RESUMO

【Objective】 To investigate whether the psychological counseling nursing could alleviate psychological stress and reduce the incidence of adverse events in patients receiving advanced autologous apheresis (AAA) treatment. 【Methods】 A total of 253 patients who underwent AAA treatment in our department from September 2019 to February 2020 were studied and randomly divided into the observation group (n=127) and the control group (n=126). Other than the routine nursing, the patients in the observation group also received psychological counseling nursing. The scores of self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to compare the psychological stress state and the incidence of adverse events between two groups, and the nursing satisfaction was evaluated by NSNS scores. 【Results】 The SAS and SDS scores in the observation group( after receiving counseling nursing as the psychological intervention) were 30.03±5.06 and 33.59±4.49, respectively, significantly lower than those in the control group (43.55±3.68 and 42.18±4.22, respectively) (P<0.05). The incidences of adverse events (convulsions not included) in the observation group and the control group were 11.8%(15/127) vs 26.2%(33/126) (palpitation and shortness of breath), 6.3%(8/127) vs 16.7%(21/126) (sweating), 8.7%(11/127) vs 23.8%(30/126) (dizziness and numbness in mouth), and 5.5%(7/127) vs 19.8%(30/126) (nausea), respectively (P<0.05). The total nursing satisfaction rate of the observation group was 98.4% (125/127), which was significantly higher than that of the control group (92.9%, 117/126) (P<0.05). 【Conclusion】 The psychological counseling nursing can effectively relieve the psychological stress of patients receiving AAA treatment and reduce the incidence of adverse events.

RESUMO

Objective To compare the specificity, sensitivity, titers, and rapidity of four methods including papain technique, anti-globulin technique, polybrene test, and micro-column gel test for determination of IgG red blood cell antibodies. Methods Twelve kinds of IgG red blood cell antibodies such as anti-D, anti-E, anti-C, anti-c, anti-e, anti-Jk a, anti-Jk b, anti-Fy a, anti-Fy b, anti-k, anti-S, and anti-s were checked by the four methods. Results Seven kinds of IgG red blood cell antibodies including anti-D, anti-E, anti-C, anti-c, anti-e, anti-Jk a, and anti-Jk b were detected using papain technique (7/12). All of the 12 kinds of IgG antibodies were detected by anti-globulin technique (12/12). Eleven kinds of IgG red blood cell antibodies except anti-k were examined with polybrene test (11/12) and all the antibodies were also determinated by micro-column gel test (12/12). The titers of the antibodies determination suggested that papain technique was less sensitive than other three methods, while the micro-column gel test was more sensitive than other three methods in examination of all the antibodies. The lasting time of four techniques were: papain technique 45 min, anti-human globulin technique 60 min, polybrene test 5 min, and micro-column gel test 30 min. Conclusion Papain technique has some limitation in determination of IgG antibodies and anti-globulin technique is complicated because of long period incubation and multiple wash of red blood cells. Polybrene test is the most simple and convenient technique for determination of IgG antibodies. Micro-column gel test is the most sensitive method in determination of IgG antibodies.

RESUMO

To study the formation and change of platelet leucocyte aggregation (PLA) in red blood cell concentrations(CRCs) stored at 4℃ and the preventive effectiveness of filtration, 8 units of CRCs were each divided into two equal parts in two integrative bags and two paired groups were formed: control group and filtration group. The following items of control group and filtration group were detected weekly. Platelet and leukocyte counts, concentration and percentage of platelet lympocyte (P lym), platelet monocyte (P mon), platelet neutrophil (P neu) aggregatoins, and concentration of total PLA. The results showed that rate and concentration of PLA in the control group were significanly higher than those in the circulating blood. The rates of P lym and P mon in CRCs stored at 4 ℃ were two to five times of those before storage, and the rate of P neu in CRCs stored at 4 ℃ was ten to twenty times of that before storage. PLA in the CRCs separated from plasma rose to a high level at the first day of preparation. The concentration of PLA in CRCs reached the highest level at one week after stored at 4 ℃ and then decreased, but a high concentration was retained all the while. P neu is the major part (about 80%~90%) of whole PLA in CRCs. PLA was not detectable by flow cytometry during the whole storage course. The results suggested that high concentrated PLA was detected in CRCs stored at 4 ℃, which could be prevented by leucocyte depleting filtration.

RESUMO

Objective To establish the technique of loading trehalose into human platelets including temperature, time and concentration of trehalose loading. Methods Intracellular trehalose concentration versus loading time curves at 37℃ and 16℃, mean plateletee volume(MPV) versus loading time curves, and loading concentration curves were investigated and compared. Then loading time and temperature for high loading efficiency of trehalose into human platelets were ascertained. Intracellular trehalose versus trehalose loading concentration curves were made, and loading efficiency was caculated. Results The trehalose loading efficiency of 4 hours at 37℃ was significantly higher than that at 16℃ (11.6% vs 5.6%). MPV at 16℃ increased 43.2% compared with at 37℃, but had no changes along with the change of loading time and concentration. When loading at 37℃, MPV change was positively related with loading time and concentration, and loading time and loading concentration had a cooperative effect. MPV had no changes in 1~4hours loading when trehalose loading concentration was under 50mM. MPV increased with the increase of loading time and concentration when trehalose loading concentration was above 50mM. When trehalose loading concentration was 45mM, loading efficiency at 37℃ reached 13.86% 4 hours aftr loading. Conclusion The basic parameter of trehalose loading technique of human platelets was loading temperature at 37℃, loading time for 4 hours, and loading concentration of 45mM.

RESUMO

In order to explore the permissible range of temperatures for cryopreserved platelets, each of the eleven bags of platelets with 5% dimethyl sulfoxide was divided at random into eight aliquot paired groups labeled A, B, C, D, E, F, G, and H respectively. All of the groups were stored at -80℃ for one day. The control group A was stored at -80℃ throughout the experiment, and group B, C, D, E, F, G, H were replaced to the refrigerator at -80℃ after they were stored for 4 hours at -60℃, -50℃, -40℃, -30℃, -20℃, -10℃, and 0℃ respectively. All samples were thawed to test the phosphatidylserine expression, CD62p re expression, slide platelet aggregation test(SPAT), and activated plasma clotting test(aPCT). The above items were monitored in group A hourly when group A was thawed and stored at 22℃ for 4 hours. The results showed that the permissible storage temperature of cryopreserved platelet was under -40℃, and storage at temperature from -30℃ to 0℃ was detrimental for cryopreserved platelets. No significant damages were detected when the thawed platelets were stored at 22 with a gentle shaker.
