ObjectiveTo identify the proteins presented variation during ischemia/reperfusion injury (I/RI) in liver transplantation (LT).MethodsAt Mar.2009,a total of nine liver sample tissues,three samples obtained from each donor liver at three different time points,were studied.The time points were as follows:(1) the time point immediately after donor liver was harvested (T1) ; (2) the time point just before the anastomosis of hepatic artery and potal vein (T2),during this time period the donor liver was kept in ice cold and transported,then back-table prepared,during time from T1 to T2,ischemia injury occurred; (3) the time after donor reconnected to the recipient (T3),during which the donor liver was subjected to reperfusion injury.The three time points represent normal control,ischemia injury,and reperfusion injury respectively.By using method of 2DE-MALDI-TOF and mass-spectrum,the differential expression of these protein at T1,T2,and T3 time point were compared.ResultsFrom the 1580 proteins that were isolated,19 ischemia/reperfusion injury (I/RI)-related proteins that varied markedly from time point T1 to T2 and from time point T2 to T3 were identified.They were metabolic enzyme,molecular chaperone,redoxase,cytoskeleton protein,signal transduction protein,and binding protein,respectively.The character of each protein was further analized based on their functions.ConclusionsFor the first time,we detected the protein related to I/RI during LT.We obtained independent proteomics information of ischemia injury,and reperfusion injury,respectively.Further functional analyses of these proteins may improve the understanding of the critical biological processes during I/RI.Medicine intervention on the I/RI-related proteins may result in improved survival of the recipients.

Objective:To explore the effect of Zinc finger protein 185 (ZNF185) on the migration of human gliocytoma cells. Methods: ZNF185 protein expression in human gliocytoma and its adjacent normal tissues was detected through Western blot. The ZNF185 gene was cloned and transfected into the human gliocytoma cell line SF767. ZNF185 cells were located through immunofluo-rescence staining, and cell migration was analyzed using the cell scoring method. Results:CZNF185 protein expression was lower in the human gliocytoma cell line than in normal para-neoplastic tissues. ZNF185 protein was mainly expressed in the cytoplasm and cell membrane of the human gliocytoma cells and was co-located with F-actin. ZNF185 overexpression repressed the migration of human gliocytoma cells. Conclusion:ZNF185 represses the migration of human gliocytoma cells by binding to F-actin.

AIM　To establish innovational triangular phase diagrams for preparation of pharmaceutical microemulsion (ME) with low toxicity as a result of reducing the amount of the emulsifiers. METHODS Lecithin and polyoxyethylene octyl phenyl ether (OP) were used as emulsifiers (E), absolute alcohol and n-octyl alcohol as assistant emulsifiers (A), ethyl oleate and olive oil as the oil phase (O). For the innovational triangular phase diagrams, lecithin-ethyl oleate-water and absolute alcohol (optimized ratio W/A=0.6)system, and OP(olive oil and n-octyl alcohol (O/A=0.34)-water system were used for preparation of the ME. While for the traditional triangular phase diagrams, OP and n-octyl alcohol (E/A=Km=1.5)-olive oil-water system, lecithin and absolute alcohol (E/A=Km=1.12)-ethyl oleate-water system were used. Then, the corresponding amounts of the emulsifiers used in both methods were compared. RESULTS　In the ME of lecithin systems by the innovational and the traditional methods, the amounts of emulsifier are 6%-28% and 28%-29.6%, respectively. In the ME of OP systems by the innovational and the traditional methods, the amounts of emulsifier are 23%-40% and 27.6%-49.8%, respectively. CONCLUSION　The method of innovational triangular phase diagram for preparation of ME is superior to the traditional method in finding out the lower amounts of emulsifiers for ME, and is a feasible method with guiding significance for preparing ME.

