Objective To investigate the clinical significance of the changes of hemodynamics and electrolyte during orthotopc liver transplantation.Methods We studied 9 patients undergoing elective orthotopic liver transplantation without venovenous bypass,drew out arterial blood for monitoring arterial blood gas tensions,Na~+,K~+,Ca~(2+) and observed changes in hemodynamics and electrolyte.Results In most patients,arterial pressure significantly decreased at the prophase of the anhepatic phase,and tended to normal range in other phases.The concentration of calcium maintained a low-level during the whole surgery.During the prophases of the anhepatic phase and neo-hepatic phase,there was a light hyperkalemia,and the concentration of natrium slightly increased since 30 minutes after the anhepatic phase and neohepatic phase,but insensibly exceeded normal range.With resuming of the stability of hemodynamics,these changes had followed.Conclusion We shoud give our attention to correct the occurrence of the hypocalcemia during the forepart of the anhepatic phase and neo hepatic phase,and care for the hyperkalemia 5 minutes after the block of liver blood purveyance and revascularization of liver.The lock of body capability shoud be recruit duly according to the lose of blood and hemacytometer changes.In order to prevent serious academia and maintain the stability of hemodynamics and electrolyte,vasoconstrictor shoud be used carefully during the anhepatic phase.

Objective To investigate the effects of health management on risk factors of cardiovascular diseases in community residents.Methods A total of 208 adults from one single community who visited our health check-up center were randomly assigned to the control group(receiving routine consultation,n =104)and health management group(receiving health management intervention,n =104).At 1-year follow-up,fasting blood glucose(FBG),lipid profiles,and blood pressure(BP)were measured and risk factors of cardiovascular were surveyed.t or x2 test was used for data analysis.Results No difference of clinical data was found between the two groups at baseline.Follow-up results indicated that absolute risk of cardiovascular diseases,number of risk factors,health satisfaction,sick leave,daily vegetables intake and physical exercise,and BP were significantly improved in the health management group.Ten-year absolute risk of cardiovascular diseases(0.8 ± 0.4 vs 1.3 ± 0.5),number of risk factors(172 vs 283),and sick leave per year(118 d vs 264 d)were significantly decreased in the health management group when compared to the control group(all P ＜ 0.05).Furthermore,health satisfaction(83.7％(87/104)vs 52.9％(55/104)),and daily vegetables intake(520.5 g vs 348.3 g)and physical exercise(1.2 h vs 0.3h)were significantly improved in the health management group(all P ＜ 0.05).Conclusion Health management may be effective in decreasing risk factors of cardiovascular diseases in community residents.

Objective To observe the effect of early enriched environmental intervention on synaptic ultrastructure and the synaptophysin expression (p38) in hippocampal CA1 area after hypoxia-ischemic brain damage(HIBD) in neonatal rats. Methods The rat model of HIBD was made by the method of Rice in 20 Sprague-Dawley rats, and divided randomly into 2 groups: the intervention group, non-intervention group. Another 10 rats underwent sham-operation as control. From the second day after HIBD, the rats of the intervention group were kept in an enriched environment for 20 d, the rats of non-intervention group and sham-operation group were raised in standard enviroment instead. The hippocampal ultrastructure was observed with electron microscope and the p38 expression was detected immunohistochemically in all rats. Results The ultrastructure of hippocampus CA1 pyramidal neuron in the non-intervention group were distorted as compared with that in the intervention group and control group. The corrected optical densities (COD) of immunoreactive products of the hippocampal p38 were significantly decreased in non-intervention group as compared with intervention group and control group (P0.05). Conclusion Early enriched environment intervention could improve the synaptic reconstruction and reduce the ultrastructural damage induced by hypoxic-ischemia.

Objective To observe the effects of different environment stimulation on the nestin expression in hippocampus and the ability of learning and memory of rats after hypoxic-ischemic brain damage (HIBD). Methods Rat HIBD models were established by the method of Rice in 45 SD rats, then randomly divided into three groups: standard environment stimulation group (SE), enriched environment stimulation group (EE), and impoverished environment stimulation group (IE). Another 15 rats only underwent sham-operation. Different environment intervention that was designed according to Puurunen and Bourgeon’s literatures was applied to the rats on day 2 after HIBD operation. On day 28, Morris water maze was used to evaluate the ability of learning and memory. Then the nestin expression in the hippocampus was measured by immunohistochemistry. Results The ability of learning and memory of IE group reduced and was much lower than that of sham-operation group, SE group and EE group, that of SE group was lower than that of sham-operation group and EE group, but no significant difference between sham-operation group and EE group. Immunohistochemical analysis showed that nestin expression in the hippocampus of EE group significantly increased as compared with that of other groups and that of SE group was stronger than that of sham-operation group and IE group. Conclusion The EE stimulation could increase the nestin expression in the hippocampus of neonatal rats with HIBD, enhance neuranagenesis, and improve the ability of learning and memory, while the IE stimulation could decrease the nestin expression, inhibit neuranagenesis, and impair the ability of learning and memory.

