Objective To compare the sensitivity of body mass index (BMI),waist-hip ratio (WHR)and percentage body fat (PBF)in the evaluation of the obese adolescents population,and find a more sensitive evaluation method.Methods In this study,2 045 adolescents were recruited in the city of Chongqing by using multiple-stage random cluster sampling,and they were identified as overweight or obesity on the base of BMI,WHR and PBF.Results There was significant difference among the detection rate of the three methods (P<0.05),the detection rate of PBF was the highest (12.9%),then BMI (7.2%)and WHR (6.0%).consistency test showed that the concordance of three methods was poor and Kappa (BMI and WHR)=0.199,Kappa (BMI and PBF )=0.441,Kappa (WHR and PBF)=0.187;comprehensive evaluation was chosen as the gold standard and compared with three meth-ods respectively by ROC curve,the analysis showed that area under curve (AVC):PBF(0.954)>BMI(0.918)>WHR (0.694). Conclusion The sensitivity of PBF and BMI was higher.Although the WHR sensitivity was lower,WHR is a good predictor asso-ciated for chronic diseases,which suggests that the development of appropriate adolescent WHR standard is necessary.

Objective: To investigate the effect of two modes of one-lung ventilation(OLV) on lung lobectomy in pediatric patients.Metheds: Twenty ASA Ⅰ-Ⅱ patients(8 male,12 female) aged 2~14 year,weighing 10~30 kg,and undergoing lung lobectomy were enrolled in this study.The patients were premedicated with intramuscular Sod Luminal 3~5 mg/kg and Atropine 0.01 mg/kg im,30 minutes before induction.Induction was performed with Dorcum 0.1 mg/kg,Fentanyl 5 ?g/kg and Vecuronium 0.1 mg/kg,maintained with Vecuronium 70 ?g/(kg?h) and Propofol 5mg/(kg?h) iv boluses.Ordinary tracheal tube was inserted into bronchus(14right,6 left) during OLV.First,OLV with volume-control mode maintained 25 min,and then,OLV with pressure-control mode was performed.In first step Vt was set at 8~10 ml/kg and respiratory rate was adjusted to maintain PetCO2 between 30~40 mmHg.In second step the inspiratory pressure was set according to the plateau pressure during step 1,hemodynamics and PaO2 were measured and recorded.Results : During OLV with pressure-control mode PaO2 was significantly increased,as compared with that during volume-control mode(P

Objective: To study the expression of Echinococcus multilocularis 14-3-3 antigen encoding gene in Bacillus Calmette-Guerin(BCG).Methods: The recombinant plasmid pBCG-Em14-3-3 was introduced into BCG by electroporation and the bacteria with pBCG-Em14-3-3 were cultured to logarithm growth period,then induced daily by heating at 45℃ for 30min in the last three days.The expression products were analyzed by SDS-PAGE and Western blot.Results: The Em14-3-3 recombinant protein was successfully expressed by pBCG-Em14-3-3 in BCG as an obvious band of 27kDa by SDS-PAGE,which accounted for 11% of total bacterial protein in BCG.Conclusion: The pBCG-Em14-3-3 could be expressed efficiently in BCG and be combined with specific antibody in mice sera,which suggested that the Em14-3-3 recombinant protein expressed by rBCG-Em14-3-3 vaccine was of specific antigenicity.

Objective To observe the auto-limbal epithelium and amniotic membrance transplantation in treatment of Symblepharon.Methods Transplant with auto-limbal epithelium and aminiotie membrance including 23 patients (31eyes) some of them are recurrentcd pterygium,most of them are symblepharons.[ Result ] In the followup period for 3～12 months,Ocular surface reconstruction was successful in 26 of 31 eyes with symb|epharon,but five of them recurrented three months later with lees than pre-transplantation in degree.Conclusion The transplantation with auto-limbal epithelium and membrance transplantation is an effective method for the symblepharon.

This paper introduces primarily the design of hardware and software systems in infrared automatic handwash basin including the working process of the electric circuit. At the same time, in order not to act mistakenly suffering from exterior interference, the anti-interference function is added to the software, which is also the design technique of this software.

Artificial hip replacement is an effective therapy to eliminate hip pain,correct deformity and restore function.With population aging and improving of people life quality,artificial hip replacement has been widely conducted.Over the past 40 years,artificial hip replacement technique has rapidly developed,and minimally invasive technology presents development direction of future artificial hip replacement.Skilled operation experience and instrument application are two key factors to ensure surgery success.The minimally invasive technology arouses more attention from clinical doctors and patients due to minimal invasion,little blood loss and fast recovery.However,not all patients can undergo minimally invasive hip replacement.This paper summarized related studies on minimally invasive hip replacement in domestic,and discussed the indications,surgical approach,complications and prevention.

This paper briefly analyzes the main factors influencing the quality of the undergraduate thesis and points out that the guarantee of improving the quality is to strengthen the management of undergraduate thesis,improve overall capacity of teachers and train general capability and good attitude of students,etc.

This paper describes the design of the peer education program for middle school students’ prevention of tuberculosis. It includes program implementation plan,selection and training of peer educators,format,content and evaluation of peer education,etc,all of which were used for quality assurance of peer education.

This paper introduces general guidelines for designing and constructing a magnetic stimulator (MS). These guidelines cover the theoretical concepts, hardware aspects and necessary components. RLC model producing the impulses in MS is focused on and the way to calculate the parameters of the model is presented. Some factors that influence induced magnetic field are discussed. Experiments are carried through with self-developed round coil and 8-shaped, and Tesla meter is used to detect the magnetic fields. The experiments data show that the distribution of the induced magnetic fields by the two coils are tailored to those of theoretical calculation adopted now. A simulation experiment to measure magnetic field in brain has been completed.

OBJECTIVE: To enhance the quality of pharmaceutical care of licensed pharmacists in medical services, and to ensure safe, effective, economical, and rational use of drugs. METHODS: The status quo and the problems existing in the legal guarantee of licensed pharmacists in medical service were analyzed, and the necessity of reinforcing legal guarantee for licensed pharmacists in medical service and the feasible measures were discussed. RESULTS & CONCLUSIONS: It is urgent to set and enforce "Licensed Pharmacist Law" to safeguard the legal rights of licensed pharmacists in medical service in the mo-de of law, facilitate the implementation of licensed pharmacist system in medical service, consummate management on licensed pharmacists, reinforce licensed pharmacists' consciousness of legal guarantee, and enhance the quality of pharmaceutical care.
