Objective:To assess the survival-predictive value of TNM and Lugano staging systems in patients with primary gastro-intestinal lymphoma (PGL). Methods:A total of 73 patients with PGL were recruited from February 2001 to August 2013. All patients were diagnosed according to the TNM and Lugano staging systems. Five-year survival rate was used as the major clinical outcome. Sur-vival curves were plotted using the Kaplan–Meier method and analyzed with the log-rank test. The prognostic value of different vari-ables for clinical outcomes was assessed using the Cox multiple regression model. Results:The median follow-up time of surviving pa-tients was 42.4 months (range:1.3-158.6 months). The estimated 5-year overall survival rate was 77.82%. When diagnosed with the TNM system, the 5-year survival rates in stagesⅠ,Ⅱ,Ⅲ, andⅣwere 100%, 90.0%, 67.4%, and 22.2%, respectively (χ2=17.7956, P=0.0005). When staged by the Lugano system, the 5-year survival rates in stagesⅠ,Ⅱ,ⅡE , andⅣwere 100%, 100%, 70.7%, and 46.2%, respectively (χ2=15.6776, P=0.0013). Cox analysis showed that the invasion depth (T) (P=0.0181) and metastasis (M) (P=0.0031) were covariates that were prognostically significant for the overall survival. Conclusion:The TNM staging system is more ac-curate than the Lugano system in predicting the 5-year survival rate of patients with PGL.

ISG15, the first ubiquitin-like molecule identified two decades ago, is encoded by interferon stimulated gene 15 ( ISG 15), where its robust expression can be induced by viral infections or interferon treatments. ISG 15 conjugate to other proteins as the ubiquitin and was found to be involved in innate immune response. However, the functions of ISG15 modification remained unclear. We cloned bovine ISG15(bisg15) into a prokaryotic expression vector pET28a( + ) with a His-tag to generate a soluble form of bISG15 fusion protein, and purified with Ni-NTA Sepharose chromatography. The purified protein was concentrated and used to immune Balb/c mice to raise the antiserum, which could specifically recognize bISG15 expressed in eukaryotic cells by Western blot analysis. The concentrated bISG15 protein and its antiserum were then used to establish an in vitro bISG15 modification system. Our studies have demonstrated that cellular proteins could be conjugated to bISG15 with this system.

This study was aimed to establish an HPLC method for simultaneous content determination of valtrate, acevaltrate, and their degradation products, which were baldrinal and 11-ethoxyviburtinal, in Valeriana jatamansi Jones. The separation and quantification of 4 constituents mentioned above were performed on an Agilent ZORBAX SB-C18 (4.6 mm×250 mm, 5 μm). The mobile phase consisted of water (A) - acetonitrile (B) with an optimized gradient program. The flow rate was 1 mL·min-1. The column temperature was set at 25℃. The wavelength was set at 241 nm. And the injection volume was 10μL. The results showed that among 14 different places of V. jatamansi, the 4 contents determined were different. The contents of valtrate, acevaltrate, and baldrinal in the Yunnan Baoshan Mount were the highest. And the content of 11-ethoxyviburtinal was the highest in Yunnan Dali. It was concluded that the method was with good precision, reproducibility and stability. And it was suitable for the determination of 4 valepotriates ingredients in V. jatamansi. It also provided references for the quality control and exploitation of V. jatamansi.

To explore novel coumarin derivatives with more potent anti-proliferative activity, a series of novel compounds were designed and synthesized by linking Schiff base and N, N-bis (2-chloroethyl) amine pharmacophore of nitrogen mustards to the coumarin's framework. Their structures were confirmed by 1H NMR, MS and element analysis techniques. In vitro anti-proliferative activities were evaluated against HepG2, DU145 and MCF7 cell lines by the standard MTT assay. The results showed that some of the target compounds exhibited strong anti-proliferative activities against selected tumor cells, and compounds 7c, 7f, 7g, 7h and 7q were better than or equal to the activities of positive control, they deserved further development.

BACKGROUND: Removal of immunosuppressants in patients with recurrent tumor in long-term following organ transplantation is always a hot controversial point in academic circles. To further elevate clinical efficiency, people began to invent new immunosuppressant and studied immune efficiency of various immunosuppressant component. They tried to reduce the application of cyclosporin A (CsA).OBJECTIVE: To analyze the CsA safe withdrawal of a case of kidney recipients, at 18 years after renal transplantation, who developed bladder carcinoma and renal pelvic carcinoma at 11 years and 18 years after transplantation, respectively. METHODS: After identified diagnosis, we performed transurethral resection of bladder tumor (TURBt) and total nephroureterectomy merobladder excision. Pathologic examination revealed grade Ⅰ-Ⅱ of bladder and renal pelvic transitional cell carcinoma. After the operation, patient was treated with immune suppression program of CsA withdrawal gradually in 12 days.Within 12 days, 5 mg CsA was decreased every 3 days, and complete withdrawal was done at 12 days. The dosage of azathioprine tablets and prednisone acetate tablets was not changed. Serum creatinine levels were rechecked every 3 days during drug withdrawal, and blood pressure, urine volume, physical symptom of patients and ultrasound of transplanted kidney were observed.RESULTS AND CONCLUSION: During the three months of CsA withdrawal, the blood creatinine levels were from 65 to indicated that the CsA gradually withdrawal of a case of kidney recipients after renal transplantation, who developed transitional cell carcinoma and was performed transurethral resection of bladder tumor (TURBt) and total nephro- ureterectomy merobladder excision, was safe. No tumor relapse or diversion was found.
