Objective To evaluate the prognostic role of bispectral index (BIS) monitoring in patients after cardiopulmonary resuscitation (CPR) in the intensive care unit (ICU).Methods Thirtythree adult patients after CPR were enrolled and divided into survived group and non - survived group as per 7-day survival.During their stay in the ICU,BIS and SaO2 (saturation of artery oxygen) levels of all the patients were continuously monitored.The neurological status of the patients was measured with Glasgow coma scale (GCS).Acute physiology and chronic health evaluation Ⅱ ( APACHE Ⅱ ) was used to evaluate the patient condition. SjO2 (saturation of jugular bulb venous oxygen ) levels of 23 patients were continuously monitored and then the difference in values between SaO2 and SjO2 was calculated to show oxygen metabolism in the brain. The studied variables were compared between the two groups. The correlations between BIS values and GCS scores,and between BIS and APACHE Ⅱ scores were respectively analyzed. Results The BIS values and difference in values between the SaO2 and SjO2 were significantly higher in the patients of survived group than those in the patients of non-survived group (P ＜0.01 ).There were positive correlation between BIS and GCS (r =0.821,P ＜ 0.01 ) and as well as positive correlation between BIS and APACHE- Ⅱ ( r =0.434,P ＜ 0.05 ).Conclusions The BIS may be useful to predict the post - resuscitative outcome of patients after cardiopulmonary resuscitation.

Objective:To observe the effects of lactoferrin(LF)on the proliferation,migration and osteogenic differentiation of human periodontal ligament cells(HPDLCs)in vitro.Methods:HPDLCs were cultured and identified.The proliferation and migration of HP-DLCs cultured with 0,10 and 20 μg/ml lactoferrin respectively were tested by MTT assay,Transwell assay and scratch test.The os-teogenic differentiation of the cells was evaluated using alizarin red staining and real-time PCR.Results:Lactoferrin at 10 and 20μg/ml increased the proliferation(P <0.05),increased the quantities of mineralized nodules and the expression of alkaline phospha-tase(ALP),osteocalcin(OCN)and osteopontin(OPN)(P <0.05).Conclusion:Lactoferrin promotes the proliferation,migration and osteogenic differentiation of HPDLCs.

Objective: To observe the protective effect of Silybin Capsules (SC) on mice hepatic toxic injury induced by isonicotinic acid hydrazide (INH) and rifampin (RFP) when used in combination Methods: The serum level of ALT, liver index, contents of glutathion (GSH) and malondialdehyde (MDA), activity of microsomal cytochrome P450 and its isoform P4502E1 in liver were measured. Results: SC obviously inhibited the rising of liver index, serum ALT, liver MDA and the activity of microsomal cytochrom P450 and its isoform P4502E1, and increased the liver GSH. Histopathological examination showed that Silibinin Capsules evidently alleviated the condition of the degeneration of hepatic cells and that of necrosis. Conclusion: The protective effect of SC on mice hepatic injury induced by both IIVit and RFP may be related to stabilizing the liver membrane, inhibiting the the lipid peroxidation, scavenging the free radical and decreasing the activity drug metabolizing enzyme.

Objective To investigate the role of phosphatidyl-inositol 3-kinase-Akt (PI3k-Akt) signal pathway in the attenuation of ischemia-reperfusion (I/R) injury by sevoflurane preconditioning in isolated rat hearts. Methods Ninety-six adult male SD rats weighing 220-280 g were randomly divided into 6 groups ( n = 16 each): sham operation group (group S); I/R group; sevoflurane preconditioning group (group SP); wortmannin group (group W); dimethyl sulfoxide (DMSO) group (group D) and sevoflurane preconditioning + wortmannin group (group SW) . Their hearts were excised and perfused in a Langendorff apparatus with K-H solution saturated with 95%O2-5%C02 at 37 ℃ . The hearts were continuously perfused for 180 min in group S. After 15 min of equilibration, the isolated hearts were subjected to 30 min of ischemia followed by 120 min of reperfusion in SP, W, D and SW groups. Croups SP, W, D and SW received 10 min of perfusion with K-H solution containing 2. 4% sevoflurane, 100 nmol/L wortmannin, 20 μmol/L DMSO, and 2.4% sevoflurane + 100 nmol/L wortmannin, respectively, followed by 5 min washout before I/R. Eight hearts in each group were selected and HR, left ventricular end-diabetic pressure (LVEDP), left ventricular developed pressure (LVDP), and ± dp/dtmax were recorded at the end of equilibration and at 15 min of reperfusion, Myocardial tissues were obtained at 15 min of reperfusion for determination of apoptosis (by TUNEL) and phosphorylated Akt (p-Akt) expression (by Western blot) . Another 8 hearts were selected at 120 min of reperfusion for determination of myocardial infarct size by TTC staining. Result Compared with group S, LVDP and ± dp/dt,^ were significantly decreased and LVEDP was significantly increased in groups I/R, SP, W, D and SW, and myocardial p-Akt expression was up-regulated in groups I/R, SP and D ( P ＜ 0.05). Compared with group I/R, LVDP and ± dp/dtmax were significantly increased, LVEDP and apoptosis index were significantly decreased, myocardial p-Akt expression was up-regulated, and myocardial infarct size was significantly reduced in group SP (P ＜0.05) . Conclusion Activation of PI3K-Akt signal pathway is involved in the attenuation of I/R injury by sevoflurane reconditioning in isolated rat hearts.

Objective To use the real-time shear wave elastography(SWE)to detect the elasticmodulus values of different breast lesions,and to assess its application value in differential diagnosis of benign and malignant breast lesions.Methods SWE was per-formed in 71 breast lesions from 63 pathologically confirmed patients.The maximum,minimum and mean elasticmodulus values in breast lesions were detected and the ROC curves were used to determine the optimal diagnostic cut off value.Results Among 7 1 le-sions,48 cases were benign lesions and 23 cases were malignant lesions.The diagnostic accuracy and Youden index of the ordinary ultrasound were 77.5% and 0.55 respectively.The maximum,minimum and mean elasticity values for malignant lesions were (106.7±37.9),(23.7±6.4),(44.8±6.6)kPa respectively,whereas which for benign lesions were(42.7±14.6),(17.2±6.3), (29.4±8.0)kPa respectively.The maximum,minimum and mean elastic values had statistically significant differences between be-nign and malignant lesions(P<0.05).The areas under the curve(AUC)of the maximum,minimum and mean elastic values were 0.963,0.798 and 0.914 respectively.Taking 78.1 kPa as the threshold of the maximum elasticity value,the sensitivity was 82.6%and the specificity was 95.8%.Taking 37.6 kPa as the threshold of the mean elasticity value,the sensitivity was 87.0% and the specificity was 83.3%.Conclusion SWE provides a new way for the differential diagnosis of benign and malignant breast lesions, and the maximum and mean elastic value can be used as the diagnostic evidence for differentiating benign and malignant breast le-sions.
