Objective To compare the application of Goldman , CARPREG and ZAHARA in predicting cardiac outcomes in pregnant women with congenital heart disease. Methods A retrospective analysis of 144 pregnant women with CHD , enrolled in The Third Affiliated Hospital of Guangzhou Medical University between Jan 1992 and June 2015 was conducted. The mortality and the incidence of cardiac events were counted by three risk estimation methods. The sensitivity and calibration of three systems were compared by using Hosmer-Lemeshow goodness of-fit analysis and Aera Under Curve (AUC). Results In terms of mortality rates, the sensitivity of CARPREG was higher than that of Goldman (AUC:0.874 and 0.889 respectively;P = 0.568 >0.05);. In terms of the incidence of cardiac events, the sensitivity of ZAHARA was higher than that of Goldman (AUC:0.912 and 0.773 respectively;P = 0.063 > 0.05); Conclusions All 3 risk estimation methods have good performance in sensitivity of predicting the incidence of cardiac events and mortality in pregnant women with CHD. The ZAHARA has a better calibration in predicting the incidence of cardiac events , and we recommend ZAHARA as the first choice of evaluation system for this kind of patients.

Objective To investigate the clinical application value of hand-assistant laparoscopy and total laparoscopy in radical right colectomy.Methods Five hundred and twenty-four patients were selected as our subjects who performed by hand-assistant laparoscopic radical right colectomy (213 cases) or total laparoscopic radical right colectomy (293 cases) in colon cancer therapy.The operation durations,bleeding volumes,postoperative pain scores,postoperative draining volumes,recovery time of gastrointestinal function,hospitalization times,hospitalization expenses,postoperative complications and cosmetic satisfactory scores were recorded and compared.Results The operation durations,bleeding volumes,postoperative draining volumes in hand-assistant laparoscopic group were (112.4±52.9) min,(105.6 ± 49.5) ml,(28.6± 15.7) ml,lower than those in total laparoscopic group((148.5±61.7) min,(171.5±72.4) ml,(28.6±15.7) ml;P=0.032,0.041,0.039).The recovery time of gastrointestinal function of hand-assistant laparoscopic group were (69.4±21.8) h,longer than total laparoscopic group ((53.4 ± 21.7) h;P =0.008).The hospitalization times,hospitalization expenses,postoperative complications of hand-assistant laparoscopic group were as same as total laparoscopic group(P＞0.05).Hand-assisted laparoscopic group mild pain in 35 cases,121 cases of moderate and severe 75 cases;Total 96 cases of mild pain in laparoscopic group,146 cases of moderate and severe in 51 cases,the difference was statistically significant(P=0.027).Beauty score incision of laparoscopic group was higher than in the whole hand-assisted laparoscopic group,the difference was statistically significant ((4.3 ± 0.9) score vs.(2.4±0.6) score;P=0.002).Conclusion Hand-assistant laparoscopic radical right colectomy is convenient and more quickly for operation.Total laparoscopic radical right colectomy has advantage in terms of less injury and the patients are more satisfactory.For practiced operators,total laparoscopic radical right colectomy is recommended cosmetic satisfactory score.

BACKGROUND: A lot of important organs are worthless for clinical application because they are hard to store for a long time. In addition, tissues or organs which are dealt with cryopreservation also attack ischemia/reperfusion injury with the recovery of blood flow; especially, skeletal muscle is the most involved tissue.OBJECTIVE: To observe the protective influence of edaravone on cellular membrane and mitochondria of replanted rat extremities following ischemia/reperfusion injury due to cryopreservation and rewarming.DESIGN: Randomized contrast animal study.SETTING: Basic Medical College of Southern Medical University; Department of Hand and Foot Surgery, Shandong Provincial Hospital.MATERIALS: The experiment was carried out in the Cryopreservation Laboratory, Shandong Provincial Hospital from April to November 2006. A total of 36 healthy adult male Wistar rats were provided by Experimental Animal Center of Medical College of Shandong University. All rats were randomly divided into control group, cryopreservation group and edaravone group with 12 in each group.METHODS: Femoral artery and vein of rats in control group were exposured, but extremities were not blocked. Rats in other two groups were used to establish ischemia/reperfusion injury models of replanted extremities. Before cryopreservation, their right hindlimbs were cut off and maintained in liquid nitrogen container for 1 month. After the operation mentioned above, the broken limbs were rewarmed, perfused with routine eluant and replanted. Four hours later, blood supply of extremities was recirculated and the samples were selected. Eluant in edaravone group contained 0.5 mg/kg edaravone. Samples of skeletal muscle were selected at the same time point to establish cellular membrane and extract mitochondria. Furthermore, fluorescence polarization of cellular membrane (reflecting liquidity in cellular membrane lipid area), malondialdehyde (MDA) content of mitochondria, superoxide dismutase (SOD) activity and respiratory controlling rate were measured; meanwhile, mitochondrial ultrastructure of skeletal muscle was observed under transmission electron microscope.MAIN OUTCOME MEASURES:①Fluorescence polarization of cellular membrane, MDA content of mitochondria, SOD activity and respiratory controlling rate of skeletal muscle; ②mitochondrial ultrastructure of skeletal muscle.RESULTS: All 36 rats were involved in the final analysis without any loss. ①SOD activity and respiratory controlling rate of mitochondria in skeletal muscle: The values of these two items were higher in edaravone group that those in cryopreservation group (P＜0.05).②Fluorescence polarization of cellular membrane and MDA content of mitochondria in skeletal muscle: The values of these two items were lower in edaravone group than those in cryopreservation group (P＜0.05). ③Mitochondrial ultrastructure of skeletal muscle: Injured degree of skeletal muscle was milder in edaravone group than that in cryopreservation group.CONCLUSION: Edaravone can relieve ischemia/reperfusion injury of skeletal muscle and protect cellular membrane and mitochondria of skeletal muscle. Its mechanism may be related to directly inhibiting hydroxy free radicals, increasing SOD activity of skeletal muscle, reducing generation of MDA and promoting normal oxidative phosphorylation.

Objective To explore the impact of ischemic stroke on intestinal barrier changes in dogs.Methods Totally 20 mongrel dogs were divided into 2 groups by random number table with 10 in each.Double silicone cylinders measuring 1.1 mm in diameter and 8 mm in length were placed into their internal carotid arteries in all dogs of group A.Group B served as a control group and received sham operation.Light microscopy was performed for morphological measurement of intestinal epithelial cell.Immunohistochemistry was used to analysis the changes of protein zonula occludens-1(ZO-1)localizing at tight junction of intestinal epithelial cells.Results Ischemic stroke was confirmed by cranial CT scanning in all dogs of group A.Compared with the test results in group B,the occludin and Zo-1 protein levels in group A were significantly lower than those in group B(occludin:0.20 ±0.01 vs 0.22 ±0.01,P =0.007; ZO-1:0.20 ±0.01 vs 0.22 ±0.02,P =0.008).The apoptotic index in group A was significantly higher than in group B(29.04 ± 3.79 vs 6.44 ± 1.24,P =0.002).There was a positive correlation between occludin and ZO-1(R =0.71,P =0.02),and the apoptotic index was negatively correlated with levels of occludin,ZO-1(R =-0.91,P =0.00; R =-0.77,P =0.01).Light microscopy showed that the dogs in group A had intestinal mucousal injuries while no obvious change was detected in group B.Conclusions Dogs with ischemic stroke tend to develop intestinal barrier dysfunction,during which the destruction of tight junction plays a key role.The up-regulated apoptosis of intestinal epithelial cell constitutes one of the cellular bases of intestine injury.
