Objective To explore the effect of nasal continuous positive airway pressure ventilation on severe respiratory disease and hypoxaemia. Methods In 30 neonates with severe respiratory disease-induced hypoxemia were managed with nasal continuous positive airway pressure, and corresponding nursing. Nasal continuous positive airway pressure before and after treatment, 24h arterial partial pressure of oxygen (PaO2), partial pressure of carbon dioxide (PCO2), PaO2/FiO2 and pH value in children were observed. Result After nasal continuous positive airway pressure ventilation, the levels of PaO2, post-PCO2, PaO2/FiO2 and pH value of children were better than the positive pressure ventilation before treatment and positive pressure ventilation (P < 0.05). Conclusions Nasal continuous positive airway pressure ventilation has good therapeutic effect on severe respiratory disease in children with neonatal hypoxemia. Good ventilation pressure regulation, skin and mucosa protection, prevention of vomiting in children with nursing to ensure the positive significance of continuous positive airway pressure therapy.

ObjectiveTo explore the relationship among resilience,attribution,and coping style for freshmen.Methods 977 freshmen were surveyed with Connor-Davidson Resilience Scale,Multidimensional-Multiattributional Causality Scale,and Simplified Coping Style Questionnaire,then compared different freshmen's resilience,attribution,and coping style,and analyzed their relationship.ResultsThe city freshmen showed significant higher resilience(68.88 ± 10.57 ),academic external attribution (21.14 ± 6.01 ),and interpersonal external attribution ( 22.87 ± 6.42 ) than rural freshmen ( ( 67.51 ± 10.43 ),( 19.81 ± 5.88 ),( 21.86 ± 5.88 ) respectively,t =2.03,3.48,2.57).Vocational freshmen showed significant higher academic internal attribution ( 28.68 ± 5.30 )and interpersonal internal attribution (26.81 ± 5.82) than undergraduate freshmen ( ( 27.61 ± 5.47 ),( 25.53 ±5.92),t =3.00,3.30).The only children showed significant higher resilience ( 68.88 ± 10.81 ) and academic failure luck (4.37 ± 2.21 ) than those having siblings ( (67.44 ± 10.18 ),(3.96 ± 2.12 ),t =2.15,3.02 ).Positive coping style,ncgative coping stylc,academic failure external attribution,academic success internal attribution,residence,and academic failure internal attribution had significant direct influence on resilience(β =16.435,- 4.919,- 0.344,0.308,1.396,- 0.182).ConclusionPositive coping styles and reasonable academic attribution can effectively predict great resilience of freshmen.

Nowadays, lung cancer has become one of the most common malignant tumors. The animal models of lung cancer have played very important role in the research on the etiology, diagnosis and treatment of human lung cancers. According to the preparation method, the animal models of lung cancer can be divided into spontaneous, induced, transplanted and transgenic models. The transplanted animal models are most commonly used. Transplanted animal models can be classified into heterotopic transplantation model and orthotopic transplantation model, each has its own characteristics. This article aims to introduce the research progress of transplanted animal models of lung cancer in recent years, focusing on the establishment of animal model, the improvement of preparation of animal model, the application of imaging in vivo in evaluating the animal model, the use of transplanted animal model in the study of interventional therapy, etc.

[Objective] To study the relationship between arthrochalasis and developmental dislocation of hip(DDH).[Methods]One hundred and seventy-six patients with DDH treated from Jaunary 2006 to December 2006 in the Shengjing Hospital of China Medical University were evaluated retrospectively.The average age was 3.54 years old(range,from 6 months to 15 years),with 153 females and 23 males.Eighty-four patients had both,58 left and 34 right.Totally 192 normal children were controls,and the average age was 3.67 years old(range,from 4 months to 15 years).The diagnosis of DDH was depended on clinical manifestations,radiography and ultrasonography.The criteria of arthrochalasia were the standards proposed by Wynne Davies.SPSS version 10.0 for Windows was used to perform statistical analysis.?2 test and spearman test was conducted for obtained data.A P

Objective To determine the pattern and incidence of congenital coronary anomalies (CCA) in adults undergoing coronary angiography. Methods The diagnostic angiographic data collected from October 2000 to October 2006 were reviewed, from which congenital coronary anomalies were found, and their angiographic features were studied. Results Among 1520 adults undergone coronary angiography, anomalous coronary arteries were found in 58 cases (3.82%). Depending on the anatomic characteristics of anomalous coronary arteries, these 58 cases were classified as following. Anomalies of origin and distribution were found in 26 cases (1.71%), among them separated origin of left anterior descending and left circumflex from left coronary sinus were found in 14 cases, left main trunk and left circumflex arising from right coronary sinus in 1 case for each, single left coronary artery in 2 cases, right coronary arteries arising from ascending aorta in 4 cases, from left coronary sinus in 3 cases, and from posterior coronary sinus in 1 case, respectively. Anomalies of coronary termination were observed in 11 cases (0.72%), and all of them were coronary artery fistulas. Anomalies of intrinsic coronary arterial anatomy in 21 cases (1.38%), among them myocardial bridge in 18 cases, hypoplasia of left circumflex artery in 2 cases, and sinus node artery arising from left posterior ventricular branch in 1 case. No anomalous collateral vessels were found. Conclusion Coronary angiography is one of the important methods of detecting anomalous coronary arteries. Classification based on the anatomic characteristics can help clarify the pattern and incidence of congenital anomalies of coronary arteries in adalts.

The aim of the study is to investigate the effects of concentration, intestinal segments, pH, inhibitors of proteins (P-gp), Na(+)-dependent glucose transporter (SGLT1) on the intestinal absorption of berberine, and to compare intestinal absorption of berberine in combinations. With phenol red as the indicator, in situ single pass intestinal perfusion (SPIP) model was used and intestinal absorption of pure berberine at concentrations of 36.70, 46.17 and 92.33 microg x mL(-1), simulated system of HLJDT (mixture of berberine, baicalin and geniposide), HLJDT with the concentration of berberine 92.33 microg x mL(-1) in perfusion solution of different intestinal segments (duodenum, jejunum, ileum, and colon) were determined by HPLC in combination with diode array detection (DAD). The results indicated that Ka values ofberberine at different concentrations had little significant difference among that obtained after perfusing via duodenum, jejunum, ileum and colon indicating that the absorption of berberine was mainly the passive diffusion. It was also suggested that SGLT1 and P-gp might exert some effects on the absorption of berberine. Ka and Peff values of berberine in a mixture of pure compounds and HLJDT for different intestine segments of rat showed an increasing tendency and was significantly different (P < 0.05) indicating that berberine in a mixture of pure compounds and HLJDT was assimilated better in small intestine. These results indicate that the intestinal absorption of berberine may be affected by compatibility of compounds. Additionally, berberine has wide absorption window and better absorption in colon.
