Objective To explore the difference of plasma pentraxin 3 (PTX3) levels in acute coronary syndrome (ACS) patients,and to evaluate the correlation between plasma PTX3 levels and ACS as well as hypersensitive C-reaction protein (hs-CRP), through detecting the plasma levels of PTX3 and serum levels of hs-CRP in ACS patients, stable angina pectoris (SAP) patients and normal controls. Methods According to coronary angiography results,78 subjects were divided into control group (n = 20), stable angina pectoris (SAP) group (n = 22), and acute coronary syndrome (ACS) group (n = 36). The plasma levels of PTX3 and serum hs-CRP as well as routine blood biochemical markers were detected on the second day after admission. SPSS10.0 was used for one-factor analysis of variance and Logistic regression analysis. Results The logarithm level of plasma PTX3 in ACS group was significantly higher than that of the other two groups (P <0.05). The difference between the SAP group and the control group was not statistically significant (P > 0.05). Logistic regression analysis revealed that the estimated value of the plasma PTX3 logarithm level was 2.32 (P < 0.05), that of the serum hs-CRP was 0.447 (P > 0.05). Conclusion The plasma PTX3 level in ACS group is significantly higher than that of the SAP group and the control group. The correlation between plasma FTX3 levels and the ACS is stronger than that of the serum hs-CRP levels.

Objective To investigate the infection rates of mycoplasma penetrans (Mpe),mycoplasma pneumoniae (Mp) and mycoplasma ferments (Mf) in patients with IgA nephropathy (IgAN),chronic kideny disease (CKD),and heathy people,to compare the difference of infection rate,and to analyze the association of mycoplasma infection and clinicopathological features in IgAN.Methods Blood samples were collected from 118 patients in IgAN group,90 patients in CKD group,and 89 cases in health control group.DNA of Mpe,Mp and Mf was detected in plasma by PCR.Positive cases were confirmed by Southern blot.According to mycoplasma infection,IgAN patients were divided into two groups,then analyzed the clinicopatholgical features.Results (1)Genus,Mpe,Mp,and Mf positive rates were 33.05％,16.1％,25.45 ％,and 8.47％ in IgAN group,respectively; 5.56％,2.22％,5.56％,and 2.22％ in CKD group,respectively; and 3.33 ％,1.11％,2.22％,and 0 in health group,respectively.Compared with CKD and health group,patients in IgAN group had a higher infection rate in Genus,Mpe,and Mp (P ＜ 0.05).In IgAN group,10 patients had three kinds of mycoplasmas infection at the same time,and positive rate was 8.47％ much higher than CKD group (positive rate was 2.22％) (P ＜ 0.05).(2) Based on mycoplasm detection results,IgAN patients were divided into two groups,overlapping infection group and mycoplasma negative group.In overlapping infection group,the mean age of onset was much younger than negative group.Compared with negative group,overlapping infection group had higher tonsillitis and urinary tract infection rate,more severe microscopic hematuria and tubulointerstitium lesion (P ＜ 0.05).Conclusions Patients with IgAN had higher infection rate of Genus,Mpe and Mp,compared with CKD patients and health people.Compared with mycoplasma negative group in IgAN patients,more severe microscopic hematuria and tubulointerstitium lesion in overlapping infection group,which suggested that infection of Mpe might have some possible connection with IgAN.

