KPNA2 is a member of the karyopherin family. Given its function in nucleocytoplasmic transport, KPNA2 mediates the trans-location of various proteins and is involved in numerous cellular processes, such as cellular differentiation, proliferation and apoptosis, transcriptional regulation, immune response, and viral infection. Several studies have recently demonstrated that KPNA2 is upregulat-ed in multiple malignancies. Its aberrant expression is often associated with adverse outcomes in affected patients, indicating that KP-NA2 plays a significant role in carcinogenesis and tumor progression. These findings are supported by previous studies, which reported that KPNA2 may have a functional role in the malignant transformation of cells. This study provides an overview of the research prog-ress in KPNA2 and its functional roles in multiple cancers.

Objective: Our aim was to discuss the pathological characteristics and immunophenotype of non-Hodgkin lymphoma (NHL) in Shenyang. Methods: Histopathological observation was performed with immunohistochemical methods (SP method). We used 10 antibodies as B,T markers to analyze 76 cases of NHL according to the new WHO classification. Results: The B-NHL was more prevalent than the T-NHL. In B-NHL, the Diffuse Large B cell Lymphoma (DLBL) was the most common, next was the mucosa-associated lymphoid tissue lymphoma (+/-monocytoid B-cells) and lymphoplasmacytic lymphoma (LPL). In T-NHL, the peripheral T cell lymphoma unspecificly accounted most. The positivity rates of CD79a in B-NHL were 100% and its cross-reactivity was 0. The straining rates of polyclonal CD3 with T cell were 88% and CD3 only reacted with 5% of B-NHL. Conclusion: The NHL in Shenyang was marked by the most common DLBL and peripheral T cell lymphoma, unspecificly. The rates of monocytoid lymphoma and LPL were higher. The CD79a and CD3 were antibodies of B-cell and T-cell markers with high sensitivity and specificity, respectively.

Objective:To evaluate the expression of IMP3 and CD44 proteins in recurrent urothelial carcinoma (UC) and to deter-mine the correlation between the two proteins. Methods: Data from transurethral resection of bladder (TURB) cancer cases between January 2002 and December 2012 were reviewed. Of the 54 UC recurrent cases in this study, one group of 25 had experienced recur-rence within 6 months after surgery, and the other group of 29 had their first recurrence after more than 3 years. IMP3 and CD44 immu-noreactivities were increased, which correlated with the clinicopathologic parameters. The relationship between IMP3 and CD44 pro-tein expressions was also explored. Results:Six of the 25 short-term recurrent UC cases were tested positive for IMP3 and all belonged to high-grade UC. Among the 29 long-term recurrent patients, only one case of low-grade UC tested positive for IMP3. IMP3 expres-sion rate [24%(6/25)] and intensity [weak staining at 16%(4/25) and strong staining at 8%(2/25)] were higher in the short-term recur-rent group than those in the long-term group, which had an expression rate of 3.45% (1/29) and intensity rates for weak staining at 3.45%(1/29) and without strong staining (0/29). No difference was observed in the CD44 expression between the two groups. In addi-tion, the high expression of IMP3 correlated with higher tumor stage and grade, whereas the CD44 expression tended to be inversely correlated with the tumor grade in recurrent UC patients. Furthermore, no correlation existed between the expression of IMP3 and CD44 proteins in the bladder carcinoma specimens. Conclusion:IMP3 exhibited a significantly higher expression rate in short-term re-current UC specimens than in the long-term recurrent cases. Therefore, IMP3 could be used as a novel marker, together with the other factors including tumor stage and grade, for predicting the high risk of short-term recurrence in UC patients who underwent TURB.

Purpose To explore the correlation between fetal cardiac function and interventricular septal thickness in fetuses of gestational diabetes mellitus (GDM) mothers. Materials and Methods Thirty-nine GDM mothers were involved in the study and divided into group MH (fetuses of GDM mothers with interventricular septal hypertrophy) and group NMH (fetuses of GDM mothers with normal interventricular septal thickness). Ultrasonic cardiogram was performed for both groups to assess such variables as interventricular septum thickness at end diastole (IVSd), left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), right ventricular fraction shortening (RVFS), the ratio of E and A of mitral flow (E/AMV), the ratio of E and A of tricuspid flow (E/ATV), peak velocity of aortic valve (VPAO), peak velocity of pulmonary valve (VPPA) and myocardial performance index (MPI). The results were further compared with those of control group. Results The VPAO, VPPA, LVEF and LVFS in group NMH were significantly higher than those in control group (P<0.05). The VPAO, VPPA, LVEF, LVFS and RVFS in group MH were significantly higher than those in control group whilst the E/AMV and E/ATV significantly lower than those in control group (P<0.05). The LVEF, LVFS and RVFS in group MH were significantly higher than those in group NMH whilst the E/AMV and E/ATV significantly lower (P<0.05). MPI in group MH was significantly higher than that in group NMH (P<0.05), whilst both were significantly higher than that in control group (P<0.05). The LVEF, LVFS, RVFS, VPAO and VPPA were positively correlated with IVSd (r=0.48, 0.51, 0.45, 0.30, 0.30;P<0.05). Conclusion Cardiac function in fetuses of GDM mothers may be associated with interventricular septal thickness.

