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: The study aimed to verify the effects of arsenic trioxide in combination with aspirin on angiogenesis of human gastric cancer xenografts in nude mice. METHODS: Experiments were performed at the Laboratory of Pathology, Xuzhou Medical College from September 2006 to July 2007. A total of 36 male BALB/C-nu/nu nude mice aged 4-6 weeks, weighting 18-22 g were selected. Human gastric cancer cell strain SGC-7901 were purchased from Shanghai Institute of Biology of Chinese Academy of Sciences. Thirty-six nude mouse models of cell strain SGC-7901 lateral armpit subcutaneously transplantation tumor were established and randomized into a control group, a aspirin group, a arsenic trioxide group and a combination group with nine in each group. Seven days after inoculation, nude mice were intraperitoneally administrated with drugs. Nude mice in the control group were treated with sterile saline (0.2 mL/d); Mice in the aspirin group were administrated with aspirin 0.3 g/(kg?d); Mice in the arsenic trioxide group received 2.5 mg/(kg?d); Mice in the combination group were administrated with 2.5 mg/(kg?d)plus aspirin 0.3 g/(kg?d), successively for 14 days. Immunohistochemical method (SP kit) was used to detect the expression of cycloxygenase-2 (COX-2) and CD34, and count microvessel density (MVD). Western-blotting was used to detect the expression of IKK?, I?B, nuclear factor (NF)-?B and vascular endothelial growth factor (VEGF). RESULTS: A total of 27 male BALB/C-nu/nu nude mice were included in the final results. Seven days after inoculation, 1 mm tumor was formed on the back of 31 nude mice. One mouse respectively died in the arsenic trioxide group and the combination group. One mouse died and one loss in the aspirin group. Compared to the aspirin group, arsenic trioxide group and control group, expressions of IKK?, NF-?B and VEGF decreased in the combination group (P

Colorectal cancer is a common malignant tumor in the gastrointestinal tract, with the characteristics of high morbidity and mortality. Studies have shown that the occurrence and development of colorectal cancer is closely related to the abnormal activation of Wnt signaling pathway. Abnormal expression of β-catenin in Wnt pathway is found both in the cytoplasm and nucleus of tumor cells. Different drugs can target the Wnt signaling pathway and its upstream and downstream related factors to inhibit or suppress the development of colorectal cancer. We review the components of Wnt signaling pathway, and the correlation between Wnt signaling pathway and colorectal cancer. Then, we summarize the current status of drug research targeting the Wnt signaling pathway in colorectal cancer. Finally, the challenges and prospects of these methods and drugs were briefly summarized.

Objective: To investigate the trends in incidence, mortality and disease burden of prostate cancer among residents at ages of 60 years and older in Zhangjiagang City, Jiangsu Province from 2006 to 2022, so as to provide insights into improvements in the prostate cancer control strategy. Methods: The incidence and mortality of prostate cancer among residents at ages of 60 years and older in Zhangjiagang City from 2006 to 2022 were collected from the Chronic Diseases Monitoring and Management System in the National Health Information Platform of Zhangjiagang City, and the crude incidence and mortality of prostate cancer were calculated and standardized to data from the sixth national population census in China in 2010. Based on the disease burden of prostate cancer captured from the 2019 Global Burden of Disease Study datasets, the years of life lost due to premature death (YLL) and years of life lived with disability (YLD) and disability-adjusted life years (DALY) due to prostate cancer were measured, and trends in incidence, mortality and disease burden of prostate cancer were analyzed using average annual percent change (AAPC). Results: The crude incidence, standardized incidence, crude mortality, standardized mortality, crude DALY rate and standardized DALY rate of prostate cancer were 89.85/105, 83.87/105, 32.31/105, 25.45/105, 546.39/105 and 483.50/105 among residents at ages of 60 years and older in Zhangjiagang City from 2006 to 2022, which all appeared a tendency towards a rise (AAPC=5.346%, 4.219%, 6.648%, 3.697%, 4.198% and 2.200%, all P<0.05). The crude incidence, mortality and DALY rate of prostate cancer all appeared a tendency towards a rise with age (all P<0.05), with a tendency towards a rise seen for the crude incidence of prostate cancer among residents at ages of 60 to 64 years, 65 to 69 years and 70 to 74 years (AAPC=4.888%, 8.086% and 3.005%, all P<0.05), and a tendency towards a rise for the crude mortality and DALY rate among residents at ages of 80 years and older (AAPC=10.243% and 9.693%, both P<0.05). Conclusion The incidence and mortality of prostate cancer showed a tendency towards a rise among residents at ages of 60 years and older in Zhangjiagang City from 2006 to 2022, and the disease burden due to prostate cancer continued to increase, with a more remarkable increasing tendency seen for the incidence of prostate cancer among residents at ages of 60 to 74 years and for the mortality among residents at ages of 80 years and older.
