Objective To investigate the recent prognosis of stress hyperglycemia for the emergency percuta- neous coronary intervention(PCI)with ST-segment elevation acute myocardial infarction(AMI).Methods 410 pa- tients treated by emergency PCI were chosen.According to a history of diabetes and blood glucose levels,they were randomly divided into four groups:group 1(n = 288):random blood glucose normal and non-diabetic patients;group 2(n = 30):random normal blood glucose in diabetic patients;group 3(n = 54):random plasma glucose level and non- diabetic patients;group 4(n = 38):high random plasma glucose level in diabetic patients.Age,gender,hospital within 24 hours with random glucose,glycated hemoglobin(HbA1c),peak creatine kinase,TIMI flow recovery and 30-day mortality of the patients were compared.Results Mortality of four groups were 4.2%,3.4%,7.5% and 5.9% re- spectively(P

Objective To investigate the effects of supplementing qi and activating blood circulation method(YQHX) on platelet inhibition rate and platelet membrane glycoprotein in elderly patients with unstable angina pectoris undergoing percutaneous coronary intervention(PCI).Methods Totally 177 elderly patients with unstable angina(qi deficiency and blood stasis syndrome) pectoris were randomized into two groups:90 cases in the treatment group and 87 cases in the control group.Both groups received conventional western medicinal treatment,for 14 days but YQHX was added to the treatment group.Platelet inhibition rate and platelet membrane glycoprotein were measured before and 14 days after treatment.Results After 14 days of treatment,the platelet inhibition rates induced by arachidonic acid (AA) and adenosine diphosphate (ADP) were significantly increased in the treatment group in comparison to pre-treatment and to control group respectively(P＜0.01).The prevalence of aspirin and clopidogrel resistance were lower in the treatment group than in the control group(8.9％ vs.21.8％,11.1％ vs.25.3％,both P＜0.05).After 14 days of treatment,the expression rates of CD62p,CD63 and PAC-1 were significantly lower in the treatment group than in pre-treatment and control group respectively (P＜0.01).Conclusions YQHX might effectively inhibit the platelet function and reduce the prevalence of aspirin and clopidogrel resistance in elderly patients with unstable angina pectoris undergoing the percutaneous coronary intervention.

Objective To observe the clinical effectiveness and prognostic factors of autologous hemopoietie stem cell transplantation on diabetic peripheral angiopathy patients under different degrees of vascular lesions. Methods Thirty-six patients with diabetic were divided into mild vascular stenosis group (group A: 20 lower extremities, vascular stenosis less than 50% ), moderate vascular stenosis group(group B :26 lower extremities, vascular stenosis of 50%-70% ) and severe vascular stenosis group (group C: 25 lower extremities, vascular stenosis greater than 70% ) according to the degree of vascular lesions. All patients were given the stem cell mobilization for 5 days, then peripheral hemopoietic stem cells were gathered on the last day and transplanted to ischemic limb by using monoeyte stem cell suspend liquid with 3 cm × 3 cm intervals.Each index of three groups was regularly observed ( 1th,12th and 18th month respectively after the operation)and comprehensive evaluated. Meanwhile,the transplantation prognostic factors (age, disease duration, post-prandial 2 hours blood glucose, glycated hemoglobin, blood pressure, triglycerides) were analyzed by multiple regression. Results Twelve months after transplantation, the ankle brachial index (ABI) and percutaneous oxygen pressure (TcPO2) of all three groups increased compared with that before the transplantation (P<0.05). In the 18th month after transplantation, the ABI still increased in group A and B (P< 0.05), and no significant changes were found in group C compared with that in the 12th month. Eighteenth month after transplantation, lower extremities of 8 patients (40%) in group A, 8 patients (31%) in group B and 6 patients (24%) in group C were examined to have neovascularizatian. Age, disease duration, blood pressure, post-prandial 2 hours blood glucose, glycated hemoglobin and triglycerides were all the important factors that affected diabetic peripheral angiopathy recurrence after transplantation. Conclusions The long-term effica-cy of stem cell transplantation on diabetic peripheral angiopathy patients at a mild to moderate degree is superior to that with severe vascular lesions. Close monitoring of blood glucose, blood pressure and triglycerides in the operation perinatal stage is required.They are the important prognostic indicators.

