BACKGROUND Major adverse cardiac events(MACE) in elderly patients with biliary diseases are the main cause of perioperative accidental death, but no widely recognized quantitative monitoring index of perioperative cardiac function so *** To investigate the critical values of monitoring indexes for perioperative MACE in elderly patients with biliary *** The clinical data of 2.8 elderly patients with biliary diseases in our hospital from May 2.16 to April 2.2. were retrospectively analysed. According to whether MACE occurred during the perioperative period, they were divided into the MACE group and the non-MACE *** In the MACE compared with the non-MACE group, postoperative complications, mortality, hospital stay, high sensitivity troponin-Ⅰ(Hs-TnI), creatine kinase isoenzyme(CK-MB), myoglobin(MYO), B-type natriuretic peptide(BNP), and Ddimer(D-D) levels were significantly increased(P 2.65 pg/mL and 0.965 mg/L, *** The postoperative BNP and D-D were independent risk factors for perioperative MACE, with the critical values of 382.65 pg/mL and 0.965 mg/L respectively. Consequently, timely monitoring and effective maintenance of perioperative cardiac function stability are of great clinical significance to further improve the perioperative safety of elderly patients with biliary diseases.

Background The mitochondrial displacement loop （D-loop） accumulates mutations and single nucleotide polymorphisms （SNPs） at a higher frequency than other regions of mitochondrial DNA （mtDNA）.We previously identified disease riskassociated SNPs in the D-loop of chronic kidney disease （CKD） patients; in this study,we investigated the association of age-at-onset and D-loop SNPs in CKD *** The D-loop region of mtDNA was sequenced in 119 CKD patients attending the Fourth Hospital of Hebei Medical university between 2.02.and *** age-at-onset curve of the CKD patients was calculated using the KaplanMeier method at each SNP site,and compared using the log-rank *** The mean age of 119 CKD patients was （55.6±14.2. years,and 56.3% were *** mean estimated glomerular filtration rate （eGFR） was （81.2.12.4） ml·min^-1·1.73 m^-2.with 79.8% （n=95） of patients having an eGFR 〈60 ml·min^-1·1.73 m^-*** participants had an eGFR 〉30 ml·min^-1·1.73 m^-*** age-at-onset for CKD patients who smoked was significantly lower than that of non-smoking CKD *** SNP sites of nucleotides 150C/T were identified for their association with age-at-onset using the log-rank *** age-at-onset of patients with the minor allele T genotype was significantly lower than that of patients with the C genotype at the 150 SNP site （P=0.010）.Conclusions Genetic polymorphisms in the D-loop appear to be predictive markers for age-at-onset in CKD ***,the analysis of genetic polymorphisms in the mitochondrial D-loop may help identify CKD patient subgroups at high risk of early onset disease.
