Objective To investigate the efficacy and safety of different strategy of antithrombotic therapy in elderly patients with atrial fibrillation (AF) and coronary disease.Methods 224 inpatients and outpatients with AF and coronary disease whose mean follow-up time was 2 years,were divided into warfarin group,warfarin combined with antiplatelet drug(aspirin or clopidogrel) group,antiplatelet drug(aspirin or clopidogrel) group and control group.The thromboembolic event rate and adverse events incidence were observed in different groups.Results The risk of thromboembolic events,particular emerging risk of cerebral infarction in the control group(12.50 ％) was significantly higher than other groups (P＜ 0.05).Thrombotic event rates in warfarin + single joint group(2.78％) was lower than other groups(warfarin group 4.29 ％,single joint group 5.81％),but there was no significant statistical difference.The overall risk of bleeding in the control group (3.13 ％) was significantly lower than other antithrombotic group (P＜0.05).The incidence of skin bruising in single joint group was lower than other antithrombotic groups,the overall bleeding risk,especially gasfrointestinal bleeding in warfarin+ single joint group was significantly higher than other groups (P＜ 0.05).Conclusion Elderly patients with coronary heart disease and atrial fibrillation need antithrombotic therapy to prevent thrombotic events.Using warfarin alone or warfarin combined antiplatelet drug does not lead to serious bleeding events,but generally bleeding risk should be attracted more attention.

Chronic active Epstein - Barr virus infection(CAEBV) is an uncommon outcome of EBV infection and may present as severe of fulminant syndrome with high- mortality. It is characterized by chronic or recurrent infectious mononucleosis-like symptoms persisting over a long time and by an unusual pattern of anti-EBV antibodies. Although it occurs in immunocompetent individuals, a number of subtle immunologic defects have been reported in patients with CAEBV. Up to now, there are still no diagnostic criteria of CAEBV in China,so the author introduce it with respect to its diagnosis,history,pathogenesis and therapeutic approaches.

Ptosis is one of the most common diseases in oculoplastics. Surgical treatment is the only way to correcting ptosis. Most of doctors paid special attention to surgical technique, rather than to some related issues of operation. Timing is crucial for ptosis surgery. Both cosmetic and function need to be considered for a success surgery, the evaluation of extraocular muscle disorder is impor- tant for surgical result and postoperative complications.

Objective To investigate the role of infiltrating inflammatory cells in photoaging process by comparing the type and number of these cells in sun-exposed and-unexposed skin.Methods The expression of CD3,CD45RO and CD68 were detected by immunohistochemieal staining in 46 paraffin-embeded skin samples from the extensor forearms(sun-exposed)and upper-inner arms(sun-unexposed) of 23 healthy female volunteers.The number of positive cells in sun-exposed and -unexposed sites was counted and statistically tested by paired samples t test,and Pearson correlation analysis was performed to assess the relationship between the number of positive cells and age of these volunteers.Results The number of cells positive for CD3,CD45RO and CD68 per square millimetre in sun-exposed skin was significantly higher than that in sun-unexposed skin(48.91±13.173 vs.40.61±11.571,46.83±12.915 vs.38.00±10.109,85.43±22.346 vs.73.48±16.208,respectively,P<0.01 or 0.05).The number of cells positive for CD3 and CD45RO increased significantly with age (r=0.557,0.555,respectively,both P<0.01) in the sun-exposed skin but not in sun-unexposed skin,and the number of CD68-positive cells was uncorrelated with age in either sunexposed or -unexposed skin.Conclusion T lymphocytes and macrophages may play a role in the process of photoaging.

Objective Construct the lentiviral AQP1 vector and explore whether it can transfect the myocyte or not,then test the law of the AQP1 expression and the edema in the successfully transducted myocytes after cardiopulmonary bypass in sheeps.Methods Design cleavage primer according to ovine AQP1mRNA,clone it into expressing vector and transducated into the 293T cells with other packing vectors to produce the lentiviral AQP1 vector,then test the virus titer.36 adult healthy sheeps are randomly divided into blank or AQP1-lentiviral transfected group,blank or AQP1-lentiviral vector suspension was injected in the ventricle tissue of healthy adult sheeps during cardiopulmonary bypass and take specimen in different time points (2,6,12,24,48,72 h)after extracorporeal circulation,3 in each group.Realtime-PCR WesternBlot ELISA FACS immumofluorescent and Dry/Wet methods are emploied to detect the expression of AQP1 and the according degree of edema.Results lentiviral AQP1 vector was successfully construced and transducated into the myocytes.The tranducated groups have the same trend of AQP1 of expression and cardiac edema after cardiopulmonary bypass compared to the blank vector group,but the degree is heavier(P ＜ 0.05).Conclusion Lentivral AQP1 vector can successfully transfect the myoctyes,and the overexpressed myocardial tissue have the same trend of AQP1 expression and edema after cardiopulmonary bypass,but with a heaver degree.The expression of aquaporins was positively relevant to the edema.

Objective To observe the expression changes of CD34 and M30 in skin homogenate from a mouse model of scleroderma after irradiation with different doses of UVA1, and to investigate the effect of UVA1 phototherapy on vascular endothelial cell function in scleroderma. Methods The experimental mouse models of scleroderma were established by the injection with bleomycin and randomly divided into model control group (n = 10), UVA1 irradiation group (n = 30) and unirradiated group (n = 10). The UVA1 irradiation group was further equally divided into 3 groups, HD-UVA1 group irradiated with UVA1 at 100 J/cm2, MD-UVA1group with UVA1 at 60 J/cm2, and LD-UVA1 group with UVA1 at 20 J/cm2; phototherapy was performed thrice weekly for 10 weeks followed by the sacrifice of mice. The mice in model control group were killed immediately after the establishment of models, and the mice in unirradiated group received no irradiation after the establishment of models and were maintained till the killing of mice in UVA1 irradiation groups. Skin specimens were obtained from the bleomycin-induced scleroderma lesions of mice and separated into two parts, one was subjected to histopathological examination, and the other one was used to prepare skin homogenate for the detection of CD34 and M30 content with ELISA assay. Results After 30 sessions of treatment with UVA1,the softening and thinning of sclerotic skin were seen by the naked eye, with the most obvious changes in HDUVA1 group; pathological examination revealed a reduction in dermal thickness and the presence of hair follicular structures in subcutaneous fat tissue with no obvious proliferation of collagen in these mice. Compared with the mice in model control group and unirradiated group, there was an increase in CD34 and decrease in M30 content in skin homogenate from UVA 1-irradiated mice, with the most marked changes in mice irradiated with UVA1 at 100 J/cm2. The concentration of CD34 and M30 in skin homogenate from unirradiated group and model control group was significantly different from that in HD-UVA1 group (22.25 ± 8.91 μg/L and 31.97 ±17.97 μg/L vs. 72.39 ± 13.04 μg/L, 162.41 ± 58.00 U/L and 195.71 ± 71.09 U/L vs. 38.06 ± 19.89 U/L, all P ＜ 0.01 ). Additionally, significant differences were observed between the three UVA1 groups in the concentration of CD34 and M30 (F = 21.23, 15.32, respectively, both P ＜ 0.01 ). Conclusions UVA1 phototherapy could up-regulate the expression of CD34 but down-regulate that of M30 in skin homogenate from the mouse model of scleroderma, and the effect is correlated with the intensity and cumulative dose of irradiation.
