Methods One hundred and twenty neotates with neonatal diaper dermatitis from August 2013 to July 2014 were randomly divided into the control group and experiment group, 60 cases in each group. The control group was treated with conventional care, while the observation group with recombinant bovine basic fibroblast growth factors combined with new rehabilitative liquid. The total effective rate and the treatment time were compared between the two groups. Result The total effective rate of the observation group was significantly higher than that of the control group (P<0.05) and the treatment time of the observation group was statistically significantly shorter than that of the control group (P<0.05). Conclusion Recombinant bovine basic fibroblast growth factors combined with new rehabilitative liquid is effective in the treatment of neonatal diaper dermatitis and it is worth promoting and using clinically.

Objective:To evaluate the quality condition and problems of acetylspiramycin at present. Methods:According to the standard described in Chinese Pharmacopoeia (2015 edition), acetylspiramycin and its preparations were determined, and the overall quality level of domestic acetylspiramycin was evaluated. The related substances, components and dissolution were analyzed to further explore the quality status. Results:In 258 batches of samples, the dissolution of only one batch did not meet the standard with the passing rate of 99. 6%. The results of exploratory research showed that the content of impurities in raw material was determined by the synthesis process, and the impurity profile of domestic and foreign formula was different. The dissolution behavior of domestic and for-eign formula in four kinds of media was not similar as well. Conclusion: The quality of domestic acetylspiramycin is promising. The research of related substances provides the reference for controlling the target impurities. The consistency assessment of dissolution pro-vides the reference for the formula process improvement and clinical application of acetylspiramycin tablets.

Pancreatic cancer is a highly malignant tumor and its treatment is still a challenge.Recent studies have shown that medication plays an important role in preoperative and postoperative adjuvant therapy for locally advanced pancreatic cancer and is also a major thera-peutic method for advanced pancreatic cancer.It can improve the survival time and quality of life in patients with pancreatic cancer.Tradi-tional chemotherapy regimens based on gemcitabine and fluorouracil have limited effects in the treatment of advanced pancreatic cancer,and studies on molecular targeted therapies have achieved some progress in recent years.With reference to related guidelines or consensus on the diagnosis and treatment of pancreatic cancer and important clinical trials of the treatment of pancreatic cancer,this article elaborates on the selection and therapeutic effect evaluation of chemotherapy regimens for pancreatic cancer.We believe that with the research and develop-ment of new drugs and the application of new techniques,the treatment of pancreatic cancer will achieve new breakthroughs in future.

Objective To explore the optimal method and condition for controlling release of vincristine (VCR) from VCR-loaded erythrocytes and enhancing the stability of carrier erythrocytes. Methods Erythrocytes were loaded into human erythrocytes using the modified hypotonic pre-swelling and isotonic resealing technique, and then with VCR, and they were treated with glutaraldehyde in concentration of 0.16% and 0.25% respectively. After storing at 4℃ for indicated time, the amount of VCR was determined with HPLC to compare their drug-release rate, and the degree of hemolysis in the supernatants was observed to compare the fragility of VCR-loaded erythrocytes treated with 0.16% glutaraldehyde with that with 0.25%, VCR-loaded erythrocytes treated with PBS, and VCR-loaded erythrocytes exposed to different hypotonic sodium chloride in different concentrations. Results The VCR-accumulated release rate increased in glutaraldehyde-treated VCR-loaded erythrocytes as well as untreated group during preservation. The VCR-accumulated release rate of 0.25% glutaraldehyde-treated group decreased by 71.67?4.20%, which was significantly slower than untreated VCR-loaded erythrocytes and 0.16% glutaraldehyde-treated group. After storing at 4℃ for 21 days, no significant changes at erythrocyte morphology was found in VCR-loaded erythrocytes treated with 0.25% glutaraldehyde, whereas untreated VCR-loaded erythrocytes and those treated with 0.16% glutaraldehyde can be stored only for 5d and 7.5d respectively. As compared to un-treated VCR-loaded erythrocytes, no significant change of osmotic fragility was seen in 0.25% glutaraldehyde-treated group, but significant increase in osmotic fragility was seen in 0.16% glutaraldehyde-treated group. Conclusion 0.25% glutaraldehyde could optimally block the membrane of VCR-loaded human erythrocytes and enhance their stability.
