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.

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.

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.

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

The expression of nm23-H1 and p53 genes were studied with ABC immunohistochemical method in 54 cases of gastric cancer and 57 cases of colorectal cancer. The result showed that the expression of nm23-H1 was 72.2% in gastric cancer and 64.9% in colorectal cancer, respectively. No significant difference was found between the expression of this gene and lymph node metastasis of the cancers. The mutant p53 protein expression was 53.7% and 52.6% in gastric and colorectal cancers, respectively. Although it was not correlated with lymph node metastasis, its expression was significantly higher in cancers with distant metastases, suggesting that the mutant p53 protein expression may be indicative of poor prognosis in gastrointestinal cancers.
