Objective To observe the function of recombinant human tissue factor pathway inhibitor1(rTFPI-1)in acute myocardial infarction in rabbit. Method Forty New Zealand White rabbits were subjected to coronary artery occlusion for 120 min and followed by reperfusion for 60 min,then they were ranlow dose rTFPI-1 group(n=10/group).The extent of ischemic area and the extent of myocardial infarction area were measured by Evan's blue stain and TTC stain,respectively.The degrees of infarction severity and ischemic severity were expressed as the ratios of the total left ventrieular wall area.The degrees of infarction severity and ischemic severity in different groups were compared by using one-way ANOVA and then followed by LSD procedure.Results The degree of infarction severity in the larger dose rTFPI-1 group was significantly lessened than that in low dose RTFPI-1 group and control group(P<0.001),and than that in modcrate dose rTFPI-1 group as well(P<0.05).The degree of infarction severity in the moderate dose rTFPI1 group was significantly lessened than that in low dose rTFPI-1 group and control group(P<0.001).There was no significant difference in degree of infarction severity between low dose rTFPI-1 group and control group(P>0.05).Conclusions Human rTFPI-1 might decrease myocardial infarction severity and save the survival myocardial tissue.

Objective To investigate the efficacy of gelatin sponge particles(GSP)or polyvinyl alcohol particles (PVA) for hemoptysis secondary to bronchiectasis or pulmonary tuberculosis. Methods The clinical data on 271 patients with bronchiectasis- or tuberculosis-induced hemoptysis were retrospectively analyzed. The efficacy and rates of recurrence and complications were analyzed. Results A total 271 patients were included in this study, 176 of whom suffered from bronchiectasis and the rest 95 had tuberculosis. One-week cure rate was signifi-cantly higher in bronchiectasis group than in tuberculosis group(73.3%vs. 46.3%,P<0.05),and one-year recur-rence rate was significantly lower in bronchiectasis group(17.6%vs. 26.3%,P<0.05). One-year recurrence rate was slightly higher in patients receiving GSP than in those undergoing PVA(bronchiectasis group:22.2%vs. 10.3%, P<0.05;tuberculosis group:28.8%vs. 22.2%,P>0.05). No severe complications occurred. Conclusions In-terventional artery embolization therapy for hemoptysis secondary to bronchiectasis is better than tuberculosis-induced hemoptysis,and PVA is more effective than GSP. Recurrence of massive hemoptysis mostly occurrs within one month ,and most of the patients are complicated with blood supply and have a history of hemoptysis.

Objective To evaluate the acute and long-term results of stenting for left main coronary artery (LMCA) bifurcation lesions. Methods Forty consecutive patients with LMCA bifurcation lesion and normal left ventricular function were included. Sirolimus-eluting stents were performed in all patients. Results (1)The average diameter of LMCA was (0.81?0.48)mm before stenting and increased to (3.53?0.22)mm after stenting.(2)The procedural success rate was 100.0%. In-hospital events including stent thrombosis,Q-wave myocardial infarction,and emergency bypass surgery did not occur in any patients,and non-Q-wave MI in one patient (2.5%).(3)Clinical follow-up was obtained in all patients at (8.43?3.24) months. There were no death and no myocardial infarction during follow-up. The major adverse cardis events rate was 20.0%.(4)The angiographic follow-up rate was 67.5% (27 of the 40 eligible patients),and the restenosis rate was 18.5% (parent vessel only 11.1%,side branch only 3.7%,and both 3.7%).(5)Different type of operation had no influence on restenosis rate during angiographic follow-up. Conclusion Sirolimus-eluting stent implantation for LMCA bifurcation stenosis appears safe and effective with regard to acute and midterm complications.

