ObjectiveTo explore the effect of salmeterol/fluticasone inhalation in treatment of children with asthma.Methods120 children asthma were divided into two groups at random.Each group had 60 patients.The control group used common therapy,while the observation group received inhalation of seretided.Check the pefr of children with Mini peak flow meter.The PEFR and clinical effect after 3 months were observedin two groups.ResultsThe diverse of PEFR of two groups before surgery had no significant difference(P ＞0.05).The PEFR of observation group was higher than control group in 1,2 months after surgery (t =4.92,5.02,5.38,P ＜ 0.05).The total effective rate of observation group was obviously higher than control group (90.9％ vs 62.1％,x2 =6.83,P ＜0.05).ConclusionSalmterol/fluticasone inhalation in the treatment of children with asthma had obvious clinical effect and could relieve the symptom quickly,which was worth using widely.

Objective To investigate the role of Wnt/β-catenin signaling pathway in migration ability of asthmatic rat airway smooth muscle cells (ASMCs).Methods The asthmatic rat airway smooth muscle cells were cultured in vitro.The expression of Wnt/β-catenin in ASMCs was detected by RT-PCR and Western blot.Migration ability of ASMCs was detected by wound healing assay and transwell migration assay.Results Compared with normal rats,the expression level of Wnt/β-catenin in chronic asthmatic rats ASMCs was obvious higher.The β-catenin signaling pathway by specific siRNA could reduce beta-catenin mRNA and protein expression level of ASMCs.The knockdown of Wnt/β-catenin was able to decreases the migration ability of ASMCs.Conclusion Abnormal activation of Wnt/β-catenin signaling pathway may participants in the migration ability of ASMCs of chronic asthma rats.

Objective To evaluate the effect of pelvic floor muscle training in postpartum urinary incontinence. Methods A total of 355 postpartum women 6 weeks after delivery were randomly allocated to training group ( 182 cases) and control group ( 173 cases). The training group attended in one to one pelvic floor muscle training conduction. The control group received the customary information. The two groups finished the questionaire 6 months after delivery to understand the general state of health, duration of pregnancy, urinary tract symptom and urinary incontinence 6 weeks,6 months after delivery. Results Ten cases failed, 4 cases lost in the training group and 6 cases lost in the control group. Significantly fewer women in the training group were reported stress urinary incontinence compared with the control group 6 months after delivery [11.3%(19/168) vs. 21.0%(35/167)](P＜0.01). Significantly fewer frequency of nocturia in the training group was reported compared with the control group 6 months after delivery [(1.3 ± 0.3) times vs.(2.2 ± 0.4) times ] (P ＜ 0.01 ). Conclusion Pelvic floor muscle training plays a positive role in postpartum urinary incontinence.

Objective To study the 3D CRT plan for hepatic tumors. Methods The 3DCRT plan of 50 cases of primary or metastasis hepatic cancer were designed according to the request of the doctors for CTV and the restricted receiving dose of the peripheral normal sensitive organs. The best plan was chosen referring the dose-volume histogram. Results By using ICRU dose reference point (the central point of tumor) as the dose 100 % and 80 % ~ 90 % dose line can be surrounded above 90 % of the PTV(planning tumor volume). The degree of 90 % dose line surrounding PTV was related to the scope of target area and its location. Conclusion The focus in different localization can be treated with different design when devise the treatment plan of the hepatic tumors. The reaction to radiotherapy was directly influenced by the volume of dosage of radiation to the normal hepatic tissues, and it also had great influence to the choice of prescription dose and the dose division style.

Objective To assess the clinical effect of colpomyomectomy.Methods 79 hysteromyoma patients who had indication of myomectomy were randomized into two groups.One group(42 patients) received colpomyomectomy,the other group(37 patients) received celiomyomectomy.Observing the clinical effect of intraoperation and postoperation between the two groups respectively.Results Comparing the colpomyomectomy group and celiomyomectomy group,the former operation time reduced(P

Objective To investigate the cause of pleural effusion in elderly patients on mechanical ventilation, and to analyze the effect of mechanical ventilation on hemodynamics. Methods 100 elderly patients admitted to our hospital from Jan 2002 to Oct 2004 who had received mechanical ventilation were studied retrospectively and logistic regression analysis of risk factors of pleural effusion before and after mechanical ventilation were performed. 8 patients of them were examined by ultrasonic cardiography before and during mechanical ventilation. Results Before mechanical ventilation there were 27 patients complicated with pleural effusion. After mechanical ventilation another 33 patients were showed to develop pleural effusion. Totally 60 mechanical ventilated patients had pleural effusion. The analysis of logistic regression showed that cardiac insufficiency was significantly correlated with pleural fluid in the patients receiving mechanical ventilation. The transmembrane pressure of tricuspid valve was increased during mechanical ventilation. Conclusion Incidence of pleural effusion increased, hemodynamics changed and the transmembrane pressure of tricuspid valve increased with mechanical ventilation in the elderly patients. Cardiac insufficiency was an important risk factor of pleural effusion.

