Objective To explore the application of bilevel non-invasive mechanical ventilation in the treatment of chronic obstructive pulmonary disease(COPD) with respiratory failure.Methods 126 COPD patients with type Ⅱ respiratory failure were selected and divided into control group and research group,63 cases in each group.The control group received regular treatment,and the research group received bilevel non-invasive mechanical ventilation on the basis of regular treatment.,The results of blood gas analysis,respiratory frequency(RR),heart rate(HR) and expiratory flow(PEF) were observed and compared between the two groups.Results The indicators of pH,PaCO2,PaO2 in the research group after treatment were (7.41±0.08),(51.26±12.13)mmHg,(77.28±15.34)mmHg,which in the control group were (7.26±0.07),(67.21±13.05)mmHg,(69.26±14.31)mmHg,compared with before treatment,pH and PaO2 of the two groups were increased,PaCO2 was decreased after treatment,and the three indicators of the research group were changed significantly better than those of the control group,the differences were statistically significant(t=11.2,7.11,3.03,all P<0.01).After treatment,HR and PR of the two groups were decreased,PEF was increased.The three indicators of the research group were also changed significantly better than those of the control group,the differences were statistically significant(t=3.13,8.58,5.45,all P<0.01).Conclusion Bilevel non-invasive mechanical ventilation in the treatment of COPD with respiratory failure has remarkable clinical effects,can significantly improve the patients' blood gas analysis index,HR,RR and PEF,and it is worthy of clinical application.

Objective To investigate the relationship between auxotypes,antibiotic resistance and plasmid of Neisseria gonorrhoeae. Methods 83 isolates of Neisseria gonorrhoeae from Chongqing during the period from January 1994 to November 1995 were examined.Results Eight auxotypes were detected in 83 strains. The prevalent auxotypes were proline requiring strains (51.8%) and nonrequiring (18.1%). The agar dilution method was performed to detect the susceptibility of 83 isolates to pencillin,tetracycline and spectinomycin, the results indicated that 15.6% of strains was penicillin resistant,70% was tetracycline resistant, 1.2% was spectinomycin resistant. Plasmid profile of 44 isolates,which was tested by rapid alkaline extraction method, showed that 70% of the strains carried 24.5 Md conjugative plasmid, 80% carried 2.6Md cryptic plasmid, 66% carried both 24.5Md and 2.6Md plasmids, and no plasmid was found in 16% of the strains. In Pro - strains both penicillin resistant strains and 24.5Md plasmid carrying strains were more common than other auxotypes (P

Objective To investigate the effects of different technical conditions on the microvesicle size,envelopment rate,morphology of surface and so on in order to select the best technical conditions to prepare HCPT(10-hydroxy-camptothecin)-loaded PLGA microvesicles.Methods Microvesicles were prepared by a water/oil/water emulsion and solvent evaporation method.Various factors related to the envelopment rate and micmparticle size were studied,such as the ratio of water phase and oil phase,ultrasound power,and time,stirring time and so on.Single factor experiments and orthogonal design testing was carried out to optimize the technology of microvesicles preparation.Results The best processing conditions for microvesicles preparation were as following: HCPT 25 mg,PLGA 1.875 g,the ratio of internal and external phases 1∶15,and the PVA concentration 3%.These preparative variables produced global,smooth and glossy microvesicles.Electric charges were probably between-40 to 0 mV,microvesicles sizes ranged from 500 to 1 000 nm,envelopment rate was 79.33%,drug loading to the microvesicles was 0.478 3%,and ultrasonic imaging was clear in vitro.Conclusion Our optimize technical conditions can prepare injectable microvesicles by ultrasound.

Cyanide can activate the N-methyl-D-aspartate (NMDA) receptor by two approaches directly and indirectly. Firstly cyanide-induced depletion of energy is associated with the activation of NMDA receptors indirectly by increasing extracellular glutamate (Glu) and affecting cytosolic Ca 2+ homeostatic mechanisms. Secondly most likely as a conditioner of the NMDA receptor, cyanide enhances NMDA receptors responses by modulating redox sites of cysteine residue located in the subunit NR 1 or NR 2 of the NMDA receptor. NMDA receptor-induced neurotoxicity, initiated by the direct or indirect activation of NMDA receptor, leads to neuronal injury, apoptosis or necrosis finally. Therefore, it is believed that the activation of the NMDA receptor is presumably the key event in the mechanism of cyanide-induced neuronal injures.

Objective To investigate the effect of health education on the family care for elderly patients.Methods Health education were done during family care for 65 elderly patients.A comparison was done between pre-intervention and post-intervention effect in terms of mastery of disease knowledge,health behavior,curative compliance and emotion management.Result The effect after intervention was significantly better than that before intervention (χ2=28.770,P<0.01).Conclusion During family care for elderly patients,health education is effective for the improvements of mastery of disease knowledge,health behavior,curative compliance,emotion management and ultimately the quality of life.

The neonatal period is important for the dramatic increment as well as function improvement of islet β-cell.β-cell mass augmentation is primarily regulated by neogenesis,replication,and apoptosis.The mechanisms involve cell cycle related proteins and mitosis-promoting signaling pathways.This remodeling period has far-reaching effects on the body in adapting to the metabolic needs and regulating glucose homeostasis later in life.

Objective:To invetigate the use of targeted anticancer drugs in our hospital during 2011-2013 to provide reference for the clinical rational drug use. Methods:The utilization of anti-tumor molecular targeted drugs in our hospital during 2011-2013 was retrospectively analyzed in respect of consumption sum, DDDs and DDC. Results:The proportion of consmption sum of anti-tumor mo-lecular targeted drugs in the total consumption sum was increased year by year, and that in 2012 and 2013 was over 60%. Protease ki-nase inhibitors accounted for 41. 29%-73. 41% in the consumption sum of anti-tumor molecular targeted drugs; monoclonal antibody accounted for 19. 40%-30. 88%; the other drugs accounted for 7. 19%-27. 83%. The consumption sum and the number of receiving medication patients of rituxan and cetuximab were not synchronized well, and the patients were born the higher cost. Conclusion:The use of anti-tumor molecular targeted drugs in our hospital is increased year by year, and the oral administration of anti-tumor molecular targeted drugs is with especially wide application.

The clinical data of 39 cases of idiopathic hyperaldosteronism (IHA) confirmed by operation were analyzed. The indications of operation consisted of (1) unable controlled the patients′ conditions by pharmacotherapy, (2) severe side effects due to high doses of medication and (3) difficulty in distinguishing between adenoma and nodule hyperplasia. The unilateral total adrenalectomy was suggested.
