Objective: To explore the problems of recanalization and rebleeding after intracranial aneurysm embolization and the necessity of digital subtraction angiography (DSA) follow-up. Methods: One hundred and two patients with intracranial aneurysm (114 aneurysms, of them, 2 patients with multiple intracranial aneurysms, each with one small aneurysm did not coiled) were selected for endovascular embolization with Guglielmi detachable coil (GDC), electrolytical detachable coil (EDC), mechanical detachable spiral (MDS) or Matrix detachable microcoils and were followed-up by the DSA from January 1997 to January 2005. The mean follow-up period was 10.5 months (1 month to 6.5 years) after the procedures. They were compared with the immediate DSA images after the embolizations. Results: Endovascular coiling procedures were performed in 112 aneurysms. 100% occlusion was 51.79% (58/112) after the initial embolization, ≥ 95% occlusion was 33.04% (37/112), and < 95% occlusion was 15.17% (17/112). After embolization, 87 (77.68% ) patients the coils were stable, 6 patients with residual aneurysms (5.36%), and 19 aneurysms (16.96%) recanalized. Among the 90 aneurysms embolized with GDC or EDC, 14 (15.56%) recanalized. Among the aneurysms with 100%, ≥95% and < 95% occlusion, their recanalize rates after the procedures were 4.08%, 26.67% and 36.36%, respectively, and there were significant differences among them (P < 0.01). Nine recanalized aneurysms were reembolized with GDC, and rebleeding did not occur. Among 5 recanalized aneurysms, 1 aneurysm experienced rebleeding later. Of the 18 aneurysms embolized with MDS recanalization, 5 recanalized during the follow-up period. The aneurysms treated with Matrix detachable microcoils or Neuroform stents + Matrix detachable microcoils, the aneurysms were occluded completely on follow-up DSA, even the inital occlusions were nearly complete or incomplete. Conclusion: The recanalization of intracranial aneurysms is associated with the initial embolization and the embolic materials used. DSA follow-up should be emphasized, and additional coiling should be performed if the aneurysm is recanalized.

Objective To compare the clinical-pathology features between male breast cancer ( MBC) and female breast cancer(FBC)patients.Methods Clinical data of 37 MBC and 300 FBC patients admitted in the First Affiliated Hospital of Zhengzhou University from Jun .2003 to Jun.2013 was retrospectively reviewed . Results The ratio of MBC to FBC was 54:10000.The age of MBC patients ranged from 39 to 80 years with the median age of 62 years old, older than FBC patients(t=3.117, P=0.002).The percentage of invasive ducal carcinoma was much higher in MBC patients than in FBC patients (χ2 =7.535,P=0.023).MBC patients in clinically stage III and IV were more than FBC patients (χ2 =16.471,P=0.000).The positive rate of estrogen receptor(ER)was significantly higher in MBC patients than in FBC patients (χ2 =6.294,P=0.043).The posi-tive rate of human epidermal growth factor receptor-2 ( HER2 ) was lower in MBC patients than in FBC patients (χ2 =11.222,P=0.004).The main surgical method of MBC was modified radical mastectomy , and there was no breast-conserving surgery for MBC, while the surgical method of FBC was various (χ2 =7.720,P=0.021). Conclusion There are significant differences between FBC and MBC patients in clinicopathological features , surgical method and even prognosis , which were important to guide the treatment of MBC and FBC .

Objective To evaluate the curative effect of infection caused by peritoneal dialysis(PD) catheter. Methods Eighty patients with infections caused by peritoneal dialysis catheter were enrolled in this study and randomized into silver-containing hydrofiber dressing group and control group with 40 patients in each group. The control group was treated with iodophor and/or gentamicin and the treatment group with silver-containing hydrofiber dressings. The two groups were compared in terms of curative effect at the wounds and time for cure. Result The cure rate in the treatment group was significantly higher than that in the control group (P<0.05), and the cure time in the observation group was significantly shorter as compared to the control group. Conclusion Silver-containing hydrofiber dressing is effective in the treatment of PD catheter-induced infections , and it can shorten treatment duration and reduce the frequency of dressing change.

Objective To observe and analyze the changes of inflammatory cytokines levels in patients with progressive cerebral infarction (PCI ).Methods The patients with progressive cerebral infarction (progressive cerebral infarction group),the patients with non-progressive cerebral infarction(non progressive cerebral infarction group)and the healthy individuals(control group)were selected as the research subjects.Sixty individuals were included in each group.The levels of IL-8,hs -CRP,SAA of the research subjects were detected and observed. Results The levels of IL -8[(201.89 ±46.41)mg/L],hs -CRP[(16.55 ±4.49)mg/L],SAA[(20.65 ± 4.17 )mg/L]of the progressive cerebral infarction group were significantly higher than those of non -progressive cerebral infarction group[(132.02 ±40.26 )mg/L,(8.09 ±4.06)mg/L and (15.35 ±4.07 )mg/L).]The differ-ences were statistically significant (t=4.289,P=0.000;t=2.276,P=0.006 and t=2.269,P=0.031).Compared with the control group[(50.70 ±31.14 )mg/L,(0.70 ±0.11 )mg/L and (5.15 ±2.21)mg/L],the levels of IL-8, hs-CRP,SAA in the progressive cerebral infarction group and non -progressive cerebral infarction group were significantly higher on the first day (PCI group vs control:t=3.614,P=0.000;t=3.406,P=0.007;t=2.559, P=0.009;NPCI group vs control:t=3.602,P=0.000;t=3.181,P=0.009;t=1.520,P=0.026).Conclusion The changes of the inflammatory factors levels such as IL-8,hs-CRP,SAA have certain predicative value on the development of the PCI.

