ABSTRACT

Objective@#To describe the MICM (morphology, immunology, cytogenetics and molecular biology) characteristics of a case of acute myelomonocytic leukemia M 4C . @*Methods@#The medical history data of the case of M 4C admitted to our hospital was reviewed. The results of bone marrow cell morphology, cytochemical stains, bone marrow biopsy, immunophenotype, cytogenetics, molecular test and NGS (next-generation sequencing) of the case were analyzed. @*Results@#The bone marrow smear showed markedly active proliferation of bone marrow cells in which the myelomonocytic cells accounted for 85.6%. Cytochemical stains showed peroxidase (POX) stain partially and weakly positive; specific esterase AS-DCE partially positive; non-specific esterase α-NBE partially positive and smothered by sodium fluoride; non-specific esterase AS-DAE partially positive and smothered by sodium fluoride. Bone marrow biopsy showed hyperproliferative cells and diffused hyperplasia of blasts. Immunophenotype analysis showed that the abnormal cell population was positive for CD11B, CD64, CD56, cMPO, CD33, CD41, CD61, CD38 and CD58, but negative for CD13, CD34, CD117, CD7, CD123, HLA-DR, CD10, CD19, CD20, CD2, CD14, CD235, CD15, CD303, CD304, CD25, cCD79a, cCD3, cCD22, CD1a and TDT. Cytogenetic analysis showed 47, XY, t(9;11) (p22;q23),+mar. The molecular test for leukemia showed MLLT3/KMT2A gene rearrangement. NGS showed NRAS and TET2 mutation. The case was finally diagnosed as AML (acute myelomonocytic leukemia) M 4C with t(9;11)(p22;q23), MLLT3-KMT2A. @*Conclusion@#Leukemia M 4C may show the characteristics of both granulocytes and monocytes with complex morphological features. The combined examination of MICM should be necessary for the diagnosis of M 4C with great significance.

ABSTRACT

The expression or dysfunction of long non-coding RNAs (lncRNAs) is closely related to various hereditary diseases, autoimmune diseases, metabolic diseases and tumors. LncRNAs were also recently recognized as functional regulators of fibrosis, which is a secondary process in many of these diseases and a primary pathology in fibrosis diseases. We review the latest findings on lncRNAs in fibrosis diseases of the liver, myocardium, kidney, lung and peritoneum. We also discuss the potential of disease-related lncRNAs as therapeutic targets for the clinical treatment of human fibrosis diseases.

ABSTRACT

Objective To understand the anatomical features of the mine wound and provide anatomical basis for the treatment through anatomical observation of the mine wound amputation stump. Methods Three mine wound amputation stumps were dissected. The nerves, arteries and veins were separated and the length of the muscle,nerves,blood vessels and bleeding area were measured,respectively. The sec-tions of muscle tissue were observed by microscope. Results Most of the muscle tissues,nerves and blood vessels were torn and the fractures were comminuted. Observed by the microscope found that the distal muscle tissue was broken,the muscle fiber was contracted,ruptured and mortified. The muscle tissues of proximal part showed edema,most of the muscle fiber was normal and light stain,their texture was fuzzy. Conclusion The mine wound has remote effect. The shock wave of mine explosion may spread along the limbs,which leads to the tissues ruptured and hemorrhage.

ABSTRACT

Objective To investigate the expression of Delta-like 4 (DLL4) in pancreatic cancer and its clinical significance.Methods The expression of DLL4 in pancreatic cancer was examined by immunohistochemistry method.The microvessel density (MVD) was calculated after CD34 staining specifically for microvessel endothelium; and their correlations and relationship between them and clinicopathological parameters as well as prognosis of pancreatic carcinoma was investigated.Results The expression of DLL4 in pancreatic cancer was significantly higher than that in normal pancreatic tissue (68.3% vs 20%,P < 0.01).The over-expression of DLL4 in pancreatic cancer was related to degree of differentiation,TNM staging,lymph node metastasis and invasion depth,while not related to the size,location and histological types.The MVD in pancreatic cancer tissues was notably higher than that in normal tissues (34.9 ± 13.2 vs 18.9 ± 2.2,P <0.01).MVD was correlated to degree of differentiation,lymph node metastasis,but not related to the size,location and histological types.DLL4 expression was closely associated with prognosis.COX model analysis showed that TNM staging and DLL4 expression were independent prognostic factors for pancreatic cancer.Conclusions The over-expressions of DLL4 may play an important role in metastasis and invasion of pancreatic cancer.Expression of DLL4 and TNM staging is useful for predicting the prognosis of patients with pancreatic cancer.

ABSTRACT

Objective To evaluate the anatomical basis of retrohepatic tunnel used for liver hanging maneuver.Methods The anatomy of inferior vena cava ( IVC ) was studied in 20 healthy adult cadavers and 15 patients with advanced cirrhosis who underwent piggyback liver transplantation to confirm the existence of the path of retrohepatic tunnel and count the number of short hepatic veins draining into retrohepatic IVC.Results Short hepatic veins mainly drain into the IVC on its left and right sides.The number of short hepatic veins that drain into the upper or middle portion of the IVC was significantly more than that into the lower portion ( x2 =48.524,P < 0.01 ).On the path of retrohepatic tunnel,most short hepatic veins that drain into the IVC are located on the front side ( F =9.188,P < 0.01 ).There was no significant difference in the number of short hepatic vein between the groups of liver cirrhosis and that of healthy adults ( t =0.405,P > 0.05 ),but anatomic variation of post-hepatic tunnel is common in liver cirrhotics.Conclusions Retrohepatic tunnel was a potential space and had a unique anatomical feature.The establishment of retrohepatic tunnel by liver hanging maneuver is safe in noncirrhotics.However,in advanced posthepatitic cirrhosis,retrohepatic tunnel should be used with caution.
