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.

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.

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 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.

10 kinds of normal and immunodifi-cient mice were used and they were found to have different levels ofNK activity.The NK activity toHuman to Human,Human to Mouseand Mouse to Mouse hybridomacells was much lower thanthat to YAC-1 cells in all mice andthere were no significant differencesbetween the two kinds of human Bcell hybridomas in susceptibility toNK cells.The results showed thatNK cells had no obvious effects onxenografts of human B cell hybri-domas.

The red blood cell sorbitol levels of 23 healthy subjects and 66 diabetic patients were measured enzymatically. Results showed that erythrocyte sorbitol levels of both IDDM (17) and NIDDM (38) patients with poor control were significantly higher than that of the controls and positively correlated with the coincident plasma glucose concentration, 24-hour urinary glucose excretion and HbA1c. There was no significant difference between the red cell sorbitol concentration of NIDDM with normal blood glucose level and that of the normal group; moreover, red cell sorbitol levels did not sig-nificantly correlated with FBG in both groups. Although there was no significant difference between the FBG of poorly controlled IDDM and NIDDM groups, red blood cell sorbitol levels were significantly different in both groups. This suggested that red blood cell sorbitol level could be used as an indicator of diabetic control.

The present paper is an analysis of the pattern reversal visual evoked potentials (P-VEP) of macular disease (40 cases, 57 eyes), in contrast to normal persons (40 cases, 80 eyes) of similar age. The group consists of 9 different kinds of disease-central serous chorioretinopathy macular hemorrhage, macular dege-neration, etc. The authors analyzed the latency and amplitude of P-VEP in different macular disease with different course and central vision. The results showed that the latency of P-VEP in the group was relatively prolonged. In contrast to normal person P 100 was prolonged by 9.0, 26, 40 ms at 1?2′, 30′, 16′ visual angles respectively. The amplitude was obviously lowered, especially at the visual angle of 16′ and P-VEP extinguished in all the eases with visual acuity less than 0.1.The latency and the amp-litude were not related to the type and the course of the maeular disease, but were closely related to the central vision.

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.

OBJECTIVE:To enhancement lawconsciousness and ability of self-protect of pharmacist.METHODS:Analysed the problem which occured in their work from the point of view of law and bring forward some advice.RESULTS &CONCLUSION:Pharmacist should do their work strictly according to the code for avoidance law risk.
