Results Survival of the donor heart was significantly prolonged and pathologic lesion was relieved, the contents of IL 2 and IFN ? in peripheral blood, percentage of CD3 +, CD4 +, CD8 + lymphocytes and ratio of CD4 +/CD8 + were significantly reduced in EEPCW groups.Conclusion Acute rejection of heart transplantation can be effectively suppressed by ethanol extract of poria cocos wolf.

Methaqualone and 2-methyl-3 [2- (hydroxymethyl) phenyl]- 4 (3H) quinazolinone (metabolite I) concentrations in human serum wereanalyzed quantitatively by reverse high performance liquid chromatography (RP-HPLC). The concentrations of methaqualone ranging from 1-35?g/ml were in good linear relationship(Correlation coefficient r = 0. 9980, regression line y = 0. 06324x-0. 1029), The average recovery of methaqualone reached as high as 102.08?9. 987(SD)% (n= 5). The detective limit was 1 ng. The relative quantity of metabolite I was determined according to the linear concentration of methaqulone. RP-HPLC assay is proved to be useful in determening blood methaqualone and metabolite I concentrations in forensic toxicology.

Objective To study the isolation and phenotype of peripheral blood pDC 1 and pDC 2 in rhesus monkey.Methods Peripheral blood monoclear cells (PBMCs) were isolated from healthy, SIV-negative rhesus monkeys (M.mulatta) using Ficoll-Hypaque density separation. DC precursors were identified and were sorted by 3 color rare-event cytometric flow analysis using human monoclonal antibodies cross reactive with rhesus monkey. Results DC subsets were identified within the lineage- HLA-DR+ fraction of PBMCs and maintained activities. Myeloid DC (pDC 1) showed the phenotype lineage-, HLA-DR+ and BDCA 1+; Lymphoid DC (pDC 2)showed the phenotype lineage-, HLA-DR+ and CD123+ (IL-3R?+).Conclusions We have identified the rhesus monkey pDC 1 and pDC 2 similar to those from human beings. Identification of pDC 1 and pDC 2 is an important first step towards testing of these important immunomodulatory APC in the therapy of allograft rejection in non-human primates.

Objective To investigate the effects of perfusion pressure with a cardioplegic solution on endothelium-dependent relaxation and smooth muscle function of porcine coronary artery. Methods The hearts were infused with a modified St.Thomas’ hospital solution at the pressures of 40, 60 and 80 mmHg. The distal part of porcine left anterior descending coronary artery (LAD) having a diameter of 1.0-1.5 mm, was dissected free from the surrounding tissue, cut into 1 mm long segments, immediately transferred to organ baths for the evaluation of endothelial and smooth muscle function. Results Smooth muscle function was not affected after cardioplegic flushing at the pressures used in this study. The maximal endothelium-dependent relaxations of the vessels in 40 and 60 mmHg groups were not reduced compared to fresh segments . The maximal EDR was significantly reduced to (90.8?2.2)% (P

Objective: To observe the clinical effect of oral nutrition supplementation for maxillofacial tumor patients before operation. Methods: 60 patients who suffered from maxillofacial neoplasm were divided into two groups. In observation group, on basis of routine diet, oral nutrition supplements (Fortisip) had been added for 5～7 days before operation. In control group, only routine diet had been supplied. After operation, the two groups were all supplied with tube feeding. The blood routine test, plasma total protein, albumin, pre albumin and lymphocyte count were measured in all patients. Results: Every biochemical item reduced significantly after operation and no statistical significance was found between groups. But the absolute decreasing values had significant difference between the groups. Conclusions: Oral nutrition supplements (Fortisip) contains balanced nutrients and tastes well. It is safe and effective to use a nutritional supplement, being helpful to prevent malnutrition and to improve the immune function in perioperative period of patients with maxillofacial neoplasm.

Objective To investigate the clinical significance of monitoring blood glucose in term infants with asphyxia. Methods The blood glucouse within 24 hours of admission and prognosis were retrospectively analyzed in full-term neonates with asphyxia admitted from January, 2011 to December, 2012. Results Among 256 term infants with asphyxia, 95 cases (37.11%) had abnormal blood glucose, 63 cases (24.61%) were hypoglycemia and 32 (12.50%) were hyperglycemia. The incidence of mild asphyxia and severe asphyxia, the number of damaged organ were significantly different among infants with hypoglycemia, normal blood glucose, and hyperglycemia (all P<0.001). Among 256 term infants, 206 cases were mild asphyxia, 50 cases were serve asphyxia. The incidence of abnormal blood glucose and hyperglycemia were significantly higher in infants with serve asphyxia than those in infants with mild asphyxia (P<0.01). Among 256 term infants, 227 cases (88.67%) had organ damaged. 96 cases involved one organ, 72 cases involved two organs, and 59 cases involved three or more organs. The incidence of abnormal blood glucose, hypoglycemia, hyperglucemia were significantly different among infants invoved one, two or threr and more organs. The incidence of hyperglycemia was the highest in infants with three or more organ damaged, and the incidence of hypoglycemia was the highest in infants with two organ damaged. Conclusions The term infants with severe asphyxia and more organ damaged were prone to with abnormal blood glucose.

