ABSTRACT
OBJECTIVE@#To investigate the effects of wogonoside on high glucose-induced dysfunction of human retinal microvascular endothelial cells (hRMECs) and streptozotocin (STZ)-induced diabetic retinopathy in rats and explore the underlying molecular mechanism.@*METHODS@#HRMECs in routine culture were treated with 25 mmol/L mannitol or exposed to high glucose (30 mmol/L glucose) and treatment with 10, 20, 30, 40 μmol/L wogonoside. CCK-8 assay and Transwell assay were used to examine cell proliferation and migration, and the changes in tube formation and monolayer cell membrane permeability were tested. ROS, NO and GSH-ST kits were used to evaluate oxidative stress levels in the cells. The expressions of IL-1β and IL-6 in the cells were examined with qRT-PCR and ELISA, and the protein expressions of VEGF, HIF-1α and SIRT1 were detected using Western blotting. We also tested the effect of wogonoside on retinal injury and expressions of HIF-1α, ROS, VEGF, TNF-α, IL-1β, IL-6 and SIRT1 proteins in rat models of STZ-induced diabetic retinopathy.@*RESULTS@#High glucose exposure caused abnormal proliferation and migration, promoted angiogenesis, increased membrane permeability (P < 0.05), and induced inflammation and oxidative stress in hRMECs (P < 0.05). Wogonoside treatment concentration-dependently inhibited high glucose-induced changes in hRMECs. High glucose exposure significantly lowered the expression of SIRT1 in hRMECs, which was partially reversed by wogonoside (30 μmol/L) treatment; interference of SIRT1 obviously attenuated the inhibitory effects of wogonoside against high glucose-induced changes in proliferation, migration, angiogenesis, membrane permeability, inflammation and oxidative stress in hRMECs. In rat models of STZ-induced diabetic retinopathy, wogonoside effectively suppressed retinal thickening (P < 0.05), alleviated STZ-induced retinal injury, and increased the expression of SIRT1 in the retinal tissues (P < 0.001).@*CONCLUSION@#Wogonoside alleviates retinal damage caused by diabetic retinopathy by up-regulating SIRT1 expression.

Dietary patterns were established by exploratory factor analysis. Multinomial Logistic regression model was used for analyzing influencing factors of dietary pattern.@*Results@#Three major dietary patterns were identified. Type I (37.09%) was a healthy dietary pattern; type II (33.37%) and III (29.54%) were classified into western dietary patterns. Multinomial Logistic regression models showed that living on campus (ORⅡ=1.57, 95%CI:1.33-1.85; ORⅢ=1.28, 95%CI:1.07-1.52), screen time≥2 h/d (ORⅡ=2.89, 95%CI:2.51-3.33; ORⅢ=2.14, 95%CI:1.85-2.48) were positively associated with type II and III. The monthly household income per capita≥5 000 yuan (ORⅢ=1.31, 95%CI:1.14-1.51) was positively associated with type III. Senior students (ORⅡ=0.83, 95%CI:0.73-0.95; ORⅢ=0.74, 95%CI:0.64-0.85), the level of parental education (ORⅡ=0.64, 95%CI:0.52-0.79; ORⅡ=0.67, 95%CI:0.54-0.82; ORⅢ=0.72, 95%CI:0.58-0.90; ORⅢ=0.73, 95%CI:0.59-0.89) had a negative association with type II and III.@*Conclusion@#There are three dietary patterns among urban middle school students in Guangzhou. The main influencing factors include parental education, screen time, grade, resident situation, and monthly household income per capita.
ABSTRACT
Objective@#To explore the correlation between hemoglobin and blood pressure.@*Methods@#This study adopted the cross-sectional design method. Participants were recruited from grade 2 in primary school, grade 1 from junior and senior high school taking physical examination, including the hemoglobin test, organized by the Guangzhou Municipal Primary and Secondary School Health and Health Promotion Center from January to December in 2015. Correlation between blood pressure and hemoglobin and determinants of blood pressure were analyzed.@*Results@#A total of 34 752 samples participated including 17 414 boys and 17 338 girls. Hemoglobin was negatively associated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) among girls with anemia(P<0.01). Hemoglobin was positively associated with SBP and DBP among boys and girls with normal hemoglobin level(P<0.01). With each tertile increase in blood pressure, hemoglobin level increased by 1 mmHg. Logistic regression analysis showed that compared with peers from same grade with hemoglobin level lower than P25, the risk of suffering from pre-hypertension and hypertension among students from grade 2 with hemoglobin level greater than or equal to P75, and those from junior high and senior high schools with hemoglobin level higher than or equal to P50.@*Conclusion@#Among students without anemia population, a positive correlation between hemoglobin and SBP and DBP is observed.
ABSTRACT
Objective To analyze the influence factors of poor prognosis in acute solitary pontine infarction. Methods The maximal diameter of the infarct lesion, arterial blood supply distribution and perforating artery atherosclerosis in 73 acute solitary pontine infarction patints were examined by brain MRI. The intracranial vascular stenosis was assessed by brain MRA or CTA. Carotid ultrasound was used to evaluate the atherosclerosis of extracranial artery. According to the mRS score, patients were divided into poor prognosis group ( mRS score≥3) and good prognosis group ( mRS score <3). Results Compared with those in good prognosis group, the rate of diabetes, admission and discharge NIHSS score, early progress rate, fasting blood glucose level in poor prognosis group were significantly higher,and the ratio of males was significantly lower (P<0. 05 -0. 01). Compared with those in good prognosis group, incidence of infarction with multiple blood supply, perforators atherosclerosis, vertebral basilar artery stenosis ratio and maximum diameter of infarction in poor prognosis group were significantly higher (all P<0. 01). The lesion which extended from the deep part of the pontine to the ventral side of the pontine and basilar artery stenosis were independent predictors of poor prognosis in patients with acute solitary pontine infarction (OR=22. 137, 95% CI:2. 563 -191. 228, P=0. 005; OR=28. 552, 95% CI:2. 347 -347. 313, P=0. 009). Conclusion Perforating artery atherosclerosis and basilar artery stenosis are independent predictors of poor prognosis in patients with acute solitary pontine infarction.

