BACKGROUND:How to control functional activity of donor liver after cardiac death and maintain the optimal function of grafts are the key issues in organ transplantation study.
OBJECTIVE:To preliminarily explore the effect of warm ischemia injury on the morphology and function of rat donor liver after cardiac death.
METHODS:Cardiac death model was established in Sprague-Dawley rats and the successful models were divided into six groups:control group (warm ischemia for 0 minute), warm ischemia 10 group (warm ischemia for 10 minutes), warm ischemia 20 group (warm ischemia for 20 minutes), warm ischemia 30 group (warm ischemia for 30 minutes), warm ischemia 40 group (warm ischemia for 40 minutes) and warm ischemia 50 group (warm ischemia for 50 minutes). The rat liver specimens in each group were cut into ultrathin sections. The structure of liver cells was observed and photographed by electron microscopy. Flameng score was applied to analyze the degree of mitochondrial damage. Liver mitochondria were extracted and then spectrophotometry was used to assess the viability of cytochrome C oxidase.
RESULTS AND CONCLUSION:Under electron microscopy, there were no significant changes in liver cells within 30 minutes of warm ischemia, nuclear membrane was intact, mitochondria mildly swel ed, no mitochondrial crista ruptured, and Flameng score was<2 points. With the extension of warm ischemia time, the cells became swel ing, nuclear chromatin condensated, apoptotic body was clearly visible, mitochondrial matrix coagulated, mitochondria exhibited vacuolation, and Flameng score was 3-4 points. The viability of cytochrome C oxidase showed no significant difference within 30 minutes of warm ischemia, but began to significantly decrease at 40 and 50 minutes. The mitochondrial structure and function after liver injury is not obviously affected by 30 minutes of warm ischemia, and significant changes appear after 40 minutes.

Objective:This paper aimed to investigate the effects of isocorydinone on cell proliferation in SiHa human cervical carcinoma cell lines. Methods:Different concentrations of isocorydione (100, 200, 400, 800, and 1200 μmol/L) were used to treat SiHa human cervical carcinoma cells in vitro for 24, 48, and 72 h. Methyl thiazolyl tetrazolium (MTT) assays were conducted to determine the inhibitory action of isocorydione. Flow cytometry was performed to detect the cell cycle in SiHa human cervical carcinoma cells af-ter treatment with 400 μmol/L isocorydione. Hoechst 33342 staining was used to observe the micro-morphological changes of SiHa cell nucleus after the treatment. The expression of Bcl-2, Bax, and caspase-3 proteins in cervical carcinoma SiHa cell lines was determined using western blot analysis. Results: MTT assays showed that isocorydione inhibits the proliferation of SiHa cells in a dose- and time-dependent manner (P<0.05). The flow cytometry results showed that SiHa cervical carcinoma cells treated with different concen-trations of isocorydione exhibited increased cell cycle. Compared with the control group, Hoechst 33342 staining showed that SiHa cells became narrow, with nuclear pyknosis and fragmentation, and formed an apoptotic body after treatment with 400 μmol/L isocoryd-ione for 48 h. Furthermore, western blot analysis proved that isocorydione significantly inhibited the proliferation of SiHa cell lines, and the expression of Bax protein was increased. By contrast, the expression of Bcl-2 protein decreased gradually. Consequently, the ra-tio of Bax/Bcl-2 increased, as well as the expression of caspase-3 protein. Conclusion:Isocorydione exhibited an overt inhibitory ac-tion on SiHa cells. Isocorydione promoted the occurrence of cell apoptosis, which may be associated with related proteins of mitochon-drial apoptotic pathway.

