ve To study the mutagenecity of volatile organic compounds (VOCs) emitted from decoration materials to experimental animals and human subjects so as to provide some technical basis for the management of safety and hygienic quality of indoor decoration materials. Methods The micronucleus test was carried out in mice exposed to the tested toxicants in an experimental cabinet, in which the tested VOCs were prepared at the various concentrations which were 5, 10, 20 and 40 times as high as the concentrations of VOCs in decorated rooms monitored on site respectively. The frequencies of micronucleus of peripheral blood lymphocytes were examined among waitress working in decorated indoor environment. Results The concentrations of formaldehyde, benzene, methylbenzene, ethyl acetate, butyl acetate in decorated rooms were significantly higher than those in un-decorated rooms and the related national standards within half a year after decoration. The frequencies of micronucleus of mice exposed to tested VOCs with concentration being 40 times as high as those in decorated rooms were significantly higher than those of negative control group at the 15 th day after exposure. There were no significant differences in frequencies of mi-cronucleus in peripheral blood lymphocytes between waitress working in decorated rooms and un-decorated rooms. Conclusion VOCs emitted from decoration materials were uneasily diffused in air-conditioned airtight environment. The higher concentrations of VOCs simulated based on their levels in decorated rooms revealed mutagenecity to ex-perimental animals.

Objective To compare the effects of ureteroscopic lithotripsy (URL), minimally invasive percutaneous nephrolithotomy ( MPCNL) , retroperitoneal laparoscopic ureterolithotomy ( RLU) and open ureterolithotomy (UL) for the treatment of complex upper ureteral calculi. Methods The data of 281 patients with complex upper ureteral calculi from January 2005 to January 2013 were retrospectively reviewed. 48 patients of them received treatment of URL, 113 patients received MPCNL, 67 patients received RLU and other 53 patients received UL. Results Success rates of treatment at the first time were:URL 62.5% (30/48), MPCNL 92.9%(105/113),RLU 100%(67/67) and UL 100%(53/53) . The mean blood losses during the operation were:URL (9.2 ± 1.4) mL,MPCNL (72.5 ± 5.8) mL,RLU (43.1 ± 8.5) mL and UL (100.5 ± 9.2) mL. The average operation time of URL group was shorter than three other groups, and the difference was statistically significant (P< 0.05) . The average hospital stay of URL group was also shorter than three other groups ( < 0.05) . The difference was not statistically significant in complications among four groups after operation ( >0.05) . Conclusion Clinical characteristics of patients and individual require ment should be considered comprehensively before an individual treatment choice is made for the treatment of complex upper ureteral calculi.

To investigate influence of butylphthalide injection on serum neuron specific enolase, C-reactive protein and fatty acid binding protein levels in patients with cerebral vasospasm following aneurysmal subarachnoid hemorrhage.Methods Ninety patients with cerebral vasospasm were admitted to The First Affiliated Hospital of Fujian Medical University, then the patients were divided into two groups: The control group (45 patients) was treated with nimodipine and triple-H therapy after surgery;in addition to nimodipine and triple-H therapy, butylphthalide injection was administered to the experimental group(45 patients).Transcranial doppler(TCD)was used for the evaluating cerebral artery blood flow velocity, and the serum neuron specific enolase(NSE), C-reactive protein(CRP) and fatty acid binding protein(FABP) levels in patients with cerebral vasospasm were measured. Results The experimental group improved significantly more than the control group, a significant decrease in cerebral blood flow velocity of the middle cerebral artery in the experimental group as measured by TCD (P<0.05).The serum levels of NSE, CRP and FABP in the patients in the experimental group decreased more significantly (P<0.05).And the incidence of cerebral infarction in experimental group was lower than that in control group (P<0.05).Conclusion The serum levels of NSE, CRP and FABP in the patients with cerebral vasospasm following aneurysmal subarachnoid hemorrhage could be significantly reduced by administration of butylphthalide injection, which also could improve cerebral blood supply.Therefore, administration of butylphthalide injection is an effective treatment for cerebral vasospasm.

OBJECTIVE To explore the expression of Maspin in invasive fungal rhinosinusitis (IFRS) and the value of Maspin in the diagnosis of IFRS. METHODS Forty two cases of fungal rhinosinusitis (FRS) were set as the experimental group, which included 12 cases of IFRS and 30 cases of noninvasive fungal rhino-sinusitis (NIFRS). At the same time, 30 cases of chronic rhino-sinusitis were set as control group. Immunohistochemistry (IHC) was used to detect the expression of Maspin. RESULTS Compared with the control group, the expression of Maspin in FRS group decreased statistically (t=-3.367, P<0.05). The IFRS group, compared with other two groups, had the lowest expression of Maspin (t=-3.390, P<0.05; t=-4.143, P<0.05). By using Maspin score of 5.70 as the cut-off point, the sensitivity and specificity for the diagnosis of IFRS was 91.7% and 88.3% respectively. CONCLUSION The expression of Maspin is very low in IFRS group. Down-regulation of Maspin expression may be a potential indicator for diagnosis of IFRS.

_ Objective_ To evaluate the efficacy of unilateral subtotal adrenalectomy in the treatment of bilateral adrenal solitary neoplasma causing Cushing's syndrome and to elaborate the therapeutic principle. Methods From 2007 to 2013, a total of ten patients were diagnosed with Cushing's syndrome caused by bilateral solitary adrenal neoplasma. We compared patients'clinical symptoms, hormone profiles, biochemical and metabolic parameters, and imaging data before and after the surgery. Five of them chose the optimal neoplasma based on the lateralization ratio of adrenal venous sampling result and the other 5 patients chose the optimal neoplasma based on the diameter of the mass reflected by the computed tomography result and were then operated. Results After the unilateral subtotal adrenalectomy,the24-hour urinary free cortisol decreased significantly(P<0.05)and the midnight serum cortisol level also significantly reduced(P<0. 01). Plasma adrenocorticotropic hormone level increased significantly(P<0. 01). Nine patients of them did not need contralateral adrenalectomy and one patient received contralateral adrelectomy because of the remnant of Cushingnoid symptoms. Conclusion Unilateral subtotal adrenalectomy is an effective and safe way to treat Cushing's syndrome caused by bilateral solitary neoplasma.
