miR-205 is differentially expressed in tumor tissues and is closely related to tumorigenesis and tumor metastasis.miR-205 can regulate the biological behaviors of tumor cells such as cell proliferation,differentiation,in situ invasion and distant metastasis by post-transcriptional regulation through binding to targeted genes.Additionally,further research of miR-205 may be helpful for tumor diagnosis,targeted therapy and prognosis.

Autism is a neurodevelopmental disorder characterized by impairments in social skills, language, and behavior. It is now clear that autism is not a disease, but a syndrome characterized by phenotypic and genetic complexity. The etiology of autism is still poorly understood. Available evidence from a variety of sources strongly suggests that many genetic disorders are frequently associated with autism for their similar phenotypes. Based on this fact, this review begins by highlighting several principal genetic syndromes consistently associated with autism (fragile X, tuberous sclerosis, Angelman syndrome, Pader-Willi syndrome, Rett syndrome, Down syndrome and Turner syndrome). These genetic disorders include both chromosome disorders and single gene disorders. By comparing the similar phenotype, protein marker and candidate genes, we might make some breakthrough in the mechanism of autism and other genetic disorders.

Currently, about 300 million people worldwide are affected by asthma. Most of these sufferers inhale immunosuppressants (ie corticosteroids) and beta-adrenergic receptor agonists for their asthma treatment. However, about 5%-10% of patients of asthma have poor response to such treatment. Investigation of kinase signaling pathway and nuclear transcription factor as a target molecule in the treatment of allergic asthma has been the concern of scholars home and abroad. This paper reviewed inhibitors of kinase signaling pathway and nuclear transcription factors for the treatment of asthma.

[Objective To evaluate the teaching effects and advantages of problem-based learning (PBL) teaching mode based on network in the clinical practice of obstetrics and gynecology. Methods 2007 grade intern students in department of obstetrics and gynecology in Beijing Tongren Hospital of Capital Medical University were divided into 2 groups:control group (18 seven-year program and 11 five-year program)and experiment group (17 seven-year program and 10 five-year program). Traditional teaching was conducted in control group:interns and teacher completed teaching ward round several times according to the teaching requirement. PBL based on network was conducted in experiment group:tea-chers asking questions-data collection-learning and discussing-demonstrating and arguing-discussing and summarizing teaching process. Then the effects of different teaching methods were evaluated by clinical practice skill and theoretical test. SSPS13.0 statistical software was used for data analysis and measurement data were expressed as x±s. T test was conducted among groups. Results As for clinical practice skills, scores in PBL group (seven-year program and five-year program )were higher than those of traditional group [seven-year program:(190.47±2.30)vs (87.42±2.93);five-year program:(92.95±2.20)vs (90 . 09 ± 2 . 70 )] . There was no difference between the two groups in scores of theoretical test . In clinical practice skills,scores of general skill and clinic case analysis showed significant differences be-tween PBL group and traditional group. Conclusions PBL tea-ching mode based on network can improve the quality and effectiveness of the clinical practice of obstetrics and gynecology, especially in the social, technical,and knowledge dimension.

