Objective: To study the regulatory effects of antifibrotic cytokines, interleukin 10 (IL-10), hepatocyte growth factor (HGF), and interferon-gamma (IFN-γ) on activity of TGF-β1 gene promoter, so as to assess the antifibrotic mechanism of cytokines. Methods: Sequence - 1328-+812 of TGF-β1 gene, which contains the - 509 C>T polymorphism, was selected as putative promoter. The recombinant constructions containing - 1328-+ 812 of TGF-β1 gene and CAT reporter gene (phTGF2. 14T, phTGF2. 14C) were constructed and transfected into HepG2 cells with liposomal transfection method, then the transfected HepG2 cells were treated with IL-10(4 ng/ml), HGF(10 ng/ml) or IFN-γ(20 ng/ml). Reporter gene activity was analyzed by ELISA. Results: Reporter gene activity in cells transfected with phTGF2. 14C was significantly higher than those transfected with phTGF2. 14T (P<0.01). IFN-γ significantly inhibited the reporter gene activity in HepG2 cells transfected with phTGF2. 14C or phTGF2. 14T(P<0.05); HGF significantly increased the reporter gene activity in cells transfected with phTGF2. 14C (P<0.05). IL-10 had no effects on the activities of cells transfected with phTGF2. 14C or phTGF2.14T. Conclusion: C allele at - 509 can increase the promoter activity of TGF-β1 gene in HepG2 cells. The antifibrotic effect of IFN-γ might be related to its inhibitory effect on the putative promoter activity of TGF-β 1 gene; the antifibrotic effects of HGF and IL-10 may not be through regulation of TGF-beta1 gene transcription.

Objective The research was to achieve Shanghai resident satisfaction of primary health service after new health reform.Methods During self-compiled questionnaire survey,the research adapted stratified random sampling to select 9 community health centers in Shanghai urban,rural and suburb areas.Results Shanghai resident satisfaction rate of new health reform was 85.2％.Satisfaction rate of basic medical security system was 85.0％.Satisfaction rate of basic medical service was 96.5％.Satisfaction rate of basic public health service was 95.1％.Age,region,job,education and income were main factors to satisfaction of primary health service.Conclusion From an overall point of view,Shanghai resident satisfaction of primary health service after new health reform was high.However,the level of basic medical security and convenience of reimbursement were not high.Medical expenses of primary health care institution had not been effectively controlled.Basic medicine could not fully meet the medication needs of primary health care institutions.

AIM: To investigate the variation and significance of mRNA and protein concentration of myeloid cell leukemin-1 (Mcl-1) in apoptotic HepG2 cells induced by apoptin. METHODS: The apoptin expression vector pCDNA3.0-VP3 was transfected into HepG2 cells via liposome. Mcl-1 mRNA was analyzed by real-time quantitative reverse transcriptase-polymerase chain reaction. The protein of apoptin, Mcl-1 and cytochrome C were detected by Western blotting. RESULTS: The VP3 gene was transfected into HepG2 cells successfully and expressed steadily. Compared to blank control, Mcl-1 mRNA and protein levels of VP3 positive cells were decreased (mRNA: 0.09%±0.00% vs 0.41%±0.14%, P<0.05; protein: 0.43%±0.01% vs 0.90%±0.04%, P<0.01). Released cytochrome C from mitochondrion was increased (0.98%±0.02% vs 0.62%±0.03%, P<0.01). CONCLUSION: In the course of the apoptosis of HepG2 cells induced by apoptin, the amount of Mcl-1 mRNA and protein is decreased, and released cytochrome C from mitochondrion is increased. The apoptosis induced by apoptin may be correlated with the down-regulation of Mcl-1 mRNA and protein.

Objective To discuss the diet balance by the enteral nutritional support for patients after hematopoietic stem cell transplantation. Methods We divided 47 patients after hematopoietic stem cell transplantation into the balanced-diet group and the ordinary-diet group. The balanced-diet group received diet according to "diet exchange share" method and took food by the proportional share of 5 kinds of food. The ordinary-diet group took food according to the habits of patients.The effect of nutritional support was compared between the two groups. Results The body weight,white blood cell,hemoglobulin,platelet,total protein and proprotein in the balanced-diet group at the 90th day were different from those at the 30th day after transplantation(t value were -8.5,-4.7,-4.2,-10.2,-3.9,-14.1 and -80.9),P ＜ 0.01.In the ordinary-diet group only body weight,platelet and proprotein at the 90th were statistically different from those at the 30th day after transplantation (t value were -4.5,-4.6 and -14.9), P ＜ 0.01. Conclusion Balanced diet contributed to the rehabilitation and nutritional support after hematopoietic stem cell transplantation.

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.

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.
