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 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.

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.

It is important to explore the fundamental medical concepts which can enhance the overall quality of medical students in the department of geriatrics during clinical practice. These funda-mental medical concepts include medical humanistic spirit,holistic medicine,health management and patient-physician communication. Specific measures include improving emotional communication of clini-cal interns in department of geriatrics with elderly patients,training student's thinking as a whole towards multiple system disease in the elderly,training students to assess and manage elderly patients from a vari-ety of perspectives and improving doctor-patient communication skills by routine clinical teaching and teaching ward round. All these concepts will help improve the working ability and medical ethics of clini-cal interns and enable them to adapt to the clinical work quickly. So they can become qualified doctors.
10.Diagnosis of neonatal infections
Clinical Medicine of China 2014;(z1):94-95,96
Objective To investiGate the value of procalcitonin( PCT ),C reactive protein( CRP ), white blood cell( WBC)and platelet in the diaGnosis of neonatal infection. Methods The clinical data of 57 cases with neonatal infection in the First Hospital of Hefei were retrospectively analyzed. Select 65 healthy neonates in the same period as control Group. Compared two Groups of serum PCT,CRP,WBC and platelet levels, and diaGnosed of sensitivity,specificity of neonatal infection. Results There were statistical siGnificant differences between infection Group and control Group interms of CRP,WBC and PCT in newborn health neonates ( P<0. 05),but except the platelet( P>0. 05). The sensitivity and specificity of PCT were 54. 4% and 92. 3%, of CRP were 43. 9% and 84. 6%,of WBC was 29. 8% and 90. 8%,and of PLT were 38. 6% and 69. 2%. Conclusion PCT,CRP,WBC are of diaGnostic siGnificance for early diaGnosis of neonatal infection,and PCT has hiGh sensitivity and specificity of diaGnosis of neonatal infectious diseases.
