Objectives To investigate peripheral cytopenia in patients with splenomegaly due to hepatitis B-related cirrhotic portal hypertension (HBRCPH) by comparing blood cell counts from enlarged spleens with peripheral blood. Methods This prospective study involved patients undergoing splenectomy at the Nangfang Hospital from June 2013 to December 2015. Blood cell counts from peripheral blood were compared with those from splenic blood taken during splenectomies. Results Clinical data were available from 30 patients. White blood cell (WBC), red blood cell (RBC) and platelet counts were statistically significantly lower in peripheral blood compared with splenic blood. After splenectomy, peripheral blood cell counts increased significantly compared with pre-operative levels. Platelet and WBC counts in the lower spleen were significantly higher than those in the porta lienis (middle segment) and upper spleen. Conclusions In patients with splenomegaly due to HBRCPH, the counts of three blood cell lineages were significantly higher in the spleen than in peripheral blood. Splenectomy can aid the return of peripheral blood cell counts to normal levels. The most significant retention of platelets and WBCs occurred in the lower spleen which may be useful information for surgeons performing partial splenectomies.

Objective: To summarize and investigate the characteristics, prognosis and treatments of chronic lymphocytic leukemia (CLL) patients with trisomy 12 by using FISH (CEP12). Methods: Clinical data of 330 CLL patients were analyzed retrospectively by using FISH (CEP12) to detect trisomy 12 from May 2003 to April 2015. The clinical data and laboratory characteristics of CEP12 positive patients (70 cases) were compared with those CEP12 negative patients (260 cases). Results: Compared with CEP12 negative CLL patients, the proportion of hepatomegaly (13.6% vs 4.0%, P=0.011) and LDH>247 U/L (43.3% vs 18.5%, χ(2)=15.892, P<0.001) in CEP12 positive CLL patients were much higher, respectively. There were no significant differences between age, sex, clinical stage, β(2)-microglobulin level, IGHV mutation ratio and splenomegaly/lymphadenopathy in these two subgroups. However, compared with CEP12 negative patients, CEP12 positive patients had higher ratio of FMC7 (23.8% vs 12.7%, χ(2)=4.730, P=0.030), and lower ratio of CD23 (95.2% vs 99.6%, P=0.033). The overall response rates (ORR) in Fludarabine (without Rituximab), Rituximab (with or without Fludarabine) and the traditional chemotherapy group (chlorambucil, CHOP or CHOP-like) were 77.5% (31/40), 84.8% (56/66) and 45.4% (50/110), respectively. The ORR of the traditional chemotherapy group was lower than that of the Fludarabine group and Rituximab group. For CEP12 positive patients, the ORR was inferior to CEP12 negative patients when only using Fludarabine (P<0.05). However, when using Rituximab, the difference could be eliminated, and the ORR was even a little higher in CEP12 negative patients (91.7% vs 81.0%, P=0.306). Compared with CEP12 negative patients, there were no significant differences in progression-free survival (PFS) (χ(2)=0.410, P=0.478) and overall survival (OS) (χ(2)=0.052, P=0.180) for CEP12 positive patients whom the median time from diagnosis to start treatment and OS time was 22.6 (95%CI 15.4-31.7) and 118.5 (95%CI 74.5-162.4) month while the 5-year PFS and OS were (52.9±7.6)% and (74.8±6.6)%. Conclusions: CEP12 positive CLL patients are more common in hepatomegaly and higher level of LDH. The traditional chemotherapy treatment had the lowest efficacy, and the curative effect of single use of fludarabine is not as good as that of CEP12 negative patients, however, when using Ritaximab, the efficacy could be comparable.

