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 investigate the value of thyroid transcription factor-1(TTF-1) in the diagnosis and biological behavior assessment of hepatocellular carcinoma (HCC). Methods Thirty liver specimens obtained from benign lesions were analysed, among which 25 were hepatic cirrhosis and inflammatory diseases, and the other 5 were adenomas. And there were 176 specimens of liver tumors, among which 142 were HCC (well differentiated, n=12; moderately differentiated, n=57; poorly differentiated, n=73), 17 were intrahepatic cholangiocellular carcinoma (ICC) and the other 17 were liver metastatic carcinoma (MC). The expression of TTF-1 was examined immunohistochemically in the above tissues, and the difference in expression of TTF-1 among different tissues was examined by Fisher's exact test, Kruskal-Wallis test and Spearman rank correlation analysis. Results TTF-1 was significantly expressed in the cytoplasms of all the hepatocytes besides tumors and liver benign lesions. The expression rate of TTF-1 in HCC was 78.9% (112/142), however, TTF-1 was negatively expressed in ICC and MC(P

OBJECTIVETo explore the effect differences between twirling-rotating reinforcing and reducing technique of acupuncture on cardiac damage in spontaneous hypertensive rats (SHR).
METHODSSixty male 11-week-old SHR were randomly divided into four groups: a model control group (group A), a twirling-rotating reinforcing technique group (group B), a twirling-rotating reducing technique group (group C) and a needle retaining group (group D), 15 rats in each one. In addition, twelve male 11-week-old Wistar rats were used as a blank control group (group E). Acupuncture was not used in group A and group E, only with grasp, capture and binding stimulation that was also adapted in the rest groups. Rats in the group B were treated with acupuncture at "Taichong" (LR 3) by twirling-rotating reinforcing technique for 1 min and then the needles were retained for 9 min; rats in the group C were treated with acupuncture at "Taichong" (LR 3) by twirling-rotating reducing technique for 1 min and then the needles were retained for 9 min; rats in the group D were treated with acupuncture at "Taichong" (LR 3) but without any technique and then needles were retained for 10 min. Before and after acupuncture, blood pressure monitor was used to measure the rats' systolic pressure and diastolic pressure every 6 days. Twenty-eight days after the treatment, HE and Masson staining were adopted to observe the status of left ventricular hypertrophy and myocardial fibrosis. ELISA method was applied to test the content of endothelin-1 (ET-1). PCR semiquantitative method was used to analyze Type I and III collagen mRNA in the left ventricular.
RESULTS(1) Blood pressure: after the treatment, the systolic pressure and diastolic pressure were both increased in the group A and the group B (P < 0.05); while the two pressures were both lowered in the group C and the group D (P < 0.05), which was more obvious in the group C (P < 0.05). (2) According to HE and Masson staining, except for the group E, the myocardial hypertrophy and fibrosis could be found in the rest groups, in which the group C was the modest, followed by the group D, while the group A and the group B were more severe. (3) Concentration of ET-1: there were differences of concentration of ET-1 among 5 groups (P < 0.05), and the concentration value from high to low was the group A, B, C, D and E. (4) Type I collagen mRNA: the difference of level of Type I collagen mRNA between group C and D was not statistically significant (P > 0.05); compared with the group A and B, the level was lower in the group C; the level was the lowest in the group E. Type III collagen mRNA: the difference between the group A and B was not statistically significant (P > 0.05); compared with the group A, B and D, the level was lower in the group C.
CONCLUSIONThe twirling-rotating reducing could reduce the systolic pressure and diastolic pressure in SHR, effectively prohibit the production of ET-1 and expression of Type I and III collagen mRNA, and it has more obvious inhibiting effect on Type III collagen mRNA. There is biological effect difference between twirling-rotating reinforcing and reducing technique.
