ABSTRACT
Objective:To investigate the effects of sustained low-efficiency hemodialysis combined with hemoperfusion on routine blood indicators and inflammatory factors in patients with sepsis-induced acute kidney injury.Methods:Eighty-six patients with sepsis-induced acute kidney injury who received treatment in Yantai Laiyang Central Hospital from April 2018 to April 2021 were included in this study. They were randomly divided into an observation group and a control group, with 43 cases in each group. All patients received conventional supportive treatment. The control group received continuous renal replacement therapy and the observation group received sustained low-efficiency dialysis combined with hemoperfusion. Before and after treatment, routine blood indicators [hemoglobin (Hb), white blood cell (WBC) count, platelet (PLT) count, albumin (Alb)], inflammatory factors [interleukin-6 (IL-6), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), procalcitonin PCT)], renal function indicators [serum creatinine (Scr), blood urea nitrogen (BUN)], The Acute Physiology and Chronic Health Evaluation (APACHE) II score, length of hospital stay, and 28-day mortality rate were compared between the two groups.Results:Before treatment, there were no significant differences in Hb, WBC count, PLT count, Alb, IL-6, CRP, TNF-α, PCT, Scr, BUN, and APACHE II score between the two groups ( t = 0.04, 0.95, 0.23, 0.67, 1.54, 0.75, 0.98, 0.23, 1.04, 0.44, 0.07, all P > 0.05). After treatment, serum levels of Hb and Alb in each group were significantly increased compared with those before treatment. After treatment, serum levels of Hb and Alb in the observation group were (105.29 ± 15.80) g/L, (39.25 ± 7.87) g/L, respectively, which were significantly higher than (98.55 ± 12.93) g/L and (33.38 ± 7.29) g/L in the control group ( t = 2.16, 3.58, both P < 0.05). After treatment, WBC count, PLT count, IL-6, CRP, TNF-α, PCT, Scr, and BUN levels, and APACHE II score in each group were significantly decreased compared with those before treatment. After treatment, WBC count, PLT count, IL-6, CRP, TNF-α, PCT, Scr, and BUN levels, and APACHE II score in the observation group were (10.28 ± 1.87) × 10 9/L, (129.32 ± 14.79) × 10 9/L, (59.00 ± 12.77) μg/L, (22.41 ± 5.01) mg/L, (28.41 ± 4.77) μg/L, (18.41 ± 2.78) μg/L, (162.01 ± 21.04) μmol/L, (7.38 ± 1.17) mmol/L, (11.28 ± 3.60) points, respectively, which were significantly lower than (12.32 ± 2.27) × 10 9/L, (137.39 ± 18.30) × 10 9/L, (79.35 ± 14.36) μg/L, (29.31 ± 6.37) mg/L, (34.33 ± 5.38) μg/L, (22.32 ± 3.35) μg/L, (184.06 ± 24.03) μmol/L, (9.87 ± 1.66) mmol/L, (14.65 ± 3.38) points in the control group ( t = 4.54, 2.24, 6.94, 5.58, 5.39, 5.89, 4.52, 8.03, 4.47, all P < 0.05). The length of intensive care unit stay in the observation group was significantly shorter than that in the control group [(11.63 ± 2.18) days vs. (14.07 ± 2.71) days, t = 4.60, P < 0.05]. There was no significant difference in 28-day mortality rate between the two groups ( χ2 = 1.36, P > 0.05). Conclusion:Sustained low-efficiency dialysis combined with hemoperfusion is effective on sepsis-induced acute kidney injury. The combined therapy can improve routine blood indicators, inhibit inflammatory reactions, promote renal function recovery, and decrease the mortality rate to a certain degree.
