Objective To investigate the dangers of heart failure to the mother and fetal,and the diagnosis and treatment of pregnancy complicated with heart failure. Methods The clinical data of the causes,timing,management and outcomes of 87 cases of pregnant women complicated with heart failure from March 1993 to January 2006 were analyzed retrospectively. Results ①Thirty-one cases(35.6%) of heart failure in pregnancy were caused by rheumatic heart disease,26(29.9%) by pregnancy-induced hypertension(PIH),16(18.4%) by congenital heart disease,and 14(16.1%) by peripartum cardiomyopathy.②The heart failure appeared at the average of(32.69?5.57) weeks.③The average terminal time of pregnancy was(34.66?4.52) weeks.④There were 79 newborns with 6 cases of twins,and the perinatal mortality was 8.6%(8 cases).Hysterotomy was performed in 6 cases in mid-pregnancy.The average weight of babies was(2419.56?786.08) g.⑤The maternal mortality was 6.9%(6 cases).(Conclusion The main) causes of heart failure in pregnancy are rheumatic heart disease,PIH and congenital heart disease.Although the standard management of pregnancy complicated with heart failure is inotropic agents,diurectics and vasodilators,the treatment should be individualized according to the specific etiology and with the consideration of the safety of fetus as well.Pinpointing the causes of heart failure in pregnant patients and treating accordingly may be conducive to reduce the maternal and perinatal mortality.

Objective:To explore whether apoptotic ovarian cancer cells induced by chemotherapy drugs paclitaxel and cisplatin can be cross-presented by dendritic cells(DCs) and enhance immune responses.Methods:DCs were induced from peripheral blood monocytes cells by GM-CSF/IL-4 for 6 d,then they were stimulated with either apoptotic ovarian cancer HO8910 cells,frozen-thawed HO8910 cells or control cells for 4 h.Their surface markers and phagocytotic ability were detected by flow cytometry and confocal microscopic scanning assay,respectively.DCs of different groups were cultured with CD8+ T cells isolated by magnetic cell sorting,and the ability of DCs to activate CD8+ T cells was evaluated by 3H-TdR,the activity of CTL to kill tumor cells was evaluated by LDH.Production of IFN-? by CD8+ T cells was measured by ELISPOT.Results:Apoptotic ovarian cancer cells induced by chemotherapy drugs paclitaxel and cisplatin could be phagocytized by DCs,which subsequently promoted the maturation and antigen presenting ability of DCs.Apoptotic ovarian cancer cells implused DCs significantly promoted proliferation of CD8+ T cells compared with that of control cells(P

Objective To explore immunotherapy effective combined with active immunotherapy in different time according rats bearing-tumor after paclitaxel and carboplatin chemotherapy, and to identify the optimization time and strategy of vaccine and seek rational chemo-immunotherapy strategies in ovarian cancer treatment. Methods The dynamic immunocytes number and function in established tumor treated with paclitaxel and carboplatin chemotherapy were investigated. The changes of established tumor volume and immune function of different groups were observed according to combining different time after chemotherapy and vaccine. Results Lymphopenia was observed and the number of lymphocyte subset decreased remarkably on the 6th day, but all cells were found almost recovered on 15th day after chemotherapy. There is the process of immune-enhancing from post-chemotherapy 6 day to 10 day and reversal of immune suppression temporary. The combination post-chemotherapy 6 day with CTL caused a significantly delayed tumor growth in both tumor models and induced significant the proliferation of T lymphocyte by [H] 3 releasing. The number of CD8+T cell is the highest, but the expression of Tr cell was lowest in the group of post-chemotherapy 6 day with CTL. Furthermore, the ability of CD8+T secretion IFN-γ is the most in the post-chemotherapy 6 day with immunotherapy groups. Conclusion Combinational paclitaxel and carboplatin chemotherapy has synergistic effects with active immunotherapy boosting against tumor during window periods, where 6 days after chemotherapy with the most decreased number of lymphocytes in the animal periphery might represent the optimal checkpoint for the immune therapy against tumors. Therefore, monitoring the immune status of tumor patients might become one of the important prerequisites for the effective immune therapy when designing the comprehensive therapeutic strategies.

