BACKGROUND:Mesenchymal stem cels can differentiate into lung parenchymal cels involved in lung injury repair, providing a new approach for the application of mesenchymal stem cels in patients with chronic obstructive pulmonary disease. OBJECTIVE:To observe the effect of bone marrow mesenchymal stem cel transplantation on the repair of airway injury in rats with chronic obstructive pulmonary disease. METHODS:Twenty-four female rats were randomized into four groups: bone marrow mesenchymal stem cel transplantation group (cel transplantation group,n=12); bone marrow mesenchymal stem cels group (cel control group,n=4); model group (n=4); healthy control group (n=4). Rat models of chronic obstructive pulmonary disease were established in the cel transplantation group and model group using fumigation+lipopolysaccharide method; and at 1 day after modeling, model rats were given 1 mL CM-Dil-labeled bone marrow mesenchymal stem cels and 1 mL PBSvia the tail vein in these two groups, respectively. In addition to tracheal injection of normal saline (300 μL) at 1 and 14 days, rats in the cel control and healthy control groups were given 1 mL CM-Dil-labeled bone marrow mesenchymal stem cels and 1 mL PBSvia the tail vein, respectively. At 1, 7, 15 and 30 days after cel transplantation, lung tissue and serum markers of al rats were detected. RESULTS AND CONCLUSION:(1) Hematoxylin-eosin staining showed that emphysema and airway injury was milder in the cel transplantation group than the model group, but severer than the cel control and healthy control groups. (2) The total number of leukocytes and neutrophils in the peripheral blood was higher in the cel transplantation group than the cel control and healthy control groups (P < 0.05); with time, the total number of leukocytes and neutrophils was decreased gradualy. (3) Compared with the cel control and healthy control groups, the interleukin-10 level in the peripheral blood was lower and the levels of tumor necrosis factor-α and granulocyte colony-stimulating factor were higher at 1 day after cel transplantation (P < 0.05). With time, in the cel transplantation group, the interleukin-10 level was increased gradualy, the level of tumor necrosis factor-α was decreased gradualy, and the level of granulocyte colony-stimulating factor was increased first and then decreased, which was highest at 7 days after cel transplantation. (4) Partial CM-Dil-positive cels were positive for CC16. Taken together, bone marrow mesenchymal stem cel transplantationvia the tail vein can improve lung injury of rats with chronic obstructive pulmonary disease, and it is involved in the repair of airway injury through differentiation into epithelial cels and immune regulation.

Background and purpose:The prognostic role of human epidermal growth factor receptor 2 (HER-2) remains controversial in patients with non-small cell lung cancer (NSCLC). This study aimed to evaluate the expression of HER-2 and its prognostic implication in patients with NSCLC.Methods:Four hundred and twenty-ifve NSCLC patients’ specimens were obtained from Zhejiang Cancer Hospital. HER-2 protein expression was determined by immunohistochemistry (IHC). The relationship between HER-2 and clinicopathological parameters and patients’ prognosis was analyzed by Chi-square test and COX proportional hazards regression model.Results:Eighty-three patients were positive expression of HER-2 (83/425, 19.5%). The expression of HER-2 was closely related with histological type (P=0.051), most patients with HER-2 positive were adenocarcinoma, then were squamous carcinoma or other histological types. However, HER-2 was not an independent prognostic indicator for the overall survival of patients with NSCLC.Conclusion:We found that the expression of HER-2 was closely connected with histological type, but it was not a predictive marker for the prognosis in patients with NSCLC.

