Objective To summarize the clinical features and risk factors of children with post-infectious bronchiolitis obliterans (PBO), who were treated with invasive mechanical ventilation because of severe pneumonia, and to provide clinical reference for early diagnosis, early treatment and improvement of prognosis of pediatric patients with PBO. Methods The pediatric patients treated with invasive mechanical ventilation because of severe pneumonia, who were hospitalized in PICU of Tianjin Children's Hospital from October 2010 to December 2015 were included in this study. The pediatric patients who were diagnosed with PBO were used as the observation group. The general characteristics, clinical presentation, treatment time, treatment results, distribution of pathogens and relevant laboratory examination results were analyzed by using SAS 9.3 statistical software. Results A total of 73 pediatric patients were included in this study, including 49 male and 24 female, and their mean age was 8 months (P25-P75:4-12), the minimum age was 1 month and the maximum age was 36 months. They were divided into PBO group (n=30) and control group (n=43). It was found that wheezing (27 cases, 90.0%), persistent cough (22 cases, 73.3%) and exercise intolerance (22 cases, 73.3%) were the main clinical symptoms in PBO group. Results of physical examination showed wheeze (24 cases, 80.0%) and crackles (21 cases, 70.0%). Mosaic perfusion (25 cases, 83.3%) was the most prominent sign in lung CT scan. More than 2/3 of the pediatric patients were found moderate and severe pulmonary dysfunction. Pathogen detection rate was 50%in PBO group, and virus was prevalent (respiratory syncytial virus 4 cases, influenza virus 1 case, measles virus 2 cases and adenovirus 4 cases). The results of Logistic multivariate regression analysis showed that the risk factors included using corticosteroids at the beginning of disease (OR=8.515, 95%CI:1.948-37.224), prolonged mechanical ventilation (OR=1.116, 95%CI:1.031-1.327) and postponing clinic time (OR=1.114, 95%CI:1.010-1.227). Conclusion Once the severe pneumonia children, with the risk factors of using corticosteroids at the beginning of disease, prolonged invasive mechanical ventilation and postponing clinic time, are found the wheezing, persistent cough and exercise intolerance, and persisting wheeze and/or crackles, the PBO relevant examination should be executed as soon as possible to diagnosis and treatment.

Epithelial-mesenchymal transition (EMT) plays a critical role in the carcinogenesis of colon cancer,and promotes the tumor invasion and metastasis.Studies have shown several signals are involved including transforming growth factor-β (TGF-β),Wnt/β-catein,Notch,nuclear factor-κB (NF-κB) and PI3K/Akt signal pathway.It is important to elucidate EMT-related signal pathway thereby providing new insights into possible therapeutic interventions of colon cancer.

To observe the treatment of 50 female patients with climacteric insomnia by plum-blossom needle therapy. According to differentiation of symptoms and signs the head, back, belly and other location were tapping. Besides 50 patients were treated with Western medicine as a control group. The result showed the immediate and long-term effect in plum-blossom needle group was better than that in control group (P＜0.01).

One hundred patients were diagnosed with cervicalspondylotic radiculopathy definitely by symptoms, signs and X-ray examination. The therapeutic method was acupuncture of Jiaji(Ex-B 2) on the affected segment and the upper and lower vertebrae close together. After the arrival of qi, the needles were connected to acupuncture therapeutic instrument. Meanwhile, the numb, heavy and uncomfortable area on the shoulder and upper limb, where something like cord could be touched, was selected as Ashi point. The needle was inserted perpendicularly into the skin on the place that the cord was most obvious and inserted obliquely and deeply along the cord. After 3-4 courses of treatment, 90 cases got marked effectiveness and 10 cases got effectiveness.

BACKGROUND:Stent implantation is a common treatment for various cardiovascular diseases. Biodegradable AZ31 magnesium al oy stent is a new kind of biodegradable stent, but its degradation time and effect are stil rarely reported. OBJECTIVE:To investigate the degradation time and effect of AZ31 magnesium al oy stent in the rabbit aorta. METHODS:Twenty New Zealand white rabbits were subjected to implantation of biodegradable AZ31 magnesium al oy stents into the abdominal aorta. After implantation, the animals were grossly observed, and five animals were sacrificed under anesthesia at 1, 2, 3 and 4 months respectively for X-ray and histological observations. The number of residual struts was calculated under microscope. RESULTS AND CONCLUSION:X-ray findings showed that the implanted stent was found to be in complete form at 1 month after implantation, and its degradation was elicited at 2 months, indicating the stent lost its supporting role gradual y. The stent was degraded mostly at 3 months and degraded completely at 4 months. After implantation, the degradation rate of the stent was increased over time, which was confirmed by the X-ray findings. The number of residual struts was correlated with the time of degradation (r=-0.943, P<0.05). The slope of the linear regression equation was-0.12, based on which, the total time of the stent degradation was calculated to be 105 days. These results show that the AZ31 magnesium al oy stent implanted in the rabbit aorta is gradual y degraded with time, and the number of its residual struts exhibits an association with the degradation time. Given that the average number of degraded struts per day is 0.12, the complete stent is expected to be degraded within 105 days after implantation.

OBJECTIVE:To investigate the feasibility of mouse models establishment with kidney-positive deficiency with anti-sense oligonucleotide-loaded biodegradable polylactic acid microspheres. METHODS:Three-week old mice were randomized into groups A,B,C,D and E,with 6 mice in each group,where the mice in group A were given subcutaneous injection 0.2 ml nor-mal saline,and those in groups B-E were given subcutaneous injection 0.1,0.2,0.4 and 0.8 mg each mice of antisense oligonucle-otide-loaded biodegradable polylactic acid microspheres. After the administration,the weights and activities of mice in all groups were observed;and one month later,their livers,adrenal glands and brains were collected to detect the expression of glucocorti-coid receptor (GR) by real-time quantitative polymerase chain reaction (RT-PCR). RESULTS:All mice except those in group A were found to have kidney-positive deficiency symptoms such as developmental delay,light weight,less activities and gathering to-gether. Compared to group A,other groups showed lower GR expressions in liver,adrenal gland and brain. There was statistically difference (P<0.05). CONCLUSIONS:Antisense oligonucleotide-loaded biodegradable polylactic acid microspheres can inhibit GR expression,and the mice whose GR expression is inhibited show symptoms of kidney-positive deficiency,which provides a re-ference for the establishment of mouse models with kidney-positive deficiency.