BACKGROUND:The aquaporin (AQP), mainly AQP1, AQP4 and AQP9, are expressed in mammalian brain, while the others are sporadical y expressed. There is no evidence concerning the distribution, function and regulation mechanism of AQP in the brain.
OBJECTIVE:To comprehensively analyze the research progress of the distribution, function and regulation mechanism of AQP in maintaining normal physiological function of the brain.
METHODS:An online retrieval of PubMed database and CNKI database between January 1980 and July 2013 was performed for articles on the distribution, function and regulation mechanism of AQP, with the key words of“AQP1, AQP4, AQP9, function, brain, adjusting mechanism”in English and Chinese. A total of 163 papers were screened out and 85 of them met the inclusive criteria.
RESULTS AND CONCLUSION:The existing studies about the expression, function and regulating mechanism of AQP1, AQP4 and AQP9 in the brain can be summarized as the fol owing three aspects: (1) AQP1 is expressed in the choroid plexus and participates in forming cerebrospinal fluid;in other types of cells, gas micromolecules CO 2 , NO, NH 3 and O 2 also cross through AQP1. (2) AQP4 is mainly expressed in the astrocytes, ependymal foot process and gelatin membranes, which can help the water in and out of the brain tissue, accelerate glial cellmigration and change neural activity. (3) AQP9 is mainly distributed in astrocytes and catecholamine neurons, the main function is involved in energy metabolism in the brain. Therefore, AQP is the key for water transport in the brain. Understanding the distribution, function and regulation mechanism of AQP wil play an important role in the treatment of brain diseases. The regulatory mechanism on the expression of AQPs in normal pathology and related disease remains unclear and related molecular signal pathway needs further exploration.

Objective To evaluate the efficacy and safety of treating liver cancer using 131I-anti-CD147-monoclonal-antibody (131I-anti- CD147-McAb) by transcatheter hepatic arterial infusion (TAI) in a rabbit liver cancer model. Methods Forty-five rabbit models were randomly divided into three groups evenly. Transcatheter hepatic artery infusion under general anesthesia were performed in all three groups. Group A:control group, saline. Group B:pure 131I solution. Group C: 131I-anti-CD147-McAb solution. About 2 ml blood sample was obtained from all rabbits for liver, kidney,and thyroid function at pre-TAI and post-TAI 1 day, 3 days ,7 days, 14 days, 21 days. The rabbits were scanned by single photon emission computed tomographic (SPECT) to monitor radionuclide bio-distribution and tumor size on 1 day, 7 days, 14 days, 21days after procedures in group B and C. On 14 days after procedure, five rabbits were randomly selected to be sacrificed in each group for pathological and immunological investigations. The remaining rabbits continued to be fed, and survival rates were measured. Results The TAI and SPECT-CT/CT procedures were successfully performed in all rabbits. Test results showed that AST and ALT levels tended to increase transiently 1 day after TAI (P<0.05). The liver function returned to pre-operative levels (P> 0.05) 7 days after TAI. FT3 and FT4 mean values of rabbits in group B and C continued to decline 7 days after TAI, while thyroid stimulating hormone (TSH) showed corresponding increase (P<0.05). WBC mean value of rabbits in group B and C declined slightly after procedures (P>0.05). SPEC-CT imaging of rabbits shows that most of the radionuclide was gathered in the gastrointestinal tract and thyroid in Group B, however, radionuclide was mainly concentrated in the tumor lesions in Group C. Fourteen days after procedures, radionuclide imaging of all rabbits disappeared in group B and C. The VX2 liver tumors increased rapidly after treatment in group A and B;but the tumors gradually reduced their size in group C. At 14 days after TAI: The proportion of tumor necrosis in group C was significantly greater than that in groups A and B (P<0.05). The microvessel density (MVD) number of residual tumor in group C was less than groups A or B (P<0.05).TUNEL analysis suggested that more apoptosis bodies was displayed in the residual tumor tissue in group C than that in groups A and B, but the expression of MMP-2 and vessel endothelial grouth factor (VEGF) was significantly reduced in group C than group A and group B. Median survival time of the rabbits in groups A, B, C was 22 days, 26 days and 54 days respectively. Survival time of the rabbits in group C was significantly prolonged than other two groups (P<0.01). Conclusions Radioimmunotherapy with 131I-anti-CD147-McAb by TAI can inhibit the growth and metastasis of liver cancer, and prolong the survival of experimental animals. The method is effective and safe in this animal study.
