ABSTRACT
ObjectiveTo discuss the correlation between young patients’ adverse transfusion reaction and pre-transfusion C reactive protein （CRP） level and EO% （percentage of eosinophils） . MethodsThe observation group was chosen from among sixty-six young patients who experienced transfusion-related adverse events between January 2019 and December 2020. For each patient chosen to be included in the observation group， another patient from the same department， with the same disease and gender， who had been hospitalized in the same month and received the same type of blood product transfusion， but had not experienced any transfusion-related adverse effects， was chosen to be in the control group. We examined and compared their ages， transfusion experiences， allergy backgrounds， EO%， and CRP levels in peripheral blood prior to transfusion. A receiver operating characteristic （ROC） curve was used to examine the diagnostic value of EO% and CRP for transfusion-related adverse events. Simultaneously， a logistic analysis was performed on the risk factors for transfusion-related adverse events. ResultsPre-transfusion CRP was higher in patients with FNHTR in the observation group than it was in patients in the control group； pre-transfusion CRP was also higher in patients with ATR in the observation group than it was in patients in the control group. There were also statistically significant differences between these variables in the percentage of patients with transfusion history and pre-transfusion EO% （ P＜0.05）. For the transfusion of different blood types， there was statistical significance in the occurrence of ATR and FNHTR （ P＜0.05）. For the diagnosis of FNHTR， the CRP area under the ROC curve was 0.889， and the best cut-off value was 18.05 mg/L. For the diagnosis of ATR， the area under the ROC curve was 0.749， and the best cut-off values were 17.60 mg/L. ConclusionPre-transfusion C-reactive protein level is an independent risk factor for FNHTR and ATR in young patients； the predictive value of EO% for adverse blood transfusion reactions is insufficient.
ABSTRACT
Objective:To optimize proportion of couplet medicine of Bupleuri Radix and Scutellariae Radix in the treatment of anti-depression, and to explore the possible antidepressant mechanism of this couplet medicine. Method:The dosages of Bupleuri Radix and Scutellariae Radix in the 2015 edition of Chinese Pharmacopoeia were taken.According to U7(72) uniform design table, Bupleuri Radix and Scutellariae Radix were carried out into 7 groups.The chronic unpredictable mild depression model mice were induced by intragastric administration of decoction of this couplet medicine and the antidepressant effect was observed by the behavior tests, which included sucrose preference test, tail suspension test, forced swimming test and open field test(crossing scores).The regression equations were established by selecting the effective indexes.The experiments of retest were taken to check the results and the possible antidepressant mechanism was primarily investigated by measuring the phosphorylation level of cyclic adenosine monophosphate(cAMP)-response element binding protein(CREB) and expression of brain-derived neurotrophic factor(BDNF). Result:Compared with the blank group, sucrose preference rate of the model group was significantly decreased(PPPPPPPPPPPPPPConclusion:Compatibility of Bupleuri Radix and Scutellariae Radix can ameliorate depressive-like behavior of model mice, and the best antidepressant compatibility proportion of Bupleuri Radix and Scutellariae Radix is 1:1, the optimal amounts of them are about 5 g.The antidepressant effect may relate to promoting phosphorylation level of CREB and the expression of BDNF in the hippocampus.
ABSTRACT
<p><b>BACKGROUND</b>Glutamic acid decarboxylase antibody (GADA) and protein tyrosine phosphatase antibody (IA-2A) are two major autoantibodies, which exert important roles in the process of type 1 diabetes mellitus (T1D). Our study aimed to investigate the changes in positivity and titers of GADA and IA-2A during the course of Chinese acute-onset T1D patients and their relationships with clinical features.</p><p><b>METHODS</b>Two hundreds and forty-seven Chinese newly diagnosed acute-onset T1D patients were consecutively recruited. GADA and IA-2A were detected at the time of diagnosis, one year later, 3-5 years later after diagnosis during the follow-up; all the clinical data were recorded and analyzed as well.</p><p><b>RESULTS</b>During the course of acute-onset T1D, the majority of patients remained stable for GADA or IA-2A, however, a few patients changed from positivity to negativity and fewer patients converted from negativity to positivity. The prevalence of GADA was 56.3% at diagnosis, decreasing to 50.5% one year later, and 43.3% 3-5 years later while the corresponding prevalence of IA-2A were 32.8%, 31.0% and 23.3%, respectively. The median GADA titers were 0.0825 at diagnosis, declining to 0.0585 one year later and 0.0383 3-5 years later (P < 0.001), while the corresponding median titers were 0.0016, 0.0010, 0.0014 for IA-2A, respectively. Fasting C-peptide (FCP) and postprandial C-peptide 2 hours (PCP2h) levels of GADA or IA-2A negativity persistence patients were higher than those of positivity persistence and negativity conversion patients (P < 0.05) which indicated GADA or IA-2A negativity persistence T1D patients had a less loss of β cell function.</p><p><b>CONCLUSION</b>Our data suggest that repeated detection of GADA and IA-2A are necessary for differential diagnosis of autoimmune diabetes and the indirect prediction of the β cell function in Chinese patients.</p>
