Objective:To investigate the changes of related indicators of right heart hypofunction in patients with primary myelofibrosis (PMF).Methods:The clinical data of 55 PMF patients in the Second People's Hospital of Lianyungang in Jiangsu Province and Jiangsu Province Hospital from January 2015 to August 2019 were retrospectively analyzed. The differences in right heart function-related echocardiographic indexes and biochemical indexes between pre-fibrosis/early stage fibrosis patients and obvious stage fibrosis patients were compared. Single factor linear regression method was used to analyze the correlations of pulmonary artery pressure with biochemical indexes.Results:The hemoglobin level [119 g/L (47-224 g/L) vs. 78 g/L (33-182 g/L)] and platelet count [233×10 12/L (5×10 12/L-984×10 12/L) vs. 117×10 12/L (7×10 12/L-731×10 12/L)] of patients in the pre-fibrosis/early stage fibrosis group were higher than those in the obvious stage fibrosis group, and the differences were statistically significant (both P<0.05). Among 22 patients with complete results of cardiac ultrasound, 90.9% (20/22) patients had increased pulmonary artery pressure, 72.7% (16/22) patients had increased left atrial diameter, and 90.9% (20/22) patients had increased right ventricular diastolic diameter. There were no patients with abnormal ejection fraction. The pulmonary artery pressure [48 mmHg (46-90 mmHg) vs. 33 mmHg (20-50 mmHg) (1 mmHg = 0.133 kPa)], left ventricular diastolic diameter [46 mm (36-50 mm) vs. 47 mm (43-53 mm)] and fractional shortening rate [38.1% (36.0%-38.9%) vs. 35.4% (32.7%-37.8%)] of patients in the pre-fibrosis/early stage fibrosis group were higher than those in the obvious stage fibrosis group, and the differences were statistically significant (all P < 0.05). The pulmonary artery pressure of patients had positive correlations with age ( r = 0.590), serum ferritin (SF) ( r = 0.608), lactate dehydrogenase (LDH) ( r = 0.711) and soluble growth-stimulating expression gene 2 (ST-2) ( r = 0.580)(all P<0.05), and had negative correlation with platelet count ( r = -0.596, P = 0.003). Conclusion:PMF patients are prone to right heart hypofunction, the pulmonary artery pressure is higher in older patients and patients with high SF, LDH and ST-2 levels and low platelet count.

Purpose:
This study aims to explore whether neoadjuvant chemotherapy with immunotherapy (NACI) leads to different tumor shrinkage patterns, based on magnetic resonance imaging (MRI), compared to neoadjuvant chemotherapy (NAC) alone in patients with triple-negative breast cancer (TNBC). Additionally, the study investigates the relationship between tumor shrinkage patterns and treatment efficacy was investigated.
Methods:
This retrospective study included patients with TNBC patients receiving NAC or NACI from January 2019 until July 2021 at our center. Pre- and post-treatment MRI results were obtained for each patient, and tumor shrinkage patterns were classified into three categories as follows: 1) concentric shrinkage (CS); 2) diffuse decrease; and 3) no change.Tumor shrinkage patterns were compared between the NAC and NACI groups, and the relevance of the patterns to treatment efficacy was assessed.
Results:
Of the 99 patients, 65 received NAC and 34 received NACI. The CS pattern was observed in 53% and 20% of patients in the NAC and NACI groups, respectively. Diffuse decrease pattern was observed in 36% and 68% of patients in the NAC and NACI groups. The association between the treatment regimens (NAC and NACI) and tumor shrinkage patterns was statistically significant (p = 0.004). The postoperative pathological complete response (pCR) rate was 45% and 82% in the NAC and NACI groups (p < 0.001), respectively. In the NACI group, 17% of patients with the CS pattern and 56% of those with the diffuse decrease pattern achieved pCR (p = 0.903). All tumor shrinkage patterns were associated with achieved a high pCR rate in the NACI group.
Conclusion
Our study demonstrates that the diffuse decrease pattern of tumor shrinkage is more common following NACI than that following NAC. Furthermore, our findings suggest that all tumor shrinkage patterns are associated with a high pCR rate in patients with TNBC treated with NACI.

