Pharmaceutical excipients are implementing registration and approval management in our country. As the disadvantages of the registration system appearing continuously, the demand for reform is getting higher and higher. The cry for drug master files ( DMF) model instead of registration and approval management is becoming more prominent. Based on the understanding of DMF sys-tem, the article discussed the positive roles of the excipients standards and guidelines construction in DMF implementation using phar-maceutical excipients supervision experience in the United States as the reference and starting from the standards and guidelines system of excipients, which aimed to provide suggestions for the supervision and management of pharmaceutical excipients, and improve the quality and safety of pharmaceutical excipients and drugs.

Objective: To observe and analyze the efficacy and safety of naloxone in the treatment of patients with pulmonary encephalopathy. Methods:50 patients with pulmonary encephalopathy were randomly divided into the observation group and the con-trol group. All the patients were carried out continuous oxygen with non-invasive ventilator. The control group was treated with the con-ventional treatment, and the observation group was given naloxone on the basis of conventinal treatment. The treatment course was 7 days. The clinical efficacy, clinical indicators and adverse events of the two groups were observed. Results:The total effective rate of the observation group reached 92. 00%, which was higher than that of the control group without statistical significance (72. 00%, P>0. 05). The levels of pH, PaO2, PaCO2, angiotensinⅡand IL-8 were significantly improved in both groups after the treatment (P<0. 05), and the improvement in the observation group was much better than that in the control group (P<0. 05). The incidence of ad-verse reactions of the two groups after the treatment showed no significant difference (P>0. 05). Conclusion: Early application of naloxone in the treatment of pulmonary encephalopathy can improve the clinical indices significantly with low incidence of adverse reac-tions and high safety, which is worthy of promoted use in clinics.

BACKGROUND:Artificial valve replacement for valvular disease has good biocompatibility and hemodynamic characteristics, but there are stil many factors that affect its therapeutic effects. OBJECTIVE:To detect the level of serum Apelin-12 in the perioperative period of valve replacement in valvular disease patients with atrial fibrilation. METHODS: Sixty-two patients with valvular heart disease scheduled for artificial valve replacement were selected, including 30 patients with persistent atrial fibrilation (atrial fibrilation group) and 32 patients with sinus rhythm (sinus rhythm group). There were 33 males and 29 females, with a mean age of (55±11) years. Levels of serum Apelin-12 and makers related to inflammation and oxidative stress were detected in two groups at admission. Furthermore, the sinus rhythm group was sub-divided into postoperative atrial fibrilation (POAF) group (n=8) and non-POAF group (n=24) after valve replacement, and the above-mentioned indicators were detected and compared between these two subgroups. RESULTS AND CONCLUSION:Compared with the sinus rhythm group, the serum level of Apelin-12 was significantly lower in the atrial fibrilation group, while the levels of high-sensitivity C-reactive protein and interleukin-6 and total antioxidant capacity were significantly higher in the atrial fibrilation group (P <0.05). Correlation analysis showed that the serum level of Apelin-12 was negatively correlated with high-sensitivity C-reactive protein level and total antioxidant capacity (r=-0.265,P=0.045;r=-0.960,P <0.001), but not correlated with the interleukin-6 level (r=-0.155,P=0.230). Compared with the non-POAF group, the serum level of Apelin-12 was significantly lower in the POAF group (P< 0.05), but the left atrial diameter, high-sensitivity C-reactive protein level were higher in the POAF group (P < 0.05). Apelin-12 may take part in the occurrence and maintenance of atrial fibrilation through the regulation of inflammations and oxidative stresses. The testing of serum Apelin-12 has a certain value in predicting the occurrence of postoperative atrial fibrilation.
