目的 分析献血者乙型肝炎病毒(HBV)核酸检测非重复反应性确认及追踪结果。方法 对1 200例于我站无偿献血者的血液样本进行非重复反应性确认,补充乙肝“两对半”检测,并对其部分单项核酸检测反应的患者予以回访结果追踪。结果 1 200份无偿献血血液样本单项核酸检测有反应性者150份(12.50%)。150份单项核酸检测有反应性样本经重新病毒核酸检测后,仍有58例样本有反应性(38.67%)、92例样本为非反应性(61.33%)。其中有18例献血者实际召回抽血,完成两次追踪,第一次追踪60~125天,第二次追踪间隔天数在160~356天,第一次追踪HBV DNA有反应(+)8例,第二次追踪仍存在反应(+);7例HBV DNA有反应者存在抗-HBc阳性(+)。核酸反应检测HBV-DNA阳性值10~17有37.25%,高于核酸反应检测值<10的4.17%(P<0.05)。结论 部分单项核酸检测反应无偿献血者存在一定的输血传播HBV风险,多为HBV隐匿性感染,此时需要重视其输血情况,屏蔽单项核酸反应性献血者。

Objective To analyze the results of nonrepetitive reactivity of HBV nucleic acid detection in blood donors. Methods 1 200 blood samples from our station were confirmed by nonrepetitive reaction, supplemented with the “two to half” test of hepatitis B, and some patients with single nucleic acid detection were followed up. Results One hundred and fifty samples (12.50%) were reactive in single nucleic acid detection in 1 200 blood samples. After the virus nucleic acid detection, 58 samples were reactive (38.67%), 92 were nonreactive (61.33%). 18 donors were actually recalled and drew blood, completed two tracking. The first tracking time was 60-125 days, the second time interval was 160-356 days. In the first tracking 8 cases had HBV DNA reaction (+) , which still had reaction in the second tracking; 7 HBV DNA positive donors had HBC antibody (+).The proportion of HBV-DNA positive with 10-17 value in mucleic acid reaction test(37.25%) was higher than that with value below 10(4.17%,P＜0.05). Conclusion Some donors with single nucleic acid detection reaction have a certain risk of transmission of HBV, most of them had hidden infection of HBV. At this time, we should pay attention to the blood transfusion and avoid the single nucleic acid reactive donors.

Methods A total of 64 patients with cirrhosis admitted to our hospital from January 2018 to January 2020 (cirrhosis group) were selected, and 64 healthy subjects admitted to our hospital during the same period (control group) were included. The clinical coagulation indexes of patients with cirrhosis were detected by automatic blood coagulation apparatus. Patients in cirrhosis group were divided into bleeding group and non-bleeding group; platelet parameters and PT test results were compared between control group and cirrhosis group, bleeding group and non-bleeding group, and patients with different liver function grades. Results Compared with the control group, the levels of PDW, PT, MPV and INR in cirrhosis group were higher, and the levels of PCT and PLT were lower (P＜0.05). Compared with liver cirrhosis non-bleeding group, the levels of PDW, PT, MPV and INR were higher in liver cirrhosis with bleeding group, and the levels of PCT and PLT were lower (P＜0.05). Compared with Child-Pugh A patients, the levels of PDW, PT, MPV and INR in Child-Pugh B and C patients with cirrhosis were higher, and the levels of PCT and PLT were lower (P＜0.05). Conclusion The test of coagulation function plays an important role in the evaluation of patients with cirrhosis, and can provide effective theoretical basis for the clinical treatment of patients with high diagnostic accuracy, which is conducive to the formulation of clinical treatment measures. Therefore, the test of coagulation function should be widely used in the diagnosis of cirrhosis.