BACKGROUND: The strength and elasticity of general starch can be enhanced dramatically after plastic blends. The major characters of this material are magnitude molecular weight, many enwinded points, extreme containment of small molecules,and great gelation ability. It can be used as a biodegradable replacement of alginate. Furthermore, by adding osteoinductive factors, thermoplastics starch (TP) can be used as an organic engineering material, which can provide dual functions:anti-bleeding and bone formation. TP can also be used as intraoral tissue formation membrane and burn dressings.OBJECTIVE: To evaluate the bio-safety of TP through a cytotoxicity test.DESIGN: A controlled observation.SETTING: Beijing Research Institute of Traumatology and Orthopaedics; Beijing Jishuitan Hospital; Beijing University of Chemical Technology; Peking Univesity School of Stomatology.MATERIALS: The experiment was conducted at the laboratory of Beijing Research Institute of Traumatology and Orthopaedics from April to October in 2006. TP sample was obtained by plasticization of corn starch (12 wt % water content) with glycerol in a Haake Rhenmix at 110℃ and with 80 rounds per minute for 25 minutes, elongation at break from 115.3% to 245.3%. It was prepared by Beijing Key Laboratory for Preparation and Processing of Novel Polymeric Materials, Beijing University of Chemical Technology. Mouse fibroblast L-929 cell strain was provided by the cell bank of Peking University Health Science Center.METHODS: 1 × 107 L-1 cell aqueous suspension was cultured into leaching liquor ( 50% ), serving for TP group, and routine culture medium served for negative control group. Effect of TP on relative growth rate of L-929 cell strain was quantitatively measured by MTI" assay. The cytotoxicity of TP was evaluated according to GB/T16175-1996. Morphological changes and proliferation of cells were observed after2, 4, and 7 days of culture in the medium through an inverted phase contrast microscope.MAIN OUTCOME MEASURES: Cytotoxicity, morphological changes and proliferation of cells, and cell relative growth rate.RESULTS: Cytotoxicity: After 2 and 4 days of incubation, the absorbance (A) value was lower in the TP group than in the negative control group. After 7 days of incubation, the A value was significantly higher compared to negative control group (P＜0.01). It indicated that after 2 and 4 days of incubation, the cytotoxicity in the TP group was larger than in the negative control group, while after 7 days of incubation, it was on the opposite. All the test time, TP's cytotoxicity grade ranged from 0 to 1. Morphological change and proliferation of cells: After 2 days of incubation, both groups of cells were not extended to the outside of the scope, with a majority shape of being round, triangle, and quadrangle in the TP group or fusiform cells in the negative control respectively. Four days later, there were gaps among cells in the TP group, while in the negative control group, there were hardly any distance between cells and some cells piled up. Seven days later, cells in starch medium suddenly grew up to such a degree that all the cells lapped over and presented with more bloom than the negative control. Cell relative growth rate: After 2, 4, and 7 days of incubation, relative growth rate increased with time, being 85.63%,82.22%, and 113.05%, respectively.CONCLUSION: TP has no evidence of cytotoxicity and has good bio-safety.

Twelve populations of Inula lineariifolia were used as materials to measure morphological characteristics, photosynthetic parameters and chemical constituents. It aims to provide a theoretical basis for germplasm resources evaluation. The results showed that I. lineariifolia had relatively rich morphological diversity, there were significant differences of morphological characteristics, photosynthetic parameters and chemical constituents among populations. There was positive correlation on morphological characteristics and P(n). Twelve populations were divided into three-type. The three populations of Xuyi, Mingguang and Fengyang were of narrower-longer leaf, bigger biomass,better photosynthetic and higher chemical constituents. Then they were classified for a similar group. It proved that the three populations were more suitable for cultivation and promotion.

Abstract: Objective 　To investigate the population densities composition and seasonal change of mosquitoes, and resistance of Culex pipiens quinquefasciatus and Aedes albopictus several commonly used insecticides in Zigong, so as to provide a theoretical basis for guiding the scientific rational selection and use of chemical insecticides, as well as the prevention and control of mosquito-borne diseases. Methods　The surveillance data on mosquitoes by traps were collected from 2018 to 2020 in Zigong. The wild Culex pipiens quinquefasciatus and Aedes albopictus were collected throughout the city and reared to F1 generation in lab. The resistance of adult Culex pipiens quinquefasciatus and Aedes albopictus to these commonly insecticides was detected by contact tube method recommended. The statistical analysis on the monitoring results was used by Excel 2010. Results　The annual average mosquito densities of monitoring sites were 1.11, 10.71, and 4.81 mosquitoes/(lamp·h), respectively from 2018 to 2020. The seasonal density of mosquitoes showed a single peak curve distribution throughout the year from 2018 to 2020 in Zigong, with the highest in July. There were obvious differences in mosquito density between different habitats, with the highest density of mosquitoes in barn. The 24 h mortality of Aedes albopictus and Culex pipiens quinquefasciatus to beta-cypermethrin, lambda-cyhalothrin, deltamethrin, permethrin, malathion, fenitrothion, chlorpyrifos, propoxur, and bendiocarb were 70.71% and 3.85%, 26.53% and 1.68%, 19.79% and 1.94%, 40.80% and 0.81%, 97.98% and 3.85%, 100.00% and 7.52%, 100.00% and 66.34%, 96.15% and 33.60%, 100.00% and 71.43%, respectively. The adult Aedes albopictus larvae in Zigong was sensitive to fenitrothion, chlorpyrifos, bendiocarb, showed resistance to beta-cypermethrin, lambda-cyhalothrin, deltamethrin, permethrin, and showed resistance dubiously to malathion and propoxur. The adult Culex pipiens quinquefasciatus larvae in Zigong have developed certain resistance to these commonly insecticides. Conclusion　Both Culex pipiens quinquefasciatus and Aedes albopictus had high resistance to pyrethroid insecticides, which suggested that we should strengthen the patriotic hygiene campaigns, reduce pyrethroid insecticides, use alternately different types of insecticides for delay the development of resistance and better mosquito prevention and control.
