Objective:To investigate the efficacy and safety of tenofovir amibufenamide in patients over 65 years old with chronic hepatitis B and liver cirrhosis.Methods:We recruited 45 patients in Linyi People's Hospital with chronic hepatitis B and liver cirrhosis who were treated with TMF antiviral therapy for 48 weeks, compared the virologic response rate and HBV DNA decrease level at 12, 24 and 48 weeks, and the changes in hepatitis B surface antigen, alanine aminotransferase, glomerular filtration rate, creatinine, triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, serum phosphorus and blood lipids, and the changes in ALT normalization rate at 48 weeks. P<0.05 was statistically significant. Results:The age of the enrolled patients was 69.0 (67.0, 72.5) years. At 12, 24, and 48 weeks of treatment, the complete virological response rates were 32.4% (12/37), 70.0% (28/40), and 84.6% (33/39) respectively, and the level of HBV DNA decreased from baseline ( P＜0.05). After 48 weeks of treatment, the level of HBsAg decreased ( P<0.05), and there was no negative HBsAg conversion and seroconversion. After 48 weeks of treatment, the level of ALT decreased ( P<0.05). At 48 weeks of treatment, the rates of ALT reverted to normality were 88.9% (16/18) and 70.4% (19/27), respectively. There was no significant difference in the levels of glomerular filtration rate, creatinine, phosphorus, triglycerides, total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol estimated at baseline before and after treatment ( P＞0.05), and no serious adverse events were observed. Conclusions:For patients over 65 years old with chronic hepatitis B and liver cirrhosis, TMF can significantly inhibit HBV DNA replication, and the ALT normalization rate is high and well tolerated.

Objective To study the relationship between lipid metabolism and liver function indexes in prediabetic population,and explore the predictive value of these indexes for prediabetes.Methods 546 patients with prediabetes who underwent physical examination in the First Affiliated Hospital of Xi'an Jiaotong University from April 2020 to August 2021 were selected as case group(PreDM group)and 546 patients with normal glucose tolerance as control group(NGT group).There was no significant difference in baseline data between the two groups after tendency matching score.The levels of lipid metabolism and liver function indicators were compared between the two groups;the correlation between lipid metabolism and liver function indicators in the PreDM group was analyzed;the influencing factors of prediabetes were screened by using binary logistic regression analysis;the predictive effect of lipid metabolism and liver function indicators on prediabetes was judged by using the ROC curve.Results Glutamic pyruvic transaminase(ALT),glutamic pyruvic transaminase/glutamic oxaloacetic transaminase ratio(ALT/AST),cholinesterase(CHE),gamma glutamyltransferase(GGT),total cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),total cholesterol/high density lipoprotein cholesterol ratio(TC/HDL-C)and triglyceride/high density lipoprotein cholesterol ratio(TG/HDL-C)in PreDM group were higher than those in NGT group(all P＜0.05).Spearman correlation analysis showed that TG/HDL-C in PreDM group had the positive correlation with ALT,ALT/AST,CHE and GGT(r=0.256,0.256,0.293,0.122,all P＜0.05).Multivariate stepwise logistic regression analysis showed that ALT/AST,GGT,TC/HDL-C and TG/HDL-C had the greatest effect on prediabetes(OR=2.124,1.027,1.196,1.260),and the combination of the four had the highest differential diagnostic value(AUC＞0.70).Conclusion There are more abnormal indexes of blood lipid and liver zymogram in prediabetic population,and the combination of ALT/AST,GGT,TC/HDL-C and TG/HDL-C is more effective in predicting prediabetes.

The risk factors,especially laboratory indicators,of prognosis after acute kidney injury (AKI) remain unclear.We conducted a retrospective survey of Chinese People's Liberation Army General Hospital from January 1,2012 to December 31,2012 according to the AKI diagnosis standard issued by Kidney Disease Improving Global Outcomes.The epidemiological features and factors influencing hospital mortality and renal function recovery were evaluated through logistic regression analysis.Among 77 662 cases of hospitalized patients,1387 suffered from AKI.The incidence rate and mortality of AKI were 1.79％ and 14.56％,respectively.Multivariate logistic regression analysis revealed that high AKI stage,age greater than 80 years,neoplastic disease,low cardiac output,increased white blood cell count,and decreased platelet count and serum albumin levels were the risk factors affecting the mortality of AKI patients.Conversely,body mass index between 28 and 34.9 was a protective factor.Increased AKI stage,tumor disease,post-cardiopulmonary resuscitation,and RRT were the risk factors of renal function recovery upon discharge.In addition to traditional risk factors,white blood cell count,platelet count,albumin,and BMI were the predictors of the mortality of AKI patients.No laboratory indicators were found to be the risk factors of renal function recovery in AKI patients.
