Objective To observe the influences of Yangxinshi pill on ET, NO, CRP in patients with angina pectoris belonging to manifestation of Qi-deficiency and blood stagnation. Methods 78 patients with angina pectoris were randomly divided into two groups. 40 patients in treatment group were treated with Yangxinshi pill, 4 pills once, three times a day 8 weeks. 38 patients in control group were treated with isosorbide mononitrate 8 weeks. The symptoms and the ET, NO, CRP level before and after treatment were recorded. Results Obvious drop of ET, NO, CRP were observed after treatment in the treatment group. The level of ET was reduced from (67.47?15.72)pg/mL to (37.97?7.82) pg/mL. The level of NO was increased from (78.24?13.81)?mol/mL to (96.25?12.72)?mol/mL. The level of CRP was reduced from (5.31? 2.02)mg/L to (3.42?2.17) mg/L. There was a significant difference between the two drugs (P 0.05). The total efficacy rate in improving symptom was 95%. There was a significant difference between the two drugs (P

Methods Based on the optimum parameter of ultrasound wave irradiation (0.5 W/cm2 ,30 s) selected in pre-experiment,HeLa cells were divided into 5 groups:(A)simple plasmid group,(B)plasmid-ultrasound group,(C)plasmid-ultrasound-microbubble group,(D)plasmid-liposome group,(E)blank control group. At 24-48h after transfection,the transfection efficiency was detected by fluorescence microscope,the mRNA expression of p53 was detected by RT-PCR,the cell cycle was detected by flow cytometry,and the inhibition rate of cells growth was detected by MTT assay. Results Fluorescence microscopy showed that the expression of green fluorescent protein in group C was higher than that in group Band group D (P

Objective To explore the value of human epididymis protein 4(HE4),cancer antigen 125(CA125) and the risk of ovarian malignancy algorithm(ROMA) in the diagnosis of ovarian cancer.Methods Electrochemical luminescence and Enzymelinked immunosorbent assay (ELISA) were used to determine the levels of serum HE4,CA125 in 56 patients with ovarian carcinoma,73 cases of ovarian benign tumor and 50 health women,and the ROMA was calculated by HE4 and CA125 levels depending on the menopause state,drawing the receiver operating characteristics(ROC) curve and calculating the area under the curve(AUC).Results The average levels of the HE4,CA125 and the value of the ROMA were (345.33±605.03)pmol/L,(701.46±1 500.30) U/mL,(58.72±31.00) ％ in the ovarian carcinoma group,(53.84± 14.68)pmol/L,(44.25±45.81)U/mL,(10.80± 6.75) ％ in the ovarian benign tumor group,and (46.03±10.26)pmol/L,(17.39±10.64)U/mL,(6.92±3.85)％ in the health control group respectively,compared with the benign tumor group and the health control group,the ovarian carcinoma group were higher in HE4,CA125 and the ROMA value,and the difference were significantly (P＜0.05),whereas compared in the ovarian benign group and the health group,except the CA125 was higher in the benign group and the difference had statistical significance(P＜0.05),the HE4 level and the value of the ROMA had no statistical significance(P＞0.05).The sensitivities of the HE4,CA125 and ROMA were 71.43％,76.79 ％,89.28％,the specificities were 93.15 ％,53.42％,94.52 ％ and the ROC-AUCs were 0.930,0.809,0.937 respectively.When the specificity for the diagnosis of the ovarian carcinoma was 95.00％,the sensitivities of the HE4,CA125 and ROMA were 80.40％,53.60％,83.90％ respectively.Conclusion HE4 and CA125 combined detection to calculate the ROMA can elevate the sensitivity and specificity for the ovarian carcinoma diagnosis.