Objective The study was to investigate the effect of psychological intervention on emotion and long-term effect of patients with nasopharyngeal cancer treated with radiotherapy. Methods A total of 100 patients with nasopharyngeal cancer were divided into the psychological intervention group and the control group with 50 cases in each. The patients in the psychological intervention group were given psychological intervention besides receiving radiotherapy and routine nursing which were similar to the control group. Anxiety score and depression score as well as survival rates before and after radiotherapy between two groups were compared. Results There was no difference in anxiety score and depression score between two groups before radiotherapy, but after radiotherapy, the anxiety score and depression score were more remarkably reduced in the psychological intervention group than in the control group. The 1, 3, 5-year overall survival rates were 100.0%, 94.0%, 85.9% respectively in the psychological intervention group, and were 96.0%, 85.6%, 70.7% respectively in the control group. Duration from the end of radiotherapy to relapse were (32.22±16.82) months in th psychological intervention group and (20.73±13.06) months in the control group. Conclusions Psychological intervention can improve anxiety and depression and shows a tendency to defer the occurrence of relapse and to improve the survival rate in patients with nasopharyngeal cancer treated with radiotherapy. The further research need to be done.

Objective To investigate the effects of recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF)on the gingival wound healing, and to lay a foundation for its application in the field of oral cavity.Methods 16 healthy rabbits were randomly divided into experiment and control groups(n=8).2 mm upper and lower incisors’labial gingivae were removed by scalpel. After operation, rhGM-CSF gel was applied to the surface of the wound gum in experiment group,while saline instead of drugs to the control group.2 rabbits were executed at 3,7,11,and 15 d after operation.HE staining was performed to observe the epithelium and epithelial connective tissue structure, distribution, and the changes of various cells of the rats;the number of positive epithelial cells and fibroblasts were observed by PCNA dyeing.Results On the 3rd day,the inflammatory cell infiltration was found in two groups, but a greater number of the cells were observed in experiment group;neovascularization was seen in both groups on the 7th day,and the fibroblasts and collagen fibers were observed too,but the extent of neovascularization in experiment group was more significant. On the 11th day, the fibroblasts proliferation was seen in two groups,but the extent in experiment group was more widely;on the 15th day,the trauma of gingivae of the rabbits in two groups returned to normal,there was no significant difference between two groups.Over time,the number of epithelial cells in proliferation was gradually increased,reached the peak on the 15th day.The number of fibroblasts began to increase from the 3rd day and reached the peak on the 11th day,and significantly reduced to the lowest value on the 15th day.The number of proliferative epithelial cells in experiment group was significantly higher (P<0.01)on the 3rd day and the 11th day than those in control group (P<0.01);the number of proliferative fibroblasts was significantly higher (P<0.05)on the 11th day and the 15th day than those in control group (P<0.05 ), but there were no significantly statistical differences between two groups at other time pionts(P>0.05).Conclusion RhGM-CSF can promote the infiltration of inflammatory cells, angiogenesis,proliferation of epithelial cells and fibroblasts in gingivae. RhGM-CSF is beneficial with wound healing on gum tissue.

BACKGROUND:A series of studies have found that mesenchymal stem cells play an important role in the prevention and cure of acute lung injury in adult animals.
OBJECTIVE:To further validate the effects of human umbilical cord mesenchymal stem cells on endotoxin-induced acute lung injury in newborn rats.
METHODS:Total y 120 newborn rats aged 7 days were randomly assigned to three groups. Intraperitoneal injection of 3 mg/kg endotoxin was done to establish neonatal rat model of acute lung injury in the model and stem cellgroup. Rats in the normal saline group were intraperitoneal y injected with 0.1 mL normal saline. After 30 minutes of modeling, the rats in the stem cellgroup were subjected to intraperitoneal injection of 0.1 mL human umbilical cord mesenchymal stem cells (1×106). The same volume of normal saline was administered in the normal saline and model groups. Lung tissue and blood specimens from newborn rats were taken at 6 hours, 1 day, 2 days, 4 days, and 7 days after treatment to observe lung pathological changes and detect levels of serum tumor necrosis factor-alpha and interleukin-10 as wel as myeloperoxidase activity in the lung tissue.
RESULTS AND CONCLUSION:The lung hematoxylin-eosin staining and myeloperoxidase activity indicated acute lung injury in the model group. At 4 and 7 days after modeling, the severity of lung injury in the stem cellgroup was lighter than that in the model group. Compared with the model group, the interleukin-10 level was significantly increased in the stem cellgroup, while the level of tumor necrosis factor-alpha was significantly reduced (P<0.05). These findings suggest that human umbilical cord mesenchymal stem cells transplanted into newborn rats with acute lung injury can reduce lung inflammation, and the main mechanism may be that human umbilical cord mesenchymal stem cells can balance anti-inflammatory and pro-inflammatory factors and reduce lung injury through immune regulation.
