Objective:To study the antibacterial activity of dental amalgam against S.mutans in vivo.Methods:Plaque samples were collected from amalgam surface 1 d,1,2,4 and 8 weeks after tooth restoration with amalgam( group of fresh amalgam) in 16 subjects and from anothor 14 subjects with amalgam tooth restoration for more than 3 years (group of aged amalgam).Plaque samples were collected only once.Isolation frequency (IF) and colony forming unite(CFU) of S.mutans were tested.The plague samples from oposite tooth were used as the controls.Results:In the group of fresh amalgam IF and CFU of S.mutans were heigher on amalgam than on the control teeth(P0.05).Conclusion:Amalgams may have inhibitory effects on the growth of S.mutans.

Training of doctor receiving in-service training is the important part of clinical education in teaching hospital. It will improve the clinical and scientific research ability of the doctor receiving in-service training and will train high-quality medical persons for primary hospital by training before going to post,clinical teaching,surgical operation teaching,standardized special lecture,case report and various kinds of science activities.

20 mm),these three imaging techniques(HAP-MDCT,Lipiodol CT and DSA)had the same sensitivity,for 10~20 mm hepatic nodules,the detecting rate was no significant difference among them,while,for

Objective:To compare the healing of gingiva after electrosurgical gingivectomy with different power outputs and electrodes. Methods:15 rabbits were randomly assigned to 3 groups which used different electrodes: needle electrode, long loop electrode and loop electrode. 1 animal was chosen as control in each group. Free gingiva of anterior teeth had been removed 2 mm in height with different power output and electrosurgical knife. Gingival specimens were harvested for histopathological study on days 1,7,14,and 21 after operation. Statistical analysis was performed on wound healing. Results:Electrical knife with medium power output caused significantly higher degree of inflammation than other techniques(P0.05). Conclusion:When electrosurgery is used on gingiva, there is no significantly difference with different electrodes. Longer observation is needed after gingival electrosurgery with medium power output electrical knife.

Objective:To investigate effects of strengthening the spleen and tonifying the kidney and their combination before and after exercise on relative indexes of metabolism of glucose and amino acids.Methods:Strengthening the spleen alone,tonifying the kidney alone or their combination before and after exercise was given to the rat receiving 7-week gradually increasing load exercise on a running platform,and after quantitative load,contents of serum lactic acid,urea nitrogen,glucose,hepatic glycogen,muscle glycogen,hemoglobin,and malondialdehyde(MDA)in renal tissue and activity of superoxide dismulase(SOD)in the renal tissue were determined.Results:Strengthening the spleen before exercise increased hepatic and muscle glycogen contents,and tonifying the kidney before exercise increased muscle glycogen content,and strengthening the spleen combined with tonifying the kidney before and after exercise increased hemoglobin level,strengthening the spleen followed by tonifying the kidney before exercise decreased serum lactic acid and urea nitrogen levels,increased muscle glycogen content and SOD activity/MDA content ratio in the kidney.Conclusion:Strengthening the spleen and tonifying the kidney play a certain role in reducing motion-related fatigue,while strengthening the spleen followed by tonifying the kidney before exercise has the best results.

Recombinant antibodies have become the major growth trends in biotech industry following their success on therapeutic application and good revenue. But the low level of mammalian expression and laggard fermentation process constrained the development of antibody industry in China. The global advances of antibody industry were reviewed, compared the respective advantage between dihydrofolate reductase and glutamine synthetase expression system, continuous perfusion and fed-batch processes were compared. Finally, based on the knowledge and experience of antibody expression and fermentation, the suitable strategy of antibody industrialization, e.g. the fermentation model and scale, should depend on the comprehensive consideration of entrepreneur for the productivity, manufacturing capacity and market revenue. It may be a wise choice to use glutamine synthetase expression system and continuous perfusion process for the need of Chinese antibody industrialization.

Objective: For information collection and processing problems currently existing hospital medical equipment management, we design a system design scheme based on RFID technology to achieve the implementation of intelligent management and data processing. Methods:RFID technology is through the electronic tag, reader, the application software system to accomplish the working process of the RFID system. Results:System design scheme can realize comprehensive monitoring and management of hospital medical equipment;realize information management of hospital equipment. Conclusion:The advantage and the use value of RFID technology will change management mode of medical equipment, and bring new opportunities and challenges to the medical equipment management.

Grant administration in hospitals is one of the important tasks for administrators of scientific research, and all leaders should also pay enough attention to it and regard it as a strategic assignment of hospital development. In this paper, we found out the key points in different phases of scientific researches through quality analysis of grants and the whole procedure of research, and put forward the keystone administration. We also discussed a new model of subject construction, thesis and achievements administration leaded by grant administration, which should basically and greatly raise the level of scientific research in the hospital.

Objective To evaluate the efficacy of servo controlled sevoflurane closed-circuit anesthesia and the feasibility of the predictive and intelligent control.Methods One hundred and forty-three ASA Ⅰ-Ⅲ patients (90 males, 53 females) aged between 3-77 yrs undergoing elective surgery were studied. Anesthesia was induced with intravenous fentanyl 2-3 ?g ?kg-1 , midazolam 0.12 mg?kg-1 and vecuronium 0.1 mg?kg-1 . After tracheal intubation the tracheal tube was connected to the servo-controlled closed-circuit system composed of IBM computer, O2 mass flow controller and electrically controlled sevoflurane injection pump and multifunctional monitor. The fresh gas flow of O2 = [body weight (kg)3/4 ? 10 + 20] ml?min-1 . The end-expired sevoflurane concentration was maintained at 1.3 MAC by predictive and intelligent control.Results The average wash-in time to reach the target concentration was (5.2 ?2.4) min. The O2 flow rate was(0.22?0.04) L?min-1 . The cumulative uptake of sevoflurane was 5.16 ml, 7.74ml, 9.17ml, 11.08ml, 12.57ml, 13.00ml, 14.18ml, 15.60ml, 18.56ml and 24.6 ml at 30, 60, 90, 120, 150, 180, 210, 240, 300 and 420 min respectively. The uptake rate of fluid sevoflurane was equivalent to (0.2673e-0.0598t + 0.2269e-0.0597t + 0.1150e-0.002t) ml?min-1 . Conclusion The servo controlled sevoflurane closed-circuit system can effectively control the pre-set end-tidal sevoflurane concentration in spite of the influence of multiple factors and is safe and effective.