Objective To observe the effects of early enriched environment intervention on the expression of growth-associated protein-43(GAP-43) in the hippocampus of rats with hypoxic-ischemic brain injury (HIBI). Methods After the establishment of HIBI model in SD rats by the method of Rice, the animals were divided randomly into 2 groups: the intervention group and non-intervention group. The sham-operation rats were used as control group. Enriched environment intervention had been administrated to the rats of intervention group since the 2nd day after HIBI. On the 3rd, 7th, 14th, 21st and 28th day, immunohistochemistry and RT-PCR were used to measure the expressions of GAP-43 protein and mRNA in the hippocampus of rats. Results The expression of GAP-43 protein and mRNA in the rat hippocampus were increased in the non-intervention group than in the control group(P

Objective To observe the effects of environmental stimulation at different stages of development on postnatal rats with hypoxia-ischemic brain injury (HIBI). Methods HIBI postnatal SD rats models were established by dissecting and ligating the left common carotid artery, and after 2 h of recovery, exposing to 8% oxygen-92% nitrogen gas mixture for 2 h. The HIBI rats were randomly divided into early intervention groups, late intervention group, non-intervention group. Intervention group were kept in enriched environment before or after weaning for 20 d. Non-intervention group and control group were kept in a standard environment. Space learning and memory were tested with Morris water maze. Results The ability of space learning and memory in early intervention group was better than that in late intervention group (P

Objective To observe the expression of growth-associated protein-43(GAP-43) in the hippocampus of neonatal rats with hypoxic-ischemic brain damage (HIBD). Methods HIBD was established by the method of Rice in 48 SD rats aged 7 days and another 48 matched normal rats served as control. Immunohistochemistry and RT-PCR were respectively used to detect the expression of GAP-43 protein and mRNA in all rat hippocampus on day 8, 10, 14, 21, 28, 35 after HIBD (n=8 at each time point for each group). Results The expression of GAP-43 protein and mRNA in hippocampus was obviously increased in HIBD rats as compared with normal rats, the peak of GAP-43 protein appeared at 3rd week, and the peak of mRNA at 2nd week. Conclusion The expression of GAP-43 protein and mRNA increased in the hippocampus of rats following HIBD, which was possibly related to the recovery of injured hippocampus.

Objective To investigate the response of retinal ganglion cells (RGC)in detached and reattached retina in adult rats, and the effect of IL-1beta antibody and IL-1Ra on the loss of RGC. Methods A total of 73 Sprague-Dawley (SD) rats were subretinally injected with healon GV(1.4% hyaluronate)and retrograde labeled with fluorogold (FG), and 10 ng IL-1Ra and 500 ng IL-1beta antibody were injected into the subretinal space combined with healon GV. The retinal flakes were observed under the fluoroscope and the number of RGC was counted 2 hours, 1, 3, 5, 7, 10, 20, 50, and 90 days after detachment; 10 days after detachment and 30 days after reattachement; 90 days after detachment and 20 days after reattachement, and 1 and 10 days after injection with IL-1beta antibody and IL-1Ra,respectively. And the control group was only developed an intraocular injection of the same valume of healon GV. Result Two hours after detachment, the RGC loss was found, reached the peak at first day, and decreased gradually. RGC loss was also found in the non-detached area. The reattachment 10 days after detachment (early reattachment) stopped the loss of RGC, and the reattachment 90 days after detachment (late reattachment) promoted the loss, which rested on a certain level. Subretinal space injection of IL-1Ra and IL-1beta antibody decreased the loss of RGCs in the detached retina. Conclusion The RGCs loss were found both in the detached and attached retina. Early reattachment may stop the loss of RGC, and late reattachment may promote the loss. Both IL-1beta antibody and IL-1Ra have neuroprotective effect on RGC.
