Objective To study the changes of the mood states at different time point of one-time exhaustive exercise.Methods16 participants were tested by POMS at the moments before,at,after recovery and after recovery 20 min of one-time exhaustive exercise.Results The scores of the 7 subscales got by 4 measures were used for one-way repeated measures analysis of variance.The results were showed that tension subscale scores (F (3.45) =0.335,P＞0.05,ES =0.022),anger subscale scores (F(3.45) =3.683,P＞0.05,ES =0.197),fatigue subscale scores (F(3.45 =0.863,P＞0.05,ES =0.054),depression subscale scores (F(3.45) =1.905,P＞ 0.05,ES =0.113 ),confusion subscale scores (F( 3.45) =0.601,P ＞ 0.05,ES =0.039 ) and self-esteem subscale scores (F(3.45) =2.804,P ＞ 0.05,ES =0.157 ) had no significant differences,but vigor subscale scores increased significantly (F(3.45) =8.778,P ＜ 0.01,ES =0.369).Conclusion One-time exhaustive exercises enhanced individual' s positive mood states.

Objective: To study the stability of forsythiaside. Methods: The stability of forsythiaside was studied by using UV spectrum obsiving the changes of spectrums in different conditions. Results: Forsythiaside was very unstable under the condition of alkali (pH=9.40), relatively stable at the pH=6.86, 60?Cand stable at the pH= 4.03 . Conclusion: The stability of forsythiaside can be affected by the condition of the acid, alkali and temperatures obviously.

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.

This article aims to study the present condition and disadvantages of current obstetrics and gynecology teaching and discuss the urgent needs and methods of evidence-based medicine (EBM) introduction to it.

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] This study examined the distribution and the expression of platelet-derived growth factor-A (PDGF-A) in the ligamentum teres of children with developmental dislocation of the hip (DDH) and normal persons in order to investigate the roles of PDGF-A in hip joint laxity. [Methods]There were six pairs of joint laxity of children with DDH and normal children (control group) matched to gender and age. Immunohistochemistry (SP method) method was used to detect the location and distribution of the PDGF-A in the ligamentum teres,and to semi-quantify their content.Semiquantitative RT-PCR method was used to detect the PDGF-A in the ligamentum teres at mRNA level. The quantitative analysis of the PDGF-A was performed by professional image software and the results were analyzed with standard statistical methods.[Results]High density expression was observed in the synovial layer with fibroblast regularly arranged parallel to the joint surface in the ligamentum teres. PDGF-A distribution was decreased in the fibrous layer of the ligamentum teres. There were significant differences in the percentage of positive fibroblast and gray-scale density in the fibrous layer between DDH group and control group (P

Objective To investigate the changes in Doppler perfusion index(DPI)of the liver and the platelet derived-endothelial cell growth factor(PD-ECGF)in patients with liver metastasis from colorectal carcinoma by determination DPI and PD-ECGF mRNA and protein expression levels.Methods One hundred patients were enrolled,including 50colorectal carcinoma patients(22of whom with liver metastasis and 28patients without liver metastasis)and 50healthy subjects as control.For all the objects involved,hepatic perfusion was documented with color Doppler flow imaging,and the DPI(hepatic arterial/total liver blood supply)was computed.The expression levels of protein and mRNA of PD-ECGF in 50specimens of carcinoma and adjacent tissues of colorectal carcinoma were assayed by immunohistochemistry and real-time fluorescence quantitative PCR methods in patients with colorectal carcinoma.Results According to pathology and imaging results,the DPI of colorectal carcinoma patients with liver metastasis was significantly higher than that in healthy control group and non-liver metastasis group(P0.05).According to the results of immunohistochemistry and real-time fluorescence quantitative PCR,the expression levels of PD-ECGF protein and mRNA were significantly higher in colorectal carcinoma than that in adjacent tissues(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.