Objective To observe nasal resistance in healthy adult people and patients with obstructive sleep apnea hypopnea syndrome (OSAHS), comparing the changes in nasal resistance after nCPAP treatment, and to explore the role of nasal resistance in development of OSAHS and the effect of nCPAP on nasal resistance. Methods Detection of nasal resistance was performed in 11 healthy people and 40 patients with OSAHS after completion of polysomnography (PSG). Three weeks after treatment with nCPAP, the patients received polysomnography and detection of nasal resistance again. Results Nasal resistance was higher in patients with OSAHS than healthy people [(0.27 ± 0.9)Pa/(cm3·s) vs. (0.21 ± 0.7)Pa/(cm3·s), t=-2.048, and P<0.05];nasal resistance was not related with age, BMI, neck circumference, waistline, AHI, MinSO2, and ODI (P>0.05). MinSO2, AHI and ODI were markedly improved three weeks after nCPAP therapy (P<0.05). Nasal resistance was increased from (0.27 ± 0.1) Pa/(cm3·s) to (0.43 ± 0.3)Pa/(cm3·s) after treatment (t = -2.733, P < 0.05). Conclusions Increased nasal resistance is one of risk factors for pathogenesis of OSAHS. Nasal resistance is not related with the severity of OSAHS. nCPAP can lead to an elevation in nasal resistance.

Objective To investigate the relationship between interleukin (IL)-17 and IL-10 in psoriasis.Methods The expression of IL-17 and IL-10 was measured by enzyme-linked immunosorbent assay in 32 patients with psoriasis (psoriasis group) and 30 normal controls (control group).The correlation of IL-17 and IL-10 was analyzed.Results The expression of IL-17 in psoriasis group was higher than that in control group[(57.59 ± 11.99) ng/L vs.(33.27 ± 6.49) ng/L] (t =9.84,P ＜ 0.01).The expression of IL-10 in psoriasis group was lower than that in control group [(25.38 ± 4.32) ng/L vs.(32.01 ± 5.54) ng/L] (t =5.27,P＜ 0.01).There was negative correlation between IL-17 and IL-10 in patients with psoriasis (r =-0.70,P ＜ 0.01).Conclusion The pathogenesis of psoriasis may be related to imbalance of IL-17 and IL-10.

Objective To investigate serum nesfatin-1 levels in type 2 diabetes (T2DM)patients with or without nonalcohol-ic fatty liver(NAFLD).Methods The hight,weight,serum GLU,lipid profiles,INS,HbA1c,ALT,nesfatin-1 levels were measured in 21 1 T2DM patients[98 without NAFLD(TD2M without NAFLD group)and 1 13 with NAFLD(TD2M with NAFLD group)] and 75 normal subjects(NGT group).BMI、HOMA-IR were also calculated.Results The serum nesfatin-1 level was significantly higher in T2DM group than those in NGT group(P <0.05),and T2DM with NAFLD group had higher nesfatin-1 level than T2DM without NAFLD group (P < 0.05 ).There was a close relation between nefastin-1 of T2DM group and course of disease (r=-0.447,P <0.05).NAFLD existed a significant correlation with BMI、TG and nesfatin-1 (P <0.05).Conclusion nesfatin-1 may partially contribute to the pathogenesis of T2DM and NAFLD.

OBJECTIVE To investigate nosocomial pulmonary infection in elderly patients receiving long-term(at least 30 day) mechanical ventilation. METHODS Retrospective survey was carried out in the aged patients with long-term mechanical ventilation,who admitted from Jan 2002 to Jun 2005.The risk factors of common pneumonia were studied by means of Logistic regression analysis. RESULTS In 69 cases with long-term mechanical ventilation,53 patients were caught common pneumonia(76.81%).Pulmonary tuberculosis and plural tuberculosis were(7(10.14%)) and(1(1.14%)),respectively.Nontuberculous mycobacterial infection was identified in 3 cases(4.35%).There were 8 cases suffered from Pneumocystis carinii pneumonia(11.59%).The length of mechanical ventilation and aspiration seemed to be the important risk factors for the development of common bacterial pneumonia. CONCLUSIONS The most significant preventive measures of common pneumonia include short mechanical ventilation and prevention of aspiration of gastric contents.Mycobacterium tuberculosis,nontuberculous mycobacteria and P.carinii induced pneumonia also should be considered in the elderly with(long-term) mechanical ventilation.