Objective: To determine the valuable hemolytic characteristics in differential diagnosis of paroxysmal nocturnal hemoglobinuria (PNH), autoimmune hemolytic anemia (AIHA) and hereditary spherocytosis (HS). Method: The clinical and hemolytic characteristics of 108 PNH patients, 127 AIHA patients and 172 HS patients diagnosed from January 1998 to April 2017 were compared. Results: ①Reticulocyte percentage (Ret%) of PNH patients [6.70% (0.14%-22.82%)] was significantly lower than that of AIHA [14.00%(0.10%-55.95%), P<0.001] and HS patients [11.83%(0.60%-57.39%), P<0.001]. The Ret% in PNH patients were significantly lower than those in AIHA and HS patients at the same levels of anemia, except for in mild anemia between PNH and AIHA patients. However, when comparing the Ret% between AIHA and HS patients, there was significant difference only in mild anemia [7.63%(1.87%-29.20%)% vs 11.20%(3.31%-22.44%), z=-2.165, P=0.030]. ②The level of TBIL in HS patients was significantly higher than that in AIHA and PNH patients [79.3 (11.2-244.0) μmol/L vs 57.6 (7.6-265.0) μmol/L, z=5.469, P<0.001; 79.3(11.2-244.0) μmol/L vs 26.2(4.6-217.7) μmol/L, z=-2.165, P<0.001], and the proportion of HS patients with TBIL more than 4 times the upper limit of normal (ULN) (64.1%) was significantly higher than that of AIHA (37.7%, χ(2)=19.896, P<0.001) and PNH patients (4.6%, P<0.001). ③The LDH level of PNH patients was significantly higher than that of AIHA and HS [1 500 (216-5 144) U/L vs 487 (29-3 516) U/L, z=-9.556, P<0.001; 1 500 (216-5 144) U/L vs 252 (132-663) U/L, z=-11.518, P<0.001], and the proportion of PNH patients with LDH more than 1 000 U/L (79.1%) was significantly higher than that of AIHA patients (13.0%, χ(2)=93.748, P<0.001) and HS patients (0, P<0.001). ④Splenomegaly occurred in 43.5% of PNH patients, including 16.0% with severe splenomegaly. In contrast, the occurrence of splenomegaly was 98.6% in AIHA patients and 100.0% in HS patients (P<0.001), and 63.0% of AIHA patients (P<0.001) and 90.4% of HS patients (P<0.001) were with severe splenomegaly. ⑤The prevalence of cholelithiasis in HS patients was up to 43.1%, significantly higher than that in AIHA patients (10.5%, P<0.001) and PNH patients (2.9%, P<0.001). Conclusion: The comprehensive assessment of the five hemolytic characteristics is simplified, practical and efficient, with great clinical significance, providing specific indicators for differential diagnosis and efficient approach for making further work-up.

- CONCLUSIONS: Using FcγRIIB232T/T mice we provide evidence for a critical role of FcγRIIB/c-Abl in the negative selection of GC B cells. Importantly, our findings implicate potential benefits to up-regulate FcγRIIB expression in B cells for SLE treatment. This article is protected by copyright. All rights reserved.
- Spleen and splenic vascular involvement in acute pancreatitis: an MRI study. [Journal Article]
- QIQuant Imaging Med Surg 2018; 8(3):291-300
- CONCLUSIONS: Splenic vascular involvement and splenomegaly were common in AP. The vascular involvement was associated with the severity of AP. This complication should be considered when severity and prognosis of AP are assessed. Quantitative analysis of the spleen with IVIM might be a useful imaging biomarker for splenic perfusion changes in AP, especially in those with splenomegaly.

Systemic isosporosis, also called atoxoplasmosis or visceral coccidiosis, is a disease that affects birds in general. Pathogenesis of systemic isosporosis and its etiologic agent have not been well characterized, but taxonomically Atoxoplasma is currently considered a junior objective synonym of Isospora. The present report aimed to describe pathological and molecular findings of systemic isosporosis in captive green-winged saltators (Saltator similis) from the State of Espírito Santo, Brazil. In a commercial breeding facility eleven birds with two to nine months of age died from 2015 to 2016. These birds developed nonspecific clinical signs, including bristly feathers, hyporexia, loss of weight, and apathy. Two birds were necropsied, and grossly there were hepatomegaly, splenomegaly, necrosis of lymphoid follicles, hepatic necrosis, and severe enteritis. Merozoites were observed in the heart, small intestine, proventriculus, brain, liver, spleen, and kidneys. 23 S RNA PCR amplicons from DNA extracted from the liver and the intestinal contents had 99% identity with Atoxoplasma sp., whereas amplicons of mitochondrial cytochrome c oxidase subunit 1 ha d 97% identity with Isospora greineri. In conclusion, this report indicates that systemic isosporosis in green-winged saltator is a disease that affects the spleen, liver, and small intestine, with high mortality for young birds, resulting in significant loses to commercial breeding facilities.
