Objective To analyze the clinical features of primary splenic lymphoma. Method Clinicopatholngie features of 29 patients with primary splenic lymphoma treated in Cancer Hospital, Chinese Academy of Medical Sciences from November 2000 to August 2008 were analyzed retrospectively. Results In this study 27 cases were confirmed to be non-Hodgkin's lymphoma (NHL), and 2 cases were of Hodgkin's lymphoma (HL). According to Ahmann's staging, 6 cases belonged to stage Ⅰ, 4 was stage Ⅱ, and 19 was stage Ⅲ. Twenty-six patients received spleneetomy, 2 cases did splenectomy plus pancreatic body and tail resection, and 1 case did spleneetomy plus partial gastrectomy. Postoperatively, 19 cases received chemotherapy, and 5 of the 19 patients received rituximab (Mabthera) treatment. One patient received radiotherapy for regional lymph node invasion. The median time of follow-up was 24 months (range, 2 -93 months). The l-year, 3-year and 5-year overall survival rates were 96%, 83% and 73%, respectively. The 1-year, 3-year and 5-year disease-free survival rates were 96%, 51% and 51%, respectively. Conclusions Primary splenic lymphoma is the most common malignant tumor of the spleen. Splenectomy combined with excision of invaded tissues or organs is important therapy for patients with primary splenic lymphoma. Comprehensive treatments including chemotherapy, radiotherapy and biotherapy are recommended after operation.

Objective To assess the feasibility and indications of local resection as an alternative to pancreaticoduedenectomy for the treatment of early stage ampullary cancer. Methods In this study,36 patients with an AJCC.stage pTl ampullary carcinoma were operated on between 1989 and 2009.Among those local resection was performed in 11 cases and pancreaticoduodenectomy in 25 cases.The main outcome measures were pre-and intra-operative diagnosis and staing,postoperative morbidity and mortality,recurrence.free and overall survival.Results Amp-llary cancerat early stageWas difficult to be diagnosed and staged before and during operation.It was at a much lower risk to perform local resection than pancreaticoduodenectomy.Postoperative complications were significantly lower in local resefion group than in pancreaticoduodenectomy group(P=0.031);whereas the postoperative hospital stay(P=0.254),perioperative mortality(P=1.000).disease-free survival(P=0:301)and long-term survival(P=0.289) were not statistically different between.the two groups. Conclusions Since accurate diagnosis and staginging of early ampullary cancer was diit3cult to establish perioperatively.local resection should be indicated forpoor risk pafients or those who refuse pancreaticoduedenectomy.

Triterpenoids are one of the most active constituents in Ligustri Lucidi Fructus, but only oleanolic acid has been mostly studied. In recent years, a growing number of studies have shown that other triterpenes from Ligustri Lucidi Fructus also have various biological activities, so it is necessary to build up a detailed profile of the triterpenoids in Ligustri Lucidi Fructus. The chromatographic separation was performed on a C_(18) column(4.6 mm×250 mm, 5 μm) with mobile phase of methanol-acetonitrile-0.2% formic acid for gradient elution. The detection wavelength was set at 210 nm, with a flow rate of 0.5 mL·min~(-1), and the column temperature of 25 ℃. The HPLC fingerprint of triterpenoids in Ligustri Lucidi Fructus was built by testing 21 batches of samples from different sources. The structures of the total 15 common chromatographic peaks were elucidated with UHPLC-ESI-Orbitrap-MS/MS technique and six of them were identified as tormentic acid, pomolic acid, maslinic acid, botulin, oleanolic acid and ursolic acid by comparison to the reference substances. Under the same chromatographic condition, four main triterpenes(podocarboxylic acid, hawthorn acid, oleanolic acid and ursolic acid) were quantified and the results of system adaptability and methodology investigation all met the requirements of content determination. Meanwhile, with oleanolic acid(A) as the internal reference substance, quantitative analysis of multi-components by single marker(QAMS) method was used to analyze the above four components. The relative correction factor of oleanolic acid(B), hawthorn acid(C) and ursolic acid(D) to oleanolic acid was f_(B/A)=1.12, f_(C/A)=1.02 and f_(D/A)=0.88, respectively, and the relative retention values of these three to oleanolic acid was RRV_(B/A)=0.46, RRV_(C/A)=0.70 and RRV_(D/A)=1.03, respectively. The contents determined by two methods were similar. In conclusion, the method built in this paper is proved to be simple, reliable and specific for the simultaneous qualitative and quantitative analysis of the triterpenoids in Ligustri Lucidi Fructus, which can lay foundation for further assays of the triterpenoids in Ligustri Lucidi Fructus and the relative products.

HPLC specific chromatograms of Poria were established, and the concentrations of 10 triterpenoids(16α-hydroxydehydrotrametenolic acid, poricoic acid B, dehydrotumulosic acid, poricoic acid A, polyporenic acid C, poricoic acid AM, 3-O-acetyl-16α-hydroxydehydrotrametenolic acid, dehydropachymic acid, pachymic acid, and dehydrotrametenolic acid) were simultaneously determined. Chromatographic analysis was conducted on a Welch Ultimate XB C_(18) column(4.6 mm × 250 mm,5 μm). Acetonitrile solution(contain 3% tetrahydrofuran)(A) and 0.1% formic acid aqueous solution(B) were used as the mobile phase with gradient elution at a flow rate of 1.0 mL·min~(-1). The column temperature was 30 ℃ and the injection volume was 20 μL. The experimental data were analyzed by the SPSS 22.0 and GraphPad Prism 7.0. The established triterpenoids fingerprints were specific, and the 10 components were well separated and showed good linearity(r≥0.999 6) within the concentration ranges tested. The mean recoveries were between 98.53%-103.8%(RSD 1.7%-2.7%). The method was specific and repeatable, and could be used for identification and quality evaluation of Poria. The results showed that the contents of 10 triterpenoids were positively correlated with each other. The contents of 10 triterpenoids of samples collected from producing areas were higher than that collected from markets. The total contents of 10 triterpenoids of samples collected from Hubei and Yunnan province were slightly higher than that from Anhui province, but the contents of samples from Anhui province were varied in smaller ranges.
