Objective To study the clinical application of the lung lesion biopsy through helical CT-guided fine needle aspiration. Methods 44 cases of lung lesions were pathologically biopsy diagnosed through helical CT-guided fine needle aspiration. Results All 44 lung lesions were successfully conducted biopsy through CT-guided fine needle aspiration, and the pathological confirmed diagnosis rate was 98%. Conclusion With high diagnosis rate, CT- fine needle aspiration is clinically applicable and the complication is rare. It is easily-operated, safe and economical.

AIM: To observe the changes of plasma content of Glu-plasminogen (plasmin, Pln) in patients during blood coagulation and/or fibrinolytic system activation. METHODS: Using specific McAb to antigenic determinant in NH 2 terminal (1-65 aa) of Pln and specific McAb to antigenic determinant in heavy chain of plasminogen, the sandwiched ELISA method was established to detect Glu-plasminogen and total plasminogen in human plasma collected from 220 normal controls and 40 patients after heart surgery. RESULTS: The average total plasminogen was (231.8?62.1) mg/L and average Glu-plasminogen was (231.9?45.8) mg/L in 220 normal controls, the ratio of Glu-plasminogen to total plasminogen (G/P) was 0.91. The ratio of Glu-plasminogen [(152.4?68.1) mg/L] to total plasminogen [(268.9?73.3) mg/L] in 40 patients after heart surgery was significantly lower than that in normal controls ( P

Objective To analyze the correlationship of ACE I/D gene polymerphisms with the anti-hypertensive efficacy of irbesartan among essential hypertension (EH) patients in Yunnan han people.Methods One hundred EH patients hypertension were treated with irbesartan 150mg once daily for 4 weeks,and anti-hypertensive efficacy were monitored during the treatment.Results There was a significant difference between anti-hypertensive efficacy of irbesartan among different genotype groups,DD group ＞ID group ＞Ⅱ group (P ＜ 0.05) Conclusions There is different therapy responsiveness in diffenent genotypes.ACE I/D polymorphism may be an important hereditary factor that impacts the efficacy of irbesartan.

Objective To compare the therapeutic effects of recurrent pterygium treated by with corneal limbal autograft con -junctival transplantation combined with mitomycin C and amniotic membrane transplantation combined with mitomycin C .Methods A total of 153 eyes of 153 cases with recurrent pterygium were divided into 2 groups ,A group :97 eyes who treated with amniotic membrane transplantation combined with mitomycin C ,B group :56 eyes treated with corneal limbal autograft conjunctival trans -plantation combined with mitomycin C ,follow up 12 months after operation .Results 12 eyes had recurrence in A group ,the recur-rent rate was 12 .37% ;5 eyes had recurrence in B group ,the recurrent rate was 8 .93% ,there was no significant different between 2 groups(P> 0 .05) .Conclusion This study indicates amniotic membrane transplantation or corneal limbal autograft conjunctival transplantation combined with mitomycin C can effectively reduce the recurrent rate of recurrent pterygium ,which are safe and ef-fective method .

AIM:To analyze the effect 17?-estradiol on activated macrophages and possibility of being a target of screening drugs for endometriosis. METHODS: Using scanning electron microscope, the surface of macrophages was observed. Nitric oxide (NO) in supernatant was determined by Griess's reagent. TNF-? was measured by MTT via L929 cells. Using Fluo-3/AM, i was measured by laser scanning confocal microscopy (LSCM). RESULTS: (1) Increased size, extension of more microvilli, expression of retraction fibers and elaboration of membrane ruffles were detected in 17?-estradiol treated macrophages. (2) 17?-estradiol induced NO release from peritoneal macrophages. (3)The more TNF-? was made by macrophages under the induction of 17?-estradiol. (4)Intracellular Ca 2+ elevated 39.8% in peritoneal macrophages after 17?-estradiol (100 nmol/L) treatment. CONCLUSIONS: Macrophages were activated by 17?-estradiol at a certain concentration. Activated macrophages by 17?-estradiol may participate in endometriosis and may be a target of screening drugs for endometriosis.

AIM To study the effect of 17?-estradiol(E 2) on apoptosis of macrophages at certain concentration.METHODS Fluorescent microscopy and scanning eletron microscopy(ESEM) were used to detect apoptosis changes of macrophages induced by E 2 at relatively high concentration and intracellular Ca 2+ and matochontrial transmembrane potential were examined by laser scanning confocal microscopy(LSCM). RESULTS Apoptosis of macrophages was induced by high concentration of E 2 (≥1 ?mol?L -1). Intracellular Ca 2+ elevated and matochontrial transmembrane potential decreased after E 2 treatment. CONCLUSION Apoptosis of macrophages is induced by certain concentration of E 2 (≥1 ?mol?L -1) and this may be related to elevated intracellular Ca 2+ and decreased matochontrial transmembrane potential.
