Objective To evaluate the effect of breast-feeding on newborns' pain caused by heel prick. Methods A convenient sample of sixty newborns from a hospital in Beijing undergoing heel prick for the Newborn Screening Program Blood Test were enrolled. They were randomly divided into breast-feeding group and control group. The newborns in the breast-feeding group began to receive breast-feeding at two minutes before the heel prick until 8 minutes after the heel prick finished. The newborns' grimace,cry,heart rate (HR) and oxygen saturation (SaO_2) were recorded and compared between the two groups. Results There were significant differences on the starting time and lasting time of grimace and cry caused by pain,numbers of crying neonates,SaO_2 during and 1 to 4 minutes after heel stick,as well as the recovery time of SaO_2 after heel stick between the two groups (P＜0.05 or P<0.01). Conclusion Breast-feeding can relieve newborns' pain caused by heel prick.

A model for measuring the impact of Chinese papers published by hospitals in China was established, followed by an analysis of the contribution of the total citations, the number of fund-supported papers, the number of papers published in core journals, the number of papers published in core journals of Chinese Medical Associa-tion to the impact of papers, which showed that these parameters could effectively measure the impact of Chinese papers published by class A hospitals in China.

Quality assurance(QA) and Quality Control(QC) of MRI has become very realistic and imperative,which can ensure safety and availability of MRI and improve diagnosis quality.From the practice of the daily grind of MR,the connotation and main content of MR QA and QC are discussed.It is illuminated that MR QA and QC not only should be standardized and systemized,but also needs leaders' recognition and everyone's participation.The responsibility of medical engineers includes emergency maintenance,preventive maintenance,optimization of sequences and parameters,development and application of new techniques Clinical engineers play an irreplaceable and important role in the whole process of MR QA/QC.

The effect and value that are assurance of standard operation in quality control and administration of digital im- ages were discussed. The putting forward concept and aim of standard operation were classified into four grades: best, good, checkout and below standard according to evaluating factors and conditions of standard operation. In order to guarantee the implementation of quality control, medical staff should renew ideas and enhance the consciousness of quality control. The standard operation can be guided and supervised by the director in machine and the system of rewards and penalties can be established. The standard operation has important significance and values, which carry out quality control and quality ad- ministration in medical imaging effectively.

Objective: To investigate the role of clinical pharmacist in anticoagulant therapy.Methods: Clinical pharmacist participated in the anticoagulant treatment adjustment for one patient with deep vein thrombosis (DVT) of lower limbs.Clinical pharmacist assessed the risk factors of DVT and the bleeding risk of anticoagulant therapy, provided suggestions in case of over-anticoagulation with warfarin, and offered medication education to the patient with unsatisfactory compliance.Results: Physician adopted the suggestions of clinical pharmacist, INR was within the rational range, and the patient was discharged with stable condition.Conclusion: The participation of clinical pharmacist in the anticoagulation with warfarin can reduce the risks of drug use and promote the efficacy and safety of medication effectively.

s Objective To explore the value of B mode ultrasound in the detection of amniotic fluid(AF) for fetus of 41～ 46 +6 gestation weeks.Methods B mode ultrasound was performed to monitor AF in 232 fetus of 41～46 +6 gestation weeks compared with that in 296 fetus of 37～40 +6 gestation weeks. Results There were significant differences in amniotic fluid index(AFI), amniotic fluid muddy(AFM) and cavity fetal distress(CFD) between the two groups (P

To optimize bacteriocin production,researching was done on the respect of incubation condition and the media components. And the optimum incubation time was 24h, the optimum temperature was 30℃, the optimum broth initial pH was 6.5. The optimum media component was: lactose 30g, trypone 15g, soybean peptone 20g, meat extract 30g, peptonethe 20g, Tween 80 1mL, K_(2)HPO_(4 )2g, NaAc 5g, Tri-Ammonium citrate 2g, (MgSO_(4)) 0.58g, MnSO_(4) 0.25g, H_(2)O 1000mL. Production of bactericoin under the optimum broth was 640AU/mL, 8 times than MRS media.

Objective: To understand the effect of abnormal thyroid function on body composition. Methods: Selected course was less than 5 years with thyroid dysfunction disease, after the doctor's standard advice for medicine and good clinical symptom control, 185 patients with hyperthyroidism (male 72, female 113), 154 patients with hypothro idism (33 male, 121 female) and healthy control group 344 cases (male 92, female 252) were included, the application of biological resistance was used respectively measuring body composition, analysis of limbs, trunk and body fat, the differences between the content of skeletal muscle. Results: In men, the muscle mass in the hyperthyroidism group was significantly lower than that in the control group (P<0. 01). There was no significant difference in muscle mass in other groups, and no significant difference in fat mass between the three groups. In women, the muscle mass in all parts except the lower limbs in the hypothroidism group was significantly higher than that in the hyperthyroidism group and the control group (P<0. 05), while there was no significant difference in muscle mass between the hyperthyroidism group and the control group. The fat content of all parts except the lower limbs in the hypothyroidism group was significantly higher than that of the healthy control group and the hyperthyroidism group (P<0. 05), while there was no significant difference in the fat content of all parts between the healthy control group and the hyperthyroidism group. Conclusion: Hyperthyroidism can lead to decrease muscle mass in the trunk of male patients. Hypothyroidism can increase the amount of muscle and fat in the body composition of female patients.

Objective: To improve the database of medical equipment archives system and manage medical equipment more scientifically and efficiently. Methods:According to the needs of medical equipment management, the problems of medical equipment archives system would be analyzed and addressed. Results:In recent medical equipment archives system, the database of usage rate, cost-effectiveness, maintenance costs and property management should be improved. Conclusion:The improved archives system could provide reliable basic data and multi-faceted sharing for medical equipment dynamic management.