Objective To evaluate the outcome of valvular surgery in the elderly. Methods Between 1993 and 2004, 4546 patients underwent cardiac valve operation at our hospital. 252 patients (5.5%)(147 males, 105 females) were 65 or older [mean age (67.9?2.9) years]. Rheumatic valvular disease presented in 201(79.8%) patients and non-rheumatic valvular disease in 51 (20.2%). 56.0% of patients were in New York Heart Association (NYHA) functional class Ⅲ-Ⅳ.63 (25%) patients had aortic valve replacement (AYR), 93 (36.9%) had mitral valve replacement (MVR), 42 (16.7%) had mitral valve repair (MVP), 47 (18.7%) had AVR + MVR/MVP, and 7 (2.8%) had isolated tricuspid repair or replacement.34 (13.5 % ) had concomitant coronary artery bypass grafting (CABG) . Results Results The operative mortality was 9.1%, and the tendency of decline was observed in recent 3 years. As compared with the patients aged 16 to 64 years, the duration of mechanical ventilation, stay in ICU and in hospital postoperatively was longer [(30.6?42.8)h vs. (24.1?45.0) h,P = 0.02, (60.1?101.2) h vs. (43.0?70.6) h, P = 0.00, (25.7?41.3) days vs. (19.6?14.4) days,P=0.00]. In this group, the morbidity of postoperative complications was significant higher than that of the patients aged 16 to 64 years (10.6% vs.6.4% , P = 0.01). Preoperative NYHA function class was an important factor for postoperative mortality. Multivariate logistic regression showed that concomitant coronary artery bypass grafting (CABG) , AVR+ MVR/MVP, and prolonged cardiopulmonary bypass time, prolonged aortic cross-clamping time, postoperative acute renal failure demanding dialysis were significant independent predictors of operative mortality. Conclusion The mortality of cardiac valvular surgery in the elderly is acceptable. It is characterized by higher morbidity of postoperative complications and prolonged duration of stay in hospital. Concomitant CABG, AVR + MVR/MVP, prolonged cardiopulmonary bypass time, prolonged aortic crossclamping time and postoperative acute renal failure were significant independent predictors of operative mortality.

Objective: To investigate whether periodontitis might adversely affect the outcome of eradication of gastric Helicobacter pylori(Hp) . Methods: Ninety one patients with gastric Helicobacter pylori and periodontitis were enrolled. The patients were treated by medicine therapy, meanwhile 33 of them were treated by initial periodontal therapy. After treatment, the effect of initial periodontal therapy on the eradication of gastric( Hp ) was examined with 13 C urea breath test. The correlation between the gastric eradication rate and periodontitis was analyzed. Results: Four weeks and one year after medicine therapy, the eradication rate was singnificantly lower in the patients with PD≥4 mm than in those with PD

Objective To explore the relationship between the expression changes of cytokines, inter-leukin-6(IL-6), interleukin-8(IL-8), and tumor necrosis factor-α (TNF-α), and the wound time following explosive injury to rabbit’s chest. Methods The rabbit’s model of explosive injury was established. The expression levels of IL-6、 IL-8 and TNF-α in the plasma were detected by ELISA method at different wound time (0.5-12 h). Results The level of IL-6 increased at 3 h after wounding and reached peak at 6 h. The level of IL-8 increased at 1 h and reached peak at 6 h. The level of TNF-α increased at 0.5 h and reached peak at 3 h. Conclusion IL-6, IL-8 and TNF-α have a time-related expression after explo-sive injury.

Objective To evaluate the efficacy and safety of helmet delivered continuous positive airway pressure (Helmet-CPAP)for hypoxemia in airway extubated patients after cardiac surgery.Methods 120 adult patients in ICU from March 2014 to July 2015,who were after cardiac surgery,were enrolled.These patients who suffered hypoxemia within 48 hours after extubation,defined as that PaO2/FiO2 with oxygen mask could not reach 200,were divided into two groups.In the control group high concentration oxygen therapy with mask was delivered,while helmet-CPAP was delivered in the experimental group.Treatment duration was 6 hours.Results Helmet-CPAP significantly improved PaO2/FiO2 (144.35 ± 24.43 vs.201.35 ± 52.97,P ＜ 0.05) and left ventricular ejection fractions(0.5383 ± 0.0844 vs.0.5540 ± 0.0844,P ＜ 0.05).Breathing rate (22.60±5.08 vs.18.53 ±4.13,P＜0.05),heart rate(102.72±17.9 vs.95.15 ±13.79,P＜0.05)and shock index (0.85 ± 0.35 vs.0.75 ± 0.15,P ＜ 0.05) were significantly lower.The rate of using mechanical ventilation (6.67％ vs.28.33％,P ＜ 0.05) and length of ICU stay[41.0(25.0,67.5) hours vs.49.5 (32.5,90.8) hours,P ＜ 0.05] was significantly less than control group.Conclusion Helmet delivered continuous positive airway pressure is an effective and safe treatment for hypoxemia in airway extubated patients after cardiac surgery.