Objective To determine the immunophenotypic features of peripheral lymphocytes in adult patients with Epstein-Barr virus (EBV)-associated infectious mononucleosis (IM) and chronic active EBV infection (CAEBV).Methods Eighteen IM patients,12 CAEBV patients and 18 healthy donors were included.Lymphocyte subsets including CD3-CD+19 B cells,CD3-CD+16/56 NK cells,CD4+ and CD8+T cells in peripheral blood were measured by flow cytometry.The expression of activation markers (HLA-DR and CD38) on CD8+T cells and CD28 expression on T cells were also determined.Kruskal-Wallis H and MannWhitney U tests were used to compare variables among groups.Results IM patients had dramatically increased CD8+T cell counts than healthy donors (5.22 × 109/L vs 0.54 × 109/L,P ＜ 0.001).B cell counts moderately reduced in patients with IM than in healthy donors.No difference was found in absolute CD4+T cell and NK cell counts between IM and healthy donors.The levels of HLA-DR and CD38 on CD8+T cells significantly increased in IM patients compared with those in healthy controls.The intensity of CD28 on CD8+T cells significantly decreased,which was not seen on CD4+T cells.The median cell counts of B,NK,CD4+T and CD8+T subsets in CAEBV patients were 0.02 × 109/L,0.06 × 109/L,0.26 × 109/L and 0.21 ×109/L respectively,which were significantly lower than those in healthy donors (0.22 × 109/L,0.38 ×109/L,0.78 × 109/L,0.54 × 109/L) and IM patients (0.12 × 109/L,0.40 × 109/L,0.91 × 109/L,5.22 ×109/L).The positive rates of HLA-DR and CD38 on CD8+T cells in CAEBV patients were higher than those in healthy controls,but lower than those in IM patients.Conclusions The immunophenotypic pattern in adult patients with IM is characterized by a dramatic increase of extensively activated CD8+ T cells,a moderate reduction of CD+19B cells and no significant change of CD4+T cells and CD+16/56NK cells.CAEBV is featured by an immunosuppression status as demonstrated by significantly decreased B,NK,CD4+T and CD8+T subsets.

AIM: To evaluate the relationship between the medial rectus cells counts in concomitant exotropia and surgical results. METHODS: A total of 32 pieces of medial rectus muscle were collected for HE staining in this study, of which 18 pieces were from patients with concomitant exotropia and 14 pieces were from healthy individuals. A method of strabismus score was used to assess the operative effect.RESULTS: The difference of strabismus score before and after the operation in the intermittent exotropia group was significantly higher than that in constant exotropic group (P<0.01). Under light microscope, the loosen muscle fibers and the increased stromal components in the cross sectional area of medial rectus were observed in strabismic group. The muscle cells counts was obviously lower in strabismic group than in control group (P<0.01), which was related to the difference of strabismus score before and after the operation (P<0.05).CONCLUSION: The decreased medial rectus cells counts induce concomitant exotropia directly. It is the crucial causes of the bad surgical results.

Objective To evaluate the inhibition effects of shuanghuanglian injection powder and its active components on the activities of CYP1A,CYP 2D and CYP 3A in rats liver microsomes. Methods Three probe substrates including phenacetin for CYP1A,dextromethorphan for CYP2D and midazolam for CYP3A were incubated with shuanghuanglian injection powder and the active components (baicalin,phillyrin,forsythiaside A,lutin,chlorogenic acid,coffeic acid and lutiolin) in rat liver microsomes. Contents of three probe substrates were simultaneously determined by HPLC to evaluate the metabolic rates. Results Shuanghuanglian injection powder and baicalin inhibited the activities of CYP2D and CYP 3A, but didn 't affect CYP1A. The other active components showed no effect on CYP1A,CYP2D and CYP3A. Conclusion Drug-drug interactions may occur when combining shuanghuanglian powder injection with CYP2D and CYP 3A substrates and baicalin may be the effector substance responsible for the interactions.

Objective To explore the influence of Azithromycin on helper T lymphocyte cell(Th)1/Th2 in peripheral blood of children with bronchitic asthma.Methods Twenty-four asthmatic children and 20 healthy children were selected.Peripheral blood mononuclear cells (PBMC) were isolated from venous blood and made into cells suspension in aseptic condition.0.2 mg/L,0.1 mg/L,0.05 mg/L and 0 mg/L Azithromycin were added into the cultures in asthmatic group.The control group was not interfered with Azithromycin.The supernatant was collected after 48 h.The levels of IFN-?,IL-4 and IL-10 in the supernatant were determined by enzyme-linked immunosobent assay(ELISA).SPSS 11.5 software was used to analyze data.Results 1.The level of IL-4 produced from PBMC of asthmatic group was significantly higher than that of control group(P0.05).2.Azithromycin 0.1 mg/L more promoted the secretion of IL-4 than the other 3 concentrations(Pa0.05).3.Azithromycin 0.2 mg/L and 0.1 mg/L more increased the level of IL-10 than the control group(P0.05).Conclusions The routine drug level of Azithromycin(0.1 mg/L) had no effects on the imbalance of Th1/Th2 of asthmatic children,but could modulate the immunological function by up-regulating the level of IL-10.