Objective To investigate the risk factors of renal function deterioration in patients with diabetic nephropathy. Methods Retrospective cohort study was used to analyze the clinical data of 108 patients from January 2017 to May 2020 in the Third Hospital of Shandong Province. Patients were divided into diabetic nephropathy creatinine doubling group and non-doubling group. The changes of clinical data in two groups were compared and the risk factors of renal function deterioration were analyzed. Results The levels of BUN、cystatin C and ACR in the creatinine doubling group were higher than those in the creatinine non-doubling group, and the levels of eGFR、CO₂、ALB、 HGB were lower than those in the creatinine non-doubling group, the differences were statistically significant (P<0.05). However, there were no significant differences in the levels of UA, blood glucose, blood lipid, glycosylated hemoglobin, the history of diabetes and hypertension (P>0.05). The correlation analysis showed that serum creatinine was positively correlated with BUN、 eGFR、cystatin C and ACR and negatively correlated with CO₂、ALB and HGB. The results of multiple regression analysis showed that eGFR、cystatin C、ACR、ALB and HGB were independent influencing factors of renal function deterioration(all P<0.05). Conclusion Diabetic nephropathy can not only notice the routine indexes of renal function, but also observe the changes of ACR、ALB and HGB levels, which has certain value for awareing the renal function deterioration in patients.

Objective To investigate the effect of high flux dialysis mode on the improvement of β2-microglobulin clearance and hypertension in maintenance hemodialysis (MHD) patients. Methods Patients who received MHD at the Blood Purification Center of Xintang Hospital, Zengcheng District, Guangzhou from September 1, 2018 to October 31, 2018 (except for long-term low-flux dialysis patients due to self-tolerance factors)were selected. Random number table method was used to divide the patients into two groups,20 patients in each group. The control group received low flux hemodialysis, and the observation group received high flux hemodialysis. The treatment effects of the two groups were compared, levels of β2-microglobulin (β2-MG), intact parathyroid hormone (iPTH), changes in heart rate and blood pressure, and statistics on cardiovascular disease in the two groups before and after treatment at 3, 6, 12, and 18 months were recorded. Results The total effective rate in the observation group was 95.00%, which was higher than the 20.00% in the control group (P<0.05). After treatment, the levels of β2-MG and iPTH of the two groups decreased, and the observation group [(13.02±2.10) mg/L, (210.13±18.12) ng/L] was lower than the control group [(19.78±2.37) mg/L, (289.41±17.02)ng/L]; the β2-MG clearance rate of the observation group was higher than that of the control group at 3 months, 6 months, 12 months, and 18 months (P<0.05).Compared with that before treatment, the average arterial pressure and systolic blood pressure of the two groups were reduced, and the observation group was lower than that of the control group (P<0.05); the differences between diastolic blood pressure and systolic blood pressure at each time point in the control group were not significant (P>0.05); the 24-hour diastolic blood pressure and systolic blood pressure of the observation group decreased after 1, 3, 6, 12 and 18 months, compared with those before treatment (P<0.05), and were lower than those in the control group (P＜0.05).Comparison of the incidence of cardiovascular disease between the two groups: 1 case in the observation group was hospitalized for acute myocardial infarction; 2 cases in the control group were hospitalized for heart failure and 1 case was hospitalized for acute coronary syndrome; complications incidence in the two groups were compared (P>0.05). Conclusion The high flux dialysis mode can effectively improve the treatment outcomes of MHD patients, effectively remove blood toxins, lower blood pressure, and reduce the incidence of complications. It can be used in clinical practise.

Objective To explore the effect of sequential organ failure assessment (SOFA) combined with soluble programmed death factor-1 (sPD-1) level on the prognosis of patients with sepsis. Methods A total of 86 patients with sepsis in our hospital from March 2019 to March 2021 were selected and divided into survival group (59 cases) and death group (27 cases) according to their prognosis (28-day outcome). The levels of sPD-1, inflammatory cytokines, SOFA and APACHEⅡ scores of two groups were recorded. The risk factors of 28-day mortality were analyzed. The prognostic values of SOFA+sPD-1 in patients with sepsis were analyzed by ROC curve. Results Age, C-reactive protein (CRP), procalcitonin (PCT) and sPD-1 levels and SOFA, APACHEⅡ scores of death group were higher than those of survival group (P＜0.05). By Logistic regression analysis, sPD-1 level, SOFA and APACHEⅡ scores were identified as independent predictors of 28-day death in patients with sepsis (P＜0.05). After combining prediction, the area under the ROC curve of SOFA+sPD-1 was the largest (0.862), and the sensitivity and specificity were 88.89% and 88.14% respectively. Conclusion In the prognosis evaluation of patients with sepsis, both sPD-1 level and SOFA score were independent predictors of 28-day mortality, and SOFA+sPD-1 was more effective in predicting the prognosis of patients with sepsis.
