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.
2.Effect of one-time exhaustive exercise on individual' s mood states
Chinese Journal of Behavioral Medicine and Brain Science 2011;20(10):929-931
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.

Object The quality of Panax quinquefolius L from different origins were assessed in accordance with the contents of total ginsenoside and ginsenoide Rb 1 of them Methods The contents of total ginsenoside were determined by UV spectrophotometry, and the contents of ginsenoside Rb 1 were determined by HPLC Results Among the seven commercially available samples, the sample from Canada gave the highest content of total ginsenoside and ginsenoside Rb 1, the second is the samples from Huairou, Beijing, China. Conclusion Contents of total ginsenoside of all the seven samples are more than 4%, while content's of ginsenoside Rb 1 are more than 1%. And the more content of total ginsenoside is, the more content of ginsenoside Rb 1 is

Gallbladder cancer is a highly malignant tumor of the digestive tract with a poor prognosis. Currently, only radical surgical resection can achieve good results. As an important part of tumor adjuvant treatment and palliative treatment, radiotherapy has been widely used in the treatment of various malignant tumors and achieved certain effect. This article mainly reviews advances of radiotherapy in gallbladder cancer from four aspects: postoperative radiotherapy, preoperative neoadjuvant radiotherapy, intraoperative radiotherapy and palliative radiotherapy for gallbladder cancer.

I-scan technology is the newly developed image enhanced endoscopy technology from PENTAX,Japan,which can visualize the capillary and the gap of glandular duct of gastrointestinal mucosa.i-scan images are as bright as conventional white-light images.Therefore,i-scan is able to observe much larger areas in a distant view compared with NBI.It has a broad application prospects.However,due to the lack of a unified diagnostic standard,the application of i-scan technology needs further study.This review summarizes the applications of high-resolution electron-staining endoscopy in the diagnosis of gastrointestinal diseases.

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.
