC patients co-diagnosed with metabolic syndrome (MetSyn) was largely unknown. We aimed to examine the death risk of CRC patients according to the multiple MetSyn morbidities. Materials and Methods: We identified CRC patients with MetSyn from the electronic medical records (EMR) systems in five independent hospitals during 2006-2011. Information on deaths was jointly retrieved from EMR, cause of death registry and chronic disease surveillance as well as study-specific questionnaire. Cox proportional hazards regression was used to calculate the overall and CRC-specific hazards ratios (HR) comparing MetSyn CRC cohort with reference CRC cohort. Results: A total of 682 CRC patients in MetSyn CRC cohort were identified from 24 months before CRC diagnosis to 1 month after. During a median follow-up of 92 months, we totally observed 584 deaths from CRC, 245 being in MetSyn cohort and 339 in reference cohort. Overall, MetSyn CRC cohort had an elevated risk of CRC-specific mortality (HR, 1.49; 95% confidence interval [CI], 1.07 to 1.90) and overall mortality (HR, 1.43; 95% CI, 1.09 to 1.84) compared to reference cohort after multiple adjustment. Stratified analyses showed higher mortality risk among women (HR, 1.87; 95% CI, 1.04 to 2.27) and specific components of MetSyn. Notably, the number of MetSyn components was observed to be significantly related to CRC prognosis. Conclusion Our findings supported that multi-morbidities of MetSyn associated with elevated death risk after CRC. MetSyn should be considered as an integrated medical condition more than its components in CRC prognostic management.