ABSTRACT
Objective:To study the association between preoperative hemoglobin amount and incidence of lower limb deep vein thrombosis (DVT) in patients with lower limb fracture.Methods:A retrospective study was performed of the 2, 482 patients with lower limb fracture who had been treated at Department of Orthopaedics Trauma, Honghui Hospital Affiliated to Xi'an Jiaotong University from July 2014 to August 2019. They were 1, 174 males and 1, 308 females with an age of (60.6±19.3) years. Recorded were the patients' age, gender, injury time, hemoglobin amount, D-dimer measurement, combined medical conditions, time and results of ultrasound vein examination on both lower extremities. According to the ultrasound results, the patients were divided into a thrombosis group and a thrombosis-free group. The 2 groups were compared in hemoglobin amount. Logistic regression was used to analyze the relationship between preoperative hemoglobin amount and incidence of lower limb DVT. The patients were divided into 5 groups according to the quintile of hemoglobin amount; the incidences of thrombosis were compared between the 5 groups.Results:The total incidence of DVT in this cohort was 29.53%(733/2, 482). The hemoglobin amount in the thrombosis group was (116.57±19.24) g/L, significantly lower than that in the thrombosis-free group (124.76±19.79) g/L ( P<0.05). The preoperative hemoglobin amount was a risk factor for incidence of DVT after a lower limb fracture ( OR=0.985, 95% CI: 0.980 to 0.990, P<0.001). As the quintile level of hemoglobin increased, the incidence of DVT showed a downward trend. In comparison of the group with the highest DVT incidence (40.58%) and the group with the lowest DVT incidence (17.27%), the risk increased by 2.386 times (95% CI: 1.718 to 3.315). Conclusions:The preoperative hemoglobin amount can affect the DVT incidence after a lower limb fracture, and a low hemoglobin amount may more likely lead to lower limb DVT.

ABSTRACT
BACKGROUND:Pasteurization is a perfect method for albumin virus inactivation, which may not be required for virus inactivation validation. However, there are no systematical reports concerning virus inactivation of hemoglobin blood substitutes. OBJECTIVE:To explore the effects of pasteurization on the physicochemical properties and biological function of hemoglobin blood substitutes. METHODS:Appropriate cord blood samples were taken fol owed by centrifugation, washing blood, rupture of membranes, stabilizer treatment. In the control group, the samples were placed in 55℃water bath, and when the temperature of hemoglobin solution reached (55±1)℃, a heat treatment began and lasted for 2 hours. In the pasteurization group, the samples were placed in 60℃water bath, and when the temperature of hemoglobin solution reached (60±1)℃, a heat treatment began and lasted for 10 hours. The heating process was under continues nitrogen protection. Then, the hemoglobin solution was placed in ice bath and cooled to below 4℃fol owed by low-speed centrifugation and filtration via microporous membrane, purification and viral inactivation thereby to obtain cord blood hemoglobin. RESULTS AND CONCLUSION:The products in the pasteurization group were al red clear liquid. There was no significant difference between the two groups in the yield, methemoglobin concentration, and oxygen-carrying capacity. The purification of the two groups was more than 98%. Two kinds of purification methods had no effects on the oxygen-carrying capacity of hemoglobin. Therefore, pasteurization method can replace thermosensitive purification method of 55℃, 2 hours. The pasteurization method wil not only ensure the physicochemical and biological properties of hemoglobin, but also achieve the purpose of virus inactivation.
ABSTRACT
BACKGROUND:At present, occlusion of the drainage tube was commonly used to reduce the drainage volume after total hip arthroplasty so as to promote the incision healing and hip function rehabilitation. However, the occlusion time is a problem deserving further investigations. OBJECTIVE:To research the effects of temporarily clamping drainage tube on drainage volume in early stage after total hip arthroplasty. METHODS:From January to October 2013, 112 patients received unilateral total hip arthroplasty in the First Ward, Department of Orthopedics, First Affiliated Hospital, Zhengzhou University in China. They were randomly divided into four groups according to the admission time (n=28):occlusion of the drainage tube for 2, 4 and 6 hours and without occlusion of the drainage tube. Al tubes were pul ed out in postoperative 48 hours. Moreover, 48-hour postoperative hemoglobin and drainage volume, the healing of incision and the score of hip joint function when patients were fol owed up at 1.5 months postoperatively were recorded accurately. RESULTS AND CONCLUSION:48-hour hemoglobin drop level and 48-hour incision drainage volume were highest in the non-occlusion group, fol owed by 2-hour occlusion group, 4-hour occlusion group and 6-hour occlusion group (P0.05). Incision infection and tension split were not seen in each group. Six cases affected subcutaneous ecchymosis and swel ing accompanied by pain and four cases suffered from the venous plexus thrombosis of the calf muscle in the 6-hour occlusion group. One case experienced fat liquefaction separately in the 4-hour occlusion group and non-occlusion group. These results suggested that temporary occlusion of the drainage tube in the early stage of total hip arthroplasty could reduce the drainage volume of incision. The suitable time of clamping drainage tube was 4 hours, and there were no adverse effects on healing of incision and recovery of hip function.