Objective To evaluate the effect of various sampling errors on ELISA test results. Methods Standard sample volume,standard sample volume reducing 1,2,3,4 μL or adding 1, 2,3 μL were respectively pipetted into the wells of a microplate,follwed by routine operation of ELISA test. Then the influence of various sampling errors was analyzed on ELISA test results of HBsAg, HCV and TP. Results S/CO value was increased with the increase of sample volume. The statistical difference of mean S/CO value of HBsAg and TP was only found between sample volume adding 3 μL group and control group(P<0.05). For HCV result, there were significant differences between standard sample volume adding 2,3μL or reducing 3,4μL groups and control group(P<0.05), while no obvious differences were found in the other groups(P>0.05). The difference of mean positive rate between ex-perimental groups and control group showed an increasing tendency with the reduction of sample vol-ume,and significant differences in HBsAg, HCV and TP results were also found between sample vol-ume increase groups and reduction groups(P<0.05). Conclusion Various sampling errors influence ELISA test results to different degrees,and the extent increases with the reduction of standard sample volume.

Objective To investigate the influence of coix seed triglyceride combined with transcatheter arterial chemoembolization (TACE) therapy on AFP, CD4﹢CD25﹢regulatory T (Treg) cells and cellular immune function in patients with advanced primary hepatocellular carcinoma (HCC). Methods A total of 50 patients with inoperable HCC, whose imaging examination showed no distant metastasis, were divided into the study group (n=25) and the control group (n=25). Coix seed triglyceride together with TACE was employed for the patients of the study group, while only TACE was adopted for the patients of the control group. For the patients of the study group, transcatheter hepatic artery infusion of 100 ml coix seed triglyceride was carried out during the performance of TACE, and postoperative intravenous drip of coix seed triglyceride (200 ml/d) was used for 5 days. The peripheral blood samples were collected one week before and one month after the treatment to detect the changes of AFP and T lymphocyte subsets (CD3﹢, CD4﹢, CD8﹢,CD4﹢/CD8﹢ and Treg) levels. One month after the treatment, enhanced CT, MRI or PET-CT was performed to evaluate the necrosis degree of the tumor. Results After the treatment, AFP levels was decreased in both groups, when compared the preoperative data the differences were statistically significant (P<0.01); the tumor necrosis rate of the study group was (57.7 ±8.2)%, which was slightly higher than (57.7±8.2)% of the control group, however, the difference was not statistically significant (P>0.05). In the study group, the percentage of Treg cells decreased from preoperative (8.27±6.65)%to postoperative (4.22± 1.59)%, the difference was statistically significant (P<0.01). The percentages of CD3﹢ and CD4﹢ and the ratio of CD4﹢/CD8﹢ increased from preoperative (55.78 ±13.66)%, (43.98 ±14.00)% and 1.22 ±0.64 to postoperative (62.29±10.78)%(P<0.01),(51.82±16.32)% (P<0.05) and 1.54±0.80 (P<0.05) respectively, while the percentage of CD8﹢decreased from preoperative (45.71±12.94)%to postoperative (39.70±12.41)%(P<0.05). In the control group, no statistically significant differences in the above mentioned indexes existed between preoperative data and postoperative ones (P>0.05). Conclusion In treating advanced primary HCC, coix seed triglyceride combined with TACE can reduce the percentage of Treg cells, thus, influence the patient’s cellular immune status and possibly decrease the recurrence rate of HCC after TACE therapy.

