The compound that distributes in the herbs with one common effect was named as "co-effect compound" (CEC). The CECs of three traditional Chinese medicine(TCM) effects, purgative, relieving pain and clearing heat, had been found and studied. A strong corresponding relationship was found between the pharmacological activities of CECs and the TCM effect they belong to. The study shows that it may be a feasible method to connect traditional effect of TCM with modem pharmacological activity.

The Monascus mutant with high yield of yellow pigment was obtained by using conventional relevant mutation techniques, e.g., treating with physical mutagens(such as UV light) and chemical sub- stances (such as N-methyl-N'-nitro-N-nitrosoguanidine). The yellow pigment was scanned from 300 nm to 600 nm with UV spectrometer, the maximal absorption was determined at 410 nm. The growth characteristic of Monascus mutant is stable, the yellow pigment value and colour hue in liquid fermentation can reach 100 U/mL and 3.5 respectively. The yellow pigment is stable from pH 3 to pH 8, but the precipitation appeared as the pH of the pigment solution lower than 3.

OBJECTIVETo investigate the diagnosis, surgical procedure and clinical outcome of cervical intraspinal benign neoplasm.

METHODSTwenty-two cases confirmed pathologically were reviewed included 16 males and 6 females with an average age of 43.8 years old ranging from 18 to 56 years. Symptoms mainly included neck pain, numbness and weakness of the extremities, urinary and fecal incontinence, pyramid signs, etc. All underwent X-ray, CT and MRI, 11 cases were diagnosed as neurilemomas, 4 neurofibromas, 3 spinal meningiomas, 2 intraspinal cysts and 2 lipomas. The tumors were removed completely in 18 cases, above 60% in 3 cases and 25% with biopsy in 1 case. Cervical stability in 11 cases was restored after removal of tumors.

RESULTSAll were followed-up for from 6 to 84 months(means 12.5 months). Symptoms improved in 20 cases and stable in 1 case and worsened in 1 case postoperatively according to JOA scoring system. Two patients recurred and were treated with second surgery. JOA scoring was (6.52 +/- 1.10) before operation, (11.42 +/- 0.79) after operation, there was statically significance (t = 21.38, P < 0.001). The average recover ratio of total was (46.7 +/- 2.46)%, cervical stability was (62.37 +/- 3.58)%, the other methods was (41.21 +/- 4.63)%. The results of JOA were excellent in 18 cases, good in 2, fair in 1 and poor in 1.

CONCLUSIONThe surgical exairesis for cervical intraspinal benign neoplasm has low post-operative recurrence. The main reason of recurrence is not removed the tumor completely. MRI is regarded the effective method which is helpful in differential diagnosis and surgery guidance.

Objective To analyze the viral genetic characteristics of hantaviruses carried by Microtus maximowixzii in Yakeshi of Inner Mongolia Autonomous Region and its relationship with Hantaan virus (HTNV) and Seoul virus (SEOV) viruses as well as to identify the natural host of Khabarovsk virus (KHAV).Methods HV specific RNAs were detected by RT-PCR.Complete S and M segment were amplified from the RNA-positive samples.Phylogenetic analysis were performed to estimate the genetic characterization and the relationship with other hantaviruses.Results Fifty two Microtus maximowixzii voles were captured in Yakeshi areas.Of those voles,hanta-viral RNA was tested positive in 5 samples (9.62％).Complete S and M segments sequences were obtained from 5 and 2 lung samples,respectively.The complete S segment was consisted of 1848 to 1861 bp,and the M segment consisted of 3662 bp.These viruses were closely related to each other with 92.5％-96.4％ for the S segment sequences and 88.9％-95.4％ for the M segment sequences.They shared a higher identity with KHAV found previously in Yakeshi and KHAV of Russia.However,they were obviously different from the other hantavirus species.The 5 strains had the consistent secondary structure of nucleocapsid protein (NP) and glycoprotein (GP).When further comparing their secondary structures with those of HTNV and SEOV,our results indicated that there were no obvious differences in NP between KHAV and both HNTV,SEOV but with obvious difference in GP.Based on the S and M segment sequences,phylogenetic analyses revealed that these 5 strains clustered together with KHAV and formed a distinct lineage.Furthermore,all known KHAV strains could be divided into two small branches with a nucleotide divergence more than 5.3％.Conclusion Our research data revealed that KHAV was highly endemic among Microtus maximowixzii in Yakeshi area which supported the notion that Microtus maximowixzii had been the natural host of KHAV in the area.

