Objective To analyze the multi-slices spiral CT (MSCT) findings of hepatic alveolar echinococcosis(HAE), and to evaluate the value of MSCT for diagnosis of HAE. Methods Twenty-six cases with HAE were scanning by MSCT. The raw data were transmitted to advanced workstation for reconstruction imaging. Correlated studies were made between the CT features and pathology or other imaging results. Results Altogether 28 lesions were detected. They all revealed as heterogeneous hypodense mass with ill-defined boundary in plain CT but were easily being distinguished from surrounding parenchyma after contrast medium injection.Characteristics of the lesions include different amount of calcification (26/26), liquefied necrosis in center area (20/26), peripheral lacunae or alveolar signs (15/26), compensatory hypertrophy of healthy hepatic part (18/26) and the retraction in the involved hepatic lobe or segment (12/26). The lesions that located at or extended to hepatic hilum caused dilatation of intra-hepatic biliary ducts(9/26), splenomegaly (12/26), and ascites (1/26). MSCT angiography (CTA) depicted signs of abnormalities of hepatic vessels such as compression, displacement, encasement and occlusion. Compared with findings of operation, the sensitivity, specificity and positive prediction value of CTA for evaluating the hepatic artery system disorders were 88%, 96% and 93%, respectively; and for portal venous system were 95%, 100% and 95%, respectively; while for hepatic venous system were 96%, 86% and 96%, respectively. Conclusion MSCT is able to comprehensive display the CT features and vessels complication of HAE. It provides reliable imaging for both accuracy diagnosis and proper treatment of the disease.

The study was aimed to explore clinical result of cyclosporin A (CsA) and androgens for treatment of myelodysplastic syndrome (MDS) with refractory anemia. Four cases of MDS-RA were treated with CsA and androgens, while the changes of blood counts, bone marrow and chromosome were observed. The results showed that substantial hematological response was observed in all four patients, that their anemia improved and all transfusion-dependent patients achieved transfusion independence. In conclusion, CsA and Adr therapy was well tolerated. CsA and Adr therapy offer an alternative treatment of MDS with RA. The mechanisms of the benifical effect from this therapy remain the subject of an ongoing study.

Objective:To evaluate the relationship between hemoglobin(Hb) level and the risk of diabetic retinopathy(DR) in patients with type 2 diabetes mellitus(T2DM).Methods:This study was a prospective cohort study. A total of 1 730 T2DM patients without DR, who received regular management at the Li′s Clinic in Taiwan, China starting from 2002, were selected as the study population. All patients underwent annual dilated fundus examination by professional ophthalmologists. General patient information and laboratory results were collected and analyzed. Based on the occurrence of DR during patient follow-up, patients were divided into the DR group and the non-DR(NDR) group. The impact of Hb levels on DR was explored using a generalized linear mixed model, and the relationship between Hb levels and DR was studied using Cox proportional hazards regression model.Results:After an average follow-up of 9.79 years, 481 patients with DR were detected. Compared with NDR group, DR group displayed a longer course of diabetes, higher rates of cataract, insulin use, and anemia, and higher systolic blood pressure, HbA 1C, and UACR as well as lower Hb. The results of the generalized linear mixed model showed a negative correlation between Hb and the occurrence of DR( β=-0.015, P<0.001). The Cox proportional hazards regression model showed that, after adjusting for confounding variables and based on quartiles of average Hb levels during follow-up, the risk of developing DR increased by 56.9% in the Q1 group(Hb≤127 g/L) compared to the Q4 group(Hb≥142 g/L). The cumulative risk plot showed that, after adjusting for confounding variables, the Q1 group had the highest cumulative risk of developing DR, and the difference was statistically significant( P<0.05). Conclusion:Hb was negatively correlated with DR, and the lower Hb levels were associated with the occurrence of DR, independent of other influencing factors.

