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.

Diagnostic coincidence and pendency are important statistical indexes in hospital administration,they come from hospital statistical program in hospital information system.The article discusses diagnostic coincidence and pendency in hospital information system,points out the program's fatal vices and puts forward relevant method.

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 investigate the effect of selenium(Se) and vitamin E(VE) on collagen Ⅰ synthesis in cultured cardiac fibroblasts(CFbs) treated with norepinephrine(NE).Methods CFbs were obtained by the method of enzymatic digestion culture.Cells and culture medium were collected after 48 h,then the hydroxyproline(HYP) and collagen Ⅰ content as well as the expression of ?_1 col1agen mRNA were examined.Results The contents of HYP in Se,VE and Se+VE groups were(64.88?1.25),(47.60?1.59) and(41.34?(1.73) mg?L~(-1)) prot,respectively,all of them were lower than that in NE group(P

Considering technology,regulations and other factors,nowadays we still use the records of print instead of in digital.《Electric Signature Law》makes a new environments for the study of electric medical records system.It regulates the writing,originally form and the save of electric medical records,affirms its value of evidence in court and prescribes what is dependable electric signature.

Objective: To explore the clinical value of transvaginal ultrasonography in diagnosis of ruptured ovarian cyst. Methods:Retrospective analysis the 46 cases of ruptured ovarian cyst diagnosis by transvginal ultrasonography in our hospital which confirmed by surgery and pathology. Results: In the among 46 cases, 39 cases were the corpus luteum cyst, 14 cases were the endometriotic cyst, were all confirmed by surgery and pathology, the diagnostic accurate rate of corpus luteum cyst is 92.3%, the rate of endometriotic cyst is 57.1%. Conclusion:Transvaginal ultrasonography is accurate, rapid and convenient, provides the reliable basis for the diagnose and different diagnose acute abdominal disease.

Objective:To explore the relationship of perfection of middle school students and parental rearing behavior.Methods:392 middle school students were investigated by FM PS and CFMPS.Results:①There was a significant difference in OR between different gender(t=-3.039,P

OBJECTIVE:To provide references for drug administrator in coping with the challenge of drug shortage and the promotion of rational drug use. METHODS: With American Society of Hospital Pharmacists Guidelines on Managing Drug Shortages as references,the feasible management strategies for drug shortage in China were put forward based on the reality of our country and our experience in the practice of drug shortage management. RESULTS & CONCLUSIONS: It is advisable to draw experiences from U.S. Food and Drug Administration to tackle the problem of the shortage of essential drugs through the co-efforts of Ministry of Public Health,State Food and Drug Administration and Stage Development and Reform Committee and develop contingency planning strategy in health care organization to deal with the shortages of certain drugs and reduce potential clinical safety hazard induced by drug shortages.

Objective To investigate the sorts and quantities of air fungi in air and its change in every month in the west of Luzhou City. Methods The experiment glass slice was exposed every day and the experiment container was exposed every month in one year so as to investigate air fungi in Luzhou Library Building in the west of Luzhou City. The fungi were separated and cultured, the specimens of fungi were pressed on glass slice timely, dyed with methyl blue and identified. Results 365 experiment glass slices were exposed every day in one year. 24 139 fungi spores were checked and 23 582 were identified. They belonged to 24 species.
