Objective To explore how to improve the sensitivity and specificity of CT cisternography (CTC) examination.Methods The clinical data of 20 cases of CTC in detecting cerebrospinal fluid rhinorrhea were analyzed,and the influence of continuous dripping of fluid and the filling time of subarachnoid space upon the image quality were observed.Results Nineteen cases of active cerebrospinal fluid rhinorrhea were found with CTC,and the fistula sites were determined by CTC.Eighteen cases received operation which confirmed the fistula sites.One case was found with no active fistula site.According to the image of ethmoid sinus leaks results,7 cases had better image quality in 9 cases whose subarachnoid space filling time was longer than or equal to 10 min.One case had better image quality in 6 cases whose subarachnoid space filling time was shorter than 10 min.There was significant difference (P =0.0406).Conclusion To raise the positive rate of CTC,the position of active fistula should be maintained and keep the time between the injection and scan longer than or equal to 10 min,which help to get better image quality.

AIM: To investigate the effect of advanced glycosylation end products on the expression of receptor for advanced glycosylation end products in human monocyte-derived dendritic cells. METHODS: Monocytes were purified (over 98%) using anti-CD14+ microbeads. After 8 d culture in RPMI-1640 medium containing rhGM-CSF (100 ?g/L) and rhIL-4 (50 ?g/L), immature MDCs were derived, then exposed to AGE-BSA (0 or 200 mg/L) for 24 h. Expression of RAGE was semi-quantified by RT-PCR and Western blotting. At the same time, supernatants were collected. IFN-? and IL-12 were analyzed by ELISA. RESULTS: mRNA and protein of RAGE incubated by 200 mg/L AGE-BSA was higher than that in control at 24 h. Treatment of DCs with AGE-BSA resulted in about two-fold increase in the expression of RAGE (P

AIM: The purpose of this study is to investigate the mechanisms related to oxidized low-density lipoprotein(ox-LDL) and dendritic cells(DCs) in the process of atherosclerosis.METHODS: Human DCs were prepared from human CD14~+ peripheral blood monocytes using rhGM-CSF((100 ?g/L)) and rhIL-4(40 ?g/L).Cells were incubated with(100 mg/L) native or oxidized LDL for 72 h.The formation of foam cells was investigated by electron microscopy and oil red O staining.Phenotypic and immune functional assays were used with FACS,FITC-dextran phagocytosis,allogeneic mixed T lymphocytes reaction and secretion of Th1/Th2(IL-12/IL-2) cytokines were also conduced.RESULTS: DCs treated with ox-LDL,but not native LDL were induced into foam cells after cultured for 72 h.Compared with native LDL,ox-LDL-treated DCs were less potent in FITC-dextran phagocytosis.ox-LDL promoted allogeneic T cells proliferation.Moreover,ox-LDL upregulated CD80(72.4? 9.6 vs 89.5?10.1,P

OBJECTIVETo compare the contents and composition of volatile oil of Wenyujin (steamed root of Curcuma wenyujin) Wenezhu (steamed rhieome of Curcuma wenyujin) and Pianjianghuang (rhizome of Curcuma wenyujin).

METHODThe volatile oils of three herbal medicines obtained by steam distillation were determined according to the method described in the appendix XD in Chinese pharmacopoeia and identified by GC-MS.

RESULTThe average contents of volatile oil of Wenyujin, Wenezhu and Pianjianghuang were 0.56, 1.99 and 0.94 microL x g(-1), respectively. A total of 60 compounds were identified by GC-MS. The amounts of chemical components separated and identified in Wenyujin, Wenezhu and Pianjianghuang were 41, 41 and 40, respectively. Three medicines share a great deal of similarity, chemically and genetically. Low boiling point essential oil compositions Wenyujin and Wenezhu were similar. While the higher boiling point essential oil compositions of Wenyujin and Wenezhu were similar. And the essential oil compositions of Wenyujin and Pianjianghuang were distinct.

CONCLUSIONAlthough coming from the same origin, the composition of essential oil from different part of the plant or various process were discrepant, which lead to rather distinct clinical efficacy.

Objective To evaluate the feasibility and safety of supratotal resection of frontal or temporal lobe glioblastoma by the postoperative cognitive function and overall survival. Methods The clinical data of patients with frontal or temporal lobe glioblastoma and treated from January 2010 to January 2015 were analyzed retrospectively.The patients underwent supratotal resection of glioblastoma after March 2012(trial group, 33 cases). Before March 2012, the patients underwent total resection of glioblastoma(control group,28 cases).The Montreal cognitive assessment(MoCA)scores before operation and the 7th day after operation were used to evaluate the security, while overall survival was used to evaluate the feasibility. Variance analysis of repeated measurement quantitative data was used for the statistical analysis of the results. Multivariate Cox model was used as a method to estimate the independent association of a variable set with overall survival. Survival time observation was plotted by the Kaplan-Meier analysis,starting from the data of surgery.Results The MoCA scores in control group at the 7th day after operation were significantly lower than those before operation:(25.39 ± 3.04)scores vs.(26.67 ± 2.19)scores, t = 4.446,P < 0.05. The MoCA scores in trial group at the 7th day after operation were significantly lower than those before operation:(21.93 ± 4.46)scores vs.(25.39 ± 3.04) scores,t = 3.485,P < 0.05. The survival analysis of Kaplan-Meier method showed that age, surgical method and preoperative KPS scores were statistically significant (P < 0.05). Cox regression analysis showed that the choice of surgical method and preoperative KPS was 0.286 and 0.965,respectively.The risk of death in control group was 0.286 times of that in trial group.The survival time of trial group was better than that of control group.Conclusions The cognitive function of patients with frontal or temporal glioblastoma may have a certain degree of decline after tumor resection or supratotal resection.Supratotal resection could represent a promising strategy that can impact on outcome in glioblastoma patients. Supratotal resection could be a factor influencing survival.

Purpose: NUF2 has been implicated in multiple cancers recently, suggesting NUF2 may play a role in the common tumorigenesis process. In this study, we aim to perform comprehensive meta-analysis of NUF2 expression in the cancer types included in the Cancer Genome Atlas (TCGA). Materials and Methods: RNA-sequencing data in 31 cancer types in the TCGA data and 11 independent datasets were used to examine NUF2 expression. Silencing NUF2 using targeting shRNAs in hepatocellular carcinoma (HCC) cell lines was used to evaluate NUF2’s role in HCC in vitro and in vivo. Results: NUF2 up-regulation is significantly observed in 23 out of the 31 cancer types in the TCGA datasets and validated in 13 major cancer types using 11 independent datasets. NUF2 overexpression was clinically important as high NUF2 was significantly associated with tumor stages in eight different cancers. High NUF2 was also associated with significantly poorer patient overall survival and disease-free survival in eight and six cancers, respectively. We proceeded to validate NUF2 overexpression and its negative association with overall survival at the protein level in an independent cohort of 40 HCC patients. Compared to the non-targeting controls, NUF2 knockdown cells showed significantly reduced ability to grow, migrate into a scratch wound and invade the 8 μm porous membrane in vitro. Moreover, NUF2 knockdown cells also formed significantly smaller tumors than control cells in mouse xenograft assays in vivo. Conclusion NUF2 up-regulation is a common feature of many cancers. The prognostic potential and functional impact of NUF2 up-regulation warrant further studies.