Objective:To improve the cognition of T-cell large granular lymphocytic leukemia (T-LGLL) combined with pure red cell aplasia (PRCA).Methods:The clinical characteristics, peripheral blood and bone marrow laboratory indicators of 14 newly diagnosed patients with T-LGLL combined with PRCA who were admitted to the Second People's Hospital of Lianyungang Affiliated to Bengbu Medical College and the People's Hospital of Jiangsu Province from August 2010 to October 2019 were retrospectively analyzed.Results:Among the 14 patients, there were 7 males and 7 females, with a median age of 58.5 years (33-75 years). At the first visit, the median white blood cell count was 5.02×10 9/L [(1.45-8.49)×10 9/L], the median absolute value of neutrophils was 1.35×10 9/L [(0.43-7.16)×10 9/L], the median lymphocyte ratio was 0.49 (0.13-0.77), the median hemoglobin was 58 g/L (42-106 g/L), the median red blood cell count was 2.01×10 12/L [(0.99-3.20)×10 12/L], the median reticulocyte count percentage was 0.52 (0.14-3.02), the median platelet was 96×10 9/L [(38-281)×10 9/L], the median large granular lymphocytes accounted for 71% (32%-81%) of lymphocytes. Bone marrow aspiration showed that the median large granular lymphocytes accounted for 0.16 (0.08-0.41) of nuclear cells, and the median serum β 2 microglobulin was 4.85 mg/L (2.81-7.22 mg/L). Two patients had ASXL1 and TET2 mutations, and one of them had STAT3, EP300 and FAM46C mutations. Six patients were T cell receptor (TCR) β and γ-positive, 1 patient were TCRβ-positive, 4 patients were TCRγ-positive, 1 patient was TCRδ-positive, 1 patient was TCRβ, γ and δ-positive, and 1 patient was all negative. Eight cases received cyclosporine therapy, 6 cases were effective; 6 cases received methotrexate combined with hormone therapy, 3 cases were effective. The initial induction therapy was effective in 9 cases, 5 patients who failed in the initial treatment received salvage treatment, and 2 cases were effective. Conclusions:The laboratory characteristics of patients with T-LGLL combined with PRCA are similar to those of simple T-LGLL, anemia is a prominent manifestation accompanied by neutropenia or thrombocytopenia. The large granular lymphocytes are easily seen in peripheral blood and bone marrow, and T monoclonal rearrangement of lymphocytes is an important feature, and the patients respond well to immunosuppressive therapy.

Objective To analyze some related causes of hypocytosis or hematocytosis with bone marrow dry pumping. Methods Bone marrow histology, reticular fiber staining and selective immunohistochemical staining were performed in 34 bone marrow dry pumping patients with hypocytosis or hematocytosis in the Second People's Hospital of Lianyungang from January 2012 to August 2017. Results All the patients showed dizziness, fatigue, splenomegaly, night sweats and bleeding, including primary myelofibrosis (17 cases, 50.0 %), chronic myelocytic leukemia (4 cases, 11.8 %), acute myelocytic leukemia (2 cases, 5.9 %), acute lymphoblastic leukemia (1 case, 2.9 %), myelodysplastic syndrome (2 cases, 5.9 %), multiple myeloma (2 cases, 5.9 %), non-Hodgkin lymphoma with bone marrow infiltration (2 cases, 5.9 %), polycythemia vera (1 case, 2.9 %) and bone marrow metastatic tumor (3 cases, 8.8 %). The bone marrow proliferative degree in primary myelofibrosis group was mainly "grade Ⅱ" to "grade Ⅳ", and the non primary myelofibrosis group was mainly "grade Ⅲ" to "grade Ⅴ", and the differences of proliferative degree component between them were statically significant (χ2= 12.900, P= 0.004). The fibrosis level in primary myelofibrosis group was mainly "grade 2" to "grade 3", and the non primary myelofibrosis group was mainly "grade 1" to "grade 2", and the differences of myelofibrosis degree component between them were also statistically significant (χ2= 12.692, P= 0.003). Conclusions Hematological malignancies, especially primary myelofibrosis, are the common causes of bone marrow "dry pumping". Bone marrow histology, reticular fiber staining and selective immunohistochemical staining are of great significance in the etiological diagnosis.

Objective To investigate the clinical and laboratory features of IgG-2κ light chain multiple myeloma. Methods The clinical data and laboratory results of 2 multiple myeloma (MM) patients with IgG-2κ light chain were analyzed and the related literatures were reviewed. Results Two male and 1 female patients were 50-82 years old and mainly suffered with backache, infection, anemia and renal dysfunction. Multiple osteolytic bone destruction was detected in X-ray as well as magnetic resonance imaging (MRI). The level of serum IgG was normal, slight or obviously increased, but the levels of IgA and IgM were decreased. The levels of κ light chain in serum and urine were both increased significantly, and Bence-Jones protein was positive. Double M protein peaks of serum in γ area were detected by protein electrophoresis in 2 patients. A single band of IgG and double bands of light chain κ were revealed by immunofixation electrophoresis. Bone marrow smear showed that abnormal plasma cells were increased obviously. One patient gave up chemotherapy because of lung infection, acute left heart failure and acute renal failure, the others 2 patients achieved partial remission and stable disease by receiving DVD and VAD chemotherapy. Conclusions IgG-2κ light chain MM lacks typical clinical presentation, but some laboratory characteristics may be different from those of IgG-κ light chain. Further researches are needed to confirm whether or not it belongs to biclonal MM.
