Objective To explore and clarify the clinical features and management of patients with Castleman disease.Methods The clinicopathological features and therapeutic method of 65 patients with Castleman disease admitted to our hospital continuously from 2005 to 2012 were analyzed retrospectively.The mean follow-up time for the entire series was 40 (15-71) months.Results In contrast to Localized Castleman disease(LCD),Multicentric Castleman disease (MCD) patients were relatively older and exhibit various symptoms and abnormal laboratory tests.We found 44 tumor in LCD group.LCD ones,most of which were hyaline vascular (33/42,78.6％),were more likely originated in retroperitoneum,enterocoelia(10/44,22.7％) or mediastinum(10/44,22.7％).The initial treatment for LCD patients was complete surgical resection and all patients are current alive with no evidence of recurrence.MCD ones always accompanied by fever(9/23,39.1％),anemia(9/23,39.1％)and splenomegaly,and most of MCD patients were plasmacytic variants(14/23,60.9％) or mixed cellular variants (5/23,21.7％).We found 66 tumor in MCD group and they were more likely originated in neck (16/66,24.2％) and groin area (12/66,18.2％).Surgery combined with CHOP-like chemotherapy or CHOP-like chemotherapy alone was the mainstream treatment for MCD ones.21 patients achieved complete remission or partial remission,and only 2 patients died of lung infection.Whether patients could tolerate long-term chemotherapy or not was an important prognostic factor.Conclusions LCD patients had no typical clinical symptoms and could be cured by surgery.Most of MCD patients always had a good prognosis after receiving CHOP-like chemotherapy.

This study was designed to use iTRAQ technology coupled with 2D LC-MS/MS to study the comparative proteomics of different processing technology for pilose antler. 1015 proteins were identified with 2D LC combined with MOLDI TOF/TOF mass spectrometry. Comparative analysis with Protein Pilot (Version 4.5) revealed that 87 proteins were changed (P ≤ 0.05, the ratio of > 1.50 or < 0.60 as the threshold selection of difference proteins), of which 24 were up regulated and 33 were down regulated in the traditional frying process (TFP) compared with the fresh pilose antler (P ≤ 0.05). 7 significant different proteins (P ≤ 0.001), most of these significantly changed proteins were found to be involved in calcium ion binding and ATP binding associated with human healthy. Freeze drying with protective agent (FDP) (Trehalose) can improve the content of significantly different proteins (P ≤ 0.001) including Collagen alpha-1 (XII) chain (COL12A1) and Collagen alpha-1 (II) chain (COL2A1). The significant function involves in platelets activating, maintenance of spermatogonium, and disorder expression in tumor cells. The functional annotation by Hierarchical clustering and GO (gene ontology) showed that the main molecule functions of the proteins significantly changed in these processes were involved in binding (52.7%), catalytic (25.3%), structural molecule and transporter (6.6%).

Objective This paper was to study the absorption and metabolism differences of intestine and liver for multicomponent licorice.Methods The components were identified with the UPLC-MS/MS. In situ closed-loop method was used to carry out the comparative experiments of absorption and metabolism differences between intestine and liver.Results 13 components were identified by UPLC-MS/MS. The absorption and metabolism results indicated some components in licorice water extract could be absorbed into blood and metabolism happened during this process. 14 metabolites were detected in the plasma sample. The hepatic metabolism results indicated many components could experience complex metabolism and more metabolites could be generated.Conclusions Liver was the major metabolism organ for licorice water extract and some components could be metabolized along with the absorption process in intestine. The absorption and metabolism differences between intestine and liver were significant.

