OBJECTIVETo explore the correlation between the recurrence of cerebral infarction and aspirin resistance (AR)/Chinese medical (CM) constitutions.

METHODSTotally 413 cerebral infarction patients took Aspirin Enteric-coated Tablet (100 mg per day) while receiving routine therapy, 5 days at least in a week. They were followed-up for 12 months. Aspirin sensitivity (AS) was determined using turbidimetry. CM constitutions among patients with different AS were compared. Ratios of AR patients and AS patients of different CM constitutions in cerebral infarction recurrent patients were compared. Platelet membrane glycoproteins (GP) II b HPA-3 gene polymorphism was detected by polymerase chain reaction (PCR) method. Correlation between recurrence of cerebral infarction and AR, bb genotypes, CM constitutions times AS were analyzed by Logistic regression.

RESULTSTotally 11 patients dropped out, 101 (25.12%)with recurrent cerebral infarction and 301 (74.88%) without recurrent cerebral infarction. There were 152 (37.81%) AR patients and 250 (62.19%) AS patients. AR accounted for 26.6% (80/ 301) and AS accounted for 73.4% (221/301) in non-recurrent cerebral infarction patients. AR accounted for 71.3% (72/101) and AS accounted for 28.7% (29/101) in recurrent cerebral infarction patients. There was statistical difference in AR and AS ratios (χ2 = 64.287, P = 0.000). The proportion of yin deficiency constitution (YDC) was the largest [28.3% (43/152)] in AR patients. The proportion of blood stasis constitution (BSC) was the largest [23.6% (59/250)] in AS patients. There was statistical difference in CM constitutions between AR patients and AS patients (χ2 = 21.574, P < 0.01). The former 4 recurrent rates occurred in AR patients of YDC, BSC, damp-phlegm constitution (DPC), qi deficiency constitution (QDC). YDC occupied the first place [22.4% (34/152)]. The former 4 recurrent rates occurred in AS patients of BSC, QDC, DPC, damp-heat constitution (DHC). BSC occupied the first place [3.2% (2/250)]. Compared with non-recurrent cerebral infarction patients and AS patients, bb gene occurred most often, but aa gene and ab gene occurred obviously lesser in non-recurrent cerebral infarction patients and AR patients (χ2 = 20.171, χ2 = 55.139, P < 0.01). AR and bb gene were positively correlated with recurrent cerebral infarction (OR = 18.423, P = 0.000; OR = 1.304, P = 0.028). Body constitutions interacted with AS (OR = 0.707, P = 0.000).

CONCLUSIONSRecurrent cerebral infarction was closely related to AR and constitutional types. The recurrence rate was higher in AR patients of YDC. GP I b HPA-3 bb genotype might be a risk factor for AR and recurrent cerebral infarction.

Objective To analyze changes of three periodical circulation systems,erythrocyte sedimentation rate and bone marrow cell morphology in children with malaria.Methods The routine tests of hematology by Sysmex KX-21 Counter, erythrocyte sedimentation rate by Westergren method and bone marrow cell morphology were analyzed. Results In 22 cases of malaria the ratio of Hb level below 110 g/L,WBC below 4?10~9/L and PLT below 100?10~9/L was 68.2%, 41.0%, and 77.3%,respectively. The ratio of children with all three parameters (Hb, WBC and PLT) abnormal was 36.4%, with two parameters abnormal was 63.6%. Ninty-five point five percent of malaria children′s erythrocyte sedimentation rate was abnormal. Fifty-nine point one percent of malaria children had hyperplasia anemia bone marrow morphology, 77.3% secondary thrombocytopenia and 54.5% with both of two bone marrow morphology.Conclusions Three periodical circulation systems of malaria children alter notably, especially in PLT and Hb. The majority has erythrocyte sedimentation rate abnormal, and bone marrow cell morphology shows hyperplasia anemia and thrombocytopenia.

OBJECTIVETo study the effect of a low level of galacto-oligosaccharides (GOS) on intestinal bifidobacteria and lactobacilli, and fermentation characteristics in term infants by comparing with human milk and a standard infant formula without GOS.

METHODSA total of 371 term infants from four hospitals of China were enrolled. The infants started with breast feeding. After 1-2 weeks, some of the infants were changed to feeding with formula milk and then were randomly assigned to two formula-feeding groups: with or without GOS supplementation (2.4 g/L). Growth, stool characteristics, and side effects were recorded in a 3-month-follow-up. Faecal samples were collected for analysis of intestinal bacteria (culture technique), acetic acid (gas chromatography) and pH (indicator strip) at postnatal 3 months.