The purpose of this study was to determine the combined effect of transmyocardial laser revascularization (TMLR) and the implantation of endothelial progenitor cells (EPCs) on cardiac function of ischemic hearts in canines. The left anterior descending artery (LAD) was occluded to establish the canine model of acute myocardial infarct (AMI). Four weeks later, the animals were randomly divided into four groups: TMLR group, in which transmyocardial laser-induced channels were established at the ischemic region; EPCs+TMLR group, in which EPCs were locally transplanted into laser-induced channels at the ischemic region; EPCs group, in which the EPCs were injected into the ischemic region; control group, in which the AMI animals received neither TMLR nor EPCs. The peripheral blood (50 mL) was sampled in all groups. Mononuclear cells from the peripheral blood were separated and cultured to obtain spindle-shaped attaching (AT) cells in vitro. AT cells were labeled with 1, 1'-dioctadecyl-1 to 3,3, 3',3'-tetramethyl-indocarbocyanine perchlorate (DiI) before injecting into the laser-induced channels or ischemic region. Four weeks after the first operation, TMLR was performed in the TMLR group and EPCs+TMLR group, and at the same time, the EPCs originating from the AT cells were mixed with calcium alginate (CA). Then the EPCs-CA composites were implanted into myocardial channels induced by laser in the EPCs+TMLR group, and into the myocardial infarct area in the EPCs group. All dogs underwent echocardiography at second month after LAD occlusion. Finally the samples of myocardium around the LAD were subjected to histochemical and immunohistologic examinations. The results showed there was no significant difference in the diameter of left atrium and ventricle before treatment among all groups (P>0.05). Eight weeks after modeling, the regional contractility in the LAD territory in the EPCs+TMLR group was increased as compared with control group and TMLR group, but there was no significant difference between control group and TMLR group. Neoangiogenesis was observed in the EPCs+TMLR group, and the fibrosis was seen in the TMLR group. There was no significant difference in neoangiogenesis around the channels induced by laser among EPCs+TMLR, EPCs and TMLR groups. It was concluded that TMLR combined with EPCs could improve the regional and global cardiac function in AMI, and augment neovascularizaiton in channels of ischemic myocardium induced by laser.

BACKGROUNDThe Firebird 2(TM) sirolimus-eluting stent (Firebird 2 stent) is a second-generation sirolimus-eluting stent which has a cobalt-chromium alloy stent platform, a brand new bracket structure, and two layers of styrene-butylenes-styrene polymer coatings with better biocompatibility. The Firebird 2(TM) cObalt-Chromium alloy sirolimus-elUting Stent registry (FOCUS registry) aimed to evaluate the safety and efficacy of the Firebird 2 stent in patients with coronary artery disease in daily practice.

METHODSThe FOCUS registry is a prospective, non-randomized, international multi-center, single-arm clinical registry. Between March 2009 and February 2010, 5084 patients receiving at least 1 Firebird 2 stent during daily clinical practice at 83 medical centers were enrolled.

RESULTSOf the 5084 patients enrolled in the registry, 5077 and 5058 were respectively available for 30 days and 6 months follow-up. The 30-day rate of major adverse cardiac events (MACE) was 1.20%, including 13 cardiac deaths, 46 non-fatal myocardial infarction (MI), and 6 target vessel revascularization (TVR). At 6 months follow-up, the rate of MACE was 1.80%. There were 32 cardiac deaths, 48 non-fatal MI, and 15 TVR. According to the Academic Research Consortium definition, definite/probable stent thrombosis (ST) occurred in 0.43% (22/5058) of patients, including 8 cases of acute ST, 11 subacute ST, and 3 late ST.

CONCLUSIONThe Firebird 2 stent showed the promising efficacy and safety at 30 days and 6 months in a real-world population of patients with coronary artery diseases.
