Objective To investigate the effect of diet and lifestyle on cardiovascular comorbidity in elderly diabetic patients in community. Methods A total of 437 elderly patients with diabetes mellitus in a community of Huai'an City were divided into comorbidity group and non-comorbidity group according to the presence or absence of cardiovascular comorbidity. Dietary and lifestyle data were collected by self-designed questionnaires. The differences between the two groups were compared. Multivariate logistic regression was used to analyze the influencing factors of comorbidity of diabetes mellitus with cardiovascular disease. Results Among the surveyed patients, 184 (42.11%) had at least one comorbidity of cardiovascular disease, with the most common diseases being hypertension in 93 patients (21.28%), coronary heart disease in 71 patients (16.25%), and stroke in 42 patients (9.61%). Multivariate logistic regression analysis showed that: the risk of comorbidity in the male group was 1.528 times higher than that in the female group; the risk of comorbidity among individuals with inadequate carbohydrate intake was 1.520 times higher than that of individuals with adequate carbohydrate intake; the risk of comorbidity in the group with smoking history > 30 years was 1.299 times higher than that in the group ≤ 30 years; the risk of comorbidity was 49.80% lower in the group with tea preference than that in the group without tea preference; and the risk of comorbidity in the group not meeting the standard for exercise was 1.492 times higher than that in the group meeting the standard for exercise. All these differences were statistically significant (P<0.05). Conclusion The comorbidity of cardiovascular disease in elderly diabetic patients in community should not be ignored, and targeted dietary and lifestyle interventions are helpful for the prevention and control of comorbidity.

Objective To investigate the potential role of caveolin-1 ( CAV-1 ) on membrane estrogen receptor (mER) mediated proliferation of endothelial progenitor cells (EPCs).Methods Bone marrow (BM) -derived EPCs were cultured.The proliferation of EPCs induced by estradiol ( E2 ) -BSA in the absence or presence of ICI 182,780 (a pure ER inhibitor),MβCD and CAV-1 siRNA was determined by [3H]-thymidine incorporation.The expression of CAV-1 was detected by Western blot.Results Proliferation of EPC peaked after 10-8 mol/L E2-BSA culture for 24 h (87.5％ increase vs.control),and this effect could be inhibited by estrogen receptor blocker ICI 182,780,indicating that mER-initiated membrane signaling pathways was involved in the proliferation effect of estrogen on EPC.Both cholesterol depletion and CAV-1 siRNA significantly attenuated E2-BSA induced [3H ]-thymidine incorporation.Western blot result confirmed that cholesterol depletion or CAV-1 siRNA significantly decreased CAV-1 protein expression ( - 18.6％ or -41.2％ vs.10-8 mol/L E2-BSA alone).Conclusion Our results suggested that estradiol promoted EPC proliferation through activating CAV-1 pathway.

OBJECTIVETo construct a chimeric SEA-hPLAP-1 cDNA with gene splicing by overlap extension.

METHODSThe SEA gene and a DNA fragment encoding the signal for GPI-anchor attachment of hPLAP -1 were amplified by PCR. The two amplified gene sequence was annealed to form a chimeric GPI- anchored SEA molecule with gene splicing by overlap extension. The resulting chimera was cloned in pGEM-T vector and verified by sequencing analysis.

RESULTA chimeric SEA-hPLAP-1 cDNA was successfully constructed with gene splicing by overlap extension.

CONCLUSIONGene splicing by overlap extension is a successful specific PCR technique for gene recombination.

OBJECTIVETo explore the inhibition and molecular mechanism of icaritin (ICT) combined doxorubicin (DOX) on human osteosarcoma MG-63 cells in vitro.

