Objective To establish a new method for the determination of chromium (Ⅵ) in printing and dyeing wastewater. Methods A combined technique was employed for the determination of chromium (Ⅵ) by flow injection on-line separation and preconcentration on a micro column packed with alumina(acidic form) and inductively coupled plasma-atomic emission spectrometry (ICP-AES).The effect of acidity,concentration of eluent and coexistence ion on separation and enrichment was detected.Results The detection limit was 0.72 ?g/L.The LOQ was 2.38 ?g/L.RSDs were 1.45%~2.12%.The recovery rates were 96.0%-104.0%.The concentration enhancement of chromium (Ⅵ) was 10 times for 45 s sample loading.Analytic frequency was 33 samples one hour. Conclusion This method is sensitive,rapid and applicable to the determination of chromium (Ⅵ) in dyeing wastewater.

Objective:To investigate the eating disorder and mood among students of a female university in Beijing.Methods:352 female students from a same-sex college in Beijing,between the age of 17-25 years were in- vestigated by Eating Disorder Inventory(EDI)and Profile of Mood States-Short Form(POMS-SF).Their weight and height were also collected for calculating for their body mass index(BMI).Results:Female university students showed serious tendency of eating disorder.The negative attitudes to body and body satisfaction were serious among normal BMI female university students.The behaviors and attitudes to eating disorders among the students of fresh-woman and senior were significantly higher than other grades(x~2=17.94,P

Objective To systematically review findings on the effectiveness and safety of transcranial magnetic stimulation (TMS) for treating Parkinson's disease. Methods Foreign and Chinese databases were searched to find relevant trials. The searches were supplemented by searching the reference lists of the published trials. The studies were separated into two groups: those applying TMS at frequencies higher than 1 Hz, and those at 1 Hz or lower. Meta-analysis was performed with the aid of RevMan 5.0 software. Results Both low-frequency and highfrequency TMS can significantly reduce total scores on the Unified Parkinson's Disease Rating Scale (UPDRS) compared with sham stimulations. High-frequency TMS can significantly reduce UPDRS motor scores compared with sham stimulations. On the other hand, low-frequency TMS studies showed no significant overall improvement in motor scores, mental scores or in the activities of daily living (ADL) UPDRS scores. Low-frequency and high-frequency TMS studies also showed no significant overall improvement in Schwab and England ADL scores. Conclusions TMS therapy is safe and partially effective for treating Parkinson's disease.

Objective To investigate the similarity and difference in chronic obstructive pulmonary disease ( COPD) evaluation and drug selection that were compared between global initiative for chronic ob-structive lung disease (GOLD) 2011 and GOLD 2006, and to explore treatment adherence by doctors ac-cording to GOLD 2011.M ethods We collected 224 patients with COPD from Department of Respiratory Medicine at the Second Xiangya Hospital to investigate the differences in COPD evaluation and drug selec-tion according to GOLD 2011 and GOLD 2006 with treatment adherence by doctors according to GOLD 2011.Results ⑴According to GOLD 2006, there were 38 patients in the most severe stage, which was different from that (Group D, 147) according to GOLD 2011 ( P <0.01).⑵The risk stratification by u-sing pulmonary function assessment was significantly different from that by using exacerbation history.⑶Symptom assessment by using COPD assessment test ( CAT) was significantly different from that by using modified British medical research council ( mMRC) .The kappa coefficient of these two questionnaires was 0.466, suggesting moderate agreement.⑷ According to GOLD 2011, 224 (100%) patients were recom-mended to use inhaled long-acting bronchodilators, which was higher than that (213, 95.18%) according to GOLD2006 ( P <0.01).⑸The level of appropriated actual prescription was 161 (71.9%) according to GOLD 2011, which was significantly different from that (120,53.1%) according to GOLD 2006 ( P <0.01).Conclusions ⑴ Compared to GOLD 2006, GOLD 2011 categorized more patients into the most severe group.⑵The risk stratification of COPD by airflow limitation severity or exacerbation risk was not i-dentical.Discordance between CAT and mMRC was observed.⑶GOLD 2011 recommends a wider range of using long-acting bronchodilators.⑷The adherence to GOLD guideline in our hospital is still far from satis-faction.

Objective To analyze the inducement,clinical manifestations,diagnosis and treatment of diabetes patients with multiple organ failure(MOF).Methods A retrospective analysis of 64 diabetes patients with multiple organ failure was executed,the clinical data were statistically analyzed.Results Heart failure was the most common in 64 cases with a incidence of 100.0%,the rest common failure organ were kidney(92.2% ),brain( 32.8% ),lung ( 14.1% ),gastrointestinal tract (3.1% ),and liver( 1.6% ).Cases with the glucose level over 33.5mmol/L illustrated a significantly higher incidence than other groups ( P < 0.05 ),glucose level between 22.5 and 33.4mmol/L group was significantly higher than the 12.2 ~ 22.4mmol/L group( P < 0.05 ) The inducement of MOF were infection (76.6% ) medication terminate ( 9.4% ),ketoacidosis ( 7.8% ),cardiovascular and cerebrovascular accidents (6.3% ).Conclusion Positive control of blood glucose in the early stage of diabetes,prevent complications,eliminate the incentive could reduce the incidence of MOF,eventually reduce the mortality rate.