RESULTSCompared with the formula-feeding group without GOS, the contents of bifidobacteria, lactobacilli and acetic acid and stool frequency increased, and faecal pH decreased significantly in the GOS-formula-feeding and the human milk group. There were no significant differences between the GOS-formula-feeding and the human milk groups. Supplementation with GOS did not lead to an increase in the incidence of crying, regurgitation and vomiting.

CONCLUSIONSA supplementation of low levels of GOS in infant formula seemed to improve stool frequency, decrease faecal pH, and stimulate intestinal bifidobacteria and lactobacilli up to levels as found in breast-fed infants.

OBJECTIVETo explore if early fracture fixation can alleviate gut barrier function damage caused by multiple firearm injuries in pigs.

METHODSTwelve healthy pigs were subjected to tangential fracture of parietal bone and comminuted fractures of bilateral femora (ISS >or= 16) due to 5.8 mm bullets shooting and these pigs were divided randomly into 2 groups. Control group (n = 6) were not treated at all. Fracture fixation Group (n = 6) were managed by immediate fracture fixation of bilateral femora with intramedullary nails. Plasma concentration of D-lactate, DAO and endotoxin (in portal vein) were detected at different intervals before and after trauma. The portal vein blood was cultured and the percentage of positive isolation was calculated. The concentration of DAO in small bowel was also detected 72 hours later after trauma.

RESULTSIn control group, the plasma concentrations of D-lactate, DAO and endotoxin increased at early stage and kept high till 72 hours after trauma; the percentage of positive blood culture was 63.3%. In Group F, the levels of plasma D-lactate, DAO and endotoxin were also elevated at early stage (6 - 12 h), but declined significantly from 24 h or 48 h after trauma compared with control group (P < 0.05), and the percentage of positive blood culture was lower (30.0%, P < 0.05). The concentrations of DAO in small bowel decreased in both groups, but to a less extent in Group F.

CONCLUSIONBacterial and endotoxin translocation emerged with increasing gut permeability after multiple firearm injuries. The damage of gut barrier function could be alleviated and the chance of enterogenous infection could be by early fracture fixation after trauma.

OBJECTIVETo investigate the pharmacokinetic and distribution character of scutellarin in plasma and tissues in rats, in order to provide some references for rational drug use in the clinic.

METHODThe solution of scutellarin was administered to rats (80 mg x kg(-1)) by oral gavage. A high performance liquid chromatography method determinated the scutellarin concentration in rat plasma and tissue. The plasma samples were performed by solid phase extraction method. The other biological samples were extracted by ethyl acetate.

RESULTThe range of scutellarin in plasma and tissue in rats were 10-1280 ng x mL(-1) (R2 > 0.99), 40-1280 ng x g(-1) (R2 > 0.99), respectively. The lowest detection of scutellarin were 10 ng x mL(-1) and 40 ng x g(-1), the precision were less than 8%. The main pharmacokinetic parameters of scutellarin were as follows: tmax, Cmax, AUC and MRT being (7.7 +/- 0.9) h, (288.0 +/- 75.2) microg x L(-1), (5.6 +/- 1.6) microg x mL(-1) x h(-1), (17.5 +/- 1.4) h(-1), respectively.

CONCLUSIONThese methods applied the study of pharmacokinetics of scutellarin. After oral the scutellarin in rats, the concentration-time course doesn't obey any compartment model. The concentration-time curve is the double peaks.

OBJECTIVETo study the linkage between -148C/T polymorphism of beta-fibrinogen gene and plasma fibrinogen levels in patients with acute cerebral infarction.

METHODSOne hundred and fifty-one patients with cerebral infarction and 101 healthy individuals were enrolled in this trial. The beta-fibrinogen gene -148C/T polymorphism was analyzed by PCR-restriction fragment length polymorphism, and plasma fibrinogen levels were obtained from prothrombin time assay.

RESULTSPlasma fibrinogen levels of patients were significantly higher than those of controls (P<0.01). In both groups, T allele carriers had higher plasma fibrinogen levels than other those did (P<0.01); and the fibrinogen level difference was still significant if both groups was based on their sex (P<0.05). Divided by age, each group of the study cases has significant difference between two genotypes (P<0.05). T -148 allele frequency of the middle age case in study group was higher than that in control group (P<0.05).

CONCLUSIONHigh plasma fibrinogen level is a risk factor to cerebral infarction. Plasma fibrinogen level is affected by -148C/T polymorphism of beta-fibrinogen gene. With or without other risk factors and environmental factors affecting, T allele increases plasma fibrinogen level and may be a heritable risk factor to cerebral infarction.
