Tetrabromobisphenol-A (TBBP-A) is the most widely used brominated flame retardant in the world. It is a kind of potential environmental endocrine disruptor, similar to the persistent organic pollutants. It can accumulate in the environment and biota and it has adverse effects on the environment and the living creature, such as disrupting the action of hormones related to the skeleton and brain development. Research progresses on TBBP-A, including toxicology, analysis methods, were reviewed in this paper.

Objective To assess the conscious sedative effect of midazolam during the procedure of ERCP, in terms of general stress responses of the patients, the circulatory change, tolerance, patient cooperation and safety during and after the procedure. Method One hundred twenty patients undergoing standard ERCP using the same model of endoscope. Each patient received intramuscular injection of midazolam at 0. 15mg/kg 20 min before starting the procedures. The sedative score (OAA/S) and the major vital signs (mean arterial pressure( MAP) ,heart rate(HR) and atrerial oxygen saturation (SpO2) ) were recorded during and after the endoscopic procedure. The degree of amnesia of the patients and the extent of satisfaction on both patient and physician sides were also assessed. Results The procedures were successfully completed in all patients. There was no significant change in MAP,HR and SpO2 in these patients. The adverse reactions to the procedures were significantly reduced. No signs of respiratory suppression was observed among this group of patients during and in the immediate post procedure period. Conclusion Conscious sedation by intramuscular injection of midazolam at a dose of 0. 15mg/kg 20min before the ERCP ameliorates the stress of the patients , maintained and steady hemodynamic condition for the procedure and an amnesia status after the procedure. Hence, midazolam is a satisfactory consions selative agent applicable in the ERCP examination.

Objective To evaluate the effect of fast track surgery on immunologic functions and clinical outcome in patients with gastric cancer during perioperative period. Methods Thirty-six gastric cancer patients receving radical operation were randomly divided into two groups: fast track group (18, fast track surgery) and conventional management group (18, non-fast track surgery). Serum levels of IgA、IgM、 IgG and C reaction protein (CRP) in 36 patients were assayed preoperatively and postoperatively on 1st, 3rd, 7th day. The postoperative hospital stay, duration of fever, inhospital expense, postoperative time of flatus and postoperative complications were recorded respectively. Results On the postoperative 3rd day, serum levels of IgA [(1.57 ± 0. 40) g/L vs. (1.27±0.49) g/L, P <0. 05],IgG[(9.99 ± 2. 12) g/L vs.(8.53±2. 15)g/L, P<0.05]and IgM [(0.92 ± 0.18) g/Lvs. (0.78 ± 0.20) g/L, P<0.05]in patients of fast track group were significantly higher than those in patients in non-fast track group. On the postoperative 1 st, 3rd , 7th day, serum levels of CRP [d1 (56 ± 10) g/L vs. (79 ± 9) g/L,P < 0. 05];d3[(140±15) g/L vs. (170±15) g/L, P<0.05)];d7 [(52±11) g/L vs. (78±12) g/L,P<0.05]in patients of fast track group were significantly lower than those in patients in non-fast track group. The duration of fever [(2. 4 ± 0.9) d vs. (3.8 ± 0. 8) d, P < 0.05], passage of gas by anus [(3. 1 ± 0. 8) d vs. (4.4±0.7) d,P<0.05], time of hospitai stay [(6.3 ± 1.2) d vs. (8.2 ± 0.9) d,P<0.05]and treatment expense in patients of fast track group[(25 260 ± 2910) $ vs. (30 651 ± 3578) $ ,P <0. 05]were also significantly lower than those in non-fast track group (P < 0. 05). Patients in fast track group had no more complications than those in non-fast track group (P > 0. 05). While discharged from hospital, the quality of life score [(14. 8 ± 1.9) vs. (16. 1 ± 1.6), P < 0. 05]in patients of fast track group was significantly higher than that in patients in non-fast track group (P < 0. 05). Conclusions Fast track surgery mitigates the immunologic impairment of gastric cancer patients during perioperative period, and accelerates postoperative rehabilitation.

Objective To investigate the inheritance principle of the expanded GAG repeat allele and the clinical features of spinocerebellar ataxias 3 (SCA3) in a consanguinity family with first cousin marriage.Methods The CAG repeats of SCA3 gene were amplified by means of polymerase chain reaction.Fragment analysis with laser-induced fluorescence in capillary electrophoresis were performed for the positive samples detected by agarose gel electrophoresis.Furthermore,the clinical features were analyzed carefully.Results Fragment analysis revealed that the proband carried 2 alleles with 56 and 72 CAG repeats separately.The proband' s father carried 28 and 66,and the expanded CAG repeat allele inherited from his grandfather.The proband' s mother carried 33 and 56,and the expanded CAG repeat allele inherited from his grandmother.The proband' s son carried 27 and 85 and presented with dystonia besides ataxia.Conclusions The proband' s parents have the common ancestors.Their alleles with expanded CAG repeats probably come from the same allele of their ancestor.The GAG repeat is more unstable in the paternal inheritance than in the maternal inheritance.The 71-year-old asymptomatic family member carry the allele with 56 CAG repeats,which indicates the 56 CAG repeats may be not associated with the disease.The patients within this family have variable clinical features,especially the juvenile-onset case presents with apparent dystonia.

Objective To investigate the clinicopathological features of renal cell carcinoma (RCC).Methods From December 1956 to August 2012,the clinicopathological features of RCC were studied in 705 cases and related literatures were reviewed.Results The diameter of RCC ranged from 0.6 to 18.0 cm,which the average size was 4.6 cm.The proportions of the clear cell,papillary,multilocular clear cell,chromophobe and unclassified histologic subtype were 88.9％ (627/705),4.1％ (29/705),3.3％ (23/705),1.3％ (9/705) and 2.4％ (17/705),respectively.According to the Fuhrman grading system,the proportions of grade 1,2,3,4 were 19.0％ (116/612),58.3％ (357/612),18.1％ (111/612)and 4.6％ (28/612),respectively.The rates of invasion into the renal pelvis,perirenal fat and vascular were 10.9％ (66/603),10.6％ (64/603) and 4.8％ (29/603),respectively.Of 705 cases,464 (76.6％)cases were in T1,65 (10.7％) cases in T2,73 (12.0％) cases in T3,and 4 (0.7％) cases in T4.As to the lymph node and distant metastasis,the rate was 2.8％ (17/606) and 3.5％ (21/606).The percentages of stage Ⅰ,Ⅱ,Ⅲ and Ⅳ RCC were 74.3％ (450/606),9.9％ (60/606),11.7％ (71/606) and 4.1％(25/606),respectively.The 3-,5-,10-and 15-year disease-specific survival rate for RCC was 92.8％,86.9％,76.8％ and 55.5％,respectively.To those patients with clear cell RCC,the disease-specific survival at the same time point was 92.8％,88.1％,77.4％ and 55.4％,respectively.Multivariate analysis showed that the stage was the only independent prognostic factor for RCC.Conclusions Tumor stage of RCC is the independent prognostic factor for disease-specific survival.The evaluation of renal sinus invasion and lymph node should be noted in the diagnosis of RCC.
