We herein report a witnessed cardiopulmonary collapse of a patient with difficult mask ventilation and near-impossible laryngoscopy-cum-intubation in the critical care unit. The airway was successfully rescued with a laryngeal mask airway Supreme™, followed by an open, crash tracheostomy by the otolaryngologist.

The ABCD2 score is validated for evaluating short-term stroke risk after transient ischemic attack (TIA); however, whether it is able to predict the long-term risk of vascular outcome remains uncertain. Recently a new tissue-based definition of TIA has been proposed. The ABCD2 scores of 145 TIA patients admitted to our hospital were retrospectively calculated and stratified into two categories: ≤ 3 points (low risk); 4-7 points (moderate-high risk). At a median follow-up of 81 months, new vascular events were recorded. Follow-up data were available in 107 patients. Seventy one patients had a moderate-high ABCD2 score. Sixty six patients experienced a cerebral ischemic event; 8 a myocardial infarction; 7 died of cerebrovascular or cardiovascular cause. Moderate-high ABCD2 score was significantly associated with the further cerebral ischemic events (hazard ratio [HR], 1.755; 95% confidence interval [CI], 1.019 to 3.024) and with the combined endpoint (HR, 1.818; 95% CI, 1.079 to 3.063). Our study shows that the ABCD2 score may also be used to predict long-term vascular outcome after tissue-based definition of TIA. Moderate-high ABCD2 score is associated with an increased general vascular risk in the long-term follow-up after TIA.

Fuzi is a medicine used for rescuing from collapse by restoring yang as well as a famous toxic traditional Chinese medicine. In order to ensure the efficacy and safe medication, Fuzi has mostly been applied after being processed. There have been different Fuzi processing methods recorded by doctors of previous generations. Besides, there have also been differences in Fuzi processing methods recorded in modern pharmacopeia and ancient medical books. In this study, the authors traced back to medical books between the Han Dynasty and the period of Republic of China, and summarized Fuzi processing methods collected in ancient and modern literatures. According to the results, Fuzi processing methods and using methods have changed along with the evolution of dynasties, with differences in ancient and modern processing methods. Before the Tang Dynasty, Fuzi had been mostly processed and soaked. From Tang to Ming Dynasties, Fuzi had been mostly processed, soaked and stir-fried. During the Qing Dynasty, Fuzi had been mostly soaked and boiled. In the modem times, Fuzi is mostly processed by being boiled and soaked. Before the Tang Dynasty, a whole piece of Fuzi herbs or their fragments had been applied in medicines; Whereas their fragments are primarily used in the modern times. Because different processing methods have great impacts on the toxicity of Fuzi, it is suggested to study Fuzi processing methods.

Background The construction of tissue-engineered corneal endothelium and corneal endothelial cells (CECs) therapy need abundant seed cells,so how to culture a large amount of CECs with high viability and original cell properties is an urgent issue to be solved.Objective This study was to establish three-dimensional spheroid culture of CECs and explore the cellular biological characteristics.Methods Primary rabbit CECs were isolated with trypsin and subcultured.Low attachment and shaking culture was applied to form CECs spheres.Cultured cells were identified under the inverted microscope.The surface features of the cells were examined under the scanning electron microscope.The viability of the cells were assayed by acridine orange (AO) staining and CCK-8 kit.Then CECs spheres were incubated to 6-well plate for 1 week,and immunofluorescence staining was used to identify the expression of zonula occludens-1 (ZO-1) and Na+/K+-ATPase in the cells.The cell proliferation value of spheroid culture method was compared with that of regular culture method.Results CECs grew into aggregation after cultured with the hexagonal or polygonal shape and tight connection among the cells.The cells converged into single layer and slabstone-like arrangement 1 week later.Cells migrated out of the CECs sphere and formed an uneven spherical surface.The living cells showed green fluorescence for AO with the survival rate 90％.The absorbance (A450) of the cells was 1.524±0.013 and 1.265 ±0.021 in the spherical culture group and conventional culture group,respectively,showing a significant difference between them (t =-3.436,P=0.010).The positive cells of ZO-1 and Na+/K+-ATPase showed the green fluorescence for FITC on cell membrane and blue fluorescence for DAPI on cell nucleus.Conclusions Spherical culture method maintains a high viability and proliferation ability of the cells and remains phenotype of CECs,which is superior to conventional culture method.This culture method provides better seeding CECs for the establishment of tissue engineering cornea endothelial layer and CECs therapy.

Objective To investigate the trend of early neural development in premature infants. Methods At the age of 12 months and 24 months, Bayley Scales of Infant Development were used to assess the mental development index (MDI) and the psychomotor development index (PDI) in preterm (corrected age) and full-term infants. Results At 12 months, there was no significant difference in corrected age PDI scores among different gestational age groups (<32 , 32–33+6 and 34–36+6 weeks) (P=0.820). The actual age MDI and PDI scores of full-term infants and premature infants in 34~36+6 weeks group were significantly higher than those of premature infants in <32 and 32-33+6 weeks groups, and the PDI score of full-term infants was significantly higher than that of premature infants in 34-36+6 weeks group (P<0.05). There was no significant difference in actual age PDI scores among different birth weight groups (P=0.166). The actual age MDI and PDI of full-term infants and premature infants in birth weight≥2500 g group were significantly higher than those of premature infants in <1500 g, 1500~1999 g and 2000~2499 g groups (P<0.05). At 24 months, the actual age MDI scores of full-term infants were significantly higher than those of premature infants in different gestational age and birth weight groups (P<0.05). The actual age MDI curve of premature infants in birth weight <1500g group showed a downward trend, while the actual age PDI curve showed a significant upward trend. Conclusion The neurodevelopment of preterm infants at the corrected age of 12 and 24 months reaches the level of full-term infants.

Objective To investigate the effects of emulsified isoflurane preconditioning on myocardial NF-κB activity during ischemia-reperfusion(I/R)in rats.Methods Forty-eight healthy male SD rats weighing 230-280 g were randomly divided into 4 groups with 12 animals in each group: sham operation group(group S),I/R group,lipid emulsion + I/R group(group L)and emulsified isoflurane + I/R group(group EI).In group I/R,EI and L,myocardial I/R was produced by occlusion of left coronary anterior descending artery(LAD)for 30 min followed by 120 min reperfusion.In group L,30% lipid emulsion 4 ml·kg-1 ·h-1 was infused intravenously for 30 min before myocardial I/R.In group EI,emulsified isoflurane 4 ml· kg- 1 · h- 1 was infused intravenously for 30 min followed by 15 min washout before myocardial I/R.In group S and I/R,normal saline was given instead.Blood samples were taken from femoral artery at the end of 120 min reperfusion for determination of serum cTnI and IL-6 concentrations and CK-MB activity by ELISA.The rats were then killed and the myocardial tissues were taken for determination of NF-κB activity by Western blot and observation of the ultrastructure by electron microscopy.Results The NF-κB activity,serum cTnI and IL-6 concentrations and CK-MB activity were significantly higher in group I/R,EI and L than in group S(P ＜ 0.05 or 0.01),while lower in group EI than in group I/R(P ＜ 0.05).Microscopic examination showed that emulsified isoflurane significantly attenuated the histopathological changes in group EI.Conclusion Emulsified isoflurane pretreatment can attenuate myocardial I/R injury through decreasing the NF-κB activity and inhibiting inflammatory response in rats.
