Objective To estimate the efficacy and safety of Voriconazole as antifungal prophylaxis of invasive fungal infection ( IFI) for malignant hematology patients. Methods The randomized controlled trials of Voriconazole treatment in invasive fungal infection for malignant hematology patients (ended in September 2014) were searched from Cochrane library, Medline, Embase, Pubmed, CBM, CNKI, Blood database. The meta analysis were performed by RevMan5.0. Results Ten literatures reported in 1 773 cases, in which there was significantly difference in effective rate between Voriconazole and other antifungal agents such as Amphotericin-B, Itraconazole, Micafungin and Fluconazole(P < 0.000 01); Four literatures indicated that there was significantly difference in adverse event rate between Voriconazole and amphotericin-B (P < 0.00 001); no significantly difference in adverse event rate between Voriconazole and amphotericin-B(P = 0.57); no significantly difference in adverse event rate between Voriconazole and Micafungin (P = 0.69); no significantly difference in adverse event rate between Voriconazole and Fluconazole (P = 0.70); Subgroup analysis indicated that adverse event rate between Voriconazole and Itraconazole is P=0.001, P = 0.17 respectively. Conclusion Voriconazole showed relative high efficient and low toxicity characteristics in treatment of malignant hematology accompanied by invasive fungal infection. But with its widely clinical application, the clinical value of Voriconazole needs to be further tested.

Objective Cervical lymph node enlargement may be attributed to inflammation or tumors .This study was to analyze the pitfalls in fine-needle aspiration cytology ( FNAC) of cervical lymph nodes and the measures for avoiding misdiagnosis of cervical lymph node lesions . Methods We retrospectively analyzed the data about 435 cases of FNAC in comparison with the results of corre-sponding tissue biopsies in cervical lymph nodes . Results Among the 435 cases, 7 showed disagreement between the results of cytolog-ic and histologic diagnoses, which included 5 males and 2 females, at the age of 41 to 71 (58.4 ±8.9) years.Six of the cases presented with local lymph node enlargement and 1 with generalized lymphadenopathy, all with enlarged lymph nodes palpable 1-4 cm in diameter . Based on the results of FNAC, 1 case of malignant lymphoma was misdiagnosed as lowly differentiated adenocarcinoma, 1 case of lympho-ma misdiagnosed as poorly differentiated metastatic carcinoma, 2 cases of lymphoma diagnosed as lymphoproliferation and recommended for biopsy, 1 case suggestive of malignant tumor without further classification, and 2 cases microscopically characterized and recommended for lymph node biopsy.Compared with the results of the biopsy, FNAC achieved a 99.3%coincidence rate of qualitative diagnosis (432/425), with a misdiagnosis rate of 1.6%(7/435). Conclusion FNAC plays a very important role in the initial identification of the nature of lymph node lesions and the type of tumors.Practiced puncture skills and intimate knowledge about the histopathological features, diagnostic criteria, and differential diagnosis of the lymphatic system disorders are essential for improving the diagnostic accuracy of FNAC .

Objective:
: This study analyzed the influence of p120-catenin (catenin [cadherin-associated protein], delta 1 [CTNND1]) on the malignant characteristics of glioma and elucidated the potential underlying mechanism.
Methods:
: The p120 expression level was assessed in the brain tissues of 42 glioma patients and 10 patients with epilepsy by using the immunohistochemical method. Meanwhile, quantitative polymerase chain reaction (QT-PCR) technology was employed to assess the expression of p120 in the brain tissues of 71 glioma patients and 13 epilepsy patients. LN229, U251, and U87 glioma cells were used for in vitro analysis and categorized into four treatment groups : siRNA-blank control (BC) group (no RNA sequence was transfected), siRNA-negative control (NC) group (transfected control RNA sequences with no effect), and siRNA-1 and siRNA-2 groups (two p120-specific interfering RNA transfection). p120 expression in these treatment groups was quantified by western blotting assay. The migratory and invasive capabilities of glioma cells were studied by wound healing assay and Transwell invasion assay, respectively, under different treatment conditions. MTT (3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide) assay and cell cycle and apoptosis assay were used to determine glioma cell proliferation and apoptosis, respectively. Enzymelabeled assay was performed to measure intracellular calcium ion concentration. Immunofluorescence assay was performed for determining microtubule formation and glioma cell distribution.
Results:
: Brain tissues of the glioma group exhibited a remarkable increase in the p120 expression level as compared to brain tissues of the nontumor group (p<0.05). Furthermore, a strong positive correlation was noted between the malignancy degree in glioma brain tissues and p120 expression in Western blotting (r=0.906, p<0.0001) and QT-PCR (F=830.6, p<0.01). Compared to the BC and NC groups, the siRNA transfection groups showed a significant suppression in p120 expression in glioma cells (p<0.05), with a marked attenuation in the invasive, migratory, and proliferative capabilities of glioma cells as well as an increase in apoptotic potential (p<0.05). Enzyme-labeled assay showed a remarkable increase in calcium concentration in glioma cells after siRNA treatment. Immunofluorescence assay revealed that the microtubule formation ability of glioma cells reduced after siRNA treatment.
Conclusion
: p120 has a pivotal involvement in facilitating glioma cell invasion and proliferation by potentially modulating these processes through its involvement in microtubule formation and regulation of intracellular calcium ion levels.