Objective To observe the distribution and the effect of the quantum dots(QDs) on mouse abdominal cavity macrophages.Methods The QDs were co-cultured with mouse abdominal cavity macrophages in vitro.The differentiation and effect of the QDs on macrophage ultrastructures were observed under electronic microscope. Results The QDs were enveloped with unit membrane and internalized in the cytoplasm of the macrophage under transmission electron microscope.And it formed vacuolelike structures in the macrophage.There were many lamellar processes on the surface of the macrophage under scanning electron microscope.Conclusion The QDs can promote macrophage activation,and make its surface projection increased.The QDs were internalized by the macrophage,distributed in the cytoplasm,and formed vacuolelike structures enveloped with unit membrane.

BACKGROUND:The research at home and abroad for appropriate immature myocardial cardioplegia has no breakthrough, and it may be a better mean to improve the protection effect of existing cardioplegia on immature myocardial by adding ingredients. Adenosine can reduce ischemia and neutrophil-mediated reperfusion injury, and salvia miltiorrhiza can reduce the content of ischemic myocardial lipid peroxide and increase the scavenging of myocardial cells to oxygen radical. OBJECTIVE:To investigate the protection effect of improved myocardial protection fluid containing adenosine and salvia miltiorrhiza on the heart, liver and kidney. METHODS:Sixty cases of infant open heart operation of the first time were randomly divided into three groups, 20 cases in each group. The adenosine group received the improved myocardial protection fluid added with adenosine, the combination group received the improved myocardial protection fluid added with adenosine and miltiorrhiza salvia, and the control group received the improved myocardial protection fluid in the same volume. The blood samples were taken at the time before anesthesia induction, 30 minutes after cardio pulmonary bypass beginning, 1 hour after cardio pulmonary bypass end and 24 hours after cardio pulmonary bypass end. The serum levels of the creatine kinase, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine, tumor necrosis factor-α, interleukin-6, interleukin-8 and interleukin 10 were detected. RESULTS AND CONCLUSION:The serum levels of the alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine and creatine kinase in three groups were increased, but the control group was increased significantly (P<0.01), and there were significant differences between adenosine group and combination group (P<0.05);the levels of tumor necrosis factor-α, interleukin-6 and interleukin-8 were significantly increased after operation (P<0.05). The levels of tumor necrosis factor-α, interleukin-6 and interleukin-8 in the control group were significantly higher than those in the adenosine group and combination group before induction and at the same time point (P<0.01);at 3 minutes and 24 hours after cardio pulmonary bypass, the level of interleukin-10 was increased in three groups, but the level of interleukin-10 in the adenosine group was significantly higher than that in the control group (P<0.01). The results indicate that improved myocardial protection fluid has great protection effect on immature myocardial, and can significantly reduce the serum levels of tumor necrosis factor-α, interleukin-6 and interleukin-8, promote the secretion of interleukin-10 that can inhibit inflammatory cytokine and can significantly reduce the inflammatory response caused by cardiopulmonary bypass. So the improved myocardial protection fluid has protection effect on important organs, such as heart, lung, liver and kidney.

Objective Irregular antibody screening and identification are very important to reduce hemolytic reaction.The dis-tribution of irregular antibodies of blood group was analyzed in patients, to provide evidence for using Micro column gel test to detect and identify irregular antibodies transfusion safety. Methods Micro column gel anti-globulin technique was used to screen the irregular an-tibodies and cross-matching in 29770 patients.If the serum had irregular antibodies, the spectrum cells were used to identify the specific-ity of irregular antibodies. Results Among 29 770 patients, 120 cases had irregular antibodies of blood group.The positive rate was 0.4%.The irregular antibodies include Rh system(n=67),MNS system (n=7), Lewis system(n=5),cases of Kidd system(n=3) and undefined specified antibodies(n=38).Among the 120 antibody-positive patients, 70 were female patients and 50 were male patients. Further study showed that the pregnancy history was to the main factor causing irregular antibodies in women (46 positive cases among 70 female patients) . Conclusion The study showed that some patients had irregular antibodies of blood group, especially female patients with pregnancy history.These results suggested that irregular antibody screening and cross-matching by micro column gel method in pa-tients before transfusion had great significance for ensuring the blood transfusion safety.
