Objective .To prove aristolochic (AA) caused vascular endothelial cells (VEC) injury via intracellular calcium overloa-ding and investigate the mechanism of calcium dobesilate antagonism. Methods Human umbilical vein endothelial cells (HUVEC) were cultured in vitro, and randomly divided into three groups: Control group, AA group, intervention group. Microscope and transmission elec-tron microscopy were used to observe changes of cell morphology and ultrastructure. ELISA method were applied to determine thrombomedu-lin (TM) in cell culture supernatant, fluorescent indicator FLuo-3/AM and intracellular calcium concentration ([Ca2+]. Results TM val-ue and average [Ca2+] i of AA group were significantly higher than that of control group (P < 0.05). Compared with the AA group, when the concentration of calcium dobesilate was 25 μM or 50 μM, TM value and average [Caz +] significantly decreased in intervention group (P < 0.05). Compared with control group, endoplasmic reticulum was pool expansion shaped, and mitochondrial cristae was absent in AA group cells. Endoplasmic reticulum and mitochondria patterns in the intervention group cells showed some improvement, compared with AA group. Conclusion AA induced VEC calcium overloading, 'I'M secretion and injury of endothelial ceils, endoplasmic reticulum and mito-chondria destruction. Dabesilate calcium could protect endoplasmic reticulum and mitochondria and reduce AA induced VEC calcium over-loading, and these could protect VEC.

Objective With multi?center investigation, to assess the life quality of patients with maintained hemodialysis (MHD) in Liaoning Province and to explore the relationship among the mineral metabolism, the life quality of the patients with MHD, and the repeated hospitalization within the latest three years. Methods 1192 patients with hemodialysis (at least 3 months) from January to March in 2015 at ten blood purification centers in Liaoning Province were selected for the cross?————————sectional survey. The Kidney Health?related Quality of Life (HRQOL) version 1.3 was used to evaluate the MHD patients' life quality. The total length of hospitalization was divided into four groups: 0 days, 3 to 15 days, 16 to 30 days and above 30 days. Results When serum calcium value ranged from 2.1 to 2.5 mmol/L, kidney?disease component summary (KDCS), mental component summary (MCS), physical component summary (PCS) and SF?36+KDCS corresponded to a higher value (P<0.05). When serum phosphorus value ranged from 1.13 to 1.78 mmol/L, KDCS and SF?36+KDCS corresponded to a higher value (P<0.05). When the calcium phosphorus product value ranged from 40.68 to 49.94, MCS corresponded to a higher value (P<0.05). KDCS showed a linear correlation with age (P<0.001), dialysis age, serum calcium (less than or equal to 2.5 mmol/L) (P<0.05); PCS showed a linear correlation with age (P<0.001) and dialysis age (P<0.05); SF?36+KDCS showed a linear correlation with age (P<0.001), and serum calcium (less than or equal to 2.5 mmol/L) (P<0.05), while age and dialysis age were negatively correlated. The hospitalization days showed a linear correlation with age, dialysis age (P<0.001) and serum phosphorus, calcium phosphorus product value (P<0.05), while dialysis age and calcium phosphorus product value were negatively correlated. Among different groups of total hospitalization days in three years, age, hemodialysis age, serum calcium, serum phosphorus, calcium?phosphorus product value and quality of life values were all statistically significant (P<0.05). Conclusions The life quality of patients with MHD were correlated with serum calcium, phosphorus, calcium and phosphorus product value, iPTH, dialysis age and age, while age and dialysis age were of negative correlation. The total number of hospitalization days in 3 years was closely linearly correlated with age and dialysis age, significantly correlated with serum phosphorus, calcium and phosphorus product value, while dialysis age, calcium and phosphorus product value were in a negative correlation. The total number of hospitalization in 3 years was correlated with the patients' age, dialysis age, serum calcium, serum phosphorus, calcium and phosphorus product value and quality of life.

Objective To investigate the accuracy of body mass index (BMI) as the evaluation standard for obesity in Miao adults in Guangxi, to find out the BMI cutoff value suitable for the evaluation standard of adult obesity, and to provide an accurate and reliable reference value for the prevention and treatment of obesity in Miao nationality adults. Methods Using a cross-sectional design, residents aged 18 years or older in the Miao villages in Rongshui Miao Autonomous County, Guangxi, were selected as the research subjects, and their body composition was measured. The percent body fat (PBF) standard was used as the ^“gold standard^” for obesity, and the BMI standard for obesity in Chinese adults was used as the positive screening standard. The accuracy of the BMI standard was evaluated, and the ROC curve analysis was used to determine the optimal BMI cutoff value for obesity in Miao adults. Results The detection rate of obesity of Miao adults in Guangxi by BMI method was lower than that by PBF method (10.3% vs 19.0%, χ²=426.62, P<0.001). The results of reliability evaluation showed that BMI was in good agreement with PBF in judging obesity (Kappa=0.59, P<0.001). BMI as a screening criterion for obesity in Miao adults showed high specificity and low sensitivity, low Yordon index, high positive predictive value and high positive likelihood ratio, and low negative predictive value and high negative likelihood ratio. When the PBF was used as the ^“gold standard^”, BMI had a good diagnostic performance for obesity in Miao adults (AUC=0.959, P<0.001). The optimal BMI cutoff points for obesity in adults of Miao nationality in Guangxi were 25.85 kg/m² and 25.55 kg/m² for men and women, respectively. Conclusion BMI is of great value for the diagnosis of obesity in Miao adults, but it should not be used as an exclusion criterion for obesity. Especially in the case of a small sample size, the risk of misclassification bias is relatively high.
