Objective To investigate the effects of 17-β estradiol on hepatocyte apoptosis and the expression of Bcl-2 and Bax in hepatic tissue after reduced-size ischemia reperfusion injury and its mechanism in liver protection.Methods A rat model of reduced-size hepatic ischemia-reperfusion injury was established in 75 male Sprague-Dawley rats.They were randomly allocated into three groups:Sham group,ischemia-reperfusion(IR)group,and 17-β estradiol(E2 + IR)group.Liver functions,liver histology and hepatocellular apoptosis rates were observed after reperfusion.Hepatocellular ap optosis was determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL)method and the expression of Bcl-2 and Bax were determined by Western blotting.Results The levels of ALT and AST were higher and peaked after 12 h of reperfusion in the IR group compared with the sham group.The histological changes in the liver of the IR group consisted of hepatocyte swelling,hepatic sinusoids narrowing,inflammatory cell infiltration and hepatocyte necrosis in some areas of the livers.The IR group also exhibited an increased rate of hepatocellular apoptosis at 12 h after reperfusion.The protein expression of Bcl-2 decreased while the expression of Bax increased.In the 17-β estradiol group,the levels of ALT and AST were lower,the pathological changes were milder and the rate of hepatocellular apoptosis was lower at 12 h in comparison to those of the IR group.The expression of Bcl-2 was higher and the expression of Bax was lower in the 17-β estradiol group in comparison to those of the IR group.Conclusions 17-β estradiol can relieve the hepatic ischemia reperfusion injury in rat livers.17-β estradiol may inhibit apoptosis in hepatic tissue by up regulating Bcl-2 and down-regulating Bax,thus producing a protective effect on hepatic ischemia-reperfusion injury.

Objective: To provide an effective hGM CSF gene transferring vector mediated by gene gun and a basis for study of hGM CSF gene modified tumor cell vaccines. Method: The gastric tumor cell line (SGC) was transfected with eukarytic expression plasmid deoxyribonucleic acid containing the human granulocyte macrophage colony stimulating (hGM CSF) gene using the gene gun. The SGC cell clones (SGC GM CSF 1~5)secreting high hGM CSF level were obtained after G418 resistance selection. The hGM CSF gene had been integrated into chromatosome of SGC by the assay of RT PCR.Results: There was hGM CSF production whose lane was about 30 kD in the culture medium of SGC GM CSF by the assay of SDS PAGE and Western blot. SGC GM CSF had the ability of the high level of GM CSF for a long time(mean 247ng/(10 6 cell?24 h).Conclusion: The hGM CSF gene transferring vector mediated by gene gun was effective and safe. These results provide a basis for study of GM CSF gene therapy for cancer.

OBJECTIVE:To investigate the inhibitory effects mechanism of scallop skirt glycosaminoglycan(SS-GAG)on inju-ry in human umbilical vein endothelium cells (HUVEC). METHODS:In the test,there was a negative control group,a model group and the groups of SS-GAG at high,middle and low concentrations(mass concentrations of 200,100 and 50 mg/L respective-ly). The cells in latter 3 groups were cultured in SS-GAG at different mass concentrations for 12 h,and then in 50 μmol/L oxidized low-density lipoprotein(OX-LDL)for 24 h. MTT method was used to detect cell viability and the activity of lactic dehydrogenase (LDH),the flow cytometer to determine the level of reactive oxygen species (ROS),real-time fluorescence quantitative poly-merase chain reaction (RT-PCR) to detect mRNA expression of lectin-like oxidized low-density lipoprotein receptor 1 (LOX-1), and Western blot to detect NOX4 protein expression. RESULTS:Compared to the cells in the negative control group,those in the model group demonstrated lower viability,higher activity of LDH,higher level of ROS,and stronger expressions of LOX-1 mRNA and NOX4 protein. There was statistical significance (P<0.01). Compared to the cells in the model group,those in the groups of SS-GAG at high,middle and low concentrations showed higher viability,lower activity of LDH,lower level of ROS and weaker expressions of LOX-1 mRNA and NOX4 protein. There was statistical significance (P<0.01). CONCLUSIONS:SS-GAG can protect HUVEC to some degree by a mechanism which may be related to inhibiting ROS production via LOX-1/NOX4 pathway and relieving oxidative stress injury.

ObjectiveTo evaluate the one-year follow-up of the therapeutic efficacy of human umbilical cord derived-mesenchymal stem cell (UC-MSC) transplantations in decompensated liver cirrhosis patients with ascites.MethodsFifty-four liver cirrhosis patients with ascites in Research Center for Biological Therapy in 302 Military Hospital were divided into treatment group (n=38) and control group (n=16) in a prospective controlled single-blinded trial.UC-MSC (0.5-1.0) × 106/kg and saline were intravenously transplanted into patients monthly for 3 times in treatment group and control group,respectively.The liver function,hepatitis B virus (HBV) DNA level,ascites and the model for end-stage liver disease(MELD)scores at different time points were compared between two groups.The comparison between groups was done by Mann-Whitney U test,and the data before and after transplantations were compared by Wilcoxon signed rank sum test.ResultsThere were no significant differences of alanine transaminase (ALT),total bilirubin (TBil),cholinesterase (CHE),HBV DNA positive rate and MELD scores at different time points between two groups (P>0.05).However, the albumin ( A1b)level was significantly increased after 36 weeks of UC-MSC transplantation in treatment group, which were (28.47±4.45)g/L at week 0 and ( 34.82±4.50)g/L at week 48 (P=0.046). Meanwhile, the ascites reduced markedly in treatment group with (46.6 ±30.6) mm at week 0 and (6.6±13.6) mm at week 48,which were significantly different from control group at the end of follow-up (P =0.037). Conclusion UC-MSC transplantations may help to increase A1b level and reduce ascites in patients with decompensated liver cirrhosis.

Objective To investigate the clinicopathologic features and treatment of thyroid microcarcinoma (TMC). Methods From January 1997 to December 2006,311 patients who underwent surgery and defined as TMC(tumor size≤1 cm)were enrolled. Results TMC was identified incidentally by frozen pathologic examination on thyroidectomy specimens in tentative benign goiters in 181 patients; another 130 patients with clinically detectable primary tumors or suspected nodal metastases were grouped to as clinically overt TMC. The clinically overt TMC had a higher incidence of bilateral multifocal tumors (18.5%vs.9.4%,P=0.03),and cervical lymph node metastases(27.7%vs.10.5%,P=0.000)than that in clinically occult TMC group. Conclusion TMC may vary considerably in clinical and biologic behaviors between these two subtypes: clinically overt and occult. Lobectomy for single lesion, total or near total thyroidectomy for multifocal with central compartment nodal dissection should be performed, lateral nodal dissection was not carried out unless US or physical examination detected nodal metastases. Lobetomy, subtotal or more limited thyroidectomy for occult TMC, diagnosed incidentally following thyroid surgery for initially tentative benign thyroid disease, could all be treatment of choice depending on the preference of surgeons.

A series of noscapine analogues have been synthesized via 13-step reaction starting from 2-hydroxy-3-methoxybenzaldehyde. Anti-tumor activities of these compounds were evaluated against HL-60 cell lines in vitro by the standard MTT assay. It was found that most of these derivatives showed appreciable inhibitory activity against HL-60 and tubulin polymerization. The results also indicated that the potency of compound 31 is about three times more than that ofnoscapine against HL-60 cell line and tubulin polymerization. Moreover, it induced a massive accumulation of cells in G2/M phase. These results showed noscapine and its derivatives were worth to be intensively studied further.