A highly sensitive, rapid and selective liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the quantitative determination of retinamido-ester in rat plasma was developed and validated. A simplified protein precipitation with acetonitrile was employed for the sample preparation. The separation was carried out on an Agilent TC C18 column (150 mm x 4.6 mm ID, 5 microm particle size) with the mobile phase consisted of methanol-water-formic acid (93: 7: 0.1). Simvastatin was used as internal standard. The detection was performed on a trap-quadrupole tandem mass spectrometer by selected reaction monitoring (SRM) scan mode via atmospheric pressure chemical ionization (APCI). The range of calibration curve was 0.05-50 ng x mL(-1) and the limit of quantification was 10 pg x mL(-1). The intra- and inter-day precision values were between 95.97% and 104.43%, and RSD was between 4.63% and 10.69%, respectively. This method was applied to determine the pharmacokinetic parameters. The main pharmacokinetic parameters of retinamido-ester after oral administration via gastric gavage of 2.5, 5, 10 mg x kg(-1) were as follows, T(1/2): (11.28 +/- 7.23), (8.90 +/- 3.82), (8.01 +/- 5.65) h; AUC(0-infinity): (103.41 +/- 61.46), (190.23 +/- 74.99), (421.66 +/- 229.20) ng x h x mL(-1); MRT: (6.31 +/- 0.75), (5.98 +/- 0.71), (6.18 +/- 0.97) h; CL/F: (30.10 +/- 13.67), (29.58 +/- 10.59), (31.18 +/- 17.51) L x h(-1) x kg(-1); Vd/F: (414.94 +/- 159.82), (356.16 +/- 139.85), (369.28 +/- 322.72) L x kg(-1), respectively.

PURPOSE: Choledochoduodenal fistula (CDF) is an extremely rare condition even in the most populous nations. However, diagnostic tools are inadequate for the young surgeon to be made aware of such a rare condition before surgery. Hence, basic understanding of the epidemiology, etiology, and management for this unusual but discoverable condition are necessary and essential. METHODS: The exclusive case reports of CDF, which were published from 1983 to 2014 concerning mainland Chinese people, were performed to review the epidemiology, etiology, and management. RESULTS: A total of 728 cases were incorporated into this review among 48 papers. More than half of the CDF cases were female (416) with an average age of 57.3 years. CDF was usually caused by cholelithiasis (573 of 728). Epigastric pain (589 of 728) and cholangitis (395 of 728) were the most common symptoms of CDF. CDF was usually detected and confirmed by endoscopic retrograde cholangiopancreatography (ERCP) (475 of 728) in Mainland China. The fistulas larger than 1 cm (82 of 654) were recommended for surgical biliary reconstruction. Fistulas between 0.5 cm and 1.0 cm (467 of 654) which were followed frequently by cholangitis attacks also required surgery; the rest were recommended to have stone removal and/or the application of an effective biliary drainage. Fistulas less than 0.5 cm (105 of 654) were usually received conservative therapy. CONCLUSION: CDF should be considered in differential diagnosis of recurrent epigastric pain and cholangitis. A possible ERCP should be arranged to investigate carefully. Depending on the size of fistula and clinical presentation, different programs for CDF are indicated, ranging from drug therapy to choledochojejunostomy.

OBJECTIVETo explore the prognostic factors of primary nodal diffuse large B-cell lymphomas (N-DLBCL).

METHODSAccording to the 2001 WHO classification of tumors of hematopoietic and lymphoid tissue, 51 cases of primary N-DLBCL were collected for clinical data analysis and immunohistochemical assay. Antibodies used for study were anti-CD20, CD79alpha, CD45RO, CD3, Bcl-2, Ki-67, CD30, CD15, kappa, lambda, Cyclin D1, TdT, GFAP, CK, MPO. The survival data was analyzed.

RESULTSOf the 51 cases of N-DLBCLs, 40 were reclassified as centroblastic, 3 B-immunoblastic, 1 T-cell/histiocytes rich, 2 B-cell anaplastic large cell, 1 plasmablastic, and 4 unclassified. Expression of Bcl-2 oncoprotein was observed in 24 cases (47.1%). The median Ki-67 index was 50.0% and the index more than 40% was found in 35 cases (68.6%). Survival analysis of 35 cases had follow up data showed that the 2 year and 5-year overall survival (OS) rates were 48.54% and 35.30%, respectively. The 5-year OS rates patients with International Prognosis Index (IPI) >/= 3 was lower than that with IPI < 3 (P < 0.01). The 5-year OS rates for patients with B symptoms was lower than that without B symptoms (P < 0.05). The 5-year OS rates for patients with Ki-67 index more than 40% was lower than that with less than 40% (P < 0.05). The expression of Bcl-2 oncoprotein was uncorrelated to prognosis (P > 0.05).

CONCLUSIONIPI, B symptoms and Ki-67 index are the prognostic factors for patients with N-DLBCL.
