Objective To explore the correlation of S100 protein with the prognosis of patients with primary retroperitoneal liposarcoma. Methods Analyzed the clinical data about 108 patients with primary retroperitoneal liposarcoma managed with surgery from January 2009 to June 2014. All patients were followed up. Patients were divided into S100-positive group(58 patients) and S100-negative group (50 patients) according to the immunohistochemical staining results. The overall survival time and all clinical data between two group were compared. Results All patients with primary retroperitoneal liposarcoma received radical surgical resection for the first time. The overall 5-year recurrence rate were 88.9%(96/108), and the median recurrence time was 32.7 months. The 1-year, 2-year, and 5-year recurrence rates of the S100- positive group were 25.9% (15/58), 53.4% (31/58), 96.6% (56/58), respectively, and the median recurrence time were 26.2 mouths. The 1-year, 2-year, and 5-year recurrence rates of the S100-negative group were 10.0%(5/50), 36%(18/50), 80.0%(40/50) and the median recurrence time were 40.0 mouths. Log-rank test showed that S100 protein expression was significantly associated with postoperative recurrence rates (c2=9.931, P=0.002) and survival time (c2=4.571, P = 0.033). The difference between gender, age, removal of the joint organs and tumor size showed no statistical significance on disease special survival (P>0.05). Cox regression analysis showed that S100 protein expression (OR=1.582, 95%CI:1.005-2.491) and histologic subtype (OR=1.531, 95%CI: 1.254-1.870) were independent risk factors of the prognosis of primary retroperitoneal liposarcoma patients. Conclusions S100 protein played a critical role in retroperitoneal liposarcoma carcinogenesis and its expression may be used as a potential survival predictor in patients with primary retroperitoneal liposarcoma.

Objective To study the effects of Astragalus and Thoroughfare Oral Liquid(ATOL) on the immunological functions of the immunosuppressive mice induced by hydrocortisone (HC). Methods A total of 50 mice were divided into 5 groups randomly. Mice in 4 groups were immunosuppressive animal model induced by HC, then ATOL (0.2, 0.1 and 0.05mL/10g) was administered to 3 groups of them. The phagocytotic function of peritoneal macrophage, the proliferation rate of T cells in spleen, and the cytotoxicity of NK cells in spleen, and the production of antibodies and IL-2 by spleen cells were examined to evaluate the immunological function of mice. Results Different doses of ATOL could improve the phagocytotic function of peritoneal macrophage, the proliferation rate of T cells in spleen and the cytotoxicity of NK cells. The drug could also promote antibody formation as well as IL-2 in the immunosuppressive mice. Conclusion ATOL can evidently improve some of the immunological functions in HC-induced immunosuppressive mice.

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.

AIM: To observe the effects of repeated hypoxia on the neuropeptide Y(NPY)-like immunoreactivity in the mouse brain. METHODS: Forty male kunming mice were divided into 5 groups: Control, H 1(after the 1 st hypoxic run), H 2(the 2 nd hypoxic run), H 3(the 3 rd hypoxic run)and H 4(the 4 th hypoxic run). The hypoxic groups were subjected to different runs of hypoxia exposure. The NPY-like immunoreactivity in the moue brain was measured by using radioimmunoassary method.RESULTS: The standard tolerance time of the mouse exposed to hypoxia significantly increased following each increase in runs of hypoxia exposure. After the 1 st and 2 nd hypoxic run the NPY-like immunoreactivities in the mice brain significantly increased by 145.5%?3.2% and 147.3%?2.5% compared with the control(P

The key parts of chemical fingerprinting. However, the performance of the current whole similarity determining method sometimes is inadequate when the chromatograms of different classes are similar. The present study was focused on developing a sort similarity measure determining method for these problems. In this method, chemical fingerprint features are extracted from original chromatograms for classifying the samples. Further, the fluctuations of chemical compositions among the same class samples are evaluated using an inter-class similarity measure. The proposed method was applied to evaluate the quality of Sarcandra glabra samples through their HPLC fingerprints. The results showed that the different parts of this plant, i.e., the aerial and the whole, were clearly classified, and chemical fluctuations of samples with the same sort were well represented.

Primary retroperitoneal liposarcoma is a rare low-grade malignant tumor and accounts for approximately 1% of all adult malignancies. Complete gross resection is the most important and maybe only method to cure retroperitoneal liposarcoma. The addition of advanced- modality radiotherapy to surgery for primary retroperitoneal liposarcoma is associated with improved local recurrence-free survival, and the toxic effect is tolerable. Several new drugs, especially targeted drugs, have achieved good efficacy. The aim of this article is to improve the understanding of treatment of primary retroperitoneal liposarcoma. The multidisciplinary therapy model, including surgery, radiotherapy, chemotherapy and targeted therapy, is recommended for patients with retroperitoneal liposarcoma.
