In vivo imaging system (IVIS) is a new and rapidly expanding technology, which has a wide range of applications in life science such as cell tracing. By counting the number of photons emitted from a specimen, IVIS can quantify biological events such as tumor growth. We used B16F10-luc-G5 tumor cells and 20 Babl/C mice injected subcutaneously with B16F10-luc-G5 tumor cells (1x10(6) in 100 muL) to develop a method to quantitatively analyze cells traced by IVIS in vitro and in vivo, respectively. The results showed a strong correlation between the number of tumor cells and the intensity of bioluminescence signal (R (2)=0.99) under different exposure conditions in in vitro assay. The results derived from the in vivo experiments showed that tumor luminescence was observed in all mice by IVIS at all days, and there was significant difference (P<0.01) between every two days from day 3 to day 14. Moreover, tumor dynamic morphology could be monitored by IVIS when it was invisible. There was a strong correlation between tumor volume and bioluminescence signal (R (2)=0.97) by IVIS. In summary, we demonstrated a way to accurately carry out the quantitative analysis of cells using IVIS both in vitro and in vivo. The data indicate that IVIS can be used as an effective and quantitative method for cell tracing both in vitro and in vivo.

Objective To study the effects of oral rehydration with the solution of pyruvate-glucoseelectrolyte (PGES) by comparison with the bicarbonate-glucose-electrolyte solution (BGES) on resuscitation in rats with lethal hemorrhagic shock.Methods Sixty adult male SD rats with intra-gastric tube,and cannulation of femoral artery and vein were subjected to 45％ total blood volume loss from the femoral artery,and then randomly divided into three groups (n =20 in each group):no fluid resuscitation group (NR),oral fluid resuscitation with the PGES group (PGES) and oral fluid resuscitation with the BGES group (BGES).In NR group,the animals received no fluid replacement or any other treatment.Rats in PGES and BGES groups were infused intra-gastrically with pre-warmed PGES or BGES in volume of 2 times shed blood given at 30 min after hemorrhage and completed within 6 hours.Blood samples in each group were collected from the abdominal aorta before or at 0,1,2,4 h post hemorrhage to detect serum alanine aminotransferase (ALT),creatinine (Cr),creatine phosphate kinase isoenzyme (CK-MB) and intestinal fatty acid binding protein (iFABP).Another 84 rats randomly divided into four groups:NR group (n =24),PGES group (n =24),BGES group (n =24),and no hemorrhage group (NH group,n =12).Rats in the three hemorrhage groups were treated the same as described above,and the rats in NH group underwent the same surgical procedure without hemorrhage were served as the sham group.All these rats were observed for their 24-hour survival rates.Results The 24-hour survival rates of PGES and BGES groups were both significantly higher than the rate of NR group (11/24 vs.1/24,x2 =18.087,P ＜0.01 ; 5/24 vs.1/24,x2 =6.445,P ＜ 0.05) ; the survival rate of PGES group was also significantly higher than that of BGES group (11/24 vs.5/24,x2 =4.02,P ＜ 0.05).All levels of ALT,CK-MB,Cr and iFABP in both the NR group and two oral resuscitation groups at 1 h,2 h and 4 h post hemorrhage were significantly higher than those before the blood loss,respectively (P ＜ 0.01).These biomarkers at 2 h,4 h post hemorrhage were significantly lower in the PGES and BGES groups than those in NR group (P ＜ 0.01) ; the serum levels of ALT,CK-MB,Cr and iFABP were significantly lower in the PGES group than those in the BGES group at 2 h and 4 h post hemorrhage,respectively (P ＜ 0.05).Conclusions Present results demonstrated that the pyruvate-enriched oral re-hydration solution (ORS =PGES) was more effective in preserving the organ function and prolonging the animal survival after resuscitation of lethal hemorrhagic shock in comparison with the bicarbonate-containing ORS (BGES).The oral re-hydration solution (PGES) recommended by the World Hygiene Organization (WHO ORS) may require further improvement in oral resuscitation of shock and the PGES may be recommended as a choice of oral re-hydration salts in the treatment of lethal hemorrhagic shock when intravenous administration is not available.

Objective To investigate the effects of prophylactic antiviral therapy for HBV DNA negative HBV-relat-ed hepatocellular carcinoma (HCC) patients undergoing hepatic arterial chemoembolization (TACE). Methods Fifty-four consecutive patients with HBV-related HCC and received TACE were enrolled in this study. Thirty patients received pre-emptive antiviral drugs before TACE were defined as the treatment group. Twenty-four patients, who did not use antiviral drugs until HBV reactivation after TACE, were included in control group. The incidence of HBV reactivation, duration from HBV DNA positive point to the last time of TACE, the occurrence of abnormal alanine aminotransferase (ALT) caused by HBV reactivation, the peak of aspartate aminotransferase (AST) and the number of liver failure caused by HBV reactivation were observed after TACE in two groups. Results The incidence of HBV reactivation, the occurrence of abnormal ALT, the occurrence of abnormal ALT caused by HBV reactivation, the peak ALT and peak AST were significantly lower in treatment group than those of control group (P ＜ 0.05). No liver failure caused by HBV reactivation was found in treatment group. There were four patients with liver failure caused by HBV reactivation in control group. There was no significant difference in cumulative survival rate between two groups (P=0.071). Conclusion It is suggested that preemptive antiviral therapy can prevent the reactivation of hepatitis B virus, prevent the deterioration of liver function,and decrease the occurrence of liv-er failure caused by HBV reactivation in patients receiving TACE.
