ABSTRACT
Objective To investigate the clinical significance of plasma prothrombin activity (PTA) and serum alpha fetoprotein (AFP), prealbumin (PALB) in severe hepatitis patients treated with artificial liver plasma exchange. Methods The clinical data of 31 patients with severe hepatitis were retrospectively analyzed. The patients were treated with artificial liver plasma exchange based on the comprehensive treatment. The patients were divided into survival group (17 cases) and death group (14 cases) according to the clinical outcome. The plasma prothrombin time (PT) and serum AFP, PALB levels were detected before treatment, 3rd, 9th and 18th day after treatment and at the last time (prior to discharge/ in extrimis), and the PTA was counted. Results There was no statistical difference in PTA before treatment and 3rd day after treatment between 2 groups (P>0.05). The PTA levels 9th and 18th day after treatment and at the last time in death group were significantly lower than those in survival group:(30.17 ± 4.79)％vs. (39.74 ± 4.77)％, (25.47 ± 6.46)％vs. (42.79 ± 6.88)％and (21.40 ± 9.17)％vs. (47.17 ± 5.46)％,and there were statistical differences (P0.05);the AFP levels 3rd, 9th and 18th day after treatment and at the last time in death group were significantly lower than those in survival group:(121.9 ± 31.7)μg/L vs. (134.6 ± 31.8)μg/L, (88.7 ± 40.8)μg/L vs. (169.9 ± 41.7)μg/L, (56.9 ± 29.7)μg/L vs. (176.8 ± 48.1)μg/L and (29.8 ± 15.7) μg/L vs. (204.3 ± 41.2) μg/L, and there were statistical differences (P0.05); the PALB levels 3rd, 9th and 18th day after treatment and at the last time in death group were significantly lower than those in survival group: (107.2 ± 17.4) mg/L vs. (126.3 ± 33.2) mg/L, (91.2 ± 11.9) mg/L vs. (137.9 ± 35.7) mg/L, (54.7 ± 14.8) mg/L vs. (151.9 ± 27.9) mg/L and (43.3 ± 19.7) mg/L vs. (159.3 ± 41.2) mg/L, and there were statistical differences (P<0.05). Conclusions The plasma PTA and serum AFP, PALB levels are closely related with curative effect of artificial liver plasma exchange in severe hepatitis patients, and dynamic observation of its changes can help to determine the condition.
ABSTRACT
Objective To investigate the methods and internal quality control ( IQC ) leucorrhea routine examinationin clinical laboratories of medical institutions in Guizhou Province.Methods In 2009, 97 clinical laboratories were randomly selected for the first investigation.At the same time, staffs in theinvestigated laboratories were educated on the importance of IQC.The second investigation of the same items was carried out in 2011 inthe same laboratories.The results of the two investigations were analyzed byChi-square test.Results 2009 and 2011 numbers of laboratories thoseonly used normal saline suspension method for leucorrhea examination were 17and 16 (χ2 =0.037, P >0.05 ) respectively, used bothnormal saline and 10%KOH suspension methodswere 16and 2(χ2 =12.003,P<0.01), used staining method were 64and 79(χ2 =5.488,P<0.05), both used suspension and staining methods were 60and 73(χ2 =4.041, P<0.05), used normal salinesuspension method combined with Wright stain and Gram staining methods were3and 28(χ2 =23.996,P<0.01) respectively.Numbers of Laboratoriespracticing IQC were 2and 88in 2009 and 2011 respectivly(χ2 =153.293,P <0.01).Conclusions Currently, the most common used method for leucorrhea routine examination is suspension.Through the investigations and education, the quality ofleucorrhea routine examination was improved in Guizhou Province.
