Recently, compound Ejiao slurry (FFEJJ) had been applied to treat cancer patients in clinic, with obvious curative effect. In this study, data and literatures were collected from the TCM chemical component database to establish the chemical component database of FFEJJ. Afterwards, MetaDrug software was used to predict the targets of FFEJJ and obtain the compound-target network. Next, the compound-target network was compared and analyzed to obtain the "compound-target-tumor target" heterogeneous network. Besides, further analysis was made on gene functions and metabolic pathway. The results indicated that FFEJJ could directly resist tumors by regulating cancer cell differentiation, growth, proliferation and apoptosis, and show an adjuvant therapeutic effect by enriching the blood and increasing the immunity.

OBJECTIVETo observe the effects of signal factors of corticosterone (CS), cAMP, cGMP, Ca2+ andprotein kinase C (PKC) on lymphocyte apoptosis in mouse thymus induced by X-rays of 4 Gy in vitro.

METHODSThe DNA lytic rate for thymocytes was measured by fluorospectrophotometry.

RESULTSThe DNA lyric rate for thymocytes 4-8 hours after irradiation with 2-8 Gy was significantly higher than that in the control (P<0.01). As compared with the control, the DNA lytic rate for thymocytes treated with 0.01 micromol/L CS (P<0.01), 50 ng/mL cAMP (P<0.01), 0.05-0.4 microg/mL ionomycin (Iono, P<0.05 or P<0.01) or 0.05-0.4 ng/mL phorbol myristate acetate (PMA, P<0.05 or P<0.01), respectively, was significantly increased, while the rate for thymocytes treated with 50 ng/mL cGMP was not significantly increased. The DNA lytic rate for thymocytes treated with 0.01 micromol/L CS (P<0.01), 50 ng/mL cAMP (P<0.01), 0.2 and 0.4 microg/mL Iono (P<0.05), and 0.2 and 0.4 ng/mL PMA (P<0.05) plus 4-Gy irradiation, respectively, was significantly higher than that treated with single 4-Gy irradiation, while the rate for thymocytes treated with 50 ng/mL cGMP plus 4-Gy irradiation was not increased. When both 0.4 microg/mL Iono and 0.4 ng/mL PMA acted on the thymocytes, the DNA lytic rate for thymocytes was significantly higher than that in the control (P<0.01), the DNA lytic rate for thymocytes treated with both 0.4 microg/mL Iono and 0.4 ng/mL PMA plus 4-Gy irradiation was significantly higher than that treated with single 4-Gy irradiation (P<0.05), but was not significantly higher than that treated with 0.4 microg/mL Iono plus 4-Gy irradiation or 0.4 ng/mL PMA plus 4-Gy irradiation.

CONCLUSIONCS, cAMP, Ca2+, and PKC signal factors can promote thymocyte apoptosis induced by larger dose X-rays.

OBJECTIVETo evaluate the effectiveness of dynamic SPECT (99m)Tc-galactosyl human serum albumin (GSA) scintigraphy on the assessment of reserve function of cirrhosis liver.

METHODSFrom January 2010 to December 2011, 55 patients with cirrhosis liver were enrolled in this study. The case numbers of male and female were 43 and 12 respectively and the age was (51 ± 9) years (ranging from 35 to 69 years). After routine biochemistry test, CT scan and (99m)Tc-GSA dynamic SPECT scan were performed in turn using a juxtaposed SPECT/CT system. Then the morphologic volume of liver parenchyma (MLV), functional liver volume (FLV) and the hepatic cell absorption rate constant (GSA-K) were calculated. The correlations between GSA-K and routine biochemistry test, Child-Pugh score, indocyanine green clearance rate (ICG-K) were analyzed. The patients were further divided into 3 groups according to whether there was occlusion or stenosis in the main branch of left portal vein (group 1, n = 5), right portal vein (group 2, n = 13) or not (group 3, n = 37) and the regional hepatic functions index of the 3 groups were compared.

RESULTSThe value of FLV of the whole, left and right liver was (594 ± 152) ml, (244 ± 119) ml and (356 ± 171) ml, respectively. There were correlations between GSA-K and total bilirubin, prothrombintime, Child-Pugh score and ICG-K (r = -0.730--0.298, P < 0.05). The FLV and MLV ratios of involved hemiliver to uninvolved hemiliver were 0.09 ± 0.06 and 0.30 ± 0.14 in group 1, 0.57 ± 0.43 and 1.08 ± 0.63 in group 2, 0.71 ± 0.30 and 0.71 ± 0.48 in group 3. The difference in MLV-FLV ratio was signifcant between group 1 and group 3, between group 2 and group 3 (P = 0.000).