Objective To explore the effect of hemodialysis filtration and blood perfusion in the treatment of patients with uremic encephalopathy.Methods 30 patients with uremic encephalopathy were selected,they were treated with hemodialysis filtration and blood perfusion.After the treatment,the treatment effect and postoperative recovery of patients were compared.Results In the treatment,1 case coma for 5 days,after 2 times treatment with death;1 case coma for 7 days.After 3 times the combined treatment did not restore sanity;12 patients of combined treatment after 1 time of the symptoms disappeared completely;After 3 times of treatment on the patients with residual symptoms have less.Consciousness of patients was 25 cases (83.3%).Before treatment,BUN was (28.4 ± 3.1)mmol/L,Scr was (749 ±99.6)mol/L,PTH was (245.7 ±35.2)pg/g,K + was (4.7 ±1.4)mmol/L,Na + was (137.7 ±18.4)mmol/L,Cl -was (90.8 ±16.7)mmol/L,β2 -MG was (25.4 ±3.4)mg/L.After treatment,BUN was (9.1 ±2.4)mmol/L,Scr was (199.7 ±99.2)μmol/L,PTH was (105.6 ±33.6)pg/g,K + was (4.3 ± 1.3)mmol/L,Na + was (135.7 ±14.8)mmol/L,Cl - was (85.0 ±5.2)mmol/L,β2 -MG was (13.4 ±3.1)mg/L. The differences were statistically significant (all P <0.05).Conclusion In the treatment of patients with uremic encephalopathy,hemodialysis filtration and blood perfusion have good effect,should be used in clinical promotion.

Background:In recent years,the incidence and mortality of colorectal carcinoma have been increasing rapidly. Diagnosing and treating cancer at gene level have become a new effective approach. Aims:To investigate the expression of S-phase kinase-associated protein 2(Skp2)and its relationship with vascular endothelial growth factor(VEGF)and tumor microvessel density(MVD)in colorectal carcinoma. Methods:Thirty-five colorectal carcinoma patients from March 2014 to March 2015 at People’s Hospital of Hubei University of Medicine were enrolled. Fifteen para-cancerous tissue samples were served as controls. The expressions of Skp2,VEGF and MVD value were determined by immunohistochemical SP, and their relationships with clinicopathological characteristics were analyzed. Results:The expression of Skp2 in colorectal carcinoma was significantly higher than that in para-cancerous tissue( P = 0. 000),and was correlated with tumor differentiation and lymph node metastasis(P < 0. 05),but not with gender,age and TNM stage(P > 0. 05). Expression of VEGF and MVD value were significantly higher than those in para-cancerous tissue(P = 0. 019,P = 0. 002),and were correlated with lymph node metastasis and TNM stage(P < 0. 05). Expression of Skp2 was positively correlated with the expression of VEGF and MVD value in colorectal carcinoma( r = 0. 569,P = 0. 000;r = 0. 481,P = 0. 017 ). Conclusions:The abnormal high expression of Skp2 is involved in the angiogenesis of colorectal carcinoma. Skp2,VEGF expressions and MVD value may be served as important markers for malignancy degree of colorectal carcinoma.

Objective To evaluate the effects of aerobic combined strength and balance exercise on cognitive function and satisfaction in patients with cognitive impairment no dementia. Methods Four hundred and twenty patients with cognitive impairment no dementia were divided into control group (200 cases) and experimental group (220 cases) by random digits table method. The control group received general health education and rehabilitation training. The experimental group received aerobic combined strength and balance exercise. The patients were assessed with Montreal Cognitive Assessment (MoCA) to evaluate their cognition before training, as well as after training. And the patients′satisfaction with the questionnaire was evaluated. Results The total scores of MoCA, scores of name, attention, language, memory and directionafter training were (23.47 ±2.38), (2.77 ±0.42), (5.09 ±0.86), (2.50 ±0.65), (3.42 ±0.68), (5.03 ± 0.10) points in the experimental group, and (21.20±2.55), (2.31±0.76), (4.71±1.10), (2.35±0.70), (2.23±0.81), (4.48±0.96) points in the control group, and there were significant differences, P<0.05. There were no significant differences in the space and abstract thinking between experimental group and control group:(3.61±0.91) points vs. (3.45±1.09) points, (1.83±0.76 ) points vs. (1.72±0.52) points, P>0.05. The scores of satisfaction in the experimental group was significantly higher than that in the control group:(49.33 ±1.57) points vs. ( 48.20 ±2.14) points, P<0.01. Conclusion The application of aerobic combined strength and balance exercise could improve the cognitive function and patients′satisfaction.
