ABSTRACT
【Objective】 To study the effect of regular blood donation on the serum iron (SI) and serum ferritin (SF) of regular blood donors. 【Methods】 A total of 240 blood samples (4~5 mL per person, with EDTA-2K anticoagulant) from regular voluntary blood donors in our center from January to June 2019 were randomly selected as the study group. Another 200 healthy subjects without blood donation history were randomly selected as the control group. SI was measured by Ferene method, SF by chemiluminescence method, and blood routine indexes by automatic hematology analyzer. 【Results】 The Hb, RBC count, HCT and other blood routine indexes of the study group and the control group were all in the normal range. SI (mol/L) in the study gourp and the control group was 17.13±4.36 vs 17.82±5.78(P>0.05), and SF (ng/mL) was 98.34±52.74 vs 147.52±91.52 (P<0.05). 【Conclusion】 SI and SF may decrease due to regular blood donation, which deserve close follow-up to ensure the safety of regular blood donors.
ABSTRACT
Objective:To observe the intervention effect of acarbose on cerebral arterial thrombosis complicated with impaired glu-cose tolerance(IGT).Methods: Totally 120 cases of IGT patients with ischemic stroke were randomly divided into the observation group (58 cases) and the control group(62 cases). The two groups were given the same basic treatment,while the observation group was treated with acarbose 50 mg,po,tid for 3 months additionally. Before and after the treatment,the levels of blood lipid and blood glucose,serum high-sensitivity C reactive protein(hsCRP) and carotid intima media thickness(IMT) and the other adverse drug reac-tions were detected in the two groups. After 6-month follow-up,the new incidence of IGT was compared between the groups.Results:After the treatment,2 hPG,HbAlc,hsCRP and the other indicators in the observation group were significantly improved when com-pared with those before the treatment(P<0.01 or P<0.05),while only hsCRP in the control group was significantly improved when compared with that before the treatment(P<0.05) and that in the observation group. 2 hPG,HbAlc,hsCRP,IMT and the other in-dicators in the observation group were significantly better than those in the control group(P<0.01 or P<0.05). There was no signifi-cant change in the level of blood lipid in the two groups. There was no adverse drug reaction during the treatment. After the 6-month follow-up,the new incidence of IGT in the observation group was 1.82%,which was significantly lower than that in the control group (7.27%,P<0.05).Conclusion: Among the patients with cerebral arterial thrombosis complicated with impaired glucose tolerance, the normal treatment measures plus acarbose can effectively delay carotid artery IMT incrassation and decrease the risk of cardiovascular events recurrence with better relative safety.
ABSTRACT
Objective To understand and to grasp the basic situation on blood donors who were ineligible by ALT dry chemistry testing before blood donation.Methods The ALT rejection ratios used in initial screening and not used in two blood collection point were compared at the same time.The relativity between the dry chemistry testing and rate method were compared.An association was explored in various influencing factors on the activity of ALT.Results The use of ALT initial screening in blood donation had a significantly lower unqualified rate than not using it in early screening (P＜0.05).Dry chemical,biological method and the results had good correlation rates (r=0.993,P＜0.05).The B MI,drinking,sleeping,sports,diabetes,liver disease were independent factors affecting ALT activity (P＜0.05).Conclusion ALT initial screening can significantly reduce the unqualified rates and disposal of blood.
ABSTRACT
[Objective] To study the mechanism of Ruangan Granule (RG) in counteracting the experimental liver fibrosis and cirrhosis in SD rats. [Methods] As compared with colchicines, effect of RG in small and large dosages on serum transforming growth factor ? (TGF ?1 ), hydroxyproline (Hyp), collagen Ⅰ and Ⅲ , hepatic function and hepatic pathology were observed in rats. [ Results ] Both RG and colchicines could decrease serum levels of alanine aminotransferase (ALT) and alkaline phosphatase (AKP) and increase serum levels of total protein and albumin in rats with liver fibrosis induced by bovine serum albumin (P 0.05). Effect of large-dosage RG in improving hepatic pathology was better than that of colchicines. [Conclusion] RG has an inhibitory effect on the formation of liver fibrosis and cirrhosis. Its mechanism may be related to the improvement of hepatic function, decrease of serum TGF ft , collagen Ⅰ and Ⅲ and Hyp levels.
