Objective:To explore the organizational and operational models of collaborative construction of Research and Development (R&D) platforms by innovative hospitals and enterprises, aiming to provide support and a guarantee for accelerating scientific and technological innovation and the transformation of achievements.Methods:Taking the co-construction of a joint R&D platform by Beijing Tiantan Hospital with enterprise as a case study, this study discussed the necessity of platform construction, and from the perspective of management practices, focusing on analyzing construction models, operational management, achievement attribution, and profits distribution, as well as other critical issues in platform construction.Results:Hospitals and enterprises agreed on the cooperation and co-construction model by signing an agreement. The management committee system and the centre director responsibility system were important operation and management mechanisms. The intellectual property rights of the outcomes generated by the cooperative R&D based on the joint R&D platform were co-owned by the cooperative parties. Data security, close communication, and high-quality research output were the critical issues for the sustainable cooperation between hospitals and enterprises. At the same time, this article proposed optimized management measures to address existing problems in the cooperation of the hospital-enterprise joint R&D platform.Conclusions:The hospital-enterprise joint R&D platform, as a new model of innovative collaboration between hospitals and businesses, held significant importance for tackling ″bottleneck″ technologies in medical science, the implementation of medical scientific and technological outcomes, and the cultivation of interdisciplinary talents.

Objective:To explore the management effect of information nurses in the reception of new surgical instruments and to provide a reference for improving the quality of instrument management in central sterile supply department.Methods:This was a quasi-experimental study. A total of 45 packages of 227 pieces received from January to July 2021 in central sterile supply department of the First Affiliated Hospital of Zhengzhou University were selected as the control group by convenience sampling method, and the conventional mode was used to receive new surgical instruments. Another 51 packages of 259 pieces received from November 2021 to June 2022 were selected as the observation group, and the information nurse management system was set up to receive new surgical instruments. The observation and comparison of the time to complete the receipt of new surgical instruments in central sterile supply department, the incidence of adverse events in the operation process and the satisfaction of medical and nursing staff with the management of new surgical instruments were conducted.Results:The receiving time for newly added surgical instruments of the observation group was 6.00(5.00, 8.00) hours and that of the control group was 28.00(20.00, 42.50) hours, with a statistically significant difference between the two groups ( Z = - 8.26, P<0.01). The incidence of adverse events of new surgical instruments was 0.4%(1/259) in the observation group and 6.2%(14/227) in the control group, there was significant difference between the two groups ( χ2 = 13.52, P<0.01). The satisfaction degree of medical staff in the observation group was 100% (50/50), higher than 72% (36/50) in the control group, and the difference between the two groups was statistically significant ( χ2 = 16.28, P<0.01). Conclusions:The implementation of the post of information nurse in the special post responsibility system in the management of new surgical instruments can effectively manage the specifications of surgical instruments, reduce the receiving time and the occurrence of adverse events, improve the satisfaction of medical staff.

Objective:To explore the influence of frequency of machinery heating power cleaning on dental handpiece loss and cleaning effect.Methods:This study selected 180 completely new high speed dental handpiece with machinery heating power cleaning. All of handpiece were randomly divided into group A, B and C, 60 cases in each group. Cleaning, oiling by special oiling machine, packing and sterilizing were carried out for the dental handpiece after being used. Group A, B and C implemented the process including machinery heating power cleaning, cleaning and oiling by special oiling machine, packing as well as sterilizing weekly, every other week and every three weeks respectively. This study randomly extracted 5 cases in each group to check the visible stains and monitor the cleaning effects after 3, 6 and 9 months.Results:Among group A, B and C, the using times were (56.60±24.77) , (49.70±30.08) , and (46.73±35.16) respectively with no statistical difference ( P=0.800) . There were 15 dental handpiece with trouble in 9 months, 4 in group A, 7 in group B and 4 in group C with no statistical difference ( P=0.660) ; 12 of them could be continued use after simple repair, 1 in group A, 7 in group B and 4 in group C with no statistical differences ( P=0.100) ; 3 of them could be continued use after changing central spindle, all in group A. The pass rates of visible cleanliness were all 100%. Conclusions:On the basis of cleaning and oiling by special oiling machine, machinery heating power cleaning every three weeks for dental handpiece can ensure the internal cleaning and improve working efficiency, but will not increase the loss.

OBJECTIVETo observe the clinical effects on analgesia, tranquilization and prevention of abortion syndrome of artificial abortion operation treated with transcutaneous electrical acupoint stimulation (TEAS) with different acupoint combination and explore the optimal acupoint combination of TEAS in artificial abortion operation.

METHODSTwo hundred patients intended to artificial operation were randomized into No.1 group[Sanyinjiao (SP 6) + Zusanli (ST 36)], No.2 group[Sanyinjiao (SP 6) + Diji (SP 8)], No.3 group[Sanyinjiao (SP 6) + Taichong (LR 3)], No.4 group (cervical blockage anesthesia with lidocaine) and No.5 group (blank group, without any analgesia measure applied), 40 cases in each one. In the No.1, No.2 and No.3 groups, Sanyinjiao (SP 6) was the main acupoint, combined with Zusanli (ST 36), Dijin (SP 8) and Taichong (LR 3) respectively. TEAS was given 30 min before the operation till the end of operation. Mean arterial pressure, heart rate and oxygen saturation during operation, as well as bleeding amount were observed in the five groups. The visual analogue scale (VAS) score was observed during and 30 min after operation, and Ramsay score was observed during operation. Cervical relaxation degree and the incidence of artificial abortion syndrome were recorded.

RESULTSFor VAS score during and 30 min after operation and Ramsay score during operation, the differences were significant statistically in the No. 1, No.2, No.3 and No.4 groups as compared with the No.5 group (<0.01,<0.05). The results in the No.2 group were better than those in the No.1, No.3 and No.4 groups (all<0.05). For cervical relaxationdegree, the result in the No.2 group was better than that in each of the rest groups (<0.01,<0.05). For artificial abortion syndrome, the incidences in the No.2 and No.3 groups were lower than those in the No.4 and No.5 groups (all<0.05). For bleeding amount and hemodynamic changes, the differences were not significant statistically among the five groups (all>0.05).

CONCLUSIONSTEAS apparently reduces pain score during and 30 min after artificial abortion operation and achieves the satisfactory tranguilization effects. The combination of Sanyinjiao (SP 6) and Diji (SP 8) achieves the optimal effect of analgesia, tranquilization, dilating cervix and preventing from artificial abortion syndrome in the operation.
