Objective To observe the effectivity and security of the therapy of patients with non ST segment elevation acute coronary syndromes (ACS) Methods In 165 patients suffering from ACS in recent 1 5 years, 89 patiens were treated with emergency interventional procedure meanwhile 76 patients were treated after medical therapy All “culprit" lesions were treated “non culprit" lesions of 41patients were treated at the same time Results 134 stents were implanted after PTCA and 48 stents were implanted directly in 165 “culprit" lesions Angina symptom of 136 patients disappeared, untypical chest pain of eleven patients disappeared after twenty four hours The uncomfortable symptom disappeared in fifteen patients, and alleviated in three patients There were no death cases and patients who needed emergency CABG During follow up from two to eighteen months, twenty patients suffered from angina again, and fourteen patients had restenosis confirmed by coronary angiography Eleven of them accepted PTCA again, one case accepted PTCA and stenting, and two of them accepted CABG No patients suffered AMI, sudden death and aggravation of heart function Conclusion The interventional treatment of non ST segment elevation ACS is positive and effective in a conditioned interventional center We have had satisfied clinical results

Aim To investigate the effect of selective cyclooxygenase-2 inhibitor, NS-398, on cell apoptosis in leukemia cell line K562 cells and its underlying mechanism. Methods Apoptotic cell percentage was examined by flow cytometry(FCM). The protein expression of Bcl-2 and Caspase-3 was detected by Western blot, and the activity of Caspase-3 was checked by FCM. Results NS-398 induced the cell apoptosis in K562 cells in a dose-dependent manner. After NS-398 treatment, the expression of Bcl-2 protein was downregulated, whereas the expression of Caspase-3 protein was upregulated. Moreover,the activity of Caspase-3 was increased in a dose-dependent way after NS-398 treatment. Conclusion Selective cyclooxygenase-2 inhibitor,NS-398,significantly induced apoptosis in K562 cells. The underlying mechanism might be related to the downregulation of Bcl-2 and the activation of Caspase-3.

Aim To observe the correlation between the TPL's suppression on myofibrolbasts(MFBs)activation and TGF-β1/ERK/Smad3 pathway by performing in vivo and in vitro experiments.Methods In vitro model of MFBs activation was set up by stimulating fibroblasts with TGF-β1,and in vivo model of MFBs activation in radiated lung tissue was built by thoracic radiation on C57BL/6 mice.MFBs activation was analyzed by detecting the expression of α-SMA(using RT-PCR and Western blot)and Col Ⅰ(using RT-PCR and ELISA methods).The levels of p-ERK,p-Smad3(Ser208)and p-Smad3(Ser423)were measured by Western blot.ERK siRNA and Smad3 siRNA were used to observe the status of ERK and Smad3 in MFBs activation.Results TGF-β1 activated p-ERK/p-Smad3(Ser208)and p-Smad3(Ser423),increased the expression of α-SMA and synthesis of Col Ⅰ,which indicated MFBs activation.siRNA knockdown assay showed that both ERK and Smad3 were involved in regulating the levels of α-SMA and Col Ⅰ,and ERK influenced MFBs transformation possibly through its phosphorylation of Smad3(Ser208).TPL treatment inhibited the phosphorylation activation of ERK,Smad3(Ser208),Smad3(Ser423)in vitro and in vivo,therefore significantly reduced the level of α-SMA and Col Ⅰ,and the number of activated MFBs was decreased.Conclusion TPL mitigates radiation-induced pulmonary fibrosis by inhibiting the activation of MFBs,which is partly through suppressing TGF-β1/ERK/Smad3 pathway.

An actinomycete B37 was isolated from an intertidal marine sponge Hymeniacidon perleve, which has strong activity against Gram positive bacteria and moderate activity against tumor cells. The mycelium and spore morphology, physiological properties and 16SrDNA sequence suggested that B37 is Streptomyces pseudogriseolus. The fermentation conditions of this strain were investigated for the biosynthesis of bioactive metabolites.

OBJECTIVETo explore the effects of warm needling combined with Zhangmo decoction (see text) on endometrial receptivity in patients with clomiphene (CC)-induced ovulation.

METHODSOne hundred and sixty cases were randomly divided into a CC group (group A), a CC+ progynova group (group B), a CC+ Zhangmo decoction group (group C) and a CC+ Zhangmo decoction + warm needling group (group D), 40 cases in each one. In the Group A, CC alone was applied. In the group B, progynova was jointly used on the 8th day of menstrual cycle. In the Group C, Zhangmo decoction was jointly used on the 5th day of menstrual cycle. In the group D, based on treatment of the Zhangmo decoction, warm needling was applied at Guanyuan (CV 4), Zhongji (CV 3) and Zigong (EX-CA 1) etc. The endometrial thickness and type, pulsatility index (PI), resistance index (RI), ratio of S/D on day of human chorionic gonadotropin (HCG) and pregnancy rate were observed in fou groups.

RESULTSThe PI, RI and S/D in the group C and D were obviously lower than those in group A and B (all P < 0.01). The endometrial thickness was (7.7 +/- 1.49) mm in group B, (8.2 +/- 1.54) mm in group C and (8.9 +/- 1.51) mm in group D, which were significantly different from (6.4 5 +/- 1.26) mm in the group A (all P < 0.01) also there was a significant difference between group C and D (P < 0.05). The rate of endometrial type A was 65.0% in the group D, which was significantly higer than 27.5% in the group A, 32.5% in the group B and 35.0% in the group C (all P < 0.01). The pregnancy rate was 30.0% in the group D, which was obviously higher than 12.5% in the group A, 15.0% in the group B and 17.5% in the group C (P < 0.05). The endometrial thickness and rate of endometrial type A in the pregnant were obviously higher than those in the non-pregnant (both P < 0.01) while PI, RI and S/D was lower than those in the non-pregnant (P < 0.01, P < 0.05).

CONCLUSIONWarm needing combined with Zhangmo decoction could improve endometrial thickness, morphology and uterine spiral artery to improve pregnancy rate, which has superior effect to clomiphene, clomiphene combined with progynova and clomiphene combined with Zhangmo decoction.