To understand the genetic diversity and drug resistance status of Mycobacterium tuberculosis (M. tuberculosis) circulating in Xuzhou of China, the spacer-oligonucleotide typing (Spoligotyping) and multi-loci VNTRs (variable number tandem repeats) analysis (MLVA) were utilized for the genotyping of the isolates. Drug susceptibility test (DST) was performed by the proportion method on the Lowenstein-Jensen (L-J) medium using isoniazid, rifampicin, ethambutol, and streptomycin. By Spoligotyping, 287 M. tuberculosis isolates were differentiated into 14 clusters. Then with 15-loci MLVA, these strains could be divided into 32 clusters, 228 genotypes. Of 15 VNTRs, 6 loci had the highly discriminatory powers, 6 loci presented moderate discrimination and 3 loci demonstrated less polymorphism. The DST results showed that 46 strains were resistant to at least one first-line anti-tuberculosis agent. There was a difference in the isoniazid resistance between Beijing and non-Beijing genotype strains. We concluded that the combination of Spoligotyping and 15 VNTR loci as the genotyping in our study was applicable for this region, the drug resistant isolates were identified, and the Beijing family was the most prevalent genotype in the rural counties of Xuzhou.

To investigate the molecular mechanism underlying T-bet mediated anti-neoplastic effects of cytokine induced killer [CIK] cells. Lymphocytes isolated from peripheral blood of leukemic children were induced with gamma- interferon [IFN- gamma], CD3McAb and interluki-2 [IL-2], and co-cultured with dendritic cells [DCs] to generate DC-CIK cells. The morphology and immunophenotype of these cells were determined by a light microscopy and flow cytometry, respectively. IL-2 and IFN- gamma levels released by DC-CIK cells were quantified by ELISA. Cytotoxicity of DC-CIK cells against leukemia cell lines was measured by MTT assay. FCM was used to detect CD4[+]CD25[+]Treg cells, while RT-PCR and Western blot were used to determine mRNA and protein expressions of Foxp3 and GATA3 in DC-CIK cells treated with T-bet monoclonal antibody. Induced DC-CIK cells were regular, round and transparent with variable cell volume and cellular aggregation. The main effector cells in this population were CD3[+]CD8[+] cells and CD3[+]CD56[+] cells. We demonstrated a time dependent increase in IL-2 and IFN- gamma levels after induction. DC-CIK cells were cytotoxic to B95 cells, Jhhan cells and M07e cells, with the highest cytotoxicity towards B95 cells. Treatment with mouse anti-human T-bet monoclonal antibody resulted in an increase in the proportion of CD4[+]CD25[+]Treg cells and elevation of Foxp3 and GATA3 mRNA and protein levels. DC-CIK cells induced with cytokines were strongly cytotoxic towards a number of cancer cell lines. Foxp3 and GATA3 were implicated in the T-bet mediated anti-neoplastic effects of DC-CIK cells via activation of the Th1 pathway and suppression of the Th2 and Treg pathways