Objective of this study was to evaluate the efficacy and safety of haploidentical or unrelated donor hematopoietic stem cell transplantation (HSCT) for patients with severe aplastic anemia (SAA). Twenty patients with SAA received allogeneic HSCT from haploidentical or unrelated donors (14 from haploidentical donors and 6 from unrelated donors) from November 2005 to May 2011. Conditioning regimen consisted of fludarabine (FLU), cyclophosphamide (Cy) and anti-thymocyte immunoglobulin (ATG). The patients were administrated with G-CSF-primed bone marrow and mobilized peripheral blood as grafts from haploidentical donor or only mobilized peripheral blood from the unrelated donor. The results showed that the median time of neutrophil and platelet engraftment were 14 (11 - 20) d and 17 (13 - 31) d respectively. All patients who achieved engraftment had complete hematologic recovery with complete donor chimerism, except for two patients who developed graft failure in 2 months after transplantation. Four cases developed acute grade IIGVHD. The chronic GVHD occurred in 7 of the 16 evaluable cases (6 limited, 1 extensive). 14 patients got disease-free survival with follow-up to January 2012. The disease-free survival rate was 68.9%. It is concluded that the haploidentical or unrelated donor hematopoietic stem cell transplantation may become a viable therapeutic option for severe aplastic anemia patients who lack suitable human leukocyte antigen-matched donors and fail immunosuppressive therapy.

This study was purposed to explore the efficacy and feasibility of reduced-intensity allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of multiple myeloma (MM). Three patients with MM from January 2011 to January 2012 in General Hospital of Beijing Military Area were treated by reduced-intensity allo-HSCT. All donors are compatriots and affinity HLA identical. Donors were mobilized with granulocyte colony-stimulating factor (G-CSF), the MM patients were given combined transplantation of bone marrow and peripheral blood stem cells. Preconditioning regimen consisted of fludarabine combined with melphalan and anti-human thymocyte globulin, and the classic cyclosporin A (CsA) combined with methotrexate (MTX) was used to prevent graft-versus-host disease (GVHD). The preventive donor peripheral blood stem cell infusion in dose 0.2×10(8)/kg mononuclear cells (MNC) was applied after 3 months of transplantation, then the toxicity, GVHD and disease-free survival (DFS) in patients were observed after transplantation. The results showed that 3 patients got hematopoietic reconstitution, the average time of neutrophils ≥ 0.5×10(9)/L and platelets ≥ 20×10(9)/L was 14.3 d and 15.3 d respectively, the detection of implanting efficacy displayed 100% complete donor hematopoiesis. Follow-up to January 2013, the median follow-up time was 13 months (12 to 15 months), As a result, none of the patients got GVHD, infection and other serious complications, all patients are still in complete remission (CR), the longest DFS time has reached to 15 months. It is concluded that the reduced-intensity allogeneic hematopoietic stem cell transplantation is the effective method for MM, this method has the high safety and efficacy, as well as high complete remission rate in early transplantation, the MM patients may get a long-term survival. This method can be used as a key technology in clinic for treating MM.

{L-End}Objective To analyze the effects of night shift work and overweight/obesity on blood pressure of workers in chemical fiber industry. {L-End}Methods A total of 1 004 workers of a chemical fiber factory were selected as the study subjects using convenient sampling method, and their blood pressure and body mass index were measured. Multiple linear regression model was used to analyze the relationship between night shift work and blood pressure, and multiple logistic regression was used to assess the independent impact and combined impact of night shifts and overweight/obesity on the risk of hypertension. {L-End}Results Compared with the non-night shift workers, the prevalence of hypertension in night shift workers was increased (5.3% vs 13.0%, P<0.05), with elevated systolic and diastolic blood pressure (both P<0.05). The results of multiple linear regression analysis showed that the systolic blood pressure and diastolic blood pressure of the night shift workers were higher than those of the non-night shift workers (both P<0.05), and the systolic blood pressure and diastolic blood pressure of overweight/obesity workers were higher than those of non-overweight/obesity workers (both P<0.01). The results of multiple logistic regression analysis showed that the risk of hypertension in night shift workers and overweight/obesity workers was higher than that in non-night shift workers and non-overweight/obesity workers [odds ratio (OR) and 95% confidence interval (CI) were 2.49 (1.04-5.99) and 2.65 (1.77-3.95), both P<0.05]. Night shift work and overweight/obesity showed a synergistic effect on blood pressure of workers. Compared to non-overweight/obesity non-night shift workers, overweight/obesity night shift workers had a higher risk of hypertension (OR=4.93, 95%CI: 1.70-14.29, P<0.01). {L-End}Conclusion Night shift work could lead to elevated blood pressure in workers in the chemical fiber industry, which is a potential risk factor for hypertension. The synergistic effect of night shift work and overweight/obesity may contribute to the increased risk of hypertension.
