Methods We summarized the experience in the application of PMMA in prosthesis for 8 years. 1155 patients were involved in the artificial eye custom-made program. The artificial eye was individually prepared based on the patient's condition and characters of the healthy eye.Results PMMA artificial eye associated with hydroxyl apatite implantation gave good cosmetic results with good motility, and there was no rejective reaction. The artificial eye was almost same to the real one in color and transparency. Conclusion It is suggested that PMMA is one of the best materials for manufacture of artificial eye at present.

Objective To analyse the neuropsychological changing of nonfluent aphasia frontotemporal dementia (nf-FTD) with the FDG-PET, MRI and fMRI. Methods The language and other cognitive function were dynamically estimated by standard neuropsychological assessment which modified by Chinese. Compared with FDG-PET and fMRI, the relationship between the neuropsychologieal changing and the cortex function was studied. Results All the 5 patients met the criteria of nf-FTD by Association for Frontotemporal Dementias, with core syndrome and other supptted syndrome. And still they had the good word reading, calculation by pen, and the un-speechmemory. And they also had the related well living ability. They all had the related cortext metabolism support. Conclusions nf-FTD patients preserve the word reading, visuapacial ability and calculation by pen. These can help us to give the effective advise about the patients training and caring and to give them the chance to show their real social skill.

Objective Standard neuropsychological assessment plus structural and functional imaging were used in accurate diagnosis of Benson's syndrome (posterior cortical atrophy).Method Serial neuropsychological screening and integrative assessments of visual spatial function, 3D structural MRIimaging and functional FDG-PET imaging were used in two cases of Benson' s syndrome.Results The clinical signs were agnosia, optic ataxia, apraxia, alexia, agraphia and prosopagnosia.MRI imaging revealed bilateral parietal and occipital lobe atrophy.FDG-PET imaging revealed low metabolism in the posterior cortex.The agraphia was constructive: the words were correct but written in the wrong location.Conclusion Standard neuropsychological assessments can recognize the disease nature.When combined with the structural and functional imaging, a correct diagnosis of Benson's syndrome can be made.

OBJECTIVETo evaluate the Chinese language version of the appraisal questionnaire (AQ) for HIV/AIDS (HIV positive persons).

METHODSThe scale was translated and adapted into Chinese and then reversely translated into English. The internal consistency reliability, structural validity, differential validity and predictive validity were evaluated by prevalence study in the city of Guangzhou.

RESULTSCronbach's alpha coefficient achieved a value ranged from 0.530 to 0.886, with satisfied predicted validity. The regression equation accounted for 24.4% of variance in anxiety, and all factors of cognition accounted for 11.4% of variance, among all factors, only factor one had significant influence on anxiety (t=3.838, P<0.001); the regression equation accounted for 38.6% of variance in depression, and all factors of cognition accounted for 26.0% of variance. Factor I and factor II had significant influence on depression (t=5.707, P<0.001; t = -2.876, P<0.01). The results of differential validity suggested the mean scores of factor III were lower in the group with lower education level and monthly salary. Meanwhile, the persons with monthly salary under 300 yuan RMB had higher mean score of factor I, and the persons with lower academic degree had lower mean score of factor II. The principal-components factor analysis yielded three factors with common factor larger than 1.0, which were threat, challenge and controllability; and the three factors accounted for 62.23% of the total variance.

CONCLUSIONThe AQ Chinese version attained satisfactory reliability and validity. Even considering some essential explanatory words for the Chinese version, the scale might be attempted to use in the population with HIV in our country.

OBJECTIVETo explore the role of X-linked inhibitor of apoptosis protein (XIAP) in the fibronectin (Fn)-adhesion mediated drug resistance of HL-60 cells.

METHODSCulture plates were coated with Fn and bovine serum albumin (BSA) (as control), respectively. Colorimetric CCK-8 assay was used to determine the effects of Fn on the cytotoxicity of DNR to HL-60 cells. Intracellular DNR accumulation was assayed with flow cytometry. Reverse transcription-PCR and Western blot were used to examine the mRNA expression and XIAP, bcl-2, MRP and mdr1 proteins, respectively. HL-60 cells were added to Fn coated Culture plates. The fully phosphorothioate antisense oligonucleotide (AS-ODNs) and the control ODNs of XIAP were delivered into HL-60 cells in the form of liposome-ODN complexes. IC(50) was calculated by linear regression of survival percent versus drug concentration.

RESULTSHL-60 cells adhered to Fn-coated plates had a significant survival advantage over those grown on BSA coated plates and in suspension when exposed to DNR, the IC(50) of Fn group being significantly higher than that of BSA group and suspension group (0.526 micromol/L vs 0.132 micromol/L, 0.123 micromol/L, respectively, P < 0.05). XIAP was up-regulated significantly in Fn group compared with BSA group and suspension group (P < 0.05), whereas there was no difference in the expressions of bcl-2, MRP and mdr1 among the three groups (P > 0.05). The intracellular concentration of DNR in Fn-adhered HL-60 cells was similar to that in BSA group and suspension group (P < 0.05). AS-ODNs of XIAP down-regulated the XIAP expression in Fn-adhered HL-60 cells. In addition, AS-ODNs sensitized HL-60 cells to the cytotoxic effects of DNR.