Renal cancer is a common malignant tumor in urology, with complicated pathogenesis and no obvious clinical symptoms. Metastatic renal cancer accounts for 20%-30% of the newly diagnosed renal cancer. The 5-year survival rate for metastatic patients is less than 10%.At present, the main non-surgical treatment means of mRCC include cytokines and targeted drug therapy, and immunotherapy has also become a research hotspot of mRCC. The current status and research progress of mRCC therapy were reviewed. The medical treatment methods of metastatic renal cancer, such as receptor tyrosine kinase inhibitors and mTOR inhibitors; immunotherapies, such as immunosuppressants for PD-1/PD-L1 were also discussed.

AIM　To improve the treatmemt efficacy and reduce the side effect of carboplatin (CBP), the antitumor drug was incorporated into niosomes (NS). METHODS　Lung targeted niosomes of CBP (CBP-NS) were prepared by the method of hand shaking. The ultraviolet absorption spectrophotometric method was used for the determination of CBP. The method of dynamic dialysis was used for in vitro release of CBP from CBP-NS. The S-180 lung neoplasms models were established by iv cancer cells in mice. The number of pulmonary nodules was examined for evaluating the therapeutic efficacy. RESULTS　The data showed that the mean diameter of CBP-NS was 3.72 μm, with a span of 0.66. The entrapment ratio of CBP in CBP-NS was 29.2% and the CBP-NS were stable for three months stored at 3℃-5℃, 15℃-25℃ or 37℃ (relative humidity 75%). The release profile in vitro could be described by a biexpotential equation. The calculated values of the three targeting parameters indicated that CBP-NS showed good targeting efficiency. The results of therapeutic trials showed that the antitumor effects were significantly increased by injection of CBP-NS compared with CBP in the treatment of mice with lung carcinoma. CONCLUSION　The results indicated that CBP-NS have good targeting efficiency in vivo, and the biodegradable CBP-NS may decrease the side effects of carboplatin and improve its therapeutic efficacy.

Objective To explore the role of zinc finger protein (ZNF)185 in the proliferation of human glioma cells. Methods Human glioma tissues and tumor adjacent tissues were obtained from glioma patients diagnosed pathologically in Tangshan Gongren Hospital from January 2011 to December 2013. Total protein was extracted from different tissues. The ZNF185 expression was detected by Western-blot assay. Total RNA was extracted from tumor adjacent tissues. ZNF 185 cod?ing sequence was obtained by RT-PCR and inserted into pEGFPC2 plasmid to construct the ZNF185 expression vector. Li?pofactamine2000 was used to transfect the ZNF185 expression vector to human glioma cell SF767. pEGFPC2 blank vector transfected SF767 cells were used as control. Changes of cell cycle were analyzed by flow cytometry, and cell proliferation was analyzed by MTT assay. Results The expression of ZNF185 decreased significantly in human glioma tissues compared to that of tumor adjacent tissues(P<0.01). The over expression of ZNF185 in SF767 resulted in the increased proportion of cell cycle G0-G1phase, but decreased proportion of S phase(P<0.05). Furthermore, the cell proliferation was significantly inhibited in the ZNF185 over-expressed SF767 cells compared with that of blank vector transfected cells(P<0.05). Con?clusion ZNF185 plays an inhibitory role in cell proliferation of human brain glioma cells.

The therapy of removing beat and toxic,strengthening the body to cultivate the fundamental is the mainstream of treating cancer in traditional Chinese medicine up to now,and the therapy of warming yang has been rarely involved.While the pathogenesis of tumor is spleen and kidney yang deficiency in root,and phlegm,stasis,and poison entangled with each other at the secondary position; the main therapeutical principle of tumor is simultaneous application of purging-tonifying therapy while focusing on protecting yang.The author believes that the treatment of cancer should pay attention to the whole concept,especially warming yang for patients with advanced tumors.The therapy of warming yang is an effective way to get rid of phlegm and blood stasis.Patients after radiotherapy and chemotherapy should be paid more attention to warming yang.