Objective To monitor the function of infection on myelination in white matter damage,neonatal Wistar rats of postnatal day 2 (P2) and postnatal day 7 (P7) were injected intraperitoneally with the same doses of lipopolysaccharides (LPS),and 2',3 '-cyclic nucleotide phosphodiesterase (CNPase) and myelin basic protein (MBP) were labeled in immature oligodendrocytes and mature oligodendrocytes.To investigate the function of tumor necrosis factor(TNF)-α according to test the change of TNF-α expression in the brain.Methods Ninty-six neonatal Wistar rats were randomly divided into four groups (each group 24 rats):group A:LPS (5.0 mg/kg) was injected intraperitoneally on P2 ; group B:LPS (5.0 mg/kg) was injected intraperitoneally on P7 ;group C1 and C2 were control groups in which equal amount of normal saline was injected intraperitoneally on P2 or P7.The expression of CNPase at 24 h after injection and MBP at P14 in brain tissue of each group were measured by immunohistochemistry and express of TNF-α mRNA at 4 h after the injection was measured by RT-PCR.Results Punctate hemorrhage in the corpus callosum,external capsule and intraventricular hemorrhage were seen in group A.Periventricular leukomalacia appeared in the corpus callosum and glial cells hyperplasia could be seen periventricular in P14 rat brains,but not found in the group B and any of the saline-injected rat brains.Compared with group C1 and C2 respectively,CNPase-positive cells showed obvious decrease in the area of white matter in periventricular in group A(106.93 ± 2.62 vs 113.67 ± 2.69,P ＜ 0.01) and group B (96.37 ± 1.82 vs 101.65 ± 2.01,P ＜ 0.01).Following LPS treatment in group A,the protein expression of MBP in neonatal brain decreased evidently compared with group C1 at P14 (128.21 ± 2.99 v s 134.81 ± 2.98,P ＜ 0.01),while no significant change was found between group B and group C2(134.77 ±3.68 vs 134.81 ±2.98,P ＞0.05).After 4h of the LPS treatment,the level of TNF-α mRNA was greatly increased in group A,it was significantly higher than that in group B (1.79 ± 0.04 vs 1.18 ± 0.04,P ＜ 0.01).Conclusion Intraperitoneal injection of LPS to the development neonatal rats can lead to dysmyelination and white matter damage.The expression of TNF-oα mRNA increased significantly in these immature neonatal rats,while only myelination delay occurred in those of mature neonatal rats without dysmyelination.

Objective To investigate whether routine exposure recurrent laryngeal nerves(RLN) during the procedure of thyreoidectomy would prevent permanent nerves injuries caused by thyroid surgery.Methods 1523 patients with thyroid disease underwent thyreoidectomy from January 1980 to December 2004.Routine exposure of RLN during the procedure of thyreoidectomy were in 274 cases(group 1) and not in 1249 cases(group 2),the incidence rates of temporary RLN injuries and permanent RLN injures were compared in these groups.Results 3 cases(3/274,1.1%) occurred permanent RLN injuries in group 1 and 47 cases(47/1249,3.8%) occurred RLN injuries in group 2.The incidence rate of permanent RLN injuries in group 1 was lower than that in group 2(P0.05) in these groups.Conclusion Exposure recurrent RLN during the procedure of thyreoidectomy can effectively prevent permanent nerves injuries caused by thyroid surgery.

Objective To investigate the inhibition of low-dose aprotinin on systematic inflammatory response during cardiopulmonary bypass. Methods Twenty-eight ASA Ⅱ-Ⅲ patients(male 13, female 15) undergoing valve replacement were studied. The age ranged from 27 to 55 years and body weight from 37 to 70 kg. CPB time ranged from 66 to 218 mm and aortic cross clamping time from 30 to 140 min . The patients were divided into two groups: control group(n=14) and aprotinin group(n = 14) Premedication included intramuscular phenobarbital sodium 0.1 g and scopolamine 0.3 mg. Anesthesia was induced with intravenous midazolam 0. lmg/kg, fentanyl 20-30?g/kg and vecuronium 0. 1-0. 12mg/kg, and maintained with intermittent bolus injection of fentanyl and vecuronium supplemented with isoflurane inhalation. In aprotinin group aprotinin 1?106KIU was infused after induction of anesthesia until thoracotomy, after thoracotomy aprotinin was infused at a rate of 2.5? 106 KIU/h and aprotinin 2. 5 ?106KIU was added to the prime fluid as suggested by Levy. Blood samples were obtained before anesthesia, before CPB and 1h and 24h after CPB for determination of CD11b and CD18 expression on the surface of neutrophil by immunofluoresence flow cytometry. Results The expression of CD11b or CD18 and CPB time were positively correlated(?= 0.644, 0.538, P0.05). 1 h after CPB CD11b/ CD18 expression increased significantly in the control group and was significantly higher than that in the aprotinin group, but at 24h after CPB only CD11b expression in control group was significantly higher than that in aprotinin group. In aprotinin group there was no significant difference in CD11b/CD18 expression between the four intervals.Conclusions CPB-induced systematic inflammatory response may be positively correlated with CPB time. Low dose aprotinin can inhibit the increase in CD11b/CD18 expression after CPB.
