Objective To investigate the death of MHD patients with different blood phosphorus variability.Methods The clinical data of seventy-four cases of MHD patients with more than 3 months dialysis age in the hemodialysis center of Chaozhou Central Hospital from January 2014 to December 2016 were retrospectively analyzed.The general data and laboratory biochemical indexes were collected and according to the difference in coefficient of variation (CV),the patients were divided into two groups:high blood phosphorus variability group (CV≥0.226 mmol/L) and low blood phosphorus variability group (CV ＜0.226 mmol/L).The relationship between the coefficient of variation and all-cause mortality and cardiovascular mortality in MHD patients was analyzed.Results Among all selected patients,all-cause mortality rate was 22.9％ (17/24),12.2％ (9/74) died of cardiovascular disease,and the all-cause mortality 34.2％ (13/38)in the high blood phosphorus variability group was significantly higher than that in the other one1 1.1％ (4/36) (x2=5.574,P＜0.05);but there was no significant difference between the two groups in cardiovascular disease mortality (X2 =0.962,P＞0.05).And there was no significant difference between the serum phosphorus standard group and the substandard group in the all-cause mortality and the cardiovascular disease mortality (x2 =0.389,0.065,P ＞ 0.05).There was no significant difference in the cumulative survival rate between the patients in the serum phosphorus standard group who experienced all-cause death and cardiovascular disease death and the patients in the substandard group (P＞0.05).In the high blood phosphorus variability group,patients who reached serum phosphorus standard had higher total mortality rate and cardiovascular disease mortality rate,compared with patients who achieved serum phosphorus standard or experienced low phosphorus deficiency in the low blood phosphorus variability group (x2=0.211,0.197,P ＞0.05).Kaplan/Meier analysis showed that the cumulative survival rates of all patients with all-cause death and cardiovascular death in the high blood phosphorus variability group were significantly lower than those in the low level group (P＜ 0.05).Conclusion All-cause mortality and cardiovascular disease mortality are high in MHD patients with large variability in blood phosphorus,and the degree of blood phosphorus variation is helpful to predictthe death of MHD patients.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.
