Conclusion: The stability of forsythiaside can be affected by the condition of the acid, alkali and temperatures obviously.

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 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.

Objective To study the antitumor activity of betaine and its effect on the glycometabolism of S_(180) bearing mice. Methods On the basis of S_(180) bearing mice, taking tumor inhibition rate, the activity of LDH and ALD in serum as indexes which were determined by test kits. Results The different dosages for tumor inhibition rate of betaine are 39.8%, 25.7%, and 17.7%, respectively, betaine of high dosage can remarkably decrease the activity of LDH, and ALD (P

Objective To establish the quality control standards of Gehuang Huoxue Capsules. Methods TLC methods for identification of Radix Astragali and Radix Gentianae Macrophyllae were established. A simple HPLC method was established for the determination of Puerarin. Results The spots on TLC plates were clear without interference in the blank reference. The liner range of Puerarin was 0.020 79～0.665 2 mg/mL, r= 1.000 0. The average recovery of Puerarin was 100.1% and RSD=0.92%. Conclusion The method is simple, accurate, reproducible and can be used for the quality control standards of Gehuang Huoxue Capsules.

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.

[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
