BACKGROUNDThe University of Wisconsin colloid based preserving solution (UW solution) is the most efficient preserving solution for multiorgan transplantation. Unfortunately, unavailability of delayed organ preserving solutions hindered further progression of cardinal organ transplantation in China. In this study, we validated an organ preserving Changzheng Organ Preserving Solution (CZ-1 solution) and compared it with UW solution.

METHODSA series of studies were conducted on how and how long CZ-1 solution could preserve the kidneys, livers, hearts, lungs and pancreas of New Zealand rabbits and SD rats. Morphology of transplanted organs was studied by visible microscopy and electron microscopy; biochemical and physiological functions and the survival rate of the organs during prolonged cold storage were studied.

RESULTSThere was no significant difference between CZ-1 and UW solutions in preserving the kidneys, livers, hearts or lungs of rabbits; kidneys, livers, intestinal mucosa or pancreases of SD rats or five deceased donors' testicles. In some aspects, such as preserving rabbits' hearts, rats' intestinal mucosa and pancreases, the effect of CZ-1 solution was superior to UW solution. CZ-1 could safely preserve kidneys for 72 hours, livers for 24 hours, hearts for 18 hours and lungs for 8 hours for SD rats. Twelve kidneys preserved in cold CZ-1 solution for 22 - 31 hours were transplanted successfully and the mean renal function recovery time was (3.83 +/- 1.68) days.

CONCLUSIONSCZ-1 solution is as effective as UW solution for organ preservation. The development of CZ-1 solution not only reduces costs and improves preservation of organs, but also promotes future development of organ transplantation in China.

PURPOSE: Numerous previous studies have reported inconsistent results about the differences between synchronous contralateral breast cancer (sCBC) and metachronous contralateral breast cancer (mCBC). This study aimed to compare the clinical characteristics and outcomes between sCBC and mCBC and determine predictive factors for the survival of sCBC and mCBC patients. METHODS: Using the Surveillance, Epidemiology, and End Results Program database, we identified sCBC or mCBC patients from 2000 to 2010. The Kaplan-Meier method and Cox proportional hazards regression analysis were used to analyze overall survival and breast cancer-specific survival (BCSS) rates of sCBCs and mCBCs, respectively. RESULTS: Overall, 14,057 sCBC (n = 8,139, 57.9%) and mCBC (n = 5,918, 42.1%) patients were included. The first tumors of sCBC were more likely to have higher stage and more lymph and distant metastases, whereas those of mCBC were more often infiltrating ductal carcinoma (IDC), had localized stage, were estrogen receptor (ER) and progesterone receptor (PR) negative, and had less axillary nodal involvement. The second tumors of mCBC tended to be IDC and have higher grade, adverse stage, ER and PR-negativity; and more axillary nodal involvement, compared to the second tumors of sCBC. mCBC patients had significantly favorable 5-year BCSS but worse long-term BCSS compared with sCBC patients. Moreover, subgroup analysis revealed no significant difference of BCSS between sCBC and mCBC among patients aged 18–60 years. Multivariate analysis indicated that age, grade, and stage of 2 tumors; surgery for second tumor; and ER status of the second tumor were independent prognostic factors for BCSS of contralateral breast cancer (CBC). CONCLUSION: The characteristics and outcomes of sCBCs and mCBCs were substantially different. sCBC and mCBC patients may have different prognosis, and the prognosis of CBC depends on the first and second tumors.

A new HPLC-UV technique for the separation and analysis of 10 monosaccharides achieved within 13.5 min using 1-phenyl-3-methyl-5-pyrazolone (PMP) as the labelling molecule of the reductive monosaccharides has been established by combining common high performance liquid chromatography-UV and C18 column. The established technique was applied to the quantification of the monosaccharide components in extract of Silybum marianum. The results showed that the tested 10 monosaccharides as PMP derivatives were baseline separated under the HPLC conditions proposed. It was confirmed that Silybum marianum extract was composed of mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, xylose, galactose and arabinose with the molar ratio of 0.66:0.84:0.58:1.0:1.6:0.69:2.7:4.8. Quantitative recoveries of the compositional monosaccharides separated from the extract were in the range of 92.4%-104.0%, and the RSD values fell within 0.68%-3.81%. The results demonstrated that the proposed HPLC method was simple, rapid, convenient, and precise, and it was applicable to the analysis of the compositional monosaccharides of Silybum marianum extract.

In order to evaluate the incidence of chromosomal abnormalities in patients with polycythemia vera (PV) accurately and to investigate the value of fluorescence in situ hybridization (FISH) technique in the detection of trisomies 8 and 9, conventional cytogenetics (CC) technique was used to detect karyotype and interphase FISH was used to detect trisomies 8 and 9 in 50 newly diagnosed PV and 8 normal individuals. The results showed that out of 50 cases, the 3 cases had chromosome karyotype abnormality, including trisomy 8, deletion of chromosome Y and inversion of chromosome 11 by CC technique. FISH method detected two cases of trisomy 8, including one case confirmed by CC technique, and one case of trisomy 9 neglected by CC technique. It is concluded that the incidence of chromosomal abnormalities in patients with PV is rare, and the incidence of trisomy 8 and trisomy 9 found in this study are relatively lower than that have been reported which may be related to the limited number of samples. Interphase FISH, as an important complement to CC, is a useful method for the detection of trisomies 8 and 9.
