ABSTRACT
Objective :To explore influence of intra—arterial thrombolysis combined hyperbaric oxygen on serum levels of soluble intercellular adhesion molecule—1 (sICAM—1) and calcitonin gene related peptide (CGRP) in patients with severe ischemic stroke .Methods : A total of 96 patients with severe ischemic stroke in our hospital were randomly and equally divided into thrombolysis group and combined treatment group (received intra—arterial thrombolysis +hyperbaric oxygen therapy ).United States National Institutes of Health Stroke score (NIHSS) was used to assess neurological function recovery , and modified Rankin rating score (mRS) was used to assess recovery of clinical symptoms.After two—week treatment ,clinical therapeutic effect etc .were compared between two groups .Results :Compared with thrombolysis group after treatment ,there was significant rise in total effective rate (77.08% vs. 93. 75%, P＝0.021) ;significant reductions in scores of NIHSS [ (8.10 ± 3.45) scores vs .(5.36 ± 2.11) scores] and mRS [ (2.58 ± 0. 80) scores vs .(1.81 ± 0.76) scores] ;significant reduction in serum sICAM—1 level [ (237.31 ± 18. 04) ng／ml vs.(220.25 ± 16.40) ng／ml] ,and significant rise in serum CGRP level [ (27.02 ± 6.06) pg／ml vs. (35.24 ± 6.13) pg／ml] in combined treatment group , P＝0.001 all.There was no significant difference in revascu—larization within two weeks between two groups , P＝0.551. Conclusion : Intra—arterial thrombolysis combined hy—perbaric oxygen possesses significant therapeutic effect on patients with severe ischemic stroke .It can relieve clinical symptoms ,recover cognitive function ,improve revascularization rate in these patients .
ABSTRACT
Objective To investigate serological blood typing of the ABO locus which contradict to general law of inheritance in parentage,and the underlying reasons for severe hemolytic disease of newborn(HDN).Methods To research the family whose newborn is AB phenotypes,mother is O phenotypes and father is AB phenotypes.The familiy were genotyped by parentage tests, serological tests,PCR-SSP and direct DNA sequencing at exons 6 and 7 of ABO gene.At the salne time,HDN was detected by micro column gel Coombs (MGCT), and the primary fingerposts of the routine blood tests. Biochemical tests were dynamically observed.Results The results of parentage tests showed that three-generation pedigree have parent-child relationship. The red blood cell(RBC)of this AB phenotypes of this family members strongly agglutinated(4+)with diverse monoelonal anti-A and anti-B antibodies,and their serum did not contain anti-A and anti-B antibodies in blood anti-typing.PCR-SSP can not detect their A and B gene,but DNA sequencing at exons6 and 7 of ABO gene revealed that it had the B(A)803C→G mutation.Conclusions The genetm basis of this parentage are B(A)803G blood gene which harbored both A and B difunctionality of glyeosyhransferases.This was the first report that severe HDN resulting from a large number of A and B antigens in RBC of B(A)phenotype of a newborn,which has clinical significance on ABO locus.
ABSTRACT
OBJECTIVE:To optimize the preparation technology for enteric-coated changbiqing granules.METHODS:The concentration of acrylic resin and the four factors like the quantity of castor oil,pulvis talci and methylsilicone oil on the yield of changbiqing enteric-coated granules were determined by orthogonal test design;The effects of the enteric-coated granule plasticizer on the quantity of castor oil and the weight increment of the coating were determined by the release rate test.RESULTS:The optimized formula of the coating solution was described as follows:the concentration of acrylic resin was5%,the relative amount of castor oil to acrylic resin was35%,the dosages of pulvis talci and methylsilicone oil were3%and1%,respectively,the weight increment of the coating was30%.CONCLUSION:Changbiqing enteric-coated granules pre?pared on the optimized technology are in line with the quality requirements and which have ideal enteric soluble drug releasing characteristics.
ABSTRACT
Objective To observe the changes of the function of vascular endothelial secretion, levels of OX-LDL and body-weight of obese children after exercise intervention. Methods Thirty children with obesity at the age of 8 to 14 years and 30 normal children were enrolled in this experiment. The obese children (exercise group) received a session of 1 hour's exercise each day, 5 days a week for 8 weeks. The levels of ET, 6-K-PGF1?,NO, OX-LDL and body-weight were then measured and compared with that of their pre-exercise state and that of the normal children (control group). Results The levels of ET and OX-LDL were increased, while the levels of NO and 6-K-PGF1? were decreased in the obese children in comparison with the normal controls, the difference was statistically significant ( P
ABSTRACT
OBJECTIVE:To evaluate the situation of the use of cardiovascular drugs and its trend of develop?ment.METHODS:The cardiovascular drugs used during2001～2003were analyzed retrospectively in respect to the sale amount,DDDs and etc.RESULTS:The sale amount of cardiovascular drugs was increasing year by year;the antihypertensives and antianginals ranked at the first two places in respect to the sequence of the amount of money and the DDDs;the sale amount of joint-venture products was the largest,and there was a high proportions of national essential drugs consump?tion.CONCLUSIONS:There was a stable and rational structure of cardiovascular drugs in our hospital.Domestic substitute drugs should be exploited for medical researchers in the future so as to reduce the cost of medicine.