METHODSThe control group, ICT groups (10, 20, 40, 80, and 160 µmol/L), DOX groups (1, 2, 4, 8, and 16 µg/mL), and combination groups (20 µmol/ L ICT +1 µg/mL DOX, 20 µmol/L ICT +2 µg/mL DOX, 20 µmol/L ICT +4 µg/mL DOX, 40 µmol/L ICT +1 µg/mL DOX, 40 µmol/L ICT +2 µg/mL DOX, 40 µmol/L ICT +4 µg/mL DOX, 80 µmol/L ICT +1 µg/mL DOX, 80 µmol/L ICT +2 µg/mL DOX, 80 µmol/L ICT +4 µg/mL DOX) were set up. Human osteosarcoma MG-63 cells were respectively cultured and their effects on morphological changes were observed using inverted phase contrast microscope after 24-and 48-h intervention. The cell proliferation inhibition rate of each group was de- termined using CCK-8, and IC50 calculated. The MG-63 apoptosis rate was detected using Annexin V-FITC/ PI double dye flow cytometry. Expression levels of bcl-2, caspase-3, and p21 were detected using RT-PCR.

RESULTSICT and DOX could obviously inhibit the proliferation of MG-63 cell. Along with ICT concentration increasing from 10 µmol/L to 160 µmol/L, the cell proliferation inhibition rate also increased gradually from 9.67% ± 3.62% to 89.18% ± 9.66%. The IC50 was 46.93 µmol/L and 3.87 µg/mL respectively. ICT and DOX could cause either early or late stage apoptosis, down-regulate Bcl-2 gene expression, and up-regulate gene expressions of Caspase-3 and p21 respectively (P < 0.05). Aforesaid changes were more obviously seen in combination groups than in lCT groups and DOX groups (P < 0.05).

CONCLUSIONCT combined DOX had additive or synergistic inhibition effect for the proliferation of osteosarcoma MG-63 cells, which might be related with regulating gene expressions of bcl-2, caspase-3, and p21.

Long-term excessive iodine intake resulted in an increased TT_4 level and a decreased TT_3 level in maternal serum,meanwhile,hepatic and renal type 1 deiodinase activity decreased dose-dependently.A significant reduction in type 2 deiodinase ( D2 ) activity of 12.5 d placenta was found in 3.0 mg/L or above groups.For 19.5 d uterus,D2 activity decreased and type 3 deiodinase activity increased.The results suggest that excessive iodine has an effect on the embryonic development by regulating maternal-fetal thyroid hormone metabolism.

The study found that the presence of intestinal microbiota is not only important for the metabolism of essential nutrients in the body, but also plays a key role in the development of the body′s immune system in recent years. Partial microbiota, through natural selection and co-evolution with the host, forms symbiotic relationships with host microbes that are inseparable from host physiology in mice. Symbiotic flora affects the formation of the body′s immune system by affecting innate and adaptive immunity and the development of various regulatory mechanisms. The destruction of the microbial ecosystem in the intestine can lead to the occurrence of many diseases,especially those related to the immune system. Peripheral immune organs always receive a number of immune cells colonized by antigen stimulation. So,the intestinal flora plays an important role in maintaining the function of immune cells. This article will investigates the effects of mouse-related intestinal flora on peripheral immune organ function.

OBJECTIVE: To explore the feasibility of detecting of Y-STR of fetal DNA in maternal plasma using Ion Torrent PGM™ System. METHODS: A total of 16 fetal DNA samples from maternal plasmas (8 cases from 38 weeks gestational age and 8 ones from 12 weeks) were prepared and a multiplex assay with 7 STR loci (DYS390, DYS391, DYS393, DYS438, DYS437, DYS456, DYS635) was designed for multiplex-PCR amplification. Using Ion Torrent PGM™ System, the results of Y-STR sequences and capillary electrophoresis were obtained and compared. RESULTS: Y-STR specific alleles were detected in the maternal plasma of all the pregnant women having male babies of second and third trimester, which were higher than that detected by capillary electrophoresis. Consistent Y-STR genotypes were observed between fetal DNA from maternal plasma and genomic DNA from the newborn babies. CONCLUSION Based on Ion Torrent PGM™ System, the prenatal Y-STR detection method may provide a high-sensitive and high-throughput choice for prenatal STR detection in forensic testing.
