An introduction to the practice of introducing the“ surgeon qualification admittance system”in the hospital and a description of its management framework,basic principles,rules of classification for surgical operations,application and approval procedure,and supportive management regulations.The authors hold that this system has normalized behavior of medical activities,clarified operation authorities of medical doctors at various levels,and intensified the awareness of risk exposure.Therefore this system can safeguard the quality and safety of surgical operations and its efficiency to a great extent,in addition to better building the team and backup forces.

AIM: To observe the effects of norepinephrine (NE) on the cardiopulmonary and lung injury in goats with acute respiratory distress syndrome (ARDS) induced by endotoxin. METHODS: A model of septic ARDS was induced by intravenous infusion of low dose endotoxin in six goats. Then 40?10~ -6 NO inhalation was applied to the animals. After 30 min, combined intravenous infusion of NE at concentration of 0.5 mg?kg~ -1 ?min~ -1 was conducted. The dynamic changes in gas exchange and hemodynamics were measured with the aid of Swan-Ganz catheter. Arterial blood gas analysis before and after the onset of ARDS, 30 min after NO inhalation and combined NE was detected. Histology of the lung was also observed. RESULTS: Inhalation of NO rapidly reduced mean pulmonary arterial pressure (MPAP), increased PaO_2, decreased P_ (A-a) O_2 and Qs/Qt in septic ARDS goats. These decrease and increase were more significant than those in NO inhaled alone when animals received NE. The combination of NO inhalation and NE injection resulted in increase in mean arterial pressure. NO inhalation did not ameliorate lung injury and combined NE intravenous injection ameliorated lung injury. CONCLUSION: Injection of low dose norepinephrine improves the beneficial effects of inhaled nitric oxide on lung gas exchange and ameliorates lung injury in goats with acute respiratory distress syndrome induced by endotoxin.

Objective To investigate the tracking neurofibra pathway from the hippocamlpal neurons to septal nucleus,and to explore the effects and mechanisms of ghrelin on the learning and memory in septal nucleus lesion rats.Methods Retrogradely tracing method was used to observe Fluorogold (FG) reaching sites in hippocampus.The septal nucleus was destructed by direct current using stereotactic technique.Step-down test and morris water maze were used to test the effects of learning and memory ability by means of microinjecting ghrelin into hippocampal CA1 area in rats.Results After injection of FG into septal nucleus,retrogradely labeled neurons and neurofibra were found in the hippocampal neurons with FG.Ghrelin injection of hippocampal CAI area could promoter learning and memory ability in rats.It showed that the escaped latent period was significantly lengthened ( (3.2 ± 0.9) s vs (6.9 ± 1.1 ) s,P ＜ 0.05) and the wrong numbers in 5 min were obviously decreased in escape response test; and the latency of looking for the plat was significantly shorter in morris water maze test ( 1.8 ±0.4vs 0.8 ± 0.1,P ＜ 0.05 ).However the effects above-mentioned on learning and memory was significantly weak after septal nucleus lesioning.It showed that the escaped latent period was markedly shortened ( ( 19.5 ±3.2)s vs ( 10.5 ± 2.1 ) s,P ＜ 0.05 ) and the wrong numbers in 5 min were obviously increased ( ( 3.9 ± 0.8 ) s vs ( 1.8 ±0.5 ) s,P＜0.05 ) in escape response test.The latency of looking for the plat was significantly lengthened in morris water maze (P＜0.05).Conclusion Ghrelin could elevate the learning and memory ability in hippocampus,and the effects may be related to the septal-hippecampus pathway.

Objective To study the effects of electrical stimulation of efferent vagus nerve on the endotoxic shock in rabbits. Method Sixteen Newzealand rabbits were randomly divided into 2 groups, namely group S as the stimulation group and group C as the control group). Rabbits were subjected to bilateral cervical vagotomy and had challenge with intravenous injection of lipopolysaccharide (LPS) (E. COLI O111: B4 , DIFCO, USA) in a dose of 600 μg/kg. The distal end of the left vagus nerve trunk was connected to an electric stimulator with bipolar electrode and controlled by an acquisition system. Stimuli with stable voltage (10 V,5 Hz,5 ms) were applied twice to the nerve for 10 minutes just before and after the administration of LPS in group S. At the time before and after the infusion of LPS 30 min,60 min, 120 min, 180 min,240 min and 300 min respectively, the heart rate(HR)and the mean arterial blood pressure (MABP) in each animal were recorded, and blood samples were taken for measuring serum tumor necrosis factor-αa(TNF-α) and interleukin-10 (IL-10). Results Compared with group C,the electrical stimulation of efferent vagus nerve could significantly attenuated the LPS-induced hypotension and de-creased the contents of TNF-α[(38.12±7.85) pg/mL vs. (55.12±7.89) pg/mL, P <0.01], but increased the contents of IL-10[(55.12±9.37)pg/mL vs. (40.15±5.44) pg/mL, P <0.01]afar LPS challenge. Conclusions The stimulation of the efferent vagus nerve can down-regulate systemic TNF-α, production and attenu-ate the development of shock after LPS challenge.