Hemoglobinopathy is a kind of hereditary hematonosis caused by the disproportion among normal hemoglobins or formation of abnormal hemoglobins.Hemoglobin analysis plays an important role in screening and diagnosing hemoglobinopathy.Emerging methods have been applied continuously to hemoglobinometry since the early 20th century.Nowadays,agarose gel electrophoresis,high performance liquid chromatography and capillary electrophoresis are widely used with mass spectrometry as the latest applied method.All these methods have their own features.Appropriate combination of these methods will lead to more scientific and reliable results.
ABSTRACT
The incidence of α-thalassemia and β-thalassemia is high in Guangxi,Guangdong,Sichuan and other province in China.Because no effective approach to thalassemia treatment could be used clinically now,the most cost-effective strategy to control this disease is to prevent the birth of babies with severe form of thalassemia.It is important to make effective screening and correct diagnosis of thalassemia by laboratory test.Laboratory diagnosis of thalassemia includes routine diagnosis and genetic diagnosis.The laboratory routine tests are some hematology examination,comprising red blood cell indices,erythrocyte osmotic fragility test,hemoglobin analysis,and others.Anyone alone of these laboratory parameters can not be used to diagnose the carrier of thalassemia.It is necessary to combine these tests to make screening diagnosis.The final diagnosis of thalassemia need to perform the gene mutation examination or globin train analysis.Technologies for gene mutation detection have been the main and gold standand method of diagnosing thalassemia now.
ABSTRACT
Thalassemias are a group of inherited disease which is caused by globin gene defects.Identification and quantification of hemoglobin play a very important role for the screening and diagnosis of thalassemia,especially the quantitative analysis of Hb A2 and Hb F.Through past 60 years,the methods for Hemoglobin analysis have been developed from starch gel electrophoresis,paper electrophoresis,cellulose acetate electrophoresis,agarose gel electrophoresis,column chromatography,high-performance liquid chromatography till capillary electrophoresis,Its development closely associates with the research on thalassemia.No matter what kind of methods is chosen,quality control is very important.
ABSTRACT
PURPOSE: At present, the hemoglobin count is one of the most commonly performed clinical laboratory tests in the emergency department. However, the conventional method is invasive and permits only intermittent assessments. The aim of this study was to determine whether non-invasive hemoglobin measurements (SpHb) produce comparably accurate results to laboratory hemoglobin tests (tHb) in patients presented to the emergency department. METHODS: From May to July 2009, 217 patients who required hemoglobin tests after presenting to the emergency department of a hospital were enrolled. We measured hemoglobin values using the conventional method (tHb), and the non-invasive method (SpHb). The study population was classified into two groups: 'non-bleeding' and 'bleeding'. The concordance between tHb and SpHb was analyzed by the Pearson's correlation coefficient. RESULTS: A total of 217 data pairs were collected from 217 subjects, 193(88.9%) non-bleeding patients, 24(11.1%) bleeding patients. A total of 114 subjects were male (52.5%). The Pearson's correlation coefficient between tHb and SpHb was 0.814(p=0.000). In the 'non-bleeding' and 'bleeding' groups, the Pearson's correlation coefficients between tHb and SpHb were 0.779(p=0.000) and 0.788(p=0.000) respectively. CONCLUSION: Non-invasive SpHb measurement provides clinically acceptable accuracy compared to the conventional laboratory method (tHb) in the setting of the emergency department.
