Objective:Animal models were set up to explore the best preventative intra-nasal administration of interleukin 27 (IL-27)to diminish allergic airway inflammation of asthma and the related molecular mechanisms. Methods:Ninety-six female C57/6J mice were randomly divided into four groups,a group of the control group,a group of asthma group,and two groups of the prevention group. Based on being sensitizing and challenging with Ovalbumin ( OVA ) in the asthma model, two kinds of IL-27 administration asthma animal models were set up,one of which was low-dose-multiple preventive administration before OVA sensitization,one was low-dose-multiple preventive administration after OVA sensitization but before OVA challenge. Sacrificed the mice after challenging and analyzed the IL-5 and IL-13 levels in supernatant of Broncho alveolar lavage fluid( BAL) using ELISA;and HE stain and inflammation score were done for the lungs. Sacrificed the mice before challenging and used the lungs to analyze the level of total signal transducer and activator of transcription-1(STAT1) protein and phos-STAT1 based on the method of Western blot. Results: In low-dose-multiple administration before sensitization preventions group,IL-27 inhibits the secretion of IL-5 and IL-13(P<0. 05) and inflammation around bronchial and vascular obviously, and the inflammation score was lower than asthma group ( P<0. 05 ) , while another group has no significant effects ( P>0. 05 ) . The phosphorylation of STAT1 was impaired in mice after OVA sensitization, and preventative administration of IL-27 before sensitization could reverse the impairment of STAT1, whereas another group had no obviously changes. Conclusion:Preventative administration of IL-27 before sensitization can attenuate the airway inflammation in the mouse asthma model via reversing the phosphorylation of STAT1,while the mice which has been sensitized resisting the inhibition of IL-27 due to the impairment of the phosphorylation of STAT1 and already committed Th2-CD4+T cells existed in sensitization-mice airway might be the reason for such IL-27 resistance.

Objective To observe the efficacy and safety of tiopronin supplemented with chemotherapy in treating advanced breast cancer.Methods Sixty patients with advanced breast cancer were randomly divided into two groups:treatment group(n = 28) and control group (n = 32).Two groups were treated the same of NVB + DDP,the treatment group was supplemented with tiopronin,given for 10 days.Efficacy,toxicity in two groups were compared.Results The effective rate in the treatment group and the control group were 46.4% and 46.9% respectively, with no significant difference between the two groups ,P > 0.05.But the improved quality of life of patients in the treatment group was higher than that in the control group, P < 0.05.The rate of adverse reaction in liver function damaged (9.4%)and leucocyte lassitude(46.4%) were apparent lower than those in the control group(31.2% ,81.2% ),with significant difference between the two groups(P < 0.05, P < 0.01).Conclusion Tiopronin supplemented with chemotherapy show apparent effect in decreasing the adverse reaction of chemotherapy,improving the quality of life and not influence efficacy in advanced breast cancer.So tiopronln may act as protective drug for chemotherapy and deserve further testing in the clinic.

Objective To investigate the diagnosis and treatment of post-transplant lymphoproliferative disease (PTLD) after hematopoietic stem cell transplantation (HSCT).Methods Clinical data of one case of PTLD,including clinical manifestations,diagnosis and treatment,were retrospectively analyzed.And the related literatures were reviewed.Results From January 2007 to November 2012,one case developed PTLD among 196 patients who were followed up after HSCT in the First Affiliated Hospital of Chongqing Medical University.The incidence of PTLD was 0.5％.Clinical manifestations of the patient were not typical,including frequent fever,multiple lymphadenopathy and multiple pulmonary nodules.The patient was diagnosed as diffuse large B-cell lymphoma (B-DLCL) by pathological examination of the swollen lymph node.After withdrawal of immunosuppressants,the temperature returned to normal,and lymphadenopathy and pulmonary nodules disappeared completely.Conclusion PTLD is a severe complication of HSCT with distinctive morphologic and clinical characteristics.The origin of this disease may be associated with Epstein-Barr virus infection and imrnunosuppressive therapy.It needs the pathologic detection to make a definite diagnosis.Several different treatment strategies have been employed,and reduction of immunosuppressive therapy may lead to regression of PTLD.

Objective To explore the short and long-term effect of cardiopulmonary resuscitation (CPR) training for agricultural residence registration population with the language education and practice education,in order to establish a more effective method of first-aid training for agriculture population.Methods 989 agricultural residence registration people were divided into group A (721 people)and group B (268 people) randomly.Group A received CPR training with language education and group B adopted practice education.On the time before and after training immediatelythe 3rd and 6th month after training,we checked the training results and analyzed the data with statistical methods.Results The short- term effect of two methods was satisfying (accuracy more then 90％ ) and without statistical significance.The effect of group B was better than group A in the 3rd and 6th month after training.Two groups showed higher forgetting rate and some accuracy were less than 50％.Conclusions Agriculture population is in urgent need of first-aid.It may be a more effective method of first-aid training for agriculture population to transform gradually from language education to practice education.At the same time,we may use 4 hours as CPR practice education training time and 6 months as re-training period.

0.05),but the decrease of 2-hour postprandial blood glucose level and the increase of ISI in group A were superior to those in group B (P0.05).For the therapeutic effect,11 patients were cured,24 markedly effective,22 effective,13 ineffective and the total effective rate was 81.43% in group A;5 patients were cured,6 markedly effective,11 effective,13 ineffective and the total effective rate was 62.86% in group B.No obvious toxic and side effects were observed in the two groups during the treatment.【Conclusion】Yang-warming and spleen-strengthening therapy combined with antihyperglycemic drugs exerts a better effect on the treatment of insulin resistance in type 2 diabetes.

[ABSTRACT]OBJECTIVETo investigate the relationship between upper airway MRI parameters and the severity of patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Then the values of upper airway MRI parameters in waking state were assessed.METHODS The MRI upper airway parameters of 37 OSAHS patients and 18 nonsnoring normal subjects were measured and compared. Then data analysis were carried out to find out significant correlations between the MRI upper airway parameters and the severity of patients (the apnea hypopnea index, AHI; the lowest oxygen saturation, LSaO2; the oxygen desaturation index, ODI) with OSAHS.RESULTSThe correlation between cross-sectional areas and left-right diameter in the narrowest retropalatal region, the thickness of lateral pharyngeal wall, the length of the tongue, the length and thickness of the soft palate and the cross-sectional areas of the soft palate on midsagittal planes and severity of OSAHS were found (P<0.05).CONCLUSIONThe MRI upper airway parameters can be used in evaluating the severity of OSAHS in some ways, locating the obstruction sites and choosing the best treatment planning.