CONCLUSIONThe increased XIAP protein level contributes to the drug resistance induced by adhesion to Fn. AS-ODNs of XIAP might reverse the drug resistance.

This study was purposed to explore the mechanisms of drug resistance of HL-60/ADR cells and to compare the reversal drug-resistance effects of antisense oligonucleotides (AS ODN) of XIAP (X-linked inhibitor of apoptosis protein) and AS ODNs of MRP (multidrug resistance-associated protein) by use alone or in combination. Reverse transcription-PCR and Western blot were applied to detect the expression of XIAP, BCL-2, MRP and MDR1 in mRNA and protein levels of HL-60 cells and HL-60/ADR cells, respectively. Fully phosphorothioated AS ODN of XIAP and MRP was delivered into HL-60/ADR cells with Lipofectamine 2000 in the form of liposome-ODN complexes alone or in combination. CCK-8 cell viability assay was used to determine the effect of AS ODN of XIAP and MRP used alone or in combination on the chemotherapy sensitivity of HL-60/ADR cells to daunorubicin (DNR). Reverse transcription-PCR and Western blot were applied to examine the changes of XIAP, MRP in mRNA and protein levels respectively. The results showed that MRP and XIAP were both significantly higher in HL-60/ADR cells than those in HL-60 cells. AS ODN of XIAP and MRP down-regulated the expression of XIAP and MRP in HL-60/ADR cells and increased the sensitivity of HL-60/ADR cells to DNR, respectively. AS ODN of XIAP + MRP did not enhance the inhibition expression of XIAP in HL-60/ADR cells but increased the sensitivity of HL-60/ADR cells to DNR significantly as compared with AS ODN of XIAP (P < 0.05). AS ODN of XIAP + MRP did not increase the concentration of DNR nor enhanced the inhibition expression of MRP in HL-60/ADR cells but increased the sensitivity of HL-60/ADR cells to DNR significantly (P < 0.05), as compared with AS ODN of MRP. It is concluded that both XIAP and MRP may be involved in the drug resistance mechanisms of HL-60/ADR cells. Drug-resistance of HL-60/ADR cells can be reversed significantly when antisense oligonucleotides of XIAP and MRP were used in combination.

AIMTo discuss the merits of "tubes treatment" for esophageal fistula (EF).

METHODSA 66-year-old female who suffered from a bronchoesophageal and esophagothoratic fistula underwent a successful "three tubes treatment" (close chest drainage, negative pressure suction at the leak, and nasojejunal feeding tube), combination of antibiotics, antacid drugs and nutritional support. Another 55-year-old male patient developed an esophagopleural fistula (EPF) after esophageal carcinoma operation. He too was treated conservatively with the three tubes strategy as mentioned above towards a favorable outcome.

RESULTSThe two patients recovered with the tubes treatment, felt well and became able to eat and drink, presenting no complaint.

CONCLUSIONTubes treatment is an effective basic way for EF. It may be an alternative treatment option.

Objective To investigate the therapeutic effect of surgical management on patients with secondary epilepsy under the monitoring of cortical electrocorticography (ECoG). Methods Eighty-four patients with secondary epilepsy, admitted to our hospital from September 2004 to January 2008, were chosen; intraoperative ECoG monitoring was performed to locate the epileptic foci before the resection of the primary lesion. After the resection of primary lesion, resection of epileptic foci, enlarged resection of epileptic foci, cortical thermocoagulation, anterior temporal lobectomy,amygdalohippocampectomy and anterior callosotomy were performed, respectively, in different patients according to the clinical manifestations of seizures, and the locations of lesions and epileptic waveform discharges detected by intraoperative ECoG monitoring. Results The epileptic waveform discharges in 84 patients were noted before the resection of primary lesion. The epileptic waves were found in 80patients at the peripheral areas of the primary nidus under immediately postoperative ECoG monitoring,with a relevance ratio reaching 95.24%; after the resection of residual cortical zone with epileptic wave discharges, epileptic wave disappeared on immediately postoperative ECoG in 13 patients whose lesion located in nonfunctional area; normal signals were noted in 60 of the 67 patients performed cortical thermocoagulation whose cortical zone with epileptic wave discharges were located or neighbored in functional area, and good outcomes under the immediately postoperative ECoG monitoring were noted in the other 7 patients performed thermocoagulation combined with anterior callosotomy and/or amygdalohippocampectomy. The follow-up studies for 10 months to 4 years showed that grade Ⅰ in 56patients (66.67%), grade Ⅱ in 21 (25.00%), grade Ⅲ in 4 (4.76%) and grade Ⅳ in 3 (3.57%) according to the Engle standard of curative effect were achieved; the total effective rate was 96. 42%. Conclusion ECoG monitoring can significantly improve the efficiency of surgical management of secondary epilepsy.
