Objective To investigate the incidence and the related factors of the depression in Parkinson's disease. Methods 52 cases with idiopathic Parkinson's disease were included in this study. Such scales as Hamilton depression scale-24 item (HAMD-24), Non Motor Symptoms Scale for Parkinson's disease (NMSS), 39-item Parkinson's Disease Questionnaire (PDQ-39), unified Parkinson's disease rating scale (UPDRS), revised Hoehn-Yahr rating scale (H-Y), revised Schwab and English daily life event scale (S-E), Minimum Mental State Examination (MMSE), etc. were applied and underwent Spearman correlation analysis. Results Thirty-six patients with Parkinson's disease (69.23%) met the criteria for depression. The spearman rank correlation analysis showed that MMSE (r=-0.294, P=0.036) and S-E (r=-0.506, P<0.001) had negative correlation with depression in Parkinson's disease, and the course of the disease (r=0.274, P=0.049), UPDRS (r=0.485, P<0.001), H-Y (r = 0.459, P = 0.001), NMSE (r = 0.729, P < 0.001) and PDQ-39 (r = 0.619, P < 0.001) had positive correlation with depression in Parkinson's disease. Conclusions The patients with Parkinson's disease had high incidence of depression. The depression in Parkinson's disease is associated with many factors and affected the quality of life of the patients.

The recombinant fusion protein staphylokinase-hirudin(rSFH) was purified from the high density-fermented engineered E.coli by means of ion-exchange chromatography (IEC) and gel filtration (GF). The purity of rSFH reached to more than 98% determined by RP-HPLC and SDS-PAGE, and the yield was up to 0.7g per liter of fermentation broth. The analysis of homologous dimmer of rSFH appeared during the purification and calculation of the surface hydrophobic area had been carried out by means of hydrophobic chromatography and MALD-TOF. The influence of sodium chloride and temperature on the behavior of rSFH reversible dimerization was analyzed by high performance sized- exclusive chromatography(HPSEC). It is concluded that the hydrophobic interaction played an important role in the reversible dimerization of rSFH.

OBJECTIVETo investigate the relationship between the resistance index (RI) of the renal artery and serum creatinine (Cr) level in patients early (within one month) after renal transplantation.

METHODSA total of 123 patients receiving renal transplantation underwent examinations by color Doppler ultrasound for measurement of the RI of the renal artery within one month after the operation. According to the results of RI measurement, the patients were divided into RI≥0.75 and RI<0.75 groups for analyzing the correlation between RI and serum Cr level measured at the same time points.

RESULTSThe RI and Cr levels in patients with RI≥0.75 showed a significant positive correlation (P<0.05), whereas they showed an inverse correlation in patients with RI<0.75 (P<0.05). The patients with RI≥0.75 had significantly lower RI of the renal artery and Cr level than those with RI≥0.75.

CONCLUSIONRI is significantly correlated to Cr, and may serve as an indicator for predicting renal graft function after transplantation.

OBJECTIVETo investigate the characteristics of microbial degradation of aniline by a stable bacterial consortium.

METHODSThe bacterial consortium was isolated from activated sludge treating chemical wastewater using aniline as the sole source of carbon and nitrogen by enrichment and isolation technique. The biomass was measured as optical density (OD) at 510 nm using a spectrophotometer. Aniline concentrations were determined by spectrophotometer. The intermediates of aniline degradation were identified by GC/MS method.

RESULTSThe bacterial consortium could grow at a range of aniline concentrations between 50 and 500 mg/L. The optimal pH and temperature for aniline degradation were determined to be 7.0 and 30, respectively. The presence of NH4NO3 as an additional nitrogen source (100-500 mg/L) had no adverse effect on bacterial growth and aniline degradation. The presence of heavy metal ions, such as Co2+, Zn2+, Ni2+, Mn2+ and Cu2+ had an inhibitory effect on aniline degradation.

CONCLUSIONSThe isolated bacterial consortium can degrade aniline up to 500 mg/L effectively and tolerate some heavy metal ions that commonly exist in chemical wastewater. It has a potential to be applied in the practical treatment of aniline-containing wastewater.

Objective To survey the arsenic content of drinking water in Jingzhou City, to provide basis for prevention and control of endemic arsenic disease. Methods According to historical data, the .arsenic content of water was detected in 357 villages from 6 counties of Jianglin, Songzi, Gongan, Shishou, Jianli, Honghushi in Jinzhou City in 2007 and 2008, The past have been found to have high arsenic water villages, villages known to have high concentration of arsenic were put into census. Villages not found to have high-arsenic wells were sampled 10 percent of the whole water resources at five directions of east, west, south, north and the center. Using sampling investigation, water arsenic was determined by half -quantitative fast reagent kit. All samples of water with arsenic exceeding the standard were re-determined using silver diethyl dithiocarbamate using silver diethyl dithiocarbamate colorimetric mothod. Survey on the disease was carried out in the villages with arsenic exeeeding the standard. Results All 6074 water samples was inspected. Arsenic in 210 samples outnumbered 0.05 mg/L, 51 natural villages were high arsenic areas;The maximum level of arsenic content in drinking water was 0.7 mg/L 3.2% (152/4784) of the wells no deeper that 30 meters and 4.9%(58/1184) between 30 to 100 m had arsenic exceeding the standard The water arsenic content was normal when the wells was deeper that 100 m. The abnormal percentages of water arsenic was related with the depth of wells with a significant difference(χ2 = 12.29,P < 0.01). Medical examination 84 064 residents in 51 villages having high arsenic water 31 neighboring villages was made, No Patients was found suffering from endemic arsenic poisoning. Conclusions High arsenic source has been found in Jingzhou City ,but no endemic arsenic poisoning patient in Jingzhou City. It is suggested that necessary preventive measures should be taken in high arsenic area, low-arsenic water should be spotted or high arsenic water improved. Moreover, wells should be drilled for more than 100 meters or more in depth.

Objective To discuss the clinical application and efficacy of digitization prototyping titanium meshes in the repairing of earthquake-induced skull defect. Methods The clinical data of 66patients with skull defect caused by earthquake were analyzed. These patients were divided into group A (treated with traditional handwork shaping titanium meshes, n=1S) and group B (treated with digitization prototyping titanium meshes, n=51). The efficacy and complications were compared.Results Compared to group A, group B had a shorter operation time, a shorter recovery time, a lower postoperative incidence rate of subcutaneous hematocele, hydrops and infection (P＜0.05). The digitization prototyping titanium meshes were significantly superior to handwork shaping titanium meshes (P＜0.05). And patients with skull defect repaired at early stage had a higher recovery rate of neurological function than those at advanced stage (P＜0.05). Conclusion Using digitization prototyping titanium meshes to repair the skull defect can enjoy anatomical reduction, shortened operation time, and fewer postoperative complications. In addition, an early repair in earthquake-induced skull defect can not onlydisburden patients' mind, but also prevent or even reverse secondary brain damage of skull defect,therefore, the patients' neurological function can be improved and their lives can be better.