CONCLUSIONSThe dynamic SPCECT (99m)Tc-GSA scintigraphy can not only assess the whole liver function of cirrhosis liver effectively, but also evaluate the variation of regional liver function accurately.

OBJECTIVETo study the effect of Ar(+) laser on human vas deferens and to compare the effects of using different radiation levels with varying thickness of tissue and varying levels of injury.

METHODSAfter initial tests on animals, four human scrotums were opened and treated directly with Ar(+) laser radiation. Then 58 human individual scrotums were treated with radiation by the method of trans-skin puncture. The rate of sperm reduction and elimination was tested.

RESULTSIn 60 cases, the sperms were found to be eliminated completely after six months of radiation treatment. In 2 cases the sperms were found not to be eliminated completely due to the insufficient radiation.

CONCLUSIONAr(+) laser is one of the best forms of radiation for coagulation of vas deferens. It can be used to coagulate vas deferens without any complications or sequelae.

OBJECTIVETo evaluate the impact of viable myocardium assessed by (99)Tc()m-MIBI SPECT and (18)F-fluorodeoxyglucose (FDG) PET imaging in patients with left ventricular aneurysm (LVA) underwent revascularization (RVS).

METHODSForty-six consecutive patients with LVA (mean LVEF 36% +/- 7%), underwent (99)Tc(m)-sestamibi SPECT and (18)F-FDG PET examinations and received RVS therapy, were followed-up for a mean period of 80 +/- 27 months. Viable myocardium in aneurysm was defined as perfusion-metabolism mismatch score (MMS) >/= 2.0. Patients were divided into four groups by aneurysm viability and aneurysmectomy. Group A1 (n = 8): viability-; Group A2 (n = 15): viability-, aneurysmectomy; Group B1 (n = 10): viability +; and Group B2 (n = 13): viability +, aneurysmectomy.

RESULTSThe cardiac event rates during follow up were similar among groups [A1 (25%, 2/8), B1 (40%, 6/15), A2 (20%, 2/10) and B2 (31%, 4/13; P > 0.05)]. After revascularization, LVEF was improved (> 10%) in groups A2, B1 and B2 (P < 0.05). Multivariate logistic regression analysis showed that LV-MMS (OR = 2.34, 95% CI 1.08 - 5.06, P < 0.05), distal vessel disease (OR = 0.008, 95% CI 0.001 - 0.560, P < 0.05) and nonaneurysm perfusion score (OR = 0.24, 95% CI 0.07 - 0.85, P < 0.05) were significantly associated with the improvement of LVEF after revascularization.

CONCLUSIONSLong term cardiac events rate post revascularization was not affected by viable myocardium or aneurysmectomy in LVA patients. Viable myocardium in LVA patients was associated with better LVEF improvement after revascularization.

Objective: To investigate the current status of antithrombotic strategy for elderly patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) after stent implantation in Beijing area and to study the safety and efficacy of different therapeutic strategy. Methods: A total of 467 relevant patients were enrolled by re-travelling electronic medical records from 12 hospitals in Beijing area. The patients' mean age was (78.70±3.32) years and they were divided into 2 groups by antithrombotic therapy condition: Triple therapy group, n=17 (3.64％), Double therapy group, n=450 (96.36％). The incidence of major adverse cardiac and cerebral events (MACCE) including all-caused death, non-fatal myocardial infarction, stent thrombosis, target vessel revascularization (TVR), stoke and bleeding was compared between Triple therapy group and Double therapy group.Results: The medication in Double therapy group included aspirin+ticagrelor, aspirin+clopidogrel, clopidogrel+warfarin and cilostazol+clopidogrel; in Triple therapy group was aspirin+clopidogrel+warfarin. Patient with HAS-BLED score≥3 was defined as high risk of bleeding and they were all treated by double therapy; HAS-BLED<3 was defined as low risk of bleeding, only 5.03％ patients were treated by triple therapy. 3 patients in Triple therapy group and 33 in Double therapy group suffered from gastrointestinal bleeding, P=0.338; 6 patients in Triple therapy group and 128 in Double therapy group had MACCE, P=0.589; 3 and 80 patients died in Triple therapy group and Double therapy group, P=0.766. Conclusion: Triple therapy was rarely used in elderly AF and ACS patients after stent implantation, double therapy was the main strategy; the incidence of MACCE and mortality were similar between triple and double therapies; patients with triple therapy had the higher incidence of gastrointestinal bleeding.
