Objective To analyze the content of polycyclic aromatic hydrocarbons (PAHs) in mainstream smoke of 20 brands of Chinese cigarette. Methods Mainstream smoke of 20 brands of Chinese cigarettes were collected by ASM51 smoking machine. Both tar and nicotine were analysed in the same time. Nine kinds of PAHs, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(g, h, j)perylene and dibenzo(a, h)anthracene, in mainstream smoke from each brand were determined with HPLC. Results Total PAHs ranged from 404.1 to 1 085 ng per cigarette with an average of 714.8 ng per cigarette. Non-carcinogenic PAHs accounted for 93% of total PAHs. Carcinogenic PAHs ranged from 49.4 to 117.7 ng per cigarette, averaging 89.4 ng per cigarette. Content of tar, not nicotine, was significantly related to either total PAHs or carcinogenic PAHs. Conclusion Significant correlation between tar and PAHs suggests that tar may be a predictor of carcinogenic PAHs in mainstream smoke of Chinese cigarettes and a parameter to assess the impact of Chinese cigarettes on health.

Objective To investigate the preventive effect of low molecular weight heparin or tranexamic acid in the rabbits with hypercoagulation induced by impact injury and intravenous infusion of the endotoxin. Methods Combination of impact injury and endotoxin was created by strike on rabbit chest with type BIM-Ⅱ biological impact machine and injection of endotoxin via vein.Thirty-two male New Zealand rabbits were divided into four groups in a completely random design as follows:impact injury combined with endotoxin without treatment group(control group),treatment with low molecular weight heparin(L group),treatment with tranexamic acid(TA group),and treatment with low molecular weight heparin and tranexamie acid(L+TA group).The changes of interleukin-1β(IL-1β)and interleukin-6(IL-6)were observed by using the enzyme-linked immunosorbent assay;changes of antithrombin-Ⅲ(AT-Ⅲ)activity,tissue factor(TF)and tissue factor pathway inhibitors(TFPI)were detected by the chromogenic substrate method chromozym P:the content of fibrinogen was observed by coagulation analyzer.The lung and kidney were removed from the experimental animals at 24 hours post impact injury forhistopathologic observation. Results In the control group,the activity of AT-Ⅲ was decreased obviously.while the content of fibrinogen and the activity of TF and TFPl were increased,with formation of the thrombosis in the kidney after injection of PLS.Compared with control group,the activity of TF and the content of IL-1β and IL-6 were reduced but the TFPI was increased in the L group,which resulted in a decrease of TF/TFPI ratio.with decrease of formation of the micro-thrombosis in the organs.The content of IL-1β and IL-6 in the TA group were reduced,which was still higher than that in tIle L group.In the TA group.the activity of IF and TFPI Was lower than that in the L group and control group,with higher TF/TFPI ratio than the L group.The frequency of thrombosis increased in pulmonary artery and other important organs.The content of IL-1β and IL-6 in the L+TA group wag lower than that in the L group.In the L+TA group.the activity ofTF was lower than that inthe L group and control group,but the activity of TFPI was higher than that in the L group and control group.with lower TF/TFPI ratio than the L group.There found no increase of thrombus in the pulmonary arterial and other important organs. Conclusions Besides anticoagulation function,the low molecular weight heparin can inhibit the inflanunation reaction,reduce the release of TF and attenuate the coagulation reaction.On the basis of treatment with low molecular weight heparin,application of the tranexamic acid will not lead to the formation of thrombus,but the only use of the tranexamic acid would have the contrary results.The rtsults of the study provide a theoretical and experimental basis for clinical diagnosis and prevention of hypercoagulation induced by injury and infection.

BACKGROUND: Growth factor can promote the development of collateral vessels. The synergistic effects of multiple factors are obvious. Many kinds of growth factors are enriched in bone marrow serum. OBJECTIVE: To determine effects of bone marrow serum on angiogenesis in chick chorioallantoic membranes following vascular intimal injury. METHODS: A total of 70 fertilized chick eggs were incubated at (37.5±0.5) ℃ and made a window in every egg at day 7. The survival chick embryos were randomly divided into six groups: normal saline group, normal blood serum group, normal bone marrow serum group, blood serum of rabbit suffered with vascular intimal injury group, bone marrow serum of rabbit suffered with vascular intimal injury group and vascular endothelial growth factor group (n=10), which were respectively treated with 5 μL rabbit normal blood serum, 5 μL rabbit normal bone marrow serum, 5 μL blood serum of rabbit suffered with vascular intimal injury, 5 μL bone marrow serum of rabbit suffered with vascular intimal injury, 5 μL normal saline and 0.3 μg vascular endothelial growth factor in chick chorioallantoic membranes, for 3 consecutive days. Pictures were taken by a digital camera, and the total number of the vessels around the disc was measured. RESULTS AND CONCLUSION: The total numbers of vessels in normal bone marrow serum group and blood serum of rabbit suffered with vascular intimal injury group were obviously higher than that of normal blood serum group. Large and middle vessels were obviously proliferated. Large and middle vessels were more observed in the blood serum of rabbit suffered with vascular intimal injury group. These indicated that normal bone marrow serum can stimulate angiogenesis in models of chick chorioallantoic membranes. Compared with vascular endothelial growth factor, both the normal bone serum and the bone marrow serum of rabbit suffered from vascular intimal injury were more effective in angiogenesis. The blood serum and bone marrow serum from vascular intimal injured rabbit at day 7 can significantly promote angiogenesis in chick chorioallantoic membranes, which was better than the vascular endothelial growth factor group.

Objective To evaluate the efficacy and safety of the improved percutaneous balloon mitral valvuloplasty (PBMV) in elderly patients with mitral stenosis. Methods Elderly patients with severe mitral stenosis received an improved PBMV which included a modified way of atrial septal puncture and technique across the mitral valve. The left atrial pressrue (LAP), mean pulmonary pressure (MPA), mean gradient across the mitral value (MPG) and mitral valve area (MVA) were recorded and compared before and after the operation. Long term follow up were made. Results After operation, the LAP decreased [(25.3±6.7) mm Hg vs.(16.4±5.8) mm Hg,1 mm Hg=0.133 Kpa], MPG decreased [(17.6±6.7) mm Hg vs.(6.8±2.9) mm Hg], MPA decreased [(38.6±12.1) mm Hg vs. (29.2±9.8) mm Hg], MVA increased [(1.05±0.22)cm2 vs.(1.61±0.38)cm2] and the New York heart association heart function classification improved. The follow-up result showed that the effect of PBMV was constant. Conclusions Improved PBMV may be an effective and safe measure for patients with mitral stenosis.