ObjectiveTo investigate the protective effect of tanshinoneⅡA on the expression of S100A1 protein after acute myocardial ischemia injury in rats.Methods Sixty Wistar rats were randomly divided into sham operation group, acute myocardial ischemia model group and tanshinoneⅡA pretreatment group by random number table. The acute myocardial ischemia model was established by thoracotomy and penetration of a thread and occlusion around the root part of the left anterior descending coronary artery, while the sham operation group was established only by thoracotomy and penetration of a thread around the root part of that artery but without occlusion; 3 days before the operation, in the tanshinoneⅡA pretreatment group, intraperitoneal injection of tanshinoneⅡA solution(at a dose of 1.5 mg/kg) was applied, while in the sham and acute myocardial ischemia groups, intraperitoneal injection of an equal volume of saline was given. Myocardial cell apoptosis was detected by the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL), the levels of serum superoxide dismutase (SOD), malondialdehyde(MDA), creatine kinase(CK), lactate dehydrogenase(LDH) and S100A1 protein were examined and the level of expression of S100A1 protein in myocardial tissue was assayed by immunohistochemical staining and Western Blot.Results Compared with the sham operation group, the myocardial cell apoptosis rate, the contents of MDA, CK, LDH, S100A1 and the level of S100A1 expression in myocardial ischemia group and tanshinoneⅡA pretreated group were significantly increased, while SOD activity was decreased obviously; compared with the myocardial ischemia model group, the myocardial cell apoptosis rate, the contents of MDA, CK, LDH, S100A1 and the level of S100A1 protein expression were significantly reduced〔apoptosis rate:(32.1±4.2)% vs.(72.4±5.4)%, MDA(μmol/L): 9.1±2.2 vs. 17.3±5.2, CK(U/L): 83.3±12.2 vs. 107.5±12.4, LDH (μmol·s-1·L-1): 84.0±16.4 vs. 114.4±16.0, S100A1(μg/L): 37.6±6.0 vs. 78.4±8.6,P<0.05 orP<0.01〕, while the activity of SOD was increased markedly in tanshinoneⅡA pretreated group(kU/L:72.8±10.2 vs. 49.6±8.8,P<0.01). TUNEL staining showed that in the myocardial ischemia model group and tanshinoneⅡA pretreated group, the myocardial cells represented positive staining(brown-yellow in color), irregular in shape with nuclear pyknosis, cell detachment from the surrounding tissue and other characteristics. And in sham operation group,the staining of majority of cells was negative. The results of immunohistochemistry showed that S100A1 protein staining was relatively deep in the myocardial ischemia model group and tanshinoneⅡA pretreated group, and in the latter group, the color of S100A1 protein positive staining was not as deep as that in the former group. Western Blot showed that the S100A1 protein expression in myocardial ischemia model group was 2.8 folds of that of the sham operation group, while the S100A1 protein expression in tanshinoneⅡA pretreated group was significantly decreased compared with that of myocardial ischemia model group(bothP<0.05),which was 1.5 folds of that of the sham operation group.ConclusionTanshinoneⅡA may play a role in inhibiting the expression of S100A1 protein to protect against acute myocardial ischemia injury, suggesting that this agent have a potential effect for treatment of myocardial ischemia.

Objective To explore the effects of cyclophosphamide administered by different routes or in different doses on the embryo-fetal development in pregnant rabbits, and to determine the optimal mode of cyclophosphamide administration to induce fetal malformation.Methods Pregnant rabbits were divided into control group C (saline), group Y1 (intravenous injection of 15 mg/kg cyclophosphamide,), group Y2 (subcutaneous injection of low dose cyclophosphamide, 20 mg/kg), and group Y3 (subcutaneous injection of high dose cyclophosphamide, 30 mg/kg).Each rat was administrated according to the corresponding mode once daily on GD10~13.The day of conception was designated as GD0.The pregnant rabbits were sacrificed and dissected on GD28.Then, the number of corpora lutea and implantation, the weight of uterus with contained fetus, and fetal resorption rate were detected, the fetuses were removed and the fetal sex, body length, tail length, the number of live births and stillbirths were recorded, and the appearance of deformities, visceral deformities and skeletal malformations were detected.Results Pregnant rabbit fetuses in the cyclophosphamide intravenous injection group and subcutaneous injection of low dose cyclophosphamide group showed deformities.The appearance malformation rates in the two groups were 30.77% and 95.65%, the skeletal deformity rates were 7.69% and 73.91%, and the visceral abnormality rates were 20.51% and 47.83%, respectively.The fetal resorption rate in the high dose cyclophosphamide subcutaneous injection group was 100%.Conclusions Subcutaneous injection of 20 mg/kg cyclophosphamide to pregnant rabbits at GD10~13 can be used as a positive administrationmethod for rabbit embryo-fetal developmental toxicity test.Thismethod has the advantages of short administration period, easy operation, few fetus resorption, and high rate of fetal malformation, thus, providing the evidence for selection of appropriate model of rabbit embryo-fetal developmental toxicity.
