Citrate anticoagulation hemoperfusion in the treatment of 273 patients / 中华劳动卫生职业病杂志

Early hemoperfusion in poisoned patients can remove poisons rapidly and effectively, which plays an important role in improving the prognosis of patients. The key of hemoperfusion therapy is the safe and effective anticoagulation. The local citrate anticoagulation effect acid is good, it also has little effect on the systemic coagulation mechanism and internal environment of patients, so it is worthy of promotion. We retrospectively analyzed the clinical data and treatment of 273 patients who were poisoned by citrate anticoagulant in the emergency intensive care unit of the Second Affiliated Hospital of Shandong First Medical University, aiming at perfusion of citrate anticoagulant in patients with poisoning. Provide a certain clinical reference.

Comparative study of different methods of blood purification treatment of paraquat intoxication / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To investigate the different effect of three methods of blood purification for paraquat poisoning patients:hemoperfusion (HP), hemoperfusion combined with hemodialysis (HP + HD), hemoperfusion combined with continuous veno-venous hemofiltration (HP + CVVH).</p><p><b>METHODS</b>72 cases of paraquat poisoning patients were divided into three groups after giving conventional therapy HP group, HP + HD group, HP + CVVH group. Compared the rate of decline concentrations of paraquat in blood, the liver and the kidney damage between before and after blood purification and contrast the mortality in three groups after different method of blood purification.</p><p><b>RESULTS</b>The rate of decline concentrations of paraquat in blood of the HP + HD group and HP + CVVH group were both significantly greater than the HP group, but this result of HP + HD group has no significant difference compared with HP + CVVH group; Among the three groups of patients after 72 hours, the degree of dysfunction of liver of the HP + HD group and HP + CVVH group were both significantly lower than the HP group, whilely the degree of dysfunction of kidney of the HP + HD group was significantly lower than the HP group and the HP + CVVH group. The survival time of the HP + HD group and the HP + CVVH group were significant linger than the HP group, but the comparison among the three groups had no significant difference in mortality.</p><p><b>CONCLUSION</b>Three blood purification methods can effectively remove paraquat absorbed into the blood, and the hemoperfusion combined with hemodialysis or continuous veno-venous hemofiltration can effectively reduce the degree of damage of liver and kidney and also can prolong survival time, but did not significantly improve the survival rate of patients.</p>

The comparision between two international QOL questionnaire of lung cancer:EORTC QLQ-LC43 and FACT-L / 中国癌症杂志

Background and purpose:Quality of life (QOL) questionnaires are tools to assess the quality of life of patients. How to choose a proper questionnaire is the fi rst problem of QOL assessment in clinic research. However, there is few report on it. Our current research compares the data obtained from two world-wide used QOL questionnaire of lung cancer patients EORTC QLQ-LC43 (European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire-Lung Cancer43) and FACT-L (Functional Assessment of Cancer Treatment-Lung) by various statistic methods in order to show differences between the two questionnaires and to provide some suggestions for choosing questionnaires to assess patients’ QOL in clinic research. Methods:The clinic data were obtained from 125 lung cancer patients by two different international QOL questionnaires of lung cancer patients EORTC QLQ-LC43 and FACT-L, and analyzed by various statistic methods such as Pearson correlation analysis, canonical correlation analysis and multiple regression. In addition, we also compare the general modality such as the frame, item numbers and the contents of the subscales, etc. Results:Of the two QOL there are some parts similar in length, ranking type and time construction, even in items. They all contain items in measuring the physical domain, emotion domain, function domain, society domain and lung domain. Correlations between corresponding subscales of the FACT-L and the EORTC QLQ-LC43 are all signifi cant ranging from r=0.331 for the social domain to r=0.664 for the emotional domain. Canonical correlation analysis for the two sets of subscales revealed there are four signifi cant canonical variables (canonical correlation coeffi cient r=0.87 to 0.26 and overall redundancy about 41% ). The eight EORTC QLQ-LC43 subscales are well represented by the fi ve FACT-L subscales (multiple linear regression, R 2=0.531 to 0.766) and the fi ve FACT-L subscales (except relationship with doctors) are also well represented by EORTC QLQ- LC43 subscales (R 2=0.537 to 0.823). The proportion of the corresponding subscale in the total explanation is 50% to 90%. Conclusion:These two questionnaires cover some common parts, but they measure different contents of QOL. Though have the same name, some domains cann’t be compared directly. The two questionnaires cann’t be alternative and the results of them shouldn’t be compaired directly. Both questionnaires are suited for clinic study (e.g compare the effect of two different theropies). But each has its own characters and should be chosen according to reseach goals.