Objective To evaluate the effect of pronase on amoxicillin and metronidazole concentrations in gastric tissue. Methods C57BL/6 mice were randomly divided into experimental group ( n = 70 ) and control group ( n = 70 ) . Amoxicillin ( 28. 6 mg/kg ) , metronidazole ( 22. 5 mg/kg) and omeprazole (138.2 mg/kg) were administered orally to C57BL/6 mice, combined with pronase (110 mg/kg) or same amount of sterile PBS. Gastric tissue and blood plasma samples were taken at 10 point-in time (7 mice/time) from 15 min up to 360 min after administration. Concentrations of amoxicillin and metronidazole were detected by high performance liquid chromatography. Gastritis index of gastric mucosa ( hematoxylin-eosin staining) and the gastric tissue expressions of mucin 5 AC (Western blot) were detected at 120 min and 360 min after administration. Results The time to peak concentration of amoxicillin and metronidazole in gastric tissue appeared earlier than that in blood plasma (15 min vs 60 min). Tissue concentrations of amoxicillin and metronidazole of experimental group were significantly higher than those of control, and they were mainly at 15 min to 90 min (P ＜0. 05). Plasma concentrations of amoxicillin and metronidazole of experimental group at 15 min and 30 min were higher than those of control ( P ＜ 0. 05 ). There was no difference in gastritis index between experimental group and control at 120 min and 360 min after administration (0.28±0. 18 vs 0. 14 ±0. 14,P＞0.05; 0. 43 ±0. 20 vs 0. 28 ±0. 18,P ＞0. 05). The expressions of mucin 5 AC in experimental group were lower than those of control ( 0. 036 ± 0. 006 vs 0. 197 ± 0. 058; P ＜0. 05; 0. 039 ± 0. 008 vs 0. 208 ± 0. 072, P ＜ 0. 05 ). Conclusions Pronase can significantly enhance the drugs penetration from mucus into gastric tissue. Concentrations of amoxicillin and metronidazole of experimental group in local gastric tissue and plasma are higher than those of control, especially in improving concentrations of gastric tissue and prolongation of exposed time.

Objective To investigate the relationship between serum 25-(OH) D3 and autoimmune thyroid diseases (AITD).Methods Serum levels of 25-(OH) D3, thyroid antibodies (thyroid stimulating hormone receptor antibody (TRAb), TGAb (thyroid globulin antibody), thyroid peroxidase antibody (TPOAb) and thyroid function of 32 cases patients with Graves' diseases (GD), 17 cases patients without remission of GD,10 cases patients with remission of GD,35 cases patients with Hashimoto's thyroiditis (HT),and 58 cases healthy subjects were measured,and the relationships between serum 25-(OH) D3 and the above clinical index were analyzed.Results The serum level of 25-(OH) D3 in patients with GD or HT were obviously lower than that in healthy subjects((50.75±17.60) μg/L, (36.40±21.65) μg/L, (43.05±19.53) μg/L,P＜0.05).No significant difference of the serum level of 25-(OH) D3 was found between patients refractory of GD and those with GD in remission((32.43±17.50) μg/L, (31.88±14.48) μg/L,P=0.866).However,compared with the normal control group,both diseased groups showed significantly decrease (P＜0.05).No correlation was found between serum 25-(OH) D3 and TRAb, FT3, Fr4 as well as TSH in GD group.No correlation was found between serum 25-(OH) D3 and TGAb, TPOAb (P＞ 0.05).Conclusion Serum vitamin D levels are decreased in patients with AITD, which has been speculated as a potential therapeutic method for AITD, though further investigations are needed to establish the precise role of 25-(OH) D3 in AITD.

Objective To detect the effect of low-dose heparin on endothelial function by detecting the change of yon Willebrand factor (vWF) in blood plasma of patients with sepsis shock after treatment with low-dose heparin in order to observe organ function and prognosis of patients.Methods A total of 118 patients with sepsis shock were randomized into low-dose heparin group and control group.In addition to the routine treatment,the patients in low-dose heparin group were given low-dose heparin,while those in control group were not.The levels of APTT,PT,platelet (PLT) count,hepatic function and renal function were determined before and after treatment in two groups,and hemorrhagic events or other complications were recorded.The lengths of stay in ICU and in hospital,the days of mechanical ventilation and the rates of acute respiratory distress syndrome (ARDS),disseminated intravascular coagulation (DIC) and multiple organ dysfunction syndrome (MODS) and 28-day survival rate in the two groups were documented.The levels of vWF in patients of two groups were determined by using immunoturbidimetry before and after treatment.Results The rates of DIC and MODS in low-dose heparin group decreased significantly after therapy (rate of DIC,10.6％ vs.26.7％,P ＜ 0.05;rate of MODS,19.3％ vs.32.0％,P ＜ 0.05).Hepatic function and renal function in low-dose heparin group were significantly improved than that in the control group (P ＜ 0.05),28-day survival rate in the low-dose heparin group was higher than that in the control group (78.3％ vs.69.1％,P ＜0.05),the differences between low-dose heparin group and control group were not statistically significant in the lengths of stay in ICU and hospital,the days of mechanical ventilation and the rate of ARDS (P ＞ 0.05).The differences in APTT,PT and PLT were not significant from pre-treatment to after treatment and between the two groups (P ＞ 0.05).The levels of vWF in low-dose heparin group decreased significantly after therapy rather than those in control group (P ＜ 0.05).Conclusions The endothelial function is improved in patients with sepsis shock after employment of lowdose heparin.Low-dose heparin alleviates the interaction between coagulation and inflammation,improves hepatic,renal and other important organs function,decreases the rate of MODS and increases 28-day survival rate patients with sepsis.The low-dose heparin therapy is a safe and promising treatment in sepsis patients without severe side effects.