ObjectiveComparingfourgroupsofimmunosuppressivemousemodelsestablishedby cyclophosphamide administration in different doses and periods , we used partial least squares ( PLS) analysis to evaluate the immunosuppressive mouse models comprehensively and select the appropriate way to establish this model .Methods In this experimental study, 58 male KM mice were randomly divided into five groups: normal group (10 mice) were given normal saline daily by i.p.injection, model group 1 (12 mice) was given 40 mg/kg CTX daily by i.p.injection for 10 days, model group 2 (12 mice) was given 80 mg/kg CTX daily by i.p.injection for 3 days, model group 3 (12 mice) was given 40 mg/kg CTX daily by i.p.injection twice for a week, model group 4 (12 mice) was given 50 mg/kg CTX daily by i.p.injection for 7 days.After the injection of cyclophosphamide , the daily metabolic activities were detected everyday such as body weight , water intake , and food intake , organ index and immunological indexes such as blood RT of the model mice were measured as well .Using partial least squares ( PLS) analysis to the models and analyzing the final weight , final anal temperature , organ index , and blood routine examination in order to evaluate the immunosuppressive mouse models comprehensively .Results Compared with the normal group , different dosages of CTX reduced the weight and anal temperature of model mice (P<0.05), the food intake and water intake (P<0.01), and the spleen index and thymus index ( P<0.01 ) .Besides , the amount and percentage of basophilic granulocytes decreased ( P <0.05 ) , and the percentage of MCHC , macrophage went up , as well as the absolute value of WBC and lymphocytes were decreased in the model groups 1, 2, and 4 (P<0.05).According to the PLS analysis, there were significant differences among models 1, 2, and 4 when compared with the normal group , especially the most different in the model group 1.Conclusions After the PLS analysis of different indexes , the optimal way to establish immunosuppressive mouse models is the procedure with 40 mg/kg CTX daily injected i .p.for ten days .Our findings provide experimental evidence for the establishment of immunosuppressive mouse models .

This study was aimed to determine the solubility an d oil-water partition coefficient of main active com-ponents in Ge-Gen Qin-Lian (GGQL) Tablets (puerarin, baicalin and berberine hydrochloride) in phosphate buffer solution of different pH values and under the background of many components. Solubility of puerarin, baicalin and berberine hydrochloride in different medium pH, and oil-water partition coefficient of the octanol-water and oc-tanol-buffer system were determined by HPLC method. The results showed that the solubility and oil-water partition coefficient of puerarin, baicalin and berberine hydrochloride were varied with the change of pH, and varied under the background of components. At pH 7.4, the solubility was the biggest;puerarin was 7.56 mg·mL-1;baicalin was 17.07 mg·mL-1; berberine hydrochloride was 3.57 mg·mL-1. Oil-water partition coefficient P of these components at pH 1.0 was bigger;puerarin was 0.420 (lgP=-0.38);baicalin was 10.783 (lgP=1.03);berberine hydrochloride was 0.267 (lgP=-0.57). It was concluded that lipid solubility of puerarin, baicalin and berberine hydrochloride at pH 1.0 was better. It was speculated that better absorption in the stomach, and low lipid solubility under other pH. It was speculated that lipid solubility may be one of the reasons affecting the intestinal absorption.

Objective: To investigate the expression and prognostic value of alpha smooth muscle actin(α-SMA) and Ki-67 in retroperitoneal leiomyosarcoma. Methods: Fifty retroperitoneal leiomyosarcoma patients who underwent operation in Chinese People′s Liberation Army General Hospital from May 2002 to December 2015 were retrospectively analyzed. There were 14 males and 36 females form 21 to 79 and an average age of 48. Kaplan-Meier estimations and Cox regression analyses were performed. Results: Of the 50 cases, 45 patients underwent complete resection, and others are not. The overall 1, 3, 5-year survival rates were 86.0%, 46.0% and 28.0%, respectively. Tumor size, extent of resection, pathological stage, and expression levels of Ki-67 and alpha smooth muscle actin (α-SMA) were closely related to the survival of retroperitoneal leiomyosarcoma patients (all P<0.05), respectively. Multivariate analysis showed that pathological grade and degree of surgical resection were independent risk factors in the prognosis of patients (P<0.05). Conclusion The high expression of α-SMA and Ki-67 are indicators of poor prognosis in retroperitoneal leiomyosarcoma, which can be used as a potential survival predictor in patients with retroperitoneal leiomyosarcoma.
