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 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. The air fungi spores in the experiment glass slice according to their quantity were Alternaria(30.61%), Ustilaginales(23.90%), Epicoccum(18.71%), Hormodendrum(13.91%). The air fungi in the experiment container according to their quantity were Saccharomyces(50.20%), Aspergillus(12.46%), Penicillium(10.77%), Hormodendrum(9.29%) and so on. There were a lot of air fungi in the west Luzhou City all the year round. The air fungi quantity was high during May to September in a year. Conclusion A lot of fungi wave to and fro in air in the west of Luzhou City all the year round. The quantity of air fungi changes as the season goes on and it is high during May to September. The main fungi are Alternaria, Ustilaginales, Epicoccum, Hormaodendrum and so on.

Objective To study the effect of tripterygium glycosides combined with prednisone in the treat-ment of adult patients with purpura nephritis.Methods 20 adult patients with purpura nephritis were selected and randomly divided to two groups according to the random number table method.10 cases of the control group were administered with prednisone,10 cases of the observation group were administered with tripterygium glycosides and prednisone.After treatment,the treatment effect and postoperative recovery of the two groups were compared.Results The markedly effective,effective,ineffective,the total effective rates of the observation group were 5 cases(50%), 40 cases(40%),1 case (10%),9 cases (90%),respectively,which of the control group were 3 cases (30%), 4 cases(40%),3 cases(30%),7 cases(70%),there was statistically significant difference in the total effective rate between the two groups(χ2 =4.32,P <0.05);The disappeared time of negative urinary protein,hematuria,edema disappeared,negative hypertension in the observation group were (31.5 ±5.6)d,(35.6 ±6.6)d,(29.6 ±6.4)d, (30.3 ±6.5)d,respectively,which of the control group were (37.5 ±6.5)d,(42.6 ±8.2)d,(35.6 ±7.5)d, (37.7 ±7.3)d,the differences were statistically significant between the two groups(t =2.57,2.62,2.60,2.81,all P <0.05 ).The gastrointestinal discomfort,decreased white blood cells,abnormal liver function,total incidence of adverse reaction rates of the observation group were 1 case(10%),1 case(10%),1 case(10%),3 cases(30%), which of the control group were 1 case(10%),1 case(10%),0 case(0%),2 cases(20%),there was no statistically significant difference in the total incidence of adverse reaction rate between the two groups(χ2 =1.13,P <0.05).
