ABSTRACT
This device is an auxiliary device with reasonable design for placebo acupuncture research, so as to make double-blind placebo acupuncture control possible. This new auxiliary acupuncture device includes an acupuncture device and a placebo acupuncture device with exactly the same appearance. Both of them are composed of a hemispherical base and a telescopic tube. Through the rotation of the telescopic tube in the notch of the base, the insertion angle of needles can be adjusted from 15 degrees to 165 degrees. The operation of twisting and lifting and inserting can be carried out through the horizontal rotation and vertical sliding of the telescopic tube. A silicone needle pad is arranged in the base, which can simulate the blocking feeling of skin and muscle during needle insertion. The bottom of the base is attached with hydrogel, which has good fixity. The auxiliary device is applicable to multiple parts of the human body and can effectively reduce the risk of unblinding.

ABSTRACT
Objective:To explore the application effect of risk management in quality control of medical apparatus and instruments of operation room.Methods: 172 pieces of medical apparatus and instruments were divided into risk management group (n=86) andcommon management group (n=86). A series of indicators, such as effective acceptance rate, qualified cleaning rate, completed supporting facility, specific aim rate, deficiency rate of quantity, error rate of preparation, wet pack rate of sterilization, lost rate of post surgery and the satisfaction degree of physician, were applied to complete statistic analysis.Results: The effective acceptance rate, qualified cleaning rate, completed supporting facility rate and specific aim rate of risk management group were significantly higher than that of common management group (x2=5.02,x2=7.38,x2=9.35,x2=11.14,P<0.05). The deficiency rate of quantity, error rate of preparation, wet pack rate of sterilization, lost rate post surgery of risk management group were significantly lower than that of common management group (x2=6.63,x2=9.21,x2=11.34,x2=13.28,P<0.05). And the satisfaction degree of physician of risk management group (97.7％, 84/86) was significantly higher than that of common group (73.3％, 63/86) (x2=12.83, P<0.05).Conclusion: The application effect of risk management is better than that of common management in the quality control of medical apparatus and instruments in operation room.

Conclusions Application of cleaning packaging of surgical medical apparatus and instruments in sterilization and supply center can effectively control the cleaning and packaging quality,guarantee the thoroughness of subsequent disinfection and sterilization,decrease the incidence rate of nosocomial infection caused by poor quality of surgical medical apparatus and instruments.It creates reliable medical environment for patients and obtain good social and economic benefit,which is worthy of wide application.
ABSTRACT
OBJECTIVE:To test the efficacy and safety of PhilVent, a pressure limited, time cycled, Philippine ventilator through animal and clinical studies. METHODS AND RESULTS: Animal study: Term, newborn piglets (N=8) were intubated and alternately cycled to the PhilVent or to a pressure limited, time cycled, commercial ventilator (Sechrist) at peak inspiratory pressures of 10, 13 and 15 cm H20 and rates of 15, 20, 25 breaths per min and constant FiO2 (0.40) and positive end expiratory pressure (+4). Blood gases and adverse events (pneumothorax, sudden deterioration, death) were monitored. Results show no significant difference in blood gases on either machine at the various ventilator settings. No adverse events occurred. Clinical study: Prospective, randomized, controlled trial of 90 preterm infants with respiratory distress, randomized either to PhilVent (N=45) or Sechrist (N=45). Ventilator settings were adjusted to achieve predetermined range of blood gases. Arterial blood gases and any adverse events e.g., pneumothorax, pulmonary hemorrhage were monitored. There were no clinically significant differences in the ventilator settings or blood gases of the infants on the PhilVent or Sechrist. No increase in adverse events were noted with the PhilVent. CONCLUSION: In animal and clinical studies, the efficacy and safety of the PhilVent were comparable to the Sechrist. The PhilVent is an effective, alternative ventilator for the treatment of respiratory insufficiency in newborn infants.

OBJECTIVE To attend to the importance and issues of using the enzyme cleaner for the reprocessing of medical instrument. METHODS The principle, usage, precautions, and the selection of enzyme cleaner were analyzed. RESULTS The cleaning of the medical instrument must use the liquid enzyme detergent that has the following characters: clear solution, no or low foam, free rinsing, flexibilities to the water temperature, and no limitation to the water quality. CONCLUSIONS For successful cleaning of the medical instrument the use of the high-quality enzyme cleaner is required. A complete cleaning of the medical instrument is the first step to assure the quality of disinfection, sterilization, and the infection control.

ABSTRACT
Objective To determine the value of vascular indication of sexual excitation response (VISER) in the diagnosis of erectile dysfunction (ED). Methods Fifty three cases of ED underwent PGE1 intracavernous injection,VISER and color duplex ultrasonography.The comparison of the results was performed. Results Forty three cases were in Porst Grade 3, whose average cavernous pressure and carvenous pressure index were 144.29 mmHg and 1.24,respectively.Of them,42 cases were of normal penile vascular function,the remaining one was of venous ED;10 cases were in Porst Grade 2, whose average cavernous pressure and carvenous pressure index were 87.76 mmHg and 0.81,respectively.There were significant differences in the average cavernous pressure and carvenous pressure index between the two groups ( P
ABSTRACT
Objective To evaluate VISER as a non invasive monitoring of penile cavernosal pressure for the diagnosis of ED. Methods With the use of AVSS and papaverine ICI,39 cases,including 32 patients of ED and 7 controls,were tested with VISER device. Results 7 controls and 13 ED cases (40%) have achieved a valid erection by AVSS alone while another 13 ED cases required papaverine ICI (10 mg) for successful erection whereas 6 of ED cases failed what so ever. The VISER testing showed the erection data and peak data indexes, especially in total energy of erection and peak, were higher in controls than ED groups except the average duration of erection being longer in ED papaverine group. Conclusions VISER is an accurate system for measuring the changes of intracavernosal pressure in dynamic state during penile tumescence. The use of eye glasses TV monitor can help enhance the effectiveness of AVSS and lower the dosage of vasoactive drugs.VISER testing is non invasive,accurate and easy to perform and might serve as a screening test for ED patients in the near future.
