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 assess the impacts of management of psychological health on metabolic indictors in community residents.Methods A total of 300 health check-up adults from one single community were randomly assigned to the control group (receiving routine health management,n =150) and the study group (receiving psychological health management,n =150).Blood pressure (BP),fasting plasma glucose (FPG),total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C) and life style were evaluated and compared at baseline and 1-year follow-up.Results No difference of clinical data was found between the two groups at baseline.After 1-year intervention,current sigarette smoking,BP,FPG,TC,TG and LDL-C of the study group were significantly decreased when compared with the control group (x2 =7.54,t =6.43,5.38,5.89,6.15,4.36,6.69,5.47 ; all P ＜ 0.05).Compliance to and satisfaction with health management were significantly improved in the study group (x2 =9.13,12.35,11.96,10.98,9.95 ; all P ＜ 0.05).Conclusion Management of psychological health may be effective in improving healthy life style,patients' satisfaction and cardiovascular metabolism in community residents.

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.

In order to study the angiogenesis in endometriosis, the samples of eutopic and ectopic endometria from patients with endometriosis were quantitatively analyzed by color morphometric image system (CMIS) for vascular surface area, and by examining endometrial blood vessel for microvessel density (MVD). The results showed that within each menstrual phase the vascular surface area and MVD were significantly higher in ectopic endometria with endometriosis than those in eutopic endometria with endometriosis or normal endometrium (P < 0.05). It is concluded that angiogenesis might be involved in the development of endometriosis.

Objective To observe the effect of maternal deprivation(MD)on learning and memory ability and hippocampal pathology and nestin expression in rats with hypoxic -ischemic brain damage (HIBD).Methods The models of HIBD SD male rats were established by the method of Rice,and were randomly divided into 2 groups:MD group and control group.In addition,the sham -operation group(sham group)models were established.The MD group rats were separated from their mother 3 hours per day from the second day after modeling to the 21 st postnatal day.After 28 postnatal days,Morris water maze was used to evaluate the learning and memory ability of the rat models.HE stai-ning was employed to observe the hippocampal pathological change in the rats.Then,the expression of nestin in the hip-pocampus was measured by the method of immunohistochemistry.Results Their body mass changes showed that quali-ty of sham group was higher than that of the control and the MD groups,and quality was improved in the control group, compared with the MD group,and the differences were statistically significant(q =9.860 8,3.880 7,5.980 1 ,all P <0.05).The water maze scores of the MD group in place navigation test and spatial probe test were much lower than that of the control group and the sham group,and the scores of the sham group were higher than that of the control group,the differences were statistically significant(all P <0.05 ).The findings of HE stain showed that the pathology in the right -sided hippocampus of the sham group was normal and neurons were well -arranged,and that of control group was minimally abnormal,and the neurons were almost arranged orderly and remained normal.While,the pathomorpholo-gy of the MD group was obviously abnormal,the neurons were arranged disorderly,many of the neurons lost.According to the immunohistochemical findings,the number of nestin -positive cells in right -sided hippocampus of the MD group was significantly less than that of the control group,and the number of nestin -positive cells of the sham group was less than that of the MD group,which showed significant differences among the groups(all P <0.05).Conclusions MD aggravated injury to learning and memory ability of neonatal rats with HIBD,and decrease the number of nestin -posi-tive cells of MD markedly,which is not good for the recovery of brain injury.

Objective To study the neurodevelopmental outcome prospectively at 18 months of the late preterm infants.Methods Data from 7 584 live born neonates were collected between January and December.2009 in 3 hospitals located in the north of Chengdu City,Sichuan Province were collected,89 late preterm infants were brought into study ; 170 healthy full-term infants were chosen as the controls randomly.Neurodevelopment outcome was assessed by using neonatal behavioral neurological assessment(NBNA) at 40 weeks corrected gestational age,and Bayley scales of infant development was performed to obtain the physical development index (PDI) and mental development index (MDI) at 3,6,9,12 and 18 months corrected age.Neurodevelopmental outcome of late preterm infants was studied compared with that of the term infants.Results Sixty-three neonates born at the late preterm phase and 115 neonates born at the term phase were successfully followed up.The NBNA scores of the late preterm infants at 40 weeks corrected gestationa] age were significantly lower than those of the term infants.The proportion of the late preterm infants whose scores ≥37 was significantly lower than that of the term infants(82.5％ vs 94.8％),the proportion of late preterm infants whose scores ＜35 was significantly higher than that of the term infants(4.8％ vs 0),the proportion of the late preterm infants whose scores in 35-36 was significantly higher than that of the term infants (12.7％ vs 5.2％,Z =-2.707,P ＜ 0.05) ;At 3,6,9 and 12 months corrected age,the late preterm infants showed a significant lower PDI scores(t =-4.266,-4.594,-5.663,-2.584) and MDI scores (t =-7.121,-7.829,-7.038,-6.002) than those of the term infants(all P ＜0.05).Compared with the term infants,the late preterm infants still had lower MDI scores than the term infants at 18 months corrected age(t =-4.115,P ＜0.05),but no difference was observed in PDI scores between late preterm and the term infants (t =-0.957,P ＞ 0.05).Conclusions Neurodevelopment outcome of the late preterm infants is delayed in the first year compared with term infants.At 18 months corrected age the mental development is still delayed compared with the term infants.Measures should be taken properly to improve the neurodevelopment of the late preterm infants in the early childhood.

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.

Objective To investigate the expression of E-cadherin in prostate cancer and its relationship with PSA. Methods E-cadherin expression of 56 prostate cancer samples were studied by immunohistochemical stain and its expression level was analyzed with respect to T-PSA, F-PSA and F/T ratio. Results 24 patients (43%) were normal and 32 patients (57%) were aberrant in E-cadherin expression. E-cadherin was related significantly to the grade and stage of cancer and the changes of F/T ratio.There were no significant relationship between E-cadherin expression and T-PSA or F-PSA. Conclusions E-cadherin expression may act as a marker to the malignant degree and the prognosis of the prostate cancer.

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
